The tooth portion of the auxiliary wheel 193 is driven into the ground to support the fertilizer / pesticidal sprayer 100 so that it does not fall down.

  In addition, the frame 140 receives electric energy charged in a handle 142 that allows the fertilizer / pesticidal spreader 100 to move while pulling, the moving wheel driving motor 192, and a rotating member driving motor 151 described later. A battery 144 for providing, and an operation panel unit 143 for controlling the moving wheel driving motor 192 and the rotating member driving motor 151 are provided.

  The spray pipe 130 guides the fertilizer sprayed through the discharge port 121 of the blower and disperses the fertilizer to the outside, and is formed of a main body part 131 and a wrinkle pipe part 132. The main body 131 has a shape in which a plurality of pipe pipes are assembled in the longitudinal direction and extend long, and the plurality of pipe pipes can be separated and reassembled for convenience during storage and long-distance movement. It has a simple structure. The wrinkle tube portion 132 is installed between the main body portion 131 and a rotating member 150 described later so that fertilizer can be sprayed forward at a desired angle in the vertical direction. One end of the wrinkle tube 132 is coupled to extend from one end of the main body 131, and the other end is fixed to the rotating member 150.

  The rotating means reciprocally rotates the spray pipe 130 with respect to the frame 140 such that the spraying direction of the fertilizer sprayed through the spray pipe 130 is continuously changed. A drive motor 151 and a power transmission unit are provided.

  The rotating member 150 is connected to the injection pipe 130 and is rotatably supported by the frame 140.

It is sandwiched by 155 and fixed on the outer peripheral surface of the rotating member 150 by a method such as welding. Since the drive gear 152 and the driven gear portion 153 are meshed with each other, the rotational force of the drive gear 152 is directly transmitted to the driven gear portion 153 side, and the rotating member 150 rotates.

  Meanwhile, a transfer pipe 170 is provided for transferring the fertilizer injected from the blower 120 to the injection pipe 130 side. One end 171 of the transfer pipe is connected to one end of the blower 120, and the other end 172 of the transfer pipe is provided with a frame coupling part 172a so as to be fixed and coupled to the frame 140.

The rotation support member 145 is formed of an upper plate 145a and a lower plate 145b facing each other, and a through hole 146 is formed through both the upper plate 145a and the lower plate 146b. The upper plate 145a is provided with both the rotation member driving motor 151 and the speed reducer 154, and the frame coupling portion 172a of the transfer pipe is connected to the lower plate 145b of the rotation support member from the lower side of the lower plate 145b. Combined. An arcuate hole 141 whose center of curvature is located on the rotation center 158 of the rotating member is formed around the through hole 146 of the lower plate 145b of the rotating support member.

  A first sensor 176 and a second sensor 177 are provided for detecting whether the rotating member 150 has rotated to a desired angle range in one direction or the other direction. The first sensor 176 is installed fixed to the lower plate 145b of the rotation support member, while the second sensor 177 is installed so that its position can be changed along the arcuate hole 141. By changing the installation position of the second sensor 177, it is possible to adjust the range of the rotation angle at which the injection pipe 130 reciprocates. As shown in FIG. 7, the first sensor 176 and the second sensor 177 are sandwiched through a hole formed in an end portion of the bolt 161, and the first support 145 is disposed below the rotation support member 145.

Is provided. In the present embodiment, magnetic force detection sensors are used as the first sensor 176 and the second sensor 177. If the rotation member 150 is rotated by inserting a magnet (not shown) into the insertion hole 157 at a desired position among the four insertion holes 157 formed at 90 ° intervals on the edge of the mediating member 156. The magnetic force is detected by the first sensor 176 or the second sensor 177 at a position where the magnet and the first sensor 176 or the second sensor 177 intersect.

  In order to prevent the injection pipe 130 from dropping due to its own weight, a first support member 181 and a second support member 182 for supporting the injection pipe 130 are provided. The first support member 181 is coupled to the rotating member 150 and rotates together with the rotating member 150. The second support member 182 is connected to the first support member 181 and is coupled to the main body 131 of the injection pipe to support the injection pipe 130.

As the second support member 182 rotates, the angle of the injection tube 130 in the vertical direction is adjusted.

  Hereinafter, the operating principle in which the fertilizer or pesticide is sprayed while the fertilizer or pesticide spraying direction is automatically changed in the left-right direction through the fertilizer / pesticide sprayer of the present embodiment configured as described above will be described with reference to FIGS. 7 will be schematically described with reference to FIG.

