  In addition, the right-handed pull-out driven pulley 230R and the right-handed holding roller group 240R can be rotated with respect to the right-hand holding force adjustment frame 280R, which is attached to the lower surface of the tip of the right-handed pulling conveyance frame 270R. It is attached to.

  Furthermore, long holes 281 long in the left-right direction are provided in the front and rear two places in each of the left and right pair of holding force adjustment frames 280L and 280R, and the left-right direction (arrows in FIG. H) After sliding and positioning to the H), the left and right pair of holding force adjustment frames 280L and 280R are fixed to the left and right pair of drawn conveyance frames 270L and 270R by fastening members 282 such as bolts and nuts. is there.

  Thus, the operator loosens the fastening member 282 and slides the left and right pair of holding force adjustment frames 280L and 280R in the left and right direction (see the arrow H in FIG. 5) to position the same. By firmly fixing each of the pair of holding force adjustment frames 280L and 280R to the pair of left and right pulling and conveying frames 270L and 270R, the gap G between the pair of left and right pulling and conveying belts 210L and 210R is easy (see FIG. 5) It can be adjusted to

  Therefore, the operator can easily adjust the clamping force on the upstream side of the conveyance path of the pulling and conveying apparatus 200 in accordance with the thickness and working time of the stem and leaf part W1 of the radish W (the presence or absence of morning dew). Is too weak to prevent the radish W from being pulled out of the field, and it is prevented from manually pulling it out, and the holding force is too strong, and the stem and leaf portion W1 is crushed, and the shoulder aligning device 300 removes the stem and leaf portion W1. It can not be taken over, and it can be prevented from being returned to the original hole of the field while the upper end W2b of the main body W2 of the radish W remains, so the upper end W2b of the main body W2 of the radish W is removed in a later step That work does not occur.

  In addition, the operation of adjusting the clamping force on the upstream side of the transport path of the pulling and transporting apparatus 200 can be easily performed by the operation of loosening the fastening member 282 and slidingly moving each of the pair of clamping force adjustment frames 280L and 280R. Work efficiency is improved because it can be done.

  In addition, it changes to the structure which adjusts the clamping force of the drawing-out conveyance apparatus 200 using the fastening member 282 mentioned above, for example, a radish for raw | fed edible, a radish for processing (for example, for oden), pickle with a lever mechanism. The holding force may be switched with one touch in three steps for the radish.

  Next, four pinching rollers constituting the pair of pinching roller groups 240L and 240R on the left and right will be described using FIGS. 6 (a) and 6 (b).

  FIG. 6A is a schematic view for explaining the two-stage roller member 241a among the four pinching rollers constituting the pair of pinching rollers 240L and 240R on the left and right, and the E-E cross section in FIG. FIG. FIG. 6B is a schematic view for explaining the single-stage roller member 241b among the four pinching rollers constituting the pair of pinching rollers 240L and 240R on the left and right, and F-F in FIG. FIG.

  The four pinching rollers constituting the pair of pinching roller groups 240L and 240R mounted on the pair of left and right pinching force adjusting frames 280L and 280R are close to the pair of pullout driven pulleys 230L and 230R as illustrated in FIG. The two-stage roller member A 241a (see FIG. 6 (a)) is one by one, the one-stage roller member 241 b (see FIG. 6 (b)) is one, and then the two-stage roller member 241a. Two (see FIG. 6A) are disposed respectively (see FIG. 1 and FIG. 5).

  As shown in FIG. 6A, in the two-stage roller member 241a, upper and lower two-stage rollers in contact with the inner wall surfaces of the pair of left and right drawn-out transport belts 210L and 210R are rotatably attached to the long axis 241a1. The pressure by the roller is a belt by inserting the rib-like protrusion 211 which protrudes inward from the inner wall surface of the pair of left and right drawn-out conveying belts 210L and 210R into the gap between the upper and lower two stages of rollers. It is a configuration that can be reliably transmitted to the side.

