[ The clutch claws of the first clutch member 153 and the second clutch member 154 are engageable. That is, the first clutch member 153 and the second clutch member 154 constitute an engaging clutch (coarse clutch).

In addition, the first clutch member 153 is attached so as not to be rotatable relative to the driven shaft 152 by the spline fitting. A second bevel gear 155 is formed on the second clutch member 154 and the second bevel gear 155 is engaged with the first bevel gear 151. With the above-described structure, when the first clutch member 153 and the second clutch member 154 are engaged (clutch "on" state), the driving force of the driving transmission shaft 150 is transmitted to the driven- And the right and left (two pairs of) cooking chambers 30 can be driven.

On the other hand, since the first clutch member 153 is spline-fitted to the driven side drive shaft 152, the first clutch member 153 is moved in the direction away from the second clutch member 154 (i.e., the direction in which the engagement of the clutch claw is released) It is possible. Thereby, the clutch can be turned " off " to stop driving the right and left (two pairs of) cooking chambers 30. On the other hand, the first clutch member 153 is pressed in the direction of engagement with the second clutch member 154 by the pressing spring 156. [ Therefore, normally, the first clutch member 153 and the second clutch member 154 are held in the engaged state (clutch "on" state).

Next, a configuration for making the clutch configured as described above operable by the coarse stop lever 16 will be described. 16 is a schematic side view of the food case. 16, the clutch lever 158 formed in an L-shape is attached to the outside of each eating-and-die transmission case 37 in a state in which the intermediate portion thereof is rotatably supported by the fixing pin 159 have.

One end of the clutch operating pin 157 is attached to the other end of the clutch lever 158. The other end of the clutch operating pin 157 is inserted into the eating-part transmission case 37 internally. With this configuration, by operating the coarse stop lever, the clutch operating pin 157 can be pushed into the eating-part transmission case 37. On the other hand, as shown in Fig. 15, the first clutch member 153 is provided with a cam portion 153a. When the clutch operating pin 157 is pushed into the foodtransmission case 37, the tip of the clutch operating pin 157 comes into contact with the cam portion 153a to move the first clutch member 153 to the second (In the direction of the clutch " OFF " state) away from the clutch member 154. [

As described above, the coarse stop clutch of the corresponding eating-piece transmission case 37 is cut by operating the coarse stop lever to stop the driving of the two eating units 136 provided in the eating-end transmission case 37, So that it can stop partly.

Next, the configuration of the supply unit 55 will be described in detail. 17 is a side sectional view of the spraying unit. 17, the supply unit 55 includes a supply case 55aa (55ba), a supply roll 125, and a brush 126. As shown in Fig. The supply case 55aa (55ba) is attached to the lower portion of the two communication portions 145a formed in the spray water hopper 54, respectively. A supply roll 125 is disposed inside the space formed by the supply case 55aa (55ba) and the communication portion 145a. The supply roll 125 is formed in the shape of a disk having a thickness, and a plurality of concave portions 125a are formed on the outer circumferential surface thereof at predetermined intervals.

As described above, the granular seed box dispensing agent in the spray water hopper 54 can be dropped into the respective recesses 125a by a predetermined amount. The supply roll 125 rotates at a predetermined speed so that the supply roll 125 functions like a so-called water wheel so that the seedling box application agent in the spray water hopper 54 is directed toward the shooter 147 And can be supplied at a predetermined supply speed.

The brush 126 is disposed so as to contact the outer circumferential surface of the supply roll 125. The brush 126 is used to confine the seedling box applicator so that the seedling box applicator in the spray water hopper 54 does not flow downward through the gap between the supply roll 125 and the supply case 55aa (55ba) .

Two supply rolls 125 of the spray unit u are fixed to the supply drive shaft 148 of each spray unit u. A unit-side clutch member 149, which will be described later with reference to Fig. 18, is attached to one end of the supply drive shaft 148. Fig. On the other hand, the unit-side clutch member 149 is provided on the left side toward the traveling direction, and the spray unit uR is provided on the right side.

The unit side clutch member 149 is provided with a clutch claw. As the unit side clutch member 149 is engaged with the frame side clutch member 176 to be described later and the rotational drive force is inputted to the supply drive shaft 148, the two (two) The roll 125 is simultaneously driven to rotate, and the seedling box applicator in the spray water hopper 54 is supplied.

