Description

[Detailed Description of the Invention] The present invention relates to a structure of a feeding section in a fertilizing section of a rice transplanter or the like.

In other words, in the fertilizing section of a rice transplanter, etc., which is configured to dispense a fixed amount of fertilizer by a dispensing roll attached to the dispensing section at the bottom of the tank, the precision is ensured by ensuring that the dispensing roll rotates and dispensing a fixed amount of fertilizer. To provide a fertilizer that can perform high-level fertilizer application work, accurately dispense fertilizer without adhering to the feed groove of a feed roll, and has a simple structure so that it can be carried out suitably. be.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a partially cutaway side view of the rice transplanter, where 6 is a float, E is an engine, 7 is a wheel, and 8 is a side view of a rice transplanter.
1 is a handle, 9 is a seedling stand, 10 is a planting claw, and 11 is a planting depth adjustment lever, which is constructed in the same manner as the conventional structure.

Further, a fertilizer tank a is mounted above the machine on the front side of the seedling platform 9, and a hose 12 is fed out from the bottom of a feeding section A installed at the bottom of the tank a.
A trencher 13 is installed vertically on the rear side of the float 6, which is inward of the planting position by the planting claws 10.
A soil cultivator 14 is installed behind each of these, and the lower part of the feeding hose 12 is connected to the rear of the trenching section 13, and a certain amount of fertilizer is placed in the trench created under the rice field by the trenching device 13. The structure is similar to the conventional structure, and is installed so that side-row fertilizer can be applied by sequentially introducing fertilizer.

A feeding roll B is rotatably mounted on an axis inside the feeding portion A below the tank a,
At four equally spaced positions on the outer periphery of the feeding roll B, feeding grooves 2 having a constant depth and parallel width and opening both ends and the outer circumferential side are formed, and each feeding groove 2 has a parallel width and a constant thickness. The bottom plates 3 having the base plates 3 are fitted together so as to be slidable in the radial direction, and pins 3a, 3a are provided to protrude from both ends of each bottom plate 3, respectively, to protrude shortly outward from both ends of the feed roll B. .

Further, the rotating shaft 1 is fitted and fixed in the central shaft hole 15 of the feeding roll B via a key 16, and the rotating shaft 1 is inserted into the side wall portions 4, 4 at both ends close to both end surfaces of the feeding roll B via metals 17, 17. The shaft 1 is mounted on a shaft, and a flexible transmission shaft 18 that transmits power from the fuselage is connected to the end 1a of the rotary shaft 1, and pins 3a of each bottom plate 3 are mounted on the inner surfaces of the side walls 4, 4. 3a
ring-shaped guide grooves 5, 5 into which the
are formed, respectively, and the guide grooves 5, 5 are installed so that the ring centers of the guide grooves 5, 5 are eccentrically downward from the axis of the rotary shaft 1.

Brushes 1 are provided on both sides of the upper side of the feed roll B.
9 and 19 are configured so that they are in contact with each other.

Therefore, in order to perform side row fertilization, the rotating shaft 1
When the feed roll B rotates as shown by arrow A, each bottom plate 3 rotating together with the feed roll B slides in the guide grooves 5, 5 in which the pins 3a, 3a at both ends are eccentric. It will slide in the radial direction as shown by the arrows B.

As shown in Fig. 2, when the feeding groove 2 comes upward so as to look below the tank a, the bottom plate 3 is positioned at the bottom side of the feeding groove 2, and the inside of the feeding groove 2 is filled by a predetermined amount. of fertilizer,
The fertilizer is received as it is, and the feeding groove 2 is partitioned by the brush 19 and rotated downward.
As shown on the right and bottom sides of FIG. 2, the bottom plate 3 slides toward the outer periphery, and the bottom plate 3 is pushed out all the way to the outside of the feeding groove 2 at all points downward. This means that all the fertilizer in the container can be pushed out and a fixed amount of fertilizer can be applied.

In this state, the bottom plate 3 reciprocates within each feeding groove 2, so that fertilizer does not adhere to the feeding groove 2.

In this way, the present invention has been proposed in the fertilizing section of a rice transplanter, etc., which is configured to dispense a fixed amount of fertilizer by a dispensing roll mounted on the dispensing section at the bottom of the tank. A plurality of feeding grooves are formed with a constant depth in the radial direction and extending over the entire length in the axial direction, and a bottom plate having pins at both ends that protrude outward from both ends of the roll is slidably fitted into each feeding groove. , ring-shaped guide grooves into which each pin is slidably fitted are formed eccentrically with respect to the axis of the feed roll on the fixed side walls close to both ends of the feed roll. As the bottom plate rotates, both pins of the bottom plate slide in the guide groove, and the bottom plate slides in the feeding groove all the way in the depth direction, so that a certain amount of fertilizer can be received in the feeding groove. At the same time, all of the fertilizer can be reliably pushed out by the bottom plate on the lower side, allowing highly accurate fertilization work to dispense a certain amount of fertilizer.Furthermore, the sliding of the bottom plate allows fertilizer to be pushed out into the feeding groove. It has the feature that it is possible to accurately dispense the measured amount without adhesion, and that it can be suitably implemented with a simple and simple structure.
