When the holding members 112 and 112 in a lowered state are provided so as to be positioned above the upper end surface, the claw portions 112a and 112a of the holding members 112 and 112 are prevented from obstructing the conveyance of the container 107, and the container 107 is received. 100 can be smoothly sent to the storage table 104.

A detailed configuration of the lift device 106 will be described below.
Between the engine cover 7 and the cockpit 11 located on the left side of the root vegetable harvesting machine and the storage platform 104 and the container transfer device 114 located on the right side of the root vegetable harvesting machine, a pair of front and rear U-shaped pairs The first support frames 120 and 120 and the pair of front and rear second support frames 122 and 122 that are U-shaped in plan view and are adjacent to the pair of front and rear first support frames 120 and 120, respectively. A frame of the lift device 106 is formed by the support frame 120 and the second support frame 122. The right side surface of each first support frame 120 and the left side surface of each second support frame 122 are fixed to each other, and the front and rear support frames 120 and 122 are integrally formed.

A connecting plate 124 for connecting the front and rear first support frames 120 and 120 is provided at the lower end of the first support frames 120 and 120, and the inner space of the front and rear first support frames 120 and 120 is provided at both front and rear ends. A first support shaft 128 with a bearing 126 attached thereto is provided, and a pair of front and rear sprockets (may be pulleys) 130 are rotatably mounted on the first support shaft 128.
The first bearing 126 is slidable in a first bearing groove 127 provided in the first support frame 120.

  Further, in the inner space of the front and rear second support frames 122, 122, a second support shaft 134 having second bearings 132 attached to both front and rear ends is provided, and a pair of front and rear bosses 136 are attached to the second support shaft 134. A pair of front and rear L-shaped holding members 112, 112 are provided below the boss 136 so as to be slidable in the direction. The second bearing 132 is slidable in a second bearing groove 133 provided in the second support frame 122.

  A turnbuckle 138 that expands and contracts by rotating is provided between the front and rear holding members 112 and 112, and the distance between the front and rear holding members 112 and 112 can be changed by the expansion and contraction of the turnbuckle 138. Specifically, the turnbuckle 138 has a thread groove formed on the inner side of a pair of front and rear hollow moving rods 138a and 138a fixed to the front and rear holding members 112 and 112, respectively. What is necessary is just to set it as the structure which inserted and connected the both ends of the chopped rotating rod 138b in a pair of front and rear moving rods 138a and 138a.

  The screw groove of one of the front and rear moving rods 138a is a right screw, and the screw groove of the other moving rod 138a is a left screw (reverse screw). Further, the screw groove is made different between the front and rear of the rotating rod 138b (one is a right-handed screw and the other is a left-handed screw), and the right screw side end of the rotating rod 138b is inserted into the right-handed moving rod 138a. The left screw side end of the rotating rod 138b is inserted into the left screw moving rod 138a. With such a configuration, when the rotating rod 138b rotates, the left and right moving rods 138a, 138a move inward or outward, the turnbuckle 138 expands and contracts, and the distance between the front and rear holding members 112, 112 changes.

Further, the rotating mechanism of the rotating rod 138b of the turnbuckle 138 may be as follows.
The driven sprocket 140 is pivotally attached to the vicinity of the front and rear center of the rotating rod 138b of the turnbuckle 138 (the portion where there is no thread groove at the switching portion between the right screw and the left screw), and further, the forward / reverse motor 144 is mounted below the second support shaft 134. And a drive sprocket 148 is provided on the output shaft 146 of the forward / reverse motor 144. Then, the transmission chain 150 is wound between the driven sprocket 140 and the driven sprocket 148 that are axially attached to the rotating rod 138b of the turnbuckle 138. Since the rotating rod 138b pivotally mounted on the sprocket 140 rotates, the turnbuckle 138 expands and contracts, and the distance between the front and rear holding members 112, 112 changes.

