DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0026] like Figure 2-4 As shown, the sample dividing mechanism 2 includes a feed hopper 201, a feed pipe 202 is connected to the bottom of the feed hopper 201, a first fixed plate 203 is installed on one side of the feed pipe 202, a first electric telescopic rod 210 is installed on the first fixed plate 203, a first plug plate 212 is installed at the telescopic end of the first electric telescopic rod 210, and is used to insert or pull out the first plug plate 212, and first connecting plates 205 are installed on the three sides of the feed hopper 201, and the first connecting plate 205 is fixedly connected to the second connecting plates 206 installed on the three sides of the top of the four-branch pipe, and the connection between the four-branch pipe and the feed pipe 202 is realized by using the first connecting plate 205 and the second connecting plate 206, and the four-branch pipe is composed of two first connecting plates 205 and 206. The material discharging pipe 207 and two second material discharging pipes 208 are composed. A second fixed plate 204 is installed on the four-branch pipe. A second electric telescopic rod 209 is installed on the second fixed plate 204. A second plug plate 211 is installed at the telescopic end of the second electric telescopic rod 209. The second plug plate 211 is inserted or pulled out by the second electric telescopic rod 209 to realize material discharging or stop discharging. It can also realize two-point discharging and four-point discharging of materials. A cross partition frame 214 is installed inside the material delivery pipe 202. The cross partition frame 214 divides the material delivery pipe 202 into four cavities. The four cavities are respectively connected to the four material discharging pipe inlets 213 at the top of the four-branch pipe. An electric valve is installed on the discharge port 303.

[0027] like Figure 2-7 As shown, the angle between two adjacent first discharge pipes 207 or second discharge pipes 208 is less than 90 degrees. The two discharge pipes with an angle less than 90 degrees can discharge materials into one storage tank at the same time, or discharge materials into two storage tanks at the same time; the angle between the adjacent first discharge pipes 207 and the second discharge pipes 208 is greater than 90 degrees; the discharge pipes with an angle greater than 90 degrees discharge materials into two storage tanks at the same time;

[0028] like Figure 2-3As shown, the material storage mechanism 3 includes a material storage bin 301, and a material storage bin partition plate 302 is installed inside the material storage bin 301. The material storage bin partition plate 302 divides the material storage bin 301 into four material storage troughs of the same volume. Two inclined plates 304 are arranged at the bottom of the material storage troughs. The inclined plates 304 are connected to the material storage bin partition plate 302. The two inclined plates 304 are spliced ​​to form a lower material trough. The lower material trough is inclined, and the lowest end of the lower material trough is connected to the discharge port 303. Four discharge ports 303 are evenly arranged on the bottom of the peripheral side of the material storage bin 301, and the discharge port 303 is connected to the lower material trough, so that the material entering the material storage trough is conveniently transported to the discharge port 303 through the lower material trough and discharged through the discharge port 303.

[0029] like Figure 3 As shown, a stirring motor 306 is installed on the storage bin partition plate 302 near the center of the storage bin 301 in the storage trough, and a stirring rod 305 is connected to the main shaft of the stirring motor 306. A plurality of stirring rods are installed on the stirring rod 305. A slipping electric ring 215 is installed at the bottom of the quarter pipe through a connecting plate. The slipping electric ring 215 is electrically connected to the stirring motor 306. The stirring motor 306 can drive the stirring rod 305 to rotate, thereby driving the stirring rods on the stirring rod 305 to stir the material, thereby achieving the effect of stirring while dividing the material, and when the storage bin 301 rotates, the slipping electric ring 215 is used to prevent the connecting wires from being entangled.

[0030] like Figure 1 As shown, a feed port 6 is provided at the top of the outer frame 1, and the feed port 6 is connected to the feed hopper 201. The feed hopper 201 is installed on the top of the outer frame 1 by bolts, and the material enters the feed hopper 201 through the feed port 6. The discharge hopper 5 is installed on the outer frame 1 by bolts, and the feed port of the discharge hopper 5 is fitted with the peripheral side of the storage bin 301. When the discharge port 303 of the storage bin 301 is rotated to align with the discharge hopper 5, the electromagnetic valve is opened, and the material is discharged through the discharge hopper 5, and then the electromagnetic valve is closed for the next material distribution.

[0031] like Figure 4-5 As shown, the first connecting plate 205 is welded to the three sides of the feed hopper 201, and the second connecting plate 206 is welded to the three sides of the top of the four-branch pipe. The first connecting plate 205 and the second connecting plate 206 are fixedly connected by bolts, leaving a gap between the top of the four-branch pipe and the bottom of the conveying pipe 202 for the second plug plate 211 to be inserted.

[0032] like Figure 6As shown, the first plug plate 212 is installed on the telescopic end of the first electric telescopic rod 210 by bolts. The first plug plate 212 is inserted into the conveying pipe 202 through the first electric telescopic rod 210 to block the two cavities in the cross partition frame 214. The first plug plate 212 is used to block two of the four cavities, so that the material can be discharged through the other two cavities, thereby dividing the material into two equal parts.

