[Figure 2] This is a perspective view of a carrot harvesting machine according to one embodiment of the present invention. [Figure 3] This is a plan view of a carrot harvesting machine according to a second embodiment of the present invention. [Figure 4] This is a perspective view of a carrot harvesting machine according to a second embodiment of the present invention. [Modes for carrying out the invention]

[0012] A carrot harvester, a type of root vegetable harvester shown as one embodiment of the present invention, will be described below. In the following, the forward direction of the machine will be referred to as front, back, left, and right.

[0013] <Overall Structure> The carrot harvesting machine consists of a driving section A that moves the machine, a control section B where the operator sits, a harvesting section C that pulls carrots out of the field on one side of the machine and transports them to the upper rear of the machine, a stem and leaf cutting section that takes over the carrots from the harvesting section C and transports them to the rear of the machine while cutting the stems and leaves, a residual leaf processing section that receives the carrots that fall from the stem and leaf cutting section and processes the remaining stems and leaves on the carrots in the residual leaf processing section, a sorting and transporting section D that takes over the carrots from the residual leaf processing section and transports the carrots from one side of the machine to the other side, and an auxiliary worker sorts the carrots while they are being transported, and a storage section E that holds the storage members for the carrots discharged from the sorting and transporting section D.

[0014] <Running section A> Below the machine frame 1, left and right drive sprockets 2,2 on the front side of the machine and left and right driven wheels 3,3 on the rear side of the machine are attached, and left and right belts 5,5 are wrapped around a plurality of idler wheels 4 mounted between the left and right drive sprockets 2,2 and the left and right driven wheels 3,3 to form the left and right crawlers 6L,6R. The left and right drive sprockets 2,2 of the left and right crawlers 6L,6R are attached to left and right drive shafts that extend from the transmission case, through which the engine's power is transmitted, and the left and right crawlers 6L,6R are attached to the machine frame 1 with a certain distance between them.

[0015] <Control Unit B> A control panel frame 7 is attached to the upper right side of the aircraft frame 1, and a cockpit seat 8 is attached to the control panel frame 7. A control panel 9 is also attached to the front of the aircraft. A gear shift lever 10 for switching between forward and reverse movement and travel speed is attached to the control panel 9, as well as a lifting lever 11 for controlling left and right turning of the aircraft and the working height of the harvesting unit C.

[0016] Further, a radiator cover 12 that protects a radiator (not shown) for cooling the engine and takes in cooling air is detachably attached to the other side (right side of the machine body) of the control unit frame 7 on the left and right sides of the machine body, thereby constituting the control unit B.

[0017] With the above configuration, by providing control members such as the shift operation lever 10 and the lift operation lever 11 that can perform a plurality of operations with one member, the operation of the machine body becomes easy, so the work of the operator can be reduced.

[0018] <Harvesting unit C> Left and right driven pulleys 14a, 14a are rotatably mounted on the front side of the machine body of the left and right extraction frames 13, 13, left and right drive pulleys 14b, 14b are mounted on the rear side of the machine body, and left and right clamping and conveying belts 15, 15 for pulling out carrots and conveying them to the rear part of the machine body are wound between the left and right driven pulleys 14a, 14a and the left and right drive pulleys 14b, 14b. At the same time, the left and right clamping and conveying belts 15, 15 are tensioned by a plurality of tension rollers 16, and the inner side surfaces of the left and right clamping and conveying belts 15, 15 are pressed against each other to form a carrot extraction and conveying path R. Then, a rotating frame that is rotatable in the vertical direction with a left and right horizontal axis as a rotation fulcrum is attached above the machine body frame 1, and a transmission case that transmits driving force to the left and right drive pulleys 14b, 14b is attached to the rear end portion of the rotating frame so as to be vertically rotatable around the rotation fulcrum. Further, the machine body frame 1 and the rotating frame are connected by a lifting cylinder, and the lifting cylinder is attached so as to be operable by the control unit B to constitute an extraction and conveying device 17.

[0019] In addition, a vertical lifting device 18 for lifting the foliage part of the carrot is provided in front of the extraction and conveying device 17, a horizontal lifting device 19 for scooping up the foliage part lifted by the vertical lifting device 18, a weeding rod 20 provided at the front part of the horizontal lifting device 19, a rotatable gauge wheel for preventing the carrot from slipping down after passing through the extraction and conveying device 17, and a left and right vibrating soiler that reciprocally vibrates with the driving force of the engine to loosen the soil on the left and right sides of the carrot in the soil are provided.

[0020] Then, a tail-cutting device for cutting the root hairs of carrots being transported by the carrot-pulling device 17 is attached below the aforementioned pulling and transporting path R, which serves as the pulling and transporting passage, thereby forming the harvesting section C.

