Description

Technical Field

[0001] This invention relates to the field of antibacterial powder processing technology, specifically to an antibacterial powder production and processing equipment. Background Technology

[0002] Antibacterial powder is a type of functional powder material that has the activity of inhibiting or killing microorganisms such as bacteria and mold. The core is to achieve antibacterial function through the composite form of active ingredients and carriers. It can be widely used in many fields such as industry, medicine, and food.

[0003] During the pulverization process, existing industrial-grade antibacterial powders produce fine powder. Inside the pulverizing equipment, the collision of excessively fine powder with the equipment can cause temperature rise. Excessively fine powder can lead to agglomeration of nanoparticles, decomposition of heat-sensitive antibacterial components due to high temperatures, and contamination of the powder by impurities, making subsequent sieving difficult. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an antibacterial powder production and processing equipment, which solves the problems that industrial-grade antibacterial powder produces very fine powder during the pulverization process. This fine powder leads to agglomeration of nanoparticles, decomposition of heat-sensitive antibacterial components due to high temperatures, and contamination of the powder by impurities, making subsequent sieving difficult.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an antibacterial powder production and processing equipment, including a support frame, a crushing barrel fixedly installed on the support frame, a feeding pipe provided on the crushing barrel, an electric screw feeder installed inside the feeding pipe, a discharge hopper installed on the feeding pipe and a sealing cover provided on the discharge hopper, and a crushing mechanism for crushing materials and a sorting mechanism for removing excessively fine powders are provided inside the crushing barrel; The crushing mechanism includes a crushing bucket fixedly installed inside the crushing barrel, a crushing roller slidably installed inside the crushing mechanism, a support plate fixedly installed at the top of the crushing roller, a plurality of drive push rods fixedly installed on the surface of the crushing barrel, the support plate being fixedly connected to the output end of the drive push rods, and a drive motor being fixedly installed on the support plate, and the crushing roller being fixedly connected to the output shaft of the drive motor. The sorting mechanism includes a conveying pipe fixedly installed on the crushing barrel. A collection box with a sealed door is installed on the outer surface of the crushing barrel. The collection box is provided with an exhaust pipe and a connecting pipe. The collection box and the crushing barrel are connected by the connecting pipe. A filter screen is installed inside the collection box at the position between the exhaust pipe and the connecting pipe. A filter screen is installed between the crushing hopper and the crushing barrel.

[0006] By adopting the above technical solution, and by setting up a crushing hopper, crushing roller, support plate, drive motor, and drive push rod, the drive motor drives the crushing roller to rotate. The rotation of the crushing roller, in conjunction with the crushing hopper, can achieve the initial crushing of antibacterial materials. The size of the crushing cavity between the crushing hopper and the crushing roller decreases from top to bottom, which can perform graded crushing of materials and avoid the problem of large pieces of material blocking and jamming. The drive push rod can drive the support plate to move up and down. The movement of the support plate will drive the crushing roller to move up and down synchronously, realizing the adjustment of the position of the crushing roller. The movement of the crushing roller position can adjust the size of the crushing cavity, realize the crushing work of different specifications, and meet the needs of different crushing specifications.

[0007] Preferably, the crushing barrel is provided with a primary screening mechanism, which includes an arc-shaped bracket fixedly installed on the inner wall of the crushing barrel. Two coarse screens are rotatably installed inside the arc-shaped bracket. The outer wall of the coarse screen is provided with an arc-shaped surface that cooperates with the inner wall of the arc-shaped bracket. A control motor is fixedly installed at the bottom of the lower coarse screen, and the upper coarse screen is fixedly connected to the output shaft of the control motor.

[0008] Preferably, a connecting shell is installed at the end of the conveying pipe, a rotating shaft is rotatably installed on the connecting shell, a plurality of drive plates whose outer surfaces are in contact with the inside of the connecting shell are fixedly installed on the outer surface of the rotating shaft, two eccentric cams are eccentrically installed on the outer surface of the rotating shaft, the two eccentric cams are staggered one above the other, and an exhaust port is opened at the top of the connecting shell directly opposite the coarse screen.

[0009] Preferably, the bottom of the crushing barrel is provided with a secondary screening mechanism, which includes a screening box. The screening box has a feed inlet, and the discharge pipe of the crushing barrel is fixedly connected to the feed inlet of the screening box. The screening box is provided with a screening frame, and multiple fine screens are slidably and detachably installed inside the screening frame. The mesh size of the multiple fine screens decreases from top to bottom.

