DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides two technical solutions:

[0026] Figure 1-Figure 3 The first embodiment is shown: a heavy calcium carbonate grinding quantitative conveying device, comprising a mounting frame 1, the inner side of which is provided with a conveying mechanism 2 for quantitatively conveying the heavy calcium carbonate after crushing, and the conveying mechanism 2 comprises:

[0027] The quantitative component 21 is arranged on the inner side of the mounting frame 1 for quantitatively conveying heavy calcium carbonate. The quantitative component 21 includes a quantitative cylinder 211 fixedly mounted on the inner side of the mounting frame 1. A solenoid valve tube 212 is fixedly mounted on the top surface of the quantitative cylinder 211. A control module 214 and a DC motor 215 are fixedly mounted on the front side of the quantitative cylinder 211. The model of the control module 214 is L298N and is used to control the rotation of the DC motor 215 and the opening and closing of the solenoid valve tube 212. A movable plate 213 is movably mounted inside the quantitative cylinder 211. A weighing sensor 218 is fixedly mounted on the top surface of the movable plate 213. The model of the weighing sensor 218 is QSEB-A / -SS-25klb and is used to weigh heavy calcium carbonate. A material storage box 217 is fixedly mounted on the top surface of the weighing sensor 218. A feed trough 216 is provided on the top surface of the material storage box 217.

[0028] The discharging assembly 22 is arranged on the bottom surface of the metering cylinder 211 and is used for guiding and conveying heavy calcium carbonate;

[0029] The crushing assembly 23 is arranged on the top surface of the metering cylinder 211 and is used to crush large pieces of heavy calcium carbonate. The outer side of the storage box 217 is closely attached to the inner side of the metering cylinder 211. The bottom end of the electromagnetic valve tube 212 penetrates the top surface of the metering cylinder 211 and extends to the inside of the metering cylinder 211. The material discharge can be controlled by the electromagnetic valve tube 212. The output end of the DC motor 215 movably penetrates the front side of the metering cylinder 211 and is fixedly installed on the front side of the movable plate 213. Starting the DC motor 215 can drive the movable plate 213 to rotate. When the movable plate 213 drives the storage box 217 to rotate, the movable plate 213 rotates. When the box 217 is turned over, the heavy calcium carbonate inside the storage box 217 will be discharged through the feed slot 216, and the discharge assembly 22 includes a guide box 221 fixedly installed on the bottom surface of the metering cylinder 211, and a discharge port 223 is provided on the bottom surface of the guide box 221. A guide plate 222 is fixedly installed on the front side of the bottom surface of the metering cylinder 211, and the guide plate 222 is installed at an angle. The guide plate 222 is located below the discharge port 223, and the heavy calcium carbonate will fall out from the discharge port 223 and fall into the grinding device for subsequent grinding under the guidance of the guide plate 222.

[0030] The heavy calcium carbonate can be quantitatively transported by the electromagnetic valve tube 212 and the weighing sensor 218. When in use, the control module 214 presets an appropriate weight, and then the control module 214 opens the electromagnetic valve tube 212 to allow the heavy calcium carbonate to fall into the storage box 217 through the feed trough 216. At this time, the weighing sensor 218 weighs the heavy calcium carbonate inside the storage box 217. When the preset weight is reached, the control module 214 closes the electromagnetic valve tube 212 and starts the DC motor 215 to drive the movable plate 213 to rotate one circle. When the movable plate 213 drives the storage box 217 to turn over, the heavy calcium carbonate inside the storage box 217 will be discharged through the feed trough 216, and then the heavy calcium carbonate will fall into the interior of the grinding device through the guidance of the discharge component 22. It is simple to use and improves the overall working efficiency of the device.

[0031] Figure 1-Figure 2 and Figure 4 A second embodiment is shown, which mainly differs from the first embodiment in that: the crushing assembly 23 includes two mounting plates 234 fixedly mounted on the top surface of the metering cylinder 211, the top surfaces of the two mounting plates 234 are fixedly mounted with a storage box 231, two crushing rollers 232 are movably mounted inside the storage box 231, two driving motors 233 are fixedly mounted on the left side of the storage box 231, the top end of the solenoid valve tube 212 passes through the bottom surface of the crushing roller 232 and extends to the interior of the storage box 231, the output ends of the two driving motors 233 movably pass through the left side of the storage box 231 and are fixedly mounted on the left ends of the two crushing rollers 232, and starting the two driving motors 233 can drive the two crushing rollers 232 to crush large pieces of heavy calcium carbonate.

[0032] The large pieces of heavy calcium carbonate can be crushed by the crushing roller 232. When in use, the heavy calcium carbonate is placed in the storage box 231, and then the driving motor 233 is started to drive the crushing roller 232 to rotate to the opposite side to crush the large pieces of heavy calcium carbonate, thereby preventing the large pieces of heavy calcium carbonate from falling into the quantitative component 21 and causing blockage, which has good practicality.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0034] When in use, the user connects the device to the power supply, and then presets an appropriate weight through the control module 214, and then puts the heavy calcium carbonate into the storage box 231. At this time, the drive motor 233 is started to drive the crushing roller 232 to rotate to the opposite side to crush the heavy calcium carbonate. The crushed heavy calcium carbonate will fall into the storage box 217 through the electromagnetic valve tube 212 and the feed trough 216. At this time, the weighing sensor 218 will weigh the heavy calcium carbonate inside the storage box 217. When the preset weight is reached, the control module 214 will close the electromagnetic valve tube 212 and start the DC motor 215 to drive the movable plate 213 to rotate one circle. When the movable plate 213 drives the storage box 217 to turn over, the heavy calcium carbonate inside the storage box 217 will be discharged through the feed trough 216 and fall into the inside of the quantitative cylinder 211. Then the heavy calcium carbonate will fall out through the drive motor 233 and fall into the inside of the grinding device through the guidance of the guide plate 222 for subsequent grinding.
