The positions of the nozzles 56ab and 56bb are changed, and the tank application agent dispersing device 51 can be easily installed even in the seedling table 31 having different distances between rows. Further, the position of the nozzles 56 ab is changed to the inside of the body. In the case of a square, since it acts in the opposite direction in the same manner as described above, the description is omitted. Next, another embodiment of the position changing means will be described. In this case, as shown in Fig. 13, the position changing means 60' provided as the hose 56aa is provided on the outer peripheral surface of the upper end portion of the inner rotating portion 6 1 ', and the projection 61a' is provided at a position opposite thereto. On the other hand, on the upper surface of the outer fixing portion 62', the upper surface of the circumference -24-201134382 is formed with a slide rail 1 for allowing the projection 61a' to slide, and from the relative position of the slide rail 1 along the outer peripheral surface to the outer circumference A plurality of positioning grooves 62a' having the same width as the slide rail 1 are formed at a position in the middle of the surface. Therefore, the conveying portion 56a is such that the inner rotating portion 6 1 ' is fitted to the outer fixing portion 62 ′, and the respective projections 61 a ′ are fitted in the opposing positioning grooves 62 a ′ of the outer fixing portion 62 to fix the inner rotating portion. 61 ', and the position of the nozzle 56ab can be fixed. Further, the projection 61a' is formed by providing a bulging portion at the front end for preventing the projection 6 1 a' from falling off from the slide rail 1 and the positioning groove 62a'. Here, as described above, when the nozzles 5 6ab ( 5 6bb ) are changed toward the outside of the machine, the operator first raises the inner rotating portion 61 ′ so that the respective protrusions 61 a ′ protruding from the positioning grooves 62 a ′ are slipping.

Further, on the outer peripheral surface of the lower end portion of the upper fixing portion 62', the convex portion 64 is formed in the same manner as the positioning concave portion 63, and is formed in the same manner as the positioning concave portion 63. Further, the lower end including the convex portions 64 is made of an elastic member such as synthetic rubber. Therefore, when the position of the nozzle 56ab (56bb) is changed as described above, the operator first lowers the moving portion 61" to release the positioning concave portion 63 and the convex portion 64, and the convex portion 64 is fitted to rotate the lower rotating portion 61" to The positioning recess 63 at the position where the position is changed by the spurt, whereby the convex portion 64 is fixed to the positioning recess 63 which is deformed by the pressing of the convex portion 64, and the rotating portion 6 1" can be fixed. By forming such a configuration, Then, the convex portion 64 is tightly fitted to the fixed portion 63. Since the convex portion 64 can be clamped and fixed in the deformed fixed portion 63, the operator can change the positions of the nozzles 56ab and 56bb without using another tool. However, the tank application agent dispersing device f can easily be used even if the loading distance between the rows is different. For example, the outer circumference of the cymbal section 60 is different from the width of the nozzle, and can be described below as the circumferential surface. In the case of the fitting, the I 56ab can be tightly fitted to the recessed portion of the recessed portion, and the recessed portion is easily 151, and the mounting portion is used for -26-201134382. Further, the convex portion 64 and the positioning concave portion 63 are not limited to the above-mentioned forming position, and may be The convex portion 64 is formed in the lower rotating portion 6 1" The positioning recessed portion 63 is formed as an upper fixing portion 62". Further, the convex portion 64 may be formed in an expanded shape. Next, a configuration of the implanting stop clutch for the planting portion 30 will be described. Refers to a clutch mechanism that is respectively disposed in the planting electric box 37 located in the planting portion 30, and is configured to switch the presence or absence of the driving of the planting unit for each of the planting electric boxes 37. By switching the lever for stopping the planting insertion which is not shown in the driver's seat 21, the row of planting stop levers is provided in accordance with each of the planting electric boxes 37, and the total of four sets can be independently operated. Next, the configuration of the clutch for stopping the planting insertion will be specifically described. Fig. 15 is a plan sectional view showing the inside of the planting box. As shown in Fig. 15, in each of the planting electric boxes 37, A drive transmission shaft 150 that transmits a rotational driving force from a P TO shaft (not shown) provided in the vehicle body 10 is disposed. A first bevel gear is fixed to the rear end of the drive transmission shaft 150. .again In the planting electric box 37, the planting portion drive shaft 152 is disposed along the left-right direction of the vehicle body. The both ends of the planting portion drive shaft 152 protrude outward from the left and right sides of the planting electric box 37, and A rotating box 136a is attached to each of the both end portions. Further, in each of the planting electric boxes 37, a first clutch member 153 that is fitted to the planting portion drive shaft 152 by a spline is disposed; Supporting relative to the planting drive shaft 1 5 2 in a relatively rotatable manner

