(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 of causing a great deal of trouble to pedestrians and vehicles, and recently, there is a tendency to avoid such processing.

(Conventional technology)
However, in recent years, the rice husks after threshing are sprayed on the field as they are, and they are sown into the soil and reduced to the ground, leading to improvement of the soil due to the properties of the rice husk and its unique shell structure, and composting. As the fact that the fertilization effect of other organic fertilizers can be enhanced has become increasingly clear, there is an interest in the technology of how to efficiently spread rice husks discharged from rice hullers on the field. The applicant of the present application paying attention to such circumstances has already succeeded in developing and putting to practical use the rice husk spraying system and its rice husk container disclosed in JP-A-11-243719.

    The rice husk spraying system 1 and its rice husk container 5 that have already been developed have a lift mechanism L that can be held in the form of a forklift at the rear of the tractor T, as shown in the perspective view of the spraying operation in FIG. The open / close shutter C5 at the bottom of the container body C that is placed thereon is opened by an external operation, so that the rice husk C can be sprayed while traveling, and is discharged from the huller. The rice husk thus made can be directly stored in the rice husk container 5 and can be transported to the field as it is and efficiently dispersed.

    However, when the rice husk spraying system 1 is actually put into practical use, particularly when a large amount of rice husk is accommodated, it is shown in the longitudinal sectional view of the container at the stage where the rice husk discharge is stopped in FIG. As shown in the figure, cavities S and S are generated in the upper parts of the spraying ports 4 and 4, respectively, and gradually grow to reduce the amount of rice husks released, and eventually the spraying is completely stopped. Occasionally, it can lead to a situation where it becomes impossible to uniformly spray the field scene while leaving rice husks, and it turns out that it always leaves a problem in ensuring continuity of work did.

    Therefore, when pursuing the cause of such release stop, the vessel shape and straw between the rice husks accommodated in the piled state, or the twigs of mixed rice straw become meshed and become the opening of the spraying port 4 The fact that a bridge-shaped discharge cavity S that supports the edge portion is formed and the discharge becomes impossible is revealed, and the existing container 5 has a means to prevent such a phenomenon. Because it was not taken into account, the tractor must be stopped once, and the discharge cavity S must be destroyed by inserting a rod, a scoop or the like into the inside from the supply port or spray port 4, 4 (not shown) above the rice husk container 5. Not only does extra work be required, but when the tractor is stopped, if the discharge cavity S is inadvertently broken without closing the spraying ports 4 and 4, a large amount of rice husks are brought to the stop position. Let fall Even if it is necessary to process after that, or even if spraying is resumed without such a situation, the discharge cavities S and S may be generated and grown again in the same way while running for a while. Therefore, there was a risk of hindering efficient spraying work.

In addition, including the case where the entire amount of rice husks can flow smoothly to the funnel-shaped spout 4 without forming the bridge-shaped discharge cavity S, for example, Japanese Patent Application Laid-Open No. 2001-63445, “Trailer”. The invention and the apparatus described in Japanese Patent Laid-Open No. 2001-120023 “trailer” invention, Japanese Patent Laid-Open No. 2001-95338 “trailer” invention, Japanese Patent Laid-Open No. 11-63445 “rice husk spraying system and its rice husk container” invention, etc. In order to spread rice husks, while operating in the lift mechanism L of the forklift at the rear of the tractor T, while trying to spread the appropriate amount of rice husks uniformly on the field scene, visually check that the appropriate amount of rice husks is spread. When the operator operating the tractor T adjusts and opens the opening / closing degree of the opening / closing shutter C5 at the bottom of the container 5 by an external operation. During the repeated opening / closing adjustment of the opening / closing shutter C5, there may be a case where the rice husk is clogged between the lower edge of the lower end opening and the upper surface of the opening / closing shutter. In addition to the above-described measures for avoiding the bridging phenomenon in the rice husk container 5, the measures for avoiding this clogging phenomenon of the open / close shutter can be said to be a major issue.

