[0018] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0019] Example 1

[0020] like Figure 1-3 As shown, the automatic cleaning device for floating cargo on the tail drum includes a cleaning mechanism 1 and a foreign matter intrusion prevention mechanism 2. The cleaning mechanism 1 is installed on one side of the front end of the tail drum 3, and the foreign matter intrusion prevention mechanism 2 is installed at the front end of the cleaning mechanism 1.

[0021] The cleaning mechanism 1 includes a shell 101 with an opening at the top. The shell 101 is made of metal and is installed on a frame. The side wall of the shell 101 close to the tail drum 3 is inclined upward and provided with a cleaning blade 102. The top of the cleaning blade 102 is close to the surface of the tail drum 3, and the cleaning blade 102 is used to clean the material on the surface of the tail drum 3; an auger 103 is arranged in the shell 101, and both ends of the rotating shaft of the auger 103 are rotatably connected to the frame and one end located in the output direction of the auger 103 extends out of the frame to connect to a driven gear 104, and the driven gear 104 is connected to the driving gear 301 of the tail drum 3 through a driving chain 105. The auger 103 extending out of the frame is provided with a protective cover 4, and a discharge port 5 is opened below the protective cover 4.

[0022] The cleaning blade 102 is inclined at 50°-70°, and the distance between the top of the cleaning blade 102 and the tail drum 3 is 1-6 mm; this is conducive to cleaning the material on the surface of the tail drum 3 so that it falls into the shell 101 and is then output through the auger 103.

[0023] The cleaning blade 102 is made of a steel plate or an iron plate with a thickness of not less than 1 cm, has a high structural strength, is not easy to deform, and has a good cleaning effect.

[0024] Furthermore, a support frame 6 is installed on the side wall of the housing 101 away from the tail drum 3, and a spray device is provided on the support frame 6. The spray device includes a spray pipe 7 arranged along the length direction of the tail drum 3. One end of the spray pipe 7 is closed and the other end is connected to the water inlet pipe. A plurality of spray heads 8 are arranged at intervals on the spray pipe 7. The spray heads 8 are tilted downward to the surface of the tail drum 3. If the cargo is too sticky, the spray device is turned on for cleaning to improve the cleaning effect.

[0025] The above-mentioned foreign body intrusion prevention mechanism 2 includes a protective plate 201, which is installed above the conveyor belt 9. The bottom end of the protective plate 201 is spaced a set distance from the conveyor belt 9. The top of the protective plate 201 is connected to the mounting plate 202 by bolts. The two ends of the middle part of the mounting plate 202 are provided with rotating shafts that are rotatably connected to the frame through a rotating bearing seat 203. A stroke sensor 204 is provided on the upper side of the mounting plate 202 away from the tail drum 3. The stroke sensor 204 is electrically connected to the controller. After the mounting plate 202 rotates, the upper part contacts the probe of the stroke sensor 204. When a large piece passes over and falls into the conveyor belt 9, the protective plate 201 is pushed to rotate the mounting plate 202, and the top of the mounting plate 202 contacts the stroke sensor 204. The stroke sensor 204 transmits a signal to the controller to control the timely shutdown to prevent the large piece from falling into the bottom belt and damaging the equipment.

[0026] Furthermore, a cleaner 10 is provided at the front end of the above-mentioned foreign body intrusion prevention mechanism 2. The cleaner includes a baffle and a belt installed at the bottom of the baffle. The bottom end of the belt contacts the conveying belt 9. The baffle is tilted and forms an angle of 70°-80° with the conveying direction.

[0027] Working principle: When the belt conveyor is running, the cleaning blade 102 cleans the material on the surface of the tail roller 3 and drops it into the shell 101. The drive chain 105 transmits the power, and the auger 103 rotates synchronously to output the floating goods at the tail and discharge them through the discharge port 5. If the goods are too sticky, turn on the spray device for cleaning. When a large piece of goods passes over the cleaner, the equipment can be stopped urgently through the anti-foreign matter intrusion mechanism 2 to prevent them from falling into the bottom belt and damaging the equipment.

[0028] The device is easy to transform and can be processed according to the size of the existing tail space of the belt conveyor equipment. The tail roller is equipped with a gear drive without adding new power equipment. It not only solves the problem that the staff currently uses shovels to clean and there is a risk of being drawn into the tail roller 3, but also reduces the risk of cargo being wrapped around the tail roller 3, reduces belt deviation and wear, and prevents foreign matter from passing over the sweeper 10 and falling onto the bottom belt surface to damage the equipment.

[0029] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
