Description

Technical Field

[0001] This invention relates to the field of intelligent mechanized soil treatment technology, specifically a soil improvement device and method that uses intelligent treatment of mixed slag. Background Technology

[0002] Preparing soil conditioners from mixed slag is an effective method for the resource utilization of industrial waste slag, and it has significant environmental and economic implications. By thoroughly mixing the mixed slag into the soil conditioner, the soil environment can be effectively improved, providing a favorable environment for crop growth in agricultural production.

[0003] Slag is a solid waste generated during metal smelting. Slag has a certain particle size distribution, and after crushing and screening, particles of different sizes can be obtained. These particles have a certain porous structure, which can improve the aeration and permeability of the soil.

[0004] In the process of preparing soil conditioner, slag needs to be treated to make its particle size suitable for soil improvement. Then, it needs to be screened to ensure that the particle size meets the requirements so that it can fully and evenly combine with the soil and avoid some slag from clumping together. If some materials with high moisture content are being processed, the material may adhere to the surface of the blades or screen, which will undoubtedly lead to a decrease in the crushing and screening effect of the material.

[0005] To address this, the adhering material can be treated by converting the impact force on the screen into vibration force. However, the impact force can only treat the screen, and the material adhering to the blades cannot be subjected to force. Furthermore, if the impact force is too large, it may damage the screen, while if the impact force is too small, it will make it difficult for the adhering material to detach from the screen. Summary of the Invention

[0006] The purpose of this invention is to provide a soil improvement device and method that uses intelligent treatment of mixed slag to solve the problems mentioned in the background art.

The intelligent machine body is equipped with a discharge hopper and a screening plate. Multiple air supply pipes are connected to the side wall of the intelligent machine body. An infrared intelligent sensor is installed inside the intelligent machine body. When the mixed slag and / or soil passes through the feeding port at the top of the intelligent machine body, the infrared intelligent sensor is triggered and sends a start signal. Also includes: A first rotating rod is rotatably mounted inside the intelligent machine body, and a crushing component is provided on the first rotating rod; An oscillation mechanism is provided inside the discharge hopper. The oscillation mechanism includes a plurality of vibrating rods distributed equidistantly in a circle, which are used to perform a vibration cleaning action on the screening plate through the vibrating rods. An intensity control component is disposed on the oscillation mechanism. A pressure follower mechanism connected to the intensity control component is disposed on the first rotating rod. The pressure follower mechanism can adjust the distance between the vibrating rods through the intensity control component and the oscillation mechanism when the pressure inside the intelligent machine changes.

[0008] As a further aspect of the present invention: the oscillation mechanism includes a second rotating rod rotatably installed inside the discharge hopper, and a support plate arranged symmetrically on the second rotating rod, wherein a first sliding groove and a second sliding groove arranged symmetrically are formed on the support plate.

[0009] As a further embodiment of the present invention: the oscillation mechanism further includes a first sliding block and a second sliding block that slide along the length directions of the first sliding groove and the second sliding groove respectively, and the first sliding block and the second sliding block are provided with a connecting plate that is slidably connected to the vibration rod, and the connecting plate is provided with an elastic component.

[0010] As a further embodiment of the present invention: the elastic component includes a first fixing ring and a second fixing ring disposed on the vibrating rod, the first fixing ring abutting against the connecting plate, and a second spring sleeved on the vibrating rod, the two ends of the second spring abutting against the second fixing ring and the connecting plate respectively.

[0011] As a further embodiment of the present invention: the strength adjustment component includes a movable sleeve and a follower sleeve that slide along the axial direction of the second rotating rod, and a first connecting rod that is hinged to the first sliding block is mounted on the movable sleeve. It also includes a second connecting rod hinged to the follower sleeve and hinged to the second sliding block, and a third spring is sleeved on the second rotating rod, with the two ends of the third spring abutting against the support plate and the follower sleeve, respectively.

[0012] As a further embodiment of the present invention: the pressure follow-up mechanism includes a slot and a vent hole opened on the first rotating rod, a guide post is provided inside the first rotating rod, a limit ring is provided at the end of the guide post, a sliding ring slides inside the first rotating rod along the axial direction of the guide post and is slidably connected to the slot, and a first spring is sleeved on the guide post, with the two ends of the first spring abutting against the sliding ring and the inner wall of the first rotating rod, respectively. It also includes a driven component disposed on the first rotating rod for driving the movable sleeve to move axially along the second rotating rod.

