The conveying bin 13 is provided with an inlet 14 and an outlet 15 at two ends respectively, the inlet 14 and the outlet 15 are vertically arranged and are both in communication with the conveying cavity 131, the inlet 14 and the outlet 15 are both in a funnel structure, facilitating feeding and discharging. The conveying cavity 131 is horizontally provided with a conveying mechanism 16, the conveying mechanism 16 specifically comprises a first motor 161 and a conveying auger 162, the conveying auger 162 is rotatably connected with the conveying bin 13 at two ends respectively, the output end of the first motor 161 is in transmission connection with one end of the conveying auger 162, and a partition plate is further fixedly welded in the conveying cavity 131 to divide the cavity 131 into left and right two chambers, and the first motor 161 is arranged in the left chamber, so as to avoid that the material falls on the first motor 161 and affects or damages the first motor 161. Through the conveying mechanism 16, the white granulated sugar material can fall into the right chamber of the conveying cavity 131 from the inlet 14, be conveyed to the outlet 15 by the conveying auger 162, and fall out from the outlet 15.

[0024] The sampling device 2 specifically comprises a chute 21, a sampling pipe 22, a plurality of sampling cups 23, a cup supporting mechanism 24 and a cup separating mechanism 25. The sampling pipe 22 is obliquely arranged outside the outlet 15, the inlet end of the sampling pipe 22 is fixedly connected and communicated with the outlet 15, and the inlet end of the sampling pipe 22 is fixedly installed with an electric on-off valve 221, which is used for controlling the conduction or cut-off of the sampling pipe 22.

[0026] The cup supporting mechanism 24 specifically comprises a supporting plate 241, an extension piece 242, a pressure load sensor 243 and a spring 244. The extension piece 242 is fixedly installed on the upper end face of the base 11, and the pressure load sensor 243 is fixedly installed on the movable end of the extension piece 242 and is used to feed back the weight signal of the collected material in the sampling cup 23. In addition, the lower end face of the supporting plate 241 is movably connected with the movable end of the extension piece 242 through the spring 244.

When the extension piece 242 is in a maximum stroke state, the upper end face of the supporting plate 241 is flush with the groove bottom of the sampling section 212, so as to ensure the smooth sliding of the sampling cup 23. When the extension piece 242 is in a retracted state, the height of the supporting plate 241 is lower than the height of the placement hole 2121, so as to form a groove structure for limiting the placement of the sampling cup 23. A plurality of sampling cups 23 can be detachably placed in the cup storage section 211 of the sliding groove 21 and can slide from the head to the tail of the sliding groove 21. When one of the sampling cups 23 slides to the placement hole 2121, it is used to collect the material falling from the sampling pipe 22. The sampling pipe 22 is in an L-shaped tubular structure, and the placement hole 2121 is coaxially arranged with the outlet end of the sampling pipe 22, so that the white granulated sugar material can accurately fall into the sampling cup 23.

[0027] The cup separating mechanism 25 is arranged at the tail end of the cup storage section 211 and is used to separate the plurality of sampling cups 23 one by one. The cup separating mechanism 25 specifically comprises a special-shaped rod 251, a cam 252, a transmission rod 253 and a second motor 254. The special-shaped rod 251 is as shown in Figure 5 The special-shaped rod 251 specifically comprises a movable rod 2511, an upper blocking strip 2512 and a lower blocking strip 2513. The upper blocking strip 2512 and the lower blocking strip 2513 are specifically in a triangular columnar structure. The movable rod 2511 is rotatably connected to one side of the sliding groove 21. The cam 252 is fixedly sleeved on the transmission rod 253 and is arranged below the special-shaped rod 251. One end of the transmission rod 253 is rotatably connected to one side of the sliding groove 21, and the other end of the transmission rod 253 is in transmission connection with the output end of the second motor 254. The second motor 254 drives the cam 252 to rotate. The groove bottom of the sliding groove 21 is provided with a through hole 2111 (not shown in the figure, which is specifically two symmetrical triangular hole structures) for the movement of the lower blocking strip 2513. When the cam 252 rotates and abuts against the upper side of the special-shaped rod 251, the upper blocking strip 2512 of the special-shaped rod 251 is lifted, the lower blocking strip 2513 of the special-shaped rod 251 passes through the through hole 2111 and is lifted, the first sampling cup 23 closest to the cup separating mechanism 25 is separated, and the first sampling cup 23 slides down along the sliding groove 21. The lower blocking strip 2513 of the special-shaped rod 251 blocks the second sampling cup 23 adjacent thereto to prevent the second sampling cup 23 from sliding down.

[0028] It should be noted that the aforementioned conveying screw 162, electric switch valve 221, telescopic member 242, pressure load cell 243 and second motor 254 are all electrically connected with the PLC controller.

[0029] The working principle of the utility model is as follows: in the non-working state, the telescopic member 242 is completely retracted, the supporting plate 241 is below the placing hole 2121, and a groove structure is formed between the two; during sampling, the PLC controller is started, the PLC controller controls the cup distributing mechanism 25 to release a sampling cup 23, the sampling cup 23 falls onto the supporting plate 241 when sliding to the placing hole 2121, at this time, the spring 244 is compressed, the lower end surface of the supporting plate 241 just abuts against the pressure load cell 243, the PLC controller is controlled to open the electric switch valve 221, and the material falling from the discharge port 15 falls into the sampling cup 23 from the sampling pipe 22; when the weight value fed back by the pressure load cell 243 reaches the set maximum threshold value, the electric switch valve is closed, the telescopic member 242 drives the supporting plate 241 to move upwards, the supporting plate 241 is flush with the groove bottom of the sliding groove 21, the sampling cup 23 returns to the sliding groove 21 and slides downwards along the sliding groove until the sampling cup 23 is taken by the worker at the cup taking section of the sliding groove 21, the telescopic member 242 is retracted, and the sampling device enters the waiting working state.

[0030] The sampling device can set two sampling modes of timed sampling and quantitative sampling: the timed sampling is to set the sampling time, for example, to set 1-2 hours to release a sampling cup 23 for sampling, until the set sampling time is reached or the feedback signal of the pressure load cell 243 is not received and the sampling work is stopped, and the control unit sends a sampling completion signal to the external terminal; the quantitative sampling is to take a batch of white granulated sugar material as a sampling period, the control unit randomly controls the sampling device 2 to be opened until the control unit calculates and processes the feedback signal of the sampling cup 23, and the sampling is stopped when the sampling reaches a certain weight value.
