Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for discharging and dispersing granules of fertilizer, agricultural chemicals, feed, etc. by the impact of rotating blades.

2. Description of the Related Art Conventionally, there are various types of dispersion devices such as centrifugal force type, impact type, and blower type as means for discharging and dispersing granules of fertilizers, agricultural chemicals, feed, and the like.

It is desired that these well-known scattering devices satisfy requirements such as being able to arbitrarily adjust the direction of release of particles and the spreading width, and that the distribution of the dispersed particles be uniform. None of these devices can be said to fully meet these requirements. Therefore, the present invention provides fertilizer,
The release direction and spreading width of granules of agricultural chemicals, feed, etc. can be adjusted arbitrarily, the structure is simple, no special equipment is required, and the granules can be uniformly dispersed with few failures, and the above requirements are met. The object of the present invention is to provide a device for dispersing granules by the impact of rotating blades.

Embodiments of the present invention will be described below with reference to the drawings. 1st
In the figure, reference numeral 1 denotes the body frame of the spraying device, and this frame 1 has a pitch 2 at its front end that is connected to the rear of a tractor (not shown), and a pair of left and right running wheels connected to the lower part of the rear end via a shaft 3. Equipped with 4 wheels. This frame 1
A hopper 5 for accommodating granules such as fertilizers, agricultural chemicals, and feed is provided at the top of the machine, and a discharge port 6 is provided at the bottom of the hopper 5, which is elongated in the longitudinal direction of the machine.
This discharge port 6 is divided into two parts, front and rear, by a branch plate 7 at the center in the length direction, and a feed roll 8 is disposed above the discharge port 6 along the length direction, and its rotation axis Ba is It protrudes outside the hopper 5 and is pivotally supported by the frame 1. As the feed roll 8 rotates, the granules housed in the hopper 5 are discharged from the discharge port 6 in a thin layer. A rotating blade casing 9 is provided below the hopper 5.

This casing 9 has two covers 9b, 9b with hollow fan-shaped planes provided on a circular base plate 9a, facing each other, and the intersection between the axis of the base plate 9a and the cover parts 9b, 9b. The rotating shaft 11 of the rotating blade 10 is inserted and supported between the rotating blade 10 and the rotating shaft 11 of the rotating blade 10 . The rotating shaft 11 is vertically projected upward from a transmission 12, which will be described below, provided below the base plate 9a, and rotates in a predetermined direction. Supported by This casing 9 includes a rotating blade 10 that rotates in the direction of the arrow in FIG.
is located at the exit portion that moves within the cover portion 9b and emerges onto the base plate 9a, and the lower end of the discharge port 6 faces so that the discharge direction can be adjusted, and the discharge port 6 falls in a thin layer from the discharge port 6. The particles collide with the rotating blades 10 and are ejected in the radial direction. Further, the length of the discharge port 6 and the length of the rotating blade 10 are made to be approximately the same. The rotating blade 10 has a boss portion 10a that is inserted through the rotating shaft 11 and can be adjusted up and down with a screw or the like.
It is attached to four support rods 10b fixed at angles of 90 degrees in the radial direction so that it can rotate in a horizontal plane, and the angle formed with the vertical plane intersecting the direction of rotation, that is, the support rod The mounting angle with respect to the rod 10b is adjustable with a screw or the like.

The transmission 12 has an input shaft 13 protruding toward the front side of the machine body, the tip of which is connected to the tractor PTO shaft to receive rotational power, and an output shaft 14 protruding to the opposite side of the input shaft 13 and the rotary shaft. 11 so that the L1 power can be transmitted at different speeds.

A belt transmission system 15 is provided between the rear end of the output shaft 14 and the rear end of the rotary shaft 8a, and rotates the feed roll 8 in a predetermined direction. The granule dispersing device configured in this way is towed by connecting pitch 2 to a tractor,
While traveling by the running wheels 4, the input shaft 13 and the transmission 1
2, the output shaft 1 is connected to the feed roll 8 via the male belt transmission system 15, and the rotary blade 10 is connected to the output shaft 1 via the rotating shaft 11.
are rotated in respective predetermined directions, the particles are dropped in a thin layer from the discharge port 6, and are struck by the rotating blades 10 to be scattered on both sides of the spraying device traveling in the direction of the arrow in FIG.
At this time, the flow rate of the granules accommodated in the hopper 5 is adjusted by changing the rotation speed of the feed roll 8, and the granules that are struck by the rotary blades 10 are moved closer to the center of rotation, where the radius of rotation is smaller. The flight distance is small in the part where the radius of rotation is large, and the flight distance is large in the part away from the center of rotation where the radius of rotation is large, and the ball is spread evenly. Furthermore, the rotational speed of the rotary blade 10, the installation angle of the blade, the lower end position of the discharge port 6, and the rotary blade 1
By arbitrarily adjusting the distance to 0 (vertical position), etc., a desired scattering width and distribution state can be obtained. Furthermore, when viewed as a plane projection, the particles are radiated in a direction perpendicular to the length l direction of the discharge port 6, so by adjusting the discharge direction of the discharge port 6, the radiation direction can be changed arbitrarily. can. In the above embodiments, the present invention was applied to a device towed by a tractor, but the present invention can be similarly applied to an aircraft-mounted type, a tractor-mounted type, a trailer-mounted type, etc. It is.

As explained above, according to the spraying device of the present invention, the rotary blades are used to hit and radiate the particles falling and supplied in a thin layer, and the installation angle and vertical movement of the rotary blades are made possible. The release direction and scattering width of the particles can be adjusted as desired, and the particles can be evenly dispersed.

Further, since the structure is extremely simple, it is easy to handle, has few failures, and can be supplied at a low price.
