Embodiment for Carrying out the Invention

[0014] An embodiment of the present invention will be described with reference to FIGS. 1 to 13.

[0015] In FIGS. 1 to 3, reference numeral 1 denotes an agricultural working machine (agricultural machine), and this agricultural working machine 1 is, for example, a crop processing machine for performing predetermined agricultural operations (processing) on the harvested crop W.

[0016] That is, the agricultural working machine 1 is a stationary onion processing machine that cuts off unnecessary parts of the harvested crop W, that is, the foliage and root parts, which are unnecessary parts of, for example, onions harvested from the field and dried in the open air.

[0017] The agricultural working machine (onion processing machine) 1 includes a machine body 2 having a connecting portion (not shown) detachably connected to a tractor, which is a traveling vehicle, on the front side, and a pair of left and right wheels 3 are provided on the rear side of the machine body 2.

[0018] Further, the agricultural working machine 1 includes a support portion 6 that can be rotated in the vertical direction and detachably supports a container 5, which is a crop storage body capable of storing a plurality of crops (a predetermined amount of onions to be processed) W, a drive portion 7 that rotates the support portion 6 in the vertical direction, a storage portion 8 in which the crop W supplied from the container 5 is temporarily stored, a transport portion 9 that transports the crop W discharged from the storage portion 8, and a sorting portion 10 for sorting the crop W.

[0019] Furthermore, the agricultural working machine 1 includes a detection portion 11 that detects the amount of the crop W in the storage portion 8, a control portion 12 that controls the drive portion 7 based on the detection by the detection portion 11, and an operation portion 13 that transmits operation information (signal) to the control portion 12.

[0020] The detection unit 11 consists of, for example, an optical distance sensor (remaining amount sensor) that detects the distance to the crops W in the storage unit 8. The control unit 12 has, for example, a timer function and appropriately controls the drive unit 7 as well as, for example, the drive source of the transport unit 9. The container 5 is, for example, a box-shaped mesh container with an outer rectangular parallelepiped shape and has an upper opening 5a for putting crops W into and taking them out of the container 5.

[0021] The support section 6 has a support body 21 that is roughly L-shaped in side view and detachably supports a box-shaped container 5 with an open top. The support body 21 is mounted on the upper ends of a pair of left and right frame sections 15 of the machine body 2 so as to be rotatable in the vertical direction about a pivot axis (pivot point) L1 in the left-right direction.

[0022] The support body 21 includes a bottom support portion 22 that supports the bottom surface of the container 5, a pair of left and right side support portions 23 that support the sides of the container 5 (the sides facing the frame portion of the machine body), and a cylindrical support frame portion 24 that is installed between the upper ends of these two side support portions 23. The support frame portion 24 is supported by both frame portions 15 of the machine body 2 so as to be rotatable about an axis portion (rotation center axis L1) 25.

[0023] Furthermore, an angle sensor (not shown), such as a potentiometer or pulse sensor, is provided near the shaft portion 25 of the support body 21 to detect the rotation angle of the support portion 6. Therefore, the control unit 12 can recognize the position of the support portion 6 (the height position of the support body) based on the detection information from the angle sensor.

[0024] Furthermore, plate-shaped restricting bodies 20 are attached to both the left and right ends of the bottom support portion 22 of the support body 21 to restrict the lateral movement of the container 5. In addition, a container retaining body 26 is rotatably attached to the upper end of the side support portion 23 of the support body 21 to press down on and support the top surface of the container 5. In other words, this container retaining body 26 is provided on the upper end of the support body 21 so as to be rotatable in the vertical direction about a pivot axis (rotation fulcrum) L2 in the left-right direction (see Figure 4).

[0025] As shown in Figure 4, the container retainer 26 has a pair of left and right retaining parts 27, and these two retaining parts 27 are connected by a rod-shaped connecting part 28. Contact parts 29 are provided at two locations on the left and right of the connecting part 28, which come into contact with a restricting member 17 attached to the mounting frame part 16 of the machine body 2. The downward rotation of the container retainer 26 is restricted by the contact between the contact parts 29 and the restricting member 17.

