Description

Technical Field

[0001] This utility model belongs to the technical field of material transport vehicles, and in particular relates to a low-density powder and granular material transport vehicle. Background Technology

[0002] Low-density powder material transport vehicles are a type of transport vehicle specifically designed for transporting powder materials with a bulk density of ≤700kg / m³. This type of transport vehicle typically consists of a special-purpose vehicle chassis, a bulk cement tank, an air pipeline system, and an automatic unloading device. They are suitable for transporting dry powder materials with a particle diameter of no more than 0.1mm, such as fly ash, cement, lime powder, ore powder, and granular alkali.

[0003] When loading existing powder and granular material transport vehicles, the loading pipe is aligned with the inlet of the tank, and then the loading pipe is opened to allow the powder and granular material to enter the tank. Because the material of powder and granular material is very light, it is easy for material dust to overflow from the inlet during loading. For some special materials of powder and granular material, the escaped dust can easily cause environmental pollution and harm the health of workers. Utility Model Content

[0004] This utility model addresses the problem in the prior art that the lightweight nature of powdery materials makes it easy for dust to overflow from the feed inlet during loading. Furthermore, for certain special powdery materials, the escaped dust can easily cause environmental pollution and harm workers' health. The following technical solution is proposed:

[0005] A low-density powder material transport vehicle includes: a vehicle body and a tank. The top of the tank is provided with a feed inlet, the top of the feed inlet is fitted with a cover, a baffle is installed inside the feed inlet, the bottom end of the baffle is fixedly connected to the inner wall of the tank, a cylinder is fixedly installed on the outside of the feed inlet, one end of the cylinder is fixedly connected to an air inlet pipe, an airbag is movably installed inside the feed inlet, and the other end of the air inlet pipe is connected to the inside of the airbag.

[0006] As a preferred embodiment of the above technical solution, a return spring is symmetrically fixedly connected inside the feed inlet, and the other end of the return spring is fixedly connected to the outside of the baffle cloth.

[0007] As a preferred embodiment of the above technical solution, a discharge pipe is fixedly connected to the outer surface of the tank, an auxiliary sleeve is fixedly sleeved on the outer side of one end of the discharge pipe, and a flexible tube is fixedly sleeved inside the auxiliary sleeve.

[0008] As a preferred embodiment of the above technical solution, an inner tube is rotatably installed inside the discharge pipe, and the other end of the inner tube is rotatably installed inside the flexible hose.

[0009] As a preferred embodiment of the above technical solution, a motor is fixedly installed at the top of the discharge pipe inside the auxiliary sleeve, and the output shaft of the motor and the outer side of the inner tube are movably connected by the same belt.

[0010] As a preferred embodiment of the above technical solution, a connecting rod is fixedly connected to the inner wall of the inner tube, and a stirring blade is fixedly sleeved on the outer side of the connecting rod.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) This utility model inflates the airbag inside the feed inlet, causing it to expand and gradually reduce the inner diameter of the airbag. During the expansion of the airbag, the outer baffle moves synchronously towards the center point of the feed inlet, so that the top part of the baffle fits against the outside of the filling pipe and the bottom end of the baffle is connected to the inner wall of the tank. This effectively reduces the amount of material dust overflowing from the feed inlet during the filling process, thereby reducing the pollution of the environment caused by dust.

[0013] (2) By installing the stirring blade, this utility model avoids the operator opening the valve too violently in the early stage of discharge, which would cause a large amount of material to rush into the discharge pipe and cause the discharge pipe to be blocked. The rotating stirring blade can break up the blocked material at the discharge pipe position, thereby improving the discharge efficiency and ensuring that the material can be discharged stably from the discharge pipe.

