DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: an agricultural spraying device, including a unicycle 1, on which a medicine storage tank 102 is fixedly connected. At the front end of the unicycle 1, support disks 2 are symmetrically and fixedly connected. On the front surface of the support disk 2, a rotating shaft 202 is rotatably installed. At the other end of the rotating shaft 202, a sleeve 203 is fixedly connected. A spray pipe 4 is sleeved on the sleeve 203. Below the spray pipe 4, a number of spray nozzles 401 are connected. A limiting block 3 is fixedly connected to the rotating shaft 202.

[0022] In this implementation scheme, with the unicycle 1 as the carrier, the unicycle is convenient to move in ridges and ditches in the field. Thus, while not rolling over crops, the device can move in the field. Using two spray pipes 4, the liquid medicine in the medicine storage tank 102 is transported to the inside of the spray pipe 4. The spray nozzles 401 will spray the liquid medicine onto the crops on both sides of the unicycle 1. The spray pipe 4 is supported and installed at the front end of the unicycle 1 by the sleeve 203. The limiting hole 201 rotates and is connected to the support disk 2. Thus, rotating the rotating shaft 202 can drive the spray pipe 4 to rotate, making the spray pipe 4 in a vertical state, which can avoid interference between the unfolded spray pipe 4 and reeds, trees, etc. on both sides during the process of moving and adding medicine to the unicycle 1, affecting the movement of the device in the field.

[0023] Among them, in order to achieve the purpose of pumping the liquid medicine to the spray pipe 4, the present device is implemented by the following technical scheme: on the unicycle 1 and behind the medicine storage tank 102, a controller 101 is fixedly connected. Inside the controller 101, a control module and a storage battery are fixedly connected. Inside the medicine storage tank 102, a pump is fixedly connected. The conveying end of the pump is fixedly connected with a distribution hose 103. The other two ends of the distribution hose 103 are both fixedly connected with a first threaded connector 104. One end of the spray pipe 4 is fixedly connected with a second quick connector 402, and the second quick connector 402 is in threaded fit with the first threaded connector 104.

[0024] Through the storage battery inside the controller 101, energy can be provided for devices such as the pump. The control module is used to control the start and stop of the pump. When the pump starts, the liquid medicine inside the medicine storage tank 102 is pumped to the distribution hose 103. The distribution hose 103 transports the liquid medicine to the two spray pipes 4 respectively. The distribution hose 103 is made of a flexible material and can undergo a certain deformation. Thus, when the spray pipe 4 rotates, it can stably connect the spray pipe 4.

[0025] Among them, in order to achieve the purpose of restricting the random rotation of the nozzle 4, the following technical solution is adopted in this device: two limiting holes 201 are provided in the support disk 2, a limiting groove 301 is provided in the limiting block 3, a limiting pin 302 is slidably installed in the limiting groove 301, the limiting pin 302 cooperates with the limiting hole 201, a spring pad 303 is fixedly connected to the limiting pin 302, a return spring 304 is sleeved on the limiting pin 302, and a pull ring 305 is fixedly connected to one end of the limiting pin 302.

[0026] With the two limiting holes 201 distributed at 90 degrees, the return spring 304 can provide a certain thrust to the spring pad 303. When the spring pad 303 receives the thrust, it will drive the limiting pin 302 to insert into the inside of the limiting hole 201. The cooperation between the limiting pin 302 and the limiting hole 201 can fasten the limiting block 3 and the support disk 2 together, thereby restricting the rotation of the rotating shaft 202 and thus restricting the rotation of the sleeve 203. There are two limiting holes 201, corresponding to the horizontal and vertical positions of the nozzle 4.

[0027] The working principle and usage process of the present utility model: When in use, the device needs to be placed in a suitable position, a certain amount of liquid medicine is added to the medicine storage box 102, the wheelbarrow 1 is pushed to the farmland, the limiting pin 302 is driven to move by pulling the pull ring 305, so that the limiting pin 302 moves out of the inside of the limiting hole 201, releasing the restriction on the nozzle 4, and then the nozzle 4 is rotated to the horizontal state. As Figure 1 shown, at this time the two nozzles 4 are horizontally opened, the pump is started to pump the liquid medicine into the nozzle 4, and the spray head 401 will atomize and spray the liquid medicine. By pushing the wheelbarrow 1 forward continuously, the spraying operation can be carried out. After the spraying is completed, the restriction on the nozzle 4 needs to be released again, and the nozzle 4 is rotated to the vertical state to avoid the problem that the nozzle 4 is broken when the wheelbarrow 1 moves to add medicine and contacts surrounding trees or reeds.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
