Description

[Detailed Description of the Invention] Industrial Application Field of the Invention The present invention is for harvesting and harvesting agricultural crops in the field, especially potatoes and onions, and at the same time packing the crops into containers such as bags and containers. Regarding improvements such as.

Problems of conventional technology Conventional potato harvesters and onion harvesters consist of a tractor-pulled machine base, a transportation means for transporting crops such as a digging blade, excavated potatoes, onions, and a foliar treatment means, and a tank for storing crops. The standard product (product) of the size selected by the selection conveyor that constitutes the transportation means is stored in the tank installed on the machine base.

Then, the agricultural products stored in the tank are opened on the door with the discharge device forming the side of the tank and transferred to a large container installed on the ground, transferred to the truck bed, or at the end of the door. Auxiliary tools are attached, bags are set and packed (about 600 kg per bag).

However, in any case, the harvester having the above-described structure is stored in the tank once, and then it is packed in a container or bag, so that the crops are transferred each time, and the crops are easily damaged. It has a problem such as.

As a modification of such a conventional technique, a harvester for agricultural crops, which is provided with a digging blade, a transportation means for harvested products, and a foliage processing means on a machine frame towed by a tractor, is located in front of a selection conveyor of the transportation means. There has been proposed a harvester for agricultural products in which a turntable is mounted on a stand and a crane is installed around the turntable (see, for example, Japanese Utility Model Publication No. 61-40831).

According to the prior art described in this publication, the container packing work of agricultural products can be performed on the machine after selection, the number of transfers that damage the agricultural products can be reduced, and the packed agricultural products can be easily transported. It has advantages such as that.

However, when packing agricultural products in containers, the containers are kept stationary below the carry-out end of the sorting conveyor, so that the central parts of the containers are high and the peripheral parts are low, so-called piles. When the piled agricultural products are transported, the agricultural products in the mountainous regions often fall into the surrounding areas and are damaged, and it is necessary to break the mountainous products and flatten them before transporting.

In addition, there is known a harvester for crops configured to work by reciprocating the container in a horizontal plane when packing harvested crops from a sorting conveyor (for example, Japanese Utility Model Publication No. 61-66424). Gazette, Japanese Utility Model Publication No. Sho 55-169134, etc.).

According to these two conventional techniques, although the agricultural products piled up in the container may be flattened by the reciprocating motion of the container, the height position of the container cannot be adjusted, and hence the drop between the sorting conveyor and the container is not possible. It could not be adjusted and often caused damage such as bruises to the crops when they were packaged.

The present invention has been made in view of such circumstances, and in addition to the above-mentioned advantages of all the above-mentioned conventional techniques, there is little concern that the crops will be damaged, and it is possible to perform the packing work of the crops. The purpose is to provide a harvester for crops.

Means for Solving Problems The means of the present invention for achieving the above-mentioned object are
In claim (1), the container for agricultural products is provided on the distribution conveyor side so as to be tiltable, and in claim (2), the container for agricultural products reciprocates in a direction orthogonal to the distribution conveyor. This means that it is freely installed and can be tilted freely on the distribution conveyor side.

Action If the harvested agricultural products are packaged while the container for agricultural products is reciprocated and tilted at the same time, the agricultural products are packaged without becoming a single load and not piled up. Then, if the container for agricultural products is tilted, the drop with the distribution conveyor is adjusted and damage to the agricultural products is prevented.

EXAMPLE An example of the illustrated pick-up type potato harvester will be described, and claims (1) and (2) will be collectively described.

The excavating blade 3 is attached in a downward slope toward the advancing direction in a portion of the working machine 1 near the lower advancing direction of the machine frame 2, and a conveying means 7 for harvested crops is provided behind the excavating blade. .

