Description

Technical Field

[0001] This utility model relates to the field of port equipment technology, specifically to a material receiving hopper device for port operations. Background Technology

[0002] Port receiving hoppers are port equipment used to assist in loading and unloading cargo. They are used to handle small particles such as sand and gravel, and mainly serve to prevent leakage and waste during cargo loading and unloading, making it easier for port machinery to better place cargo onto transfer vehicles and improve loading and unloading efficiency.

[0003] Most existing receiving hoppers are fixed with vertical rods. However, when receiving materials for a long time, the impact and gravity of the material on the receiving hopper can easily cause the hopper to deform. At the same time, the receiving hopper will cause serious dust diffusion when discharging materials. Therefore, a receiving hopper device for port operations is proposed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a receiving hopper device for port operations to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a receiving hopper device for port operations, comprising a receiving hopper, wherein a dust suppression component is provided at the bottom of the receiving hopper;

[0006] Each of the four sets of support columns is fixed with a support column at the external corner. The lower end of the curved outer wall of the four sets of support columns is fixed with a first crossbar near the front and rear sides of the receiving hopper. The top of the first crossbar is fixed with a first crossbar. The middle end of the curved outer wall of the four sets of support columns is fixed with a second crossbar near the left and right sides of the receiving hopper. The top of the second crossbar is fixed with a second crossbar.

[0007] The dust suppression component includes a connecting frame fixed to the bottom of the receiving hopper. Hydraulic cylinders are installed on both sides inside the connecting frame. A horizontal plate is fixed to the end of the hydraulic cylinder. An oil storage tank is provided at the top of the horizontal plate inside the connecting frame. A multi-stage telescopic sleeve is fixed to the inner wall of the connecting frame.

[0008] As a preferred technical solution, the bottom of the receiving hopper is provided with a discharge port, and a valve switch for controlling the discharge from the discharge port is installed on one side of the lower end of the receiving hopper.

[0009] As a preferred technical solution, the ends of both the first and second cross rods are fixed to the support column.

[0010] As a preferred technical solution, a ladder for personnel to climb is installed at the rear end of the receiving hopper.

[0011] As a preferred technical solution, multiple sets of connecting pipes are provided between the multi-stage telescopic sleeve and the oil storage tank, and an oil inlet groove is opened between the multi-stage telescopic sleeves.

[0012] As a preferred technical solution, the multi-stage telescopic sleeve is connected to the discharge port.

[0013] In summary, the present invention has the following main advantages:

[0014] 1. The present invention uses a triangular support structure formed by the first and second cross rods distributed around the receiving hopper, which can effectively resist vibration and impact in both horizontal and vertical directions, improve the deformation resistance of the receiving hopper, and disperse local stress throughout the entire support frame to avoid stress concentration leading to metal fatigue of the receiving hopper.

[0015] 2. This utility model activates the hydraulic cylinder and pushes the horizontal plate to move inside the oil storage tank, so that the oil inside the oil storage tank enters the multi-stage telescopic sleeve and the oil inlet through the connecting pipe. The multi-stage telescopic sleeve extends from inside the connecting frame, which can effectively reduce the height of the material when it is unloaded. As a result, when the material falls into the vehicle, the suction effect of the falling airflow on the surrounding air can be significantly reduced, greatly reducing the range of dust diffusion.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] A material receiving hopper device for port operations, such as Figure 1-4 As shown, it includes a receiving hopper 100, and a dust suppression component 200 is provided at the bottom of the receiving hopper 100;

[0025] Support columns 120 are fixed at the external corners of the receiving hopper 100. First crossbars 130 are fixed at the lower ends of the curved outer walls of the four sets of support columns 120 near the front and rear sides of the receiving hopper 100. First crossbars 140 are fixed at the top of the first crossbars 130. Second crossbars 150 are fixed at the middle ends of the curved outer walls of the four sets of support columns 120 near the left and right sides of the receiving hopper 100. Second crossbars 160 are fixed at the top of the second crossbars 150.

