At this time, the ground needs to be excavated to facilitate pipeline layout or shape trimming; the indoor ground ditch excavation equipment in the prior art is usually cumbersome to operate, and the excavation depth cannot be adjusted, which is inconvenient to use. Summary of the invention

[0003] In response to the above technical problems, the technical solution adopted by the present invention is: an indoor excavation device for engineering construction, including an operating mechanism for grooving and excavating the ground, the operating mechanism including an outer shell, the operating mechanism is provided with an auxiliary mechanism for assisting walking and a driving mechanism for driving the device to move, the auxiliary mechanism includes an upper slider, the upper slider is slidably installed in the outer shell, and the driving mechanism includes an inner motor, and the inner motor is fixedly installed in the outer shell.

[0006] Furthermore, two rotating wheel frames are rotatably mounted below the outer shell via a spiral spring, a lower spring is provided between the rotating wheel frame and the outer shell, and a traveling friction wheel is rotatably mounted on the rotating wheel frame.

[0008] Furthermore, two switches are fixedly installed under the shell, a switch slide rod is slidably installed in the switch, a switch contact is fixedly installed on the switch slide rod, and a switch spring is arranged between the switch contact and the switch.

[0009] In the initial state, the travel wheel and the travel friction wheel are in contact with the ground, and the cutting blade and the digging wheel are not in contact with the ground. First, move the digging device to the specified position through the steering seat and the travel wheel, hold the handrail to press the shell downward, so that the shell rotates relative to the rotating wheel frame, the lower spring is compressed, the scroll spring is twisted, and the cutting blade first contacts the ground. At this time, the switch head contacts the rotating wheel frame, and the internal motor starts to rotate. At this time, the cutting blade and the digging wheel start to rotate, and the shell is pushed to move by the handrail. First, several incisions are cut on the ground by the cutting blade to prevent the ground from being lifted up in large pieces during subsequent excavation. Then continue to press down the handrail and the shell to make the digging wheel contact with the ground. The blade digs the ground and digs up the cut ground. According to the different digging depth requirements, when the digging wheel contacts the ground, the shell continues to be pressed down, and the digging wheel and the cutting blade further drop.

[0011] When the outer shell is pressed down, the travel friction wheel remains stationary, the guide wheel is lifted up, and the upper friction wheel slides along the outer shell. At this time, the lower docking gear and the guide wheel rise, driving the middle gear and the side slider to rise, thereby driving the upper slider to slide along the outer shell through the upper rotating rod. The lower docking gear and the middle gear are always meshed, and the middle gear and the upper docking gear are always meshed, and the upper docking gear and the inner gear are always meshed.

[0031] In the initial state, the walking wheel 105 and the walking friction wheel 109 are in contact with the ground, and the cutting blade 103 and the digging wheel 106 are not in contact with the ground. First, the digging device is moved to the specified position through the steering seat 104 and the walking wheel 105, and the outer shell 101 is pressed downward by holding the handrail 102, so that the outer shell 101 rotates relative to the rotating wheel frame 107, the lower spring 108 is compressed, and the spiral spring 117 is twisted. The cutting blade 103 first contacts the ground. At this time, the switch head 110 contacts the rotating wheel frame 107, and the inner motor 301 starts to rotate. At this time, the cutting blade 103 and the digging wheel 106 start to rotate, and the outer shell 101 is pushed to move by the handrail 102. First, several incisions are cut on the ground by the cutting blade 103 to prevent the ground from being lifted up in large pieces during subsequent excavation. Then, the handrail 102 and the outer shell 101 are continued to be pressed down, so that the digging wheel 106 contacts the ground.

[0033] When the outer shell 101 is pressed down, the travel friction wheel 109 remains stationary, the guide wheel 113 is lifted up, and the upper friction wheel 112 slides along the outer shell 101. At this time, the lower docking gear 114 and the guide wheel 113 rise, driving the middle gear 207 and the side slider 206 to rise, thereby driving the upper slider 201 to slide along the outer shell 101 through the upper rotating rod 202. The lower docking gear 114 and the middle gear 207 are always meshed, and the middle gear 207 and the upper docking gear 203 are always meshed, and the upper docking gear 203 and the inner gear 204 are always meshed.

