Description

A notched disc harrow

technical field

The utility model relates to a disc harrow, in particular to a notched disc harrow, which belongs to agricultural equipment machinery.

Background technique

The notched disc harrow is based on the principle of harrowing, with a group of concave discs as the working part. The cutting edge plane of the harrow blade is perpendicular to the ground and has an adjustable deflection angle with the forward direction of the unit. During operation, the rake rolls forward under the action of tractor traction and soil reaction force, the cutting edge of the rake cuts into the soil, cuts off the grass roots and crop residues, and makes the soil rise along the concave surface of the rake to a certain height and then turns over and falls. During the operation, the fertilizer and pesticide on the surface can be mixed with the surface soil. It is generally used for shallow plowing and stubble removal after crop harvest, moisture conservation in early spring, and crushed soil after plowing. It can also be used for cover seeding after aircraft sowing.

However, the existing notched disc harrow cannot be freely adjusted within a range of 30 degrees, which is inconvenient for the harrowing work, and the quality of the harrowing work is poor. The existing notched disc harrow cannot be manually raised and lowered, which is inconvenient for the two Ground wheels are used to adjust the height (elevating operation, lowering and pulling away), which is not easy to use.

Utility model content

The utility model proposes a notched disc harrow, which solves the problems in the prior art that the notched disc harrow has a single function, cannot be adjusted freely within 30 degrees and cannot be manually lifted, and makes the function of the notched disc more comprehensive and easy to use. It is more convenient to get up and effectively improves the quality of harrowing work.

In order to solve the above technical problems, the utility model provides the following technical solutions:

The utility model relates to a notched disc harrow, which comprises a frame, tires and disc harrows. The disc harrows are movable on both sides of the bottom end of the frame. Two tires are fixed on the frame through a rotating shaft, an adjusting rod is fixed at the middle of the rotating shaft between the two tires, and a traction rod is fixed on one side of the frame through a connecting piece.

As a preferred technical solution of the present invention, the included angle between the two disc harrows and the frame is 90°-130°.

As a preferred technical solution of the present invention, a plurality of rake knives are evenly arranged on the two disc harrows, and the rake knives are all made of stainless steel.

As a preferred technical solution of the present invention, a connecting rod is fixedly arranged on the towing rod, and one end of the connecting rod is fixedly connected with the frame.

The beneficial effects achieved by the utility model are: the utility model has the advantages of simple structure, low cost, and strong practicability, and disc rakes are movable on both sides of the bottom of the frame, which can facilitate the disc rakes to move within a range of 30 degrees. Free adjustment facilitates the harrowing work and improves the quality of the harrowing work; an adjustment rod is fixed in the middle of the shaft between the two tires, which is convenient for adjusting the height of the tire through the adjustment rod, which is convenient for lifting operations and lowering. easy to use.

detailed description

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Example 1

As shown in Figure 1-3, the utility model provides a notched disc harrow, including a frame 1, a tire 3 and a disc harrow 6, both sides of the bottom of the frame 1 are movable with a disc harrow 6, two Two tires 3 are fixed between the disc harrows 6 and on the frame 1 through the rotating shaft, and the middle part of the rotating shaft between the two tires 3 is fixedly provided with an adjusting rod 4, and one side of the frame 1 is fixedly provided with a connecting piece tow bar 2.

Further, the included angle between the two disc harrows 6 and the frame 1 is 90°-120°, which facilitates the free adjustment of the disc harrows within a range of 30° and facilitates the harrowing work.

Multiple rake knives are evenly arranged on the two disc harrows 6, and the rake knives are all made of stainless steel. Multiple rake knives can effectively increase the area of harrowing work and improve work efficiency. The stainless steel material The rake has strong compression and corrosion resistance, which can effectively increase the service life of the rake.

The drawbar 2 is fixedly provided with a connecting rod 5, and one end of the connecting rod 5 is fixedly connected with the frame 1, so that the connecting rod 5 is used for adjusting the depth of the plowed soil, and is convenient for harrowing work.

The utility model has the advantages of simple structure, low cost and strong practicability. The disc harrow 6 is movable on both sides of the bottom end of the frame 1, which can facilitate the free adjustment of the disc harrow 6 within a range of 30 degrees, and facilitates harrowing. The progress of the work improves the quality of the raking work; the middle part of the rotating shaft between the two tires 3 is fixed with an adjustment rod 4, which is convenient for adjusting the height of the tire 3 through the adjustment rod 4, which is convenient for lifting operations, lowering and pulling away, and is convenient to use.
