Embodiments for Carrying Out the Invention

[0022] While referring to the drawings, embodiments of the present invention will be described in detail.

[0023] The same applies hereinafter, but some components may not be shown in the drawings, or may be shown perspectively or omitted.

[0024] While explaining the operation of the chestnut harvesting work vehicle according to the embodiment of the present invention, the chestnut harvesting work vehicle operation control method of the invention related to the present invention, which is realized by a controller or the like, will also be explained.

[0025] Such a chestnut harvesting work vehicle is a chestnut harvesting work vehicle that harvests chestnuts while traveling, and is a specific example of the chestnut harvesting work vehicle according to the present invention.

[0026] (1) First, with reference mainly to FIG. 1, the configuration and operation of the chestnut harvesting work vehicle according to the embodiment of the present invention will be specifically described.

[0027] Here, FIG. 1 is a perspective view (one of them) of the chestnut harvesting work vehicle according to the embodiment of the present invention.

[0028] The chestnut storage unit 100 is a unit that stores chestnuts on the ground surface.

[0029] After the chestnut harvesting work is completed, the chestnuts collected and stored inside the basket can be easily taken out manually from the chestnut outlet where an openable basket lid or the like is attached.

[0030] The chestnut storage unit 100 includes a rotary basket-shaped member 110 in which a plurality of bars 111 having a predetermined bar elasticity are arranged cylindrically at a predetermined bar interval, and a plate member 120 provided below the rotary basket-shaped member 110, the upper surface of the plate being curved so as to follow the shape of the rotary basket-shaped member 110.

[0031] The chestnuts not covered with chestnut husks are successively collected by the chestnut storage part 100 so as not to be crushed, and the chestnut husks can be sorted on the spot, thus improving the working efficiency.

[0032] The longitudinal directions of the plurality of bars 111 coincide with the direction of the rotation axis of the rotary basket-shaped member 110. Along with the rotation of the rotary basket-shaped member 110, the chestnuts pushed into the interior of the basket of the rotary basket-shaped member 110 from the gaps between the plurality of bars 111 are stored inside the basket.

[0033] In this way, in the configuration where the chestnuts are separated from the chestnut husks and collected, the chestnuts are stored inside the rotary basket-shaped member 110, which is an aggregate of slender bars 111 having high flexibility, such as the whipping wire of a whipping device.

[0034] The chestnuts are pushed into the interior of the basket from the gaps between the plurality of bars 111, and a predetermined bar elastic force and a predetermined bar interval are set so that the chestnuts and the chestnut husks covering the chestnuts are not pushed into the interior of the basket from the gaps between the plurality of bars 111.

[0035] Most of the chestnuts not covered with chestnut husks do not pass through the husk peeling part 200 as a so-called threshing mechanism, and thus are recovered with almost no damage.

[0036] The chestnut husks separated from the chestnuts may be caught by a sponge material attached to the bars 111 or an adhesive resin tape material.

[0037] The chestnuts may be sandwiched by the bars 111 such as the above-described wire rods or metal plates and directly sent to the chestnut container 1001 for temporarily storing the chestnuts.

[0038] It is desirable that, for example, an auger mechanism for directly transporting the chestnuts from the chestnut container 1001 to the truck is provided below the roller member 210.

[0039] The chestnut container 1001 is a box container or a flexible container such as a bag.

[0040] For example, as a preliminary empty container, a pre-use flexible container hook for hanging and storing a pre-use flexible container that does not contain chestnuts may be attached.

[0041] A post-use flexible container hook for firmly hanging the post-use flexible container containing chestnuts may be attached.

[0042] The post-use flexible container hook may be the same hook as the pre-use flexible container hook.

[0043] Note that the gap between the plurality of bars 111 and the plate member 120 may become narrower from the front side of the vehicle body toward the rear side of the vehicle body.

[0044] As the gap between the bar 111 of the rotary basket-like member 110 and the plate member 120 which is a member like a large claw gradually becomes narrower, an effect is expected that the chestnut husks are kneaded and peeled off.

[0045] (2) Next, with reference mainly to FIGS. 2 to 4, the configuration and operation of the chestnut harvesting work vehicle according to the embodiment of the present invention will be described more specifically.

[0046] Here, FIG. 2 is a perspective view (part two) of the chestnut harvesting work vehicle according to the embodiment of the present invention, FIG. 3 is a left side view of the chestnut harvesting work vehicle according to the embodiment of the present invention, and FIG. 4 is a schematic partial left side view of the chestnut harvesting work vehicle according to the embodiment of the present invention.

