[0023] Example 1:

[0024] See also Figure 1-4 The utility model provides a four-bucket quantitative packaging scale, comprising a quantitative component 1 and a blanking component 2;

[0025] The quantitative component 1 includes a frame 101 and four weighing components 3. The inner wall of the frame 101 is fixed with a diversion cylinder 102 and four buffer buckets 103.

[0026] A protective seat 104 and a collecting hopper 105 are fixed to the inner wall of the diverter cylinder 102. A diverter motor 106 is fixed inside the protective seat 104. A diverter disk 107 is fixed to the drive shaft of the diverter motor 106. Four diverter tubes 108 are fixed to the bottom end of the diverter cylinder 102. The four diverter tubes 108 are evenly distributed in a ring shape. The diverter motor 106 drives the diverter disk 107 to rotate. The diverter disk 107 rotates at a high speed to drive the seeds at the top to perform centrifugal motion, so that the seeds are evenly distributed to the inlets of the four diverter tubes 108. The diverter tubes 108 guide the seeds to the top of the linear feeder 110. The collecting hopper 105 causes the seeds to gather at the top of the diverter disk 107.

[0027] The inner walls of the four buffer hoppers 103 are fixed with horizontal plates 109, and the tops of the four horizontal plates 109 are fixed with linear feeders 110. The linear feeders 110 push the seeds on the top to move slowly, causing the seeds to pass through the buffer hoppers 103 and fall into the interior of the material trough 305;

[0028] A collector box 111 is fixedly provided on the front of the frame 101, and a box door is hinged on the front of the collector box 111. A programmable controller is fixedly provided inside the collector box 111, and four electric valves 307, four weight sensors 303, four linear feeders 110, a shunt motor 106, two regulating motors 207 and two telescopic cylinders 203 are all electrically connected to the programmable controller. The target mass to be weighed is set through the programmable controller, and the programmable controller reads and records each weight sensor 303, and then selects the combination of material blocks 304 closest to the target mass through calculation, analysis, combination and screening, and then opens the electric valve 307 corresponding to the above combination of material blocks 304, and introduces the material trough 305 into the interior of the lower hopper 202 through the discharge pipe 306, so as to realize the quantitative feeding of seeds;

[0029] Specifically, first, the gathering hopper 105 causes the seeds to gather at the top of the diverter disk 107, and the diverter motor 106 drives the diverter disk 107 to rotate. The high-speed rotation of the diverter disk 107 drives the seeds at the top to perform centrifugal motion, so that the seeds are evenly distributed to the entrances of the four diverter tubes 108. The diverter tubes 108 guide the seeds to the top of the linear feeder 110. The linear feeder 110 will push the seeds at the top to move slowly, causing the seeds to pass through the buffer bucket 103 and fall into the interior of the material trough 305.

[0030] Example 2:

[0031] The blanking assembly 2 includes a shaped plate 201, which is fixedly arranged on the inner wall of the frame 101. A blanking hopper 202 is hingedly connected to the inner wall of the shaped plate 201. A telescopic cylinder 203 is hingedly connected between the blanking hopper 202 and the shaped plate 201 through a hinge seat. A movable hopper 204 is slidably connected to the surface of the blanking hopper 202. Dovetail grooves 205 and mounting grooves 206 are provided on both sides of the blanking hopper 202. An adjusting motor 207, a dovetail block 208 and a transmission screw 209 are provided on both sides of the blanking hopper 202.

[0032] Two adjustment motors 207 are fixedly mounted inside the two mounting slots 206 , and both adjustment motors 207 are forward and reverse motors. The two adjustment motors 207 drive the transmission screw 209 to rotate.

[0033] Two dovetail blocks 208 are slidably mounted on the inner walls of the two dovetail grooves 205. One side of the two dovetail blocks 208 is fixedly connected to the inner walls of both sides of the moving bucket 204. The dovetail blocks 208 guide and limit the moving bucket 204, thereby improving the stability of the moving bucket 204 during movement and preventing the moving bucket 204 from completely separating from the lower hopper 202.

[0034] Two transmission screws 209 are rotatably mounted on the inner walls of the two dovetail grooves 205 via sealed bearings. The contact portions of the two transmission screws 209 and the two dovetail blocks 208 are threadedly connected via screw nuts. One end of the two transmission screws 209 is fixedly connected to the transmission shafts of the two adjustment motors 207. The rotation of the transmission screws 209 drives the dovetail blocks 208 to slide along the dovetail grooves 205.

