JP 2006-109783 A Japanese Patent Laid-Open No. 2006-320211

The crop harvesting machine described in Patent Documents 1 and 2 uses a pair of belts as endless belts, and the surface of the belt is smooth due to wear or the like when the crop leaves are sandwiched between the belts and pulled out from the field. If it becomes, it will become difficult to pull out the foliage of the crop from the field.
Then, the subject of this invention is providing the crop harvester provided with a pair of endless belts which are comparatively easy to pinch and remove the crop foliage from the field.

The above problem is solved by the following means.
According to the first aspect of the present invention, the stems and leaves of the crop grown in the field are sandwiched between a pair of conveying endless belts (28a, 28a) that are stretched between the pair of rotating bodies (28b, 28c) in the up-down direction and pulled out. In the crop harvesting machine provided with a holding and conveying device (28) for transferring, a cavity is provided inside the pair of conveying endless bands (28a, 28a), and the holding action side of the conveying endless bands (28a, 28a) is a rotating body. This is a crop harvester configured to be inclined upward from the contact surface side (see FIG. 8).

  The invention according to claim 2 is characterized in that a partition portion (28ae) having a posture in which the clamping action side is inclined upward from the rotating body contact surface side is provided inside the transport endless belt (28a, 28a). A crop harvester (see FIG. 9).

  The invention according to claim 3 is the crop harvesting machine according to claim 1 in which the protruding bodies (28af, 28af ') are provided inside the transport endless belts (28a, 28a) (see Fig. 10).

  According to the first aspect of the present invention, the pair of left and right transport endless bands (28a, 28a) is configured such that the nipping action side of the transport endless band (28a, 28a) having a hollow inside is inclined upward from the rotating body contact surface side. When 28a, 28a) pinches the foliage of the crop, the force of pulling the foliage of the crop is applied upward, so that even vegetables that grow on soil with hard soil and roots that are difficult to pull out are reliably pulled out. As a result, the work efficiency is improved, and the amount of unsettled crops is reduced, so that the worker can omit the work of extracting the unsettled crops after the harvesting operation, thereby reducing the labor of the workers.

  In addition, since the holding force of the transport endless belts (28a, 28a) is increased, the crops and leaves of the crop can be held with a strong force when transporting the extracted crop. Disturbance can be prevented, and work efficiency and crop quality can be improved.

  According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the holding action side is inclined upward from the rotating body contact surface side inside the transport endless belt (28a, 28a). By providing the partition member (28ae), it is possible to suppress the deflection between the upper and lower ends of the endless belt, so that the pulling force of the endless belt becomes stronger and the crop becomes easier to pull out, and the work efficiency is improved. By reducing the amount of crop leftover, the operator can omit the work of pulling out the leftover crop after the harvesting operation, thereby reducing the labor of the worker.

  In addition, since the endless belt clamping force becomes strong and crops can be prevented from falling, the crop foliage can be clamped with a strong force. As a result, it is possible to prevent crops from falling or the conveyance posture from being disturbed during conveyance, and to improve the work efficiency and the quality of the crops.

  According to the invention described in claim 3, in addition to the effect of the invention described in claim 1, by providing the projecting bodies (28af, 28af ′) inside the transport endless band (28a, 28a), the endless band When the load exceeds a certain level, the protrusions can suppress the deflection between the upper and lower ends of the endless belt, and the transport endless belts (28a, 28a) are recessed to leave the foliage and drop off the crop foliage. It is possible to cope with a variety of crops because the working efficiency and the quality of the crops are improved and the shape can be flexibly deformed according to the amount and shape of the foliage of the crops.

By extending and contracting 30, the front part of the left and right nipping and conveying belts 28 a and 28 a can be moved up and down together with the frame 40. Therefore, it is possible to easily adjust the top and bottom of the left and right nipping and conveying belts 28a and 28a according to the height variation of the ground and the state of the roots and leaves of the root vegetables to be held by the conveying action unit.

