Description

[Detailed Description of the Invention] The present invention provides a new simple seeding machine for seedling-raising containers that moves a seed chamber that moves on a seeding plate above a stationary seedling-raising container.

Conventionally, seedlings have been raised by sowing them in paper pots, plastic pots, and other various seedling-raising containers, but if the sowing is not done accurately, plants will be missing if they are continuously transplanted using a machine. For this reason, many seeding devices have been announced, but they can be roughly divided into two methods: manual seeding using a seeding plate, and seeding using a rotating seeding drum or vacuum seeding machine.
The former method is characterized by extremely high accuracy because the seeds are placed in holes drilled on the board and the seeds are sown while being constantly monitored by the human eye. However, since the work is done manually, it is an extremely inefficient method. On the other hand, the latter has the advantage of efficiency because it allows continuous sowing, but has the disadvantage of poor sowing accuracy.

This invention was developed as a result of research to develop a device that can efficiently sow seeds by taking advantage of the advantages of seeding plates.The machine frame of the seeding machine is divided into an upper stage and a lower stage, and a seeding board is stretched between the front and rear machine frames of the upper stage. A seed guiding frame is provided on both sides of the seeding plate, which can be moved along the upper machine frame.The seed guiding frame holds the seeding plate vertically, and a brush is hung horizontally above the seeding plate, and seeds are placed between the brushes. Adjustment chambers are formed on both sides of the storage chamber, and a seed holding plate is fixed to the lower part that connects the guide frames on both sides, and is brought into sliding contact with the lower surface of the seeding plate, and between the front and rear machine frames of the lower stage is a seedling container for transporting seedlings. A device is used in which a road and a seedling container stop plate are hung horizontally, seeds are placed in a chamber made up of the brush, the guide frame is moved, and the seeds are sown in the seedling container supported by the lower machine frame. It was resolved by this.

The present invention will be explained with reference to the drawings. Reference numeral 1 indicates an upper machine frame 2 and a lower machine frame, which form a pair and are parallel to each other. Further, the corners of the upper and lower machine frames are connected to each other by connecting rods 3 at the top and bottom. A seeding plate 4 is stretched and fixed between the upper machine frames 1 and 1, and a large number of seeding holes 5 are provided on one side of the seeding plate.
has been drilled. This seeding hole 5 is determined by the size of the seeds to be sown, the number of seeds to be sown, or the shape of the seedling raising container.
The holes are drilled as appropriate depending on the size, and for example, in the case of beet seeding plates, holes with a diameter of 2 to 4 mm are provided so as to correspond to each pot when the 1600 paper pots are expanded. Seed guide frames 6 are arranged on the outside of the pair of upper machine frames 1, 1, and each guide frame 6 is provided with two pairs of upper and lower guide rollers 7, 7, which can be rotated by shafts 8, 8... Attach to. and each pair of rollers 7,
7 vertically clamps the edges of the upper machine frame 1 so that the guide frame 6 can be moved laterally along with the upper machine frame 1. Further, a plurality of brush stops 9, 9, . . . are provided at the upper end of the guide frame 6, and the brush 10 is fixed between the guide frame 6 on the opposite side in the vertical direction with mounting bolts 11. The brush 10 has a horizontal rod 10 made of metal, wood, or plastic.
A and a brush 10-b made of resin fiber, and the length of the brush 10-b is usually 30 to 60 mm.
Also, the number of brush stops 9, 9 is usually 4 to 6,
Thus the chambers 12, 12 delimited by the brush 10
is 3 to 5. The central chamber is a seed storage chamber 12-a, and the chambers on its left and right are seed adjustment chambers 12-b.
That is. Further, the tip of the brush 10-b is always in contact with the upper surface of the seeding plate 4. Therefore, when seeds are introduced into the central chamber 12-a by the horizontal movement of the guide frame 6, the seeds enter the seeding hole 5 of the seeding plate 4, but hardly leak into the adjustment chamber 12-b. Therefore, by checking the state of the adjustment chamber 12-b, the filling status of seeds can be determined, and a small amount of seeds can be replenished into the adjustment chamber 12-b depending on the situation. Also, if there is more leakage than in the seed storage chamber 12-a, excess seeds are removed.

Reference numeral 13 indicates a seed holding plate, which is fixed to the lower side of both side guide frames 6, 6 via bolts 14', and its upper surface is in sliding contact with the lower surface of the seeding plate 4. Since they have approximately the same length as the guide frames 6, 6, when a seed enters the hole 5 and moves the guide frame 6 left and right as described above, the entered seed is initially supported by the seed holding plate 13, but
When the guide frame 6 advances further, the seed holding plate 13 releases its support and falls.

On the other hand, the lower machine frame 2 has a large number of rollers 14 in the horizontal direction.
is rotatably provided, and a seedling container advancement stop plate 15 is provided at a location half a pitch away from the five rows of holes of the seeding plate 4 and the pot.
is fixed between the lower machine frames 2 and 2. Therefore, when a seedling growing container such as a paper pot A filled with soil and set at a seeding depth is placed on the base plate 16 and transferred over the rollers 14, the front wall of the paper pot A reaches the stop plate 15 and stops.
Each pot comes to be located at the bottom of the holes 5, 5.... At this time, if the seed guide plate 6 is moved, the holes 5,
5... All the seeds enter the pot, and when the seed press plate 13 is released, they fall accurately into the pot. Therefore, all the operator has to do is pull out the paper pot, making seeding work extremely easy.

As described above, the present invention is capable of filling seeds while monitoring the seeding board, and since both the seeding board filled with seeds and the seedling growing container below are stationary and the seeds are dropped, the seeds can be filled like a seeding drum. There is no rotational inertia and the seeds can be sown accurately.
