The upper ends of the drive shafts 295 of the pair of left and right pull-out drive pulleys 220L and 220R are rotatably supported by the bearing portions 271 of the pair of left and right pull-out transport frames 270L and 270R, and the respective drives are supported. The lower end of the shaft 295 is connected to a pair of left and right universal joints 6c and 6c, and the power branched in the left-right direction is transmitted from the front end of the transmission shaft 6b (see FIG. 1).

The lower ends of the pair of left and right universal joints 6c and 6c are bearing members provided at the upper and lower portions of the left and right ends of the transmission branch case 6d (see FIGS. 1 and 3) having a substantially T-shape in a plan view. It is connected to the tip of the vertical transmission shaft 6e (see FIGS. 1 and 3) rotatably supported by the vertical transmission shaft 6e. The transmission branch case 6d is connected to the front end of the transmission shaft case accommodating the transmission shaft 6b, and transmits the power branched in the left-right direction from the front end of the transmission shaft 6b in the vertical direction, such as the vertical transmission shaft 6e. It houses the transmission mechanism of.

Further, the pull-out driven pulley 230L on the left side and the holding roller group 240L on the left side can rotate with respect to the left holding force adjusting frame 280L which is repositionably attached to the lower surface of the tip portion of the pull-out transport frame 270L on the left side. It is attached to.

Further, the pull-out driven pulley 230R on the right side and the holding roller group 240R on the right side can rotate with respect to the right holding force adjusting frame 280R which is repositionably attached to the lower surface of the tip of the pull-out transport frame 270R on the right side. It is attached to.

Further, each of the pair of left and right holding force adjusting frames 280L and 280R is provided with long holes 281 long in the left-right direction at two front and rear positions, and within the range of the long holes 281 in the left-right direction (arrows in FIG. 5). After sliding to (see H) for positioning, the pair of left and right holding force adjusting frames 280L and 280R are fixed to the pair of left and right pull-out transport frames 270L and 270R by fastening members 282 such as bolts and nuts. is there.

As a result, the operator loosens the fastening member 282 and slides the pair of left and right holding force adjusting frames 280L and 280R in the left-right direction (see arrow H in FIG. 5) for positioning, and then the fastening member 282 left and right. By firmly fixing each of the pair of holding force adjusting frames 280L and 280R to the pair of left and right pull-out transport frames 270L and 270R, the distance G between the pair of left and right pull-out transport belts 210L and 210R (see FIG. 5) can be easily achieved. Can be adjusted to.

Therefore, the operator can easily adjust the pinching force on the upstream side of the transport path of the pull-out transport device 200 according to the thickness of the foliage W1 of the radish W and the presence or absence of morning dew during the working time, so that the pinching force is weak. Too much, the radish W is not pulled out from the field, and the trouble of pulling it out manually is prevented, and the holding force is too strong to crush the foliage W1, and the shoulder alignment device 300 takes over the foliage W1. It is possible to prevent the upper end W2b of the main body W2 of the radish W from being returned to the original hole in the field while remaining, so that the work of removing the upper end W2b of the main body W2 of the radish W in a later process. Does not occur.

Further, by loosening the fastening member 282 and sliding each of the pair of left and right holding force adjusting frames 280L and 280R, the holding force adjustment operation on the upstream side of the transport path of the pull-out transport device 200 can be easily performed. Because it can be done, work efficiency is improved.

Instead of the configuration in which the holding force of the pull-out transport device 200 is adjusted by using the fastening member 282 described above, for example, a lever mechanism is used for radish for raw consumption, for processing, for example, radish for oden, and for pickles. The radish may be configured to switch the holding force in three stages with one touch.

Next, the four sandwiching rollers constituting the pair of left and right sandwiching roller groups 240L and 240R will be described with reference to FIGS. 6A and 6B.

FIG. 6A is a schematic view for explaining a two-stage roller member 241a among the four sandwiching rollers constituting the pair of left and right sandwiching roller groups 240L and 240R, and is a sectional view taken along line EE in FIG. It is an arrow view. Further, FIG. 6B is a schematic view for explaining a one-stage roller member 241b among the four holding rollers constituting the pair of left and right holding roller groups 240L and 240R, and is a schematic view taken along the line FF in FIG. It is a cross-sectional view.

As shown in FIG. 5, the four holding rollers constituting the pair of left and right holding roller groups 240L and 240R mounted on the pair of left and right holding force adjusting frames 280L and 280R are close to the pair of left and right pull-out driven pulleys 230L and 230R. There is one two-stage roller member A241a (see FIG. 6A), then one one-stage roller member 241b (see FIG. 6B), and then a two-stage roller member 241a. (See FIG. 6A) are arranged respectively (see FIGS. 1 and 5).

