Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a feeding structure and a crusher. Background Technology

[0002] A crusher is used to crush large-diameter materials into smaller ones. A crusher generally consists of a casing and crushing rollers installed inside the casing. The material to be crushed is fed into the casing through a feed hopper located at the top. The crushing rollers impact the material, causing it to be crushed. The material is then discharged through a discharge hopper located at the bottom of the casing. During actual operation, some materials generate a significant amount of dust during crushing, leading to a large amount of dust overflowing from the feed hopper and negatively impacting the surrounding environment. In existing technology, a dust extraction hood is typically installed above the feed hopper, connected to an exhaust fan, to remove the overflowing dust and reduce its harmful effects. However, this dust extraction hood often needs to be placed quite close to the feed hopper, obstructing the feeding process and hindering smooth material feeding. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a feeding structure that solves the problem that requires dust removal equipment to be installed close to the top of the feeding hopper, which would affect the smooth feeding process.

[0004] According to an embodiment of the present invention, a feeding structure includes a feeding hopper, which includes a cylindrical section and a bucket-shaped section connected to the lower end of the cylindrical section. A support ring is fixedly connected to the inner wall of the lower end of the cylindrical section. The support ring is engaged with a dividing hopper extending from the cylindrical section to the bucket-shaped section. The dividing hopper and the bucket-shaped section have a first outlet and a second outlet, respectively, with the first outlet being smaller than the second outlet. A laterally extending mounting pipe is also connected to the bucket-shaped section. The mounting pipe has an inlet end located inside the bucket-shaped section and a connecting end located outside the bucket-shaped section. The connecting end is detachably connected to an exhaust pipe. The partition hopper in this design divides the feed hopper into upper and lower chambers. The lower chamber is connected to the crusher. Material is fed into the upper chamber, then enters the lower chamber through the first outlet, and finally enters the crusher through the second outlet. Dust generated during the crushing process rises into the lower chamber. An external exhaust pipe can be connected to an existing exhaust fan, allowing dust to be extracted from the lower chamber through the installation pipe. This significantly reduces the amount of dust entering the cylindrical section through the first outlet, thus achieving dust removal. This eliminates the need for a structure above the feed hopper, preventing obstruction of material feeding and solving the problem in existing technologies where dust removal equipment needs to be installed close to the feed hopper, affecting smooth material feeding.

[0005] Furthermore, the inlet opening is angled toward the second outlet and located diagonally below the first outlet.

[0006] Furthermore, an installation sleeve is fixedly connected to the upper end of the bucket-shaped section, and an installation tube passes through the installation sleeve and is detachably connected to the installation sleeve.

[0007] Furthermore, the end of the connection is connected to the exhaust pipe via a first flange.

[0008] Furthermore, the bucket-shaped section and the straight section are connected by a second flange.

[0009] Furthermore, a groove is recessed on the support ring, a support cylinder is fixedly connected to the upper end of the dividing hopper, and a retaining ring that fits into the groove is fixedly connected to the lower end face of the support cylinder.

[0010] Furthermore, the upper inner ring wall of the support ring is inclined and connected to the inner wall of the support cylinder.

[0011] A crusher including the aforementioned feeding structure is also provided.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The design divides the feed hopper into upper and lower chambers. The lower chamber is connected to the crusher. Material is fed into the upper chamber, then enters the lower chamber through the first outlet, and finally exits into the crusher through the second outlet. Dust generated during crushing rises into the lower chamber. An external exhaust pipe can be connected to an existing exhaust fan, allowing dust to be extracted from the lower chamber through the installation pipe. This significantly reduces the amount of dust entering the cylindrical section through the first outlet, thus achieving dust removal. This design eliminates the need for a structure above the feed hopper, preventing obstruction of material feeding and solving the problem in existing technologies where dust removal equipment needs to be installed close to the feed hopper, affecting smooth material feeding.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] In an exemplary implementation, such as Figure 1 , 2 As shown, this embodiment provides a crusher with a feeding structure. The feeding structure includes a feeding hopper, which comprises a cylindrical section 1 and a bucket-shaped section 2 connected to the lower end of the cylindrical section 1. The upper end of the cylindrical section 1 is a material inlet. A support ring 3 is fixedly connected to the inner wall of the lower end of the cylindrical section 1. The support ring 3 is engaged with a dividing hopper 4 extending from the cylindrical section 1 to the bucket-shaped section 2. The dividing hopper 4 and the bucket-shaped section 2 each have a first outlet 5 and a second outlet 6, with the first outlet 5 being smaller than the second outlet 6. The dividing hopper 4 divides the feeding hopper into an upper chamber 14 and a lower chamber 15. After the material is fed into the upper chamber 14 from the upper end of the cylindrical section 1, it passes through the first outlet 5 to the lower chamber 15, and then passes through the second outlet 6 into the crusher, thus achieving feeding. Furthermore, in this embodiment, a laterally extending installation pipe 7 is also connected to the bucket-shaped section 2. The installation pipe 7 has an inlet end located inside the bucket-shaped section 2 and a connecting end located outside the bucket-shaped section 2. The connecting end can... The installation pipe 8 is detached and connected. The exhaust pipe 8 can be connected to an exhaust fan similar to that in the prior art. When the exhaust fan is running, the installation pipe 7 will generate suction. The dust generated during the operation of the crusher will go through the second outlet 6 to the lower chamber 15. Most of the dust will be sucked into the installation pipe 7 and finally removed by the exhaust fan. This can significantly reduce the amount of dust that passes through the first outlet 5 into the cylindrical section 1, thereby achieving the purpose of dust removal. This eliminates the need to set up a structure above the feed hopper, thus not obstructing the feeding of materials. It solves the problem in the prior art that the dust removal equipment needs to be set up close above the feed hopper, which will affect the smooth feeding process. Furthermore, the inlet end is set to allow dust to enter the installation pipe 7 when the exhaust fan is running. The inlet end opening is inclined towards the second outlet 6 and located diagonally below the first outlet 5. This setting allows the dust to enter the installation pipe 7 more smoothly and be removed, minimizing the amount of dust that passes through the first outlet 5 into the upper chamber 14.

[0021] like Figure 1As shown, the upper end of the bucket-shaped section 2 is fixedly connected to the mounting sleeve 9, and the mounting pipe 7 passes through the mounting sleeve 9 and is detachably connected to the mounting sleeve 9. The end of the mounting pipe 7 is connected to the exhaust pipe 8 through the first flange 10, so that the mounting pipe 7 and the exhaust pipe 8 can be disassembled to facilitate regular cleaning of the inside of the mounting pipe 7.

[0022] like Figure 1 , 2 As shown, the cylindrical section 1 and the bucket-shaped section 2 in this scheme are detachable. Specifically, the bucket-shaped section 2 and the straight section are connected by the second flange 11, which allows for easy disassembly and regular cleaning of the internal structure.

[0023] like Figure 1 , 2 As shown in the more detailed scheme, the support ring 3 is recessed with an annular groove, the upper end of the partition hopper 4 is fixedly connected to the support cylinder 13, and the lower end face of the support cylinder 13 is fixedly connected to the retaining ring 12 that is inserted into the annular groove. The support ring 3 is used to support the internal partition hopper 4, that is, the partition hopper 4 can be removed upwards. This allows for internal cleaning without disassembling the cylindrical section 1 and the hopper section 2. The upper inner ring wall of the support ring 3 is inclined and connected to the inner wall of the support cylinder 13, which can avoid generating a large amount of material residue on the support ring 3.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
