Description

Technical Field

[0001] The invention relates to the technical field of weighing, and in particular to an automatic loading quantitative weighing hopper. Background Art

[0002] At present, when loading materials, it is necessary to transport the materials (such as wood chips, etc.) into the weighing hopper. When the weight of the materials in the weighing hopper reaches a certain amount, the material transportation is closed, and the materials in the hopper are discharged into the carriage, thereby completing the weighing and loading of the materials.

[0003] When the amount of material in the weighing hopper reaches a certain amount, the material conveying needs to be closed, and the material in the hopper needs to be discharged before the next feeding and loading can be carried out. This weighing method has low weighing efficiency for materials and is time-consuming. Therefore, an automatic loading quantitative weighing hopper is proposed to improve the weighing efficiency and loading efficiency. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides an automated loading quantitative weighing hopper to improve weighing efficiency and loading efficiency.

[0005] The technical solution adopted by the present invention to solve the technical problem is an automatic loading quantitative weighing hopper, comprising a vertically arranged fixed seat, four groups of penetrating feeding holes are arranged above the fixed seat, a feeding box is arranged on the upper surface of the fixed seat, the lower surface of the feeding box is in sliding contact with the upper surface of the fixed seat, and a penetrating discharge hole is arranged in the feeding box;

[0006] A cleaning structure is provided in the feed hole, a driving structure is provided in the fixed seat, the driving structure is used to drive the feed box to rotate and drive the cleaning structure, and an electrically controlled discharge structure is provided at the lower end of the feed hole.

[0007] By adopting the above technical solution, when loading is required, the material is transported to the feed box, and after entering the feed box, the material enters a group of feed holes through the discharge hole, and the material is stored by the feed hole. When the amount of material in the feed hole reaches a certain weight, the drive structure is first turned on, and then the electric control discharge structure is turned on. The material in the feed hole is discharged by the electric control discharge structure and falls into the carriage of the transport vehicle, thereby completing the weighing and loading of the material;

[0008] The feed box is driven to rotate by the driving structure. When the feed box rotates, it slides and contacts with the upper surface of the fixed seat to prevent the material from being discharged through the discharge holes. When the feed box rotates to a certain position, the feed box corresponds to another set of feed holes. At the same time, the material in the feed box will enter another set of feed holes through the discharge holes again. When the amount of material in the other set of feed holes reaches a certain weight again, the driving structure and the electronically controlled discharge structure are turned on again. This operation is repeated. With the four sets of feed holes, the weighing efficiency of the material and the loading efficiency can be improved.

[0009] The driving structure drives the cleaning structure in the corresponding feed hole to work. The cleaning structure can transport the material in the feed hole downward to prevent material blockage. At the same time, the cleaning structure can clean the inner wall of the feed hole, thereby further improving the loading efficiency and convenience.

[0010] Specifically, the electrically controlled discharging structure includes several groups of discharging barrels fixedly installed on the lower surface of the fixed seat, the discharging barrels correspond to the feeding holes, the discharging barrels are funnel-shaped, and the bottom of the discharging barrel is hinged with a swing plate through a first torsion spring. An electromagnet is provided on the upper surface of the swing plate. The electromagnet is magnetically adsorbed to the lower end of the discharging barrel in an initial state.

[0011] By adopting the above technical solution, after the material enters the feed box, it enters into a group of feed holes through the discharge hole. When the material enters the feed hole, it falls into the discharge barrel. As the material accumulates, when the amount of material in the discharge barrel and the feed hole reaches a certain amount, the electromagnet is temporarily turned off so that the electromagnet on the swing plate and the discharge barrel are no longer adsorbed. At this time, the material in the discharge barrel and the feed hole will drive the swing plate to swing, so that the material is discharged through the bottom of the discharge barrel, and the falling material will fall into the car, thereby completing the weighing and loading of the material;

[0012] When the materials in a group of discharge barrels and the feed hole are discharged, the swing plate is driven to swing and reset by the reset effect of the first torsion spring. After the swing plate swings and resets to a certain position, the bottom of the discharge barrel can be blocked again by the magnetic adsorption of the electromagnet and the discharge barrel.

