When the movable plate 306 contacts with the switch 311, the first electromagnetic valve 308 is opened, the second electromagnetic valve 310 is closed, as the liquid in the second liquid storage tank 302 continues to increase, the liquid in the second liquid storage tank 302 enters the third liquid storage tank 305 through the second communicating pipe 304, the liquid presses the piston plate of the third liquid storage tank 305, the piston plate of the third liquid storage tank 305 drives the fixing frame 203 to move upwards through the connecting rod 110, the fixing frame 203 drives the movable ring 204 to move upwards, the movable ring 204 presses the rotary plate 202 through the second limiting groove 205, the rotary plate 202 of the circumferential array is gradually closed, when the rotary plate 202 is in a horizontal state, the piston rods of the first liquid storage tank 301 and the third liquid storage tank 305 stop moving, at the moment, the material amount in the material storage tank 105 does not reach the required material amount, an operator turns on the motor 207 and turns off the electromagnet 406, the output shaft of the motor 207 drives the auger 208 to rotate, the material above the rotary plate 202 is fed into the material storage tank 105 through the feeding pipe 209, when the material amount in the material storage tank 105 is measured by the weighing device 109, the material amount in the material storage tank 105 automatically reaches the required amount of the motor 207, the material storage tank 105 stops, and the material storage tank is accurately closed, and the material storage tank 105 is accurately stopped.
When an operator de-energizes the electromagnet 406, the electromagnet 406 loses magnetic force, the electromagnet 406 does not attract the mounting ring 405 any more, under the action of spring force between the mounting ring 405 and the electromagnet 406, the mounting ring 405 drives the adjacent second wedge blocks 410 to move upwards through the mounting rod, the second wedge blocks 410 squeeze the adjacent first wedge blocks 408, so that the two symmetrically distributed first wedge blocks 408 move back, the two symmetrically distributed second limiting rods 407 drive the adjacent clamping blocks 409 to move back, the spring between the first wedge blocks 408 and the connecting frame 111 is compressed, and the clamping blocks 409 outwards extend.
When the weighing device 109 detects that the amount of the material in the storage barrel 105 reaches the required amount, an operator starts the electric push rod 112, the telescopic end of the electric push rod 112 drives the movable piece 1131 to move downwards, the movable piece 1131 drives the base 113 to move downwards, the base 113 loses contact with the storage barrel 105, and the material in the storage barrel 105 moves downwards along the conical surface of the base 113, so that the material flows out of the lower end of the outer shell 101.
In the process that the materials in the storage barrel 105 move downwards along the conical surface of the base 113, as the materials in the storage barrel 105 are reduced, the gravity born by the storage barrel 105 is gradually reduced, under the action of the spring force sleeved by the first limiting rod 107, the first limiting rod 107 drives the storage barrel 105 to move upwards through the fixing plate 106, and the storage barrel 105 drives the second limiting rod 407 and the clamping block 409 to move upwards through the connecting frame 111.
In the process that the first stop lever 107 drives the material storage barrel 105 to move upwards through the fixed plate 106, the first stop lever 107 drives the piston rod of the first liquid storage tank 301 to move upwards through the protective shell 108, and because the first electromagnetic valve 308 is in an open state at this time, the second electromagnetic valve 310 is in a closed state, the one-way valve of the second communicating pipe 304 enables liquid in the third liquid storage tank 305 to not pass through the second communicating pipe 304 and enter the second liquid storage tank 302, the total amount of liquid in the third liquid storage tank 305 is unchanged, the liquid in the second liquid storage tank 302 is reduced, and the piston rod of the second liquid storage tank 302 drives the movable plate 306 to move downwards.
When fly leaf 306 and switch 311 are about to contact, fixture block 409 and dog 411 contact, dog 411 carries out the spacing to fixture block 409, make fixture block 409 unable to continue to move upwards, storage cylinder 105 and first gag lever post 107 stop upwards moving, after the material in the storage cylinder 105 all leaves, the flexible end of operating personnel control electric putter 112 upwards moves, electric putter 112 flexible end passes through moving part 1131 and drives base 113 upwards movement, when base 113 and storage cylinder 105 contact, electric putter 112 closes, dog 411 carries out the spacing to fixture block 409, prevent that the material in the storage cylinder 105 from not all leaving, the rotor plate 202 opens, new material gets into in the storage cylinder 105, the material volume that causes storage cylinder 105 single storage is inaccurate.
When the material needs to be weighed again, the operator repeats all the operations described above.
Example 2: on the basis of embodiment 1, as shown in fig. 10, 11 and 13, the scraper assembly further comprises a scraper assembly, the scraper assembly comprises a fixed shell 401, the fixed shell 401 is fixedly connected between two connecting frames 111 which are symmetrically distributed through a mounting frame, the fixed shell 401 is located outside the telescopic end of the electric push rod 112, the fixed shell 401 is provided with a spiral third limit groove 402, a limiting block 403 which is in limit sliding fit with the spiral third limit groove 402 is fixedly connected with a movable piece 1131, the movable piece 1131 drives a base 113 to rotate, two first scrapers 501 which are symmetrically distributed are in circumferential sliding connection with the inner wall of the storage cylinder 105, the first scrapers 501 are attached to the inner wall of the storage cylinder 105, the two first scrapers 501 which are symmetrically distributed are slidably connected with a second scraper 502, the second scraper 502 is fixedly connected with the base 113, and the base 113 drives the first scrapers 501 and the second scrapers 502 to rotate, so that the first scrapers 501 and the second scrapers 502 clean the inner wall of the storage cylinder 105.
In the process that the movable piece 1131 drives the base 113 to move downwards, the limiting block 403 is in limiting sliding fit with the spiral third limiting groove 402, the limiting block 403 drives the movable piece 1131 and the base 113 to rotate, and the base 113 throws out materials contacted with the movable piece 1131 outwards, so that the materials are rapidly separated from the storage cylinder 105.
In the process that the movable piece 1131 drives the base 113 to move downwards, the base 113 drives the second scraping plate 502 to move downwards, when the limiting block 403 drives the movable piece 1131 and the base 113 to rotate, the base 113 drives the first scraping plate 501 and the second scraping plate 502 to rotate, and the first scraping plate 501 and the second scraping plate 502 scrape off materials attached to the inner wall of the storage barrel 105, so that the materials are prevented from remaining in the storage barrel 105, and the material quantity is inaccurate.
