A hand-tightening bolt 117 for tightening the rotating shaft is radially screwed onto the sleeve. By passing the extension through the slot and into the fixing groove, the rotating shaft is rotated to allow the rotating shaft to wind around the extension, thereby adjusting the screen. After the desired adjustment is achieved, the rotating shaft is tightened by the hand-tightening bolt to prevent the rotating shaft from rotating back. At the same time, the front and rear parts of the screen are attached to the front and rear side walls of the feed hopper.
[0029] In this embodiment, the dustproof cloth is placed around the outer perimeter of the screen mesh.
[0030] In this embodiment, a feed pipe 202 is provided on the top plate of the material handling box. The lower end of the discharge pipe is fitted onto the feed pipe and equipped with a quick-lock 203. A gate is also provided at the lower end of the discharge pipe to control the opening and closing of the discharge pipe. The dust suction pipe is also detachably connected to the dust outlet 204 on the top plate of the material handling box via a quick-lock, so that the dust suction pipe can be separated from the dust outlet after receiving materials, facilitating the movement of the material handling box. The dust suction pipe is connected to an external ventilation device.
[0031] In this embodiment, to prevent material from adhering to the inner wall of the receiving hopper, a pneumatic hammer 303 is installed on the side wall of the receiving hopper. The discharge pipe can be a cloth bag pipe for easy movement.
[0032] In this embodiment, the material box is mounted within the movable frame 220 via an elastic element 223, and casters 221 are provided at the bottom of the movable frame. One pair of casters may be motor wheels to facilitate the movement of the material box and reduce the need for manual pushing.
[0033] In this embodiment, a discharge port 205 is provided in the middle of the bottom plate of the material box. The discharge hopper includes an inner tube 211 fixed to the lower side of the discharge port. A discharge gate 212 driven by a horizontal electric cylinder or a pneumatic cylinder is provided on the inner tube. A funnel-shaped outer tube 213 is sleeved on the inner tube. A drive mechanism for driving the outer tube to rise and fall is provided on the bottom plate of the material box, thereby realizing the extension and retraction of the discharge hopper.
[0034] In this embodiment, the driving mechanism includes a fixing plate 214 fixed to the front and rear sides of the outer tube, and a vertical electric cylinder 215 with its upper end connected to the bottom plate of the material handling box is mounted on the fixing plate. Thus, when the material handling box moves to the discharge port, the outer tube extends and connects with the discharge port.
[0035] In this embodiment, to prevent the outer tube from being scratched, a rubber layer 216 or a buffer layer is provided on the outer side wall of the outer tube, and the rubber layer and the buffer layer are food grade.
[0036] In this embodiment, to facilitate the smoother unloading of materials from the material handling box, inclined plates 217 are installed around the unloading port inside the material handling box. The upper end of the inclined plate is connected to the side wall of the material handling box, and the lower end is connected to the edge of the unloading port. Simultaneously, a vibration motor 222 can be installed on the bottom surface of the material handling box to further facilitate material discharge from the unloading port.
[0037] In this embodiment, a matching anti-detachment structure is provided between the outer tube and the inner tube; specifically, an annular outer flange 218 is provided on the lower outer wall of the inner tube, and an annular inner flange 219 is provided on the upper inner wall of the outer tube, so that after the outer tube moves into place, the annular inner flange is fastened to the annular outer flange.
[0038] In this embodiment, the top plate of the material handling box can be a transparent plate to allow observation of the material receiving and unloading process inside the box. In another embodiment, a weighing sensor connected to the moving frame can be installed between the bottom of the material handling box and the elastic element. The weighing sensor is connected to a display located on the side wall of the moving frame via a microcontroller to measure the weight change of the material handling box, so as to control the opening and closing of the unloading gate or the discharge pipe based on the weight.
[0039] In this embodiment, the movable frame may also be equipped with handrails. A portable power source (battery) for powering the various components may also be provided on the movable frame.
[0040] After being screened by the screening mechanism, the input material is fed into the conveying hopper through the discharge pipe. During the discharge process, the dust suction pipe is activated to remove the generated dust. Once the material in the conveying hopper reaches the required displacement, the discharge pipe and feed pipe are disconnected, and a cover plate is installed on the feed pipe; simultaneously, the dust suction pipe is separated from the dust outlet. After the conveying hopper is moved to the designated unloading position, the discharge hopper is extended and connected to the unloading port. After unloading is completed, the unloading gate is closed, and the conveying hopper is then moved back below the screening mechanism.
[0041] After a period of use, the dust adhering to the dustproof cloth can be knocked off by tapping it.