As shown in FIG. 6A, the two-stage roller member 241a is rotatably attached to the long shaft 241a1 by the upper and lower two-stage rollers that come into contact with the inner wall surfaces of the pair of left and right pull-out transport belts 210L and 210R. The rib-shaped protrusions 211 protruding inward from the inner wall surface of the pair of left and right pull-out transport belts 210L and 210R are inserted into the gaps between the upper and lower two-stage rollers, so that the pressing force of the rollers is applied to the belts. It is a configuration that is surely transmitted to the side.

As shown in FIG. 6B, in the one-stage roller member 241b, an upper one-stage roller that comes into contact with the inner wall surfaces of the pair of left and right pull-out transport belts 210L and 210R is rotatably attached to the short shaft 241b1. A roller on the upper stage is arranged on the upper side of the rib-shaped protrusion 211 protruding inward from the inner wall surface of the pair of left and right pull-out transport belts 210L and 210R, so that the pressing force is applied to the belt side by the upper roller. It is a configuration that secures a space under the roller while transmitting to.

Further, since the one-stage roller member 241b is arranged corresponding to the position where the foliage portion W1 of the radish W is taken over from the pull-out transfer device 200 to the shoulder alignment device 300, the one-stage roller member on the bottom surface side of the pull-out transfer device 200 is arranged. Since the front ends of the pair of left and right shoulder alignment belts 310L and 310R of the shoulder alignment device 300 can be inserted and arranged in the space of 241b (see FIG. 6B), the shoulder alignment device 200 and the shoulder alignment device 200 can be arranged. The gap with the device 300 can be shortened, and the foliage portion W1 can be reliably taken over.

As a result, the two-stage roller member 241a is brought into contact with both sides of the rib-shaped protrusions 211 of the pair of left and right pull-out transport belts 210L and 210R to strengthen the holding force, thereby losing the reaction force when pulling out the radish W and holding the radish. Since it is possible to prevent the radish W from being released, the radish W can be reliably pulled out from the field.

Further, in the pair of left and right pull-out transport belts 210L and 210R, the front end portion of the shoulder alignment device 300 is arranged adjacent to the lower roller-less portion, and the foliage portion W1 is sandwiched by the one-stage roller member 241b via the belt. Therefore, it is possible to prevent the foliage portion W1 from falling off when the shoulder alignment device 300 takes over.

Further, on the pull-out transport frame 270L on the left side, a first tension roller 250L on the left side, a second tension roller 251L on the left side, and a third tension roller 252L on the left side are rotatably supported at one end of each.

The 251b and the third rotation arm 252b are rotatably attached around the first rotation fulcrum 250c, the second rotation fulcrum 251c, and the third rotation fulcrum 252c.

As a result, the rear ends of the first rotating arm 250b, the second rotating arm 251b, and the third rotating arm 252b are fixed to the side surface of the left side of the pull-out transport frame 270L. Due to the elastic contraction force of the first tension spring 250a, the second tension spring 251a, and the third tension spring 252a, an urging force that always tries to rotate clockwise is exerted in a plan view. Due to the urging force, the first tension roller 250L on the left side, the second tension roller 251L on the left side, and the third tension roller 252L on the left side press the inner peripheral surfaces of the pull-out transfer belt 210L on the left side with different pressing pressures. It is a composition.

That is, in the present embodiment, the pressing force by the first tension roller 250L on the left side, the second tension roller 251L on the left side, and the third tension roller 252L on the left side becomes weaker from the upstream side to the downstream side of the transport path. As such, the elastic forces of the first tension spring 250a, the second tension spring 251a, and the third tension spring 252a are adjusted in advance.

As for the pull-out transport frame 270R on the right side, the first rotation arm 250b, the second rotation arm 251b, and the third rotation arm 252b rotate first, as in the case of the pull-out transport frame 270L on the left side described above. It is rotatably attached around a fulcrum 250c, a second rotation fulcrum 251c, and a third rotation fulcrum 252c.

As a result, the first tension roller 250R on the right side, the second tension roller 251R on the right side, and the third tension roller 252R on the right side gradually weaken the inner peripheral surface of the pull-out transport belt 210R on the right side in the order described.

The outer peripheral portion is set so as to overlap below the transport path formed between the pair of left and right shoulder-aligned belts 310L and 310R in a plan view.

Further, the height of the boss portion 511 provided on the central axis of the upper surface of the pair of left and right disk-shaped body cutting rotary blades 510L and 510R is such that the pair of left and right body cutting rotary blades 510L and 510R have the rotating shafts 621 and 621. On the other hand, the height is set so as not to interfere with the lower surfaces of the pair of left and right shoulder-aligned belts 310L and 310R in a state of being inserted and connected by spline connection.

