[Prior art]

 Japan's rice farming is affected by the gradual import deregulation of foreign rice and liberalization of rice sales due to recent deregulations, and there is a strong demand to further improve quality and strengthen price competitiveness. Is coming of age. Against this background of difficult times, it can be seen that rice farmers collect and treat the paddy rice, which had been harvested and treated for each individual household, at a large rice center constructed through joint investment with government support and joint treatment. Thus, the proactive implementation of major management improvement measures is being promoted. Such rationalization measures are also required for the means of bringing the rice grains into large rice centers, and the rice grains packed in combine bags (30 kg) are loaded separately in light trucks and transferred from the combine harvester. A method has been adopted in which the harvested paddy rice is directly received on the truck bed, and a large amount of paddy rice is transported and delivered at one time. For this reason, there are various transport containers that can load as much rice as possible onto the loading platform of a light truck.

As shown in the front cross-sectional view of FIG. 10, the transport container 31 has an iron plate inside a rectangular frame-shaped steel skeleton body 31 a that is erected at the four corners of the loading platform 2 a of the light truck 2. In most cases, a box-shaped container having a substantially rectangular shape is attached and fixed with a veneer plate or the like, and the whole upper part is opened to form an opening 31b, and a powder of paddy rice or the like supplied from a combine (not shown). It has a structure for receiving the particles 3. At the lower center of the box-shaped container, there is formed a flow-down section 31c having a funnel-shaped inverted triangular cross section, and a screw conveyor 31d having an axial center in the front-rear direction is formed at the lowest section. The screw conveyor 31d is integrally incorporated and rotated and driven by the operation of a drive source such as a motor (not shown) so that the powder particles 3 packed inside can be delivered toward the rear end side of the loading platform 2a. Is configured.

The transfer by the transfer container 31 has an effect of remarkably improving the work efficiency as compared with the method which has been carried out by manually loading the packed rice in a truck by hand. However, since the discharge by the screw conveyor 31d is adopted, the flow-down portion 31c is indispensable on the bottom side of the transport container 31, and the space 32 that is never used is formed wastefully below the outer side of the transport container 31. In addition, the amount of paddy rice that can be stored on the light truck carrier 2a cannot be increased to a certain extent or more, and if the total height of the transport container 31 is increased in order to increase the total load, it is higher than the wasteful space. As the number of loaded items increased, the position of the center of gravity became higher, resulting in a fatal defect that the running stability was significantly impaired.

Therefore, as a container that takes measures to avoid the height of the center of gravity, for example, a transport container 41 as shown in the front sectional view of another conventional example shown in FIG. 11 has been proposed. . This improved transport container 41 is a box-shaped container in which a metal plate material is attached to and integrated with a rectangular frame-shaped skeleton body 31a fixed on a loading platform 2a of a light truck 2 and an upper side surface is opened. None, while the screw conveyor 31d is arranged in the center of the bottom with the shaft center in the front-back direction, while the ends on the left and right sides of the screw conveyor 31d are in close contact with the periphery of the granular material intake port on the upper surface of the screw conveyor 31d. A plurality of compression springs 41b, 41b having a predetermined strength are provided on the back side of both the tilt bottom plates 41a, 41a. , Are arranged so as to be balanced left and right.

In this type of transfer container 41, the tilt bottom plates 41a, 41a are compressed springs 41b, 41b by the weight of the paddy rice as the rice is put into the transfer container 41 to increase its amount. , ..., both tilting bottom plates 41a, 41a start to descend naturally, and when fully loaded, they become horizontal as shown by the broken line and become a substantially complete box type container, which is an efficient container for storing paddy rice. It is possible to move to the ground, and when it arrives at the transportation site, the screw conveyor 31d is activated to start discharging the paddy rice to the rear of the loading platform 2a, and the amount of the paddy rice in the transport container 41 is gradually reduced to reduce the internal weight. Then, the tilt bottom plates 41a, 41a are gradually inclined toward both ends by the springs 41b, 41b, ... In other words, it has a ship bottom structure, and the unhulled rice around the corners naturally flows down toward the screw conveyor 31d and is discharged by the screw conveyor 31d.

