Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vegetable harvesting machine, particularly for harvesting cabbage, lettuce, and Chinese cabbage.

[Prior art]

Conventionally, harvesting machines for harvesting cabbage, lettuce, and Chinese cabbage are technically extremely difficult and there are few precedents.

The one currently under development has a configuration in which vegetables are harvested from the field using a reaping device installed in the MIF section of the aircraft, are conveyed onto the aircraft by a conveyor, and are automatically dropped and stored in the NLA box at the rear. are known.

However, according to this configuration, vegetables can be transported during the transportation process and f!
4. When vegetables are dropped into boxes and packed, they are often damaged, reducing the quality of the vegetable product and causing spoilage.

[Problem that the invention seeks to solve]

The present invention relates to an improvement on the conventional type described above, and aims to realize a harvesting machine that can collect vegetables such as cabbage without damaging them, and can be moved while holding the harvesting machine on its side. It is something to do.

The second invention is a method for classifying and sorting boxes into a plurality of storage boxes mounted on the aircraft to form boxes ff+7, and the third invention is a sorting method for loading and transporting harvested vegetables. A conveyor is installed, and one worker sorts the crops by class and stores them in storage boxes placed in the field.

[Means for resolving conflicts]

This invention uses the following technical means to achieve the above object.

First, the invention of the first month is that a moving machine body 1 is provided with a placing section 2 for placing harvested vegetables Id2, and a passing section that can hold the harvested vegetables in a holding state near the placing section 2. A harvesting device 6 consisting of a cutting portion 4 and a holding portion 5 is provided below the passage portion 3, and the vegetables harvested by the harvesting device 6 are placed by the holding portion 5 through the passage portion 3. This is a vegetable harvesting machine that can be transported up to part 2.

In the second invention, the moving machine body 1 is provided with a placing section 2 on which the harvested vegetables are placed, and a passing section 3 is formed near the placing section 2 to be able to lift the harvested vegetables while holding them. A harvesting device 6 consisting of a cutting section 4 and a holding section 5 is provided below the passage section 3, and the vegetables harvested by the harvesting device 6 can be transported by the holding section 5 through the passage section 3 to the placing section 2. In the configuration, a cradle 46 on which a plurality of storage boxes 45 for storing harvested vegetables can be placed is provided at the rear of the aircraft body 1.
This is a vegetable harvesting machine equipped with a

Next, the third invention provides a mounting section 2 for placing harvested vegetables on the moving machine 1, and a passage section near the mounting section 2 that can carry the harvested vegetables while holding them. form 3,
A harvesting device 6 consisting of a cutting portion 4 and a holding portion 5 is provided below the passage portion 3, and the vegetables harvested by the harvesting device 6 can be transported by the holding portion 5 to the placing portion 2 via the passage portion 3. This vegetable harvesting machine is equipped with a sorting conveyor 47 on which harvested vegetables can be placed and conveyed.

[action, effect]

First, Ijfl starts harvesting cabbage while driving each rotating part of the machine.

Aircraft 1 is moving vehicle 1 while straddling a row of vegetable planting rows.
117 into the groove and drive it to run.

At this time, the front steering shaft 7' is rotated by the wheel 7' due to the relationship between the worm wheel 8 and the worm 9 provided in the middle of the operating mechanism.
It is locked so that it does not move when a direction change is transmitted from the side.

In this way, when the machine 1 reaches the second position of the cabbage planting row, the flat image sensor 1o detects the boundary between the edible bulb and the outer leaf of the cabbage from above, and The waiting harvesting device 6 begins to descend.

At this time, the pair of left and right holding arms 11, 11' individually move the distance between them according to the size of the edible spherical portion of the cabbage based on the detection by the planar image sensor 10, and enter the holding position.

Further, the outer leaf removal belt 12 starts rotating along with the downward movement.

Next, the harvesting device 6 descends until the image sensor 13 attached to its bottom detects the desired cabbage, and the harvesting height is determined.

As described above, when the harvesting device 6 reaches the back of the cabbage to be harvested, the pair of holding arms 11 and 11' hold the cabbage, and the forward motion of the machine body 1 is applied to push the cabbage forward. The cutting section 4 rotates to perform cutting.

Next, the holding arms 11 and 11' start to ascend while holding the cabbage from the left and right sides, and after passing through the passage section 3, are reversed and continue ascending, and are placed on the mounting section 2 with the cut stem section on the "-" side. reach

The cabbage is then placed on the placing part 2 consisting of the conveyor 14 with the holding arms 11,11' opened.

In the second invention, an operator visually sorts the cabbages conveyed by the conveyor 14 by class and manually packs them into the corresponding storage box 45 on the pedestal 46.1-.

In this way, the harvested cabbages are sorted according to class and packed in each storage box 45.

Next, the invention No. 3 "1" is to visually sort and separate the cabbage transferred from the conveyor 14 to the sorting conveyor 47 and pack it into a storage box 45 placed on the ground.

In this configuration, the sorting conveyor 47 is driven by the drive motor 4
8 allows cabbage to be sorted by moving it appropriately.

As stated above, this invention enables cabbages to be transported and packed without damaging them during a series of harvesting operations from picking them in the field to packing them into boxes, thereby improving the quality of the product. It is possible to create a vegetable harvesting machine that causes very little damage.

〔Example〕

The harvesting frame 37 is located below the guide shaft 31 and attached to the lower part of the moving box 27, and is provided with an outer leaf separation device 38 on the bottom surface and a cutting blade device 39 above it.

In the embodiment, the outer leaf separating device 38 separates the belt 12 from the harvesting frame 3.
7 and is driven by a motor 41 to forcibly guide the outer leaves of the cabbage to the rear.

Note that a roller may be used instead of the bell 1-12.

The cutting section 4 is rotated by a motor 42 and is configured to be able to cut the stem of the cabbage.

The loading section 2 is provided with a belt conveyor 14 whose starting end faces the passing section 3 and whose terminal end extends to the rear of the machine body 1, and the cabbages placed on it from the holding arms 11 and 11' are transferred to the machine body. It is configured so that it can be transported backwards.

44 indicates a conveyor sensor, which is connected to the belt conveyor 1.
The configuration is such that the presence or absence of cabbage can be detected at the terminal portion of the line 4.
