Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation technology, specifically to a coal truck hopper cleaning device. Background Technology

[0002] As a crucial energy source for modern industrial systems, coal transportation process optimization plays a vital role in ensuring the efficient operation of the energy supply chain. In the coal logistics system, traditional transportation methods primarily rely on dump trucks or continuous belt conveyor systems to transfer raw coal from mining sites to coal storage bases or other terminals. As core equipment in the transportation chain, the cleanliness and maintenance of coal truck hoppers not only affect transportation efficiency but also directly impact coal quality and the production environment for subsequent processing stages.

[0003] Currently, the commonly used coal truck hopper cleaning technologies in the industry mainly include three categories: manual shoveling and cleaning, hydraulic tipping for forced unloading, and high-pressure water jet washing. While these conventional methods can achieve basic cleaning functions, they have revealed significant limitations in practical applications. First, manual cleaning is inefficient, labor-intensive, and poses safety hazards. Second, hydraulic tipping struggles to completely remove strongly adhered coal slag, especially in the complex corners and edges of the truck hopper where residue is severe. Third, while high-pressure water washing can improve cleanliness, it suffers from high water consumption and high costs for coal slime wastewater treatment. In particular, under cold climate conditions, the freezing and sticking of water-containing coal slag further exacerbates the cleaning difficulty.

[0004] Therefore, there is an urgent need for a coal truck hopper cleaning device to solve the above-mentioned technical problems. Utility Model Content

The elastic element is sleeved on the body and located within the through groove. One end of the elastic element is fixedly connected to the head, and the other end is fixedly connected to the positioning seat. The elastic element has a tendency to drive the body into the limiting hole.

[0010] In one embodiment, the diameter of the column head is larger than the diameter of the through groove.

[0011] In one embodiment, the extension mechanism further includes a connecting assembly comprising a connecting plate and a connector, the connecting plate being fixed to the end of the extension plate away from the arm body, and the connecting plate being connected to an external extension rod via the connector.

[0012] In one embodiment, the cleaning mechanism further includes a mounting assembly, which includes a mounting rod and a mounting base.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Firstly, see Figures 1-4 An embodiment of this application provides a coal truck hopper cleaning device including an arm 1, a cleaning mechanism, and a protection mechanism. The arm 1 has a fixed groove in the middle and a first through hole communicating with the fixed groove at one end along a first direction. The cleaning mechanism includes a pushing component, a rotating component, and a cutter 3. The pushing component includes a first driving member, which is fixedly installed in the fixed groove and has its output end passing through the first through hole. The rotating component includes a second driving member, which is fixed to the output end of the first driving member. The first driving member can drive the second driving member to move along the length direction of the arm 1 and is used to drive the cutter 3 to rotate. The protection mechanism includes two protective arms 8, which are fixed to the side of the arm 1 near the cutter 3 and are symmetrically arranged on both sides of the cutter 3. Each protective arm 8 has a working groove for the cutter 3 to pass through.

[0029] The coal truck hopper cleaning device provided in this embodiment uses a fixed groove and a first through hole to provide installation space for the first driving component, thereby ensuring that the first driving component can accurately control the feeding motion of the cutter 3 and effectively adapt to the cleaning needs of different depths of the truck hopper. In addition, by setting a second driving component, the first driving component and the second driving component work together to realize the composite motion of the rotation and feeding of the cutter 3, which greatly enhances the ability to break up frozen coal slag and wet coal slime, thereby solving the problems of low efficiency of traditional manual cleaning and high resource consumption of high-pressure water washing. It is particularly suitable for the rapid processing of frozen coal slag in low-temperature environments. Furthermore, by setting symmetrically arranged protective arms 8, it can prevent the cutter 3 from rigidly colliding with the inner wall of the truck hopper, thus protecting the cutter 3 and avoiding damage to the truck hopper.

[0030] In this embodiment, the cutting tool 3 adopts a disc-shaped structure design.

[0031] In this embodiment, the first driving component is a push rod motor 2, and the second driving component is a rotary motor.

[0032] In this embodiment, the protective arm 8 has an L-shaped rod structure.

