Description

Technical Field

[0001] This application relates to crushers, and more specifically, to hoppers that are easy to disassemble and reassemble. Background Technology

[0002] In the crushing process of the workshop production, the crusher crushes the material into powder and it falls into the hopper below. The crusher is connected to the hopper and tightened by eye bolts. There are 10 eye bolts on the four sides of the hopper. The hopper is 102 centimeters long on one side, which is quite large and weighs 50.8 kilograms. Every time the hopper is installed and dismantled, it takes 3 people to hold the hopper while tightening the eye bolts. This is not only difficult to operate, but also poses a safety hazard of injuring people or damaging the ground.

[0003] The crusher's hopper is large and heavy. The disassembly process requires three people to support the massive hopper and simultaneously tighten the four-sided lifting eye bolts, which is not only difficult to operate but also poses a safety hazard of injuring people or damaging the ground. Utility Model Content

[0004] The purpose of this application is to provide a hopper that is easy to disassemble and assemble, which can improve operational safety.

[0005] To achieve the above objectives, this utility model provides a hopper that is easy to assemble and disassemble, comprising:

[0006] A frame, which provides an installation base, and a hopper mounting position is provided on the frame;

[0007] At least two screws, one end of which is mounted on the frame;

[0008] At least two fasteners, each fastener including a threaded engagement portion and at least two levering portions, the threaded engagement portion being threadedly mounted on the screw, the levering portions being fixedly connected to the threaded engagement portion, and the spacing between the levering portions allowing the screw to pass through;

[0009] The hopper is mounted on the screw. During the forward rotation of the threaded part, the hopper is pushed closer to the hopper mounting position so that the hopper is installed at the hopper mounting position on the frame.

[0010] In an optional embodiment, the hopper includes a body and a locking block. At least two locking blocks are provided on the body, and the number of locking blocks matches the number of screws. The end of the locking block is provided with an opening slot, and the other end of the screw is installed in the opening slot of the locking block. During forward rotation, the threaded engagement part pushes the locking block to bring the hopper closer to the hopper mounting position.

[0011] In an optional embodiment, a stop is detachably provided at the opening of the slot to prevent the screw from slipping out of the slot.

[0012] In an optional embodiment, the hopper further includes reinforcing ribs, which are fixedly connected to the locking block and the body.

[0013] In an optional embodiment, the lever-assist part is provided with a connecting through hole.

[0014] In an alternative embodiment, one end of the screw is hinged to the frame.

[0015] In an optional embodiment, a hinge seat is fixedly provided on the frame, and the screw is hingedly mounted on the hinge seat.

[0016] In an optional embodiment, the screw includes a hinged end and a threaded end, the hinged end being configured as a hook-shaped structure, and the outer wall of the threaded end being provided with external threads.

[0017] In an optional implementation, the frame is a cuboid frame structure.

[0018] In an optional embodiment, the frame is provided with a material receiving port, and the location of the material receiving port corresponds to the location of the hopper.

[0019] In this application, the gaps between the lever-assist parts allow the screw to pass through, preventing interference between the lever-assist parts and the screw. When removing the hopper, the threaded mating part is rotated in the opposite direction, and the hopper gradually moves away from its mounting position and closer to the ground. As the hopper gradually lands, the screw length still has redundancy, and the threaded mating part and the hopper remain mounted on the screw, eliminating the need for personnel to lift it. This avoids the possibility of the hopper suddenly falling and injuring people or damaging the ground, greatly improving operational safety.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] Embodiments of this application provide a hopper that is easy to assemble and disassemble, including a frame 100, a screw 200, a fastener 300, and a hopper 400.

[0034] The frame 100 is used to provide an installation base. The frame 100 is provided with a hopper mounting position. The hopper mounting position is located on the frame 100 and is the position where the hopper 400 can work normally after being installed. Therefore, the hopper 400 can be used after being installed in the hopper mounting position of the frame 100. When it is necessary to remove the hopper 400, the hopper 400 needs to be removed from the frame 100 and the hopper 400 will be detached from the hopper mounting position on the frame 100.