  In the single-stage roller member 241b, as shown in FIG. 6 (b), an upper-stage roller in contact with the inner wall surfaces of the pair of left and right drawn-out transport belts 210L and 210R is rotatably attached to the short shaft 241b1. The upper roller is disposed on the upper side of the rib-like protrusion 211 which protrudes inward from the inner wall surface of the pair of left and right drawn-out conveyance belts 210L and 210R. And a space is secured under the roller.

  In addition, since the single-stage roller member 241 b is disposed corresponding to the position where the stem and leaf portion W1 of the radish W is taken over from the pull-out transfer device 200 to the shoulder alignment device 300, the single-step roller member on the bottom side of the pull-out transfer device 200 The front end portions of the pair of left and right shoulder alignment belts 310L and 310R of the shoulder alignment device 300 can be inserted and disposed in the above-mentioned space 241b (see FIG. 6B). The gap with the device 300 can be shortened, and handover of the stem and leaf portion W1 can be performed reliably.

  As a result, the two-stage roller member 241a is brought into contact with both sides of the rib-like projections 211 of the pair of left and right drawn-out conveying belts 210L and 210R to strengthen the holding force, thereby losing the reaction force when pulling out the radish W Of the radish W can be reliably pulled out of the field.

  Further, in the pair of left and right pulling and conveying belts 210L and 210R, the front end portion of the shoulder aligning device 300 is disposed adjacent to the lower rollerless portion, and the single-stage roller member 241b sandwiches the stem portion W1 via the belt. As a result, the stem and leaf portion W1 is prevented from falling off when taking over to the shoulder alignment device 300.

  In the left pulling and conveying frame 270L, the first tension roller 250L on the left, the second tension roller 251L on the left, and the third tension roller 252L on the left are rotatably supported at their respective end portions, The first pivoting arm 250b and the second pivoting arm are attached with the front end of the first tension spring 250a, the front end of the second tension spring 251a, and the front end of the third tension spring 252a at the other end. The 251b and the third pivoting arm 252b are attached so as to be pivotable about the first pivoting point 250c, the second pivoting point 251c and the third pivoting point 252c.

  As a result, the rear end portions of the first pivoting arm 250b, the second pivoting arm 251b, and the third pivoting arm 252b are fixed to the side surface of the left pulling and conveying frame 270L. Due to the elastic force (contraction force) of the first tension spring 250a, the second tension spring 251a, and the third tension spring 252a, a biasing force that normally rotates clockwise acts in plan view. Due to the biasing force, the left first tension roller 250L, the left second tension roller 251L, and the left third tension roller 252L press the inner peripheral surface of the left drawn conveyance belt 210L with different pressing forces. It is a structure.

  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 weak as going from the upstream side to the downstream side of the transport path. The elastic forces of the first tension spring 250a, the second tension spring 251a, and the third tension spring 252a are adjusted in advance.

  In addition, as for the pullout conveyance frame 270R on the right side, the first rotation arm 250b, the second rotation arm 251b, and the third rotation arm 252b perform the first rotation similarly to the above-described pullout conveyance frame 270L on the left side. It is attached rotatably around the fulcrum 250c, the second pivot fulcrum 251c, and the third pivot fulcrum 252c.

  As a result, the right side first tension roller 250R, the right side second tension roller 251R, and the right side third tension roller 252R sequentially weaken the inner circumferential surface of the right side pulling and conveying belt 210R in the order described in this description.

  Further, the cutting guide bar 420 of the stem and leaf cutting apparatus 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 right shoulder alignment stay 370R. The tip end side of the upper end portion is located above the rotary blade 410 so as not to interfere with the single leaf rotary blade 410 and is disposed at a position overlapping the outer peripheral portion of the rotary blade 410 in plan view (See Figure 7).

  Next, a main body upper end portion discharge guide 800 which has basically the same structure as the upper stem and leaf 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 W2b of the main body W2 cut by the trunk cutting device 500 passes the rear side of the outer peripheral edge of the right shoulder alignment drive pulley 320R, The upper end portion of the main body is discharged so as to discharge rearward from the rear wheel drive shaft 3Ra (see FIG. 2) of the right rear wheel 3R at a position apart from the radish W drawn by the device 200 in plan view. A guide 800 is provided.

