Fig. 10 is a front view of the alignment devices 54R and 54L in Fig. 9. 12 is a partially enlarged view from the front direction of the passage space of the foliage formed by the alignment devices 54R and 54L of FIG. 9, and FIG. 12 (a) shows a carrot having a size within a predetermined standard. (B) The figure has shown a mode that the ginseng of the minimum size smaller than a predetermined | prescribed standard passes. FIG. 13 is a partially enlarged view from the front direction of the passage space of the foliage portion as in FIG. 12, but shows a view in which the covering member 51 is assembled upside down, and FIG. 14 is a perspective view of the covering member 51. It is.

  The covering member 51 according to the first embodiment of the present invention has flat plate-like component mounting portions 51c and 51c positioned vertically as shown in the perspective view of FIG. From the vertical contact portion 51d, the cross-sectional structure is configured to be a U-shape when viewed from the front. The covering member 51 is composed of this U-shaped main body and a rotating covering member 51a that can turn toward the passage space of the foliage portion in the main body. The rotation covering member 51a has a handle shape having a U-shape when viewed from the front. When ginseng within a predetermined standard passes, the side surface of the U-shape at the bottom is a vertical contact portion 51d. The lower surface is in the same plane as the lower structure mounting portion 51 c of the covering member 51. Since the lower surface is in the same plane as the lower structure mounting portion 51c of the covering member 51, the structure mounting portion 51c regulates the rotation of the rotation covering member 51a. Further, the corner portion of the U-shape of the handle pattern has a structure with an R chamfer in front view so that the crop S is not damaged. The rotation covering member 51a protrudes about 2.5 mm toward the passage space of the foliage portion.

  An urging member 51 b that urges toward the inner and outer sides of the winding area is provided on the inner side of the winding end of the alignment endless body 48 at the upper part of the covering member 51. In the present embodiment, the urging member 51b is a spring. Further, the rotation fulcrum of the rotation covering member 51 a is provided on the inner side of the vertical contact portion 51 d, that is, on the side toward the winding region of the alignment endless body 48. The vertical and horizontal dimensions of the rotating covering member 51 a are ½ of the vertical and horizontal dimensions of the covering member 51, and the rotating covering member 51 a is disposed at the lower portion of the covering member 51 on the front side of the machine body. That is, the covering member 51 shown in FIG. 14 is attached to the right alignment device 54R.

  As shown in FIG. 12A, when the crop S of a predetermined standard passes, the rotation covering member 51 a rotates to the inside of the winding area of the alignment endless body 48 according to the crop S. In addition, as shown in FIG. 12B, for a crop of an extremely small size smaller than a predetermined standard, the lower part of the rotation covering member 51a rotates toward the passage space of the foliage part. Further, when it is known in advance that there is no extremely small-sized crop, as shown in FIG.

  The lower part of the contact surface of the foliage portion of the covering member 51 is constituted by a rotation covering member 51a that can turn toward the passage space of the foliage portion, and is energized by the urging member 51b, thereby passing through the space of the foliage portion. The width of the can be adjusted to the foliage of a tiny crop. Moreover, in the case of a crop larger than the minimum size, the foliage can push the rotation covering member 51a and rotate it to the inside of the winding region of the alignment endless body 48.

  Further, when the covering member 51 is turned upside down and attached to the alignment endless body 48, the lower side in contact with the shoulder portion of the crop can be configured not to rotate. The cutting position of the foliage can be aligned in a highly stable work form, and work efficiency is improved.

  The rotation covering member 51a constitutes the lower part of the front side of the contact surface of the foliage portion of the covering member 51, and the component mounting portion 51c of the covering member 51 is configured to restrict the rotation of the rotation covering member 51a. Thus, the rotation covering member 51a can be prevented from being excessively rotated in a direction away from the passage space of the foliage portion by being pushed by the foliage portion. This prevents the cutting position of the foliage part from being disturbed, eliminating the need for removing the foliage part of the crop, and reducing the labor of the operator.

  In the first embodiment, the horizontal dimension of the rotating covering member 51a is ½ of the horizontal dimension of the covering member 51. However, the entire lower part of the covering member 51 is composed of the rotating covering member 51a. Is also possible.

  9 to 11 show details of the alignment devices 54R and 54L to which the covering member 51 having the rotating covering member 51a is attached. As shown in FIG. 9, the rotation covering members 51a in the passage space of the foliage are arranged at positions that do not face each other. For example, an arrangement is made such that the rotation covering member 51a of the facing left alignment device 54L is not positioned at the position facing the rotation covering member 51a of the right alignment device 54R.

