[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, and the terms front, rear, left and right will be used.

[0013] <Overall structure> The carrot harvester is composed of a traveling section A that drives the machine, a control section B on which the operator rides, a harvesting section C that pulls carrots from 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 sorting and transporting section D that receives the carrots that fall from the stem and leaf cutting section and processes the stems and leaves remaining on the carrots in a remaining leaf processing section, a sorting and transporting section D that takes over the carrots from the remaining leaf processing section and transports them from one side of the machine to the other side, where an assistant operator sorts the carrots as they are transported, and a storage section E that stores 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 drive 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 frame 1, and multiple rollers 4 attached between the left and right drive sprockets 2, 2 and the left and right driven wheels 3, 3. The left and right drive sprockets 2, 2 of the left and right crawlers 6L, 6R are attached to left and right drive shafts extending on both the left and right sides from a transmission case to which engine power is transmitted, and the left and right crawlers 6L, 6R are attached to the machine frame 1 with a certain left-right gap 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 the forward / reverse movement and 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 is detachably attached to the other side (right side) of the control frame 7 of the aircraft body to protect a radiator (not shown) that cools the engine and take in cooling air, thereby forming a control section B.

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

[0018] <Harvesting Section C> Left and right driven pulleys 14a, 14a are rotatably attached to the front of the left and right pull-out frames 13, 13, and left and right drive pulleys 14b, 14b are attached to the rear of the machine. Left and right clamping conveyor belts 15, 15 for pulling 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 drive pulleys 14b, 14b. The left and right clamping conveyor belts 15, 15 are tensioned by multiple tension rollers 16, and the inner sides of the left and right clamping conveyor belts 15, 15 are pressed against each other to form a carrot pulling and transport path (pulling and transport passage) R. A rotating frame is attached above the machine frame 1 so as to be vertically rotatable about left and right horizontal axes as pivot points. A transmission case for transmitting driving force to the left and right drive pulleys 14b, 14b is attached to the rear end of the rotating frame so as to be vertically rotatable about the pivot point. The machine frame 1 and the rotary frame are connected by a lifting cylinder, and the lifting cylinder is attached so as to be operable by the control section B, thereby forming a drawing and conveying device 17.

[0019] Also provided in front of the pulling-out and conveying device 17 are a vertical pulling-up device 18 for pulling up the stems and leaves of the carrots, a horizontal pulling-up device 19 for scooping up the stems and leaves pulled up by the vertical pulling-up device 18, a weed-separating rod 20 provided in front of the horizontal pulling-up 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 S for loosening the soil on the left and right of the carrots buried in the soil by reciprocating vibrations using the driving force of the engine.

[0020] A tail cutting device for cutting the roots of carrots being transported by the pulling and transporting device 17 is attached below the pulling and transporting passage R, 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 the 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, thereby improving work efficiency.

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

[0023] The machine frame 1 and a rotating frame that can rotate freely up and down around the left and right horizontal axes as rotation fulcrums are connected by a lifting cylinder, and the lifting cylinder is extended and retracted by operating the lifting operation lever 11 on 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 starting end of the pulling and conveying of the harvesting unit C can be adjusted up and down and the position of the starting end of the pulling and conveying can be adjusted to match the appropriate pulling height for carrots growing in the field, preventing 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, which allows for smooth turning and improves work efficiency.

[0025] <Sorting and conveying section D> The sorting and conveying device 21 for sorting work in the sorting and conveying section D is arranged from the rear below the pulling and conveying device 17 in the harvesting section C toward the storage section E, where the flexible container bags 22, which are storage members for storing carrots, are located, and is composed of a chain conveyor with bars spaced at regular intervals that rotates with the driving force from the engine. Carrots conveyed by the pulling and conveying device 17 with their stems and leaves clamped, have their lower ends (slightly above the carrot's top) cut in the stem and leaf cutting section, causing the carrots to fall downward. The remaining leaf processing section receives the fallen carrots, processes the stems and leaves remaining on the carrots, and conveys them to the sorting and conveying section D. The sorting and conveying device 21 in the sorting and conveying section D then conveys the carrots from their left ends to the right (storage section E).

[0026] The sorting and conveying device 21 is also composed of a horizontal conveying conveyor 21a that is installed horizontally on the right side of the machine body from the rear lower part of the pulling and conveying device 17 in the harvesting section C, and a movable conveying conveyor 21b that takes over the harvested crops from the right end of the horizontal conveying conveyor 21a and conveys them diagonally upward and to the upper right to the storage section E.

