Description

Technical Field

[0001] This utility model relates to the field of grain sampler technology, and in particular to a non-powered mixing and sampler. Background Technology

[0002] In the grain, oil, and feed industry, after grain, oil, and feed are stored and fixed in their current form, a sampler is needed for comprehensive sampling and mixing during new grain acceptance or old grain re-inspection. Grain samplers are commonly used sample processing equipment in grain or seed testing and analysis. Their main function is to mix and reduce the grain samples obtained during the sampling process, ultimately obtaining representative subsamples of a certain weight for subsequent testing. Generally, they are divided into two main categories: on-site grain receiving sampling and laboratory sampling, with on-site sampling being the preceding step to laboratory sampling. Traditional grain samplers in the grain industry are generally classified into three basic types: horizontal grid samplers, bell-shaped samplers, and rotary samplers. They mainly consist of a grain inlet hopper, a sampling device, and a subsample hopper. During sampling, the laboratory technician manually mixes the sample and loads it into the grain inlet hopper. The sample is then reduced into subsamples by the sampling device. Multiple proportions of subsamples are required, generally obtained using multi-stage or multiple sampling methods. The sampling process also helps to mix the sample to a certain extent.

[0003] Existing samplers mix grains using an electric motor inside the sampler, but this can damage the grains and greatly increase sampling errors. Furthermore, when dividing grains, different proportions are usually divided again after the sampler has taken the first sample, making it impossible to adjust the proportion of subsamples inside the sampler.

[0004] Therefore, we propose a non-powered mixing and dispensing device. Utility Model Content

[0005] The main purpose of this utility model is to provide a non-powered mixing and dispensing device, which can effectively solve the problems of existing dispensing devices that use a motor inside the device for electric mixing during the sampling process. However, the motor mixing process can damage the grain and greatly increase the sampling error. Secondly, when dispensing grain, it is mostly necessary to dispense different proportions after sampling with the dispensing device, and it is impossible to adjust the sampling ratio inside the dispensing device according to the sampling ratio.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A non-powered mixing and dispensing device includes a first support with an upper plate and a bottom plate, wherein a mixing and dispensing mechanism is provided in the upper plate of the first support.

[0008] The mixing and sampling mechanism includes a feeding tank, the lower end of which is connected to a mixing tank via a flange, the lower end of which is connected to a guide tank via a flange, the lower end of which is connected to a sampling tank via a flange, and the bottom of the sampling tank is provided with a return trough, the lower end of which is connected to a grain receiving pipe. The return trough is fixedly installed on the base plate of the first support, and the grain receiving pipe is located directly above the return trough.

[0009] The inner wall of the mixing tank is fixedly equipped with several inclined guide plates at equal intervals, and an installation rod is fixedly installed between the several guide plates. A first conical plate is fixedly installed at the upper end of the installation rod.

[0010] Furthermore, the upper plate of the first bracket has a mounting hole in the middle, and the mixing and dispensing mechanism is installed in the mounting hole of the upper plate of the first bracket.

[0011] Furthermore, a second bracket with an mounting plate is fixedly installed on the upper plate of the first bracket. The mounting plate of the second bracket has a through hole in the middle. A negative pressure suction tank is fixedly installed in the through hole. A top cover is provided on the top of the negative pressure suction tank. A suction pipe is connected to the top of the top cover. An air duct is connected to the side wall of the negative pressure suction tank. A discharge pipe is provided at the bottom of the negative pressure suction tank.

[0012] Furthermore, a discharge port is provided at the upper center of the discharge tank, and a connecting pipe is fixedly installed at the center of the discharge port. The upper part of the connecting pipe is connected to the discharge pipe, and the lower end of the connecting pipe is inserted into the discharge port. A cover is provided on one side of the lower end of the connecting pipe.

[0013] Furthermore, a conical trough is fixedly installed on the inner wall of the feed tank, and the conical trough is located directly below several of the guide plates.