[0026] The drive unit 7 has a pair of retractable left and right cylinders (e.g., hydraulic cylinders) 31 that are spaced apart from each other. Each cylinder 31 has a cylinder body 32 and a rod 33 that moves in and out of the cylinder body 32. The base end of the cylinder body 32 is rotatably attached to a cylinder mounting portion 36 of the machine body 2. The tip of the rod 33 is rotatably attached to a cylinder mounting portion 37 of the support 21.

[0027] Then, the extension of the cylinder 31 causes the support portion 6 to rotate in one direction, upward (the supply direction, which is counterclockwise in Figure 1), and the contraction of the cylinder 31 causes the support portion 6 to rotate in the other direction, downward (the return direction, which is clockwise in Figure 1).

[0028] In the example shown in Figure 1, the rotation angle α of the support part 6 (the rotation angle from the lower limit position to the upper limit position) is approximately 135 degrees. Furthermore, the supply unit (supply device) 40 is configured by the support part 6 that supports the container (supply container) 5 containing the agricultural products W, and the drive unit 7 that drives the support part 6, to supply the agricultural products W from the container 5 into the storage unit 8.

[0029] The storage unit 8 has a corrugated conveyor 41 at its bottom, which is an inclined conveying means that conveys the agricultural products (onions before processing) W supplied by the supply unit 40 in the conveying direction (the direction of the arrow shown in Figure 3, which is inclined from front to back and lower to higher) and discharges (sends) them to the conveying start end of the conveying unit 9.

[0030] Furthermore, the storage section 8 includes a pair of inclined left and right guide plates 42 that guide the crops W onto the conveying surface 45 of the corrugated conveyor 41, and an inclined restricting plate 43 that restricts the crops W on the conveying surface 45 of the corrugated conveyor 41 from rolling and moving in the opposite direction of conveying due to their own weight.

[0031] The corrugated conveyor 41 has a corrugated endless belt 46, which is stretched over a plurality of sprockets 47. The upper forward surface of the endless belt 46 is an inclined conveying surface 45 that conveys agricultural products W in the conveying direction.

[0032] Furthermore, above the corrugated conveyor 41, a stopper mechanism 44 is positioned to prevent the container 5 from falling by contacting the top surface of the container 5 when the support part 6 moves to its upper limit position. The stopper mechanism 44 has a rotatable stopper 48 that contacts the top surface of the container 5, and this stopper 48 is elastically supported by a buffer gas spring 49.

[0033] The conveying unit 9 is a conveying and cutting unit that receives and conveys agricultural products W discharged from the corrugated conveyor 41 of the storage unit 8, and cuts off the unnecessary parts of the agricultural products W, namely the stems, leaves, and roots, during the conveying process.

[0034] In other words, this conveying unit 9 transports the crop W, which is an onion, while cutting its stems, leaves, and roots. For example, as shown in Figure 1, it includes a conveying chute 51, a conveying roller 52, a lifting conveyor 53, a vibrating conveyor 55 having a vibration generating unit 54, a cutting conveyor (stem and leaf cutting means) 57 having a stem and leaf cutting unit 56, a conveying chute 58, a tapping conveyor (root cutting means) 59 for cutting the roots, and a lift conveyor 60 for lifting and transporting the crop (onion) W after the cutting process.

[0035] Then, when the agricultural products W discharged from the storage section 8 and supplied onto the conveying section 9 are conveyed by the conveying rollers 52, the lifting conveyor 53, and the vibrating conveyor 55, impurities such as pebbles and clumps of soil are removed, and tangled leaves are loosened and separated individually.

[0036] Afterward, each crop W, separated from the others, has its stems and leaves cut by a cutting conveyor 57 and its roots cut by a tapping conveyor 59, before being lifted and transported by a lift conveyor 60 to the sorting section 10 for the next process. The stems, leaves, and roots that have been cut and removed from the spherical body of the crop W are transported to the rear by an output conveyor 50 located at the bottom of the machine 2 and are discharged from the rear end of the machine 2.