[0026] The dust suppression component 200 includes a connecting frame 210 fixed to the bottom of the receiving hopper 100. Hydraulic cylinders 220 are installed on both sides inside the connecting frame 210. A horizontal plate 230 is fixed to the end of the hydraulic cylinder 220. An oil storage tank 231 is provided at the top of the horizontal plate 230 inside the connecting frame 210. A multi-stage telescopic sleeve 240 is fixed to the inner wall of the connecting frame 210. A multi-stage telescopic sleeve 240 is provided between the multi-stage telescopic sleeve 240 and the oil storage tank 231. An oil inlet groove 251 is provided between the multi-stage telescopic sleeve 240.

[0027] By unloading materials from the port into the receiving hopper 100, vehicles can drive under the receiving hopper 100 for loading, as the second crossbar 150 is located at the end of the support column 120. The triangular support structure formed by the first crossbar 140 and the second crossbar 160, distributed around the receiving hopper 100, effectively resists horizontal and vertical vibrations and impacts simultaneously, improving the deformation resistance of the receiving hopper 100. It also disperses local stress throughout the support frame, preventing stress concentration that could lead to metal fatigue in the receiving hopper 100, thus facilitating material unloading. At that time, by activating the hydraulic cylinder 220 and pushing the horizontal plate 230 to move inside the oil storage tank 231, the oil inside the oil storage tank 231 enters the multi-stage telescopic sleeve 240 and the oil inlet 251 through the connecting pipe 250. As the horizontal plate 230 continues to move, the multi-stage telescopic sleeve 240 can extend out from inside the connecting frame 210. Through the movement of the multi-stage telescopic sleeve 240, the height of the material being discharged can be effectively reduced, thereby significantly reducing the suction effect of the falling airflow on the surrounding air when the material falls into the vehicle, and greatly reducing the range of dust diffusion.

[0028] Please refer to this carefully. Figure 2 The bottom of the receiving hopper 100 is provided with a discharge port 110, and a valve switch 111 for controlling the discharge of material from the discharge port 110 is installed on one side of the lower end of the receiving hopper 100.

[0029] By controlling the valve switch 111, the material inside the receiving hopper 100 can be transferred from the discharge port 110 to the vehicle, facilitating unloading.

[0030] Please refer to this carefully. Figure 1 The ends of the first cross bar 140 and the second cross bar 160 are fixed to the support column 120, and a ladder 170 for personnel to climb is installed at the rear end of the receiving hopper 100.

[0031] The ladder 170 allows staff to easily climb and observe the material inside the receiving hopper 100.

[0032] Please refer to this carefully. Figure 3 and Figure 4 The multi-stage telescopic sleeve 240 is connected to the discharge port 110.

[0033] By connecting the multi-stage telescopic sleeve 240 to the discharge port 110, the material inside the receiving hopper 100 can pass through more effectively.

[0034] In use, the triangular support structure formed by the first cross bar 140 and the second cross bar 160 is distributed around the receiving hopper 100, which can effectively resist horizontal and vertical vibration and impact at the same time, improve the deformation resistance of the receiving hopper 100, and also disperse local stress throughout the entire support frame, avoiding stress concentration that could lead to metal fatigue of the receiving hopper 100. When discharging material, the hydraulic cylinder 220 is activated and the horizontal plate 230 is pushed to move inside the oil storage tank 231, so that the oil inside the oil storage tank 231 enters the multi-stage telescopic sleeve 240 and the oil inlet 251 through the connecting pipe 250, and the multi-stage telescopic sleeve 240 extends out from inside the connecting frame 210, which can effectively reduce the height of material discharge, thereby significantly reducing the suction effect of the falling airflow on the surrounding air when the material falls into the vehicle, and greatly reducing the range of dust diffusion. The parts of this device not mentioned are the same as or can be implemented using existing technology.
