Since the alignment chain 48 and the alignment guide body 52 move, it can be prevented from being bitten by the alignment device 54 even if the diameter of the onion foliage is large, and the jammed foliage is removed by stopping the machine. There is no need to improve work efficiency.

  In addition, if the tension of the tension plates 53 and 53 is set to be weaker than the tension of the urging springs 50 and 50, the alignment chains 48 and 48 will be in an appropriate position when the large-diameter foliage passes and a load is applied. Therefore, it is possible to prevent the position alignment device 54 from being bitten, and it is not necessary to stop the machine body and remove the bitten foliage, thereby improving work efficiency.

Then, elongated holes are formed in the transmission cases 37, 37 in the vicinity of the alignment drive sprockets 42, 42 and outside the alignment guide bodies 52, 52, and the surfaces of the alignment guide bodies 52, 52 are formed in the elongated holes. The left and right scrapers 55 and 55 for removing pieces and mud of the foliage adhering to the head are attached along the locus of the alignment guide bodies 52 and 52 at the time of position adjustment.

The left and right guide rails 212 and 212 are set to have the same rearward and upward inclination posture as that of the pulling and conveying device 24, and the inclination angle is also set to be the same.

  In addition, the left and right auxiliary driven sprockets 210 and 210 and the left and right auxiliary drive sprockets 203 and 203 are wound around the left and right auxiliary alignment chains 211 and 211, respectively, so that the cutting positions of the onion stems and leaves are aligned. An auxiliary alignment device 213 is configured. The left and right auxiliary alignment chains 211 and 211 have a plurality of chain covers 51, 51... As in the left and right alignment chains 48 and 48 constituting the alignment device 54. As a result, it is possible to prevent the onion from falling downward during the conveyance of the pulling and conveying device 24.

  In the above configuration, when the vertical position of the auxiliary position aligning device 213 is changed, the front end side moves back and forth, and the position of the rear end does not change. For example, it is connected to the left and right second output shafts 41 and 41. The left and right auxiliary input shafts 201 and 201 are bendable rotary shafts such as universal joints, the auxiliary drive sprockets 203 and 203 are configured to be movable rearward, and the auxiliary driven sprockets 210 and 210 are configured not to move in the front-rear direction. It can also be considered.

  With the above configuration, when the left and right auxiliary input shafts 201 and 201 are moved up and down by rotating the left and right couplings 202 and 202, the left and right guide rails that are attached to the left and right transmission cases 37 and 37, respectively. The left and right slide pins 211 and 211 inserted into the notch grooves 212a and 212a of the 212 and 212 are raised or lowered by the guide rails 212 and 212, whereby the left and right slide frames 208 and 208 move back and forth to move the left and right springs. 206 and 206 can be expanded and contracted.

  Specifically, when the couplings 202 and 202 are turned upward, the slide pins 211 and 211 are lifted upward as the guide rails 212 and 212 are lifted, whereby the slide frames 208 and 208 are pulled backward. By contracting the springs 206, 206, the auxiliary position aligning device 213 can be contracted to the front and back length substantially the same as the position aligning device 54. On the other hand, when the couplings 202 and 202 are turned downward, the slide pins 211 and 211 are pushed downward as the guide rails 212 and 212 are lowered, thereby pushing the slide frames 208 and 208 forward and springs 206 and 212. By extending 206, the auxiliary position aligning device 213 can be extended so that the longitudinal length of the auxiliary aligning device 213 is longer than the longitudinal length of the aligning device 54.

  The left and right cutting blade rotation shafts 56 and 56 are attached to the rear position of the alignment device 54 of the left and right first gear units 38 and 38, and the left and right bearings 57 and 57 are attached to the cutting blade rotation shafts 56 and 56, respectively. Mount freely. Then, left and right support plates 59, 59 are attached to the left and right bearings 57, 57, and left and right foliage cutting blades 60, 60 are attached to the support plates 59, 59 to constitute a foliage cutting device 61.

