DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to further explain the technical solution of the present utility model, the following is elaborated in detail through specific embodiments.

[0020] Please refer to Figure 1 、 Figure 2 and Figure 3, the present utility model provides a pesticide application device for modern agriculture, which includes a main pipeline 1. A branch pipeline 2 is butted on the main pipeline 1. A nozzle 3 is threadedly connected to the branch pipeline 2. A nozzle protection structure 4 is provided on the nozzle 3;

[0021] The main pipeline 1 is connected to a liquid medicine pump. The liquid medicine pump inputs agricultural liquid medicine into the main pipeline 1, and then enters the branch pipeline 2 and is sprayed out by the nozzle 3. The main pipeline 1 is buried inside the planting land, so that the nozzle 3 is above the planted plants. The liquid medicine sprayed out by the nozzle 3 will be poured on the planted plants to achieve the effect of pesticide application.

[0022] Please refer to Figure 3 and Figure 4 , the present utility model provides a pesticide application device for modern agriculture. The nozzle protection structure 4 includes a support rod 41. A support rod 41 is integrally formed on the top end surface of the nozzle 3. A fixing cylinder 42 is integrally formed in the middle of the support rod 41. A spring 43 is arranged inside the fixing cylinder 42. A connecting rod 44 is arranged at the lower end inside the fixing cylinder 42 in a vertically sliding connection manner. The top end of the connecting rod 44 is connected to the lower end of the spring 43. A protection plate 45 is arranged at the lower end of the connecting rod 44. A conical plug 46 is integrally formed at the bottom of the protection plate 45, and the bottom end surface of the plug 46 is flat. The plug will be inserted into the nozzle 3 opening. An inward concave arc surface is arranged at the upper end of the plug 46, which improves the sealing effect. At the same time, the conical plug 46 also has a flow splitting function, so that the sprayed liquid medicine is in a diffused form, improving the spraying effect. The flat bottom end surface of the plug 46 is beneficial for the liquid medicine to better push the plug 46;

[0023] A rotatably connected knob 47 is arranged at the top of the fixing cylinder 42. A screw rod 48 is fixed at the bottom of the knob 47. An adjusting block 49 is threadedly connected to the surface of the screw rod 48. One end of the spring 43 is connected to the adjusting block 49. There is a distance between the screw rod 48 and the connecting rod 44 to avoid obstruction of the connecting rod 44 and can also limit the connecting rod 44 to prevent the protection plate 45 from moving upward excessively and losing the function of splitting the liquid medicine;

[0024] When the spray head 3 sprays medicine, the liquid medicine will push the plug 46, causing the protection plate 45 to slide upward. Then the connecting rod 44 will slide upward along the inner wall of the fixed cylinder 42, compressing the compression spring 43, so that the spring 43 is compressed to generate elastic force. Under the action of the plug 46, the liquid medicine will be sprayed diffusely. When the spraying stops, the spring 43 will push the connecting rod 44 downward to reset the protection plate 45, protecting the spray orifice of the spray head 3. To protect the spray head 3 when it is waiting to be used, avoiding the problem that dust accumulates on the spray head 3 and causes blockage, reducing the failure rate. Rotate the knob 47 to make the screw 48 rotate. When the screw 48 rotates, the adjusting block 49 will slide along the surface of the screw 48, thereby driving the spring 43 to adjust the elastic force of the spring 43, avoiding the problem that the elastic force of the spring 43 is too large to push the protection plate 45 by the liquid medicine.

[0025] The above are only the preferred examples of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
