Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a device for preventing the bridging phenomenon of fertilizer in a fertilizer applicator in which a feeding member is attached to the entire bottom of the hopper.

(b) Prior Art A technique in which a single partition plate is suspended inside a hopper is known.

For example, there is a technique described in Japanese Utility Model Publication No. 48-35698.

(c) Problems to be solved by the invention However, in the above-mentioned conventional technology, the partition plate is
Along with the feeding device inside the hopper, only one sheet is installed above the center of the feeding device, so the conditions for the left and right fertilizers are the same, and both fertilizers in the space divided into two are directed towards the feeding device. When it tries to descend, it still ends up forming a bridge.

Therefore, in the above-mentioned prior art, the bridge state is broken by driving and forcibly swinging the one partition plate.

The present invention eliminates the occurrence of crosslinking within the hopper without forcibly driving the partition plates.

In other words, two smooth partition plates are suspended inside the hopper so that they can swing freely, and the partition plates divide the space inside the hopper into a central area corresponding to the feeding member and both side areas. The structure is such that only one part of the fertilizer is fed out, and when this is almost exhausted, one of the partition plates is tilted to feed out one of the fertilizers, and when this is almost exhausted, the other partition plate is tilted and the remaining fertilizer is fed out. The structure is such that cross-linking of the fertilizer can be more reliably prevented and the entire fertilizer can be delivered smoothly.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

Both side plates 15, 15 of the hopper 14 are inclined in a downward drawing shape to narrow the bottom surface, and on the bottom surface of the hopper,
In a fertilizer applicator in which a delivery belt 24 for delivering fertilizer in the direction along the side plates 15, 15 is arranged and a fertilizer outlet 20 is provided at the conveying end of the delivery belt 24, the width end position of the delivery belt 24 is located inside the hopper. Two partition plates 35 and 36 are suspended above so that their lower ends can swing freely, and the partition plates 35 and 36 allow the hopper 1 to be
4 is divided into a central space A above the feeding belt 24 and spaces B and C on both sides.

(E) Embodiment The purpose and structure of the present invention are as described above. Next, the structure of the embodiment shown in the attached drawings will be explained.

In the embodiments shown in FIGS. 1, 2, and 3, 1 is a rectangular underframe, and four rectangular beams are assembled into a frame with welded joints, and an axle 2 is supported at the center of both side beams. Wheels 3, 3 are attached to both ends of the frame, and protrusions 5, 5 and opposing protrusions 6, 6 are welded to both leg ends and the upper edge of an inverted U-shaped hitch frame 4 welded to the front crosspiece, respectively.

This hitch frame connects the protruding pieces 5, 5 at both leg ends to the two lower links coming out of the tractor, inserts the upper link between the protruding pieces 6, 6 on the upper edge, and connects them to a three-point link. The underframe 1 is connected to a tractor by a hitch frame 4 to be towed.

Numeral 7 is a groove claw having a V-shaped cross section, and its suspension rod 8 is inserted into a tube metal 9 welded to the center of the front crosspiece of the underframe 1 and fixed in an adjustable manner. Reference numerals 10 and 10 denote two stacking plates, which are attached to the front ends of both side crosspieces of the underframe 1, bent inward, and inclined in the shape of a lower drawing at the center to approach the rear upper corner of the groove-making claw 7.

Reference numerals 11 and 11 designate two soil cover plates made in the shape of a shallow bowl and rotatably supported on the suspension rod 12, and the tube metal 13 welded to both sides of the rear crosspiece of the underframe 1. The two soil covering plates 11, 11 are arranged in a figure-eight shape with the rear side narrowed.

14 is a square hopper, left and right side plates 15,
15 is tilted in the shape of a lower drawer so that the bottom is about 1/3 of the upper opening.
Attach two supporting pieces 17, 17 rising from both side beams of the underframe 1 to both side plates 15, 15,
A stay 18 coming out from the front plate 16 is connected to the upper edge of the hitch frame 4. 20 is the fertilizer outlet of Hopper 14,
A large rectangular hole is cut out at the bottom of the front plate 16 to form the lid plate 2.
1 and passed through the long hole 22 of the cover plate 23
is screwed onto a nut on the inner surface of the front plate, and the fertilizer outlet 20 is closed or its opening degree is adjusted using this cover plate.

Reference numeral 24 denotes a feed belt, which is installed in the front and back direction completely on the lower draw-shaped bottom of the hopper 1, hooked on the front and rear pulleys 25 and 26 that are supported on both sides of the underframe 1, and protrudes to the front and rear of the hopper. A chain 30 is applied to the chain ring 28 attached to the pulley shaft 27 and the chain ring 29 on the axle, and the feeding belt 24 is advanced in the counterclockwise direction of the arrow using the wheels 3, 3 as a driving source.

Reference numeral 31 denotes an impeller, which is made to have the same width as the feed belt 24 and installed near the fertilizer outlet 20 of the hopper.A chain 34 is hung on a chain ring 32 on the core shaft and a chain ring 33 attached to the front pulley shaft 27. The impeller 31 is rotated by the conduction member to agitate the fertilizer near the outlet.

The above configuration is almost the same as that of a known fertilizer spreader in which both side plates of the hopper are inclined in the shape of a lower drawer and a feeding belt is attached to the bottom of the hopper, and when the underframe 1 is towed by a tractor, the wheels 3, 3 Along with this, the feed belt 24 advances and feeds out the fertilizer in the hopper from the fertilizer outlet 20. The impeller 31 rotates and stirs the fertilizer near the outlet, and the fertilizer is transferred to the feed belt 2.
After falling from the front edge of 4 and being collected by the collecting plates 10, 10, it enters the groove cut by the groove-making claw 7,
After that, the soil covering plates 11, 11 advance and cover with soil.