Next, the configuration for transmitting the driving force from the eating-part transmission case 37 to the supply driving shaft 148 provided in each of the spray units u will be described. First, a configuration for taking out driving force from the eating-and-food transmission case 37 will be described. Any one of the four food -tower transmission cases 37 arranged in the four positions is configured such that a rear end thereof is opened and a drive take-out case 161 is attached to the rear end thereof. In the case of the present embodiment, the drive take-out case 161 is attached to the rear end of the second eating-part transmission case 37 from the left in Fig. The inside of the drive take-out case 161 is shown in Fig.

As shown in Fig. 15, a PTO shaft 162 for a spreader is disposed inside the drive take-out case 161. As shown in Fig. A third bevel gear 163 engaged with the second bevel gear 155 is fixed to one end of the PTO shaft 162 for the spreader and a driving gear 164 is fixed to the other end. On the other hand, a drive take-out shaft 165 is rotatably supported on the drive take-out case 161, and a driven gear (not shown) engaged with the drive gear 164 is fixed And the rear end protrudes rearward from the drive take-out case 161. [ With the above-described configuration, it is possible to extract the rotational driving force from the rear of the eating-and-feeding transmission case 37.

Next, the drive transmission mechanism for transmitting the rotational driving force taken out from the eating-part transmission case 37 to each of the spray units u will be described. A link mechanism (link portion) 191, a one-way clutch mechanism 170, and a drive force distributing mechanism 192 are provided in the frame 53 to transmit the drive force from the molding portion 30.

Fig. 18 is a schematic diagram of the drive transmission mechanism, and Fig. 19 is a perspective view for explaining the drive transmission mechanism. 18 to 19, the link mechanism 191 includes a crank plate 166 attached to the rear end of the drive take-off shaft 165 and a vertical link member 167 (one end connected to the crank plate 166) And a first drive transmission lever 168 connected to the other end of the vertical link member 167. The rotary motion taken out from the food-feeding transmission case 37 by the drive output shaft 165 is converted into a vertical reciprocating motion by the crank plate 166 and the vertical link member 167, .

The first drive transmission lever 168 is rotatably attached to the first drive transmission shaft 172 to be described later. With such a configuration, the vertical reciprocating motion of the vertical link member 167 is converted by the first drive transmission lever 168 into a reciprocating rotational motion about the axis of the first drive transmission shaft 172.

The one-way clutch mechanism 170 is provided with a second drive transmission lever 169 rotatably attached to the first drive transmission shaft 172, and the second drive transmission lever 169 rotates in one direction So that the driving force is transmitted to the first drive transmission shaft 172 only when the first drive transmission shaft 172 is rotated. The second drive transmission lever 169 is configured to be able to contact the first drive transmission lever 168.

Thereby, the reciprocating rotational motion of the first drive transmitting lever 168 is transmitted to the second drive transmitting lever 169, and only the rotational driving force in one direction is transmitted to the first drive transmitting shaft 172. With the above configuration, the driving force taken out from the molding portion 30 can be transmitted to the first driving transmission shaft 172, and the first driving transmission shaft 172 can be intermittently rotated in one direction.

Next, the driving force distribution mechanism 192 will be described. The driving force distribution mechanism 192 includes the first driving transmission shaft 172, the first driving transmission gear 173, the second driving transmission gear 174, the second driving transmission shaft 175, Side clutch member 176 as shown in Fig.

As shown in Fig. 18, the first drive transmission shaft 172 is provided in a direction in which the spray units u are arranged (lateral direction of the vehicle body). Further, first drive transmission gears 173 are fixed to both ends of the first drive transmission shaft 172, respectively. Therefore, the seedling box dispenser 40 of the present embodiment has two first drive transmission gears 173. In addition, a second drive transmission gear 174 is provided corresponding to each of the two first drive transmission gears 173 so as to engage with the corresponding first drive transmission gear.

Therefore, the seedlings box dispenser 51 according to the present embodiment has two second drive transmission gears 174. On the other hand, the first drive transmission gear 173 and the second drive transmission gear 174 are housed in a gear case 177. On the other hand, in FIG. 19, in order to better show the configurations of the first drive transmission gear 173 and the second drive transmission gear 174, the upper part of the gear case 177 is shown with a dotted line.