  As shown in FIGS. 2 and 7, the upper end discharge guide 800 is curved in a substantially V shape in plan view, and the curved portion is a shoulder on the right side from the exit side of the conveyance path of the shoulder alignment device 300. It is disposed above the right shoulder alignment drive pulley 320R along the rear side of the outer peripheral edge of the alignment drive pulley 320R.

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

  The upper surface of the shoulder alignment drive pulley 320R on the right side and the lower surface of the transmission case 8R on the right side have the same configuration as that of the extraction outlet star foil 293 of the above-described stem and leaf discharge member 290. , And may be detachably attached to the shoulder alignment drive shaft 321 of the right shoulder alignment drive pulley 320R. Thus, the stems and leaves remaining on the upper end W2b of the main body W2 cut by the trunk cutting device 500 are more surely ensured by the uneven portions on the outer peripheral edge of the star wheel for shoulder alignment and the upper end discharge guide 800. And is discharged rearward from the rear wheel drive shaft 3Ra of the right rear wheel 3R.

  As a result, the portion cut by the trunk cutting device 500 and discharged by the upper end discharge guide 800 falls away from the position of the radish which has been returned to the original hole, thus preventing the recovery of the radish. The efficiency of the collection work is improved.

  In addition, the working posture of the machine is disturbed by stepping on the portion where the rear wheels 3L and 3R are discharged, the pulling and conveying device 200 may not pull out the radish, or the cut surface on the upper end side of the main body portion becomes rough, Deterioration is prevented.

  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 W2b of the main body W2 of the radish W is cut by the trunk cutting device 500, and the radish is inclined to contact the back side of the radish returned to the original hole of the field V to incline the radish forward. The apparatus 900 will be described with reference to FIG.

  As shown in FIG. 1, the radish inclination device 900 inclines the radish forward each time it contacts the back side of the radish returned to the original hole, and by the opposing force from the inclined radish. A contact member 910 temporarily moving rearward, and (2) a counter switch 920 for detecting the number of backward movements of the contact member repeated each time the contact member 910 contacts the radish There is.

  The contact member 910 is a rectangular plate-like member which is long in the left-right direction in a front view, and forms a resin member forming an upper end portion of the plate-like member and a lower portion connected to the resin member. It is integrally configured with a rubber member.

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

  The position where the contact member 910 is disposed is generally below the pair of left and right shoulder alignment drive pulleys 320L and 320R in a side view.

  Thus, the portion of the rubber member of the contact member 910 is inclined forward by pushing the radish, and the portion of the resin member connected to the rubber member is moved rearward to By pushing the projection, the number of radishes withdrawn by the withdrawal transport device 200 can be counted and displayed.

  Therefore, the worker can easily grasp the number of radishes collected by reading the value displayed on the counter switch 920, so that the worker does not have to count the collected radishes, and the working efficiency can be improved. The effort is reduced.

  In addition, the radish inclination apparatus 900 of this Embodiment is an example of the crop inclination apparatus of this 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 detection member of the present invention.

  According to the above configuration, when the radish W is pulled out by appropriately performing the left-right direction (see the arrow H in FIG. 5) of the pair of left and right pinching roller groups 240L and 240R of the pulling-out transport device 200, On the other hand, in the range where the largest load is applied, the pressing force by each pinching roller is reliably transmitted to the pair of left and right pulling-out transport belts 210L and 210R, and the stem and leaf portion W1 of the radish W is firmly pinched and moved rearward and upward. As a result, the main body W2 of the radish W is reliably pulled out of the field V.

  Thereafter, as the sheet is conveyed from the pair of left and right first tension rollers 250L and 250R toward the third tension rollers 252L and 252R, the nipping force of the belt by each tension roller of the pulling and conveying apparatus 200 becomes weak.

  On the other hand, the belt interval J1 (see FIG. 7) on the entrance side of the conveyance path in the shoulder aligning device 300 disposed horizontally with respect to the surface of the field V below it is the shoulder W2a of the upper end of the radish W Is configured to be wide enough not to pass upward and is configured not to prevent the upward movement of the radish W by the pulling and conveying apparatus 200, but the belt interval of the conveyance path of the shoulder alignment apparatus 300 is as described above, The width gradually narrows from the upstream side toward the downstream side, and the holding force by the pair of left and right shoulder alignment belts 310L and 310R gradually becomes stronger.

