Description

[Detailed description of the invention] (Field of industrial application) This invention is an onion digging method that can dig out the roots of onions that are planted in a ridge without damaging their roots, which are buried in the ground after cutting off the stems and leaves. Regarding machines.

(Prior Art) Onions planted in rows are generally harvested when their stems and leaves have withered and are hanging down on the surface of the rows. For this reason, conventionally, the stems and leaves hanging down on the surface of the ridges were scraped upward and cut to a predetermined length, and then the onions were dug out from the ridges.

(Problem to be solved by the invention) By the way, some of the onions planted in the ridges hang down on both sides of the ridges when their stems and leaves wither. Therefore, in the case of such onions, the conventional apparatus has the disadvantage that the stems and leaves are dug up without being cut to a predetermined length. For this reason, the stems and leaves of onions dug out in this way had to be cut to a predetermined length by hand, which caused a problem of extremely low work efficiency during harvesting.

Therefore, the present invention eliminates the above-mentioned drawbacks and ensures that the onion leaves are kept at the specified length during harvesting, even if the onion leaves are hanging down on both sides of the ridge. The purpose of the present invention is to provide an onion harvesting machine capable of cutting onions with a straight blade.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a pair of scraping rotors having radial claws on the lower left and right sides of the front of the chassis on which the engine is mounted. The toes protrude toward the inside of the chassis, and the rotating shaft of the scraping rotor is connected to the engine so as to rotate in the opposite direction to the drive wheels. A plurality of inclined guide frames are installed, and a hammer cutter is horizontally mounted above these guide frames.Furthermore, a pair of vibrating frames are installed on the left and right rear of the chassis, which are vibrated back and forth about the upper support by the engine. are hung down, and both ends of horizontal hori-dori blades are fixed to the lower ends of these.

(Function) In other words, the present invention scrapes up the onion leaves hanging down on both sides of the ridge and scrapes them upwards with a rotor, and at the same time cuts them off with a hammer cutter, and places the cut off onion leaves on the ground. It was designed to be excavated from the inside.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic side view of an embodiment of the present invention.

In the figure, reference numeral 1 denotes a vehicle chassis, on which an engine 2 is mounted and, for example, various elements described later are arranged. 3 is a hammer cutter provided at the front lower part of the chassis 1, and has cutting blades 3a radially around the outer periphery of a horizontal shaft 3b installed on the chassis 1. This cutting blade 3a
As shown in FIG. 2, the two blades are swingably attached to the horizontal shaft 3b with bolts and nuts, and when the hammer cutter 3 is rotated, it stands upright with respect to the horizontal shaft 3b due to centrifugal force. Also, the horizontal shaft 3 of this hammer cutter 3
b is rotated in a predetermined direction from the output shaft 2a of the engine 2 via a plurality of belts.

Reference numeral 4 denotes drive wheels attached to the left and right sides of the chassis 1 so as to rotate at a reduced speed from the output shaft 2a of the engine 2 via a belt.The drive wheels 4 move forward while supporting the chassis 1 across the ridges 7.

Reference numeral 5 designates a plurality of guide frames arranged below the hammer cutter 3, which lift up the onion stems and leaves as the present embodiment moves forward, and whose base ends are fixed to the chassis 1 so that the mounting position can be adjusted to be long or short. At the same time, the tip is formed sharply.

Reference numeral 6 denotes a pair of scraping rotors having radial pawls 6a provided on the lower left and right sides of the front of the vehicle chassis 1. This scraping rotor 6 has its toe protruding toward the inside of the chassis 1, and its rotation axis is connected to the drive wheel 4.
It is connected to the output shaft 2a of the engine 2 via a belt so as to rotate in the opposite direction.

For example, six claws 6a of the raking rotor 6 are provided radially as shown in the figure, and each of the radial claws 6a is curved toward the center, so that it is easy to scrape up stems and leaves hanging down on the sides of the ridges 7. Do it like this.

8 straddles the ridge in the same way as the drive wheel 4, and
These are a pair of front wheels that guide the chassis 1 and are fixed to the front part of the chassis 1. This front wheel 8 can be moved up and down by adjusting the adjuster 9 and the set screw 10, and the depth of penetration of the guide frame 5 into the ground and the approach of the hammer cutter 3 to the ground surface are adjusted according to the height of the ridge 7. Adjust.

Reference numeral 11 designates a pair of vibrating frames whose upper ends are vertically disposed on the rear left and right sides of the chassis 1 so as to be swingable back and forth.

Reference numeral 12 denotes a cutting blade that is installed approximately horizontally at the lower ends of the left and right vibrating frames 11, and as shown in the plan view of FIG. It consists of a book soil shaking frame 12b. The soil shaking frame 12b may be configured to gradually slope upward toward the rear. Then, a plurality of soil shaking frames 12c are provided slightly higher on both sides of the soil shaking frame 12b to prevent the roots of the onions to be dug from spilling out from both sides of the digging blade 12.

Further, the left and right ends of the blade body 12a are vertically extended upward, and the extended portion 12d is fixed to the vibrating frame 11 with bolts and nuts. Furthermore, the extension part 1
A cutting edge for earth cutting is formed on the front edge of 2d, as shown in the cross section of FIG. The extension portion 12d of the digging blade 12 is provided with a plurality of holes that engage with a plurality of holes provided in the vibrating frame 11. Therefore, by changing the position of this hole, the depth of penetration of the digging blade 12 into the ground can be adjusted according to the height of the ridge 7.

Reference numeral 13 denotes left and right eccentric wheels that are interlocked with the output shaft 2a of the engine 2, and the vibration frame 11 is pivotally attached to the rear end of a continuous frame 14 connected to these eccentric wheels, causing the vibration frame 11 to violently vibrate back and forth. 14a is an operating handle.

In such a configuration, when the chassis 1 moves forward by the rotation of the driving wheels 4 and the front wheels 8 that straddle the ridge 7, the pair of raking rotors 6 that extend on both sides of the ridge 7 first turn and cover both sides of the ridge 7. Rake up the onion leaves that are hanging down on the surface. In parallel with this, the onion stems and leaves hanging down on the upper surface of the ridge 7 are also squeezed upward by the guide frame 5.

Next, as shown in FIG. 2, the cutting blade 3a of the hammer cutter 3 installed at the front lower part of the chassis 1 rotates, and the scraping rotor 6 and the guide frame 5 are rotated as described above.
Cut off the unnecessary stems and leaves of the onion that have been raked upward by the scraper.

Furthermore, the digging blade 12 fixed to the vibrating frame 11 cuts off the ridges 7 while vibrating back and forth, and the roots of the onions remaining in the ground are removed from the soil shaking frame 1 by the blade 12a.
Excavate on top of 2b and 12c, shake off the soil and release it to the ground surface.

(Effects of the invention) As explained above, according to the invention, the onion stems and leaves hanging down on both sides of the ridge are scraped upward, the picked-up stems and leaves are cut to a predetermined length, and then Since the roots are released to the ground surface, even if the onion has stems and leaves that hang down on both sides of the ridge, the roots can be released to the ground surface by cutting off the stems and leaves at a predetermined length. Harvesting operations become extremely efficient and easy.
