[0019] Working principle: When raising seedlings of crops grown in some greenhouses, the staff first moves and installs the device to the position where it is needed, and then injects the required liquid medicine into each liquid medicine storage chamber in turn through the dosing tube on the liquid medicine barrel. After all the liquid medicine is injected, the height adjustment mechanism is started. First, the staff presses the spring pin on the adjusting rod, so that the spring pin retracts after being pressed, and at the same time, the spring pin on the adjusting rod is released from the limit of the adjusting hole on the adjusting seat at the bottom. After the spring pin is released from the limit fixation of the adjusting hole, the staff adjusts the height of the adjusting rod in the adjusting seat according to the height of the crop seedlings and the spraying situation. While adjusting the height of the adjusting rod, it drives its top The guide rail seat, connecting rod and spraying equipment at the bottom thereof are synchronously raised or lowered. After the movement and adjustment are completed, the spring pin on the adjusting rod is fixed through the adjusting hole at the corresponding height position on the adjusting seat, thereby completing the height adjustment of the entire device; then the moving mechanism is controlled to start, and the staff controls the spraying equipment to conduct a preliminary trial run through the control panel on the side mounting seat. At this time, the staff starts the electric slide rail seat in the track groove through the control panel on the side mounting seat. When the electric slide rail seat is started, it drives the moving seat thereon to move back and forth in a cycle. When the moving seat moves in the track groove on the guide rail seat, it drives the atomizing spray row at the bottom thereof and the root spray rod at the side to move synchronously, thereby completing the movement control processing of the entire device;At the same time, the mixing mechanism is adjusted to start. Before the overall device is used, the staff will inject agricultural liquid with different functions into each liquid storage chamber in the liquid barrel through the dosing pipe on the liquid barrel. When the liquid in the liquid barrel is discharged, the delivery pump on the side mounting seat is started to pump the liquid in the liquid barrel, and the liquid in the liquid storage chamber at the bottom inside the liquid barrel is transported to the spraying equipment through the liquid outlet pipe and the connecting pipe for spraying. When the staff needs to adjust the sprayed liquid, the staff starts the stepper motor through the control panel on the side mounting seat. When the stepper motor is started, its rotating shaft drives the rotating seat in the liquid barrel to rotate, and the rotating seat When the movable seat rotates, it drives the side plates in the inner cavity to rotate synchronously. When the side plates rotate, it also drives the center column between them to rotate synchronously. When the center column rotates, it drives the partition plates and rubber sealing strips thereon to rotate synchronously in the inner cavity. When the partition plates rotate, the liquid in each liquid storage cavity is also adjusted synchronously in the inner cavity. When the pesticide liquid needed by the staff rotates to the bottom of the inner cavity and the position of the liquid outlet pipe, the stepper motor on the side mounting seat stops operating, and then the staff uses the delivery pump on the side mounting seat to pump the liquid to the position of the spraying equipment to complete the spraying treatment during the crop seedling cultivation process. When the motor drives the rotating seat in the medicine liquid barrel, the rotating seat rotates and drives the medicine liquid storage chambers at various positions between the side plates to rotate synchronously in the inner cavity. While the medicine liquid in the medicine liquid storage chamber is driven to rotate by the partition plate, the medicine liquid in the medicine liquid storage chamber is also driven to shake synchronously, thereby preventing the medicine liquid in the medicine liquid storage chamber from settling for a long time and causing precipitation, and also preventing the medicine liquid from having poor uniformity and affecting its subsequent use effect; at the same time, the spraying adjustment mechanism is started, and when it is used for some crop seedlings that require top spraying, the medicine liquid delivered by the delivery pump on the side mounting seat enters the liquid dispensing seat on the moving seat, and then is controlled by the liquid dispensing seat The liquid is then diverted to the atomizing spray row at the bottom of the mobile seat, and then atomized and sprayed onto the seedlings of crops through the atomizing spray row. When used for some seedlings of crops that need root spraying, the liquid delivered by the delivery pump on the side mounting seat enters the liquid separation seat on the mobile seat, and then the three-way solenoid valve on the liquid separation seat is started, so that the liquid in the liquid separation seat enters the liquid separation pipe on the side of the mobile seat through the connecting pipe, and then the liquid in the liquid separation pipe is diverted to the root spray rods at various positions, and finally the liquid is sprayed to the root position of the crops through the spray nozzle on the root spray rod, thereby completing the adjustment of the spraying position. ;

[0020] The present invention provides an adjustable spraying device for agricultural seedling cultivation, which has the following beneficial effects:

[0021] 1. The present invention increases and sets a height adjustment mechanism. When spraying pesticides on crop seedlings, on the one hand, the overall device can be adapted to the heights of different types of crop seedlings for spraying pesticides, and has strong adaptability. On the other hand, the height of the overall device can be adjusted to reduce the degree of spillage of the pesticide liquid during the spraying process, thereby reducing the waste of the pesticide liquid and improving the absorption of the pesticide liquid by the crops.

[0022] 2. The present invention optimizes the spraying process of crop seedlings by adding and setting a control mobile mechanism. The mobile mechanism not only improves the operational flexibility of the spraying equipment, but also allows the staff to monitor and adjust the operating status of the spraying equipment in real time. This design significantly improves the accuracy and efficiency of the spraying process, ensuring that the agent is evenly covered on the seedlings, thereby enhancing the efficacy of the agent and reducing the waste of the agent. The real-time monitoring and control function enables the operator to promptly discover and solve potential problems, thereby improving work safety and the service life of the equipment.

