Description

Technical Field

[0001] The present invention belongs to the technical field of grain humidity detection and relates to a grain humidity detection device. Background Art

[0002] During the process of purchasing grains, it is crucial to detect the humidity of grains. Accurate detection results are of great significance for the reasonable pricing, safe storage, and subsequent processing and utilization of grains. During the process of detecting grains, in order to reduce errors and ensure the accuracy of the detection results, multiple detections are usually required, and then the evaluation is carried out based on the multiple detection results. However, during the detection process, a certain amount of samples need to be placed on the moisture detector. After the detection is completed, the samples on the moisture detector need to be taken away and then new samples are placed, which is time-consuming and laborious and is not conducive to improving the detection efficiency.

[0003] The invention patent with the publication number of CN115753839A discloses a moisture detection and weighing device for solid particle inspection, including a fixed cabinet. Two fixing plates are arranged up and down inside the fixed cabinet, and a feeding frame is arranged below the inside of the fixed cabinet. This invention utilizes the first electric sliding table, feeding frame, and rotating frame structures in the feeding component, enabling solid particles to be automatically transported to the weighing process and the moisture detection process without manual assistance, and the transportation between adjacent processes is fast, significantly improving the efficiency of moisture detection and weighing detection of solid particles.

[0004] However, the following deficiencies exist in the use of this invention: when collecting the samples after the detection is completed, the samples in the detection tank need to be pumped away before new samples can be placed in the detection tank; after placing new samples, the samples in the detection tank need to be leveled, which is not conducive to improving the detection efficiency. Therefore, there is an urgent need to design a grain humidity detection device that is easy to use and improves the detection efficiency. Summary of the Invention

[0005] To solve the problems in the background art, the present invention proposes a grain humidity detection device.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

A slideway communicating with the sliding hole is arranged on the detection table, and a slider is slidably arranged in the slideway. The slider is in sliding contact with the bottom end of the slideway. A storage hole for accommodating a grain sample is formed in the slider. Collection hoppers are arranged at both ends of the detection table. A first driving assembly for driving the slider is arranged on the slideway. When the detection table moves upward, the slider moves along the slideway, and the grain sample in the storage hole enters the sliding hole, and the moisture detector detects the grain sample in the sliding hole.

[0018] 1. Through the reciprocating movement of the slider on the slideway and the up and down movement of the detection table in cooperation, the samples in the storage holes can be automatically divided into batches and enter the slide holes for detection, which is beneficial to improving the accuracy of the detection results and the detection efficiency. At the same time, the detected grain samples are automatically pushed by the slider into the collection hopper, improving the overall convenience of use.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1-11 shown, the technical solution adopted by the present invention is as follows:

[0035] The grain humidity detection device includes a mounting shell 1, a detection table 25, a moisture detector 35, a slider 30 and a cloth bag 18. The detection table 25 is vertically movable and arranged at the bottom of the mounting shell 1. Specifically, a hydraulic rod 24 is fixedly installed at the bottom of the mounting shell 1, the output end of the hydraulic rod 24 is vertically upward, and the detection table 25 is fixedly connected to the output end of the hydraulic rod 24. The detection table 25 is T-shaped. A sliding hole is formed in the vertical part of the detection table 25, the moisture detector 35 is installed at the bottom of the mounting shell 1 and located in the sliding hole, and the moisture detector 35 is slidably matched with the sliding hole. The moisture detector 35 is used to detect the humidity of the grain sample in the sliding hole.

[0036] Preferably, the number of the hydraulic rods 24 here is two, and the two hydraulic rods 24 are symmetrically arranged with respect to the vertical part of the detection table 25.

[0037] A slideway 26 is formed in the horizontal part of the detection table 25, the slideway 26 penetrates through the left and right ends of the detection table 25, and the sliding hole is communicated with the slideway 26. The slider 30 is slidably arranged in the slideway 26.

[0038] A first driving component for driving the slider 30 to slide in the slideway 26 is arranged on the detection table 25. The first driving component includes a second electric slide rail 34, a slide table matched with the second electric slide rail 34 is fixedly connected with a connecting plate 33, and the slider 30 is fixedly connected with the connecting plate 33. The second electric slide rail 34 drives the slider 30 to reciprocate left and right in the slideway 26 through the connecting plate 33.

[0039] A storage hole 32 is formed in the slider 30. The storage hole 32 is used for holding the grain sample to be detected. The lower end of the storage hole 32 is adapted to the sliding hole.

