A dicing saw 10 is provided in an embodiment of the present application. The cutting saw 10 includes a body 11, a blade 13, a power unit 12, and a drive assembly 14. The body 11 includes oppositely disposed first and second ends. The saw blade 13 is rotatably provided at a first end of the body 11. The power unit 12 is disposed at a second end of the body 11.

Wherein the blade 13 is rotated for cutting concrete obstacles or stones and the like, the power means 12 provides power to the entire cutting saw 10.

As can be seen from the above structure, when the power device 12 and the saw blade 13 are respectively located at two ends of the machine body 11, the power device 12 and the saw blade 13 are spaced apart from each other, a certain distance is provided between the power device 12 and the saw blade 13, and the transmission assembly 14 is used for transmitting the power device 12 to drive the saw blade 13 to rotate. When there is a distance between the power device 12 and the saw blade 13, the obstacle is hard to touch the power device 12 as the saw blade 13 goes deep in the cutting process, so that the overall travel of the cutting saw 10 is longer, the cutting saw 10 cuts deeper, and the overall working efficiency is higher.

It should be noted that, the power unit 12 may be an internal combustion engine or a general engine, and is not limited herein. When an internal combustion engine is used, the working effect is higher, and the power of the engine is also more sufficient.

In the embodiment of the present application, the drive assembly 14 includes a drive pulley set 140 and a drive belt 143. The driving wheel set 140 comprises a first driving wheel 141 and a second driving wheel 142 which are arranged at intervals, the first driving wheel 141 and the saw blade 13 are coaxially fixed, and the second driving wheel 142 and an output shaft of the power device 12 are coaxially fixed. At this time, the belt 143 is wound around the first and second driving wheels 141 and 142. When the power device 12 is started, the second driving wheel 142 rotates to drive the driving belt 143 and the first driving wheel 141 to rotate, and when the first driving wheel 141 rotates, the first driving wheel 141 drives the saw blade 13 to rotate to further realize cutting work.

Further, the machine body 11 includes a first housing 111 and a second housing 112, the first housing 111 extends along a first direction, the second housing 112 extends along the first direction and is fastened to the first housing 111, the first housing 111 and the second housing 112 enclose to form a receiving cavity 113, and the transmission assembly 14 is disposed in the receiving cavity 113. The first direction is an extending direction of the body 11, and a first end and a second end of the body 11 are respectively located in the first direction. The first case 111 and the second case 112 may be made of an aluminum alloy or a steel material, and are not limited thereto. When the first casing 111 and the second casing 112 are made of a rigid material, the overall structural strength is better, and the vibration-proof effect is also better. When the second casing 112 is fastened to the first casing 111, the first driving wheel 141 and the driving belt 143 are covered by the first casing 111 and the second casing 112, so that the overall structure is more attractive. The transmission component 14 is arranged in the accommodating cavity 113, so that the transmission component 14 can be better protected, the transmission component 14 is prevented from being contacted with the transmission component 14 in the high-speed running state of the saw blade 13 in the rotating process of the saw blade 13, the transmission component 14 is prevented from being damaged, and the service life of the whole structure is prolonged.

In the embodiment of the present application, the saw blade 13 is rotatably disposed at a first end of the body 11 in the first direction, the power device 12 is disposed at a second end of the body 11 in the first direction, and the power device 12 is located outside the first housing 111. The saw blade 13 and the power device 12 are arranged at intervals at this time, so that the cutting depth is increased. The closer the obstacle is to the power unit 12 as the blade 13 penetrates into the obstacle during operation of the dicing saw 10. Therefore, when the saw blade 13 and the power device 12 are arranged at intervals, a certain distance exists between the saw blade 13 and the power device 12, the whole travel of the cutting saw 10 is longer, the cutting depth is deeper in the cutting process, and the whole working efficiency of the cutting saw 10 is effectively improved.

Of course, the body 11 further includes a reinforcing cover 116, the reinforcing cover 116 is covered on the end portions of the first housing 111 and the second housing 112, the reinforcing cover 116 is located outside the second housing 112, and the reinforcing cover 116 and the power unit 12 are fixed by fixing members 117. The reinforcement cover 116 may be made of aluminum alloy or steel, but is not limited thereto. When the reinforcement cover 116 is made of steel, the overall structural strength is stronger, and the shockproof effect is better. Further, the fixing member 117 is a bolt, and is integrally formed with the power unit 12. When the reinforcement cover 116 is used to cover the outer side of the second housing 112, the second driving wheel 142 may be covered by the reinforcement cover 116, and at this time, the side wall of the dicing saw 10 is more attractive in appearance. Further, the reinforcing cover 116 also protects the second driving wheel 142 and the exposed driving belt 143, so that on one hand, the cutting saw 10 can be prevented from flying out of worn waste generated during operation, and on the other hand, the appearance of the cutting saw can be more attractive.

