A belt scraper and a squeegee cleaner

Abstract

This invention relates to the field of coal conveyor belt cleaning technology, specifically a belt scraper and a water-scraping cleaner. It includes a cleaning assembly comprising a cleaning body, an oil hole formed in the cleaning body, an oil guide communicating with the oil hole, and a switch controlling the communication between the oil guide and the oil hole. The beneficial effects of this invention are: the oil guide stores lubricant, which is gradually released during the scraping process, creating a continuous lubrication effect and preventing belt scratches. When the scraper head contacts the belt and begins operation, due to the surface coating and microstructure, the lubricant forms a uniform lubricating film on the contact surface. This lubricating film converts the sliding friction between the scraper head and the belt into internal friction between lubricant molecules, thereby greatly reducing friction. Simultaneously, the lubricant also cools and reduces wear, protecting the scraper head and belt from damage.

Description

Technical Field

[0001] This invention relates to the field of coal conveyor belt cleaning technology, and in particular to a belt scraper and a water scraper cleaner. Background Technology

[0002] Existing coal conveyor belts with water-scraping functions typically have scrapers installed on the return section of the belt. These scrapers can only remove coal sludge or water carried on the return section, failing to remove water and coal sludge from the working face. Furthermore, the joint between the scraper blade and the belt is usually quite hard; too close to the belt, it can easily scratch the belt, while too far away, some coal and water may not be completely removed. This results in a large amount of flushing water and coal sludge adhering to the working face during flushing or unloading sticky or wet coal. When loading coal, this causes coal to stick to the belt and become wet, easily clogging the coal chute. Moreover, water carried by the coal can leak from the conveyor belt during long-distance coal loading, polluting the ground and potentially causing environmental incidents. Summary of the Invention

[0003] In view of the aforementioned existing technical problems, the present invention is proposed.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a belt scraper, which includes a cleaning component, the cleaning component including a cleaning body, an oil hole opened in the cleaning body, an oil guide communicating with the oil hole, and a switch for controlling the communication between the oil guide and the oil hole.

[0005] In a preferred embodiment of the belt scraper of the present invention, the cleaning body includes a blade and a blade head disposed on the outer wall of the blade, and the oil hole penetrates the blade and the blade head.

[0006] As a preferred embodiment of the belt scraper of the present invention, the blade head is made of polyester ammonia material and the surface of the blade head is coated with a self-lubricating coating.

[0007] In a preferred embodiment of the belt scraper of the present invention, the blade head has a first through hole at its bottom, the blade body has a receiving groove inside, the oil guide is disposed inside the receiving groove, and a positioning frame is disposed inside the receiving groove, the positioning frame being fixedly connected to the blade body.

[0008] In a preferred embodiment of the belt scraper of the present invention, an oil inlet is provided at one end of the oil guide member, the oil inlet is connected to the oil guide member, and a first oil outlet is provided on the oil guide member.

[0009] In a preferred embodiment of the belt scraper of the present invention, the switching component includes a trigger rod slidably connected to the first through hole, a valve cover disposed on the end face of the trigger rod, and a second oil outlet hole opened on the outer wall of the valve cover.

[0010] In a preferred embodiment of the belt scraper of the present invention, the valve cover is slidably disposed on the outer wall of the oil guide member, the valve cover is disposed below the positioning frame, a first elastic member is disposed between the valve cover and the positioning frame, and a second elastic member is disposed between the valve cover and the cutter head.

[0011] In a preferred embodiment of the belt scraper of the present invention, the second oil outlet hole is movably engaged with the first oil outlet hole, and the second oil outlet hole is also movably engaged with the oil hole.

[0012] The beneficial effects of the belt scraper of the present invention are as follows: Lubricant is stored through the oil guide component and gradually released during the scraping process, forming a continuous lubrication effect. This prevents belt scratches. When the scraper head contacts the belt and begins operation, the lubricant forms a uniform lubricating film on the contact surface due to the surface coating and microstructure. This lubricating film converts the sliding friction between the scraper head and the belt into internal friction between lubricant molecules, thereby greatly reducing friction. Simultaneously, the lubricant also cools and reduces wear, protecting the scraper head and belt from damage.

