Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is directed to a ridge for cutting and removing weeds on a ridge from a paddy field in a growing rice seedling on which the riding rice transplanter runs by fixing and pulling the rear rice seedling planting device to a lifting and lowering device of the riding rice transplanter. The present invention relates to a riding mowing device.
[0002]
[Prior art]
Conventionally, as a lawn mower for paddy fields, a backpacking type and a shoulder mower have been generally used, but in recent years, the spread of a two-sided self-propelled ridge mower that cuts a flat surface and a slope simultaneously has been remarkable. However, since all of them run on narrow ridges, traveling is extremely unstable and dangerous, so there is no proposal of an automatic riding type.There is no self-propelled fly mower or a mowing device for an agricultural tractor. At present, it is limited to the knowledge of setting and towing and manually operating the steering wheel three-dimensionally.
[0003]
[Problems to be solved by the invention]
When cutting the slope with a conventional shoulder-type mower, the cutting edge rotates at high speed, so if it comes into contact with the water surface of the paddy field, water resistance will cause the front-rear and left-right balance to be lost unintentionally, making it impossible to control and growing. It is said that there are many troubles such as cutting down rice seedlings, which may be dangerous, and that the health of the engine is harmed by the vibration of the engine.
[0004]
The conventional two-sided self-propelled fly mower is manually operated by a steering wheel, weighs 50 to 60 kg, has a problem in stability when running on a levee, and has a problem in that the handle is gripped. If there is a stopcock or rice pile of a culvert on the ridge, it is forced to enter the field or to detour or lift the main body, Significant labor is inevitable.
[0005]
A clipper-type cutting blade dedicated to a slope is lightweight, but requires manual labor, so it is hard to say that it is a comfortable operation to cut down two to three times a year.
[0006]
The current rice and wheat production processes are now possible to be used in all agricultural work, such as plowing, fertilizer application, scraping, sowing and planting, harvesting, straw processing, etc. It is still the old state, and if the riding rice transplanter can operate and work 240 hours a day for 8 hours a day with a working capacity of 30a or more and can plant 240a, the average cultivated cultivated land in Japan is 1.2 million yen to 250 million units. This is an issue from the viewpoint that a rice paddy machine costing as much as ten thousand yen is neglected for use only once a year.
[0007]
The present invention relates to a planting section of a riding rice transplanter conventionally used for a rice transplanter, which is connected to the present invention device by connecting it to a rice transplanter.The riding rice transplanter travels between rice seedlings in a field along a ridge. Another object of the present invention is to provide a device for cutting flat and slope weeds and the like while automatically controlling the cutting height of ridges from within a field.
[0008]
[Means for Solving the Problems]
The present invention removes the conventionally connected planting device of the riding rice transplanter A and connects and pulls the mowing device for ridges. L-shaped slide arm 3 having a flat cutting blade 5 and a slope cutting blade 8 at its tip in a frame of a long frame 1 made of U-shaped steel.

[0009]
The slide arm 3 is connected to a hydraulic cylinder 15 which operates laterally by hydraulic pressure from a hydraulic joint 22, and the flat cutting blade 5 is directly connected to the vertical axis of the flat motor 4, and detects the height of the plant to position the blade surface. The sensor switch 10 moves the electromagnetic sensor 11 with a manual switch that activates a hydraulic cylinder 12 that raises and lowers the lifting link B of the riding rice transplanter A. Connect,
[0010]
Slope cutting blade 8, the long frame 1 side downward plane cutting blade 5, the inclined frame member 6 inclined angle adjustably inclined fixed, mounted directly on the slope motor 7, the slope inclination The sensing switch of the slope sensor 13 that senses the height of the plant is connected to the electromagnetic hydraulic valve 14 with manual switching of the rice transplanter A that operates the hydraulic cylinder 15,
[0011]
The field where rice seedlings are growing is pulled by the riding rice transplanter A running along the ridge, and the hydraulic pump of the riding rice transplanter A automatically activates both the flat surface and the slope by a sensor according to the mowing height. It is characterized in that levee grass is cut off from the field while adjusting the position of the blade surface.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention relates to a conventional weeding rice transplanter A, which is connected to and fixed to a lifting link B at the rear of the paddy rice transplanter A, enters a field where rice seedlings are growing, runs along a ridge, and weeds on a flat surface and a slope of a ridge. From the field.
[0013]
The sliding roller 21 of the slide arm 3 connected to the hydraulic cylinder 15 which operates laterally by hydraulic pressure from the hydraulic joint 22 is rolled into the frame of the long frame 1 which is connected and fixed to the lifting link B by the fixing plate 2. At the very least, the plane cutting blade 5 installed at the tip is directly connected to the vertical axis of the plane motor 4, and a plane sensor 9 for detecting the vertical position of the blade surface is arranged at the upper part. The lifting and lowering link B of the rice transplanter A is connected to the electromagnetic hydraulic valve 11 of the hydraulic cylinder 12 for lifting and lowering, and is directly connected to the slope motor 6 of the tilting frame body 6 which is mounted close to the flat cutting blade 5 and whose tilt angle can be adjusted. The sensing switch of the slope sensor 13 for sensing the inclination height of the sloped cutting blade 8 is connected to the electromagnetic hydraulic valve 14 of the riding rice transplanter A that operates the hydraulic cylinder 15, and the hydraulic pump of the riding rice transplanter A is connected. For the operation of 18 Ri is obtained by said plane, while automatically adjusting the position of the blade surface by the sensor in response to the slope both mowing height, to make a payment cutting the ridges grass from the field.
