JP 2013-135626 A

  The walking type root vegetable harvesting machine is provided with a pulling device fixed to the front part of the machine body, pulling up the foliage of a crop that has fallen in the field, and then handing it over to the pulling and conveying device while pulling up with the pulling lug of the device. However, there is a case where the pulling lag does not reach the foliage part stuck to the field scene, and in that case, the foliage part cannot be pinched by the drawing / conveying device, resulting in a pulling mistake.

For this reason, it is necessary to adjust the vertical height of the pulling device. However, since the pulling device is integrally attached to the airframe, recombination work is necessary and cannot be performed during the harvesting work.
In the present invention, by facilitating the vertical adjustment of the raising lug of the pulling device, the root vegetable harvesting can be carried out by reliably taking over the stems and leaves of root vegetables with different lying states to the pulling and conveying device. The challenge is to make it a machine.

The problems of the present invention are solved by the following technical means.
According to the first aspect of the present invention, a drawing / conveying device (19) is provided from the front lower portion to the rear upper portion of the body frame (1), and a laterally raised lug (39a) is provided in front of the drawing / conveying device (19). In a root crop harvesting machine provided with a laterally raising device (41) in which the laterally raising belt (39) circulates in a backward inclined posture, the machine body frame (in which the backwardly inclined posture of the laterally raising device (41) can be changed) 1) It is possible to adjust the backward tilting posture of the laterally raising device (41) with a laterally raising device adjusting tool (21) pivotally supported on the aircraft frame (1) provided at the rear control unit. The root crop harvester is the characteristic.

  According to a second aspect of the present invention, the horizontal raising frame (37) of the horizontal raising device (41) is pivoted to the drawing frame (14) of the drawing conveying device (19) via a pivot shaft (24). 2. The frame (37) is supported by a laterally raised frame (37) supported by a wire (26) connected to a tension spring (25) and a laterally raised device adjusting tool (21) provided in the control unit. The root crop harvesting machine described.

  According to a third aspect of the present invention, the laterally raising device adjusting tool (21) is configured by an angle adjusting lever that is provided at a lower portion of the handle (8) of the traveling vehicle body (2) and that rotates in the vertical direction. It is set as the root vegetable harvester of Claim 1 or Claim 2 characterized by the above-mentioned.

  According to a fourth aspect of the present invention, there is provided a scraping plate having a diameter that is equal to or larger than a rotational locus of the laterally raised lug (39a) on the laterally raised drive pulley (36) side of the laterally raised device (41). (85) is provided, It is set as the root vegetables harvester of any one of Claims 1-3 characterized by the above-mentioned.

  The invention according to claim 5 is characterized in that a discharge shooter (86) is provided on the rear side of the scraping plate (85) to guide the foliage that rises laterally and comes off the lug (39a) to the outside of the machine. The root vegetable harvester according to claim 4 is used.

  According to the sixth aspect of the present invention, a drawing / conveying device (19) is provided from the front lower part to the rear upper part of the machine body frame (1), and a laterally raised lug (39a) is provided in front of the drawing / conveying device (19). A laterally raising device (41) around which the laterally raising belt (39) circulates is provided in a backward inclined posture, and a crushing roll (124a, 124b) is provided at the lower end of the drawing and conveying device (19) to reversely rotate. A root vegetable harvesting machine is provided, which is provided with a crushing shooter (127) for finely crushing the foliage falling from the conveying device (19) and guiding the crushed foliage outside the apparatus.

  In the first aspect of the present invention, the operator in the rear control unit of the machine body frame (1) operates the horizontal raising device adjusting tool (21) to change the inclination of the horizontal raising device (41). Since the position where the horizontally raised rug (39a) acts on the foliage can be adjusted up and down, the root vegetables that have fallen down can be reliably pulled out and harvested by the pulling and conveying device (19) while continuing the harvesting operation.

In the invention according to claim 2, in addition to the effect of claim 1, the rearward tilting posture of the device (41) can be changed with the pulling and conveying device (19) as a reference, so that the fouling adjustment of the foliage can be adjusted. It becomes easy.
In the invention of claim 3, in addition to the effect of claim 1 or claim 2, the laterally raising device adjusting tool (21) is provided at the lower part of the handle (8). The operator of the control unit that performs the steering operation on the handle (8) does not cause the horizontal pulling and tilting of the device (41) by accidentally touching the device adjusting tool (21).

  In the invention according to claim 4, in addition to the effect of any one of claims 1 to 3, the laterally raising belt (39) is caused to laterally raise and disengage from the drive pulley (36). While being prevented by the dropping plate (85), the plate (85) has an action of scraping off the foliage that is laterally raised and entangled with the lug (39a).

