Description

Rice seedlings of rice transplanter {SEEDLING REST FOR RICE-PLANTING MACHINES}

The present invention relates to the configuration of the mother loading zone of a passenger rice transplanter, and relates to a technique aimed at improving mobility and storage properties by reducing the left and right widths of the mother loading zone when moving or storing rice rice transplanters. In detail, the left and right sides of the mother loading stage are divided, the divided mother loading stage is detachably configured, and after completion of work, the divided mother loading stage is detached and placed on the mother loading stage on the fixed side to be combined. It's about the construction of a hostile zone.

BACKGROUND ART Conventionally, in a multi-paddy rice transplanter having an eight-core planter or more, a technique configured to fold a mother loading zone and a guide rail is known. For example, it is the technique of Unexamined-Japanese-Patent No. 10-127121. The reason for this configuration is that the width of the mother loading zone becomes wider in the multi-season rice rice transplanter, so that when transporting or moving, or storing rice rice transplanter in the warehouse, etc. This is because there was a problem that interferes.

In this prior art, the mother loading zone of two sets of left and right sides is divided into four groups of loading zones in the center, and when moving or storing, two sets of mother loading zones on both sides are respectively centered. It was configured to fold so as to be placed on the center of the mother loading stage while sliding slightly toward the rear. The left and right guide rails and the bumpers were configured to fold upward or forward.

However, since the conventional mother-base folding mechanism has a structure in which the slide mechanism is moved by the link mechanism (parallel movement), the mechanism is complicated and the cost is high. In addition, since the mother loading zones on both the left and right sides were folded toward the mother loading zone in the center, and the locks were locked to each other, the operation procedure was increased and the operation was complicated. Moreover, since only the folding baseband vibrates or shakes, it is necessary to lock and fix it, which is complicated and cumbersome.

The present invention provides a rice transplanter in which the length in the left and right width directions of the mother loading zone can be reduced, so that one or more sets of mother loading zones on one side or the left and right sides can be detached to be divided mother loading, and the division mother loading zone is the remaining. Since it is mounted on the upper side of the main mother band, it can be easily moved, transported, or stored in rice transplanters.

As the tide setting of the detachable divided mother loading zone, the width of the mother loading zone can be reduced more than the case where one division width is set when the divided mother loading zone is placed on the upper part of the main mother loading zone and accommodated. On the other hand, in too many tides, the weight of the divided mother loading zone becomes large. Thus, if two divisions of the mother loading zone do not require a large force to lift, the storing operation can be performed without difficulty.

Further, since the holding portions are provided on the left and right sides of the divided mother loading zone and one side of the left and right holding portions is disposed at a position higher than the other, the separation operation is easy and the structure is easy to put in force. By arranging the left and right gripping portions with the center of the divided basebands in between, it is easy to balance the lifting of the divided basebands, making it easier to work.

In addition, at least two supported portions are provided on the rear surface side of the divided mother loading zone in the left and right directions, and a support portion in the state of receiving the load in the gravity direction of the divided mother loading zone that is applied to this supported portion is installed on the mother loading surface side of the main mother loading zone. The upper base supporting portion is installed at a position higher than these supported portions on the back side of the divided mother loading stage, and on the mother loading side of the main mother loading zone. By installing an upper support portion for supporting the upper supported portion at a position higher than the support portion, it is to restrict the vibration as the divided mother loading zone rotates from side to side or back and forth. Since the lower support structure is a structure that receives the load in the gravity direction of the divided mother loading zone, the upper support structure has a simple and compact structure as described above to restrict the rotation of the divided mother loading zone.

Representatively, it is conceivable to have a structure in which two support portions at the lower left and right sides and an upper support portion at one upper side are provided on the rear side of the divided mother loading zones, and three supports are supported on the mother loading surface of the main mother loading zone.

Taking the three support structures as an example, as a specific example of the following two support structures, the supported portion of the divided mother band is a pin that protrudes substantially below the rear surface, and the pin is fitted to the main mother substrate. As a member, for example, there is provided a cylindrical member (support pipe) for inserting the pin in its axial center direction (approximately installed upward), or for providing a concave member for inserting the pin in its radial direction. You can think of it.

In particular, when the support portion of the main mother limb is composed of a cylindrical member, the two left and right pins of the divided mother limbs are easily inserted into each cylindrical member by varying the length of insertion into the respective cylindrical members. It can be supported by two cylindrical members. In other words, first of the two left and right pins, the pin with the longer insertion length is first inserted into the cylindrical member, and the pin and the supporting member then position the pin with the shorter insertion length with respect to the cylindrical member. Since it is a guide when inserting, it is possible to easily install and install the divided mother bands on the main mother bands.

