[0003] In the prior art, a sand and gravel screening machine is a device that screens and separates materials through a screen, and can separate materials of different particle sizes to meet the material particle size requirements of different fields. The vibrating sand and gravel screening machine uses a vibrating motor to make the material jump and roll on the surface of the screen. Fine materials can fall through the gaps on the screen, and large-size materials roll along the screen, thereby completing the material screening. During the long-term use of the sand and gravel screening machine, a large amount of fine materials and impurities will accumulate on the screen, which will affect the screening effect and the permeability of the screen, and the screen needs to be disassembled and cleaned. The traditional disassembly method of the screen requires the use of disassembly tools, which makes it difficult for operators to disassemble and clean the screen at the screening site at any time. Utility Model Content
[0004] The purpose of the utility model is to provide a sand and gravel screening machine that is easy to disassemble and clean, so as to solve the problem that the screen of the sand and gravel screening machine on the market is not easy to disassemble and clean at any time, as proposed in the above background technology.
[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a sand and gravel screening machine that is easy to disassemble and clean, comprising: a support frame body, a vibration spring, a connecting frame, a vibration motor and a screen.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the sand and gravel screening machine is easy to disassemble and clean, and when the threaded knob is reversed, it can slide with the mounting block in a direction away from the plug-in block, and when the threaded knob is rotated, the hemispherical block at its end can rotate. When the sand and gravel screening machine is in use, fine materials can pass through the screen and fall onto the guide plate, and roll from the inside of the guide plate to the outside of the support frame body through the inclined surface inside the guide plate. At this time, personnel can directly load the fine materials, and at the same time, the support frame body and the connecting frame will not interfere with personnel taking materials, thereby reducing a certain amount of labor for personnel.
[0013] 1. The sand and gravel screening machine is one of the indispensable and important equipment in the sand and gravel industry. During the use of the sand and gravel screening machine, once the screening effect of the screen becomes low, the screen needs to be disassembled and the material blocked on the screen needs to be cleaned. The traditional method of disassembling the screen is more troublesome, and it is not easy to disassemble and clean the screen at any time on the screening site. When the threaded knob is reversed, the thread can be slid with the mounting block in the direction away from the plug-in block, and when the threaded knob is rotated, the hemispherical block at its end can be rotated. When the plug-in block moves, its bottom end can slide out from the inside of the mounting block. When the plug-in block is removed from the inside of the connecting plate, the connecting plate can be rotated in the direction away from the screen. When the connecting plate moves, it can be rotated through the connecting column. When the six groups of connecting plates are no longer located above the screen, the screen can be removed from the inside of the connecting frame. The removed screen can be rinsed with water or brushed to ensure that the screen surface is clean and free of residue. This disassembly process does not require the use of tools, and the operation is simple and convenient. Personnel can disassemble and clean it at any time according to the actual situation of the screen at the screening site.
[0014] 2. There are many types and configurations of sand and gravel screening machines. After the traditional sand and gravel screening machine screens the material, the fine material will fall directly to the ground under the screen, making it difficult for personnel to quickly take out and load the material under the screen, and the support frame body and connecting frame will affect the speed of personnel taking the material. The guide plate can be pushed to the inner side of the support frame body so that the end of the docking block can be inserted into the connecting seat, and the longer end of the pin is inserted into the connecting seat, and the end of the pin can pass through the docking block through the through hole. When the end of the pin can pass through the connecting seat, the shorter end of the pin can be magnetically attracted to the magnetic block. When the sand and gravel screening machine is in use, the fine material can pass through the screen and fall onto the guide plate, and roll from the inside of the guide plate to the outside of the support frame body through the inclined surface inside the guide plate. At this time, personnel can directly load the fine material, and at the same time, the support frame body and the connecting frame will not interfere with the personnel taking the material, thereby reducing a certain amount of labor for the personnel.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1-Figure 4 It can be seen that the utility model provides a technical solution: a sand and gravel screening machine that is easy to disassemble and clean, comprising: a support frame body 1, a vibration spring 2, a connecting frame 3, a vibration motor 4 and a screen 5. The top of the support frame body 1 is equipped with a vibration spring 2, the top of the vibration spring 2 is connected to the connecting frame 3, the top of the connecting frame 3 is equipped with a vibration motor 4, the inner side of the connecting frame 3 is equipped with a screen 5, a connecting block 6, which is welded to the front and rear of the connecting frame 3 respectively, the top of the connecting block 6 is connected to a connecting column 7, the outer side of the connecting column 7 is rotated The rotary connection is provided with a connecting plate 8, and a plug-in block 9 is inserted into the interior of the connecting plate 8. The surface of the screen 5 near the plug-in block 9 is connected to a mounting block 10. The internal thread of the mounting block 10 is connected to a threaded knob 11, and the end of the threaded knob 11 is welded with a hemispherical block 12. The shape of the mounting block 10 is U-shaped, and a plug-in structure is formed between the plug-in block 9 and the mounting block 10. Six groups of connecting blocks 6 are symmetrically arranged front and back about the center of the connecting frame 3. A card slot matching the size of the hemispherical block 12 is provided on the side of the plug-in block 9 near the threaded knob 11.