  In the invention of claim 5, in addition to the effect of any one of claims 1 to 4, the foliage part falling from the lateral pulling device (41) is removed from the machine by the discharge shooter (86). Therefore, a good harvesting operation can be continued without obstructing the harvesting of the root vegetables being pulled out by the pulling and conveying device (19) and being conveyed backward.

  In the invention according to claim 6, since the foliage part conveyed to the terminal part of the drawing and conveying apparatus (19) is finely crushed and discharged to the field by the crushing shooter (127), it interferes with the harvesting work of unharvested crops. Therefore, since the foliage is crushed, it is prevented that the spoiled foliage contaminates the soil and hinders the cultivation of the next crop.

Are arranged in a tilted posture, and the rear end portions of the left and right handle support frames 7, 7 are connected by a handle 8 having a "U" shape in plan view. The handle 8 is disposed so as to protrude rearward from the fuel tank 5, and clutch handles 9 and 9 for turning on and off a side clutch mechanism (not shown) are provided on the left and right sides of the handle 8, respectively.

  Further, as shown in FIG. 2, a travel operation lever 10 for operating the forward and backward movement and travel speed of the aircraft is provided on the left side of the fuel tank 5, that is, on the left side of the aircraft, and used for harvesting work on the right side, that is, on the right side of the aircraft. A work operation lever 11 for switching on / off of driving force to the pulling / conveying device 19, the lateral pulling device 41 and the vertical pulling device 64 described later is provided. An engine stop switch 96 for stopping the engine 2 is provided on the left side of the handle 8, and a throttle lever 97 for increasing or decreasing the rotational speed of the engine 2 is provided on the right side.

  As shown in FIGS. 1 and 2, left and right pulling drive shafts 12, 12 are provided in a downwardly inclined posture toward the front upper side from the branch transmission case 6, and upper ends of the left and right pulling drive shafts 12, 12. The left and right pulling drive pulleys 13 and 13 are mounted on the left and right, respectively. Further, left and right pulling frames 14 and 14 having long sides in the front-rear direction are provided in the lower part of the left and right pulling drive pulleys 13 and 13 respectively in a rearwardly rising posture, and left and right at the front end portions of the left and right pulling frames 14 and 14, respectively. The pulling driven pulleys 15 and 15 are rotatably provided.

  Further, a plurality of left and right pulling driven pulleys 15, 15 are provided rotatably between the left and right pulling driven pulleys 15, 15 and the left and right pulling driving pulleys 13, 13. The left and right pulling drive pulleys 13, 13 and the left and right tension rollers 16, 16,... The left and right extraction covers 18 and 18 are provided above the left and right extraction frames 14 and 14 in a parallel posture with the left and right extraction frames 14 and 14, that is, in a rearward rising inclination posture having substantially the same inclination angle. A transport device 19 is configured.

  Further, the left and right shaft covers 12a and 12a covering the left and right pulling drive shafts 12 and 12 guide the stems and leaves of the onion discharged from the transfer terminal end of the pulling transfer device 19 to the right or left side of the machine body. The defoliation guide plates 20 are arranged respectively. The left and right leaflet guide plates 20 and 20 are disposed below the left and right pulling drive pulleys 13 and 13 and at a position outside the machine body where the pulling and conveying device 19 does not transfer the foliage, that is, a non-working position. In addition, the left and right leaflet guide plates 20 and 20 are made of an elastic material such as a spring steel material.

  With the above-described configuration, when the foliage portion of the onion cut by the cutting rotary blade 49 and the cutting fixed blade, which will be described later, moves to the terminal portion of the drawing and conveying device 19, the foliage portion is connected to the left or right drawing conveyance belt 17 and the drainage leaf. Since it is discharged to the left outer side or right outer side of the machine body while being sandwiched between the guide plates 20, it is prevented that the foliage part remains on the drawing / conveying device 19 and the machine frame 1, and the cut foliage part is removed. Is no longer necessary, and maintenance is improved.

  Note that the leaflet guide plate 20 protrudes outward from the machine body and guides the stems and leaves discharged toward the space between the pulling and conveying device 19 and left and right drive wheels 84L and 84R, which will be described later. This prevents the foliage part from remaining on the airframe and eliminates the need for removing the foliage part.

