[Detailed description of the device]

[0001]

[Industrial application] The present invention digs and harvests agricultural crops in the field, such as potatoes and onions, and at the same time sorts the digged agricultural crops into a crop storage tank mounted on the machine base by a transportation means. However, it relates to the improvement of the harvesting season of so-called towed-moving potato harvesters and onion harvesters.

[0002]

[Prior art and its problems] Generally, harvesters such as potato harvesters and onion harvesters are used to convey crops such as a digging blade, excavated potatoes and onions to a machine base that is pulled by a tractor. Means, a crop storage tank for storing crops is provided, and the standard size crops selected by the selection conveyor constituting the transportation means are installed on the machine base below the conveyor end of the selection conveyor. While being accommodated in the inside from the end of the conveyor, non-standard agricultural products are accommodated in the waste storage tank installed on the machine base just below the agricultural products in the process of being conveyed on the selection conveyor. . by the way,
Agricultural products that are sorted and stored in the standard product storage tank and the waste storage tank are packed in bags that are set in advance in the tank, and when they are full, they are filled with a crane or the like, and are used as the bed of a large container or truck. However, since the waste storage tank of the conventional harvester is installed on the machine base so that it can be rolled over in the lateral direction of the machine base, if the waste crop is packed in a bag, the tank will be replaced. After the bag was overturned and the bag filled with agricultural products was once thrown to the ground, it could be transferred to the container of a large container or truck by a crane or the like, and the transfer was troublesome.

[0003]

The present invention has been made in view of such conventional circumstances, and the technical problem to be solved is to directly fill a bag full of agricultural products from a storage tank. The purpose is to provide an improved crop harvester that can be lifted by a crane and transferred to a large container or a truck bed.

[0004]

[Means for Achieving the Object] The technical means taken by the present invention to achieve the above object is to install a crop storage tank mounted on the machine base just below the sorting conveyor of the conveying means. It is characterized in that it is installed so as to be slidable in the lateral direction and a part of the work steps located in the sliding direction of the storage tank is openable and closable at tank width intervals.

[0005]

According to the above-mentioned technical means of the present invention, a part of a work step configured to be freely opened and closed is opened so that the crop storage tank is removed from under the sorting conveyor in the lateral direction of the machine base. The crops in the packed tank can be lifted directly above the tank with a crane, taken out of the tank, and transferred to the container of a large container or truck.

The conveyor 3b
A tractor towed type potato harvester or onion harvester equipped with a work step 7 for confirming the transport condition of the agricultural products 6 transported above and for removing the spoiled agricultural products. The storage tank 4 is attached so as to be slidable in the lateral direction of the machine base 1.

The sliding movement mechanism of the waste storage tank 4 includes two rails 10 having a substantially U-shaped cross section and two side frames of the machine base 1.
A frame frame 11 is formed on the machine base 1 which is arranged in parallel with the tank 4 across the space 1a and has a rectangular shape in a plane. The square slide rods 12 are fitted and mounted on both side rails 10 of the frame frame 11. In addition, a hydraulic or air cylinder 16 is fixedly provided between the connecting rod 13 of the slide frame 14 and the rear frame 15 of the gantry frame 11 which is formed by connecting both side slide rods 12 with the connecting rod 13. (See FIG. 2), and the waste storage tank 4 is placed on the slide frame 14.
Is fixedly installed, and the slide frame 14 is slid forward and backward by the cylinder 16, and the scrap storage tank 4 filled with bags 17 filled with agricultural products 6 such as potatoes and onions is sorted and conveyed.
It is designed to be slid to the side of the machine base 1 which is disengaged from below 3b. A part of the work step 7 located in the sliding direction of the waste storage tank 4 is configured to be openable / closable.

The opening / closing mechanism of the work step 7 is located on the side of the waste storage tank 4 and is provided over substantially the entire length of the sorting conveyor 3b. (The central part in the vertical direction) is separated from the step portions 7a on both sides at the width interval of the tank 4 as shown, and the short side edge of the separation step portion 7b is adjacent to the short side edge of the step portion 7a on one side (right side in the drawing). And a hydraulic or air cylinder 19 is fixedly installed from the lower part of the support frame 18 of the step portion 7a to the lower surface of the separation step 7b (see FIG. 1). The separation step is pivoted upward with the pivotal part of the one-sided step 7a as a fulcrum, and the waste storage tank 4 is moved from the space between the stepped parts 7a on both sides to the lateral direction of the machine base 1 which is removed from the bottom of the sorting conveyor 3b. To be able to slide I am doing it.

Thus, according to the harvesting machine of the present embodiment having the above-described structure, the agricultural products 6 excavated by the excavating blade 2 are moved to the upper side of the machine base 1 by the scooping conveyor 3a constituting the conveying means 3. Substandard crops that are picked up and transported, and then transferred from the end of the conveyor to the sorting conveyor 3b and sorted
When 15 is fully stored in the bag 16 in the waste storage tank 4 below (see FIG. 5), the cylinder 19 is operated to move the separation step portion 7b upward as shown by the chain double-dashed line in FIG. Pivot and lift to open the side of the waste storage tank 4 in the sliding direction.
