A motor is mounted on the support frame, and a drive wheel is fixedly connected to the output end of the motor. A belt is slidably connected to the drive wheel, and a driven wheel is slidably connected to the belt. A screening cylinder is fixedly connected to the driven wheel, and a support rod is fixedly connected to the screening cylinder. A sleeve is provided outside the screening cylinder, and a limiting groove is provided on the sleeve. The support rod is slidably connected to the sleeve through the limiting groove. A bucket lid is fixedly connected to one end of the screening cylinder, and a second motor is mounted on one side of the support frame.

[0004] Existing bio-organic fertilizer screening equipment mostly involves feeding organic fertilizer into a feed cylinder, and then pushing the fertilizer through a spiral feeder while stirring it until it exits from the discharge cylinder. Small particles in the fertilizer pass through a screen cylinder during this process, thus achieving fertilizer screening. The screen cylinder is usually fixed to the feed and discharge cylinders by welding, and the mesh size of the screen cylinder is relatively fixed, making it impossible to replace the screen cylinder with different mesh sizes according to usage requirements. Therefore, there is an urgent need to propose corresponding bio-organic fertilizer screening equipment to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a biological organic fertilizer screening device in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A biological organic fertilizer screening device includes a feed cylinder, a discharge cylinder, and a screen cylinder. A driving component is fixedly connected to the outer wall of the discharge cylinder, and a spiral feeding rod is fixedly connected to the output end of the driving component. The screen cylinder includes a first part and a second part, which are detachably connected between the feed cylinder and the discharge cylinder. A base frame is fixedly connected to the bottom of both the feed cylinder and the discharge cylinder. A feed tray is fixedly connected between the two sets of base frames. A bottom tube is fixedly connected to the bottom of the feed tray, and a guide pipe is provided on the outside of the bottom tube.

[0008] Preferably, the inner surface of the vertical end of the guide tube is rotatably connected to the outer surface of the bottom tube via a bearing, and a limiting sleeve is fixedly connected to the bottom of the feeder. The outer surface of the limiting sleeve is provided with a limiting part for axial limiting of the guide tube.

[0009] Preferably, the limiting part includes a positioning rod that is screwed into the outer wall of the limiting sleeve, and the open end of the positioning rod abuts against the outer wall of the vertical end of the guide tube.

[0010] Preferably, each of the two sets of base frames is fixedly connected to a connecting frame by screws on its opposite surfaces, and the feeder is fixedly connected between the two sets of connecting frames.

[0011] Preferably, both sides of the horizontal ends of the first and second parts are fixedly connected with connecting sleeves, and the two sets of connecting sleeves are respectively fixedly connected to the outer walls of the feed cylinder and the discharge cylinder through two sets of locking rods.

[0012] Preferably, both sets of connecting sleeves have protrusions fixedly connected to their inner surfaces, and the outer surfaces of the feed cylinder and the discharge cylinder are provided with grooves that fit the protrusions.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the two separate parts are combined. The connecting sleeves on both sides of the two separate parts overlap the outer sides of the feed cylinder and the discharge cylinder, respectively. The fit between the protrusion and the slot facilitates the quick determination of the circumferential position of the two separate parts. Then, multiple sets of locking rods are used to fix the two sets of connecting sleeves to the feed cylinder and the discharge cylinder, thereby realizing the assembly of the screen cylinder and the fixation of the feed cylinder and the discharge cylinder. The driving component drives the spiral feeding rod to rotate, and the spiral feeding rod realizes the agitation and pushing of the fertilizer until it is discharged from the discharge cylinder. Small particles in the fertilizer will pass through the screen cylinder in this process, thereby realizing the screening of fertilizer. At the same time, the screen cylinder can be easily disassembled and replaced according to the usage requirements.

[0015] 2. In this application, the guide tube is rotated to engage with the bottom tube via the bearing until the orientation of the guide tube meets the requirements. The positioning rod is then rotated to engage with the inner wall of the limiting sleeve. The position of the guide tube is locked by the contact friction between the open end of the positioning rod and the outer wall of the guide tube. The particles passing through the mesh cylinder enter the feeder and are discharged by passing through the bottom tube and the guide tube in sequence. This ensures stable collection of separated particles and allows for adjustment of the guiding direction according to usage requirements. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A biological organic fertilizer screening device includes a feeding cylinder 1, a discharging cylinder 2, and a screen cylinder 3. A driving component 9 is fixedly connected to the outer wall of the discharging cylinder 2, and a spiral feeding rod is fixedly connected to the output end of the driving component 9. The screen cylinder 3 includes a first part 301 and a second part 302, which are detachably connected between the feeding cylinder 1 and the discharging cylinder 2. A base frame 6 is fixedly connected to the bottom of both the feeding cylinder 1 and the discharging cylinder 2. A feeder 7 is fixedly connected between the two sets of base frames 6. A bottom tube 13 is fixedly connected to the bottom of the feeder 7, and a guide tube 8 is provided on the outside of the bottom tube 13.