  Within the winding region of the alignment endless bodies 48, 48 and between the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47, the alignment endless bodies 48, 48 pass through the foliage from the winding area. The left and right guide guides 53, 53 that press toward the space are attached so that the position can be adjusted in the left-right direction. The left and right guide guides 53, 53 have a concavo-convex shape on the passage space side of the foliage portion, and the one concave portion faces the other convex portion. That is, the concave portion on the right alignment device 54R side is configured to face the convex portion on the left alignment device 54L side.

  Since the rotation covering member 51a of the facing covering member 51 is not positioned at the opposing position of the rotation covering member 51a in the passage space of the foliage part, the front and rear in the left and right alignment device 54 Since the foliage portion can be held between the three rotation covering members 51a, 51a, 51a of the rotation covering member 51a, 51a of the other and the rotation covering member 51a of the other alignment device 54, the foliage portion escapes. It is difficult and is held with an appropriate force. As a result, the cutting positions of the crops are easily aligned, so that the foliage of the crops is reliably removed.

  The passage space side of the foliage portion of the guide guides 53, 53 that presses the endless alignment bands 48, 48 from the inside toward the passage space of the foliage portion has an uneven shape, and one concave portion faces the other convex portion. With this configuration, when a crop whose stalk is enlarged by passing through passes, the alignment endless body 48 can be bent and escape to the concave portion, so that the alignment device is jammed regardless of the state of the crop. Is prevented and the work efficiency is improved.

  FIG. 15 shows a plan view of the alignment devices 54R and 54L constituting the foliage cutting part D according to the second embodiment of the present invention. In the second embodiment, the configuration of the guide guides 53, 53 provided in the winding region of the right and left aligned endless bodies 48, 48 is different from that of the first embodiment. In the second embodiment, the guide guide 53 is composed of a holding plate 53a along the longitudinal direction of the machine body and two or more pressing bodies 53b that press the alignment endless body 48. These pressing bodies 53b are provided across the holding plate 53a, and press the alignment endless body 48 by a spring disposed inside the holding plate 53a.

  The guide guides 53 and 53 are provided in the winding regions of the right and left endless endless bodies 48 and 48, respectively, and the pressing bodies 53b that are located on the left and right sides of the passage space of the foliage are arranged at positions that do not face each other. To do.

  By pressing the alignment endless band 48 from within the winding region with two or more pressing bodies 53b,... When the thick foliage part passes, the pressing body 53b may escape in the direction of retreating from the passage space of the foliage part. Since the width of the passage space of the foliage portion is maintained at a width suitable for aligning the cutting position of the crop S, the foliage cutting accuracy is improved.

  Since the pressing bodies 53b located on the left and right sides of the passage space of the foliage part are not in positions facing each other, the passage space of the foliage part opens too much and the crop S falls off downward. In addition, since the foliage can be prevented from being clogged by the left and right pressing bodies 53b,..., The foliage cutting accuracy is improved, and the work efficiency is improved.

  In FIG. 16, the perspective view of the coating | coated member 51 in the foliage cutting part D concerning 3rd embodiment of this invention is shown. FIG. 16 shows a diagram in which the members are separated in order to show a method for assembling the members constituting the covering member 51 and the like.

  In the third embodiment, the base body 150 is provided on the constituent body 48 a of the alignment endless body 48. The base body 150 is provided with two sliding struts 151 extending in parallel from the constituent body 48a to the outside of the winding region of the alignment endless body 48. On the covering member 51 side, a connecting cylinder 152 into which the sliding support column 151 is inserted is provided toward the inside of the winding area of the alignment endless body 48 of the vertical contact portion 51c. A locking hole 153 that is a parallel circular hole is bored in the sliding column 151 so as to be perpendicular to the axis of the sliding column 151, and a long locking hole is formed in the coupling cylinder 152 in the axial direction of the coupling cylinder 152. Wear 154. The connecting cylinder 152 is fitted with a space adjusting urging member 155 that is a spring.

  The covering member 51 is assembled by inserting the sliding column 151 into the connecting cylinder 152, passing the lock long hole 154, and inserting the fixing member 156, which is a parallel pin, into the lock hole 153. The lock hole 153 and the fixing member 156 are brought into close contact with each other, and the lock long hole 154 and the fixing member 156 can be relatively operated. With this configuration, the relative position between the structural body 48a and the covering member 51 provided in the structural body 48a can be changed.

  By passing the lock long hole 154 and inserting the fixing member 156 into the lock hole 153, the relative position between the structural body 48a and the covering member 51 provided in the structural body 48a can be changed. Thus, the operating range of the covering member 51 can be restricted and the covering member 51 can be prevented from coming off.

  Further, by providing the space adjusting biasing member 155 on the outer periphery of the connecting cylinder 152, the covering member 51 can be retracted to the aligned endless belt 48 side when the thick foliage portion passes, so that the foliage portion Is prevented from clogging the alignment device 54, and the work efficiency is improved.

The remaining leaf processing section E is configured by configuring the remaining leaf processing conveyor 76 that transports the remaining leaves from the outside of the machine body to the left and right inside directions while processing the remaining leaves.

