Description

    The present invention relates to all fields related to spraying technology for transporting and spraying granular materials, powdered materials, etc. to a necessary range, and traveling vehicles such as tractors and other agricultural machines. From the field of manufacturing the spraying device that can be connected to or mounted on, as well as providing and selling the equipment and equipment necessary for its production, materials necessary for these materials, machinery and parts, for example, , Wood, stone, various fibers, plastics, various metal materials, etc., electronic components incorporated in them, control-related equipment that integrates them, fields of various measuring instruments, power to move the equipment and instruments The field of machinery, the electric power that is energy, the field of electricity that is the energy source, and the field of oil, and the fields that are generally called industrial machines, as well as the equipment and instruments are tested. , Research, field related to display, sales, import and export, general, as well as the results of their use, the equipment to build it, and the collection and transportation of garbage debris generated by the operation of equipment There are few technical fields that are almost unrelated to the related fields, the recycling field that efficiently recycles garbage waste, and other new fields that cannot be envisaged at this time.

(Points of interest)
A large amount of rice husk generated after harvesting rice is blown away by the wind if left untreated properly, and may be crushed or crushed because it will adversely affect the surrounding environment, such as being washed away by rainwater. However, after pre-treatment such as incineration or steaming to make charcoal, it has become a common practice so far to inject into the field and use as compost, The work of crushing and crushing has the problem of increasing the labor and cost of introducing machines and assigning workers, and smoke and dust generated during incineration and steaming are located near the countryside. There is a problem that it causes a great deal of trouble to pedestrians, vehicles, etc. that use cars, factories, and roads. 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 is that “the rice husk spraying system and its rice husk container are composed of technical ideas as already disclosed in Japanese Patent Laid-Open No. 11-243719”. The invention has been successfully developed and put into practical use.

    This already developed “rice husk spraying system and its rice husk container” is not shown provided on the bottom 21 of the skeleton 2 shown in the cross-sectional view of the rice husk container of FIG. The open / close shutter is opened by an external operation so that the rice husk C can be sprayed while traveling. The rice husk C discharged from the rice huller can be directly accommodated in the rice husk container 2. In this way, it can be transported to the field as it is and sprayed efficiently.

    However, when this rice husk spraying system is actually put into practical use, especially when a large amount of rice husk C is accommodated, a hollow portion is formed above the spraying port 4 as in the container shown in FIG. S occurs, gradually grows to reduce the amount of rice husk C released, and eventually stops spraying completely. It has been found that there are cases where it is impossible to do so, and that there is always a problem in ensuring continuity of work.

    Accordingly, when pursuing the cause of such release stop, the shell shape and straw of the rice husks C accommodated in a piled state, or the twigs of mixed rice straw become meshed and the opening of the spraying port 4 is opened. The fact that a bridge-shaped discharge cavity S that supports the edge portion is formed to cause the discharge to become impossible is revealed, and the existing container 2 has a means to prevent such a phenomenon. Since this was not taken into consideration, the tractor must be temporarily stopped, and the discharge cavity S must be destroyed by inserting a rod, a scoop, or the like into the inside from a supply port or spray port 4 (not shown) above the rice husk container 2. Not only is the work required, but when the tractor is stopped, if the discharge cavity S is carelessly broken without closing the spraying port 4, a large amount of rice husk C is dropped at the stop position. Tesama Even if it has to be processed after that, or even if the spraying is resumed without such a situation, the exhaust cavity S can be generated and grown again in the same way while running for a while, and it is efficient. There was a risk of disturbing proper spraying work.

    In order to eliminate such deterioration in workability of rice husk C spraying, the applicant of the present application is further provided with a skeleton body that can be connected to or mounted on a traveling vehicle, as disclosed in Japanese Patent Application Laid-Open No. 2004-121219, A container portion capable of accommodating a predetermined amount of rice husk supported by the skeleton body, and a spray port provided with an open / close shutter at an appropriate position of the bottom frame incorporated in the bottom portion thereof. In addition, an obstructing member arranged horizontally is arranged above the lower end opening of the spraying port and in the vicinity of the center of the flat cross section. The obstructing member releases the spraying port. From the point just before the vessel shell itself, straw or mixed rice straw twigs etc. meshed with each other to form a connected sedimentary structure, partly isolated, fragmented, Rice husks like traditional ones It does not become a lump, it continuously collapses and can be discharged smoothly and without delay, and it can eliminate problems such as interruption of spraying work due to the stoppage of release so far, to an efficient and homogeneous field We have also succeeded in developing a rice husk spraying device that can spray rice husks.

