Description

Technical Field

[0001] This utility model relates to the field of crusher feeding auxiliary components, specifically to a hopper structure that reduces crusher wear. Background Technology

[0002] Currently, crushers are indispensable production equipment in crushing production lines of industries such as ore, coal mining, and metallurgy. Among them, jaw crushers are widely used in raw ore crushing and material processing, playing a vital role in the development of modern industry.

[0003] In practical applications of jaw crushers, it is usually necessary to install a hopper at the feed inlet to facilitate the collection and feeding of ore conveyed by the conveyor belt into the jaw crusher. However, existing hoppers typically only serve the function of collecting ore. This results in most of the ore falling into the hopper and then crashing into the jaw crusher's internal chamber, causing significant and continuous impact and accelerating wear on the inside of the jaw crusher's internal chamber. Utility Model Content

[0004] The purpose of this utility model is to provide a hopper structure that reduces wear on crushers in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a hopper structure for reducing wear on a crusher, including a hopper body. The lower part of the hopper body is a straight-tube-shaped feeding hopper. An inclined sliding plate is provided between the two sides inside the feeding hopper. The front edge of the sliding plate extends to the inner front part of the feeding hopper and is close to the top of the feeding hopper. The rear edge of the sliding plate extends to the inner middle part of the feeding hopper and is close to the bottom of the feeding hopper.

[0007] The front of both sides of the inside of the feeding hopper is equipped with a disassembly assembly. The top of the disassembly assembly is fixedly connected to the bottom surface of the front edge of the sliding plate through a connecting piece. The sliding plate is detachably fixed inside the feeding hopper through the disassembly assembly.

[0008] Preferably, the upper part of the hopper body is a funnel-shaped receiving hopper.

[0009] Preferably, the bottom periphery of the hopper is fixed with a mounting plate for installation at the feed inlet of the crusher.

[0010] Preferably, the sliding plate is a rectangular steel plate with a lateral width dimension matching the lateral width dimension inside the hopper, and the top surface of the sliding plate is covered with a buffer liner of buffer material.

[0011] Preferably, the vertical distance between the rear edge of the sliding plate and the inner rear wall of the hopper is not less than half of the longitudinal width of the hopper.

[0012] Preferably, each of the disassembly and assembly components includes a mating seat and a fixing sleeve. The mating seats are vertically fixed to both sides of the bottom surface of the front edge of the sliding plate through the assembly connector. The outer end faces of the mating seats on both sides, which are far apart from each other, are provided with limiting holes in the transverse direction. The fixing sleeves are vertically fixed to the front of both sides of the inside of the hopper. The top surface of each fixing sleeve is provided with a mating groove in the vertical direction. The mating seats pass through the corresponding mating grooves in a vertical sliding fit. The outer end faces of the fixing sleeves on both sides, which are far apart from each other, are provided with mounting holes in the transverse direction. The front of both sides of the hopper is provided with mating holes in the transverse direction. The mounting holes and mating holes are through holes and are transversely coaxial with the limiting holes on the corresponding sides. The mounting holes and mating holes on the same side are respectively inserted into the limiting rods in a sliding fit in the transverse direction. The ends of the limiting rods on both sides that are close to each other are coaxially slidingly fitted with the corresponding limiting holes.

[0013] Preferably, the outer ends of the limiting rods on both sides, which are far apart from each other, are coaxially fixed with handles. The portion of the limiting rod located between the corresponding handle and the outer end face of the hopper is coaxially fitted with a spring, and the two ends of the spring are respectively fixedly connected to the corresponding handle and the outer end face of the hopper.

[0014] Preferably, the horizontal cross-sectional shape of the mating seat and the mating groove is rectangular, the mating groove is a blind groove in the vertical direction and is opened from top to bottom, and the bottom end of the mating seat is in close contact with the bottom of the corresponding mating groove.

[0015] Preferably, each of the combined connectors includes a U-shaped mounting groove opened on the top surface of the mating seat and a connecting plate vertically fixed to the bottom edge of the sliding plate. The connecting plates are all inserted into the U-shaped mounting groove on the corresponding side in a vertical sliding fit. The top of each mating seat is fitted with a locking member that passes through the U-shaped mounting groove and the connecting plate on the corresponding side in sequence.

[0016] Preferably, the bottom surface of the connecting plate is in contact with the bottom of the corresponding U-shaped mounting groove, and the locking components are all bolts with nuts.

