It includes a tank body, a first motor, a second push rod, a first auger, a second auger, a filter, and a hollow interlayer. A discharge port is located on the lower right side of the tank body, and a truck bed is located below the tank body. The first motor is mounted on the left side of a support plate, and a lead screw with a threaded sleeve is mounted on the left side of the first motor. A first push rod is mounted above a second rotating seat, and a second push rod is mounted on the side of the first push rod closest to the tank body. The second motor is mounted in the middle of the left side of the tank body, and a first rotating shaft is mounted on the right side of the second motor. A first auger is mounted on the first rotating shaft, and a second auger is mounted on the second rotating shaft. This utility model, through the coordinated use of the third motor, the second rotating shaft, and the second auger, can convey material in the discharge port from top to bottom, preventing material blockage of the discharge port.

[0003] The above-mentioned documents and existing technologies have the following technical problems: The volume of the existing tank-type ash trucks is fixed. During transportation, when the vehicle brakes, starts, or travels on bumpy roads, the dust inside the tank is easily shaken due to inertia. The large amount of dust shaking inside the tank will affect the vehicle's center of gravity distribution and increase the safety risks such as rollover. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a variable-volume tank unloading vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a variable volume tank ash unloading vehicle, comprising a vehicle body, a frame provided on the surface of the vehicle body, a tank provided on the surface of the frame, a hydraulic cylinder provided inside the tank, a protective cover provided on the surface of the hydraulic cylinder, a mesh plate provided at the end of the hydraulic cylinder, a pressure sensor provided at the bottom of the mesh plate, a guide rod provided inside the tank, and a feed pipe provided on the top surface of the tank.

[0006] Preferably, an air compressor is provided on the side of the vehicle frame, and an air intake pipe is provided on the surface of the air compressor.

[0007] Preferably, the end of the air inlet pipe is connected to the side of the tank, and the surface of the air inlet pipe is provided with an electrically controlled valve.

[0008] Preferably, the side of the tank is provided with a discharge pipe, and the surface of the discharge pipe is provided with a discharge valve.

[0009] Preferably, the shape of the mesh plate is adapted to the tank body, and guide grooves are provided on both sides of the mesh plate.

[0010] Preferably, the shape and position of the guide groove correspond to the guide rod, and the mesh plate is slidably connected to the guide rod through the guide groove.

[0011] Preferably, one end of the protective cover is connected to the surface of the hydraulic cylinder, and the other end of the protective cover is connected to the surface of the mesh plate.