  Thereby, as shown in FIG. 1, the stem and leaf portion W1 of the radish W is moved rearward and obliquely upward along the transport direction A (see FIG. 5) of the pullout transport device 200, but the main body portion W2 The upper shoulder portion W2a of the upper end of the shoulder alignment device 300 is restricted from moving upward by coming into contact with 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 shoulders W2a of the radish W abut against the lower surfaces 310La and 310Ra of the pair of left and right shoulder alignment belts 310L and 310R, the gripping force by the pullout conveying device 200 is weak and the gripping force by the shoulder aligning device 300 is strong Therefore, the upward movement of the shoulder W2a is restricted on the downstream side from the contact position, and the upper end W2b of the main body W2 of the radish W is cut by the trunk cutting device 500 (see FIGS. 1 and 7). The positions in the height direction of the shoulders W2a of the radish W are aligned near the start position.

  Thereby, the positions of the shoulders W2a of the radish W are aligned by the shoulder aligning device 300, so that the upper end W2b of the main body W2 of the radish W of the radish W is reliably cut by the trunk cutting device 500 at a desired position. The stem and leaf portion W1 of the radish W can be cut at a desired position by the stem and leaf portion cutting apparatus 400.

  In addition, since the cutting of the main body W2 is started before the cutting of the stem and leaf W1 of the radish W is started, when the main body W2 is cut, the stem and leaf W1 is aligned with the pulling and conveying device 200 and the shoulder alignment device Since it is firmly held at the upper and lower positions by 300, for example, it is possible to prevent the occurrence of cutting position deviation and cutting failure such as the main body portion W2 being shifted forward and cut diagonally at the time of cutting The surface is finished beautifully.

  In addition, after the upper end W2b of the main body W2 of the radish W is cut, the main body W2 of the radish W falls and returns to the original hole (see FIG. 1).

  Therefore, there is no need to perform the cutting operation of the upper end portion W2b of the main body portion W2 of the radish W in the post-processing, and the improvement of the working efficiency and the reduction of labor can be achieved.

  In addition, since the radish returned to the hole in the field can be inclined forward by the radish inclination apparatus 900, and the hole in the place where the radish was vegetated becomes large, it is easy for the operator to lift it when recovering the radish. Work efficiency is improved.

  In addition, the provision of the counter switch 920 eliminates the need for the operator to count the number of collected radishes.

  Further, since the stem and leaf portion W1 cut by the stem and leaf portion cutting device 400 does not have the upper end portion W2b of the radish W, the upper stem and leaf discharge guide 291 and the lower stem and leaf discharge from the outlet of the transport path of the pulling and transporting device 200 It is guided by the guide 292, and is discharged smoothly to the right of the vehicle without being caught.

  In addition, by making the foliage discharging member 290 removable and making it possible to change the discharging direction of the cut foliage, the foliage cut according to the cultivation position of the radish and the necessity of recovery of the cut foliage. Since the discharge position of the part can be changed, the stem part which has been discharged and dropped is covered on the radish to prevent it from interfering with the recovery work of the radish, and the working efficiency is improved.

  In the upper end portion W2b of the radish W cut by the trunk cutting device 500, the stem and leaf portion left there is a shoulder on the right side from the outlet side of the conveyance path of the shoulder aligning device 300 by the upper end discharge guide 800. By being conveyed along the rear side of the outer peripheral edge of the alignment drive pulley 320R, it is discharged rearward from the rear wheel drive shaft 3Ra of the right rear wheel 3R.

  In addition, the shoulder alignment drive shafts 321 and 321 of the pair of left and right shoulder alignment drive pulleys 320L and 320R are based on the transport direction of the shoulder alignment device 300 (see arrow A ′ in FIG. 7). By being disposed on the downstream side of the bosses 511, 511 of the respective 510L, 510R, the load generated when the pair of left and right trunk cutting rotary blades 510L, 510 cut the radish is the pair of left and right shoulder alignment drive pulley 320L Since the shoulder alignment drive shafts 321 and 321 of 320R can be prevented from being directly received, 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, It is prevented that the cutting position of the stem and leaf part is disturbed and that the radish is not pulled out sufficiently.

