Description

Technical Field

[0001] This invention relates to the field of grain testing, and more particularly to a single-grain grain analyzer. Background Technology

[0002] In order to obtain parameters such as size, weight, hardness, and moisture content of grains during grain testing, it is necessary to take samples of the grains. The size, weight, hardness, and moisture content of the samples indirectly reflect the overall size, weight, hardness, and moisture content of the grains.

[0003] The number of grains in a sample is often quite large. Current technology generally uses manual testing, whereby inspectors use various testing instruments to test the size, weight, hardness, and moisture content of each grain in the sample. This results in multiple data points for each parameter. By averaging these multiple data points for each parameter, the value of that parameter in the sample grain can be obtained, and the value of that parameter in the sample grain can indirectly reflect the value of that parameter in the whole grain.

[0004] However, such operations are relatively cumbersome and labor-intensive for testing personnel. Furthermore, manual testing may introduce human error, and the accuracy of various parameters cannot be guaranteed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a single grain analyzer to solve the above-mentioned problem.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A single grain analyzer includes: a weight detection mechanism, a hardness and moisture detection mechanism, a size detection mechanism, a feeding mechanism, a discharging mechanism, and a transfer mechanism; the feeding mechanism is disposed above the weight detection mechanism, the transfer mechanism is disposed between the weight detection mechanism and the hardness and moisture detection mechanism, the size detection mechanism is disposed close to the transfer mechanism, and the discharging mechanism is disposed below the hardness and moisture detection mechanism; the weight detection mechanism, the hardness and moisture detection mechanism, the size detection mechanism, the feeding mechanism, the discharging mechanism, and the transfer mechanism are all fixedly installed on the equipment frame.

[0007] The beneficial effects of this invention are as follows: the weight detection mechanism facilitates the detection of the weight of each grain entering from the feeding mechanism, and the grain after weight detection is transported to the transfer mechanism; the size detection mechanism detects the size (length, width, height) of the grain; the hardness and moisture detection mechanism facilitates the detection of hardness and moisture of the grain after size detection; and the discharge mechanism facilitates the collection of the grain after detection. This invention facilitates the automated detection of the size, weight, hardness, and moisture of grain, reduces the labor intensity of detection personnel, avoids the introduction of human error, and thus improves the accuracy of detection results.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the sliding block is provided with a downwardly inclined sliding groove, which is conducive to the individual grains of grain that are removed from the weighing device sliding down onto the horizontally set photographing platform, thereby facilitating the size detection mechanism to perform size detection on the individual grains of grain.

[0017] Furthermore, the hardness and moisture detection mechanism includes: a second driving device, a third driving device, a moisture detection electrode plate, and a receiving plate. The second driving device, the third driving device, and the receiving plate are all fixedly installed on the equipment frame. The other end of the imaging platform is flush with and fixedly connected to the top of the receiving plate. The second driving device is installed on the receiving plate. The output end of the third driving device is fixedly connected to one end of the moisture detection electrode plate, which drives the other end of the moisture detection electrode plate to move closer to or away from the second driving device.

[0019] Furthermore, the second driving device includes: a second servo motor, a second transmission box, and a feeding wheel. The second transmission box is fixedly installed on the equipment frame.

Multiple toothed structures for feeding grain are spaced apart and fixedly installed on the circumferential sidewall of the feeding wheel.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the second transmission box is conducive to transmitting the power output by the second servo motor to the output shaft of the second transmission box, and then to the feeding wheel through the output shaft of the second transmission box, driving the feeding wheel to rotate above the receiving plate, thereby moving the single grain on the imaging platform to be opposite to the moisture detection electrode plate.

[0021] Furthermore, the size detection mechanism includes a first camera and a second camera, both of which are fixedly mounted on the equipment frame. The first camera is positioned above the imaging platform, and the second camera is positioned on the side of the imaging platform.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the first camera and the second camera are advantageous for taking pictures above and to the side of a single grain of grain, respectively, thereby obtaining the size of the single grain of grain.

[0023] Furthermore, the feeding mechanism includes a feeding hopper and a vibratory feeder. Both the feeding hopper and the vibratory feeder are fixedly installed on the equipment frame.

