The sampling device Sd is provided as a characteristic configuration of the present embodiment. Next, the configuration of the sampling device Sd, which is a characteristic configuration of the present embodiment, will be described.

[Description of Characteristic Configuration of this Embodiment]
As shown in FIGS. 3 to 13, the sampling device Sd is arranged in the grain storage unit 11, and sampling means 700 that samples the sampling grain stored in the grain storage unit 11 over time. A sample storage means 800 that is arranged outside the grain storage unit 11 and that can sequentially store a predetermined amount of the first grain sampled by the sampling means 700 in a plurality of sample storage chambers 845 with identification numbers; Correspondence association means for associating the support means 900 for supporting the sample storage means 800, the sampling grain in each sample storage chamber 845 assigned with an identification number, and the harvesting position of the field where the sampling grain is harvested. The sample storage means 800 is detachably attached to the support means 900 outside the apparatus. To have.

  Here, the grain storage part 11 to be described later is formed in a funnel shape in which the bottom part 30 extends in the front-rear direction and the left and right widths are gradually reduced to form a triangular prism-shaped internal space 40 formed inside the bottom part 30. Inside, an axial line extends in the front-rear direction, and a bottom conveyance conveyor 18 for carrying out the stored first grain is disposed in the triangular prism-shaped external space 50 formed on the right outer side of the bottom 30. The sample storage means 800 and the support means 900 for supporting the sample storage means 800 are disposed.

  The sampling means 700 is arranged to extend in the vertical direction along the inner wall (inner surfaces of the rear wall 22 and the right wall 24) of the grain storage unit 11, and the upper end of the sampling means 700 is the grain. It arrange | positions in the upper part in the storage part 11, and is comprised with the collection part 710 which collects a fixed quantity of the first grain, and the middle part of the sampling means 700 is arrange | positioned in the middle part in the grain storage part 11 The lower part of the sampling means 700 is arranged at the lower part in the grain storage part 11 and is directed from the bottom part 30 to the triangular prism-shaped external space 50. And a communication connecting portion 780 that is connected to and connected to the sample storage means 800 disposed in the external space 50. The sampling unit 700 can supply the sampled first grain to the sample storage unit 800 in a certain amount sequentially.

  The collecting unit 710 is provided with a pair of inflow / outlet side open / close valves 719 and 720 that are reciprocally opened / closed by a valve drive motor 761 as a valve open / close actuator, and the outflow side open / close valve 720 is closed. By opening the side opening / closing valve 719, a temporary storage space 730 in which a certain amount of sampling grain is temporarily stored is formed.

  When a certain amount of sampling grain stored in the temporary storage space 730 is detected by a storage amount detection sensor 732 as a storage amount detection means, a valve drive motor is connected via a CPU 112 as a control means described later. The flow-out side on-off valve 720 is opened by 761 and the inflow-side on-off valve 719 is closed, so that a certain amount of the first grain stored in the temporary storage space 730 is stored in each sample. These are sequentially supplied into the storage chamber 845.

  The sample storage means 800 has a plurality of sample storage chambers 845 formed by subdividing so as to be able to store the first amount of grain that is sequentially supplied.

  That is, the sample storage means 800 includes a storage container 810 formed in a disk-like box shape, and a mounting portion 820 provided at the center of the storage container 810. The storage container 810 is provided around the mounting portion 820. A plurality of sample storage chambers 845 are formed in the circumferential direction.

  The storage container 810 is fixedly attached and fixed to the support means 900 in a detachable manner, and is placed in the fixed-side container piece 830, and the container 810 is subdivided in the circumferential direction to open a plurality of peripheral end faces. A rotation-side container piece 840 in which the sample storage chamber 845 is formed. On the peripheral wall of the fixed side container piece 830, a sample inlet 836 that coincides with the peripheral end opening surface of any one of the sample storage chambers 845 is formed, while the rotation side container piece 840 includes one sample storage chamber 845. The closed end portion 847 is formed by closing the peripheral end opening surface.

  The support unit 900 can sequentially move the sample storage chamber 845 to the sample storage position. In other words, the support unit 900 has a moving unit 990 for moving the sample storage chamber 845 via the attachment unit 820 of the sample storage unit 800 and a storage position for detecting the sample storage chamber 845 moved to the sample storage position by the moving unit 990. A pickup sensor 971 as detection means and a position detection sensor 981 as position detection means are provided. The pickup sensor 971 and the position detection sensor 981 will be described later.

  Then, the movement operation of the sample storage chamber 845 by the moving unit 990 is linked to the closing operation of the outflow side opening / closing valve 720, and the CPU 112 described later drives and controls the moving unit 990 based on the detection information of the pickup sensor 971. Thus, each sample storage chamber 845 is sequentially waited at a sample storage position (a position immediately below the sample inlet 836), and a certain amount of sampling grains supplied from the collection unit 710 to each sample storage chamber 845 is received. They are accommodated sequentially. Here, the CPU 112 to be described later can acquire the harvest position of the first grain as position information.

  The support unit 900 is provided with a moving unit 990 that rotates the storage container 810 to rotate the sample storage chamber 845. Then, the sample storage chamber 845 is rotated and moved by the moving unit 990 so that the first grain sampled over time can be sequentially stored in each sample storage chamber 845. That is, the movement operation of the sample storage chamber 845 by the moving unit 990 is linked to the closing operation of the outflow side opening / closing valve 720, and the CPU 112 drives and controls the moving unit 990 based on the detection information of the pickup sensor 971. The sample storage chambers 845 are sequentially placed on standby at the sample storage location so that a fixed amount of the first grain supplied from the collection unit 710 is sequentially stored in each sample storage chamber 845.

