Description

Technical Field

[0001] This utility model relates to the technical field of protective equipment for conveyors, specifically to a protective fence structure for a chain conveyor. Background Technology

[0002] Chain conveyors are widely used in various industries such as mining, chemical, food processing, and warehousing and logistics. In actual operation, chain conveyors typically require continuous operation for extended periods in diverse environments, sometimes operating in open or semi-open conditions, such as material transfer in open-pit mines or outdoor cargo transport in large warehousing parks. To ensure stable operation, prevent material falls that could cause accidents, and prevent external debris from entering the conveyor and affecting its normal operation, protective fencing structures are usually installed on both sides of the conveyor belt.

[0003] Most existing protective fences lack effective rainproof and drainage structures. During rainy weather, rainwater can easily wash away the fences and seep into the conveyor, causing metal parts to rust and corrode, shortening the equipment's lifespan, and potentially affecting the conveyor belt's friction coefficient, increasing the risk of slippage. Secondly, in high-temperature outdoor working environments during summer, strong direct sunlight can raise the internal temperature of the conveyor. This accelerates the aging of rubber components such as the conveyor belt, reducing their lifespan. Furthermore, the high temperature environment can cause materials to overheat during transport, leading to subsequent deterioration and mold growth. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a protective fence structure for a chain conveyor, comprising two main protective plates disposed on both sides of the conveyor belt. A positioning groove is provided on the top of each main protective plate. A water guide plate is disposed above the main protective plate; the water guide plate is an arc-shaped plate with a higher center and lower ends. Connecting blocks are fixed to the bottom ends of the water guide plate, and positioning blocks that can be inserted into the positioning grooves are fixed to the bottom of the connecting blocks. The two ends of the water guide plate extend to the sides of the two main protective plates. Two upright plates are fixed to the top ends of the water guide plate, and a sunshade is fixed to the top of each upright plate. The sunshade is an arc-shaped plate with a lower center and higher ends, and a water drop groove is provided through the center of the sunshade. A water outlet groove is provided at the end of the upright plate near the water guide plate. A lifting plate is provided to increase the height of the water guide plate. A bottom block that can be inserted into the positioning groove of the main protective plate is fixed to the bottom of the lifting plate, and a top groove for the positioning blocks of the water guide plate to be inserted into is provided on the top of the lifting plate.

[0005] Furthermore, horizontal vents are provided through the uprights to promote air circulation.

[0006] Furthermore, a reinforcing plate is fixed to the outer wall of the lifting plate, extending below the lifting plate to enhance the wind resistance of the lifting plate and its connected components. The reinforcing plate also covers the gaps at the joints to enhance waterproof performance.

[0007] Furthermore, a wind-resistant plate is fixed to the outer wall of the connecting block, and the wind-resistant plate extends to the bottom of the connecting block.

[0008] Furthermore, the water guide plate, upright plate, and sunshade plate are made of modified PP plastic sheets.

[0009] The beneficial effects of this utility model are as follows: 1. A complete rainproof and drainage system is constructed through the coordinated action of water guide plates, sunshades, drainage channels, and outlet channels. During rainy operations, rainwater is guided to the water guide plates through the drainage channels of the sunshades and the outlet channels of the uprights, and then discharged to the outside of the conveyor, achieving orderly drainage and effectively preventing rainwater from splashing around the conveyor. At the same time, the reinforcement plates and wind-resistant plates covering the joint gaps further prevent rainwater from seeping in from the joints.

[0010] 2. The lifting plate design allows the height of the protective fence to be adjusted according to the actual height of the materials being transported, without requiring modifications to the overall structure of the protective fence. When transporting lower materials, the water guide plate can be directly installed on the main protective plate; when transporting higher materials, simply adding a lifting plate will achieve the desired height.

[0011] 3. The addition of reinforcing and wind-resistant panels enhances the strength of the connections between components, while the vents in the uprights reduce the lateral pressure of strong winds on the protective fence. The sunshade effectively blocks direct sunlight, and combined with the ventilation function of the uprights, it creates a good shading and cooling effect. During high-temperature outdoor operations in summer, this prevents rubber components such as conveyor belts from aging prematurely due to high temperatures and also reduces the internal temperature of the transported materials.

[0016] The present invention will be further described below with reference to the accompanying drawings: A protective fence structure for a chain conveyor, such as Figure 1 and Figure 2 As shown, the system includes two main protective plates 1 located on both sides of the conveyor belt. A positioning groove is provided on the top of each main protective plate 1. A water guide plate 2 is located above the main protective plate 1. The water guide plate 2 is an arc-shaped plate with a higher center and lower ends. Connecting blocks 3 are fixed to the bottom ends of the water guide plate 2. A positioning block 4, which can be inserted into the positioning groove, is fixed to the bottom of the connecting blocks 3. The two ends of the water guide plate 2 extend to the sides of the two main protective plates 1. Two upright plates 5 are fixed to the top ends of the water guide plate 2. A sunshade plate 6 is fixed to the top of the upright plates 5. The sunshade plate 6 is an arc-shaped plate with a lower center and higher ends. A water drop trough 61 is provided through the middle of the sunshade plate 6. A water outlet trough 51 is provided at the end of the upright plate 5 closest to the water guide plate 2. A lifting plate 7 is provided to increase the height of the water guide plate 2. A bottom block 8, which can be inserted into the positioning groove of the main protective plate 1, is fixed to the bottom of the lifting plate 7. A top groove is provided on the top of the lifting plate 7 for the positioning block 4 of the water guide plate 2 to be inserted into.

