Description

Drill for drilling fungus-planting hole for cultivating mushroom

The present invention relates to a drill drill for forming a hole for planting seedlings in the mushroom cultivation tree, and in particular, it is possible to combine the handle of various angles by the fastener coupled to the head side of the drill tool, as well as to the fixture The reinforcement posts can be used to control the depth of phagocytosis and to prevent the scattering of wood chips. It is a tool.

In order to grow mushrooms, a hole of a certain depth is formed in a mushroom cultivation tree cut to a certain length using a drilling machine equipped with a drill blade, and then the mushroom spawn is inoculated into the hole, and then the styrofoam is formed at the entrance of the planted hole. Or by inserting a stopper, such as cotton, mushroom spawn growing inside the hole grows out of the stopper is artificially producing a large number of mushrooms.

Here, in order to form the hole for mushroom phagocytosis, a special drill blade is used instead of a general drill blade. The general shape of the drill blade has a body having a groove on a spiral groove on one side of the fixed shaft, and an end of the body. Consists of the formed threaded portion, which allows the selection and securing of the exact position to be formed by the screwed portion described above, and forms a primary small hole by the threaded portion, and then, The hole is formed to match the body diameter of the drill blade.

In addition, the drill tool to which the drill blade is fixed is a rotary tool coupled to one side of the body in which the electric motor is built, such as Utility Model Registration No. 36805 in 2000 and Utility Model Registration Application No. 2268 in 2003. Using a drill drill having a drill chuck coupled to the sphere, by using a separate chip shatterproof cover on the rotation side of the drill drill, or by using a combination of the drilling depth control, the wood chip when drilling the phagocytosis It has been proposed to prevent scattering and to form a constant depth of drilling.

However, the chip shatterproof cover used in the drilling drill as described above, when the depth of the phagocytosis is to be set differently, it is not possible to adjust the coupling position, which is rather a problem of working, and vibration generated during the drilling work. Has a structure that is vulnerable to shocks,

The control mechanism is also nut is coupled to the screw rod coupled to the fixture, there is no shatterproof function of the wood chip, as well as if the screw rod is bent or bending the control mechanism, the interference occurs with the drill blade to work Because of the nature of the drill tool, the drill tool must be pressed and drilled to the wood side, so that the coupling part of the screw rod is sheared by these working conditions.

In addition, the prevention of chip scattering during the drilling operation and phagocytic holes of a certain depth act as a factor for improving the drilling workability and increasing the mushroom cultivation. Each drill drill as described above has only one function. Therefore, there is a problem that does not satisfy both of the above conditions.

In particular, the drill chuck of the conventional drill drill as described above is inserted into the inner end of the rotary hole, the pressing piece having a tapered inclined surface is divided and the drill piece is inserted while the pressing piece is collected inward by the combination of a separate tightening nut It is a structure that allows the blade to be fixed, and the above-mentioned pressing pieces have good bending strength and use a soft material or copper of a somewhat soft material. The pressing pieces of these materials are used to firmly mount the drill blades and then the drills. When the blade needs to be replaced, the pressing piece of a material having a relatively low elastic force is pressed into the inner end of the rotary hole, so that it is not easily separated.

The present invention is devised to eliminate the problems as described above, coupled to the rotating side of the drill tool is coupled to the reinforcement posts coupled to both sides, the drill chuck is rotatably coupled to the end of the rotating tool that is rotated inside the fixture By screwing the tightening nut, and by coupling the taper-shaped control port having an opening downward and a coupling hole on both sides to the threaded portion of the reinforcement post,

The reinforcement posts enable the firm and stable coupling of the control mechanism, as well as control the coupling position while preventing the scattering of wood chips by the control mechanism, so that the puncture depth of the phagocytosis can be arbitrarily controlled and tightened. It is an object of the present invention to provide a drill tool for forming a mushroom hole for mushroom cultivation, since the drill chuck is separated together when the nut is separated.