  Further, as shown in FIGS. 6 to 8, a support plate 99 that is long in the vertical direction is provided on the left and right sides of the rear side of the body frame 1, and the support plate 99 is disposed on the left and right sides from the branch transmission case 6. The left and right ends of the extended output shaft 6a are passed through. A base of a rotating rod 100 for rotating the rocking sourer 29 in the front-rear direction in a plan view is provided on the left side of the support plate 99, that is, on the left outer side of the body, and on the right side of the support plate 99, that is, on the right inner side of the body. A base part of a rocking rod 101 for rocking the rocking soiler 29 in the longitudinal direction of the machine body is provided.

The rocking rod 101 is also provided on the left side of the machine body, and the left rocking sounder 29 is similarly rocked.
The rotating rod 100 includes a rotating eccentric cam 100a into which the output shaft 6a is inserted, and a rotating shaft portion 100b in the front-rear direction attached to the rotating eccentric cam 100a, and a front end portion of the rotating shaft portion 100b. A pillow ball 100c is provided. The swing rod 101 is configured by providing a swing shaft portion 101b between a swing eccentric cam 101a into which the output shaft 6a is inserted and a mounting boss 101c on the front side of the machine body.

  Then, the pillow ball 100 c provided at the front end of the rotating rod 100 is provided on the rotating plate 103 provided on the upper part of the vertical rotating arm 102. The rotating plate 103 is detachably attached to the upper end of the sour rotating arm 102, and when mounted, the rotating plate 103 rotates in conjunction with the rotating rotating plate 103. In addition, a rotation connection pin 103a is provided on one side of the rotation plate 103 on the left and right sides (outside the machine body), and the rotation connection pin 103a is inserted and connected to the pillow ball 100c.

  Thereby, when the rotating rod 100 is rotated by the output shaft 6a, the rotating plate 100 reciprocates in the front-rear direction by the eccentric rotation of the swing eccentric cam 100a, and is connected to the pillow ball 100c by the front-rear reciprocating movement. 103 is reciprocatingly rotated in the front-rear direction in a plan view, and is configured to reciprocally rotate in the front-rear direction in conjunction with the solitary rotation arm 102 provided at the lower portion of the rotation plate 103.

  Further, a bifurcated solitary support arm 105 is provided in the vertical direction below the sour rotating arm 102, and the upper side of the swinging soli 29 is inserted into the bifurcated portion of the sora support arm 105. And connecting holes (not shown) respectively formed in the swinging sour 29, and fixing members 29a such as bolts and nuts are inserted into the connecting holes to fix the swinging sour 29. The oscillating sour 29 has a configuration in which the lower side is bent toward the pulling and conveying area and formed into an L shape (reverse L shape) when viewed from the front, and enters the soil from the side of the ridge.

  A plurality of the connection holes are formed in the vertical direction on either or both of the support arm 105 and the swing soiler 29, and the working height of the swing soiler 29 is changed by changing the combined connection hole. If possible, it can be set to an appropriate height that meets conditions such as the vertical length of the crop to be harvested, the depth of burial in the soil, or the presence or absence of multi-film, and the soil to be harvested is not damaged. Therefore, the quality of root vegetables is maintained and the work efficiency is improved.

  In addition, a protective cover (not shown) is provided at least at the connecting portion between the pillow ball 100c and the rotating connecting pin 103a to stop the rotating operation by biting a foliage portion or sand into the connecting portion, or the biting sand, etc. This prevents the pillow ball 100c and the rotation connecting pin 103a from being worn away.

  A hollow solitary swinging case 107 is provided on the outer periphery of the sour rotating arm 102 and between the rotating plate 103 and the upper and lower support arms 105. A swing connecting pin 106 for inserting the mounting boss 101c of the swing rod 101 is provided on the upper end side of the inner side of the body of the rocker swing case 107.

  Even when the solitary rocking case 107 is moved in the front-rear direction by the rocking rod 101, the solitary rotating arm 102 is interlocked with the rotation of the rotating plate 103 by the rotating rod 100. It is set as the structure which can reciprocately rotate to a direction.

  Thus, when the swinging rod 101 is rotated by the output shaft 6a, the swinging eccentric cam 101a is reciprocated in the front-rear direction by the eccentric rotation of the swinging eccentric cam 101a, thereby reciprocatingly swinging the solitary rotating arm 102 in the front-rear direction. .

  With the above configuration, when the output shaft 6a rotates, the rotating rod 100 is reciprocated in the front-rear direction, and along with this reciprocating movement, the soli-rotating arm 102 reciprocally rotates in the front-rear direction in plan view. Since the swinging sour 29 provided on the arm 105 can be rotated in the front-rear direction in a plan view, the soil can be dug reliably from the base side to the end side of the swinging sour 29. The soil is prevented from resisting when the onion is pulled out, and the work efficiency is improved.