[0013] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a squeegee cleaner, which includes a belt squeegee; and a main body assembly, the main body assembly including a connector connected to the cleaning body, a power component connected to the connector, a support component supporting the power component and the connector, and a working component disposed on the support component.

[0014] In a preferred embodiment of the squeegee cleaner of the present invention, the power component drives the connecting component to cause the cleaning body to contact or detach from the surface of the working part.

[0015] The beneficial effects of the scraper cleaner of this invention are as follows: Through the cooperation between the power component and the cleaning component, when there is no water or coal sludge on the conveyor belt working surface, the scraper is raised to avoid affecting the operation of the conveyor belt. When there is a large amount of water or coal sludge on the conveyor belt working surface, the scraper is lowered, and at the same time, the lower flat support roller is raised, allowing the scraper to unidirectionally cut across the entire cross section of the conveyor belt, thoroughly and promptly cleaning the water and coal sludge off the belt. This avoids clogging of the lower coal chute and contamination of the ground. Attached Figure Description

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, referring to Figures 1-2 This is the first embodiment of the present invention. This embodiment provides a belt scraper, including a cleaning assembly 100, which includes a cleaning body 101, an oil hole 102 opened in the cleaning body 101, an oil guide 103 communicating with the oil hole 102, and a switch 104 controlling the communication between the oil guide 103 and the oil hole 102.

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

[0030] Furthermore, the oil holes 102 penetrate one side of the cleaning body 101, and the oil hole array 102 is provided in multiple forms.

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

[0032] Preferably, the opening of the oil hole 102 faces the opposite direction of the belt rotation, so that the lubricant is applied to the belt surface by the movement of the belt itself.

[0033] Preferably, the switch 104 is mechanically controlled in this invention. The switch 104 is elastically connected inside the cleaning body, and the length of one end of the switch 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, the switch part 101 first contacts the belt surface and retracts into the cleaning body 101, so that the oil hole 102 connects with the oil guide 103, and the solid lubricant inside the oil guide 103 is discharged. The lubricant is then spread all over the belt surface by the movement of the belt itself, and the cleaning body 101 removes the debris from the belt surface.

[0035] Example 2, refer to Figures 1 to 7 This is a second embodiment of the present invention, which further provides a belt scraper. It includes a cleaning body 101 comprising a blade 101a and a blade head 101b disposed on the outer wall of the blade body 101a, with an oil hole 102 penetrating through the blade body 101a and the blade head 101b.

[0036] The cutter head 101b is made of polyester-amino acid material and has a self-lubricating coating on its surface.

[0037] Preferably, the cutter head 101b adopts the structure of a coal plow, increases the length of the plow blade, designs the edges of the plow blade to be made of polyester-amino acid material, and coats the surface of the cutter head with a special self-lubricating coating. This coating can be a polymer material containing solid lubricants, such as polytetrafluoroethylene (PTFE) or molybdenum disulfide (MoS2). These solid lubricants can form a lubricating film on the surface when the cutter head rubs against the belt, effectively reducing the coefficient of friction.

[0038] The cutter head 101b has a first through hole 101d at the bottom, and the cutter body 101a has a receiving groove 101c inside. The oil guide 103 is located inside the receiving groove 101c, and a positioning frame 101e is provided inside the receiving groove 101c. The positioning frame 101e is fixedly connected to the cutter body 101a.

[0039] Preferably, the first through hole 101d is at an angle to the belt movement direction. 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 is in contact with the belt surface, the first through hole 101d is perpendicular to the belt movement direction.

[0040] One end of the oil guide 103 is provided with an oil inlet 105, which is connected to the oil guide 103. The oil guide 103 is provided with a first oil outlet 103a.

[0041] Preferably, the oil guide 103 is a pipeline used to guide lubricant, oil, etc. from the oil inlet 105 to the first oil outlet 103a, and then discharge it to the belt surface through the oil hole 102.

[0042] The switch 104 includes a trigger rod 104a that is slidably connected to the first through hole 101d, a valve cover 104b disposed on the end face of the trigger rod 104a, and a second oil outlet hole 104c opened on the outer wall of the valve cover 104b.

