Description

Technical field:

[0001] The utility model belongs to the technical field of port cranes, and in particular relates to a dock material recovery device with a bucket crane. Background technology:

[0002] A gantry crane is a lifting machine used for unloading bulk cargo at bulk terminals. Materials are transported via a grab bucket into the gantry crane's hopper, where they are then transferred via a conveyor belt to the storage yard or other material handling machinery. During this process, materials can inevitably accumulate and spill due to environmental factors and various human factors. To improve unloading efficiency, the grab bucket is typically unloaded from the transport vessel into the gantry crane's hopper near the dock's docking station. Furthermore, to maximize the conveyor belt's efficiency, the unloading conveyor is often located close to the seaside of the terminal. This further increases the risk of the gantry crane dropping material into the water at the seaside gantry legs.

[0003] In addition, the belt conveyor unloading system with a bucket door mainly uses a material guide chute and a rubber curtain at the end to adjust the material transportation path so that the material can smoothly fall on the appropriate position on the belt conveyor. However, the existing belt conveyor system has a simple receiving port structure and limited sealing, which may cause the material to spill or overflow from the head of the belt conveyor. Figure 1 shown.

[0004] Therefore, in order to reduce the waste of raw materials and environmental problems caused by the spillage of materials during the unloading process, the utility model proposes a dock material recovery device with a bucket gate crane to solve the above problems. Summary of the invention:

[0005] The purpose of the utility model is to provide a material recovery device for a dock with a bucket gate crane in view of the deficiencies in the existing technology, which solves the problem that the original unloading of the bucket gate crane easily causes material falling, resulting in waste of resources and environmental pollution.

[0006] The utility model adopts the following technical solutions:

[0007] The utility model provides a material recovery device for a dock with a bucket gate crane, comprising a material blocking device, which is installed on a door leg of the dock with a bucket gate crane and is distributed below a material receiving port of a belt conveyor system.

[0011] Furthermore, the material blocking device also includes a material blocking plate angle adjustment mechanism; the material blocking plate angle adjustment mechanism includes a winch, a redirecting roller and a traction rope; the winch is fixedly installed on the bucket door machine, and the redirecting roller is installed on the door leg of the bucket door machine. One end of the traction rope is fixed on the winch, and the other end is connected to the material blocking plate through the redirecting roller.

[0012] Furthermore, a roller support is provided on the door leg of the bucket door machine, and the redirecting roller is installed on the roller support.

[0013] Furthermore, the material blocking device also includes a safety rope, one end of which is connected to the steel structure of the bucket door machine, and the other end is connected to the material blocking plate.

[0014] Furthermore, a material recovery box is provided below the baffle plate, and the material recovery box is fixedly mounted on the door leg of the bucket door machine.

[0015] Furthermore, the device is also provided with a material guiding plate, which is distributed between the material blocking plate and the blanking recovery box.

[0016] Furthermore, the material guide plate is arranged at an angle, with one end fixedly connected to the blanking recovery box and the other end fixedly connected to the door leg of the bucket door machine.
