Description

Technical Field

[0001] This utility model relates to a sample divider, and more particularly to a multi-proportion sample divider. Background Technology

[0002] Currently, the testing of the physicochemical properties of raw and auxiliary materials in industries such as steel and metallurgy requires the use of various samples. These samples need to be divided into samples of different weight proportions, resulting in a huge workload for sample division. The early manual sample division method is obviously inadequate for the needs. However, most existing sample division equipment divides the raw material into several equal portions according to the weight of the raw material, or extracts a small portion of the raw material based on its weight, discarding the majority of the remaining material. According to the performance testing requirements of the samples, it is often necessary to divide the raw material into samples of various weight proportions, and the divided samples need to be preserved in various multiple proportions. This device aims to accurately divide samples into multiple proportions by weight. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-proportion sampler with a reasonable structure, uniform feeding, multiple weight ratios for sample division, and accurate sample weight.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution. A multi-proportion sampler includes a frame, a feed hopper, a weighing hopper, a feeder base, a weighing module, a vibrating feeder, a sampler, 1-8 discharge pipes, 1-8 receiving boxes, a waste bin, and a control system. The feed hopper is located at the top of the frame, the weighing module is located in the upper part of the frame, the weighing hopper is suspended on the weighing module and located below the feed hopper, the feeder base is located below the weighing hopper, the vibrating feeder is located inside the feeder base with its outlet located above the sampler, the 1-8 discharge pipes are respectively located on the outer wall of the sampler, the 1-8 receiving boxes are placed inside the frame and are respectively located below the 1-8 discharge pipes, and the waste bin is placed inside the frame and located below the waste outlet of the sampler. The weighing module, the vibrating feeder, and the sampler are respectively connected to the control system.

[0005] The multi-ratio sampler includes a motor, a belt drive pair, a housing, and a sample distribution tube. The motor and housing are fixed on the frame. The driving end of the belt drive pair is located on the motor, and its driven end is located on the sample distribution tube. The sample distribution tube is located inside the housing. The motor is connected to the control system.

[0006] The multi-proportion sampler has a cone-shaped housing with three discharge ports on its outer circumference: a triple discharge port, a double discharge port, and a single discharge port. The triple discharge pipe, the double discharge pipe, and the single discharge pipe are fixed to the housing. The lower part of the housing is equipped with a triple receiving box, a double receiving box, and a single receiving box.

[0007] Compared with the prior art, this utility model has the following advantages: (i) because it adopts the feeding method of vibrating feeder, the material flow is uniform, which is conducive to more accurate sampling by the sampler; (ii) because it adopts the type of weighing module hoisting hopper and vibrating feeder, the feeding weight is controllable and accurate, and the sampling of multiple ratio weights is more accurate; (iii) because it adopts the discharge port of multiple ratios distributed around the circumference of the sampler, the discharge is smoother, more uniform and stable.

[0011] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0012] like Figure 1 , Figure 2 and Figure 3As shown, the multi-proportion sampler includes a frame 1, a feed hopper 2, a weighing hopper 3, a feeder base 4, a weighing module 5, a vibrating feeder 6, a sampler 7, three discharge pipes (a triple discharge pipe 12, a double discharge pipe 13, and a single discharge pipe 14), three receiving boxes (a triple receiving box 15, a double receiving box 16, and a single receiving box 17), a waste bin 18, and a control system. The feed hopper 2 is located at the top of the frame 1, the weighing module 5 is located in the upper part of the frame 1, the weighing hopper 3 is suspended on the weighing module 5 and located below the feed hopper 2, and the feeder base 4 is located below the weighing hopper 3. The vibrating feeder 6 is located inside the feeder base 4, with its outlet above the sampler 7. Three discharge pipes, namely the triple discharge pipe 12, the double discharge pipe 13, and the single discharge pipe 14, are respectively located on the outer wall of the sampler 7. Three receiving boxes, namely the triple receiving box 15, the double receiving box 16, and the single receiving box 17, are placed inside the frame 1 and are located below the three discharge pipes, namely the triple discharge pipe 12, the double discharge pipe 13, and the single discharge pipe 14. The waste box 18 is placed inside the frame 1 and is located below the waste outlet of the sampler 7. The weighing module 5, the vibrating feeder 6, and the sampler 7 are respectively connected to the control system. The sample dispenser 7 includes a motor 8, a belt drive pair 9, a housing 10, and a sample dispensing tube 11. The motor 8 and the housing 10 are fixed on the frame 1. The driving end of the belt drive pair 9 is located on the motor 8, and its driven end is located on the sample dispensing tube 11. The sample dispensing tube 11 is located inside the housing 10. The motor 8 is connected to the control system. The housing 10 of the sample dispenser 7 has a conical structure. Three discharge ports are provided on the circumference of its outer wall, namely a triple discharge port, a double discharge port, and a single discharge port. Triple discharge tubes 12, double discharge tubes 13, and single discharge tubes 14 are fixed thereon, respectively. Triple receiving boxes 15, double receiving boxes 16, and single receiving boxes 17 are correspondingly provided at the bottom.

[0013] The multi-proportion sampler operates as follows: After the material is fed into the feed hopper 2, it enters the weighing hopper 3. According to the program instructions, the vibrating feeder 6 and the sampler 7 are started. The vibrating feeder 6 feeds the material evenly. The material entering the distribution pipe 11 of the sampler 7 is fed at a uniform speed along the inner wall of the box 10 of the sampler 7. The material enters the triple discharge port, double discharge port and single discharge port on the circumference of the box 10 respectively, and is discharged through the triple discharge pipe 12, double discharge pipe 13 and single discharge pipe 14 respectively. The output material falls into the triple receiving box 15, double receiving box 16 and single receiving box 17 respectively. The material that is not sampled during the feeding process of the distribution pipe 11 is discharged through the waste outlet at the bottom of the box 10 and falls into the waste box 18. The weighing module 5 stops feeding after reducing a certain weight.