  Further, left and right foliage conveyance drive pulleys 62 and 62 are attached to the left and right first output shafts 40 and 40, and the left and right foliage conveyance drive pulleys 62 and 62 are attached to the front side of the machine body above the left and right first gear units 38 and 38 and above the alignment devices 54L and 54R. The foliage driven pulleys 63 and 63 are rotatably attached. Then, by winding the left and right defoliation conveyor belts 64 and 64 endlessly around the left and right foliage conveyance driving pulleys 62 and 62 and the left and right foliage conveyance driven pulleys 63 and 63, Is disposed below the left and right transmission cases 37 and 37 and below the end of conveyance of the pulling and conveying device 24.

  Further, left and right remaining leaf conveyance drive pulleys 66 and 66 are pivotally attached to the upper ends of the left and right first output shafts 40 and 40, and the left and right remaining leaf conveyance driven pulleys 67 and 67 are rotatable above the transmission cases 37 and 37. A plurality of left and right remaining leaf conveyance tension pulleys 68, 68 are attached between the left and right remaining leaf conveyance driving pulleys 66, 66 and the left and right remaining leaf conveyance driven pulleys 67, 67. Then, left and right residual leaf conveyance belts 69, 69 are wound endlessly around the left and right residual leaf conveyance driving pulleys 66, 66, left and right residual leaf conveyance driven pulleys 67, 67, and left and right residual leaf conveyance tension pulleys 68, 68. Thus, the remaining leaf conveyance device 70 that sandwiches the upper part of the foliage and conveys it to the rear of the machine body is configured above the defoliation conveyance device 65.

  A foliage shooter 71 for discharging the foliage cut by the foliage cutting device 61 from the end portions of the above-mentioned foliage conveyance device 65 and the remaining leaf conveyance device 70 to the field is provided to constitute the foliage cutting portion D.

  With the above configuration, the left and right alignment drive sprockets 42 and 42 are arranged at positions separated from the left and right spacing portions of the alignment device 54 through which the foliage passes, so that the alignment drive sprockets 42 and 42 and the second output are output. Since it is possible to prevent the stems and leaves from being entangled with the shafts 41 and 41 and stop the alignment device 54, the harvesting operation is not interrupted and the work efficiency is improved.

  Further, since the alignment drive sprockets 42 and 42 have a smaller diameter than the alignment driven sprockets 45 and 45 and the alignment tension sprockets 47 and 47, the alignment drive sprockets 42 and 42 are further spaced apart from each other by the left and right spacing portions of the alignment device 54. Therefore, it is possible to further prevent the stems and leaves from being entangled with the alignment drive sprockets 42 and 42 and the second output shafts 41 and 41, and the work efficiency is further improved.

  Further, by providing the left and right biasing springs 50 and 50 for biasing the alignment driven sprockets 45 and 45, the slack that occurs in the left and right alignment chains 48 and 48 when the foliage comes into contact with the alignment device 54. Since the alignment chains 48 and 48 immediately return to the tension state, the alignment device 54 can reliably receive the foliage of the onion even when the foliage of different diameters pass continuously. In addition, the cutting positions of the onions and stems of the onion are properly aligned and the stems and leaves are appropriately cut, and there is no need to remove the stems and leaves in a subsequent process, thereby improving work efficiency.

  Further, by adjusting the tension of the biasing springs 50, 50 by moving the left and right receiving plates 49, 49 in the front-rear direction, the growth situation of the onion, the difference in the diameter of the foliage depending on the variety, the weather and the soil Since the tension can be appropriately changed according to the working conditions of the working place, etc., cutting the harvesting part when cutting the foliage part is prevented, and the commercial value of the crop is improved.

  It is best to cut the onion at a position where a certain amount of foliage remains in the harvesting part. This is because if the boundary between the harvesting part and the foliage part is cut, the inside of the onion is exposed, the inside is excessively dried, and the quality is deteriorated.

