[0034] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0035] Embodiment 1

[0036] like Figure 1 to Figure 2 As shown, a vibrating screening machine for horizontal and vertical vibration includes a vibrating screening machine body 1, a guide assembly 2 mounted on the vibrating screening machine body 1, and a pressurizing assembly 4 slidably arranged on the guide assembly 2 via a pneumatic assembly 3;

[0037] After the screening drum 5 is placed on the vibration screening machine body 1, it is regularly vibrated in horizontal and vertical directions.

[0038] In this embodiment, by setting the pressurizing component 4, the vibration screening machine body 1 can complete both horizontal vibration and vertical vibration. After the sample is vibrated and screened within the specified time, the required target sample can be successfully obtained, thereby improving work efficiency.

[0039] Further, if Figure 3 As shown, the guide assembly 2 includes a plurality of guide rods 21 arranged along the circumferential direction of the vibration screening machine body 1 and a mounting seat 22 installed on the upper end of the guide rods 21, wherein an opening 23 is formed between two of the guide rods 21, and the screening drum 5 is placed in the vibration screening machine body 1 through the opening 23.

[0040] In this embodiment, by providing the guide rod 21, the pressure assembly 4 carries the screening drum 5 to move up and down in the vertical direction, thereby playing a guiding and supporting role.

[0041] Further, if Figure 3 As shown, the pneumatic assembly 3 includes a cylinder member 31 mounted on the mounting seat 22 and a connecting rod 32 arranged at the output end of the cylinder member 31.

[0042] In this embodiment, the pneumatic component 3 drives the pressurizing component 4 to complete the lifting work.

[0043] Further, if Figures 5 and 6 As shown, the pressurizing component 4 includes:

[0044] A connecting plate 41, the connecting plate 41 is fixedly connected to the lower end of the connecting rod 32 and is a hollow structure. The connecting plate 41 is slidably arranged on the guide rod 21 along the vertical direction through a sliding groove 42;

[0045] A supporting member 43, which is arranged in the connecting plate 41 and is used to control the clamping tightness of the guide rod 21;

[0046] A clamping member 44, which is arranged under the connecting plate 41 and is used to control the clamping tightness of the screening drum 5; and

[0047] The control member 45 is installed on the connecting plate 41 and is used to drive the supporting member 43 and the clamping member 44 to transmit synchronously.

[0048] In this embodiment, by providing a top support member 43 and a clamping member 44, the screening drum 5 is limited in the vertical direction when it is vibrating horizontally; conversely, when the screening drum 5 is vibrating vertically, the screening drum 5 is limited in the horizontal direction. The screening drum 5 is firmly fixed during vibration screening to avoid loosening during vibration, and secondly, sample leakage is avoided during horizontal and vertical vibrations.

[0049] Further, if Figure 5 As shown, the diameter of the sliding groove 42 is larger than the diameter of the guide rod 21 .

[0050] In this embodiment, the diameter of the sliding groove 42 is larger than the diameter of the guide rod 21, and when the top support member 43 releases the limiting work on the guide rod 21, it will not affect the lifting efficiency of the screening drum 5. At the same time, the guide rod 21 in the vertical direction must be clean and tidy to avoid foreign matter.

[0051] Further, if Figure 6 and Figure 7 As shown, the control member 45 includes a rotary valve 452 rotatably disposed on the connecting plate 41 through a cross ring 451 and a cam 453 fixedly connected to the rotary valve 452 and having a plum blossom structure.

[0052] Further, if Figure 6 As shown, the top support members 43 are arranged in several groups and are arranged one by one corresponding to the guide rods 21, which include a support 431 located above the cam 453, a telescopic unit 432 horizontally connected to the support 431, a connecting rod 433 arranged at the outer end of the telescopic unit 432, a gasket 434 connected to the outer end of the connecting rod 433 and made of rubber material, and a transmission block 435 installed on the telescopic unit 432.

[0053] In this embodiment, by setting the control member 45 to cooperate with the support member 43, the rotating valve 452 drives the cam 453 to rotate, and the rotating cam 453 acts on the transmission block 435. The transmission block 435 pulls the telescopic unit 432, which is clamped on the guide rod 21 through the action of the gasket 434, thereby completing the vertical limitation of the screening drum 5. On the contrary, the control member 45 is reversed, and the support member 43 loses the limitation on the guide rod 21, thereby completing the smooth up and down lifting of the pressurizing component 4.

[0054] Furthermore, the rotary valve 452 is driven by a servo motor.

[0055] In this embodiment, the rotary valve 452 is driven by a servo motor, and the transmission is precise and accurate. After rotating into place, the cam 453 is supported and positioned by self-locking.

[0056] Further, if Figure 6 As shown, the clamping member 44 includes a clamping block 441 slidably disposed on the connecting plate 41 and connected to the second connecting rod 433 . The contact portion of the clamping block 441 with the screening drum 5 is an electromagnet and is intermittently magnetically attracted to the screening drum 5 .

[0057] In this embodiment, by providing a top support member 43 in conjunction with the clamping member 44, the screening drum 5 is firmly positioned by utilizing magnetic attraction combined with the mechanical clamping of the clamping block 441, thereby improving the safety factor and preventing the material from falling into the screening drum 5 due to loose clamping when vibrating in the vertical direction. On the other hand, the same power is utilized to accomplish the simultaneous execution of the two actions, thereby saving additional power output and reducing production costs.

[0058] It should be noted that the electromagnet on the clamping block 441 can be started and stopped by an electrical signal. When vibrating vertically, the electromagnet is turned on to complete the attraction; conversely, when vibrating horizontally, the electromagnet is turned off, which does not affect the horizontal vibration amplitude limit of the screening drum 5.

[0059] Embodiment 2

[0060] like Figure 6 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0061] Furthermore, the telescopic unit 432 is a compression spring structure.

[0062] In this embodiment, the telescopic unit 432 is a compression spring structure, so that when not subjected to external force, the clamping block 441 relies on the magnetic force and the clamping force of the compression spring to complete the clamping work of the screening drum 5, thereby preventing the screening drum 5 from falling when vibrating up and down.

[0063] Working process:

[0064] After the screening drum 5 is placed on the vibration screening machine body 1, it needs to be fixed when vibrating in the horizontal direction, and a lifting function needs to be added in the vertical direction so that it can vibrate up and down. After horizontal screening, which takes 10 seconds, vertical screening is performed again, which takes 10 seconds. These operations are performed alternately in sequence to improve the vibration screening effect and obtain the required screening samples in a short time.

[0065] In the description of the present invention, it should be understood that the terms "front and back", "left and right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the equipment or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0066] Of course, in the present technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0067] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
