Description

Technical Field

[0001] The present application relates to the technical field of sample dividers, and in particular to a sample divider for evenly dividing materials. Background Art

[0002] Traditional grain sampling uses a simple physical method, which is to manually disperse and mix the grains and then pour them into a sampling bucket to obtain two samples. This operation method is not conducive to on-site sampling of large granaries and has the problem of low work efficiency. In order to solve the above problems, the existing technology uses multiple feed channels connected to the bottom of the silo, so that the material can enter the material tank through different feed channels. Compared with the above manual sampling method, its work efficiency is improved. However, since grains are generally mixed with other substances, when two or more different materials are unevenly mixed in the silo, it will cause the material that finally enters the material tank to be uneven, and the effect of uniform distribution of materials cannot be achieved. In addition, when the same sample is sampled, there will be problems of uneven sampling of appearance, quality, and quality. Utility Model Content

[0003] In order to solve the problem of uneven distribution of grain distribution devices proposed in the above background technology, the present application provides a sample divider that evenly distributes grains.

[0004] The present application provides a sample divider for evenly dividing materials, which adopts the following technical solution:

[0006] A receiving tray is provided with at least one material discharge channel, the top of the material discharge channel is connected to a material receiving area, and the center of the material receiving area coincides with the center of the receiving tray;

[0007] The unloading device is capable of rotating relative to the receiving tray and includes at least one unloading channel, the discharge port of which is located directly above the receiving area;

[0008] Among them, the material falling from the discharge channel can first enter the material receiving area, and evenly enter the discharge channel during the rotation of the receiving plate.

[0009] By adopting the above-mentioned technical solution, the material can be made to enter the receiving tray in a uniformly rotating state from the discharge channel at a constant flow rate and speed, that is, the material first passes through the discharge device, and then enters the receiving area at a constant flow rate and speed, and finally enters different discharge channels. Since the discharge channel rotates at a uniform speed along with the receiving tray, the probability of each discharge channel passing under the discharge channel is the same, so that the quality and quality of the materials entering different discharge channels tend to be the same, thereby avoiding uneven material distribution and improving the uniformity of material distribution.

[0010] Optionally, the number of the receiving tray is at least one. When the number of the receiving tray exceeds one, two adjacent receiving trays are coaxially arranged to rotate relative to each other.

[0011] By adopting the above technical solution, different numbers of receiving trays can be set according to actual needs. When the number of receiving trays is greater than one, multiple receiving trays are stacked and can rotate relative to each other, which can further improve the uniformity of material distribution and achieve better material distribution effects.

[0012] Optionally, also include:

[0013] The material tank is installed below the material discharge channel of the lowest receiving tray, and the inner cavity is connected to the material discharge channel.

[0015] Optionally, the blanking device further includes:

[0016] The hopper is configured to store materials. The discharge channel is connected to the lower end of the hopper and the inner cavity is connected to the inner cavity of the hopper, so that the material can fall from the hopper into the discharge channel under the action of its own gravity. A discharge module is installed at the end of the discharge channel, and the discharge channel is a tubular or trough-shaped structure.

[0017] By adopting the above technical solution, the material can be stored in the hopper, and then the material can be subjected to primary sampling through at least one discharge channel, which can increase the material sampling rate.

[0018] Optionally, multiple material discharge channels are evenly distributed around the center of the material tray.

[0019] By adopting the above technical solution, the time taken by different material discharge channels to pass under the same material discharge channel can be made to be similar, thereby making the quality of materials entering different material discharge channels tend to be the same.

[0020] Optionally, the discharge channel has an inverted cone structure that is wider at the top and narrower at the bottom.

[0021] By adopting the above technical solution, the diameter of the upper end of the discharge channel is enlarged to avoid the situation where materials accumulate above the receiving tray and cannot be discharged.

[0022] Optionally, a first ring and a second ring that are coaxial and have different diameters are fixed above the material receiving tray, and an annular material receiving area is formed between the first ring and the second ring.

[0023] By adopting the above technical solution, the material receiving area formed by the first ring and the second ring is mainly used to receive the material, which can play the role of blocking the material and prevent the material from falling outside the material receiving tray.

[0052] The present application is further described in detail below with reference to the accompanying drawings.

[0053] Example 1

[0054] like Figure 1-5 As shown, the embodiment of the present application discloses a sample divider for evenly dividing materials, comprising:

[0055] The receiving tray 7 is provided with at least one material discharge channel 701, and the top of the material discharge channel 701 is connected to the material receiving area 702. The center of the material receiving area 702 coincides with the center of the receiving tray 7. The material discharge channel 701 is an inverted cone structure that is wide at the top and narrow at the bottom. Specifically, in this example, a plurality of funnel-shaped small material discharge bins are evenly distributed around the central axis of the edge of the receiving tray 7. The internal channel of the small material discharge bin is the material discharge channel 701. A first ferrule 14 and a second ferrule 15 that are coaxial and have different diameters are fixed above the receiving tray 7. An annular material discharge area 702 is formed between the first ferrule 14 and the second ferrule 15 to achieve a material blocking effect.

[0056] A material discharge device capable of rotating relative to the receiving plate (7), comprising at least one material discharge channel 8, the discharge port of the material discharge channel 8 being located directly above the receiving area 702;

[0057] Among them, the material falling from the discharge channel 8 can first enter the receiving area 702, and evenly enter the discharge channel 701 during the rotation of the receiving tray 7; in actual scenarios, the receiving tray 7 can rotate relative to the discharge device, and the receiving tray 7 can be made into a rotatable structure, or the discharge device can be designed as a rotatable structure, or both can be designed as rotatable structures, and no specific limitation is made here.

