Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the vibrating shaker comprises a base 2 for placing a standard sieve 1, a vibrating device 3 located below the base 2 and used for intermittently knocking the base 2, and three guide rods 4 fixedly connected to the upper surface of the base 2 and having circular cross sections, wherein each guide rod 4 is vertically arranged, and the three guide rods 4 are distributed on the base 2 in a semicircular shape; the vibrating shaker further comprises a connecting rod 5 fixedly connected among the three guide rods 4 and a three-fork type pressing rod 6 which slides up and down on the three guide rods 4 and is used for pressing the standard screen 1. After the standard sieve 1 containing the samples is placed on the base 2, an operator slides the pressing rod 6 and enables the lower surface of the pressing rod 6 to abut against the standard sieve 1, and then the operator can start the vibrating device 3 to intermittently knock the base 2, so that the samples on the standard sieve 1 can be screened along with the intermittent movement of the base 2. In order to facilitate the operator to move the pressing rod 6 up and down, a handle 7 is fixedly connected to the upper surface of the pressing rod 6.

Referring to fig. 1 and 2, a connecting pipe 8 with a circular cross section is slidably sleeved on the side wall of each guide rod 4, the inner side wall of the connecting pipe 8 is tightly attached to the side wall of each guide rod 4, and the upper end of the connecting pipe 8 is fixedly connected with the lower surface of the pressing rod 6. Four channels 9 have been seted up on the perisporium of connecting pipe 8, and the equal angle interval distribution of four channels 9 is on connecting pipe 8, and four channels 9 all communicate the interior outer wall of connecting pipe 8, and all slip in four channels 9 and inlay and be equipped with ball 10, and ball 10 has partial region to wear out the interior outer wall of connecting pipe 8 all the time. The threaded sleeve is equipped with one and rotates cover 11 on the lateral wall of connecting pipe 8, rotates on the inner wall of cover 11 circumference offer with the butt inclined plane 12 of ball 10 butt, butt inclined plane 12 to the distance between the 11 axis of rotation cover along keeping away from the direction crescent of clamping bar 6. After compressing tightly pole 6 supports tightly on standard sieve 1, the rotatory cover 11 that rotates of operator, it will move towards the direction of keeping away from compressing tightly pole 6 to rotate cover 11 under the effect of screw thread, interval between butt inclined plane 12 and the ball 10 diminishes gradually, ball 10 will press from both sides tight guide bar 4 under the effect of butt inclined plane 12 eventually, and then support tight location to compressing tightly pole 6, make compressing tightly pole 6 compress tightly on standard sieve 1 always, so a plurality of standard sieves 1 not only inseparable with the butt, still firmly support tightly on base 2 simultaneously, greatly reduced divide the produced noise of sieve in-process. If the position of the pressing rod 6 is to be readjusted, the operator rotates the rotating sleeve 11 in the reverse direction so that the balls 10 no longer clamp the guide rod 4. In order to facilitate the operator to rotate the rotating sleeve 11, three force application parts 13 are fixedly connected to the outer side wall of the rotating sleeve 11, and the three force application parts 13 are distributed on the rotating sleeve 11 at equal angular intervals. The rotating sleeve 11 and the abutting inclined surface 12 form a driving assembly; the channel 9, the ball 10 and the drive assembly constitute a locking mechanism.

Referring to fig. 2, four grooves 14 having arc-shaped cross sections are formed in the side wall of the guide bar 4 corresponding to the four balls 10, and the length direction of the grooves 14 is the same as the length direction of the guide bar 4. The part of the ball 10 penetrating out of the inner wall of the connecting pipe 8 is embedded in the groove 14 in a sliding manner, and the radius of the groove 14 is the same as that of the ball 10. When the contact inclined plane 12 makes the ball 10 clamp the guide rod 4, the ball 10 will be attached to the groove 14, the original point contact of the ball 10 and the guide rod 4 is changed into the existing line contact, the contact area between the guide rod 4 and the connecting pipe 8 is increased, and the stability of the locked compression rod 6 is improved.

Referring to fig. 1, the lower surface fixedly connected with one deck rubber pad 15 of compression bar 6, rubber pad 15 one can increase the frictional force between compression bar 6 and the standard sieve 1, reduces the probability that standard sieve 1 takes place the level and rocks, reduces and divides the produced noise of sieve in-process, and two still can absorb the buffering to the vibration of vertical side, play the effect of noise reduction equally.

The lower surface of connecting rod 5 is fixedly connected with three cross section and is the annular magnet 16 of circle, and the position of three magnet 16 and the position one-to-one of three guide bar 4, and the last fixed surface of clamping bar 6 is connected with three cross section and is the annular metal block 17 of circle equally, and the position one-to-one of three metal block 17 and the position of three magnet 16, and metal block 17 can carry out magnetism with the magnet 16 that corresponds and inhale the cooperation. When the operator is ready to put in or take out the standard sieve 1, the operator slides the pressing bar 6 and causes the metal block 17 on the pressing bar 6 to be attracted to the magnet 16, so that the pressing bar 6 can be quickly positioned at the upper end of the guide bar 4, facilitating the operator to put in or take out the standard sieve 1.

The implementation principle of the embodiment is as follows: after the standard sieve 1 containing the sample is placed on the base 2, an operator slides the pressing rod 6 and enables the lower surface of the pressing rod 6 to abut against the standard sieve 1, after the pressing rod 6 abuts against the standard sieve 1, the operator rotates the rotating sleeve 11, the rotating sleeve 11 moves towards the direction away from the pressing rod 6 under the action of threads, the distance between the abutting inclined surface 12 and the ball 10 gradually decreases, the ball 10 finally clamps the guide rod 4 under the action of the abutting inclined surface 12, and then the pressing rod 6 is abutted and positioned, so that the pressing rod 6 can be always pressed against the standard sieve 1, therefore, the plurality of standard sieves 1 not only tightly abut against each other, but also firmly abut against the base 2, if the position of the pressing rod 6 is to be adjusted again, the operator reversely rotates the rotating sleeve 11, and the ball 10 does not clamp the guide rod 4 any more. Finally, the operator can start the vibration device 3 to intermittently knock the base 2, so that the samples on the standard sieve 1 can be sieved along with the intermittent movement of the base 2.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
