[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] refer to Figures 1-5 As shown, a material transfer hopper with an automatically opening and closing bottom plate includes a hopper 1, a bottom plate 4, and a discharge rack 8. The discharge rack 8 is placed at the bottom of the hopper 1. The hopper 1 is welded from steel plates to improve the overall strength of the hopper 1. The top of the hopper 1 is open to facilitate material loading. Pin sleeves 2 are welded to the lower front and rear sides of the hopper 1. Two bottom plates 4 are provided and placed below the hopper 1. Pin shafts 5 are welded to the ends of the bottom plates 4. The pin shafts 5 rotate inside the pin sleeves 2, and the two bottom plates 4 seal the bottom of the hopper 1. The bottom plates 4 rotate around the pin sleeves 2 under the action of gravity to open, thereby realizing the opening and closing of the bottom hopper door. The ends of the two bottom plates 4 that are close to each other are welded downwards. The reset column 10 is used to reset the bottom plate 4 when it is closed, so that the bottom of the hopper 1 is sealed. The bottom plate 4 is provided with locking pins 15 on both sides of the end near the reset column 10, so as to fix the bottom 4 and keep it sealed by fixing the locking pins 15. Cylindrical pins 13 are symmetrically welded on both sides of the hopper 1. Control plates 6 are rotatably mounted on the surface of the cylindrical pins 13. The control plates 6 are L-shaped. The lower end of the control plates 6 is symmetrically provided with limiting arc grooves 61. The end of the limiting arc grooves 61 is provided with chamfers so that when the bottom plate 4 is closed, the locking pins 15 can enter the limiting arc grooves 61 through the chamfers. The locking pins 15 are cylindrical. Two locking pins 15 on the same side are adapted to the inner sides of two limiting arc grooves 61. A pusher 17 is provided downward at the other end of the control plate 6. When the hopper 1 is placed on the unloading rack 8, the control plate 6 can be rotated by pushing the pusher 17 upward, thereby releasing the limitation on the locking pins 15. A reset spring 11 is connected to the surface of the control plate 6. The other end of the reset spring 11 is connected to the side surface of the hopper 1. The reset spring 11 resets the control plate 6.

[0023] refer to Figure 2 As shown, the unloading rack 8 includes four columns at the bottom and a support plate 18 at the top. A square hole is opened in the center of the surface of the support plate 18 for material discharge. Unloading columns 9 are symmetrically welded on the upper surface of the support plate 18, which can be placed on the push column 17 when the hopper 1 is lowered.

[0024] Among them, the two unloading columns 9 are respectively placed at the two corners of the central square hole of the support plate 18. The position of the unloading column 9 corresponds to the bottom of the push column 17. The unloading column 9 is used to push the push column 17 upward.

[0025] refer to Figure 1 and Figure 2As shown, positioning plates 19 are welded to the left, right and rear sides of the upper surface of the support plate 18. The positioning plates 19 are used to position the hopper 1 to ensure that the hopper 1 is accurately placed into the fixed position and to prevent displacement.

[0026] refer to Figure 3 and Figure 6 As shown, a fork support plate 3 is welded to the upper part of the hopper 1. The fork support plate 3 is used to provide a point of leverage for the forklift.

[0027] refer to Figure 1 and Figure 6 As shown, symmetrical transfer bucket support columns 12 are welded on both sides of the hopper 1. The transfer bucket support columns 12 are used to support the hopper 1, so that the bottom of the hopper 1 is hollowed out. The bottom of the transfer bucket support column 12 is flush with the bottom of the reset column 10 in the closed state, so that when the hopper 1 is placed on the ground, the bottom plate 4 can be closed by the reset column 10.

[0028] refer to Figure 3 As shown, a V-shaped plate 14 is welded to the upper surface of the fork support plate 3. A bottom plate pull rope 7 is connected to the surface of the V-shaped plate 14. Pull rope fixing plates 16 are symmetrically welded to both sides of the bottom plate 4. The end of the bottom plate pull rope 7 away from the fork support plate 3 is connected to the pull rope fixing plate 16. The bottom plate pull rope 7 is used to control the maximum opening angle of the bottom plate 4. The maximum opening angle of the bottom plate 4 shall not exceed 90 degrees to ensure that the bottom tilts inward after opening so that it can automatically close when squeezed by the ground.

[0029] The working principle of this utility model is as follows: First, the material is placed inside the hopper 1. Then, the hopper 1 is lifted and transported to the top of the unloading rack 8 by the cooperation of the forklift and the fork support plate 3. Through the positioning of the left, right and rear positioning plates 19, the hopper 1 is positioned exactly at the center of the support plate 18. The hopper 1 is slowly lowered along the inner wall of the positioning plates 19 until it is in complete contact with the support plate 18. During the lowering process, the unloading column 9 pushes the push column 17 upward, causing the control plate 6 to rotate, which in turn causes the limiting arc to move upward. When the groove 61 rotates to one side, the return spring 11 is pulled and stored. At this time, the control plate 6 releases the restriction on the locking pin 15. Due to its own weight, the bottom plate 4 can rotate around the pin sleeve 2, so that the bottom of the hopper 1 opens. When it opens, the bottom plate pull rope 7 pulls the bottom plate 4 to limit its maximum opening. The bottom plate 4 on one side cannot rotate downwards and open more than 90 degrees. At this time, the material inside the hopper 1 will fall into the material bag or other container through the bottom opening and the square hole on the surface of the support plate 18 to realize automatic feeding.

[0030] After a single unloading operation, the hopper 1 is lifted using a forklift. When lifted, the pusher column 17 is no longer squeezed by the unloading column 9. At this time, the storage force of the return spring 11 can be used to make the control plate 6 return to its original position. Then, the hopper 1 is placed on the ground. Since the bottom plate 4 is open downwards and the opening angle is less than 90 degrees, the top of the bottom plate 4 is tilted inwards. When the hopper 1 is placed on the ground, the return column 10 at the bottom of the bottom plate 4 will be squeezed by the ground and drive the bottom plate 4 to gradually close inwards until the hopper 1 is completely flat and the bottom of the return column 10 is also completely in contact with the ground. At this time, the bottom plate 4 is in a completely closed state. Both sides of the limiting arc groove 61 are provided with chamfers. Therefore, during the lowering process, the locking pin 15 can be re-entered into the limiting arc groove 61 through the chamfers, thereby achieving limited locking and fixing of the bottom plate 4 for the next transfer operation.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
