2. Description of the Related Art For example, charcoal made by burning rice husk or rice husk can contain a lot of water. When it is hot, water evaporates and the heat of evaporation causes the soil to become hot. It has a variety of benefits for fields, such as preventing overheating, absorbing water when it is cold, preventing frost from falling, and preventing insect pests.

[0003] Conventionally, for example, in the case where rice husks are sowed because of such an effect, the rice husks are temporarily piled up at several places in the field, and the workers sprinkle the rice husks with a scoop or the like. Although it is easy to disperse lightly, there is a problem that it is a troublesome operation that requires a lot of labor, and it is difficult to disperse evenly and uniformly. Even if you try to grind evenly with a hoki or rake, it does not work very well.

In addition, when the rice husk is scattered on the ridges of the field, extra work is troublesome because the scaffold between the ridges is narrow, and the husks may protrude from the ridges. There was also a problem that there was much waste.

The present invention has been made in view of the above-mentioned conventional problems and solves the problem. Based on a completely new idea, rice husk, charcoal, fertilizer, etc. are adjusted according to the distribution width such as the ridge width of a field. It is intended to provide an epoch-making dispersing device that can automatically and uniformly disperse.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention (how to implement the invention) will be briefly described with reference to the drawings, showing the operational effects thereof.

For example, when scattered materials 2 such as rice are scattered in a field, a towing storage body 3 storing the scattered materials 2 is connected to a mobile vehicle 1 such as a tractor, and the bottom of the towing storage body 3 is discharged. The exit portion 4 is opened to allow the mobile vehicle 1 to travel.

The scattered material 2 drops gradually from the discharge port 4 at the bottom of the running towing container 3 and passes through the reciprocating sieve 5 under the discharge port 4 to the field. The sieve is dropped.

That is, since the sieve body 5 reciprocates in the direction intersecting with the falling direction of the scattered material 2 by the sieving body vibration mechanism 6, the scattered material 2 dropped from the discharge port 4 is In addition, the scattered material 2 that has hit the sieve body 5 passes through the sieve body 5 while bouncing in the horizontal direction, and is dropped by a so-called sieve, so that the scattered material 2 is uniformly distributed with a uniform thickness in a predetermined range. It can be scattered.

The thickness of the scattered material 2 can be adjusted by adjusting the amount of drop of the scattered material 2 such as the moving speed of the vehicle 1, the opening degree of the discharge port 4, and the vibration speed of the sieve 5. Becomes That is, for example, to increase the moving speed,
Alternatively, if the opening degree of the discharge port portion 4 is narrowed, or if the vibration speed of the sieve body 5 is increased, it can be thinly scattered. In addition, the sifter dropping action of the sifter vibrating mechanism 6 of the sifter body 5 makes it possible to uniformly spread the scattered material 2 without performing a conventional leveling operation.

Further, an elastic body 10 is provided on the opposite side of the connecting body 9 provided on the sieve body 5, and the elastic body 10 absorbs a shock or the like due to vibration of the sieve body 5 and the sieve body 5 by the sieve vibration mechanism 6. And the noise caused by the reciprocating movement of the sieve body 5 is greatly reduced.

Further, if the discharge portion 28 is provided on at least one of the right and left sides of the sifting body 5 provided on the bottom of the towing storage body 3 with respect to the traveling direction of the moving vehicle 1,
Impurities 27 remaining on the sieve 5 can be discharged from the discharge portion 28 without passing through the sieve 5, and it is ensured that the spatter 2 and the impurities 27 are clogged on the sieve 5. In addition to this, if the moving vehicle 1 is run while discharging the scattered material 2 from the discharge portion 28, the scattered material 2 can be quickly and thickly and uniformly deposited.

[0023]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described with reference to the drawings.

In this embodiment, the towing storage body 3 is formed in a storage box shape so that a large amount of the scattered material 2 such as rice husk can be stored therein. It can be connected to a mobile vehicle 1 such as a tractor that can run with wheels in alignment with a scaffold in between, so that the scattered material 2 can be dropped and discharged onto the ridges 19 from the outlet 4 at the bottom of the towing container 3 while towing. It is configured as follows. Specifically, in the left-right direction of the towing storage body 3,
A plurality of outlets 4 having opening areas at intervals corresponding to the width of the ridge of a wide field are provided in the front-rear direction of the towing container 3, and the bottom of the towing container 3 which is not the outlet 4 has an inclined surface. Are provided.