In the case of this improved transport container 41, it is possible to avoid the disadvantages of the transport container 31 shown in FIG. 10 up to that point, and to efficiently load grains such as paddy rice with a lower center of gravity. However, in order to make the joint portions of the left and right tip edges of the tilt bottom plates 41a, 41a and the inner wall surface of the main body of the conveying container 41 abuttable and slidable with each other, the tilt bottom plate 41a , 41a has a middle-folded structure, and high-performance compression springs 41b, 41b, ... with little settling must be prepared, so they are expensive and are not suitable as containers that are used only at the time of harvest. That is, the perfect contact between the left and right tip edges of the tilt bottom plates 41a, 41a and the inner wall surface of the main body of the transport container 41 is maintained to prevent leakage of paddy rice from the same place or to prevent the rice from being pinched. hand It suffers from structural functional problems such as difficulty in avoiding problems that interfere with the sliding function, and so far it seems that it has not been widely spread or expanded. is there.

In addition, most of these conventional box-type transport containers 31 or 41 employ an integral box-type structure from the viewpoint of leakage prevention, and are extremely bulky and heavy. However, not only does it have the basic problem that it is not suitable as a container for light-duty vehicles such as light trucks, but it also hinders driving under bad road conditions around paddy fields. In addition to the practical inconvenience, it requires a special device such as a crane for loading and unloading the loading platform 2a of the light truck 2, which is necessary before and after use as a container. However, the inconvenience of having to occupy a considerable amount of space for storage and management for a long period of time also placed a heavy burden on the farmers who adopted it.

In view of the above situation, the inventor of the present application has attempted to reduce the weight and make the attachment and detachment to and from the vehicle body as easy as possible, and furthermore, the assembly and disassembly are easy and the storage and management are hindered. In addition, it is possible to provide it as an inexpensive device that meets the condition that it is used within a very limited period of time, and in addition, it is possible to carry out extremely efficient storage and discharge of granular material. As a result of having started the realization of a truck-mounted powder and granular material transport container that has a substantially ideal structural function as this kind of container and continuing repeated trials and experiments, finally here, We have succeeded in developing and completing a transport container having a new and useful structure that can substantially satisfy those requirements. Below, we will describe the configuration of the transport container with a representative embodiment of the present invention shown in the drawings. What to say And

[0010]

[Constitution of device]

 As can be clearly understood from the representative embodiment shown in the drawings, the truck-mounted powder and granular material transport container of the present invention basically has the following configuration. That is, a large bag made of a flexible material having a structure that fits into the inside of the skeleton in a substantially splicing state is inserted into the skeleton of a predetermined height that can be mounted on a truck bed. A screw that detachably supports the upper edge of the large bag on the upper horizontal aggregate of the skeleton, and arranges the periphery of the discharge portion opened at the bottom of the large bag in a substantially horizontal shape on the truck bed. While it is attached tightly to the periphery of the upper surface of the conveyor for the powder and granular material, on the other hand, on the outer surface in the vicinity of the bottom of the large bag and parallel to the discharge part at the bottom, there is a hanging ring part with a straight threading structure. By raising the hanging rod, which is integrally formed and inserted through the hanging ring portion, to a predetermined height position by a suitable means, the large bag portion from the hanging ring portion to the discharge portion is formed into powder particles of the screw conveyor. Toward a body intake, gradually approaching a straight line inclined surface of about 45 degrees or more The track mounting granular material transport container which allows to continue to deform.

[0012] Further, when the truck-mounted granular material transfer container of the present invention having the above-described basic configuration is shown as a configuration according to a preferred embodiment, it can be erected in a plane arrangement that can be mounted on a truck carrier. A skeleton body having a predetermined height and extending substantially in the inside of the skeleton body so as to extend sufficiently, and the bottom portion of the skeleton body is arranged directly on the truck carrier or in a substantially horizontal manner on the truck carrier. A large bag made of a flexible material that is placed on the bottom plate and adapted to fit naturally is assembled into an insertion shape, and the upper edge of the large bag is placed over the upper end of the skeleton. In addition to being detachably supported by the aggregate, the peripheral edge of the discharge part opened in a straight line in the front-back direction of the truck bed with a predetermined width at the center of the width direction of the bottom of the large bag has a substantially horizontal shape in the center of the truck bed width direction. There is powder While closely attached to the periphery of the granular material intake on the upper surface of the screw conveyor where the delivery port is arranged toward the rear of the truck bed, it is parallel to the discharge part provided on the bottom near the bottom of the large bag, In addition, a hanging ring portion having a straight through-hole structure is integrally formed on each of the outer side surfaces which are separated from the discharging portion by a predetermined distance, and the respective hanging rods respectively inserted through these hanging ring portions are appropriately inserted. The large bag portion from both suspension ring portions to the discharge portion is raised substantially at the same time by means of a means so that the large-scale bag portion extends toward the powder / granule intake port of the screw conveyor at an angle of approximately 45 degrees or more. It can also be shown as a truck-mounted powder and granular material transport container that can be transformed into a.

