  As shown in FIGS. 1 to 6, the fertilizer application device 4 is detachably disposed on the support frame 20 behind the seat 22 of the operation unit 21. That is, the fertilizer application device 4 is extended in one direction (left and right direction in this embodiment) to form a three-dimensional frame, and a plurality of (in this embodiment) the extension direction of the support frame portion 100 (in this embodiment). 6) A plurality of (six in this embodiment) communication units 110 each including the attached first to sixth feeding parts 64 to 69 and the upper end opening of each of the feeding parts 64 to 69. A hopper portion group 120 including the first to sixth hopper portions 70 to 75 and a plurality of (6 in the present embodiment) that extend in the front-rear direction and communicate with intermediate portions at the lower end openings of the feeding portions 64 to 69, respectively. Individual connection portions 130, a single pressurized air supply portion 140 supported by the support frame portion 100 and continuously connected to the front end portion of each connection portion 130, and a rear end portion of each connection portion 130. Multiple (6 in this example) fertilization ho And parts 150, and Feeding body drive motor 160 which drives feeding the feeding unit group 110 is supported by the supporting frame part 100, which comprises a.

  Each fertilization hose part 150 connects the base end part of the fertilization hose 76 to the rear end part of the connection part 130, and the fertilization hose is installed in the grooved body 80 attached to the left and right side middle positions of the floats 58, 59, 59. The distal end portion of 76 is inserted. The groove producing body 80 forms a groove for introducing fertilizer into the field, and fertilization is performed in the groove from the tip of the fertilizer hose 76 via the groove producing body 80.

  A single feed drive shaft 81 extending in the left-right direction is attached to the steering section group 110 in a transverse penetrating manner. As shown in FIG. 6, in each operation section (a fifth operation section 68 as an example thereof), fourth to sixth operation sections 67 to 69 of the right movable fertilizer section 9 described later are fed out. A roll-shaped feeding body 111 is concentrically attached to the right side steering shaft 81b to be moved. Each steering body 111 is coaxially attached to the left or right steering shafts 81a and 81b, and each steering body 111 is rotatably arranged in conjunction with the left and right steering shafts 81a and 81b. Each operating body 111 forms a large number of recesses 113 at intervals in the circumferential direction on the peripheral surface of the cylindrical main body 112 that is rotationally driven around an axis in one horizontal direction (left and right in this embodiment). Thus, the fertilizer as a granular material housed in the recess 113 located on the hopper side is fed out downward by a certain amount with the rotation of the main body 112 around the axis.

  Since the 1st-6th feeding parts 64-69 are constituted similarly, respectively, the composition is explained concretely below using the 5th feeding part 68 as a typical example. That is, as shown in FIG. 6, the 5th operation part 68 provides the supply side powder body detection means 310 in the upper part, provides the operation side powder body detection means 320 in the lower part, and has a partition body in the middle part. 340 is provided.

  The supply-side granular material detecting means 310 detects the presence or absence of fertilizer as the supply-side granular material supplied from the fifth hopper 74. Further, when a fertilizer bridge is generated in the fifth operation unit 68, the supply of fertilizer from the fifth hopper unit 74 to the fifth operation unit 68 is stopped, but such a state is also supplied on the supply side granular material detection unit 310. Will detect. And if the control means 170 acquires the detection information, the control means 170 will start the alerting means 330 mentioned later. Therefore, the operator who has been alerted by the alerting means 330 can quickly deal with it. That is, it is possible to quickly cope with a malfunction during the operation operation.

  On the other hand, the operation-side powder body detection means 320 detects the operation amount of the fertilizer as the operation-side powder body operated by the operation body 111. As these detection means 310 and 320, for example, photoelectric sensors that detect the presence or absence of powder particles (fertilizer in the present embodiment) in a non-contact manner can be employed. Then, an electrical signal is output according to the amount of light received by light incident or non-light incident on the powder detected by the photoelectric sensor, and the output information is transmitted to the control means 170 described later. That is, the supply-side granular material detection unit 310 and the discharge-side granular material detection unit 320 are connected to the input side of the control unit 170. At the output side of the control means 170, a warning means 330 disposed in the operation unit 21 is connected.

