Benefits of technology

[0009] It is therefore the object of the present invention to provide an improved apparatus for drilling a hole, preferably in a golf green, which has lower manufacturing costs, which has a lower weight and which is very easy to operate during the drilling process and which has a simple and easily operated ejection arrangement for the ejection of a drilled-out earth plug into an existing hole.

Problems solved by technology

Prototype and field tests have shown some drawbacks of this apparatus.
For example, the ejection system of the apparatus is complicated and not simple enough to operate, the weight of the apparatus is too high, and the manufacturing costs of the apparatus are too high.

Embodiment Construction

[0101]FIG. 1 shows a new and improved apparatus 1 according the present invention and which comprises a handle 2 with a centrally arranged battery element 13, control means 3 with retainer plates 5,6,7, a tread plate 8 with an opening 9, a protecting means 10, angle adjustment means 11, and a cutter head 12.

[0102] The retainer plates 6,7 are adapted to slide along the control means 3 during the drilling process.

[0103] The handle 2 is connected with a shaft 2′ constituting a housing for a drive motor 21 and connecting the handle with a central retainer plate 6. Between the central retainer plate 6 and the lowermost retainer plate 7, a connecting rod arrangement 20 and a gearing arrangement 22 (see FIG. 4) is disposed. The gearing arrangement 22 and the connecting rod arrangement 20 connect the drive motor 21 (see Fig.4) housed in the shaft 2′ with the cutter head 12 and provide for transforming the rotation of the drive motor 21 into a reciprocating turning movement of the cutter h...