  More specifically, the rotation side container piece 840 is detachably attached to the moving part 990 via the attachment part 820 so that the rotation side container piece 840 can be rotated. Then, by rotating the moving unit 990, the sample storage chamber is passed through the sample inlet 836 and the peripheral opening surface of the sample storage chamber 845 that match the first grain sampled continuously by the sampling means 700. The sample storage chamber 845 can be stored in the sample storage chamber 845 and cannot be stored in the sample storage chamber 845 through the corresponding sample inlet 836 and the closed surface portion 847 of the sample storage chamber 845.

  The correspondence associating unit 208 associates the identification number assigned to the sample storage chamber 845 with the harvested position of the sampling kernel when a certain amount of sampling kernel is supplied into the sample storage chamber 845. ing. That is, based on the position information acquired by the CPU 112, the valve drive motor 761 is driven and controlled by the CPU 112, the outflow side on / off valve 720 is closed, and the inflow side on / off valve 719 is opened. Then, a temporary storage space 730 is formed, and sampling grains are stored in the temporary storage space 730. When the stored amount detection sensor 732 detects that the stored sampling grain has reached a certain amount, the valve drive motor 761 is driven and controlled by the CPU 112 that has acquired the detection information, and the outflow side opening / closing valve 720 is opened. In addition, the inflow side on-off valve 719 is closed. Then, a certain amount of sampling grain stored in the temporary storage space 730 is supplied into the sample storage chamber 845. At this time, the identification number assigned to the sample storage chamber 845 is associated with the harvested position of the sampling grain.

  In the sampling device Sd configured in this way, the sampling means 700 can sample the sampling grain over time, and can sequentially store the first sampled grain in the sample storage means 800, Since the sample storage means 800 can be attached to and detached from the support means 900 outside the apparatus, the sampled sampling grains can be easily extracted from outside the apparatus as appropriate by sequentially storing the sampled grains in the sample storage means 800. be able to. Then, after the harvesting operation is finished, the first grain in the sample storage unit 800 can be peeled off, and thereafter the internal quality can be accurately measured.

  And since the sample storage means 800 and the support means 900 are arrange | positioned in the triangular prism-shaped external space 50 formed in the right outer side of the bottom part 30 of the grain storage part 11, the sample storage means 800 and support are provided. The means 900 can be disposed within the width of the original machine body, and the sample storage means 800 can be easily attached to and detached from the support means 900 outside the machine.

  Further, the lower end portion of the sampling means 700 is disposed in the bottom portion 30 in the grain storage portion 11 and is disposed in the outer space 50 so as to penetrate from the bottom portion 30 toward the triangular prism-shaped outer space 50. Since the communication connecting portion 780 is connected to and connected to the sample storage means 800, the sampling grain sampled by the sampling means 700 can be securely stored in the sample storage means 800 via the communication connection portion 780.

  At this time, before the fixed amount of the first grain is supplied to the sample storage unit 800 by the sampling unit 700, the sample storage chamber 845 of the sample storage unit 800 that stores the supplied fixed amount of the first grain, Since the moving unit 990 of the support unit 900 is moved to the sample storage position and can be on standby, a certain amount of supplied first grain can be securely stored in the sample storage chamber 845 on standby. .

  And since the rotation side container piece 840 is rotationally driven by the moving part 990, since the first grain sampled over time can be sequentially accommodated in each sample storage chamber 845, the sample storage means 800 Can be formed in a compact manner, and the first grain sampled in each sample storage chamber 845 can be stored smoothly.

  In addition, by rotating the moving unit 990, the first grain sampled continuously by the sampling means 700 is stored through the sample inlet 836 and the peripheral opening surface 846 of the sample storage chamber 845. The sample storage chamber can be stored in the chamber 845 and cannot be stored in the sample storage chamber 845 through the corresponding sample inlet 836 and the closed surface portion 847 of the sample storage chamber 845. In 845, the most sampled grain can be firmly stored, and when the sample storage means 800 is removed from the support means 900, it is stored in the sample storage chamber 845 that cannot be stored. In addition, it is possible to steadily prevent the grain from flowing out.

  In addition, the correspondence association unit 208 can associate and associate the sampling grain in each sample storage chamber 845 with the identification number and the harvest position of the field where the sampling grain is harvested. Management of the grain is easy. Then, after the harvesting operation is finished, the first grain in the sample storage unit 800 can be peeled off, and thereafter the internal quality can be accurately measured.

  That is, when a certain amount of the first grain stored in the temporary storage space 730 is detected by the storage amount detection sensor 732, the outflow side opening / closing valve 720 is opened by the valve drive motor 761 via the CPU 112. In addition, the inflow side on-off valve 719 is closed so that a certain amount of the first grain stored in the temporary storage space 730 is sequentially supplied into each sample storage chamber 845. Therefore, the required amount of the first grain accommodated in the sample storage chamber 845 can be ensured to be constant.