  The remaining leaf processing conveyor 76 is inclined about 2 to 5 degrees from the left and right sides of the machine body to the other side. Thereby, since the carrot which fell is moved by the drive and inclination movement of the remaining leaf processing belt 74, the movement of the carrot does not stop on the remaining leaf processing conveyor 76, and it is necessary to move the carrot stopped manually. No work efficiency is improved. Further, since the residual leaf processing conveyor 76 is slightly inclined (about 2 to 5 degrees), the residual leaf processing conveyor 76 is inclined with respect to the ground even if the aircraft is inclined to the left and right sides depending on the state of the field. Since the carrot remains in a substantially horizontal state, the carrot does not stagnate on the remaining leaf processing conveyor 76 or move in the direction opposite to the conveying direction of the remaining leaf processing conveyor 76, and such carrot is transported manually. There is no need to return to the route and work efficiency is improved.

  With the above configuration, since the remaining leaf processing roller 75 constituting the remaining leaf processing conveyor 76 cuts off the remaining leaves of carrots cut by the stem and leaf cutting device 61, the operation of manually cutting the remaining leaves after the harvesting operation is omitted. Work efficiency can be improved.

  In addition, the remaining leaf processing belt 74 constituting the remaining leaf processing conveyor 76 is made of an elastic body such as rubber or urethane, so that the remaining leaf processing belt is removed even if carrots fall after the leaves are cut off by the foliage cutting device 61. Since 74 reduces the impact of the drop, the carrot is prevented from being damaged by the impact of the drop, and the quality of the carrot is improved.

The hanger arms 95, 95 are configured to be movable upward or downward only when a moving force greater than the resistance force is applied upward or downward due to the frictional resistance of the frictional resistors 94, 94 sandwiched therebetween.

  A hanger frame 96 that protrudes in the front-rear direction from the front-rear end of the body of the sorting and conveying conveyor 87 is attached to the ends of the hanger arms 95, 95 in the front-rear direction. A pair of front and rear hanging hangers 98 and 98 for hanging and supporting a container (flexible container bag) 97 for hanging and supporting four points on the front, rear, left and right are attached so as to be rotatable in the left-right direction. Further, upside-down inverted U-shaped (saddle-shaped) outer suspension bodies 99a, 99a are welded to the outer end portions of the hanging hangers 98, 98, respectively, and the inner end portions of the aircraft body are downwardly U-shaped. The inner suspension bodies 99b, 99b of the mold are welded, and the suspension hooks 99f, 99f, 99f, 99f for suspending the container 97 on the outer suspension bodies 99a, 99a and the inner suspension bodies 99b, 99b are movable up and down. Attach to.

  Instead of welding the outer suspension bodies 99a, 99a and the inner suspension bodies 99b, 99b, the outer ends of the hanging hangers 98, 98 are bent into an inverted U shape (saddle shape), and the inner ends of the aircraft It is good also as a structure which can be attached to the hanging hooks 99f, 99f, 99f, and 99f movably up and down by bending a U-shape.

  A detailed configuration of the hanging hook 99f is shown in FIG. FIG. 17A shows a perspective view of the hanging hook 99f, and FIG. 17B shows a side view from the T direction. The hanging hook 99f is a ring having a substantially square shape as a whole, and is composed of two vertical bars and two horizontal bars in FIG. Further, the hanging hook 99f includes a hook body 160 and a rotating part 161 having the one vertical bar of the hook body 160 as a rotation center. An upper and lower sliding member 164 is provided between the hook body 160 and the rotating part 161 to smooth the operation of the rotating part 161, and an urging member 162 which is a spring, and a spring provided on the hook body 160 The rotating part 161 is biased by the hook body 160 by the receiver 163, and the rotating part 161 is rotated to open the hanging hook 99f, and then the hanging hook 99f is automatically closed. The opening part of the hanging hook 99f has notches at both ends of the hook body 160 and the rotating part 161, and the two are combined to form a single rod-like body. With this configuration, the rotation direction of the rotation part 161 can be determined. Further, the end portion of the spring 163 faces the outward direction of the hanging hook 99f so as not to damage the container 97.

  The hanging hangers 98, 98 are arranged at the four corners of the housing container 97 at the front and rear outer suspension bodies 99a, 99a and the front and rear so that the upper opening of the housing container 97 to be suspended is substantially rectangular in plan view.

The protrusion 101 is attached.

  Further, a hole (not shown) in which a female screw is engraved is formed on the rear side or both front and rear sides of the rotating shaft 93, and an adjustment knob 102 in which a male screw (not shown) to be screwed into the hole is engraved. By inserting and rotating the adjustment knob 102 to change the front-rear distance between the second selection frames 78 and 78 and the hanger arms 95 and 95 sandwiching the friction resistors 94 and 94, the frictional resistance is changed. The configuration is as follows.