  In particular, since the soil around the onion planted at a position away from the mounting base of the swinging soiler 29 in the body inner direction, that is, the onion planted near the center in the left-right direction of the kite, can be easily unwound. The efficiency is improved, the onion is prevented from being left unchecked, and the time and labor for the operator to manually harvest the onion are reduced.

  In addition, since the swinging sour 29 rotates about the left and right side of the swinging arm 102 as a fulcrum, the amount of rotation increases toward the other left and right sides of the swinging soy 29, so that the width before and after unraveling the soil becomes wider. The soil is dug more reliably and the efficiency of the onion pulling and harvesting work is improved.

  Further, when the output shaft 6a rotates, the rocking rod 101 is reciprocated in the front-rear direction, so that the rocking soiler 29 can be swung in the front-rear direction. As a result, the onion is prevented from being pulled out and damaged, and the operator does not need to dig up the onion, thereby reducing the labor of the operator.

  Furthermore, the rocking rod 101 is swung in the front-rear direction by the rocking rod 101 and the rocking sour 29 is swung in the front-rear direction by the rotating rod 100, so that Since the soil can be unraveled reliably, it is possible to harvest multiple onions without losing pulling out, improving work efficiency and eliminating the need for the operator to manually harvest the remaining onions, Save time and effort.

Next, the structure which cuts the foliage part of the onion extracted from the agricultural field at the determined height and moves it to the agricultural scene will be described.
As shown in FIG. 1 or 2, the upper ends of the left and right rotary shafts 16a and 16a of the left and right pulling driven pulleys 16 and 16 provided at the front end of the pulling and conveying apparatus 19 are connected to the left and right pulling covers 19 and 19, respectively. The left and right transmission cases 34, 34 having left and right input sprockets 31, 31 installed in the front part of the fuselage at the upper end of the left and right rotating shafts 16a, 16a are pulled out left and right in a tilted posture.

Left and right laterally raised belts 39, 39 are wound around the left and right laterally raised belts 39, 39, and left and right laterally raised frames 37, 37 are parallel to the left and right laterally raised frames 37, 37. By providing the cover 40, 40, a lateral pulling device 41 is configured.

  The laterally raised lugs 39, 39 a... Provided on the left and right laterally raised belts 39, 39 are arranged at positions where their tip portions are close to the drawing conveyance area of the drawing conveyance device 19 and are not in contact with each other.

  With the above configuration, the lugs 39a, 39a,... Are prevented from coming into contact with each other, so that the stems and leaves caused by the impact of the contact are prevented from falling, and the onion is surely placed on the field by the pulling and conveying device 19. The work efficiency is improved.

  As shown in FIG. 9, the support frame 22 of the laterally raised frames 37, 37 is supported by the support arm 23 provided on the pulling frame 14 of the pulling / conveying device 19 by the pivot shaft 24, and the tension spring 25 and the wire 26 are used. When balanced and held in a rear-upward inclined posture, the rear end of the wire 26 is connected to the angle adjusting lever 21 provided at the lower part of the handle 8 via two pulleys 27a and 27b. The worker who is performing the operation can operate the angle adjusting lever 21 in a timely manner to raise the lag 39a to the ground height of the foliage portion and maintain the good foliage portion.

  Further, as shown in FIGS. 10 and 11, a scraping plate 85 and a discharge shooter 86 are provided on the rear side of the horizontally raised drive pulley 36 that is horizontally raised and pivotally supported on the upper end of the frame 37. The scraping plate 85 has an outer diameter that is laterally raised and larger than the leading end locus of the lug 39a, prevents the belt 39 from being laterally raised and detached from the drive pulley 36, and is caused by the laterally raised tangled lag 39a. As the lug 39a is turned sideways, it is sent to the tip by the scraping plate 85 as the lug 39a rotates, and the removed foliage slides on the discharge shooter 86 inclined to the side and is released to the side of the aircraft. Is done. The scraping plate 85 may be circular, but if the left and right sides are swelled in an oval shape, the stems and leaves are better detached.

