Description

Technical Field

[0001] This utility model relates to crushing equipment, and more particularly to a crusher feed inlet device. Background Technology

[0002] Roll crushers are key equipment widely used in metallurgy, mining, and building materials industries for crushing materials of medium to high hardness. In actual production, especially when processing high-hardness materials such as ore pellets, the material is crushed under high-intensity compression between the rollers, often accompanied by violent high-speed particle splashing. However, existing roll crushers mostly use open or fixed baffle structures for their feed inlets, which have significant drawbacks: First, open structures cannot effectively contain splashed material, posing a serious safety threat to operators and the surrounding environment, while also leading to material waste and pollution around the equipment. Second, while some designs using vertically raised baffles can block splashing to some extent, they significantly increase the risk of material accumulation at the inlet, easily causing blockages and material jams, affecting production continuity. Furthermore, some devices with fixed-angle guide plates lack adjustment capabilities, making it difficult to adapt to materials of different particle sizes, moisture content, and flow characteristics. When material characteristics change, problems such as poor flow guidance, uneven feeding, or blockages easily occur, limiting the improvement of crushing efficiency.

[0003] Therefore, there is an urgent need for a feed inlet device that can effectively suppress material splashing, flexibly adapt to different material characteristics, and reduce impact noise and wear, so as to improve the safety, efficiency and reliability of crushing operations. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a crusher feed inlet device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a feed inlet device for a roller crusher, comprising a feed inlet body of the roller crusher, the top of the feed inlet body being connected to the bottom of a straight cylindrical connector, and the top of the straight cylindrical connector being connected to the bottom of a guide channel; a horizontally arranged support plate is fixedly connected to the outer wall of the straight cylindrical connector, and two supports are provided on the support plate, with the guide channel rotatably installed between the two supports; a pair of adjusting inclined bracing mechanisms are also provided on the support plate, one end of the adjusting inclined bracing mechanism being hinged to the support plate, and the other end of the adjusting inclined bracing mechanism being hinged to the side wall of the guide channel, wherein the inclination angle of the guide channel is changed by adjusting the length of the adjusting inclined bracing mechanism; the bottom part of the guide channel extends into the interior of the straight cylindrical connector, and always maintains cooperation with the straight cylindrical connector during the angle adjustment process, without interference or separation.

[0006] Furthermore, coaxial rotating shafts are fixedly provided on both sides of the flow guide channel, and the rotating shafts are rotatably supported in the shaft holes of the corresponding supports, so that the flow guide channel can rotate around the axis of the rotating shaft.

[0007] Furthermore, the adjusting brace mechanism includes an ear seat fixed to the support plate, a threaded rod hinged to the ear seat via a pin, and an adjusting block sleeved on the threaded rod; the adjusting block has a through hole through which the threaded rod passes; and an adjusting nut is provided on each side of the adjusting block, and each adjusting nut is threadedly connected to the threaded rod, the two adjusting nuts being used to lock the position of the adjusting block; the adjusting block also has a blind hole, the blind hole being clearance-fitted with the shaft portion of a flange shaft, the flange portion of the flange shaft being fixedly connected to the side wall of the guide channel.

[0008] Furthermore, the bottom of the straight cylindrical connector is detachably connected to the top of the inlet body by circumferentially distributed fasteners, and an annular shock-absorbing pad is provided between the connection interface of the straight cylindrical connector and the inlet body.

[0009] Furthermore, the guide channel includes a straight portion and an inclined portion fixedly connected; the straight portion is inserted into the interior of the straight cylindrical connector, and the adjusting inclined support mechanism is connected to the side wall of the inclined portion; when the guide channel rotates around the pivot to adjust the angle, the straight portion is always located inside the straight cylindrical connector, and the outer wall of the straight portion and the inner wall of the straight cylindrical connector maintain a clearance fit so that the two do not structurally interfere with each other.

[0010] Furthermore, the inclination angle of the inclined portion of the guide channel is adjusted by the adjusting brace mechanism, with an adjustment range of 30 to 45 degrees. Within this adjustment range, the outer wall of the straight portion and the inner wall of the straight cylindrical connector always maintain a clearance fit. This means that when adjusting the angle, there is sufficient room for movement between them, preventing mutual friction or jamming, ensuring a smooth adjustment process, and also avoiding the possibility of blockage due to increased friction.

[0011] Furthermore, the inner wall at the top of the guide channel is provided with an elastic buffer layer.

[0012] Furthermore, a swing blade that can swing freely is hinged to the front and rear sides of the bottom of the straight section of the guide channel, and fixed side baffles are provided on the left and right sides of the bottom of the straight section.

[0013] Furthermore, both hinges are connected to the sidewall of the straight section via their respective hinge structures, and the free ends of the hinges hang down naturally under the action of gravity.

[0014] Furthermore, a maintenance port is provided on one side wall of the guide channel, and a detachable maintenance cover is connected to the maintenance port.

[0015] Compared with the prior art, this utility model has the following advantages.

