DETAILED DESCRIPTION

[0032] Example one

[0033] The embodiment provides a potato amino acid water-soluble fertilizer fertilizing device with a self-cleaning function, and particularly relates to a specific embodiment of component composition and structural features.

[0034] As Figure 1 and Figure 7 shown, the base 1 serves as the supporting base of the whole fertilizing device and provides a stable placing platform for the device, and a second motor 704 is arranged in the base 1; the motor shaft of the second motor 704 is vertically arranged upwards and is provided with a stirring disc 701 of a stirring mechanism 7; the stirring disc 701 is integrally formed with stirring blades 702 on the side; a plurality of sub plates 703 are symmetrically connected to the two sides of the stirring blades 702; the sub plates 703 are arranged in a high-low mode on the same side; the arrangement heights of two adjacent sub plates 703 are different; the structure increases the stirring intensity and range, so that the water-soluble fertilizer and water are fully and uniformly mixed; the base 1 is provided with a discharge port 101 at the bottom, which is used for discharging the fertilizer-water mixture or the sewage after cleaning.

[0035] As Figure 1As shown, the fertilizer tank 2 is fixed on the base 1 and serves as a container for storing water-soluble fertilizer and water. It has a feeding port 201 on one side of its top and a water inlet 203 on the other side. Both the feeding port 201 and the water inlet 203 are connected to the tank cavity of the fertilizer tank 2, facilitating the separate addition of water-soluble fertilizer and water. The top also features a control panel 202 that controls the transmission mechanism 4 and the water supply mechanism 5. The control panel 202 includes a PCB board with a CPU main control chip, a power supply, and auxiliary control circuitry for centralized control of the various mechanisms. A baffle 3 is located on the top, separating the control panel 202 from the transmission mechanism 4 and the water supply mechanism 5 to prevent water from splashing onto the control panel 202 during cleaning and to protect the internal electronic components. The baffle 3, located on top of the fertilizer tank 2, acts as an isolation barrier, separating the control panel 202 from the transmission mechanism 4 and the water supply mechanism 5, ensuring the dryness and safety of the control panel 202, and improving the reliability and stability of the device.

[0036] like Figure 1 and Figure 3 As shown, the transmission mechanism 4 includes a first motor 401, which is a geared motor. Its motor shaft is interference-fitted with a first pulley 402. The first pulley 402 is rotatably connected to a second pulley 404 via a belt 403. The second pulley 404 is interference-fitted on a splined shaft 407. A ball spline 405 is interference-fitted on the splined shaft 407. The ball spline 405 is coaxially connected to the second pulley 404. The top of the fertilizer tank 2 is also provided with a bearing seat 406, which is rotatably connected to the ball spline 405. The first motor 401 is electrically connected to the control panel 202 via a signal line. The first motor 401 drives the first pulley 402 to rotate, which in turn drives the second pulley 404 to rotate via the belt 403, causing the splined shaft 407 to rotate and extend, providing power to the cleaning mechanism 6.

[0037] like Figure 1 and Figure 4 As shown, the water supply mechanism 5 includes a nozzle 604 connected to a water tank 501. The water tank 501 is also connected to a water pump 503. The inlet of the water pump 503 is connected to the water tank 501 through a water suction pipe 502. The outlet of the water pump 503 is connected to the nozzle 604 through a water supply pipe 504. The part of the water supply pipe 504 located on one side of the cleaning brush plate 602 is fixed by a pipe clamp 607. The water pump 503 is electrically connected to the control panel 202 through a signal line. When the water pump 503 is working, it draws water from the water tank 501 and supplies it to the nozzle 604 through the water supply pipe 504 to spray out, thus cooperating with the cleaning mechanism 6 for cleaning.

