[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment specifically configured based on the above technical idea will be described below with reference to the drawings.
[0010]
A configuration example of the self-propelled vegetable harvester will be described. FIG. 1 is a plan view of a self-propelled vegetable harvester according to a configuration example of the present invention, and FIG. 2 is a right side view of the self-propelled vegetable harvester.
[0011]
1 and 2, a self-propelled vegetable harvesting machine 1 includes a steering seat 4, a prime mover 5, a harvesting device 7, a sorting carrier, and a body supported by a traveling device including left and right crawlers 3 and 3. 8. A loading table 9 with an electric carrier for feeding containers is arranged and arranged.
[0012]
The left and right crawlers 3, 3 are provided with a transmission 12 at a center position thereof, and the transmission 12 receives a power of a prime mover 5 arranged below the steering seat 4 to constitute a traveling device. Note that another configuration of the traveling device includes a wheel-type variation configuration in which the right and left crawlers 3 and 3 are replaced with four front and rear wheels.
[0013]
The control seat 4 constitutes a driver boarding section together with the turning lever b, the shift lever c, and other control devices. The operator's boarding section controls the aircraft while visually observing the harvesting of the harvested material at the tip of the harvesting device 7 of the harvesting work unit arranged on one of the left and right sides of the aircraft (the figure shows an example of the left half side). In order to be able to do so, it is configured to face the front of the fuselage on the other side on the left and right (the figure shows an example on the right half side) opposite to the harvesting work section.
[0014]
The harvesting device 7 includes a vibrating soiler d for loosening the left and right soil of the harvested crop in the field to be captured by longitudinal vibration, and the like. By this, it drives integrally as a traveling harvesting system. The working unit is configured to be directed in the front-rear direction of the machine so that the harvest is sent from the harvesting device 7 to the sorting transporting machine 8 at the rear of the machine. At its foremost part, a vertical raising device e provided with a lug as necessary is provided.
[0015]
The harvesting device 7 is configured by arranging a not-shown nipping and conveying belt, an adjustment belt 16, a tapping belt 17, a rotary blade 14, a leaf discharge belt 18, and the like in parallel. The nipping and conveying belt is configured by arranging left and right belts that are in pressure contact with each other so as to feed a part of the vegetables (roots and leaves of root vegetables) in a suspended state and feed them backward. This is caused to make opposing orbits by the power of the prime mover 5, and by cooperating with the horizontal speed backward and the forward speed of the body, the harvest target is vertically pulled out of the field and taken into the machine.
[0016]
The pair of left and right adjustment belts 16, 16 are arranged in a substantially horizontal position below the end portions of the left and right nipping and conveying belts in order to align the holding position of the vegetables. The left and right tapping belts 17 and 17 switch the root and leaf portions of the root vegetable from the left and right nipping and conveying belts so as to maintain the upper set position of the shoulder of the root vegetable. The left and right rotary blades 14, 14 face the rear of the transporting end portions of the adjustment belts 16, 16, and constitute a cutting device 14 for cutting unnecessary portions of vegetables (cutting and removing root and stem portions of root vegetables from roots). I do. The cutting device 14 cuts the base of the foliage of the root vegetables that has been conveyed while being held between the left and right tapping belts 17, 17, and the cut root vegetables fall downward. The leaf discharge belts 18, 18 are provided further above the tapping belts 17, 17, and continue to pinch the roots and leaves of the root vegetables left after the cutting, convey them backward, and discharge them outside the machine (rearward of the machine body).
[0017]
In the case of harvesting head vegetables such as cabbage, the harvesting device 7 is provided with left and right rotary transport shafts having spiral grooves on the outer periphery and having an axial center extending in the front-rear direction, instead of the sandwiching transport belt. It is good to have a configuration.
[0018]
The sorting conveying machine 8 combines the residual leaf processing device 10 disposed below the left and right rotary blades 14 and the relay conveyor 11 for receiving the processed crop, and performs a certain process on the crop received from the harvesting device 7. Then, a transfer device to the harvested product receiving portion R is configured.
