[0036] Example 1

[0037] This embodiment provides another type of waste storage and transfer box for storing and transferring scrap steel and iron filings generated during the processing of marine diesel engines and large steel structure components.

[0038] like Figures 1-4 As shown, the waste storage and transfer box includes a box body with a cubic structure, which is welded from Q235B steel plate. Multiple profiles are provided on the outer side of the steel plate to enhance the structural strength of the box body. It can bear a maximum weight of 8T of waste. The box body has four side walls, namely front box wall 1, rear box wall 2, left box wall 3 and right box wall 4. The four side walls form a cubic structure with open top and bottom.

[0039] A base 5 is provided at the bottom opening of the box. The front edge of the base 5 is rotatably connected to the bottom of the front box wall 1 of the box via a hinge 6. The base 5 can rotate around the axis of rotation of the hinge 6 to switch between sealing or opening the bottom opening of the box.

[0040] A locking mechanism 7 is provided between the rear edge of the base 5 and the rear wall of the box body. The locking mechanism 7 is used to switch between the locked and unlocked states of the base and the rear box body.

[0041] Furthermore, support legs 8 are provided at the four corners of the bottom surface of the base 5, so that the entire waste storage and transfer box can be placed on the ground by the support legs, which are used to support the entire transfer box.

[0042] In this embodiment, two locking mechanisms 7 are provided at the bottom of the rear wall of the box, and the two locking mechanisms 7 are symmetrically arranged with respect to the vertical center line of the rear wall.

[0043] The two locking mechanisms 7 are completely identical in structure, and one of the locking mechanisms 7 is taken as an example for description.

[0044] As shown in Figure 5 , the locking mechanism comprises a rotating shaft 7-1 coaxially penetrating through a positioning sleeve 7-2 and rotationally connected with the positioning sleeve 7-2. In the embodiment, two positioning sleeves 7-2 are provided, and both of the two positioning sleeves are fixedly connected with the rear cabinet wall 2 of the cabinet.

[0045] The top end of the rotating shaft 7-1 is connected with a handle 7-4 perpendicular to the rotating shaft 7-1 through a pin shaft 7-3. The top surface of the upper positioning sleeve 7-2 is provided with a limiting sleeve 7-5, and the handle 7-4 is in contact with the limiting sleeve 7-5. The handle 7-4 can prevent the rotating shaft 7-1 from being separated from the positioning sleeve 7-2. The bottom end of the rotating shaft 7-1 is provided with a locking block 7-6 perpendicular to the rotating shaft 7-1. The thickness of the locking block 7-6 is less than the height of the supporting leg 8, so that the locking block 7-6 can be rotated to below the base 5 and in contact with the lower surface of the base 5 under the action of the rotating shaft 7-1, thereby preventing the base 5 from rotating, and achieving the locking and fixing of the base 5 and the rear cabinet wall 2.

[0046] When the rotating shaft is rotated through the handle 7-4, the locking block 7-6 is separated from the bottom surface of the base 5. At this time, the rotation of the base 5 is not limited, and the base 5 can freely rotate through the hinge 6.

[0047] The left cabinet wall 3 and the right cabinet wall 4 of the cabinet are provided with a buffer mechanism 9 at the bottom of the outer side surface of the front end. The buffer mechanisms 9 on both sides are completely identical in structure and are symmetrically arranged with respect to the center of the cabinet. One of the buffer mechanisms 9 on both sides is taken as an example for description.

[0048] As shown in Figures 6-9 , the buffer mechanism 9 comprises a first friction component and a second friction component used in cooperation. The first friction component and the second friction component are oppositely arranged, and a buffer plate 9-1 penetrates between the first friction component and the second friction component. The bottom end of the buffer plate 9-1 is fixed to the side surface of the base 5. The first friction component and the second friction component can exert a friction force on the buffer plate 9-1, so that the base 5 can be slowly opened, thereby avoiding the phenomenon that the spilled waste splashes when the base 5 is rapidly opened due to the separation of the locking block 7-6 from the base 5.

[0049] The buffer plate 9-1 is in the shape of a circular arc, and the center of the inner arc surface of the buffer plate is located on the rotation axis of the base 5, i.e. the axis of the hinge 6. With this arrangement, the smoothness of the rotation of the base is not affected after the buffer plate 9-1 is clamped by the first friction component and the second friction component.

[0050] The first friction component is arranged at the rear side of the second friction component, comprising a mounting cylinder 9-2, the axis of the mounting cylinder 9-2 is perpendicular to the front box wall 1 and the rear box wall 2, a roller mounting frame 9-3 is telescopically connected in the mounting cylinder 9-2, the roller mounting frame 9-3 can move linearly along the axis of the mounting cylinder 9-2, the roller mounting frame 9-3 is extended to the outside of the mounting cylinder 9-2 through the first end of the mounting cylinder 9-2, and the second end of the mounting cylinder 9-2 is opposite to the first end.

[0051] The end of the roller mounting frame 9-3 extended to the outside of the mounting cylinder 9-2 is rotationally connected with a first roller 9-4, and the wheel surface of the first roller 9-4 is in contact with the outer arc surface of the buffer plate 9-1.

[0052] The roller mounting frame 9-3 is elastically connected with the mounting cylinder 9-2, specifically, a spring 9-8 is arranged in the mounting cylinder 9-2, one end of the spring 9-8 is connected with the end of the roller mounting frame 9-3, and the other end is in contact with an adjusting member arranged at the second end of the mounting cylinder 9-2.