The first clutch member 153 and the second clutch member 154 are respectively formed with clutch claws that face each other in the axial direction of the planting portion drive shaft 152. Then, the clutch members of the first clutch member 丨5 3 and the second clutch member 154 can be engaged with each other. In other words, the first clutch member 153 and the second clutch member 154 can constitute a snap clutch (a clutch for stopping planting). Further, the first clutch member 153 is attached so as to be relatively rotatable with respect to the planting portion drive shaft 152 by the above-described pin groove fitting. On the other hand, the second helical gear 155 is formed in the second clutch member 154, and the second helical gear 155 is engaged with the first helical gear 151. With the above configuration, in a state in which the first clutch member 153 and the second clutch member 154 are engaged (a state in which the clutch is "contacted"), the driving force of the drive transmission shaft 150 can be transmitted to the planting portion drive shaft 152. Thereby, the planting unit 30 can be driven to the left and right (2 rows) of the electric box 37. On the other hand, since the first clutch member 153 is fitted to the planting portion drive shaft 1 52 by the pin groove, it can be directed away from the second clutch member 1 54 (that is, the direction in which the clutch pawl is released). mobile. Thereby, the clutch is "cut away", and the driving of the planting portion 30 (the two rows) of the electric box 3 7 can be stopped. Further, the first clutch member 153 is biased in a direction in which it engages with the second clutch member 154 by the bias spring 156. Therefore, in the normal state, the first clutch member 丨5 3 and the second clutch member 154 are held in a state of being engaged (the clutch is "contacted"). -28-201134382 Next, a configuration in which the clutch configured as described above can be operated by the row-stopping lever lever 16 will be described. Figure 16 is a side view of the model of the planting box. As shown in Fig. 16, the L-shaped clutch lever 158 is attached to the outer side of each of the planting electric boxes 37 in a state in which the intermediate portion can be rotatably supported by the stopper pin 159. At one end of the clutch lever, a metal wire 160 is connected, and the wire 160 is connected to the aforementioned rowing and stopping lever. By using the lever for stopping the planting operation, the pin 1 59 can be stopped. The position of the clutch causes the clutch lever 1 58 to rotate. Further, at the other end of the clutch lever 158, one end of the clutch operating pin 157 is attached. The other end of the clutch operating pin 157 is inserted into the planting electric box 37. By inserting the planting stop lever in this configuration, the clutch operating pin 157 can be pressed into the planting electric box 37. On the other hand, as shown in Fig. 15, a cam portion 153a is formed in the first clutch member 153. Then, when the clutch operating pin 157 is pressed into the planting electric box 37, the front end of the clutch operating pin 157 abuts against the cam portion 153a, and the first clutch member 153 can be moved away from the second The direction of the clutch member 154 (the direction in which the clutch is "cut away") moves. As described above, by operating the rowing and stopping lever, it is possible to cut off the planting stop clutch for the planting electric box 37, and to insert the two implants in the planting electric box 37. The driving of unit 136 is stopped, and the planting operation can be stopped locally. Next, the configuration of the deriving unit 55 will be described in detail. Figure 1 7 -29- 201134382 is a side cross-sectional view of the spreading unit. As shown in FIG. 7 , the lead-out unit 5 5 includes an export box 55aa (55ba), a take-up roll 125, and a brush 126. The outlet boxes 55aa (55ba)' are attached to the lower portions of the two communication portions 145a formed in the distribution funnel 54, respectively. The lead light 125 is disposed inside the space formed by the lead-out box 55aa (55ba) and the communication portion 145a. The take-up roll 125 is formed into a disk shape having a thickness, and a plurality of recesses 125a are formed by arranging a predetermined interval on the outer peripheral surface thereof. By the above, a granular case applicator in the spreader funnel 54 can be formed. Then, it is dropped into the inside of each of the aforementioned concave portions 125a by a fixed amount. Then, the derivation roller 125 is rotationally driven at a predetermined speed, thereby deriving the light 1 2 5 to function as a so-called waterwheel, and the tank application agent in the distribution funnel 5 4 is directed toward the shooter at a predetermined supply speed (shooter) ) 147 Export. Further, the brush 126' is disposed in contact with the outer peripheral surface of the take-up roll 125. The brush 126 is used to hold the tank application agent so that the phase application agent in the diffuser funnel 54 does not flow downward through the gap of the outlet light 105 151 outlet box 5 5aa (5 5ba). The two lead rollers 125 included in the scattering unit u are fixed to the lead-out drive shaft 148 provided in each of the cloths. Further, the unit side clutch member 1 4 9 described later in Fig. 8 is attached to one end of the drive shaft 1 48. Further, the unit side clutch member 丨49 is disposed on the left side in the traveling direction by the dispersing unit uL, and on the right side is the dispersing unit uR. A clutch pawl is formed on the one-side clutch member 149'. After the -30-201134382, the unit-side clutch member 194 is engaged with the frame-side clutch 176, which will be described later, and the rotational driving force is input to the lead-out drive shaft 148, so that the two units (2 rows) of the scatter unit u are provided. The take-up roll 125 is rotationally driven and the tank