Background technology:
Single-blade cast-cutting saw in the past can only cut homogenous material under the situation of not changing saw blade, and cutting efficiency is lower, the operation effort.In addition, also there is following shortcoming in existing cutting machine: 1, use power supply or power pump to do power mostly, mobility is poor, can't satisfy the rescue work in high level, field or complicated place; 2, after the power set output, adopt chain-drive mechanism to carry out transmission, damage engine and gear easily, the reliability of transmission is relatively poor.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of cutting efficiency height, rapid operation, maneuverability, the incorgruous cast-cutting saw of twolip of many uses, reliable operation are provided.
In order to realize the foregoing invention purpose, the present invention has adopted following technical scheme:
The incorgruous cast-cutting saw of a kind of twolip; Comprise power set, gear drive and cutter sweep; Said cutter sweep comprises saw blade I and the saw blade II that is arranged side by side, and said gear drive comprises under I level power transmission shaft, bevel gear pair, II level power transmission shaft, output pinion, the output gear wheel, III level power transmission shaft, III level driving sleeve in gear wheel, the output, wherein; II level power transmission shaft is in transmission connection through bevel gear pair and I level power transmission shaft; Output pinion is installed on the II level power transmission shaft, and gear wheel lays respectively at the upper and lower end of output pinion and is in transmission connection with it gear wheel with exporting down in the output, and gear wheel is installed as one to III level power transmission shaft with exporting down; III level driving sleeve is coated at III level power transmission shaft and goes up gear wheel with output and is installed as one; The front end of III level power transmission shaft is stretched in III level driving sleeve outward, and saw blade I is installed on the overhanging end of III level power transmission shaft, and saw blade II is installed on the front end of III level driving sleeve.
Also comprise a belt gear, said belt gear comprises driving pulley, driven pulley and V-belt, and said driven pulley is installed on the I level power transmission shaft.
The output shaft of said power set is provided with clutch and driven disc, and said driving pulley is connected through spline and driven disc.
Said power set are gasoline engine.
The present invention has following advantage with respect to prior art:
1, just as the operation principle of scissors, cutting speed is 5-8 a times of original cutting tool to the incorgruous cutting of two saw blades, has improved cutting efficiency greatly.
2, adopt two incorgruous cuttings of saw blade, each cutting speed and shearing force of opening saw blade is identical, but in the opposite direction, cancels each other, and whole cutting process need firmly can easily not accomplished.
3, under the situation of not changing saw blade, can cut nearly all materials such as steel, copper aluminium, timber, plastics, rubber, vehicle glass simultaneously, promoted the performance and the purposes of cast-cutting saw greatly.
4, adopt gasoline engine to do power, make the mobility of machine and flexibility strengthen, can be fit to most of environment and occasion and use.
5, adopt belt transmission structure: when when sawing, running into very big resistance or cutting force, the belt gear in self-shield engine and the gear-box that can skid has been avoided the damage of chain transmission to engine and gear.
Description of drawings:
Fig. 1 is the structural representation of the incorgruous cast-cutting saw of twolip of the present invention.
Fig. 2 is the cross-sectional schematic of the incorgruous cast-cutting saw fore-end of twolip of the present invention.
The specific embodiment:
As depicted in figs. 1 and 2, according to the incorgruous cast-cutting saw of twolip provided by the invention, comprise power set (not shown), gear drive 1 and cutter sweep 2.Cutter sweep 2 comprises the saw blade I 21 and saw blade II 22 that is arranged side by side, and gear drive 1 comprises I level power transmission shaft 11, bevel gear pair 12, II level power transmission shaft 13, output pinion 14, exports gear wheel 16, III level power transmission shaft 17, III level driving sleeve 18 in gear wheel 15, the output down.Wherein, II level power transmission shaft 13 is in transmission connection through bevel gear pair 12 and I level power transmission shaft 11; Output pinion 14 is installed on the II level power transmission shaft 13, and gear wheel 15 lays respectively at the upper and lower end of output pinion 14 and is in transmission connection with it gear wheel 16 with exporting down in the output, and gear wheel 15 is installed as one to III level power transmission shaft 17 with exporting down; III level driving sleeve 18 is coated at III level power transmission shaft 17 and goes up gear wheel 16 with output and is installed as one; The front end of III level power transmission shaft 17 is stretched in III level driving sleeve 18 outward, and saw blade I 21 is installed on the overhanging end of III level power transmission shaft 17, and saw blade II 22 is installed on the front end of III level driving sleeve 18.
Also comprise a belt gear 3, belt gear 3 comprises that driving pulley 31, driven belt 32 take turns and V-belt 33, and driven pulley 32 is installed on the I level power transmission shaft 11.
