[0025] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0026] Example 1

[0027] like Figures 1-4 As shown, an ultrafine mineral admixture proportioning adjustment device includes a mounting bracket 1 and a clamping device 5. A raw material feeding bucket 2 is mounted on the mounting bracket 1. A feeding box 3 is provided at the lower end of the raw material feeding bucket 2. A feeding pull plate 4 is horizontally and elastically inserted into the feeding box 3. The feeding box 3 includes an insertion hole 303, which is horizontally through the feeding box 3. The upper inner surface of the insertion hole 303 connects to the lower end of the raw material feeding bucket 2. The feeding pull plate 4 is inserted into the insertion hole 303. One end of the feeding pull plate 4 elastically abuts against the side of the feeding box 3, and the other end is detachably connected to the clamping device 5. The feeding hole 401 can be aligned with the lower end of the raw material feeding bucket 2 as the feeding pull plate 4 moves. The lower end of the feeding box 3 is closed, and the upper end connects to the lower end of the raw material feeding bucket 2, thus facilitating the removal of raw materials through the feeding pull plate 4. A horizontal guide rod 301 is fixedly installed on the end face of the feeding box 3 away from the clamping device 5. A return spring is fitted on the guide rod 301. A limiting plate 302 is provided on the end of the guide rod 301 away from the feeding box 3. A collision plate 404 is provided on the end of the feeding pull plate 4 away from the clamping device 5. The collision plate 404 is provided with a sliding hole 405 that matches the guide rod 301. The collision plate 404 is slidably mounted on the guide rod 301, with one end face abutting against the return spring and the other end abutting against the limiting plate 302. An elastic pad is provided on the end face of the limiting plate 302 and the collision plate 404 that abuts against each other. The collision plate 404 elastically abuts against the elastic pad by the return spring. The feeding pull plate 4 is elastically inserted into the insertion hole 303 by the return spring and is limited by the collision plate 404 and the limiting plate 302, so that the feeding hole 401 is aligned with the lower port of the raw material feeding bucket 2. The volume of the feeding hole 401 is a fixed 1ml. A certain amount of raw materials can be taken out by repeatedly pulling the feeding plate 4.

[0028] like Figures 2-5As shown, an electric telescopic rod 6 is horizontally mounted on the mounting bracket 1. One end of the clamping device 5 is connected to the electric telescopic rod 6, and the other end is elastically openable and closed with a pair of clamping arms 503. The clamping arms 503 can clamp the material feeding pull plate 4 and pull it in the direction of rebound force. The material feeding pull plate 4 is provided with a material feeding hole 401 for picking up material. The mounting bracket 1 also includes a lever 101. Opening levers 504 are fixedly mounted on the opposite sides of the pair of clamping arms 503. The mounting bracket 1 is provided with levers 101 that are adapted to each opening lever 504. When the pair of clamping arms 503 clamp the material feeding pull plate 4 and pull it out in the direction of rebound force, the opening levers 504 abut against the levers 101, causing the clamping arms 503 to open. It also includes an elastic lever 304. The end of the feeding box 3 near the clamping device 5 is provided with an elastic lever 304 located above the feeding pull plate 4. The upper surface of the feeding pull plate 4 is provided with vibration ripples 402 that are compatible with the elastic lever 304. The electric telescopic rod 6 drives the clamping device 5 to extend and retract horizontally. When it extends to the material discharge plate 4, it is clamped by a pair of clamping arms 503. When it returns, the material discharge plate 4 is pulled out. When the material discharge plate 4 is pulled out, the elastic deflector 304 vibrates through the vibration wave 402, thereby causing the material in the material discharge plate 4 to vibrate and shake out the material in the discharge hole 401. After being pulled out a certain distance, the pair of clamping arms 503 will open and disengage from the material discharge plate 4 through the deflector 101 and the opening deflector 504. The material discharge plate 4 automatically retracts by the return spring and impacts the limiting plate 302. The elastic pad on the limiting plate 302 can cause the material discharge plate 4 to vibrate, so that the material discharge hole at the lower end of the raw material feeding bucket 2 can be fully filled with raw materials for the next round of material pulling out and picking up.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, the clamping device 5 includes a clamping base 501, with rotating bases 502 symmetrically arranged on opposite sides of the clamping base 501. One end of the clamping arm 503 is rotatably mounted on the rotating base 502, and the other end is provided with a clamping claw 505. The end of the unloading pull plate 4 near the clamping device 5 is provided with a clamping head 403 adapted to the clamping claw 505. A clamping spring 507 is connected between the pair of clamping arms 503. The clamping device 5 also includes an abutment wheel 506, which is rotatably mounted at the claw head position of the clamping claw 505. The abutment wheel 506 does not exceed the plane where the clamping claw 505 and the clamping head 403 clamp and abut. When the gripping claws 505 of the pair of gripping arms 503 abut against the gripping head 403, the frictional force is reduced by the abutment wheel 506, thus facilitating the opening of the pair of gripping arms 503. This allows the gripping claws 505 to accurately grip the gripping head 403, and the gripping spring 507 between the pair of gripping arms 503 automatically clamps them tightly. Additionally, a controller with an operation screen is included. The controller allows setting the extension distance and number of extensions of the electric telescopic rod 6. The controller uses a built-in microprocessor (MCU) to implement a complete link of "instruction input - signal processing - execution control - status feedback." Operators set the working parameters of the electric telescopic rod 6 using the proportions, thereby enabling the electric telescopic rod 6 to operate automatically via the microprocessor (MCU). Simultaneously, when the MCU determines that the "number of completed extensions" has reached the "preset number of extensions," it displays "Material handling completed" on the controller display and triggers a "completion prompt sound."

It also includes an elastic lever 304. The end of the feeding box 3 near the clamping device 5 is provided with an elastic lever 304 located above the feeding pull plate 4. The upper surface of the feeding pull plate 4 is provided with vibration ripples 402 that are compatible with the elastic lever 304.
