[Figure 4] FIG. 11 is a perspective view of a carrot harvester according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] A carrot harvester, which is a type of root vegetable harvester, will be described as an embodiment of the present invention. In the following, the forward direction of the machine body will be used as a reference to refer to front, rear, left and right.

[0013] <Overall composition> The carrot harvester is composed of a traveling section A that drives the machine, a control section B on which the operator sits, a harvesting section C that pulls out carrots from the field on one side of the machine body and transports them to the upper rear of the machine body, a sorting and transporting section D that takes over carrots from the harvesting section C and transports them to the rear of the machine body in a stem and leaf cutting section where the stems and leaves are cut, a remaining leaf processing section D that receives carrots that fall from the stem and leaf cutting section and processes the stems and leaves remaining on the carrots, a sorting and transporting section D that takes over carrots from the remaining leaf processing section and transports them from one side of the machine body to the other side of the machine body where an assistant operator sorts the carrots during transport, and a storage section E that holds storage materials for the carrots discharged from the sorting and transporting section D.

[0014] <Running section A> Left and right crawlers 6L, 6R are formed by winding left and right belts 5, 5 around left and right driving sprockets 2, 2 on the front side of the machine body and left and right driven wheels 3, 3 on the rear side of the machine body below the machine body frame 1, and multiple wheels 4 attached between the left and right driving sprockets 2, 2 and the left and right driven wheels 3, 3. The left and right driving sprockets 2, 2 of the left and right crawlers 6L, 6R are attached to left and right drive shafts extending to both the left and right sides from a transmission case to which the engine power is transmitted, and the left and right crawlers 6L, 6R are attached to the machine body frame 1 with a certain left-right interval between them.

[0015] <Control Unit B> A control frame 7 is attached to the upper right side of the machine frame 1, and a control seat 8 is attached to the control frame 7, and a control panel 9 is attached to the front of the machine. A speed change lever 10 for switching between forward and reverse movement and the traveling speed of the machine is attached to the control panel 9, and a lift control lever 11 for turning the machine left and right and for controlling the working height of the harvesting section C is also attached.

[0016] A radiator cover 12 that protects a radiator (not shown) that cools the engine and takes in cooling air is detachably attached to the other side (right side) of the control unit frame 7, thereby forming a control unit B.

[0017] With the above configuration, by providing a control member such as the gear shift control lever 10 and the lift control lever 11 that can perform multiple operations with one lever, control of the aircraft becomes easier, thereby reducing the workload of the pilot.

[0018] <Harvesting Section C> Left and right driven pulleys 14a, 14a are rotatably attached to the front sides of the left and right pulling-out frames 13, 13, and left and right driving pulleys 14b, 14b are attached to the rear sides of the machine, and left and right clamping conveyor belts 15, 15 for pulling out carrots and transporting them to the rear of the machine are wound around the left and right driven pulleys 14a, 14a and the left and right driving pulleys 14b, 14b. The left and right clamping conveyor belts 15, 15 are tensioned by a plurality of tension rollers 16, and the inside surfaces of the left and right clamping conveyor belts 15, 15 are pressed against each other to form a carrot pulling and transport path R. A rotating frame is attached above the machine frame 1 so as to be vertically rotatable about left and right horizontal axes as rotation fulcrums, and a transmission case for transmitting driving force to the left and right driving pulleys 14b, 14b is attached to the rear end of the rotating frame so as to be vertically rotatable about the rotation fulcrum. The machine 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 a drawing and conveying device 17.

[0019] Also provided in front of the pulling-out and conveying device 17 are a vertical raising device 18 for raising the stems and leaves of carrots, a horizontal raising device 19 for scooping up the stems and leaves raised by the vertical raising device 18, a grass separating rod 20 provided in front of the horizontal raising device 19, a rotatable gauge wheel for preventing the pulling-out and conveying device 17 from descending too far, and a left-right vibrating soiler that vibrates back and forth with the driving force of the engine to loosen the soil on the left and right of the carrots buried in the soil.

[0020] A tail cutting device for cutting the roots of carrots being transported by the pulling and conveying device 17 is attached below the pulling and conveying path R as a pulling and conveying passage, thereby forming a harvesting section C.