[0035] Specifically, the two telescopic cylinders 203 are started by the programmable controller, and the telescopic ends of the two telescopic cylinders 203 are shortened and drive the lower hopper 202 to rotate a certain angle, thereby lowering the height of the discharge port, which is convenient for feeding containers of different heights. Furthermore, the two adjusting motors 207 are started by the programmable controller, and the two adjusting motors 207 rotate and drive the two transmission screws 209 to rotate. The two transmission screws 209 will drive the moving bucket 204 to slide through the two dovetail blocks 208, causing the moving bucket 204 and the lower hopper 202 to slide relative to each other, thereby changing the horizontal position of the discharge port. There is no need to translate the frame 101 after the lower hopper 202 rotates, which is convenient for adapting to the packaging container conveyor belt in the quantitative packaging production line.

[0036] Example 3:

[0037] The four weighing assemblies 3 each include a support box 301, which is fixedly arranged on the inner wall of the frame 101. A through groove 302 is provided on the surface of the four support boxes 301. A weight sensor 303 is fixedly provided on the inner wall of the bottom end of the four support boxes 301. The top of the four weight sensors 303 is slidably connected to a material storage block 304 that slides with the inner wall of the support box 301. The top of the four material storage blocks 304 is provided with a material storage groove 305. The surface of the four material storage blocks 304 is fixedly provided with a discharge pipe 306 connected to the material storage groove 305. The surface of the four discharge pipes 306 is fixedly provided with an electric valve 307. The four discharge pipes 306 are arranged to be inclined downward.

[0038] Specifically, the weight sensor 303 will transmit the mass data of the seeds after they fall into the trough 305 to the programmable controller. The programmable controller will subtract the total mass data of the material block 304, the discharge pipe 306 and the electric valve 307 from the above mass data to obtain the seed mass data inside the trough 305. The target mass to be weighed is set through the programmable controller. The programmable controller will read and record the seed mass data obtained by the four weight sensors 303, and through calculation, analysis, combination and screening, select the combination of material blocks 304 closest to the target mass, and then open the electric valve 307, and introduce the material trough 305 into the interior of the lower hopper 202 through the discharge pipe 306 to realize quantitative feeding of seeds.

[0039] During use, the two telescopic cylinders 203 are started by the programmable controller, and the telescopic ends of the two telescopic cylinders 203 are shortened and drive the lower hopper 202 to rotate a certain angle, thereby lowering the height of the discharge port, which is convenient for feeding containers of different heights. Furthermore, the two adjusting motors 207 are started by the programmable controller, and the two adjusting motors 207 rotate and drive the two transmission screws 209 to rotate. The two transmission screws 209 will drive the moving bucket 204 to slide through the two dovetail blocks 208, causing the moving bucket 204 and the lower hopper 202 to slide relative to each other, thereby changing the position of the discharge port in the horizontal direction. There is no need to translate the frame 101 after the lower hopper 202 rotates, which is convenient for adapting to the packaging container conveyor belt in the quantitative packaging production line.

[0040] After adjusting the height and horizontal position of the discharge port, an appropriate amount of seeds are poured into the collecting hopper 105. The collecting hopper 105 causes the seeds to gather at the top of the diverter plate 107. The diverter motor 106 drives the diverter plate 107 to rotate. The diverter plate 107 rotates at high speed to drive the seeds at the top to perform centrifugal motion, so that the seeds are evenly distributed to the inlets of the four diverter pipes 108. The four diverter pipes 108 guide the seeds to the tops of the four linear feeders 110. The four linear feeders 110 push the seeds at the top to move slowly, causing the seeds to pass through the four buffer hoppers 103 and fall into the interior of the four material troughs 305.

[0041] The weight sensor 303 will transmit the mass data of the seeds after they fall into the trough 305 to the programmable controller. The programmable controller will subtract the total mass data of the material block 304, the discharge pipe 306 and the electric valve 307 from the above mass data to obtain the seed mass data inside the trough 305. The target mass to be weighed is set through the programmable controller. The programmable controller will read and record the seed mass data obtained by the four weight sensors 303, and through calculation, analysis, combination and screening, select the combination of material blocks 304 closest to the target mass, and then open the electric valve 307, and introduce the material trough 305 into the interior of the lower hopper 202 through the discharge pipe 306 to realize quantitative feeding of seeds.