The two second drive transmission gears 174 are fixedly mounted on the central portion in the axial direction of the second drive transmission shaft 175 disposed corresponding thereto. Therefore, the seedlings box dispenser 51 according to the present embodiment has two second drive transmission shafts. The second drive transmission shaft 175 is disposed in parallel with the first drive transmission shaft 172. A frame-side clutch member 176 is attached to both ends of each second drive transmission shaft 175. That is, the seedling casting box dispenser 51 according to the present embodiment includes four frame-side clutch members 176. The four frame-side clutch members 176 are disposed at positions corresponding to the respective attachment positions of the four spray units u.

The frame side clutch member 176 is provided with a clutch claw. In a state where the spray unit u is attached to the support frame, the clutch claw formed on the frame side clutch member 176 and the clutch claw formed on the unit side clutch member 149 are disposed to face each other in the lateral direction of the vehicle body have. The clutch claws formed on the two clutch members 149 and 176 are configured to be engageable. That is, the unit clutch (engaging clutch) 178 is constituted by the frame side clutch member 176 and the unit side clutch member 149. The unit clutch 178 may be arranged for each of the spray units u.

With the above-described configuration, the driving force taken out from one eating-part transmission case 37 is transmitted through one link mechanism 191 and one one-way clutch mechanism 170, and four Can be distributed to the unit clutch (178). As described above, since only one link mechanism 191 and one-way clutch mechanism 170 are provided, the drive transmission mechanism can be configured in a simple manner.

The drive force is transmitted to the supply drive shaft 148 of each of the spray units u by setting the unit clutch 178 to the " ON " state (the unit- So that the supply roll 125 of each spray unit u can be rotationally driven.

On the other hand, when the clutch is configured as an engaging clutch and the clutch member is disposed at the end of the drive transmission shaft, it can not be disposed only to the two clutch members on one drive transmission shaft. That is, it is possible to distribute the driving force only to the two spraying units. Therefore, in the above-described configuration, the driving force is branched from the first drive transmission shaft 172 via the drive transmission gears 173 and 174 to the plurality of second drive transmission shafts 175.

Therefore, by attaching the frame-side clutch member 176 to both ends of the plurality of second drive transmission shafts 175, it is possible to distribute the driving force also to three or more spraying units u. Further, another drive transmission gear may be provided between the drive transmission gears 173 and 174 (that is, the drive transmission gears 173 and 174 may be indirectly engaged). Thereby, the second drive transmission shaft 175 can be arranged relatively freely, and the degree of freedom in layout of the spray unit u can be increased.

As described above, in the present embodiment, the supply unit 55 is provided for each tank, so that the respective spray units u can be arranged at a low position (in the vicinity of the foodtrain transmission case 37). Therefore, the vertical link member 167 can be configured to be short, so that the link mechanism 191 can be simply configured.

Next, the structure of the unit clutch 178 will be described in detail. Fig. 20 is an enlarged perspective view showing a configuration in the vicinity of the unit clutch. Fig. As shown in Fig. 20, the unit side clutch member 149 is urged by the urging spring 179 in a direction to engage with the frame side clutch member 176. [ That is, the unit clutch 178 is kept in the " on " state by the urging force of the pressure spring 179. [

Next, the configuration of the clutch interlocking mechanism for switching the unit clutch 178 to the " off " state in conjunction with the coarse stop clutch will be described. 21 is a perspective view showing a support frame with the spraying unit removed therefrom. 21, a frame-side clutch operation lever (frame-side contact member) 185 is rotatably supported on the frame 53. As shown in Fig. The frame-side clutch operation lever 185 is provided corresponding to the four spray units u.

Therefore, in the frame 53 of this embodiment, four frame-side clutch operation levers 185 are provided. To each of the frame-side clutch operation levers 185, one end of a clutch operation force transmission wire (clutch operation force transmission member) 186 is connected. 16, the other end of each of the clutch-operating-force transmitting wires 186 is connected to a clutch operating pin 157 provided in the corresponding eating-and-breaking transmission case 37. As shown in Fig. With this configuration, the frame-side clutch operation lever 185 can be rotated in accordance with the displacement of the clutch operation pin 157. [

Here, the " corresponding eating-part transmission case 37 " refers to the eating-comprehension transmission case 37 corresponding to the position of the sprinkling unit u. For example, the frame-side clutch operation lever 185 provided corresponding to the leftmost spooling unit u is provided with the clutch operation pin 157 provided in the leftmost eating-and-living transmission case 37 and the clutch operation force transmission wire 186 ). For example, the frame-side clutch operation lever 185 provided corresponding to the second spraying unit u from the left is provided with the clutch operation pin 157 provided in the second foodtus transmission case 37 from the left side, And is connected by an operation force transmission wire 186.

