Description

Technical Field

[0001] This utility model belongs to the field of agricultural technology, and more specifically, it relates to an agricultural rotary tiller. Background Technology

[0002] An agricultural rotary tiller is an agricultural machine used for soil cultivation. It loosens, breaks up, and mixes the soil through rotating blades. It is suitable for soil preparation before sowing, improving soil permeability, soil structure, and tillage efficiency.

[0003] Currently, when some agricultural rotary tillers are used for tilling, weeds easily get tangled on the cutter rollers. Once too many weeds are tangled on the cutter rollers, the tilling effect of the rotary tillers will be significantly affected. The commonly used methods to deal with this are to disassemble the rotary tillers or lift the frame. The operator has to crawl under the frame and cut the weeds one by one with the blades. This operation is time-consuming and laborious, which seriously reduces work efficiency.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an agricultural rotary tiller with greater practical value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an agricultural rotary tiller, which is achieved by the following specific technical means: An agricultural rotary tiller includes a frame, within which a cutter roller is installed. A plurality of rotary tillers are bolted to the periphery of the cutter roller, with equal spacing between any two adjacent rotary tillers. The cutter roller has an internal cavity, and its surface has a plurality of through grooves between any two adjacent rotary tillers. A mounting rod is movably connected within the cavity. A cutting blade is mounted on the periphery of the mounting rod at each of the through grooves, with blades on both sides extending beyond the through grooves. One end of the mounting rod has a threaded groove, within which a threaded rod is threadedly connected, and a rotating rod is mounted on one end of the threaded rod.

[0006] Furthermore, the length of the cavity is greater than the length of the mounting rod.

[0007] Furthermore, the outer diameter of the rotating rod matches the inner diameter of the cavity.

[0008] Furthermore, a limit block is installed at one end of the threaded rod within the threaded groove.

[0009] Furthermore, one end of the rotating rod extends to the outside of the frame.

[0010] Furthermore, a rotating block is installed at one end of the rotating rod that extends outside the frame.

[0011] Furthermore, the surface of the rotating block is provided with an anti-slip texture.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By using a combination of a rotating block, a rotating rod, a threaded rod, a mounting rod, and cutting blades, after the rotary tiller has been tilling the land for a period of time, when some weeds become entangled on the cutter shaft roller, the operator begins to rotate the rotating block. The rotating block drives the threaded rod to rotate via the rotating rod, and the rotation of the threaded rod in turn drives the mounting rod to move. The mounting rod then drives several cutting blades to move. During this process, the cutting blades can cut off the weeds entangled on the cutter shaft roller, causing them to fall off. This process saves time and effort and improves work efficiency. Attached Figure Description
