Abstract
A screen mesh shaking device for a thresher is provided, which comprises a power device, a frame, a feeding port, a beater, a discharging port, a seed collecting channel, an air blast, a screen mesh and a screen mesh shaker. Wherein, the screen mesh comprises a fixed screen mesh fixed below the beater and a discharging screen mesh located at the discharging port. The utility model is characterized in that the screen mesh shaker comprises two rolling bearings and two link rods that are mounted at two ends of a rotary shaft of the beater, one ends of the two link rods are connected fixedly with bushes of the two rolling bearings, another ends of the two link rods are connected fixedly with the discharging screen mesh. In the utility model, the rotation of the rotary shaft of the beater acts on the rolling bearings, so that the balls in the rolling bearings will apply certain force onto the bushes so that the bushes will shake, which will drive through the two link rods the discharging screen mesh to shake, so as to screen efficiently and cleanly the seeds on the discharging screen mesh. The utility model is of simple structure, easy to mount and of low production cost, provides a new product for the industry of agricultural machinery.

Technical field
The utility model relates to field of agricultural machinery, specifically is a kind of thresher screen cloth shaking device.
Background technology
Common small-sized thresher generally all is provided with the screen cloth shaking device and is used for separating seed and slag charge, and its structure has various ways.A kind of thresher is arranged in the prior art; as the disclosed a kind of power thresher of China Patent No. ZL00264331.6; the structure of this thresher is " by power set; main frame; threshing cylinder; winnow drive; eccentric wheel; connecting rod; swing arm; arm; the screen cloth material guiding plate; winnow is formed; power set are installed in the main frame lower end; and be connected with threshing cylinder by driving belt; one end of threshing cylinder connects an eccentric wheel; eccentric wheel is connected with connecting rod; the other end of connecting rod connects swing arm; screen cloth material guiding plate one end connects swing arm; the other end connects arm, and the bottom of screen cloth material guiding plate connects winnow." though the thresher of this structure changes fixed screen cloth into swing type screen cloth material guiding plate, it is cleaner that grain sieve is got, however this swing type screen cloth shaking device structure more complicated, installation procedure are more loaded down with trivial details, production cost is than higher.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, provide a kind of simple in structure, install easily and the low thresher of production cost screen cloth shaking device.
The technical solution of the utility model is achieved in that
A kind of thresher screen cloth shaking device; comprise power set, frame, charging aperture, threshing cylinder, discharging opening, grain-collecting groove, air-blast device, screen cloth and screen cloth shaking device; wherein; described screen cloth comprises fixed grit that is installed in the threshing cylinder below and the discharging screen cloth that is arranged on the discharging opening position; its characteristics are: described screen cloth shaking device comprises two rolling bearings and two connecting rods that are installed in threshing cylinder rotating shaft two ends; one end of described two connecting rods is affixed with the bearing shell of two rolling bearings respectively, and the other end of two connecting rods is affixed with the discharging screen cloth respectively.
One end of wherein above-mentioned two connecting rods is welded in the bearing shell top of two rolling bearings respectively admittedly, and the other end of two connecting rods is welded in respectively on two side frames of discharging screen cloth admittedly.
The utility model screen cloth shaking device is owing to adopted two rolling bearings and two connecting rods that are installed in threshing cylinder rotating shaft two ends, one end of two connecting rods is affixed with the bearing shell of two rolling bearings respectively, the version that the other end is affixed with the discharging screen cloth respectively, rotary action by the threshing cylinder rotating shaft is in rolling bearing, make the ball of rolling bearing put on certain active force and make its vibrations to bearing shell, drive the vibrations of discharging screen cloth through the transmission of two connecting rods, thereby sieve the seed that drops out the online face of material screen effectively neatly.The utility model is simple in structure, and installation is easy and production cost is low, for the farm machinery industry provides a kind of novel product.
Below in conjunction with accompanying drawing the utility model is further described.
