Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a granular material dispensing device such as a fertilizing device or a seeding device.

BACKGROUND ART Conventionally, there has been a device for dispensing granules as disclosed in Japanese Utility Model Application Publication No. 59-87215.

This conventional device has a structure in which a plurality of granular material dispensing units are arranged in parallel in horizontal rows, and the dispensing amount of each dispensing device is adjusted at once by a single rotary operation shaft. It is.

Problems to be Solved by the Invention In the conventional device described above, the rotary operation shaft side for adjustment is integrally supported by a bearing on the case side 1 of the feeding unit 1, and the gear supported on the shaft is The structure was such that it was impossible to assemble or disassemble the product without removing it from the shaft. Therefore, there is a drawback that the number of man-hours during assembly increases, leading to high costs.

Means for Solving the Problems In order to solve the above problems, the present invention requires the following technical means.

That is, in this invention, a hopper 1 for storing granular fertilizer and seeds is provided in the upper part, and in the lower part of the hopper 1, which communicates with the lower end discharge port, there are dispensing grooves (A) in the axial direction at a predetermined pitch on the circumferential surface. The formed female type feeding roll 13a and a projection body (
A feeding chamber (c) is provided in which a feeding mechanism consisting of a male feeding roll 13b having a shaft (b) is mounted on an internal shaft, and this feeding chamber (c)
A shaft 11 having a threaded portion 11a that is the same as the shaft core of the rotary shaft 7 is provided on one side in the axial direction of the rotary shaft 7 inserted through the rotary shaft 7. A plurality of granular material feeding units are arranged in parallel in the axial direction, sharing the rotating shaft 7, in which the gear 15 is connected to the female type or male type feeding roll so as to be integral only in the axial direction. A pinion gear 24 that meshes with the adjusting gear 15 of each of these feeding units is attached to a single feeding amount adjusting shaft 20 so as to be movable in the axial direction and integrated in the rotational direction, and this adjusting shaft 20 is A particulate matter dispensing device which is detachably installed directly or indirectly in a dispensing case 6 forming the dispensing chamber (c), and is provided with an operating means which can rotate the regulating shaft 20 as appropriate.

A threaded portion 11a is formed on the outer circumferential surface of this base side.

Reference numeral 13 denotes a feeding roll, which is slidably fitted into a female feeding roll 13a having feeding grooves (A) formed in the axial direction at a predetermined pitch on its circumferential surface, and into the feeding grooves (A) of this feeding roll 13a. It consists of a male type feed roll 13b having a protrusion (B), and this female type feed roll 13a has metal bushings 14, 14 press-fitted into its inner periphery so as to be freely rotatable on the tip side of the feed roll support shaft 11. One male type feeding roll 13b is inserted and supported, and a bush 16 is attached to the boss portion of a feeding amount adjustment gear 15 screwed onto the threaded portion 11a of the feeding roll support shaft 11.
It is rotatable through the bushing 16 and is engaged in the axial direction through a collar 18 which is received by the flange of the bushing 16 and a snap ring 17 .

Reference numeral 20 denotes a feeding adjustment shaft, which has a protrusion 21 on the inner surface of a detachable frame 21 that can be engaged with and detached from the side surface parallel to the rotation axis of each feeding case 6.
a and is rotatably supported on this. The detachable frame 21 can be engaged and detached using a hook 22.22 on the case side and a pin 23.23 on the detachable frame side.

Reference numeral 24 denotes a pinion gear, which is rotatably inserted into and supported by the feeding adjustment shaft 20 in a state in which it is biased to one side by a C-shaped retaining ring 25, a flat washer 26, and a spring 27; A pentagonal drive element 28 screwed to the pinion gear 24 is fitted into a pentagonal hole bored in the side surface of the pinion gear 24.

In this way, the pinion gear 24 attached to the feed-out adjustment shaft 20 bearing the bearing on the detachable frame 21 is positioned so that when the detachable frame 21 is attached to the feed-out case 6, the pinion gear 24 and the gear 15 are engaged. configured to fit. When the pinion gear 24 is moved against the spring 27, it is disengaged from the drive element 28 and the gear 24 becomes rotatable, and the gear 15 can be rotated manually and independently, allowing independent feeding adjustment. It is configured as follows.

Reference numeral 29 denotes a manual adjustment handle, which is bendably attached to one end of the feeding adjustment shaft 20, and is configured so that it can be bent and locked onto the machine frame 30 side of the fertilizer application device.

In addition, the symbol 31 in the figure is a fertilizer transfer pipe, 32 is a fertilizer regulating frame, 33 is an operating lever with a ratchet mechanism that drives the rotating shaft 7, and 34 is a hopper lid.

Next, the operation of the upper side will be explained.

First, the hopper 1 is removed from the dispensing case 6, the discharge ports 1a and la are closed with shutters 2, 2, granular materials such as fertilizer are stored inside, and then the hopper 1 is attached to the dispensing case 6 again.

In this case, when the hopper 1 is placed near a wet area near a paddy field and fertilizer is put into the hopper 1, even if the shutter 2 tries to get wet, the shutter 3 itself will get wet because it is covered by the boots 3. This prevents fertilizer from adhering to the soil.

Then, when the discharge port 1a is opened with the shutter 2 and the rotating shaft 7 is rotated appropriately, the rotating body 10 fixed to the rotating body 10 is rotated, and the driving claw 10a and the driven type 13c of the female type feeding roll 13a are rotated. The engaged rolls 13a are rotated by transmission. The male type feed-out roll 13b that engages with the feed-out groove (A) of this roll 13a is also naturally rotated by transmission, and the fertilizer enters the feeder f & (A) and is rotated, so that the fertilizer is fed downward in fixed amounts. and is discharged from the lower discharge [16d].

When adjusting the feeding amount of each feeding device, the pinion gear 24 of the feeding device is moved against the spring 27 to separate the gear 24 from the driver 28, and the adjusting gear 15 is manually rotated. death.

It is preferable to move and adjust the gear 15 in the axial direction to adjust the movement of the Ia type feed roll 13b, thereby changing the effective dimension of the feed groove (A).

In addition, when adjusting the feeding amount of each feeding device at once,
The adjustment handle 29 rotates the adjustment shaft 20, and the adjustment gears 15 and 15 are rotated through the pinion gears 24 and 24 to adjust the movement of each male delivery roll 13b at once, thereby adjusting the effective dimension of the delivery groove (A). It is a good idea to change the .

In this way, in the configuration where each feeding device can be adjusted at once, the feeding adjustment shaft side can be easily attached to and detached from the feeding case 6, so the transmission mechanism on the feeding adjustment shaft side can be attached to the feeding case 6. It can be assembled and disassembled extremely easily.
