Abstract
Description
Technical Field
[0001] This application relates to the field of sample divider technology, and in particular to a novel sample divider. Background Technology
[0002] Currently, when sampling agricultural crops or grain products, it is generally necessary to mix multiple grains first and then pour the mixture into a unified container. Traditional grain sampling uses a simple physical method, where the grains are manually dispersed and mixed before being poured into the container to obtain two samples. This method is not suitable for on-site sampling in large grain warehouses and suffers from low work efficiency. Existing technologies also use machines for rapid grain sampling, but in actual operation, due to the inhomogeneity of mixing multiple grains, the final product in the container also suffers from inhomogeneity, resulting in inconsistent product quality. Furthermore, even when sampling the same type of grain, problems such as unevenness in appearance, quality, and grade can occur. Utility Model Content
[0003] To address the problem of uneven distribution during grain distribution in the aforementioned background technology, this application provides a novel sampler.
[0004] The novel sample divider provided in this application adopts the following technical solution:
[0005] A novel sample divider includes:
[0006] The turntable has a vertically oriented central axis and can rotate around the central axis. Materials can fall onto the surface of the turntable and drop down from the edge of the turntable.
[0007] The feeder is coaxially positioned below the turntable and can rotate relative to the turntable. It has a feeding channel inside, and the material falling from the turntable can fall into the feeding channel.
[0008] The material tank is installed at the lower end of the distributor, and its inner cavity is connected to the material discharge channel.
[0009] By adopting the above technical solution, the material falls onto the surface of the rotating turntable first, and then moves to the edge of the turntable under the action of centrifugal force, and finally falls into the distributor and tank below. In other words, the centrifugal method realizes the rapid dispersion and feeding of materials, increases the feeding speed, and also makes the material more evenly distributed on the surface of the turntable, so that the amount of material falling into the feeding channel is consistent and improves the uniformity of the sample.
[0010] Optionally, the number of the feeder is one.
[0011] By adopting the above technical solution, it is suitable for situations where multiple grains are mixed relatively evenly. A single distributor can achieve a uniform sample distribution effect, which can save equipment investment costs, time and electricity.
[0012] Optionally, the number of the distributors is two or more, and the two or more distributors are stacked vertically. Adjacent distributors can rotate relative to each other, and a discharge chute is provided between adjacent distributors. The discharge chute is configured to guide the material in the discharge channel of the upper distributor into the discharge channel of the lower distributor. The material tank is installed at the lower end of the lowermost distributor.
[0013] By adopting the above technical solution, after the initial sampling is carried out by the turntable, multiple relatively rotating distributors are used to further distribute the material evenly, making the sampling effect more uniform.
[0014] Optionally, the number of feeding channels on the distributor is one or more, and the one or more feeding channels are evenly distributed around the center of the distributor.
[0015] By adopting the above technical solution, different numbers of material feeding channels can be set according to the actual situation to meet the material distribution needs in different scenarios.
[0016] Optional, also includes:
[0017] A frame on which the turntable is rotatably mounted;
[0018] The hopper is fixed to the upper part of the frame and located above the turntable.
[0019] By adopting the above technical solution, the frame serves as the basic mounting component of the sampler, which is used to achieve stable installation of various parts. The hopper is used to store materials and discharge them under its own gravity.
[0020] Optionally, the turntable is a conical structure with a central upward convexity.
[0021] By adopting the above technical solution, the material can be easily moved along the surface of the conical structure towards the edge, thereby increasing the feeding speed.
[0022] Optionally, the upper surface of the turntable is provided with one or more guide blades, and the one or more guide blades are evenly distributed around the center of the turntable.
[0023] By adopting the above technical solution, the material is driven to move towards the edge of the turntable while rotating, avoiding the problem of the material sliding or rolling with the turntable for a long time in the circumferential direction. One or more guide blades are specifically set according to different working conditions and different turntable sizes to meet the usage needs of different scenarios.
[0024] Optionally, the feeder includes an outer ring and an inner ring, which are coaxially arranged. The feeding channels are evenly distributed within the annular area formed by the outer ring and the inner ring. A partition plate is provided between two adjacent feeding channels, and the upper surface of the partition plate is lower than the surfaces of the outer ring and the inner ring.
[0025] By adopting the above technical solution, the material can fall into the annular area formed by the outer ring and the inner ring during the process of falling into the distributor from above, and then fall into each feeding channel, thereby avoiding the material from splashing outwards during the falling process.
[0026] Optionally, the upper surface of the inner ring is lower than the upper surface of the outer ring.
[0027] By adopting the above technical solution, the outer ring, being higher than the inner wall of the inner ring, serves to block materials.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] The design of this utility model is quite simple. The material is first stored in the hopper. Under its own gravity, the material enters the turntable below. When the turntable rotates, the material moves towards the edge of the turntable under the action of centrifugal force and falls into the distributor below. This makes it easy for the material to enter different feeding channels and tanks at a constant flow rate and speed, so as to achieve the purpose of uniform material distribution.

