Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for dispensing granular materials such as fertilizers and seeds, and more specifically, a device for dispensing granular materials such as fertilizer and seeds, and more specifically, a device for dispensing granular materials such as fertilizers and seeds, and more specifically, a device for dispensing granular materials such as fertilizers and seeds, and more specifically, a device for dispensing granular materials such as fertilizers and seeds. Regarding equipment. In conventional devices of this kind, in order to stop feeding, a single drive rotation shaft that rotates the feeding rolls of these feeding devices arranged in a straight line is stopped, thereby stopping the feeding action of each feeding roll. was.

However, there is a drawback that each of these feeding devices cannot be stopped individually. This invention is extremely convenient and has a simple structure, in which a large number of feed rolls are skewered by a single rotating shaft to transmit power, but the rotation of each feed roll can be stopped individually. The purpose is to create a device.

Unable to achieve this objective, this invention is based on the hopper α→ (
At the bottom of the 1i19, there is a plurality of granular material feeding devices each having a feeding roller (o-)I/Q8) which feeds out the granular material in the hopper while being rotated by transmission. Arranged so that they overlap in a straight line, a single rotation axis OQ

It is wedged and is movable in the axial direction. Then, this clutch rotating body (c) is rolled (c) by a spring (c).
18a), so as to engage the clutch pawl Q9 of the clutch rotating body (c) with the clutch pawl (b). Further, this clutch rotating body (c) is provided with a relatively wide shifter engagement groove (24a).

(4) is the shifter shaft, which is constructed by cutting the shaft into a half-moon shape.
The lever (A) is fitted into the shifter retaining groove (24a) and is supported by the shaft, and by rotating the lever (A), the clutch rotating body (C) is rotated by the spring (C).
(c) It is provided so that it can be moved against the clutch, allowing one person to "disengage" the clutch.

The handle (A)... is an operating tool, and in the example shown, one end of the round bar is locked to the lever (A), and the other end is extended toward one end of the rotating shaft Qe, and the fertilizer feeding part is A [Yes] is attached to the frame (1) of the fertilizer application machine which is supported on the passenger car body (1).It is configured so that it can be locked in the state where it is pushed into the panel (3) and the state where it is pulled out. are doing. (31a), (3
1b) is a locking hole for the operating tool.

02 is an upper mold tube, and the above-mentioned feeding part case 1. It is attached to the bottom end of the funnel attached to the outlet of α.

(Incorporated Foundation), 03... is a fertilizer transfer pipe, the base of which is connected to one end of the upper mold pipe, and the other end of which is connected to the cultivation grooves attached to the land leveling flow of the rice transplanting device (6) (10a) and (10b), respectively. It is inserted into the container.

2) is a blower that is attached to the front right side of the passenger car body (1) and rotated by transmission, and blows air through a duct (to) into the air tank (to) attached to the lower front side of the passenger car body (1). It is piped to blow in.

(b) is a blower pipe that connects the upper mold pipe and the air tank (to).

In the figure, symbol (2) is a support frame for supporting the fertilizer application device on the passenger vehicle body (1), and symbol (A) is a flexible transmission shaft.

Next, to explain in detail the operation of the upper side, first, seedlings are accommodated in the seedling tank (8), and each hopper 〇Φ, (10
Granular fertilizer is supplied inside the machine, and an engine (not shown) transmits the rotation of each part.

Then, the rice transplanting device (6) is towed and the soil leveling float (1
Seedlings are planted at predetermined intervals on the soil leveled in steps 0a) and (10b). On the other hand, the rotation shafts θ of the fertilizer applicator are transmitted and rotated by the transmission shaft ■, and at this time, each clutch rotating body is placed in the imaginary line connection state shown in Fig. 5, and the clutch is
If set to ``ON'', each feed roll a8), α barrel, etc. will be rotated by transmission, and the granular fertilizer in the hoppers 〇→, aQ will be fed out little by little. At this time, air is sent from the blower (C) through the air tank (G) to the starting end of each upper mold pipe, so that the delivered fertilizer is transferred to the fertilizer transfer pipe (C), (C)... (10a).

(]Ob) is sent into the groove-making device (B), which has been cut several times, and is applied to the created grooves.

In this way, during work, if there is a row near the edge of a ridge where you want to stop fertilizing, the clutch rotor (c) of the feeding device
Simply pull the operating tool on the lever attached to the shifter shaft corresponding to the lever as shown by the solid line in FIG. At this time, the clutch pawl (c) of the clutch rotating body (c) comes off from the clutch pawl (b) of the feeding roll (18a), and the feeding roll l
rotation (towards the end) is stopped.

Therefore, fertilization in that area is stopped.

2. Since the present invention has the above-described configuration, it is possible to make a compact device in which a plurality of fertilizer application devices can be integrally constructed by attaching a feed roll to a single rotating shaft in a skewer-like manner, and each of the devices can be constructed compactly. The effect is that the rotation of each delivery roll can be stopped individually.