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

  The left and right shoulder alignment belts 310L and 310R of the present embodiment correspond to an example of the left and right endless endless alignment 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 portion cutting blade of the present invention.

While demonstrating 600 L and 600 R, the 2nd chain transmission mechanism 700 which transmits the driving force from the engine 4 to the single foliage rotary blade 410 is demonstrated.

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

  As shown in FIG. 7, in the pair of left and right first chain transmission mechanisms 600L and 600R, (1) power branched in the left and right direction from the front end of the transmission shaft 6b (see FIG. 7) It is disposed in front of the pair of left and right first sprockets 610L, 610R transmitted through the vertical transmission shafts 6e, 6e vertically disposed at both ends, and (2) the pair of left and right first sprockets 610L, 610R, downward. A pair of left and right second sprockets 620L and 620R, each having a long extending pivot shaft 621 and 621 and to which the left and right pair of left and right rotary blades 510L and 510R are detachably splined connected , (3) a pair of left and right first transmission teeth formed by winding the pair of left and right first sprockets 610L and 610R and the pair of left and right second sprockets 620L and 620R Over emissions 630L, it is provided with a 630R, the.

  Further, as shown in FIG. 7, in the second chain transmission mechanism 700, (1) the power branched leftward from the front end of the transmission shaft 6b (see FIG. 7) is perpendicular to the right end of the transmission branch case 6d. A first sprocket 710 for a stem and leaf cutting device coaxially disposed on the first sprocket 610L coaxially with the left first sprocket 610L, which is transmitted via the vertical transmission shaft 6e disposed in The second for the stem and leaf portion cutting device disposed below the single stem and leaf rotary blade 410 and having a pivot axis extending upward, to which the stem and leaf rotary blade 410 is detachably splined connected to the pivot axis A sprocket 720, and (3) a second transmission chain 730 in which a first sprocket 710 for stem and leaf cutting device and a second sprocket 720 for stem and leaf cutting device are wound.

  Further, with the above configuration, a space is secured below the trunk cutting device 500, so the upper end W2b is cut and contacts the radish W returned to the original hole of the field V, and the main body W2 is damaged. It is possible to prevent the decline in the commercial value.

  Further, the rubber member portion of the contact member 910 pressing the main body W2 of the radish has elasticity, so that the main body W2 of the radish is not damaged, and the reduction of the commercial value is prevented. .

  Also, by arranging the pair of left and right shoulder alignment belts 310L and 310R to be substantially horizontal posture with respect to the eyebrow scene, when aligning the position of the shoulder W2a at the upper end of the main body W2 of the radish W, The shoulder W2a at the upper end of the main body 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 further pulling upwards. The belt is prevented from coming off and coming off.

  Further, by providing the pair of holding rollers 240L and 240R on the drawing and conveying apparatus 200, the holding force in the vicinity of the entrance of the conveyance path of the drawing and conveying apparatus 200 becomes strong. Because it is possible to hold it, it can be pulled out from the field surely, and the efficiency of the recovery work of radish is improved.

  Further, as shown in FIG. 3, each of the pair of left and right pulling out and conveying apparatus covers 202L and 202R described above is configured to be divided into front and rear portions in the vicinity of the center in plan view.

  That is, the left pulling and conveying apparatus cover 202L is composed of the left front cover 202La and the left rear cover 202Lb, and the right pulling and conveying apparatus cover 202R is composed of the right front cover 202Ra and the right rear cover 202Rb It is done.

  Thus, for example, in the case of adjusting the pullout drive pulley 220R on the right side, necessary work can be performed by removing only the portion of the right rear cover 202Rb in the pullout transfer device cover 202R on the right side. In the case of adjusting the pullout driven pulley 230L side, necessary work can be performed by removing only the portion of the left front cover 202La in the pullout conveyance device cover 202L on the left side, so that the work efficiency is improved.

