The tip of the flexible container hanging member 751a near the vehicle body, such as a pin for attaching the flexible container 650 in cooperation with a ring member or a hole provided in the flexible container 650, is directed obliquely upward to the right when viewed from the rear of the vehicle body. Therefore, the flexible container hanging member 751a is successfully removed in the direction indicated by the arrow X2 when viewed from the flexible container 650 in the vicinity of the central lower side of the conveyor 520, and the flexible container 650 is not broken. Flexible container suspension members 751a and 751b receive a downward container load when flexible container 650 is suspended and slide off flexible container 650 when flexible container 650 is moved laterally.

The mounting table 610 is a table attached to the vehicle body 100 so as to be tiltable, on which the flexible container 650 is mounted.

Next, mainly referring to FIG. 1, the configuration and operation of the carrot harvesting vehicle according to the present embodiment will be described more specifically.

When the height of the conveyor end portion 521 increases as the conveyor device 500 rotates, the hanger holding crane arm mechanism 700 rotates in the upward direction as the conveyor device 500 rotates. An abutment member 510 is provided on the conveyor device 500 to abut against the hanger holding crane arm mechanism 700 .

A more specific description is as follows, with reference to FIGS.

Figures 7 and 8 are enlarged rear views of Figures 3(a) and (b), respectively.

The abutting member 510 is provided on the conveyor 520 and the like as a guide plate like a projection for raising the crane arm 720, which is the crane arm on the root side, at an intermediate position in the range in which the conveyor 520 rotates. When the crane arms 720 and 730 are stowed, they can be folded so as not to be a hindrance by projecting into the side space and the upper space. To facilitate this, an abutment member 510 is provided. Therefore, not only the effective space utilization mentioned above, but also labor reduction in crane arm deployment is realized.

Of course, the abutment member 510 may be provided on the conveyor 520 or the like as a roller for raising the crane arm 720 as well.

A biasing member 710 is provided to bias the hanger retaining crane arm mechanism 700 in such a manner that the hanger retaining crane arm mechanism 700 is rotated in the lifting direction regardless of the rotation of the conveyor device 500 .

More specifically, with reference to FIGS. 9 and 10, which are enlarged rear views (parts 5 and 6) of a carrot harvesting vehicle according to an embodiment of the present invention, it is as follows.

Figures 9 and 10 are enlarged rear views of Figures 3(d) and (f), respectively.

The crane arm 720 is rotatable by changing its posture in a direction that reduces the angle θ between the longitudinal direction of the conveyor 520 and the longitudinal direction of the crane arm 720 . Therefore, even when the height of the conveyor end portion 521 is lower than that of the bag opening of the flexible container 650, the harvested carrots are less likely to be crushed by the conveyor 520. Even if the crane arm 720 comes into contact with the conveyor 52 again and then descends further, the angle θ changes. be.

It is often desirable that the biasing direction of the biasing member 710, such as a torque spring attached to the pivot point, be such that the angle .theta. This is because not only is it difficult for the above-described pressing of carrots to occur, but the hanger holding crane arm mechanism 700 is naturally removed from the flexible container 650 that has been lowered to the field ground as the container hanging ring is removed. because it comes off. Further, even if the conveyor 52 is not lifted, the crane arm length can be operated without catching the flexible container 650 .

This amount of biasing is such that even when conveyor 52 has not yet been raised at the start of harvesting and the height of conveyor end 521 is small, the bag mouth of flexible container 650 is raised to allow harvested carrots to be flexible. It is often desirable to have an amount that does not protrude outside of container 650 . In addition, since the amount of bias is large to some extent and the opening of the flexible container 650 is naturally elevated, the carrots stored in the flexible container 650 are less likely to fall out of the flexible container 650 .

<1> In a so-called overhanging hanger arm type lateral unloading crane, the crane arm 720, which is the crane arm on the root side, and the crane arm 730, which is the crane arm on the tip side, can be bent in an inverted V shape. Thus, the mounting space for the cylinder 1110 is effectively formed.

FIG. 11A is a right side view of a carrot harvesting vehicle according to a modified example (first) of the present invention, and a plan view of a carrot harvesting vehicle according to a modified example (first) of the present invention. With reference to FIG. 11(b) and FIG. 11(c), which is a rear view of a carrot harvesting vehicle according to a modified example (first) of the present invention, a more specific description is as follows. be.

The four flexible container hanging members 751a and 751b, which are hanging hooks attached to the hanger 750, are subjected to a force in the direction in which they do not open due to the load when the hanger is lifted.

During harvesting, when the cylinder 1110 is not fully extended and the crane arm 720 is folded so that the angle between the crane arm 720 and the crane arm 730 is not too great, the assembly of the hanger 750 is positioned at the conveyor exit at the conveyor end 521. , and the overlap between the bag mouth of the flexible container 650 and the outlet of the conveyor terminal 521 is sufficiently ensured that carrots falling from the conveyor terminal 521 are received by the flexible container 650 and spilled. Hard to get out.

Lifting and lowering of the conveyor 52 and crane arm extension and deployment of the hanger holding crane arm mechanism 700 that also utilizes the cylinder 1110 are performed, for example, from a joystick device 1120 attached to the front side of the vehicle body 100 beside the driver's seat. at the user's instruction.

A joystick device 1120 realizes a so-called one-lever operation in the longitudinal direction and lateral direction of the vehicle indicated by four arrows.

As for the operation lever for such one-touch lever operation, an operation restraint is introduced so that the elevation of the conveyor 52 and the extension of the crane arm 730 using the cylinder 1110 are not performed at the same time. Therefore, it is difficult for the actuators for raising and lowering the conveyor 52 and extending the crane arm 730 to generate large currents intensively.