[0029] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] like Figures 1 to 7As shown, this embodiment provides a single grain analyzer, including: a weight detection mechanism 1, a hardness and moisture detection mechanism 2, a size detection mechanism 3, a feeding mechanism 4, a discharging mechanism 5, and a transfer mechanism 6; the feeding mechanism 4 is disposed above the weight detection mechanism 1, the transfer mechanism 6 is disposed between the weight detection mechanism 1 and the hardness and moisture detection mechanism 2, the size detection mechanism 3 is disposed close to the transfer mechanism 6, and the discharging mechanism 5 is disposed below the hardness and moisture detection mechanism 2. The weight detection mechanism 1, the hardness and moisture detection mechanism 2, the size detection mechanism 3, the feeding mechanism 4, the discharging mechanism 5, and the transfer mechanism 6 are all fixedly mounted on the equipment frame 7.

[0031] It should be noted that in this embodiment, the weighing device 11, the first servo motor 121 and the material presence sensor 142 in the weight detection mechanism 1, the second servo motor 211, the third servo motor 221 and the moisture detection electrode plate 23 in the hardness and moisture detection mechanism 2, the first camera 31 and the second camera 32 in the size detection mechanism 3, and the vibratory feeder 42 in the feeding mechanism 4 are all electrically connected to the controller to perform signal transmission, control and calculation analysis. The transmission, control and calculation analysis of these signals are all existing technologies. like Figure 1 and Figure 2 As shown, the equipment frame 7 includes: a housing 71, a first mounting plate 72, a second mounting plate 73, and a plurality of support feet 74. The first mounting plate 72 and the second mounting plate 73 are spaced apart and fixedly installed inside the housing 71, and the plurality of support feet 74 are spaced apart and fixedly installed on the bottom outer wall of the housing 71.

[0032] The beneficial effects of this embodiment are as follows: the weight detection mechanism facilitates the detection of the weight of each grain entering from the feeding mechanism, and the grain after weight detection is transported to the transfer mechanism; the size detection mechanism detects the size (length, width, height) of the grain; the hardness and moisture detection mechanism facilitates the detection of hardness and moisture of the grain after size detection; and the discharge mechanism facilitates the collection of the grain after detection. This invention facilitates the automated detection of the size, weight, hardness, and moisture of grain, reduces the labor intensity of detection personnel, avoids the introduction of human error, and thus improves the accuracy of the detection results.

[0033] Preferred, such as Figure 3 and Figure 4As shown, the weight detection mechanism 1 includes: a weighing device 11, a first driving device 12, a toggle member 13, and a detection member 14; the weighing device 11, the first driving device 12, and the detection member 14 are all fixedly installed on the equipment frame 7. The first driving device 12 is fixedly connected to one end of the toggle member 13 and is used to drive the other end of the toggle member 13 to rotate. The transfer mechanism 6, the weighing device 11, the toggle member 13, the detection member 14, and the feeding mechanism 4 are arranged sequentially from bottom to top at intervals.

[0034] It should be noted that, in this embodiment, as Figure 2 and Figure 4 As shown, the weighing device 11 is fixedly installed on the top of the weighing device support platform 111, and the weighing device support platform 111 is fixedly installed on the first mounting plate 72.

[0035] The advantages of adopting the above preferred scheme are: the weighing device is conducive to weighing individual grains of grain entering from the feeding mechanism, thereby obtaining the weight of individual grains of grain; the first driving device is conducive to driving the actuating component to rotate above the weighing device, thereby limiting the individual grains of grain to be weighed on the weighing device during the process, or after the weighing is completed, the individual grains of grain on the weighing device are transferred to the transfer mechanism; the detection component is conducive to generating a signal to the controller after detecting the fall of individual grains of grain, thereby stopping the operation of the feeding mechanism, and thus ensuring that there is only one grain of grain on the weighing device.

[0036] Preferred, such as Figures 3 to 5 As shown, the first driving device 12 includes a first servo motor 121 and a first transmission box 122. The first transmission box 122 is fixedly installed on the device frame 7. Its input end is connected to the output shaft of the first servo motor 121, and its output end is vertically connected to the output shaft 123 of the first transmission box. The actuating component 13 includes a first connecting rod 131 and a material feeding cylinder 132. The material feeding cylinder 132 is a tube. One end of the first connecting rod 131 is fixedly connected to the side wall of the material feeding cylinder 132, and the other end is fixedly connected to the output shaft 123 of the transmission box. The material feeding cylinder 132 is located above the weighing device 11.

