(Points of interest)
Can rice husks generated after harvesting rice be crushed or crushed because they are blown away by the wind without proper treatment and are adversely affected by the surrounding environment? In general, after pre-treatment such as incineration or steaming and burning to charcoal, it was generally carried out as a compost and then used as compost. In addition, there is a problem that labor and costs such as introduction of machines and assignment of workers increase, and smoke and dust generated during incineration and steaming use houses, factories and roads close to the countryside. There is a problem such as causing a great deal of trouble to pedestrians, vehicles, etc., and recently, there is a tendency to avoid such processing.

(Conventional technology)
Under these circumstances, in recent years, rice husks after threshing are sprayed on the field as they are, and then crushed into the soil and reduced to the ground, leading to soil improvement due to the properties of the rice husk and its unique shell structure At the same time, the fact that the effect of fertilization with compost and other organic fertilizers can be enhanced gradually became clear, so how to uniformly and efficiently spread rice husks discharged from rice hullers on the field The applicant of the present application paying attention to such a situation has succeeded in developing and commercializing the “rice husk spraying device” invention already disclosed in Patent Document 1 (1). ing.

    This rice husk spraying apparatus that has already been developed includes a tractor or the like as shown in the side view of the rice husk spraying apparatus during the spraying operation in FIG. 9 and the side view of the conventional rice husk spraying apparatus in cross section in FIG. The container portion 5 is supported by the skeleton body 10 that can be connected to the mounting mechanism 80 of the traveling vehicle 8, and the front and rear delivery walls 24 and 27 are formed in the lower portion thereof, and the spray port 21 is provided below the one delivery wall 24. In addition to forming the opened hopper portion 2, an obstructing member 29 is horizontally mounted on the upper portion parallel to the spraying port 21, and an opening / closing shutter 43 is incorporated in the spraying port 21. A large amount of rice husk 9 accommodated in a piled state is loaded with the total weight concentrated toward the hopper 2 as indicated by the large white arrow B in FIG. 9 When starting spraying In contrast to this load direction (outlined large arrow B), the open / close shutter 43 must be slid and opened as shown by the outlined small arrow C in FIG. In addition, the friction force generated when the opening / closing shutter 43 is slid open causes the rice husks 9 around the opening / closing shutter 43 and the rice bran or mixed rice straw twigs to be in mesh with each other, Even after the opening / closing shutter 43 is opened, the meshing state is maintained and it is easy to fall into a state where it cannot be sprayed.

In order to solve such obstacles due to the opening / closing shutter 43, for example, as shown in Patent Document 1 (2), a rear column and a rear surface are arranged at the rear end of a flat rectangular base that can be placed on a cargo bed of a freight vehicle. A rear surface portion to which the horizontal frame is fixed is erected, and a bottom plate that can be raised and lowered with the lower portion of the rear surface portion as a fulcrum is arranged on the base, and the front column, the front horizontal frame, and the lateral frame on both sides are arranged on the bottom plate. On the same base plate, the rear bag, the rear horizontal frame, the front column, the front horizontal frame, the front horizontal frame, and the harvesting bag suspended on both side horizontal frames are placed on the bottom plate, and the base An air bag is interposed between the bottom plates, and exhaust gas from a freight vehicle engine is sent into the air bag to be inflated, and the bottom plate is inclined so that its front end rises. Etc. that can be forcibly discharged, and in Patent Document 1 (3) Similarly, two front and rear rice seeding openings are opened at the bottom of a rectangular parallelepiped housing frame that can store rice husks, and each rice seeding opening can be opened downward with the front ends of those rice seeding openings as fulcrums. An open / close plate is provided, and the open / close plate before and after the total weight of the rice husks stored in a stack in the storage frame is opened and operated in the direction in which the total weight of the rice husks is added. There are some things that are made possible.

