Description

An apparatus for making sowing hole

The present invention relates to a seeding grooving machine for forming seedling grooves at regular intervals in order to sow crops, and more particularly, to a seeding grooving machine in which a rechargeable electric drill required for digging a seedling groove on a hard ground surface is easily detached and attached .

It is called 'sowing' to plant seeds or similar seeds in the fields to raise grain or vegetables. Most of the farmers who do paddy farming do not sow directly on the rice fields, Since the plant is transferred to rice fields, sowing in Korea is mainly performed in field farming.

On the other hand, the time of sowing differs depending on the kind and variety of crops, and is determined by the cultivation area, farming system, soil condition, disaster condition, discharge, effort assessment, etc. In farmhouses mainly farming fields, crops are usually harvested every season, By repeating the sowing process, the farmer's income is raised by making four seasons farming.

However, when crops are harvested after harvesting in the fall, it is often the case that soybean crops are sown and cultivated. In order to sow soybean crops, seeds are usually sown at a depth of 3 to 5 cm.

However, since the ground is frozen firmly in winter, it is very difficult to form seeding grooves having a depth of 3 to 5 cm at a certain interval for sowing, and there is a problem that a lot of labor is required.

In order to solve the above-mentioned problems, the applicant of the present invention has proposed an apparatus and a method for manufacturing a seed injection molding machine in which a motor driven by a direct current battery is installed in a molding machine body and a chuck is attached to a lower end of a motor rotation shaft, A seed injection molding machine (hereinafter referred to as " seed injection molding machine ") which forms seed injection grooves while rotating the seed injection grooves, , 'Sowing groove molding machine') was filed in 2008 as utility model application and registered as utility model registration No. 20-0444342.

However, in the conventional seeding grooving machine, there is a problem that when the electric motor breaks down, the seeding operation using the seeding grooving machine is impossible because the electric motor that operates as a DC battery is installed in the main body of the molding machine.

Further, when the motor can not be repaired, a new sowing groove molding machine must be newly purchased, thereby increasing the cost of purchasing the motor by repeatedly spending it, thereby increasing the economic burden.

The object of the present invention is to provide a rechargeable electric drill which can be easily attached to and detached from a conventional rechargeable electric drill, And it is an object of the present invention to provide a seeding groove molding machine capable of reducing costs and configuring an apparatus to suit user's preference.

The present invention is characterized in that a vertical bar 101 having an engaging portion 101a provided with a through hole 101b at its upper end and a transverse bar 102 having a hollow portion 102a formed therein are connected at right angles to each other, A main body (1) integrally formed with the connection interposer (103), a case having a bearing integrated therein at one end of the vertical bar (101);
