1	一种旱田用圆盘犁总成	CN201610181533.3	2016-03-28	CN105850236A	2016-08-17	黎健生; 林建辉
本发明公开一种旱田用圆盘犁总成，包括框架、上拉杆、压力弹簧、后推力轮、连接构件、连接杆、轴承座、凹形圆盘犁、刮刀、右下拉杆，框架上方右侧通过螺栓固定连接有上拉杆，框架左侧下方固定有后推力轮，后推力轮和框架之间还连接有压力弹簧，后推力轮右侧的框架上固定连接有多个连接构件，各个连接构件的间距相同，每个连接构件安装有轴承座，轴承座上安装有凹形圆盘犁，每个连接构件上还安装有一右下拉杆，右下拉杆上通过螺栓固定有右刮刀，右刮刀靠近凹形圆盘犁一侧呈圆弧形，右刮刀和凹形圆盘犁数量相对应。
2	Hydraulic down pressure control system for an agricultural implement	US13561934	2012-07-30	US20120305274A1	2012-12-06	Joseph D. Bassett
An agricultural row unit includes an attachment frame adapted to be rigidly connected to a towing frame, and a linkage assembly pivotably coupled to the attachment frame to permit vertical pivoting movement of the linkage assembly relative to the attachment frame. A hydraulic cylinder is coupled to the linkage assembly for urging the linkage assembly downwardly toward the soil, and an accumulator is mounted to the hydraulic cylinder for supplying pressurized gas to the hydraulic cylinder urging the linkage assembly upwardly away from the soil. A manifold is removably mounted to the hydraulic cylinder via a mounting interface, the manifold being selected from a group of different types of modular manifolds in which each manifold is removably mountable to the hydraulic cylinder, one at a time, via the same mounting interface, the manifold having two hydraulic-fluid ports including an inlet port and an outlet port.

A cultivator comprises an array of laterally-spaced soil-inversion discs having their centers arranged in a substantially horizontal line lying at not more than 30.degree. to a transverse plane of the cultivator and being mounted for rotation about individual axes which are equally inclined to the vertical and, when viewed in plan, also to the longitudinal plane of the cultivator.

PURPOSE: A seeding apparatus is provided to simplify the structure thereof and to facilitate the maintenance and repair thereof. CONSTITUTION: A seeding apparatus comprises a plow disc(40), a hopper unit(20), a discharge unit(30), a shutter power transfer unit, and a shutter actuating unit(50). The discharge unit is rotated by the power of a drive shaft and discharges fertilizer and seeds to the ground through each final discharge member. The shutter actuating unit comprises a shutter opening and shutting unit(56) which discharges seeds at an equal space. A shutter piece is opened and shut by the rotation of a touch rotating member which receives the power of the drive shaft.
