Abstract
The utility model discloses a power transmission device of a rootstock excavator. According to the power transmission device, a speed reducing box is connected between two front ends of two edge beams, a circulation chain box transmission shaft is arranged between back ends of the two edge beams through a bolt and a baring seat, a pair of bridge type fan-shaped gears is arranged in the speed reducing box, a power input shaft extending from the front of the speed reducing box is arranged on the bridge type fan-shaped gear in front of the speed reducing box, output shafts at two ends of the bridge type fan-shaped gear at the back of the speed reducing box are respectively connected with a half-floating semi-shaft, outer ends of the two half-floating semi-shafts respectively extend outside the edge beams through the bearing seat from the inside of the speed reducing box, and are respectively provided with a chain wheel, two ends of the circulation chain box transmission shaft are respectively provided with a back chain wheel, the back chain wheels are respectively provided with a power output shaft crank shaft connecting rod, and a chain is connected between a front chain wheel and a back chain wheel which are arranged on one side. The power transmission device has the advantages of being simple in structure, light in weight, small in size, low in energy consumption, high in efficiency, low in noise, and stable and reliable in work.
Description
Technical field:
The utility model relates to farm machinery, and particularly a kind of being applicable to is installed on the rhizome excavator simple in structurely, and intensity is big, working stability, the rhizome excavator actuating unit that energy consumption is low, efficient is high.
Background technique:
Present rhizome excavator actuating unit is to slow down at gearbox to drive to the work major axis by belt pulley with many strap speed varyings.Such structure is following shortcoming because unreasonable structure exists: 1, gearbox Heavy Weight volume is big; 2, big, the poor stability of energy consumption; 3, off-axis, the easy displacement of spindle bearing holder easily take place in two overhung crank major axis; 4, because crossbeam needs the many places welding, produce loaded down with trivial details easy-rupturing, the maintenance cost height.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, and intensity is big, working stability, the rhizome excavator actuating unit that energy consumption is low, efficient is high.
The technical solution of the utility model is finished as follows, a kind of rhizome excavator actuating unit, it includes two side bars that fix with body, it is characterized in that: front end is connected with a speed reducer with bolt between two side bars, between two side bar rear ends, with bolt and bearing support a circulation chain box transmission shaft is installed, a pair of bridge-type tooth sector is installed in speed reducer, bridge-type tooth sector in front at speed reducer is equipped with a power input shaft that stretches out from speed reducer the place ahead, on the output shaft at the bridge-type tooth sector two ends of back, be connected with a semifloating axle shaft respectively, the outer end of two semifloating axle shafts respectively in the speed reducer outside bearing support reaches side bar, be separately installed with a sprocket wheel in the outer end of each semifloating axle shaft, sprocket wheel after circulation chain box transmission shaft two ends are separately installed with one, sprocket wheel is separately installed with power output crank axle connecting rod before and after each, is connected with chain between the sprocket wheel of the front and back of a side.
The utlity model has simple in structure, in light weight, volume is little, energy consumption is low, efficient is high, noise is little, the stable and reliable operation advantage.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, it includes two side bars 4 that fix with body, between two side bar front ends, be fixedly connected with a speed reducer 11 with bolt 10, between two side bar rear ends, with bolt and bearing support a circulation chain box transmission shaft 8 is installed, a pair of bridge-type tooth sector 2 is installed in speed reducer, bridge-type tooth sector in front at speed reducer is equipped with a power input shaft that forwards stretches out 1, on the output shaft 12 at the bridge-type tooth sector two ends of back, be connected with a semifloating axle shaft 3 respectively, the outer end of two semifloating axle shafts respectively in the speed reducer outside bearing support reaches side bar, be separately installed with a sprocket wheel 5 in the outer end of each semifloating axle shaft, sprocket wheel 7 after circulation chain box transmission shaft two ends are separately installed with one, sprocket wheel is separately installed with power output crank axle connecting rod 9 before and after each, is connected with chain 6 between the sprocket wheel of the front and back of a side.This device directly drives the integrated output that sprocket wheel and chain and each crankshaft thereof are finished required drive synchronously by the semifloating axle shaft at two ends, the left and right sides with the bridge-type tooth sector through speed reducer, the phenomenon of easy off-axis when having avoided a major axis job, stop to adopt in the root crop excavator gearbox to slow down simultaneously and driven the big defective of energy consumption that the small belt pulley raising speed causes by big belt pulley and Duo Gen belt, have that volume is little, in light weight, working stability is reliable, the advantage that energy consumption is low, noise is little, efficient is high.
