問題点がある。Problems to be solved by conventional techniques and ideas Conventionally, plowing and sowing are performed at the same time, and the soil surface is compacted using, for example,
The one described in Publication No. 48091 is known. The device described in this publication has a seeding machine and a plurality of pressure wheels installed at the rear of a wide tilling device, and with this configuration, the entire grassland is tilled, so the grass is left in the tilled area. There is a problem in that it is crushed into pieces and cannot be used as feed for livestock.

る。Means to solve the problem This idea is to leave part of the grass as feed for livestock, plow the remaining grassland, and sow seeds at the same time, so that the entire pasture can be kept evenly and in good condition as a green space. The purpose is to provide a simple renewal machine, and in particular, it is intended to suppress the evaporation of moisture in the seed bed and maintain the smooth growth of pasture grass.
For this reason, this invention has taken the following technical measures. That is, a plurality of tilling sections are provided at approximately constant intervals in the left and right lateral directions, the left and right sides and the rear of each tilling section are covered with a cover, and the rear of the tilling section is provided with a seed hopper, a feeding section, and a seeding pipe. In a simple pasture renewal machine that is connected to a seeding device, the end of the seeding pipe is extended downward to approach the ground, and behind it is provided a plurality of compression wheels that press the surface of the tilled soil, The pressing device of a simple pasture renewing machine is characterized in that the rolling pressing surface of the pressing wheel is set to a width that fits within the plowing width.

考案の作用、効果 この考案は前記の如く構成されているので、次
のような作用効果を奏する。Functions and Effects of the Device Since this device is configured as described above, it has the following functions and effects.

即ち、耕耘部は左右横方向に一定間隔をあけて

に列状に草を残すことができて家畜の飼料として
利用できる。 That is, a plurality of tilling sections are provided at regular intervals in the left and right lateral directions, and the left and right sides and the rear are covered with covers, so it is not possible to till the entire tillage width and crush the grass like in conventional equipment. Grass does not cause problems such as mulching or burying grass in plowed soil, and the grass can always be left in rows at regular intervals, which can be used as feed for livestock. .

い。 Furthermore, the pressure wheel that presses the seeds released from the lower end of the seeding pipe together with the soil is set to such a width that its rolling pressing surface fits within the plowing width. It can be compacted reliably, and unlike conventional methods, the compaction wheel rides up on the uncultivated area, resulting in insufficient compaction of the plowed area, which results in accelerated evaporation of water from the surface of the plowed soil, which hinders seed germination. There will be no problems such as causing problems.
