Description
Technical field
The utility model relates to the thresher machine of crops, specifically a kind of husker sheller.
Background technology
The existing a kind of husker sheller that more generally uses; its primary structure is; there is a rotating shaft to pass in the threshing cavity that bolter on the frame and case surround; one end of threshing cavity is provided with discharging opening; the upper end of case is connected to feeding hopper; rotating shaft is positioned on the outer axle head of threshing cavity is equipped with belt pulley; be positioned at the grain threshing roller that band threshing tooth and discharge pawl are housed on the shaft part of threshing cavity; be connected in the below that striker plate on the frame and marker board are trapped among bolter; the space of the two forms discharge gate; below discharge gate, be provided with a fan shaft parallel, on fan shaft, be connected with some blades with discharge gate.Its operation principle is, corn ear is entered in the threshing cavity by feeding hopper and by threshing tooth on the grain threshing roller of rotation and discharge pawl the iblet bump is reached crowded stranding the with the hands, iblet and other light weight sundries are discharged by discharge gate by behind the bolter, when they fall, the wind-force that produces by the blade on the fan shaft of rotation separates iblet and other light weight sundries, and is discharged by the discharging opening that grain threshing roller is delivered to threshing cavity one end by the foreign material such as corncob of bolter.
Above-mentioned husker sheller exists following deficiency: the wind-force that iblet of being discharged by discharge gate and light weight sundries are produced by the fan shaft blade separately after, light weight sundries is directly blowed to the work-yard of device external, operator's working environment is relatively poor, and light weight sundries can not directly be collected; When the light weight sundries that flies upward falls, have part and fall into the iblet heap, the separating effect of iblet and light weight sundries is undesirable; Fan shaft and on blade working the time vibration bigger, the two is yielding, service life is short.
Goal of the invention
The purpose of this utility model is to provide a kind of good work environment, seed and light weight sundries good separating effect, light weight sundries to collect husker sheller easily.
For achieving the above object, the utility model adopts following scheme:
Bolter on the frame and case surround a threshing cavity, one end of bolter is provided with discharging opening, the upper end of case is connected to feeding hopper, threshing cavity is passed in the rotating shaft that is loaded on the frame, belt pulley is housed in the rotating shaft, rotating shaft is positioned on the shaft part of threshing cavity is equipped with grain threshing roller, be installed with some threshing teeth and discharge pawl on the grain threshing roller, be connected in the below that striker plate on the frame and marker board are trapped among bolter, the space of the two forms discharge gate, below marker board, be provided with a wind sucting tube, the sidepiece of wind sucting tube is established a bar shaped inlet scoop that communicates with its inner chamber, the lower end of this inlet scoop and marker board is adjacent, the end sealing of wind sucting tube, the air inlet of the other end and an induced-draught fan joins, and induced-draught fan is installed on the frame.
By such scheme as seen; rotating shaft and induced-draught fan are by the power set transmission; when making this husker sheller be in duty; corn ear is sent in the threshing cavity from feeding hopper; through threshing tooth on the grain threshing roller and discharge pawl bump and after squeezing stranding; iblet separates with corncob, and iblet and other light weight sundries are not discharged by the discharging opening that grain threshing roller is delivered to threshing cavity one end by the foreign material such as corncob of bolter by being discharged by discharge gate behind the bolter.Because induced-draught fan makes and produces negative pressure in the wind sucting tube, when iblet and other light weight sundries fell inlet scoop through wind sucting tube by discharge gate, light weight sundries was inhaled into wind sucting tube, and iblet then flows to ground smoothly, and iblet is separated with light weight sundries.The light weight sundries that enters wind sucting tube enters induced-draught fan and is discharged by its air outlet from the air inlet of induced-draught fan.Air outlet at induced-draught fan connects with dust bag, the light weight sundries of discharging can be collected.
The utility model to iblet, corncob, light weight sundries three separate effective, light weight sundries is collected convenient, has improved operator's working environment widely, and it also has compact conformation, rationally, the characteristics that operate steadily.

The left view of Fig. 2 Fig. 1.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
Referring to Fig. 1
Referring to Fig. 2
One end of threshing cavity 12 is provided with discharging opening 27, discharging opening 27 be connected to one the band mesh 26 ' discharge groove 26.Rotating shaft 6 is loaded on the frame 1 by pair of bearing 25, and grain threshing roller 7 is loaded on rotating shaft 6 and is positioned on the shaft part of threshing cavity 12.Grain threshing roller 7 is provided with some threshing teeth 9 and discharge pawl 8, and each discharge pawl 8 arrangement on grain threshing roller 7 is linear in the shape of a spiral, and grain threshing roller 7 can be sent foreign material such as corncob by discharge pawl 8 when rotated from discharging opening 27.More than be prior art.The air inlet of one end sealing, the other end and the induced-draught fan 2 of wind sucting tube 17 joins, and the inlet scoop 16 of wind sucting tube 17 sidepieces is bar shaped, and an end of wind sucting tube 17 sealings is fixed on the frame 1.One with the affixed support 24 of frame 1 on bearing block 23 is housed, the main shaft 22 of induced-draught fan 2 is contained on this bearing block 23, the air outlet 28 of induced-draught fan 2 bottoms is frame 1 dorsad.One belt pulley 21 is housed on the main shaft 22 of induced-draught fan 2, and an end of rotating shaft 6 is equipped with two belt pulleys 18,19, and 21 of belt pulleys on belt pulley 19 in the rotating shaft 6 and induced-draught fan 2 main shafts 22 are connected with belt 20.
By Fig. 1; Fig. 2 as seen; by power-equipment by 18 drive shafts 6 of the belt pulley in the rotating shaft 6; grain threshing roller 7 is rotated; rotating shaft 6 is by another belt pulley 19 on it and the belt pulley 21 on belt 20 transmission induced-draught fans 2 main shafts 22; make induced-draught fan 2 obtain power; make this husker sheller be in duty; corn ear is sent in the threshing cavity 12 from feeding hopper 10; through threshing tooth 9 on the grain threshing roller 7 and discharge pawl 8 bumps and after squeezing stranding; iblet separates with corncob; iblet and other light weight sundries are discharged by discharge gate 14 by bolter 5 backs, are not delivered to 27 mouthfuls of discharges of discharging of threshing cavity 12 1 ends by the discharge pawl 8 on the grain threshing roller 7 by the foreign material such as corncob of bolter 5.Because induced-draught fan 2 makes and produces negative pressure in the wind sucting tube 17, when iblet and other light weight sundries are fallen to passing through the inlet scoop 16 of wind sucting tubes 17 by discharge gate 14, light weight sundries is inhaled into wind sucting tube 17, and iblet then flows to ground smoothly, and iblet is separated with light weight sundries.The light weight sundries that enters wind sucting tube 17 enters induced-draught fan 2 and is discharged by its air outlet 28 from the air inlet of induced-draught fan 2.Air outlet 28 at induced-draught fan connects with dust bag, the light weight sundries of discharging can be collected.
