[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, a vibrating screen structure for lotus root starch production includes a base 1. The top and rear ends of the base 1 are open. Four support arms 2 are symmetrically installed at the four corners of the top of the base 1. The top ends of the four support arms 2 are fixedly connected to an upper frame 3. A screening component 4 is provided between the base 1 and the upper frame 3. A feeding component 6 is provided at one end of the base 1 and the upper frame 3 along their length direction. A material holding component 5 is provided in the inner cavity of the base 1.

[0028] In this solution, lotus root starch is poured onto the screening component 4 at the bottom of the upper frame 3. By setting the screening component 4 to vibrate and screen the lotus root starch, it is possible to efficiently separate lotus root starch particles of different sizes. During the vibration, smaller lotus root starch particles can quickly pass through the screen, while larger particles or clumps of lotus root starch remain on the screen. The feeding component 6 is set to repeatedly convey the clumps of lotus root starch to the screening component 4. The upward conveyed lotus root starch material falls freely onto the screening component 4 after passing the uppermost part of the feeding component 6. This repeated vibration of the clumps of lotus root starch effectively breaks down and refines the clumps, improving the screening quality and uniformity of the lotus root starch.

[0029] Specifically, such as Figures 2-4 As shown, the screening component 4 includes a fixed frame 41, a fixed bracket 42, two connecting blocks 44 and three fixed sleeves 45. The filter plate 411 is fixedly installed in the inner cavity of the fixed frame 41 by a snap fastener. The middle of the rear end of the fixed frame 41 is hinged to the middle of the rear side of the bottom end of the upper frame 3.

[0030] The filter plate 411 is installed in the fixed frame 41 by a snap fastener, so that the filter plate 411 with different pore sizes can be replaced according to the required particle screening.

[0031] Further, the front end of the fixed frame 41 is equidistantly fixedly provided with three connecting plates 48, three fixed sleeves 45 are equidistantly fixedly arranged on the bottom end of the upper frame 3, and the three fixed sleeves 45 and the three connecting plates 48 are respectively arranged in a vertical relationship, and three springs 49 are respectively arranged between the opposite surfaces of the three fixed sleeves 45 and the three connecting plates 48.

[0032] The two connecting blocks 44 are symmetrically arranged on the lower side of the vertical front end of the two support arms 2 on the most front side, the two connecting blocks 44 are penetrated by a rotating shaft 46 in a rotating connection mode, the outer surface of the rotating shaft 46 is equidistantly fixedly provided with three cams 47, and the outer surfaces of the three cams 47 are respectively in contact with the bottom end of the three connecting plates 48.

[0033] The fixed frame 42 is fixedly arranged on the left corner of the front side of the base 1, the top end of the fixed frame 42 is fixedly provided with a motor 43, and the output shaft of the motor 43 is fixedly connected with the rotating shaft 46 through a shaft coupling.

[0034] The motor 43 is started, the output shaft of the motor 43 drives the three cams 47 to rotate eccentrically through the rotating shaft 46, so that the three cams 47 push the three cams 47 at the front end of the fixed frame 41 when the three cams 47 rotate eccentrically, so that the fixed frame 41 reciprocates up and down, and when the fixed frame 41 reciprocates up and down, the lotus root powder on the filter plate 411 in the inner cavity of the fixed frame 41 can fall downward through the filter holes of the filter plate 411 in the vibration process.

[0035] The agglomerated lotus root powder cannot pass through the filter holes, so the agglomerated lotus root powder passes through the opening on the front side of the filter plate 411 and falls downward into the feeding assembly 6 to reciprocate and knock.

[0036] Further, the feeding assembly 5 comprises a storage tank 51 and an adapter tank 52, the storage tank 51 is slidingly arranged on the bottom end of the inner cavity of the base 1, the adapter tank 52 is fixedly arranged on the upper side of the front end of the inner cavity of the base 1, the top end and the right end of the adapter tank 52 are open, the inner cavity of the adapter tank 52 is provided with a slope, and the slope bottom of the adapter tank 52 is arranged on one side close to the opening end.

[0037] The agglomerated lotus root powder falls into the adapter tank 52 through the opening on the top end of the front side of the filter plate 411, and rolls along the slope of the inner cavity of the adapter tank 52 to the 8, and the lotus root powder filtered by the filter plate 411 falls into the storage tank 51 for centralized treatment.

[0038] It should be particularly pointed out that the specific installation mode of the motor 43 and the connection mode and control method of the circuit used in the utility model both belong to conventional design, and the utility model will not be described in detail.

[0039] Example two

[0040] The embodiment is based on the embodiment one, and the lumps of lotus root powder are conveyed upward again through the adapter box 52, and then fall on the screening assembly 4 to be screened again. The falling generates the falling force, and the vibration effect generated by the screening assembly 4 repeatedly knocks and vibrates the lumps of lotus root powder, so that the lumps of lotus root powder can be effectively further broken and refined, and the screening quality and uniformity of the lotus root powder are improved.

[0041] Specifically, as shown in the drawings, Figures 5-6 The feeding assembly 6 includes a feeding seat 61 and a transmission rod 64. The feeding seat 61 is fixedly installed at the right end of the base 1. The feeding seat 61 is in a slope shape with the front low and the back high. The side of the feeding seat 61 close to the opening end of the adapter box 52 is in an open shape in the length direction of the inner cavity of the feeding seat 61. The side of the feeding seat 61 close to the upper frame 3 is extended to the upper part of the upper frame 3 in the height direction.

[0042] A plurality of rotating rollers 62 are rotatably installed at the two ends of the feeding seat 61 in the length direction of the inner cavity of the feeding seat 61. A conveying belt 63 is rotatably connected to the outer surfaces of the two rotating rollers 62. The transmission rod 64 is fixedly connected to the right end of the rotating shaft 46. The right end of the rotating shaft 46 is fixedly connected to the two single-groove pulleys 65 at the highest rotating roller 62. The right end of the rotating shaft 46 is fixedly connected to the double-groove pulley 66 at the lowest rotating roller 62. The double-groove pulley 66 is in transmission connection with the two single-groove pulleys 65 through the two transmission belts 67.

[0043] When the lumps of lotus root powder fall on the conveying belt 63 rotatably arranged in the feeding seat 61 through the adapter box 52, the transmission rod 64 is driven to rotate by the rotating shaft 46. The transmission rod 64 is rotatably connected to the two single-groove pulleys 65 at the uppermost rotating roller 62. The double-groove pulley 66 is rotatably connected to the lowermost rotating roller 62. The double-groove pulley 66 is in transmission connection with the two single-groove pulleys 65 through the two transmission belts 67. In this way, the transmission rod 64 drives the plurality of rotating rollers 62 to rotate when the transmission rod 64 rotates, so that the lumps of lotus root powder on the conveying belt 63 are conveyed upward. The lumps of lotus root powder are conveyed to the lumps of lotus root powder at the uppermost position, and then fall downward on the filter plate 411. In this way, the lumps of lotus root powder are repeatedly knocked and vibrated, so that the lumps of lotus root powder can be effectively further broken and refined.
