Description

Technical Field

[0001] This invention relates to the field of surface feeder technology, and more particularly to a self-cleaning surface feeder. Background Technology

[0002] The core function of a mobile surface feeder is to move flexibly on the ground and act as a mobile "throat" to continuously and smoothly transfer materials unloaded from front-end equipment (such as excavators, loaders, trucks, or mobile crushing plants) to the rear-end belt conveyor system. The surface feeder utilizes a plate chain conveyor, a tail sprocket assembly, and a drive unit to move the placed material from left to right, guiding it through the discharge port into the rear-end belt conveyor system for feeding.

[0003] Currently, the feeding technology and structure of mobile belt conveyors are relatively mature, and they can work well with surface feeders for material feeding. Mobile belt conveyors are typically integrated into a large, self-propelled or towable steel frame. The working mode of a surface feeder using a mobile belt conveyor is as follows: the surface feeder is located between the unloading point of the truck or loader and the mobile belt conveyor. Material is unloaded into the front receiving hopper of the surface feeder, falls onto the plate chain conveyor, and is stably supported and conveyed by the plate chain assembly and roller system inside the surface feeder. Finally, it is precisely ejected from the rear unloading arm into the mobile belt conveyor for subsequent transportation, achieving continuous transfer without secondary loading. This greatly reduces the turnaround distance of the truck or loader and improves system efficiency.

[0004] A search revealed that patent document CN116835260A discloses a tracked mobile surface feeder, including a tracked walking and rotating mechanism with a housing mounted on top. This invention, through its installation, allows operators to control the retraction of hydraulic rods supported by a support plate, as needed. The hydraulic rods pull the support seat via a winding rod, causing the ramp to rotate through a triangular frame, bringing the rollers into contact with the ground. This allows the ramp to rotate clockwise around the rotating rod, with the ground resisting the incline and the slope angle acting as a guide plate. The right side of the ramp aligns with the left side of the climbing ramp. Operators can then connect the ramp and the climbing ramp using fixing components, allowing dump trucks to travel along the ramp's incline to the top of the climbing ramp. The climbing ramp and the ramp, supported by reinforcing plates and connecting plates respectively, provide support for the dump trucks, enabling them to unload materials onto the top of a plate chain conveyor.

[0005] During the feeding process of the aforementioned surface feeder using a plate chain conveyor, the material is discharged after passing the top of the plate chain conveyor. A small portion of the material will adhere to the conveyor belt of the plate chain conveyor. This portion of the material will be scattered onto the inner wall of the box as the conveyor belt rotates. With the long-term transportation of materials, it will accumulate at the bottom of the box, affecting the feeding operation and increasing the difficulty of cleaning the equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a self-cleaning surface feeder that, through a material spillage and recovery mechanism in conjunction with a cleaning mechanism, can effectively transport materials spilled from the plate chain conveyor to a mobile belt feeder, preventing materials from accumulating in the conveyor frame.

[0007] The present invention adopts the following technical solution: A self-cleaning surface feeder includes a loader, a conveying device, and a mobile belt feeding device arranged from left to right. The conveying device includes a conveying frame, which is inclined and has an angle of 18° with the ground. A steel structure support is fixedly installed on the outside of the conveying frame. A walking device and an auxiliary moving mechanism are installed below the steel structure support. A traction rope is connected between the loader and the auxiliary moving mechanism. The conveyor frame is equipped with a plate chain conveyor mechanism and a material spreading and recycling mechanism inside. The upper end of the conveyor frame is open, and a material feeding frame is fixedly installed on the upper end of the conveyor frame. A drive device for driving the plate chain conveyor mechanism and the material spreading and recycling mechanism is installed on the upper right side of the conveyor frame. A discharge port is provided on the right end of the conveyor frame, which corresponds to the inlet of the mobile belt feeding device.

