Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust suppression spray technology, specifically a dust suppression spray device for mining operations. Background Technology
[0002] Dust suppression spray devices for mining operations are used to reduce dust pollution during mining processes. They primarily utilize a high-pressure pump to pressurize water to a certain pressure, which is then delivered through high-pressure pipelines to specially designed nozzles. The nozzles atomize the water into fine water mist particles. These water mist particles collide and combine with dust particles in the air, causing the dust particles to settle due to gravity, thus achieving the purpose of dust suppression.
[0003] In existing technology, workers start the water pump by pressing the start button or operating the corresponding control switch. The water pump then draws water from the tank and delivers it through the water pipe to the spray nozzle, where it is atomized into fine water mist particles and sprayed into the air. This causes the dust particles to absorb moisture, increasing their weight and thus accelerating their settling under gravity, thereby reducing the concentration of dust in the air. However, after the spraying operation is completed, the water in the tank needs to be manually drained to prevent the equipment and pipes from freezing and cracking at low temperatures. This manual operation is cumbersome and results in low work efficiency.
[0004] Therefore, we propose a dust suppression spray device for mining operations. Utility Model Content
[0005] The purpose of this utility model is to provide a dust suppression spray device for mining operations to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression spray device for mining operations, comprising a support frame, a rotating frame rotatably connected to the top of the support frame, a mist cannon pipe rotatably connected inside the rotating frame, a fan fixedly connected inside the mist cannon pipe, a hydraulic rod rotatably connected inside the rotating frame, multiple casters fixedly connected to the bottom of the support frame, a water tank fixedly connected inside the support frame, and a drainage mechanism for portable drainage provided inside the water tank.
[0007] The drainage mechanism includes a limiting frame and a fixing frame. One end of the limiting frame is fixedly connected to the inside of the water tank. A sliding rod is slidably connected inside the limiting frame. A conical plug is fixedly connected to the bottom of the sliding rod. The top of the fixing frame is fixedly connected to the top of the inside of the water tank. A lever is rotatably connected inside the fixing frame. A pressing rod is rotatably connected inside the lever. A washer is fixedly connected to the outside of the pressing rod. A spring is sleeved on the outside of the pressing rod.
[0008] The drive end of the hydraulic rod is rotatably connected to the bottom of the fog cannon pipe.
[0009] The pressing rod is externally slidably connected to the inside of the support frame.
[0010] One end of the spring is fixedly connected to the top of the inside of the water tank, and the other end of the spring is fixedly connected to the top of the gasket.
[0011] The sliding rod is externally rotatably connected to the inside of the lever.
[0012] The outside of the conical plug is in contact with the inside of the water tank.

[0014] The annular tube is fixedly connected to the outside of the fog cannon tube, and multiple nozzles are installed on the outside of the annular tube.
[0015] This utility model has at least the following beneficial effects: by pressing the pressing rod downwards and simultaneously stretching the spring, the lever is rotated, which in turn pulls the sliding rod upwards inside the limiting frame, thereby causing the conical plug to contact and separate from the water tank outlet, conveniently draining the remaining water inside the water tank. Finally, the spring generates a reaction force to reset the conical plug for easy next use. Workers only need to press the pressing rod to drain the water, without the need for complicated tools or cumbersome procedures. Even in harsh environments such as mines, workers can easily complete the drainage of remaining water, improving work efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Example 1
[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a dust suppression spray device for mining operations, including a support frame 1, which serves as the basic support structure for the entire spray device. It is made of high-strength steel and has an overall frame shape, possessing a robust and stable structure capable of withstanding the weight of other components of the spray device as well as vibrations and impacts that may occur during operation. A rotating frame 2 is rotatably connected to the top of the support frame 1. The internal bearings of the rotating frame 2 ensure that the rotating frame 2 can rotate flexibly and smoothly, thereby enabling a wider spray coverage area and adapting to the dust suppression needs of different locations in the mine. A fog cannon pipe 3 is rotatably connected inside the rotating frame 2. The fog cannon pipe 3 is an overall slender cylindrical shape and is made of corrosion-resistant, high-strength stainless steel alloy material to adapt to the harsh working environment of the mine. A fan 11 is fixedly connected inside the mist cannon pipe 3. The fan 11 generates strong wind, atomizing the water from the water tank 9 into fine water mist particles, which are then sprayed out at high speed to form a large-area mist curtain, effectively adsorbing and settling dust particles in the air. A hydraulic rod 8 is rotatably connected inside the rotating frame 2. When the hydraulic system is working, the hydraulic rod 8 can precisely adjust the elevation and depression angles of the mist cannon pipe 3 through its extension and retraction, allowing the mist cannon pipe 3 to be flexibly adjusted in the vertical direction, further improving the flexibility and accuracy of the spray coverage. Multiple casters 4 are fixedly connected to the bottom of the support frame 1. The casters 4 facilitate the movement of the entire spraying device to a designated location for precise spraying operations. A water tank 9 is fixedly connected inside the support frame 1. The water tank 9 is used to store the water required for spraying operations and is made of high-strength stainless steel, which has good corrosion resistance and sealing performance. The water tank 9 is equipped with a drainage mechanism for portable drainage.