  Further, the left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the machine body, and the rotation shafts 46, 46 having the alignment driven sprockets 45, 45 attached to the holes 44, 44 are movable. In the state where no load is applied, the alignment driven sprockets 45, 45 urged by the urging springs 50, 50 move toward the conveyance path of the foliage, so that the small foliage passes through. Therefore, the position aligning device 54 can receive the foliage portion to properly align the cutting position of the onion foliage portion, eliminating the need to remove the foliage portion remaining on the onion in a later step, and improving the work efficiency.

  Further, when a large load is applied to the alignment device 54 when the large diameter foliage portion passes, the alignment driven sprockets 45, 45 move along the holes 44, 44 away from the movement path of the foliage portion. Therefore, the left and right intervals on the front side of the alignment device 54 are widened, the foliage portion can be prevented from being bitten into the gap portion of the alignment device 54, and there is no need to stop the body and remove the bitten foliage portion. , Work efficiency is improved.

  If it is known before harvesting that the stems and leaves of the onion have a large diameter, the alignment driven sprockets 45 and 45 are moved away from the left and right of the alignment device 54 to align the alignment. If the left-right distance on the upper side in the conveying direction of the device 54 is increased, the alignment device 54 can be prevented from biting the foliage part, and there is no need to remove the bited foliage part, thereby improving the work efficiency.

  When the right and left tension plates 53L and 53R are provided in the winding region of the alignment chains 48 and 48, the alignment chains 48 and 48 are pressed from within the winding region. Since the alignment chains 48 and 48 of the portion where the tension plates 53 and 53 are not pressed can be retracted in the direction of the alignment drive sprockets 42 and 42, the foliage may be caught between the left and right of the alignment device 54. In addition, it is not necessary to remove the foliage that has been bitten by stopping the airframe, improving the work efficiency.

  Further, by providing left and right scrapers 55 and 55 for scrubbing debris and dirt such as mud adhering to the alignment guide bodies 52 and 52 moving on the outer periphery of the alignment drive sprockets 42 and 42, Since the foreign substances adhering to the alignment guide bodies 52, 52 can be removed at a position away from the moving path of the parts, the foliage fragments are prevented from getting entangled with each part of the alignment device 54, and the machine body is stopped. This eliminates the need to remove the tangled stalks and leaves, improving the work efficiency and preventing the mud from damaging the root of the onion, thereby improving the commercial value of the onion.

  Furthermore, since the installation positions of the scrapers 55 and 55 can be changed along the long holes, the scrapers 55 and 55 are set at optimum positions in accordance with the average diameter of the stems and leaves of the onion where the harvesting operation is performed. The above-described effect is further improved by reliably removing the debris of the foliage and dirt such as mud from the alignment guide bodies 52 and 52.

  And when the left and right couplings 202, 202 are rotated, the vertical height and the longitudinal length of the auxiliary alignment device 213 can be changed, so that the foliage part is long in the vertical direction like an onion, and the harvesting part (bulb part) When harvesting short crops, the auxiliary alignment device 213 is lowered to make the front and back length longer, and when harvesting crops with a small difference in length between the stem and leaf parts of the carrots and the harvesting part (root part) Since the auxiliary position aligning device 213 can be raised to shorten the front-rear length, different crops can be harvested and versatility is improved.

  In addition, since the vertical position can be adjusted according to the variety and size of onion and carrots to be harvested, the cutting position of the foliage part is appropriate, preventing damage to the harvesting part, and improving the product value of onions and carrots To do.

  Further, the left and right guide rails 212 and 212 are rearwardly inclined at the same inclination angle as that of the pulling / conveying device 24, so that even if the vertical height of the auxiliary position aligning device 213 is changed, the position alignment with the auxiliary position aligning device 213 is performed. Since the positional relationship of the device 54 can be maintained in parallel, the alignment position of onions and carrots is not disturbed, and the cutting position of the foliage is stabilized.

