Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, and in particular to a waterproof, dustproof, and heat-insulating device for transport vehicles. Background Technology

[0002] Waterproof, dustproof, and heat-insulating devices for transport vehicles are mainly used to create a stable, clean, and temperature-appropriate environment during cargo transportation, protecting the quality and integrity of the goods and ensuring that they are not affected by moisture, dust contamination, or temperature changes during transit. In practical applications, waterproof, dustproof, and heat-insulating devices for transport vehicles typically require the following technologies:

[0003] 1. High-quality sealing materials ensure the airtightness of the joints between the carriages and the edges of doors and windows, effectively preventing the intrusion of moisture and dust;

[0004] 2. High-efficiency thermal insulation materials, such as polyurethane foam and aerogel, reduce the impact of external temperature on the interior of the carriage.

[0005] 3. An advanced air filtration system filters the air entering the cabin, preventing dust from entering;

[0006] 4. The intelligent temperature control system can accurately regulate and maintain a stable temperature inside the carriage;

[0007] 5. A robust and durable protective coating enhances the waterproof, dustproof, and wear-resistant properties of the vehicle's surface.

[0008] Currently, various equipment and methods are used to achieve waterproofing, dustproofing, and heat insulation for transport vehicles. Some manufacturers enhance waterproofing and dustproofing by adding rubber sealing strips at the joints of the cargo compartment, but this method is prone to aging and damage, requiring frequent replacement. Other manufacturers use integrated insulated cargo compartments, but these are more expensive and heavier, increasing the vehicle's energy consumption. Some manufacturers install air conditioning and heating equipment inside the cargo compartment to control the temperature, but their effectiveness is limited in extreme environments.

[0009] For example, a Chinese patent discloses a waste heat insulation device for an asphalt concrete transport vehicle (patent number: CN216861296U). High-temperature fumes generated during vehicle operation are discharged through an exhaust pipe. A heat-conducting rod absorbs and transfers the high temperature from the exhaust pipe to the inside of the water tank. A ceramic heating element inside the water tank, along with the heat transferred by the heat-conducting rod, heats the water inside the tank. Once a certain temperature is reached, the ceramic heating element stops working. The heat transferred by the heat-conducting rod further helps to keep the water warm. A water pump transfers the water from the tank to a second heat-conducting pipe via a first connecting pipe, then back to the first heat-conducting pipe via a delivery pipe, and finally back to the tank via the second connecting pipe for further heating and insulation. The first and second heat-conducting pipes effectively heat and insulate the interior of the cargo compartment, efficiently utilizing the waste heat generated by the transport vehicle to insulate the cargo compartment, preventing the asphalt concrete from solidifying upon cooling, saving energy, and reducing the transportation cost of asphalt concrete.

[0010] However, the above method has a prominent problem: the device only uses one compartment for storage and loading / unloading. During the unloading process, the material is discharged directly through the discharge pipe, which makes it difficult to control the unloading speed. It may be too fast or too slow. The lack of a buffer channel causes uneven unloading. Unstable unloading can lead to material accumulation or splashing, affecting the unloading process. Utility Model Content

[0011] To address the shortcomings of existing technologies, this utility model provides a waterproof, dustproof, and heat-insulating device for transport vehicles. It solves the technical problem that the device only uses one compartment for storage and loading / unloading. During the unloading process, the material is directly discharged through the discharge pipe, which easily leads to difficulty in controlling the unloading speed. The material may be too fast or too slow, and the lack of a buffer channel causes uneven and unstable unloading, which can lead to material accumulation or splashing, thus affecting the unloading operation.

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] A waterproof, dustproof, and heat-insulating device for a transport vehicle includes a transport vehicle body. The transport vehicle body has an internal discharge mechanism for discharging materials. The discharge mechanism includes a discharge bin and a discharge control valve pipe. The discharge bin is located inside the transport vehicle body, and the discharge control valve pipe is sleeved inside the transport vehicle body. The inner surface of the discharge bin is provided with a sealing sliding mechanism. The sliding mechanism includes a mounting base, a first connecting rod, a second connecting rod, a sealing baffle, and a stepper motor. The mounting base is fixedly connected inside the discharge bin. The first connecting rod is rotatably connected inside the mounting base. The second connecting rod is rotatably connected to the outer surface of the first connecting rod. The sealing baffle is rotatably connected to the outer surface of the second connecting rod. The stepper motor is fixedly connected to the outer surface of the mounting base, and the first connecting rod is sleeved on the outer surface of the stepper motor.