[0027] The movable conveyor 21b has its left end, which takes over the harvested crops from the right end of the horizontal conveyor 21a, supported so as to be freely rotatable by a pivot shaft, and the right end side on the storage section E side moves up and down by the extension and contraction operation of the electric cylinder 21c for vertical movement, allowing the inclination angle to be changed.

[0028] An auxiliary work seat 23 is provided on the rear side of the movable transfer conveyor 21b, and a worker seated on the auxiliary work seat 23 takes out non-marketable carrots (small carrots or carrots with irregular shapes) from among the carrots sent by the movable transfer conveyor 21b, and sends only carrots with proper market value to the storage section E.

[0029] Furthermore, the worker seated on the auxiliary work seat 23 operates the foot-operated lift switch and processing switch to extend and retract the vertical movement electric cylinder 21c, thereby moving the right end of the movable transfer conveyor 21b up and down.

[0030] <Containment Unit E> The storage section E is located to the right of the sorting and conveying device 21 and is composed of a hanging hanger 25 that moves up and down and left and right by an operating arm 24 provided at the right end of the movable conveying conveyor 21b of the sorting and conveying device 21, and a loading table 26 on which the flexible container bag 22 suspended from the hanging hanger 25 is placed.

[0031] The movable conveyor 21b extends obliquely upward from its base at the left end to its upper right end. It rotates with the driving force of the engine, transporting carrots obliquely upward and releasing them downward from its upper end. The base of the movable conveyor 21b is pivotally supported by a pivot shaft, and the piston tip of an electric vertical movement cylinder 21c, whose base is pivotally supported on the machine frame 1, is connected to its midpoint.

[0032] That is, while an operator seated on the auxiliary work seat 23 depresses an up switch operated by the operator, the vertical movement electric cylinder 21c extends and rotates about the pivot shaft to raise the movable transfer conveyor 21b, and while an operator depresses a down switch, the vertical movement electric cylinder 21c contracts and rotates about the pivot shaft to lower the movable transfer conveyor 21b. When the operator operates a cross-directional operation lever 27 provided on the right end of the operation panel 9 (described later) to the right while descending into the field and facing the rear of the machine body, the vertical movement electric cylinder 21c extends and rotates about the pivot shaft to raise the movable transfer conveyor 21b, and when the operator operates the cross-directional operation lever 27 to the left, the vertical movement electric cylinder 21c contracts and rotates about the pivot shaft to lower the movable transfer conveyor 21b.

[0033] The hanging hanger 25 is moved up and down and left and right by an operating arm 24 provided at the right end of the movable transfer conveyor 21b.

[0034] The operating arm 24 is composed of a base arm 24a whose base is pivoted to the right end of the movable transport conveyor 21b so that it can rotate counterclockwise when viewed from behind but stops rotating clockwise at a predetermined position, and whose tip extends toward the upper right outside of the body, a rotating arm 24b pivoted to the tip of the base arm 24a so that it can rotate freely, and a rotating electric cylinder 24c which serves as a rotating actuator and is arranged between the base arm 24a and the rotating arm 24b.

[0035] The hanging hanger 25 is provided at the tip of the rotating arm 24b. Above the mounting table 26, four hooks 25a of the hanging hanger 25 are hooked onto locking holes in the upper edge of the flexible container bag 22, thereby hanging and supporting the flexible container bag 22.

[0036] A cross-directional operation lever 27 is provided at the right end of the operation panel 9, and when the operator descends into the field and operates it to the right while facing the rear of the machine body, the vertical movement electric cylinder 21c extends and the movable transport conveyor 21b rotates around the pivot axis to rise, and when operated to the left, the vertical movement electric cylinder 21c contracts and the movable transport conveyor 21b rotates around the pivot axis to fall, and when operated towards the rear of the machine body, the rotating electric cylinder 24c extends and the rotating arm 24b rotates around the pivot axis to open outward to the right, and when operated towards the front of the machine body, the rotating electric cylinder 24c contracts and the rotating arm 24b rotates around the pivot axis to close inside the machine body on the left.

[0037] If the movable transfer conveyor 21b is not in the uppermost position when the cross-directional control lever 27 is operated, the electric rotating cylinder 24c will not be actuated even if the cross-directional control lever 27 is actuated toward the rear of the machine, and the rotating arm 24b will not be rotated about the pivot shaft to open outward to the right. In other words, only when the movable transfer conveyor 21b is in the uppermost position can the cross-directional control lever 27 be actuated toward the rear of the machine, actuating the electric rotating cylinder 24c and rotating the rotating arm 24b about the pivot shaft to open outward to the right.

