Description

  The present invention assembles a hollow cubic frame that can be mounted on a truck bed with a metal material, and suspends and attaches a grain bag having a bottom formed in a funnel shape with a sheet of synthetic resin material. It is related with the improvement about the container for the grain conveyance which comprises.

  As shown in FIG. 1, a container for carrying a grain of the above-described form is usually formed on a loading platform t of a truck T by a pillar material / girder material formed into a rectangular tube shape by bending a metal plate such as an iron plate. The lower ends of the frame pillars 2 formed separately are inserted into the respective upper ends of the base pillars 10 at the four corners of the short square frame-like base 1 having a floor area that can be mounted on the base plate, and screws are used. Connected, the frame pillars 2 at the four corners are erected, and the ends of the beams a serving as girders are respectively provided on the two upper surfaces of the frame pillars 2 facing the adjacent frame pillars 2. A short tubular connecting fitting 3 to be fitted and connected is installed, and the end of the beam a that is bridged as a girder between the adjacent frame pillars 2 is inserted into and connected to the connecting fitting 3. 1 is assembled into a square cubic hollow frame A.

  As shown in FIG. 2, short joint columns 4 that are separately formed are respectively inserted into the upper ends of the frame pillars 2 at the four corners of the frame body A, and the adjustment of the protruding length thereof is freely connected. Then, on the two surfaces opposite to the joint pillars 4 adjacent to the joint pillars 4, the connection fittings 3 configured in the same manner as the above-described connection fittings 3 are provided, and the upper opening of the grain bag B is provided in this. In order to hold the opening edge of the beam a in an open state, the end of the beam a formed in the same manner as the beam a described above is supported.

  The grain bag B suspended in the lumen of the frame body A is a substantially rectangular rectangular tube with four sides of the front, back, left, and right by a sheet or fabric made of a synthetic resin material, and the bottom side has four sides. Is formed into a funnel-like shape gradually narrowing toward the bottom, and a sheath-bag-like tube portion 60 into which the beam a is fitted on the outer surface side of each upper surface formed in a square tube shape. Are formed in parallel with each other in multiple stages, and the bottom of the bag B formed at the lower end on the bottom side in the form of a funnel has a substantially rectangular frame made of an iron plate as shown in FIG. The metallic mouth frame 61 is assembled and fixed with screws 62.

  And mounting | wearing which makes this grain bag B suspended with respect to the frame A attaches the frame-shaped mouth frame 61 provided in the lower mouth of the grain bag B to the upper surface of the base 1 of the frame A. Assemble and set with screws to the assembly seat 11 provided in the central part, and insert the beam a into the sheath-bag-shaped cylindrical portion 60 provided on the outer surface of each surface on the upper side of the grain bag B. The upper side of the grain bag B is lifted together with the beam a, and both end portions of the beam a protruding from the sheath bag-like cylindrical portion 60 are fitted into the connection fitting 3 provided at the upper end of the joint column 4 and are fastened. I'm trying to do it.

  When the grain bag B is suspended from the frame A, the selection when inserting the beam a into the sheath-bag-like cylindrical portion 60 arranged in parallel is performed by placing the frame A on the truck bed. According to the relationship with the height of the barn entrance when the grain is transported by running the truck, the cylindrical portion 60 at the corresponding height position is selected from the set projection height of the joint pillar 4.

  As shown in FIG. 1, the grain transporting operation performed using the grain transporting container C configured as described above is performed by placing the frame A with the grain bag B suspended on the loading platform of the truck T. A grain that is placed next to the combine that is being harvested in the field by driving the truck T, and the grain released from the harvesting cylinder of the combine is suspended on the frame A The bag B is received from the opening on the upper surface side and is transported to the position next to the grain dryer installed in the storage building by the running of the truck T. The receiving port is connected to the opening of the lower side of the frame-shaped mouth frame 61 attached to the lower mouth of the grain bag B, and can be swung freely along a horizontal surface at the center of the opening. The grain transport cylinder 70 is connected to the assembled grain transport machine 7 and connected by the operation thereof. The grain is transported by the grain transport cylinder 70, and it is used so as to be put into the tension hopper of the grain dryer and stuck in the machine of the grain dryer. The dried grain is received in a grain bag B suspended on the frame A and used to be transported to a grain storage facility by driving the truck T.

  The grain transport container used in this way is used only during the harvest period when the grain is harvested. When the season is over, the container is folded and stored in the storage building.

  At this time, the container C for transporting the grain is folded by four beams a inserted through the cylindrical portion 60 provided at the opening edge of the grain bag B suspended on the frame A. Pull out and release the suspension of the grain bag B, then remove the four beams a that are spanned as girders between the frame pillars 2 at the four corners of the frame A, and then remove the frame pillars 2 at the four corners. Pull the frame body A into the base 1, the frame pillar 2, and the eight beams a, and the grain bag on the upper surface of the base 1 to which the grain transporter 7 from which the grain transport cylinder 70 is pulled out is assembled. B is folded, and the frame pillar 2 and the eight beams a which are separated from each other are overlapped, and are fastened with a string to finish the folding work and store it in the storage building.

