Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer particle screening technology, and in particular to an inclined organic fertilizer particle grading and screening machine. Background Technology

[0002] Inclined organic fertilizer granule grading and screening machine is a device specifically used in the organic fertilizer production process to grade and screen granules of different sizes. Its core function is to classify organic fertilizer raw materials or finished products according to size through screening to meet the specification requirements of different uses (such as coarse granules for base fertilizer, fine granules for top dressing, etc.).

[0003] The existing inclined organic fertilizer granule grading and screening machine has obvious design flaws. Its eccentric block and motor output shaft are fixedly connected and lack a position adjustment structure. As a result, the vertical height between the eccentric block and the motor shaft cannot be adjusted. This rigid connection method severely limits the adjustment performance of the equipment. Operators can only change the amplitude by adjusting the motor speed. Not only is the adjustment range limited, but it is also difficult to meet the precise screening requirements of materials with different particle sizes, which seriously affects the screening efficiency and quality.

[0004] Therefore, to address the problem that the eccentric block position of the existing inclined organic fertilizer granule grading and screening machine is fixed and the vertical height cannot be adjusted, resulting in insufficient flexibility as the amplitude can only be adjusted by the motor speed, an inclined organic fertilizer granule grading and screening machine can be designed. Utility Model Content

[0005] In order to overcome the problem that the eccentric block of the existing inclined organic fertilizer granule grading and screening machine is fixed in position and cannot be adjusted in vertical height, resulting in insufficient flexibility as the amplitude can only be adjusted by the motor speed.

[0006] The technical solution of this utility model is as follows: an inclined organic fertilizer granule grading and screening machine, including a bottom support, a lead screw and a slide block. An elastic component is provided on the top of the bottom support, and a connecting component is installed on the top of the elastic component. A screening frame is provided between the connecting components. A drive motor is installed on the front side of the screening frame. The output end of the drive motor is connected to a transmission shaft. The drive motor is used to drive the transmission shaft to rotate. A rotating component is installed on the rear end of the transmission shaft. Two collars are installed on the outside of the transmission shaft. A limit frame is installed on the bottom of each collar. A lead screw is rotatably connected to the top of the inner part of the limit frame. A gear is installed on the upper outer end of the lead screw. A slide block is threadedly connected to the outside of the lead screw. An eccentric block is installed on the bottom of the slide block.

[0007] Preferably, by setting up gears, the operator can use tools to rotate the gears. When the gears rotate, they can drive the lead screw to rotate. The rotation of the lead screw can drive the slide block that is threaded with it to move up and down, thereby driving the eccentric block to move synchronously. This allows for adjustment of the distance between the eccentric block and the output shaft of the drive motor, thereby adjusting the amplitude. This solves the problem that the existing inclined organic fertilizer granule grading and screening machine does not have a structure for adjusting the position of the eccentric block, and the vertical height between the eccentric block and the motor output shaft cannot be adjusted. As a result, the amplitude can only be adjusted by adjusting the motor speed, which is quite limiting.

[0008] Preferably, the elastic component includes a raised seat, a mounting seat, and a spring; two raised seats are installed on the top left side of the bottom bracket, and mounting seats are provided on the top of the two raised seats and the top right side of the bottom bracket. A spring is sleeved on the outside of the mounting seat. By setting the spring and the mounting seat, the connecting component can be connected.

[0009] Preferably, the connecting assembly includes a positioning seat, a connecting shaft, and a pressure cover; the top of the spring is connected to the positioning seat, the top of the positioning seat is rotatably connected to the connecting shaft, and the top of the positioning seat is also equipped with a pressure cover for positioning the connecting shaft. The connecting shaft is fixed to the screening frame. By setting the positioning seat, the connecting shaft is positioned. When the eccentric block rotates, the screening frame can vibrate at the same frequency through the soft connection of the spring.

[0010] Preferably, the screening frame is equipped with a screening component, which includes three screens with different aperture sizes. The screens are fixed to the screening frame and arranged from top to bottom according to their aperture sizes. By setting three screens, multi-stage screening can be achieved, thereby improving the screening quality of the device.