[0010] Preferably, drive shafts are rotatably mounted on both sides of the screening box, drive turntables are fixedly mounted on opposite ends of the two drive shafts, push rods are eccentrically mounted on opposite sides of the two drive turntables, guide frames are fixedly mounted on both sides of the screening frame, the push rod shaft is slidably disposed inside the guide frame, a rotary motor is fixedly mounted on the side of the screening box, and the end of the drive shaft is fixedly connected to the output shaft of the rotary motor.

[0011] Preferably, a wedge block one is fixedly installed on one inner wall of the screening box, a wedge block two that cooperates with the wedge block one is installed on the side of the screening frame, and a plurality of elastic elements are installed on the other inner wall of the screening box, and a contact plate that fits against the surface of the screening frame is fixedly installed at the end of the elastic element.

[0012] Preferably, a rotating rod is rotatably mounted on the feed pipe of the crushing barrel, and the rotating rod is rotatably mounted on the screening box. Several feed plates are fixedly mounted on the outer surface of the rotating rod inside the feed pipe of the crushing barrel. Synchronous pulleys are fixedly mounted on both ends of the rotating rod and on the outer surfaces of the two drive shafts. The two synchronous pulleys on the same side are connected by a synchronous belt.

[0013] Preferably, a material pump is fixedly installed on the outer surface of the crushing barrel, the material pump's suction pipe penetrates the outer wall of the crushing barrel and is fixedly installed on the arc-shaped bracket, and the material pump's discharge pipe penetrates the top of the crushing barrel and extends into the interior of the crushing barrel.

[0014] Preferably, a connecting rod is installed at the bottom end of the crushing roller, and a dispersing wheel is fixedly installed at the bottom end of the connecting rod.

[0015] Preferably, an annular cleaning block is rotatably mounted on the upper surface of the inner wall of the crushing barrel, and the cleaning block is in contact with the outer surface of the crushing roller.

[0016] Working principle: Place the material to be crushed inside the hopper, turn on the electric rotating screw feeder, and transport the crushed material through the conveying pipe to the crushing barrel. The crushed material falls into the crushing hopper. The drive motor is turned on and drives the crushing roller to rotate. As the crushing roller rotates, it drives the dispersing wheel to rotate through the connecting rod. The rotation of the dispersing wheel can disperse the falling crushed material and make it fall evenly on the surface of the coarse screen, helping it to pass through the screen quickly. The rotation of the crushing roller, in conjunction with the crushing hopper, achieves the initial crushing of the antibacterial material. The control activates the drive push rod, which drives the support plate to move up and down. As the support plate moves, it drives the crushing roller to move up and down synchronously, thus adjusting the position of the crushing roller. The movement of the crushing roller position can adjust the size of the crushing cavity, enabling crushing of different specifications and meeting the needs of different crushing specifications. The crushed material falls onto a coarse screen, and low-temperature nitrogen gas is supplied into the crushing chamber through a conveying pipe using external equipment. This effectively avoids the problem of excessive heat generated by the friction and collision between the crusher blades and the material during mechanical crushing, which would cause the temperature inside the chamber to rise. At the same time, it can also prevent the antibacterial ingredients from being deactivated due to high temperatures. The gas can blow the finer powder upwards to achieve the sorting process. After sorting, the finer powder enters the collection box through filter screen one and filter screen two, thus completing the fine powder processing. Turning on the control motor drives the upper coarse screen to rotate. The mesh size of the upper coarse screen overlaps with that of the lower coarse screen, allowing adjustment of the mesh size through which the crushed material can pass. The specifications of the primary screen can be adjusted according to different usage requirements. During the low-temperature nitrogen transport process, the drive plate can be driven to rotate. The rotation of the drive plate drives the rotating shaft to rotate synchronously. During the rotation of the rotating shaft, the eccentric cam rotates eccentrically. The two eccentric cams move alternately up and down, causing the coarse screen to swing repeatedly inside the arc-shaped bracket, which can improve the screening efficiency and avoid the accumulation of large pieces of material that cause blockage. After screening, the crushed material falls into the screening frame. The control starts the rotary motor, which drives the drive shaft to rotate. The rotation of the drive shaft drives the drive turntable to rotate synchronously. The rotation of the drive turntable drives the push rod to follow the eccentric movement. During the movement of the push rod, it slides inside the guide frame, driving the guide frame to move the screening frame up and down. The movement of the screening frame drives the fine screen inside to follow the movement, realizing the up and down vibration screening of the fine screen. As the screening frame moves up and down, it drives the second wedge block to move up and down synchronously. The second wedge block moves up and down until it contacts the first wedge block, which drives the screening frame to move laterally. Under the action of the elastic element and the contact plate, the screening frame can be driven to return to its original position laterally, realizing the lateral reciprocating motion of the screening frame. This allows the screening frame to vibrate up and down while vibrating laterally, thus completing the screening of the crushed material. Turning on the pump allows larger pieces of material to be extracted after crushing and fed back into the crushing hopper for secondary crushing.

