[0002] During the production process of silicon carbide fine powder, a loader is required to add the silicon carbide raw material to the crusher for crushing. The crushed silicon carbide particles are then added to the screening machine, particles smaller than 4mm are selected, and then the silicon carbide particles larger than 4mm are added to the crusher for re-crushing. The qualified silicon carbide particles screened out are then added to the ball mill and ground into 50-200μm fine powder. In the above production process, the process of adding the silicon carbide raw material to the crusher and the process of adding the silicon carbide particles to the ball mill both require the use of a loader for transportation. However, in the actual production process, due to the process of the loader's transportation, it is necessary to first load the material and then tilt the loader's bucket and pour it into the corresponding container. Due to the insufficient aperture of the container mouth and air flow problems, the raw materials will overflow to the outside during this process, resulting in waste. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will describe in detail the embodiments of the technical solution of the present application in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application.

[0020] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of a non-buffered loading and unloading device for producing silicon carbide fine powder provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the cross-sectional structure of the receiving hopper provided in an embodiment of the present application. Figure 3Schematic diagram of the local structure of the protective cylinder provided in the embodiment of the present application. The buffer-free loading and unloading equipment 100 used for the production of silicon carbide fine powder includes a loader body 110. The loader body 110 can be purchased on the market. It is used to drive the receiving hopper 130 to move, so as to facilitate the completion of operations such as receiving and unloading after the equipment is moved to a suitable site. The loader body 110 is connected to the receiving hopper 130 through a driving device 120. The driving device 120 is used to drive the receiving hopper 130 to flip and receive materials and to drive the receiving hopper 130 to lift and fall. The driving device 120 is a prior art. When it is necessary to transport silicon carbide raw materials, it can drive the receiving hopper 130 to flip a certain angle and then perform a shoveling operation, thereby shoveling up the silicon carbide raw materials on the ground. When it is necessary to transport silicon carbide powder, the driving device 120 adjusts the receiving hopper 130 to a suitable angle through cooperation with the loader body 110 and then sends it to the bottom of the crusher for loading. The bottom of the hopper 130 is connected to a discharge pipe 140. The discharge pipe 140 and the hopper 130 may be integrally formed. It is conceivable that, to facilitate discharge, the connection between the hopper 130 and the discharge pipe 140 may be formed through a conical chamber. A closing valve is provided within the inner cavity of the discharge pipe 140. When the closing valve is closed, the material in the hopper 130 cannot fall into the rubber hose 150. Conversely, the material in the hopper 130 can be transported to the rubber hose 150 through the discharge pipe 140. The bottom of the discharge pipe 140 is fixedly connected to the rubber hose 150. The rubber hose 150 has a certain degree of elasticity and can bend. Two symmetrically positioned hinge shafts 141 are fixed to the outer periphery of the discharge tube 140. A protective tube 160 is attached to the outer periphery of the rubber hose 150. This protects the rubber hose 150 from wear and tear during movement with the loader body 110. Two symmetrical lugs 161 are symmetrically positioned at the top of the protective tube 160, each hinged to one of the hinge shafts 141. The protective tube 160 is rotatably connected to the discharge tube 140 via the hinge shafts 141. Therefore, when the loader body 110 drives the hopper 130 to shovel material, the protective tube 160 will adaptively rotate along the hinge shafts 141 under the action of external forces, without affecting the loading process. The bottom end of the protective cylinder 160 expands outward to form an annular base 162, and the annular base 162 is sheathed on the outer periphery of the protective cylinder 160. At least one counterweight block 170 is detachably provided on the annular base 162. By providing the counterweight block 170, when the loader body 110 drives the receiving hopper 130 to complete the loading operation, the protective cylinder 160 can naturally move vertically downward under the action of gravity, thereby facilitating the discharge of the material in the receiving hopper 130 into the corresponding container 200.

[0021] As can be seen from the above, in the embodiment of the present application, by providing a discharge pipe 140 and a rubber hose 150 at the bottom of the receiving hopper 130 to transfer materials, the material in the receiving hopper 130 will pass through the discharge pipe 140 and the rubber hose 150 in sequence and enter the corresponding container 200 during the discharge process of the device, thereby avoiding the phenomenon of material splashing onto the periphery of the container 200 during the discharge process in the prior art. On the other hand, in the embodiment of the present application, the protective tube 160 is provided to protect the rubber hose 150, preventing the rubber hose 150 from leaking due to wear. Since the protective tube 160 is hinged to the bottom of the discharge pipe 140 via the hinge shaft 141, when the drive device 120 drives the receiving hopper 130 to rotate and shovel materials, the protective tube 160 can rotate in the opposite direction after receiving the force from the ground, without affecting the shoveling process. The provision of the counterweight ring allows the protective tube 160 of the device to remain vertically downward in its natural state, thereby facilitating the subsequent discharge operation.

[0022] In some embodiments, a counterweight ring is included, which is formed by a plurality of counterweight blocks 170, and the counterweight ring is annular. In the embodiment of the present application, a counterweight ring can be composed of a plurality of counterweight blocks 170, so that in the device, each counterweight block 170 is evenly arranged on the outer periphery of the protective tube 160.

[0023] In some embodiments, threaded holes are provided on the plurality of counterweights 170 and the annular base 162, and the counterweights 170 are screwed to the annular base 162 via screws. In the embodiment of the present application, through the above arrangement, each counterweight 170 can be conveniently connected to the annular base 162 via screws, and the process of removal and replacement is very convenient.

[0024] In some embodiments, please refer to Figure 4 , Figure 4 Schematic diagram of the local structure of the connection between the protective tube and the corresponding container provided in the embodiment of the present application. The annular base 162 is made of iron material, the counterweight ring is a natural magnet, and a plurality of receiving grooves 162a are provided on the top of the annular base 162, and the counterweight blocks 170 are respectively placed in the receiving grooves 162a. In the embodiment of the present application, a corresponding magnetic ring 220 can be set on the top of the feed port 210 of the container 200 for receiving raw materials, so that when the hopper 130 of the device is close to the corresponding container 200, under the action of magnetism, the counterweight ring will adaptively move close to the feed port 210, making it convenient for the driver to find the position of the discharge port (the driver usually sits in the loader body 110 and needs to look up when observing the position of the feed port 210 of the above-mentioned container 200, and there is a blind spot in the process of looking up, and it is impossible to accurately judge the position of the feed port 210). Then, the driver can align the counterweight ring with the above-mentioned magnetic ring 220 and then discharge the material.

[0025] In some embodiments, the length of the rubber hose 150 is shorter than the length of the protective tube 160 so that the end of the rubber hose 150 is located inside the inner cavity of the protective tube 160. In this embodiment of the present application, the above arrangement prevents the rubber hose 150 from exceeding the end of the protective tube 160 and causing unnecessary wear.

[0026] In some embodiments, the bottom end of the feed tube 140 is provided with an annular connecting groove 142, the top end of the rubber hose 150 extends upward and is fixed in the connecting groove 142, and the feed tube 140 is provided with a plurality of positioning pins 143, which sequentially pass through the feed tube 140, the connecting groove 142, and the rubber hose 150. In the embodiment of the present application, the above arrangement can stably connect the rubber hose 150 to the bottom of the feed tube 140.
