Description

Technical Field

[0001] The utility model relates to the technical field of fertilizing devices, in particular to a telescopic spraying device for liquid fertilizer in tobacco fields. Background Art

[0002] In tobacco field cultivation, the spraying of liquid fertilizer is of vital importance. However, the existing fertilizer spraying device is too simple and cannot meet the requirements of tobacco field fertilization. In order to solve this technical problem, technicians have made many attempts. For example, Chinese patent CN211721608U discloses a forestry pest control spraying device, whose driving assembly includes lifting and telescopic components, which can tilt the adjustment column through the angle adjustment mechanism and use the swing mechanism to rotate the spray nozzle at multiple angles, thereby expanding the spraying area. However, this solution still has the problems of fixed spraying height and inaccurate fertilizer flow rate control, which affects the fertilization effect. Specifically, the equipment lacks a height adjustment mechanism and cannot adapt to the requirements of tobacco leaf height in different tobacco fields; at the same time, the flow rate control is not accurate enough, making it difficult to achieve uniform fertilization.

The dispensing pipe extends downward and horizontally to the surrounding areas to provide a spraying rod, and a number of spraying heads are provided at the bottom of the spraying rod.

[0009] This technical solution uses a telescopic mechanism to flexibly adjust the spraying height of liquid fertilizer, thereby improving fertilization efficiency; adjusting the regulating valve in the spraying mechanism can accurately control the fertilizer flow rate to ensure uniform fertilization; the water absorption plate effectively collects the residual liquid under the spray head, avoiding resource waste and environmental pollution. Specifically, the connecting valve connects the fertilizer tank with the driving pump to ensure that the fertilizer can smoothly enter the pump body; the driving pump pushes the fertilizer to flow in the pipeline; the hose can adapt to the expansion and contraction changes of the telescopic mechanism to ensure that the fertilizer can be continuously and stably delivered to the spraying mechanism; the spraying height can be precisely adjusted by superimposing and extending the telescopic rod I, telescopic rod II and telescopic rod III; the water absorption plate set on the side of the telescopic rod I is used to protect the spray head after use to prevent dust from entering and clogging the spray head, and at the same time recover the liquid remaining on the spray head; the regulating valve adjusts the fertilizer flow through the hose by changing the cross-sectional area or opening degree of the channel, thereby controlling the spraying speed; the distribution pipe evenly distributes the fertilizer to different spray rods, and the spray rods then spray it evenly on the tobacco field; each group of distribution pipes is set at 60° intervals to ensure the uniformity of spraying and increase the coverage area of ​​the fertilizer.
