[0014] 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.

[0015] <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.

[0016] <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.

[0017] <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.

[0018] 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.

[0019] 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.

[0020] <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.

[0021] 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 S for loosening the soil on the left and right sides of the carrots buried in the soil by reciprocating vibrations provided by the driving force of the engine.

[0022] 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 passage R, thereby forming a harvesting section C.

[0023] 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.

[0024] In addition, since the carrots can be prevented from being damaged by contact with the left-right vibrating soy washer S or the like, the commercial value of the carrots is improved.

[0025] 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.

[0026] 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.

[0027] <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 carrots, 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).

[0028] In addition, the sorting and conveying device 21 is composed of a horizontal conveying conveyor 21a that is installed horizontally from the rear below of the extraction and conveying device 17 in the harvesting section C to the right side of the body, 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.

[0029] The movable transport conveyor 21b has its left end, which takes over the harvested crops from the right end of the horizontal transport conveyor 21a, supported so as to be freely rotatable on a pivot shaft, and the right end side on the storage section E side can be moved up and down by the extension and contraction operation of the vertical movement electric cylinder 21c, so that the inclination angle can be changed.

[0030] An auxiliary work seat 23 is provided on the rear side of the movable transport conveyor 21b, and a worker seated on the auxiliary work seat 23 removes non-marketable carrots (small carrots or carrots with irregular shapes) from the carrots transported by the movable transport conveyor 21b, and transports only carrots with proper market value to the storage section E.

[0031] Also, an operator seated on the auxiliary work seat 23 operates the foot-operated up switch and down switch to expand and contract the vertical movement electric cylinder 21c, thereby moving the right end side of the movable transfer conveyor 21b up and down.

[0032] <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 25 that moves up and down and left and right by an operating arm 24 as a moving device provided at the right end of the movable conveying conveyor 21b of the sorting and conveying device 21, and a loading platform 26 on which the flexi-con bag 22 hung from the hanging hanger 25 is placed.

[0033] The movable transfer conveyor 21b is provided diagonally upward from the base at the left end to the upper right end. That is, it rotates by the driving force from the engine to transfer the carrots diagonally upward and releases them downward from the upper end. The base of the movable transfer conveyor 21b is provided so as to be freely rotatable on a pivot shaft, and the piston tip of the vertical movement electric cylinder 21c, whose base is pivotally supported on the machine frame 1, is connected to the middle part of the movable transfer conveyor 21b.

[0034] That is, while the operator seated on the auxiliary work seat 23 depresses the up switch, the vertical movement electric cylinder 21c extends and rotates around the pivot shaft to rise, and while the operator depresses the down switch, the vertical movement electric cylinder 21c contracts and rotates around the pivot shaft to fall. When the operator descends to the field and operates a cross-directional operation lever 27 provided at the right end of the operation panel 9 (described later) to the right while facing the rear of the machine, the vertical movement electric cylinder 21c extends and rotates around the pivot shaft to rise, and when the operator operates the cross-directional operation lever 27 to the left, the vertical movement electric cylinder 21c contracts and rotates around the pivot shaft to fall.

[0035] The hanging hanger 25 moves up and down and left and right by an operating arm 24 provided at the right end of the movable transfer conveyor 21b.

[0036] 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 side extends toward the upper right outside of the body, a rotating arm 24b pivoted to the tip of the base arm 24a so as to be freely rotatable, and a rotating electric cylinder 24c disposed between the base arm 24a and the rotating arm 24b as a rotating actuator.

[0037] The hanging hanger 25 is provided at the tip of the rotating arm 24b. Above the placement 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 supporting the flexible container bag 22 in a suspending manner.

[0038] A cross-directional operation lever 27 is provided at the right end of the operation panel 9. When the operator descends into the field and faces the rear of the machine body, operating it to the right causes the up-down movement electric cylinder 21c to extend and the movable transport conveyor 21b to rotate about the pivot axis and rise, and when operating it to the left, the up-down movement electric cylinder 21c to retract and the movable transport conveyor 21b to rotate about the pivot axis and descend. When operating it toward the rear of the machine body, the pivoting electric cylinder 24c extends and the pivoting arm 24b rotates about the pivot axis to open outward to the right, and when operating it toward the front of the machine body, the pivoting electric cylinder 24c retracts and the pivoting arm 24b rotates about the pivot axis to close inside the machine body on the left.

