Description
Technical field
The utility model belongs to the drive system in hay mower field, particularly a kind of improved self-propelled mower.
Background technology
Along with sending out of urban afforestation, the lawn occupation rate improves year by year, and court, lawn, greenery patches, garden occur in a large number simultaneously.For maintenances such as the pruning on lawn, maintenances, generally all adopt hay mower now, the self-propelled power mower of China's production at present generally all is to drive power wheel by engine by gearbox, clutch, finish walking function, but this kind type of drive transmission efficiency is low, be difficult to finish the map function that turns to, advances, falls back simultaneously, operate loaded down with trivial details, the fault rate height.
Summary of the invention
The purpose of this utility model is a kind of improved hay mower drive unit, finishes driving by hydraulic transformer.
The utility model is achieved in that
The hay mower drive unit, mainly comprise the engine and the driving wheel that are installed on the body, it is characterized in that: also be provided with hydraulic transformer on the body, the belt pulley of hydraulic transformer is driven by above-mentioned engine by transmission, and the output shaft of hydraulic transformer links to each other with driving wheel; The flow control board of hydraulic transformer connects joystick.
After the utility model adopts said structure, owing to adopt two hydraulic transformers to drive two driving wheels respectively, infinitely variable speeds, transmission smoothness, transmission efficiency height, power are exported powerful; By difference control to hydraulic transformer, realized mower advancing nimbly and freely smoothly, fallen back, function such as turning, and can change arbitrarily, control flexibly, convenient, can finish the mower no-radius and turn, have novel structure, effect flexible to operation.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the end view of Fig. 1, and Fig. 3 is drive principle figure of the present utility model.
In the accompanying drawing, 1 be body, 2 for engine, 3 for driving wheel, 4 for hydraulic transformer, 5 for driving belt, 6 for flow control board, 7 for expansion tightening wheel, 8 for pinch roller, 9 for joystick, 10 for the tensioner extension spring, 11 for the control pull bar, 12 for walking control lever, 13 for the speed changer control lever.14 is that return spring, 15 is the braking locking plate.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in Figure 1, 2, the utility model is the novel type of drive of hay mower, mainly form by body 1, body 1 be provided with engine 2, cutter, two joysticks 9, two hydraulic transformers 4 and about two driving wheels 3.The output wheel of engine 2 drives hydraulic transformer 4 work by the belt pulley of driving belt 5 connection left and right sides hydraulic transformers 4, and hydraulic transformer 4 is made up of motor and oil pump.The output shaft of hydraulic transformer 4 links to each other with left and right sidesing driving wheel 3 respectively.Two joysticks 9 are separately positioned on the left and right sides control arm of body 1, and joystick 9 connects control pull bar 11 respectively, and the upper end bending part of control pull bar 11 links to each other with joystick 9, and are positioned at braking locking plate 15 grooves; The other end of speed change pull bar 11 links to each other with walking control lever 12, and walking control lever 12 is arranged on the body 1, can rotate around axis under the pulling of speed change pull bar 11; About walking control lever 12 connect left and right sides speed changer control lever 13 respectively, left and right sides speed changer control lever 13 directly and the flow control boards 6 on the left and right sides hydraulic transformer 4 link to each other, reach the purpose of effective control hydraulic transformer 4 rotating speeds by flow control board 6.Also be respectively equipped with return spring 14 on the walking control lever 12.The braking locking plate 15 on the design neutral position, progressive position are arranged, the position of falling back.
As shown in Figure 3, for guaranteeing the transmission effect, also be provided with expansion tightening wheel 7 and pinch roller 8 on the above-mentioned driving belt 5; Expansion tightening wheel 7 is connected with tensioner extension spring 10.By the tension force of tensioner extension spring 10 adjustment expansion tightening wheels 7, guarantee the enough power of hydraulic transformer 4 outputs.
During use, ato unit 2, the output wheel high speed rotating of engine 2, by driving belt 5 under the effect of pinch roller 8 and expansion tightening wheel 7, the belt pulley that drives hydraulic transformer 4 rotates simultaneously, the output shaft rotation of hydraulic transformer 4 also produces enough torques, directly drives the driving wheel 3 that is attached thereto and rotates, and drives the mower walking.
During operation, joystick 9 is at neutral position, and flow control board 6 is at horizontal level, and hydraulic transformer 4 is output speed not.Rolling brake locking plate 15, release on control handle 9, under the effect of return spring 14, about the walking control lever 12 rotate around axis, clockwise rotate by speed changer control lever 13 pulling flow control boards 6, hydraulic transformer 4 flows increase, output speed and torque, and mower moves ahead under the drive of driving wheel 3.Joystick 9 displacements are big more, and the angle of flow control board 6 rotations is just big more, and hydraulic transformer 4 output speeds are high more.
Otherwise during pinching joystick 9, flow control board 6 rotates counterclockwise backward, and hydraulic transformer 4 output speeds reduce, when flow control board 6 surpasses horizontal level (neutral position), the commutation of hydraulic transformer 4 internal hydraulic pressures oil, hydraulic transformer 4 reversings, mower falls back.
Because two hydraulic transformers 4 drove about mower adopted, and each hydraulic transformer 4 is controlled by joystick 9 by separately flow control board 6, speed changer control lever 13, walking control lever 12, control pull bar 11 respectively, can control the speed of two driving wheels 3 respectively, form different rotating speeds, thereby reach the purpose of turning.Also can realize the turning of mower no-radius by 3 reversings of a driving wheel, another mode of just changeing.