[0024] The drainage mechanism includes a limiting frame 13 and a fixing frame 16. One end of the limiting frame 13 is fixedly connected to the inside of the water tank 9. The limiting frame 13 has a smooth guide groove inside, which provides guidance for the sliding of the subsequent structure. A sliding rod 14 is slidably connected inside the limiting frame 13. The sliding rod 14 is a stainless steel metal rod with a precision-machined surface, which has good straightness and smoothness to ensure smooth sliding within the limiting frame 13. A conical plug 15 is fixedly connected to the bottom of the sliding rod 14. The conical plug 15 is made of rubber material and can fit tightly with the outlet of the water tank 9 to achieve a good sealing effect and prevent water leakage in the water tank 9. The top of the fixing frame 16 is fixedly connected to the top of the inside of the water tank 9. The fixing frame 16 is U-shaped and is used to provide a fulcrum for the rotation of the subsequent structure. A lever 17 is rotatably connected inside the fixing frame 16. The lever 17 amplifies the force of the operation and changes the direction of the force, thereby driving the sliding rod 14 to move upward. A pressing rod 18 is rotatably connected inside the lever 17. The pressing rod 18 is used by the operator to press and control the rotation of the lever 17. A gasket 19 is fixedly connected to the outside of the pressing rod 18. The gasket 19 is used to provide a foundation for the installation of the subsequent reset structure. A spring 20 is sleeved on the outside of the pressing rod 18. The spring 20 is used to provide elastic force for the sliding reset of the pressing rod 18.
[0025] The drive end of the hydraulic rod 8 is rotatably connected to the bottom of the fog cannon pipe 3. The extension of the drive end of the hydraulic rod 8 drives the fog cannon pipe 3 to rotate, thereby adjusting the spray angle of the fog cannon pipe 3 and achieving precise dust suppression.
[0026] The external sliding connection of the pressing rod 18 is to the inside of the support frame 1. When the operator presses the pressing rod 18, it slides inside the support frame 1, causing the lever 17 to rotate, thereby realizing the sliding of the conical plug 15.
[0027] One end of the spring 20 is fixedly connected to the top of the inside of the water tank 9, and the other end of the spring 20 is fixedly connected to the top of the gasket 19. The fixing of both ends of the spring 20 ensures that it will not fall off during the extension and retraction of the spring 20, thereby providing a restoring force so that the drainage mechanism can automatically return to the initial state to seal and store water after the drainage operation is completed, making it convenient for the next use.
[0028] The external rotatable connection of the sliding rod 14 is to the inside of the lever 17. The rotation of the lever 17 drives the sliding rod 14 to slide upward, changing the direction of the force and improving the ease of operation.
[0029] The outer side of the conical plug 15 contacts the inside of the water tank 9. In its natural state, the conical plug 15, relying on its own weight and the elastic force of the spring 20, tightly fits against the outlet, achieving a good sealing effect and preventing water leakage from the water tank 9. When drainage is required, pressing the pressing rod 18 rotates the lever 17, which in turn pulls the sliding rod 14 upward, causing the conical plug 15 to separate from the outlet, allowing the water in the water tank 9 to drain out through the outlet.
[0030] Example 2
[0031] The water tank 9 is externally fixedly connected to a water inlet pipe 10, which is made of sturdy steel pipe with threads on the outside for threaded connection with the water source pipe. The water tank 9 is internally fixedly connected to a water pump 12, which is a centrifugal pump specially designed for industrial spraying. It can generate strong suction when rotating at high speed to quickly extract water from the water tank 9. The output end of the water pump 12 is fixedly connected to a connecting water pipe 7, which is made of flexible rubber hose with good extensibility to facilitate angle adjustment of the fog cannon. The other end of the connecting water pipe 7 is fixedly connected to a ring pipe 5.
[0032] The annular pipe 5 is fixedly connected to the outside of the fog cannon pipe 3. The annular pipe 5 is arranged in a ring around the outside of the fog cannon pipe 3. Multiple nozzles 6 are installed on the outside of the annular pipe 5. The nozzles 6 are evenly distributed on the outer surface of the annular pipe 5, which enables the water flowing in from the annular pipe 5 to be sprayed out at a specific angle and shape under pressure, forming a fine water mist that combines with dust particles, thereby effectively suppressing the dust generated during mining.