(Awareness of problems)
This invention is a rice husk spraying device having a structure in which the spraying ports 4 and 4 having the opening and closing shutters are formed at the bottom of the rice husk container 5 as described above. In particular, a countermeasure for avoiding the clogging phenomenon of the opening and closing shutters has been proposed previously. As rice husk farming is one of the key industries in Japan, finding and providing countermeasures to avoid the clogging phenomenon of opening and closing shutters that can be applied to any rice husk spraying equipment. We thought that it was indispensable for efficient management.

(Object of invention)
The present invention relates to the handling of granular materials that enable the granular materials accommodated in containers or containers or the like to be efficiently discharged through the bottom opening, and in particular, the rice husk generated by threshing is contained in the soil of the field. To reduce the amount of rice husks, the equipment mounted and mounted on the trailer is towed by a trailer. The situation that it becomes difficult to improve the work efficiency of rice husk spraying because it is impossible to avoid the phenomenon that the spraying work cannot be continued by making it impossible, or the rice husk continues to be released as it remains open In view of the frequent occurrence of gas, it is possible to realize a technology that enables smooth and efficient spraying without delay from the start of discharge to the completion of discharge of the entire amount. As a result of long-term development and research, and repeated trial and error over many years, and many trial productions and experiments, we finally succeeded in realizing a rice husk spraying device with a new structure. In the following, the configuration will be described in detail together with an embodiment representative of 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.
It has a skeleton body in which a mechanism that can be connected to or mounted on a traveling vehicle such as a tractor or a trailer, and a container portion that is supported by the skeleton body and can accommodate a predetermined amount of rice husks, at the bottom thereof. Has a bottom frame provided in an integral structure or a detachable structure, and at a suitable position of the bottom frame is a funnel shape that reduces the opening area from the upper end opening toward the lower end opening. The part can be closed or opened by moving forward or backward in the horizontal direction by an operation from the outside, and an end part in the direction of opening movement is formed higher than the end part in the direction of closing movement. A rice husk spraying device having a configuration in which a spraying port provided with an open / close shutter regulated so as to reduce the gap with the lower end opening is provided.

    As described above, according to the rice husk spraying apparatus of the present invention, the end of the opening / closing shutter in the direction of opening movement is formed at a higher position than the end of the closing movement of direction, When closing and opening, it is possible to reliably prevent clogging of the rice husk between the lower edge of the lower end opening and the upper surface of the opening / closing shutter, and the rice husk remains in the container part during spraying. Even when closing the open / close shutter, make sure that the open / close shutter can be closed reliably, and after the work, such as intensive spraying to one place due to poor closing of the open / close shutter, or sprinkling of the rice husk with a scoop Even if you open and close the open / close shutter multiple times until you finish spraying the entire amount of rice husk in the container, And no, it is possible to expect a feature that can be homogeneously sprayed against field to the end.

    For example, like an open / close shutter represented by the embodiment, it is formed in an inclined surface shape having a predetermined gradient so as to gradually increase from the forward direction end when closing to the backward direction end when opening. In this case, when the open / close shutter is slid from the closed state to the open state, the gap between the lower end opening of the spray port and the upper surface of the open / close shutter gradually increases as the slide moves. It is possible to prevent crusts from clogging in the gap, and this time, when closing the opening / closing shutter again, the inclined upper surface of the sliding opening / closing shutter is between the lower opening of the spraying port and the upper surface of the opening / closing shutter. The effect which pushes back so that the rice husk which exists in this may be discharged to the sprinkling mouth side, and prevents the situation which becomes impossible to close will be acquired.

    In particular, in the case where the opening / closing shutter is urged upward in the retracting direction end and further provided with a roller at the end of the retracting direction, the opening / closing shutter is provided between the lower edge of the lower end opening and the opening / closing shutter. The gap is minimized, clogging of the rice husk is prevented, and the opening / closing operation of the opening / closing shutter can be made stable and reliable at all times, and the backward direction when opening from the forward direction end when closing In the case of an open / close shutter formed in an inclined surface shape having a predetermined gradient so as to gradually increase toward the end, a gap between the lower end opening of the spraying port and the upper surface of the open / close shutter is associated with the opening movement at the time of opening. When closing, the crust is prevented from being clogged by pushing the rice husk back to the spray port side, and the effect of reliably avoiding the situation of being unable to open or close can be expected.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The skeletal body supports the container portion containing the rice husk from the outside to reinforce the container portion to ensure the desired loading capacity of the rice husk and to reduce the weight of the container portion. A mechanism that can be connected to or mounted on a traveling vehicle such as a tractor or trailer must be incorporated, and by adopting a structure that can be disassembled or folded as appropriate, storage and transportation are possible. In this case, it is possible to handle it in a small size, which is advantageous for convenience and economy. Therefore, sufficient consideration should be given not only to the components but also to the combined structure of each part. Should.

