DETAILED DESCRIPTION

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0027] like Figures 1-3 As shown, this embodiment provides a sand-spreading device for anti-skid purposes on a track-mounted sightseeing vehicle, fixed to the vehicle frame, including a sand storage box 100, a spray pipe 300, and a power component. The sand storage box 100 is generally rectangular in shape and is used to store quartz sand. A sand leakage hole 101 is provided at the bottom of the sand storage box 100, through which the quartz sand flows out under the influence of gravity. The first end of the spray pipe 300 communicates with the sand leakage hole 101 to allow sand to enter, and the second end is close to the wheel and faces the top surface of the track to discharge sand. The spray pipe 300 is always positioned in front of the wheel in the direction of travel and is relatively close to the wheel, which allows the quartz sand sprayed from the spray pipe 300 to promptly enter the rolling range of the wheel. The power unit includes a central section 200 with a channel, which is located at the bottom of and connected to the sand storage tank 100. An auger 220 is arranged within the channel of the central section 200. A motor 210 driving the auger 220 is located at the first end of the central section 200, and the second end is connected to the spray pipe 300. Quartz sand flowing from the sand leakage hole 101 first enters the channel of the central section 200, where the auger 220 drives the quartz sand into the spray pipe 300. The installation height of the sand storage tank 100 is higher than the bottom of the wheel, causing the spray pipe 300 to be arranged at an angle, allowing the quartz sand entering the spray pipe 300 to slide directly out. The overall structure is compact and simple, occupies little space, and can be integrated and mounted on the vehicle frame.

[0028] Furthermore, the intermediate section 200 is elongated, with a rectangular or circular cross-section and a circular cross-section for its internal channels, resulting in an overall cylindrical or cuboid shape. When designed as a cuboid, it provides a larger contact area with the sand storage box 100. When cylindrical, connecting components are needed on both sides of the intermediate section 200 and between it and the sand storage box 100 to ensure a more stable connection. A feed inlet is provided at a position corresponding to the sand leakage hole 101 in the intermediate section 200, allowing the quartz sand flowing from the sand leakage hole 101 to smoothly enter the intermediate section 200. The intermediate section 200 can be fixed to the sand storage box 100 by welding, riveting, or bolting.

[0029] In use: the set sand storage box 100 is used to provide quartz sand, and the auger 220 in the power member can continuously push the quartz sand in the sand storage box 100 to the spray pipe 300, and the quartz sand is released onto the track through the spray pipe 300 to achieve the purpose of preventing slipping. The auger 220 not only can push the quartz sand, but also can stir the quartz sand, avoiding the blockage caused by the caking of the quartz sand.

[0030] Referring to Figure 4 In some embodiments, the bottom of the sand storage box 100 is configured with an inclined surface 130 with the left high and the right low, and the normal direction of the inclined surface 130 extends to the left and downward. The sand leakage hole 101 is located on the inclined surface 130, and the middle part 200 is attached to the inclined surface 130. The inclined surface 130 is provided so that the sand leakage hole 101 has a larger outlet area, and the working area of the auger 220 is larger.

[0031] Further, the central axis of the spray pipe 300 coincides with the central axis of the middle part 200. Since the middle part 200 is attached to the inclined surface 130, the long strip-shaped middle part 200 is also arranged obliquely, and the spray pipe 300 can be directly extended downward by the middle part 200, that is, it can be extended to the position close to the wheel.

[0032] Referring to Figures 1-2 In some embodiments, the bottom of the sand storage box 100 is configured as a horizontal surface 120, the sand leakage hole 101 is located on the horizontal surface 120, and the middle part 200 is attached to the horizontal surface 120.

[0033] Further, since the middle part 200 is in a horizontal state, the spray pipe 300 needs to be kept in an inclined state extending toward the wheel after being connected with the middle part 200, so the spray pipe 300 is set to be inclined downward by the middle part 200.

[0034] In some embodiments, the sand storage box 100 is also provided with a mounting bracket 110, and the mounting bracket 110 is provided with a through hole through which the bolt 111 passes. The mounting bracket 110 is used to fix the sand scattering device on the vehicle frame, and since the overall structure is simple, the mounting bracket 110 on the sand storage box 100 can be used for fixing. The mounting bracket 110 can be a plate-shaped member fixedly connected with the sand storage box 100, and a corresponding threaded hole or through hole is constructed on the vehicle frame, so that the mounting bracket 110 can be fixed on the vehicle frame by the bolt 111. The fixing of the overall sand scattering device is realized.

[0035] In some embodiments, the second end of the spray pipe 300 is further provided with a sealing plug 310, which is rotationally connected to the side of the spray pipe 300, and an elastic member is further arranged between the sealing plug 310 and the spray pipe 300 to abut the sealing plug 310 against the pipe opening. The sealing plug 310 is opened by an opening assembly during sanding. When the quartz sand is not needed to be sprayed, the pipe opening of the spray pipe 300 is blocked by the sealing plug 310, so as to avoid foreign matters from blocking the spray holes, and water vapor from entering the spray pipe 300 and the intermediate part 200 to cause the quartz sand to be hardened. The elastic member can be a torsion spring, and the sealing plug 310 is kept in a closed state under the pushing of the torsion spring. When the opening assembly opens the sealing plug 310, the torsion spring is compressed to store energy, and the sealing plug 310 is released when it is needed to be closed.

[0036] In some embodiments, the opening assembly includes a pull wire 400 and a telescopic rod 410. One end of the pull wire 400 is connected to the outside of the sealing plug 310, and the other end is connected to the action part of the telescopic rod 410. The pull wire 400 is in a slightly taut state, and the pull wire 400 can timely transmit the pulling force to the sealing plug 310 when the telescopic rod 410 acts. The connection part of the sealing plug 310 and the spray pipe 300 is preferably the upper part of the pipe opening of the spray pipe 300, and the pull wire 400 is preferably arranged above the spray pipe 300, and a roller 320 is further arranged on the spray pipe 300 to support the pull wire 400.

[0037] In some embodiments, the telescopic rod 410 is an electric telescopic rod 410 or a pneumatic telescopic rod 410, and the telescopic rod 410 is fixed on the intermediate part 200.

[0038] In some embodiments, the sealing plug 310 is provided with an extension part 311 extending outwardly corresponding to the connection part of the sealing plug 310 and the spray pipe 300, and the pull wire 400 is connected to the extension part 311. The upper part of the pipe opening of the spray pipe 300 is fixed with a mounting seat 330, which axially extends forward, and a gap is formed in the mounting seat 330. The extension part 311 is arranged in the gap, and a pin shaft 331 is further arranged on the mounting seat 330, which penetrates the extension part 311, so that the extension part 311 rotationally moves relative to the mounting seat 330 through the pin shaft 331.