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] Example 1

[0025] This utility model provides a low-density powder and granular material transport vehicle, such as Figures 1 to 8 As shown, the system includes a vehicle body 1 and a tank body 2. A feed inlet 3 is located at the top of the tank body 2, and a cap 4 is installed at the top of the feed inlet 3. A baffle 5 is installed inside the feed inlet 3, and the bottom end of the baffle 5 is fixedly connected to the inner wall of the tank body 2. A cylinder 6 is fixedly installed on the outside of the feed inlet 3, and an air inlet pipe 7 is fixedly connected to one end of the cylinder 6. An airbag 8 is movably installed inside the feed inlet 3, and the other end of the air inlet pipe 7 is connected to the airbag 8. The outer ring of the airbag 8 is fixedly connected to the inner wall of the feed inlet 3. When the cylinder 6 inflates the airbag 8, the airbag 8 expands and its inner diameter gradually decreases. During the expansion of the airbag 8, the baffle 5 on its inner ring moves synchronously. The bottom end of the baffle 5 is fixedly connected to the inner wall of the tank body 2, thus changing the baffle 5 from a vertical state to a state where the top end contracts inward. This allows the moving part of the baffle 5 to contact the outside of the loading pipe, thereby preventing material dust from overflowing from the feed inlet 3 during loading and reducing environmental pollution.

[0026] like Figure 4 and Figure 5 As shown, a return spring 9 is symmetrically fixedly connected inside the feed inlet 3. The other end of the return spring 9 is fixedly connected to the outside of the baffle 5. During the process of the airbag 8 expanding and driving the top of the baffle 5 to move, the return spring 9 is stretched and deformed. When the tank 2 is filled and the airbag 8 returns to its original state, the tension of the return spring 9 drives the top of the baffle 5 to move in the opposite direction, so that the baffle 5 returns to the vertical state.

[0027] like Figures 1 to 8As shown, a discharge pipe 10 is fixedly connected to the outer surface of the tank body 2. An auxiliary sleeve 11 is fixedly sleeved on the outer side of one end of the discharge pipe 10. A hose 12 is fixedly sleeved inside the auxiliary sleeve 11. Existing powder and granular material transport vehicles also include an air inlet valve installed on the tank body 2. In actual discharge, the air inlet valve on the tank body 2 needs to be opened to inject air into the tank body 2. When the pressure inside the tank body 2 reaches the discharge value, the valve on the discharge pipe 10 is opened to allow the material in the tank body 2 to be discharged along the discharge pipe 10 and from the hose 12, thus completing the discharge of powder and granular materials. The above are all existing technologies and will not be described in detail here.

[0028] like Figures 6 to 8 As shown, an inner tube 14 is rotatably installed inside the discharge pipe 10, and the other end of the inner tube 14 is rotatably installed inside the hose 12. The top of the discharge pipe 10 is fixedly installed inside the auxiliary sleeve 11. The output shaft of the motor 13 and the outer side of the inner tube 14 are movably connected to the same belt 15, and the outer side of the inner tube 14 is in close contact with the inner wall of the belt 15. When the motor 13 works, it drives the inner tube 14 to rotate through the action of the belt 15. A connecting rod 16 is fixedly connected to the inner wall of the inner tube 14, and an agitator 17 is fixedly sleeved on the outer side of the connecting rod 16. When the inner tube 14 rotates, it drives the connecting rod 16 to rotate synchronously, thereby causing the agitator 17 to start rotating and breaking up the material stuck at the position of the discharge pipe 10. This prevents the discharge pipe 10 from becoming blocked when the tank 2 is discharging material, ensuring stable discharge operation.

[0029] Working principle: When it is necessary to load material into tank 2, the operator aligns the loading inlet pipe with the inlet 3 on tank 2, and then starts cylinder 6. Gas enters into airbag 8 through air inlet pipe 7 to inflate it, thereby causing airbag 8 to expand. During the inflation process, the inner radius of airbag 8 gradually decreases, which drives the baffle 5 in the inner ring to move and make the baffle 5 adhere to the outside of the loading pipe. The bottom end of the baffle 5 is connected to the inner wall of tank 2, so that the baffle 5 changes from the original vertical state to the state in which the top part contracts inward. This can block the gap between the loading inlet pipe and the inlet 3, thereby reducing the overflow of low-density powder material from the inlet 3 when tank 2 is being loaded, and reducing the pollution caused by dust emission to the environment.

[0030] When discharging material from tank 2, some accumulated material will gather at the discharge pipe 10 and cause blockage. Then, motor 13 starts working and drives inner pipe 14 to rotate through belt 15. When inner pipe 14 rotates, it drives connecting rod 16 inside to rotate synchronously, so that stirring blade 17 can break up the material blocked at the discharge pipe 10, thereby avoiding material blockage during discharge and affecting the discharge rate.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