Further, a disk-shaped or cylindrical spacer having a predetermined thickness (not shown) that can be inserted into the rotating shafts 621 and 621 of the pair of left and right second sprockets 620L and 620R is provided. After inserting one or more of the spacers into the rotating shafts 621 and 621, a pair of left and right body cutting rotary blades are provided to the rotating shafts 621 and 621 protruding from the lower end of the spacer via the boss portions 511 and 511. The configuration is such that 510L and 510R can be spline-connected.

Further, by providing a pair of left and right rotating blades 510L and 510R, the upper end portion W2b of the radish W can be sandwiched from the left and right, so that the upper end portion W2b of the radish W can be completely cut and the field V can be used. The cut surface of the pulled out radish W is beautifully finished.

Further, the spacer can be detachably attached between the upper surface of the boss portions 511 and 511 of the pair of left and right disk-shaped body cutting rotary blades 510L and 510R and the lower surfaces of the pair of left and right second sprockets 620L and 620R. As a result, the cutting position of the upper end portion W2b of the main body portion W2 of the radish W can be changed, so that the cutting position can be realized according to the size of the radish and the conditions at the time of shipment, and the work efficiency is improved.

Further, on the upper surface of the pair of left and right body cutting rotary blades 510L and 510R, a boss (not shown) having a predetermined height is provided at the center thereof.

The support portions 331 and 331 are firmly fixed to the pair of left and right shoulder alignment stays 370L and 370R.

Furthermore, the operator loosens the fastening member 343 and gradually narrows the belt spacing of the transport path from the upstream side to the downstream side, and in a plan view, the body cutting device 500 (see FIGS. 1 and 7). The minimum dimension is the belt spacing J2 (see FIG. 7) at the position where the pair of left and right shoulder-aligned second rollers 350L and 350R oppose each other, which roughly corresponds to the position where the upper end portion W2b of the main body portion W2 of the radish W is started to be cut. The pair of left and right belt spacing first adjusting plates 341L and 341R, and the pair of left and right belt spacing second adjusting plates 351L and 351R on the downstream side thereof are individually placed in the left-right direction (arrows in FIG. 7). After sliding to (see H) and positioning, the pair of left and right belt spacing first adjusting plates 341L and 341R and the pair of left and right belt spacing second adjusting plates 351L and 351R are respectively moved by the respective fastening members 343. By firmly fixing to the pair of left and right shoulder alignment stays 370L and 370R, the distance between the pair of left and right shoulder alignment belts 310L and 310R J1 to J2 (see FIG. 7) can be easily adjusted.

In the present embodiment, the belt spacing at the position where the pair of left and right shoulder-aligned third rollers 380L and 380R oppose, and the belt spacing at the position where the pair of left and right shoulder-aligned fourth rollers 390L and 390R oppose are also described above. It is set to be the same as the interval J2.

Therefore, according to the above configuration, the operator can perform the pair of left and right driven pulley support portions 331, 331, the pair of left and right belt spacing first adjusting plates 341L and 341R, and the pair of left and right belt spacing second adjustments on the downstream side thereof. The plates 351L, 351R, etc. can be individually slid and moved in the left-right direction (see arrow H in FIG. 7) for positioning, and can be firmly fixed to the pair of left-right shoulder-aligned stays 370L and 370R. The width of the passage formed by the shoulder-aligned belts 310L and 310R (see reference numerals J1 and J2 in FIG. 7) is widely adjusted, for example, when the diameter of the large-diameter large rootstock for oden is 20 mm to 60 mm, and the pickles are pickled. When the diameter of the large rhizome is 10 mm to 40 mm, it can be adjusted narrowly.

Further, the single foliage rotary blade 410 of the foliage cutting device 400 described above is attached to a rotating shaft 721 protruding upward from the second sprocket 720 for the foliage cutting device described later, which is housed in the transmission case 8L on the left side. On the other hand, it is detachably inserted and connected by a spline connection, and the mounting height of the single foliage rotary blade 410 can be changed by using the same spacer or the like as in the case of the body cutting device 500 described above. Has been done.

Further, the cutting guide bar 420 of the foliage cutting device 400 described above has a substantially inverted L shape in a side view, and the lower end portion thereof is welded and fixed to the side surface of the shoulder alignment stay 370R on the right side. The tip end side of the upper end portion is located above the rotary blade 410 so as not to interfere with the single foliage rotary blade 410, and is arranged at a position overlapping the outer peripheral portion of the rotary blade 410 in a plan view. (See FIG. 7).

Next, the upper end portion discharge guide 800, which has basically the same structure as the upper foliage discharge guide 291 (see FIGS. 1 and 2), which is a rod-shaped member having a circular cross section, will be described.