These turnbuckles 138, driven sprockets 140, forward / reverse motors 144, drive sprockets 148, etc. constitute a front-rear interval changing mechanism for the holding members 112, 112 of the lift device 106.
Thus, since the pair of front and rear holding members 112, 112 of the lift device 106 can move in the front-rear direction, the container 107 having a slightly different size can be obtained by changing the distance between the front and rear holding members 112, 112. Can also respond.

  Further, the holding state of the container 107 is released by widening the space between the holding members 112 and 112 from the state in which the holding members 112 and 112 of the lift device 106 hold the upper container 107, thereby releasing the upper container 107. It can be loaded on the container 107. Therefore, the multistage stacking of the containers 107 can be easily achieved, and the work efficiency is improved.

  Further, a third support shaft 142 is provided on the left side of the front and rear first support frames 120 and 120 (on the side opposite to the second support frames 122 and 122) so as to be fixed to the first support frames 120 and 120. ing.

  The third support shaft 142 and the second support shaft 134 are provided with protrusions 142a and 134a projecting upward, respectively, and the protrusions 142a of the third support shaft 142 and the protrusions 134a of the second support shaft 134 are for lifting the container 107. Both ends of the lifting chain 152 (which may be a wire) are connected. As shown in FIGS. 10 to 12, the lifting chain 152 is provided across the projection 142 a of the third support shaft 142, the sprocket 130 of the first support shaft 128, and the projection 134 a of the second support shaft 134.

  Further, a retractable cylinder 154 is provided between the lower portion of the first support shaft 128 and the connecting plate 124. The cylinder 154 may be a known one, and may be a hydraulic type, a pneumatic type or an electric type.

7 shows the state of the lift device 106 when the cylinder 154 is contracted, and FIG. 8 shows the state of the lift device 106 when the cylinder 154 is extended. FIG. 9 is a block diagram of the control device (CPU) 158 of the root vegetable harvester shown in FIG.
When the cylinder 154 is contracted, the first bearings 126 at both ends of the first support shaft 128 are positioned at the lower end in the first bearing groove 127, and the second bearings 133 at both ends of the second support shaft 134 are second. It is located at the lower end in the bearing groove 134. When the cylinder 154 extends, the first support shaft 128 that moves up and down according to the expansion and contraction of the cylinder 154 is lifted upward, and the lifting chain 152 wound around the sprocket 130 of the first support shaft 128 is also pulled upward. The sprocket 130 rotates. Since the third support shaft 142 connected to one end of the lifting chain 152 is fixed, the second support shaft 134 connected to the other end of the lifting chain 152 is lifted upward. This lifting height may be equal to or slightly higher than the height of the container 107.

  As the second support shaft 134 is lifted, the holding members 112 and 112 attached to the lower portions of the bosses 136 and 136 attached to the lower portion of the second support shaft 134 also move upward. The first support shaft 128, the sprocket 130, the second support shaft 134, the third support shaft 142, the lifting chain 152, the cylinder 154, and the like constitute a vertical movement mechanism for the holding members 112, 112 of the lift device 106.

  A cylinder switch 155 for extending and shortening the cylinder 154 of the lift device 106 and a motor switch 145 for driving and stopping the forward / reverse motor 144 are provided. When these switches are operated, the cylinder 154 and the forward / reverse motor 144 are driven. By providing the control device 158 to be operated, the operation of stacking the containers 107 in a multi-stage is facilitated.

FIG. 14 shows a simplified side view of the vicinity of the storage table 104 when stoppers are provided before and after the holding member 112 of the lift device 106.
In addition, a stopper 105 having an interval of about one container (the size of the container used for the root vegetable harvesting machine is almost the same nationwide) is provided at the lower part of the storage base 104 in front of the cradle 100. A conveying roller 110 and a holding member (lowered state) 112 of the lift device 106 that lifts the container 107 may be provided between the front and rear of the stopper 105. The stopper 105 can prevent the container 107 on the transport roller 110 from moving back and forth.