[0040] Collection hoppers 36 are arranged in a matching manner at both the left and right ends of the detection table 25. The collection hoppers 36 are used for collecting the detected grain samples. The collection hoppers 36 are slidably arranged in the mounting shell 1. An outlet matched with the collection hopper 36 is arranged on the mounting shell 1, so that the collection hopper 36 can be pulled out of the mounting shell 1.

[0041] A first contact 27, a second contact 28 and a third contact 29 are successively arranged at intervals along the length direction on one inner wall of the slideway 26. The second contact 28 is located between the first contact 27 and the third contact 29 and corresponds to the position of the sliding hole. A fourth contact 31 is installed on the side wall of the slider 30. The slider 30 slides on the slideway 26. When the fourth contact 31 contacts the second contact 28, the hydraulic rod 24 extends a certain length, and the detection table 25 moves up a certain distance. When the fourth contact 31 contacts the first contact 27 or the third contact 29, the hydraulic rod 24 shortens, the detection table 25 moves down, and the upper end surface of the moisture detector 35 is flush with the bottom end of the slideway 26.

[0042] The grain sample to be tested is placed into the storage hole 32. The second motorized slide 34 then slides the slider 30 along the slideway 26. When the fourth contact 31 contacts the second contact 28, the hydraulic lever 24 is activated, moving the testing platform 25 upward a certain distance. As the storage hole 32 passes the slideway, the grain sample falls into the slideway above the moisture detector 35. When the storage hole 32 is offset from the slideway, the slideway is filled with the grain sample, and the moisture detector 35 performs a moisture test on the grain sample. When the fourth contact 31 contacts the first contact 27 or the third contact 29, the slider 30 has fully moved to one side of the slideway. The hydraulic lever 24 is then activated, moving the testing platform 25 downward until the upper surface of the moisture detector 35 is flush with the bottom of the slideway 26. When the slider 30 passes the slideway again, it pushes the grain sample on the moisture detector 35 and places it into the corresponding collection hopper 36.

[0043] A sliding frame 4 is mounted on the mounting housing 1 for left and right movement. The mounting housing 1 defines a limit slot within which the sliding frame 4 slides within a limited position. A first electric slide rail 2 is fixedly mounted on the mounting housing 1, and a slide platform associated with the first electric slide rail 2 is fixedly connected to the sliding frame 4. The first electric slide rail 2 drives the sliding frame 4 to slide left and right.

[0044] A fourth rotating shaft 17 is rotatably mounted on the sliding frame 4. The fourth rotating shaft 17 is arranged horizontally and is fixedly connected to a collar 16, with the axis of the collar 16 being perpendicular to the axis of the fourth rotating shaft 17. The opening of a cloth bag 18 is fixedly connected to the collar 16, so that a grain sample is placed into the cloth bag 18 through the collar 16; the cloth bag 18 moves left and right with the sliding frame 4, thereby causing the cloth bag 18 to move to one end of the mounting housing 1.

[0045] Mounted on the carriage 4 is a second drive assembly that causes the collar 16 to swing back and forth. Blocking plates 23 are fixedly mounted on both the front and rear sides of the mounting housing 1. The swinging of the collar 16 drives the cloth bag 18 back and forth, causing it to strike the blocking plates 23, breaking up any clumped grain sample inside the bag and improving the accuracy of the test results.

[0046] The second drive assembly includes a second rotating shaft 9, a rotating rod 10, and a rocker arm 13. The second rotating shaft 9 is rotatably mounted on the sliding frame 4. One end of the rotating rod 10 is fixedly connected to the second rotating shaft 9, and the other end of the rotating rod 10 is connected to the sliding shaft 11. A third rotating shaft 12 is rotatably mounted on the sliding frame 4, and one end of the rocker arm 13 is fixedly connected to the third rotating shaft 12. The rocker arm 13 has a slide groove 14 defined therein, and the sliding shaft 11 is slidably disposed within the slide groove 14. A first motor 15 is fixedly mounted on the rocker arm 13, and the motor shaft of the first motor 15 is fixedly connected to the fourth rotating shaft 17. The third rotating shaft 12 and the fourth rotating shaft 17 are coaxially arranged.

[0047] The sliding carriage 4 and the second rotating shaft 9 are linked, that is, a linkage component is provided between the sliding carriage 4 and the second rotating shaft 9. The linkage component includes a rack 3, a gear 6, a worm 7 and a worm gear 8. A first rotating shaft 5 is rotatably installed on the sliding carriage 4. One end of the first rotating shaft 5 is fixedly connected to the gear 6. The gear 6 meshes with the rack 3. The rack 3 is fixedly arranged on the mounting shell 1. The other end of the first rotating shaft 5 is fixedly connected to the worm 7. The worm gear 8 meshes with the worm 7 and the worm gear 8 is coaxially and fixedly connected to the second rotating shaft 9.

