본 발명은 핸드드릴과 결합되는 몰탈교반용 교반날개의 강도 보강장치에 관한 것으로, 더욱 바람직하게는 시멘트 몰탈을 교반하는 교반날개가 핸드드릴과 결합하여 교반할 때, 핸드드릴과 연결되는 연결부분의 회전봉이 강력한 회전력에 의하여 절단되는 것을 방지하기 위하여 교반날개의 연결부분의 강도를 보강하여 교반날개 작업시 연결부분의 회전봉이 절단되지 않도록 하기 위한 핸드드릴과 결합되는 몰탈교반용 교반날개의 분리장치에 관한 것이다.The present invention relates to a device for reinforcing the strength of a stirring blade for agitating mortar combined with a hand drill, and more preferably, when the stirring blade for stirring the cement mortar is combined with the hand drill to stir, In order to prevent the rotating rod from being cut by strong rotational force, the strength of the connecting part of the stirring blade is reinforced to prevent the rotating rod of the connecting part from being cut when working with the stirring blade. About.

일반적으로 건설 현장에서 사용되는 몰탈(시멘트,모래)은 일반미장, 뿜칠미장, 조절, 바닥, 조인트, 사춤용으로 널리 사용되고 있으며, 이러한 몰탈은 현장에서 용기에 담아져 삽 등을 이용하여 수작업으로 혼합하고 있기 때문에 충분한 교반이 이루어지지 않을 뿐 아니라 많은 인력이 동원되고, 시간이 많이 소요되므로 작업하기 불편한 단점이 있었다.In general, mortar (cement, sand) used in construction sites is widely used for general plastering, spray plastering, adjustment, floor, joint, and sanding, and these mortars are contained in a container at the site and mixed by hand using a shovel, etc. Because it is not sufficiently agitated, it is inconvenient to work because a lot of manpower is mobilized and a lot of time is required.

따라서 종래에는 상기와 같은 단점을 감안하여 전기를 이용하는 핸드드릴에 교반날개를 장착하여 회전시킴으로써 몰탈을 혼합 및 교반할 수 있는 핸드 드릴용 몰탈 믹서기가 안출된 바 있다.Therefore, conventionally, in consideration of the above-described disadvantages, a mortar mixer for a hand drill capable of mixing and stirring the mortar by rotating by attaching a stirring blade to a hand drill using electricity has been devised.

상기 핸드드릴에 교반날개를 결합하여 사용하는 경우에는 교반날개의 구조상 많은 문제가 있는 것이었다.In the case of using a stirring blade combined with the hand drill, there were many problems in the structure of the stirring blade.

즉, 종래 사용되고 있는 교반날개를 원형 봉상의 회전봉에 일체가 되게 결합한 다음 교반날개를 핸드드릴에 삽입하여 볼트로 체결고정되게 한 것이거나, 원형봉 상에 회전날을 용접한 것이다.That is, the conventionally used stirring blade is integrally coupled to a circular rod-shaped rotating rod, and then the stirring blade is inserted into a hand drill to be fastened and fixed with a bolt, or a rotating blade is welded on a circular rod.

상기한 구성의 교반날개를 핸드드릴에 볼트로 체결한 경우에는 사용중 볼트가 이완되면서 공회전하게 될 뿐 아니라, 교반날개의 회전력에 의한 볼트의 결합부분에 강도가 약하여 회전봉이 볼트결합 부분의 상부측에서 절단되는 문제점이 있었던 것이다.When the stirring blades of the above configuration are bolted to the hand drill, the bolts loosen during use and idle, as well as the strength of the bolt joints due to the rotational force of the stirring blades is weak. There was a problem of being cut off.

이러한 문제점을 도면을 통하여 살펴보면, 도 1에 나타내는 바와 같이, 핸드드릴(100)에 교반날개(200)가 결합된 회전봉(210)을 결합하기 위해서는 핸드드릴(100)의 결합부(110)에 회전봉(210)을 삽입하여 볼트(213)를 체결하여 고장시킨 후 사용하게 되는데, 이 구성은 전술한 바와 같이, 몰탈을 교반하게 되면 핸드드릴(100)에 볼트(213)로 결합된 회전봉(210)이 강한 회전력에 의해 몰탈에 저항을 받아 볼트(213)의 상부측 인 회전봉(210)이 절단하게 되는 문제점이 발생하여 사용하는데 많은 불편이 있었던 것이다.Looking at this problem through the drawings, as shown in FIG. 1, in order to couple the rotating rod 210 to which the stirring blade 200 is coupled to the hand drill 100, the rotating rod is connected to the coupling portion 110 of the hand drill 100. It is used after fixing the bolt 213 by inserting 210, and this configuration is, as described above, when the mortar is stirred, the rotating rod 210 coupled with the bolt 213 to the hand drill 100 Due to this strong rotational force, there was a problem in that the rotation rod 210, which is the upper side of the bolt 213, was cut due to resistance to the mortar, and there was a lot of inconvenience in using it.

즉, 보강볼트(30)의 상부측에서는 교반날개(200)가 회전시 몰탈에 저항을 받아 부하가 걸리게 되어 회전봉(210)이 절단되어 사용에 많은 애로점이 있었다.That is, at the upper side of the reinforcing bolt 30, the stirring blade 200 receives resistance from the mortar when rotating and a load is applied, and the rotating rod 210 is cut, causing many difficulties in use.

그러나 본 발명에서는 핸드드릴(100)에 결합되는 연결부(40)에 다시 회전봉(210)을 연결한 다음, 연결부(40)의 상부측이 절단되지 못하도록 회전봉(210)의 단부측에 보강볼트(30)를 2단으로 결합하여 구성한 것이다.However, in the present invention, after connecting the rotating rod 210 to the connecting portion 40 coupled to the hand drill 100 again, the reinforcing bolt 30 is placed on the end side of the rotating rod 210 so that the upper side of the connecting portion 40 is not cut. ) Is combined in two stages.

상기 연결부(40)에 결합되는 회전봉(210)을 돌출나사산(10)과 보강나사산(20)으로 이루어지게 2단으로 나사산(50)을 형성하여 상기 나사산(50)에 보강볼트(30)를 결합하여 교반날개(200) 회전시 몰탈에 저항을 받아 부하가 걸리는 부분을 보강볼트(30)로 보강함으로써 회전봉(210)이 몰탈 교반시 부하가 걸리지 않게 되므로 절단되는 것을 방지하게 되는 것이다. The reinforcing bolt 30 is coupled to the screw thread 50 by forming a screw thread 50 in two stages so that the rotating rod 210 coupled to the connection part 40 is composed of a protruding screw thread 10 and a reinforcing screw thread 20 Therefore, when the stirring blade 200 is rotated, the portion that is subjected to the load due to resistance to the mortar is reinforced with the reinforcing bolt 30, so that the rotating rod 210 is prevented from being cut because the load is not applied during the mortar stirring.