Although not shown, the laterally raised frames 37 and 37 are provided with a belt cover which is laterally raised and covers the belts 39 and 39, and the inclination angle is changed together with the laterally raised frames 37 and 37.
Upper ends of the relay transmission cases 42 and 42 that house the left and right second universal joints (not shown) are provided on the lower side of the left and right output transmission cases 34 and 34, and the lower ends of the left and right relay transmission cases 42 and 42 are provided. Left and right shoulder alignment drive pulleys 43, 43 are provided at the respective portions. The left and right shoulder alignment pulleys 43, 43 are provided with front end portions of left and right upper shoulder alignment frames 44, 44 and left and right lower shoulder alignment frames 45, 45 at the upper and lower portions of the left and right shoulder alignment pulleys 43, 43, respectively. 44 and left and right lower shoulder alignment frames 45, 45, left and right shoulder-aligned driven pulleys 46L and 46R are rotatably attached to the left and right shoulder-aligned drive pulleys 43 and 43 and left and right shoulder-aligned followers, respectively. The left and right shoulder alignment belts 50, 50 are wound around the pulleys 46L, 46R in an endless manner.

  Further, of the left and right upper shoulder alignment frames 44, 44, the upper shoulder alignment frame 44 on one side of the left and right sides of the machine body is provided with a cutting frame 47 that rotates up and down around the rear side of the machine body. A cutting motor 48 that detachably provides a foliage cutting blade 49 that is nipped and conveyed by the left and right shoulder alignment belts 50 and 50 and the left and right pulling conveying belts 17 and 17 and that drives the foliage cutting blade 49 to rotate. Thus, the shoulder aligner 51 is configured to restrict the rise of the onion being transported by the pulling and transporting device 19 by the lower shoulder alignment frames 45 and 45, and to cut the foliage portion after aligning the cutting position to a predetermined position. The

  The cutting motor 48 is easily configured as appropriate from an electric type that operates by receiving electricity from a battery, a hydraulic type that operates by receiving hydraulic oil from a hydraulic valve 92, which will be described later, or another type of operation.

  With the above configuration, the foliage portion is cut by the foliage cutting blade 49 after the cutting position is aligned to a predetermined position, so that the foliage portion is largely left uncut and the operator manually cuts the foliage portion later. Since it becomes unnecessary, the labor of the operator is reduced and the work efficiency is improved.

Further, since the onion is lifted too much and the foliage cutting blade 49 can be prevented from cutting the spherical portion of the onion, the so-called edible portion, the onion is not damaged and the commercial value of the onion is maintained.
And by providing the stalk-and-leaves cutting blade 49 in a detachable manner, when the onion drying operation performed after harvesting is performed by hanging the onion, the stalk and leaf portion can be dug up without being cut, so It will be a highly adaptable crop harvester.

  Further, by providing the cutting frame 47 so as to be pivotable up and down, the cutting frame 47 can be pivoted in the vertical direction so that the cutting height of the foliage cutting blade 49 can be freely changed. When drying in the sun, the cutting height leaves a little (about 3 to 5 cm) of the unstemmed leaves. When hanging the onion on a dryer, etc., the leaves and leaves for hanging the onion are greatly reduced (about 10-20 cm), the cutting height can be left, so that a root vegetable harvesting machine with high adaptability to working conditions can be obtained.

  A fixed cutting blade is detachably provided on the upper shoulder alignment frame 44 on the left and right sides of the machine body, and the fixed cutting blade is overlapped with the upper side or the lower side of the edge of the foliage cutting blade 49 so as to sandwich the foliage portion. Since it can cut | disconnect without letting a foliage part escape, it will remain without cutting a foliage part on an onion, and the operation | work which an operator cuts a remaining leaf manually will become unnecessary. However, when cutting off the leaves and leaves of the onion, the edible part having the commercial value is damaged if it is cut from the vicinity of the spherical part, and the quality and the commercial value are reduced. Shall.

  Further, as shown in FIG. 2, the right shoulder-aligned driven pulley 46R is disposed at the front side of the machine relative to the left shoulder-aligned driven pulley 46L, and the left and right upper shoulder-aligned frames 44, 44 are moved to the left shoulder-aligned driven pulley. Guide bars 52 for guiding the foliage are provided on the pulley 46L side. Furthermore, the left shoulder-aligned driven pulley 46L is provided with a so-called star wheel having a protrusion, and the protrusions and leaves are guided to the left outer side of the machine body by this protrusion.

  With the above configuration, after the cut foliage portion is released from the nipping state at the conveyance end portion of the shoulder aligner 51, the foliage portion is guided to the left side of the machine body by the left shoulder alignment belt 50 and the left and right guide bars 52, 52. Therefore, the discharge direction of the foliage part becomes constant, and the work at the time of collecting the foliage part from the field becomes easy.

  Also, since the foliage is concentrated and discharged on the left side of the machine, it can be prevented that the foliage falls on the unharvested onion on the right side of the machine. This prevents the harvesting operation from being disturbed and improves the work efficiency.