  The alerting means 330 is activated when the operation-side granular material detection means 320 detects an operation amount smaller than a preset fertilizer operation amount for a predetermined time (for example, 30 seconds) or more. To inform the operator of the necessity of cleaning. Any alerting means may be used as long as it can alert the operator. For example, an alarm sound that alerts the auditory sense, an alarm light that alerts the sense of vision, or a tactile sense. Those that cause alarm vibrations to be evoked can be adopted.

  The partition body 340 is formed in a brush shape, and the tip is in contact with the upper part of the outer peripheral surface of the feeding body 111. The partition 340 prevents the fertilizer supplied from the fifth hopper 74 from overflowing downward through the gap between the periphery of the feeding body 111 and the peripheral wall of the operation portion 68. Moreover, since the outer peripheral surface of the feeding body 111 and the partition body 340 move relative to each other when the feeding body 111 rotates in the rotation direction a, the fertilizer sticking out from the recess 113 is caused by the brush-like partition body 340. It is swept out of the recess 113. As a result, the amount of fertilizer taken into each recess 113 is made uniform.

  When the feeding body 111 rotates and the concave portion 113 faces downward, the fertilizer in the concave portion 113 is discharged downward. At this time, since the fertilizer is taken into each concave portion 113 by a predetermined amount, the fertilizer can be intermittently discharged (delivered) downward by a predetermined amount by rotating the feeding body 111.

  As shown in FIGS. 3 to 4, an input gear 82 is attached to the intermediate portion of the feed drive shaft 81 (right-hand drive shaft 81 b), and the input gear 82 is rotatably supported by the support frame portion 100. The intermediate gear 163 is engaged. The intermediate gear 163 is engaged with a drive gear 162 attached to the drive shaft 161 of the operating body drive motor 160.

  When the driven body drive motor 160 is driven, the rotational force of the drive shaft 161 is changed to the drive gear 162 attached thereto → the intermediate gear 163 → the input gear 82 → the feed drive shaft 81 (the right drive shaft 81b → the left drive shaft). By being transmitted to the output shaft 81a) → each control body 111, the control body 111 rotates so that the fertilizer is fed out from the corresponding control hole (not shown) by a certain amount.

  The first to sixth fertilization clutches 83 to 88 are provided in each of the operation portions 64 to 69, which are strut clutches that individually connect and disconnect the power transmission from the feeding drive shaft 81. The first fertilization clutch 83 and the second fertilization clutch 84 are interlocked and connected to a clutch operating body S described later via a seventh interlocking connection body 96. Further, the third fertilization clutch 85 is interlocked and connected to the clutch operating body S via the eighth interlocking connecting body 97. Further, the fourth fertilization clutch 86 is interlocked and connected to the clutch operating body S via the ninth interlocking connecting body 98. Further, the fifth fertilization clutch 87 and the sixth fertilization clutch 88 are interlocked and connected to the clutch operating body S via the tenth interlocking connecting body 99.

  As the 1st-4th interlocking connection bodies 96-99, what can transmit push-pull force, such as a push pull wire, is used, and each clutch is connected to each clutch via each interlocking connection body 96-99. 83-88 can be connected / disconnected.

  The pressure blast supply unit 140 includes a pressure blast supply pipe 141 formed in a cylindrical shape by extending in the left-right direction, and a pressure blast supply source 142 such as a blower continuously connected to the left end of the pressure blast supply pipe 141. It has. The pressurized air supply source 142 is supported at the left end of the support frame 100. The pressure blower supply pipe 141 is supported horizontally by the support frame unit 100 and communicated with the front end of each connection unit 130. And the pressure ventilation supply source 142 can supply pressure ventilation from the front end part of each connection part 130 through the pressure ventilation supply pipe 141.