  In addition, as shown in FIG.1 and FIG.10, when harvesting carrots or when it is necessary to leave a foliage part longer on the onion, the auxiliary alignment device 213 is raised to a position just below the alignment device 54 to increase the longitudinal length. When the length is shortened, a pair of left and right foliage guides 35 and 35 for guiding onion and carrot foliage from the pulling and conveying device 24 to the position aligning device 54 and the auxiliary position aligning device 213 are inserted into the left and right pulling frames 15 and 15. Attach to each.

  As described above, the foliage is guided by the left and right foliage guides 35 and 35 until the foliage is transferred from the pulling and conveying device 24 to the alignment device 54 and the auxiliary alignment device 213, so that the foliage is aligned. In addition, since the onion and carrot can be prevented from falling without entering the conveyance area of the auxiliary position aligning device 213, the onion and carrot are prevented from being damaged by the impact of the drop, and the commercial value is improved. In addition, it is not necessary to manually cut the foliage part in which the foliage part remains in the carrot, and the work efficiency is improved and the labor of the operator is reduced.

  The transfer preparation device described below cuts the leaves and leaves that remain in the onion, but if the leaves and leaves are too long, the leaves and leaves fall down during the transfer and cannot be cut at an appropriate position. Since a problem may occur that the foliage is clogged and the conveyance is stagnated, it is necessary to cut the foliage before the operator moves it. During this time, the movement and sorting of the onion are interrupted, and the work efficiency is reduced. Therefore, it is desirable that the onion is moved to the temporary storage part E after the foliage part is cut over a predetermined length by the foliage cutting device 61.

  Then, the leaf discharge shooter 71 that discharges the leaves (cut stems and leaves) cut from the onion by the stem and leaf cutting device 61 to the field so that the leaves and leaves are discharged to the already dug side (the side on which the onion has been harvested).

Is determined to have started, the transport drive motor 120 is automatically operated, and the collection container conveyer 121 moves the container 106 to the front side of the machine body.

  When the storage container 106 moves to the front side of the machine body and the recovery container sensor 122 is in a non-detection state across the entire front and rear, it is determined that the next storage container 106 can be set in the storage work unit 113, and the transport drive motor 120 is automatically stopped and the collection container conveyor 121 is stopped.

At this time, when the worker moves the empty collection member 106 from the extended mounting table 112 and covers the upper part of the storage work unit 113 with the storage container 106, the recovery container sensor 122 is again in the detection state across the entire front-rear direction. .
If the empty storage container 106 is not set in the storage work section 113, the front and rear root cutting drive motors 84 are turned on even if the rotation preparation shooter 107b of the crop discharge shooter 107 is rotated downward and the transfer preparation on / off switch 110 is turned on. , 84 and the front and rear leaf cutting drive motors 95, 95 are configured not to operate.
Thereby, the accommodating part G is comprised.

As described above, since the storage work unit 113 for setting the storage container 106 is provided below the crop discharge shooter 107, there is no need to separately form an onion discharge path, and the configuration is simple and the number of parts is reduced. Is done.
Since the collection container conveyor 121 is provided, the storage container 106 that has become heavier with the onion stored therein can be automatically conveyed to the front side of the machine body, so that the distance for the operator to move the storage container 106 is shortened. The labor of the worker is reduced and the labor of the worker is reduced.

  Further, a pair of left and right transport belts 118, 118, 118, 118 is formed as a set, and a plurality of auxiliary transport rollers 119, 119... Are provided between the left and right transport belts 118, 118, 118, 118 in the front-rear direction. This arrangement prevents the conveyor belts 118, 118, 118, 118 from being bent due to weight during transportation of the heavy-duty container 106, thereby stopping the transportation, so that the operator can move the container 106. There is no need to make it work and work efficiency is improved.

  Further, by rotating the storage container mounting table 111 and moving it to the working unit frame 20 side, the left and right widths of the machine body can be shortened by the width of the storage unit G when not working. The space required for loading in the loading platform and storing in the warehouse can be reduced.