That is, at the rear end of the shoulder alignment device 300, the upper end portion W2b of the main body portion W2 cut by the body portion cutting device 500 is pulled out and conveyed through the rear side of the outer peripheral edge portion of the shoulder alignment drive pulley 320R on the right side. Discharge at the upper end of the main body at a position away from the radish W pulled out by the device 200 so as to discharge toward the rear from the rear wheel drive shaft 3Ra (see FIG. 2) of the right rear wheel 3R in a plan view. A guide 800 is provided.

As shown in FIGS. 2 and 7, the upper end portion discharge guide 800 of the main body is curved in a substantially U-shape in a plan view, and the curved portion is a shoulder on the right side from the exit side of the transport path of the shoulder alignment device 300. It is arranged above the shoulder alignment drive pulley 320R on the right side so as to be along the rear side of the outer peripheral edge portion of the alignment drive pulley 320R.

Specifically, the base 801 of the main body upper end discharge guide 800 is detachably fixed to the outer surface on the right side of the transmission case 8L on the left side.

The shoulder-aligned outlet star wheel (not shown) having the same configuration as the pull-out outlet star foil 293 of the foliage discharge member 290 described above is provided on the upper surface of the shoulder-aligned drive pulley 320R on the right side and the lower surface of the transmission case 8R on the right side. It may be detachably attached to the shoulder alignment drive shaft 321 of the shoulder alignment drive pulley 320R on the right side. As a result, the foliage portion remaining on the upper end portion W2b of the main body portion W2 cut by the body portion cutting device 500 is more reliable with the uneven portion of the outer peripheral edge portion of the shoulder alignment outlet star wheel and the upper end portion discharge guide 800 of the main body. It is held by the rear wheel 3R on the right side and discharged toward the rear from the rear wheel drive shaft 3Ra.

As a result, the portion cut by the body cutting device 500 and discharged by the upper end discharge guide 800 of the main body falls to a place away from the position of the radish returned to the original hole, which hinders the collection of the radish. There is no such thing, and the efficiency of collection work is improved.

In addition, the rear wheels 3L and 3R step on the discharged portion to disturb the working posture of the machine body, the pull-out transfer device 200 fails to pull out the radish, and the cut surface on the upper end side of the main body becomes rough, which increases the commercial value. It is prevented from dropping.

The main body upper end discharge guide 800 of the present embodiment corresponds to an example of the main body upper end discharge guide member of the present invention.

Next, the upper end portion W2b of the main body portion W2 of the radish W is cut by the body cutting device 500, and the radish tilting that contacts the back surface side of the radish returned to the original hole of the field V and tilts the radish forward. The device 900 will be described with reference to FIG.

The radish tilting device 900 has, as shown in FIG.
1. 1. Each time it comes into contact with the back side of the radish returned to the original hole, the radish is tilted forward, and the contact member 910 that temporarily moves backward due to the counterforce from the tilted radish.
2. 2. A counter switch 920 that detects the number of times the contact member 910 moves backward each time the contact member 910 comes into contact with the radish.
Is equipped with.

The contact member 910 is a rectangular plate-shaped member that is long in the left-right and lateral directions when viewed from the front, and forms a resin member forming an upper end portion of the plate-shaped member and a lower portion connected to the resin member. It is integrally composed of a rubber member.

Further, the upper end portion of the contact member 910 is rotatably attached to a radish tilting device mounting stay 930 bridged and fixed to the lower surface portions of the pair of left and right main frames 9L and 9R.

The location of the contact member 910 is substantially below the pair of left and right shoulder-aligned drive pulleys 320L and 320R in a side view.

As a result, the rubber member portion of the contact member 910 tilts the radish forward by pushing the radish, and the resin member portion connected to the rubber member moves rearward to move the counter switch 920. By pushing the protrusion, the number of radishes pulled out by the pull-out transfer device 200 can be counted and displayed.

Therefore, since the worker can easily grasp the number of collected radishes by reading the numerical value displayed on the counter switch 920, the worker does not have to count the collected radishes, and the work efficiency is improved and the worker's work efficiency is improved. Labor can be reduced.

The radish tilting device 900 of the present embodiment corresponds to an example of the crop tilting device of the present invention. Further, the contact member 910 of the present embodiment corresponds to an example of the crop contact member of the present invention, and the counter switch 920 of the present embodiment corresponds to an example of the number of times detection member of the present invention.

According to the above configuration, by appropriately performing the left-right direction (see the arrow H in FIG. 5) of the pair of left and right holding roller groups 240L and 240R of the pull-out transport device 200, the pull-out transport device 200 can be used when the radish W is pulled out. On the other hand, in the range where the largest load is applied, the pressing force of each holding roller is surely transmitted to the pair of left and right pull-out transport belts 210L and 210R, and the foliage W1 of the radish W is firmly held and moved diagonally upward and backward. As a result, the main body W2 of the radish W is surely pulled out from the field V.

