Technical Field
[0001] This utility model relates to the field of water-soluble fertilizer granule screening technology, and specifically discloses a water-soluble fertilizer granule screening device. Background Technology
[0002] Water-soluble fertilizer is a multi-element compound fertilizer that can be completely dissolved in water. It can dissolve quickly in water, making it easier for crops to absorb, and its absorption and utilization rate is relatively high. More importantly, it can be applied to facility agriculture such as sprinkler and drip irrigation to achieve integrated water and fertilizer management, thus saving water, fertilizer and labor. With the development of the times and the progress of technology, the use of organic water-soluble fertilizer is becoming more and more widespread, and the demand is also increasing.
[0003] Existing screening equipment is usually single-function, often only capable of vibrating screening. For damp materials, the screens are prone to clogging. Furthermore, fertilizers entering the screening equipment may clump due to moisture, affecting screening efficiency. Therefore, a water-soluble fertilizer granule screening device is needed to solve this problem. Utility Model Content

[0005] This utility model is implemented as follows: a water-soluble fertilizer granule screening device includes a fixed frame, a screening mechanism is provided on the right side of the upper end face of the fixed frame, and a dispersing mechanism is provided on the left side of the upper end face of the fixed frame. The dispersing mechanism includes a conveying cylinder fixedly installed on a fixed frame, a spiral conveying plate rotatably connected inside the conveying cylinder, a servo motor installed on the outer wall of the conveying cylinder and whose output end is fixedly connected to the spiral conveying plate, a drying outer cylinder fixedly sleeved on the outer wall of the conveying cylinder, multiple guide plates inclinedly arranged on the inner wall of the drying outer cylinder, and a liquid injection port arranged on the outer wall of the drying outer cylinder and whose end is threadedly connected to a sealing cap. The screening mechanism includes a screening box mounted on a fixed frame and located at the lower right of the conveying cylinder, two screening plates detachably connected to the inside of the screening box by bolts, a vibrating motor installed at the bottom of the screening box, and multiple elastic components installed between the fixed frame and the bottom of the screening box. The screening box is also equipped with an anti-clogging mechanism, which includes a threaded rod rotatably connected to the front of the screening box via a bearing, a movable plate threaded to the outer wall of the threaded rod, a cleaning steel brush located on the rear end of the movable plate, a drive motor installed on the right side of the screening box with its output end fixedly connected to the threaded rod, and a slide rod fixedly connected inside the screening box and symmetrically arranged with the threaded rod. The slide rod and the movable plate are slidably connected.
[0006] In a preferred embodiment of the water-soluble fertilizer granule screening equipment of this utility model, the number of cleaning steel brushes is the same as the number of screening plates, and each cleaning steel brush is located above the corresponding screening plate.
[0007] As a preferred embodiment of the water-soluble fertilizer granule screening equipment of this utility model, the screening box has three discharge ports through the right side, with the two upper discharge ports located on the upper end face of the two screening plates respectively.
[0008] In a preferred embodiment of the water-soluble fertilizer granule screening equipment of this utility model, the elastic component is a spring.
[0009] In a preferred embodiment of the water-soluble fertilizer granule screening equipment of this utility model, the outer wall of the conveying cylinder is connected to a feed hopper and a discharge pipe, and the lower end of the discharge pipe extends into the through groove in the middle of the upper surface of the screening box.
[0010] In a preferred embodiment of the water-soluble fertilizer granule screening equipment of this utility model, a controller is installed on the outer wall of the fixed frame, and the servo motor, drive motor and vibration motor are all electrically connected to the controller.
[0011] The beneficial effects of this utility model are: By setting a drying outer cylinder with a guide plate outside the conveying cylinder, and in conjunction with a spiral conveyor plate, a hot medium can be introduced during the conveying process to dry the moist particles evenly and gently. This integrated design completes the initial drying and dispersion before the material enters the screening mechanism, effectively reducing screen blockage caused by the moisture and clumping of the material, and improving screening efficiency from the source. By driving the threaded rod with a drive motor, the moving plate equipped with multiple cleaning steel brushes can reciprocate to clean the multi-layer screening plate, remove particles that clog the screen holes, and achieve high anti-clogging efficiency.

Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0018] Please see Figure 1-3 A water-soluble fertilizer granule screening device includes a fixed frame, a screening mechanism is provided on the right side of the upper end face of the fixed frame, and a dispersing mechanism is provided on the left side of the upper end face of the fixed frame. The dispersing mechanism includes a conveying cylinder 1 fixedly installed on a fixed frame, a spiral conveying plate 102 rotatably connected inside the conveying cylinder 1, a servo motor 103 installed on the outer wall of the conveying cylinder 1 and whose output end is fixedly connected to the spiral conveying plate 102, a drying outer cylinder 2 fixedly sleeved on the outer wall of the conveying cylinder 1, a plurality of guide plates 201 inclinedly arranged on the inner wall of the drying outer cylinder 2, and a liquid injection port arranged on the outer wall of the drying outer cylinder 2 and whose end is threadedly connected to a sealing cap. The screening mechanism includes a screening box 3 set on a fixed frame and located at the lower right of the conveying cylinder 1, two screening plates 301 detachably connected to the inside of the screening box 3 by bolts, a vibration motor 303 installed at the bottom of the screening box 3, and multiple elastic components 304 installed between the fixed frame and the bottom of the screening box 3. The screening box 3 is also equipped with an anti-blocking mechanism. The anti-blocking mechanism includes a threaded rod 4 rotatably connected to the front of the screening box 3 via a bearing, a movable plate 402 threaded to the outer wall of the threaded rod 4, a cleaning steel brush 403 located on the rear end face of the movable plate 402, a drive motor 401 installed on the right side of the screening box 3 and whose output end is fixedly connected to the threaded rod 4, and a slide rod fixedly connected inside the screening box 3 and symmetrically arranged with the threaded rod 4. The slide rod and the movable plate 402 are slidably connected.
[0019] In this embodiment: water-soluble fertilizer granules enter the conveying cylinder 1, and the servo motor 103 drives the spiral conveyor plate 102 to convey them to the right. During this process, if the granules are wet, hot water or heat transfer oil can be introduced into the drying outer cylinder 2 from the liquid injection port. The heat is transferred to the material through the wall of the conveying cylinder 1. At the same time, the guide plate 201 changes the flow direction of the heat medium, prolongs the heat exchange time, and achieves preliminary drying and dispersion. Subsequently, the material falls into the screening box 3 through the discharge pipe 104. The vibration motor 303 works, driving the entire screening box 3 to vibrate on the elastic component 304. The two screening plates 301 with different apertures screen the material into three sizes: large, medium and small. The particles of the three sizes are discharged from the three discharge ports 302 respectively. The drive motor 401 operates, driving the threaded rod 4 to rotate, causing the moving plate 402 and the cleaning steel brush 403 on it to move back and forth along the slide rod, brushing away the particles clogging the screen holes of the screening plate 301 and preventing clogging.
[0020] As a technical optimization of this utility model, the number of cleaning steel brushes 403 is the same as the number of screening plates 301, and each cleaning steel brush 403 is located above the corresponding screening plate 301.
[0021] In this embodiment, by matching the number of cleaning steel brushes 403 with the number of screening plates 301, multiple screening plates 301 can be cleaned simultaneously, resulting in high anti-clogging efficiency.
[0022] As a technical optimization of this utility model, three discharge ports 302 are provided through the right side of the screening box 3, and the two discharge ports 302 located at the top are respectively located on the upper end face of the two screening plates 301.
[0023] In this embodiment: during the vibrating screening process, the largest particles remain on the top screening plate 301 and are discharged from the corresponding first discharge port 302; medium-sized particles remain on the second screening plate 301 and are discharged from the second discharge port 302; and the finest particles are discharged from the third discharge port 302 at the bottom of the screening box 3.
[0024] As a technical optimization of this utility model, the elastic component 304 is a spring.
[0025] In this embodiment, the spring can effectively transmit the vibration force of the vibrating motor 303 to the entire screening box 3, causing it to generate high-frequency, small-amplitude vibration.
[0026] As a technical optimization of this utility model, the outer wall of the conveying cylinder 1 is connected to the feed hopper 101 and the discharge pipe 104 respectively, and the lower end of the discharge pipe 104 extends into the through groove in the middle of the upper end face of the screening box 3.
[0027] In this embodiment: the feeding hopper 101 facilitates the input of materials, while the discharge pipe 104 can directly and accurately guide the materials processed by the dispersing mechanism into the middle of the screening box 3.
[0028] As a technical optimization of this utility model, a controller is installed on the outer wall of the fixed frame, and the servo motor 103, drive motor 401 and vibration motor 303 are all electrically connected to the controller.
[0029] In this embodiment, the servo motor 103, drive motor 401 and vibration motor 303 can be controlled to work normally by the controller.
[0030] The working principle and usage process of this utility model are as follows: Water-soluble fertilizer granules are fed into the conveying cylinder 1 through the feeding hopper 101. The servo motor 103 drives the spiral conveying plate 102 to convey them to the right. During this process, if the granules are wet, hot water or heat transfer oil can be introduced into the drying outer cylinder 2 through the liquid injection port. The heat is transferred to the material through the wall of the conveying cylinder 1. At the same time, the guide plate 201 changes the flow direction of the heat medium, prolongs the heat exchange time, and achieves preliminary drying and dispersion. Then the material falls into the screening box 3 through the discharge pipe 104. The vibrating motor 303 works, driving the entire screening box 3 to vibrate on the elastic component 304. The two screening plates 301 with different apertures screen the material into three sizes: large, medium and small. The particles of the three sizes are discharged from the three discharge ports 302 respectively. When the screening holes of the screening plate 301 are blocked, the drive motor 401 works, driving the threaded rod 4 to rotate, causing the moving plate 402 and the cleaning steel brush 403 on it to move back and forth along the slide rod, brushing away the particles blocked in the screening holes of the screening plate 301 and preventing blockage.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