    Moreover, it has the container part supported by the frame | skeleton body which can be connected with a vehicle like what was disclosed by "the rice husk spraying apparatus" invention of Unexamined-Japanese-Patent No. 2005-312408, and forms the front-and-rear sending surface in the lower part. In addition to forming a hopper with an opening at the bottom of one delivery surface, the obstructing member is installed on the upper part parallel to the spraying port, and an open / close shutter is incorporated in the spraying port. The falling direction and speed of rice husks are different on each edge side, and the front and rear shapes of the cavity formed by meshing of the rice husks are positively unbalanced to promote natural collapse, so that the rice husks do not become clumpy There is also a rice husk spraying device that can discharge smoothly and smoothly without disintegrating continuously, and can achieve and enable efficient and homogeneous rice husk spraying to the field by eliminating the interruption of the spraying work due to the release stop It is already developed.

    However, the rice husk spraying device equipped with such a hopper, opening / closing shutter, and obstructing member inevitably has a drawback in that the complexity of the structure cannot be avoided and the number of parts increases. Recently, as shown in the side view of FIG. 8 of the rice husk spraying device mounted on the tractor and in use, and the side view of FIG. Is opened as one or two front and rear (or three, not shown) spraying ports 4, 4 with each spraying port 4, 4 facing backwards Opening / closing shutters 5 and 5 that can be opened are provided, and as shown in FIG. 7, a rice husk spraying apparatus 1 that can prevent the formation of the cavity S and that has a simple structure and is inexpensive is supplied. Has become like

However, the rice husk spraying apparatus 1 that opens the substantially entire surface of the bottom surface 21 of the container 2 in this way, in order to continuously discharge a sufficient amount of rice husk C, shows an open vertical dimension M or 9 shown in FIG. m must be secured sufficiently large. As a result, as shown in FIG. 8, the vertical dimension h of the container 2 is higher than the ground height H up to the top surface of the container 2 that can be safely mounted on the tractor T. The ratio must be set small, not only greatly reducing the capacity of the container 2, but also in a soft field where the tires are buried deeply, the high center of gravity forces them to run unstablely. As a result, there is a great concern about the safety, and the tendency is extreme to the type having a large opening / closing shutter 5 that opens the substantially entire bottom surface 21 as shown by a one-dot chain line in FIG. Appear in At the same time, this is a phenomenon that is most noticeable for this large open / close shutter 5. In the case of these large shutters 5, the rice straw scattered in the field by these shutters 5 during the operation of spraying rice husk C while operating the tractor. Including the waste, the operation will be hindered, and above all, with this conventional type with two or more shutters 5, thin seeding-like spraying is impossible or almost impossible. That left the problem.

(Awareness of problems)
As described above, the various rice husk spraying devices previously developed by the applicant of the present application prevent the formation of cavities in the rice husk in the container during the spraying operation, thereby preventing unexpected spray stoppage. Although it was successful in realizing efficient rice husk spraying, an increase in the number of parts and manufacturing manufac- Speaking of rice husk sprayers that have a structure that inevitably closes in terms of the price range, the rice husk sprayers that open up almost the entire bottom surface of the container that is dominant in these respects. In addition, there is a disadvantage that can be said to be a fatal point in practical use that an appropriate opening degree of the opening / closing shutter cannot be secured unless the ground clearance at the bottom of the container is sufficiently secured, and further, the container capacity is reduced and the center of gravity is increased. In addition to this new problem, in order to open and close an open / close shutter with a large closed area, there is also a problem that a complicated open / close operation mechanism using the engine output of a dedicated motor or tractor is indispensable. It was.