After that, as the belt is conveyed from the pair of left and right first tension rollers 250L and 250R toward the third tension rollers 252L and 252R, the holding force of the belt by each tension roller of the pull-out transfer device 200 becomes weaker.

On the other hand, below that, the belt spacing J1 (see FIG. 7) on the entrance side of the transport path in the shoulder alignment device 300 arranged horizontally with respect to the surface of the field V is the shoulder portion W2a at the upper end of the radish W. Is set so wide that it does not pass upward, and is configured so as not to hinder the upward movement of the radish W by the pull-out transport device 200, but the belt spacing of the transport path of the shoulder alignment device 300 is as described above. It gradually narrows from the upstream side to the downstream side, and the holding force of the pair of left and right shoulder-aligned belts 310L and 310R gradually increases.

As a result, as shown in FIG. 1, the foliage portion W1 of the radish W is moved diagonally backward and upward along the transport direction A (see FIG. 5) of the pull-out transport device 200, but the main body portion W2 The shoulder portion W2a at the upper end of the shoulder alignment device 300 is restricted from moving upward by abutting on the lower surfaces 310La and 310Ra (see FIG. 6B) of the pair of left and right shoulder alignment belts 310L and 310R of the shoulder alignment device 300. .. When the shoulder portion W2a of the radish W comes into contact with the lower surfaces 310La and 310Ra of the pair of left and right shoulder alignment belts 310L and 310R, the gripping force of the pull-out transport device 200 is weak and the gripping force of the shoulder alignment device 300 is strong. Therefore, the upward movement of the shoulder portion W2a is restricted on the downstream side from the contact position, and the upper end portion W2b of the main body portion W2 of the radish W is cut by the body cutting device 500 (see FIGS. 1 and 7). In the vicinity of the starting position, the positions of the shoulder portion W2a of the radish W in the height direction are aligned.

As a result, the shoulder alignment device 300 aligns the shoulder portion W2a of the radish W, so that the body cutting device 500 reliably cuts the upper end portion W2b of the main body portion W2 of the radish W of the radish W at a desired position. Moreover, the foliage portion W1 of the radish W can be cut at a desired position by the foliage cutting device 400. Further, since the cutting of the main body W2 is started before the cutting of the foliage W1 of the radish W is started, when the main body W2 is cut, the foliage W1 is pulled out and conveyed to the shoulder alignment device 200. Since the main body W2 is firmly held in the upper and lower positions by the 300, for example, it is possible to prevent the main body W2 from shifting forward and being cut diagonally at the time of cutting, so that it is possible to prevent the cutting position from shifting and cutting failure. The surface is also beautifully finished.

After the upper end portion W2b of the main body portion W2 of the radish W is cut, the main body portion W2 of the radish W falls and returns to the original hole (see FIG. 1). Therefore, it is not necessary to cut the upper end portion W2b of the main body portion W2 of the radish W in the post-processing, and the work efficiency can be improved and the labor can be reduced.

In addition, the radish tilting device 900 can tilt the radish returned to the hole in the field forward, and the hole in the place where the radish was vegetated becomes large, so that the operator can easily lift the radish when collecting it. As a result, work efficiency is improved.

Further, by providing the counter switch 920, the operator does not have to count the number of collected radishes.

Further, since the foliage portion W1 cut by the foliage cutting device 400 does not have the upper end portion W2b of the radish W, the upper foliage discharge guide 291 and the lower foliage discharge from the outlet portion of the transport path of the pull-out transport device 200. Guided by the guide 292, it is smoothly discharged to the right side of the aircraft without being caught.

In addition, by making the foliage discharge member 290 removable and changing the discharge direction of the cut foliage, the cut foliage is cut according to the cultivation position of the radish and the necessity of collecting the cut foliage. Since the discharge position of the part can be changed, it is prevented that the foliage part that has been discharged and dropped covers the radish and interferes with the recovery work of the radish, and the work efficiency is improved.

Further, in the upper end portion W2b of the radish W cut by the body portion cutting device 500, the foliage portion left there is the shoulder on the right side from the outlet side of the transport path of the shoulder alignment device 300 by the main body upper end portion discharge guide 800. By being conveyed along the rear side of the outer peripheral edge portion of the aligned drive pulley 320R, it is discharged toward the rear from the rear wheel drive shaft 3Ra of the right rear wheel 3R.