[0037] It should be noted that in this embodiment, the first transmission box 122 is fixedly installed on the first mounting plate 72, and the first servo motor 121 can be directly fixedly installed on the box body of the first transmission box 122, or fixedly installed on the first mounting plate 72. The first transmission box 122 is existing technology. It is equipped with gears and other structures for transmission, which are used to transmit the power generated by the first servo motor 121 to the output shaft 123 of the first transmission box, and then to the toggle member 13 through the output shaft 123 of the first transmission box. Driven by the first driving device 12, the feeding cylinder 132 is rotated to be directly above the weighing device 11, thereby receiving the single grain falling from the feeding mechanism 4 and guiding the single grain onto the weighing device 11 for weighing. During this process, there is a gap between the bottom end of the feeding cylinder 132 and the top end of the weighing device 11, thereby avoiding inaccurate detection data caused by the weighing device 11 contacting the feeding cylinder 132. At the same time, this gap is smaller than the thickness of the single grain, so that after weighing, the single grain can be pushed out from the weighing device 11 to the transfer mechanism 6 by rotating the feeding cylinder 132. The feeding cylinder 132 is a tube with an inner diameter larger than the single grain to be tested. This facilitates moving the single grain to the center of the weighing device 11 by several back-and-forth swings of the feeding cylinder 132. However, it should be noted that this embodiment is only suitable for grains with non-circular outlines that are not easy to roll, such as rice, wheat, and corn. This avoids the single grain rolling and contacting the feeding cylinder 132 due to the back-and-forth swings of the feeding cylinder 132, thereby ensuring the accuracy of weight detection. During the rotation of the feeding cylinder 132, no matter how the feeding cylinder 132 rotates (rotates to be directly above the weighing device 11, rotates to push a single grain of grain from the weighing device 11 into the transfer mechanism 6, or swings back and forth to push a single grain of grain to the middle of the weighing device 11), it is always above the weighing device 11.

[0038] The advantages of adopting the above preferred solution are: the first transmission box is conducive to transmitting the power generated by the first servo motor to the output shaft of the first transmission box, and then to the feeding cylinder through the output shaft of the first transmission box and the first connecting rod, driving the feeding cylinder to rotate above the weighing device, thereby realizing the weighing of a single grain and the feeding out after weighing.

[0039] Preferred, such as Figure 3 and Figure 4 As shown, the detection component 14 includes a mounting plate 141 and a material presence / absence sensor 142. The mounting plate 141 is fixedly mounted on the equipment frame 7, and the material presence / absence sensor 142 is fixedly mounted on the bottom surface of the mounting plate 141. The mounting plate 141 is provided with a material discharge hole 143, which is a through hole and is located above the weighing device 11.

[0040] It should be noted that in this embodiment, the mounting horizontal plate 141 is horizontally arranged, with one end fixedly mounted on the top of the mounting vertical plate 144, and the bottom end of the mounting vertical plate 144 fixedly mounted on the first mounting plate 72. When the material presence sensor 142 is fixedly installed on the bottom surface of the mounting plate 141, it is not within the range of the material drop hole 143, thereby avoiding interference with the falling grain. The material presence sensor 142 is a through-beam light sensor, which is existing technology. When it detects a falling grain, it will generate a corresponding signal. The discharge hole 143 is coaxially positioned directly above the weighing device 11.

[0041] The beneficial effect of adopting the above preferred solution is that the material sensor generates a signal after detecting a falling grain, thereby stopping the feeding mechanism and preventing the next grain from entering the weight detection mechanism.

[0042] Preferred, such as Figures 2 to 4 As shown, the transfer mechanism 6 includes a sliding block 61 and a photographing platform 62. The sliding block 61 is provided with a downwardly inclined sliding groove. The top of the sliding groove is located below the weighing device 11, and its bottom end is fixedly connected to one end of the photographing platform 62. The photographing platform 62 is horizontally set, and its other end is fixedly connected to the hardness and moisture detection mechanism 2.