  Then, the movement operation of the sample storage chamber 845 by the moving unit 990 is linked to the closing operation of the outflow side opening / closing valve 720, and the CPU 112 drives and controls the moving unit 990 based on the detection information of the pickup sensor 971. The sample storage chambers 845 are sequentially kept in standby at the sample storage positions, so that a certain amount of the first grain supplied from the collection unit 710 is sequentially stored in each sample storage chamber 845. In the sample storage chamber 845, it is possible to prevent the grain from overflowing to the outside of each sample storage chamber 845 and being lost unnecessarily.

  At this time, since the identification number assigned to the sample storage chamber 845 and the harvest position of the first grain are associated with each other, the management of the first grain in the storage container 810 is facilitated and the harvest is performed. After the work is finished, it can be peeled off and the internal quality can be measured smoothly and steadily. And the measurement result (measurement data) of internal quality can be used for traceability and cultivation management of the next fiscal year.

  In addition, the sample association unit 208 associates the sampled grains stored in the sample storage chambers 845 by the sample storage unit 800 with the harvesting position of the field G (see FIG. 14) from which the sampled grains are harvested. Therefore, it is possible to grasp the internal quality status of the first grain in the same field based on the measurement data of the internal quality of the sampling grain corresponding to the harvest position in the field. Therefore, the mapping illustrated by superimposing the internal quality situation and the harvesting position of the first grain on the map of the field G can be created, and the mapping can be used for traceability and cultivation management in the next year.

  Since the identification number given to each sample storage chamber 845 and the harvesting position of the field G where the sampled grains in each sample storage chamber 845 are harvested can be correlated and associated with each other by the correspondence association unit 208. Based on the measurement data, the internal quality of the sampled grain corresponding to the harvesting position can be accurately grasped by subdividing the internal quality of the first grain in the same field. Therefore, detailed and effective mapping that can be used for traceability and cultivation management in the next year can be created.

  Next, the configuration of the sampling device Sd, which is the characteristic configuration described above, will be described more specifically.

And the first grain conveyed to the terminal part by the cereal conveyor 15 is thrown into the storage part main body 20 in a diffused state from the input part 16 by the scattering blades 17 that rotate integrally with the cereal conveyor 15. I try to do it. At this time, the first grain to be thrown in is scattered in a wide range with a momentum to collide with at least the front wall 21, the rear wall 22, the right side wall 24, and the ceiling wall 25 of the storage unit body 20.

(Description of the configuration of the sampling device)
As described above, the sampling device Sd includes the sampling unit 700, the sample storage unit 800, the support unit 900, and the correspondence association unit 208.

  The sampling means 700 includes a collecting unit 710, a flow lower part 770, and a communication connecting part 780. The collection unit 710 is formed of a collection body 711 that collects the sampling grain and a storage body 712 that is arranged in a communication state directly below the collection body 711 and temporarily stores the collected sampling grain. . The collection body 711 is formed in a square funnel shape with the upper and lower surfaces opened and gradually reduced in width downward. The storage body 712 is provided with a temporary storage function part 714 on the front surface of a mounting plate 713 formed in a rectangular plate shape, and an operation mechanism part 715 and a function driving part 716 on the rear surface of the mounting plate 713. .

  As shown in FIG. 5, a rectangular attachment port 729 is formed in the upper right portion of the rear wall 22 of the grain storage unit 11. And the storage body 712 arrange | positions the temporary storage function part 714 in the grain storage part 11 through the attachment port 729, and is the part of the rear wall 22 of the grain storage part 11 which forms the peripheral part of the attachment port 729. The peripheral edge of the mounting plate 713 is brought into contact with the superposed state and is detachably mounted by mounting screws 717.

And the flow path formation body 718 attaches the rear end edge part of both side surface formation piece 721,722 to the front surface of the attachment plate 713, and forms the flow path through which the sampling grain flows downward from above. doing.

  The inflow side on-off valve 719 is formed by an inflow side valve support shaft 724 having an axial line in the front-rear direction, and a rectangular plate-shaped inflow side valve body 725 in which a base edge is attached to the inflow side valve support shaft 724. Yes. The upper end portion of the left side surface forming piece 721 is arranged to be positioned below the upper end portion of the right side surface forming piece 722 by a certain width, and flows into a position directly above the upper end portion of the right side surface forming piece 722. The side valve support shaft 724 is disposed so as to protrude forward from the front surface of the mounting plate 713. The inflow side opening / closing valve 719 has an inflow side valve opening posture in which the inflow side valve body 725 is tilted to the left side about the inflow side valve support shaft 724 just below the lower end opening 728 of the collection body 711. The posture can be changed between P1 and the inflow side valve closing posture P2 in which the inflow side valve body 725 is tilted rightward.

  In the inflow side valve opening posture P1, the inflow side valve main body 725 that opens the upper part of the flow path causes the sampling grain flowing down from the lower end opening 728 of the collection body 711 to flow into the temporary storage function unit 714 side. I have to. In the inflow side valve closing posture P2, the leading edge of the inflow side valve main body 725 is close to the upper end of the right side surface forming piece 722 so as to close the upper part of the flow path. At the same time, the inflow side valve main body 725 that closes the upper part of the flow path allows the sampling grain flowing down from the lower end opening 728 of the collection body 711 to be left outside the temporary storage function unit 714 in the storage unit main body 20. It flows down and guides in the direction so as not to flow into the temporary storage function part 714. As a result, sampling is interrupted or stopped.