[0021] With the above-mentioned configuration, by providing the horizontal pulling-up device 19 equipped with the grass-dividing rod 20 on the front side of the machine body and the vertical pulling-up device 18, harvesting work can be performed while raking up the stems and leaves of carrots that have fallen in the field, and since visibility of the carrots to be harvested is improved, it is easier to adjust the pulling position and the amount of crop left behind is reduced, improving work efficiency.

[0022] In addition, since the carrots can be prevented from being damaged by contact with the left-right vibrating soy grinder or the like, the commercial value of the carrots is improved.

[0023] The body frame 1 and a rotating frame that can rotate freely up and down around the left and right horizontal axes are connected by a lifting cylinder, and the lifting cylinder is extended and retracted by operating the lifting operation lever 11 of the control unit B. This makes it possible to adjust the vertical height of the entire harvesting unit C by operating the lifting operation lever 11, so that the position of the pulling-out transport starting end of the harvesting unit C can be adjusted up and down and the position of the pulling-out transport starting end can be adjusted to match the appropriate pulling-out height of the carrots growing in the field, preventing any carrots from being left behind and improving work efficiency.

[0024] Furthermore, if the harvesting section C is raised during turning, the lower end of the harvesting section C is less likely to come into contact with the field, so that the turning operation can be performed smoothly and work efficiency is improved.

[0025] <Sorting and conveying section D> The sorting and conveying device 21 for sorting work in the sorting and conveying section D is arranged in the left-right direction of the machine body from the rear lower part of the pulling and conveying device 17 in the harvesting section C toward the storage section E where the flexi-con bags 22, which are storage members for storing harvested crops, are located, and is composed of a chain conveyor with bars at regular intervals that rotates by the driving force from the engine. The carrots conveyed by the pulling and conveying device 17 with their stems and leaves clamped are cut at the stem and leaf cutting section at their lower ends (slightly above the heads of the carrots) and the carrots fall downward, but the remaining leaf processing section receives the fallen carrots and processes the stems and leaves remaining on the carrots before conveying them to the sorting and conveying section D. The sorting and conveying device 21 in the sorting and conveying section D conveys the carrots from their left ends to the right (storage section E).

[0026] In addition, an auxiliary work seat 23 is provided on the rear side of the body of the sorting and conveying device 21, and a worker seated on the auxiliary work seat 23 removes non-marketable carrots (small carrots or carrots with irregular shapes) from the carrots sent by the sorting and conveying device 21, and sends only carrots with proper market value to the storage section E.

[0027] <Containment Section E> The storage section E is located to the right of the sorting and conveying device 21, and is composed of a hanging hanger 24 provided at the right end of the sorting and conveying device 21, a loading platform 25 on which the flexi-con bag 22 hung from the hanging hanger 24 is placed, and a crane 26 that hoists the flexi-con bag 22 placed on the loading platform 25 and lowers it into the field.

[0028] The sorting and conveying device 21 is provided from the base at the left end toward the upper right end, extending obliquely upward. That is, it rotates by the driving force from the engine to convey the carrots obliquely upward and release them downward from the upper end. The base of the sorting and conveying device 21 is provided so as to be rotatable about a rotating shaft, and the piston tip of a vertically operating hydraulic cylinder whose base is pivotally supported on the machine frame 1 is connected to its middle part. That is, while the operator seated on the auxiliary work seat 23 depresses an up switch operated by the operator, the vertically operating hydraulic cylinder extends and rotates about the rotating shaft to rise, and while the operator depresses a down switch, the vertically operating hydraulic cylinder contracts and rotates about the rotating shaft to lower.

[0029] The hanging hanger 24 is provided at the right end of the sorting and conveying device 21. The four hooks 24a of the hanging hanger 24 are hooked onto locking holes in the upper edge of the flexi-con bag 22 above the mounting table 25 to support the flexi-con bag 22 in a suspended state. At this time, the sorting and conveying device 21 is in an elevated position such that the bottom of the suspended flexi-con bag 22 is supported by the mounting table 25.

[0030] The mounting table 25 is provided so as to be freely switched between a usage state in which it extends horizontally to the right side by a pivot shaft provided at the right end of the body frame 1 and a storage state in which it is folded inside the body of the machine.

