Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head vegetable harvester, such as cabbage, having a relatively thick and long stem root below a head part.

[0002]

2. Description of the Related Art Recently, harvesters for harvesting various kinds of vegetables have been put into practical use, and head vegetables are no exception. In addition to cabbage, cabbage includes cabbage, lettuce, etc., and head cabbage has relatively thick and long roots buried under the head in the ground. .
Therefore, when the head portion is pulled out by grasping the head portion, the head portion may be damaged due to pull-out resistance.

[0003] For this reason, there has been proposed a method of pulling out such a strong stem root by pinching or clamping (Japanese Patent Laid-Open No. 8-3).
No. 7879, JP-A-9-74865). These have two auger screws arranged side by side at the front of the fuselage in the front-rear direction, and rotate the auger screw (rotate the opposing side downward to pull the stem root downward). The roots are taken up between the valleys and dug up, and transported upward and backward.

[0004]

In such a mode in which the auger screw is rotated to convey while pulling the stem root downward, there is a case where the headed vegetables jump on this and the conveying posture is deteriorated. Further, the head portion may be scratched by being rubbed by the auger screw. In addition, since the two auger screws are fixedly provided in order to exert a holding force, if a stone or the like is caught between them, the auger screws may be damaged. In view of this, the present applicant has proposed a method in which the stem root portion below the pinching point while being rubbed is conveyed by being pinched with a chain-shaped one (Japanese Patent Application No. 2000-2991).
It has a corresponding effect.

[0005] On the other hand, in order to stably transport the extracted head vegetables, it is essential to stabilize their posture. if,
If the product is transported with its posture unstable, it may drop on the way,
It will lose its shape. In addition, this type of harvester usually harvests the head vegetables dug up on the ground in a state where the roots of the roots of the shipping form are cut, so that the posture is stable even during this cutting. Is very important. That is, if the conveyance posture is bad, the cutting position (height) is not uniform, and the quality is not stable. what if,
If the cutting height is too high, the head will be cut deeply,
It will abandon useful parts, and if it is too low it will leave roots that are not edible.

For this reason, in addition to the above-described transport mode, there is a type in which the upper side or the side of the head portion is sandwiched by a belt-shaped material to stabilize the posture, but the above-mentioned shoot root is unstable. In such a case, in order to overcome the cutting resistance, the pinching force must be considerably increased. In this case, the head portion is damaged or loses its shape, which again causes a drop in commercial value.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. First, in the process of pulling out and transporting a stem root portion in a state of being stuck in a stationary manner, the bottom of a head portion is rubbed while being rubbed. It is intended to stabilize the posture. That is, the stem root portion and the head portion are supported in two steps, upper and lower, to prevent posture collapse. In this case, at the time of cutting the stem root portion, the portion above the supported portion is cut so that no abrasion or the like remains. In the second aspect of the present invention, the root of the stem is pinched in two steps, and the pinching force is changed by the upper and lower pins, thereby further stabilizing the posture and being convenient for cutting the root of the stem. It is like that.

[0008]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a stem root pulling and conveying apparatus for grasping and pulling the root of a headed vegetable planted in a field while traveling, and conveying the diagonally upward rearward. The head crop harvesting machine having a stalk guide for guiding the stalk roots between the roots of the heads when the stalk roots are inserted therebetween and rubbing the bottoms of the heads in the heads. Is provided.

In the present invention, since the stem root is pulled out and transported by the stem root extracting / transporting device, the transporting force is strong and the posture is stable. Here, the term “trapping” means that the root extraction pulling and conveying device is stationary against the root of the stem, and is different from the method in which the screw is rotated to convey while rubbing. On the other hand, in the case of transporting only by pinching the stem roots, the stability of the posture may be lacking. Therefore, in the present invention, the guide is performed while rubbing the bottom of the head portion with a rubbing guide. Posture stability is maintained by this.

