[Means to solve the problem]

This invention was proposed in view of the above problems, and took the following technical measures.

That is, a device 2 for digging up onions, a conveying device 3 for transporting the dug onions upward, and a predetermined number of onions thrown downward from the conveying device 3 are received, and the leaves and stems of the onions are conveyed. In the onion harvesting machine, the onion harvesting machine has a carrier 6 that is held in an upward position and guided to the leaf and stem cutting device 5. The carrier 6 is connected to an endless band 10 and each The element has a box-like shape with an open top, and when it is inverted to a downward position, the leaves are cut by a cutting device 5 located below, with the leaf stem part of the onion inside the box facing downward. The onion harvesting device is characterized in that it is configured to cut the stem.

[Examples and their effects]

Hereinafter, the present invention will be described in detail based on the drawings. First, to explain the configuration, FIG.

This figure shows an overall side view of an onion harvesting device 1 according to the present invention, and this onion harvesting device 1 has a rotation speed of 1.
Power-driven digging device2. A transport device 3 transports the dug onions upward, and a device 4 receives the onions discharged downward from the terminal end of the transport bag [3 and distributes them left and right. The distribution device is located below the device 4, and consists of a conveyor 6 and the like that transports each onion to the cutting section of the cutting device 5. It is towed continuously at the rear. The digging device 2 is driven by a chino and sprocket mechanism, and is rotated in the direction of arrow A in FIG. 1 to transport the dug onions upward.

The conveying device 3 connected to the rear thereof is provided obliquely so that its upper end is tilted backward when viewed from the side, and is rotated in the direction of arrow B in the figure by a drive mechanism described later. Configure it as follows. The conveyance device 3 consists of a rod 8 which is approximately U-shaped in plan view and is passed between the left and right chains.
Place the onion on this rod 8 and lift it upward.

The distribution device 4, which is provided facing the end of the transfer of the conveyance device 3, consists of a plurality of rollers 9..., and the rollers 9.9 are arranged in two stages, upper and lower, with appropriate intervals left and right in the horizontal direction. It is rotatably provided around the axis in the front-rear direction.

Therefore, the onion thrown downward from the rear end side of the conveying device 3 is not guided in contact with the left and right adjacent rollers 9 and 9 groups, but is dropped into the gap between the left and right rollers 9, 9, and is dropped in the lateral direction. It is transferred to the carrier 6 without moving.

The conveyor 6 provided below the device 4 has an endless chino 10 as its transport section, and only the upper surface of the chino 10 has an upper surface.

An open box 11 is fixedly provided in a continuous manner in the transport direction. As shown in FIG. 2, the box 11 of this conveyor 6 is provided so as to pass between each roller 9 when viewed from a plan view.

(In this example, the configuration is shown for digging up onions planted in four rows.) 12... are the clamping rails for the onion leaf stems provided close to the left and right sides of this box 11. The box 11 of the transport body 6, which is made up of a horizontal part 12a and vertical parts 12b, 12b, is long in the front-rear direction along the top of the box 11, and its terminal end is as shown in FIG. The sprocket 10 of the conveyor 6 is wound around the bottom of the sprocket 13 on the rear side. Further, the vertical height of the vertical portion 12b at the starting end of the holding rail 12 is formed to be lower than the intermediate portion in the front-rear direction, and the interval between the adjacent horizontal portions 12a, 12a when viewed from a plane is smaller than the intermediate portion. It is also designed to be wider. That is, as shown in FIG. 4, the onion receiving parts are widely spaced, so the spherical part of the onion enters the box, and as it is transferred to the rear, the space narrows, and the leaves and stems fill the space. Configure it so that only the currency can be used as currency.

When the onion is transferred rearward in this state, the box 11 that has gone around the outer periphery of the rear sprocket 13 is eventually reversed, and the onion is also reversed so that the leaf and stem portions are facing downward. A guide body 14 having a chevron-shaped cross section is extended in the front and back direction facing the terminal end of the clamping rail 12, and the left and right guide bodies 14
There is a gap between them that allows only the leaves and stems to pass through.

A cutting device 5 having a rotary blade 15 is provided below the guide body 14, and a conveyor 16 is provided at the front of the guide body 14 to send the onions whose leaves and stems have been cut outward in the left and right lateral directions. It is configured to be collected in a container 17 supported by a frame 7.

Next, the drive system of this device 1 will be explained based on the power transmission diagram shown in FIG.

Reference numeral 18 denotes a bevel gear box attached to the front part of the frame 7, on which an input shaft 19 is mounted facing forward, and a pulley 21 is fixed to a shaft 20 taken out laterally.

Two shafts 23 and 24 are mounted laterally on a reduction gear case 22 installed at the lower part of the frame 7, and a two-stage pulley 25 is attached to the shaft 23, and a sprocket 26 is attached to the shaft 24.

27 is a belt wound between pulleys 21 and 25, 2
Reference numerals 8 and 29 denote a top shaft and an undershaft of the conveying device 3, and two sprockets 30 and 31 are fixed to one side of the top shaft 28, and a sprocket 32 is attached to the opposite side. A chino 34 is hooked and rotated between the sprocket 33 attached to the undershaft 29 and the sprocket 32 of the top shaft 28, and the sprocket 35 fixed to the outer end of the undershaft 29 and the top of the digging device 2 are connected. A chino 38 is hooked between the sprocket 37 attached to the outer end of the shaft 36 and rotated. 39 is a drive shaft for driving the conveyor 6, and two sprockets 40 are provided at the end of the drive shaft.
．． 41, and sprocket 30 and sprocket 40.
The configuration is such that power from the transport device 3 side is transmitted to the transport body 6 side by a chino 42 interposed therebetween.

In the figure, reference numeral 43 is a cheno, and 44 is the above-mentioned kon.

On the upper side, when the onion harvesting device 1 is connected to a tractor and towed and the machine moves forward while driving each rotating part, the chain of the digging device 2 and the chain 34 of the conveying device 3 are connected to the first
It rotates in the directions of arrows A and H in the figure, thereby lifting the dug onions upward one by one.

Then, when the onions are dropped downward from the transfer end of the transfer device 3, the onions falling continuously with the heavy spherical part downward are distributed and distributed as appropriate while contacting the rollers 9 of 4. They are distributed laterally and passed between each roller 9.9 and are deposited one by one in the box 11 of the conveyor 6.

When the onion is sent rearward in this state, the leaves and stems that are tilted or turned sideways are all arranged into a substantially vertical shape as they pass through the gaps between the clamping rails 12, and are transferred to the cutting side. FIG. 5 shows the inverted state of onions at the terminal end of the clamping rail 12. The onions sent between the left and right guide bodies 14, 14 in the inverted state are sequentially moved by the onions that are subsequently sent. The onion is pushed forward, and during this time, the blade 15 rotating below cuts the leaves and stems into a predetermined length, and the onions with the leaves and stems cut off are dropped onto the conveyor 16 and placed in the container 17. will be collected.

〔Effect of the invention〕

Since this invention is configured as described above, it has the following technical effects. That is, the dug onion is lifted upward by the conveyor 3 and then released downward to the conveyor 6.
When the onion is dropped onto the box 11, it is placed in the box 11 with the heavy spherical part facing downward, making it easy to separate the leaf and stem part from the bulb part. Since the blade 15 of the rotating cutting device 5 cuts the cut portion, the cutting errors do not occur frequently as in the conventional method, and the harvesting operation can be carried out very efficiently.
