When the handle 29 is turned, a rotatable gauge ring 31 is provided at the lower end portion of the telescopic rod 30 that vertically expands and contracts to prevent the pulling and conveying device 24 from descending too much.

  Further, left and right solitary frames 32, 32 are attached from substantially lower positions in the longitudinal direction of the fuselage from the lower front side of the fuselage frames 15, 15, and left and right vibrations are attached to the front ends of the sora frames 32, 32. The front end portions of the arms 33 and 33 are attached. A vibration shaft 34 that rotates in response to the driving force of the engine 7 is extended toward the pulling / conveying device 24 on the front side of the body frame 1, and the vibration shaft 34 and the rear end portions of the vibration arms 33 and 33 are arranged. A vibrating rod 35 having a V-shape in a side view for vibrating the vibrating arms 33 and 33 is attached to constitute a vibrating device 36. The vibration arm 33 inside the machine body is rotatably attached to the lower end side of the vibration rod 35.

  Then, left and right soilers 37, 37 that cut through the soil around the carrots are attached to the connecting portion between the solitary frames 32, 32 and the vibrating arms 33, 33 toward the front side of the machine body. The bases of the left and right soil drop stays 38, 38 are attached to the inside of the place where the bases 37, 37 are attached, and the vibration device 36 is configured.

  In addition, if the said soira 37 is comprised from the blade part 37a which penetrates into the soil and unwinds the soil around the carrot, and the arc-shaped attachment part 37b which goes back and upwards from this blade part 37a, the soira 37 will be the soil. Since the resistance applied when entering the inside is dispersed and reduced, the aircraft progresses smoothly and the work efficiency improves, and it is matched to the difference in field conditions due to soil quality and weather, and the type and growth state of carrots. Since the vertical position of the soiler 37 can be easily adjusted, it is easy to dig up carrots and work efficiency is improved.

  Further, since the rotation speed of the vibration shaft 34 that vibrates the vibration device 36 is not linked to the speed change operation of the transmission case 8, the vibration width does not change even when the traveling speed is low. Since the left and right soilers 37 can be vibrated with the same width even during the work, the work efficiency is improved, and the soil around the carrots is cut out, so there is less leftover, so it is left behind after the harvesting work. The work of removing the carrots is omitted, and the labor of the worker is reduced.

  In addition, earth removal brushes 39 and 39, which are earth removal members made of synthetic resin such as polypropylene and acrylic, or natural materials such as cocoons and wool, are used to drop the dirt adhering to carrots on the rear portions of the earth removal stays 38 and 38. Install. In addition, if the hair of the same length is used for the top and bottom of the soil removal brushes 39 and 39, the upper and lower surfaces of the soil removal brushes 39 and 39 are changed when the upper hair, which has many opportunities to come into contact with carrots, is worn. If this is the case, the hair that has not been worn can be brought into contact with the carrot, so that the soil removal brushes 39 and 39 can be made to last longer.

  Further, the left and right distances between the dirt removing brushes 39 and 39 are arranged such that the front side of the aircraft is widest and the width W1 is narrower toward the rear side of the aircraft, and the narrowest partial width of the earth removing brushes 39 and 39 is narrowest. W2 is configured to face left and right.

  And the front end part of the left and right soilers 37, 37 crawls up and down the left and right lifting projections 40, 40 that crawl up the foliage hanging in the field, and the front part is located in front of the lateral lugs 26 a of the device 26. Arrange to do. Further, the left and right guide bars 41, 41 that guide the stems and leaves scooped up by the ridge protrusions 40, 40 to the front side of the ridge protrusions 40, 40 to the holding start end of the pulling and conveying device 24 are shown in a plan view. The guide bars 41 are attached so that the left and right spacing between the guide bars 41 decreases toward the rear side of the machine body.

  When the guide bars 41 and 41 are made of a cylindrical elastic material having a high degree of flexibility such as a piano wire and having a certain degree of hardness, the vibration width is increased and the effect of preventing the tangles from being entangled is improved.

  Further, left and right weed bodies 42, 42 that are wider than the above-mentioned ridge protrusions 40, 40 and cover the upper surfaces of the ridge protrusions 40, 40 in a tilted rearward posture are provided. In addition, the space part in which the said guide bars 41 and 41 protrude is formed in the upper part of the weed bodies 42 and 42. As shown in FIG.