  The outflow side on-off valve 720 is formed of an outflow side valve support shaft 726 whose axis is directed in the front-rear direction, and a rectangular plate-shaped outflow side valve body 727 having a base edge attached to the outflow side valve support shaft 726.

The outflow side opening / closing valve 720 has an outflow side valve closing posture P3 in which the outflow side valve body 727 is tilted leftward about the outflow side valve support shaft 726, and the outflow side valve body 727 is in a horizontal state. It is possible to change the posture with the outflow side valve-opening posture P4 that is in a suspended state by being tilted downward. In the outflow side valve closing posture P3, the leading edge of the outflow side valve main body 727 comes close to the middle part of the left side surface forming piece 721 so as to close the middle part of the flow path. At this time, the flow path in which the upper part is opened while the midway part is closed forms a temporary storage space 730.

The storage amount detection sensor 732 detects that the sampling grain stored in the temporary storage space 730 has reached a certain height, that is, a certain amount. The storage amount detection sensor 732 is connected to the input side of the CPU 112 described later. Then, when acquiring the detection information from the storage amount detection sensor 732, the CPU 112 generates control information for opening the outflow side opening / closing valve 720, and transmits the generated control information to the function driving unit 716 described later. The function driving unit 716 is driven and controlled. As a result, a certain amount of sampling grain temporarily stored in the temporary storage space 730 flows down.

  A limit amount detection sensor (for example, a static detection sensor) is provided at a lower portion of the left side surface (outer side surface) of the left cover piece 734 of the relay cover body 733, that is, a left side position of the inflow side on-off valve 719 via a sensor mounting second bracket 738. A capacitance type proximity sensor) 737 is attached. The limit amount detection sensor 737 detects that the first grain stored in the storage unit body 20 has reached a certain height, that is, a certain amount (sampling limit amount). The limit amount detection sensor 737 is connected to the input side of the CPU 112 described later. Then, when acquiring the detection information from the limit amount detection sensor 737, the CPU 112 generates control information for closing the inflow side opening / closing valve 719, and transmits the generated control information to the function driving unit 716 described later. The function driving unit 716 is driven and controlled. As a result, sampling is stopped.

The inflow side long hole 755 and the outflow side long hole 757 intersect with each other in the front-rear direction, and a connecting pin 758 having an axis line in the front-rear direction is slidably passed through the intersecting portion. The connecting pin 758 protrudes from a distal end portion of a drive arm 759 that extends a base end portion (rear end portion) in the left-right direction. The drive arm 759 has a base end attached to a drive shaft 762 of a function drive unit 716 described later.

  The function drive unit 716 has a gear case 760 attached to the rear side of the support plate 750, and a valve drive motor 761 as a valve opening / closing actuator is linked to the gear case 760.

The valve drive motor 761 is a so-called clutch motor, and is configured such that the drive arm 759 attached to the drive shaft 762 performs an arc motion within a predetermined rotation range (approximately 180 ° rotation range in this embodiment). Yes. Therefore, by rotating the drive shaft 762 of the valve drive motor 761 forward and backward, the drive arm 759 attached to the drive shaft 762 can be reciprocated in a circular motion within a predetermined rotation range of approximately 180 degrees.

  When the valve drive motor 761 is driven to rotate forward, the drive shaft 762 is rotated clockwise in the front view shown in FIG. 10 via the gear case 760, and the drive arm 759 attached to the drive shaft 762 is rotated clockwise.

The support shaft 724 and the outflow side valve support shaft 726 are rotated forward. As a result, the inflow side valve body 725 takes the inflow side valve opening posture P1, while the outflow side valve body 727 takes the outflow side valve closing posture P3. That is, the inflow side valve body 725 and the outflow side valve body 727 are reciprocally opened and closed. When the valve drive motor 761 is driven to rotate in the reverse direction, the inflow side valve body 725 adopts the inflow side valve closing posture P2 while the outflow side valve body 727 is outflowed, contrary to the case where it is driven to rotate forward. The side valve opening posture P4 is taken.

  The flow lower part 770 is formed of an upper flow-down body 771 formed in a quadrangular cylinder extending straight in the vertical direction and a lower flow-down body 772 formed in a quadrangle cylinder extending in a front-rear and rear-inclined shape. ing. The upper end of the upper flow-down body 771 is disposed in the vicinity immediately below the flow path forming body 718. The upper end of the lower flow body 772 is connected to the lower end of the upper flow body 771 to form a “<” shape in a side view. A communication connecting portion 780 described later is connected to the lower end of the lower flow body 772. And the sampling grain flowed down from the temporary storage function part 714 is made to flow down while sliding to the upper flow-down body 771 → the lower flow-down body 772 → the communication connection part 780.

A positioning piece 834 and a pair of front and rear fixing pieces 835 and 835 project from the peripheral edge of the side piece 832 in the radial direction. A sample inlet 836 that is formed in a rectangular shape having the same shape as the lower end opening 787 of the communication connecting portion 780 is provided at the top of the peripheral piece 833. The sample inlet 836 is provided at the front and rear edges of the sample inlet 836. The projecting projections 837 and 837 are provided so as to face each other in the front-rear direction. That is, the positioning projections 837 and 837 are externally fitted to the lower end opening 787 of the communication connecting portion 780 and positioned to align the lower end opening 787 of the communication connecting portion 780 and the sample inlet 836 in the vertical direction. It is possible. Reference numeral 838 denotes a positioning hole formed in the positioning piece 834, and 839 denotes a fixing hole formed in the fixing piece 835.