[0012] Beneficial effects

[0013] In this invention, a hydraulic cylinder, a mesh plate, and a protective cover are used. When a small amount of dust is transported in the tank, the hydraulic cylinder, under the action of the hydraulic system, pushes the mesh plate connected to it downwards. This causes the mesh plate to press the dust in the tank, making the volume of the tank match the dust content, effectively limiting the space for dust movement, lowering the center of gravity of the dust inside, reducing the instability caused by dust shaking, and reducing the probability of accidents such as rollovers during vehicle operation, especially during braking and turning. This ensures the safety of the driver and other personnel and vehicles on the road. At the same time, the specially designed bellows-style protective cover can extend and retract with the piston rod as the hydraulic cylinder moves the mesh plate up and down, preventing dust from entering the hydraulic cylinder and avoiding wear on the seals between the piston and cylinder.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4 A variable-volume tank unloading vehicle includes a vehicle body 1, which serves as the basic carrier of the entire unloading vehicle, providing a supporting structure for vehicle movement and enabling the various components to work together. A frame 2 is mounted on the surface of the vehicle body 1, which is a key structure connecting the vehicle body 1 to components such as the tank 3, ensuring the relative stability of the components during vehicle movement. An air compressor 4 is mounted on the side of the frame 2. The air compressor 4 mainly consists of a motor, a compressor body, and an air storage tank. The motor provides power to drive the compressor body to compress air and store it in the air storage tank. The air compressor 4 generates compressed air, providing a power source for pneumatic unloading. After the compressed air enters the tank 3, it fluidizes the dust, reducing the friction between dust particles and the friction with the tank 3 wall, thus allowing the dust to be discharged from the tank 3 more smoothly through the discharge pipe 8, improving unloading efficiency. An air inlet pipe 5 is mounted on the surface of the air compressor 4, with its end connected to the side of the tank 3. An electrically controlled valve 6 is mounted on the surface of the air inlet pipe 5. The function is to deliver the compressed air generated by the air compressor 4 to the inside of the tank 3, ensuring that the compressed air can accurately reach the designated location to participate in the dust fluidization process. The electric control valve 6 on the pipeline can control the on / off state and flow rate of the compressed air. The tank 3 is located on the surface of the frame 2. The tank 3 is the core component for storing and transporting dust. It has the characteristic of variable volume and can adjust the internal space according to the actual amount of dust transported to meet different loading requirements. The top surface of the tank 3 is equipped with a feed pipe 7, which is the channel for dust to enter the tank 3. When loading dust, the dust is transported to the inside of the tank 3 through the feed pipe 7 by special loading equipment (such as conveyor belt, loader, etc.) to realize the loading operation of the ash truck. The side of the tank 3 is equipped with a discharge pipe 8, and the surface of the discharge pipe 8 is equipped with a discharge valve 9. The discharge pipe 8 is the channel for dust to be discharged from the tank 3 during unloading. When the discharge valve 9 is opened, the dust in the tank is discharged from the tank 3 through the discharge pipe 8 under the combined action of gravity and compressed air, and transported to the designated unloading location.

[0024] A hydraulic cylinder 10 is installed inside the tank body 3. The hydraulic cylinder 10 consists of main components such as a cylinder barrel, piston, and piston rod. The cylinder barrel is fixed inside the tank body 3, and the piston can move up and down inside the cylinder barrel. One end of the piston rod is connected to the piston, and the other end is connected to the bottom mesh plate 11. The piston is driven to move up and down inside the cylinder barrel by high-pressure oil provided by the hydraulic system, which in turn drives the bottom mesh plate 11 to move up and down. During transportation, the mesh plate 11 is pushed down to press down the dust, reducing dust shaking and thus reducing the internal volume of the tank body 3. A protective cover 13 is provided on the surface of the hydraulic cylinder 10. One end of the protective cover 13 is connected to the surface of the hydraulic cylinder 10, and the other end of the protective cover 13... One end is connected to the surface of the mesh plate 11. The protective cover 13 is accordion-shaped and can be extended and folded. The protective cover 13 is fitted over the piston rod of the hydraulic cylinder 10. During the up-and-down movement of the mesh plate 11 driven by the hydraulic cylinder 10, it extends or folds with the extension and retraction of the piston rod. Its main function is to prevent dust from entering the hydraulic cylinder 10 and avoid dust from causing wear on the seals between the piston and the cylinder, thereby extending the service life of the hydraulic cylinder 10 and ensuring its stable operation. The end of the hydraulic cylinder 10 is provided with a mesh plate 11. The shape of the mesh plate 11 is adapted to the tank body 3. The mesh plate 11 has a certain strength and air permeability. The size of the mesh can ensure that... The dust can pass through during unloading, and its movement is effectively limited during pressing. During transportation, it moves downwards under the push of hydraulic cylinder 10, pressing the dust inside the tank 3, limiting its movement space, and reducing the risk of vehicle instability caused by dust movement. A pressure sensor 15 is installed at the bottom of the mesh plate 11. When the mesh plate 11 presses down on the dust, the pressure on the pressure sensor 15 increases as the dust is gradually compacted. A suitable pressure threshold is pre-set based on the characteristics of different types of dust and transportation safety requirements. When the pressure sensor 15 detects that the pressure has reached this threshold, it means that the dust has been pressed down. The pressure sensor 15 transmits a signal to the vehicle control system, which then issues a command to stop the hydraulic cylinder 10, thereby stopping the downward pressure of the mesh plate 11. Guide grooves 14 are provided on both sides of the mesh plate 11, and the shape and position of the guide grooves 14 correspond to the guide rods 12. The mesh plate 11 is slidably connected to the guide rods 12 through the guide grooves 14. The tank body 3 is equipped with guide rods 12, which cooperate with the guide grooves 14 on both sides of the mesh plate 11 to provide guidance for the up and down movement of the mesh plate 11, ensuring that the mesh plate 11 moves smoothly and accurately under the drive of the hydraulic cylinder 10, and preventing problems such as deviation or jamming of the mesh plate 11 during the movement.