The skeleton body is a plane arrangement that can be mounted on a truck bed, and is made of a strong rod-shaped member such as a steel pipe or an angle member that has a height that does not hinder the running of the truck. It is equipped with at least four columns that stand upright with the truck carrier as a support section, and upper-end cross-linking aggregates that connect their heads. It will be extremely convenient if each block can be assembled and disassembled and that it is formed so that it can be easily assembled and disassembled even on the truck bed. It should be noted that means for increasing the structural strength of this skeleton, for example, means for arranging plates, braces or other reinforcing auxiliary materials at corners, assembling joints and other places can be adopted as needed. Needless to say.

On the upper end horizontal aggregate of this skeleton, appropriate means for hooking the upper edge of the large bag described later, that is, the upper edge structure of the large bag is formed at, for example, a required position. If the eyelet is used as the attachment part, a hook for hooking the eyelet may be provided so as to project at a required place, or a laterally passing bag part, band, band, etc. may be formed. If it is a skeletal body, keep it as a mere rod-shaped body and hang it by inserting it horizontally when assembling the skeleton and assembling it, or by wrapping the band around the upper end horizontal aggregate of the assembled skeleton body. It suffices that a publicly known means such as stopping is adopted as appropriate, and the structure adopted as a hooking step does not particularly relate to the gist of the present invention.

The large bag body is formed of a flexible sheet or cloth body which has already been adopted as a combine bag, a rice bag or the like, and has a skeleton with the above-mentioned skeleton body upper-end horizontal aggregate as a supporting portion. It spreads over the inside of the body and is stored in a suspended form, which functions to store powdered rice and other granular material that is input from the top opening as efficiently as possible. A discharge part that is long in the front-rear direction and opens in a substantially straight line with a predetermined width is formed, and the periphery of the discharge part is aligned with the discharge part on the top of the screw conveyor on the loading platform. It is attached tightly. It is most desirable that the discharge port forming portion at the bottom of the large bag body is formed at a position corresponding to the central portion of the bottom truck carrier width, but the location is not necessarily limited to this, and the truck carrier is not limited thereto. There is no problem if it is formed on either side of the width direction of the truck, and in that case, the location of the screw conveyor should be placed substantially horizontally on the truck bed according to its position. Becomes

On the other hand, on the outside of the large bag, which is parallel to the axis of the screw conveyor, a means for raising the same horizontal portion within the entire width of the surface is combined, and by the raising operation of that portion, , So that an inclined surface of at least about 45 ° is finally formed on a substantially straight line from the same action point toward the powder / granule intake side on the upper surface of the screw conveyor. For example, in the structure shown in Examples described later. In addition to the above, a structure in which a reinforcing material is sewn into the outside of the large bag in advance is sewn in, and a plurality of loop-shaped suspension rings attached to the required points of the reinforcing material are sewn. The structure should be such that it should be rolled up and lifted with a hanging string. It should be noted that the location where this is raised is not limited to both sides on the outside of the large bag, but is as described above.The location where the discharge port at the bottom of the large bag is formed is offset to either side of the width of the truck bed. In such a case, the outer surface of the large bag that needs to be raised is only the outer surface opposite to the side on which the discharge port is formed (however, in this case, the discharge port formation location on the bottom of the large bag body). However, it is needless to say that the pulling height is more than doubled compared to the case where it is arranged in the widthwise center of the truck bed and both outer surfaces are raised).

