The left and right disc cutters 49, 49 are arranged at the rear ends of both transmission cases 15, 15, and the front portion of the overlapped portion of both disc cutters 49, 49, that is, the cutting action position, is arranged on both transmission cases. 15 is located at the rear part of the inverted C-shaped space between 15 and 15, and with respect to the second conveying means 9, it is positioned so as to correspond to the end portion of the nipping and conveying path formed by the both nipping belts 38 and 38. ing.

  Below the left and right transmission cases 15, 15, a substantially horizontal lateral cover member 100 for covering the casing 43 and the power distribution shaft 44 is provided so as to be gently rearwardly raised. A pair of left and right cover members 101, 101 are provided to cover each transmission case 15 portion facing the passage space TK, and these cover members 101, 101 are fixed to the upper surface of the cover member 100 so as to stand upright in the front-rear direction. It is formed in a funnel shape in plan view so that the mutual dimension gradually increases as the part is moved forward.

  The front guide plate 66 located on the front side of the discharge conveyor 61 is formed by bending the rear portion of the cover member 100 downward vertically and is positioned adjacent to the front side of the conveyor belt 64. A rear guide plate 67 located on the rear side of 61 is erected adjacent to the rear side of the conveyor belt 64.

  The processing conditions around the disk cutters 49 and 49 and the discharge conveyor 61 will be described. The leaf stem t1 of the onion sent to the cutting action position of the disk cutters 49 and 49 by the second conveying device 9 and the stem pulling belt mechanism 7. Even if this is somewhat bulky, it is guided by the front-side portions of the left and right cover members 101, 101 in a plan view and moves smoothly between the rear portions of the cover members 101, 101.

  Then, the remaining foliage t1 cut by the disc cutters 49 and 49 tends to jump backward due to the rotational force of the disc cutters 49 and 49 immediately before being separated from the spherical portion t3. After being moved, it is smoothly moved rearward while falling by the gravitational action between the left and right vertical rotation central shafts 48, 48 and between the left and right cover members 101, 101. Then, it collides with the rear guide plate 67 and falls smoothly onto the conveyor belt 64. Next, the conveyor belt 64 conveys it to the side of the machine body, and during this conveyance, the front guide plate 66 and the rear guide plate are conveyed. The board 67 prevents the conveyor belt 64 from dropping out to the front and rear sides, and finally the sheet 67 is accurately discharged from the specific position of the machine body to the field.

  On the other hand, the beard root t2 cut by the disc blades 56 and 56 tends to be spun backwards due to the rotational force of the disc blades 56 and 56 immediately before being separated from the spherical portion t3, and thus has been bounced off. After that, many of them fall on the conveyor belt 64 through the locations of the transmission cases 15 and 15, and others fall on the upper surface of the cover member 100 in a substantially horizontal horizontal direction or directly fall on the field. It becomes.

  Further, on the upper surface of the cover member 100, not only the beard root t2 but also the shredded pieces of the foliage portion t1 and earth and sand adhering to the onion fall, and these fallen objects are inclined so that the cover member 100 is inclined downward. Therefore, it is guided and moved forward by the body vibration and dropped so as not to hit the rotating part such as the power distribution shaft 44.

  The processing conditions around the disk cutters 49 and 49 and the discharge conveyor 61 are as described above. Thus, the ball of the onion in which the mustard root t2 is cut by the second cutting device F and the remaining leaf t1 is cut by the third cutting device G. The portion t3 is unpinched at the terminal portion of the second conveying means 9, but a receiving rod 69 that is inclined in a rear low posture at a predetermined angle is provided at the lower direction of the portion, The rear end is positioned corresponding to the receiving port 70a formed in the front wall of the receiving portion 70A of the discharge shooter 70 that is disposed adjacent to the rear direction, and the rear end of the second conveying device 9 is unpinched. The bulbous portion t3 of the onion and the cut mustache root t2 carried along with it fall down to the front portion of the receiving rod 69, move along the receiving rod 69 that is inclined to the rear and move from the receiving port 70a. Dropped into the discharge shooter 70, the receiving port 70a Left and right discharge trough portion 70L shown in FIG. 11 from below position, and is sent to the outside from the outlet 70b of the outer end is guided to one of the 70R.