  Then, by providing the extended mounting portion 112 for loading the empty storage container 106 at the rear end of the storage container mounting table 111, the empty storage container 106 can be set in the storage operation unit 113 simply by moving it forward. Work efficiency is improved.

  In addition to the above, the extension mounting part 112 is prevented from protruding to the rear side of the machine, the front and rear width of the onion harvesting machine when not working is suppressed, and the onion harvesting machine is loaded into the truck bed and stored in the warehouse The space required for doing so is further reduced.

  Further, when the extension mounting portion 112 is rotated backward from the machine body, if it is configured to stop at a position where it is slightly raised and inclined from the bottom surface of the storage container mounting table 111, it will slide down from the extension mounting portion 112 to the front side of the machine body. Since the front part of the empty storage container 106 is pressed by the rear part of the storage container 106 that is collecting the onion by the storage work part 113, the storage container 106 is moved from the storage work part 113 to the front side of the machine body. Thus, the empty storage container 106 is automatically moved to the storage operation unit 113, and the operation of setting the empty storage container 106 in the storage operation unit 113 is facilitated, and the work efficiency is improved.

  Further, a collection container sensor 122 that detects the presence or absence of the storage container 106 is provided in the storage work unit 113, and when the rear side of the recovery container sensor 122 is in a non-detection state, the transport drive motor 120 automatically operates and Since the conveyance drive motor 120 automatically stops when the storage container 106 no longer detects the container 106 over the entire area, it is not necessary to drive the collection container conveyor 121 at all times, and power consumption and fuel consumption can be suppressed. , Energy saving effect is improved.

  If the collection container sensor 122 does not detect the storage container 106 over the entire area, the root cutting drive motors 84 and 84 and the front and rear driving motors 84 and 84 are moved forward and backward even if the rotation shooter 107b is rotated downward and the conveyance preparation on / off switch 110 is turned off. Since the leaf cutting drive motors 95 and 95 are configured not to operate, it is possible to prevent the onion from being discharged from the transport preparation device 104 in a state where the storage container 106 is not set in the storage work unit 113. This eliminates the need for the work of collecting the balls, improves the work efficiency, prevents the onion from being damaged when dropped, and maintains the commercial value of the onion.

Hereinafter, another embodiment of the present onion harvester will be described.
As shown in FIGS. 17 and 18, an input pulley 171 is attached to the upper end portion of the rotating shaft of the driven pulley 16 on the inner side (the other side on the left and right sides) of the machine body, and a scraping cover 172 is placed obliquely forward on the upper portion of the input pulley 171. It is made to project. Then, an output pulley 173 having a diameter smaller than that of the input pulley 171 is rotatably mounted on the front end portion of the scraping cover 172, and the scraping belt 174 is wound around the output pulley 173 and the input pulley 171 to assist A scraping device 176 is configured.
The scraping belt 174 is provided with a scraping lug 174a made of an elastic body such as rubber at a predetermined interval, and a plurality of the scraping lugs 174a. Guide to the beginning.

  A through hole is formed in the input pulley 171, and a drive pin 175 is inserted through the through hole. When the drive pin 175 contacts the driven pulley 16 on the inner side of the machine body, the input is interlocked with the rotation of the driven pulley 16. The pulley 171 is configured to rotate. When the drive pin 175 is removed from the input pulley 171 or moved to a position where it does not contact the driven pulley 16, the driven pulley 16 rotates, but the input pulley 171 does not rotate.

  The drive pin 175 has a structure in which the input pulley 171 rotates in conjunction with a spring or the like once pushed in, and the input pulley 171 does not rotate when pushed in again, or a female screw groove is formed in the through hole and driven. When a male screw groove is formed on the surface of the pin 175 and the input pulley 171 rotates interlocked when tightened and stops rotating when loosened, the interlocking rotation is released without completely removing the drive pin 175 from the input pulley 171. Therefore, it is possible to prevent the drive pin 175 from being lost.