[0033] By setting the protective arm 8 into an L-shaped rod structure, it not only provides ample working space for the rotating cutter 3, but also effectively blocks splashing coal slag, protecting operational safety. The protective arm 8 forms a three-dimensional protective zone within a limited space, and can prevent the cutter 3 from shifting laterally and colliding with the inner wall of the truck bed, significantly improving the service life of the device.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, an extension mechanism is also included. The extension mechanism includes an extension plate 5 and a positioning component 6. A sliding cavity is provided at the end of the arm body 1 away from the cutter 3. The extension plate 5 is slidably disposed in the sliding cavity. The positioning component 6 is fixed to the arm body 1 and is used to fix the relative position of the extension plate 5 and the arm body 1.

[0035] By employing a sliding cavity and extension plate 5 in combination, the length of the boom 1 can be flexibly adjusted, allowing the operator to freely adjust the cleaning range according to the depth of the bucket. This effectively solves the problem that traditional fixed-length cleaning tools cannot reach the far-end blind spots of the bucket. In addition, the positioning component 6 ensures that the extension plate 5 is stably locked at any extension position, avoiding accidental displacement caused by vibration or force during operation. This not only ensures cleaning accuracy but also improves operational safety and significantly enhances work efficiency.

[0036] like Figure 1 and Figure 2As shown, in some embodiments, the extension mechanism includes at least two positioning plates 7, which are respectively fixed on both sides of the extension plate 5 along the width direction of the arm body 1. At least two sliding grooves are provided on both sides of the sliding cavity along the width direction of the arm body 1. The positioning plates 7 are arranged in a one-to-one correspondence with the sliding grooves. Each positioning plate 7 is located in the sliding groove corresponding to it, and each positioning plate 7 is slidably connected to the sliding groove corresponding to it.

[0037] By symmetrically arranging the positioning plates 7 on both sides of the extension plate 5, and forming a double guiding structure with the corresponding sliding grooves in the sliding cavity, the lateral offset and torsion of the extension plate 5 during the extension and retraction process can be effectively limited, ensuring that the extension mechanism always moves smoothly along the predetermined trajectory. This not only enhances the bending stiffness of the overall structure, allowing the extension plate 5 to maintain sufficient stability when fully extended, thus being able to withstand the reaction force of the cleaning operation, but also greatly reduces the wear between components, thereby extending the service life of the device.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the positioning component 6 includes a positioning seat 601 and a positioning member 602. The positioning seat 601 is fixed to the top of the arm body 1. The positioning seat 601 has a through groove. The arm body 1 has a second through hole that connects the through groove and the sliding cavity. The extension plate 5 has a plurality of limiting holes spaced apart along the length direction of the arm body 1. The positioning member 602 can pass through the through groove, the second through hole and the limiting hole in sequence to fix the relative position of the extension plate 5 and the arm body 1.

[0039] By setting the positioning seat 601 as a base and installing it on the top of the arm body 1, and forming a precisely aligned guide channel between the through groove of the positioning seat 601 and the second through hole of the arm body 1, it is ensured that the positioning member 602 can be smoothly inserted into any limiting hole of the extension plate 5. In addition, the multiple limiting holes arranged at intervals on the extension plate 5 provide operators with multiple adjustment options, allowing operators to flexibly select the extension length according to actual cleaning needs.

[0040] In addition, when the positioning component 602 passes through the through slot, the second through hole and the selected limiting hole in sequence, a three-point lock is formed, which effectively resists the longitudinal and lateral loads generated during the cleaning operation, prevents the extension plate 5 from retracting or shaking, ensures the stability of the working state, and significantly improves the device's adaptability to different depths of the truck bed and the safety of the operation.

[0041] like Figure 1 and Figure 2As shown, in some embodiments, the positioning component 6 further includes an elastic element 603. The positioning element 602 includes a column head and a column body. The column head is fixed to the end of the column body away from the extension plate 5. The elastic element 603 is sleeved on the outside of the column body and is located in the through groove. One end of the elastic element 603 is fixedly connected to the column head, and the other end of the elastic element 603 is fixedly connected to the positioning seat 601. The elastic element 603 has the tendency to drive the column body into the limiting hole.

[0042] The continuous elastic force generated by the elastic element 603 within the through groove pushes the column into the limiting hole of the extension plate 5, forming a stable mechanical lock. This effectively prevents accidental displacement during operation. Furthermore, the column head allows for easy one-handed unlocking by the operator. The elasticity of the elastic element 603 ensures that the column immediately returns to its original position after release, enabling rapid length adjustment. This simplifies the operation process and avoids the problems of traditional threaded fastening or easily lost pins, significantly improving the convenience and reliability of the device's adjustment. In addition, the elastic element 603 also has an elastic buffering effect, absorbing operational vibrations, protecting the positioning component 6 from impact damage, and extending the device's service life.