As shown in FIGS. 10 to 15, the discharge shooter 70 is formed by branching discharge saddle portions 70 </ b> L and 70 </ b> R to the left and right from the lower end portion of the receiving portion 70 </ b> A located at the central portion in the left-right direction. A mechanism for selectively switching the discharge path (discharge path selection mechanism) is formed in the receiving portion 70A on the upper surface side of the lower bottom wall 70b of the branching portions 70L and 70R. An exhaust path switching plate 76 pivotally supported so as to swing left and right around the moving fulcrum shaft 75 is provided.
Then, in order to smoothly move the spherical portion t3 from the receiving rod 69 to the discharge path switching plate 76, a bending guide formed of a synthetic resin material or a rubber material which can be bent from the rear end of the receiving rod 69. The plate 69 a is extended so as to extend inward of the receiving portion 70 </ b> A through the receiving port 70 a, and the rear end of the bending guide plate 69 a is placed on the upper surface of the discharge path switching plate 7.
The receiving portion 70A has a box shape, and includes a front wall and a rear wall, and left and right side walls a1 and a1 and an upper wall a2. As shown in FIGS. 13 and 15, the left and right side walls a1 are provided only at the upper part of the side surface of the receiving portion 70A, and the side portions of the receiving portion 70A excluding the existence range of the side wall a1 are opened. Has been made. A U-shaped notch a3 is formed at the lower edge portion of the side wall a1 so that the fingers can be easily inserted into the receiving portion 70A from the outside.

  The discharge path switching plate 76 is manually operated from the outside of the discharge shooter 70 directly through the opening portion, thereby closing the left discharge hook portion 70L and allowing the right discharge hook portion 70R to communicate with the receiving portion 70A. (Dotted line illustrated position p10 in FIG. 11) and a right-side down position (imaginary line illustrated position p20 in FIG. 11) that closes the right discharge hook 70R and allows the left discharge hook 70L to communicate with the receiving section 70A. Can be switched and maintained.

  For example, as shown in FIG. 11, the spherical portion t3 delivered to the outside of the machine from the delivery outlets 70b of the left and right delivery baskets 70L and 70R of the delivery shooter 70 is supported by a container support part 84 installed on the side of the machine body. The container is accommodated in an open top container CT.

  The receiving portion 70A of the discharge shooter 70 is provided with a clogging detecting means 80 for detecting that the onion spherical portion t3 is clogged here. The detection means 80 includes a detection member 81 that is pushed and displaced by the spherical portion t3 of the onion packed in the discharge shooter 70, and a detection switch 82 that is turned on and operated in association with the push displacement of the detection member 81. ing.

The detection member 81 is a rectangular plate and is positioned on the inner upper part of the box-shaped receiving part 70A, and can swing up and down via a left and right fulcrum shaft 83 supported by the side wall a1 of the receiving part 70A. On the other hand, the detection switch 82 is a commercially available switch, and is fixed to the upper surface wall a2 of the receiving portion 70A in a vertical direction so that the vertical position can be adjusted. Is located. The detection switch 82 is changed from the cut-off state to the on-state when the input portion 82a is pushed upward, and the push displacement state (upward displacement state) of the input portion 82a is maintained in association with the change. The self-holding state is released by mechanically self-holding the input state and rotating the input portion 82a about the vertical axis in a state where no pushing displacement force is applied to the input portion 82a. 82a is displaced downward to return to the original position in the cut state, and when the engine is in the engaged state, the spark plug of the spark plug of the engine 1 is not generated and the engine 1 is not operated. It is built into the engine electrical system.
In order to release the self-holding state of the detection switch 82, a finger is inserted from the cutout portion a3 on the side surface of the receiving portion 70A and the input portion 82a is rotated. At this time, the cutout portion a3 Makes it easy for the operator to operate.

Next, a usage example of the preparation machine according to the present embodiment and the operation of each part will be described.
The aircraft is moved to one end of the kite and ready to move forward toward the other end of the kite. Here, power transmission from the engine 1 to the traveling device A is temporarily interrupted to temporarily stop the running of the aircraft. Thus, the engine 1 is powered only to the adjusting device C.

  Under this state, the worker picks up each of the onions on the basket and sequentially inserts them into the crop support slip supply means C4. In this insertion, the ball portion t3 of the onion is held by hand, and is turned upside down first, and then the neck portion is moved forward to the position b1 between the left and right narrow inclined sliding surface portions sm1 and sm1 forming the lower surface of the crop support sliding supply means C4. The onion thus inserted is supported by the left and right narrow inclined sliding surface portions sm1 and sm1 on the spherical portion t3 in the vicinity of the neck portion, and maintains the inverted posture by the gravity action. The narrow inclined sliding surface portions sm1 and sm1 are quickly slid forward and downward.