The crane arm 730 is provided with a so-called play on the upper side, which is the folding storage side. may be performed on conveyor 52 .

A light device 1130 is provided on the hanger holding crane arm mechanism 700 for nighttime illumination.

The light device 1130 is provided, for example, in the middle of the crane arm 730 or in the vicinity of the rotation fulcrum position on the root side. can illuminate the interior of the

The functionality of the side unloading crane described above is utilized for bag collection and bag loading of the flexible container 650 lowered to the field ground so that the harvesting operation can be done without a wheel loader vehicle.

Such bag collection is performed not by locking and suspending the so-called bag ear straps of the flexible container 650, but by locking and suspending the flexible container 650 with the bag outer straps, and utilizing the locking to the hanger 750. may be broken.

The unlocking handle 1140 of the hanger 750 can be used as a hook for locking suspension of the bag outer sling described above.

When the vehicle body 100 is traveling, the operation of the joystick device 1120 or the like is checked so that the operation of the crane system of the hanger holding crane arm mechanism 700 is restricted.

As for the restrictions on the operation of such a crane system, for example, the operation of the crane arm 730, which is the crane arm on the tip side, is restrained, but the operation of the conveyor 52 is not restrained.

For example, a condition that the parking brake switch is on can be used as a check condition for operation of the crane arm 730 .

<2> The connecting portion between the crane arm 730 and the hanger 750 is freely rotatable so that the horizontality of the flexible container 650 is always maintained.

FIG. 12(a) is a right side view of a carrot harvesting vehicle according to a modified example (second) of the present invention, and a plan view of a carrot harvesting vehicle according to a modified example (second) of the present invention. 12(b) and FIG. 12(c), which is a rear view of a carrot harvesting vehicle according to a modified example (second) of the present invention, a more specific description is as follows. be.

A spare flexible container 1210 is provided on the hanger holding crane arm mechanism 700 to act as a spare bag for the flexible container 650 .

Because the preliminary flexible container 1210 is compactly folded and removably secured to crane arms 720 and 730 or the like, operations in the above-described side unloading crane operation and sorting are hindered due to the mounting of the preliminary flexible container 1210. do not have.

The slack of the flexible container 650 as well as the preliminary flexible container 1210 may be reduced by utilizing a spring or the like attached to the crane arm 720, which is the crane arm on the root side.

By using an inclination sensor (not shown) or the like attached to the vehicle body 100, a function of motion warning or motion stop in the operation of the unloading crane is realized.

Since the horizontality maintenance function of the vehicle body 100 is automatically turned on with the operation of the crane arm 730, which is the crane arm on the tip side, the vehicle body 100 is less likely to tilt toward the outside of the vehicle body where the flexible container 650 is suspended. There is almost no risk of the vehicle tipping over.

The spare flexible container 1210 is loaded so as to be laid on the bottom surface of the mounting table 610, which is also called a bucket.

The preliminary flexible container 1210 folded using a plurality of folds may be simply placed on the mounting table 610, but preferably the preliminary flexible container 1210 may In order not to jump excessively from the bottom surface of the mounting table 610, the mounting table 610 is loaded so as to firmly sandwich the mounting table 610 in the vertical direction.

Multiple spare flexible containers 1210 are conveniently prepared with such compact bag loading.

The attachment and detachment of the spare flexible container 1210 on the side of the vehicle body is easily performed from the outside of the vehicle body, which is the open end side of the mounting table 610 .

<3> The function of the horizontal unloading crane by extending the crane arm 730 described above is combined with the function of the mounting table 610, which is a so-called slide-type mounting table.

FIG. 13A, which is a right side view of a carrot harvesting vehicle according to a modified example (third) of the present invention, and a plan view of a carrot harvesting vehicle according to a modified example (third) of the present invention. 13(b), and FIG. 13(c), which is a rear view of a carrot harvesting vehicle according to a modified example (third) of the present invention, a more specific description is as follows. be.

Actuator 620 is an actuator attached to vehicle body 100 that tilts mounting table 610 .

The mounting table 610 is attached to the vehicle body 100 so as to be tiltable in the longitudinal direction of the vehicle body in such a manner that the flexible container 650 can slide down toward the front side or the rear side in the longitudinal direction of the vehicle body when unloading.

The actuator 620 is attached to the vehicle body 100 at a position where interference with the hanger holding crane arm mechanism 700 does not occur.

Since a front lowering method or a rear lowering method is adopted for raising and lowering the mounting table 610 , the function of the side lowering crane is not hindered by the actuator 620 .

Since the actuator 620 projects toward the rear side of the vehicle body 100 and is arranged so as to avoid the side surface of the mounting table 610, there is almost no interference with members such as the radiator cover when the mounting table 610 is retracted.

Actuator 620 may be provided by using a non-powered gas spring or the like to achieve a simple configuration.

The outer edge of the top surface of the mounting table 610 is flat, and hardly catches on the outer edge of the flexible container 650 during operation of the unloading crane.

When a so-called mini-container (not shown) is used, the length of the mounting table 610 in the longitudinal direction of the vehicle body is equal to the length of the flexible container 650 in the longitudinal direction of the vehicle body. is the added length. It is desirable that the right end of the mounting table 610 provided on the right side in the left-right direction of the vehicle body is provided with an edge on which only a portion of the mini-container is hooked. This is because when the flexible container 650 is moved sideways, the mini-containers placed beside the flexible container 650 are less likely to fall sideways due to friction and interference with the flexible container 650. Because it becomes.

INDUSTRIAL APPLICABILITY The crop harvesting vehicle of the present invention can reduce the occurrence of breakage of the flexible container due to snagging and the like, and is useful for the purpose of being used as a crop harvesting vehicle such as a carrot harvesting vehicle.