[0021] With the above configuration, by providing a horizontal lifting device 19 equipped with a weed-dividing rod 20 on the front of the machine body and a vertical lifting device 18, harvesting can be performed while lifting the stems and leaves of carrots that have fallen over in the field. This improves the visibility of the carrots to be harvested, making it easier to align the pulling position, and reduces the amount of crop left behind, thus improving work efficiency.

[0022] Furthermore, it prevents the carrots from being damaged by contact with the left-right vibrating soiler, thus improving the market value of the carrots.

[0023] Furthermore, by connecting the machine frame 1 and a rotating frame that can rotate vertically with the left and right lateral axes as pivot points using a lifting cylinder, and by extending and retracting the lifting cylinder by operating the lifting operation lever 11 on the control unit B, the vertical height of the entire harvesting unit C can be adjusted by operating the lifting operation lever 11. This allows for vertical adjustment of the starting position of the pulling and conveying end of the harvesting unit C, and also allows for adjustment of the starting position of the pulling and conveying end to match the appropriate pulling height of the carrots planted in the field, thereby preventing carrots from being left behind and improving work efficiency.

[0024] Furthermore, raising the harvesting unit C during turning makes it less likely for the lower end of the harvesting unit C to come into contact with the field, resulting in smoother turning and improved work efficiency.

[0025] <Sorting and Conveying Section D> The sorting and conveying device 21 for sorting operations in the sorting and conveying section D is positioned in the left-right direction of the machine, from the rear and below the pull-out conveying device 17 of the harvesting section C toward the storage section E, which contains the flexible container bags 22 that hold the harvested crops. It consists of a chain conveyor with slats at regular intervals that rotates using the driving force from the engine. When carrots are transported with their stems and leaves held by the pull-out conveying device 17, the lower end of the stems and leaves (slightly above the top of the carrot) is cut off at the stem and leaf cutting section, causing the carrot to fall downwards. The falling carrot is then received by the remaining leaf processing section, where the remaining stems and leaves are processed and transported to the sorting and conveying section D. The sorting and conveying device 21 in the sorting and conveying section D then transports the carrot from its left end to its right (to the storage section E).

[0026] Furthermore, an auxiliary work seat 23 is provided on the rear side of the sorting and conveying device 21. An operator seated in the auxiliary work seat 23 removes unsuitable carrots (small or irregularly shaped carrots) from the carrots being transported by the sorting and conveying device 21, and sends only carrots with appropriate commercial value to the storage section E.

[0027] <Storage Area E> The storage section E is located to the right of the sorting and conveying device 21 and consists of a suspension hanger 24 provided at the right end of the sorting and conveying device 21, a mounting platform 25 on which the flexible container bags 22 suspended from the suspension hanger 24 are placed, and a crane 26 for lifting the flexible container bags 22 placed on the mounting platform 25 and lowering them into the field.

[0028] The sorting and conveying device 21 is positioned diagonally upward from its left base to its upper right end. That is, it rotates using the power from the engine to convey the carrots diagonally upward and releases them downward from the upper end. The base of the sorting and conveying device 21 is rotatable on a pivot shaft, and the piston tip of an up-and-down hydraulic cylinder, whose base is pivotally supported on the machine frame 1, is connected to the middle section. That is, when an operator seated in the auxiliary work seat 23 steps down on the up switch, the up-and-down hydraulic cylinder extends and rotates around the pivot shaft to raise the sorting and conveying device 21, and when the operator steps down on the down switch, the up-and-down hydraulic cylinder retracts and rotates around the pivot shaft to lower the device.

[0029] The suspension hanger 24 is located at the right end of the sorting and conveying device 21. Above the mounting table 25, the four hooks 24a of the suspension hanger 24 are hooked onto the locking holes on the upper edge of the flexible container bag 22 to suspend and support the flexible container bag 22. At this time, the sorting and conveying device 21 is raised to a position where the bottom of the suspended flexible container bag 22 is supported by the mounting table 25.

[0030] The mounting platform 25 is provided with a pivot shaft at the right end of the aircraft frame 1, allowing it to be freely switched between a state of use where it extends horizontally to the right and a state of storage where it is folded inside the aircraft.

[0031] The crane 26 consists of a crane support frame 27 fixed to the rear end of the machine frame 1 and positioned facing rearward, a vertical frame 28 made of cylindrical pipe material fixed to the upper surface of the crane support frame 27 and positioned upward, a rotating support column 29 inserted into the vertical frame 28 and rotatable, a horizontal frame 30 fixed to the upper end of the rotating support column 29 and extending laterally, an electric motor 31 that rotates the rotating support column 29, a winch 32 provided near the base of the horizontal frame 30, a guard body 33 fitted around the outer circumference of the vertical frame 28 and rotating around the vertical frame 28, and an operation panel 34 provided near the base of the guard body 33.