[0008] Optionally, the chain conveyor mechanism includes a chain plate section, symmetrically arranged first chain drive sections, and symmetrically arranged rotating shafts. The chain plate section is located between the two first chain drive sections and connected to the first chain drive sections. The rotating shafts pass through both sides of the conveyor frame and rotate in cooperation with it. Several baffles are provided on the outer side of the chain plate section. The chain plate section is composed of several chain plate components hinged together, and the baffles are fixed to the chain plate components.

[0009] Optionally, a third chain drive unit is provided on the outer side of the conveyor frame, and a sprocket connected to the first chain drive unit and the third chain drive unit is provided on the circumferential surface of the rotating shaft.

[0010] Optionally, guide rails are symmetrically fixed on both inner walls of the conveyor frame to support the first chain drive unit.

[0011] Optionally, the material recovery device includes a second rotating shaft and a second chain drive unit arranged symmetrically. The second rotating shaft passes through both sides of the conveying frame and rotates in cooperation with it. Several scrapers are connected between the two second chain drive units. The scrapers scrape and convey the material on the bottom surface of the conveying frame.

[0012] Optionally, two sets of guide rails are symmetrically fixed on the inner walls of both sides of the conveyor frame. The guide rails are used to support the second chain drive unit.

[0013] Optionally, the conveyor frame is equipped with several sets of cleaning mechanisms. The cleaning mechanism includes a rotating shaft, a support frame, and several knocking and cleaning components. The rotating shaft passes through both sides of the conveyor frame and rotates in cooperation with it. The support frame is fixed to the inner wall of the conveyor frame.

[0014] Optionally, the rotating shaft three is fixedly provided with the same number of cams as the knocking and clearing components on its circumferential surface within the conveying frame, and a sprocket connected to the third chain drive unit is fixedly provided on the rotating shaft three's circumferential surface extending beyond the conveying frame.

[0015] Optionally, the knocking removal component includes a support frame and a sliding shaft. The support frame is fixed to the support bracket. A base plate is fixedly installed on the lower end face of the support frame. A rubber plate is fixedly installed in the middle of the base plate. The sliding shaft passes through the upper end face of the support frame and slides in contact with it. The cam rotates to push the sliding shaft.

[0016] Optionally, a sliding plate that slides in the inner cavity of the support frame is fixedly installed on the lower end face of the sliding shaft. A return spring is symmetrically fixedly connected between the sliding plate and the bottom plate. A knocking block is fixedly installed on the middle surface of the sliding plate. An exhaust one-way valve is symmetrically fixedly installed on the bottom plate, and an intake one-way valve is symmetrically fixedly installed on the outer side of the support frame.

[0017] In summary, the present invention has the following beneficial effects: 1. In this invention, after the material is transported to the discharge port by the chain plate and the baffle plate, it enters the crushing mechanism below for crushing and then enters the belt roller feeding mechanism for conveying. At this time, a small part of the material will adhere to the chain plate and enter the interior of the conveying frame as the chain plate moves. Then, the scraper pushes the material scattered on the bottom surface of the conveying frame, so that the material enters the crushing mechanism through the discharge port until it falls into the belt roller feeding mechanism. This can effectively clean up the material scattered in the conveying frame and allow the material to re-enter the subsequent conveying system. 2. In this invention, the material attached to the surface of the chain plate is driven by the third chain transmission unit to rotate the third rotating shaft. The third rotating shaft drives the cam to rotate, which pushes the sliding shaft. The sliding shaft drives the sliding plate to slide in the support frame, which drives the striking block to strike the chain plate through the rubber plate, thereby separating the attached material from the chain plate and letting it fall into the inner bottom surface of the conveying frame. Then, it is pushed to the discharge port by the scraper. 3. In this invention, when the sliding plate is moving, it will compress the air in the support frame, causing the air to be discharged from the one-way valve to the hinge of the chain plate, thus blowing off the spilled material attached to the hinge. Then, the return spring drives the sliding plate to reset. During the reset process, the outside air re-enters the support frame through the one-way valve. This can effectively blow off the spilled material attached to the hinge of the chain plate to the inner bottom surface of the conveying frame, and then push it to the discharge port by the scraper.

