Description

Residual film cleaning and recycling machine spring tooth chain harrow device

Technical Field

The utility model relates to the technical field of agricultural machinery, a plastic film residue cleaning reclaimer bullet tooth chain harrow device specifically says so.

Background

China is the developing country with the most population and relatively insufficient agricultural resources in the world, the wide use of the agricultural mulching technology improves the crop yield in China, greatly promotes the development of agricultural production in China, and the agricultural mulching plays a very important role in modern agricultural production in China at present. The agricultural mulching film has the following advantages:

1. the agricultural mulching film can improve the surface temperature in the growth process of crops, promote the germination of the crops, keep the temperature in the film and simultaneously defend the sudden drop of the external temperature to cause the withering of the plants.

2. The mulching film controls the evaporation of soil moisture, so that most of the soil moisture circulates under the film, the utilization rate of the soil moisture is greatly improved, the mulching film has an obvious soil moisture preservation effect, and the mulching film also has a great effect on promoting the growth of plants.

3. Due to the blocking effect of the mulching film, water and soil and nutrient loss can be prevented, and soil hardening caused by raindrop beating can be prevented. Meanwhile, after the plastic film is covered, the temperature and the humidity of the soil are proper, the permeability is good, and the highest temperature of the soil can reach more than 30 ℃, so that the soil microorganisms are increased, the activity is enhanced, the decomposition and the conversion of organic matters can be accelerated, and the activity and the propagation of beneficial microorganisms in the soil are promoted.

4. After the film is coated, the fertilizer can be deeply applied. Due to the obstruction of the mulching film, the fertilizer is not easy to volatilize, meanwhile, soil microorganisms are active, the decomposition of various nutrients can be accelerated, the absorption of crops is facilitated, the available nutrients in the soil are increased, and the using amount of the fertilizer can be generally saved by about 1/3.

However, the ecological environment of China is greatly damaged while the agricultural production is promoted, the negative effect of environmental protection is more and more concerned by various social circles, the mulching film is planted by using the mulching film technology for a long time, if residual mulching films cannot be reasonably recovered, the mulching film is weathered and decayed to be left in soil after the film uncovering time is too late, and the damage and pollution to the soil caused by long-time accumulation are very serious. Mainly changes the structure of soil and increases the volume weight of the soil, thereby hindering the water permeability of the soil, blocking the development and the permeability of the root system of the plant, being not beneficial to the circulation of soil nutrition and the absorption of rich water, finally causing the reduction of yield caused by late plant germination, slow growth, less tillering and the like. In addition, the production tools can be blocked and wound during planting, which brings inconvenience. Therefore, the residual mulching films need to be cleaned manually, the conventional method is carried out manually, the manual residual mulching film picking cost is high, more and more planters adopt residual mulching film machines to clean along with the development of agricultural mechanization, but the current residual mulching film machines are influenced by the terrain more obviously, the picking effect is poor, the residual mulching films are prone to causing residues of a large number of agricultural mulching films, and the agricultural production requirements are difficult to meet.
