This invention relates to an apparatus for individual separation of small bodies, which is of application in precision sowing machines, the selection of seeds one by one being made by this apparatus continuously and quickly, said seeds being each laid in each corresponding compartment of the sowing plate in a much more advantageous manner than with known means which are presently used.
For facilitating a more detailed explanation and the understanding thereof, several drawings are enclosed, wherein a practical embodiment of the apparatus is shown, this embodiment being given by way of a non limitative example of the scope of the present invention.
In these drawings :
- Fig. 1 is a side and sectional elevation view of the apparatus.
- Fig. 2, 3 and 4 show details of construction which are characteristic of the apparatus in different phases of operation.
As it may be appreciated from the Figures, the described apparatus, applied to a precision sowing machine, comprises a frame mainly made of two upright stands 1 protruding from a base plate 2 which is fixed to the working table of the sowing machine above compartment plates 3 which are moved through suitable means below the apparatus.
At the top end of the upright stand 1, a block-piece 4 is articulated on an axle 4, in which block-piece a rank of boxes 6 is formed; through respective mouth-pieces of loading 7, joined to a cover 7a, seeds 8 are supplied in suitable amounts. Said block-piece 5 comprises in a forward area a rank of conical cavities 9 corresponding to the boxes 6, said cavities being formed by two semi- conical entrances 9a and 9b of corresponding plates 10 and 11 in a position wherein they are opposite and close together up to a point where they are applied one against the other (Fig. 1, 2 and 3), the plate 10 being fixed to the block-piece 5 while the plate 11 is movable with respect to the former one.
The apparatus comprises a pneumatic cylinder 10 which through a forked lower end 10a is articulated on an axle 10' provided on a lug 12 of one of the upright stands I, while through the end of its rod 13, it is articulated on an axle 14 in an area below the block-piece 5. From a position rearwardly inclined of said block-piece illustrated by Fig. 1, the cylinder 10 causes the oscillation of the block-piece forwardly, with the result that seeds 8 of the boxes 6 fill the conical cavities 9. Thereafter, through the cylinder 10 the oscillation of the block-piece 5 occurs rearwardly (Fig. 1 and 2) and immediately through tubes 15 provided inside the block-piece 5 and ducts 16 connected to said tubes, streams of air under pressure are insufflated into the cavities 9 (Fig. 3), said streams causing all the seeds 8 to come out said cavities, at the exception of one seed which stays obturating an aperture 17 in the bottom of the conical cavities in question.
The apparatus comprises a mechanism comprising a cylinder 18 which through the rod 19 hangs from the block-piece 5 and is articulated on the latter by means of an axle 20. Said cylinder 18 is joined to a wing 21 of a cam 22 which is hinged on the above-mentioned axle 4 on block-piece 5; said cylinder 18, after the single seed has been located in the aperture 17 of the bottom of conical cavities 9 as hereinabove indicated, causes the oscillation of the cam 22 so that the latter, by means of a side protrusion of the movable plate 11 pushes on this plate and separates it from the fixed plate 10, opening the lower aperture 17 of the conical cavities (Fig. 4). Then through this opening the seed passes, falling then into a corresponding hopper 23 of a rank of such hoppers provided in a piece 24 joined to the block-piece 5. The plate 11 is separated from the fixed plate 10 against the pressure of a spring 25 mounted on a rod 26 connected to the plate 10 and surrounding the plate 11, said spring bearing between the movable plate 11 and a head 28 of the rod 26; after the cavities 9 having been opened, the movable plate 11 returns to its original position.
The hoppers 23 comprise corresponding tubes 29 through which the respective individual seeds fall into corresponding mouths 30 provided in a sleeve 31 fixed to the upright stands 1; to these mouths 30 are connected other corresponding ducts 32 through which seeds are sent to lower holes 33 formed in a cross piece 34 supported by end arms 35 joined to the frame 1 below the plate 3 the compartments 36 of which coincide with the holes 33 for falling of corresponding individual seeds 8 into said compartments 36.
It is to be noted that the materials, forms and sizes of the components of the described apparatus can vary and many changes may be brought to this apparatus without departing from the scope of the present invention.