    The container part can hold rice husk in an amount that can be efficiently sprayed on the field by holding the outer multiple appropriate places on the skeleton body, and the lower end opening is connected to the bottom frame and the rice husk is connected through the spraying port. It should be able to be connected to or loaded on tractors, trailers or trucks that run on relatively soft land such as fields and fields after harvesting from autumn to winter. It should be made of a material that is as light as possible, and it is desirable to use a material that can be miniaturized for storage and transportation. It is very convenient to use a bag-type sheet material or a box-type container in which thin plate materials are combined in a foldable manner.

    The bottom frame is located at the bottom of the container part, receives the total amount of rice husk accommodated in the container part, and fulfills the function as a part of a skeleton body for incorporating a spray port provided with an opening and closing shutter, It may be formed as a structure integrated with the skeleton body as a lower structure part of the skeleton body, but considering the efficiency of manufacturing, transport, storage, installation or repair of other components, inspection, etc. It should be as represented by the structure taken up in the examples described later that are detachable from the lower part of the skeleton.

    The open / close shutter can open and close the spray port that opens to the bottom frame, and it can adjust the open state of the spray port steplessly or stepwise to freely adjust the amount of rice husk released, which will be described later It is desirable to have a structure that allows a person operating a tractor, trailer, truck, or the like to open and close from the outside of the skeleton body or bottom frame, as represented by the structure taken up in the embodiment. Of course, it is possible to incorporate various auxiliary mechanisms that are incidentally necessary, such as providing a safety device that can temporarily fix the closed state as necessary.

    The opening / closing shutter has a substantially flat plate shape, and is supported so that the forward direction end when closing is slidable in the horizontal direction and the backward direction end when opening is swingable upward. And a biasing means for constantly biasing the end in the backward direction toward the upper side, and the end in the backward direction is contacted and rolled along the funnel-shaped lower side wall surface continuous from the lower end opening to the upper end opening. A structure having a movable roller, or a structure having an inclined shutter surface set to a predetermined gradient so as to gradually increase from the forward direction end when closing to the backward direction end when opening. In addition, it is formed in a substantially horizontal flat plate shape, and the edge in the retracted direction at the time of opening can be in contact with the bottom edge of the bottom frame spout opening in the closed state to prevent clogging made of elastic material The piece protrudes upward It is also possible to form the structure.

    The spout serves to spread the rice husk contained in the container part in a state in which the amount of discharge can be adjusted, and to close and stop the discharge by closing the rice husk from the upper end opening to the lower end opening. It must have a funnel shape that reduces the opening area as it goes toward the bottom, and the lower end opening must be provided with an open / close shutter that can be operated to open and close the external umbrella. One or more are formed at appropriate locations on the bottom frame. The outer peripheral edge of at least the upper end opening should be smoothly continuous with the bottom frame and the inner peripheral wall of the container part above, and the upper end opening should be a plurality of adjacent shapes. In this case, the adjacent top edges of the adjacent ones are connected and connected so that the outer peripheral edge of the top opening is a ridge structure. It is desirable to those obtained by dividing.

The hindering member prevents the rice husks deposited on the spraying ports from engaging with each other, creating a connected sedimentation structure and preventing them from being discharged. In order to prevent the meshing, it is possible to have a function of making part of the connected deposition structure impossible to form, such as a rod shape, a thread shape, a plate shape, etc. In addition to being bent or shaped like a bent rod or plate, the cross-sectional shape of the rod can be round, triangular, quadrangular, or more polygonal. Thin rods (including wire rods) or straight triangular cross-section rods, with straight triangular cross-section rods in a cross-sectional arrangement with the apex of the cross section at the top, and both ends of the bottom frame at appropriate locations It shall be attached or detachably attached to In addition, it is a straight thin plate material that has a cross-sectional arrangement in which the long side direction of the cross section is up and down, and both ends thereof are attached to the bottom frame at appropriate positions or detachably attached. it can.
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.