[0013] It should be pointed out that the first torsion spring is a damping torsion spring, which can facilitate the complete discharge of materials in the discharge barrel and the feed hole during the swinging and resetting process of the swing plate, thereby ensuring the transportation of the materials.

[0014] Specifically, the cleaning structure includes a slot, the slot is provided at the inner upper part of the feed hole, a horizontal rotating ring is rotatably connected in the slot, a first tooth structure is provided on the outer side of the rotating ring, and the first tooth structure is meshed with the driving structure for transmission;

[0015] The lower surface of the rotating ring is rotatably connected with a plurality of groups of circumferentially distributed fixed rods, the fixed rods are vertically arranged, the lower surfaces of the fixed rods are fixedly connected with vertically arranged first spiral cleaning rods, the first spiral cleaning rods are in sliding contact with the inner wall of the feed hole, the lower ends of the first spiral cleaning rods are fixedly connected with obliquely arranged second spiral cleaning rods, the second spiral cleaning rods are elastic cleaning rods, and the second spiral cleaning rods are in sliding contact with the inner wall of the discharge barrel;

[0016] A gear is fixedly connected to the upper portion of the fixing rod, and a second tooth structure is provided on the inner wall of the feeding hole, and the second tooth structure is meshed with the gear for transmission.

[0017] By adopting the above technical scheme, when the amount of material in a group of feed holes reaches a certain weight, the driving structure is turned on, and the driving structure drives the feed box to rotate a certain angle when working, thereby stopping the feeding of the current feed hole and ensuring the accuracy of the feeding amount of the feed hole. After the feeding of the feed hole stops, the electromagnet can be temporarily closed to carry out the discharging work of the discharging barrel; at the same time, when the driving structure rotates, it meshes with the first tooth structure to drive the first tooth structure and the rotating ring to rotate synchronously, and when the rotating ring rotates, it drives the fixed rod and the first spiral cleaning rod and the second spiral cleaning rod to revolve. The revolution of the first spiral cleaning rod and the second spiral cleaning rod can be used to clean the inner wall of the feed hole and the discharging barrel, so as to prevent the material from accumulating on the inner wall of the feed hole and the discharging barrel during the falling process, thereby improving the convenience of material transportation;

[0018] When the rotating ring drives the fixed rod to rotate, the gear and the second tooth structure are meshed to drive the fixed rod to rotate. When the fixed rod rotates, it drives the first spiral cleaning rod to rotate. When the first spiral cleaning rod rotates, it drives the second spiral cleaning rod to rotate. The rotation of the first spiral cleaning rod and the second spiral cleaning rod produces a downward conveying effect, which facilitates the conveying of materials in the feed hole and the discharge barrel, improves the material conveying efficiency and the loading efficiency, and prevents the material from clogging the bottom of the discharge barrel, thereby further improving the convenience of use.

[0019] It should be noted that the second spiral cleaning rod of the present invention is an elastic structure, so that the second spiral cleaning rod can be pressed and contacted with the inner wall of the discharge barrel, and ensure that when the first spiral cleaning rod revolves in the feed hole, the second spiral cleaning rod can always be pressed and contacted with the inner wall of the discharge barrel, so as to ensure the transportation stability of the material in the discharge barrel;

[0020] It should be noted that the rotating ring described in the present invention is connected to the slotted damping type rotation.

[0021] Specifically, the driving structure includes a mounting groove opened on the upper surface of the fixed seat, the mounting groove is located between several groups of feed holes, a driving motor is arranged in the mounting groove, the output shaft of the driving motor is vertically arranged, a second torsion spring is fixedly connected to the output shaft, a half tooth is fixedly connected to the upper surface of the second torsion spring, the slot is connected to the mounting groove, the half tooth is meshed with a group of first tooth structures in an initial state, and the upper end of the output shaft is fixedly connected to the lower surface of the feed box.