[0023] 3. The present invention adds and sets an adjusting and mixing mechanism. When spraying crop seedlings, the mechanism can, on the one hand, adjust and replace the corresponding type of pesticide solution according to the needs of the staff and the type of crops, thereby improving the targeted use of pesticides and reducing the cost and waste of pesticides during use. On the other hand, it can also prevent the solution from precipitating or stratifying during storage, thereby ensuring the normal efficacy of the pesticide solution and preventing the precipitate from clogging the spraying equipment. At the same time, the overall device has a high degree of continuity during use and also reduces the labor intensity of the staff.

[0024] 4. The present invention achieves significant optimization in the crop spraying process by adding and setting a spraying adjustment mechanism. The mechanism can automatically adjust the height of the spray according to the different heights of crop seedlings, thereby ensuring that both short and tall crops can be evenly covered with the pesticide. In addition, the spraying adjustment mechanism also supports switching between top spraying and root spraying modes. This function not only improves the flexibility and accuracy of spraying, but also can select the most suitable spraying method according to different crop needs and growth stages, further enhancing the effect of the pesticide and reducing resource waste.

[0036] A height adjustment mechanism is provided on both sides of the top of the base 1 and is used to adjust the spraying height of the entire device;

[0037] The height adjustment mechanism includes an adjustment seat 9, and the middle parts of both sides of the top of the base 1 are fixedly connected with the adjustment seat 9, and the middle part of the outer wall of the adjustment seat 9 is evenly spaced with a plurality of adjustment holes 8, and the inner middle part of the adjustment seat 9 is slidably connected with an adjustment rod 2, and the top end of the adjustment rod 2 penetrates the adjustment seat 9 and extends upward, and a spring pin rod 7 is provided in the middle and lower part of one side of the outer wall of the adjustment rod 2, and one end of the spring pin rod 7 penetrates the corresponding adjustment hole 8 and extends outward, and the top end of the adjustment rod 2 on the same side is respectively connected to the middle parts of both sides of the bottom end of the guide rail seat 10.

[0038] When the height adjustment mechanism is started, the staff first presses the spring pin rod 7 on the adjusting rod 2, so that the spring pin rod 7 retracts after being pressed, and at the same time, the spring pin rod 7 on the adjusting rod 2 is released from the limit of the adjusting hole 8 on the adjusting seat 9 at its bottom. After the limit fixation of the spring pin rod 7 on the adjusting hole 8 is released, the staff adjusts the height of the adjusting rod 2 in the adjusting seat 9 according to the height of the crop seedlings and the spraying situation. While the height of the adjusting rod 2 is adjusted, it drives the guide seat 10, the connecting rod 6 and the spraying equipment at its bottom to rise or fall synchronously. After the movement and adjustment are completed, the spring pin rod 7 on the adjusting rod 2 is fixed through the adjusting hole 8 at the corresponding height position on the adjusting seat 9, thereby completing the height adjustment of the entire device.

At this time, the staff starts the electric slide rail seat 18 in the track groove 17 through the control panel 21 on the side mounting seat 3. When the electric slide rail seat 18 is started, it drives the moving seat 5 thereon to move back and forth in a cycle. When the moving seat 5 moves in the track groove 17 on the guide rail seat 10, it drives the atomizing spray row 4 at the bottom and the root spray rod 11 on the side to move synchronously, thereby completing the movement control processing of the entire device.

[0042] The regulating and mixing mechanism is arranged in the side mounting seat 3 and is used for output regulation and mixing of the liquid medicine used in the agricultural seedling raising process to prevent precipitation;

[0043] The regulating and mixing mechanism includes a medicine liquid barrel 12, which is arranged on the middle and upper part of the inner side of the side mounting seat 3, and support seats 14 are fixedly connected to both sides of the bottom end of the inner side of the side mounting seat 3, and the top ends of the support seats 14 are respectively connected to the corresponding positions of the bottom end of the medicine liquid barrel 12, and an inner cavity 32 is arranged on the inner side of the medicine liquid barrel 12, and a dosing tube 13 is arranged on one side of the middle part of the top end of the medicine liquid barrel 12, and the interior of the dosing tube 13 is connected to the interior of the inner cavity 32, and a sealing cover is threadedly connected to the top of the dosing tube 13.

[0044] When the adjusting and mixing mechanism is started, before the overall device is used, the staff will inject agricultural liquid with different functions into each liquid storage cavity 27 in the liquid barrel 12 through the dosing pipe 13 on the liquid barrel 12. When the liquid in the liquid barrel 12 is discharged, the delivery pump 15 on the side mounting seat 3 is started to pump the liquid in the liquid barrel 12. The liquid in the liquid storage cavity 27 at the bottom of the inner side of the liquid barrel 12 is delivered to the spraying equipment for spraying through the liquid outlet pipe 23 and the connecting pipe.

[0045] The regulating and mixing mechanism also includes a center column 29, which is arranged in the middle of the inner side of the inner cavity 32, and both ends of the center column 29 are fixedly connected to side panels 31, and the middle of the outer side of the side panels 31 are fixedly connected to the rotating seat 28.
