Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass production technology, and more specifically, it relates to an anti-overflow device for the discharge port of a sand rake. Background Technology
[0002] Glass manufacturers often pile up silica sand high when storing it. During the operation of the sand rake, the silica sand falls from this height and, under gravity, crashes heavily onto the conveyor belt below the machine's feed inlet. This causes some material to overflow from the gap between the feed inlet and the conveyor belt, increasing the workload for production staff in cleaning up the spilled material and wasting resources.
[0003] Existing technology includes a device titled "A Silica Sand Storage and Feeding Device" with publication number CN119873414A. This device comprises a storage silo, an internal sand-raking machine, a grab bucket bridge crane above the silo, a sand pile to the left of the sand-raking machine inside the silo, a feeding conveyor belt at the top of the silo, a discharge collection conveyor belt below the sand-raking machine inside the silo, and a drainage ditch at the bottom of the silo. A storage and feeding control system is also included inside the silo. This silica sand storage and feeding device uses a sand-raking machine, a movable support, pulley blocks, wire ropes, a drainage ditch, and a support drive motor. The feeding conveyor belt transports silica sand into the storage silo. Moisture inside the silica sand seeps downwards into the drainage ditch and is then discharged. The sand-raking machine is activated, transporting the silica sand above the sand pile to the discharge collection conveyor belt for easy discharge.
[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a simple structure for preventing material from overflowing from the conveying component when it falls on the conveying component, thereby reducing material waste, avoiding frequent cleaning by operators of material overflowing to the ground near the conveying component, and reducing the amount of cleaning work.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] This utility model is a material overflow prevention device for the discharge port of a sand rake. A discharge port is provided at the bottom of the hopper, and a conveying component is provided below the discharge port. Each side of the lower part of the discharge port is provided with a material overflow prevention plate. The outer side of each material overflow prevention plate is connected to the outside of the discharge port, and the inner side of each material overflow prevention plate extends to the inside of the discharge port. The material overflow prevention plate is designed with a downwardly concave arc-shaped surface structure.
[0008] The silo is fixed on the support frame, a feeding channel is set above the silo, a rake chain is set on the feeding channel, and a sand rake is also set above the silo.
[0009] The conveying component is a ring conveyor belt, which is mounted on a drive roller and a driven roller. The drive roller is connected to a drive motor.
[0010] The anti-overflow plate includes a first anti-overflow plate and a second anti-overflow plate, which are arranged symmetrically.
[0011] A first bracket is welded to the outside of one side of the discharge port, and a first anti-overflow plate is connected to the first bracket by bolts. A second bracket is welded to the outside of the other side of the discharge port, and a second anti-overflow plate is connected to the second bracket by bolts.
[0012] The conveying component is provided with an intermediate bearing roller, a first bearing roller, and a second bearing roller at its lower part. The intermediate bearing roller is located below the upper layer of the conveyor belt of the conveying component and is arranged horizontally. The first bearing roller is located on one side of the intermediate bearing roller and the second bearing roller is located on the other side of the intermediate bearing roller.
[0013] The spill-proof plate is made of a flexible material.
[0014] The outer side of the first bearing roller of the conveying component is inclined upward, the outer side of the second bearing roller is inclined upward, and the upper layer of the conveyor belt has a U-shaped structure.
[0015] A first reinforcing rib is provided between the first support and the outside of the discharge port, and a second reinforcing rib is provided between the second support and the outside of the discharge port.
[0016] The working principle and beneficial effects of this utility model are as follows:
[0017] The anti-overflow device for the sand rake's discharge port of this utility model is structurally designed with a discharge port at the bottom of the hopper. The hopper and discharge port are an integrated structure, with the hopper having a funnel-shaped opening and the discharge port having a square shape. Material enters the hopper from the larger opening at the top and exits through the discharge port at the bottom. The material falling from the discharge port lands on a conveying component, which continuously transports the material. Anti-overflow plates are installed on each side of the lower part of the discharge port. The outer side of each anti-overflow plate connects to the outside of the discharge port, and the inner side of each anti-overflow plate extends into the inside of the discharge port. The anti-overflow plates are designed with a downwardly concave arc-shaped surface. When material falls, material in the middle lands directly on the conveying component, material on one side lands first on the anti-overflow plate on that side, and material on the other side lands first on the anti-overflow plate on the other side, and so on. Materials are conveyed via a continuous conveyor system, preventing spillage. The system moves continuously during transport, ensuring constant material delivery. Anti-overflow plates on both sides, in conjunction with the conveyor system, completely enclose the material from below, reducing the amount of silica sand that spills onto the conveyor and minimizing the workload of frequent cleanup.