[0043] The advantages of adopting the above preferred solution are: the sliding block is provided with a downwardly inclined sliding groove, which is conducive to the individual grains of grain that are removed from the weighing device sliding down onto the horizontally set photographing platform, thereby facilitating the size detection mechanism to detect the size of individual grains of grain.

[0044] Preferred, such as Figure 6 and Figure 7 As shown, the hardness and moisture detection mechanism 2 includes: a second driving device 21, a third driving device 22, a moisture detection electrode plate 23, and a receiving plate 24. The second driving device 21, the third driving device 22, and the receiving plate 24 are all fixedly installed on the equipment frame 7. The other end of the imaging platform 62 is flush with and fixedly connected to the top of the receiving plate 24. The second driving device 21 is installed on the receiving plate 24. The output end of the third driving device 22 is fixedly connected to one end of the moisture detection electrode plate 23, which is used to drive the other end of the moisture detection electrode plate 23 to move closer to or away from the second driving device 21. The moisture detection electrode plates 23 are spaced above the receiving plate 24. A pressure sensor for detecting grain hardness is provided inside the third driving device 22. The discharge mechanism 5 is located below the receiving plate 24.

[0045] It should be noted that: Figure 6 and Figure 7 As shown, in this embodiment, the third driving device 22 includes: a third servo motor 221, a lead screw 222, a fixed block 223, a slider 224, and a second connecting rod 225. The third servo motor 221 and the fixed block 223 are spaced apart and fixedly mounted on the first mounting plate 72. The output shaft of the third servo motor 221 is connected to one end of the lead screw 222 via a coupling. The other end of the lead screw 222 is rotatably connected to the fixed block 223 via a bearing. The slider 224 is threaded onto the lead screw 222. Two second connecting rods 225 are symmetrically arranged on both sides of the lead screw 222 and pass through the fixed block 223. The two ends of the second connecting rods 225 are respectively connected to the slider 224 and the moisture detection electrode plate 225. 3. Fixed connection: The third servo motor 221 drives the lead screw 222 to rotate, causing the slider 224 to move along the length of the lead screw 222. This causes the moisture detection electrode plate 23 to move synchronously through the second connecting rod 225, thereby causing the moisture detection electrode plate 23 to move closer to or further away from the feeding wheel 213 in the second driving device 21. The moisture detection electrode plate 23 moves closer to the feeding wheel 213 until the moisture detection electrode plate 23 and the feeding wheel 213 squeeze a single grain. During this process, the pressure sensor installed in the third driving device 22 is useful for detecting the pressure value when the grain breaks, thereby characterizing the hardness of the grain. When the moisture detection electrode plate 23 contacts the grain, it can detect the moisture of the grain. The pressure sensor is installed inside the slider 224 and connected to one end of the second connecting rod 225. In other preferred embodiments (not illustrated), the third driving device 22 is a cylinder, which is fixedly mounted on the first mounting plate 72. Its output shaft is fixedly connected to one end of the moisture detection electrode plate 23. The other end of the moisture detection electrode plate 23 is driven to move closer to or away from the feed wheel 213 in the second driving device 21 by pushing out or retracting the output shaft. In other preferred embodiments, the pressure sensor is set at the connection between the output shaft of the cylinder and the moisture detection electrode plate 23. The hardness detection principle and the moisture detection principle are the same as described above, and will not be repeated here. The receiving plate 24 is fixedly installed on the first mounting plate 72; The gap between the moisture detection electrode plate 23 and the receiving plate 24 is smaller than the thickness of a single grain, so that the moisture detection electrode plate 23 and the receiving plate 24 can crush a single grain.

[0046] The advantages of adopting the above-mentioned preferred solution are: the second driving device is conducive to moving the single grain that has been inspected for size on the imaging platform to be opposite to the moisture detection electrode plate; the third driving device is conducive to driving the moisture detection electrode plate to move, thereby cooperating with the feeding wheel in the second driving device to squeeze and break the single grain, and then obtaining the hardness of the single grain through the pressure sensor; the moisture detection electrode plate, through contact with the single grain, is conducive to detecting the moisture content of the single grain.

