  In FIG. 1, a state in which the handle structure 90 is turned so as to be positioned above the hood 14 at the front portion of the airframe 10 is shown.

  The handle structure 90 can be freely turned around the handle structure turn shaft 91a in the vertical direction in the direction indicated by the double arrow X3 using the handle structure turn mechanism 91.

  In the case where the work progress direction of the machine body 10 is the direction indicated by the arrow X1, the handle structure 90 is at the rear part of the machine body 10 in order to perform the field management work in which the plowing depth is a normal depth. It is turned so as to be located above the tail wheel 80. That is, it is suitable for work that is used when the load is medium to heavy.

  In the case where the work progress direction of the machine body 10 is the direction indicated by the arrow X2, the handle structure 90 is, for example, a field management work such as an intercostal groove leveling work, a vertical work that raises a ridge, or a heel. Is turned to be positioned above the hood 14 at the front of the machine body 10 for multi-work to cover the soil surface.

  The direction indicated by the arrow X2 is an example of a predetermined direction in the present invention.

  A support frame 13 to which an engine 20 and a transmission case 30 are attached is provided below the hood 14 at the front of the body 10. A pair of left and right axles 12 that support the pair of left and right traveling wheels 11 project from a lower portion of the front portion of the transmission case 30.

  A fuel tank 50 having a fuel tank cap 51 is provided above the engine 20. The rotational power of the engine 20 is transmitted to the transmission case 30 by the belt covered by the belt cover 15. The rotational power decelerated by the transmission case 30 is transmitted to the pair of left and right traveling wheels 11 and the tilling device 40.

  A base part of a handle structure 90 to which the rotary clutch lever 21 and the like are attached is connected above the transmission case 30.

  Next, the configuration and operation of the walking management machine of the present embodiment will be described more specifically with reference mainly to FIGS. 2 (a), 2 (b) and 3. FIG.

  FIG. 2A is a partial sectional view taken along the line BB ′ (see FIG. 2B) in the vicinity of the leveling mechanism 1000 of the walking type management machine according to the embodiment of the present invention, and FIG. FIG. 3 is a partial left side view of the vicinity of the leveling mechanism 1000 of the walking type management machine according to the embodiment of the present invention, and FIG. 3 is a schematic partial perspective view of the vicinity of the leveling mechanism 1000 of the walking type management machine of the embodiment of the present invention. FIG.

  The tillage device 40 is a device that performs tillage using power transmitted from the transmission case 30 provided in the body 10.

  The leveling mechanism 1000 is a mechanism attached to the transmission case 30.

  The tillage device 40 is provided in the transmission case 30 in the present embodiment, but may be provided in the body 10 in the modified embodiment.

  In the embodiment of the modified example, a safety member is attached to the flange 31 of the transmission case 30 for suppressing the dash phenomenon in which the tilling claws 42 do not enter the hard soil and the body 10 jumps out in the work progress direction. May be.

  The leveling mechanism 1000 includes a leveling plate 1100 positioned behind the tillage device 40 when the machine body 10 travels in the direction indicated by the arrow X2.

  The leveling plate 1100 is attached to the lower side of the transmission case 30 so as to be positioned between the tilling shaft 41 of the tilling device 40 and the axle 12 of the traveling wheel 11. Accordingly, the transmission case 30 is a rigid body, and the load resistance from the soil crushed by the tilling device 40 is considerably smaller than the load resistance from the soil that is not crushed, so that the leveling plate 1100 is not easily deformed.

  The leveling mechanism 1000 includes a leveling plate mounting stay 1200 for mounting the leveling plate 1100 to the transmission case 30.

  The leveling plate attaching stay 1200 is attached to the flange 31 on the rear side of the transmission case 30 when the airframe 10 travels in the direction indicated by the arrow X2.

