[0005] The purpose of the present utility model can be achieved by the following technical solutions: A shock-type vibrating sieve machine includes a bottom frame. A vibrating table is connected to the bottom frame through a plurality of support springs. Vibration motors are installed on both sides of the vibrating table. At least three vertical rods are also installed on the vibrating table. A work semi-ring with adjustable position is slidably sleeved on the vertical rods. A T-shaped pressing rod is installed on the work semi-ring. The middle of the T-shaped pressing rod is connected with a handle. The ends of the T-shaped pressing rod are horizontally and slidably connected with movable shafts. The outer ends of the movable shafts are connected with locking pads, and the locking pads can abut against the side parts of the vertical rods. A return spring is provided between the inner ends of the movable shafts and the T-shaped pressing rod. The inner ends of the movable shafts are also connected with one end of a steel wire rope. The other end of the steel wire rope is connected with a control cross bar. The control cross bar is also vertically slidably connected to the handle. The T-shaped pressing rod is provided with three guide sleeves one and three guide sleeves two. The guide sleeves one are arranged close to the handle, and the guide sleeves two are arranged close to the movable shafts. The T-shaped pressing rod is also provided with a plurality of rubber pads.

[0006] A reinforcing semi-ring is also connected to the vertical rod through a nut, and the reinforcing semi-ring is located above the work semi-ring.

[0007] The vertical rod is also provided with an anti-slip serrated part that cooperates with the locking pad.

[0008] Four support legs are also installed on the bottom frame.

[0009] Compared with the prior art, the present shock-type vibrating sieve machine has the following advantages:

[0010] In the present utility model, multiple sieve trays are stacked on a vibrating table, and a lid is placed on the topmost sieve tray. The lid is pressed down by a T-shaped pressing rod to fix all the sieve trays on the vibrating table. Since the cross bar can be adjusted to drive the wire rope to act, the wire rope can pull the locking pad to act, and under the action of the return spring, it is convenient to make the T-shaped pressing rod in the unlocked state or the locked state, and the operation is convenient.

Detailed Description of the Preferred Embodiments

[0014] The following are specific embodiments of the present utility model in combination with the accompanying drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0015] Such as Figure 1 - Figure 2As shown in the figure, the present shock-type vibrating sieve machine includes a bottom frame 2. A vibrating table 4 is connected to the bottom frame 2 through a plurality of support springs 3. Vibration motors 5 are installed on both sides of the vibrating table 4. At least three vertical rods 14 are also installed on the vibrating table 4. In this embodiment, the number of vertical plates is three. A work semi-ring 9 with adjustable position is slidably sleeved on the vertical rod 14. A T-shaped pressing rod 10 is installed on the work semi-ring 9. A handle 11 is connected to the middle of the T-shaped pressing rod 10. The outer ends of the T-shaped pressing rod 10 are horizontally and slidably connected with movable shafts 16. The outer ends of the movable shafts 16 are connected to locking pads 15, and the locking pads 15 can abut against the side of the vertical rod 14. A return spring 17 is provided between the inner ends of the movable shafts 16 and the T-shaped pressing rod 10. The inner ends of the movable shafts 16 are also connected to one end of a steel wire rope 19. The other end of the steel wire rope 19 is connected to a control cross bar 21. The control cross bar 21 is also vertically slidably connected to the handle 11. There are three guide sleeves one 20 and three guide sleeves two 18 on the T-shaped pressing rod 10. The guide sleeves one 20 are arranged close to the handle 11, and the guide sleeves two 18 are arranged close to the movable shafts 16. In this embodiment, the steel wire rope 19 can be guided and limited by the guide sleeves one 20 and the guide sleeves two 18. There are also a number of rubber pads 8 on the T-shaped pressing rod 10. With this structure, when it is necessary to adjust the work semi-ring 9, hold the handle 11 and grasp the control cross bar 21 at the same time, so that the steel wire rope 19 pulls the movable shaft 16, and then the locking pad 15 is separated from the vertical rod 14, so that the handle 11 can drive the T-shaped pressing rod 10 to move up and down. After adjusting to the required position, only need to release the handle 11 and the control cross bar 21. Under the action of the return spring 17, the locking pad 15 abuts against the vertical rod 14, and the position of the work semi-ring 9 can be locked.

[0016] A reinforcing semi-ring 12 is also connected to the vertical rod 14 through a nut 13, and the reinforcing semi-ring 12 is located above the work semi-ring 9. With this structure, the stability of the connection between the columns can be increased by using the reinforcing semi-ring 12.

[0017] The vertical rod 14 also has an anti-slip serrated part 14a that cooperates with the locking pad 15.

[0018] Four support legs 1 are also installed on the bottom frame 2.

[0019] In the present utility model, a plurality of sieve trays 6 are stacked on the vibrating table 4, and a lid 7 is covered on the uppermost sieve tray 6. The lid 7 is pressed downward by the T-shaped pressing rod 10 to fix all the sieve trays 6 on the vibrating table 4. Since the control cross bar 21 can drive the steel wire rope 19 to act, the steel wire rope 19 can pull the locking pad 15 to act, and under the action of the return spring 17, it is convenient to make the T-shaped pressing rod 10 in the unlocked state or the locked state, and the operation is convenient.