    The example shown in the cross-sectional view of the main part of the rice husk spraying device of FIG. 1, the perspective view of the bottom frame of FIG. 2, and the cross-sectional view of the main part of the rice husk spraying device of FIG. A bottom frame with a spray port having an open / close shutter is detachably provided, and an obstructing member made of a straight thin bar is horizontally disposed at a position above the center of the flat cross section of the lower end opening of the spray port. The typical Example in the rice husk spraying apparatus of this invention which consists of the fundamental structure formed as follows is shown.

    As shown in FIG. 1 and FIG. 2, the rice husk spraying device 1 is formed in a rectangular frame shape, and a bottom frame 3 in which two spraying ports 4 and 4 that open in a substantially rectangular shape in front and rear are opened. Each of the bottom ends of the fence-type skeletons 21, 21,...

Tie the place to the appropriate position of the fence-type skeleton parts 21, 21, ..., and join the bottom opening to the top peripheral edge of the bottom frame 3 so as to be sealed, and fix it with a mounting frame (not shown) The container part 5, the fence-type skeleton parts 21, 21, ... and the bottom frame 3 are each disassembled into individual parts, Furthermore, the container part 5 and the fence-type skeleton parts 21, 21, ... should be folded and transported and stored. And it has a possible structure.

    Each of the spray ports 4, 4 of the bottom frame 3 is formed in a funnel shape that gradually reduces the cross-sectional area of the planar opening from the upper end opening 41 toward the lower end opening 42. The peripheral edge portions of 41 and 41 are formed so as to form the same funnel-shaped inclined surface until they contact the peripheral edge of the bottom frame 3 or contact the peripheral edges of the adjacent spout 4, 4 upper end openings 41 and 41. In this way, the bottom opening of the container portion 5 is connected, and the top surface of the bottom frame 3 corresponding to the lower side of the space in which the rice husk is accommodated is completely free from any planar shape portion that prevents the rice husk from flowing down without stagnation. It is said.

    The bottom frame 3 is provided with slide-type opening / closing shutters 43, 43 that can open and close each of the spray ports 4, 4 lower end openings 42, 42. The opening / closing shutters 43, 43 are mutually connected. It is coupled to an integral flat plate, and can be freely stepped by an open / close lever 44 attached to the lift mechanism L. The spray ports 4 and 4 can be opened and closed and the opening degree can be adjusted. In addition, a temporary fixing mechanism (not shown) for temporarily fixing the open / close state or the opening adjustment state is provided.

    And in the approximate center which is substantially orthogonal to the funnel-shaped cross section just below the upper end openings 41, 41 of the spouts 4, 4, the obstruction member 6 made of a square cross section and a straight steel rod or steel pipe, It is installed horizontally in a state in which the diagonal is directed in the vertical direction, and both end portions thereof are integrated with the inner peripheral wall surface of each spraying port 4, 4 by welding or bolt / nut connection, etc., as shown in FIG. When viewed from the side, each of the blocking members 6 and 6 is disposed so as to be within the range of the longitudinal sectional shape of the bottom frame 3.

    Further, as shown in the perspective view of the bottom frame of FIG. 4 and the cross-sectional view of the main part of the rice husk spraying device for spraying the rice husk of FIG. In addition, it is bent into an inverted U-shape or a roll-over U-shape toward the top, and the triangular cross-section saddle receiving plates 61, 61 are vertically arranged along the horizontal bar portion protruding in the center. It is assumed that it is joined together in a state of being directed upward, and a bolt / nut structure or an installation tool that does not require a tool to be inserted and engaged between the inner wall surfaces of the spray ports 4, 4 facing each other from above is required. As shown in FIG. 5, when viewed from the side, the hook receiving plates 61, 61 of the inhibition members 6, 6 have predetermined dimensions above the vertical cross-sectional shape of the bottom frame 3. Can be arranged to protrude

    The front and rear opening / closing shutters 43 and 43 shown in the side view of the cross-sectioned bottom frame in FIG. 6 are formed in a flat plate shape that can close the lower end openings 42 and 42 of the spray ports 4 and 4, respectively. The end in the forward direction is slidable in the horizontal direction, and is supported so that the end in the reverse direction when opening on the opposite side is swingable upward, and the end in the reverse direction is always directed upward. A biasing means such as a coil spring or a leaf spring (not shown) for biasing is provided, and at the end in the retreat direction, the bottom wall surface of the funnel is continuous from the lower end opening 42 to the upper end opening 41. A roller 43a, 43a that can roll is attached to the shaft.

