Description

Technical Field

[0001] The invention relates to the technical field of design and manufacturing of logistics transport boxes, and more specifically to a self-discharging foldable turnover wooden tonnage box. Background Art

[0002] In the prior art, both IBC plastic barrels and metal boxes are equipped with discharge valves, but their respective disadvantages are as follows:

[0003] IBC plastic barrels are integrally injection molded and their discharge valves are external. The empty barrels cannot be folded during transportation, which results in high transportation costs, and the discharge valves are often damaged during transportation. The installation process of ton bags in IBC plastic barrels is very complicated and requires six steps (removing the discharge valve - placing the ton bag in the plastic barrel - blindly finding the pull ring in an invisible state - pulling the pull ring so that the ton bag outlet is covered on the valve interface and then installing the discharge valve - inflating the ton bag into the discharge valve through an air pump - fixing the inlet of the inflated ton bag on the upper mouth of the IBC plastic barrel) to complete the installation.

[0004] Although metal ton boxes can be folded, the panels are non-detachably connected and cannot be completely disassembled, resulting in a large volume after folding. In addition, due to their own weight, there is also the problem of high transportation costs.

[0005] The existing wooden box structure includes an upper top plate, a lower bottom plate and four side plates. During the loading and unloading process, the material is loaded and unloaded by connecting the feeding pump from the loading port on the top of the ton bag. This operation has problems such as excess material that cannot be unloaded completely and waste of labor and electricity resources. Summary of the invention

[0006] The purpose of the present invention is to simplify the installation process of ton bags, reduce transportation costs, and reduce material transfer losses as well as labor and electricity costs.

[0007] In order to achieve the above-mentioned purpose, the present invention provides a self-discharging foldable turnover wooden tonnage box, which is composed of a lower bottom plate, four side plates detachably mounted on the lower bottom plate, and an upper top plate detachably mounted on the four side plates; cross beams are installed at intervals at the bottom of the lower bottom plate, and forklift pinions can be accommodated between two adjacent cross beams, and a liquid discharge port is opened at the lower part of any side plate of the wooden tonnage box, and a self-discharging device is arranged in the liquid discharge port. The self-discharging device includes a discharge valve cover with a side opening abutting against the inner edge of the liquid discharge port, and a discharge valve arranged in the discharge valve cover; the lower part of the discharge valve cover is detachably fixed to the lower bottom plate; a circular fixing port is opened on the other side of the discharge valve cover relative to the side opening for the valve interface of the ton bag in the wooden tonnage box to extend into.

[0008] The inlet of the discharge valve is screwed to the valve interface of the ton bag, and the lower part of the discharge valve is detachably fixed on the lower bottom plate.

[0009] Because the discharge valve cover needs to bear the multi-directional pressure applied by the fully loaded ton bags, in order to stabilize the discharge valve cover and prevent it from shifting under pressure, it is preferred that the discharge valve cover and the discharge valve are connected to the lower base plate in a detachable fixed connection manner through a pin socket; and the pin at the bottom of the discharge valve cover and the pin at the bottom of the discharge valve pass through the ends of the lower base plate and are provided with through holes or threads for locking.

[0010] Because the discharge valve cover needs to bear the multi-directional pressure applied by the fully loaded ton bags, in order to ensure that the discharge valve cover can withstand greater pressure and not be crushed, it is preferred that the discharge valve cover is a cover body with a smooth and edge-free exterior and an operating chamber inside, and the outside of the discharge valve cover is provided with a plurality of reinforcing ribs extending laterally from the middle of the pressure-bearing surface compressed by the ton bags to the bottom ends on both sides.

[0011] The contact surface between the discharge valve cover and the liquid discharge port is small, which is prone to stress concentration and has a negative impact on the firmness of the box body and the discharge valve cover. Preferably, the side opening of the discharge valve cover and the abutment position of the liquid discharge port are widened.

[0012] In order to protect the drain port on the wooden box from damage caused by accidental insertion during transportation by a forklift, it is preferred that when the drain port is arranged at the lower part of the side panel on the working side of the forklift, its spatial position is within the interval between two groups of adjacent beams.

[0013] The valve interface of the ton bag should be kept stable and not shifted during transportation and loading. Preferably, matching anti-rotation fixing grooves are provided around the circular fixing opening according to the peripheral structure of the valve interface of the ton bag.

[0014] In order to facilitate unloading, preferably, the outlet of the discharge valve is screwed with an external discharge pipe or a quick connector.

