The combine harvester is characterized in that a vertical double-deck cutting table and a crops-head feeding structure are adopted, and an operating system is a handle with multifunction. The double-deck cutting table is hung at the right side of a tractor, and a distance is left between the upper and lower cutting tables in the horizontal direction for the convenience of double-deck harvesting; the vertical height of cutting stubble can be adjusted. The utility model which has the advantages of reasonable configuration, compact structure, flexible operation, convenient operation, energy saving, convenient assembly and disassembly, and high operation rate of machinery is suitable for the harvesting of wheat at the plots.

Description

The combine that a kind of small tractor is supporting

The present invention relates to a kind of small-size multifunction agricultural harvesting machinery, particularly a kind of baby combine of suitable northern small size wheat harvesting.

Existing combine mainly by the thresher of single ceding of Taiwan, civilian bar or spike-tooth single structure, form by delivery chute, operating mechanism.This grain header volume is big, the cost height.Because adopt full feeding structure, required power is big, also is not suitable for the operation of fritter field.

For addressing this problem, China has designed in south a kind of and baby combine walking tractor matching, but this grain header only is fit to the harvesting paddy rice, be not suitable for getting wheat, and efficient is low.

Purpose of the present invention is to overcome above-mentioned weak point in the prior art, and the wheat harvesting of a kind of suitable fritter field is provided, flexible operation adopts the double-deck ceding of Taiwan, reduces the horsepower loss, easy accessibility, the small-size multifunction harvest machinery that operation rate of machinery is high.

Task of the present invention is finished by following measure, in the double-deck ceding of Taiwan up and down of the positive suspension in the place ahead of 15 horsepowers of tractor with small four wheels vertical and horizontal.Lower cutting table adopts standing header to place the front lower place of tractor, finishes the cutting of cane.Upper header adopts the horizontal ceding of Taiwan to place the front upper place of tractor, finishes branch standing grain and standing grain head cutting operation.Delivery chute places the right side of tractor; thresher places on the after-poppet; threshing cylinder adopts civilian bar, spike-tooth segmentation mixing axial flow structure; selected air flow cleaning mechanism simultaneously for use, connect grain platform and be designed to the contractible type activity and connect the lower left that grain platform places tractor.The operating mechanism of this machine: separate control stick, the gear dead man is fixed on the lower end of the same handle, places tractor workbench left side.

Solution of the present invention can be illustrated with following drawings and Examples.

Fig. 1 is the supporting combine generalized section of small tractor that proposes according to the present invention.

Fig. 2 is a two cutting tables structural representation up and down of the present invention.

With reference to accompanying drawing, a dead ahead that is suspended on tractor 9 by lower cutting table on the vertical and horizontal of four connecting rods, 26 chute types connection.On the horizontal upper header 22 nearside divider 1 is housed, rice pulling wheel 3, last cutter 2 and upper header screw feeder 4, vertical lower cutting table is equipped with down cutter 5 respectively, conveyer belt 6, this nested structure all adopts hydraulic lifting, has made full use of the hydraulic system of tractor.For ease of the bilayer harvesting, vertical lower cutting table 25 is located at the back lower place of horizontal upper header 22, makes the lower cutting table front and back that certain distance be arranged.The delivery chute 20 of this machine is positioned at the right side of tractor; top is connected thresher feeding mouth place by driving wheel; the bottom rides over upper header delivery port place; thresher is connected the rear side of tractor by after-poppet 11; by adopting civilian bar; spike-tooth segmentation mixing axial-flow thresher cylinder 18, compositions such as notch board 19, grain flinging device 17, clear grain tube 16.The 12nd, the collapsible grain platform that connects.

The last lower cutting table of this machine can move up and down cutting stubble and the distance of cutting down between the stubble on changing by hanger bracket 7, and to cut batch minimum under the control be 75 millimeters.

The operation principle of this machine is: nearside divider 1 will cut the inside and outside crop in district separately; rice pulling wheel 3 pulls out upwards cutter 2 to the crop standing grain head part that enters between the nearside divider of the left and right sides; cutter is at crop jugulation cane; the crop standing grain head part of cutting off; under the effect of deadweight and tractor pace and rice pulling wheel 3, swing to horizontal upper header 22; deliver to the porch of ceding of Taiwan right side delivery chute 20 again by upper header screw feeder 4; pull out under the effect of tooth and carrier chain 21 rake teeths in the screw feeder feeding; crop standing grain head part is sent into thresher through delivery chute and is carried out threshing; divide high and clean; under the civilian bar of thresher drum 18 and spike-tooth effect, make circular motion and move axially; shift to the left side by the right side of cylinder; crop standing grain head is in moving process; be subjected to the strike of threshing cylinder; curry with notch board 19 on gentle repeatedly stranding the with the hands and threshing; grain falls through friend's checkerwork cell of notch board; be sent to grain flinging device 17 by screw feeder; throw to clear grain tube 16 by grain flinging device again; under the air-flow effect of fan 15; assorted surplus part is by clear grain tube top sucking-off; grain is directly discharged from the bottom under the effect of centrifugal force and gravity, is regained by pack into gunnysack 13 of collapsible grain platform 12 at last.

Meanwhile, vertical lower cutting table 25 is also carrying out the cutting work of remaining cane, delivers to the tractor left side by the cane that following cutter 5 is cut off under the effect of lower cutting table self conveyer belt 6, and lay is in the face of land.

The present invention has following advantage compared to existing technology; Machine is small and exquisite, flexibly, and adaptability By force, owing to adopt the two cutting tables structure, it is low to cut down stubble, and cutting height is adjustable up and down, has improved The collection rate of cane. Owing to feed crop standing grain head part, thresing machine adopts again civilian bar simultaneously, nail Tooth mixing drum and air flow cleaning structure have reduced kinetic equation loss, have saved the energy, and complete machine is established The meter compact conformation, configuration is reasonable, and in light weight, cost is low, owing to adopt piggy-back structure, tears open Dress is convenient, has improved the utilization rate of tractor, in current economic system reform land contract situation Lower, this machine is welcome by peasant household deeply.
