下端部に滑動片１６が突設されている。 In addition, an auxiliary excavation body 7 is provided at the lower end of the left and right beams 2.
is inclined forward and downward and protrudes so as to be reversible in the left and right direction. These left and right auxiliary digging bodies 7 have a triangular shape in plan view, and are narrow in width so as to follow the grooves between the furrows in the field. A reversing spatula 9 is connected to the rear end of the raising body 7. The left and right auxiliary digging bodies 7 are fixed to the front end of a rotating horizontal shaft 11 rotatably provided at the lower end of the beam 2 via a guide groove frame 10.
The lower end of a handle bar 13 is integrally fixed to the rear end via a connector 12, and the upper part of the handle bar 13 is attached to a plurality of stopper bodies 14 fixed to the upper part of the vertical part 4 of the beam 2. It is designed to be selectively locked in the locking recess 15. and,
By changing the position of the handle rod 13 with respect to the plurality of locking recesses 15, the auxiliary digging body 7 can be turned over in the left-right direction via the horizontal rotating shaft 11. Further, a sliding piece 16 is provided protruding from the lower end of the guide horizontal frame 10 of the horizontal rotating shaft 11.
さらに前記フレーム１の中間部にロワーピン１
７およびトツプマスト１８が突設されている。 Furthermore, a lower pin 1 is attached to the middle part of the frame 1.
7 and a top mast 18 are provided in a protruding manner.

が安定かつ円滑に行なわれる。 In such a configuration, the excavator is connected to the towing vehicle via the lower pin 17 and the top mast 18. When the excavator is towed along the ridge in the field by a tractor, the main excavator body 5
The crops in the ridge are dug up, and the crops are dug up to the rear upper part via the main excavation body 5. At this time, the main excavation body 5 is supported by the auxiliary excavation bodies 7 on its left and right sides, so stable excavation work is performed, but straw and weeds can be found in the trench through which the auxiliary excavation bodies pass. If there is a problem, they are removed or dug up by the auxiliary excavation body 7 and reversed in the selected direction, either left or right in the direction of travel.
Therefore, due to the action of this auxiliary digging body 7,
The main excavating body 5 is not swung, and the digging operation by the main excavating body 5 is performed stably and smoothly as a whole due to the biting ability of its tip 8.

作業が一層円滑に行なわれる。 Next, in the structure shown in FIG. 2, the front ends of horizontal parts 3 of beams 2 serving as left and right frames are pivoted to both ends of a frame 1 by a connecting horizontal shaft 20 so as to be rotatable in the vertical direction. It is something. In this case, a transmission 22 having an input shaft 21 for inputting power from the towing vehicle is fixed to the middle part of the frame 1.
Output shaft 23 protruding rearward of this transmission 22
A cam 24 is pivotally attached to the cam 24, and a driven roller 25 is engaged with the cam 24. and a coil spring 2 between the lower end of the top mast 18 of the frame 1.
7 is tensioned, and this coil spring 27 biases the driven roller 25 so that it always engages with the cam 24. As a result, when the input shaft 21 of the transmission 22 is connected to the power output shaft of the towing vehicle and the transmission 22 is driven in conjunction, the cam 24 is rotated and The left and right beams 2 are swung vertically about the connecting horizontal shaft 20, and therefore the left and right main excavation bodies 5 and auxiliary excavation bodies 7 are synchronously swung vertically and advanced. As a result, the excavation work can be carried out even more smoothly while maintaining its biting ability and stability.

According to the present invention, since the auxiliary excavation bodies are provided at both the left and right ends of the main excavation body, the entire body can be reliably shortened in the longitudinal direction, and the direction can be easily changed on small headlands during reciprocating work. In addition, weeds in the ridges and grooves can be reliably disposed of by the auxiliary excavation body, so that the main excavation body can dig in and out without being affected by the condition of the ridges. The stability of the work can be ensured without damaging the harvest, and the left and right auxiliary digging bodies can stably support the main digging body and treat weeds in the ridges and grooves, making it possible to use a ruler wheel separately. Since no special parts are required, the number of parts can be reduced and costs can be reduced.Moreover, the left and right auxiliary excavation bodies can be reversed left and right, so depending on the condition of the ridge and groove, weeds can be removed from the ridge side or opposite to the ridge side. It can be excluded in either direction.
