JP 2006-081514 A

By the way, in this tea leaf picking machine, in order to transfer tea leaves from the container device to the loading platform of the truck, it is conceivable to open, for example, the bottom surface of the raised container device downward by a drive mechanism that opens and closes the container device. In this case, however, the open bottom surface hangs down from the container device. In order to prevent the drooping bottom surface from coming into contact with the tea leaves of the truck bed, the lifting device must lift the container device by an amount corresponding to the height of the drooping bottom surface, for example. The burden on the lifting device increases.
In addition to this, for example, as disclosed in Patent Document 1, it is conceivable that the back surface of the container device is opened downward and the entire container device is tilted backward by a driving mechanism. In this case, the container device is largely rotated backward in a state where the container device is lifted high. The burden of the drive mechanism that defeats the container device is large. The structure of the drive mechanism is also complicated. In addition, since the center of gravity of the container device also moves rearward by being largely tilted rearward, it is necessary to give the lifting device rigidity or the like so that the container device can be supported at the moved center of gravity. The burden on the lifting device and the drive mechanism is increased.

  Thus, in the tea leaf plucking machine, it is required that the tea leaves accommodated in the container device can be suitably loaded onto the truck bed while suppressing an increase in the burden on the lifting device or the drive mechanism. Yes.

The tea leaf plucking machine of the present invention includes a lifting device that is attached to a traveling machine body that can travel across a teacup so as to be lifted and a container device that is attached to the lifting device and accommodates tea leaves. Has a stationary housing member fixed to the lifting device and a movable housing member that can be opened and closed with respect to the stationary housing member from the rear side, and the movable housing member is closed with respect to the stationary housing member to A container main body that forms an accommodating space that can be accommodated; and an opening / closing mechanism that drives the movable casing member to open the container main body, the container main body being substantially defined by the fixed casing member and the movable casing member. The fixed housing member has at least a front surface portion which is at least a lower portion of the front surface on the lifting device side of the container body having a substantially cubic shape. The movable casing member has at least a bottom surface portion which is a bottom surface of the substantially cubic shaped container main body and a rear surface portion which is at least a lower portion of the rear surface of the container main body, and is rotated so that the whole is lifted rearward and upward. The container device is in a state in which the container body is closed, and a right scattering prevention plate that overlaps a right surface portion that is at least a part of the right surface of the container body, and at least a part of the left surface of the container body. A left scattering prevention plate that overlaps the left surface portion, and the opening / closing mechanism is driven to rotate or slide backward to lift the movable casing member closed with respect to the fixed casing member rearward and upward. , opening the bottom surface portion of the container body rearward and upward.

Preferably, the right scattering prevention plate and the left scattering prevention plate are provided along the vertical direction on both the left and right sides of the front surface portion of the fixed housing member and protrude rearward .

  Preferably, the elevating device lifts the front surface portion to the lower side of the container body and the front surface portion inclines toward the rear lower direction, the movable casing member includes the bottom surface portion, and the Along with the rear surface portion, the container body has an upper surface portion that is at least a part of the upper surface of the container body, and the opening / closing mechanism is configured such that the front surface portion is inclined toward the rear lower direction on the lower side of the container body. In this state, the entire movable casing member may be rotationally driven and lifted along the direction toward the rear upper side.

  Preferably, it has a transport device that transports tea leaves cut from teacups to the container main body by blowing air, and the front portion is formed with a smooth surface at least in the lower part, and the container main body having a substantially cubic shape is It is preferable that the ventilation structure is formed in a portion other than the front portion.

  Preferably, the elevating device connects the traveling machine body and the stationary housing member below the upper arm, and connects the traveling body and the stationary housing member below the upper arm. It is good to have a lower arm longer than an arm, and to raise the container main body by rotating the upper arm and the lower arm in the rear upper direction.

The container device according to the present invention is a container device that is attached to an elevating device that moves up and down in a tea leaf picking machine and that contains tea leaves, and is provided so as to be openable and closable with respect to the stationary housing member on the lifting device side and the stationary housing member. A container body that forms a housing space capable of accommodating tea leaves by closing the movable housing member with respect to the stationary housing member, and driving the movable housing member to open the container body The container body has a substantially cubic shape formed by the fixed housing member and the movable housing member, and the fixed housing member is at least ascending and descending with respect to the container body having a substantially cubic shape. A front surface portion that is at least a lower portion of the front surface on the apparatus side, and the movable housing member is at least substantially in the container body having a substantially cubic shape. The container main body has a bottom surface portion serving as a bottom surface and a rear surface portion serving as at least a lower portion of the rear surface of the container main body, and is rotatable so as to be lifted rearward and upward, with the container main body closed. A right scattering prevention plate that overlaps at least a part of the right surface of the container and a left scattering prevention plate that overlaps at least a part of the left surface of the container body with the container body closed. and, wherein the opening and closing mechanism is driven to rotate the movable skeleton member is closed with respect to the fixed skeleton member to lift obliquely upward, opening the bottom surface portion of the container body obliquely upward.