[0035] One end of the screw 200 is mounted on the frame 100, and the other end is used to mount the hopper 400. At least two screws 200 are provided. For example, two screws 200 are provided, spaced apart on the frame 100, with the hopper 400 located between the two screws 200. In another embodiment, four screws 200 are provided, evenly distributed around the circumference of the hopper 400 on the frame 100. Of course, other numbers of screws 200 can also be provided, such as five, six, or ten.

[0036] At least two fasteners 300 are provided, and the number of fasteners 300 is matched with the number of screws 200.

[0037] The fastener 300 includes a threaded mating part 310 and at least two actuating parts 320; the threaded mating part 310 is threaded onto the screw 200, and the actuating parts 320 are fixedly connected to the threaded mating part 310, and the fixed connection is made by means such as welding or integral molding.

[0038] The hopper 400 is mounted on the screw 200; when it is necessary to install the hopper 400, such as Figure 1 As shown, rotating the lever 320 in the forward direction causes the threaded engagement part 310 to rotate in the forward direction. During the forward rotation of the threaded engagement part 310, the hopper 400 is pushed closer to the hopper mounting position, so that the hopper 400 is installed at the hopper mounting position of the frame 100. Figure 4 The image shows the hopper 400 after it has been installed.

[0039] When it is necessary to unload the hopper 400, the lever 320 is rotated in the reverse direction to cause the threaded engagement part 310 to rotate in the reverse direction. During the reverse rotation of the threaded engagement part 310 and the lever 320, the threaded engagement part 310 and the lever 320 move away from the hopper installation position along the axial direction of the screw 200. Under the action of gravity, the hopper 400 will descend synchronously with the threaded engagement part 310 and move away from the hopper installation position. The threaded engagement part 310 moves under the gradual reverse rotation of the operator, so that the hopper 400 gradually falls to the ground. Compared with the prior art, which requires multiple people to cooperate in unloading the hopper 400 and has safety risks, the hopper provided by the embodiment of this application is easy to disassemble and assemble. The length of the screw 200 can be set to be longer. When unloading, the hopper 400 can gradually approach the ground without the need for the operator to support the hopper 400, thus reducing safety hazards.

[0040] In existing technologies, eye bolts are commonly used. While the eye bolt makes tightening easy, it limits the length of the threaded rod. If the threaded rod is too long, it will press against the eye bolt as it rotates closer to the hopper's mounting position. The eye bolt cannot further push the hopper closer to the mounting position. Therefore, the threaded rod used with eye bolts is usually relatively short, and its end is far from the ground. When removing the hopper from the threaded rod, it needs to be supported by personnel while still relatively high off the ground; otherwise, it will fall to the ground. Furthermore, during the installation of the silo, operators need to lift the silo first, install it onto the threaded rod, and then turn the eye bolt on the threaded rod to install the silo into its installation position. The silo is quite heavy, which increases the burden on the operators and poses a safety hazard. Therefore, in the existing technology using eye bolts, the length of the threaded rod is limited. When the silo is removed from the threaded rod, it needs to be lifted by personnel at a high point above the ground, otherwise the silo will fall to the ground. The installation also requires personnel to lift the silo, posing a significant safety hazard.

[0041] In this application, the gaps between the lever-assisting parts 320 allow the screw 200 to pass through, eliminating concerns about interference between the screw 200 and the lever-assisting parts 320. The screw 200 can be set to a longer length. When the hopper 400 is unloaded, the threaded engagement part 310 is rotated in the reverse direction, gradually moving away from the frame 100 and the hopper mounting position. This causes the hopper 400 to gradually move away from its mounting position and closer to the ground. Even as the hopper 400 lands, the screw 200 still has a length surplus, and the threaded engagement part 310 and the hopper 400 remain mounted on the screw 200. Therefore, the hopper 400 of this application does not require manual support during unloading, and even without support, it will not suddenly fall to the ground or injure anyone, thus improving safety.

[0042] When installing the hopper 400, the hopper 400 can be installed onto the screw 200 without the operator having to lift it. Then, by rotating the threaded mating part 310, the hopper 400 is gradually moved closer to the hopper installation position, thus completing the installation and improving the convenience of loading and unloading the hopper 400.

