[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device for conveying a conveyed object obliquely upward, and a spherical vegetable harvesting machine for traveling in a field by traveling means to harvest spherical vegetables such as lettuce and cabbage.

[0002]

2. Description of the Related Art A conventional spherical vegetable harvester is shown in FIGS.
, And the spherical vegetable harvester will be described. A spherical vegetable harvesting machine 10 (hereinafter, simply referred to as a harvesting machine) shown here has a driver's seat 1 on an upper part of a crawler 12 for traveling in a field.
4 and the harvesting device 15 are provided. The harvesting device 15 is provided on the left side of the driver's seat 14 in the front-rear direction. A container 16 for storing the harvested spherical vegetables is arranged on the rear side of the harvesting device 15.

On the front side of the harvesting device 15, the crawler 12
The conveyor belt 17 is provided so as to project further forward than the conveyor belt 17, and two disks 18, 18 for taking in spherical vegetables are provided at the tip of the belt conveyor 17. The belt conveyor 17 is composed of an upper belt conveyor 17a and a lower belt conveyor 17b so that the harvested spherical vegetables can be sandwiched between the upper and lower parts and conveyed. Each disk 18 rotates in a direction in which spherical vegetables are taken into the belt conveyor 17 side by a driving means such as a motor on both sides of the tip of the belt conveyor 17. By providing the rotating disk 18 in this way, it is possible to raise the spherical vegetables that have fallen or tilted and to surely harvest them. Also, the disks 18, 18
A cutter (not shown) is provided on the rear side of the disk to cut the roots of the spherical vegetables taken in by the disks 18, 18.

The spherical vegetables whose roots have been cut are shaped so as to be sandwiched between the upper belt conveyor 17a and the lower belt conveyor 17b, and are conveyed backward. Next to the transport device 15 on the crawler 12, another operator different from the driver is on board, and confirms the cutting portion of the spherical vegetables transported to the transport device 15 and removes outer leaves. After the work is performed and the spherical vegetables are prepared so that they can be shipped, the spherical vegetables are stored in the container 16.

On the rear end side of the belt conveyor 17,
A cylinder 19 is provided so that the belt conveyor 17 and a cutter or disk 18 provided on the belt conveyor 17 move up and down with respect to the crawler 12. When the cylinder 19 operates, the belt conveyor 17 rotates about the rotation shaft 9, and the disk 18 and the cutter provided at the tip of the belt conveyor 17 move up and down with respect to the ground. That is, the ground in the field has unevenness, and the driver operates the cylinder 19 so that the positions of the cutter and the disk 18 follow the unevenness of the ground so that the spherical vegetables can be reliably cut at the root.

[0006]

In the harvester described above, the spherical vegetables cut by the cutter are sandwiched between the upper belt conveyor and the lower belt conveyor and conveyed to the processing section. In this way, with a conveyor device that sandwiches the top and bottom of a spherical vegetable with a belt conveyor, if you try to raise it at a steep angle and convey it, it will be easier for the spherical vegetable such as lettuce to roll downward. , I had to increase the pinching force between the upper and lower conveyors. However, if they are sandwiched too strongly, the spherical vegetables themselves will be damaged.

On the other hand, as shown in FIG. 12, there has been considered a device in which a left and right side surfaces of a spherical vegetable are sandwiched between belt conveyors as a conveying device. In this carrying device 1, a front pulley 5 for taking in the spherical vegetables 4 is provided upright in a direction perpendicular to the belt carrying direction. That is, in such a conveying device 1, the front pulley 5 is provided to be inclined forward with respect to the traveling direction of the harvester (direction of arrow F), and when the spherical vegetables 4 contact the belt 6. Since the belt 6 contacts only a part of the spherical vegetables 4, the driving force of the belt 6 is not transmitted to the spherical vegetables 4 and the belt 6 only rotates without conveying the spherical vegetables 4. There is a problem. Further, in the transport device of FIG. 12, since the upward force is suddenly applied when the spherical vegetables come into contact with the front pulley, it is difficult for the spherical vegetables to enter between the belts, and the spherical vegetables cannot be reliably transported. ing.