  Here, another example of the soiler 37 and the soil removal brush 39 according to the present invention will be described. The earth removing brush 39 in this example does not use a plurality of upper and lower bristles as in the above example, but uses an elastic bar 120 and a plurality of rollers 121 on the bar 120. It is a thing. Hereinafter, the description of this example will mainly describe a configuration different from the above example, and a description of the same configuration as the above example will be omitted.

  The left and right soiler frames 32 extend horizontally in the front-rear direction, and the cross-section thereof is an L-shape including upper and lower plate portions 32a extending in the vertical direction and left and right plate portions 32b extending from the upper ends of the upper and lower plate portions 32a in the left-right direction. It has become. The vibration arm 33 swings around the rotation fulcrum shaft 122 provided at the front end portion of the soiler frame 32. The soiler 37 rotates with the connecting fulcrum of the vibration rod 35 in the vibration arm 33 by the mounting portion 37b. A plurality of (two) mounting bolts 123 are attached to the front portion between the fulcrum shafts 122. The mounting portion 37 b is provided with a plurality (two) of mounting holes 124 through which the plurality (two) of mounting bolts 123 are inserted at different positions, and the mounting bolts 123 are inserted therethrough. By selecting the mounting hole 124, the height of the soiler 37 can be adjusted in a plurality of stages (three stages). Moreover, since the attachment part 37b is a structure attached to the vibration arm 33 with the two attachment bolts 123 arrange | positioned forward and backward, the soiler 37 can be attached to the vibration arm 33 by the attachment part 37b facing up and down.

  The rotation fulcrum shaft 122 of the vibration arm 33 supports a bearing 125 disposed in a space in the L-shape of the soiler frame 32, and the vibration arm 33 is attached via the bearing 125. The rotation fulcrum shaft 122 is fastened and fixed to the upper and lower plate portions 32 a of the soiler frame 32 by a nut 126 disposed in the L shape of the soiler frame 32, similarly to the bearing 125. The head portion 122a of the pivot fulcrum shaft 122 opposite to the left and right sides of the nut 126 is configured to be extremely thin, and damages to the root vegetables conveyed by the pulling and conveying device 24 while suppressing the protrusion of the soiler frame 32 on the inner side in the left and right direction. Is not attached.

  The front end edge of the blade portion 37a has a saw-tooth shape, and is formed in a mountain shape extending linearly upward and downward with the upper and lower central portions as apexes in a side view of the machine body. The upper part and the lower part of the apex are the one end part 127 and the other end part 128 in the vertical direction of the blade part 37a. The blade portion 37a is vertically symmetric with respect to the center line 129 in the front-rear direction passing through the apex in a side view of the machine body. Accordingly, the front end edges of the one end portion 127 and the other end portion 128 are connected so as to be bent at the vertex that is the central portion in the vertical direction, and are not on the same straight line. Of the plurality of sets (three sets) of mounting holes 124, the plurality (two) of mounting holes 124 serving as intermediate positions in height adjustment are located on the center line 129. The plurality of (two) mounting holes 124 in the remaining group are positioned on a straight line parallel to the center line 129 in each group. In addition, when the blade 37a is switched to the mounted state, regardless of which one of the one end 127 and the other end 128 is above the soiler 37, the entire range of the vertical swing of the soiler 37 due to the swing of the vibration arm 33 is further extended. Thus, the front end edge of the upper part of the soiler 37 rises rearward, and the front end edge is located on the rear side as it goes upward. And the upper part of the soira 37 acts as a weeding part which breaks the entanglement with the stem and leaf part of the root vegetable of the adjacent cultivation strip while swinging up and down to weed the stem and leaf part of the root vegetable.

  In addition, since the front end edge of the soira 37 is uneven | corrugated like the saw blade shape, the weeding effect can be heightened. And in the situation where the entanglement of the foliage part is intense and the weeding of the foliage part is difficult, it is configured to cut the foliage part with a saw blade-like front edge, and the root vegetables of the adjacent cultivation strip are involved. Can be prevented. In addition, there is a relief at the saw blade-shaped front end edge so that chips of the foliage are not left on the front end edge. In addition, the saw blade-like front end edge can sufficiently obtain the action of tearing the soil, increasing the soil unraveling effect.