In this invention, the container main body of a container apparatus has the fixed housing member fixed to a raising / lowering apparatus, and the movable housing member which can be opened and closed from a rear side with respect to a fixed housing member. The movable casing member has at least a bottom portion of the container body, and the opening / closing mechanism is driven to rotate so as to lift the movable casing member closed with respect to the fixed casing member rearward and upward or slide backward. And open the bottom of the container body rearward and upward. Therefore, the bottom of the opened container body is less likely to hang down below the container body.
On the other hand, if the bottom of the container body is opened downward, for example, the bottom of the opened container body hangs down from the container body. In this case, in order not to hit the tea leaves of the truck bed, the lifting device needs to lift the container body by an amount corresponding to the bottom of the container body hanging from the container body. In the present invention, this can be suppressed.

In the present invention, the opening / closing mechanism does not drive the entire container body but drives the movable casing member therein. Moreover, the movable casing member is lifted rearward and upward. Or it is made to slide backward.
On the other hand, for example, when the entire container body is tilted backward, the size and weight of the driven portion increase, and the load on the lifting device and the opening / closing mechanism increases. It is necessary to give the lifting device and the opening / closing mechanism high rigidity or to use a complicated opening / closing mechanism. In the present invention, this can be suppressed. For example, since the opening / closing mechanism only rotationally drives the movable casing member, the opening / closing mechanism can have a simple structure. Compared to the case where the entire container body is moved backward, the number of parts can be significantly reduced. Moreover, since the opening / closing mechanism has a simple structure, play in the opening / closing mechanism is reduced in the container body in the closed state, and the movable casing member is less likely to wobble in the closed container body.

As described above, in the present invention, the tea leaves accommodated in the container main body of the container device can be suitably transferred to the truck bed while suppressing an increase in the burden on the lifting device and the opening / closing mechanism.
And in this invention, the part used as the bottom part of a container main body is provided in the movable housing member, and the bottom part of a container main body can be opened. Therefore, the tea leaves accommodated in the container main body can be efficiently transferred to the loading platform of the truck from the bottom of the opened container main body due to natural fall. Even when the tea leaves are reloaded due to a natural fall, the tea leaves hardly remain in the container body of the container device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an external view of a tea leaf plucking machine 1 according to an embodiment of the present invention. FIG. 1A is a front view. FIG. 1B is a right side view. FIG. 1B shows a loading platform 92 of a truck 91 on the rear side of the tea leaf picking machine 1.
1 includes a traveling machine body 10, a right crawler traveling apparatus 31, a left crawler traveling apparatus 32, a cutting blade apparatus 41, a conveying apparatus 51, a container apparatus 61 that accommodates tea leaves, and a traveling apparatus body. 10 and an elevating device 81 attached to the elevating device. In FIG. 1, the container device 61 is in a lowered position where the tea leaves of the teacup are picked and accommodated. Hereinafter, front, back, left, right, up and down are used on the basis of the state of the tea leaf picking machine 1 of FIG.

The traveling machine body 10 includes a front portal frame 11, a rear portal frame 15, and a base frame 19.
The front portal frame 11 is connected to the right front column portion 12 erected on the right crawler traveling device 31, the left front column portion 13 erected on the left crawler traveling device 32, and the right front column portion 12 and the left front column portion 13. A front beam portion 14 is provided.
The rear gate type frame 15 includes a right rear column portion 16 standing on the rear side of the right front column portion 12 in the right crawler traveling device 31 and a left rear portion standing on the rear side of the left front column portion 13 in the left crawler traveling device 32. It has the pillar part 17, the rear beam part 18 which connects between the right rear pillar part 16 and the left rear pillar part 17. FIG.
The left and right widths of the front portal frame 11 and the rear portal frame 15 can be varied.
The base frame 19 includes, for example, a right front / rear frame 20 and a left front / rear frame 21 that connect the front beam portion 14 and the rear beam portion 18 back and forth. The front beam portion 14, the right front / rear frame 20, the rear beam portion 18, and the left front / rear frame 21 form a substantially rectangular frame as viewed from above. A seat 25 on which an occupant is seated, a handle 26, a lever 27, a driving device 28, a hydraulic device (not shown), and the like are placed in a substantially rectangular frame formed by the base frame 19.
Thereby, the frame of the tea garden management machine which can straddle the teacup is formed.

  The right crawler traveling device 31 and the left crawler traveling device 32 are devices that exhibit driving force and travel on the ground of a tea garden. For example, in the right crawler traveling device 31, a traveling motor 35 and a driven shaft 34 are provided in the crawler housing 33 so as to be separated from each other in the front-rear direction. An annular endless belt 36 is stretched between the travel motor 35 and the driven shaft 34. The traveling motor 35 is driven by the hydraulic pressure supplied from the hydraulic device in accordance with the operation of the handle 26 and the lever 27. The tea leaf plucking machine 1 moves forward, retreats, turns right, and turns left by independently driving the right crawler traveling device 31 and the left crawler traveling device 32 to rotate.

