Description

The present invention relates to a root vegetable harvester that collects crops from a field and stores them in a storage member such as a flexible container bag.

Conventionally, there is a root vegetable harvester that uses a pulling and conveying device to pull and convey root vegetables from a field, and then stores the root vegetables in flexible container bags attached to the end of the conveying path of a sorting and conveying device (see, for example, Patent Document 1).

JP 2011-115069 A

However, because the flexi-con bags filled with root vegetables are lowered into the field toward the rear of the machine, when the machine is rotated to harvest crops in adjacent rows, the flexi-con bags lowered into the field are located immediately to the side of the moving machine. If the flexi-con bags tilt or the machine meanders slightly, there is a risk that the flexi-con bags may come into contact with the machine and rupture, scattering the root vegetables across the field and preventing proper harvesting.

The present invention was made in consideration of the above, and aims to provide a root vegetable harvester that prevents the machine body from coming into contact with storage components such as flexible container bags that have been lowered into the field.

The invention described in claim 1 provides an extracting and conveying device (17) on one of the left and right sides of the machine body, a loading platform (26) on which flexible container bags (22) are placed on the other left and right side of the machine body, and a sorting and conveying device (21) for conveying harvested crops from the extracting and conveying device (17) to the flexible container bags (22),

We will explain a carrot harvester, a type of root vegetable harvester, as an example of an embodiment of the present invention. In the following, references to front, back, left, and right are made based on the forward direction of the machine body.

<Overall structure>
The carrot harvester is composed of a traveling section A that drives the machine, a control section B on which the operator rides, a harvesting section C that pulls out carrots from the field on one side of the machine body and transports them to the upper rear of the machine body, a stem and leaf cutting section that takes over the carrots from the harvesting section C and transports them to the rear of the machine body while cutting the stems and leaves, a sorting and transporting section D that receives carrots that fall from the stem and leaf cutting section and processes the stems and leaves remaining on the carrots in a remaining leaf processing section, a sorting and transporting section D that takes over the carrots from the remaining leaf processing section and transports them from one side of the machine body to the other side, where an assistant operator sorts the carrots as they are transported, and a storage section E that stores storage materials for the carrots discharged from the sorting and transporting section D.

<Running section A>
Left and right crawlers 6L, 6R are configured by wrapping left and right belts 5, 5 around left and right drive sprockets 2, 2 on the front side of the machine body and left and right driven wheels 3, 3 on the rear side of the machine body below the machine frame 1, and a plurality of rollers 4 attached between the left and right drive sprockets 2, 2 and the left and right driven wheels 3, 3. The left and right drive sprockets 2, 2 of the left and right crawlers 6L, 6R are attached to left and right drive shafts extending on both the left and right sides from a transmission case to which engine power is transmitted, and the left and right crawlers 6L, 6R are attached to the machine frame 1 with a certain left-right gap between them.

<Control Unit B>
A control frame 7 is attached to the upper right side of the machine frame 1, and a control seat 8 is attached to the control frame 7, and a control panel 9 is attached to the front of the machine. A speed change lever 10 for switching the forward/reverse movement and traveling speed of the machine is attached to the control panel 9, and a lift control lever 11 for turning the machine left and right and for controlling the working height of the harvesting section C is also attached.

Furthermore, a radiator cover 12 that protects the radiator (not shown) that cools the engine and takes in cooling air is detachably attached to the other left or right side of the aircraft (right side of the aircraft) of the control unit frame 7, forming control unit B.

With the above configuration, by providing control members that can perform multiple operations with a single lever, such as the gear shift control lever 10 and the lift control lever 11, the aircraft becomes easier to control, thereby reducing the workload of the pilot.

