Description

Technical Field

[0001] The present invention relates to the technical field of ancient tree maintenance, and in particular to a spraying device for ancient tree maintenance. Background Art

[0002] During the long life process of ancient trees, bark trauma is caused by various reasons. If protection, treatment and maintenance measures are not taken in time, the ancient trees will often be eroded by rainwater, parasitic bacteria and eaten by pests. The wounds will gradually expand to form tree holes. Therefore, it is necessary to maintain the tree holes to prevent further decay of the ancient trees.

[0003] In the prior art, such as the patent with publication number CN118477776A, "A spraying device and spraying method for protecting the trunks of ancient and famous trees", this application can cover and spray trees by setting up an opening and closing covering component to improve the uniformity of the spraying. The cleaning component can be used to clean the trunks to remove dead skin before spraying them. This avoids the paint being sprayed on the dead skin that is easy to fall off, so that the paint can be kept on the trunks for a longer time, thereby improving the effect of the whitewashing operation and better protecting the trees; but the spraying equipment of this application cannot be used in tree hole maintenance.

[0004] Another example is the patent "Tree Hole Repair Construction Method for Rejuvenating Ancient Trees" with publication number CN110235681 B. This application maintains and uses the tree hole by grinding, disinfecting, spraying a tree hole protective layer and polishing the tree hole area, making the inner wall of the tree hole less susceptible to moisture erosion and, in turn, less susceptible to rot. This application combines conventional operating methods, and the method of spraying the tree hole protective layer is generally manual, but manual spraying operations are prone to uneven spraying and dead corners that cannot be sprayed, resulting in poor maintenance of the tree hole location.

[0023] Beneficial effects of the present invention:

[0024] (1) The present invention integrates the actions of purging, spraying the protective layer and drying the protective layer at the spray barrel position to achieve all-round maintenance treatment of the tree hole surface, so that the protective layer material is sprayed evenly and adheres stably, solving the problem of poor maintenance effect of spraying the tree hole protective layer caused by manual methods;

Under the action of the rotating shaft tube driven by the rotary drive mechanism, the spray tube rotates and purges the surface of the tree hole, so as to achieve all-round cleaning of the tree hole surface, which is efficient and convenient.

[0026] (3) After the tree hole surface is cleaned, a protective layer is sprayed on the tree hole surface.

Under the action of the rotary drive mechanism driving the rotating shaft tube to rotate, the spray barrel rotates to spray the tree hole surface, so as to achieve all-round spraying of the tree hole surface, and the spraying is uniform, efficient and convenient;

[0027] (4) After the protective layer is sprayed on the surface of the tree hole, it should be dried. In this application, natural air flow is delivered to the spray barrel through an air pipe with a gate valve. During the spraying process of the natural air flow, the heating mechanism heats the heat-conducting wire rod so that the heat-conducting wire rod passing through the spray hole heats the natural air flow. Under the action of the rotating shaft tube driven by the rotating drive mechanism to rotate, the spray barrel rotates to dry the surface of the tree hole, so that the sprayed protective layer quickly adheres to the surface of the tree hole, and the drying is efficient and convenient.

The heating seat 3 and the spray barrel 1 are detachably connected, and an end of the heating seat 3 away from the spray barrel 1 is provided with an integral rotating shaft tube 4, and the rotating shaft tube 4 is connected to the hollow inner cavity of the spray barrel 1 through a short pipe 5. The rotary drive mechanism drives the connected rotating shaft tube 4 to rotate 360°, and the adapter block 6 is rotatably connected to the pipe mouth end of the rotating shaft tube 4 away from the heating seat 3, and a T-shaped channel is provided on the adapter block 6, and the spray material pipe 7 with a gate valve and the air pipe 8 with a gate valve are respectively fixedly connected to the adapter block 6, and are connected to the rotating shaft tube 4 through the T-shaped channel.
