Pest and disease prevention tree trunk whitening device for forestry seedling raising

Abstract

The invention discloses a pest and disease prevention tree trunk whitening device for forestry seedling raising, and belongs to the technical field of forestry engineering. The pest and disease prevention tree trunk whitewashing device for forestry seedling raising comprises a moving seat, an arc rack is arranged on the inner wall of the arc circumference of an arc block, arc sliding grooves are formed in the upper side and the lower side of the outer wall of the arc block, penetrating grooves are formed in the middles of the arc sliding grooves, a U-shaped block is arranged in the middle of the inner side of the arc block, a motor is arranged in the middle of the upper side of the U-shaped block, a cylinder is arranged in the middle of the lower side of the U-shaped block, an annular curve groove is formed in the outer wall of the cylinder circumference, and an output shaft of the motor penetrates through the upper wall of the U-shaped block to extend into the U-shaped block and is sleeved with a gear. Through close fit of the structures, the device can automatically paint trees, the situation that thousands of or hundreds of trees are treated, the physical strength of workers is poor is avoided, and meanwhile, the situations that the coating is uneven due to manual spraying, and omission is likely to exist are avoided, mothproof, cold-proof and bacterium-proof effects cannot be achieved, and the attractiveness of urban trees is affected.

Description

technical field [0001] The invention relates to the technical field of forestry engineering, in particular to a whitening device for forestry seedlings to prevent pests and diseases on trunks. Background technique [0002] Forestry engineering refers to the activities of applying various engineering technologies to the cultivation, development and utilization of forest resources and the processing of forest products based on the principle of efficient utilization and sustainable development of forest resources. Forestry engineering includes forest area planning, forest cultivation and forest protection, forest mining, design and processing of wood products, design and manufacture of mining equipment, design and manufacture of wood product processing equipment, fire prevention technology and equipment in forest areas, etc. In the cultivation of forestry trees, it is necessary to whiten the trunks of trees so as to prevent moth, cold and bacteria. The existing operation method...

Problems solved by technology

The prior art publication number is that the literature of CN211563465U provides a kind of forestry engineering tree trunk whitening device, and the inventor finds that it has the following problems while realizing this prior art: 1, the device needs to manually hold the handle for spraying , similar to the traditional manual use of brushes, but the spraying needs to process thousands of trees, which is completely manual, which not only wastes manpower and material resources, but also makes the working manpower exhausted; 2. The device is easily caused by manual spraying. If the white coating is uneven, there may be omissions, which not only fails to prevent moths, colds, and bacteria, but also affects the appearance of urban trees; Spraying, its spraying efficiency is low, and the actual work effect is not good, in view of this, we propose a kind of device for forestry seedlings to prevent diseases and insect pests
