Description

Technical Field

[0001] This application relates to the field of mineral processing technology, specifically to an automatic quantitative feeding and loading device for mineral materials. Background Technology

[0002] Mineral materials refer to mineral or rock materials in mineral resources that can be used for industrial production. Mineral resources refer to natural mineral or rock resources formed by geological processes that have utilization value, including metallic minerals, non-metallic minerals, and combustible organic minerals.

[0003] Currently, in the process of loading and unloading mineral materials, the materials are generally stored in a hopper and released by opening a valve. The amount of material released is usually judged manually, but the error of manual judgment is large, resulting in a large deviation between the amount of material released and the actual demand, making it difficult to achieve automatic quantitative feeding. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose an automatic quantitative feeding and loading device for mineral materials to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides an automatic quantitative feeding and loading device for mineral materials, including a feeding box, a discharge port at one end of the feeding box, a hopper movably mounted on the top of the feeding box via a swing mechanism, a pusher platform slidably connected inside the feeding box via a drive mechanism, a limit shaft provided on the inner side of the feeding box, a guide plate fixedly connected to the end of the feeding box near the discharge port, and a protective cover fixedly connected to the outer surface of the guide plate.

[0006] Preferably, the swing mechanism includes a telescopic rod slidably connected to the inner surface of the discharge box, and a spring is movably sleeved on the outer surface of the telescopic rod. When the hopper is blocked, the swing mechanism can clear the blockage by shaking.

[0007] Preferably, the driving mechanism includes a crossbar fixedly connected to the inside of the feeding box, an electric push rod rotatably connected to the outer surface of the crossbar, a recessed seat fixedly connected to the output end of the electric push rod, and a seat shaft rotatably connected to the inner surface of the recessed seat. The driving mechanism can drive the feeding table to feed materials during its movement.

[0008] Preferably, a fixed shaft is fixedly connected inside the feeding box, and a swing arm is rotatably connected to the outer surface of the fixed shaft, with the top of the swing arm rotatably connected to the outer surface of the seat shaft.

[0009] Preferably, an arm shaft is fixedly inserted through the inner side of the swing arm, and a side connecting bar is rotatably connected to the outer surface of the arm shaft.

[0010] Preferably, the bottom of the side connecting bar is rotatably connected to a sliding shaft, and the outer surface of the pusher table is provided with a strip-shaped hole, and the inner side of the strip-shaped hole is slidably connected to the outer surface of the sliding shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This automatic quantitative feeding and loading device for mineral materials achieves precise quantitative control of material feeding through the precise mechanical linkage of electric actuators, recessed seats, swing arms, and a pusher platform. During each feeding, the pusher platform moves with a fixed stroke and cycle under the drive of the electric actuator, ensuring that the amount of material fed out each time is basically consistent and reducing errors caused by manual judgment.

[0013] 2. When blockage occurs in the hopper of this automatic quantitative feeding and loading device for mineral materials, the hopper is moved back and forth, causing the telescopic rod to extend and retract within the feeding box under the elastic action of the spring. This causes the hopper to shake, and the shaking of the hopper generates physical vibrations. These vibrations can break the tight contact between the material particles, loosen them, and rearrange them, thereby resolving the blockage. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figure 1-3An automatic quantitative feeding and loading device for mineral materials includes a feeding box 1, a discharge port 2 at one end of the feeding box 1, a hopper 3 movably mounted on the top of the feeding box 1 via a swing mechanism, a pusher 6 slidably connected inside the feeding box 1 via a drive mechanism, a limit shaft 17 provided on the inner side of the feeding box 1, a guide plate 18 fixedly connected to the end of the feeding box 1 near the discharge port 2, and a protective cover 19 fixedly connected to the outer surface of the guide plate 18.

[0020] With the above technical solution, when the device is in use, the mineral material is put into the hopper 3, and the pusher platform 6 is located below the hopper 3. It blocks the discharge port of the hopper 3, preventing the material from falling. When discharging, the pusher platform 6 is driven by the drive mechanism to change its position. When the pusher platform 6 no longer blocks the discharge port of the hopper 3, the material in the hopper 3 can be discharged smoothly and pushed out from the discharge port 2 by the pusher platform 6.

