[0030] Reference Figure 1-5The utility model provides a municipal construction slotting machine with a protective structure: it includes a base 1, a cylinder 2 is fixedly installed on the top of the base 1, a bracket 3 is fixedly connected to the output end of the cylinder 2, the bottom end of the bracket 3 movably penetrates the base 1 and extends to the outside, a slotting knife 4 is rotatably connected to the bracket 3, a driving assembly is arranged on the bracket 3, a protective frame 5 is slidably connected to the bracket 3, both sides of the protective frame 5 are fixedly connected to connecting buckets 6, and the opposite sides of the two connecting buckets 6 are fixedly connected to hoses 7, a filter box 8 is fixedly connected to the top of the base 1, a filter plate 11 is arranged inside the filter box 8, one side of the filter box 8 is fixed to one end of one of the hoses 7 The filter box 8 is fixedly connected, and a fan 9 is arranged on the other side. The blowing end of the fan 9 is fixedly connected with one end of another hose 7, and the suction end of the fan 9 is connected with the filter box 8. A shock absorbing assembly is arranged on the base 1, and four universal wheels 10 are arranged at the bottom of the base 1. Through the coordinated use of structures such as the base 1, the damper 19, the spring 20 and the universal wheel 10, the vibration generated by the device can be absorbed and buffered, which not only reduces the vibration generated by the device when grooving the road, but also improves the service life of the device. At the same time, it can reduce the jitter generated during movement, protect the grooving knife 4 during work, and avoid it from being offset and tilted during work to affect the quality of grooving.

[0031] A limiting rod 12 is fixedly connected to the top of the base 1. Through the setting of the limiting rod 12, one of the hoses 7 can be limited to prevent it from hindering the downward movement of the motor 15. A plurality of balls 13 are embedded in the bottom of the protective frame 5. Through the setting of the balls 13, the friction between the protective frame 5 and the road can be reduced after it abuts against the road, so that the device can perform mobile grooving work. A plurality of ventilation slots 21 are opened on the front and back of the protective frame 5. A plurality of wind guide plates 22 are fixedly connected to the front and back of the protective frame 5. Through the setting of the ventilation slots 21 and the wind guide plates 22, during the operation of the device, when the wind in the external environment is large and the wind direction is consistent with the direction of the gas blown out from the blowing end of the fan 9 through the corresponding hose 7 and the connecting bucket 6, the external wind can flow to the inside of the protective frame 5, further improving the circulation speed of the gas inside the protective frame 5 and improving the heat dissipation effect of the grooving knife 4.

[0032] Two springs 14 are fixedly connected to the bottom of the base 1, and the bottom ends of the two springs 14 are fixedly connected to the top of the protection frame 5. When the telescopic end of the cylinder 2 is not retracted and the protection frame 5 is not moved down to abut the ground, the spring 14 is in a compressed state.

[0033] The driving assembly includes a motor 15 fixedly mounted on one side of the bracket 3, the output end of the motor 15 is fixedly connected to a rotating shaft 16, a transmission mechanism 17 is transmission-connected between the outer surface of the rotating shaft 16 and the slotting knife 4, and a shielding frame 18 is fixedly connected to the side of the bracket 3 away from the motor 15. By setting the shielding frame 18, the transmission assembly can be shielded to prevent stones generated by slotting from splashing into the transmission mechanism 17 and affecting its use.

[0034] The shock absorbing assembly includes four dampers 19, which are fixedly connected to the bottom of the base 1. The outer surfaces of the four dampers 19 are sleeved with springs 20, and the other ends of the four dampers 19 are fixedly connected to the top ends of the four universal wheels 10 respectively.

[0035] Working principle: When working, the device is moved to the position where the road is to be grooved, and then the motor 15 is started, so that its output end drives the rotating shaft 16 to rotate, and under the transmission action of the transmission mechanism 17, the groove cutter 4 rotates, and then the cylinder 2 is started to shrink its telescopic end, driving the bracket 3, the motor 15, the transmission mechanism 17, the shielding frame 18, the groove cutter 4 and the protective frame 5 to move downward synchronously, so that the two springs 14 are stretched, and a number of balls 13 are in contact with the road, and then the protective frame 5 is used to make the groove. The groove cutter 4 continues to move downward to cut the road, and the stones splashed during the road cutting can be intercepted by the protection frame 5 to prevent them from splashing around and accidentally injuring pedestrians passing by the device. At the same time, the telescopic end of the cylinder 2 continues to slowly contract to make the groove cutter 4 move downward, and the groove depth can be adjusted. At the same time, when the groove cutter 4 moves downward, the protection frame 5 slides on the bracket 3 under the abutment of the road to prevent it from hindering the groove cutter 4 from moving downward to cut the road;

[0036] When the grooving knife 4 and the protection frame 5 are moved down, the road grooving and shielding protection work are carried out respectively, and the fan 9 can be started at the same time, so that the output end of the fan can be blown to blow the gas into the protection frame 5 through the corresponding hose 7 and the connecting bucket 6, and the dust generated by the road grooving is blown to another connecting bucket 6. At the same time, the suction end of the fan 9 extracts the gas in the filter box 8 to generate negative pressure, so that the hose 7 and the corresponding connecting bucket 6 connected to it can flow into the filter box 8, and then the gas inside the protection frame 5 can flow into the filter box 8 through the connecting bucket 6 and the hose 7, so that the gas inside the protection frame 5 can circulate quickly, and the grooving knife 4 during the work process can be blown to cool down. At the same time, the gas can carry the dust inside the protection frame 5 during the circulation process, and gather it in the filter box 8 under the interception and filtration action of the filter plate 11.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
