Description

Technical Field

[0001] This invention relates to the field of garden maintenance technology, and in particular to a self-propelled garden plant protection spraying device. Background Technology

[0002] Garden maintenance refers to the routine upkeep, repair, prevention and repair of catastrophic damage to ensure the normal use of gardens, as well as measures such as reinforcement, improvement, or expansion to enhance the quality of use, aesthetic appeal, and service levels. During garden maintenance, workers use sprayers to spray pesticides on green plants to prevent pests and diseases; this spraying is essentially artificial fogging. Simply put, a high-pressure system sprays liquid into extremely fine water particles. These tiny artificial fog particles can drift and remain suspended in the air for a long time, creating a white, misty spectacle that closely resembles the effect of natural fog, hence the name "spraying."

[0003] Existing self-propelled garden plant protection spraying devices typically involve moving the spraying mechanism through a mobile device. However, during spraying, the complex environment of garden paths, including protruding tree branches, can easily cause the spraying mechanism to collide and scrape against these branches, resulting in damage. Furthermore, over time, the atomizing nozzles can become clogged by impurities in the pesticide solution, requiring special cleaning equipment for unclogging, which is time-consuming, labor-intensive, and inconvenient for users. Summary of the Invention

In the process of using existing self-propelled garden plant protection spraying devices, the spraying mechanism is generally moved and sprayed in the garden by a mobile device. However, during the spraying process, due to the complex environment of the garden road, there are protruding dead branches. When the mobile device is driven to move the spraying mechanism, the spraying mechanism is prone to collision and scratching with the protruding dead branches, resulting in damage to the spraying mechanism. At the same time, during long-term use, the atomizing nozzle is easily clogged by impurities in the liquid, requiring special cleaning and unblocking mechanisms, which is time-consuming and labor-intensive.

Beneficial effects

[0015] Considering that existing self-propelled garden plant protection spraying devices are generally moved around the garden by a mobile device, the complex environment of the garden road, including protruding dead branches, can easily cause the spraying device to collide and scrape with the protruding dead branches when the mobile device is driven to move the spraying device, resulting in damage to the spraying device. At the same time, during long-term use, the atomizing nozzles are easily clogged by impurities in the liquid, requiring special cleaning and unblocking, which is time-consuming and labor-intensive.

[0016] 1. In use, this invention stores and mixes the required spray solution through a storage mechanism. Before spraying, the spray solution is first poured into the pretreatment tank through the feed hopper. Then, the first drive motor is turned on, causing the rotating rod to drive the stirring rod to rotate inside the pretreatment tank, thereby mixing the solution inside the pretreatment tank and preparing it for spraying. After the solution inside the pretreatment tank is mixed, the pump is turned on, causing the pumping pipe to draw the mixed solution from the pretreatment tank to the drain pipe. The solution is then poured into the infusion tank through the drain pipe for storage. During spraying, the solution is drawn from the infusion tank for spraying. This storage mechanism allows for continuous pretreatment of the solution through the pretreatment tank while the solution is being transported in the infusion tank, achieving uninterrupted mixing and transfer of the solution.

