Embodiments for Carrying Out the Invention

[0029] The embodiments of the present invention will be described in detail with reference to the drawings.

[0030] The same applies hereinafter, but some components may not be shown in the drawings, or may be shown perspectively or omitted.

[0031] 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.

[0032] 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 in the present invention.

[0033] (1) First, with reference mainly to FIGS. 1 to 3, the configuration and operation of the chestnut harvesting work vehicle according to the embodiment of the present invention will be specifically described.

[0034] Here, FIGS. 1 to 3 are perspective views (one to three) of the chestnut harvesting work vehicle according to the embodiment of the present invention.

[0035] The chestnut picking-up unit 100 is a unit for picking up chestnuts on the ground surface. The husk peeling unit 200 is a unit for peeling the husks of chestnuts covering the chestnut fruits picked up by the chestnut picking-up unit 100 from the chestnut fruits.

[0036] The husk peeling section 200, which is provided behind the elevator section 300 and serves as a so-called threshing mechanism, successively peels the husks of chestnuts that fall from the end of the elevator below the elevator section 300.

[0037] Since the husks of chestnuts are peeled off and separated from the chestnut fruits, the time until a container for storing chestnut fruits, such as the chestnut fruit container 1001, is filled is ensured to be sufficiently long.

[0038] The chestnut harvesting work vehicle as a chestnut harvesting machine has not only the chestnut lifting section 100 as a mechanism for collecting chestnuts lying on the ground, but also the husk peeling section 200 as a mechanism for peeling the husks of chestnuts. Since the husks of chestnuts can be sorted on the spot, the working efficiency is improved.

[0039] The elevator section 300 is a unit that lifts the chestnuts lifted by the chestnut lifting section 100 from the chestnut lifting section 100 toward the husk peeling section 200.

[0040] The elevator section 300 as an elevator mechanism for lifting chestnuts upward is provided behind the accumulation section 500.

[0041] A hydraulic cylinder mechanism for elevator movement in the vertical direction is provided to the elevator section 300, and by such elevator movement, the chestnut lifting section 100 and the accumulation section 500 are also moved in the vertical direction.

[0042] By lifting the chestnuts with the elevator section 300 and securing a winnowing space at a sufficient distance in the vertical direction, unnecessary peeled chestnut husks are surely blown off and selectively removed by the winnowing section 400.

[0043] The winnowing section 400 is a unit that blows off the chestnut husks peeled from the chestnut fruits by the husk peeling section 200.

[0044] The winnowing section 400 in front of the husk removal section 200 generates suction air or discharge air with a blower fan mechanism to successively blow the husks of the shelled chestnuts below the elevator section 300.

[0045] (2) Next, with reference mainly to FIGS. 4 to 10, 11, 12, 13, 14, 15(a) and 15(b), the configuration and operation of the chestnut harvesting work vehicle in the embodiment of the present invention will be described in more detail.

[0046] Here, FIGS. 4 to 10 are perspective views (from the fourth to the tenth) of the chestnut harvesting work vehicle in the embodiment of the present invention, FIG. 11 is a plan view of the chestnut harvesting work vehicle in the embodiment of the present invention, FIG. 12 is a front view of the chestnut harvesting work vehicle in the embodiment of the present invention, FIG. 13 is a left side view of the chestnut harvesting work vehicle in the embodiment of the present invention, FIG. 14 is a right side view of the chestnut harvesting work vehicle in the embodiment of the present invention, FIG. 15(a) is a schematic partial left side view of the chestnut harvesting work vehicle in the embodiment of the present invention, and FIG. 15(b) is a schematic partial left side view of another chestnut harvesting work vehicle in the embodiment of the present invention.

[0047] The chestnut lifting section 100 includes a rotating cylindrical member 110 in which a plurality of rod members 111 are arranged in a cylindrical shape at a predetermined rod member interval, and a plate member 120 provided below the rotating cylindrical member 110 whose upper surface of the plate is curved along the shape of the rotating cylindrical member 110. The longitudinal directions of the plurality of rod members 111 coincide with the direction of the rotation axis of the rotating cylindrical member 110. By the rotation of the rotating cylindrical member 110, the chestnuts that have entered the space between the plurality of rod members 111 and the plate member 120 are lifted.

