Description

Technical Field

[0001] This utility model relates to the technical field of water-soaked mud filling equipment, and in particular to a foot-operated water-soaked mud filling device. Background Technology

[0002] Water-filled mud is a specialized product used in coal mines for dust suppression and prevention of electrical sparks during blasting. It is made by injecting water into a mud bag and sealing the opening. After the explosive detonates, the water in the mud forms a water curtain under the impact of the explosive gases, reducing the detonation temperature and shortening the duration of the explosion flame. This reduces the likelihood of igniting gas and coal dust, promoting safer production. It also helps suppress dust and absorb harmful gases from the blasting fumes, improving working conditions. The traditional method of water injection involves placing the mud bag over a water needle connected to a water pipe, with workers manually injecting water. This method is inconvenient, reduces efficiency, and consequently lowers the production efficiency of the mud, thus reducing coal mining efficiency.

[0003] To address the aforementioned issues, foot-operated filling structures have emerged, such as patent CN 209416188U, which discloses a water-filling device for sludge. This device includes an operating platform, a foot-operated flushing valve, a water injection pipe, and a water outlet pipe. A foot-operated flushing valve with its outlet facing upwards is vertically fixed below the operating platform. The inlet of the foot-operated flushing valve is connected to the outlet of the water injection pipe, and the outlet of the foot-operated flushing valve is connected to the outlet pipe. The outlet of the outlet pipe extends above the operating platform and is fitted with a water needle with its outlet facing downwards. A fixed cylinder is slidably mounted on the top of the operating platform below the water needle, and the sludge is placed inside the fixed cylinder. This foot-operated filling structure effectively improves filling efficiency.

[0004] However, the operating platform used to receive the sludge and the overall filling structure are separate units, and they are generally large in size. They need to be reassembled during use and disassembled when not in use, which makes installation and disassembly inconvenient and increases the cost of use. In addition, the separate structure also makes it inconvenient to carry during transportation. Utility Model Content

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Please see Figures 1-2 A foot-operated sludge filling device includes a water injection pipe 200 and a filling body 100. The filling body 100 includes a foot-operated water valve mechanism 300 and a water outlet pipe 110 connected to each other. The water injection pipe 200 is connected to the foot-operated water valve mechanism 300. The foot-operated water valve mechanism 300 is used to control the connection or blockage of the water injection pipe 200 and the water outlet pipe 110. A water needle 111 is provided at the end of the water outlet pipe 110 away from the foot-operated water valve mechanism 300. An operating plate 400 is hinged to the filling body 100. The operating plate 400 is provided with a working end face 410 for receiving sludge. The operating plate 400 can rotate relative to the filling body 100 around the hinge axis to have at least a working position. In the working position, the working end face 410 is arranged opposite to the water needle 111.

[0026] In this embodiment, as Figure 1As shown, the filling body 100 is arranged vertically. A foot-operated water valve mechanism 300 is located at the bottom of the filling body 100. One end of the water injection pipe 200 is connected to the foot-operated water valve mechanism 300. The water outlet pipe 110 is arranged vertically inside the filling body 100, and its bottom end is connected to the foot-operated water valve mechanism 300. The upper end of the water outlet pipe 110 forms an arc-shaped bend, causing the upper opening of the water outlet pipe 110 to face downwards vertically. A water needle 111 is installed at this opening, also arranged vertically with its opening facing downwards. The foot-operated water valve mechanism 300 is installed vertically at the bottom. The foot-operated water valve mechanism 300 can control the connection or disconnection of the water injection pipe 200 and the water outlet pipe 110 by the operator's foot pedaling or releasing action. Furthermore, the filling body 100... An operating plate 400 is hinged between the foot-operated water valve mechanism 300 and the water needle 111. One end of the operating plate 400 is hinged to the filling body 100. The operating plate 400 can rotate vertically relative to the filling body 100. In the initial state, the operating plate 400 can be rotated to the lowest position. In this position, the operating plate 400 is placed vertically. During operation, the operating plate 400 can be rotated upward to the working position. In this position, the operating plate 400 is set horizontally, and its upper end face is the working end face 410, so that the water needle 111 is directly opposite the operating plate 400 and the working end face 410. Then, the water-filled mud to be injected is placed on the working end face 410, so that the water-filled mud to be injected corresponds to the operating plate 400.