In the embodiment of the present application, the saw blade 13 includes two sub saw blades 131 coaxially disposed at intervals, and the sub saw blades 131 are distributed on both sides of the main body 11. When the number of sub-saw blades 131 is 2, at this time, the sub-saw blades 131 are respectively distributed at both sides of the body 11. During operation of the dicing saw 10, as the blade 13 penetrates into the obstacle, the two sub-blades 131 leave the obstacle therebetween, and at this time, the blade 13 can further penetrate into the obstacle by striking the obstacle between the two sub-blades 131 with a crow bar. Therefore, when the number of the sub-saw blades 131 is 2, the travel of the dicing saw 10 can be effectively increased by being matched with the crowbar, the cutting depth of the dicing saw 10 can be increased, and the working efficiency of the dicing saw 10 can be further improved.

In the embodiment of the present application, the transmission assembly 14 further includes a fixing plate 114, the fixing plate 114 is disposed in the body 11, and the first driving wheel 141 is rotatably disposed on the fixing plate 114.

When the first housing 111 and the second housing 112 are fastened, the fixing plate 114 is disposed between the first housing 111 and the second housing 112 and is fixed by a fastener. Further, one end of the fixing plate 114 is connected with the first driving wheel 141, so that on one hand, the connection between the first housing 111 and the second housing 112 can be more stable, and on the other hand, the fixing plate 114 can also support the first driving wheel 141, so that the saw blade 13 is prevented from rotating at a high speed in the working process of the cutting saw 10, and the stability of the saw blade 13 is prevented from being affected.

Further, the dicing saw 10 further includes a water guide 115, where the water guide 115 is disposed along the first direction and is disposed in the machine body 11, one end of the water guide 115 is connected to the first end of the machine body 11, and the other end of the water guide 115 extends out of the machine body 11. The water guide 115 extends to one end of the body 11 and may be externally connected to a water tank to provide a water source for the saw 10. When the cutting saw 10 works, the joint of the water guide 115 and the first end of the machine body 11 is provided with at least one water outlet, water is sprayed from the water outlet, dust generated during the working of the cutting saw 10 is removed, on one hand, air pollution can be avoided, on the other hand, operators can be prevented from sucking more dust, the health of the operators is guaranteed, and meanwhile, the saw blade 13 can be cooled. The water guide 115 is a hose, and when the water guide 115 is a hose, the water guide 115 extends to one end of the body 11, so that the environment adaptability is stronger, and the material of the water guide 115 is not limited.

When the water guide 115 discharges water, the saw blade 13 can throw water along with the high-speed rotation of the cutting saw 10, and the protection piece 15 can effectively prevent the water thrown out by the saw blade 13 from being sprayed on the power device 12 and the operator, and can also prevent the operator from being wetted by the water thrown out by the saw blade 13, so that the use feeling of the operator is improved. The guard 15 is movably arranged, so that the depth of cutting can be better adapted, when the depth of cutting is deeper, the barrier is abutted with the cover, and at the moment, the included angle between the guard 15 and the machine body 11 is gradually increased along with the deepening of the depth of cutting. Therefore, the protection member 15 can be continuously adjusted to the angle with the main body 11 at different cutting depths to meet the waterproof requirement at different cutting depths.

Referring to fig. 4 to 6, fig. 4 is a schematic front view of another embodiment of a dicing saw according to the present application; FIG. 5 is a schematic elevational view of a first guard of another embodiment of the dicing saw of the present application; fig. 6 is a schematic view of the back structure of a first guard of another embodiment of the dicing saw of the present application.

