Description

Composite vibration type mouse road plough Technical Field The invention relates to the field of agricultural machinery. More particularly, the present invention relates to a compound vibratory murine plow. Background The rat-way drainage technology is an effective farmland underground drainage measure, and forms a cave channel in the deep layer of soil to lead out redundant underground water or upper layer stagnant water from farmland, thereby reducing the underground water level, improving the soil ventilation and promoting the growth of crop root systems. In areas with large rainfall or high groundwater level, soil logging is one of the main factors limiting agricultural production, and the problem can be effectively solved by adopting an underground drainage system formed by a murine plow, so that crop yield and farmland sustainable utilization capacity are obviously improved. The existing mouse-way plough is divided into two major categories, namely traction type and suspension type. The traction type mouse-way plough is dragged by a tractor and is extruded by a coulter soil cutting and hole shaping device to form a mouse-way, and the suspension type mouse-way plough is connected with the tractor through a three-point suspension device and is controlled to lift by a tractor hydraulic system during operation. In recent years, a vibrating type mouse-way plow is gradually applied, and a vibrating mechanism is arranged on a frame to enable the whole frame and all plow heads to jointly vibrate, so that soil resistance is reduced, and soil penetration performance is improved. The integral vibration mode has certain effect in clay and heavy loam, and is the main development direction of the current murine plow technology. However, the existing vibrating murine plow has obvious disadvantages. Firstly, the vibration energy is dispersed in the whole vibration mode, a large amount of energy is consumed by the frame, the effective energy really applied to soil cutting occupies a relatively low proportion, secondly, the severe vibration of the whole frame is directly transmitted to a tractor through a suspension device, the driving comfort and the service life of a tractor key part are seriously affected, thirdly, all ploughshares adopt uniform vibration frequency and amplitude and cannot be differentially regulated according to the soil hardness actually encountered by different ploughshares, the adaptability is poor, and in addition, the fatigue strength requirement of the whole vibration on the frame structure is extremely high, the frame is easy to crack, and the equipment maintenance cost is high. Therefore, it is necessary to provide a novel compound vibrating type mouse-way plow to solve the above-mentioned problems in the prior art. Disclosure of Invention The invention provides a compound vibrating type mouse-way plow which realizes energy concentration, resistance reduction and synergy, comfort and durability through an independent vibrating plow head, an elastic suspension vibration isolation and a compound impact mechanism.
