Description

Technical Field

[0001] This utility model relates to the field of screening devices, and in particular to a vibrating medicinal herb screening machine. Background Technology

[0002] When processing medicinal materials, screening is often required. In addition to grouping materials of suitable size together, screening can also remove impurities from the materials, making subsequent processing easier. Existing screening machines have a simple structure, generally consisting of a screening box with a vibration motor installed at the bottom for vibration screening. Screening with this structure is highly efficient.

[0003] However, the aforementioned screening machine still has certain defects. Specifically, the screen plates inside the screening box are arranged at a certain angle. Only when the screened material remains on the screen plate can it roll down the slope to the discharge port of that screen plate, so that the material does not accumulate on the screen plate. However, the current situation is that the material that rolls to the discharge port too quickly is often not fully screened. After the existing screening device finishes screening, there are often a lot of non-sized material that has not been screened out in the same size pile. Therefore, the structure of the existing screening machine needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating medicinal herb screening machine to solve the problem that insufficient screening is caused by materials rolling too fast towards the discharge port during screening in existing screening machines.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A vibrating medicinal herb screening machine includes a vibrating support frame and a screening box. The bottom of the screening box is connected to the vibrating support frame via an elastic connection structure. A vibrating motor is provided in the middle of the bottom surface of the screening box. A medicinal herb screening screen is provided in the middle of the screening box. The medicinal herb screening screen is inclined. The medicinal herb screening screen includes, from top to bottom, a large-size medicinal herb screening screen, a medium-size medicinal herb screening screen, a small-size medicinal herb screening screen, and a residue screening screen. The key feature is that the top surface of the medicinal herb screening screen is uniformly covered with buffer ridges, and the cross-section of the buffer ridges is semi-circular.

[0007] In this solution, buffer strips are evenly laid on the top surface of the medicinal material screening mesh, which can effectively reduce the speed at which the material rolls toward the discharge port, thus achieving full screening of the material.

[0008] As a further preferred embodiment of this utility model, the inlet of the screening box and the outlet of the feeding device are connected by a rubber dust cover.

[0009] It can continuously screen incoming materials and prevent dust pollution from contaminating the workshop environment.

[0010] As a further preferred embodiment of this utility model, one side of the screening box is a flip-type box wall, the bottom of the flip-type box wall is rotatably connected to the bottom plate of the screening box by a hinge, and the two sides of the flip-type box wall are detachably connected to the front and rear walls of the screening box by bolts.

[0011] The flip-top design allows for easy opening of the screening box walls to inspect and replace the internal structure.

[0012] As a further preferred embodiment of this utility model, the inner sides of both the front and rear walls of the screening box are uniformly provided with screening mesh plate insertion slots.

[0013] It facilitates the replacement of the screening screen for medicinal materials.

[0014] As a further preferred embodiment of this invention, the exterior of the screening box is also covered with a sound-absorbing layer.

[0015] It can effectively reduce noise.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] 1. In this solution, buffer strips are evenly laid on the top surface of the medicinal material screening mesh, which can effectively reduce the speed at which the material rolls toward the discharge port, thus achieving full screening of the material.

[0018] 2. It can continuously screen incoming materials and prevent dust pollution from contaminating the workshop environment.

[0019] 3. The flip-top design allows for easy opening of the screening box walls to inspect and replace the internal structure.

[0020] 4. Facilitates the replacement of the medicinal herb screening screen.

[0021] 5. Low noise during screening. Attached Figure Description
