Abstract
A rice and wheat threshing box with an adjustable screen comprises a toothed threshing cylinder connected into a box body through a transmission shaft, a belt pulley for power input at one outer end of the box body, the screen disposed in the front and under the toothed threshing cylinder, a grain stopper board disposed in the rear of the box body and a top board disposed on the top of the box body, wherein the screen is connected into the box body through stopper boards disposed at two ends of the toothed threshing cylinder, and the stopper boards are connected with the box body through bolts. By aid of the structure, the rice and wheat threshing box has the advantage of capabilities of increasing threshing efficiency and reducing use cost.
Description
Technical field
The utility model relates to the rice-wheat threshing case, the adjustable rice-wheat threshing case of particularly a kind of screen cloth.
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 screen cloth that is arranged on band tooth threshing cylinder dead ahead and below is formed.Use the thresher of prior art threshing case need so improve peasant's threshing operating efficiency; but still have a lot of problems: the standing grain bits push screen cloth by the band tooth threshing cylinder that rotates; make screen cloth be easy to distortion; thereby increased the distance between the separating tooth and screen cloth on the threshing cylinder; reduce threshing efficiency, thereby increased peasant's the amount of labour and energy consumption.This has just increased use cost.
In sum, the deficiency that the rice-wheat threshing case of prior art exists is: the screen cloth easy deformation, the amount of labour and the kinetic energy loss that have further increased the peasant cause use cost to improve greatly.
Summary of the invention
The purpose of this utility model is in order to overcome the prior art above shortcomings, a kind of adjustable rice-wheat threshing case of screen cloth that can improve threshing efficiency and reduce use cost to be provided.
The utility model is achieved through the following technical solutions, the adjustable rice-wheat threshing case of a kind of screen cloth, comprise the belt pulley that is connected band tooth threshing cylinder in the casing and the outer end of casing by power transmission shaft for the power input, and be arranged on the top board that the screen cloth of band tooth threshing cylinder dead ahead and below, grain-blocking plate that casing is provided with later and top are provided with, wherein: described screen cloth is connected in the casing by the baffle plate that is arranged on band tooth threshing cylinder two ends, and baffle plate is connected with casing by bolt.
The advantage that the utility model has owing to said structure is conspicuous: by regulating bolt, make screen cloth be in best threshing position forever in threshing course, can not cause the low and power consumption of threshing efficiency because of its distortion; So this structure has improved threshing efficiency and has reduced use cost.
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.
In the accompanying drawing: 1, casing; 2, band tooth threshing cylinder; 3, power transmission shaft; 4, screen cloth; 5, belt pulley; 6, top board; 7, baffle plate; 8, bolt.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1, the adjustable rice-wheat threshing case of screen cloth among the figure, comprise the belt pulley 5 that is connected a band tooth threshing cylinder 2 in the casing 1 and casing 1 an outer end by power transmission shaft 3 for the power input, and be arranged on the top board 6 that the screen cloth 4 of band tooth threshing cylinder 2 dead aheads and below, grain-blocking plate that casing 1 is provided with later and top are provided with, it is characterized in that: described screen cloth 4 is connected in the casing 1 by the baffle plate 7 that is arranged on band tooth threshing cylinder 2 two ends, and baffle plate 7 is connected with casing 1 by bolt 8.
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 rotates and rotates along with power transmission shaft 3; The band 2 pairs of spikes of rice of sending into of tooth threshing cylinder or the wheat head carry out threshing, and grain or wheat are just leaked by screen cloth 4 and advance to hold the grain vessel.In threshing course, separating tooth on the band tooth threshing cylinder 2 is squeezed in paddy or wheat at a high speed on the screen cloth 4, this just makes screen cloth 4 in use be out of shape, at this moment, only need to regulate bolt 8, along with to the compressing downwards of baffle plate 7, screen cloth 4 is moved up, thereby guarantee that screen cloth 4 and separating tooth on the band tooth threshing cylinder 2 are in this position of best threshing.
In sum, the utility model has in use improved threshing efficiency and has reduced use cost.