  Then, the weed rod 157 is disposed at the lower end of the rotating shaft of the driven pulley 16 inside the machine body so as to protrude to the front side of the machine body. The weed rod 157 is formed with a hole into which a fixing member 177 such as a bolt can be inserted into the mounting base, and when the fixing member 177 is inserted into the hole, the fixing rod 157 is in a fixed state. It is set as the structure which can be rotated and can adjust a weeding angle.

  When the input pulley 171 is rotated in conjunction with the driven pulley 16 and the fixing member 177 is removed and the weed rod 157 is rotated, the input pulley 171 rotates in conjunction with the auxiliary scraper 176. It is good also as a structure which moves. With this configuration, the auxiliary scraping device 176 can be stored in the lower part of the pulling / conveying device 24 and within the left and right widths when not in operation, and therefore, the auxiliary scraping device 176 is prevented from continuously contacting and distorting the storage location. Therefore, the scraping performance is maintained.

  Furthermore, a scraping disk 178 provided with a plurality of protrusions on the outer periphery around a plurality of protruding claws or a disc is provided at the lower end of the rotation shaft of the output pulley 173, and the lower surface of the scraping disk 178, That is, the side close to the farm is formed in a spherical shape. If the spherical surface or the entire scraping disk 178 is made of a synthetic resin having a characteristic that it is difficult to be damaged even when a frictional force is applied, the durability is improved and the effect is prolonged.

  With the above configuration, the stems and leaves that are not caused by the vertical pulling device 25 and the horizontal pulling device 26 but are suspended on the ground surface can be scraped by the auxiliary scraping device 176 and guided to the pulling and conveying device 24. Since the onion can be pulled out while sandwiching the stem and leaf portion of the potato, the amount of onion left behind is reduced and the work efficiency is improved.

In addition, the auxiliary scraping device 176 is provided on the driven pulley 16 on the inner side of the fuselage where the already dug side where the onion has already been harvested is located, so that only the stem and leaf portion of the onion currently being drawn and harvested is scraped. Therefore, the stems and leaves of the uncollected onion are drawn out from the field, and the onion is prevented from being pulled out by the drawing / conveying device 24 during the next operation, thereby preventing the onion from being left behind.
Then, by obtaining the driving force of the auxiliary scratching device 176 from the driven pulley 16 of the pulling and conveying device 24, there is no need to form another transmission path, the machine structure is simplified, and the number of parts is reduced.

  Furthermore, since it is possible to switch whether the input pulley 171 rotates in conjunction with the driven pulley 16 by attaching and detaching the drive pin 175, such as when the onion stalks are growing in summer, etc. Since the auxiliary stirrer 176 may not be used under working conditions that may involve a part, the working conditions that can be handled increase and the working efficiency improves.

Further, by providing the scraping disk 178 at the lower part of the driven pulley 16, it is possible to lift up the foliage portion that is hiding on the ground surface, so that the foliage portion is more reliably pulled out, and it is necessary to carry out the remaining onion. And work efficiency is improved.
Since the lower surface of the scraping disc 178 is formed into a spherical shape, the scraping disc 178 is configured to slide along the field scene, so that the extraction work height of the extraction conveying device 24 may be changed. In addition, the accuracy of the drawing work is improved.

  In addition, when the weed rod 157 is rotated, the working angle of the auxiliary scoring device 176 can be changed by configuring the scraping cover 172 so that it can rotate in conjunction with it. Since the angle can be adjusted and the scraping work can be performed, the efficiency of the scraping work on the foliage is improved.

  As shown in FIG. 19, the left and right strip number adjustment frames 151, 151 are formed into a bowl shape, and a front lock portion 181 is formed on the front side and the inner side of the strip number adjustment frame 151. A rear lock portion 182 is formed on the rear side. Then, a holding slide frame 183 having a length substantially the same as the length of the front lock portion 181 to the front lock portion 182 is provided on the left and right pull-out frames 15 and 15 so as to be slidable in the front-rear direction. A plurality of pressing tension rollers 184 that press the pulling and conveying belts 18 and 18 are rotatably disposed on 183 and 183. Further, the left and right sandwiching slide frames 183 and 183 are notched with stopper grooves 183a that are caught by the rear lock portions 182 and 182 when being slid rearward.