[0022] By adopting the above technical solution, when the amount of material in a group of feed holes reaches a certain weight, the drive motor is automatically turned on to rotate a certain angle, and the feed box is driven to rotate by the output shaft of the drive motor, thereby stopping the feeding of the current feed hole, ensuring the accuracy of the feed amount of the feed hole, and after the feed hole stops feeding, the electromagnet can be temporarily closed to carry out the discharging work of the discharging barrel, and after the feed box rotates to a certain position, the discharge holes of the feed box correspond to another group of feed holes at this time;

[0023] When the output shaft of the driving motor rotates rapidly, it drives the second torsion spring to rotate. When the second torsion spring rotates, it drives the half-tooth to rotate. When the half-tooth rotates, it corresponds to a first tooth structure in a corresponding feed hole. Since the rotating ring rotates in a damping manner in the slot, the half-tooth cannot drive the rotating ring to rotate rapidly, so that the second torsion spring can store force. When the driving motor drives the feed box to rotate to a certain position, the half-tooth is driven to rotate by the reset effect of the second torsion spring and meshes with the first tooth structure for transmission, thereby driving the rotating ring to rotate slowly. When the rotating ring rotates, it drives the first spiral cleaning rod and the second spiral cleaning rod to rotate synchronously, so as to clean and transport the materials in the feed hole and the discharge barrel.

[0024] It should be pointed out that the number of the first spiral cleaning rod and the second spiral cleaning rod in each feed hole can be four groups, so as to further facilitate the transportation and cleaning of the materials in the feed hole and the discharge barrel.

[0025] Specifically, a pressure detection structure is provided on the upper surface of the swing plate. The pressure detection structure includes a push switch. The push switch is installed on the upper surface of the swing plate. The push switch is used to control the drive motor and the electromagnet.

[0026] By adopting the above technical solution, when the material enters the feed hole and falls into the discharge barrel, when the amount of material in the discharge barrel and the feed hole reaches a certain amount, the material is squeezed to turn on the press switch. After the press switch is turned on, the drive motor is automatically turned on and rotated to a certain angle, and then the electromagnet is turned off, so as to facilitate the transportation of the material in the feed hole and the discharge barrel to the car to complete the loading; at the same time, it is convenient to drive the feed box to rotate and transport the material to another group of feed holes, thereby improving the weighing efficiency and loading efficiency.

[0027] Specifically, a slope toward the discharge hole is provided in the feed box.

[0028] By adopting the above technical solution, when the material enters the feed box, the slope can facilitate the material to pass through the discharge hole into the corresponding feed hole, thereby improving the convenience and efficiency of feeding.

[0029] Specifically, a vertically arranged material blocking cylinder is fixedly connected above the feed box.

[0030] By adopting the above technical solution, during the rotation of the feed box, the feed box slides in contact with the upper surface of the fixed seat. At this time, the material cannot be discharged through the discharge hole. The material blocking cylinder can increase the storage capacity of the feed box and prevent the material from overflowing from the edge of the feed box, thereby further improving the convenience of use.

[0031] Beneficial effects of the present invention:

[0032] (1) The automatic loading quantitative weighing hopper described in the present invention starts the driving structure when the amount of material in a group of feed holes reaches a certain weight. When the driving structure works, it drives the feed box to rotate a certain angle, thereby stopping the feeding of the current feed hole. After the feed box rotates to a certain position, the discharge holes of the feed box correspond to another group of feed holes. At the same time, the material in the feed box will enter another group of feed holes through the discharge holes again. This operation is repeated. With the four groups of feed holes, the weighing efficiency of the material and the loading efficiency can be improved.

[0033] (2) The present invention describes an automated loading quantitative weighing hopper. When the feed box rotates to a certain position, the discharge holes of the feed box correspond to another set of feed holes. At the same time, the half teeth rotate and mesh with the first tooth structure to drive the first tooth structure and the rotating ring to rotate synchronously. When the rotating ring rotates, it drives the fixed rod and the first spiral cleaning rod and the second spiral cleaning rod to revolve. The revolution of the first spiral cleaning rod and the second spiral cleaning rod can clean the feed hole and the inner wall of the discharge barrel, preventing the material from accumulating on the feed hole and the inner wall of the discharge barrel during the falling process, thereby improving the convenience of material transportation.