[0037] The sorting unit 10 has a sorting conveyor belt 61 for transporting the crops W after the cutting process. The worker on step 62 then performs a sorting operation to separate the crops W on the conveyor belt 61 into good products and defective products.

[0038] As a result of sorting, good quality produce (onions within specifications) W are transported via a good quality chute 63 and a slide conveyor 64 and stored in a good quality container 65, while defective produce (onions outside specifications) W are transported via a defective product chute 66 and stored in a defective product container 67. Above the good quality chute 63, there is an operating unit 13 that is operated by a worker standing on a step 62.

[0039] The operation unit 13 includes, for example, an operating lever 71 for raising and lowering, a changeover switch (mode switching means) 72 for turning automatic control on and off, an indicator lamp 73 that lights up in automatic control mode (when the changeover switch is "on") and turns off in manual control mode (when the changeover switch is "off"), an emergency stop switch 74, a start switch 75 for starting the conveyor, and a selection switch (rotary switch) 76 which is a selection means for selecting an operation pattern.

[0040] The selection switch 76 is a pattern selection operation unit for selecting the operation pattern of the support unit 6 according to the state of the crop W (such as the moisture and dryness of the onion stems and leaves). In other words, the operation pattern of the support unit 6, based on the control of the control unit 12, can be arbitrarily (freely) selected from a plurality of preset operation patterns (for example, seven) according to the state of the crop W by operating the selection switch 76.

[0041] Here, an example of an operation pattern selectable by the selection switch 76 is shown in Figure 5(b), but it is not limited to this pattern.

[0042] For example, the operation patterns may include "2 seconds of upward movement, 0 seconds of downward movement" (when the stem and leaves are dry) or "2 seconds of upward movement, 1 second of downward movement" (when the stem and leaves are wet). Also, the number of oscillations at the upper limit position may be "3" or more, and the number of seconds of downward movement (= upward movement) at that time may be arbitrary, such as "1.0 second", "1.5 seconds", or "2 seconds" (however, 2 seconds or less is preferable).

[0043] Although the operation unit 13 shown in Figure 5 has multiple pre-set operation patterns, it may be configured to allow the operation patterns of the support unit 6 to be changed by providing, for example, a means for changing patterns (switches, buttons, etc.). Alternatively, the control unit 12 may be remotely controlled using a remote control (remote control unit) that has the same levers and switches as the operation unit 13.

[0044] Next, following the flowchart shown in Figure 6, and referring to Figures 7 through 13, the operation of the support unit 6 of the agricultural implement 1 (automatic crop supply operation) will be explained.

[0045] When automatically supplying the unprocessed crop (onions) W from container 5 to storage unit 8, the operator in step 62 selects an operation pattern (for example, operation pattern 5, "rise for 1.5 seconds, descend for 0.5 seconds, vibrate twice") using the selection switch 76 on the control unit 13, then switches the changeover switch 72 to "on," and then presses and holds the control lever 71 to the "rise" side to signal the start of supply (step 1).

[0046] Furthermore, the worker who uses a tractor or lift to place the container 5 containing the agricultural products W onto the support section 6 at the lower limit position may also use a remote control to issue a command to start supplying.

[0047] Then, when the supply start is instructed, the control unit 12 controls the cylinder 31 of the drive unit 7 to perform an operation (first operation) at least once in which the support unit 6 rotates upward from the lower limit position to a predetermined position (a predetermined intermediate position) lower than the upper limit position, i.e., a preset initial height position, and then, when the amount of crop W in the storage unit 8 decreases, the support unit 6 rotates upward for a preset first set time, which is a preset first set value, and then rotates downward for a preset second set time, which is shorter than the first set time (basically a different time from the first set time, but it is also possible to set it to the same time (including approximately the same time)).

[0048] Specifically, as shown in Figures 7 and 8, first, the support part 6 that supports the container 5 containing the agricultural products W rotates upward (rises) from the lower limit position to the initial height position around the pivot axis L1, together with the container 5 (Step 2). During this upward rotation, the container 5 moves by the amount of the gap 80 and is supported by the side support part 23 of the support body 21, as well as by the container retaining body 26.

