How to use the disc harrow correctly

Disc harrows are traditional farming tools in agricultural production, and were once one of the farm tools needed by farmers. One of the Chinese martial arts equipment, evolved from agricultural tools. Iron rakes and rakes are as sharp as nails, with strong aggressiveness, and they also function as weapons. According to the working principle of the rake bucket, the circular plate rake uses a group of concave circular plates as the working parts. The plane of the blade tip of the rake bucket is perpendicular to the ground, and has the forward direction of the unit and the adjustable deflection angle. When working, under the action of the traction force of the tractor and the reaction force of the soil, the rake blade rolls forward, and the rake blade cuts into the soil, cutting grass roots and crop stubble, so that the soil border rises to a certain height along the concave surface of the rake blade, and then flips and falls. When working, surface fertilizers and pesticides can be mixed with the surface soil, and they can also be used for cover seeding work after aircraft sowing. According to the configuration of the harrow tooth group, it can be divided into three types: single row type, double row opposed type and offset type. Then, let’s learn about the correct use of disc harrows!

The existing disc harrow has a simple structure, and the structure adopts the form of a folding harrow group structure. The disc harrow group is easy to shake, the structure is unstable, the farmland benefit is poor, it is easy to be damaged, and the maintenance cost is high.

Technical realization elements:

1. The technical problem to be solved by the invention

The purpose of the present invention is to solve the shortcomings of the existing rakes of poor efficiency and poor ease of use, and to provide a new rake and its use method that have high farmland efficiency, large farmland area, good effect, convenient use, and long-term use of the rake without loosening.

2. Technical solutions

In order to achieve the above objects, the technical solutions provided by the present invention are as follows.

The novel disc harrow of the present invention includes a frame and a plurality of harrow groups detachably connected to the frame. The frame is welded with a plurality of stringers to form a square structure. The frame is provided with a traction frame along the direction of the symmetry axis. The center of the frame is horizontally provided with an axle, and the two ends of the axle are provided with a wheel link control mechanism, one end of which is fixedly connected to the stringer of the frame, and the other end is connected to the axle. side, the beams of the two adjacent rake groups are 120

There is a fixed seat on the frame, and the connecting rod control mechanism takes the fixed seat as a fulcrum, one end is connected to the cylinder, and the other end is installed with a spring to connect the axle.

A cylinder is fixed on the side frame in the center of the frame, and a connecting block is arranged on the piston rod of the cylinder. The connecting block is fixedly connected to the axle, and the expansion and contraction of the piston rod of the cylinder makes the axle rotate.

Preferably, connecting plates are provided at both ends of the axle, the wheels are connected to the axle through the connecting plates, and the axle rotates the connecting plates around the axle.

Preferably, an angle of 60 is formed between the beams of adjacent rake groups on the same side, and the beams of the rake groups located at the opposite corners are parallel.

Choose to set the pressure plate under the beam of the rake group, set the pressure plate on the side beam of the frame, and install two bolts between the pressure plates of the rake group to be fixedly connected to the frame.

Select two bolts located in the opposite corners formed by the intersection of the beam and the side beam.

The tractor pushes the frame forward, the cylinder controls the wheel to rise, and the use of a new type of disc harrow in which multiple harrow groups work on the ground.

3. Beneficial effects

1) It includes a frame and a plurality of rake groups that are detachably connected to the frame. The frame is welded into a square shape by a plurality of stringers. The frame is provided with a traction frame in the direction of the symmetrical axis. There are wheels at both ends, and the center of the frame is made of connecting rods. One end of the connecting rod control mechanism is fixedly connected to the frame stringer, and the other end is connected to the axle. The multi-rake groups are alternately arranged on both sides along the symmetrical axis of the frame. The rake group beam is at 120 angle, and the lower position of the rake group is lower than the lower position of the wheel. When the disc harrow is used, the cultivated land speed is fast, the cultivated land benefit is good, and the coverage rate is high.

2) In the new type of rake of the present invention, the oil cylinder is fixed on the side beam in the center of the frame, and the piston rod of the oil cylinder is provided with a connecting block, which is fixedly connected with the axle, and the axle rotates through the expansion and contraction of the oil cylinder piston rod. The design speeds up wheel launch while making wheel launch more stable.

3) The new disc harrow of the present invention forms an angle of 60 between the beams of the adjacent harrow groups on the same side, and the beams of the harrow groups located at the opposite angles are parallel. The design not only reduces the resistance of the cultivated land in the harrow group, but also realizes the overall improvement of the cultivated land, and the benefit of the cultivated land is better.

4) The use method of the new disc harrow of the present invention, the tractor drives the frame forward, the oil cylinder controls the wheel to rise, and the multi-harrow group works on the ground, which has strong practicability, convenient use, convenient transportation, large arable land area, and good effect.
