Description

Technical Field

[0001] The utility model relates to the technical field of vibrating sieves, and particularly relates to a shock-type standard vibrating sieve machine. Background Technique

[0002] The shock-type standard vibrating sieve machine is a commonly used screening device in laboratories. It is widely used in experimental tests in industries such as coal quality analysis, geology, metallurgy, chemical engineering, scientific research, and cement. It can screen and analyze materials. Through the combined screening function of shaking and shock, it can efficiently screen materials, has the advantages of fast feeding and not easy to block, and is particularly suitable for the production and classification of diamond powder and super-hard materials;

[0003] For example, the Chinese utility model patent disclosed with the publication number CN218133330U: shock-type standard vibrating sieve machine. This application uses a pressing mechanism to press the sieve cover on the sieve box. The arc-shaped plate moves towards the sieve box under the drive of the driving member, so that the arc surface of the arc-shaped plate close to the sieve box abuts against the outer periphery of the sieve box, and the arc-shaped plate clamps the sieve box. It also controls the cylindrical block through the screw and cooperates with the sieve cover to press and fix the sieve box. When fixing the sieve box through the above structure, it is necessary to adjust and clamp multiple groups of arc-shaped plates outside the sieve box. At the same time, after clamping and fixing the sieve box through the arc-shaped plate, it is also necessary to rotate the screw downward to press the sieve cover, making the overall operation process cumbersome. In addition, when the number of sieve boxes used is different, the screw and the cylindrical block cannot be quickly adjusted up and down, which further increases the inconvenience of operating the sieve box fixation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shock-type standard vibrating sieve machine, which can effectively solve the problem that the sieve box cannot be fixed quickly in the existing technical solutions mentioned in the background technique, and the problem that the screw and the cylindrical block cannot be quickly adjusted adaptively when the number of sieve boxes used changes.

With the arrangement of the columns 14 and the connecting rods 15, the guide columns 5 can be installed more stably, thereby ensuring that the limiting mechanism 7 is adjusted more stably up and down;

[0030] Embodiment 2:

[0031] Refer to Figures 2-5, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a supporting block 16 is fixedly installed inside the installation box 8 between the two connecting beams 9, three first screw seats 17 are fixedly installed at the bottom of the installation box 8, a top cover 18 is inserted and installed in the installation box 8 at a position above the supporting block 16, a second screw seat 19 is fixedly installed at the center of the top of the top cover 18, and the top cover 18 is also fixedly connected to the installation box 8 by screws. Through the split-type top cover 18 and in cooperation with the open structure at the bottom of the connecting beam 9, it is convenient for the later disassembly, installation and maintenance of the whole device. A knob 20 is fixedly installed at the top of the adjusting screw rod 11, a fixing ring 21 is fixedly installed at the bottom of the adjusting screw rod 11, the adjusting screw rod 11 between the knob 20 and the pressing block 12 is threadedly connected in the knob 20, and the fixing ring 21 extends to a position below the installation box 8 through the through hole at the bottom of the installation box 8 by the adjusting screw rod 11 and is movably installed with a rubber pad 22. A rotating groove 23 is opened at the center of the top of the rubber pad 22, and the rubber pad 22 is rotatably installed on the fixing ring 21 through the rotating groove 23. With the help of the rubber pad 22, when the adjusting screw rod 11 rotates downward in the knob 20, the sieve plate cover can be tightly fixed. A fixing seat 24 is fixedly installed at the bottom of the connecting beam 9, a sleeve 25 is also fixedly installed on the connecting beam 9 on one side of the fixing seat 24, two jacks 26 are opened inside the sleeve 25, the ejector rod 10 is inserted and installed in one of the fixing seats 24 and the jack 26, and the side of the connecting beam 9 away from the installation box 8 is inserted and installed on the corresponding guide post 5 through the sleeve 25. The installation box 8 can be adjusted up and down between the three guide posts 5 through the connecting beam 9 and the sleeve 25, and in cooperation with the extrusion displacement of the pressing block 12 on the ejector rod 10, the position of the connecting beam 9 can be limited while the sieve plate cover is tightly fixed.

[0032] It should be noted that the present utility model is a shock-type standard vibrating sieve machine. When screening materials, the sieve boxes can be stacked on the tray 6 in sequence. Then, a sieve cover is placed on the top of the sieve box at the uppermost position. Then, the knob 20 can be rotated counterclockwise, so that the knob 20 drives the adjusting screw 11 to rotate upward in the second screw seat 19. Thus, the adjusting screw 11 drives the pressing block 12 to move upward, so that the inclined surface outside the pressing block 12 is separated from one end of the three ejector rods 10, and further releases the pressure on the three ejector rods 10. Thus, the installation box 8 can be slowly moved downward through the knob 20, the adjusting screw 11 and the second screw seat 19, and the bottom of the rubber pad 22 contacts the top of the sieve cover. Subsequently, the knob 20 is rotated clockwise, so that the knob 20 drives the adjusting screw 11 to rotate downward in the second screw seat 19, and at the same time drives the pressing block 12 and the rubber pad 22 to move downward. Thus, after the rubber pad 22 abuts against the top of the sieve cover, it gradually drives the top cover 18 and the top cover 18 to move upward for a certain process. At this time, the adjusting screw 11 drives the pressing block 12 to squeeze one end of the three ejector rods 10 to one side respectively. Thus, the three ejector rods 10 move in the corresponding fixing seats 24 and jacks 26 toward the corresponding guide columns 5 respectively, and the other ends of the ejector rods 10 are pressed against the outside of the guide columns 5, and the position fixing of the connecting beam 9 and the installation box 8 can be completed. At this time, the adjusting screw 11 is continuously driven to rotate downward by the knob 20, so that the adjusting screw 11 drives the rubber pad 22 to be pressed against the sieve cover through the fixing ring 21, and thus the multi-layer sieve boxes are pressed tightly on the tray 6 by the conduction of force. Then, the vibration motor 3 can be started through the controller 2 and cooperate with the transmission mechanism in the machine case 1 to realize the screening of the materials in the sieve box.
