Description

[Detailed Description of the Invention] [Industrial field of application] According to the present invention, the stems and leaves of subterranean crops such as potatoes planted along ridges can be extracted by leaving the roots in the ridges. The present invention relates to a guide rod for dropping a root of a foliage processing machine.

[Prior art]

A conventional foliar treatment machine is provided on opposite sides of a pair with a space therebetween, is inclined rearward and upward, and has a pair of guide bodies on both sides that are narrowed toward the rear as the distance between the opposite guide bodies is reduced. A pair of endless conveyor bodies, which are connected to the rear part of the guide body and are opposed to each other on opposite sides, and the opposite side edges rotate backward and upward, and are located below the front part of the pair of endless conveyor bodies. Then, a pair of earth retaining members arranged oppositely on both sides were mounted on the front portion of the machine frame in which the wheels were mounted on the rear portion (for example, Japanese Patent Publication No. 59-39084).

[Problems to be solved by the device]

According to such a foliage processing machine, the foliage portion above the ridge is raised by the pair of guide bodies, and the ground on both sides thereof is held between the pair of endless conveyor bodies in a state where the ground is held down by the pair of soil holding bodies. Narrowly inserted, it will be pulled out while being transferred upwards with the circulation of the endless conveyor body, but when the ridge surface is covered with a multi-film, it slides on this multi-film. There are problems that the soil retainer catches the mulch film, and that the root also rises up when the foliage is pulled out, and the soil retainer hits the soil retainer and scratches the root.

[Means for Solving the Problems]

Therefore, the present invention proposes a gauge wheel that is grounded and rolled on the upper surface of the ridge at a position below the front of the foliage processing unit that clamps the foliage of the underground stem crop to be planted in the ridge and transfers it to the upper rear. In the foliage processing machine arranged side by side on both sides of the section, overlaps with the gauge foil in side view, and is included in the gauge foil on both sides of the foliage section in plan view and exists above the ground plane of the gauge wheel. The above problem is solved by providing a root drop guide rod having two rods extending forward and backward.

[Action]

By taking the above means, the root of the rhizome planted in the ridge is kept in the ridge due to the pressure of the gauge foil and the resistance of the soil, and the foliage is pinched by the foliage treatment section and transferred to the upper rear. During the foliage processing work that is carried out while pulling out the foliage, the foliage part is provided with a root drop guide rod consisting of two rods that extend back and forth at a position apart from the upper surface of the ridge across the foliage part. Even if the roots are incompletely placed and come up on the foliage, the roots are removed by the roots drop guide rod, so the roots are not The situation of being transported together disappears.

〔Example〕

Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings.

First, as shown in FIG. 2 and FIG. 3, the schematic structure of the foliage processing machine is as follows.
To form a machine frame 1 by projecting the rear frame 1b toward the front lower side from both side portions of the front end, and a traveling portion having the engine 3, the transmission 4, the wheels 5, the handle 6 and the like as main constituent parts at the rear portion of the machine frame 1. 2 is provided, and the foliage processing unit 7 is mounted on the machine frame 1 in front of the traveling unit 2 to form the foliage processing unit 7.

The foliage processing part 7 is a scraping device 8 for scraping the foliage part above the ridge of the rhizome crop A backward, and the scraped foliage part is clamped at the front part and pulled backward while being transferred upward. , A pinching device 9 for transferring the extracted stem-leaved leaf portion further upward and rearward,
An upper conveying device 10 that inherits the extruded leaf portion transferred by the pinching device 9 and conveys it obliquely rearward is provided in an inclined shape from the front lower part to the upper rear, and the upper conveying device 10 A collecting / releasing device 11 having a collecting / releasing shutter 12 capable of collecting the stem-leaved leaves conveyed and carried out by the end of the trailing end and discharging the collected leaves to the ground every time a fixed amount is collected.
It is composed of the one provided with. The pinching device 9
Supports a pair of sprocket shafts 13 and a sprocket drive shaft 14 on both sides in front of and behind the machine frame 1 or this connecting member, and winds an endless belt with a wave protrusion made of an elastic material between the shafts 13 and 14. Then, the meshing portions for meshing the wave protrusions of the pair of endless belts with wave protrusions 15 at the adjacent portions are configured to advance in the same direction.

On the other hand, below the front portions of the pair of endless belts 15 with wave protrusions, and on both sides in the vicinity of the central portion of the pair of front frames 1a on both sides, there are arranged gauge wheels 16 that roll on the upper surface of the ridges. 1a or this connecting member is attached so that the vertical position can be adjusted. Accordingly, the relative distance between the foliage processing unit 7 and the gauge wheel 16 in the vertical direction is changed and adjusted so that the front end portion of the pinching device 9 is positioned slightly above the ridge, so that the root of the foliage portion above the ridge is less likely to break. It can be pinched near. The gauge wheel 16 has the function of adjusting the height of the foliage processing section 7 including the pinching device 9 and pressing the root of the ridge to keep it inside.

