Embodiment Construction

[0011] Depend on figure 1 It can be known that the lifting arm 7 is pulled and put by the luffing hoist 4, so that the telescopic rod 9 suspended thereunder can move back and forth with the tree clamp 14 and the underwater hydraulic chain saw 15 installed at the bottom. Lifting arm 7 is installed on the rotating platform 3, and rotating platform 3 can rotate 360 ​​° on board by slewing bearing 16, thereby drives telescopic link 9 to move left and right together with tree clamp 14 and underwater hydraulic chainsaw 15. The up and down movement of the tree clamp and the hydraulic chain saw is completed by pulling or putting the main winch 5: when the main winch unwinds the rope, the telescopic rod automatically extends due to the weight, and retracts when the main winch draws the rope. In this way, we can operate the tree clamp and hydraulic chain saw when the boat or raft is stationary on the water, and move up and down tens of meters, left and right for more than ten meters, an...

Abstract

Disclosed is an underwater feller mounted on a boat or raft. An underwater hydraulic chain saw is mounted at the bottom of a telescopic bar through a shaft and axially coincides with the telescopic bar, a rotary shaft of a tree clamp is sleeved on the shaft, an underwater searchlight and an underwater camera are mounted at a clear water outlet reserved on the telescopic bar, the upper end of the telescopic bar is suspended below a crane jib, the crane jib is mounted on a rotating platform, and the rotating platform is mounted on the raft or boat through a slewing bearing. The hydraulic chain saw and the tree clamp below the telescopic bar are optionally moved for research within a range 10m in vertical height and about 10m in longitudinal and transverse distances under telescoping of the telescopic bar, luffing of the jib and rotation of the platform. The telescopic bar which is hollow can be used for pumping surface clear water to be around the camera so as to improve underwater vision. The tree clamp is used for firmly clamping a targeted tree which is cut off at the root and pulled out of the water by the chain saw by rotating the telescopic bar. The raft is assembled on site with a plurality of sealed steel tanks or hollow plastic barrels. Felling speed of the underwater feller is hundreds of times higher than that of manual diving felling.

Description

technical field [0001] The invention belongs to construction machinery, in particular to a device installed on a boat or a raft to cut off submerged trees and drag them to the water surface: an underwater logging machine. Background technique [0002] The amount of wood required in my country is increasing year by year, and due to limited domestic forest resources, it has to be imported in large quantities. But no matter where a large number of deforestation is not conducive to the earth's ecological environment. After investigation, it is known that some foreign reservoirs did not cut down the virgin forest in the submerged area when the dam was built, so that a large amount of high-quality wood sank underwater and could not be used. For example, Dr. Blommestein-see in Suriname, South America, has a reservoir area of ​​1,560 square kilometers and is the largest reservoir in the world. When the dam was built in 1960, the tropical rainforest in the reservoir area was not ha...