  The harvesting section 4 is also provided with a cutting device 31 that cuts the stems and leaves of the root vegetables to remove them from the root. The leaflet belts 32a and 32a that take the roots and leaves of the root vegetables and carry them horizontally in the middle of conveying the root vegetables with the left and right nipping and conveying belts 28a and 28a are connected to the end of the left and right nipping and conveying belts 28a and 28a. A pair of left and right is provided in a substantially horizontal posture below the portion. Further, when taking over and transporting the foliage belts 32a, 32a to the leaflet belts 32a, 32a, the root vegetables are engaged with the upper ends of the root parts to restrict the rise of the root vegetables, and the height of the root vegetables is set to the cutting device 31. Position alignment belts 33a and 33a for aligning with the set height are provided. A pair of left and right disc-shaped cutting blades 31a, 31a of the cutting device 31 are arranged behind the rear end portions of the alignment belts 33a, 33a, and the roots of the root vegetables that have been transported by the sandwiching transport belts 28a, 28a. Cut the base. The root parts of the cut root vegetables fall downward, and the foliage parts are conveyed to the rear of the machine body by the leaflet belts 32a and 32a and discharged from the conveyance part 6 on the rear side of the machine body.

A second conveyor 37 that transfers root vegetables in the same direction as the transfer direction, and a third conveyor 38 that extends from the conveyance end of the second conveyor 37 toward the rear of the machine and transfers root vegetables in the same direction. It is configured.

  The first conveyor 36 is constituted by a belt conveyor having a flat surface, and a residual leaf processing roller 39 whose lower side is driven and rotated in the same direction as the belt rotation direction on the upper surface of the belt on the lower transfer side is provided at the front end of the roller. The part side is provided in an inclined state in plan view so as to be inward of the machine body in the left-right direction compared to the rear end part side.

  In addition, a boarding unit 25 is provided for a worker who performs a replacement operation of the container 49 of the storage unit 5 and a sorting operation to remove defective products from the root vegetables conveyed by the third conveyor 38 to board the machine body. The boarding portion 25 is provided with a seat 27 so that an operator can easily board and work on the aircraft. In addition, a crop placement section 7 is provided on the outer side of the left and right direction body of the boarding section 25 so that a plurality of containers 49 can be placed in the front and rear rows from the front of the body to the rear of the body. The work can be efficiently performed by proceeding with the harvesting work while placing the container 49. The harvested product placing portion 7 is provided so as to be housed inside the machine body by being attached to the inside of the machine body so as to be rotatable and foldable.

  On the front side of the right and left nip-conveying belts 28a, 28a, a number of lugs 34a projecting in the front-rear direction are vertically raised, and are vertically raised along the case 34b to raise the foliage part. A plurality of protruding lugs 35a are laterally raised and circulated in the vertical direction along the case 35b to cause a horizontal raising device 35 for raising a foliage part, and a weeding tool 61 for weeding the foliage.

  The digging blade D is composed of an arm part 50 extending in the front-rear direction, a digging part 51 bent from the front part of the arm part 50 and extending downward, and a support plate 52 provided above the front part of the arm part 50. The arm portion 50 is configured to be attached to a swing arm 53 that swings in a vertical direction along a set locus. A pair of digging blades D are provided below the conveyance start end side of the left and right clamping conveyance belts 28a and 28a and on both the left and right sides of the conveyance start end portion S. And the lower part of the digging and raising part 51 that digs up the soil around the root part of the root vegetables is configured to enter a position inside the machine body from the upper part.

