Problems solved by technology

When there is a difference in emergence time, individual plants that develop early are taller and have well-developed root systems, and they will compete with late-emergent plants in the row for sunlight, water, and nutrients, resulting in less leaf area, higher leaf-to-stem area ratio, and dryness. Material accumulation is reduced, which ultimately reduces total output
[0009] To sum up, it is difficult to form good mulch quality and consistency of sowing depth only by pressing wheels, and it is impossible to form the soil environment of top pine and bottom solid plow layer required by agronomy.

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] Such as figure 1 As shown, in the present invention, the middle part of the bolt III6 is flexibly connected with the through hole IV35 and the through hole III31 of the crushing soil suppression arm 5, and the two ends of the bolt III6 are fixedly connected with the through hole II16 and the through hole I13 of the connecting frame 1; parallel double torsion springs The coil II 23 and coil I 21 of 4 are flexibly connected to the central part of the bolt III 6, the middle torsion arm 22 of the parallel double torsion spring 4 is limited by the groove 34 of the crushing arm 5, and the side of the parallel double torsion spring 4 The torsion arm I19 and the side torsion arm II20 are respectively limited by the groove I11 and the groove II12 of the connecting frame 1; one end of the bolt I2 is fixedly connected to the plate 7, and the other end of the bolt I2 is con...

Abstract

The invention belongs to the technical field of agricultural machinery and particularly relates to a seed furrow clod breaking roller. The middle of a bolt III is movably connected with two through holes of a clod breaking rolling arm. The two ends of the bolt III are fixedly connected with two through holes of a connecting frame. Two spring coils of a parallel double-torsion spring are movably connected with the middle of the bolt III, a middle torsion arm of the parallel double-torsion spring is limited by a groove of the clod breaking rolling arm, and two side torsion arms of the parallel double-torsion spring are limited by two grooves of the connecting frame. The two ends of one bolt are fixedly connected with a flat plate and the connecting frame, and the two ends of the other bolt are fixedly connected with the flat plate and the connecting frame. The upper outline of the clod breaking rolling arm is composed of an arc AH and an arc GH. The outline of the bottom surface of the clod breaking rolling arm is composed of a straight line AB, a curve BF and an arc FG, the curve BF is a part of a logarithmic spiral, the clod breaking rolling arm is provided with a hinge region, a transition region, a clod breaking region and a rolling region, and clod breaking teeth are arranged at the bottom of the clod breaking region. The soil contact component of the seed furrow clod breaking roller is free of soil adhesion, resistant to abrasion and long in service life, and the working effect and stability can be improved. When the seed furrow clod breaking roller is used in cooperation with a rolling wheel, seed covering quality and sowing depth consistency are high, and the yield of crops can be increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a compactor for crushing soil in seed ditch. Background technique [0002] Precision seeding is an advanced planting method and the only way to modernize agriculture. Precision sowing includes ditching, sowing, soil covering, and suppression. It is an extremely complicated and dynamic working process. Any link will affect the final distribution of seeds in the soil, thereby affecting the quality of sowing. Among them, the quality of seed coverage and the consistency of sowing depth determine the quality of sowing, which has an important impact on emergence and crop yield (Wang Jingli. Research on the position control of seeds after soil contact with precision seeder during soil covering and suppression[D]. Changchun : Jilin University, 2012). [0003] Good compression can improve the quality of seed coverage and increase the consistency of planting de...
