Further, the digging traveling direction referred to in the present invention is a direction in which the vehicle travels to dig up long root vegetables, and even if it is a traveling body or a self-propelled long root vegetable harvesting device, it moves backward. It may be a direction.

Further, the transport direction referred to in the present invention is a direction in which the transport guide unit transports the dug long root vegetables to the harvesting work conveyor.

Hereinafter, a long root vegetable harvesting apparatus (hereinafter referred to as a harvesting apparatus) according to an embodiment according to the present invention will be described with reference to FIGS. 1 to 5.

In the following description, the digging traveling direction is the front, and the side opposite to the digging traveling direction is the rear. In addition, the left and right sides are based on the digging running direction (traveling direction) (therefore, the left and right sides are reversed on the paper shown in FIG. 1). In addition, long root vegetables will be described as long potatoes. Moreover, each embodiment described below does not limit the present invention.

The harvesting device (long root vegetable harvesting device) 1 is towed by a traveling body (not shown) such as a tractor to move forward and perform harvesting work, and the digging blade 2 arranged on the left side of the front part A transport conveyor (conveyor) 3 that is pivotally supported at the rear end of the digging blade 2, and a harvesting work conveyor that is located at the rear end of the transport conveyor 3 and is located on the right side. 4 and a frame (aircraft) 6 having a connecting portion 5 connected to the above-mentioned traveling body, a work table 60 on which the worker 100 sits, a seat 61 and wheels 62 arranged on the left side for the worker 100 to sit on. And have. Further, the frame 6 is provided with a hydraulic cylinder 63 and a link mechanism (not designated) as a mechanism for rotating the digging blade 2 about the rotation shaft 64.

As shown in FIGS. 2 and 3, since the digging blade 2 and the conveyor 3 are connected in a pivotally supported manner, the digging blade 2 rotates as a rotation axis in the left-right direction of the machine body. The conveyor 3 is bent when it rotates about the axis of the shaft 64. Further, the end of the conveyor 3 is pivotally supported by one end of the flat bar 65, and the other end of the flat bar 65 is pivotally supported by the frame 6 at the flat bar rotation fulcrum 66. What is common to FIG. 2 (a) and FIG. 2 (b), which is an enlarged view of part A, is an object of a leader line indicated by a name and a number such as "2 digging blade". Is the state when the digging blade 2 is invading the soil, and the target of the leader line indicated by only the number such as "2" is pulled out to the above-ground part. It is the state when it is.

The digging blade 2 has a plate shape with a pointed front end, and is arranged so that the wide surface faces upward. The front end is inserted so as to be located below the long potato in the soil. By advancing the traveling body in a state where the rear end of the conveyor 3 is inclined from the position of the front end to near the ground, the long potatoes are dug up so as to be sent backward while lifting the soil. ing.

By adopting such a pivotal structure at three points of the digging blade 2, the conveyor 3, the flat bar 65, and the frame 6, the digging blade 2 is first inserted into the soil as shown in FIG. Only the cutting edge can be inserted at a steep angle. Initially, the conveyor 3 is inclined so that the front end is on the top, but when the digging blade 2 rotates while invading the soil, the digging blade 2 gradually falls asleep and is conveyed. The conveyor 3 is also in line with the digging blade 2 and is inclined so that the front end is downward, so that the harvesting operation is in a steady state.

FIG. 4 is a diagram showing a steady state of the harvesting operation. The operation of the digging blade 2 to dig up the long potato is performed by the advance of the digging blade 2 as the traveling body advances, and the position of the digging blade 2 in the forward direction changes during traveling, so that the traveling body advances. The accompanying forward movement of the digging blade 2 is an operation of lifting the long potatoes together with the soil and sending them backwards, and the speed of sending the long potatoes backwards is the same as the forward speed of the traveling body.

The long potatoes dug by the digging blade 2 are upward in the longitudinal direction (state before digging), and in this upward state, they are sent to the rear conveyor 3 while being supported by the soil to be dug at the same time. ..

