Description

Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to a high-efficiency rotary tiller. Background Art

[0002] A rotary tiller breaks up the plow layer of soil, restoring the topsoil structure and making it softer, which is conducive to the growth and development of crop roots. The operation of a rotary tiller improves the soil's ability to retain moisture, increases soil permeability and air permeability, and provides a more favorable soil environment for crop growth. A rotary tiller effectively removes weeds and roots from fields, preventing them from adversely affecting crop growth and improving farmland utilization. With its powerful soil-crushing capabilities, a rotary tiller can finely break up the soil, evenly blend soil and fertilizer, and smooth the surface in a single operation, meeting the requirements for dryland sowing or paddy field planting. Rotary tillers are not only suitable for farmland cultivation, but can also be used for land preparation in orchards, lawns, parks, and green belts, providing excellent soil conditions for the growth of various crops.

[0003] During the operation of a rotary tiller, the soil contains relatively more water and is sticky. During the operation of the rotary tiller, clay will adhere to the furrowing blade, and the processed clay will also be relatively lumpy, affecting the effect of tilling the land. The looseness of the soil is also affected. Based on this, a more efficient rotary tiller is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4 The utility model provides a technical solution: a high-efficiency rotary tiller, including a housing 1 and a rotary tilling part 2, wherein the housing 1 is rotatably connected to the rotary tilling part 2, and the rotary tilling part 2 includes:

[0028] A rotating shaft 21 is rotatably connected to the housing 1;

[0029] The rotary tillage assembly 22 is fixed to the outer wall of the rotating shaft 21 and is used to loosen the soil;

[0030] The cutting assembly 23 is located outside the rotary tillage assembly 22 and is connected to the rotary tillage assembly 22. The cutting assembly 23 is used to cut the soil.

[0031] The rotary tillage assembly 22 includes a metal sleeve 221, a clamping piece 223 and a furrowing blade 224;

[0032] A second threaded hole 222 is formed on the outer side of the metal sleeve 221, and a first threaded hole 211 is formed on the outer wall of the rotating shaft 21. The metal sleeve 221 is sleeved on the rotating shaft 21, and the first threaded hole 211 cooperates with the second threaded hole 222 to fix the metal sleeve 221. The position is limited by tightening bolts in the first threaded hole 211 and the second threaded hole 222.

[0033] The clamping piece 223 is fixed to the outside of the metal sleeve 221, and the clamping piece 223 is used to limit the trenching knife 224, and the trenching knife 224 and the clamping piece 223 are fixed by bolts;

[0034] After the trenching blade 224 is damaged, one piece can be directly replaced and the rest can still be used.

[0035] The trenching knife 224 is made of metal and has a blade surface in the direction of rotation. The blade surface contacts and squeezes the soil, making it easier to crush the soil.

[0036] The outer end of the trenching knife 224 extends in an arc shape, and is used to lift the soil during rotation, so that the soil is broken after the trenching knife 224 passes through, and the soil is turned over.

[0037] The cutting assembly 23 includes a limiting sleeve 231 and a steel wire 232;

[0038] The limiting sleeve 231 is fixed to the metal sleeve 221 and is also sleeved on the rotating shaft 21. An elastic component is provided on the outer side of the limiting sleeve 231. The outer side of the elastic component is connected to the steel wire 232. The outer end of the steel wire 232 is fixed to the inner side of the arc of the trenching knife 224. The steel wire 232 is in a straight state.

[0039] The stretched steel wire 232 is squeezed against the soil along with the trenching knife 224, and after lifting the soil, it can also push the soil to make it more broken.

[0040] The elastic components are a sleeve rod 233, a sleeve 234 and a connecting spring 235;

[0041] The sleeve 234 is fixed to the outside of the limiting sleeve 231, the sleeve rod 233 is sleeved with the sleeve 234, the steel wire 232 is connected to the outside of the sleeve rod 233, and the connecting spring 235 is connected between the sleeve rod 233 and the sleeve 234, which is used to tighten the steel wire 232. The connecting spring 235 is used to tighten the steel wire 232. When the steel wire 232 is subjected to large resistance, the connecting spring 235 is stretched, so that the steel wires 232 are relatively loose, so that objects that hinder the steel wires 232 can pass through the loose steel wires 232, and relatively small stones can pass through between the steel wires 232.

[0042] There are multiple steel wires 232, which are arranged in an array. When loose, the multiple steel wires 232 are bent. The bent steel wires 232 can relatively increase the gap, allowing obstructing objects and objects that cannot be broken to pass between the steel wires 232, thereby avoiding damage to the steel wires 232 and improving the feasibility of operation.

[0043] The working principle of the utility model is as follows: the driving shaft 21 rotates, and the rotary tillage assembly 22 and the cutting assembly 23 are driven to rotate under the action of the rotating shaft 21. The metal sleeve 221 rotates to drive the furrowing knife 224 to rotate, thereby crushing the soil. The steel wire 232 is straightened under the action of the connecting spring 235. When the furrowing knife 224 rotates into the soil, the outer portion of the steel wire 232 also rotates into the soil, separating the soil and making the soil more broken. Even when the soil is sticky or has a lot of water, a good soil crushing effect is achieved.

[0044] Secondly, when encountering stones during rotation, the trenching knife 224 will be offset from the stones, minimizing damage to the trenching knife 224. After the stones are squeezed by the steel wire 232, the outer end of the steel wire 232 is fixed to the trenching knife 224 and cannot be deformed. The inner end of the steel wire 232 can pull the sleeve rod 233 to extend the connecting spring 235, thereby loosening the steel wires 232 and not being in a taut state, so that stones can pass through them to avoid jamming. Afterwards, the connecting spring 235 will recover to avoid damage.
