The invention belongs to the technical field of conveying equipment, and particularly discloses a motor train unit sand adding trolley which comprises a sand storage tank, a high-pressure air pump and a sand conveying channel, an outlet of the high-pressure air pump is connected with the lower end of the sand conveying channel, an outlet of the sand storage tank is connected with the position, close to the lower end, of the sand conveying channel, and the lower wall face in the sand conveying channel is a non-smooth surface. Gravel can be deposited on the lower wall face. The lower wall surface in the sand conveying channel is a non-smooth surface, and gravels can be deposited on the lower wall surface to form a deposition layer. The deposition layer provides a buffer area capable of absorbing and dispersing the impact force of gravels, and the direct contact between the gravels and the channel wall is reduced, so that the friction and abrasion of the lower wall surface in the sand conveying channel are effectively reduced, and the service life of the channel is prolonged. The deposition layer can further reduce stress concentration of the lower wall face in the sand conveying channel, improve the anti-impact capacity and protect the integrity of the channel.

    本发明属于输送设备技术领域,具体公开了一种动车组加砂小车,包括储砂罐、高压气泵和输砂通道,高压气泵的出口与输砂通道的下端连接,储砂罐的出口与输砂通道靠近下端的位置连接,输砂通道内的下壁面为非光滑表面,砂砾能够在下壁面沉积。本发明输砂通道内的下壁面为非光滑表面,砂砾能够在下壁面沉积,形成沉积层。这种沉积层提供了一个可吸收和分散砂砾冲击力的缓冲区域,减少了砂砾与通道壁之间的直接接触,因此,有效降低了输砂通道内下壁面的摩擦和磨损,延长了通道的使用寿命。该沉积层还可以减少输砂通道内下壁面的应力集中,提高抗打击能力,保护通道的完整性。