When any one of the four coarse stop levers is operated and the clutch operating pin 157 of the corresponding eating-and-feeding case 37 is pushed into the eating-and-drinking case 37, The clutch operation force transmission wire 186 transfers the displacement of the frame-side clutch operation lever 185 to the frame-side clutch operation lever 185 corresponding thereto, so that the frame-side clutch operation lever 185 can be rotated. That is, the operation of the coarse stop clutch and the operation of the frame-side clutch operation lever 185 can be interlocked with each other.

22 is a perspective view of the spraying unit, and Fig. 23 is a perspective view of the spraying unit seen from an angle different from that of Fig. As shown in Figs. 22 to 23, unit-side clutch operation levers (unit-side contact members) 180 are rotatably attached to the plate-like members 128 of the spray unit u. The unit-side clutch operation lever 180 includes a clutch member abutment portion 181 and an operation input portion 182.

The clutch member abutment portion 181 is disposed so as to be able to abut the flange portion 149a formed on the outer periphery of the unit side clutch member 149. [ The operation input portion 182 is configured as a plate-like portion and is fixed to the clutch member abutment portion 181. By pushing the operation input portion 182 in a predetermined direction, the unit-side clutch operation lever 180 can be rotated in a predetermined direction.

The unit-side clutch operation lever 180 rotates in a predetermined direction so that the clutch-member abutment portion 181 presses the unit-side clutch member 149 to engage the unit-side clutch member 149 with the frame- 176 in the direction of moving away from each other. Thereby, the unit clutch 78 can be brought into the " off " state.

20, the state in which the operation unit 182 of the unit-side clutch operation lever 180 and the frame-side clutch operation lever 185 are close to each other is a state in which the sprinkling unit u is attached have. When the coarse stop lever is operated, the frame-side clutch operation lever 185 corresponding to the frame-side clutch operation lever 185 rotates and the operation-input portion 182 of the unit-side clutch operation lever 180 And pushes the operation input section 182 in a predetermined direction.

Thereby, the unit-side clutch operation lever 180 rotates and the clutch-member abutment portion 181 presses the unit-side clutch member 149, and the position of the unit-side clutch member 149 is set to the frame- So that the unit clutch 178 is disconnected. That is, the coarse stop clutch and the corresponding unit clutch 178 can be interlocked with each other.

On the other hand, as described above, the coarse stop clutch of the eating-part transmission case 37 is configured to stop the food portion every two sets. On the other hand, the spray unit u is configured to drive two (two pairs) of supply rolls 125 with one drive shaft. Therefore, it is possible to stop the driving of two (two sets) of the supply portions 55 by one unit clutch 178. [

With this arrangement, the coarse stop clutch and the unit clutch are interlocked so that the presence of the food portion and the seedling box dispensing agent application can be switched every two sets. Further, by constituting as described above, it is possible to reduce the number of parts related to the unit clutch, compared to a configuration in which one unit clutch is provided for one supply portion 55, It can be configured simply.

Next, a description will be given of a configuration for making the spray unit u detachable from the frame 53. Fig. As described above, the unit clutch 178 is configured as an engaging clutch composed of the unit side clutch member 149 and the frame side clutch member 176. [ Then, the unit side clutch member 149 can be separated from the frame side clutch member 176.

That is, the supply drive shaft 148 of the spray unit u can be separated from the drive transmission mechanism on the frame 53 side at the portion of the unit clutch 178. When the unit clutch 178 is configured as the engaging clutch, it becomes unnecessary to separate the mechanism for transmitting the driving force when the spraying unit u is removed from the frame 53, ) Can be easily removed.

As described above, the unit-side clutch operation lever 180 and the frame-side clutch operation lever 185 are disposed close to each other (not mechanically connected). Therefore, the unit-side clutch operation lever 180 can be separated from the frame-side clutch operation lever 185. This makes it unnecessary to separate a mechanism (for example, a wire or the like) for transmitting the clutch operating force when the sprinkling unit u is removed from the frame 53, so that the sprinkling unit u can be easily removed .

