Abstract
The invention discloses a granular material screening machine. The granular material screening machine comprises a machine frame. The front portion of the machine frame and the rear portion of the machine frame are connected with a driving shaft and a supporting shaft in a rotary mode respectively, a power device used for driving the driving shaft to rotate is installed on the machine frame, cranks are installed at the two ends of the driving shaft, a screening basket which is arranged downwards in an inclined mode from front to back is hinged to the supporting shaft, a connecting rod is hinged between the front end of the screening basket and the cranks, and a discharged material supporting plate is arranged at the rear end of the screening basket. The granular material screening machine is convenient to manufacture, install and operate and has the advantages of being high in screening efficiency and high in unloading efficiency.
Description
Technical field
The present invention relates to a kind of particulate material screening machine.
Background technology
At present, the structure of existing screening machine comprises frame, is elasticly connected with screening basket in frame, on screening basket, vibrating motor is housed, and the vibrations by vibrating motor make screening basket produce shake, thereby realize the screening of material.Because the vibration frequency of vibrating motor is too frequent, there is the shortcoming that screening efficiency is low while sieving for the larger material of grain graininess difference in the screening machine of this structure, and rerolling phenomenon easily appears in material again that sieve out.Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of screening efficiency is high, discharge rate is prone to the particulate material screening machine of rerolling soon and not.
For solving the problems of the technologies described above, the particulate material screening machine providing comprises frame, its design feature is: the front and rear of frame is rotatably connected to respectively driving shaft and back shaft, the power set that order about drive shaft turns are housed in frame, crank is equipped with at the both ends of driving shaft, on back shaft, be hinged with from the screening basket that goes to rear-inclined to arrange downwards, between the front end of screening basket and crank, be hinged with connecting rod, the rear end of screening basket is provided with discharging supporting plate, the stock guide of stretching under its horizontal side direction opposite side tilts is also equipped with in the bottom of frame, the material baffle between discharging supporting plate and stock guide rear portion is equipped with at the rear portion of frame.
Described power set comprise the engine being connected in frame, and the power output shaft of described driving shaft and engine is in transmission connection by sprocket wheel chain.
The bottom of described screening basket is connected with the hinged cover that is inverted U, and described hinged shroud is buckled on back shaft.
Described screening basket comprises the guide section at anterior screening section and rear portion, the front portion of screening section and both sides have and are the overhanging guide backplate of bottom-up inclination, the bottom of screening section is provided with screen cloth, the both sides of guide section have the stock guide of vertical setting, and guide backplate is connected by rebound with stock guide.
Adopt after said structure, by power set, order about drive shaft turns, by crank, connecting rod, drive the front portion of screening basket to teetertotter, when screening basket teetertotters, large granular materials after screening can be unloaded it by the uphill process by its rear portion fast, large granular materials flows out from discharging supporting plate, small particles material leaks down from screening basket bottom, the stock guide arranging can be by a horizontal side of the material guiding frame of sieving out, and arranging of material baffle can effectively prevent that the phenomenon of rerolling from appearring in the material sieving out.In sum, manufacture of the present invention, installation, easy to operate, have advantages of that screening efficiency is high, discharging efficiency is high and effectively prevent rerolling.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Fig. 1 is the structural representation of a kind of most preferred embodiment of the present invention;
Fig. 2 is the perspective view that in Fig. 1, embodiment removes power set.
The specific embodiment
Particulate material screening machine as depicted in figs. 1 and 2, it comprises frame 1, the front and rear of frame 1 is rotatably connected to respectively driving shaft 3 and back shaft 2, in frame 1, be equipped with and order about the power set that driving shaft 3 rotates, power set comprise the engine 8 being connected in frame 1, this engine 8 can be buncher, thereby can accurately control the rotating speed of driving shaft 3, described driving shaft 3 is in transmission connection by sprocket wheel chain with the power output shaft of engine 8, crank 4 is all equipped with at the both ends of driving shaft 3, on back shaft 2, be hinged with from the screening basket 5 that goes to rear-inclined to arrange downwards, the front end of screening basket 5 is provided with otic placode, between otic placode and crank 4, be hinged with connecting rod 6, 4 pairs of screening basket 5 front portions of two cranks are set and carry out 2 drivings, thereby make swinging up and down of screening basket 5 front portions more steady, the rear end of screening basket 5 is provided with discharging supporting plate 7, the stock guide 10 of stretching under its horizontal side direction opposite side tilts is also equipped with in the bottom of frame 1, the material baffle 11 between discharging supporting plate 7 and stock guide 10 rear portions is equipped with at the rear portion of frame 1.
As depicted in figs. 1 and 2, the bottom of screening basket 5 is connected with the hinged cover 9 that is inverted U, and the bottom of hinged cover 9 is uncovered, and described hinged cover 9 covers are buckled on back shaft 2, screening basket 5 can be unloaded from back shaft 2, and maintenance is easy for installation and maintenance.
The above is specific constructive form of the present invention, and the present invention is not restricted to the described embodiments, and the art personnel, the equivalent variations based on concrete structure in the present invention and parts are replaced all in protection scope of the present invention.
