  The chemical liquid suction / discharge path of the spray circuit 12 includes a low pressure water intake path 35 extending from the chemical liquid tank 5 to the pump 8 and a high pressure water discharge path 37 extending from the pump 8 to the spray booms 9a and 9b via the flow rate control valve 36. Are connected by a hose or the like. 9c is an extension boom, and is configured to be connected to the spreading boom 9b, and is configured to be attached / detached in accordance with a working state. If the extension boom 9c is always connected, spraying is performed by opening the cock 9d when spraying using the extension boom 9c, and spraying is performed by closing the cock 9d when not using the extension boom 9c. It may not be possible.

  The high-pressure water discharge path 37 is provided with a spillage return path 40 having a safety valve 38 for releasing a liquid pressure higher than a certain pressure, and can be returned to the chemical liquid tank 5. In addition, a stirring path 41 is communicated with the bottom of the chemical liquid tank 5 so that a part of the chemical liquid is constantly ejected and reduced into the tank to agitate the chemical liquid in the chemical liquid tank 5. In the high-pressure water discharge path 37 between the flow control valve 36 and the spray cocks C1, C2, C3 to the booms 9a, 9b, a pressure sensor 42 for detecting the fluid pressure and a first flow rate sensor 43 for detecting the flow rate are provided. Provided. The opening degree of the flow control valve 36 is controlled by a control motor. Reference numeral 39 denotes an air chamber.

  The chemical liquid flows from the spray cocks C1, C2, C3 to the left side boom 9b, the center boom 9a, and the right side boom 9b are connected by pipes D1, D2, D3.

  In addition, a suction filter 44 is provided between the chemical liquid tank 5 and the pump 8 in the low-pressure water absorption path 35, and a flow rate in the water absorption path is detected between the suction filter 44 and the pump 8. A two-flow sensor 45 is provided.

  FIG. 5 is a plan view of the riding type control machine, showing a state in which the spreading boom 9 is expanded. As described above, the chemical liquid tank 5 is usually composed of one piece, but in this embodiment, it is composed of a left chemical liquid tank 50, a right chemical liquid tank 51, and a central chemical liquid tank 52. When such three chemical liquid tanks 50, 51, 52 are used, it is a case where work is performed using the spreading boom 9 (center boom 9a, left and right spreading boom (side boom) 9b, 9b) in front of the machine body. . Reference numeral 78 denotes a carrier. Reference numeral 79 denotes a support frame on the rear side of the central chemical tank 52.

  FIG. 6 shows a configuration in which the central chemical liquid tank 52 is removed and a middle tillage weeder 53 is equipped. FIG. 7 is a rear view of FIG. 6, that is, a rear view when the middle tiller 53 is attached. Then, when working with the middle plowing weeder 53, the left and right spraying booms (side booms) 9b, 9b are removed. Basically, the remaining center boom 9a is not used, but the removal work is troublesome, so it is in a mounted state. A spraying device 54 is configured to spray the herbicide from the nozzle 55. The herbicide sprayed from the nozzle 55 is stored in the left and right chemical tanks 50 and 51.

  Since the middle plowing weeder 53 has a well-known configuration, a detailed description is omitted, but a plate 53b is provided around the rotation shaft 53a, and the upper side of the rotation direction of the plate 53b has a blade shape. Accordingly, when the plate 53b rotates, the grass is scraped off from the root or with the soil. And it is the structure by which a chemical | medical solution is spread from the spreading | diffusion apparatus 54. FIG.

  Thus, by removing the central chemical tank 52, the middle tillage weeder 53 can be easily attached. And when the huge chemical tank 5 is mounted as in the prior art, the huge chemical tank 5 must be removed once and the left and right chemical tanks 50 and 51 must be attached, which is very troublesome. However, such a problem can be prevented.

  The independent left and right chemical liquid tanks 50 and 51 and the central chemical liquid tank 52 are arranged in a U shape in plan view. That is, the left and right chemical liquid tanks 50 and 51 are configured to extend to the limit lines 50a and 51a that can be mounted. The left limit line 50a is in a range (up to step 56) in which the operator can get on and off. The limit line 51a on the right side extends to the operation panel 20. Thereby, the capacity | capacitance of the chemical | medical solution tanks 50 and 51 on either side increases. Since the central chemical tank 52 is mounted on the rear part of the machine body, it is easy to attach and detach the chemical tank 52 from the rear of the machine body.

The operation panel 20 may be provided on the machine body side or may be provided on either one of the left and right chemical liquid tanks 50 and 51.
Further, the capacity of the central chemical liquid tank 52 is configured to be larger than the capacity of the left and right chemical liquid tanks 50 and 51. Since the amount of the herbicide used for the operation of the middle tillage weeder 53 is not large, the capacity of the left and right chemical tanks 50 and 51 may not be large. When the central chemical tank 52 is mounted, the amount of chemical required to use the spray boom 9 in front of the machine body is increased. For this purpose, the amount of the central chemical tank 52 is increased.