[0017] This invention provides an antibacterial powder production and processing equipment. It has the following beneficial effects: 1. This invention, by setting up a conveying pipe, a collection box, filter screen one, and filter screen two, utilizes external equipment to deliver low-temperature nitrogen gas into the crushing barrel through the conveying pipe. This effectively avoids the problem of excessive heat generated by the friction and collision between the crusher blades and the material during mechanical crushing, which leads to an increase in the temperature inside the chamber. At the same time, it can prevent the antibacterial components from becoming ineffective due to high temperatures. The gas can blow the finer powder upwards to achieve sorting. After sorting, the finer powder enters the collection box through filter screen one and filter screen two, thus realizing the processing of the finer powder.

[0018] 2. By setting up a rotating shaft, a drive plate, and an eccentric cam, this invention can drive the drive plate to rotate during the low-temperature nitrogen conveying process. The rotation of the drive plate drives the rotating shaft to rotate synchronously. During the rotation of the rotating shaft, the eccentric cam rotates eccentrically. The two eccentric cams move alternately up and down, causing the coarse screen to swing repeatedly inside the arc-shaped bracket, which can improve the screening efficiency and avoid the accumulation of large pieces of material that cause blockage.

[0019] 3. This invention utilizes a rotary motor, a drive shaft, a drive turntable, a push rod, and a guide frame. The rotary motor drives the drive shaft to rotate, which in turn drives the drive turntable to rotate synchronously. The drive turntable then drives the push rod to move eccentrically. During its movement, the push rod slides inside the guide frame, causing the guide frame to move the screening frame up and down. The movement of the screening frame then causes the fine screen inside to move accordingly, thus achieving the up-and-down vibration screening of the fine screen and improving screening efficiency.

[0020] 4. This invention, by setting up an elastic element, a contact plate, a wedge block one, and a wedge block two, allows the screening frame to move up and down simultaneously, driving the wedge block two to move up and down synchronously. When the wedge block two moves up and down until it contacts the wedge block one, it drives the screening frame to move laterally. Under the action of the elastic element and the contact plate, the screening frame can be driven to return to its original position laterally, realizing the lateral reciprocating motion of the screening frame. This allows the screening frame to vibrate up and down while vibrating laterally, further improving the screening effect. Attached Figure Description

[0024] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides an antibacterial powder production and processing equipment, including a support frame 1, a crushing barrel 2 fixedly installed on the support frame 1, a feeding pipe 3 provided on the crushing barrel 2, an electric screw feeder 4 installed inside the feeding pipe 3, a discharge hopper 5 installed on the feeding pipe 3 and a sealing cover provided on the discharge hopper 5, a crushing mechanism 6 for crushing materials and a sorting mechanism 7 for removing excessively fine powder inside the crushing barrel 2. The crushing mechanism 6 includes a crushing bucket 601 fixedly installed inside the crushing barrel 2, a crushing roller 602 slidably installed inside the crushing mechanism 6, a support plate 603 fixedly installed at the top of the crushing roller 602, a plurality of drive push rods 604 fixedly installed on the surface of the crushing barrel 2, the support plate 603 is fixedly connected to the output end of the drive push rods 604, and a drive motor 605 is fixedly installed on the support plate 603. The crushing roller 602 is fixedly connected to the output shaft of the drive motor 605. By configuring a crushing hopper 601, a crushing roller 602, a support plate 603, a drive motor 605, and a drive push rod 604, the drive motor 605 drives the crushing roller 602 to rotate. The rotation of the crushing roller 602, in conjunction with the crushing hopper 601, enables the initial crushing of antibacterial materials. The size of the crushing cavity between the crushing hopper 601 and the crushing roller 602 decreases from top to bottom, allowing for graded crushing of materials and preventing large pieces of material from clogging or jamming. The drive push rod 604 drives the support plate 603 to move up and down. Simultaneously, the movement of the support plate 603 drives the crushing roller 602 to move up and down synchronously, allowing for adjustment of the position of the crushing roller 602. The movement of the crushing roller 602 adjusts the size of the crushing cavity, enabling crushing of different specifications to meet various crushing requirements.

