DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0032] Embodiment 1:

[0033] A grading screening and packaging device, in order to improve the screening efficiency, such as Figures 1 to 4 As shown, it includes a base 1 and a screening part, and the screening part includes:

[0034] The stand 24 is fixed to the top outer wall of the base 1 by bolts, and the outer wall of one side of the stand 24 is rotatably connected to a driving rod 2 19, and a screen box assembly 1 is fixed between the two driving rods 2 19;

[0035] The second driving plate 12 is welded to the outer wall of the second driving rod 19, and one end of the second driving plate 12 away from the second driving rod 19 is rotatably connected to the third driving plate 13 via a rotating shaft;

[0036] Driving plate four 25: it is rotatably connected to one end of driving plate three 13 via a rotating shaft;

[0037] Driving plate 10: It is fixed to the inner wall of one side of the stand 24 by bolts, and the through hole opened in the side wall of the driving plate 10 is rotatably connected with a driving rod 14, and the driving rod 14 and the driving plate 4 25 are welded and fixed, and a screen box assembly 2 is fixed between the two driving rods 14;

[0038] Driving motor 11: It is fixed to the outer wall of one side of the stand 24 by bolts, and the output end of the driving motor 11 is connected to one end of the driving rod 2 19 through a coupling;

[0039] When the chrysanthemums need to be screened, the chrysanthemums can be screened once using the screen box component 1. After screening, the chrysanthemums pass through the screen box component 1 and fall into the screen box component 2 for secondary screening, thereby realizing multi-level screening of the chrysanthemums;

[0040] During the screening process, the driving motor 11 is used to drive the driving rod 2 19 to make a certain amplitude of left and right swinging motion. At the same time, the parallelogram structure formed by the driving plate 10, the driving plate 2 12, the driving plate 3 13 and the driving plate 4 25 is used so that when the screen box component 2 swings left and right, the screen box component 1 can also swing left and right at the same time. The purpose of this is to make the chrysanthemums more evenly distributed in the screen box component 1 and the screen box component 2 during the screening process, so as to avoid excessive accumulation of chrysanthemums in a certain area, which affects the screening efficiency.

[0041] Furthermore, the screen box assembly 2 includes a sub-screen plate 2 4, a screen mesh 15 and a sliding plate 16, the sub-screen plate 2 4 is fixed between two driving rods 14 by welding, the screen mesh 15 is welded to the bottom of the sub-screen plate 2 4, and the sliding plate 16 is slidably connected to the inner wall of the jack opened at the top of the sub-screen plate 2 4;

[0042] The screen box assembly 1 includes a sub-screen plate 13, a screen mesh 17 and a sliding plate 18. The sub-screen plate 13 is fixed between two driving rods 19 by welding. The screen mesh 17 is welded to the bottom of the sub-screen plate 13, and the sliding plate 18 is slidably connected to the inner wall of the jack opened at the top of the sub-screen plate 3.

[0043] During screening, the chrysanthemums are introduced into the sub-screening plate 2 4, and the chrysanthemums are preliminarily screened by using the screen 15. The chrysanthemums larger than the aperture of the screen 15 are retained by the screen 15, and the chrysanthemums smaller than the aperture of the screen 15 pass through the sieve holes of the screen 15 and fall into the sub-screening plate 3 for secondary screening. When the screening is completed, the sub-screening plate 13 and the sub-screening plate 2 4 are tilted by the driving motor 11. When it is necessary to guide the chrysanthemums retained in the sub-screening plate 13 and the sub-screening plate 2 4, the sliding plate 16 is slid along the sub-screening plate 2 4, and the sliding plate 2 18 is slid along the sub-screening plate 3, so that the chrysanthemums in the sub-screening plate 2 4 and the chrysanthemums in the sub-screening plate 3 slide along the screen 15 and the screen 2 17 respectively, so as to facilitate the sub-packaging and collection of the chrysanthemums.

