Description

Technical Field

[0001] This utility model relates to the field of nutrient soil technology, and in particular to an impurity screening device for nutrient soil production. Background Technology

[0002] Nutrient soil is a type of soil specially formulated to meet the growth and development needs of seedlings. It contains a variety of mineral nutrients, is loose and well-aerated, has strong water and fertilizer retention capacity, and is free from pests and diseases. Among them, the impurity screening device for nutrient soil production is a special device used to remove impurities and screen for suitable particle sizes during the nutrient soil production process.

[0003] When using existing technology, if you encounter nutrient soil with different particle sizes, you may need to replace the entire sieve plate. This not only increases production costs but also reduces production efficiency. The fixed sieve hole size may also cause some impurities to be unable to be effectively screened out or some useful fine particles to be mistakenly screened out, thus affecting the overall quality and uniformity of the nutrient soil. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing technology does not have a structure for adjusting the sieve holes, which results in some impurities not being effectively screened out, affecting the overall quality and uniformity of the nutrient soil. Therefore, we propose an impurity screening device for nutrient soil production.

[0005] To achieve the above objectives, this application adopts the following technical solution: an impurity screening device for nutrient soil production, comprising a shell: a feed pipe is fixedly connected to the top of the shell, a first support is slidably connected inside the feed pipe, a first filter screen is installed on the inner wall of the first support, a toothed groove is provided at one end of the top of the first support, a second support is fixedly connected to one end of the surface of the feed pipe, a sliding groove is provided at both ends inside the second support, a locking tooth is slidably connected to the inner wall of the sliding groove, an adjusting gear is rotatably connected to the inner wall of the second support via a rotating shaft, the surface of the locking tooth meshes with the inner wall of the adjusting gear, a second filter screen is installed inside the feed pipe, a vibrating motor is installed at both ends of the inner wall of the feed pipe, a feed hopper is fixedly connected to the top of the feed pipe, and a storage box is slidably connected inside the shell.

[0006] Preferably, a first limiting groove is provided on both sides of the inner wall of the slide groove, and a first slider is slidably connected to the inner wall of the first limiting groove. One side of the first slider is fixedly connected to one side of the locking tooth.

[0008] Preferably, a second limiting groove is provided on both sides of the inner wall of the feeding pipe, and a second sliding buckle is fixedly connected to both sides of the first bracket, with the surface of the second sliding buckle slidably connected to the inner wall of the second limiting groove.

[0009] Preferably, servo motors are installed at both ends on one side of the feed hopper, and augers are installed at the output ends of the servo motors.

[0010] Preferably, a drive motor is installed inside the storage box, and a stirring rod is installed at the output end of the drive motor.

[0011] Preferably, heating devices are installed on both sides inside the housing, and four guide fans are installed inside the heating devices.

[0012] Technical effects and advantages of this utility model: In this invention, the user adjusts the adjusting gear inside the second bracket mounted on the surface of the feeding pipe. The adjusting gear adjusts the position of the first bracket inside the feeding pipe through the tooth groove at the top of the first bracket, sieving the nutrient soil and leaving impurities on the top of the second filter screen. The sieved nutrient soil falls into the storage box. By adjusting the fit between the screen holes of the second and first filter screens, the screen hole size can be flexibly adjusted according to the particle size and impurity type of different nutrient soils. This makes the screening device highly adaptable, accurately screening both coarse and fine nutrient soils, effectively removing impurities, and ensuring the quality and uniformity of the nutrient soil.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figures 1-6 As shown, this utility model provides a technical solution: an impurity screening device for producing nutrient soil, comprising a shell 1; a feeding pipe 2 is fixedly connected to the top of the shell 1, a first support 3 is slidably connected inside the feeding pipe 2, a first filter screen 4 is installed on the inner wall of the first support 3, a toothed groove 5 is opened at one end of the top of the first support 3, a second support 6 is fixedly connected to one end of the surface of the feeding pipe 2, a sliding groove 7 is opened at both ends inside the second support 6, a locking tooth 8 is slidably connected to the inner wall of the sliding groove 7, an adjusting gear 9 is rotatably connected to the inner wall of the second support 6 via a rotating shaft, the surface of the locking tooth 8 meshes with the inner wall of the adjusting gear 9, a second filter screen 10 is installed inside the feeding pipe 2, a vibrating motor 11 is installed at both ends of the inner wall of the feeding pipe 2, a feeding hopper 12 is fixedly connected to the top of the feeding pipe 2, and a storage box 13 is slidably connected inside the shell 1. When the user puts nutrient soil into the device along the storage box 13, the nutrient soil falls into the lower part of the device. On the surface of the second filter screen 10 inside the feed pipe 2, the user adjusts the adjusting gear 9 inside the second bracket 6 installed on the surface of the feed pipe 2. The adjusting gear 9 adjusts the position of the first bracket 3 inside the feed pipe 2 through the tooth groove 5 at the top of the first bracket 3, so that the fit between the screen holes of the first filter screen 4 and the second filter screen 10 is adjusted. Then, the vibration motor 11 is driven by the control panel on one side of the storage box 13 to vibrate the second filter screen 10, screening out the nutrient soil and leaving the impurities on the top of the second filter screen 10. The screened nutrient soil falls into the storage box 13. By adjusting the fit between the screen holes of the second filter screen 10 and the first filter screen 4, the screen hole size can be flexibly adjusted according to the particle size and impurity type of different nutrient soil, so that the screening device has a high degree of adaptability. Whether it is coarse or fine nutrient soil, it can accurately screen and effectively remove impurities, ensuring the quality and uniformity of the nutrient soil.

