The beneficial effects of the utility model are that the structure is simple relatively, the reliability is high, economy is durable, though draw the fluted roller and rotate and need outside power, nevertheless good to the crushing effect of incomplete membrane, the suction fan easily inhales the incomplete membrane and satisfies the functional requirement that incomplete membrane negative pressure in field was picked up.

Description

Rolling rake type residual film negative pressure collecting device

Technical Field

The utility model belongs to the agricultural machine field relates to a roll harrow formula plastic film residue negative pressure collection device suitable for incomplete membrane in farmland retrieves clearance machinery.

Background

Since the last century, with the rapid development of the plastic industry, the plastic film mulching cultivation technology is widely applied to the fields, has the advantages of preserving heat, preserving soil moisture, inhibiting weed growth, improving soil aggregate structure, increasing crop yield and the like, and is the most effective yield increasing means in the current agricultural production. The mulching film technology is used in europe, the united states and japan since the fifties of the last century, and is rapidly widely used in the world due to remarkable economic benefits, but the agricultural plastic film is extremely difficult to degrade under natural conditions, and if the mulching film is left in soil, a series of serious damages are caused to the agricultural production, so that the mulching film must be timely recycled. At present, the mulching film coverage area and the usage amount of the mulching film are the first in China, the application of the mulching film technology is particularly wide in northeast and northwest areas of China, the cultivated land area of China using the mulching film has hundreds of millions of hectares, the annual mulching film usage amount also reaches millions of tons, and the mulching film becomes one of the essential agricultural production data in agricultural production of China. Because of the price factor, most of the plastic film materials used in China are polyethylene and polyvinyl chloride. The material is not easy to degrade even if being stored in soil for hundreds of years, and a large amount of residual film fragments are left in the soil during recovery, so that the water circulation is not smooth, the soil and air exchange is blocked, microorganisms in the soil are difficult to survive, the soil is hardened, salinization of the soil can be caused in some areas, the crop yield is greatly reduced, particularly, the saline soil is visible everywhere in the field after being blown, buried or burned, the living environment and the air quality of farmers are seriously polluted, and finally, the serious white pollution is caused.

At present, the domestic residual membrane recovery methods mainly comprise 3 methods, namely manual picking, use of a degradation membrane and mechanical recovery. The manual picking has the defects of low efficiency, large labor capacity, limited operation range and the like, and can not recover residual films buried in deep soil. The recycling mode is gradually eliminated along with the reduction of labor force and the improvement of the level of agricultural machinery. The degradable film is a novel environment-friendly mulching film, is mainly prepared by mixing plastic particle master batch and biodegradable master batch, and can be excellently decomposed into soil after being used; however, the degradable film has high cost and immature technology, is difficult to be accepted by broad farmers, particularly small and medium-sized farmers at the present stage, and is limited in domestic popularization. The mechanized recovery mode has the advantages of high efficiency and low cost, and the defects of two recovery modes of manual recovery and degradation membrane are overcome to a great extent. The research on the residual film recycling machinery in China starts earlier, and the earliest related patents can be traced back to the eighties of the last century. Research has been carried out to date, and various residual film recycling machines and tools have been developed, tested and popularized. Nevertheless, the residual film pollution phenomenon is still severe, the problems of low recovery rate of the residual film recycling machine and the like can not be solved well all the time, and most of areas still rely on manual residual film picking. In order to further improve the residual film recycling quality, the functional parts of the existing residual film recycling machine need to be researched systematically, carded and summarized in the structural characteristics and the operation principle, so as to provide guidance for further design and optimization of the residual film recycling machine.

Disclosure of Invention

In order to solve the requirement of recovering and cleaning the residual mulching films in the farmland, a rolling rake type negative pressure residual mulching film collecting device is developed, and the device can scrape the mulching films and suck the broken mulching films into a residual mulching film box from the ground surface.

The utility model provides a technical scheme that its technical problem adopted is: a rolling rake type residual film negative pressure collecting device comprises a suction fan, a semi-closed type film collecting shell, a driving shaft, scratching teeth and scratching tooth rollers, wherein the suction fan is arranged at the upper part of the semi-closed type film collecting shell; the lower part of the semi-closed membrane collecting shell is provided with an opening; a gear scratching roller is arranged on the front side of the semi-closed type membrane collecting shell; a driving shaft is arranged on one side of the gear marking roller; the surface of the scratching roller is provided with scratching teeth.

The beneficial effects of the utility model are that the structure is simple relatively, the reliability is high, economy is durable, though draw the fluted roller and rotate and need outside power, nevertheless good to the crushing effect of incomplete membrane, the suction fan easily inhales the incomplete membrane and satisfies the functional requirement that incomplete membrane negative pressure in field was picked up.
