Description

  The present invention relates to a container for storing and transporting various agricultural products such as harvested potatoes, onions, carrots, and other granular materials and chunks, in particular, with four side panels in both the inner and outer directions. The present invention relates to an open container that can be rotated and separated.

Conventionally, when various agricultural products such as potatoes, onions, and carrots are harvested, collected, and transported, a container whose size is determined according to the specifications of the industry according to the agricultural products to be stored is used. There exists a thing of the following patent document 1 as this kind of container. The container is a foldable container that can fold the vertical panels 2, 3, 4 provided on the four circumferences to the upper part of the floor 5, and has the following configuration. The front panel 2 is positioned by pins 7 and 7 which are provided on support columns 6 and 6 at both ends of the front surface of the floor 5 and are movable in the axial direction, and are assembled in contact with the floor 5. The rear panel 3 is positioned by the pins 7 and 7 of the columns 6 and 6 at both ends of the rear surface of the floor and is assembled in contact with the floor 5. The left and right side panels 4, 4 are assembled by being rotatably attached to pins 8, 8 fixed to the four columns 6, 6 by welding means.
Japanese Patent No. 2992279

  The above-described prior art containers can be stacked with the four panels folded inward, but the four panels 2, 3, 4 can be expanded outward to a substantially horizontal state. It is impossible to remove the left and right side panels 4 and 4 from the floor 5 and disassemble them. For this reason, when the side panel 4 is damaged, the disadvantage is that the damaged side panel 4 must be replaced after the pins 8 and 8 fixed to the column 6 by welding are once disassembled. However, there is a disadvantage that it is impossible and must be performed at the factory, and that all the side panels 2, 3, and 4 cannot be easily disassembled for cleaning and maintenance. Furthermore, when carrying out the work of storing agricultural products in the container, the four side panels 2, 3, 4 stand up at a predetermined height, so that the worker forcibly extends his arm every time the storage operation is performed. Or has to stand up frequently, which puts a heavy burden on the body, causing stiff shoulders and low back pain.

  The present invention has been made in view of the drawbacks of the prior art, and can accommodate four crops such as crops because the four side panels can be folded inward and can also be expanded or removed substantially horizontally. It can easily and efficiently store objects, and the four side panels can be separated from the bottom panel, so it is possible to disassemble and clean or replace damaged bottom panels and some side panels. Also, since the structure can be simplified as compared with the prior art, an open container that can reduce the manufacturing cost can be provided, and at least one side panel can be folded in two from the middle in the height direction to the outside. It is an object of the present invention to provide an open container that can efficiently store stored items and can greatly reduce the burden on the body during the operation.

  The means of the present invention according to claim 1 configured to solve the above-described problems includes: a bottom surface having a substantially square bottom; a bottom panel having a substantially planar surface; and a pair of front struts erected at both front corners of the bottom panel. And a pair of rear struts erected at both rear corners, and four side panels erected by pivotally supporting both lower ends in the width direction between the front struts, between the rear struts and between the front and rear struts; The four side panels are detachably connected to each other in a frame shape, and at least one of the four side panels protrudes from the lower side at both ends in the width direction. The other side is supported by an insertion shaft support mechanism that is formed on a pair of support columns that support the side panel and that is formed with a support groove that is inserted in a state where the locking shaft is dropped. The panel can be displaced in the axial direction in the shaft insertion holes drilled in the lower side at both ends in the width direction and each pair of struts And the four side panels can be engaged with and disengaged from each pair of support columns by being supported by an insertion shaft support mechanism including a support shaft that is removably inserted into the shaft insertion hole, and It consists of what was attached so that rotation was possible in the range of about 180 degree | times.

  According to a second aspect of the present invention, there is provided a bottom panel having a substantially rectangular plane, a pair of front struts erected at the front corners of the bottom panel, and a pair of rear stanchions erected at the rear corners. And four side panels erected by pivotally supporting the lower end sides in the width direction between the front struts, between the rear struts and between the front and rear struts, and a frame that allows the four side panels to be engaged and disengaged. The side panel is formed of a locking shaft projecting on the lower side at both ends in the width direction and a pair of struts supporting the side panel. The four side panels can be engaged with and disengaged from each pair of struts and can be rotated within a range of about 180 degrees by being supported by an insertion shaft support mechanism comprising a support groove that is inserted in a lowered state. It consists of things that are movably attached.

  The support groove may be formed in any one of a substantially I shape, a substantially inverted L shape, a substantially square shape, or a reverse letter shape having a tip opened to the outer edge of the support column.

  In addition, at least one of the four side panels may be configured to be foldable outwardly by a lower panel body and an upper panel body that are rotatably connected.

Since the present invention is configured as described in detail above, the following effects can be obtained.
(1) Since the four side panels can be folded inward, they can be stacked in a folded state and can be expanded outward, so one or more panels are opened. In this state, it is possible to perform the operation of storing the stored items such as agricultural products, so that the storing operation can be easily and efficiently performed, and the burden on the body can be reduced.
(2) Since the four side panels can be separated from the bottom panel, disassembly and cleaning can be easily performed, and a damaged bottom panel and some side panels can be easily replaced.
(3) Since the structure can be simplified as compared with the prior art, the manufacturing cost can be reduced.
(4) Since the support groove is formed in any one of a substantially I shape, a substantially inverted L shape, a substantially square shape, and a reverse letter shape, the upper end of which is open to the outer edge of the support column. Can be easily attached and detached, and the side panel can be reliably supported without being detached from the support column by an opening / closing operation, vibration during conveyance, or the like.
(5) Since at least one side panel can be folded in two from the middle in the height direction to the outside, the operator can squat down or sit down by putting the side panel in a folded state at the beginning of work. Since the stored items can be stored in the same posture, the burden of body movement can be greatly reduced and the work efficiency can be improved.

The outer leg 3A and the lateral frame 2C are fixed to each other by welding means in a state of facing rearward. The front struts 4 and 4 and the rear struts 5 and 5 are configured so that containers can be stacked horizontally by setting the upper ends to the same height.

  Reference numeral 11 denotes a front side panel pivotally supported between a pair of front struts 4 and 4 via an insertion shaft support mechanism 12 which will be described later. The front side panel 11 is composed of upper and lower cross members 11A and 11B and a pair of left and right side members. It is formed in a horizontally long rectangular frame from the vertical members 11C and 11C, and has a configuration in which three inner vertical members 11D, 11D and 11D are separated and connected between the upper and lower horizontal members 11A and 11B.
