Description

Technical Field

[0001] This utility model relates to the field of casting grinding ball production, specifically a transport device for casting grinding balls. Background Technology

[0002] Cast grinding balls are highly wear-resistant media widely used in industries such as mining, cement, thermal power generation, and metallurgy. They are mainly used in ball mills to grind materials such as ores and pulverized coal. Due to their harsh working environment, cast grinding balls are typically made of high-hardness, high-wear-resistant materials such as high-chromium cast iron and alloy steel. The weight of a single ball ranges from tens to hundreds of grams, with some large grinding balls even reaching several kilograms. After casting, the grinding balls need to undergo multiple stages, including heat treatment, surface cleaning, quality inspection, and packaging. Frequent transfers are required during this process, thus placing high demands on the stability and efficiency of the transportation equipment and the protective performance of the grinding balls.

[0003] Currently, some companies use vibrating conveyors, chain conveyors, or roller conveyors for transporting grinding balls. For example, the Chinese authorized patent (an auxiliary transport device for a wear-resistant steel ball casting production line) with announcement number CN 110201891 B uses a motor. The output of the motor rotates, which drives one of the telescopic rods to rotate, which in turn drives two pulleys to rotate. This causes the two sets of pulleys to rotate simultaneously. Then, through the rubber ropes, the rotation of the two sets of pulleys drives the rotation of two rubber ropes, thus enabling the transport of steel balls.

[0004] The aforementioned prior art uses two rubber ropes to rotate and drive the grinding balls between them. However, the grinding balls tend to roll along the conveying direction between the two rubber ropes, causing adjacent grinding balls to collide with each other, which affects the surface condition of the grinding balls during the conveying process. Utility Model Content

[0005] The purpose of this invention is to provide a transport device for casting grinding balls, in order to solve the problem mentioned in the background art that the grinding balls tend to roll along the transport direction during the transport process, causing adjacent grinding balls to collide with each other and affecting the surface condition of the grinding balls.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transport device for casting grinding balls, comprising a main transport unit, the main transport unit comprising a support platform, a first driving member and a second driving member respectively provided on both sides of the upper end of the support platform, the first driving member and the second driving member both being composed of an intermediate shaft and driving gears, each group of two driving gears being located at the front and rear ends outside the intermediate shaft, the two front driving gears and the two rear driving gears being meshed with a transmission chain, a conveyor belt being fixed to the outside of the two transmission chains, the outer surface of the conveyor belt having an array of multiple V-shaped slots, a V-shaped anti-slip strip being fixed in the V-shaped slots, each V-shaped anti-slip strip having an array of several triangular prisms fixed in the V-shaped anti-slip strip, a grinding ball conveying groove being formed inside the V-shaped anti-slip strip along the left and right adjacent triangular prisms, the grinding ball conveying groove being in the shape of a frustum of a quadrangular pyramid.

The auxiliary transport unit includes a transport platform, which is inclined towards the main transport unit. Side baffles are welded and fixed to the front and rear ends of the upper end of the transport platform.

[0009] Preferably, the upper end of the transport platform forms a loading area, a converging area, and a unloading area from left to right between the two side baffles. The loading area narrows towards the converging area and widens towards the unloading area, and the width of the converging area matches the diameter of the casting grinding ball.

[0010] Preferably, the upper end of the transport platform is provided with multiple partition plates from front to back along the area where the unloading area is located.

[0012] Preferably, support frames are welded and fixed at the four corners of the lower end of the transport platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, by setting a grinding ball conveying groove in the shape of a truncated pyramid, different sizes of grinding balls can be matched, so that each grinding ball can enter an independent grinding ball conveying groove and will not collide with each other, effectively avoiding surface damage of the grinding balls during transportation and improving product quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-5 One embodiment of this utility model is a transport device for casting grinding balls, which mainly consists of an auxiliary transport unit 1 and a main transport unit 14.

[0025] The auxiliary transport unit 1 includes a transport platform 2, which is inclined toward the main transport unit 14. This inclined design allows the grinding balls to move along the transport platform 2 under their own weight. Side baffles 3 are welded and fixed to the front and rear ends of the upper end of the transport platform 2. The side baffles 3 can prevent the grinding balls from falling off the sides of the transport platform 2 during transport, ensuring that the grinding balls move along the predetermined path of the transport platform 2.

[0026] The upper part of the transport platform 2, between the two side baffles 3, forms a loading area 4, a converging area 5, and a unloading area 6 from left to right. The loading area 4 narrows towards the converging area 5, and widens towards the unloading area 6. The width of the converging area 5 matches the diameter of the cast grinding balls, but is not exactly the same; it is slightly larger than the diameter of the larger cast grinding balls, but its width is less than 1.5 times the diameter of the smaller cast grinding balls. This is mainly to accommodate casting grinding balls of various sizes, ensuring that each ball can pass through individually while preventing jamming. This design allows the grinding balls to enter the loading area 4 in a relatively dispersed manner. As the transport platform 2 narrows, only one grinding ball is allowed to pass through the converging area 5 at a time, achieving an initial orderly arrangement of the grinding balls and providing a good foundation for subsequent transport.

[0027] Multiple partition plates 7 are arranged from front to back along the area where the unloading area 6 is located on the upper end of the transport platform 2. Multiple conveying channels 8 are formed between adjacent partition plates 7 and between partition plates 7 and side baffles 3 on the upper end of the transport platform 2. The width of the multiple conveying channels 8 is the same, and the width of the conveying channels 8 is the same as the width of the convergence area 5. The arrangement of the conveying channels 8 further standardizes the transport path of the grinding balls, enabling the grinding balls to move in an orderly manner along the predetermined channels, preparing them for entering the main transport unit 14.