[0048] In order to more reliably perform the chestnut lifting and collecting operation by the chestnut lifting section 100, a pressure-sensitive sensor for detecting the ground pressure or the like is attached to the rotating cylindrical member 110 as the rotating part, and it is desirable that the chestnut lifting section 100 be automatically made to follow the ground surface based on the detection result of the pressure-sensitive sensor.

[0049] The rotating cylindrical member 110 has a cylindrical body 112 and a plurality of rod members 111 as a plurality of rib members disposed on the outer surface of the cylindrical body 112.

[0050] The rod member 111 is, for example, a strip-shaped plate member whose both ends are bent at approximately 90 degrees and attached to the peripheries of both end faces of the rotating cylindrical member 110 by bolt fastening or the like. A window-shaped slit opening may be formed in a gap between the rod members 111 disposed at equal rod member intervals, through which chestnut husks and chestnut spines are sandwiched as the rotating cylindrical member 110 rotates. Such a window-shaped slit opening may not be formed, the gap between the rod members 111 may be blocked, or the gap between the rod members 111 may not exist at all.

[0051] The husk peeling part 200 has two roller members 210.

[0052] Since the chestnut spines are firmly sandwiched between two roller members 210 having different so-called threshing roller rotation ratios, the chestnut spines can be surely peeled from the chestnuts.

[0053] The rotation axes of the two roller members 210 are parallel to each other. When the two roller members 210 rotate at different peripheral speeds, the chestnut spines sandwiched in the gap between the two roller members 210 are peeled from the chestnuts.

[0054] By using spring biasing or the like, it is desirable that the pressure with which the two roller members 210 sandwich the chestnut spines is kept constant.

[0055] The position of the front end of the plate member 120 is in front of the vertical plane including the rotation axis of the rotating cylindrical member 110 and below the horizontal plane including the rotation axis of the rotating cylindrical member 110. The position of the rear end of the plate member 120 is behind the vertical plane including the rotation axis of the rotating cylindrical member 110 and below the horizontal plane including the rotation axis of the rotating cylindrical member 110.

[0056] The plate member 120 is a member like a large claw for scooping up chestnuts from the lower part of the rotating cylindrical member 110 toward the rear. Since the lower front tip of the plate member 120 is located in front of the rotation center of the rotating cylindrical member 110 and the upper rear tip of the plate member 120 is located below the rotation center of the rotating cylindrical member 110, when the chestnuts are scooped up, they are less likely to spill and are smoothly dropped onto the rear accumulation part 500.

[0057] The accumulation part 500 is a unit that conveys the chestnuts picked up by the chestnut picking-up part 100 toward the lower end of the elevator part 300. The accumulation part 500 has a conveying screw member 510 whose longitudinal direction is the left-right direction of the vehicle body.

[0058] By the rotational drive of the conveying screw member 510 provided in the accumulation part 500, the picked-up chestnuts are surely accumulated at a part of the lower end of the elevator part 300 as the next conveying mechanism.

[0059] Based on the position of the lower end of the elevator part 300, the screw direction on the left side of the vehicle body of the conveying screw member 510 is opposite to the screw direction on the right side of the vehicle body of the conveying screw member 510.

[0060] Since the left and right spiral directions of the conveying screw member 510 which is a spiral body are different from each other, almost no reverse flow of chestnuts occurs, and the picked-up chestnuts are surely accumulated.

[0061] In the vicinity of the lower end of the elevator part 300, a round bar is welded instead of the spiral body, and the chestnuts struck by such a round bar surely fall into the elevator entrance of the elevator part 300.

[0062] The first guide air duct part 610 is a unit extending rearward through which the husks of the chestnuts blown by the air separation part 400 pass.

[0063] The first guide air passage part 610 below the husk removal part 200 having a cover member is a unit for successively separating good chestnuts from bad chestnuts and chestnut husks one after another behind the blower fan of the air separation part 400.

[0064] The second guide air passage part 620 is a unit extending in the left - right direction of the vehicle body through which the chestnut husks that have passed through the first guide air passage part 610 pass.

[0065] The second guide air passage part 620 having an inclined cover member for conveying bad chestnuts and chestnut husks toward the right side of the vehicle body is provided behind the cover member of the first guide air passage part 610.

[0066] The third guide air passage part 630 is a unit extending forward through which the chestnut husks that have passed through the second guide air passage part 620 pass. The husk storage part 700 is a unit for storing the chestnut husks that have passed through the third guide air passage part 630.