Since the conventional sandwiching and conveying belts 28a and 28a use sponge-like belts, they are not durable and need to be frequently replaced, resulting in high costs.
Therefore, as shown in the cross-sectional view of FIG. 3, each belt 28a is hollowed to give elasticity to the pair of belts 28a, 28a for pinching and pulling the leaves of vegetables (crops, foliage vegetables) grown in the field. It was in the shape. The cross-sectional shape of the hollow belt 28a is a substantially elliptical shape having a major axis in the up-and-down width direction, and the stalks and leaves of vegetables are opposed to the rotating body contact surface (hereinafter also referred to as a support surface) contacting the pulley 28b or 28c. When the vegetable stems and leaves are clamped, the central portion of the belt 28a can be reduced when the outer periphery of the side surface, which is the clamping surface side, is sandwiched between the arcs, so that the belt 28a is recessed. It is prevented from falling off the foliage and dropping off the foliage of the vegetables, and the work efficiency and the quality of the vegetables are improved.

  FIG. 4 shows a sectional view of the belt 28a. A thick portion 28aa is provided on the outer periphery of the side surface on the clamping surface side that sandwiches the foliage so as to face the support surface (rotating body contact surface) that contacts the pulley 28b or 28c. Since the support surface and the sandwiching surface can be prevented from being recessed in the middle of the foliage, it is possible to prevent the belt 28a from being dented away from the foliage and dropping off the foliage of the vegetables. And the quality of vegetables improves.

As shown in FIG. 5 which is a partial sectional view of the pulley 28b or 28c and a partial perspective view of the belts 28a and 28a, a cushion hole 28ab is provided in a direction along the wide plane inside the belt to make the belt 28a elastic. You can have it. Since the cushion hole 28ab is provided with an opening on the side surface in the belt thickness direction facing the crop that is grown in the field, there is no possibility of mud clogging the cushion hole 28ab.
In addition, by providing a beveled portion 28ac on the upper surface in the belt thickness direction, the upper surface of the belt is brought into close contact when the upper surface of the belt is crushed and deformed when the vegetable stems and leaves are sandwiched. Since it is possible to prevent the vegetables from falling during the transportation or from disturbing the transportation posture, the work efficiency and the quality of the vegetables can be improved.

  FIG. 6 shows a plan view of a part of the nipping / conveying belt 28a. The ribs forming the cushion holes 28ab provided on the side surface in the belt thickness direction are retreated with respect to the belt traveling direction (arrow A direction) as shown in FIG. By providing a corner, the cushioning property of the cushion hole 28ab is further improved compared to the case shown in FIG. In this way, the belt 28a can be deformed more flexibly according to the amount and shape of the stalks and leaves of the vegetables. Therefore, the stalks and leaves are held with a strong force. Since it can prevent, it can improve work efficiency and the quality of vegetables.

  As shown in FIG. 7, instead of the cushion hole 28ab of FIG. 6, the side surface in the belt thickness direction has a first receding angle θ1 with respect to the belt traveling direction (arrow A direction), And a plurality of fins 28ad having a second receding angle θ2 with respect to the belt traveling direction from the end of the straight portion.

  In this case, since the sandwiching and conveying belt 28a can be deformed more flexibly according to the amount and shape of the foliage of the vegetables, the foliage is pinched with a strong force. Since the conveyance posture can be prevented from being disturbed, there is an effect of improving work efficiency and vegetable quality.

  As in the embodiment shown in FIG. 8, the sandwiching and conveying belt 28a has a diamond-shaped cross section with a space inside, and resistance is applied to the drawing side (lower side). Since the pulling resistance when the cross section of the slab is deformed can be increased, it is possible to reliably pull out vegetables that are vegetated on a hard soil field or vegetables that have roots that are difficult to pull out, thereby improving work efficiency. In addition, since the amount of leftovers of vegetables is reduced, the operator can omit the work of pulling out the leftovers after the harvesting operation, thereby reducing the labor of the workers.

  If the conveyor belt 28a is mounted upside down, the force of pulling the stalks and leaves of the crop upwards will weaken, so even crops with stubble and foliage that are easy to tear can be pulled out of the field. As a result, the work efficiency is improved and the amount of crop leftover is reduced, so that the worker can omit the work of drawing out the leftover crop after the harvesting operation, thereby reducing the labor of the worker.