In this delivery belt type fertilizer applicator, the delivery belt 24 transports the fertilizer placed on it, and since the impeller 31 of the same width rotates near the outlet, only the fertilizer in the center corresponding to the delivery belt 24 is delivered. Fertilizer on both sides tends to remain in the hopper,
The entire amount cannot be dispensed unless the side plates 15, 15 are occasionally struck to break up the fertilizer.

In this embodiment, two partition plates 3 are installed inside the hopper 1.
5 and 36 are hung freely to swing freely, and the space inside the hopper 4 is divided into a central portion A corresponding to the feed belt 24 and side portions B and C.

The partition plates 35 and 36 are made of synthetic resin, a steel plate coated with synthetic resin, or stainless steel, and have smooth surfaces. The lower front corner 37 is cut into a rectangular shape to avoid interference with the impeller 31.

The partition plates 35 and 36 are made by fixing short pins 40 and 40 at both ends of a long and thin strip 38 attached to the upper edge, and inserting these pins into small holes made in the front and rear plates of the hopper 1 to swing them. Hanging freely, 2 partition plates 35,
36 at intervals approximately equal to the width of the feed belt 24.

The fertilizer hopper 14 is also made of synthetic resin, a steel plate coated with synthetic resin, or stainless steel, and has a smooth inner surface, like the partition plate.

(f) Effects of the invention One embodiment of the invention has the above-mentioned configuration, and its effects will be explained in the order of FIGS. 1 to 7.

As shown in Figure 1, the hopper 14 is fully loaded with fertilizer.

Next, as shown in FIG. 2, when this hopper is towed by a tractor and the delivery belt 24 advances, the fertilizer in the central portion A placed on the delivery belt is delivered.

Next, as shown in Figure 3, the fertilizer in the center area A is placed on the partition plate 3.
5 and 36, and since the partition plate is smooth, this fertilizer slides down the plate surface, and is successively delivered to the delivery belt 24 to be reduced.

Next, as shown in Figure 4, when the fertilizer in the center part A is almost gone, either the left or right partition plate, for example, the right partition plate 35, is pushed by the fertilizer in the right part B and tilts to the left.
This partition plate is almost parallel to the right side plate of the hopper.

Next, in FIG. 5, due to the leftward inclination of the partition plate 35, the fertilizer on the right side B is placed on the feeding belt 24, so the fertilizer on the right side is fed out, and this fertilizer is transferred between the smooth partition plate 35 and the inner surface of the hopper 14. They slide down and are successively delivered to the delivery belt 24 and reduced in size.

Next, as shown in Figure 6, when the fertilizer on the right side B is almost gone, the left partition plate 36 is pushed by the fertilizer on the left side C and tilts to the right, and this partition plate becomes almost parallel to the left side plate of the hopper, and at the same time The right partition plate 35 also moves to the right side.

Next, as shown in Fig. 7, due to the inclination of the partition plate 36 to the right, the fertilizer on the left side C is placed on the feeding belt 24, so the fertilizer on the left side is fed out, and this fertilizer is transferred between the smooth partition plate 36 and the inner surface of the hopper 14. They slide down and are successively delivered to the delivery belt 24 and reduced in size.

The present invention can also be applied to a fertilizer applicator equipped with a compost hopper. That is, in the present invention, a smooth partition plate is suspended inside the hopper so as to be able to swing freely, and the space inside the hopper is divided by this partition plate, so that the fertilizer can slide down the smooth plate surface in each section. Since the partition plate swings due to the unevenness of the ground, the entire amount of fertilizer in the hopper is smoothly delivered without any bridging.

(g) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, in a fertilizer applicator in which both side plates of the hopper are tilted in a downward drawing shape to narrow the bottom surface, and the feeding member is mounted completely on the bottom surface, two smooth partition plates are installed inside the hopper so that they can swing freely. Since the space inside the hanging hopper is divided into a central space A corresponding to the feeding member and spaces B and C on both sides, the fertilizer in the central space A located above the feeding belt 24 is most likely to be fed out by the feeding belt 24. Initially, only a portion of this central space A is delivered to the delivery belt 24.

Since the fertilizer is straight with the central space A and has no constricted portion, there is no possibility of formation of bridges when the fertilizer descends, so that it can be fed out smoothly.

While the fertilizer in the central space A is fed out, the fertilizer in the left and right spaces B and C is fixed by pressing the partition plates 35 and 36 by the fertilizer in the central space A. The amount of fertilizer hardly drops.

When the fertilizer in the central space A finishes being delivered by the delivery belt 24, the partition plates 35 and 36 become swingable, and the fertilizer in the spaces B and C on both sides can freely move to the central space A. In the end, no bridging occurs, and the fertilizer in the central space A and both side spaces B and C can be smoothly fed out.

Secondly, the space inside the hopper is divided by smooth partition plates that are free to swing and are not forced to move, and the fertilizer slides down the surface of these plates and the partition plates swing freely. In addition to ordinary fertilizers, even highly entangled compost can be smoothly fed out in its entirety without causing crosslinking.

Thirdly, the partition plate is not forcibly driven as in the prior art, but simply hung, so the structure is simple, and it is extremely useful for a fertilizer applicator in which a feeding member is mounted on the entire bottom surface.