  FIG. 8 shows the positional relationship between the left and right chemical liquid tanks 50 and 51 and the central chemical liquid tank 52. A part of the chemical liquid tank 52 and a part of the left and right chemical liquid tanks 50 and 51 have an overlapping portion F. Specifically, a part of the central chemical liquid tank 52 is placed above part of the left and right chemical liquid tanks 50 and 51. Thereby, the capacity | capacitance of the center chemical | medical solution tank 52 comes to increase. The chemical solution tank 52 on the right side of the arrow indicates a situation where the chemical solution tank 52 is dislocated to the rear of the machine body.

  Further, the overlapping portion F of the left and right chemical liquid tanks 50 and 51 is formed in a flat shape, and further, a predetermined amount in the flat portion of the left and right chemical liquid tanks 50 and 51 is larger than the upper surface portions 50b and 51b of the left and right chemical liquid tanks 50 and 51. (Several centimeters) Down. As a result, when a part of the central chemical liquid tank 52 is placed on the flat portion, the central chemical liquid tank 52 becomes stable.

  Also, left and right protrusions 64a and 64a are provided in the central chemical liquid tank 52, a concave portion 65b is provided in the left chemical liquid tank 50, and a concave portion 65c is provided in the right chemical liquid tank 51. The left and right protrusions 64a and 64a of the central chemical liquid tank 52 are configured to fit into the concave portion 65b of the left chemical liquid tank 50 and the concave portion 65c of the right chemical liquid tank 51, respectively. As a result, the chemical liquid tank 52 at the center can be further prevented from floating and the tank itself can be stabilized.

  FIG. 9 shows the piping relationship between the left and right chemical liquid tanks 50 and 51 and the central chemical liquid tank 52. The chemical liquid tank 52 at the center and the chemical liquid tank 50 on the left side are connected to each other by a pipe 57 below. The left chemical tank 50 and the right chemical tank 51 are connected to each other by a pipe 58 below the chemical tank 50. As a result, the amount of the chemical solution is reduced uniformly for the three chemical solution tanks 50, 51, and 52, so that the number of water absorption points may be one, and the number of times of water absorption is reduced to improve the work efficiency. 61, 62, and 63 are water absorption lids of the chemical liquid tanks 50, 51, and 52, respectively.

  When the pump 8 provided below the driver's seat 6 is driven, the chemical liquid is sucked from the outlet 60 under the right chemical liquid tank 51 through the pipe 59 to the pump 8. Thereafter, water is distributed from the pipe 59 to the spray cocks C1, C2, and C3 of the operation panel 20, and further, the left side boom 9b and the center boom 9a are passed through the pipes D1, D2, and D3 from the spray cocks C1, C2, and C3, respectively. The chemical solution is distributed to the right side boom 9b.

  If the pipe 57 connecting the central chemical tank 52 and the left chemical tank 50 is removed, the left and right chemical tanks 50 and 51 and the central chemical tank 52 can be used independently. In this case, when the pipe 59 is connected to the right chemical tank 51, the chemical liquid in the left and right chemical tanks 50 and 51 can be used. When the pipe 59 is connected to the central chemical tank 52, the chemical liquid in the central chemical tank 52 can be used. Of course, it goes without saying that the part where the piping is removed is covered.

  As a result, if the left and right chemical liquid tanks 50 and 51 are used in the case of a small amount spraying, and the central chemical liquid tank 52 is used in the case of a large amount spraying, recovery of the remaining chemical liquid is facilitated in a short time. Further, the type of the chemical solution in the left and right chemical solution tanks 50 and 51 and the type of the chemical solution in the central chemical solution tank 52 are made different, so that the type of the chemical solution can be easily changed during the work or in another field.

  FIG. 10 is an image diagram of attaching and detaching the middle tillage weeder 53. A spraying device 54 and a pipe 66 are provided on the middle plowing weeder 53 side. The spraying device 54 includes a left spraying device 54a, a middle spraying device 54b, and a right spraying device 54c. The spraying device 54 includes a plurality of pipes 66a, 66b, and 66c connected to the plurality of spraying devices. A plurality of couplers 67a, 67b, 67c for connecting to the plurality of pipes 66a, 66b, 66c are permanently installed on the machine body side. And it is the structure which has also provided the cock 68 spread | spread on the middle plowing weeder 53 side.

  As a result, when working with the intermediate tiller 53, the cock 68 and the couplers 67a, 67b, 67c are already provided, so the cock 68 and the couplers 67a, 67b, 67c can be attached and detached. Therefore, the middle tillage weeder 53 can be used in a short time.