Further, the shoulder alignment drive shafts 321 and 321 of the pair of left and right shoulder alignment drive pulleys 320L and 320R have a pair of left and right shoulder cutting rotary blades with reference to the transport direction of the shoulder alignment device 300 (see arrow A'in FIG. 7). By being arranged on the downstream side of the respective boss portions 511 and 511 of the 510L and 510R, the load generated when the pair of left and right body cutting rotary blades 510L and 510 cut the radish is applied to the pair of left and right shoulder-aligned drive pulleys 320L. , 320R shoulder alignment drive shafts 321 and 321 can be prevented from being directly received, so that the transport operation by the pair of left and right shoulder alignment belts 310L and 310R is prevented from becoming unstable, and the cutting position of the main body of the radish and It prevents the cutting position of the foliage from being disturbed and preventing the radish from being pulled out sufficiently.

Further, according to the above configuration, the outlet side of the transport path of the shoulder alignment device 300 can be positioned on the rear side of the machine body, that is, on the rear side of the pair of left and right rear wheels 3L and 3R. It is prevented that the upper end portion of the discharged radish falls on the path of the pair of left and right rear wheels 3L and 3R.

The pair of left and right shoulder alignment belts 310L and 310R of the present embodiment correspond to an example of the pair of left and right endless alignment transport belts of the present invention. Further, the pair of left and right shoulder alignment drive pulleys 320L and 320R of the present embodiment correspond to an example of the pair of left and right alignment drive pulleys of the present invention.

Further, the single foliage rotary blade 410 of the present embodiment corresponds to an example of the leaf cutting blade of the present invention. Further, the pair of left and right body cutting rotary blades 510L and 510R of the present embodiment corresponds to an example of the pair of left and right main body cutting blades of the present invention.

Next, using FIG. 7, a pair of left and right first chain transmission mechanisms that transmit the driving force from the engine 4 to the pair of left and right shoulder-aligned drive pulleys 320L and 320R and the pair of left and right body cutting rotary blades 510L and 510R. The 600L and 600R will be described, and the second chain transmission mechanism 700 that transmits the driving force from the engine 4 to the single foliage rotary blade 410 will be described.

The pair of left and right first chain transmission mechanisms 600L and 600R are housed in the transmission cases 8L and 8R arranged on the left and right, and the second chain transmission mechanism 700 is housed in the transmission case 8L arranged on the left side. ing.

As shown in FIG. 7, the pair of left and right first chain transmission mechanisms 600L and 600R are
1. 1. A pair of left and right powers branched in the left-right direction from the front end of the transmission shaft 6b (see FIG. 7) are transmitted via vertical transmission shafts 6e and 6e vertically arranged at both left and right ends of the transmission branch case 6d. 1 sprocket 610L, 610R,
2. 2. It has rotating shafts 621 and 621 that are arranged in front of the pair of left and right first sprockets 610L and 610R and extend downward, and each of the rotating shafts 621 and 621 has a pair of left and right body cutting rotary blades 510L and 510R. A pair of left and right second sprockets 620L, 620R that are detachably spline-connected,
3. 3. A pair of left and right first transmission chains 630L and 630R around which a pair of left and right first sprockets 610L and 610R and a pair of left and right second sprockets 620L and 620R are wound.
Is equipped with.

Further, the second chain transmission mechanism 700 has, as shown in FIG. 7,

The power branched to the left from the front end of the transmission shaft 6b (see FIG. 7) is transmitted via the vertical transmission shaft 6e arranged perpendicularly to the right end of the transmission branch case 6d. The first sprocket 710 for the foliage cutting device, which is arranged coaxially with the sprocket 610L and directly above the first sprocket 610L,
2. 2. A second sprocket for a foliage cutting device that is arranged below a single foliage rotary blade 410, has a rotary shaft extending upward, and the foliage rotary blade 410 is detachably splined to the rotary shaft. 720 and
3. 3. A second transmission chain 730 around which the first sprocket 710 for the foliage cutting device and the second sprocket 720 for the foliage cutting device are wound.
Is equipped with.

Further, since the space is secured below the body cutting device 500 by the above configuration, the upper end W2b is cut and comes into contact with the radish W returned to the original hole of the field V, and the main body W2 is damaged. There is no such thing, and the decrease in commercial value is prevented.

Further, since the rubber member portion of the contact member 910 that pushes the main body portion W2 of the radish has elasticity, the main body portion W2 of the radish is not damaged and the commercial value is prevented from being lowered. ..

Further, by arranging the pair of left and right shoulder alignment belts 310L and 310R so as to be substantially horizontal with respect to the field scene, when aligning the positions of the upper end shoulder portion W2a of the main body portion W2 of the radish W, The shoulder portion W2a at the upper end of the main body portion W2 of the radish W abuts on the lower surfaces 310La and 310Ra of the pair of left and right shoulder alignment belts 310L and 310R, respectively, and it is possible to prevent the radish W from being pulled upward. Prevents the belt from flipping over and coming off.