[0022] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0023] As attached Figure 1 Appendix Figure 2As shown, this utility model is an anti-overflow device for the discharge port of a sand rake. A discharge port 2 is located at the lower part of the hopper 1, and a conveying component 3 is located below the discharge port 2. Anti-overflow plates 4 are respectively installed on each side of the lower part of the discharge port 2. The outer side of each anti-overflow plate 4 connects to the outside of the discharge port 2, and the inner side of each anti-overflow plate 4 extends to the inside of the discharge port 2. The anti-overflow plate 4 is designed with a downwardly concave arc-shaped surface structure. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this configuration, the discharge port 2 is located at the lower part of the hopper 1, and the hopper 1 and discharge port 2 are an integrated structure. The hopper 1 has a funnel-shaped opening, and the discharge port 2 has a square structure. The hopper 1 receives material from the larger opening at the top, and the material in the hopper 1 discharges from the lower discharge port 2. The material falling from the discharge port 2 lands on the conveying component 3, and the continuously moving conveying component 3 ensures continuous material transport. Anti-overflow plates 4 are installed on each side of the lower part of the discharge port 2. The outer side of each anti-overflow plate 4 is connected to the outside of the discharge port 2, and the inner side of each anti-overflow plate 4 extends to the inside of the discharge port 2. The anti-overflow plate 4 is designed with a downwardly concave arc-shaped surface structure. When the material falls, the material in the middle falls directly onto the conveying component 3, while the material on one side falls onto the anti-overflow plate 4 on that side first, and not directly onto one side of the conveying component 3. The material on the other side falls onto the anti-overflow plate 4 on the other side first, and not directly onto the other side of the conveying component 3. The material is conveyed by the conveying component 3 without overflowing. The conveying component 3 moves continuously while conveying the material, achieving continuous material conveying. Through the anti-overflow plates 4 on both sides, in conjunction with the conveying component 3, the material is fully wrapped from below, reducing the overflow of silica sand material from the outside when it falls onto the conveying component 3, and reducing the workload of employees who need to frequently clean up the overflowing material. The anti-overflow device at the discharge port of the sand rake described in this utility model has a simple structure and can prevent the material from overflowing to the outside of the conveying component when it falls on the conveying component, thereby reducing material waste and avoiding the need for operators to frequently clean up the overflow that falls to the ground near the conveying component, thus reducing the amount of cleaning work.
[0024] The hopper 1 is fixed on a support frame. A feeding channel 5 is provided above the hopper 1, and a rake chain 6 is installed on the feeding channel 5. A sand rake 7 is also installed above the hopper 1. In this structure, the feeding channel 5 is used for stockpiling material, while the sand rake 7 and rake chain 6 are used to feed the material on the stockpiling channel into the hopper, realizing the discharge of material from the discharge port. The technical improvement of this utility model mainly lies in adding an anti-overflow device to the discharge port, and does not involve any structural improvement to the sand rake 7 and rake chain 6. Therefore, the sand rake 7 and rake chain 6 are mature structures that already exist in the prior art.
[0025] The conveying component 3 is a ring-shaped conveyor belt, which is mounted on a drive roller and a driven roller. The drive roller is connected to a drive motor. This structure, through the drive motor driving the drive roller to rotate, drives the conveyor belt of the conveying component, enabling continuous movement of the conveyor belt and conveying of materials. The lower part of the conveying component 3 is equipped with an intermediate support roller 12, a first support roller 13, and a second support roller 14. The intermediate support roller 12 is located below the upper layer of the conveyor belt of the conveying component 3 and is horizontally arranged. The first support roller 13 is located on one side of the intermediate support roller 12, and the second support roller 14 is located on the other side. In this structure, the intermediate support roller 12, the first support roller 13, and the second support roller 14 are mainly used to support the conveyor belt, making the entire conveyor belt have a U-shaped structure, which can reliably support materials and prevent material spillage. Combined with the structure of the anti-overflow device at the discharge port, this further effectively prevents material spillage.