  Among the onions thus inserted, the one located at the lowest position between the left and right narrow inclined sliding surface portions sm1, sm1 reaches the crop conveyance start point p1 without requiring power or human power due to gravity action. The onion that has reached here is transported to the preparation device C through the transport path of the front overhanging portion C3 by the transport means such as the spherical portion support transport mechanism 6, and the preparation process is performed as described here. The

  After picking up all the onions present on the fence near the front side of the machine and supplying them to the crop support slip supply means C4, the clutch 2a (not shown) provided in the middle of the traveling transmission system provided on the side of the machine is turned on and off. The clutch lever R to be temporarily operated is operated to advance the aircraft by an appropriate distance and stop again. Here, similarly to the previous case, the onion existing in the vicinity of the front side of the aircraft is picked up, and the narrow inclined sliding surface portion sm1, The signal is supplied to the location b1 during sm1, and thereafter the same processing is repeated.

  The spherical portion t3 after the beard root t2 and the foliage portion t1 are cut and removed by the preparation device C is guided by the receiving rod 69 and falls toward the inner rear side of the receiving portion 70A through the receiving port 70a. At this time, a portion of the mustache root t2 cut by the second cutting device F, earth and sand adhering to the spherical portion t3, and the skin of the spherical portion t3, etc. enter the receiving portion 70A together with the spherical portion t3. Unavoidable. Then, the spherical portion t3 that has fallen backward into the receiving portion 70A is given an external force toward the switching side of the discharge switching plate 76, that is, leftward in the illustrated example, and is guided obliquely to the left rear and downward. The spherical portion t3 guided in this manner descends on the bottom surface g of the discharge rod portion 70R, and eventually comes out from the delivery port 70b and falls into the container CT.

  During such a preparation process, the spherical portion t3 moved into the discharge shooter 70 is caused by the presence of, for example, the roots t2, earth and sand accumulated in the discharge shooter 70, and the skin of the spherical portion t3. Since it does not fall smoothly on 70R, it may clog in the discharge chute 70. If this is left unattended, the onions one after another sent from the processing unit C2 accumulate in the processing unit C2 and the discharge shooter 70. If it becomes like this, it will be necessary to take out the staying onion out of an apparatus, and it will take much time and an onion will be damaged.

  However, in this embodiment, when the spherical portion t3 is clogged in the discharge shooter 70 and the number of the spherical portions t3 staying in the discharge shooter 70 increases, the processing force from the processing unit C2 to the second transfer device 9 and the like is increased. The spherical portion t <b> 3 pushed into the receiving portion 70 </ b> A pushes the detection member 81 higher than the specific height position around the left-right fulcrum shaft 83. The detection member 81 pushed up in this way pushes and displaces the input portion 82a of the detection switch 82, thereby displacing the detection switch 82 from the cut-off state to the on-state. In this connection, the detection switch 82 self-maintains the ON state, stably puts the engine 1 into the non-operating state, and the operation of the preparation device C is stopped. Accordingly, no further spherical portion t3 is sent into the discharge shooter 70, and further clogging in the processing unit C2 and the discharge shooter 70 is reliably prevented.

  When the engine 1 is deactivated in this way, the operator removes the spherical portion t3 clogged in the discharge shooter 70 from the open portion, and the spherical portion t3 clogged in the processing unit C2. Remove. At this time, since the clogging of the spherical portion t3 in the discharge shooter 70 is in the initial stage, the spherical portion t3 in the discharge shooter 70 can be easily taken out from the open portion, and the spherical portion t3 in the processing unit C2 is Since there is no clogging in the upstream portion to the extent that it is clogged on the receiving rod 69, the spherical portion t3 that is clogged in the processing unit C2 is often the case. Further, it can be easily taken out through the opening portion of the discharge shooter 70 without removing the cover member. On the other hand, onions are not damaged.

  Here, when it is desired to detect clogging in the discharge shooter 70 earlier, the detection switch 82 is adjusted so that the fixed height is lowered. On the other hand, when it is desired to detect it later, the fixed height of the detection switch 82 is adjusted. It is adjusted to increase the height.

  After the spherical portion t3 clogged inside the discharge shooter 70 and the processing unit C2 is removed, the input portion 82a of the detection switch 82 is rotated through an open portion formed on the side surface of the receiving portion 70A. The held on state is released to return to the cut state, whereby the input portion 82a is returned to the original position, the detection switch 82 is in a detectable state, and the engine 1 is in an operable state. Thereafter, the operator restarts the engine 1 and restarts the preparation process.
