Description

Technical Field

[0001] This utility model relates to the field of micro-tiller technology, and in particular to a micro-tiller drive wheel. Background Technology

[0002] A mini tiller is a small, lightweight agricultural machine suitable for rotary tilling, ditching, and weeding in orchards, greenhouses, or small plots of land. Powered by gasoline or diesel, it is easy to operate and can replace traditional ox-drawn plows or manual labor, improving farming efficiency. Mini tillers move by pushing their wheels. Current mini tillers typically require adjustment via iron wheels and resistance rods to ensure normal operation, but this method offers poor control and cannot meet the demands of tilling. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a drive wheel for a micro-tiller.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A micro-tiller drive wheel includes: a rod body; two discs symmetrically fixed to the rod body; several connecting members fixed to the two disc surfaces; and blades detachably connected to grooves in the connecting members.

[0006] Furthermore, the blade includes a socket section, a transition section, and an insertion section; the socket section is fixedly connected to the insertion section through the transition section, and the three are integrally formed.

[0007] Furthermore, the end of the insertion segment furthest from the transition segment is integrally formed with a pointed tip.

[0008] Furthermore, the wide face of the socket segment is perpendicular to the wide face of the insertion segment.

[0009] Furthermore, the connector is provided in five parts, two of which are fixed to one side of the disc body and the other three are fixed to the other side of the disc body.

[0010] Furthermore, the disc body is circular in shape; the distribution of the five connectors, projected along the length of the rod body, forms an evenly distributed disc body.

[0011] Furthermore, the three connectors located on the other side of the disc are arranged in a Y-shape.

[0012] Furthermore, the connector and the blade can be fastened by at least one pair of bolts and nuts.

[0013] The beneficial effects of this utility model are:

[0014] (1) By setting the wide face of the blade's socket section to be perpendicular to the wide face of the insertion section, the push wheel can form a continuous and uniform tillage layer during tillage, which makes it more effective for the push wheel to be inserted into and removed from the soil to move forward, thereby improving work efficiency.

[0015] (2) Compared with the traditional method of adjusting the iron wheel and resistance bar, the tool itself can generate both driving force and resistance, and is easy to disassemble, and can adapt to different types of land. Attached Figure Description

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Reference Figure 1-3 As shown, a mini-tiller drive wheel includes: a rod body 1; two disc bodies 2, symmetrically fixed to the rod body 1; several connecting members 3, fixed to the two disc surfaces of the disc body 2; and blades 4, detachably connected to a groove 31 in the connecting member 3. The connecting member 3 and the blades 4 can be fastened together by at least one pair of bolts and nuts.

[0024] It should be noted that the rod 1 has a slender structure and is preferably made of high-strength alloy steel. Mounting holes (not shown) may be provided at both ends of the rod 1 for connection to the power output shaft of the micro-tiller. The cross-sectional shape of the rod 1 can be circular, rectangular, or other polygonal. The surface of the rod 1 can be treated with rust prevention, such as galvanizing or spraying with rust-preventive paint, to improve its durability. The disc 2 is preferably fixedly connected to the rod 1 by welding, but riveting, threaded connection, or other mechanical connection methods can also be used. The disc 2 is circular in shape, and its diameter can be determined according to actual working needs, for example, between 200mm and 500mm. The thickness of the disc 2 is preferably between 10mm and 20mm to ensure sufficient strength and rigidity. The material of the disc 2 can be the same as that of the rod 1, preferably high-strength alloy steel, to ensure its reliability during operation. The connecting piece 3 is fixedly connected to the two disc surfaces of the disc 2. The connecting piece 3 is preferably fixedly connected to the disc 2 by welding, but other mechanical connection methods can also be used. The connector 3 has a groove 31 for accommodating the sleeve section 41 of the blade 4. The shape of the groove 31 matches the shape of the sleeve section 41, preferably a rectangular groove, with a width slightly larger than the width of the sleeve section 41 to facilitate the installation and adjustment of the blade 4. The depth of the groove 31 can be determined according to the length of the sleeve section 41, preferably 1 / 2 to 2 / 3 of the length of the sleeve section 41, to ensure a secure fixation of the blade 4. The bolts are preferably made of high-strength stainless steel to prevent corrosion and damage. The number of bolts can be determined according to the size of the blade 4 and the working load, preferably at least one, more preferably two or more, to provide a more reliable fixation. The tightening torque of the bolts can be adjusted as needed to ensure that the blade 4 does not loosen during operation. The diameter and length of the bolts can be determined according to the dimensions of the connector 3 and the blade 4, preferably M8 to M12. The bolts can be tightened using ordinary nuts or self-locking nuts. In this application, the disc body 2, connector 3, and blade 4 together form a disc-type structure, which facilitates insertion into and removal from the soil, allowing the micro-tiller to move forward as a whole.

