Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a tillage plow for agricultural machinery. Background Technology

[0002] A plow is an agricultural implement for tilling the land. It consists of a heavy blade at the end of a crossbeam and is usually attached to a group of animals or motor vehicles that pull it. It can also be driven by human power. It is used to break up clods of soil and create furrows to prepare for sowing. There are several types of plows, including moldboard plows, disc plows, and rotary plows. When tilling the land, agricultural machinery is needed, and in tilling the land, agricultural plows are required.

[0003] Existing agricultural machinery typically uses fixed plows, which are difficult to disassemble and inconvenient to use when the plowshare needs to be replaced according to soil texture. Existing technology has proposed a plow for agricultural machinery, as disclosed in Chinese Patent [Application No. CN202221249152.1], which includes a connecting frame and a fixed sleeve set on the connecting frame. The fixed sleeve has an adjusting rod inside, a first fixing plate on one side of the adjusting rod, an mounting rod on the first fixing plate, and a plowshare body on the mounting rod. This utility model comprises a fixed sleeve, an adjusting rod, a first fixing plate, an mounting rod, and a plowshare body. Although this patent allows the plowshare body to be disassembled and replaced after the mounting rod is no longer locked in place, by pushing the first push rod to disengage the fixing block from the first and second locking teeth, making the disassembly process simple, quick, and convenient, the patent has certain drawbacks in its use. For example, in actual farming, different crops are planted on different plots of land, and the spacing between the plowshares needs to be adjusted accordingly. The patent cannot adjust the distance between the plow blades for different crops. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tillage plow for agricultural machinery.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tillage plow for agricultural machinery includes a connecting frame, a mounting column fixedly connected to one side of the connecting frame, a connecting plate fixedly connected to one side of the mounting column, a limiting plate fixedly connected to one side of the connecting plate, multiple sets of limiting frames slidably connected to the outer surface of the limiting plate, a threaded hole opened at the top of the limiting frame, a fixing bolt threaded into the inside of the threaded hole, and a plow blade fixedly connected to the bottom of the limiting frame.

[0007] Preferably, the top of the limiting plate is provided with a placement groove, and multiple sets of slots are evenly provided on the bottom side of the placement groove. Two sets of springs are fixedly connected to the top side of the inner side of the limiting frame. A positioning plate is fixedly connected to the bottom of the spring. A corresponding slot is fixedly connected to the bottom of the positioning plate. The bottom of the fixing bolt abuts against the positioning plate.

[0009] Preferably, one side of the limiting frame is provided with a through groove that can accommodate the connecting plate.

[0010] The beneficial effects of this utility model are as follows: When using the agricultural plow provided by this utility model, if it is necessary to adjust the distance between the plow blades, the limiting frame on the limiting plate can be moved to drive the plow blades to move, thereby adjusting the distance between multiple sets of plow blades. After adjustment, the fixing bolt can be turned to push the positioning plate, and then the card plate under the positioning plate can be inserted into the card slot, so that the plow blades on the limiting frame no longer move. It can be adjusted according to the soil where different crops are planted. By setting up the card slot and card plate, the sliding of the limiting frame can be better prevented. When it is necessary to disassemble the plow blades, the fixing bolt can be turned to make them no longer in contact with the positioning plate, and the limiting frame can be moved to separate from the limiting plate, thus completing the disassembly of the plow blades.