[0039] If the movable transport conveyor 21b is not in the uppermost position when the cross-directional operation lever 27 is operated, the electric rotating cylinder 24c will not operate even if the cross-directional operation lever 27 is operated toward the rear of the machine body, and the rotating arm 24b will not rotate about the pivot shaft to open to the right outside. In other words, only when the movable transport conveyor 21b is in the uppermost position, the cross-directional operation lever 27 can be operated toward the rear of the machine body to operate the electric rotating cylinder 24c and rotate the rotating arm 24b about the pivot shaft to open to the right outside.

[0040] In addition, a load sensor 28 is provided on the mounting table 26, and only when the flexi-con bag 22 hung from the hanging hanger 25 is lifted and the bottom of the flexi-con bag 22 separates from the mounting table 26 (only when the load sensor 28 no longer detects the flexi-con bag 22), the cross-directional operating lever 27 is operated toward the rear of the body to activate the rotating electric cylinder 24c, causing the rotating arm 24b to rotate around the pivot axis and open to the right and outward.

[0041] In addition, a photosensor 29 is provided at the right outer end of the platform 26 for detecting the presence of an object above, and when the FIBC bag 22 hung from the hanging hanger 25 is lifted and the rotating arm 24b rotates about the pivot shaft by the operation of the rotating electric cylinder 24c to open to the right outer side and move to the right outer side of the machine body, if it is not detected that the FIBC bag 22 is not above the right outer end of the platform 26 (the FIBC bag 22 has moved to the right outer side beyond 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 transport conveyor 21b about the pivot shaft to lower it, the vertical movement electric cylinder 21c will not operate and the movable transport conveyor 21b will not move downward. Therefore, when the FIBC bag 22 hung from the hanging hanger 25 is lowered into the field, it is possible to avoid the FIBC bag 22 accidentally coming into contact with the right outer end of the platform 26.

[0042] Further, at the upper end of the cross-directional operation lever 27, a hook opening / closing switch 30 for opening and closing the four hooks 25a of the suspension hanger 25 is provided.

[0043] When the hook opening / closing switch 30 is pressed once, it activates the electromagnetic solenoid 31 provided at the pivot point of each hook 25a to close each hook 25a, and when pressed again, it activates the electromagnetic solenoid 31 to open each hook 25a. Note that when opening each hook 25a, in order to prevent erroneous operation, if the hook opening / closing switch 30 is not pressed for 0.5 seconds or more, the electromagnetic solenoid 31 will not be activated and each hook 25a will not be opened.

[0044] Furthermore, when a string hook 32 for fastening the string 22a of the flexible container bag 22 is provided at the upper end of the movable transfer conveyor 21b, the string hook 32 is opened and closed in the same manner by the hook opening / closing switch 30.

[0045] A red rotating light 33, which is an example of a warning light serving as a notification means, is provided at the highest position of the operating arm 24, that is, at the upper end of the base arm 24a.

[0046] The red rotating light 33 turns on and rotates when the load sensor 28 provided on the mounting table 26 detects that the FIBC bag 22 hung from the hanging hanger 25 has been lifted and the bottom of the FIBC bag 22 has left the mounting table 26 and when the rotating arm 24b pivoted to the tip of the base arm 24a of the operating arm 24 begins to open outward to the right by the electric rotating cylinder 24c, thereby notifying those in the vicinity that the operating arm 24 has operated to lower the FIBC bag 22 into the field. A potentiometer 34 is provided at the base of the rotating arm 24b pivoted to the tip of the base arm 24a and detects that the rotating arm 24b begins to open outward to the right by the electric rotating cylinder 24c.

[0047] For added safety, a horn can be sounded to warn drivers when the red rotating light 33 starts rotating. The horn sound is an intermittent sound that differs from the sound of a reversing buzzer or a warning sound sounded by the driver.

[0048] Therefore, when the operating arm 24 is operated to lower the flexible container bag 22 into the field, the red rotating light 33 rotates and lights up at the highest position of the operating arm 24, so that it is noticeable even in the evening and can properly notify the surroundings.

[0049] Here, the configuration of the mounting table 26 will be described in detail.

[0050] The mounting platform 26 is composed of a central flat plate 26a serving as a mounting surface extending to the right side through the through hole 1a provided at the right end of the body frame 1, a fore-aft movable frame 26b welded to the right end of the central flat plate 26a, a front plate 26c serving as a mounting surface provided in front of the central flat plate 26a and with both ends fixed to the right end of the body frame 1 and the movable frame 26b, and a rear plate 26d serving as a mounting surface provided on the rear side of the central flat plate 26a and with both ends fixed to the right end of the body frame 1 and the movable frame 26b.

