DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 11 As shown, the technical solution adopted by the present invention is as follows: The grain moisture detection device includes a mounting shell 1, a detection platform 25, a moisture detector 35, a slider 30 and a cloth bag 18. The detection platform 25 is arranged at the bottom of the mounting shell 1 so as to move up and down. Specifically, a hydraulic rod 24 is fixedly installed at the bottom of the mounting shell 1, and the output end of the hydraulic rod 24 is vertically upward, and the detection platform 25 is fixedly connected to the output end of the hydraulic rod 24. The detection platform 25 is T-shaped. A sliding hole is provided on the vertical portion of the detection platform 25, and the moisture detector 35 is mounted at the bottom of the mounting shell 1 and is located in the sliding hole, and the moisture detector 35 slides with the sliding hole. The moisture detector 35 is used to detect the moisture of the grain sample in the sliding hole.

[0023] The number of the hydraulic rods 24 here is preferably two, and the two hydraulic rods 24 are symmetrically arranged relative to the vertical portion of the testing platform 25 .

[0024] A slideway 26 is provided on the horizontal portion of the detection platform 25 , and the slideway 26 runs through the left and right ends of the detection platform 25 , and the slide hole is connected to the slideway 26 . The slider 30 is slidably disposed in the slideway 26 .

[0025] The detection table 25 is provided with a first driving assembly for driving the slider 30 to slide in the slideway 26. The first driving assembly includes a second electric slide rail 34, and 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 move back and forth in the slideway 26 through the connecting plate 33.

[0026] The slide block 30 is provided with a storage hole 32. The storage hole 32 is used to hold the grain sample to be tested. The lower end of the storage hole 32 is adapted to the slide hole.

[0027] The left and right ends of the detection platform 25 are equipped with a collection bucket 36, which is used to collect the tested grain samples. The collection bucket 36 is slidably arranged in the mounting shell 1. The mounting shell 1 is provided with an outlet matching the collection bucket 36, so that the collection bucket 36 can be pulled out of the mounting shell 1.

[0028] On the inner wall of one side of the slideway 26, a first contact 27, a second contact 28 and a third contact 29 are installed in sequence along the length direction. The second contact 28 is located between the first contact 27 and the third contact 29 and corresponds to the position of the slide 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 moves the detection platform 25 up a certain distance. When the fourth contact 31 contacts the first contact 27 or the third contact 29, the hydraulic rod 24 shortens, moves the detection platform 25 down, and makes the upper end surface of the moisture detector 35 flush with the bottom end of the slideway 26.

[0029] The grain sample to be tested is placed in the storage hole 32, and the slider 30 is slid along the slideway 26 by the second electric slide rail 34; when the fourth contact 31 contacts the second contact 28, the hydraulic rod 24 is activated to move the detection platform 25 up a certain distance. When the storage hole 32 passes through the slide hole, the grain sample in the storage hole 32 falls into the slide hole above the moisture detector 35. When the storage hole 32 is staggered with the slide hole, the slide hole is filled with grain samples, and the moisture detector 35 performs humidity detection on the grain sample in the slide hole. When the fourth contact 31 contacts the first contact 27 or the third contact 29, the slider 30 has completely moved to one side of the slide hole, and then the hydraulic rod 24 is activated to move the detection platform 25 downward until the upper end surface of the moisture detector 35 is flush with the bottom end of the slideway 26. When the slider 30 passes through the slide hole again, it will push the grain sample on the moisture detector 35 to move and push the grain sample on the moisture detector 35 into the corresponding collection bucket 36.

[0030] A sliding frame 4 is installed on the installation shell 1 for left and right movement. A limit groove is provided on the installation shell 1, and the sliding frame 4 is set in the limit groove for limited sliding. A first electric slide rail 2 is fixedly installed on the installation shell 1, and a slide table matched 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.

