The ground cultivated by (5) is selected evenly by the blade (21).

운전자가 탑승시 운전석(27) 하부에는 뒷바퀴(35)가 지지하고 있으므로 경운작업에 지장이 없으며, 운전자는 발판(38)에 발을 딛고 안정되게 운전할수 있는 것이다.Since the rear wheel 35 is supported under the driver's seat 27 when the driver boards, there is no problem in tilling, and the driver can stably drive the foot on the footrest 38.

작업에 있어서 경작지면의 상태에 따라 삽날(21)의 높이를 조절하거나 삽날(21)전면의 흙을 털어서 펴는 경우에는 연결간(15)에 설치된 조작레버(16)을 운전자쪽으로 당겨서 삽날(21)을 상향회동시키거나, 괘지핀(17)을 핀공(19)에서 뺀다음 체인(25)을 끌어올려서 삽날(21)의 높이가 적정높이로 되는 위치에서 체인(25)을 괘지핀(17)으로 괘지하면 된다.In operation, in order to adjust the height of the blade 21 according to the state of the tilled ground or to shake off the soil on the front of the blade 21, pull the operation lever 16 installed in the connecting rod 15 toward the driver blade (21). Rotate upward, or pull the chain pin (17) from the pin hole (19) and then pull up the chain (25) to the chain pin 25 at the position where the height of the blade (21) to the appropriate height You can just hang it.

즉, 조작레버(16)를 운전자측으로 당기면 연결간(15)에 의해 연결된 양측 회동간(14)이 제3(a)도와 같이 힌지축(12)을 중심으로 하여 일체로 상향회동하면서 연결간(15)의 양측단에 있어서 괘지핀(17)으로 괘지된 체인(25)을 끌어 올리게 되고 이에 따라 하단양측의 체인고리(24)에 체인(25) 하단이 연결된 삽날(21)이 지지간(22)에 대하여 힌지핀(46)을 중심으로 상향 회동되며, 다시 조작레버(16)를 놓으면 삽날(21)의 자중에 의해 삽날(21)과 회동간(14), 연결간(15)이 제3(a)도 상태로 회동복귀되는 것이다.That is, when the operation lever 16 is pulled toward the driver's side, both side pivots 14 connected by the connecting rods 15 pivot upwardly integrally about the hinge shaft 12 as shown in FIG. 15, both ends of the chain (25) hooked up with the hanging pin 17 is pulled up, so that the lower blade chain 21 is connected to the chain ring 24 on both sides of the lower blade (21) support rod 22 Rotation about the hinge pin (46) with respect to the center, and when the operation lever 16 is released again, the blade 21 and the pivot 14, the connecting portion 15 by the weight of the blade 21 is connected to the third (a) is also returned to the state.

이러한 조작을 반복하는 것에 의해 삽날(21) 전방의 흙을 털어내거나 분산시킬 수 있다.By repeating such an operation, the soil in front of the blade 21 can be shaken off or dispersed.

삽날(21)의 높이를 조절하여 고정함에 있어서는 괘지핀(17)에 의한 체인(25)의 괘지위치를 변경하여 연결간(15)와 삽날(21) 하단 사이에서의 체인(25)의 길이를 조정함으로써 삽날(21)의 높이를 소저높이로 고정할 수 있는 것이다.In adjusting and fixing the height of the blade 21, the length of the chain 25 between the connecting rod 15 and the lower edge of the blade 21 is changed by changing the locking position of the chain 25 by the locking pin 17. By adjusting, the height of the blade 21 can be fixed to the height of height.

삽날(21)에 의한 지면의 평탄작업이 필요치 않은 경우에는 조작레버(16)에 의해 삽날(21)을 들어 올리거나 괘지핀(17)에 의한 체인(25)의 길이를 줄여서 삽날(21)을 들어 올리면 된다.When the grounding operation of the ground by the blade 21 is not necessary, the blade 21 is lifted by lifting the blade 21 by the operating lever 16 or by reducing the length of the chain 25 by the locking pin 17. Just lift it up.

조작레버(16)에 의해 삽날(21)을 들어 올림에 있어서는 고정프레임(11)과 연결간(15) 사이에 연결된 인장스프링(20)의 탄성력에 의해 작은 힘으로도 조작할 수 있게 된다.In lifting the blade 21 by the operation lever 16, it is possible to operate with a small force by the elastic force of the tension spring 20 connected between the fixed frame 11 and the connecting rod 15.

로타리 경운날(5)에 의한 경운깊이를 조절함에 있어서는, 지지간(26) 중간부에 설치된 조절나사봉(33)을 회전시키면 지지관(32)내에서 나사 결합된 뒷바퀴포크(36)의 나사관(37)이 승강되면서 뒷바퀴(35)가 승강되어 상대적으로 로타리 경운날(5)의 경우 깊이가 깊고 얕게 되는 것이다.In adjusting the tilling depth by the rotary tilling blade 5, when the adjusting screw rod 33 installed in the middle of the supporting section 26 is rotated, the screw of the rear wheel fork 36 screwed in the supporting tube 32 is rotated. As the officer 37 is lifted, the rear wheel 35 is lifted, so that in the case of the rotary tiller 5, the depth is deep and shallow.

한편 경작지가 연약지반으로써 운전자가 탑승하면 뒷바퀴가 깊게 빠질 염려가 있거나 기타 탑승하지 않을 경우에는 운전석(27)을 지지간(26)에 고정된 축(28)을 중심으로 하여 전방으로 회동 절첩한 다음 경운기(1)의 조향 핸들을 잡고 보행 작업을 행하면 된다.On the other hand, when the driver's aboard ground is soft ground, the rear wheel may fall deeply or when the driver does not ride, the driver's seat (27) is pivoted forward about the shaft (28) fixed to the support section (26). What is necessary is just to hold the steering wheel of the tiller 1, and to walk.

이상과 같이 본 고안에 의하면 작업자가 탑승한 상태에서 편리하고 능률적으로 작업할 수 있으며, 승강 회동 가능하게 설치된 삽날에 의해 경작지의 평탄작업을 행할 수 있고, 필요에 따라서는 운전석을 전방으로 절첩하고 경운기의 조행 핸들을 잡은 상태에서 보행작업으로 전환할 수도 있는 등 매우 편리하고 유용한 것이다.As described above, according to the present invention, the operator can work conveniently and efficiently in the state of boarding, and the flat work of the arable land can be performed by the blade installed so that the elevating rotation is possible, and if necessary, the driver's seat is folded forward and the tiller is It is very convenient and useful, such as switching to walking while holding the steering wheel of.

또한 본 고안은 기존 로타리 작업기에 조립식으로 설치한 것이므로 종가에서 기존 사용중인 모든 로타리 작업기에 설치 사용할 수 있어 더욱 편리한 것이다.In addition, since the present invention is prefabricated to the existing rotary work machine, it is more convenient to install and use on all existing rotary work tools in the closing price.
