Description

Technical Field

[0001] This invention belongs to the technical field of plate feeders, specifically relating to a plate feeder for a crusher. Background Technology

[0002] A plate feeder is a type of continuous material conveying machinery used to continuously and evenly feed and transfer materials to crushers, conveyors, or other working machinery along a horizontal or inclined direction. In traditional plate feeders, the structure of the conveying plate supporting the ore is in a horizontal state. This causes the conveyed ore to be transported into the processing device in a relatively dispersed manner, and it is easy for it to splash out from both sides of the feed inlet of the processing device, which not only causes waste but also easily leads to safety accidents.

[0003] The document with authorization announcement number CN114749263B discloses an intelligent medium-sized plate feeder with adjustable feeding angle, including a frame. A conveyor belt is installed inside the frame. The two ends of the conveyor belt are rotatably connected to the frame by multiple limiting rollers. A force-bearing area is set on the upper part of the conveyor belt. A support assembly is located inside the force-bearing area. The support assembly includes a drive roller rotatably connected to the upper surface of the inner wall of the conveyor belt near the force-bearing area. A rotating rod is fixedly connected to the drive roller. A bevel gear is fixedly connected to the end of the rotating rod away from the drive roller. A collar is rotatably connected to the outer wall of the rotating rod. A lifting platform is rotatably connected to the outer wall of the collar through a rotating shaft. The support assembly is mirror-arranged with two sets of bevel gears on the two rotating rods of the two sets meshing with each other. An adjustment device for adjusting the vertical position of the lifting platform is also provided inside the frame.

[0004] However, the above-mentioned device still has the following drawbacks: when adjusting the height of the rotating rod, the device relies entirely on two bevel gears to complete the transmission between the two drive rollers. The force between the bevel gears is large, the wear is large, the service life of the device is short, and replacing the bevel gears is not only difficult but also costly. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide a plate-type feeding device for crushers. By setting a support plate at the lower end of the conveyor belt, the conveyor belt maintains a controllable deformation range under stress, which not only reduces the risk of ore falling from both sides of the conveyor belt, but also features a simple structure and convenient installation. At the same time, the angle adjustment structure in this device is not directly connected to the conveyor belt, thereby avoiding the installation of complex transmission structures at the transmission belt and improving the service life of the device.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A plate-type feeding device for a crusher includes a frame, two drive rollers disposed at both ends of the frame, and a conveyor belt disposed on the two drive rollers. The conveyor belt is composed of an upper connecting belt and a lower connecting belt. A support unit is disposed in the space between the upper connecting belt and the lower connecting belt. The support unit includes a support plate fixedly installed on the frame and located at the lower end of the upper connecting belt, and two adjusting plates hinged to both sides of the support plate and located at the side ends of the upper connecting belt.

[0008] As a further preferred embodiment of the present invention, the support plate includes a plurality of first tubes that are parallel to each other and distributed along the conveyor belt conveying direction, a connecting shaft disposed at the end of the first tube, a first external threaded segment disposed on the connecting shaft, and a first internal threaded ring connected to the first external threaded segment; two adjacent first tubes are connected by a connector, the connector including a connecting plate and two mounting holes disposed on the connecting plate for passing through the two connecting shafts respectively; the first internal threaded ring is used to limit and fix the connecting plate.

[0009] As a further preferred embodiment of the present invention, the support plate further includes a mounting rod disposed on the outermost first tube or connecting shaft, and the frame is provided with a seat for fixing the mounting rod.

[0010] As a further preferred embodiment of the present invention, the seat includes a body, a through hole disposed on the body and for passing through the mounting rod, a second external threaded section disposed on the mounting rod, and a second internal threaded ring connected to the second external threaded section.

[0011] As a further preferred embodiment of the present invention, the support unit further includes a fixing member installed on the frame and located at the lower end of the support plate, the fixing member comprising a plurality of second tubes arranged in parallel and distributed along a direction perpendicular to the conveyor belt conveying direction.

[0012] As a further preferred embodiment of the present invention, one side of the adjusting plate is hinged to the outermost side of the first tube body, and the other side is a free end; the frame is provided with a support member connected to the lower surface of the adjusting plate near the free end.

[0013] As a further preferred embodiment of the present invention, the support member includes a base plate disposed on the frame, a fixing block disposed on the base plate, a vertical rod disposed on the fixing block, a first perforated ear plate disposed on the vertical rod, a second perforated ear plate disposed on the lower surface of the adjusting plate, and a support rod with both ends respectively hinged to the first perforated ear plate and the second perforated ear plate.

[0014] As a further preferred embodiment of the present invention, the base plate is provided with a track perpendicular to the conveyor belt conveying direction, and a sliding block disposed at the lower end of the fixed block and slidably connected to the track.

[0015] As a further preferred embodiment of the present invention, the frame is provided with a drive cylinder for sliding the fixed block along the track.