[0017] Reference Figure 4 , Figure 5 and Figure 6 As shown in this embodiment: a first limiting groove 14 is provided on both sides of the inner wall of the slide groove 7. A first slider 15 is slidably connected to the inner wall of the first limiting groove 14. One side of the first slider 15 is fixedly connected to one side of the locking tooth 8. When the user moves the locking tooth 8 through the first slider 15 at both ends on the inner wall of the first limiting groove 14, the locking tooth 8 will not fall out when it moves on the inner wall of the slide groove 7.

[0018] Reference Figure 4 , Figure 5 and Figure 6 As shown in this embodiment: a spring 16 is fixedly connected to one side of the inner wall of the slide groove 7, and the other end of the spring 16 is fixedly connected to one side of the retaining tooth 8. When the user moves the retaining tooth 8 along the inner wall of the slide groove 7, causing the retaining tooth 8 to release the fixing of the adjusting gear 9, the user moves the retaining tooth 8 outward, causing the retaining tooth 8 to pull the spring 16, causing the spring 16 to store force and stretch. When the user needs to move the retaining tooth 8 back to its original position, he only needs to release the retaining tooth 8, causing the spring 16 to release and retract, pulling the retaining tooth 8 back to its original position. The spring 16 enables the retaining tooth 8 to have an automatic reset function, making it easier for the user to operate the equipment.

[0019] Reference Figure 4 , Figure 5 and Figure 6 As shown in this embodiment: a second limiting groove 17 is provided on both sides of the inner wall of the feeding tube 2, and a second sliding buckle 18 is fixedly connected to both sides of the first bracket 3. The surface of the second sliding buckle 18 is slidably connected to the inner wall of the second limiting groove 17. When the user adjusts the position of the first bracket 3 inside the feeding tube 2, the first bracket 3 moves through the second sliding buckle 18 on both sides of the inner wall of the second limiting groove 17, so that the movement trajectory of the first bracket 3 is fixed, making the first bracket 3 more stable when moving.

[0020] Reference Figure 4 As shown in this embodiment: servo motors 19 are installed at both ends on one side of the feed hopper 12, and augers 20 are installed at the output end of the servo motors 19. When the user is about to put the nutrient soil into the equipment, the servo motors 19 are started, and the servo motors 19 drive the augers 20 to crush the nutrient soil poured into the storage box 13, so that the large particles in the nutrient soil are crushed into smaller particles, which facilitates subsequent screening.

[0021] Reference Figure 6As shown in this embodiment: a drive motor 21 is installed inside the storage box 13, and a stirring rod 22 is installed at the output end of the drive motor 21. When the user starts the equipment, after the nutrient soil is screened and falls into the storage box 13, the drive motor 21 drives the stirring rod 22 to stir the nutrient soil inside the storage box 13, so that the nutrient soil is more evenly distributed in the storage box 13, avoiding local accumulation or uneven distribution, thereby improving the overall quality of the nutrient soil.

[0022] Reference Figure 6 As shown in this embodiment: heating devices 23 are installed on both sides inside the shell 1. Four guide fans 24 are installed inside the heating devices 23. After the user selects the nutrient soil and piles it inside the storage box 13, the hot air emitted by the heating devices 23 of the drying device is guided into the storage box 13 by the guide fans 24 to dry the piled nutrient soil, remove excess water from the nutrient soil, and make the nutrient soil reach a suitable humidity standard, which is more conducive to plant growth.

[0023] Working principle: Step 1: When the user puts the nutrient soil into the equipment along the storage box 13, the nutrient soil will fall on the surface of the second filter screen 10 inside the feed pipe 2. The user can adjust the position of the first support 3 inside the feed pipe 2 by adjusting the adjusting gear 9 inside the second support 6 installed on the surface of the feed pipe 2 and using the tooth groove 5 on the top of the first support 3. This will adjust the fit between the first filter screen 4 and the screen holes of the second filter screen 10. After the adjustment is completed, the vibration motor 11 is started through the control panel on one side of the storage box 13 to make the second filter screen 10 vibrate, screen the nutrient soil, and leave the impurities on the top of the second filter screen 10. The screened nutrient soil then falls into the storage box 13. Step two: When the user needs to operate the equipment, firstly, the first slider 15 at both ends moves the locking tooth 8 on the inner wall of the first limiting groove 14, so that it slides on the inner wall of the slide groove 7 without coming off. When the user moves the locking tooth 8 along the slide groove 7 and releases the fixing of the adjusting gear 9, the user pulls the locking tooth 8 outward. At this time, the locking tooth 8 will pull the spring 16, so that the spring 16 stores and stretches. When the user needs to reset the locking tooth 8, simply release the locking tooth 8, and the spring 16 will release the retraction force, automatically pulling the locking tooth 8 back to its original position, realizing the automatic reset function, so that the user can operate the equipment more simply and conveniently. At the same time, when adjusting the position of the first bracket 3 inside the feed tube 2, the first bracket 3 moves on the inner wall of the second limiting groove 17 through the second sliding buckles 18 on both sides, ensuring that its movement trajectory is fixed, so that the first bracket 3 is more stable during the movement. Step 3: When the user prepares to put the nutrient soil into the equipment, the servo motor 19 is started first. The servo motor 19 drives the auger 20 to crush the nutrient soil poured into the storage box 13, breaking the large particles into smaller particles for subsequent screening. Then, the user starts the equipment to screen the soil. The screened nutrient soil falls into the storage box 13. At this time, the drive motor 21 drives the stirring rod 22 to stir the nutrient soil in the storage box 13, making it more evenly distributed and avoiding local accumulation or uneven distribution, thereby improving the overall quality of the nutrient soil. The hot air emitted by the drying device heating device 23 is directed into the storage box 13 by the guide fan 24 to dry the accumulated nutrient soil and remove excess moisture.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
