It is attached to the front part of the sprayer main body 1 so as to be rotatable around the central axis of the taking part 7a. When the hose reel 7 rotates in one direction (here, the clockwise direction in the figure), the hose 6 is wound around the hose reel 7, and the hose reel 7 rotates in the other direction (here, the counterclockwise direction in the figure). Then, the hose 6 is sent out from the hose reel 7. The engine 4 and the pump 5 are mounted on the sprayer main body 1 side by side at the rear of the hose reel 7.

  The hose guide 8 is disposed above the rear portion of the hose reel 7, and includes a guide main body 8a and a guide arm 8b provided continuously with the upper portion of the guide main body 8a.

  The guide body 8a reciprocates in the left-right direction in conjunction with the rotation of the hose reel 7. As the guide body 8a reciprocates, the hose 6 is uniformly wound on the hose reel 7. The guide arm 8b is attached to the upper part of the guide body 8a so as to be rotatable about the vertical axis, and the guide arm 8b is provided with a plurality of guide pulleys 8c. By rotating the guide arm 8b about the vertical axis, the hose 6 can be pulled out from the sprayer body 1 in all directions. Further, the hose 6 can be smoothly pulled out along the guide arm 8b by the guide pulley 8c.

  The guide main body 8a is provided with a hose feeding device 9 that pulls out the hose 6 wound around the hose reel 7 and feeds the hose 6 toward the guide arm 8b. The hose delivery device 9 has a hose delivery roller 9a and a pressing roller 9b that presses the hose 6 against the hose delivery roller 9a. The hose delivery device 9 can deliver the hose 6 by the rotation of the hose delivery roller 9a. .

  The pair of drive wheels 2, 2, pump 5, hose reel 7 and hose delivery roller 9 a are all driven by the power of the engine 4. As shown in FIG. 2, the power of the engine 4 is transmitted to the pump 5 via the belt B1 and the clutch C1, and the transmission / cutoff of the power can be switched by the clutch C1.

  The power of the engine 4 is transmitted to the power distributor 10 via the belt B2. The power transmitted to the power distributor 10 is further transmitted to the drive wheels 2 and 2, the hose reel 7 and the hose delivery roller 9 a.

  Power is transmitted from the power distributor 10 to the drive wheels 2 and 2 via the belt B3 and the clutch C2, and transmission / cutoff of power can be switched by the clutch C2. Power is transmitted from the power distributor 10 to the hose reel 7 via a take-up clutch C3 and a belt B4, and transmission / cut-off of power can be switched by the take-up clutch C3. Power is transmitted from the power distributor 10 to the hose delivery roller 9a via a delivery clutch C4 and a chain B5, and transmission / cutoff of power can be switched by the delivery clutch C4.

  Further, the power transmitted to the hose reel 7 is transmitted to the drive shaft 23 for moving the guide body 8a via the chain B6. Thereby, the guide body 8a reciprocates in the axial direction of the drive shaft 23 in conjunction with the rotation of the hose reel 7. B1 to B6 may be either a belt or a chain.

  The radio controlled power sprayer 100 includes a hose winding mechanism M1 that winds the hose 6 around the hose reel 7 of the sprayer main body 1, and a hose feeding mechanism M2 that feeds the hose 6 wound around the hose reel 7. The hose winding mechanism M1 includes the engine 4, the belt B2, the power distributor 10, the winding clutch C3, the belt B4, the hose reel 7, the belt B6, and the drive shaft 23. The hose delivery mechanism M2 includes the engine 4, the belt B2, the power distributor 10, the delivery clutch C4, the belt B5, the hose guide 8, and the hose delivery device 9.

  As shown in FIG. 1, the transmitter 40 includes a winding switch 42 for transmitting a winding signal for the hose 6 and a feeding switch 43 for transmitting a feeding signal for the hose 6 (the following description) The “switch” is abbreviated as “SW” in FIG. When the winding SW 42 is pushed by the worker X, a winding signal is transmitted to the receiver 30, the winding clutch C3 is turned on, and the power of the engine 4 is transmitted to the hose reel 7. When the delivery SW 43 is pushed by the worker X, a delivery signal is transmitted to the receiver 30, the delivery clutch C4 is turned on, and the power of the engine 4 is transmitted to the hose delivery roller 9a of the hose delivery device 9.

  The radio controlled power sprayer 100 of the present embodiment is provided with a hose take-up and feeding device A that receives a signal transmitted from the transmitter 40 and automatically controls the winding and sending of the hose 6. This hose take-up and delivery device A includes a receiver 30, a transmitter 40, and a hose take-up mechanism M1 and a hose feed mechanism M2 mounted on the sprayer main body 1, respectively.