  If the adjustment knob 102 is provided at the rear end portion of the rotating shaft 93, the auxiliary operator who is on the auxiliary work seat 91 can easily operate. If the adjusting knob 102 is provided at the front end portion of the rotating shaft 93, the control seat 11 is mounted. This makes it easy for the operator to operate and makes it easy to adjust the frictional resistance of the frictional resistors 94 and 94.

  Further, a slide shaft 103 that is slidable in the front-rear direction is provided below the second transport frame 78 on the transport end side of the sorting transport conveyor 87 and on the rear side of the machine body with respect to the rotating shaft 93. A spring 104 for applying tension pressure in the front direction of the machine body is attached to the shaft. An auxiliary hook 105 is provided at the front end of the body of the spring 104 so as to prevent the slack by hanging the front and rear intermediate portions of the container 97 entering the lower part of the sorting and conveying conveyor 87, and the rear side of the slide shaft 103. A slide knob 106 is attached at the end and on the outside of the second frame 78 so that the auxiliary operator grasps it by hand and slides the slide shaft 103 back and forth.

  If the slide shaft 103 is provided from the rear end portion of the machine body of the sorting / conveying conveyor 87 to the same position as the front / rear intermediate portion or slightly to the front side of the machine body when not operated, the position of the auxiliary hook 105 can be easily adjusted. Further, the slide shaft 103 may be provided from the front side to the rear side of the machine body. In this case, an operator who is on the control seat 11 can operate the slide shaft 103.

  Then, as shown in FIG. 6, a hanging band hook 107 for hooking a hanging band 97 i inside the body of the container 97 below the sorting and conveying conveyor 87 and on the upper side in the conveying direction of the sorting and conveying conveyor 87 than the rotating shaft 93. And the hanger pin 108 for hooking the hanger 97o on the outer side of the machine body is disposed on the hanger frame 96 so as to face the upper side of the machine body. The suspension bands 97i, 97o on the outside of the machine body are members for hanging the container 97 containing carrots by hanging it on a forklift or hoist.

Next, operation | movement of the said accommodating part G is demonstrated.
At the start of the carrot harvesting operation, the sorting and conveying conveyor 87 is lowered to the lowest position in order to minimize the falling distance of the carrot from the conveying terminal end of the sorting and conveying conveyor 87 to the storage container 97. Further, the four corners of the storage container 97 are hooked on the suspension hooks 99f, 99f, 99f, 99f provided on the outer suspension bodies 99a, 99a and the inner suspension bodies 99b, 99b of the front and rear suspension hangers 98, 98, respectively. The opening has a substantially rectangular shape in plan view. Then, the front and rear hanger arms 95 and 95 are rotated upward until they contact the upper limit restricting protrusion 101, and the front and rear hanging hangers 98 and 98 are inclined upward from the body inner end toward the body outer end. To do. As the hanging hangers 98 and 98 are inclined upward toward the outer side of the machine body, the suspended storage container 97 is also inclined upwardly from the inner edge part of the machine body toward the outer edge part of the machine body. Become posture.

  At this time, among the suspended containers 97, the inner side of the machine body from which the carrots are discharged from the transfer terminal end side of the sorting and conveying conveyor 87 is slackened, so the vertical length is shortened, and the outer side of the machine body is hardly slackened so Length increases. In addition, the storage container 97 shall be comprised flexibly with cloth material, synthetic fiber, etc.

  Further, the outer end portion of the machine body of the discharge shooter 89 is inserted into the inner end portion of the storage container 97, and the inner end portion of the storage container 97 is inserted into the lower side of the sorting end of the sorting and conveying conveyor 87. Auxiliary hook 105 is hooked in a suspension hole (not shown) formed at a substantially central portion in the front-rear direction. Further, the suspension band 97 i on the inner side of the body of the container 97 is hooked on the suspension band hook 107, and the suspension band 97 o on the outer side of the body is hooked on the suspension band pin 108 on the hanger frame 96.

  The hanger arms 95 and 95 are held in an inclined posture set by the operator due to the frictional resistance of the frictional resistors 94 and 94. However, if the hanger arms 95 and 95 are left unattended, the adjustment knob 102 is rotated. Thus, the frictional resistance force of the frictional resistance bodies 94 and 94 disposed between the second transport frames 78 and 78 and the hanger arms 95 and 95 is adjusted. When the adjustment knob 102 is rotated in the tightening direction, the contact area and the contact pressure of the friction resistors 94 and 94 are increased, the friction resistance is increased, and the hanger arms 95 and 95 are prevented from moving freely. In addition, if it rotates in the loosening direction, the contact area and the contact pressure of the frictional resistance bodies 94 and 94 will decrease, and a frictional resistance force will become weak. Further, when the harvesting operation proceeds and the amount of carrots stored in the storage container 97 exceeds a certain amount, the auxiliary operator steps on the ascending pedal 92a and extends the elevating cylinder 88 to extend the conveying terminal portion of the sorting and conveying conveyor 87. Raise the side.

