Abstract
Description
Technical Field
[0001] This utility model relates to the field of artificial crushing technology for large-particle solid materials, specifically to a device for artificial crushing of large-particle solid materials. Background Technology
[0002] In recent years, the coal market has been experiencing a supply shortage, with coal prices remaining high and coal quality being extremely unstable. This necessitates on-site manual sampling and crushing to monitor coal quality in real time.
[0003] Currently, commonly used coal quality truck sampling devices include full-section and point-type coal quality truck sampling machines. For large-tonnage coal transport vehicles with uneven top, middle and bottom, front, middle and rear, left, middle and right, whether it is full-section or point sampling, the number of sampling points is small, and the sampling drill bit must avoid the metal reinforcing ribs inside the truck, resulting in different degrees of difference between the quality of the coal sample and the actual coal quality.
[0004] Full-section and point-type coal quality truck samplers have the following problems:
[0005] (1) The coal batches in the whole truck are large, and the coal particle size and coal quality are objectively uneven, resulting in a deviation between the quality of the sample taken and the actual quality of the whole truck coal.
[0006] (2) During the sampling process, the particle size and appearance of the coal are not visible. It is a completely random blind sampling process, and the particle size and appearance of the coal sample cannot be determined. Utility Model Content
[0007] The problem this invention aims to solve is to provide a device that allows for the manual crushing of coal samples of different particle sizes, direct visual observation of the coal sample's color and appearance, and the establishment of an intuitive evaluation basis in conjunction with coal quality analysis data, thereby enabling on-site control of the quality of coal entering the plant. This device overcomes the technical problems existing in the current point sampling machine technology and is also portable and easy to use.
[0008] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0009] A device for manually crushing large-particle solid materials includes a steel plate with a circular hole on one side of its top surface. A steel column assembly is inserted into the hole. A steel pipe upright is provided on the top surface of the steel column assembly. A steel pipe handle is welded to the top of the steel pipe upright. The steel pipe upright includes a pipe body, and an anti-detachment ring is fitted at the bottom end of the pipe body. The steel column assembly has a central hole that matches the anti-detachment ring. A bottom cover is threaded onto the bottom surface of the steel column assembly. A vibration damping component is provided between the bottom cover and the anti-detachment ring, and the vibration damping component is located inside the central hole.
[0010] Furthermore, the steel plate includes a plate component, and a splash guard is installed on the bottom edge of the plate component.
[0011] The beneficial effect of adopting the above-mentioned further solution is that when crushing larger solid materials, it can effectively prevent the debris generated during the crushing process from splashing in all directions, avoiding injury to operators and ensuring the safety of the working environment.
[0012] Furthermore, the steel column assembly includes a first column and a second column, the top end of the first column is welded to the bottom end of the second column, and the central hole is located inside the first column and the second column.
[0013] The beneficial effect of adopting the above-mentioned further solution is that it enhances the overall strength of the steel column assembly, enabling it to withstand greater impact forces, making it less prone to damage when crushing solid materials with high hardness, and extending the service life of the device.
[0014] Furthermore, a vertical rail is installed on the inner wall of the central hole, and a slot is provided on the outer wall of the anti-detachment ring to slide against the vertical rail.
[0015] The beneficial effect of adopting the above-mentioned further solution is that it ensures the stability of the steel pipe upright during the up and down movement, so that it impacts the material vertically and improves the crushing effect, while avoiding operational errors and equipment damage caused by shaking.
[0016] Furthermore, the bottom cover includes a cover body, and a handle is embedded in the bottom surface of the cover body.
[0017] The advantage of adopting the above-mentioned further solution is that it allows operators to easily rotate the bottom cover by hand to tighten or loosen the bottom cover and the steel column assembly. The operation is simple and convenient, and the maintenance and assembly efficiency is improved.
[0018] Furthermore, the bottom surface of the cover is flush with the bottom surface of the steel plate.
[0019] The beneficial effect of adopting the above-mentioned further solution is that it makes the device more stable when placed, and the stability will not be affected by the protrusion or depression of the bottom cover, which is conducive to the operator to carry out material crushing operation on a stable basis.
[0020] Furthermore, the vibration damping component includes a damping rod, the outer wall of which is fitted with a spring, and the outer wall of the spring contacts the inner wall of the central hole.
[0021] The beneficial effect of adopting the above-mentioned further solution is that the damping rod and the spring work together to efficiently absorb and attenuate the vibration and impact forces generated during material crushing. The spring provides elastic cushioning, while the damping rod consumes vibration energy, reduces the propagation of vibration, and simultaneously reduces noise during the crushing process.
[0022] Furthermore, the steel plate, steel column assembly, steel pipe upright, and steel pipe handle are all made of stainless steel.
[0023] The beneficial effect of adopting the above-mentioned further solutions is that stainless steel has good corrosion resistance and is not easily rusted or corroded in working environments with humid or corrosive substances.
