Abstract
The utility model relates to a rice thresher which is composed of a threshing mechanism and a material feeding mechanism. The threshing mechanism thereof is composed of two lines of row wheels which are mutually parallel. Each line of the row wheels are made of a set of shafts which are arranged on the machine frame parallelly and equidistantly, and the shafts with needle-shaped claws on surfaces are driven by worm gears. The opposite side of each of the two lines of row wheels is respectively provided with a baffle, and the needle-shaped claws extend out of the bores of the battles. The material feeding mechanism thereof is made of two conveying rubber belts capable of clamping rice straws, and the conveying rubber belts are arranged on the upper part of the two lines of row wheels. The rice thresher has the advantages of no rice grain and dust flying during threshing, no damage to rice grain, high threshing efficiency, etc.
Description
The utility model relates to agricultural tool, particularly a kind of paddy-eliminator.
Existing paddy-eliminator; adopt drum-type structure; promptly have on the outer surface of cylinder of hole some pin pawls are installed one; during operation; take rice bundle root by staff, spike of rice is taken dropped on the outer surface of cylinder, cylinder is high speed rotating under power drives; its pin pawl under the strip, is finished rice threshing with the grain of rice from the straw.There is following shortcoming in this paddy-eliminator when using: the one, because cylinder centrifugal force when high speed rotating is very big, make the grain of rice that comes off on cylinder and dust and chip to flying upward all round, and cause operating environment extremely abominable; The 2nd, to lean on during operation and manually ceaselessly stir rice bundle the grain of rice is purified, labour intensity is big, the straw that comes off simultaneously is also as easy as rolling off a log to be sucked in the tube from the cylinder space, cause and twine axle, must often clean, so threshing efficiency is low, general every thresher is equipped with 20 people's operations, and one hour can only threshing about 500 kilograms; The 3rd, the grain of rice taken off part (reaching as high as 15%) falls into cylinder inside when rotating with tube owing to clash into mutually and make its damage, form the broken shell crackle, the circuitous humid air of this paddy easily suction goes mouldy, be difficult for storing, as being used as seed rice, plantation back president goes out bum " wind rice ", directly causes the paddy rice underproduction.
The purpose of this utility model be to overcome the shortcoming of above-mentioned existing paddy-eliminator and do not have that the grain of rice and dust and chip fly upward when a kind of threshing is provided, threshing efficiency height, the injury-free paddy-eliminator of the grain of rice.
The paddy-eliminator that the utility model provides adopts plane formula threshing mode, is made of separating mechanism and feed mechanism.Its separating mechanism is made of the two row row wheels that are parallel to each other, every row row wheel is by one group of parallel equidistant is installed on the frame, the surface has interlaced arrangement pin pawl, be made of the axle of worm and gear transmission, the relative side of two row row wheels is separately installed with dividing plate, has on the dividing plate for row's wheel and rotates the exsertile hole of hour hands pawl; Its feed mechanism is made of the two slat gum V-belts that are installed in upper rack, and before and after this rubber V-belt and the outside is supported by rack-mounted sheave, and the inboard is supported by rack-mounted two groups of pulleys that have elastic support.
The embodiment that provides below in conjunction with accompanying drawing is further described structure of the present utility model.
Fig. 1 is the schematic perspective view of the utility model paddy-eliminator;
Fig. 2 is the schematic perspective view of single-row row's wheel among Fig. 1;
Fig. 3 is the side diagrammatic sketch of single-row row's wheel;
Fig. 4 is the vertical view of two row row wheels;
Fig. 5 is the schematic diagram of feed mechanism;
Fig. 6 is row's wheel transmission schematic diagram;
Fig. 7 is a feed mechanism transmission schematic diagram.
In conjunction with Fig. 1 to Fig. 7; this paddy-eliminator is got up its component packages by two removable casings 1; two row row wheels are made of five axles 3 that are installed on the frame 2, the surface has seven and eight pairs of pin pawls 4 respectively respectively; pin pawl length on every axle increases progressively from front to back along axle; its length that is positioned at front end is less than 1/2nd of lateral shaft spacing; its length that is positioned at the rear end is greater than 1/2nd of lateral shaft spacing; it is arranged and forms crisscross up and down state, overlooks visible anterior pin claw type and becomes triangular form material feeding mouth.The two tanks opposed inside is a dividing plate 9, its corresponding every pair of pin pawl has hole 10, dividing plate is installed near axle, the pin pawl is stretched out as far as possible, the feed mechanism that is made of two slat gum V-belts 7 is installed at upper rack, this rear and front end, V-belt and the outside are by rack-mounted sheave 5,6 and 11 supports, wherein preceding sheave 5 is a fixed pulley, the edge has for hanging the acupuncture 14 that straw is used, back sheave 6 has the drive of worm gear for the bottom, two groups of pulleys 8 by square travel(l)ing rest 12 controls that are with spring 13 that cotton is installed on the upper rack crossbeam in two V-belts support, and it is adjacent to when zero load mutually, have when carrying to clamp material.The transmission system of this machine is: motor (or diesel engine) 15 drives an axle that is positioned at the lower end by belt and belt pulley 16 and rotates, this axle drives vertical worm screw 19 by worm gear 17 and rotates, this worm screw drives this row axle along the speed rotation together of same direction by four worm gears 18 that are installed in respectively on other four axles again, this worm screw also drives horizontal worm screw 24 by the worm gear 20 that is installed in its top and rotates, this horizontal worm screw again behind two by the above-mentioned feeding of worm gear drives V-belt sheave 6 rotate, horizontal worm screw also drives the vertical worm screw 22 of another roots by another worm gear 21, and relatively rotates synchronously with the previous column axle by this row axle of five worm gears, 23 drives that is installed on another row axle.Each arrow is represented transmission direction among the figure.
The utility model paddy-eliminator can come design size according to the size of rice bundle; desirable 200 millimeter of distance together of two dividing plates; 700 millimeters of machine total heights; long 800 millimeters of front and back; the pin pawl can be made of No. 10 steel wires; insert admittedly on axle, the noise when alleviating threshing can be done baffle surface the weakening material and handle.
The paddy-eliminator that the utility model provides; as long as give last power; two row row wheels and feeding V-belt are that synchronous same-speed rotates; rice is tied between root feeding feed mechanism front end two sheaves, and the V-belt clamps the straw root under the resiliency supported pulley action automatically, and moves backward; the bottom spike of rice is in company with in the Road narrows that enter the formation of two dividing plates; the pin pawl that rotates stretches out from the dividing plate hole, and rice is tied certainly combing outside to inside a time, and the grain of rice is combed.Owing to be the plane threshing, no centrifugal action adds dividing plate again and stops, the grain of rice, dust and chip can only be fallen, and flies upward nowhere, thereby has improved operating environment greatly.Directly fall after the grain of rice comes off, be not subjected to violent bump, can injured broken shell.This machine replaces manual feeding with automatic feed mechanism, and labour intensity alleviates, and does not need frequent shutdown midway; so threshing efficiency improves greatly; every machine configuration three to five people, but about 2500 kilograms of threshings in a hour are 15 to 20 times of existing cylinder sheller efficient.
The utility model if with the supporting use of the Automatic sieve that has blowing device, can be with threshing, sieve and blow off once and finish.This machine is because volume is little, in light weight, and both adjustable point was installed and used, and also can be installed on the hand tractor in farm work.