[0043] like Figure 1 As shown, in one embodiment, the hopper 400 includes a body 410 and a locking block 420. The locking block 420 is disposed on the body 410, and at least two locking blocks 420 are disposed on the body 410. The number of locking blocks 420 matches the number of screws 200. The positions of the locking blocks 420 correspond to the positions of the screws 200.

[0044] For example, the card block 420 is fixedly mounted on the body 410 by means of welding, snap-fitting or integral molding.

[0045] like Figure 2 As shown, the end of the locking block 420 is provided with an opening groove 450, and the other end of the screw 200 is installed in the opening groove 450 of the locking block 420. During the forward rotation of the threaded mating part 310, the locking block 420 is pushed so that the hopper 400 moves closer to the hopper installation position.

[0046] The slot 450 at the end of the locking block 420 allows the screw 200 to be easily installed onto the locking block 420. During installation, the operator does not need to use complicated tools or perform cumbersome operations; they only need to align the screw 200 with the slot 450 and insert it. This simplifies the installation process, reduces the difficulty of installation, and even non-professionals can easily complete the installation operation.

[0047] like Figure 2 As shown, in one embodiment, a stop 440 is detachably provided at the opening of the opening slot 450, and the stop 440 stops the screw 200 from sliding out of the opening slot 450.

[0048] For example, the locking block 420 has an assembly through hole at the opening slot 450, and the stop member 440 is a bolt rod that passes through the assembly through hole of the locking block 420, thereby preventing the stop member 440 from slipping out of the opening slot 450. In other embodiments, a T-slot is provided on the inner wall of the opening slot 450 of the locking block 420, and the stop member 440 is a T-block that engages in the T-slot, thereby preventing the stop member 440 from slipping out of the opening slot 450.

[0049] During the operation of the silo, the hopper 400 is subjected to various forces, such as the impact force of materials and the force generated by equipment vibration. Without the stopper 440, the screw 200 may wobble or even slip out of the opening slot 450, causing the hopper 400 to be unstable or fall off, leading to a safety accident. The presence of the stopper 440 provides a reliable limit for the screw 200, ensuring the stability of the connection between the screw 200 and the locking block 420, thereby ensuring the safe operation of the entire silo structure.

[0050] The stop 440 is designed to be detachable, such as by inserting a bolt through the mounting hole or by engaging a T-block in a T-slot. This allows operators to easily install or remove the stop 440 as needed when installing and disassembling the hopper 400. When installing the hopper 400, the screw 200 is first placed into the opening slot 450, and then the stop 440 is installed to complete the initial fixing. During disassembly, removing the stop 440 allows the screw 200 to be removed from the opening slot 450, simplifying the operation and improving work efficiency.

[0051] like Figure 2 As shown, in one embodiment, the hopper 400 further includes a reinforcing rib 430, which is fixedly connected to the locking block 420 and the body 410.

[0052] As a key component connecting the screw 200 and the hopper 400 body 410, the locking block 420 bears significant forces during the installation, use, and disassembly of the hopper 400. The reinforcing rib 430 securely connects the locking block 420 and the body 410, effectively dispersing the forces on the locking block 420 and transferring localized stress to the hopper 400 body 410. This prevents the locking block 420 from deforming or breaking due to concentrated stress, thus greatly enhancing the connection strength between the locking block 420 and the body 410 and ensuring that the locking block 420 can be stably and reliably fixed to the hopper 400.

[0053] When materials are loaded into the hopper 400, the weight of the materials will exert a significant pressure on the hopper 400. The reinforcing rib 430 enhances the structural strength of the hopper 400, enabling it to withstand heavier materials without damage.

[0054] like Figure 2 As shown, in one embodiment, the lever assist part 320 is provided with a connecting through hole 330.