[0017] The aforementioned hopper structure for reducing crusher wear, specifically when using the hopper body to feed ore into the crusher, involves assembling the hopper body at the crusher's feed inlet using the mounting plate. Since sliding plates are provided between the two sides of the hopper's interior, with the front edge of the sliding plates extending to the inner front of the hopper and near its top, and the rear edge extending to the inner middle of the hopper and near its bottom, the inclined sliding plates can buffer and receive the ore falling into the hopper, preventing it from being crushed. The raw stone material enters the jaw crusher chamber directly through free fall. By allowing the ore to slide along the inclined direction of the sliding plate into the jaw crusher chamber, the impact on the interior of the chamber is reduced, thus mitigating wear. Furthermore, because the bottom front edge of the sliding plate is connected to the disassembly assembly via the connecting piece, the sliding plate can be detachably assembled inside the hopper through the vertical sliding engagement of the mating seat and the mating groove, and the horizontal sliding engagement of the limiting rod and the limiting hole. Only the external pulling of the connecting piece is required... After the limiting rod disengages from the limiting hole, the mating seat can slide vertically out of the mating groove, thereby allowing the sliding plate to be lifted and detached from the hopper and the hopper body to be removed. The assembly and disassembly of the sliding plate inside the hopper is simple and easy to implement. It facilitates the quick assembly of the sliding plate inside the hopper for receiving and buffering ore raw materials, and also facilitates the subsequent disassembly of the sliding plate from the hopper and removal of the hopper body for regular inspection and maintenance. Since the assembly connector includes the U-shaped mounting groove opened on the top surface of the mating seat and the connecting plate vertically fixed to the bottom edge of the sliding plate, it can then be connected via... The method of vertically inserting the connecting plate into the U-shaped mounting groove and then horizontally inserting the locking member allows the sliding plate and the disassembly assembly to be quickly assembled together. At the same time, the connecting plate and the U-shaped mounting groove can be separated simply by removing the locking member, thus enabling the sliding plate and the disassembly assembly to be quickly separated. The assembly and disassembly of the sliding plate and the disassembly assembly are simple and easy to implement. This facilitates the quick assembly of the sliding plate and the disassembly assembly and their installation into the hopper for use, and also facilitates the subsequent inspection, maintenance and replacement of the sliding plate after separating it from the disassembly assembly.

[0018] The beneficial effects are as follows: 1. The present invention provides a sliding plate between the two sides of the inner hopper of the hopper body. The front edge of the sliding plate extends to the inner front of the hopper and close to the top of the hopper, and the rear edge of the sliding plate extends to the inner middle of the hopper and close to the bottom of the hopper. In this way, the ore material falling into the hopper body can be received and buffered by the inclined sliding plate, avoiding the ore material from entering the jaw crusher hopper directly in a free fall. By letting the ore material slide into the jaw crusher hopper along the inclined direction of the sliding plate, the impact on the inside of the jaw crusher hopper can be reduced, which is conducive to reducing the wear inside the jaw crusher hopper.

[0019] 2. After the bottom edge of the sliding plate is connected to the disassembly assembly by the connecting parts, the sliding plate can be detachably assembled inside the hopper by the vertical sliding engagement of the mating seat and the mating groove of the disassembly assembly and the horizontal sliding engagement of the limiting rod and the limiting hole. Only by pulling the limiting rod out of the limiting hole can the mating seat slide vertically out of the mating groove, so that the sliding plate can be lifted and removed from the hopper and the hopper body can be taken out. The assembly and disassembly of the sliding plate inside the hopper is simple and easy to implement. It is convenient to quickly assemble the sliding plate inside the hopper for receiving and buffering ore raw materials, and it is also convenient to remove the sliding plate from the hopper and take out the hopper body for regular inspection and maintenance.

[0020] 3. The assembly connector includes a U-shaped mounting groove on the top surface of the mating seat and a connecting plate vertically fixed to the bottom edge of the slide plate. By vertically inserting the connecting plate into the U-shaped mounting groove and then horizontally inserting a locking device, the slide plate and the assembly can be quickly assembled together. At the same time, the connecting plate and the U-shaped mounting groove can be separated by simply removing the locking device. This allows the slide plate and the assembly to be quickly separated. The assembly and disassembly of the slide plate and the assembly are simple and easy to implement. It is convenient to quickly assemble the slide plate and the assembly and install it into the hopper for use. It is also convenient to separate the slide plate and the assembly for inspection, maintenance and replacement of the slide plate later. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] See Figures 1-8As shown, this utility model provides a hopper structure to reduce wear on a crusher, including a hopper body 1. The lower part of the hopper body 1 is a straight pipe-shaped feeding hopper 102. An inclined sliding plate 3 is provided between the two sides inside the feeding hopper 102. The front edge of the sliding plate 3 extends to the inner front part of the feeding hopper 102 and is close to the top of the feeding hopper 102, and the rear edge of the sliding plate 3 extends to the inner middle part of the feeding hopper 102 and is close to the bottom of the feeding hopper 102. The purpose of this arrangement is to receive and buffer the ore raw materials falling into the hopper body 1 by means of the inclined sliding plate 3, so as to avoid the ore raw materials entering the jaw crusher hopper directly in a free fall. Thus, by letting the ore raw materials slide into the jaw crusher hopper along the inclined direction of the sliding plate 3, the impact on the jaw crusher hopper can be reduced.