<Harvesting Section C>
Left and right driven pulleys 14a, 14a are rotatably mounted on the front sides of the left and right pulling frames 13, 13, and left and right drive pulleys 14b, 14b are mounted on the rear sides of the machine. Left and right clamping conveyor belts 15, 15 for pulling carrots and transporting them to the rear of the machine are wound around the left and right driven pulleys 14a, 14a and the left and right drive pulleys 14b, 14b. The left and right clamping conveyor belts 15, 15 are tensioned by a plurality of tension rollers 16, and the inner sides of the left and right clamping conveyor belts 15, 15 are pressed against each other to form a carrot pulling and transport path (pulling and transport passage) R. A rotating frame is mounted above the machine frame 1 so as to be vertically rotatable about left and right horizontal axes as pivot points. A transmission case for transmitting driving force to the left and right drive pulleys 14b, 14b is mounted at the rear end of the rotating frame so as to be vertically rotatable about the pivot point. The machine frame 1 and the rotary frame are connected by a lifting cylinder, and the lifting cylinder is attached so as to be operable by the control section B, thereby forming a drawing and conveying device 17.

Also provided in front of the pulling-out and conveying device 17 is a vertical lifting device 18 that lifts the stems and leaves of the carrots, a horizontal lifting device 19 that scoops up the stems and leaves lifted by the vertical lifting device 18, a weed-separating rod 20 that is attached to the front of the horizontal lifting device 19, a rotatable gauge wheel that prevents the pulling-out and conveying device 17 from descending too far, and a left-right vibrating soiler S that vibrates back and forth using the driving force of the engine to loosen the soil on the left and right of the carrots buried in the soil.

A tail-cutting device that cuts off the roots of carrots being transported by the pulling and conveying device 17 is installed below the pulling and conveying path R, forming the harvesting section C.

With the above configuration, by providing a horizontal pulling device 19 with a grass-dividing rod 20 on the front of the machine body and a vertical pulling device 18, harvesting work can be performed while raking up the stems and leaves of carrots that have fallen in the field. This improves visibility of the carrots to be harvested, making it easier to adjust the pulling position, and reduces the amount of crop left behind, improving work efficiency.

In addition, it prevents carrots from coming into contact with the left-right vibrating soy machine S and other devices, thereby improving the commercial value of the carrots.

The machine frame 1 and a rotating frame that can rotate up and down around left and right horizontal axes are connected by a lifting cylinder, and the lifting cylinder is extended and retracted by operating the lifting control lever 11 on the control unit B. This allows the vertical height of the entire harvesting unit C to be adjusted by operating the lifting control lever 11, so the position of the starting end of the harvesting unit C for pulling and conveying can be adjusted vertically and to match the appropriate pulling height for carrots growing in the field. This prevents carrots from being left behind, improving work efficiency.

In addition, if the harvesting section C is raised when turning, the lower end of the harvesting section C is less likely to come into contact with the field, allowing for smoother turning operations and improving work efficiency.

<Sorting and Conveying Section D>
The sorting and conveying device 21 for sorting work in the sorting and conveying section D is arranged from the rear below the pulling and conveying device 17 in the harvesting section C toward the storage section E, where the flexible container bags 22, which are storage members for storing carrots, are located, and is composed of a chain conveyor with bars spaced at regular intervals that rotates with the driving force from the engine. Carrots conveyed by the pulling and conveying device 17 with their stems and leaves clamped, have their lower ends (slightly above the carrot head) cut in the stem and leaf cutting section, causing the carrots to fall downward. The remaining leaf processing section receives the fallen carrots, processes the stems and leaves remaining on the carrots, and conveys them to the sorting and conveying section D. The sorting and conveying device 21 in the sorting and conveying section D then conveys the carrots from their left ends to the right (storage section E).

The sorting and conveying device 21 is also composed of a horizontal conveyor 21a that is installed horizontally on the right side of the machine body from the rear below the extraction and conveying device 17 in the harvesting section C, and a movable conveyor 21b that takes over the harvested crops from the right end of the horizontal conveyor 21a and conveys them diagonally upward and to the right to the storage section E.

The movable transport conveyor 21b has its left end, which takes over harvested crops from the right end of the horizontal transport conveyor 21a, supported rotatably on a pivot shaft. The right end on the storage section E side moves up and down by the extension and contraction of the vertical movement electric cylinder 21c, allowing the inclination angle to be changed.

