Description

Technical Field

[0001] This invention relates to a tanker truck, specifically to a powder material transport vehicle for transporting powder and capable of rapid discharge. Background Technology

[0002] A powder or granular material transport vehicle is a transport device used to transport powdery or granular materials. It includes a discharge pipe, through which the powdery or granular material is discharged from the vehicle's tank during discharge. Existing powder or granular material transport vehicles typically have a conical bottom plate, gradually decreasing in elevation from the outer perimeter to the center; a section of the discharge pipe is located in the upper middle part of the bottom plate and extends downwards. Existing discharge pipes have a telescopic sleeve at one end inside the tank, which can move up and down. However, the movement of the telescopic sleeve is often achieved through a complex structure, making the movement process difficult to control, and the separated material is prone to clogging at the back or inside of the telescopic sleeve. Summary of the Invention

[0003] The main objective of this invention is to provide a powder material transport vehicle, which aims to solve the problem that existing powder material transport vehicles have a complex and difficult-to-control telescopic sleeve movement mechanism at the end of the discharge pipe.

[0004] This invention provides a powder and granular material transport vehicle, which includes a tank body. An installation hole is provided on the outer side of the tank body near the bottom. A discharge pipe extending towards the middle of the tank body is installed on the installation hole. The section of the discharge pipe extending into the tank body includes a transverse conveying section and a vertical feeding section. One end of the transverse conveying section near the inner wall of the tank body extends out from the installation hole, and the other end of the transverse conveying section away from the inner wall of the tank body is connected to the vertical feeding section. The vertical feeding section extends towards the bottom of the tank body, and a telescopic sleeve is provided at the lower end of the vertical feeding section. A feed inlet is provided at the lower end of the telescopic sleeve. The telescopic sleeve is fitted onto the vertical feeding section and slides and rotates up and down along the vertical feeding section. The telescopic sleeve is also connected to a driving device for driving the telescopic sleeve to slide up and down. The driving device includes a base, on which a telescopic device is hinged. An inclined slide rail is provided on the outside of the telescopic sleeve, and an annular slider is movably connected to the slide rail. The annular slider surrounds the telescopic sleeve, and the upper end of the telescopic device is connected to the annular slider through a hinge.

[0005] Preferably, the telescopic device is a hydraulic cylinder, which includes a mounting base, a cylinder barrel, and a piston rod. The mounting base is provided with a rotating hole, and the base is provided with a pin, which is inserted into the rotating hole.

[0006] Preferably, the base includes a U-shaped plate with a rounded bottom, and the pin is fixed to the two vertical plates of the U-shaped plate.

[0007] Preferably, the expansion joint is connected to a control terminal, which is located outside the tank.

[0008] Preferably, the control terminal is a remote controller.

[0009] Preferably, there are two telescopic joints, which are arranged symmetrically about the telescopic sleeve.

[0010] Preferably, the lower part of the telescopic sleeve is provided with a funnel-shaped suction port.

[0011] Preferably, the lower part of the vertical feeding section is an inner cylinder, and the telescopic sleeve is fitted onto the inner cylinder.

[0012] Preferably, the upper part of the telescopic sleeve is further provided with a flexible connecting strip made of elastic material, and the upper and lower ends of the flexible connecting strip are respectively connected to the sleeve body of the telescopic sleeve and the vertical feeding section.

[0013] The powder and granular material transport vehicle provided by this invention has the following advantages compared with existing powder and granular material transport vehicles:

[0014] The powder and granular material transport vehicle provided by this invention features a telescopic sleeve fitted onto the vertical feeding section, allowing the telescopic section to rotate and move up and down within it, thus improving the flexibility of the telescopic sleeve. Simultaneously, during operation, the telescopic device pushes a ring-shaped slider up and down. Since the ring-shaped slider moves on an inclined track, while the telescopic device can only swing up and down in a single plane, the ring-shaped slider's vertical movement enables the telescopic sleeve to rotate. This rotation of the telescopic sleeve causes the surrounding material and material within the sleeve to rotate, thereby increasing the discharge speed and preventing powder material blockage.

[0030] Example 1

[0031] This embodiment provides a powder material transport vehicle, which includes a tank body 1. An installation hole is provided on the outer side of the tank body 1 near the bottom. A discharge pipe extending towards the middle of the tank body 1 is installed on the installation hole. The section of the discharge pipe extending into the tank body 1 includes a transverse conveying section 7 and a vertical feeding section 6. One end of the transverse conveying section 7 near the inner wall of the tank body 1 extends out from the installation hole, and the other end of the transverse conveying section 7 away from the inner wall of the tank body 1 is connected to the vertical feeding section 6. The vertical feeding section 6 extends towards the bottom of the tank body 1, and a telescopic sleeve 14 is provided at the lower end of the vertical feeding section 6. A feed inlet is provided at the lower end of the telescopic sleeve 14. The telescopic sleeve 14 is fitted onto the vertical feeding section 6 and slides and rotates up and down along the vertical feeding section 6. The telescopic sleeve 14 is also connected to a driving device, which drives the telescopic sleeve 14 to slide up and down. The driving device includes a base 4, on which a telescopic device is hinged. An inclined slide rail is provided on the outside of the telescopic sleeve 14, and an annular slider is movably connected to the slide rail. The annular slider surrounds the telescopic sleeve 14. The upper end of the telescopic device is connected to the annular slider through a hinge.

