DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 3 The utility model provides a technical solution: an anti-clogging organic fertilizer screening and processing device, comprising a base 1, a first U-shaped frame 5 is provided at one end of the top of the base 1, and a second U-shaped frame 19 is provided at the other end, the second U-shaped frame 19 and the first U-shaped frame 5 are both opened downward, the bottom ends of the first U-shaped frame 5 are rotatably connected to the base 1, and the bottom of the second U-shaped frame 19 is installed on the top of the vibration device, and the height of the first U-shaped frame 5 is lower than the height of the second U-shaped frame 19.

[0029] A bearing seat 7 is installed at the middle position of the top of the second U-shaped frame 19 and the first U-shaped frame 5, and a rectangular support frame 2 is obliquely provided between the two bearing seats 7. A support shaft 26 rotatably connected to the bearing seat 7 is installed at the middle of both ends of the rectangular support frame 2. At this time, the rectangular support frame 2 can rotate freely around the support shaft 26, and a screen 25 is installed in the rectangular support frame 2;

[0030] The support shaft 26 located at the top of the rectangular support frame 2 is connected to the rotating motor 14 , and the rotating motor 14 is installed on a motor mounting platform 15 , and the bottom of the motor mounting platform 15 is connected to the top of the vibration device through a plurality of support legs 16 .

[0031] Specifically, when the utility model is in use, the rotating motor 14 drives the rectangular support frame 2 to switch back and forth between 0-180 degrees, such as Figure 2 As shown, the angle of the rectangular support frame 2 in the initial position is 0, and it is completely turned over after it is rotated 180°, that is, after using one side of the screen 25 for screening for a period of time, the screen 25 is rotated 180° and turned over, so that the entire screen is "turned over" to continue screening, and the first screening surface is located at the bottom, and the attachments located under the screen can be vibrated and dropped by relying on the vibration device, and this repeated process can avoid blockage of the screen.

[0032] Furthermore, the screen 25 is composed of multiple pieces and the mesh number of each screen 25 decreases from top to bottom, and each screen 25 is a screening area (position number in the figure);

[0033] The upper and lower top surfaces of the rectangular support frame 2 are both installed with strip-shaped sealing covers 8, and a feeding channel 10 is installed on one side of the strip-shaped sealing cover 8 that is away from each other and located at one end close to the rotating motor 14;

[0034] First brackets 12 are installed on both sides of the top of the second U-shaped frame 19, and a feed trough 11 is installed between the tops of the first brackets 12 at an angle upward. The bottom of the feed trough 11 is in a retracted shape and is located above the feed channel 10. In actual use, the fertilizer can be transported to the feed trough 11 by a hoist, and then the fertilizer slides along the feed trough 11 into the feed channel 10, allowing the fertilizer to fall onto the screen for screening.

[0035] like Figure 1 and Figure 2 As shown, both sides of the top of the feed trough 11 are connected to the first bracket 12 through the second bracket 13.

[0036] Further, such as Figure 3 As shown, a top sealing plate 24 is installed in the top of the rectangular support frame 2, and the top sealing plate 24 is located between the upper and lower feed channels 10; Figure 2 As shown, when the fertilizer falls from the feeding channel 10, the fertilizer is in contact with the feeding channel 10, preventing the fertilizer from passing through the screen and flowing out of the feeding channel 10 below;

[0037] like Figure 2 and Figure 3 As shown, a bottom discharge port 23 is provided at the bottom of the rectangular support frame 2, and a plurality of screens 25 are installed between the bottom discharge port 23 and the top sealing plate 24. After the fertilizer passes through the surface of each screen 25 in turn, the largest fertilizer particles remaining fall from the bottom discharge port 23.

[0038] like Figure 2As shown, a baffle 22 is provided at the bottom of each screening area, that is, the baffle 22 is distributed at the connection of the screen 25, the edges of the baffle 22 are connected to the inner wall of the strip sealing cover 8, and a certain distance is provided between the baffle 22 and the rectangular support frame 2 to prevent the baffle 22 from blocking the flow of fertilizer;

[0039] A plurality of discharge channels 9 are installed on the sides of the two strip-shaped sealing covers 8 that are away from each other. The discharge channels 9 are respectively distributed at the bottom position of the screening area and at the corresponding positions of the bottom discharge port 23 .

[0040] Because each screen 25 corresponds to a screening area, the fertilizer needs to be screened multiple times, and the fine materials obtained after each screening are discharged to the outside from the corresponding discharge channel 9.

[0041] Further, such as Figure 1 As shown, the vibration device includes a support platform 18 connected to the support leg 16 and the lower end of the second U-shaped frame 19, and a plurality of support springs 21 are symmetrically distributed at the bottom of the support platform 18. The support springs 21 are all large elastic support springs. There are at least four support springs 21 and they are symmetrically distributed at the bottom edge of the support platform 18. Of course, the support springs 21 can be sufficient to support the support platform 18;

[0042] At least one vibration motor 17 is installed in the middle position of the top of the support platform 18. The two ends of the support spring 21 are respectively connected to the support platform 18 and the base 1. A shock absorber 20 is coaxially arranged in each support spring 21. The two ends of the shock absorber 20 are respectively rotatably connected to the support platform 18 and the base 1. The shock absorber 20 is a hydraulic shock absorber, which can prevent the support spring 21 from jumping significantly.

[0043] Further, such as Figure 1 and Figure 3 As shown, both ends of the bottom of the first U-shaped frame 5 are connected to a rotating block 4, the rotating block 4 is placed in the U-shaped support 3 and the two are connected by a rotating shaft, the U-shaped support 3 is connected to the base 1, and the U-shaped support 3 and the second U-shaped frame 19 are connected with a reinforcing frame 6.

[0044] Furthermore, if Figure 2 As shown, a holding brake 27 is provided on the rotating shaft of the rotating motor 14. The holding brake 27 and the rotating motor 14 form a holding brake motor. The two move synchronously. When the rotating motor 14 stops or loses power, the holding brake can lock and fix the support shaft 26.

[0045] Finally, when the utility model is in use, the fertilizer falls from the feed trough 11 into the feed channel 10, and finally enters the strip sealing cover 8 for screening one by one. The screened fertilizer falls from each discharge channel 9. After one side of the screen 25 has been used for a period of time, the rotating motor 14 is controlled to rotate 180° to allow the other side of the screen to continue screening, and the debris at the bottom of the screen falls down driven by the vibration motor, so that the screen is always kept clean.