[0019]
The remaining-leaf processing device 10 includes a remaining-leaf processing roller 10b that intersects with the traveling direction of the conveyor belt 10a at approximately 45 degrees so that the conveyed material is wound on the upper surface of the conveyor belt 10a and sent to the side thereof. By arranging the cutting device 14 of the device 7 directly below the cutting device 14 in the transverse direction of the machine body, the main body portion is sent to the side relay conveyor 11 while separating the remaining leaves of the field crops in cooperation with the conveyor belt 10a. In addition, the said transfer apparatus may be a structure which does not equip this residual leaf processing apparatus 10 according to the kind and work form of the vegetables to be harvested, and in that case, it is directly from the cutting apparatus 14 to the conveying machine 8 for sorting. Configure to transport.
[0020]
The sorting transport machine 8 is configured by a belt conveyor or the like for enabling a sorting operation by an operator in a process of storing field crops such as carrots received from the harvesting device 7 in a container. For the drive, the remaining leaf processing device 10 and the relay conveyor 11 are combined as necessary, a power supply unit different from the prime mover, for example, a motor by a battery is provided, and an operation switch 8a for selectively operating or stopping the operation is provided. Place it near the operator. The sorting transporting machine 8 is arranged in the front and rear direction of the machine at a position adjacent to the harvesting device 7 at the rear part of the machine and receives supply of the harvested material from the residual leaf processing device 10 and the relay conveyor 11 while providing a space for the worker. 6 and the sorting work by the operator is enabled. A container dump or the like is provided in the harvested product receiving portion R at the end, and a container into which the harvested material is put is arranged. A seat S0 is provided on which the worker who has boarded the worker space 6 can sit during the sorting operation. As shown in FIG. 1, it is arranged above the loading table 9 so that an operator can sit sideways toward the sorting transport device 8.
[0021]
The loading table 9 is configured as a vegetable storage section for loading the container A containing the crop drawn out from the crop receiving section R to the side D and extending to the side of the pilot boarding section along the fuselage side end, The loading table 9 is provided with an electric carrier for feeding containers in order to sequentially accommodate the containers from the back. The carrier of the loading table 9 is systematized with the sorting transfer machine 8 by a power supply system independent of the power source of the traveling and harvesting system by a battery power source or the like, similarly to the sorting transfer machine 8, or in the vicinity of the worker. The operation and the stop can be selectively operated by the disposed operation switch 9a. Further, the loading table 9 is configured to be foldable when not used, that is, in order to reduce the space at the time of stopping in a garage or the like.
[0022]
Since the self-propelled vegetable harvesting machine 1 is configured as described above, the traveling devices 3 and 3 receive power supply from the prime mover 5 to travel and drive the machine body, and the harvesting unit of the harvesting device 7 is driven by the prime mover 5. Then, the vegetables in the field are harvested cooperatively with the traveling devices 3 and 3, and the vegetables are transferred to the harvest receiving portion R by the transfer devices 10, 11, and 8, and at least a part of the transfer portion 8 for the sorting operation. After being qualified and sorted by the worker, it is put into the container A and stored. When the container A is full, the sorting operation transfer unit 8 is temporarily stopped for container replacement, and the container A is pulled out from the crop receiving unit R into the vegetable storage unit S on the side D and newly renewed. Refill empty containers. Further, since the container A containing the harvest is aligned from the back of the loading table 9 by temporarily operating the container transport means by the electric carrier of the loading table 9, a large number of containers A can be easily handled. .
[0023]
At this time, since the sorting work transfer unit and the container transport means are driven by a power supply unit different from the power of the traveling harvesting system, the sorting work transfer unit 8 and the loading unit can be loaded without causing load fluctuation of the traveling harvesting system. The operation and stop of the table 9 can be performed at any time.