[0025] The first part 301 and the second part 302 are combined. The connecting sleeves 4 on both sides of the first part 301 and the second part 302 overlap on the outside of the feed cylinder 1 and the discharge cylinder 2 respectively. The engagement of the protrusion and the slot 10 makes it easy for the two parts to quickly determine their circumferential positions. Then, the two sets of connecting sleeves 4 are fixed to the feed cylinder 1 and the discharge cylinder 2 by multiple sets of locking rods 5. This realizes the assembly of the screen cylinder 3 and the fixing of the feed cylinder 1 and the discharge cylinder 2. The driving part 9 drives the spiral feeding rod to rotate. The spiral feeding rod realizes the stirring and pushing of the fertilizer until it is discharged from the discharge cylinder 2. Small particles in the fertilizer will pass through the screen cylinder 3 in this process, thus realizing the screening of fertilizer. At the same time, the screen cylinder 3 can be easily disassembled and replaced according to the usage requirements.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the inner wall of the vertical end of the guide tube 8 is rotatably connected to the outer wall of the bottom tube 13 via a bearing 14. The bottom of the feed tray 7 is fixedly connected to a limiting sleeve 11. The outer wall of the limiting sleeve 11 is provided with a limiting part for axial limiting of the guide tube 8. The limiting part includes a positioning rod 12 that is screwed into the outer wall of the limiting sleeve 11. The open end of the positioning rod 12 abuts against the outer wall of the vertical end of the guide tube 8. The guide tube 8 is moved so that it rotates and engages with the bottom tube 13 via the bearing 14 until the orientation of the guide tube 8 reaches the appropriate requirement. The positioning rod 12 is rotated so that it engages with the inner wall of the limiting sleeve 11. The position of the guide tube 8 is locked by the contact friction between the open end of the positioning rod 12 and the outer wall of the guide tube 8. The particles passing through the mesh cylinder 3 enter the feed tray 7 and are discharged by passing through the bottom tube 13 and the guide tube 8 in sequence. This ensures stable collection of separated particles and allows for adjustment of the guiding direction according to usage requirements.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the two sets of base frames 6 are fixedly connected to the connecting frames on opposite sides by screws. The feeder 7 is fixedly connected between the two sets of connecting frames to ensure the ease of disassembly and assembly of the feeder 7. The horizontal ends of the split body 1 301 and the split body 2 302 are fixedly connected to the connecting sleeves 4. The two sets of connecting sleeves 4 are fixedly connected to the outer walls of the feed cylinder 1 and the discharge cylinder 2 by two sets of locking rods 5 respectively, thus ensuring the ease of disassembly and assembly of the mesh cylinder 3. The inner walls of the two sets of connecting sleeves 4 are fixedly connected to protrusions, and the outer walls of the feed cylinder 1 and the discharge cylinder 2 are provided with slots 10 that fit with the protrusions, which can facilitate the quick determination of the circumferential position of the two sets of parts.

[0028] Working principle: The first component 301 and the second component 302 are combined. The connecting sleeves 4 on both sides of the first component 301 and the second component 302 overlap the outer sides of the feed cylinder 1 and the discharge cylinder 2, respectively. The engagement of the protrusions and the slots 10 facilitates the quick determination of the circumferential position of the two components. Then, multiple sets of locking rods 5 are used to fix the two sets of connecting sleeves 4 to the feed cylinder 1 and the discharge cylinder 2, thereby assembling the mesh cylinder 3 and fixing the feed cylinder 1 and the discharge cylinder 2. The driving component 9 drives the spiral feeding rod to rotate, which agitates and pushes the fertilizer until it is discharged from the discharge cylinder 2. Small particles in the fertilizer will pass through the mesh cylinder 3 during this process. This allows for the screening of fertilizers while enabling convenient disassembly and replacement of the entire mesh cylinder 3 according to usage requirements. The guide tube 8 is rotated and engaged with the bottom tube 13 via the bearing 14 until the orientation of the guide tube 8 meets the requirements. The positioning rod 12 is then rotated to engage with the inner wall of the limiting sleeve 11. The position of the guide tube 8 is locked by the contact friction between the open end of the positioning rod 12 and the outer wall of the guide tube 8. The particles passing through the mesh cylinder 3 enter the feed tray 7 and are discharged by passing through the bottom tube 13 and the guide tube 8 in sequence. This ensures stable collection of separated particles and allows for adjustment of the guiding direction according to usage requirements.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
