[0002]

[Prior Art]

 Conventionally, this kind of suction type seeder is provided with a substrate having a mounting surface on which a tray can be mounted and a suction box having a suction chamber, and one side of this suction box communicates with the suction chamber. With a seeding plate having a plurality of suction seeding ports attached, the suction box can be moved up and down with respect to the base body via a supporting member, and the seeding position where the suction seeding port of the seeding plate is directed downward, While supporting the suction position facing upwards so as to be rotatable, a suction device is provided so that the suction device communicates with the suction chamber via a suction passage. Further, on one side of the suction seeding surface where the suction seeding mouth is formed in the seeding plate, a seed tank having an opening portion opened toward the seeding surface is provided, and the opening portion of the seed tank is It is formed so that it is higher at the seeding position and lower at the suction position.

When performing the seeding work, the whole of the suction box is moved upward with respect to the base by the support member to mount the tray on the mounting surface of the base body, and at the same time, the support member described above. On the other hand, the suction box is normally rotated 180 degrees in one direction with respect to the seeding position, that is, the suction box is turned 180 degrees to the suction position where the suction seeding port of the seeding plate faces upward. At this time, since the open part of the seed tank is located on the lower side at the adsorption position, the seeds in the seed tank are directed upward from the open part on the suction sowing surface of the sowing plate. Since the suction force of the suction machine is applied to the suction chamber through the suction passage, the seeds are respectively sucked into the suction seeding ports of the seeding plate by the suction action of the suction chamber. Adsorbed.

As described above, after the seeds have been adsorbed to the suction seeding openings of the seeding plate, the suction seeding openings of the seeding plate are rotated while rotating the suction box 180 degrees in the opposite direction to the above case. It is reversed to the seeding position that faces downward. At the time of this reversal, the seeds not adsorbed to the suction and sowing mouths are returned from the opening to the seed tank, and when the suction box is reversed to the sowing position, the opening of the seed tank is turned up. Since the seed is returned to the seed side, the seed returned to the seed tank is stored in the seed tank without dropping from the opening. Also, after the suction box is inverted from the suction position to the seeding position, the suction box is moved to a position above the tray via the support member, and the suction chamber is opened to the atmosphere. The seeds adsorbed to the suction seeding ports of the seed plate are sown in the pot portions of the tray.

[0005]

[Problems to be solved by the device]

 However, in the above suction type seeding machine, the seeding plate having the suction seeding mouth is provided only on one side of the front and back sides of the suction box and is screwed, so that the suction of seeds to the sowing mouth is performed as described above. After seeding at the seeding position, it will be performed only after rotating 180 degrees and reversing to the suction position, so the work efficiency is poor and only the seeding work of 50 to 100 trays per hour can be done. It was

[0006] The present invention provides suction except when adsorbed at the adsorption position and inverted to the seeding position, and when seeding ends at the seeding position and is inverted to the adsorption position, that is, when seeding is performed at the seeding position. Focusing on the fact that the machine is rolled and the suction force acts on the suction sowing port, the suction force during this time can be used to adsorb the seed to be seeded next time, and its working efficiency is The purpose is to provide a suction-type seeder that can be doubled or nearly doubled and can improve work efficiency.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a base body 1 having a mounting surface 10 on which a tray T can be mounted, and a suction chamber 21, and can move up and down with respect to the base body 1 and can roll. In the suction type seeder having the suction box 2 supported on the suction box 5, the suction machine 5, and the suction passage 50 that connects the suction box 5 and the suction chamber 21, the front and back surfaces of the suction box 2 are A front suction seeding port 22a and a back suction seeding port 22b which are open to the suction chamber 21 are provided.

[0008]

[Action]

 Since the front and back suction seeding ports 22a and 22b are provided on both the front and back sides of the suction box 2, for example, when the front side suction seeding port 22a is located at the suction position directed to the upper side, the back side suction seeding port 22b is It is located at the seeding position that is oriented toward the lower side, and this back suction seeding port 22b is inverted downward and moved to the seeding position to start seeding. It is adsorbed.

Therefore, when the seeds adsorbed to the back side suction sowing port 22b are sowed and the back side suction sowing port 22b is inverted upward, the seeds are adsorbed to the front side suction sowing port 22a. It is possible to perform seeding from the front suction seeding port 22a by moving the suction box 2 downward immediately after reversing without waiting for adsorption.