[0011] Preferably, the rotating assembly includes a bearing housing and fixing screws; the rear end of the drive shaft is connected to a bearing housing for assisting its rotation, and multiple fixing screws distributed in a circle are installed on the front side of the bearing housing. The bearing housing is fixed to the screening frame by the fixing screws. By setting the bearing housing, the bearing inside can assist the drive shaft to rotate, thereby improving the stability of the drive shaft rotation.

[0012] Preferably, limit blocks are provided on both the left and right sides of the slide, and limit grooves are provided on both the left and right sides of the inner side of the limit frame. The limit blocks and limit grooves are slidably connected. By setting the limit blocks and limit grooves, the slide can drive the limit blocks to slide inside the limit grooves when it moves. The limit grooves can restrict the sliding direction of the limit blocks, thereby improving the stability of the slide movement.

[0013] Preferably, a material distribution pipe is installed at the right end of the screening frame, two guide plates are installed at the top of the material distribution pipe, a coarse material channel is installed at the right end of the two guide plates, and a powder material channel is set at the bottom of the screening frame. By setting up the coarse material channel, the material distribution pipe and the powder material channel, the material can be guided and discharged, so that organic fertilizer particles of different sizes can be piled up separately.

[0014] The beneficial effects of this utility model are:

[0015] By setting an adjustable eccentric block and adjusting the vertical distance between the eccentric block and the output shaft of the drive motor, operators can flexibly control the magnitude of the centrifugal force of the equipment, thereby achieving precise amplitude adjustment. This design not only simplifies the operation process but also significantly improves the equipment's adaptability to different working conditions and effectively optimizes the vibration effect. At the same time, this adjustment method avoids complex mechanical structure adjustments, significantly reduces maintenance costs, and extends the service life of the equipment. In addition, precise amplitude control helps improve processing quality, ensures product consistency, and provides strong support for the stability and reliability of the production process.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment: an inclined organic fertilizer granule grading and screening machine, including a bottom support 1, a lead screw 11, and a slide block 13. An elastic component is provided on the top of the bottom support 1, and a connecting component is installed on the top of the elastic component. A screening frame 4 is arranged between the connecting components. A drive motor 6 is installed on the front side of the screening frame 4, and a transmission shaft 7 is connected to the output end of the drive motor 6. The drive motor 6 drives the transmission shaft 7 to rotate. A rotating component is installed at the rear end of the transmission shaft 7. Two collars 9 are installed on the outer side of the transmission shaft 7, and a limiting frame 10 is installed at the bottom of each of the two collars 9. The inner top of the limiting frame 10... A lead screw 11 is rotatably connected, and a gear 12 is installed on the upper outer side of the lead screw 11. A slide block 13 is threadedly connected to the outer side of the lead screw 11, and an eccentric block 14 is installed at the bottom of the slide block 13. By setting the gear 12, a special tool is used to drive the gear 12 to rotate. The gear 12 drives the lead screw 11, which meshes with it, to rotate. Since the slide block 13 and the lead screw 11 form a threaded pair, the rotation of the lead screw 11 will be converted into the linear displacement of the slide block 13. The up and down movement of the slide block 13 will synchronously drive the position of the eccentric block 14 to change, thereby adjusting the center distance between the eccentric block 14 and the output shaft of the drive motor 6, and finally achieving precise control of the amplitude of the vibration system.

