[0003]

In the above-mentioned root vegetable harvesting machine, in order to align the cutting position of the root vegetable toward the leaf cutting device, a position aligning / conveying mechanism having a roller conveyor structure is provided. The root movement is allowed to move up, so that the root vegetables rise as they are conveyed rearward, and finally, the root vegetables are brought into a contact conveyance state in which the root vegetables contact the rollers. However, because of adopting a spring structure that presses the left and right rollers together to sandwich the foliage, the rollers and the chain link that supports them are:
A relatively large gap is formed between adjacent rollers in the conveying direction in a rotating portion of the starting end sprocket, which is separated in the rotation plane direction of the chain, and the foliage may be caught in the gap. Then, the sliding movement of the leaf stem is performed while rubbing against the support member of the roller, and the resistance causes the contact conveyance state not to be obtained or the leaf stem portion to be cut off during conveyance. An object of the present invention is to avoid the above-mentioned inconvenience as much as possible by devising the structure of the alignment conveyance mechanism.

[0004]

In order to achieve the above object, according to the present invention, a leaf portion of a root vegetable is sandwiched between a pair of left and right front endless rotating belts which are driven to face each other while being inclined rearward and upward. And a pair of left and right rear endless rotating belts and a pair of left and right alignment transport mechanisms disposed below the pulling unit for pulling the root vegetables upward while pulling the root vegetables from the ground. And a transport device for transporting the root vegetables sent from the pull-out portion rearward by nipping and transporting the upper portion of the leaf portion by driving the pair of rear endless rotating bands while guiding and guiding between the alignment transport mechanisms. Provided, respectively, the vertical interval between the pair of rear endless rotating bands and the pair of alignment transport mechanisms,
The rear endless rotation band and the alignment conveyance mechanism are relatively arranged so that the rear endless rotation band becomes wider toward the lower side in the conveyance direction. The leaf holding force is set by a pair of rear endless rotating bands so that the downward movement from the end is allowed, and the alignment transport mechanism is wound endlessly over the front and rear wheels. A rotatable belt and a number of rotatable rollers supported in a protruding state by the endless rotatable band, and a root vegetable portion located between the rollers of the left and right alignment transport mechanism is nipped. The root vegetable harvest is set so that the left and right endless rotating belts are arranged relative to each other and the direction of the rotation axis of the rollers is set so that the vertical movement of the root vegetable leaf portion held by the alignment conveyance mechanism is allowed. Roller in one endless rotating band A state in which the roller gap portion and the other endless rotary Dotai of faces, and wherein configuration that the right and left of the endless rotating belt each other are relatively arranged in a root vegetable transport direction.

[0005]

In other words, the pinch position of the leaf stem is located in the gap between the rollers in one endless rotation band, but is located in the roller portion in the other endless rotation band. It becomes pinched by the rotating roller, which reduces the rate at which the sliding movement of the leaf stem is insufficient compared to the conventional case where both the left and right are pinched in the gap between the rollers. In addition, the inconvenience that the contact conveyance state cannot be obtained or the stem portion is cut off during the conveyance is suppressed.

[0001]

The present invention mainly relates to ginseng, radish,
The present invention relates to a harvester configured to pull out root vegetables such as onions from a field and perform a series of leaf cutting processes.

[0002]

2. Description of the Related Art A root crop harvesting machine is disclosed, for example, in Japanese Utility Model Application Laid-Open No. 61-12333 and Japanese Utility Model Application Laid-open No. 62-49917.
And Japanese Patent Application Laid-Open No. 64-16512 are known.

A harvesting machine disclosed in Japanese Utility Model Laid-Open Publication No. 61-12333 extracts and harvests root crops (carrots) from a field on one side of a self-propelled body that is operated by a boarding driver. With a harvesting unit, on the other side of the aircraft,
After the leaf cutting process, it is equipped with a collection unit that collects the root vegetable main body transported on the conveyor into a container, and the full container can be placed on the ground via a roller conveyor It has become.

