[0003]

According to such a foliar processing machine, the foliage above the ridge is raised by a pair of guides, and the ground on both sides of the foliage is grounded only at the root by a pair of soil holding bodies. It is inserted between a pair of endless conveyor bodies in a state where the soil is held down so as to keep it, and the foliage is pulled out while being transferred upward and rearward with the rotation of the endless conveyor body, If the function of the soil holding body is not sufficient, the root is transported with the root attached to the foliage. Further, when the ridge surface is covered with the multi-film, the earth pressing body sliding on the multi-film may catch the multi-film. The present invention has been made to solve such a problem, and is intended to surely drop the root without damaging the root.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a foliage processing section for retaining a root of a rhizome crop planted in a ridge in a ridge, sandwiching the foliage, and transferring the foliage upward. A collecting / discharging device that collects a certain amount of foliage transferred from the foliage processing unit and discharges it to the ground is located below the end of the processing unit. In a walking type foliage processing machine in which gauge wheels that roll and roll are arranged on both sides of the foliage, they are located above the grounding surface of the gauge foil in side view and polymerize with the gauge foil. It has a shape in which two rods that are included in the gauge foil on both sides of the foliage in plan view and have a gap that does not pass through the root transferred with the foliage extend back and forth. A walking-type foliage plant provided with a root removing guide bar. It is to provide a root village and guide bars of the machine.

[0005] By taking the above measures, the roots of the rhizome crops planted on the ridges are retained in the ridges by the pressure of the gauge foil or the resistance of the soil, and the foliage is pinched by the foliar processing part and then upward. At the time of foliage processing work to pull out while transferring toward, by providing a root drop guide rod consisting of two rods extending back and forth at a position away from the upper surface of the ridge across the foliage, The foliage will rise between the root dropping guide rods, and even if the root placement is incomplete and it comes up with the foliage, it will be scraped off with the root dropping guide rod, so the root This eliminates the situation in which is extracted together with the foliage. In this case, since the root dropping guide rod is separated from the foliage processing part up and down as it goes backward, the force of scraping is gradually applied as the foliage is transferred backward, and the root is damaged. Less is.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, as shown in FIGS. 2 and 3, a schematic configuration of a walking type foliage processing machine according to the present invention includes a pair of front frames 1 a made of a tube material, a bar material, etc. A machine frame 1 is formed so as to protrude toward the machine frame 1, and a traveling unit 2 having an engine 3, a transmission 4, wheels 5, a steering wheel 6, and the like as main components is provided at a rear portion of the machine frame 1. 1 and is formed by mounting a foliage processing unit 7 on it.

[0007] The foliage processing unit 7 includes a scraping device 8 for scraping the foliage above the ridge of the subterranean stem crop A to the rear, and the stalked foliage being clamped at the front part and transferred upward and rearward. A pinching device 9 for transporting the extracted stem portion further rearward and upward, and an upper conveying device for inheriting the stem portion transferred by the clamping device 9 and transporting the stem portion obliquely rearward. The device 10 and the rear are provided in an inclined shape in order from the lower front to the rear upper,
A collecting and discharging device 11 having a collecting and discharging shutter 12 capable of collecting the extruded leaves conveyed and transmitted by the upper conveying device 10 and discharging the collected leaves to the ground every time a certain amount is collected is disposed below the upper transfer device 10. And so on.

The pinching device 9 supports a pair of sprocket shafts 13 and a sprocket drive shaft 14 on both sides before and after the machine frame 1 or its continuous member. The meshing portions wound around the shafts 13 and 14 and meshing the wave projections of the pair of endless belts 15 with the wave projections at adjacent portions advance in the same direction.

On the other hand, a pair of endless belts 1 with wave projections
5, a gauge wheel 16 rolling on the upper surface of the ridge is disposed on each side near the center of the pair of front frames 1a on both sides, and each gauge wheel 16 is vertically positioned on the front frame 1a or this continuous member. Mounted change-adjustable. Thus, by changing and adjusting the relative distance in the vertical direction between the foliage processing unit 7 and the gauge foil 16 so that the front end of the pinching device 9 is slightly above the ridge upper surface, the root of the foliage above the ridge is hardly broken. It can be pinched near.

[0010] The gauge wheel 16 is connected to the clamping device 9.
And the height of the foliage processing unit 7 including
It acts to hold down the root in the ridge and keep it inside. The power of the engine 3 is reduced by the transmission 4 and transmitted to the wheels 5 on both sides, and transmitted to the pinching device 9, the upper transfer device 10 and the scraping device 8 via the sprocket drive shaft 14. Have been.

