[0041] In a specific embodiment of the present invention, an image acquisition mechanism 21 is further included; the image acquisition mechanism 21 is installed at the outlet of the pipeline 20 and is located above the sieve plate 7, and is used to acquire an image of the sieve plate 7 and transmit it to the control system, and the control system judges whether the sieve holes on the sieve plate 7 are all filled with grains; when the sieve holes on the sieve plate 7 are all filled with grains, the control system controls the vibrating mechanism to stop vibrating, controls the lifting mechanism to rise, so as to generate a gap between the material taking plate 10 and the sieve plate 7, so as to facilitate the extraction of the material taking plate 10. Preferably, the image acquisition mechanism 21 is an industrial camera; the image acquisition mechanism 21 is installed directly above the sieve plate 7.

[0042] In a specific embodiment of the present invention, the control system includes a control panel 4 and a plc controller;

[0043] The control panel 4 is arranged on the outer wall of the housing of the feeding mechanism 1, and the control panel 4 is connected to the plc controller;

[0044] The plc controller is respectively connected to the switching mechanism, the lifting mechanism, the vibrating mechanism, the infrared counter 19, the image acquisition mechanism 21 and the control panel 4;

[0045] The control panel 4 is at least used to preset the number of grains;

[0046] The infrared counter 19 sends the detected grain quantity signal to the plc controller. The plc controller compares the grain quantity detected by the infrared counter 19 with a preset value. When the grain quantity detected by the infrared counter 19 reaches the preset value, the plc controller controls the switch mechanism to close the bin outlet;

[0047] The image acquisition mechanism 21 acquires the image of the sieve plate 7 and transmits it to the plc controller. The plc controller preprocesses the image and determines whether the sieve holes on the sieve plate 7 are all filled with grains.

[0048] As Figure 3 、 4 and shown in Figure 5, in a specific embodiment of the present invention, the switch mechanism includes a switch piece 17. The switch piece 17 is located at the bin outlet. The switch piece 17 is connected to the output shaft of the rotary motor 18. The rotary motor 18 controls the rotation of the switch piece 17 to control the opening and closing of the bin outlet.

The electric lock 8 is connected to the control system; the sieve plate 7 and the box body 12 are detachably connected; for different grains, sieve plates 7 with different sieve hole diameters can be designed for replacement; the connection through the electric lock can effectively suppress the displacement caused by vibration, while ensuring the convenience of replacing the sieve plate 7, and can flexibly adapt to a variety of application scenarios. The material taking plate 10 is connected to the box body 12 through a buckle 9 to restrict its movement during oscillation; the material taking plate 10 is installed in the box body 12 through a chute 30. One end of the material taking plate 10 is provided with a second handle 11, which is convenient for pulling it out of the box body after sampling.

[0050] In a specific embodiment of the present invention,

[0051] Four replaceable sieve plates 7 with different sieve hole diameters are designed, which are applicable to various grain types; the sieve hole layout of the sieve plate 7 is 4*4, and the sieve hole diameters of the replaceable sieve plates 7 are 3.5 mm, 4.0 mm, 4.5 mm, and 12.0 mm respectively; there is a 4*4 depression matrix on the material taking plate 10, corresponding to the sieve hole layout of the sieve plate 7. By designing sieve plates 7 with different sieve hole numbers and the corresponding material taking plates 10 with the corresponding number of depressions, the grain counting during sampling can be achieved, meeting the requirement of taking a certain number of grains each time. When the material taking plate 10 is installed in the box body 12, the descent of the sieve plate 7 is controlled by the lifting mechanism, so that the material taking plate 10 is in close fit with the sieve plate 7, which is beneficial to the accurate falling of the grains in correspondence. When replacing the sieve plate, the elevator 23 can be controlled to descend through the control screen 4, and the flexible connection bellows 13 is compressed synchronously, separating the box body 12 from the feeding mechanism 1, facilitating the removal of the feeding mechanism 1 for replacing the sieve plate 7.

[0052] In a specific embodiment of the present invention, the pipeline 20 is in an inclined Z shape, which disperses the falling of the grains and reduces the speed, contributing to accurate counting. And the discharge end of the pipeline 20 is located directly above the sieve plate 7, further improving the counting accuracy and facilitating the inspection of the position of the grains on the sieve plate.

[0053] As Figure 2 and 9 shown, in a specific embodiment of the present invention, the vibration mechanism includes a square box 16 and a vibration motor 24;

[0054] Inside the square box 16, there is a mounting plate 27. On the upper section of the mounting plate 27, there is a spring seat 29. At the upper end of the spring seat 29, a plurality of spring guide columns 26 are installed. The spring guide columns 26 are sleeved with springs 28. At the upper end of the spring guide columns 26, there is a vibration motor mounting plate 25, and a vibration motor 24 is installed at the center of the vibration motor mounting plate 25. One end of the lifting mechanism is connected to the bottom of the sieve plate 7, and the other end is connected to the square box 16.