[0024]
Therefore, the self-propelled vegetable harvester having the above-described configuration enables stable extraction of vegetables in accordance with the traveling speed, and also enables wide and stable harvesting of vegetables to a high load state, as well as transfer. It is possible to ensure a simple operation of a series of operations from sorting and sorting containers by a single worker, without changing the container, without requiring any special staying means. In addition, by using an electric type, it is possible to easily form a system.
[0025]
Next, the configuration of the crop receiving section will be described. FIG. 3 shows a side view of the crop receiving portion. A container holder 21 is provided in the crop receiving part R so as to face the delivery end of the sorting work transfer part 8. The container holder 21 is bent in a substantially L-shape, and can be tilted by rotating around the support shaft 20, and can be returned to the horizontal position by increasing the container weight by contraction of the damper 20a or the spring. The container A is held in the tilted posture. The container holder 21 includes a holding unit 21a that holds the container A that receives the crops sent from the sorting operation transfer unit 8 and a standby unit 22 that tilts and holds the empty container B at an adjacent position. The standby unit 22 is configured as a shooter that is inclined upward at a predetermined angle α with respect to the holding unit 21a and guides the empty container B to the holding unit 21a.
[0026]
When the container A is held in the holding portion 21a of the container holder 21 having the above configuration, the empty container B is held in the standby portion 22 using the container A as a stopper. In this state, the entire container is tilted to the tilting position of the container holder 21U, and the container A is held in the tilted posture. Cracks and scratches can be prevented.
[0027]
After tilting the container holder 21 toward the horizontal position by the storage weight so as to return the position of the container A to the horizontal position according to the storage amount, when the container A is filled with the storage object, the container A is (Empty side of the paper surface) to open the crop receiving portion R, so that the empty container B temporarily fixed to the standby portion 22 by the container A moves to the harvest receiving portion R using the standby portion 22 as a shooter. I do.
[0028]
Therefore, when the container A receiving the crops sent from the sorting work transfer unit 8 is full, the empty container B is replenished by pulling out the container A to the side, and the container can be easily replaced with one touch. It becomes possible.
[0029]
Further, in the container holder 21, the inclination angle α of the standby portion 22 is formed in a range where the empty container B does not slide (for example, 15 degrees or less). In this case, the empty container B slides out at an angle obtained by adding the tilt angle of the entire container holder 21 to the tilt angle α of the standby portion 22. Therefore, after the container A is pulled out from the holding portion 21a, the entire container is tilted by a relatively small angle. The empty container B slides down from the standby portion 22 in the front direction without interfering with the container A, and is reliably set on the holding portion 21a.
[0030]
Therefore, when the container A of the holding unit 21a is used as a stopper, as shown in the plan view of the container holder showing the one-sided state of the empty container in FIG. The ends of the empty container B sliding down from the container may interfere with each other, and the one-sided contact may cause the empty container B to drop obliquely or be caught. However, with the above-described configuration, it is possible to prevent such an erroneous setting to the holding portion 21a. .
[0031]
Further, as shown in the side view (a) and the operation explanatory view (b) of the container holder according to another configuration example of FIG. 5, a fixed support portion 23 for supporting the empty container B is provided in the container holder 21, After the container A of the holding portion 21a is pulled out to the side D, the entire container holder 21 is tilted. In this case, when the empty container B reaches a position higher than the fixed support portion 23 due to the tilting of the entire container holder, the empty container B slides down toward the front thereof along the inclination of the standby portion 22 and is set in the holding portion 21a. Similarly, the empty container B can be reliably set on the holding portion 21a.
[0032]
Further, as shown in a cross-sectional view showing a configuration example of the container holder holding portion in FIG. 6, the holding portion 21a of the container holder 21 has a front surface of the empty container B that has entered the holding portion 21a from the standby portion 22 having a shooter function. The projection 25 is provided so as to face the side. The projection 25 hits above the middle position of the empty container B to enter, stops the empty container B, and positions the empty container B with respect to the holding portion 21a. Can be configured to be small.
