Desert land reclamation device

Abstract

The invention relates to a desert land reclamation device, which comprises two transporting mechanisms in bilateral symmetry. Each transporting mechanism has functions of advancing, backing and on-the-spot turning and comprises a body, two supporting parts are arranged at the upper end of each body, four driving wheels are symmetrically arranged at the bottom of each body, a U-shaped connection beam is arranged at upper ends of every two supporting parts, a connection crossbeam is penetratingly arranged between the two U-shaped connection beams through slide fit, and the upper end of the connection crossbeam is provided with two rows of threaded holes for settling fixation. Two screw rods for fixing are arranged on each of the two U-shaped connection beams, the screw rods for fixing and the threaded holes for fixing are in threaded fit, and after the screw rods for fixing are taken out of the threaded holes for fixing, the connection crossbeam is capable of sliding bilaterally betweenthe two U-shaped connection beams. The desert land reclamation device has advantages that problems of low land reclamation efficiency, crushing of leak-proof moisture preserving mulch films in mechanical earth covering in existing desert land reclamation, and the like are solved, and a high-efficiency rolling-free land reclamation function is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a desert field making device. Background technique [0002] In the northwest of China, there are large deserts and land with little precipitation. These grounds are completely covered by sand, with very few plants and dry air. The main difficulty in agricultural production in these areas is the lack of precipitation and the large amount of seepage and evaporation in the sandy land. According to the traditional agricultural model, it is difficult to carry out large-scale agricultural production of food crops. [0003] For a long time, people have adopted the following two methods to transform deserts into fertile fields: drilling wells and supporting canal systems in the edge of oases, building small water conservancy projects, and developing irrigation, transforming large areas of sandy wasteland into fertile fields, At the same time, farmland protection forest ne...
