Ecological restoration device for sand and gravel plants

Abstract

The invention discloses an ecological restoration device for sand and gravel plants. The ecological restoration device comprises a sand and gravel soil treatment chamber and a vegetation recovery chamber, wherein crushing rolls, a mixing cylinder and a soil improvement substrate storage chamber are arranged in the sand and gravel soil treatment chamber; a horizontal stirring shaft is arranged in the mixing cylinder along a central axis; screw blades are arranged on the stirring shaft; one side of the vegetation recovery chamber and the sand and gravel soil treatment chamber are welded into a whole, and the top end of the other side of the vegetation recovery chamber is connected with a bucket; a row of metal teeth is formed in the front end of the bucket; column holes are formed in the metal teeth; an expansion bit is arranged in the column holes; a soil turning and impurity removing device and an irrigating and sowing device are arranged in the vegetation recovery chamber; the soil turning and impurity removing device comprises a long rotating shaft and multiple rows of hooked teeth arranged on the long rotating shaft; the irrigating and sowing device comprises a seed storage chamber and an irrigation chamber; multiple rows of seed spreading devices are arranged on the outer side of the seed storage chamber; and multiple rows of sprinkler heads are arranged on the outer side of the irrigation chamber. The invention aims to fundamentally solve the problems such as too much sand and gravel in aggregate storage soil, hardening, poor water-holding capacity and low nutrient, sothat the sand and gravel plants restore the original ecological system.

Description

technical field [0001] The invention relates to the technical field of sand and gravel quarry restoration, and more specifically, relates to an ecological restoration device for a sand and gravel quarry. Background technique [0002] As a kind of abandoned land, the sand and gravel yard not only occupies a large amount of land, but also destroys a large area of ​​vegetation and the original ecosystem, forming extreme habitat conditions, resulting in the disappearance of a large number of species, a sharp decline in biodiversity, and the ecosystem However, there are more sand and gravel in the sand and gravel quarry, which can easily cause the soil to compact and cause difficulties for secondary development and utilization. Therefore, the ecological restoration of sand and gravel quarries has become one of the current research hotspots. [0003] In the ecological restoration of sand and gravel quarries, soil matrix improvement is the first and core problem that needs to be s...
