Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method of stacking pre-dried grass in a donut shape, applying forced ventilation to reduce moisture appropriately, storing it as it is, and taking out the required amount when needed to feed cattle. Related to Shida Haytower, etc.

Traditionally, so-called feed silos have been used to store grass, but in these feed silos, the grass is almost sealed by the walls and roof of the silo, and ventilation must be controlled throughout the entire culm. The grass may rot;
Further, due to the closed condition, CO2 may accumulate and cause a suffocation accident, and furthermore, the entire device is bulky and expensive.

The present invention has been made in view of these conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

Fig. 1 shows the overall structure of the Hay Tower. Reference numeral 1 denotes a roof body consisting of a substantially conical top part 1A and a cylindrical body part 1B, and an opening part 1C is provided in the center of the top part 1A. A distributor 2 is placed there.

This distributor 2 has an upper fixed part 2A connected to the chute 3, an opening part 2C opening laterally, and a rotating part 2B which is rotationally driven via a motor 4 and a reducer 5. We are prepared.

Several traction rods 6 are fixed in the horizontal direction to this rotating portion 2B, and a central support rod 1 is suspended.

The center support rod γ is held by the rotation portion 2B via a bearing (not shown) so that the center support rod 7 and the rotation portion 2B can freely rotate relative to each other.

Further, as is clear from FIG. 2, an annular support ring 9 is suspended from the traction rod 6 via a wire 8, and a plurality of non-illustrated uniforms are connected via this support ring 9 and wire 10. Either a flat rake (for leveling) or an unload rake 11 (for taking out) can be selectively attached.

Each unload rake 11 has a large number of scraping claws 1 on its periphery.
An unloading pawl wheel 11b provided with an unloading claw wheel 1a is rotatably attached to a plurality of shaft portions 11d provided on a gang 11c.

Further, a polygonal (eg, hexagonal) plug 12 is attached to the central support rod γ so as to be movable up and down.

As shown in FIG. 4, the plug 12 is installed with a rack 13 on the central support rod 7 side, a pinion 14 and a drive motor 15 for rotating it on the plug 12 side, and the pinion 14 is mounted on the rack. 13, and the rotation of the pinion 14 causes the plug 12 to move vertically along the central support rod γ.

In FIG. 4, reference numeral 16 denotes a power supply cord for the motor 15, which is wound into a coil and placed inside the central support rod γ, and the lower end of this cord 16 is formed in the support rod 7 in its length direction. It extends outward from the elongated hole 11 and is connected to the motor 15.

Incidentally, FIG. 4 shows a state in which the plug 12 has been raised along the central support rod 1 to the upper limit position.

As shown in FIG. 1 and further in FIG. 5, a large number of skirt plates 18A are arranged adjacent to each other around the lower end of the cylindrical throat part IB constituting the roof body 1. The upper end of each skirt plate 18A is pivotally attached to the lower end of the body 1B, and the skirt plate 18A is swingably suspended.

Each skirt plate 18A has a large number of ventilation holes 19, as shown in FIG. 20, a protruding edge 20 of one skirt plate 18A,
Projection edge 20 of the other skirt plate 18A adjacent to this
The skirt portion 1
Skirt plates 18A forming part B can be held in a closed position.

As mentioned above, there is a disk I-'J computer 2 inside the roof body 1.
, the motor 4 that drives the rotating part 2B, the reducer 5, the traction rod 6, the annular support ring 9, the plug 12, the unloading rake 11 (my father was a leveling rake), etc. are held on this roof. The 11 bodies are suspended from the top of the resting area by wires 25 respectively attached to three pillars 24 erected around the body.

In particular, as is clear from FIG. 3, the tops of the three pillars 24 are connected and fixed to each other by connecting rods 26.

Further, each support column 24 is made of H-shaped steel, and is equipped with a manual or electric winch 21 at its lower part, and by operating each winch 21, the roof body 1 is raised and lowered via each wire 25. I have to.

In FIG. 5, the roof 1 shown by solid lines is shown being pulled up, and the roof 1 shown by phantom lines is shown being lowered.

As shown in FIG.
8 is installed.

Reference numeral 29 indicates a hollow base (see Fig. 1), and an opening 33 is provided approximately at the center of the base 29, and large and small bamboo screens are provided at predetermined locations around the opening 33. A ventilation section 30, 3L 32 consisting of the following is arranged, and FIG. 7 shows the arrangement of the ventilation section 30, 31.32 in a plan view.

The central opening 33 of the base 29 is located directly below the plug 12 supported at the center of the roof 1 and has approximately the same diameter as the plug.

34 is a dryer, and 35 is a fan, which are arranged in a casing 36 that communicates with the inside of the base 29 so as to supply dry hot air at an appropriate temperature into the base 29.

Thus, the dry hot air supplied into the base 29 is
It is forcibly led out above the base through the central opening 33 and ventilation parts 30, 31 and 32.

3γ is a conveyor that loads the grass scraped off by the unloading rake 11 and transports it from inside the base 29 to the cowshed 38 outside; A blower for feeding to the distributor 2 is shown.

The casing 36 and the conveyor 3γ are arranged on a straight line passing through the center of the base 29, as shown in FIGS. 1 to 3, and more specifically in FIG.
The direction of flow of the drying air supplied into the base 29 from the dryer 34 in the dryer 6 and the direction in which the conveyor 31 carries out the grass are formed in the same direction.

FIG. 8 shows in detail the arrangement and mounting state of the unloading rake 11, in which each gang 11c is equipped with a plurality of unloading pawl wheels 11b (for example, six), respectively. ... is the cross-sectional shape of the drop opening (described later).
It is arranged in the tangential direction of a polygon (which is actually a polygon but is assumed to be a circle) and is fixedly attached to the support ring 9.