  Further, the front end edge of the one end portion 127 in the vertical direction of the blade portion 37a is a linear shape extending linearly in the vertical direction at the same left and right position, but the front end edge of the other end portion 128 in the vertical direction of the blade portion 37a is It has a curved shape with a curved portion 128b that bends in the left-right direction following a straight portion 128a that linearly extends in the vertical direction at the same left-right position from the apex. In the state where the soiler 37 is mounted so that the other end portion 128 is on the lower side, the bent portion 128b is positioned on the cultivation strip side of the root vegetables in the field as it goes downward, and the bent portion is below the root vegetables on the field. The tip of 128b is located. Accordingly, when the soiler 37 is mounted so that the other end portion 128 is at the upper portion, the bent portion 128b is bent to the side away from the root vegetables (outside in the left-right direction) as it goes upward.

  Each of the left and right earth removing brushes 39 has a configuration in which an elastic bar 120 is attached by two bar mounting bolts 130 in the vicinity of a connection fulcrum with the vibration rod 35 of each vibration arm 33. The two rod mounting bolts 130 are arranged on the front lower side and the rear upper side. An annular portion 120a bent in a U shape is formed at the end of the rod member 120, and a rod mounting bolt 130 is inserted into the annular portion 120a. The bar 120 includes an upper extending portion 120b that extends upward from the annular portion 120a, a soil dropping operation portion 120c that is bent at the upper end of the upper extending portion 120b and extends linearly obliquely to the rear lower side, and a soil removing operation portion. Following the rear end of 120c, it is provided with a retracting portion 120d extending linearly at the lower rear side. In addition, the soil dropping operation part 120c is located on the cultivation strip side (inner side) of the root vegetables to be harvested as it goes rearward in the plane view of the machine body. Therefore, the distance between the left and right soil dropping action parts 120c is closer to the rear side. It is narrower. In addition, the retracting portion 120d is positioned on the opposite side (outside) of the root crops to be harvested as it moves rearward in plan view of the machine body. Therefore, the distance between the left and right retracting portions 120d becomes wider toward the rear. ing.

  A plurality (large number) of rollers 121 are provided to rotate freely in the soil dropping operation part 120c and the retreating part 120d. The roller 121 is made of a hard resin and has excellent wear resistance. Although the roller 121 reduces the contact resistance with root vegetables, the rear end of the retracting portion 120 d, that is, the rearmost roller 121 a located at the rearmost position is fixed to the bar 120 by the fixing bolt 131. Therefore, the roller 121 before the last roller 121a is regulated so as not to come off the bar 120 by the last roller 121a. In addition, the front end of the soil removal action part 120c, that is, the roller 121 located at the forefront may also be fixed to the bar 120. In addition, since a large number of rollers 121 rotate individually, each roller 121 that comes in contact with the root vegetables is free even when the root vegetable roots in the field are narrow and a plurality of root vegetables are supplied to the soil removal operation unit 120c at the same time. It can rotate to reduce contact resistance. Furthermore, the end of each roller 121 is chamfered so that the root vegetables that come into contact with the roller 121 are not damaged. Further, when replacing the plurality of rollers 121, the fixing bolt 131 is loosened and the last roller 121 a is removed to remove the roller 121 before the last roller 121 a from the bar 120.

  The bar 120 is made of an elastic metal, but has a shape that does not resonate even when vibration of the vibration arm 33 is transmitted and has sufficient strength. Further, the bar 120 is attached by a bar mounting bolt 130 from the vibration arm 33 via each mounting spring 132 that is a hard compression spring, and the amount of tightening of the bar mounting bolt 130 is changed. Thus, the left and right positions can be changed. That is, if the amount of tightening of the two rod mounting bolts 130 is small, the rod 120 is positioned on the cultivation strip side (inside), and if the amount of tightening of the two rod mounting bolts 130 is large, the rod 120 becomes a structure located in the other side (outside) of a cultivation strip. Further, if the amount of tightening of the front lower bar mounting bolt 130 is increased and the amount of tightening of the rear upper bar mounting bolt 130 is decreased, the bar 120 is positioned on the cultivation strip side (inner side), If the amount of tightening of the front lower bar mounting bolt 130 is reduced and the amount of tightening of the rear upper bar mounting bolt 130 is increased, the bar 120 is positioned on the opposite side (outside) of the cultivation strip. Thereby, the space | interval of the right and left earth dropping brush 39 can be changed.

