The sequence of the mechanical action of whole device:

1: the work of motor 30 drives drive shaft 31 to rotate, so that first bevel gear 59 is driven to rotate, the idle running of the first belt pulley 33, To make second bevel gear 60 rotate, so that transmission shaft 61 and the first sprocket wheel 62 be made to rotate, make second by the transmission of chain 36 Sprocket wheel 35 rotates, to make the axis of rolling 38 and idler wheel 34 rotate, to make fixed block 37 move, to drive movable block 43, branch Fagging 11, fixed plate 13 and pushing plate 55 move downward, so that device be made to move in field water channel 10；

2: in device moving process, if there is tamper in water channel 12 and when saving bit by bit excessive in support plate 11, tamper with Being moved to the left for movable block 43 drives expansion plate 20 to move right, so that drive rod 22 be driven to move right with trapezoid block 28, presses Contracting spring 21 is compressed, and trapezoid block 28 leaves 27 upside of circular cone, and lifting spring 18, which resets, drives lifter plate 19 to rise, to make Circular cone 27 rises, so that it is tensioned belt 26, while lifter plate 19 rises drive link block 72 and limited block 73 rises, thus Increase first bevel gear 59, to make first bevel gear 59 separate with second bevel gear 60, to keep the first belt pulley 33 logical It crosses belt 26 and drives the rotation of the second belt pulley 23, to drive lifting shaft 24 to rotate, since limit plate 40 limits 49 turns of position-limited wheel It is dynamic, thus make lifting shaft 24 that rotating block 47 be driven to move upwards with position-limited wheel 49, so that support plate 11 is driven to move upwards, thus Move upwards tamper；

3: when support plate 11 moves upwards, after magnet block 65 is contacted with elevator 15, support plate 11, which rises, to be driven on elevator 15 It rises, to make elastic string 16 fluff, to make limit plate 40 reset under the action of adjustable spring 39, to make limit plate 40 not It is rotated in limitation position-limited wheel 49, support plate 11 stops rising at this time, and support plate 11 is located at 13 upside of fixed plate；

4: drive shaft 24 drives rotating block 47 to rotate, to drive position-limited wheel 49 and rotate gear 48 to rotate, to drive rotation Gear 53 rotates, to drive rotary shaft 51 to rotate, to drive bull wheel 52 to rotate, so that chain 14 is pulled, to make to slide Motion block 57 moves backward, to drive pushing plate 55 to move backward, so that tamper is released field water channel 10, sliding spring 58 It is stretched；

5: after releasing tamper, motor 30 drives drive shaft 31 to rotate backward, so that the power for exporting driving mechanism 69 is anti- To, lifting shaft 24 is rotated backward by the transmission of transmission mechanism 68, thus rotate backward rotating block 47 with rotating wheel 48, from And rotate backward rotation gear 53, rotary shaft 51 with bull wheel 52, to make chain 14 loosen, to make sliding shoe 57 in cunning It moves and resets under the action of spring 58, it is flexible so that pushing plate 55 be made to reset, and since 20 lower end of expansion plate offsets with support plate 11 Frictional force between plate 20 and support plate 11 cannot be such that compressed spring 21 resets, and the work of electromagnet 67 makes electromagnet 67 and magnet block 65 is attracting, to make elevator 15 move downward under the drive of two lifting springs 17, to drive limit by elastic string 16 Position plate 40 moves downward, and after limit plate 40 is again introduced into limiting groove 45, rotating block 47 declines with the rotation of lifting shaft 24, Until support plate 11 resets, support plate 11 is separated with expansion plate 20 at this time, and compressed spring 21 drives expansion plate 20 to reset, to make Drive rod 22 and trapezoid block 28 reset, so that circular cone 27 is resetted, lifter plate 19, link block 72, limited block 73 and the first cone Gear 59 declines, to make first bevel gear 59 engage with second bevel gear 60, so that motor 30 drives drive shaft 31 is positive to turn Dynamic, to make idler wheel 34 rotate by transmission, driving device continues to move downward, and clears up river.

The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with this field technology Personage can understand the content of present invention and be implemented, and it is not intended to limit the scope of the present invention.It is all according to the present invention Equivalent change or modification made by Spirit Essence, should be covered by the scope of protection of the present invention.