[0032] The winch 32 is a typical winch that uses a built-in electric motor to wind in and unwind the wire 35, and a hook 36 is provided at the end of the wire 35. The built-in electric motor is activated by an up / down switch 37 on the control panel 34 to wind in or unwind the wire 35, thereby raising or lowering the hook 36. In other words, by hooking the suspension string 22a of the flexible container bag 22 onto the hook 36, the flexible container bag 22 can be raised or lowered.

[0033] The electric motor 31 is operated by a swivel switch 38 located on the control panel 34, which rotates the rotating support column 29, causing the horizontal frame 30 to swivel and allowing the flexible container bag 22 suspended by the hook 36 of the winch 32 to be swung to any desired position.

[0034] The guard body 33 consists of a rotating cylinder 33a made of cylindrical pipe material fitted onto the outer circumference of the vertical frame 28, upper and lower horizontal guard members 33b made of cylindrical pipe material with their bases fixed to the rotating cylinder 33a and extending laterally, and a U-shaped guard member 33c inserted from the tip of the upper and lower horizontal guard member 33b and fixed so as to be able to move back and forth in the direction of arrows A to B.

[0035] Furthermore, a fixing pin 33d is provided on the rotating cylinder 33a fitted around the outer circumference of the vertical frame 28, fixing the rotational position of the rotating cylinder 33a around the vertical frame 28. In other words, as shown in Figure 1, when a worker detaches the flexible container bag 22 from the hook 36 and lowers it into the field, the guard body 33 is fixed in a position to protect the worker from being hit even if the flexible container bag 22 falls towards them.

[0036] Furthermore, it is safer to provide a position detection potentiometer on the rotating cylinder 33a of the guard body 33 so that the winch 32 does not operate even if the up / down switch 37 on the control panel 34 is operated, unless the guard body 33 is positioned to protect the worker from being hit even if the flexible container bag 22 falls towards the worker (position in Figure 1).

[0037] Furthermore, by retracting the U-shaped guard material 33c in the direction of the arrow L relative to the upper and lower lateral guard materials 33b, and rotating the guard body 33 to the left and right so that it is parallel to the rear end of the machine, and fixing it with the fixing pin 33d, and by rotating the lateral frame 30 of the crane 26 to the rear position of the machine, the width of the machine is narrowed, making it safer and easier to operate when driving on roads or loading and unloading the machine onto trucks, and allowing the machine to be stored in a narrow space when storing it in a barn or the like.

[0038] Furthermore, since the vertical frame 28 (center of rotation) of the crane 26 is positioned at the rear of the right end of the machine frame 1, near the rear of the auxiliary work seat 23, the crane 26 does not interfere with the sorting work of the worker seated in the auxiliary work seat 23, resulting in good work efficiency.

[0039] Furthermore, when the crane 26 is not in use during harvesting, the lateral frame 30 can be positioned towards the rear of the machine so as not to interfere with the sorting work of the worker seated in the auxiliary work seat 23, and also not get in the way when the worker sits in or leaves the auxiliary work seat 23. Moreover, when the crane 26 is in use, it can be quickly rotated to a position above the flexible container bags 22, resulting in improved work efficiency.

[0040] <Carrot harvesting work> The mounting platform 25 is moved from its stored state, folded inward within the aircraft, to a usable state, extending horizontally to the right (as shown in Figure 1).

[0041] Then, the locking holes on the upper edge of the flexible container bag 22 are hooked onto each hook 24a of the suspension hanger 24 at the right end of the sorting and conveying device 21, and the flexible container bag 22 is suspended, and the sorting and conveying device 21 is raised to a position where the bottom of the suspended flexible container bag 22 is supported by the mounting table 25.

[0042] Then, position the guard body 33 to protect the worker from being hit even if the flexible container bag 22 falls towards the worker (position shown in Figure 1), and secure it with the fixing pin 33d. The lateral frame 30 of the crane 26 should be positioned facing the rear of the machine.

[0043] Then, the carrot harvester is advanced, and after aligning the front end of the extraction and conveying path R of the extraction and conveying device 17 of the harvesting section C with the carrot rows in the field, the lifting and lowering operation lever 11 is operated to lower the harvesting section C, the digging clutch is turned "on", and each part is driven to move forward. As a result, the weed divider 20, the vertical lifting device 18, and the horizontal lifting device 19 rake up the stems and leaves of the carrots, and the stems and leaves of the carrots are gripped in the extraction and conveying path R of the extraction and conveying device 17. The left and right vibrating soil loosens the soil on the sides and below the carrots, and the carrots are gripped and pulled out by the extraction and conveying device 17 and conveyed upward and to the rear.