[0031] The crane 26 is composed of a crane support frame 27 whose base is fixed to the rear end of the body frame 1 and facing rearward, a vertical frame 28 made of cylindrical pipe material whose base is fixed to the upper surface of the crane support frame 27 and facing upward, a rotating pillar 29 inserted into the vertical frame 28 and rotatable, a horizontal frame 30 whose base is fixed to the upper end of the rotating pillar 29 and extends horizontally, an electric motor 31 that rotates and drives the rotating pillar 29, a winch 32 provided near the base of the horizontal frame 30, a guard body 33 fitted around the outer periphery of the vertical frame 28 and rotates 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 type that uses a built-in electric motor to wind in and pay out a wire 35, and a hook 36 is provided at the end of the wire 35. The built-in electric motor is operated by a lift / lower switch 37 provided on an operation panel 34 to wind in and pay out the wire 35, thereby raising and lowering the hook 36. In other words, by hooking the hanging string 22a of the flexi-con bag 22 onto the hook 36, the flexi-con bag 22 can be raised and lowered.

[0033] The electric motor 31 is operated by a rotation switch 38 provided on the operation panel 34, which rotates the rotating support 29 to rotate the horizontal frame 30, thereby rotating the FIBC bag 22 suspended by the hook 36 of the winch 32 to any desired position.

[0034] The guard body 33 is composed of a rotating cylinder 33a made of cylindrical pipe material fitted onto the outer periphery of the vertical frame 28, upper and lower horizontal guard members 33b made of cylindrical pipe material extending horizontally and whose bases are fixed to the rotating cylinder 33a, and a U-shaped guard member 33c inserted from the tips of the upper and lower horizontal guard members 33b and fixed so as to be able to move freely back and forth in the directions of the arrows A and B.

[0035] A fixing pin 33d is provided on the rotating cylinder 33a fitted onto the outer periphery of the vertical frame 28, and fixes the rotational position of the rotating cylinder 33a around the vertical frame 28. That is, as shown in Fig. 1, when an operator removes the FIBC bag 22 from the hook 36 and lowers it into the field, the guard body 33 is fixed in a position that protects the operator from being hit by the FIBC bag 22 even if the FIBC bag 22 falls toward the operator.

[0036] Furthermore, if a position detection potentiometer is provided on the rotating cylinder 33a of the guard body 33 and the guard body 33 is not placed in a position (position in FIG. 1) that protects the worker from being hit by the flexi-con bag 22 even if the flexi-con bag 22 falls toward him, the winch 32 will not operate even if the lift / lower switch 37 on the operation panel 34 is operated, thereby ensuring safety.

[0037] In addition, if the U-shaped guard material 33c is retracted in the direction of arrow R relative to the upper and lower horizontal guard materials 33b, the guard body 33 is rotated left and right until it is parallel to the rear end of the machine and fixed with fixing pin 33d, and the horizontal frame 30 of the crane 26 is rotated to a position at the rear of the machine, the left and right width of the machine will be narrowed, which will provide safety and ease of operation when traveling on the road or loading and unloading the machine onto a truck, and will allow the machine to be stored in a narrow space when stored in a barn, etc.

[0038] In addition, since the vertical frame 28 (center of rotation) of the crane 26 is positioned behind the right end of the body frame 1 and 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, improving workability.

[0039] In addition, when the crane 26 is not being used during harvesting work, if the horizontal frame 30 is directed toward the rear of the machine body, it will not get in the way of the sorting work of the worker seated in the auxiliary work seat 23, and it will not get in the way when the worker sits on or leaves the auxiliary work seat 23. Moreover, when the crane 26 is used, it can be quickly rotated to a position above the flexible container bag 22, improving workability.

[0040] <Carrot harvesting work> The mounting table 25 is folded inside the machine body to a stored state, and then moved to a usage state in which it extends horizontally to the right side (the state shown in FIG. 1).

[0041] Then, the flexi-con bag 22 is hung by hooking the locking holes at the upper edge of the flexi-con bag 22 onto each of the hooks 24a of the hanging hanger 24 at the right end of the sorting and conveying device 21, and the sorting and conveying device 21 is raised to a position where the bottom of the hanging flexi-con bag 22 is supported on the loading platform 25.

[0042] Then, the guard body 33 is placed in a position (the position shown in FIG. 1) that protects the worker from being hit by the flexible container bag 22 even if the flexible container bag 22 falls toward the worker, and is fixed with the fixing pin 33d. The horizontal frame 30 of the crane 26 is placed in a position facing the rear of the machine body.

