Description

Traction type residual film recycling machine rake tooth device

Technical Field

The utility model relates to the technical field of residual film machines, in particular to a drag tooth device of a traction type residual film recycling machine.

Background

The agricultural mulching film is widely used in developing countries with the largest population and relatively insufficient agricultural resources, so that the yield of crops in China is improved, the development of agricultural production in China is greatly promoted, and the agricultural film plays a role in modern agricultural production in China at present. The agricultural mulching film has the advantages that:

the agricultural mulching film can raise the surface temperature during the growth of crops, promote the germination of crops, and prevent the sudden drop of external temperature while maintaining the internal temperature of the mulching film, thereby causing the plant to be withered.

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

Due to the blocking effect of the mulching film, water, soil and nutrient loss can be prevented, and the hardening of the ground soil caused by raindrop beating can be prevented. Meanwhile, after plastic film mulching, the soil has proper temperature and humidity and good permeability, 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 conversion of organic matters can be accelerated, and the activity and propagation of beneficial microorganisms in the soil are promoted.

After the film is covered, the chemical fertilizer can be deeply applied. Because of the obstruction of the mulching film, the fertilizer is not easy to volatilize, and meanwhile, the soil microorganisms are active, so that the decomposition of various nutrients can be accelerated, the crop absorption is facilitated, the available nutrients in the soil are increased, and the fertilizer consumption can be generally saved by about 1/3.

However, the agricultural production is promoted, meanwhile, the ecological environment of China is also greatly harmed, the negative effect of environmental protection is also more and more concerned by various social circles, if the residual film cannot be reasonably recovered after long-term use of the film covering technology, the film uncovering time is too late to lead the mulch film to be weathered and rotten and remain in soil, and the damage and pollution to the soil are very serious after long-time accumulation. Mainly has the functions of changing the structure of soil, increasing the volume weight of the soil, thereby blocking the water permeability of the soil, blocking the development and permeability of plant root systems, being unfavorable for the circulation of soil nutrition and the absorption of fertilizer and water, and finally leading the plants to have late germination, slow growth, few tillers and the like so as to reduce the yield. In addition, the production tool is blocked and wound during planting, so that inconvenience is brought. Therefore, the plastic film residue film needs to be cleaned, various plastic film residue film recovery devices are available in the market at present, but the plastic film residue film recovery device is not suitable for the places with deeper roots of corn fields, the plastic film residue film recovery device is easy to clamp on the roots of corn, and the plastic film residue film cannot be picked up and recovered, so that the plastic film residue film recovery device for the places with deeper roots of corn fields is developed by our company, but the plastic film residue film recovery device is difficult to meet the requirements of the plastic film residue film recovery device in the market at present due to the fact that the spring tooth structure is found.

Further, the surface of the rake teeth fixing cylinder is covered with a rubber plate, and the rubber plate covers the elongated holes penetrating through the surface of the rake teeth fixing cylinder.

Further, in order to provide a good rebound effect after the spring tooth leaves the ground, the columnar structure of the spring tooth is located at the front side when running to the bottom, and the torsion spring structure is in a compressed state when the bottom spring tooth is in contact with the ground.

Further, in order to ensure smooth rotation of the rake teeth fixing cylinder and reduce abrasion to the rotating shaft, bearings are sleeved outside the rotating shafts at all ends respectively.
