Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a straightening structure for improving straightness of a foliage processing machine that pulls out the foliage of a rhizome such as potato planted along a ridge, leaving its root.

[0002]

[Prior art]

 An example of this type of foliage processing machine is shown in Japanese Patent Publication No. 59-39084. That is, the foliage is pinched by an endless belt and transferred to the rear to pull it out, and the machine body is supported by wheels rolling on both hem surfaces of the ridge.

[0003]

[Problems to be solved by the device]

 Since subterranean crops are usually formed into ridges and planted in them, the machine must move along the ridges in order for the foliage processing machine to smoothly process the foliage. For this purpose, a structure for ensuring the ability to follow the ridges (straightness) is required, but such a structure is not found in the above-mentioned prior examples.

However, a sliding plate that slides on the upper surface of the ridge is provided on the front part of the airframe, and this sliding plate literally slides on the upper surface of the ridge to enhance the residual effect of the root in the soil. However, it does not ensure straightness, and even if one tries to do so, it cannot. The present invention solves such a problem and enhances the straightness of the airframe and reduces the running resistance.

[0005]

[Means for Solving the Problems]

 Under the above problems, the present invention collects the foliage processing device that pulls out the foliage of the rhizome planted in the ridges and conveys it upward and backward, and the foliage that has been conveyed from the foliage treatment device. In a foliage processing machine where the collecting and discharging device for discharging is mounted on a machine with wheels at the rear of the ridge that roll on both skirts of the ridge, the front of the machine rolls over the top of the ridge. The present invention provides a structure for improving straightness of a foliar treatment machine, which is characterized by being supported by two right and left gauge wheels arranged in a V shape.

[0006]

[Action]

 The present invention takes the above measures, that is, the front part of the machine body is supported by the two left and right gauge wheels facing the inverted C-shape when viewed from the front, which rolls on the upper surface of the ridge. The foil acts to hold the ridges, preventing the aircraft from slipping and improving straightness. In addition, since the gauge wheel rolls, it reduces the running resistance of the machine body, which also contributes to the improvement of linearity.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of the foliage processing machine, and FIG. 2 is a front view of the foliage processing machine. The foliage processing machine has a traveling section mainly including an engine 3, a mission 4, wheels 5, a handle 6 and the like at the rear of the machine body 1. 2 is provided, and a foliage processing device 7 is installed from the front part of the running part 2 to the central part, and a collecting and discharging device 8 is installed in the central part.

The foliage treatment device 7 includes a scraping device 9 that scrapes backward the foliage part above the ridge of the rhizome crop A, and a scraping device 9 that clamps the scraped foliage part and transfers the foliage part upward to the rear. A pulling and pinching device 10 and a transporting device 11 that inherits the foliage portion transferred by the pinching device 10 and further transports it further rearward and upward are provided in a backward rising slope in order from the front part to the rear part. It

Of these, the scraping device 9 is a device in which a pair of left and right circular belts 12 with protrusions are arranged rearward and upward in a state where the facing surfaces are overlapped with each other, and are rotated so that the overlapping portions move together backward. Is. The scraping device 9 is a device in which the overlapping portion of the belt 12 with protrusions acts on the foliage of the rhizome crop A, scrapes it, and sends it to the subsequent pinching device 10.

The pinching device 10 has a pair of left and right oval belts 13 with wave protrusions arranged rearward and upward with the opposing surfaces meshing with each other, and rotated so that the meshing parts together move backward. Is. The pinching device 10 transfers the foliage portion scraped by the scraping device 9 to the rearward and upper side by meshing with the meshing portion of the belt 13 with wave protrusions, and transfers it to the succeeding conveying device 10.

In this case, two gauge wheels 14 rolling on the upper surface of the ridge are installed below the pinching device 10, that is, on the both sides of the central part of the body 1 below the front part of the belt 13 with wave protrusions so that the vertical position can be adjusted. To be done. The gauge wheel 14 adjusts the height of the stem and leaf processing device 7 including the pinching device 10, and also presses the root portion of the ridge of the rhizome plant A and keeps it in the soil.

