Description

Technical Field

[0001] This utility model relates to the field of grain sampling technology, specifically to a grain sampling and separation device and separator. Background Technology

[0002] Grain sampling refers to the process of extracting representative samples from bulk grains according to certain standards and methods during grain storage and circulation for quality inspection. The purpose of sampling is to ensure that the test results accurately reflect the overall quality of the grain, thereby providing a basis for grain security management.

[0003] In the prior art, Chinese patent document CN117619714A discloses an automated grain quality testing system, which includes an intelligent sampling unit, a grain screening unit, and a vacuum suction hopper connected to the intelligent sampling unit via a three-way pipe. Part of the grain flowing in from the inlet of the three-way pipe flows into the intelligent sampling unit for sampling, while the other part flows into the grain screening unit for screening. In this scheme, the three-way pipe, i.e., the sampling and separation device, uses a valve to allow the grain to fall and flow separately. This method of separation makes it difficult to control the amount of grain falling, and cannot achieve precise quantitative separation of grain samples. Utility Model Content

[0004] The purpose of this utility model is to provide a grain sampling and separation device and separator, which solves the problem that in the existing sampling and separation device, the grain is divided by opening a valve to make the grain fall. This method of dividing the grain is difficult to control the amount of grain falling and cannot achieve accurate quantitative division of grain samples.

[0032] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0033] Reference Figures 1-2This embodiment provides a grain sampling and separation device, including a separating hopper 110, a diversion device 120, a quantitative hopper, and an installation platform 150, wherein the separating hopper 110, the diversion device 120, and the quantitative hopper are all installed on the installation platform 150. The separating hopper 110 is used to receive and store grain samples. The diversion device 120 is located at the outlet of the separating hopper 110. The diversion device 120 includes two diversion ports located at different positions. In the entire sampling process, multiple devices are typically used. The different positions of the diversion ports allow for the arrangement of multiple devices in different locations, achieving a reasonable spatial layout. The diversion device 120 carries the grain sample and slowly moves it to the diversion port for outflow. By controlling the movement speed of the grain, the movement speed is slow enough to ensure that the amount of grain flowing out of the diversion port is sufficiently small, thereby improving the diversion accuracy. The quantitative hopper is positioned corresponding to each diversion port to quantitatively receive the grain sample flowing out of the diversion port. The quantitative hopper monitors the amount of grain sample diverted to ensure that the diverting device 120 stops diverting when the specified amount is reached.

[0034] It is understandable that more than two diversion ports can be set according to the needs of the equipment, but only two are set in this embodiment.

[0035] As a preferred embodiment of the diversion device 120, such as Figure 1 and Figure 2 As shown, the diversion device 120 includes a conveyor belt 121 and a conveyor motor 123. The conveyor motor 123 is connected to the conveyor belt 121 and drives the conveyor belt 121 to convey in the forward or reverse direction. The diversion ports are located at both ends of the conveying direction of the conveyor belt 121. The rotational speed of the conveyor motor 123 is controllable, so the conveying speed of the conveyor belt 121 is also controllable. When the grain is about to reach the diversion port of the conveyor belt 121, the conveying speed of the conveyor belt 121 can be significantly slowed down, so that the grain flows out slowly from the diversion port, and less grain flows out per unit time, thereby improving the grain diversion accuracy.

[0036] Furthermore, side baffles 122 are provided on both sides of the conveyor belt 121 in the width direction, and the side baffles 122 are set higher than the conveying plane of the conveyor belt 121. The side baffles 122 and the conveying plane of the conveyor belt 121 together form a conveying space to accommodate the grain sample, which can prevent the grain sample from spilling during the conveying process. The length of the side baffles 122 is not less than the length of the conveying plane of the conveyor belt 121, ensuring that the grain is protected from spillage throughout the entire process of conveying to the diversion port.

[0037] In some embodiments, a mass sensor is installed between the metering hopper and the mounting platform 150 to monitor the weight of the grain in the metering hopper. By quantifying the grain sample by weight, even grain samples with different particle sizes can be quantified by weight without changing the hopper.

[0038] Specifically, each quantitative hopper is connected to the installation platform 150 via two support arms 151, and a mass sensor is installed between the support arm 151 and the supporting surface of the quantitative hopper. The two support arms 151 have two sets of mass sensors, which can simultaneously monitor the weight of the grain in the quantitative hopper, reducing monitoring errors. More than two sets of support arms 151 and mass sensors can be installed as needed.

[0039] It should be noted that both the conveyor belt 121 and the side baffle 122 are mounted on the installation platform 150. The metering hopper has a notch on its side facing the end of the conveyor belt 121, through which the ends of both the conveyor belt 121 and the side baffle 122 extend into the metering hopper. Grain samples fall onto the end of the conveyor belt 121, ensuring accurate placement of the sample into the metering hopper, reducing sample loss, and improving the metering accuracy of the hopper. Furthermore, compared to a design where the metering hopper is located below the conveyor belt 121, this reduces dropping errors and also makes the separation device more compact in terms of space.

[0040] Understandably, in some embodiments, a discharge assembly 160 is provided at the discharge port of the quantitative hopper, which opens or closes the discharge port of the quantitative hopper. The discharge assembly 160 controls the retention and release of grain samples in the quantitative hopper. Before the grain sample reaches a specified weight, the discharge assembly 160 closes the discharge port; after the grain sample reaches the specified weight, the discharge assembly 160 opens the discharge port to release the grain sample according to the instruction.

[0041] In some embodiments, a material switch is installed in the separating hopper 110. Two sets of material switches are provided, located at the bottommost and near the topmost positions inside the separating hopper 110, respectively. The material switches are used to detect the amount of grain sample in the separating hopper 110. The material switch at the bottom of the separating hopper 110 detects whether there is a grain sample in the separating hopper 110, while the material switch at an appropriate position above the separating hopper 110 monitors whether the sample in the separating hopper 110 has reached the required amount. The material switches can be photoelectric switches as used in the prior art, and specific details will not be elaborated further.

[0042] Another aspect of this utility model provides a grain sampling separator, such as... Figure 3As shown, the system includes a frame 200, a packaging device 300, a purification device 400, and the aforementioned separation device. The separation device diverts the grain sample into the packaging device 300 and the purification device 400. The packaging device 300 and the purification device 400 are located on different sides of the frame 200. The packaging device 300 is typically used for sealing and preserving the grain sample for subsequent verification and testing. For ease of access, the sealed sample is usually packaged on the outside of the frame 200. The purification device 400, used to remove impurities from the grain sample, generates vibration and noise. To minimize interference from these vibrations and noise, it is typically placed on the inside of the frame 200.

[0043] Specifically, the separation device is located at the top of the frame 200, and the input ends of the packaging device 300 and the impurity removal device 400 are respectively connected to the first quantitative hopper 130 and the second quantitative hopper 140 at different positions. Correspondingly, a first mass sensor 131 is installed between the first quantitative hopper 130 and the support arm 151, and a second mass sensor 141 is installed between the second quantitative hopper 140 and the support arm 151, for controlling precise quantitative dispensing.

[0044] It is understood that the separator adopts the aforementioned separation device and therefore possesses all the technical effects of the aforementioned separation device, which will not be elaborated upon here. The packaging device 300 and the impurity removal device 400 are not the main improvements of this application, and their specific structures will not be described in detail here.
