Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining transport hopper technology, specifically a transport hopper for mining machines. Background Technology
[0002] Mining machine transport hoppers are an important component of mining equipment, mainly used to collect, load, and transport materials such as ore during the mining process. Typically, they are used to collect and guide the ore to slide down and fall to the conveyor below, and then transport it out through the mine shaft, facilitating collection and transportation, and improving the overall mining efficiency.
[0003] In the field of mining transport hoppers, existing mining machine transport hoppers use adhesive pads inside to prevent excessive impact. However, this method is not effective in overall impact protection and noise reduction. Large impacts from ore can cause local deformation of the hopper, resulting in dents, bulges, or bends in the hopper body. This not only affects the hopper's volume and material loading efficiency but may also lead to poor unloading, affecting the normal operation of mining. Utility Model Content
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] Given that the existing technologies mentioned above or in the prior art are not effective in overall impact protection and noise reduction, the impact of large-scale ore may cause local deformation of the hopper, resulting in dents, bulges or bends in the hopper body. This will not only affect the hopper volume and material loading efficiency, but may also lead to poor unloading and affect the normal operation of mining.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A transport hopper for a mining machine, characterized in that it comprises:
[0008] The conveying equipment body has a guide shell fixedly installed on one side of the top of the conveying equipment body, and a storage shell fixedly installed on the top of the guide shell. A rubber pad is fixedly installed inside the storage shell, and a protective mechanism is provided on one side of the rubber pad.
[0009] The protective mechanism includes a support rod, which is fixedly installed inside the storage shell, and a rotating block is rotatably connected to the outer wall of the support rod. A first anti-collision pad is fixedly installed on the top of the rotating block.
[0010] As a further improvement of this utility model: a fixing sleeve is embedded in one side of the inner side of the storage shell, and a protruding rod extends out from the inside of the fixing sleeve.
[0011] As a further embodiment of this utility model: a first spring is fixedly installed at one end of the protruding rod that enters the fixed sleeve, and a limit ring is fixedly installed on the outer wall of the end of the protruding rod that enters the fixed sleeve.
[0012] As a further improvement of this utility model: a connecting frame is fixedly installed at the front end of the protruding rod, and an abutment roller is rotatably connected to the outer wall of the connecting frame.
[0013] As a further improvement of this utility model: a discharge port is provided on one side of the lower interior of the storage shell, and an abutment mechanism is provided on one side of the discharge port.
[0014] As a further embodiment of this utility model: the abutting mechanism includes a rotating cylinder, which is rotatably connected to one side of the abutting roller on the inner wall of the storage shell, and a second spring is fixedly installed on the outer wall of the rotating cylinder, with a rubber plate fixedly installed at one end of the second spring.
[0015] As a further improvement of this utility model: a sliding rod is fixedly installed inside the second spring on the outer wall of the rubber plate, and a limit block is fixedly installed at one end of the sliding rod that passes through the rotating cylinder.
[0016] As a further improvement of this utility model: a fixing plate is fixedly installed above the discharge port inside the storage shell, and a second anti-collision pad is fixedly installed on the outer wall of the fixing plate.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This utility model, through the design of support rod, rotating block, fixed sleeve, through rod, first spring, connecting frame and abutment roller, realizes the bearing of falling ore and plays a certain energy dissipation and buffering effect, avoiding the situation where the ore falls directly and collides with the guide shell and the receiving shell, resulting in large noise and possibly causing deformation or damage to the guide shell and the receiving shell.
[0019] 2. The present invention, through the design of the first anti-collision pad and the limiting ring, can prevent the through rod from falling off when the rotating block resets after the ore impact, and together with the first anti-collision pad, it provides a certain degree of protection for the rotating block.
[0020] 3. This utility model, through the design of the rotating cylinder, the second spring, and the rubber plate, achieves a further energy dissipation and buffering effect on the falling ore, avoiding excessive impact during the conveying process and preventing damage to the main body of the conveying equipment, the guide shell, and the receiving shell.
[0021] 4. The design of the sliding rod and the limiting block of this utility model can prevent the second spring from twisting when it is bent under force, which would affect the stability of the rubber plate. The limiting block also prevents the sliding rod from disengaging from the rotating cylinder, thereby improving the stability of the rubber plate under force.
[0022] 5. This utility model, through the design of a fixing plate and a second anti-collision pad, can guide the falling ore to the final stage, slowing down the impact layer by layer, and ultimately preventing direct collision with the main body of the conveying equipment and thus avoiding damage.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0032] Example 1
[0033] Please see Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides a transport hopper for a mining machine, including: a conveying equipment body 1, a guide shell 2 fixedly installed on one side of the top of the conveying equipment body 1, a storage shell 3 fixedly installed on the top of the guide shell 2, a rubber pad 4 fixedly installed inside the storage shell 3, and a protective mechanism 5 provided on one side of the rubber pad 4.
[0034] The protective mechanism 5 includes a support rod 501, which is fixedly installed inside the storage shell 3. A rotating block 502 is rotatably connected to the outer wall of the support rod 501, and a first anti-collision pad 503 is fixedly installed on the top of the rotating block 502.
[0035] Specifically, a fixing sleeve 504 is embedded in one side of the inside of the storage shell 3, and a protruding rod 505 extends out of the inside of the fixing sleeve 504.
[0036] Furthermore, by fixing the sleeve 504, the through rod 505 can maintain stability during sliding to avoid deviation or wobbling.