  In the above example, the soy 37 having the above-described configuration is provided on each of the left and right sides. However, the soy 37 having the above-described configuration is provided on the already harvested side where the root vegetables are not already present with respect to the cultivation strip of the root vegetable to be harvested. Alternatively, another soiler 37 having a smaller vertical width than the soiler 37 having the above-described configuration, such as the above-described example or another example 3 described later, may be provided.

Thus, the remaining leaf transport device 114 that sandwiches the upper part of the foliage and transports it to the rear of the machine body is configured above the defoliation transport device 109.

The defoliation transport device 109 and the remaining leaf transport device 114 constitute a pair of foliage sandwiching transport devices 45i and 45o on the outside of the body.
Then, the carrot foliage being transferred to the drive shaft 28 projecting downward from the first gear unit 96 outside the machine body constituting the foliage conveying apparatus 45o outside the machine body and behind the shoulder aligning device 44o outside the machine body is cut. The disk-shaped first rotary blade 46o is attached to the drive shaft 28 that protrudes downward from the first gear unit 96 inside the machine body behind the shoulder aligning device 44i inside the machine body and inside the machine body constituting the foliage conveying device 45i inside the machine body. A disk-shaped second rotary blade 46i for cutting the carrot foliage being transported is attached to be rotationally driven, and the second rotary blade 46i is disposed below the first rotary blade 46o to provide a foliage cutting device 47. Configure. The first cutting blade 46o and the second cutting blade 46i are arranged so that the outer peripheral edges overlap, and are rotated so as to sandwich the root vegetables on the front side, and the first rotating blade 46o and the second rotating blade 46i are on the outer periphery. An arc-shaped circular blade with a smooth cutting edge and a saw-round blade with an uneven outer peripheral cutting edge are combined.

  Further, a spacer 48 thicker than the plate thickness of the first cutting blade 46o and the second cutting blade 46i is mounted below the second cutting blade 46i and below the drive shaft 28 of the first cutting blade 46o. The ginseng edible portion before cutting is elastically deformed by being contacted from the side, and the ginseng after cutting is orthogonal to the conveying direction of the foliage sandwiching and conveying devices 45i and 45o by elastic restoring force. A push-out disk 49 is attached to the remaining leaf processing conveyor 57, which will be described later, and dropped in a state where the shoulder portion of the carrot is directed to the inner side of the body where the remaining leaf processing roller 56 is disposed. The extrusion disk 49 is formed of an elastic body that is easily deformed and has strong elastic force, such as rubber, and is configured to rotate together with the first cutting blade 46o. The spacer 48 has an outer diameter that does not contact the largest diameter carrot.

Note that the spacer 48 may be a disk blade.
Further, if the extruded disk 49 has substantially the same diameter as the first cutting blade 46o or a slightly larger diameter than the first cutting blade 46o, the extruded disk 49 can easily come into contact with the ginseng shoulder, and the ginseng shoulder becomes the fuselage. It is possible to make the posture facing inward, and the remaining leaf processing conveyor 57 reliably processes the leaf and leaf portion remaining on the root portion, so that it is not necessary to remove this leaf and leaf portion in a subsequent process, and the work efficiency is improved.

  Further, as shown in FIG. 23, the extrusion disk 49 is eccentrically attached inside the outer circumference of the first rotary blade 46o, and is prevented from rotating in synchronization with the ginseng planting interval. To be distributed.

Further, as shown in FIG. 24, the outer periphery of the extrusion disk 49 is partially made uneven so that large and small carrots can be easily skipped.
Furthermore, the extrusion disk 49 may be formed in a dish shape with the outer peripheral edge facing downward, or may be softened by providing a slit on the outer peripheral edge.

The extrusion disk 49 can be removed as appropriate.
Since the average thickness of the first cutting blade 46o and the second cutting blade 46i is about 1 mm, the thickness of the spacer 48 is about 2 mm, so that the first cutting blade 46o and the second cutting blade 46i are formed on the extrusion disk 49. It becomes difficult to entrain.