[0021] Specifically, the swing mechanism includes a telescopic rod 4 that is slidably connected to the inner surface of the feeding box 1, and a spring 5 is movably sleeved on the outer surface of the telescopic rod 4.

[0022] Through the above technical solution, during the extension and retraction of the telescopic rod 4 within the discharge box 1, it will compress the spring 5, causing it to generate a reverse buffering force.

[0023] Specifically, the drive mechanism includes a crossbar 7 fixedly connected to the inside of the feeding box 1, an electric push rod 8 rotatably connected to the outer surface of the crossbar 7, a recess 9 fixedly connected to the output end of the electric push rod 8, and a seat shaft 10 rotatably connected to the inner surface of the recess 9.

[0024] Through the above technical solution, the crossbar 7 is designed to adapt to the angle deflection of the electric push rod 8 itself. During the process of pushing and pulling the concave seat 9, the concave seat 9 will rotate along the seat shaft 10.

[0025] Specifically, a fixed shaft 11 is fixedly connected inside the material box 1, and a swing arm 12 is rotatably connected to the outer surface of the fixed shaft 11. The top of the swing arm 12 is rotatably connected to the outer surface of the seat shaft 10.

[0026] Through the above technical solution, as the swing arm 12 rotates along the fixed axis 11, it will drive the side connecting bar 14 through the arm shaft 13, causing it to deflect.

[0027] Specifically, an arm shaft 13 is fixedly inserted through the inner side of the swing arm 12, and a side connecting bar 14 is rotatably connected to the outer surface of the arm shaft 13.

[0028] Through the above technical solution, the top of the side connecting bar 14 will move with the movement of the arm shaft 13 (the arm shaft 13 performs partial circumferential motion when the swing arm 12 rotates), while the bottom of the side connecting bar 14 is relatively limited by the strip hole 16.

[0029] Specifically, the bottom of the side connecting bar 14 is rotatably connected to a sliding shaft 15, and the outer surface of the pusher table 6 is provided with a strip-shaped hole 16, and the inner side of the strip-shaped hole 16 is slidably connected to the outer surface of the sliding shaft 15.

[0030] Through the above technical solution, as the side connecting bar 14 moves upward and toward the discharge port 2, it will slide along the strip hole 16 and push and pull the pusher table 6 through the strip hole 16.

[0031] Working Principle: During operation, the mineral material is fed into the hopper 3. The pusher platform 6 is positioned below the hopper 3, blocking the discharge port and preventing material from falling. During discharge, the electric actuator 8 is activated to pull the recessed seat 9. As the recessed seat 9 rotates along the seat shaft 10, it drives the swing arm 12, causing it to rotate along the fixed axis 11. During this rotation, the arm shaft 13 on the swing arm 12 makes a circular motion, causing the swing arm 12 to move downwards and away from the hopper 3. Simultaneously, the swing arm 12 slides downwards along the slotted hole 16, pulling the pusher platform 6 inwards. When the pusher platform 6 no longer blocks the bottom outlet of the hopper 3, the material can fall from the hopper 3 into the discharge box 1. Then, the electric actuator 8 can drive the pusher platform 6 outwards. The material falling into the discharge box 1 is discharged from the discharge port 2, and the bottom outlet of the hopper 3 will gradually be blocked again. When the pusher 6 abuts against the limit shaft 17, the material is discharged. This periodic cycle drives the pusher 6 to push the material, which can quantitatively discharge the material. Compared with completely manual judgment, it greatly improves the accuracy. As the material is guided along the guide plate 18 to the loading platform, the protective cover 19 can effectively reduce the scattering of the material during the guiding process and also play a certain role in dust reduction. When the hopper 3 is blocked, the hopper 3 can be moved back and forth, so that the telescopic rod 4 can extend and retract back and forth in the discharge box 1 under the elastic action of the spring 5, thereby causing the hopper 3 to shake. By shaking the hopper 3, physical vibration can be generated. These vibrations can break the tight contact between the material particles, loosen them and rearrange them, thereby solving the blockage.
