Description

Technical Field

[0001] This utility model relates to the field of tobacco fertilization technology, specifically a precision sprayer for tobacco foliar liquid fertilizer. Background Technology

[0002] As an important economic crop, tobacco requires careful fertilization management during its growth process. Tobacco fertilization mainly includes two parts: base fertilizer and top dressing, aiming to ensure that tobacco plants receive sufficient nutrients throughout their growth cycle. In addition to traditional soil fertilization, foliar fertilization is receiving increasing attention in tobacco production. Foliar fertilization involves spraying a fertilizer solution directly onto the tobacco leaves. This method has advantages such as low dosage, rapid absorption, and high efficiency, which are beneficial to tobacco growth.

[0003] In existing technologies, fertilization devices for tobacco cultivation can avoid affecting the fertilization effect by stirring the fertilizer at the bottom of the fertilizer tank. However, the fixed position of the stirring blades and other structures makes it difficult to fully and evenly mix the liquid fertilizer. Furthermore, the spray plate sprays the fertilizer solution at an arc angle, making it difficult to directly and accurately spray the fertilizer solution onto the tobacco leaf surface. The fixed height also fails to meet the foliar fertilization needs during tobacco cultivation. Therefore, it is necessary to improve the tobacco foliar liquid fertilizer precision sprayer to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a precision sprayer for liquid fertilizer on tobacco leaves to solve the problems mentioned in the background art.

A spring 918 is fixedly connected inside the connecting box 914. A slider 915 is fixedly connected to the bottom of the spring 918. A filter plate 916 is fixedly connected to the bottom of the slider 915. A guide plate 917 is fixedly connected to the top of the filter plate 916, which facilitates the filter plate 916 to reciprocate up and down against the outer wall of the cam 913. This satisfies the need to filter the liquid fertilizer on the tobacco leaves entering the liquid inlet tank 5 while preventing the filter plate 916 from becoming clogged.

[0020] Furthermore, the cam 913 contacts the filter plate 916, and the connecting box 914 and the slider 915 are respectively provided with grooves, and the slider 915 is slidably connected inside the groove, which makes the filtration process more stable.

[0021] Furthermore, the stirring assembly 92 includes a support base 921, which is fixedly connected to the top of the fertilizer storage box 3. A second motor 922 is fixedly connected to the top of the support base 921, and a first bevel gear 923 is fixedly connected to the output end of the second motor 922.

[0024] Furthermore, the residual gear 104 meshes with the gear post 105, and the limiting plate 103 and the second connecting rod 102 are provided with grooves at corresponding positions, and the second connecting rod 102 is movably connected inside the groove, which facilitates a more stable spraying process.

[0025] In actual operation, when this device is used, all electrical connections and moving parts are first treated with existing technologies such as sealing rings for dust and water protection. The operator then pushes the device, along with the self-locking casters 2, to move it to the designated location. Through the liquid inlet tank 5 and the guide plate 917, liquid fertilizer for tobacco leaves is introduced into the fertilizer storage tank 3. The first motor 911 operates, causing the first connecting rod 912 to rotate, which in turn interacts with the cam 913. The filter plate 916 moves, cooperating with the spring 918 to make the slider 915 slide inside the connecting box 914, thereby causing the filter plate 916 to reciprocate up and down against the outer wall of the cam 913. This satisfies the need to filter the liquid fertilizer on the tobacco leaves entering the liquid inlet box 5 while preventing the filter plate 916 from becoming clogged. The cover plate on the top of the liquid inlet box 5 and the protective door on the back of the liquid inlet box 5 facilitate subsequent cleaning of the filter plate 916. The second motor 922 operates, causing the first bevel gear 923 to rotate, which, in conjunction with the second bevel gear 925, causes the rotating frame 924 to rotate inside the fertilizer storage box 3, thereby rotating the stirring blade 926, which, in conjunction with the third bevel gear... 928. The mixing frame 927 rotates inside the rotating frame 924 to ensure that the liquid fertilizer for tobacco leaves inside the fertilizer storage box 3 is thoroughly mixed evenly, avoiding stratification. The hydraulic cylinder 7 operates to move the connecting frame 8, thereby adjusting the height of the spray plate 106. The connecting pump 6 operates, working with the flexible connecting pipe and the spray plate 106 to start the spraying process. The third motor 101 operates to rotate the second connecting rod 102, which, in conjunction with the limiting plate 103, causes the residual gear 104 to rotate back and forth. In conjunction with the gear column 105, the spray plate 106 rotates back and forth, thereby increasing the spraying range and ensuring uniform spraying of fertilizer onto the tobacco leaves.
