Description

No-tillage seeder for straw crushing and mulching

technical field

The invention belongs to the field of agricultural machinery, and in particular relates to a no-tillage planter for straw crushing and covering.

Background technique

The straw crushing and covering no-tillage seeder is one of the important machines for implementing no-tillage technology. The existing straw crushing and covering no-tillage seeders mostly use horizontal and axial hammers. This structure has a large resistance and is easy to block. . Simultaneously, the maneuverability and flexibility of the planter are poor in the operation process, and the operation is single, and the work efficiency is low.

Contents of the invention

In view of the defects or deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a straw crushing and covering no-tillage planter with high working efficiency, good maneuverability and flexibility in operation.

The technical solution for realizing the above invention is a straw crushing and covering no-tillage planter, which includes a straw crushing device and a seeding device, and the straw crushing device includes a frame, a gear box, and a depth-limiting wheel. The frame is installed in the middle of the upper side of the gear box, with a connecting plate on the top, upper suspension pins on the front side, lower suspension pins on the front side of the lower part, and rear suspension pins on the rear side; the depth-gauge wheel is installed on the gear box On the left and right sides; a steering gear is also installed on the top of the gear box, the power input shaft of the steering gear is connected to the universal joint, and the power output shaft passes through the gear in the gear box to connect with the tool holder. Installed with vertical and horizontal rotary cutters;

The power output shaft of the universal joint meshes with the gear;

The rear suspension pin is connected to the lower suspension arm installed on the front end of the sowing device frame through a connecting bridge; a hydraulic cylinder is installed on the connection plate, and the movable end of the hydraulic cylinder is connected to the upper suspension arm installed on the sowing device frame. arm connection;

The rear edge of the frame top is hingedly connected with the connecting rod, and the other end of the connecting rod is hingedly connected with the middle part of the upper suspension arm.

The hydraulic oil cylinder is installed obliquely, and its movable end is slightly lower.

The operating principle of the stalk of the present invention is crushed and covered with the seeder:

The working principle of the straw crushing device: the other end of the universal joint is connected with the power output shaft of the tractor, the power output shaft rotates, drives the universal joint to rotate, the universal joint drives the steering gear to rotate, and the power input connected The shaft rotates with the gear and the knife holder, thereby completing the straw crushing and covering operation.

The lifting of the straw crushing device is controlled by the oil cylinder installed on the tractor connected with the upper and lower suspension pins.

The straw crushing and covering no-tillage planter of the present invention can simultaneously complete two kinds of operations, the straw crushing operation is completed by the straw crushing device, and the no-tillage sowing operation is completed by the seeding device. When only one of the tasks is required, you can choose to raise the other device or unload it to reduce the load on the machine.

The lifting of the sowing device is controlled by the tractor and is installed on the hydraulic cylinder between the connecting plate of the stalk crushing device and the upper suspension arm of the sowing device.

The straw crushing and covering no-tillage planter of the present invention is applicable to straw crushing and covering returning to the field, straw crushing and covering returning to the field, sowing operations and lawn pruning operations.

Compared with the prior art, the stalk crushing and covering no-tillage planter of the present invention has the following advantages:

1. The straw crushing and covering no-tillage seeder of the present invention completes straw crushing and covering and sowing operations at one time, which improves work efficiency.

2. The stalk crushing and covering no-tillage planter of the present invention adopts three layers of cutting knives, which can crush the stalks into small joints, which is not easy to cause blockage.

3. The straw crushing and covering no-tillage planter of the present invention has good maneuverability and flexibility.
