[0037] The transmission mechanism includes a support block 15 fixed on the bracket 1 and a transmission cylinder 6 obliquely arranged on the support block 15, a driving motor 60 is provided at the upper end of the transmission cylinder 6, and a strap 61 is provided at the lower end of the transmission cylinder 6; a driving tooth 62 and a first screw shaft 63 are concentrically provided at the output end of the driving motor 60, a driven tooth 64 meshingly connected to the driving tooth 62 is provided on one side of the transmission cylinder 6, a second screw shaft 65 is concentrically provided on the driven tooth 64, and the blades of the first screw shaft 63 and the second screw shaft 65 are staggered with each other; a discharge port 66 is connected to the lower end surface of the upper end of the transmission cylinder 6.

[0038] A strap 61 adjacent to the two rubber toothed discs is provided at the lower end of the conveying cylinder 6. One end of the strap 61 is threadedly connected to the conveying cylinder 6, and the other end is provided with a curved surface section abutting against the ground, and a tooth groove 611 is provided on the curved surface section along the circumferential direction.

[0039] The operating principle of the utility model is as follows:

[0040] like Figures 1 to 10As shown, first of all, in view of the fact that the utility model is used in the deep cabin of the ship, remote control is required, so a PLC controller (not shown) connected to the active motor 2, the driven motor 3, the linear motor 13 and the drive motor 60 is preset on the support frame 14, and then the operator uses a control console (not shown) wirelessly connected to the PLC controller outside the deep cabin to realize the opening and closing operations.

[0041] When in use, the control console first turns on the active motor 2 to drive the active wheel 21 to rotate synchronously with the track 10. Since a correction belt 11 is wound on the inner side wall of the track 10 along the axial direction of the track 10, and a synchronous tooth groove 12 is provided on the correction belt 11, the wheel surfaces of the active wheel 21, the supporting wheel 20 and the driven wheel 22 are all provided with tooth blocks 23 meshing with the synchronous tooth groove 12, which can prevent the wheels from slipping and deviating on the track 10 and ensure the transmission efficiency. At the same time, an anti-skid rack 121 is wound on the outer side wall of the track 10 along the axial direction of the track 10 to improve the grip of the track 10.

[0042] After the belt moves into place, the active motor 2 is turned off, and the driven motor 3 and the driving motor 60 are turned on at the same time. The driven motor 3 synchronously drives the rotating wheel 30, the driven wheel 31 and the two connecting rods 32 to rotate, that is, the two rubber toothed discs arranged in opposite spiral directions also rotate synchronously, while gathering the coal slag to the position between the two crawlers 10, the first rubber toothed disc 331 and the second rubber toothed disc 332 also drive the coal slag to move to the transmission cylinder 6 through the strap 61. The coal slag moved into the transmission cylinder 6 is then moved to the upper end of the transmission cylinder 6 by the first screw shaft 63 and the second screw shaft 65 at the same time, and is sent to the conveyor belt or other related storage devices at the discharge port 66 to achieve the purpose of cleaning the cargo hold.

[0043] During the above-mentioned use, it should be noted that a bearing is sleeved on the outer side of each rotating wheel 30, and a driven wheel 22 is sleeved on the outer side of each bearing, so that the rotation of the driven wheel 22 and the rotating wheel 30 does not affect each other, that is, when the bracket 1 is moving or stationary, the rotating wheel 30 can be started to drive the two rubber toothed discs for cleaning.

[0044] In order to reduce the stroke for cleaning the coal cinder, the distance between the follower wheel 31 and the strap 61 should be shortened. Specifically, the linear motor 13 is turned on the control console in a timely manner to drive the pin 131 inserted in the connecting sleeve 48 to move back in the direction of the linear motor 13, that is, the pin 131 drives the connecting sleeve 48 to rotate counterclockwise, and the coal cinder is shoveled and swept in combination with the rotation speed of the follower wheel 31 and the toothed structure of the rubber toothed disc 33, which is conducive to directional and rapid cleaning of the coal cinder; at the same time, a tooth groove 611 is provided on the curved surface section of the strap 61 in the circumferential direction, and the tooth groove 611 at the lower end is directly in contact with the ground to avoid forming a cleaning gap and causing cleaning omissions. The setting of the tooth groove 611 forms a space for friction deformation and giving way on the strap 61, which can reduce wear and extend the service life while meeting the requirement of being close to the ground; since the strap 61 is screwed to the conveying cylinder 6, it is also very convenient to disassemble and replace it after it is worn out.

[0045] Similarly, when the belt between the rotating wheel 30 and the driven wheel 31 becomes loose due to rotation loss, the elastic force of the compression spring 51 will pull the connecting plate 45 and the roller 46 to move toward the direction of the guide cylinder 5 at the same time, that is, to cling to the inner wall of the transmission belt again, so as to straighten the transmission belt and ensure the transmission efficiency.

[0046] In addition, since the blades of the first spiral shaft 63 and the second spiral shaft 65 are staggered with each other and rotate in opposite directions due to the gear transmission, during the process of conveying the coal slag, each adjacent section of the blades between the two rotating shafts can form a rotational extrusion on the coal slag, and this continues from the feeding position at the lower end of the conveying cylinder 6 to the position of the discharge port 66, which is beneficial to crushing the coal slag and facilitates subsequent transportation and processing.