[0058] Specifically, it also includes a material tank 4, which is installed below the discharge channel 701 of the lowest receiving tray 7, and the inner cavity is connected to the discharge channel 701, wherein the material tank 4 can be installed at the discharge port below the discharge channel 701 by means of a threaded connection.

[0059] Specifically, the blanking device further includes:

[0060] The hopper 9 is configured to store materials. The discharge channel 8 is connected to the lower end of the hopper 9 and the inner cavity is connected to the inner cavity of the hopper 9, so that the material can fall from the hopper 9 into the discharge channel 8 under the action of its own gravity. A discharge module is installed at the end of the discharge channel 8. The discharge channel 8 is tubular, wherein the discharge module mainly includes a motor, a soft dial and a shell. The motor drives the soft dial to rotate, and when the soft dial rotates, it drives the material to be discharged at a fixed rate. The structure and principle of this discharge module belong to the conventional technical means for controlling the discharge flow rate and flow rate in the prior art, and will not be elaborated here. In this example, there are three discharge channels 8. In addition, different numbers of discharge channels 8 can be set according to actual needs and the size of the actual sample divider. The configuration of the hopper 9 and the discharge channel 8 can realize the first-level material separation of the material, so that the material can smoothly enter the receiving area 702 on the receiving tray 7.

[0061] Specifically, multiple discharge channels 701 are evenly distributed around the center of the receiving tray 7. Such an arrangement allows the discharge channels 701 to rotate around the center of the receiving tray 7 during operation, so that different discharge channels 701 can pass through the discharge end of the discharge channel 8.

[0062] Specifically, it also includes:

[0063] Fixed frame 3;

[0064] The motor 5 is mounted inside the fixed frame 3 and has an adjustable speed. In this example, the motor 5 is a servo motor 5 , and the sample divider is controlled by a PLC controller. The speed of the motor 5 can be adjusted according to actual needs, thereby adjusting the rotation speed of the receiving tray 7.

[0065] A mounting flange 6 connected to the output shaft of the motor 5;

[0066] The receiving tray 7 is fixed on the mounting flange 6 and is coaxially connected to the mounting flange 6 .

[0067] Specifically, it also includes a box body 1, the unloading device is installed on the box body 1, and the receiving tray 7 is arranged in an internal position of the box body 1. More specifically, in this example, the lower end of the hopper 9 is fixed on the upper surface of the box body 1, and the unloading channel 8 is located inside the box body 1, so that without affecting the feeding of the hopper 9, the internal components are safely protected and the aesthetics is improved.

[0068] Specifically, it also includes a door panel 13, which can be opened and closed and installed on one side of the box body 1, and can be installed on the box body 1 using hinges;

[0069] It also includes a fixing plate 12, which is fixed at an upper position on one side of the box body 1, and an operation panel 10 and a control button 11 are installed on the surface. The operation panel 10 is a touch screen, which is electrically connected to the PLC controller and is used to input parameters, debug equipment, etc. The control button 11 can be a switch button.

[0070] Specifically, it also includes anti-slip pads 2, which are installed at the four corners below the fixing frame 3 and are made of rubber or silicone material, and are mainly used to achieve an anti-slip effect.

[0071] When this sampler for uniform material distribution is in use, grains or other materials are first stored in the hopper 9, and then enter the discharge channel 8 under the action of their own gravity, and fall into the receiving area 702 of the receiving tray 7 along the discharge channel 8. At this time, the receiving tray 7 rotates under the drive of the motor 5, so that the materials falling from the same discharge channel 8 fall into the different discharge channels 701 below in a constant amount, that is, the probability of each discharge channel 701 passing through the outlet of the discharge channel 8 is the same, and finally the mass and quality of the materials collected in the material tank 4 tend to be the same, which is conducive to improving the uniformity of material distribution; during operation, the speed of the motor 5 can also be controlled through the operation panel 10, and finally the rotation speed of the receiving tray 7 is controlled to meet different sampling requirements.

[0072] Example 2

[0073] like Figure 6 As shown, the only difference between this embodiment and the above-mentioned embodiment 1 is that the feed channel 8 is a trough-type structure. More specifically, the feed channel in this example is a V-shaped structure inclined downward, and a vibrator can be further provided below the feed channel 8. Compared with the tubular structure in embodiment 1, this structure has the advantages of simple structure, low production cost and good feed uniformity.

[0074] Example 3:

[0075] like Figure 7-8 As shown, the difference between this embodiment and the above embodiment 1 is that there are two receiving trays 7, and the two adjacent receiving trays 7 are coaxial and relatively rotatable, that is, the receiving trays 7 are stacked, and each receiving tray 7 can rotate independently. Figure 8 As shown, the motor 5 of the upper receiving tray 7 is located near the top of the fixing frame 3, with the output shaft facing downward and connected to the upper receiving tray 7. The motor 5 of the lower receiving tray 7 is consistent with the structure of the first embodiment. In this way, the two receiving trays can rotate independently in the same or opposite directions. Such an arrangement can further improve the uniformity of material distribution. In addition, in other embodiments, the number of receiving trays 7 can be designed to be more according to actual needs, which is not limited here.

[0076] 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.