[0047] Preferred, such as Figure 6 and Figure 7 As shown, the second driving device 21 includes: a second servo motor 211, a second transmission box 212, and a feeding wheel 213. The second transmission box 212 is fixedly installed on the device frame 7. The input end of the second transmission box 212 is connected to the output shaft of the second servo motor 211. Its output end is vertically connected to the output shaft 214 of the second transmission box. The output shaft 214 of the second transmission box passes through the receiving plate 24. The feeding wheel 213 is located above the receiving plate 24 and is fixedly sleeved on the top end of the output shaft 214 of the second transmission box. Multiple toothed structures for feeding grain are spaced apart and fixedly installed on the circumferential sidewall of the feeding wheel 213.

[0048] It should be noted that in this embodiment, the second transmission box 212 is fixedly installed at the bottom end of the first mounting plate 72, and the second servo motor 211 is directly fixedly installed on the side wall of the second transmission box 212. Alternatively, the second servo motor 211 can be fixedly installed at the bottom end of the first mounting plate 72. "The second transmission box output shaft 214 passes through the receiving plate 24" means that the second transmission box output shaft 214 can rotate freely within the receiving plate 24 while passing through the receiving plate 24; When the feeding wheel 213 is positioned above the receiving plate 24, there is a gap between the bottom end of the feeding wheel 213 and the top end of the receiving plate 24, and this gap is smaller than the thickness of a single grain, so that the feeding wheel 213 can smoothly move a single grain. The receiving plate 24 has a notch, and the photographing platform 62 is adapted to be set in the notch. So when a single grain slides from the sliding block 61 into the photographing platform 62, it is also within the area covered by the feeding wheel 213 above the receiving plate 24.

[0049] The advantages of adopting the above preferred solution are: the second transmission box is conducive to transmitting the power output by the second servo motor to the output shaft of the second transmission box, and then to the feeding wheel through the output shaft of the second transmission box, driving the feeding wheel to rotate above the receiving plate, thereby moving the single grain on the imaging platform to be opposite to the moisture detection electrode plate.

[0050] Preferred, such as Figure 2 As shown, the size detection mechanism 3 includes a first camera 31 and a second camera 32. Both the first camera 31 and the second camera 32 are fixedly installed on the equipment frame 7. The first camera 31 is located above the photography platform 62, and the second camera 32 is located on the side of the photography platform 62.

[0051] It should be noted that in this embodiment, the first camera 31 is fixedly mounted on the first mounting block 34, and the first mounting block 34 is fixedly mounted on the top side wall of the column 33. The column 33 is vertical and fixedly mounted on the first mounting plate 72, so that the camera of the first camera 31 is aimed at the imaging platform 62. When there is a single grain on the imaging platform 62, a picture is taken from above the imaging platform 62 and the picture is transmitted to the controller. After the controller processes the information in the picture, it can obtain the length and width of the single grain. The second camera 32 is fixedly mounted on the first mounting plate 72 by the second mounting block 35, so that the camera of the second camera 32 is aimed at the photographing platform 62. When there is a single grain on the photographing platform 62, a picture is taken by taking a picture from the side of the photographing platform 62 and the picture is transmitted to the controller. After the controller processes the information of the picture, it can obtain the height (thickness) of the single grain.

[0052] The advantages of adopting the above-mentioned preferred solution are that the first camera and the second camera can take pictures from above and the side of a single grain, respectively, thereby obtaining the size of the single grain.

[0053] Preferred, such as Figures 2 to 4 As shown, the feeding mechanism 4 includes a feeding hopper 41 and a vibratory feeder 42. Both the feeding hopper 41 and the vibratory feeder 42 are fixedly installed on the equipment frame 7. The bottom end of the feeding hopper 41 is spaced above the vibratory feeder 42, and the outlet of the vibratory feeder 42 is spaced above the weight detection mechanism 1.

[0054] It should be noted that in this embodiment, the feeding hopper 41 is fixedly installed on the inner wall of the top of the outer shell 71, and the top of the feeding hopper 41 is connected to the top of the outer shell 71. The vibratory feeder 42 is fixedly installed on the first mounting plate 72. The vibratory feeder 42 is a prior art and can realize the single output of materials. The discharge port of the vibratory feeder 42 is spaced above the discharge hole 143.

