Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an onion preparation machine, and specifically relates to a preparation machine that efficiently cuts onion leaves dug up from a field. .

<Prior art> If onions dug from the field are left with leaves attached when drying, the weight and quality of the onions will drop significantly as the leaves consume nutrients during the drying process. Conventionally, onion leaves planted in the field are cut with scissors, etc., and then dug up with a suitable excavator, or the onion leaves that have been dug up are cut with scissors, etc. was going on.

(Problem to be solved by the invention) However, when the leaves are cut off manually as in any of the cases, it is practically impossible to cut off the leaves during the limited harvest period by just using normal labor. This was technically impossible, and furthermore, some sort of change was ``desired'' from the standpoint of distributing labor and increasing production efficiency.

In addition, in order to avoid such a situation, by rotating a pair of left and right screws provided with spiral protrusions on the outer peripheral surface mutually inwardly, the onions are conveyed by the conveying action of the protrusions, and the protrusions are There is also a method that uses the downward combing action of the onion to tear off the leaves of the onion, but in this case, the main part of the onion is pulled out along with the leaves, resulting in a decrease in quality.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide an onion preparation machine that can efficiently cut onion leaves dug up from a field.

<Means for Solving the Problems> The present invention provides a discharge chute at the rear of a hopper into which onions dug up from a field are fed into the front end, and a pair of left and right screws that are driven to rotate inwardly. A plurality of sets of screw conveyors arranged adjacent to each other are arranged on the bottom surface of the hopper.

Further, the spiral protrusion of the screw is constructed by planting resin fibers, and a pair of left and right Vs rotate in a substantially vertical plane.
A belt conveyor is disposed between each of the screw conveyors and the discharge chute. Then, a disc cutter pivotally supported between one of the pair of V-belts and a cylindrical receiver pivotally supported between the other V-belt are brought into rotational contact approximately at the center between the V-belts. The configuration is such that it is maintained.

Action> While the onions put in the hopper are transported by the transport action of the screw conveyor, they are transported backwards by the transport action of the spiral protrusions formed on the outer circumferential surface of the screw conveyor, and the onions are conveyed backward by the combing action of the protrusions. Arrange the onions in the following order:

While the onion, which is held in a predetermined inverted state, is conveyed toward the discharge chute by a belt conveyor using a V-belt, the leaves hanging down from the main body of the onion are removed from the disk car 7.
I try to cut it off with a tap.

<Example> Fig. 1 is an overall schematic side view showing an embodiment of an onion harvesting machine equipped with a preparation machine according to the present invention, and Fig. 2 is a schematic plan view of the same. A control handle 4 and a control seat 5 are attached to the front end portion of a running vehicle body 3 equipped with a control handle 4 and a control seat 5.

Further, a scraper 6 tilted forward and downward is attached to the front f portion of the traveling heavy body 3 so as to be adjustable up and down via a bracket (not shown), and the rear end of this scraper 6 and the lower end of the lifting conveyor 7 are connected. It is connected via an upper semi-conveyor 8. In addition, the earthen conveyor 8 has a driving wheel 8a and a driven wheel 8.
It is constructed by connecting the ends of rods 8C18C along the left and right direction to a pair of left and right chees 7 wound between them at a predetermined pitch. While foreign matter is dropped from between the b-rads 8c, 8c, only the onions are transported to the transfer start end of the lifting conveyor 7, which will be described later. Further, this soil separation conveyor 8 is adjusted to swing in a downward direction as the scraper 6 moves up and down using its rear end as a fulcrum.

The lifting conveyor 7 has the function of lifting and transporting the onions received from the soil separation conveyor 8 rearward and upward, and removing soil, stones, etc. mixed in the onions. The ends of rods 7b, 7b having comb-shaped protrusions 7a, 7a arranged in parallel at intervals of Scoop it up and transport it.

Further, a shallow box-shaped hopper (not shown) is provided below the rear end of the lifting conveyor 7, and a plurality of sets of screw conveyors 9 are provided along the front-rear direction at the bottom of this hopper. ing. This screw conveyor 9 is composed of a pair of left and right hollow screws 9d and 9a that are rotationally driven inward during phase 1, and have resin m! Plant i (
The helical protrusions 9b, 9b are formed by fixing with adhesive.