[0034] See Figures 1-8 As shown, the front of both sides of the inner side of the hopper 102 is equipped with a disassembly assembly 2, and the sliding plate 3 is detachably fixed inside the hopper 102 through the disassembly assembly 2. Specifically, each disassembly assembly 2 includes a mating seat 206 and a fixing sleeve 204. The front edge bottom surface of the sliding plate 3 is vertically fixed with mating seats 206 on both sides through a combination connector 4. The outer end faces of the mating seats 206 on both sides are horizontally provided with limit holes 209. The front of both sides of the hopper 102 is vertically fixed with fixing sleeves 204, and the top surface of the fixing sleeves 204 is vertically provided with mating grooves 205. The mating seats 206 pass through the corresponding mating grooves 205 in a vertical sliding fit. The outer end faces of the fixing sleeves 204 on both sides are horizontally provided with mounting holes 208. The front of both sides of the hopper 102 is horizontally provided with mating holes 203 for installation. Both hole 208 and mating hole 203 are through holes and are horizontally coaxially aligned with the corresponding side limiting hole 209. The mounting hole 208 and mating hole 203 on the same side are respectively slidably fitted with the limiting rod 207 along the horizontal coaxial direction. The ends of the limiting rods 207 on both sides are slidably fitted with the corresponding limiting hole 209. The reason for this arrangement is that by vertically sliding the mating seat 206 of the disassembly assembly 2 with the mating groove 205 and horizontally sliding the limiting rod 207 with the limiting hole 209, the sliding plate 3 can be detachably assembled inside the hopper 102. Only by pulling the limiting rod 207 out of the limiting hole 209 can the mating seat 206 be vertically slid out of the mating groove 205. In this way, the sliding plate 3 can be lifted and removed from the hopper 102 and the hopper body 1 can be taken out. The assembly and disassembly of the sliding plate 3 inside the hopper 102 is simple and easy to implement.

[0035] See Figures 1-8As shown, the top of each assembly 2 is fixedly connected to the bottom surface of the front edge of the slide plate 3 via a connecting piece 4. Specifically, each connecting piece 4 includes a U-shaped mounting groove 402 opened on the top surface of the mating seat 206 and a connecting plate 401 vertically fixed to the bottom surface of the upper edge of the slide plate 3. The connecting plate 401 is inserted into the U-shaped mounting groove 402 on the corresponding side in a vertical sliding fit. Each mating seat 206 is equipped with a locking piece 403 inserted horizontally on its top, and the locking pieces 403 pass through the corresponding side in sequence. The U-shaped mounting groove 402 and the connecting plate 401 are designed so that the sliding plate 3 and the disassembly assembly 2 can be quickly assembled by inserting the connecting plate 401 vertically into the U-shaped mounting groove 402 and then inserting the locking piece 403 horizontally. At the same time, the connecting plate 401 and the U-shaped mounting groove 402 can be separated by simply removing the locking piece 403. This allows the sliding plate 3 and the disassembly assembly 2 to be quickly separated. The assembly and disassembly of the sliding plate 3 and the disassembly assembly 2 are simple and easy to implement.

[0036] See Figures 1-5 As shown, the following optimizations were made to the hopper body 1, the disassembly assembly 2, and the assembly connector 4. Specifically, for the hopper body 1, the upper part of the hopper body 1 is a funnel-shaped receiving hopper 101, which facilitates the hopper body 1 to have a good and reliable ore raw material collection capacity. Optionally, an installation plate 103 for installation at the crusher inlet is fixed to the bottom periphery of the discharge hopper 102. Preferably, the installation plate 103 is a rectangular flange plate with multiple through holes evenly distributed around its circumference, facilitating the assembly and installation of the hopper body 1 at the crusher inlet using the installation plate 103. Specifically, installation and fixation can be achieved by adding screws through the through holes. Furthermore, the sliding plate 3 is a rectangular steel plate with a lateral width matching the internal lateral width of the discharge hopper 102, and the top surface of the sliding plate 3 is covered with a buffer liner 301 of buffer material. This design allows the buffer liner 301 to directly contact the ore raw material, thus slowing down the wear process of the sliding plate 3. Optionally, the vertical distance between the rear edge of the sliding plate 3 and the inner rear wall of the hopper 102 is not less than half the longitudinal width of the hopper 102, so that the rear edge of the sliding plate 3 can smoothly slide the ore material into the inner wall of the crusher chamber.

