[0020] Embodiment 1

[0021] As Figure 1 and 2 The solid bunker anti-bridging discharging device of the present utility model comprises a main shaft 14, the lower end of the main shaft is connected with the output shaft of a motor 6 through a shaft coupling 8, and the motor drives the main shaft to rotate. The upper part of the main shaft is connected with a scattering blade 2, and the scattering blade is fixedly connected or detachably connected with the main shaft. The scattering blade is in the shape of a stick or a rod, the number of the scattering blades is greater than or equal to one, and the lengths of the scattering blades are different. The scattering blades mainly play a role of scattering materials. Preferably, the scattering blades are connected perpendicularly with the main shaft, and the scattering blades are arranged in layers from top to bottom on the main shaft. The scattering blades are evenly distributed on the main shaft, and preferably, the scattering blades are arranged in layers and staggered. This arrangement mode makes the scattering blades have a larger contact range with the materials. A scraping tooth 1 is arranged at the end of the scattering blade. The scraping tooth has a larger surface area, increases the contact area with the materials, and improves the overall material scattering efficiency. The scraping tooth can be in various shapes, such as a flat plate, a curved blade, or a bamboo raft. Figure 1 As shown in the figure, the scraping tooth is composed of a support rod and a short rod. The support rod and the short rod are arranged perpendicularly. The support rod can be one or two, and the short rod can be several. The short rods are evenly connected with the support rod. The short rods and the support rod are in the same plane, and the support rod is connected with the end of the scattering blade. Preferably, the scraping tooth and the scattering blade are at a certain angle, so that when the solid bunker is installed, the scraping tooth can better approach the wall of the solid bunker, and play a better role in scattering materials and preventing bridging.

[0022] Furthermore, a forward spiral blade 4 and a discharge mechanism are connected to the main shaft. The forward spiral blade is located below the dispersing blade, and the discharge mechanism is located below the forward spiral blade. The discharge mechanism includes a main shaft box 3, which is a tubular structure with an open top and a bottom plate 15. The main shaft box contains a reverse spiral blade 11, a gearbox 13, and a discharge spiral rod 12. A discharge pipe 7 is provided on the side wall of the main shaft box, and the discharge pipe communicates with the main shaft box. The main shaft passes through the main shaft box and is located at the central axis of the main shaft box. The reverse spiral blade is mounted on the main shaft. The discharge spiral rod is rod-shaped, with a spiral blade fixed at one end and the other end perpendicularly meshing with the main shaft through a gear mechanism. All or part of the spiral blade of the discharge spiral rod is located inside the discharge pipe. The gearbox is located below the reverse spiral blade and is a hollow box with the gear mechanism located inside. The function of the forward spiral blades is to convey materials. Driven by the main shaft, the forward spiral blades rotate and push the materials downwards towards the discharge pipe. The reverse spiral blades have the opposite spiral direction to the forward spiral blades. When the materials move to the reverse spiral blades, they stop descending due to the obstruction of the reverse spiral blades, preventing the materials from clogging and entering the gearbox 13.

[0023] Furthermore, the gear mechanism can be a worm gear structure, with the worm 9 mounted on the main shaft and the worm wheel 10 mounted at one end of the discharge screw. The worm wheel and worm mesh perpendicularly, and the rotation of the main shaft drives the discharge screw to rotate, pushing the material to the discharge port and improving the material discharge speed.

[0024] Furthermore, a flange or other connecting component 5 is provided at the opening of the spindle box for connection to the hopper.

[0025] Example 2

[0026] Figure 3 This is a schematic diagram of the installation of the solid material silo anti-bridging discharge device of this utility model. Figure 3 As shown, the opening of the spindle box is installed at the bottom of the solid silo via flanges and other connecting parts, with the spindle overlapping the central axis of the silo. By adjusting the length of the dispersing blades and the angle of the scraper teeth and dispersing blades, a very small distance is made between the scraper teeth and the side wall of the solid silo, making it easier to prevent material bridging.

[0027] When solid material needs to be discharged, motor 6 is turned on. The rotation of motor 6 drives the main shaft to rotate, which in turn drives the dispersing blades 2 to rotate. The dispersing blades 2 are arranged in a staggered pattern on the upper part of the main shaft, ensuring maximum contact area between the dispersing blades 2 and the material. When the dispersing blades 2 rotate, the scraper teeth 1 at their ends increase the contact area with the material, improving the overall material dispersing efficiency and avoiding material sticking to the wall or bridging. After being processed by the dispersing blades 2 in conjunction with the scraper teeth 1, the material becomes loose. Driven by the forward spiral blades 4 on the main shaft, the material moves downward into the discharge pipe. At the same time, the rotation of the reverse spiral blades 11 on the main shaft prevents the material from falling into the gearbox.

[0028] Simultaneously, the rotation of the main shaft drives the worm gear to rotate, which in turn drives the discharge screw to rotate, forcibly pushing the material in the discharge pipe out, thus completing the material discharge. The worm gear is driven by the worm of the main shaft, requiring no other power source, ensuring synchronous rotation while saving energy.

[0029] This invention effectively solves the problem of bridging, improves material discharge efficiency, has a simple structure, high adaptability, and can be widely used in the industry.

[0030] The above-described specific embodiments are merely particular examples of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical principles of this utility model shall fall within the patent protection scope of this utility model.