[0017] 2. In this invention, when performing pesticide spraying operations in gardens, the spraying mechanism is adjusted to perform the spraying operation. By turning on the water pump, the water pump draws the pesticide solution from the infusion tank into the drain pipe, and then the drain pipe guides the solution into the water guide pipe, finally flowing into the water pipe. The solution is then atomized and sprayed out through an atomizing nozzle installed at one end of the water pipe, thus completing the spraying operation. During the spraying operation, when it is necessary to adjust the spray length, the motor is turned on, causing the drive rod to rotate, which in turn drives a driven gear to rotate, thereby rotating the adjusting rod. When the adjusting rod rotates... This mechanism rotates the top adjustment frame and spray frame, allowing for adjustment of the spray frame and atomizing nozzle. This facilitates adjustment of the atomizing spray length. The two sets of adjustment frames at both ends are driven by independent motors, enabling independent adjustment of the two spray frames to accommodate different spray lengths on each side. Furthermore, during spraying operations in the garden, if the spray frame encounters vegetation obstacles while advancing, obstacle avoidance sensors are installed at one end of each set of spray frames. These sensors are infrared obstacle avoidance devices, emitting infrared rays of a specific frequency through an infrared emitter, and the receiver detects the reflected signal. When an obstacle is encountered, the reflected signal is received and converted into an electrical signal. The detection distance can be adjusted by a potentiometer. When the obstacle avoidance sensor detects a tree protruding from the garden in front of the spray frame, a hydraulic cylinder is driven by a relay or MOSFET. This causes the hydraulic cylinder to move the sliding block and the spray frame up and down along the limit groove according to the height of the obstacle, thereby preventing the spray frame from scratching or colliding with the tree protruding from the garden. At the same time, the servo motor rotates in coordination with the raising and lowering of the spray frame, thereby extending and retracting the water pipe.