For this reason, the gauge wheel 14 is composed of a relatively wide roller and is oriented in an inverted C-shape when viewed from the front (see FIG. 2). By doing so, the gauge wheel 14 holds the ridges and suppresses the displacement of the machine body 1 from the ridges, so that the ability to follow the ridges, that is, the straightness is improved. At the same time, since the pressing force of the gauge wheel 14 is directed in the normal direction, the effect of remaining in the dark blue portion is increased.

The transporting device 11 is a device in which a pair of left and right elliptical belts 15 with protrusions are arranged in a rearwardly upward manner with their facing surfaces being overlapped with each other, and are rotated so that the overlapped portions are moved backward together. The conveying device 11 is to inherit the foliage portion transferred by the pinching device 10 at the overlapping portion of the belt 15 with protrusions, convey it to the upper rear, and drop it on the subsequent collecting and discharging device 8.

The collecting / discharging device 8 collects a certain amount of the foliage portion conveyed by the conveying device 11 and discharges it to the ground. The collecting / discharging device 8 includes a substrate 16 provided between the transport device 11 and the engine 3, and a discharging shutter 17 attached to both sides of the substrate 16.

The left and right discharge shutters 17 are designed so that they can be switched between a horizontal position and a drooping position. The foliage is collected in the horizontal position, and when the collection amount becomes constant, it is manually operated or its weight is used. It is a mechanical automatic operation that switches to a drooping posture and releases it to the ground. The postures of the left and right discharge shutters 17 are alternately switched, and the rear end of the transport device 11 can also be swung left and right in conjunction with this switching, but the details thereof are omitted here. .

In addition, on the left and right of the front part of the machine body 1, there is provided a grass body 18 which divides the foliage portion to be treated from the foliage portion which is not to be processed, and a little behind the grass body 18 is grounded on both hem faces of the ridge. A sled body 19 that slides on the ground is provided. Furthermore, the upper part of the pinching device 10 is covered with a protective cover 20, and the upper surface of the ridge is covered with a mulch film 21. By the way, since the sled body 19 is in contact with both skirts of the ridge, it contributes to enhancing the straightness of the machine body 1, like the gauge wheel 14.

In order to pull out the foliage of the underground crop A with this foliage treatment machine, the wheels 5 are driven by the engine 3 to move the machine body 1 forward along the ridges. Then, the foliage is scraped backward by the scraping device 9, is pulled out by the pinching device 10, and is transported to the collecting and discharging device 8 by the transport device 11. During this time, the root remains in the ground.

By the way, when pulling out the foliage, most of the root is kept in the soil due to the resistance of the soil and the action of the gauge foil 14, but some of the roots come up along the foliage. It is the root drop guide bar 21 provided below the pinching device 10 that drops this. The root drop guide rod 21 is made up of two rods arranged in parallel inside the gauge wheel 14 so that the foliage pulled out by the pinching device 10 passes between the rods. It is a thing. Therefore, if the foliage has a root, it can be reliably wiped off by the root dropping guide bar 21.

The foliage that has been transported by the transport device 11 is dropped onto the discharge shutter 16 of either the collecting and discharging device 8 which is in the horizontal position (the rear end of the transport device 11 is also swung to that side). A predetermined amount is stored on it. When the stagnant amount of the foliage reaches a certain amount, the discharge shutter 17 is manually or automatically switched to the hanging posture, and the foliage is discharged to the ground.

[Effect of device]

 As described above, according to the present invention, in the foliage processing machine having the above-mentioned structure, the front part of the machine body is supported by the two right and left gauge wheels that are oriented in an inverted V shape when viewed from the front and roll on the upper surface of the ridge. Therefore, the gauge wheel acts like holding a ridge, and enhances the straightness of the aircraft. In addition, since the gauge wheel rolls, it contributes further to reducing the running resistance of the aircraft and improving straightness.