The transport means 7 for agricultural products is composed of a transport conveyor 7-1, which is arranged on the lower side of the machine frame 2 so as to incline upward from the rear of the digging blade 3 toward the side opposite to the traveling direction, and a rotary bucket conveyor 7-2. The carrying-out end of the transfer conveyor 7-1 is arranged in the lower part of the rotary bucket conveyor 7-2, and the harvested crops are configured to drop and transfer to the rotary bucket conveyor 7-2, and the upper part of the bucket conveyor is moved upward. It is configured that the above-mentioned agricultural products conveyed to are transferred to the selection conveyor 4. The sorting conveyor 4 is a rotary bucket conveyor 7-2.
It is a well-known configuration for a conveyor that selectively discharges non-standard agricultural products from the agricultural products transported in step 1. The non-standard agricultural products are discharged into the waste tank 8 and the standard agricultural products are transferred to the distribution conveyor 5. The distribution conveyor 5 is a conveyor for packing standard agricultural products among the harvested agricultural products into two containers 6 while packing them, and is arranged right below the delivery end of the selection conveyor 4 so as to be orthogonal to the selection conveyor 4. . The distribution conveyor 5 is connected to a well-known forward / reverse rotation motor (not shown) installed on the conveyor frame 5-1, and is configured to be forward / reverse rotation. By this forward / reverse rotation, the agricultural products can be distributed to the two containers 6, The conveyor frame 5-1 is connected to the conveyor frame of the selection conveyor 4, and the distribution conveyor 5 is arranged immediately below the unloading end of the selection conveyor 4 by the connection of these conveyor frames. Therefore, the arrangement direction of the sorting conveyor 5 with respect to the selection conveyor 4 can be set to the orthogonal direction when the crane 9 is provided as in the illustrated example, but can be set to the parallel direction when the crane 9 is not provided. Container 6 for crops
Shows a small container as an example, and can be raised and lowered one by one on the left and right sides of the machine frame 2 and can be reciprocated in the direction orthogonal to the distribution conveyor 5 and tilted toward the distribution conveyor 5 side. Arrange freely. Reciprocating means for container 6
Reference numeral 10 denotes an expandable hydraulic mechanism 10 provided in the frame of the tilting frame body 11-1 provided on the machine frame 2 in a direction orthogonal to the distribution conveyor 5 (in other words, a direction parallel to the selection conveyor 4). -1 and the hydraulic mechanism 10 installed in the tilting frame 11-1.
-1 and a reciprocating frame body 10-2 to which one end is connected. The hydraulic mechanism 10-1 of the reciprocating means 10 has one end attached to the inner surface of one side of the tilting frame body 11-1 and the other end attached to the bottom of the reciprocating frame body 10-2 to expand and contract. By doing so, the reciprocating frame 10-2 can be pushed and pulled to reciprocate.
The reciprocating frame body 10-2 of the reciprocating means 10 has a plurality of wheels 10-3 (for example, about four) for smoothly performing the reciprocating motion, and the wheels are provided on the tilting frame body 11-1. Place it on the bottom frame rod. Therefore, the reciprocating means 10 of the container 6 is arranged in a direction orthogonal to the distribution conveyor 5 so that the container 6 reciprocates in a direction perpendicular to the distribution conveyor 5. Constitute. The tilting means 11 for tilting the container 6 to the distribution conveyor 5 side includes a tilting frame body 11-1 in which one side of the distribution conveyor 5 side is hinged on the machine frame 2 and a lower side of the machine frame 2. And an expandable hydraulic mechanism 11-2 having one end attached to the other side of the tilting frame 11-1 (one side opposite to the sorting conveyor side). The tilting frame body 11-1 of the tilting means 11 is wider and longer than the reciprocating frame body 10-2, and is configured so that the reciprocating frame body can be reciprocally mounted.
One longitudinal side of the sorting conveyor 5 is hinged on the machine frame 2. The hydraulic mechanism 11-2 of the tilting means 11 has one end attached to the lower side of the machine frame 2 and the other end attached to the lower surface of the tilting frame body 11-1 on the other side of the longitudinal direction to expand and contract, The lengthwise and other sides of the tilting frame 11-1 are pushed or pulled to tilt the sorting conveyor 5 about the hinged portion.

As described above, since the reciprocating means 10 and the tilting means 11 for the container 6 are separately configured, it is possible to operate them simultaneously or at different times.

The empty container 6 or the container 6 containing standard agricultural products is lifted and lowered by the crane 9 with the crane 9 or without the crane.

Effect of the Invention Since the present invention is configured as described above, it has the following effects.

1. By packing the harvested crops into containers while simultaneously performing the reciprocating movement of the crops containers in the direction orthogonal to the sorting conveyor and the tilting movement to the sorting conveyor side at the same time, there is little concern that the crops will be loaded as a single item It is packed in a container with little concern about being damaged. Therefore, the harvested agricultural products can be packed almost flat in the container, and the flattening work need not be performed prior to transportation.

2. By tilting the container for agricultural products to the distribution conveyor side, the drop between the container and the conveyor can be adjusted, and damage to the agricultural products can be prevented to some extent. Therefore, the harvested agricultural products can be packaged in a container with little fear of damaging them.