On the other hand, in the conventional seedling box dispenser, since the supply portion can not be easily separated from the drive transmission mechanism on the frame side, the spray water hopper and the supply portion can not be removed together as a unit. Accordingly, in the conventional seedling box dispenser, only the spraying hopper can be separated so that the medicine remaining in the spraying hopper can be easily discharged. In such a configuration, there is a case where the spray hopper can not be firmly connected to the supply part, and rainwater infiltrates through a gap between the spray hopper and the supply part, and the medicine melts out. Further, since the supply part can not be removed from the frame, the medicine remaining in the supply part can not be easily discharged.

Thus, in this embodiment, the supply unit 55 can be easily separated from the drive transmission mechanism on the side of the frame 53 by configuring the spray unit and the drive transmission mechanism as described above. Therefore, the spraying unit u is formed by collecting the spraying water hopper 54, the supplying part 55, the shooter 147 and the like integrally so that the spraying unit u can be separated from the frame 53 for each spraying unit u will be.

Therefore, in the configuration of the present embodiment, in order to discharge the medicine remaining in the spray water hopper 54 and the supply unit 55, the spray unit u is removed and the lid unit 54a is opened so that each spray unit u Turn it over. Therefore, it is not necessary to configure the spray water hopper to be easily detachable from the supply portion as in the conventional seedling box dispenser. Thus, in this embodiment, the spray water hopper 54 and the supply case 55aa (55ab) are screwed. As described above, since the spray water hopper 54 and the supply case 55aa (55ab) can be firmly connected to each other, the sealability is improved and the rainwater or the like can not be easily introduced into the interior.

Next, a configuration for fixing each spraying unit u to the frame 53 will be described. As shown in Fig. 21, attachment stays 187 for loading the sprinkling unit u are disposed in the frame 53 at the attachment positions of the respective sprinkling units u. Each attachment stay 187 is composed of two leg portions 188 provided side by side in the left and right direction of the vehicle body and a plate-shaped horizontal portion 189 horizontally spread between the leg portions 188.

22 and 23, the round rod member 127 and the plate-like member 128 provided in the spray unit u are respectively disposed in the left-right direction of the vehicle body (the supply drive shaft 148) As shown in Fig. When the spray unit u is placed on the attachment stay 187, a rod-like member 127 is placed on the leg portion 188 and a plate-like member 128 is placed on the horizontal portion 189, respectively. Thereby, the spray unit (u) can be supported by at least three points by the two leg portions (188) and the horizontal portion (189), so that the posture of the spray unit (u) can be stabilized.

21, an inclined portion 188a and a U-shaped portion 188b formed continuously to the lower end of the inclined portion 188a are formed in the leg portion 188, respectively. With this configuration, when the spray unit u is placed in the attachment stay 187, the spray unit u is moved downward by its own weight while the bar member 127 is brought into contact with the inclined portion 188a As shown in Fig.

The bar member 127 is naturally guided by the inclined portion 188a and the bar member 127 is fitted inside the U portion 188b so that the spreading unit u is moved forward and backward As shown in Fig. In a state in which the spray unit u is positioned in the front-rear direction of the vehicle body, the clutch members 149 and 176 are positioned so as to face each other.

The horizontal portion 189 and the plate-like member 128 each have a certain length in the lateral direction of the vehicle body. That is, even if the position of the spray unit u deviates to some extent in the lateral direction of the vehicle body, the plate member 128 can be mounted on the horizontal portion 189. On the other hand, the distance between the two leg portions 188 is configured to be shorter than the length of the bar-member 127 in the lateral direction of the vehicle body. That is, even if the position of the spray unit u is shifted to some extent in the lateral direction of the vehicle body, the round bar member 127 can be placed on the two leg portions 188.

Therefore, even when the bar-like member 127 is placed on the leg portion 188 and the plate-like member 128 is placed on the horizontal portion 189 and the spray unit u is moved to some extent in the lateral direction of the vehicle body, It is possible to stably support the spray unit u at at least three points by the portion 188 and the horizontal portion 189. [ That is, the spray unit u is configured to be slidable in the lateral direction of the vehicle body (i.e., the direction in which the clutch members 149 and 176 contact or are spaced apart) while maintaining the posture of the spray unit u.

