[0002] During the operation of a ball mill, the feed chute is a key component for material conveying, and its performance directly affects the feeding efficiency and service life of the ball mill.
[0003] Existing ball mill feed chutes mostly adopt an integral horizontal rib structure, with the horizontal ribs fixedly connected to the chute body. When the horizontal ribs need to be replaced due to wear, the entire chute needs to be disassembled, which is cumbersome, time-consuming, and labor-intensive. When the material slides down in the chute, it directly impacts the bottom of the chute body, which can easily cause rapid wear of the chute body, shorten the replacement cycle of the chute, and increase equipment maintenance costs.
[0004] The horizontal ribs are fixedly connected to the trough. When the horizontal ribs need to be replaced due to wear, the entire chute needs to be disassembled. The disassembly and assembly process is cumbersome, time-consuming and labor-intensive. When the material slides down in the chute, it directly impacts the bottom of the trough, which can easily cause the trough to wear quickly, shorten the replacement cycle of the chute and increase the equipment maintenance cost. Utility Model Content
[0005] The purpose of this utility model is to provide a ball mill feed chute to solve the problems mentioned in the background art, such as the fixed connection between the horizontal rib and the chute body, the need to disassemble the entire chute when the horizontal rib needs to be replaced due to wear, the disassembly and assembly process is cumbersome, time-consuming and labor-intensive; when the material slides down in the chute, it directly impacts the bottom of the chute body, which can easily cause the chute body to wear quickly, shorten the replacement cycle of the chute, and increase the equipment maintenance cost.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a ball mill feed chute, comprising a chute body and a transverse rib structure, wherein the transverse rib structure is inserted into the inner side of the chute body, the chute body comprises a side plate and a liner plate, and the side plate is provided with an insertion hole; the transverse rib structure is provided with a connecting plate, and the inner side of the connecting plate is connected to a transverse rib, which is inserted into the inner side of the insertion hole.
[0007] Preferably, the side plate is provided in two sets, and one set of the side plate has threaded holes.
[0008] Preferably, the liner includes a drop plate, a slide plate, and connecting bolts.

[0010] Preferably, the insertion hole is located above the blanking plate, the horizontal rib is located above the blanking plate, and multiple sets of horizontal ribs are provided to form a stepped recessed area on the blanking plate.
[0011] Preferably, a handle is connected to the outside of the connecting plate, a positioning bolt is inserted into the connecting plate and inserted into the threaded hole, and a groove is provided at the bottom of the connecting plate, the groove corresponding to the connecting bolt.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. The ball mill feed chute has a transverse rib that is connected to the side plate through the insertion hole and fixed with the positioning bolt and threaded hole. When disassembling, only the positioning bolt needs to be unscrewed, and the transverse rib structure can be pulled out as a whole by the handle without disassembling the chute body, which greatly shortens the disassembly and assembly time.
[0014] 2. In this ball mill feed chute, multiple sets of transverse ribs form a stepped recessed area on the material drop plate. When the material slides down, it is buffered by the steps, which reduces the direct impact of the raw material on the liner. At the same time, the transverse ribs are distributed at intervals, so that the raw material accumulates at the bottom of the liner to form a thin material layer. Subsequent raw material impacts the thin material layer to achieve "material hitting material", which further reduces the wear of the liner and extends the service life of the chute.
[0015] 3. The ball mill feed chute has a liner consisting of a discharge plate and a sliding plate, which can be replaced in different areas to improve maintenance efficiency and reduce maintenance costs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model embodiment discloses a ball mill feed chute, according to the appendix... Figure 1 As shown, it includes a tank body 1 and a horizontal rib structure 2, with the horizontal rib structure 2 inserted into the inner side of the tank body 1.
[0024] The transverse ribs 23 are inserted into the side plate 11 through the insertion hole 111 and fixed with the positioning bolts 24 and the threaded hole 112. During disassembly, only the positioning bolts 25 need to be unscrewed, and the transverse rib structure 2 can be pulled out as a whole through the handle 22 without disassembling the trough body 1, which greatly shortens the disassembly and assembly time. Multiple sets of transverse ribs 23 form a stepped recessed area on the material drop plate 121. When the material slides down, it is buffered by the steps, which reduces the direct impact of the raw material on the liner plate 12. At the same time, the transverse ribs 23 are distributed at intervals, so that the raw material accumulates at the bottom of the liner plate 12 to form a thin material layer. The subsequent impact of the raw material on the thin material layer achieves "material hitting material", which further reduces the wear of the liner plate 12 and extends the service life of the chute. The liner plate 12 is provided with two parts: the material drop plate 121 and the sliding plate 122. Different areas can be replaced, which improves maintenance efficiency and reduces maintenance costs.
[0025] According to the appendix Figures 1 to 3 As shown, further, the side plates 11 of the tank body 1 are provided in two sets, symmetrically distributed on both sides of the liner 12. Multiple insertion holes 111 are evenly opened on the left side plate 11. The material drop plate 121 of the liner 12 is tightly connected with the sliding plate 122. Bolt holes are opened on both the left and right sides of the material drop plate 121 and the sliding plate 122. The connecting bolts 123 pass through the bolt holes to fix the two. The top of the material drop plate 121 and the sliding plate 122 are integrally formed with protrusions. The width of the protrusions is adapted to the distance between the two sets of side plates 11. After the protrusions are inserted between the side plates 11, the bolt holes of the side plates 11 are aligned with the bolt holes of the liner 12. The connecting bolts 123 pass through the bolt holes of the side plates 11 to fix the side plates 11 and the liner 12.
[0026] According to the appendix Figures 1 to 4As shown, the connecting plate 21 of the horizontal rib structure 2 is a rectangular plate with a U-shaped handle 22 welded to its outer side for easy gripping and operation; multiple horizontal ribs 23 are welded to the inner side of the connecting plate 21, the diameter of the horizontal ribs 23 is adapted to the diameter of the insertion hole 111, and the end of the horizontal rib 23 away from the connecting plate 21 is inserted into the insertion hole 111; the connecting plate 21 has a through hole corresponding to the threaded hole 112, and the positioning bolt 24 passes through the through hole and is screwed into the threaded hole 112 to fix the horizontal rib structure 2 to the groove 1; the groove 25 at the bottom of the connecting plate 21 is an arc-shaped groove, the position of which corresponds to the head of the connecting bolt 123. During assembly, the head of the connecting bolt 123 is embedded in the groove 25 to avoid interference between the connecting plate 21 and the connecting bolt 123.
[0027] Working principle: When in use, the material slides from the slide plate 122 onto the discharge plate 121, and after being buffered by the stepped recessed area formed by the transverse rib 23, it smoothly enters the ball mill; when the transverse rib 23 is worn and needs to be replaced, unscrew the positioning bolt 24, hold the handle 22 to pull out the transverse rib structure 2, replace the new transverse rib structure 2 and then fix it again. The operation is convenient.