If the front pulley of such a belt conveyor is set upright in the vertical direction, the spherical vegetables come into contact with almost the entire surface of the end portion of the belt, so that the driving force is reliably transmitted, which is preferable. However, if the front pulley is oriented in the vertical direction, the inclination angle of the entire belt conveyor becomes smaller, so the inclination becomes gentle to raise it to the processing section, the transport distance becomes longer, and the entire harvester becomes large. There is a problem such as becoming In addition, even if an attempt is made to combine a belt conveyor with a gentle slope and a belt conveyor that goes almost vertically to the processing unit (not shown), the spherical vegetables are transferred between the belt conveyors and the spherical vegetables are transferred. The part of the belt that contacts the spherical vegetables will be different. As described above, if there are a number of contact points of the belt on the spherical vegetables, there is a problem that the spherical vegetables are easily damaged.

[0009] The present invention is made to solve the above problems, and an object, as well as transmitted to reliably conveyed the driving force, reliably and easily enters the spherical shaped vegetables between belt conveyors An object of the present invention is to provide a spherical vegetable harvester that can be transported and can be downsized with a compact structure by shortening the transportation distance.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described in more detail with reference to the drawings. First, the overall configuration of the spherical vegetable harvester will be described based on the perspective view of the entire spherical vegetable harvester of the present invention shown in FIG. The spherical vegetable harvester 30 according to the present invention enables spherical vegetables 22 such as lettuce and cabbage planted in the ridges 20 to be continuously harvested along the row of the ridges 20 in the field. Reference numeral 32 is a traveling means such as a tractor. The traveling means 32 is not limited to a tractor as long as it can travel in a field, and may be, for example, a vehicle with a crawler.

An attachment arm 35 is attached and fixed to the rear of the traveling means 32 for attaching a spherical vegetable harvester body (hereinafter, simply referred to as a harvester body) 34.
The mounting arm 35 is mounted so as to extend in the lateral direction of the traveling vehicle 32 (direction orthogonal to the traveling direction indicated by the arrow). 31 is a mounting vehicle 35 from the mounting arm 35
It is a mounting member that extends toward.

The harvester main body 34 includes a frame 37 having a cutting blade 40, a guide disk 38, a conveying device 36 and the like.
Is provided on the front side of the mounting arm 35 so as to be swingable in the left-right direction with respect to the traveling means 32. The detailed configuration and operation of the harvester main body 34 will be described later.
The worker 2 is arranged on the rear side of the harvester main body 34. The worker 2 confirms the cut end of the spherical vegetable that has been harvested and has come out from the transport path 71 of the transport device 36 of the harvester main body 34, and removes the outer leaf if the outer leaf is attached,
After this, it is transferred to the spherical vegetable processing device 39 provided on the rear side of the mounting arm 35.

The spherical vegetable processing device 39 has a conveyor 43 rotating in a horizontal plane, and processes the cut end of the root of the harvested spherical vegetables. That is, when the spherical vegetables are lettuce, it is necessary to wash away the juice (milk) from the cut end to cause discoloration of the vegetables. The spherical vegetable processing device 39 is provided with a shower 21 to wash away the juice from the cut end. The worker 3 is also arranged in the spherical vegetable processing device 39. Worker 3
The shower 21 uses the shower 21 to wash away the cut edges and the like before packaging the spherical vegetables, and packages the washed vegetables after packaging. The processing unit in the claims refers to the entire place where the worker 2 and the worker 3 are arranged. The spherical vegetable processing device is not limited to the conveyor as shown in the drawing, and a plurality of storage containers or the like having a size capable of storing spherical vegetables can be connected and rotated on a horizontal plane. It may be a thing.

