The course correction during harvesting is performed by swinging the steering handle left and right. Although it is excellent in that it can make a fine course correction during harvesting and that small turning is effective, it is a countermeasure to avoid running the running wheel so as to step on the unharvested position of vegetables in the field running at the time of harvesting Has not been actively adopted. For this reason, unharvested vegetables may be damaged by being stepped on by the traveling wheels.

(B) There is a possibility that the leaves of the harvested vegetables may fall on the walking area of the operator who operates the control handle, thereby hindering the walking of the operator. During harvesting in the subsequent process, the traveling wheels pass through, and the running stability of the aircraft is impaired, and there is a possibility that an accurate harvesting process cannot be performed. (E) Further, since there is no mechanism for accommodating the roots in the container during harvesting without relying on human power, the burden on the operator during the harvesting operation is increased.

That is, the traveling device is a crawler type, the holding and conveying means for vegetables is bent in the middle of the conveying direction, one end side is a front and rear portion, and the other end is a horizontal portion, and the conveying end of the horizontal portion is Since it has reached the side of the aircraft on the side where the field has been harvested, a large traveling drive force is obtained, and the leaves falling on the ground will not hinder the walking of the operator who operates the aircraft. In addition, the traveling device does not step on the leaves on the ground during harvesting in the subsequent process, but the structure of the traveling device becomes complicated and heavy, and the mobility of the aircraft does not work effectively. Inferior to

Further, the following problems are common to JP-A-60-224409 and JP-A-60-224409. (A) When the traveling device falls into the furrow groove, the fuselage inclines greatly, which makes it difficult to control the aircraft,
There is a risk that stable harvest processing may be impaired. (B) When unharvested vegetables remain in the row of vegetables being harvested, the traveling device may step on the unharvested vegetables and damage the unharvested vegetables during harvesting of the row. (E) The drooping root at the tip of the root of the harvested vegetables cannot be mechanically removed during harvesting, and the soil attached to the harvested root may be carried into the container together with the root.

Reference numeral 4 indicates that most of the leaf part a of the ginseng w is held together by the left and right endless belts 7a and 7b at the transport start end.

Thereafter, the nipping and conveying means 14 conveys the nipped leaf portion a obliquely rearward and upward at the front-rearward portion c1 at substantially the same speed as the machine body by the orbital movement of the pair of endless bands 7a and 7b. With this, the leaf part w conveyed is pulled upward by the pair of endless bands 7a and 7b.
On the other hand, while the moat-raising blade 29 is vibrated around the fulcrum shaft 28 by the power of the engine 4, it travels in the soil below the ginseng w which has reached the vicinity of the transport start end of the nipping transport means 14, and around the action portion 29 a. Crush the soil and make it soft and soft. Therefore, the ginseng w which is conveyed obliquely upward the leaf part a by the pinching conveyance means 14
Is easily pulled out of the soil by the tensile force acting on the leaf a sandwiched between the endless bands 7a, 7b.

The root portion b thus pulled out is further continuously and rearwardly conveyed by the holding and conveying means 14, and passes between a pair of left and right surface guides g1 and g1, and the root tip root cutting means 35 and the root dropping means 36. Reaches the processing point. Here, the root dropping means 36 is a pair of left and right rotating brushes 4.
4a, 44b, the root b is rotated by these rotating brushes 44a, 44b.
The soil attached to the root portion b is separated and dropped by rubbing between the b and the brush bristles on the surface. Further, the root tip root cutting means 35 includes a pair of left and right disk rotating blades 43.
In steps a and 43b, the thin root hanging down from the root tip is cut off and dropped. The root b, which has been cut by the disk rotating blades 43a, 43b, is the left and right rotating brushes 44a, 4b.
4b, the standing posture is stabilized, whereby the cutting of the hanging root e by the disk rotary blades 43a, 43b is performed smoothly and reliably.

Thereafter, the root b reaches the root shoulder aligning means 37. The root shoulder alignment means 37 receives the root b between the left and right guide rods 45, 45. At the front part of the guide rods 45, 45, the shoulder of the root b does not contact the guide rods 45, 45, but the nipping and conveying means 14 As the transport proceeds, the shoulders approach the guide rods 45, 45 and eventually abut against the guide rods 45, 45. Thereafter, the root b is transported rearward by the nipping transport means 14. During this transport, the root b is guided by the guide rods 45, 4
The upward displacement is regulated by 5, and the shoulder is moved rearward in a state of contacting the lower surfaces of the guide rods 45, 45. Therefore, the roots b which are successively pulled out from the ground and reach the root shoulder aligning means 37 can align the positions of the shoulders to the same position and height. By the way, after the shoulder of the root b comes into contact with the guide rods 45, 45, the leaf a is tensioned by the upward pulling force applied by the nipping and transporting means 14, and the leaf supporting and transporting means Numeral 38 nips the original portion of the tensioned leaf portion a with left and right holding means (endless belts 46, 46) and synchronizes with the conveyance speed of the holding and conveying means 14 to convey the rearward along the guide rods 45, 45. .

