Description

Technical Field

[0001] The utility model relates to the technical field of slap-type vibrating screen machines, in particular to a slap-type vibrating screen machine. Background Art

[0002] The slap vibrating screen is sometimes also called the slap standard vibrating screen. The slap vibrating screen is a common laboratory equipment, mainly used for particle size analysis, grading, screening and other tasks of various powders and granular materials. The slap vibrating screen is mainly composed of three parts, namely the base, the screen and the transmission device. Its working principle is to drive the screen with a motor to produce a vibration of a specific frequency and amplitude, and cooperate with the reciprocating motion of the slapping mechanism to make the material on the screen be continuously slapped and vibrated, thereby realizing efficient screening and grading of the material.

[0003] Expanded clay sand is a granular material made from clay as the main raw material through a series of processes including batching, balling, high-temperature firing, crushing, screening, etc. When expanded clay sand needs to be screened after granulation, a slap-type vibrating screen machine is often required.

[0004] The current slap-type vibrating screen can adjust the height of the bottom tray according to the number of screen layers, but when adjusting the height, it is necessary to manually release the restriction first, then move the hand support up and down, and after changing to the desired position, use the fastening wire to tighten the limit, which is more troublesome to operate. Secondly, some of the existing slap-type vibrating screens have rubber or silicone columns inserted on the slap hammers. The rubber or silicone columns are used to contact the screen to reduce damage to the screen, but when the rubber or silicone columns need to be replaced, it is difficult to remove them quickly, which is time-consuming and labor-intensive.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Figure 1 and Figure 2 All of them are schematic diagrams of the overall structure of the utility model, and combined with Figure 3 As shown, the slapping type vibrating screen machine includes a base 1, a driving box 6 is installed on the rear side of the upper end surface of the base 1, a motor is installed in the base 1, an eccentric wheel is installed in the driving box 6, and a controller 7 is also installed on one side of the upper end surface of the base 1. A display screen and a start-stop switch are installed on the controller 7. The display screen can display the slapping time and number of times, and the start-stop switch is used to start and stop the machine. A movable support plate 2 is provided on the upper end surface of the base 1, and two vertical poles 3 are fixed on the movable support plate 2. A sleeve block 10 is provided on the outside of each vertical pole 3, and a tray 11 is connected between the two sleeve blocks 10. A sieve 5 is provided on the tray 11, and caps 4 are fixed to the upper ends of the two vertical poles 3, and a telescopic component is provided between the cap 4 and the sleeve block 10.

[0030] A striking arm 8 is installed above the driving box 6, and a striking hammer 9 is installed at the striking end of the striking arm 8. The striking hammer 9 includes a sleeve 16 and a silicone block 17. A slot 21 is opened on the lower end surface of the sleeve 16, and the silicone block 17 is inserted and matched with the slot 21. The lower end surface of the silicone block 17 protrudes downward from the lower end surface of the sleeve 16, and a pressing component is provided on the top of the sleeve 16, which is used to press down the silicone block 17 in the slot 21.

[0031] See also Figure 3 As shown, the pressing assembly includes:

[0032] A threaded barrel 18, the threaded barrel 18 is fixed to the top of the sleeve 16;

[0033] The threaded rod 19 is screwed into and penetrates the threaded barrel 18 , and the threaded rod 19 can penetrate the sleeve 16 .

[0034] A hand wheel 20 is mounted on the top end of the threaded rod 19 .

[0035] Through the above technical solution:

[0036] During specific use, the expanded clay sand to be screened is first added into the upper sieve 5, and then the controller 7 is used to start the motor. The motor drives the gear to change speed through the synchronous belt to rotate the main shaft. The main shaft drives the eccentric wheel to make the slide drive the sieve 5 to shake left and right, and at the same time drives the top rod gear to rotate, and hits the striking arm 8, and then uses the striking hammer 9 to hit the sieve 5 to complete the screening operation, and expanded clay sand of different particle sizes can be screened out.

[0037] According to the height of the sieves 5 with different layers, the telescopic assembly can be used to adjust the tray 11 to move up and down, so that the cover body at the top of the sieve 5 passes through the cover cap 4.

[0038] Secondly, when installing the silicone block 17, insert the silicone block 17 into the slot 21 so that the silicone block 17 can be installed in the sleeve 16. After repeated use of slapping, the silicone block 17 will be worn and deformed and affect the slapping effect. At this time, the silicone block 17 needs to be replaced. When replacing the silicone block 17, the hand wheel 20 can be used to rotate the threaded rod 19 that passes through the threaded tube 18 to move the threaded rod 19 downward. The silicone block 17 in the sleeve 16 can be pushed out by the bottom end of the threaded rod 19, and it is convenient and quick to take out.

[0039] Furthermore, mounting ears 15 are fixed to the bottom ends of both sides of the base 1 , and mounting holes are formed on the mounting ears 15 .

[0040] Specifically, the expansion bolt passes through the mounting hole on the mounting ear 15 to fix the mounting ear 15 on the ground, thereby ensuring the stability of the installation of the entire vibrating screen machine.

[0041] Among them, see Figure 1 and Figure 2 As shown, the telescopic assembly includes:

[0042] A first protrusion 12, the first protrusion 12 is fixed to the outer end of the sleeve block 10;

[0043] A second protrusion 13, the second protrusion 13 is fixed to the end of the cap 4;

[0044] The electric telescopic rod 14 is installed between the first convex block 12 and the second convex block 13 which are opposite to each other in the upper and lower directions. The electric telescopic rod 14 is electrically connected to the controller 7 .

[0045] Through the above technical solution:

[0046] When it is necessary to adjust the tray 11 to move up and down, it is only necessary to use the controller 7 to start the electric telescopic rod 14, and use the electric telescopic rod 14 between the first protrusion 12 and the second protrusion 13 to drive the tray 11 to move up and down, so as to ensure that the cover body at the top of the sieve 5 passes through the cover cap 4. There is no need to move it up with the hand support, and then use the fastening wire to tighten the limit, so that the up and down movement is convenient and labor-saving.

[0047] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