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

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

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

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

[0047] In summary, when it is necessary to scrape and clean the belt surface, the cutter head 101b is lowered and gradually brought closer to the belt surface. At this time, the second oil outlet 104c is not collinear with the axis of the first oil outlet 103a, and the second oil outlet 104c is not collinear with the axis of the oil hole 102. The first oil outlet 103a and the oil hole 102 are collinear. As the cutter head 101b moves downward, the trigger rod 104a contacts the belt surface. Under the action of the two elastic elements, the trigger rod 104a slides along the outer wall of the oil guide 103, gradually making the axes of the second oil outlet 104c, the first oil outlet 103a, and the oil hole 102 collinear. Finally, the liquid in the oil guide 103 can be discharged from the oil guide 103 to the belt surface.

[0048] Example 3, referring to Figure 1 This is the third embodiment of the present invention, which further provides a squeegee cleaner. It includes a main body assembly 200, including a connector 201 connected to a cleaning body 101, a power component 202 connecting the connector 201, a support component 203 supporting the power component 202 and the connector 201, and a working component 204 disposed on the support component 203.

[0049] The power unit 202 drives the cleaning body 101 to contact or detach from the surface of the working part 204 via the drive connector 201.

[0050] Preferably, the cleaning body 101 is movably connected to the connector 201, the power component 201 is drivenly connected to the connector, the power component 201 is fixedly connected to the support 203, and the working part 204 is movably connected to the support 203.

[0051] In summary, through the coordination of the power components and cleaning components, when there is no water or coal sludge on the conveyor belt face, the wiper is raised to avoid affecting the belt's operation. When there is a large amount of water or coal sludge on the conveyor belt face, the wiper is lowered, and at the same time, the lower flat support rollers are raised, allowing the wiper to unidirectionally cut across the entire cross section of the belt, thoroughly and promptly cleaning the water and coal sludge off the belt. This prevents clogging of the downstream coal chute and contamination of the ground.

[0052] Example 4, refer to Figures 1 to 8 This is a fourth embodiment of the present invention, which further provides a squeegee cleaner. It includes a connector 201 comprising a first connecting frame 201a and a second connecting frame 201b, wherein the first connecting frame 201a and the blade 101a are hinged together.

[0053] The power component 202 includes a motor 202a and a transmission screw 202b, with the transmission screw 202b rotatably mounted on the first connecting frame 201a.

[0054] The support member 203 includes a vertical bracket 202a that is fixedly connected to the motor 202a. The lower end of the vertical bracket 202a is hinged to the second connecting frame 201b. Therefore, starting the motor 202a can drive the transmission screw 202b to rotate, causing the second connecting frame 201b to rotate and lift the cleaning component 100. The support member 203 also includes a support plate 203c and a frame 203b that is hinged to the vertical bracket 203a and the support plate 203c.

[0055] The support plate 203c is perpendicular to the vertical bracket 202a. The frame 203b is hinged to the support plate 203c and the vertical bracket 202a. The frame 203b can rotate, so that the frame 203b moves away from or closer to the support plate 203c, that is, the height of the frame 203b is raised or lowered.

[0056] The working component 204 includes a belt 204a and an idler roller 204b.

[0057] The idler roller 204b is rotatably mounted inside the frame 203c, and the belt 204a is located on the surface of the idler roller 204b. The belt 204a is moved by the rotation of the idler roller 204b.

[0058] Furthermore, a control box is installed on the outside of the wiper to control the motor 202a.

[0059] In summary, when the idler roller 204b rises, it lifts the belt 204a, ensuring close contact between the cutter head 101b and the belt 204a. A control box is provided locally. When there is no water or coal slurry on the working face of the belt 204a, the cutter head 101b is raised to avoid affecting the belt's operation. When there is a large amount of water or coal slurry on the working face of the belt 204a, the cutter head 101b is lowered, and simultaneously the lower flat support idler roller 204b is raised, allowing the cutter head 101b to unidirectionally cut across the entire cross section of the belt 204a, thoroughly and promptly removing the water and coal slurry from the belt 204a. This prevents blockage of the downstream coal chute and ground contamination.
