Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tillage tools, in particular to a rotary tillage stubble removal and ridging structure. Background Art

[0002] Ridging refers to an agricultural technique of piling up soil on the ground to form strips of soil ridges for the purpose of planting crops, and stubble removal refers to the removal of the crop stubble left in the ground after harvesting. The Chinese utility model patent with application number CN202321697622.5 discloses a moisture-resistant no-tillage direct seeding structure for rapeseed, which uses a ridge-forming component to ridge the bed surface. During ridge forming, the fertilizer applicator and the rapeseed precision seed metering device operate simultaneously to achieve the combined operation of no-tillage ridge-forming and direct seeding fertilization. In addition, rapeseed seeds are sown in strips on the ridges, and rainwater flows into the ridge furrows to avoid waterlogging, which is beneficial to emergence and seedling formation, and greatly improves the one-time seedling formation rate of direct seeding. However, it only has a ridge-forming component and no related structure for stubble removal operations. If the soil has not been stubble-removed, the subsequent sowing effect will be poor. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the problem to be solved by the present invention is: to provide a rotary tillage stubble removing and ridge forming structure to solve the problem that the rapeseed direct seeding mechanism in the prior art lacks stubble removing tools.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses a rotary tillage stubble killing and ridging structure, comprising a cutter disc, a cutter holder and a cutter, at least two cutter holders are respectively provided on both sides of the cutter disc, each cutter holder is provided with a cutter, the cutter is L-shaped, the long side portion thereof is bent 40-50° toward one side of the plane where the short side is located, the short side is mounted on the cutter holder, the adjacent cutters on one side of the cutter disc have the same bending direction, and the adjacent cutters on the other side have opposite bending directions.

[0006] Preferably, the cutter disc is circular, a mounting hole is provided at the center thereof, and a plurality of dustproof plates are provided in the circumferential direction.

[0007] Preferably, the dustproof plate is arc-shaped, and a mounting groove that matches and is fixed to the outer shape of the edge of the cutter disc is provided on one side thereof close to the center of the arc.

[0008] Preferably, the knife seats are evenly distributed on the knife disc.

[0009] Preferably, the short side of the tool is bolted to the tool holder.

[0010] Preferably, the long side of the tool is bent 45° toward one side of the plane where the short side is located.

[0011] To sum up, due to the adoption of the above-mentioned technical scheme, the beneficial effects of the present invention are as follows: the rotary tillage, stubble removal and ridge-forming structure provided by the present invention can be installed on the existing rapeseed moisture-resistant and no-tillage direct seeding structure; the stubble removal knife can loosen the surface soil, crush the crop residues, and reduce water evaporation by cutting off the soil capillaries to conserve soil moisture; the ridge-forming knife can create field ridges, and the subsequent sowing effect of the field after the rotary tillage, stubble removal and ridge-forming structure operation is good.

[0016] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1

[0018] like Figure 1-3 The embodiment shown provides a rotary tillage stubble removal and ridge-forming structure, including a cutter disc 1, a cutter seat 3 and a tool 4. The cutter disc 1 is installed on the cutter shaft of the rapeseed planter in the prior art. At least two cutter seats 3 are provided on both sides of the cutter disc 1, and each cutter seat 3 is provided with a tool 4. The tool 4 is L-shaped, and its long side is bent 40-50° to one side of the plane where the short side is located. The bent part of the tool 4 is a blade for cutting soil. The short side is installed on the cutter seat 3. The adjacent tools 4 on one side of the cutter disc 1 have the same bending direction. The tool 4 on this side is the part used for ridge-forming. Since the tools 4 on this side have the same bending direction, the soil can be planed to one side to form a ridge structure when cutting. The adjacent tools 4 on the other side have the opposite bending direction. The tool 4 on this side is the part used for stubble removal. The remaining crop stubble in the soil is subjected to cutting forces in two different directions, and the stubble removal effect is good.

[0019] The method of using the utility model is as follows:

[0020] When the utility model is in use, it is installed on the rapeseed direct seeding mechanism, and the driving motor drives the cutter shaft to rotate. The rotation of the cutter shaft drives the cutter disc 1 thereon to rotate, and the rotation of the cutter disc 1 drives the cutter 4 to rotate, and the cutters 4 on both sides respectively realize the functions of ridge forming and stubble removing.

[0021] Example 2

[0022] like Figure 1-3 As shown, this embodiment is developed on the basis of the first embodiment in order to solve the problem of how the cutter disc 1 is installed on the cutter shaft of the rapeseed direct seeding mechanism in the prior art and to further improve the dust-proof effect of the cutter disc 1. Specifically, the cutter disc 1 is circular, and a mounting hole is provided at the center thereof. The cutter disc 1 is installed on the cutter shaft through the mounting hole. Several dust-proof plates 2 are provided in the circumferential direction of the cutter disc 1. By providing a dust-proof plate 2, the dust-proof ability of the cutter disc 1 in the circumferential direction is improved.

[0023] Furthermore, if Figure 1-3 As shown, the dustproof plate 2 is arc-shaped, and a mounting groove that matches the shape of the edge of the cutter disc 1 is provided on one side close to the arc center. The dustproof plate 2 is mounted on the cutter disc 1 through the mounting groove.

[0024] Example 3

[0025] like Figure 1-3 As shown, this embodiment is developed on the basis of the first embodiment in order to solve the problem of the cutter disc 1 not shaking during rotation. Specifically, the blade seats 3 are evenly distributed on the cutter disc 1, so that after the tool 4 is installed on the blade seat 3, the weight of the cutter disc 1 is evenly distributed, and it is not easy to shake during rotation.

[0026] Example 4

[0027] like Figure 1-3 As shown, this embodiment is developed on the basis of embodiment 1 in order to solve the installation problem of the tool 4. Specifically, the short side bolts of the tool 4 are connected to the tool holder 3, which makes it more convenient to install the tool 4. At the same time, when the tool 4 is damaged, it is also convenient to disassemble and replace parts.

[0028] Example 5

[0029] like Figure 1-3 As shown, this embodiment is developed on the basis of the first embodiment in order to improve the cutting effect of the tool 4 on the soil. Specifically, the long side of the tool 4 is bent 45° toward one side of the plane where the short side is located. By bending at 45°, the cutting effect of the tool 4 can be optimized.

[0030] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
