Description

Technical Field

[0001] The utility model relates to the technical field of seedling cultivation and pruning, and more specifically, to a tree seedling cultivation and pruning device. Background Art

[0002] A tree seedling pruning device is a tool or device used for pruning trees during the seedling raising process. It is usually composed of scissors, pruning shears, pruning saws and other tools, which are used to prune branches, roots or leaves of trees. Pruning can stimulate the growth of trees, especially the growth of side branches. Proper pruning can make trees form more branches and leaves, increase the area of ​​photosynthesis, and improve the efficiency of light energy utilization, thereby promoting the growth of trees.

[0003] Among them, it is found through searching that the patent application number CN202122013945.5 discloses a pruning device for tree seedlings, including a support frame, a pushing hydraulic cylinder, a push plate, a rotating barrel, a rotating motor, a lifting hydraulic cylinder, a support plate, a support block, a saw blade motor and a saw blade, the pushing hydraulic cylinder is horizontally arranged on the upper surface of the support frame, and the cylinder body of the pushing hydraulic cylinder is fixedly connected to the upper surface of the support frame, the piston rod of the pushing hydraulic cylinder is arranged toward the rotating barrel, and the push plate is arranged at the end of the piston rod in the pushing hydraulic cylinder;

[0004] The saw blade motor drives the saw blade to rotate, so that batches of seedlings can be pruned uniformly. At the same time, a ruler is set on the top plate, and the redundant branches in the seedlings can be pruned by rotating the saw blade. Compared with traditional manual pruning with pruning pliers, the use of saw blades for pruning improves work efficiency. However, this structure has limitations when used. It is not easy for workers to prune trees by hand. At the same time, it is not easy to position branches and leaves when pruning, which makes it easy for branches and leaves to move when subjected to shearing force, and it is not convenient when shearing.