[0043] like Figure 1 and Figure 2 As shown, in some embodiments, the diameter of the column head is larger than the diameter of the through groove.

[0044] By setting the diameter of the column head of the positioning component 6 to be larger than the diameter of the through groove, a reliable limiting structure can be formed, ensuring that the column head is indeed located outside the through groove, and the elastic element 603 always remains in the normal working position within the through groove. This interference fit prevents the column from completely entering the through groove, avoids the positioning element 602 from being unable to unlock, and maintains the stability of the elastic preload.

[0045] like Figure 1 and Figure 4 As shown, in some embodiments, the extension mechanism further includes a connecting assembly, which includes a connecting plate 9 and a connector. The connecting plate 9 is fixed to the end of the extension plate 5 away from the arm body 1, and the connecting plate 9 is connected to an external extension rod through the connector.

[0046] By incorporating connectors, external extension rods of varying lengths can be quickly installed, allowing for flexible expansion of the cleaning range based on actual operational needs. This achieves both a compact basic structure and the ability to handle special working conditions such as ultra-deep truck beds, significantly improving the equipment's versatility and efficiency. Furthermore, the secure fit between the connectors and the connecting plate 9 ensures reliable power transmission, preventing loosening or misalignment between the extension mechanism and the extension rod, thus maintaining stable cleaning performance even at maximum cleaning range.

[0047] like Figure 1 and Figure 3As shown, in some embodiments, the cleaning mechanism further includes a mounting assembly, which includes a mounting rod 11 and a mounting base 12. One end of the mounting rod 11 is fixed to the output end of the first drive member, and the other end of the mounting rod 11 is provided with a snap-fit ​​groove. The mounting base 12 is provided with a snap-fit ​​member that snaps into the snap-fit ​​groove. The second drive member is fixed to the mounting base 12, and the mounting rod 11 is provided with a working groove for the tool 3 to rotate.

[0048] By setting up the mounting rod 11 and the mounting base 12, it is possible to ensure that the first driving component stably drives the second driving component to move, and it is also convenient to replace the cutter 3, which significantly improves the maintenance convenience of the device. When the cutter 3 or the driving component needs to be repaired, it is not necessary to disassemble the entire cleaning mechanism, which greatly improves maintenance efficiency. In addition, the working groove opened on the mounting rod 11 provides sufficient space for the rotation of the cutter 3, which can provide protection for the cutter 3.

[0049] like Figure 1 and Figure 4 As shown, in some embodiments, a handle 4 is also included. The handle 4 is located at the end of the arm 1 away from the cutter 3, and the handle 4 is fixedly connected to both sides of the arm 1 along the width direction. The handle 4 adopts an I-shaped plate structure, and a gripping groove 10 is provided on the handle 4.

[0050] By fixing grips on both sides of the arm body 1, the operator's hands can be subjected to more even force, effectively dispersing hand fatigue during long-term work, enabling the operator to accurately control the cleaning angle and force to maintain stable operation, and greatly improving work safety and efficiency.

[0051] In this embodiment, the handle 4 adopts an I-shaped plate structure. The I-shaped cross section can greatly reduce the weight of the handle 4 while ensuring structural strength. In addition, the grip groove 10 is curved, which can perfectly fit the curvature of the palm, so that the operator can grip it firmly and prevent slipping during operation.

[0052] In some embodiments, a sponge pad is also provided inside the grip groove 10 to improve operator comfort.

[0053] like Figure 1 As shown, in some embodiments, the cleaning mechanism includes a scraper fixed to the protective arm 8 and located in the working groove, the scraper being able to clean the blade 3.

[0054] By fixing a scraper in the working groove of the protective arm 8, the scraper can automatically scrape off the coal slag adhering to the surface of the cutter 3 during the operation of the cutter 3, effectively preventing the accumulation of coal sludge from affecting the cutting performance of the cutter 3. Thus, the cutter 3 can maintain its optimal working condition without interrupting the operation, significantly reducing the frequency of manual cleaning, and enabling the device to maintain a stable cleaning effect under complex working conditions, especially in the work of handling easily adhering materials such as high-viscosity wet coal or frozen coal slag.

[0055] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