[0010] As the rubbing guide for this purpose, a wide guide whose upper part in the direction perpendicular to the conveying surface is convexly curved is preferable. This is because the contact area is increased to reduce the sliding resistance, to contribute to the stability of the posture, and to reduce the damage of the head portion. Therefore, it is preferable that the radius of curvature is large, and that the surface is finished smoothly.

[0011] The present invention also relates to a head and vegetable harvesting machine having a root and root pulling and conveying device for pinching and pulling the root of a head of vegetable grown in a field while traveling, and for conveying the diagonally upward. Below the pulling and conveying device, there is provided a lower root and root pulling and conveying device which straddles the lower part of the stem and conveys the diagonally upward afterward. It is characterized in that the pinching force is set to be less than the degree and the pinching force is set to be stronger than the pinching force of the stem root extracting and conveying device, so that the root of the stem is slipped down from the root extracting and conveying device. Provide head cropping machine.

[0012] Thus, since the root portion is conveyed while being pinched and conveyed in two vertical stages by the root pulling and conveying device and the lower root extracting and conveying device, it becomes more resistant to the posture collapse force. It further contributes to posture stability. In addition, if the inclination of the lower root extraction device is set to be lower than the inclination of the root extraction device, the pinching force is set to be stronger than the clamping force of the root extraction device. Since the stem root can be lowered from the stem root pulling and conveying device as it is conveyed backward, it is possible to align the vertical height of the head with respect to the stem root pulling and conveying device, and reduce the height of cutting performed later. Can be unified.

In this case, the provision of the above-mentioned rubbing guide makes it possible to rub the bottom of the bulb portion and make it necessary for the guide, so that the drawing height does not have to be set strictly. Thus, the initial setting operation of the pedicle root pulling and conveying device becomes easy. That is, if the lower part of the stem root is slightly straddled at first, the bottom of the bulbous part is rubbed, which is necessary for the guide.

Further, according to the present invention, the speed of the lower root extraction device is set to be higher than the speed of the root extraction device, and the posture of the root is changed as the root is transported backward. Means are provided so as to be nearly perpendicular to the transport plane of the device. Since the root of the shoot is buried almost vertically in the ground, unless the posture is changed, the root of the shoot is inclined with respect to the transport plane of the head transport device, and sufficient pinching force does not appear, and Resistance is also insufficient. However, this problem can be solved by taking the above measures.

The rotating surface of a disk cutter generally used as a cutting device is mechanically set to be parallel to the transport plane of the shoot root extracting and transporting device, so that the shoot root is inclined with respect to this plane. In this case, the cutting height is not constant, and the cut surface and the cutter surface are not parallel, and the cut surface is in a state of being scraped off, so that a sharp cut surface with high commercial value is not obtained. However, these disadvantages can be eliminated by performing the above.

Further, the present invention relates to a method for removing the above-mentioned bottom portion of the head portion hitting the shoot root pulling and conveying device or the bottom of the rubbed guide when there is a rubbing guide. Means are provided in which a cutting device for cutting the stem and root is provided. As described above, this type of harvester harvests a cut head vegetable with a specific portion cut, but in this case, the outer leaves hanging on the base of the shoot root and the outside of the head (this is a demon) (Called a leaf) at the same time. Therefore, if the upper part is cut off from the bottom that has hit the stem root pulling and conveying device or the bottom that has been rubbed by the rubbing guide, it is possible to remove the demon leaves and leave no scratches generated when it is applied or rubbed. .

[0017]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a head vegetable harvester (hereinafter, a harvester) showing an example of the present invention, FIG. 2 is a partial plan view of a pull-out transport portion, and FIG. 3 is a partial plan view of a main portion of the pull-out transport portion. However, this harvester has one side of one side of the self-propelled body 2 equipped with the crawler device 1 (in this example, the left side in the traveling direction).
In addition, a pedicle root pulling and conveying device 3, a lower pedicle root pulling and conveying device 4 and a head portion conveying device 5 are provided.