  Note that the container 107 and the stopper 105 may interfere with each other when the container 107 is sent out due to the presence of the stopper 105. However, by making the upper surface of the stopper 105 and the upper surface of the transport roller 110 substantially the same height, It doesn't matter.

FIG. 15 shows a simplified side view of the vicinity of the storage base 104 when the shape of the holding member 112 of the lift device 106 is changed.
Further, as shown in FIG. 15, of the holding members 112, 112 before and after the lift device 106, the holding member 112 in the front (conveyance lower side) close to the container transfer device 114 has the claw portion 112 a on the inner side (container side). It is good also as a shape which inclines and protrudes upwards from the upper surface of the conveyance roller 110. FIG. Since the holding member 112 on the conveyance end portion side protrudes above the upper surface of the conveyance roller 110, the container 107 on the storage platform 104 does not advance to the container transfer device 114 and is set on the lift device 106.

  Further, a claw part sensor 160 that detects the presence or absence of the container 107 may be provided on the claw part 112a of the front holding member 112 near the container transfer device 114 among the holding members 112, 112 before and after the lift device 106. When the claw sensor 160 detects that the container 107 is held by the holding members 112, 112, the cylinder 154 of the lift device 106 is automatically extended to raise the container 107 without operating the cylinder switch 155. Thus, control is possible by the control device 158, and workability is improved.

  Then, the container 107 that has been lifted by the lift device 106 is kept held by the front and rear holding members 112 and 112 at that position until the container is sent from the cradle 100 to the lower side.

  The stoppers 105 may be provided as a pair of front and rear, but may be provided only in the vicinity of the holding member 112 on the lower conveyance side (front). When the container 107 is sent from the cradle 100, the operator pushes the container 107 forward vigorously, so the container 107 is difficult to return to the upper transport side (rear). Therefore, the container 107 sent from the cradle 100 can be fixed between the front and rear holding members 112 and 112 simply by providing the stopper 105 in the vicinity of the holding member 112 on the lower conveyance side.

  The stopper 105 may be provided with a stopper sensor 161 that detects the presence or absence of the container 107. When the stopper sensor 161 senses that the container 107 has been sent onto the storage table 104 (the container 107 is on the storage table 104), the lift is automatically performed without operating the cylinder switch 155 or the motor switch 145. The control device is configured so that the cylinder 107 of the apparatus 106 is contracted to lower the container 107 and the forward / reverse rotation motor 144 is driven so that the front and rear holding members 112, 112 are spread outward and the container 107 held on the lower container 107 is overlapped. Control by 158 becomes possible. Therefore, workability is improved.

  After the containers 107 are stacked in this way, the cylinder 154 of the lift device 106 is expanded again, and the front and rear holding members 112 and 112 are further lifted to rise above the upper surface of the upper container 107.

  When the front and rear holding members 112, 112 are in the uppermost position (the upper end position of the second bearing groove 133 on which the second bearing 132 of the second support shaft 134 can slide), the stacked containers 107 are moved to the front container transfer device. 114 is sent manually.

  When the container 107 is sent from the storage table 104 to the container transfer device 114 and the stopper sensor 161 detects that the container 107 is not on the storage table 104, the front and rear holding members 112, 112 are lowered to store the storage table. The drive of the cylinder 154 and the forward / reverse motor 144 is controlled by the control device 158 so as to return to the original position on 104. Then, the front and rear holding members 112, 112 return to the original state supported between the stoppers 105.

In FIG. 16, the side view of the accommodating part G vicinity at the time of providing an auxiliary mounting base is shown.
An auxiliary mounting table 162 may be provided on the sorter side (rear) sitting on the auxiliary work seat 95 of the cradle 100. By providing the sending rotary body (sending roller) 164 on the auxiliary mounting table 162, the container 107 can be smoothly sent to the receiving table 100 if the sorter pulls the container 107 forward with the right hand.

