no. 1 Embodiment approach

[0088] In the paddy field operation machine related to this embodiment, as shown in FIG. 10 , the rear portion of the central grounded buoy 26 is supported to swing up and down around the horizontal axis core b of the seedling planting device 5 , and the central grounded buoy 26 is equipped with a detection center. The potentiometer 27 of the height of the seedling planting device 5 is used, and the detection value of the potentiometer 27 is input to the control device 28 . Along with the advancement of the body, the grounding buoy 26 at the center is always grounded with the field surface, and by detecting the height of the grounding buoy 26 at the center relative to the seedling planting device 5 according to the detection value of the potentiometer 27, it can be detected from the field surface (the grounding buoy 26 at the center) to the ground. The height of seedling planting device 5.

no. 2 Embodiment approach

[0114] In the above-mentioned embodiments, the tilt angle detection result is preferably set as follows. That is, as shown in Figures 15 to 17, an angle sensor 61 and an angular velocity sensor 62 are equipped, and a horizontally long cylindrical support frame 87 is installed laterally on the paddy field operation device to transmit the transmission box for the operation power derived from the traveling body. 14 is connected to the support frame 87, and the angle sensor 61 and the angular velocity sensor 62 are installed and supported near the swing fulcrum of the support frame 87.

[0115] Specifically, a bracket 82 for mounting sensors is connected and fixed to the upper surface of the transmission case 14 , and the angular velocity sensor 62 and the angle sensor are mounted on the bracket 82 . The bracket 82 is a highly rigid member formed by bending a steel plate into a box shape opened rearward, and its bottom plate portion 82 a is firmly fixed to the upper surface of the...

no. 3 Embodiment approach

[0119] 18 and 19 show a ride-on rice transplanter with a fertilization device as an example of the paddy field work machine according to the present invention. This ride-on rice transplanting mechanism has a specification of 6 planting lanes. At the rear of the four-wheel drive traveling body 3 with front wheels 1 and rear wheels 2, it is equipped with a lifting mechanism of a parallel four-bar linkage structure driven by a hydraulic cylinder 8. The link mechanism 4 and the seedling planting device 5 are freely connected and supported on the lower rear end of the lifting link mechanism 4 around the fulcrum x facing forward and backward, and the fertilization device 6 is mounted on the rear of the traveling body 3 .

[0120] The above-mentioned seedling planting device 5 includes: a seedling placement platform 23 for placing 6 pad-shaped seedlings and moving reciprocatingly and laterally with a certain stroke, and cutting out a seedling amounting to one plant from the lower end ...

Abstract

The present invention provides a swing-control equipment for the task machine, it avoids dilapidation of the task equipment manipulation structure's motivate implement which is supported at the machine body and make the pose of task machine varying at liberty. The swing-control equipment includes: a swing-freely task equipment which is supported at the running machine body(5),a motivate implement which is used to drive the task equipment mentioned(53),slope-measure machines(61,62) that test the right and left slope angle(B) of the running task machine. the operation signal of the mentioned motivate machine(53) is controlled by test result of the mentioned test organ(61,62) and warp of the object's slope angle, make the task machine's right and left slope angle close to the objective angle, therein, contains the load-testing organ which tests the drive load of the mentioned motivate equipment, and protective organ controlling the operation signal of the mentioned motivate equipment and maintaining the mentioned drive load to the objective extent.

Description

technical field [0001] The invention relates to a swing control device used on agricultural machines such as rice transplanters or agricultural tractors. Specifically, it relates to an operating device operating structure of a working vehicle, which is provided with an actuator that is supported on a machine body to freely change the posture of the working device (such as lifting or swinging) to change the posture of the working device, thereby changing the working device The pose relative to the body. Background technique [0002] In a ride-on rice transplanter as an example of a work machine, as shown in Japanese Patent Application Laid-Open No. 2002-84829, an actuator such as an electric motor is provided to support the seedling planting device so that it can swing freely, and to swing and drive the seedling planting device. and a control device that outputs an operating signal to the actuator. [0003] In this way, the seedling planting device is maintained horizontall...