  First, the fertilizer or pesticide stored in the hopper 110, such as the fertilizer 1, falls to the blower 120 side by its own weight when the valve 113 is opened. The centrifugal force generated by the rotation of the blower fan 125 of the blower is added to the falling fertilizer, and the fertilizer is sent to the discharge port 121 side of the blower in a state in which kinetic energy is ensured to be sprayed to the outside. . The fertilizer sprayed through the outlet 121 of the blower is transferred to the spray pipe 130 along the transfer pipe 170.

  The rotating member driving motor 151 is driven through the operation panel unit 143 to rotate the rotating member 150 in one direction ("A" direction in FIG. 5). If the first sensor 176 senses the magnetic force of the magnet at a position where a magnet (not shown) installed on the rotating member 150 and the first sensor 176 intersect, the driving of the rotating member is performed according to the signal. The motor 151 rotates in the reverse direction, and the rotating member 150 also rotates in the other direction (the “B” direction in FIG. 5) which is the reverse direction of the one direction (the “A” direction). When the rotating member 150 is rotating in the other direction (“B” direction) and the magnet installed on the rotating member 150 and the second sensor 177 intersect, the second sensor 177 is the magnet. , The rotating member driving motor 151 rotates in the opposite direction, and the rotating member 150 rotates again in the one direction ("A" direction). Thus, when the rotating member 150 reciprocates in the left-right direction, the injection pipe 130 coupled to the rotating member 150 can also reciprocate in the left-right direction, and the fertilizer injected through the injection pipe 150 is also automatic. Thus, the spraying direction is changed in the horizontal direction and sprayed.

  In addition, with reference to FIG. 7, an operation principle of changing the position of the second sensor 177 will be schematically described.

  When the position of the second sensor 177 is to be changed, first, the nut 162 is rotated so that the nut 162 moves to the opposite side of the rotation support member 145 and the nut 162 is released. Utilizing this, the second sensor 177 is moved to a desired position. After the second sensor 177 is positioned at a desired position, the position of the second sensor 177 is fixed again by tightening the nut 162 toward the rotation support member 145 again.

  If the fertilizer / pesticidal spreader according to the present embodiment configured as described above is used, it is not necessary for the worker to carry the fertilizer / pesticidal spraying work directly on the fertilizer / pesticidal spreader, and the fertilizer / pesticidal spraying is not required. Since the fertilizer or pesticide is sprayed while automatically changing the spraying direction to the left and right during the work, one worker can easily spray the fertilizer or the pesticide uniformly on a large area of rice fields or fields. Therefore, it is possible to reduce the labor required for the application work of fertilizer or agrochemical, and to obtain the effect of improving the workability per unit area of agricultural land and per unit manpower.

  In addition, if the fertilizer / pesticidal sprayer according to the present embodiment is used, any elderly person or minor who has weak physical strength can easily spray fertilizer or pesticide. Therefore, it is not necessary to pay a high labor cost to young men and hire them to apply fertilizers or pesticides, so that it is possible to prevent excessive labor costs and reduce the production cost of crops.

Unlike the blower 120 of FIG. 2 connected to the hopper 110, the blower 220 of the present embodiment is not connected to the hopper 210. That is, the liquid fertilizer or pesticide does not pass through the blower 220, and only the air is pressurized by the blower 220 and transferred to the injection tube 230 side.

  The transfer unit 240 is for transferring liquid fertilizer or agricultural chemical inside the hopper 210 to the outside of the hopper 210, one end connected to the discharge port of the hopper 210 and the other end connected to the injection pipe 230. Thus, the hopper 210 and the injection pipe 230 are communicated with each other. In the present embodiment, a transfer hose is used as the transfer unit 240. A pressure pump (not shown) is provided in the middle of the transfer path formed by the transfer unit 240, and the liquid fertilizer or pesticide discharged from the hopper 210 is pressurized and injected by the pressure pump. The tube 230 is reachable.

  The injection pipe 230 is connected to the blower 220 and the transfer unit 240.

The magnetic force is sensed by.

  By combining the sensors 271 installed at different positions on the sensor support plate 270, it is possible to rotate the ejection tube 130 within a range of various angles. That is, if two sensors 271 separated by an angle of 180 ° are selected (applying an electrical signal so that magnetic force can be sensed), the injection tube 130 can be rotated within a range of 180 °. If two sensors 271 separated by an angle of 60 ° are selected, the injection tube 130 can be rotated within a range of 60 °. According to the same principle as described above, the injection tube 130 can be rotated within a range of 90 ° or 120 °.