  As shown in FIG. 18, the first rotary blade 46o and the second rotary blade 46i are attached to the drive shaft 28. As shown in FIG. 18, the first rotary blade 46o (second rotary blade 46i) is driven and rotated. An attachment member 81 for attaching and fixing the blade 46o and the second rotary blade 46i, and an adjustment knob 82 for adjusting the height position of the attachment member 81 are provided. The attachment member 81 rotates integrally with the drive shaft 28 and has a shaft core. The adjustment knob 82 is engaged with the drive shaft 28 via screw portions 82c and 28b, is rotatable with respect to the attachment member 81, and slides in the axial direction integrally with the attachment member 81. It is configured as possible. The outer periphery of the adjustment knob 82 is hexagonal so that it can be easily turned. The hexagonal corner may be cut slightly.

  A nipple 92 is attached to the lower end of the drive shaft 28 via a washer 91, and grease is supplied to the prism portion 28a through an oiling hole provided in the center of the drive shaft 28. The washer 91 prevents the adjustment knob 82 from coming off.

  Therefore, the attachment member 81 moves up and down by an easy operation of simply rotating the adjustment knob 82, and the cutting height of the first rotary blade 46o and the second rotary blade 46i, that is, the root vegetable stem and leaf portion sandwiching and conveying device 45i. , 45o can be adjusted, and the body of the foliage can be cut or the edible part near the shoulder can be cut or changed.

  Further, since the rotation regulating means (spring 82a and ball 82b) for regulating the rotation of the adjustment knob 82 with respect to the drive shaft 28 is provided, the adjustment knob 82 rotates with respect to the drive shaft 28 during the drive rotation of the drive shaft 28. Thus, the cutting height of the first rotary blade 46o and the second rotary blade 46i is prevented from changing, and the cutting process can be performed accurately. The position where the rotation restricting means (spring 82a and ball 82b) is provided is provided toward the apex having the maximum hexagonal diameter.

  The rotation restricting means can be configured to integrally fix the adjustment knob 82 with respect to the drive shaft 28 in the rotation direction, and when the adjustment knob 82 attempts to rotate more than a certain angle with respect to the drive shaft 28, It can also be configured to increase the resistance to rotation.

  In the illustrated example, by taking the latter configuration, when adjusting the cutting height of the first rotary blade 46o and the second rotary blade 46i, it is not necessary to release the rotation restricting means, and resistance to the rotation restricting means is reduced. Accordingly, the adjustment can be performed simply by rotating the adjustment knob 82 with respect to the drive shaft 28, and the adjustment operation can be performed very easily. Further, when the fixing of the first rotary blade 46o (second rotary blade 46i) to the mounting member 81 is released (screwing is removed in the illustrated example), the first rotary blade 46o and the second rotary blade 46i are moved to the rotation center side. The size of the hole and the size of the adjustment knob 82 are set so that the formed hole can pass through the adjustment knob 82. Accordingly, the first rotary blade 46o (second rotary blade 46i) can be removed without removing the adjustment knob 82, and the rotary blade can be easily replaced.

  FIG. 19 shows another example of the vertical movement fixing means for the first rotary blade 46o and the second rotary blade 46i. An attachment member 81 is inserted into a rotation preventing prismatic portion 28a formed at the lower portion of the drive shaft 28 so as to be movable only in the axial direction, and the first rotary blade 46o (second rotary blade 46i) is fixed to the attachment member 81. At the same time, the adjustment knob 82 for positioning the attachment member 81 up and down is attached to the screw portion 28b at the lower end of the drive shaft 28 by screwing a screw hole 82c formed in the lower portion of the adjustment knob 82. The adjustment knob 82 is provided with a rotation restricting means by a ball 82b that is elastically pressed by a spring 82a that can roll on the outer periphery of the prism portion 28a. Between the support part 27c holding the first rotary blade 46o (second rotary blade 46i) and the attachment member 81, an engagement sphere 83 is interposed so that the support part 27c and the attachment member 81 rotate integrally. The movement of the first rotary blade 46o (second rotary blade 46i) side in the direction of the rotational axis is restricted by the retaining ring 83a, and the groove formed on the lower outer periphery of the mounting member 81 and the upper portion of the adjustment knob 82 Engagement spheres 84 are interposed in holes formed at a plurality of positions in the rotation direction on the side, and a retaining ring 84a is attached so that the engagement spheres 84 do not fly out. As a result, the adjustment knob 82 is rotatable with respect to the mounting member 81 and can slide in the axial direction integrally with the mounting member 81.