[0013] As a further embodiment of the present invention: the driven component includes a sliding sleeve that slides along the axial direction of the first rotating rod and is fixedly connected to the sliding ring, the sliding sleeve being rotatably mounted with a rotating ring, and the rotating ring being provided with a support sleeve.

[0014] As a further embodiment of the present invention: the driven component further includes a fixed plate disposed on the bracket, the fixed plate having a through groove, a movable block being slidably installed in the through groove, a support rod being disposed on the movable block and slidably connected to the support sleeve, a rotating sleeve being rotatably installed on the movable sleeve, and a hinge rod being hinged on the movable block for converting the vertical movement of the movable block into the horizontal movement of the rotating sleeve.

[0015] As a further embodiment of the present invention: the crushing assembly includes a fixed disk disposed on the first rotating rod, and the fixed disk is provided with a plurality of crushing rods and air guide plates distributed equidistantly in a circle.

[0016] A soil improvement method, employing a soil improvement device with intelligent treatment of mixed slag as described above, includes the following steps: Step 1: Add the required slag to the intelligent machine body, and the slag will be crushed by the crushing components. Step 2: When sticky slag adheres to the crushing components or screening plates, high-pressure gas can be introduced into the intelligent machine body through the air supply pipe to impact and clean the adhered slag. Step 3: Simultaneously, the oscillation mechanism operates and performs a vibration cleaning action on the screening plate through the vibrating rod; Step 4: If the conductivity of the screening plate decreases, the air pressure inside the intelligent machine increases and acts on the pressure follow-up mechanism, thereby adjusting the distance between the vibrating rods through the intensity adjustment component and the oscillation mechanism to change the force of the vibrating rods on the screening plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can combine airflow impact and knocking vibration to process materials adhering to the crushing component and the screening plate, so as to prevent the problem of reduced crushing and screening efficiency due to excessive adhering materials. Specifically, when the crushing component crushes the material, high-pressure gas is introduced into the intelligent machine body through the air supply pipe. Under the action of gas impact, the material adhering to the crushing component is blown away. When the screening plate is clogged due to material adhesion, the vibration rod is controlled to move through the oscillation mechanism to provide knocking vibration force to the screening plate, so that the material is separated from the screening hole. When the area of ​​clogging of the screening plate is too large, the air pressure in the intelligent machine body increases. The pressure follow-up mechanism is controlled to move, and the knocking force of the vibration rod on the screening plate is adjusted through the intensity adjustment component and the oscillation mechanism to increase the vibration force and ensure that the material is smoothly separated from the screening hole, thereby ensuring the screening rate.

[0018] By adjusting the air pressure inside the intelligent machine, the powder can be better dispersed into individual particles, making it easier for fine particles to pass through the screen. At the same time, under the action of air pressure, the screening plate is subjected to a greater airflow impact force, thereby enhancing the vibration effect of the screening plate, which helps to break up particle agglomerates, improve screening efficiency, and the pressure can form a stable flow field, so that the powder can be evenly distributed on the screening plate during the screening process, reducing the clogging of the screen holes and improving screening efficiency.

[0019] The vibration generated by the impact breaks down the adhesion between the material and the screening plate, preventing sticky materials from clogging the screen holes and reducing screening efficiency. At the same time, the high-pressure airflow applied by the air supply pipe can generate an impact force to a certain extent to peel off the adhered material. Under the air pressure generated by the airflow, the powder can also be sprayed onto the screening plate at a higher speed, making it easier for fine particles to pass through the screening plate under inertia, thus improving the yield of fine powder.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0033] Please see Figures 1-10 In this embodiment of the invention, a soil improvement device using intelligent treatment of mixed slag includes: The support frame 1 and the intelligent body 2 mounted on the support frame 1 are provided with a discharge hopper 3 and a screening plate 8. Multiple air supply pipes 7 are connected to the side wall of the intelligent body 2. An infrared intelligent sensor (not shown in the figure) is installed inside the intelligent body 2. When the mixed slag and / or soil passes through the feeding port at the top of the intelligent body 2, the infrared intelligent sensor is triggered and sends a start signal. Also includes: The first rotating rod 5 is rotatably installed inside the intelligent body 2, and a crushing component is provided on the first rotating rod 5; An oscillation mechanism is provided inside the discharge hopper 3. The oscillation mechanism includes a plurality of vibrating rods 26 distributed equidistantly in a circle, which are used to perform a vibration cleaning action on the screening plate 8 through the vibrating rods 26. An intensity control component is disposed on the oscillation mechanism. A pressure follower mechanism connected to the intensity control component is disposed on the first rotating rod 5. The pressure follower mechanism can adjust the distance between the vibration rod 26 through the intensity control component and the oscillation mechanism when the pressure inside the intelligent body 2 changes.

[0034] Specifically, during slag crushing, the first rotating rod 5 can be controlled to drive the crushing assembly to crush the slag. The crushed material will be conveyed to the discharge hopper 3 through the screening plate 8. Due to the high viscosity of some slag, it may stick to the crushing assembly and the screening plate 8 during the crushing process. Therefore, high-pressure gas can be conveyed into the intelligent machine body 2 through the air supply pipe 7. Under the impact of the high-pressure gas, the raw material sticking to the crushing assembly is purged. At the same time, under the action of the oscillation mechanism, the vibrating rod 26 is controlled to move, so that the vibrating rod 26 provides a knocking vibration force to the screening plate 8, so that the material adhering to the screening plate 8 is dislodged from the screening plate 8 by the vibration force, ensuring that the screening rate of the crushed material increases. If the screen hole blockage area of ​​the screening plate 8 is large, the conveying of slag raw material into the intelligent machine body 2 can be stopped, and the opening of the intelligent machine body 2 can be sealed. The increased air pressure within the intelligent body 2 allows for better dispersion of powder into individual particles, making it easier for fine particles to pass through the screen and thus improving screening efficiency. Simultaneously, the air pressure drives the pressure follow-up mechanism and controls the oscillation mechanism via the intensity control component, increasing the force exerted by the vibrating rod 26 on the screening plate 8. This increases the vibration force on the material adhering to the screening plate 8, ensuring smooth passage. As the screening rate increases, the clogging area of ​​the screen holes in the screening plate 8 decreases, and the pressure within the intelligent body 2 decreases. The pressure follow-up mechanism adaptively adjusts the vibration effect on the screening plate 8. This not only increases the vibration force when the screening plate 8 is clogged, controlling the rapid separation of material from the screening plate 8 and improving the screening effect of the pulverized material, but also prevents the continuous action of the vibrating rod 26 on the screening plate 8 from reducing its service life.

[0035] Please see Figures 1-4 , Figure 6 The crushing assembly includes a fixed disk 9 disposed on the first rotating rod 5, and the fixed disk 9 is provided with a plurality of crushing rods 10 and an air guide plate 11 distributed circumferentially.

[0036] The bracket 1 is equipped with a motor 4, which communicates with the infrared smart sensor via a smart wireless switch. The smart wireless switch receives the start signal and connects the motor 4 to the power supply. The output shaft of the motor 4 is connected to the first rotating rod 5 via a belt 6. The upper end of the smart body 2 is equipped with a feeding hopper, which is openable and closable. When it is necessary to crush slag, the slag can be added into the smart body 2 through the feeding hopper. The motor 4 works and drives the first rotating rod 5 to rotate via the belt 6, thereby driving the crushing rod 10 to move via the fixed plate 9. Under the action of the crushing rod 10, the slag is crushed.

[0037] During the slag crushing process, some slag may adhere to the crushing rod 10 due to its high viscosity. In this case, the air supply pipe 7 can introduce high-pressure airflow into the intelligent machine body 2. Under the impact of the high-pressure airflow, the material adhering to the end of the crushing rod 10 away from the first rotating rod 5 can be impacted and swept away. At the same time, when the end of the crushing rod 10 is misaligned with the air supply pipe 7, the impacting airflow will act on the air guide plate 11. Under the action of the air guide plate 11, the airflow is guided to blow onto the side wall of the crushing rod 10 to treat the material remaining on the side wall of the crushing rod 10. By guiding the airflow direction through the air guide plate 11, it can be ensured that the high-pressure airflow can fully treat the adhering material.

[0038] Please see Figure 4 , Figure 5 , Figure 7 , Figure 9 The oscillation mechanism includes a second rotating rod 21 rotatably mounted inside the discharge hopper 3. A symmetrically arranged support plate 22 is provided on the second rotating rod 21. A first sliding groove 2201 and a second sliding groove 2202 are formed on the support plate 22. The oscillation mechanism also includes a first sliding block 23 and a second sliding block 24 that slide along the length of the first sliding groove 2201 and the second sliding groove 2202, respectively. A connecting plate 25 that is slidably connected to the vibrating rod 26 is provided on the first sliding block 23 and the second sliding block 24. An elastic component is provided on the connecting plate 25. The elastic component includes a first fixing ring 2601 and a second fixing ring 2602 disposed on the vibrating rod 26. The first fixing ring 2601 abuts against the connecting plate 25. A second spring 27 is sleeved on the vibrating rod 26, with both ends of the second spring 27 abutting against the second fixing ring 2602 and the connecting plate 25, respectively.

[0039] In detail, when the screening plate 8 crushes the raw materials, as the screening volume increases, some raw materials may clog the screen holes, resulting in a decrease in the screening efficiency of the screening plate 8. Therefore, it is necessary to provide a knocking vibration force to the screening plate 8 to separate the clogged material from the screen holes. The opening size of the first chute 2201 is larger than that of the second chute 2202, so that the distance between the starting end of the first chute 2201 and the second rotating rod 21 is smaller than the distance between the starting end of the second chute 2202 and the second rotating rod 21. In the initial state, under the action of the strength adjustment component, the first sliding block 23 and the second sliding block 24 are respectively located in the first chute 2201. 01 and the second slide groove 2202 are at the end of the stroke on the side of the second rotating rod 21, so that the distance between the two first sliding blocks 23 is less than the distance between the two second sliding blocks 24. The second spring 27 is in a compressed state, so that the second fixing ring 2602 controls the vibrating rod 26 to have a tendency to move away from the second rotating rod 21. Under the action of the first fixing ring 2601, the vibrating rod 26 is located at the end of the stroke away from the connecting plate 25. At this time, the two vibrating rods 26 associated with the first sliding block 23 are separated from the screening plate 8, and the two vibrating rods 26 associated with the second sliding block 24 are in contact with the screening plate 8.

[0040] When the screening efficiency of the screening plate 8 decreases, the second rotating rod 21 can be driven to rotate by a motor (not shown in the figure), thereby driving the support plate 22 to move. Under the action of the first sliding groove 2201, the second sliding groove 2202, the first sliding block 23, the second sliding block 24 and the connecting plate 25, the vibrating rod 26 moves around the second rotating rod 21. The two vibrating rods 26 will intermittently strike the outer wall of the screening plate 8. Under the action of the vibration force generated by the strike, the material blocked on the screen hole is separated from the screening plate 8, thereby ensuring that the crushed material can be smoothly discharged through the screening plate 8 and transported to the required position through the discharge hopper 3.

[0041] Preferably, the vibration force generated by the impact breaks the adhesion between the material and the screening plate 8, preventing sticky materials from clogging the screen holes and reducing screening efficiency. At the same time, the high-pressure airflow applied by the air supply pipe 7 can generate an impact force to a certain extent to peel off the adhered material. Under the air pressure generated by the airflow, the powder can also be sprayed onto the screening plate 8 at a higher speed, making it easier for fine particles to pass through the screening plate 8 under inertia, thereby improving the yield of fine powder.

[0042] Please see Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 10The strength adjustment component includes a movable sleeve 28 and a follower sleeve 32 that slide along the axial direction of the second rotating rod 21. A first connecting rod 31 that is hinged to the movable sleeve 28 and hinged to the first sliding block 23 is also included. The component also includes a second connecting rod 34 that is hinged to the follower sleeve 32 and hinged to the second sliding block 24. A third spring 33 is sleeved on the second rotating rod 21. The two ends of the third spring 33 abut against the support plate 22 and the follower sleeve 32, respectively.

[0043] It should be noted that, in the initial state, under the action of the pressure follower mechanism, the movable sleeve 28 is located at the end of its stroke away from the support plate 22, so that the distance between the two first sliding blocks 23 is minimized by the first connecting rod 31, and the third spring 33 is in a compressed state, so that the distance between the follower sleeve 32 and the support plate 22 is maximized. Under the action of the second connecting rod 34, the distance between the two second sliding blocks 24 is minimized. At this time, only the two vibrating rods 26 associated with the second sliding blocks 24 are in contact with the screening plate 8, while the other two vibrating rods 26 are in a separated state from the screening plate 8, and the striking force provided by the vibrating rods 26 to the screening plate 8 is at its minimum.

[0044] If the provided impact vibration force is insufficient, the clogging area of ​​the material on the screen holes of the screening plate 8 will continue to increase. At this time, it is necessary to stop adding slag and seal the discharge hopper 3 so that the material and gas in the intelligent machine body 2 can only be discharged through the screening plate 8 to prevent the powder from escaping through the discharge hopper 3 due to the airflow. At the same time, since the conduction area of ​​the screening plate 8 is small, under the action of the air supply pipe 7 continuously delivering high-pressure airflow, the amount of gas entering the intelligent machine body 2 will gradually exceed the rate of discharge through the screening plate 8. Therefore, the air pressure in the intelligent machine body 2 will gradually increase. Under the action of air pressure, it can guide the crushed material to move towards the screening plate 8, so that the material moves towards the screening plate 8 faster to improve the material screening rate. It can also control the movement of the pressure follower mechanism, thereby adjusting the impact force that the vibration rod 26 can provide to the screening plate 8 through the intensity adjustment component. Specifically, under the action of the pressure follower mechanism, the movable sleeve 28 is driven to slide along the axial direction of the second rotating rod 21 and move towards the support plate 22. The movable sleeve 28 also controls the first sliding block 23 to move along the length direction of the first sliding groove 2201 through the first connecting rod 31, and the two first sliding blocks 23 move in a direction away from each other, thereby controlling the vibrating rod 26 to move away from the second rotating rod 21 through the connecting plate 25. When the two vibrating rods 26 associated with the first sliding block 23 move to the position of abutting against the screening plate 8, the movable sleeve 28 just moves to the position of abutting against the follower sleeve 32. All four vibrating rods 26 will provide knocking vibration force to the screening plate 8, making the adhesive... The attached material separates from the screen holes. If the blockage area is still large, under the action of air pressure, the movable sleeve 28 continues to move and pushes the follower sleeve 32 to move, so that the third spring 33 is compressed. Under the action of the movable sleeve 28 and the follower sleeve 32, the first sliding block 23 and the second sliding block 24 are controlled to move synchronously through the first connecting rod 31 and the second connecting rod 34, so as to enhance the striking force of the vibrating rod 26 on the screen plate 8 each time. As the striking continues, the sticky material will gradually separate from the screen holes, so that the air pressure in the intelligent body 2 will gradually decrease, so that the movable sleeve 28 will return to its original position. Under the action of the third spring 33, the follower sleeve 32 will also return to its original position, thereby gradually reducing the striking force of the vibrating rod 26.

[0045] Preferably, the pressure inside the intelligent body 2 can be adaptively adjusted according to the clogging area of ​​the screening plate 8. Under the action of the pressure follow-up mechanism, the number and impact intensity of the vibrating rods 26 acting on the screening plate 8 are controlled by the intensity adjustment component, thereby adaptively adjusting the vibration intensity of the screening plate 8. This ensures that when too much material adheres to the screen holes of the screening plate 8, resulting in a decrease in screening efficiency, the situation can be dealt with in a timely manner by increasing the vibration force.

[0046] Please see Figures 1-4 , Figures 6-8The pressure follower mechanism includes a slot 501 and a vent 502 formed on the first rotating rod 5. A guide post 12 is provided inside the first rotating rod 5, and a limit ring 1201 is provided at the end of the guide post 12. A sliding ring 13 slides along the axial direction of the guide post 12 and is slidably connected to the slot 501 inside the first rotating rod 5. A first spring 15 is sleeved on the guide post 12, and the two ends of the first spring 15 abut against the sliding ring 13 and the inner wall of the first rotating rod 5, respectively. It also includes a driven component disposed on the first rotating rod 5 for driving the movable sleeve 28 to move axially along the second rotating rod 21. The driven component includes a guide post 1201 and a vent 502 formed on the first rotating rod 5. The first rotating rod 5 slides axially and is fixedly connected to the sliding ring 13. A rotating ring 16 is rotatably mounted on the sliding sleeve 14. A support sleeve 19 is provided on the rotating ring 16. The driven component also includes a fixed plate 17 provided on the bracket 1. A through groove 1701 is opened on the fixed plate 17. A movable block 18 is slidably mounted in the through groove 1701. A support rod 20 is provided on the movable block 18 and slidably connected to the support sleeve 19. A rotating sleeve 29 is rotatably mounted on the movable sleeve 28. A hinge rod 30 is hinged on the movable block 18 to convert the vertical movement of the movable block 18 into the horizontal movement of the rotating sleeve 29.

[0047] Furthermore, in the initial state, the first spring 15 is in a compressed state, causing the sliding ring 13 to be in contact with the limiting ring 1201, so that the sliding sleeve 14 is located at the end of its stroke towards the intelligent body 2. The sliding sleeve 14, the support sleeve 19, the support rod 20, and the movable block 18 form a vertical triangular system. Since one of the right-angled sides represented by the sliding sleeve 14 is the shortest, the movable block 18 will be controlled by the support sleeve 19 and the support rod 20 to be located at the end of its stroke towards the sliding sleeve 14. Under the action of the hinge rod 30, the movable sleeve 28 is located at the end of its stroke away from the support plate 22. At this time, the size of the support sleeve 19 and the support rod 20 when they fit together is the largest. Since the discharge hopper 3 and the screening plate 8 are both in a conductive state, the air pressure inside the intelligent body 2 will not be too high. Therefore, the air pressure force on the sliding ring 13 is less than the supporting force provided by the first spring 15. If too much material adheres to the screen holes of the screening plate 8 during the screening process, it will lead to an increase in the area of ​​the screening plate 8 that is blocked, and a decrease in screening efficiency. At this time, the discharge hopper 3 can be blocked. Under the action of the air supply pipe 7, the air pressure in the intelligent body 2 will gradually increase and act on the sliding ring 13 through the air vent 502. When the air pressure exceeds the supporting force of the first spring 15, the sliding ring 13 will slide along the guide column 12 and drive the sliding sleeve 14 to move. This will control the movement of the support sleeve 19 through the rotating ring 16. At this time, the length of the right angle side of the sliding sleeve 14 in the vertical triangular system increases. Under the action of the support sleeve 19 and the support rod 20, the movable block 18 slides along the through groove 1701 and moves away from the first rotating rod 5. The movable block 18 will also control the movement of the rotating sleeve 29 through the hinge rod 30 to drive the movable sleeve 28 to move towards the support plate 22. This will adjust the impact vibration force of the vibrating rod 26 on the screening plate 8 through the strength adjustment component.

[0048] Preferably, by changing the air pressure inside the intelligent body 2, the force exerted by the vibrating rod 26 on the screening plate 8 can be adaptively controlled, thereby achieving the effect of automatically cleaning the adhering materials. Under the action of air pressure, the screening plate 8 can be subjected to a greater airflow impact force, thereby enhancing the vibration effect of the screening plate 8, which helps to break up particle agglomerates, improve screening efficiency, and the pressure can form a stable flow field, so that the powder can be evenly distributed on the screening plate 8 during the screening process, reducing the clogging of the screen holes and improving screening efficiency.

[0049] A soil improvement method, employing a soil improvement device with intelligent treatment of mixed slag as described above, includes the following steps: Step 1: Add the required slag to the intelligent machine 2, and the slag will be crushed by the crushing components. Step 2: When sticky slag adheres to the crushing component or the screening plate 8, high-pressure gas can be introduced into the intelligent machine body 2 through the air supply pipe 7 to impact and clean the adhered slag. Step 3: Simultaneously, the oscillation mechanism operates and performs a vibration cleaning action on the screening plate 8 through the vibrating rod 26; Step 4: If the conductivity of the screening plate 8 decreases, the air pressure inside the intelligent body 2 increases and acts on the pressure follow-up mechanism, thereby adjusting the distance between the vibrating rods 26 through the intensity adjustment component and the oscillation mechanism to change the force of the vibrating rods 26 on the screening plate 8.
