CN2275329Y - Harvester mated with 12 horsepower walking tractor - Google Patents

Abstract

The utility model relates to a full feeding rice and wheat two-purpose combined harvester mated with a 12 horsepower walking tractor. Two handles of the walking tractor are removed, and a direction machine is used instead for controlling rear direction guiding wheels. An engine of the walking tractor is installed in displacement. A gap bridge mechanism is used for carrying out power transmission. The utility model provides double layer scissors for cutting cereal. The feeding quantity of stalks is reduced, and thus, the power consumption of transportation and threshing is reduced. At the same time, two rolls are used for threshing. The threshing performance is increased, and the loss of food is reduced. When a farm is slack, a harvesting apparatus can be removed, and the original functions of the walking tractor can be restored. The utility model has the advantages of one machine with multiple functions, low cost and lower farmers' burden. The utility model provides an ideal tool to farmers having walking tractors for harvesting at farms.

Description

Grain header with 12 horsepowers of walking tractor matching

The utility model relates to agricultural mechanical field, particularly a kind of structure of the full feeding rice and wheat dual-purpose combination grain header that can match with 12 horsepowers of hand tractors.

Combine is an agricultural equipment crucial in the current agricultural production, it is three kinds on a large, medium and small type, large and medium-sized combine is because investment is big, expense is high, peasant household buys seldom, though and minicomputer early has manufacturer production but be half and feed formula, to rice wheat two ripe crop area bad adaptability, and complex structure, fault is many, operation is inconvenient, human pilot labour intensity is big, therefore peasant household not too welcomes, and a large amount of hand tractor in rural area leaves unused during the busy farming season certainly, can not give full play to its effect.

The purpose of this utility model is: design a kind of and 12 horsepowers of full feeding rice and wheat dual-purpose combination grain headers that hand machine is supporting, to improve the availability of existing 12 horsepowers of hand machines, realize a tractor serves several purposes, reduce the investment that peasant household purchases large and medium-sized combine, reduce agriculture production cost, reduce farmer's burdens.

The purpose of this utility model is achieved in that the displacement of 12 horsepowers of hand tractor engines is installed to fuselage right side front wheel rear portion; unload former handgrip; repacking direction machine control back directive wheel; utilize gearbox that fore-stock and after-poppet are installed; the ceding of Taiwan is connected with fore-stock; thresher is installed on after-poppet; the delivery chute front end and the ceding of Taiwan are joined; rear end and thresher join; the power that 12 horsepower engines send is through the distribution that is used as power of the gap bridge belt pulley of frame on gearbox; wherein a part of power drives clutch; through gearbox power is defeated by ceding of Taiwan transmission mechanism; drive up and down two-layer scissors reciprocating motion and finish cutting operation, another part passes to axle and thresher belt pulley on the delivery chute through the gap bridge belt pulley, finishes threshing operations.For overcoming 12 horsepowers of contradictions that are short of power; design upper and lower two-layer scissors the rice wheat is made cutting twice; upper strata scissors cut rice wheat head head part for the first time; the above cane of lower floor's scissors cut rice wheat stubble second time; cane lay field does not enter thresher; alleviated the load of thresher, and thresher is designed to the twin-roll structure, improved the threshing effect.

Provide accompanying drawing of the present utility model

Among the figure: 1; 12 horsepower diesel engines; 2 hand tractor gearboxes; 3 lower floor's scissors; 4 upper strata scissors; 5 nearside dividers; 6 straw shift wheels; 7 cedings of Taiwan; 8 delivery chutes; 9 threshings gap bridge axle; 10 carry the axle of passing a bridge; axle on 11 delivery chutes; 12 blower fans; 13 threshers; 14 threshing cylinders; 15 secondary threshing cylinders; 16 concave grates; 17 grass-removing wheels; 18 adjustable plates; 19 go out paddy stirs cage; 20 back directive wheels; 21 after-poppets; 22 direction machines; 23 power take-offs; 24 fore-stocks; 25; 27; 28; 29; 30 are the gap bridge belt pulley; 26 clutches; 31 power output V belt; 32 eccentric wheels; connecting rod on 33; 34; 35 rocking arms; 36 lower links

Briefly introduce the utility model technology contents and implementation method below in conjunction with accompanying drawing:

As seen from the figure; 12 horsepower engines 1 are mounted to fuselage right side front wheel rear portion do displacement; unload hand steered original two handgrips; direction machine 22 control back directive wheels 20 in the repacking; utilize gearbox 2 that fore-stock 24 and after-poppet 21 are installed; fore-stock 24 connects the ceding of Taiwan 7; thresher 13 is installed on the after-poppet 21; delivery chute 8 front ends are connected with the ceding of Taiwan 7; rear portion and thresher join; installing one on fore-stock 24 passes a bridge; belt pulley 25; 27; 28; 29; 30 bear various transmission of power respectively; the power that 12 horsepower engines 1 send; through gap bridge belt pulley 27; 28 do a power distribution; wherein a part drives clutch 26 by gap bridge belt pulley 28; through gearbox 2; power is exported through power take-off 23; through V belt 31; drive eccentric wheel 32 on the gap bridge 29; eccentric wheel 32 connects connecting rods 33 and 36, drives rocking arm 34 and 35, make the upper strata cut 4 and lower floor's scissors 3 do straight reciprocating motion; another part power is through gap bridge belt pulley 27; 25; 10 drive on the delivery chute 8 threshing cylinder 14 that axle 11 and thresher belt pulley 14 make thresher 13 respectively; threshing operations is finished in 15 rotations of secondary threshing cylinder.

During this machine farm work: nearside divider 5 will cut the inside and outside cereal in district separately; the cereal that will be entered left and right sides nearside divider 5 by straw shift wheel 6 is dialled to upper strata scissors 4; grain ear part by upper strata scissors 4 cutting-out cereal; fall into the ceding of Taiwan; bottom cereal cane is by lower floor's scissors 3; carry out secondary cut; the discharging field; grain ear enters delivery chute 8 from the ceding of Taiwan 7; enter thresher 13 through conveyer belt and do threshing for the first time by a thresher drum 14; secondary cylinder 15 takes off again; the fringe bar of taking off is by outside the grass-removing wheel 17 discharge machines, and the grain of taking off is fallen out paddy and stirred cage 19, flows into grain sack by going out the grain mouth that connects that paddy stirs cage 19 places; deviate from assorted surplus in the cereal and blow out outside the machine, thereby once finish harvesting by blower fan 12; carry; threshing; separate; clean; the integration of operation overall process of pack.

The utility model utilizes 12 horsepowers of hand tractors to be power, design double-deck scissors cereal is carried out cutting twice, reduced the cane feed quantity, alleviated the power consumption of conveying and threshing, use the twin-roll threshing, improved threshing performance, reduced the loss of grain, adopt direction machine control trailing wheel guide frame, increased the flexibility of operation.

The utility model can be widely used in the repacking of 12 horsepowers of hand tractors, per hour can gather in 1.5 mu, and pull down reaping apparatus during slack season and still can be used as hand tractor and be engaged in rural area transportation, be that peasant household is used for the desirable instrument that the rice wheat harvest is cut.