[0016] 1. This utility model adds a guide channel to the existing feed inlet body. The guide channel is designed with a certain tilt angle, which can effectively block the flying of gravel during the crushing of hard materials. At the same time, an elastic buffer layer material is installed at the top of the guide channel to prevent the flying gravel from directly hitting the metal guide channel wall and causing damage to the guide channel wall, while also reducing the noise during impact.

[0017] 2. In order to adapt to the flowability requirements of different materials, this utility model has an adjustable angle design for the flow channel. For materials with poor flowability, the angle of the flow channel needs to be adjusted to be larger so that the material can quickly enter the crusher. For materials with high flowability, the angle of the flow channel needs to be adjusted to be smaller so as to avoid the material from accumulating at the crusher inlet and causing blockage and affecting the crushing effect.

[0018] 3. At the same time, adding shock-absorbing pads at the bottom of the guide channel and the original material inlet interface can effectively reduce the vibration of the crusher during operation from being transmitted to the guide channel. Attached Figure Description

[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0030] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The singular forms “a,” “the,” and “the” as used in the embodiments of this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0031] Depending on the context, words such as “if” or “suppose” used here can be interpreted as “when”, “in response to determination”, or “in response to detection”.

[0032] For ease of understanding, the embodiments of this disclosure will be described in detail first.

[0033] like Figure 1-8 As shown, the feed inlet device of the roller crusher includes a feed inlet body 2 of the roller crusher 1. The top of the feed inlet body 2 is connected to the bottom of a straight cylindrical connector 4, and the top of the straight cylindrical connector 4 is connected to the bottom of a guide channel 5. The bottom of the straight cylindrical connector 4 is detachably connected to the top of the feed inlet body 2 by circumferentially distributed fasteners, and an annular damping pad 3 is provided between the connection interface of the straight cylindrical connector 4 and the feed inlet body 2. The annular damping pad 3 provides vibration isolation at the detachable connection interface, protects the upstream guide and adjustment mechanism from damage caused by the vibration of the crusher body, and ensures reliable connection, compensates for installation deviations, and assists in noise reduction.

[0034] A horizontally arranged support plate 15 is fixedly connected to the outer wall of the straight cylindrical connector 4. Two supports 7 are provided on the support plate 15, and the guide channel 5 is rotatably installed between the two supports 7. Coaxial rotating shafts 8 are fixedly provided on both sides of the guide channel 5. The rotating shafts 8 are rotatably supported in the shaft holes of the corresponding supports 7, so that the guide channel 5 can rotate around the axis of the rotating shafts 8. Specifically, the support plate 15 is sleeved on the outside of the straight cylindrical connector, and the inner wall of the support plate 15 is fixedly connected to the outer wall of the straight cylindrical connector 4, which is used to provide a stable and reliable mounting base and support platform for the guide channel 5, supports 7 and adjusting brace mechanism 9 above.

[0035] The support plate 15 is also provided with a pair of adjusting diagonal bracing mechanisms 9. One end of the adjusting diagonal bracing mechanism 9 is hinged to the support plate 15, and the other end of the adjusting diagonal bracing mechanism 9 is hinged to the side wall of the guide channel 5. The tilt angle of the guide channel 5 can be changed by adjusting the length of the adjusting diagonal bracing mechanism 9. The bottom part of the guide channel 5 extends into the interior of the straight cylinder joint 4, and always maintains cooperation with the straight cylinder joint 4 during the angle adjustment process without interference or separation.

[0036] Operating Description: The guide channel 5 of this utility model is an inclined slide, not a vertical cylinder. When material falls onto the inclined guide channel 5, its gravity is decomposed into two forces: one is a force that presses vertically against the bottom of the channel, and the other is a sliding force that slides downward along the slope. This sliding force continuously "pulls" the material downward, preventing it from stopping and thus fundamentally preventing the formation of "material arching".

[0037] Furthermore, for materials with "poor flowability" (wet, easily adhering), the angle can be increased to make the slope steeper and the sliding force stronger, ensuring that the material can rush down quickly. For materials with "good flowability," the angle can be decreased to control the feeding speed and prevent excessive feeding. This adaptability is something that fixed vertical baffles simply cannot achieve. In other words, this invention eliminates the hidden dangers of vertical baffles, replacing the concept of vertical barriers with the concept of inclined flow guidance. This effectively prevents splashing while significantly improving the flowability of materials, solving the core problem of clogging.

[0038] Preferably, the adjusting brace mechanism 9 includes an ear seat 901 fixed on the support plate 15, a threaded rod 903 hinged to the ear seat 901 via a pin 902, and an adjusting block 904 sleeved on the threaded rod 903. The adjusting block 904 has a through hole through which the threaded rod 903 passes. An adjusting nut 906 is provided on each side of the adjusting block 904, and each adjusting nut 906 is threadedly connected to the threaded rod 903. The two adjusting nuts 906 are used to lock the position of the adjusting block 904. The adjusting block 904 also has a blind hole 907, which is clearance-fitted with the shaft portion of a flange shaft 905. The flange portion of the flange shaft 905 is fixedly connected to the side wall of the guide channel 5. By rotating the adjusting nut 906, the position of the adjusting block 904 on the threaded rod 903 can be adjusted and locked, thereby realizing the angle adjustment and fixation of the guide channel 5.