[0048] When the sliding carriage 4 moves left and right, under the action of the gear 6 and the rack 3, the first rotating shaft 5 rotates. Through the action of the worm 7 and the worm gear 8, the second rotating shaft 9 rotates. The rotating rod 10 drives the swing rod 13 to swing back and forth, causing the collar 16 to swing back and forth.

[0049] Limit bags 19 are fixedly connected to both the left and right sides of the cloth bag 18. A plug rod 20 is slidably arranged in each limit bag 19. The upper end of the plug rod 20 slides upward through the collar 16 and extends above the collar 16.

[0050] Drive rollers 22 are arranged on both sides of the plug rod 20. The drive rollers 22 are in frictional contact with the plug rod 20. The drive rollers 22 are rotatably installed on the collar 16, and a second motor 21 matched with the drive rollers 22 is installed on the collar 16. The second motor 21 drives the drive rollers 22 to rotate, and the drive rollers 22 drive the plug rod 20 to slide in the limit bag 19.

[0051] When the plug rod 20 extends to the bottom of the limit bag 19, the first motor 15 is started. The first motor 15 drives the fourth rotating shaft 17 to rotate. The collar 16 rotates around the fourth rotating shaft 17, and then the mouth of the cloth bag 18 faces downward, pouring out the grain sample in the cloth bag 18. The plug rod 20 plays a supporting role for the cloth bag 18, which is beneficial to smoothly pouring out the grain sample in the cloth bag 18.

[0052] As Figure 1 、 Figure 2 shown, there is a gap between the right end of the rack 3 and the right end of the mounting shell 1, and there is a gap between the right end of the baffle 23 and the right end of the mounting shell 1. When the sliding carriage 4 moves to the right end of the mounting shell 1, the gear 6 disengages from the rack 3, and the collar 16 stops swinging. Then, the plug rod 20 extends to the bottom of the limit bag 19, and the plug rod 20 plays a supporting role for the cloth bag 18. By driving the fourth rotating shaft 17 to rotate through the first motor 15, the collar 16 rotates around the fourth rotating shaft 17; the plug rod 20 and the cloth bag 18 both rotate around the fourth rotating shaft 17, making the mouth of the cloth bag 18 gradually face downward, and the grain sample in the cloth bag 18 is gradually poured out. There is a gap between the right end of the baffle 23 and the right end of the mounting shell 1, providing space for the movement of the cloth bag 18 and ensuring the smooth rotation of the cloth bag 18.

[0053] The working principle of the present invention:

[0054] Initially, as Figure 2 and Figure 9 shown, the slider 30 is at the right end of the mounting shell 1, and the sliding frame 4 is at the left end of the mounting shell 1. The upper end surface of the moisture detector 35 is flush with the bottom end of the slideway 26.

[0055] Then, pour the grain sample to be detected into the cloth bag 18 through the collar 16.

[0056] Then, move the sliding frame 4 to the right, and the sliding frame 4 drives the cloth bag 18 to move towards the slider 30.

[0057] When the sliding frame 4 moves to the right, under the action of the rack 3, the gear 6 drives the first rotating shaft 5 to rotate, the first rotating shaft 5 drives the worm 7 to rotate, the worm 7 drives the worm gear 8 to rotate, the worm 7 drives the second rotating shaft 9 to rotate, the rotating rod 10 rotates around the second rotating shaft 9, the sliding shaft 11 slides in the sliding groove 14, and the rotating rod 10 drives the swing rod 13 to swing back and forth around the third rotating shaft 12. The swing rod 13 drives the first motor 15, the fourth rotating shaft 17 and the collar 16 to swing back and forth, so that the cloth bag 18 swings back and forth and impacts the blocking plate 23, and the agglomerated grain sample in the cloth bag 18 is broken up, so that the broken grain sample can be mixed evenly with other grains, improving the uniformity of the grain sample and being beneficial to improving the accuracy of the detection result.

[0058] It should be noted that before starting the sliding frame 4, the second motor 21 can be started to make the driving roller 22 rotate; the two driving rollers 22 rotate in opposite directions to make the insertion rod 20 move upward, so as to ensure that the cloth bag 18 can move freely and make the movement amplitude of the cloth bag 18 larger; at the same time, when the cloth bag 18 impacts the blocking plate 23, the cloth bag 18 may also shake and rotate, so that the grain sample in the cloth bag 18 is more fully disturbed, so as to more effectively break up the agglomerated grain sample and promote uniform mixing with other grain samples.

