Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: be provided with saw blade in the head-shield, saw blade is fixed on the output shaft, output shaft is driven by armature shaft, between described armature shaft and output shaft by one-level belt and second belt transmission, described one-level belt is arranged between armature shaft and the jackshaft, and described second belt is arranged between jackshaft and the output shaft.Cutting machine adopts two belt transmission; realize that armature power is through the remote transmission of jackshaft to output shaft; be convenient to the reasonable setting of parts such as cutting machine armature; thereby drive saw blade and realize cutting movement; can obviously improve the mechanicalness noise that gear drive brings; belt creep when machine transships can prevent that motor overload from playing the effect of protection motor in addition.
As preferably, described armature shaft is provided with the fan blade that is coaxially set with it; Or described jackshaft is provided with the fan blade that is coaxially set with it; Or fan blade is set respectively on armature shaft and jackshaft.The rotation of armature shaft or jackshaft self provides power source for the rotation of fan blade, the driving fan blade rotates, in the process of cutting operation, the rotation of fan blade impels the circulation of belt ambient air, strengthened the belt radiating effect, can prevent that transmission is overheated, improve the transmission performance of belt, prolong the service life of belt.
As preferably, described one-level belt and second belt are provided with belt housing outward, help protecting operator or cutting machine other people person's personal safety, prevent that also dust from falling into simultaneously, and described belt housing is provided with air outlet, is beneficial to the heat radiation of belt; Described air outlet corresponds respectively to armature shaft and jackshaft position and is provided with, and the air in the belt housing forms convection current between the other air outlet of the other air outlet of armature shaft and jackshaft, strengthen the radiating effect of belt; Described air outlet is the strip engraved structure, prevents that foreign matter from entering, and has protected the transmission environment of belt.
As preferably, described armature shaft is provided with first small belt pulley, described jackshaft is provided with the first belt pulley and second small belt pulley, described output shaft is provided with second largest belt pulley, described one-level belt is located on first small belt pulley and the first belt pulley, and described second belt is located on second small belt pulley and the second largest belt pulley.The power of armature one-level between first small belt pulley and first belt pulley is quickened, and through second small belt pulley and second largest belt pulley double reduction, finally drives the rotation of saw blade again.
As preferably, described fan blade is provided with the fan blade locating shaft, and fan blade also can directly be installed on jackshaft or the armature shaft by its endoporus, and the air-out direction of fan blade is towards armature shaft or jackshaft, fricative heat between belt and belt pulley is in time taken away, strengthened radiating effect.
Therefore; the utlity model has the remote transmission that can realize between armature power and saw blade place output shaft; obviously reduce the noise in the cutting machine operating process simultaneously; belt creep when machine transships; can prevent that motor overload from playing the effect of protection motor; can prevent effectively that the transmission of cutting machine is overheated, improve the belt transmission performance, the characteristics such as service life that prolonged belt.