[0044] The outer diameter of the sub-screening plate 2 4 is smaller than that of the sub-screening plate 1 3 , so that during the screening process, part of the chrysanthemums can be prevented from falling outside the sub-screening plate 1 3 when they fall into the sub-screening plate 1 3 .

[0045] Furthermore, a collection frame 2 is placed on the top of the base 1;

[0046] The chrysanthemums passing through the sieve holes 17 of the sieve 2 can be collected by the collecting frame 2.

[0047] Working principle: When chrysanthemums need to be screened, firstly, the chrysanthemums are introduced into the sub-screening plate 2 4, and the chrysanthemums are preliminarily screened by the screen 15. The chrysanthemums with a mesh smaller than the mesh of the screen 15 fall into the sub-screening plate 1 3 and are screened by the screen 2 17 for secondary screening. The chrysanthemums with a mesh smaller than the mesh of the screen 17 fall into the collection frame 2 for collection, thereby realizing multi-level screening of chrysanthemums.

[0048] During the screening process, the driving motor 11 is used to drive the driving rod 2 19 and the sub-screening plate 1 3 to swing left and right. The parallelogram structure formed by the driving plate 1 10, the driving plate 2 12, the driving plate 3 13 and the driving plate 4 25 is used. When the sub-screening plate 1 3 swings left and right, the sub-screening plate 2 4 swings left and right at the same time, so that the chrysanthemums are more evenly distributed on the screen 1 15 and the screen 2 17 during screening;

[0049] After the screening is completed, the driving motor 11 is used to drive the sub-screen plate 1 3 and the sub-screen plate 2 4 to tilt. When the chrysanthemums trapped in the sub-screen plate 1 3 and the sub-screen plate 2 4 need to be exported, the sliding plate 1 16 is slid along the sub-screen plate 2 4, and the sliding plate 2 18 is slid along the sub-screen plate 1 3, so that the chrysanthemums in the sub-screen plate 2 4 and the chrysanthemums in the sub-screen plate 1 3 slide along the screen 1 15 and the screen 2 17 respectively, thereby facilitating the collection of the chrysanthemums.

[0050] Embodiment 2:

[0051] A grading, screening and packaging device, such as Figures 1 to 4 As shown, in order to facilitate the feeding of chrysanthemums, this embodiment makes the following supplements on the basis of embodiment 1: a bracket 6 is welded on the top of the stand 24, and a material box 5 is embedded in the through hole opened on the top of the bracket 6, and an annular shell 8 is welded on the bottom of the material box 5, and a guide pipe 21 is welded on the bottom of the annular shell 8;

[0052] The material box 5 can be provided to store the chrysanthemums that need to be screened, and the annular shell 8 and the outlet pipe 21 can be used to guide the chrysanthemums out for loading.

[0053] Furthermore, a rotating column 9 is rotatably connected to the inner wall of one side of the bracket 6, and a swing column 23 is welded to one end of the rotating column 9, and the outer circumferential wall of the swing column 23 and the inner circumferential wall of the annular shell 8 are rotatably connected, and a through hole 20 adapted to the inner diameter of the outlet pipe 21 is opened inside the swing column 23;

[0054] The outer wall of the rotating column 9 and the outer wall of the second driving rod 19 are both fixed with pulleys 22 through pins, and the two pulleys 22 are driven by a belt 7;

[0055] By utilizing the transmission effect of the wheel belt 7, the swing column 23 and the through hole 20 can swing left and right following the driving rod 2 19. When the through hole 20 and the outlet pipe 21 overlap, the chrysanthemums are fed through the through hole 20 and the outlet pipe 21. When the through hole 20 and the outlet pipe 21 are misaligned, the bottom of the material box 5 is blocked by the swing column 23, so that the chrysanthemums are no longer fed. In this way, when the sub-screening plate 1 3 and the sub-screening plate 2 4 are tilted and the screened chrysanthemums are unloaded, the feeding function can be stopped. This structure prevents the chrysanthemums from being fed too quickly in a short time, resulting in a large amount of chrysanthemums piling up on the screen 15, causing the chrysanthemums to overflow from the sub-screening plate 2 4.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