Each sample storage chamber 845 opens the peripheral end opening surface 846 and can store sampling grains, and in one of the sample storage chambers 845, a closed surface portion 847 is formed, The closed chamber 848 cannot accommodate the sampling kernel. Therefore, the closed chamber 848 can be placed in alignment with the sample inlet 836 so that the storage container 810 can be closed and the sampling grain can be prevented from flowing into the sample storage chamber 845. In addition, it is possible to allow the sampling grain to flow out of the sample storage chamber 845 that stores the sampling grain. In addition, a visual recognition window 849 that allows the inside of the sample storage chamber 845 to be visually recognized is formed in the outer piece 842. Therefore, the accommodation situation of the sampling grain accommodated in the sample accommodation chamber 845 through the visual recognition window 849 can be appropriately visually recognized from outside the apparatus.

  The attachment portion 820 is formed in a disc ring shape and is stretched in the central opening of the outer piece 842. The attachment portion 820 is formed with a plurality of screw insertion holes 821 penetrating in the left-right direction.

  The rotation-side container piece 840 provided with the attachment portion 820 can be fitted into the fixed-side container piece 830 formed to have a slightly larger diameter than the rotation-side container piece 840 so that it can be inserted and removed from the right side surface with the entire surface opened. The storage container 810 can be closed by arranging the closed chamber 848 in alignment with the sample inflow port 836. The closed storage container 810 is moved from the support means 900 described later to the cartridge. It is detachable from the formula.

  The support means 900 superimposes the upper half of the inner side surface of the hanging support plate 910 formed in a laterally long rectangular shape in the front-rear direction on the lower half of the outer surface of the standing support piece 783 that forms part of the support 782. The hanging support plate 910 is suspended from the upright support piece 783 by being attached to the state. A support frame 920 that extends in the front-rear direction and has a U-shaped cross section is attached to the outer surface of the hanging support plate 910. In the middle of the support frame 920, a rotation support shaft 930 having an axis line in the left-right direction protrudes rightward. A cylindrical boss portion 931 is externally fitted to the rotation shaft 930 so as to be rotatable concentrically. A large diameter gear 932 is concentrically attached to the inner end portion of the peripheral surface of the boss portion 931, while a rectangular plate-like attachment piece 933 is concentrically attached to the outer end portion of the peripheral surface. 990 is configured. The attachment piece 933 is formed with a plurality of screw holes 934 that coincide with the screw insertion holes 821 of the attachment portion 820. Then, the inner side surface of the mounting portion 820 is brought into surface contact with the outer side surface of the mounting piece 933, and the screw insertion holes 821 and the screw holes 934 are matched to each other. By screwing 935, the rotation-side container piece 840 can be interlocked and connected to the boss portion 931. Further, the rotation-side container piece 840 can be removed from the boss portion 931 by screwing the knurled screw 935.

  A positioning pin 940 projects from the rear end of the support frame 920 toward the right side. The positioning-side container piece 830 can be positioned on the support frame 920 by fitting the positioning hole 838 of the positioning piece 834 into the positioning pin 940. A pair of front and rear cylindrical fixed female screws 950 and 950 project from the front lower portion and the rear lower portion of the hanging support plate 910 toward the right side. Fixing holes 839 and 839 of a pair of front and rear fixing pieces 835 and 835 are aligned with the respective fixing female screws 950 and 950, and a screw 935 with a pinch is inserted into each fixing female screw 950 and 950 via the fixing holes 839 and 839. By screwing, the stationary container piece 830 can be fixed to the hanging support plate 910. Further, the fixed-side container piece 830 can be removed from the hanging support plate 910 by screwing the knurled screw 935.

  A rotation drive gear case 960 is attached to the front portion of the hanging support plate 910, and a rotation drive motor 961 as a rotation drive actuator is linked to the rotation drive gear case 960. The rotational drive gear case 960 is provided with a pinion gear 962 meshed with the large diameter gear 932. Then, by driving the rotation drive motor 961, the large-diameter gear 932 is rotated via the pinion gear 962, and the rotation-side container piece 840 is concentrically connected via the boss portion 931 that rotates integrally with the large-diameter gear 932. Can be rotated.

  A non-contact type electromagnetic pickup sensor 971 as a receiving position detecting unit is opposed to a tooth portion which is a peripheral end portion of the large-diameter gear 932 via a first sensor mounting piece 970 at a front lower portion of the hanging support plate 910. And arranged close to each other. The pickup sensor 971 is electrically connected to the input side of the CPU 112, which will be described later, while the rotational drive motor 961 is electrically connected to the output side of the CPU 112. When the large-diameter gear 932 is rotated by the rotational drive of the rotational drive motor 961, the pickup sensor 971 detects the rotational angle of the large-diameter gear 932. The detection of the rotation angle of the large-diameter gear 932 by the pickup sensor 971 here is the detection of the storage position of the sampling storage chamber. Then, when the detection information of the pickup sensor 971 is transmitted to the CPU 112, the CPU 112 generates control information based on the transmission information, and the generated control information is output to the rotation drive motor 961, and the large diameter gear 932 is output. Is rotated by a predetermined rotation angle, the rotation drive of the rotation drive motor 961 is controlled to stop. As a result, the rotation-side container piece 840 is intermittently rotated so that the peripheral end opening surface 846 of the sample storage chamber 845 is sequentially rotated by a predetermined angle from the position not aligned with the sample inlet 836 to the position aligned. Thus, the accommodation position of the sampling grain is determined.