  As shown in FIGS. 1 and 4, on the rear side of the left and right center of the shoulder aligner 51, a guide drive case 56 provided with a guide drive pulley 53 that rotates by receiving a driving force from the branch transmission case 6 is lowered downward. In a tilted position, the rear side is provided so as to be rotatable up and down, and a guide driven pulley 54 is provided rotatably at the lower rear side of the guide drive case 56, and a guide belt 55 is provided on the guide drive pulley 53 and the guide driven pulley 54. The guide device 57 is formed by winding.

  The guide belt 55 constituting the guide device 57 is provided with protrusions at equal intervals on the outer peripheral edge, receives the uncut leaves and leaves, guides the onion onto the cocoon, and the leaves and root (beard) of the onion. The root) is guided to discharge onto the ridge in a posture that does not contact the farm scene.

  As shown in FIG. 4, the guide drive pulley 53 is supported by a drive rotary shaft 53a that rotates by receiving a driving force from the branch transmission case 6 via the bevel gear mechanism 6b, and the guide driven pulley 54 is provided on the right side. It is supported by a driven rotary shaft 54a provided on a pair of left and right support rods 54L and 54R supported from the upper shoulder alignment frame 44.

  At this time, as shown in FIG. 4, the left support rod 54L does not enter the winding region of the guide belt 55 but is bent downward along the guide device 57, and the right support rod 54R is guided to the guide belt. It enters into the winding area of 55 from the left side of the body, and is bent along the guide device 57 from the right side of the body.

  As described above, the guide device 57 can be inclined toward the left side of the aircraft as it goes down the aircraft, so that the root of the onion is guided to the field scene in a posture that does not contact the ground, and the root is again in the dry state. It is prevented from being settled, the onion recovery efficiency is improved, and excessive onion growth is prevented, improving the quality of the harvest.

  In addition, since the rear side of the guide device 57 is configured to be pivotable in the vertical direction, when the guide device 57 is unnecessary, such as when harvesting onion grown on the ground without laying a multi-film, the guide action portion is placed on the body frame 1 side. Therefore, the crop harvester can be adapted to various working conditions.

  As described above, since the lower side of the guide device 57 may come into contact with the multi-film, the guide belt 55 may be composed of a sponge or the like having a lower frictional force than rubber in view of preventing damage to the multi-film. desirable.

  The onion discharged by the guide device 57 falls onto the vegetation that has been vegetated before harvesting, and is collected after harvesting or after drying in the sun. However, since a normal onion is spherical, when it is discharged, the traveling device of a working machine such as a tractor that rolls on the cage and collects the left and right drive wheels 84L and 84R, the gauge wheel 73, and the onion is recovered. May fall into a passing groove. In addition, when a 3 or 4 onion is planted in one persimmon, when the 1st or 2nd onion is harvested, the discharged onion is the unharvested side, that is, the 3rd or 4th onion. May move to the vegetation side.

  In order to solve the above problem, as shown in FIGS. 1 and 4, support stays 130 are provided on the lower side of the body frame 1 and on the left and right sides of the left and right shoulder alignment belts 50 and 50, respectively. The left and right support stays 130 and 130 are each provided with an adjustment support plate 131 having a bent portion inclined downward toward the center of the conveying path of the shoulder aligner 51.

  Then, in the front lower portions of the left and right first guide plates 134 and second guide plates 135, a first notch part 134c and a second notch part 135c that are inclined forwardly downward from the front side of the machine body to the rear side are formed in a side view. The front end portion of the second guide plate 135 forming the second notch portion 135c is formed on the rear side of the machine body from the front end portion of the first guide plate 134 forming the first notch portion 134c. If it is formed at a position about 100 to 150 mm, which corresponds to one onion, at the rear side position of the machine body, the second guide plate 135 does not prevent the onion from moving to the drawing and conveying area of the drawing and conveying device 19, and the onion is surely Pull-out harvesting is possible, improving work efficiency.

  With the above configuration, the first guide plate 134 and the second guide plate 135 have a wider left-right distance in the front (rear) view, so that the two onions are located in the left-right direction at the narrowest left-right distance. When passing side by side, the gap is clogged and it is no longer moved to the rear of the machine body, so there is no need to interrupt the work and eliminate the clogging, and work efficiency is improved.

The left-right distance between the lower ends of the first guide plate 134 and the second guide plate 135 is preferably about 200 to 300 mm, which corresponds to two standard size onions.
Further, if the first guide plate 134 and the second guide plate 135 are each made of a material such as rubber that can be elastically deformed when a strong force is applied, the first guide plate 134 and the second guide plate 135 are less likely to be damaged and last longer.