applicator in the spreader funnel 54 is derived. Next, a configuration for transmitting the driving force from the planting electric box 37 to the outlet drive 148 provided in each of the spreading units u will be described. First, a configuration for taking out the driving force from the planting electric box 37 will be described. Any one of the aforementioned planting electric boxes 37 is provided with an opening at its rear end portion, and a configuration of driving 161 is attached to the rear end portion. In the case of this embodiment, after the second planting electric box 37 from the left of Fig. 5 is attached, the drive is taken to be 161. The inside of the drive take-out case 161 is shown in Fig. 15. As shown in Fig. 15, a PTO shaft 162 for the spreader is placed inside the drive take-out case 161. At the end of the PTO shaft 162 of the spreader, a third inclined 163 that is engaged with the second helical gear 15 5 is fastened, and a drive gear 164 is fixed to the other end. On the other hand, the movable take-out box 161 is rotatably supported by the drive take-out shaft 1 at the front end of the drive take-out shaft 165, and the trailing gear of the omitted pattern engaged with the drive gear is fixed, and the rear end is provided. Then, it is protruded from the drive 161 toward the rear. With the above configuration, the rotational driving force can be taken out from the planting power 37. Next, a description will be given of a drive transmission mechanism that transmits the rotational drive taken out from the planting electric box 37 to each of the scattering units u. In the 5 3 ' system, a link mechanism that transmits the driving force from the planting portion 30 is provided to simultaneously move the shaft. In addition, the box is calculated to be a box gear, and one gear is driven in the drive 65, 1 64 out of the box, the frame structure (-31 - 201134382 link portion) 191; and the one-way clutch mechanism 170; and the driving force distribution Agency 192. Fig. 18 is a model diagram of the drive transmission mechanism; Fig. 19 is a perspective view showing the drive transmission mechanism. As shown in FIGS. 18 to 19, the link mechanism 191' is provided with a crank plate 166 attached to the rear end of the drive take-out shaft 165, and a longitudinal link member connecting one end to the crank plate 166. 167; and a first drive transmission lever 168 coupled to the other end of the longitudinal link member 167. The rotational motion taken out from the planting electric box 37 by driving the take-out shaft 165 is converted into a vertical reciprocating motion by the crank plate 166 and the longitudinal link member 167, and transmitted to the first drive transmission lever 168. The first drive transmission lever 168 is rotatably attached to a first drive transmission shaft 172 which will be described later. With this configuration, the longitudinal link member 167 is reciprocated upward and downward, and can be converted into a reciprocating rotational motion centering on the axis of the first drive transmission shaft 172 by the first drive transmission lever 186. The one-way clutch mechanism 170 includes a second drive transmission lever 169 that is rotatably attached to the first drive transmission shaft 172, and is configured to transmit only when the second drive transmission lever 169 is rotated in one direction. The driving force is transmitted to the first drive transmission shaft 72. Then, the second drive transmission lever 1 69 ' is configured to be in contact with the first drive transmission lever i 68. Thereby, the reciprocating rotational movement of the first drive transmission lever 168 can be transmitted to the second drive transmission lever 169, and only the one-way clutch mechanism-32-201134382 170 transmits the rotational driving force in one direction to the first drive. The shaft 172 is transmitted. According to the above configuration, the driving force extracted from the planting portion 30 can be transmitted to the first drive transmission shaft 172, and the first drive transmission shaft 172 can be intermittently rotationally driven in one direction. Next, the driving force distribution mechanism 1 92 will be described. The driving force distribution mechanism 192 is composed of the first drive transmission shaft 172, the first drive transmission gear 173, the second drive transmission gear 174, the second drive transmission shaft 175, and the frame side clutch member 176. As shown in Fig. 18, the first drive transmission shaft 1 72 is disposed in the direction in which the dispersing unit u is arranged (the left and right direction of the vehicle body). Further, at the both ends of the first drive transmission shaft 1 72, the first drive transmission gears 1 73 are fixed. Therefore, the tank application agent spreader 40 of the present embodiment includes two first drive transmission gears 173. Further, each of the two first drive transmission gears 173 is provided with a second drive transmission gear 174 that meshes with the first drive transmission gear. Therefore, the tank application agent dispersing device 151 of the present embodiment is provided with two second drive transmission gears 1 74. Further, the first drive transmission gear 1 73 and the second drive transmission gear 174 are housed in the gear case 177. Further, in Fig. 19, in order to more clearly illustrate the configurations of the first drive transmission gear 1 73 and the second drive transmission gear 1 74, the upper portion of the gear case 177 is shown in a broken line in a broken line. The two second drive transmission gears 174 are respectively fixed to the central portion of the second drive transmission shaft 175 disposed in the axial direction. Therefore, the box application agent dispersing device 51 of the present embodiment has two second drives.