(Awareness of problems)
As described above, various types of spraying devices that have been proposed in the past as represented by the above-mentioned Patent Document 1 and that accommodate granular materials, powdery materials, etc. in a piled state and allow the bottom to be discharged or sprayed. May cause various problems such as complicated structure, lower durability, and high price, and bridging phenomenon in which the rice husks stored in a stack in the storage frame mesh with each other on the opening and closing plate. There is a defect that spraying stops after the opening and closing plate opens, and a special part for scraping must be added, such as providing a chaff scraping member linked to the opening operation of the opening and closing plate. In spite of the continuous increase in the number of points and the accompanying increase in the opening / closing resistance of the opening / closing plate, there are concerns about a decrease in opening / closing operability, etc. On-site I could not deny the resentment that has been devoid of fine consideration on the definitive mechanism.

(Object of invention)
Therefore, the present invention can prevent the trouble of stopping the discharge due to the meshing of the rice husks stored in the container portion in a piled state, and the new rice husk that can easily perform the opening operation of the spraying port. Judging whether it is impossible to develop a spraying technique, we started development and research very quickly, and as a result of repeating trial and error over a long period of time and many trials and experiments, this time finally a rice husk with a new structure The present invention has succeeded in realizing the spraying device, and the configuration thereof will be described in detail below together with an embodiment representing the present invention shown in the drawings.

(Structure of the invention)
As clearly understood from the embodiments representing the present invention shown in the drawings, the rice husk spraying apparatus of the present invention basically includes the following configuration.
That is, it has a skeleton body that can be connected to or mounted on a tractor or other traveling vehicle, and a container portion that is supported by the skeleton body and that can accommodate a predetermined amount of rice husk. A spraying port that opens continuously below the peripheral wall is opened, and an opening / closing lid that can be freely opened and closed is provided at the spraying port. The sprinkler is pivotally attached via a support mechanism, and the rotating end opposite to the base end faces either one of the front and rear edges of the spraying port where the horizontal support mechanism is located. It is mounted so that it can be closed by contacting either the front or rear edge of the mouth, and the top / bottom position of the opening / closing lid in the closed state is not set to the horizontal position, but slightly descends from the base end to the rotation end. Opening / closing operation that can be operated from the appropriate position outside the skeleton body to the appropriate position of the open / close lid after being installed in an inclined arrangement so as to have a gradient. A structure in which a mechanism is incorporated and the rice husk accommodated on the top surface of the opening / closing lid in a closed posture is energized with a force that flows in a downward slope in advance from the stage before the opening of the opening / closing lid. The rice husk spraying device.

    When the rice husk spraying device having this basic configuration is shown as a more concrete one, a skeleton body that can be connected to or mounted on a tractor or other traveling vehicle, and supported by the skeleton body, a predetermined amount of rice husk can be accommodated. The skeleton body is continuous with the front wall and lower rear wall of the container part, and the opening area is gradually reduced toward the spraying port that opens in a single left and right character shape. A funnel-shaped hopper portion is formed by the inclined front and rear delivery walls and a vertical wall concealing the left and right delivery walls left and right of the container portion, and the hopper portion spray port includes the same spray port. The open / close lid of the left and right single-letter shape that can be freely opened and closed has its proximal end pivotally attached to either the front delivery wall or the rear delivery wall via a horizontal shaft support mechanism at an appropriate position. The opposite end of the rotary is the same Attached so as to be able to be closed by abutting against the spraying port edge of the wrinkle facing either one of the front sending wall or the rear sending wall where the flat shaft support mechanism is located, It is not set in a horizontal position, but it is set to have a slight downward slope from its base end to the rotation end, and an opening / closing operation mechanism that can be operated from an appropriate position outside the skeleton body is incorporated in an appropriate position of the opening / closing lid The rice husk spraying device having the structure as described above is obtained.

