Technical Field

[0001] This utility model relates to the technical field of road maintenance joint cutting machines, and more specifically, to a road maintenance joint cutting machine. Background Technology

[0002] The road maintenance joint cutting machine is an important tool for road maintenance and construction. It is mainly used to cut fine joints on cement and asphalt roads. It uses diamond saw blades, which can cut quickly and produce clean and beautiful cuts. At the same time, it can cut the steel bars in the concrete. The machine is powerful, easy to move, and simple to operate, making it an indispensable construction machine in concrete road construction projects.

[0003] For example, Chinese Patent Publication No. CN202121836430.9 discloses a user-friendly road surface maintenance cutting machine, including a push handle, a connecting plate fixedly connected to the surface of the push handle, a throttle cable fixedly installed on the surface of the connecting plate, a water tank fixedly connected to one end of the connecting plate, a water inlet fixedly installed on the surface of the water tank, a cutting depth crank fixedly installed on the surface of the water tank, a vehicle frame fixedly connected to the lower surface of the water tank, wheels fixedly installed on the lower surface of the vehicle frame, an engine fixedly installed on the upper surface of the vehicle frame, a fuel tank fixedly installed on the upper surface of the engine, and a muffler fixedly installed on one side of the fuel tank. This utility model discloses a user-friendly road surface maintenance cutting machine that, through the design of a cutting guard, protects against external damage during use, preventing the cutting blade from breaking and injuring the user. The baffle effectively blocks dust, preventing users from inhaling large amounts of dust and causing lung injury.

[0004] However, in the above technical solution, the joint cutter is one of the key pieces of equipment in road maintenance operations, responsible for precisely cutting the road surface to facilitate subsequent repair and maintenance work. However, in the above technical solution, although the baffle and lifting plate on the cutting component can effectively block dust and prevent dust from escaping, they also block the gravel generated during the cutting process, preventing the gravel from leaving the cutting component. As the cut extends, the gravel inside the cutting component will accumulate more and more, making it very easy for the gravel to come into contact with the cutting blade of the cutting component, causing the gravel to affect the cutting blade of the cutting component, thereby affecting the cutting of the cutting component. Utility Model Content

[0005] The main objective of this invention is to provide a road maintenance joint cutting machine that can effectively solve the problem in the background art where the joint cutting machine, as one of the key pieces of equipment in road maintenance operations, is responsible for precisely cutting the road surface to facilitate subsequent repair and maintenance work. However, in the above-mentioned technical solutions, although the baffles and lifting plates on the cutting components can effectively block dust and prevent it from escaping, they also block the gravel generated during cutting, preventing the gravel from leaving the cutting components. As the cut extends, the gravel inside the cutting components will accumulate more and more, making it easy for the gravel to come into contact with the cutting blade of the cutting components, causing the gravel to affect the cutting blade of the cutting components, thereby affecting the cutting of the cut.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a road maintenance joint cutting machine, including a joint cutting machine body, a cutting component is provided on the joint cutting machine body, a material passage trough is provided on one side of the cutting component, a material storage trough is provided on one side of the material passage trough, an arc-shaped groove is provided on one side above the material storage trough, a conveyor belt is provided in the material storage trough, a plurality of baffles are fixedly provided on the conveyor belt, and a timer is provided on one side of the conveyor belt.

[0007] Preferably, the material conveying trough and the material storage trough are interconnected, and the material storage trough and the arc-shaped trough are interconnected.

[0008] Preferably, the baffle includes a baffle body, and a plurality of first grooves and a plurality of second grooves are provided on the side of the baffle body away from the conveyor belt.

[0009] Preferably, both the first and second slides are slidably provided with baffles, and springs are fixedly provided on the baffles.

[0010] Preferably, the first and second slides are arranged alternately.

[0011] Preferably, one side of the spring is fixedly connected to the baffle body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) During the moving cutting process, as the main body of the cutting machine moves, the gravel generated by the cutting will enter the storage tank along the feed chute. The baffles intercept the gravel entering the storage tank, thereby temporarily storing the gravel in the storage tank. At the same time, the baffles block the dust entering the storage tank and the arc groove, preventing the gravel and dust from flowing out of the storage tank and the arc groove. Then, the conveyor belt is periodically started by the timer. The conveyor belt drives the baffles, and some of the gravel in the storage tank is discharged to the outside of the storage tank through some of the baffles. Other baffles continue to block the remaining gravel in the storage tank, thereby preventing the gravel from accumulating too much in the cutting part and affecting the cutting of the cutting part.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2 As shown, a road maintenance joint cutting machine includes a joint cutting machine body 1, a cutting component 2 is provided on the joint cutting machine body 1, a material passage trough 3 is provided on one side of the cutting component 2, a material storage trough 8 is provided on one side of the material passage trough 3, an arc-shaped groove 4 is provided on one side above the material storage trough 8, a conveyor belt 5 is provided in the material storage trough 8, a plurality of baffles 6 are fixedly provided on the conveyor belt 5, and a timer 7 is provided on one side of the conveyor belt 5.

[0020] like Figure 3As shown, in another embodiment of the present invention, the baffle 6 includes a baffle body 601, and a plurality of first grooves 602 and a plurality of second grooves 603 are provided on the side of the baffle body 601 away from the conveyor belt 5.

[0021] Both the first slide groove 602 and the second slide groove 603 are slidably provided with a stop post 604, and a spring 605 is fixedly provided on the stop post 604.

[0022] When the conveyor belt 5 is not running, the baffle body 601 and the staggered baffle posts 604 block the gravel and dust in the storage trough 8 and the arc-shaped trough 4, preventing the gravel and dust from flowing out of the storage trough 8 and the arc-shaped trough 4. The baffle posts 604 can be elastically extended and retracted by the spring 605, so that when the baffle posts 604 enter the arc-shaped trough 4, they will stick tightly to the inner wall of the arc-shaped trough 4, thereby further blocking the dust in the arc-shaped trough 4 and preventing the dust in the arc-shaped trough 4 from flowing out from the baffle 6. It can also make the baffle posts 604 located in the storage trough 8 stick tightly to the ground, thereby preventing the gravel and dust from flowing out from the gap between the ground and the baffle posts 604.

[0023] The working principle of this type of road maintenance joint cutting machine:

[0024] In operation, the main body 1 of the cutting machine first moves the cutting component 2 to cut the road surface. During the cutting process, as the main body 1 moves, the gravel produced by the cutting will enter the storage tank 8 along the feed chute 3. The baffle 6 intercepts the gravel entering the storage tank 8, thus temporarily storing the gravel in the storage tank 8. At the same time, the baffle 6 blocks the dust entering the storage tank 8 and the arc-shaped groove 4, preventing the gravel and dust from flowing out of the storage tank 8 and the arc-shaped groove 4. Then, the timer 7 periodically starts the conveyor belt 5, which drives the baffle 6. Some of the gravel in the storage tank 8 is discharged to the outside of the storage tank 8 through the baffle 6, and the remaining gravel in the storage tank 8 is blocked by the other baffles 6, thus preventing the gravel from accumulating too much in the cutting component 2 and affecting the cutting of the cutting component 2.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
