Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A shearer spiral drum includes a shearer spiral drum 1, the shearer spiral drum 1 is arranged above the shearer rocker arm 7, a box body 5 is installed inside the shearer rocker arm 7, a water tank assembly 4 is installed at a position below the box body 5, a lifting water spraying assembly 6 is installed inside the box body 5 and at a position on one side of the top of the water tank assembly 4, a door panel assembly 8 is installed above the box body 5, and a drying treatment device 2 is arranged on one side of the shearer rocker arm 7. The shearer spiral drum 1 and the shearer rocker arm 7 are connected by a lifting lighting device 3.

[0023] Specifically, the drying treatment device 2 includes a heating box 21, a sprayer 22, a lifting assembly 23, a fan 25 and an electric heating rod 26. A heating box 21 is arranged on one side of the shearer rocker arm 7, a plurality of fans 25 are installed below the heating box 21, a plurality of electric heating rods 26 are installed inside the heating box 21, a plurality of sprayers 22 are installed on the side of the heating box 21 close to the shearer rocker arm 7, and the heating box 21 and the shearer rocker arm 7 are connected by a lifting assembly 23.

[0024] By adopting the above technical solutions, it enables the staff to perform a certain drying treatment on the washed shearer spiral drum 1 through the cooperation of structures such as the fan 25 and the electric heating rod 26 when needed, so as to better meet the working needs in different situations.

[0025] Specifically, the drying device 2 further includes a partition net 24, and the partition net 24 is installed below the air inlet end of the fan 25.

[0026] By adopting the above technical solution, the drum can prevent external impurities from entering the interior of structures such as the fan 25 through the partition net 24, thereby reducing the possibility of structures such as the fan 25 and the electric heating rod 26 being adversely affected and ensuring the normal progress of the work.

[0027] Specifically, the lifting assembly 23 includes an electric telescopic rod 231 and a lifting plate 232. The electric telescopic rod 231 is installed on one side of the shearer boom 7 close to the plurality of nozzles 22, and the electric telescopic rod 231 is connected to the heating box 21 through the lifting plate 232.

[0028] By adopting the above technical solution, the staff can adjust the height of structures such as each nozzle 22 to a certain extent through the cooperation of the electric telescopic rod 231 and the lifting plate 232 when needed, so as to better meet the needs in different situations.

[0029] When this embodiment is in use, when the shearer needs to use the drum, the staff can open the door panel assembly 8 on the box body 5, then manipulate the lifting and spraying assembly 6 to align with the shearer helical drum 1 above the shearer boom 7, then manipulate the water tank assembly 4 to send water to the lifting and spraying assembly 6, and the water is sprayed onto the shearer helical drum 1 to wash it. Then the staff closes the water tank assembly 4, retracts the lifting and spraying assembly 6 into the box body 5, closes the door panel assembly 8, and starts the electric telescopic rod 231 in the lifting assembly 23 of the drying device 2, thereby driving the lifting plate 232 to rise until each nozzle 22 is aligned with the shearer helical drum 1. Start each fan 25 and each electric heating rod 26. Each fan 25 sends the air filtered by the partition net 24 into the heating box 21, and then each electric heating rod 26 heats the air. The hot air blows from each nozzle 22 onto the shearer helical drum 1 to dry it. During the washing and drying process, the staff can manipulate the shearer helical drum 1 to rotate, and then the staff can use it through the shearer helical drum 1.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the lifting lighting device 3 includes a lead screw 31, a rotating plate 32 and a lifting frame 33. The lead screw 31 is installed below the shearer boom 7 through a bearing, the rotating plate 32 is installed below the lead screw 31, and the lifting frame 33 is installed on the outer side of the lead screw 31 at a position below the shearer helical drum 1 and outside the shearer boom 7 through a thread.

[0032] By adopting the above technical solution, the staff can adjust the height of the shearer helical drum 1 to a certain extent through the cooperation of structures such as the lead screw 31 and the lifting frame 33 when needed, so as to better meet the working needs in different situations.

[0033] Specifically, the lifting and lighting device 3 further includes a transparent box 34 and a lighting lamp 35. A transparent box 34 is installed between the shearer helical drum 1 and the lifting frame 33, and a lighting lamp 35 is installed inside the transparent box 34.