[0055] In a specific embodiment of the present invention, the lifting mechanism includes an elevator 23; on both sides inside the box body 12, there are elevators 23, and a flexible connection bellows 13 is provided at the lower end of the box body 12 to adapt to the deformation during the lifting process.

[0056] In a specific embodiment of the present invention, it further includes a bracket 6; the upper end of the bracket 6 is connected to the feeding mechanism 1 through an inclined rod 5; the lower end of the bracket 6 is provided with casters 14, which improves the flexibility of the device.

[0057] In a specific embodiment of the present invention, preferably, a feed bin cover 2 is provided at the upper end of the feeding mechanism 1, and a first handle 3 is provided at the upper end of the feed bin cover 2, which is convenient for opening and closing and can effectively reduce the dust from falling in.

[0058] Working principle: During the use of the present invention, first select a sieve plate 7 with an appropriate aperture, install it on the box body 12 through an electric buckle 8, and move the feeding mechanism 1 directly above the sieve plate 7. Then, pour an appropriate amount of grain into the feeding mechanism 1, set parameters through the control panel 4, and start the electrically connected elevator 23 to lower the sieve plate 7 until it is in close contact with the material taking plate 10. When sampling, the control system controls the rotation motor 18 to drive the switch piece 17 to rotate slightly, so that a small amount of grain drops. The grain drops along the inclined Z-shaped pipe 20 and is dispersed with a reduced speed. The infrared counter 19 sends the detected grain quantity signal to the plc controller. The plc controller compares the grain quantity detected by the infrared counter 19 with the preset value. When the grain quantity detected by the infrared counter 19 reaches the preset value, the plc controller controls the switch mechanism to close the silo outlet; the grain passes through the infrared counter 19 and then is dispersed through the pipe 20 and slowly drops onto the sieve plate 7. When the grain drops onto the sieve plate 7 through the pipe 20, the image acquisition mechanism 21 at the discharge end of the pipe 20 acquires the image of the sieve plate 7 and transmits it to the plc controller. The plc controller preprocesses the image and judges whether the sieve holes on the sieve plate 7 are all filled with grain; when the sieve holes on the sieve plate 7 are all filled with grain, the plc controller sends an instruction to control the vibration mechanism to stop vibrating, controls the lifting mechanism to rise, so that a gap is generated between the material taking plate 10 and the sieve plate 7, facilitating the extraction of the material taking plate 10.

[0059] Preferably, after the plc controller performs image preprocessing, grayscaling, and denoising on the image data of the image acquisition mechanism 21, it converts the preprocessed image into a numerical matrix, processes the obtained numerical matrix according to the built-in algorithm in the judgment result to output the position and quantity of the grain in the sieve holes in the image, and judges whether the sieve holes on the sieve plate 7 are all filled with grain. When the sieve holes on the sieve plate 7 are not all filled with grain, the plc controller sends an instruction to control the rotation motor 18 to drive the rotation of the switch piece 17, opens the silo outlet again, so that a small amount of grain drops. When the sieve holes on the sieve plate 7 are all filled with grain, the plc controller sends an instruction to control the vibration mechanism to stop vibrating, controls the lifting mechanism to rise, so that a gap is generated between the material taking plate 10 and the sieve plate 7, facilitating the extraction of the material taking plate 10; loosen the buckle 9, and extract the material taking plate 10 through the second handle 11 to complete the sampling.

[0060] Preferably, the built-in algorithm of the plc controller is to establish a convolutional neural network CNN through the TensorFlow framework; the convolutional neural network CNN takes the preprocessed image as input, extracts the position and quantity characteristics of the grains in the sieve holes of the image, and compares the characteristics with the picture in which all the sieve holes on the preset sieve plate 7 are filled with grains, and outputs the result of whether all the sieve holes on the sieve plate 7 are filled with grains. The plc controller sends instructions according to the judgment result, with a high degree of automation and simple operation. The present invention is applicable to the sampling of various grains, and can be arranged relatively regularly during discharging, which is convenient for subsequent scanning, simplifies the operation process and improves the efficiency.

[0061] Image recognition can also be realized through template matching technology. Templates for different grain types are created according to the conventional outer contours and sieve hole positions of several common grains, and the region of interest ROI (i.e., the sieve hole position region) is fixed through the templates; when scanning the sieve plate image, through the template matching algorithm, quickly locate and identify one by one whether there are grains at each sieve hole position; when it is judged that there are grains in all, extract the shape features and texture features of the ROI for further confirmation, and then when the shape features and texture features of the ROI are within a certain threshold range, it can be determined that there are grains in this region.

[0062] It should be understood that although this specification is described according to each embodiment, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0063] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present invention, and they are not used to limit the protection scope of the present invention.
