Wherein: 1-chain, 2-rear wheel driving chain wheel, 3-rear wheel, 4-rear wheel shaft, 5-fixing plate, 6-stressing hand disc, 7-clutch gear, 8-chain wheel assembly, 81-auxiliary gear, 82-chain wheel, 9-stressing shaft, 10-clutch pin, 11-clutch positioning piece, 12-front wheel and 13-cutting blade.
Detailed Description
As shown in fig. 1-3, the travelling mechanism of the cutting machine of the present invention comprises a driving device, a chain 1, and a rear wheel transmission sprocket 2, wherein two rear wheels 3 of the cutting machine are connected by a rear wheel shaft 4, and the rear wheel transmission sprocket 2 is sleeved on the rear wheel shaft 4 and is located beside any one of the rear wheels 3; a driving device is arranged on the machine body of the cutting machine, and the rear wheel transmission chain wheel 2 is connected with the driving device through a chain 1.
In the embodiment, the driving device comprises a fixing plate 5, a force application hand disc 6, a clutch gear 7, a chain wheel assembly 8 and a force application shaft 9, wherein the fixing plate 5 is fixedly arranged on a machine body of the cutting machine and is positioned above a rear wheel transmission chain wheel, the clutch gear 7 is connected with the fixing plate 5 through the force application shaft 9 penetrating through the center of the clutch gear, a clamping part is arranged on the clutch gear 7 and comprises a clutch pin 10 and a clutch positioning piece 11, the clutch positioning piece 11 coaxial with the clutch gear 7 is fixedly arranged on the outer side of the clutch gear 7, and the clutch pin 10 extending outwards is arranged on the outer side of the clutch positioning piece 11; the bottom of the stressing hand disc 6 is sleeved at the outer end of the stressing shaft and can slide along the length direction of the stressing shaft, the stressing hand disc 6 is provided with a clutch groove matched with the clutch pin 10, and the stressing hand disc can slide towards the direction of the clutch gear to clamp the clutch pin or slide towards the opposite direction to be separated from the clutch pin.
The sprocket assembly 8 comprises a pinion 81 and a sprocket 82 which are concentric with each other, the pinion 81 is located below the clutch gear 7 and meshed therewith, preferably, the sprocket 82 and the pinion are integrally formed, and the sprocket 82 is connected with the rear wheel drive sprocket 2 through a chain 1.
In the embodiment, the diameter of the clutch positioning piece is larger than that of the clutch gear in order to be matched with the size of the bottom end of the stressing hand wheel, so that the diameter of the chain wheel below the clutch positioning piece is smaller than that of the auxiliary gear in order not to hinder the clutch positioning piece from rotating along with the stressing hand wheel; in practical application, the diameters of the clutch positioning piece and the chain wheel are not limited to fixed dimensions, and are changed along with the change of the dimension of the bottom end of the forcing hand wheel.
When the traveling mechanism works, the stressing hand disc slides inwards, the clutch groove is combined with the clutch pin, the stressing hand disc is rotated, the rear wheel shaft, the rear wheel and the rear wheel transmission chain wheel synchronously rotate through chain transmission, and when the road surface cutting operation is carried out, the cutting machine can be pushed to advance slowly in a labor-saving manner through rotating the stressing hand disc; when the cutting machine does not work, the stressing hand disc slides towards the outer end of the stressing shaft, the clutch groove is separated from the clutch pin, and the cutting machine can be manually pushed to move.
The driving device in the application can also adopt other mechanisms, such as a motor serving as a driving mechanism, a gear can be installed at the rotating shaft of the motor, and the rear wheel is driven to move forwards through a chain.
The above mentioned is only the preferred embodiment of the present invention, not as the further limitation of the present invention, and all the equivalent changes made by the contents of the specification and the drawings are within the protection scope of the present invention.
