Description

Small-sized rice/wheat combine

The utility model relates to the equipment of a kind of rice wheat combining.

At present traditional self-propelled rice/wheat combine since threshing and conveying mechanism separate, thereby make that it exists that volume is big, shortcoming such as Heavy Weight, efficient are low, particularly because volume is big, Heavy Weight, make its in the mountain area, the hills use is restricted greatly.

Known some small-sized harvester for both rice and wheat, though overcome above-mentioned part shortcoming, as Chinese patent application 95237352, though volume is little, in light weight, harvesting speed is slow, can not work continuously, so this product is not promoted in actual use as yet.

The purpose of this utility model will provide enough that a kind of volume is little, in light weight, efficient is high, cost is low, carrying need not special-purpose tractor road, be applicable to the Plain, the rice/wheat combine in the large, medium and small plot of mountain area, different regions, hills.

The purpose of this utility model is achieved in that by regulating shear height, make the rice wheat of differing heights enter threshing cavity, successively before, during and after carry out threshing on three threshing cylinders, when the fringe head moves on to last threshing cylinder, rice wheat root is just cut off, then at power, three threshing cylinders that grain header advances with go out straw after discharging threshing under the rod drum effect.Thereby saved the ceding of Taiwan screw feeder and the conveyer belt of traditional grain header, reduced volume, alleviated weight.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a profile front view of the present utility model.

Fig. 3 is a profile rearview of the present utility model.

Fig. 4 is a profile vertical view of the present utility model.

Fig. 5 is a transmission system sketch of the present utility model.

In the described structural representation of Fig. 1, nearside divider [1] will cut the inside and outside crop in district separately, and straw shift wheel [2] repeatedly hits threshing entering crop between left and right sides nearside divider [1] through guide plate [33] guide threshing cylinder [5] on three threshing cylinders.When crop arrived last threshing cylinder, cutter [3] cut off crop root, power, threshing cylinder [5] that grain header advances and go out rod drum [7] act under outside the discharge machine.The grain of taking off under the effect of vibratory sieve rake [6], separate and with the grain rake to the rear portion, through carrying screw feeder [8] horizontal feed, through promoting screw feeder [10] vertical-lift, drop into grain sack then again to connecing tanker [11].On cutter [3] top a cutter backplate [23] is arranged, can protect cutter and prevent that grain from leaking outside.The supporting of whole grain header is finished by two front vehicle wheels [4] and two rear wheels [9] with walking.All power is provided by diesel engine [12].

Describe the transmission principle of this utility model below again in detail in conjunction with Fig. 2, Fig. 3, Fig. 4, Fig. 5.

When clutch [15] when closing, diesel engine [12] slows down transmission of power to going out on the rod drum [7] through small belt pulley [13] and big belt pulley [14], when going out rod drum [7] rotation, front axle through minor sprocket [16] and hinge wheel [18] deceleration drive threshing cylinder [5] rotates again, the rear axle of threshing cylinder [5] drives through sprocket wheel [17], [20], the jackshaft of threshing cylinder [5] is through gear pair [32] driving, and threshing is worked in the time of three axles of realization threshing cylinder [5]; Vibratory sieve rake [6] power is carried out the cereal separation and harrows the work of sending through gear pair [31] transmission by the rear axle of threshing cylinder [5]; Carry screw feeder [8] power to transmit the work of carrying cereal through sprocket wheel [19], [21] by the jackshaft of threshing cylinder [5]; Promoting screw feeder [10] power realizes the synchronous transport that promotes screw feeder [10] and carry screw feeder [8] and promotes cereal to the work that connects tanker [11] through gear pair [30] transmission.

In above mechanism under the work, threshing, separation, the rake that can satisfy cereal send, carries, promotes, pack and straw are discharged the outer associated working of machine.

When clutch [29] when closing, front axle, the gear pair [32] of diesel engine [12] power through going out rod drum [7], threshing cylinder [5] is delivered on the power transmission shaft [22], the work that rice pulling wheel [2] power slows down and carries out pulling, holds up standing grain through eccentric small belt pulley [28] and big belt pulley [25]; Cutter [3] power is driven by eccentric small belt pulley [28], and the cutter that drives cutter [3] through centering block [24] transmission carries out cutting work; Rear wheel [9] power is through minor sprocket [27] and hinge wheel [26] deceleration rear wheel [9] walking.

In above all mechanisms under the work, can satisfy grain header walking, divide standing grain, pulling, hold up standing grain, threshing, cutting, cereal separate, rake send, carry, promote, pack and straw are discharged the outer associated working of machine.