[0027] In actual operation, the water injection pipe 200 is connected to the foot-operated water valve mechanism 300. The operating plate 400 is rotated upward relative to the filling body 100 to the working position, i.e., the operating plate 400 is in a horizontal state, so that the water needle 111 corresponds to the working end face 410 of the operating plate 400. The mud to be injected is placed on the working end face 410 of the operating plate 400, so that the water needle 111 can be inserted into the mud. Then, the operator steps on the foot-operated water valve mechanism 300. The system is opened, connecting the water inlet pipe 200 and the outlet pipe 110. Water flows within the outlet pipe 110 and is injected into the sludge through the water needle 111 at one end of the outlet pipe 110. After water injection is complete, the operator releases the foot pedal water valve mechanism 300, blocking the water supply by disconnecting the water inlet pipe 200 and the outlet pipe 110. The sludge is then removed from the operating plate 400, replaced with new sludge, and the above steps are repeated to complete the water injection. After all water injection is complete, the operating plate 400 is rotated downwards relative to the filling body 100 back to its initial position, i.e., the operating plate 400 is in a vertical position, completing the recycling process.

[0028] In the above structure, a foot-operated water valve mechanism 300 connects the water injection pipe 200 and the water outlet pipe 110. The flow of water is controlled by foot pedal movement. Compared with the traditional manual squeezing water injection method, workers do not need to continuously squeeze manually, which greatly reduces the operation time, increases the filling quantity per unit time, significantly improves filling efficiency, and avoids the disadvantages of water accumulation at the construction site and easy splashing of workers' clothes. In addition, by hinged the operating plate 400 to the filling body 100, the operating plate 400 and the filling body 100 are integrated, avoiding the problem of loading and unloading during work, improving the convenience of use and work efficiency. The hinged integrated structure is also easy to store and transport, effectively avoiding the problem of loss of disassembled structural components.

[0029] In the specific structure of the filling body 100, the filling body 100 includes a fixed rod 120, a water outlet pipe 110 is placed inside the fixed rod 120, one end of the operating plate 400 is provided with a first hinge part 420, and the side end of the fixed rod 120 is provided with a second hinge part 121. The first hinge part 420 and the second hinge part 121 are hinged together.

[0030] In this embodiment, as Figure 1 , Figure 2 As shown, the fixed rod 120 is a columnar mechanism, arranged vertically. A water outlet pipe 110 is provided inside the fixed rod 120. A second hinge portion 121 is provided on the side of the fixed rod 120. The second hinge portion 121 includes two opposing ear plates with circular through holes. The distance between the two ear plates matches the thickness of the first hinge portion 420 on the operating plate 400, thus facilitating hinged connection. The operating plate 400 is a rectangular plate structure. Along the width direction of the operating plate 400... One end is provided with a first hinge part 420, wherein the first hinge part 420 includes a block structure with a circular through hole, the thickness of which is adapted to the distance between the two ear plates of the second hinge part 121 on the fixed rod body 120. Then, a pin passes through the circular through hole of the first hinge part 420 and the circular through holes of the two ear plates of the second hinge part 121 to realize the hinge connection between the operating plate body 400 and the fixed rod body 120. Nuts or other locking devices are provided at both ends of the pin to prevent the pin from falling off during use.

