When the device is used, the conveying assembly 2 arranged in the support frame 1 can be used to convey materials, and the intercepting mechanism 3 arranged in front of the support frame 1 can intercept large block materials that may appear in front of the transfer point, preventing the large block materials from jamming the equipment when passing through the transfer point, thereby ensuring the normal operation of the device, increasing the practicality of the device, and being conducive to the promotion of the equipment.

[0026] The intercepting mechanism 3 comprises an intercepting rod 31 fixedly installed near the transfer point of the support frame 1, a pushing frame 33 slidably installed in the support frame 1 and located at one side of the intercepting rod 31 and capable of resisting the bulk material, a transmission sprocket set 32 arranged in the support frame 1 and used for driving the pushing frame 33 to move, and a pushing assembly 34 arranged in the pushing frame 33.

[0028] Embodiment two

[0029] With reference to Figures 1-4The embodiment is basically same as the embodiment one, and is more optimized in that the upper portion of the discharging box 35 is provided with a screen 36, and the lower portion of the screen 36 is provided with a vibration assembly 37, and the lower portion of the discharging box 35 is rotatably provided with a discharging door 38. The large material pushed out of the support frame 1 will directly fall on the screen 36. When the pushing rod 341 pushes the large material, part of the normal material will be moved together, so part of the material will fall on the screen 36 together. Because the particle size of the large material is larger than that of the normal material, the large material will be left on the screen 36, and the small material will fall into the discharging box 35 through the screen 36, so as to automatically separate the large material from the small material, and the intelligence of the equipment is embodied.

After the impact ends, the vibration spring 372 will release the impact kinetic energy through constant shaking, so as to cause the screen 36 to constantly shake, and accelerate the separation of the normal material from the large material on the screen 36.

[0031] The inner cavity of the discharging box 35 is provided with an inclined surface at the bottom. When the small material passes through the screen 36, it will slide along the inclined bottom of the discharging box 35 to the lowest end of the inner cavity of the discharging box 35 under the action of gravity, so as to reduce the difficulty of collecting the small material, and facilitate the collection of the material by the workers.

[0032] The conveying assembly 2 comprises a conveying wheel 21 rotatably installed in the support frame 1, a conveying chain 22 externally sleeved with the conveying wheel 21, a scraper 23 fixedly installed on one side of the conveying chain 22 for conveying the material.

[0033] The support frame 1 is provided with a driving assembly 4 for controlling the operation of the conveying assembly 2 and the intercepting mechanism 3, the driving assembly 4 comprises a driving motor 41 fixedly installed on one side of the support frame 1, a driving sprocket set 42 is in transmission connection with the output end of the driving motor 41, and the driving motor 41 is in transmission connection with the transmission sprocket set 32 and the conveying wheel 21 through the driving sprocket set 42.

In addition, through mechanical transmission, the driving sprocket set 42 drives the transmission sprocket set 32 to move, thereby driving the pushing frame 33 to move, and achieving the function of pushing out the large materials.

[0040] Further, the vibration assembly 37 includes a vibration frame 371 fixedly installed in the lower discharge box 35, a vibration rod 373 is slidably installed in the vibration frame 371, the upper portion of the vibration rod 373 is fixedly connected with the screen 36, and a vibration spring 372 is fixedly installed at the lower portion of the vibration rod 373 and is fixedly connected with the vibration frame 371 at one end, through the setting of the vibration spring 372, when the large material falls on the screen, the vibration spring 372 can absorb the impact force at the first time, and continuously shakes after the impact is over, and the impact kinetic energy is released, so as to cause the screen to vibrate, and accelerate the separation of the normal material and the large material thereon.

[0041] Further, the inner cavity bottom of the lower discharge box 35 is provided as an inclined surface.

[0042] Further, the conveying assembly 2 includes a conveying wheel 21 rotatably installed in the support frame 1, the conveying wheel 21 is externally sleeved with a conveying chain 22, and the conveying chain 22 is fixedly installed with a scraper 23 for conveying material on one side.

[0043] Further, the support frame 1 is provided with a driving assembly 4 for controlling the operation of the conveying assembly 2 and the intercepting mechanism 3, the driving assembly 4 includes a driving motor 41 fixedly installed on one side of the support frame 1, and a driving sprocket set 42 is drivingly connected with the output end of the driving motor 41, and the driving motor 41 is drivingly connected with the transmission sprocket set 32 and the conveying wheel 21 through the driving sprocket set 42.