[0034] like Figure 7 , Figure 8 As shown, the driving mechanism includes a motor gear 302 fixedly mounted on the motor shaft of the inner motor 301, a transfer gear 304 is rotatably mounted in the outer shell 101, an inner conduction gear 305 is fixedly mounted on the transfer gear 304, an active transmission belt 303 is wound around the transfer gear 304 and the motor gear 302, a transmission wheel 308 is rotatably mounted in the outer shell 101, an inner and outer toothed belt 307 is wound around the transmission wheel 308 and the inner conduction gear 305, the inner and outer toothed belt 307 is meshed with the cutting gear 116, and an oblique transmission belt 306 is wound around the inner conduction gear 305 and the outer gear 205.

[0035] After the inner motor 301 is started, the inner motor 301 drives the motor gear 302 to rotate, drives the transfer gear 304 and the inner conduction gear 305 to rotate through the active transmission belt 303, drives the outer gear 205 and the inner gear 204 to rotate through the inclined transmission belt 306, the inner gear 204 drives the excavation gear 115 and the excavation wheel 106 to rotate, and the inner conduction gear 305 drives the cutting gear 116 and the cutting disc 103 to rotate through the inner and outer toothed belts 307.

[0036] The working principle of an indoor excavation device for engineering construction disclosed in the present invention is as follows: in the initial state, the walking wheel 105 and the walking friction wheel 109 are in contact with the ground, and the cutting blade 103 and the excavation wheel 106 are not in contact with the ground. First, the excavation device is moved to a specified position through the steering seat 104 and the walking wheel 105, and the handrail 102 is held to press the shell 101 downward, so that the shell 101 rotates relative to the rotating wheel frame 107, the lower spring 108 is compressed, and the volute spring 117 is twisted, and the cutting blade 103 first contacts the ground. At this time The switch head 110 contacts the rotating wheel frame 107, and the inner motor 301 starts to rotate. After the inner motor 301 is started, the inner motor 301 drives the motor gear 302 to rotate, and drives the transfer gear 304 and the inner conduction gear 305 to rotate through the active transmission belt 303, and drives the outer gear 205 and the inner gear 204 to rotate through the inclined transmission belt 306. The inner gear 204 drives the excavation gear 115 and the excavation wheel 106 to rotate, and the inner conduction gear 305 drives the cutting gear 116 and the cutting disc 103 to rotate through the inner and outer toothed belts 307. At this time, the cutting blade 103 and the digging wheel 106 begin to rotate, and the outer shell 101 is pushed to move by the handrail 102. The cutting blade 103 first cuts several cuts in the ground to prevent the ground from being lifted up in large pieces during subsequent excavation. Then, the handrail 102 and the outer shell 101 are pressed down continuously, so that the digging wheel 106 contacts the ground, and the ground is excavated by the digging blade 111 to dig up the cut ground. According to the requirements of the excavation depth, after the digging wheel 106 contacts the ground, the outer shell 101 is pressed down continuously, and the digging wheel 106 and the cutting blade 103 are further lowered. At this time, the switch slide bar 119 slides along the switch 118, and the switch spring 120 is compressed. At this time, the internal motor 301 remains started, that is, by controlling the pressure of the outer shell 101 and the handrail 102, the depth of the cutting blade 103 and the digging wheel 106 penetrating into the ground can be controlled. When the outer shell 101 is pressed down and rotated, The upper friction wheel 112 drives the travel friction wheel 109 to rotate to assist in advancing, thereby improving the speed and effect of ground cutting and excavation. After use, the lower spring 108 and the scroll spring 117 rebound, so that the shell 101 is reset, the switch head 110 is disengaged from the rotating wheel frame 107, and the inner motor 301 stops rotating. When the shell 101 is pressed down, the travel friction wheel 109 remains stationary, and the guide wheel 113 is lifted up, and the upper friction wheel 112 slides along the shell 101. At this time, the lower docking gear 114 and the guide wheel 113 rise, driving the intermediate gear 207 and the side slider 206 to rise, thereby driving the upper slider 201 to slide along the shell 101 through the upper rotating rod 202, and the lower docking gear 114 and the intermediate gear 207 are always meshed, and the intermediate gear 207 and the upper docking gear 203 are always meshed, and the upper docking gear 203 and the inner gear 204 are always meshed.