[0025] During loading, park the vehicle in the appropriate position, open the top feed pipe 7 of the tank 3, and use a conveyor belt or other equipment to load the dust into the tank 3. Then, under the action of the hydraulic system, the hydraulic cylinder 10 pushes the connected mesh plate 11 downward, thereby causing the mesh plate 11 to press the dust inside the tank 3. When the pressure sensor 15 detects that the pressure has reached the threshold, it means that the dust has been pressed. At this time, the pressure sensor 15 transmits a signal to the vehicle control system, and the system issues a command to stop the hydraulic cylinder 10, thereby realizing the pressing of the mesh plate 11. The downward pressure stops, making the volume inside the tank 3 match the dust content, effectively limiting the dust movement space, lowering the center of gravity of the dust inside, and reducing the instability caused by dust shaking. When unloading, first drive the vehicle to the unloading point and stop it, pull up the handbrake, start the hydraulic system, operate the control valve to make the hydraulic cylinder 10 drive the screen plate 11 to rise, release the downward pressure on the dust, then open the discharge valve 9 and start the air compressor 4, allowing the dust to be discharged through the discharge pipe 8 under the action of gravity and compressed air. After unloading is completed, close the discharge valve 9 and the air compressor 4. Specific Implementation Example 2:

[0027] A variable-volume tank ash unloading vehicle, based on the basic structure in Specific Embodiment 1, further discloses the following: Rotary nozzles and a high-pressure air pump are installed inside the tank 3. The rotary nozzles are distributed at the top of the tank 3 and connected to the high-pressure air pump via pipes. The high-pressure air pump generates high-pressure gas, which is delivered to the rotary nozzles via pipes. The nozzles can rotate 360 ​​degrees, evenly spraying the high-pressure gas into all corners inside the tank 3. After unloading is completed, a dust self-cleaning device is activated. The high-pressure gas is ejected from the rotary nozzles, impacting the residual dust inside the tank 3, causing it to detach from the tank 3 walls and bottom, and discharged through the discharge pipes 8 with the airflow. This effectively reduces manual cleaning workload, improves vehicle turnover efficiency, and avoids problems such as tank 3 corrosion and contamination of materials transported in subsequent trips due to dust residue.

[0028] In summary:

[0029] 1. The system employs a hydraulic cylinder 10, a mesh plate 11, and a protective cover 13. When a small amount of dust is transported within the tank 3, the hydraulic cylinder 10, under the action of the hydraulic system, pushes the connected mesh plate 11 downwards. This causes the mesh plate 11 to press down on the dust within the tank 3, ensuring that the volume of the tank 3 matches the dust content. This effectively restricts the movement space of the dust, lowers the center of gravity of the dust, and reduces instability caused by dust movement. This lowers the probability of accidents such as rollovers during vehicle operation, especially during braking and turning, thus ensuring the safety of the driver and other personnel and vehicles on the road. Simultaneously, the specially designed bellows-style protective cover 13 extends and retracts with the piston rod as the hydraulic cylinder 10 moves the mesh plate 11 up and down, preventing dust from entering the hydraulic cylinder 10 and avoiding wear on the seals between the piston and cylinder.