  In the fertilizer applicator 4 configured as described above, the fertilizer having a grain shape is accommodated in the first to sixth hopper portions 70 to 75, and the fertilizer supplied from each of the hopper portions 70 to 75 is used as the driven body drive motor 160. The control members 111 of the control units 64 to 69 that are driven out to the maximum number of times are supplied to the connection units 130 by a certain amount. Then, a fixed amount of fertilizer is supplied through the fertilizer hose part 150 connected to the rear end part of each connection part 130 by supplying the pressurized air supply from the pressure air supply part 140 provided in communication with the front end part of each connection part 130. Is applied to the field.

  In the clutch operating body S, two cam bodies and a reduction gear (not shown) are coaxially attached to a support shaft, and a pinion gear attached to the drive shaft of the electric motor M is engaged with the reduction gear. By rotating the drive shaft of the electric motor M forward, each clutch is operated to be disengaged. Then, as shown in FIG. 7, the electric motor M is connected to the output side of the control means 170 described later and controlled to operate by the control means 170.

[Description of characteristic configuration of fertilizer application device according to this embodiment]
In the above configuration, the characteristic configuration of the fertilizer application device 4 according to the present embodiment is as follows. That is, as shown in FIG. 3 to FIG. 8, each operation body 111 that feeds a certain amount of powdered fertilizer is arranged in each operation section 64 to 69, and each operation body 111 is provided with each operation body 111. The operating body drive motor 160 for driving the motor is linked and connected. The manipulated body drive motor 160 is connected to the output side of the control means 170 that controls the drive operation, and can drive a cleaning means that cleans each of the manipulated bodies 111 via the control means 170. On the other hand, a cleaning operation means 180 for cleaning the cleaning means is connected to the input side of the control means 170.

  When the cleaning operation means 180 is cleaned, the cleaning means drives and controls the operating body drive motor 160 through the control means 170 at a rotational speed greater than the feeding rotational speed for a fixed time (for example, 10 seconds). Each of the operating bodies 111 is configured to rotate at a higher speed. The speed increasing speed here is, for example, a speed increased by 1.5 to 3 times the normal operating speed of each operating body 111. The cleaning means separates and disperses the fertilizer adhering in each recess 113 of each operation body 111 by centrifugal force generated in each operation body 111 rotated at a high speed. The inside of each recess 113 of the body 111 is cleaned. Further, when the cleaning means is operated, fertilizer is not supplied from the hopper parts 70 to 75 to the operation parts 64 to 69. For example, the inside of each hopper part 70-75 is made into an empty state, and it prevents a fertilizer from being detected by the supply side granular material detection means 310. FIG. By doing so, the cleaning in the respective concave portions 113 of the respective operation bodies 111 is performed steadily.

  As described above, each of the operation units 64 to 69 is provided with each of the roll-type operation units 111. Each operating body 111 has a recess 113 formed in the circumferential surface portion of a cylindrical main body 112 that is rotationally driven around a horizontal axis. And the fertilizer accommodated in the recessed part 113 of the opening state toward the upper direction located in the hopper part side was changed into the opening state toward the downward direction with the rotation of about 180 degrees around the axis line of the main body 112. By discharging from the inside of the recess 113, it is fed out by a predetermined amount right below.

  Moreover, the cleaning means can be driven via the cleaning operation means 180 only when the travel drive system of the travel device 1 is in a neutral state. That is, only when the travel drive system of the travel device 1 is in a neutral state, the cleaning operation means 180 is operated and the control means 170 controls the drive of the ejector drive motor 160 to a rotational speed greater than the feed rotational speed. It is possible.

  In the fertilizer applicator 4 configured as described above, the cleaning means can be driven by the operating body drive motor 160 via the control means 170 by performing the cleaning operation of the cleaning operation means 180. The inside of each recessed part 113 of the body 111 can be cleaned, and it can prevent staying with the fertilizer adhering to each recessed part 113 of each operation body 111. FIG. Therefore, the amount of fertilizer maneuvered by each maneuvering body 111 can be extended and the amount of application can be kept constant.

