Description

[Detailed description of the invention] The present invention is a rice transplanter equipped with a seedling stand that moves back and forth from side to side and a planting section with a planting claw for taking out one seedling from the seedling stand. Regarding the seedling usage amount detection device that detects the amount of vertical feeding of pine seedlings that are slid down by a vertical feeding mechanism that includes a vertical feeding amount sensor, a vertical feeding amount sensor that detects the amount of pine seedling usage on a seedling platform. and a calculation unit that is operated by a planting sensor that detects a planting operation to calculate the amount of pine seedlings used in the planting unit,
This device is configured to display the amount of pine seedlings used that is output from the calculation unit on a display, which eliminates the need to adjust the number of pine seedlings used in the field immediately before the end of planting, and eliminates the need to adjust the number of pine seedlings used in the field just before the end of planting, which is the conventional method. It also eliminates the need to adjust planting conditions by changing the amount of pine seedlings per plant, and prevents a decline in harvest efficiency due to uneven planting density. The amount of seedlings can be changed at an early stage, the planting density can be maintained almost uniformly throughout the field, and inconveniences such as a shortage or surplus of pine seedlings can be prevented, and rice planting can be carried out efficiently and economically. The present invention aims to provide a device for detecting the amount of seedlings used in a rice transplanter.

The present invention is constructed as described above, and while it travels at a substantially constant speed, the pine seedlings 34 on the seedling platform 18 are taken out at a substantially constant speed by the planting claws 19 and are successively arranged at equal intervals. When the planting clutch lever 28 is engaged, the planting section 16 is driven, and at the same time, the planting operation switch 46 is turned on, and the pine seedlings 34 slide down on the upper surface of the seedling stand 18. The counters 47 to 52 are operated by the output of the Hall element 40 via the NAND circuits 53 to 58, and the usage amount of the pine seedlings 34 in the planting part 16 is sent to the calculation part 64. The number of pine seedlings 34 used in the planting section 16 is then continuously displayed on the display 62, and based on the consumption status of the pine seedlings 34, the speed change between plants and the planting claw 1 are performed.
The rice planting work is carried out by adjusting the amount of seedlings taken in step 9 and so on, so that the planting density in the field is uniform.

For example, when rice transplanting is carried out by moving a rice transplanter back and forth in the field, the number of times the rice transplanter will go back and forth in the field where the rice transplanting work will be performed should be confirmed in advance based on experience, such as the previous year's results, so that the amount of pine that is needed for the entire field can be confirmed. The standard number of pine seedlings required for one round trip is calculated based on the number of seedlings and the number of round trips. Based on the amount of seedlings used by the planting section 16 consumed in one round trip operation converted into the number of pine seedlings and displayed on the display 62, the reference number of pine seedlings calculated in advance and the number of pine seedlings displayed are calculated. The operator compares the number of pine trees actually used to determine whether the amount of seedlings consumed is appropriate, and when the amount of seedlings consumed is large or small, change speed between plants and plant. By performing well-known operations such as adjusting the amount of seedlings taken by the attached claw 19, the amount of seedlings consumed is maintained at an appropriate level.

As is clear from the above embodiments, the present invention includes a vertical feed amount sensor 37 that detects the amount of pine seedlings used on the seedling platform 18, and a planting sensor 46 that detects the planting operation.
The pine seedlings 34 in the planting section 16 are
It is equipped with a calculation unit 64 that calculates the usage amount, and is configured to display the usage amount of pine seedlings 34 outputted from the calculation unit 64 on a display 62, and shows the number of pine seedlings 34 used for the field immediately before the end of planting. It is possible to eliminate the adjustment of the planting condition by changing the spacing between plants and the amount of seedlings per plant, which is a conventional method, just before the end of planting, and it is possible to prevent a decrease in harvest efficiency due to uneven planting density. It is possible to continuously calculate the amount of pine seedlings 34 used during the work and change the spacing between plants and the amount of seedlings per plant at an early stage, making it possible to obtain a substantially uniform planting density throughout the field, and also to increase the number of pine seedlings 34. This has remarkable effects such as being able to prevent inconveniences such as shortages or surpluses from occurring, allowing rice planting to be done efficiently and economically, and being very practical.