(Object of invention)
Therefore, the present invention can ensure a large container capacity, can ensure sufficient running stability of the mounted vehicle by lowering the center of gravity of the container, and does not require a drive source, and can open and close the spraying port. Judging from whether it is possible to develop a new rice husk spraying technology that makes it possible to open and operate the shutter easily and reliably only by manual operation, we started its development and research quickly, trial and error over many years and many prototypes As a result of repeating the experiment, this time, the presently succeeded in realizing a rice husk spraying device having a novel structure, and in the following, the configuration thereof will be described in detail together with an embodiment representative of the present invention shown in the drawings. I will state.

(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.
In other words, it has a container part in the form of a roughly casing that can be connected to or mounted on a tractor or other traveling vehicle via an attachment / detachment mechanism, and is in a single letter shape on the left and right sides of each of the two locations on the bottom of the container part. A hopper slope with a predetermined angle is formed at the important point on the bottom of the container part in the immediate vicinity of the spraying port so as to form a spraying port having a predetermined length in the front and rear direction and a funnel-shaped hopper that faces each of the spraying ports. Each of the spouts is formed with a bulge on the bottom of the triangular shape in the left and right vertical section with the top edge of the slope for each hopper as the top. This is a rice husk spraying device having a configuration in which an end is formed as an open / close end that can be opened downward, and an open / close shutter having an open / close operation mechanism that can be remotely or directly operated is incorporated.

    In other words, the container portion has a substantially casing-like shape that can be connected to or mounted on a tractor or other traveling vehicle via an attaching / detaching mechanism, and the left and right sides of the bottom portion of the container portion are arranged in the left and right directions. Forming a spray port of a predetermined length in the front and rear length that opens in a single character, and having a predetermined downward slope on both the front and rear facing walls facing each of the spray ports, or a predetermined downward slope on either one of the front and rear facing walls A hopper with a predetermined angle on the bottom surface of the container portion in the immediate vicinity of the spraying port so as to form a funnel-shaped hopper portion in which either one of the front and rear wall surfaces is arranged vertically. Each slope is formed with a bulge on the bottom of the bottom of the triangular shape in the left and right vertical section with the top edge of the slope for each hopper as the top. And the rear edge goes down It can openable closing end and without a remote or direct operable opening and closing mechanism or opening operation mechanism can be said that the chaff spraying device was made incorporating an opening and closing shutter having.

    If the configuration of the rice husk spraying device consisting of these basic configurations is shown as a more specific one, it has a generally casing-like container portion that can be connected to or mounted on a tractor or other traveling vehicle via an attachment / detachment mechanism, In each of two locations that are evenly arranged on the bottom of the container portion, a spout is formed with a single letter opening across the left and right, with the front-rear dimension of each opening set to less than 1/3 of the front-rear longitudinal dimension of the container portion. In addition, in order to form a funnel-shaped hopper portion that faces each of the spraying ports, a hopper slope at a predetermined angle is formed on each of the important points on the bottom surface of the container portion adjacent to the spraying port, and the upper edge of each hopper slope is the top. The left and right vertical cross section of the bottom of the triangle is formed on the bottom, and each spout has an opening and closing end with a front end that is wrinkled and a rear end that can be opened downward. Remotely or directly operable Closing the chaff spraying device comprising a structure in which shall become incorporate closing shutters having a work mechanism or opening operation mechanism.

    More specifically, the container portion has a generally casing shape that can be connected to or mounted on a tractor or other traveling vehicle via an attaching / detaching mechanism, and the left and right sides of the bottom portion of the container portion are arranged evenly. A spout opening is formed in which the front-rear dimension of each opening is set to be less than 1/3 of the front-rear longitudinal length of the container part, and a funnel-shaped hopper part toward each spout opening is formed. As shown in the figure, a hopper slope with a downward slope of 45 ° or more is formed at a key point on the bottom of the container part immediately adjacent to the spraying port, and a swell on the bottom of the triangular shape in the horizontal direction with the top edge of each hopper slope as the top. In addition to forming a protruding part, each spout has an opening / closing end with a front end that is a shaft-mounted end and a rear end that is capable of opening the end downward. Open / close switch with operating mechanism Potter it can be said that the chaff spraying device was incorporated in made up the.