The cutting blade device 41 prunes the tea leaves of the teacup that the traveling machine body 10 straddles. The cutting blade device 41 includes a cutting blade housing 42 and a cutting blade member 43.
The cutting blade housing 42 is formed to be slightly longer than the maximum width of the traveling machine body 10.
The cutting blade member 43 is disposed in the cutting blade housing 42 and is curved so that the upper surface of the teacup has an arc shape. The cutting blade member 43 is driven by the hydraulic circuit described above.
The cutting blade device 41 is provided on the lower side of the base frame 19 so as to be movable up and down. The cutting blade device 41 cuts the tea leaves on the upper surface of the teacup by the driven cutting blade member 43 at the adjusted height.

The transport device 51 transports the tea leaves cut by the cutting blade device 41 to the container device 61 by blowing air. The transport device 51 includes a duct 52 and a fan 53.
The duct 52 connects the cutting blade device 41 and the container device 61.
The fan 53 is provided on the base frame 19 side by side with the drive device 28 and generates an air flow from the cutting blade device 41 toward the container device 61 in the duct 52 through a tube (not shown).
The transport device 51 transports the tea leaves cut by the cutting blade device 41 to the container device 61 by the air flow generated by the fan 53 in the duct 52.

  The cutting blade device 41 and the conveying device 51 are attached to the lifting device 81 together with the container device 61, for example. The container device 61, the transport device 51, and the cutting blade device 41 are lifted and lowered together with the lifting device 81 with respect to the traveling machine body 10.

Then, the tea leaf plucking machine 1 cuts the tea leaves from the teacup by the cutting blade device 41 while running across the teacup by the traveling machine body 10. The harvested tea leaves are transported to the container device 61 by the transport device 51. Thereby, the cut tea leaves are accommodated in the container device 61.
Further, for example, when the container device 61 is filled with the cut tea leaves, the tea leaf picking machine 1 lifts the container device 61 high by, for example, the lifting device 81, and the platform 92 of the truck 91 is below the lifted container device 61. It moves so that it may be located, and the container apparatus 61 is opened. Thereby, the tea leaf plucking machine 1 can drop the tea leaves in the container device 61 from the container device 61 and transfer them to the loading platform 92 of the truck 91. The tea leaf plucking machine 1 that has discharged tea leaves from the container device 61 can reaper tea leaves again from the teacups.

By the way, in such a tea leaf picking machine 1, in order to transfer tea leaves from the container device 61 to the loading platform 92 of the truck 91, it is necessary to open and close the container device 61.
As a method for opening and closing the container device 61, for example, it is conceivable to open the bottom surface of the lifted container device 61 downward. However, in this case, the opened bottom surface hangs down from the container device 61. In order to prevent the drooping bottom surface from hitting the tea leaves of the loading platform 92 of the truck 91, the lifting device 81 must lift the container device 61 by an amount corresponding to the height of the drooping bottom surface, for example. The burden on the lifting device 81 is increased.
In addition to this, for example, it is conceivable to open the back of the substantially cubic container device 61 downward and to tilt the entire container device 61 backward. In this case, the container device 61 pivots backward greatly in a state where it is lifted high. The burden on the opening / closing mechanism 76 for tilting the container device 61 is large. The structure of the opening / closing mechanism 76 for driving the heavy container device 61 is also complicated. Further, since the center of gravity of the container device 61 also moves rearward when it is largely tilted backward, it is necessary to give the lifting / lowering device 81 rigidity or the like so that the container device 61 can be supported at the moved center of gravity. There is. The burden on the lifting device 81 and the opening / closing mechanism 76 is increased.
Furthermore, for example, it is conceivable to shift the five surfaces other than the bottom surface of the substantially cubic container device 61 backward. In this case, since the state of the bottom surface on which the tea leaves in the container device 61 are stacked does not change before and after opening and closing, the tea leaves in the container device 61 tend to remain stacked on the bottom surface. A large amount of tea leaves tend to remain in the container device 61. In order to prevent a large amount of tea leaves from remaining on the bottom surface, a movable member that sweeps the bottom surface by a powerful opening / closing mechanism 76 is required. Moreover, when the tea leaves remaining on the bottom surface are swept in this way, the swept tea leaves are easily damaged. Further, in order to form a large opening on the side of the bottom surface by shifting the five surfaces other than the bottom surface of the container device 61 rearward, it is necessary to largely shift the portions other than the bottom surface of the container device 61 rearward. In this case, the center of gravity of the container device 61 is also moved rearward, and the load on the lifting device 81 and the opening / closing mechanism 76 is increased.

