Self-weighing hopper of loading and unloading device

Abstract

The invention relates to a self-weighing hopper of a loading and unloading device. The self-weight hopper is mainly characterized in that a material collecting plate is arranged at an upper hole of a hopper body of the hopper, side windshield plates are respectively fixed on both sides of an edge of the upper hole of the hopper body of the hopper, and the edge is perpendicular to a shoreline; a weighing load unit and an anti-deflexion device are both arranged under a supporting beam of the hopper body of the hopper; a rear windshield plate is arranged at the upper hole of the hopper body of the hopper; bin-wall vibrators are respectively arranged on both sides of a hopper wall without a hopper door at the middle lower part of the hopper body; a main hopper door and a secondary hopper door are respectively arranged on both sides of a discharging hole of the hopper; a vibrating motor of each bin-wall vibrator is connected with a built-in vibration plate by a motor installing bracket, the built-in vibration plate is fixed on the inner side of the hopper wall of the hopper by bolts, and a safe lifting lug and a safe chain are hung on the vibrating motor. In the invention, the weighing load unit has high precision; the structure modes of the main hopper door and the secondary hopper door avoid the phenomena of material blockage, and the like due to poor fluidity of materials; and compared with the traditional vibrating motor, the built-in vibration plate is directly arranged on the hopper wall in order to more effectively vibrate and disperse blocked materials.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and relates to an improved technology for loading and unloading equipment with a load-bearing hopper, which is mainly aimed at the load-bearing hopper equipment for unloading materials with poor fluidity. Background technique [0002] With the economic development, the port construction is advancing by leaps and bounds. The demand for loading and unloading equipment such as ship unloaders and container quay cranes is increasing. Generally, bulk materials are measured by the belt scale on the belt conveyor in the port corridor. However, since the belt scale weighs fluid materials, the accuracy is low. When it is used alone, disputes between buyers and sellers often arise on the measurement results. In this regard, the weighing hopper is generally used to weigh the material to check the accuracy of the belt scale. And because there are many kinds of materials, especially those con...

Problems solved by technology

The traditional single-side movable hopper door cannot meet the working conditions required for materials with poor fluidity. The sliding plate hopper door is not only difficult to open and close, but also has poor flow regulation ability. Equipment life, resulting in higher failure frequency and maintenance frequency, which greatly affects production efficiency