[0015] The wooden box in the present invention can be completely disassembled, and occupies less space when transported empty. Compared with IBC plastic barrels and metal barrels, transport vehicles can transport more wooden boxes at the same volume, saving freight to the greatest extent. Compared with existing IBC plastic barrels, the installation steps of ton bags are greatly simplified, reducing material transfer losses and labor and electricity costs.

[0026] The structure of the present invention is as follows:

[0027] like Figure 1 As shown, a self-discharging foldable turnover wooden ton box is composed of a lower base plate 1, four side plates 2 detachably mounted on the lower base plate 1, and an upper top plate 3 detachably mounted on the four side plates 2; cross beams 10 are installed at intervals at the bottom of the lower base plate 1, and forklift tines can be accommodated between two adjacent cross beams 10, and a liquid discharge port 5 is opened at the lower part of any side plate 2 of the wooden ton box, and a self-discharging device is provided in the liquid discharge port 5.

[0028] like Figure 2As shown, the self-discharging device includes a discharge valve cover 8 whose side opening is abutted against the inner edge of the discharge port 5, and a discharge valve 6 arranged in the discharge valve cover 8; the side opening of the discharge valve cover 8 is widened at the abutment position with the discharge port 5. The inlet of the discharge valve 6 is screwed with the valve interface of the ton bag 4, and the lower part of the discharge valve 6 is detachably fixed on the lower bottom plate 1. The discharge valve cover 8 and the discharge valve 6 are connected to the lower bottom plate 1 in a detachable fixed connection mode of a pin plug hole; and the first pin 8-4 at the lower part of the discharge valve cover 8 and the second pin 9 at the lower part of the discharge valve 6 pass through the lower bottom plate 1. The ends are provided with through holes or threads for locking. Among them, when the lower parts of the first pin 8-4 and the second pin 9 are through holes, they can be fixed by a tightening lock strip or other straps. When the lower parts of the first pin 8-4 and the second pin 9 are threads, they can be locked and fixed by nuts respectively. When the discharge port 5 is arranged at the lower part of the side plate 2 on the working side of the forklift, the spatial position of the discharge port 5 is within the interval between two adjacent beams 10. The outlet of the discharge valve 6 is screwed with an external discharge pipe 7 or a quick connector. The discharge valve 6 is preferably a ball valve.

[0029] like Figures 3 to 6 As shown, the discharge valve cover 8 is a cover body with a smooth outer surface and no edges and corners, and an operating chamber inside, and the lower part of the discharge valve cover 8 is detachably fixed on the lower bottom plate 1; the discharge valve cover 8 is provided with a circular fixing opening 8-1 on the other side of the discharge valve cover 8 relative to the side opening for the valve interface of the ton bag 4 in the wooden ton box to extend into and place it to rotate; specifically, the circular fixing opening 8-1 is surrounded by matching anti-rotation fixing grooves 8-2 according to the peripheral structure of the ton bag valve interface. The discharge valve cover 8 is provided with a plurality of reinforcing ribs 8-3 extending horizontally from the middle of the pressure-bearing surface pressed by the ton bag 4 to the bottom ends of both sides.

[0030] The installation method of the present invention is as follows: Figures 7-8 As shown, after being transported to the unloading location, it is assembled. First, the ton bag 4 is placed on the lower base plate 1, and then the valve interface of the ton bag 4 is inserted into the anti-rotation fixing groove 8-2 behind the discharge valve cover 8 and fixed; after the inlet of the discharge valve 6 is screwed to the valve interface of the ton bag 4, the first pin 8-4 and the second pin 9 at the bottom of the discharge valve cover 8 are inserted into the lower base plate 1 at the same time.

[0031] The first latch pin 8 - 4 and the second latch pin 9 are connected and fixed together by a tension lock strip or are respectively screwed and fixed on the lower base plate 1 by two bolts.

[0032] Finally, the four side panels 2 are sequentially installed around the lower base plate 1.

[0033] The loading step of the present invention is as follows: the inlet of the ton bag is hung on a bridge clamp widely used in the prior art to be fixed, and then filling is performed.

[0037] 320 folding empty wooden boxes are loaded on a 17.5-meter truck, with a freight cost of 29,000 yuan / truck, minus the freight cost of 90 yuan / box for 320 folding empty wooden boxes.

[0038] The wooden tonnage box, the discharge valve and the discharge valve cover of the present invention can be recycled to save production costs. When recycling, the discharge valve and the discharge valve cover are quantitatively placed in the empty wooden tonnage box and folded with the box board for recycling.