[0038] In addition, a load sensor 28 is provided on the platform 26, and only when the flexible container bag 22 hanging from the hanging hanger 25 is lifted and the bottom of the flexible container bag 22 moves away from the platform 26 (only when the load sensor 28 no longer detects the flexible container bag 22), the cross-directional operating lever 27 is operated toward the rear of the machine body to activate the rotating electric cylinder 24c, causing the rotating arm 24b to rotate around the pivot shaft and open outward to the right.

[0039] Furthermore, a photosensor 29 is provided at the right outer end of the platform 26 to detect the presence of an object above, and when the flexible container bag 22 hanging from the hanging hanger 25 is lifted and the rotating arm 24b rotates about the pivot shaft due to the operation of the rotating electric cylinder 24c, opens to the right outer side and moves to the right outer side of the body, if it does not detect that the flexible container bag 22 is not above the right outer end of the platform 26 (the flexible container bag 22 has moved to the right outer side of the right outer end of the platform 26), even if the cross-directional operation lever 27 is operated to the left to rotate the movable transfer conveyor 21b about the pivot shaft and lower it, the vertical movement electric cylinder 21c will not operate and the movable transfer conveyor 21b will not move lower. Therefore, it is possible to avoid the flexible container bag 22 accidentally coming into contact with the right outer end of the platform 26 when lowering the flexible container bag 22 hanging from the hanging hanger 25 into the field.

[0040] <Carrot harvesting work> First, as shown in FIG. 4, the cross-directional operation lever 27 is operated to move the movable transfer conveyor 21b to its lowest position with the rotating arm 24b closed inside the left machine body.

[0041] The hooks 25a of the hanging hanger 25 are hooked onto the locking holes at the upper edge of the flexible container bag 22, respectively, to hang the flexible container bag 22, and the bottom of the flexible container bag 22 is placed on the mounting table 26.

[0042] The operator seated in the driver's seat 8 then advances the carrot harvester, aligning the front end of the pulling-out conveying path R of the pulling-out conveying device 17 of the harvesting section C with the carrot rows in the field, then operates the lifting operation lever 11 to lower the harvesting section C, and turns on the digging clutch to drive each section and move forward. Then, the carrot stems and leaves are raked up by the weeding rod 20, vertical pulling device 18, and horizontal pulling device 19, and the carrot stems and leaves are clamped in the pulling-out conveying path R of the pulling-out conveying device 17, the left and right vibrating soiler S loosens the soil to the sides and below the carrots, and the carrots are clamped and pulled out by the pulling-out conveying device 17 and transported rearward and upward.

[0043] Carrots conveyed by the pulling and conveying device 17 with their stems and leaves clamped therein are cut at the lower ends of the stems and leaves (slightly above the carrot head) in the stem and leaf cutting section, and the carrots fall downward. The carrots that fall are received by the remaining leaf processing section, which processes the stems and leaves remaining on the carrots, and then the carrots are conveyed to the sorting and conveying section D. The carrots are then conveyed from the left end to the right (storage section E) by the movable conveyor 21b of the sorting and conveying section D.

[0044] Then, a worker seated on an auxiliary work seat 23 at the rear side of the movable transport conveyor 21b removes non-marketable carrots (small carrots or oddly shaped carrots) from the carrots sent by the movable transport conveyor 21b, and only the carrots with market value are sent to the storage section E.

[0045] The carrots sent to the right end by the movable transfer conveyor 21b drop into and are stored in the flexible container bags 22 hung from the hooks 25a of the hanging hangers 25 at the right end of the movable transfer conveyor 21b.

[0046] As the amount of carrots stored in the flexible container bag 22 increases, the worker seated on the auxiliary work seat 23 presses down on the lift switch to extend the vertical movement electric cylinder 21c, causing the movable transport conveyor 21b to rotate around the pivot shaft and gradually rise.

[0047] Then, as shown in FIG. 5, the movable transfer conveyor 21b is rotated about the pivot shaft and raised until the flexible container bag 22 is filled with carrots, and then the operator stops driving the machine and stops it.

[0048] The operator seated in the auxiliary work seat 23 leaves the auxiliary work seat 23, descends to the field, stands near the right end of the control panel 9, and operates the cross-directional control lever 27 while facing the rear of the machine body.

