The material barrel 11 is used for bearing materials. The main body 1 is arranged in the middle of the bracket 2, and the connection mode can be bolt 8 connection. The stand 2 serves to provide support to the main body 1. The bottom of the main body 1 and the bracket 2 is provided with an operation space for operators to operate. The axial direction of the material barrel 11 is consistent with the height direction of the bracket 2. Clean pole 3 is cylindrical shaft-like, and clean pole 3 is used for contradicting in order to clean 11 inner walls of material section of thick bamboo with 11 inner walls of material section of thick bamboo, and in addition, 3 outer walls of clean pole can wrap up there is clean gauze, can increase the frictional force of clean pole 3 with material section of thick bamboo 11 like this, can not harm the inner wall of material section of thick bamboo 11 moreover. First drive arrangement sets up on support 2, and first drive arrangement is used for driving clean pole 3 and goes up and down to make clean pole 3 move for material section of thick bamboo 11, clear away the remaining material that is stained with on 11 inner walls of material section of thick bamboo. In this embodiment, the first driving device is a cylinder 4, and the cylinder body of the cylinder 4 is mounted on the bracket 2. In addition, in order to increase the cleaning force of the cleaning rod 3 on the material barrel 11, the melt flow rate meter can be further provided with a second driving device, the second driving device is used for driving the cleaning rod 3 to rotate, so that the cleaning rod 3 can rotate relative to the material barrel 11 in the process of stretching relative to the material barrel 11, friction is increased, and the side wall of the material barrel 11 is cleaned more fully. In order to realize the function of driving the cleaning rod 3 to rotate by the second driving device, the second driving device is a motor 6, a box body 5 is further arranged for conveniently installing the motor 6, and the box body 5 can be a cuboid. The case 5 is used to house a motor 6. As shown in fig. 2, the box body 5 is hinged with a door body, and one end of the box body 5 is connected with the piston end of the cylinder 4, so that the cylinder 4 can drive the box body 5 to lift, and the motor 6 in the box body 5 is driven to lift. And the one end of cleaning rod 3 stretches into the other end of box body 5 to be connected with the output of motor 6, so can drive cleaning rod 3 and go up and down when motor 6 goes up and down, motor 6 can drive cleaning rod 3 and rotate in addition, makes cleaning rod 3 can rotate at the in-process that goes up and down. In addition, in order to prevent the cylinder 4 from being damaged due to deviation of the path during the lifting of the box body 5, the side wall of the box body 5 is provided with a protrusion 51, and the protrusion 51 may be a cylindrical rod shape. In the present embodiment, the protrusion 51 is screwed with the case 5. Correspondingly, the bracket 2 is provided with a guide groove 21, and the guide groove 21 is in a long strip shape. The longitudinal direction of the guide groove 21 coincides with the height direction of the holder 2. The protrusion 51 is adapted to be inserted into the guide groove 21, and the protrusion 51 is movable along the length direction of the guide groove 21. In addition, the guide groove 21 is detachably provided with a stopper projection 22, and the stopper projection 22 is adapted to abut against the protrusion 51. Specifically, as shown in fig. 3, the limiting protrusion 22 is a rectangular parallelepiped protrusion, and the limiting protrusion 22 is provided with a threaded hole 221. The melt flow rate meter further comprises a bolt 8, and when the limit projection 22 is installed, the bolt 8 is inserted through the threaded hole 221, and the bolt 8 is abutted against the bottom of the guide groove 21. Spacing lug 22 can prevent effectively that box body 5 from excessively going up and down to lead to box body 5 and main part 1 collision, and bolt 8 can contradict with the different positions of guide way 21 moreover to adjust spacing lug 22's position, like this can adapt the not box body 5 of the different length of clean pole 3 and co-altitude not, more nimble.

In addition, as shown in fig. 1 and 2, in order to prevent the cylinder 4 from being damaged due to the mass of the box 5 and the motor 6, the melt flow rate meter is further provided with a rotating support plate 7, the rotating support plate 7 is rectangular plate-shaped, the rotating support plate 7 is rotatably disposed on the bracket 2, in this embodiment, one end of the rotating support plate 7 is hinged to the bracket 2, the rotating support plate 7 is L-shaped to prevent the rotating support plate 7 from abutting against the cleaning rod 3, and L-shaped plate can avoid the cleaning rod 3, when the rotating support plate 7 rotates to a supporting position (the position of the rotating support plate 7 in fig. 1), the surface of the rotating support plate 7 far away from the bottom of the bracket 2 abuts against the bottom surface of the box 5 to provide a supporting force for the box 5 to relieve the pulling force of the cylinder 4, and when the cleaning rod 3 needs to be lifted, the rotating support plate 7 can be rotated away from the supporting position, namely, the position of the rotating support plate 7 in fig. 2.

The working process and the implementation principle of the embodiment are as follows: when the side wall of the material barrel 11 of the melt flow rate instrument needs to be cleaned, the motor 6 can be driven to rotate the cleaning rod 3, then the cylinder 4 is driven, the cylinder 4 drives the box body 5 with the motor 6 to ascend and descend, so that the cleaning rod 3 connected with the motor 6 is driven to move relative to the side wall of the material barrel 11, and residual materials adhered to the side wall of the material barrel 11 are removed. In this engineering, the arch 51 of box body 5 is pegged graft with guide way 21, and guide way 21 can lead to box body 5, and skew when preventing box body 5 to move, the setting of spacing lug 22 can prevent in addition that box body 5 excessive movement from leading to box body 5 and main part 1 collision. After the cleaning is completed, the rotary supporting plate 7 is rotated to the supporting position (the position of the rotary supporting plate 7 in fig. 1), so that the rotary supporting plate 7 provides a supporting force for the box body 5 and the motor 6, and the stress of the cylinder 4 is reduced.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