    The example shown in the side view of the cross-sectioned bottom frame in FIG. 7 shows that the respective closing surface portions of the opening / closing shutters 43 and 43 are retracted from the end in the advancing direction at the time of closing when the rear opening is performed on the opposite side. A flat plate shape having an inclined surface with a predetermined gradient so as to gradually increase toward the end of the direction is formed, and the structure is slidable in the horizontal direction while maintaining the predetermined gradient.

    Further, the open / close shutters 43 and 43 shown in the side view of the bottom frame shown in FIG. 8 have a flat plate shape capable of closing the spray ports 4 and 4, respectively, and are slid in the horizontal direction to move the spray ports 4 and 4. 4 can be opened and closed, and at the end in the retracted direction at the time of opening, the gap formed between the edge portion of the lower end opening 42 of the spray port 4 can be closed and sealed The clogging prevention pieces 43b, 43b made of soft synthetic resin or soft foamed resin are fixed and integrated so as to protrude upward.

(Operation of Example Invention)
As shown in FIG. 3, the rice husk spraying apparatus 1 of the present invention having the above-described configuration is accommodated in the skeleton body 2 and connects the bottom surface openings without gaps along the peripheral surface of the top surface of the bottom frame 3. The rice husk C discharged by the threshing operation was supplied into a vinyl sheet container section 5 which was stretched by binding a plurality of locations on the outer peripheral wall to appropriate positions of the fence-type skeleton sections 21, 21,. It is mounted on a tractor (not shown) via a lift mechanism L, raised to a predetermined height above the ground suitable for spreading rice husk C, and the open / close lever 44 is rotated while traveling at a constant speed. If the opening / closing shutters 43 and 43 are adjusted to the optimum opening degree, they gradually fall from the rice husk C deposited on the lower side of the container part 5 through the spray ports 4 and 4, and the container shape is formed by discharging the rice husk C. Contaminants such as When the arcuate bridge-type discharge cavity S, which is gradually generated and developed in combination, reaches the obstruction members 6 and 6, the meshing state of contaminants such as rice husks C and twigs is fragmented. The further upward development is hindered, and the falling of the rice husk C is continuously continued by the division of the meshing state, and until almost the entire amount accommodated in the container part 5 is released. It becomes possible to spray evenly without delay.

    Since the obstructing members 6 and 6 are attached with the diagonal of the quadrilateral cross section facing up and down, all the rice husks C remaining on the upper part also slide down, and the spouts 4 and 4 and the upper end openings 41 and 4 41, the opening edge that opens in the shape of a funnel coincides with the bottom opening edge of the container part 5, and also at the joint between the opening edges of the spraying ports 4 and 4, has a triangular top shape, All of the rice husks C will fall.

    In this way, the rice husk spraying device 1 that has finished spraying is lowered from the tractor to the ground, and then the container unit 5 is removed and folded, and the fence-type skeleton units 21, 21,. .... can be removed and disassembled or folded so that it can be made quite small. Further, since the obstructing members 6 and 6 are arranged so as not to protrude from the upper surface of the bottom frame 3, they do not get in the way during transportation and storage.

    Further, when the obstructing members 6 and 6 are structured as shown in FIGS. 4 and 5, the rice husk spraying apparatus 1 can similarly promote smooth discharge of the rice husk C and prevent clogging. When disassembling, the obstructing members 6 and 6 themselves are removed from the bottom frame 3 or folded to fold into the spraying ports 4 and 4 in the side cross-sectional shape of the bottom frame 3 or the storage space around the bottom frame 3. Or can be handled so as not to be bulky with the fence-type skeleton parts 21, 21,.