  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 and 510R, and a second stem and leaf rotary blade 1410 as another structural example different from the structural example shown in FIG. . The same components as those shown in FIG. 7 are denoted by the same reference numerals and the description thereof will be omitted. In the configuration example shown in FIG. 8, the blade edge on the upstream side of the portion of the conveyance path formed by the pair of left and right second shoulder alignment belts 1310 L and 1310 R in plan view of the pair of left and right barrel cutting rotary blades 510 L and 510 R The portion is configured to be located downstream of the portion of the blade edge upstream of the portion existing on the transport path in plan view of the single second stalk rotary blade 1410. Moreover, in order to guide the stem and leaf portion W1 to the second stem and leaf rotary blade 1410 side in order to prevent the stem and leaf portion W1 from being pushed by the second stem and leaf rotary blade 1410 and escaped, a substantially reverse L-shaped first side 2 A cutting guide bar 1420 is provided. In addition, a pair of left and right barrel cutting rotary blades 510L and 510R are spline-connected via bosses to second shoulder-aligned drive shafts 1321 and 1321 extending downward from the pair of left and right second shoulder-aligned drive pulleys 1320L and 1320R.

Further, in the case of the configuration of FIG. 8, the pivot shafts 621 and 621 extended downward from the pair of left and right second sprockets 620L and 620R accommodated in the left and right transmission cases 8L and 8R have a pair of left and right second shoulders. The alignment drive pulleys 1320L and 1320R are detachably connected by spline connection. Further, in the case of the configuration of FIG. 8, the second stem portion cutting device second sprocket 1720 housed in the left transmission case 8L is disposed in front of the left second sprocket 620L in plan view. In addition, the single second stalk rotary blade 1410 disposed above the left transmission case 8L is splined with respect to the second rotation shaft 1721 that protrudes upward from the second sprocket 1720 for the second foliage cutting device. It is detachably connected by connection. In the left transmission case 8L, another second transmission chain 1730 in which a first sprocket 710 for a stem and leaf cutting device and a second sprocket 1720 for a second stem and leaf cutting device are wound is disposed. .

  According to the configuration shown in FIG. 8, the left and right pair of barrel cutting rotary blades 510L, 510R are coaxially connected by spline connection to the second shoulder aligned drive shafts 1321, 1321 of the left and right pair of second shoulder aligned drive pulleys 1320L, 1320R. By employing the above-connected configuration, the front-rear width of the second shoulder alignment device 1300 can be shortened, the structure can be simplified, and cost reduction and weight reduction of the airframe can be achieved.

  In the above embodiment, a configuration in which the star wheel or the like is not provided between the pair of left and right trunk cutting rotary blades 510L and 510R and the pair of left and right shoulder alignment belts 310L and 310R has been described. A configuration in which a pair of left and right soft star wheels or the like are provided between these may be used. According to this configuration, the upper end portion of the main body portion of the cut radish can be easily transported backward without being clogged. In addition, a pair of left and right soft star wheels may be provided on the rotation axis of the pair of left and right barrel cutting rotary blades 510L, 510R.

  Further, in the radish extraction machine 1 of the above embodiment, the foliage rotary blade 410 is provided above the shoulder alignment device 300. However, the diameter of the foliage rotary blade 410 may be set larger. As a result, the large diameter foliage rotary blade covers most of the upper surface of the rear of the shoulder alignment device 410 in plan view, so debris and soil of the stem and leaf portions falling from the top can be aligned with the shoulder alignment belt of the shoulder alignment device 300 It exerts an effect as a guard body which makes it difficult to enter into the rotating parts such as 310L and 310R.

  Further, in the radish extraction machine 1 of the above-described embodiment, the foliage rotary blade 410 provided rotatably above the shoulder alignment device 300 is the second for the foliage cutting device housed in the transmission case 8L on the left side. The structure which is spline-connected with respect to the rotational shaft 721 (see FIG. 7) protruding upward from the sprocket 720, that is, the foliage rotary blade 410 has been described as the structure supported rotatably from below. However, the present invention is not limited to this. For example, by providing the bearing portion of the upper end portion of the pivot shaft of the above-mentioned foliage rotary blade 410 on the pullout conveyance frame 270L on the left side of the pultrusion conveying device 200 It may be configured to be rotatably supported from both the upper and lower sides.