The transport conveyor 3 is located in the ground during the harvesting of the long potatoes, and transports the long potatoes dug by the digging blade 2 backward while lifting the soil together with the soil on the transport surface by its own transport force. The long potatoes to be conveyed by the transfer conveyor 3 are upward in the longitudinal direction (state before digging), and in this upward state, they are conveyed backward while being supported by the soil to be conveyed at the same time. The worker 100 located in the seat 61 replaces the transported long potatoes on the harvesting work conveyor 4 so as to be in a sideways state.

Previously, the inventor of the present invention proposed a structure in which the transfer from the transport conveyor to the harvesting work conveyor was automatically performed, but it was found that the long potatoes were damaged. This time, this remounting was done manually, and a structure was adopted in which the digging blade 2 and the conveyor 3 were bent. The inventor of the present invention thoroughly analyzed the factors that damage the dioscorea opposita and optimized the division of automatic work and manual work.

Since the transport of the long potatoes by the transport conveyor 3 is performed at the same time as the traveling body advances, the transport speed of the transport conveyor 3 is set from the speed at which the long potatoes are fed backward by the digging blade 2 (advance speed of the traveling body). Is also preferable.

When the harvesting work progresses and the harvesting device 1 approaches the end of the shore, it becomes necessary to pull up the digging blade 2 from the soil at one end. FIG. 5 is a diagram showing a state when the digging blade 2 is pulled out from the soil. By adopting a pivotal structure at three points of the digging blade 2, the conveyor 3, the flat bar 65, and the frame 6 described with reference to FIG. 2, the digging blade 2 stands up as shown in FIG. Even if it rotates to, the conveyor 3 does not stand up together and eventually tilts so that the front end faces upward. As described above, in the conventional long root vegetable harvesting apparatus, as shown in FIG. 7, the transport conveyor also stands upright as the digging blade is pulled up, so that the long potatoes are spilled and damaged. However, in the present invention, the long potatoes do not spill, and therefore, they do not break or get hurt.

The harvesting work conveyor 4 performs various harvesting operations such as sorting of long potatoes transported on the harvesting work conveyor 4, and the transfer direction is the same as the transfer direction of the transfer conveyor 3 at the rear end of the transfer conveyor 3. It is located on the right side. However, the left-right arrangement of the transport conveyor 3, the harvesting work conveyor 4, and the seat 61 in relation to the frame 6 may be reversed. That is, the digging blade 2 may be arranged on the right side of the frontmost portion, the harvesting work conveyor 4 may be arranged on the left side at the rear end of the transport conveyor 3, and the seat 61 may be arranged on the right side.

The inclined surface 41 is arranged so that the transferred long potatoes are placed and conveyed so that the longitudinal direction thereof is along the left-right direction (the width direction of the harvesting work conveyor 4).

The flat surface 42 is set at a height position at which the worker 100 can easily perform work such as sorting while standing, so that the burden of the worker's sorting work can be reduced.

On the workbench 60, storage boxes 200 corresponding to the grades of the selected long potatoes are placed, and the selected long potatoes are housed in the corresponding storage boxes 200, respectively.

The connecting portion 5 is supported in front of the frame 6 and includes a link mechanism that transmits the expansion / contraction movement of the hydraulic cylinder 63 as the rotational movement of the digging blade 2. The link mechanism allows the digging blade 2 to rotate on the rotation shaft. It is rotated around 64.

Here, it is effective to use the driving force from the traveling body as the power of the hydraulic cylinder 63, the transport conveyor 3, and the harvesting work conveyor 4, for example, via a necessary power transmission system (not shown). Means such as connecting to the PTO axis (not shown) of the traveling body or driving the drive motor (not shown) by the battery of the traveling body can be adopted.

According to the harvesting apparatus described above, the digging blade 2 is configured to rotate about the rotation axis in the left-right direction of the machine as a fulcrum, and the transport conveyor 3 folds as the digging blade 2 rotates. Since the structure is such that the digging blade 2 is pivotally supported by the digging blade 2 so as to bend, it is easy to insert only the cutting edge at a steep angle when inserting the digging blade 2 into the soil. At the same time, it is possible to prevent the long potatoes from spilling and being damaged when the digging blade 2 is pulled out from the soil and raised above the ground during the harvesting operation.

The present invention is not limited to the illustrated embodiment, and can be implemented with a configuration within a range that does not deviate from the contents described in the scope of claims for utility model registration.