[0038] like Figure 1 , Figure 5 and Figure 6As shown, the cleaning mechanism 6 includes a cleaning brush plate 602, with a support arm 603 welded to the top of the cleaning brush plate 602. A bushing 601 is provided at the end of the support arm 603. The support arm 603 is interference-fitted to the end of the splined shaft 407 via the bushing 601. The support arm 603 and the cleaning brush plate 602 form a triangular configuration, making the rotation of the cleaning brush plate 602 more stable. A cleaning roller 605 is rotatably mounted at the front end of the cleaning brush plate 602. The cleaning roller 605 is surrounded by a material covered with hard rubber. The descaling protrusion 606 is attached to the front end of the cleaning brush plate 602 with a waterproof adhesive on its back. The nozzle 604 is fixed to one side of the cleaning brush plate 602 and extends as the spline shaft 407 rotates. The cleaning brush plate 602 rotates and the nozzle 604 sprays water to rinse the inner wall of the fertilizer tank 2. Then the cleaning roller 605 and the descaling protrusion 606 work together to scrape away dirt. The cleaning brush plate 602 cleans the inner wall of the tank from top to bottom in circles to avoid cleaning dead corners.

[0039] like Figure 1 and Figure 7 As shown, the stirring mechanism 7 includes a stirring plate 701, which is driven to rotate by the motor shaft of the second motor 704. The stirring blades 702 on the side of the stirring plate 701 and the multiple undulating auxiliary plates 703 symmetrically connected on both sides of the stirring blades 702 increase the stirring force and range, enabling the water-soluble fertilizer to be fully and evenly mixed with water, and improving the concentration uniformity of the fertilizer-water mixture. The second motor 704 is electrically connected to the control panel 202 through a signal line.

[0040] Example 2

[0041] This embodiment provides a potato amino acid water-soluble fertilizer application device with self-cleaning function. Specifically, it describes the specific implementation method and functional principle of the device.

[0042] like Figures 1 to 7 As shown, the operator first adds potato amino acid water-soluble fertilizer into the cavity of fertilizer tank 2 through the feeding port 201 at the top of fertilizer tank 2. At the same time, an appropriate amount of water is injected into fertilizer tank 2 through the water inlet 203. The feeding port 201 and the water inlet 203 are located on one side of the top of fertilizer tank 2, which facilitates the operator's material addition operation. Both are directly connected to the cavity of fertilizer tank 2 to ensure that the material can enter the tank smoothly.

[0043] After confirming that the equipment is functioning normally, the operator operates the control panel 202 to send a start command to the second motor 704. The second motor 704 is located inside the base 1, with its motor shaft facing upwards and vertically positioned. When the second motor 704 receives the start signal, the motor shaft begins to rotate, driving the mixing disc 701 mounted on it to rotate as well. The mixing disc 701 has an integrally formed mixing blade 702 on its side, and multiple auxiliary plates 703 are symmetrically connected to both sides of the mixing blade 702. The auxiliary plates 703 are arranged at varying heights on the same side, with adjacent auxiliary plates 703 having different heights. This unique structural design increases the mixing force and range. During the rotation of the mixing disc 701, the mixing blade 702 and auxiliary plates 703 continuously agitate the water-soluble fertilizer and water in the fertilizer tank 2, ensuring they come into full contact and mix. As the mixing disc 701 continues to rotate, the water-soluble fertilizer and water gradually mix evenly under the action of the mixing blade 702 and auxiliary plates 703, forming a fertilizer-water mixture of uniform concentration. During this process, the control panel 202 can precisely control the second motor 704 according to the preset stirring time and speed to ensure that the fertilizer-water mixture achieves the ideal mixing effect. Too short a stirring time may lead to uneven mixing, while too long a stirring time will waste energy and time. The precise control of the control panel 202 can effectively avoid these problems. After the fertilizer-water mixture is evenly mixed, the operator operates the control panel 202 again to open the discharge port 101 at the bottom of the base 1. The discharge port 101 is connected to the cavity of the fertilizer tank 2. Under gravity, the fertilizer-water mixture flows out of the fertilizer tank 2 through the discharge port 101 and is supplied to the potato planting area to provide the necessary nutrients for potato growth. During the discharge process, the operator can control the opening degree of the discharge port 101 according to actual needs to adjust the discharge flow rate of the fertilizer-water mixture.