  In the above embodiment, the counter switch 920 (see FIG. 1) counts the number of backward movements of the contact member 910 repeated each time the contact member 910 contacts the radish, thereby detecting the number of radishes. Configuration has been described. However, the present invention is not limited to this, and for example, instead of the stem and leaf portion rotary blade 410, it has a non-rotating rectangular straight blade arranged to traverse the transport path of the shoulder aligning device 300 in an inclined manner in plan view One end on the upstream side of the straight blade in the longitudinal direction is rotatably supported within a fixed rotation range (for example, 0 ° to 5 °), and the cutting edge of the straight blade is a spring. It is a configuration that is always urged toward the upstream side by a member, and a counter switch is provided so as to be in contact with the back surface of the other end of the straight blade located on the downstream side in the longitudinal direction. good. Thereby, the stem and leaf portion W1 of the radish W conveyed by the drawing and conveying apparatus 200 abuts against the blade edge of the straight blade and opposes the biasing force by the spring member, and the downstream side of the straight blade with its one end as a rotation center When the back surface of the other end of the straight blade pushes the counter switch, the number of radishes can be counted. In addition, although the above-mentioned straight blade is made into a rectangular shape in consideration of stability of a posture when contacting with a crop as an example, an arc-shaped blade portion such as a kitchen knife or a sword etc. in consideration of the cutting property of the crop In order to make it easier for the blade to bite into the crop, it may be provided with a saw blade.

  Further, in the radish extraction machine 1 of the above-described embodiment, by providing brushes or scrapers (not shown) on the outer surfaces of the transmission cases 8L and 8R arranged on the left and right, a pair of left and right shoulder alignment belts 310L and 310R are provided. The outer peripheral surface of the may be cleaned.

  Further, in the radish extraction machine 1 according to the above-described embodiment, the raising mechanism 100 may be configured to float by providing a ground ring (not shown). Further, in this case, the ground contact wheel may be disposed behind the pair of left and right lateral pulling devices 130L and 130R and below the front end of the pulling and conveying device 200. Also, in this case, the ground wheel may be configured to be adjustable in its mounting height.

  The diameter of the ground contact wheel provided in the raising mechanism 100 is smaller than at least the gauge wheel 2 (see FIG. 1). Specifically, it is desirable that the front-rear distance between the lower end rear portion of the raising mechanism 100 and the front-rear distance immediately below the conveyance start end of the pulling and conveying apparatus 200 have substantially the same diameter. Further, the lateral width of the contact wheel is the same as that of the gauge wheel 2 or is wider than that of the gauge wheel 2.

  As a result, even if the ground contact wheel is provided, the front and rear width of the raising mechanism 100 can be prevented from becoming significantly wide, and the making of the raising mechanism 100 can be made compact. Further, by making the lateral width of the ground contact wheel the same as or wider than the gauge wheel 2, the contact pressure of the ground contact wheel is reduced, and it is possible to prevent the travelability from being impeded.

  Further, in the above embodiment, the pair of left and right substantially inverted U-shaped pipe members is covered with respect to the back side of the rear covers 133 b and 133 b to cover each of the left and right pair of lateral pulling devices 130 L and 130 R from the rear side. A description has been given of the case where the front ends of the pair of left and right parallel link arms 160L and 160R whose rear ends are rotatably connected to the side surfaces of the front ends of the 203L and 203R are connected and fixed by fastening members ( 1 and 3). However, the present invention is not limited to this, for example, an actuator that adjusts the upper and lower positions of the raising mechanism 100 by connecting the rear end portions of the parallel link arms 160L and 160R to the rotation shaft and raising and lowering the raising mechanism 100. (Not shown) may be disposed at the upper end of the left (or right) substantially inverted U-shaped pipe member 203L (or 203R).

  In this case, the front end of the substantially cylindrical actuator configured to be movable in the front-rear direction by the rotation of the rotation handle is provided upright on the upper surface of the left (or right) parallel link arm 160L (or 160R).
