Abstract

(57) [Summary] [Purpose] To make it possible for seeds to smoothly reach the feeding device even if the amount of remaining seeds in the hopper of the seeding device is large. A plurality of guide plates are alternately projected from the inner surface of the hopper 27 toward the center lower side above the plate plate 28 of the seeding device, and the tips of the guide plates are arranged so as to overlap each other.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the configuration of a hopper of a seeding device for flowers and vegetables.

[0002]

[Prior art]

 Conventionally, the hopper of a seeding machine for flowers, vegetables, etc. is placed above the feeding section to fill the seeds, and the shape is configured as a funnel shape with a thin lower part, and the seeds are dropped on the eye dish. By driving the plate, a certain amount of seeds were inserted into the seeding holes.

[0003]

[Problems to be solved by the device]

 If the hopper is funnel-shaped as described above, when the amount of remaining seeds in the hopper is large, the seeds will be clogged at the bottom of the hopper without a gap due to the weight of the seeds, and the degree of freedom of the seeds will decrease, and the eye dish will operate. Even if it was done, the seed did not move and the seed did not enter the seeding hole, and the part of the seeding hole would be fed in the air unless agitated, etc., and there was a problem that a stock was missing.

[0004]

[Means for Solving the Problems]

 The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described. In the hopper that supplies and stores seeds to the seed feeding part of the seeding machine, a plurality of guide plates are alternately projected from above the inner surface of the hopper toward the lower center of the hopper, and the tips of the guide plates are wrapped. It has been arranged.

【Example】

 The problems and solutions of the present invention are as described above, and the structure of the embodiment will be described with reference to the accompanying drawings. FIG. 1 is an overall front view of the soil filling device and the sowing device, FIG. 2 is a front sectional view of the sowing device, and FIG. 3 is a front sectional view of the sowing device showing another embodiment of the hopper.

Referring to FIG. 1, the overall configuration will be described. A carrier table 2 is placed on the leg 1, and roller conveyors 3, 3, ... Are mounted on the carrier table 2 at right angles to the traveling direction at appropriate intervals, and the roller conveyor 3 is driven by a drive motor. The tray 15 is placed on the roller conveyor 3 and conveyed. The soil filling device 4, the irrigation device 5, the pressure squeezing device 10, the seeding device 6, the soil covering device 7, and the irrigation device 9 are sequentially arranged on one side of the carrier table 2. The soiling device 4 is placed on the tray 15. Fill the soil in the recesses of the seedling raising pots 16 that have been placed, remove the excess soil and level it, the irrigation device 5 provides proper water, and the pressure suppressor 10 corresponds to the recesses of the seedling raising pot 16. A roller having a part is rotatably arranged, and a recess is formed on the surface of the soil so that the seed is located in the center of the pot while rotating the roller. The seeding device 6 drops seeds into the recesses to sow the seeds, covers the seed surface with soil by the soil cover device 7, and after leveling the seeds, gives water by the watering device 9.

As shown in FIG. 2, in the seeding device 6, a side plate 26 is erected on the carrier 2, a hopper 27 of the present invention is provided on an upper part of the side plate 26, and a pallet plate is provided at a lower end of the hopper 27. 28 are provided, and the seed plate 28 has seeding holes 28a, 28a ... Opened in the width direction corresponding to the number of recesses in the width direction of the seedling raising pot 6 on the tray 15. It is slidably arranged so as to be sandwiched between the pressing body 29 and the rollers 30, 30 provided on the lower surface.

An engaging portion 28b is provided on the lower right upper end of the plate plate 28, and a roller portion at an end of an arm 32 fixed to a pivot shaft 31 is fitted to the engaging portion 28b. The connecting link 33 is pivotally connected to the arm 32 fixed to the pivot shaft 31, and the other end of the connecting link 33 is connected to the arm 34 fixed to the drive shaft of the motor 25 to drive the motor 25. By doing so, the crank plate is moved so that the plate plate 28 can be slid back and forth diagonally. A seeding hole 28a is located at the highest position of the plate plate 28. A spring 35 for pushing out the seeds is arranged above the guide hole 28a, and a guide hose 36 for guiding the seeds to the tray 15 is provided below the spring 35. ing. 37 is a box for collecting seeds leaked from the hopper 27, 38 is a brush for removing excess seeds that did not enter the seeding holes 28a, 39 is a diaphragm provided on the back surface of the plate plate 28, and a leaf spring. By making it contact with 40, the leaf spring 40 and the vibration plate 39 are brought into contact with each other to vibrate in association with the sliding movement of the perforated plate 28 so that a bridge or the like cannot be formed and the seeding accuracy is improved. Of. Reference numeral 23 is a seeding switch.

The hopper 27 of the present invention projects the guide plates 20 and 21 downward in the center from the inner surface in the left and right direction, and the guide plates 20 and 21 are arranged in a labyrinth shape so that the guide plates 20 and 21 are inclined in opposite directions and the open side is lowered. However, the end portion on the open side is wrapped by the length L so that the seeds drop between the guide plate 20 and the guide plate 21. However, when the capacity of the hopper 27 is large, the number of guide plates is increased. With this configuration, when the seeds are filled in the hopper 27, the seeds are received by the guide plates 20 and 21, and the amount of seeds received by the eye plate plate 28 is reduced. The pressure received by the seeds is dispersed and becomes small, the freedom of movement when the seeds are paid out becomes large, the clogging and the bridge are reduced, and the seeds are surely inserted into the seed holes 28a.

It is also possible to configure the inside of the hopper 27 as shown in FIG. 3, and the hopper 28 ′ has an auxiliary hopper 24 arranged on the guide plate 22, and the auxiliary hopper 24 is configured in a funnel shape in a front view. Then, the lower pipe 24a and the guide plate 22 are arranged with a gap larger than that for allowing the seeds to pass therethrough, and when the auxiliary hopper 24 is filled with the seeds, the seeds fall further down to the perforated plate 28, Since the seeds falling from the auxiliary hopper 24 do not reach above the lower end of the pipe 24a, the amount of seeds on the perforated plate 28 is substantially constant, and the degree of freedom of seeds is increased and clogging is prevented as described above. It can be prevented.

[0011]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. In other words, the seeds will be received by the guide plate in the hopper of the seeding device, and even the seeds on the lower side will have a higher degree of freedom. It was possible to prevent bridging and improve seeding accuracy.