  Since the front side of the leveling plate mounting stay 1200 is attached to the transmission case 30, even if the leveling plate 1100 attached to the rear side of the leveling plate mounting stay 1200 is subjected to load resistance from the soil, the leveling plate mounting stay 1200 The applied force is a tensile force in the direction indicated by the arrow X1. Therefore, since the rigidity of the plate relating to the tensile force is large, deformation of the leveling plate mounting stay 1200 hardly occurs.

  The leveling plate mounting stay 1200 includes a left leveling plate mounting stay portion 1210 and a right leveling plate mounting stay portion 1220.

  The flange 31 is adjacently positioned between the left leveling plate mounting stay 1212 and the right leveling plate mounting stay 1220.

  The upper hole 1211 of the left leveling plate mounting stay 1212 is a long hole through which the screw 1201 passes, and the lower hole 1212 of the left leveling plate mounting stay 1210 is a long hole through which the screw 1202 passes. The upper hole 1221 of the right leveling plate mounting stay 1220 is a long hole through which the screw 1201 passes, and the lower hole 1222 of the right leveling plate mounting stay 1220 is a long hole through which the screw 1202 passes.

  The holes 1211, 1212, 1221 and 1222 are long holes whose longitudinal directions substantially coincide with the vertical direction. Therefore, the mounting position of the leveling plate 1100 in the up-down direction can be adjusted in consideration of the amount of sediment in front of the leveling plate 1100 that is affected by the height from the farm scene.

  In the modified embodiment, the holes of the flange 31 corresponding to the holes 1211, 1212, 1221 and 1222 may be long so that the mounting position of the leveling plate 1100 in the vertical direction can be adjusted.

  The length N in the vertical direction of the leveling plate mounting stay 1200 is half or more of the length M in the vertical direction of the leveling plate 1100.

  Since the length M is sufficiently large, even if the load resistance that the leveling plate 1100 suffers from the soil becomes considerably large, deformation of the leveling plate mounting stay 1200 hardly occurs.

  The residual tillage processing member 2000 is a member attached to the lower center of the leveling plate 1100.

  The soil on the lower side of the center of the leveling plate 1100 that is difficult to be crushed by the tillage device 40 is crushed cleanly by the residual tillage processing member 2000 protruding in the direction indicated by the arrow X2.

  Since the after-plowing treatment member 2000 is attached to the leveling plate 1100, the after-plowing treatment member attaching stay for attaching the after-plowing treatment member 2000 to the transmission case 30 is unnecessary, and an increase in the number of parts is suppressed.

  It is desirable that the after-plowing treatment member 2000 is detachably attached to the leveling plate 1100 so that maintenance by replacing only the worn after-plowing treatment member 2000 can be easily performed.

  The leveling plate 1100 includes a left leveling plate portion 1110, a central leveling plate portion 1130, and a right leveling plate portion 1120 that are arranged in the left-right direction when the airframe 10 travels in the direction indicated by the arrow X2. .

  An outer end 1110 a that is the left end of the left leveling plate portion 1110 and an outer end 1120 a that is the right end of the right leveling plate portion 1120 are located behind the central leveling plate portion 1130.

  Since the leveling plate 1100 forms a V-shaped rigid body in a top view that is not easily deformed, the amount of the soil accumulation in front of the leveling plate 1100 is suppressed, and the leveling plate 1100 is prevented from entering the soil. . Therefore, the load resistance that the leveling plate 1100 suffers from the soil does not become excessively large, and the body 10 can easily proceed.

  The outer ends 1110a and 1120a are bent in an L shape toward the rear. Therefore, since the traveling wheel 11 is difficult to step on the soil pushed to the outside of the machine body 10 by the tilling device 40, the leveling work can be stably performed.

  The height of the upper end of the leveling plate 1100 substantially matches the height of the axle 12 of the traveling wheel 11. Accordingly, since the height of the leveling plate 1100 is not excessively large, the soil crushed by the tilling device 40 is easily pushed out of the leveling plate 1100, and the amount of the sediment in front of the leveling plate 1100 is reduced moderately. The running resistance of the airframe 10 does not increase.