[0033]
Further, as shown in the plan view of the container holder 21 shown in FIG. 7, when the full container A is pulled out from the crop receiving part R to the side D thereof, a predetermined amount is set from the side end of the waiting empty container B. The stopper 31 located below the container A is provided until the rear end of the container A in the drawing direction advances to the distance y. While the stopper 31 is located below the container A in the middle of being pulled out, the tilting operation of the container holder 21 is restricted. Therefore, since the tilting operation of the container holder 21 becomes possible only after the container A is completely pulled out, the container holder 21 is tilted during the operation of pulling out the container A, and the empty container B of the standby part 22 is held by the holding part. The empty container B can be reliably set on the holding portion 21a by avoiding sliding down to the container 21a and interference with the container A in the middle of drawing.
[0034]
Further, as shown in a side view showing a configuration example of the standby portion of the container holder in FIG. 8, a support shaft 21b is provided at an end of the holding portion 21a, and the standby portion 22 is pivoted up and down so as to be foldable. In addition, a restricting member 22a for defining a rotation range between the holding portion 21a and the standby portion 22 is provided, and the angle as a chute is secured by the restricting member 22a. By folding the standby section 22, the entire length of the container holder 21 can be shortened and compact storage is possible.
[0035]
Further, as shown in the plan view (a) of the container holder 21 showing the sensor arrangement example in FIG. 9, a detection member 32 for detecting the container A at the rear end position in the drawing direction D of the container A set in the holding portion 21a. Place. As shown in the side view of the operation of the container holder 21 in FIG. 9B, the detection member 32 is provided in the standby unit 22 so that the empty container B1 does not interfere when sliding from the standby unit 22 into the holding unit 21a. Configured below the step.
[0036]
By arranging the detection member 32 as described above, the empty container B1 can smoothly enter the holding portion 21a without being caught by the detection member 32, and the empty container B2 is set in the holding portion 21a. In this state, it can be detected by the detection member 32. Further, the empty container B2 is stably positioned by the step of the standby section 22.
[0037]
Therefore, by stopping the sorting conveyor 8 in conjunction with the detection of the full container A by the detecting member 32, if the container A is pulled out from the set position by being pulled out to the side D, even if it is pulled out from the end of the sorting conveyor 8, Can prevent the crop from spilling. Further, by controlling the operation of the sorting conveyor 8 in correspondence with the setting of the container A with respect to the holding unit 21a via the detection member 32, it is possible to cope with the interval between container A exchanges without any special operation by an operator. The operation of the selected conveyer 8 becomes possible.
[0038]
Next, as shown in a perspective view showing a configuration example of the container sensor of FIG. 10, a plan view (a) and an enlarged side view (b) of the mounted state of the container sensor of FIG. The contact body 42 having a curved surface on the outer peripheral surface is operated by contacting the lower surface of the container, and the presence or absence of the container is detected based on the operation. In a specific example shown in the figure, a spring 43 is connected to one end of a contact body 42 formed in an ellipsoid, and a bracket 44 is provided at the other end. The bracket 44 is pivotally supported in a vertically rotatable manner. And the like. The elliptical contact body 42 of the container sensor 41 is attached so that the center line in the longitudinal direction of the contact body 42 is orthogonal to the drawing direction D of the container A and is in contact with the lower surface of the container. And a signal is sent out by the displacement converter 45. Therefore, since the container comes into contact with the curved surface on the outer periphery of the contact body 42, and by supporting the contact body 42 rotatably in the container moving direction, the presence or absence of the container can be accurately detected even when the container moves, and It is also unlikely that the container sensor will be damaged by being dragged by the moving container.
[0039]
The container sensor 41 is configured such that even if the container A set at a predetermined position moves back and forth, left and right, the force acting on the ellipsoid 42 and the like is reduced, and even if the container A is pulled out and then returned again, the container A is caught. And the container A can be reset.
