However, in the above-mentioned proposed technique, since a container for collection is provided after the leaf cutting device and the crop is dropped and collected in the container, the crop may be damaged by the drop. there were.
In particular, it is thought that the drop height is high in the initial stage of recovery, and the danger is prominent. Therefore, it is conceivable to reduce the above-mentioned risk by making the bottom of the collection container shallow and lowering the falling height. However, this method has a disadvantage that the amount of collected crops is reduced. An object of the present invention is to realize a collection device that does not damage crops and does not reduce the collection amount while following the collection means by drop transfer.

According to the above-mentioned characteristic configuration, at the time of starting the collection of agricultural products, the urging action of the elastic member 37 causes the container 13 to swing upward around the fulcrum X as shown in FIG. Be energized. In this state, the crops sent from the previous process slide down on the side wall 13a of the container 13 and are transferred, so that the impact due to the collision with the bottom 13b of the container 13 can be reduced, and the conventional method can be used. The drop impact is significantly reduced as compared with the means for dropping. When the amount of collection in the container 13 increases, the container 13 automatically turns downward around the fulcrum X due to the increase in its own weight, so that the already collected crops are not obstructed, and The crop can be continuously collected while maintaining the state of the sliding transfer by the gentle slope formed on the upper surface. Then, as shown in FIG. 4, when the container 13 is almost full, the container 13 is almost in an upright recovery position, and the container 13 can be sufficiently filled with agricultural products. As described above, by setting the elasticity of the elastic member 37, the crop can be collected in the state of being slid and transferred regardless of the depth of the container 13, so that the depth of the container 13 can be made deeper than in the past. It will also be possible to increase crop yields. In addition, it is also possible to shorten the overall length of the harvester without reducing the amount of collected crops by reducing the front and rear width of the container and increasing the depth. By the way, in order to change the attitude of the container 13 with the increase in the amount of harvested crops as described above, for example, a collection amount detection sensor such as an optical type that counts the number of crops fed into the container 13 and a fulcrum X are used. It is possible to provide a potentiometer for detecting the inclination posture of the container, and to control the inclination posture of the container 13 appropriately by driving an actuator such as a hydraulic cylinder based on the detection information of the sensor while feeding back the inclination posture. While the structure is complicated and expensive, the structure of the present application suffices to provide a simple and inexpensive means simply by providing appropriately set elastic members.

[Effects of the Invention] As a result, the incline attitude of the container is changed according to the amount of the harvested crop by the elastic member, so that the crop is not damaged, and the harvested crop is not damaged while following the recovery means by economical drop transfer. It was possible to provide an inexpensive collection device without reducing the amount of the device, with a simple structure.

Next, the leaf cutting section B will be described in detail. The conveyor 7 includes a plurality of rotatable rollers 31 arranged side by side at predetermined intervals between adjacent ones, and a chain formed by connecting chain links attached to ends of the plurality of rollers 31. 32 is wound around four front and rear sprockets 33, and the root vegetables sent from the lifting and conveying device 3 are transported rearward while lying down. A guide member 34 is provided in contact with the lower surface of the roller 31 in the upper roller portion. When the chain 31 is driven to revolve in the direction of arrow A, the guide member 3
The roller 31 that comes into contact with the roller 4 also rotates in the counterclockwise direction (the direction of arrow B in the drawing). As shown in FIG. 5, a brim 31a is attached to the left end of the roller 31, so that the root vegetable body can be aligned with the brim 31a. The aligning device 8 is provided above the conveyor 7 with a rotating brush 35 that rotates around an inclined axis T whose front portion is inclined to the right with respect to the axis V of the roller 31.
And has the function of sequentially moving the leafy side of the root vegetable in the reclined posture to the brim 31 a of the roller 31. That is, the rotating brush 35 elastically contacts the upper surface of the root vegetables to generate a feed force for forcibly transferring the root vegetables to the left in the drawing, so that the root vegetables can be reliably brought into contact with the brim 31a and aligned. It is like that. The leaf cutting device 9 is provided with a rotary blade 36 that rotates around the left and right axes at the rear of the conveyor 7 and is adapted to transfer root vegetables transferred in a predetermined cutting posture in which the root vegetable body is abutted on the brim 31a. The leaves are cut at the base. The pre-processing cutter 10 is driven and rotated around the horizontal axis, is mounted at a position slightly leftward from the roller 31 at the front of the conveyor 7, and is a leaf portion of the root vegetable sent from the lifting conveyor 3. The leaves are grown in all directions so that they do not adversely affect the subsequent steps.

The recovery section C will be described in detail. As shown in FIGS. 3 and 4, the collection container 13 stores the root vegetables of only the main body whose leaves have been cut. A tension spring 37 is provided for urging the empty collection container 13 to an initial posture (the state shown in FIG. 3) inclined about the horizontal axis X so that the front side wall 13a becomes a ginseng sliding surface. The collection container 13 swings around the horizontal axis X as the ginseng weight increases with the progress of the ginseng collection into the collection container 13 and automatically changes to the upright collection posture (the state of FIG. 4). The elastic force of the tension spring 37 is set as described above. As a result, the ginseng that slides on the side wall 13a comes into gentle contact with the bottom 13b of the collection container 13, thereby preventing the ginseng from being damaged by the transfer to the collection container 13. Reference numeral 39 denotes a rotary hook that holds the collection container 13 in the upright collection posture regardless of the collection amount. still,
In this embodiment, a pre-processing unit A, a leaf cutting unit B, and a harvesting unit 0 are configured.