[0049] Then, the agricultural products W inside the container 5 fall out of the top opening 5a into the storage section 8 and are supplied onto the corrugated conveyor 41, which then transports the supplied agricultural products W toward the transport section 9. As a result, the amount (remaining amount) of agricultural products W inside the storage section 8 gradually decreases, as shown in Figure 9.

[0050] Then, based on the detection by the detection unit 11, the control unit 12 determines whether the amount of agricultural products W in the storage unit 8 is less than or equal to a set amount (step 3). If it determines that the remaining amount is less than or equal to the set amount, the support unit 6 rotates upward for a first set time (for example, "1.5 seconds" in operation pattern 5) as shown in Figure 10 (step 4), and immediately afterward rotates downward for a second set time shorter than the first set time (for example, "0.5 seconds" in operation pattern 5) (step 5). At this time, the top opening 5a of the container 5 will be facing diagonally downward beyond the vertical plane, but since the container 5 is supported by the container retainer 26, it will not fall from the support 21.

[0051] This upward and downward movement of the support section 6 (up for X seconds + down for Y seconds) primarily releases the entanglement of crops W within the container 5 (a state in which the stems and leaves of onions are intertwined and entangled with each other). This prevents multiple crops W with damp, entangled stems and leaves from falling into the storage section 8 as a large clump. This upward and downward movement is repeated until the support section 6 reaches a position near a preset upper limit.

[0052] Next, the control unit 12 determines whether the support unit 6 has reached the upper limit position based on the detection by the angle sensor (step 6). If it determines that the support unit 6 has reached the upper limit position shown in Figure 11, it determines whether the amount of agricultural products W in the storage unit 8 is below the set amount based on the detection by the detection unit 11 (step 7). If it is determined in step 6 that the support unit 6 has not reached the upper limit position, the process returns to step 3 and the upward and downward movement is repeated.

[0053] Then, when it is determined that the amount of crops W in the storage section 8 has fallen below the set amount, the support section 6 rotates upward from near the upper limit position (just before the upper limit position) to the upper limit position, as shown in Figure 12 (step 8). At this time, the top surface of the container 5 comes into contact with the stopper 48 of the stopper means 44.

[0054] Here, the control unit 12 controls the cylinder 31 of the drive unit 7 so that, after the support unit 6 rotates upward from near the upper limit position to a preset upper limit position, and when the amount of crop W in the storage unit 8 decreases, the support unit 6 rotates downward for a preset time (hereinafter sometimes referred to as the "third setting time") which is a preset value (third setting value), and then rotates upward for the same time (including approximately the same time) which is the same value as the setting time, at least once using the timer function (second operation).

[0055] Specifically, with the support unit 6 in the upper limit position, the control unit 12 determines whether the remaining amount of agricultural products W in the storage unit 8 is below a set amount based on detection information from the detection unit 11 (step 9). If it determines that the remaining amount is below the set amount, the support unit 6 rotates downward for a third set time (e.g., "1.0 second") as shown in Figure 13 (step 10), and immediately afterward rotates upward for the same third set time (e.g., "1.0 second") (step 11).

[0056] In other words, when the remaining amount in the storage section 8 falls below a set amount, the support section 6 performs a downward and upward movement (downward for Z seconds + upward for Z seconds), i.e., a oscillating movement, based on the control of the cylinder 31 by the control unit 12.

[0057] Next, the control unit 12 determines whether the number of oscillations of the support unit 6 has reached a set number (step 12). If it determines that the number has reached the set number, the support unit 6 rotates downward (descends) from the upper limit position to a preset lower limit position (step 13). During this downward rotation, the container holder 26 rotates downward together with the container 5, but its downward rotation is restricted and stopped when the contact portion 29 comes into contact with the regulating member 17. The empty container is then lowered from the support unit 6, which has returned to the lower limit position, and the next supply container is placed on top, and the same operation is performed.

[0058] Furthermore, if in step 12 it is determined that the number of oscillations of the support part 6 has not reached the set number (for example, "2 times"), the process returns to step 10 and repeats the downward and upward movement (oscillating movement).