As shown in FIGS. 3, 5, and 6, a shutter plate for opening and closing each outlet 4 is provided at each outlet 4.
The shutter 14 is installed and arranged in a horizontal state, and the shutter plate 14 is simultaneously operated by the opening / closing mechanism 12 to adjust the aperture.

More specifically, as shown in FIG.
An opening / closing mechanism 12 is provided by pivotally connecting a shutter plate 14 having a window conforming to the shape of the shutter plate 14 and a shutter plate operating rod 15 via a rotation shaft 16.
The shutter plate 14 can be moved back and forth in the direction of the arrow when the shutter plate operation lever 15 is rotated in the direction of the arrow, and the opening degree of the discharge port 4 is adjusted by operating the shutter plate operation rod 15. It is configured to be able to do.

Therefore, when the towing housing 3 is towed by the moving vehicle 1 such as a tractor, and the shutter plate 14 is moved by operating the opening / closing mechanism 12 at the place where the scattered material 2 is to be dropped and discharged, the towing housing 3 is moved. Each of the plurality of outlets 4 provided at the bottom of the three openings is opened at the same time, and the scattered material 2 is dropped and discharged from each of the opened outlets 4.

Further, since the opening degree of the discharge port portion 4 can be adjusted, it is possible to adjust the amount of the dispersed substance 2 dropped and discharged.

Further, since the slope-shaped projection 13 is provided at the bottom of the towing container 3 which is not the discharge port portion 4, it is possible to spread out the scattered material 2 without leaving it at the bottom of the towing container 3. In addition, by enabling the operation of the opening and closing mechanism 12 to be operated from the driver's seat of the mobile vehicle 1 such as a tractor, it is possible to easily and evenly spread the uniform easily, so that the previously troublesome sowing work can be performed. It can be done very easily.

In the present embodiment, a sieve 5 is provided below the outlet 4 and the sieve 5 is connected to the outlet 4.
The sifter vibration mechanism 6 reciprocates in a direction intersecting with the falling direction of the scattered material 2 falling from the sifter 2.

More specifically, the sieve body 5 is constituted by a mesh plate with a peripheral frame 22 having a width approximately equal to the width of the ridge 19 of the field, and the mesh interval of the sieve body 5 is such that the sieve falls. And the proper size. That is, the size of the scattered material 2 falling from the discharge port 4 is set to a size that does not cause a large amount of clogging of the scattered material 2 due to clogging. It is configured to be small enough to fall through a sieve. More specifically, the mesh spacing is too small for the scattered material 2 and the sieve 5
The mesh spacing is appropriately configured so that the meshes are not clogged or the mesh spacing is too large so that the scattered material 2 does not pass through the mesh to perform the sieving action.

It is to be noted that several sieves 5 having different mesh intervals are prepared for the sieves 5 in accordance with the size of the scattered material 2, and the sieves 5 can be exchanged so as to have an appropriate interval as necessary. May be configured.

The sieve body 5 is pivotally attached to a suspension body 21 pivotally attached to the bottom of both front and rear side surfaces of the towing storage body 3 and vertically suspended so as to be reciprocally movable in the horizontal direction. At both ends,
The base end 9A of the connecting body 9 is pivotally connected to each other, a ring-shaped ring portion 9B is provided at the distal end of the connecting body 9, and the ring 9B of the connecting body 9 is mounted around the eccentric portion 8 described later. The sieving body vibration mechanism 6 is configured so that the sieving body 5 reciprocates in a substantially horizontal direction in a hanging state by the eccentric movement of the rotating eccentric part 8.

In this embodiment, the driving source 17 for rotating the movable vehicle 1 such as a tractor is employed as the driving source 17 for rotating the rotary shaft 7, and the rotation of the driving source 17 is performed by the power transmission mechanism 18. Is transmitted to the rotating shaft portion 7.

Further, elastic members 10 are disposed at opposite ends of the connecting rod 9 pivotally attached to the sieve body 5.

