Description

Technical Field

[0001] This application relates to the technical field of tree trunk repair equipment, and in particular to an internal support structure for repairing tree holes. Background Art

[0002] Trees are an important part of nature. They not only provide support for the ecological environment but also offer various resources and aesthetic feelings to human society. However, due to natural factors or human reasons, trees may be damaged and form tree holes. If the tree holes are not repaired, it may lead to further deterioration of the tree structure and even threaten the survival of the trees.

[0003] As disclosed in the authorized patent No. CN220123511U, a tree trunk repair device includes a vehicle body, a plurality of counterweights fixed on the top surface of the vehicle body near the right end, and a material feeding pipe located above the vehicle body. A material feeding box connected to the inside of the material feeding pipe is fixed on the left side surface of the material feeding pipe. A rectangular groove connected to the inner cavity size is provided on the top surface of the material feeding box, and an adjusting plate slidably inserted into the rectangular groove on the top surface of the material feeding box is provided inside the material feeding box. In this utility model, the feeding pipe of the external feeding device is tightly sleeved with the feeding pipe. Through the cooperation of the vehicle body and the lifting mechanism, the discharging pipe can be made to correspond to the position of the tree hole to be filled. Through the cooperation of the motor, the auger, the material feeding pipe, the material feeding box, and the discharging pipe, the tree hole can be filled. Through the adjusting mechanism, the flow rate of the filling material passing through the material feeding box can be adjusted, so that the filling speed can be adjusted according to the size of the tree hole, thereby preventing the phenomenon of waste of filling material caused by too fast filling speed.

[0004] However, in the prior art, there is a problem that the support structure cannot provide sufficient internal support, resulting in an unsatisfactory repair effect. Secondly, traditional filling materials may not have sufficient structural strength to withstand the pressure brought by the growth of trees for a long time, or may not have good biocompatibility, affecting the healthy growth of trees.