  When the cleaning operation means 180 is operated, the control body 170 is controlled to drive the drive body drive motor 160 at a rotational speed greater than the feed rotation speed for a certain period of time, so that each control body 111 is driven out. Therefore, the fertilizer adhering in the recessed part 113 of each operation body 111 is peeled off by centrifugal force. Therefore, the inside of each operation body 111 can be cleaned steadily. As a result, the amount of fertilizer maneuvered by each maneuvering body 111 can be extended and the amount of application can be kept constant. At this time, the operation body drive motor 160 that constitutes a part of the cleaning means is controlled to be driven for a certain period of time, that is, only when the operation bodies 111 are cleaned. The drive motor 160 can be provided with durability without applying an excessive load for a long time.

  In addition, the cleaning means can be driven via the cleaning operation means 180 only when the travel drive system of the travel apparatus 1 is in a neutral state, and when the travel apparatus 1 is driven to travel, the cleaning operation is performed. Even if the operator touches the means 180 by mistake, the cleaning means is not driven, so that the malfunction of the cleaning means can be prevented.

  That is, only when the traveling drive system of the traveling device 1 is in a neutral state, the cleaning operation means 180 can be operated and the control means can drive-control the driven body drive motor 160 at a rotational speed greater than the feeding rotational speed. When the traveling device 1 is driven to travel (this machine is moved), the operator driving motor 160 is not driven even if the operator accidentally touches the cleaning operation means 180. A malfunction of the drive motor 160 can be prevented.

  More specifically, a control program as an interlock mechanism is stored in the ROM of the control means 170 described later. Then, when the CPU of the control means 170 determines that the traveling device 1 is driven based on the detection result of the moving motion detection means 200, the CPU reads the control program into the RAM, and cleaning is performed according to this control program. A control operation for blocking the drive operation of the driven body drive motor 160 via the operation means 180 is executed. In other words, the CPU of the control means 170 controls the control body via the cleaning operation means 180 when the travel drive system of the travel device 1 is in a neutral state, that is, when the machine is in a movement stop state. The drive motor 160 is programmed so that it can be driven and controlled at a rotational speed larger than the feeding rotational speed. When the supply-side granular material detection unit 310 does not detect the fertilizer as the supply-side granular material supplied from each of the hopper portions 70 to 75, the feeding-unit driving motor 160 is turned on via the cleaning operation unit 180. It is programmed so that it can be driven and controlled at a rotational speed greater than the feeding rotational speed.

  Further, in this embodiment, when the position detection means 210 such as a limit switch detects that the speed change lever 6 (see FIGS. 1 and 2) provided in the driving unit 21 is operated to the neutral position, the detection information Is output to the control means 170. And the control means 170 acquires the detection information of the position detection means 210, and can drive-control the operation body drive motor 160 via the cleaning operation means 180. That is, the position detection unit 210 detects the speed change lever 6 operated to the neutral position, and in the case of the detection state, the control unit 170 can acquire the setting information from the cleaning operation unit 180 and drive the driven body. The motor 160 is driven and controlled at a rotational speed greater than the feeding rotational speed. In other words, when the position detection unit 210 does not detect the shift lever 6 operated to the neutral position, control is performed so as to prevent the drive operation of the driven body drive motor 160 via the cleaning operation unit 180. Yes. And when the supply side granular material detection means 310 does not detect the fertilizer as the supply side granular material supplied from each hopper part 70-75, the operating body drive motor 160 via the cleaning operation means 180 Control is performed to prevent the drive operation.

  The control means 170 is a computer device that includes a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and the like that are connected to each other via an internal bus. The CPU incorporates a timer, reads a control program stored in the ROM into the RAM, and executes a predetermined control operation according to the control program.