  A non-contact type position detection sensor (for example, a capacitive proximity sensor) 981 as a position detection means is disposed via a second sensor mounting piece 980 in the middle lower part of the hanging support plate 910, and the position detection sensor. The detected piece 982 protruding from the inner surface of the large-diameter gear 932 is detected by 981, and the initial setting position of the large-diameter gear 932 is detected. The position detection sensor 981 is electrically connected to the input side of the CPU 112 described later. Then, after the key switch of the combine A is disconnected, when the key switch is connected again, the large-diameter gear 932 is rotated to the initial setting position where the position detection sensor 981 detects the detected piece 982, The large-diameter gear 932 is rotated by the rotation drive motor 961 from the initial setting position to the rotation angle position of the large-diameter gear 932 immediately before the key switch stored in the CPU 112 is connected. As described above, when the key switch is connected, by always resetting the large-diameter gear 932 from the initial setting position, there is a problem that the sample storage chamber 845 is displaced from the sample inlet 836 for some reason. Is preventing.

  As shown in FIGS. 2 to 4, a moisture sensor 995 as moisture detection means is provided on the inner surface of the front wall 21 of the reservoir body 20. The moisture sensor 995 collects a part of the first grain introduced into the storage unit main body 20 from the input unit 16 and measures the amount of water. The moisture sensor 995 includes a pair of electrode rollers 997 and 997 facing each other and an opening / closing mechanism 998 that opens and closes the electrode rollers 997 and 997 directly above the electrode case 996.

  When the ceiling portion of the sensor case 996 is opened by the opening / closing mechanism 998 by the opening / closing mechanism 998, the sensor case 996 further includes a pair of electrode rollers 997. , 997, a part of the first grain input from the input unit 16 flows in, and a part of the first input grain is crushed by the electrode rollers 997, 997, thereby crushing The water content of the first grain is measured by both electrode rollers 997 and 997. Here, the amount of the first grain that flows into the sensor case 996, that is, the amount of the first grain whose moisture content is measured is approximately proportional to the opening time of the sensor case 996 by the opening / closing mechanism 998, The opening time can be appropriately set in the display device 100 described later. An opening / closing mechanism 998 is connected to the output side of the CPU 112 so that the opening / closing drive of the opening / closing mechanism 998 is controlled by the CPU 112. Further, when the sensor case 996 is closed by the opening / closing mechanism unit 998, the first grain input from the input unit 16 is prevented from flowing into the sensor case 996.

  More specifically, the pair of electrode rollers 997 and 997 are rotated so that a part of the first grain thrown in from the throwing portion 16 enters between the electrode rollers 997 and 997, and rotate. The electric resistance value of the first grain that is crushed between both electrode rollers 997 and 997 is detected while crushing the grain most between 997 and 997 (in other words, crushing in other words), and the detected electrical resistance The value can be output as a signal (information) about the moisture content of the first grain. The pair of electrode rollers 997 and 997 is electrically connected to a CPU 112 described later, and transmits a signal (information) related to the detected grain moisture to the CPU 112.

  The moisture sensor 995 has an identification number n (n = 1 to 9 in the present embodiment) given at the time of detecting the moisture amount and an identification address BnN (BnN = Bn1 to Bn9 in the present embodiment) which is a harvesting position. The correspondence association unit 208, which will be described later, is configured to be associated in a one-to-one correspondence. And about the water | moisture content of the first grain measured during the harvesting operation, while obtaining an average value, a maximum value, a minimum value, a standard deviation, and a number of measurement points, every predetermined water content range (for example, moisture content 15%) The frequency distribution of every 30% between 30% and 30% is aggregated, so that a histogram is created and the created histogram is displayed and output on the display unit 118 of the display device 100 described later. Yes. Furthermore, the measured moisture content of the first grain is transmitted to the server 400 of the harvest management facility B via the network 500 described later, and is managed by the server 400.

  In the field G, the harvesting position of the combine A from which the sampling grain is harvested is obtained as position information using a “satellite positioning system” described later. That is, as shown in FIG. 15, the image processing unit 212 included in the display device 100 to be described later superimposes a grid-like (grid-like grid) virtual section K on the map information M of the farm field G with the virtual section lines Lk. The identification address Bn1... BnN is set in each virtual section K, and the sample storage chamber 845 in which any one of the identification addresses BnN is harvested and collected at the identification address BnN and the sampling grain is stored. Are associated with each other in a one-to-one correspondence by the association unit 208 included in the display device 100 described later.

  The correspondence associating unit 208 assigns identification numbers 1... N to each sample storage chamber 845 in advance, while preliminarily plotting the field G in a virtual section K, and at the harvesting position where the sampling grain is harvested in the virtual section K. By setting the identification addresses Bn1... BnN, the identification number n and the identification address BnN are associated with each other in a one-to-one correspondence. That is, each sample storage chamber 845 is assigned an identification number 1... N, which is a serial number, corresponding to the order in which the sample storage chambers are rotated and transferred. Thus, the sampled grains are collected in a predetermined amount in each of the sample storage chambers 845 that are intermittently rotationally transferred by the support means 900.