[0051] The central flat plate 26a is configured so as to be slidable between a state in which it protrudes to the right by being inserted through a through hole 1a provided at the right end of the body frame 1, and a state in which it is retracted into the through hole 1a.

[0052] The front plate 26c and the rear plate 26d are provided with a joint portion 40 at the center position on the left and right, and can be freely changed between a flat state and a bent state bent upward.

[0053] Therefore, when the loading platform 26 grasps the movable frame 26b and pulls it out toward the right side of the body, the central flat plate 26a protrudes to the right as far as it can from the through hole 1a provided at the right end of the body frame 1, and the front plate 26c and rear plate 26d become flat, so that the central flat plate 26a, the front plate 26c and the rear plate 26d form a single planar loading surface for loading and supporting the FIBC bag 22 hung from the hanging hanger 25.

[0054] When the movable frame 26b is grasped and pushed toward the body frame 1, the central flat plate 26a retracts into the through hole 1a of the body frame 1, and the front plate 26c and the rear plate 26d become bent upward at the joint 40 located in the center of the left and right, opening up the lower bottom surface of the FIBC bag 22 hung from the hanging hanger 25, and by lowering the hanging hanger 25, the FIBC bag 22 can be lowered into the field as is without moving left and right or front and back.

[0055] <Carrot harvesting work> First, the loading platform 26 grasps the movable frame 26b and pulls it out toward the right side of the body so that the central flat plate 26a, the front plate 26c and the rear plate 26d form a single planar loading surface to receive the bottom of the FIBC bag 22 hung from the hanging hanger 25.

[0056] Then, 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.

[0057] The flexi-con bag 22 is suspended by hooking the locking holes at the upper edge of the flexi-con bag 22 onto each of the hooks 25a of the hanging hanger 25, and the hook opening / closing switch 30 of the cross-directional operating lever 27 is pressed to close each of the hooks 25a, so that the bottom of the flexi-con bag 22 is supported on the mounting table 26.

[0058] 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 the digging clutch "on" to drive each section to move forward. Then, the grazing rod 20, vertical lifting device 18 and horizontal lifting device 19 rake up the carrot stems and leaves, which are then clamped on 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 conveyed upward and rearward.

[0059] Then, carrots that have been transported with their stems and leaves clamped by pulling and transporting device 17 have their lower ends (slightly above the top of the carrot) cut 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 transporting section D. The carrots are then transported from the left end to the right (storage section E) by the movable transport conveyor 21b of sorting and transporting section D.

[0060] Then, a worker seated on an auxiliary work seat 23 on the rear side of the movable transport conveyor 21b removes non-marketable carrots (small carrots or carrots with irregular shapes) from the carrots conveyed by the movable transport conveyor 21b, and only the carrots with market value are sent to the storage section E.

[0061] The carrots sent to the right end by the movable transfer conveyor 21b drop 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.

[0062] As the amount of carrots stored in the flexi-con bag 22 increases, the worker seated on the auxiliary work seat 23 depresses the lift switch to extend the vertical movement electric cylinder 21c, causing the movable transport conveyor 21b to rotate about its pivot shaft and gradually rise.

[0063] Then, 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 the vehicle.

[0064] The operator seated in the auxiliary work seat 23 leaves the auxiliary work seat 23, descends into the field, stands near the right end of the control panel 9, and operates the cross-directional control lever 27 while facing toward the rear of the machine body.

[0065] First, the cross-directional control lever 27 is operated to the right to extend the vertical movement electric cylinder 21c, thereby raising the movable transfer conveyor 21b to its uppermost position, and lifting the flexible container bag 22 above the placement table 26.

[0066] Then, the cross-directional operating lever 27 is operated toward the rear of the machine body to extend the rotating electric cylinder 24c, causing the rotating arm 24b to rotate about the pivot shaft and open to the right outside, and the flexi-con bag 22 is moved to the right outside of the mounting table 26.

[0067] 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.

[0068] Then, the hook opening / closing switch 30 of the cross-directional operation lever 27 is pressed to open each hook 25a, and each hook 25a of the hanging hanger 25 is released from the locking hole at the upper end edge of the FIBC bag 22, and the cross-directional operation lever 27 is operated to return the movable transport conveyor 21b to the lowest position with the first rotating arm 24b closed inside the left machine body, and the locking holes at the upper end edge of the empty FIBC bag 22 are respectively hooked onto each hook 25a of the hanging hanger 25 to hang the FIBC bag 22 so that the bottom of the FIBC bag 22 is supported on the mounting table 26, and then the operator sits on the auxiliary work seat 23. Then, each section is driven to move the machine forward and the harvesting work is resumed.

