Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-row planting and seedling planting device connected to a riding machine and is formed in a field at the rear side with a grooving device. The present invention relates to a rice transplanter with a fertilizer application, which is provided with a fertilizer application configured to drop-feed powdery fertilizer sent through a pipeline into a fertilizer groove for each strip. [0002] In this type of rice transplanter with a fertilizer application, the fertilizer stored in the hopper is dropped by a predetermined amount by a feeding mechanism that operates together with the operation of the seedling planting apparatus, and is dropped in this manner. It is generally known that fertilizer is fed to the field through a hose and a groover.However, with such an automatic fertilizer feeder, the fertilizer in the middle of feeding is stagnant for some reason. If the fertilizer is exhausted or the fertilizer is used up, seedlings may be planted without applying fertilizer. In this way, when seedlings are planted in a state where fertilization is not partially performed, in a part of the field during the growth process of seedlings, a group of extremely poorly grown seedlings appears, This will lead to a deterioration in the profitability at harvest. Therefore, in the past, in order to detect the delivery state of the fertilizer, in a rice transplanter with a fertilizer application provided with a fertilizer application configured to drop and supply the granular granular fertilizer sent from the material storage hopper through the pipeline. ,
A detection sensor for detecting a state in which the fertilizer to be delivered from the fertilizer storage hopper cannot be delivered is provided below the fertilizer delivery roll, and an alarm means is provided to notify the driver of the detection result (for example, , Actual Kaisho 5
9-77328). According to the above-mentioned conventional structure, by providing the sensor capable of detecting the state in which the fertilizer cannot be fed out and the alarm means, it is possible to plant the seedling without supplying the fertilizer. What is done is useful in that it can be avoided after detection by the sensor. However, the conventional structure described above has the following problems because it is performed by detecting the falling state of the fertilizer from the feeding roll in determining whether or not the fertilizer is properly delivered. That is, in the structure in which the fertilizer is dropped and supplied to the fertilizer ditch in the field through the grooving device, the fertilizer may adhere to and accumulate on the inner surface of the hose or the grooving device due to the action of water from the field. When the fertilizer adhered and deposited on the inner surface of such a groover grows and the lower end of the hose is clogged, the sensor that detects the falling state of the fertilizer from the feeding roll directly detects the clog. In the end, when the following fertilizer is filled in the fertilizer application hose after the occurrence of the clogging, and the fertilizer hose reaches the position near the feed roll position, it is detected that the sensor cannot feed. Therefore, the above-mentioned seedling planting without fertilization is carried out for the time lag from the occurrence of clogging near the groove making device to the time when the sensor actually detects the inability to feed. Further, since the sensor detects a fertilizer feeding state for each feeding roll for a plurality of fertilizer-applied strips, whether or not there is an abnormality in any of the plurality of feeding rolls by the alarm means, and
Although it is possible to notify which delivery roll has an abnormality, it is not possible to judge the quality of the fertilizer supply state for each fertilizer application line. Therefore, of the two fertilization strips supplied from one feeding roll, even if the fertilization volume on one side is extremely small, it may not be possible to detect the state, and this is unreliable. It was a thing. The purpose of the present invention is to make the operator directly recognize the occurrence of a clogging due to a rational modification, and to reliably and easily recognize which fertilizer application device has a clogging as described above. And without the hassle of remembering which clogging line is
In addition, the point is to obtain a rice transplanter with a fertilizer application device that has a structure that facilitates the work of clearing clogging and its confirmation. A feature of the present invention is that each line formed in a field scene by a groove grooving device is located at a rear side position of a multi-row planting apparatus which is connected to a rear portion of a riding traveling machine body. In the rice transplanter with a fertilizer application that is provided with a fertilizer device configured to drop-feed the fertilizer in the form of powder that is sent through the pipeline from the fertilizer storage hopper to the fertilizer groove for each A clogging detection sensor is provided inside the opening of the grooving device provided at the lower end of the fertilizer supply path in the rearward opening state, and the clogging detection sensor can detect clogging of any of the clogging detection sensors in the operating section of the passenger traveling machine body. In addition to providing an alarm means that operates based on the above, a clogging occurrence line indicator lamp that operates in response to the clogging occurrence line is provided at a lower position on the rear side of the hopper of the fertilizer application installed in parallel at the rear part of the seedling planting device. Setting