Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pick-up device for a harvester which can pick up crops such as potatoes and onions on the ground or in the ground accurately and can efficiently perform the harvesting work.

[0002]

2. Description of the Related Art For harvesting agricultural products such as potatoes and onions, it is desirable to harvest a large area in a short time in good weather because the weather is good and the dryness of the field can be monitored. For this reason, a harvester equipped with a pick-up device that can harvest a large number of ridges of agricultural crops at once is adopted in terms of harvesting efficiency.

For example, in the case of an onion, its ridge width is usually 2
It is about 7 to 30 cm, and is generally equipped with a pick-up device that harvests four rows at a time. In contrast to the 4 articles, if the 8 articles are equipped, the yield efficiency is doubled in calculation, but as shown in FIG. 5, it is necessary to configure the conveyor b of the pick-up device a to be about double the length. is there.

[0004]

In the case of working with a harvester equipped with a pick-up device a having such a long conveyor body b construction, smooth harvesting can be carried out in a flat field without any problems. However, if the field is tilted or uneven, there are the following drawbacks. The reason for this unevenness is that after the crops are transplanted, the spraying of the chemicals and the watering work are carried out.When a working machine or a tractor enters the field, the ground pressure is pushed by the ground pressure of tires, etc. Is uneven.

If there is a convex portion T in the field scene, a large amount of the soil mass of the convex portion T enters the conveyor body b together with the agricultural products N, and a load is applied to the conveyor body b, causing bending or damage. To prevent this, the horizontal rod c of the conveyor b
It is necessary to improve the durability of the conveyor body b by increasing the cross-sectional area of the conveyor body b.

The presence of the recess U increases the distance between the conveyor body b and the agricultural products N, which makes it difficult to pick up the agricultural products N smoothly and causes a decrease in harvesting efficiency.

If the lateral width of the crawler of the harvester and the pitch of the recess U do not match, the harvester will be in an inclined state, and the conveyor body b will incline accordingly, so that the interval with the crop N becomes large, and similarly smooth. It becomes difficult to pick up a large crop N.

The present invention was created in order to solve such a problem, and its purpose is to pick up only agricultural products corresponding to the unevenness and inclination of the field, and to enable efficient harvesting, and Each conveyor segment that constitutes the pick-up device provides a durable and robust pick-up device for the harvester.

[0009]

In order to achieve the above-mentioned object, the present invention provides a pick-up device for picking up a crop in a forward direction,
In a harvester equipped with working devices for processing agricultural products in the rear and traveling by crawlers, the conveyor body that picks up the agricultural products and transfers them to the rear is a row of conveyors divided into multiple groups in the forward direction. It is characterized by being arranged in a shape.

Each of the conveyor divisions is characterized in that it is composed of a first-stage conveyor structure and a second-stage conveyor structure, and each of the conveyor divisions is connected via an operating device. It is characterized by being configured to be independently tiltable.

[0011]

According to the present invention, the first stage of each of the conveyor constructions in the plurality of sets of conveyor divisions arranged in a row picks up the agricultural produce in the field, and the next second stage of the conveyor construction is carried out. After moving the agricultural products, the agricultural products are moved to the following working device. At the time of picking up this agricultural product, by providing a separate operating device to each conveyor divided body divided into a plurality of sets, each conveyor divided body can be adjusted in inclination angle in accordance with the ground of the field, Can perform efficient harvesting work.

The pick-up device is composed of a plurality of conveyor divided bodies divided into a plurality of rows in a row with respect to the traveling direction of the harvester, and further divided into a first-stage / second-stage conveyor structure. Therefore, each of the narrow conveyor divisions can independently adjust the inclination angle via the actuator so as to correspond to the ground of the field, so that it does not pick up only the crops and does not pick up the clods. The durability of each constituent member of the lifting device is improved, and the damage can be prevented. The pick-up device is divided into a plurality of sets, and accordingly each conveyor divided body is configured to have a narrow width, so that it is much easier to pick up crops than a wide conveyor body, and it is prevented from being picked up. The efficiency of harvesting work is improved.
