The turntable 3 is circular and is provided with a plurality of through holes which are circularly arrayed around the center line of the turntable 3. A bolt is arranged in each through hole and screwed in a threaded hole in the bottom surface of the vibrating table 21, and when the vibrating motor 24 needs to be adjusted, the turntable 3 is turned down and rotated by a proper angle, so that the installation angle of the vibrating motor 24 can be adjusted.
Referring to fig. 3 and 4, in the fixing portion, the frame 11 is formed by welding channel steel or i-steel and other profiles, and is generally rectangular. The number of the lower guide sleeves 12 is four, and the lower guide sleeves are respectively welded on four corners of the top surface of the frame 11. The vibration table 21 is formed by welding channel steel or I-steel and other profiles, the shape of the vibration table is the same as that of the rack 11, and the number of the upper guide sleeves 22 is four, and the four upper guide sleeves are respectively welded at four corners of the bottom surface of the vibration table 21. The upper guide sleeves 22 correspond to the lower guide sleeves 12 one by one, and two ends of the spring 13 are respectively sleeved on the outer walls of the upper guide sleeves 22 and the lower guide sleeves 12.
The guide post 23 is connected with the vibration table 21 by screw thread, and the lower end of the guide post passes through the upper guide sleeve 22 and then extends into the lower guide sleeve 12. The bottom surface of the guide post 23 is further provided with a blind hole 25, an auxiliary spring 26 is placed in the blind hole 25, and two ends of the auxiliary spring 26 are respectively fixed on the bottom surface of the blind hole 25 and the frame 11.
The top surface of the vibration table 21 is welded with a flanging 5, and the flanging 5 is made of strip steel or angle steel. The partition plate 41 is placed in the turned-over edge 5, a separation net 42 is laid on the partition plate, and the height of the separation net 42 is lower than that of the turned-over edge 5. The partition plate 41 is preferably made of steel grating, which is high in strength and convenient to cut.
Referring to fig. 5, the vibration table 21 is provided with a sewage draining hole 71, and the sewage draining hole 71 is located in the area enclosed by the flanging 5. The blow-off hole 71 is provided with a plug 72, and the plug 72 is formed by welding two plates with the same shape as the blow-off hole 71 or processing a thick plate. The two plates have the same shape, but one plate is smaller than the other plate, the smaller plate is positioned in the sewage hole 71, and the larger plate is positioned on the vibrating table 21, so that the sewage hole 71 can be blocked, and the sewage hole 71 can be prevented from being shaken apart in the vibrating process.
The implementation principle of the embodiment is as follows:
the sample to be detected is placed on the screen 42, and then the vibration motor 24 is started, and the vibration motor 24 starts to drive the vibration table 21 to vibrate. In this process, the spring 13 is continuously extended or shortened to provide support for the vibration table 21.
During the shaking process, the debris on the sample falls into the spacer 41 below the spacer 42. And after the vibration is finished, taking down the sample piece and sending the sample piece to detection. The partition plate 41, the partition net 42 and the plug 72 on the sewage discharge hole 71 on the vibration table 21 are removed, the debris on the vibration table 21 is swept into the sewage discharge hole 71, and the debris is discharged from the sewage discharge hole 71. After cleaning, the partition plate 41, the partition net 42 and the plug 72 are put back.