[0059] When the gear 6 disengages from the rack 3, the first rotating shaft 5 stops rotating, the second rotating shaft 9 stops rotating, and the cloth bag 18 stops swinging back and forth. When the collar 16 moves to directly above the storage hole 32, stop moving the sliding frame 4. Start the second motor 21, the driving roller 22 rotates, make the insertion rod 20 move into the limiting bag 19, the insertion rod 20 inserts into the bottom of the limiting bag 19, and the insertion rod 20 has a supporting effect on the cloth bag 18. Then, start the first motor 15, the collar 16 rotates around the fourth rotating shaft 17, the cloth bag 18 and the insertion rod 20 rotate around the fourth rotating shaft 17, so that the mouth of the cloth bag 18 gradually faces downward, and the grain sample in the cloth bag 18 flows downward and into the storage hole 32.

[0060] After the food sample in the cloth bag 18 is poured out, the fourth rotating shaft 17 is driven to rotate by the first motor 15 to reset the cloth bag 18. Then, the sliding frame 4 moves to the left end of the mounting shell 1, so that the cloth bag 18 moves to the left end of the mounting shell 1.

[0061] The second electric slide 34 is activated, causing the slider 30 to move toward the left end of the mounting housing 1. This causes the slider 30 to move the grain sample in the storage hole 32 to the left. When the fourth contact 31 contacts the second contact 28, the hydraulic rod 24 extends, pushing the testing platform 25 upward a certain distance, causing the moisture detector 35 to be a certain distance below the bottom of the slide 26. As the slider 30 moves, the storage hole 32 connects with the slide hole, and the grain sample in the storage hole 32 falls into the slide hole and is positioned above the moisture detector 35. As the slider 30 moves leftward, the storage hole 32 gradually shifts away from the slide hole, and the slide hole above the moisture detector 35 is filled with the grain sample. The moisture detector 35 then performs a moisture test on the grain sample in the slide hole.

[0062] As the slider 30 moves left, its right end moves to the left of the slide hole. When the fourth contact 31 contacts the first contact 27, the hydraulic rod 24 shortens, and the detection platform 25 moves downward until the upper surface of the moisture detector 35 is flush with the bottom of the slide 26. The storage hole 32 on the slider 30 moves rightward and gradually approaches the slide hole. As the slider 30 moves rightward, its right end pushes the grain sample on the moisture detector 35, thereby removing it from the moisture detector 35.

[0063] When the fourth contact 31 contacts the second contact 28, the hydraulic rod 24 extends, and the detection platform 25 moves upward a certain distance, positioning the moisture detector 35 below the slide 26. As the slide 30 moves rightward, the storage hole 32 passes the sliding hole, and the grain sample in the storage hole 32 falls into the sliding hole above the moisture detector 35. When the storage hole 32 and the sliding hole are offset, the sliding hole is filled with the grain sample, and the moisture detector 35 performs a moisture test on the grain sample in the sliding hole.

[0064] As the slider 30 moves rightward, its left end moves to the right side of the slide hole. When the fourth contact 31 contacts the third contact 29, the hydraulic rod 24 shortens, the detection platform 25 moves downward, and the upper end surface of the moisture detector 35 is flush with the bottom end of the slide 26. At this point, the grain sample at the right end of the slider 30 has been pushed into the collection hopper 36 on the right side.

[0065] Then, the slider 30 starts to move leftward. During the leftward movement of the slider 30, when the storage hole 32 passes through the sliding hole, the grain sample in the storage hole 32 enters the sliding hole, and the moisture detector 35 detects the grain sample in the sliding hole. During the leftward movement of the slider 30, the left end of the slider 30 pushes the grain sample on the moisture detector 35 leftward and drops it into the collecting hopper 36 on the left side.

[0066] Accordingly, as the slider 30 reciprocates left and right in the slideway 26 and moves up and down in cooperation with the detection table 25, the grain samples in the storage holes 32 fall into the sliding holes in batches, thereby realizing the automatic batch detection of the grain samples, which is beneficial to improving the accuracy of the detection results. The detected grain samples are automatically pushed into the collecting hopper 36 for collection, eliminating the need for manual picking and placing of the grain samples and improving the detection efficiency.

[0067] The grain humidity detection device in the present invention can automatically detect the grain in batches and can also automatically collect the detected grain, improving the detection efficiency and being beneficial to improving the accuracy of the detection results.

[0068] When performing humidity detection, the thickness of the grain sample usually needs to be controlled within a certain range to ensure the accuracy and reliability of the detection results. In this detection device, by controlling the extended length of the hydraulic rod 24, that is, the height of the upward movement of the detection table 25, the thickness of the grain entering the sliding hole is controlled, so as to be applicable to different grains.

[0069] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