The pivot shaft 65 is provided to protrude from the support plate 66a which is installed on the mounting plate 66. The attachment plate 66 has the same shape as the attachment plate 52, protrudes and installs the fixing shafts 66b and 66b for insertion into a hole (not shown) drilled through the rib 16a. 52 is fixed on the rib 16a (i.e., fifth from the left end of the main mother band 16M), as fixed to the rib 16a.

The above has described the member structure for mounting and fixing the divided mother loading zone 16D away from the main mother loading zone 16M on the main mother loading zone 16M, where the divided mother loading zone 16D is described. Locking for connecting and fixing both mother loading stages 16D and 16M in order to keep the mother loading stage 16 wide and wide, i.e., to keep the mother loading stage 16 wide and working. The apparatus 45 is demonstrated.

The lock device 45 is installed on the divided mother loading stage 16D corresponding to each of the lock rods 45a and lock levers 45b and a pair of lock rods 45a provided on the main mother loading stage 16M. It consists of a pair of lock cam 45c. 6, 17, and 18, the lower guide rails 18 and the upper guide rails 19 of the divided baseband 16D are provided in parallel with the pipes, respectively, and the lock rods in the pipes. The lock lever 45b is provided in the left end of each lock rod 45a, ie, the attachment side end of the half division base loading stand 16D, by inserting 45a. And the other end of each lock rod 45a protrudes to the right rather than the right end of the main mother loading stand 16M, and when attaching the division mother loading stand 16D to the right side of the main mother loading stand 16M, the said It is inserted in the lock cam 45c provided in the divided mother loading stage 16D. At the time of connection of both mother loading stages 16M * 16D, the lock rod 45b is rotated to one side, and it locks in so that the lock rod 45a may not come out from the lock cam 45c.

In the above-described configuration, a method of detaching the divided mother loading zone 16D and placing it on the main mother loading zone 16M and fixing it will be described. First, both lock levers 45b are rotated to the opposite side to the above, to release the lock of the lock rod 45a and the lock cam 45c, and to make it possible to detach the divided mother base 16D. Next, by holding the handles 40L and 40R, the divided mother loading zone 16D is moved to the right and removed from the main mother loading zone 16M, and then moved to the upper position of the main mother loading zone 16M.

Since the length difference between the fitting pins 41L and 41R is larger than the height difference between the supporting pipes 43R and 43L, first, the long fitting pin 41R is supported by the lower support pipe 43R on the right side. ) Into the As the support pipe 43R is low, the lifting height of the divided baseband 16D is small and the effort can be reduced. Next, the short fitting pin 41L is inserted into the support pipe 43L on the left side, but the fitting pin 41L is inserted after the fitting pin 41R is inserted into the support pipe 43R. Until the fitting pin 41L is positioned on the upper side of the supporting pipe 43L until the fitting pin 41L is inserted into the supporting pipe 43L, it is necessary to lift the split base plate 16D a little upwards. . However, since the fitting pin 41L is short, the lifting height is less completed, and the fitting pin 41R inserted into the support pipe 43R into which the fitting pin 41R is inserted is not removed. The support pipe 43R serves as a sliding guide for lifting up the split base material 16D while positioning the fitting pin 41L of the split base material base 16D above the support pipe 43L. In addition, it functions as a rotation point of the split base material base 16D, and the fitting pin 41L can be inserted easily and smoothly into the support pipe 43L.

When both of the fitting pins 41L and 41R are inserted into the support pipes 43L and 43R, the fitting pins 41L and 41R in the support pipes 43L and 43R are not fitted until the pin holes 41b and 43d fit. The position is adjusted, and a fixing pin is inserted into the pin hole 43d and 41b to prevent the fitting pin 41L and 41R from being pulled out. In this way, after receiving the weight of the split base material base 16D with the support pipe 43L * 43R, the coupling pin 44 is rotated last, and it connects to the engaging hole 42 of the front surface of the split base material base 16D. The fixing pin is inserted into the pin hole 44a to prevent it from falling out. The above operation restricts the rotation of the divided mother loading zone 16D in the front-back direction and the left-right direction, and is supported on the main mother loading zone 16M in three places, one above and two below.

In the above operation, as described above, one of the positions of the handles 40L and 40R is lowered (the left handle 40L is lower than the right handle 40R). It becomes easy to fit in the support pipe 43L, and it becomes easy to put in force when lifting and moving the splitting base stand 16D. Moreover, since the handle 40L * 40R is arrange | positioned to the left and right across the center G, it can move easily, without losing a balance at the time of a movement.