By placing the empty container 107 on the auxiliary mounting table 162, the empty container 107 is immediately placed on the receiving table 104 when necessary, for example, when the container 107 on the receiving table 100 is full. Since it can be placed, it is excellent in workability.
Further, when a one-way clutch (not shown) that rotates only in one direction (front side) is provided on the delivery roller 102 of the cradle 100 and the feed roller 164 of the auxiliary mounting table 162, The container 107 is less likely to swing and is stable.

  Further, when the working surfaces of these delivery rollers 102 and 164 that come into contact with the container 107 are covered with an elastic body such as rubber, the resistance with the container 107 is increased, and the container 107 is more difficult to swing and stabilizes. In addition, since the container 107 without the contents is very light, the container 107 is easily affected by vibrations, inclinations, strong winds, and the like of the airframe, and there is a possibility that the container 107 falls outside the airframe if resistance is not applied to some extent. Although the resistance when the container 107 is fed out is certainly increased by using an elastic body such as rubber, it does not cause a problem because it does not require such a large force.

  When the height of the cradle 100 is made slightly higher than the heights of the auxiliary mounting table 162 and the storage table 104 on both sides, the container 107 on the auxiliary mounting table 162 does not move toward the cradle 100, and the auxiliary mounting table 162 is fixed. Since the empty container 107 is placed on the auxiliary placing table 162, the weight is light and the sorter can easily send the container 107 to the receiving table 100 even if there is a slight difference in level. On the other hand, since the container 107 containing ginseng is heavy, when sending it to the storage platform 104 on the lower transport side, it is more burdensome for the sorter to send it from the higher height receiving platform 100 to the lower storage platform 104. Becomes lighter.

  The containers 107 and 107 stacked on the storage table 104 by the lift device 106 are sent to the container transfer device 114 adjacent to the storage table 104 and transferred to the front side of the machine body by the container transfer device 114.

FIG. 17 shows a detailed view of the container transfer device 114. FIG. 17A shows a partial plan view, and FIG. 17B shows a partial front view.
The container transfer device 114 includes a pair of left and right frames 168 and 168 having a longitudinal direction in the front and rear, a pair of left and right driven rotators (driven sprockets) 165 provided at the transfer start end portion between the left and right frames 168 and 168, A pair of left and right drive rotating bodies (drive sprockets) 166 provided at the transfer end portion, a pair of left and right transfer chains 167 and 167 wound between the left and right driven sprockets 165 and the left and right drive sprockets 166, and the container 107 A one-way clutch (not shown) that rotates only in the transfer direction, and is arranged between the pair of left and right transfer chains 167, 167 in parallel in the transfer direction of the container 107, and below the upper transfer chains 167, 167 And a transfer roller (transfer rotator) 170 that rotates in contact with the container 107 to transfer the container 107. That.

The transfer roller 170 is supported by a transfer roller support shaft 170b fixed to the left and right frames 168 and 168, and the lower portions of the upper transfer chains 167 and 167 are in contact with the upper portions of the groove portions (small diameter portions) 170a at both the left and right ends. ing.
The left and right drive sprockets 166 and 166 are driven by the motor 171, and the transfer roller 170 rotates in the transfer direction (front side) of the container 107 by the rotation of the transfer chains 167 and 167 and the driven sprockets 165 and 165. Therefore, the container 107 can be reliably transferred even in the case of multi-stage stacking in which the weight of the transferred article increases, and the work efficiency is improved.

18A and 18B are perspective views of an air mat 175 placed on the container 107. FIG. FIG. 19 is a rear view showing the relationship among the sorting and conveying conveyor 92, the air mat 175, and the container 107.
The carrots conveyed from the sorting and conveying conveyor 92 fall into the container 107 on the cradle 100 and are accommodated. In order to prevent carrots from being damaged by the impact of dropping at this time, an air mat 175 may be provided as a shooter to be handed over from the sorting and conveying conveyor 92 to the container 107 at the lower end of the sorting and conveying conveyor 92. There is a bottom frame (not shown) below the sorting and conveying conveyor 92 and before and after the second conveying frames 84 and 84, and the base of the air mat 175 is fixed thereto.

