Description
The utility model multifunctional agricultural screening machine is a kind of grain farmer's engineering goods, is applicable to all kinds of grains are cleaned.Screening can be carried out compound three grades of separation effectively, and have washing function concurrently.
At the vast rural area of China and numerous grain departments, often need sieve grain.Results such as wheat, general method is the wheat harvesting to be beaten grind the mixture that obtains wheat clothing wheat at present, traditional method is to utilize artificial lifting, and by natural wind with wheat clothing wheat separately, not only labour intensity is big but also must could production operation when wind is arranged for this.Productivity ratio is also very low.The general fan of indivedual local uses is arranged with generation wind-force, but use and inconvenience.In China grain farmer machinery production industry,, produced a kind of parabolic type winnowing machine for addressing this problem, be characterized in material is placed on the high-speed belt conveyor, by the inertia force that material obtains material is dished out, heavier material drops at a distance, and the low weight not plump paddy of chaff clothing is dropped on nearby.More than two kinds of methods a common shortcoming is arranged, be exactly that occupied ground is excessive, often cereal is sprinkling upon than on the large tracts of land, very uneconomical for small lot batch manufacture.In some grain shops of basic unit, before grain purchases are put in storage, need sieve grain, to remove grass-seed, impurity such as not plump paddy, the method that its custom adopts is a kind of movably old-fashioned hand wooden windmill, or the fixed windmill that drives by electric power, in these two kinds of methods, the former productivity ratio is low, the latter is limited to because of not moving producing, more than two kinds of methods also have a common shortcoming to be: the screening process of material in fact just carries out when material mouthful falls through the air channel at grain, also can only carry out the secondary separation to material when the material that falls sieve through the inclined-plane.
Task of the present utility model is to overcome above-mentioned existing in prior technology weak point, and provide a kind of grain sieving machine, this sieving machine can thoroughly solve above-mentioned artificial lifting, the various shortcoming of parabolic type winnowing machine and all kinds of windmills, can significantly improve productivity ratio, reduce work area, thereby the purpose of this utility model is to provide a kind of through improved multi-functional screening machine.
Technical solution of the present utility model is: a kind of multifunctional agricultural screening machine, comprise rotary screen, the inclined-plane sieve, aerofoil fan, quill shaft, transmission system, its special character is that described rotary screen is installed on the quill shaft of horizontal positioned, be provided with lifting blade and helix on the inwall of rotary screen, aerofoil fan is at an end of rotary screen, sky is enclosed within on the same axis, the inclined-plane sieve places the below of rotary screen, arrange along the cylinder tangential direction, transmission system is with motor, diesel engine or people's masterpiece motive power, be input on the power transmission shaft through V belt, be provided with a pulley concial disk and a pin gear on power transmission shaft, the aerofoil fan that power drives on the main shaft through the V-belt rotates, and has promptly formed an air channel in screen drum, pin gear drives the pin wheel that connects firmly at rotary screen one end, thereby rotary screen is rotated, main shaft a section in rotary screen be hollow and from opening wide on one side, on this section axle, be drilled with many radial holes.
The rotating speed of the rotary screen in the above-mentioned technical solution is chosen according to (0.76～0.78) * critical speed, so that material can slide along inwall, can under the effect of lifting blade material be kicked up again to be waterfall shape to fall; The air quantity of aerofoil fan can be regulated by the method that changes rotating speed, and the method that changes rotating speed is the V-belt transmission to be paid make buncher; The pin wheel pin tooth transmission of the working environment that relatively is suitable for winnowing is adopted in the transmission of transmission system afterbody, and also available chain replaces the pin wheel transmission in reality is implemented, so that simple in structure and reduce the cost; The screen cloth of shaft screen and inclined-plane sieve can be changed according to the granularity of different material.
The utility model will be illustrated more clearly in the accompanying drawing of the following example.
Accompanying drawing 1 is a profile of multifunctional agricultural screening machine.Being described as follows of each symbol among the figure:
1, prime mover; 2, power transmission shaft; 3, belt pulley;
4, speed governing vee-pulley; 5, pin gear; 6, handle;
7, little vee-pulley; 8, fan; 9, hopper;
10, pin wheel; 11, taper scraper-trough conveyer; 12, rotary screen;
13, quill shaft (main shaft); 14, inclined-plane sieve.
Multi-functional screening machine shown in the accompanying drawing 1, power passes to belt pulley 3 on the power transmission shaft 2 by prime mover motor or diesel engine 1, thereby driving axle 2 rotates, a speed governing belt wheel 4 and pin gear 5 are arranged on axle 2, belt wheel 4 links by the little vee-pulley 7 on belt and the aerofoil fan 8, drives fan 8 and rotates; Pin gear 5 and the pin wheel 10 that connects firmly on rotary screen 12 are meshed, driving shaft screen 12 rotates, part 7.8 connects firmly together, and sky is enclosed within on the main shaft 13, rotary screen 12 is packed on the main shaft 13, the left end of main shaft 13 is hollow for one section, on this section axle, be drilled with the radial hole of some, when material need wash, water pipe can be inserted the A place, hole of main shaft 13 left ends, water promptly evenly is sprayed in the rotary screen by the aperture on the axle, not having electricity or not having under the situation of diesel engine, can shake main shaft by the handle 6 that is located at main shaft 13 right-hand members, power will pass to pin gear 5 and 8 rotations of power transmission shaft 2 belt wheels 4 drive fans by pin wheel 10 this moment.4.7 laminated v-belt can be pulled down when not needing to dry.Rope need be twisted with the binding wheat straw with wheat straw toward contact in this thrashing floor for wheat, external rural area, so be provided with this function in this screening machine, promptly handle 6 is pulled down, and is screwed into a bolt in the aperture of axle head, can twist straw rope at motor or diesel engine during for prime mover.
The course of work of this screening machine is such: material falls through hopper 9, when passing through fan the place ahead, the light matter material promptly is blown out in the material, rest materials is in tapering part 11 slips shaft screen, one edge inboard wall of riddle drum slides, thrusted by spiral on one side, and kicked up by lifting blade, the chaff clothing that does not wherein blow off still can be blown at this moment, the material that slides along the sieve wall in wherein thick and fine granules leak down by mesh, fall on the inclined-plane sieve 14 and by the inclined-plane sieve it is separated into middle coarse fodder and fines, thick material is then outside screen drum left end discharge machine.
The utility model is implemented used material and is common material, and its machining manufacture is the common mechanical manufacture method.This machine can form a series according to the size of required output.
Comprehensive above embodiment as can be seen, the utility model has following advantage compared to existing technology:
1, owing to adopted fan and rotary screen simultaneously, can prolong the time and intensity that material is crossed wind and sieved.
2, employing blows out type and crosses wind, and the useless not plump paddy of chaff clothing is dropped at a distance, and useful material falls along compass screen surface, the floor space when having reduced work.
3, owing to adopted two layer screen, can carry out three grades of separation to material.
4, compass screen surface can be changed, and has enlarged the scope of application; Have three kinds of motive power input modes, guaranteed the possibility of using under the various conditions.
5, compact conformation, volume is little, easily mobile operating.