[0014] Furthermore, the inner wall of the sample distribution tank is fixedly equipped with a plurality of support rods arranged in a circumferential array, and a sample distribution groove is fixedly installed between the plurality of support rods. The lower end of the sample distribution groove is connected to a sample distribution tube, which penetrates one side of the bottom of the sample distribution tank.

[0015] Furthermore, the inner wall of the sample distribution tank located above several of the support rods is fixedly equipped with eighteen equally divided side rods arranged in a circumferential array. A feeding trough is formed between two adjacent equally divided side rods, and the number of feeding troughs is also eighteen. Among them, three of the feeding troughs are provided with sample dispensing slots, and five feeding troughs are left empty between every two sample dispensing slots. The lower ends of the three sample dispensing slots are all located on the sample dispensing troughs, and the return sample trough is located directly below the fifteen feeding troughs.

[0016] Furthermore, an installation plate is fixedly installed at the middle position of each of the eighteen equally divided side rods. An insertion hole is provided in the middle of the installation plate, and a groove is provided on the installation plate. A bearing is placed in the groove, and a rod is inserted into the insertion hole. A second conical plate is fixedly installed at the upper end of the rod, and a circular plate is fixedly installed at the lower end of the second conical plate. A limiting plate is fixedly installed at the lower end of the circular plate, and the limiting plate is inserted into the inner ring of the bearing. Conical side plates are fixedly installed at each of the three equal divisions of the second conical plate, and three of the conical side plates are located directly above the three sample dispensing troughs. An adjusting rod is fixedly installed at one end of one of the conical side plates. An adjusting groove is provided on one side of the sample dispensing tank, and the adjusting rod passes through the adjusting groove.

[0017] Furthermore, a return pipe is connected to the bottom of the return grain tank.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model, through its sampling tank, enables non-powered mixing. Compared to the motor-driven mixing in the prior art, it effectively avoids damage to the grain during the mixing process. The grain falls through the discharge port onto the first conical plate and is guided to disperse in all directions. Then, under the action of the guide plate, the grain is mixed and then continues to be conveyed downward through the conical trough at the lower end. At the same time, the modular mixing and sampling mechanism allows for the selective addition of one or more sampling tanks, which better achieves the mixing of grain, avoids sampling errors, and increases the grain mixing effect.

[0020] 2. This utility model, through its sampling tank, allows for proportional sampling of grain. In this application, the grain sampling inlet is set to one-sixth of the tank. During sampling, the adjusting rod is moved to rotate the conical side plate located on the sampling trough away from the top of the trough. At this time, the grain falling above the second conical plate will disperse in all directions and be conveyed downwards through the three sampling troughs and fifteen feeding troughs. The grain passing through the three sampling troughs enters the sampling trough, and the grain passing through the fifteen feeding troughs enters the return sampling trough. This achieves the extraction of one-sixth of the grain sample. When sampling is not needed, the adjusting rod is rotated to block the top of the sampling trough, and all the grain will fall from the fifteen feeding troughs and enter the return sampling trough. This is more convenient and faster than existing methods that cannot accurately control the sampling ratio.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1-6 As shown, the non-powered mixing and dispensing device includes a first support 1 with an upper plate and a bottom plate, and a mixing and dispensing mechanism is provided in the upper plate of the first support 1.

[0031] The mixing and sampling mechanism includes a feeding tank 6, a mixing tank 7 connected to the lower end of the feeding tank 6 via a flange, a guide tank 8 connected to the lower end of the mixing tank 7 via a flange, a sampling tank 9 connected to the lower end of the guide tank 8 via a flange, a return trough 23 provided at the bottom of the internal part of the sampling tank 9, a grain receiving pipe 16 connected to the lower end of the return trough 23, and a return trough 10 fixedly installed on the base plate of the first support 1, with the grain receiving pipe 16 located directly above the return trough 10.

