Abstract

The utility model discloses a high efficiency rice harvester, composed of a threshing device and a rice cutting device. The threshing device is in front of the rice cutting device. The front end of the threshing device is welded with a row of comb steel bundles which are composed of circle steel wires. An interval between the steel wires is not greater than three millimeters. A threshing cylinder is arranged on the threshing device, and a lateral conveyer belt and a longitudinal conveyer belt are arranged below the threshing device. The high efficiency rice harvester first finishes threshing actions, and then cuts straws. The high efficiency rice harvester has the advantages of quick threshing, easy straw cutting off, high work efficiency, and convenient operation and maintenance.

Description

High efficiency rice harvester

The utility model relates to a kind of agricultural machinery that is used to gather in paddy rice, belongs to the farm machinery class.

The outlet of agricultural is mechanization; but it is big to carry out the mechanical work difficulty in paddy field; the harvesting of paddy rice is a hang-up especially; there are many technical schemes to mention this problem for this reason; for example; Chinese patent CN2113597U number about proposing installation swather and thresher on hand tractor in " combine "; after the rice bar is cut off by swather; be transported on the transport platform of threshing; under the effect of rice-pulling tooth and carrier chain, deliver to threshing on the threshing cylinder that has aerofoil fan; selected, this grain header operation easier is big; inefficiency, machinery is out of order easily.

Task of the present utility model is that a kind of novel rice harvester will be provided, and it can carry out threshing operation earlier, and then cuts off the rice bar, high efficiency, and threshing is rapidly and to cut off the rice bar easy, compact mechanical structure, the harvesting process realizes automation.

Task of the present utility model is to finish in such a way, the steel that the YIPAISHU shape is housed on the front end face of threshing device is pricked, it is to weld on end face with circular steel wire that steel is pricked, the gap of every steel wire is not more than 3 millimeters, set up a threshing cylinder above the threshing device, a transverse onveyer is arranged below cylinder, traveling bed of a termination of this conveyer belt, grain can be delivered to sampler from threshing device like this, delivering to vessel after grain process secondary threshing processing and fan are selected transports back, rice cutting machine is being followed in the threshing device back, it is made up of two blades up and down, and bottom knife is fixed, and last section moves back and forth under main shaft draws, form shearing force the rice bar of threshing is cut off, by a vertical transport band rice bar is taken away again and be discharged into the field.

Below in conjunction with accompanying drawing the utility model is further elaborated.

Fig. 1 is a complete machine structure figure of the present utility model.

Fig. 2 is vertical transport belt shape figure of the present utility model.

Fig. 3 is a separating mechanism schematic diagram of the present utility model.

As can be seen from Figure 1, this novel grain header has power (1) and gear (2), can drive the motion of front-wheel (3) and trailing wheel (4), main shaft (5) locates to be equipped with a clutch (6), one end of main shaft (5) has a tooth sector (7), its traction is gone up section (8) and is made shearing motion back and forth, on main shaft (5), also be equipped with gear (9), (10), (11), (12) and (13), they drive threshing cylinder (14) respectively, vertical transport band (15), fan (16), sampler (17) and traveling bed (18) running, tooth sector (7) also draws transverse onveyer (19) motion, bottom knife (20) is fixed, adorning the steel of YIPAISHU shape on the front end of threshing device (21) and pricking (22), it is to weld upper edge in threshing device (21) with circular steel wire that steel is pricked (22), steel wire gap each other is not more than 3 millimeters, set up the threshing cylinder (14) of a circle above the threshing device (21), below the cylinder (14) transverse onveyer (19), one termination of transverse onveyer (19) a traveling bed (18), and traveling bed (18) stretches out threshing device (21) to sampler (17).Threshing device (21) back is rice cutting machine (24), and rice cutting machine (24) is made up of cutter (8) and bottom knife (20).

Fig. 2 is the shape figure of the vertical transport band (15) on the rice cutting machine (24), the vertical steel nail (25) of two rows is housed on conveyer belt (15), and Fig. 3 is the threshing schematic diagram of circular threshing cylinder (14) and comb shape steel bundle (22), evenly distributed profile of tooth steel wire (26) is arranged on the cylinder (14), the afterbody that steel is pricked (22) is pointed, and be inclined upwardly a little, it is move toward one another that steel wire (26) is pricked (22) with steel.

When grain header under the promotion of power (1), front and back wheel (3), (4) begin to travel forward, the comb shape steel of threshing device (21) front end is pricked (22) can intert into rice bar, steel wire (26) on the threshing cylinder (14) is got to the spike of rice on the rice bar afterbody, part paddy is come off, because steel is pricked (22) at interval less than paddy, and be upwards skewed a little, the grain that comes off can only be pricked (22) along steel and drop on the transverse onveyer (19), steel is pricked (22) and is moved forward, remaining paddy is subjected to squeeze rubbing with the hands and dropping one after another on the rice bar, last rice bar is pricked (22) from steel and is broken away from, at this moment rice cutting machine (24) is caught up with and, and its cutter (a 8) rice bar that ceaselessly moves back and forth is sheared, and then takes away the rice bar of having cut off by vertical transport band (15).Transverse onveyer (19) is delivered to the grain that drops on threshing device (21) on the traveling bed (18), and traveling bed (18) is delivered to sampler (17) to grain again and is carried out the secondary shelling and handle, fan (16) blows foreign material and jejune grain off, from outlet output, finish the harvesting task then.