The root extraction and transport device 3 pulls the root 6a of the head vegetable 6 planted in the field by pinching it, and transports it diagonally upward and backward. And a pair of moving bodies 7 whose opposite sides rotate backward. The moving body 7 of this example shows a chain 7 having small projections protruding on the opposite side, and is hung around front and rear sprockets 8 and 9 to be rotated (the rear sprocket 9 is the driving side). The front sprocket 8 has
On its upper and lower surfaces, a star wheel 10 and a cup body 11 whose diameter is slightly smaller than that of the lower surface are spherical.

The above sprocket 8 (star wheel 10)
And the cup body 11) are attached to the frame 14 by arms 12 and 13, respectively. One arm 12 (left side in the traveling direction) can rotate around a pin 15 provided on the frame 14. And is always urged by a spring 16 toward the other party. In the case where a large object is bitten, it is possible to escape to the outside and pass by.

Further, the chain 7 on one side (also on the left side)
It can be evacuated to the outside for the same purpose. That is, the chain 7 is provided with a chain tension 17 for tensioning the opposite side (inner side) to the other party (a similar chain tension 18 is also provided to the other party), but the chain tension 17 on this side is provided. Can be made to advance and retreat, and it is urged to the other party by the spring 19. In any chain 7, the opposite outer portion is stretched with chain tensions 45 and 46 in order to maintain the tension, but when the arm 12 escapes or the inner chain tensions 17 and 18 retreat, Naturally the tension changes. For this reason, the chain tensions 45 and 46 can be repositioned by being urged freely.

Above the chain 7, there is provided a rubbing guide 20 for guiding the stem root portion 6a of the bulbous vegetable 6 therethrough and rubbing the bottom of the bulbous portion 6b.
The rubbing guide 20 of the present example starts from around the rear end of the star wheel 10 and continues to the vicinity of the end of the chain 7. Is what it is. Further, it is preferable that the rubbing guide 20 has its front end lowered so as to be sunk under the star wheel 10 and is opened in an octagonal shape for taking in and guiding the root portion 6a.

Below the shoot root extraction / transport device 3, a lower shoot root extraction / transport device 4 is provided. The lower shoot root extraction / transportation device 4 includes a shoot root portion 6 pinched by the shoot root extraction / transportation device 3.
The lower part a is struck further below, and is composed of a moving body 21 that moves rearward and rises on an inclined surface in the same manner as the pedicle root pulling and conveying device 3. In the moving body 21 of this example, only one (right side) is a chain 21 with a projection, and the other is a bar 22 that presses against this.
It is composed of

The chain 21 with projections is also wrapped around the front and rear sprockets.
Is also used for the chain 7 on the right side of the root extraction pulling and conveying device 3 (therefore, this is the driving side), and a dedicated sprocket 23 is provided only at the front. On the other hand, the bar 22 is elastically urged by the spring 24 to the protruding chain 21 so as to tightly clamp the stem root portion 6a therebetween, but can be tilted back and forth in plan view. . This is for enabling smooth passage of the root part 6a.

In the present embodiment, the inclination of the lower root extraction device 4 is set to be smaller than the inclination of the root extraction device 3. Although the degree cannot be limited, the difference between the start end and the end is set to be different by about 5 to 50 mm. Further, the pinching force in the lower root extraction and transfer device 4 is made stronger than the pinching force in the root extraction and transfer device 3, and the root 6a that is conveyed while being pinched and transported by both of them is caused by the difference in the inclination described above. It is configured so that it can be slid down from the upper shoot root extraction and transfer device 3.

This is for the purpose of ensuring that the head 6 is lowered before leaving the root extraction pulling and conveying device 3 and that the bottom of the head 6b always hits the rubbing guide 20. This is for stabilizing the posture of the rhizome 6b and unifying the cutting position of the rhizome 6a described later. Further, the speed of the lower root extract pulling and conveying device 4 is set to be higher than the speed of the root shoot pulling and conveying device 3, and the speed difference allows the rhizome 6a erected and buried upright in the ground to be pulled upward as it is. The falling posture of the pedicle root pulling and conveying device 3 based on the conveying plane is corrected so as to be close to a right angle. This is for improving the transportability and the cutting property.

