Saline-alkali soil reclamation machine

Abstract

The invention discloses a saline-alkali soil reclamation machine. The saline-alkali soil reclamation machine comprises an arched chassis, wherein an installation perching knife is in seamless connection with the front of the chassis, side walls are fixedly connected with the left and the right sides of the chassis and stretches upwards in accordance with the shape of the side edges of the chassis, the front end of each of the side walls extends forwards to two sides of the perching knife, two plowshares are fixedly connected at the left end and the right end of the head of the perching knife, a membrane winding up roller is arranged below the chassis, a ladder-shaped model is fixed behind the side walls, the ladder-shaped model consists of two side panels and an upper panel and presents the shape of a ladder which is narrow at the upper part and wide at the lower part seen from the marching direction of a vehicle, and a pair of front wheels and a pair of rear wheels are installed at the outside of the side walls. The saline-alkali soil reclamation machine is used for mechanized exploitation and utilization of the saline-alkali soil, is a novel facility which exploits and utilizes the saline-alkali soil for agricultural production economically, efficiently and in large scale, can effectively solve the problem of accumulation of salts in the surface soil, and saves water resources greatly; compared with the customary mode in which a large amount of water is used for weakening alkali to reform the saline-alkali soil, the saline-alkali soil reclamation machine is time-saving, is water-saving, does not bring the accumulation of salts in the surface soil and has good effect.

Description

technical field [0001] The invention belongs to the field of cultivated land reclamation machinery and equipment, and in particular relates to a saline-alkali land reclamation machine. Background technique [0002] The improvement method of saline-alkali land is usually to irrigate and leaching with a large amount of fresh water, which is the so-called "big water pressure alkali". This method needs to consume a lot of water resources; moreover, the saline-alkali substances will continue to rise with the evaporation and transpiration of water, and the phenomenon of "returning to alkali" will appear. Preventing the recovery of underground saline-alkali substances is an effective measure to improve saline-alkali land. The usual practice is to spread a layer of membrane on the saline-alkali soil, build a cultivation ridge on the membrane, and then leaching the cultivation ridge with water to remove alkali. After the alkali is discharged, the soil above the membrane will not "re...