[0032] In this embodiment, the mixing and sampling mechanism includes a discharge tank 6, a mixing tank 7, a guide tank 8, and a sampling tank 9. The discharge tank 6, mixing tank 7, guide tank 8, and sampling tank 9 are arranged vertically and adjacent to each other and connected by flanges. Different numbers of mixing tanks 7 can be installed and used according to the degree of mixing uniformity. That is, two or more mixing tanks 7 can be used in the entire mixing and sampling mechanism to achieve different degrees of mixing. Compared with the existing mixing by installing a motor to rotate, this can avoid damage to the grain and reduce sampling and testing errors. On the other hand, it can greatly reduce production costs and subsequent electricity costs.

[0033] Several inclined guide plates 19 are fixedly installed at equal intervals on the inner wall of the mixing tank 7. An installation rod 17 is fixedly installed in the middle of the several guide plates 19. A first conical plate 18 is fixedly installed at the upper end of the installation rod 17.

[0034] The grain falls onto the first conical plate 18 and is dispersed in all directions by the guiding action, and then is mixed by the action of the guide plate 19.

[0035] In one specific embodiment, a mounting hole is provided in the middle of the upper plate of the first support 1, and the mixing and dispensing mechanism is disposed in the mounting hole of the upper plate of the first support 1.

[0036] In one specific embodiment, a second bracket 2 with an mounting plate is fixedly installed on the upper plate of the first bracket 1. The mounting plate of the second bracket 2 has a through hole in the middle, and a negative pressure suction tank 3 is fixedly installed in the through hole. A top cover is provided on the top of the negative pressure suction tank 3, and a suction pipe 4 is connected to the top of the top cover. An air duct 5 is connected to the side wall of the negative pressure suction tank 3, and a discharge pipe is provided at the bottom of the negative pressure suction tank 3.

[0037] In one specific embodiment, a discharge port 13 is provided at the upper middle position of the discharge tank 6. A connecting pipe is fixedly installed at the middle position of the discharge port 13. The upper part of the connecting pipe is connected to the discharge pipe, and the lower end of the connecting pipe is inserted into the discharge port 13. A cover 12 is provided on one side of the lower end of the connecting pipe. The opening and closing of the cover 12 is affected by the external negative pressure adsorption and the weight of the grain at the upper end. The opening angle of the cover 12 is not vertically downward, so that the cover 12 can be closed when subjected to negative pressure adsorption.

[0038] In one specific embodiment, a conical trough 20 is fixedly installed on the inner wall of the feed tank 8, and the conical trough 20 is located directly below a plurality of guide plates 19.

[0039] In one specific embodiment, a plurality of support rods 30 in a circumferential array are fixedly installed on the inner wall of the sample tank 9, and a sample trough 22 is fixedly installed between the plurality of support rods 30. The lower end of the sample trough 22 is connected to a sample tube 15, which penetrates one side of the bottom of the sample tank 9.

[0040] In one specific embodiment, the inner wall of the sample tank 9 located above several support rods 30 is fixedly installed with eighteen equally divided side rods 28 in a circumferential array. A feeding trough is formed between two adjacent equally divided side rods 28, and the number of feeding troughs is also eighteen. Among them, three feeding troughs are provided with sample leakage troughs 29, and five feeding troughs are left empty between every two sample leakage troughs 29. The lower ends of the three sample leakage troughs 29 are all located on the sample tank 22, and the return trough 23 is located at the lower end of the fifteen feeding troughs.

