[0002] A chain conveyor is a highly efficient transmission device that uses a standard chain as the bearing surface and is driven by a motor reducer to transport materials horizontally or obliquely. In the existing technology, after the conveyor has been used for a long time, the material causes significant wear on the lower hopper, and the replacement of the lower hopper is relatively difficult.

[0003] In order to solve the above-mentioned problem of "it is difficult to replace the unloading hopper", it was found through search that: the application number is CN201922272335.X, which discloses a unloading device for a belt conveyor, including two support plates, which are respectively located on both sides of the conveying direction of the belt conveyor; unloading plates are detachably provided on the support plates, and limiting grooves are respectively provided on the surfaces of the two support plates close to each other, and the length direction of the limiting grooves is inclined towards the direction away from the belt conveyor, and the two ends of the unloading plate are respectively fixed with limiting blocks matching the limiting grooves along the length direction; a supporting eaves is fixed to the top of the limiting block, and when the limiting block is inserted into the limiting groove, the supporting eaves can rest against the top of the support plate.

[0004] However, the above-mentioned blanking plate needs to be lifted from above. Due to the height of the conveyor and the height of the support frame, a ladder or stepping stone is needed to raise the height of the staff to remove it. There is no fulcrum, which makes replacement inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide a material discharge mechanism for a chain conveyor to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A material unloading mechanism for a chain conveyor, comprising:

[0008] The support frame is fixed on both sides of the front end of the chain conveyor, and a blanking plate is installed in the support frame by plugging. The top of the support frame is provided with a fixing bolt, and the fixing screw passes through the threaded hole on the top of the support frame and is threadedly connected to the top of the blanking plate.

The space on the side of the fixing plate facing the front end of the chain conveyor is provided with a buffer plate, and the buffer plate is fixed between the support frames by a rotating shaft, and a spiral spring is provided in the rotating shaft for resetting the buffer plate. The bottom of the buffer plate has a buffer component to reduce the impact of falling materials to prevent damage to the chain plate.

[0009] Preferably, the buffer assembly includes a movable rod, which is bent 180°. One end of the movable rod is fixedly connected to the lower end surface of the bottom of the buffer plate, and the other end passes through a limiting ring in the fixed avoidance groove to reach the top of the fixed plate. The limiting ring is slidably connected in the avoidance groove.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figures 1 to 6 , the utility model provides a technical solution:

[0028] A material unloading mechanism for a chain conveyor, comprising:

[0029] The support frame 2 is fixed on both sides of the front end of the chain conveyor 1, and a blanking plate 3 is installed in the support frame 2 by plugging. The top of the support frame 2 has a fixing bolt 201, and the fixing screw passes through the top of the support frame 2 and is threadedly connected with the threaded hole 302 on the top of the blanking plate 3. There is a fixing rod 401 between the support frames 2 on both sides, and a fixing plate 4 is connected to the fixing rod 401. The space of the fixing plate 4 facing the front end of the chain conveyor 1 has a buffer plate 5, and the buffer plate 5 is fixed between the support frames 2 by a rotating shaft 6. A spiral spring 601 is provided in the rotating shaft 6 for resetting the buffer plate 5. The bottom of the buffer plate 5 has a buffer component for reducing the impact of falling materials to prevent damage to the chain plate.

[0030] In this embodiment, the material is poured into the blanking plate 3, and the material hits the chain plate directly, which is easy to damage the chain plate structure and increase the maintenance cost. Therefore, a buffer component is added between the support frames 2 on both sides. The front end of the buffer component is a fixed plate 4 fixed in the support frame 2, and the buffer plate 5 at the rear end is connected to the fixed plate 4 through a movable rod 7. The buffer plate 5 is along the rotating shaft 6, such as Figure 1 Rotate in direction A to make the material fall onto the chain conveyor 1.

[0031] When the material enters the blanking plate 3, the material slides down along the rear wall of the blanking plate 3 and contacts the buffer plate 5. Since the buffer plate 5 is connected by a rotating shaft 6 at one end, the buffer plate 5 will be pressed down by the material, and the spiral spring 601 inside the rotating shaft 6 will also be compressed. At this time, the movable rod 7 at the bottom of the buffer plate 5 will move as the buffer plate 5 is pressed down, and the other end of the movable rod 7 extends to the upper end of the fixed plate 4. At the same time, the bending spring 701 set on the movable rod 7, since one end of the bending spring 701 is connected to the bottom of the fixed plate 4 and the other end is fixedly connected to the bottom of the buffer plate 5, the bending spring 701 will also be compressed when the buffer plate 5 is pressed down (such as Figure 6 ), the restoring force generated by the compression of the bending spring 701 provides the buffer plate 5 with a force in the opposite direction of pressing down, thereby reducing the impact force of the material pressing down, and then the gap that opens allows the material to continue to slide onto the chain plate.

[0032] After the buffer plate 5 is pressed down, the material falls into the chain plate, and the buffer plate 5 loses the force of being pressed down, and is thus driven to recover by the spiral spring 601 inside the rotating shaft 6, and the bending spring 701 assists the spiral spring 601 in recovering.