    In addition, when the opening / closing shutters 43 and 43 having the structure shown in FIG. 6 are provided, when the spray ports 4 and 4 are closed, the backward end when the opening and closing shutters 43 and 43 are opened faces upward. The rollers 43a and 43a are urged to come into contact with the lower edge portions of the lower end openings 42 and 42 to eliminate a gap between the open / close shutters 43 and 43 and the lower edge portions 42 and 42. In addition, when the open / close shutters 43 and 43 are opened by being moved backward in the horizontal direction as indicated by chain lines in the figure, the open / close shutters 43 and 43 are prevented. Since the end in the backward direction is urged upward by the urging means (not shown), the rollers 43a and 43a are in contact with the funnel-shaped lower side wall surface that continues from the lower end opening 42 to the upper end opening 41. Maintain and spray When the rice husk is prevented from entering between the lower end openings 42, 42 of the 4, 4 and the upper surfaces of the open / close shutters 43, 43, the clogging is eliminated and the spraying ports 4, 4 are closed again. The open / close shutters 43 and 43 are prevented from becoming unable to slide due to clogging of the rice husks.

    As in the case of the open / close shutters 43, 43 shown in FIG. 7, if the inclined shutter surface having a predetermined gradient is formed so as to gradually increase from the forward direction end when closing to the backward direction end when opening, When the opening and closing shutters 43 and 43 are slid from the state in which the spraying ports 4 and 4 are closed as indicated by the solid line to the state in which the spraying ports 4 and 4 are opened as indicated by the chain line, the spraying port 4 The gap between the lower end opening 42 and the upper surface of the opening / closing shutter 43 gradually increases as the slide moves, preventing clogging of the rice husks in the gap, and the opening / closing shutters 43, 43 are indicated by solid lines. As shown in the figure, when closing again, the husk with the inclined upper surface of the sliding opening / closing shutter 43 between the lower end opening 42 of the spraying port 4 and the upper surface of the opening / closing shutter 43 is replaced with the spraying port. Since push back to discharge to the side, and it can prevent a situation in which it becomes impossible closure.

    The open / close shutters 43 and 43 shown in FIG. 8 prevent clogging of the open / close shutter 43 at the lower end edge of the lower end opening 42 of the spray port 4 when the spray ports 4 and 4 are closed as indicated by solid lines in FIG. The upper end of the piece 43b is elastically abutted to form a hermetic seal, which eliminates the clogging of the rice husk and prevents clogging. The opening and closing shutters 43 and 43 are slid in the backward direction to open the spray port 4. In this case, the clogging prevention piece 43b that protrudes upward is moved backward to enlarge the gap between the lower end edge of the lower end opening 42 of the spray port 4 and the upper surface of the open / close shutter 43, When the open / close shutters 43 and 43 are moved forward and closed again, the clogging prevention piece 43b that moves forward is opened and closed. Sha The husks on the upper surface of the compressor 43 are moved and discharged from the vicinity of the lower end edge of the lower end opening 42 to the center side of the spraying port 4 to prevent the occurrence of the phenomenon of being unable to close due to clogging. The upper ends of the clogging prevention pieces 43b, 43b elastically contact the lower end edges of the lower end openings 42, 42, and the open / close shutters 43, 43 can be smoothly slid and moved until the spray ports 4, 4 are completely closed. To be.

(Effects of Example Invention)
As described above, according to the rice husk spraying apparatus of the present invention, a large amount of rice husk generated by rice hulls is directly accommodated in the container portion, transported to the field as it is, and tractor capable of traveling in the field It can be connected to or mounted on a truck, trailer or truck, etc., and an appropriate amount of rice husk can be discharged and sprayed from the spraying port by operating the opening and closing shutters as appropriate. Horizontally across the flat cross section near the center of the spout flat section at a suitable location above the lower end opening of the spout and within the funnel cross section or just outside the funnel cross section just above the top opening. By means of the obstructing member arranged in the form of a frame, the vessel-shaped shell itself, straw, or mixed rice straw twigs, etc., mesh with each other immediately before being discharged from the spraying port to form a linked pile structure. Because it is partly isolated and divided, the rice husks do not become clumps like conventional ones, but they continuously collapse and can be released smoothly and without delay, stopping the release The excellent feature is that it is possible to eliminate the interruption of the spraying work due to and to make it possible to realize the efficient and homogeneous spraying of rice husks in the field.