A harvesting machine disclosed in Japanese Utility Model Laid-Open Publication No. Sho 62-49917 is a body towed and moved by a tractor or the like (not shown in the specification but a towing arm is shown, so that the towing type is shown). The harvesting unit digs and transports the root vegetables (onions) in the field, a roller conveyor for placing and transporting the harvested root vegetables, and drops the selected root vegetables into containers. And a collecting section for collecting and collecting, and during transport by the roller conveyor for sorting, foreign substances such as remaining foliage are dropped and separated from the gap between the rollers, and workers carrying defective products are selected and taken out and transported. Good products can be dropped into the container from the end of the conveyor and collected, and the gantry on which the container is placed can be lowered and tilted in accordance with the degree of root vegetable collection into the container. It is.

A harvester disclosed in Japanese Patent Application Laid-Open No. 64-16512 discloses a root crop planted in a field, which is picked up by a weeding body and guided by left and right nipping and conveying belts (20 in the publication). The root vegetables are pulled out of the field and suspended and transported by being held between the conveyor belts and transported rearward and upward, and the leaves of the root vegetables that are suspended and transported are adjusted by the left and right adjustment belts (33 in the publication). ), The height of the root vegetable body is regulated by an adjustment belt, the height position of the root vegetable body is aligned, and the leaves of the aligned root vegetable are cut with a cutter, and the root vegetable body is dropped and collected. It is configured as follows.

[0006]

Problems to be Solved by the Invention
The root crop harvesting machine disclosed in No. 33 is capable of collecting a root vegetable body that has been pulled and harvested and subjected to leaf cutting in a container, and the container can be placed in a field. Although it can be performed, the root vegetables can be collected relatively easily. However, no particular consideration is given to the leaf cutting process in the harvesting unit, and a highly accurate leaf cutting process is required. There was room for improvement in harvesting.

The harvesting machine disclosed in Japanese Utility Model Application Laid-Open No. 6249917 allows an auxiliary worker on a machine towed and moved to select only non-defective root vegetables and collect the containers, thereby enabling continuous harvesting. Although it can be performed efficiently, this harvester also does not take into consideration the point of increasing the accuracy of cutting leaves in the harvesting section, and there is a point to be improved in practical use as in the previous example. In addition, by changing the attitude of the container gantry that receives the root vegetable body released from the end of the conveyor, the root vegetable body can be collected without damaging it. The cylinder must be operated, and if this operation is performed by an operator, it is troublesome. Further, if the operation is automated, the apparatus becomes complicated and expensive. In addition, because of the towing mobile type, the entire harvester including the towing vehicle such as a tractor is long and large in the front and back, and can be introduced into large farms, but can be effectively used in relatively small farms. It was impossible.

The harvester disclosed in Japanese Patent Application Laid-Open No. 64-16512 can continuously and efficiently perform high-precision integrated operations from extraction of root vegetables, leaf cutting, and recovery of root vegetables themselves after leaf cutting. In order to do so, it was not yet sufficient in terms of practical use, including the overall configuration of the harvester, and there was a point that had to be improved.

In other words, the roots of the root crops often extend greatly in the horizontal direction or around the periphery, and the leaves that are greatly collapsed or the leaves that extend greatly in the horizontal direction are pinched and conveyed to the left and right. In some cases, the leaves may not be properly introduced between the belts, and a part of the leaves may leak from between the left and right nipping and conveying belts. As described above, when a part of the leaf part is disengaged from the holding between the conveyor belts and is conveyed while protruding below the conveyor belt, in the subsequent positioning process, the leaf part protruding downward is left and right for alignment. The root vegetables are easily pulled out from the adjustment belt and protrude below the adjustment belt. When the height is aligned on the lower surface, the protruding leaves are pinched between the root vegetable body and the adjustment belt, and the root vegetable body does not come close enough to the adjustment belt. The leaves protruding from the belt are left uncut without being cut, and the remaining leaves need to be manually cut off again, resulting in low cutting performance in the leaf cutting process.

[0010] In addition, root vegetables in the field, the amount of leaves,
Cultivation area, such as length, extent of leaf, degree of side
It varies according to growing conditions such as harvest time, variety, etc.
It is important to implement high-performance leaf cutting that can cope with this.

Further, in the step of pulling out the root vegetables in the field with the pinching and conveying belt, the root vegetable pulling reaction force acts on the starting end of the pinching and conveying belt. Changes every moment due to the soil hardness and the like, and the effect of this causes a change in the pinching height position of the leaf portion, which deteriorates the accuracy of the cutting position of the leaf portion.