[0014]
It does not run on unstable ridges as in the past, so there is no danger of falling due to the unstable running of the aircraft and avoids obstacles like a self-propelled fly mower No labor is required to do so.
[0015]
At the start of the ridge weeding operation, the riding rice transplanter according to the present invention is stepped in while growing rice seedlings. First, the electromagnetic hydraulic valves 11 and 14 are switched to manual, and the expansion and contraction of the hydraulic cylinders 12 and 15 are manually performed by hydraulic pressure. By operating, the cutting height is set and fixed at any desired point on both the plane and the slope.
[0016]
That is, the slide arm 3 is protruded from the long frame 1 by the hydraulic cylinder 15 by manually operating the electromagnetic hydraulic valve 14, and the plane cutting blade 5 and the slope cutting blade 8 are brought into contact with the upper surface of the ridge and the field side slope. According to the required plant height, the top end of the spring whose base end is fixed to the slide arm 3 is selected and replaced by selecting one of the spring holes, thereby determining the vertical position of the lower end of the sensor to obtain the desired position. Set to height.
[0017]
Next, when the mowing operation work progress is started , the electromagnetic hydraulic valves 11 and 14 are immediately switched to the automatic side while running between the rice plants along the ridge, and the flat sensor 9 and the slope sensor 13 are operated by the automatic operation. The cutting height of both the flat surface and the slope is automatically controlled, and the weeds on the flat surface and the slope can be automatically trimmed to a desired height .
[0018]
Sensing switch 10 of the planar sensor 9, it operates the solenoid hydraulic valve 11 Then, the hydraulic cylinder 12 is driven, by lifting the lifting link B, up and down by a flat cutting blade 5 correspond to the desired plant height, also, Law The slope cutting blade 8 directly connected to the slope motor 7 of the inclined frame body 6 adjusted to the slope angle of the surface is a sensing switch for sensing the slope cutting height by the slope sensor 13, and is provided via the electromagnetic hydraulic valve 14. By operating the hydraulic cylinder 15, it slides with the slide arm 3 and automatically cuts the flat and slope weeds while automatically adjusting to the cutting height.
[0019]
In other words, the automatic adjustment of the mowing height by the sensor enables easy operation without damaging the rice plant by only hydraulic operation from the driver's seat, and automatically and simultaneously cuts flat and slope weeds extremely efficiently. Therefore, the driver of the riding rice transplanter traveling in the field only cares so as not to damage the growing rice plant and does not require any special skills or skills.
[0020]
When running on public roads or encountering obstacles on ridges, culvert stopcocks, etc., by manually operating the electromagnetic hydraulic valve 14, the slide arm 3 is retracted into the long frame 1 to remove obstacles. It can be avoided and does not violate the vehicle width restrictions stipulated in the Road Traffic Law.
[0021]
The reciprocating motion mechanism of the slide arm 3 to the left and right is not limited to the hydraulic cylinder of the present invention, but may be a motor and a chain motion mechanism. If a smaller mowing grass is desired, a combination of a cylinder and a moving pulley may be used. Alternatively, an engine or a hydraulic motor may be used instead of the motor as a power source of the mowing blade, and the output shaft (PTO) of the rice transplanter body may be used as the power source.
[0022]
Further, the plane cutting blade and the slope cutting blade are not limited to the circular four blades of the present invention, and may be any type such as a plate blade, a circular saw blade, and a clipper-type blade. In the present invention, the height sensor is provided with a mechanical electric circuit conversion sensor, but may be replaced with an optical sensor, a radar sensor, a sound wave, or the like that can control an arbitrary distance.
[0023]
In the present invention, this device is connected and mounted on the rear part of the riding rice transplanter. However, like the rice transplanter, the wheel width is narrow, it does not step on rice plants, it is a lightweight body that can run on soft ground, and it has a lifting device Then, it can be applied to agricultural small tractors and the like.
[0024]
【The invention's effect】
According to the present invention, weeds are connected and fixed to a lifting link B at the rear of a riding rice transplanter A, get into a field where rice seedlings are growing, and run along the ridge while cutting weeds on the flat surface and slopes of the ridgeway from within the field. By automatically adjusting the mowing height using sensors, weeds grow flat and sloped weeds while automatically adjusting to the mowing height. It has the effect of being able to work easily without damaging it, and has the effect of being able to mow flat and slope weeds very safely and efficiently at the same time. The driver of a rice transplanter traveling in a field can hurt a growing rice plant. It does not require special skills or skills, and does not run on unstable ridges as in the past. There is no danger of falling due to unstable running, and There is also an effect of equal effort is also unnecessary for.
