Comprehensive improvement device for saline-alkali land

Abstract

The invention discloses a comprehensive improvement device for saline-alkali land. The device comprises a rack, a topsoil extraction mechanism, a topsoil backfilling mechanism, a spreading material adding mechanism and a pressing mechanism, wherein the topsoil extraction mechanism comprises a shovel plate arranged on the front side of the rack and a soil conveying device arranged on the rack and connected to the rear side of the shovel plate; the topsoil backfilling mechanism comprises a sieve plate arranged on the rack and connected to the rear side of the soil conveying device; the spreadingmaterial adding mechanism comprises a storage bin arranged on the rack and located above the sieve plate and a discharge box arranged on the rack and located on the lower side of the sieve plate; thestorage bin and the discharge box are arranged at an interval vertically and communicated through a plurality of pipes; the pressing mechanism comprises a first pressing roller, a second pressing roller and a third pressing roller, the first pressing roller and the second pressing roller are arranged on the rack and located on the front side and the rear side of a discharge opening of the discharge box, the third pressing roller is arranged on the rack and located on the rear side of the sieve plate, the first pressing roller is located below the soil conveying device, and the second pressingroller is located on the front side of the sieve plate below the discharge box. The device has high automation degree, and can quickly and efficiently finish saline-alkali land reconstruction work.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to a comprehensive improvement device for saline-alkali land. Background technique [0002] There are many ways to improve saline-alkali land, among which the main process of saline-alkali land improvement is: first use agricultural equipment to collect the topsoil in the planting area and stack it in a designated place, then spread the improved additives evenly, then backfill the topsoil, and finally Compact the soil in the improvement area; each step of the soil improvement operation needs to be completed with a separate equipment, which has a low degree of automation and reduces the construction efficiency of the improvement; at the same time, the collection and stacking of the surface soil also increase the difficulty of construction, which is not conducive to Rapid and efficient completion of saline-alkali land transformation.