[0033] Specifically, such as Figure 5 As shown, the buffer assembly includes a movable rod 7, which is bent 180°. One end of the movable rod 7 is fixedly connected to the lower end surface of the bottom of the buffer plate 5, and the other end passes through the limiting collar 403 in the avoidance groove 402 on the fixed plate 4 to reach the top of the fixed plate 4. The limiting collar 403 is slidably connected in the avoidance groove 402. When the movable rod 7 rotates with the buffer plate 5, the center of the movable rod 7 and the rotating shaft are not at the same point. When the buffer plate 5 rotates, the horizontal position of the movable rod 7 will also change, that is, the movable rod 7 slides in the avoidance groove 402, and since the limiting collar 403 is limited in the avoidance groove 402, the movable rod 7 passing through the limiting collar 403 is also limited in the avoidance groove 402.

[0034] Specifically, the movable rod 7 is provided with a bending spring 701 on its outer sleeve, one end of the bending spring 701 is fixed to the bottom lower end surface of the buffer plate 5, and the other end is fixed to the bottom lower end surface of the fixed plate 4 along the path of the movable rod 7.

[0035] In this embodiment, the fixing bolt 201 on the support frame 2 is used to fix the blanking plate 3 inserted into the support frame 2. When the blanking plate 3 needs to be removed, even if the fixing bolt 201 is loosened, the fixing bolt 201 will be stuck at the upper end of the threaded hole 302 due to gravity, affecting the withdrawal of the blanking plate 3. Therefore, a reset spring 203 is provided on the fixing screw. When the fixing bolt 201 is loosened, the reset spring 203 is reset, thereby lifting the fixing bolt 201 to prevent affecting the withdrawal of the blanking plate 3.

[0036] Specifically, such as Figure 4 As shown, a return spring 203 is sleeved on the fixing bolt 201 , and the lower end surface of the top of the support frame 2 has a first hook 202 , and the first shape corresponds to the shape of the second hook 304 on the top of the blanking plate 3 .

[0037] Specifically, a baffle 303 is fixedly connected to the bottom of the blanking plate 3 and extends above the chain plate of the chain conveyor 1 to prevent materials from falling out of the chain conveyor 1.

[0038] Specifically, the back side of the blanking plate 3 is fixedly connected with a handle 8 .

[0039] Specifically, two sides of the blanking plate 3 are provided with avoidance grooves 301 for accommodating the rotating shaft 6 and the fixing plate 4 .

[0040] Specifically, the avoidance groove 301 is used to accommodate the rotating shaft 6 and the fixed plate 4 during installation, so that the rear half of the avoidance groove 301 is filled with the rotating shaft and the fixed plate 4, and the front half of the avoidance groove 301 is inserted into the shell of the front end of the support frame 2, so that the avoidance groove 301 will not leak materials and fall directly onto the chain conveyor 1.

[0041] When the present invention is in use, it is first necessary to install the blanking plate 3 between the support frame 2, hold the handle 8 of the blanking plate 3, align the second hook 304 at the top of the blanking plate 3 with the first hook 202 of the support frame 2, push the blanking plate 3 along the slot, accommodate the rotating shaft 6 and the fixing plate 4 into the avoidance groove 301, and then press down the fixing bolt 201, compress the reset spring 203 and screw the fixing bolt 201 at the same time to connect the fixing bolt 201 with the threaded hole 302, thereby completing the installation.

[0042] The material is poured in from the top of the blanking plate 3, and the material slides down along the rear wall of the blanking plate 3 and contacts the buffer plate 5. Since the buffer plate 5 is connected by a rotating shaft 6 at one end, the buffer plate 5 will be pressed down by the material due to gravity, and the spiral spring 601 inside the rotating shaft 6 is also compressed. At this time, the movable rod 7 at the bottom of the buffer plate 5 will move as the buffer plate 5 is pressed down, and the other end of the movable rod 7 extends to the upper end of the fixed plate 4. At the same time, the bending spring 701 is sleeved on the movable rod 7. Since one end of the bending spring 701 is connected to the bottom of the fixed plate 4 and the other end is fixedly connected to the bottom of the buffer plate 5, the bending spring 701 will also be compressed when the buffer plate 5 is pressed down. The restoring force generated by the compression of the bending spring 701 provides the buffer plate 5 with a force in the opposite direction of pressing down, thereby reducing the impact force of the material pressing down and preventing damage to the chain conveyor 1. The gap that is then opened allows the material to continue to slide onto the chain.

[0043] After buffering is completed, the spiral spring 601 of the buffer plate 5 inside the rotating shaft 6 is released, thereby driving the buffer plate 5 to reset, and the bending spring 701 under the buffer plate 5 also assists the spiral spring 601 to quickly reset.

[0044] The remaining undescribed parts of the present invention are the same as the prior art, or are well-known technologies or can be implemented by using the prior art, and will not be described in detail here.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
