In Figure 11 (a) and Figure 11 (b), or in Figure 11 (c) and Figure 11 (d), the position of potential difference meter test pin 88a is different respectively, but the angle of inclination of pin clamping components 92 is identical, so, potential difference meter 93 can not detect both position difference of potential difference meter test pin 88a at Figure 11 (a) and Figure 11 (b), or in both position difference of potential difference meter test pin 88a of Figure 11 (c) and Figure 11 (d).Therefore, the plectane 89 of band projection is set, whether the protruding 89a by this plectane 89 is contacted with switch 87, can detect both difference of position of potential difference meter test pin 88a at Figure 11 (a) and Figure 11 (b), or in both difference of position of potential difference meter test pin 88a of Figure 11 (c) and Figure 11 (d).
Like this, can drive line concentrator marker 53R, the 53L of both sides by single concentrator marker drive unit 82, so, constitute simply, can realize that cost reduces.In addition, the shape of the cam 84 by improvement concentrator marker drive unit 82, thereby can drive concentrator marker 53R, the 53L of both sides respectively, so, the not only function unanimity of concentrator marker 53, and each concentrator marker driving timing staggers, so, identical with the situation that drives each concentrator marker 53 by the load that acts on single electromotor 85, do not need powerful electromotor.
In addition, when lifting concentrator marker 53 by the swing of the L font arm 80 that is connected to cam 84, form to the speed of the concentrator marker 53 that begins to lift as reduction cam 84 shown in Figure 12 ' shape, then can reduce at drag-line, electromotor, cam, and the load of arm.Cam 84 ' shape as shown in Figure 12 the abutment portion of L word shape arm is formed mild curve.
In addition, by cam face being formed, thereby when mobile the stopping of concentrator marker, do not stop suddenly, so the mud that is attached to concentrator marker can not be splashed to the operator when the mobile mild cam face that lifts concentrator marker when finishing near concentrator marker.
In addition, also can concentrator marker drive unit 100 shown in the side view of the plane of Figure 13 (a) and Figure 13 (b) be set for 1 couple of line concentrator marker 53L, 53R about being used at connecting rod support framework 42 shown in Figure 1.
The concentrator marker drive unit 100 of present embodiment is the concentrator marker drive unit of the drag-line 101 that uses marmem system, about drag-line 101,101 be provided with 2 respectively accordingly.Drag-line 101 is made by marmem, is rolled onto the drag-line of being located at 8 word rings 102 in the concentrator marker drive unit 100 and partly its end is connected to the plastic conversion rod 103 of insulating properties that reaches the outside from a sidewall of concentrator marker drive unit 100 as the drag-line of marmem system.The one end resistance of conversion rod 103 is located at the elastic force of the spring 104 in the concentrator marker drive unit 100 and is provided with extendingly, and the other end is connected in the exercisable handle of not shown operator.
In addition, line concentrator marker 53 is swung under the situation in field, when the operator makes conversion rod 103 starts, interlock therewith, electric current flows to drag-line 101, is rolled onto drag-line 101 distortion of the marmem system of 8 word rings 102.As a result, the length of drag-line 101 integral body is elongated, and the concentrator marker 53 of drag-line front end is swung to the field.
In the concentrator marker drive unit 100 of the drag-line 101 that uses such marmem system, compared with the prior art, constitute simply, can realize miniaturization, lightweight, cost degradation.
The present invention can be used for having the working in paddy field of line concentrator marker, and the table soil portion in field drawn the fuselage advance route of next stroke to by this line concentrator marker when returning operation.