  On the input side of the control means 170, a cleaning operation means 180, a rotation speed detection means 190, a movement operation detection means 200, a position detection means 210, a supply side powder body detection means 310, and an operation side powder body detection means 320 are provided. Connection is made to obtain detection information from each means. Further, the control body 170 is connected to the control body driving motor 160, the electric motor M, and the alerting means 330, and generates control information based on the acquired detection information. Are output to the alerting means 330 to drive and control them.

  The cleaning operation means 180 is provided with a control ON / OFF switch 182, a cleaning rotation switch 183, and a volume switch 184 for increasing or decreasing a certain number of rotations on the front wall of the box-shaped casing body 181. . When the cleaning rotation switch 183 is turned on after the control ON / OFF switch 182 is turned on sequentially, the rotational speed per unit time of the pusher drive motor 160 is set to be constant, and the pusher drive is driven. The motor 160 is rotated for a predetermined time (for example, 10 seconds). The constant rotational speed can be set to a desired rotational speed by increasing or decreasing the volume switch 184 in advance by rotating the volume switch 184 in advance. At this time, the rotation speed can be set in an arbitrary range by the volume switch 184, but is preferably set in a range of 1.5 to 3 times the normal operation rotation speed. The cleaning operation unit 180 can transmit an operation signal to the control unit 170 by wire or wirelessly, and the operation of the cleaning operation unit 180 can be performed firmly in the vicinity of the driving unit 21 or the riding rice transplanter A.

  The rotational speed detection means 190 is a sensor that detects the rotational speed per unit time of the drive shaft 161 of the driven body drive motor 160 or the drive gear 162 attached to the drive shaft 161. For example, a rotary encoder can be adopted. it can.

  The movement operation detection means 200 is a sensor that detects the driving operation of the traveling device 1 during work or movement, and in this embodiment, the rotational speed of the front wheel shaft 11 or the rear wheel shaft 14 of the traveling device 1 is determined by, for example, rotary. Detection is performed by an encoder.

  In the riding rice transplanter A configured as described above, when the control unit 170 acquires information detected by the movement operation detection unit 200, the control unit 170 prevents the drive operation of the ejector drive motor 160 via the cleaning operation unit 180. Therefore, even when the operator accidentally touches the switch of the cleaning operation unit 180 or when the cleaning operation unit 180 malfunctions, the traveling device 1 is driven to travel (the body is moved). For example, during rice transplanting work or running on the road, the drive operation of the driven body drive motor 160 via the cleaning operation means 180 is blocked, so that fertilizer is not wasted.

  Furthermore, when the speed change lever 6 is in the neutral state in the travel drive system of the travel device 1, in the present embodiment, the rotational speed can be set by the cleaning operation means 180, otherwise, Since it is impossible to set the number of rotations by the cleaning operation means 180, when the traveling device 1 is driven to travel (the body is moved), the cleaning operation means 180 is erroneously operated and wasteful fertilization is performed. Can be prevented.

  Next, the control operation of the cleaning means when cleaning the operating body 111 will be described with reference to the flowchart of FIG.

  When the operation-side granular material detection means 320 detects an operation amount smaller than the preset operation amount of fertilizer (Yes in S400), the alerting means 330 is activated (S410). The operator who has been alerted appropriately stops the activation of the alerting means 330.

  After each hopper portion 70 to 75 is emptied by collecting fertilizer, the control ON / OFF switch 182 of the cleaning operation means 180 is turned ON (S420 Yes), and then the cleaning rotation switch 183 is turned ON. (S430 Yes), at that time, if the position detection means 210 detects the neutral position of the shift lever 6 and the control means 170 determines that the fertilizer is not detected by the supply side granular material detection means 310 according to the control program ( (S440 Yes), each operation body 111 is cleaned and rotated (S450).

When the cleaning rotation of each operation body 111 passes a certain time (for example, 10 seconds) (S460 Yes), the cleaning rotation of each operation body 111 is stopped (S470). After cleaning of each operation body 111 is completed, fertilizer is supplied into each hopper portion 70 to 75 that is in an empty state, and the fertilization work is continued.
By controlling the cleaning means in this way, the operator can clean each operation body 111 smoothly and firmly.
