[0002] The feeder plays a crucial role in the operation of the mill, responsible for uniformly and stably conveying materials into the mill for grinding. Existing mill feeders have several problems in practical use: 1) The feeder cover is usually fixed to the cone, making the conical feed hopper prone to abrasion under prolonged material impact. Leaks are difficult to locate from the outside of the hopper, and due to the rubber lining inside the hopper, existing feed hopper structures can only be repaired by welding from the outside, leaving internal damage areas unlined. When cleaning, maintenance, and repair of the feeder's interior are required, the operating space is limited, disassembly is difficult, and significant manpower and time costs are incurred, severely impacting equipment maintenance efficiency and production progress; 2) Existing rubber lining methods only line the inner side of the cone, failing to effectively mitigate the impact of materials on weak welded points; 3) The currently assembled support frame is quite heavy, increasing the overall weight of the feeding device and placing additional load on the mill's operation, leading to increased energy consumption. Furthermore, the heavy support frame increases operational difficulty during equipment installation and handling; 4) The channel steel used in existing support frames is difficult to position and complex to process. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a conical mill feeder device with a detachable feeder cover to reduce material impact and improve maintenance efficiency, in order to address the deficiencies of the existing technology.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-8 As shown, this utility model provides a conical mill feeder device with a detachable feeder cover, including a conical feeder body 1, a feeder cover 2, a connecting bolt assembly 3, a conical feed hopper 4, and a support frame 6. The conical feeder body 1 is in the shape of an inverted frustum cone, with a square installation opening at the top. The feeder cover 2 is installed on the installation opening and is connected to the conical feeder body 1 by the connecting bolt assembly 3. The conical feeder body 1 has a feed inlet on its side and a discharge outlet at its bottom. The feeder cover 2 has a feed port, through which the material enters the feed hopper. After the material enters the conical feed hopper 4 through the feeder cover 2, the material is evenly distributed in the conical feeder. With the rotation or vibration of the feeder, the material is evenly pushed to the mill feed inlet.

[0025] The conical feed hopper 4 is lined with rubber inside and on the flange mounting surface to improve the wear resistance of the conical feeder body, reduce the impact of materials on weak weld points, and extend its service life.

[0026] The feed inlet on the side of the conical feeder body 1 is connected to the external material conveying pipeline, and the discharge port at the bottom is equipped with a feed bend 5, which is connected to the feed channel of the mill.

[0027] The feeder cover 2 is a welded component, formed by welding flanges and steel pipes. It includes flange 21, steel pipe 22, cover plate 23, flange 24, and steel pipe 25. One side of the cover plate 23 has steel pipe 22, with flange 21 welded to its top. Two steel pipes 25 are welded side-by-side to the other side of the cover plate 23, with flange 24 welded to their tops. The cover plate 23 has mounting holes around its circumference for connection with the conical feeder body 1 via bolt assembly 3. For maintenance or repair, the feeder cover 2 can be easily removed by simply unscrewing the bolts, greatly increasing the operating space and facilitating the inspection and replacement of various internal components.

[0028] The feeder cover 2 is lined with 4mm of high-quality wear-resistant rubber on the inner wall of the cover plate and flange, which fits tightly with the edge of the installation opening to form a sealing structure, effectively preventing material leakage and avoiding material waste. It also improves the working environment and protects the health of operators.

[0029] The support frame 6 includes a steel plate 61, a steel pipe 62, a stiffener 63, a steel plate 64, and a stiffener 65. The steel pipe 62 is vertically welded to the steel plate 64, and the steel plate 61 is welded to the top of the steel pipe 62.

[0030] A reinforcing rib 65 is welded between steel plate 61 and steel pipe 62; a reinforcing rib 63 is welded between steel plate 64 and steel pipe 62.

[0031] The conical feeder body 1 and the feed bend 5 are fixed on the steel plate 61 of the support frame 6.

[0032] The support frame 6 has been optimized and adopts a reasonable structural form, replacing channel steel with steel pipe for easier processing and positioning. While ensuring structural strength, smaller steel pipes are selected to reduce unnecessary material usage, reduce weight, lower the operating load of the mill, and achieve energy saving.

[0033] The connecting bolt assembly 3 includes multiple bolts, nuts, and washers, which are evenly distributed on the edge of the removable feeder cover. When disassembling, simply unscrew the locking bolts to separate them from the removable feeder cover, and the feeder cover can be easily removed.

[0034] The installation process of this utility model is as follows:

[0035] First, line the inside of the cone and the flange mounting surface with abrasion-resistant rubber, ensuring a uniform lining thickness. Then, line the bottom cover plate of the removable feeder cover with rubber, ensuring a tight fit against the edge of the mounting opening.

[0036] Next, the detachable conical feeder cover is secured to the mounting opening at the top of the conical feeder body using bolt assemblies. A 4mm wear-resistant rubber lining ensures a tight fit between the cover and the edge of the conical opening, effectively preventing material leakage and waste. Tighten the bolt assembly to complete the connection between the detachable feeder cover and the conical feeder body. During use, when cleaning, maintenance, or replacement of parts is required inside the conical feeder, unscrew the bolt assembly to separate it from the detachable feeder cover, allowing access to the inside of the conical feeder. The material is evenly distributed within the conical feeder, and with the rotation or vibration of the feeder, it is uniformly pushed to the mill inlet for the next stage of processing.

[0037] This invention utilizes a detachable feeder cover, making disassembly and installation simple and quick without the need for complex tools. This significantly shortens equipment maintenance time, improves repair efficiency, reduces equipment downtime, and helps ensure continuous production. The lightweight support frame reduces the operating load on the mill, decreases energy consumption, and meets energy conservation and environmental protection requirements. Replacing the channel steel with steel pipes facilitates positioning and processing. Wear-resistant rubber linings to each flange mounting surface cover all weld seams, mitigating the impact of material on weak weld points. This invention solves the aforementioned problems of existing feeders, enabling rapid disassembly of the feeder cover, reducing the impact of material on weak weld points, achieving lightweight support, and increasing processing speed.

[0038] The above-described embodiments of this utility model are merely illustrative examples and are not the only ones. All modifications within the scope of this utility model or equivalent to this utility model are encompassed by this utility model.