[0016] As a further preferred embodiment of the present invention, the transmission roller is provided with a limiting ring for limiting the position of the conveyor belt.

[0017] As a further preferred embodiment of the present invention, a dust collection box located at the lower end of the lower connecting belt is provided on the frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By installing support plates at the lower end of the conveyor belt, the conveyor belt maintains a controllable deformation range under stress. This not only reduces the risk of ore falling from the sides of the conveyor belt, but also results in a simple structure and easy installation.

[0020] 2. The angle adjustment structure in this device is not directly connected to the conveyor belt, thus avoiding the installation of a complex transmission structure at the transmission belt and improving the service life of the device.

[0021] 3. The surface of the support plate used to support the conveyor belt in this device can change repeatedly, so that the gap between the ore and the gap between the ore and the conveyor belt will change multiple times during transportation, which is beneficial to the crushing of the ore and the screening and collection of impurities.

[0034] Example 1

[0035] This embodiment provides a plate-type feeding device for a crusher, including a frame 11, two drive rollers 12 disposed at both ends of the frame 11, and a conveyor belt disposed on the two drive rollers 12. The conveyor belt is composed of an upper connecting belt 13 and a lower connecting belt 14 connected end to end. The two drive rollers 12 are located inside both ends of the conveyor belt to enable the conveyor belt to rotate cyclically. The upper connecting belt 13 and the lower connecting belt 14 are elastic, and when ore is placed on the conveyor belt, the conveyor belt will deform under force, thereby forming a V-shaped or U-shaped structure.

[0036] In this embodiment, a support unit is provided in the space between the upper connecting belt 13 and the lower connecting belt 14. The support unit includes a support plate 21 fixedly installed on the frame 11 and located at the lower end of the upper connecting belt 13, and two adjusting plates 22 hinged to both sides of the support plate 21 and located at the side ends of the upper connecting belt 13.

[0037] It is worth noting that the support plate 21 is distributed along the conveyor belt's conveying direction and has a gap of 1-5 cm between it and the lower surface of the upper connecting belt 13. When the ore is placed on the conveyor belt, the conveyor belt will deform under stress. When the lower end of the conveyor belt contacts the support plate 21, the support plate 21 supports the conveyor belt, thereby improving the conveyor belt's load-bearing strength. Two adjusting plates 22 are hinged to both sides of the support plate 21, and the adjusting plates 22 are inclined and extend to the upper end of the upper connecting belt 13 to limit the ore and prevent it from falling from both sides of the conveyor belt. The inclination of the adjusting plates 22 is adjustable to accommodate ores of different sizes. The device for adjusting the adjusting plates 22 can adopt any structure in the prior art, so it will not be described in detail in this embodiment.

[0038] The feeding device provided in this embodiment works on the following principle: by setting a support plate at the lower end of the conveyor belt, the elastic conveyor belt can deform during ore transport to form a concave conveying structure, ensuring ore accumulation and reducing the risk of ore falling. It also controls the maximum deformation range of the conveyor belt and provides rigid support, improving the load-bearing capacity of the conveyor belt. When handling small volumes of ore, the slope of the adjusting plate 22 is larger; when handling large volumes of ore, the slope of the adjusting plate 22 increases to avoid the problem of ore not being transported along the conveyor belt if the two inclined plates directly support the ore.

[0039] The feeding device provided in this embodiment has the following advantages over existing devices: First, by setting a support plate at the lower end of the conveyor belt, the conveyor belt can maintain a controllable deformation range when subjected to force, reducing the risk of ore falling from both sides of the conveyor belt; Second, the angle adjustment structure is not directly connected to the conveyor belt, thereby avoiding the installation of a complex transmission structure at the transmission belt and improving the service life of the device.

[0040] Example 2

[0041] This embodiment optimizes the structure of the support board 21 based on embodiment 1, as follows:

[0042] The support plate 21 includes a plurality of first tubes 211 that are parallel to each other and distributed along the conveyor belt conveying direction, a connecting shaft 212 disposed at the end of the first tube 211, a first external thread section 213 disposed on the connecting shaft 212, and a first internal thread ring 214 connected to the first external thread section 213; two adjacent first tubes 211 are connected by a connector 215, the connector including a connecting plate 215a and two mounting holes 215b disposed on the connecting plate 215a for passing through the two connecting shafts 212 respectively; the first internal thread ring 214 is used to limit and fix the connecting plate 215a.

[0043] As a further preferred embodiment, the support plate 21 further includes a mounting rod 216 disposed on the outermost first tube 211 or connecting shaft 212, and the frame 11 is provided with a seat 217 for fixing the mounting rod 216.

[0044] As a further preferred embodiment, the drive roller 12 is provided with a limiting ring for restricting the position of the conveyor belt. This arrangement is to prevent the conveyor belt from slipping on the drive roller 12 when the angle of the adjusting plate 22 changes or the surface of the support plate 21 changes.

