Description

A kind of suspension type small combine

The utility model relates to improved combine, particularly a kind of suspension type small combine.

Existing baby combine mainly is made of following several parts.Power set, reaping apparatus, middle conveying plant, sheller unit, separator and collection grain device.As by name " a kind of hand suspension type small combine ", its patent No. is 98226265.5 to be wherein a kind of, and the deficiency that such grain header in use has has: 1. through performance is not good, because of they have only rubber wheel and two kinds of running gears of iron tyre.When working in wetland, its through performance is relatively poor.2. operating personnel influence operation because of present position lower (follow behind grain header and walk, perhaps on the tail wheel chair) working region to the front often is difficult to see clearly.3. the pneumatic separator effect is relatively poor, and percentage of impurity is still higher in the cereal.More 4. the grain header that has double cutter, its structure is not compact, needs two cover drive units to drive.

The purpose of this utility model is to propose that a kind of through performance is good, operating personnel's clear visual field, cereal percentage of impurity are low, the suspension type small combine of compact conformation.

Can realize the purpose of this utility model by following technical proposals: a kind of suspension type small combine, it is by constituting as the hand tractor (removing handrail) of power set and the combine harvester that hangs on it.Combine harvester comprises: reaping apparatus, middle conveying plant, sheller unit, separator, collection grain device is characterized in that:

A. its running gear also comprises creeper undercarriage except that rubber wheel and iron tyre;

B. be provided with a driver's seat above the diesel engine of hand tractor, operating mechanism is arranged in the place ahead, bottom of driver's seat;

C. the left end at the cylinder shaft of sheller unit is equipped with the centrifugal blower that moves about;

D. the levels cutter in the reaping apparatus connects respectively with the last bottom of a pendulum fork, and the pendulum fork connects with crank, and crank is contained in cereal conveying screw conveyor shaft left side end anyhow.

Effect of the present utility model is: 1. its through performance is strong, and this is that it has been equipped with rubber wheel, iron tyre and three kinds of running gears of crawler belt.Therefore, no matter its nonirrigated farmland, paddy field and wetland all can be worked preferably.2. owing to established the higher driver's seat in position, thereby make operating personnel can clearly see the operation area of front clearly, harvesting efficiency is improved, and control member all is positioned on the place ahead of seat bottom, centralized control has improved accuracy and the flexibility handled.3. at the left end place of cylinder shaft device centrifugal blower, 1. make pneumatic separator more compact; 2. improved blast, made the selection by winnowing better effects if, the cereal percentage of impurity reduces.4. double-cutting knife only by the single drive mechanism that pendulum is pitched and crank constitutes, simplifies the structure, and has improved the reliability of work.

Below in conjunction with accompanying drawing the utility model is further set forth

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model parts transmission schematic diagram;

Fig. 3 is the schematic diagram (broken section) at centrifugal blower device place in the utility model;

Fig. 4 is a creeper undercarriage schematic diagram in the utility model.

Referring to accompanying drawing 1, the utility model mainly carries screw feeder 4, vertical cereal to carry screw feeder 14, operating mechanism 5, driver's seat 6, diesel engine 11, running gear 16 to constitute by straw shift wheel 1, upper strata cutter 8, lower floor's cutter 10, ceding of Taiwan screw feeder 7, threshing cylinder 3, horizontal cereal.One end of upper strata cutter 8 and lower floor's cutter 10 respectively with movable connection of pendulum fork 9 upper and lower pendulum, pendulum fork 9 connects with the crank activity that is contained in horizontal cereal conveying screw feeder 4 ends.

Referring to accompanying drawing 2, the drive connection between the utility model parts is: diesel engine 11 outputting powers are to clutch 12, and the function one of clutch 12 is to drive running gear by the chassis gearbox; The 2nd, drive grain header operative clutch 13.Two power of operative clutch 13 outputs: the one, drive threshing cylinder 3 and horizontal cereal and carry screw feeder 4; The 2nd, drive the centrifugal blower 2 that moves about on threshing cylinder, horizontal cereal carries 4 left sides of screw feeder that two groups of sprocket wheels and a crank are housed, and sprocket wheel drives ceding of Taiwan screw feeder 7 respectively and vertical cereal promotes screw feeder 14.Crank drives upper cutter knife 8 by the pendulum fork and following cutter 10, ceding of Taiwan screw feeder 7 drive straw shift wheel 1 by belt pulley.

Referring to accompanying drawing 3: centrifugal blower 2 is contained in the left end of 3 of threshing cylinders with the attitude of moving about, wind is by the left end input of tube, overflow to right-hand member, paddy and foreign material in the threshing tube, fall by notch board 15, in the process that falls, the wind of centrifugal blower 2 inputs blows out right output port with foreign material, and cereal then falls into horizontal cereal and carries screw feeder 4.

Referring to accompanying drawing 4: driving wheel 17 is contained on the semiaxis of hand tractor chassis, and directive wheel 18,19 of bogie wheels are bearing on the frame of diesel engine 11, and crawler belt 20 can be elastomeric material and also can be metal material.

Claims (1)

1, a kind of suspension type small combine, it is by constituting as the hand tractor (removing handrail) of power set and the combine harvester that hangs on it, combine harvester comprises: reaping apparatus, middle conveying plant, sheller unit, separator and collection grain device is characterized in that:
