In addition, the material is processed more thoroughly during pre-processing, which avoids that when processing the material, only one method can be used at a time, resulting in incomplete material processing, and rework is required later to increase the time and cost of processing. When an abnormality occurs at the processing end, it can be detected in time, and the power supply of the power end can be cut off at the first time, and the power end is stopped to protect it;

During the detection process, different materials can be automatically detected, avoiding the situation where only one material can be detected at a time during the detection process and manual intervention is required, resulting in low detection efficiency. During the detection process, the detection end can rotate and the detection liquid and material inside the detection end can be vibrated during the rotation. The comprehensive treatment can not only increase the detection efficiency of the detection end, but also improve the sufficiency of the contact between the material and the detection liquid, avoiding the situation where the detection liquid is not in sufficient contact with the material during the detection process, resulting in errors in the final detection and judgment results.

[0042] The specific implementation method is as follows: during the process of testing the material, the material to be processed is placed at the bottom of the inner cavity of the working frame 2, the electric push rod 301 and the single-phase motor 306 are started, and the extrusion block 302 and the friction block 303 are driven downward by the electric push rod 301 to crush the placed material, and the belt strip 313 is driven to rotate by the single-phase motor 306, and the extrusion block 302 and the friction block 303 are driven to rotate, so that the material is subjected to rotational friction during the crushing process, and when the extrusion block 302 rotates, the installation ring is driven The strip 410 rotates inside the mounting ring rail 406, increasing the stability of the extrusion block 302 and the friction block 303 during the rotation process. When the belt strip 313 rotates, a torque is generated. Since no friction is generated when the friction block 303 and the extrusion block 302 rotate, the tightness of the belt strip 313 is not enough. When the friction block 303 is abnormal during the rotation and use, resulting in excessive friction, the torque generated by the belt strip 313 becomes larger, making the diameter of the belt strip 313 smaller. The pushing spring 311 in the contracted state drives the squeezing rods 312 on both sides to move to the opposite side, thereby reducing the distance between the V-shaped squeezing strip 308 and the V-shaped squeezing sleeve 310, and making the squeezing rod 312 contact with the reverse control switch, and closing the circuit of the single-phase motor 306 through the control panel to stop the single-phase motor 306 from working, so as to avoid the belt strip 313 from breaking due to the continued operation when an abnormality occurs. In addition, in the process of processing the material, the crushing pressure and the friction during grinding are carried out simultaneously, which can not only improve the efficiency of material processing, but also reduce the steps in the processing process, and do not need to complete only one operation at a time, and the material can be processed more thoroughly during pre-processing, so as to avoid that when processing the material, only one method can be used at a time, resulting in incomplete material processing, and rework is required in the later stage to increase the time and cost of processing. When an abnormality occurs at the processing end, it can be detected in time, and the power supply of the power end can be cut off at the first time, and the work is stopped to protect the power end.
[0043] The sealing processing mechanism 4 also includes an extrusion airbag 402, a fixed ring plate 403, an annular slide 404, an annular sleeve 405, an installation ring rail 406, an annular air hole 407, an annular cleaning hole 409 and an installation ring strip 410. A fixed ring plate 403 is installed on the upper end of the inner cavity of the working frame 2, and an annular slide 404 is installed on the lower end of the fixed ring plate 403.

Round beads are equidistantly installed around the mounting ring strip 410. The rubber sealing ring 408 is made of synthetic rubber material;
[0044] The specific implementation is as follows: when the extrusion block 302 moves, it will drive the rubber sealing ring 408 to move, so that the rubber sealing ring 408 rubs around the inner cavity of the working frame 2, and the inner cavity of the working frame 2 is processed around to prevent a large amount of dirt from being attached around the inner cavity of the working frame 2. When the extrusion block 302 moves downward, the extrusion airbag 402 is stretched by the movement of the mounting ring plate 401. When the mounting ring plate 401 rotates, the extrusion airbag 402 is driven to rotate. When the extrusion airbag 402 rotates, the annular sliding sleeve 405 is driven to slide outside the annular sliding strip 404. It will not affect the normal rotation of the extrusion block 302, and can also improve the stability of the extrusion block 302 during rotation. When the extrusion block 302 moves upward to reset, the stretched extrusion airbag 402 is squeezed, and the air inside the extrusion airbag 402 is transported to the rubber sealing ring 408 through the annular air hole 407, and the dirt accumulated between the rubber sealing ring 408 is cleaned away through the annular cleaning hole 409, thereby increasing the stability of the rubber sealing ring 408 during use and avoiding excessive dirt accumulation between the rubber sealing ring 408, which affects the normal use in the later stage.

[0046] A rotating rod 502 is installed in the middle of the circular plate 503, and a mounting circular frame 506 is installed at the bottom end of the inner cavity of the working bottom frame 1, which is located in the middle of the annular sliding frame 511. The bottom end of the rotating rod 502 is located at the upper end of the inner cavity of the mounting circular frame 506, and a mounting round block 508 is installed. A plurality of round balls are installed around the outer periphery of the mounting round block 508, and a plurality of rolling balls are installed around the bottom end of the rotating rod 502. A return spring ring 507 is installed at the bottom end of the rotating rod 502, and one end of the return spring ring 507 is connected to one side of the inner cavity of the mounting circular frame 506. The return spring ring 507 is in a compressed state. A limited circular plate 505 is installed at the top of the rotating rod 502, and a detection liquid is added to the bottom end of the detection cup 504.
[0047] A stabilizing sleeve is installed at the middle and upper end of the rotating rod 502, and the upper end of one side of the stabilizing sleeve is connected to the top of the inner cavity of the working bottom frame 1. The bottom of the collecting bucket 501 is provided with mounting circular openings, and a mounting cylinder is installed inside the mounting circular openings. Vibrating rods 11 are arranged on both sides of the detection cup 504. Two vibrating plates 12 are staggered at the bottom and middle and lower ends of the inner cavity of the detection cup 504. One side of the right vibrating rod 11 passes through the inside of the mounting cylinder and is connected to the top of the vibrating plate 12 at the middle and lower ends. One side of the left vibrating rod 11 passes through the mounting cylinder on the left and is connected to the top of the vibrating plate 12 at the bottom. The vibrating rod 11 is U-shaped, and a number of spring rods are installed around the inside of the mounting cylinder, and the end of the spring rod away from the mounting cylinder is connected to the outside of the vibrating rod 11.
[0048] The specific implementation is as follows: when the limiting circular plate 505 loses its restraining force, the return spring coil 507 in a compressed state drives the rotating rod 502 to rotate, and drives the mounting round block 508 to rotate inside the mounting round frame 506, thereby improving the stability of the rotating rod 502 and the limiting circular plate 505 during rotation. When the limiting circular plate 505 rotates, the round ball at the bottom end of the limiting block 702 rotates on the upper end of the limiting circular plate 505, thereby reducing the friction during the rotation process. When the limiting block 702 rotates to the position of the limiting recess 701, the limiting block 702 will be embedded in the limiting recess 701, thereby ensuring the stability of the limiting circular plate 505 and the rotating rod 502. The movable rod 502 is fixed in a limited position to increase the stability during the receiving process. When the circular plate 503 rotates, it drives the surrounding mounting rods 509 to rotate, and drives the placement bottom frame 510 and the detection cup 504 to rotate. When the processed material falls into the detection cup 504, the processed material is in contact with the detection liquid in the detection cup 504. When the placement bottom frame 510 moves, it drives the rotating block 512 to slide inside the annular sliding frame 511, and drives the rotating block 512 to rotate through friction. When the rotating block 512 rotates, it drives the placement bottom frame 510 and the detection cup 504 to rotate, and the detection cup 504 rotates When the collecting bucket 501 rotates, the annular mounting strip 514 will be driven to slide inside the annular mounting rail 513, increasing the stability and flexibility of the bottom frame 510 and the detection cup 504 when they are rotated. When the collecting bucket 501 rotates, the vibration rods 11 on both sides will be driven to rotate. When the vibration rods 11 rotate to the position of the mounting rods 509, the bottom ends of the vibration rods 11 will contact and collide with the outside of the mounting rods 509, causing the vibration rods 11 to generate vibration force, and the elasticity generated by the elastic rods will make the vibration frequency of the vibration rods 11 longer. When the vibration rods 11 vibrate, the vibration sheet 12 will be driven to vibrate at the bottom end of the inner cavity of the detection cup 504, causing the detection liquid to generate vibration with the material. Vibration, during the detection process, different materials can be automatically detected, avoiding the situation where only one material can be detected at a time and manual intervention is required, which leads to low detection efficiency. In the detection process, the detection end can rotate and vibrate the detection liquid and material inside the detection end. The comprehensive treatment can not only increase the efficiency of the detection process of the detection end, but also improve the sufficient contact between the material and the detection liquid, avoiding the situation where the detection liquid is not in sufficient contact with the material during the detection process, resulting in errors in the final detection judgment results.

Sliding holes are installed around the top of the fixed frame 304, just above the movable slide bars 603.

[0050] The specific implementation is as follows: when the fixed frame 304 moves downward, the movable slide rod 603 slides in the slide hole, so that the distance between the upper end of the inner cavity of the fixed frame 304 and the upper end of the movable plate 605 becomes smaller, and the cleaning air bag 601 is pressurized, and the air inside the cleaning air bag 601 is squeezed into the inside of the annular air bag through the timing solenoid valve and the air pipe. When the squeezing block 302 moves downward and contacts the touch timing switch 305, the timing solenoid valve is closed so that the air inside the annular air bag will not leak. When the set time is reached, the timing solenoid valve is opened again. When the squeezing block 302 and the friction block 303 move upward to reset, they contact the induction switch 307 and start the timing valve head, and then the annular The cleaning tube 602 transports the air stored in the annular airbag to the inside of the working frame 2, so that the ejected airflow is at the bottom of the extrusion block 302 and the outside of the friction block 303, and the outside of the extrusion block 302 and the friction block 303 after work are processed, and the dirt attached to the outside of the processing end is removed, so as to increase the stability when it is used again in the later period, and improve the accuracy of the later detection results, so as to avoid the residues attached to the processing end being mixed with the processed sample during the use of the processing end, and in the later detection process, because the purity of the raw materials for detection is not enough, the final detection result will have errors, resulting in reduced accuracy of the final detection and misjudgment.
[0051] The limiting mechanism 7 also includes a limiting notch 701, a limiting block 702, a reset spring 703, a mounting notch 704, a mounting lever 705, a movable lever 707 and a pulling rope 708. A plurality of limiting notches 701 are equidistantly provided around the top of the limiting circular plate 505. The limiting notches 701 correspond to the number and position of the mounting rods 509 respectively. A movable lever 707 is installed on one side of the inner cavity of the movable notch 706 through a rebound hinge. The movable lever 707 is in an inclined state. A pulling rope 708 is movably installed on the right side of the movable lever 707. A mounting notch 704 is provided on the right side of the inner cavity top of the working bottom frame 1, which is located just above the rotating rod 502. The mounting notch A mounting lever 705 is provided at the bottom end of the inner cavity of the opening 704, and a hinge is installed at the top end of the mounting lever 705 and the upper end of the inner cavity of the mounting recess 704. The end of the pull rope 708 away from the movable lever 707 passes through the working frame 2 and the inside of the working bottom frame 1 and is connected to the left side of the top end of the mounting lever 705. A limiting block 702 is installed on the right side of the bottom end of the mounting lever 705. A return spring 703 is installed on the right side of the top end of the mounting lever 705.

A plurality of balls are installed at the bottom end and the bottom of the limiting block 702, and the limiting block 702 is butted with the inner cavity of the limiting recess 701 on the right side.
[0052] The specific implementation method is as follows: when the extrusion block 302 moves downward, one side of the extrusion block 302 contacts the left side of the movable lever 707, and the right side of the movable lever 707 moves upward, and the elasticity of the pulling rope 708 is used to stretch the rope in a small range. When the extrusion block 302 moves upward, the right side of the extrusion block 302 contacts the left side of the movable lever 707, and the right side of the movable lever 707 is driven downward with the rebound hinge as the axis, thereby compressing the rebound hinge, and later the movable lever is driven by the compressed rebound hinge. When 707 and the pulling rope 708 are reset, the mounting lever 705 and the limit block 702 are reset, and the pulling rope 708 is in a relaxed state. When the pulling rope 708 is in a relaxed state, the mounting lever 705 loses its restraining force, and the restoring spring 703 in the stretched state drives the right side of the mounting lever 705 to move upward with the hinge as the axis, which drives the limit block 702 to move upward, so that the limit block 702 is separated from the inside of the limit recess 701 at the corresponding position, and the limit circular plate 505 loses its restraining force.
[0053] The unloading mechanism 8 also includes a U-shaped stop bar 802 and a small electric telescopic rod 804. The U-shaped stop bar 802 is installed on the top of the support plate 803. The U-shaped stop bar 802 is made of rubber material. A small electric telescopic rod 804 is installed on the left side of the inner cavity of the working bottom frame 1 through a hinge. The telescopic end of the small electric telescopic rod 804 is connected to the bottom end of the support plate 803 through a hinge.

A feeding frame head 10 is installed at the middle and lower end of the left side of the working frame 2, and a movable baffle 9 is installed on the front side of the working bottom frame 1.
[0054] The specific implementation method is: when unloading, the touch timing switch 305 is triggered to start the small electric telescopic rod 804 through the control panel, so that the telescopic end of the small electric telescopic rod 804 retracts back, and the right end of the support plate 803 is driven to move downward with the hinge as the axis, so that the support plate 803 is tilted, and the bottom end of the unloading hopper 801 is in a state without any obstruction, so that the processed material is discharged, and the material is guided through the tilted support plate 803, thereby increasing the efficiency of unloading after processing.
[0055] Working principle: In the process of testing the material, the present invention places the material to be processed at the bottom of the inner cavity of the working frame 2, starts the electric push rod 301 and the single-phase motor 306, and drives the extrusion block 302 and the friction block 303 to move downward through the electric push rod 301 to crush the placed material, and drives the belt strip 313 to rotate through the single-phase motor 306, and drives the extrusion block 302 and the friction block 303 to rotate, so that the material is subjected to rotational friction during the crushing process, and when the extrusion block 302 rotates, it drives the mounting ring strip 410 to rotate inside the mounting ring rail 406, thereby increasing the stability of the extrusion block 302 and the friction block 303 during the rotation process, and when the belt strip 313 rotates, a tightening rotational force is generated, and due to When the friction block 303 and the extrusion block 302 rotate, no friction is generated, and the tightness of the belt strip 313 is not enough. When the friction block 303 is abnormal during rotation and causes the friction force to be too large, the torque generated by the belt strip 313 will increase, causing the diameter of the belt strip 313 to decrease, and the extrusion rods 312 on both sides are driven to move to the opposite side by the pushing spring 311 in a compressed state, so that the distance between the V-shaped extrusion strip 308 and the V-shaped extrusion sleeve 310 is reduced, and the extrusion rod 312 is brought into contact with the reverse control switch, and the circuit of the single-phase motor 306 is turned off through the control panel, so that the single-phase motor 306 stops working, thereby avoiding the situation where the belt strip 313 continues to work when an abnormality occurs, causing the belt strip 313 to break.
[0056] When the extrusion block 302 moves downward, one side of the extrusion block 302 contacts the left side of the movable lever 707, and the right side of the movable lever 707 moves upward, and the rope 708 is stretched in a small range by its own elasticity. When the extrusion block 302 moves upward, the right side of the extrusion block 302 contacts the left side of the movable lever 707, and the right side of the movable lever 707 is driven downward with the rebound hinge as the axis, thereby compressing the rebound hinge. When the rope 708 is pulled to reset, the installation lever 705 and the limit block 702 are reset, so that the pull rope 708 is in a relaxed state. When the pull rope 708 is in a relaxed state, the installation lever 705 loses its restraining force, and the right side of the installation lever 705 is driven upward by the reset spring 703 in the stretched state with the hinge as the axis, which drives the limit block 702 to move upward, so that the limit block 702 is separated from the inside of the limit notch 701 at the corresponding position, and the limit circular plate 505 loses its restraining force;
[0057] When the limiting circular plate 505 loses its restraining force, the compressed return spring coil 507 drives the rotating rod 502 to rotate, and drives the mounting round block 508 to rotate inside the mounting round frame 506, thereby improving the stability of the rotating rod 502 and the limiting circular plate 505 during rotation. When the limiting circular plate 505 rotates, the round ball at the bottom end of the limiting block 702 rotates on the upper end of the limiting circular plate 505, thereby reducing the friction during the rotation. When the limiting block 702 rotates to the position of the limiting recess 701, the limiting block 702 will be engaged with the limiting recess 701, and the limiting circular plate 505 and the rotating rod 502 will be limited and fixed, thereby increasing the stability during the receiving process. When the circular plate 503 rotates, it will drive the surrounding mounting rods 509 to rotate, and drive the bottom frame 510 and the detection cup 504 to rotate. When the processed material falls into the detection cup 504, the processed material and the detection cup 504 will be When the bottom frame 510 is moved, the rotating block 512 is driven to slide inside the annular sliding frame 511, and the rotating block 512 is driven to rotate by friction. When the rotating block 512 rotates, the bottom frame 510 and the detection cup 504 are driven to rotate, and when the detection cup 504 rotates, the annular mounting bar 514 is driven to slide inside the annular mounting rail 513, thereby increasing the stability and flexibility of the bottom frame 510 and the detection cup 504 when they rotate. When the collecting bucket 501 rotates, the vibration rods 11 on both sides are driven to rotate. When the vibration rods 11 rotate to the position of the mounting rods 509, the bottom ends of the vibration rods 11 are in contact with and collide with the outside of the mounting rods 509, so that the vibration rods 11 generate vibration force, and the elasticity generated by the elastic rods makes the vibration frequency of the vibration rods 11 longer. When the vibration rods 11 vibrate, they drive the vibration sheet 12 to vibrate at the bottom end of the inner cavity of the detection cup 504, so that the detection liquid and the material vibrate.