[0034] (3) The automatic loading quantitative weighing hopper described in the present invention, when the rotating ring drives the fixed rod to rotate, the fixed rod is driven to rotate by the meshing transmission of the gear and the second tooth structure, and the fixed rod drives the first spiral cleaning rod to rotate when the fixed rod rotates, and the first spiral cleaning rod drives the second spiral cleaning rod to rotate when the first spiral cleaning rod rotates, and a downward conveying effect is generated by the rotation of the first spiral cleaning rod and the second spiral cleaning rod, thereby facilitating the conveying of materials in the feed hole and the discharge barrel, improving the material conveying efficiency and the loading efficiency, and preventing the material from clogging the bottom of the discharge barrel.

DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] In order to improve the weighing efficiency and the loading efficiency, as an embodiment of the present invention, Figure 1 , Figure 2 , Fig.10As shown, an automatic loading quantitative weighing hopper of the present invention comprises a vertically arranged fixed seat 1, four groups of penetrating feeding holes 2 are arranged above the fixed seat 1, a feeding box 3 is arranged on the upper surface of the fixed seat 1, the lower surface of the feeding box 3 is in sliding contact with the upper surface of the fixed seat 1, and a penetrating discharge hole 4 is arranged in the feeding box 3;

[0049] A cleaning structure is provided in the feed hole 2, a driving structure is provided in the fixed seat 1, and the driving structure is used to drive the feed box 3 to rotate and drive the cleaning structure. An electrically controlled discharge structure is provided at the lower end of the feed hole 2.

[0050] When in use, when loading is required, the material is transported to the feed box 3. After entering the feed box 3, the material enters a group of feed holes 2 through the discharge hole 4, and the material is stored by the feed hole 2. When the amount of material in the feed hole 2 reaches a certain weight, the drive structure is first turned on, and then the electric control discharge structure is turned on. The material in the feed hole 2 is discharged by the electric control discharge structure and falls into the carriage of the transport vehicle, thereby completing the weighing and loading of the material;

[0051] The feed box 3 is driven to rotate by the driving structure. When the feed box 3 rotates, it slides and contacts with the upper surface of the fixed seat 1 to prevent the material from being discharged through the discharge hole 4. When the feed box 3 rotates to a certain position, the feed box 3 corresponds to another group of feed holes 2. At the same time, the material in the feed box 3 will pass through the discharge hole 4 again and enter another group of feed holes 2. When the amount of material in the other group of feed holes 2 reaches a certain weight again, the driving structure and the electronically controlled discharge structure are turned on again. This operation is repeated. In combination with the four groups of feed holes 2, the weighing efficiency of the material and the loading efficiency can be improved.

[0052] The driving structure drives the cleaning structure in the corresponding feed hole 2 to work. The cleaning structure can transport the material in the feed hole 2 downward to prevent material blockage. At the same time, the cleaning structure can clean the inner wall of the feed hole 2, thereby further improving the loading efficiency and convenience.

[0053] In order to facilitate the discharge of the material in the feed hole 2, for example, Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig.10 As shown, the present invention also includes that the electrically controlled discharging structure includes a plurality of discharging barrels 5 fixedly mounted on the lower surface of the fixed seat 1, the discharging barrel 5 corresponds to the feeding hole 2, the discharging barrel 5 is funnel-shaped, and the bottom of the discharging barrel 5 is hinged with a swing plate 7 through a first torsion spring 6, and an electromagnet 8 is provided on the upper surface of the swing plate 7, and the electromagnet 8 is magnetically adsorbed to the lower end of the discharging barrel 5 in the initial state.

[0054] When in use, the material enters the feed box 3 and then enters a group of feed holes 2 through the discharge hole 4. When the material enters the feed hole 2, it falls into the discharge barrel 5. As the material accumulates, when the amount of material in the discharge barrel 5 and the feed hole 2 reaches a certain amount, the electromagnet 8 is temporarily closed, so that the electromagnet on the swing plate 7 and the discharge barrel 5 are no longer adsorbed. At this time, the material in the discharge barrel 5 and the feed hole 2 will drive the swing plate 7 to swing, so that the material is discharged through the bottom of the discharge barrel 5, and the falling material will fall into the car, thereby completing the weighing and loading of the material;

[0055] When the materials in a group of discharge barrels 5 and the feed hole 2 are discharged, the swing plate 7 is driven to swing and reset by the reset effect of the first torsion spring 6. After the swing plate 7 swings and resets to a certain position, the bottom of the discharge barrel 5 can be blocked again by the magnetic adsorption of the electromagnet 8 and the discharge barrel 5.

