Since the width of the conveyor is approximately equal to the width of the crop, by repeating the above-described feeding operation, the crops that overlap each other are collapsed and leveled, and at the end of the conveyance, there is one layer on each conveyor. Only one crop is placed on the table. As a result, even if a plurality of crops to be conveyed are superimposed and fed from the upper side of the conveyance, at the end of the conveyance, they are always sent one by one to the next process. Moreover, the vertical movement of each transport body only requires consideration of the timing of movement of adjacent transport bodies, and a simple drive structure is sufficient. Furthermore, when the crops to be transported temporarily remain, the amount of the crops to be transported in the progressive loading and conveying device increases, and this is detected by the crop amount detection means, and the feed speed of the unloading section is adjusted accordingly. For example, by slowing down, the amount of transferred crops to the progressive loading and conveying device is limited, thereby preventing clogging.

It was now possible to continue transportation.

れることになる。The alignment conveyance section 4 has an upper crop mounting surface 15a having approximately the same width as the width of the crops A to be conveyed, and is configured in an inclined position such that the lower side in the conveyance direction of the crops A to be conveyed is located lower. A plurality of conveyors 15 are arranged in parallel along the conveyance direction of the transported crops A, and a drive mechanism 16 is provided to move each conveyor 15 up and down at a predetermined pitch. The drive timing is set so that it moves up and down. In other words, as shown in Figure 2,
A plurality of conveyors 15 are arranged in parallel along the conveyance direction, and the odd-numbered conveyors 15 are configured to be integrally driven in reciprocating vertical motion at a constant pitch as a first group, and the even-numbered conveyors 15 are arranged as a first group. The two groups are configured to be integrally driven in reciprocating vertical motion. And each carrier 15
A crankshaft 17 is provided below the crankshaft 1.
7, each carrier 15 is interlocked and connected via each crank rod 18, so that when the first group of carriers 15 is moving upward, the second group of carriers 15 moves downward. The drive mechanism 16 is configured by setting the drive timing of the filter. Therefore, the transported crops A sent from the carrying out section 3 through the guide chute 19 are transferred to the crop mounting surface 15 in the inclined attitude as the transporting body 15 moves upward.
a, the crop A is transferred to the transport body 15 on the downstream side in the transport direction, and such transfer movement is repeated in sequence to transport the crop A to be transported. At this time, the transported crops A placed on the downwardly moving transporter 15 before being transferred to the next transporter 15 are received and supported by the front surface of the next transporter 15, so that the transported crops A are separated. will be ensured. Moreover, since the loading width of each conveyor 15 is approximately equal to the width of the transported crops, if such transfer movement is repeated multiple times, two or more overlapping transported crops A will be leveled into one piece at a time. , at the end of the conveyance, the pieces are reliably sent out one by one.

Based on the detection result of this crop quantity detection means, the carrying out section 3
The apparatus is equipped with an unloading speed control means for changing and controlling the conveying speed of the conveyor. More specifically, as shown in FIGS. 1, 2, and 4, the light emitted by the light emitter 20a is passed from above through the gap between each of the carriers 15, and the light is passed through the light receiver disposed below. An optical sensor S is provided as a crop amount detection means for detecting the amount of crops A to be transported based on the state of interruption of the light by receiving light from the light sensor 20b. , counts the number of times the light is interrupted from the detection signal of the optical sensor S, calculates the transport amount of the transported crop A, and controls the rotational speed of the driving electric motor 22 of the unloading section 3 based on the calculation result. It is configured to do so. In other words, when the amount of transported crops A in the alignment conveyance section 4 increases, the transport speed of the unloading section 3 is slowed down to prevent the transported crops A from stagnation and to prevent transportation obstruction due to clogging. be.
