Abstract
The utility model belongs to an induced draft simple selecting or threshing machine, principally adopting a transversal induced draft fan, the selecting fans (10), (11), (15), an induced draft adjusting plate (2), a sliding plate for grain (9), etc. The utility model is characterized in that the transversal induced draft fans and the threshing cylinder belong to one moving component namely the axial selecting fan fixed on the front shelf of the sliding plate for grain, an accompanying diagram is abridged general view for the utility model fixed on the threshing machine in the type of 5T-700A. The utility model has the major advantages of separating and selecting the grain, chaff and crushed straws in soil with moisture under the function of the induced draft and blowing, reducing the labor intensity of the operating personnel and the pollution of the operating personnel, simple structure and convenient repair.
Description
The utility model belongs to the simple and easy winnowing thresher of a kind of air draught type.
Now, the thresher technology is a kind of simple and easy thresher of comb formula of cutting in China rural area extensive use as " workers and peasants-700 type ", and agent pushes by artificial, feeding mouth has return air in various degree, seed is not cleaned: and for example " 5T-700A type " cuts the simple and easy thresher of comb formula, is on type bases such as workers and peasants-700 type, improves spout length angle, restriction threshing cylinder rotating speed (mA * 1200r/min), change the return air baffle shapes, emersion object, does not obtain separating in grain, broken straw clever shell; 5T-70 type finishing thresher for another example is to cut the comb threshing by traditional, and crop adds the belt automatic transport by artificial the propelling movement, and transmission mechanism adopts multistage V-belt to rotate, and straw shaker separates Lysimachia sikokiana, has sieve to clean.The common sufficient part of thresher of enumerating three types is that feeding mouth has return air, and operating personnel are subjected to the pollution of dust and clever shell.The existing portioned product time limit of first type thresher stops production; though second type has and improves but still have return air; and seed, clever shell, broken straw etc. do not separate; the third belongs to the type of recommend producing, this type from threshing, separate, clean, adopt traditional design method, technical do not have a new breakthrough; member is many, association is strong; structure is complicated, manufacturing cost is big, the price height, and the cost of repairs is big.
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of air draught type simple and easy winnowing thresher, and the major technique feature is: threshing cylinder and transverse air drafting fan are a moving component.Clean fan power by the threshing cylinder spindle drive.
The utility model is achieved through the following technical solutions, this device is cleaned fan (10) (11) (15) grain sliding plate (9) grain collecting chamber (8) by air draught adjustment plate (2) spoke dish fixed head (3) air draught blade (5) intermediate support (6) and is formed, transverse air-intake fan principle is adopted in air draught, air draught blade (5) number is between the 8-28 sheet, using rivet (12) to be riveted on spoke dish fixed head (3) and the intermediate support (6) respectively is assemblied in the threshing cylinder, be fixed on the middle pushing out ring of spoke dish (4) and threshing cylinder, belong to a moving component together with threshing cylinder, feeding mouth during threshing (1) produces negative pressure, and grass outlet produces malleation.Air mass flow is cleaned fan and is contained on grain sliding plate (9) forebay (7) by air draught adjustment plate (2) adjusting, air inlet through hollow shaft on the case.Clean the fan transmission by threshing cylinder main shaft output, adopt the V belt transmission, seed, clever shell, broken straw are separated under air draught and blowing effect power.Seed drops in the grain collecting chamber (8), by artificially collect, clever shell, broken stem straw discharge outside the body.Clean fan blast, blowing adjustable angle joint.
The utlity model has following advantage:
Simple in structure, easy to manufacture, air draught blade (5) and spoke dish fixed head (3) adopt whole riveted joint with intermediate support (6), be convenient to assembling, easy to use, different cultivars, the threshing of different humidity crop need not changed accessory, do not join power in addition, because the feeding mouth air draught reduces operating personnel's contamination by dust degree.Seed has alleviated labour intensity by cleaning.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof
The mark sequence number is expressed as follows respectively in the accompanying drawing, (1) feeding mouth, and plate (3) spoke dish fixed head, (4) spoke dish are adjusted in (2) air draught, (5) air draught blade, (6) intermediate support, (7) frame, (8) grain collecting chamber, (9) grain sliding plate, (10) clean fan drum.(11) clean fan propeller, (12) rivet, (13) intermediate support connection holes, (14) spoke dish fixed head connection holes, (15) clean fan pulley.
Fig. 1 is according to the utility model, and the embodiment duty generalized section of structure on 5T-700A type off line cleaned in the air draught of proposition.
Fig. 2 is a transverse air-intake fan principle schematic
Fig. 3 cleans the fan schematic diagram.
With reference to diagram the utility model is implemented to be described in detail as follows: the transverse air-intake width of blade is 0.8 times of a blade external diameter; the number of blade is 16; the blade type shape is antecurvature musical form; be linked to be integral body with spoke dish fixed head (3) intermediate support (6) with rivet (12); by intermediate support connection holes (13); spoke dish fixed head connection holes (14) is fixed by bolts in the 5T-700A type thresher drum with middle palm ring and spoke dish (4), and induced draught fan and threshing cylinder become one.Clean fan and be fixed on the frame (7), power is by the direct transmission of cylinder left end belt pulley.Former 5T-700A thresher critical piece feeding mouth (1) frame (7) roller assembly; the notch board assembly; constant Deng primary structure; operating position and method are constant; laterally air draught blade (5) is cleaned fan propeller (11) and is cleaned the making of fan drum (10) employing A3120 hot rolled plate, belt pulley (15) material HT20-40.