[0016] To raise the predetermined position of the large bag described above, the drum attached to the take-up shaft is wound up with a pulling rope such as a rope, a wire or a chain whose end is connected to an appropriate place outside the large bag. The structure is as shown in the examples below, or a pull-up rope such as a rope with the end connected to the outside of the large bag is placed with a return pulley etc. in place. The pulling rope is to be pulled up by appropriate raising means, such as a structure in which the end side of the pulling rope can be pulled up in a substantially vertical direction by changing the direction with a return pulley and pulling. , Such that they can be operated manually by rotating the handle, by combining appropriate gears such as claw gears, with an intervening transmission mechanism, or with a power source such as a winch. It is possible to adopt known appropriate means, such as one that operates, or one that automatically drives by using the driving force of the motor that drives the screw conveyor. In cases where it is necessary to pull up by a certain amount, cases in which the pulling up amount must be different on both outer surfaces, and when only one outer surface needs to be pulled up, a screw conveyor to the bottom of a large bag body The lifting mechanism should be optimized according to the combination structure of. Hereinafter, the configuration of the present invention will be described in detail together with the representative embodiment of the present invention shown in the drawings.

[Work]

 The truck-mounted powder and granular material transport container of the present invention having the above-described structure includes the skeleton body 4 and the large bag body 1 shown in FIGS. 1 and 2, and the lifting belts 6a and 6a shown in FIG. The shape of the large bag 1 can be freely changed to the state shown in the front cross-sectional view showing the unwound state of the ..., and the state shown in the front cross-section showing the winding state of the lifting belts 6a, 6a ,. When the lifting belts 6a, 6a, ... Are released, the hanging rods 6c, 6c descend to near the floor surface of the loading platform 2a, and the large bag 1 moves around the screw conveyor 5 and the bottom of the loading platform 2a. It is possible to flexibly deform along the shape to maximize the internal capacity, and when the lifting belts 6a, 6a, ... At the bottom of the screw conveyor 5 The portion from the peripheral edge 5b to the suspension ring portions 1b, 1b, ... Is transformed into a linear inclined surface inclined at an angle of approximately 45 degrees or more, and powder particles (not shown) remaining on the bottom corner side of the large bag 1 are removed. It is made to flow down to the screw conveyor 5 side so that it can be completely discharged.

Therefore, first, the maximum amount of internal capacity of the container for transporting powder and granules of the present invention, in which the paddy rice harvested by the combine is mounted on the loading platform 2a of the light truck 2 parked on the farm road, After it is packed in a large bag 1 that has been expanded to a full size, it is moved to a hulling work place such as a rice center, and as shown in the front sectional view showing the discharging work state of the granular material 3 in FIG. When the screw conveyor 5 is driven by a motor (not shown) and the discharging work of the granular material 3 such as paddy rice to the rear of the loading platform 2a is started, the granular material 3 is positioned around the upper part of the screw conveyor 5. The particles are sequentially discharged, but when the amount is gradually reduced, the granular material 3 around the corner of the large bag 1 remains without being delivered.

Therefore, by rotating the handle 7b shown in FIG. 1, the drums 6b, 6b, ... Are rotationally driven in the direction of the arrow shown in the front sectional view showing the discharging operation state of FIG. The belts 6a, 6a, ... Are wound up and the suspension rods 6c, 6c are raised, and the suspension ring portions 1b, 1b ,. When the portion up to 5b is linearly inclined, the granular material such as paddy rice around the corners begins to flow down toward the granular material intake of the screw conveyor 5 and finally reaches about 45 degrees or more. By forming an inclined surface on a straight line inclined at an angle, all of the powder particles 3 on the corner side are discharged to the conveyor 5 side. Meanwhile, at the final inclination angle, the rotation of the handle 7b is stopped by a braking device (not shown). Then, when all the powder particles 3 have been discharged and the large bag body 1 becomes empty as shown in FIG. 4, the braking device is released to rotate the handle 7b in the releasing direction. The suspension rods 6c, 6c are lowered to bring the powdery or granular material 3 into a state of being loaded again, as shown in FIG.