An auxiliary work seat 23 is provided at the rear of the movable transport conveyor 21b, and a worker seated on the auxiliary work seat 23 removes non-marketable carrots (small or irregularly shaped carrots) from the carrots being transported by the movable transport conveyor 21b, and sends only carrots with appropriate market value to storage section E.

In addition, the worker seated on the auxiliary work seat 23 operates the foot-operated lift switch and processing switch to extend and retract the vertical movement electric cylinder 21c, thereby moving the right end of the movable transfer conveyor 21b up and down.

<Storage section E>
The storage section E is located to the right of the sorting and conveying device 21 and is composed of a hanging hanger 25 that moves up and down and left and right by an operating arm 24 provided at the right end of the movable conveying conveyor 21b of the sorting and conveying device 21, and a loading platform 26 on which the flexi-bag 22 suspended from the hanging hanger 25 is placed.

The movable transport conveyor 21b extends diagonally upward from the base at the left end to the upper right end. It rotates using driving force from the engine, transporting carrots diagonally upward and releasing them downward from the top end. The base of the movable transport conveyor 21b is pivotally mounted on a pivot shaft, and the piston tip of an electric vertical movement cylinder 21c, whose base is pivotally supported on the machine frame 1, is connected to its midpoint.

That is, while the operator seated on the auxiliary work seat 23 presses the up switch, the vertical movement electric cylinder 21c extends and rotates around the pivot axis to raise the movable transfer conveyor 21b; while the operator presses the down switch, the vertical movement electric cylinder 21c retracts and rotates around the pivot axis to lower the movable transfer conveyor 21b. Furthermore, when the operator descends into the field and operates the cross-directional control lever 27 located on the right end of the control panel 9 (described below) to the right while facing the rear of the machine, the vertical movement electric cylinder 21c extends and rotates around the pivot axis to raise the movable transfer conveyor 21b; when the operator operates the cross-directional control lever 27 to the left, the vertical movement electric cylinder 21c retracts and rotates around the pivot axis to lower the movable transfer conveyor 21b.

The hanging hanger 25 moves up and down and left and right using an actuating arm 24 attached to the right end of the movable transport conveyor 21b.

The operating arm 24 is composed of a base arm 24a whose base is pivoted to the right end of the movable transport conveyor 21b so that it can rotate counterclockwise when viewed from the rear but stops rotating clockwise at a predetermined position, and whose tip extends toward the upper right outside of the machine body; a rotating arm 24b pivoted to the tip of the base arm 24a so that it can rotate freely; and an electric rotating cylinder 24c disposed between the base arm 24a and the rotating arm 24b as a rotation actuator.

The hanging hanger 25 is attached to the tip of the rotating arm 24b. Above the mounting base 26, the four hooks 25a of the hanging hanger 25 are hooked onto the locking holes on the upper edge of the flexible container bag 22, thereby hanging and supporting the flexible container bag 22.

A cross-directional control lever 27 is provided on the right end of the control panel 9. When the operator descends into the field and faces the rear of the machine, operating the lever to the right extends the vertical movement electric cylinder 21c, causing the movable transport conveyor 21b to rotate around the pivot axis and rise; operating the lever to the left causes the vertical movement electric cylinder 21c to retract, causing the movable transport conveyor 21b to rotate around the pivot axis and lower; operating the lever toward the rear of the machine extends the rotating electric cylinder 24c, causing the rotating arm 24b to rotate around the pivot axis and open outward to the right; operating the lever toward the front of the machine causes the rotating electric cylinder 24c to retract, causing the rotating arm 24b to rotate around the pivot axis and close inside the machine to the left.

When operating this cross-directional control lever 27, if the movable transport conveyor 21b is not in its highest position, operating the cross-directional control lever 27 toward the rear of the machine will not activate the electric rotating cylinder 24c, and the rotating arm 24b will not rotate around the pivot shaft and open outward to the right. In other words, only when the movable transport conveyor 21b is in its highest position can the cross-directional control lever 27 be operated toward the rear of the machine to activate the electric rotating cylinder 24c, causing the rotating arm 24b to rotate around the pivot shaft and open outward to the right.

