Description

Sowing system for selective suction and dropping of seeds}

The present invention relates to a seeding system capable of selectively inhaling and discharging seeds. More specifically, it is a technical field related to a seed sowing system capable of simultaneously inhaling a large amount of seeds by expanding the suction surface area of seeds and selectively discharging the inhaled large amount of seeds to a predetermined location.

Sowing refers to planting seeds used for propagation of crops, and generally means to sow seeds.

Recently, weekend farms in the form of cultivating vegetable gardens using fallow land on the outskirts of large cities and small and medium-sized cities have become popular. The number of urban farmers cultivating vegetable gardens in cities has increased rapidly.

According to the Ministry of Agriculture, Food and Rural Affairs, the number of urban farmers in Korea increased from 153,000 in 2010 to 880,000 in 2013, a 5.8-fold increase in three years.

Although interest in urban agriculture has increased, it is not difficult to find failures due to lack of preparation and agricultural knowledge in advance. In general, depending on the method of planting vegetables, it can be divided into cases of sowing seeds or purchasing seedlings and planting them. Especially in the case of sowing seeds, there is a high possibility of failure because the sowing method differs depending on the type and size of seeds. .

Therefore, there is a need for a technology that allows even those who are new to farming to sow easily, simply, and efficiently, and there are various patent documents for this.

As an example of a related prior patent document, there is a “seedling machine for raising seedlings (Publication No. 10-2014-0142482, hereinafter referred to as Patent Document 1)”.

In the case of the invention according to Patent Document 1, it relates to a seeding machine, and in particular, to provide a seeding machine for raising seedlings capable of efficiently, efficiently and uniformly sowing seeds of various crops in a nursery box.

To this end, in the invention of Patent Document 1, a space for containing and spreading seeds is formed inside, a plurality of seed inlets are arranged in a certain pattern on the bottom surface, and guide rails are formed on both sides of the basket, and the basket A spread that spreads the seeds contained in the basket while sliding along the guide rail, a base formed with a plurality of seed outlets that communicate with the seed inlet of the basket, and a base that is slidably mounted between the basket and the base and communicates with the seed inlet and seed outlet. Disclosed is a seeding machine for raising seedlings including a slider having a plurality of seed passage holes and a spring providing elastic force so that the seed passage holes of the slider are displaced from the seed inlet and the seed outlet.

As an example of another patent document, “portable seeder (Publication No. 10-2019-0129568, hereinafter referred to as Patent Document 2)” exists.

In the case of the invention according to Patent Document 2, a seed mounting portion formed with a plurality of holes through which seeds can pass and forming a space for holding seeds, and a movement passage for forming a movement passage for seeds corresponding to the holes formed on the bottom of the seed mounting portion, respectively. a seed discharging unit provided at the end of the moving passage and discharging seeds; a passage opening/closing unit positioned between the seed mounting unit and the moving passage to transport seeds contained in the seed mounting unit to the moving passage; and a passage opening and closing unit according to a user's operation. It is made including a seeding control unit for controlling the position of.

As an example of another patent document, there is a “portable direct seed sowing machine (Registration No. 10-2026779, hereinafter referred to as Patent Document 3)”.

In the case of the invention according to Patent Document 3, the seeds accommodated in the seed accommodating space are naturally introduced into the seed supply port by the slope of the hopper surface, and are placed in a state where they are collected in the required amount on the seeding door of the spout. If the hole size of the seeding depth adjusting means is selected as desired, the seeding depth adjusting means can be made constant because the seeding depth adjusting means is caught on the surface of the hopper and does not go up any more. When you start to press the push switch, the piston starts to come down while overcoming the spring's elastic reaction force, and the push part of the piston pushes the seeding door down. At this time, the seeds are naturally gathered in the seed convergence space formed concavely above the center of the push unit, so that the seeds are prevented from being damaged by being pressed between the piston and the seeding door. When the push switch is further pressed, the plurality of segments constituting the seeding door come down and open by the pushing force of the pusher, and as a result, the seeds are discharged out of the spout and sowing is performed.

As an example of another patent document, there is a “seeder (Publication No. 10-2020-0079087, hereinafter referred to as Patent Document 4)”.

In the case of the invention according to Patent Document 4, a seeding pipe in the form of a pipe is provided, but the upper side of the seeding pipe forms a funnel-shaped inlet, a fixing table is provided in close contact with the side of the seeding pipe and is fixed, and a handle is placed on the upper side of the fixing table.