[0049] First, the cross-directional control lever 27 is operated to the right to extend the vertical movement electric cylinder 21c, raising the movable transfer conveyor 21b to its highest position, and lifting the flexible container bag 22 above the platform 26 as shown in FIG.

[0050] Then, the cross-directional operating lever 27 is operated toward the rear of the machine body to extend the rotating electric cylinder 24c, rotate the rotating arm 24b about the pivot shaft, and open it to the right and outward, as shown in Figure 7, and move the flexible container bag 22 to the right and outward side of the loading platform 26.

[0051] Then, the cross-directional control lever 27 is operated to the left to contract the vertical movement electric cylinder 21c, lowering the movable transfer conveyor 21b to its lowest position, and the flexible container bag 22 is lowered into the field as shown in FIG.

[0052] Then, the hooks 25a of the hanging hanger 25 are released from the locking holes on the upper edge of the flexible container bag 22, the cross-directional operation lever 27 is operated to return to the state shown in Figure 4, and the locking holes on the upper edge of the empty flexible container bag 22 are hooked onto the hooks 25a of the hanging hanger 25, respectively, to hang the flexible container bag 22 so that the bottom of the flexible container bag 22 is supported on the platform 26, and then the operator sits on the auxiliary work seat 23. Then, the various parts are driven to move the machine forward and resume harvesting work.

[0053] After the harvesting work is completed, as shown in Figure 9, the cross-directional operating lever 27 is operated to raise the movable transport conveyor 21b to its highest position, close the rotating arm 24b, and rotate the operating arm 24 around the pivot at the base of the base arm 24a and into the machine body to store it in place. The platform 26 is also rotated upward and inward around the pivot at the base to store it in place. When in the stored state, the width of the machine body is reduced, making it easier to drive on the road, load and unload onto a truck, or store in a barn, etc.

[0054] In summary, the hanging hanger 25 moves up and down and left and right by the operating arm 24 provided at the right end of the movable transport conveyor 21b, so that the flexible container bag 22 placed on the platform 26 while suspended from the hanging hanger 25 can be lifted above the platform 26 by the operating arm 24 and lowered into the field at a position to the right of the platform 26.Even if the flexible container bag 22 lowered into the field tilts or the machine body meanders slightly, the flexible container bag 22 can be prevented from coming into contact with the machine body, and good and appropriate harvesting work can be carried out.

[0055] <Other embodiments> (1) FIG. 10 shows a second embodiment, illustrating another example of the operating arm 24.

[0056] That is, the operating arm 24, whose base is pivotally supported on the movable conveying conveyor 21b, is composed of a right operating link 30 and an electric cylinder 31, whose base is pivotally supported on the movable conveying conveyor 21b, and an upper link 32, which is connected and pivoted to the upper ends of the right operating link 30 and the electric cylinder 31.

[0057] A hanging hanger 25 is attached to the tip of the upper link 32.

[0058] Therefore, when the electric cylinder 31 is operated, the flexible container bag 22 suspended from the suspension hanger 25 can be lowered into the field at a position on the right outer side of the loading platform 26.

[0059] (2) FIG. 11 shows a third embodiment, illustrating another example of the operating arm 24.

[0060] That is, the operating arm 24 is composed of a cylindrical body 33 fixed to the movable transfer conveyor 21b and an operating rod 34 that moves left and right inside the cylindrical body 33. A helical screw 34a is formed at the base of the operating rod 34 inserted into the cylindrical body 33, and when driven by an electric motor 35, a rotating ring 36 having an engaging protrusion that engages with the helical screw 34a rotates, causing the operating rod 34 to move left and right on the machine body.

[0061] A hanging hanger 25 is attached to the right end of the operating rod 34.

[0062] Therefore, when the electric motor 35 is operated, the flexible container bag 22 suspended from the hanging hanger 25 attached to the right end of the operating rod 34 of the operating arm 24 can be lowered into the field at a position to the right outside of the loading platform 26.

[0063] (3) FIG. 12 shows a fourth embodiment, illustrating another example of the operating arm 24.

[0064] That is, the operating arm 24 is composed of an electric cylinder 37 fixed to the movable transfer conveyor 21b and a link 38 provided at the tip of the electric cylinder 37. The hanging hanger 25 is attached to the tip of the link 38.

[0065] Therefore, when the electric cylinder 37 is extended, the flexible container bag 22 suspended from the suspension hanger 25 can be lowered into the field at a position on the right outer side of the loading platform 26. [Explanation of symbols]