[0045] The support plate provided in this embodiment is preferably used when the lower surface of the conveyor belt is in contact with the support plate to further improve the load-bearing strength of the conveyor belt. The specific working principle is as follows: First, all the tubes 211 are connected in sequence by the connectors 215 to form a whole. The outermost tube is also fixed to the frame 11 by the connection of the mounting rod 216 and the seat 217 to complete the installation of the support plate 21. When the support plate 21 is not subjected to external force, the tubes 211 are at the same horizontal height and form a horizontal plane. The horizontal plane is in contact with the lower surface of the connecting belt without ore to support the connecting belt and keep it horizontal. After the ore is placed, both the connecting belt and the tubes 211 are subjected to force. The connecting belt deforms, and the connection angle between the two tubes 211 changes. The connecting belt is still in contact with the tubes, but it presents a V-shaped or U-shaped structure, thereby forming a conveying shape that is conducive to ore accumulation.

[0046] The advantage of the support plate provided in this embodiment is that the support plate is composed of multiple tubes that are hinged together. The angle between the tubes changes when subjected to force, but the tubes themselves are still rigid structures. Therefore, compared with the conveyor belt, its load strength is greatly improved.

[0047] Example 3

[0048] This embodiment optimizes the structure based on embodiment 2, as follows:

[0049] The support unit also includes a fixing member 23 mounted on the frame 11 and located at the lower end of the support plate 21. The fixing member includes a plurality of parallel second tubes distributed perpendicular to the conveyor belt conveying direction. This arrangement limits the maximum deformation range of the support plate and further improves the load-bearing capacity.

[0050] As a preferred embodiment, the second tube is rotatably connected to the frame 11 to reduce friction with the support plate and improve the service life of the device.

[0051] Example 4

[0052] This embodiment optimizes the structure based on embodiment 2, as follows:

[0053] The seat 217 includes a body 217a, a through hole 217b disposed on the body 217a and for passing through the mounting rod 216, a second external thread section 217c disposed on the mounting rod 216, and a second internal thread ring 217d connected to the second external thread section 217c.

[0054] The advantage of this design is that the outermost tube 211 can be moved horizontally perpendicular to the conveyor belt direction by pushing and pulling the mounting rod 216. During this movement, the connection angle between the adjacent tubes 211 and the outermost tube 211 changes, creating an uneven surface on the support plate. This surface increases the gap between the ore and the connecting belt, promoting further collision and crushing of the ore, and also causing dust and other impurities to fall off. Continuously pulling the mounting rod causes the surface of the support plate to change continuously, further promoting ore crushing and impurity removal. When it is necessary to stop, simply pull the new inner threaded ring 217.

[0055] Understandably, in order to facilitate the falling of impurities, the conveyor belt has openings or a mesh structure, and the frame 11 is provided with a dust collection box 15 located at the lower end of the lower connecting belt 14 to collect the falling impurities.

[0056] Example 5

[0057] This embodiment provides a specific structure for adjusting the angle of the adjustment plate 22, as detailed below:

[0058] The adjustment plate 22 is hinged to the outermost end of the first tube 211 on one side, and the other side is a free end; the frame 11 is provided with a support member 24 connected to the lower surface of the adjustment plate 22 near the free end.

[0059] The support member 24 includes a base plate 241 disposed on the frame 11, a fixing block 242 disposed on the base plate 241, a vertical rod 243 disposed on the fixing block 242, a first perforated ear plate 244 disposed on the vertical rod 243, a second perforated ear plate 245 disposed on the lower surface of the adjusting plate 22, and a support rod 246 whose two ends are respectively hinged to the first perforated ear plate 244 and the second perforated ear plate 245.

[0060] As a further preferred embodiment, the base plate 241 is provided with a track 247 perpendicular to the conveyor belt conveying direction, a sliding block 248 disposed at the lower end of the fixed block 242 and slidably connected to the track 247, and a drive cylinder 249 provided to make the fixed block 242 slide along the track 247.

[0061] The working principle of this embodiment is as follows: The start-up drive cylinder 249 pushes the sliding block 248 to move on the track 247. The fixed block 242 on the sliding block 248 moves together, thereby driving the vertical rod 243 to move closer to / away from the conveyor belt. During this process, because the two ends of the support rod 246 are hinged to the upper end of the vertical rod 243 and the lower surface of the adjusting plate 22, the adjusting plate 22 rotates around the hinge point with the side end of the first tube 211 under the transmission of the support rod 246. When the vertical rod 243 moves closer to the conveyor belt, the slope of the adjusting plate 22 increases, which is suitable for small-volume ore. When the vertical rod 243 moves away from the conveyor belt, the slope of the adjusting plate 22 increases, which is suitable for large-volume ore.

[0062] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
