According to the invention 請 Motomeko 1 according to the present invention, the drilling body first
While the harvested products are sequentially loaded onto the conveyor of No. 1,
From the carry-out end of the first conveyor to the carry-in end of the second conveyor
Are sequentially loaded into the department, and the harvest is collected on this second conveyor.
These crops are transported to the delivery department one after another,
They are sequentially stored in the storage section from the carry-out end of the Nbeya.

At this time, the carry-out end of the first conveyor and the second conveyor
Exclude non-harvested material between the conveyor's carry-in end
Since the space is formed, it is
Once the non-harvested items have been delivered, these non-harvested items are transferred to the first
Discharge between the discharge end of Beya and carrying end of the second con Beya
It can be reliably excluded from the removal space.

Therefore, when the harvested product is transported,
Secured in the exclusion space without being loaded onto the second conveyor
By being eliminated, the first on the second conveyor
Only the crops carried out from the carry-out end of the conveyor of
The storage section stores non-harvested items other than harvested items.
Can be reliably prevented.

[0072] Further, since the elimination space was adjustable spacing, for example, by adjusting the distance exclusion space in consideration of the size of the crop for shipment in accordance with market conditions, for shipping eliminating space It can be easily adjusted to the interval according to the size of the harvested product, and the harvested products having a size larger than this exclusion space can be sequentially carried in from the first conveyor to the second conveyor for shipping, and the predetermined size for shipping can be set. Non-harvested products other than harvested products smaller than the size can be reliably excluded from the exclusion space without being carried on the second conveyor.

According to the invention of claim 2 , in addition to the effect of the invention of claim 1 , the exclusion space is composed of the first conveyor and the second conveyor.
One of the first conveyor and the second conveyor in consideration of the size of the harvested product for shipment according to market conditions, etc. By moving, the exclusion space can be easily adjusted to an interval that matches the size of the harvested product for shipping.
Can be sequentially loaded from the conveyor of the above onto the second conveyor for shipping, and surely removes non-harvested products other than the predetermined size for shipping from the exclusion space without carrying them onto the second conveyor. You can

According to the invention of claim 3 , in addition to the effect of the invention of claim 1 , the exclusion space is rotatable between the carry-out end of the first conveyor and the carry-in end of the second conveyor. Since the spacing is adjusted by the vertical movement of the provided guide roller,
For example, by moving the guide roller up and down in consideration of the size of the harvested product for shipment according to the market conditions, etc., it is possible to easily adjust the exclusion space to an interval according to the size of the harvested product for shipment. Harvested products having a size larger than the exclusion space can be sequentially carried in from the first conveyor to the second conveyor via the guide rollers for shipping, and non-harvested products other than the harvested product smaller than the predetermined size can be secondarily shipped. Can be guided to the guide roller without being carried onto the conveyor and can be reliably excluded from the exclusion space.

According to the invention of claim 4 , from the excavated body to the first
The harvests are sequentially loaded onto the conveyors of
From the carry-out end of the first conveyor to the carry-in end of the second conveyor
Are sequentially loaded into the store, and the harvest is stored on this second conveyor.
Are sequentially transported to the department and these crops are
The carrier is sequentially stored in the storage portion from the carry-out end portion.

At this time, the carry-out end of the first conveyor and the second conveyor
Exclude non-harvested material between the conveyor's carry-in end
Since the space is formed, it is
Once the non-harvested items have been delivered, these non-harvested items are transferred to the first
Discharge between the carry-out end of the bayer and the carry-in end of the second conveyor
It can be reliably excluded from the removal space.

Therefore, the non-harvested material is
Secured in the exclusion space without being loaded onto the second conveyor
By being eliminated, the first on the second conveyor
Only the crops carried out from the carry-out end of the conveyor of
The storage section stores non-harvested items other than harvested items.
Can be reliably prevented.

Further , the first conveyor and the second conveyor each have an endless rolling member on which a harvested product is placed and conveyed rearward, and the endless rolling member of the second conveyor is the first
Since it travels at a speed faster than the traveling speed of the endless traveling body of the conveyor, it goes upward from the retracting side of the endless traveling body of the first conveyor to the upper side of the endless traveling body of the second conveyor in the exclusion space. Since the discharge side, which is turned around by turning back and forth, is turned around at a high speed, the harvested product can be smoothly carried onto the endless moving body of the second conveyor without being stagnated in the exclusion space part, and can be mistakenly handed into the exclusion space. Etc. can be prevented from being drawn in.

Further, when non-harvested products other than harvested products are carried onto the endless traveling body of the first conveyor, these non-harvested products are transported to the second end and the second end of the endless traveling body of the first conveyor. Can be more reliably excluded from the exclusion space formed between the conveyor and the carry-in end of the endless traveling body.