Thus, in the tea leaf plucking machine 1, the tea leaves accommodated in the container device 61 can be suitably loaded onto the loading platform 92 of the truck 91 while suppressing an increase in the burden on the lifting device 81 and the opening / closing mechanism 76. It is requested to do.
Therefore, in the present embodiment, the elevating device 81 attached to the traveling machine body 10 so as to be movable up and down, and the container device 61 attached to the elevating device 81 and containing tea leaves are devised. The structure of the container device 61, the opening / closing mechanism 76, the lifting mechanism, etc. are devised.

FIG. 2 is an explanatory diagram of the structure of the container device 61 in FIG.
FIG. 2 illustrates a container main body 62 of the container device 61. In addition, the container device 61 has an opening / closing mechanism 76.
The container main body 62 includes a base casing 63 and a movable casing 68. By closing the movable casing 68 with respect to the base casing 63, the container body 62 forms a substantially cubic-shaped accommodation space that can accommodate tea leaves. The container main body 62 is formed in a substantially cubic shape by closing the movable casing 68 from the rear side with respect to the base casing 63.

The base housing 63 includes a front surface portion 64, a right scattering prevention plate 65, and a left scattering prevention plate 66. The base housing 63 is fixed to the lifting device 81.
The front part 64 has a substantially rectangular plate shape. The front surface portion 64 corresponds to the front surface of the container body 62 having a substantially cubic shape. The front plate is formed on a smooth surface as a whole. An opening 67 communicating with the duct 52 of the transport device 51 is formed in the upper part of the front plate.
Further, the front surface portion 64 of the present embodiment is wider in the left-right width than the movable housing 68.
The right scattering prevention plate 65 is provided along the vertical direction at the right edge of the front portion 64 having a substantially rectangular plate shape. The right scattering prevention plate 65 protrudes rearward from the front surface portion 64. As shown in FIG. 1B, the right scattering prevention plate 65 is formed with a large number of through holes 74 for ventilation.
The left scattering prevention plate 66 is provided along the vertical direction at the left edge of the front portion 64 having a substantially rectangular plate shape. The left scattering prevention plate 66 protrudes rearward from the front surface portion 64. The left scattering prevention plate 66 is formed with a number of through holes 74 for ventilation.
Thus, the base housing 63 has a substantially U-shaped cross section when viewed from above by the front surface portion 64, the right scattering prevention plate 65, and the left scattering prevention plate 66. The base housing 63 can be formed, for example, by bending both ends of a long metal plate in the left-right direction backward in the same direction.
The right scattering prevention plate 65 and the left scattering prevention plate 66 may be connected to both left and right ends of the front surface portion 64 using a hinge or the like so as to be foldable with respect to the front surface portion 64. Further, the right scattering prevention plate 65 and the left scattering prevention plate 66 may be provided so as to be removable from the front surface portion 64.

The movable casing 68 has a bottom surface portion 69, a rear surface portion 70, a right surface portion 71, a left surface portion 72, and an upper surface portion 73.
The bottom surface portion 69, the rear surface portion 70, the right surface portion 71, the left surface portion 72, and the upper surface portion 73 may each be formed of, for example, a substantially rectangular plate material. These five surfaces can be formed into a box shape without a front surface. The bottom surface portion 69, the rear surface portion 70, the right surface portion 71, the left surface portion 72, and the upper surface portion 73 correspond to the bottom surface, the rear surface, the right surface, the left surface, and the upper surface of the substantially cubic container body 62, respectively.
A large number of through holes 74 for ventilation are formed in plate members used for the bottom surface portion 69, the rear surface portion 70, the right surface portion 71, the left surface portion 72, and the upper surface portion 73. As a result, the container body 62 having a substantially cubic shape is formed such that a portion other than the front surface portion 64 has a ventilation structure.
In addition, the movable housing 68 may be configured by a substantially cubic frame and a mesh cloth attached to the five surfaces of the frame. In this case, the movable casing 68 has a bottom surface portion 69, a rear surface portion 70, a right surface portion 71, a left surface portion 72, and an upper surface portion 73 made of mesh cloth.
Moreover, the movable housing 68 may be provided so as to be foldable using a hinge or the like. Further, the movable casing 68 may be provided so as to be disassembled.

The front surface 64 of the base housing 63 is located on the front side of the five movable housings 68 having no front surface. With this arrangement, the movable casing 68 and the base casing 63 are connected by a hinge 75 at their upper mating portions as shown in FIG. 1 (B). The movable casing 68 is rotatably attached to the base casing 63 with the upper edge on the base casing 63 side as the center of rotation.
Thereby, the substantially cubic container main body 62 of FIG. 1 (B) is formed. Further, with the container main body 62 closed, the right scattering prevention plate 65 is located outside the right surface portion 71 of the movable casing 68 and overlaps the right surface portion 71. The left scattering prevention plate 66 is located outside the left surface portion 72 of the movable casing 68 and overlaps the left surface portion 72.

