Abstract
The utility model discloses a threshing and winnowing device which is characterized in that blower blades are arranged on one end plate at the rear end of an impeller, an annular baffle plate is arranged in the front of the end plate, and the annular baffle plate and a machine casing form a blower casing; the rotation of the impeller drives the blower blades to rotate, an exhaust air pipe is composed of a machine casing and a sliding plate, the front end is connected with the blower casing, the trend of an air passage of the exhaust air pipe is from top to bottom, turns 90DEG, passes through the lower part of the sliding plate, then turns 90DEG and reaches an adjustable separating sliding plate, and a wind power adjusting plate is arranged on wall of the exhaust air pipe; a wind power guiding plate is arranged in the air passage, the adjustable separating sliding plate is arranged at an outlet of the air passage to adapt to the requirements of various crops and crops with different moisture capacity.
Description
The utility model relates to thresher machine, more precisely relates to the cleaning plant of thresher.
The thresher of prior art is mainly by power section, and the threshing part is cleaned part, running part, and supporting part is formed.Power section comprises motor, driving-belt, protective cover; Threshing partly comprises impeller, concave grate, guide plate; Supporting part comprises frame, casing; Running part comprises driving wheel, driven pulley, V-belt; Clean part and comprise blower fan, front and back slide plate, air channel.During work, motor rotates by the driving-belt impeller, and crop is by the feeding of impeller front end, and crop cooperates rubbing through impeller with casing, seed, clever shell, broken tangerines etc. are under effects such as impeller centrifugal force, fall through concave grate, clean through cleaning plant, the tangerine grass is discharged behind pusher side or machine.The cleaning plant of above-mentioned thresher is made up of two parts; both running parts and clean part; blower fan is located at the tail skid below; motor power drives blower fan by running part and rotates generation wind-force, and wind-force carries out selection by winnowing to fall seed, clever shell, the broken tangerine of gathering through the front and back slide plate through concave grate again, and kernel weight is big; continue to drop to discharging opening; and foreign material such as clever shell, broken tangerine are in light weight, under the wind-force effect, discharge in the air channel of front slide and lower casing formation.
The weak point of above-mentioned thresher is the cleaning plant complex structure, and volume is big, and the thresher volume is increased, and power consumption is big, cost is high.
The purpose of this utility model provides a kind of simple in structure, and volume is little, and power consumption is low, the cleaning plant of the finishing thresher that efficient is high.
Scheme of the present utility model is that fan propeller is located on the end plate of impeller rear end, ring baffle is housed before end plate, ring baffle and casing constitute Fan casing, and wheel rotation drives fan propeller and rotates, and produce wind-force, wind-force blows out in the air channel of exhaust duct, to through the seed of slide plate polymerization, clever shell, broken tangerine etc. carry out selection by winnowing, and the air channel trend of exhaust duct is earlier from top to bottom, transfer axially process below slide plate to, transfer warp-wise again to regulating separated skateboard.For effect is cleaned in raising, on wind path wall, be provided with the wind-force adjuster, in the air channel, be provided with the wind-force guide plate, be provided with at ducting outlet and can regulate separated skateboard.
The drawing explanation:
Fig. 1 is the utility model structural representation,
Fig. 2 is the left view of the utility model Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment).
With reference to shown in Figure 1, motor 5 is contained in the frame 4, the power of motor 5 passes to belt pulley 10 through V belt 7, belt pulley 10 rotates through axis 16 impeller 9, the threshing blade 15 of impeller 9 front ends cooperates with casing 14, crops from feed hopper 17 feeding are carried out threshing, and the tangerine grass is through being installed in separation tooth plate 13 on the impeller 9 outside straw outlet is discharged casing 14.Seed, clever shell, broken tangerine etc. fall through concave grate 1.With reference to shown in Figure 1, before impeller 9 rear end end plates 20, be provided with ring baffle 8, ring baffle 8 constitutes Fan casing with casing 14, and fan propeller 12 is in Fan casing, and fan propeller 12 is fixed on the end plate 20 of impeller 9 rear ends.Fan propeller 12 is square, and with reference to shown in Figure 2, there is a right-angle side fan propeller 12 windward sides.
With reference to Fig. 1, shown in Figure 2, exhaust duct 18 is made of casing 14 and slide plate 19, and exhaust duct 18 front ends and Fan casing connection connect, the air channel of exhaust duct 18 is earlier from top to bottom, above motor 5, transfer to axially, behind slide plate 19 belows, transfer to more radially to regulating separated skateboard 22.See that before machine air channel trend is, earlier downwards, 90 ° turn to after forward, behind slide plate 19 belows, change 90 ° again and turn to the machine left.With reference to Fig. 1, shown in Figure 2, on exhaust duct 18 walls, be provided with wind-force adjustable plate 21, mainly be to reduce wind-force.In the air channel, be provided with a wind-force guide plate, be fixed in the air channel, wind-force is evenly distributed.Be equipped with one and can regulate separated skateboard 22 on ducting outlet, can regulate separated skateboard 22 sides is triangle, can regulate separated skateboard and goes out open height and adapt to and clean plurality of cereals by regulating.As threshing rape and wheat, during the threshing rape, seed and clever shell weight differ little, outlet should be heightened, seed is not blown, and when taking off wheat, because of seed and clever shell, broken tangerine weight differ greatly, outlet should be turned down, during with a kind of crop, wet different in threshing because of doing, also can meet the needs of by adjusting open height.Sequence number 3 is a discharge bucket among the figure, and 6 is protective cover, and 11 is bearing block.
The utlity model has following advantage: 1, cleaning plant is simple in structure, and volume is little, thereby has reduced Complete machine weight; 2, reduce the transmission device of blower fan, reduced power loss, improved power utilization Rate.