A fixing sleeve 85 and a large-diameter portion 86 at the lower end thereof are fixed to the lower portion of the drive shaft 28 via a non-rotating rectangular column portion 28a. In the fixed sleeve 85, the outer peripheral surface is equally divided to form an engaging groove 85a ... by an axial groove, and the first rotary blade 46o (second rotary blade 46i) is supported by a screw portion 85b formed below the fixed groove 85. The cylindrical part 87 connected to the part 27d is screwed together. A through hole 87b is formed in the cylindrical portion 87, and the engaging sphere 87a that can be interposed between the locking grooves 85a of the fixing sleeve 85 is provided to be able to advance and retreat from the through hole 87b. Is provided with a slide sleeve 88 for controlling the advancement and retraction of the engaging sphere 87a.

  The slide sleeve 88 is configured to be slidable in the axial direction by an engaging sphere 88 a interposed in an axial groove 87 c formed on the outer periphery of the cylindrical portion 87. The slide sleeve 88 has a lower stroke position range from the upper limit position reaching the support portion 27d at the upper end of the cylindrical portion 87 to the large diameter portion 86, and a coil spring 89 is provided to bias the slide sleeve 88 to the lower limit position. Further, a taper 88b for controlling the advancement and retraction of the engagement sphere 87a of the cylinder portion 87 is formed. This taper 88b restrains the engagement sphere 87a in the inner locking groove 85a... At the lower limit position of the slide stroke. On the other hand, the inclined surface is formed so as to restrict the rotation of the portion 87 and release the restraint of the engaging sphere 87a at the upper limit position of the slide stroke to permit the rotation of the support portion 27d.

  With the above configuration, the first rotary blade 46o and the second rotary blade 46i are moved up and down to narrow or widen the distance between the foliage sandwiching and conveying devices 45i and 45o (specifically, the shoulder aligning devices 44i and 44o). The foliage part is cut and the edible part is cut.

  A bellows 90 that covers the drive shaft 28 is provided between the first gear unit 96 and the first rotary blade 46o and between the first gear unit 96 and the fixed sleeve 85 of the second rotary blade 46i so that the leaf does not wind. I have to.

  As described above, this root vegetable harvesting machine extracts the traveling unit A, the soyra 37 that is unwound while cutting the soil near the root vegetables in the field, and the root vegetable that has been unraveled by the sora 37 and transports the root vegetables. The transport device 24 is provided, and the soiler 37 includes a blade portion 37a that partially enters the soil, and an attachment portion 37b that attaches the blade portion 37a. The blade portion 37a extends vertically, and the blade portion 37a The one end portion 127 and the other end portion 128 in the vertical direction have different shapes, and the blade portion 37a is configured to be detachable so as to face upside down.

  Therefore, since the one end portion 127 and the other end portion 128 in the vertical direction of the blade portion 37a have different shapes, by attaching and detaching the blade portion 37a facing up and down, the difference in soil hardness and the resistance to pulling out root vegetables can be reduced. Depending on the difference in working conditions such as differences, the shape of the lower edge of the blade 37a entering the soil can be changed to change the strength of the soil-dissolving action, and the soil near the root vegetables in the field can be properly In other words, the root vegetables can be pulled out and transported well, and the harvesting operation can be optimized. Moreover, the upper side of the blade part 37a that does not enter the soil among the one end part 127 and the other end part 128 in the vertical direction of the blade part 37a performs the action of guiding the stems and leaves of the root vegetables, and the root vegetables of the adjacent cultivation strips. It is possible to harvest root vegetables of the cultivation strips that are harvested while untangling with the shoots and leaves of the plant, and the harvesting work can be optimized. Furthermore, the upper part of the blade part 37a can prevent the soil excavated by the soira 37 from falling on the root vegetables of the adjacent cultivation strip.

