Description

Technical Field

[0001] This utility model relates to the field of corn planting technology, and in particular to a contour-following soil-breaking mechanism. Background Technology

[0002] A corn planter is an agricultural machine used for automated corn planting. Its main function is to quickly and accurately plant corn seeds at appropriate spacing and depth in farmland to improve planting efficiency and crop uniformity. The use of corn planters can significantly improve planting efficiency, reduce labor costs, and ensure proper seed placement in the soil, thereby increasing the yield and quality of the corn crop.

[0003] The contour-following soil-breaking mechanism is an important component of corn planters. It can precisely dig appropriate soil-breaking trenches during the planting process, ensuring that corn seeds are evenly and properly buried in the soil, thereby promoting crop growth and development. However, existing contour-following soil-breaking mechanisms all use linear blades, which not only have poor stubble-clearing and soil-breaking effects but also consume a lot of energy. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a contour-following ground-breaking mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The contour-following ground-breaking mechanism includes a cutting rod, a cutting disc, a straight blade, and a contouring blade. The cutting disc is fixed on the cutting rod, and two straight blades and two contouring blades are fixed on the outer periphery of the cutting disc.

[0007] As a further technical solution of this utility model, the blades are distributed on both sides of the transmission mechanism of the corn planter and connected by splines.

[0008] As a further technical solution of this utility model, the cutter disc is provided in four groups and evenly distributed on the cutter bar, with each group of cutter discs spaced 500-550mm apart.

[0009] As a further technical solution of this utility model, the straight blade and the copying blade are evenly distributed circumferentially on the outer periphery of the blade disc, and the straight blade and the copying blade are arranged alternately so that the blades form an inverted triangular sowing furrow on the ground and clear the seedling strip when working.

[0010] The beneficial effects of this utility model are: by using a contour-following soil-breaking mechanism to clear and break up the soil in the seedling strip, an inverted triangular sowing area is formed, which saves 21% of energy compared to the method of cleaning the seedling strip with straight blades.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see the appendix Figure 1 - Appendix Figure 2 The contour-following soil-breaking mechanism includes: a blade rod 1, a blade disc 2, a straight blade 3, and a contour-following blade 4. The blade disc 2 is fixed on the blade rod 11, and the straight blade 3 and the contour-following blade 4 are fixed on the outer periphery of the blade disc 2, with two pieces of each of the straight blade 3 and the contour-following blade 4.

[0016] In a preferred embodiment, the blades 11 are distributed on both sides of the transmission mechanism of the corn planter and connected by splines.

[0017] Please see the appendix Figure 1-2 In a preferred embodiment, the cutter disc 2 is provided in four groups and is evenly distributed on the cutter bar 11, with each group of cutter discs 2 spaced 500-550mm apart.

[0018] Please see the appendix Figure 1-2 In a preferred embodiment, the straight blade 3 and the imitative blade 4 are evenly distributed circumferentially on the outer periphery of the blade disc 2, and the straight blade 3 and the imitative blade 4 are arranged alternately so that the blades form an inverted triangular sowing furrow on the ground and clear the seedling strip when working.

[0019] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: by using a contour-following soil-breaking mechanism to clear and break up the soil in the seedling strip, an inverted triangular sowing area is formed, which saves 21% of energy compared to the method of cleaning the seedling strip with straight blades.

[0020] This utility model is intended to cover all such substitutions, modifications, and variations falling within the broad scope of the claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
