DETAILED DESCRIPTION

[0027] The following will refer to the attached Figures 1 to 6 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0028] A feeding and screening device for organic fertilizer production, as shown in the attached Figure 1 and 2 As shown, it includes a shell 1, and mounting plates 2 are respectively provided on the left and right sides of the shell 1. The mounting plates 2 are provided with slide grooves 3 in the up and down directions.

A collecting shell 9 is provided in the shell 1 and is located directly below the screening barrel 7. The lower end of the collecting shell 9 is detachably connected to a first baffle 10. The left end of the screening barrel 7 is provided with a through hole 11. A crushing mechanism is provided in the shell 1 and is located directly below the through hole 11. A feeding mechanism connected to the screening barrel 7 is provided at the upper end of the shell 1.

[0029] As attached Figure 2 As shown, the driving mechanism includes a first motor 12, which is arranged on the left slider 4, and the output end of the first motor 12 is coaxially fixedly connected to the rotating shaft 5. The first motor 12 can drive the screening barrel 7 to rotate through the rotating shaft 5 and the connecting cylinder 6.

[0030] As attached Figure 2 and 3As shown, the reset mechanism includes a reset spring 13, which is installed between the slider 4 and the mounting plate 2. The reset spring 13 always drives the slider 4 to move to the middle of the slide 3. When the first motor 12 drives the rotating shaft 5 and the screening barrel 7 to rotate, the reset spring 13 causes the rotating shaft 5 and the screening barrel 7 to shake in the up and down directions. The screening barrel 7 drives the fertilizer blocks inside to shake up and down, thereby enhancing the effect of organic fertilizer screening.

[0031] As attached Figure 1 As shown, the four corners of the shell 1 are respectively provided with support legs 14 in the upper and lower directions, and the lower ends of the support legs 14 are provided with anti-skid plates 15. The multiple support legs 14 can support the shell 1 to a certain height, so as to facilitate the staff to bag the screened fertilizer under the collection shell 9 and facilitate the staff to take the fertilizer.

[0032] As attached Figure 2 and 5 As shown, the crushing mechanism includes a crushing shell 16, the upper end of the crushing shell 16 can be communicated with the through hole 11, and the left and right sides of the crushing shell 16 are rotatably connected with front and rear axial cylindrical rods 17 respectively. A connecting gear 18 is provided at the rear end of the cylindrical rod 17, and the two connecting gears 18 are meshed with each other. A second motor 19 with a front and rear axial direction is provided at the rear end of the crushing shell 16, and the output end of the second motor 19 is fixedly connected to the cylindrical rod 17 on the left side. A crushing roller 20 located in the crushing shell 16 is provided on the cylindrical rod 17, and a gap is provided between the two crushing rollers 20. A second baffle 21 is detachably connected to the lower end of the crushing shell 16, and the second motor 19 drives the two crushing rollers 20 to rotate in opposite directions. Fertilizer blocks that do not meet the requirements fall into the crushing shell 16 from the through hole 11, and the two crushing rollers 20 can crush the fertilizer blocks that do not meet the requirements, so that the fertilizer blocks meet the requirements.

[0033] As attached Figure 2 As shown, the feeding mechanism includes a feeding barrel 22 which is larger at the top and smaller at the bottom. The feeding barrel 22 is arranged at the upper end of the outer shell 1. The lower end of the feeding barrel 22 is provided with a feeding pipe 23 located in the outer shell 1. The free end of the feeding pipe 23 extends into the screening barrel 7. The staff adds organic fertilizer into the feeding barrel 22, and the fertilizer blocks can reach the inside of the screening barrel 7 through the feeding pipe 23.

[0034] As attached Figure 2 As shown, the left side of the collecting shell 9 is inclined with the left side higher than the right side, and the screened fertilizer can slide through the inclined surface to the opening at the lower end of the collecting shell 9, thereby enhancing the collecting effect of the collecting shell 9.