As a result, the work efficiency is almost doubled as compared with the conventional example in which the suction seeding port is provided only on one side of the suction box.

However, the suction member 5 and the suction chamber 21 may be directly connected to each other via a suction hose without forming the support member 3 with a hollow member.

Therefore, in the suction type seeder as described above, the front side suction seeding port 22a and the back side suction seeding port 22b opening to the suction chamber 21 are provided on both front and back sides of the suction box 2, and While rotating the suction box 2 in the same direction, the adsorption of seeds and the sowing of the adsorbed seeds on the tray can be performed alternately on the front and back surfaces of the suction box 2.

More specifically, as shown in FIGS. 1 and 2, the suction box 2 includes front and rear walls 20a facing each other, and a continuous extension from the ends of the front and rear walls 20a. A pair of front and back seeding plates 22A and 22B made of a front and back open box-shaped main body 20 having opposite side walls 20b and color aluminum plates detachably attached to the open parts of the box-shaped main body 20. The suction chamber 21 is provided between the front and back seeding plates 22A, 22B and the box body 20, and each seeding plate 22A, 22B has a plurality of front and back surfaces that open to the suction chamber 21. Suction seeding ports 22a and 22b are bored. In addition, suction seeding surfaces 22c and 22d recessed on the side of the suction chamber 21 are provided in the center of the seeding plates 22A and 22B, and the front and back suction seeding surfaces are respectively attached to the suction seeding surfaces 22c and 22d. The mouths 22a and 22b are formed, and seed tanks 23, which will be described later, are provided on one side in the front-rear direction of each of the suction seeding surfaces 22c and 22d.

Further, the suction box 2 is rotatably supported by the cylindrical shafts 43, 43 of the swinging part 40 on both side walls 20b, 20b of the box-shaped body 20, and the front and rear of the box-shaped body 20.

The seeds adsorbed on the front and back suction seeding openings 22a, 22b of the seeding plates 22A, 22B are released for seeding. The closing portions 24, 24 are swingably supported by the front and rear walls 20a, 20a via hinges 24b, and are normally biased by a spring 24c to close the opening hole 24a.

Further, as shown in FIGS. 1 and 2, the various child tanks 23 provided on the seeding plates 22A and 22B have inner walls 23a facing the suction seeding surfaces 22c and 22d and both side walls 23b and 23b. The outer wall 23c and the upper and lower opposing walls 23d and 23e are formed into a substantially rectangular cross section extending in the width direction of the seeding plates 22A and 22B, and the facing wall 23d of the various child tanks 23 is connected to the seeding plates 22A. , 22B are integrally formed continuously with the inclined walls 22e, 22e extending from the suction sowing surfaces 22c, 22d, so that the seed tanks 23 project outward at one end of the sowing plates 22A, 22B. Form as a unit in the state.

The inner walls 23a of the various child tanks 23 are formed with open portions 23f that open toward the suction seeding surfaces 22c and 22d of the seed plates 22A and 22B, respectively, and the tip ends of the inner walls 23a. Each side is integrally provided with a slanting portion 22g that is slanted toward the inner side of the tank, and each suction portion 22g directs the suction box 2 in the direction of the arrow in FIGS. It is arranged to prevent the contained seeds in the various child tanks 23 from falling and discharging from the opening 22f to the outside when they are rotated.

