Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an axial distribution structure for the blade shaft of a rotary tiller. Background Technology

[0002] When planting corn in low-lying, damp, and cold areas, some farmers use a method of removing straw from the field and rotary tilling to ridge the soil to optimize moisture dissipation. However, this method has some problems: First, the rotary tillage depth of the furrows and the cultivated area on the ridges is the same (15-20cm). Since no crops need to be planted in the furrows, only straw needs to be crushed and mixed with the soil. Rotary tillage that is too deep does not meet the "less soil movement" requirement of conservation tillage, and it also increases power consumption due to the large soil resistance, which is not conducive to cost savings. Second, the soil is wet and sticky and there are residual straws that have not been removed from the field. These straws are easy to stick to the shaft and even jam the rotating shaft, further increasing the resistance to operation. To this end, this structural innovation focuses on the axial distribution design of the rotary tiller's blade shaft. Based on the differentiated operational needs of the furrow and ridge cultivation areas, it is equipped with blade discs of different diameters and rotary tiller blades of different lengths. This allows the furrows to only achieve straw crushing and soil mixing, while the ridges achieve the cultivation layer depth required for crop growth. At the same time, anti-grazing and anti-clay components are added. This effectively solves the problems of grass entanglement and clay entanglement while reducing soil movement and power consumption, thus comprehensively improving the efficiency and economy of rotary tillage operations. Summary of the Invention

[0003] The technical problem this utility model aims to solve is to overcome the shortcomings of the prior art in rotary tillage and ridging operations, address the structural defects of the rotary tiller's cutter shaft in the existing technology, and develop an optimized axial distribution structure for the cutter shaft, thereby achieving the goals of reducing power loss, reducing the overall amount of soil moved, and preventing the rotary tiller shaft from being stuck by wet soil or residual straw.

[0004] The technical solution of this utility model is: an axial distribution structure of a rotary tiller blade shaft. Based on agronomic, ridge spacing, and ridge number requirements, a transitional rotary tillage area, a deep rotary tillage area, and a shallow rotary tillage area are set on the rotary tiller shaft. The transitional rotary tillage area is located on both sides of the rotary tiller shaft, while the deep and shallow rotary tillage areas are located between the transitional rotary tillage areas on both sides, arranged cyclically and sequentially. The transitional and shallow rotary tillage areas are equipped with small blade discs and short rotary tillage blades of the same specification, and the number of small blade discs and short rotary tillage blades controls the working width of the transitional rotary tillage area to be smaller than that of the shallow rotary tillage area. The deep rotary tillage area is equipped with a large blade disc and long rotary tillage blades, and the working width of the large blade disc and long rotary tillage blades is the same as that of the small blade disc and short rotary tillage blades, controlling the working width of the deep rotary tillage area to be similar to that of the shallow rotary tillage area. The shallow rotary tillage area has a uniform working width. The rotation diameter of the large blade assembly and the long rotary blade combination is greater than that of the small blade assembly and the short rotary blade combination, thus controlling the rotary tillage depth in the deep rotary tillage area to be greater than that in the shallow rotary tillage area and the excessive rotary tillage area. The anti-grass and clay component is located on the rotary shaft in the blank area without the small and large blade assemblies. It consists of a sliding sleeve and a gripping cone, and forms a sliding fit with the rotary shaft through the sliding sleeve. During operation, when the rotary shaft rotates at high speed, the anti-grass and clay component does not rotate synchronously with the rotary shaft, but only with the linear velocity of the rotary tiller's overall low-speed forward movement. When residual straw or wet soil adheres to the anti-grass and clay component and hinders its movement, the rotation of the rotary shaft is not interfered with because the anti-grass and clay component is slidably connected to the rotary shaft, allowing for continuous and stable operation.

[0005] 2. Preferably, the working width of the transition rotary tillage area is between one-third and one-half of the working width of the shallow rotary tillage area.

[0006] 3. Preferably, the rotary tillage depth of the deep rotary tillage operation area is between 15cm and 20cm.

[0007] 4. Preferably, the tillage depth of the shallow rotary tillage area and the transitional rotary tillage area is between 5cm and 7cm.

[0008] The beneficial effects of this invention are:

[0009] 1. It can reduce power consumption and application costs.

[0010] By selecting different types of blade combinations and rotary tillage blades in the furrow and ridge tillage areas respectively, and controlling different tillage depths, the overall power consumption of the rotary tiller can be reduced, thereby reducing power usage costs.

[0011] 2. Reduce material costs and the application and maintenance costs of rotary tillers.

[0012] In terms of material application, the combination of small-diameter blade disc and short rotary blades uses less material than the commonly used combination of blade disc and rotary blades, which can reduce the overall cost of the rotary tiller. In addition, the rotary tillage depth of this combination is less than the normal rotary tillage depth, resulting in less resistance during operation, fewer damages, and reduced maintenance costs for the rotary blades.

[0013] 3. It can reduce the amount of soil to be moved, which is conducive to soil conservation tillage.

[0014] By arranging a small-diameter blade disc and short rotary blades at the furrow, the rotary tiller designed according to the axial distribution method of the rotary tiller shaft of the present invention can move less soil than the existing commonly used rotary tillers, thus making it more conducive to conservation tillage.

[0015] 4. Effectively solves the problem of rotary tiller shafts getting stuck due to grass and clay getting tangled in them.

[0016] The area of ​​the rotary tiller without a blade disc is equipped with a biomimetic anti-grass and clay component. This component rotates asynchronously with the rotary tiller through a sliding connection, which reduces adhesion without affecting the operation of the rotary tiller and effectively solves the problem of grass and clay entanglement.

[0017] 5. It has a simple structure, low cost, and is easy to promote and use.

[0018] This method of axial distribution of rotary tiller blade shafts is simple in design, easy to promote and apply to the design of rotary tiller equipment, and facilitates widespread adoption. Attached Figure Description

The combination of the small blade (200) and the short rotary blade (300) controls the working width of the transition rotary tillage area (1) to be smaller than that of the shallow rotary tillage area (3); the deep rotary tillage area (2) is configured with a combination of a large blade (400) and a long rotary blade (500), and the working width of the combination of the large blade (400) and the long rotary blade (500) is the same as that of the combination of the small blade (200) and the short rotary blade (300) to control the working width of the deep rotary tillage area (2) to be the same as that of the shallow rotary tillage area (3). The width is the same; the rotation diameter of the combination of the large rotary blade (400) and the long rotary blade (500) is greater than that of the combination of the small rotary blade (200) and the short rotary blade (300), so that the rotary depth of the deep rotary tillage area (2) is greater than that of the shallow rotary tillage area (3) and the over-rotational rotary tillage area (1); the anti-weed and anti-clay component (600) is arranged on the blank area of ​​the rotary shaft (100) without the small rotary blade (200) and the large rotary blade (400), and it is composed of a sliding sleeve (600a) and a gripping cone (600b).