  While the sorting and conveying conveyor 87 is moving up, the hanger arms 95 and 95 are lowered because the force that the hanger arms 95 and 95 try to move down exceeds the friction resistance of the friction resistors 96 and 96. The lowering of the hanger arms 95, 95 occurs only while the sorting / conveying conveyor 87 is raised so as to secure a carrot storage space in the storage container 97.

  When the hanger arms 95 and 95 are rotated downward, the hanging hangers 98 and 98 are rotated with the hanger frame 96 as a fulcrum, the outside of the body of the hanging hanger 98.98 is rotated downward, and the inside of the body is Rotate upward. Since the outer side of the body of the container 97 is positioned upward at the stage of installation, the position hardly changes, but the inner side of the body is pulled upward by the movement of the hanging hangers 98 and 98. Thereby, the slack which had arisen inside the machine body of the storage container 97 is eliminated according to the rising amount. It should be noted that there is almost no change in the drop between the transfer terminal end of the sorting transfer conveyor 87 and the storage container 97 due to this operation, and the end of the discharge shooter 89 hangs down into the storage container 97, so that the storage container It does not protrude from 97.

  Further, every time the harvesting operation proceeds and the amount of carrots stored in the storage container 97 exceeds a certain amount, the transport terminal end of the sorting transport conveyor 87 is raised, the hanger arms 95, 95 are rotated downward, and the storage container 97 The inside of the fuselage is pulled upward to secure a space for storing carrots in the storage container 97, and the carrot piles biased toward the inside of the fuselage are destroyed.

  Then, when the sorting and conveying conveyor 87 is rotated upward and the hanging hangers 98 and 98 are in a substantially horizontal posture, the slack on the inner side of the machine body of the storage container 97 is eliminated, and the vertical height on the inner side and the outer side of the machine body is substantially the same. Become. In this state, since approximately 200 kg of carrots are stored in the storage container 97, the operator stops traveling of the machine body and lowers the storage container 97 outside the apparatus. At this time, the hanger arms 95 and 95 are configured to contact the lower limit restricting protrusions 100 and 100.

  When the storage capacity of the storage container 97 is full, the machine body, the pulling / conveying device 24, the sorting transport conveyor 87, etc. are stopped, and the storage container 97 is removed from the hanging hooks 99f, 99f, 99f, 99f and the slide knob 106 is removed. The auxiliary hook 105 is removed from the storage container 97 by pulling backward from the machine body. When the hand is released from the slide knob 106 due to the tension pressure of the spring 104, the auxiliary hook 105 automatically returns to the sorting / conveying conveyor 87 and the substantially central portion in the front-rear direction of the storage container 97 at the time of mounting.

  Further, by operating the operation handle to lower the mounting table forward or backward, the storage container 97 in which carrots are stored slides down the mounting table under its own weight. Therefore, when the storage container 97 is lowered to the front side of the machine body When the storage container 97 is lowered to the rear side of the machine body, the storage container 97 containing about 200 kg of carrots is lowered from the storage part G and installed in the field. When the harvesting operation is completed, the hanger arms 95 and 95 are again brought into contact with the upper limit restricting protrusion 101, and the sorting and conveying conveyor 87 is rotated upward to the uppermost position.

  With the above-described configuration and operation, there is almost no slack on the outer side of the container 97 from the start of work to the time of replacement, so it is prevented that carrots enter the slack and reduce the capacity of the container 97. The frequency of replacing the container 97 is reduced, the work efficiency is exchanged, and the labor of the operator is reduced.

  With the conventional method of attaching the storage container, slack is generated on both sides of the machine body. Carrots enter this slack, and even if the storage container is lifted, the slack cannot be removed. The frequency was high.

  In addition, the slack generated in the storage container was eliminated by moving the sorting transport conveyor up and down, and the storage space could be secured, but every time the slack was removed, the operator had to operate the sorting transport conveyor, The work efficiency was reduced. In particular, in the case of an auxiliary worker who performs sorting, the sorting accuracy during operation has been reduced. And since the difference between the transfer end of the sorting conveyor 87 and the left and right sides of the container 97 is almost constant, the carrot can be prevented from being damaged by the impact of the drop, and the product value of the carrot is improved. To do. Further, normally, the rotation of the hanger arms 95 and 95 is regulated by the frictional resistors 96 and 96, and the hanger arms 95 and 95 are configured to rotate downward only while the sorting and conveying conveyor 87 is raised. Since the inside of the hanging hangers 98 and 98 can be moved upward in conjunction with the operation of the sorting and conveying conveyor 87 in accordance with the change in the amount of ginseng in the container 97, the amount of the container 97 is automatically adjusted. Since the slack inside the machine body of the container 97 is automatically eliminated, it is not necessary to move the sorting / conveying conveyor 87 up and down to remove the slack, and the work efficiency is remarkably improved.