S -33- 201134382 Dynamic transmission shaft. The second drive transmission shaft 175 is disposed in parallel with the first drive transmission shaft 172. Then, frame side clutch members 176 are attached to both ends of each of the second drive transmission shafts 75. That is, the tank application agent dispersing device 51 of the present embodiment is provided with four frame side clutch members 176. Further, the four frame side clutch members 丨76 are disposed at positions corresponding to the respective attachment positions of the four scatter units u. The frame side clutch members 176 are formed with the clutch pawls. Then, in a state in which the dispersing unit u is attached to the support frame, the clutch pawl formed on the frame side clutch member 176 and the clutch pawl formed on the unit side clutch member 149 are disposed to face each other in the left-right direction of the vehicle body. . Then, the clutch pawls formed on the two clutch members 149, 176 are configured to be engageable. That is, the unit clutch (biting clutch) 178 can be constituted by the frame side clutch member 176 and the unit side clutch member 149. The unit clutch 178 can be said to be disposed for each of the dispersing units u. With the above configuration, the driving force extracted from one of the planting electric boxes 37 is transmitted via one link mechanism 191 and one one-way clutch mechanism 丨70, and four driving force distribution mechanisms 192 can be used. The unit clutch 178 is assigned. As described above, since the link mechanism 191 and the one-way clutch mechanism 1 7 分别 are each sufficient, the drive transmission mechanism can be formed in a simple configuration. Then, by bringing the unit clutch 178 into a "contact" state (a state in which the unit side clutch member 194 is engaged with the frame side clutch member 176), the driving force can be transmitted to each of the scatter units u. When the drive shaft-34-201134382 148 is taken out, the take-up roller 125« of each of the scattering units u is rotationally driven. Further, when the clutch is configured as a snap-on clutch and the member is disposed at the end of the drive transmission shaft, only Two clutch members can be arranged on one moving shaft. That is, the driving force can only be allocated to two loose elements. In this case, in the above configuration, the transmission gears 173 and 174 are driven by the first drive shaft 172, and the driving force is divided by the plurality of first transmission shafts 175. Therefore, the driving force can be distributed to the three or more scattering sheets by the two frame side clutch members 176 of the plurality of second drive transmission shafts 175. Further, between the drive transmission gears 173 and 174, there are other drive transmission gears (that is, the drive transmission gears 173 may be indirectly engaged with each other). Thereby, the transmission shaft 175 can be driven relatively freely, and the degree of freedom in arranging the distribution unit u can be increased. Further, as described above, in the present embodiment, each of the distributing units u can be disposed at a lower position (the planting electric box 37) by the lead-out unit 5 5 . Thus, a shorter longitudinal link member can be constructed, and the link mechanism 191 can be simply constructed. Next, the structure of the unit clutch 1 78 will be described in detail. FIG. 20 is a perspective view showing the configuration of the vicinity of the clutch unit. The unit side clutch member 149 is oriented toward the frame side clutch by the spring 179. The direction in which the members 176 are engaged. That is, the constitution of the spring 179 can be maintained in the "contact" state by the spring pressure of the spring 179. Separate drive single drive 2 drive end A can also be 1 74 configuration office settings close to 167. First. For example, the configuration of the clutch interlocking mechanism for switching the single-turn clutch 178 to the "cut-away" state in conjunction with the clutch for stopping the planting stop will be described. Fig. 21 is a perspective view showing the support frame in a state after the dispersing unit is removed. As shown in Fig. 21, a frame side clutch operating lever (frame side contact member) 185 is rotatably supported in the frame 53. The frame side clutch operating lever 185 is provided corresponding to the four scatter units u. Therefore, in the frame 53 of the present embodiment, four frame side clutch operating levers 1 8 5 are provided. Further, one end of the clutch operating force transmission wire (clutch operating force transmitting member) 186 is connected to each of the frame side clutch operating levers 185'. Then, as shown in Fig. 16, the other end of each of the clutch operating force transmitting wires 186 is coupled to the clutch operating pin 157 provided in the corresponding planting electric box 37. In the configuration, the frame side clutch operating lever 1 8 5 is rotated by the displacement of the clutch operating pin 157. Here, the term "corresponding planting electric box 37" means the position of the planting electric box 37 corresponding to the position of the distributing unit u. For example, the frame side clutch operating lever 185 corresponding to the leftmost spreading unit u is a clutch operating pin 157 provided by the leftmost implant electric box 37, and a clutch operating force transmitting wire 1 8 6 And the link. Further, for example, the frame side clutch operating lever 185 provided corresponding to the second spreading unit u from the left side is the clutch operating pin 157 provided by the second planting electric box 37 from the left side, and The clutch operating force transmits the wire 186 to be coupled. • 36- 201134382 Thus, when any one of the four rows of planting stop levers is operated, the corresponding clutch operating pin 177 of the planting electric box 37 is pressed into the planting electric box 3 At 7 o'clock, the clutch operating pin 157 is transferred to the frame side clutch operating lever 185 corresponding thereto by the clutch operating force transmitting wire 186, and the frame side clutch operating lever 185 is rotated. In other words, the operation of the clutch for stopping the planting and the operation of the frame side clutch operating lever 185 can be interlocked. Further, Fig. 22 is a perspective view of the dispersing unit; Fig. 23 is a perspective