Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for supplying granular fertilizer to rice fields.

Conventionally, when applying fertilizer to paddy fields where rice and rushes have been cultivated, workers store granular fertilizer in a plastic container, carry it with them, walk across the rice field, and use their hands to spread the granular fertilizer in the plastic container. This invention has the disadvantage that it requires a lot of time and effort to spread fertilizer. In order to solve the above-mentioned disadvantages, the present invention installs a rope at the outlet of the irrigation pipe that supplies water from the irrigation canal to the rice fields. This metering fertilizer feeder feeds a fixed amount of fertilizer into the rope and mixes it with irrigation water, which eliminates the need for workers to walk across the paddy fields and enables efficient fertilization. This is a characteristic feature.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

A casing 21 in which a scraping impeller 20 is vertically supported is installed on the upper surface of the underframe 1, the lower end of the flopper 9 is communicated with the upper surface of the casing 21, and the discharge chute 10 is communicated with the lower surface of the casing 21. A flow control plate 11 is inserted into the communication portion between the discharge chute 10 and the casing 21 and linked with the threaded rod 12 on the top surface of the underframe l, thereby interlocking the prime mover 13 and impeller 20 installed on the top surface of the underframe 1. This is made to constitute the third fertilizer quantitative feeder 14c.

4. Support the casing 4 on the upper surface of the underframe 1 at an appropriate height, install the reducer 22 on the upper surface of the underframe 1 below the casing 4, and insert the reducer 22 through the shaft hole of the bottom plate of the casing 4. A rotating shaft 5 is provided protrudingly provided, a disc 23 is fixed to the rotating shaft 5 on the upper surface of the bottom plate of the casing 4, and a hopper 9 is mounted on the underframe l, with a skirt 24 attached to the lower end opening so that it can be adjusted up and down with a handle 25. The skirt 24 at the lower end of the hopper faces the disk 23 by being installed on the more protruding support 26, and the pressure reducing plate 7 is fixed to the upper end of the rotary shaft 5 protruding from the lower end of the hopper 9. 8, a discharge port 3 is cut in the front of the casing 4, the discharge port 3 is made to face the upper end of the discharge shoe 11, and one end of the souffle bar 28 is secured to a frame rod 27 protruding from the upper surface of the underframe l to discharge the air.

At the same time, an auxiliary souffle bar 28' is provided to protrude from the tip of the souffle bar 28 to the lower surface of the skirt 24, and the motor 13 on the upper surface of the underframe 1 and the speed reducer 22 are interlocked.
This is made to constitute the fertilizer quantitative feeder 14d. In the figure, 29 is a rice field, 30 is a ridge, 31 is a rope area, and 3
2 indicates an irrigation canal.

Next, the effects of the present invention will be explained with reference to embodiment figures.

When fertilizing paddy rice and rushes planted in the paddy field 29 using the fertilizer quantitative feeder 14 according to the present invention,
A rope section 31 is installed near the ridge 30 in the irrigation canal 3.
2, water is supplied to the ridge 30, and a fixed amount of granular fertilizer is supplied into the mesh basket 31 by the fertilizer quantitative feeder 14, and the fertilizer is automatically supplied to the paddy field 29 along with water by feeding it into the mesh basket 31 and dissolving it. The fertilizer quantitative feeder 14 is required to release a certain amount of granular fertilizer, and in the first fertilizer feeder 14a, the rotary shaft 5 is interlocked with the prime mover 13, and The impeller 6 and the pressure reduction plate 7 are rotated within the casing 4, and the granular fertilizer flowing down from the periphery of the pressure reduction plate 7 into the casing 4 is carried by the impeller 6 to the discharge port 3.
The amount of the liquid falling can be adjusted by adjusting the opening width of the discharge port 3 using the flow rate adjustment plate 11. Since the load of the fertilizer in the hopper 9 is once received by the pressure reducing plate 7, the impeller 6 can be rotated smoothly without applying pressure to the impeller 6. The second quantitative fertilizer feeder 14b discharges a fixed amount of fertilizer while rotating a screw 16 at the lower end of the hopper 9, and the amount of fertilizer flowing down can be adjusted by changing the speed of the rotation of the screw 16. The third quantitative fertilizer feeder 14c rotates the impeller 20 within the casing 21 and causes the fertilizer received at intervals between the blades to flow down to the discharge chute 10.
4d, while rotating the disc 23 within the casing 4, the skirt 24 fitted to the lower end of the hopper 9 is adjusted up and down, and the granular fertilizer released into the disc 23 is transferred to the souffle bar 2.
8 and an auxiliary souffle lever 281 to flow down from the discharge port 3 of the casing 4 to the discharge chute 10.

Therefore, by installing the fertilizer quantitative feeder 14 according to the present invention on the ridge of a paddy field, supplying a fixed amount of fertilizer into the rope section provided in the paddy field, and supplying water from the irrigation canal into the rope section, granular fertilizer can be converted into liquid fertilizer. As a result, it automatically permeates into the paddy field, and has the remarkable effects mentioned above, such as making it possible to improve the efficiency of fertilization in the paddy field.