According to the present invention, the walking type foliage treatment machine as described above is provided with the following root removing guide rod 17 (FIGS. 1 to 3). FIG. 1 is a plan view of a main part of the root dropping guide rod 17. The root dropping guide rod 17 is located below the front part of the pair of endless belts 15 with wave projections and at a position above a ridge upper surface by a required dimension (gauge). In relation to the foil 16, two rods, that is, a pair of left and right rods or pipes, are placed on both sides of the foliage at the center of rotation of the gauge wheel 16 in a side view, and the longitudinal direction of each of the two rods. Are formed side by side with a narrow l dimension in the direction, and are bent from the middle part so that the front part expands to the left and right on both sides as going forward, and the distance between the front ends becomes L. It is. Note that the root dropping guide bar 17 may be bent until the front portion becomes horizontal as shown in FIG.

Next, installation of the root dropping guide rod 17 is as follows.
A movable plate 18 is fixed to each rear end of the movable frame 18 outwardly, and bolts and nuts are mounted on a pair of mounting seats 19 projecting forward and slightly downward from both sides of the front end central portion of the rear frame 1b. The fixing is carried out with the fastening tool 20. At this time, a long hole 21 long in the left-right direction is formed in each of the mounting seats 19 at the front and rear portions, and the mounting position of the movable plate 18 is changed along the long hole 21 so that a root integral with the movable plate 18 is formed. Buraku Guide Rod 17
Is changed and adjusted to a desired size. Although not shown, the root drop guide rod 17 may be attached by an automatic tensioning structure using a spring or the like, or may be attached by a structure that can rotate to a desired angle right and left. In this case, the root dropping guide rod 17 is formed slightly upward from the substantially horizontal position, but with the foliage processing section 7 which is inclined obliquely upward and rearward, the vertical interval increases (separates) toward the rear. (Figure 2).

In addition, in the figure, reference numeral 22 denotes a weed body disposed at a pair of frontmost ends on both sides of the front frame 1a, 23 denotes a sled body disposed slightly behind each weed body 22, 24 denotes a protective cover, and 25 denotes a ridge. It is a multi-film coated surface.

According to the above description, first, before starting the foliage processing operation, the root of the rhizome crop A planted along the ridges is retained in the ridges by holding down the gauge foil 16 or the resistance of the soil to pull out only the foliage. In consideration of the condition of planting, etc., the distance between the root dropping guide rods 17 is changed and adjusted so as to be an appropriate distance. Then, the engine 3 is started and the machine is advanced along the ridge. The foliage of the crop A is scraped rearward by the scraping device 8, and a pair of endless belts 1 with wave projections is provided.
When the front end of 5 is strung near the root of the foliage and pulled out while transporting in a forwardly inclined posture toward the rear upper,
The pair of root dropping guide rods 17 on both sides of the foliage guides the foliage at the front spread portion and guides the foliage to the narrow rear portion without catching the multi-film 25 covering the ridge surface. Even if the roots rise up to the ridges on the foliage, the roots are sharply removed at intervals of the root dropping guide rods 17 and the separation is suitably performed. In this case, since the foliage processing section 7 and the root dropping guide rod 17 are in a relationship in which the vertical distance increases as going backward, the transfer force is gradually converted into a sweeping force, and the sweeping force is sharply reduced. There is little chance of damaging the root without applying any force.

[0015] The stems and leaves that have been pulled upward and rearward are further transported upward and rearward, are inherited from the rear end by the upper transport device 10 and are transported obliquely rearward. The shutter is gradually discharged onto the collecting and discharging shutter 12 in a horizontal position, and the collecting and discharging shutter 12 is switched to the hanging position and discharged to the ground every time a fixed amount is collected, returned to the collecting position again, and so on. By repeating the above, the foliage processing operation is performed.

[0016]

As is apparent from the above description, the present invention provides a root consisting of two right and left rods spaced apart from each other at a position below the front part of a foliage processing part which conveys a foliage by pinching. Since the drop guide rod is superimposed on the gauge foil on the side view, it is included in the gauge foil on both sides of the foliage in plan view, so that the root is kept in the ridge by soil resistance and holding down the gauge foil, and the foliage During the work of pulling out only the root part, even if the root part comes up with the foliage by mistake, the foliage passes between the root dropping guide rods, so the root part is amazing with this root dropping guide rod Dropped. In this case, since the foliage processing section and the root dropping guide rod are in a relationship in which the vertical distance increases as going backwards, the scoping is performed gradually, and there is little chance of damaging the root.

Further, since the root dropping guide rod 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 does not catch the multi-film covering the upper surface of the ridge. Furthermore, if the distance between the root drop guide rods can be changed widely, the distance can be changed and adjusted to the optimum size according to the root to be harvested, and it can cope with variations in the width direction of the planting position and the like. .
