DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1 to 3As shown, a screening machine for the production and processing of traditional Chinese medicine comprises a frame 1, with a vibrating screening box 2 mounted on top of the frame 1, elastically connected to the frame 1 via an elastic member 3. The elastic member 3 is a spring, with the top end of the spring connected to the vibrating screening box 2 and the bottom end connected to the frame 1. Specifically, connecting blocks are provided at the four corners of the bottom of the vibrating screening box 2, which are connected to the top of the spring. The vibrating screening box 2 is only elastically connected to the frame 1, which reduces the impact of the frame 1 during vibration.
[0021] The vibrating screening box 2 has a feed inlet 4 at its top near its first end and a downward-extending discharge outlet 5 at its bottom near its second end. A vibration motor 6 is installed on the side, and several layers of screens 7 with varying apertures are located inside. The feed inlet 4 is used to feed mixed materials, while the discharge outlet is used to discharge the screened materials. The vibration motor 6 drives the vibrating screening box 2 to vibrate, and the screens 7 are used to screen Chinese medicinal materials of varying sizes. Preferably, there are at least two layers of screens 7, both tilted downward to allow the Chinese medicinal materials to slowly move along the screens 7.
[0022] Among them, such as Figure 3 As shown, the apertures of the several layers of screens 7 gradually decrease from top to bottom, enabling layer-by-layer screening. The discharge port 5 includes several branch outlets 8, each corresponding to a screening channel formed by a different screen 7. Each screening channel only selects Chinese medicinal materials of a specific size. A gap exists between adjacent branch outlets 8 to minimize the remixing of Chinese medicinal materials of different sizes during discharge.
[0023] like Figure 1 and Figure 4 As shown, a detachable material receiving box 9 is provided on the frame 1. The material receiving box 9 is located below the discharge port 5, and a number of sub-material receiving boxes 10 are provided inside. The sub-material receiving boxes 10 correspond to each branch outlet 8, respectively, and receive the Chinese medicines of different sizes after screening. Specifically, a mounting plate 17 is provided below the material receiving box 9. The mounting plate 17 is fixedly provided on the frame 1, and a slide groove adapted to the material receiving box 9 is provided on the top surface so that the material receiving box 9 can slide. A pull-out handle 18 is provided at one end of the material receiving box 9 to facilitate the operator to pull the material receiving box 9. At the same time, L-shaped connecting plates 19 are provided on the top of both sides of the sub-material receiving box 10. The L-shaped connecting plates 19 are mounted on the top surface of the material receiving box 9 and extend to the outside of the material receiving box 9. The L-shaped connecting plates 19 have two functions, one is to facilitate the top of the sub-material receiving box 9, and the other is to provide the sub-material receiving box 10 with a handle to facilitate its lifting out of the material receiving box 9.
[0024] A feed hopper 11 is located above the feed port 4. It has a flared inlet at its top and an outlet at its bottom that extends into the interior of the discharge port 5. A dust hood 12 is located on one side of the feed hopper 11. This hood communicates with the interior of the feed hopper 11 and its bottom end is connected to a dust pump 14 via a dust pipe 13. The outlet of the dust pump 14 is connected to a dust box 15 mounted on the frame 1. This dust pump 14 removes dust from the Chinese medicine during the feeding process, reducing dust dispersion during screening.
[0025] The feed port 4 is circumferentially provided with side baffles 16 extending upwards to increase the side baffle range of the feed port 4 and reduce the probability of Chinese medicinal materials flying out of the gap between the feed port 4 and the hopper 11.
[0026] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