    As described above, according to the rice husk spraying apparatus of the present invention, the spray port having a predetermined length in the front and rear length that opens in a single character form on the left and right is formed in each of the two locations that are arranged in the front and rear of the bottom surface of the container part, and these Left and right direction with each hopper slope at the top of each container hopper slope at the top of the container bottom near the spray mouth and the top edge of each hopper slope as the top so as to form a funnel-shaped hopper that faces each spray mouth In addition to forming a triangle-shaped bulge on the bottom of the vertical cross section, each spout has a front end with a wrinkle and a rear end with an open / close end that can be opened downward, remotely or directly It is designed to incorporate an open / close shutter with an open / close operation mechanism that can be operated, and the front / rear length dimension of each spray port arranged at the front / rear is a conventional one that opens almost the entire bottom surface of the conventional container section. Compared to case It is possible to reduce the downward opening size of each opening and closing shutter opening and closing end, thereby making it possible to set the bottom of the container part lower, and to ensure a large container capacity accordingly, In addition, the low center of gravity of the container can be realized to ensure the running stability of the mounted vehicle in a soft field, and the rice husks and other granular materials and powders that are applied to each open / close shutter when closed The load of the container is greatly reduced by reducing the area of each spraying port, and it has excellent characteristics that it can be opened easily and reliably by manual operation without the need for a drive source. It becomes.

    In addition, a slope for hoppers of a predetermined angle is formed at a key point on the bottom surface of the container part immediately adjacent to the spraying port, and a bulging part on the bottom surface of a triangular shape in the horizontal direction is formed with the top edge of the slope for each hopper as the top. This eliminates any flat or trapezoidal parts where particulates or powders stay in the container part, and during the spraying operation, each spraying port for contained items such as rice husks and other particulates and powdery substances in the container part It is possible to reliably prevent a hollow portion from being formed like a bridge at a location facing the surface, and to achieve an effective effect of always realizing an efficient spraying operation without an unexpected spray stop phenomenon.

    In addition, the front end of the open / close shutter is a hooked end, and the rear end is an open / close end that can be opened downward. In addition, it is possible to reliably prevent the opening and closing operation from occurring due to clogging, and even if the opening and closing end contacts the ground during spraying, the opening and closing end is temporarily lifted up. Since it will operate automatically and promptly to restore the open state again and maintain uniform spraying as it is, it will impede stable travel of tractors and other traveling vehicles that travel with the container part connected or mounted. There is also an advantage that inadvertent breakage of the open / close shutter can be prevented in advance.

    Furthermore, both the front and rear opposing wall surfaces facing each spraying port have a predetermined downward slope, or either one of the front and rear opposing wall surfaces has a predetermined downward slope, and either one of the front and rear opposing wall surfaces is arranged vertically. In order to form either one of the funnel-shaped hopper part, even if the slopes for hoppers of a predetermined angle are respectively formed on the bottom surface of the container part in the immediate vicinity of the spraying port, the particulate matter in the container part. And flat parts and bowl-shaped parts where powdery substances stay, etc. can be eliminated at all, and it can be surely prevented that a hollow part facing the hopper part is formed during the spraying operation. Become.

    And in the case where the front and rear dimensions of the spraying ports formed at two locations in the front and rear uniform arrangement on the bottom surface of the container part are set to less than 1/3 of the front and rear dimension of the container part bottom surface, the front and rear dimensions are set to 1/2 or more. Compared to the conventional product, the load due to the granular material and powder contained in the container part applied when each open / close shutter is closed is greatly reduced, enabling manual opening operation that does not require a drive source, and manually It is also possible to perform more lightly and smoothly even by, and also has the effect of reducing the downward opening size of each opening and closing shutter, and more reliably achieving the expansion of the capacity of the container part and the lowering of the center of gravity. I can expect.

    In addition, when the slopes for hoppers with a downward slope of 45 ° or more are formed at the important points on the bottom of the container part immediately adjacent to the spout, the distance between the slopes for hoppers is lower than that with a downward slope of less than 45 °. As a result, it is possible to more reliably prevent the phenomenon that bridge-shaped cavities are formed by rice husks and other particulates and powders that face the surface, and to smoothly collapse the cavities that are often formed during spraying. Compared to the previous ones, a practical effect is achieved that it is possible to realize a much more stable spraying operation.