9c, 9c is a gear that interlocks the left and right screws 9.9; 9d is a drive shaft; 9e is a reversing guide that contacts and reverses the onions conveyed by the screw conveyor 9; the drive shaft 9d is not shown; It is linked to the drive mechanism.

Furthermore, the rear end of the traveling vehicle body 3 is comprised of a first chute lOa that is inclined toward one side of the vehicle body, and a second chute 10b that is tiltable toward either side of the vehicle body. In addition to providing a discharge chute IO, this discharge shoe) 10
and the rear end of the screw conveyor 9 are connected via a belt conveyor 11 formed by a pair of left and right V-belts lla and llb.

Then, a cylindrical receiver 12a disposed between one V-belt lla and a disc cutter 12b disposed between the other V-belt llb are held in rolling contact between the V-belts lla and 11b. The cutting device 12 is configured to cut the onion leaves being conveyed by the belt conveyor 1z by rotationally driving the cutting device 12 by a driving means (not shown).

Note that when both the shoes 10a and 10b are tilted in the same direction as shown by the solid line in FIG. Although it is released to the side.

When the second shoe job is tilted in the opposite direction as shown by the dashed line in the figure, onions are released into the center of the vehicle body. 13 is an auxiliary sheet arranged in front of the lifting conveyor 7.

In the above configuration, when the height of the scraper 6 is adjusted using an adjustment handle (not shown) and the traveling vehicle body 3 is moved forward while rotating each part, the roots of the onion planted in the field are cut by the scraper 6. .

The onions dug up by the scraper 6 are pushed by the onions that were first dug out, move backward on the upper surface of the scraper 6, and are supplied to the upper separation conveyor 8. Then, while being conveyed rearward by the upper separation conveyor 8, dirt, stones, etc. adhering to or mixed with the onions are separated.

Further, the onions conveyed to the rear end of the upper separation conveyor 8 are gradually conveyed upward by the scooping action of the projections 7a, 7a of the lifting conveyor 7, and are then dropped and supplied to the front end of a hopper (not shown). Incidentally, this is because the foreign matter is removed by a worker sitting on the auxiliary seat 13 during the lifting and conveying by the lifting conveyor 7.

Only onions will be supplied to the hopper.

The onions put into the hopper are transported by a screw conveyor 9, and spiral protrusions 3a, 9 are formed on the outer circumferential surface of the onion.
They are arranged in an inverted state under the combing action of a (
(See FIG. 4), if the reversing guide 9e is provided above the screw conveyor 9 as in the embodiment, the onion will definitely be reversed by contact with this guide 9e, so the length of the screw conveyor 9 will be increased and the conveying pressure ffI ) can be shortened.

Furthermore, the onions that have been conveyed to the rear end of the screw conveyor 9 as described above are transferred to the belt conveyor 11 as they are and conveyed backwards as shown in FIG. Since the cutting device 12 acts on the way, the leaves are cut off. In addition, the cut leaves remain as they are! II
The onions fall onto the discharge chute IO from the discharge conveyor 11, and are discharged to a predetermined position by the guiding action of the chute IO. For this reason, onions with their leaves cut off are left in an orderly manner in the field where the harvester passes.

In the embodiment, onion leaves dug from a field can be automatically cut by assembling the preparation machine of the present invention into an onion harvesting machine, but the preparation machine of the present invention is configured as a stationary preparation machine. Alternatively, onions that have been dug up by other means may be placed in the hopper and their leaves may be cut off. or,
In the embodiment, the onion discharge position can be changed by adjusting the angle of the discharge chute, but the present invention is not necessarily limited to the embodiment.

<Effects of the Invention> According to the present invention, when onions dug up from the field are put into the front end of the hopper, the onions are turned upside down by the conveying and alignment action of the plurality of sets of screw conveyors disposed at the bottom of the hopper. Since the leaves are arranged in a row and then fed to a cutting device to dynamically cut off the leaves, the leaves can be efficiently cut off without manual work as in the past.

In addition, since the leaves are cut off while the onion is held upside down, the cut leaves will not fall onto the onion. Since the structure is such that the leaves are cut off, there is no need to apply excessive force to the main body of the onion when the leaves are cut off, and it is possible to avoid deterioration in quality caused by cutting off the leaves. Furthermore, since the spiral protrusions of the screw conveyor are made of resin am, the onions will not be damaged due to their engagement with the protrusions, and even if the preparation work is made more efficient with a machine, the quality of the onions will deteriorate. There's no fear.
