The fixed frame 1 is provided with a vertical sliding column 21, and the sliding column 21 is of a cylindrical rod-shaped structure and is used for mounting the engine base 4.

The engine base 4 is provided with a vertical sliding sleeve 20, and the sliding sleeve 20 is sleeved on a sliding column 21 of the fixed frame 1 and can slide up and down along the sliding column 21 to move up and down. And a convex plate 8 is also arranged on the engine base 4.

The engine 3 sets up on engine base 4, and engine 3 below is connected with screw rod 5, screw rod 5 includes cylinder and helicla flute, and the relation of connection between helicla flute and the cylinder is that the cylinder surface is cut there is the helicla flute, and screw rod 5 rotates and can drive the helicla flute rotatory. The soil drilling process is that the engine base 4 moves downwards along the sliding column 21 on the fixed frame to drive the engine 3 and the screw 5 to move towards the ground of the position to be drilled, the engine 3 drives the screw 5 to rotate to drill soil, and the screw 5 rotates to enable the spiral groove in the screw 5 to take out the soil, so that pit digging processing on the ground is achieved.

The reset spring 6 is used for resetting the engine base 4, the upper end of the reset spring 6 is connected with the fixed frame 1, and the lower end of the reset spring 6 is connected with the engine base 4. When the soil drilling is started, the return spring 6 is extended by applying a downward tensile force to the return spring 6 by means of the gravity of the engine base 4, the engine 3 and the screw 5 and a downward pressure applied to the engine base 4, and after the screw 5 contacts the ground and the soil drilling process is finished once, the screw 5 stops rotating, and the return spring 6 applies an upward tensile force to the engine base 4 to return the engine base 4.

The roller 2 is arranged at the lower end of the fixed frame 1 and can integrally walk through the roller 2 pushing device.

Push down drive arrangement 7 sets up on fixed frame 1 and is located one side of traveller 21 on fixed frame 1 for exert down force to flange 8 on engine base 4, including lift drive portion, lift drive portion and lift portion all set up on fixed frame 1, and lift portion can be on fixed frame 1 and do elevating movement, and lift drive portion is used for exerting down force to the lift portion, makes the lift portion move downwards, and when the lift portion moved to the lug position department on engine base 4, continues downstream along with the lift portion, exerts decurrent pressure to engine base 4, realizes exerting down force to screw rod 5 that sets up on engine base 4 indirectly, solves and causes the difficult technical problem of boring to the ground because of soil hardening problem, promotes and bores native effect. In addition, in a working scene that the soil is soft, the downward pressure can be applied to the convex plate 8 on the fixed base by using both hands or feet manually, so that the screw rod 5 is driven to press downward.

As a preferred technical scheme of the utility model, the lift drive portion that pushes down drive arrangement 7 includes cylinder 11, cylinder 11 passes through the vertical upper portion that sets up on fixed frame 1 of cylinder block, the lift portion includes stand 9, lift post 10, stand 9 is cylindricality shaft-like structure, and vertical the setting on fixed frame 1 of stand 9, the lower extreme of stand 9 and fixed frame 1's lower extreme are connected and stand 9 is located the below of cylinder 11, lift post 10 is below open-ended cylindricality tubular structure, and on stand 9 was located to lift post 10 cover, be equipped with bellied clamp plate 13 on the lower part side surface of lift post 10, the length of clamp plate 13 is greater than the distance between the flange 8 on stand 9 and the engine 3 fixed baseplate.

In the above embodiment, when the surface layer of the soil is soft and the hardness is gradually increased along with the gradual increase of the depth, the extension length of the return spring 6 is gradually increased along with the continuous penetration of the screw rod 5 into the soil, the tension thereof is increased along with the gradual increase of the extension length, and the screw rod 5 is difficult to continue to move downwards when drilling is easy to occur on harder soil. At the moment, the lifting column 10 sleeved on the upright column 9 can rotate, the pressing plate 13 on the lifting column 10 is adjusted to be above the convex plate 8 on the engine base 4, at the moment, the air cylinder 11 works to apply downward pressure to the lifting column 10, and downward pressure is indirectly applied to the engine base 4, so that the drilling work of hard soil is realized. When the soil reaches the drilling depth, the engine 3 stops working, the screw rod 5 stops rotating, the air cylinder 11 slowly retracts, the return spring 6 pulls the engine base 4 to move upwards, and in the process that the air cylinder 11 slowly retracts, the lifting column 10 can be rotated, the pressing plate 13 of the lifting column 10 is moved away from the upper portion of the convex plate 8 of the engine base 4, and the engine base 4 can be reset.

As an optimal technical scheme of the utility model, the clamp plate 13 of lift post 10 side surface can be equipped with the multiunit, and on the side surface of multiunit clamp plate 13 vertical arrangement and lift post 10, applicable in the action of pushing down that the flange 8 on engine base 4 is in under the not co-altitude condition. In addition, the upper end of the convex plate 8 of the engine base 4 can be provided with a stop block, so that when the pressing plate 13 on the lifting column 10 presses the convex block downwards, the pressing plate 13 can limit the position of the upper surface of the convex plate 8, and the danger that the pressing plate 13 slips from the convex block of the engine base 4 due to the rotation of the lifting column 10 and impacts operators is avoided.

As an optimal technical scheme of the utility model, the lower extreme of cylinder 11 piston rod can pass through bearing arrangement with the upper end of lift post 10 and be connected, makes the upper end of lift post 10 be connected with the outer lane of bearing, and the lower extreme and the bearing inner circle of cylinder 11 piston rod are connected, are that lift post 10 can rotate for cylinder 11 piston rod. With the above connection, the structural part of the spring 12 can be eliminated. However, the connecting bearing between the piston rod of the cylinder 11 and the lifting column 10 has short service life and needs to be replaced frequently.

The downward pressing driving device 7 can also adopt a screw rod structure, and the motor screw rod mechanism drives the engine base 4 to lift, so that full-mechanized operation is realized. However, the driving motor 3 must be driven by a lead screw to move up or down, which is a disadvantage in that it consumes power in the whole process. Compare in the utility model discloses a bore native machine provides upward pulling force through reset spring 6 and makes it reset, need not to adopt mechanisms such as motor, can realize resetting by oneself. In addition, at the initial stage of the soil drilling stroke of the screw rod 5, due to the structural design of the screw rod 5, the soil drilling action of the screw rod 5 can be met only by small downward pressure, but the pure mechanical screw rod structure cannot achieve the effect, and only downward pressure can be applied to the screw rod 5 through the rotation of the screw rod.