On the other hand, in the case of the truck-mounted powder and granular material transport container shown in the second embodiment, the electric motor 23 is activated, the screw conveyor 5 is rotated, and the powder and granular materials fed to the surroundings are first fed. When the body 3 is discharged, and when the amount of discharge gradually starts decreasing, the operating rod 25b of the braking mechanism is retracted, and the engagement between the hook wheel 25 and the braking piece 25a in FIG. 9 is released. Moreover, the driving of the belt mechanism is started by operating the operation lever 23d so as to maintain the tension applied to the drive belt 23c, and the rotational torque is changed to the left or right via the first and second driven grooved wheels 23b and 24b. When it is transmitted to the driven shafts 24, 24 of the driven shafts 24, 24, the driven shafts 24, 24 take up the lifting belts 6a, 6a, ... From the state of FIG. 6 to the state of FIG. Automatically by large bag The left and right sides of the body 1 are lifted, the bottom side of the large bag 1 is deformed into a linear inclined surface, and the powder particles 3 around the corners are made to flow down toward the screw conveyor 5.

When the bottom angle of the large bag 1 is maintained in the state shown in FIG. 7, the operating rod 25b of the braking mechanism shown in FIG. 9 is pushed in to engage the braking piece 25 with the hook wheel 25. By stopping the rotational drive of the first driven grooved wheel 23b, stopping the operation of the operation lever 23d to remove the tension of the drive belt 23c, and stopping the torque transmission function, as shown in FIGS. The angle of the linear inclined surface on the bottom side of the large bag 1 shown in 4 can be maintained at a predetermined angle. Therefore, when the final setting at an angle of about 45 ° or more is completed, the discharge of all the powder particles 3 inside the large bag 1 is completed. After all the powder particles 3 have been sent out, the operating rod 25a is retracted and the braking of the hook wheel 25 is released, so that the suspension rods 6c, 6c are automatically lowered by their own weight, and again as shown in FIG. The powdery or granular material 3 is restored to the maximum capacity. At this time, the operation lever 23d is not operated, and the drive belt 23c is in a state where the tension is lost.

[Effect]

 As shown in the front sectional view showing the state in which the powder particles 3 are fully loaded in FIG. 5, the large bag body 1 in which the hanging belts 6a, 6a, ... The powder granules 3 can be tightly inserted into the peripheral portion of the screw conveyor 5, which is a space that cannot be effectively used with a large metal bag, and can be used as a mounting space. As described above, the transport container for powder and granular material of the present invention, first and foremost, has a weight of about 2 as compared with the conventional metal transport container because the transport container is composed of a large bag. It can be reduced to / 3 or less to significantly reduce the weight, enhances the running stability of the truck, and has a large bag that is flexible, so that it cannot be effectively used in the conventional structure. The space behind the sloping surface flexibly accommodates the space on both sides of the screw conveyor, and is deformed to effectively expand the storage space to allow maximum storage of powder and granules. It must be emphasized that it has a very outstanding feature that it gradually raises and slopes the side so that finally all the particulate matter can be discharged to the outside by the screw conveyor. I have to.

As a result, the loading efficiency can be maximized, and the low center of gravity, which could not be achieved by the conventional transport container, can be achieved. In addition to the advantage of making a great contribution to the improvement, the structural and material characteristics of the material not only make it possible to significantly reduce the material cost and the manufacturing cost, but also the transportation cost and the inventory management. Fortunately, the product cost can be significantly reduced compared to other products of this type before, which reduces the burden on the user and makes it a container for paddy rice especially for farmers. It can be said that its usefulness will be extremely high as it is only used for about 10 days throughout the year, as in some cases.

Further, in the example shown in Example 1, the above-mentioned characteristics are more remarkably exhibited, the operability is easy, and it is possible to make it extremely economical. It can be a very useful container for rice paddies for farmers, and according to the second embodiment, it is necessary to rely on elderly people and women who are relatively weak, such as a part-time farmer. It can be said that it will be the best container for the lost farmers.

As described above, the container for transporting powder particles of the present invention is easy to manufacture and can be provided at a low cost, and is excellent in handleability such as assembling / disassembling, storing / managing, and the like. Since it enables safe and efficient transport of the body, it is extremely useful as a transport container for various types of powder and granules, as well as for transporting paddy rice in the rice farming industry. It is expected that the demand for