    In other words, the skeleton body includes a skeleton body that can be connected to or mounted on a tractor or other traveling vehicle, and a container portion that is supported by the skeleton body and can accommodate a predetermined amount of rice husk. Open two or more spraying ports which are continuous in the lower part of the peripheral wall of the container part, and each spraying port has an opening / closing lid capable of opening and closing each spraying port. Each sprinkling end opposite to each base end is pivotally attached to one of the front and rear edges of the spout opening via a horizontal shaft support mechanism. Although it is facing either one of the front and rear edges of the mouth, it is attached so that it can be closed by contacting either one of the front and rear edges of each spraying mouth, and the top and bottom positions of each open / closed lid are in a horizontal position. Instead of tilting them so that they have a slight downward slope from their base ends to their pivot ends. And an interlocking mechanism that can be linked to the appropriate position of each open / close lid to match each other's open / close posture, and at least one of the interlock mechanism or each open / close lid is operated from the appropriate position outside the skeleton body A rice husk that incorporates a possible opening / closing operation mechanism and urges the rice husk accommodated on each top and bottom of the opening / closing lid in a closed position in advance from the stage before each opening / closing lid is opened. It becomes a spraying device.

    The rice husk spraying device of the present invention includes a skeleton body that can be connected to or mounted on a tractor or other traveling vehicle, and a container portion that is supported by the skeleton body and can accommodate a predetermined amount of rice husk. The skeleton body is formed by arranging two or more upper end openings in the shape of a plane rectangle in the front and rear, and each from the respective upper end openings toward each spray port that opens in a single left and right shape corresponding to the respective right and left respectively. A funnel-shaped hopper portion is formed by the front and rear delivery walls inclined so as to reduce the opening area of the front and the vertical walls concealing the left and right front and rear delivery walls, and the front end arrangement of the skeleton body is arranged in each hopper portion. The front delivery wall of the object is continuous below the front wall of the container part, the rear delivery wall of the skeleton body is arranged below the rear wall of the container part, and the left and right vertical walls are connected to the left and right of the container part. Continuing below the wall In addition, each hopper section spray port has a left and right single-letter-shaped open / close lid that can be opened and closed freely, and its base end is positioned in a horizontal axis at either the front or rear delivery wall. The rotary end opposite to the base end is pivotally attached via the support mechanism, and the opposite end of the horizontal support mechanism is opposed to either the front delivery wall or the rear delivery wall. Attaching to the spray mouth edge so that it can be closed, the top / bottom position of the open / close lid in the closed state is not a horizontal position, but a slight downward slope from the base end to the rotation end In addition to the setting, an interlocking mechanism that can be linked to the appropriate position of each opening / closing lid so as to match each other's opening / closing posture, and an opening / closing operation mechanism that can be operated from an appropriate position outside the skeleton body are incorporated in the appropriate position of the interlocking mechanism. A rice husk spraying device is included.

    As described above, according to the rice husk spraying apparatus of the present invention, unlike the conventional one, the spraying port is opened so as to continue to the skeleton body below the peripheral wall of the container part from the unique characteristic configuration as described above. The base end of the opening / closing lid is pivotally attached to either one of the front and rear edges of the spraying port via a horizontal shaft support mechanism, and the top / bottom position of the opening / closing lid is rotated from the base end when the spraying port is closed. An opening / closing operation mechanism that is installed in an inclined arrangement so as to have a slight downward slope toward the end, and that can open the opening / closing lid downward with low resistance and lightness, which is the load direction of the rice husk accommodated in the container part. In addition to greatly reducing the operation input, the rice husk accommodated on the top surface of the open / close lid in the closed position is pre-biased with a force that flows downward in the downward gradient direction from the stage before the open / close lid is opened. The opening and closing lid is open Occasionally, the speed of rice husk release is accelerated to prevent the trouble that the rice husks housed in a stack in a conventional manner mesh together and stop discharging. An excellent feature is that stable and smooth rice husk discharge can be realized.

