[0026] The first embodiment of this utility model is as follows:

[0027] A feeding device for resin-coated urea production includes a base 6 with casters 7 installed at the bottom for easy movement. A feeding assembly is inclinedly arranged on the upper part of the base 6. The feeding assembly includes a sleeve 11 with a clamp 9 installed in the middle of the sleeve 11. A support rod 8 is installed on the base 6 and connected to the clamp 9 to support the sleeve 11. A screw 10 is rotatably arranged inside the sleeve 11, with the edge of the screw 10 close to the inner edge of the sleeve 11. When it rotates, it can transport the raw material from bottom to top. The lower end of the sleeve 11 has an upward-facing feeding port 3, which is connected to a feeding box 4. The upper end of the sleeve 11 has a downward-facing discharge port 12. A bearing is installed at the upper end of the sleeve 11 and is connected to the screw 10, which serves both as a seal and a connection, allowing the screw 10 to rotate smoothly.

[0028] The base 6 is equipped with a motor 2 and a reducer 1 connected to each other. The lower end of the sleeve 11 is equipped with a sealing plate with a through hole in the middle. A bearing is installed at the through hole. The drive shaft 5 of the reducer 1 extends through the sealing plate into the sleeve 11 and is connected to the screw 10 through the bearing. On the one hand, it can play a sealing role to prevent the raw material from leaking from the lower end of the sleeve 11. On the other hand, it can ensure the normal operation of the screw 10. The motor 2 outputs power, which is transmitted to the screw 10 through the reducer 1, causing the screw 10 to rotate and transmit the raw material to the discharge port 12 at the upper end of the sleeve.

[0029] A feeding component is fixedly installed at the lower end of the feeding component. Inside the feeding component is a filter material component for filtering and dispersing raw materials. The feeding component includes a feeding box 4 connected to the feeding port 3. The feeding box 4 has a two-section structure, with the lower section being a rectangular cone structure and the upper section being a rectangular cylindrical structure. The filter material component is located in the upper section of the feeding box 4. The rectangular cone structure of the lower section ensures that all raw materials are concentrated and conveyed downwards.

[0030] The bulk material filtration assembly includes a filter plate, a dispersing plate 43, and a vibrating plate 44 arranged sequentially from top to bottom. The filter plate can filter out large impurities and clumps of raw materials that cannot be broken down, and then sweep them out. The dispersing plate 43 is used to break down the raw materials that can be broken down, and the vibrating plate 44 is used to further screen the raw materials. Vibration ensures that the raw materials are dispersed, improves the dispersion effect, and ensures that the raw materials will not cause blockage due to clumping after entering the sleeve 11 through the feed port 3.

[0031] The filter plate includes an upper filter plate 41 fixedly connected to the feeding box 4 and a lower filter plate 42 slidably connected to the feeding box 4. The feeding box 4 is provided with a slide and an opening near the filter plate. The lower filter plate 42 is connected to the feeding box 4 through the slide. One end of the lower filter plate 42 extends out from the opening. The upper filter plate 41 and the lower filter plate 42 are respectively provided with upper filter holes 48 and lower filter holes 49 of the same diameter. When the lower filter plate 42 slides to the innermost position, the upper filter holes 48 and lower filter holes 49 overlap. At the same time, the upper section of the feeding box 4 is also provided with a foldable side plate. The lower end of the side plate is flush with the upper surface of the filter plate and is connected to the feeding box 4 by a latch.

[0032] The dispersion plate 43 is provided with a number of dispersion holes. In this application, it can be made by welding steel bars in a crisscross pattern. When the raw material falls onto the dispersion plate 43, it will automatically disperse and fall towards the vibrating plate 44 under the action of gravity and impact.

[0033] The vibrating plate 44 is provided with several slots and holes, and a vibrator 45 is fixedly installed at the lower part of the vibrating plate 44; a cavity is provided inside the feeding box 4, and a spring 47 is provided at the lower part of the cavity. The upper end of the spring 47 is connected to the edge of the vibrating plate 44. The vibrating plate 44 is made to vibrate by the vibrator 45, so that the raw materials falling on the vibrating plate 44 can be further dispersed and the dispersion effect is improved.

[0034] Meanwhile, the pore size gradually decreases from the filter plate, the dispersion plate 43 to the vibration plate 44.

[0035] When in use, the raw materials are put into the feeding box 4. Impurities in the raw materials will be filtered out by the filter plate, and then fall onto the dispersing plate 43 and the vibrating plate 44 in sequence. After being fully dispersed, they enter the sleeve 11 and are conveyed upward by the screw 10 and discharged from the outlet 12.

[0036] Then open the latch, fold the flap 46 downwards, and push the lower filter plate 42 so that the upper filter hole 48 and the lower filter hole 49 do not overlap, thus sealing the filter plate. Then use a broom to remove the impurities on the filter plate from the flap 46. Pull the lower filter plate 42 to make the upper filter hole 48 and the lower filter hole 49 overlap, and you can feed material again.

[0037] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.