[0025] Furthermore, the sorting mechanism 7 includes a conveying pipe 701 fixedly installed on the crushing barrel 2. A collection box 706 with a sealed door is installed on the outer surface of the crushing barrel 2. The collection box 706 is provided with an exhaust pipe 708 and a connecting pipe 707. The collection box 706 is connected to the crushing barrel 2 through the connecting pipe 707. A filter screen 709 is installed inside the collection box 706 at the position between the exhaust pipe 708 and the connecting pipe 707. A filter screen 710 is installed between the crushing hopper 601 and the crushing barrel 2.

[0026] By setting up a conveying pipe 701, a collection box 706, a filter screen 1 709, and a filter screen 2 710, low-temperature nitrogen gas is supplied to the inside of the crushing barrel 2 through the conveying pipe 701 using external equipment. This effectively avoids the problem of the large amount of heat generated by the friction and collision between the crusher blades and the material during mechanical crushing, which would cause the temperature inside the chamber to rise. At the same time, it can also prevent the antibacterial components from being deactivated due to high temperature. The gas can blow the finer powder upwards to achieve the sorting work. After sorting, the finer powder enters the collection box 706 through the filter screen 1 709 and the filter screen 2 710, thus realizing the processing of the finer powder.

[0027] For details, please refer to the appendix. Figure 4 - Appendix Figure 8 The crushing barrel 2 is equipped with a primary screening mechanism 8. The primary screening mechanism 8 includes an arc-shaped bracket 801 fixedly installed on the inner wall of the crushing barrel 2. Two coarse screens 803 are rotatably installed inside the arc-shaped bracket 801.

A control motor 802 is fixedly installed at the bottom of the lower coarse screen 803, and the upper coarse screen 803 is fixedly connected to the output shaft of the control motor 802.

[0028] By setting a coarse screen 803 and a control motor 802, the control motor 802 drives the upper coarse screen 803 to rotate. The mesh size of the upper coarse screen 803 overlaps with that of the lower coarse screen 803, which can adjust the mesh size through which the crushed material can pass. According to different usage needs, the specifications of the primary screen can be adjusted, thereby improving the applicability.

[0029] For details, please refer to the appendix. Figure 3 and attached Figure 4 A connecting housing 702 is installed at the end of the conveying pipe 701. A rotating shaft 705 is rotatably installed on the connecting housing 702.

An exhaust port is opened at the top of the connecting housing 702, directly opposite the coarse screen 803.

[0030] By setting up a rotating shaft 705, a drive plate 704, and an eccentric cam 703, the drive plate 704 can be driven to rotate during the low-temperature nitrogen conveying process. The rotation of the drive plate 704 drives the rotating shaft 705 to rotate synchronously. During the rotation of the rotating shaft 705, the eccentric cam 703 is driven to rotate eccentrically. The two eccentric cams 703 move alternately up and down, driving the coarse screen 803 to swing repeatedly inside the arc-shaped bracket 801, which can improve the screening efficiency and avoid the accumulation of large pieces of broken material that cause blockage.

[0031] For details, please refer to the appendix. Figure 7 and attached Figure 8 The bottom of the crushing barrel 2 is provided with a secondary screening mechanism 9. The secondary screening mechanism 9 includes a screening box 901. The screening box 901 has a feed inlet, and the discharge pipe of the crushing barrel 2 is fixedly connected to the feed inlet of the screening box 901. The screening box 901 is provided with a screening frame 902. Multiple fine screens 903 are slidably and detachably installed inside the screening frame 902. The mesh size of the multiple fine screens 903 decreases from top to bottom.

[0032] By setting up a screening box 901 and a fine screen 903, the fine screen 903 can be used to perform secondary screening of the crushed material after the initial screening, separating the crushed material of different specifications together, making it easier for subsequent staff to pick up the crushed material of different specifications.