[0044] Then, the carrots, which have been transported with their stems and leaves held by the extraction and transport device 17, are cut at the lower end of their stems and leaves (slightly above the top of the carrot) by the stem and leaf cutting section, and the carrots fall downwards. The falling carrots are then received by the remaining leaf processing section, where the remaining stems and leaves are processed and the carrots are transported to the sorting and transport section D. The carrots are then transported from their left end to their right (to the storage section E) by the sorting and transport device 21 in the sorting and transport section D.

[0045] Then, an operator seated in the auxiliary work seat 23 at the rear of the sorting and conveying device 21 removes carrots that are not suitable for sale (small carrots or oddly shaped carrots) from among the carrots being sent by the sorting and conveying device 21, and only carrots with commercial value are sent to the storage section E.

[0046] The carrots that have been sent to the right end by the sorting and conveying device 21 fall into the flexible container bags 22 suspended from each hook 24a of the hanging hanger 24 at the right end of the sorting and conveying device 21 and are stored there.

[0047] Then, when the flexible container bag 22 is full of carrots, the machine stops moving and the drive of its various parts stops, the worker seated in the auxiliary work seat 23 leaves and stands behind the guard body 33, and operates the swivel switch 38 on the control panel 34 to swivel the lateral frame 30 from the position facing the rear of the machine so that the hook 36 of the winch 32 is positioned above the center of the flexible container bag 22.

[0048] Then, the up / down switch 37 on the control panel 34 is operated to the down position to lower the hook 36 to the central upper position of the flexible container bag 22.

[0049] Then, the guard body 33 is moved from the rear to the mounting platform 25, and the user is placed on the mounting platform 25, and the hook 36 is attached to the hanging string 22a of the flexible container bag 22.

[0050] Then, the guard body 33 is returned to the rear, the up / down switch 37 on the control panel 34 is operated to the up position to lift the flexible container bag 22 from the mounting platform 25, the swivel switch 38 on the control panel 34 is operated to swivel the flexible container bag 22 to the rear position (the position of the dashed line in Figure 1) to the right outer side of the mounting platform 25, and the up / down switch 37 is operated to the down position to lower the flexible container bag 22 into the field. Then, the hook 36 is detached from the suspension string 22a of the flexible container bag 22, the up / down switch 37 is operated to the up position to raise the hook 36, and the swivel switch 38 is operated to return the lateral frame 30 to the position facing the rear of the machine.

[0051] Then, the worker hooks the locking holes on the upper edge of the empty flexible container bag 22 onto each hook 24a of the suspension hanger 24 at the right end of the sorting and conveying device 21, suspending the flexible container bag 22 so that the bottom of the flexible container bag 22 is supported on the mounting platform 25, and then sits down on the auxiliary work seat 23. Then, the worker drives the various parts to move the machine forward and resumes the harvesting work.

[0052] In short, the flexible container bags 22 placed on the mounting platform 25 are lifted by the crane 26 and lowered into the field at a position to the right rear of the mounting platform 25. Therefore, even if the flexible container bags 22 tilt or the machine moves slightly, contact with the machine can be avoided, allowing for good and appropriate harvesting.

[0053] <Other Embodiments> Figures 3 and 4 show a second embodiment, in which the configuration of the sorting and conveying section D and the storage section E differs from that of the first embodiment.

[0054] Specifically, the sorting and conveying device 21 of the sorting and conveying section D is configured to be movable in the left-right direction of the machine by a sliding electric cylinder 39 operated by a slide switch located near the auxiliary work seat 23, and the position of the sorting and conveying device 21 is detected by a position detection sensor 40, and it stops at the left end and right end positions of the machine.

[0055] When the sorting and conveying device 21 is at the left end of the machine, the carrots harvested in the harvesting section C are transported by the sorting and conveying section D to the storage section E and stored in the flexible container bags 22. When the sorting and conveying device 21 is at the right end of the machine, the flexible container bags 22 are lowered into the field as described later.

[0056] The storage section E is located behind the right end of the sorting and conveying device 21 and consists of a rotating base that rotates around a vertical rotation axis provided at the right end of the sorting and conveying device 21, a movable conveyor 41 whose base is pivotally supported on the rotating base and whose upper end moves up and down by an electric cylinder, and which is driven by an engine to move around and transport carrots guided and conveyed from the right end of the sorting and conveying device 21 diagonally upward, a suspension hanger 24 provided at the upper end of the movable conveyor 41, and a mounting platform 25 located at the lower rear of the right end of the sorting and conveying device 21 on which flexible container bags 22 can be placed.

