This invention is configured to control the position of the agricultural working machine 4 with respect to the mud surface based on the change in the attitude of the ground leveling tool 6 attached to the riding vehicle body 1 side, so that the position control of the agricultural working machine with respect to the mud surface is performed. It is possible to maintain accuracy regardless of the high working speed, and it is possible to hold the agricultural working machine in a predetermined working position even at the high working speed, so that good and efficient agricultural work can be performed. In addition, since no ground leveling tool is provided on the agricultural machine 4 side, the agricultural machine 4 side becomes lighter and requires less driving force to control. Therefore, the drive means can be small and lightweight, and the entire machine body has a lightweight structure. It can be done. Furthermore, since no soil leveling tool is provided on the side of the agricultural working machine 4, the agricultural working machine 4 is not affected by the bad influence from the muddy surface, and proper agricultural work can be carried out.

An embodiment of the present invention will be described in detail based on the drawings. Reference numeral 1 is a passenger-type traveling vehicle body, which includes a fuselage 7, an engine 8, a steering handle 9, a transmission case 10,
Consists of a cockpit 11, driving front wheels 12, 12 for steering, and rear driving wheels 5, 5, etc. provided on chain cases 13, 13 extending rearward and downward from both left and right sides of the transmission case 10. has been done. Reference numeral 4 denotes a seeding device, which is a type of agricultural working machine, and is attached to the riding vehicle body 1 by a link mechanism 3 so as to be vertically movable, and five seeding devices 15 are arranged side by side in the left and right direction on a frame 14. It is composed of The seed sowing machine 15 is driven by a shaft 19 that rotates by the rolling of a seed rice tank 17, ground rolling wheels 18, 18, and a trencher 16 that forms a seed seeding machine on the mud surface, and is a feeder that feeds out a fixed amount of rice seeds in the seed rice tank 17. It is composed of a device 20, a guide 21 that guides the seed rice fed out by the feeding device 20 into the yard formed by the trencher 16, and a backfilling plate 22 that backfills the groove in which the seeds are sown. Reference numeral 6 denotes a ground leveling tool provided between the rear wheels 5, 5 and the seeding device 4, and is rotatably pivoted around a rolling shaft 25 on a U-shaped frame 24 rotatably supported on a shaft 23. supported. Numerals 26 and 26 are bullets, which are provided to prevent the ground leveling tool 6 from rolling more than necessary. 27 is a continuous pestle extending upward from the ground leveling tool 6, and its upper part is connected to a shaft 28 provided between the left and right lower links 3a and 3b of the link mechanism 3 via an elongated hole 29. Therefore, when the seeding device 4 is raised by the link mechanism 3 when turning the machine, the ground leveling tool 6 is also raised by the continuous pestle 27. Reference numerals 30 and 31 are detection devices for detecting rolling and vertical movement of the soil leveling tool 6 relative to the seeding machine 4, and are activated by operating pieces 30' and 31' that are integrated with the soil leveling tool 6 and the operating piece 30', respectively. Switch S 1 , S 2
and a switch S 3 operated by actuating piece 31',
It is composed of S 4 . Reference numeral 2 denotes a lifting device, which is composed of left and right hydraulic vertical movement devices 2a and 2b. In addition, 36 is a center marker provided at the center position of the left and right sides of the aircraft body. Next, the operating state of the left and right hydraulic vertical movement devices 2a and 2b will be described based on FIGS. 5 and 6.
For example, when the soil leveling tool 6 is rolled in the A direction due to unevenness of the mud surface, or when the soil leveling tool 6 is rolled in the A direction relative to the seeding device 4 due to the tilt of the tiller, the actuating piece 30' connects the switch S1 , When the actuating piece 31' connects the switch S4 , the solenoids SOLLU and SOLRD are activated, and the valves 32,
33 is switched, pressure oil is supplied to the left hydraulic cylinder 34, and pressure oil in the right hydraulic cylinder 35 is discharged to the tank T, so the left hydraulic vertical movement device 2a moves the lower link 3a upward, The right hydraulic vertical movement device 2b moves the lower link 3b downward.
Therefore, the seeding device 4 is rotated by approximately the same angle as the rolling angle of the ground leveling tool 6 in the A direction, and follows the mud surface. Similarly, when the ground leveling implement 6 is rolled in the opposite direction, the actuating piece 30' connects the switch S2, and the actuating piece 31 ' connects the switch S3 .
Solenoids SOLLU and SOLRU operate, valves 32 and 33 are switched, and left hydraulic cylinder 3
The pressure oil in 4 is discharged to the tank T, and the pressure oil is supplied to the right hydraulic cylinder 35, so the seeding device 4 is rotated by approximately the same angle as the rolling angle of the soil leveling tool 6 in the opposite direction. Follow the surface. In addition, the ground leveling tool 6 pitches (rotates) around the shaft 23 in the mouth direction.
In this case, the switches S 1 and S 3 are connected by the actuating pieces 30' and 31', and the solenoids SOLLU and SOLLU are connected.
SOLRU operates, and the left and right hydraulic cylinders 34, 3
Since pressure oil is supplied into the seeding device 5, the seeding device 4 rises by the pitching angle of the soil leveling tool 6 in the direction A.
Follow the mud surface. When the soil leveling tool 6 pitches in the opposite direction, the seeding device 4 similarly descends by the pitching angle of the soil leveling tool 6 in the opposite direction, and follows the mud surface. That is, when sowing is performed by driving each part of the riding-type seeding work machine configured as in the embodiment, the soil leveling tool 6 levels the mud surface while always following the mud surface, so that the rolling of the soil leveling tool 6 is prevented. In addition, the seeding device 4 can be tilted and moved up and down in accordance with the pitching, so that the seeding device 4 can be maintained at a constant position with respect to the mud surface, regardless of the unevenness of the mud surface or the slope of the plowing platform. Seeding is always carried out at a constant seeding depth. In addition, since no ground leveling tool is provided on the agricultural machine 4 side, the agricultural machine 4 side becomes lighter and requires less driving force to control. Therefore, the drive means can be small and lightweight, and the entire machine body has a lightweight structure. Furthermore, since no soil leveling tool is provided on the side of the agricultural working machine 4, the agricultural working machine 4 is not affected by the bad influence from the mud surface, and proper agricultural work can be carried out. In addition, if the installed rolling wheels 18, 18 are located at the center of the interval 1 between the sowing positions A and A in plan view, that is, at a position 1/2 away from the left and right outermost sowing positions A and A. It is convenient that the ground rolling wheels 18, 18 can be used as conventional line drawing markers. Further, in the above embodiment, an example was shown in which the agricultural working machine was equipped with a seeding device, but other working machines such as a rice transplanting device may be installed.