[0014] Preferably, a sealing gasket is fixedly connected to the end of the sealing baffle away from the second connecting rod, and T-shaped sliders are fixedly connected to both sides of the sealing baffle.

[0015] Preferably, the transport vehicle body has a storage compartment inside, and a heater / insulator is fixedly connected inside the transport vehicle body.

[0016] Preferably, a heat-conducting pipe is fitted onto the outer surface of the heating and heat preservation device.

[0017] Preferably, the storage bin contains two rotatable spiral stirring rods, and each of the two spiral stirring rods has a synchronous wheel sleeved on its outer surface.

[0018] Preferably, a timing belt is fitted onto the outer surfaces of the two timing pulleys, and a drive motor is fixedly connected inside the transport vehicle body.

[0019] Preferably, both of the spiral stirring rods have sleeves fitted onto their outer surfaces.

[0020] Preferably, each of the two sleeves has two rotatably connected stirring blades inside, and the outer surfaces of the two spiral stirring rods and the four stirring blades are all fitted with bevel gears.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. When material feeding is required, the stepper motor is started. The output shaft of the stepper motor drives the first connecting rod to rotate within the mounting base. The rotation of the first connecting rod pulls the second connecting rod to move. The deformation generated by the rotation between the first and second connecting rods pulls the sealing baffle upward, opening the connection channel between the storage bin and the discharge bin. During the conveying process, the sealing baffle blocks and seals the material, ensuring the airtightness and purity of the material during transportation. The sealing process also enhances the insulation effect and effectively prevents external impurities from entering, ensuring the purity of the material during transportation. During the feeding process, the material is first discharged from the storage bin into the discharge bin before being fed out, increasing the buffer time and space and ensuring the uniformity of feeding.

[0023] 2. The output shaft of the drive motor drives one spiral stirring rod to rotate. The spiral stirring rod drives two spiral stirring rods to rotate synchronously through a synchronous pulley and synchronous belt. The rotation of the two spiral stirring rods stirs and mixes the material. Through the spiral surfaces of the two spiral stirring rods, the material can be driven to generate stirring vortices along the spiral guide during rotation, promoting the overall circulation of the material. During the rotation of the spiral stirring rods, the sleeve rotates. The bevel gears that mesh with the surfaces of the two stirring blades drive the stirring blades to rotate. Through the meshing of the two bevel gears, the stirring blades rotate on their own axis while being driven by the sleeve to revolve around the central axis, increasing the diversity of stirring and mixing, increasing the flow speed of the material away from the heating and insulation unit, and increasing the uniformity of heating.

[0030] This application provides a waterproof, dustproof, and heat-insulating device for a transport vehicle. It effectively solves the problem of devices using only one compartment for storage and loading / unloading. During loading, materials are directly discharged through the discharge pipe, leading to uncontrollable loading speeds that can fluctuate too quickly or too slowly. The lack of a buffer channel causes uneven and unstable loading, resulting in material accumulation or splashing, affecting the loading process. When loading is required, a stepper motor is activated. The stepper motor output shaft drives the first connecting rod to rotate within the mounting base. The rotation of the first connecting rod pulls the second connecting rod, and the deformation generated by the rotation between the first and second connecting rods pulls the sealing baffle upwards, opening the connection channel between the storage compartment and the discharge compartment. During transport, the sealing baffle blocks and seals the material, ensuring airtightness and material purity. The sealing also enhances the heat insulation effect, effectively preventing external impurities from entering and ensuring material purity during transport. During loading, the material first flows from the storage compartment into the discharge compartment before being unloaded, increasing buffer time and space, and ensuring uniform loading.