[0026] The anti-overflow plate 4 includes a first anti-overflow plate 8 and a second anti-overflow plate 9, which are symmetrically arranged. This structure, through the arrangement of the first anti-overflow plate 8 and the second anti-overflow plate 9, prevents material from overflowing from both sides.
[0027] A first bracket 10 is welded to the outside of one side of the discharge port 2, and a first anti-overflow plate 8 is bolted to the first bracket 10. A second bracket 11 is welded to the outside of the other side of the discharge port 2, and a second anti-overflow plate 9 is bolted to the second bracket 11. The anti-overflow plate 4 is made of an elastic material. In the above structure, the first bracket 10 connects the first anti-overflow plate 8, and the second bracket 11 connects the second anti-overflow plate 9. The inner side of the first anti-overflow plate 8 is located inside the discharge port 2, reliably bearing the material. When the material is discharged from the hopper 1, the weight of the material causes the first anti-overflow plate 8 to move downwards, thus approaching the upper part of the conveyor belt of the conveying component, making the gap between the upper layer of the conveyor belt and the first anti-overflow plate 8 extremely small, reliably preventing material overflow. Similarly, when the material is discharged from the hopper 1, the weight of the material causes the second anti-overflow plate 9 to move downwards, thus approaching the upper part of the conveyor belt of the conveying component 3, making the gap between the upper layer of the conveyor belt and the second anti-overflow plate 9 extremely small, reliably preventing material overflow.
[0028] The outer side of the first bearing roller 13 of the conveying component 3 is inclined upward, and the outer side of the second bearing roller 14 is also inclined upward, forming a U-shaped structure on the upper layer of the conveyor belt. This structure, with the first bearing roller 13, the second bearing roller 14, and the intermediate bearing roller working together, results in a U-shaped structure on the upper layer of the conveyor belt, which helps to gather materials falling onto the upper surface of the conveyor belt of the conveying component.
[0029] A first reinforcing rib 15 is provided between the first support 10 and the outside of the discharge port 2, and a second reinforcing rib 16 is provided between the second support 11 and the outside of the discharge port 2. In this structure, the first reinforcing rib 15 effectively improves the connection strength between the first support 10 and the discharge port 2, and the second reinforcing rib 16 effectively improves the connection strength between the second support 11 and the discharge port 2, thereby increasing service life.
[0030] The overflow prevention device for the sand rake's discharge port of this utility model is structurally designed with a discharge port 2 at the bottom of the hopper 1. The hopper 1 and discharge port 2 are an integral structure. The hopper 1 has a funnel-shaped opening, while the discharge port 2 has a square structure. The hopper 1 receives material from the upper, wider end, and the material in the hopper 1 discharges from the lower discharge port 2. The material falling from the discharge port 2 lands on the conveying component 3, which continuously transports the material. An overflow prevention plate 4 is provided on each side of the lower part of the discharge port 2. The outer side of each overflow prevention plate 4 is connected to the outside of the discharge port 2, and the inner side of each overflow prevention plate 4 extends into the interior of the discharge port 2. The overflow prevention plate 4 is designed with a downwardly concave arc-shaped surface structure. When the material falls, material in the middle lands directly on the conveyor component 3, while material on one side first lands on the anti-overflow plate 4 on that side, preventing it from landing directly on one side of the conveyor component 3. Similarly, material on the other side lands on the anti-overflow plate 4 on the other side, preventing it from landing directly on the other side of the conveyor component 3. The conveyor component 3 continuously moves, preventing material overflow. The anti-overflow plates 4 on both sides, in conjunction with the conveyor component 3, provide comprehensive protection for the material from below, reducing the amount of silica sand that spills onto the conveyor component 3 and minimizing the workload of employees frequently cleaning up spilled material.