In the vicinity of the rear end of the root extraction device 3, the root 6 a which is conveyed by being pinched and transported by the root extraction device 3 and the lower root extraction device 4 as described above.
Is provided with a cutting device 25 that cuts the sheet. The cutting device 25 of the present example is composed of two disks, a disk cutter 26 that is forcibly driven and a disk blade 27 that is rotatably provided side by side with the disk cutter 26. The base and the demon leaves 6c hanging around the bulbous portion 6b are cut off. The plane of rotation of the disk cutter 26 is set substantially parallel to the plane of rotation of the pedicle root pulling and conveying device 3 (the lower pedicle root pulling and conveying device 4 is also substantially the same).

A head transporting device 5 is provided above the stem root pulling and transporting device 3, from around the rear portion of the star wheel 10 to the rear portion of the body 2. The head transporter 5 includes a head 6b of the head vegetable 6 pulled out by the root puller 3
And conveys it to the rear of the body 2 from a pair of moving bodies 28 that oppose each other in a rearwardly inclined plane that is substantially parallel to the pedicle root pull-out and conveying device 3 and whose opposite sides rotate backward. Become.

The moving body 28 of this embodiment is composed of a belt 28 made of an elastic material which does not damage the ball-shaped portion 6b, and is rotated around front and rear rollers 29, 30 (the rear roller 30 is on the driving side). ing. In addition, both belts 28 are in rolling contact with a number of rollers 31 for direction control and tension. In this case, the opposite side (inside) of one (left) belt 28 is outward. I am running away. This is to provide a strong pinching force regardless of the size of the head portion 6b.

Specifically, a specific roller 31 is connected to the arm 3
2 and a pin 3 provided on the frame 14
3, which is stretched by a spring 34. The start end and the rear end of the belt 28 both have an open-ended octagonal shape in plan view, so that the head portion 6b can be taken in and out smoothly. However, before reaching the cutting device 25 described above, this figure-of-eight is already closed, and the head transporting device 5 holds the head 6b.

On the other hand, in the present embodiment, the pedicle portion 6a and the demon leaf 6 are located immediately below the belt 28 constituting the head transporting device 5.
A moving support 35 is provided to support the c while moving the bottom of the cut head portion 6b. This is for stabilizing the posture of the head portion 6b which is conveyed while being held by the belt 28. The moving support 35 of the present example is configured by a soft elastic round belt 35 having a circular cross section, and is hung around front and rear rollers 36 and 37 to rotate at the same speed as the belt 28. . The opposite side of the round belt 3 moves on the rail 38 to prevent it from hanging down.

In both round belts 35, the rear roller 37 is connected below the roller 30 of the head transport device 5, and only the front roller 36 is provided. Further, rollers 39 for direction control and tension are provided as appropriate. The round belt 35 extends from around the rear of the cutting device 25 to near the rear end of the head transport device 5.

By the way, the round belts 35 are arranged at intervals so that the uncut stem roots 6a can be inserted therebetween.
For this reason, the one (right) round belt 35 is inserted between the belts 28 of the head transporting device 5, while the other (left) round belt 35 is inserted between the belts 28.
Round belt 35 is inserted at a position retracted from the running surface of belt 25 on this side. As described above, when the head portion 6a passes, the belt 28 on this side retreats. At this time, the round belt 35 is exposed between the belts 28 and supports the head portion 6b. The supporting point is set at a position substantially symmetrical to the left and right of the root portion 6a, depending on the size of the bulbous portion 6b.