  Further, operation grips 185 for allowing the operator to slide the holding slide frames 183 and 183 back and forth are provided at the rear portions of the left and right holding slide frames 183 and 183, respectively, and the rear end portions of the holding slide frames 183 and 183 and the pull-out frame 15 are provided. , 15 are provided with tension springs 187 for pulling the holding slide frames 183, 183 to the rear side of the machine body between the fixing plates 186, 186, respectively, thereby constituting the strip number changing mechanisms 188, 188.

  When the sandwiching slide frame 183 is positioned between the front lock portion 181 and the rear lock portion 182 and locked, the strip number changing mechanism 188 is substantially parallel to the drawing conveyance path R. In addition to the posture, the plurality of pressing tension rollers 184... Press the position near the front end of the pulling and conveying belt 18, so that the left and right pulling and conveying belts 18 and 18 are in close contact with each other to form a single digging form.

  On the other hand, when the operation grip 185 is grasped and the rear lock portion 182 is pulled to the rear side with a force with which the strip number adjusting frame 151 can get over, the left and right strip number adjusting frames 151 and 151 are separated toward the conveyance start end side and left and right Since the plurality of pressing tension rollers 184 press the left and right drawing / conveying belts 18 and 18 at a position where the drawing and conveying belts 18 and 18 start to come into close contact with each other, a left and right interval portion is formed in the vicinity of the conveyance start end portion, and two strips are formed. The stem and leaf part of the onion can be guided and becomes a two-row digging form.

  In the operation of the holding slide frame 183, the operator needs to operate with at least a force capable of getting over the rear lock portion 182. However, since the tension spring 187 biases the holding slide frame 183 rearward, It is possible to operate with light power. Thereby, the labor of the operator is reduced. However, when the left and right vibration soliters 34 and 34 dig up the unevenness of the field and the soil around the onion, when the vibration occurs in the airframe, the holding slide frame 183 is moved to the rear lock portion. There is a risk that the number of mines will suddenly change after 182. In order to prevent this, lock handles 189 and 189 are provided to switch between a locked state that restricts the rotation of the number adjustment frames 151 and 151 and an unlocked state that releases the rotation restriction of the number adjustment frames 151 and 151. If the lock handles 189 and 189 are not released, the strip adjustment frames 151 and 151 do not rotate, and the sandwiching slide frames 183 and 183 cannot move backward.

  With the above-described configuration, the holding slide frames 183 and 183 are moved back and forth to change the single digging and the double digging, so that the pulling conveying belts 18 and 18 are pushed by the pressing tension rollers 184 provided on the holding slide frames 183 and 183. Since the number of digging strips can be changed by pressing the number of pressing tension rollers 184..., The cost can be reduced.

  Further, since the stopper slide 183a that is hooked to the rear lock portion 182 is formed in the sandwich slide frame 183, the sandwich slide frame 183 is operated until the stopper groove 183a is hooked to the rear lock portion 182. Since it becomes the position, the stems and leaves for the two strips can be reliably pulled out by the drawing / conveying device 24, and the stems and leaves are prevented from clogging the drawing / conveying start end, thereby improving the work efficiency.

(Preferred configuration example)
Hereinafter, a preferred configuration example of the crop harvester for onion harvesting will be described. In addition, below, detailed description is abbreviate | omitted by attaching | subjecting the code | symbol of the said same member.
As shown in FIGS. 20 and 21, the crop harvesting machine 301 is temporarily stored between the pulling / conveying device 24 and the receiving member mounting table 111 to receive a crop from the terminal end of the pulling / conveying device 24.