[0056] It should be pointed out that the first torsion spring 6 is a damping torsion spring, which can facilitate the complete discharge of materials in the discharge barrel 5 and the feed hole 2 during the swinging and resetting process of the swing plate 7, thereby ensuring the transportation of the materials.

[0057] In order to improve the convenience of material transportation, for example, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes that the cleaning structure includes a slot 9, the slot 9 is opened at the inner upper part of the feed hole 2, a horizontal rotating ring 10 is rotatably connected in the slot 9, and a first tooth structure 11 is provided on the outer side of the rotating ring 10, and the first tooth structure 11 is meshed with the driving structure for transmission;

[0058] The lower surface of the rotating ring 10 is rotatably connected with a plurality of groups of circumferentially distributed fixed rods 12, the fixed rods 12 are vertically arranged, and the lower surfaces of the fixed rods 12 are fixedly connected with vertically arranged first spiral cleaning rods 13, the first spiral cleaning rods 13 are in sliding contact with the inner wall of the feed hole 2, and the lower ends of the first spiral cleaning rods 13 are fixedly connected with obliquely arranged second spiral cleaning rods 14, the second spiral cleaning rods 14 are elastic cleaning rods, and the second spiral cleaning rods 14 are in sliding contact with the inner wall of the discharge barrel 5;

[0059] A gear 15 is fixedly connected to the upper portion of the fixing rod 12 , and a second tooth structure 16 is disposed on the inner wall of the feeding hole 2 . The second tooth structure 16 is meshed with the gear 15 for transmission.

[0060] When in use, when the amount of material in a group of feed holes 2 reaches a certain weight, the driving structure is turned on. When the driving structure works, it drives the feed box 3 to rotate a certain angle, thereby stopping the feeding of the current feed hole 2 to ensure the accuracy of the feeding amount of the feed hole 2. After the feeding of the feed hole 2 stops, the electromagnet 8 can be temporarily closed to carry out the discharging work of the discharging barrel 5; after the feed box 3 rotates to a certain position, the discharge holes 4 of the feed box 3 correspond to another group of feed holes 2. At the same time, when the driving structure rotates, it meshes with the first tooth structure 11 to drive the first tooth structure 11 and the rotating ring 10 to rotate synchronously. When the rotating ring 10 rotates, it drives the fixed rod 12 and the first spiral cleaning rod 13 and the second spiral cleaning rod 14 to revolve. The revolution of the first spiral cleaning rod 13 and the second spiral cleaning rod 14 can clean the inner wall of the feed hole 2 and the discharging barrel 5 to prevent the material from accumulating on the inner wall of the feed hole 2 and the discharging barrel 5 during the falling process, thereby improving the convenience of material transportation;

[0061] When the rotating ring 10 drives the fixed rod 12 to rotate, the gear 15 and the second tooth structure 16 mesh with each other to drive the fixed rod 12 to rotate. When the fixed rod 12 rotates, it drives the first spiral cleaning rod 13 to rotate. When the first spiral cleaning rod rotates, it drives the second spiral cleaning rod 14 to rotate. The rotation of the first spiral cleaning rod 13 and the second spiral cleaning rod 14 produces a downward conveying effect, thereby facilitating the conveying of materials in the feed hole 2 and the discharge barrel 5, improving the material conveying efficiency and the loading efficiency, and preventing the material from clogging the bottom of the discharge barrel 5, thereby further improving the convenience of use;

[0062] It should be noted that the second spiral cleaning rod 14 of the present invention is an elastic structure, so that the second spiral cleaning rod 14 can be pressed and contacted with the inner wall of the discharge barrel 5, and ensure that when the first spiral cleaning rod 13 revolves in the feed hole 2, the second spiral cleaning rod 14 can always be pressed and contacted with the inner wall of the discharge barrel 5, thereby ensuring the transportation stability of the material in the discharge barrel 5;

[0063] It should be pointed out that the rotating ring 10 of the present invention is connected to the slot 9 in a damping rotation manner.