[0047] The chestnut storage unit 100 not only has a function of storing chestnuts on the ground surface, but also has a function of picking up chestnuts and chestnut husks on the ground surface and sending them rearward.

[0048] Before passing through the husk peeling section 200, the chestnut husks are peeled even in the gap between the bar 111 and the plate member 120, which not only improves work efficiency, but also most of the chestnuts not covered by the chestnut husks can pass through such a gap with little damage, and an improvement in the harvesting rate is also expected.

[0049] Due to the rotation of the rotary basket-shaped member 110, the chestnuts and chestnut husks that have entered the space between the plurality of bars 111 and the plate member 120 are picked up and sent rearward.

[0050] Since the chestnut husks are crushed and finely broken in the gradually narrowing gap described above, for example, the processing of the chestnut husks at the rear stage is easy, and it is difficult for the air passage to become clogged in the substantially L-shaped air passage unit through which the chestnut husks blown by the air separation unit 400 pass.

[0051] Such an air passage unit as a conveyance path for conveying defective chestnuts and chestnut husks may be provided with a foreign object extrusion lever mechanism or the like for eliminating air passage clogging.

[0052] A stopper member S for preventing the trailing rotation of the chestnuts and chestnut husks accompanying the rotation of the rotary basket-shaped member 110 is attached near the rear surface of the rotary basket-shaped member 110 so that the chestnuts and chestnut husks are separated from the rotary basket-shaped member 110 and sent rearward.

[0053] The chestnuts and chestnut husks are locked by a stopper member S having, for example, an I-shaped locking material and are reliably sent rearward, so that work efficiency is improved.

[0054] (3) Next, with reference mainly to FIGS. 1 to 3, 5, and 6, the configuration and operation of the chestnut harvesting work vehicle according to the embodiment of the present invention will be described in more detail.

[0055] Here, FIGS. 5 and 6 are perspective views (one and two) of the chestnut harvesting work vehicle according to another embodiment of the present invention.

[0056] The husk peeling unit 200 is a unit that peels the husk of chestnuts picked up by the chestnut storage unit 100 and sent rearward from the chestnuts. The husk peeling unit 200 has two roller members 210.

[0057] The roller member 210 is a roller like the so-called threshing roller of a rice huller.

[0058] The rotation axes of the two roller members 210 are parallel to each other. By rotating the two roller members 210 at different peripheral speeds, the husk of the chestnuts sandwiched in the gap between the two roller members 210 is peeled off from the chestnuts.

[0059] Among the two roller members 210, for example, the roller member 210 on the front side of the vehicle body is a roller member with a relatively large roller diameter, and the roller member 210 on the rear side of the vehicle body is a roller member with a relatively small roller diameter.

[0060] The size of the gap between the two roller members 210 is adjustable.

[0061] A pressure-sensitive sensor or the like for detecting the roller pressing pressure between the two roller members 210 is attached to the husk peeling unit 200, and it is desirable that the roller pressing pressure is automatically adjusted based on the detection result of the pressure-sensitive sensor.

[0062] The elevator unit 300 is a unit that lifts the husk of chestnuts picked up by the chestnut storage unit 100 and sent rearward from the chestnut storage unit 100 toward the husk peeling unit 200. The winnowing unit 400 is a unit that blows the husk of chestnuts peeled from the chestnuts by the husk peeling unit 200.

[0063] The winnowing unit 400 has a suction fan device 410.

[0064] The winnowing section 400 in front of or behind the husk removal section 200 sucks the husks of the shelled chestnuts below the husk removal section 200 by generating suction air or discharge air with a blower fan mechanism.

[0065] The fan blade 411 of the suction fan device 410 is a cutter blade.

[0066] The fan blade 411 is, for example, a blade like a lawn mower blade that can finely break the husks of chestnuts.

[0067] The husks of the thrown chestnuts are crushed by the fan blade 411 and discharged toward the rear side of the suction fan device 410.

[0068] As shown in FIGS. 5 and 6, the intake air from the intake slit window on the front side of the vehicle body is performed by the winnowing section 400 behind the husk removal section 200. By generating suction air, good chestnut fruits fall, but the husks of chestnuts mixed with defective chestnut fruits are sucked into the suction fan device 410 and crushed by the fan blade 411, and the crushed husks of chestnuts are stored in the downstream space or the like.