  In addition, by providing an upper limit restricting projection 101 that determines the upper inclination posture limit of the hanger arms 95, 95 on the second transport frame 78 on the front side of the machine body, the operator can easily understand the position where the hanger arms 98, 98 are set, The positions of the hanger arms 95, 95 can be determined so that the container 97 is full.

  In addition, since the upper limit restricting protrusion 101 is provided only on the second transport frame 78 on the front side of the machine body, the upper limit restricting protrusion 101 is within the working range of an auxiliary worker who sorts the carrots being transported by the sorting transport conveyor 87. Since it does not exist, it is possible to prevent the auxiliary worker from colliding or getting caught on clothes, and the burden on the worker is reduced.

  The lower limit regulating members 100 and 100 are also provided on the second transport frame 78 on the rear side of the machine body. However, the lower limit regulating members 100 and 100 are located at the inner end portions of the machine bodies of the hanging hangers 98 and 98, and the normal sorting operation is finished. Since there is no interference with the operation of the auxiliary worker, there is no problem. In addition, in order to prevent the operator from forgetting to bring the hanger arms 95, 95 into contact with the upper-stage restricting protrusion 101, forgetting to set can be prevented by writing a note on the second transport frame 78 on the rear side.

  The outer suspension bodies 99a and 99a are provided upward at the outer end portions of the hanger 98 and 98, and the inner suspension bodies 99b and 99b are provided at the inner end portions of the suspension hangers 98 and 98. Since the lower hooks 99f and 99f are positioned below the hanging hooks 99f and 99f on the outer side of the machine body, when the storage container 97 is installed, the difference in height between the outer side of the machine body and the inner side of the machine body increases. Further, ginseng is more difficult to spill from the outside of the body of the container 97. Further, when the left and right end portions of the hanging hanger 98 are bent to form the outer suspended body 99a and the inner suspended body 99b, it is possible to reduce the cost because it can be constituted by a single bar.

  Then, the hanging band 97i provided on the inner side of the container 97 is hooked on the hanging band hook 107 below the sorting and conveying conveyor 87, and the hanging band 97o provided on the outer side of the machine body is hooked on the hanging band pin 108 on the hanger frame 96. As a result, the suspension band 97i, 97o pulls the storage container 97, so that slack in the storage container 97 can be reduced.

  Further, by hooking the auxiliary hook 105 into the hole at the substantially central portion in the front-rear direction of the storage container 97, it is possible to reduce the slack generated in the substantially central portion in the front-rear direction inside the body of the storage container 97. It is hard to get into the slack of the room, and sufficient storage space can be secured. When the slide knob 106 is pulled to the rear of the machine body, the slide shaft 103 slides to the rear of the machine body, and the auxiliary hook 105 is detached from the storage container 97. Therefore, the container 97 and the sorting and conveying conveyor 87 filled with carrots are transported. Since the auxiliary hook 105 can be removed without entering the narrow space between the lower end portion and the end portion, the work efficiency is improved and the labor of the operator is reduced.

  Further, when the hanger arms 95 and 95 are brought into contact with the upper limit restricting projection 101 and the sorting and conveying conveyor 87 is rotated to the uppermost position, the hanging hangers 98 and 98 are rotated and the outer ends of the hanging hangers 98 and 98 are outside the machine body. Since the portion is located on the inner side of the end of the body frame 1, the hanging hangers 98, 98 protruding from the body frame 1 do not collide with walls or the like, and the body is prevented from being damaged.

Further, since the end portion of the discharge chute 89 is hung down inside the storage container 97, there is no space where the carrot between the discharge chute 89 and the storage container 97 can fall, so that the discharge from the sorting and conveying conveyor 87 is discharged. Carrots can be prevented from falling and the product value of the carrots is improved.
If the width of the discharge shooter 89 in the longitudinal direction of the machine body is substantially the same as the width of the sorting and conveying conveyor 87 in the longitudinal direction of the machine body, the effect of preventing the carrot from falling is further improved.

Next, the configuration of the placement discharge unit H will be described.
As shown in FIG. 1 to FIG. 6, a folding support frame 109 is provided at the rear side of the left and right sides of the body frame 1 through the folding rotation shaft in the longitudinal direction of the body, and the body of the folding support frame 109 is installed. A mounting frame 110 is attached to the rear end side so as to be rotatable in the left-right direction of the machine body with the folding rotation shaft as a rotation fulcrum. In addition, a rotation support joint is rotatably provided by penetrating the folding rotation shaft on the front side of the body from the mounting frame 110, and below the position where the rotation support joint penetrates the folding rotation shaft. A cavity is formed.

