Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rocking type spreader. More specifically, the present invention relates to a rocking type spraying machine for spraying powdered materials such as fertilizers, and objects to be sprayed such as granules.

[0002]

2. Description of the Related Art As a conventional rocking type spraying machine, there is known, for example, Jikho Sho 62-25077 "Adhesion preventing device for rocking type spreading machine". In the swing type spreader, a sub hopper is provided below the hopper. The sub hopper oscillates when the oscillating shaft vertically passing through the center is sequentially rotated in the forward and reverse directions. A spray pipe is attached to the sub hopper, and the tip of the sub hopper is horizontally reciprocated by the swing of the sub hopper. Then, the object to be scattered falls around the swing shaft of the sub hopper through the opening of the shutter of the hopper. Therefore, the objects to be scattered are sprayed by the centrifugal force due to the swing of the sub hopper and the spray tube. Furthermore, actual public Sho 62-27070
In the "oscillating fertilizer spreader", a large number of drop holes are radially formed around a central hole in a bottom plate opened below the main hopper.

[0003]

By the way, in the conventional rocking type spreader, the sub hopper 1 of the conventional rocking type spreader is used.
01 and the central section of the spray pipe 102, FIG.
As shown in FIG. 6 which illustrates the tip end surface of the spray pipe, the swing shaft vertically extends through the center of the sub hopper 102, around which the objects to be scattered fall from the hopper.

Normally, the material to be sprayed is sprayed by centrifugal force due to the oscillating action of the sub hopper and the spraying tube, but the material to be sprayed 104 such as Berg fertilizer having a small specific gravity and a large amount of fibers and organic manure such as chicken manure is sprayed. There was a problem that it did not move to the tip of the pipe but performed a dance action in the sub hopper and accumulated on the inner wall.

[0005]

Means for Solving the Problems

It is characterized by comprising a hopper and a sprinkling tube which is swung below the hopper and which is provided with a receiving port for receiving the material to be sprinkled from the hopper only at a tip side position which is a certain distance from the swing center. Oscillating spreader,

[0007] to provide.

[0008]

The object to be scattered supplied from the hopper is supplied to the receiving port provided at the tip side position which is located at a certain distance from the swing center of the spray tube. Therefore, the material to be sprayed is sprayed from the tip of the spray tube without staying in the receiving port.

Embodiment FIG. 1 showing a central cross-sectional view of an embodiment of the present invention, FIG. 2 showing a perspective view of the same main portion, FIG. 3 showing a schematic central cross-sectional view of the spray pipe, and a side view of the spray pipe. 4 will be described.

Reference numeral 11 is a frame. 12 is a top bracket and 13 is a lower bracket. The top bracket 12 and the lower bracket 13 are fixed to the frame 11, and are attached to the rear part of the tractor that drives and moves the swing type spreader.

Reference numeral 21 is a support box. The support box 21 is formed in a box shape and has a drive unit internally, and is attached to the center of the frame 11. That is, the support box 21 supports the main shaft 22. Reference numeral 23 is a cam shaft that is eccentric to the main shaft 22. The cam shaft 23 is attached to the outer periphery of the main shaft 22. Reference numeral 24 is a tracking member. Chasing member 24
Are attached to the outer periphery of the cam shaft 23. Reference numeral 25 is a swing frame. The oscillating frame 25 has a U-shape and is used as a follower member 2.
4 is supported at both lower ends which are free ends. The upper surface of the swing frame 25 is supported on the support box 21 by a swing shaft 26. The center point of the swing shaft 26 is made to coincide with the swing center of the eccentric cam shaft 23. 27 is an input shaft. Power is transmitted to the input shaft 27 from the PTO shaft of the tractor. Reference numeral 28 is a flywheel that transmits the power input from the input shaft 27 to the main shaft 22.

Reference numeral 31 is a distribution pipe. The spray pipe 31 has a horizontally long quadrangular cross section, and has a base fixed to the swing frame 25. Reference numeral 32 is a receiving port provided at the base of the spray pipe 31. As shown in FIG. 7, the receiving port 32 has the swing shaft 26.
Is provided at a position away from, and the bottom surface is formed as an inclined bottom surface that is inclined toward the tip. 33 is a protrusion. In the conventional spray pipe as shown in FIG. 6, the objects to be scattered tend to collect on the side portions, but in this embodiment, the accumulation of the objects to be scattered is prevented from being formed on the side surface, and the protrusions are formed. 33 is
It is provided in the middle of both sides of the spray pipe 31. Protrusion 33
Prevents the material to be scattered from adhering to the inner surface.

Reference numeral 41 is a hopper. 42 is a hole provided on the bottom surface of the hopper 41. The holes 42 are the distribution tubes 3
It is provided in the upper part of the receiving port 32 provided in 1. 42 is a rotating shaft. The rotating shaft 42 is installed vertically to the center of the hopper 41. The rotating shaft 42 is covered with a boss 43 and is connected at the upper part of the rotating shaft 42, and an agitator 44 is provided at the lower end of the boss 43 so as to project outward. 45 is a seat plate. The seat plate 45 is attached to the bottom surface of the hopper 41.
A gear 46 is attached around the lower portion of the rotary shaft 42 exposed to the outside of the hopper 41. 47 is a shutter. The shutter 47 is slid parallel to the lower surface of the seat plate 45 and adjusts the opening amount of the hole 42 to adjust the falling amount of the object to be scattered. The opening and closing of the shutter 47 is performed by remote operation of an electric motor or the like as necessary.

Reference numeral 51 is a support shaft. The support shaft 51 is the swing frame 2
5 is attached to the gear 46 side from the swing shaft on the upper surface. The rotation of the support shaft 51 is restricted by the spring 52. 5
3 is a nail. The base of the claw 53 is attached to the support shaft 51, and the tip of the claw 53 is locked to the tooth of the gear 46.

Next, the operation of the embodiment will be described. When power is transmitted from the tractor PTO shaft and the input shaft 27, flywheel 28, and main shaft 22 rotate, the cam shaft 23 rotates. The follower member 24 is swung in plan view by the amount of eccentricity of the cam shaft 23. That is, the swing shaft 26 provided on the upper surface of the swing frame 25 swings in the direction of FIG. At this time, the spray pipe 31 attached to the swing frame 25 swings together in the F direction.

When the swing frame 25 swings around the swing shaft 26 as a fulcrum, the support shaft 51, which is appropriately displaced, swings and the claw 53 moves. At this time, the claw 53 is
Is transmitted to rotate the rotary shaft 42 in one direction, so-called claw clutch deceleration transmission. As the rotating shaft 42 rotates, the agitator 44 attached to the boss 43 is slowly rotated. As the agitator 44 is rotated, the agitator 44 is provided on the spray pipe 31 through the hole 42 while unraveling the sprayed material such as organic fertilizer stored in the hopper 41.
As shown in FIG. 5, the toner is supplied to a receiving port 32 provided at a position apart from the swing shaft 26 which is the swing center.

Since the receiving port 32 is provided with a certain distance in the discharge direction of the material to be scattered from the swing shaft 26, that is, in the front end side, the object to be scattered in the receiving port 32 is already directional when the spray pipe 31 is rocked. ing. Therefore, the socket 32
The material to be sprayed supplied to has directivity in the discharge direction and is given energy in the discharge direction. Therefore, the material to be sprayed does not stay in the receiving port 32, and the spray tube 3
1 Spray from the tip.
