Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to an automatic spraying device for forestry seedling cultivation. Background Art

[0002] Nursery cultivation, or seedling cultivation, originally refers to the process of growing seedlings in a nursery, hotbed, or greenhouse in preparation for transplanting to the field. Today, forestry nurseries are often grown in greenhouses to accelerate their growth. During this period, spraying equipment is used to apply pesticides to the seedlings for pest and disease control, mitigating or preventing the risk of pathogens and insects from harming the seedlings.

[0003] A search revealed a Chinese patent application with the authorization announcement number CN211861599U, which discloses a spraying device for forestry seedling cultivation. The device comprises a base plate, a spraying device fixedly connected to the left side of the upper surface of the base plate, universal wheels fixedly connected to the four corners of the lower surface of the base plate, a drag handle fixedly connected to the middle of the right side of the base plate, and a medicine storage box fixedly connected to the right side of the upper surface of the base plate. The spraying device for forestry seedling cultivation, through the coordination of a discharge pipe, a feed pipe, a support plate, a spraying pipe, a spraying pump, an operating handle, and a stirring rod, avoids the occurrence of low spraying efficiency caused by carrying the sprayer on the back, thereby reducing the labor intensity of the staff. The coordination of an adjustment rail, an adjustment block, a cut-off pin, a support plate, and a push rod motor avoids the occurrence of reduced product applicability due to poor spray height adjustment, thereby shortening the time required to adjust the spray height.

[0004] In actual operation, it was found that the above scheme still has at least the following defects: when the existing forestry seedling spraying device is in use, the staff still needs to push the spraying device forward by hand to spray all the seedlings. The degree of automation is low, which increases the workload of the staff, is time-consuming and labor-intensive, and has low work efficiency. Moreover, during the hand-pushing spraying device forward for spraying, it is difficult to control the spraying device to maintain a uniform speed, and because the direction of the liquid sprayed from the spray pipe is certain, it is easy to cause the spraying of the seedlings to be not uniform and comprehensive, resulting in a decrease in the spraying quality. For this reason, we propose an automated forestry seedling spraying device to solve the above problems. Summary of the Invention

When the booster pump 10 is running, the electric slide 3 is controlled to slide horizontally and linearly on the electric guide rail 2. In use, the liquid medicine in the medicine box 5 can be first pumped into the fixed box 13, so that the liquid medicine in the fixed box 13 can enter the liquid inlet cavity 8 through the discharge pipe 14, and finally the liquid medicine can be sprayed out from the multiple nozzles 9.

In the spraying process, the liquid medicine generated by the liquid medicine discharged from the liquid outlet pipe 12 is used. Part of the kinetic energy can drive the arc blade 16, the drive vertical shaft 15 and the active bevel gear 17 to rotate, and the meshing transmission effect of the active bevel gear 17 and the driven bevel gear 19 is utilized, and the meshing transmission effect of the plurality of second transmission bevel gears 21 and the corresponding first transmission bevel gears 20 is utilized to control the rotation of the plurality of nozzles 9, and then the centrifugal force generated when the plurality of nozzles 9 rotates is utilized to make the sprayed liquid sprayed evenly and comprehensively on the seedlings, thereby achieving the purpose of uniform spraying and improving the quality of spraying on the seedlings. During the horizontal and linear movement of the shaft 23, the stirring rod 24 and the spur gear 25, the meshing transmission effect of the spur gear 25 and the rack 27 can be used to control the stirring shaft 23 to drive the stirring rod 24 to rotate, so that the medicine liquid in the medicine box 5 can be stirred evenly, avoiding the precipitation and stratification of the medicine liquid, ensuring the uniform concentration of the medicine liquid sprayed from multiple nozzles 9, and thus making the concentration of the medicine liquid sprayed on the seedlings uniform, further improving the quality of spraying the seedlings. After the spraying is completed, stop the sliding of the electric slide 3 and stop the operation of the booster pump 10.
