Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a seeding machine used for sowing seeds in rows or in a dotted manner onto a soil bed loaded in a seedling nursery box.

This type of seeding machine has a seed arranging plate with seed insertion openings formed at regular intervals above the seedling box, and a seed storage hole with seed storage holes formed at regular intervals similar to the openings. A seeding device made by overlapping a regulatory frame is placed,
The seeding device is moved relative to the seeding plate and the regulating frame in the horizontal direction, so that the first state in which the opening and the storage hole are misaligned in the horizontal direction matches the closed part and the storage hole. There is a device that is configured to be able to switch freely to a second state in which seeds are stored in a predetermined amount in the storage hole in the first state, and in the second state, the seeds are passed through the opening and sown in an aligned manner on the bedding. According to this configuration, since a predetermined amount of seeds are stored in the storage hole, there is an advantage that it is possible to carry out aligned sowing with a constant amount of seeds.

The present invention aims to promote automation in the above-mentioned seeding machine to save labor. Embodiments of the present invention will be described in detail below with reference to illustrative drawings. The figure shows two seedling boxes stacked in parallel on a conveyor belt supported at a constant height.

A seed line extraction device 4 is disposed above a predetermined seedling growing box 2' (the one located at the left end in the illustrated diagram) among the seedling growing boxes 2.

This seed dispensing device 4 connects and supports a horizontal frame 7 via a hydraulic cylinder 6 to a supporting frame 5 that is stably grounded so that it can be driven up and down, and rollers 8 are attached to the horizontal frame 7. A hopper 9 in which seeds W are stored is suspended and supported through the hopper. The driving roller 8' of the rollers 8...
The hopper 9 is connected in conjunction with an electric motor 0 that can be freely switched between forward and reverse rotations, so that the hopper 9 can be moved horizontally and backwards along the upper part of the seedling box 2' with a constant stroke. ' is provided with a lid 11 for opening and closing this outlet 9'. This lid body 11 is pivotally connected to a swinging arm 13 which is pivotally supported by the hopper 9 and is stably switched and held by a spring 12, and protrusions 13a extending left and right from this swinging arm 13. , 13b are configured to be switched between an open state and a closed state as the bushing pieces 5a, 5b attached to the support frame 5 are pressed against each other. A frame 7' attached to the horizontal frame 7 is provided between the seedling raising box 2' and the seed line extraction device 4.
The seeding device 14 is connected and supported by...

This seeding device 14 includes a seed alignment seeding plate 15 that is fixedly connected to the frame 7', and a seed alignment plate 15 that is fixedly connected to the frame 7'.
' is equipped with a horizontally movable hydraulic cylinder 1.
As shown in FIG. A gate part 15' is formed, and the seed amount regulating frame 17 includes:
Seed storage holes 17 in the form of long grooves having a constant height at regular intervals in the same manner as the seed insertion closing part 15'.
′... is formed. Then, the seeding board 15
The regulating frame 17 is placed on top in a first state in which the seed insertion opening 15' and the seed storage hole 17' are horizontally shifted, and in this state, the seeds W to be discharged from the hopper 9 are Once a certain amount is stored in the storage holes 17'..., the regulating frame 17 is moved horizontally, and the storage holes 17'...
. . , so that seeds are sown in rows on the soil bed 3 through the opening 15' when the opening 15' is switched to the second state in which the closing part 15' and the closing part 15' are aligned with each other. In addition, the outlet 9 of the hopper 9
A brush 18 is provided on the side of the regulation frame 17 to remove excess seeds W on the frame 17 as the hopper 9 moves. It is configured as follows. The hopper 9 is provided at the left end of the support frame 5.
Four IJ limit switches 19a... are installed, and these limit switches 19a...
An electric signal from one IJ mitt switch 19a is transmitted to the hydraulic cylinder 6 via a required control circuit (not shown), and an electric signal from one IJ mitt switch 19b is transmitted to the electric cylinder 6 through a required control circuit (not shown). An electric signal from one glue mitt switch 19c is transmitted to the motor 10, and an electric signal from one glue mitt switch 19d is transmitted to the electric motor 20, which is interlocked with the conveyor belt 1. It is configured to be

Then, when the hopper 9 moves to the left from the state shown in FIG. 1 and FIG. As each limit switch 19a... is brought into contact as shown in FIG. , as shown in FIG.
. . . from the first state to the second state where the gate part 15' matches the
A mechanism 21 for switching to the state is configured, and this switching mechanism 21
The seeding apparatus is configured to carry out the above-mentioned row-aligned seeding when activated.

Further, after the end of sowing, an electric signal from the limit switch 19a is transmitted to the hydraulic cylinder 6, and the rattan frame 7 is lifted as shown in FIG. is transmitted to the electric motor 10', the electric motor 10 is rotated in the opposite direction, and the hopper 9 is moved backward, and at the same time, the electric signal from the limit switch 19d is transmitted to the two electric motors, as shown in FIG. The conveyor belt is driven as shown in FIG. The horizontal frame 7, which has been lifted as shown in the figure, starts to descend due to the extension operation of the hydraulic cylinder, and the second
At the same time as it descends to the predetermined lowering position as shown in the figure,
The hopper 9, which had been moving backwards as described above, reaches the right end, and the drive motor 10 is again in the normal rotation state, and is configured to perform the above-mentioned sowing operation, so that the seeding operation is automatically continued in this order. Configured for sowing. In the embodiment of the present invention, the seed insertion closing portion 1 of the regulating frame 17 is
5'... is configured in a cylindrical shape, and as shown in FIG. It is difficult for the sown seeds W to be sown into the formed recesses a to be unexpectedly transferred.

Furthermore, in carrying out the present invention, various types of switching mechanism 21 can be considered. For example, in the case of the embodiment of the present invention, as shown in FIG.
The regulating frame 17, which is elastically biased toward the first state, is moved to the second state.
As shown in FIG. Switching may be performed by pressing the bush at a certain point.

Further, as in the embodiment, when the seed line extraction device 4 and the seedling growing box 2' are moved relative to each other, it is also possible to install the hopper 9 at a fixed position and gradually moving the seedling growing box 2'. It is.

Other forms may be used, such as a form having...

In short, in the seeding machine according to the present invention, in the seeding machine described above, the storage hole 17' is provided above the seeding device 14.
Distributing the device 14 for manipulating the seeds to ......, and
The device is characterized in that it is provided with a mechanism 21 that moves when the seed ray dispensing operation of the seed dispensing device 14 is completed to switch the sowing device 14 from the first state to the second state. When the seed line extraction operation is completed, the sowing device 14 automatically changes from the first state to the second state in conjunction with this.
Since the state can be changed over, there is no need for the operator to make this change, which simplifies the work and allows the sowing of the desired shape to be done uniformly and efficiently.