[0017] like Figure 1 and Figure 2 As shown, in this embodiment, the upright plate 5 has a horizontally penetrating air hole 52 to promote air circulation; the outer wall of the lifting plate 7 is fixed with a reinforcing plate 9, which extends to the bottom of the lifting plate 7 to enhance the wind resistance of the lifting plate 7 and its connecting parts, and the reinforcing plate 9 covers the gap at the connection to enhance the waterproof performance; the outer wall of the connecting block 3 is fixed with a wind-resistant plate 10, which extends to the bottom of the connecting block 3.

[0018] In this embodiment, the water guide plate 2, the upright plate 5, and the sunshade plate 6 are modified PP plastic plates.

[0019] The working principle of this utility model is as follows: The main protective plate 1 is firmly connected to the conveyor frame or ground foundation by the expansion bolts at the bottom, forming a vertical protective barrier. It can effectively prevent materials from falling from both sides of the conveyor belt during material transmission, and at the same time prevent external personnel, tools or debris from entering the conveyor, avoiding collisions with the moving parts of the conveyor, and ensuring the normal operation of the conveyor and the personal safety of the operators.

[0020] When working in rainy conditions, the sunshade 6, with its arc-shaped structure (lower in the middle and higher at both ends), allows rainwater to converge towards the center under gravity and flow into the drainage trough 61 located in the middle. The rainwater then falls onto the guide plate 2, which also features an arc-shaped structure (higher in the middle and lower at both ends). Rainwater flowing onto the guide plate 2 then travels along its curved surface towards both ends, eventually exiting through the drainage channel 51 on the vertical plate 5. Since the guide plate 2 extends to the sides of the main protective plate 1, the rainwater is ultimately discharged from both ends to the ground away from the conveyor, achieving orderly drainage and effectively preventing splashing around the conveyor. Simultaneously, the reinforcing plates 9 on the outer wall of the lifting plate 7 and the wind-resistant plates 10 on the outer wall of the connecting block 3 cover the gaps at their respective connections, preventing rainwater from seeping in and further enhancing the waterproof performance of the entire protective fence.

[0021] In high-temperature outdoor working conditions during summer, the sunshade 6 can completely cover the area of ​​the conveyor belt and the main protective plate 1 below. When the sun is shining directly, the sunshade 6 can block most of the sunlight, preventing it from directly hitting the conveyor belt, rollers, and electrical control system components, thus reducing the ambient temperature inside the conveyor. At the same time, the vents 52 on the upright plate 5 can promote air circulation between the inside and outside of the protective fence. The heat generated during the operation of the conveyor can be dissipated into the external environment in a timely manner through the vents 52, further reducing the temperature inside the protective fence and creating a good ventilation and heat dissipation effect.

[0022] When the height of the protective fence needs to be adjusted according to the height of the transported material, it can be adjusted using the lifting plate 7. If the height of the transported material is low, and there is no need to increase the height of the protective fence, the positioning block 4 on the bottom connecting block 3 of the water guide plate 2 can be directly inserted into the positioning groove at the top of the main protective plate 1, so that the water guide plate 2 is directly installed on the main protective plate 1. If the height of the transported material is high, and the height of the protective fence needs to be increased, first insert the bottom block 8 of the lifting plate 7 into the positioning groove at the top of the main protective plate 1, and then insert the positioning block 4 of the bottom of the water guide plate 2 into the top groove at the top of the lifting plate 7 to complete the connection between the water guide plate 2 and the lifting plate 7 (the appropriate number of lifting plates 7 can also be stacked according to the actual situation). With the addition of the lifting plate 7, the overall height of the protective fence is increased by the height of the lifting plate 7, thereby meeting the protection requirements of higher materials. The installation and disassembly of the lifting plate 7 are simple and do not require structural modification of the main protective plate 1 and the water guide plate 2.

[0023] In the event of severe weather such as strong winds, the air vents 52 on the upright plate 5 can reduce the lateral pressure of strong winds on the protective fence. Strong winds can pass through the protective fence through the air vents 52, reducing wind resistance and preventing the protective fence from tilting or deforming due to excessive lateral wind force. Secondly, the reinforcing plate 9 on the outer wall of the lifting plate 7 not only enhances the strength of the connection between the lifting plate 7 and the main protective plate 1, but also improves the stability of the connection by tightly fitting the part extending below the lifting plate 7 with the main protective plate 1. Similarly, the wind-resistant plate 10 on the outer wall of the connecting block 3 can also enhance the strength of the connection between the connecting block 3 and the main protective plate 1 or the lifting plate 7, reducing the impact of strong winds on the connection.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