[0044] Working principle:

[0045] When the device is in use, the driving motor 41 can be started to drive the driving sprocket set 42 to rotate, and the driving sprocket set 42 drives the transmission sprocket set 32 to rotate through the transmission connection, and then drives the pushing frame 33 to make endless circular motion in front of the transfer point, so as to cooperate with the pushing assembly 34 to push the large block material intercepted by the intercepting rod 31 out of the support frame 1, thereby achieving the effect of intercepting large block material and improving the practicability of the device. Since the pushing rod 341 is slidingly installed in the pushing frame 33, when the pushing frame 33 makes endless circular motion in the support frame 1, the pushing rod 341 can be driven to move synchronously in the support frame 1. When the pushing rod 341 moves at the lower part of the support frame 1, the pushing gear 343 rotatingly installed in the pushing frame 33 starts to rotate through the mutual meshing with the pushing rack 344, and drives the pushing lead screw 342 coaxially fixed thereto to rotate in the rotating process, and then drives the pushing rod 341 threadedly connected thereto to separate to both sides. Since one side of the pushing rod 341 is in contact with the large block material, the large block material is driven to move to the edge of the support frame 1, and then is pushed to the front of the closing plate 346. At this time, under the action of the pushing rod 341, the large block material extrudes the closing plate 346 to open, so as to push the large block material into the discharge box 35. Since the closing plate 346 is elastically hinged to the support frame 1, when the large block material passes through the closing plate 346, the closing plate 346 is automatically closed to prevent other normal materials from falling from the support frame 1, thereby reducing the waste of resources. Since the pushing rod 341 pushes the large block material, part of the normal materials will move together, so part of the materials will fall on the screen 36. Since the particle size of the large block material is larger than that of the normal material, the large block material will be left on the screen 36, and the small block material will pass through the screen 36 and fall into the discharge box 35, thereby automatically separating the large block material from the small block material, which reflects the intelligence of the equipment. When the large block material falls on the screen 36, the vibration spring 372 is compressed by the vibration rod 373, and after the impact is over, the vibration spring 372 releases the impact kinetic energy through constant shaking, thereby causing the screen 36 to shake constantly and accelerating the separation of the normal material and the large block material. In addition, the inner cavity bottom of the discharge box 35 is provided with an inclined surface. When the small block material passes through the screen 36, it will slide to the lowest end of the inner cavity of the discharge box 35 along the inclined bottom of the discharge box 35 under the action of gravity, thereby reducing the difficulty of collecting small block materials and facilitating the collection of materials by workers. When the driving sprocket set 42 rotates, the conveying wheel 21 rotates, thereby driving the conveying sprocket 22 to move, and then driving the scraper 23 fixedly installed on the conveying connection 22 to move, thereby achieving the effect of moving the materials in the support frame 1, thereby realizing the transportation of the materials. The present application realizes the function of intercepting large block materials in front of the loading point through the setting of the intercepting mechanism, thereby avoiding the problem that the large block materials will jam the equipment when passing through the transfer point, thereby ensuring the normal operation of the device, increasing the practicability of the device, being conducive to the promotion of the equipment, and utilizing the setting of the filter screen,The material falling on the filter screen is automatically separated according to the particle size, the large block material is left on the screen, and the small block material is left under the discharge box, the separation of the large block material and the small block material is realized, the intelligence of the equipment is embodied, the impact force is absorbed by the vibration spring in the first time when the large block material falls on the screen, and the impact energy received is continuously shaken after the impact is over, the impact energy is released, the screen vibration is caused, and the separation of the normal material and the large block material is accelerated, the function of intercepting the large block material before the loading point is realized through the setting of the intercepting mechanism, the problem that the equipment is stuck when the large block material passes through the transfer point is avoided, the normal operation of the device is ensured, the practicability of the device is increased, the equipment is conducive to popularization, the material falling on the filter screen is automatically separated according to the particle size, the large block material is left on the screen, and the small block material is left under the discharge box, the separation of the large block material and the small block material is realized, the intelligence of the equipment is embodied, the impact force is absorbed by the vibration spring in the first time when the large block material falls on the screen, and the impact energy received is continuously shaken after the impact is over, the impact energy is released, the screen vibration is caused, and the separation of the normal material and the large block material is accelerated.