[0018] 3. During spraying operations, this invention prevents clogging of the atomizing nozzles through an anti-clogging mechanism. The water inlet pipe is connected to the water outlet pipe. During spraying, the liquid medicine in the water outlet pipe passes through the water inlet pipe and the anti-clogging pipe, and is finally sprayed out through the atomizing nozzles. As the liquid medicine passes through the anti-clogging pipe, it enters the water guide channel at one end of the diversion pipe through the inlet. Through the special flow channel of the water guide channel, it flows towards the resistance plate on the driven fan side, causing the driven fan to rotate under the influence of the resistance plate and the liquid medicine flow. The rotation of the driven fan also drives the collection box to rotate synchronously. During the rotation of the collection box, the scraper at the bottom of the collection box... The plate scrapes off impurities and dirt adhering to the filter plate. As the collection box continues to rotate, the dirt and impurities are carried into the collection chamber inside the collection box for collection. As the collection box continues to rotate, the dirt and impurities remain in the collection chamber under the action of centrifugal force, thus preventing the filter holes on the filter plate from becoming clogged and preventing impurities and dirt from entering the atomizing nozzle and causing clogging. This increases the service life of the filter plate. When it is necessary to clean the impurities inside the collection chamber, the anti-clogging tube can be removed and the handle can be pulled to take out the diverter tube and the filter plate, thereby cleaning the inside of the collection chamber.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] This invention provides, for example Figure 1-13The self-propelled garden plant protection spraying device shown includes a frame body 1, with casters 2 mounted on the bottom of the frame body 1, a cab 3 mounted on the front of the frame body 1, a headlight 4 mounted on the front of the cab 3, a crash bar 5 mounted on the bottom of the headlight 4, a mounting plate 6 fixed to the top of the frame body 1, a storage mechanism 7 provided on the top of the frame body 1, a spray adjustment mechanism 8 provided on the top of the mounting plate 6, an adjustment frame 804 mounted on the top of the mounting plate 6, a servo motor 811 mounted on the top of the adjustment frame 804, a winding rod 812 mounted on the bottom of the servo motor 811, a water guide pipe 813 wound around the outer wall of the winding rod 812, one end of the water guide pipe 813 connected to a water pipe 814, and a limit groove 8 on one side of the adjustment frame 804. 19. A movable slider 816 is provided inside the limiting slide groove 819. A driving hydraulic cylinder 817 is installed at the top of the movable slider 816. A spray frame 815 is installed at one end of the movable slider 816. An obstacle avoidance sensor 818 is installed at one end of the spray frame 815. An anti-clogging mechanism 9 is connected to one end of the water pipe 814. A water receiving pipe 901 is connected to one side of the water pipe 814. An anti-clogging pipe 902 is threaded to one end of the water receiving pipe 901. A diversion pipe 907 is installed inside the anti-clogging pipe 902. A water guide groove 909 is opened at one end of the diversion pipe 907. A filter plate 910 is installed at one end of the diversion pipe 907. A collection box 914 is installed at one end of the filter plate 910. A scraper 916 is installed at the bottom of the collection box 914. When the present invention is in use, when spraying... Before misting operations, the pesticide solution to be sprayed is first poured into the pretreatment tank 702 through the feed hopper 703. Then, the first drive motor 704 is turned on, causing the rotating rod 705 to drive the stirring rod 706 to rotate inside the pretreatment tank 702, thus mixing the pesticide solution inside the pretreatment tank 702 in preparation for spraying. After the pesticide solution inside the pretreatment tank 702 is mixed, the liquid pump 707 is turned on, causing the liquid pumping pipe 708 to draw the mixed pesticide solution from the pretreatment tank 702 to the drain pipe 709. The pesticide solution is then poured into the infusion tank 710 for storage. During the spraying operation, the pesticide solution in the infusion tank 710 is drawn out for spraying. During the delivery of the medicine solution from the infusion tank 710, the storage mechanism 7 can further pre-treat the medicine solution through the pre-treatment tank 702, achieving uninterrupted mixing and transfer of the medicine solution. During spraying operations, by turning on the water pump 801, the water pump 802 draws the medicine solution from the infusion tank 710 into the drain pipe 803, which then guides the medicine solution into the guide pipe 813, finally flowing into the water pipe 814. The solution is then atomized and sprayed through the atomizing nozzle 903 installed at one end of the water pipe 814, thus completing the spraying operation. During spraying operations, when it is necessary to adjust the spray length, the motor 805 can be turned on, causing the drive rod 806 to rotate the transmission gear 807. While the transmission gear 807 is rotating...The driven gear 808, which is engaged at one end, will rotate, thereby causing the adjusting rod 809 to rotate. When the adjusting rod 809 rotates, it will drive the adjusting frame 804 and the spray frame 815 at the top to rotate, thereby causing the spray frame 815 and the atomizing nozzle 903 to rotate and adjust, thus facilitating the adjustment of the atomizing spray length of the atomizing nozzle 903. The two sets of adjusting frames 804 at both ends are driven by independent motors 805, so that the two sets of spray frames 815 can be adjusted independently, which is convenient for independent adjustment when different spray lengths are required on both sides. At the same time, when spraying in the garden, if the spray frame 815 encounters grass or trees as it is spraying forward, an obstacle avoidance sensor 818 is installed at one end of each set of spray frames 815. The obstacle avoidance sensor 818 is an infrared obstacle avoider, which emits infrared rays of a specific frequency by an infrared emitting tube and detects the reflected signal by a receiving tube. When an obstacle is encountered, the reflected signal is received and converted into an electrical signal. The detection distance can be adjusted via a potentiometer. When the obstacle avoidance sensor 818 detects a tree extending from the garden in front of the spray frame 815, it drives the hydraulic cylinder 817 via a relay or MOSFET. This causes the hydraulic cylinder 817 to move the sliding slider 816 and the spray frame 815 up and down along the limit groove 819 according to the height of the obstacle, thereby preventing the spray frame 815 from scraping or colliding with the tree extending from the garden. Simultaneously, a servo... The motor 811 rotates in coordination with the lifting and lowering of the spray frame 815, thereby extending and retracting the water guide pipe 813. The water inlet pipe 901 is connected to the water outlet pipe 814. During spraying operations, the liquid medicine in the water outlet pipe 814 passes through the water inlet pipe 901 and the anti-clogging pipe 902, and is finally sprayed out through the atomizing nozzle 903. When the liquid medicine passes through the anti-clogging pipe 902, it enters the water guide groove 909 at one end of the diversion pipe 907 through the water inlet 906. Through the special flow channel of the water guide groove 909, it flows towards the driven fan 912. The resistance plate 913 causes the driven fan 912 to rotate under the influence of the resistance plate 913 and the flow of the liquid medicine. As the driven fan 912 rotates, it also drives the collection box 914 to rotate synchronously. During the rotation of the collection box 914, the scraper 916 at the bottom of the collection box 914 scrapes off the impurities and dirt adhering to the filter plate 910. With the continued rotation of the collection box 914, the impurities and dirt are carried to the collection chamber 915 inside the collection box 914 for collection. The collection box 914 continues to rotate... During operation, under the action of centrifugal force, dirt and impurities will remain in the collection chamber 915, thus preventing clogging of the filter holes on the filter plate 910 and preventing impurities and dirt from entering the atomizing nozzle 903 and causing clogging. This increases the service life of the filter plate 910. When it is necessary to clean the impurities inside the collection chamber 915, the diversion pipe 907 and filter plate 910 can be removed by disassembling the anti-clogging tube 902 and pulling the handle 908, thereby cleaning the inside of the collection chamber 915.