When the root b reaches the rear end of the guide rods 45, 45, the root cutting means 39 causes the left and right disk rotary blades 48 to rotate.
The upper end of the root b is cut horizontally at positions near the lower surfaces of the guide rods 45 at 45a and 48b. During this cutting, the leaf part a is firmly supported by the leaf part supporting and conveying means 38,
The posture of the root b to be cut is stabilized,
Therefore, the root b is cut smoothly and accurately at a position immediately adjacent to the shoulder. The root b cut in this way falls apart from the leaf a and is received by the root guide means 40. The root guide means 40 slides the root b into the container 49 by gravity due to its slope. Thus, the roots b are sequentially accumulated in the container 49. At this time, the roots do not receive a large impact and are not damaged.

On the other hand, the leaves a after the root b has been separated by the root cutting means 39 are released from the support and transport by the leaf support and transport means 38 as soon as possible. Is the horizontal portion c of the holding and conveying means 14
After being nipped and conveyed to the field harvested side by 2 and reaching above the right running wheel 8b, it is released and falls on the ground. The fallen leaf portion a lands on the right side of the operator who operates the steering handle 9 behind the traveling wheel 8b, and therefore does not hinder the traveling of the machine body or the walking of the operator. Further, since the container means 16 is also displaced to the left side of the body, it does not hinder the walking of the operator.

During the harvesting operation, the right running wheel 8b may fall into the groove m between the ridges as shown by the imaginary line k in FIG. Activate the driving means 10 to operate the chain case 6b.
Is swung downward around the specific horizontal line s so that the right traveling wheel 8b is lowered with respect to the body frame 3.
Thereby, the lateral inclination of the machine body is eliminated, and the harvesting work becomes possible.

In this embodiment, the position for pulling out the vegetables and the like d of the holding and conveying means 14 is located on the right outside of the machine body with respect to the left running wheel 8a. Even when a part of the ginseng w fails to be harvested, it is possible to avoid a situation in which the traveling wheel 8a steps on and damages the ginseng w that is not harvested.

Further, the fact that the right driving wheel 8b, which is far from the drawing portion d for vegetables and the like, can be moved up and down by the power drive device 10 means that the density of the components around the right driving wheel 8b can be reduced by the left side. It is easy to secure a space for installing the power drive device 10 by making it smaller than that around the traveling wheel 8a, and to reduce the load acting on the right traveling wheel 8b by reducing the load. The structure can be easily reduced in weight.

The above embodiment can be modified as follows. In other words, the running wheel 8b is made lighter by making the tire width significantly smaller (for example, about half) than the left running wheel 8a. In the above embodiment, the right traveling wheel 8b is shifted from the left traveling wheel 8 based on the arrangement of the components of the entire body.
Since the weight of the traveling wheel 8a is smaller than that of the traveling wheel 8a, shortage of the strength can be avoided even if the traveling wheel 8a is significantly reduced in weight.

In the above-described embodiment, the extraction portion d for vegetables and the like is located on the left side of the fuselage with respect to the left traveling wheel 8a.
Instead of this, the extraction part d for vegetables etc. is connected to the right traveling wheel 8b.
The respective components may be arranged symmetrically to that of the above-described embodiment, such as being located on the outside of the right side of the fuselage, and may be of the opposite type.

Further, the vertical position of the right traveling wheel is changed and adjusted by a human-powered operation device instead of being changed and adjusted by a power drive device. It can also protrude further to the right than the wheels.

Therefore, harvesting on high ridges can be performed without trouble by avoiding excessive lateral inclination.

According to the fifth aspect of the present invention, the pulling-out portion of the vegetables or the like of the nipping and conveying means is located on the right or left side of the body outside the body with respect to the position between the left and right traveling wheels. Since the vertical position of the traveling wheel on the side remote from the vegetable or the like extraction portion can be changed and adjusted independently of the traveling wheel on the other side, the harvester of the present invention also has the same utility as that described in claim 1. By moving the traveling wheel farther from the drawer such as vegetables existing on the side of the fuselage up and down, the displacement of the vertical height of the drawer such as vegetables can be reduced and the furrow groove etc. can be obtained. Therefore, it is possible to eliminate the lateral inclination of the airframe caused by the above, and therefore, it is possible to harvest without difficulty even in a high ridge. Further, since a large distance can be secured between the traveling wheel and the nipping / conveying means whose vertical position is changed and adjusted, it is possible to easily realize interference between the traveling wheels and the vertical position. A space for mounting the traveling wheel change adjustment mechanism can be easily formed.

According to the sixth aspect of the present invention, since the running wheels farther from the drawing portion for vegetables and the like have a lighter structure than that of the other, the entire body can be reduced in weight. At this time, the load acting on the wheel can be made smaller than the load acting on the other traveling wheel, so that insufficient strength of the wheel can be prevented.

According to the seventh aspect of the present invention, similarly to the first aspect, the traveling mechanism has a simple structure and a light weight, so that the mobility as a harvester can be improved.
Also, during harvesting, the root tip cutting means can cut off fine roots hanging from the root tip, and the root shoulder aligning means optimizes the vertical height of the root, and the root cutting means cuts the upper end of the root. can do. As a result, at the time of sampling and harvesting in the field, it is possible to obtain a root portion in which the tip root and leaves are mechanically cut off.