Further, by providing the pull-out transport device 200 with a pair of left and right holding roller groups 240L and 240R, the pinching force near the entrance of the transport path of the pull-out transport device 200 becomes stronger, so that even a heavy radish can be firmly held. Since it can be pinched, it can be reliably pulled out from the field, and the efficiency of radish recovery work is improved.

Further, as shown in FIG. 3, each of the pair of left and right pull-out transfer device covers 202L and 202R described above is configured to be divided into front and rear parts in the vicinity of the center in a plan view.

That is, the left side pull-out transport device cover 202L is composed of the left front side cover 202La and the left rear side cover 202Lb, and the right side pull-out transport device cover 202R is composed of the right front side cover 202Ra and the right rear side cover 202Rb. Has been done.

Thereby, for example, when adjusting the right side of the pull-out drive pulley 220R, the necessary work can be performed by removing only the right rear side cover 202Rb of the right side pull-out transport device cover 202R, and for example, the left side. When adjusting the pull-out driven pulley 230L side, the necessary work can be performed by removing only the left front side cover 202La of the left side pull-out transport device cover 202L, so that the work efficiency is improved.

Further, as shown in FIG. 1, each of the pair of left and right pull-out transport device covers 202L and 202R sandwiches and conveys the foliage portion W1 of the radish W in the outer peripheral side surfaces of the pair of left and right pull-out transport belts 210L and 210R. A pair of left and right transport belt cover overhangs 202LL that cover the portion that constitutes the transport path, the peripheral portion of the pair of left and right pull-out drive pulleys 220L and 220R, and the portion excluding the peripheral portion of the pair of left and right pull-out driven pulleys 230L and 230R. , 202RR.

Below the foliage discharge member 290, both side back covers 204 that cover the rear end side of the pull-out transport device 200 in a plan view are detachably fixed with bolts and nuts.

As a result, it is possible to prevent the cut foliage W1 from falling onto the foliage cutting device 400 and causing cutting defects.

Further, as a result, the foliage rotary blade 410 and the pair of left and right trunk cutting rotary blades 510L and 510R can be covered, so that the safety is improved.

In the above embodiment, the portion of the blade edge on the upstream side of the pair of left and right body cutting rotary blades 510L and 510R on the transport path formed by the pair of left and right shoulder alignment belts 310L and 310R in a plan view is formed. , The case where the single foliage rotary blade 410 is configured to be located on the upstream side of the blade edge on the upstream side of the portion existing on the transport path in a plan view has been described, but the present invention is not limited to this. For example, in a plan view of a pair of left and right body cutting rotary blades 510L and 510R, the portion of the cutting edge on the upstream side of the portion existing on the transport path formed by the pair of left and right shoulder alignment belts 310L and 310R has a single foliage rotation. The blade 410 may be configured to be located on the downstream side of the blade edge portion on the upstream side of the portion existing on the transport path in a plan view. Even in this case, by providing a body cutting device that cuts the upper end of the main body of the radish, it is not necessary to cut the upper end of the main body of the radish in post-processing, which improves work efficiency and labor. Reduction is planned.

Further, in the above embodiment, the pair of left and right shoulder-aligning rotary blades 510L and 510R have their respective boss portions 511 and 511, and the pair of left and right shoulder-aligning drive pulleys 320L and 320R have their respective shoulder-aligned drive shafts 321 and 321. The case where they are arranged at different positions in a plan view has been described, but the present invention is not limited to this. For example, these boss portions 511 and 511 and the shoulder alignment drive shafts 321 and 321 are coaxially connected by spline coupling so as to be detachably connected. It may be an arranged configuration. A configuration example in this case is shown in FIG.

FIG. 8 is a schematic plan view showing a second shoulder alignment device 1300, a pair of left and right trunk cutting rotary blades 510L, 510R, and a second foliage rotary blade 1410 as configuration examples different from the configuration example shown in FIG. .. The same components as those shown in FIG. 7 are designated by the same reference numerals, and the description thereof will be omitted.

In the configuration example shown in FIG. 8, the cutting edge of the pair of left and right body cutting rotary blades 510L and 510R on the upstream side of the portion existing on the transport path formed by the pair of left and right second shoulder alignment belts 1310L and 1310R in a plan view. The portion is configured to be located on the downstream side of the portion of the cutting edge on the upstream side of the portion existing on the transport path in a plan view of the single second foliage rotary blade 1410.

Further, in order to prevent the foliage portion W1 from being pushed by the second foliage rotary blade 1410 and escaping, the foliage portion W1 is guided to the second foliage rotary blade 1410 side, and is a substantially inverted L-shaped third in a side view. 2 A cutting guide bar 1420 is provided.