In another embodiment of the present application, the dicing saw 20 includes a body 21, a blade 22, a power device 23, and a first guard 24. The saw blade 22 is rotatably provided to the body 21. The power device 23 is arranged on the machine body 21 to drive the saw blade 22 to rotate. The first guard 24 is located between the saw blade 22 and the power device 23, and the first guard 24 is movably disposed on the body 21 to move between a first position and a second position, where the distance between the first guard 24 and the saw blade 22 is smaller than the distance between the first guard 24 and the saw blade 22. Wherein the first position is a position where the first guard 24 is near the saw blade 22 and the second position is a position where the first guard 24 is moved away from the saw blade 22. Further, the power unit 23 may be an internal combustion engine or a general engine. There is no limitation in this regard. When an internal combustion engine is used, the working effect is higher, and the power of the engine is also more sufficient.

As can be seen from the above structure, the first protection member 24 can adapt to the waterproof requirements at different cutting depths when movably disposed on the main body 21. When the cutting saw 20 is in the non-working state, the first protection piece 24 is located at the first position under the action of gravity or external force of the first protection piece 24, and when the cutting saw 20 starts to work, the first protection piece 24 is close to the saw blade 22, so that water sprayed by the cutting saw 20 can be prevented from being thrown onto the power device 23, and the service life of the whole structure is influenced. Of course, the water sprayed by the dicing saw 20 can be prevented from being thrown onto the operator, and the use feeling of the operator is prevented from being affected. As the cutting depth becomes deeper and deeper, the barrier abuts against the first guard 24, and the first guard 24 moves toward the second position as the cutting depth becomes deeper and deeper, so that the first guard 24 still has a good waterproof effect, and water sprayed by the cutting saw 20 is prevented from being thrown out. Also, the first guard 24 does not affect the stroke length and depth of cut of the dicing saw 20. At this time, the dicing saw 20 can satisfy both the deep dicing depth and the requirement of good waterproof effect.

The present embodiment may be implemented alone or in combination with the above embodiments.

In another embodiment of the present application, the first guard 24 includes a connecting portion 241 and a covering portion 242. The connection portion 241 is formed with a notch 2411 through which the body 21 passes, and one end of the connection portion 241 is rotatably connected to the body 21. The cover portion 242 is connected to the other end of the connecting portion 241 and covers the saw blade 22. The distance between the notch 2411 formed on the connecting portion 241 in the extending direction of the first protection member 24 is greater than the width of the main body 21, so that the first protection member 24 has a better waterproof effect when the dicing saw 20 is in the first position in the non-working state and in the state of shallow dicing depth. In other embodiments, the connecting portion 241 may also translate on the machine body 21, where the connecting portion 241 is located at the first position in a state where the dicing saw 20 is not working and in a state where the dicing depth is shallow, and the connecting portion 241 translates toward the second position as the dicing depth is deeper, so that a good waterproof effect can be achieved when any dicing depth is satisfied.

Further, the cover portion 242 is curved, and one end of the cover portion 242 away from the connecting portion 241 is curved toward the saw blade 22. At this time, when the dicing saw 20 works, the sprayed water can be effectively shielded by the shielding portion 242, so that the situation that the water sprayed by the dicing saw 20 is thrown on the power device 23 is avoided, and meanwhile, the situation that the water is thrown on the body of an operator to influence the use feeling of the operator can be effectively avoided.

In another embodiment of the present application, when the first guard 24 rotates to the first position, the connecting portion 241 abuts against the body 21, and the covering portion 242 has a gap with the saw blade 22. Under the action of gravity, when the cutting saw 20 is in an inactive state, the first guard 24 is located at the first position, at this time, the notch 2411 of the connecting portion 241 near one end of the covering portion 242 abuts against the body 21, the body 21 limits the connecting portion 241 from further approaching toward the saw blade 22, so as to prevent the connecting portion 241 from abutting against the saw blade 22 when the cutting saw 20 is started, and avoid damage to the saw blade 22 and the first guard 24. Therefore, when a gap exists between the cover portion 242 and the saw blade 22, the saw blade 22 will not abut against the cover portion 242 during rotation, so that on one hand, the operation is more stable, and on the other hand, the saw 20 will not be damaged, and further the service life of the saw 20 is prolonged.

