Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a micro-tiller blade and cutting tool. Background Technology

[0002] The main working component of a mini tiller is the rotary tiller blade, which directly tills the farmland through rotation and forward movement. The specific working process includes the rotary tiller blade rotating, cutting into the soil, throwing soil, and moving forward. In the conventional design of rotary tillers, each blade typically has only one bent cutting edge for breaking up soil. When breaking up soil with a single bent cutting edge, the soil clumps are relatively large, and the soil breaking effect is not ideal. Furthermore, when weeding, a single cutting edge is prone to getting tangled, which affects the throwing of soil. To improve this situation, some irregularly shaped blades exist, which clamp more blades in the same mounting position or make further welding modifications to the blades to improve rotary tillage and cutting effects. However, this operation increases the overall weight of the blade, and the other components welded to the blade have poor overall structural strength, and the welding efficiency and cost are high. For the mass production of blades and cutting tools, this increases the labor and material costs.

[0003] There is still considerable room for improvement in the overall structure, and a technical solution urgently needs to be developed to address the aforementioned technical issues. Utility Model Content

[0004] The purpose of this utility model is to provide a micro-tiller blade and cutter that can achieve double-edged rotary tillage, improve soil breaking efficiency, reduce soil clod residue, enhance weed breaking and weeding effect, reduce weed entanglement, and improve the overall efficiency and quality of tillage and rotary tillage of wasteland.

[0005] To achieve the above objectives, this utility model provides the following technical solution; A mini-tiller blade includes a handle portion and a cutting edge portion; the cutting edge portion includes a first cutting edge and a second cutting edge extending from the handle portion; the first cutting edge and the second cutting edge have opposite bending directions; the handle portion is provided with a mounting structure.

[0006] Furthermore, the handle portion includes a heel portion and a blade portion, wherein the first cutting edge, the second cutting edge, the blade portion, and the heel portion are integrally formed; the mounting structure is a mounting hole.

[0007] Furthermore, both the first and second cutting edges are curved.

[0008] Furthermore, the outer side of the first blade is connected to one side of the blade body and gradually thins to form a ground-breaking blade; the inner side of the second blade gradually thins to form a secondary blade.

[0009] Furthermore, the horizontal projections of the heel and the blade are in a straight line; the bending directions of the horizontal projections of the first and second blades are symmetrically distributed with respect to the blade.

[0010] Furthermore, the horizontal projections of the heel and the blade are in a straight line; the bending direction of the horizontal projection of the second blade is perpendicular to the blade.

[0011] Furthermore, the blade height a of the first blade and the blade height b of the second blade are both 61mm to 65mm; the total length of the heel, the body, and the blade is 250mm to 260mm.

[0012] A tiller blade, equipped with the aforementioned tiller blade, includes a main shaft with multiple mounting discs, on which the tiller blade is detachably mounted.

[0013] Furthermore, the tool holder is provided with a clearance groove for avoiding the spindle.

[0014] Furthermore, the installation distance h between two adjacent mounting discs is not greater than the sum of the cutting height a of the first cutting edge and the cutting height b of the second cutting edge.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The blades and cutters of this mini tiller have a simple basic structure. The handle is used for the overall installation and assembly of the blades. The mounting structure allows for quick and easy disassembly and installation, facilitating the replacement and maintenance of damaged or malfunctioning blades. The first and second blades are bent in opposite directions, allowing for double-bladed rotary tillage with just one blade. The reverse bending of the double blades improves soil breaking efficiency, reduces soil residue, and enables bidirectional throwing and turning of the soil. During tillage, the double blades can counteract the lateral force of the soil on the blades, significantly reducing overall blade vibration during operation and extending blade life. Furthermore, the reverse double-bladed structure also improves weed breaking and removal, reduces weed entanglement, and overall improves the efficiency and quality of tillage and rotary tillage of wasteland.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1, Reference Figures 1-3 As shown, this utility model provides a micro-tiller blade, including a handle portion 30 and a blade portion 33; the blade portion 33 includes a first blade 331 and a second blade 332 extending from the handle portion 30; the first blade 331 and the second blade 332 have opposite bending directions; the handle portion 30 is provided with a mounting structure.

[0019] The basic structure of this mini tiller blade is simple. The handle 30 is used for the overall installation and assembly of the blades. The installation structure allows for quick and easy disassembly and installation, facilitating the replacement and maintenance of damaged or malfunctioning blades. The first blade 331 and the second blade 332 adopt opposite bending directions, enabling double-bladed rotary tillage with just one blade. The reverse bending of the double blades improves soil breaking efficiency, reduces soil clod residue, and allows for bidirectional throwing and turning of the soil. During tillage, the double blades can counteract the lateral force of the soil on the blades, significantly reducing overall blade vibration during operation and extending blade life. Furthermore, the reverse double-bladed structure also improves weed breaking and removal effects, reduces weed entanglement, and overall improves the efficiency and quality of tillage and rotary tillage of wasteland.

