[0029] Reference Figure 1As shown, the utility model provides a technical solution: an automatic driving device for a self-propelled sprayer, comprising a body 1, a cartridge 2 is installed on the surface of the body 1, a drive box 3 is installed on the lower surface of the body 1, a signal receiver 4 is electrically connected to one side of the drive box 3, a spray arm 5 is installed on both sides of the body 1, the cartridge 2 is connected to the spray arm 5, a plurality of brackets 6 are installed on the lower surface of the body 1, a tire 7 is installed on the inner wall of the bracket 6, and a loosening structure 8 is provided on the surface of the body 1. By providing the loosening structure 8, it is convenient to loosen the soil rolled by the self-propelled sprayer, so as to avoid the situation that the air permeability and drainage of the soil are reduced after the soil is compacted, and the soil texture is deteriorated, thereby improving the root growth and water absorption of plants. A cleaning structure 9 is provided on the surface of the bracket 6. By providing the cleaning structure 9, it is convenient to scrape off the soil attached to the surface of the tire 7. Cleaning the tire 7 can also extend the service life of the tire 7 and reduce the damage caused by the wear of the tire 7 by the soil and debris.
[0030] The specific settings and functions of the soil loosening structure 8 and the cleaning structure 9 will be described in detail below.
[0031] Reference Figure 2 and Figure 3 and Figure 4 As shown, in this embodiment: the loosening structure 8 includes two fixing plates 81, both fixing plates 81 are fixedly connected to one side of the machine body 1, the surface of the fixing plate 81 is threaded with a threaded rod 82, the end of the threaded rod 82 close to the ground is rotatably connected to a driving plate 83, and the side of the driving plate 83 close to the ground is fixedly connected to a plurality of spikes 84. The surfaces of the plurality of spikes 84 are slidably connected with a scraper 85, and the surface of the scraper 85 is fixedly connected with a plurality of rubber rings 87, the size of the rubber ring 87 is adapted to the size of the spike 84, and bolts 86 are threadedly connected on both sides of the scraper 85, and the scraper 85 will drive the rubber ring 87 to slide along the surface of the spike 84, and the movement of the rubber ring 87 will scrape off the soil attached to the surface of the spike 84, thereby preventing the soil from being attached to the surface of the spike 84 and solidifying on the surface and being difficult to remove. The surface of the fixed plate 81 is slidably penetrated by a round rod 88, and the round rod 88 is fixedly connected to the surface of the driving plate 83. When the driving plate 83 moves, it drives the round rod 88 to slide in the fixed plate 81, and the fixed plate 81 limits the moving path of the round rod 88, and then limits the moving path of the driving plate 83, thereby preventing the driving plate 83 from rotating when moving. The end of the threaded rod 82 away from the driving plate 83 is fixedly connected to a rotating disk 89, and the cross section of the rotating disk 89 is in a "cross" shape. The rotation of the rotating disk 89 drives the threaded rod 82 to rotate, and the rotating disk 89 facilitates the rotation of the threaded rod 82.
[0032] Reference Figure 5As shown, specifically, the cleaning structure 9 includes a support arm 91, the support arm 91 is fixedly connected to the surface of the bracket 6, the inner wall of the support arm 91 is slidably connected with an adjustment arm 92, the surface of the support arm 91 is slidably inserted with a latch 93, the surface of the adjustment arm 92 is provided with two circular grooves 94, the size of the latch 93 is adapted to the size of the circular groove 94, and a triangular block 95 is fixedly connected to the side of the adjustment arm 92 close to the tire 7. A limiting groove 96 is provided on one side of the adjustment arm 92, and a limiting block 97 is slidably connected to the inner wall of the limiting groove 96, and the limiting block 97 is fixedly connected to one side of the support arm 91. The movement of the adjustment arm 92 causes the limiting block 97 to slide in the limiting groove 96, and the limiting block 97 reaches the effect of limiting the moving path of the adjustment arm 92, thereby preventing the adjustment arm 92 from falling out of the support arm 91. The arc surface of the latch 93 is covered with a spring 98, and the two ends of the spring 98 are fixedly connected to the latch 93 and the support arm 91 respectively. The latch 93 will be inserted into the circular groove 94 with the help of the contraction force of the spring 98. The spring 98 can improve the stability of the latch 93 inserted into the circular groove 94 and prevent the latch 93 from falling out of the circular groove 94 due to shaking.
[0033] Working principle: when using the self-propelled sprayer to spray crops, first rotate the turntable 89. The rotation of the turntable 89 will drive the threaded rod 82 to rotate. The rotation of the threaded rod 82 will move in the fixed plate 81 with the help of the thread. The movement of the threaded rod 82 will drive the driving plate 83 to move in the direction close to the ground. When the driving plate 83 moves, it will drive the round rod 88 to slide in the fixed plate 81. The fixed plate 81 reaches the limit of the moving path of the round rod 88, and then limits the moving path of the driving plate 83, thereby preventing the driving plate 83 from rotating when moving. After the driving plate 83 moves to a suitable position, it will drive the spikes 84 to insert into the crushed soil, and then the self-propelled sprayer will drive the spikes 84 to move in the soil when moving, thereby loosening the compacted soil. When the self-propelled sprayer drives out of the farmland, it rotates in the opposite direction. The turntable 89 and the threaded rod 82 rotate with the help of the turntable 89 to drive the driving plate 83 to move, and the driving plate 83 drives the spike 84 to move away from the ground. When the spike 84 moves to a suitable position, the two bolts 86 are rotated, and the bolts 86 move away from the driving plate 83 with the help of the threads. When the bolts 86 are out of contact with the driving plate 83, the scraper 85 is pulled, and the scraper 85 drives the rubber ring 87 to slide along the surface of the spike 84. The movement of the rubber ring 87 will scrape off the soil attached to the surface of the spike 84, thereby preventing the soil from adhering to the surface of the spike 84 and solidifying on the surface and being difficult to remove. After the soil attached to the surface of the spike 84 is removed, the scraper 85 is reset, and then the bolts 86 are rotated in the opposite direction until the bolts 86 abut against the surface of the driving plate 83, thereby limiting the position of the scraper 85.
[0034] When the self-propelled sprayer is needed to spray crops, the latch 93 is first pulled. The latch 93 moves and slides in the support arm 91 and gradually comes out of the circular groove 94. The latch 93 gradually stretches the spring 98 when it moves. When the latch 93 comes out of the circular groove 94, the spring 98 is in a stretched state, pushing the adjustment arm 92. The movement of the adjustment arm 92 causes the limit block 97 to slide in the limit groove 96. The limit block 97 reaches the limit of the moving path of the adjustment arm 92, thereby preventing the adjustment arm 92 from coming out of the support arm 91. The movement of the adjusting arm 92 will drive the triangular block 95 to move, and the triangular block 95 will move toward the direction close to the tire 7. After the triangular block 95 moves to a suitable position, the latch 93 is released, and the latch 93 is inserted into the circular groove 94 with the help of the contraction force of the spring 98. The latch 93 reaches the position of limiting the adjusting arm 92, thereby limiting the position of the triangular block 95. At this time, the self-propelled sprayer will make the tire 7 rotate in the bracket 6 when moving, and the rotation of the tire 7 will make the triangular block 95 slide on the surface of the tire 7, thereby scraping off the mud attached to the surface of the tire 7.
