Next, the functions and effects of the present invention will be explained.
For example, when sowing is performed at the same time as fertilizing, the mounting portion 38a of the seeding device 38 is inserted into the fixed hitch 5 and connected and mounted using the connecting pin 39. The support frame 19 and the nozzle mounting base 24 for the fertilizer application device are installed at positions that do not interfere with the installation of the seeding device 38, that is, from the upper and front surfaces of the fixed hitch 5 downward, so the installation of the seeding device 38 is easy. It can be done extremely easily.

Next, the relative position and number of rows for fertilization with respect to the seeding device 38 are adjusted by adjusting the vertical and horizontal mounting positions and number of the groove rods 31. At this time, the vertical position of the groove rod 31, that is, the fertilizing depth, can be adjusted by adjusting the vertical position of the center bracket 27 and the side brackets 28 using the marking scale 28a as a guide, and the horizontal position, that is, the fertilizing interval can be adjusted using the holder 33. It is adjusted by the left and right displacement of. Also, by reducing the number of groove rods 31, the distribution pipe 21
Keep the discharge port closed. When adjusting the position of the groove rod 31 described above, the base of the hose 37 is connected to the distribution pipe 21.
Since they are supported by the support frame 19 via There is no stagnation or stagnation.

Then, while filling the seeding device 38 with seeds,
When the liquid fertilizer tank 9 is filled with liquid fertilizer and work is started, multiple fertilization grooves are cut in the soil by the groove rod 31 as the machine advances, while the liquid fertilizer tank 9
The filled liquid fertilizer is supplied to the distribution pipe 21 by the action of the pump 7, from which it is distributed to the nozzles 32 attached to each groove-making rod 31, and discharged from the tip thereof into the liquid fertilizer groove. Further, the seeds discharged from the seeding device 38 are sown at the above-mentioned fertilization position and at a set interval.

In the above-mentioned furrowing and fertilizing action, the furrowing rod 31 penetrates into the field soil and moves forward, so considerable resistance is applied to the nozzle mounting base 24 that supports it.
Since the nozzle mounting base 24 is mounted below the fixed hitch 5 and is constructed integrally with the machine frame 1, it has sufficient strength and will not be deformed or damaged during work.

When only fertilizing fields, use the seeding device 38.
Alternatively, when fertilizing and cultivating at the same time, the tilling device can be replaced with the seeding device 38 and the tilling device can be fitted onto the fixed hitch 5.
Like 8, it is extremely easy.

In this way, the present invention provides a fixed hitch which is U-shaped in side view with the rear side open in the rear part of a mobile agricultural machine, and a support frame for attaching a hose is horizontally fixed in a long horizontal direction on the upper surface of the fixed hitch. At the same time, both end portions of the support frame are bent downward to form a hanging part, while below the fixed hitch there is a horizontal plate equipped with a plurality of fertilization nozzles arranged on the left and right sides. The support rod is fixed to the nozzle mounting base hanging down from the fixed hitch so that it can be adjusted up and down, and the left and right hanging parts of the support frame and both ends of the support rod are connected and fixed so that the vertical position can be adjusted freely. By providing both a support frame for attaching multiple hoses of the device and a nozzle mount for securing a support rod with multiple fertilization nozzles on the upper and lower surfaces of the stationary hitch, it is possible to attach the stationary hitch to other work equipment. For example, it is now possible to easily attach seeding equipment, tillage equipment, etc., thereby expanding the use of mobile agricultural machinery for complex operations. Since both the left and right ends of the support rod are connected to each other, the structure is simple, yet it has an integrated framework structure that can support even heavy objects in a sturdy and stable state. Moreover, the height of the working machine, the spacing between the strips, etc. can be freely adjusted.