Next, another embodiment of the supporting configuration on the main mother loading zone 16M of the divided mother loading zone 16D that has been removed will be described. In the first embodiment shown in Fig. 12, the lengths of the fitting pins 41L and 41R are different from each other (in this embodiment, the fitting pins 41L on the left side are lengthened), and the height difference is provided at both lower positions. On the other hand, the upper ends of the support pipes 43L and 43R are set at the same height (that is, L1 = L2 with respect to the length of the insertion portion 43c shown in Figs. 8 and 9 above). When removing the divided mother loading stage 16D and placing it on the main mother loading stage 16M, first, a part of the long fitting pin 41L is inserted into the support pipe 43L, and then the fitting pin is placed. With the 41L as the point, the split base plate 16D is rotated to position the other fitting pin 41R above the supporting pipe 43R, and the fitting pin 41R is placed on the supporting pipe ( 43R).                 

In this case, the support pipe 43 of the same structure is also used as the support pipe 43L on the left side, without considering the relationship between the top and bottom difference between the support pipes 43L and 43R and the bottom height difference of the fitting pins 41L and 41R. It can also be used as the support pipe 43R on the right side, and the manufacturing process can be simplified.

3, 8, and 9 in which the upper and lower elevations are installed in the support pipes 43L and 43R, the fitting pins 41 to be inserted first are easily inserted into the support pipes 43. In the height difference within the range of the length difference of the left and right fitting pins 41L and 41R, as shown in FIG. 12, the long fitting pin 41 is inserted among the left and right support pipes 43L and 43R having the same height. It can also be said that the upper end position of the support pipe 43 was made lower than the other support pipe 43.

Next, a second embodiment of the supporting configuration on the main mother loading zone 16M of the divided mother loading zone 16D shown in Figs. 13 and 14 will be described. This means that one of the two support structures of the lower left and right sides is to be fitted with the same pin in the support pipe, and the other is to be fitted with the pin in the recess.

As shown in FIG. 13, the length of the fitting pin 41L * 41R and the height of the upper end of the support pipe 43L * 43R are equal, and as shown in FIG. 14, one side of the left-right support pipe 43L * 43R is shown. (In the present embodiment, the right support pipe 43R) opens the rear surface of the upper pipe portion corresponding to the insertion portion 43c, and both sides of the opening portion allow the fitting pin 41 to easily enter from the opening portion. They are widened at wide angles to form guide portions 43e and 43e. In this way, the rear opening-shaped U-shaped recess is formed in the axial direction, and the fitting pin 41 is received. In addition, in order to prevent the fitting pin 41 inserted into the recess, the release preventing pin 67 is inserted into the guide portion 43e and 43e in the direction perpendicular to the axis of the support pipe 43. To make it possible. However, the fall prevention pin 67 can also be inserted into the pinhole 43d and the pinhole 41b as described above.

Thus, in this embodiment, the insertion portion 43c of the support pipe 43L on the left side has the same pipe structure as the above-mentioned embodiment, and is rearward to the portion corresponding to the insertion portion 43c of the support pipe 43R on the right side. An opening-shaped recess is formed. When the divided mother loading zone 16D is removed and placed on the main mother loading zone 16M, first, the fitting pin 41L is moved in the axial direction thereof and inserted into the support pipe 43L. The positioning pin 41R is positioned so as to be parallel to the main mother band 16M in the left and right direction with the fitting pin 41L as the point, and the fitting pin 41R is guide part 43e and 43e. The fitting pin 41R is inserted into the concave portion of the support pipe 43R only by slightly moving in front of it, and moving forward, that is, only slightly moving in the radial direction of the fitting pin 41R. After that, the fitting pin 41R is fixed to the recessed portion of the support pipe 43R by the release preventing pin 67. In this way, the fitting pins 41L and 41R and the support pipes 43L and 43R are fitted to receive the load of the divided baseband 16D. Then, the coupling pins 44 are rotated to engage the tabs 42. It inserts into the hole 42a and fixes it, and prevents rotation of the division base material stand 16D.

Next, a third embodiment of the supporting configuration of the divided mother loading zone 16D to the main mother loading zone 16M shown in Figs. 15 and 16 will be described. On the rear surface of the divided mother loading stage 16D, a pair of left and right rollers 70 having an axial center in the direction perpendicular to the rear surface is rotatably disposed. On the other hand, as shown in Fig. 15, the rails 71 in the left and right horizontal directions rotatably coupled to the pair of rollers 70 at the upper side of the base surface of the main base stage 16M is the main base stage 16M. It extends to the right side from the left and right center part of (), ie, the attachment side of the division base material stand 16D. The right end is located substantially above the right end of the main base material stage 16M, and one end of the folding rail 71a is pivoted on the right end of the rail 71. This folding rail 71a is extended on the extension line of the said rail 71 at the time of storing the divided mother loading stand 16D on the main mother loading stand 16M, and is folded like the virtual line of FIG. It is supposed to be. In addition, it is assumed that the main mother loading zone 16M and the division mother loading zone 16D are connected and fixed by the lock device 45 as described above.

