Description

Technical Field

[0001] The utility model relates to an environmentally friendly portable device for spraying fruit trees, belonging to the technical field of tree spraying. Background Art

[0002] In agricultural planting practice, in order to improve the cold resistance of fruit trees and prevent diseases and pests, agricultural workers usually use a special paint to whitewash the trunks of fruit trees. Whitewashing is usually carried out before winter. By evenly brushing the paint on a section of the fruit tree trunk 1 to 1.5 meters above the ground, it can effectively reflect sunlight, reduce the heat absorption of the trunk during the day, and then reduce the thermal stress caused by the temperature difference between day and night on the trunk, thereby preventing the trunk from freezing and cracking. In addition, white paint also has the effect of sterilization and insect repellent, which plays a positive protective role in the healthy growth of fruit trees.

[0003] The inventors have discovered that the prior art has at least the following technical problems:

[0004] When whitewashing the trunks of fruit trees, workers need to work around the trunks. This operation is not only cumbersome, but also prone to missed areas due to limited sight or operating angles. The existing spraying method is to spray under pressure, which requires spraying around the trunks, which is very labor-intensive. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an environmentally friendly portable device for spraying fruit trees, so as to avoid workers having to operate around the tree trunk and spray on one side, thereby greatly improving the efficiency of spraying.

[0006] The environmentally friendly portable device for spraying fruit trees of the utility model comprises a support frame, the support frame is provided with an annular opening for accommodating a tree trunk, a rotatable spraying assembly is installed in the annular opening; a driving mechanism for driving the spraying assembly to rotate is provided inside the support frame;

[0007] The upper and lower ends of the support frame are respectively equipped with roller positioning components that can move up and down along the tree trunk;

[0008] A handle is arranged at one end of the support frame away from the annular opening, and switches for controlling the spraying assembly and the driving mechanism are respectively installed on the handle or on the support frame near the handle.

[0009] Furthermore, the spraying assembly includes an arc-shaped plate rotatably mounted in the annular opening, a plurality of spray heads are mounted on the inner side of the arc-shaped plate, and the arc-shaped plate is composed of two pieces symmetrically mounted on the annular opening.

[0010] Furthermore, guide mechanisms are respectively installed on the upper and lower parts of the arc plate, and the arc plate is installed on the annular opening through the guide mechanisms.

[0011] Furthermore, the guide mechanism includes a guide screw installed on the arc plate, and an arc groove is provided on the support frame corresponding to the guide screw.

[0012] Furthermore, the driving mechanism includes electric cylinders respectively installed on two side plates of the support frame, a rack is installed at the output end of the electric cylinder, a track corresponding to the rack is provided on the side plate for the rack to slide inside, and a gear plate that cooperates with the rack is installed on the outer side of the arc plate.

[0013] Furthermore, the roller positioning assembly includes a roller frame, on which two rotating wheels are arranged in parallel, support seats are respectively installed at the upper and lower ends of the support frame, the roller frame is slidably installed on the support frame, and a preload spring is installed between the roller frame and the support seat.

[0014] Furthermore, an adjusting member for adjusting the elastic force of the preload spring is installed at one end of the support seat.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model realizes single-side spraying by setting a rotatable spraying assembly and a driving mechanism, avoiding the tedious operation of workers around the tree trunk and the occurrence of missed brushes, greatly improving the spraying efficiency. The design of the roller positioning assembly enables the device to fit the tree trunk closely and adjust with the change of the trunk shape, improving the adaptability and stability of the spraying.