[0057] The rotation axis of the rotating base is located at the right end of the sorting and conveying device 21, so it moves left and right in conjunction with the left and right movement of the sorting and conveying device 21. When the sorting and conveying device 21 is at the right end, the rotation axis of the rotating base is located off-center to the right of the machine body relative to the left and right center line of the running section A. Therefore, when the rotating base is rotated to tilt the movable conveyor 41 45 degrees to the right rear, the position where the flexible container bag 22, which is full of carrots, is removed from the hanging hanger 24 and lowered into the field is further away from the machine body to the right outer side, so the lowered flexible container bag 22 does not interfere with the harvesting work, resulting in improved work efficiency.

[0058] Furthermore, the base of the support frame 42, which supports the auxiliary work seat 23 on which the auxiliary worker sits, is fixed to the rotating base, and the auxiliary work seat 23 and the movable conveyor 41 rotate together in the same direction. Therefore, the auxiliary worker sitting in the auxiliary work seat 23 can perform both the task of hanging the flexible container bags 22 on the hanging hanger 24 with the movable conveyor 41 facing straight back, and the task of removing the flexible container bags 22 from the hanging hanger 24 with the movable conveyor 41 tilted 45 degrees to the right rear, all while remaining in the auxiliary work seat 23, resulting in good work efficiency. The auxiliary worker sitting in the auxiliary work seat 23 performs the sorting task of removing substandard carrots from the carrots that have been transported to the right end of the sorting and conveying device 21. The worker stands in the field, holds the auxiliary work seat 23, and rotates the rotating base via the support frame 42.

[0059] The movable conveyor 41 is positioned below the right end of the sorting and conveying device 21 at its lower end and is angled upward. Specifically, the movable conveyor 41 rotates using power from the engine, and at the right end of the sorting and conveying device 21, the carrots being conveyed to the right are guided by a guide plate that is inclined at 45 degrees relative to the conveying direction, and the carrots are sent with their conveying direction changed to the rear. The movable conveyor 41 then conveys them angled upward and discharges them downward from its upper end.

[0060] Furthermore, the base of the movable conveyor 41 is pivotally supported on a rotating base, and the piston tip of an electric cylinder, whose base is pivotally supported on the rotating base, is connected to the middle section. That is, the upper end of the movable conveyor 41 moves up and down by operating a lifting lever 43 provided on the side of the auxiliary work seat 23 to extend and retract the electric cylinder. The support frame 42 that supports the auxiliary work seat 23 is provided with outriggers 44, and when the lifting lever 43 is operated, the outriggers 44 move downward to support the support frame 42, i.e., the sorting and conveying device 21.

[0061] Furthermore, if the sliding electric cylinder 39 can be activated by operating a slide switch located near the auxiliary work seat 23 only when the parking brake is activated by the parking lever 45 of the control unit B, the sorting and conveying device 21 of the sorting and conveying unit D can be moved to the right of the machine, the rotating base can be rotated to the right outward, and the flexible container bags 22 can be lowered into the field using the lifting lever 43, then the operation of lowering the flexible container bags 22 into the field can be performed only when the machine is stopped, thus ensuring safety.

[0062] Furthermore, when the sliding electric cylinder 39 is operated by operating a slide switch located near the auxiliary work seat 23 to move the sorting and conveying device 21 of the sorting and conveying unit D to the right of the machine, when the rotating base is rotated outwards to the right, and when the flexible container bags 22 are lowered into the field using the lifting lever 43, the work status is displayed on the monitor of the control panel 9 of the control unit B. If an alarm sound or an alarm voice (in various languages) indicating the work status is emitted, the operator seated in the cockpit 8 of the control unit B can recognize that the auxiliary worker is lowering the flexible container bags 22 into the field, thus avoiding unforeseen situations such as inadvertently moving the machine forward, ensuring safety.

[0063] Furthermore, when the sorting and conveying device 21 is not located at the left end of the aircraft, it is safe to prevent the aircraft from taking off even if the pilot seated in the cockpit seat 8 of the control unit B attempts to move the aircraft forward, and to issue a warning.

[0064] With the movable conveyor 41 facing straight backward, the suspension hanger 24 hooks 29a of the suspension hanger 24 onto the locking hole on the upper edge of the flexible container bag 22 to suspend and support the flexible container bag 22. At this time, the bottom of the flexible container bag 22 is supported by the mounting base 25. [Explanation of Symbols]
