Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to an anti-collision protection mechanism for agricultural machinery. Background Technology
[0002] Agricultural machinery refers to all kinds of machinery used in crop cultivation and animal husbandry, as well as in the initial processing and handling of agricultural and livestock products. Agricultural machinery comes in many varieties, including but not limited to agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, livestock machinery, and agricultural transportation machinery. Agricultural machinery requires anti-collision protection mechanisms during use. The existing publication number CN220662467U discloses an agricultural machinery anti-collision protection mechanism. This mechanism uses a collision plate composed of a crossbeam and an arc-shaped plate, along with a rotating elastic buffer combination of a collision pipe and a collision rod, to provide collision protection at different angles of the agricultural machinery body, effectively improving the anti-collision effect. It can also provide further buffer protection for agricultural machinery in non-head-on collisions, enhancing the anti-collision buffer protection function. However, this anti-collision protection mechanism cannot increase the friction between the agricultural machinery and the ground, resulting in poor stability when the agricultural machinery is impacted, which can easily cause slippage and rollover, bringing certain adverse effects to actual use. Therefore, improvements are needed. Utility Model Content

The slider 14 and the slide groove 15 are slidably connected and adapted to each other, so that the toothed plate 7 can move stably under the sliding action of the slider 14 and the slide groove 15.
[0021] Furthermore, a limiting frame 16 is fixedly installed on the right side of the connecting plate 5. An L-shaped insert 17 is provided inside the limiting frame 16. The other side of the L-shaped insert 17 is fixedly connected to the anti-collision plate 6. The setting of the limiting frame 16 and the L-shaped insert 17 facilitates the quick replacement of the anti-collision plate 6 by the staff.
[0022] Example 2, please refer to Figures 1 to 4 The difference between this embodiment and embodiment 1 is that: a spring 18 is fixedly installed on the left end of the anti-collision bar 4, and the other end of the spring 18 is fixedly connected to the left side of the inner wall of the box 2.
