Abstract
The utility model discloses an eccentric rice-and-wheat threshing case, which comprises a threshing roller, a belt pulley, a front sieve, a bottom sieve, a grain blocking plate and a top plate. The threshing roller is connected in a case body through a transmission shaft and is provided with teeth, the belt pulley is arranged at one end of the outside of the case body and is used for power input, the front sieve and the bottom sieve are respectively arranged right ahead and below the threshing roller with the teeth, the grain blocking plate is arranged on the back of the case body, the top plate is arranged on the top of the case body, the other end of the transmission shaft opposite to the end of the belt pulley is provided with an eccentric shaft, and the eccentric shaft is connected with a front sieve connecting rod which can rotate along with the transmission shaft to drive the front sieve to move up and down. With the structure, the utility model has the advantages of completely delivering straws out of the threshing case or a straw outlet, reducing the chips in grains or wheat, reducing the labor intensity, saving the energy, and also reducing the use cost.
Description
Technical field
The utility model relates to the rice-wheat threshing case, particularly a kind of eccentric type rice-wheat threshing case.
Background technology
Along with development of social productivity, miniature agricultural is popularized gradually with machinery, and hilly country miniature rice-wheat thresher is particularly universal in China.Semi-automatic rice-wheat thresher in the market generally is made up of actuating unit, threshing case and appearance grain vessel.The threshing case generally is connected band tooth threshing cylinder in the casing and the outer belt pulley for the power input of casing by turning cylinder, and the fore worker that is arranged on band tooth threshing cylinder dead ahead and below becomes with end screen banks.Use the thresher of prior art threshing case need so improve peasant's threshing operating efficiency, but still have a lot of problems: short and small standing grain bits are many or the standing grain bits are bonded at the threshing work that influences on the fore worker, kinetic energy loss is big and short of money finishing can not be sent from threshing case or the mouth of doing short of money entirely.The threshing case that has is equipped with baffle plate at the threshing case back side, baffle plate is provided with arc spring lamination and is sent from short of money doing, but dried being kept in motion short of money is easy to be cut off by arc spring lamination, produces more short and small standing grain bits and leaks to advance to hold a vessel from end sieve, thereby increased peasant's the amount of labour and energy consumption.This has just increased use cost.
In sum, the deficiency that exists of the rice-wheat threshing case of prior art is: big, the short and small standing grain bits of kinetic energy loss are many further to have increased peasant's the amount of labour, short of money doing can not be sent from threshing case or the kinetic energy that mouthful reduced threshing operating efficiency and loss done short of money fully.
Summary of the invention
The purpose of this utility model is in order to overcome the prior art above shortcomings, a kind of eccentric type rice-wheat threshing case is provided, comprise casing, be arranged in the casing by the shaft-driven band tooth of transmission threshing cylinder, and the fore worker and the end sieve that are separately positioned on band tooth threshing cylinder dead ahead and below, the top board that grain-blocking plate that casing is provided with later and top are provided with, described power transmission shaft is connected with the pulley key that is arranged on the outer end of casing, it is characterized in that: the one or both ends of power transmission shaft are set to eccentric shaft, eccentric shaft is connected with an end of fore worker connecting rod, the other end of sieve connecting rod is connected with fore worker, drives fore worker and moves back and forth.
The advantage that the utility model has owing to said structure is conspicuous: the fore worker connecting rod can drive fore worker and do and move up and down, and makes short and small standing grain bits no longer influence threshing cylinder and rotates, and has saved kinetic energy; The axle of fore worker connecting rod is concentric with the power transmission shaft that drives threshing cylinder, has reduced the kinetic energy kinetic energy loss; Peasant's the amount of labour and use cost have been reduced.
Description of drawings
The utility model said structure can further specify by the non-limiting embodiment that accompanying drawing provides.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is Fig. 1 vertical view;
Fig. 3 is the structural representation of the utility model power transmission shaft;
Fig. 4 is the structural representation of the utility model screen cloth.
In the accompanying drawing: 1, casing; 2, band tooth threshing cylinder; 3, power transmission shaft; 4, eccentric shaft; 5, belt pulley; 6, fore worker; 7, end sieve; 8, enclose seat inserted link installing hole; 9, fore worker connecting rod; 10, back sieve; 11, top board; 12, screw thread; 13, connect support.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1, a kind of eccentric type rice-wheat threshing case among the figure, comprise casing 1, be arranged on the band tooth threshing cylinder 2 that drives by power transmission shaft 3 in the casing, and the fore worker 6 and the end sieve 7 that are separately positioned on band tooth threshing cylinder 2 dead aheads and below, the top board 11 that grain-blocking plate that casing 1 is provided with later and top are provided with, described power transmission shaft is connected with belt pulley 5 keys that are arranged on casing 1 an outer end, wherein: the one or both ends of power transmission shaft 3 are set to eccentric shaft 4, eccentric shaft 4 is connected with an end of fore worker connecting rod 9, the other end of sieve connecting rod 9 is connected with fore worker 6, drives fore worker 6 and moves back and forth.Short and small standing grain bits on the fore worker 6 no longer influence the threshing cylinder rotation like this, have saved kinetic energy.
In the said structure: fore worker connecting rod 9 is the Qu Duan that is bent by casing one side direction fore worker 6 directions with the link of fore worker 6; The two ends of fore worker connecting rod 9 are connected on eccentric shaft 4 and the fore worker 6, and the stage casing is bent by casing one side direction fore worker 6 directions respectively; One side of the base of described fore worker 6 and end sieve 7 flexibly connects and welds with fore worker connecting rod 9; Other one side of sieve of the described end 7 is affixed with the base of back sieve 10, and the height of back sieve 10 is concordant with the top board 11 on casing 1 top.This just makes short of money finishing be sent from threshing case or the mouth of doing short of money entirely, has reduced threshing operating efficiency and power consumption.
The axle head of described eccentric shaft 4 is provided with screw thread 12, is convenient to install fore worker connecting rod 9.
In the said structure: described casing 1 is fixedly connected on and connects on the support 13; The support 13 that is connected of the front top rake place of described casing 1 and casing 1 back is provided with and encloses seat inserted link installing hole 8, installs to enclose to prevent that grain or wheat are scattered on the ground because of the rotation of threshing cylinder produces centrifugal motion behind the seat, causes waste.
Said structure is work like this---by belt pulley 5 the power input being driven power transmission shaft 3 to rotate, band tooth threshing cylinder 2 and eccentric shaft 4 rotate and rotate along with power transmission shaft 3; Band tooth threshing cylinder 2 is with paddy or the wheat threshing sent into, and grain or wheat are just leaked by end sieve 7 and advance to hold the grain vessel, and short of money doing by back sieve 10 is sent from threshing case or the mouth of doing short of money fully; The rotation of eccentric shaft 4 simultaneously drives fore worker connecting rod 9 and moves, and moves up and down top short and small standing grain bits shake is fallen thereby drive fore worker 6.
In sum, the utility model in use can be sent from threshing case or the mouth of doing short of money entirely with short of money finishing, and has reduced the standing grain bits in grain or the wheat, has reduced the amount of labour, has saved the energy, has reduced use cost.
