Description

A depth-covering soil scraping device

technical field

The patent of the invention relates to a depth-covering soil scraping device used in no-tillage and wide-width sowing operations of various crops such as wheat and rice, and belongs to the technical field of agricultural machinery.

Background technique

Conservation tillage has developed rapidly in our country. In conservation tillage technology, no-tillage seeding technology is the key. One of the key links in the promotion and implementation of conservation tillage system is no-tillage seeder and direct seeding machine with perfect performance and reliable quality. Etc., the same as the conservation tillage technology, the key to wheat wide planting is also wheat wide planter. Compared with ordinary seeders, no-tillage seeders, rice direct seeders and wheat wide-width seeders require better anti-blocking performance, and the soil working parts that form seed beds and affect the quality of sowing, such as ditch openers, Coverers, suppressors, etc. also have special requirements. At present, the seed belt rotary tillage seeder is the most widely used, and the wide-width seeding is also mostly used with the seed belt rotary tillage operation, which has good anti-blocking performance, but has high manufacturing costs, high power consumption, harsh working environment, and complicated operations. , large difference in sowing depth, and poor operation quality; although the disc opener has low manufacturing cost and good adaptability, it is especially suitable for no-tillage, with many straws and stubbles, but because of its W shape , The bottom of the ditch is uneven, the depth of sowing is not easy to control, the depth is different, and the width of the ditch is too narrow to meet the agronomic requirements, but it has not been applied. Once the above problems are solved, it will be widely used.

Contents of the invention

The object of the present invention is to provide a constant depth covering type soil scraping device which can overcome the above defects and realize wide width constant depth sowing.

The technical solution adopted by the present invention to solve its technical problems is: a kind of equal-depth covering type soil scraping device, including a shovel handle, a connecting plate, a front wing, a soil covering board, a soil pressing board, an empennage, a bottom plate, etc.; it is characterized in that: Suitable for no-tillage and wide-width sowing operations; the shovel handle, connecting plate, front flank, soil plate, soil pressure plate, rear wing, and bottom plate are welded into one, and the front flank, soil plate, soil pressure plate and bottom plate form an equal-depth covering scraper The soil surface and the front and rear wings form a lateral extrusion surface, which separates the fallen soil, pushes and scrapes the soil to both sides, shapes the back of the ridge, and finally forms a consistent U-shaped furrow, which realizes the equal depth and accurate covering of soil after sowing. It ensures the quality of sowing and lays the foundation for increasing crop yield.

The advantages of the equal-depth covering soil scraping device with the above structural characteristics are as follows: 1. The equal-depth covering soil scraping surface is composed of the front flank, soil cover plate, soil pressing plate and bottom plate, and the front cutting edge composed of the front flank and soil cover plate Separate the fallen soil, and use the cover plate and soil pressure plate to scrape and flatten the fallen soil to the middle to form a relatively flat W-shaped furrow surface with a slight height in the middle after planting. Deep in the middle and shallow; 2. The front wing and the tail form a lateral extrusion surface, the front wing pushes and scrapes the soil to both sides, the back of the ridge is formed by the shape of the tail, and finally a consistent U-shaped furrow is formed after shaping. The width L of the bottom of the groove is 60-300mm; 3. The intersection line between the front flank and the cover slab can be a straight line or a curve. The curve formula: y=0.0107x ³ -0.0518x ² -6.071x+57.048.

specific implementation plan

Embodiments of the present invention are described below in conjunction with accompanying drawings:

Shown in Fig. 1: 1. shovel handle, 2. connecting plate, 3. front flank, 4. earth covering board, 5. soil pressing board, 6. empennage, 7. bottom plate.

The equal-depth covering soil scraping device is composed of shovel handle (1), connecting plate (2), front wing (3), cover plate (4), soil pressing plate (5), tail wing (6), and bottom plate (7) by welding In one piece, the front flank (3), cover plate (4), soil pressure plate (5) and bottom plate (7) form the equal-depth covering scraping surface and the front flank (3) and rear wing (6) form the lateral extrusion surface ;Separate the falling soil, push and scrape the soil to both sides, shape the back of the ridge, and finally form a consistent U-shaped furrow, realizing the equal depth of accurate soil covering and sowing.

The front flank (3), soil cover plate (4), soil pressure plate (5) and bottom plate (7) form an equal-depth covering scraping surface, and the front edge formed by the front flank (3) and soil cover plate (4) falls back separately The soil cover plate (4) and the soil pressure plate (5) cooperate to scrape and flatten the falling soil to the middle to form a relatively flat W-shaped furrow surface with a slight height in the middle after planting. The δ of the slight height is 0-10mm to prevent the ridge wall The subsidence constitutes a situation where the two sides are deep and the middle is shallow.

The front wing (3) and the tail wing (6) form a lateral extrusion surface, and the front wing (3) pushes and scrapes the soil to both sides, and the back wing (6) is shaped to form a ridge back, and finally a consistent U-shaped furrow is formed after shaping. The width L of the bottom surface is 60-300mm.

The intersection line of the front flank (3) and the cover plate (4) can be a straight line or a curve, and the formula of the curve is: y=0.0107x ³ -0.0518x ² -6.071x+57.048.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be Modifications or equivalent replacements of the technical solutions without departing from the spirit and scope of the technical solutions of the present invention shall be covered by the scope of the claims of the present invention.