  Further, as shown in FIG. 9, the cross section having the internal space of the belt 28a shown in FIG. The plurality of rhombuses at this time have the same cross-sectional shape. That is, in the example shown in FIG. 9, the angle β formed by the support surface (rotary member contact surface) of the pulley 28b or 28c in the position where the central bridge 28ae faces the pinching surface of the belt 28a and the support surface of the belt 28a. The angles α formed with the adjacent surfaces are all the same (β = α), but the plurality of rhombuses do not have the same cross-sectional shape, and the angle formed between the central bridge 28ae and the support surface facing the foliage sandwiching surface of the belt 28a β may be larger than an angle α formed by the support surface of the belt 28a and a surface adjacent thereto (β> α).

  Further, as in the embodiment shown in FIG. 10, when the belt 28a has a substantially oval cross section with a space inside, the clamping surface of the belt 28a holds the crop in the central portion of the inner space on the pulley support surface side. By providing the ribs 28af that receive the dents that can be formed, the belts 28a can be prevented from being dented even a little, so that the belts 28a are prevented from being recessed and separated from the foliage, and the stems and leaves of the vegetables are prevented from being dropped. And the quality of vegetables improves.

  In FIG. 11, the belt 28 a is formed into a substantially oval cross section with a space inside, and the clamping surface (rotary member contact surface) of the belt 28 a is formed when the crop is clamped in the center of the internal space on the crop clamping surface side. An embodiment in which a rib 28af ′ for receiving a recess is provided, and the configuration as shown in FIG. 11 can prevent the belt 28a from being recessed as much as possible, while at the same time increasing the strength of the belt clamping surface. In addition, the belt 28a is prevented from being dented away from the foliage and dropping off the foliage of the vegetables, and the work efficiency and the quality of the crop are improved. Since the pinching force is unlikely to be reduced even if the wear is worn, it is prevented that the stems and leaves of the vegetable fall off, and the work efficiency and the quality of the vegetable are improved.

  As shown in the cross-sectional view of FIG. 12, a plurality of dent prevention ribs 28af 'and 28af may be provided in the inner space on the side of the product clamping surface or pulley support surface of the belt 28a having a substantially elliptical cross section. A plurality of the dent prevention ribs 28af and 28af 'may be provided on each of the pulley support surface side and the crop clamping surface side, and a large number may be provided on the clamping surface side from the pulley support surface side.

  With the above configuration, the belt 28a can be deformed more flexibly according to the amount and shape of the stalks and leaves of the vegetables. Can be prevented, so that work efficiency and vegetable quality can be improved.

  At this time, as shown in the cross-sectional view of FIG. 13, a relatively long rib 28af 'is provided in the inner space on the holding surface side so as to be inclined with respect to the pulley support surface side, and the holding portion provided with the inclined rib 28af' is provided. By providing a relatively short receiving rib 28af in the inner space on the pulley support surface side facing the surface, the belt clamping surface is directed downward by a pulling resistance when the crop is sandwiched between the belts 28a and 28a and pulled strongly from the field. It can be prevented from slipping. Further, since the receiving rib 28af is shorter than the inclined rib 28af ', it has a function of backing up the inclined rib 28af' when the receiving rib 28af is bent. Furthermore, if the receiving ribs 28af are also inclined, the belt 28a can be deformed more flexibly according to the amount and shape of the stalks and leaves of the vegetables. Since it is possible to prevent the vegetables from falling or the conveyance posture from being disturbed, the work efficiency and the quality of the vegetables can be improved.

  Further, as shown in the cross-sectional view of FIG. 14, by providing the inclined ribs 28af 'and 28af so as to overlap each other on both the clamping surface side and the pulley support surface side, the ribs 28af and 28af' can be deflected. It is possible to hold the stems and leaves of vegetables to be pulled out or sandwiched and transported with a certain clamping force, so that the extraction and sandwiching of the vegetables are performed reliably, improving work efficiency and working on the remaining vegetables. Since the work to be pulled out by the worker is omitted, the labor of the worker is reduced.