[0031] In the above structure, the water outlet pipe 110 is placed inside the fixed rod 120, which reduces the likelihood of the water outlet pipe 110 being damaged by collisions or scratches from mechanical equipment and debris in the construction environment. This effectively protects the water outlet pipe 110, extends its service life, and reduces equipment maintenance and replacement costs. The operating plate 400 is hinged to the second hinge 121 of the fixed rod 120 through the first hinge part 420. During the filling operation, the worker can easily rotate the operating plate 400 to the working position. The rotation operation of the operating plate 400 is simple and convenient, reducing the difficulty of operation for workers and improving work efficiency.

[0032] In addition, the device includes a support rod 430, one end of which has a third hinge portion 431 and the other end has a support portion 432. A fourth hinge portion 122 is located below the second hinge portion 121 on the side end of the fixed rod 120. The third hinge portion 431 and the fourth hinge portion 122 are hinged together. The support rod 430 can rotate around the hinge axis, allowing the support portion 432 to abut against and support the end of the operating plate 400 opposite the water needle 111. A slot 440 is provided on the end face of the operating plate 400 opposite the water needle 111, and the support portion 432 can rotatably engage with the slot 440.

[0033] In this embodiment, as Figure 1 As shown, a fourth hinge portion 122 is provided on the side of the fixed rod 120 below the second hinge portion 121. The fourth hinge portion 122 includes two opposing lugs with circular through holes. The distance between the two lugs is adapted to the thickness of the third hinge portion 431 to facilitate installation and hinge. The support rod 430 is a rod-shaped structure, and a third hinge portion 431 is provided at one end along its length. The third hinge portion 431 includes a block-shaped structure with a circular through hole. The diameter of the through hole is adapted to the pin used for hinge. To achieve flexible rotation, the third hinge part 431 and the fourth hinge part 122 are hinged together, allowing the support rod 430 to rotate vertically relative to the fixed rod 120. The other end of the support rod 430 is a support part 432. When the operating plate 400 rotates to the working position (horizontal state), the support rod 430 is rotated, causing the support part 432 of the support rod 430 to rotate and abut against the lower end face of the operating plate 400, thus supporting the operating plate 400 and providing support force. In addition, a slot 440 is provided on the lower end face of the operating plate 400 to engage with the support part 432. When the support rod 430 supports the operating plate 400, the support part 432 of the support rod 430 engages in the slot 440, serving as a limiting function.

[0034] In the above structure, the support rod 430 provides support for the operating plate 400, effectively preventing the operating plate 400 from shaking or shifting during the filling process. This allows the water needle 111 to accurately aim at the blister mud for water injection, improving the accuracy and consistency of filling and ensuring the filling quality of each blister mud. In addition, the locking mechanism between the support rod 430 and the operating plate 400 is simple and convenient, allowing workers to quickly complete the support and disassembly operations. When it is necessary to replace the blister mud or perform equipment maintenance, the position of the operating plate 400 can be quickly adjusted, improving the flexibility and operability of the equipment.

[0035] Specifically, such as Figure 2 As shown, the fixed rod 120 has a receiving groove 123 on its side end, and the support rod 430 can be rotatably accommodated in the receiving groove 123. The receiving groove 123 is located on the side end of the fixed rod 120, and its opening position corresponds to the fourth hinge part 122 to ensure that the support rod 430 can be smoothly rotated and stored in it. The length of the receiving groove 123 is slightly larger than the length of the support rod 430, and its width and depth are adapted to the outer diameter of the support rod 430, ensuring that the support rod 430 can be tightly embedded in the receiving groove 123, while not being difficult to store or remove due to insufficient space. When the support rod 430 is not in use, it can be rotated and stored in the receiving groove 123 of the fixed rod 120, avoiding the support rod 430 occupying additional space. This makes the entire water-filled mud filling device more compact, easier to store and transport. In addition, the receiving groove 123 provides a storage environment for the support rod 430, which can prevent the support rod 430 from being bumped, scratched or damaged by the outside when it is idle.