In implementing the present invention having the configuration as described above, the best or desirable mode will be described.
The container part can store rice husk in an amount that can be efficiently sprayed on the field, and can function to distribute the rice husk homogeneously through the spout at the bottom of the rice husk. It should be made of a material that is as light as possible so that it can be connected to or loaded onto a tractor, trailer, or truck that travels on relatively soft land such as rice fields or fields, and it is compact for storage and transportation. It is desirable to adopt something that can be converted into a skeleton body such as a metal frame made of a cylindrical or bag-shaped net or sheet material that has sufficient strength to withstand the loading of rice husks, Or it becomes very convenient when it is a box-shaped container or a generally case-like one in which thin plate materials are combined in a foldable manner.

    The attachment / detachment mechanism allows the appropriate location of the container portion to be detachably connected or mounted to the appropriate location such as a tractor, trailer, or truck, and allows the connected or mounted container portion to be grounded as necessary. It is possible to exert a lift-up function that can be lowered and raised to a predetermined height, and a container part full of rice husks must be capable of being connected or mounted with sufficient strength. It should be compatible and usable with the connecting part of the vehicle, and it is desirable that the connection or mounting operation to the vehicle can be performed easily and quickly, whether it is provided in a tractor or other traveling vehicle, Or outside the tractor or other traveling vehicle and the container that can be either one provided at the appropriate place in the container section And conveniently removed from both the can be made available, such as other vehicles or containers.

    The bottom of the container part can form or attach each spraying port and their opening / closing shutters, hoppers, etc., and can protect them from being lost due to breakage or deformation when grounding, and the container part itself It is not necessary to form the entire bottom part in a flat plate shape, and it is sufficient if it is formed by a frame material part that can stand on its own, rice husks, etc. It is desirable to further reduce the weight by forming a substantial bottom portion for accommodating the granular material and powdery material by each hopper.

    The hopper part can drop dust and powdery substances such as rice husks contained in the container part naturally onto the ground through a sprinkling opening that opens in a single letter shape across the left and right widths around the bottom of the container part. It is formed in two funnels facing each spraying opening that is opened at two places on the bottom of the container part and arranged at a predetermined angle on the bottom of the container part in the immediate vicinity of each spraying mouth. Each of the slopes for the hopper is formed, and a bulging portion on the bottom surface of a triangular shape in the left and right direction vertical section with the top edge of each hopper slope arranged between the front and rear spray ports as a top part must be formed, Whether at least both of the front and rear facing walls facing each of the spray ports have a predetermined downward slope, or either one of the front and rear facing walls has a predetermined downward slope, and either one of the front and rear facing walls is arranged vertically of It should be funnel-shaped on the other hand, and the slope for the hopper should be designed to prevent the phenomenon that the spraying stops due to the formation of a cavity at the top of the spraying port, and to enable a smooth fall. Each of them may be set to an inclination angle of 45 ° or more, and either one of the front and rear hopper slopes may be formed in a substantially vertical wall shape continuous to the corresponding front and rear inner wall surfaces of the container portion.

    In other words, the hopper part is continuous below the front wall and the rear wall of the container part, respectively, and before and after gradually reducing the opening area toward the two spraying ports arranged at the front and back. It is formed from a slope for hoppers and a vertical surface consisting of left and right side walls of the container part that concealably close the left and right side ends of the front and rear hopper slopes, and the rear upper end edge of the front side hopper part and the rear side hopper part It can also be said that the front upper edge is continuous so as to form the top of a triangular shape in the left-right direction vertical cross section, and the flat portion or the hook-like portion where the rice husk stays is excluded.