[0055] The lever-assisted unit 320 reduces the force required to rotate the threaded mating part 310 using the lever principle. In mechanical transmission, when the lever-assisted unit 320 is used to rotate the threaded mating part 310, according to the lever principle, the effort arm is greater than the resistance arm. The operator can generate a large torque on the threaded mating part 310 by applying a small force to the lever-assisted unit 320, thus easily rotating the threaded mating part 310. This significantly reduces the operational difficulty for threaded mating parts 310 that require large torque to rotate, allowing operators to complete rotation operations more easily and quickly, thereby improving work efficiency.

[0056] A connecting through hole 330 is provided on the lever-assist unit 320, facilitating the insertion of tools. When it is necessary to rotate the lever-assist unit 320, the operator can select an appropriate tool, such as a pry bar or wrench, and insert it into the connecting through hole 330. Inserting the tool increases the length of the power arm, further amplifying the leverage effect and making it easier to rotate the lever-assist unit 320. Moreover, operating with a tool is more stable and precise than operating by hand, allowing for better control of the rotation angle and force, thus improving the quality and reliability of the operation.

[0057] In one embodiment, one end of the screw 200 is hinged to the frame 100, making the screw 200 easy to swing.

[0058] Because the hopper 400 is quite heavy, moving it to the fixed position of the screw 200 for installation using traditional methods would require a significant amount of manpower and resources, and the operation would be cumbersome and difficult. However, by hinged one end of the screw 200 to the frame 100, allowing it to swing, installation can be completed simply by swinging the screw 200 to move it to the appropriate position to connect with the hopper 400. This eliminates the need to move the heavy hopper 400, greatly reducing the installation difficulty. Even a single person can easily complete the initial connection work.

[0059] Moving the hopper 400 is a time-consuming and labor-intensive process, especially when the hopper 400 is large and heavy. It may require multiple people working together and take a long time to accurately place it in the position of the screw 200. However, by connecting the hopper 400 to the screw 200 through a swing mechanism, the number of hopper 400 moving steps is reduced, which can significantly shorten the installation time, improve the overall installation efficiency, and enable the equipment to be put into use more quickly.

[0060] To achieve the hinged mounting of screw 200 onto frame 100, such as Figure 3 As shown, in one embodiment, a hinge seat 110 is fixedly provided on the frame 100, and the screw 200 is hingedly mounted on the hinge seat 110.

[0061] For example, the hinge seat 110 is fixedly mounted on the frame 100 by means of welding, snap-fitting or bolting.

[0062] like Figure 1 As shown, in one embodiment, the screw 200 includes a hinged end 210 and a threaded end 220; as Figure 3 As shown, the hinge end 210 is configured as a hook-shaped structure, and is hinged to the hinge seat 110 through the hook-shaped structure; as Figure 2 As shown, the outer wall of the threaded end 220 is provided with an external thread.

[0063] The hinge end 210 is configured as a hook-shaped structure and hinged to the hinge seat 110. The hook can tightly hook onto the hinge seat 110. When the screw 200 is subjected to forces in various directions, this hook structure can greatly reduce the risk of the screw 200 dislodging from the hinge seat 110, ensuring the stability and reliability of the connection between the screw 200 and the hinge seat 110, and making the entire mechanical structure safer during operation.

[0064] The hook-shaped structure can better distribute stress at the connection point. When the screw 200 is subjected to external force, the stress will not concentrate in a small area, but will be evenly distributed along the curve of the hook, reducing the possibility of damage or breakage of the connection point due to stress concentration and extending the service life of the screw 200.

[0065] like Figure 1 As shown, in one embodiment, the frame 100 is a rectangular frame structure, which reduces obstructions and facilitates operation by the operator.

[0066] The rectangular frame structure itself has good mechanical properties, and its frame structure can evenly distribute the weight and external forces borne by the equipment to each supporting component. After reducing unnecessary obstructions, operators will not be disturbed or hindered by too many frame 100 components when operating around the equipment, and can operate the threaded mating part 310 and the lever assist part 320 more conveniently.

[0067] like Figure 1 As shown, in one embodiment, the frame 100 is provided with a material receiving port 120, the position of which corresponds to the position of the hopper 400, and external materials can enter the body 410 of the hopper 400 from the material receiving port 120.

[0068] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