  Then, predetermined positions Cp1... Cpn (in this embodiment, Cpn = Cp1 to Cp9) in each identification address Bn1... BnN of the virtual section K are the position information that the combine A has reached the central part in the identification address. When the GPS processing unit 128 acquires from the GPS satellite 600 and the positional information acquired by the GPS processing unit 128 is supplied to the CPU 112, the CPU 112 causes the valve driving motor 761 to input the inflow side on-off valve 719 via the function driving unit 716. And the outflow side opening / closing valve 720 are controlled to be reciprocal opening / closing valves, and at this time, the sampling grains are stored in the sample storage chamber 845 disposed in a state where the peripheral surface is opened directly below the communication connecting portion 780. The identification numbers 1... N attached to the chamber 845 and the identification addresses Bn1... BnN where the sampling grains in the collection container 51 are collected are By being associated with corresponding pairs 1, it has to be identified in the identification address Bn1 ... BNN. That is, the identification number 1, the identification address Bn1, and the predetermined position Cp1, the identification number 2, the identification address Bn2, the predetermined position Cp2,..., The identification number n, the identification address BnN, and the predetermined position Cpn are associated with each other. The identification number n, the identification address BnN, and n and N at the predetermined position Cpn are positive integers, respectively.

  For example, as shown in FIG. 15, when the lower right portion of the field G is set as the harvest start position Ps, the grain harvesting operation is performed in a spiral manner along the inner peripheral edge of the field G toward the center position. Do it. When the virtual section K is set so as to be divided into nine grids along the virtual section line Lk, the identification addresses Bn1... Bn9 (shown only by numbers in FIG. 9) are arranged in the order in which the harvested products are harvested in the nine sections. In addition, the coordinates of the predetermined positions Cp1... Cp9 are specified in the identification addresses Bn1... Bn9 (displayed as black dots in FIG. 9). Therefore, strictly speaking, a predetermined position Cpn of one of the identification addresses BnN and an identification number n of the sample storage chamber 845 in which the sampling grain is stored while being harvested and collected at the identification address BnN of the predetermined position Cpn. Are associated in a one-to-one correspondence by the correspondence association unit 208. Z in FIG. 15 is a ridge formed around the field G.

(Explanation of combine location information acquisition configuration)
Next, the structure which acquires the positional information on the combine A is demonstrated. In other words, the position information of the combine A is the positioning target for the whole earth in a “satellite positioning system” that measures the latitude, longitude, altitude, etc. of the current position on the ground using an artificial satellite (three-dimensional positioning). Can be obtained by adopting a Global Navigation Satellite System (GNSS) Sy, and in this embodiment, it is obtained by employing a GPS (Global Positioning System) that is representative of this system Sy. I am doing so. In addition, even when the “satellite positioning system” is not adopted, that is, even when position information cannot be acquired, the field identification number (ID) is assigned to each one-stroke field, and the field identification number of each one-stroke field and the one-stroke field are collected. It is also possible to manage the identification number of the sampled grain in a one-to-one correspondence.

  More specifically, the combine A communicates with the GPS satellite 600 and can acquire position information (for example, current position information) of the display device 100 disposed in the operation unit of the combine A. The display device 100 allows the operator to operate a rectangular plate-shaped display unit 118 that constitutes a part of the display device 100 while visually recognizing it in a sitting posture.

  The sampled grains harvested and collected by the combine A are stored in the sample storage chambers 845, and as shown in FIG. 14, a cartridge-type storage container 810 is carried into the harvest management facility B, The internal quality of the sampled grain is measured and the measured value is managed while being associated with the harvest position of G.

  In other words, the harvest management facility B includes a post-processing system 300, and the post-processing system 300 is subjected to a drying process 310 for drying the sampling grain carried in by the combine A and a drying process 310. Peeled (sheddering) processing the sampled grain, and the internal quality measurement for measuring the moisture value (moisture content) and the taste as the internal quality of the sampled grain that has been subjected to the strawing process 320 Step 330. Taste measurement is performed by irradiating the first grain with near-infrared light and analyzing the absorption spectrum based on the spectral analysis of the transmitted light. Based on the analysis result, moisture, protein, amylose, fatty acid contained in the first grain Analyze the amount of ingredients such as degrees, score them individually, and score the total score.

  Reference numeral 812 in FIG. 14 denotes an IC tag attached to the peripheral piece 833 of the fixed-side container piece 830 so as to correspond to each sample storage chamber 845. The IC tag 812 stores an identification number and the like of each sample storage chamber 845. Has been. Reference numeral 312 denotes a dryer. The storage container 810 containing the sampling grain is put in the dryer 312 as it is, and the sampling grain is dried. Reference numeral 322 denotes a hulling machine, and a storage container 810 is rotatably supported at a position directly above the hulling machine 322, and the sampling grains are caused to flow down into the hulling machine 322 from each sample storage chamber 845. Moulting the grains. 332 is a taste analyzer, and 334 is a peeled grain as a taste analysis material, and the grain is analyzed by the taste analyzer. These processes are managed based on an identification number or the like stored in the IC tag 812.