    The spout opening forms a lower opening part of each hopper part, and can be opened and closed by an opening / closing shutter so that the container part can be filled with a predetermined amount of particulate matter such as rice husk and powdery matter, By setting the front and rear length as small as possible, it is easy to open and close or open the shutter by manual operation.In addition, by opening it, granular materials such as rice husks and powdered materials contained in the container part can be removed. It must function to enable uniform and continuous stable spraying, open in a single letter shape across the left and right of each of the two locations at the front and rear of the bottom of the container part, and have a predetermined length in the front and rear. More specifically, it opens in a single character shape across the left and right at each of two locations that are evenly arranged on the bottom of the container portion, and the front and rear dimensions of each opening It is desirable to set it to less than 1/3 of the longitudinal dimension of the surface, and by arranging the front and back evenly on the bottom of the container part, the amount of spraying of granular materials and powdery materials can be reduced for each front and rear spraying port. It becomes possible to divide and discharge evenly, and by setting the front and rear dimensions of each spray port to less than 1/3 of the front and rear length of the container bottom, the pressure on the open / close shutter due to the weight of the container is greatly reduced. For example, an open / close shutter with a structure in which a chain is hung on and interlocked with a gear incorporated in each shutter shaft, and it does not have to be dared to operate it. If it exceeds 1/3 of the length at the bottom of the container, the opening operation can be performed without the help of a motor or engine. But so that the results in the disadvantage of too excessive operating burden on the worker to the extent hardly difficult.

    The open / close shutter is opened in a single letter shape in the left and right positions at the two front and rear positions on the bottom of the container part, and each spray port formed in a predetermined dimension in the front and rear length is individually and / or simultaneously operated manually. Even if it is a thing, it fulfills the function of enabling the opening operation, and it is incorporated in each spraying port on the bottom of the container part, the front end is a hooked end, the rear end can be opened downward None, it must have an open / close operation mechanism that can be operated remotely or directly, or an open operation mechanism, and the open state of the spraying port can be adjusted steplessly or stepwise, so that it can The amount of discharge can be adjusted freely, so that a person operating a tractor, trailer, truck, or other traveling vehicle can remotely control from the driver's seat outside the container section. It is desirable to be able to perform a closing operation or an opening operation, and to include various auxiliary mechanisms that are incidentally necessary, such as providing a safety device that can temporarily fix the closed state as necessary. Of course it is also possible to do.

As mentioned above, the open / close shutter open / close operation mechanism does not depend on the motor, hydraulic circuit, or other special drive source for each open / close shutter. Regardless of the function, it is desirable that it can be operated both manually and closed, and can be operated remotely from the driver's seat of a tractor or other traveling vehicle using wires or control rods. Only the shutter opening mechanism does not require a motor, hydraulic circuit, or other drive source for each open / close shutter, and allows all open / close shutters linked by chains to be opened manually. Even if the advantage of being able to simplify and simplify the structure is obtained, To all the opening and closing shutter closure (closure as in conjunction with all or separately closed) it takes work to.
In the following, the structure of the present invention will be described in detail together with an embodiment representative of the present invention shown in the drawings.

(Example operation)
As shown in FIG. 2, the rice husk spraying apparatus 1 of the present invention having the above-described configuration simply connects the attachment / detachment mechanism 22 provided at an appropriate front position of the container portion 2 to the connection location a at the rear portion of the tractor T. 1 to 3, the open / close shutters 5 and 5 shown in FIGS. 1 to 3 are closed and temporarily fixed to the opening operation mechanisms 53 and 53 in FIG. After closing, the rice husk C is filled through the top opening of the container part 2 and then moved to the target farm field to start spreading the rice husk C.

    As indicated by a two-dot chain line in FIG. 1, the open / close shutters 5 and 5 in the closed state have hoppers of the front and rear hoppers 3 and 3 in the downward pressure P generated by the total amount of the rice husk C accommodated. Only the load pressures PB and PB indicated by the wavy arrows in FIG. 1 are applied except for the reduced pressures p, p,...

    As shown in FIG. 2, after moving the tractor T that has entered the field to the spray start position, the remote control lever (not shown) provided in the driver's seat is operated, For example, the unlocking operation mechanism 53 disposed rearward is unlocked, and only the rear opening / closing shutter 5 is opened as shown by the solid line in FIG. The husks C such as a flat surface and a bowl-shaped portion are dropped on the upper portions of the slopes 31 and 31 (including the bulge portion 32 on the bottom surface). There is no obstructing shape part, and the inside of the container part 2 is formed only from a vertical wall surface and a slope with a downward slope. The occurrence of this is surely prevented.

