Embodiment Construction

[0012] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] When the nail-toothed feed roller works, the tip of the tooth (such as image 3 ) end enters the cylindrical surface of the trunk, and its rotation drives the trunk to move stably and quickly in the axial direction. Among them, the contact area s of the welding part, the tooth height h, the angle α between the inclined surface and the bottom surface, and the distribution density of the nail teeth can all be changed according to the actual work requirements.

[0014] Due to the above-mentioned structure, the present invention has the advantages of convenient installation and use, high grinding precision, wide application range, stable feeding, and fast feeding speed.

[0015] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person familiar w...

Abstract

The invention relates to field of forestry felling machinery, a feed roller of combined feller which comprises two parts as spike teeth and roller matrix, with characteristic of multiple vertical spike teeth distributed around circular pattern of the roller matrix. The top ( shown in picture 3) of spike-tooth feed roller enters cylindrical surface of tree trunk, with its rotation bringing steady and fast axial movement to the trunk. The invention has advantages such a simple structure, convenient assembly and use, highly accurate grinding, wide range of application and low cost, etc.

Description

technical field [0001] The invention relates to the field of forestry felling machinery, in particular to a felling head feed roller of a combined felling machine. Background technique [0002] At present, with the continuous increase of labor costs, the felling of a large number of trees in forest farms, farms and municipalities can no longer rely solely on manpower. There is an urgent need for a special logging machine to replace manpower. A series of actions of branching, measuring and peeling. The circumferential working surface of the felling head feed roller of the existing combined logging machine has a straight-toothed surface structure. When processing fallen logs, the feeding is unstable and the feeding speed is slow due to the contact surface defects between the circumferential working surface and the felled logs. Work efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a feed roller of a felling head of a c...