  Further, the front end edge of the vertical end portion 127 of the blade portion 37a is linearly extended in the vertical direction, and the front end edge of the vertical end portion 128 of the blade portion 37a is the lower end portion of the blade portion 37a. In a state where the blade portion 37a is mounted, the bent shape is such that the lower the curve portion is, the closer to the root vegetables in the field.

  Therefore, for example, when the soil is easy to collapse in sandy soil, soft soil, or root vegetables have a shape or size with a small pulling resistance, and the soil unraveling action may be weak, the front end The edge 37 in the vertical direction of the blade 37a having a straight edge is directed downward, the blade 37a is mounted, and the one end 127 having a straight edge in the front is plunged into the soil. It is possible to prevent the root vegetables in the field from being in an inappropriate posture or damaging the root vegetables by digging up the soil more than necessary. At this time, since the upper side of the blade portion 37a that does not enter the soil is bent to the side away from the root vegetables as it goes upward, the side away from the cultivation strip side that harvests the stems and leaves of the root vegetables of the adjacent cultivation strip It is possible to guide the entanglement with the stems and leaves of the root vegetables of the adjacent cultivation strip. On the contrary, for example, when the soil is sticky with clay, hard soil, or when the root vegetables have a shape and size with a high resistance to pulling out, and when strong soil disintegration is required The blade portion 37a is mounted with the other end portion 128 in the vertical direction of the blade portion 37a having a bent front end facing downward, and the other end portion 128 having a bent shape is plunged into the soil, thereby rooting the field. It is possible to obtain a strong soil unraveling action while digging up the soil in the lower part of the moss, to reduce the extraction resistance of the root vegetables by the extraction conveying device 24, so that the extraction of the root vegetables (for example, roots of root vegetables) is torn off I can suppress things.

  In addition, the blade portion 37a is attached to the vibration arm 33 that vibrates up and down via the attachment portion 37b, and the vertical end portion 127 and the front end edge of the other end portion 128 of the blade portion 37a are connected to the central portion in the vertical direction. It is configured so that it is not bent and arranged on the same straight line, and even when the blade portion 37a is mounted so that either one end 127 or the other end 128 is the upper part, the front end edge becomes the rear side position as it moves upward. Yes.

  Therefore, even when the blade portion 37a is mounted with the one end portion 127 in the vertical direction of the blade portion 37a facing downward, the blade portion 37a is mounted with the other end portion 128 in the vertical direction of the blade portion 37a facing downward. Even in the state, as the front edge of the upper portion of the blade portion 37a goes to the upper side, it becomes the rear side position, so that the stem and leaf portion of the root vegetable can be guided from below as the aircraft advances, and the root and leaf portion of the root vegetable of the adjacent cultivation strip The resistance to weed is relatively small, and the entanglement with the stems and leaves of the root vegetables of the adjacent cultivation strips can be well resolved.

  Further, the soy 37 is provided only on the side where the unharvested root vegetables are located with respect to the cultivation strip of the root vegetables to be harvested, and the soira 37 is not provided on the already harvested side with respect to the cultivation strip of the root vegetables to be harvested. Alternatively, another soiler having a vertical width smaller than that of the soiler 37 is provided.

  Therefore, since the soil excavated by the soira 37 is easily supplied to the already harvested side, it is possible to accurately prevent the soil excavated by the soira 37 from falling on the unharvested cultivation strip by the upper portion of the blade portion 37a.

  In addition, a pair of left and right soilers 37 are provided, and a pair of left and right vibrating arms 33 that vibrate up and down are attached to each blade portion 37a via each mounting portion 37b. A pair of left and right earth dropping members 39 for dropping the adhering soil are attached to the left and right vibrating arms 33 so that the distance between the pair of left and right earth dropping members 39 can be adjusted.

  Therefore, the distance between the pair of left and right earthmoving members 39 can be adjusted according to the shape and size of the root vegetables conveyed by the pulling and conveying device 24, and the root vegetables can be prevented from being conveyed by the pulling and conveying device 24 and the root vegetables can be improved. While transporting, the soil adhering to the root vegetables can be removed accurately, and the harvesting operation can be optimized.