[0028] A lower support 9 is welded and fixed to the lower end of the conveyor table 2 along the lower end of the unloading area 6. A first drive motor 10 is installed at the lower end of the lower support 9. A rotating disk 11 is installed on the end face of the conveyor table 2 along the output shaft end of the first drive motor 10. The rotating disk 11 is rotatably connected to the conveyor table 2 via bearings. Silicone protrusions 12 are arrayed and fixed to the upper end of the rotating disk 11. When the grinding balls reach the upper end of the rotating disk 11 located in the unloading area 6, the grinding balls will not fall directly due to the presence of the silicone protrusions 12. The first drive motor 10 drives the rotating disk 11 to rotate, and the rotating disk 11 exerts a force on the grinding balls at the upper end, causing the grinding balls to move outward in a disordered manner, thereby reaching the entrance position of the conveying channel 8 and reaching the upper end of the conveyor belt 23 along the conveying channel 8. This design can effectively guide the grinding balls from the auxiliary conveying unit 1 to the main conveying unit 14, improving the efficiency of grinding ball conveying.

[0029] Support frames 13 are welded and fixed at the four corners of the lower end of the transport platform 2. The support frames 13 provide stable support for the entire auxiliary transport unit 1, ensuring that the auxiliary transport unit 1 will not shake during operation and guaranteeing the stability of the grinding ball transport.

[0030] The main transport unit 14 includes a support platform 15, which provides the mounting base for all components of the main transport unit 14. A first drive member 19 and a second drive member 20 are respectively installed on both sides of the upper end of the support platform 15. Both the first drive member 19 and the second drive member 20 consist of an intermediate shaft and drive gears 21, with each set of two drive gears 21 located at the front and rear ends outside the intermediate shaft. A transmission chain 22 is meshed with the exterior of the two front drive gears 21 and the exterior of the two rear drive gears 21. A conveyor belt 23 is fixed to the exterior of the two transmission chains 22, and the conveyor belt 23 is fixed to the chain plates of the transmission chains 22 by clamps. This drive structure transmits the power of the first drive member 19 and the second drive member 20 to the conveyor belt 23 through the transmission chains 22, enabling the conveyor belt 23 to rotate smoothly. The actual transport length of the main transport unit 14 is determined according to the actual situation and differs from the shorter length shown in the figure for clear structural display. Furthermore, to ensure transport effectiveness, it is necessary to add a third drive member, a fourth drive member, etc., in the middle.

[0031] The outer surface of the conveyor belt 23 has multiple V-shaped slots 24 arranged in an array. V-shaped anti-slip belts 25 are fixed within each V-shaped slot 24, and several triangular prisms 26 are fixed within each V-shaped anti-slip belt 25. A grinding ball conveying groove 27 is formed between adjacent triangular prisms 26 inside the V-shaped anti-slip belt 25. The grinding ball conveying groove 27 is in the shape of a frustum of a square pyramid. Grinding balls pass through the rubber plate at the end of the conveyor channel 8 and enter the grinding ball conveying groove 27. Because the grinding ball conveying groove 27 is in the shape of a frustum of a square pyramid, it can accommodate grinding balls of different sizes. Furthermore, after entering, the grinding balls remain stationary relative to the V-shaped anti-slip belts 25 and triangular prisms 26 due to friction, and do not tend to move along the conveyor belt 23. Each grinding ball enters a different grinding ball conveying groove 27, preventing collisions between them. This design ensures the stability and orderliness of the grinding balls during transportation, improving transportation quality and efficiency.

[0032] During the conveying process, not every grinding ball conveying groove 27 at the upper position necessarily contains grinding balls; the grinding ball conveying groove 27 is only for separating the grinding balls.

[0033] A second drive motor 16 is mounted on one side of the front end of the support platform 15. A first bevel gear 17 is mounted on the output shaft of the second drive motor 16. The intermediate shaft of the second drive component 20 passes through the vertical plate on the front support platform 15 and is connected to a second bevel gear 18. The second bevel gear 18 meshes with the first bevel gear 17. The second drive motor 16 drives the first bevel gear 17 to rotate. Through the meshing of the first bevel gear 17 and the second bevel gear 18, the second drive component 20, which is coaxially connected to the second bevel gear 18, rotates, thereby driving the entire conveyor belt 23 to rotate and transport. This drive method has a simple structure, high transmission efficiency, and can provide stable and reliable power for the conveyor belt 23.

[0034] The working process of this casting grinding ball transport device is as follows: The input end of this transport device is connected to the discharge end of the previous stage processing equipment. The grinding balls fall into the loading area 4 of the auxiliary transport unit 1, and then move along the inclined transport table 2 to the convergence area 5. After the initial orderly arrangement in the convergence area 5, they reach the upper end of the rotating disk 11 located in the unloading area 6. Under the action of the silicone bumps 12, the grinding balls do not fall directly, but move outward randomly under the rotation of the rotating disk 11, reaching the entrance of the conveying channel 8, and then moving along the conveying channel 8 to the grinding ball conveying trough 27 at the upper end of the conveyor belt 23. The grinding balls remain stationary in the grinding ball conveying trough 27 and are orderly transported out as the conveyor belt 23 rotates. The entire transport process achieves orderly and stable transport of grinding balls, effectively solving the problems existing in the current grinding ball transport process.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