[0064] In order to facilitate driving the feed box 3 to rotate, for example, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9As shown, the present invention also includes that the driving structure includes a mounting groove 17 opened on the upper surface of the fixed seat 1, the mounting groove 17 is located between several groups of feed holes 2, a driving motor 18 is arranged in the mounting groove 17, the output shaft 19 of the driving motor 18 is vertically arranged, a second torsion spring 20 is fixedly connected to the output shaft 19, a half tooth 21 is fixedly connected to the upper surface of the second torsion spring 20, the slot 9 is connected to the mounting groove 17, the half tooth 21 is meshed with a group of first tooth structures 11 in the initial state, and the upper end of the output shaft 19 is fixedly connected to the lower surface of the feed box 3.

[0065] When in use, when the amount of material in a group of feed holes 2 reaches a certain weight, the drive motor 18 is automatically turned on to rotate a certain angle, and the output shaft 19 of the drive motor 18 is rotated to drive the feed box 3 to rotate, thereby stopping the feeding of the current feed hole 2 to ensure the accuracy of the feed amount of the feed hole 2. After the feed hole 2 stops feeding, the electromagnet 8 can be temporarily closed to carry out the discharge work of the discharge barrel 5, and after the feed box 3 rotates to a certain position, the discharge hole 4 of the feed box 3 corresponds to another group of feed holes 2;

[0066] When the output shaft 19 of the driving motor 18 rotates rapidly, it drives the second torsion spring 20 to rotate. When the second torsion spring 20 rotates, it drives the half teeth 21 to rotate. When the half teeth 21 rotate, they correspond to a set of first tooth structures 11 in the corresponding feed hole 2. Since the rotating ring 10 rotates in a damped manner in the slot 9, the half teeth 21 cannot drive the rotating ring 10 to rotate rapidly, so that the second torsion spring 20 can store force. When the driving motor 18 drives the feed box 3 to rotate to a certain position, the half teeth 21 are driven to rotate and mesh with the first tooth structure 11 by the reset effect of the second torsion spring 20, thereby driving the rotating ring 10 to rotate slowly. When the rotating ring 10 rotates, it drives the first spiral cleaning rod and the second spiral cleaning rod to rotate synchronously, so as to clean and transport the materials in the feed hole 2 and the discharge barrel 5.

[0067] It should be pointed out that the number of the first spiral cleaning rods 13 and the second spiral cleaning rods 14 in each feed hole 2 can be four groups, so as to further facilitate the transportation and cleaning of the materials in the feed hole 2 and the discharge barrel 5.

[0068] For example, Figure 4 , Figure 7 , Fig.10 As shown, the present invention also includes that a pressure detection structure is provided on the upper surface of the swing plate 7, and the pressure detection structure includes a push switch 22, and the push switch 22 is installed on the upper surface of the swing plate 7, and the push switch 22 is used to control the drive motor 18 and the electromagnet 8.

[0069] During use, when the material enters the feed hole 2 and falls into the discharge barrel 5, when the amount of material in the discharge barrel 5 and the feed hole 2 reaches a certain amount, the material squeezes and turns on the press switch 22. After the press switch 22 is turned on, the drive motor 18 is automatically turned on and rotated to a certain angle, and then the electromagnet 8 is turned off, so as to facilitate the transportation of the material in the feed hole 2 and the discharge barrel 5 to the car to complete the loading; at the same time, it is convenient to drive the feed box 3 to rotate, and transport the material in another group of feed holes 2, thereby improving the weighing efficiency and loading efficiency.

[0070] For example, Figure 4 As shown, the present invention also includes that a slope 23 facing the discharge hole 4 is provided in the feed box 3 .

[0071] During use, after the material enters the feed box 3, the slope 23 can facilitate the material to pass through the discharge hole 4 and enter the corresponding feed hole 2, thereby improving the convenience and efficiency of feeding.

