Description
Technical Field
The invention relates to straw forming equipment, in particular to field movable straw forming equipment, and belongs to the technical field of agricultural machinery.
Background
Most of the traditional crop straws in China are discarded or burned by farmers on the spot, which not only causes resource waste, but also causes air pollution by smoke and destroys ecological and natural environment. However, in the process of developing and utilizing the crop straws, the structure is loose and the straws are distributed and dispersed, so that great difficulty is brought to collection, transportation and storage, and the energy density is low, so that the use is inconvenient. One measure to solve the problem is to extrude the loose, fine and amorphous straw into the molded fuel or feed with compact texture and regular shape by using straw molding technology. Although various researches have been carried out in the related fields such as biomass extrusion forming technology, in the actual operation, the storage and preservation of biomass straw raw materials are still the bottleneck of the industry, the straw collection has obvious regionality and timeliness, and when the transportation diameter exceeds 200 kilometers, the transportation cost is greatly increased; when corn is harvested in autumn in most areas of China, winter wheat can be sown, a large amount of proper time cannot be provided for sorting corn straws, and waste straws in fields after autumn harvesting are disordered and have different shapes. The straws abandoned in the field are usually burnt or randomly discarded in the field, so that not only is a great deal of biomass energy wasted, but also the environment is seriously polluted. How to collect and compact the field straw resources in a full-automatic and efficient manner is a key point for realizing industrialization and commercialization of the straw. Therefore, the straw picking, compression molding, enveloping and bundling in the field are developed, and the straw is processed into a material block with a certain shape, higher density and higher moisture retention rate, which has great significance for environmental protection and straw resource utilization. At present, a plurality of agricultural machines are used for compressing and packaging straws in fields at home and abroad, and the patent CN104996073A realizes straw harvesting, compression molding and packaging, wherein the compression molding is cylinder compression, and the coating is self-weight sliding coating, so that the pressure is low, the density is low, the reliability of the self-weight sliding coating is poor, no binding is performed, and a material block is easy to loosen; the patent CN102598964A discloses a compaction and packing device of a straw collection transport vehicle, which comprises a collection device, a compression device and a packing device. The conveying device comprises a grass picking device and a spiral conveying device, the compressing device comprises a compaction oil cylinder and a compaction plate, a guide rod is arranged at the bottom of the compaction plate, and a rope fixing buckle and a rope limiting buckle are arranged on the guide rod. Although straw picking, compression and packing are realized to a certain degree, the unidirectional spiral conveying of the straw picking and packing machine can not realize the pre-compression function, the density of the material blocks is low, and the straw picking and packing machine can not be used for long-term shape maintenance without rope binding and can not realize the moisture retention of the straws without a coating; the patent CN104813811A application discloses a compression type straw collecting and transporting vehicle, the compression device comprises a compaction oil cylinder and a compaction plate, and the compaction plate is pushed by a telescopic connecting rod to move so as to realize straw compaction. The patent is an improvement on a compaction and packing device of a straw collection and transportation vehicle in patent CN102598964A, the basic structures of the two devices are the same, and the latter improves a case night screen analysis and compaction plate for the former. The technical scheme does not have a coating bundling device, is not beneficial to long-term stability and moisture retention of straw forming and is not beneficial to ensiling; the patent CN204616471U authorizes a screw-pushing type bundling and film-coating machine, adopts three-way screw pushing, and utilizes a fiber bag to package materials after the materials are compressed. The material block is pushed into the fiber bag, so that the fiber bag has no wrapping force on the material block, the material block is loose, and the stability of the formed material block is insufficient; in summary, the following problems exist in the use of these devices: firstly, the devices have defects of different degrees on the compactness of the blocks, and are not beneficial to transportation, storage, green keeping and moisture storage; secondly, the equipment with the compression function in the equipment generally adopts the oil cylinder for compression on the compression molding of the straws, and adopts the oil cylinder in at least two dimensions, and adopts the oil cylinder for compression even in three dimensions, although the mode can obtain compact compression blocks, the oil cylinder has a return stroke during compression, continuous feeding can not be realized during operation, and the operation phase ratio is relatively low; thirdly, the equipment is all formed by pressure, the formed material enters a shape-preserving channel, the material is packaged after coming out of the shape-preserving channel, before a compressed and formed material block enters the shape-preserving channel, some materials generally have a throat-shrinking part, the section of the throat-shrinking part is slightly smaller than that of a forming chamber, the size of the throat-shrinking part is equal to that of the shape-preserving chamber, the material block is improved to promote the compact compression of the material block through resistance, the material block further compresses when passing through the throat-shrinking part and then enters the shape-preserving channel, the shape-preserving channel is also called as the shape-preserving chamber, the throat-shrinking part in the existing straw forming setting is surrounded by steel plates and is fixed, although the throat-shrinking effect can be achieved in the forming process, the material block is seriously worn in the using process and needs to be frequently replaced, then, in the straw forming, the material characteristics are not stable, the friction force generated when the material formed in the compression forming process is shrunk is different, the characteristics of various materials in the design in the throat-shrinking form at present, the design, the adaptability is high, the damage rate is obvious, if the straw forming operation characteristics of the straw forming operation are obviously caused, certain equipment, the whole equipment is changed into a short operation time, and the whole equipment, the whole equipment is caused, and the whole equipment is short operation is caused; the straw is molded by adopting a molding process and a shaping process, the molding process adopts compression molding, the shaping process firstly adopts the rope body to wind the material blocks, then coats the material blocks wound with the rope body, and the material blocks are wound in the molding equipment by adopting the rope body, so that a special winding mechanism is needed, a knotter is also needed, the knotter is basically a full-import knotter at present and is high in price, the shaping equipment is complex in structure and high in cost, and the combination part between the plastic film and the rope body except the material blocks is tight during the coating process of the shaping process, so that the rope body is easy to loosen, the material blocks are loosened, and the water loss is caused. And most of the prior field walking equipment can only realize partial functions of picking, forming, bundling and coating and cannot be matched to form a complete field operation system.