  The harvest management facility B is provided with a server 400 and a database (DB) 450 connected thereto, and the server 400 has an internal quality of the sampling grain measured in the internal quality measurement step 330 described above. In addition, map information in each field G, farm work history information, and the like are managed. These pieces of information are information appropriately transmitted from the display device 100 and information stored in the database 450 in advance. The measurement result (measurement data) of the internal quality of the sampling grain stored in the database 450 is traceable. It can be used for cultivation management in the next year. That is, based on the measurement result (measurement data) of the internal quality of the sampled grain stored in the database 450, that is, based on the measurement result of the internal quality of the sampled grain in the previous year of the specific field G, in the specific field G The first grain harvested in this year can be appropriately post-processed (drying process in the drying process 310 or hulling in the hulling process 320). In the first year when the product is brought into the harvest management facility B, there is no measurement result of the previous year, so that the post-processing system 300 post-processes the sampled grain and measures and manages its internal quality. Before the sampled grain is post-processed, the first harvested grain is post-processed according to the identification number based on the measurement value measured by the moisture sensor 995.

  The database 450 also stores map information and the like from a predetermined location such as an operator's home to each field G. The server 400 can communicate with the combine A display device 100 via a network 500 such as the Internet. The server 400 receives the farm work status (for example, the movement route during the farm work of the combine A) in real time from the display device 100 of each combine A, and stores it in the database 450 as farm work history information. Further, the server 400 transmits past farm work history information of each desired field G to the display device 100 of each combine A in response to a request from each operator of the plurality of combine As.

(Description of control operation of sampling device)
FIG. 16 is a flowchart showing the control operation of the sampling device Sd. Hereinafter, the control operation of the sampling device Sd will be described with reference to the flowchart of FIG.

  That is, the sampling device Sd is started by operating an input unit 122 provided in the display device 100 described later. Then, a predetermined position Cpn in each identification address BnN of the virtual partition K set in advance, for example, the position information of the combine A that has reached the central part in the identification address BnN is transmitted from the GPS satellite 600 described later to the GPS processing unit 128. If acquired (S100 YES), the position information acquired by the GPS processing unit 128 is supplied to the CPU 112 (S110). The CPU 112 that has acquired the position information generates control information for controlling the valve drive motor 761 to rotate forward, transmits the control information to the valve drive motor 761, and controls the inflow side on-off valve 719 via the valve drive motor 761. While opening the valve, the reciprocal opening / closing valve for closing the outflow side opening / closing valve 720 is driven (S120). Then, when the inflow side opening / closing valve 719 takes the inflow side valve opening posture P1 (reaching the fully open position) and the outflow side opening / closing valve 720 takes the outflow side valve closing posture P3 (reaching the fully closed position) (S130 YES), The forward rotation drive of the valve drive motor 761 is stopped (S140). Then, the sampling grain is temporarily stored in the temporary storage space 730 (S150).

  At the same time, the CPU 112 generates control information for driving and controlling the rotary drive motor 961, transmits the control information to the rotary drive motor 961, and controls the rotation of the large-diameter gear 932 via the rotary drive motor 961 (S160). . When the large-diameter gear 932 rotates by a certain angle, the pickup sensor 971 detects a certain rotation angle of the large-diameter gear 932, transmits detection information to the CPU 112, and when the CPU 112 acquires the detection information (S170 YES), the large-diameter gear 932 rotates. The rotation of the gear 932 is controlled to stop. As a result, the peripheral end opening surface 846 of the Nth sample storage chamber 845 is aligned with the sample inlet 836, and the sample storage chamber 845 is in a standby state (S180).

  When the storage amount detection sensor 732 detects that the storage amount of the sampling grain has reached a certain amount (YES in S190), the storage amount detection sensor 732 transmits detection information to the CPU 112. The CPU 112 that has acquired the detection information generates control information for performing reverse rotation drive control of the valve drive motor 761, transmits the control information to the valve drive motor 761, and controls the inflow side on-off valve 719 via the valve drive motor 761. While the valve is closed, the reciprocal opening / closing valve for opening the outflow side opening / closing valve 720 is driven (S200). Then, when the inflow side opening / closing valve 719 takes the inflow side valve closing posture P2 (reaches the fully closed position) and the outflow side opening / closing valve 720 takes the outflow side valve opening posture P4 (reaches the fully open position) (S210 YES), The reverse rotation drive of the valve drive motor 761 is stopped (S220). Then, the sampling kernel stored in the temporary storage space 730 flows down, and the sampling kernel is stored in the sample storage chamber 845 through the peripheral opening surface 846 aligned with the sample inlet 836 ( S230).

  When the limit amount detection sensor 737 detects a certain amount (the limit amount of sampling) of the first grain stored in the storage unit main body 20 (S240 YES), the function driving unit 716 receives the inflow side on-off valve 719 via the CPU 112. The state where the valve is closed is maintained. As a result, sampling is stopped. In addition, when the limit amount detection sensor 737 does not detect a certain amount of the first grain stored in the storage unit body 20 (a limit amount of sampling) (S240 NO), the above-described control operation is repeated, Sampling grains are sequentially stored in each sample storage chamber 845 of the storage container 810.

  Since the sampling operation is performed in this manner, the sampling grain is stored in each sample storage chamber 845 of the cartridge-type storage container 810, and thereafter the storage container 810 is removed as appropriate. Thus, the sampled grains in each sample storage chamber 845 can be post-processed to measure the internal quality.
