[0046] Specifically, through the designed flexible supporting unit 8, when a number of materials are placed in the storage box 3, the materials at the bottom layer can be buffered by the support of the flexible supporting film 801, so as to prevent the fruits and vegetables at the bottom layer, which have easily damaged skins, from coming into contact with the hard bottom wall and being damaged.

[0048] See also Figure 3-Figure 4 A first electric push rod 504 is connected to one side of the track frame 501. The first electric push rod 504 is fixed in a receiving groove opened on one side of the tank body inside the storage box 3. The width of the tank body of the storage box 3 is greater than the width of the track frame 501. The partition position is adjusted by moving the track frame 501. The shielding pad 11 is retractably connected between the track frame 501 and the tank wall of the tank body of the storage box 3. One side of the shielding pad 11 is fixedly connected to the track frame 501, and the other side of the shielding pad 11 is fixedly connected to the tank wall of the tank body of the storage box 3. The shielding pad 11 is a pleated telescopic structure, which can be telescopically adjusted between the track frame 501 and the tank wall of the tank body of the storage box 3.

[0049] Specifically: through the designed first electric push rod 504, the track frame 501 can be controlled to slide in the trough body through the extension and contraction of the first electric push rod 504. When the track frame 501 moves, the position of the traction roller 505 at the bottom of the flexible supporting membrane 801 can be adjusted, so that the partition chamber can be adjusted by adjusting the position of the traction roller 505, which is convenient for adjusting the amount of material unloading to match the single partial unloading requirements.

[0050] See also Figure 3 , Figure 4 , Figure 8 and Fig. 9 Both ends of the flexible supporting film 801 are wound and connected with a winding roller 802, and the bottom of the winding roller 802 is rotatably connected with a supporting frame 803, and both ends of the bottom of the supporting frame 803 are provided with a telescopic rod 804, one end of the telescopic rod 804 is fixedly connected to the supporting frame 803, and the other end of the telescopic rod 804 is fixed in a receiving groove opened at the top of the bottom frame 9, and a second spring 805 is sleeved on the outer wall of the telescopic rod 804, and the two ends of the second spring 805 are respectively connected with the bottom of the supporting frame 803 and the telescopic rod 804, wherein the telescopic rod 804 includes a fixed tube and a telescopic rod inserted in the fixed tube, the upper end of the second spring 805 is fixed on the supporting frame 803, and the lower end of the second spring 805 is fixed to the upper end surface of the fixed tube.

[0051] The lifting mechanism 6 is slidably connected to both sides of the track frame 501. The lifting mechanism 6 includes lifting rods 601 located on both sides of the traction roller 505. The distance between the lifting rods 601 and the traction roller 505 is adjustable. One end of the lifting rod 601 is connected to a fixed block 602. One side of the fixed block 602 is fixedly connected to one end of the second electric push rod 603. The other end of the second electric push rod 603 is fixedly connected to a slider 604. The slider 604 is slidably connected to a slide groove opened on the side of the track frame 501. The slider 604 has a slide hole that passes through from top to bottom, and a guide rod 605 is slidably connected in the slide hole. The two ends of the guide rod 605 are respectively fixedly connected to the upper and lower ends of the slide groove. The outer cover of the guide rod 605 is provided with a first spring 606. The two ends of the first spring 606 are respectively connected to the slider 604 and the upper end of the slide groove.

[0052] Specifically: through the designed lifting mechanism 6, when the traction roller 505 moves upward to the top of the lifting rod 601, the flexible supporting film 801 is pulled and can be in contact with the lifting rods 601 on both sides. At this time, the flexible supporting film 801 bypasses the bottom of the lifting rod 601 on one side, then bypasses the top of the traction roller 505, and then bypasses the bottom of the lifting rod 601 on the other side, so that the flexible supporting film 801 is in a "J" shape under the joint support and limiting action of the traction roller 505 and the two lifting rods 601, so as to improve the full placement effect of the material, and the lifting rod 601 can adjust the corresponding position of the lifting rod 601 from the track frame 501 through the working extension of the second electric push rod 603, which is conducive to adjusting the shape of the flexible supporting film 801 by adjusting the position of the lifting rod 601, so as to move the material in the accommodating cavity toward the discharge port.