Therefore, for example, in a state in which the clutch members 149 and 176 are away, the spray unit u can be stably temporarily placed on the attachment stay 187. [ Since the spray unit (u) can be temporarily placed in this way, the spray unit (u) can be easily attached. Since the spray unit u is positioned in the longitudinal direction of the vehicle body in this temporary placement state (the state where the round bar member 127 is fitted in the U-shaped portion 188b), the spray unit u is positioned in the attachment stay It is possible to simply engage the clutch members 149 and 176 simply by sliding the clutch members 149 and 176 in the left and right directions of the vehicle body.

On the other hand, positioning of the spray unit u in the lateral direction of the vehicle body is carried out by forming convex portions 189a (see Fig. 21) formed in the horizontal portion 189 in the hole portion 128a (see Fig. 23) formed in the plate- Can be carried out. Further, a fixture (fixture) 190 is disposed in the vicinity of the attachment stay 187 (see Fig. 21). The fixing member 190 is configured to be able to hang and fix a hook member 127a (refer to FIG. 22) fixed to the round bar member 127. As shown in FIG.

The fastener 190 is configured to be able to easily switch between a state in which the hook member 127a is fixed by hooking and a state in which it is opened by one-touch operation (for example, with a single finger). Therefore, the spray unit u can be simply fixed to the attachment stay 187 by fixing the fixture 190 to the hook member 127a after positioning the spray unit u.

As described above, the attachment of the spray unit (u) can be completed only by fixing with the fixture (190). The clutch members 149 and 176 are engaged with each other only by attaching the spray unit u to the frame 53 (the state in which the supply drive shaft 148 and the drive transmission mechanism are connected). Thus, the attachment and detachment of the sprinkling unit u can be easily performed without screwing or attaching a driving mechanism or an operation mechanism of the clutch.

Next, a description will be given of a configuration for placing the removed raising and lowering stand 31a. Fig. 24 is a rear view showing a state in which the removed tumbler is worn. As described above, in the present embodiment, two pairs of raising and lowering rails 31a are configured to be detachable from the main raising rails 31. On the other hand, as shown in Fig. 21 and the like, the frame 53 is provided with a temporary placement stay 196 capable of placing and fixing the application unit u. 18, two provisional placement stays 196 are provided and are disposed near the right and left ends of the body of the frame 53, respectively.

When separating the raising and lowering rails 31a from the main raising and lowering rails 31, two spraying units u in the vicinity of the center of the vehicle body in the lateral direction of the vehicle body among the four raising units u are first set as the temporary raising stays 196 ) And fix it. Thereby, the space can be left at a position near the center in the lateral direction of the vehicle body. Then, the mother lifting base 31a is detached from the main mother lifting base 31 and is attached to the support pipe 197. 24, the raising and lowering table 31a attached to the support pipe 197 is disposed in a space formed by moving the two spraying units u at the center over the temporary placement stay 196. As shown in Fig.

The separated raising and lowering rails 31a are attached to the supporting pipe 197 and are disposed above the remaining main raising rails 31. [ Then, the raising and lowering stand 31a is in a position overlapping with the spraying unit u from the side view. If it is impossible to empty the space by moving the spray unit u, it is necessary to dispose the mother tray 31a and the spray unit u so that they do not overlap when viewed from the side So that the spraying unit u does not interfere). Therefore, in such a case, it is inevitable to place the attachment position of the attachment member 31a at a high position avoiding the application unit u, which makes it difficult to attach the attachment member 31a to the support pipe 197.

In this respect, in this embodiment, as described above, by forming the space by moving the spray unit u, it is possible to attach the mother tray 31a at a low position. Further, since the space is empty at the center of the vehicle body, the spray unit (u) is not disturbed at the time of attaching the mother runner (31a). This configuration can be achieved only by easily separating the spray unit u from the frame 53. [

As described above, since the spray unit (u) can be separated, for example, the separated spray unit (u) can be turned over and the medicine remaining in the spray water hopper (54) can be easily discharged. Since the spray water hopper 54 and the supply part 55 can be integrally handled together, it is not necessary to configure the spray water hopper to be detachable from the supply part like the conventional medicine spray device, And the supply part 55 can be improved. Further, it is also possible to store the unit for each unit with the spray unit u removed.

