Abstract
The utility model discloses a farm crop stubble breaking and land-returning machine. The utility model takes a power take-off shaft of a motor of a small-sized hand tractor as power supply which is formed by directly connecting a belt pulley to a drive shaft of a stubble breaking mechanism without changing speed. One end of an arm of the stubble breaking mechanism is fixed to the position of a drag card, and the other end of the stubble breaking mechanism is sleeved on a bearing seat of the drive shaft of the stubble breaking mechanism. An operation rod of the clutch of the stubble breaking mechanism utilizes a fixed latch placed on a handle of the tractor to position, and a safety protective cover positioned on the upper side of a knife roller of the stubble breaking mechanism is designed in a shape with various radiuses, namely a safety protective cover with various radiuses of which the intermediate radius is the largest, the radius of the front end is the smallest and the radius of the rear front end is larger than the radius of the front end and is smaller than the intermediate radius.
Description
The utility model relates to a kind of crops machine for crushing stubble and feeding it into field, belongs to the agricultural machinery class.
At present, three grades of transmissions of the many employings of stubble cutter overall structure, promptly power is passed to gearbox by the hand tractor engine, pass to the power transmission shaft of stubble cutter structure again by the power take-off of gearbox, drive the rotor rotary operation by power transmission shaft again, because rotating speed is low, hand tractor can only keep off operations with one, two, fuel consumption is big, efficient is low, and fault is many, maintenance is adjusted inconvenient; Have, originally the protective cover of stubble cutter top has only the security protection effect again, and misconvergence holds together native function, causes after the operation of broken stubble, and the regolith is broken up, and ridge is paved, and also need increase by one making ridge work.
The utility model provides a kind of crops machine for crushing stubble and feeding it into field at the problems referred to above, and it can overcome low, the low drawback of efficient of complex structure, rotating speed that three grades of transmissions bring, and can solve broken stubble back ridge platform again and be tied making ridge problem again.
Task of the present utility model is finished as follows: this novel complete machine is made up of power transmission and stubble cutter structure two parts, power adopts the small hand tractor engine power output shaft, directly be associated on the stubble cutter structure power transmission shaft without speed change by belt pulley, the end wheel of gearbox clutch cooperates with belt as regulating wheel, arm one end of stubble cutter structure is fixed on the draw bail position, the other end is enclosed within on the bearing block of stubble cutter structure power transmission shaft, and the control stick of stubble cutter structure clutch adopts on the tractor handle fixedly gib location; Safty shield on the stubble cutter structure rotor is designed to reducing shape, that is: middle radius maximum, the front-end radius minimum, back-end radius holds together the soil cover greater than front-end radius less than the reducing shape security protection of middle radius.
The utility model is because power adopts the small hand tractor engine power output shaft, directly be associated on the stubble cutter structure power transmission shaft without speed change by belt pulley, the end wheel of gearbox clutch participates in speed change synchronously and not with engine output shaft, variable one, two retaining operations are three, four retaining operations, the speed height, can make mechanical oil consumption reduce by 1/3rd, and root stubble degradation rate height, not having the stubble cripple exists, simple in structurely be convenient to maintenance and repair, arm one end of stubble cutter structure is fixed on the draw bail position, the other end is enclosed within on the bearing block of stubble cutter structure power transmission shaft, can make in fixing stubble cutter structure power axle bearing, the lifting needs of stubble cutter structure when satisfying operation with walking, the control stick of stubble cutter structure clutch adopt on the tractor handle fixedly the gib location to be convenient to operation; Stubble cutter structure rotor top safty shield is designed to reducing shape, that is: middle radius maximum, the front-end radius minimum, back-end radius holds together the soil cover greater than front end less than the reducing shape security protection of middle radius, can make and break up the soil kicked up through rotor and draw in through ridge soil cover and fall and form the ridge platform again, make crops in root stubble chopping and returning, soil property is also by loose, save the labour, be convenient to arviculture.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Fig. 1 is the utility model overall structure figure
With reference to accompanying drawing 1, this novel complete machine adopts small hand tractor [1] and stubble cutter structure [5] to constitute, the tractor engine output shaft, directly be associated on the power transmission shaft [6] of stubble cutter structure [5] without speed change by belt pulley [2], the end wheel [3] of gearbox clutch cooperates with belt [4] as regulating wheel, arm [7] one ends of stubble cutter structure [5] are fixed on the draw bail position, the other end is enclosed within on the bearing block of stubble cutter structure power transmission shaft, and the control stick [8] of stubble cutter structure clutch adopts on the tractor handle fixedly gib [9] location; Safty shield on the stubble cutter structure rotor [10] is designed to reducing shape, that is: middle radius maximum, the front-end radius minimum, back-end radius holds together soil cover [11] greater than front-end radius less than the reducing shape security protection of middle radius.
Claims (1)
1, a kind of crops machine for crushing stubble and feeding it into field, complete machine is made of small hand tractor [1] and stubble cutter structure [5], it is characterized in that: engine power output shaft, directly be associated on the power transmission shaft [6] of stubble cutter structure [5] without speed change by belt pulley [2], the end wheel [3] of gearbox clutch cooperates with belt [4] as regulating wheel, arm [7] one ends of stubble cutter structure [5] are fixed on the draw bail position, the other end is enclosed within on the bearing block of stubble cutter structure power transmission shaft, and the control stick [8] of stubble cutter structure clutch adopts on the tractor handle fixedly gib [9] location; Safty shield on the stubble cutter structure rotor [10] is designed to reducing shape, that is: middle radius maximum, the front-end radius minimum, back-end radius holds together soil cover [11] greater than front-end radius less than the reducing shape security protection of middle radius.
