The operation of the embodiment in which agricultural products are used as potatoes will be described.
The farm work machine G is run along the ridge of the field by operating the crawler wheel G ₁ . Excavated potatoes are placed on the surface soil of the ridge, dried in the sun.
An endless slat conveyor N ₁ is provided at the tip of the agricultural work machine G, and the tip end thereof is inserted so as to be inserted obliquely into the field soil, and the body G ₂ travels while the endless slat band N ₁₁ is fed. As a result, the endless slat conveyor N ₁ scoops together potatoes, pebbles, and a lump of soil placed on the field by the traveling of the aircraft, and moves them diagonally upward by the endless slat band N ₁₁ . During this time, small lumps, pebbles, small potatoes, etc. fall from between the slats N ₁₂ onto the field below.
The potatoes moved upward in the endless slat band N ₁₁ are further lifted by the lifting conveyor N ₂ and put into the pallet circulation conveyor S.

The put potatoes, lumps, stones, etc. are placed on the pallet S ₁ of the pallet circulation conveyor S and sent along the square-shaped conveyor. Outside the pallet circulation conveyor S, three chairs C attached to the machine body G ₂ are provided, and an operator rides on the chair C and is sent by the pallet circulation conveyor S to a stone other than a good potato.・Scraps of plant bodies such as soil blocks, leaves, roots, etc. and defective agricultural products are manually pinched and discharged to the field outside the machine. Or, discharge it to the trash box placed on the machine.

In this way, when the potatoes are sent to the belt conveyor F, which is a crop feeding device, after the pallet circulation conveyor S selects and discharges the waste, the vertical belt surface of the endless belt F ₁ of the belt conveyor F is conveyed. Then, it is guided in the feeding direction of the belt surface and dropped by the fall guide F ₁₀ into the square-shaped inner space of the pallet circulation conveyor S.

On the other hand, there is a box installation device H in the central space of the pallet circulation conveyor S, and an empty collection box B is sent from an empty box feeding chute plate H ₁ on the lower right side where the belt conveyor F is located, and the box installation device H is sent. It fits within the box support frame H ₂ of H.
After that, the foot lever H ₂₆ is stepped on by the foot to release the horizontal maintaining claw H ₂₅ from the locking pin H ₂₇ .
Then, the urging cylinders _{H 24} is pushed up a box supporting frame _{H 2,} a box support frame _{H 2} is rotated about the upper pivot shaft _{H 230} of the mounting arm _{H 23,} it is held at an angle state. The upper opening of the collecting box B in the box supporting frame H ₂ is inclined so as to face the direction of the drop guide F ₁₀ (see FIG. 3).

Therefore, the potatoes guided from the belt conveyor F and falling by the drop guide F ₁₀ are dropped into the upper opening of the inclined collection box B and are stored therein.
When many of the stored potatoes enter the recovery box B, the load due to the weight thereof resists the lifting torque of the urging cylinder H ₂₄ and rotates horizontally to move the recovery box B and the box support frame H ₂ in the horizontal direction. The posture (see FIG. 4). When it is horizontal, an alarm sound of a buzzer (not shown) is generated. With this, the belt conveyor F is rotated, the manual operation lever F ₈ is engaged with the lever holding clamp F ₉ , and the belt conveyor F is held at the retracted position. By setting this position, it is possible to prevent the agricultural products from falling into the central space, the time until the empty collection box B is installed in the box installation device H, and the agricultural products on the pallet S ₁ are the pallets of the pallet circulation conveyor. It sits on top of S ₁ and does not patrol and fall. After the empty collection box B is installed in the box installation device H, the belt conveyor F is moved from the retracted position to the oblique position. As a result, the fall of agricultural products starts.

When the box support frame H ₂ becomes horizontal, the horizontal maintaining claw H ₂₅ is locked to the locking pin H ₂₇ , and the box support frame H ₂ is fixed.
In this state, the collection box B is slightly lifted at the rear part, the auxiliary roller H ₂₈ is slid, and the collection box B is pulled out to the outside of the pallet circulation conveyor S. The withdrawn collection box B is placed on the field or the aircraft G ₂ is placed.

When the collection box B is full and pulled out from below the central space, the empty collection box B on the next ceiling shelf T is moved from the empty box feeding chute plate H ₁ into the box support frame H ₂ below the central space. Send in. Then, the belt conveyor F is returned to the oblique position.

On the outer circumference of the square-shaped pallet circulation conveyor S, three workers can be arranged to sort potatoes and to sort wastes (such as soil blocks, defective crops, stones). In addition, the traveling driver of the crawler vehicle G ₁ of the agricultural work machine travels slowly and can perform the sorting work.
Therefore, three workers can sit on the chair C and work, and even if the picking-up speed of the potatoes is increased, it is possible to secure the sorting work ability corresponding to the picking-up speed.

Moreover, since the recovery box B can use the space below the center of the pallet circulation conveyor S, the installation space of the recovery box B, the space for dropping potatoes, and the roller space for loading and unloading the recovery box are not secured on the left and right sides of the pallet circulation conveyor S. Therefore, it is possible to secure a space for arranging a large number of chairs for workers on the outer periphery of the three sides of the pallet circulation conveyor S, and to improve workability.

Next, by providing the ceiling shelf T above the central space of the pallet circulation conveyor S, a large number of empty lightweight recovery boxes B can be loaded and moved.
Moreover, by the provided struts T ₁ for supporting the ceiling shelf T inside the pallet circulating conveyor S, gone worker outer posts hand has been a hindrance easily contact, the movement of the hand work Enables a wide range and enhances work ability.

In addition, in this embodiment, the left and right sprockets N ₁₄ above the endless slat conveyor N ₁ of the crop picking device N are provided with the extruded material N ₁₄₂ at a position between the grooves N _{141 with which} the rod-shaped slats N ₁₂ engage. As a result, vine fragments, stones, clods, etc. sent in the endless slat zone N ₁₁ tend to become jammed or stuck between the slats N ₁₂ at the position of the sprocket N ₁₄ , but the slats N ₁₂ During this period, the extruded material N ₁₄₂ pushes out the clogging/adhered matter between the slats N ₁₂ to the outside, thereby eliminating the clogging/adhered matter at the upper sprocket N ₁₄ and the potatoes by the endless slat band N ₁₁ . Along with picking up, it enhances the ability to remove small pebbles, clods, and plant debris.

As described above, according to the present embodiment, it is possible to perform the work of selecting the picked-up potatoes and removing the waste with high efficiency. In addition, the holding of the empty collection box and the putting in and out of the collection box B containing the agricultural products were facilitated.
Also, the impact of falling potatoes from the pallet circulation conveyor S to the collection box B can be softened by making the collection box B initially slanted high and gradually descending, and scratches can be reduced.
