Description

Technical Field

[0001] The utility model relates to the technical field of oilseed screening equipment, in particular to a perilla oil raw material screening machine. Background Art

[0002] Perilla seeds, as the raw material of perilla oil, are the seeds of a plant of the Labiatae family, Perilla. It can be used as a seasoning, which has the effects of removing fishy smell, enhancing freshness and flavor. At the same time, it has certain medicinal value, and has the effects of lowering gas, clearing phlegm, moistening the lungs and widening the intestines. Perilla is also a highly efficient plant "preservative". Perilla seeds contain a large amount of oil, with an oil yield of about 45%. The oil contains 62.73% linolenic acid, 15.43% linoleic acid, and 12.01% oleic acid. The protein content in oil seeds accounts for 25%, and it contains 18 kinds of amino acids, among which the content of lysine and methionine is higher than that of high-protein plant grain amaranth. In addition, there are oryzanol, vitamin E, vitamin B1, nitric acid, phospholipids, etc.; after mechanical harvesting, perilla seeds are mixed with impurities such as diatoms, leaves, and soil, which need to be removed. The existing removal methods are mostly through manual screening or screening machines with vibrating screens to screen perilla seeds, stems, leaves, and soil.

[0003] Existing screening machines usually have multiple layers of screens inside the box, and the perilla seeds of different sizes are screened by the size of the apertures on the screens. The apertures on the screens generally decrease from top to bottom, so that large-grained perilla seeds remain in the upper layer, small-grained perilla seeds remain in the lower layer, and the soil is screened out of the screen box through the bottom layer of the screen; however, this method of screening the soil will cause soil to remain on each layer of the screen, which may easily cause unclean screening of the soil; at the same time, the top layer of the screen may have stems and leaves left on it, which may easily clog some of the meshes of the screen, causing some perilla seeds to be unable to fall to the next layer, resulting in waste of perilla seeds and stems and leaves mixed together.

[0023] like Figure 1-3 As shown, the first sieve disc group 7 includes a guide disc 71 which is inclined downward from the inside to the outside with the rotating shaft 3 as the center, and the guide disc 71 is provided with a coarse screening area 72, a soil removal area 73 and a material discharge area 74 in sequence along its radial outward direction. The coarse screening area 72 corresponds to the feed port 6, and a plurality of convex rods 75 are arranged above it; the top surface of the convex rods 75 distributed on the guide disc 71 gradually becomes shorter from the rotating shaft 3 to the outside to form a concave structure. When the material enters the coarse screening area 72 through the feed port 6, the larger stems and leaves in the material will be blocked by the convex rods 75 to achieve separation from the perilla seeds; all the convex rods 75 form a concave structure, which can limit the stems and leaves, and prevent the stems and leaves from sliding onto the surface of the guide disc 71 and the soil removal area 73 during rotation.

[0024] like Figure 3 As shown, the soil removal area 73 is distributed with a plurality of filter holes 76, and a screen is arranged in the filter holes 76; the filter holes 76 are distributed in a ring shape on the surface of the guide plate 71, and a baffle 79 with an arc-shaped top is arranged on the side of the filter hole 76 away from the rotating shaft 3, and the baffle 79 can delay the sliding of the material on the surface of the guide plate 71, so that the soil has sufficient time to contact the filter holes 76, ensuring that the soil can smoothly slide from the filter holes 76 into the dust collecting box 78.

[0025] The unloading area 74 is located at the edge of the guide plate 71, and a unloading port 77 connected to the adjacent fine screening plate 8 is arranged above it. Finally, the perilla seeds that have passed through the coarse screening area 72 and the soil removal area 73 will enter the fine screening plate 8 through the unloading port 77 after being separated from the stems, leaves and soil, and the perilla seeds will be classified according to their size by the multiple fine screening plates 8 on the lower layer.

[0026] like Figure 2 , 4As shown, each of the fine screen discs 8 and the first screen disc group 7 is respectively provided with a first mounting ring 32 and a second mounting ring 33 which are sleeved with the rotating shaft 3; the first mounting ring 32 and the second mounting ring 33 are provided with a clamping block 34 which is clamped with the clamping groove 31; the fine screen disc 8 can be connected to the rotating shaft 3 through the first mounting ring 32, and the guide disc 71 and the dust box 78 in the first screen disc group 7 can be connected to the second mounting ring 33. When installing, the staff can first open the cover plate 5, and then insert the multiple fine screen discs 8 equipped with the first mounting block into the rotating shaft 3 in turn, and finally install the second mounting ring 33 equipped with the guide disc 71 and the dust box 78 on the rotating shaft 3, and finally complete the installation of the sieve disc. The above connection structure makes disassembly and assembly very convenient and is convenient for the staff to operate.

[0028] like Figure 4 As shown, the inner wall of the screening chamber 2 is provided with a fixing strip 9 corresponding to the fine screening disc 8, the fixing strip 9 is located above the fine screening disc 8 and is provided with a mounting frame 10, and the mounting frame 10 is provided with a brush 11 that fits with the inner wall of the fine screening disc 8; the fixing strip 9 is located on the inner wall of the screening chamber 2, and its inner diameter is larger than the outer diameter of the fine screening disc 8, and a mounting frame 10 is provided above each fine screening disc 8, and the brush 11 on the mounting frame 10 can sort the perilla seeds in the fine screening disc 8 to prevent the perilla seeds from being stuck in the holes of the fine screening disc 8, so that the perilla seeds can move evenly on the surface of the fine screening disc 8 to ensure sufficient screening.

[0029] like Figure 3 As shown, the inner wall of the screening chamber 2 is provided with a fixed block 12 located above the guide plate 71, and a connecting rod 13 is clamped on the fixed block 12. The connecting rod 13 is provided with a cleaning brush 14 located on the rotation path of the filter hole 76. The cleaning brush 14 can scrape the filter hole 76, so as to clean the soil on the surface of the perilla seeds and break up the lumps of soil to ensure that the soil can smoothly pass through the filter hole 76; at the same time, the perilla seeds blocked by the blocking bar 79 can be moved, so that the perilla seeds can smoothly pass through the soil removal area 73 to reach the unloading area 74.

[0030] like Figure 2As shown, the guide plate 71 and the fine screen plate 8 and the adjacent fine screen plates 8 are abutted with an isolation block 15 sleeved on the rotating shaft 3. The isolation block 15 can allow a gap between adjacent fine screen plates 8 and a gap between the first screen plate group 7 and the fine screen plate 8, thereby ensuring the normal operation between the screen plates.
