[0027] See also Figure 1 , Figure 1 The present invention is a schematic diagram of the structure of the curbstone trenching construction in one embodiment of the present invention. The curbstone trenching construction includes a carriage 100, a lifting assembly 200 and a trenching assembly 300. The lifting assembly 200 includes a lifting seat 210 and a lifting drive 220. The lifting seat 210 is slidably arranged on the carriage 100 along the vertical direction. The lifting drive 220 drives the lifting seat 210 to slide relative to the carriage 100. The trenching assembly 300 includes a milling disc 310 and a trenching drive 320. The milling disc 310 is rotatably installed on the lifting seat 210. The trenching drive 320 drives the milling disc 310 to rotate relative to the lifting seat 210.

[0028] In this embodiment, the carriage 100 is first placed at the position where trenching is to be carried out, and the milling disc 310 can be driven to rotate by the trenching driving member 320 to carry out trenching by using the rotating milling disc 310. When the trenching depth needs to be adjusted, the lifting seat 210 can be driven to slide in the vertical direction by the lifting driving member 220, thereby adjusting the depth of the milling disc 310 embedded in the soil layer, and then adjusting the trenching depth of the curb trenching device.

[0029] In some embodiments, the lifting drive member 220 includes a lifting motor 221 and a screw rod 222. The lifting seat 210 is provided with a wire hole (not shown in the figure) in the vertical direction. The screw rod 222 is threadedly connected to the wire hole (not shown in the figure). The lifting motor 221 is connected to the screw rod 222 to drive the screw rod 222 to rotate, thereby driving the lifting seat 210 to slide in the vertical direction.

[0030] In this embodiment, the lifting motor 221 drives the screw rod 222 to rotate. Since the screw rod 222 and the threaded hole (not shown in the figure) are threadedly connected to each other, the rotating screw rod 222 can drive the lifting seat 210 to slide in the vertical direction, thereby adjusting the height of the milling disc 310.

[0031] In some of the embodiments, the lifting drive member 220 further includes a transmission shaft 223 , one end of which is directly connected to the lifting motor 221 , and the other end of which is transmission-connected to the screw rod 222 to drive the screw rod 222 to rotate.

[0032] In this embodiment, due to the installation space limitation in the carriage 100 , the distance between the lifting motor 221 and the screw rod 222 is relatively far, so the lifting motor 221 is driven via the transmission shaft 223 , thereby driving the screw rod 222 to rotate.

[0033] In some of the embodiments, the lifting assembly 200 further includes a scale 230 and a nut 240 , the nut 240 is slidably disposed in the carriage 100 along a vertical direction, and the nut 240 is threadedly connected to the screw rod 222 , the scale 230 is connected to the nut 240 so as to slide along with the scale 230 and the nut 240 .

[0034] In this embodiment, since the nut 240 is slidably disposed on the carriage 100 and is also threadedly connected to the screw rod 222, when the screw rod 222 rotates, the nut 240 will slide relative to the carriage 100, thereby driving the scale 230 to slide, so that the height change of the lifting seat 210 can be known through the scale of the scale 230.

[0035] In some embodiments, the carriage 100 includes a body 110 and an armrest 120 , a lift seat 210 is slidably disposed on the body 110 , and the armrest 120 is installed at one end of the body 110 that is not closer to the lift seat 210 .

[0036] In this embodiment, the operator can hold the handrail 120 to adjust and drag the vehicle body 110 to move, thereby changing the moving trajectory of the vehicle body 110 to further adjust the trenching direction.

[0037] In some of the embodiments, the carriage 100 further includes a track 130, a transmission member 140 and a plurality of wheels 150, wherein the plurality of wheels 150 are rotatably mounted on the vehicle body 110, the track 130 surrounds the plurality of wheels 150, one end of the transmission member 140 is transmission-connected to the trenching drive member 320, and the other end thereof is transmission-connected to at least one wheel 150, so as to drive the wheel 150 to rotate through the trenching drive member 320.

[0038] In this embodiment, the trenching driving member 320 drives the wheel 150 to rotate via the transmission member 140, and then drives the track 130 to rotate through the wheel 150. The rotating track 130 can drive the vehicle body 110 to move relative to the ground.

[0039] Any implementation of the trenching drive 320 that can drive the milling disc 310 to rotate is feasible. In some embodiments, the trenching drive 320 includes a trenching motor 321, which is installed on the lifting seat 210 and directly connected to the milling disc 310 to drive the milling disc 310 to rotate relative to the lifting seat 210.

[0040] In some of the embodiments, the transmission member 140 includes a transmission flexible shaft 141, a transmission belt 142 and a reduction gearbox 143 which are sequentially connected, the transmission flexible shaft 141 is transmission-connected to the trenching motor 321, and the reduction gearbox 143 is transmission-connected to the wheel 150.

[0041] In this embodiment, the transmission member 140 includes a transmission flexible shaft 141, a transmission belt 142 and a reduction box 143 which are sequentially connected. Since the lifting seat 210 slides relative to the vehicle body 110, the transmission flexible shaft 141 can adapt to the position change between the lifting seat 210 and the vehicle body 110.

[0042] In some of the embodiments, the curb trenching device also includes a sprinkler assembly 400, which includes a water tank 410, a water pump 420 and a nozzle 430. The water tank 410 is used to store water, and the nozzle 430 is installed on the carriage 100 and faces the milling disc 310. One end of the water pump 420 is connected to the water tank 410, and the other end thereof is connected to the nozzle 430 to send the water pressure in the water tank 410 to the nozzle 430.

[0043] In this embodiment, the water tank 410 is used to pressurize water toward the nozzle 430 through the water pump 420 , and the water flow sprayed by the nozzle 430 impacts the milling disc 310 , so that the milling disc 310 is cooled by the water flow.

[0044] In some embodiments, the milling disc 310 includes a disc body 311 and a plurality of latching teeth 312 . The disc body 311 is rotatably mounted on the lifting seat 210 , and the plurality of latching teeth 312 surround the outer circumference of the disc body 311 in a circumferential direction.

[0045] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0046] First, the carriage 100 is placed at the position where the trench is to be opened. The trenching drive 320 drives the milling disc 310 to rotate, and the milling disc 310 can be used to open the trench. The water tank 410 is used to press water to the nozzle 430 through the water pump 420, and the water flow sprayed by the nozzle 430 impacts the milling disc 310, so that the water flow is used to cool the milling disc 310. When the trenching depth needs to be adjusted, the lifting motor 221 drives the screw rod 222 to rotate. Since the screw rod 222 and the thread hole (not shown in the figure) are threadedly connected to each other, the rotating screw rod 222 can drive the lifting seat 210 to slide in the vertical direction, and then the height of the milling disc 310 can be adjusted, and the depth of the milling disc 310 embedded in the soil layer is adjusted, and then the trenching depth of the curb trenching device is adjusted.

[0047] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