view of the dispersing unit seen from a different angle from Fig. 22. As shown in Figs. 22 to 23, the unit-side clutch operating lever (unit-side contact member) 180 is rotatably attached to the plate-like member 128 of the dispersing unit u. The unit side clutch operating lever 180 is composed of a clutch member abutting portion 181 and an operation input portion 182. The clutch member abutting portion 181 is disposed so as to be able to abut against the collar portion 149a formed on the outer circumference of the unit side clutch member 149. Operation The input unit 1 82 is configured as a plate-like portion and is fixed to the clutch member abutting portion 181. By pressing the operation input portion 182 in the predetermined direction, the unit side clutch operating lever 180 can be rotated in a predetermined direction. Then, the unit-side clutch operating lever 180 is rotated in a predetermined direction, and the clutch member abutting portion 81 presses the unit-side clutch member 149 to displace the unit-side clutch member away from the frame-side clutch member. 1 7 6 direction. By this, the unit clutch 7 8 can be "cut away". -37- 201134382 As shown in Fig. 20, in the state in which the dispersing unit u is mounted, the operation input unit 1 82 of the unit side clutch operating lever 180 and the frame side clutch operating lever 1 8 5 are in close proximity. s position. Then, when the row insertion stop lever is operated, the corresponding frame side clutch operating lever 185 is rotated, and the frame side clutch operating lever 185 is operated with the adjacent unit side clutch operating lever 180. The portion 1 82 contacts 'and pushes the operation input portion 182 in a predetermined direction. With this configuration, the clutch-side abutting portion 1 8 1 pushes the unit-side clutch member 1 49 by the rotation of the unit-side clutch operating lever 180, and the position of the unit-side clutch member 1 49 is displaced to the disengagement frame. The direction of the side clutch member 176, thereby shutting off the unit clutch 178. That is, it is configured such that the row insertion stop clutch and the corresponding unit clutch 178 can be interlocked. Further, as described above, the planting stop clutch for inserting the electric box 37 is configured to stop planting every two rows. On the other hand, the scattering unit u is configured to drive two (two rows) of the take-up rolls 125 by one drive shaft. Therefore, the driving of the two (two-row) lead-out portions 55 can be stopped by one unit clutch 178. Because of this configuration, it is possible to switch the planting and the application of the tank application agent for every two lines by interlocking the rowing stop clutch with the unit clutch. Further, according to the configuration described above, the number of components in the unit clutch relationship can be reduced as compared with the configuration in which one unit clutch is provided to one lead-out unit 55, and the dispersing unit u and the drive transmission mechanism can be easily configured. The configuration for the dispersing unit U can be removed from the frame 53 to add -38-201134382 for explanation. As described above, the unit clutch 178 is configured as a snap-on clutch composed of the unit side clutch member 149 and the frame side clutch member 176. Then, the unit side clutch member 149 is detachable from the frame side clutch member 176. That is, the drive shaft 148 of the spreading unit u can be cut away from the drive transmission mechanism on the side of the frame 53 at a portion of the unit clutch 178. When the unit clutch 178 is configured as a snap-in clutch, when the dispersing unit u is detached from the frame 53, since the detaching operation of the mechanism for transmitting and transmitting is not required, the scatter unit can be easily detached. u. Further, as described above, the unit side clutch operating lever 180 and the frame side clutch operating lever 185 (not mechanically coupled) are merely in close proximity to each other. Thus, the unit side clutch operating lever 180 can be separated from the frame side clutch operating lever 18. Thereby, when the dispersing unit u is detached from the frame 53, since the unloading operation of the mechanism (e.g., metal wire) for transmitting the clutch operating force is not required, the dispersing unit u can be easily removed. Further, in the conventional box applicator spreader, since the lead-out portion cannot be easily cut away from the drive transmission mechanism on the frame side, the spread funnel and the lead-out portion cannot be collectively removed as a unit. Therefore, in the conventional box applicator spreader, in order to be able to easily discharge the medicine remaining in the scattering funnel, a configuration in which only the scattering funnel can be removed can be formed. In this configuration, it is not possible to strongly connect the scattering funnel and the lead-out portion, and there is a problem that rainwater infiltrates from the gap between the distribution funnel and the lead-out portion to elute the medicine. Also, since the export unit cannot be removed from the frame, it cannot be easily

S -39- 201134382 The medicine remaining inside the lead-out part is discharged. In this embodiment, by arranging the scattering unit and the drive transmission mechanism as described above, the drive transmission mechanism can be easily separated from the lead-out portion 55 from the frame 53 side. Therefore, the scattering funnel 54, the lead-out portion 55, the shooter 147, and the like can be collectively integrated to constitute the scattering unit u, and the scattering unit u is detached from the frame 53 for each of the scattering units u. Therefore, in the configuration of the present embodiment, in order to discharge the medicine remaining in the distribution funnel 54 and the lead-out portion 55, the scattering unit u may be removed, and the opening lid portion 54a may be inverted for each of the scattering units u. Therefore, it is not necessary to simply separate the spread funnel from the lead-out portion as in the conventional box applicator spreader. Therefore, in the present embodiment, the distribution funnel 54 and the outlet box 55aa (55ab) are screwed. In this way, since the spreader funnel 5 4 and the outlet box 5 5 aa ( 5 5 ab ) can be strongly connected, the sealing property is improved more than