Description

Technical Field

[0001] The utility model relates to the technical field of screening, and more specifically to a screening device for grading medicinal powder. Background Art

[0002] After the medicinal materials are ground, they need to be screened with screening equipment to obtain medicinal powder of suitable particle size. However, after long-term use of the existing screening equipment, the medicinal powder residues inside the equipment will continue to accumulate on the screen and dry, thereby affecting the screening efficiency of the screen. Therefore, the screen needs to be taken out and cleaned from time to time. For example, the patent with publication number CN210098214U discloses a medicinal powder screening device, including a device body, and two screening mechanisms are arranged inside the device body. The device body includes an outer shell and a device main cover, and four second threaded holes are opened on the top of the outer shell. The screening mechanism includes an "H"-shaped slider, a connecting rod and a screen, and the connecting rod is tightly welded to one side of the "H"-shaped slider, and two third threaded holes are opened on the top of one side of the "H"-shaped slider, and the second bolt is threadedly connected to the inner thread of the third threaded hole. A screen groove is opened on the right side of the "H"-shaped slider, and two sink grooves are opened on the surface of the screen groove. Fixed rings are installed at the four corners of the screen.

[0003] The above patent fixes the screen inside the device by setting a second bolt, a third threaded hole, a sink and a fixing ring structure, and the entire screen can be disassembled and cleaned by unscrewing the second bolt. However, in actual use, the above patent still needs to rotate multiple second bolts multiple times, and disassembly and installation is still relatively troublesome.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a screening device for powder grading is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a screening device for grading medicinal powder to solve the problems existing in the above-mentioned background technology.

[0006] The utility model provides the following technical scheme: a screening device for grading medicinal powder, comprising a screening box, a base, and a vibration motor, wherein an opening is provided on one side of the screening box, a screening plate is slidably mounted on the inner wall of the opening of the screening box, a discharging port corresponding to the screening plate is provided on the side wall of the screening box, a baffle is movably fitted in the opening of the screening box, a connecting block is fixedly mounted on one side of the baffle, two connecting blocks are fixedly mounted on one side of the screening box, a locking rod is slidably penetrated and mounted on the outer sides of the two connecting blocks, a limiting block is fixedly mounted on one end of the locking rod, a spring is fixedly connected between the limiting block and the two connecting blocks, the other end of the locking rod slides through a connecting block, a handle is provided between the two connecting blocks and the first connecting block, the handle is fixedly mounted on the outer side of the locking rod, and the distance between the handle and the second connecting blocks is greater than the length of the locking rod inserted into the first connecting block.

[0007] Furthermore, the number of the screening plates is set to two, the two screening plates are symmetrically and tiltedly distributed, and the upper sieve holes are larger than the lower sieve holes. By setting the number of the screening plates to two, multi-stage screening of the material is achieved, thereby obtaining materials with different particle sizes.

[0008] Furthermore, two handles are fixedly installed on one side of the baffle, and the two handles facilitate the staff to pull the baffle.

[0009] Furthermore, a T-shaped block is fixedly installed on one side of the screening plate, and a sliding groove corresponding to the T-shaped block is opened on the side wall of the baffle. By inserting the T-shaped block into the inside of the baffle, the stability of the connection of the baffle on the device is improved, and it is convenient for the staff to pull the screening plate out of the device.

[0010] Furthermore, a rubber ring is provided between the locking rod and the fitting surface of a connecting block, and the rubber ring is fixedly mounted on the inner wall of a through hole of a connecting block. The rubber ring makes the locking rod inserted into the connecting block more stable, so as to reduce the influence of the shaking of the device on the locking rod.

[0011] Furthermore, the cross section of the locking rod is set to be a rectangle. By setting the cross section of the locking rod to be a rectangle, it is prevented that a connecting block inserted by the locking rod can rotate along the locking rod as the axis, thereby affecting the fixation of the baffle.