The 18 pawl wheels llb attached to the three gangs 11c are arranged radially so that the orbits of the respective pawl wheels do not overlap each other when the gang 11c rotates. They are installed at slightly different positions.

(See Figure 8) Next, to explain the operation of the Haytower constructed as described above, first, lower the roof body 1, lower the skirt portion 18 to near the upper surface of the base 29, and then lower the skirt portion 1.
As shown in FIG. 6, the skirt plates 18A constituting 8 are connected to each other with bolts and nuts and kept in a closed state, while the plug 12 is also lowered to a position below the central support rod 1. Each wire 10 attached to the traction rod 6 and the support ring 9 suspended from the traction rod 6 by a wire 8 are provided with a leveling rake (not shown) for evenly depositing grass.
Install.

Then, the grass, which has been dried in advance and cut into appropriate lengths, is passed through the chute 3 by the blower 39 and delivered to the roof body 1.
The feed is fed to the distributor 2 at the center of the top, and the rotary part 2B of the distributor 2 is rotated to drop the grass onto the base 29 surrounded by the skirt part 18, so that a donut-shaped pile of grass is deposited around the plug 12. continue to form.

Once the deposited layer has been formed to some extent, the dryer 34 and fan 35 are started to supply dry hot air into the base 29.

The supplied dry hot air flows through the ventilation section 3 as shown by the arrow in Figure 1.
0 to 32 and rises through the central opening 33 to forcefully dry the deposited layer.

Incidentally, as the rotating section 2B of the disk I-IJ computer 2 operates, the traction rod 6 integrated with the rotating section 2B also rotates, thereby causing a leveling rake (not shown) to spread and deposit the grass uniformly.

When the height of the grass pile layer 40A formed in this way reaches near the upper end surface of the plug 12, the blower 39 is stopped to interrupt the grass supply and the rotation of the rotating part 2B of the distributor 2 is stopped. Then, the winch 21 provided on each support column 24 is operated to raise the roof body 1 to a predetermined height.

As the roof body 1 rises, the plug 12 is also pulled upward, thereby forming a drop opening 41 in the center of the grass pile layer 40A.

Thereafter, the blower 39 is operated again to start feeding grass, and at the same time, the rotating part 2B of the distributor 2 is rotated to form a new grass pile layer 40B on the already formed pile layer 40A. .

Thereafter, similar operations were repeated several times to complete the formation of grass pile layers 40A, 40B, 40C, etc. of appropriate heights,
Store it as is.

During the formation of the deposited layers 40A, 40B, . . . , forced drying is continuously performed using a dryer 34.

When taking out grass from this hay tower, as shown in FIG. 1, the leveling rake is removed, the unloading rake 11 is attached, and the plug 12 is moved from the imaginary line in the figure to the position shown by the solid line. It is in a state where it is raised up to a point where it is pulled out upward from the drop opening 41.

Then, the motor 4 is operated to rotate the traction rod 6 and the unloading rake 11, whereby the grass is gradually scraped off from the upper layer, passing from the central droplet 41 to the opening 33 and the hopper 42 to the conveyor 3γ. The cows fall to the top and are conveyed to the cow shed 38 by this conveyor 3γ.

At this time, if the dryer 34 and fan 35 are operated, a part of the grass that falls onto the conveyor 3γ via the hopper 42 will be carried by the drying wind flowing in the grass conveying direction of the conveyor 31 to the cowshed 38. In addition to being conveyed sideways in an auxiliary manner, any clumps of grass falling from the hopper 42 can be broken up.

When the grass is scraped off in this way and the upper surface of the accumulated layer is lowered to near the lower end of the skirt portion 18, when the grass is to be removed continuously, the skirt plate 18A constituting the skirt portion 18... After uncoupling them so that they can open outward, each winch 2
The roof body 1 is lowered by operating γ, and the same work of scraping off the pasture tracks as described above is performed.

Note that at least a portion of the chute 3 is made of a flexible material so that it can follow the rise and fall of the roof body 1.

The present invention has the above-mentioned configuration, and when stacking or taking out grass, the roof body can be raised and lowered appropriately according to the height of the grass pile, and unlike conventional feed silos, the grass pile is in a sealed state. Since it is constantly exposed to the outside air, it is less likely to rot, and therefore only requires a simple means of blowing drying air.

In addition, a drying mode is provided in which drying air is supplied from the central opening of the base to the central falling opening of the donut-shaped grass pile (2) and is led out in the radial direction of the grass pile, and around the central opening. Since the drying method is combined with a drying method that directs drying air to the lower part of the donut-shaped grass pile layer from the ventilation part of the dryer, the grass pile layer can be dried evenly, and in particular, the grass at the bottom of the pile layer can be dried effectively. Ru.

In other words, it is difficult for the drying air from the central fallout of the grass pile layer to reach the grass on the base, and in addition, the grass in this area is piled up first and taken out last, so the storage time is short. is the longest and is under the worst drying conditions, but by supplying drying air to the lower part of the grass pile layer, the grass in this area can be dried well.

Another advantage is that there is no risk of suffocation because the situation is not airtight.Furthermore, in the present invention, when removing grass from the hay tower, the blowing means is activated and the grass is moved from the opening of the base onto the carrying means. A portion of the falling grass can be pneumatically blown toward the grass transport direction of the transport means, which not only improves transport efficiency but also loosens the grass that falls in clusters from the opening of the base. Furthermore, this opening can be expected to have the advantage of being prevented from being clogged with grass.
