Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically to a high wear-resistant and convenient chute wear-resistant lining structure. Background Technology

[0002] In mining production, chutes are key equipment for ore transportation, and the wear resistance of their linings directly affects production efficiency and cost. Traditional chute linings generally use finished wear-resistant manganese steel lining plates, relying on the hardness of manganese steel to resist the impact of ore, and have been widely used in mining transportation systems for a long time.

[0003] However, existing manganese steel liners have many problems. For ores with larger particle sizes, manganese steel liners wear out quickly and have a short service life, requiring frequent shutdowns for repair or replacement, which seriously affects the stability of production. At the same time, manganese steel liners are large and heavy, requiring hoisting equipment for handling, and are extremely difficult to install in confined spaces. In addition, these liners require special customization, have long delivery cycles, and have high material costs, which not only increases production input but also brings inconvenience to continuous mine production. To address these issues, we propose a highly wear-resistant and convenient chute wear-resistant liner structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a highly wear-resistant and convenient chute wear-resistant liner structure, thus solving the aforementioned problems.

[0023] The wear-resistant liner assembly for the chute is installed inside the mounting groove 5. The wear-resistant liner assembly for the chute includes a bottom liner 2, a mesh liner 3, and steel balls 4.

The top of the bottom liner 2 is provided with a mesh liner 3, and a set of steel balls 4 are linearly distributed between the mesh liner 3 and the bottom liner 2.

[0024] Furthermore, the mounting groove 5 has an inlet / outlet 6 at its shaft end, and a sliding groove 7 is provided on the top of the two opposite sides inside the mounting groove 5. The inlet / outlet 6 has two axially symmetrically distributed connecting holes 8 on the two opposite sides of its shaft end. The mounting groove 5 is placed at the bottom of the stuffing box frame 1. The stuffing box frame 1 is made of manganese steel plate, which is easy to obtain. When the chute is put into operation, the top of the stuffing box frame 1 is the inlet and the bottom is the outlet, and the mounting groove 5 is in an inclined state at this time.

[0025] Furthermore, the bottom liner 2 is mainly a rectangular plate, and the bottom liner 2 has a mating plate 9 at its shaft end, which corresponds to and fits into the inlet / outlet slot 6. The bottom liner 2 has two axially symmetrically distributed connecting strips 11 on its two opposite sides, which are perpendicular to the mating plate 9. Each connecting strip 11 has a connecting hole 12 at both shaft ends. The top of the bottom liner 2 has a set of equidistantly distributed rolling grooves 13, which are parallel to the connecting strips 11. The bottom liner 2 is placed horizontally, and an appropriate number of steel balls 4 are placed inside the rolling grooves 13 and spread out. Then, the mesh liner 3 is placed on top of the bottom liner 2, and the positions of the steel balls 4 inside the rolling grooves 13 are adjusted so that the steel balls 4 are aligned with the mesh. The mesh holes 15 of the grid liner 3 correspond to each other. Four sets of connecting holes 17 and 12 are connected by adapter bolts to complete the assembly of the chute wear-resistant liner component. The steel balls 4 can rotate freely inside the bottom liner 2 and the grid liner 3. Then, the chute wear-resistant liner component is inserted into the installation groove 5, and the connecting holes 1 and 2 are connected by adapter bolts to complete the overall assembly and fixation. It can then be put into operation in the mining area. The rolling steel balls 4 can greatly reduce the impact of stones and facilitate the rapid flow of stones. This chute wear-resistant liner component can greatly improve wear resistance and extend service life. At the same time, the overall structure is simple and lightweight, and can be handled manually, reducing the difficulty of installation and replacement.

[0026] Furthermore, the mating plate 9 has two symmetrically distributed connecting holes 10 on its two opposite sides. The connecting holes 10 are connected to the connecting holes 8 by means of matching bolts. The mating plate 9 also has a handle 14 on its side wall. The connecting holes 10 and 8 serve to fix the wear-resistant lining assembly of the chute, while the handle 14 facilitates maintenance personnel to pull out the wear-resistant lining assembly of the chute.

[0027] Furthermore, the end face of the mesh liner 3 is provided with a set of linearly distributed mesh holes 15, and the mesh holes 15 correspond to the rolling groove 13. Limiting slides 16 are provided on two opposite sides of the top of the mesh liner 3. The bottom of the limiting slides 16 is in contact with the connecting strip 11, and the limiting slides 16 are slidably connected to the inside of the sliding groove 7. Connecting holes 17 are provided on both ends of the limiting slides 16. The connecting holes 17 are connected to the connecting holes 12 by adapter bolts. A set of equally spaced anti-detachment blocks 18 are provided on the bottom side of the mesh liner 3. The anti-detachment block 18 is placed inside the rolling groove 13. The mesh liner 3 and the steel ball 4 are installed in a mesh pattern to ensure the robustness and durability of the wear-resistant liner assembly of the chute. At the same time, the anti-detachment block 18 prevents the steel ball 4 from detaching from the rolling groove 13 and protects the steel ball 4. The limiting slide 16 and the connecting strip 11 are placed inside the slide groove 7. While playing a limiting and guiding role, they also protect the connecting bolts inside the connecting hole 17 and the connecting hole 12, preventing them from being deformed by stone impact, and facilitating subsequent disassembly and replacement work.

[0028] Furthermore, the steel ball 4 is positioned between the grid hole 15 and the rolling groove 13, with the top of the steel ball 4 passing through the grid hole 15. The materials used for the steel ball 4, the bottom liner 2, and the grid liner 3 are all commonly used mining materials, which are easy to obtain. The function of protecting the chute is achieved with simple materials, thus ensuring long-term and stable production.

[0048] Working principle: The high wear-resistant and portable chute wear-resistant liner structure is correctly installed according to the diagram. During operation, the stuffing box frame 1 provides support as the overall skeleton. It is made of manganese steel plate and has a bent box structure. The top is the inlet and the bottom is the outlet. The installation groove 5 at the bottom is inclined to adapt to the material flow path. The chute wear-resistant liner assembly is installed in the installation groove 5 through the inlet / outlet 6. The bottom liner 2 slides with the sliding groove 7 of the installation groove 5 via the connecting strip 11. The mating plate 9 fits against the inlet / outlet 6. Steel balls 4 are provided in the rolling groove 13 at the top of the bottom liner 2. The grid liner 3 covers the bottom liner 2 through the limiting strip 16 and the sliding groove 7. The grid holes 15 correspond to the rolling groove 13, allowing the steel balls 4 to be partially exposed. It can rotate freely, while the anti-detachment block 18 restricts the steel ball 4 from detaching from the rolling groove 13. When the ore enters from the feed inlet, the material first contacts the steel ball 4 exposed in the grid hole 15. The steel ball 4 rotates under the impact of the material, converting the direct impact of the material into rolling friction, which greatly reduces the wear on the liner. At the same time, the inclined mounting groove 5 and the rotating steel ball 4 work together to help the material flow quickly along the chute. If maintenance or replacement is required, the wear-resistant liner assembly of the chute can be pulled out by the handle 14, and the bolts of the connecting hole three 12 and the connecting hole four 17 can be removed to separate the components, which can achieve convenient maintenance. Moreover, the materials used in the whole are all commonly used mining materials, which are easy to obtain. The function of protecting the chute can be achieved with simple materials, so as to achieve long-term and stable production.