FIG. 3 is an explanatory diagram of the container device 61 that is a portion that is movable with respect to the traveling machine body 10 in FIG.
In FIG. 3, a container main body 62 and an opening / closing mechanism 76 are illustrated as the container device 61. The opening / closing mechanism 76 is illustrated by a dotted line. Further, together with the container device 61, an elevating device 81, a cutting blade device 41, and a transport device 51 are illustrated. As the traveling machine body 10, a right rear column part 16 and a right front and rear frame 20 are illustrated by dotted lines.

The opening / closing mechanism 76 drives the movable casing 68 relative to the base casing 63 to open / close the container main body 62.
The opening / closing mechanism 76 includes a right opening / closing cylinder 77 and a left opening / closing cylinder. The right opening / closing cylinder 77 and the left opening / closing cylinder are, for example, hydraulic cylinders.
The right opening / closing cylinder 77 is disposed between the right scattering prevention plate 65 of the base casing 63 and the right surface portion 71 of the movable casing 68. One end of the right opening / closing cylinder 77 is attached to the right scattering prevention plate 65, for example. The other end of the right opening / closing cylinder 77 is attached to the right surface portion 71.
The left opening / closing cylinder is provided in a state corresponding to the right opening / closing cylinder 77. That is, the left opening / closing cylinder is disposed between the left scattering prevention plate 66 of the base casing 63 and the left surface portion 72 of the movable casing 68. One end of the left opening / closing cylinder is attached to, for example, the left scattering prevention plate 66. The other end of the left opening / closing cylinder is attached to the left surface portion 72.
When the right opening / closing cylinder 77 and the left opening / closing cylinder are contracted, the movable casing 68 hits the base casing 63. For example, as shown in FIG. 1B, the container main body 62 is closed.
Further, when the right opening / closing cylinder 77 and the left opening / closing cylinder are extended, the entire movable casing 68 is rotated clockwise in FIG. 3 around the upper edge of the base casing 63 side. The movable housing 68 rotates so that the whole is lifted rearward and upward. The opening / closing mechanism 76 rotationally drives the movable casing 68 closed with respect to the base casing 63 so as to lift rearward and upward. The bottom surface portion 69 is rotationally driven rearward and upward about the upper edge of the base housing 63 side. As a result, the container body 62 opens.
On the contrary, when the right opening / closing cylinder 77 and the left opening / closing cylinder are contracted, the entire movable casing 68 rotates counterclockwise in FIG. 3 around the upper edge of the base casing 63 side. The movable casing 68 rotates so that the entire body is pushed forward and downward. Finally, the container body 62 is closed.
Thus, in this embodiment, the container main body 62 can be opened and closed with only two hydraulic cylinders including the right opening and closing cylinder 77 and the left opening and closing cylinder. Further, since the pressure of the hydraulic cylinder directly acts on the movable casing 68 without using a link or an arm, the movable casing 68 is pressed against the base casing 63 when the container main body 62 is closed. Can do. The container main body 62 is firmly closed and hardly wobbles.

  The lifting device 81 has a right lifting platform 82, an upper right arm 83, a lower right arm 84, and a right lifting cylinder 85. In addition, the lifting device 81 has a left lifting platform, an upper left arm, a lower left arm, and a left lifting cylinder, which are not shown, corresponding to the right side shown in the drawing.

The right lifting platform 82 is attached to the right rear column portion 16 of the rear portal frame 15 of the traveling machine body 10 so as to be movable up and down. The right lifting platform 82 has a hydraulic lifting mechanism inside, and can be moved up and down along the right rear column portion 16 or the left rear column portion 17 by hydraulic pressure.
The left lifting platform is attached to the left rear column portion 17 of the rear portal frame 15 of the traveling machine body 10 so as to be movable up and down.

The upper right arm 83 is a metal rod-shaped member. One end of the rod-shaped upper right arm 83 is rotatably attached to the right elevator 82. The other end of the upper right arm 83 is rotatably attached to the base housing 63 of the container main body 62. In FIG. 3, the other end of the upper right arm 83 is attached to the right scattering prevention plate 65.
The upper left arm is a metal bar-like member, and is rotatably attached between the left lifting platform and the left scattering prevention plate 66 of the container main body 62.

The lower right arm 84 is a metal rod-shaped member. The lower right arm 84 is longer than the upper right arm 83. One end of the rod-like lower right arm 84 is pivotally attached to the right lifting platform 82 below the upper right arm 83. The other end of the lower right arm 84 is rotatably attached to the base casing 63 of the container main body 62. In FIG. 3, the other end of the lower right arm 84 is attached to the right scattering prevention plate 65 on the lower side of the upper right arm 83.
The lower left arm is a metal bar-like member, and is attached to the lower side of the upper left arm so as to be rotatable between the left elevator and the left scattering prevention plate 66 of the container main body 62.