In addition, a load sensor 28 is provided on the platform 26, and only when the flexible container bag 22 hanging from the hanging hanger 25 is lifted and the bottom of the flexible container bag 22 separates from the platform 26 (only when the load sensor 28 no longer detects the flexible container bag 22), can the cross-directional operating lever 27 be operated toward the rear of the machine to activate the rotating electric cylinder 24c, causing the rotating arm 24b to rotate around the pivot shaft and open outward to the right.

In addition, a photosensor 29 is provided at the right outer end of the platform 26 to detect the presence of an object above. When the flexible container bag 22 hanging from the hanging hanger 25 is lifted and the rotating arm 24b rotates around the pivot shaft due to the operation of the rotating electric cylinder 24c, opening to the right outer side and moving to the right outer side of the machine body, if the photosensor 29 does not detect that the flexible container bag 22 is not above the right outer end of the platform 26 (i.e., the flexible container bag 22 has moved to the right outer side of the right outer end of the platform 26), even if the cross-directional control lever 27 is operated to the left to rotate the movable transport conveyor 21b around the pivot shaft and lower it, the vertical movement electric cylinder 21c will not operate and the movable transport conveyor 21b will not move downward. This prevents the flexible container bag 22 from accidentally coming into contact with the right outer end of the platform 26 when lowering the flexible container bag 22 hanging from the hanging hanger 25 into the field.

<Carrot harvesting work>
First, as shown in FIG. 4, the cross-directional operating lever 27 is operated to move the movable transfer conveyor 21b to its lowest position with the rotating arm 24b closed inside the left machine body.

The flexible container bag 22 is hung by hooking the hooks 25a of the hanging hanger 25 into the locking holes at the upper edge of the flexible container bag 22, with the bottom of the flexible container bag 22 supported on the mounting base 26.

The operator seated in the driver's seat 8 then advances the carrot harvester, aligning the front end of the extraction and conveying path R of the extraction and conveying device 17 of the harvesting section C with the carrot rows in the field, then operates the lifting operation lever 11 to lower the harvesting section C, engages the digging clutch, and drives each section to move forward. The carrot stems and leaves are then scraped up by the weeding rod 20, vertical pulling device 18, and horizontal pulling device 19, and are clamped in the extraction and conveying path R of the extraction and conveying device 17. The left and right vibrating soiler S loosens the soil to the sides and below the carrots, and the carrots are then clamped and pulled out by the extraction and conveying device 17 and conveyed rearward and upward.

Then, the carrots, whose stems and leaves are clamped and transported by the pulling and transporting device 17, have their lower ends (slightly above the carrot's top) cut in the stem and leaf cutting section, and the carrots fall downward. The remaining leaf processing section receives the carrots, processes the remaining stems and leaves, and transports them to the sorting and transporting section D. The carrots are then transported from the left end to the right (storage section E) by the movable transport conveyor 21b of the sorting and transporting section D.

Then, a worker seated in the auxiliary work seat 23 at the rear of the movable transport conveyor 21b removes non-marketable carrots (small or irregularly shaped carrots) from the carrots being transported by the movable transport conveyor 21b, and only marketable carrots are sent to the storage section E.

Carrots sent to the right end by the movable transport conveyor 21b fall into and are stored in the flexible container bags 22 hanging from the hooks 25a of the hanging hangers 25 at the right end of the movable transport conveyor 21b.

As the amount of carrots stored in the flexible container bag 22 increases, the worker seated on the auxiliary work seat 23 presses the lift switch to extend the vertical movement electric cylinder 21c, causing the movable transport conveyor 21b to rotate around its pivot axis and gradually rise.

Then, as shown in Figure 5, the movable transport conveyor 21b is rotated around the pivot shaft and raised until the flexible container bag 22 is filled with carrots, and then the operator stops driving the machine and stops it.

The operator seated in the auxiliary work seat 23 leaves the auxiliary work seat 23, descends into the field, stands near the right end of the control panel 9, and operates the cross-directional control lever 27 while facing the rear of the machine body.

First, the cross-directional control lever 27 is moved to the right to extend the vertical movement electric cylinder 21c, raising the movable transfer conveyor 21b to its highest position and lifting the flexible container bag 22 above the platform 26 as shown in Figure 6.

