Traction-type subsoil fertilization and soil-rock separation machine

Abstract

The invention discloses a trailed subsoiling and fertilization integrated soil-stone separation machine, relates to an agricultural soil-stone separation machine, in particular relates to a subsoiling and fertilization integrated soil-stone separation machine for gravel-mulched lands, and is mainly applied to renewing old gravel-mulched lands. The trailed subsoiling and fertilization integrated soil-stone separation machine comprises a frame, chain-type scraper devices, a vibrating screen, a subsoiler fertilization device and a transmission device, wherein the chain-type scraper devices are used for scraping soil on shovel heads and realizes separation during running along the vibrating screen; shovel plates on the chain-type scraper devices is respectively in a shape of a downward concave arc; elastic scrapers of the chain-type scraper devices are bent into hooks; the chain-type scraper devices and the vibrating screen are connected together through draw cords; the front ends of the chain-type scraper devices are connected with the frame through two hydraulic cylinders having the same structures; and the two hydraulic cylinders can act synchronously by a synchronous valve in front of the two hydraulic cylinders. The trailed subsoiling and fertilization integrated soil-stone separation machine is high in working efficiency and relatively low in energy consumption and has the functions of subsoiling and fertilization.

Description

Technical field [0001] The invention relates to a soil-rock separator for agricultural machinery, in particular to combined operation equipment used for loosening, fertilizing and re-covering the ground surface with separated sand and stone in aging sandy soil. Background technique [0002] Covering the surface with a layer of about 12cm pebbles in arid areas is called sand-pressing and moisture-conserving technology. At present, only in Zhongwei City, Ningxia, there are nearly one million mu of selenium melons planted on sand-pressed land, which has become a dominant and characteristic industry in this area. benefit greatly from industrial development. However, after 5 years of planting, these sandy fields generally begin to greatly reduce their yield and melon quality due to the loss of fertility, and they need to be supplemented with fertility. The mechanical agitation of fertilization makes the sand and gravel blocks (hereinafter referred to as sand and gravel) covered o...

AI Technical Summary

Problems solved by technology

Since the vibrating screen is driven by a high-speed crank-rocker mechanism, it consumes a lot of power and has low efficiency. In particular, the blade is integrated with the screen close to the ground, and the screen surface is limited by the suspension capacity of the tractor. None of the effects can meet the production requirements for character recovery in sand fields, and have not been put into production

[0004] Ningxia Zhongwei Shangfengzi Machinery Research and Development Co., Ltd. adopts a sand and stone separator improved by a medicinal material excavator. This machine also uses a crank rocker vibrating screen mechanism. Due to tractor suspension and space constraints, there is no forced lifting mechanism for materials. It is dovetail-shaped. Flat plate fixed shovel, single-layer sieve is close to the ground to pick up materials. During work, blockage easily occurs at the shovel head, which increases the traction resistance, and because the sieve hole is too large (15mm), many gravels are still mixed in the soil, resulting in sand. The boundary between rock and soil layer is not obvious