[0055] The advantages of adopting the above-mentioned preferred solution are: the feed hopper is conducive to guiding multiple grains of grain from the outside into the vibratory feeder, and the vibratory feeder is conducive to outputting multiple grains of grain one by one.

[0056] Preferred, such as Figure 2 As shown, the discharge mechanism 5 includes a discharge hopper 51 and a receiving box 52. Both the discharge hopper 51 and the receiving box 52 are fixedly installed on the equipment frame 7. The top of the discharge hopper 51 is located below the hardness and moisture detection mechanism 2, and its bottom end is connected to the receiving box 52.

[0057] It should be noted that in this embodiment, the receiving box 52 is fixedly installed on the second mounting plate 73; the top end of the discharge hopper 51 is fixedly installed on the bottom end of the first mounting plate 72, the first mounting plate 72 is provided with a through hole communicating with the discharge hopper 51, one side of the receiving plate 24 is provided with a slope, and the lower part of the slope is located above the through hole. The toothed structure on the circumferential side wall of the feeding wheel 213 is located above the slope. When the toothed structure rotates with the feeding wheel 213 to the upper part of the slope, the broken grains of grain propelled by the toothed structure fall onto the slope under the action of gravity, and enter the discharge hopper 51 along the slope and through hole, and finally reach the receiving box 52 for storage.

[0058] The beneficial effect of adopting the above-mentioned preferred scheme is that the discharge hopper facilitates the guidance of the single grains that are broken after testing to the receiving box for storage.

[0059] The working process of this embodiment is described below: like Figures 1 to 7 As shown, the first step is to start the first servo motor 121 and drive the feeding cylinder 132 to rotate to directly above the weighing device 11. Step 2: Place multiple grains from the sample into the feed hopper 41 and feed them into the vibratory feeder 42. The vibratory feeder 42 then arranges and outputs the grains one by one through vibration and rotation. The first grain falls from the discharge port of the vibratory feeder 42 and passes through the discharge hole 143 and the feeding cylinder 132 in sequence, reaching the weighing device 11. During this process, when the material sensor 142 detects that a grain has fallen, the controller stops the operation of the vibratory feeder 42 to prevent the second grain from falling. Step 3: Start the first servo motor 121 and make the first servo motor 121 rotate forward and backward several times within a certain angle, thereby driving the feeding cylinder 132 to rotate back and forth several times within a certain angle directly above the weighing device 11. During this process, the inner wall of the feeding cylinder 132 moves the single grain back and forth on the weighing device 11, so that the single grain does not contact the inner wall of the feeding cylinder 132. At this time, the value detected by the weighing device 11 is the actual weight of the single grain. Step 4: Start the first servo motor 121, so that the feeding cylinder 132 pushes the single grain on the weighing device 11 toward the sliding block 61 until the single grain on the weighing device 11 is pushed to fall into the sliding groove of the sliding block 61 and slides down the sliding groove onto the imaging platform 62. At this time, the first camera 31 and the second camera 32 take pictures of the single grain and transmit the data to the controller for processing, so as to obtain the size (length, width and height) of the single grain. Step 5: Start the second servo motor 211 to drive the feeding wheel 213 to rotate, and move the single grain on the imaging platform 62 to the position on the receiving plate 24 opposite to the moisture detection electrode plate 23, and then stop. Step 6: Start the third drive device 22 to drive the moisture detection electrode plate 23 to move toward the feeding wheel 213 until the moisture detection electrode plate 23 and the feeding wheel 213 clamp and fix the single grain. Then continue to slowly drive the moisture detection electrode plate 23 toward the feeding wheel 213 until the single grain breaks. The pressure value of the single grain when it breaks is recorded by the pressure sensor in the third drive device 22, and the hardness of the single grain is characterized by this. At the same time, since the moisture detection electrode plate 23 is in contact with the single grain, the moisture content of the single grain can be detected. Step 7: Start the second servo motor 211 to drive the feeding wheel 213 to rotate again, and push the broken single grains to the top of the discharge hopper 51. Under the action of gravity, they enter the discharge hopper 51 and reach the receiving box 52 along the discharge hopper 51.