2 to 6, the part of the harvester main body 34 shown in FIG. 1 excluding the carrying device 36 will be described in more detail. 2 to 6, the traveling vehicle 32 and the transfer device 36 are omitted. First, the frame 37 provided on the mounting arm 35 so as to be swingable in the left-right direction will be described. 41 is
It is a U-shaped rear frame member that is provided on the rear side and has an upper opening. The rear frame member 41 includes two vertical members 41a and 41b which are vertically provided and the two vertical members 41.
a, 41b and a lower member 41c which is hung on the lower part. A rotating shaft 42 that projects downward is provided in the center of the lower surface of the lower member 41c. The rotating shaft 42 is inserted into a bearing 44 provided on the mounting arm 35 so as to be freely rotatable. By freely rotating the rotating shaft 42 with respect to the mounting arm 35, the frame 37 can swing in the left-right direction with respect to the traveling means 32 (direction of arrow A in FIG. 2).

Further, an upper link 45 and a lower link 46, which extend toward the front side and are rotatable in the vertical direction, are provided on the upper and lower portions of the vertical members 41a and 41b, respectively.
The front side ends of the upper link 45 and the lower link 46 are attached to the front frame member 48 so as to be vertically rotatable. Therefore, the upper link 45 and the lower link 46 are parallel links on the left and right sides, respectively. Front frame material 48
Are vertical members 50a, 50b each formed in a U-shape with an opening at the bottom and provided on each of the left and right sides, a horizontal member 51a connecting the vertical members 50a on the front side, and a vertical member on the rear side. Material 5
It is composed of a horizontal member 51b connecting the 0b members.
Further, the lower members of the front vertical member 50a and the rear vertical member 50b are connected by connecting members 52a and 52b, and the front vertical member 50a and the connecting members 52a and 52b are
The front vertical member 50a is pivotally mounted so as to be rotatable in the front-rear direction about the rotary shaft 53.

A cutting blade 40 is attached to the lower end of the vertical member 50b on the rear side. Cutting blade 4
0 is formed in an arc shape and has a sharp tip 40a.
Is provided so as to face rearward with respect to the traveling direction.
In this way, since the sharpening tip 40a of the cutting blade 40 is directed rearward and attached and fixed at the rear end, the residue such as scraps when the spherical vegetables are cut is less attached to the blade. Also, the sharpness when cutting is improved.

The cutting blade 40 can be moved up and down by rotating the handle 54. That is, the vertical member 5 on the rear side
0b is formed in a tubular shape, and the inner wall surface is threaded. A mandrel 56, which is a threaded rod that can be screwed into the thread groove and has the cutting blade 40 fixed to the lower end, is inserted into the vertical member 50b. Therefore, by rotating the handle 54 provided at the upper end of the mandrel 56, the mandrel 56 can be moved up and down to adjust the position of the cutting blade 40 in the up-down direction. In this way, the cutting blade 40
By arranging the upper and lower positions of the adjustable, the cutting blade 40 can be surely arranged in accordance with the position of the root of the spherical vegetable 22, the root can be surely harvested, and the blade of the spherical vegetable has a blade. It is possible to prevent scratches.

The guide discs 38, 38 are freely rotatable discs, and the rotary shaft 60 is provided at the lower end of the front vertical member 50a in the vertical direction (it may be vertical or not vertical). ) Is attached to face. That is, the guide disks 38 are provided on the front side of the cutting blade 40, and are provided on both the left and right sides facing each other with the spherical vegetables immediately before being harvested by the cutting blade 40 sandwiched therebetween. In addition, the space between the two guide disks 38 is determined by the cross member 5.
It can be adjusted by adjusting the distance between the vertical members 50a with respect to 1a. The intervals of the vertical members 50a can be adjusted by sliding the vertical members 50a along the axial direction of the horizontal members 51a.