In the seedling box dispensing apparatus 51 according to the present embodiment, the frame 53 is provided with a drive transmitting mechanism for transmitting the driving force taken out from the rice cooker 1 to the vicinity of each spraying unit u By attaching the spray unit u to the frame 53, the supply drive shaft 148 and the drive transmission mechanism are connected. Thus, since the supply drive shaft 148 is connected to the drive transmission mechanism by attaching the spray unit u to the frame 53, the work of attaching the spray unit u to the frame 53 can be easily performed

In the seedlings box dispensing apparatus 51 according to the present embodiment, each of the spraying units u includes a unit side clutch member 149 fixed to one end of the supply drive shaft 148. In the frame 53, a frame side clutch member 176 for outputting the driving force transmitted by the drive transmission mechanism is disposed for each of the spray units u. The unit-side clutch member 149 and the frame-side clutch member 176 are engaged with each other so that the supply drive shaft 148 and the drive transmission mechanism are connected. Then, the unit side clutch member 149 can be separated from the frame side clutch member 176.

As described above, by providing the clutch corresponding to each of the spray units u, the presence or absence of the drive of the spray section u can be switched for each spray unit u. Since the spray unit u can be detached from the frame 53 at the engagement portion of the unit side clutch member 149 and the frame side clutch member 176 by configuring the clutch as the engagement clutch, It is possible to easily carry out the separation operation without labor to separate the drive transmission mechanism.

Since the engaging clutch can transmit the driving force only by bringing the clutch members 149 and 176 close to each other, the supply driving shaft 148 and the drive transmission mechanism are connected to each other only by attaching the spray unit u to the frame 53 The configuration can be realized simply.

Further, since the spray unit u can be slid with the attachment stay 187 as a guide and the spray unit u can be attached or detached, the positioning of the clutch members 149 and 176 can be easily performed . When the unit-side clutch member 149 and the frame-side clutch member 176 are engaged with each other (the state in which the supply drive shaft 148 is connected to the drive transmission mechanism) by fixing the spray unit u by the fixture 190 ).

Further, since the attachment stay 187 can maintain the posture of the spray unit u during attachment or separation, it is not necessary to support the spray unit u by hand so that it does not collapse during attachment or detachment work. It is also possible to once temporarily mount the spray unit u on the attachment stay 187 before the attachment work, for example. As a result, attachment or detachment of the spray unit u can be performed more easily.

Further, in the seedlings box dispensing apparatus 51 according to the present embodiment, the unit side clutch member 149 can be displaced according to the operation force of the clutch to switch the clutch. The spray unit u and the frame 53 can be separated from each other with the contact portion of the unit side clutch operation lever 180 and the frame side clutch operation lever 185 as a boundary. Thereby, it is possible to easily perform the separation operation without removing the work of separating the mechanism for operating the clutch when removing the spray unit (u).

Further, in the pancake unit 1 of the present embodiment, a space can be provided at a place where the spray unit u originally existed, by temporarily removing the spray unit u and putting it in the temporary placement stay 196. [ In this empty space, the separate raising and lowering rails 31a can be disposed.

The raising and lowering rails may be folded and stored as follows. Fig. 25 is a view for explaining an operation of folding a raising and lowering raising and lowering part of the molding part, and Fig. 26 is an A-arrow diagram of Fig. As shown in Fig. 25, for example, the mother stockers 31A to 31H are divided into four units. That is, the mother boards 31A and 31B are the first units, the mother boards 31C and 31D are the second units, the mother boards 31E and 31F are the third units, and the mother boards 31G and 31H are the fourth units .

On the other hand, the raising and lowering rails 31A to 31H are connected by locking the two connecting levers (lock levers) provided at the respective edge portions. A pipe-shaped stand S, which will be described later, is fixed to the left side edge portion of the parent resting section 31E and the right side edge section of the parent resting section 31F. Further, a pin (protruding portion R) fitted to the front end of the stand S is provided on the back side of the left end of the mother lifting base 31A and on the back of the right side end of the mother lifting base 31B. A tip end of the pin R and the stand S further includes a snap lock and is locked by the snap lock.

The spraying units 73A to 73D constituting each of the spraying units u are placed on a series of frames 53 and fixed by a snap lock or the like. The frame 53 is supported by brackets erected from the four eating-piece transmission cases 37. The frame 53 has a holding portion 53a similar to the stay 196 described above. The holding portion 53a is for temporarily placing each of the spraying units 73A to 73D.

