Problems solved by technology
The excavating device described in this patent is operated by two people to complete the excavation, but it is portable and needs to be manually lifted for use. Therefore, only some small power devices can be used, and some thicker or deeper pole pits cannot be excavated due to power problems. , but also not suitable for hard soil or sandy soil

Embodiment 1
[0046] refer to Figure 1-Figure 4 , The rod pit excavation device for power engineering provided in this embodiment includes a vehicle frame 1 , a driving mechanism 2 , a deceleration mechanism 3 , a transmission mechanism 4 and an excavating mechanism 5 .
[0047] The vehicle frame 1 adopts a steel frame structure, the lower part is an inverted triangular support structure, and a wheel 11 is respectively arranged on both sides of the lower part; vertical support rods 12 are vertically fixed on both sides of the upper part of the front end of the vehicle frame 1, and two vertical support rods A horizontal connecting rod 13 is fixedly connected to the top of the rod 12, and the horizontal connecting rod 13 is a cylindrical rod. The vehicle frame 1 of this embodiment is welded by channel steel, of course, it can also be welded by other profiles such as square steel and angle steel in actual implementation.
[0048] The driving structure 2 is fixedly arranged on the upper part ...
Embodiment 2
[0058] refer to Figure 5 Compared with Embodiment 1, the excavating mechanism 5 of the pole pit excavation device for electric power engineering provided by this embodiment has been improved as follows: the bottom of the spiral piece 52 is provided with bucket teeth 55, and the bottom end of the central rod 51 is provided with an auger bit 56 .
[0059] The bucket teeth 55 are fixed on the bottom edge of the helical blade 52 and are shovel-shaped and made of wear-resistant alloy; the auger bit 56 is fixed on the bottom of the central rod 51 and is a conical auger bit.
[0060] The auger bit 56 of the excavating mechanism 5 in this embodiment can play a positioning role, and at the same time, it can loosen the soil layer after excavation, so that the bucket teeth 55 and the spiral blades 52 can excavate the soil layer. The bucket teeth 55 are made of wear-resistant materials, which can not only improve the excavation efficiency, but also protect the spiral blade 52 .

Abstract
The invention provides a pole pit excavation device for electric power engineering, and belongs to the technical field of electric power construction. The pole pit excavation device comprises a frame, a driving mechanism, a speed reducing mechanism, a transmission mechanism and an excavating mechanism; the upper part of the front end of the frame is provided with a horizontal connecting rod for connecting two sides of the frame, and two sides of the bottom are provided with wheels; the driving mechanism is fixedly arranged at the rear end of the frame and is used for outputting power; the speed reducing mechanism is fixedly arranged at the rear end of the frame, the input end of the speed reducing mechanism is fixedly connected with the output end of the driving mechanism, and the speed reducing mechanism is used for reducing the output rotating speed of the driving mechanism and adjusting the output rotating direction of the driving mechanism; the input end of the transmission mechanism is fixedly connected with the output end of the speed reducing mechanism, the output end of the transmission mechanism is in transmission connection with the excavating mechanism, and the transmission mechanism is used for driving the excavating mechanism to rotate; and the excavating mechanism is of a spiral structure, the top end of the excavating mechanism is rotationally connected with the horizontal connecting rod, and the excavating mechanism is used for excavating soil layers. According to the pole pit excavation device for electric power engineering, an internal combustion engine is adopted as a power system, and the device is suitable for various soil layers such as a loess layer, a clay layer, a frozen soil layer and a gravel soil layer.
Description
technical field [0001] The invention belongs to the technical field of electric power construction, and in particular relates to a pole pit excavation device for electric power engineering. Background technique [0002] The pole plays the role of supporting the overhead wire in the overhead transmission line. The pole needs to be planted on the ground, and the pole hole needs to be excavated before erection. At present, digging pits is generally completed by manpower using tools such as shovels. During manual excavation, the range of soil taken is wide, and a lot of earth needs to be excavated and backfilled, which is time-consuming and laborious, and the construction efficiency is slow. At the same time, manual excavation requires a large area to be stacked The excavated soil is likely to cause damage to the young crops of farmers during field construction; and the manual excavation of the soil layer is easy to loosen and collapse, causing the pole to be unstable and bringi...
