Description

Description: TECHNICAL FIELD The present invention relates to a rice transplanter with a fertilizer application device equipped with a fertilizer application device that sprays fertilizer in the vicinity of seedlings planted on a rice field.

[Conventional technology]

During planting work in paddy fields, various fertilizers are used according to the properties of the paddy field and the type of seedlings.The type of fertilizer, the size of fertilizer, the amount of fertilizer applied per unit area, and the spacing between seedlings to be planted are various. Depending on the fertilizer application conditions, the appropriate value of the delivery amount of the fertilizer application per unit time also differs, so it is necessary to change and adjust the delivery amount of the fertilizer application at appropriate times.

In this case, the appropriate value of the delivery amount in the fertilizer application is determined by the operator from the graph showing the relationship between the various fertilization conditions and the appropriate delivery amount described above, and the operator determines that the determined appropriate delivery amount is obtained. The feed rate of the fertilizer application is changed and adjusted.

[Problems to be Solved by the Invention]

Since there are many factors that determine the appropriate feed amount of the fertilizer application, such as the particle size of the fertilizer as described above, the number of graphs for obtaining the above-mentioned appropriate feed amount is also large. Therefore, it is difficult and uncomfortable for an unskilled person to find out the appropriate amount of feeding of the fertilizer application based on various fertilization conditions from the large number of graphs.

It is an object of the present invention to configure a rice transplanter with a fertilizer application so that an appropriate feeding amount of the fertilizer application can be obtained as easily as possible.

[Means for Solving the Problems]

A feature of the present invention is that the rice transplanter with a fertilizer application as described above is configured as follows.

It is equipped with a calculator that has an input section for inputting the particle size of fertilizer and fertilizer application conditions, and a calculating means for calculating the appropriate feed amount of the fertilizer applicator based on the information from the input section, as well as feeding each feed strip of the fertilizer applicator. Adjusting means for automatically changing and adjusting the feeding amount of each feeding strip of the fertilizer application at the same time so that the amount becomes the appropriate feeding amount calculated by the computing unit, and the feeding amount of each feeding strip of the fertilizer application is changed independently. And an adjustable adjuster.

[Action]

With the configuration of the present invention, the operator only needs to input the fertilizer application conditions such as the particle size of the fertilizer and the fertilizer application amount per unit area to the calculator, and the operator can obtain the appropriate feed amount of the fertilizer applicator. This gives the worker 1 out of many graphs.
It is not necessary to perform a troublesome work such as finding one proper feeding amount.

When the proper feeding amount is obtained as described above, the feeding amount of each feeding strip of the fertilizer application device is automatically changed and adjusted at the same time by the adjusting means so that the feeding amount of each feeding strip of the fertilizer application device becomes the appropriate feeding amount. Therefore, it is not necessary for the operator to perform the work of adjusting the feeding amount of each feeding strip of the fertilizer application one by one.

In addition, when the respective feeding amounts are varied and adjusted by the adjusting means at the same time, if the respective feeding amounts vary, it is possible to reduce the variation by independently adjusting the feeding amounts by the adjusting unit. It is also possible to increase or decrease the feeding amount of the particular feeding strip.

〔The invention's effect〕

As described above, it becomes possible to easily obtain the appropriate feeding amount without looking at many graphs, and the feeding amount of each feeding strip of the fertilizer application device is automatically changed and adjusted at the same time based on this appropriate feeding amount. As a result, the workability of adjusting the feeding amount of the fertilizer application device can be improved. Further, since each adjusting amount can be changed and adjusted independently by the adjusting portion, the workability is further improved.