  As illustrated in FIG. 3A, the receiver 30 includes a control unit 31 and a storage unit 32. When receiving the winding signal from the transmitter 40, the control unit 31 turns on the winding clutch C3. When receiving the delivery signal from the transmitter 40, the control unit 31 turns on the delivery clutch C4. The control unit 31 determines the time when the winding clutch C3 is on and the winding speed of the hose 6 by the hose winding mechanism M1, and the time when the feeding clutch C4 is on and the hose feeding mechanism M2. Based on the feeding speed of the hose 6, the feeding length Lh of the hose 6 may be calculated sequentially. The storage unit 32 stores the feeding length Lh calculated by the control unit 31 for each time.

  As illustrated in FIG. 3B, the transmitter 40 includes a GPS (Global Positioning System) receiver 44 that acquires position information of the transmitter 40, a control unit 45, and a storage unit 46. The GPS receiver 44 as transmitter position information acquisition means can acquire GPS position information of the transmitter 40 by receiving radio waves from a GPS satellite (not shown). When the winding SW 42 is pressed by the operator X, the control unit 45 transmits a winding signal to the control unit 31. When the delivery SW 43 is pushed by the worker X, the control unit 45 transmits a delivery signal to the control unit 31. Further, the control unit 45 performs a predetermined calculation and processing based on the position information of the transmitter 40 obtained by the GPS receiver 44, so that the take-up clutch is directed to the control unit 31 of the receiver 30 for a predetermined time. A winding signal or a sending signal is transmitted so that C3 or the sending clutch C4 is turned on. When the winding signal is transmitted by the control unit 45, the hose winding mechanism M1 operates. When the delivery signal is transmitted by the control unit 45, the hose delivery mechanism M2 is activated. The winding / feeding-out control by the control unit 45 is automatically executed even if the winding SW 42 or the feeding SW 43 is not pushed by the worker X. Details of the winding / feeding-out control by the control unit 45 will be described later.

  The storage unit 46 stores the position information of the sprayer main body 1 and the position information of the transmitter 40. More specifically, when the sprayer main body 1 is brought into the field and the position of the sprayer main body 1 is fixed, the main body position setting SW 41 is pushed by the worker X in the vicinity of the sprayer main body 1, thereby storing the storage unit. 46 memorize | stores the positional information (namely, positional information of the sprayer main body 1) of the transmitter 40 obtained from the GPS receiver 44. FIG. In addition, the storage unit 46 sequentially stores the position information of the transmitter 40 obtained by the GPS receiver 44. Furthermore, the memory | storage part 46 memorize | stores the various numerical values (distance L of the sprayer main body 1 and the transmitter 40, etc.) calculated by the control part 45 for every time.

  Next, with reference to FIG. 4, the winding and feeding control performed by the control unit 45 of the transmitter 40 will be described. First, the control part 45 acquires the positional information on the sprayer main body 1 (step S01). In this step S01, when the sprayer body 1 is brought into the field and the position of the sprayer body 1 is determined, the body position setting SW 41 is pressed once by the operator X at the place of the sprayer body 1, whereby GPS Position information of the transmitter 40 obtained from the receiving device 44 is stored in the storage unit 46 as position information of the sprayer main body 1. The control unit 45 acquires the position information of the sprayer main body 1 stored in the storage unit 46.

  Next, the control part 45 acquires the positional information on the transmitter 40 obtained from the GPS receiver 44 (step S02). In step S02, the control unit 45 acquires the position information of the transmitter 40 at regular time intervals (t seconds). Next, the control unit 45 calculates the distance L between the sprayer main body 1 and the transmitter 40 (step S03). In this step S03, the control unit 45 calculates the distance L between them by calculating the difference between the position of the transmitter 40 and the position of the sprayer main body 1 at regular time intervals (t seconds). The control unit 45 stores the calculated distance L in the storage unit 46 for each time (ie, corresponding to each time). The position of the transmitter 40 possessed by the worker X can be regarded as substantially the same as the position of the spray nozzle 6 a that is the tip of the hose 6. The calculation interval t seconds can be specifically 1 second or several seconds.

  Next, the control unit 45 calculates the difference between the latest distance L calculated in step S03 and the distance L ′ calculated t seconds ago (step S04). The controller 45 calculates the difference (temporal change) ΔL in the distance between the sprayer main body 1 and the transmitter 40 by calculating the difference between the distance L and the distance L ′. Here, the control unit 45 may calculate a difference between the latest distance L and the distance t × n seconds ago (n is a natural number). When the amount of change ΔL is a positive value, the transmitter 40 (that is, the worker X having the spray nozzle 6a of the hose 6) has moved in the direction away from the sprayer body 1 during t seconds. Means. When the amount of change ΔL is a negative value, the transmitter 40 (that is, the worker X having the spray nozzle 6a of the hose 6) has moved in the direction approaching the sprayer body 1 during t seconds. means.