  The right end of the left leveling plate portion 1110 is attached to the left end of the central leveling plate portion 1130 so that the position in the left-right direction can be adjusted.

  The center leveling plate portion 1130 is located adjacent to the front of the left leveling plate portion 1110.

  The upper hole 1111 of the left leveling plate portion 1110 is a long hole through which the screw 1101 passes, and the lower hole 1112 of the left leveling plate portion 1110 is a long hole through which the screw 1102 passes.

  The holes 1111 and 1112 are long holes whose longitudinal direction substantially coincides with the left-right direction. Therefore, the mounting position of the left leveling plate portion 1110 in the left-right direction can be adjusted in consideration of the width of the ridge or the groove between the ribs.

  In the modified embodiment, the hole in the central leveling plate portion 1130 corresponding to the holes 1111 and 1112 may be a long hole so that the mounting position of the left leveling plate portion 1110 in the left-right direction can be adjusted. .

  The left end of the right leveling plate portion 1120 is attached to the right end of the central leveling plate portion 1130 so that the position in the left-right direction can be adjusted.

  The central leveling plate portion 1130 is located adjacent to the front of the right leveling plate portion 1120.

  The upper hole 1121 of the right leveling plate 1120 is a long hole through which the screw 1103 passes, and the lower hole 1122 of the right leveling plate 1120 is a long hole through which the screw 1104 passes.

  The holes 1121 and 1122 are long holes whose longitudinal direction substantially coincides with the left-right direction. Accordingly, the mounting position of the right leveling plate portion 1120 in the left-right direction can be adjusted in consideration of the width of the ridge or the groove between the ribs.

  In the modified embodiment, the hole in the center leveling plate portion 1130 corresponding to the holes 1121 and 1122 may be a long hole so that the mounting position of the right leveling plate portion 1120 in the left-right direction can be adjusted. .

  Since the leveling bottom plate 1300 is firmly attached to the lower end of the central leveling plate portion 1130 so as to connect the left portion of the central leveling plate portion 1130 and the right portion of the central leveling plate portion 1130 using welding or the like. The V-shape of the central leveling plate portion 1130 in the top view is not easily deformed, and the leveling plate 1100 is prevented from entering the soil. Therefore, the load resistance that the leveling plate 1100 suffers from the soil does not become excessively large, and the body 10 can easily proceed.

  As shown in FIGS. 4 (a) and 4 (b), the protruding width δ at the front end of the leveling bottom plate 1300 is the same as the plate thickness of the right leveling plate portion 1120. It almost matches the thickness.

  4A is a partial cross-sectional view of the leveling mechanism 1000 of the walking type management machine according to the embodiment of the present invention (see FIG. 2A), and FIG. It is a typical fragmentary perspective view of the leveling mechanism 1000 of the walk type management machine of embodiment in this invention.

  In FIG.4 (b), the AA 'line cross section of the leveling mechanism 1000 is shown.

  Since the leveling bottom plate 1300 horizontally supports the lower end of the left leveling plate portion 1110 and the lower end of the right leveling plate portion 1120 with the protruding width δ of the front side end, both the left leveling plate portion 1110 and the right leveling plate portion 1120 are in the center. It is difficult to tilt when attached to the leveling plate 1130.

  Since the leveling bottom plate 1300 that receives the soil surface of the trough or the inter-groove groove is formed with an L-shaped rigid body in a cross-sectional view that is difficult to be deformed together with the leveling plate 1100, the leveling plate 1100 is prevented from entering the soil. Therefore, the load resistance that the leveling plate 1100 suffers from the soil does not become excessively large, and the body 10 can easily proceed.

  Next, the configuration and operation of the walking type management machine of the present embodiment will be described more specifically with reference mainly to FIGS. 5 (a), 5 (b) and 6. FIG.

FIG. 6 is a partial perspective view of the vicinity of the tail wheel 80 of the walking management machine according to the embodiment of the present invention.