[0033] For details, please refer to the appendix. Figure 7 - Appendix Figure 10Both sides of the screening box 901 are rotatably mounted with drive shafts 906. Drive turntables 905 are fixedly mounted on opposite ends of the two drive shafts 906. Push rods 915 are eccentrically mounted on opposite sides of the two drive turntables 905. Guide frames 914 are fixedly mounted on both sides of the screening frame 902. The push rods 915 are slidably disposed inside the guide frames 914. A rotary motor 904 is fixedly mounted on the side of the screening box 901. The ends of the drive shafts 906 are fixedly connected to the output shaft of the rotary motor 904.

[0034] By setting up a rotary motor 904, a drive shaft 906, a drive turntable 905, a push rod 915, and a guide frame 914, the rotary motor 904 drives the drive shaft 906 to rotate. The rotation of the drive shaft 906 drives the drive turntable 905 to rotate synchronously. The rotation of the drive turntable 905 drives the push rod 915 to move eccentrically. During the movement of the push rod 915, it slides inside the guide frame 914, which drives the guide frame 914 to move the screening frame 902 up and down. The movement of the screening frame 902 drives the fine screen 903 inside to move accordingly, realizing the up and down vibration screening of the fine screen 903 and improving the screening efficiency.

[0035] For details, please refer to the appendix. Figure 7 and attached Figure 8 A wedge block 911 is fixedly installed on one side of the inner wall of the screening box 901. A wedge block 912 that cooperates with the wedge block 911 is installed on the side of the screening frame 902. A plurality of elastic elements 913 are installed on the other side of the inner wall of the screening box 901, and a contact plate 916 that fits against the surface of the screening frame 902 is fixedly installed at the end of the elastic element 913.

[0036] By setting up an elastic element 913, a contact plate 916, a first wedge block 911, and a second wedge block 912, the screening frame 902 moves up and down while simultaneously driving the second wedge block 912 up and down synchronously. The second wedge block 912 moves up and down until it contacts the first wedge block 911, driving the screening frame 902 to move laterally. Under the action of the elastic element 913 and the contact plate 916, the screening frame 902 can be driven to return to its original position laterally, realizing the lateral reciprocating motion of the screening frame 902. This allows the screening frame 902 to vibrate up and down while vibrating laterally, further improving the screening effect.

[0037] For details, please refer to the appendix. Figure 6 A rotating rod 907 is rotatably mounted on the feed pipe of the crushing barrel 2, and the rotating rod 907 is rotatably mounted on the screening box 901. Several feed plates 910 are fixedly mounted on the outer surface of the rotating rod 907 inside the feed pipe of the crushing barrel 2. Synchronous pulleys 908 are fixedly mounted on both ends of the rotating rod 907 and on the outer surface of the two drive shafts 906. The two synchronous pulleys 908 on the same side are connected by a synchronous belt 909.

[0038] By setting up a rotating rod 907, a feeding plate 910, a synchronous pulley 908, and a synchronous belt 909, the rotating shaft 906 is driven to rotate, and the synchronous belt 909 and the synchronous pulley 908 drive the crushing roller 602 to rotate. The rotation of the rotating rod 907 drives the feeding plate 910 to rotate. The rotation of the feeding plate 910 can agitate the falling crushed material, increase the feeding speed, and avoid clogging the feeding pipe.

[0039] For details, please refer to the appendix. Figure 2 A material pump 10 is fixedly installed on the outer surface of the crushing barrel 2. The material pump 10's suction pipe passes through the outer wall of the crushing barrel 2 and is fixedly installed on the arc-shaped bracket 801. The material pump 10's discharge pipe passes through the top of the crushing barrel 2 and extends into the interior of the crushing barrel 2.

[0040] By setting up a material pump 10, larger pieces of crushed material can be extracted and fed back into the crushing hopper 601 for secondary crushing, ensuring the size of the crushed material and avoiding excessive size from affecting subsequent use.

[0041] For details, please refer to the appendix. Figure 10 A connecting rod 606 is installed at the bottom end of the crushing roller 602, and a dispersing wheel 607 is fixedly installed at the bottom end of the connecting rod 606.

