Description

Technical Field

[0001] The invention relates to the technical field of coal conveying belt cleaning, in particular to a belt scraper and a water scraper cleaner. Background Art

[0002] The existing fuel coal conveyor belts with water scraping function are mostly installed in the return section of the belt, which can only scrape off the coal slime or water carried in the return section, but cannot remove the water and coal slime on the working surface. In addition, the joint between the general water scraper and the belt is relatively hard, and it is easy to scratch the belt if it is close to the belt, and some coal water cannot be scraped clean if it is far away. As a result, a large amount of flushing water and coal slime will be attached to the working surface of the belt when flushing or unloading sticky and wet coal, which will cause the belt to stick and wet when loading coal, and it is very easy to block the coal drop tube. In addition, the water in the coal will flow out of the pipe belt during the long-distance coal loading process, polluting the ground, and in serious cases, it will cause environmental incidents. .

[0029] Preferably, the cleaning body 101 removes debris on the surface of the belt by contacting the belt.

[0030] Furthermore, the oil hole 102 passes through one side of the cleaning body 101 , and a plurality of oil holes 102 are arranged in an array.

[0031] Preferably, the oil guide member 103 stores solid lubricant inside, and the solid lubricant is transferred through the oil guide member 103 and then released through the oil hole 102 .

[0032] Preferably, the oil hole 102 opens in a direction opposite to the running direction of the belt, so that the lubricant is applied to the belt surface through the movement of the belt itself.

[0033] Preferably, the switch element 104 in the present invention is mechanically controlled, the switch element 104 is elastically connected inside the cleaning body, and the length of one end of the switch element 104 is slightly greater than the overall length of the cleaning body 101 .

[0034] In summary, when the cleaning body 101 is about to come into contact with the belt, part of the structure of the switch 101 contacts the belt surface first and retracts into the cleaning body 101, so that the oil hole 102 is connected with the oil guide 103, and the solid lubricant in the oil guide 103 is discharged. The lubricant is applied to the surface of the belt through the movement of the belt itself, and the debris on the belt surface is removed through the cleaning body 101.

[0035] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, further provides a belt scraper. The cleaning body 101 includes a blade body 101a and a blade head 101b arranged on the outer wall of the blade body 101a, and an oil hole 102 runs through the blade body 101a and the blade head 101b.

[0037] Preferably, the blade head 101b is based on the structure of the coal plow, and the length of the plow blade is increased, and the edge of the plow blade is designed to be a polyester amine material, and a special self-lubricating coating is applied to the surface of the scraper head. This coating can be a polymer material containing solid lubricants, such as polytetrafluoroethylene (PTFE), molybdenum disulfide (MoS2), etc. These solid lubricants can form a lubricating film on the surface when the scraper head rubs against the belt, effectively reducing the friction coefficient.

[0038] A first through hole 101d is formed at the bottom of the cutter head 101b, a receiving groove 101c is formed inside the blade body 101a, an oil guide member 103 is disposed inside the receiving groove 101c, a positioning frame 101e is disposed inside the receiving groove 101c, and the positioning frame 101e is fixedly connected to the blade body 101a.

[0039] Preferably, the first through hole 101d has an angle with the moving direction of the belt. Depending on the position of the cutter head 101b, when the cutter head 101b is perpendicular to the belt, that is, when the cutter head 101b contacts the belt surface, the first through hole 101d is perpendicular to the moving direction of the belt.

[0040] An oil inlet 105 is disposed at one end of the oil guide member 103 . The oil inlet 105 is communicated with the oil guide member 103 . A first oil outlet hole 103 a is formed on the oil guide member 103 .

[0043] The valve cover 104b is slidably disposed on the outer wall of the oil guide member 103, and the valve cover 104b is disposed below the positioning frame 101e. A first elastic member 104d is disposed between the valve cover 104b and the positioning frame 101e, and a second elastic member 104e is disposed between the valve cover 104b and the cutter head 101b.

[0044] Preferably, the first elastic member 104d and the second elastic member 104e are both compression springs. The positioning frame 101e is fixedly disposed inside the blade body 101a. The trigger rod 104a is cylindrical in this embodiment, and a chamfer is provided on the side away from the blade head 101b, which helps to reduce the wear on the belt when the trigger rod 104a contacts the end face of the belt.

[0045] The second oil outlet hole 104 c is movably matched with the first oil outlet hole 103 a , and the second oil outlet hole 104 c is also movably matched with the oil hole 102 .

[0046] Preferably, when the trigger rod 104a is completely retracted into the first through hole 101d by contacting the belt, the axes of the second oil outlet hole 104c, the first oil outlet hole 103a and the oil hole 102 are collinear, and the liquid in the oil guide member 103 can be discharged from the oil guide member 103 to the belt surface.

[0047] In summary, when it is necessary to scrape or clean the belt surface, the cutter head 101b is lowered to gradually approach the belt surface. At this time, the axis of the second oil outlet hole 104c is not colinear with the axis of the first oil outlet hole 103a, the axis of the second oil outlet hole 104c and the oil hole 102 are not colinear, and the first oil outlet hole 103a and the oil hole 102 are colinear. As the cutter head 101b is below, the trigger rod 104a contacts the belt surface.

[0055] The support plate 203c is perpendicular to the vertical bracket 202a, and the frame 203b is hinged on the support plate 203c and the vertical bracket 202a. The frame 203b can be rotated to move away from or close to the support plate 203c, that is, to raise or lower the height of the frame 203b.

[0056] The working member 204 includes a belt 204a and rollers 204b.

[0057] The roller 204b is rotatably arranged inside the frame 203c, and the belt 204a is located on the surface of the roller 204b. The belt 204a is driven to move by the rotation of the roller 204b.

[0058] Furthermore, a control box is provided outside the wiper and sweeper for controlling the motor 202a.
