1601, to make brake(-holder) block 1601 resist fixed frame 1, so that fixing angular adjustment bar 16 can not rotate；By banking pin
1602 with removed at brake(-holder) block 1601, brake(-holder) block 1601 can not resist fixed frame 1, so as to make angular adjustment bar 16 around
The rotation of its shaft, lever rotate in arc groove 101, and then adjust angle to the electric telescopic pipe of connection fixed thereto 13.
The adjustment process of telescopic nutted rod 19 is, by twisting telescopic nutted rod 19, to make casing and threaded rod 1902
Cooperate, and then it is made to extend or shorten, adjusts length, and then the electric telescopic pipe 13 that is strained and fixed.
Bamboo basket is caught on by iron hook 20, the work rotation of driving motor 10 is controlled by control switch, drives the second belt pulley
11 rotations, are driven by belt 12, drive the rotation of the first belt pulley 8, and then rotate with action roller shaft 5, the scrolling rope made of hemp 7 makes iron hook
20 fall, so that bamboo basket be made to drop to the bottom Jing Jiao, are loaded crops；After loading, 10 turns of Reverse Turning Control driving motor
To, by the same course of work, the bamboo basket of crops will be loaded with, from the bottom Jing Jiao rise；The rope made of hemp 7 is wrapped around on roll shaft 5,
It is provided on roll shaft 5 only around piece 6, for limiting winding position of the rope made of hemp 7 on roll shaft 5；Pass through the control of control switch 21 first
Electric pushrod work in track groove 2, the second track groove, band movable slider move in corresponding track groove, drive bearing spider
3, driving motor 10 moves；Bearing spider 3 moves, and band dynamic bearing 4 moves, and band action roller shaft 5 moves, and then drives on iron hook 20
Bamboo basket carries out translational motion, facilitates and transports bamboo basket on wagon box, saves user's work；Reverse Turning Control after the completion of translation is received
Bamboo basket is returned to initial position, completes a workflow.
If, sometimes due to quality is overweight, excess load is caused to rotate in bamboo basket uphill process, under bamboo basket can be caused quick
Drop can control the braking of driving motor 10 by control switch 21 and stop, so that the bearing 4 of two sides and driving motor 10 is included
Axis is only stopped at once, so that roll shaft 5 stops, preventing bamboo basket from falling, driving motor 10 will stop working at this time, it is therefore prevented that short
Path loss is bad；Bearing 4 and miniature motor 10 from tape spool according to weight slow relaxation, cooperate manual control hand crank 17 so that
Roll shaft 5 slowly rotates, and bamboo basket is slowly sent to the bottom Jing Jiao, then decreasing amount adjustment, rises again.
It is worth noting that: whole device realizes control to it by main control button, sets since control button is matched
Standby is commonly used equipment, belongs to existing mature technology, details are not described herein its electrical connection and specific circuit structure.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
