Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery support bases, in particular to an anti-skid enhanced small agricultural machinery support base. Background Art

[0002] The anti-skid enhanced small agricultural machinery support base is a base designed to support and stabilize small agricultural machinery. It is characterized by anti-skid and enhanced stability. This base is usually used to improve the stability and safety of agricultural machinery during work and prevent accidental movement or tipping of agricultural machinery due to slippery ground or other factors.

[0003] A Chinese patent with publication number CN215348118U discloses a shelf for unmanned convenience stores, including a base, a counterweight block fixedly connected to the bottom of the base, and universal wheels fixedly connected to both sides of the bottom of the base. The base, the counterweight block, the universal wheel, the bottom plate, the limit rod, the top frame, the camera, the limit device, the suspension device and the support device form a whole, which is easy to move. A counterweight block is arranged at the bottom of the base to lower the overall center of gravity and improve the overall stability.

[0004] During actual use, the shelf of the above patent is supported by the universal wheels that contact the ground. The movement of the bracket can be restricted only by stopping the rotation of the universal wheels. However, simply restricting the rotation of the universal wheels to fix the bracket can easily cause the bracket to shift in position after being impacted. When the base of the bracket is placed in a smooth position, the anti-slip ability is weak. Utility Model Content

[0038] Working principle: when the bracket is in use, the universal wheel 8 is used as a support and the bracket and the base frame 1 are driven to move after the universal wheel 8 rotates. After moving to the corresponding position, the motor 2 is started, and the output shaft of the motor 2 can drive the transmission threaded rod 9 to rotate. The rotation of the transmission threaded rod 9 can generate relative movement with the first transmission piece 7. After the first transmission piece 7 is restricted by the restriction rod 10, the rotational movement is converted into longitudinal linear movement. The longitudinal linear movement can store the universal wheel 8 inside the base frame 1. At the same time, the first transmission piece 7 will drive the first transmission tooth groove 13 to move longitudinally through the second transmission piece 12. The longitudinal movement of the first transmission tooth groove 13 can be driven by the transmission gear 14. The third transmission plate 15 with the second transmission tooth groove 17 is moved, and the third transmission plate 15 moves longitudinally downward to push the second suction cup 11, so that the second suction cup 11 is placed toward the bracket, and the bracket is fixed by the adsorption of the second suction cup 11. When the external impact causes the base frame 1 to shake and move toward one end, the external impact will cause the rubber pad 3 to move in the active cavity 4, move and contact the press sensor 5, and the press sensor 5 will give the nearest vacuum air pump 19 a start signal. The start of the vacuum air pump 19 can extract the gas at one end of the first suction cup 6, and assist the adsorption of the second suction cup 11 through the first suction cup 6. The anti-slip ability of the bracket as a whole is improved through adsorption.