Then, the left traveling transmission case 80L is in a rear-upward inclined posture, and a traveling driven sprocket 81 is rotatably mounted on the lower end side of the left traveling transmission case 80R located on the front side of the aircraft, and the traveling drive sprocket 79 and the traveling driven are provided. The travel transmission chain 82 is wound around the sprocket 81.

  A tension sprocket may be provided in the winding region of the travel transmission chain 82, or a clutch mechanism may be provided to stop the drive and prevent breakage by retracting from the travel transmission chain 82 when a load is applied.

Further, an axle 83 is mounted on the traveling driven sprocket 81, and a left drive wheel 84L is attached to the axle 83.
1 to 4, a left output shaft 78L is slidable in the left-right direction at the left end of the branch transmission case 6, and a travel drive sprocket 79 is attached to the left output shaft 78L. The traveling drive sprocket 79 is provided in the upper part of the left traveling transmission case 80L. At this time, the mounting hole portion of the traveling transmission case 80L for mounting the left output shaft 78L is slightly larger than the diameter of the right output shaft 78R, and the left output shaft 78L slightly moves up and down and front and rear. A configuration that can be used.

  Further, the left traveling transmission case 80L is disposed in a rearwardly inclined posture, and a traveling driven sprocket 81 is rotatably mounted on the lower end side of the left traveling transmission case 80L located on the front side of the aircraft, and the traveling driving sprocket 79 and the traveling driven are provided. The travel transmission chain 82 is wound around the sprocket 81. Further, an axle 83 is mounted on the travel driven sprocket 81, and a left drive wheel 84L is provided on the axle 83.

  Further, the left traveling transmission case 80L is moved in the left-right direction between the branch transmission case 6 and the left traveling transmission case 80L in front of the left output shaft 78L and between the branch transmission case 6 and the left traveling transmission case 80L. An adjustment cylinder 89 that adjusts the left-right distance, that is, a so-called tread, is provided so as to be extendable in the left-right direction. A sliding guide 90 that slides in the left-right direction together with the left output shaft 78L by the expansion and contraction of the adjusting cylinder 89 is provided in the body frame 1 in front of the adjusting cylinder 89. Further, the sliding guide 90 and the left output shaft 78L are connected by a connecting plate 91, and the adjustment cylinder 89 is extended and retracted in a U-shaped groove portion 91u formed in the connecting plate 91. Thereby, the tread adjusting mechanism 95 is configured.

  2 and 3, the base of the adjustment cylinder 89 on the fixed side, that is, the left side of the machine body is attached by a rotation pin 89a, and the end of the adjustment cylinder 89, that is, the right side of the machine body is in the vertical direction. It is set as the structure which can be freely rotated.

  A hydraulic valve 92 that supplies hydraulic oil for expanding and contracting the adjustment cylinder 89 is disposed above the mission case 3 and closer to the center in the left-right direction of the machine body. The hydraulic valve 92 is provided with a relief valve 92r so that when a high load is applied to the hydraulic circuit, the hydraulic oil is released from the relief valve 92r to the oil tank 92t to prevent damage due to overload. At this time, as shown in FIG. 5, the oil feeding hose 93 that exchanges hydraulic oil from the hydraulic valve 92 to the adjusting cylinder 89 is also configured to pass through the groove 91u.

  The adjustment cylinder 89 is an electric type, and a bimetal switch that deforms due to a temperature rise due to the load is provided between the electric adjustment cylinder 89 and a power source (battery). It is good also as a structure which expansion-contraction of stops.

  Further, a tread adjustment lever 94 for extending and retracting the adjustment cylinder 89 is provided on the hydraulic valve 92 so as to be rotatable in the left-right direction. The tread adjusting lever 94 has a “h” shape that is bent rearward and upward. The grip portion at the end is located near the worker standing behind the fuselage.

  As shown in FIGS. 1 to 3, an air cleaner 2p through which the engine 2 sucks outside air is located below the tread adjusting lever 94 and is largely from a muffler (not shown) that discharges the exhaust of the engine 2. The arrangement configuration is to be separated.

  In the above configuration, the adjustment cylinder 89 is expanded and contracted to change the left / right distance between the left and right drive wheels 84L, 84R, so-called tread, so that the tread adjustment mechanism 95 is operated regardless of the traveling speed and forward / reverse travel. Since the tread adjustment can be performed, it is not necessary to interrupt the pulling and harvesting work every time the ridge width changes, and to move the machine forward and backward, thereby improving the work efficiency and reducing the labor of the operator.