On the other hand, the power of the engine 3 is decelerated by the transmission 4 and transmitted to the wheels 5 on both sides, and also transmitted to the pinching device 9, the upper transfer device 10 and the scraping device 8 via the sprocket drive shaft 14. Has been done.

By the way, in the present invention, the above-mentioned foliage processing machine is provided with a root dropping guide rod 17 (FIGS. 1 to 3).

That is, the root drop guide bar 17 is located below the front part of the pair of endless belts with wave protrusions 15 and above the ridge upper surface by a required dimension (in relation to the gauge wheel 16, the center of rotation of the gauge wheel 16 in side view). Two rods, that is, a pair of left and right rods or tubing, are juxtaposed on both sides in the longitudinal direction in the front-rear direction with a narrow width of l, and the front portion It is formed by bending from the middle position so that it extends laterally on both sides as it goes forward and the distance between the front ends is L dimension. The root drop guide bar 17 may be bent until the front part becomes horizontal as shown in the embodiment.

Next, the root dropping guide rods 17 are attached by fixing the movable plates 18 to the outer sides at the respective rear end portions thereof, and fixing the movable plates 18 to each other.
A pair of fasteners 2 such as bolts and nuts on a pair of mounting seats 19 projecting forward slightly downward from both sides of the front center of the rear frame 1b.
It is fixed at 0. At this time, a long hole that is long in the left-right direction is formed in each mounting seat 19 in the front-rear position, and the mounting position of the movable plate 18 is changed along the long hole 21 so that the root portion integrated with the movable plate 18 is dropped. The distance between the guide bars 17 can be adjusted to a desired size.

Although not shown, the root drop guide bar 17 may be attached by an automatic tension structure such as a spring or by a structure capable of rotating right and left to a desired angle.

In addition, in the figure, 22 is a pair of grass bodies that are paired at the foremost ends on both sides of the front frame 1a, 23 is a sled body that is arranged in a little direction of each grass body 22, 24 is a protective cover, and 25 is a ridge. It is a coated mulch film.

According to the above, first, the root of the rhizome plant A planted along the ridge is kept in the ridge due to the pressure of the gauge foil 16 or the resistance of the soil, and only the foliage is pulled out before the foliage treatment work is started. Taking into consideration the situation, the mutual intervals of the root drop guide rods 17 are changed and adjusted to be proper intervals, and then the engine 3 is started to move the machine forward along the ridges. The foliage of the foliage is scraped rearward by the scraping device 8, the front ends of the pair of endless belts with wave protrusions 15 are clamped near the roots of the foliage, and the foliage is moved forward and upward while being forwardly inclined. When pulling out, the pair of root drop guide bars 17 on both sides of the foliage part guide the foliage part by the front spreading part of the front part without hooking the mulch film 25 covering the ridge surface. Since it leads to the narrow rear part, it is attached to the foliage Even root portion came up to the ridge, the root portion is dropped Sugoki at intervals of the roots village guide rods 17, suitably separation takes place. Then, the stem-leaved portion pulled out to the upper rear is further transported to the upper rear, is inherited by the upper conveying device 10 from the rear end thereof, and is conveyed obliquely rearward, and is horizontally oriented from the rear end. Collection and release shutter 1
Each time a fixed amount is collected, the collecting / discharging shutter 12 is switched to the drooping position to be discharged to the ground, and then returned to the collecting position again, and then the collecting and discharging are repeated in the same manner to perform the foliage treatment. Work is being done.

[Effect of device]

As is clear from the above description, the present invention has a root drop guide rod consisting of two left and right rods with a space between them at the front lower position of the foliage processing unit that pinches and conveys the foliage. Since it overlaps with the gauge foil in side view and is included in the gauge foil on both sides of the foliage in plan view, the root is held in the ridge by the resistance of the soil or the pressure of the gauge foil, and only the foliage is pulled out. Even if the root part accidentally comes up on the foliage part during the work to go, the root part is passed through between the root part drop guide rods, so the root part is wiped off by the root part drop guide rods. At this time, since the root drop guide bar is provided close to the gauge wheel in the front-rear position, this effect is more reliable. Further, since the root drop guide bar is provided at a position separated from the upper surface of the ridge by a required dimension, it does not come into contact with the upper surface of the ridge, and the mulch film covering the upper surface of the ridge is not hooked. Further, since the interval between the root dropping guide rods can be changed widely, the interval can be changed and adjusted to an optimum size according to the root to be harvested, and variation in the planting position in the width direction can be dealt with.