[0020] In this embodiment, the handle portion 30 includes a heel portion 31 and a blade portion 32. The first cutting edge 331, the second cutting edge 332, the blade portion 32, and the heel portion 31 are integrally formed. The mounting structure is a mounting hole 312.

[0021] Specifically, the first cutting edge 331, the second cutting edge 332, the blade body 32, and the heel part 31 are integrally stamped from strip material, which has a stable structure, improves the structural strength of the blade, and has high processing efficiency.

[0022] In this embodiment, both the first blade 331 and the second blade 332 are curved. Specifically, the curved shape is more conducive to the newly turned soil pushing other soil that has been swirled up during rotary tillage to the side, avoiding the accumulation of damp soil or weeds, and improving work efficiency.

[0023] In this embodiment, the outer side of the first blade 331 is connected to one side of the blade body 32 and gradually thins to form a soil-breaking blade 34; the inner side of the second blade 332 gradually thins to form a secondary blade 35. Specifically, the soil-breaking blade 34, which is connected to the first blade 331 at the blade body 32, can further improve the soil-breaking ability, reduce blade wear, and improve the efficiency of soil-breaking rotary tillage.

[0024] In this embodiment, the horizontal projections of the heel portion 31 and the blade body portion 32 are straight lines; the bending directions of the horizontal projections of the first blade edge 331 and the second blade edge 332 are symmetrically distributed with respect to the blade body portion 32. Specifically, the heel portion 31 and the blade body portion 32 are designed to be straight, and combined with the symmetrical double-edged design, the blades do not need to be distinguished between left and right blade types when installed in the cutting tool. The symmetrical blades ensure consistent force and angle when throwing soil, reducing the user's operational and installation threshold, lowering production, processing, packaging, and transportation costs for manufacturers and sellers, and improving overall usage efficiency.

[0025] In this embodiment, the blade height a of the first blade 331 and the blade height b of the second blade 332 are both 63mm; the total length of the heel portion 31, the blade body portion 32 and the blade edge portion 33 is 255mm.

[0026] Example 2, reference Figures 4-5 In this embodiment, the only difference is that the horizontal projections of the blade heel portion 31 and the blade body portion 32 are in a straight line; the bending direction of the horizontal projection of the second blade 332 is perpendicular to the blade body portion 32.

[0027] refer to Figures 1-12 This utility model also provides a micro-tiller blade, which is equipped with the micro-tiller blades 3 of the above embodiments one and two, and the micro-tiller blades 3 are detachably mounted on the mounting plate 2.

[0028] In practical use, different lengths of main shaft 1 and corresponding numbers of mounting discs 2 can be selected according to the actual terrain and the model of the tiller to adapt to different usage scenarios.

[0029] This mini-tiller's basic components consist only of a main shaft 1, a mounting plate 2, and mini-tiller blades 3. The overall structure is simple, lighter, and stronger. The mini-tiller blades 3 are bolted to the mounting plate. The blades, featuring a double-edged structure, avoid multiple welding operations, reducing processing and turnover costs. Furthermore, the one-piece molding structure reduces the number of parts while increasing structural strength. The double-edged blade design eliminates the need to distinguish between left and right sides, reducing the user's operational and installation barriers and lowering production, processing, packaging, and transportation costs for manufacturers and sellers. In practical use, it improves soil breaking efficiency, reduces soil clods, increases weed breaking efficiency in wasteland, and reduces weed entanglement. During tillage, the double blades counteract the lateral forces exerted by the soil on the blades, significantly reducing blade and blade vibration during operation, improving overall blade stability, extending service life, and ultimately reducing working time and increasing tillage efficiency.

[0030] Specifically, the shape and quantity of the installation disc 2 can be varied according to requirements; Preferably, the mounting disc 2 is rectangular, and there are six of them. Multiple mounting discs 2 are installed coaxially. The blades 3 are screwed onto the mounting discs 2 using mounting holes 312, and each mounting disc 2 is equipped with two blades 3, forming a double-blade, six-group cutting tool.

[0031] Preferably, the vertical projection of the mounting disc 2 is a triangle, and there are four of them. Each side can be equipped with a blade 3 to form a three-piece, four-group type of blade. The multi-piece mounting structure is suitable for high-speed scenarios, which facilitates more efficient weeding and clearing, as well as the need for cultivating smaller soil clods, further expanding the application range of the blade.

[0032] In this embodiment, the tool holder 30 is provided with a clearance groove 311 for avoiding the spindle 1. Specifically, the tool heel portion 31 in the tool holder 30 is provided with a clearance groove 311 to facilitate avoiding the spindle 1 and to achieve a certain degree of weight reduction.

[0033] In this embodiment, the installation distance h between two adjacent mounting discs 2 is no greater than the sum of the blade height a of the first blade 331 and the blade height b of the second blade 332. Specifically, since the blade 3 has a double-edged bent design, the projection plane of the first blade 331 and the second blade 332 between the two different blades 3 is the projection of the tillage position. When a+b≤h, it means that the soil between adjacent mounting discs 2 has not been missed, thereby improving the overall tillage efficiency and reducing the operation time.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