[0039] Preferably, the guide channel 5 includes a straight portion 501 and an inclined portion 502 fixedly connected; the straight portion 501 is inserted into the interior of the straight cylindrical connector 4, and the adjusting inclined support mechanism 9 is connected to the side wall of the inclined portion 502; when the guide channel 5 rotates around the rotating shaft 8 to adjust the angle, the straight portion 501 is always located inside the straight cylindrical connector 4, and the outer wall of the straight portion 501 and the inner wall of the straight cylindrical connector 4 maintain a gap 16 fit, so that the two do not have structural interference.

[0040] The tilt angle of the inclined part 502 of the guide channel 5 is adjusted by adjusting the inclined support mechanism 9, and the angle adjustment range is 30 degrees to 45 degrees; within the angle adjustment range, the outer wall of the straight part 501 and the inner wall of the straight cylinder connector 4 always maintain a clearance fit.

[0041] The top inner wall of the guide channel 5 is provided with an elastic buffer layer 11. It significantly reduces noise and vibration by absorbing impact energy, and acts as a protective layer to extend the service life of the guide channel body.

[0042] The bottom of the straight section 501 of the guide channel 5 has two hinged blades, a front blade 12 and a rear blade 13, which can swing freely. Fixed side baffles 14 are located on the left and right sides of the bottom of the straight section 501. The front and rear sides refer to the angle adjustment directions. Both blades are connected to the side wall of the straight section 501 via their respective hinge structures, and the free ends of the blades hang naturally under gravity. The side baffles 14 can restrain the material from both sides, forming a complete material discharge channel together with the front and rear blades, preventing lateral leakage and waste of material during the final feeding stage and protecting the equipment body. A maintenance port is provided on one side wall of the guide channel 5, with a removable maintenance cover 10 connected to it for convenient subsequent maintenance.

[0043] The usage process of this utility model is described in conjunction with the accompanying drawings and technical solutions:

[0044] I. Normal Operating Status:

[0045] 1. First, based on the flowability of the crushed material, adjust the adjusting inclined support mechanism 9 on both sides to make the guide channel 5 have a reasonable tilt angle.

[0046] 2. When adjusting the guide channel 5, in order to avoid material leakage due to gaps between the bottom front and rear sides of the guide channel 5 and the center hole of the support plate 15 caused by the guide channel 5 being adjusted too large or too small, front and rear swing blades are set at the lower ends of the front and rear walls of the guide channel 5.

[0047] 3. Then, add material from the top of the guide channel 5 for crushing. At the same time, start the roller crusher.

[0048] 4. When the material is being crushed, hard stones will fly off and land on the top plate of the guide channel 5, hitting the elastic buffer layer and falling back into the crusher.

[0049] II. Abnormal Situations:

[0050] 1. If material blockage occurs in the guide channel 5, the maintenance cover 10 can be opened to clear the blockage.

[0051] 1. Install a straight cylindrical connector 4 on the upper end of the feed inlet body 2 of the existing roller crusher, add a shock-absorbing pad 3 at the middle position of the interface between the straight cylindrical connector 4 and the feed inlet body 2, and then fix the connection with screws.

[0052] 2. A support plate 15 is fixedly connected to the upper end of the straight cylindrical connector 4. A through hole is provided in the middle of the support plate 15 to facilitate the passage of materials in the guide channel 5. Supports 7 are installed on both sides of the upper end of the support plate. The supports 7 cooperate with the rotating shafts fixed on both sides of the guide channel 5 to realize that the entire guide channel 5 can rotate a certain angle around the rotating shaft.

[0053] 3. A through hole is provided in the center of the support plate 15 for material to pass through.

[0054] 4. A front swing blade 12 and a rear swing blade 13 are installed on the front and rear side walls of the bottom opening of the guide channel 5. They are connected to the side walls of the guide channel 5 by means of hinges, which can realize the swing of the front swing blade 12 and the rear swing blade 13 at a certain angle. The swing blades are vertically downward by their own weight. The purpose is to adjust the angle of the guide channel 5 while effectively preventing gaps from appearing between the bottom of the guide channel 5 and the support plate 15, which would cause the material to flow out from the gaps.

[0055] 5. Adjustment bracing mechanisms 9 are installed on both sides of the support plate 15. The lugs of the adjustment bracing mechanisms 9 are installed on the support plate 15. The flange shaft end is fixed to the side wall of the guide channel. The flange shaft end is fitted with the hole of the adjustment block 904 with clearance. The purpose is to ensure that the adjustment block 904 is always perpendicular to the threaded rod when adjusting the angle of the guide channel. The threaded rod passes through the light hole on the adjustment block 904. Adjustment nuts are fitted with the threaded rod on both sides of the light hole of the adjustment block 904 to realize the adjustment and fixation of the angle of the guide channel 5. A set of adjustment bracing is set on each side of the guide channel 5 to adjust the tilt angle of the guide channel 5.
