Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, specifically referring to a material backflow prevention device based on belt ramp conveyor. Background Technology

[0002] In belt conveyor systems, especially in scenarios handling lumpy or spherical materials (such as electrolyte crushing systems in aluminum plant assembly workshops), existing belt conveyor devices have significant drawbacks on ramp sections: due to the lack of an effective check mechanism, materials are prone to reverse rolling under the combined effects of gravity and the belt's inclination angle. This can cause materials to not only fall back to the bottom of the belt but also potentially spill outside the belt. This problem directly affects the continuity and efficiency of material transport, and the spilled material requires manual cleanup, significantly increasing the workload for employees. Furthermore, material accumulation can lead to potential equipment malfunctions. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing belt conveyor systems when conveying blocky or spherical materials on ramps, such as material reversal, falling, and high labor intensity. This invention provides a new type of belt ramp anti-reverse grid that enables stable unidirectional material conveying, reduces labor intensity, and improves equipment operational stability.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes a material check device based on belt ramp conveying, including fixed brackets that are vertically fixed on both sides of the belt ramp. The upper end of the fixed bracket is equipped with a bearing seat, and a rotating shaft is connected between the two bearing seats. The two sets of fixed brackets are vertically connected by a limiting rod. A check grid is assembled on the rotating shaft and is parallel to the fixed bracket.

[0005] Furthermore, the limiting rod is located on the reverse movement side of the check gate, restricting the check gate to rotate only in the material transport direction.

[0006] Furthermore, the check gate is composed of several rods, the length of which is adapted to the inclination of the belt.

[0007] Furthermore, the fixing bracket is fixed to the edge of the belt ramp by bolts or welding to ensure the stability of its relative position with the belt.

[0008] The beneficial effects of this utility model by adopting the above structure are as follows:

[0009] 1. It completely solves the problem of reverse rolling of block and spherical materials on the belt ramp section, realizes stable one-way material conveying, and ensures the continuity of conveying work;

[0010] 2. Prevents materials from falling to the ground or outside the conveyor belt, eliminating the need for manual cleaning, significantly reducing the labor intensity of employees and reducing manpower input;

[0011] 3. Reduce abnormal wear and jamming of belts caused by material rollback, and improve the operational stability and service life of belts and related equipment;

[0012] 4. The check gate with multi-segment setting and height adjustment design enhances the versatility of the device, can adapt to the conveying needs of materials of different sizes, and has a wider range of applications. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1:

[0020] As per the instruction manual Figure 1-3As shown (the dashed line represents the belt conveyor), a material check device based on belt ramp conveying includes fixed brackets 1 vertically fixed to both sides of the belt ramp. The fixed brackets 1 are fixed to the edge of the belt ramp by bolts or welding to ensure the stability of the relative position with the belt. A bearing seat 2 is installed at the upper end of the fixed bracket 1, and a rotating shaft 3 is connected between the two bearing seats 2. The two sets of fixed brackets 1 are vertically connected by limiting rods 4. A check grid 5 is mounted on the rotating shaft 3 and is parallel to the fixed bracket 1. The check grid 5 is composed of several rods, the length of which is adapted to the inclination of the belt. The limiting rods 4 are located on the reverse movement side of the check grid 5. Their length and position are designed to restrict the check grid 5 to rotate only in the direction of material transportation (i.e., tilting in front of the belt conveyor) and not in the opposite direction (behind the belt conveyor), thus forming a one-way check barrier.

[0021] In a specific implementation of this utility model, when the material on the belt moves along the conveying direction and contacts the check gate 5, the thrust of the material can push the check gate 5 and the rotating shaft 3 to rotate above the bearing seat 2. The check gate 5 is pushed open along the conveying direction, allowing the material to pass smoothly. If the material attempts to roll backward due to gravity or other factors, the check gate 5 will be blocked by the limiting rod 4 and cannot rotate backward, thereby preventing the material from rolling back and avoiding it from falling to the bottom or outside of the belt.

[0022] To address the need for conveying materials of different sizes on the same belt, multiple check rails 5 can be installed along the belt length. By adjusting the vertical height of each check rail 5 relative to the belt surface (e.g., by adjusting the installation height of the fixed bracket 1 or the assembly position of the shaft 3 in the bearing seat 2), the gap between the bottom of the check rail 4 and the belt can be adapted to the maximum size of the corresponding material, ensuring that materials of different sizes can be effectively blocked from rolling backwards without affecting forward conveying.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