[0033] like Figure 6 As shown, the second plug plate 211 is installed on the telescopic end of the second electric telescopic rod 209 by bolts. The second plug plate 211 is inserted into the gap between the top of the four-branch pipe and the bottom of the conveying pipe 202 through the second electric telescopic rod 209, and is used to block the four cavities in the cross dividing frame 214. The second plug plate 211 can be used to block the material from being discharged through the four-branch pipe. After the material fills the entire feed hopper 201, the second electric telescopic rod 209 is opened to pull the second plug plate 211 out from the top of the four-branch pipe, allowing the material in the conveying pipe 202 to enter the four discharge pipe inlets 213 through the four cavities, and then be discharged into the four storage troughs through the first discharge pipe 207 and the second discharge pipe 208, thereby realizing the four equal division of the material.

[0034] The distance between the discharge ports of the two first discharge pipes 207 or the second discharge pipes 208 is smaller than the width of the middle of the top of the storage trough in the storage bin 301, so that the two first discharge pipes 207 can discharge the material into one storage trough at the same time, and the two second discharge pipes 208 can discharge the material into one storage trough at the same time, thereby realizing two equal divisions of the material.

[0035] Working principle: A multifunctional fully automatic sample divider. When in use, the material enters the feed hopper 201 through the feed port 6 at the top of the outer frame 1;

[0036] When the material needs to be divided into two equal parts, the first method is: the servo motor 401 is controlled by the PLC control system to work, thereby driving the storage bin 301 to rotate, so that the two adjacent storage slots on the storage bin 301 are aligned with the two first discharge pipes 207, that is, the two first discharge pipes 207 are separated by the storage bin partition plate 302, so that the two first discharge pipes 207 are respectively aligned with one storage slot, and before loading and sampling, the first plug plate 212 is inserted into the conveying pipe 202 by the first electric telescopic rod 210 to block the two cavities on the cross dividing frame 214. After the loading is completed, the second plug plate 211 is driven by the second electric telescopic rod 209 to be pulled out of the conveying pipe 202, so that the two cavities on the cross dividing frame 214 are connected with the discharge pipe inlet 213 at the top of the two first discharge pipes 207, so that the material is transported to the storage slot through the two first discharge pipes 207, so as to realize the material being divided into two equal parts;

[0037] When the material needs to be divided into two equal parts, the second method is: the servo motor 401 drives the storage bin 301 to rotate, so that the two first discharge pipes 207 are aligned with one storage trough, and the two second discharge pipes 208 are aligned with one storage trough; before starting to feed, the first plug plate 212 does not need to be inserted into the feed pipe 202, so that the four cavities in the cross partition frame 214 are connected to the discharge pipe inlet 213 at the top of the four-branch pipe. When the material is divided, the second plug plate 211 is quickly pulled out by the second electric telescopic rod 209, so that the material is discharged into one storage trough through the two first discharge pipes 207, and the material is discharged into the other storage trough through the two second discharge pipes 208, completing the material division into two equal parts;

[0038] When the material needs to be unsorted, the two first discharge pipes 207 are aligned with one storage trough, and the two second discharge pipes 208 are aligned with one storage trough; before starting to feed, the first plug plate 212 needs to be inserted into the feed pipe 202, so that the two cavities in the cross partition frame 214 are connected with the two discharge pipe inlets 213 at the top of the four-branch pipe. When the material is divided, the second plug plate 211 is quickly pulled out by the second electric telescopic rod 209, so that the material is discharged into a storage trough through the two first discharge pipes 207, and the device realizes the unsorted operation;

[0039] When the material needs to be divided into four equal parts, the servo motor 401 drives the storage bin 301 to rotate, so that the two first discharge pipes 207 and the two second discharge pipes 208 are aligned with the corresponding storage slots, which is equivalent to the four discharge pipes aligning with the four storage slots. Before the material is fed, the first plug plate 212 does not need to be inserted into the feed pipe 202, so that the four cavities in the cross partition frame 214 are connected with the discharge pipe inlet 213 at the top of the four-dividing pipe. When the material is divided, the second plug plate 211 is driven to be quickly pulled out by the second electric telescopic rod 209, so that the material is evenly discharged into the four storage slots through the two first discharge pipes 207 and the two second discharge pipes 208, completing the material division into four equal parts;

[0040] When the equal distribution is completed, the feed port of the discharge hopper 5 is fitted with the peripheral side of the storage bin 301, and the storage bin 301 is rotated by the servo motor 401. When the discharge port 303 of the storage bin 301 is rotated to align with the discharge hopper 5, the solenoid valve is opened, and the material is discharged through the discharge hopper 5. After the material is discharged, the solenoid valve is closed, and the storage bin 301 is rotated again to rotate the discharge port 303 of another storage slot to align with the discharge hopper 5, and then the solenoid valve is opened for unloading, and the operation is performed in sequence to discharge the materials in multiple storage slots.

[0041] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