[0036] In addition, the device also includes a clamping cylinder 450, which has a holding space 451 for containing water-soaked mud. One end of the clamping cylinder 450 has a receiving opening 452 that communicates with the holding space 451, and the other end has a snap-fit ​​block 453. The working end face 410 has a snap-fit ​​groove 411, and the snap-fit ​​block 453 and the snap-fit ​​groove 411 are engaged and snap-fitted together.

[0037] In this embodiment, the clamping cylinder 450 has a cylindrical structure, forming an internal holding space 451 for containing water-soluble mud. The size and shape of this space are determined according to the size and shape of the water-soluble mud to ensure that the water-soluble mud can be placed tightly inside, avoiding shaking or displacement during the filling process. The upper end of the clamping cylinder 450 is provided with a receiving opening 452 that communicates with the holding space 451. The size of the receiving opening 452 is slightly larger than the outer diameter of the water-soluble mud to facilitate the smooth insertion or removal of the water-soluble mud. The bottom end of the clamping cylinder 450 is provided with a snap-fit ​​block 453, and the working end face 410 of the operating plate 400 is provided with a snap-fit ​​groove 411. The shape and size of the snap-fit ​​groove 411 match the snap-fit ​​block 453 to facilitate the insertion and removal of the snap-fit ​​block 453.

[0038] The main function of the clamping cylinder 450 is to fix the sludge. Through the engagement of the snap-fit ​​block 453 and the snap-fit ​​groove 411, the clamping cylinder 450 is firmly fixed to the working end face 410 of the operating plate 400. During the sludge filling process, this ensures the sludge maintains a stable position, preventing shaking or displacement due to water flow impact or other external forces. This ensures that the water needle 111 can accurately inject water into the sludge, improving filling accuracy and consistency. The installation of the sludge is completed by snapping the snap-fit ​​block 453 of the clamping cylinder 450 into the snap-fit ​​groove 411 on the operating plate 400. After filling, simply pull the snap-fit ​​block 453 out of the snap-fit ​​groove 411 to easily remove the filled sludge. This operation method is simple and quick, improving work efficiency.

[0039] The working end face 410 is provided with an overflow groove 412, the clamping cylinder 450 is snapped into the overflow groove 412, the bottom of the overflow groove 412 is provided with an overflow port 413, and the overflow port 413 is detachably connected to an overflow pipe 414.

[0040] In this embodiment, the overflow trough 412 is provided on the working end face 410 of the operating plate 400. It is an annular or rectangular groove to ensure that it can accommodate a certain amount of overflow liquid. The bottom of the overflow trough 412 is inclined towards the overflow port 413 at a certain angle. The clamping cylinder 450 is snapped into the overflow trough 412. The overflow port 413 is located at the lowest position of the bottom of the overflow trough 412. It is usually a circular or square opening for detachable connection with the overflow pipe 414. The overflow pipe 414 can be a rubber tube or a plastic hose. One end of the overflow pipe 414 is detachably connected to the overflow port 413. The connection method can be a threaded connection, a snap-fit ​​connection, or a rubber sealing sleeve connection, etc. The other end can be connected to a collection container or drainage system to collect and treat the overflow water.

[0041] The above structure can effectively prevent liquid spillage and contamination. The overflow tank 412 can collect the spilled water in a timely manner, preventing water from flowing directly onto the workbench or the ground, thereby preventing the working environment from being contaminated and maintaining the cleanliness and hygiene of the workplace.

[0042] In the installation structure of the foot-operated water valve mechanism 300, the filling body 100 includes a mounting base 130, and one end of the fixed rod 120 relative to the water needle 111 is connected to the mounting base 130. The mounting base 130 is provided with an installation space 131, and the installation space 131 is provided with an opening for the water injection pipe 200 to pass through. The foot-operated water valve mechanism 300 is connected to the installation space 131. The foot-operated water valve mechanism 300 includes a first opening 310, a second opening 320 and a foot-operated valve assembly 330. The first opening 310 is connected to the water injection pipe 200, and the second opening 320 is connected to the water outlet pipe 110. The foot-operated valve assembly 330 controls the connection or blockage of the first opening 310 and the second opening 320 by foot pedal action.