[0020] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0021] Please see Figure 1-14 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: Example 1: like Figure 1-8 As shown, a self-cleaning surface feeder includes a conveying device 1, a mobile belt feeding device 3, and a loader 4, with the conveying device 1 disposed between the mobile belt feeding device and the loader 4. The conveying device 1 includes a conveying frame 11, which is inclined and has an angle of 18° with the ground. A steel structure support 22 is fixedly installed on the outside of the conveying frame 11 to support the conveying frame 11. A walking device 2 and an auxiliary moving mechanism 21 are installed below the steel structure support 22. Both the walking device 2 and the auxiliary moving mechanism 21 are tracked moving structures, and the walking device 2 itself has a drive source that can drive the conveying frame 11 and the auxiliary moving mechanism 21 to move. A traction rope is connected between the loader 4 and the auxiliary moving mechanism 21, and the loader 4, in conjunction with the walking device 2, drives the conveying frame 11 to move. The conveying frame 11 has a plate chain conveying mechanism 6 and a material spreading and recycling mechanism 7 installed inside the frame. The upper end of the conveying frame 11 is open. A feeding frame 12 is fixedly installed on the upper end of the conveying frame 11. The material is loaded by the loader 4 and then transferred to the feeding frame 12 by the loader 4. Then it enters the plate chain conveying mechanism 6 for transportation. A drive device 5 for driving the plate chain conveyor mechanism 6 and the material spreading and recycling mechanism 7 is provided on the upper right side of the conveyor frame 11. The right end of the conveyor frame 11 is provided with a discharge port 13, which corresponds to the inlet of the mobile belt feeding device 3. The material is transported to the discharge port 13 by the plate chain conveyor mechanism 6 and then enters the mobile belt feeding device 3. The mobile belt feeding device 3 includes a movable steel structure frame 31, a crushing mechanism 32, and a belt roller feeding mechanism 33. The movable steel structure frame 31 supports the crushing mechanism 32. The belt roller feeding mechanism 33 is located below the crushing mechanism 32. The material is transported to the crushing mechanism 32 through the plate chain conveyor 6 for crushing and then enters the belt roller feeding mechanism 33 below for conveying. The drive unit 5 includes two three-phase asynchronous motors, the output ends of which are connected to the plate chain conveyor mechanism 6 and the material spreading and recycling mechanism 7, respectively.

[0022] The aforementioned loader 4, drive unit 5, walking device 2, auxiliary moving mechanism 21, and mobile belt feeding device 3 are all existing technologies and will not be described in detail here.

[0023] like Figure 4-8 As shown, in this embodiment, the plate chain conveying mechanism 6 includes a chain plate part 62, a symmetrically arranged first chain drive part 61, and a symmetrically arranged rotating shaft 64. The chain plate part 62 is disposed between the two first chain drive parts 61 and connected to the first chain drive parts 61, and the chain plate part 62 is driven to move by the first chain drive parts 61. One end of the right-side rotating shaft 64 is connected to the output end of the three-phase asynchronous motor. Both ends of the rotating shaft 64 pass through the two sides of the conveying frame 11 and bearing components are provided on the extended circumferential surface. The outer side of the conveying frame 11 is provided with mounting grooves for fixing the bearing components. The rotating shaft 64 is fixed to the inner ring of the bearing component. A baffle frame 14 is symmetrically fixed inside the conveying frame 11. The baffle frame 14 is located at the position of the first chain drive part 61 and blocks the first chain drive part 61 to prevent the material from falling directly onto the first chain drive part 61 and affecting the movement of the first chain drive part 61.