[0053] Specifically, the spring is sleeved on the outer periphery of the guide rod, and the guide rod is fixed to the end of the roller mounting frame 9-3 extended into the mounting cylinder.

[0054] The end of the roller mounting frame 9-3 located in the mounting cylinder is provided with a larger-diameter limiting section, forming a stepped shaft structure, and the shaft shoulder formed can be in contact with the inner side surface of the end of the mounting cylinder, so as to limit the distance of the roller mounting frame 9-3 extended out of the mounting cylinder, and prevent the roller mounting frame 9-3 from being completely separated from the mounting cylinder 9-2.

[0055] The adjusting member adopts a knob 9-5 threadedly connected with the mounting cylinder, and the knob 9-5 can move linearly along the axis of the mounting cylinder 9-2 by rotating the knob 9-5, so as to adjust the initial elastic force of the spring, thereby meeting the buffering requirements when waste of different weights is poured, and improving the applicability of the waste storage and transfer box.

[0056] The second friction component adopts a second roller 9-6, the second roller 9-6 is rotationally connected with the box wall of the box body through an axle, the axle is fixed on a base 9-9, the base 9-9 is fixed with the box wall of the box body, one side of the second roller 9-6 is the base 9-9, and the other side is provided with a gasket 9-10, the outer side of the gasket 9-10 is provided with a hexagonal head bolt 9-7, the bolt 9-7 is threadedly connected with the axle. The wheel surface of the second roller 9-6 is in contact with the inner arc surface of the buffer plate 9-1, and in order to enable the buffer plate 9-1 to be in contact with the first roller 9-4 and the second roller 9-6 at all times, an annular groove is formed in the wheel surface of the second roller 9-6, and the buffer plate 9-1 is clamped into the annular groove.

[0057] The first roller 9-4 and the second roller 9-6 are clamped on both sides of the buffer plate 9-1, and the wheel surface is in contact with the buffer plate 9-1. The circular-arc-shaped buffer plate 9-1 can ensure sufficient friction and avoid the jamming phenomenon when the base 5 rotates.

[0058] In this embodiment, the width of the buffer plate 9-1 gradually increases from the bottom end to the top end. When the base 5 rotates to gradually increase the opening degree, the spring force gradually increases under the action of the buffer plate 9-1, thereby increasing the clamping force of the buffer plate 9-1 and further increasing the friction force of the buffer plate 9-1. This further plays a buffering role, so that the base 5 rotates slower as the opening degree increases, thereby improving the effect of preventing waste from splashing.

[0059] The top end of the buffer plate is provided with a limiting boss, and the first roller 9-4 and the second roller 9-6 can be in contact with the limiting boss to limit the rotation angle of the base 5.

[0060] The bottom of the front wall 1 of the box body is provided with a plurality of forklift holes 10, and the positions and shapes of the forklift holes 10 are matched with the forklift 11. The steel fork of the forklift 11 can be inserted into the forklift hole 10, thereby realizing the transfer of the waste storage and transfer box.

[0061] The working method of the waste storage and transfer box of this embodiment is as follows:

[0062] As shown in Figure 10 The waste steel scraps and iron scraps generated during the machining of marine diesel engines or large steel structure parts are placed into the box body from the top opening of the box body, and the waste storage and transfer box stores the waste. When the box body is full, the forklift 11 moves to the designated position, and then the forklift 11 is operated to insert the steel fork into the forklift hole 10 of the box body.

[0063] The waste storage and transfer box filled with waste is transferred to the waste transfer station by the forklift 11, and the steel fork of the forklift 11 is lifted to a designated height.

[0064] The handle 7-4 is rotated to make the locking block 7-6 disengage from the bottom surface of the base 5. The waste in the box body drives the base 5 to rotate around the axis of the hinge 6 under the action of gravity.

[0065] Due to the spring force, the first roller 9-4 and the second roller 9-6 always apply pressure to the buffer plate 9-1, thereby generating friction. Therefore, the base 5 is slowly opened, and the waste is slowly poured out, rather than being opened instantaneously, thereby avoiding the waste splashing phenomenon, ensuring safety, and improving work efficiency without the need to clean the waste.

[0066] After the waste dumping is completed, the forklift lowers the waste storage transport box until the rear end of the base 5 contacts the ground, and the forklift continues to lower the waste storage transport box, the base 5 and the buffer mechanism 9 continue to work, the base 5 slowly rotates and closes, and the bottom opening of the box body is blocked. After the base rotation is completed, the rotating handle 7-4 is rotated to make the locking block 7-6 contact the bottom surface of the base 5, and the locking of the base 5 and the rear box wall 2 is completed.

[0067] The forklift 11 drives the waste storage transport box to move to the original waste storage place, then withdraws the steel fork, and the forklift 11 drives away.

[0068] The waste storage transport box of the embodiment gradually enlarges and widens the buffering force on the basis of the first friction component compression force; when the weight in the box body is too large and the buffering device pre-tightening force is not enough, the buffering force can be supplemented by the gradually enlarging and widening feature of the buffering plate, the bottom of the box body is prevented from being opened instantaneously, and the improvement does not need to increase hydraulic or electric components, only mechanical components that can be manually controlled are increased, no components that need to be automatically controlled are increased, and the improvement cost is low.

[0069] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
