During the operation of the farm work machine 1, the onion T with the foliage T2 taken out from the container 5 onto the supply means 7 by the operation of the take-out means 6 is conveyed by the supply means 7 in the conveying direction a. Then, the sheet is supplied to the transport start end side of the transport means 8.

The plurality of onions T supplied to the starting side of the conveying means 8 are conveyed in the conveying direction B by the vibration of the conveying means 8 itself, and the entwined foliage T2 of the adjacent onions T is loosened and guided. It is guided in the groove 50 and is arranged in a plurality of rows while being separated one by one.

At this time, the rotating plate 79 of the rotating body 75 on the conveying end side.
However, the movement of the onion T in the transport direction b is regulated so that the onion T is slightly moved upward and the brake is applied, and the onion T is once arranged in parallel on the guide groove 50 along the transport direction b. That is, the onions T are arranged adjacent to each other on the guide groove portions 50 by the braking action of the divided rotating plate portions 82 of the rotating plate 79.

Then, the rotating plate 79 of the conveying terminal side rotating body 75 is further rotated upward by the pressure of the onion T, whereby the onion T is discharged from each of the divided rotating plate portions 82 one by one. The discharged onion T is brought into contact with the row number reducing section 53 to change its direction, and then is delivered onto the conveyance start end of the corresponding cutting unit 91 of the cutting means 9.

The onion T delivered onto the transport start end of the cutting unit 91 is transported in the transport direction c while the foliage portion T2 is directed downward, and then sandwiched by the disc blade 94 and the receiving plate 95. Thus, the foliage portion T2 is cut and removed.

The onion T from which the foliage T2 has been removed
After being lifted and conveyed by the lifting and conveying means 10, it is supplied onto the sorting and conveying means 11 and, during the conveyance by the sorting and conveying means 11 in the conveying direction D, a sorting operation is performed by an operator.

The onion T conforming to the standard is a good product conveying means 14
Passing through the space conveyor 115 from the downwardly inclined turning chute 102 located at the working position, and then into the non-defective container 15 supported by the container supporting means 121 set to the working state. It falls and is stored in the container 15 for non-defective products.

At this time, for example, as shown by the chain double-dashed line in FIG. 7, the side support 1 supported by the base 124 in the advanced state.
31 supports the side surface of the non-defective container 15 in an inclined state in which the rod 139 of the cylinder 137 has advanced upward, and supports the side surface of the non-defective container 15 and intersects with the side surface support 131. Supports the lower surface of the container 15 for non-defective products, and as a result, the container 15 for non-defective product is supported by the cross-shaped side surface support 131 and the lower surface support 133 in an inclined shape at a position relatively distant from the field. Therefore, the fall distance of the onion T falling from the rotating chute 102 is relatively short, and the onion T is not damaged.

Then, as the work progresses, the worker
The rod 139 of the cylinder 137 is gradually retracted by operating an operating means (not shown) according to the storage amount of the onion T, and the side support 131 and the lower support 133 of the container support 121 intersecting each other are rotated. Is rotated downward around the center, and finally, as shown by the solid line in FIG. 7, the non-defective container 15 is horizontally supported at a position relatively close to the field by the container support means 121.

Then, the operator operates the operating means (not shown) to switch the conveying direction of the belt conveyor 101, and then unloads the container 15 for good products, which is full with the onion T, from the container supporting means 121, and instead replaces the empty good products. The container 15 is placed and set to the initial tilted state.

At this time, the container 15 for non-defective products is loaded and unloaded on the container support means 121 by a forklift not shown, but the base body 124 is in an advanced state with a predetermined advance distance, and the side support bodies 131 intersect each other.
Since the lower surface support 133 is located at a position slightly away from the side edge of the machine casing 2, the forklift for loading and unloading while moving along the front-rear direction of the agricultural working machine 1 does not interfere with the machine casing 2 or the like. .

On the other hand, non-standard onion T (long ball, rotten ball, peeled ball, deformed ball, etc.) is a chute of defective product conveying means 16.
Belt conveyor through 104a and contact chute 104b
It drops from 105 toward the defective product container 17 and is accommodated in the defective product container 17.

Here, the amount of the onion T taken out onto the supply means 7 by the operation of the take-out means 6 is not constant, and, for example, an amount of onion T exceeding a predetermined amount is taken out onto the supply means 7. In this case, as shown in FIG. 1, the onions T are stacked in a plurality of stages in the storage section 62 of the transport means 8, and the transport start end side rotating body 61 is pushed by the onions T to move upward. When the set angle is turned to 1, the detection means 71 is turned on and a detection signal is output to the control means 72. Then the control means
The supply means 7 is stopped by the control of 72, and the onion T is not supplied to the transport means 8 by the supply means 7. Reservoir
The onion T stored in a plurality of stages on the 62 is a rotating body on the transport start end side.
By the braking action of each of the divided rotary plate portions 70 of the rotary plate 67 of 61, the rotary plate 67 moves in the conveying direction b in one step.

When the amount of the onion T in the storage section 62 is reduced to some extent, the transport start end side rotating body 61 rotates downward by its own weight, and the detecting means 71 is turned off. Then, the supply means 7 is operated by the control of the control means 72, and the supply of the onion T to the transport means 8 by the supply means 7 is restarted. In this way, the supply means 7 operates intermittently in conjunction with the detection means 71,
The amount of onion T on the conveying means 8 is kept constant. That is, the detection means 71 automatically supplies a fixed amount, and a small number of people work.