[0053] Through the designed winding roller 802, when the flexible supporting film 801 moves upward, the film body is released by the winding rollers 802 on both sides to avoid damage to the flexible supporting film 801 due to excessive traction, and when the flexible supporting film 801 is pulled, the bottom of the winding roller 802 can pull the second spring 805 through the expansion of the telescopic rod 804, and the second spring 805 can absorb the traction tension by its own elastic force, which is beneficial to improve the impact resistance. In this embodiment, an automatic winding device is provided at the end of the winding roller 802. When the tension of the flexible supporting film 801 decreases, the automatic winding device can drive the winding roller 802 to rotate to rewind the flexible supporting film 801. The structure and principle of the automatic winding device belong to the prior art and will not be described in detail here.

[0054] Gate mechanisms 7 are provided on both sides of the storage box 3, and the gate mechanisms 7 include a closed gate 701 for blocking the discharge port, and an inner cavity for accommodating the closed gate 701 is provided at the top of the discharge port, and third electric push rods 702 are connected to both sides of the top of the closed gate 701. A groove body for accommodating the third electric push rod 702 is provided at the top of the inner cavity of the discharge port, and the discharge port can be set to a rectangular or circular outlet as needed to realize partial discharge of materials.

[0055] Specifically: through the designed gate mechanism 7, the third electric push rod 702 can be shortened to pull the closed gate 701 to move upward and extend into the inner cavity. When the closed gate 701 is opened upward, the partitioned materials in the storage box 3 can be moved out from the opened discharge port, which is beneficial to the unloading and discharge of materials and improves the unloading effect of some materials during storage.

[0056] Working principle: During use, after a number of materials are placed in the storage box 3, the materials at the bottom layer are reduced in strength of hard contact through the setting of the flexible supporting film 801 and the buffer strip 10, so as to avoid damage caused by contact between the materials at the bottom layer and the hard bottom wall. When the output shaft of the driving motor 503 at the top of the track frame 501 rotates, the adjusting screw 506 is driven to rotate, and the rotation of the adjusting screw 506 drives the external screw seat 507 to move. The movement of the screw seat 507 drives the traction roller 505 to move. The movement of the traction roller 505 pulls the flexible supporting film 801 at the abutment position upward, and accommodating cavities are formed on both sides of the storage box 3 through the upwardly raised flexible supporting film 801. The materials are stored in partitions through the accommodating cavities, and the materials in some accommodating cavities are unloaded.

[0057] The first electric push rod 504 is used to control the track frame 501 to slide in the trough body. When the track frame 501 moves, the position of the traction roller 505 at the bottom of the flexible supporting film 801 is adjusted, which is conducive to adjusting the partition chamber by adjusting the traction position of the traction roller 505, and conveniently adjusting the amount of discharged material.

[0058] When the flexible supporting film 801 is pulled, it abuts against the lifting rods 601 on both sides. When the pulling roller 505 moves upward to the top of the lifting rod 601, the flexible supporting film 801 is pulled and can abut against the lifting rods 601 on both sides, so that the flexible supporting film 801 is combined into a "J" shape under the support of the pulling roller 505 and the two lifting rods 601, and the lifting rod 601 is extended by the second electric push rod 603 to adjust the corresponding position of the lifting rod 601 from the track frame 501. By adjusting the position of the lifting rod 601, the inclination angle of the side wall of the flexible supporting film 801 is adjusted.

[0059] When the flexible supporting film 801 moves upward, the film body is released by the winding rollers 802 on both sides to avoid damage to the flexible supporting film 801 caused by excessive traction. When the flexible supporting film 801 is pulled, the bottom of the winding roller 802 pulls the second spring 805 through the expansion of the telescopic rod 804, and the second spring 805 absorbs the traction force with its own elastic force.

[0060] The third electric push rod 702 is shortened and pulled to move the closing gate plate 701 upward, and when the closing gate plate 701 is opened upward, the partitioned materials in the storage box 3 are moved out from the opened discharge port.
