Description

Cleaning device for chute of ship loader Technical Field The invention relates to the technical field of ship loaders, in particular to a cleaning device for a chute of a ship loader. Background The top of the chute is communicated with the tail of a material conveying belt on the ship loader, and the material moves downwards from the chute after leaving the conveying belt, so that the problem of dust dissipation in the powder loading and unloading process is mainly solved. The chute is generally of a telescopic structure so that the bottom of the chute is close to the bottom of the fork. The telescopic chute is generally formed by combining a canvas cover and a supporting ring. When different bulk cargoes pass through the chute, a part of the cargoes can remain on the canvas. If the chemical or grain particulates mix, the cargo may react during transportation or storage, causing damage or failure of the material. In cleaning tubular spaces, the interior of the tubular pile space is typically cleaned by rotating the brush. When the chute is longer, the device for controlling the rotary brush through the traction rope is required to move in the chute, if a rigid connecting rod is used, the device for controlling the rotary brush can be easily broken, and the tubular space can be cleaned by moving up and down through the traction rope. However, the rotation of the device of the rotary brush is easy to cause when the device of the rotary brush works, and the traction rope is wound and knotted, so that the device cannot be kept in a relatively stable state with the pipe wall, and the cleaning effect or the stability of the structure of the device can be influenced, so that the chute cleaning device needs to be optimized. Disclosure of Invention Aiming at the defects existing in the prior art, the invention provides a cleaning device for a chute of a ship loader, which solves the problem that the device for controlling the rotary brushing device is easy to cause autorotation when the length of the chute is longer in the prior art. According to the embodiment of the invention, the cleaning device is arranged in the chute of the ship loader and comprises a first motor, a second motor, a movable frame, a first traction rope, more than two annular brushes and a transmission assembly, wherein the top of the chute is upwards raised and higher than the position communicated with the ship loader body, the movable frame is of a cylindrical structure, the movable frame is arranged in the chute and is coaxial, the first motor is horizontally and fixedly arranged at the top of the chute, one end of the first traction rope is fixedly connected with an output shaft of the first motor, the other end of the first traction rope downwards extends to the center of gravity of the movable frame and is correspondingly and fixedly connected with the center of gravity of the movable frame, the annular brushes are sleeved outside the movable frame and are in rotary connection with the movable frame, the transmission assembly is fixedly arranged with a second single machine and the annular brushes, and the second motor is connected with the annular brushes through the transmission assembly so that the annular brushes simultaneously rotate in the forward and reverse directions. The invention has the technical principle that when the movable frame moves up and down in the chute, the second motor drives more than two annular brushes to rotate in opposite directions to clean the chute, and the reaction force of the chute to the annular brushes can be counteracted by the opposite rotating force, so that the condition of autorotation of the movable frame is avoided. Preferably, the transmission assembly comprises a first gear, a fixed ring is fixedly arranged in the annular brush, annular teeth are arranged on the end faces of adjacent fixed rings, an interval is arranged between adjacent annular teeth, the first gear is horizontally arranged between two adjacent annular teeth and meshed with the two annular teeth at the same time, and the end part of the first gear is rotationally connected with the movable frame. Preferably, the second motor is vertically and fixedly arranged inside the movable frame, a second gear is arranged on an output shaft of the second motor, an inner gear is arranged on the inner side of one fixed ring, and the second gear is meshed with the inner gear. When the second motor rotates, one of the fixing rings is driven to rotate, and the adjacent fixing rings rotate in opposite directions. The telescopic device is characterized by further comprising a third gear, a telescopic rod, a rotating shaft, a fan blade and two sealing plates, wherein the telescopic rod is vertically arranged and fixedly connected with the movable frame, the gear is vertically arranged on the outer wall of the rotating shaft, the rotating shaft and the telescopic rod are coaxial and are rotationally connected with the movable section of the tele