The air mat 175 can be easily prepared by sending air into the interior by a compressor 176 (FIG. 9) or the like and inflating it. Due to the cushioning property of the air mat 175, it is possible to absorb the impact at the time of dropping and prevent the carrot from being cracked.
In addition, the air mat 175 is in a state where it is shrunk and wound in a spiral shape when there is no air inside (it may be wound and attached with a ridge), but it expands and swells when air is introduced. Then, it can be expanded and contracted according to the amount of carrot entering the container 107, and the carrot fall position can be changed.

  For example, the air mat 175 can be formed in a bellows shape, and can be made of a material that expands when air enters. Therefore, it is only necessary to attach a curl to a highly variable material or to form a highly variable material in a bellows shape.

  For example, as shown in FIG. 19 (a), when there is no carrot in the container 107, the air mat 175 is filled with air to expand, and the carrot is far from the sorting and conveying conveyor 92 of the container 107. To reach the end of the. Then, as shown in FIG. 19 (b), when the carrot enters the container 107, the dropping position is changed so that the carrot shrinks gradually, and the container 107 is dropped to the end near the sorting and conveying conveyor 92. By doing in this way, the ginseng enters the container 107 evenly. Therefore, the space in the container 107 can be used effectively.

Further, when the air mat 175 is not used, the air mat 175 shrinks and rounds, so it is compact and does not take up space. Since the air mat 175 is rounded downward, it does not hinder carrots falling from the sorting and conveying conveyor 92.
Further, detection means such as a cradle sensor 177 for detecting the presence / absence of the container 107 is provided on the cradle 100, and when the empty container 107 is placed, the compressor 176 is controlled by the control device 158 by a signal from the cradle sensor 177. If the air mat 175 is driven to automatically enter air into the air mat 175, the air mat 175 expands at a stretch, which is convenient. Also, workability is good.

  In addition, a pedal 178 (FIG. 9) for extending / contracting the air mat 175 may be provided at the foot of the sorter sitting on the auxiliary work seat 95, and the compressor 176 may be driven when the pedal 178 is depressed. By allowing the air mat 175 to be extended and contracted with the feet, both hands can be used freely, so that the sorting work is not hindered and the workability is improved.

  In some cases, the carrots are accommodated by stacking the containers 107 in two stages on the cradle 100 without using the lift device 106. Cylinder (not shown) that supports the transport end of the sorting transport conveyor 92 so that the transport end of the sorting transport conveyor 92 (driven sprocket 87 side) rotates upward with the transport start end (drive sprocket 85 side) as a fulcrum. ) And a jack (not shown), and by raising the conveyance end portion of the sorting and conveying conveyor 92 by these rotating devices, carrots can be carried into the upper container 107. The rotating device may be attached to the vicinity of the driven sprocket 87 of the second transport frame 84 (FIG. 4), and further, a sorting transport conveyor sensor 180 for detecting the height position of the sorting transport conveyor 92 is provided at the same position. By providing a potentiometer or the like on the rotating shaft at the boundary between the first transport frame 83 and the second transport frame 84 of the sorting transport conveyor 92, the sorting transport conveyor sensor 180 can be obtained.

  Then, as shown in FIG. 19 (c), when the sorting and conveying conveyor 92 is at the lowermost position (dotted line position) and at the uppermost position (solid line position), the compressor is controlled by the control device 158 by a signal from the sorting and conveying conveyor sensor 180. Even if the air mat 175 is automatically driven into the air mat 175 when the 176 is driven, the air mat 175 extends at a stretch, which is convenient. Also, workability is good.

  Further, as shown in FIGS. 18A and 18B, the air mat 175 can be comb-shaped or lattice-shaped, or provided with long holes, so that mud can be removed from the gaps or holes. Further, as compared with the case where the air mat 175 is not subjected to processing such as a lattice shape, the amount of air put into the air mat 175 can be reduced, and the expansion / contraction time of the air mat 175 can be shortened.