  FIG. 11 is a side view of the spray boom 9 provided at the front of the self-propelled control machine. A link bracket 69 is provided on the machine body side, and the upper link 70 and the lower link 71 are loosely fitted to the link bracket 69 toward the front. And the front end part of the upper link 70 and the lower link 71 is loosely connected by the boom frame 72, and has a four-point link configuration.

  As described above, the center boom 9a is attached to the boom frame 72. A plurality of nozzles 11 are provided on the center boom 9a. The left and right side booms 9b, 9b are connected to the left and right sides of the center boom 9a, but are not shown in the drawing.

  When the length of the upper link 70 is L and the length of the lower link 71 is L0, the length relationship is (L <L0). As a result, the nozzle 11 attached to the center boom 9a is inclined P degrees toward the front with respect to the vertical direction. For this reason, the angle θ formed by the vector direction of the chemical liquid sprayed from the nozzle 11 and the ground is smaller than 90 degrees.

  For this reason, as shown in FIG. 11, the chemical liquid sprayed from the nozzle 11 is sprayed along a locus M. That is, the chemical solution once comes into contact with the ground and then comes into contact with the back side of the leaf. Conventionally, since the spray of the chemical liquid was in the vertical direction, it was difficult for the chemical liquid to hit the back side of the leaf, but such a problem can be prevented.

  As a result, the chemical solution is efficiently applied to the back side of the leaf of the crop, so that insects and the like lurking on the back side of the leaf can be easily controlled. Of course, on the front side of the leaf, the chemical solution floating in the air in the form of a mist falls and hits naturally, so it is possible to disinfect the front side of the leaf as usual.

  Further, by lowering the above-described four-point link mechanism, the position of the nozzle 11 in the vertical direction can be changed to change the spray position. Even in such a case, the trajectory M of the chemical liquid sprayed from the nozzle 11 is configured to move forward, so that the chemical liquid spraying to the back side of the leaf is not delayed. Reference numeral 73 denotes a lifting cylinder.

  The configuration of FIG. 12 is provided with two holes N1 and N2 in the front portion of the upper link 70, and the connection point between the boom frame 72 and the upper link 70 can be selected as either the hole N1 or the hole N2. Are connected. Thereby, since the value of the forward tilt angle P of the nozzle 11 with respect to the vertical direction changes, the spray angle of the chemical liquid sprayed from the nozzle 11 also tilts, and the adaptability according to the conditions of the crops is improved. It becomes like this.

  The configuration of FIG. 13 is a configuration in which the length L0 of the lower link 71 is made longer than the length L of the upper link 70 (L> L0). As a result, the nozzle 11 is inclined P2 degrees toward the rear with respect to the vertical direction. The trajectory M1 of the chemical sprayed from the nozzle 11 is symmetric with the trajectory M in FIG. 11 with respect to the vertical direction. That is, since the trajectory M1 of the medicinal solution is directed backward, the medicinal solution hits the back side of the leaf after the nozzle 11 passes through the crop. The effect is the same as in the case of FIG.

  As described with reference to FIG. 1, boom storage support frames 13 and 13 for storing and supporting the spreading boom 9 are erected on both the left and right sides of the machine body, and are configured to be latched and held by the receiver 14. . However, as described with reference to FIGS. 11 to 13, in the configuration in which the inclination angle of the nozzle 11 is inclined forward or backward with respect to the vertical direction, the spreading boom 9 (center boom 9a, left and right spreading boom (side boom)). 9b, 9b) itself is also inclined, so that when the spreading boom 9 is stored in the receiving tool 14, the spreading boom 9 does not come into surface contact with the receiving tool 14. For this reason, there is a possibility of damage if the spreading boom 9 and the receiver 14 are scratched or if there is a strong impact.

  Therefore, as shown in FIG. 14, the receiver 14 is configured to be rotatable. The shaft portion 77 that supports the receiving member 14 has a double structure. Specifically, the receiver 14 is fixed to a boss 73, and the boss 73 is fitted to the shaft 75. A pin 74 is fixed to the boss 73, and a flange 76 having a notch 76 a is fixed to the shaft 75. The pin 74 is configured to enter the notch 76 a of the flange 76.

  Therefore, since the boss 73 rotates within the range of the notch 76a, the receiver 14 also rotates. When the spreading boom 9 is placed in the receiving tool 14, the receiving tool 14 naturally rotates so that the spreading boom 9 and the receiving tool 14 come into surface contact with each other due to the weight of the spreading boom 9. Thereby, damage to the spreading boom 9 and the receiving tool 14 can be prevented.

  Since the receiving device 14 is provided at two places on the left and right sides of the machine body, by sharing the rotating structure of the receiving device 14, the number of parts is reduced and the cost is reduced.