    In addition, the hopper part formed between the lower part of the peripheral wall of the container part and the spraying port of the skeleton allows the spraying port and the opening / closing lid to be miniaturized, and the load of the rice husk applied to the top surface of the opening / closing lid is reduced. The opening / closing operation force of the opening / closing operation mechanism can be greatly reduced in each stage, and the opening / closing operation mechanism can be made smaller and lighter, making it possible to reduce the weight of the rice husk spraying device as a whole. The one with two or more spraying openings that open in front and rear of the skeleton body in the form of one letter on the left and right is more than the one with only one spraying opening, and the spraying opening, the lid and the opening and closing mechanism It can be downsized and can be opened and closed with a lighter operating force, enabling extremely uniform and efficient spraying of rice husks immediately after the opening of each opening and closing lid. Also formed hopper , For distribution opening and closing cover and opening and closing mechanism, and that is an effect that it is possible to achieve the and mitigation of further downsizing and operating force.

    And a rice husk spraying device having an interlocking mechanism that enables linkage so that the opening / closing postures of the plurality of opening / closing lids coincide with each other, and each upper end of each of the straws raised so as to reach the inside of the container part from the appropriate place on the top / bottom surface of each opening / closing lid In the meantime, the stirring rods are horizontally mounted and connected so that the corresponding portions are pivotally attached to form a link mechanism, and the opening / closing operation mechanism is connected to at least one appropriate position among each opening / closing lid, each rod, and the stirring rod. As a result, the straws and the stirring rod swing in the front-rear direction in accordance with the opening / closing operation of each opening / closing lid, the rice husks stored in the container portion in a piled-up state are stirred, and the rice husks are meshed with each other. There is an advantage that troubles such as becoming a discharge stop state can be solved more reliably.

    Furthermore, in the range over the left and right width of the skeleton body just above the horizontal shaft support mechanism, it had a downward slope continuous to either the lower peripheral wall of the container part on which the upper side is arranged or the hopper part delivery wall. The one having a bowl-shaped concealed jar reliably prevents the phenomenon that the rice husk accommodated immediately above the horizontal shaft support mechanism stagnates on the horizontal shaft support mechanism and remains after the entire amount is released. On top, the outflow of the rice husk flowing down along either the peripheral wall of the container part or along the hopper part sending wall will continue without stagnation, and a smoother and more reliable whole-quantity application can be realized. Become.

    If the top / bottom position of the open / closed lid in the closed state of the open / closed lid is set to a downward slope of 15 to 25 degrees, preferably 18 degrees from the base end to the rotating end, The urging force in the flow direction applied to the chaff on the top of the opening / closing lid can be increased in each step than that set at less than 15 degrees, and the opening / closing lid in the closed state than that set at an angle exceeding 25 degrees. It reduces the concentrated load of the rice husk that is stored directly above the rotating end, and can reliably prevent inadvertent leakage of the rice husk while the lid is closed. It is possible to quickly and efficiently release and spread rice husks without any itchiness immediately after opening the opening / closing lid, and even with a slight opening, it can be smoothly spread, which is almost impossible with the conventional structure. It was possible to realize the ultrathinning that was According to various conditions such as the amount of rice husk and the size of the field, it will be possible to spray evenly from thin to thick without any unevenness. Become.

    Then, the opening / closing operation mechanism has an opening / closing lid that can be temporarily fixed in either a stepwise or non-stepwise manner in a fully closed, fully open, and other appropriate multiple opening postures. In combination with the opening / closing lid with the closing posture set to a downward slope, the one with the degree adjustment unit is thinly opened immediately after opening / closing of the opening / closing lid, when fully opened, or in the middle In any case, such as when opening to an arbitrary opening, smooth and homogeneous rice husk spraying can be realized without stagnation, and the amount of sprayed discharge can be easily adjusted even during spraying As a result, the rice husk can be dispersed more efficiently and homogeneously compared to the conventional type.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