[0042] By setting up a connecting rod 606 and a dispersing wheel 607, the crushing roller 602 rotates while the dispersing wheel 607 rotates through the connecting rod 606. The rotation of the dispersing wheel 607 can disperse the falling crushed material, so that it falls evenly on the surface of the coarse screen 803, helping it to pass through the screen quickly.

[0043] For details, please refer to the appendix. Figure 5 and attached Figure 10 A ring-shaped cleaning block 608 is rotatably installed on the upper surface of the inner wall of the crushing barrel 2, and the cleaning block 608 is in contact with the outer surface of the crushing roller 602.

[0044] By setting the cleaning block 608, the outer surface of the crushing roller 602 can be cleaned during the up-and-down movement of the crushing roller 602, preventing the crushing roller 602 from carrying the debris outside the crushing barrel 2 during the up-and-down movement, and at the same time preventing the debris from getting stuck in the gap of the crushing roller 602 and affecting the crushing effect.

[0045] Working principle: Place the material to be crushed inside the feeding hopper 5, turn on the electric rotating screw feeder, and transport the crushed material through the conveying pipe 3 to the crushing bucket 2. The crushed material falls into the crushing bucket. The drive motor 605 is turned on, which drives the crushing roller 602 to rotate. While the crushing roller 602 is rotating, it drives the dispersing wheel 607 to rotate through the connecting rod 606. The rotation of the dispersing wheel 607 can disperse the falling crushed material and make it fall evenly on the surface of the coarse screen 803, helping it to pass through the screen quickly. The rotation of the crushing roller 602 cooperates with the crushing hopper 601 to achieve the initial crushing of the antibacterial material. The control activates the drive push rod 604, which drives the support plate 603 to move up and down. While the support plate 603 moves, it drives the crushing roller 602 to move up and down synchronously, thereby adjusting the position of the crushing roller 602. The movement of the crushing roller 602 can adjust the size of the crushing cavity, achieving crushing of different specifications and meeting the needs of different crushing specifications. The crushed material falls onto the coarse screen 803. Low-temperature nitrogen gas is supplied to the crushing barrel 2 through the conveying pipe 701 using external equipment. This effectively avoids the problem of the temperature inside the chamber rising due to the large amount of heat generated by the friction and collision between the crusher blades and the material during mechanical crushing. At the same time, it can prevent the antibacterial ingredients from being deactivated due to high temperature. The gas can blow the finer powder upward to achieve the sorting work. After sorting, the finer powder enters the collection box 706 through the first filter screen 709 and the second filter screen 710, thus realizing the processing of the finer powder. Turning on the control motor 802 drives the upper coarse screen 803 to rotate. The mesh size of the upper coarse screen 803 overlaps with that of the lower coarse screen 803, which allows for adjustment of the mesh size through which the crushed material can pass. The specifications of the primary screen can be adjusted according to different usage requirements. During the low-temperature nitrogen transport process, the drive plate 704 can be driven to rotate. The rotation of the drive plate 704 drives the rotating shaft 705 to rotate synchronously. During the rotation of the rotating shaft 705, the eccentric cam 703 is driven to rotate eccentrically. The two eccentric cams 703 move alternately up and down, driving the coarse screen 803 to swing repeatedly inside the arc-shaped bracket 801, which can improve the screening efficiency and avoid the accumulation of large pieces of broken material that cause blockage. The sieved material falls into the screening frame 902. The control starts the rotary motor 904, which drives the drive shaft 906 to rotate. The rotation of the drive shaft 906 drives the drive turntable 905 to rotate synchronously. The rotation of the drive turntable 905 drives the push rod 915 to follow the movement eccentrically. During the movement of the push rod 915, it slides inside the guide frame 914, which drives the guide frame 914 to move the screening frame 902 up and down. The movement of the screening frame 902 drives the fine screen 903 inside to follow the movement, realizing the up and down vibration screening of the fine screen 903. While the screening frame 902 moves up and down, it drives the second wedge block 912 to move up and down synchronously. The second wedge block 912 moves up and down until it contacts the first wedge block 911, which drives the screening frame 902 to move laterally. Under the action of the elastic element 913 and the contact plate 916, the screening frame 902 can be driven to return to its original position laterally, realizing the lateral reciprocating motion of the screening frame 902. This allows the screening frame 902 to vibrate up and down while vibrating laterally, thus completing the screening of the crushed material. Turning on the material pump 10 can extract the larger pieces after crushing and send them back into the crushing hopper 601 for secondary crushing.