[0059] This downward and upward movement of the support part 6 (downward for Z seconds + upward for Z seconds) primarily releases the hooked engagement between the crops W inside the container 5 and the mesh part of the container 5 (a state in which the stems and leaves of the onions are entangled and hooked with the mesh part of the container), thereby preventing any crops W that should be supplied to the storage part 8 from remaining inside the container 5. This downward and upward movement, which is the oscillating motion, is repeated until a predetermined number of times (multiple times are preferable) is reached.

[0060] Furthermore, if the operating lever 71 is pressed and held to the "down" position before the swinging motion, the support unit (supply stage) 6 will descend to its lower limit position. Also, while the support unit 6 is rising, pressing the operating lever 71 to the "down" position switches from automatic control mode to manual control mode, and while the support unit 6 is descending, pressing the operating lever 71 to the "up" position switches from automatic control mode to manual control mode. In manual control mode, the operator can move the support unit 6 up and down arbitrarily within the range from the lower limit position to the upper limit position by operating the operating lever 71.

[0061] Furthermore, according to the above-described agricultural machine 1, a support part 6 is provided on the machine body 2 so as to be rotatable in the vertical direction about a pivot axis L1 and supports the container 5, a drive part 7 rotates the support part 6 in the vertical direction, and a control unit 12 controls the drive part 7. The control unit 12 controls the drive unit 7 so that the support part 6 performs predetermined operations (operations in the vertical direction) to release the hooked engagement of agricultural products W in the container 5, that is, for example, the first and second operations described above. In this way, for example, hooked engagements between agricultural products W in the container 5 and hooked engagements between agricultural products W and the container 5 can be released, and agricultural products W can be appropriately supplied into the storage part 8.

[0062] Therefore, for example, it is possible to prevent crops W from being damaged when a large clump of entangled stems and leaves is supplied into the storage section 8, and crops W with entangled stems and leaves will not remain in the container 5, thereby improving work efficiency.

[0063] Furthermore, since the operation pattern (up and down rotation pattern) of the support unit 6 controlled by the control unit 12 can be selected from multiple operation patterns according to the state of the crops W inside the container, it can respond to the state of the crops W, thereby enabling more appropriate supply of the crops W.

[0064] Furthermore, agricultural machinery is not limited to onion processing machines that cut and process the stems and leaves of onions, which are agricultural crops; for example, it may also be machinery used to perform agricultural work (processing) on ​​crops other than onions.

[0065] Furthermore, the support unit is not limited to performing both the first and second operations based on the control of the drive unit by the control unit; for example, it may perform only one of the first or second operations.

[0066] Furthermore, the control unit may be, for example, a touch panel or a mobile device with a pre-installed application.

[0067] Alternatively, the control unit may control the operation of the support unit based on the operator's voice acquired by the voice acquisition unit. For example, the control unit may select an operation pattern for the support unit from among multiple operation patterns based on the operator's voice.

[0068] Furthermore, the support unit (wrist device) that supports the crop storage unit is not limited to one that only rotates vertically (up and down rotation) relative to the machine body, but only needs to rotate vertically at least. For example, it may be able to rotate vertically and also be able to move up and down relative to the machine body, or it may be able to rotate vertically and horizontally, etc.

[0069] Furthermore, the control unit is not limited to controlling the drive unit using a timer function (rotation time information) to perform actions such as the support unit rotating upward for a first set time and then rotating downward for a second set time shorter than the first set time, or the support unit rotating downward for a third set time and then rotating upward for the same amount of time as the third set time. For example, it may also control the drive unit using detection information from an angle sensor (rotation angle information) to perform actions such as the support unit rotating upward by a first set angle and then rotating downward by a second set angle smaller than the first set angle, or the support unit rotating downward by a third set angle and then rotating upward by the same amount of time as the third set angle.

[0070] Furthermore, the control unit may, for example, use detection information (height information) from a height position sensor to control the drive unit so that the support unit rotates upward by a first set height (which may be a set distance or set position, etc.) and then rotates downward by a second set height lower than the first set height, or rotates downward by a third set height and then rotates upward by the same height as the third set height.