  In addition, since the tread can be changed according to the width of the cocoon, the right drive wheel 84R does not move on the ridge when working in a field with a different ridge width, and the onion pulling and harvesting work in a stable posture. Work efficiency can be improved.

  And when loading the fuselage onto a loading platform such as a light truck, or when storing it in a warehouse, the left and right widths of the fuselage can be shortened by narrowing the tread to the limit. Work can be done efficiently.

  Furthermore, by providing the left transmission shaft 78L behind the adjustment cylinder 89 and providing the sliding guide 90 in front of the adjustment cylinder 89, it is possible to disperse the load caused by the grounding or running of the right drive wheel 84R. Therefore, it is possible to prevent the adjustment cylinder 89 from being distorted or twisted and being damaged, the expansion / contraction range is reduced, and the tread adjustment width is limited.

  In addition, when the right traveling transmission case 80R is moved in the left-right direction, the right traveling transmission case 80R is changed in posture because it is configured to push a plurality of locations outward or to pull inside the aircraft. The right driving wheel 84R is prevented from being slightly displaced and the traveling direction of the machine body is disturbed, and the traveling performance and crop harvesting efficiency are prevented from being lowered.

  Further, by setting the diameter of the mounting hole portion of the left traveling transmission case 80L to be slightly larger than the diameter of the right transmission shaft 78R, when the right drive wheel 84R moves up and down due to unevenness in the field, the left transmission Since the shaft 78L can move in the vertical direction and the front-rear direction, the left transmission shaft 78L is prevented from being damaged by the load.

  Further, by providing the fixing base mounting base of the adjustment cylinder 89 via the rotation pin 89a, the adjustment cylinder 89 can be moved to the left drive wheel even if the left drive wheel 84L moves up and down due to unevenness of the field. Since it moves up and down following the vertical movement of 84R, the adjustment cylinder 89 can be expanded and contracted when adjustment of the tread is required, and there is no need to change the vertical position of the left drive wheel 84L, thereby improving work efficiency. .

  Further, since the left output shaft 78 and the sliding guide 90 are connected by the connecting plate 91, the left output shaft 78 and the sliding guide 90 slide in conjunction with each other, so that the right traveling transmission case 80R and the drive wheel 84L are connected. An inclined posture is prevented, an arbitrary tread can be set, and running performance is stabilized.

  Further, since the hydraulic valve 92 is provided with a relief valve 92r that moves the hydraulic oil to the oil tank 92t to reduce the pressure, even if the tread adjusting lever 94 is erroneously operated while the traveling is stopped, When the pressure in the hydraulic valve 92 increases, the relief valve 92r returns the hydraulic oil to the oil tank 92t, and the expansion and contraction of the adjustment cylinder 89 can be stopped, so that the tread adjustment mechanism 95 is prevented from being damaged due to overload. The

  If the right drive wheel 84R is slid to the side of the fuselage while traveling is stopped, a strong grounding resistance is generated, so that the adjustment cylinder 89 and the left output shaft 78L are overloaded, and the tread adjustment mechanism 95 is activated due to an erroneous operation or the like. Although there is a problem that it is damaged if it is not noticed, in this configuration, the expansion and contraction of the adjustment cylinder 89 automatically stops before an overload is applied, so that the occurrence of the problem is prevented.

  When the adjustment cylinder 89 is extended to the maximum or contracted to the minimum, the tread adjustment lever 94 continues to be operated, and when an overload occurs, the hydraulic oil returns from the relief valve 92r to the oil tank 92t. Therefore, the expansion / contraction operation of the adjustment cylinder 89 is automatically terminated, and the tread adjustment mechanism 95 is prevented from being damaged.

  Further, since the adjusting cylinder 89 and the oil feeding hose 93 in which the hydraulic oil moves are arranged in the groove portion 91u of the connecting plate 91, the oil feeding hose 93 can be removed simply by removing it from the adjusting cylinder 89. At times, the number of members to be attached and detached is reduced, and the maintainability is improved.

  Since the tread adjustment lever 94 has a shape that bends rearward and upward, it is easier for the operator who performs the maneuvering operation behind the fuselage to operate the tread adjustment lever 94, thereby reducing the labor of the operator. In addition, the operability is improved.

  Furthermore, by arranging the tread adjusting lever 94 at a position above the air cleaner 2p and away from the muffler in the left-right direction, the operator is not exposed to the high-temperature exhaust gas discharged from the muffler. Work comfort is improved.
