Abstract

PROBLEM TO BE SOLVED: To accurately calculate the real number of planted seedlings during the planting operation with a rice transplanter and effectively inform an operator of the result. SOLUTION: A rice transplanter capable of detecting the number of transplanted seedlings per unit area is provided with a rotational number pick-up device 2 positioned near a rear wheel 1 to detect the rotational number of the rear wheel and the traveling speed of the machine body, a rotational number pick-up device 4 for an engine 3 positioned near the engine 3 and a rotational number pick-up device 6 for a planting arm 5 placed near the planting arm 5. Each of rotational number pick-up devices 2, 4, 6 is composed of a rotor-side magnet and a stationary solenoid pick-up device. The real number of planted seedlings calculated by a controller CPU based on the detection results in the rotational number pick-up devices 2, 4, 6 is displayed on a display 9 positioned near the driver's seat 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting stock number calculation and display device for a rice transplanter capable of calculating and displaying to an operator the number of actual planting stock during planting work.

[0002]

2. Description of the Related Art Conventionally, in a rice transplanter that detects the number of planted seedlings per fixed area, a vehicle speed sensor that detects the vehicle speed of the aircraft and a planted arm rotation sensor that detects the rotation speed of the planted arm are detected. The one configured to calculate the number of planted plants based on the above is known as seen in Japanese Patent Laid-Open No. 242606/1990.

[0003]

However, as described above, the detection of the number of rotations only by the vehicle speed sensor and the planting arm rotation sensor is another factor in calculating the accurate number of planting stocks. In addition, the operator cannot know the calculated actual number of planted plants, and cannot confirm the exact number of planted plants.

[0004]

SUMMARY OF THE INVENTION The present invention solves such a problem and makes it possible to accurately calculate the actual number of planted plants during planting work and display them effectively for the operator. In a rice transplanter designed to detect the number of planted seedlings per fixed area, the rear wheel rotation speed pickup device provided in the vicinity of the rear wheel to detect the traveling speed of the aircraft and the engine rotation speed are set. An engine rotation speed pickup device provided near the engine for detecting the rotation speed, and a planting arm rotation speed pickup device provided near the planting arm for detecting the rotation speed of the planting arm. Each of the rotation speed pickup devices includes a rotation side magnet and a fixed side electromagnetic pickup device, and a controller based on detection of each rotation speed pickup device. The actual number of shares the with was calculated planted that by the judgment,
The display is provided on a portion near the driver's seat.

1 is a side view of a rice transplanter for riding, which includes front wheels 18, rear wheels 1, engine 3, steering wheel 1.
1. In the rear of the machine A equipped with the driver's seat 10 and the like, each float 12, each planting case 13, each planting rotor 5a having both planting arms 5, the planting platform 14 equipped with the planting The part B is connected through the link mechanism 15 and is constructed in the same manner as the conventional structure.

In order to detect the number of revolutions of the engine 3 including a magnet 7 provided on the rotating side and an electromagnetic pickup device 8 on the fixed side provided close to the magnet 7 in the vicinity of the engine 3. The rotation speed pickup device 4 is attached, and in the vicinity of the rear wheel 1, the magnet 7 provided on the rear wheel support disk 1a and the magnet 7 are provided.
A rotation speed pickup device 2 for detecting the traveling speed of a vehicle body including a fixed-side electromagnetic pickup device 8 provided on the outer surface side of the rear case 16 in the vicinity of the planting arm 5. The part of the planting arm includes a magnet 7 provided on the side surface of the rotating planting rotor 5a, and a fixed electromagnetic pickup device 8 provided on the outer surface of the planting case 13 close to the magnet 7. The rotational speed pick device 6 for detecting the rotational speed of the motor 5 is attached and configured, but the magnet 7 rotates and the electromagnetic pickup device 8 detects the rotational speed while picking up a pulse.

Controller CPU equipped on the machine A
Is configured so that the number of actual planted plants, which is the number of plants per fixed area of planted seedlings, can be determined based on the detection of each of the rotation speed pickup devices 2, 4, and 6.

Further, the panel portion 17 below the handle 11 is provided with a display surface 9a capable of displaying the actual number of planted plants determined by the controller CPU and a plurality of lamps 9b capable of displaying the planting speed. A display unit 9 is provided.

Therefore, since the engine 3, the rear wheel 1 and the planting arm 5 are operating during the planting work, the engine 3 is driven by the respective rotation speed pickup devices 4, 2 and 6.
It is possible to detect the number of rotations of the plant, the traveling speed of the airframe, and the number of rotations of the planting arm 5, respectively. Moreover, the planting speed can be displayed by turning on one of the lamps 9b, and the operating operator can check the display unit 9 to confirm the exact number of planted plants and the planting speed.

[0010]

As described above, according to the present invention, the rear wheel 1, which includes the rotating-side magnet 7 and the fixed-side electromagnetic pickup device 8, the engine 3 and the rotation speed pickup devices 2, 4 for the planting arm 5, respectively. 6, the traveling speed of the airframe and the rotation speeds of the engine 3 and the planting arm 5 can be detected accurately, and the controller C based on accurate detection of the respective rotation speed pickup devices 2, 4, 6 is detected.
The number of planted actual plants can be calculated accurately by the judgment of PU, and the operator of the driver's seat 10 can easily confirm the exact number of planted plants displayed on the display unit 9 during operation, and the electromagnetic pickup device 8 Since the magnet 7 and the magnet 7 can be easily attached to the rear wheel 1, the engine 3 and the vicinity of the planting arm 5, respectively, a feature that can be suitably implemented with a simple structure without additional adjustment after assembling is provided. Have.
