Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention includes, for example, a conveyor that transports soil selected from raw material soil to a culture soil tank, a chemical tank that contains fertilizers and pesticides necessary for raising seedlings, and This invention relates to a device that continuously supplies a large amount of soil for seeding, which is mixed with soil and chemicals in appropriate proportions from each tank.

``Prior Art'' Conventionally, as shown in Japanese Utility Model Application No. 48-61005, there has been a technique in which sorted soil from a soil sieving machine is sent to a soil tank by a conveyor.

"Problems to be Solved by the Invention" However, in the above-mentioned conventional technology, the soil from the soil tank is directly put into the seedling box, so chemicals such as fertilizers and pesticides can easily be mixed into the soil. For example, by mixing chemicals into the soil before sorting, the labor of stirring can be saved, but there is a lot of wasteful use of chemicals, which is uneconomical. As a result, chemicals were mixed unevenly, and chemicals had to be added to the soil in the seedling nursery box after sowing, making the work extremely troublesome.

Furthermore, as shown in Japanese Utility Model Application Publication No. 47-25302, in the technique of providing a supply passage between a hopper for supplying soil and a seeding table, as shown in Japanese Patent Application Laid-open No. 53-2210, a method for supplying cultivation soil to a seeding table is used. If the hopper and fertilizer or chemical hopper are provided separately, there will be problems with the amount of storage in the hopper and the content of the mixing of the chemicals, etc.It is important to improve work efficiency in supplying soil and supplying fertilizers or chemicals. Another problem was that it was not easy to improve the functionality of the supply means.

In addition, the technology for producing ready-mixed concrete as disclosed in JP-A-49-19561, as well as JP-A-49-19561,
Although there was a technique for mixing different types of rice as in Publication No. 30134, there was no suggestion of a technical idea of mixing and moving soil and fertilizer or chemicals, or a technical idea of moving only the soil.
Since the properties of soil, fertilizers, or chemicals are significantly different from those of concrete or grain (rice), it is difficult to obtain a structure that moves soil, fertilizers, or chemicals, and it is extremely difficult to improve it to a practical level. It was hot.

"Means for Solving the Problems" The present invention provides a soil tank and a chemical tank at the end of the conveyor via a bifurcated damper, and a soil supply hopper for seeding and a chemical input hopper at the starting end of the conveyor. In the seeding soil supply device, which is equipped with a seeding platform for raising and sowing seedlings, a mixing conveyor is provided between each tank and the seeding platform to mix and move the soil and fertilizer or medicine, and The present invention is characterized in that a soil transport conveyor that moves only the soil is provided between the bifurcated damper and the seeding table.

``Function'' Therefore, the conveyor that moves only the soil receives the supply of soil directly from the two-pronged damper, and the soil tank only discharges the soil to be mixed with fertilizer or chemicals. Cultivating soil can be supplied to appropriate locations on the seeding platform, and the supply of cultivated soil, which is required in large quantities during continuous seeding work, can be divided into, for example, bed soil and covering soil, and can be efficiently moved to the seeding platform, and cultivation soil as well as fertilizers or chemicals can be supplied. can be carried out efficiently and functionally.

Further, the lower level meter 4 of the chemical tank 17
5 is activated to warn of a shortage of fertilizers and pesticides in the tank 17, only the first two-pronged damper 14 is operated to communicate the feed end of the third conveyor 12 with the chemical tank 17, and the soil storage chamber 2 Fertilizers and pesticides are put into the chemical input hopper 13 and the fertilizers and pesticides are carried into the chemical tank 17 by the third conveyor 12 via the damper 14. (sorted soil) and fertilizer etc. are mixed in a set ratio by a ribbon mixer 20 to make bed soil, and the horizontal damper 21 is opened and closed to cause the bed soil in the mixer 20 to fall into the hopper 22. soil as the fourth
The soil is carried to the rotary dresser 25 by the fifth conveyor 23, 24, and stored in the finished bed soil tank 26 by the dresser 25.
6 to the soil filling machine 28, and covering soil from the tank 32 to the soil covering machine 30, each part of the seeding table 27 is driven to continuously move the seedling box, so that the seeding work is continuously carried out. It is something to do. In addition,
As mentioned above, the seedling raising box after sowing is mounted on the seedling raising cart, and the seedling raising box is placed in the budding chamber 4 and the first and second greening chambers 5, 6.
The seedlings are raised by moving the seedlings one after another.

"Effects of the Invention" Therefore, in the present invention, since the conveyor that moves only the soil receives the supply of soil directly from the bifurcated damper, the soil tank only needs to release the soil to be mixed with fertilizer or chemicals, It is sufficient if the soil can be released in a fixed amount in cooperation with the tank, so there is no need to release soil in cooperation with the seeding platform, and the soil tank does not need any complicated functions.

In addition, in the case of only using soil, there is no unnecessary process of passing through a soil tank during transportation, which speeds up the work.