  A bearing having a diameter in close contact with the inner surface of the cavity is provided in the cavity of the pivot support joint so as to be inclined toward the body frame 1 side, and a discharge pivot shaft is provided on the bearing on the other side of the body (the body frame 1). It is attached in an upward inclined posture that is located upward as it is farther from the side. Further, the left and right mounting side walls that hold the left and right sides of the container 97 on the base side (one side of the machine body on the left and right sides) and the end part side (the other side of the machine body on the left and right sides) of the upwardly inclined discharge rotation shaft and prevent the container 97 from falling. 113 and 113 are provided so as to be rotatable in the vertical direction, respectively, and a rear portion of the container 97 that is suspended by the hanging hangers 98 and 98 is provided between the left and right sides of the rear end portions of the left and right mounting side walls 113 and 113. A holding rear wall 114 for holding is provided. The mounting rear wall 114 and the left and right mounting side walls 113 and 113 may be welded and connected, or a metal plate may be integrally formed to form a U-shaped mounting wall in plan view.

  Further, a flat plate-shaped receiving plate 115 that receives the bottom of the storage container 97 is provided between the left and right of the mounting side walls 113, 113 and on the front side of the mounting rear wall 114. And the reinforcement bar 116,116,116 which reinforces the receiving plate 115 is provided in the front-and-rear end part of this receiving plate 115 and the bottom face of the front-back direction substantially center part, respectively, and the bottom part of the storage container 97 which accommodates ginseng is supported. At the same time, a mounting bucket 117 is configured to rotate downward using the discharge rotation shaft as a rotation fulcrum and to slide the storage container 97 down to the field.

  If the left and right width of the receiving plate 115 is longer than the left and right width of the hanger arms 95, 95, even if the receiving container 97 is inflated by the carrot in which it is stored, it will fit within the left and right width of the receiving plate 115, Since the storage container 97 can be prevented from protruding from the mounting side walls 113, 113, the storage container 97 protruding from the receiving table 115 is prevented from coming into contact with the radiator cover 10 a or the like of the control unit B and is prevented from being damaged. In addition, the carrot falls from the damaged part and is damaged, and the commercial value is prevented from deteriorating.

  Further, the operation support plate 118 in a posture inclined upward toward the rear of the machine body is fixed to the left and right other ends of the installation frame 110 in the posture described above at a right angle with respect to the discharge rotation shaft. The lower end portion of the rotation plate 119 is pivotally attached to the left and right other end portions of the machine body so as to be rotatable in the longitudinal direction of the machine body with the discharge rotation shaft as a rotation fulcrum. A hole that is long in the front-rear direction is formed on the upper side of the rotating plate 119.

  Then, between the hole formed in the rotating plate 119 and the upper part of the operation support plate 118, a screw groove is cut on the surface of one bar, and a screw groove is cut on the inner surface of the other hollow bar. The mounting discharge unit H is provided by providing a screw rod 120 configured by combining the screw grooves of the rods of each other, and attaching an operation motor 121 that rotates and extends the screw rod 120 to the rear end portion of the screw rod 120. Is configured.

  When operating members such as switches and levers for operating the operating motor 121 are provided on the control panel 12, it is easy for the operator to operate according to the instructions of the auxiliary operator, and when provided on the operation support plate 118, the auxiliary operator is provided. However, it becomes easy to operate while lowering the storage container 97, and work efficiency is improved. Further, the screw rod 120 may be replaced with a telescopic member such as an electric cylinder or a hydraulic cylinder.

  The placement bucket 117 is arranged in an upwardly inclined posture in which the discharge turning shaft serving as a turning fulcrum of the placement bucket 117 is located upward on the left and right sides of the machine body, and the placement bucket 117 is rotated upward as much as possible. When the mounting bucket 117 is rotated downward, the front end of the mounting bucket 117 moves away from the body frame 1 to the left and right sides of the body. It is set as the structure to do.

  With the above configuration, during the harvesting operation, the mounting bucket 117 can be rotated to the left and right sides of the machine body to support the bottom of the container 97, and after the work is completed, the mounting bucket 117 is rotated to the left and right sides of the machine body. Since it can be folded by moving it, the left and right width of the aircraft is compact, the aircraft can be easily placed on transport means such as a light truck, and it can be accommodated in a storage location such as a warehouse without taking up too much space it can.

  Moreover, since the discharge rotation shaft is folded and disposed below the rotation shaft, the upper end portion of the rotation support joint can be disposed at substantially the same position as the upper end portion of the body frame 1 and the boarding step 90. The rotation support joint does not prevent the auxiliary worker from getting in and out of the body frame 1 and the boarding step 90, the work efficiency is improved, and the auxiliary worker does not hit the foot and cause injury or rolling. , Improve safety.