This guide disk 38 is provided to orient the frame 37 in the direction in which the planted spherical vegetables are present. That is, even if the row of spherical vegetables is disturbed, if either one of the guide disks 38 comes into contact with the outer circumference of the spherical vegetables at a position deviated from that row, the guide disk 38 is removed from the spherical vegetables. By receiving more force, the rotating shaft 42 that rotates freely is moved so that the entire frame 37 faces the guide disk 38 side. Therefore, even if the row of spherical vegetables is disturbed, it is possible to satisfactorily harvest without directing the traveling means 32 to the disturbed direction each time. The driver will be able to harvest reliably by driving almost straight along the row of globular vegetables. This is an action that can be exhibited in combination with the configuration in which the entire frame 37 is swingably provided in the left-right direction.

Further, the guide disk 38 can be tilted in the front-rear direction (arrow B in FIG. 5). That is, by making the vertical member 50a on the front side rotatable about the rotating shaft 53 of the connecting members 52a and 52b, the guide disk 38 has a rotating shaft in a direction orthogonal to the traveling direction. It inclines. This guide disk 3
The tilting movement of 8 is possible by rotating the handle 62. The handle 62 is provided at the front end of the screw rod 63. The threaded rod 63 has an intermediate portion screwed into a female screw portion 64 provided at the upper end of the horizontal member 51a on the front side, and a tip end thereof fixed to a fixing portion 65 provided at the upper end of the horizontal member 51b on the rear side. It is fixed.

That is, when the handle 62 is rotated, the female thread portion 64 moves back and forth along the screw rod 63, whereby the front vertical member 50a is rotated around the rotary shaft 53 with respect to the rear vertical member 50b. The guide disk 38 is rotated, which allows the guide disk 38 to be tilted. By inclining the guide disc 38 in the front-rear direction, the guide disc 38 is guided when the spherical vegetables are guided to the cutting blade 40.
You can insert it into the lower part of the globular vegetable and guide it securely without damaging it. Further, the guide disk 38 may be inclined so that the front side is slightly raised. As a result, even if the ground surface is uneven, the guide disk 38 can be prevented from diving on the ground.

Further, the frame 37 extends between the lower side of the vertical member 50b on the rear side of the front frame member 48 and the upper side of the vertical members 41a and 41b of the rear frame member 41.
A spring 66 is provided as an urging member that constantly urges the front frame member 48 side, which is the front side, to pull up. In this way, since the spring 66 is provided so as to pull up the front side of the frame 37, the upper link 45 and the lower link 46 which are rotatable on the rear side are lowered on the front side by the weight of the frame 37 itself. I try not to touch or dive on the ground. That is,
Even when the ground surface has unevenness, the front side of the frame 37 moves up and down in accordance with the unevenness, and the cutting blade 40 and the guide disk 38 follow the ground. As a result, the cutting blade 40 and the guide disc 38
Since the and can be reliably positioned at the root of the spherical vegetable, the vegetables can be surely harvested without being wasted without damaging the vegetables.

Next, a conveying device for conveying the spherical vegetables cut by the cutting blade 40 to the container will be described. FIG. 6 is a perspective view of the carrying device, and FIGS. 7 and 8 are views showing the framework of the carrying device. The transport device 36 is configured such that a transport path 71 for transporting spherical vegetables is provided with two conical belt conveyors 79, 79 sandwiched between the left and right sides. The belt 70 forming the belt conveyor 79 is fixed inside the frame 37. Further, the fixed shaft 72 located at the center of the cone is provided so as to form an angle of approximately 45 degrees with the horizontal plane. That is, the apex of the cone also faces 45 degrees with respect to the horizontal plane. Each belt 70 has its apex rotatably provided with respect to the fixed shaft 72, and rotates about the fixed shaft 72.

The shape of the belt 70 will be further described. Each belt 70 has a shape like an umbrella shape, that is, a cone formed so as to spread from one end side to the other end side of the fixed shaft 72 is crushed as if a force is applied from the lateral direction. It looks almost like a cylinder when viewed from the front. In other words, each belt 70 has a shape in which a cone (umbrella shape) is crushed so that planes parallel to each other are formed along the front-rear direction. The parallel surfaces of the two belts 70 along the front-rear direction face each other to form the conveyance path 71.