Further, the first protection member 24 further includes an elastic member 243, the elastic member 243 is disposed at the connecting portion 241 and the rotation axis 246 of the body 21, and the elastic member 243 drives the first protection member 24 to move to the first position. Wherein the elastic member 243 is a torsion spring. The elastic member 243 is sleeved on the rotating shaft 246 of the main body 21, so that the first protecting member 24 can be stabilized at the first position under the elastic force of the elastic member 243 when the dicing saw 20 is in the inactive state or the state with a shallow dicing depth. As the cutting depth becomes deeper, the elastic force of the elastic member 243 gradually increases, so that the first protection member 24 gradually moves toward the second position. When the first guard 24 moves to the second position, the elastic force of the elastic member 243 is limited, and at this time, the obstacle cannot push the elastic member 243 to move only. Therefore, the first protection piece 24 can be effectively prevented from continuously approaching the power device 23 and damaging the power device 23 due to the action of external force of the obstacle in the moving process.

In another embodiment of the present application, the first protection member 24 further includes a rotating wheel 245, and the rotating wheel 245 is rotatably disposed at an end of the covering portion 242 away from the connecting portion 241. When the dicing saw 20 is in the rest state, the rotating wheel 245 is in a stationary state. When the dicing saw 20 starts to work, the rotating wheel 245 abuts against the obstacle along with the increase of the dicing depth, and the obstacle pushes the rotating wheel 245 to rotate, so as to drive the first guard 24 to rotate towards the second position. Further, the rotating wheel 245 can change the static friction force between the covering portion 242 and the obstacle into rolling friction force, so that the friction force is reduced, and labor is saved in the process of driving the first guard 24 to move towards the second position.

In another embodiment of the present application, the dicing saw 20 further includes a second guard 25, the second guard 25 is fixedly connected to the main body 21 and located between the saw blade 22 and the power device 23, and the extending direction of the second guard 25 is opposite to the extending direction of the first guard 24. When the dicing saw 20 is in an operating state, the thrown water is sprayed in various directions as the saw blade 22 rotates, so that the second guard 25 can effectively prevent the water thrown from below the saw blade 22 from splashing onto the power device 23 and the operator. And, the second guard 25 is fixed to the body 21 and extends in the opposite direction of the first guard 24 so that the dicing saw 20 can be more stable in operation to enhance the feeling of experience of the operator. Further, the second protection piece 25 is far away from one end of the machine body 21 and is bent towards the direction of the saw blade 22, at this time, the waterproof effect is better, the water is further prevented from splashing on the power device 23 when being thrown out, the power device 23 is short-circuited, and the water can be effectively prevented from splashing on the operator, so that the experience of the operator is affected.

Further, the dicing saw 20 further includes a limiting member 244, one end of the limiting member 244 is connected to the second protection member 25, and the other end of the limiting member 244 is rotatably connected to the rotating shaft 246 of the body 21. At this time, the second protection member 25 can be connected with the body 21 more stably by the stopper 244. The stopper 244 is rotatably connected to the rotation shaft 246, so that the first guard 24 can be rotated continuously with the depth of cut when the dicing saw 20 is in operation. Therefore, the limiting member 244 can make the connection of the second protection member 25 more stable, and can make the first protection member 24 freely rotate to adapt to different cutting depths.

Further, the body 21 includes a housing 211 and a connecting member 212, and one end of the connecting member 212 is connected to the housing, and the other end is rotatably connected to the second prevention member 25. At this time, the first guard 24 and the second guard 25 are installed more flexibly, and can be adjusted adaptively according to the environment during the operation of the dicing saw 20, so that the adaptability is stronger.

In another embodiment of the present application, the dicing saw 20 further includes a water guide 26, the water guide 26 is disposed in the main body 21, one end of the water guide 26 is connected to the main body 21 near the first position, and one end of the water guide 26 extends out of the main body 21. The water guide 26 extends to one end of the body 21 and may be externally connected to a water tank to provide a water source for the dicing saw 20. When the dicing saw 20 works, the joint of the water guide 26 and the first end of the machine body 21 is provided with at least one water outlet, water is sprayed from the water outlet, dust generated during the working of the dicing saw 20 is removed, on one hand, air pollution can be avoided, on the other hand, more dust can be prevented from being inhaled by operators, and the health of the operators is guaranteed. The water guide 26 is a hose, and when the water guide 26 is a hose, the water guide 26 extends to one end of the body 21, and the environmental adaptability is enhanced.

In another embodiment of the present application, the power device 23 and the saw blade 22 are respectively located at two ends of the machine body 21, the saw blade 22 includes two sub-saw blades 221 coaxially spaced apart, and the sub-saw blades 221 are distributed at two sides of the machine body 21. When the sub-saw blades 221 are provided in 2 numbers, the sub-saw blades 221 are respectively distributed at both sides of the body 21.
