[0004] When the weighing in the above patent reaches the target value, the air pump cannot be timely closed and the feeding pipe cannot be sealed, and the residual materials in the suction hopper will fall into the weighing box, so that the actual weight of the materials in the weighing box is greater than the expected weight, and the material weight error is large. Summary of the Utility Model

[0010] Further, it further includes a tassel. A tassel is connected to the bottom of the sealing half-funnel.

[0011] Further, when the air pump is closed, the volume of the funnel formed by the two sealing half-funnels is greater than the volume of the possible remaining material in the suction hopper.

Detailed implementation

[0021] The following describes the present utility model in detail with reference to the accompanying drawings.

[0022] Embodiment: A suction machine device with a weighing function, as Figures 1 - 3 shown, includes a mounting frame 1, a suction hopper 2, a suction pipe 21, an air pump 3, an exhaust pipe 31, a guide pipe 4 and a blocking net 5. The mounting frame 1 is connected with the suction hopper 2. The air pump 3 is installed on the top of the suction hopper 2 through a flange. The suction hopper 2 is connected with a suction pipe 21 for sucking materials. The air pump 3 is connected with an exhaust pipe 31 for discharging gas. A blocking net 5 is arranged at the connection between the suction hopper 2 and the air pump 3 to prevent materials from entering the air pump 3. A guide pipe 4 for gathering materials is arranged at the bottom of the suction hopper 2. It also includes a weighing component and a separating component. A weighing component for accurately weighing materials is arranged at the bottom of the mounting frame 1. A separating component for blocking the falling of materials is arranged in the middle of the mounting frame 1. The separating component is located directly below the guide pipe 4.

[0023] As Figure 2 and Figure 3 shown, the weighing component includes a motor 6, a rotating frame 61, a weighing sensor 62 and a loading frame 63. The motor 6 is installed outside the mounting frame 1. The output shaft of the motor 6 passes through the mounting frame 1 and is connected with the rotating frame 61. The rotating frame 61 is rotatably connected between the mounting frames 1. The rotating frame 61 is connected with a loading frame 63. A weighing sensor 62 for accurately weighing is arranged between the rotating frame 61 and the loading frame 63. And the weighing sensor 62 is connected with a controller to realize the real-time monitoring and recording of the material weight.

[0024] As Figure 4 and Figure 5 shown, the separating component includes a cylinder 7, a guide rod 71 and a sealing half funnel 72. Cylinders 7 are installed on the left and right sides in the middle of the mounting frame 1. A guide rod 71 is connected to the piston rod of the cylinder 7. The guide rod 71 passes through the mounting frame 1 and is connected with a sealing half funnel 72. Two sealing half funnels 72 form a funnel with a sealed bottom. The diameter of the top opening of the funnel is larger than the inner diameter of the bottom of the guide pipe 4. When the air pump 3 is closed, the volume formed by the two sealing half funnels 72 is larger than the volume of the materials that may remain in the suction hopper 2.

[0025] The staff turns on the air pump 3, and the air in the material suction hopper 2 is gradually pumped out through the air pump 3. After the gas is discharged through the exhaust pipe 31, the inside of the material suction hopper 2 approaches a vacuum state. At this time, air is inhaled through the material suction pipe 21. Since the material suction pipe 21 is inserted into the material, the material suction pipe 21 sucks the air and the material into the material suction hopper 2 together. After the material is inhaled, due to its own gravity, it falls along the material guide pipe 4, and the air is discharged through the exhaust pipe 31 again. When part of the material moves upward with the air, it will be blocked by the blocking net 5 and thus will not enter the air pump 3. After hitting the blocking net 5, the material drops again and falls into the loading frame 63 along the material guide pipe 4. As the material in the loading frame 63 gradually increases, the weighing sensor 62 sends weight information to the control end while weighing. When the weight of the material in the loading frame 63 reaches three - quarters of the threshold value, the controller starts the cylinder 7. The cylinder 7 pushes the guide rod 71 to move towards the middle, making the two sealing half - funnels 72 approach each other. Since the two sealing half - funnels 72 form a funnel with a sealed bottom, the approaching sealing half - funnels 72 gradually narrow the range through which the material passes. After part of the material hits the sealing half - funnels 72, it can still fall into the loading frame 63, and part of the material bounces back and forth between the two sealing half - funnels 72. When the weight of the material in the loading frame 63 reaches the threshold value, the two sealing half - funnels 72 close, thus blocking the material from continuing to fall. The air pump 3 is turned off and the motor 6 is started. When the air pump 3 is turned off, the material suspended in the material suction hopper 2 or sticking to the blocking net 5 falls vertically and all falls into the funnel formed by the two sealing half - funnels 72. The motor 6 flips the rotating frame 61 by 180 degrees to complete the unloading of the loading frame 63. At this time, another empty loading frame 63 has been automatically aligned with the sealing half - funnels 72. Subsequently, the motor 6 is turned off, and the rotating frame 61 flips 180 degrees to complete the unloading. After that, the air pump 3 and the cylinder 7 are turned on to prepare for the next round of feeding. The air pump 3 pumps out the air in the material suction hopper 2 to continue feeding. The cylinder 7 pulls the sealing half - funnels 72 to move to both sides through the guide rod 71, and the material stored in the sealing half - funnels 72 falls into the loading frame 63. When the weight of the material in the loading frame 63 reaches three - quarters of the threshold value, the above steps are repeated to complete weighing and discharging. When stopping work, the staff turns off the air pump 3, the motor 6 and the cylinder 7.

[0026] As Figure 4 and Figure 5 shown, it further includes a blocking plate 8 and a scraping frame 81. The blocking plate 8 is connected to the sealing half - funnel 72. The heights of the two blocking plates 8 are different. The scraping frame 81 is connected to the inner sides of the left and right ends of the mounting frame 1. The scraping frame 81 is slidably connected to the blocking plate 8. When the two sealing half - funnels 72 close, there is a through - hole left between the two blocking plates 8 so that the material accumulated on the blocking plate 8 can gradually pass through and fall into the sealing half - funnel 72. When the two sealing half - funnels 72 separate, a circular hole is formed between the two blocking plates 8, and the diameter of the circular hole is equal to the inner diameter of the bottom of the material guide pipe 4.

[0027] As Figure 5 shown, it further includes a tassel 9. A tassel 9 for preventing material from splashing is connected to the bottom of the sealing semi-funnel 72.

[0028] During the process of the sealing semi-funnel 72 closing towards the middle, the blocking plate 8 moves along with the sealing semi-funnel 72, and the through-hole between the two blocking plates 8 gradually shrinks to block the material, thereby further slowing down the falling speed of the material. When the sealing semi-funnel 72 is closed, there is a through-hole between the two blocking plates 8 so that the material accumulated on the blocking plate 8 can gradually pass through and fall into the sealing semi-funnel 72. After the material accumulates on the blocking plate 8, the material can fall into the sealing semi-funnel 72 through the through-hole. During the process of the sealing semi-funnel 72 moving towards both sides to release the material, the scraping frame 81 remains stationary. When the surface of the blocking plate 8 contacts the scraping frame 81, the scraping frame 81 effectively pushes all the residual material on the blocking plate 8 out to ensure that the material can smoothly fall into the loading frame 63. Moreover, after the material collides with the bottom of the sealing semi-funnel 72 and moves around, when the material contacts the tassel 9, the tassel 9 absorbs the kinetic energy of the material movement for buffering, and then the material falls vertically to ensure that all the material falls into the loading frame 63.

[0029] The above are only examples of the present invention and are not used to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the known prior art of those skilled in the art.
