Description

[Detailed Description of the Invention] The present invention relates to a foliage processing device in a harvester used for harvesting root vegetables such as onions.

As is well known, a harvesting machine for harvesting root vegetables such as onions uses a digging device to pick up such crops in the field, and then uses a stem and leaf cutting device to cut off the stems and leaves that are unnecessary for harvesting. They are cut and separated, and either lined up on the ground using a conveyor at the rear or stored in containers.

In such a harvester, a conventional foliage cutting device a has the configuration shown in FIG.

That is, a plurality of pairs of smooth rollers b and spiral rollers c are configured, which rotate inwardly to each other in the winding direction, and while the harvested product d is transferred in the direction of the feeding conveyor, the smooth rollers b and spiral rollers The stems and leaves e are rolled up between c and cut, and the stems and leaves e are allowed to fall to the lower side.

A transmission device and other devices f are installed below this foliage cutting device a, and above this a foliage cutting device a is installed.
There was a drawback that it accumulated.

In order to solve this drawback, a pedestal h is provided between the frames g of the harvester, and the leaves e are discharged to the outside of the frame g.

In this case, if the cut stems and leaves e have been sufficiently dried, they can be smoothly moved on the slope and discharged to the outside, but if it rains before harvesting, the leaves and leaves containing moisture can be removed. The sliding resistance becomes large, and a lot of leaves, leaves, e, soil, etc. accumulate on the pedestal h. For this reason, the accumulated stems and leaves were removed using sticks or hands. In particular, to remove the leaves directly by hand, place the leaf cutting device a directly above this pedestal h.
Therefore, there was a risk that hands, clothes, etc. could become caught between the rotating smooth roller B and spiral roller C, causing an accident.

On the other hand, if the leaves e accumulated on the pedestal h are left unattended, the accumulated leaves e may wrap around the rollers b and c, causing a decrease in cutting capacity or causing a malfunction. Something happened.

The present invention was developed to solve these problems, and is configured to smoothly discharge the cut stems and leaves of the crop to the outside of the harvester.

The feature is that a processing tool that rotates in the left-right direction is provided on the upper surface of a substantially semicircular arc-shaped holder provided below the foliage cutting device.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a schematic diagram showing the entire harvesting machine.

First, the outline of this harvesting machine will be explained. As main devices, a digging device 1, a foliage cutting device 2, a lateral conveyor 3, and a crawler traveling device 4 of well-known configuration are provided on the machine body. The digging device 1 is located at the front end of the machine, the foliage cutting device 2 is located at the center, and the lateral conveyor 3 is located at the rear end. It is arranged below the cutting device 2.

Note that this lateral conveyor 3 is not necessarily a necessary configuration, and a harvester may be configured with the necessary various devices by appropriately changing the design.

For example, it is possible to install removable containers for storing harvested products. Although not shown in the drawings, the engine and each transmission mechanism that serve as the motive force for driving each of the above-mentioned devices are disposed at the rear of the digging device 1 and below the foliage cutting device 2.

The digging device 1 has a digging tool 6 installed at the front end for digging up the harvested material, and a picking conveyor 7 is installed behind the digging tool 6 with a slight upward inclination toward the rear. As is well known, the picking up conveyor 7 is a shelf-like structure in which sticks, etc. that support the harvested products are arranged at optimal intervals, and the soil etc. attached to the harvested products is forced onto the lifting conveyor 8 while falling. to be transferred. The lifting conveyor 8 is installed in an upright manner at the rear of the picking conveyor 7, and is used to transfer the harvested products to the foliage cutting device 2 so as not to damage them.

Next, the foliage cutting device 2 will be explained. Its purpose is to cut the foliage of the harvest into appropriate sizes.

The outline of this cutting device 2 is as shown in the second figure, and a pair of smooth rollers 9 and a spiral roller 10 are provided as a set in parallel to the traveling direction of the harvester, and a plurality of sets of rollers 9 and 10 are provided. Built-in. The smooth roller 9 and the spiral roller 10 are in contact with each other and rotate in the inward winding direction, and the pair of rollers 9 and 10 rotate in opposite directions. Around the outer periphery of the spiral roller 10, members 11 made of round bars or the like are spirally arranged at appropriate pitches. While the harvested product 12 is transferred to the rear part by this member 11 such as a spiral round bar, the stems and leaves 13 are cut. The side plates 14, 14 on the left and right sides of the foliage cutting device 2 are for preventing the harvested product 12 from falling laterally.

As described above, the cut leaves 13 fall to the lower side by the leaf cutting device 2, but in many cases, a transmission device and other devices 15 are disposed on the lower side. A foliage processing device 5 for discharging the foliage 13 is required.

The foliage processing device 5 according to the present invention is configured as shown in FIG. and other equipment 1
In order to prevent the foliage 13 from falling onto the foliage cutting device 5, a pedestal 16 having a width larger than the various devices 15 is provided below the foliage cutting device 2 via a frame 17 of a harvester or the like. This pedestal 16 has an inclined surface so that the leaves 13 can be discharged to the left and right with respect to the direction of movement of the harvester. A processing tool 18 is provided to rotate the processing tool 18.

This processing tool 18 is used to remove the stems and leaves 1 accumulated on the pedestal 16.
3 to the left and right, and its shape is triangular in cross section in the illustration, but it can be configured to be rectangular, square, or any other shape optimal for discharging the stems and leaves 13. Further, arm rods 19, 19 are attached to both ends of the processing tool 18, and the lower ends of the arm rods 19 are attached to metal fittings 21 provided at the center of support rods 20, 20 fixed to the side surfaces of the pedestal 16 with bolts 22. It is pivoted so that it can rotate.

Note that by interposing a compression spring 23 between the bolt 22 and the arm rod 19, it is possible to prevent the processing tool 18 from shifting in the lateral direction due to vibrations of the harvester or the like.

As a mechanism for rotating the processing tool 18 left and right, a metal fitting 25 is attached to a member 24 fixed to the frame 17.
is fixed, a lever 26 is rotatably attached to this with a pin or the like 27, a connecting rod 28 is connected between the lever 26 and the arm rod 19 with a pin or the like 29,
A manual mechanism is constructed in which the processing tool 18 is rotated by moving the lever 26 left and right with the operator's hand. However, although not shown in the drawings, it is possible to change this to a manual type, provide a cam clutch to an electric motor, hydraulic motor, etc. as a power source, connect the cam clutch to the arm rod 19, and rotate the processing tool 18 left and right. Mechanisms are also possible.

In summary, the foliage processing device 5 in the harvester of the present invention cuts the foliage 13 on the pedestal 16 provided on the lower side of the foliage cutting device 2 which cuts the foliage 13 of the harvested product 12 by moving the processing tool 18 from side to side. By rotating it, it can be forcibly discharged to the outside of the harvester, so even leaves and leaves that contain moisture and have high slip resistance do not accumulate on the holder 16, and can be discharged by directly inserting a stick or hand into the harvester. Since there is no need to do this, there are advantages such as extremely safe harvesting operations.