Then, as shown in FIG. 2, for example, the entire suction box 2 is turned to the adsorption position where the front seeding plate 22A is facing upward, and the seeds are put into the front suction seeding opening 22a. In order to supply and adsorb the seeds, the open portion 23f of the seed tank 23 is positioned on the lower side, and the opening 23f is passed through the inclined portion 22g and the inclined wall 22e to the suction seeding surface 22c of the front seedling plate 22A. The seeds in the seed tank 23 are dropped and supplied, and the suction force of the suction chamber 21 causes the seeds to be adsorbed to the front suction seeding port 22a. Also, after sowing by dropping the seeds from the back suction seeding mouth 22b that has adsorbed the seeds in the previous stage, the suction box 2 is rotated in the direction of the arrow in FIG. 2 so that the front suction seeding mouth 22a faces downward. The seeds which are not adsorbed to the suction seeding port 22a when they are positioned are returned to the seed tank 23 through the opening 23f. Further, as shown in FIG. 2, when the front seedling plate 22A is turned to the upward suction position, the back seeding plate 22B faces downward and is positioned at the seeding position. The opening 23f of the seed tank 23 provided in the back side seeding plate 22B is located on the upper side to prevent the stored seeds in the tank 23 from falling and discharging from the opening 23f to the outside. , After sowing the seeds adsorbed in the back suction seeding port 22b, when rotating the suction box 2 in the direction of the arrow in FIG. 2 to place the back suction seeding port 22b in the upward facing suction position. The inclined portion 23g provided at the tip of the inner wall 23a prevents the seeds stored in the seed tank 23 from falling out from the open portion 23f and discharged, but on the way to the suction position. In the process in which the seeds in the seed tank 23 are supplied onto the adsorption seeding surface 22d of the back seeding plate 22B and the seeds are sown from the front suction seeding opening 22a which is turned downward by the inversion, that is, It is sucked to the back side suction seeding port 22b in the process of rotating the suction box 2 down to the seeding position to stop the suction device 5 and opening the closing part 24. In this case, even if the suction to the back side suction seeding port 22b is not completely completed, the closing plate 24 is closed after the seeding is completed, and the suction device 5 is driven to apply suction force. The suction can be completed in the process of moving up the suction box 5 and reversing it.

That is, the seeds can be adsorbed to the suction seeding port 22a or 22b after seeding in the process from the completion of one seeding to the repositioning to the seeding position. This eliminates the need for waiting time and improves the work efficiency.

Next, the operation of the suction type seeder having the above configuration will be described. First, when performing a sowing operation, the operation switch 16 is turned on to drive the suction device 5, and the pipe 31, the elbow pipe 32, the flexible hose 44, the cylindrical shaft portion 42b, and the forked portion 42a are connected. The suction force of the suction device 5 is applied to the suction chamber 21 through the suction passage 50 formed by the air passage 40a and the hollow portion 43a of the cylindrical shafts 43, 43. The suction action is exerted on each suction seeding port 22a.

Then, the suction box 2 is swung upward from the seeding position shown by the solid line in FIG. 1 with respect to the base body 1 via the swinging portion 40 as shown by the virtual line in the figure. Under such a state, the tray T is mounted on the mounting surface 10 of the base body 1 at a predetermined position via the guide pin 11.

Next, the suction box 2 is rotated in the direction of the arrow in FIG. 1 at the upward swing position, and as shown in FIGS. 2 and 4 (a), for example, the front seedling plate 22A is turned upward. To the adsorption position. In this process, the open portion 23f of the seed tank 23, which is integrally provided on the front seedling plate 22A, is located on the lower side, and the seeds in the seed tank 23 are fed from the opening 23f to the front seedling plate 22A. It is dropped and supplied to the suction seeding surface 22c through the inclined wall 22c. At this time, since the seeds are adsorbed to the back side suction seeding port 22b as described below, the seeds are moved down immediately after the inversion without waiting for the adsorption on the front side suction seeding port 22b. In the process, by the suction operation of the suction chamber 21 provided to each suction seeding port 22a of the front side seeding plate 22A, seeds located near each suction seeding port 22a are adsorbed to each suction seeding port 22a. Is done.

Then, as shown in FIG. 1, first of all, the front end portion of the suction box 2 is moved to the front position as shown in FIG. The seed tank 23, which is supported by the rear receiver 11 and integrally provided on the rear side of the suction box 2, is placed and supported on the upper side of the rear receivers 13, 13. Then, the operation switch 16 of the suction device 5 is turned off to stop the suction by the suction device 5, and at the same time, the closing part 24 is opened to open the inside of the suction chamber 21 to the atmosphere. The seeds adsorbed to the suction seeding ports 22b of the back side seeding plate 22B are desorbed and seeded in the pots P of the tray T, respectively. By opening the closing portion 24 to release the adsorption of the seeds adsorbed on the front suction seeding port 22a, the box-shaped main body is opened via the front suction seeding port 22a from which the seeds have been removed. Although the suction chamber 21 in 20 is opened to the atmosphere, since the diameter of the suction seeding port 22a is small, the suction force in the suction chamber 21 is not greatly impaired, and suction is not performed after seeding. Since the machine 5 is driven and the air opening hole 24a is closed, the adsorption of seeds is hindered by the front suction seeding port 22a of the front seeding plate 22A provided on the opposite side of the back seeding plate 22B. There is nothing to be done.

