DETAILED DESCRIPTION

[0015] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0016] Combined with Figures 1 to 3 As shown, a crushing and cleaning screw conveyor comprises a crusher 1 and a conveyor body; the conveyor body comprises a U-shaped trough 2, the left end of the U-shaped trough 2 is provided with a sewage outlet 2c, and a feed inlet 2a connected to the crusher 1, and the right end thereof is provided with a discharge outlet 2b, and the upper end of the inner side of the U-shaped trough 2 is provided with two mutually symmetrical slide rails 2d; a cover plate 3, the cover plate 3 is openably arranged at the upper end of the U-shaped trough 2; an auger 4, the auger 4 is rotatably arranged in the U-shaped trough 2, and comprises an intermediate shaft 5 and spiral blades 6; the intermediate shaft 5 is hollow, and is provided with a plurality of flushing The nozzle 5a; the left end of the intermediate shaft 5 is provided with a rotary joint 5b connected to the inside thereof; the conveying motor 7, which is arranged at the right end of the U-shaped trough 2 and is drivingly connected to the right end of the intermediate shaft 5; a cleaning component, which is detachably mounted on the slide rail 2d and is used to clean the auger 4, and includes a slide 8 slidably mounted on the slide rail 2d, a control box 9 arranged at the upper end of the slide 8, a cleaning brush roller 10 arranged at the lower end of the slide 8, and two limit rollers 11 arranged at the lower end of the slide 8 and located on the left and right sides of the cleaning brush roller 10 respectively;

[0017] It should be noted that a long observation window is provided on the above-mentioned cover plate 3. When cleaning, the cover plate 3 is closed, and the operator can clearly see the position of the cleaning component so that it can be closed at any time; in addition, when cleaning, it is necessary to lower the speed of the conveying motor 7 so that the auger 4 rotates slowly to avoid the auger 4 rotating too fast and moving the cleaning component too fast, resulting in incomplete cleaning; in addition, when the equipment is normally crushing and cleaning plastics, the cleaning component is disassembled and not installed.

[0018] Combined with Figure 1 , 2 As shown, the lower end of the cleaning brush roller 10 abuts against the intermediate shaft 5, and the two sides thereof abut against the corresponding side edges of the spiral blade 6; the two limit rollers 11 also abut against the corresponding side edges of the spiral blade 6;

[0019] It should be noted that, as the intermediate shaft 5 rotates, the spiral blade 6 rotates accordingly, and then abuts against the limiting roller 11, and the limiting roller 11 pushes the entire slide 8 to move, and the entire cleaning component also moves accordingly.

[0020] Combined with Figure 1 , 2 As shown, the control box 9 is provided with a control host 9c, a power supply 9b, and a cleaning motor 9a, and the cleaning motor 9a is drivingly connected to the cleaning brush roller 10;

[0021] It should be noted that the control box 9 is made of waterproof material and has a certain degree of waterproofness. During cleaning, the flushing water sprayed by the flushing nozzle 5 a will not enter the control box 9 .

[0022] The plurality of flushing nozzles 5a are distributed at intervals along the rotation direction of the spiral blade 6 on the intermediate shaft;

[0023] It should be noted that the flushing nozzle 5 a is designed with a countersunk head, that is, after the flushing nozzle 5 a is installed, its head will not exceed the outer periphery of the central axis 5 .

[0024] Combined with Figure 1 , 3 As shown, a plurality of upper guide wheels 8a and lower guide wheels 8b are provided at the matching position of the slide seat 8 and the slide rail 2d. The lower guide wheels 8b are mounted on a guide wheel frame 8c. The guide wheel frame 8c is detachably mounted on the slide seat 8:

[0025] It should be noted that when installing the cleaning assembly, the entire cleaning assembly is directly placed on the slide rail 2d so that the upper guide wheel 8a cooperates with the corresponding slide rail 2d, and then the guide wheel frame 8a is installed so that the lower guide wheel 8b cooperates with the corresponding slide rail 2d.

[0026] During operation, the waste plastic first enters the crusher 1, and after being crushed by the crusher 1, enters the conveyor body from the feed port 2a. The auger 4 rotates continuously, carrying the crushed plastic upward until it reaches the discharge port 2b and is discharged from the discharge port 2b. It should be noted that the conveyor body is equipped with rinsing water. After the crushed plastic enters the conveyor body, it moves while being rinsed under the action of the auger 4.

[0027] When cleaning the inside of the conveyor body,

[0028] The first step is to turn off the crusher 1 and the conveying motor 7, open the drain port 2c, and drain the rinsing water in the U-shaped trough 2;

[0029] The second step is to open the cover plate 3 and install the cleaning assembly to the leftmost end of the slide rail 2d;

[0030] The third step is to start the cleaning motor 9a, close the cover plate 3, and supply water to the rotary joint 5b;

[0031] The fourth step is to adjust the direction of the conveying motor, restart the conveying motor 7 to make the auger 4 rotate, and as the auger 4 rotates, the cleaning component moves to the right along the direction of the slide rail 2d until it reaches the rightmost end; in this process, the cleaning brush roller 10 continuously brushes the intermediate shaft 5, the spiral blade 6 and the side wall of the U-shaped trough 2 of the auger 4, and the flushing nozzle 5a continuously flushes the auger 4, the inner side of the cover plate 3 and the inner wall of the U-shaped trough 2, and the cleaned dirt is discharged from the drain port 2c along with the water flow;

[0032] Step 5: When the cleaning component moves from the leftmost end to the rightmost end of the slide rail 2d, turn off the conveying motor 7, adjust the direction of the conveying motor 7, and then restart the conveying motor 7, so that the cleaning component moves from the rightmost end of the slide rail 2d to the left until it reaches the leftmost end of the slide rail 2d;

[0033] Step 6. Repeat steps 4 and 5 until the inside of the conveyor body is clean.

[0034] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
