JPH064694Y2 - A container door mounting device for agricultural products - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is an improvement of the door mounting portion of a container for agricultural products.

(Prior Art) A container for agricultural products in which a door is folded up and down so as to be suitable for feeding a harvested product has already been proposed by the applicant as a device of Japanese Utility Model Publication No. 49-5570.

(Problems to be solved by the device) However, in the container like the previous proposal, the purpose of preventing the damage due to impact by folding the door and lowering the entrance to reduce the drop at the time of dropping the sent object can be achieved. Since the upper and lower doors are opened as a unit when removing contained items, vulnerable contained items such as potatoes are at high places (about 1.3% for ordinary containers).
It is packed up to the height of m. ) There was a problem that many scratches could be caused by the impact when falling.

(Means for Solving the Problems) The present invention is intended to solve the above problems by making it possible to open the lower door of the container independently. FIG. 1 is a front view of a container door for agricultural products having a mounting device of the present invention, FIG. 2 is a sectional view of a door shaft fitting portion of the device, and FIG. 3 is an inner side view of a bearing portion.

In the drawings, 1 is a front outer frame of a container, and a door 2 is arranged inside the frame.

The door 2 is divided in the middle of the peripheral frame 3 by a horizontal member 4, and an upper door 5 and a lower door 6 are hinged above and below the member by hinges 7 and 8, respectively.

Pins 9 and 10 are attached near the upper end and the middle part on the outside of each of the left and right peripheral frames 3, and these are provided near the upper end of the inner surface of the outer frame 1 and in the middle part, respectively. 11 and the lower bearing holes 12 opened on the outer side of the upper part, and are attached to and detached from the outer frame 1 and the underframe 21 (FIG. 7) near the left and right upper ends of the upper door 5 and the lower left and right of the lower door 6, respectively. The tools 13 and 14 are attached.

(Operation) The door 2 of the container having the door mounting device of the present invention has a strong frame structure composed of the peripheral frame 3 and the cross member 4, and the pins 9 and 10 and the outer frame 1 attached to the left, right, upper and lower four positions of the frame. Accurately held in the outer frame 1 by the specially-formed bearing holes 11 and 12, the upper door 5 is opened not only when the harvest product is sent, but also when the product is taken out, the lower door 6 is opened independently to accommodate the low head. You can take things out,
Even when a considerable amount of force is applied intermittently to the entire surface of the door when it is taken out, it does not oscillate due to the bearings at the above-mentioned four locations, and after taking out the contents, it can be easily removed by slightly lifting the door and pulling it forward. it can.

(Example) FIG. 4 is a schematic front view of a container embodying the present invention, FIG.
The figure is a schematic side view showing the rear structure by cutting off a part of the outer frame, FIG. 6 is a side view of the upper door hanging / detaching tool, and FIG. 7 is a front view of the lower door hanging / detaching tool.

In the drawing, reference numeral 21 designates an underframe attached to the lower portion of the outer frame 1, and the upper surface thereof is constituted by a large number of tension plates 22. As shown in FIG. 6, the upper door engaging / disengaging device 13 is configured so that a part of the handle 25 axially attached to the left and right of the peripheral frame 3 of the door can be engaged and disengaged with respect to the receiving ring 24 attached to the outer frame 1. Has become.

As shown in FIG. 7, the lower door hooking / dismounting tool 14 is configured such that a part of the handle 26 axially attached to the lower side of the peripheral frame 3 of the door is hooked / unhooked on a part of the pallet base. .

(Effect) In the container door mounting device for agricultural products of the present invention, the upper door 5 and the lower door 6 are hinged so that they can be opened and closed in a strong frame composed of the peripheral frame 3 and the cross member 4, and the peripheral frame is further extended. Since the frame 3 is accurately held in the outer frame 1 by the four special bearings on the left, right, top and bottom, the crops can be sent in and taken out without damage, not only when the crops are sent in but also when they are taken out due to their low heads. In addition, it is possible to easily attach and detach the entire door 2.