  This container for transporting the grain is troublesome and troublesome to carry out the folding work in which the eight beams are removed from the frame and the grain bag when the grain is stored when it is not in use. There is a problem. In particular, the removal of the four beams a, which are used as girders, from the frame column 2 involves a troublesome task of removing the set screw.

  The problem to be solved in the present invention is to simplify the folding work when storing the two frame frames adjacent to each other by pairing the frame pillars at the four corners of the frame body in front and rear or left and right. The pillars become a pair of frame pillars that are integrally joined together, and the pair of frame pillars that face the pair are opposed to each other such that they face each other in the front-rear or left-right direction. When it is assembled to the base so that it can rotate freely toward the base and is folded on the base by the rotation of the lodging, the folding can be performed with the grain bag suspended, and the suspended grain The four beams for holding the opening on the upper surface side of the granule bag in an open state are combined with the four beams of the girders spanned between the frame pillars at the four corners in order to construct the frame, When halving the number of beams, Assembly rack-is, without using the set screw is to make it perform in a state where allowed sufficient holding strength of the frame body to construct.

As a means for solving the above-described problems, in the present invention, as described in claim 1, on each upper end side of the base pillar 10 at the four corners of the base 1 assembled into a square frame with a low profile, A striking beam in which the lower end side of the frame column 2 is connected via a hinge 12 so as to freely rotate in the direction toward the upper surface of the base 1, and is detachably suspended between the frame column 2 and the base 1. The upper ends of the frame columns 2 are connected to the lower ends of the joint columns 4 by fitting the projecting heights to the upper ends of the frame columns 2, respectively. On the side, a metal plate that fits and connects the ends of the beam a spanned between adjacent joint posts 4 is formed into a channel shape into which the end of the beam a is fitted into the inner cavity. 3, as the posture of the open side of the peripheral wall of the fitting 3 is directed upward, the small of the peripheral wall of the Tsugihashira fourth wall Fixedly attached by butting welding to each other, and provided on the inner surface of the peripheral wall of each connection fitting 3 and formed on the peripheral wall of the beam a on the inner surface of the bottom wall 30 facing the open side The locking pin 32 that fits into the hole b is planted in a posture that protrudes upright from the inner surface of the bottom wall 30 toward the open side, and is fitted into the connection fitting 3 at the end edge of the open side. A holding piece 33 made of a spring material for holding the combined beam a is provided so that the beam a can be assembled to the connection fitting 3 by fitting the beam a. A beam a is passed between adjacent ones of each other to assemble a cubic frame A, and the frame A is a rectangular tube with a square upper portion made of a synthetic resin sheet or cloth. lower portion side is formed to be a shape of funnel-shaped, rectangular tube-shaped upper side in The grain bag B has only set the sheath bag-shaped cylindrical portion 60 which occupies allowed fitting the pre Symbol beam a before and after the left and right surfaces in side, of four to cathodic between Tsugihashira 4 of the frame A Each of the beams “a” is inserted into the cylindrical portion 60 of the grain bag B to suspend the grain container B.

  The container for carrying grain according to the present invention comprises a beam a which is a beam material for connecting and holding frame pillars 2... Standing at the four corners of the base 1 of the frame A so as to assemble and configure the frame A, and a suspension. In order to keep the opening on the upper surface side of the grain bag B to be opened, the upper end of the frame column 2 is inserted into a sheath-bag-shaped cylindrical portion 60 installed on the outer surface side of the opening edge of the grain bag. The four beams a, which are used as the beam a spanned between the connecting pillars 4 connected to the side so that the height can be freely adjusted, and are inserted into the cylindrical portion 60 are provided between the pair of frame pillars 2. The other two beams a are extracted by leaving the two beams a to be passed through the cylindrical portion 60 and being connected to the connection fitting 3 provided on the upper portion of the connecting column 4. In this state, the frame A is folded by folding the pair of frame pillars 2 to the opposite side, so that the two beams a are removed. The frame A can be folded by itself, and the connection fitting 3 for linking the beam a to the frame column 2 has sufficient strength as a fitting type that does not use a set screw. Because it can be easily removed, the folding work can be done very easily.

Along with the frame columns 2a and 2b on the front side and the frame columns 2c and 2d on the rear side that are combined, they are folded on the upper surface of the base 1.