  Since the height of the resistance rod 70 held by the resistance rod holder 71 can be adjusted by using the tail wheel vertical adjustment mechanism 81, it is attached to the lower end of the resistance rod 70 that receives the soil surface of the trough or intercostal groove. The height of the tail wheel 80 is also adjustable.

  The tail wheel 80 is a twin wheel whose height is easily adjusted by screw rotation of the tail wheel up / down adjustment mechanism 81, and a change in the body posture caused by the movement of the body 10 in the vertical and horizontal directions is caused by the traveling wheels 11. In addition to being suppressed not only by the tail wheel 80, the amount of earth press and the load resistance relating to the leveling plate 1100 are adjusted within a predetermined range. Therefore, since the tilt of the airframe 10 in the left-right direction is suppressed, the work can be easily performed, and the tilt of the leveling plate 1100 in the left-right direction is also suppressed, so that the leveling plate 1100 due to the left-right asymmetry of the load resistance is suppressed. The deformation of is less likely to occur, and the soil surface of the furrow or intercostal ditch after leveling becomes almost horizontal.

  By adjusting the height of the tail wheel 80, it is possible to easily change the cutting depth of the tilling claw 42 into the field scene.

  The tail wheel 80 is a twin wheel in the present embodiment, but may be a single wheel disposed at the center in the left-right direction of the fuselage 10 in the modified embodiment.

  The transmission case 30 may be configured using HST (Hydro Static Transmission) so that the vehicle speed can be adjusted steplessly while traveling in consideration of the amount of earth pressure and load resistance related to the leveling plate 1100. desirable.

  The rotary left and right slide cover 62 is a pair of left and right sheet metal covers, and is slid in the direction indicated by the double arrows X5 and X6.

  The rotary side cover 63 is a pair of left and right sheet metal covers, and is rotated and opened in the direction indicated by the double arrow X7.

  The rotary center cover protector 64 is a single rubber protector, and is positioned on the front side of the rotary center cover 61 in order to suppress the scattering of soil when the aircraft 10 travels in the direction indicated by the arrow X2. Installed on.

  The left and right rotary slide cover protector 65 is a pair of left and right rubber protectors, and is provided on the front side of the rotary left and right slide cover 62 in order to suppress the scattering of soil when the machine body 10 travels in the direction indicated by the arrow X2. Installed to be located.

  The rotary side cover protector 66 is a pair of left and right rubber protectors, and is attached so as to be positioned outside the rotary side cover 63 in order to suppress scattering of soil.

  As shown in FIG. 7, the extension protector 68 may be attached together with the wing member 67.

  FIG. 7 is a partial top view of the vicinity of the tillage device 40 of the walking type management machine according to another embodiment of the present invention.

  The wing members 67 are four rubber members, and are attached between the rotary left / right slide cover 62 and the rotary side cover 63 in order to suppress scattering of soil, and form a slope like a ridge. .

  The extension protector 68 is a pair of left and right rubber protectors, and is positioned outside the rotary center cover protector 64 in order to suppress the scattering of soil when the airframe 10 travels in the direction indicated by the arrow X2. It is attached to and forms a slope like a ridge.

  In the modified embodiment, at least one of the pair of left and right extension protectors 68 may be provided integrally with the rotary center cover protector 64.

  Since the extension protector 68 extends downward from the lower end of the wing member 67, when the aircraft 10 travels in the direction indicated by the arrow X2, the soil scattered from the wing member 67 is extended by the extension protector. It collides with 68 and falls down. Therefore, the load resistance that the leveling plate 1100 suffers from the soil does not become excessively large, and when the aircraft 10 moves in the intercostal grooves, the soil does not scatter to the crops on the both sides of the intercostal grooves.

  The walking type management machine in the present invention can improve the leveling accuracy in the field management work, and is useful for the purpose of being used as a walking type management machine for performing various field management work including tilling work.