Each belt 70 is formed in a fan shape obtained by dividing a circle into quarters when viewed from the side. 74 is belt 7
0 is an upper rotary shaft portion located in the upper part of 0 and extending in the horizontal direction, and 76 is a front rotary shaft portion located in the front surface of the front side of the belt 70 and extending in the vertical direction. The belt 70 rotates so as to be folded back by the upper and front rotary shaft portions 74 and 76. The fixed shaft 72 is located at the center of such belt driving, and the fixed shaft 72 itself is provided without rotating.

The fixed shaft 72 is fixed so as to project upward from the upper surface of an inclined frame 78 which is a skeleton constituting the conveying device 36. The inclined frame 78 is for each belt 7
It is provided so as to be located inside the open lower side of 0. Explaining the inclined frame 78, the rear end portions of the inclined frames 78 are laterally connected by a connecting member 80 that connects the inclined frames 78 to each other. The connecting member 80 is formed in a U shape whose front is open when viewed from above. The U-shaped arms are the mounting portions 80a extending rearward from the rear end of the inclined frame 78. Each belt 7 is placed on the mounting portion 80a.
A pulley 82 as a driving means for driving 0 is mounted. The connecting member 80 is fixed to the rear frame member 41 so as to connect the vertical members 41a and 41b of the rear frame member 41 of the frame 37.

Reference numeral 82 is a pulley, and each mounting portion 80a
The upper rotary shaft portion 74 is provided horizontally so that the axial direction thereof faces the front-rear direction. This pulley 82
Is the rear pulley referred to in the claims. Each pulley 82 is formed to have a diameter that is in close contact with the inner wall surface of the belt 70, and rotates in the direction of arrow C in FIG. 7 to transmit a driving force to the belt 70 to rotate the belt 70. A drive chain is hung on the rear side of the pulley 82, and a driving force from a driving device (not shown) is transmitted. Further, a holding pulley 84 is provided so as to be inscribed inside the lower end of the front rotation shaft portion 76. The holding pulley 84 is the front pulley in the claims, and is provided such that the axis thereof is oriented vertically so as to project downward of the front end of the inclined frame 78. The holding pulley 84 does not drive itself, but rotates freely as the belt 70 is driven by the pulley 82.

On the lower surface of the inclined frame 78, in order to hold not only the holding pulley 84 forming the front rotating shaft portion 76 as described above, but also the entire arc portion 85 on the lower side of the belt 70, A plurality of holding pulleys 86 are provided. The holding pulleys 86, 86 ... Also have a diameter such that they can be brought into close contact with the inner surface of the belt 70, and rotate freely in the direction of arrow C in FIG. 7 as the belt 70 is driven by the pulley 82. As described above, since the plurality of holding pulleys 84 are provided, the belt 70 can surely hold the spherical vegetables without being crushed when holding the spherical vegetables on the lower side. You can

The surface of each of the belts 70, 70 is provided with a plurality of concavo-convex portions 88 for surely holding the spherical vegetables. In this embodiment, the concave-convex portion 88 is formed by forming urethane or the like into a rectangular parallelepiped and sticking it on the surface of the belt 70. By providing the concavo-convex portion 88 in this manner, the spherical vegetables are surely held at the time of transportation and are not damaged.

The fixed shaft 72 and the cap 89 are shown in FIG. The upper side of the fixed shaft 72 is a screw rod 72a.
The screw rod 72a is provided with a cap 89 for holding the apex of the belt 70, that is, the intersection of the upper rotary shaft portion 74 and the front rotary shaft portion 76 on the fixed shaft 72. . The cap 89 is formed separately from the screw portion 89a in which a screw hole 90 into which the screw rod 72a can be screwed is formed, and the screw portion 89a, and is rotatable with respect to the screw rod 72a. It is composed of a bearing portion 89b having an insertion hole 91 formed at the center thereof. The apex of the belt 70 (the upper rotary shaft portion 74 and the front rotary shaft portion 76
(Intersection point with) is fixed to the upper end of the bearing portion 89b, and the belt rotates around the fixed shaft 72. Therefore, by providing a bearing 92 as a bearing on the inner wall side of the insertion hole 91 as shown in FIG. 9, the belt 70 can be rotated more smoothly.