The right elevating cylinder 85 and the left elevating cylinder are, for example, hydraulic cylinders. The right elevating cylinder 85 is attached between the lower end portion of the right elevating platform 82 and the central portion of the lower right arm 84. The left lifting cylinder is attached between the lower end of the left lifting platform and the central portion of the lower left arm.
When the right elevating cylinder 85 and the left elevating cylinder are contracted, the container main body 62 descends and is positioned immediately after the rear portal frame 15 of the traveling machine body 10, for example, as shown in FIG. The opening 67 of the front surface portion 64 of the container main body 62 communicates with the duct 52 of the transport device 51. The tea leaves cut by the cutting blade device 41 can flow into the container main body 62 through the duct 52 of the transport device 51. Further, the air flow for conveying the tea leaves flows to the rear of the container body 62 due to the ventilation structure of the container body 62. Only the tea leaves remain in the container body 62. Further, since eddy currents are not easily generated in the container main body 62, the tea leaves in the container main body 62 are hardly painful.
When the right elevating cylinder 85 and the left elevating cylinder are extended, the upper right arm 83 and the lower right arm 84 are rotated clockwise in FIG. Further, the upper left arm and the lower left arm rotate clockwise in FIG. 3 around the left elevator. Thereby, the container main body 62 is lifted toward the upper right in the drawing, that is, the rear upper direction.
Further, the container main body 62 can be lifted further through the horizontal position. In the most lifted position, as shown in FIG. 3, the front surface portion 64 of the container main body 62 is located on the lower side of the container main body 62 and tilts rearward and downward.
On the contrary, when the right elevating cylinder 85 and the left elevating cylinder are contracted, the upper right arm 83 and the lower right arm 84 are rotated counterclockwise in FIG. Further, the upper left arm and the lower left arm rotate counterclockwise in FIG. 3 around the left elevator. The container main body 62 descends counterclockwise. Finally, the container main body 62 is positioned immediately after the rear portal frame 15 of the traveling machine body 10.
Thus, in this embodiment, the container main body 62 can be raised / lowered with only two hydraulic cylinders. Further, since the pressure of the hydraulic cylinder directly acts on the upper right arm 83, the lower right arm 84, the upper left arm and the lower left arm, the container main body 62 may be pressed against the traveling machine body 10 when the container main body 62 is lowered. it can. The container main body 62 is firmly fixed to the traveling machine body 10. The container body 62 is unlikely to wobble.

Next, an example of an operation for transferring the tea leaves accommodated in the container main body 62 to the loading platform 92 of the truck 91 will be described.
FIG. 4 is an explanatory view showing a state in which the container device 61 is raised to the upper part of the traveling machine body 10 in order to reload the tea leaves in the container device 61 to the loading platform 92 of the truck 91 in the tea leaf picking machine 1 of FIG. is there.
FIG. 5 is an explanatory diagram showing a state in which the various arms 83 and 84 of the lifting device 81 are rotated rearward and upward from the upper position of the traveling machine body 10 of FIG.
FIG. 6 is an explanatory view showing a state in which the bottom of the container device 61 is opened rearward and upward by rotating the movable casing 68 of the container device 61 so as to be lifted rearward and upward at the highest position of FIG. 5.

As shown in FIG. 1 (B), the tea leaf plucking machine 1 sets the container body 62 in the lowered position, travels across the teacup in this state, and plucks tea leaves.
When the tea leaves are filled in the container main body 62, the tea leaf picking machine 1 moves to the side of the truck 91 in order to move the tea leaves accommodated in the container main body 62 to the loading platform 92 of the truck 91, as shown in FIG. Moving.
The tea leaf plucking machine 1 moved to the side of the loading platform 92 of the truck 91 operates the lifting device 81. The right lifting platform 82 rises along the right rear column portion 16 of the rear portal frame 15 of the traveling machine body 10. The left lifting platform ascends along the left rear column portion 17 of the rear portal frame 15 of the traveling machine body 10. Thereby, as shown in FIG. 4, the lifting device 81 moves to the upper part of the traveling machine body 10. The container main body 62, the cutting blade device 41, and the transport device 51 of the container device 61 attached to the lifting device 81 also move upward.
After the lifting device 81 is moved upward, the tea leaf plucking machine 1 extends the right lifting cylinder 85 and the left lifting cylinder. Thereby, the upper right arm 83 and the lower right arm 84 rotate clockwise around the right elevator 82. The upper left arm and lower left arm rotate clockwise about the left elevator. Thereby, the container main body 62 of the container apparatus 61 rises while rotating clockwise. Ascend rearward and upward. And it reaches | attains the highest position shown in FIG. The container main body 62 of the container device 61 is located above the edge of the loading platform 92 of the truck 91.
After lifting the container main body 62 above the edge of the loading platform 92 of the truck 91, the tea leaf picking machine 1 moves backward and places the container main body 62 on the loading platform 92 of the truck 91 as shown in FIG.
Next, the tea leaf plucking machine 1 extends the right opening / closing cylinder 77 and the left opening / closing cylinder of the opening / closing mechanism 76. Thereby, the movable casing 68 closed with respect to the base casing 63 is rotationally driven so as to be lifted rearward and upward. The bottom surface, back surface, right surface, left surface, and top surface of the container main body 62 move rearward with respect to the front surface. The tea leaves accommodated in the container main body 62 naturally fall due to their own weight from the opening formed in the bottom of the container main body 62 as the bottom surface of the container main body 62 moves. The fallen tea leaves are transferred to the loading platform 92 of the truck 91 and loaded.
As shown in FIG. 6, the opening / closing mechanism 76 rotates the entire movable casing 68 in a state where the front face portion 64 is inclined toward the rear lower direction on the lower side of the container main body 62, so that the rear Lift along the upward direction. Thereby, the tea leaves accommodated in the container main body 62 fall along the inclination of the front surface portion 64 while falling toward the front surface portion 64. For example, even if tea leaves are entangled in the container main body 62, they can be broken and dropped. Further, since the bottom surface of the container main body 62 is also inclined forward and downward, the tea leaves on the bottom surface of the container main body 62 can also fall toward the front surface portion 64. The tea leaves in the container main body 62 can fall from the container main body 62 by natural fall.