[0044] After fertilization, a large amount of water-soluble fertilizer residue will remain on the inner wall of fertilizer tank 2. To clean this residue, the operator operates the control panel 202 and simultaneously starts the transmission mechanism 4 and the water supply mechanism 5. The first motor 401 of the transmission mechanism 4 is a geared motor. When it receives a start signal, its motor shaft starts to rotate, driving the first pulley 402, which is interference-fitted on it, to rotate as well. The first pulley 402 is rotatably connected to the second pulley 404 via a belt 403, thereby transmitting power to the second pulley 404. The second pulley 404 is interference-fitted on a splined shaft 407, on which a ball spline 405 is interference-fitted. The ball spline 405 is coaxially connected to the second pulley 404. The top of fertilizer tank 2 is also equipped with a bearing seat 406, which is rotatably connected to the ball spline 405. Driven by the second pulley 404, the splined shaft 407 rotates downward and extends under the action of the ball spline 405. Meanwhile, the water pump 503 of the water supply mechanism 5 also starts working. The inlet of the water pump 503 is connected to the water tank 501 through the pumping pipe 502, and the outlet is connected to the nozzle 604 through the supply pipe 504. The water pump 503 draws water from the water tank 501 and delivers it to the nozzle 604 through the supply pipe 504. The part of the supply pipe 504 located on one side of the cleaning plate 602 is fixed by the pipe clamp 607 to ensure the stable connection of the supply pipe 504. The end of the spline shaft 407 is connected to the cleaning mechanism 6. The top of the cleaning plate 602 of the cleaning mechanism 6 is welded with a support arm 603. The end of the support arm 603 is provided with a bushing 601. The support arm 603 is interference-fitted to the end of the spline shaft 407 through the bushing 601, and the support arm 603 and the cleaning plate 602 are in a triangular configuration. This structure makes the cleaning plate 602 more stable during rotation. As the splined shaft 407 extends and rotates, the cleaning brush 602 begins to rotate. At this time, the nozzle 604 is fixed to one side of the cleaning brush 602, and the water jet from the nozzle 604 first rinses the inner wall of the fertilizer tank 2, washing away some loose dirt. Then, the cleaning roller 605 at the front end of the cleaning brush 602 contacts the inner tank wall. Around the cleaning roller 605 are descaling protrusions 606 covered with hard rubber material, and the back of the descaling protrusions 606 is adhered to the front end of the cleaning brush 602 with a waterproof adhesive. With the combined action of the cleaning roller 605 and the descaling protrusions 606, stubborn dirt on the inner tank wall is scraped off. As the splined shaft 407 gradually extends downwards, the cleaning brush 602 cleans the inner tank wall from top to bottom in circular motions, avoiding any blind spots and ensuring a thorough and effective cleaning of the inner wall of the fertilizer tank 2.

[0045] Wastewater generated during the cleaning process is discharged from the fertilizer tank 2 through the discharge port 101 at the bottom of the base 1. During the wastewater discharge process, the operator can observe the wastewater discharged from the discharge port 101 to judge the cleaning effect. If the wastewater still contains a lot of dirt, the control panel 202 can be operated to keep the transmission mechanism 4 and the water supply mechanism 5 working for a period of time until it is clean. After cleaning is completed, the operator operates the control panel 202 to stop the first motor 401 of the transmission mechanism 4, the water pump 503 of the water supply mechanism 5, and the second motor 704 of the stirring mechanism 7 in sequence. After each mechanism stops operating, the device returns to its initial state, ready for the next use.

[0046] In summary, through the detailed introduction of the working process and working principle above, it can be seen that this device can realize the automated operation of fertilization and self-cleaning, with thorough cleaning and uniform mixing. It has a high degree of automation and reasonable structure, which can effectively improve the fertilization quality and growth effect of potatoes.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
