Utility model content
The purpose of this utility model is to provide a kind of reaping machine cleaning plant, to solve the easily technical problem of fracture of cantilevered axle that eccentric chain-wheel of the prior art is that be provided with and power intake kinematic link is hinged.
For achieving the above object, reaping machine provided by the utility model by the technical scheme of cleaning plant is: reaping machine cleaning plant, comprise frame and be arranged on the driving mechanism for driving shuttle board and screen box to vibrate in frame, driving mechanism comprises kinematic link, kinematic link has power intake and the clutch end to shuttle board and screen box output vibratory drive power by transmission connecting structure, described driving mechanism also comprises by bearing arrangement and rotates the power input shaft being assemblied in frame, described bearing arrangement has at least two covers along power input shaft is axial arranged, on power input shaft, there is the crankshaft section between two cover bearing arrangements, the connecting rod neck of crankshaft section and the power intake of described kinematic link are articulated and connected.
Described kinematic link comprises having the input part of described power intake, the efferent with described clutch end and middle linkage section, and the two ends of middle linkage section are assembled with input part, the corresponding spiral of efferent respectively or fix assembling by bearing pin and input part, efferent respectively with contrary rotation direction.
On described power input shaft, be installed with belt pulley or sprocket wheel as power input wheel.
Described transmission connecting structure comprises with the parallel layout of described power input shaft and rotates the driving shaft being assemblied in frame, on driving shaft, be installed with transmission arm, the clutch end of kinematic link and described transmission arm are hinged, on driving shaft, coaxial spline is equipped with driving swing arm, drives swing arm hinged respectively with point shuttle board being arranged and screen box.
Usefulness of the present utility model is: the power input shaft that the driving mechanism in cleaning plant provided by the utility model adopts the rotation at two ends to be assemblied in frame drives kinematic link action, connecting rod neck on the crankshaft section of power input shaft and the power intake of kinematic link are hinged, like this, in the time that power input shaft rotates, can drive kinematic link to move reciprocatingly by crankshaft section, and then drive shuttle board and screen box to make double vibrations by kinematic link.Because the crankshaft section on power input shaft is between two cover bearing arrangements, form 2 supportings, and then guaranteed under the reciprocating prerequisite of kinematic link, can effectively bear larger driving load, be not easy to occur the situation of crankshaft breakdown, and then can effectively guarantee the normal work of cleaning plant.
Further, input part, efferent spiral assembling respectively by middle linkage section with contrary rotation direction and kinematic link, can pass through like this to rotate middle linkage section to adjust the length of kinematic link, and then the vibration of shuttle board and screen box is adjusted.
Further, on power input shaft, be installed with belt pulley or sprocket wheel as power input wheel, like this, like this for the reaping machine of installing and using this cleaning plant, can drive power input shaft to rotate by belt transmission or chain drive, and then drive kinematic link to move reciprocatingly.
Further, shuttle board and screen box are divided and be arranged, and drive respectively shuttle board and screen box to vibrate by the driving swing arm being in transmission connection by driving shaft, transmission arm and kinematic link, can effectively improve like this screening effeciency of cleaning plant.
