Abstract
The invention relates to an improved tailing thresher which comprises a machine frame and a feeding tube which is fixedly installed on the machine frame. A screw shaft is installed in the feeding tube, above which a feed inlet port is provided, one end of the feeding tube is fixedly connected with a threshing grain discharging tube, a side scrubbing disc is fixedly installed on the inner side wall of the threshing grain discharging tube which is arranged at one side of the screw shaft, one end of the screw shaft on the threshing grain discharging tube is provided with a splined shaft which is coaxial with the screw shaft, a main scrubbing disc is installed on the splined shaft in a way of axial movement, the end of the splined shaft is fixedly installed with a baffle, a spring is sheathed and installed on the splined shaft between the main scrubbing disc and the baffle; the end of the screw shaft which is arranged on the other end of the feeding tube is connected with a drive motor through a transmission device. The tailing thresher can be used for threshing the tailing ears of wheat. The threshing grain discharging device of the thresher can be adjusted properly by arranging an adjusting device to facilitate grains which can enter the threshing grain discharging tube to thresh fully, thereby improving the threshing effect and avoiding loss of grains.
Description
Technical field
The present invention relates to a kind of farm machinery, specifically a kind of improved impurity thresher.
Background technology
At present, a large amount of uses along with combine, because the threshing effect of combine is bad, contain a large amount of assorted surplus in the grain of results, these assorted surplus middle overwhelming majority are operable wheat heads, and at grain processing plant and peasant household's family, these wheat heads be owing to can't process threshing, and can only handle as feed.If these assorted surplus processing and utilizations will can be saved a large amount of grain for country.
Summary of the invention
The purpose of this invention is to provide a kind of assorted surplus wheat head threshing, effective improved impurity thresher of threshing of being used for.
For achieving the above object, the present invention is by the following technical solutions:
Improved impurity thresher of the present invention comprises frame, be fixedly mounted on the feed cylinder on the frame, screw-conveyer-shaft is installed in the feed cylinder, the top of feed cylinder has charging aperture, it is characterized in that: the end at feed cylinder is fixedly connected with the threshing discharge barrel, the threshing discharge barrel is positioned on the madial wall of screw-conveyer-shaft one side and is installed with secondary scratching plate, an end that is positioned at the threshing discharge barrel on the screw-conveyer-shaft has the splined shaft coaxial with it, on this splined shaft can main scratching plate being installed axially movable mode, spline the tip of the axis fixed installation baffle plate is set with spring on the splined shaft between main scratching plate and the baffle plate; Other end auger the tip of the axis at feed cylinder is in transmission connection by transmission device and drive motors.
The threshing discharge barrel is the round drum type housing that has end cap, and its side has discharging opening, and splined shaft is inserted on the end cap by bearing.
Owing to adopted technique scheme; improved impurity thresher can be used for assorted surplus wheat head threshing, by adjusting device is set the threshing drawing mechanism is carried out suitable adjusting, can make the sufficient threshing of the cereal that enters the threshing discharge barrel; improve the threshing effect, prevented the waste of cereal kernel.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the present invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Improved impurity thresher comprises frame 1, is fixedly mounted on the feed cylinder 2 on the frame 1, and screw-conveyer-shaft 4 is installed in the feed cylinder 2, and the top of feed cylinder 2 has charging aperture 21.End at feed cylinder 2 is fixedly connected with threshing discharge barrel 3, threshing discharge barrel 3 is positioned on the madial wall of screw-conveyer-shaft 4 one sides and is installed with secondary scratching plate 6, an end that is positioned at threshing discharge barrel 3 on the screw-conveyer-shaft 4 has the splined shaft coaxial with it, can main scratching plate 5 being installed axially movable mode, the spline the tip of the axis fixedly mounts baffle plate 8 on this splined shaft.Spline housing 7 is set on splined shaft, main scratching plate 5 is fixedly mounted on the spline housing 7, it is can be on splined shaft axially movable and can not rotate making main scratching plate 5, realize all are entered the assorted surplus threshing fully of carrying out of cereal in the threshing discharge barrel 3 by changing distance between main scratching plate 5 and the secondary scratching plate 6, by the rotation of main scratching plate 5 seed and assorted surplus discharging opening 31 below being positioned at threshing discharge barrel 3 are dished out at last, realize the purpose of threshing.On the splined shaft between main scratching plate 5 and the baffle plate 8, be set with spring 9; Threshing discharge barrel 3 is for having the round drum type housing of end cap 32, and its side has discharging opening 31, and splined shaft is inserted on the end cap 32 by bearing.End at the other end screw-conveyer-shaft 4 of feed cylinder 2 is connected with feed cylinder 2 by bearing, and the end of screw-conveyer-shaft 4 is installed with belt pulley, and is in transmission connection by this belt pulley and driving belt and drive motors 10.
In the course of the work, drive motors 10 work drive screw-conveyer-shaft 4 rotations, and drive main scratching plate 5 rotations by splined shaft, because the thrust of spring 9, main scratching plate 5 is positioned at the position of the most close secondary scratching plate 6, and the gap between promptly main scratching plate 5 and the secondary scratching plate 6 is very little.When starting, main scratching plate 5 produces friction with secondary scratching plate 6, should avoid main scratching plate 5 directly to contact with secondary scratching plate 6, makes it have a certain clearance when static.When the assorted surplus transmission by screw-conveyer-shaft 4 and auger 41 of cereal is transported in the threshing discharge barrel 3, overcome the thrust of thrust spring, main scratching plate 5 is backed down, in the assorted surplus process that enters threshing discharge barrel 3 of cereal, through the purpose of main scratching plate with the relative motion realization threshing of secondary scratching plate.
