Abstract
The utility model provides a mechanical thresher for rice and wheat, which mainly consists of a body, a threshing roller, a threshing screen, a collecting hopper, a screw conveying roll and a fan roll. The screw conveying roll and the fan roll are mounted at the bottom of the collecting hopper, and the body is provided with a straw outlet, a chopped straw blow-out port and a finished product discharge pipe which respectively form three independent delivery passages. The mechanical thresher for rice and wheat has the advantages that firstly, by means of initiating a winnowing cleaning structure that 'the fan roll and the chopped straw blow-out port are assembled at the bottom of the collecting hopper', the thresher can realize winnowing cleaning operation synchronously so as to obtain pure finished products, secondarily, by the aid of a screening discharge mechanism of 'an eccentric traction vibrating screen' arranged at the straw outlet, straw can be output smoothly, grains in straw can be recovered, and precious grain resource can be saved. In addition, the mechanical thresher has the advantages of simple structure, low manufacturing cost, small volume, light weight, strong operation mobility and fine straw separating effect, and is the first choice for upgrade and update of household agricultural instruments for farmers.
Description
Technical field:
The utility model relates to a kind of grain harvest machine, belongs to the technical field of agricultural machinery, specifically a kind of motor-driven rice-wheat thresher, and it is specially adapted to water paddy and wheat class grain farmer plant is carried out the motor-driven operation of place harvest-seed extraction.
Background technology:
Along with the high speed development of China's agricultural machinery cause, greatly quickened the process of Tendency of Agricultural Machinery in Chinaization, at present, all generally adopt large-scale combine to carry out harvest operation in the rice wheat place of production of flat area.But in vast rice wheat producing region, hills, most of peasant family is still and adopts manual mode to carry out the harvest-seed extraction operation, and this operating type labour intensity is big, production efficiency is low, will seriously restrict the development process of this area's agricultural economy.For addressing this problem, the small-sized rice-wheat thresher that use in mountain area, a collection of suitable hills has been produced in the disconnected mutually research and development of agricultural machinery producer, and low, the motor-driven operation of its price in light weight is strong, is subjected to the favor of hills farmers in mountain area family.According to market survey: still there is the improved defective of some needs in actual use in existing small-sized rice-wheat thresher product; particularly it can not be clean with the forage sorting when carrying out on-the-spot harvest-seed extraction operation; the peasant also need carry out the processing operation that selection by winnowing separates broken forage once more behind harvest-seed extraction could obtain pure paddy or wheat finished product; not only increase peasant's work load, also increased the hauling operation expense of grain harvest.This is the improved place of existing rice-wheat thresher product needed, this also just the utility model want the problem that solves.
The utility model content:
The purpose of this utility model is intended to overcome the deficiencies in the prior art part; propose a kind of motor-driven rice-wheat thresher that selection by winnowing is separated forage that can carry out synchronously in harvest-seed extraction, it has, and simple and direct, the motor-driven transaction capabilities of structure is strong, easy for operation, forage good separating effect, the pure remarkable advantage of finished product quality.
The utility model is achieved by the following technical solution:
A kind of motor-driven rice-wheat thresher; it comprises body, engine, grain threshing roller, thrashing screen and receiving hopper; said thrashing screen, receiving hopper are installed on the bottom of grain threshing roller; body is provided with the forage delivery outlet; it is characterized in that: at forage output Oral appliances vibratory sieve is arranged, receiving hopper bottom equipped spiral conveying roller, fan roller and broken careless blow-off outlet.It designs forage delivery outlet, broken careless blow-off outlet and discharge nozzle in one, can carry out the processing operation that selection by winnowing is blown down broken grass synchronously, " output forage ", " blowing out broken grass " and " finished product is thrown and sent " three logistics are taken their own roads in an orderly manner, have the advantage of production efficiency height, broken careless good separating effect.
The utility model also has following technical characterictic:
Be provided with the thin careless swash plate of one group of guiding forage delivery outlet at the body inwall, can dredge the forage that produces in the threshing course to the forage delivery outlet and it is exported outside the body swimmingly.
Equipped eccentric wheel on the main shaft of grain threshing roller, eccentric connecting rod is connected in the draw bar of vibratory sieve, and the roller that is fitted to vibratory sieve places and connects dish, and the chute that connects dish is connected with receiving hopper.Can draw vibratory sieve by eccentric mechanism and carry out double vibrations, when being screened, forage forms the effect of outside propelling movement, can push forage exports outside the body by the forage delivery outlet swimmingly, can farthest reclaim grain residual in the forage again, grain after sieving will be recycled in the receiving hopper by the chute that connects dish, this to the resource of saving food, accomplish that Every grain should be sent to the granary and increase good harvest, increase the peasant economy income positive effect is all arranged.
Said connecting rod is connected by adjusting nut with draw bar, can connect draw bar easily and regulate its drawing length, and the service behaviour of improving the vibratory sieve double vibrations is had certain effect.
A tail end that connects material of equipped spiral conveying roller is connected and installed with discharge nozzle, and the material casting plate that is fitted to the spiral roll shaft is positioned at the tube that connects material.Can push to a tail end that connects material by paddy or the wheat finished product of spiral conveying roller after, throw along discharge nozzle by the material casting plate again and send output paddy or wheat finished product, be convenient to the finished product pack greatly the selection by winnowing weeding.
Be arranged with one group of threshing tooth on the grain threshing roller surface according to spiral distribution, the control helical angle is 35 ° of 15 ∽, and splendid Lysimachia sikokiana and threshing operations effect are arranged.
The utility model is compared with prior art has following advantage:
1, it has initiated the careless mechanism that filters out by " eccentric wheel traction vibratory sieve ", can constantly push outside the forage output body, can farthest reclaim the grain that residues in the forage again, to the resource of saving food, increasing farmers' income all has positive effect.
2, its selection by winnowing of having initiated " the equipped fan roller in receiving hopper bottom, broken careless blow-off outlet " is removed grass structure, selection by winnowing is removed and is mixed broken careless shred in paddy or wheat synchronously, pure finished product pushes to tail end by the spiral conveying roller, throws to send through discharge nozzle again and expects that pack gets final product.
3, the utility model designs " vibratory sieve-forage delivery outlet ", " fan roller-broken careless blow-off outlet " and " discharge nozzle is sent in spiral conveying roller-throwing " three logistics corridors in one dexterously, can carry out selection by winnowing weeding operation synchronously during harvest-seed extraction at the scene, " forage output ", " broken grass blows out " and " finished product discharging " are taken their own roads in an orderly manner, can enhance productivity, alleviate peasant's labour intensity effectively, promote product quality.
4, simple in structure, the volume of the utility model small and exquisite in light weight, manufacturing cost is low, has that strong, the broken careless good separating effect of reliable, motor-driven transaction capabilities, finished product quality are pure, the distinguishing feature of long service life.