conventionally, and rainwater or the like is less likely to intrude into the interior. Next, a configuration for fixing each of the scattering units u to the frame 53 will be described. As shown in Fig. 2, in the frame 523, mounting struts 187 for carrying the displacing unit u are disposed at the mounting positions of the respective scatter units u. Each of the mounting stays 187 is composed of two leg portions 1 8 8 ' which are arranged side by side in the left-right direction of the vehicle body and a plate-shaped horizontal portion 189 horizontally spanned between the leg portions 1 88. On the other hand, as shown in Fig. 22 and Fig. 23, the round bar member 1 27 and the plate member 1 2 8 provided in the scattering unit u are respectively disposed in the left-right direction of the vehicle body (and the derivation drive shaft 148). Parallel direction). When the spreading unit u is carried on the mounting stay 187, the round bar member 127 is respectively carried over the leg portion 188, and the plate member 128 is carried on the horizontal portion 189. Thereby, since the scattering unit u can be supported by at least three points by the two leg portions 188 and the horizontal portion 189, the posture of the scattering unit u can be stabilized. On the other hand, as shown in Fig. 2, the leg portion 188 is formed with an inclined portion 188a and a U-shaped portion 188b formed continuously from the lower end of the inclined portion 188a. With this configuration, when the spreading unit u is carried on the mounting stay 1 8 7 , the scattering unit u is slid downward by its own weight in a state where the round bar member 1 27 is brought into contact with the inclined portion 188a. The way to move. Thus, the round bar member 127 is naturally guided by the inclined portion 188a, and the round bar member 1 27 is embedded inside the U-shaped portion 18 8b, whereby the spreading unit u can be before and after the vehicle body Directional positioning. Then, in a state in which the dispersing unit u is positioned in the front-rear direction of the vehicle body, the clutch members 149 and 176 are mutually opposed to each other. Further, the horizontal portion 189 and the plate-like member 128 each have a certain length in the left-right direction of the vehicle body. That is, even if the position of the spreading unit u is shifted to some extent in the left-right direction of the vehicle body, the plate-like member 128 can be carried on the horizontal portion 189. On the other hand, the interval between the two leg portions 1 8 8 is shorter than the length in the left-right direction of the body of the round bar member 127. That is, even if the position of the distributing unit u is shifted to some extent in the left-right direction of the vehicle body, the round bar member 127 can be carried on the two leg portions 188. Therefore, in a state in which the round bar member 127 is carried by the leg portion 188 and the plate-like member 128 is carried by the horizontal portion 189, even if the scattering unit u is moved to the left and right direction of the vehicle body to some extent, the leg portion can be used. 188 and level 5 -41 - 201134382 Part 189 stably supports the spreading unit u at least 3 points. In other words, the dispersing unit u can be slid in the left-right direction of the vehicle body (i.e., the direction in which the clutch members 149 and 176 are indirectly contacted or separated from each other) while maintaining the posture of the dispersing unit u. Thus, for example, in a state where the clutch members 1 4 9 ' 1 7 6 are apart from each other, the spreading unit u can be stably temporarily placed on the mounting stay 187. Since the scattering unit u can be temporarily set in this way, the mounting work of the scattering unit u can be easily performed. Then, in the temporarily set state (the state in which the round bar member 127 is fitted in the U-shaped portion 188b), since the spreading unit u can be positioned in the front-rear direction of the vehicle body, the scattering unit u is placed on the mounting stay 187 toward By sliding the vehicle body in the left-right direction, the clutch members 1 49, 1 76 can be simply engaged with each other. Further, the positioning of the vehicle unit in the left-right direction of the scattering unit u can be embedded in the convex portion 1 89a formed in the horizontal portion 189 by the hole portion 128a (see FIG. 23) formed in the plate-like member 128 (refer to Figure 21). Further, in the vicinity of the attachment stay 187, a fixture 190 is disposed (refer to Fig. 21). The fixture 190 is configured such that a hook member 127a (refer to FIG. 22) fixed to the round bar member 127 can be hooked and fixed, and then the fixture 1 90 can be configured to be a single button (for example, one) The finger is simply switched: a state in which the hook member 1 27a is hooked and fixed, and an open state. Therefore, after the positioning unit u is positioned, the fixing unit u can be simply fixed to the mounting stay 187 by hooking the fixing member 190 to the hook member 127a. -42- 201134382 If the above is fixed by the fixture 1 90, the installation of the scattering unit u can be completed. Then, as long as the dispersing unit u is attached to the frame 5 3, the state in which the clutch members 1 4 9 and 1 7 6 are engaged with each other (the state in which the drive shaft 148 is connected to the drive transmission mechanism) can be formed. In this way, the mounting and unloading operation of the dispersing unit u can be easily performed without the need for screw fixing or the operation of the driving transmission mechanism or the clutch operating mechanism. 1 a is used to explain. Fig. 24 is a rear view showing a state in which the loaded seedling stage is placed. As described above, in the present embodiment, the seedling stage 31a of two rows is configured to be detachable from the main seedling table 31. On the other hand, as shown in Fig. 21 and the like, the frame 53 is provided with a temporary setting stay 196 on which the fixed distributing unit u can be placed. Further, as shown in Fig. 18, two temporary staying bars 196 are provided, and are respectively disposed at the left and right end portions of the vehicle body close to the frame 53. When the seedling loading table 31a is separated from the main seedling table 31, first, the two scattering units u of the four scattering units u which are close to the center in the left-right direction of the vehicle body are moved to the temporary setting stays 196 and fixed. . Thereby, the space can be vacated near the center in the left-right direction of the vehicle body. Then, the seedling stage 31a is separated from the main seedling stage 31 and attached to the support tube 197. Then, as shown in Fig. 24, the seedling loading table 31a attached to the support pipe 197 is disposed in a space formed by moving the two scattering units u located at the center to the temporary struts 196. The separated seedling table 3 1 a is mounted on the support tube 1 97,