Further, after the seeding work from the back side suction seeding port 22b is completed as described above, the suction box 2 is inverted in the arrow direction of FIG.

That is, the position (a) in FIG. 4 is reversed to the position (e), and the front seedling plate 22A is directed downward.

In this case, when the front suction seeding plate 22A moves to the position (c) beyond the position (b) in FIG. 4, only the seeds that have been adsorbed to the front suction seeding port 22a remain and the seeds that have not been adsorbed remain. Seeds are returned to the seed tank 23, and seeds are supplied from the seed tank 23 when the back suction plate 22B, which has finished sowing, moves to the position (e) beyond the position (d) in FIG. From the position shown in FIG. 4 (e) until the suction box 2 moves down to the seeding position and seeding is started from the front side suction seeding port 22a, that is, until the suction device 5 is stopped. The seeds supplied to the back side seeding plate 22B by the suction force from the suction device 5 are adsorbed to the back side suction seeding port 22b.

As described above, since the front and back seeding plates 22A and 22B having the front and back suction seeding ports 22a and 22b are provided on both the front and back surfaces of the suction box 2, the suction box 2 is shown in FIG. While rotating in the same arrow direction, when the front side seeding plate 22A is located at the adsorption position that directs to the upper side, for example, the back side seeding plate 22B is located at the seeding position that directs to the lower side. The seeds are adsorbed to the front suction seeding opening 22a in the process of turning the seeding opening 22b downward, moving it downward to the seeding position and starting seeding.

Therefore, when seeds adsorbed on the back side suction sowing port 22b are sown and the back side suction sowing port 22b is inverted upward, the seeds are adsorbed on the front side suction sowing port 22a. It is possible to perform seeding from the front suction seeding port 22a by moving the suction box 2 downward immediately after reversing without waiting for adsorption.

As a result, the working efficiency is almost doubled as compared with the conventional example in which the suction seeding port is provided only on one side of the suction box. In the above description, the case of rotating in the same direction has been described, but it is needless to say that it is possible to alternately perform half rotations instead of rotating once in the same direction.

In the embodiment shown in each drawing, one suction chamber 21 is provided in the suction box body 20, and the front and back suction seeding ports 22 a communicating with the suction chamber 21 are provided at the front and back openings of the suction box body 20. The front and back seeding plates 22A and 22B each having a suction plate 22a and 22b are attached to each other. In the present invention, a partition plate is provided in the suction box body 20, and two suction chambers 21 are provided in a defined manner. The front and back seeding plates 22A and 22B may be attached to the open sides of the respective suction chambers 21. In this case, for example, a switching valve may be provided in the middle of the suction passage 50 to It is preferable to selectively communicate the suction chambers 21 with the suction passages 50 by a switching operation such as a switching valve.

[0037]

[Effect of the device]

 As described above, according to the present invention, the base 1 having the mounting surface 10 on which the tray T can be mounted, and the suction chamber 21 are supported so as to be movable up and down and rotatable. In a suction type seeder equipped with a suction box 2, a suction machine 5, and a suction passage 50 that communicates the suction machine 5 with the suction chamber 21, the suction chamber 21 is provided on both front and back surfaces of the suction box 2. Since the front side suction seeding port 22a and the back side suction seeding port 22b which are open to the inside are provided, for example, when the front side suction seeding port 22a is located at the adsorption position pointing to the upper side, the back side suction seeding port 22b is located on the lower side. The seeds are sucked into the front suction seed sowing mouth 22a in the process until the back suction seed sowing mouth 22b is inverted downward and moved to the sowing position to start sowing. Than it is.

Therefore, when seeds adsorbed to the back suction seeding port 22b are sown and the back suction seeding port 22b is inverted upward, the seeds are adsorbed to the front suction seeding port 22a. It is possible to perform seeding from the front suction seeding port 22a by moving the suction box 2 downward immediately after reversing without waiting for adsorption.

As a result, the work efficiency is almost doubled as compared with the conventional example in which the suction seeding port is provided only on one side of the suction box.