  Next, the control unit 45 determines whether or not the change amount ΔL is positive and the absolute value of the change amount ΔL is greater than a certain value (step S05). This fixed value is a numerical value (threshold for sending out) related to the distance stored in advance in the storage unit 46, and may be zero or a positive value. When the change amount ΔL is positive and the absolute value thereof is larger than a certain value, the control unit 45 generates a hose delivery signal and transmits it to the control unit 31 of the receiver 30 (step S06). In step S06, a delivery signal is transmitted so that the delivery clutch C4 is turned on for Tf seconds. As a result, the hose delivery mechanism M2 is activated and the hose 6 is delivered over Tf seconds. Tf seconds, which is the ON period of the delivery clutch C4, can be determined based on the distance change ΔL and the delivery speed of the hose 6 in the hose delivery mechanism M2. Thereafter, the control unit 45 waits for t seconds (step S09). After waiting for t seconds, the control unit 45 returns to the process of step S02.

  On the other hand, if the distance change ΔL is equal to or less than zero in step S05, or if the absolute value is equal to or less than a certain value even if the change ΔL is positive, the controller 45 determines that the change ΔL is negative and It is determined whether or not the absolute value of the change amount ΔL is greater than a certain value (step S07). This fixed value is a numerical value (winding threshold) related to the distance stored in advance in the storage unit 46, and may be zero or a positive value. The constant value used in the determination in step S07 may be the same as or different from the constant value used in the determination in step S05. When the change amount ΔL is negative and the absolute value thereof is greater than a certain value, the control unit 45 generates a hose winding signal and transmits it to the control unit 31 of the receiver 30 (step S08). In step S08, a winding signal is transmitted so that the winding clutch C3 is turned on for Tr seconds. As a result, the hose winding mechanism M1 operates and the hose 6 is wound up for Tr seconds. Tr seconds, which is the ON period of the take-up clutch C3, can be determined based on the distance change ΔL and the take-up speed of the hose 6 in the hose take-up mechanism M1. Thereafter, the control unit 45 waits for t seconds (step S09). After waiting for t seconds, the control unit 45 returns to the process of step S02.

  On the other hand, if the distance change amount ΔL is greater than or equal to zero in step S07, or if the absolute value is less than a certain value even if the change amount ΔL is negative, the control unit 45 generates a sending signal or a winding signal. Without waiting for t seconds (step S09). After waiting for t seconds, the control unit 45 returns to the process of step S02.

  As described above, in the hose take-up and delivery device A, the hose take-up mechanism M1 or the hose feed mechanism M2 is operated based on the position information of the sprayer main body 1 and the position information of the transmitter 40. As shown in FIG. 5, the position of the transmitter 40 carried by the worker X is close to the position of the tip end portion (for example, the spray nozzle 6a) of the hose 6 held by the worker X, and these positions are close to each other. doing. Therefore, according to the position of the transmitter 40 based on the position of the sprayer main body 1, it is possible to recognize a situation where the hose 6 needs to be wound or sent out. For example, the position of the transmitter 40 indicated by a solid line in FIG. 5A is further away from the sprayer body 1 than the position of the transmitter 40 t seconds before indicated by the phantom line. Therefore, in this case, it may be necessary to send out the hose 6. Further, the position of the transmitter 40 indicated by the solid line in FIG. 5B is closer to the sprayer body 1 than the position of the transmitter 40 t seconds before indicated by the virtual line. Therefore, in this case, it may be necessary to wind up the hose 6. In the hose take-up and delivery apparatus A, the operator X takes up or sends out the hose 6 without manually operating the transmitter 40. Therefore, the troublesome operation of winding or feeding the hose 6 is reduced. Furthermore, since the frequency | count of operating the transmitter 40 with a pesticide-attached hand reduces, the cause of failure of the transmitter 40 is reducing.

  In the hose take-up and delivery device A, the control unit 45 activates the hose take-up mechanism M1 or the hose delivery mechanism M2 based on the temporal change ΔL of the distance L between the sprayer main body 1 and the transmitter 40. Therefore, if the distance between the sprayer main body 1 and the transmitter 40 is large (that is, if the transmitter 40 is away from the sprayer main body 1), the hose delivery mechanism M2 is operated to send out the hose 6, If the distance between the sprayer main body 1 and the transmitter 40 is small (that is, if the transmitter 40 is close to the sprayer main body 1), the control for operating the hose winding mechanism M1 to wind the hose 6 is performed. Is possible. Thus, the winding or sending out of the hose 6 is automatically adjusted according to the movement state of the worker X.

  Furthermore, when the position information of the sprayer main body 1 is acquired, the GPS receiver 44 of the transmitter 40 is used, so there is no need to provide a GPS receiver or the like on the sprayer main body 1 side.