The operation and effect are as follows. [Operation] a. As described above, the fertilizer application device is provided with the clogging detection sensor inside the opening of the grooving device provided in the rearward open state at the lower end of the fertilizer supply path of each strip, so for each fertilizer strip, It is possible to quickly detect the presence or absence of the clogging state. In other words, the clogging detection sensor does not detect the feeding state of the feeding roll, but detects the presence or absence of clogging in the grooving device, which often becomes the starting point of clogging. It is easy to detect the presence or absence of clogging. Further, since the clogging detection is performed in association with the fertilizer supply route of each article, compared with the case of determining the presence or absence of clogging in a plurality of fertilizer supply routes from the fertilizer feeding state of each feeding roll, for example,
The supply amount in some of the fertilizer supply routes out of the multiple fertilizer supply routes to which the fertilizer from one feeding roll is supplied is abnormally low, and the supply amount in other supply routes is normal or large. Even in such a case, it is possible to detect the fertilizer supply path in an abnormally small supply state, and thus it is easy to reliably detect clogging for each fertilizer supply path. b. When even one of the clogging detection sensors detects clogging, at the same time, the alarm means provided in the driving unit is activated to make the driver recognize the occurrence of clogging,
At the same time, a clogging occurrence line display lamp provided corresponding to each line on the rear surface of the fertilizer application operates to display. c. Even for the work to clear the clogging at each grooving device, the clogging occurrence line indicator lamp that operates in response to the clogging occurrence line is provided at the lower position on the rear side of the fertilizer storage hopper around the rear of the machine. Since it can be done while looking at, it is easier and easier to see the inside of the grooving device at the mud level near the mud level while trying to visually check the success or failure of clearing the clogging. Easy to do. [Effect of the Invention] a. Above a. And b. From the effect of the above, by providing an alarm means for making the operator recognize the occurrence of clogging and a clogging occurrence line display lamp for indicating which line the clogging has occurred on the fertilizer application side, it is possible to prevent the fertilizer from being applied. The effect is that planting seedlings can be avoided more reliably. B. Above a. And b. Therefore, after the alarm means is activated, it is not necessary to search for or memorize which clogging occurrence line is special, and the clogging can be removed by simply responding to the indication of the clogging occurrence indicator lamp. Therefore, it is not necessary to perform the troublesome work of confirming the clogging location, which is to search for a clogging condition that is difficult to check because it is dirty in the mud.
There is a useful effect in simplifying the work for clearing the clogging. C. Above a. And b. Therefore, the indicator lamp for each fertilizer application line is provided on the fertilizer application side, and only the alarm means is provided in the operating section. It also has the effect of reducing the number of cords that are pulled into. D. Then, the c. Therefore, when the groover is clogged, the crouching operation is performed by turning to the rear of the seedling planting device to remove the clogging of the groover that corresponds to the indication of the clogging occurrence line indicator lamp. To check whether or not it has been performed sufficiently, the clogging occurrence line indicator lamp should be visually inspected, but the grooving device opens rearward, and the clogging occurrence line indicator lamp that operates according to the clogging occurrence line is fertilizer storage. Since it is provided at a lower position on the rear side of the use hopper, it is possible to easily confirm whether or not the clogging elimination work has been sufficiently performed, and the workability of the clogging elimination work is extremely good. E. In addition, the b. And c. From the effect of the above, since the clogging occurrence line indicator lamp that performs the display operation corresponding to the clogging occurrence line is provided at the lower position on the rear side of the fertilizer storage hopper,
Compared with the one that extends high above the hopper to facilitate visual recognition from the rear, it does not interfere with the replenishment of fertilizer to the hopper and does not interfere with other objects when retracted by retracting the aircraft. This is advantageous in that there is no risk of contact with the. An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 11, a rice transplanter is configured by connecting a seedling planting device A to the rear end of the riding type traveling machine body 1 via a link mechanism 3 that moves up and down by the operation of a hydraulic cylinder 2. The seedling planting device A is a transmission case 5 to which power is transmitted from the traveling body 1, a seedling stand 6 on which a mat-shaped seedling W is placed, and seedlings from the seedling stand 6 are planted in the field scene S one by one 5 Five planting arms 7 and three leveled floats 8, 8, 8 arranged side by side in the lateral direction of the seedling planting device A are used for five-row planting. A fertilizer application device B for sending fertilizer to the field is attached.