[0024] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, the elastic component includes a raised seat 201, a mounting seat 202, and a spring 203. Two raised seats 201 are installed on the top left side of the bottom bracket 1. Mounting seats 202 are provided on the top of both raised seats 201 and the top right side of the bottom bracket 1. Springs 203 are sleeved on the outer side of the mounting seats 202. By setting the springs 203 and the mounting seats 202, the connecting component can be connected. The connecting component includes a positioning seat 301, a connecting shaft 302, and a pressure cap 303. The top of the spring 203 is connected to the positioning seat 301, and the top of the positioning seat 301 is rotatably connected to the connecting shaft 302. The top of the seat 301 is also equipped with a pressure cover 303 for positioning the connecting shaft 302. The connecting shaft 302 is fixed to the screening frame 4. The positioning seat 301 is used to position the connecting shaft 302. When the eccentric block 14 rotates, the screening frame 4 can vibrate at the same frequency through the soft connection of the spring 203. The screening frame 4 is equipped with a screening component inside. The screening component includes three screens 51 with different apertures. The screens 51 are fixed to the screening frame 4. The three screens 51 are arranged from top to bottom according to the aperture size. By setting three screens 51, the function of multi-stage screening can be realized, and the screening quality of the device can be improved.

[0025] Please see Figures 1-5In this embodiment, the rotating assembly includes a bearing seat 81 and fixing screws 82. The rear end of the drive shaft 7 is connected to a bearing seat 81 to assist its rotation. Multiple circumferentially distributed fixing screws 82 are installed on the front side of the bearing seat 81. The bearing seat 81 is fixed to the screening frame 4 by the fixing screws 82. By setting the bearing seat 81, the bearing inside can assist the drive shaft 7 in rotating, thereby improving the stability of the drive shaft 7's rotation. Limiting blocks 16 are provided on both the left and right sides of the slide block 13. Limiting grooves 15 are opened on both the left and right sides of the inner side of the limiting frame 10. The limiting blocks 16 and the limiting grooves 15 are slidably connected. By setting the limiting blocks 16, the rotation of the drive shaft 7 is improved. The positioning block 16 and the limiting groove 15, when the slide 13 moves, can drive the limiting block 16 to slide inside the limiting groove 15. The limiting groove 15 can restrict the sliding direction of the limiting block 16, thereby improving the stability of the slide 13's movement. The right end of the screening frame 4 is equipped with a material distribution pipe 17. The top of the material distribution pipe 17 is equipped with two guide plates 18. The right end of the two guide plates 18 is equipped with a coarse material channel 19. The bottom of the screening frame 4 is equipped with a powder material channel 20. By setting the coarse material channel 19, the material distribution pipe 17 and the powder material channel 20, the material can be guided and discharged, so that organic fertilizer particles of different sizes can be piled up separately.

[0026] When working, the drive motor 6 is started, and the drive motor 6 drives the transmission shaft 7 to rotate with the cooperation of the bearing seat 81. When the transmission shaft 7 rotates, it drives the two eccentric blocks 14 on its outer side to rotate synchronously. The resulting amplitude is transmitted to the screening frame 4 through the spring 203 and the connecting shaft 302, which drives the screen 51 in the screening frame 4 to vibrate, thereby realizing the screening of organic fertilizer particles. Organic fertilizer of different particle sizes can be guided to discharge by the material distribution pipe 17, the coarse material channel 19 and the powder material channel 20. When it is necessary to adjust the amplitude, the gear 12 can be rotated. The gear 12 drives the lead screw 11 to rotate, and the lead screw 11 drives the slide 13 to move up and down. The amplitude can be adjusted by adjusting the vertical distance between the eccentric block 14 and the output shaft of the drive motor 6.

[0027] Through the above steps, by setting gear 12, the operator manually rotates gear 12 with tools, which drives the lead screw 11 to rotate. Since the slide block 13 and the lead screw 11 are threaded together, the rotational motion of the lead screw 11 is converted into the linear lifting and lowering of the slide block 13. The up-and-down movement of the slide block 13 drives the eccentric block 14 to move synchronously, thereby changing the radial distance between the eccentric block 14 and the output shaft of the drive motor 6, and finally realizing the adjustment of the vibration amplitude of the equipment. This solves the problem that the existing inclined organic fertilizer granule grading and screening machine does not have a position adjustment structure for the eccentric block 14 during use, and the vertical height between the eccentric block 14 and the motor output shaft cannot be adjusted, resulting in the limitation that the amplitude can only be adjusted by adjusting the motor speed during use.