[0023] In specific implementation, the sand and gravel screening machine is one of the important equipment that is indispensable in the sand and gravel industry. During the use of the sand and gravel screening machine, once the screening effect of the screen 5 becomes low, it is necessary to disassemble the screen 5 and clean the materials blocked on the screen 5. The traditional way of disassembling the screen 5 is more troublesome, and it is not easy to disassemble and clean the screen 5 at any time on the screening site. When the screen 5 is blocked more seriously, the equipment can be shut down first, and the six groups of threaded knobs 11 can be reversed one by one. When the threaded knob 11 is reversed, it can be turned away from the plug-in block 9 and the installation When the mounting block 10 slides threadedly and the threaded knob 11 is rotated, the hemispherical block 12 at its end can be rotated. When the hemispherical block 12 is moved out from the inside of the plug-in block 9, the hemispherical block 12 no longer squeezes the plug-in block 9, so that the plug-in block 9 can be pulled away from the screen 5. When the plug-in block 9 moves, its bottom end can slide out from the inside of the mounting block 10. When the plug-in block 9 is moved out from the inside of the connecting plate 8, the connecting plate 8 can be rotated away from the screen 5. When the connecting plate 8 moves, it can be rotated through the connecting column 7.
[0024] See Figure 1-Figure 4 It can be seen that when the six groups of connecting plates 8 are no longer located above the screen 5, the screen 5 can be removed from the inside of the connecting frame 3. The removed screen 5 can be rinsed with water or brushed to ensure that the surface of the screen 5 is clean and free of residue. This disassembly process does not require the aid of tools, and the operation is simple and convenient. Personnel can disassemble and clean the screen 5 at any time according to the actual situation of the screening site.
[0025] See Figure 1 and Figure 5It can be seen that a connecting seat 13 is welded on the inner side of the support frame body 1, a magnetic block 14 is embedded and installed on the surface of the connecting seat 13, a pin 15 is inserted through the inside of the connecting seat 13, and a guide plate 16 is provided on the inner side of the support frame body 1. A support column 17 is welded to the bottom of the guide plate 16, and a docking block 18 is welded on the side of the support column 17 close to the connecting seat 13. A through hole 19 is opened through the inside of the docking block 18, and the size of the through hole 19 matches the size of the pin 15.
[0026] During specific implementation, the models and configurations of sand and gravel screening machines are varied. After the traditional sand and gravel screening machine screens the material, the fine material will fall directly on the ground below the screen 5. It is difficult for personnel to quickly take out and load the material under the screen 5, and the support frame body 1 and the connecting frame 3 will affect the speed of personnel taking materials. The guide plate 16 can be pushed to the inner side of the support frame body 1 so that the end of the docking block 18 can be inserted into the connecting seat 13, and the guide plate 16 can be supported by the support column 17. At this time, the guide plate 16 is located directly below the screen 5, and the longer end of the pin 15 is inserted into the connecting seat 13, and the end of the pin 15 can pass through the docking block 18 through the through hole 19. When the end of the pin 15 can pass through the connecting seat 13, the shorter end of the pin 15 can be magnetically attracted to the magnetic block 14, so that the pin 15 is not easy to loosen.
[0027] See Figure 1 and Figure 5 It can be seen that when the sand and gravel screening machine is in use, fine materials can fall onto the guide plate 16 through the screen 5, and roll from the inside of the guide plate 16 to the outside of the support frame body 1 through the inclined surface inside the guide plate 16. At this time, personnel can directly load the fine materials. At the same time, the support frame body 1 and the connecting frame 3 will not interfere with the personnel's material retrieval, thereby reducing the personnel's workload to a certain extent.
[0028] In summary, when using the sand and gravel screening machine that is easy to disassemble and clean, the equipment can be shut down first, and the six groups of threaded knobs 11 can be reversed one by one. When the threaded knob 11 is reversed, it can be threadedly slid with the mounting block 10 in the direction away from the plug-in block 9, and when the threaded knob 11 is rotated, the hemispherical block 12 at its end can be rotated, and the removed screen 5 can be rinsed with water or brushed to ensure that the surface of the screen 5 is clean and free of residue. This disassembly process does not require the aid of tools, and the operation is simple and convenient. Personnel can disassemble and clean the screen 5 at any time according to the actual situation of the screening site. When the sand and gravel screening machine is in use, fine materials can fall onto the guide plate 16 through the screen 5 and roll from the inside of the guide plate 16 to the outside of the support frame body 1 through the inclined surface inside the guide plate 16. At this time, personnel can directly load the fine materials. At the same time, the support frame body 1 and the connecting frame 3 will not interfere with the personnel taking the materials, thereby reducing a certain amount of labor for the personnel.
