Description

Combined plough for straw deep-burying processor

Technical Field

The utility model relates to a combined plough for a straw deep-burying processor.

Background

Crop straws are always low in utilization rate for a long time and are usually directly abandoned in farmlands or burnt on the spot, so that fire hazards are easily formed, life and property safety of people is endangered, resource is greatly wasted, environmental air is seriously polluted, and a soil structure is damaged. In recent years, agricultural planting completely depends on chemical fertilizers to provide nutrients for plant growth, the application amount of the farmyard manure is almost zero, and the production belongs to plunder production, so that humus in soil is completely absorbed by plants growing in successive years, the original black land is gradually changed into yellow land, and the soil hardening and desertification phenomena are serious. In addition, the straw returning methods implemented in recent years comprise straw turning and pressing returning, straw mixed burying returning, straw covering and returning and other modes, and the methods have the problems that the returned straws are mixed in soil of a cultivation layer, so that the soil is loose and not solid and the wind is leaked, seeds are germinated and emerge unevenly, and the straws compete for nitrogen in the soil with seedlings when decomposed in the soil, so that the growth and development processes of the seedlings are influenced. The methods have the defects of unscientific mode, incomplete method and poor effect, namely, the method does not play a good role in promoting the next crop cultivation and has large negative effect on the next crop cultivation, so the currently adopted straw returning mode is extremely undesirable. Also 1, developed by agricultural machinery research institute of tropical agricultural academy of sciences in china [ sugarcane leaf grinding deep burying combine ] patent nos: cn103340062.a; 2. the patent number of [ straw deep layer gathers buries wedge type hollow plough ] that Jilin agriculture university developed: CN 106471884A; 3. "straw deep scarification burying machine" developed by Liaoning seawide machinery manufacturing Co., Ltd.): CN 107027363A, etc., which are treated by deep burying of straw and leaves, but have the following defects: 1. the crushed straws thrown into the ditch in the deep burying process are partially blown out of the ditch before being buried by soil. 2. Furthermore, the ground surface straws are not uniform, and the burying amount can not be uniform in the process of no storage and buffering. 3. When meeting a section with more concentrated straws or the quantity of straws is natural, the straws are not buried in the soil and are exposed on the ground surface. 4. The power consumption is large when buried. 5. A part of the landfill may affect the growth of plants in the next season. When in next season cultivation, the plants are ploughed out and mixed into soil or on the ground surface, thus achieving the purposes of quick decomposition and no influence on the growth of next-crop plants.

In the specific implementation, the straw crushing and recycling machine with the supporting wheels and the suspension bracket is a product purchased from Funiu Xinxing mechanical equipment Limited, and has the model of 2800 type straw crushing and recycling machine, a self-contained component frame plate, a main power gearbox, the suspension bracket, a power transmission shaft, a fan, a straw secondary crusher, a conveying pipe, a belt, a fixed cutter, a movable cutter, a spiral conveyor groove body, a spiral conveyor auger, a supporting wheel and a supporting wheel arm, in order to ensure the integrity and the uniform stress of the machine, when the manufacturer produces, the rear parts of end plates at two sides of the machine are lengthened so as to meet the requirement that a supporting fixing plate 18 can be horizontally welded between lengthened parts to form an integral frame, two high-low adjustable supporting wheels 17 are self-contained, the principle is that the fixed end of the supporting wheel arm 19 is two concentric porous rotating disks, one of the concentric rotating disks is welded on a steel beam connected between two lengthened frame plates at the front end of a combined plough 10, the other concentric rotating disk is welded at the fixed end of the supporting wheel arm 19, the two concentric porous rotating disks are welded at the vertical plane of the supporting wheel arm, the two concentric rotating disks of the supporting wheel 17, the three types of the power gearbox, YT 36-1R 1-539 mechanical bearing, the power gearbox, the mechanical bearing of a power gearbox, a third power gearbox, a mechanical bearing, a third power gearbox, a factory, a mechanical bearing.

Under this kind of processing apparatus, smash the straw and arrange in succession evenly forcing in burying plough box abdominal cavity of plough box deeply, accomplish burying under soil moreover, the phenomenon can not appear dark shallow thin and thick inhomogeneous and excessively emerge, so still field unanimous, soil has also obtained dark pine and equivalent improvement simultaneously.

The machine realizes the following application effects which should be obtained from returning the straws to the field theoretically from the function and the field cultivation method: 1. increase the nutrient content of the soil and avoid the loss of nutrients in the straws. 2. Increase the organic matter content of the soil, improve the soil structure and the microbial environment, thereby improving the physical properties of the soil. 3. The reasonable straw disposal is beneficial to the cultivation in the next season and the occupied area of the accumulated straw is avoided. 4. Eliminating the pollution of straw burning to environment. 5. The fertilizer consumption is reduced, and the cost is saved.

Use the utility model discloses, begin to carry out the straw and bury still field operation deeply after crops results, break into the furrow and bury the straw below the plough bottom with the broken stubble of ridge platform after, and the furrow of this year is piled up into the basic position that the ridge was sowed as the spring of next year. And (3) continuously removing stubbles of the ridge platforms at that time to break into furrows after harvesting in autumn of the second year, continuously burying straws deeply below the furrow plough bottom layer, piling the furrows in the second year to form a part of the ridge platform serving as a sowing foundation in spring of the third year, burying a straw humus layer buried in autumn of the first year under the ridge platform during sowing in spring of the third year, and having no influence on the growth process of plants in the same year due to rotting and decomposition in the last two years. When the ridge is broken to bury the straws after harvesting in autumn of the third year, the straws which are buried in autumn of the first year and are decomposed after more than two years are decomposed, and the straws are completely changed into humus which is ploughed out and mixed in soil to become fertilizer. Therefore, the straws are circularly deeply buried and ploughed in the soil at intervals year after year, so that the decomposed straws buried three years ago become fertilizers and are ploughed out and mixed in the soil every year from the beginning of burying the straws in autumn in the third year, and as shown in figure 1. The humus in the soil is increased year by the cyclic burying and ploughing out, the soil fertility is effectively supplemented, and the soil becomes more fertile and becomes an important fertilizer source foundation for developing agriculture. The straw is scientifically utilized as a fertilizer, and is a key link for realizing the strategy of agricultural sustainable development. In addition, the thickness of the straw soil layer buried under the furrow plough layer is about 10 centimeters every year, the temperature required by the decomposition can be fully obtained when the straw soil layer is shallow from the ground surface, in addition, the excessive rainwater is concentrated in the furrow to permeate downwards when raining, the proper humidity is provided for the decomposition of the straw, and in addition, the effects of a large amount of bacteria and microorganisms contained in the soil and the like can accelerate the decomposition process of the straw.