[0043] The carrot harvester is then advanced until the front end of the pulling-out conveying path R of the pulling-out conveying device 17 of the harvesting section C is aligned with the carrot rows in the field, after which the lifting operation lever 11 is operated to lower the harvesting section C, and the digging clutch is turned "on" to drive each section and move forward. Then, the carrot stems and leaves are raked up by the weeding rod 20, vertical lifting device 18 and horizontal lifting device 19 and clamped on the pulling-out conveying path R of the pulling-out conveying device 17, the soil to the sides and below the carrots is loosened by the left and right vibrating soiler, and the carrots are clamped and pulled out by the pulling-out conveying device 17 and conveyed upward and rearward.

[0044] Then, carrots that have been transported with their stems and leaves clamped by pulling and conveying device 17 have their lower ends (slightly above the top of the carrot) cut off in the stem and leaf cutting section and the carrots fall downward, but the falling carrots are received by the remaining leaf processing section, which processes the stems and leaves remaining on the carrots and then transports them to the sorting and conveying section D. The carrots are then transported from their left end to the right (storage section E) by sorting and conveying device 21 in sorting and conveying section D.

[0045] Then, a worker seated on an auxiliary work seat 23 at the rear side of the body of the sorting and conveying device 21 picks out non-marketable carrots (small carrots or carrots with odd shapes) from the carrots sent by the sorting and conveying device 21, and only the carrots with market value are sent to the storage section E.

[0046] The carrots sent to the right end by the sorting and conveying device 21 drop into and are stored in the flexible container bags 22 hung from the hooks 24a of the hanging hangers 24 at the right end of the sorting and conveying device 21.

[0047] Then, when the flexi-con bag 22 is full of carrots, the movement of the machine and the operation of each part are stopped, and the worker seated in the auxiliary work seat 23 leaves his seat and stands behind the guard body 33, and operates the rotation switch 38 on the operation panel 34 to rotate the horizontal frame 30 from a position facing the rear of the machine so that the hook 36 of the winch 32 is positioned above the center of the flexi-con bag 22.

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

[0049] Then, the operator moves from the rear of the guard body 33 to the platform 25, stands on the platform 25, and hooks the hook 36 onto the hanging string 22a of the flexible container bag 22.

[0050] Then, the operator returns to the rear of the guard body 33, operates the lift / lower switch 37 on the operation panel 34 to UP to hoist the FIBC bag 22 from the platform 25, operates the swivel switch 38 on the operation panel 34 to swivel the FIBC bag 22 to a rear position (the position of the imaginary line in FIG. 1) on the right outer side of the platform 25, and operates the lift / lower switch 37 to DOWN to lower the FIBC bag 22 into the field. Then, the operator releases the hook 36 from the hanging string 22a of the FIBC bag 22, operates the lift / lower switch 37 to UP to raise the hook 36, and operates the swivel switch 38 to return the horizontal frame 30 to a position facing the rear of the machine body.

[0051] Then, the worker hangs the empty FIBC bag 22 by hooking the locking holes at the upper edge of the FIBC bag 22 onto the hooks 24a of the hanging hanger 24 at the right end of the sorting and conveying device 21, so that the bottom of the FIBC bag 22 is supported on the mounting table 25, and then sits down on the auxiliary work seat 23. Then, the worker drives each section to move the machine forward and resumes the harvesting work.

[0052] In summary, the flexi-con bag 22 placed on the platform 25 is lifted by the crane 26 and lowered into the field at a position on the outer right rear of the platform 25. Therefore, even if the flexi-con bag 22 lowered into the field tilts or the machine body meanders slightly, the flexi-con bag 22 can be prevented from coming into contact with the machine body, and good and appropriate harvesting work can be performed.

[0053] <Other embodiments> 3 and 4 show a second embodiment, which is different from the first embodiment in the configurations of a sorting and conveying section D and a storage section E.

[0054] That is, the sorting and conveying device 21 of the sorting and conveying section D is configured to be freely moved in the left and right directions of the body by operating a slide switch provided near the auxiliary work seat 23 using a slide electric cylinder 39, and the position of the sorting and conveying device 21 is detected by a position detection sensor 40 and stopped at the left end position and the right end position of the body.

