Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0022] like Figure 1-3 As shown, this utility model relates to a breathable container bag, including a bag body 1, which has a rectangular structure with a width and height of 1800mm and a length of 9500mm. A platform 3 is located on the bottom surface of the bag body, made of a lightweight material such as foam. The length of the platform is half the length of the bag body. Horizontal sleeves 8 are symmetrically arranged on both sides of the platform. An inlet 12 and a cover sheet 2 are located in the middle of the top surface of the bag body. The cover sheet 2 is flexible and flip-up, with dimensions of 1800x400mm. A hook and loop fastener patch 10 is provided on the cover sheet 2. The back of the hook and loop fastener patch is a non-slip silicone layer, which is melted at high temperature in a sol-gel machine and evenly dripped onto the back of the hook and loop fastener patch to form a plate, which is sewn to the cover sheet 2. Hook and loop hook patches 14 are located at corresponding positions on the connecting strip of the top surface of the bag body and the cover sheet after rotation. The hooks have several hook structures of varying heights, which can increase the connection between the hooks and loop fastener patches. The contact area and friction are increased to improve the sealing effect; the flipping of the cover sheet can seal the feed port with Velcro; an adhesive strip 22 is set in the middle of the free end of the cover sheet; an exhaust port is set at the front end of the top of the bag body, and a flap strip 23 is set at the corner of the top surface of the bag body; a Y-shaped merging structure is set on the cover sheet and the top surface of the bag body, and three parallel discharge ports 7 are set below the end face of the bag body. Binding ropes 13 are set on both the feed port and the discharge port. The number of discharge ports 7 is set to three to increase the unloading efficiency; metal corner brackets 4 are set at the corner of the top surface of the bag body, and connecting ropes 6 are set on the metal corner brackets 4; a hanging ring 5 is set on the connecting rope. The hanging ring is made of stainless steel and has a diameter of 10cm; the bag body has a composite layer structure, which includes a breathable layer 15, a PP woven fabric layer 16, a cover layer 17 and a canvas layer 18 from the inside out. The PP woven fabric layer and the canvas layer have breathable holes. They are formed by hot pressing and weaving.

[0023] As a technical improvement, the metal corner frame 4 has three corner blocks 41 that are connected perpendicularly to each other. The metal corner blocks are provided with perforations 43 and then sewn to the bag body.

[0024] As a technical improvement, the breathable layer 15 is made of breathable fabric, which includes a base fabric layer. The base fabric is made of weft yarns and warp yarns interwoven together. The weft yarns and warp yarns are designed with two spacings: 0-0.1 mm and 0.3-1 mm. The weft yarns and warp yarns are designed with two spacings: 0-0.1 mm and 0.3-1 mm. The 0-0.1 mm spacing is used to ensure the basic structural strength of the breathable layer, and the 0.3-1 mm spacing is used to increase the breathability. A coating is applied to the fabric layer as a shaping structure.

[0025] As a technical improvement, a hanging ring 42 is provided on one of the corner blocks, one end of the connecting rope is connected to the hanging ring, and the other end is connected to the hanging ring 5.

[0026] As a technological improvement, the covering layer is woven from ceramic fiber filaments and fixed with double stitching. Its surface is also designed with small holes, the size of which is 0.5 to 1.2 mm.

[0027] As a technical improvement, the bag body is provided with bracing pieces 121 at the four corners.

[0028] Furthermore, the Y-shaped merging structure includes a Y-shaped retaining ridge 91 disposed on the bottom surface of the cover sheet and a Y-shaped retaining groove 9 disposed on the top surface of the bag body. The feed inlet is located between two relatively close support grooves of the Y-shaped retaining groove. Both the Y-shaped retaining ridge and the Y-shaped retaining groove are made of high-strength, wear-resistant plastic material to ensure that they are not easily damaged during long-term use. The surface of the Y-shaped retaining ridge is smoothed to reduce frictional resistance between it and the Y-shaped retaining groove, facilitating their insertion and separation. A sealing rubber strip is provided inside the Y-shaped retaining groove. When the Y-shaped retaining ridge is inserted into the Y-shaped retaining groove, the sealing rubber strip can tightly fit the surface of the Y-shaped retaining ridge, forming a good sealing effect and effectively preventing leakage of materials inside the bag and the entry of external dust. During installation, the Y-shaped retaining ridge is firmly attached to the bottom surface of the cover sheet with strong adhesive to ensure accurate positioning and a stable connection; the Y-shaped retaining groove is fixed to the top surface of the bag body by sewing, using high-strength nylon thread.

[0029] Furthermore, the cover sheet is provided with an external convex and concave surface 21 that matches the feed inlet. When the cover sheet covers the top surface of the bag, the external convex and concave surface is used to accommodate the feed inlet and play a protective role.

[0030] Furthermore, a shielding curtain 11 for covering the discharge port is provided at the front end of the bag body, and the rotation radius of the shielding curtain is greater than the distance from the bottom surface of the bag body at the point of rotation of the shielding curtain.

[0031] like Figure 4As shown, to facilitate securing the bag after unloading, at least two long binding ropes 19 are included, each equipped with a buckle 20. This design is an innovative one not found in existing technology. After unloading, the lifting ring is first connected to the hook on the top of the carriage to suspend the bag. Then, the bottom and top surfaces of the bag are folded together, and the binding ropes are wrapped around the bag, with the free ends of the ropes locked by the buckles, thus securing the entire container bag.

[0032] When in use, the hanging rings at the corners of the bag are hung on the inner wall of the truck. The inner wall has corresponding hooks. The purpose of the platform is to stabilize the bag, and the platform forms a recessed area with the bottom of the bag, allowing material above the platform to flow naturally towards the front of the bag during discharge. The cover curtain is used to cover the outlet after it is secured. Excess length can be pressed against the bottom of the bag. When the cover is placed on the top of the bag, the adhesive strips and overlapping strips on the cover work together to cover the exhaust port. The bottom of the bag is secured using a horizontal sleeve. During use, a steel pipe needs to be installed on the side of the vehicle's underside, passing through the horizontal sleeve. A separate long rope is designed to secure the entire bag after unloading, and a locking buckle is used to lock the free end of the rope.
