Backfilling equipment for saline-alkali land closed conduit trench

Abstract

The invention relates to the technical field of engineering machinery and discloses backfilling equipment for a saline-alkali land closed conduit trench. The backfilling equipment comprises a pedestal. A power device is mounted on the right side of the top of the pedestal; two sets of rollers are mounted on the center position of the bottom of the pedestal; a top plate is installed on the top of a hydraulic rod; the left side of the top is provided with a damping device; the left side of the damping device is provided with a soil baffle plate; a soil pushing plate is arranged on the bottom of the soil baffle plate; an adjusting device is mounted on the bottom of a cavity of the power device; a scraping plate is arranged on the bottom of the adjusting device; the soil pushing plate can be controlled by a hydraulic device to move up and down, so soil can be backfilled once for all; a corrosion-resistant layer can prevent saline-alkali in the saline-alkali land corroding the soil pushing plate; with a wear-resistant layer, the soil pushing plate cannot shorten service life due to long time use; the backfilling equipment can be conveniently used; and backfilling can be achieved, the land can be flattened, and the backfilling equipment has long service life.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a device for backfilling a concealed pipe groove in saline-alkali ground. Background technique [0002] The general method of soil improvement in saline-alkali soil is to bury hidden pipes in the saline-alkali land, and use fresh water irrigation to gradually concentrate the salt in the upper layer of the soil as the water level drops. Use the hidden pipes to discharge salt. The laying of hidden pipes now has a special pipe buried machine , The pipe burying machine digs a trench on the ground, and at the same time lays a concealed pipe with a salt discharge port on the bottom of the trench, and then backfills the excavated soil. In the process of soil sample backfilling, the current commonly used method: manual backfilling, The amount of work is large, the manual backfilling speed is slow, and the efficiency is low. Using forklifts and other mechanical tools to backfill,...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of backfilling equipment for underground pipe trenches in saline-alkali land, to solve the manual backfilling proposed in the above background technology, the engineering volume is large, the manual backfilling speed is slow, and the efficiency is low. Mechanical tools such as forklifts are used for backfilling, and the backfilling speed can be reduced. It’s not bad, but it’s not a professional tool. The forklift has high fuel consumption, high cost, poor ground flatness after backfilling, etc. It needs to be cleaned up in the later stage, and the problem of secondary work
