Description

Bionic fertilization opener

technical field

The invention relates to a ditching part on an agricultural tillage machine, in particular to a ditch opener for bionic fertilization.

Background technique

Fertilizer openers are an important component on seeders and fertilizer spreaders. Therefore, many scholars have conducted extensive research on it. The seeder requires that the fertilization ditch opener has a neat shape, the dry and wet soil are not mixed, the depth is consistent, and the fertilizer is spread evenly. However, when the fertilizer fertilization opener works in the soil with high humidity, the soil adheres to its working surface, which changes the surface shape, causes the traction resistance to increase, and makes the groove shape irregular, making the depth of the seeds in the groove Inconsistency affects the quality of fertilization and seeding. Therefore, reducing viscosity and drag is an important problem to be solved for fertilization openers.

Contents of the invention

The invention aims to solve the problems of large traction resistance and irregular ditch shape existing in existing fertilization ditch openers, and provides a bionic fertilization ditch opener with the function of reducing viscosity and resistance.

Studies have found that some soil cave animals such as musculus musculus, voles, mole crickets, dung beetles, pangolins, etc. have evolved well-developed digging feet, which have a very strong ability to dig caves, and have become the basis for mechanical digging, cutting, loosening and other methods on the ground. Based on the bionic research and design of soil-touching parts, ultra-high molecular weight polyethylene has excellent properties such as anti-sticking, wear resistance, impact resistance, chemical resistance, and self-lubrication that other engineering plastics cannot match, so ultra-high molecular weight polyethylene is used Hydrophobic materials such as ethylene and its composite materials are processed to manufacture bionic openers.

The present invention is the surface shape of the bionic earthworm's head in the shrinking state, and a regularly distributed bionic corrugated structure is formed on the surface of the core share base of the ditch opener. Its non-smooth cell density is high.

The bionic corrugated structure imitates the surface shape of the contracted state of the head of an earthworm.

Both the bionic corrugated structure and the core body are made of ultra-high molecular weight polyethylene or composite hydrophobic materials.

Beneficial effects of the present invention:

The invention has the effect of reducing soil resistance and power consumption; it can improve the quality of sowing and fertilization, and reduce the working resistance of ditching parts.

Detailed ways

Referring to Figures 1 to 4, in this embodiment, the surface of the core share 1 of the opener is distributed with a bionic corrugated structure 2, the bionic corrugated structure 2 is a prismatic bionic geometric structure, and the prismatic bionic structure on it Both the geometric structure unit and the base of the core share 1 are made of hydrophobic materials such as ultra-high molecular weight polyethylene or composite materials. The back of the base of the core share 1 has a cavity 3, and the prismatic bionic geometric structure unit has several through holes 4 and cavities. 3, the cavity 3 has an air inlet and a liquid inlet pipe 5.

The thickness D of the base body of the core share 1 is 2-4 mm; the height d of the convex rib is 1.7-2.6 mm, the width J is 4.6-7.4 mm, the width M of the groove is 1.1-1.8 mm, and the distance between the edge end of the convex rib and the shovel The distance between the body edge is 0-5mm, and the angle β between the convex rib and the cut soil surface is 80-100°.

The vertical side length H of the core share 1 is 80-140 mm, the horizontal side length L is 150-220 mm, the base thickness D of the core share 1 is 2-4 mm, and the material is ultra-high molecular weight polyethylene and its composite materials such as hydrophobic The material, the substrate and the protruding edge are processed into one body, and bonded together with the metal substrate, and the distance between the edge end and the edge of the shovel body is 0-5mm.

As shown in Figure 3, the inside of the core share 1 is a cavity 3. When the core share 1 of this structure is working, it can continuously inject air and liquid between the contact surface between the soil and the working parts to form an air-liquid interface, and change the soil and the machine. The interface contact condition of the working surface, so as to achieve the purpose of reducing soil adhesion. At the same time, by avoiding direct contact between the soil and the working parts and reducing the adhesion area, the frictional resistance between the soil and the working parts is reduced.

As shown in Figure 5, the vertical side length H of the core share 1 is 80-140 mm, the entry angle θ is 25-50°, and the clearance angle ε is 5°.

As shown in Fig. 6, the bevel angle γ of the core share 1 is 60-75°, and the width B is 120-180 mm.