Since the insertion hole 91 has a diameter that allows it to rotate freely with respect to the fixed shaft 72, the bearing portion 89b tends to descend along the axial direction of the fixed shaft 72 due to the weight of the belt 70 itself ( Arrow E in FIG. 9). on the other hand,
The inner wall surface of the arc-shaped lower end portion 85 of the belt 70 is in contact with the pulley 82. Therefore, even if the above-mentioned bearing portion 89b tries to descend, the pulley 82, which is aligned with the position of the inner wall surface of the lower end portion 85 of the belt 70, comes into contact with the inner wall surface of the belt 70, and the force that the bearing portion 89b tries to descend. I'm going to face you.

The belt 70 has a bearing portion 89b.
On the other hand, the belt 70 tends to sag at all times because it tries to descend due to its own weight, while the lower end is pressed by the pulley 82 so as not to descend. But,
Above the bearing portion 89b, the screw rod 72 of the fixed shaft 72 is provided.
Since the screw portion 89a that is screwed into a is provided, if the belt 70 is slack, it is possible to loosen the screw portion 89a and raise the bearing portion 89b by the elastic force of the belt 70 itself. If the belt 70 is stretched and can be further spaced from the pulley 82,
The belt 70 can be brought into close contact with the pulley 82 by tightening the screw portion 89a. Thus, by providing the cap 89 capable of adjusting the tension of the belt 70 at the position of the apex of the cone, even with a belt conveyor having pulleys that are not oriented in parallel to each other as in the present invention,
It is possible to prevent the slack of the belt or the tension of the belt excessively, and it is possible to favorably carry the carrying work.

As described above, the conveying device 36 is arranged along the circular arc located at the lower end portion 85 of the belt 70 formed in the shape of a quarter of a circle in a side view (direction of arrow D in FIG. 8).
The spherical vegetables are conveyed upward. Therefore, it is possible to raise the spherical vegetables harvested at a steeper angle than the conventional transport device. By elevating the spherical vegetables at a steep angle in this way, a longer distance is required to elevate the same height in the related art, whereas in the present embodiment, a shorter distance H is used. You can Therefore, the transport device can be downsized.

As described above, the belt holds the spherical vegetables in one place even when it is raised at a steep angle, and the belt does not hold different places in many places, so that the spherical vegetables should not be damaged as much as possible. can do. Also, because the transport path is short, for example, the position adjustment of the cutting blade is bad,
Even if the harvested spherical vegetables are scratched, if you stop the harvesting work when you notice that it is scratched, the transport distance will be shorter compared to the conventional equipment that has a long transport distance. The number of scratched vegetables in the transport device is small, and the vegetables can be prevented from being wasted.

Further, when the spherical vegetables are cut and conveyed to the conveying device, they first come into contact with the belts 70 provided on the left and right sides, but like the embodiment of the present invention, the holding pulley. If the front rotary shaft portion 76 by 84 is provided so as to extend in a substantially vertical direction, the belt hits the spherical vegetables perpendicularly, so the spherical vegetables are securely held, and the spherical vegetables are suddenly conveyed upward. Therefore, it is possible to prevent the spherical vegetables from entering between the belts smoothly as the traveling means advances. Further, in such a transport device, belts are provided on both the left and right sides of the transport path, and the lower surface is open so that the ground can be seen. Therefore, the vegetable waste adhering to the spherical vegetables after mowing is below the ground. Since it falls into the area, it is possible to prevent such waste such as vegetable waste from being transported.

Although the present invention has been variously described with reference to the preferred embodiments, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. Of course.