[0024] like Figure 4 As shown, in this embodiment, a third chain drive unit 8 is provided on the outer side of the conveying frame 11, and a sprocket connected to the first chain drive unit 61 and the third chain drive unit 8 is provided on the circumferential surface of the rotating shaft 64. The rotating shaft 64 on one side is driven to rotate by the driving device 5, and then the first chain drive unit 61 and the third chain drive unit 8 are driven to move by the sprocket. The first chain drive unit 61 drives the chain plate unit 62 to move.

[0025] like Figure 7-8 As shown, in this embodiment, a plurality of baffle plates 63 are provided on the outer side of the chain plate part 62. The chain plate part 62 is composed of a plurality of chain plate components 621 hinged together, and the baffle plates 63 are fixed to the chain plate components 621. The material enters the surface of the chain plate 621 through the feeding frame 12, and then is transported by the cooperation of the chain plate 621 and the baffle plate 63.

[0026] like Figure 8 As shown, in this embodiment, guide rails 65 are symmetrically fixed on both inner walls of the conveying frame 11. The guide rails 65 are used to support the first chain drive unit 61 and ensure that the first chain drive unit 61 can move stably.

[0027] like Figure 5-8 As shown, in this embodiment, the material spreading and recycling device mechanism includes two symmetrically arranged rotating shafts 73 and a second chain drive unit 71. The two ends of the rotating shaft 73 pass through the two sides of the conveying frame 11 and bearing components are also provided on the extended circumferential surface. The outer side of the conveying frame 11 is provided with mounting grooves for fixing the bearing components. The rotating shaft 73 is fixed to the inner ring of the bearing component. The second shaft 73 on the right side is connected to the output end of another three-phase asynchronous motor. The second shaft 73 is driven to rotate by the drive device 5, and the rotation directions of the first shaft 64 and the second shaft 73 are opposite.

[0028] like Figure 5-8 As shown, in this embodiment, a number of scrapers 72 are connected between the two second chain drive units 71. The scrapers 72 are driven by the second chain drive units 71 to move, so that the scrapers 72 push the material on the bottom surface of the conveying frame 11 to the discharge port 13, and can effectively scrape and clean the bottom surface of the conveying frame 11. Two sets of guide rails 74 are symmetrically fixed on the inner walls of both sides of the conveyor frame 11. The guide rails 74 are used to support the second chain drive unit 71 and ensure that the second chain drive unit 71 can move stably.

[0029] Specifically, after the material is transported to the discharge port 13 via the chain plate 621 and the baffle plate 63, it enters the crushing mechanism 32 below for crushing and then enters the belt roller feeding mechanism 33 for conveying. At this time, a small portion of the material will adhere to the chain plate 621. As the chain plate 621 moves, it enters the interior of the conveying frame 11. Then, the scraper 72 pushes the material scattered on the bottom surface of the conveying frame 11, so that the material enters the crushing mechanism 32 through the discharge port 13, until it falls into the belt roller feeding mechanism 33.

[0030] Example 2: Based on Embodiment 1, in order to further remove the spilled material attached to the surface and hinge of the chain plate 621, several sets of cleaning mechanisms 9 are provided in the conveyor frame 11. The cleaning mechanisms 9 are used to knock and blow the chain conveyor 6 to separate the attached material and prevent the material from accumulating on the chain conveyor 6. The separated material is pushed back to the discharge port 13 by the spilled material recovery mechanism 7 below, and then enters the mobile belt conveyor 3 for transportation.

[0031] like Figure 10-14 As shown, in this embodiment, the cleaning mechanism 9 includes a rotating shaft 91, a support frame 93, and several knocking cleaning components 94; The two ends of the rotating shaft 91 pass through the two sides of the conveying frame 11 and bearing components are also provided on the extended circumferential surface. The outer side of the conveying frame 11 is provided with mounting grooves for fixing the bearing components. The rotating shaft 91 is fixed to the inner ring of the bearing component. The rotating shaft 91 is fixedly provided with the same number of cams 92 as the knocking and clearing components 94 on the circumferential surface of the rotating shaft 91 located inside the conveying frame 11. A sprocket connected to the third chain drive part 8 is fixedly provided on the extended circumferential surface of the rotating shaft 91. The sprocket is driven to rotate by the third chain drive part 8, which in turn causes the rotating shaft 91 to drive the cams 92 to rotate. The rotating shaft 91 rotates synchronously with the rotating shaft 64. The support frame 93 is fixed to the inner wall of the conveyor frame.

