Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and more specifically, it particularly relates to a film mulching device for saline-alkali soil. Background Technique

[0002] Saline-alkali land refers to land containing soluble salts in the soil. The film mulching of saline-alkali soil can effectively isolate the contact between the soil and the atmosphere, limit the evaporation of water and the migration of salts in the soil, thereby reducing the salt concentration in the soil and preventing the salts in the saline-alkali land from accumulating on the soil surface with the evaporation of water, which has an adverse impact on crop growth.

[0003] According to a film mulching machine for saline-alkali soil disclosed in the application number: CN202310616132.6, which includes a frame body. Four support plates are fixedly installed on the outer side of the frame body. Support cylinders are fixedly installed inside the four support plates. A number of threaded hoops are fixedly sleeved inside the support cylinders. A stud is threadedly connected inside the threaded hoops. The bottom end of the stud is sleeved with a support shaft seat. A sliding column is fixedly installed at the bottom of the support shaft seat. A moving wheel is movably installed at the bottom end of the sliding column. Slide bars are fixedly installed on both sides of the sliding column. By setting the stud, when it is necessary to adjust the protruding height of the moving wheel, the stud can be rotated at this time. After the stud rotates, under the action of the threaded connection with the threaded hoop, it rotates and protrudes to push the support shaft seat downward, so that the sliding column protrudes. Under the fitting sliding limit action of the sliding column and the slide bar inside the support cylinder, it is convenient for protruding adjustment. After adjustment, insert a bolt into the flange plate, and fix the position of the stud through the flange plate and the bolt, which is convenient for stabilizing the adjusted position, and the overall use effect is good.