[0072] For example, Figure 1 As shown, the present invention also includes that a vertically arranged material blocking cylinder 24 is fixedly connected above the feed box 3 .

[0073] During use, as the feed box 3 rotates, the feed box 3 slides in contact with the upper surface of the fixed seat 1. At this time, the material cannot be discharged through the discharge hole 4. The material blocking cylinder 24 can increase the storage capacity of the feed box 3 and prevent the material from overflowing from the edge of the feed box 3, thereby further improving the convenience of use.

[0074] When the present invention is in use, when loading is required, the material is transported to the feed box 3, and after entering the feed box 3, the material enters a group of feed holes 2 through the discharge hole 4, and the material is stored by the feed hole 2. When the amount of material in the feed hole 2 reaches a certain weight, the material squeezes and turns on the press switch 22. After the press switch 22 is turned on, the drive motor 18 is automatically turned on to rotate a certain angle, and then the electromagnet 8 is turned off;

[0075] The feed box 3 is driven to rotate by the output shaft 19 of the driving motor 18. After the feed box rotates to a certain position, the discharge hole 4 of the feed box 3 corresponds to another group of feed holes 2, thereby stopping the feeding of the current feed hole 2 to ensure the accuracy of the feeding amount of the feed hole 2. At the same time, the material in the feed box 3 will pass through the discharge hole 4 again and enter another group of feed holes 2. After the feeding of the feed hole 2 stops, the electromagnet 8 can be temporarily closed;

[0076] After the electromagnet 8 is temporarily turned off, the electromagnet on the swing plate 7 and the discharge barrel 5 are no longer attracted. At this time, the materials in the discharge barrel 5 and the feed hole 2 will drive the swing plate 7 to swing, so that the materials are discharged through the bottom of the discharge barrel 5, and the falling materials will fall into the carriage, thereby completing the weighing and loading of the materials;

[0077] When the output shaft 19 of the driving motor 18 rotates rapidly, it drives the second torsion spring 20 to rotate. When the second torsion spring 20 rotates, it drives the half teeth 21 to rotate. When the half teeth 21 rotate, they correspond to a set of first tooth structures 11 in the corresponding feed hole 2. Since the rotating ring 10 rotates in a damping manner in the slot 9, the half teeth 21 cannot drive the rotating ring 10 to rotate rapidly, so that the second torsion spring 20 can store force. When the driving motor 18 drives the feed box 3 to rotate to a certain position, the half teeth 21 are driven to rotate and mesh with the first tooth structure 11 by the reset effect of the second torsion spring 20, thereby driving the rotating ring 10 to rotate slowly. When the rotating ring 10 rotates, it drives the first spiral cleaning rod 13 and the second spiral cleaning rod 14 to rotate synchronously, so as to clean and transport the materials in the feed hole 2 and the discharge barrel 5.

[0078] When the rotating ring 10 drives the fixed rod 12 to rotate, the gear 15 and the second tooth structure 16 are meshed to drive the fixed rod 12 to rotate. When the fixed rod 12 rotates, it drives the first spiral cleaning rod 13 to rotate. When the first spiral cleaning rod 13 rotates, it drives the second spiral cleaning rod 14 to rotate. The rotation of the first spiral cleaning rod 13 and the second spiral cleaning rod 14 produces a downward conveying effect, thereby facilitating the conveying of materials in the feed hole 2 and the discharge barrel 5, improving the material conveying efficiency and the loading efficiency, and preventing the material from clogging the bottom of the discharge barrel 5, thereby further improving the convenience of use;

[0079] When the materials in a group of discharge barrels 5 and feed holes 2 are discharged, the swing plate 7 is driven to swing and reset by relying on the reset effect of the first torsion spring 6. After the swing plate 7 swings and resets to a certain position, the bottom of the discharge barrel 5 can be sealed again by relying on the magnetic adsorption of the electromagnet 8 and the discharge barrel 5. This operation is repeated in combination with four groups of feed holes 2 to improve the weighing efficiency of the materials and the loading efficiency.
