DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0019] The current excavation device does not have a dust removal structure when in use, which causes a large amount of dust to spread in the surrounding air during excavation work. When workers inhale too much dust for a long time, it will cause serious damage to the human body, and even endanger life safety in severe cases, thus bringing inconvenience to the workers;

[0020] In view of this, the utility model provides a tunneling device for small underground engineering construction. Through the cooperation of the machine body, the tunneling mechanism and the dust reduction device, it can automatically perform spray dust reduction during tunneling, thereby preventing a large amount of dust from spreading into the surrounding environment. Therefore, the impact of dust on the workers can be reduced, thereby ensuring the work safety of the workers and improving the work comfort of the workers.

[0021] Embodiment 1: Figure 1 , 2 , 3 and 4 show that a small-scale underground engineering construction excavation device includes a machine body 1, a horizontal plate 9 is arranged above the machine body 1, a mounting plate 4 is installed on one side of the top of the horizontal plate 9, and an excavation mechanism 5 is installed on one side of the mounting plate 4. The small-scale underground engineering construction excavation device also includes: a dust reduction device 2, which is arranged above the horizontal plate 9; a slag cleaning device 3, which is arranged below the horizontal plate 9; wherein the dust reduction device 2 can spray dust reduction on the dust generated by the excavation mechanism 5 during excavation, and the slag cleaning device 3 can transport the soil and the like generated by the excavation mechanism 5 during excavation;

[0022] In the specific implementation process, it is worth pointing out that the excavation mechanism 5 is the existing technology of the current excavator, and this case has not improved or innovated its structure, so it will not be described in detail. The dust suppression device 2 can spray water mist during the excavation work, thereby preventing a large amount of dust from spreading into the surrounding air. The slag cleaning device 3 can transport the soil generated during the excavation to prevent the soil from accumulating in front of the excavation device for small underground engineering construction and affecting its travel route.

[0023] Furthermore, the outer wall of the excavation mechanism 5 is sleeved with a protective shell 6, and one side of the protective shell 6 is detachably connected to the outer wall of the mounting plate 4;

[0024] In the specific implementation process, it is worth pointing out that the protective shell 6 can isolate and protect the excavation mechanism 5 to prevent damage to the excavation mechanism 5 when the upper part collapses. At the same time, the protective shell 6 should reserve a cavity for the excavation mechanism 5 to adjust the angle, thereby ensuring that the protective shell 6 does not cause spatial interference to the excavation mechanism 5. The design of the cavity can be selected according to actual use requirements, and no further details will be given here.

[0025] Furthermore, the top of the machine body 1 is detachably connected with a plurality of hydraulic cylinders 8, and the model of the hydraulic cylinders 8 is not specifically limited, and can meet the use requirements. The output ends of the plurality of hydraulic cylinders 8 are detachably connected to the bottom of the transverse plate 9, and the outer wall of the mounting plate 4 is installed with a reinforcing plate 7 fixedly connected to the top of the transverse plate 9;

[0026] In the specific implementation process, it is worth pointing out that the hydraulic cylinder 8 can change the position height of the cross plate 9, and then adjust the position height of the excavation mechanism 5, so as to achieve excavation work at different heights;

[0027] Specifically, when using the tunneling device for small underground engineering construction, the staff first moves the tunneling device for small underground engineering construction to a suitable position, and then uses the tunneling mechanism 5 to carry out tunneling and excavation. At the same time, the staff turns on the external power supply of the dust reduction device 2. At this time, the dust reduction device 2 can spray water mist into the surrounding air to complete the dust reduction work. Then the staff turns on the external power supply of the slag cleaning device 3. At this time, the slag cleaning device 3 can transport the soil and the like generated by the tunneling mechanism 5 during excavation.

[0028] Embodiment 2: By Figure 1 and 2 It can be seen that the dust suppression device 2 includes: a water tank 201, which is installed on the top of the horizontal plate 9 and is fixedly connected to one side of the mounting plate 4; a water pump 202, the model of which is not specifically limited, and can be detachably connected to the lower part of the inner part of the water tank 201 as long as it meets the use requirements; a conduit 203, which is connected to the output end of the water pump 202 and extends to the upper side of the protective shell 6; a fixed pipe 204, which is sleeved on the outer wall of the conduit 203 and is fixedly connected to the outer wall of the protective shell 6; a water supply and drainage pipe 205, which is arranged at the lower side of the water tank 201; wherein the water pump 202 can extract the water source inside the water tank 201, then transport it through the conduit 203, and finally spray it to the excavation position of the excavation mechanism 5;

[0029] In the specific implementation process, it is worth pointing out that an atomizing nozzle should be installed at the end of the conduit 203, so that the water source transported by the conduit 203 can be atomized and then sprayed into the surrounding air. The water pump 202 can pump out the water source inside the water tank 201, and then transport it through the conduit 203, and finally spray the water mist into the outside air.

[0030] Specifically, based on the above-mentioned embodiment 1, when spray dust reduction is required, the staff turns on the external power supply of the water pump 202. At this time, the water pump 202 can draw out the water source inside the water tank 201, and then transport it through the conduit 203, and finally spray it into the surrounding air through the atomizing nozzle at the end of the conduit 203, thereby achieving dust reduction.

[0031] Embodiment 3: By Figure 1 , 3 As can be seen from Figures 4, the slag cleaning device 3 includes: a guide hopper 301, installed on one side of the outer wall of the machine body 1; a conveyor belt 302, installed inside the machine body 1; wherein the guide hopper 301 can guide the excavated soil, and then use the conveyor belt 302 to transport it;

[0032] In the specific implementation process, it is worth pointing out that the guide hopper 301 can collect the soil excavated by the excavation mechanism 5, and then transport it through the conveyor belt 302;

[0033] Specifically, based on the above-mentioned embodiments 1 and 2, the soil excavated by the excavation mechanism 5 falls into the interior of the guide bucket 301 due to the action of gravity, and then slides to the bottom of the guide bucket 301. At this time, the staff turns on the external power supply of the conveyor belt 302, and the conveyor belt 302 can then transport the soil, etc.
