摘要 | Inclined interpolation wide and narrow row spacing rice seedling transplanting mechanism belongs to agricultural machinery. A left power output shaft and a right power output shaft are correspondingly assembled on the left side part and right side part of the power transmission case, wherein the axes of the left power shaft and the right power output shaft are symmetrically arranged and incline downwards relative to the horizontal plane, and wherein the left transplanting mechanism and the right transplanting mechanism are perpendicularly attached to the left power output shaft and the right power output shaft respectively to form a V-shaped symmetrical structure with constant seedling taking space and narrow rice seedling transplanting space in the whole. A driven bevel gear is attached to the right power output shaft or the left power output shaft. A driving bevel gear on a main driving shaft in the power transmission case meshes with the driven bevel gear. A left bevel gear and a right bevel gear are respectively attached to the left power output shaft and the right power output shaft and the left bevel gear meshes with the right bevel gear mesh, wherein the transmission ratio is 1:1. It is realized in the invention that the left and right transplanting mechanisms both offset inward to plant the seedlings after they fetched the seedlings. It has simple structure and small space occupation, which makes the inward inclined narrow row transplanting possible. It needs low cost and easy installation. The row spacing is increased by 10 cm compared with the transplanted line. Therefore the connect seedling line has less possibility of hilling mud and dammed water and the seedlings avoid being pushed down. The invention is particularly suitable for general riding-type transplanters with high speed operation and integrated floating boards. | ||||||

说明书全文 | The present invention belongs to agricultural machinery, which mainly involved an inclined interpolation wide and narrow row spacing rice seedling transplanting mechanism and an automatic potted seedling transplanting mechanism in zigzag movement. Wide and narrow row spacing rice seedling transplanting can promote the ventilation among the plants and improve the illumination by adjusting the row space of the seedlings. And then it can not only prevent lodging and mitigate disease, but also achieve high quality and high yield, and decrease the cost and increase the efficiency. The present wide and narrow row spacing rice seedling transplanting mechanisms adopt different structure to fetch the seedlings from the seedling box and then offset outward to plant the seedling in wide row space. The row space between two adjacent transplanting mechanisms is narrow consequently. However the furthest side of the seedlings has wide row space during one direction transplanting. After the transplanter turns around at the edge of the field it has to run along the seedling line in a narrow row space. Therefore hilling mud and dammed water easily occur at the connect seedling line. Even the seedlings may be pushed down which affect the quality of operation. Further attention is drawn to The invention aims at solving the aforementioned problems of the present technology by designing an inclined interpolation wide and narrow row spacing rice seedling transplanting mechanism. The left and right transplanting mechanisms both offset inward to plant the seedlings after they fetched the seedlings. Therefore the connect seedling line will not have hilling mud and dammed water and the seedlings will not be pushed down. The objective of the invention is realized as follows. The inclined interpolation wide and narrow row spacing rice seedling transplanting mechanism consists of a power transmission case, a left transplanting mechanism and a right transplanting mechanism; a left power output shaft and a right power output shaft are correspondingly assembled on the left side part and right side part of the power transmission case, wherein the axes of the left power shaft and the right power output shaft are symmetrically arranged, and wherein the left transplanting mechanism and the right transplanting mechanism are perpendicularly attached to the left power output shaft and the right power output shaft respectively to form a V-shaped symmetrical structure with constant seedling taking space and narrow rice seedling transplanting space in the whole; a driven bevel gear is attached to the right power output shaft or the left power output shaft; a driving bevel gear on a main driving shaft in the power transmission case meshes with the driven bevel gear; a left bevel gear and a right bevel gear are respectively attached to the left power output shaft and the right power output shaft and the left bevel gear meshes with the right bevel gear mesh, wherein the transmission ratio is 1:1, and characterised in that the left power shaft and the right power output shaft incline downwards relative to a horizontal plane, and that the left and right transplanting mechanisms both offset inward to plant seedlings after they fetched the seedlings. It has simple structure and small space occupation, which makes the inward inclined narrow row transplanting possible. It needs low cost and easy installation. The row spacing is increased by 10 cm compared with the transplanted line. Therefore the connect seedling line has less possibility of hilling mud and dammed water and the seedlings avoid being pushed down. The invention is particularly suitable for general riding-type transplanters with high speed operation and integrated floating boards. Another technical problem to be solved by the invention is to provide an automatic potted seedling transplanting mechanism in zigzag movement based on the above technical scheme. Therefore another aspect of the invention can also adopt the following technical scheme:
In order to solve the above technical problems, another aspect of the invention can also adopt the following technical scheme:
The technology of potted seedling transplanting in zigzag arrangement can form good ventilation among the seedlings, improve the leaf photosynthesis and furthermore increase the yield. By incorporating the above technical scheme, potted seedlings can be transplanted in zigzag arrangement with wide and narrow row space automatically. It fills in a gap that there is no automatic potted seedling transplanter in zigzag arrangement and automatic potted seedling transplanter in zigzag arrangement with wide and narrow row space. Therefore the potted seedling transplanting in zigzag arrangement can be promoted from the manual cultivation stage to mechanization. It has the features of simple structure, low cost, reliable operation, good performance, small vibration and high efficiency. The features, functions and advantages that have been discussed can be achieved independently in various embodiments of the present invention or may be combined in yet other embodiments further details of which can be seen with reference to the following description and drawings. Many aspects of the invention can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present invention. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
In the following description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown, by way of illustration, various embodiments of the present disclosure. It is understood that other embodiments may be utilized and changes may be made without departing from the scope of the present invention. As shown in In the wide and narrow row spacing transplanting process, the power is brought to the driven bevel gear (4) from the main shaft (10) and the driving bevel gear (2) in the power transmission case (1). The driven bevel gear (4) makes the right bevel gear (5) rotate through the right power output shaft (6). Then the right bevel gear (5) makes the left bevel gear (9) rotate and further makes the left power output shaft (8) rotate. The left power output shaft (8) and right power output shaft (6) make the left transplanting mechanism (7) and right transplanting mechanism (3) rotate respectively. Finally the wide and narrow row spacing transplanting is achieved. In the inclined interpolation wide and narrow row spacing transplanting mechanism, the left transplanting mechanism (7) and right transplanting mechanism (3) fetch the seedling at the seedling holes and then offset a distance of e inward. Therefore the seedlings are planted in a narrow row space of b by the left transplanting mechanism (7) and right transplanting mechanism (3). Meanwhile the right transplanting mechanism (3) forms a wide row space of c with the left transplanting mechanism (7) of the adjacent assembly. The seedling rows at the furthest sides are narrow row space. So when the transplanter turns around at the edge of the field and conducts the next transplanting operation, the side seedlings will form a wide row space of d with the side seedlings planted in the previous operation. The invention can effectively finish the wide and narrow row spacing transplanting without hilling mud, dammed water and pushing down the seedlings. Referring also to In the accompany drawings, the denotation 100 represent the transplanted seedlings and the denotation 200 represent the trajectory of the left planting arm (7b-2) and right planting arm (3b-6). Referring also to The center gear, intermediate gear and planetary gear of the transplanting mechanism in the present disclosure are all non-circular gear. The planet carrier in the present disclosure is the installation frame of the gearbox of the transplanting mechanism. |