[0043] In this embodiment, as Figure 1 , Figure 2 As shown, a mounting base 130 is fixedly connected to the bottom end of the fixed rod 120. The mounting base 130 has an internal mounting space 131, the size and shape of which are determined according to the dimensions and structure of the foot-operated water valve mechanism 300. The side end of the mounting base 130 has an opening for the water injection pipe 200 to pass through. The diameter of the opening is slightly larger than the outer diameter of the water injection pipe 200 to ensure that the water injection pipe 200 can pass through smoothly. The foot-operated water valve mechanism 300 has a first opening 310 and a second opening 320. The first opening 310 communicates with the water injection pipe 200, and the second opening 320 communicates with the water outlet pipe. The foot pedal valve assembly 330 controls the connection or blockage of the first opening 310 and the second opening 320 by foot pedal action. The foot pedal valve assembly 330 generally includes a valve body 331, a valve core, a spring, and a foot pedal 332. The valve body 331 is the outer shell of the foot pedal valve assembly 330, and has an internal channel for connecting the first opening 310 and the second opening 320. The valve core is located inside the valve body 331 and can move up and down within the valve body 331 to control the flow of water. The spring is installed between the valve core and the valve body 331 to provide the force for the valve core to return to its original position. When the foot pedal 332 is not pressed, the spring pushes the valve core to the closed position, blocking the connection between the first opening 310 and the second opening 320. When the foot pedal 332 is pressed, the spring is compressed, the valve core moves downward, and the connection channel between the first opening 310 and the second opening 320 is opened. The structure is more compact, reducing the floor space required and making it easy to use in different workplaces. The secure connection between the fixed rod 120 and the mounting base 130, as well as the foot-operated water valve mechanism 300 installed in the installation space 131, ensure that the entire filling body 100 remains stable during operation, reducing the impact of shaking or vibration on the filling effect.

[0044] More specifically, the foot valve assembly 330 includes a valve body 331 and a foot pedal 332, the foot pedal 332 being hinged to the valve body 331, and an elastic support 340 being provided between the foot pedal 332 and the bottom wall of the mounting space 131. An anti-slip pad 333 is provided on the foot pedal 332.

[0045] In this embodiment, the foot pedal 332 is a rectangular plate structure for easy operation. The elastic support 340 is a spring structure, with one end of the spring tightly connected to the bottom surface of the foot pedal 332 and the other end fixedly connected to the bottom wall of the mounting space 131. In its natural state, the spring provides upward support to the foot pedal 332, keeping it in its initial position. At this time, the foot valve assembly 330 is closed, blocking the passage between the first opening 310 and the second opening 320. When the operator steps on the foot pedal 332, the spring is compressed, and the foot pedal 332 rotates around the pin, opening the passage and allowing water flow. An anti-slip pad 333 is provided on the upper surface of the foot pedal 332. The anti-slip pad 333 is made of rubber or other high-friction materials, and its shape is perfectly fitted to the foot surface of the foot pedal 332. The surface of the anti-slip pad 333 has various textures, such as uneven stripes or grid patterns, to further increase the friction between the sole of the foot and the foot pedal 332.

[0046] The foot pedal 332, in conjunction with the elastic support 340, allows the operator to easily control the water flow by simply stepping on the foot pedal 332 to overcome the spring force. After the operator releases the foot pedal 332, the elastic support 340 quickly returns the foot pedal 332 to its initial position, automatically resetting the foot valve assembly 330. This effectively prevents continuous water flow due to incomplete valve closure, avoiding water waste and potential adverse effects on the working environment. The anti-slip pad 333 on the foot pedal 332 increases the friction between the foot and the pedal, effectively preventing accidental operation due to slipping.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
