Abstract
The utility model relates to a bush cutter, comprising a power assembly and a workingbeam assembly. The utility model is characterized in that a detachable joint is arranged on the workingbeam, the detachable joint is composed of a detachable sleeve pipe and a shaft coupling head fixed in an inner hole of a bearing, and a rolling bearing is arranged in the detachable sleeve pipe; positioning through holes are arranged on a wall of a sleeve pipe for the workingbeam and a wall of a sleeve pipe for the detachable joint, and the sleeve pipe for the workingbeam and the sleeve pipe for the detachable joint are positioned through bolts. The utility model has the advantages of simple structure and convenient use; due to the disconnection and the connection of the workingbeam, the utility model is convenient to carry, produce and transport.
Description
The utility model belongs to mechanical field, particularly a kind of improvement of brush saw.
The existing brush saw that uses generally is divided into two class backpacks and the negative formula of side, mainly (comprise handgrip, switch, working beam and cutter head by power assembly (comprising back of the body frame, power and clutch) and working beam assembly, backpack also contain a flexible axle) form, working beam is made up of sleeve pipe and interior axle, its length designs generally more than 1.4 meters according to purposes, long and can not dismantle because of working beam length, carried, keeping and production and transport bring many inconvenience.
The purpose of this utility model is the brush saw that a kind of working beam of design can disconnect.
Task of the present utility model is to realize like this, working beam in the working beam assembly is provided with one and disconnects head, disconnecting head is made up of with an axle coupling head that is fixed on brearing bore the sleeve pipe that disconnects that is provided with rolling bearing, working beam sleeve pipe and disconnect the headgear tube wall and be provided with positioning through hole, and locate by bolt.Disconnect the middle part that is located at working beam as first, working beam is divided into two, length shortens and is easy to carry etc., tip side insertion with working beam during use disconnects in the head, the interior spindle nose of working beam is docked with an axle coupling head, alignment work rod bush and the positioning through hole that disconnects on the headgear pipe, bolting on to form a working beam integral body.
The utlity model has characteristics simple in structure, easy to use, the disconnecting in conjunction with the disconnecting of complete machine remaining part of working beam can make the brush function lay in the work box, is easy to carry keeping and production and transport.
Below in conjunction with legend the utility model is described further:
Fig. 1 backpack brush saw schematic diagram.
Fig. 2 disconnects a schematic diagram.
Power assembly with reference to Fig. 1 backpack brush saw comprises gasoline-engine driven machine 2 and the clutch 3 that is installed on the back of the body frame 1, the working beam assembly comprises the flexible axle 4 that connects with clutch, flexible axle 4 connects with working beam 5, the end of working beam 5 is provided with cutter head 6, handgrip 7,8 and switch base 9 before and after working beam 5 is provided with, flexible axle 4 is located by bolt with clutch 3 and working beam 5, extracting bolt can take above three parts apart, and in the negative formula brush saw of side, not having flexible axle, working beam is directly by being bolted on the clutch.Establish one at the middle part of working beam 5 and disconnect 11, take apart working beam 5 is divided into two.
With reference to Fig. 2, the outer surface that disconnects head is one to disconnect sleeve pipe 21, disconnect and be provided with rolling bearing 22 in the sleeve pipe 21, be fixed with a coupling head 23 on bearing 22 endoporus, square hole 24 in the two ends of axle coupling head 23 are equipped with, and the termination of axle 25 is square toes 26 in the working beam, square toes 26 can insert in the square hole 24, formation reliably is coupling again easily, and working beam sleeve pipe 27 is provided with positioning through hole 28 with the wall that disconnects sleeve pipe 21, by bolt 29 location, disconnect and also establish oil hole 30 on headgear pipe 21 and the working beam sleeve pipe 27, and be furnished with an oil-hole plug 31, and prevent that dust from entering, closely hold tightly first watch for making working beam and disconnecting, respectively establish a line of rabbet joint 32 disconnecting headgear pipe 21 two ends, be fixed with butterfly sheet 33 on the sleeve outer wall of the line of rabbet joint 32 both sides, butterfly sheet 33 is provided with bolt hole 34, and by bolt two butterfly sheets is clamped.