[0037] Specifically, a first spring 506 is fixedly installed at one end of the protruding rod 505 that enters the fixed sleeve 504, and a limit ring 507 is fixedly installed on the outer wall of the end of the protruding rod 505 that enters the fixed sleeve 504.
[0038] Furthermore, the limiting ring 507 can prevent the through rod 505 from excessively disengaging from the fixed sleeve 504 due to the push of the first spring 506 during the sliding process.
[0039] Specifically, a connecting frame 508 is fixedly installed at the front end of the through rod 505, and an abutment roller 509 is rotatably connected to the outer wall of the connecting frame 508.
[0040] Furthermore, the abutment roller 509, which is rotatably connected by the connecting frame 508, slides against the rotating block 502 to prevent excessive friction from causing vibration or noise when the rotating block 502 rotates and shifts, thus preventing it from failing to achieve the anti-collision effect.
[0041] In use, the ore is first transported to the receiving shell 3 by the mining machine, and then guided by the guide shell 2 before falling onto the main body 1 of the conveying equipment and being transported to the outside. The rubber pad 4 bonded inside the receiving shell 3 initially provides anti-collision, and at the same time, the rotating block 502, which is rotatably connected to the support rod 501, rotates when impacted or pressured by the ore, and can slide against the outer wall of the contact roller 509. With the help of the connecting frame 508, the through rod 505 slides along the fixed sleeve 504 and compresses the first spring 506 to achieve an energy dissipation effect. With the help of the first anti-collision pad 503 made of rubber bonded to the rotating block 502, it can provide a certain anti-collision effect. Under the guidance of the rotating block 502, the ore falls into the guide shell 2. After the ore falls, the first spring 506 elastically pushes the rotating block 502 back to its original position, and with the help of the limit ring 507, the through rod 505 is prevented from detaching.
[0042] In summary, when the ore enters the receiving shell 3 and impacts the rotating block 502, the elastic contraction of the first spring 506, combined with the rotation of the rotating block 502, can reduce the impact force to a certain extent. At the same time, the first anti-collision pad 503 prevents the rotating block 502 from being bumped or scratched. The rotating block 502 can play a buffering role, thereby preventing the ore from directly impacting the receiving shell 3, which would cause excessive noise or even cause the guide shell 2 and the receiving shell 3 to be deformed and damaged by the impact.
[0043] Example 2
[0044] Please see Figure 3 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for a transport hopper for a mining machine.
[0045] Specifically, a discharge port 6 is provided on one side of the lower part of the inner side of the storage shell 3, and an abutment mechanism 7 is provided on one side of the discharge port 6.
[0046] Furthermore, the discharge port 6 facilitates the transport of ore that falls onto the main body 1 of the conveying equipment, and allows it to pass through the receiving shell 3.
[0047] Specifically, the abutment mechanism 7 includes a rotating cylinder 701, which is rotatably connected to one side of the abutment roller 509 on the inner wall of the storage shell 3. A second spring 702 is fixedly installed on the outer wall of the rotating cylinder 701, and a rubber plate 703 is fixedly installed on one end of the second spring 702.
[0048] Furthermore, the ore entering the guide shell 2 collides with the rubber plate 703, and with the elastic contraction of the second spring 702 and the rotation of the rotating cylinder 701, the energy dissipation effect can be greatly improved, avoiding excessive impact.
[0049] Specifically, a sliding rod 704 is fixedly installed inside the second spring 702 on the outer wall of the rubber plate 703, and a limit block 705 is fixedly installed at one end of the sliding rod 704 that passes through the rotating cylinder 701.
[0050] Furthermore, the sliding rod 704 extends into the interior of the rotating cylinder 701. Through the cooperation of the sliding rod 704 and the limiting block 705, it can support the second spring 702 and prevent the rubber plate 703 from shifting due to twisting. At the same time, the limiting block 705 engages with the rotating cylinder 701 to prevent the sliding rod 704 from falling off.
[0051] Specifically, a fixing plate 706 is fixedly installed above the discharge port 6 inside the storage shell 3, and a second anti-collision pad 707 is fixedly installed on the outer wall of the fixing plate 706.
[0052] Furthermore, through the cooperation of the inclined fixing plate 706 and the second anti-collision pad 707, the falling ore is supported and guided again to avoid direct impact with the storage shell 3.
[0053] In use, the ore entering the guide shell 2 directly impacts the rubber plate 703. Combined with the elastic contraction of the second spring 702 and the rotation of the rotating cylinder 701, it can further achieve the energy dissipation and buffering effect. At the same time, the sliding rod 704 prevents the second spring 702 from being overly twisted, and the limiting block 705 prevents the sliding rod 704 from sliding off the rotating cylinder 701. The fixing plate 706 and the second anti-collision pad 707 then bear the ore that has been slowed down by the rubber plate 703, preventing it from colliding with the guide shell 2. After that, it is directly guided to the main body of the conveying equipment 1 and then conveyed out through the discharge port 6.
[0054] In summary, when subjected to the impact of falling ore, the rotation of the rotating cylinder 701, combined with the elastic support of the rubber plate 703 by the second spring 702, can achieve an energy dissipation and buffering effect, further reducing the impact force during ore conveying, avoiding collisions with the main body 1 and guide shell 2 that could cause deformation, and in conjunction with the fixing plate 706 and the second anti-collision pad 707, it can again bear the ore during the conveying process, preventing it from colliding with the guide shell 2 and guiding it to slide down to the main body 1 of the conveying equipment for conveying.