[0034] By adopting the above technical solution, the drum can be assisted in lighting by the lighting lamp 35 when needed, so as to better meet the needs in some cases of insufficient light, and thus ensure the normal progress of the work.

[0035] When this embodiment is in use, when it is necessary to adjust the height of the shearer helical drum 1, the staff rotates the rotating plate 32 in the lifting and lighting device 3, thereby driving the lead screw 31 to rotate. The lead screw 31 is threadedly connected to the lifting frame 33, and the inner width of the lifting frame 33 is equal to the outer width of the shearer arm 7. Therefore, the lead screw 31 drives structures such as the lifting frame 33 to move, and then adjusts the height of the shearer helical drum 1. When needed, the staff can start the lighting lamp 35 in the transparent box 34 for auxiliary lighting.

[0036] In the present utility model, the structures and principles of the shearer helical drum 1, the water tank assembly 4 composed of a high-pressure water pump, a water outlet hose, a water tank, a water inlet pipe and an external water pipe, the box body 5 and its upper structures, the lifting and spraying assembly 6 composed of a motor, a screw rod, a sleeve, a sliding cylinder, a guide rod, a spray pipe and a spray head, the shearer arm 7, and the door panel assembly 8 composed of a door panel, a first threaded hole and a bolt have been disclosed in a shearer helical drum convenient for cleaning with a Chinese patent application number of 202121813938.7. Its working principle is that the motor and the high-pressure water pump are electrically connected to an external controller through wires. After the shearer helical drum is used, coal slag is likely to remain on the cutting teeth of the drum. Therefore, it is necessary to clean the shearer helical drum. During use, first unscrew the bolt, then open the door panel and rotate it 180 degrees to the third threaded hole, and then screw the bolt in to fix the door panel at the rear of the box body. At this time, the outlet of the cleaning device is opened, and the controller controls the motor to rotate and drive the screw rod to rotate. At this time, because the guide rod and the sliding cylinder limit the rotation of the sleeve, the rotation of the screw rod will drive the sleeve to feed outward. At this time, the sliding cylinder will follow the sleeve and move on the guide rod. When the sleeve feeds until the entire spray pipe leaks out of the box body, the controller controls the motor to stop rotating. At this time, the controller controls the high-pressure water pump to pump the high-pressure water introduced from the external water pipe into the water tank into the water outlet hose and into the spray pipe, and spray out from the spray head. At this time, control the shearer helical drum to rotate, and the sprayed high-pressure water will clean the residual coal slag stains on the shearer helical drum, completing the entire cleaning process.

[0037] The working principle and usage process of the present utility model are as follows: When the shearer needs to use the drum, the staff can open the door panel assembly 8 on the box body 5, then manipulate the lifting and spraying assembly 6 to align with the shearer spiral drum 1 above the shearer boom 7, and then manipulate the water tank assembly 4 to supply water to the lifting and spraying assembly 6. The water is sprayed onto the shearer spiral drum 1, thereby flushing it. Then, the staff closes the water tank assembly 4, retracts the lifting and spraying assembly 6 into the box body 5, closes the door panel assembly 8, and starts the electric telescopic rod 231 in the lifting assembly 23 of the drying treatment device 2, thereby driving the lifting plate 232 to rise until each nozzle 22 aligns with the shearer spiral drum 1. Start each fan 25 and each electric heating rod 26. Each fan 25 sends the air filtered by the partition net 24 into the heating box 21, and then each electric heating rod 26 heats the air. The hot air blows from each nozzle 22 onto the shearer spiral drum 1, thereby performing a drying treatment on it. During the flushing and drying processes, the staff can manipulate the shearer spiral drum 1 to rotate, and then the staff can use it through the shearer spiral drum 1; When it is necessary to adjust the height of the shearer spiral drum 1, the staff rotates the rotating plate 32 in the lifting lighting device 3, thereby driving the lead screw 31 to rotate. The lead screw 31 is threadedly connected to the lifting frame 33, and the inner width of the lifting frame 33 is equal to the outer width of the shearer boom 7. Therefore, the lead screw 31 drives the lifting frame 33 and other structures to move, thereby adjusting the height of the shearer spiral drum 1. When necessary, the staff can start the lighting lamp 35 in the transparent box 34 for auxiliary lighting.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