As described above, in the present embodiment, the container main body 62 of the container device 61 includes the base housing 63 on the lifting device 81 side and the movable housing 68 that can be opened and closed with respect to the base housing 63 from the rear side. The movable housing 68 has at least a bottom portion such as the bottom surface 69 of the container main body 62, and the opening / closing mechanism 76 is rotationally driven to lift the movable housing 68 closed with respect to the base housing 63 rearward and upward. Then, the bottom of the container main body 62 is opened rearward and upward. Therefore, the bottom of the opened container main body 62 is unlikely to hang down below the container main body 62.
On the other hand, for example, if the bottom surface 69 of the container main body 62 is opened downward, the bottom surface 69 of the opened container main body 62 hangs down from the container main body 62. In this case, in order to prevent the drooping bottom surface portion 69 from hitting the tea leaves of the loading platform 92 of the truck 91, the lifting device 81 needs to lift the container main body 62 by an amount corresponding to the bottom surface portion 69 depending from the container main body 62. There is. In the present embodiment, this can be suppressed.
Further, in the present embodiment, the opening / closing mechanism 76 does not drive the entire container body 62 but drives only the movable casing 68 therein. Moreover, the movable housing 68 is lifted rearward and upward.
On the other hand, for example, when the entire container main body 62 is tilted backward, the size and weight of the driven portion increase, and the burden on the lifting device 81 and the opening / closing mechanism 76 increases. It is necessary to give the elevating device 81 and the opening / closing mechanism 76 high rigidity or to use a complicated opening / closing mechanism 76. In the present embodiment, this can be suppressed. For example, since the opening / closing mechanism 76 only rotationally drives the movable casing 68, the opening / closing mechanism 76 can have a simple structure. Compared to the case where the entire container body 62 is tilted backward, the number of parts can be significantly reduced. Moreover, since the opening / closing mechanism 76 has a simple structure, play in the opening / closing mechanism 76 is reduced in the closed container body 62, and the movable casing 68 is less likely to wobble in the closed container body 62.
Thus, in this embodiment, the tea leaves accommodated in the container main body 62 of the container device 61 can be suitably reloaded onto the loading platform 92 of the truck 91 while suppressing an increase in the burden on the lifting device 81 and the opening / closing mechanism 76. .
In addition, in the present embodiment, a portion that becomes the bottom of the container main body 62 is provided in the movable casing 68, and the bottom of the container main body 62 can be opened. Therefore, the tea leaves accommodated in the container main body 62 can be efficiently loaded onto the loading platform 92 of the truck 91 from the bottom of the opened container main body 62 due to natural fall. Even when the tea leaves are reloaded due to a natural fall, the tea leaves hardly remain in the container body 62.

Further, in the present embodiment, the movable casing 68 has at least a bottom surface portion 69 serving as a bottom surface of the substantially cubic container main body 62 and a rear surface portion 70 serving as at least a lower portion of the rear surface of the container main body 62. Then, the entire movable casing 68 can be rotated so as to be lifted rearward and upward. Therefore, in the movable casing 68 that is lifted rearward and upward, the bottom surface portion 69 rotates around the rear surface portion 70, and the opened bottom surface portion 69 is lifted from the lower edge of the container main body 62. The opened bottom portion 69 is unlikely to fall from the lower edge of the container body 62. Even if tea leaves are loaded on the loading platform 92 of the truck 91, the bottom surface of the container main body 62 can be opened, and the tea leaves accommodated in the container main body 62 can be additionally loaded. Occurrence of a situation in which the bottom surface of the container main body 62 does not open due to interference with the tea leaves loaded on the loading platform 92 can be suppressed.
Further, since the bottom surface portion 69 is opened so that the bottom surface portion 69 rotates around the rear surface portion 70, a wide opening is secured at the bottom portion of the opened container main body 62. Tea leaves can be dropped efficiently from a wide opening.
On the other hand, if the opening area is not sufficiently large, for example, the tea leaves are easily caught in the container body 62. In the present embodiment, occurrence of such a situation can be suppressed. As a result, in this embodiment, it is possible to transfer the tea leaves accommodated in the container main body 62 to the loading platform 92 without leaving the container main body 62 by simply opening the movable casing 68. Manual assistance is not required, and the work time and workability when reloading tea leaves can be improved.