[0042] In this solution, during spraying operations, the required pesticide solution is stored and mixed via a storage mechanism 7. The storage mechanism 7 includes a support plate 701 mounted on the top of the vehicle frame body 1. A pretreatment tank 702 is mounted on the top of the support plate 701, and a feed hopper 703 is mounted on the top of the pretreatment tank 702. A first drive motor 704 is mounted on one end of the pretreatment tank 702, and a rotating rod 705 is mounted on one end of the first drive motor 704. A stirring rod 706 is mounted on the outer wall of the rotating rod 705. A liquid extraction pump 707 is mounted on the top of the vehicle frame body 1, with a liquid extraction pipe 708 mounted on one end of the pump 707 and a drain pipe 709 mounted on the end of the pump 707 away from the liquid extraction pipe 708. An infusion tank 710 is mounted on the end of the vehicle frame body 1 away from the pretreatment tank 702, with a second drive motor 711 mounted on one end of the infusion tank 710. A stirring shaft 712 is installed inside the infusion tank 710. Before spraying operations... First, the liquid medicine to be sprayed is poured into the pretreatment tank 702 through the feed hopper 703. Then, by turning on the first drive motor 704, the rotating rod 705 drives the stirring rod 706 to rotate inside the pretreatment tank 702, thereby mixing the liquid medicine inside the pretreatment tank 702 and preparing it for spraying. After the liquid medicine inside the pretreatment tank 702 is mixed, the liquid pump 707 is turned on, and the liquid pumping pipe 708 draws the mixed liquid medicine inside the pretreatment tank 702 into the drain pipe 709. The liquid medicine is then poured into the infusion tank 710 through the drain pipe 709, where it is stored. During the spraying operation, the liquid medicine inside the infusion tank 710 is drawn out for spraying. This storage mechanism 7 can continue to pre-treat the liquid medicine through the pretreatment tank 702 while the liquid medicine is being transported through the infusion tank 710, thus completing the uninterrupted mixing and transmission of the liquid medicine.