[0037] See Figures 1-8As shown, specifically for the disassembly assembly 2 and the assembly connector 4, the outer ends of the limiting rods 207 on both sides are coaxially fixed with handles 201. The portion of the limiting rod 207 located between the corresponding handle 201 and the outer end face of the hopper 102 is coaxially fitted with a spring 202, and the two ends of the spring 202 are fixedly connected to the corresponding handle 201 and the outer end face of the hopper 102, respectively, so that the limiting rod 207 can be pulled by applying force by holding the handle 201, and the spring force of the spring 202 can make the limiting rod 207 automatically return to its original position after being released. Alternatively, the horizontal cross-sectional shape of both the mating seat 206 and the mating groove 205 is rectangular. The mating groove 205 is a blind groove in the vertical direction and is opened from top to bottom. The bottom end of the mating seat 206 is in close contact with the bottom of the corresponding mating groove 205. This arrangement firstly facilitates the positioning and guiding design of the mating seat 206 when it slides vertically along the mating groove 205. At the same time, during the process of the mating seat 206 sliding vertically along the mating groove 205, when the limiting hole 209 slides vertically with the mating seat 206 to be coaxial with the limiting rod 207, the bottom end of the mating seat 206 is in close contact with the bottom of the corresponding mating groove 205, which provides a clear indication. Alternatively, the bottom surface of the connecting plate 401 can be in contact with the bottom of the corresponding U-shaped mounting groove 402, and the locking parts 403 can be bolts with nuts. This arrangement firstly ensures that the bottom of the connecting plate 401 can be stably supported, and secondly, it facilitates the subsequent disassembly and assembly of the locking parts 403 with the help of a wrench.

[0038] With the above structure, specifically when using the hopper body 1 to feed ore raw materials into the crusher, the hopper body 1 is assembled and installed at the feed inlet of the crusher with the help of the mounting plate 103. Since a sliding plate 3 is provided between the two sides inside the hopper 102 of the hopper body 1, and the front edge of the sliding plate 3 extends to the inner front part of the hopper 102 and is close to the top of the hopper 102, and the rear edge of the sliding plate 3 extends to the inner middle part of the hopper 102 and is close to the bottom of the hopper 102, the ore raw materials falling into the hopper body 1 can be received and buffered by the inclined sliding plate 3, avoiding the ore raw materials from falling directly into the hopper body 1. The ore material enters the jaw crusher chamber by sliding along the inclined direction of the sliding plate 3, thus reducing the impact on the inside of the jaw crusher chamber and mitigating wear. Because the bottom front edge of the sliding plate 3 is connected to the disassembly assembly 2 via the connecting piece 4, the sliding plate 3 can be detachably assembled inside the hopper 102 through the vertical sliding engagement of the mating seat 206 and the mating groove 205, and the horizontal sliding engagement of the limiting rod 207 and the limiting hole 209. Only the external pulling of the limiting rod 207 is needed to disassemble it. After the positioning hole 209 is reached, the mating seat 206 can slide vertically out of the mating groove 205, thereby allowing the sliding plate 3 to be lifted and detached from the hopper 102 and the hopper body 1 to be removed. The assembly and disassembly of the sliding plate 3 inside the hopper 102 is simple and easy to implement. It is convenient to quickly assemble the sliding plate 3 inside the hopper 102 for receiving and buffering ore raw materials, and it is also convenient to remove the sliding plate 3 from the hopper 102 and remove the hopper body 1 for regular inspection and maintenance. Since the assembly connector 4 includes a U-shaped mounting groove 402 opened on the top surface of the mating seat 206 and a connecting plate 401 vertically fixed to the bottom surface of the upper edge of the sliding plate 3, it can then be connected by... The method of vertically inserting the connecting plate 401 into the U-shaped mounting groove 402 and then horizontally inserting the locking part 403 allows the sliding plate 3 and the disassembly assembly 2 to be quickly assembled together. At the same time, the connecting plate 401 and the U-shaped mounting groove 402 can be separated by simply removing the locking part 403. This allows the sliding plate 3 and the disassembly assembly 2 to be quickly separated. The assembly and disassembly of the sliding plate 3 and the disassembly assembly 2 are simple and easy to implement. It is convenient to quickly assemble the sliding plate 3 and the disassembly assembly 2 together and put them into the hopper 102 for use. It is also convenient to separate the sliding plate 3 and the disassembly assembly 2 for subsequent inspection, maintenance and replacement of the sliding plate 3.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