[0025] Specifically, the blade 4 includes a connecting section 41, a transition section 42, and an insertion section 43; the connecting section 41 is fixedly connected to the insertion section 43 via the transition section 42, and the three are integrally formed. The blade 4 is preferably made of high-strength alloy steel through forging or stamping processes to ensure its overall strength and durability. The connecting section 41 has a rectangular cross-sectional shape, and its width and thickness can be determined according to the dimensions of the groove 31 of the connector 3. The transition section 42 is arc-shaped or oblique, used to connect the connecting section 41 and the insertion section 43; its arc or angle can be determined according to working requirements, preferably between 30° and 60°. The insertion section 43 is the working part of the blade 4, and its shape is flat, preferably with sharp edges to facilitate insertion into the soil and propel the tiller forward.

[0026] Specifically, the end of the insertion section 43 furthest from the transition section 42 is integrally formed with a tip 44. The tip 44 is sharp, preferably triangular or conical, to facilitate insertion into the soil and reduce tillage resistance. The sharpness of the tip 44 can be determined according to the working requirements, preferably between 30° and 60°.

[0027] Specifically, the wide face of the socket section 41 is perpendicular to the wide face of the insertion section 43. This design allows the blade 4 to more effectively insert into the broken soil during operation and also allows the entire push wheel to be smoothly removed from the soil to continue moving forward, improving work efficiency. The width ratio of the socket section 41 and the insertion section 43 can be determined according to work requirements, preferably between 1:1.5 and 1:2.5.

[0028] Specifically, there are five connectors 3, two of which are fixed to one side of the disc 2, and the other three are fixed to the other side of the disc 2. The distribution of the connectors 3, projected along the length of the rod 1, evenly divides the disc 2, meaning the five connectors 3 are evenly distributed on the circumference, with an angle of 72° between adjacent connectors 3. This distribution ensures that the blade 4 is subjected to uniform force during operation, improving work stability and efficiency. Furthermore, the two-sided distribution allows for balanced rotation. In this application, the connectors 3 use a sleeve-type housing to ensure the blade is fixed in place.

[0029] Specifically, the disc 2 is circular in shape; the distribution of the five connectors 3 is projected onto the length of the rod 1 so as to evenly divide the disc 2.

[0030] Specifically, the three connectors 3 located on the other side of the disc 2 are arranged in a Y-shape. That is, two of the three connectors 3 are located on one side of the disc 2, and the other is located on the opposite side, forming a Y-shaped layout. This arrangement allows the blade 4 to more effectively cover the working area during operation, reducing omissions.

[0031] In a preferred embodiment, the diameter of the disc body 2 is 300 mm and the thickness is 15 mm. The width of the groove 31 of the connector 3 is 20 mm and the depth is 30 mm. The width of the socket section 41 of the blade 4 is 18 mm and the thickness is 10 mm; the width of the insertion section 43 is 40 mm and the thickness is 5 mm; the curvature of the transition section 42 is 45°. The sharpness of the tip 44 is 45°. The bolts are M10 stainless steel bolts, and the tightening torque is 50 N·m.

[0032] In another embodiment, the shape of the disc 2 can be changed to a polygon, such as a hexagon or an octagon, to adapt to different working requirements. The number and distribution of the connectors 3 can also be adjusted as needed; for example, six connectors 3 can be provided, three on each side, evenly distributed.

[0033] This application applies to four-wheel drive mini-tillers or ride-on mini-tillers.

[0034] The working principle of this utility model:

[0035] When the mini tiller is working, power is transmitted to the lever 1 through the output shaft, driving the entire push wheel to rotate. During rotation, the tip 44 of the blade 4 first pierces the soil, followed by the insertion section 43, which then inserts into the soil and propels the mini tiller forward. Because the wide face of the sleeve section 41 of the blade 4 is perpendicular to the wide face of the insertion section 43, the push wheel can form a continuous and uniform tillage layer during tillage, making it more efficient for the entire push wheel to insert into and move out of the soil, thus improving work efficiency.

[0036] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