  In the present embodiment, the right scattering prevention plate 65 and the left scattering prevention plate 66 of the base casing 63 overlap the right surface portion 71 and the left surface portion 72 of the movable casing 68 with the container main body 62 closed. Therefore, in order to obtain a wide opening, the rear surface, the right surface, and the left surface of the container main body 62 are formed on the movable casing 68 together with the bottom surface of the container main body 62, and the entire movable casing 68 is rotated to be lifted rearward and upward. Nevertheless, it is difficult to form openings on the left and right sides of the opened container body 62. As a result, the tea leaves are less likely to leak from the left and right sides of the opened container body 62 even though the container body 62 is configured to be greatly opened. The tea leaves accommodated in the container main body 62 are efficiently transferred from the bottom of the opened container main body 62 to the loading platform 92 of the truck 91 by natural fall while preventing the tea leaves from leaking from the left and right of the opened container main body 62. Can do. Moreover, not only the rear surface of the container main body 62 but also the right and left surfaces are movable casings 68, whereby the rigidity of the movable casing 68 that is driven to open and close can be increased.

Moreover, in this embodiment, the raising / lowering apparatus 81 lifts the container main body 62 so that the front surface part 64 may become the lower side of the container main body 62, and may incline toward the back lower direction. The movable casing 68 has a bottom surface portion 69, a rear surface portion 70, a right surface portion 71, and a left surface portion 72, and an upper surface portion 73 that serves as an upper surface of the substantially cubic container body 62. The entire movable casing 68 is rotationally driven in a state where 64 is inclined rearward and downward on the lower side of the container main body 62, and the entire movable casing 68 is lifted along the rearward and upward direction. Therefore, the tea leaves accommodated in the container main body 62 are collapsed as a whole on the inclined front part 64 by opening the movable casing 68, and along the inclination in the rear lower direction of the front part 64 while collapsing. Move. As a result, the tea leaves accommodated in the container main body 62 can efficiently fall from the rear end of the front surface portion 64 along the inclination of the front surface portion 64. Even when the container body 62 is lifted high, the tea leaves hardly remain in the container body 62.
Moreover, in this embodiment, the height which the container main body 62 lifts can be selectively used for a low position and a high position according to the quantity of the tea leaves in the loading platform 92, for example. Compared to the case where the container main body 62 can be lifted only to the horizontal position, a large amount of tea leaves can be transshipped to the loading platform 92.

  Moreover, in this embodiment, in order to convey the cut tea leaves to the container main body 62, the container main body 62 is formed in a ventilation structure, and the tea leaves cut from the teacup by the air blow of the conveying device 51 are conveyed to the container main body 62. . And although the container main body 62 is made into the ventilation structure in this way, the front face portion 64 is formed on a generally smooth surface including the lower portion, though the tea leaves are easily caught on the container main body 62. In addition, since the ventilation structure is provided in a portion other than the front surface portion 64, the tea leaves in the container main body 62 are easily slid down on the inclined front surface portion 64 which is not the ventilation structure. As a result, the tea leaves in the container main body 62 can be transferred to the loading platform 92 by natural fall. Tea leaves hardly remain in the container main body 62. A series of steps of transporting and storing the harvested tea leaves to the container main body 62 and transferring them from the container main body 62 to the truck 91 can be performed efficiently.

Further, in the present embodiment, for example, the lower right arm 84 of the lifting device 81 is longer than the upper right arm 83. Therefore, when the container main body 62 is lifted by rotating the upper right arm 83 and the lower right arm 84 rearward upward, The front surface portion 64 can be inclined to the rear lower direction while being on the lower side of the container main body 62.
Moreover, in the present embodiment, for example, the container main body 62 is lifted by rotating the upper right arm 83 and the lower right arm 84 from the lower side to the upper side. 31 and the left crawler traveling device 32 can be lifted away from the rear ends. Therefore, the space | interval with the lifted container main body 62 is securable on the back side of the traveling body 10. Accordingly, the lifted container main body 62 can be brought closer to the center of the loading platform 92 of the truck 91. There is a margin in the distance between the traveling machine body 10 for transferring tea leaves and the truck 91.
