Overlying sand righting and compacting device for shrub planting

Abstract

The invention discloses an overlying sand righting and compacting device for shrub planting. The overlying sand righting and compacting device comprises a top end disc support, a linear driving mechanism, a plurality of hinge four-bar mechanisms, a plurality of arc-shaped circular plates, a plurality of gear and rack transmission mechanisms and a plurality of righting rods. The hinge four-bar mechanisms are distributed below the top end disc support in an annular array mode, and the arc-shaped circular plates are arranged on the hinge four-bar mechanisms. The linear driving mechanism is used for driving the hinge four-bar mechanism to contract, so that the plurality of arc-shaped circular plates contract and are spliced into a cylindrical shape, and sandy soil around the shrub seedlings is gathered into the hole; a gear rack transmission mechanism and a pair of righting rods are arranged on the inner side of the arc-shaped circular plate, the gear rack transmission mechanism is connected with a hinge four-bar mechanism, and the hinge four-bar mechanism shrinks to drive a gear to rotate, so that the plurality of groups of righting rods get close to each other, and the righting operation of shrub seedlings is completed. According to the device, the integrated work of sand covering, righting and compacting of desert shrubs can be synchronously carried out, the planting efficiency can be improved, and the labor amount is reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a sand-covered righting and compacting device for shrub planting. Background technique [0002] my country's desert and desertified land area is about 1.607 million square kilometers, accounting for 16.7% of the country's land area, and it is one of the countries with the most severe desertification in the world. [0003] Seabuckthorn is a deciduous shrub that is resistant to drought and wind and sand. It can survive in salinized land and is widely used for water and soil conservation. Seabuckthorn is widely planted in Northwest China for desert greening. [0004] The Haloxylon tree can grow and reproduce in deserts with harsh natural conditions, and spreads rapidly into patches. It is light-loving, resistant to high temperature and severe cold, adapts to atmospheric drought and soil drought, and can survive on desert soil in areas with an annual precipitation ...

AI Technical Summary

Problems solved by technology

[0006] Because the planting of shrubs is relatively complicated, there is currently no planting device specifically for desert shrubs. It mainly performs a series of complex operations such as drilling holes, feeding seedlings, throwing seedlings, covering sand, and irrigating manually, which requires a large amount of labor and low planting efficiency.