  The embodiment shown in the cross-sectional view of FIG. 15 is an example in which hollow ribs 28ag are provided inside the crop holding surface of the belt 28a having a substantially elliptical cross section, and the hollow ribs 28ag reduce the dents in the crop holding surface. Therefore, it is prevented that the belt 28a is dented and separated from the foliage, so that the foliage of the vegetables is not dropped off, and the work efficiency and the quality of the vegetables are improved.

  Further, as shown in the cross-sectional view of FIG. 16, a solid belt 28a having a substantially elliptical cross section is provided, and a plurality of hollow portions 28ab ′ in which the inside is partitioned by a plurality of partitions are provided to provide cushioning properties. Since the belt 28a can be deformed more flexibly according to the amount and shape of the vegetable foliage, the foliage is pinched with a strong force. Since it can be prevented from being disturbed, the work efficiency and the quality of vegetables can be improved.

  Further, in the embodiment shown in the cross-sectional view of FIG. 17, the rigidity on the clamping surface side is improved as compared with the prior art by providing more partitions for partitioning the hollow portion 28ab ″ on the crop clamping surface side than on the pulley support surface side. Therefore, even if the belt 28a is worn, the pinching force is unlikely to be lowered, so that the vegetable stems and leaves are prevented from falling off, and the work efficiency and the vegetable quality are improved.

  18 shows an example in which one or more dent prevention ribs 28af ′ are provided in the internal space of the pair of crop clamping surfaces of the belt 28a shown in FIG. By providing the pinching surfaces of the pair of belts 28a for pinching the crops at locations where the ribs 28af 'of the other pinching surfaces do not exist, the cushioning property is improved without interfering with each other. Since it can be deformed more flexibly depending on the shape and shape, the stems and leaves are pinched with a strong force, so it is possible to prevent the vegetables from falling or the posture of the transfer from being disturbed during the transfer. And the quality of vegetables can be improved.

  Further, as shown in the cross-sectional view of FIG. 19, a solid belt 28a having a substantially elliptical cross section is provided, and a plurality of hollow portions 28ab 'each of which is partitioned by a plurality of partition portions are provided. In the holding surfaces of the pair of belts 28a, 28a that hold the vines, it is possible to maintain the holding ability of the crops by providing them at locations where there is no partitioning portion between the other holding surfaces, so that the leaves are held with a strong force For this reason, it is possible to prevent the vegetables from falling or the conveyance posture from being disturbed during the conveyance, so that the work efficiency and the quality of the vegetables can be improved.

  FIG. 20 shows a side view of the neck alignment transfer device 33 provided with the alignment belt 33a, the tapping transfer device 42 provided with the tapping transfer belt 42a, and the leaf transfer device 32 provided with the leaf transfer belt 32a. A plan view of the device 33 and the leaf transfer device 32 is shown in FIG.

  The drive case 32d of the leaf portion transfer belt 32a is disposed on the inner side of the inner periphery of the leaf portion transfer belt 32a (width L1 of the leaf portion transfer belt 32a> width L2 of the drive case 32d). Also, mud and stalks and leaves are less likely to accumulate. Further, since the start end portion of the drive case 32d is arranged behind the front leaf portion transfer pulley 32b (length L in FIG. 20), mud hardly accumulates on the drive case 32d. It is possible to perform the work to remove the work in a short time, and the labor of the worker is reduced.

  Further, by supporting the pulleys 42b and 42c of the tapping transfer belt 42a from a plate 42d disposed above the belt 42a, mud, foliage and the like are prevented from entering the winding region of the belt 42a by the plate 42d. Can do. This makes it difficult for mud, foliage and the like to accumulate, so that the worker can perform the work of removing mud, foliage and the like in a short time, and the labor of the worker is reduced.

  Since the present invention is a machine capable of harvesting crops such as root vegetables by mechanical force, it is highly applicable to the industry as an agricultural machine that releases agricultural work from heavy labor.