    In addition, the longitudinal length of each of the front and rear spray ports 4 and 4 shown in FIG. 1 is set to a dimension that is 1/3 to 1/5 of the longitudinal length of the bottom surface 21 of the container part 2 and is opened and closed. The longitudinal length of the front / rear opening / closing shutters 5 and 5 is either the same as the longitudinal length of the bottom surface 21 of the container 2 shown in FIG. Compared with the conventional open / close shutters 5 and 5 that have been set, the load pressure PB due to the load of the chaff C applied to the single open / close shutter 5 shown in FIG. 1 can be greatly reduced. The opening operation force required for each opening operation mechanism 53, 53 can be reduced, and the opening operation can be performed only manually without the need for a motor or other drive source.

    Further, the longitudinal lengths of the front and rear opening / closing shutters 5 and 5 are reduced, and compared to the open vertical dimension M (m) of the conventional opening / closing shutters 5 and 5 shown in FIG. The opening / closing dimension m of the open / close shutters 5 and 5 shown in FIG. 5 can be remarkably reduced, and even if the distance between the bottom surface 21 of the container part 2 and the ground surface is shortened accordingly, more stable vehicle traveling and spraying are possible. The total height h of the container part 2 that is restricted by the ground height H up to the top surface of the container part 2 shown in 2 is limited to the ground height H up to the top face of the conventional container part 2 shown in FIG. It is possible to set larger than the overall height h to be received, and it is possible to increase the capacity of the rice husk C in the container part 2 and to lower the center of gravity.

    After discharging all the rice husk C accommodated above the hopper 3 of the spray port 4 arranged at the rear and confirming that the rice husk C spraying from the rear spray port 4 has stopped, the remote control lever (not shown) is operated. The front opening operation mechanism 53 in FIG. 1 is released, the front opening / closing shutter 5 is opened, and the rice husk C left on the front hopper 3 in the container 2 through the spray port 4 arranged in the front is removed. Disperse evenly and complete the distribution of all the rice husks C contained.

    After all the rice husks C have been sprayed, the tractor T is stopped, and the front / rear opening / closing shutters 5 and 5 are closed either manually or by appropriately operating a remote-controlled closing mechanism. Then, after engaging with the opening operation mechanism 53, 53 and temporarily fixing, a new rice husk C is filled again from the opening of the top surface of the container part 2, and the same spraying operation can be continued. After moving to the storage place, the container part 2 is slowly lowered by a dump mechanism (not shown) provided at the connection point a of the tractor T, and is stably grounded on the ground, and then separated from the connection point a and spraying work. Exit.

    The rice husk spraying apparatus 1 taken up in FIG. 4 has hopper slopes 31, 31 that form a bottom upper bulging portion 32 between the spraying ports 4, 4 of the hopper portions 3, 3 disposed before and after the bottom surface 21 of the container portion 2. In addition, the bottom wall portion 23 of the container 2 facing the hopper slopes 31 and 31 of the upper bulge portion 32 on the bottom surface, and the rear wall wall are gently inclined in the front-rear direction with the central top portion as a boundary. 24. Each of the hopper slopes 31 and 31 comprising the lower part of the lower part is formed in a vertical plane, and each of the hopper parts 3 and 3 has an asymmetrical shape in front and back, which promotes the collapse and fall of the contained rice husk. No part is formed.

    Similarly, each of the rice husk spraying devices 1 and 1 shown in FIGS. 5 and 6 also does not have a cavity part of the front and rear object shape formed on the front and rear hopper parts 3 and 3, and therefore is not expected. Stable rice husk spraying will be done without losing spraying due to unforeseen circumstances.