[0024] Compared with the prior art, the beneficial effects of this utility model are:
[0025] This device for manually crushing large-particle solid materials uses a vibration damping component positioned between the anti-detachment ring and the bottom cover to effectively reduce the transmission of vibrations generated during manual crushing to the operator's hands. When the steel pipe upright drives the steel column assembly to impact the material, the damping rod and spring work together to absorb and buffer the impact force, reducing operator fatigue and improving operating comfort. This allows operators to perform crushing work more continuously and efficiently. The steel pipe upright is securely connected to the steel column assembly through the anti-detachment ring, preventing it from falling off during use. The bottom cover is threaded to the steel column assembly, facilitating installation and disassembly, and enabling maintenance and replacement of the vibration damping component. This also ensures the stability of the entire device structure. When large-particle coal samples are crushed using this new device, the color and appearance of the coal sample can be directly observed, allowing for on-site assessment of the coal quality.

[0033] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a device for manually crushing large-particle solid materials, including a steel plate 100, a circular hole on one side of the top surface of the steel plate 100, a steel column assembly 200 inserted into the circular hole, a steel pipe upright 300 on the top surface of the steel column assembly 200, a steel pipe handle 400 welded to the top of the steel pipe upright 300, the steel pipe upright 300 including a pipe body 3001, an anti-detachment ring 3002 fitted at the bottom end of the pipe body 3001, a central hole 700 inside the steel column assembly 200 that matches the anti-detachment ring 3002, a bottom cover 500 threadedly connected to the bottom surface of the steel column assembly 200, a vibration damping component 600 between the bottom cover 500 and the anti-detachment ring 3002, and the vibration damping component 600 located inside the central hole 700.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] As an embodiment of this utility model, the steel plate 100 further includes a plate 1001, and a splash guard 1002 is installed on the bottom side of the plate 1001. When crushing larger solid materials, it can effectively prevent the debris generated during the crushing process from splashing in all directions, avoid causing injury to the operators, and ensure the safety of the working environment.
[0036] As an embodiment of this utility model, the steel column assembly 200 further includes a first column 2001 and a second column 2002. The top end of the first column 2001 is welded to the bottom end of the second column 2002. The central hole 700 is located inside the first column 2001 and the second column 2002, which enhances the overall strength of the steel column assembly 200, enabling it to withstand greater impact forces and making it less prone to damage when crushing solid materials with high hardness, thus extending the service life of the device.
[0037] As an embodiment of this utility model, the inner wall of the central hole 700 is further provided with a vertical rail 800, and the outer wall of the anti-detachment ring 3002 is provided with a slot 3003 that slides against the vertical rail 800, which ensures the stability of the steel pipe upright 300 during the up and down movement, so that it can vertically impact the material, improve the crushing effect, and at the same time avoid operational errors and device damage caused by shaking.

[0039] As an embodiment of this utility model, the bottom surface of the cover 5001 is flush with the bottom surface of the steel plate 100, making the device more stable when placed. The stability of the placement will not be affected by the protrusion or depression of the bottom cover 500, which is conducive to the operator to carry out material crushing operation on a stable basis.
[0040] As one embodiment of this utility model, the vibration damping component 600 further includes a damping rod 6001, with a spring 6002 fitted onto the outer wall of the damping rod 6001. The outer wall of the spring 6002 contacts the inner wall of the central hole 700. The damping rod 6001 and the spring 6002 work together to efficiently absorb and attenuate the vibration and impact forces generated during material crushing. The spring 6002 provides elastic cushioning, while the damping rod 6001 consumes vibration energy, reduces the propagation of vibration, and simultaneously reduces noise during the crushing process.
[0041] As an embodiment of this utility model, the steel plate 100, steel column assembly 200, steel pipe upright 300 and steel pipe handle 400 are all made of stainless steel. Stainless steel has good corrosion resistance and is not easy to rust or corrode in humid or corrosive working environments.
[0042] Specifically, the working principle of this device for manually crushing larger solid particles is as follows: During operation, the operator first places the larger solid particles to be crushed on the steel plate 100. The splash guard 1002 on the bottom edge of the steel plate 100 prevents debris from flying during crushing, ensuring operational safety. Then, the operator holds the steel pipe handle 400 and swings the steel pipe upright 300 up and down to drive the steel column assembly 200. The steel column assembly 200 consists of a welded first column 2001 and a second column 2002, possessing high strength and capable of withstanding significant impact. The anti-detachment ring 3002 fitted at the bottom end of the steel pipe upright 300 is located within the central hole 700 of the steel column assembly 200. Through a slot 3003 that slides into the vertical rail 800 on the inner wall of the central hole, it ensures stable movement of the steel pipe upright 300, vertically impacting the material and improving the crushing effect. When the steel column assembly 200 impacts the material, the resulting impact force is transmitted to the vibration damping component 600. The damping rod 6001 and spring 6002 in the vibration damping assembly 600 work together. The spring 6002 provides elastic cushioning, while the damping rod 6001 dissipates vibration energy, effectively reducing the transmission of vibration to the operator's hands and lowering fatigue. The bottom cover 500 is connected to the steel column assembly 200 by threads, and the handle 5002 on its bottom surface facilitates the operator's removal of the bottom cover for maintenance of the vibration damping assembly 600. All major components of the entire device are made of stainless steel, and the color and appearance of the coal sample can be directly observed, allowing for on-site assessment of the coal sample's quality.
