농업용 굴착 스크류 {Excavating screw for agriculture}Excavating screw for agriculture

본 발명은 농업용 굴착 스크류에 관한 것으로, 더욱 구체적으로는 원예작물의 보목이나 비닐하우스 지주의 설치 또는 칡뿌리를 절단 등을 하기 위해 지면에 일정깊이의 구멍을 굴착할 수 있도록 하는 스크류본체에 굴착물을 상향이송하여 배출하는 이송스크류의 하부에 흙과 함께 돌맹이 등과 같은 단단한 물체가 있는 지반을 용이하게 굴착함과 이를 이송스크류에 안정적으로 퍼올릴 수 있도록 한 굴착날이 구비되어 있는 농업용 굴착 스크류에 관한 것이다.The present invention relates to an excavation screw for farming, and more specifically to an excavation in a screw body that can excavate a hole of a certain depth in the ground for the care of gardening crops or the installation of a vinyl house prop or cutting the roots. Regarding the excavation screw for agriculture, which has easy excavation of the ground with a solid object such as boulder together with soil at the lower part of the conveying screw discharged by upward conveying, and an excavation blade for stably spreading it on the conveying screw. will be.

일반적으로 농업용 굴착 스크류는 원예작물의 보목이나 비닐하우스 지주를 설치하기 위한 구멍을 형성하거나 농작물에 피해를 입히는 칡뿌리 등을 절단하기 위해 일정깊이로 지반을 파내어 구멍을 굴착하기 위해 사용된다.Generally, agricultural excavation screws are used to excavate holes to a certain depth to form holes for planting horticultural crops or to support a plastic house, or to cut roots that damage crops.

이러한 종래의 농업용 굴착 스크류는 일정길이로 된 봉체의 외주면 하부 첨단에서 부터 상측으로 스크류날개가 나선형으로 선회되어 이루어진 이송스크류로 구비되어 있는 형태로 되어 있는바, 이는 상측에서 지반을 향해 스크류날개가 회전 및 하향진입하면서 흙을 절삭함과 아울러 절삭된 흙을 상층부로 이송하여 배출하는 형태로 구멍을 형성한다.The conventional agricultural drilling screw has a form in which a screw is spirally rotated upward from the lower edge of the outer circumferential surface of the rod body having a predetermined length, and the screw blade rotates from the upper side to the ground. And while cutting down the soil while entering downwards to form a hole in the form to discharge the discharged soil to the upper layer.

이러한 굴착 스크류에서는 이송스크류에 의해 흙을 절삭하는 과정에서 돌맹이와 같은 단단한 물체가 있는 경우에는 이송스크류의 스크류날개에 돌맹이가 부딪히면서 쉽게 손상될 우려가 있을뿐만 아니라 횡방향으로 배치되는 나선형의 스크류날개 부분이 지반에 수평으로 접촉되기 때문에 지반이 무른 상태이거나 돌맹이와 같은 장애물에 부딪히게 되는 경우에 스크류가 더이상 하향 진입이 되지 못하고 공회전되는 등 문제점이 있었다.In such a drilling screw, if there is a hard object such as boulder in the process of cutting the soil by the feed screw, the screw blade of the feed screw may easily be damaged by hitting the screw wing of the feed screw as well as the helical screw blades arranged in the lateral direction. Since the ground is in contact with the ground horizontally, if the ground is soft or hit an obstacle such as boulder, there was a problem such that the screw can no longer go down and idling.

본 발명은 이러한 문제점을 해결하기 위한 농업용 굴착 스크류에 관한 것으로서, 스크류본체에 이송스크류와 굴착날을 각각 형성하여 이송스크류에서는 봉상을 따라 나선형으로 선회되는 형태로 구비된 스크류날개에 의해 굴착물의 상향이송 및 배출이 원활하게 이루어지게 하되 상기 이송스크류의 하부에는 지반을 쉽게 파들어 갈 수 있도록 함과 아울러 돌맹이 등과 같은 단단한 물체를 굴착할 수 있으면서 이송스크류에 원활하게 퍼올려질 수 있도록 한 작업효율성과 내구성을 크게 향상시킬 수 있도록 한 농업용 굴착 스크류를 제공함에 있다.The present invention relates to an agricultural excavation screw for solving this problem, the feed screw and the excavation blade is formed on the screw body, respectively, in the conveying screw in the screw screw provided in the form spirally spirally along the rod up the transport of the excavation And the discharge is made smoothly, but the lower part of the conveying screw allows the soil to be easily dug and the solid material such as boulder can be excavated while being smoothly spread on the conveying screw. To provide an agricultural drilling screw that can greatly improve the.

Of course, it can be attached and used.

이와 같이 된 본 발명의 농업용 굴착 스크류 구성에 따른 실시예를 상세히 설명하면 다음과 같다.Referring to the embodiment according to the agricultural drilling screw configuration of the present invention as described above in detail as follows.