    In particular, the rice husk spraying apparatus 1 described in the embodiment has a skeleton body 2 formed by a combination of the fence-type skeleton parts 21, 21,... 2 is a relatively lightweight structure with a net or vinyl sheet container section 5 stretched inside 2 so that it can be used for soft rice fields and fields even when a large number of ridges are mounted. It is also convenient for entering, and after use, the disassembled container part 5 and the fence-type skeleton parts 21, 21, ... can be folded, downsized, transported and stored, depending on the small number of people As shown in FIGS. 1 and 2, the obstruction members 6 and 6 are arranged so as to be within the range of the cross-sectional shape of the bottom frame 3 as shown in FIG. 1 and FIG. The obstruction members 6 and 6 do not get in the way when transporting and storing Deformation and breakage due to contact with other prepared objects can be prevented in advance, and the inhibitor members 6 and 6 provided so as to protrude upward are removed as shown in the bottom frame 3 shown in FIG.

    Further, according to the rice husk spraying device included in the present invention, the end of the opening / closing shutter in the direction of the open movement is formed at a higher position than the end of the direction of the closing movement, When closing and opening the spray port, it is possible to reliably prevent clogging of the rice husk between the lower edge of the lower end opening and the upper surface of the open / close shutter. Even when closing the open / close shutter while remaining, make sure that the open / close shutter can be closed, such as the occurrence of concentrated spraying to one place due to poor closing of the open / close shutter, or the scattering of the rice husk by the scoop Even if you open and close the open / close shutter several times until you finish the disassembly work and spray all the amount of rice husk in the container, Without raw, it becomes a homogeneous sprayed effect was soo that it is possible to respect the field to the end is obtained.

    The opening / closing shutters 43 and 43 shown in FIG. 6 described in the embodiment are assumed to be urged upward in the backward direction when opened, and further provided with rollers 43a and 43a at the backward direction end. The gap between the lower edge of the lower end openings 42, 42 and the opening / closing shutters 43, 43 is minimized to prevent clogging of the rice husks, and the opening / closing operations of the opening / closing shutters 43, 43 are always stable and reliable. In addition, the open / close shutters 43 and 43 in FIG. 7 are inclined surface shapes having a predetermined gradient so as to gradually increase from the forward direction end when closing to the backward direction end when opening. The gap between the lower end opening 42 of the spraying port 4 and the upper surface of the opening / closing shutter 43 is enlarged along with the opening movement at the time of opening, and the chaff is placed on the side of the spraying port 4 at the time of closing. Push back to clog To prevent Ri, the effect of the non-openable and closing impossible to become a situation can be reliably avoided can be expected.

    Further, in the case of the opening and closing shutters 43 and 43 shown in FIG. 8, when the clogging prevention pieces 43 b and 43 b protruding upward at the end of the closing movement direction close the opening and closing shutters 43 and 43, When the gap between the lower edge portion is closed and the open / close shutters 43 and 43 are opened, the clogging prevention pieces 43b and 43b slide to the lower side of the bottom frame 3 to open the lower end opening. The gap between the lower edge portion of 42 and the upper surface of the opening / closing shutter 43 is enlarged, the clogging of the rice husk is surely prevented, and the opening / closing shutters 43, 43 can be opened and closed smoothly.

    As described above, the rice husk spraying device of the present invention can achieve the intended purpose evenly by its new configuration, and greatly increases the number of parts compared to the conventional rice husk spraying system. Since it is realized by a relatively simple structure and is easy to manufacture, it can be manufactured and sold at a relatively low price without raising the price. A series of operations up to transportation and spraying can be made much more efficient than conventional techniques, making farming work more efficient for farmers who have problems such as labor shortages and aging. The rice husks, which are generated in large quantities every year and are difficult to treat, are used as an effective organic material for enriching field soil nutrients, and the use of chemical fertilizer is reduced or eliminated as much as possible. Reduction of rice production and production of good rice, as well as rice farmers who are very interested in rice husk spraying to the field, as well as being highly evaluated in the agricultural equipment industry, It is expected to become popular.
