[0029] participate Figure 1 This utility model provides an anti-clogging feeding device, including a hopper 3, a feeding port 11 at the bottom of the hopper 3, and an auxiliary feeding device on the hopper 3.

[0030] The auxiliary feeding device includes a drive unit 1, a transmission component and a scraping component. The output end of the drive unit 1 is connected to one end of the transmission component, and the other end of the transmission component is connected to the scraping component. The scraping component is located above the feeding port 11 and is used to scrape the accumulated material into the feeding port 11.

[0031] The anti-clogging feeding device provided by this utility model is equipped with an auxiliary feeding device in the hopper 3. The auxiliary feeding device includes a driving device 1, a transmission component and a scraping component. During the feeding process, the driving device 1 provides a driving force, which is transmitted to the scraping component through the transmission component. The scraping component scrapes off the viscous and poorly flowing material on the hopper wall, thereby improving the feeding efficiency.

[0032] Optionally, the scraping assembly includes a support rod 6 and multiple scrapers 5. The support rod 6 is parallel to the conical part of the hopper 3. Multiple scrapers 5 are provided on the support rod 6. The scrapers 5 are inclined downwards and the bottom end of the scrapers 5 is parallel to the inner wall of the cone of the hopper 3. The support rod 6 is connected to the transmission assembly.

[0033] Specifically, the scraping assembly includes a support rod 6 and multiple scrapers 5. The support rod 6 is arranged parallel to the conical portion of the hopper 3, as shown below. Figure 1 As shown, the conical section of the hopper 3 is parallel to the support rod 6. Multiple scrapers 5 are spaced apart on the support rod 6, with one end welded to the support rod 6 and the other end parallel to the inner wall of the cone-shaped hopper 3. To improve the working efficiency of the scrapers 5, and considering the structure of the inner wall of the cone-shaped hopper 3, the scrapers 5 can be tilted downwards. During operation, each scraper 5 moves in a circular motion around the transmission assembly under the drive of the support rod 6, scraping off the material adhering to the inner wall of the hopper 3. The scrapers 5 are not designed to directly contact the inner wall of the cone-shaped hopper 3 to prevent damage to the inner wall under high-speed rotation; therefore, a certain distance is sufficient, generally 1-2 cm.

[0034] Optionally, the transmission assembly includes a stirring shaft 12, which is coaxially arranged with the hopper 3. The drive device 1 is connected to the bottom end of the stirring shaft 12, and the bottom end of the stirring shaft 12 is rotatably mounted on the discharge port 11.

[0035] like Figure 4 As shown, there are two support rods 6, which are symmetrically arranged about the stirring shaft 12. Each support rod 6 is provided with multiple scrapers 5 at intervals, and the scrapers 5 on the two support rods 6 are staggered so that all scrapers 5 can scrape off all the material on the cone of the hopper 3 during the operation.

[0036] Optionally, the bottom ends of the two support rods 6 are directly connected to the stirring shaft 12, and the top ends of the support rods 6 are connected to the stirring shaft 12 through a connecting rod 4 arranged radially.

[0037] Optionally, the bottom end of the scraper 5 is spaced 10-20mm from the cone of the hopper 3, and the scraper 5 and the support rod 6 are set at a 45° angle.

[0038] Specifically, the connecting rod 4 and the support rod 6 are both welded to the stirring shaft 12. The connecting rod 4 and the support rod 6 are both round steel pipes. The scraper 5 is welded to the support rod 6, and the welding angle is arranged at 45 degrees. The bottom of the support rod 6 and the scraper 5 are parallel to the cone of the hopper 3. The gap between the bottom of the scraper 5 and the cone of the hopper 3 is generally 10-20mm.

[0039] Optionally, a support plate 10 is provided radially in the discharge port 11, a bearing box 9 is provided on the support plate 10, a bearing 8 is provided inside the bearing box 9, and the bottom end of the stirring shaft 12 is connected to the bearing.

[0040] like Figure 2 , Figure 5 As shown, a support plate 10 is provided in the diameter direction of the discharge port 11, and the bearing box 9 is welded to the support plate 10. The support plate 10 and the bearing box 9 are configured to fix the bottom end of the stirring shaft 12.

[0041] Optionally, a frame 2 is provided on the top of the hopper 3, and a drive unit 1 is located on the frame 2. The drive unit 1 includes a motor and a reducer. The output end of the motor is connected to the reducer, and the reducer is connected to the top end of the stirring shaft 12.

[0042] like Figure 3 As shown, a frame 2 is welded to the top of the hopper 3 to secure the drive unit 1. The motor and reducer of the drive unit 1 are fixed to the frame 2 with bolts. The motor provides the driving force, which is transmitted to the stirring shaft 12 through the reducer.

[0043] Optionally, a conical guard plate 7 is provided at the bottom end of the stirring shaft 12, and there is a gap of 0.4-0.7mm between the conical guard plate 7 and the bearing housing 9.

[0044] like Figure 2 As shown, in order to prevent material from entering the bearing housing 9, a conical guard plate 7 is welded on the stirring shaft 12, and there is a gap of 0.4-0.7mm between the conical guard plate 7 and the bearing housing 9.

[0045] The working principle of the device provided by this utility model is as follows: When materials with poor flowability come down from the feed inlet, they accumulate in the cone position of the hopper. Only a small amount of material flows out from the discharge port. When the reducer and motor are turned on, the stirring shaft, connecting rod, support rod and scraper start to rotate. The material in the cone is scraped by the scraper to the discharge port and flows out from the discharge port.

[0046] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
