Description
Technical field
The present invention relates to agricultural machinery technological fields, and in particular to a kind of crawler type water chestnut combined harvester.
Background technology
Easy kind of water chestnut is difficult to receive, and hand digging efficiency is low, and intensity is big, and operating environment is severe, and (water chestnut is generally received after entering the winter
Obtain, weather is cold), constrain intensive, the large-scale production of water chestnut.To realize water chestnut mechanized harvest, burnt loyal equal (it is burnt loyal,
A kind of water chestnut diggers of Wang Chengjun, Wang Shuai [P] China, 201110112088,2011-10-05.) design a kind of water chestnut drought
It receives excavator to be excavated by mouldboard plow using wheeled tractor as power, rotary-cut breaker carries out water chestnut and soil point
From, then manually picked up；(Chen Haifeng, Zhang Shixi water chestnut collection ships excavate mechanism and the Structural Design [J] to Chen Haifeng etc.
.2013 the research for) carrying out water chestnut collection ship, devises a kind of paddy field cropper, using boat-type tractor as power, using swinging
Separation is realized by the water knife inside excavating gear while grizzly bar digger blade is excavated；Wang Chuan (Wang Chuan, Liu Hui, Wang Liwei,
Wang Wei, master-plan [J] Agriculture Mechanization in China journals of the high water chestnut harvesters of king, 2017.) a kind of water chestnut harvester is disclosed,
Using wheeled tractor as power, water chestnut is dug out using digger blade, realizes soil in water chestnut by separator and flusher
Separation；Since water chestnut harvest mud foot is deep, soil viscosity is high, and in the above method, wheeled tractor sink, and mud foot is deep, and boat form is dilatory

53 back outlet of net accepts the water chestnut washed by spiral brush sifter cleaning machine 11 and is conducted into water chestnut vasculum 15.
As shown in figure 9, in transmission system, the power exported after engine is transferred to reduction box 60, reduction box by belt
60 will reach spiral brush washer 11 by reduction box bevel gear 61 after power, power is forwarded to belt wheel transmission by belt
10 first pulley 48 of mechanism, power drive driving wheel 42 and master after belt is transmitted to 10 first pulley 48 of belt wheel transmission mechanism
Third sprocket wheel 49 on the left of driving wheel and the second belt wheel 51, power are transferred to direction vibration separator 9 by third sprocket wheel 49, the
Two sprocket wheels 51 pass sequentially through belt wheel transmission mechanism, the first helical gear 70 and the second helical gear 64 and are forwarded to the power of engine greatly
Inclination angle conveying device 4, when hydraulic system reduces digging system, the first helical gear 70 and the engagement of the second helical gear 64 drive greatly
Inclination angle conveying device 4 works, and high inclination-angle conveying device 4 is by third belt wheel 67, the first belt 68 and the 4th belt wheel 69 by power
It is transmitted to conveyor screw 3, power is forwarded to revolution grid type digger blade 1 by conveyor screw 3 by chain sprocket.
In work, cterpillar drive engine rear output shaft power is input to reduction box 60 by belt pulley and inputs
Axis, reduction box 60 drive spiral brush washer 11 by reduction box bevel gear 61, are transmitted with movable belt pulley by first pulley 48
Mechanism 10 works, and power is passed through driving wheel 42, third sprocket wheel 49, third chain 50 by 10 first pulley 48 of belt wheel transmission mechanism again
And the 4th sprocket wheel 36 pass to two-way vibrations separating mechanism 9, the second sprocket wheel 51 passes sequentially through belt wheel transmission mechanism, the first helical gear
70 and second helical gear 64 power of engine is forwarded to high inclination-angle conveying device 4, at the hydraulic stem 7 of hydraulic lifting system
When the state that promoted, the first helical gear 70 and the second helical gear 64 separation, power can not forward pass, when the hydraulic pressure of hydraulic lifting system
When bar 7 is in decline state, the first helical gear 70 and the engagement of the second helical gear 64 drive high inclination-angle conveying device 4 to work, and incline greatly
Angle conveying device 4 starts to be transported up water chestnut, and high inclination-angle conveying device 4 can pass through third belt wheel 67, the first belt the 68, the 4th again
Power is forwarded to conveyor screw 3 by belt wheel 69, and conveyor screw 3 is driven to rotate, and conveyor screw 3 can be driven back again by chain-wheel mechanism
Turn the work of grid type formula digger blade 1, starts to excavate water chestnut.
Crawler type water chestnut combined harvester of the present invention is primarily directed to the harvesting of water chestnut paddy field, using cterpillar drive
There is the advantage that contact area is big, grounding pressure is small, grounding pressure uniformity is good, adhesion property is good, paddy field work can be well adapted to
Make；Also, it is directed to paddy-field-working, revolution grid type digger blade can solve when water chestnut digger operation that hilling phenomenon is serious, work
Make the problems such as resistance is big, while can prevent water chestnut leakage from digging, reduces the damage to water chestnut；The direction vibration separator packet of use
It includes the rear throwing campaign to water chestnut to sieve with left and right, detaches more thorough, good separating effect than traditional unidirectional separator, pass through digging
The upturned soil that pick shovel enters in direction vibration separator includes mixture, stone and cauline leaf of soil and water chestnut etc., and water chestnut exists
When throwing movement after being done on sieve plate, the rasp bar on sieve plate can increase the frictional force between water chestnut and sieve plate to water chestnut
Effect and effect of impact are curried in generation, and when doing left and right on sieve plate and sieving, sieve plate generates vibration to water chestnut and makees water chestnut
With.The larger soil of water chestnut surface tackiness is removed with effect of vibration by the effect of currying of rasp bar, separation rate leads to up to 70~80%
The stone and cauline leaf in effect of impact removal mixture are crossed, separation rate reaches 90%, of the invention compared with common separation device
Direction vibration separator is combined by two kinds of disengaging movements, and separation is thorough, and reliable operation is small to the damage of water chestnut, is detaching
While water chestnut is conveyed backward, in favor of the rear further operating to water chestnut, can be disposed in water chestnut joint recovering device, increase
The separation rate and removing rate of big water chestnut and soil, liberate labour, reduce cost of labor；And spiral brush washer can be real simultaneously
It the cleaning of existing water chestnut and transports backward, spiral brush sifter has transfers to water chestnut and radially curries in the spiral brush washer of use
It acts on, rolling after keeping water chestnut oblique in filter mud net, cleaning is more thorough, and spiral brush sifter is arranged horizontal by angle, and water chestnut is certainly
It is rearwardly moved to from cleaning chain-drive section under the action of body weight component and spiral brush sifter transfers power, realizes continuous wash, clearly
It washes thoroughly, cleans rate up to 80%.Therefore, the present invention can disposably complete the work such as excavation, transport, separation, cleaning, packaging, and
It is little to the requirement of water source storage level, the time of water chestnut harvest is substantially reduced, efficiency of crop is improved, harvest process damages water chestnut
Hinder small, alleviates peasant's labor intensity, realize the intensive manufacture of water chestnut.