[0067] A frame member on which the chestnut container 1001 for temporarily storing chestnuts is placed is provided below the cover member of the first guide air passage part 610, alongside the placement waste collection table near the husk storage part 700 on which a bag for collecting chestnut husks etc. is placed.

[0068] The operation control part 800 is a unit provided near the second guide air passage part 620.

[0069] The operation control part 800 above the cover member of the second guide air passage part 620 is an operation part having a joystick etc. for operation control.

[0070] Since the operation control part 800 is provided near the second guide air passage part 620, the operator can easily separate good chestnuts from bad chestnuts that are inadvertently mixed with them in the second guide air passage part 620 while performing manual operation of the operation control part 800 despite the air separation.

[0071] The floor surface of the first guide air passage part 610 is an upward inclined surface on which chestnut husks roll upward. The floor surface of the second guide air passage part 620 is a downward inclined surface on which chestnut husks roll downward.

[0072] The inclination angles of the upward inclined surface of the first guide air passage part 610 and the downward inclined surface of the second guide air passage part 620 are adjustable so that good chestnuts can be reliably separated from poor-quality chestnuts and chestnut husks by the air passing through the first guide air passage part 610 and the second guide air passage part 620, and it is desirable to achieve free separation level adjustment according to the situation.

[0073] The operator step part 900 is a unit provided behind the operation control part 800.

[0074] An operator standing on the step of the operator step part 900 provided near the central part on the rear side of the vehicle body can easily perform the manual operation of the operation control part 800.

[0075] Since the burden on the operator is greatly reduced by the implementation of the operator step part 900, a user-friendly specification that is less likely to cause work fatigue is realized.

[0076] Note that the gap between the plurality of rod members 111 and the plate member 120 may become narrower from the front side to the rear side of the vehicle body.

[0077] As shown in FIG. 15(b), since the chestnut husks are crushed and finely broken in such a narrow gap, the subsequent processing of the chestnut husks is easy, and air passage blockage is less likely to occur in the substantially L-shaped air passage unit composed of the first guide air passage part 610, the second guide air passage part 620, the third guide air passage part 630, etc. through which the chestnut husks blown by the air separation part 400 pass.

[0078] The power unit 1002 composed of an engine or a motor and a transmission case, etc., which supplies driving power and performs speed change, etc., is housed in the space near the elevator part 300 formed on the lower right side of the vehicle body.

[0079] The power pulley, power belt, power tension arm, etc., which transmit the driving power from the power unit 1002, are housed in the space formed in the center of the vehicle body.

[0080] Since the terrain of the chestnut orchard is often a terrain with large undulations and slopes, in order to safely pick up the chestnuts that have fallen to the ground, the power unit 1002 is arranged downward, and a layout with good weight balance is adopted. When the operator stands on the step of the operator step portion 900, such weight balance is further improved.

[0081] A stopper member S that prevents the chestnuts and chestnut husks from being dragged around as the rotating cylindrical member 110 rotates is attached near the rear surface of the rotating cylindrical member 110 so that the chestnuts and chestnut husks are separated from the rotating cylindrical member 110 and sent backward.

[0082] The chestnuts and chestnut husks are locked by a stopper member S having, for example, an I-shaped locking material and reliably sent backward, so the working efficiency is improved.

[0083] In addition, the program of the invention related to the present invention is a program for causing a computer to execute the operations of all or part of the steps (or processes, operations, actions, etc.) of the chestnut harvesting work vehicle operation control method of the invention related to the present invention described above, and is a program that operates in cooperation with the computer.

[0084] Also, the recording medium of the invention related to the present invention is a recording medium that records a program for causing a computer to execute all or part of the operations of all or part of the steps (or processes, operations, actions, etc.) of the chestnut harvesting work vehicle operation control method of the invention related to the present invention described above, and is a computer-readable recording medium in which the read program is used in cooperation with the computer.

[0085] Note that the "some steps (or processes, operations, and actions, etc.)" described above mean one or some of those multiple steps.

[0086] Also, the "operation of the step (or process, operation, and action, etc.)" described above means all or part of the operations of the above-described step.

[0087] Also, one usage form of the program of the invention related to the present invention may be a form in which it is transmitted through a transmission medium such as the Internet, light, radio waves, or sound waves, read by a computer, and operates in cooperation with the computer.

[0088] Also, the recording medium includes ROM (Read Only Memory), etc.

[0089] Also, the computer is not limited to pure hardware such as a CPU (Central Processing Unit), and may include firmware, an OS (Operating System), and further peripheral devices.