[0032] The powder and granular material transport vehicle provided by this invention has a telescopic sleeve 14 fitted onto the vertical feeding section 6, allowing the telescopic section to rotate and move up and down on the vertical feeding section 6, thus improving the flexibility of the telescopic sleeve 14. Simultaneously, during the operation of the telescopic device, the telescopic device pushes the annular slider to move up and down. Since the annular slider moves on the track, while the telescopic device can only swing up and down in one plane, the annular slider can only move up and down and cannot rotate. When the resistance to the overall up and down movement of the annular slider and the telescopic sleeve 14 is high, the annular slider will drive the telescopic sleeve 14 to rotate. During the rotation of the telescopic sleeve 14, the annular slider moves up and down, thereby simultaneously driving the telescopic sleeve 14 to rotate. The rotation of the telescopic sleeve 14 causes the material nearby and inside the telescopic sleeve 14 to rotate, thereby increasing the discharge speed and preventing powder material blockage.

[0033] Of course, it should be noted that the telescopic distance of the above-mentioned telescopic device should be such that when the annular slider moves to the highest point of the track, while the telescopic sleeve 14 is still at the lowest point of its stroke, it can continue to retract, allowing the telescopic sleeve 14 to rotate and move downwards; simultaneously, when the annular slider moves to the lowest point of the track, while the telescopic sleeve 14 is at the highest point of its stroke, it can still retract, allowing the telescopic sleeve 14 to move downwards. The telescopic sleeve 14 should be on the vertical feed section 6 at both the maximum and minimum arm lengths of the telescopic device. In actual use, since both rotation and vertical movement have certain resistance, rotation and vertical movement are performed synchronously. Of course, when the rotational resistance or the vertical movement resistance is relatively too large, rotation and vertical movement may occur separately. Furthermore, the connection between the annular slider and the telescopic sleeve 14 can be a threaded connection. The inclined track is an externally threaded track, while the annular slider has a corresponding internally threaded groove. The thread should be set to have a large perpendicularity to reduce rotational resistance. Of course, the aforementioned slide rail can also be at least a slanted slide rail, in which the annular slider moves along the slanted slide rail while driving the telescopic sleeve 14 to rotate. The aforementioned slanted slide rail should also be one of the aforementioned tracks.

[0034] Specifically, in this embodiment, the telescopic device is a hydraulic cylinder, which includes a mounting base 5, a cylinder barrel 11, and a piston rod 12. The mounting base 5 has a rotating hole 10, and the base 4 has a pin 18 inserted into the rotating hole 10. The hydraulic cylinder is connected to the base 4 via the rotating hole 10 and the pin 18, ensuring that the hydraulic cylinder can only rotate in a plane perpendicular to the pin 18, thus limiting the rotation of the hydraulic cylinder and preventing it from moving to either side.

[0035] More specifically, in this embodiment, the base 4 is configured as follows: the base 4 includes a U-shaped plate. In order to avoid the base 4 interfering with the rotation of the hydraulic cylinder, the bottom of the U-shaped plate is an arc surface, and the pin 18 is fixed on the two vertical plates of the U-shaped plate.

[0036] Specifically, in this embodiment, since components such as hydraulic cylinders are located inside the tank 1, the telescopic device is connected to a control end for easy control, and the control end is located outside the tank 1.

[0037] More specifically, for further convenient control of the hydraulic cylinder, the control terminal is a remote controller.

[0038] Specifically, in order to improve the uniformity of force distribution on the telescopic sleeve 14 and prevent the telescopic sleeve 14 from deviating to the side, there are two telescopic devices, which are arranged symmetrically about the telescopic sleeve 14.

[0039] Specifically, in this embodiment, in order to improve the material suction effect of the telescopic sleeve 14, a horn-shaped suction port 13 is provided at the lower part of the telescopic sleeve 14.

[0040] Specifically, in this embodiment, the lower part of the vertical feeding section 6 is an inner cylinder 15, and the telescopic sleeve 14 is fitted onto the inner cylinder 15. At this time, the telescopic sleeve 14 and the vertical feeding section 6 can move up and down and rotate. It should be noted that the telescopic length of the hydraulic cylinder should be set so that the telescopic sleeve 14 is always fitted onto the vertical feeding section 6 in any state of the hydraulic cylinder.

[0041] More specifically, in this embodiment, to prevent powdered material from entering between the telescopic sleeve 14 and the vertical feeding section 6, and to prevent air leakage from the gap between the telescopic sleeve 14 and the vertical feeding section 6, a flexible connecting strip made of elastic material is provided on the upper part of the telescopic sleeve 14. The upper and lower ends of the flexible connecting strip are respectively connected to the sleeve body of the telescopic sleeve 14 and the vertical feeding section 6. The aforementioned flexible connecting strip can be an elastic cloth. In actual use, the flexible connecting strip will rotate, wrap around, and overlap, while the elastic flexible connecting strip can maintain a certain amount of deformation.

[0042] Of course, the above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention and should be protected by the present invention.
