Abstract

The utility model relates to an air-suction-type automatic grain elevator which is an automatic grain elevator to be used for matching with a threshing machine. The grain from the threshing machine enters a connection bucket (1), and then enters a separation box (11) through a conveyor tube (2), and the light impurity can be extracted out of the air-suction-type automatic grain elevator through an air suction blower (4), and the heavy impurity and grain open a removable cover plate (10) to enter a vibration sieve (8), and a first sieve (9) can clean the grass section and large soil block. A second sieve (12) can clean the small soil block and the separated grain is placed in bags through a grain outlet (13). Small soil block falls into a sieve base board and is extracted through an exhaust tube (17). The grain has high purity after the air separation and two separations. The air-suction-type automatic grain elevator has low cost and simple structure and is very suitable for countryside to use.

Description

The automatic winnowing machine of air draught type

The utility model relates to the automatic winnowing machine of a kind of air draught type, is the match winnowing machine of the cleaned cereal that uses of a kind of and thresing machine.

Harvesting in existing technology, thresing machine is varied.In order to clean seed after the threshing, all kinds of winnowing threshers, finishing thresher are arranged again.This type of technology is also a lot of in the file of the Decree of Patent Office of China.For example: " the simple and easy winnowing thresher of air draught type ", " the twin-roll manpower is thrashed, the dual-purpose machine of wind valley " (CN2084283U), " axial flow winnowing thresher " (CN2138883Y), " two roller rescreener " (CN2139772Y) etc.These thresing machines have, and only to have flailing action, heavy winnowing to be operated in the rural area merely a lot of local or undertaken by manpower.Some thresing machine has cleans function, but substantially only has a kind of function, and the dust that for example only has the cleaner granule of screening function is difficult for cleaning out.And the big soil block of the thresing machine particle that has only the selection by winnowing function is difficult for being removed by selection by winnowing.

The purpose of this utility model provides the automatic winnowing machine that ped, dust and the saving of soil block grass in a kind of and the matching used grain clearly of thresing machine can be cleared out of.

Scheme of the present utility model is as follows: the grain after utilizing induced-draught fan with threshing and heavily assorted, gently assorted automatic transport utilizes induced-draught fan will gently mix and grain, heavy assorted separating in separator box.The vibratory sieve that two roads tilt is set in device.Big assorted as grass joint, the soil blocks etc. of first road with grain with in heavily mixing sift out, and second road sifts out grain, and little assorted as not plump paddy, little soil particle that particle diameter in heavily mixing is little sift out the back by outside the induced-draught fan discharge machine.Big assorted outlet, grain outlet, little assorted outlet are set respectively simultaneously.Make through the clean grain after selection by winnowing and the twice screening and flow in the bag automatically.And cereal does not land, clean and convenient.

The utility model can with the supporting use of all kinds of thresing machines.Grain automatic transport after threshing, clean automatically.And screening, selection by winnowing combination, that cleans is clean, and the grain high purity reaches the standard of delivering tax grain to the state.Both can exempt manual this heavy manual labor of winnowing, and can make near unlikely the stirring up a cloud of dust in workplace (thresing machine) again, grass joint, ail are flown upward over the sky, have reduced environmental pollution.And simple in structure, cost is low, is very suitable for promoting the use of in vast rural area.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1 is a structure chart of the present utility model.

Connect the below that bucket (1) is seated in thresing machine, the cereal after the threshing drops and connects in the bucket (1) at this.Because the effect of induced-draught fan (4), cereal enters in the separator box (11) of frame (5) top through carrier pipe (2).The effect of separator box (11) is with tiny dust, careless bits and cereal, heavy assorted separation.Dust, grass bits are called light assorted.There is a removable cover (10) below of separator box (11), the function of this cover plate be when the cereal in the separator box and heavily assorted when reaching constant weight this cover plate open.This cover plate is still closed when cereal and heavily assorted weight are in above-mentioned weight.In cereal and the heavily assorted vibratory sieve (8) that drops down onto the separator box below.Vibratory sieve is established the sieve that two roads tilt.Support by fagging (6) and spring (7).Big assorted i.e. grass during first road sieve (9) is heavily mixed what is called is mixed, big grogs sifts out.Outside outlet (15) discharge machine.Secondary screen (12), little assorted with what is called in heavily assorted is that not plump paddy, ped, ail etc. are sieved to down in one base plate (13) via outside (16) the discharge machine of outlet.The clean cereal that secondary screen (12) sifts out is discharged via going out the mouth of a valley (13).Go out under the mouth of a valley (13) to put bag, get final product automatic bagging.Gently mixing that other is tiny just enters induced-draught fan (4) via air channel (19) after outside the discharge machine of exhaust passage (17) enter separator box (11) with grain after.Motor (18), blower fan (3) drive induced-draught fan and vibratory sieve (8) vibration by transmission.Whole process makes grain through automatic transport, selection by winnowing and twice screening, automatic bagging, and with the supporting use of thresing machine, the work of cleaning after the threshing is also finished.