In this embodiment, the elastic body 10 employs a coil spring. One end of the spring is attached to a peripheral frame 22 of the sieve body 5, and the other end of the elastic body 10 is attached to the towing housing 3. When the sieve body 5 is pulled by the eccentric cam 8 toward the connecting member 9 in the horizontal direction, the sieve body 5 is pulled in the reverse direction (return direction) and is urged to return. doing.

Accordingly, the dispersed matter 2 dropped and discharged from the discharge port 4 passes through the sieve body 5 provided at the lower part of the discharge port 4 and is sieved and dropped. At this time, as shown in FIG. 9, even if the amount of the scattered material 2 dropped and discharged from the discharge port portion 4 is somewhat uneven or the traveling speed is uneven, the mesh of the sieve body 5 is sieved. The amount of the scattered material 2 passing through is kept substantially constant, and the scattered material 2 hitting the sieve body 5 is sieved and dropped while rebounding in the horizontal direction. Spatter 2 can be scattered.

At this time, since the sieve body 5 is vibrating in the horizontal direction by the sieve body vibrating mechanism 6,
The sieve is less likely to be clogged in the mesh of the sieve body 5, the sieve action is reliably exerted, and the scattered material 2 can be uniformly scattered.

Further, since the reciprocating motion is constituted by the eccentric motion of the eccentric cam 8 which rotates the sieving body vibration mechanism 6, the reciprocating motion of the sieving body 5 can be ensured with an extremely simple and easy-to-manufacture configuration. become.

Since the elastic body 10 is provided on the opposite side of the connecting body 9 pivotally attached to the sieve body 5, the elastic body 10 pulls the sieve body 5 when moving the sieve body 5 to the elastic body 10 side. 5
The reciprocating motion of the sieve body 5 is made smooth, and the shock accompanying the reciprocating motion of the sieve body 5 is absorbed, so that the noise is greatly reduced. In addition, since the elastic members 10 are provided at two positions, the reciprocating movement of the sieve member 5 is stabilized without being offset.

The driving source 17 of the vibrating mechanism 6
Is provided on the mobile vehicle 1, there is no need to mount a drive source such as a heavy motor on the towing housing 3, and the rotation of the drive source 17 is transmitted to the eccentric cam 8 by the simple power transmission mechanism 18. It is possible to reduce the weight and to facilitate the production.

If the sieve 5 is prepared so that several sieves 5 having different mesh intervals are prepared in accordance with the size of the scattered material 2 and can be replaced as needed. Various scattered materials 2 such as rice husk, charcoal, and fertilizer can be scattered, which is extremely practical.

In this embodiment, as shown in FIGS. 3, 7, and 8, the spread width adjusting member 11 is a plate-like spread width adjusting plate 11.
At the lower part of the discharge port 4 and horizontally on the left and right sides in the moving direction of the traction storage body 3, respectively, and adjusts the distance between the two scatter width adjusting plates 11 so as to be locked. Is configured to be adjusted.

Accordingly, the ridge 19 having a narrow width as shown in FIG.
When the scattered material 2 is to be scattered, the interval between the two scattered width adjustment plates 11 is reduced so that the scattered width is adjusted to the width of the ridge 19, and the ridge 19 having a wide width as shown in FIG. When the scattered material 2 is to be scattered, the scattered width can be adjusted to the width of the ridge 19 by widening the interval between the two scattered width adjustment plates 11, and it is not necessary to scatter the scattered material 2. There is no waste of dispersing material 2 between 19 and ridge 19.

In the present embodiment, the scattering width adjusting plate 11 is provided between the discharge port 4 and the sieve body 5, but it may be provided below the sieve body 5, or as in the present embodiment. Without adjusting the scatter width at the interval between the two scatter width adjustment plates 11, only the one scatter width adjustment plate 11 can be moved and adjusted. The spread width may be adjusted at an interval with one end of the spread material. In short, the spread width adjusting plate 11 may be provided at any place as long as the spread width of the spread material 2 that is dropped and discharged can be adjusted. Good.