[0035] As attached Figure 2 and 3 As shown, cams 24 are respectively provided on the left and right sides of the rotating shaft 5. The rotating shaft 5 drives the two cams 24 to rotate simultaneously. When the cams 24 rotate, the amplitude of the up and down shaking of the rotating shaft 5 can be increased, thereby achieving a better screening effect.

[0036] As attached Figure 4 As shown, two support frames 25 are provided at the right end of the connecting tube 6, and the free ends of the support frames 25 are fixedly connected to the inner wall of the screening barrel 7. The two support frames 25 can support the right part of the screening barrel 7 to prevent the screening barrel 7 from being damaged.

[0037] When the utility model is in use, the anti-skid plate 15 at the lower end of the plurality of supporting legs 14 is in contact with the horizontal ground, and the anti-skid plate 15 can prevent the housing 1 from moving during use. The staff removes the first baffle 10 from below the collecting shell 9 and the second baffle 21 from the lower end of the crushing shell 16. A container needs to be prepared in advance and placed on the ground directly below the crushing mechanism, and then the opening of the fertilizer bag is placed on the lower end of the collecting shell 9;

[0038] Start the first motor 12 and the second motor 19. The first motor 12 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the screening barrel 7 to rotate through the connecting cylinder 6. At the same time, the rotating shaft 5 drives the two cams 24 to rotate. The cams 24 are subjected to the centrifugal force and start to drive the slider 4 to move up and down through the rotating shaft 5. When the slider 4 slides up and down in the slide 3, it alternately squeezes the upper and lower return springs 13. At the same time, the rotating shaft 5 drives the screening barrel 7 to shake up and down through the connecting cylinder 6, that is, the screening barrel 7 shakes up and down while rotating. The second motor 19 drives the cylindrical rod 17 on the left to rotate. The cylindrical rod 17 on the left drives the cylindrical rod 17 on the right to rotate in the opposite direction through the two connecting gears 18. The two cylindrical rods 17 drive the two crushing rollers 20 to rotate in opposite directions.

[0039] The staff uses a tool to add the unscreened organic fertilizer into the feed barrel 22. Since the feed barrel 22 is set to be larger at the top and smaller at the bottom, the fertilizer blocks in the feed barrel 22 begin to enter the screening barrel 7 through the feed pipe 23. Since the screening barrel 7 rotates and shakes up and down, the fertilizer blocks that meet the requirements fall from the screening holes 8 into the collecting shell 9, and then enter the fertilizer bag through the opening at the lower end of the collecting shell 9. Since the screening barrel 7 is in a tapered shape with a larger left side and a smaller right side, the lower end of the side wall of the screening barrel 7 is lower on the left and higher on the right. The screening holes 8 through which the fertilizer blocks pass are constantly changing, which can avoid clogging of the screening holes 8. The fertilizer blocks that do not meet the requirements will roll to the left along the side wall of the screening barrel 7.

[0040] When the through hole 11 rotates to the top of the crushing mechanism along with the screening barrel 7, the fertilizer blocks that do not meet the requirements fall into the crushing mechanism from the through hole 11, and the fertilizer blocks reach between the two crushing rollers 20. The two crushing rollers 20 rotate in opposite directions and crush the fertilizer blocks. The crushed fertilizer blocks fall from the opening at the lower end of the crushing shell 16 into the container placed in advance. When the container is full, the staff can place the second baffle 21 at the lower end of the crushing shell 16, and then pour the fertilizer blocks in the container into the feeding barrel 22. The crushed fertilizer blocks re-enter the screening barrel 7 for screening. After pouring, the container is placed under the crushing shell 16 again. The fertilizer blocks that do not meet the requirements will enter the crushing mechanism again, and the crushing mechanism will crush the fertilizer blocks that do not meet the requirements again until all the fertilizer blocks meet the requirements, and then the first motor 12 and the second motor 19 can be turned off.

[0041] The first motor 12 and the second motor 19 in the present invention are both prior art and are connected to a power supply by a circuit. The power supply is used to supply power to the first motor 12 and the second motor 19, which will not be described in detail here.
