Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention is a so-called tractor that digs and collects agricultural crops in the field, such as potatoes and onions, and at the same time selects and collects the excavated crops in the crop storage tank mounted on the machine base by the transport means. It concerns the improvement of the harvesting season for crops such as mobile potato harvesters and onion harvesters.

[0002]

[Prior art and its problems]

 In general, harvesters such as potato harvesters and onion harvesters have a tractor-pulled machine base, a digging blade, a transport means for transporting crops such as excavated potatoes and onions, and a crop storage tank for storing the crops. The standard-sized agricultural products selected by the selection conveyor that constitutes the transportation means are stored from the end of the conveyor into the standard product storage tank installed on the machine base below the end of the conveyor of the selection conveyor. On the other hand, non-standard agricultural products are stored in the waste storage tank installed on the machine base just below the agricultural products in the process of being transported on the selection conveyor. By the way, the agricultural products that are sorted and stored in the standard product storage tank and the waste storage tank are packed into bags that are set in advance in the tank and filled up. However, the standard product storage tank or 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 it is packed in a bag, the tank is overturned and the bag filled with the agricultural products is once thrown out on the ground, and then it can be transferred to a large container or the bed of a truck by a crane, etc., which is troublesome. It was

[0003]

[Problems to be solved by the device]

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

[0004]

[Means for achieving the object]

 The technical means taken by the present invention to achieve the above-mentioned object is to make a crop storage tank, which is located just under the sorting conveyor of the transport means, mounted on the machine stand slidable in the lateral direction of the machine stand. It is characterized by being installed.

[0005]

[Action]

 Thus, according to the above-mentioned technical means of the present invention, by slidingly moving the crop storage tank in the lateral direction of the machine stand removed from under the sorting conveyor, the crops in the bagged tank are removed. Lift directly above the tank with a crane, take it out of the tank, and transfer it to the container of a large container or truck.

[0006]

【Example】

 An example of the embodiment of the present invention will be described below with reference to the drawings. The conveyor means 3 comprises a scooping conveyer 3a which is provided in the shape of a digging blade 2 from the rear of the excavating blade 2 toward the upper side of the machine base 1 and a sorting conveyor 3b which is parallel to the machine base 1 from the end of the conveyor. A scraper storage tank 4 is installed directly below the sorting conveyor 3b, and a standard product storage tank 5 is installed below the end of the conveyor, which is a tractor towed type potato harvester or onion harvester. The waste storage tank 4 is slidably mounted in the lateral direction of the machine base 1.

[0007] The sliding movement mechanism of the waste storage tank 4 has a planar rectangular shape in which two rails 8 having a substantially U-shaped cross section are arranged in parallel at both sides of the frame 1a of the machine base 1 at a width interval of the tank 4. The frame frame 9 is attached to the machine base 1, and the square slide rods 10 are fitted and mounted on the rails 8 on both sides of the frame 9 and the slide rods 10 on both sides are connected by the connection rods 11 to form a frame. A hydraulic or air cylinder 14 is fixedly installed between the connecting rod 11 of the slide frame 12 and the rear frame 13 of the gantry frame 9 (see FIG. 2), and the waste storage tank 4 is stopped on the slide frame 12. Installed, and the slide frame 12 is slid forward and backward by the cylinder 14 and the scrap storage tank 4 filled with bags 16 of agricultural products 15 such as potatoes and onions is removed from the bottom of the sorting conveyor 3b. It is designed to slide in the direction.

Thus, according to the harvester of the present embodiment configured as described above, the crop 15 excavated by the excavation blade 2 is moved upwards from the machine base 1 by the scooping conveyor 3a that constitutes the conveying means 3. At the time when the non-standard crops 15 picked up and transported, transferred from the end of the conveyor to the sorting conveyor 3b and sorted, are fully stored in the bag 16 in the waste storage tank 4 directly below (see FIG. 3). ) By operating the cylinder 14 and slidingly moving the slide frame 12, the waste storage tank 4 is moved to the side of the machine base 1 which is removed from under the sorting conveyor 3b, and the bag 16 in which the agricultural products 15 are packed 16 Can be lifted directly above the tank 4 with a crane 17 etc. and taken out of the tank 4 (see Fig. 4), and can be transferred to the bed of a large container or truck.

It should be noted that, in the above-mentioned embodiment, the case where only the waste storage tank 4 for storing the nonstandard agricultural products 15 is slid in the lateral direction of the machine base 1 has been described in detail. Also in the case of the standard product storage tank 5 for storing crops, it is of course free to have a structure in which the same slide mechanism is slid to the side of the machine base 1.

[0010]

[Effect of the device]

 Since the crop harvesting machine of the present invention is constructed as described above, it has the following operational effects. The crop storage tank, which is located directly below the sorting conveyor of the transport means and is mounted on the machine stand, is installed slidably in the lateral direction of the machine stand. By sliding it to the side 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 bed of a large container or truck. Can be done. Therefore, according to the crop harvester of the present invention, the conventional laborious work of throwing a bag filled with crops on the ground and then transferring it to a large container or a truck bed by a crane is eliminated. The transfer work can be performed easily and quickly. Similar to the waste storage tank, the standard product storage tank is slidably installed on the machine base as described in detail in the example, so that bags filled with agricultural products (standard size agricultural products) can be directly packed. Since it can be lifted up and taken out of the tank, in addition to the effects described above, the effect of eliminating the risk of damaging agricultural products can be expected.
