Embodiment
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] A traditional trolley sand spreading device generally includes a sandbox 12, a funnel 13 and a sand spill 2. The sand spreading device includes two sandboxes 12, and the two sandboxes 12 are connected together by a connecting plate 17.
[0017] The present invention welds together the sandbox 12 that two specifications are long 15cm * wide 15cm * high 15cm by two crossbars namely connecting plate 17, and sandbox 12 can make and not only be limited to cuboid. In order to overcome the problem of fine sand clogging in wet and other environments, a stirring mechanism is provided in the sandbox 12. There is a pedal 1 under the sandbox 12. The pedal 1 rotates on the bearing through the stirring shaft 16 to drive the stirring mechanism to reciprocate. sports.
[0018] The following is a brief introduction to the mixing mechanism.
[0019] The stirring mechanism mainl...

A novel tram car sand scattering device is disclosed to achieve normal fine sand scattering by tram cars even under wet conditions and other adverse conditions. The sand scattering device is also provided with a stirring mechanism. A pedestal and a stirring shaft are integrated. The stirring shaft is installed on a connecting plate installed in the middle through a bearing, and is fixedly connected to a stirring shaft rotary rod. The stirring shaft rotary rod is connected to a driving rod through a casing pipe sleeving the stirring shaft rotary rod. The driving rod is installed on a connecting rod. The two ends of the connecting rod are hinged through pin rolls to rotating rods at two sides. One of the rotating rods is connected to a tension spring support at a side surface of a sand box through a tension spring. The rotating rods are connected to stirring fan-shaped plates through mobile shafts. The stirring fan-shaped plates are connected to sand stirring rods. The bottom of the sand box is provided with sand leaking holes. Hoppers are disposed right below the sand leaking holes. The sand scattering device effectively avoids a situation that sand is scattered outside tracks. When the sand is wet, the sand scattering device can be normally used, thus avoiding the situations of tram car slipping and increasing the transportation efficiency.
Description
technical field [0001] The invention relates to a rail sand spreading device, in particular to a sand spreading device matched with a tram. Background technique [0002] In order to increase the friction between the rails and the mine wheels, it is usually necessary to sand the surface of the track in order to increase the friction of the track. [0003] Since the original trolley sand spreading device is a pedal swing type, the sand cannot be spread normally when the sand is wet, and the sand is easily scattered to the outside of the track. Now the sand spreading device is transformed into a mixing type, which can also sprinkle sand normally when the sand is wet, and the sand can be aligned and sprinkled on the track without sand leakage. When the pedal is stepped on, the stirring mechanism stirs the sand in the sand box, Make it spread out when needed, release the foot pedal after sand spreading, and the stirring mechanism is reset by spring.
