Abstract
The utility model relates to a threshing machine for agricultural purposes, which has to blowers. An integral double-layer screen is arranged on a cleaning part. A cyclone separation recover is arranged on a rear blower. The utility model is characterized in that the integral double-layer screen can carry out acceleration grading and separation; the work efficiency of the utility model can be improved by one time compared with the existing threshing machine; the cyclone separation recover can recover crops covered in tail materials which are discharged so as to reduce crop loss. The utility model has the advantages of reasonable design, simple structure and convenient operation and maintenance. The utility model is a more complete and practical new agricultural machine.
Description
The utility model belongs to a kind of agricultural machinery.
Existing thresher is by power, threshing and clean part and form.Its deficiency is: cleans part and only is single sieve, and feeding more than, the compass screen surface body is little, cleans not as good as right, make thing section amass thick, spill-over, even stop up, influence work efficiency, not thorough because of sieving, make that to wrap grain in the tailing that is discharged from more, cause too many grain loss, cause the manpower waste again.Invented a kind of thresher in order to overcome above-mentioned deficiency.
The purpose of this utility model is that a kind of thresher will be provided, and it not only improves work efficiency, reduces grain loss, can concentrate recovery grain, and save time, the saving of labor.
The purpose of this utility model is achieved in that this device is equipped with two blower fans cleaning part, is provided with at the other end of blower fan (7) and roughly selects and selected double-deck sieve, last short time long.Upper sieve sieve aperture φ 18mm circular hole, lower floor's sieve aperture is 1.5 * 2.0mm oblong aperture, is provided with a cyclonic separation recover at another blower fan one end, it is by revolving branch and reclaiming two parts and form.Revolve and be divided into hollow taper type, an end of big mouthful welds at an angle of 90 with an end of connector, and an end of osculum overlaps with an end of soft circular collection bag, and the other end of collection bag scatters, and is to export.Operation is right, and tailing enters cyclone separator with the wind, becomes eddy flow because of wind is hampered, and the grain in the tailing is different because of proportion with assorted bits, separates voluntarily under eddy flow, enters collection bag through the frustum mouth.Under the tangent line effect of collection bag, eddy flow becomes laminar flow, forms tailing district and grain district, and to the collection bag exit, tailing flies at a distance, and grain is gone into bag nearby or landed, and finishes the purpose of recovery.
Owing to taked above-mentioned design, the utility model not only improves one times of work efficiency than present thresher, and has reduced the loss of grain, and the utility model is reasonable in design, and is simple in structure, and Operation and maintenance are convenient.
Below, the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is the structural map of the utility model thresher.
The utility model is by motor (1), belt pulley (2), material inlet (3), group tube (4), cylinder (5), blower fan (6), blower fan (7), cyclone separator (8), collection bag (9), eccentric wheel (10), support (11), double-deck frame (12), (13), notch board (14), discharging opening (15), discharging opening (16), put out cereal mouthful (17), axle (18), ratch formations such as (19).
Motor (1) and cylinder (5) connect with screw with axle (18), group tube (4) bottom is installed notch board (14) back and is connect with screw with blower fan (6), after axle (18) one ends are installed belt pulley (2), be fixed on (11) one on support, the other end passes group tube (4), blower fan (6), (7) are installed in support (11) other end, belt pulley (2) connects eccentric wheel (10) by belt, eccentric wheel (10) connects double deck screen (12), (13) with connecting rod, during work, reclaim three grades through threshing, double-deck screening, whirlwind and sort to scan and finish with terminal.
One-level sorts: goes up at cylinder (5) under the effect of ratch (19), and grain and straw after separating, outside straw return fan (6) the discharge machine, things such as grain fall from notch board (4).
Secondary is made and sorted: belt pulley (2) makes movable eccentric wheel (10) drivening rod mechanism, conjuncted double deck screen (12), (13) vibration, the grain that comes out from notch board (14) screening partly falls into upper sieve (13), screening, the grain part falls into lower screen (12) by φ 18mm sieve aperture, and remainder moves to blower fan (7) and locates, major part is inhaled into cyclone separator, fraction continues to move to the sieve end, and light thing such as chip is discharged from outside the machine through the mouth of putting out cereal, and grain partly continues to fall.
Three grades sort: fall into sieve (2) grain part by sieve (13), continue screening by sieve (12), straw end and earth are sieved into ground, grain partly moves to blower fan (7) in the sieve (12), straw above grain bits and wherein small part grain suck cyclone separator (8) by blower fan (7), be not inhaled into part and move to graduate from old-type opera school mouthful (16) and be discharged from, grain is discharged by put out cereal mouthful (17).
Scan: entered cyclone separator (8) from the part that conjuncted double deck screen (12), (13) suck as tailing by blower fan (7), wind is hampered into eddy flow in cyclone separator.Under cyclonic action, straw leaf bits separate because of the proportion difference voluntarily with grain in the tailing, after the frustum osculum enters resorption bag (9).Be subjected to the effect of tangent line in the collection bag, eddy flow changes over laminar flow, forms tailing district and grain district, and to reclaiming sack, at a distance, go into bag nearby or land by grain by wind for tailing, realizes the recovery of grain.
Claims (3)
1, a kind of thresher that is used for agricultural; it is characterized in that: this device is provided with two blower fans (6) (7) cleaning part; be equipped with at blower fan (7) one ends and revolve branch and to reclaim cyclonic separation recover dimerous (8), be provided with at the other end of blower fan (7) and roughly select and selected double-deck sieve (12) (13).
2, thresher as claimed in claim 1 is characterized in that: double-deck sieve (12) (13) is upward short long down, and the distance between two sieves (12) (13) is 80mm, the sieve aperture φ 18mm circular hole of sieve (13), and sieve (12) is 1.5 * 20.0mm oblong aperture.
3, thresher as claimed in claim 1; it is characterized in that; cyclonic separation recover (8) φ 500mm * φ 350mm * φ 640mm; also can suitably add and subtract according to the thresher model; recover (8) is hollow taper type; weld at an angle of 90 with connector (22) one ends big mouthful (20), osculum (21) and circular soft collection bag (9) one ends overlap joint.
