The contact surface of the coiled material 8 and the material is a smooth and anti-sticking material, and the other surface is a non-smooth surface. The coiled material 8 has good bending degree, is convenient to roll in, and has tensile resistance and high strength. The sleeve 10 is the same length as the cargo box. The interior space of sleeve 10 can accommodate the full length of web 8. The sleeve 10 has a slit through which the web 8 can enter the container. The width of the coil 8 is the same as the width of the membrane 7 on the container. The sleeve 10 is mounted higher on the container than the reel 6, the slit of the partition 7 is located in the upper middle of the container and the slit of the sleeve 10 is located at the top, so that space is reserved for gathering material for pulling out the coil 8. The length of the reel 6, coil spring 9 and sleeve 10 is the same as the longitudinal length of the cargo box.

Further, the reel 6 and the coil spring 9 are detachably attached to the web 8 by adhesion, thereby facilitating detachment of the web 8 for cleaning.

The embodiment provides a specific structure of a driving device: the driving device comprises a stepping motor 1, a first belt pulley 2 fixed on an output shaft of the stepping motor 1, a second belt pulley 5 fixed on a winding drum 6 and a belt 3 connected with the first belt pulley 2 and the second belt pulley 5, the sizes of the two belt pulleys can be changed according to the size of transmitted power, and the length of the belt 3 can also be flexibly set according to the position of the stepping motor 1. When the stepping motor 1 works, the stepping motor rotates forwards or backwards to drive the first belt pulley 2 to rotate, and the belt 3 drives the second belt pulley 5 to rotate so as to drive the winding drum 6 to rotate, thereby finally achieving the purpose of winding the coiled material 8.

Further, this excavator side direction cleaning device that emptys still includes the controller with step motor 1 electricity is connected, and this controller control step motor 1 is in order to separate the material and the return. Through setting up the controller to realize the return of automatic control separation material and coiled material 8.

In particular, both ends of the reel 6 are mounted on the cargo box by means of bearings 4. The winding drum 6 is fixed on the inner ring of the bearing 4, the bearing 4 is arranged on the inner wall hole of the cargo box, and the outer ring of the bearing 4 is in interference fit with the hole.

A central shaft is fixed in the sleeve 10, the coil spring 9 is sleeved on the central shaft, and when no material exists on the coiled material 8, the coiled material 8 enters the sleeve 10 under the action of the elastic force of the coil spring 9.

The sleeve 10 is mounted over the dump side interior wall of the cargo box (in a manner including but not limited to welding) with a gap between the exterior wall of the sleeve 10 and the interior wall of the cargo box for the drainage of water and small amounts of material.

In addition, a box body (the installation mode includes but is not limited to welding) is fixed on the outer side wall of the container, and the driving device is fixed in the box body. The stepping motor 1 is fixed on the box body, and the installation mode includes but is not limited to bolt connection. One end of the winding drum 6 penetrates through the container and extends into the box body, and the other end of the winding drum 6 is inserted into the bearing 4 on the inner wall of the other side of the container to be axially fixed.

The specific working process of the lateral dumping cleaning device of the excavator is as follows.

As shown in fig. 4, in the working state 1, when the container is filled with materials, the coil 8 does not exist on the winding drum 6, the coil 8 extends out of the sleeve 10 and gradually fits the three inner walls of the container, and as the amount of the materials is increased, the gap between the coil 8 and the inner wall of the container is eliminated, at this time, the coil 8 does not extend out any more, and the residual coil 8 in the sleeve 10 is slightly more than the external coil 8.

As shown in fig. 5, the work state 2 is the case where the dumping of the container is completed. During pouring, a portion of the web 8 has entered the sleeve 10 under the spring force of the coil spring 9, and the material on the web 8 is separated by the gap of the sleeve 10. After the turnover angle of the container reaches the maximum, the stepping motor 1 starts to rotate, the coiled material 8 enters the winding drum 6 through the gap of the partition board 7, the material is directly dropped out of the container after being separated by the partition board 7 until the coiled material 8 in the sleeve 10 is completely pulled out, the adhered material is completely separated, and the stepping motor 1 stops rotating.

As shown in fig. 6, in the working state 3, the container is returned, the stepping motor 1 is reversed, and the coil 8 is returned to the sleeve 10 by the elastic force of the coil spring 9 until no coil 8 remains on the reel 6. The coil 8 is now straightened in the container and when the material again enters the container, it will collect on the coil 8 and due to gravity the coil 8 is pulled out of the sleeve 10 into the active condition 1.

The work of step motor 1 is regulated and control by staff operation control ware, and step motor 1 starts when needs are assisted to be emptyd, adjusts step motor 1's rotation according to the adhesion condition of material to this reaches the purpose of empting completely. The device is circularly carried out according to the sequence of working states 1, 2 and 3, and the container is circularly carried out once when the container is toppled once.

1. The stepping motor 1 is used as a power device, and the rotation thereof is controlled by a controller. When the automatic rolling-up device works, whether the cleaning device is started or not can be determined according to the dumping condition of materials, or the rolling-up amount of the coiled materials 8 is required according to the condition, manual operation is not needed, and the time consumption of the whole process is short.

2. The lateral dumping cleaning device can increase the dumping angle again, the container does not need to be moved, when the winding drum 6 rotates, the coiled material 8 is stretched, the dumping angle is increased, residual materials can be removed along with the increase of the dumping angle again, and the residual adhesive materials are separated from the coiled material 8 through the gap of the partition board 7 and then are completely removed.

3. The stepping motor 1 is used as a power device, the winding drum 6 is used as a transmission part, and the power device is positioned outside the container, so that the space is saved, the number of transmission parts is small, the structure is simple, and the installation is convenient.

The invention further provides the excavator.
