The specific working principle of the operating mechanism is detailed below:
when the valve core of the multi-way valve crushing linkage 24 needs to be controlled to be opened towards the left side, the left foot is used for trampling the left side of the pedal of the left pedal assembly 2 downwards to drive the first ball head connecting rod 4 to move upwards, the third transmission sleeve 14 rotates clockwise around the lower transmission shaft 16 under the action of the upward pulling force of the first ball head connecting rod 4 to drive the corresponding connecting rod 19 to move leftwards, so that the valve core of the multi-way valve crushing linkage 24 is driven to move leftwards to realize opening, and after the trampling force of the left foot disappears, the valve core of the multi-way valve crushing linkage 24 automatically returns to the middle position to stop working under the action of the reset. When the valve core of the multi-way valve breaking linkage 24 needs to be controlled to be opened towards the right side, the movement process is opposite to the above, namely, the left foot is used for stepping down the right side of the pedal of the left pedal assembly 2, and the ball head connecting rod I4 is pushed to move downwards. The structure of the reset valve core of the reset spring is of the conventional design and is not shown in the attached drawings.
When the valve core of the multi-way valve deflection link 25 needs to be controlled to be opened towards the left side, the left side of the right pedal assembly 11 is stepped down by a right foot to drive the ball head connecting rod two 12 to move downwards, because the second transmission sleeve 9, the first transmission sleeve 7 and the upper transmission shaft 8 are connected into a whole through the first pin 10, therefore, the transmission sleeve I7 rotates anticlockwise around the upper transmission shaft 8 under the action of downward force and drives the ball head connecting rod III 13 to move downwards, because the six transmission sleeves 27 and the four transmission sleeves 17 are connected with the lower transmission shaft 16 into a whole through the second pin 26, therefore, the driving sleeve IV 17 rotates clockwise by taking the lower driving shaft 16 as the center under the action of downward force to drive the corresponding connecting rod 19 to move leftwards, thereby driving the valve core of the multi-way valve deflection link 25 to move leftwards to realize opening, when the treading force of the right foot disappears, and the valve core of the multi-way valve deflection link 25 automatically returns to the middle position to stop working under the action of a return spring. When the valve core of the multi-way valve deflection link 25 needs to be controlled to be opened towards the right side, the movement process is opposite to the above, namely, the right foot treads the right side of the right pedal assembly 11 downwards, and the ball head connecting rod two 12 is driven to move upwards. The structure of the reset valve core of the reset spring is of the conventional design and is not shown in the attached drawings.
When the valve core of the multi-way valve bulldozing unit 23 needs to be controlled to be opened towards the left side, the bulldozing control handle 15 is pushed forwards by a hand, the transmission sleeve five 20 is pulled by the push-pull flexible shaft 18 to rotate clockwise relative to the lower transmission shaft 16, the corresponding connecting rod is driven to move leftwards, so that the valve core of the multi-way valve bulldozing unit 23 is driven to move leftwards to realize opening, and when the pushing force of the hand disappears, the valve core of the multi-way valve bulldozing unit 23 automatically returns to the middle position to stop working under the action. When the valve core of the multi-way valve bulldozing unit 23 needs to be controlled to be opened towards the right side, the movement process is opposite to the movement process, namely, the bulldozing control handle 15 is pulled backwards by hands, and the transmission sleeve five 20 is pulled to rotate anticlockwise relative to the lower transmission shaft 16 through the push-pull flexible shaft 18. The structure of the reset valve core of the reset spring is of the conventional design and is not shown in the attached drawings.
Preferably, for avoiding external force mistake to step on left pedal assembly 2 and right pedal assembly 11, footboard apron 3 is all installed in left pedal assembly and right pedal assembly department, during the use, open the footboard apron can.
Preferably, the limiting bolts 1 are arranged between the bottom of the left pedal assembly 2 and the pedal bracket 28 and between the bottom of the right pedal assembly 11 and the pedal bracket 28, and the downward strokes of the left pedal assembly and the right pedal assembly can be limited by the corresponding limiting bolts respectively.
In conclusion, by adopting the control mechanism of the hydraulic multi-way valve, in the specific use process, the valve cores of the multi-way valve breaking connection and the multi-way valve deflection connection can be respectively opened leftwards and rightwards by operating the left pedal assembly and the right pedal assembly, the valve cores of the multi-way valve bulldozing connection can be opened leftwards and rightwards by operating the bulldozing control handle, and the opened valve cores can be automatically reset under the reset spring, so that the whole mechanism has the advantages of comfortable operation, stable performance, compact structure, convenience in manufacture and low cost, and is closer to the bearing force purchased by a user
