Description
Technical Field
The utility model relates to the technical field of agricultural machinery, a plastic film residue cleaning reclaimer bullet tooth chain harrow three-bar linkage adjusting 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 mulching 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 fertilizer dosage 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. Need clear up the plastic film incomplete membrane for this reason, traditional approach adopts the manual work to go on, and it is with high costs to artificially pick up incomplete membrane, and along with the development of agricultural mechanization, more and more planting family adopts incomplete membrane machine to clear up at present, but present incomplete membrane machine receives the topography to influence more obvious, is not convenient for adjust, leads to operating condition unstability easily, and the effect is picked up in the influence of edge plough layer, still can influence equipment life.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model aims to provide a three-connecting-rod adjusting device of a spring tooth chain harrow of a plastic film residue cleaning and recycling machine.
In order to achieve the above purpose, the technical scheme of the utility model is that: a three-connecting-rod adjusting device for an elastic-tooth chain harrow of a residual film cleaning and recycling machine comprises an elastic-tooth chain harrow support and an adjusting and supporting rotating shaft of the elastic-tooth chain harrow support, wherein the adjusting and supporting rotating shaft of the elastic-tooth chain harrow support is respectively fixed at the middle parts of two sides of the elastic-tooth chain harrow support, the adjusting and supporting rotating shaft of the elastic-tooth chain harrow support penetrates through and is supported in a rotating shaft supporting sliding block at the tail end of a machine frame, the rotating shaft supporting slide block is clamped between an upper slide block clamping plate and a lower slide block clamping plate which are parallel to each other at the tail end of the main body of the stand, a vertical plug pin inserting groove is arranged at the tail end of the supporting slide block, the horizontal section of the plug pin inserting groove is semicircular, a slide block fixing stop pin passing through the plug pin inserting groove is vertically penetrated through the tail ends of the two parallel slide block clamping plates, the rotating shaft supporting slide block is limited and fixed between the two parallel slide block clamping plates through a slide block fixing stop pin inserted into the plug pin insertion groove, and the bottom parts of the two sides of the elastic tooth chain harrow support are respectively connected with the bottom part of the tail end of the machine frame in a rotating mode through a thread adjusting rod;
through the arrangement, the elastic tooth chain harrow support of the elastic tooth chain harrow device is supported at the tail end of the frame in a rotatable adjusting mode, the inclination angle of the elastic tooth chain harrow device can be adjusted according to the terrain, the supporting rotating shafts of the elastic tooth chain harrow support at two ends of the elastic tooth chain harrow device are adjusted and supported in the supporting sliding blocks in a rotating mode, the supporting sliding blocks are fixed in a non-welding inserting mode, in the long-term working process, due to the influence of different frictional forces on the ground, the elastic tooth chain harrow device actually rotates slightly and moves continuously, so that the elastic tooth chain harrow support at two ends of the elastic tooth chain harrow device adjusts the continuous friction between the supporting rotating shafts and the supporting sliding blocks, the wear of the rotating shafts of the supporting sliding blocks is easily caused, the continuous wear of the rotating shafts of the supporting sliding blocks is increased, the accuracy of the adjusting angles of the elastic tooth chain harrow device is influenced, and the stability of the elastic tooth chain harrow device is supported by the, the supporting slide block can be taken down by pulling down the fixed stop pin of the slide block, so that the supporting slide block can be more conveniently replaced while the angle adjustment is ensured, and in addition, the procedures of welding and the like are also reduced by adopting the mode to fix the supporting slide block, and the equipment is also convenient to assemble and disassemble.
In conclusion, the utility model can adapt to various terrain operations, and can contact with the ground more effectively, thereby ensuring the residual film to be cleaned and recovered thoroughly and uniformly; the angle of the three-connecting-rod adjusting device is flexibly and simply adjusted, and the three-connecting-rod adjusting device is convenient to mount and dismount and convenient to maintain.