(Effect of Example)
The rice husk spraying apparatus 1 according to the first embodiment having the above-described configuration is not limited to the characteristics described in the section of the effect of the present invention. The front and rear long dimension is set to be 1/3 to 1/5 of the front and rear long dimension of the container part 2 bottom surface 21, and as shown by a two-dot chain line in FIG. Only the load pressures PB and PB reduced to 1/3 to 1/5 of the load pressure P by the rice husk C are applied, and the operating force required to open each of the open / close shutters 5 and 5 is greater than the previous one. Therefore, there is an advantage that even a manual operation by a weak elderly person or a woman can be easily released.

    In addition, in the container part 2 above each spraying port 4, 4, including the hopper parts 3, 3, the shape that holds the rice husk C, such as a flat surface or a bowl-like surface, is completely eliminated, Each hopper slope 31 has a downward slope of 45 °, and a bottom surface of a triangular shape in the left-right vertical section with the junction between the upper edges of the hopper slopes 31, 31 arranged between the front and rear spray ports 4, 4 as the top. The upper bulging portion 32 is formed, and it is possible to reliably prevent a situation in which a hollow portion is formed during the discharge of the rice husk C to exhibit a bridge state, and a smooth and stable spraying is always realized. .

    Further, as described above, the front and rear opening / closing shutters 5 and 5 having a reduced longitudinal length can be clearly understood by comparing the downward opening size m (M) of the conventional opening and closing shutters 5 and 5 of FIG. Thus, when connected to the tractor T, the required vertical dimension from the ground surface to the bottom surface of the bottom surface 21 of the container part 2 can be reduced, the container part 2 can be lowered in the center of gravity, and the conventional type shown in FIGS. As shown in the container section, the overall height h of the container section 2 with a limit on the height upper limit H of the container section 2 that can ensure the traveling safety of the tractor T is compared with the conventional type in FIG. Therefore, the capacity of the container part 2 can be increased, and the more efficient operation of spreading the rice husk C can be realized.

    Furthermore, the opening operation mechanisms 53 and 53 have only a function of enabling the front and rear opening / closing shutters 5 and 5 to be opened individually, realizing a light opening operation while the tractor T is running, If it is stopped, it can be directly closed by a simple operation, and it does not employ a complicated remote closing mechanism, and a remote control lever, a pulling wire and a locking claw (not shown) (Not shown in the drawings), etc., so as to be formed by combining as simple a part as possible, so as to realize a further simplification, weight reduction, and price reduction of the rice husk spraying device 1, and can be widely adopted and spread. The effect of becoming a thing can be expected.

    In the case of the rice husk spraying device 1 shown in FIG. 4, a bulge on the bottom surface comprising hopper slopes 31, 31 having a gentle downward slope on the bottom surface 21 between the front and rear spray ports 4, 4 of the container unit 2. 32, but the lower ends of the front and rear wall surfaces 23, 24 of the container part 2 are opposed to the vertical surface-shaped slopes 31, 31 for hoppers, respectively, and the longitudinal cross-sectional shape is unbalanced in the front-rear direction. The vertical hopper slopes 31, 31 smoothly flow and descend the rice husk C being sprayed to reliably prevent the formation of the cavity, and Similar to the rice husk spraying device 1 shown in FIGS. 1 to 3, the effect of lowering the center of gravity and increasing the capacity can be achieved.

    The rice husk spraying devices 1 and 1 shown in FIGS. 5 and 6 also have the arrangement relationship of the front and rear spraying ports 4, 4, the inclination angles of the hopper slopes 31, 31,. Although there is a slight difference in the vertical cross-sectional shape of the left and right direction, the smooth flow and dispersion of the rice husk C can be promoted to prevent the formation of the cavity, and the low center of gravity and capacity of the container part 2 can be prevented. As a result, it is possible to realize the distribution of rice husk C, which is excellent in safety and work efficiency.

(Conclusion)
As described above, the rice husk spraying device according to the present invention can achieve the intended purpose evenly by its novel configuration, and the number of parts is not greatly changed compared to the conventional rice husk spraying device. Since it can be realized by a simple structure, it is easy to manufacture, can be provided at a relatively low price, and can further improve the efficiency of the series of operations from hulling work to transportation to the field, spraying, Farmers with problems such as labor shortages and aging are very effective in improving work efficiency, and rice husks that are generated in large quantities every year and are difficult to process are used as an effective organic material.