[0031] Example

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that the device only uses one compartment for storage and loading / unloading. During the unloading process, the material is directly discharged through the discharge pipe, which easily leads to difficulty in controlling the unloading speed, sometimes too fast or too slow. The lack of a buffer channel causes uneven unloading, and unstable unloading can lead to material accumulation or splashing, affecting the unloading operation. The overall idea is as follows: A waterproof, dustproof, and heat-insulating device for a transport vehicle, including a transport vehicle body 11, with a discharge pipe inside the transport vehicle body 11 for... The material discharge mechanism includes a discharge bin 12 and a discharge control valve pipe 13. The discharge bin 12 is located inside the transport vehicle body 11, and the discharge control valve pipe 13 is sleeved inside the transport vehicle body 11. A sliding mechanism for sealing is provided on the inner surface of the discharge bin 12. The sliding mechanism includes a mounting base 14, a first connecting rod 15, a second connecting rod 16, a sealing baffle 17, and a stepper motor 18. The mounting base 14 is fixedly connected inside the discharge bin 12, the first connecting rod 15 is rotatably connected inside the mounting base 14, and the second connecting rod 16 is rotatably connected to the first connecting rod 17. The outer surface of the first connecting rod 15 is rotatably connected to the outer surface of the second connecting rod 16. The stepper motor 18 is fixedly connected to the outer surface of the mounting base 14. The first connecting rod 15 is sleeved on the outer surface of the stepper motor 18. A sealing gasket 19 is fixedly connected to the end of the sealing baffle 17 away from the second connecting rod 16. T-shaped sliders 21 are fixedly connected to both sides of the sealing baffle 17. Both T-shaped sliders 21 are slidably connected inside the discharge bin 12. A storage bin 22 is opened inside the transport vehicle body 11. The storage bin 22 and the discharge bin 12 are connected. When it is necessary to perform... During the unloading operation, the stepper motor 18 is started. The output shaft of the stepper motor 18 drives the first connecting rod 15 to rotate within the mounting base 14. The rotation of the first connecting rod 15 pulls the second connecting rod 16 to move. The deformation generated by the rotation between the first connecting rod 15 and the second connecting rod 16 pulls the sealing baffle 17 to slide upward, opening the connection channel between the storage bin 22 and the discharge bin 12. During the conveying process, the sealing baffle 17 blocks and seals the material to ensure the airtightness and purity of the material during transportation, and enhances the heat preservation effect through the sealing process.

[0033] A heating and insulation unit 23 is fixedly connected inside the transport vehicle body 11. A heat-conducting pipe 24 is sleeved on the outer surface of the heating and insulation unit 23, and the heat-conducting pipe 24 is sleeved inside the storage bin 22. Two spiral stirring rods 25 are rotatably connected inside the storage bin 22. Synchronous pulleys 26 are sleeved on the outer surface of each of the two spiral stirring rods 25, and synchronous belts 27 are sleeved on the outer surface of the two synchronous pulleys 26. A drive motor 28 is fixedly connected inside the transport vehicle body 11, and the two spiral stirring rods 25 are sleeved on the outer surface of the drive motor 28. Materials to be transported are fed into the storage bin 22 opened in the transport vehicle body 11 through a discharge control valve pipe 13. The materials are stored in the storage bin 22. Workers transport the materials by driving the transport vehicle body 11. During driving, the heating and insulation unit 23 connected inside the transport vehicle body 11 is activated, and the heating and insulation unit 23 conducts heat to the storage bin 22 through the heat-conducting pipe 24. The materials stored in the storage bin 22 are insulated. The transport vehicle body 11 is equipped with a battery power source for the drive heater and heat preservation device 23, drive motor 28, and stepper motor 18. When the materials need to be discharged for use upon arrival at the destination, the sealing baffle 17 is pulled and slid. When the sealing baffle 17 is in place, it seals the gap between the discharge bin 12 and the storage bin 22 through the sealing gasket 19 connected to its surface to prevent the materials from spilling out during transportation. The sliding of the sealing baffle 17 connects the transport vehicle body 11 and the discharge bin 12. The materials stored in the storage bin 22 are discharged along the discharge control valve pipe 13 connected to the discharge bin 12 for use. The device is fully shielded and sealed during the transportation process to prevent dust accumulation. The surface of the transport vehicle body 11 is inclined to prevent rainwater from contacting the materials during transportation. The materials are heated through the heat conduction pipe 24 to ensure that they are kept at a constant temperature during transportation.

[0034] Both spiral stirring rods 25 have sleeves 29 fitted onto their outer surfaces. Two stirring blades 31 are rotatably connected inside each sleeve 29. Bevel gears 32 are fitted onto the outer surfaces of both spiral stirring rods 25 and the four stirring blades 31. During the conveying and heating process, the drive motor 28 is started. The output shaft of the drive motor 28 drives one spiral stirring rod 25 to rotate. The spiral stirring rod 25 drives both spiral stirring rods 25 to rotate synchronously via a synchronous pulley 26 and a synchronous belt 27. The rotation of the two spiral stirring rods 25 mixes the material. The spiral surfaces of the two spiral stirring rods 25, during rotation, drive the material to generate a stirring vortex along the spiral guide, promoting overall material circulation. During the rotation of the spiral stirring rods 25, the sleeves 29 rotate. The bevel gears 32 meshing with the surfaces of the two stirring blades 31 drive them to rotate. The meshing of the two bevel gears 32 causes the stirring blades 31 to rotate while being driven by the sleeves 29 to revolve, increasing the diversity of mixing, increasing the flow rate of the material away from the heating and insulation unit 23, and increasing the uniformity of heating.