In addition, below the rear end of the head transport device 5, a vertical transport device 40 comprising a belt conveyor for receiving the head portion 6b dropped from the head and sending it to the rear of the body 2 is provided.
On the right side of the vertical transport device 40, there is provided a horizontal transport device 41 composed of a belt conveyor that also feeds the right side.
Further, a transfer device 42 composed of a belt with projections for transferring the head portion 6b sent by the vertical transfer device 40 between the transfer devices 40 and 41 to the horizontal transfer device 41 is also provided.
Then, the head portion 6b sent by the horizontal transport device 41 is stored in a container (not shown) loaded on the right side of the body 2 (this work is usually performed by an assistant walking with the harvester. Do).

On the other hand, with respect to the drive system, a first drive shaft 43 driven by the engine is provided substantially at the center of the body 2, and the roller 30 on the drive side of the head transporting device 5, the pedicle pulling-out transporting device 3, It is distributed to the sprocket 9 on the drive side of the lower shoot root extraction / conveyance device 4, the disk cutter 26 of the cutting device 25, the vertical conveyance device 40, the horizontal conveyance device 41 or the transfer device 42 via a chain, a belt, and a rod. However, at this time, a bevel gear mechanism or the like is appropriately used if a direction change or the like is necessary.

Next, a method of harvesting the head vegetables 6 by the harvester having the above configuration will be described. FIG. 4 is a partial side view showing the relationship between the head vegetables 6 and the root extraction and transport device 3.
Generally, the head vegetables 6 are row-planted in a field with ridges (a is the ridgeline). Therefore, the star wheel 10 and the cup body 11 of the root-peel pull-out / transport device 3 act on the middle of the ridges. (B is its line of action). In this state, the harvester approaches the head vegetables 6 and takes in the shoot roots 6 a between the two star wheels 10. At this time, since the star wheel 10 needs to act below the head portion 6b, the height is adjusted by a gauge wheel 44 provided to be vertically adjustable.

In the star wheel 10, the peaks and valleys mesh with each other and the opposite side is forcibly driven backward.
The captured root portion 6a is smoothly sent out rearward, and is pinched by the chain 7 of the root portion pulling and conveying device 3. At this time, the cup body 11 prevents the tip of the pedicle root pulling and conveying device 3 from sticking into the soil, and the pedicle root 6a
To assist the sending out by the star wheel 10 except for the soil around. By the way, since the root 6a is pinched by the two roots 7 by the root pulling and conveying device 3, it is reliable and strong. However, the root 6a that is standing upright in the ground is placed in that posture. Because they are strung as they are,
The ball-shaped portion 6b is in a state of being inclined ahead of the rotation plane of the chain 7 (FIG. 1).

The root 6a, which has been caught by the chain 7, is conveyed rearward in that position, but is further caught below the bar by the protruding chain 21 and the bar 22 of the lower rhizome pulling-out device 4 from the middle. It is sent to the device 25 and the root of the stem root part 6a and the demon leaf 6c are cut. FIG. 5 is a cross-sectional view of the stem root extracting / conveying device 3 and the like showing the relationship with the heading vegetables 6. At this time, the inclination angle between the stem root extracting / conveying device 3 and the lower rhizome extracting device 4 is the latter. And the pinching force is set stronger in the latter, so that the root 6a slides down the root extraction and transport device 3 as it is transported.

However, since the above-mentioned rubbing guide 20 is provided above the root-of-stalk pull-out / transportation device 3, the head portion 6b does not fall any further upon contact with the rubbing guide 20, and the cutting position is unified. You. For this purpose, the shoot root 6a must be able to slide down between the chains 7 of the shoot root pulling and conveying device 3, but as described above, this chain 7 is provided with a small projection 7a. By doing so, the stem root 6a is pinched between the projections,
This becomes possible.

However, in rare cases, the projection 7a may pierce the rhizome 6a. Therefore, a vertical wall 7b is attached to the top surface of the projection 7a, and even if an attempt is made to pierce the projection, it is prevented by the vertical wall 7b. One (FIG. 7), one in which the chain 7 is replaced with an elastic belt 7 'having a projection 7'a to prevent piercing (FIG. 8), and the like can be considered. In this case, it is preferable that the protrusion 7'a is present in order to prevent slippage with the shoot root 6a. However, a protrusion such as a timing belt having a protrusion 7'b also formed on the drive surface (FIG. According to 9) (the driving roller also needs to correspond to this), the elastic belt 7 ′ itself does not slip and the pinching posture is stabilized. When the elastic belt 7 'slides, the positional relationship with the other party changes, and the stem root 6
This is because a may be rotated inside and the pinching posture may be deteriorated.

