Description

[Detailed Description of the Invention] [Industrial Application Field] The invention is to provide a perforated delivery roll in which a fixed amount of fertilizer or seeds is received in a delivery hole and delivered while rotating intermittently. This invention relates to a feed-out roll drive device in a fertilizer application machine, etc.

[Conventional technology]

Conventionally, in fertilizer applicators, etc., which are configured with a perforated feed-out row A having a large number of concentric feed-out holes, and which is mounted on a shaft for intermittent rotation at the bottom of the entire hopper, a gear case above the feed-out roll is inserted from the outside. The structure was such that the feed-out row A/ was rotated by a rotating shaft hanging down from the gear case by transmitting power so as to rotate intermittently.

[Problem that the invention seeks to solve]

With such a structure, the gear case makes the upper side of the feed roll larger and the transmission structure also becomes larger, and the hopper becomes higher above FRft, making the rock slag unstable and causing transmission problems. In addition, the structure was complicated and the system maintenance was not easy to perform, which caused nine problems.

[Means for solving problems]

Undiscovered has solved this problem and has a simple structure that can be downsized and ensure good transmission.Therefore, it hangs down from the center of the feed roll and connects to the bottom of the next rotating shaft. - The base of an arm whose tip end is connected to a swinging rod that reciprocates in a million directions is fitted, and a one-way clutch is interposed in a part of the rotating shaft between the arm and the feeding roll. It is composed of

[Effect]

Therefore, when the arm is reciprocated by the swinging rod that reciprocates in one direction, the one-way clutch installed in the rotating shaft rotates intermittently in one direction, causing the payout roll to rotate intermittently in one direction. Fertilizer or seeds will be delivered.

〔Example〕

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

Figure 2 shows a side view of a part of the rice transplanter, and shows each flow.
Above +8+, a seedling take-out board (IG) is placed horizontally across the top of each planting case (9). ) The planting arm (I-shaped) has a planting claw α4 at its tip and a driven arm α at its rear end.
! A feeding case (3) is provided at the bottom of each hopper (3) which is connected to each other, and a fertilization type αe is extended laterally from the middle part of each planting arm 0, and supported by a stay αη above. 3a) A fertilizing hose α is vertically installed, a guide tube αlt is vertically installed from the lower part of the fertilizing hose αe, and a soil plate (1) is vertically installed on the rear side of the guide I. Configure similarly.

In FIGS. 1 to 3, FIG. 1 shows a cross-sectional view of the feeding section, and the upper side of the feeding case (3a) has a flommet l-c! A discharge port (C) is formed in which D is detachable, and the fertilization hose α is installed at the bottom of the feeding case (3a).
A lower plate Q4 having a dropout opening @ facing above υ is stretched, and above the lower plate Q4, a number of feeding holes fl) are formed at predetermined intervals on a concentric circle around the outer periphery. A dish-shaped feed roll (2) is rotatably joined, and above the feed roll /I'+21, there is a supply port c on the opposite side of the outlet (c). A top plate (a) having a diameter of 9 is stretched at intervals, and a vertical rotation shaft (4) is fitted into the metal part provided at the lower center of the feeding case (3a). (4) The upper end part is fed out to the above-mentioned row /l/ +
A one-way clutch (a boss (6a) is fitted to the lower part of the rotating shaft (4), which is fitted into the center of the metal part 21 and fixed thereto, and hung vertically below the metal part (2)). The boss (6a
) Extending in the radial direction from the outer periphery of the arm +61, the tip of a swinging rod (5) that reciprocates in one direction is interlocked with the tip of the swinging rod (5) via a linking tool @, and connected to the driven arm α. The rear end of the swing rod (5) is interlocked with the upper end of the swing arm that swings in conjunction with each other via a link O1.

FIG. 4 and FIG. 5 show another embodiment, which is constructed in substantially the same way as the embodiment described above, as indicated by the same reference numerals, but with a rotating shaft (
A one-way clutch (7) is fully interposed between the upper part of 4) and the feed roll (2), and the boss (6a) is fixed to the lower part of the rotating shaft (41) by fitting the locking pin Gυ. do.

Further, the guide tube (11) whose upper part is fully fitted and connected to the lower end of the fertilizer hose α mallet is formed of an elastic material, and is formed into a curved surface like the motion locus 00 of the fertilizer application type (Ie). At the same time, there is a horizontal strip 11 on the upper part of the back.
3t- is formed, and a vertical slit is formed from the center of the slit to the lower end, but as shown in Fig. 8, a slit is formed in the center of the flat back surface. , υ with a slit formed in the center of the V-shaped sloped back surface as shown in FIG. 11, υ with a slit c13 formed on one side of the back surface as shown in FIG. The lower end of the guide tube α-yu is provided with an opening (b) that is rounded as shown in FIG. 9 or pointed as shown in FIG. 10 so as to be connected to the slit (to). Form.

The tip (16a) of the fertilizer mold (le) may be rounded and concave as shown in FIGS. 13 to 15, or may be formed into a concave shape as shown in FIGS.
) at the tip of the protrusion (16b), or the first
As shown in Figure 8, the tip (16a) has a concave curved surface (16c).
' to form and compose.

Therefore, during rice planting work, the planting claw α4 scrapes the seedlings from the seedling removal plate α and plants them on the rice field.
5) As shown by the upward arrow (a), the arm (6) is to be reciprocated in one direction, and the arm (6) is to be reciprocally rotated. ) will feed out a predetermined amount of fertilizer received in the intermittent rotating feeding hole (1) in one direction from the outlet device to the fertilizing hose αB.

A predetermined amount of fertilizer flowing down the mouth of the fertilizer application hose α is guided through the guide tube a.
However, as shown in Fig. 6, the tip (16a) of the fertilizing type ae, which swings with the pronged claw α, reaches the upper slit (to). The fertilizer is then pushed into the slit 03, descending along the inside of the guide tube 01, and pushed down on the fertilizer inside.The opening and closing opening at the bottom is pushed open and a predetermined amount of fertilizer is pushed into the field for planting. This means that four-row fertilization can be applied near the seedlings.

[Effect of the invention] In this way, the uninvention is that the feed roll can be rotated intermittently from the lower side by the swinging rod via the one-way clutch, and the lower side of the feed roll is simply turned into the fertilizer supply side. This means that the upper hopper can be made more compact and can be made into a small groove, making it possible to have a stable mounting structure without the upper hopper being high above the fan body, and also making it easy to maintain. It has the advantage of being able to reduce costs, and to be able to take full control of the system.