The tow housing 3 is a three-point link elevating device.
The three-point link elevating device 20 is connected to the rear of the moving vehicle 1 such as a tractor by the
(The three-point link elevating device 20 is generally provided in recent tractors, and therefore, a more detailed description is omitted.) .

FIGS. 10, 11, and 12 show a second embodiment of the scatter width adjusting body 11. FIG.

The spread width adjusting body 11 is a sheet, and is provided horizontally below the discharge port 4 on the left and right sides in the moving direction of the traction housing 3, respectively. By winding or unwinding the sheet-like dispersion width adjusting body 11 at intervals of 11, the degree of blocking of the sieve body 5 is adjusted and locked so that the dispersion width can be adjusted. I have.

The scatter width adjusting member 11 is provided with winding portions 24 for winding and unwinding the scatter width adjusting member 11 on the left and right outer edges, respectively. These are configured such that when one winding unit 24A is rotated by the chain rotation mechanism 25, the other winding unit 24B is chain-rotated.

The winding direction of the winding section 24A and the winding section 24B is opposite to each other. That is, with reference to FIG. 10, when one winding unit 24A is rotated in the direction of the arrow to wind the dispersion width adjusting body 11, the chain rotating mechanism 25 rotates the other winding unit 24B.
Also rotates in a chain in the direction of the arrow to wind up the dispersion width adjusting body 11.

The rotation of the winding section 24A is controlled by the rotation of the winding section 24.
The rotation operation is performed by a winding operation mechanism 33 provided at one end of the A.

The take-up operation mechanism 33 is composed of a rotating operation part 34 provided with a plurality of locking recesses 31 and a locking rod 32 which abuts and locks on the locking recess 31. Dynamic operation part 34

Further, the locking rod 32 is pulled by an elastic body such as a spring and constantly presses the locking recess 31, so that
When it is desired to rotate 34 in the other direction (in this embodiment, in the direction in which the dispersion width adjusting body 11 is rewound), the locking rod 32 is pulled to separate from the locking concave portion 31 and the rotation operating section is moved. Perform the rotation of 34 freely.

Further, a slack preventing elastic body 26 is provided at the tip of the scattering width adjusting body 11.

By being pulled by 26, the scatter width adjusting body 11 is configured so as not to be slackened in a stretched state.

Therefore, in the second embodiment, the sheet width of the spread width adjusting member 11 is wound around the winding section 24 or unwinded to adjust the spread width. By simply rotating, the spread width can be adjusted to the width of the ridge 19 very easily as compared with the case where the above-mentioned plate-shaped spread width adjusting plate 11 is used.

That is, in the case of using the plate-like spread width adjusting plate 11, the spread width must be adjusted by pushing or pulling the spread width adjusting plate 11 by hand one by one. The spread width adjustment plate 11 must be fixed with bolts or the like so as not to be displaced by the vibration, which is cumbersome and difficult to finely adjust, and the range that can be adjusted with one type of spread width adjustment plate 11 is narrow. Therefore, when it is necessary to perform a wide range of adjustment, it is necessary to prepare dispersion width adjustment plates 11 having different lengths, whereas the sheet-like dispersion width adjustment body 11 of the second embodiment is required. Can be adjusted simply by rotating the winding unit 24, and the unnecessary scattering width adjustment plate 11 can be wound around the winding unit 24, so the adjustment range is wide, and it can be adjusted smoothly in any range It is possible and fine adjustment is easy.

Further, in the second embodiment, since the pair of left and right scatter width adjusting plates 11 is configured to be wound or unrolled in conjunction with the chain rotating mechanism 25, the scatter width adjuster 11 of one of the scatter width adjusters 11 is used. The spread width can be adjusted extremely easily and smoothly only by rotating the winding unit 24.

Further, the scattering width adjusting plate 11 is
Therefore, when the spreading width adjusting plate 11 is unwound from the winding unit 24 to reduce the spreading width, the spreading width adjusting plate 11 can be smoothly adjusted without being loosened. .

Further, since a ratchet-type winding operation mechanism 33 for rotating the winding section 24 is provided, if the scattering width is adjusted to a predetermined value, the scattering width adjusting body 11 is automatically adjusted due to vibration during operation. The spread width does not change due to a shift in the position, and the practicability is extremely excellent.