As described above, the rubbing guide 20 has a shape in which the upper portion is convexly curved. In this case, it is preferable that the rubbing guide 20 has a relatively large radius and is wide. The material is not limited, but a material having a smooth surface is suitable. With the transport, the bottom of the head portion 6b
Since it is strongly pressed against the upper surface of the rubbing guide 20, the head portion 6b
This is because there is little damage, the transport resistance is small, and the posture is stable.

Furthermore, since the speed of the lower rhizome pulling device 4 is set to be higher than the speed of the rhizome pulling and conveying device 3,
When the rhizome 6a is applied to the cutting device 25 due to this speed difference, the oblique one is straightened, the cutting is made at right angles to the root 6a, and the cut surface becomes clean (the disc cutter 26). Is parallel to the rotation surface of the lower rhizome extraction device 4), thereby preventing cutting unnecessarily high points to lower the yield.

When the root portion 6a is cut by the cutting device 25, the root portion 6a is pinched by the root extraction device 3 and the lower root extraction device 4, and the head portion 6b is pinched by the head transport device 5. It is in a state of being done, and the posture is very stable. Therefore, it does not move at the time of cutting, and can stably cut a fixed portion. The stem root portion 6a and the demon leaf 6c cut in this way are discarded as it is,
Only the head portion 6b is nipped by the belt 28 of the head transport device 5 and is conveyed rearward.

FIG. 6 is a cross-sectional view of the head transporting device 5 showing the state of transport of the head 6b. At this time, two moving supports (round belts) 35 hit the bottom of the head 6b and firmly attach it. (Because the rail 38 does not hang down itself), it does not drop or lose its posture, and is therefore smoothly transported to the end. Since the head portion 6b is shipped as it is, care must be taken not to damage the head portion. However, since the round belt 35 moves at the same speed as the belt 28 of the head transfer device 5, the head portion 6b No slippage occurs between the head and the head portion 6b. The head portion 6b transported by the head transport device 5 is moved vertically by the vertical transport device 4
0 and sent to the side of the airframe 2 by the horizontal transport device 41,
It is stored in a container.

The transport power is strong,
Its posture also stabilizes. Further, in addition to carrying the stem root portion in a pinched state, since the guide is supported and guided in two stages up and down while rubbing the bottom of the bulb portion with a rubbing guide, the carrying posture is stabilized by suppressing shaking and the like.

In addition, at the rear of the above-described root and root pulling and conveying device,
By providing a cutting device that cuts the top of the bulb portion rubbed by the rubbing guide together with the stem root, scratches generated when the rubbing guide is rubbed remain.

In addition to setting the inclination of the lower root extraction device to be gentler than the inclination of the root extraction device, if the pinching force is set to be stronger than the clamping force of the root extraction device, the root As the is transported backward, the stem root slides down from the stem root pulling and conveying device, and the height of the head portion becomes constant. Therefore, the height is unified even when cutting is performed later. At this time, if the above-mentioned rubbing guide is provided, it is also possible to rub the bottom of the head portion and make it necessary for the guide, and strictly set the working height of the shoot root extraction and transfer device. Even if it is not necessary, the cutting height of the head portion can be kept constant, so that the operation is easy.

Further, the speed of the lower root extraction device is set higher than the speed of the root extraction device, and the posture of the root changes as the root is transported backward. If it is close to a right angle, the inclination of the root of the shoot to the transport plane is corrected, sufficient pinching force and resistance to cutting are obtained, stabilizing the cutting, and making the cut surface of high commercial value It can be beautiful.
