A hoisting device for maintenance of agricultural machinery and equipment

Abstract

The invention discloses a hoisting device for maintenance of agricultural machinery equipment. The hoisting device comprises two side plates and two bottom plates, wherein four screw rod shafts are respectively arranged between the two bottom plates and a top plate. Sliding sleeves which are in threaded fit connection with the four screw rod shafts are arranged on the four screw rod shafts, hoisting discs are arranged between the four sliding sleeves, hoisting mechanisms are arranged on the hoisting discs, a hoisting motor is arranged on the top plate, and the hoisting motor is connected withthe shaft sections of the two screw rod shafts on the two sides through transmission mechanisms, transmission belt wheels are further arranged on the shaft sections of the four screw rods, and the twodriving belt wheels on the same side are also connected through transmission belts. The hoisting device is simple in structure, stable in hoisting structure, simple and convenient to operate, wide inapplication wide and high in practicability, and can be adapted to hoisting of instruments with different sizes.

[0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products; agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and Fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc.; in a broad sense, agricultural machinery also includes forestry machinery, fishery machinery, sericulture, beekeeping, edible fungus cultivation, etc. Rural sideline machinery; agricultural machinery is a relative concept, referring to the general term for all machinery used in agriculture, animal husbandry, forestry and fishery. Agricultural machinery belongs to the category of agricultural machinery; the promotion and use of agricultural machinery is called agricultural mechanization; the current agricultural machinery maintenance is generally It is necessary for maintenance personnel to climb or drill into the lower end of the equipment for maintenance. It is extremely inconvenient to work during maintenance and the safety of maintenance personnel is not guaranteed. It is difficult to hoist stably with ordinary hoisting tools, and unstable hoisting is likely to cause greater danger. For hoists that cannot accommodate different sizes and shapes