본 발명은 스크류본체(A)의 상단에 구비된 장착부(120)를 회전동력전달장치에 장착한 다음 스크류본체(A)를 수직으로 위치시켜 굴착하게 되는 것으로, 회전하는 스크류본체(A)의 최하단 첨단절삭부(220)에 구비된 1차절삭면(224)에 의해 굴착하고자 하는 중심지반을 벗어나지 않으면서 정확하고 안정적으로 파들어가는 형태로 굴착작업이 진행된다.The present invention is to mount the mounting portion 120 provided on the upper end of the screw body (A) to the rotary power transmission device and then excavated by positioning the screw body (A) vertically, the lowest end of the rotating screw body (A) Excavation work is carried out in the form of precise and stable digging without leaving the center ground to be excavated by the primary cutting surface 224 provided in the cutting edge portion 220.

즉, 침상형의 경사각을 이루고 판상으로 된 1차절삭면(224)이 구비되어 중심지반을 향해 정확하게 절삭을 하면서 파들어갈 수 있도록 하며, 상기 1차절삭면(224)은 초경합금으로 구비하여 파손 및 마모 등을 방지할 수 있도록 한 구성으로 강력한 굴착력을 갖도록 한다.In other words, the inclined angle of the needle-like plate is provided with a plate-shaped primary cutting surface 224 to be precisely cut while cutting toward the center ground, the primary cutting surface 224 is provided with cemented carbide to break and It has a strong digging force in one configuration to prevent wear.

이렇게 첨단절삭부(220)에 굴착된 중심지반의 둘레는 첨단절삭부(220)의 상측에 위치한 측부절삭부(230)에 의해 절삭된 중심지반 둘레의 측부를 확장 절삭이 됨과 아울러 회전절삭부(240)에 의해 상기 측부절삭부(230)에 절삭되지 않는 외측부분의 지반을 동시에 회전절삭 하고 상기 굴착과정에서 발생된 굴착물은 측부절삭부(230)의 상향경사면(232)을 따라 이송스크류(100)로 퍼올려져서 이송스크류(100)에 의해 이송 및 배출이 된다.Thus, the periphery of the center ground excavated by the cutting edge portion 220 is expanded by cutting the side of the periphery of the center ground cut by the side cutting portion 230 located on the upper side of the cutting edge portion 220 and the rotary cutting portion ( 240 by simultaneously cutting the ground of the outer portion that is not cut to the side cutting portion 230 and the excavation generated in the excavation process along the upwardly inclined surface 232 of the side cutting portion (230) transfer screw ( It is spun up by 100) and is transported and discharged by the transfer screw 100.

즉, 상기 측부절삭부(230)에서는 지지대(210) 둘레에 상향경사면(232)을 이루고 소정 두께로 된 2차절삭면(234)에 의해 중심지반 둘레의 측부를 확장 절삭을 하게 되고 상향경사면(232)을 따라 굴착작업에 의해 발생된 굴착물을 상측의 이송스크류(100)로 퍼올려지도록 한다.That is, the side cutting portion 230 forms an upwardly inclined surface 232 around the support 210, and the side portion around the central ground is expanded by the secondary cutting surface 234 having a predetermined thickness, and the upwardly inclined surface ( The excavated by the excavation work along the 232) is to be raised to the upper transfer screw (100).

상기 측부절삭부(230)의 절삭작업과 동시에 회전절삭부(240)는 측부절삭부(230)에 절삭되지 않는 외측부분의 지반을 회전절삭을 함과 아울러 이송스크류(100)의 스크류날개(110)가 회전하는 회전반경보다 크게 하여 절삭이 이루어지게 되므로 이송스크류(100)는 절삭저항을 받지않으면서 이송 및 배출기능을 원활히 수행할 수 있게 된다.Simultaneously with the cutting operation of the side cutting unit 230, the rotary cutting unit 240 rotates the ground of the outer portion that is not cut by the side cutting unit 230, as well as the screw blades 110 of the transfer screw 100. Since the cutting is made larger than the rotating radius of rotation), the feed screw 100 can smoothly perform the transfer and discharge function without receiving cutting resistance.

상기와 같이 스크류본체(A)의 하부에 위치한 굴착날(200)의 첨단절삭부(220)와 측부절삭부(230)와 회전절삭부(240)에 의해 지반의 절삭지점을 정확하게 절삭할 수 있으면서 절삭저항을 최소화하면서 굴착이 원활히 이루어지고 굴착된 굴착물은 이송스크류(100)에 의해 효과적으로 상향배출하는 수단으로 굴착이 이루어지게 된다.As described above, while cutting edges of the ground can be precisely cut by the cutting edge portion 220, the side cutting portion 230 and the rotary cutting portion 240 of the drilling blade 200 located below the screw body (A). Excavation is performed smoothly while minimizing cutting resistance, and the excavated excavated material is excavated by means of effectively upwardly discharging by the transfer screw 100.
