Comprehensive land improvement soil layer stone crushing device and application method

Abstract

The invention discloses a device for crushing rocks in the soil layer of comprehensive land improvement and a method for using it, which belongs to the technical field of agricultural equipment and includes a shell, a crushing device, an arc-shaped pressing plate, a scraping ring and an extrusion device; the inside of the shell is hollow , the top of the housing is provided with a feed port, and the bottom of the housing is provided with a discharge port; one side of the middle part of the housing is provided with an extruding device; the position of the extruding device corresponds to the feeding port; A scraper ring is arranged in the middle of the inside of the housing; the outer side of the scraper ring is connected to the housing by bolts, and the inner side of the scraper ring is provided with vertically arranged hard sawtooth A; in the present invention, the winch and the hard sawtooth A A V-shaped winching area is formed between them, and the incoming stones will be continuously ground until they form particles with the size of the exit between the capstan and the bottom of the hard sawtooth A before they can flow out. The stones are broken evenly, with high crushing efficiency and continuous twisting. The ground stone particles are not easy to have sharp edges and corners, and are suitable for backfilling to farmland for reuse.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to a device for crushing rocks in a soil layer for comprehensive land improvement and a use method thereof. Background technique [0002] Farmland capital construction In order to develop agricultural production, engineering measures or biological measures are taken on the land to build facilities that can exert long-term benefits in production. It is a general term for the measures taken to transform and construct farmland for the purpose of utilizing and transforming nature, developing agricultural production, achieving stable and high yields. The manual crushing of farmland stones requires a lot of work, and the broken stones are not uniform, so they are not suitable for recycling to farmland. However, the existing technology has low crushing efficiency for farmland stones, and the cracks are sharp after crushing. Recycling to farmland for use will thre...

Problems solved by technology

The manual crushing of farmland stones requires a lot of work, and the broken stones are not uniform, so they are not suitable for recycling to farmland. However, the existing technology has low crushing efficiency for farmland stones, and the cracks are sharp after crushing. Recycling to farmland for use will threaten farmland workers. physical and mental health, and at the same time increase the wear and tear on the plowing device, the high cost of farmland construction is not conducive to agricultural mechanized production
