Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and more specifically, to a hand-push soil loosening machine. Background Technology

[0002] A soil tiller is a type of machinery commonly used in agricultural operations. Its main function is to loosen the soil, improve soil structure, enhance soil aeration and water retention, and promote plant growth. There are many types of soil tillers, the most common being rotary tillers, disc tillers, and chain tillers. Using soil tillers can improve soil quality and increase crop yields, making them an indispensable piece of equipment in modern agricultural production.

[0003] The soil tiller mainly consists of an engine, a reduction gear, and a walking mechanism. The electric motor provides power and is connected to the reduction gear shaft through a coupling, thereby driving the reduction gear shaft to rotate. The reduction gear shaft drives the rotation of the tiller blades to turn over the soil. However, there may be large stones in the soil. When the tiller blades come into contact with these stones, it will not only cause the soil tiller to jam, but also cause the tiller blades to be chipped or broken, thus greatly reducing the service life of the soil tiller.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a hand-push soil ripper to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hand-push type soil tiller, including a frame, on which a moving wheel, a reduction gear shaft and an engine for driving the reduction gear shaft to rotate are mounted, a soil tiller blade is mounted on the reduction gear shaft, a bulldozing rake is mounted on the lower surface of the frame, the soil tiller blade is located between the bulldozing rake and the moving wheel, the bulldozing rake includes a support frame and a plurality of teeth, the front end of the teeth being conical.

[0007] By adopting the above technical solution, when the soil loosening machine is working, the bulldozing rake located in front of the loosening blades can push larger stones forward or arch them upward, thereby preventing the loosening blades from touching these stones, greatly increasing the service life of the loosening blades, making the loosening blades run more smoothly, and the bulldozing rake can also play a preliminary role in loosening the soil. The loosening blades rotate under the drive of the engine, further turning the soil up and down, thereby improving the soil structure and promoting plant growth.

[0008] The present invention is further configured such that: a column is fixedly connected to the upper end of the tooth, a plurality of circular holes penetrating the support frame are provided on the support frame, and a nut is threadedly connected to one end of the column that passes through the circular holes.

[0009] By adopting the above technical solution, the teeth and support frame are fixedly installed by connecting the column and nut with threads, which makes the installation simple and convenient. Because multiple round holes are provided, the operator can rotate and connect different numbers and different spacings of teeth according to the actual situation, making the bulldozer rake suitable for different scenarios.

[0010] The present invention is further configured such that: the support frame is provided with a square groove communicating with the round hole, and a square block that engages with the square groove is fixedly connected to the column.

[0011] By adopting the above technical solution, the square block and the square groove are engaged to prevent the teeth from rotating circumferentially within the support frame, thus enabling stable operation.

[0012] The present invention is further configured such that a spring washer fitted on the column is provided between the nut and the support frame.

[0013] By adopting the above technical solution, the spring washer ensures that there will be no slippage between the nut and the column when they are rotated together, making the connection more secure.

[0014] The present invention is further configured such that: the tooth includes a connecting section and a breaking section, the cross-section of the connecting section is triangular, and the breaking section is conical.

[0015] By adopting the above technical solutions, both the triangular connecting section and the conical breaking section can reduce the force-bearing area between the teeth and the soil, thereby increasing the pressure between the teeth and the soil, and thus making it easier to achieve the purpose of breaking the soil.

[0016] The present invention is further configured such that: the soil loosening tool includes a cutter ring arrayed on the reduction gear shaft, and a circumferential array of blades is fixedly connected to the cutter ring.

[0017] By adopting the above technical solution, the front end of the blade is provided with a bend, so that when the blade rotates, it can drive the soil to turn up and down, thereby achieving the purpose of better loosening the soil.

[0018] The present invention is further provided that a dustproof plate is fixedly connected to the frame.

[0019] By adopting the above technical solution, the dustproof plate can block the soil turned up when the soil tamper rotates, preventing a large amount of soil from splashing backward and affecting the workers.

[0020] The present invention is further configured such that the loosening blades and the bulldozing rakes are both made of stainless steel.

[0021] By adopting the above technical solutions and utilizing the excellent corrosion resistance and high strength of stainless steel, the soil loosening tools and the pusher rakes have a long service life.

[0022] In summary, this utility model has the following beneficial effects:

[0023] When the soil tiller is working, the bulldozing rake located in front of the tiller blades can push larger stones forward or arch them upward, thus preventing the tiller blades from touching these stones, greatly increasing the service life of the tiller blades and making the tiller blades run more smoothly. In addition, the bulldozing rake can also play a preliminary role in loosening the soil. The tiller blades rotate under the drive of the engine, further turning the soil up and down, thereby improving the soil structure and promoting plant growth. Attached Figure Description
