Description

Technical Field

[0001] This utility model relates to the technical field of mining processing equipment, specifically to a tracked coal and water pump truck for mining. Background Technology

[0002] Currently, the crushing systems of existing tracked coal and water pump trucks used in mining typically consist of only a single crusher main structure. Material is directly fed into the crusher's feed inlet by a conveying device, and after crushing, it enters the subsequent processing flow. However, in actual industrial applications, this traditional feeding and crushing mode has gradually revealed many technical defects that urgently need to be addressed, seriously affecting the stability of equipment operation and operational efficiency. First, fluctuations in material feed flow rate can easily lead to frequent overflows in the crusher. During coal mining and transportation, the amount of raw coal or coal slime is affected by various factors such as the output of the mining equipment and the speed of the conveyor belt, often resulting in significant flow fluctuations. When the material flow rate increases instantaneously, a large amount of material entering the crusher directly cannot be accommodated and processed by the crushing chamber in time, easily accumulating at the crusher's feed inlet and inside the crushing chamber, leading to material overflow. Overflowing material not only scatters onto the equipment body and work site, increasing the workload of on-site cleanup, but may also mix into critical components such as the equipment's tracked walking mechanism and power transmission system, causing component jamming, accelerated wear, and other malfunctions. In severe cases, it may even lead to equipment shutdown for maintenance, significantly reducing operational continuity. Secondly, the material enters the crusher at a non-uniform speed, causing the crushing load to fluctuate periodically. When the material supply increases suddenly, the core working components of the crusher, such as the moving and stationary jaw plates and the rotor, must withstand a sudden increase in impact load, which not only generates severe vibration and noise but also leads to a decrease in the overall operational stability of the equipment. Conversely, when the material supply decreases suddenly, the crusher operates under light or no load. This drastic fluctuation in load causes frequent impact damage to the equipment's power system and transmission system, shortening the equipment's service life. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a tracked coal and water pump truck for mining. By adding a blowout preventer above the crusher, a buffer is provided before the material enters the crusher to prevent excessive flow of excess material that could cause overflow at the crusher. At the same time, the blowout preventer also ensures stable feeding to the crusher, improving the stability of equipment operation and reducing wear on the equipment.

[0004] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a mine tracked coal and water pump truck, including a base, a traveling track is provided below the base, and a coal preparation module is provided above the base. The coal preparation module includes an execution unit and a drive unit. The drive unit includes a control box and a hydraulic station. The execution unit includes a crusher and a transfer water tank. A material receiving port is provided above the crusher. A blowout preventer is provided above the material receiving port. A conveying pump is provided inside the transfer water tank.

[0005] As a further improvement to the above technical solution: The blowout preventer has a feed inlet on its side wall and a discharge port at the bottom for use with the receiving port. The blowout preventer also has a pressure relief port at the top.

[0006] The blowout preventer has a relief groove in the middle that corresponds to the position of the crusher, and an observation port is provided on at least one side wall of the blowout preventer.

[0007] The blowout preventer is equipped with a baffle located between the inlet and outlet, and a flow gap is reserved between the baffle and the bottom of the blowout preventer.

[0008] The feed inlet is equipped with inclined guide plates on both sides.

[0009] The lower end of the crusher is provided with a discharge pipe, and an intercepting water tank is provided between the discharge pipe and the transfer water tank. A conveying pipeline is provided between the intercepting water tank and the transfer water tank.

[0010] The base is provided with a positioning leg at its lower part, and the positioning leg is provided with a leveling push rod that is connected to the hydraulic station at its upper part.

[0011] The number of positioning outriggers is multiple, and they are divided into two groups symmetrically distributed on both sides of the traveling track.

[0012] The beneficial effects of this utility model embodiment are as follows: The mine tracked coal and water pump truck includes a base, a traveling track is provided below the base, and a coal preparation module is provided above the base. The coal preparation module includes an execution unit and a drive unit. The drive unit includes a control box and a hydraulic station. The execution unit includes a crusher and a transfer water tank. A material receiving port is provided above the crusher, and a blowout preventer is provided above the material receiving port. By adding a blowout preventer above the crusher, buffering is achieved before the material enters the crusher to avoid excessive flow of excess material, which could cause overflow at the crusher. At the same time, the blowout preventer can also ensure the stability of the material supply to the crusher, thereby improving the stability of equipment operation and reducing wear on the equipment. The crushed coal-water mixture is discharged through the discharge pipe at the bottom of the crusher and first enters the interception water tank for preliminary solid-liquid separation and impurity interception treatment to remove large impurities or foreign objects in the mixture that may affect the operation of the conveying pump. The qualified coal-water mixture after interception treatment flows into the transfer water tank through the conveying pipeline between the interception water tank and the transfer water tank to avoid damage to the conveying pump caused by large solid particles.

