Abstract

The utility model relates to a miniature combine which is matched with a walking tractor and is used for the harvest of grain, and the utility model is composed of a horizontal type header arranged at the front part of the combine, an axial flow threshing device arranged at the middle part of the combine and a cleaning system arranged at the back-upper part of the combine, wherein the cleaning system is composed of a cyclone separating cylinder and an impurity sucking blower which are arranged at the left and the right sides of the combine; cutting stock of the horizontal type header is connected with a feed inlet of the axial flow threshing device through a conveying trough; an outlet of a material auger arranged at the bottom of the axial flow threshing device is provided with a winnower; an outlet of the winnower is communicated with an inlet of mixtures of the cyclone separating cylinder arranged at the same side as the winnower through a winnowing passage; an outlet of light impurity stock, which is arranged at the top of the cyclone separating cylinder, is connected with the impurity sucking blower through an impurity sucking pipeline; the impurity sucking pipeline is provided with a negative pressure regulating opening for regulating the effect of the impurity sucking blower on the cyclone separating cylinder, and then, the cleaning loss rate and the grain cleaning rate can be regulated. A machine frame of the miniature combine is matched with the walking tractor in an assembling mode, and power of each power part is provided by the walking tractor.

Description

A kind of miniature grain combine of and walking tractor matching

Technical field

The utility model relates to a kind of be used for grain harvest and miniature grain combine walking tractor matching, belongs to agricultural mechanical field.

Background technology

Existing combine harvester can be divided three classes: backpack, towed and self-propelled.Because existing type is excessive, can't finish the harvest operation of hills and patch cereal.And,, possess a considerable amount of hand tractors in the peasant household in hills and patch farming in the rural area.This machine is small, and maneuverability if be used, is developed suitable combine harvester, will can be good at addressing the above problem.

The utility model content

At the problems referred to above, the purpose of this utility model is to provide a kind of and miniature grain combine walking tractor matching, with harvesting, the threshing of once finishing hills or patch cereal with clean operation.

For achieving the above object, technical solution adopted in the utility model is: a kind of miniature combine harvester of and walking tractor matching, this miniature combine harvester is by the horizontal ceding of Taiwan of front portion, the axial threshing device at middle part and the cleaning and sorting system of upper back constitute, cleaning and sorting system by about the cyclone separating tube and the impurity adsorbing blower that are provided with constitute, the material cutting of the horizontal ceding of Taiwan links to each other by the spout of delivery chute with the axial threshing device, the outlet of the material screw feeder of axial threshing bottom of device is provided with winnow, the outlet of winnow is communicated with the compound inlet of the cyclone separating tube of homonymy installation by the passage of winnowing, the light impurity exit at cyclone separating tube top links to each other with impurity adsorbing blower by the gettering pipeline, the frame of miniature combine harvester and walking tractor matching assembling, the power of each power part is provided by hand tractor.

The gettering pipeline is provided with negative pressure and regulates mouth, is used to regulate the action intensity of impurity adsorbing blower to cyclone separating tube.

Miniature combine harvester of the present utility model is a mating power with 7.5～9kW hand tractor, and mobility is good, can once finish harvesting, the threshing of hills or patch cereal and clean operation.Experiment showed, that the utility model can guarantee harvesting efficiency 〉=1.5 mu/hour; Total losses≤1.5%; Grain cleaning rate 〉=98%.For general peasant household, under the situation that does not have very big financial difficulty, the miniature combine harvester of investment buying one playscript with stage directions utility model of having the ability fully not only can satisfy personally, and externally paid service kills two birds with one stone.In addition, because body of the present utility model layout is from front to back, constitutional balance, center of gravity is lower, combines one integrated mass with the hand tractor body, and operation is got up steadily, safety, and operation relatively is adapted at hills, rural area or fritter operation freely.

Embodiment

As Fig. 1, shown in Figure 2, the miniature grain combine of of the present utility model and walking tractor matching, the horizontal ceding of Taiwan by the front portion, the axial threshing device at middle part and the cleaning and sorting system of upper back constitute, cleaning and sorting system by about the cyclone separating tube 13 and the impurity adsorbing blower 15 that are provided with constitute, the material cutting of the horizontal ceding of Taiwan links to each other by the spout of delivery chute 5 and axial threshing device, the outlet of the material screw feeder 11 of axial threshing bottom of device is provided with winnow 12, the outlet of winnow is communicated with the compound inlet of the cyclone separating tube 13 of homonymy installation by the passage of winnowing, the light impurity exit at cyclone separating tube top links to each other with impurity adsorbing blower 15 by gettering pipeline 14, the frame of miniature combine harvester and walking tractor matching assembling, the power of each power part is provided by hand tractor.The gettering pipeline is provided with negative pressure and regulates mouth, is used to regulate the action intensity of 15 pairs of cyclone separating tubes 13 of impurity adsorbing blower.

The horizontal ceding of Taiwan is made up of cutter sweep 2, ceding of Taiwan body 3 and ceding of Taiwan screw feeder 4; The axial threshing device is made up of threshing body 6, notch board 7, threshing cylinder 8 and loam cake 9; Cleaning and sorting system is made up of cyclone separating tube 13, gettering pipeline 14 and impurity adsorbing blower 15.The configuration relation of complete machine and hand tractor is: dispose the horizontal ceding of Taiwan and axial threshing device in the dead ahead of hand tractor 17, at the rear of tractor configuration cleaning and sorting system.

During work, under the supporting role of straw shift wheel 1, finish cutting to crop by cutter sweep 2.Cereal after the cutting is swung to ceding of Taiwan body 3 under the lay effect of straw shift wheel 1, carried to ceding of Taiwan body one end by ceding of Taiwan screw feeder 4, delivers to the axial threshing device by delivery chute 5 again.The cereal that enters sheller unit is finished threshing under the synergy of threshing cylinder 8, notch board 7 and top cover 9, the crop stem after the threshing is outside straw outlet 10 discharge machines.Seed, disconnected fringe, clever chaff and short stem mixture fall to material screw feeder 11 through notch board 7, and push to winnow 12 by material screw feeder 11, the wheel of winnowing of winnow throws mixture to cyclone separating tube 13, impurity adsorbing blower 15 through gettering pipeline 14 with cyclone separating tube 13 in light foreign material in the mixture siphon away, and being discharged to the field, seed and disconnected fringe fall in the tanker 16 through the mouth 18 of putting out cereal.Gettering pipeline 14 is provided with negative pressure and regulates mouthfuls 19, by regulating mouthfuls 19 aperture regulating the action intensity of 15 pairs of cyclone separating tubes 13 of impurity adsorbing blower, and then regulates cleaning loss percentage and grain cleaning rate.