Further, in the positioning device, the root vegetable body is received on the lower surface of the adjustment belt so that the height of the root vegetable body is uniform, the cutter is disposed above the adjustment belt, and the leaf is easily gripped. The leaves had been cut in the state. As a result, it is difficult to cut the leaves at certain positions,
In addition, the leaves will remain for a long time in the root vegetable body that has been subjected to leaf cutting, and there will be almost no uncut leaves of the leaves, that is,
If you want to obtain a root vegetable body whose leaves have been cut at the boundary between the leaves and the upper end of the root vegetable main body, it is necessary to manually cut off the leaves remaining on the root vegetable body that has been mechanically harvested and collected. The harvester will not be used effectively.

Further, since the harvested root vegetables are taken back to a processing facility and subjected to processing such as sorting and washing, a harvesting machine of this type is provided with a reasonable arrangement configuration to improve the harvesting function and processing accuracy. Not only is it expensive, but also how to efficiently recover the root vegetable main body is an important matter.
The harvester disclosed in Japanese Patent Publication No. 12 cannot take such a point into consideration.

The present invention has been made in view of such a point, and it is possible to efficiently perform a series of efficient cutting of leaves from the raising and transporting of root vegetables, and to enable appropriate lifting, sandwiching and transporting. The root vegetable body can be harvested with high accuracy of the cutting position and the leaf can be cut with almost no uncut leaves. It is a primary object of the present invention to provide a riding type root crop harvester that is compact and has excellent workability, which can select and efficiently collect the root crops.

[0015]

Means for Solving the Problems [Structure, operation and effect of the invention according to claim 1]

(Structure) The invention according to claim 1 is a soil breaker for loosening the soil near a root vegetable in a field, and an obliquely upward rearward from the vicinity of the ground in a posture in which a locking claw is projected forward. A leaf pulling device that moves and pulls up the leaf portion of the root vegetable in the field, a pinch pulling transport device that pinches the lifted leaf portion, lifts it, and transports it by hanging it upward and backward.
A position alignment device that introduces the leaf portion of the root vegetable to be conveyed suspended between the left and right guide portions and regulates the elevation of the root vegetable body by the guide portion while the root vegetable moves backward, and aligns the height thereof, A harvesting unit including a leaf clamping and conveying device that clamps the upper portion of the leaf portion above the guide portion and transports the leaf backward, and a cutter that cuts a leaf portion of the root vegetable clamped by the leaf clamping and conveying device. In addition to being placed on one side of the fuselage, a boarding operation unit is provided at the front of the other side of the fuselage, and a sorting conveyor for placing and transporting the root vegetables released from the harvesting unit is located along the outer edge of the fuselage. And a root vegetable main body collection unit for storing the root vegetable main body transported by the sorting conveyor in a container is provided at an outer edge of the fuselage at the rear of the fuselage, and the sorting conveyor is provided. , Rod-shaped transports arranged in parallel in the transport direction The container body is moved in the transport direction, and a separation gap is formed between the adjacent rod-shaped transport bodies, and the container holder provided in the root vegetable main body recovery unit is supported so that the rear end side can move up and down. To change the container's root vegetable receiving position and urge the rear end of the container tray upward to move the container receiving stage downward from the inclined position as the weight of the placed object increases. It is characterized by being constituted.

(Function) According to the above configuration, before the leaf portion of the root vegetable in the field is held by the nipping / lifting / conveying device, the root portion is subjected to the lifting action by the locking claw of the leaf portion pulling device.
Occurrence of leakage of the leaf portion at the starting end of the nipping and pulling transport device is reduced. As a result, after that, when the leaf portion of the root vegetable that is suspended and conveyed is introduced between the left and right guide portions that align the height, a part of the leaf portion is not introduced between the left and right guide portions. There is almost no possibility that the leaves protrude downward, the leaves are properly clamped by the nipping and pulling conveyance device, the leaves are properly guided between the left and right guides, and the leaves leaking from the left and right are pinched. Leafs that are caught at the introduction portion to the guide portion and that the leaf portion is caught between the root vegetable body and the left and right guide portions to prevent an obstacle in height alignment are prevented, or that the leaf portion protrudes below the guide portion. It is not necessary to cut off the uncut leaves again by hand after the machine harvest.