[0032] like Figure 10-14 As shown, in this embodiment, the knocking removal component 94 includes a support frame 941 and a sliding shaft 942. The support frame 941 is fixed to the support frame 93. A base plate 944 is fixedly provided on the lower end surface of the support frame 941, and a rubber plate 945 is fixedly provided in the middle of the base plate 944. The sliding shaft 942 passes through the upper end face of the support frame 941 and slides in fit. The lower end face of the sliding shaft 942 is fixedly provided with a sliding plate 9421 that slides in the inner cavity of the support frame 941. A return spring 9422 is symmetrically fixedly connected between the sliding plate 9421 and the bottom plate 944. A striking block 9423 is fixedly provided on the middle surface of the sliding plate 9421. During the sliding process, the sliding shaft 942 drives the striking block 9423 to strike the rubber plate 945, causing the rubber plate 945 to deform and then strike the chain plate 621, knocking off the material attached to the chain plate 621. Then, the return spring 9422 drives the sliding plate 9421 to return to its original position. An exhaust check valve 9441 is symmetrically fixed on the base plate 944, and an intake check valve 943 is symmetrically fixed on the outer side of the support frame 941. When the sliding plate 9421 moves downward, it compresses the air inside the support frame 941, causing the air to be discharged from the outlet of the one-way valve 9441. This blows the material at the hinge of the chain plate 621 downward, and then pushes it through the scraper 72. Together with the striking block 9423, it can effectively clean the chain plate 621, preventing material from accumulating at the hinge and affecting the transmission of the chain plate 621.

[0033] The aforementioned intake check valve 943 and exhaust check valve 9441 are both existing technologies and will not be drawn or described in detail here.

[0034] The specific work process is as follows: The loader 4 and the traveling mechanism bring the conveyor frame 11 to the feeding position of the mobile belt feeding device 3, so that the discharge port 13 of the conveyor frame 11 corresponds to the feeding port of the crushing mechanism 32. Then the loader 4 loads and unloads the material. The material enters the chain plate 621 through the unloading frame 12. The first chain drive part 61 drives the chain plate part 62 to move, and the material is transported to the discharge port 13 position in conjunction with the material stop, and then enters the mobile belt feeding device 3. During the feeding process, some of the spilled material will fall back to the inner bottom surface of the conveyor frame 11, and some of the spilled material will adhere to the surface of the chain plate 621 and the hinge of the chain plate 621. The material that has retreated to the bottom of the conveyor frame 11 is driven by the second chain drive 71 to move the scraper 72, pushing this part of the material back to the outlet 13 and then into the mobile belt feeding device 3. The spilled material adhering to the surface of the chain plate 621 and the hinge of the chain plate 621 is driven by the third chain drive part 8 to rotate the rotating shaft 91. The rotating shaft 91 drives the cam 92 to rotate, which pushes the sliding shaft 942. The sliding shaft 942 drives the sliding plate 9421 to slide in the support frame 941. On the one hand, it drives the striking block 9423 to strike the chain plate 621 through the rubber plate 945. On the other hand, the sliding of the sliding plate 9421 squeezes the air in the support frame 941, so that the air is discharged from the exhaust one-way valve 9441 to the hinge of the chain plate 621 to blow off the spilled material adhering to the hinge. Then the return spring 9422 drives the sliding plate 9421 to return to its original position. During the return process, the outside air re-enters the support frame 941 through the intake one-way valve.
