Description

Thresher

The utility model relates to a kind of thresher, in particular for the thresher of crops such as paddy and wheat, beans.

Existing thresher generally is made up of frame, charging aperture, threshing cylinder, concave grate, grass outlet etc.; material enters the back and carries out threshing by cylinder and concave grate relative motion; straw is discharged by grass outlet; for seed is separated with the standing grain bits; the thresher that has has been set up devices such as cleaning blower fan, seed elevator; one or two cleaning unit is arranged in it; the mote separating mechanism makes seed separate with the standing grain bits; though this class threshing function is once separated straw, seed and standing grain bits three, its complex structure is huge, cost is higher.

The purpose of this utility model is the deficiency that overcomes prior art for this reason, and a kind of thresher is provided, and it can not only once be finished threshing, clean the double freight operations operation, and straw, seed and standing grain bits three is separated, and simple in structure, compact, manufacturing cost is lower.

The technical scheme that realizes the utility model purpose is a kind of thresher; comprise frame; be divided into the charging aperture and the grass outlet at frame two ends; be fixed with the cover plate that has disposed stock guide on the frame; in the cover plate is concave grate and threshing cylinder; cylinder is by the power belt wheel drive; frame lower is a grain-collecting groove; the screw rod of collection grain elevator effect has been arranged in it, and its special character is that the below of concave grate is provided with the filter screen vibrating device, and cleaning fan is installed in the frame outside; be positioned at the below of feed inlet end concave grate; drum shaft drives the blower fan rotation by belt pulley, and blower fan has fan shroud outward, and the concave grate bottom of discharge port end is provided with the bucket that keeps out the wind.

And the filter screen in the filter screen vibrating device links to each other with frame by linkage, is fixed with the vibration supporting device in the middle of the filter screen of grass outlet end.

And the cage plate of vibration supporting device is packed on the filter screen, and cramp bar one end is placed in the circular hole of cage plate, and the other end is a sleeve, and the bottom of cramp bar links to each other with frame.

And fan shroud is provided with shutter.

And the groove face of grain-collecting groove afterbody is provided with fish scale shape baffle plate.

The cleaning fan of this thresher is installed in the frame outside; be positioned at the below of feed inlet end concave grate; when the mixture of seed and standing grain bits falls; most of standing grain bits are blown out outside the machine by blower fan; seed and a small amount of standing grain bits drop on the filter screen of filter screen vibrating device; the sleeve of cramp bar bottom places the screw rod side in the filter screen vibrating device; rotation along with screw rod; on the cramp bar; move down, make filter screen make periodic vibration, seed is shaken fall in the grain-collecting groove; realize that seed separates fully with the standing grain bits; owing to be provided with in the machine cleaning unit and mote separating mechanism be set, so complete machine structure is simple; compactness, manufacturing cost are also lower.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the front view of filter screen vibrating device.

As Fig. 1; frame shown in Figure 2 10 tops are fixed with the cover plate 1 that has disposed stock guide 2; charging aperture 18 and grass outlet 3 lay respectively at the rear and front end of frame 10; in the cover plate 1 is concave grate 17 and threshing cylinder 16; cylinder 16 is driven by the belt pulley 4 that electromotor or diesel engine drive; frame 10 bottoms are grain-collecting groove 21; the screw rod 9 that the effect of collection grain elevator has been arranged in it; cleaning fan is installed in frame 10 outsides; be positioned at the below of feed inlet end concave grate 17; drum shaft 15 is by belt pulley 12; 14 drive blower fan 11 rotations; the blower fan 11 outer fan shrouds 13 that have on the frame of being installed in; fan shroud 13 is provided with shutter; can be used for regulating air quantity; the below of concave grate 17 is a filter screen vibrating device 5; filter screen in the filter screen vibrating device 5 23 links to each other with frame 10 by linkage 22 as shown in Figure 3; in the middle of the filter screen of grass outlet end, be fixed with vibration supporting device 25; the cage plate 24 of supporting device 25 is packed on the filter screen 23; cramp bar 7 one ends are placed in the circular hole of cage plate 24; the other end is a sleeve 8; and cramp bar 7 lower ends and frame 10 are affixed; sleeve 8 is positioned at the side of screw rod 9 blades; when screw rod 9 rotates; cramp bar 7 with on; move down; make filter screen 23 make periodic vibration; in the course of work; material at first carries out threshing by the relative motion of concave grate 17 and threshing cylinder 16; straw is discharged by grass outlet 3; seed material and standing grain bits fall; most of standing grain bits are blown out outside the machine from impurity discharging port 6 by blower fan 11 when falling; confusing the standing grain bits for fear of seed is blown; can regulate air quantity by shutter; also can keep out the wind simultaneously and struggle against 19 in grass outlet end concave grate 17 bottoms installation one; remaining then a small amount of standing grain bits and seed material are fallen on the filter screen 23; vibration along with filter screen 23; seed falls into grain-collecting groove 21 by filter screen; in order to prevent outside the seed outflow machine; the groove face of grain-collecting groove 21 afterbodys is provided with fish scale shape baffle plate 20; last seed is transported to lifter 26 by the screw rod in the grain-collecting groove 21 9; by lifter 26 it is sent from seed outlet 27, so just realized straw; seed; the standing grain bits separate fully.
