Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer sowing machine configured to sow seeds in a field while performing a fertilizing operation.

[0002]

2. Description of the Related Art As disclosed in Japanese Patent Application Laid-Open No. 60-192505, there is a fertilizer sowing machine configured to sow seeds in a field while performing a fertilizing operation. This fertilizer sowing machine drives a fertilizer feeding part of a fertilizer and a seed feeding part of a seeding device while running a traveling vehicle body, so that the seed is streaked in a field and a streak is formed near a side of a seeding position in a field. It is configured to simultaneously perform fertilization and sowing for multiple rows. Since this fertilizer-seeding machine is configured to be able to simultaneously perform fertilization and sowing for a plurality of rows, the working travel distance of the traveling vehicle body in the field is smaller than that of a fertilizer-seeding machine that performs fertilization and sowing for a single row. The work efficiency of the fertilizer sowing work is improved.

[0003]

However, depending on the size of the field, the fertilizer-seeding operation may not always be performed with the number of rows provided in the fertilizer-seeding machine, so that fertilization and sowing may not be performed on the entire field. Fertilization and sowing of some of the rows provided by the fertilizer sowing machine must be stopped to perform the sowing operation. When the fertilization and sowing of some of the plurality of strips are respectively stopped, the fertilization of the strip corresponding to the some of the strips is stopped in a state where the operation of stopping the sowing of the some of the strips is performed. When the fertilizer sowing work is performed by running the machine without performing the operation, a part where the seeding is not performed in a fertilized state occurs in the field, and the body is moved to perform the seeding work later in this part. The seeding position performed later with respect to the fertilization position of the fertilization performed earlier when performing the sowing work varies, such as the time when the fertilizer starts to work on this seeded seed, the fertilizing effect on the seed becomes inappropriate and from the seed In some cases, the growth of grown crops becomes poor, and stable crops cannot be obtained.

[0004]

The present invention takes the following technical means to solve the above-mentioned problems. That is, in the fertilizer sowing machine 2 in which the fertilizing apparatus 1 and the sowing apparatus 4 are operated while the machine body is running, the fertilizing and sowing can be performed simultaneously in the form of a streak in a field, the sowing apparatus 4 includes a plurality of sowing units 42. The fertilizer applicator 1 is configured to perform fertilization at a field position corresponding to the seeding position of the field of the sowing units 42 by the plurality of fertilizing units 82. Of the plurality of sowing units 42 of the sowing device 4,
42 in conjunction with the suspension of the sowing operation
Fertilizers 82, 82 of the fertilizer apparatus 1 corresponding to
The fertilizer sowing machine is characterized in that the fertilizer application work is stopped.

[0005]

The above-mentioned fertilizer sowing machine operates a fertilizer and a sowing device while running the machine body, thereby performing fertilizing and sowing in a plurality of lines in a field in a field. This fertilizer sowing machine stops the sowing work of a part of the plurality of sowing sections of the sowing apparatus that performs sowing of a plurality of rows, and the fertilizing section of the fertilizing apparatus of the fertilizing apparatus corresponding to the stopped sowing section. Work is stopped.

[0006]

Accordingly, the fertilizing operation of the fertilizing unit of the fertilizing device corresponding to the stopped sowing unit is stopped by stopping the sowing operation of a part of the plurality of sowing units of the sowing device. Therefore, it is possible to always perform fertilization at an appropriate position with respect to the seeding position of the field when the fertilization operation is performed simultaneously with the seeding operation in the field without erroneously sowing the seed in the field.