  In addition, the discharge rotation shaft is arranged in an upwardly inclined posture that is positioned upward on the left and right other sides of the machine body, and when the mounting bucket 117 is rotated upward as much as possible, the posture becomes substantially parallel to the field scene, When the mounting bucket 117 is rotated downward, the container 97 is separated from the machine body by being configured to be separated from the machine body frame 1 to the left and right sides of the machine body as the front end of the placement bucket 117 is lowered. Since it can be lowered in the direction, particularly in the direction away from the radiator cover 10a projecting from the left and right outer sides of the control part B, it is possible to prevent the storage container 97 being lowered on the field from coming into contact with the radiator cover 10a and the like. The operator picks up the carrot without the impact of contact between the radiator 97 and the radiator cover 10a or the carrot stored by the container 97 being broken by contact. Mel is not necessary.

  In particular, when the storage container 97 is damaged, an alternative storage container 97, a container, or the like must be prepared, and the carrot stored in the damaged storage container 97 must be transferred. Labor must be expended, and there is a risk that the spare container 97 will be insufficient and the carrot harvesting operation in the field may not be completed. However, this configuration can solve this problem. . In addition, preventing the carrot from falling from the container 97 can prevent the carrot from being damaged by the impact of the drop, thereby improving the commercial value of the carrot.

  Further, since the storage container 97 lowered to the field is located further to the left and right sides of the machine body than the outer end of the mounting bucket 117, when the storage container 97 is lowered and returned to the carrot pulling and harvesting operation, the storage container 97 is mounted on the field. Since the distance for separating the airframe can be shortened in order to avoid the storage container 97, the work efficiency is improved, and it is prevented that the unharvested carrots planted on the adjacent strips are crushed, Ginseng yield and commercial value are improved.

  When the storage container 97 is lowered to the field toward the front side of the machine body and returned to the pulling and harvesting operation, the machine body is first moved backward to securely separate the storage container 97 from the mounting bucket 117, and then the machine body is advanced. When the placement bucket 117 located at the end of the left and right sides of the machine body is retracted to a position where it does not contact and moves forward, and there is no possibility of contacting the storage container 97, an operation to return to the carrot harvesting line is performed.

  The space between the machine body frame 1 and the mounting bucket 117 is increased as the mounting bucket 117 is rotated downward, so that the container 97 is operated while the operator manually operates the speed change operation lever 13 in the reverse direction. When lowering the container, it is possible to work by entering one space to one foot in this space, so that the distance between the machine going backward and the operator is difficult to be separated, and the container 97 can be safely lowered to the field. it can.

In addition, in the case of an interval enough to insert one body, the operator can operate the machine body without leaving the control unit B until the storage container 97 reaches the farm field, so that safety is further improved.
Further, since the storage container 97 can be discharged in the direction away from the machine body, the storage container 97 that is lowered to the farm field even if the length of the mounting frame 110 protruding to the left and right sides of the machine body is shortened is the control unit B. Since it is configured not to contact the radiator cover 10a and the like, and the center of gravity of the mounting / discharging part H can be brought close to the center part in the left-right direction of the aircraft, the weight balance of the aircraft is stable, and the straightness and maneuverability are improved. The drawing efficiency is improved and the work efficiency is improved.

  In addition, since the left and right widths of the airframe are shortened, the airframe can be configured compactly, so that the airframe can be easily stored, and the mounting / discharging portion H is less likely to come into contact with a bag or a wall during turning. Efficiency is improved.

  The left and right mounting side walls 113, 113 and the mounting rear wall 114 are provided on the left and right sides of the receiving plate 115 and the upper part of the outer edge of the receiving plate 115. Since the container 97 can be prevented from falling from the mounting bucket 117, the carrot is prevented from being damaged by the impact of the drop, the product value of the carrot is maintained, and the receiving plate 115 is disposed below the container 97. It is possible to prevent the enormous weight of the storage container 97 that has been reduced by supporting the hanger 98 and 98 from being hung on the hanging hangers 98 and 98, the hanger arms 95 and 95, and the like, thereby improving durability.

  Further, since the operator operates the operation member 121a to drive the operation motor 121 to expand and contract the screw rod 120 that rotates the mounting bucket 117 up and down, the operator can move the mounting bucket 117. Since it is not necessary to spend a force on the vertical rotation, the work efficiency is improved and the labor of the operator is reduced.

  Further, by providing the operation support plate 118 to which the screw rod 120 is attached at a right angle with respect to the discharge rotation axis, the mounting bucket 117 can be rotated at a constant speed in accordance with the expansion and contraction of the screw rod 120. As a result, the rotating operation of the loading bucket 117 is not wasted, the work efficiency is improved, the overload is hardly applied to the discharge rotating shaft, and the durability is improved.