Further, even if the rooting condition of the root vegetables or the hardness of the soil at the place where the root vegetables are planted changes, when the roots are pulled up from the field with the leaves being pinched by the pinch pulling and conveying device, Since the crushed body loosens the soil near the root vegetable body, the root vegetable is less resistant and the pulling resistance of the root vegetable is relatively stable, and the root vegetable body remains in the field and only the leaves are cut off and transported Then, the leaves that have been torn and conveyed may cause an adverse effect on the height alignment in the subsequent process, or the leaves may slip down due to the lifting reaction force acting on the starting end of the nipping / lifting / transporting device, and The adverse effects of, for example, nipping and transporting the leading end side are reduced.

The height of the root vegetable main body is aligned by the left and right guide portions, and the root vegetable is supplied to the cutter while maintaining the aligned height by the leaf holding device, and the leaf portion is cut by the cutter. The root vegetables whose leaves have been cut and separated are conveyed by a sorting conveyor and sent to a container on a container receiving tray. At this time, if the storage capacity of the root vegetable main body in the container is small, the container tray is at a high position with the rear end swung up, and the container supported by this container tray has a small head and the root vegetable body is The root vegetable body is smoothly dropped and stored in the container without damage. Then, as the capacity of the container increases, the cradle gradually moves downward against the upward biasing force, and the posture of the container is also swung down, and the container is fully used for collection. Is performed.

Here, the sorting conveyor is configured such that bar-like carriers arranged in parallel in the carrying direction are moved in the carrying direction and a separating gap is formed between adjacent bar-like carriers. Therefore, foreign substances such as garbage and mud conveyed together with the root vegetable body fall through the separation gap during this conveyance. In addition, since the sorting conveyor is arranged near and along the outer edge of the machine, an auxiliary worker outside the machine that follows the walking does not have any damage or cracks from the conveyed material on the sorting conveyor. It is possible to sort out and remove non-defective products, poorly grown products, and garbage that did not fall from the gaps, and reduce the mixing of defective products and the like into containers.

Further, since the container receiving stand is arranged so as to be located at the outer edge of the machine body, an auxiliary worker outside the machine which walks and follows can easily drop the fully lowered container onto the field. In addition to being able to replace it with a new container, it is also possible to remove defective products and garbage that have entered the container while being sequentially loaded into the container, which is combined with sorting and removal on the sorting conveyor. As a result, mixing of defective products and the like into the container can be reduced.

(Effects) Therefore, according to the invention of claim 1, the function of the leaf pulling device prevents the leaf from being pinched and leaked at the starting end of the pulling and nipping and transporting, and also avoids the shredding of the leaf and the like. The height adjustment function of the root vegetable body by the subsequent left and right guides can be properly performed, the leaves can be reliably cut at a fixed position, and highly accurate leaf cutting can be performed, excellent in practicality Root crop harvester can be configured.

Also, a leaf that is greatly extended in the lateral direction or a leaf that has fallen is pulled upward from the front of the start end of the nipping / pulling-up conveyance device by a locking claw protruding forward to secure an upright posture. By removing the soil around the body of the root crop body, the pinch pulling and lifting device ensures that the leaves are properly pinched, the soft pull-out, and the transport in a stable posture. In this case, the cutting height is constant and the cut edges are neatly aligned, so that the continuous operation from the extraction of the root vegetables to the cutting of the leaves can be performed efficiently and with high precision.

Moreover, by adopting the leaf holding and conveying device, the leaves can be cut while maintaining the height aligned by the left and right guides, and the disadvantages such as the root vegetables being displaced downward are eliminated, and the stability is improved. It is possible to reliably cut the leaves at a certain position, and it is possible to cut the leaves at a position very close to the root vegetable main body, that is, to cut the leaves at the boundary between the leaves and the upper end of the root vegetable main body. Can be collected in a leaf-cut state with almost no uncut portion.

In addition, a sorting conveyor capable of dropping and sorting foreign substances and a root vegetable main body collecting section are rationally arranged on the outer edge of the machine body, so that a defective product and dust can be collected with less contamination. Can be performed, and sorting and container replacement by auxiliary workers outside the machine that follow walking can be performed.
A compact harvester that enables the driver to board and drive, and the recovery work can be performed by an outside assistant who walks and follows. In addition, it was possible to obtain a root crop harvester excellent in practicality, which can be harvested in a small field, and can be effectively used by being introduced into a small field.