Further, the pair of left and right body cutting rotary blades 510L and 510R are spline-connected to the second shoulder alignment drive shafts 1321 and 1321 extending downward from the pair of left and right second shoulder alignment drive pulleys 1320L and 1320R via a boss portion. It is detachably inserted and connected from below. Further, in the case of the configuration of FIG. 8, the pair of left and right second sprockets 620L and 620R housed in the left and right transmission cases 8L and 8R have a pair of left and right second shoulders on the rotating shafts 621 and 621 extending downward. Alignment drive pulleys 1320L and 1320R are detachably inserted and connected by spline connection.

Further, in the case of the configuration of FIG. 8, the second sprocket 1720 for the second foliage cutting device housed in the left transmission case 8L is arranged in front of the left second sprocket 620L in a plan view.

Further, the single second foliage rotary blade 1410 arranged above the left transmission case 8L splines with respect to the second rotary shaft 1721 protruding upward from the second sprocket 1720 for the second foliage cutting device. It is detachably inserted and connected by connection. Further, in the transmission case 8L on the left, another second transmission chain 1730 around which the first sprocket 710 for the foliage cutting device and the second sprocket 1720 for the second foliage cutting device are wound is arranged. ..

According to the configuration shown in FIG. 8, the pair of left and right body cutting rotary blades 510L and 510R are coaxial with the pair of left and right second shoulder alignment drive pulleys 1320L and 1320R by spline connection with the second shoulder alignment drive shafts 1321 and 1321. By making the configuration connected above, the front-rear width of the second shoulder alignment device 1300 can be shortened, the structure can be simplified, the cost can be reduced, and the weight of the aircraft can be reduced.

Further, in the above embodiment, the configuration in which the star foil or the like is not provided between the pair of left and right body cutting rotary blades 510L and 510R and the pair of left and right shoulder alignment belts 310L and 310R has been described, but the present invention is not limited to this. A pair of left and right soft star foils or the like may be provided between them. According to this configuration, it becomes easy to transport the cut radish to the rear without clogging the upper end portion of the main body portion. Further, a pair of left and right soft star wheels may be provided on the rotation shafts of the pair of left and right body cutting rotary blades 510L and 510R.

Further, in the radish extraction machine 1 of the above embodiment, the configuration in which the foliage rotary blade 410 is provided above the shoulder alignment device 300 has been described, but the foliage rotary blade 410 may be set to have a larger diameter. As a result, the foliage rotary blade having a large diameter covers most of the upper surface of the rear portion of the shoulder alignment device 410 in a plan view, so that debris and soil of the foliage portion falling from above can be collected by the shoulder alignment belt of the shoulder alignment device 300. It exerts an effect as a guard body that makes it difficult to enter rotating parts such as 310L and 310R.

Further, in the radish extraction machine 1 of the above embodiment, the foliage rotary blade 410 rotatably provided above the shoulder alignment device 300 is a second foliage cutting device housed in the transmission case 8L on the left side. The configuration described as a configuration in which a spline connection is made to a rotation shaft 721 (see FIG. 7) protruding upward from the sprocket 720, that is, a configuration in which the foliage rotary blade 410 is rotatably supported from below. However, the present invention is not limited to this, and for example, the foliage rotary blade 410 can be provided by providing a bearing portion at the upper end of the rotary shaft of the foliage rotary blade 410 on the left pull-out transport frame 270L of the pull-out transport device 200. It may be configured to be rotatably supported from both the top and bottom.

Further, in the above embodiment, the counter switch 920 (see FIG. 1) counts the number of times the contact member 910 moves backward every time the contact member 910 comes into contact with the radish, thereby detecting the number of radishes. The configuration to be performed was explained. However, the present invention is not limited to this, for example, instead of the foliage rotary blade 410, a non-rotating rectangular straight blade arranged so as to incline and cross the transport path of the shoulder alignment device 300 in a plan view is provided. One end of the straight blade located on the upstream side in the longitudinal direction is rotatably supported within a certain rotation range, for example, 0 ° to 5 °, and the cutting edge of the straight blade is supported by a spring member. It may be configured to be constantly urged toward the upstream side, and a counter switch may be provided so as to be able to contact the back surface of the other end of the side located on the downstream side in the longitudinal direction of the straight blade. As a result, the foliage portion W1 of the radish W conveyed by the pull-out transport device 200 abuts on the cutting edge of the straight blade and opposes the urging force of the spring member, and the straight blade is on the downstream side with one end thereof as the center of rotation. The number of radishes can be counted by rotating the blade within the rotatable range and pressing the counter switch on the back surface of the other end of the straight blade. As an example, the above straight blade has a rectangular shape in consideration of the stability of the posture when it comes into contact with the crop, but in consideration of the cutability of the crop, an arc-shaped blade such as a kitchen knife or a sword Or it may have a saw blade-shaped blade portion so that the blade can easily bite into the crop.
