Embodiment 1

[0032] see Figure 1-Figure 9, a low-disturbance foundation pit leveling machine, including a two-wheel crawler vehicle 1, a traction system 2, a soil cutting wheel 3, a soil storage box 4, and a soil accumulation transmission device 5, characterized in that: the two-wheel crawler vehicle 1 is connected to the soil storage box 4 through the traction system 2, the soil cutting wheel 3 is installed at the front lower part of the soil storage box 4, and the soil accumulation transmission device 5 is installed at the rear lower part; Electric drive, providing forward traction; two-wheel crawler vehicle 1 is universally connected to traction system 2; the traction force of two-wheel crawler vehicle 1 is transmitted to soil storage box 4 through traction system 2, driving soil storage box 4 forward; traction system 2 Connect the central point of the front end of the soil storage box 4; the shape of the hollowed out front half of the soil storage box 4 is 3 / 4 sector, and the 1 / 4 gap ...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0035] 2. The two-wheeled tracked vehicle 1 is a two-wheeled independent power tracked vehicle, comprising a front active track wheel 11, a tracked vehicle beam 12, a track 13 and a rear driven track wheel 14; the front active track wheel 11 is an electric drive wheel, and the rear The driven track wheel 14 has no power, and the speed of the left and right driving wheels is controlled to be different so that it can turn freely; the tracked vehicle beam 12 is a bridge connecting the left and right track wheels, and the middle part is welded with a universal rotating slipknot 21, which is used to transmit traction and change direction The crawler belt 13 is a part directly in contact with the ground, because the crawler belt is flatter than the common tire, and the ground contact part is always on the same level, so the soil layer contacted by the crawler belt 13 and the soil ...

Embodiment 3

[0041] Such as Figure 1-9 As shown, the embodiment provides a low-disturbance foundation pit leveling machine, which includes a two-wheel crawler vehicle 1 , a traction system 2 , a soil cutting wheel 3 , a soil storage box 4 and a soil accumulation conveying device 5 .

[0042] The two-wheeled crawler vehicle 1 is driven by electricity and provides forward traction for the whole device. The two-wheeled crawler vehicle 1 is connected to the traction system 2 through the universal conversion slipknot 21; the traction force of the two-wheeled crawler vehicle 1 is transmitted to the soil storage box through the traction system 2 4. Drive the soil storage box 4 forward; the traction system 2 uses two drawbars 22 to connect the two ends of the central fixed shaft 33, and the hydraulic telescopic rod 23 is connected to the central point of the front end of the soil storage box 4; the front half of the soil storage box 4 is the front box body 41, the shape of the hollowed out inside...

Abstract

The invention discloses a foundation pit leveling machine with low disturbance degree. It includes a front-mounted two-wheeled crawler, which can be steered freely. The beam of the two-wheeled crawler is equipped with a universal rotating hinge, and the hydraulic telescopic rod and the two traction rods form a triangular cone. When the hydraulic telescopic rod is extended and retracted The height of the two-wheeled crawler can be changed to change the soil cutting depth; the soil cutting wheel has five soil cutting blades, and the soil cutting blades are arc-shaped. When cutting soil, the soil cutting wheel must rotate counterclockwise. Throw it into the rear box; the bottom of the rear box is a funnel cavity, which is convenient for soil accumulation. The soil leveling guide wheel is a cylindrical roller installed at the bottom of the soil storage box, which flattens and compacts the cut soil, and reduces friction when moving forward; Transport out of the foundation pit. The invention reduces the foundation pit leveling cost and improves the efficiency, and is used to solve the problems of slow, uneven, easy disturbance, easy over-excavation and the like of the existing foundation pit manual excavation.

Description

technical field [0001] The invention relates to the excavation of foundation soil for building foundations, in particular to a low-disturbance leveling machine for foundation pits. Background technique [0002] The excavation of the foundation pit needs to determine the excavation depth according to the design regulations. Generally, large-scale foundation pits are usually excavated by large-scale machinery. In order to prevent the base soil from being disturbed and the soil structure damaged, large-scale machinery should not be dug directly to the bottom of the pit. According to the type of machinery, 200-300mm should be left above the base level. , and use manual shoveling and repairing before the foundation construction. Features of manual excavation: It can avoid large-scale mechanical disturbance of the original structure of the bearing layer, thereby affecting the characteristic value of the bearing capacity of the bearing layer; it can avoid the undisturbed soil of t...
