Description

Technical Field

[0001] This utility model relates to the field of ball milling equipment technology, and in particular to a chain-plate lifting type automatic ball feeder. Background Technology

[0002] Ball mills are the most widely used grinding and mixing machinery today, widely applied in industries such as mineral processing, building materials, power, cement, and chemicals. The grinding process plays a crucial role in the entire production process, representing a significant portion of investment and energy consumption, and greatly impacting product quality. Ball mills achieve their grinding function by filling the mill with grinding balls (mostly steel balls), and the grinding effect is determined by the quality of these steel balls. Once the ball mill begins grinding, the steel balls inside will wear down, reducing the total ball quantity. To maintain optimal ball quantity and ratio, it is necessary to continuously replenish the steel balls.

[0003] An automatic ball feeder is a device used in abrasive grinding in mines to continuously fill the ball mill with steel balls to compensate for the wear and tear caused by the ore. A reasonable ball feeder mechanism is one of the important ways to improve processing capacity. In the early stages of the abrasive grinding industry, traditional manual or semi-manual methods were often used to add steel balls to meet the need for continuous replenishment of steel balls of various specifications during production. This method is not only labor-intensive, but also difficult to maintain a high filling rate due to the limitations of objective conditions on site, and it is easy to cause unreasonable steel ball ratios.

[0004] To address these issues, this application presents a chain-plate lifting type automatic ball feeder. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this utility model provides a chain-plate lifting type automatic ball-adding machine.

[0006] A chain-plate lifting type automatic ball-adding machine, comprising a base frame, characterized in that:

[0007] The right side of the base frame is the ball chamber, which is used to hold the steel balls to be added, and the left side is the installation position of the transmission component. The steel balls slide out from the ball chamber to the left side and are conveyed out of the ball adding machine by the transmission component on the left side.

[0008] Furthermore, in order to better realize this utility model, a power roller part is installed on the left side of the base frame. The power roller part includes a seated bearing, a drive roller is installed on the seated bearing, a drive wheel is connected to the drive roller, the drive wheel is connected to the lifting chain, and the drive roller is connected to the motor reducer through a coupling.

[0009] Furthermore, in order to better realize this utility model, the motor reducer is mounted on a reducer base, and the reducer base is fixedly connected to the base frame.

[0010] Furthermore, in order to better realize this utility model, a tensioning roller part is installed below the power roller part. The tensioning roller part includes a slider bearing seat, on which the tensioning roller is installed. A driven wheel is connected to the tensioning roller, and the driven wheel is connected to the lifting chain.

[0011] Furthermore, in order to better realize this utility model, the slider bearing seat adjusts its longitudinal height by means of a vertical push rod, thereby adjusting the distance between the master and slave wheels and tightening the lifting chain.

[0012] Furthermore, in order to better realize this utility model, a ball chute is installed at the tail end of the base frame to carry the steel balls out of the equipment, and a counting sensor is set at the end of the ball chute to record the number of balls discharged.

[0013] Furthermore, in order to better realize this utility model, the lifting chain is provided with a curved plate chain joint, and a claw is fixed on the curved plate chain joint. The claw rotates and lifts with the chain around the sprocket.

[0014] Furthermore, in order to better realize this utility model, a flap is installed in the ball chamber, and a striking block is installed on the flap. The position of the striking block can be adjusted by the top screw fixed on the flap. The flap is hinged to the bottom plate of the ball chamber through a hinge shaft. When the claw is lifted upward, it impacts and contacts the striking block, causing the flap to vibrate and preventing the steel ball from getting stuck.

[0015] Furthermore, in order to better realize this utility model, a vibrator is installed on the bottom plate of the ball chamber to prevent the ball from falling.

[0016] The beneficial effects of this utility model are:

[0017] High-efficiency continuous ball feeding: Through the coordinated drive of the power roller and the lifting chain, and the rotational lifting action of the claw, continuous and stable conveying of steel balls is achieved, which significantly improves the ball feeding efficiency.

[0018] Anti-jamming design: The vibration mechanism of the flap and the impact block triggers the flap to swing during the lifting process of the claw, which effectively avoids the problem of steel balls getting stuck at the ball chamber outlet and ensures smooth ball delivery.

[0019] Precise counting control: A counting sensor at the end of the ball chute records the number of balls ejected in real time. Combined with the anti-ball-splashing function of the vibrator, it ensures the accuracy of the steel ball ratio and the stability of the process.

[0020] Compact and reliable structure: The tension roller section adjusts the chain tension through a vertical push rod, improving transmission stability; the overall modular design reduces maintenance costs and extends the service life of the equipment.

[0021] High degree of automation: From steel ball lifting and vibration anti-clogging to counting output, the entire process is automated, greatly reducing manual intervention and labor intensity, and is suitable for industrial environments with high dust and high load. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] Figure 1 This is a specific embodiment of the present invention, which is a chain-plate lifting type automatic ball-adding machine, and its specific implementation method is as follows:

[0032] After the steel ball is placed in the ball compartment of the base frame 1, the vertical gap between the ball compartment upright plate 102 and the ball compartment bottom plate 101 ensures that when the steel ball slides out of the ball compartment outlet, when it is laid on the lifting plate 10, the anti-pressure plate 103 can effectively solve the problem of the weight of the steel ball pressing on the outlet and affecting the ball output efficiency.

[0033] The motor reducer 8 drives the power roller part 5 to rotate around the shaft, and then the drive wheel 503 drives the lifting chain 7 and the driven wheel 603 to rotate. The vertical push rod 15 can adjust the longitudinal height of the slider bearing seat 601, thereby adjusting the distance between the drive and driven wheels and tightening the lifting chain 7.

[0034] The claw 3 is fixed to the curved chain joint 701 of the lifting chain 7. The lifting chain 7 drives the claw 3 to rotate around the axis. When the claw 3 rotates to the bottom of the flap 10, the tip of the claw 3 strikes the impact block 12, causing the flap 10 to swing around the hinge axis 11. The set screw 13 fixed on the flap 10 can adjust the contact area between the impact block 12 and the tip of the claw 3, thereby adjusting the swing amplitude of the flap 10 and preventing the steel ball from getting stuck in the ball chamber.

[0035] After the claw 3 lifts the steel ball to the ball chute 4, the steel ball separates from the claw 3 and slides out of the ball adding machine along the slide of the ball chute 4. At this point, one ball adding action is completed, and the claw 3 continues to rotate around the axis to enter the next working cycle.

[0036] The counting sensor 14 installed at the tail end of the ball chute 4 can record the number of balls dispensed, ensuring the ball addition ratio.

[0037] The vibrator 2 at the bottom of the ball compartment bottom plate 101 can be activated after the time interval of no ball release is detected, as set by the counting sensor 14, to prevent the steel ball in the ball compartment from sloshing.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