S -43- 201134382 is placed above the remaining main load table 3 1 . Then, the seedling table 3 1 a ' is a position that overlaps the scattering unit u in a side view. Here, assuming that the scattering unit u cannot be moved to empty the space, it is necessary to arrange the loading table 3 1 a and the scattering unit u in a side view so as not to overlap (in order to avoid the seedling table 31a and the scattering unit u) put one's oar in). Therefore, in this case, it is necessary to avoid the dispersing unit u and set the mounting position of the loading table 3A to a higher position. Therefore, it becomes difficult to mount the seedling table 31a to the support pipe 197. . In this embodiment, as described above, by forming the space by moving the scattering unit u, the seedling loading table 31a can be attached to a lower position. Further, since there is a space in the center of the vehicle body, the dispersing unit u does not cause trouble when the mounting work of the loading platform 31a is performed. Then, such a configuration is the first thing by simply arranging the dispersing unit u from the frame 53 to be easily removed. As described above, since the scattering unit u can be removed, the medicine remaining inside the scattering funnel 54 can be easily discharged by, for example, turning over the dispersing unit u after the removal. Then, since the dispersing funnel 54 and the lead-out portion 55 can be collectively processed, it is not necessary to disassemble the dispersing funnel structure from the lead-out portion as in the conventional drug dispersing device, and the diffuser funnel can be improved. The seal between the 54 and the lead-out portion 55. Further, it may be stored in each unit in advance in a state where the scattering unit u is removed. Further, in the box application agent dispersing device 51 of the present embodiment, the driving mechanism for transmitting the driving force extracted from the rice transplanter to the vicinity of each of the scattering units u is disposed in the frame 53', and the scattering unit is ^ Mounting -44 - 201134382 In the frame 53, the drive shaft M8 and the drive transmission mechanism can be connected, whereby the drive shaft 1 48 can be connected to the drive transmission mechanism by attaching the spreading unit u to the frame 53. Therefore, the work of attaching the camping cloth unit u to the frame 53 can be easily performed. Further, in the tank application agent dispersing device 51 of the present embodiment, each of the # cloth units u includes a unit side clutch member 149 fixed to one end of the lead-out drive shaft 148. In the frame 53, a frame side clutch member 176 having a driving force transmitted from an output drive transmission mechanism is disposed for each of the scatter units u. The drive shaft 148 and the drive transmission mechanism can be connected by the unit side clutch member 149 being engaged with the frame side clutch member 176. Then, the unit side clutch member 148 is detachable from the frame side clutch member 176. As described above, by providing the clutch corresponding to each of the spreading units u, the presence or absence of the driving of the lead-out unit 55 can be switched for each of the distributing units u. Then, since the clutch is configured as a snap-on clutch, the scatter unit u can be detached from the frame 53 at the nip portion of the unit-side clutch member 149 and the frame-side clutch member 丨 76, so when the unit is detached, This unloading operation can be easily performed as needed to remove the drive transmission mechanism. Further, the 'bite clutch' can transmit the driving force by simply bringing the clutch members 149 and 176 into close contact with each other, so that it is possible to simply connect the derivation drive shaft 148 and the drive transmission mechanism by attaching the dispersing unit u to the frame 53. Composition. Further, since the spreading unit u is slid by the mounting stay 1 87 as a guide, the scattering unit u can be attached or detached, so that the separation can be easily performed.

S -45 - 201134382 The positional alignment of the clutch members 149, 176 with each other. Then, the fixing unit u is fixed by the fixing tool 190, whereby the unit-side clutch member M9 can be engaged with the frame-side clutch members 1 to 6 (the state in which the drive shaft 1 4 8 is connected to the drive transmission mechanism). Further, since the posture of the spreading unit u in the middle of the mounting or the unloading can be maintained by the mounting stay 187', it is not necessary to support by hand in order to prevent the spreading unit u from falling over during the mounting or unloading operation. Also, for example, the dispensing unit u can be temporarily placed on the mounting stay 187 before the installation work. Thereby, the mounting or unloading operation of the spreading unit u can be performed more easily. Further, in the tank application agent dispersing device 5 1 of the present embodiment, the unit side clutch member 149 can be displaced and the clutch can be changed in accordance with the operating force of the clutch. Further, with the boundary between the unit side clutch operating lever 180 and the frame side clutch operating lever 185 as a boundary, the distributing unit u can be separated from the frame 53. Thereby, the unloading operation can be easily performed without the need to remove the mechanism for operating the clutch when the dispersing unit is removed. Further, in the rice transplanter 1 of the present embodiment, by temporarily removing the dispersing unit u and carrying the temporary stay 196, the space can be vacated in the place where the distributing unit u is present. Then, in the vacant space, the separated seedling loading table 31a can be disposed.