On the other hand, when the farm work machine 1 is moved from the field to the storage location such as a warehouse after the work is completed, for example, the worker uses the belt conveyor 105 of the defective product carrying means 16 as a machine frame. 2 and the container 15 for good products is unloaded from the container support means 121,
First, as shown in FIG. 8, the rod 139 of the cylinder 137 is slightly retracted to set the base body 124 in the retracted state, and the side support 131 and the lower support 133 are slightly approached to the side ends of the machine casing 2. Let

Subsequently, the operator manually operates the corresponding rotating chute 102 as shown in FIG.
After being folded to a position above the end of 01, while bending the connecting arm body 135, the lower surface support body 133 is rotated upward about the rotation shaft 134 so as to be folded with respect to the side surface support body 131 to support the side surface. It is set in a parallel state in which it is parallel to the body 131.

Then, as shown in FIG. 10, the retracted base body 124 and the side support 131 and the bottom support 133 which are parallel to each other are positioned inside the outer ends of the wheels 3, that is, on the machine frame 2 side. State, that is, container support means
121 is moved to the position near machine frame 2 and is in a non-working state,
Therefore, the side support 131 and the lower support 133 do not interfere with the movement of the agricultural work machine 1 itself.

The lower surface support 133 may be set in the parallel state and then the base body 124 may be set in the retracted state. To return the container support means 121 to the working state, for example, the lower surface support body 133 is set to the crossing state and then the base body 124 is set to the advanced state, or the base body 124 is set to the advanced state. The lower surface support member 133 is set in an intersecting state.

As described above, according to the above-described embodiment, the base body 124 of the container supporting means 121 can be set in the advanced state at the time of working, and the lower surface support body 133 and the side surface support body 131 are positioned in an intersecting shape. Can be set to the state, the base body 124 can be set to the retracted state when not in operation, and the lower surface support 133 can be set to a parallel state in which the lower surface support 133 and the side surface support 131 are parallel to each other, so that the onion T is prevented from being damaged during work. Moreover, the onion T can be properly accommodated in the non-defective container 15 while preventing the farm work machine 1 from interfering with the forklift, and the container supporting means 121 can be arranged inside the outer end of the wheel 3 when not in operation. For example, the agricultural work machine 1 can be easily moved to a storage place such as a warehouse, and the agricultural work machine 1 can be easily carried by a carrier vehicle such as a truck.

Further, since the common cylinder 137 for advancing / retreating the base body 124 and rotating the side support 131 is provided, the advancing / retreating drive means for advancing / retreating the base 124 and the side support 31 are rotated. The configuration can be simplified and the manufacturing cost can be reduced as compared with the configuration in which the rotating drive means for moving is separately provided.

Furthermore, a container for non-defective products by transporting the onion T
Since it is possible to fold the rotating chute 102 that is dropped toward the inside of the 15, it is possible to prevent the rotating chute 102 from interfering with the transportation and movement of the agricultural work machine 1 itself when not in operation.

Further, the control means 72 controls the drive motor 33 of the supply means 7 according to the rotation of the conveyance start end side rotating body 61 in the upstream portion of the conveyance means 8 to supply the onion T by the supply means 7. Because of the limitation, it is not necessary for an operator to manually monitor the amount of agricultural products and manually operate the supply means 7, and a quantitative flow of the onion T on the carrier 41 of the carrier means 8 can be easily realized.

Further, a quantitative flow of the onion T can be realized more surely by the step number reducing function based on the braking action of the conveyance starting end side rotating body 61, and therefore the conveying means 8
Thus, the entanglement of the foliage T2 of the onion T can be surely disentangled, and the cutting means 9 can be properly aligned for cutting. Further, the sorting and conveying means 11 located downstream of the conveying means 8
The uniform transport of the onion T by means of the above allows the waste-free sorting work.

Furthermore, the parallel function based on the braking action of the conveying end side rotating body 75 at the downstream portion of the conveying means 8 stabilizes the onion T from the conveying end portion of the conveying means 8 toward the conveying start end portion of the cutting means 9. Can be sent to. Therefore,
For example, the onion T etc. that slipped from the transport start end side rotating body 61
It is possible to prevent the cutting means 9 from rolling vigorously or being sent to a position other than the transport start end portion of the cutting means 9, and the cutting means 9 can appropriately cut the foliage portion T2.

Further, since the transport end side rotary body 75 has a plurality of divided rotary plate portions 82 located corresponding to the guide groove portions 50, for example, the transport end side rotary body 75 is a single sheet. It is possible to prevent the onion T from being adversely affected by the difference in the size of the onion T, as compared with the case where it is configured by the rotating plate. Therefore, for example, when a relatively large onion T moves on the one guide groove 50, the flow of the onion T on the other guide groove 50 adjacent to the one guide groove 50 becomes fast. Etc. can be prevented.

The side support 1 of the container support means 121
The lower surface support 133 may be rotated about the rotation shaft 134 with respect to 31 by the drive means. Further, the downward rotation of the cross-shaped side surface support member 131 and the lower surface support member 133 about the rotation shaft 132 at the time of work is automatically performed by a signal of a detection unit that detects the storage amount of the onion T. It may be performed.
