Description

Technical Field

[0001] The present application relates to the technical field of hoisting machines, and more specifically, to an agricultural machinery hoisting machine. Background Art

[0002] Agricultural machinery refers to various machines used in the crop planting and animal husbandry production processes, as well as in the primary processing and treatment of agricultural and animal products; agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilizing machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transport machinery, etc. Since agricultural machinery is relatively heavy, in the existing technology, during the use of the hoisting machine, the load on the hoisted objects is unstable, and the shaking during the hoisting may cause the objects to fall off, posing a certain safety hazard to the people nearby. The shaking will also cause the rope to wear, greatly reducing the life of the rope, and even leading to the breakage of the rope.

[0003] The document with prior art publication number CN 213771040 U provides an agricultural machinery hoisting device. The device inserts a pin column in a hook mechanism into a column groove to prevent objects from falling off due to shaking during the hoisting process. After the pin column is inserted, such problems are effectively avoided. The rope for hoisting objects is engaged by the buffer groove, and the rubber sleeve is put into the rope to prevent the hoisting rope from rubbing back and forth, which may accelerate the loss of the rope's life.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: after the cargo is hoisted, the device can only lift the cargo, and when the hoisted cargo is rotated, it will cause the problem of inconvenience in rotating the cargo.

[0005] In view of this, we propose an agricultural machinery lifting machine. Utility Model Content

When the cargo needs to be hoisted, the base 1 is adjusted to an X-shaped state to increase the support area of ​​the base 1, so that four V-shaped support states are formed in the X state of the base 1. Then, the cargo is hung by the hook 8, and the boom 7 is supported by the extension of the hydraulic cylinder 6 so that the cargo is lifted. Then, the rotating pillar 2 is rotated on the base 1. At this time, the stability of the rotating pillar 2 is improved on the base 1 in the X-shaped state to avoid the problem of overall tipping. At the same time, the base 1 can be lifted by adjusting the supporting legs 3 to avoid the movement of the base 1 caused by the rolling of the universal wheels 5 at the bottom of the base 1.

[0032] The base 1 includes a first leg 11 and a second leg 12.

At this time, the base 1 is in an X-shaped state as a whole.