In addition, the seedling table can also be folded and stored as follows. Fig. 25 is a schematic view showing the action of the seedling stage of the folded planting portion; Fig. 26 is an arrow view of Fig. 25A. As shown in Fig. 25, for example, the seedling stations 31A to 31H-46 to 201134382 are grouped into four units. That is, the seedling loading tables 31A and 31B are the first unit, the seedling loading tables 31C and 31D are the second unit, the seedling loading tables 31E and 31F are the third unit, and the seedling loading tables 31G and 31H are the fourth unit. Further, the seedling loading tables 31A to 31H' are coupled to each other by forming a locking lever (locking lever) provided in each of the edge portions. Further, a tubular stand S to be described later is fixed to the left edge portion of the seedling table 31E and the right edge portion of the seedling table 31F. Further, a pin (projection portion) R fitted to the front end of the holder S is provided on the back surface of the left end portion of the seedling table 31A and the back surface of the right end portion of the seedling table 3 i B. The pin R and the front end of the bracket s are further provided with a snap lock, and the spring lock can be used for locking. Further, the scattering units 73 A to 73D constituting each of the scattering units u are placed on a series of frames 53 and fixed by a spring lock or the like. The frame 5 3 ' is supported by a bracket provided from the four planting transmission boxes 37. The frame 53 is provided with a holding portion 53a similar to the above-described stay 196. The holding portion 53a' is for temporarily placing the respective scattering units 73 A to 73D. Next, a method of folding the first unit (the seedling table 31A, 31B) of the seedling loading tables 31A to 31H to narrow the width of the seedling loading table 31 after the end of the transplanting operation will be described. The funnel unit 73 C located before the third unit (the seedling table 31E, 31F) is removed from the frame 53 and placed on the frame 53 (below the funnel unit 73D) holding portion 53a, and then the spring The lock is fixed. Then, in a state where the seedling table 3 1 A is connected to the seedling table 3 1 B, the connection between the seedling loading table 31B and the seedling loading table 31C is released. More specifically, the two connection levers at the edge portion of the seedling table 31B are placed in the state of "47" to release the connection between the seedling table 31B and the seedling table 31C. The first unit that moves at both ends of the first unit (the seedling stages 31A, 31B) moves. Then, the first unit is superposed on the third unit (the seedling stage 31F). In detail, in the pair of brackets s provided in the third unit, the two pins R placed in the first unit are respectively inserted (the 26th figure, and locked by a spring lock (not shown). Then, the device is placed in the unit. The front end of the hook-shaped fixing pin at the left end portion is hooked to the hole formed on the back surface of the first unit. Next, the jaw plate on which the first unit is placed is folded. By doing so, the width of the rice transplanter 1 is In the state in which the vehicle body 10 and the plug are connected, the truck body 10 is loaded and transported to a truck or the like. Further, the state after the folding unit can be self-folded by performing the above-described order in reverse. The detailed description is omitted. Next, the seedling table 31 is provided with a straw board 60 throughout the wide area of the seedling loading table 31. Fig. 27 is a side view showing the grass dividing board; The figure has another planting view of the branching board. The grass board 60 is detailed as shown in Fig. 27(a) and (b) by a rectangular plate and a certain thickness of the metal plate (plate). 60 is not limited to metal plates, but also plastic plates, etc.) Pin 62 is fixed to an upper portion other than the edge carrier ί bracket 61 is fixed in the portion 31Ε. Further, the grass dividing board 60 is preferably placed in the direction of the loading table 31, and the handle is made to be 3 1 Ε, the front end). The third single-unit 1 seedling is taken out and becomes the rowing machine 1 as shown in the side of the first single-degree direction of the planting part, and it is divided into two. The sub-S' table 3 1 of the seedlings -48- 201134382 The length direction D of the S movable partition 60 can be set by the angle α (in other words, it is obliquely disposed at an angle opposite to the moving direction of the seedling S). The plate 60 opens the seedling root of the seedling S, and it is easy to give the agent ρ to the seedling root of the seedling S, preferably 30 to 60 degrees. Further, the width W of the grass board 60 is preferably The height difference of the plurality of seedlings S placed on the seedling table is appropriately set. For example, considering the difference between the seedlings and the usual seedlings, the grass board 60» which is set to W = 50 mm is constructed in such a manner that even in the mixture The state of the seedlings having different fertility conditions can also cause the grass board 60 to reliably abut the upper part of the seedling S, and open the seedling root of the seedling, and supply the medicine to the seedling root of the seedling S. Next, the description is such that The transplanting machine for the seedlings to spread the medicament. The seedlings S placed on the seedling table 31 are The conveyance belt B is transported to the lower side. When the abutment blade 60 is abutted, the upper portion is warped in the conveyance direction and a space is formed in the root portion. Through this space, the medicine P can be supplied to the seedling S from each of the dispersion units u. Then, the warped seedling S will return to its original state when its front end portion is away from the lower end of the straw board. Thus, the seedlings S of the seedling table 3 1 can be transported one by one to Below, and from the abutting grass board 6 seedlings, the seedlings are sequentially warped, and a space is formed in the seedling roots. Then, the medicine P is supplied to the seedling roots. Fig. 28 (a) and (b) show the present invention. In the other example, two branch straws 80A and 80B are provided in parallel at a predetermined interval L instead of one of the grass blades (the grass straws are not limited to two or three or more). In addition, between 2 branches of straw 80A' 80B

S -49- 201134382 L, set to L = 50mm or so. By replacing the grass board 60 with the grass sticks 80A, 80B, it is possible to provide the same implanted portion with light weight. In this example, the brackets 81 fixed to the outer edge portion 3 1 E of the seedling table 31 are fixed to both ends of the weeding bars 8A and 80B by welding or the like. In addition, the operation of spreading the medicine p to the seedling S is omitted from the same as the above-described example.
