Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention involves cutting and planting seedlings one by one using a seedling planting mechanism that operates vertically circulating from the lower end of pine-shaped seedlings placed on a seedling stand. The present invention relates to a rice transplanter configured as described above.

[Conventional technology]

Considering rice planting work using a rice transplanter with the above structure, conventionally, when planting seedlings in a fixed area of a rice field, setting the amount of seedlings to be removed by the planting claw when using a predetermined number of pine-shaped seedlings. Alternatively, settings such as planting intervals are determined based on the experience and intuition of the operator.

[Problem to be solved by the invention]

However, in the rice transplanter with the above structure, the sliding properties of the pine-shaped seedlings placed on the seedling stand depend on the properties of the seedling soil.
Even if the same feeding force is applied to the seedlings during work, the feeding force will vary depending on various conditions such as root tension, moisture content, and humidity and dryness caused by the weather.
This causes a difference in the amount of movement of the seedlings, resulting in a difference in the planting area for the unit number of pine-like seedlings, making it difficult to use the desired number of pine-like seedlings for a fixed area of rice field. , improvement is desired.

These inconveniences can be alleviated to some extent depending on the experience and intuition of the operator, but even experienced workers cannot set the amount of seedlings to be taken and the seedling spacing to the optimum conditions at the beginning of work. It is difficult to do this, and it is even more difficult when an inexperienced person performs the work, leading to an excess or shortage of pine-like seedlings.

An object of the present invention is to rationally construct a rice transplanter capable of planting seedlings in a rice field of a predetermined area by using a desired number of pine-shaped seedlings in just the right amount and quantity.

[Means for Solving the Problems] As described at the beginning, the feature of the present invention is that the seedlings are cut out and planted one by one from the pine-shaped seedlings on the seedling stand using a seedling planting mechanism that operates in vertical circulation. The rice transplanter is equipped with a counting mechanism for counting the number of times the seedling planting mechanism is operated, and a sensor for detecting the number of pine-shaped seedlings used on the seedling stand, and the rice transplanter is equipped with a sensor for detecting the number of pine-shaped seedlings used, and the distance traveled by the machine is and a setting device for inputting in advance the amount of pine-like seedlings to be consumed, and a setting device for determining whether the consumption status of pine-like seedlings during seedling planting is as desired based on signals from these devices. The function and effect of the present invention are as follows.

[Effect]

According to the above feature, when planting seedlings, the number of pine-shaped seedlings W to be consumed is input into the setting device 18, and the amount of seedlings taken by the seedling planting mechanism A is set appropriately. By starting the work,
During this work, the number of times the seedling planting mechanism A operates within a unit time is counted by a counting mechanism 11, the amount of pine-shaped seedlings W consumed within this unit time is detected by a sensor 12, and the distance traveled by the machine is is measured by the sensor 16, the display device 1
9, the current consumption status of pine-shaped seedlings W is displayed as desired or not, and the operator can control the seedling planting mechanism based on the display contents of this display device 19. The amount of seedlings A can be adjusted to an appropriate value.

In other words, in this invention, after starting work,
By comparing the consumption status of pine-shaped seedlings W during this work with preset conditions, it is possible to avoid the difficult work of setting the optimum amount of seedlings to be taken by the seedling planting mechanism A at the start of work, and to improve the experience. Even those with limited experience can set the appropriate amount of seedlings to be harvested.

〔Effect of the invention〕

Therefore, a rice transplanter has been rationally constructed that can carry out seedling planting work using the desired number of pine-like seedlings in just the right quantity and quantity in a rice field of a fixed area.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 1, a transmission case 2 is connected to the rear of a passenger traveling vehicle (not shown) so as to be able to rise and fall and is driven by a drive shaft 1, and a transmission case 2 is driven by a crankshaft 3 of the transmission case 2. a plurality of planting arms 4..., planting claws 5 attached to the planting arms 4,
Seedling removal amount adjustment knob 6, which can adjust the amount of seedlings taken by changing the operating locus of the planting claw 5 by rotating the operation, a sliding rail 7 disposed on the upper part of the transmission case 2, a sliding rail A star foil 9 sends the pine-shaped seedlings W placed on the forward-inclined seedling tray 8 slidably supported by the seedling tray 7 downward at each stalk end of the seedling tray.
..., a plurality of floats 10 connected below the transmission case 2 via a link mechanism, etc. constitute a multi-row seedling planting device.

And these crankshaft 3, planting arm 4,
The planting claws 5 are collectively referred to as a seedling planting mechanism A.

As shown in the figure, the planting arm 4 is configured to plant one seedling by one revolution of the crankshaft 3, and a counting mechanism 11 is attached to the crankshaft 3.
A foil sensor 12 is attached to the seedling table 8 to rotate as the seedlings move.

Further, as shown in FIG. 2, a sensor 15 is attached to the seedling removal amount adjustment knob 6 to detect the amount of seedling removal from the amount of operation thereof, and a sensor 15 is attached to the traveling wheel (not shown) to detect the amount of seedling removal from the number of rotations of the knob 6. The control device 17 is equipped with a sensor 16 that detects the distance traveled by the computer, and is equipped with a control device 17 to which signals from the counting mechanism 11 and the sensors 12, 15, and 16 are input.
is configured to receive signals from a setting device 18 into which a predetermined number of pine-shaped seedlings W, a slip rate of the running wheels, etc. A display device 19 is provided to output the consumption status of the pine-like seedlings W calculated in step 17.

The display device 19 is equipped with a lamp so as to display "normal" if the consumption status of the pine-shaped seedlings W is as desired, "high" if the consumption is large, and "small" if the consumption is small. A predetermined number of pine-like seedlings W can be planted in the rice field by the operator operating the seedling harvesting amount adjustment knob 6 based on this display.

[Another example]

In addition, when adjusting the consumption amount of pine-shaped seedlings W based on the display contents of the display device 19 in this way,
In addition to the above-mentioned operations, the seedling planting interval can be adjusted, and the seedling removal amount adjustment knob 6 can also be configured to adjust the seedling planting interval.
Instead of adjusting manually, it is also possible to use mechanical driving force by driving an actuator such as a motor.

Further, the present invention may be applied to a walking type rice transplanter instead of a riding type rice transplanter.