  At this time, the front-side frame columns 2a and 2b and the rear-side frame columns 2c and 2d are folded so that the height dimension including the connecting columns 4 connected to them is the width dimension before and after the base 1. The hinge 12 that pivotally supports the frame column 2 on the side that is folded first (the frame columns 2c and 2d on the rear side in this embodiment) when they are interfered with each other when folded. The frame pillars 2a and 2b on the side to be folded later are positioned lower than the position of the pivot hinge 12 by the width dimension in the front-rear direction of the frame pillar 2, and the frame pillars 2c Frame pillars 2a and 2b that are folded later are superposed and folded on 2d.

  Here, the process of folding this frame A will be described with reference to the illustrated embodiment. From the container C in the state shown in FIG. 7, first, the frame A is installed on both ends of the left and right sides of the frame A on both the front and rear ends of the beam a and the connecting pillar 4. The connection with the connection fitting 3 is removed, and the beam a is extracted from the sheath bag-like cylindrical portion 60 of the grain bag B and removed.

  As a result, the front and rear mouth edges of the upper side of the grain bag B are suspended and supported by the front and rear beam a, respectively, so that the middle of the front and rear of the mouth edge is provided. The state shown in FIG.

  Next, the connection between the upper end side of the striking beam 5 obliquely spanned between the frame column 2 on the rear side and the base 1 and the hanging metal fitting 50 provided on the frame column 2 is released, and the striking beam 5 8 is rotated counterclockwise in FIG. 8 about the connecting shaft 51 that rotatably connects the lower end side of the base 1 and the base 1, and is stored in the side surface of the base 1. The support of the frame pillar 2 is released, and in this state, the frame pillar 2 on the rear side is folded and rotated toward the upper surface of the base 1 to obtain the state shown in FIG.

  Next, the upper end side of the striking beam 5 slanted between the frame column 2 on the front side and the base 1 is removed from the hanging metal fitting 50 provided on the frame column 2, and the striking beam 5 is removed. Then, it is rotated clockwise around the connecting shaft 51 and stored on the side surface of the base 1, and in this state, the frame column 2 is rotated toward the upper surface of the base 1 to obtain the state shown in FIG. The folding work is finished.

  In order to assemble the frame A and suspend the grain bag B on it, the joint column 4 is inserted into the sheath bag-like tube portion 60 on the outer peripheral surface of the grain bag B and connected to the upper end side of the frame column 2. In order to facilitate the removal of the beam a when the frame A is stored, the connection fitting 3 provided on the joint post 4 so as to connect and fix the beam a spanned between them, as shown in FIG. A metal plate is formed into a channel shape in which the end of the beam a is fitted into the inner cavity, and the upper end is opened to the wall surface of the joint column 4 as shown in FIG. Alternatively, as shown in FIG. 15, one side wall surface is abutted against the wall surface on the outer surface side of the joint column 4 and welded, so that it is fixedly attached to the wall surface of the joint column 4, and on the inner surface side thereof, On the inner surface of the bottom wall 30 or the inner side wall 31 located on the inner cavity side of the frame A, the fitting hole b opened in the peripheral wall of the beam a The locking pin 32 to be fitted is planted, and the end of the beam a is fitted into the inner cavity of the channel-shaped connection fitting 3 to open the peripheral wall of the beam a. In the state in which the hole b and the locking pin 32 are fitted, the holding piece 33 made of a spring material that holds the end of the beam a into the lumen of the channel-like connection fitting 3 is connected to the channel-like connection fitting 3. When the beam a is assembled, the beam a is fitted in a state where the pressing piece 33 is expanded against the bias of the spring, and the beam a is pressed when the beam a is assembled. The expansion of the piece 33 is released, and the holding piece 33 presses the beam a into the connection fitting 3 by the bias of the spring. When the beam a is removed, the holding piece 33 is pushed and expanded to remove the beam a. a of the connection bracket 3 As performed by extracting from the cavity, thereby desorption of the beam a, and to allow quick without requiring the operation of attaching and detaching of the screw or bolt.

  The assembly of the beam a to the frame A using the channel-shaped connection fitting 3 is based on the weight of the grain in the grain bag B suspended on the frame A during the grain transportation operation. The beam a is applied to the locking pin 32 in which the fitting hole b provided in the peripheral wall of the beam a is implanted in the connection fitting 3 due to the load that pulls the beam a toward the lower side inside the frame A. It receives a moving force so as to be inserted and is pressed against the inner wall surface of the connection fitting 3, whereby the beam a is firmly connected to the connection fitting 3 and the assembly of the frame A is properly reinforced. To function as a beam.

  Further, when the transport of the grain is finished and the truck T is moved by running with an empty load, the load due to the weight of the grain in the grain bag B is not applied to the beam a. The end of the beam a comes out of the connection fitting 3. At this time, the pressing of the pressing piece 33 by the biasing of the spring prevents the fitting hole b formed in the peripheral wall of the beam a from escaping from the locking pin 32, and the beam a is connected to the connection fitting 3.