[0035] To address the problems existing in the prior art, this utility model provides a waterproof, dustproof, and heat-insulating device for a transport vehicle. When material unloading is required, the stepper motor 18 is started. The output shaft of the stepper motor 18 drives the first connecting rod 15 to rotate within the mounting base 14. The rotation of the first connecting rod 15 pulls the second connecting rod 16 to move. The deformation generated by the rotation between the first connecting rod 15 and the second connecting rod 16 pulls the sealing baffle 17 upward to slide, opening the connection channel between the storage bin 22 and the discharge bin 12. During the conveying process, the sealing baffle 17 blocks and seals the material, ensuring the airtightness and purity of the material during transportation. The sealing process also enhances the heat insulation effect, effectively preventing external impurities from entering and ensuring the purity of the material during transportation. During the unloading process, the material is first discharged from the storage bin 22 into the discharge bin 12 before being unloaded, increasing the buffer time and space and ensuring the uniformity of unloading.

[0036] Working principle:

[0037] The first step involves feeding the material to be transported into the storage bin 22 within the transport vehicle body 11 via a discharge control valve 13. The material is then stored in the storage bin 22. Workers drive the transport vehicle body 11 to move the material. During driving, the heating and insulation unit 23 connected within the transport vehicle body 11 is activated. The heating and insulation unit 23 transfers heat to the stored material in the storage bin 22 via heat pipes 24, providing insulation. The transport vehicle body 11 is equipped with a battery power source that drives the heating and insulation unit 23, a drive motor 28, and a stepper motor 18. When the material needs to be discharged for use upon reaching its destination, the vehicle body 11 is pulled... The dynamic sealing baffle 17 slides. When the sealing baffle 17 is placed, it seals the gap between the discharge bin 12 and the storage bin 22 by the sealing gasket 19 connected to the surface to prevent the material from spilling out during transportation. The sliding of the sealing baffle 17 connects the transport vehicle body 11 and the discharge bin 12. The material stored in the storage bin 22 is discharged along the discharge control valve pipe 13 connected in the discharge bin 12 for use. The device is fully shielded and sealed during the transportation process to prevent dust accumulation. The surface of the transport vehicle body 11 is inclined to prevent rainwater and other substances from contacting the material during transportation. The material is heated by the heat conduction pipe 24 to ensure that it is kept at a constant temperature during transportation.

[0038] The second step involves starting the stepper motor 18 when material feeding is required. The output shaft of the stepper motor 18 drives the first connecting rod 15 to rotate within the mounting base 14. The rotation of the first connecting rod 15 pulls the second connecting rod 16 to move. The deformation generated by the rotation between the first connecting rod 15 and the second connecting rod 16 pulls the sealing baffle 17 upward, opening the connection channel between the storage bin 22 and the discharge bin 12. During the conveying process, the sealing baffle 17 blocks and seals the material, ensuring the airtightness and purity of the material during transportation. The sealing also enhances the heat preservation effect. During the conveying and heating process, the drive motor 28 is started. The output shaft of the drive motor 28 drives a spiral stirring rod 25 to rotate. 5. The two spiral stirring rods 25 are driven to rotate synchronously by the synchronous pulley 26 and the synchronous belt 27. The rotation of the two spiral stirring rods 25 stirs and mixes the material. Through the spiral surface of the two spiral stirring rods 25, the material can be driven to generate a stirring vortex along the spiral guide during rotation, which promotes the overall circulation of the material. During the rotation of the spiral stirring rods 25, the sleeve 29 rotates. During the rotation of the spiral stirring rods 25, the bevel gears 32 on the surface of the two stirring blades 31 are driven to rotate. Through the meshing of the two bevel gears 32, the stirring blades 31 are driven to rotate on their own axis during the revolution driven by the sleeve 29, which increases the diversity of stirring and mixing, increases the flow speed of the material away from the heating and heat preservation unit 23, and increases the uniformity of heating.
