Description

[Detailed description of the invention] This invention relates to a reaper, such as a soybean reaper, which has a cutting blade and a cut crop conveying belt extending rearward from the cutting blade. It consists of a main conveyance belt for conveyance and a sub-conveyance belt arranged below for conveyance of weeds, etc., and the sub-conveyance belt forms a conveyance path with an angle between it and the main conveyance body to remove weeds. This relates to a reaping machine that can carry out items such as the following from outside the main conveyance system.

In general, there are various types of reapers depending on the type of crop to be harvested, and for example, one suitable for soybean reaping work has a cutting blade section at the front of the machine body, and a section extending from the cutting blade section to the rear to transport the harvested crops. There is an embodiment in which a belt is provided and a crop harvesting box is provided at the rear end of the belt.

However, the above-mentioned trailing conveyor belt type reaper has the disadvantage that it also conveys cut weeds, fallen leaves, straw, etc. along with the crops. In the case of a type with a harvest box, there is a disadvantage that weeds etc. get mixed into the harvest box, making it difficult to separate the crops with a reaper. If cut weeds, etc. get wrapped around the wheels, or
It had disadvantages such as wrapping around other rotating mechanism parts and causing trouble in the aircraft's drive.

The object of this invention is to provide an excellent harvester that has overcome the problems associated with the above-mentioned conventional technology, by providing a sub-carrier for transporting weeds, etc. below the main conveyor belt for transporting crops, so that weeds, etc. can be transported separately, and by enabling the weeds, etc. to be transported to the side of the machine via a separate route, thereby eliminating the above-mentioned drawbacks and eliminating the disadvantages and inconveniences.

The structure of this invention, which meets the above objectives, is that when harvesting soybeans, etc. while the machine is moving in the field, the harvested crops are transported later by the main conveyor belt and left in the field or placed in harvest boxes. On the other hand, the cut weeds, etc. are transported by a separate route below the transport route of the cut crops, and are laterally released to a different part from the abandoned harvest area of the cut crops, Prevent weeds from entering the harvest,
The gist of this is that the width of the aircraft can be made narrower when driving on the road to fields.

Next, an embodiment of this invention will be described below based on the drawings.

1 is a soybean harvester based on this invention,
An engine 3 and an operating section 4 are provided behind the wheels 2, and a weeding section 5 is provided at the forefront of the machine body, a cutting blade 6 is provided at the rear thereof, and a conveyance section 7 is provided above it.

The conveyance section 7 is provided with a main conveyance belt 9 extending backward from the weeding body 5 and whose rear end faces above the rear harvest box 8, and below the main conveyance belt 9, and whose entire length is the main conveyance belt 9. It consists of a sub-transport belt 10 that is less than 1/2 of the transport belt.

The main conveyor belt 9 includes a front pulley 11 and a rear idler pulley 12, which are rotated by the output of the engine 3.
The claw 14 and rail 15 of the belt 13 hung on the
The sub-transport body 10 has a front portion driven coaxially with a front pulley 11 of the main conveyance belt 9. Weeds and the like can be transported only by the rotating force of the claws 18 of a short belt 17 without rails, which is hung between the pulley 11 and the rear floating pulley 16.

As shown in FIG. 3, the sub-conveyance belt 10 is designed to be able to rotate inward and outward on a substantially horizontal plane about the axis of the front pulley 11', and the angle α with respect to the main conveyance belt 9 is can be set arbitrarily and fixed with elongated holes, bolts, etc. as appropriate.

In addition, 19 is soybean which is a reaped crop.

In the above configuration, when harvesting the soybeans 19, the auxiliary conveyance belt 10 is rotated laterally and extended in advance with respect to the main conveyance belt 9 by a set angle α, and fixed appropriately, and the wheels 2 are driven by the output of the engine 3. Therefore, as the machine moves forward, the cutting blade 6 operates to harvest the soybeans 19 in the field, which are then transported later by the gripping action of the claws 14 and rails 15 of the main conveyance belt 9 and stored in the harvest box 8. .

As the soybeans 19 are harvested, weeds and the like are also harvested, but since the mowed weeds, straw, etc. are present at the base of the soybeans 19, they do not reach the height of the conveyance path by the main conveyance belt 9. Only the claws 18 of the wide conveyance belt 10, which is located below and has no rails, are rotated and separately conveyed laterally and released onto the field.

Therefore, by arbitrarily setting the conveyance path angle α of the sub-conveyor belt 10 before reaping, only weeds etc. can be discharged to the side of the machine, and thereby the soybeans 19 in the harvest box 8 are Contamination is prevented, and discharge does not impede the progress of the aircraft.

After the work, the sub-conveyance belt 10 is stored and fixed in parallel to the lower part of the main conveyance belt 9, similar to when the machine is brought into the field, thereby reducing the width of the machine.

Note that the embodiment of this invention is not limited to the above embodiment, and can be designed in other embodiments. For example, the harvest box 8 may be omitted and the crops transported by the main conveyance belt may be released into the field at the rear of the machine. It goes without saying that weeds and the like may be discharged to a separate field by the sub-transport belt 10 to prevent them from being mixed with each other.

As described above, according to this invention, in a reaper having a cut crop conveyance belt extending backward from the cutting blade part, the cut crop conveyance belt is disposed below the main conveyance belt having a rail and a claw that acts as a conveyor. Since it consists of a sub-transport belt that does not have rails, cut crops and weeds, straw waste, etc. are transported along a separate route, which has the effect of preventing weeds from getting mixed in with the harvest of the cut crops.
In addition, since weeds and other impurities are scraped off during the initial stage of transportation of harvested crops, only the culms of the crops are securely clamped and transported, which prevents weeds from falling during transportation, or weeds falling during transportation. Therefore, the phenomenon that the clamping pressure changes and the stocks become uneven does not occur.

Furthermore, the sub-conveyance zone is rotatable laterally via the front pulley and can be set at a predetermined angle with the main conveyance zone, so that weeds and the like are moved in a different direction from the harvested crops, for example. Since it can be discharged to the side of the machine, it is possible to avoid contamination with harvested crops, and it also prevents weeds from getting wrapped around the rotating parts and wheels of the machine, making it extremely safe. When stored, the main and sub-carrying belts are set parallel to each other to reduce the width of the machine, making it more compact.This also has the advantage of increasing safety.