Then, the cross-directional operating lever 27 is operated toward the rear of the machine, as shown in Figure 7, to extend the rotating electric cylinder 24c, causing the rotating arm 24b to rotate around the pivot shaft and open outward to the right, and the flexible container bag 22 is moved to the outer right side of the loading platform 26.

Then, the cross-directional control lever 27 is operated to the left to retract the vertical movement electric cylinder 21c and lower the movable transport conveyor 21b to its lowest position, thereby lowering the flexible container bag 22 into the field as shown in Figure 8.

Then, the hooks 25a of the hanging hanger 25 are released from the locking holes on the upper edge of the flexible container bag 22, and the cross-directional operating lever 27 is operated to return to the state shown in Figure 4. The hooks 25a of the hanging hanger 25 are hooked onto the locking holes on the upper edge of the empty flexible container bag 22, and the flexible container bag 22 is suspended so that the bottom of the flexible container bag 22 is supported on the platform 26. Then, the operator sits on the auxiliary work seat 23. Then, the various components are driven to move the machine forward and resume harvesting work.

After the harvesting work is completed, as shown in Figure 9, the cross-directional operating lever 27 is operated to raise the movable transport conveyor 21b to its highest position, close the pivot arm 24b, and rotate the operating arm 24 around the pivot at the base of the base arm 24a and into the machine body to store it in place. The platform 26 is also rotated upward and inward around the pivot at the base to store it in place. When in the stored state, the width of the machine body is reduced, making it easier to drive on the road, load and unload onto a truck, or store in a barn, etc.

In summary, the hanging hanger 25 moves up and down and left and right using the operating arm 24 attached to the right end of the movable transport conveyor 21b. Therefore, the flexible container bag 22 placed on the platform 26 while suspended from the hanging hanger 25 can be lifted above the platform 26 by the operating arm 24 and lowered into the field at a position to the right of the platform 26. Even if the flexible container bag 22 lowered into the field tilts or the machine meanders slightly, the flexible container bag 22 can be prevented from coming into contact with the machine, ensuring smooth and appropriate harvesting operations.

<Other embodiments>
(1) FIG. 10 shows a second embodiment, which shows another example of the operating arm 24.

That is, the operating arm 24, whose base is pivotally supported on the movable transport conveyor 21b, is composed of a right operating link 30 and an electric cylinder 31, whose base is pivotally supported on the movable transport conveyor 21b, and an upper link 32, which is connected and pivoted to the upper ends of the right operating link 30 and the electric cylinder 31.

A hanging hanger 25 is attached to the tip of the upper link 32.

Therefore, when the electric cylinder 31 is operated, the flexible container bag 22 suspended from the hanging hanger 25 can be lowered into the field at a position to the right and outside of the loading platform 26.

(2) Figure 11 shows the third embodiment, illustrating another example of the actuating arm 24.

That is, the operating arm 24 is composed of a cylindrical body 33 fixed to the movable transfer conveyor 21b and an operating rod 34 that moves left and right within the cylindrical body 33. The base of the operating rod 34, which is inserted into the cylindrical body 33, is formed with a helical thread 34a, and when driven by the electric motor 35, a rotating ring 36 with an engaging protrusion that engages with the helical thread 34a rotates, causing the operating rod 34 to move left and right on the machine body.

A hanging hanger 25 is attached to the right end of the operating rod 34.

Therefore, when the electric motor 35 is operated, the flexible container bag 22 suspended from the hanging hanger 25 attached to the right end of the operating rod 34 of the operating arm 24 can be lowered into the field at a position to the right of the outer side of the loading platform 26.

(3) Figure 12 shows the fourth embodiment, illustrating another example of the actuating arm 24.

That is, the operating arm 24 is composed of an electric cylinder 37 fixed to the movable transfer conveyor 21b and a link 38 attached to the tip of the electric cylinder 37. The hanging hanger 25 is attached to the tip of the link 38.

Therefore, when the electric cylinder 37 is extended, the flexible container bag 22 suspended from the hanging hanger 25 can be lowered into the field at a position to the right and outside of the loading platform 26.