[0015] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] like Figure 1-4 As shown, the tracked coal and water pump truck of this embodiment includes a base 1, with a traveling track 2 for moving the equipment and providing the vehicle with the power to move, and positioning outriggers 23 for fixing the position during operation. There are multiple positioning outriggers 23, which are symmetrically distributed in two groups on both sides of the traveling track 2 to achieve stable support. A leveling push rod 24 is provided on its upper part. The leveling push rod 24 is connected to the hydraulic station 11 mentioned later. The hydraulic drive completes the raising and lowering and leveling operation of the outriggers to ensure the stability of the equipment during operation.

[0017] A coal preparation module is installed above the base 1, mainly consisting of an execution unit 3 and a drive unit 4. The drive unit 4 provides power and control support for the execution unit 3, including a control box 10 and a hydraulic station 11. The execution unit 3 is responsible for the specific coal-water crushing and conveying operations, including a crusher 5 and a transfer water tank 6. The transfer water tank 6 is also equipped with a conveying pump 9 for material conveying.

[0018] The upper part of the crusher 5 is provided with a receiving port 7. To prevent material from splashing during operation, a blowout shield 8 is provided above the receiving port 7. The blowout shield 8 is adapted to the position of the crusher 5. The side wall of the blowout shield 8 is provided with a feed inlet 12, the bottom is provided with a discharge port 13 that is precisely matched with the receiving port 7, and the upper part is provided with a pressure relief port 14 for balancing the pressure inside the box, so as to ensure that the material passes through smoothly while avoiding pressure accumulation.

[0019] The blowout preventer 8 has a relief groove 15 in the middle that corresponds to the position of the crusher 5 to avoid installation interference; at least one side wall is also provided with an observation port 16 to facilitate the operator to check the internal operation in real time.

[0020] Inside the blowout preventer 8, a baffle 17 is provided between the feed inlet 12 and the discharge outlet 13. A flow gap 18 is reserved between the baffle 17 and the bottom of the blowout preventer 8, which can buffer and guide the incoming material. Inclined guide plates 19 are also provided on both sides of the discharge outlet 13 to further guide the material to fall accurately into the receiving outlet 7.

[0021] The lower end of the crusher 5 is equipped with a discharge pipe 20 for discharging the crushed material. An interception water tank 21 is installed between the discharge pipe 20 and the transfer water tank 6. The material and water after interception are transported into the transfer water tank 6 through the conveying pipe 22 between the interception water tank 21 and the transfer water tank 6, and finally transported by the conveying pump 9 in the transfer water tank 6.

[0022] The working principle / assembly process of this solution: The equipment obtains mobility through the traveling tracks under the base and can flexibly travel to the designated area of ​​coal mine operation; after reaching the target position, multiple positioning outriggers symmetrically distributed on both sides of the traveling tracks are activated, and the leveling push rod connected to the hydraulic station provides hydraulic driving force to complete the synchronous lifting and leveling operation of the outriggers, so that the equipment is detached from the track support and is in a stable state. The coal-water mixture enters the equipment through the feed inlet on the side wall of the blowout preventer. The blowout preventer precisely connects to the receiving port at the top of the crusher through the bottom discharge port. Its closed structure effectively prevents material splashing during operation. At the same time, the baffle between the feed inlet and discharge port inside the blowout preventer buffers the material through the reserved flow gap, preventing the material from directly impacting the crusher. The inclined guide plates on both sides guide the material to fall precisely into the receiving port. The pressure relief port at the top balances the air pressure inside the box, ensuring smooth material passage. The observation port allows operators to monitor the feeding and buffering status in real time. The control box and hydraulic station in the drive unit provide power support and operation control for the crusher. After the crusher receives the coal-water mixture falling into the receiving port, it starts the crushing mechanism to crush the coal material in it to meet the particle size requirements of subsequent conveying. The crushed coal-water mixture is discharged through the discharge pipe at the bottom of the crusher and first enters the interception water tank for preliminary solid-liquid separation and impurity interception, removing large impurities or foreign objects in the mixture that may affect the operation of the conveying pump. The qualified coal-water mixture after interception flows into the transfer water tank through the conveying pipeline between the interception water tank and the transfer water tank, realizing the centralized collection of materials.