[0043] In this solution, when performing pesticide spraying operations on gardens, the spraying operation is carried out by adjusting the spraying mechanism 8. The spraying mechanism 8 includes a water pump 801 installed at the top of the liquid pump 707. A water pump pipe 802 is installed at one end of the water pump 801, and a drain pipe 803 is installed at the end of the water pump 801 away from the water pump pipe 802. An electric motor 805 is installed inside the frame body 1. A drive rod 806 is installed at one end of the electric motor 805, and a transmission gear 807 is installed at one end of the drive rod 806. A driven gear is meshed at one end of the transmission gear 807. 808, an adjusting rod 809 is installed inside the driven gear 808, a through groove 810 is opened on one side of the adjusting frame 804, and a limit baffle 820 is provided on one side of the spray frame 815. When the water pump 801 is turned on, the water pumping pipe 802 draws the medicine solution inside the infusion tank 710 into the drain pipe 803, and then the drain pipe 803 guides the medicine solution into the guide pipe 813, finally flowing into the water pipe 814. The solution is then atomized and sprayed out through the atomizing nozzle 903 installed at one end of the water pipe 814, thus completing the spraying operation. During operation, when the spray length needs to be adjusted, the motor 805 can be turned on, causing the drive rod 806 to rotate the transmission gear 807. When the transmission gear 807 rotates, it drives the driven gear 808, which is engaged at one end, to rotate. This causes the adjusting rod 809 to rotate, which in turn drives the adjusting bracket 804 and the spray bracket 815 at the top to rotate. This allows the spray bracket 815 and the atomizing nozzle 903 to be adjusted, thus facilitating the adjustment of the atomization spray length of the atomizing nozzle 903. The two sets of adjustment brackets 804 at both ends are driven by independent motors 805, which allows the two sets of spray brackets 815 to be adjusted independently. This facilitates independent adjustment when different spray lengths are required on both sides. At the same time, when spraying in the garden, if the spray brackets 815 encounter grass or tree obstacles in front of them while spraying forward, obstacle avoidance sensors 818 are installed at one end of both sets of spray brackets 815. The obstacle avoidance sensor 818 is an infrared obstacle avoider, which emits infrared rays of a specific frequency by an infrared emitting tube and detects the reflected signal by a receiving tube. When an obstacle is encountered, the reflected signal is received and converted into an electrical signal. The detection distance can be adjusted by a potentiometer. When the obstacle avoidance sensor 818 senses that there are trees extending from the garden in front of the spray frame 815, the hydraulic cylinder 817 is driven by a relay or MOSFET. The hydraulic cylinder 817 drives the moving slider 816 and the spray frame 815 to move up and down along the limit slide groove 819 according to the height of the obstacle, thereby avoiding the spray frame 815 from scratching and colliding with the trees extending from the garden. At the same time, the servo motor 811 will rotate in coordination with the raising and lowering of the spray frame 815, thereby extending and retracting the water pipe 813.

[0044] During spraying operations, this solution prevents the atomizing nozzle 903 from clogging using an anti-clogging mechanism 9. The anti-clogging mechanism 9 includes an atomizing nozzle 903 installed at one end of an anti-clogging pipe 902. One end of the anti-clogging pipe 902 is equipped with a threaded cap 904. The inner wall of the water inlet pipe 901 is provided with a threaded sleeve 905. An inlet 906 is provided at the end of the anti-clogging pipe 902 near the water inlet pipe 901. A handle 908 is installed at one end of a diversion pipe 907. A limit block 911 is installed on the inner wall of the anti-clogging pipe 902. One end of the filter plate 910 is connected to a mounting bearing 91. 7. The collection box 914 has a collection chamber 915 inside. A driven fan 912 is installed at one end of the collection box 914, and a baffle plate 913 is installed on one side of the driven fan 912. The water inlet pipe 901 is connected to the water outlet pipe 814. During spraying, the liquid medicine in the water outlet pipe 814 passes through the water inlet pipe 901 and the anti-clogging pipe 902, and is finally sprayed out through the atomizing nozzle 903. When the liquid medicine passes through the anti-clogging pipe 902, it enters the water guide groove 909 at one end of the diversion pipe 907 through the water inlet 906. The special flow channel directs the liquid towards the resistance plate 913 on one side of the driven fan 912, causing the driven fan 912 to rotate under the influence of the resistance plate 913 and the flow of the liquid. As the driven fan 912 rotates, it also drives the collection box 914 to rotate synchronously. During this rotation, the scraper 916 at the bottom of the collection box 914 scrapes off impurities and dirt adhering to the filter plate 910. With the continued rotation of the collection box 914, these impurities and dirt are carried to the collection chamber 915 inside the collection box 914 for collection. As the collection box 914 rotates continuously, the dirt and impurities remain in the collection chamber 915 under the action of centrifugal force. This prevents the filter holes on the filter plate 910 from becoming clogged and also prevents impurities and dirt from entering the atomizing nozzle 903 and causing it to become clogged. This increases the service life of the filter plate 910. When it is necessary to clean the impurities inside the collection chamber 915, the diversion pipe 907 and the filter plate 910 can be removed by removing the anti-clogging tube 902 and pulling the handle 908, thereby cleaning the inside of the collection chamber 915.