Next, a description will be given of a method of folding the first units (the mother boards 31A and 31B) of the mother boards 31A to 31H to narrow the mother boards 31 after the completion of the food processing. The hopper unit 73C in front of the third unit (the raising and lowering stands 31E and 31F) is detached from the frame 53 and the holding portion 53a of the frame 53 (below the hopper unit 73D) And fix it with snap lock.

Then, in a state in which the mother lifting base 31A and the mother lifting base 31B are connected to each other, the connection between the mother lifting base 31B and the mother lifting base 31C is released. Specifically, the two connecting levers provided at the edge portion of the mother lifting base 31B are rotated in the releasing direction to release the connection between the mother lifting base 31B and the mother lifting base 31C. Next, the handles at both ends of the first unit (parent rests 31a, 31B) are gripped to move the first unit.

Then, the first unit is stacked on the third unit (parent rests 31E and 31F). Specifically, the two pins R provided in the first unit are respectively fitted to the ends of the pair of stands S provided in the third unit (Fig. 26). Next, it is locked by a snap lock which is not shown. The tip end of the key-shaped fixing pin provided at the left end of the third unit is fixed to the hole formed in the back surface of the first unit. Next, the receiving plate of the portion on which the first unit is placed is folded. By doing so, the width of the transfer station 1 becomes equal to or smaller than the width of the running vehicle body 10. Then, the car body 10 is transported on a truck or the like in a state where the carcass 1 is connected.

On the other hand, the first unit can be opened from the folded state by reversing the above procedure. Therefore, a detailed description will be omitted.

Next, a dividing panel (60) is provided in the whole of the mother lifting base (31) over the entire width direction of the mother lifting base (31). FIG. 27 is a side view of a molding part having a dividing panel, and FIG. 28 is a side view of a molding part having a dividing panel of another example. 27 (a) and 27 (b), the dividing panel 60 is formed of a metal plate (flat plate) having a predetermined rectangular thickness (the dividing panel 60 is not limited to a metal plate No plastic plate or the like). Both ends of the dividing panel 60 are fixed to the upper end of the bracket 61 fixed to the outer edge 31E of the raising and lowering table 31 with a pin 62 or the like.

On the other hand, the dividing panel 60 is preferably installed with an angle? With respect to the longitudinal direction D of the mother S placed on the mother lifting base 31 (that is, (Inclined at an angle? On the opposite side to the moving direction). The angle? Is an angle at which the dividing panel 60 opens the roots of the parent S to facilitate the supply of the drug P to the roots of the mother S, preferably 30 to 60 degrees do.

It is preferable that the width W of the dividing panel 60 is appropriately set in accordance with the difference in height of the various kinds of mother boards S placed on the mother board. For example, in consideration of the difference between the seedling seedlings (seedling seedlings) and the parent of ordinary growing, a dividing panel 60 of W = 50 mm is used. By doing so, the dividing panel 60 comes into contact with the upper part of the parent S even when the growth conditions are mixed together and the roots of the parent S are opened to reliably supply the medicine to the root of the mother S. There is a number.

Next, a description will be given of an operation of spraying the moire medicament through the thus-constructed rice plant. The mother S placed on the mother lifting base 31 is conveyed downward by the conveying belt B and when the mother S comes into contact with the dividing panel 60, the upper portion is bent backward in the conveying direction to form a space at the root portion . Through this space, medicines P are supplied from the respective spraying units u to the roots of the parent S. [

When the distal end portion of the prism S moves away from the lower end of the dividing panel 60, the prism S returns to its original standing state. In this manner, the parent S on the mother lifting base 31 is sequentially conveyed downward, and sequentially bent from the contact with the dividing panel 60 to form a space in its root. Then, the drug P is supplied to its root.

28 (a) and 28 (b) show another example of the present invention. In this example, two dividing rods 80A and 80B are provided in parallel at a constant distance L instead of one dividing panel as in the above example (the number of dividing rods is not limited to two , Three or more may be acceptable). On the other hand, the interval L between the two dividing rods 80A and 80B is set to about L = 50 mm. By replacing the dividing panel 60 with the dividing rods 80A and 80B, it is possible to provide a lighter and lighter formula while achieving the same effect.

In this example, both ends of the dividing rods 80A and 80B are fixed by welding or the like to the bracket 81 fixed to the outer side edge portion 31E of the raising base 31. [ On the other hand, the operation of spraying the drug P onto the parent S is the same as the above-mentioned example, and the description thereof will be omitted.
