Abstract
Description
Technical Field
[0001] The invention relates to the technical field of fertilization spraying, and in particular to a fertilization spraying device for fruit trees. Background Art
[0002] During the planting process of fruit trees, the soil is generally fertilized regularly. However, during the seedling stage of fruit trees, their roots are not yet fully developed. Therefore, the nutrient needs of crops can be supplemented by spraying nitrogen, phosphorus and potassium macronutrient fertilizers on the leaves to make up for the lack of nutrient absorption by the roots. At the same time, some growth regulators can also be added to promote crop growth.
[0003] The traditional foliar fertilization method uses manual bucket fertilization to spray fertilizer liquid on the crop leaves through a circulating swing arm. This method is inefficient and time-consuming, and is not suitable for large-scale spraying. The existing foliar fertilization device carries the liquid storage tank through a mobile body, and sets the spraying frame on one side of the mobile body. The fertilizer is transported to the horizontally set nozzle through an infusion pipe to spray the leaf surface of the fruit tree. The use of machinery instead of manual labor improves the spraying efficiency. However, this spraying method is generally used for spraying on the leaves, and the fertilizer cannot be sprayed on the back of the leaves. Studies have shown that because the back of the leaves has less cutin and more stomata, nutrients are easy to absorb. The above-mentioned foliar spraying device sprays fertilizer on the front of the leaves through the nozzle, which cannot effectively act on the back of the leaves and reduces the absorption of fertilizer.

Press and drive the rotating gear 101 at the same time, so that the stirring component 9 in the storage tank can stir the fertilizer and water in real time, and the second rack 102 on the other side can push the spraying frame 31 to the interval between adjacent fruit trees that need to be sprayed and fertilized, and spray. After one spraying is completed, the staff will take out the moving block 13 from the limit socket 16. At this time, the telescopic rod 14 and the spring 15 need to return to their original positions, and then a pair of second racks 102 will return to their original positions and drive the rotating gear 101 to rotate. At this time, the spraying component 3 is placed between the vehicle body and the fruit tree, so that the front of the blade can be fertilized and sprayed.
[0034] The method of using the fruit tree fertilization spraying device of the present invention is as follows:
[0035] The second rack 102 is moved by the traction of the traction rope 12 under the action of the second slider 104, and the telescopic rod 14 and the spring 15 are pressed, and the rotating gear 101 is driven at the same time, so that the stirring component 9 in the storage tank stirs the fertilizer and water in real time, and the second rack 102 on the other side pushes the spraying frame 31 to the interval between adjacent fruit trees that need to be sprayed and fertilized.
[0036] The fertilizer is transported to the spraying pipe 33 through the first infusion pipe 17 by the pump body 8 arranged on the top of the mixing tank. The staff controls the cylinder 5 to push or pull through the controller on the push rod 11. At this time, the cylinder 5 will drive the first rack 4 to move. The first rack 4 is meshed with the half gear 344. As the first rack 4 moves, the half gear 344 will rotate, and the atomizing nozzle 345 will be driven to rotate through the support rod, so that the elevation angle of the atomizing nozzle 345 changes. The elevation angle of the atomizing nozzle 345 is changed in real time according to the situation of the tree, and the back of the leaves is sprayed with fertilizer.
[0037] After a spraying is completed, the staff will take out the moving block 13 from the limiting socket 16. At this time, the telescopic rod 14 and the spring 15 need to return to their original positions, and then the pair of second racks 102 will return to their original positions and drive the rotating gear 101 to rotate. At this time, the spraying assembly 3 is placed between the vehicle body and the fruit tree, and the front of the leaves can be fertilized and sprayed. Repeating the above steps will complete the fertilization and spraying of the leaves in the fruit tree garden.
