Multifunctional machine capable of raking, overturning and ploughing field to circularly remove stubble and smash and return straw to field for ridging

Abstract

The invention discloses a multifunctional machine capable of raking, overturning and ploughing a field to circularly remove stubble and smash and return straw to the field for ridging. The machine which comprises a walking frame body, a moving frame, a cover plate, a tray, a conveying device, a reamer device, a device for racking, screening and stirring, a reamer cover, a file, an engine, a gearbox, a hydraulic press, a power generator, a hydraulic driving device, hydraulic retractable devices, rubber crawlers, crawler wheels, crawler shafts, supporting rollers, towing shafts, screw rods, a pulverizer, a chamber cover, front floodlights, rear floodlights, a seat, a chamber door, a front floodlight switch, a rear floodlight switch, an engine switch, a guide pipe and plough blades. The walking frame body is inserted into and overlapped with the moving frame; under the cooperation of the conveying device, the reamer device, the device for racking, screening and stirring and the reamer cover, the effects of racking, overturning and ploughing the field, removing stubble and picking straw and fallen branches and leaves of crops or circularly smashing plants growing naturally in order toreturn the plants into the field for ridging are achieved; the machine is not limited by the size of slopes, depressions and plots or the number of ridges, and the ridge number is freely selected in arange from 1 to 4. The machine is safe, reliable, easy to operate, capable of saving time and labor, low in cost and long in service life.

Description

technical field [0001] The invention relates to an agricultural machine for plowing, plowing, stubble removal, straw crushing, returning to the field and ridge, in particular to a multi-functional machine for plowing and plowing, stubble removal, straw crushing, returning to the field and ridge. Background technique [0002] China is a large country in the development of agriculture. The basic way of farming crops is that after the crops are harvested, autumn plowing or spring plowing is required to ensure that there is a suitable loose soil for planting new crops. The problem of poor water and moisture conservation and other problems of the quality of cultivated land has appeared; at present, the agricultural implements sold on the market include: ox-drawn plows for plowing and plows pulled by tractors; artificial rakes are labor-intensive and inefficient. Agricultural tractors are used to stack and burn on one side to pollute the environment; most of the crop stubble in ag...

Problems solved by technology

[0002] China is a large country in the development of agriculture. The basic way of farming crops is that after the crops are harvested, autumn plowing or spring plowing is required to ensure that there is a suitable loose soil for planting new crops. The problem of poor water and moisture conservation and other problems of the quality of cultivated land has appeared; at present, the agricultural implements sold on the market include: ox-drawn plows for plowing and plows pulled by tractors; artificial rakes are labor-intensive and inefficient. Agricultural tractors are used to stack and burn on one side to pollute the environment; most of the crop stubble in agriculture is installed on the tractor with a stubble remover. When the soil is plowed and loosened, the ridges cannot be combined. The remaining straw branches and leaves in the crop field and the weeds of the natural growth plants cannot be crushed and returned to the field, and the stubble cannot be crushed and mixed with the soil, and the stubble cannot be crushed back and forth to grow the natural plants. Weeds, etc.; after the land is cultivated, it seriously hinders the rooting of crops and the absorption of water and nutrients in the deep soil, which directly affects the yield and quality of crops; at the same time, because farmers have used the land for many years and lightly cultivated it, in order to pursue the yield year after year Excessive use of chemical fertilizers and pesticides every year has resulted in soil compaction, which has also affected the yield and quality of crops; plowing the ground by plowing stubble, crushing stubble, straw and weeds mixed with the soil improves the water permeability and air permeability of the soil, and provides better plant roots. The vast stretching field creates a good living environment for the microorganisms in the soil and promotes the potential fertility of the soil; the crushed stubble, straw and weeds are mixed with the soil to improve the soil, and the crushed stubble, straw and weeds gradually evolve into organic matter content and aggregate structure. Formation, the surface soil is loose and fertile, turning the soil into a virtuous cycle; the soil becomes looser and the roots of the crops stretch to absorb more ingredients, and the roots of the crops root down to absorb the water and nutrients in the deep soil to improve the yield and quality of the crops; in addition, China's saline-alkali land It is 99.12 million hectares; most of the formation of alkaline soil and alkalized soil in China is related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. The saline-alkali land is wasted as a very precious land resource. Planting plants on saline-alkali land can inhibit soil erosion, improve the ecological environment, and improve the soil. Hard saline-alkali land is different from planting seeds on flat and soft land. As long as a ditch is opened on the land, it can be planted; while sowing seeds on saline-alkali land requires people to use machinery to participate in pulling plows to open furrows and sow seeds; It evolves into a gradual increase in organic matter content, a gradual formation of aggregate structure, loose and fertile surface soil, turning the soil into a virtuous cycle and reducing the salinity of the land, so that the crops have enough soil moisture and nutrients to ensure the yield and quality of the crops; China's traditional agricultural machinery Compared with developed countries, there is a big gap, and it is far from being able to adapt to the progress of agricultural science and technology; with the advancement of science and technology, the automation level of mechanical products continues to increase, and more and more advanced automation technologies are widely used in industrial fields, but agricultural automation technology The overall level is still relatively low; in recent years, the research on automation has been gradually recognized by people, and its application has been paid more and more attention; in the field of agricultural production, plowing the loose land before sowing to form ridges, and stubble removal are all production At the beginning of the work, the above-mentioned products have a single function, repetitive labor, waste of fuel, laborious and labor-intensive, and have a better effect on large-area flat land. For small land such as mountains and hills, the use of this application can effectively solve the aforementioned problems. question