In such a configuration, when narrowing the width of the mother loading table 16, first, the lock by the locking device 45 is released, and the upper portion of the divided mother loading table 16D is rotated to the rear to fold the rail 71a. Folds. Then, by slightly lifting the divided base material loading stand 16D, placing the rollers 70 and 70 on the rails 71, and jumping the lower portion of the divided base material loading stand 16D, the top of the main base material loading stand 16M is raised. To move. At this time, since the load of the divided base material base 16D is hung on the rail 71 via the roller 70 * 70, it can move easily and lightly. When the lock is performed by a lock device (not shown), the divided mother loading stage 16D can be placed on the main mother loading stage 16M and fixed.

Finally, the wiring structure between the main mother band 16M and the divided mother band 16D will be described. In the main mother loading zone 16M and the division mother loading zone 16D, as shown in Figs. 3 to 5 and 18, the flasher lamp 54 and the mother relay sensor 55 are disposed, respectively, The flasher lamp 54 and the bus relay sensor 55 of the stage 16D are configured to supply power from the main mother loading stage 16M and to transmit a control signal.

As a power supply structure from the main baseband to the split baseband, in the baseband structure having a conventional folding baseband, a stretched curled cord is used or the cord is provided with a margin. Although folding of the split base pile was allowed by wiring, when the cord was folded or set in the working state, the cord was easily caught by other parts, and there was a risk of damage. Also, as a maintenance, the range in which the divided mother loading zone can move even if the divided mother loading zone is separated from the main mother loading zone has been determined by the code.

Like the mother loading zone 16 of the present invention, if the divided mother loading zone is detachable, the problem of being caught or damaged is further increased by requiring a margin of the cord. Even when the split mother loading zone is attached to and detached from the main loading zone, it is necessary to make the coupling portion of the cord waterproof, and the replacement is complicated.

Therefore, in the rice transplanter of the present embodiment, as shown in Fig. 17, the side ends of the divided mother loading zone 16D and the main mother loading zone 16M, that is, the joining portions of both mother loading zones 16D and 16M, are shown. The outlet type connectors 60a and 60b are respectively disposed in the sockets, and the cords connected to the flasher lamp 54 and the relay relay sensor 55 are connected to the connector 60a to be installed on the split base plate 16D. have. In addition, these connectors 60a and 60b are waterproof. With this configuration, the divided mother loading zone 16D can be separated only by moving to the side (right side), and the wiring can also be connected by setting to the working state only by moving to the reverse direction (left side). Thus, there is no tangle of cords and no risk of breaking.

In addition, as shown in FIG. 18, the lock device 45 can also be used as a contact point. In other words, the ground wire wire is wired to the main matrix stage 16M, and the contact for power supply to the two pairs of relay sensors 55 provided in the divided matrix stage 16D is connected to the lock cam 45c. 45c). In the divided mother loading zone 16D, the lock rod 45a consisting of two metals at the upper and lower sides is used as a conductive member to each of the mother relay sensors 55 (preferably, the surface of the lock rod 45a is made invisible). And a parent relay sensor 55 is connected to each lock rod 45a. Therefore, when the two lock rods 45a are inserted into the lock cam 45c, respectively, and the divided mother loading stage 16D is mounted on the main mother loading stage 16M, two of the divided mother loading stages 16D are simultaneously present. The conducting wire for the mother relay sensor 55 is connected to the earth side conducting wire of the main mother loading zone 16M.

Moreover, in the Example of the mother loading stand 16 shown in FIG. 18, the positioning member 56d * 56m at the time of attaching the divided mother loading stand 16D to the main mother loading stand 16M, respectively, is divided. 16D and the opposite side end of the main base material stage 16M are provided in a shape facing each other, and the contact points provided on the positioning members 56m of the main base material stage 16M are connected to the flasher lamp 54. It is also used as a contact for power supply, and the earth-side conducting wire of the flasher lamp 54 is wired to the said main baseband 16M. In this manner, when the divided mother loading zone 16D is set in the main mother loading zone 16M in the working state as described above, the flasher lamp 54 of the divided mother loading zone 16D and the two mother relay sensors are locked. (55) is conducting. If the lock is inadequate, an alarm is generated in the operating section of the rice transplanter because the mother relay sensor 55 of the divided mother loading zone 16D is cut off without conduction.

As mentioned above, the mother loading stage of the rice transplanter which concerns on this invention can be used for the rice planting machine of 8 planters, or the rice planter of the other plants of 8 tanks, and at the time of the movement, conveyance, and storage of these rice planters. It will work.
