Disc harrow is a traditional agricultural tool in agricultural production, and it was one of the agricultural tools that farmers needed. One of the Chinese martial arts equipment, evolved from agricultural tools. Iron rakes and rakes are as sharp as nails, aggressive and have the function of weapons. According to the working principle of the rake bucket, the circular plate rake uses groups of concave circular plates as working parts. The blade tip plane of the rake bucket is perpendicular to the ground, and has the forward direction of the unit and the adjustable deflection angle. When working, the rake piece rolls forward under the action of tractor traction force and soil reaction force, the rake blade cuts into the soil, cutting grass roots and crop stubble, so that the soil bed rises to a certain height along the concave surface of the rake piece and then turns over and falls down. When working, the surface fertilizer and pesticide can be mixed with the surface soil, and it can also be used for the cover seed work after the aircraft sowing. According to the configuration of the rake tooth group, it can be divided into three types: single row type, double row opposite type and offset type. Then, let's learn about the correct use of the disc harrow!
The existing disc harrow has a simple structure and adopts a folding harrow group structure. This kind of disc harrow group is easy to shake, the structure is unstable, the benefit of cultivated land is poor, and the maintenance cost is high.
Technical implementation elements:
1. Technical Problems to be Solved by Invention
The purpose of the present invention is to solve the shortcomings of poor efficiency and poor ease of use of the existing rake, and to provide a new rake with high arable land efficiency, large arable land area, good effect, convenient use, and long-term use of the rake will not loosen and its use method.
2. Technical scheme
In order to achieve the above object, the technical solution provided by the present invention is as follows.
The new disc harrow of the present invention includes a frame and a plurality of harrow groups detachably connected to the frame. The frame is welded by a plurality of stringers to form a square structure. The frame is provided with a traction frame along the direction of the axis of symmetry. The center is provided with an axle transversely, and one end of the axle is fixedly connected to the stringer of the frame, and the other end is connected to the axle, multiple rake groups are alternately arranged on both sides along the axis of symmetry of the frame, and the beams of two adjacent rake groups are 120
The frame is provided with a fixed seat, the connecting rod control mechanism uses the fixed seat as a fulcrum, one end is connected to the cylinder, and the other end is equipped with a spring to connect the axle.
A cylinder is fixed to the side frame in the center of the frame, and a connecting block is provided to a 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 rotates the axle.
Preferably, connecting plates are provided at both ends of the axle, the wheels are connected to the axle by 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, with the beams of the diagonally located rake groups being parallel.
Choose to set the pressure plate under the cross beam of the rake group, set the pressure plate on the side beam of the frame, and install two bolts between the pressure plate of the rake group and connect it on the frame.
Select two bolts to be located in the opposite top angle formed by the intersection of the beam and the side beam.
The tractor pushes the frame forward, the cylinder controls the wheels to rise, and the use of a new type of disc harrow in which multiple harrow groups work on the land.
3. Beneficial effect
1) It includes a frame and a plurality of rake groups detachably connected to the frame. The frame is formed by welding a plurality of stringers into a square shape. The frame is provided with a traction frame in the direction of the axis of symmetry. The center of the frame is made of a connecting rod. One end of the connecting rod control mechanism is fixedly connected with the frame stringer, the other end is connected with the axle, and the multi-rake groups are alternately arranged on both sides along the symmetry axis of the frame, the beams of two adjacent rake groups are at a 120 angle, and the lower position of the rake group is lower than that of the wheel. When the disc harrow is used, the arable land speed is fast, the arable land benefit is good, and the coverage rate is high.
2) In the new rake frame of the present invention, the oil cylinder is fixed on the side beam in the center of the frame, the piston rod of the oil cylinder is provided with a connecting block, the connecting block is fixedly connected with the axle, and the axle rotates through the expansion and contraction of the piston rod of the oil cylinder. This design speeds up the wheel launch speed, and at the same time makes the wheel launch more stable.
3) In the new disc harrow of the present invention, an angle of 60 is formed between the beams of the harrow groups adjacent to each other on the same side, and the beams of the harrow groups located at the opposite angle are parallel. The design not only reduces the resistance of the harrowing group of cultivated land, but also realizes the overall improvement of cultivated land, and the benefit of 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 wheels to rise, and the multi-harrow group works on the land, which has strong practicability, convenient use, convenient transportation, large arable land area and good effect.
The above is the correct use of disc harrow, if you need to know more, you can contact us at any time!

The correct use and maintenance of the disc harrow: in operation, the technical condition of the rake, scraper, square shaft, bearing, angle adjuster and connecting parts should be checked frequently, especially the end nut of the disc harrow group and the fixing bolts of each bearing. If it is found loose, tighten it in time, and remove the weeds and dirt on the workpiece in time.
How to maintain planter accessories
Planter A planting machine using crop seeds as a planting object. Planters for a certain type or crop are usually named after the crop type, such as wheat planter, cotton planter, etc. Planter accessories are very effective in farmland operations, so the planter accessories are easily damaged. Next, the planter manufacturer will introduce how to maintain the planter accessories. Before using the planter, we should have a simple and comprehensive understanding of the principles of all planter accessories. The planter manufacturer stated that it can be effective as long as the maintenance is carried out on the correct accessories to ensure the normal use of the planter accessories. The planter will extend its life.