[0055] When the sorting and conveying device 21 is located at the left end of the body, carrots harvested in harvesting section C are transported by sorting and conveying section D to storage section E and stored in flexi-con bags 22. When the sorting and conveying device 21 is located at the right end of the body, the flexi-con bags 22 are unloaded into the field, as described below.

[0056] Storage section E is located behind the right end of the sorting and conveying device 21 and is composed of a rotating base that rotates around a vertical axis of rotation provided at the right end of the sorting and conveying device 21, a movable conveyor 41 whose base is pivoted to the rotating base and whose upper end side moves up and down by an electric cylinder and has bars spaced at regular intervals that revolve by driving force from an engine to transport carrots guided and conveyed from the right end of the sorting and conveying device 21 diagonally upwards, a hanging hanger 24 provided at the upper end of the movable conveyor 41, and a loading platform 25 that is located at the lower rear of the right end of the sorting and conveying device 21 and on which flexi-con bags 22 can be placed.

[0057] The rotation shaft of the rotating base is provided at the right end of the sorting and conveying device 21, and therefore moves left and right together with the left and right movement of the sorting and conveying device 21. When the sorting and conveying device 21 is at its rightmost position, the rotation shaft of the rotating base is provided at a position offset to the right of the machine body from 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 rearward and to the right, the position at which the flexi-con bags 22 filled with carrots are removed from the hanging hangers 24 and lowered into the field is at a position on the outer right side of the machine body, farther away from the machine body, and the lowered flexi-con bags 22 do not interfere with the harvesting work, improving workability.

[0058] In addition, the base of the support frame 42 that 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 integrally in the same direction. Therefore, the auxiliary worker on the auxiliary work seat 23 can perform the work of hanging the FIBC bag 22 on the hanging hanger 24 with the movable conveyor 41 facing straight backward, and the work of removing the FIBC bag 22 from the hanging hanger 24 with the movable conveyor 41 tilted 45 degrees backward to the right side, while remaining on the auxiliary work seat 23, which improves workability. The auxiliary worker seated on the auxiliary work seat 23 performs a sorting work of removing non-standard carrots from the carrots transported to the right end of the sorting and transporting 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 provided facing diagonally upward with its lower portion located below the right end of the sorting and conveying device 21. That is, the movable conveyor 41 rotates by driving force from the engine, and when carrots are being conveyed rightward at the right end of the sorting and conveying device 21, they are guided by a guide plate provided at an angle of 45 degrees with respect to the conveying direction, and the conveyor changes its conveying direction toward the rear, where it receives the incoming carrots, conveys them diagonally upward, and releases them downward from the upper end.

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

[0061] Furthermore, only when the parking brake is activated by the parking lever 45 of the operating section B can the slide switch provided near the auxiliary work seat 23 be operated to operate the slide electric cylinder 39, thereby moving the sorting and conveying device 21 of the sorting and conveying section D to the right of the machine, allowing the rotating base to be rotated to the right and outward, and the lifting lever 43 to be used to lower the FIBC bag 22 into the field, thereby ensuring safety as the work of lowering the FIBC bag 22 into the field can only be performed when the machine is stopped.

[0062] In addition, when the sorting and conveying device 21 of the sorting and conveying section D is moving to the right of the machine body by operating the slide switch provided near the auxiliary work seat 23 to operate the slide electric cylinder 39, when the rotating base is rotated outward to the right, and when the lifting lever 43 is used to lower the FIBC bag 22 into the field, the work status can be displayed on the monitor of the operation panel 9 of the control section B and an alarm sound or an alarm voice (in various languages) that indicates the work status can be emitted, so that the operator seated in the control seat 8 of the control section B can recognize that an auxiliary operator is lowering the FIBC bag 22 into the field, and unforeseen circumstances such as inadvertently moving the machine forward can be avoided, thereby ensuring safety.

[0063] In addition, when the sorting and conveying device 21 is not positioned at the left end of the aircraft, even if the pilot seated in the pilot's seat 8 of the control section B attempts to move the aircraft forward, the aircraft will not start moving and an alarm will be sounded, ensuring safety.

[0064] With the movable conveyor 41 facing straight backward, the hanging hanger 24 hangs and supports the flexible container bag 22 by hooking the hook 29a of the hanging hanger 24 into the locking hole at the upper edge of the flexible container bag 22. At this time, the bottom of the flexible container bag 22 is supported by the placement table 25. [Explanation of symbols]