[0041] In one specific embodiment, an installation plate is fixedly installed at the middle position of the eighteen equally divided side rods 28. An insertion hole 27 is opened at the middle position of the installation plate. A groove is opened on the installation plate, and a bearing 31 is set in the groove. An insertion rod 25 is inserted into the insertion hole 27. A second conical plate 21 is fixedly installed at the upper end of the insertion rod 25. A circular plate is fixedly installed at the lower end of the second conical plate 21. A limiting plate 26 is fixedly installed at the lower end of the circular plate, and the limiting plate 26 is inserted into the inner ring of the bearing 31. Conical side plates 24 are fixedly installed at each of the three equal divisions of the second conical plate 21, and three of the conical side plates 24 are located directly above the three sample troughs 29. An adjusting rod 14 is fixedly installed at one end of one of the conical side plates 24. An adjusting groove is opened on one side of the sample trough 9, and the adjusting rod 14 is inserted through the adjusting groove.

[0042] It should be noted that the adjusting rod 14, the second conical plate 21, and the conical side plate 24 are an integral structure. Moving the adjusting rod 14 can realize the overall rotation of the second conical plate 21, which drives the three conical side plates 24 to rotate, thereby realizing the overall opening and closing of the three sample troughs 29. Grain enters the sample trough 22 after passing through the three sample troughs 29, and enters the sample trough 23 after passing through the fifteen feeding troughs.

[0043] Specifically, the length of the adjusting trough is large enough to avoid the influence of the conical side plate 24 between the sampling trough 29 and the feeding trough when the grain falls. Therefore, when moving the adjusting rod 14, the adjusting rod 14 can be moved to a position away from the sampling trough 29 to avoid the grain not being sampled proportionally during the falling process.

[0044] In one specific embodiment, the bottom of the grain return tank 10 is connected to a grain return pipe 11.

[0045] The grain return pipe 11 is used to connect with the external grain return pipe. The power for subsequent grain output relies on the external source. This utility model does not involve this part, as it belongs to the prior art and will not be described in detail here.

[0046] When the mixing and sampling mechanism is installed in the mounting hole on the upper plate of the first bracket 1, the flange used to connect the discharge tank 6 and the mixing tank 7 is snapped onto the top of the mounting hole.

[0047] It should be noted that this utility model is a non-powered mixing and dispensing device. When using it, first, place the device on one side of the sampler, connect the extraction pipe 4 to the grain output pipe of the sampler rod, and connect the air pipe 5 to the external negative pressure suction device. Under the action of negative pressure adsorption, the grain enters the negative pressure suction tank 3 from the extraction pipe 4. During the negative pressure grain suction process, the cover 12 below the discharge port 13 will block the connecting pipe. When the negative pressure adsorption stops, the grain will fall downwards due to gravity. At this time, the cover 12 opens, and the grain enters the mixing and dispensing mechanism from the discharge port 13. The grain falls from the discharge port 13 to the first conical plate 18 and is dispersed in all directions by the guiding action. Then, the grain is mixed under the action of the guide plate 19, and then continues to be conveyed downwards through the conical trough 20 set at the lower end. At this time, the grain falls onto the second conical plate 21. Before this, the adjusting rod 14 needs to be adjusted.

[0048] The adjustment rod 14 is moved to rotate the conical side plate 24 located on the sampling trough 29 away from the sampling trough 29. At this time, the grain falling above the second conical plate 21 will be dispersed in all directions and conveyed downward from the three sampling troughs 29 and the fifteen feeding troughs. The grain passing through the three sampling troughs 29 enters the sampling trough 22, and the grain passing through the fifteen feeding troughs enters the return trough. At this time, one-sixth of the grain sampling operation is achieved. When sampling is not needed, the adjustment rod 14 is rotated to block the top of the sampling trough 29, and all the grain will fall from the fifteen feeding troughs and enter the return trough. Compared with the existing method, which cannot accurately control the sampling ratio, it is more convenient and faster.

[0049] The grain entering the sampling tank 22 is the grain sample required by the device. It is obtained through the sampling pipe 15. The grain entering the tank 23 enters the grain return tank 10 through the grain receiving pipe 16. By connecting the external grain return pipe to the grain return pipe 11, the unwanted grain can be returned to the vehicle or grain depot, which is quite practical.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