[0069] Therefore, 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 flexi-con bag 22 placed on the mounting table 26 while hung from the hanging hanger 25 can be lifted above the mounting table 26 by the operating arm 24 and lowered into the field at a position on the right outer side of the mounting table 26.Even if the flexi-con bag 22 lowered into the field tilts or the body of the machine meanders slightly, it is possible to prevent the flexi-con bag 22 from coming into contact with the body of the machine, and good and appropriate harvesting work can be carried out.

[0070] If there is an obstacle such as a ridge or wall on the side of the ridge at the edge of the field and the flexi-con bag 22 cannot be lowered to the side of the machine body, the cross-directional operating lever 27 is operated to the right to extend the vertical movement electric cylinder 21c and raise the movable transport conveyor 21b to its uppermost position, thereby lifting the flexi-con bag 22 above the loading platform 26.

[0071] Then, the movable frame 26b of the mounting table 26 is grasped and pushed toward the body frame 1, causing the central flat plate 26a to retract into the through hole 1a of the body frame 1, and the front plate 26c and rear plate 26d are bent upward at the joint portion 40 at the center position on the left and right, thereby opening the lower part of the bottom of the FIBC bag 22 suspended from the hanging hanger 25.

[0072] 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.

[0073] Then, the hook opening / closing switch 30 of the cross-directional operation lever 27 is pressed to open each hook 25 a and release each hook 25 a of the hanging hanger 25 from the locking hole at the upper edge of the flexible container bag 22 .

[0074] In summary, when there is an obstacle such as a ridge or wall on the side of the ridge at the edge of the field and the flexi-con bag 22 cannot be lowered to the side of the machine, the movable frame 26b of the loading platform 26 is grasped and pushed toward the machine frame 1, the central plate 26a is retracted into the through hole 1a of the machine frame 1, and the front plate 26c and rear plate 26d are bent upward at the joint 40 located in the center of the left and right, thereby opening the lower part of the bottom of the flexi-con bag 22 suspended from the hanging hanger 25, so that the flexi-con bag 22 can be lowered directly into the field without moving left and right or front and back.

[0075] In addition, when the operating arm 24 is operated to lower the flexible container bag 22 into the field, the red rotating light 33 rotates and lights up at the highest position of the operating arm 24, so that it is noticeable even in the evening and can properly notify the surroundings, ensuring safety.

[0076] <Other embodiments> (1) FIGS. 6 and 7 show a second embodiment of the mounting table 26. FIG.

[0077] That is, the bases of the front swing arm 41F and the rear swing arm 41R are pivotally supported at the front and rear positions on the right end of the body frame 1.

[0078] A flat plate 26e serving as a mounting surface is pivotally supported at the front and rear ends of the front swing arm 41F and the rear swing arm 41R.

[0079] The front swing arm 41F and the rear swing arm 41R swing up and down to change the flat plate 26e between a horizontal state and a vertical state. The position is maintained in both states by a regulating device.

[0080] The inner end of the flat plate 26e is formed with a cut 42 which becomes deeper towards the center.

[0081] Therefore, the flat plate 26e of the mounting table 26 can be changed in position between a horizontal state in which the flexi-con bag 22 hung from the hanging hanger 25 is placed and supported, and a vertical state in which the lower side of the bottom surface of the flexi-con bag 22 hung from the hanging hanger 25 is open.

[0082] Since a cut 42 that is deeper toward the center is formed at the inner end of the flat plate 26e, the flat plate 26e can be prevented from coming into contact with the flexible container bag 22 when the flat plate 26e changes its position from a horizontal state to a vertical state.

[0083] (2) In the first embodiment, the central flat plate 26a is configured to be freely slidable between a state in which it protrudes to the right by being inserted through the through hole 1a provided at the right end of the body frame 1 and a state in which it is retracted into the through hole 1a, and the front plate 26c and the rear plate 26d are provided at the central left-right position with a joint portion 40 so that they can be freely changed between a flat state and a bent state bent upward. However, the front plate 26c and the rear plate 26d may be eliminated, and the entire mounting surface 26a of the mounting platform 26 may be configured to be freely slidable between a state in which it protrudes to the right by being inserted through the through hole 1a provided at the right end of the body frame 1 and a state in which it is retracted into the through hole 1a.

[0084] Also, the central flat plate 26a may be eliminated, and the entire mounting surfaces 26c, 26d of the mounting table 26 may be configured so that the joint portion 40 is provided at the center position on the left and right, allowing them to be freely changed between a flat state and a bent state bent upward.