[0038] The present application is further described in detail below with reference to the accompanying drawings.
[0039] like Figure 1-6 As shown in the embodiment of this application, a novel sample divider is disclosed, comprising:
[0040] Rack 1;
[0041] Turntable 3 is rotatably mounted on frame 1. Its central axis is set vertically and can rotate around the central axis. Material can fall on the surface of turntable 3 and fall down from the edge of turntable 3. Specifically, a first motor 4 is installed in the middle of frame 1. The output shaft of the first motor 4 is set upward and the shaft end is connected to turntable 3. After the first motor 4 is started, turntable 3 can rotate.
[0042] The feeder is coaxially positioned below the turntable 3 and can rotate relative to the turntable 3. It has a feeding channel 13 inside, and the material falling from the turntable 3 can fall into the feeding channel 13.
[0043] In one embodiment, the number of feeding channels 13 on the distributor is one;
[0044] In another embodiment, the number of feeding channels 13 on the distributor is more than one, and the more than one feeding channels 13 are evenly distributed around the center of the distributor.
[0045] Material tank 9 is installed at the lower end of the distributor and its inner cavity is connected to the material discharge channel 13. It is used to store the material after it has been finally sampled.
[0046] The hopper 2 is fixed on the upper end of the frame 1 and located above the turntable 3. A valve is installed at the discharge port of the hopper 2, which can be opened or closed according to the actual situation.
[0047] In one embodiment, the number of feeders is one.
[0048] In another embodiment, the number of distributors is two or more, and the two or more distributors are stacked vertically. Adjacent distributors can rotate relative to each other, and a discharge chute 6 is provided between adjacent distributors. The discharge chute 6 is configured to guide the material in the discharge channel 13 of the upper distributor into the discharge channel 13 of the lower distributor. The material tank 9 is installed at the lower end of the lowermost distributor. In this example, as... Figure 1-3As shown, there are two distributors: a first distributor 5 at the top and a second distributor 7 at the bottom. The first distributor 5 is fixedly installed on the frame 1. A discharge trough 6 is provided below the discharge channel 13 of the first distributor 5. The number of discharge troughs 6 is the same as the number of discharge channels 13 of the first distributor 5 and they correspond one-to-one. Multiple discharge troughs 6 are inclined downward and fixed together at the top. The cross-section of the discharge trough 6 is V-shaped, but it can also be a trough or other structures. The second distributor 7 is located below the discharge trough 6. The second distributor 7 is driven by a second motor 8 installed on the frame 1, which enables the second distributor 7 to rotate. The material tank 9 is installed at the lower end of the second distributor 7.
[0049] Specifically, the turntable 3 is a conical structure with a central upward convexity;
[0050] In one embodiment, a guide blade 301 is provided on the upper surface of the turntable 3;
[0051] In another embodiment, the upper surface of the turntable 3 is provided with one or more guide blades 301, and the one or more guide blades 301 are evenly distributed around the center of the turntable; the specific number of guide blades 301 can be adjusted according to the actual situation, and is not limited here;
[0052] In this example, there are four guide blades 301. The guide blades 301 have an arc-shaped structure. The conical structure of the turntable 3 and the arc-shaped guide blades 301 on the surface can improve the material feeding speed and the uniformity of material falling.
[0053] Specifically, the feeder includes an outer ring 11 and an inner ring 10, which are coaxially arranged. The feeding channels 13 are evenly distributed within the annular area formed by the outer ring 11 and the inner ring 10. A partition plate 12 is provided between two adjacent feeding channels 13. The upper surface of the partition plate 12 is lower than the surfaces of the outer ring 11 and the inner ring 10. More specifically, the upper surface of the inner ring 10 is lower than the upper surface of the outer ring 11.
[0054] When using this new type of sampler, grains or other mixed materials are first stored in the hopper 2. When discharging, the valve (or gate) in the middle of the hopper 2 is opened, and the material can fall to the center of the turntable 3 below under its own gravity. The turntable 3 rotates under the drive of the first motor 4, and the material can move along the surface of the turntable 3 to the edge under the action of centrifugal force, and then fall into the discharge channel 13 of the first distributor 5. The material falling from the discharge channel 13 of the first distributor 5 falls into the discharge trough 6, and then falls into the rotating second distributor 7 below. At this time, the material is sampled a second time, and finally falls from the discharge channel 13 of the second distributor 7 into the material tank 9 below, completing the sampling process. In this scheme, since the turntable 3 rotates relative to the first distributor 5 and the second distributor 7 rotates relative to the first distributor 5, the weight and quality of the material collected in the final material tank 9 are made to be similar, which is beneficial to the uniformity of material distribution. In addition, the first motor 4 and the second motor 8 can both be servo motors, and their speed can be controlled by a PLC controller. Different sample distribution requirements can be met by controlling the speed of the turntable 3 and the second distributor 7, which has the advantage of wide applicability.
[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