  Next, another winding and feeding control performed by the control unit 45 of the transmitter 40 will be described with reference to FIG. The difference between the winding and feeding control shown in FIG. 6 and the winding and feeding control shown in FIG. 4 is that the feeding length Lh of the hose 6 is calculated instead of the process of step S04 for calculating the change amount ΔL of the distance L. Step S14, and Step S15 for calculating the difference between the distance L between the sprayer main body 1 and the transmitter 40 and the feeding length Lh of the hose 6. The processes in steps S11 to S13 are the same as the processes in steps S01 to S03 described above, and the processes in steps S16 to S20 are the same as the processes in steps S05 to S09 described above. In this winding / feeding-out control, the judgment criteria in steps S16 and S18 are different from the judgment criteria in steps S05 and S07 in the previous winding / feeding-out control.

  In step S <b> 14, the control unit 45 acquires the latest feeding length Lh of the hose 6 stored in the storage unit 32. This delivery length means the length of the hose 6 extending from the sprayer main body 1, and the control unit 31 of the receiver 30 determines the time during which the take-up clutch C3 is on and the hose take-up mechanism M1. Is calculated every fixed time (t seconds) based on the winding speed of the hose 6 and the time when the delivery clutch C4 is on and the delivery speed of the hose 6 by the hose delivery mechanism M2. In step S15, the control unit 45 calculates a difference ΔL between the latest distance L calculated in step S13 and the latest feeding length Lh calculated in step S14. In step S16, the control unit 45 determines whether or not the difference ΔL is larger than a certain value. This constant value is a numerical value (threshold for sending out) related to the distance stored in advance in the storage unit 46, and may be zero or a negative value. In step S18, the control unit 45 determines whether or not the difference ΔL is smaller than a certain value. This constant value is a numerical value (winding threshold) related to the distance stored in advance in the storage unit 46, and may be zero or a negative value. These constant values are different from the constant values in step S05 and step S07. Further, the fixed value used in the determination in step S18 may be the same as or different from the fixed value used in the determination in step S16. When the difference ΔL is zero, it means that the hose 6 is stretched without slack and extends linearly. If the difference ΔL is a negative value, it means that the hose 6 is somewhat slack.

  Even with such winding and feeding control, the hose 6 is wound or sent without the operator X manually operating the transmitter 40. Therefore, the troublesome operation of winding or feeding the hose 6 is reduced.

  The control unit 45 acquires the feeding length Lh of the hose 6, and based on the difference ΔL between the distance L between the sprayer body 1 and the transmitter 40 and the feeding length Lh of the hose 6, the hose winding mechanism M1 or The hose delivery mechanism M2 is activated. Depending on whether the feeding length Lh of the hose 6 is large or small with respect to the distance L between the sprayer main body 1 and the transmitter 40 (that is, how the hose 6 is tensioned or loosened), the hose winding mechanism M1 or the hose feeding mechanism M2 Therefore, the feeding length Lh of the hose 6 is automatically adjusted so as to be an appropriate length according to the distance L between the sprayer main body 1 and the transmitter 40.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. For example, a GPS receiver may be provided in the sprayer main body 1 and the position information of the sprayer main body 1 obtained from the GPS receiver may be used. In this case, it is not necessary to store the position of the sprayer body 1 in the storage unit 46 by pressing the body position setting SW 41 of the transmitter 40 at a place where the sprayer body 1 is located as in the above embodiment. Further, a transmission function may be provided in the receiver 30 on the sprayer body 1 side, and the position information of the sprayer body 1 may be transmitted from the receiver 30 to the transmitter 40. In this case, the control unit 45 can acquire the position information of the sprayer main body 1 at any time through the control unit 31. This is effective when the sprayer main body 1 moves.

  Not only when the memory | storage part 46 memorize | stores the positional information on the sprayer main body 1, but the memory | storage part 32 may memorize | store the positional information on the sprayer main body 1. FIG. In that case, the control unit 31 may transmit the position information of the sprayer main body 1 stored in the storage unit 32 to the transmitter 40. The transmitter position information acquisition means is not limited to the GPS receiver 44, and acquires the position information of the transmitter 40 based on the direction and distance from the control station (the position is fixed and known) to the transmitter 40. You may do.

  The winding and feeding control is not limited to being executed by the control unit 45 of the transmitter 40, and may be executed by the control unit 31 of the receiver 30. Another control unit that can communicate with the receiver 30 may be provided in a control station other than the receiver 30 and the transmitter 40.

  The transmitter 40 is not limited to being attached to the work clothes of the worker X, but may be carried by the worker X, for example, by being fixed to the spray nozzle 6a.

  In the said embodiment, although the case where the hose winding-out delivery apparatus A was applied to the radio controlled power sprayer 100 was demonstrated, if it is an agricultural working machine which has a hose reel which can wind up a hose freely, it will be in agricultural working machines other than a power spraying machine. The present invention can also be applied.