[0031] The fourth rotating shaft 17 is rotatably mounted on the sliding frame 4, and the fourth rotating shaft 17 is horizontally arranged. The fourth rotating shaft 17 is fixedly connected with a collar 16, and the axis of the collar 16 is perpendicular to the axis of the fourth rotating shaft 17. The bag mouth of the cloth bag 18 is fixedly connected with the collar 16, so that the grain sample is put into the cloth bag 18 through the collar 16; the cloth bag 18 moves left and right with the sliding frame 4, and then the cloth bag 18 moves to one end of the mounting shell 1.

[0032] The second driving assembly for swinging the collar 16 back and forth is mounted on the sliding frame 4. Blocking plates 23 are fixedly mounted on both the front and rear sides of the mounting shell 1. When the collar 16 swings back and forth, it drives the cloth bag 18 to swing back and forth, and then the cloth bag 18 hits the blocking plate 23, breaking up the agglomerated grain sample in the cloth bag 18, which is beneficial to improving the accuracy of the detection result.

[0033] The second driving assembly includes a second rotating shaft 9, a rotating rod 10 and a swing rod 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. The third rotating shaft 12 is rotatably mounted on the sliding frame 4, and one end of the swing rod 13 is fixedly connected to the third rotating shaft 12. A sliding groove 14 is provided on the swing rod 13, and the sliding shaft 11 is slidably arranged in the sliding groove 14. A first motor 15 is fixedly mounted on the swing rod 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.

[0034] The sliding frame 4 and the second rotating shaft 9 are arranged in linkage, that is, a linkage assembly is arranged between the sliding frame 4 and the second rotating shaft 9. The linkage assembly includes a rack 3, a gear 6, a worm 7 and a worm wheel 8. The first rotating shaft 5 is rotatably mounted on the sliding frame 4, one end of the first rotating shaft 5 is fixedly connected to the gear 6, the gear 6 is meshed with the rack 3, and 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 wheel 8 is meshed with the worm 7, and the worm wheel 8 is coaxially fixedly connected to the second rotating shaft 9.

[0035] When the sliding frame 4 moves left and right, the first rotating shaft 5 rotates under the action of the gear 6 and the rack 3, and the second rotating shaft 9 rotates through the action of the worm 7 and the worm wheel 8, and the rotating rod 10 drives the swing rod 13 to swing back and forth, so that the ring 16 swings back and forth.

[0036] The left and right sides of the cloth bag 18 are fixedly connected to the limiting bags 19 , and each limiting bag 19 is slidably provided with an insertion rod 20 , and the upper end of the insertion rod 20 slides upward to penetrate the ring 16 and extend to the top of the ring 16 .

[0037] A driving roller 22 is provided on both sides of the insertion rod 20, and the driving roller 22 is in frictional contact with the insertion rod 20. The driving roller 22 is rotatably mounted on the collar 16, and a second motor 21 matching the driving roller 22 is mounted on the collar 16. The second motor 21 drives the driving roller 22 to rotate, and the driving roller 22 drives the insertion rod 20 to slide in the limiting bag 19.

[0038] When the insertion rod 20 is inserted into the bottom of the limiting bag 19, the first motor 15 is started, the first motor 15 drives the fourth rotating shaft 17 to rotate, and the ring 16 rotates around the fourth rotating shaft 17, so that the bag mouth of the cloth bag 18 is downward, and the grain sample in the cloth bag 18 is poured out. The insertion rod 20 supports the cloth bag 18, which is conducive to pouring out the grain sample in the cloth bag 18 smoothly.

[0039] like Figure 1 , Figure 2 As 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 blocking plate 23 and the right end of the mounting shell 1. When the sliding frame 4 moves to the right end of the mounting shell 1, the gear 6 disengages from the rack 3, and the ring 16 stops swinging. Then, the insertion rod 20 extends into the bottom of the limiting bag 19, and the insertion rod 20 supports the cloth bag 18. The fourth rotating shaft 17 is driven to rotate by the first motor 15, so that the ring 16 rotates around the fourth rotating shaft 17; the insertion rod 20 and the cloth bag 18 both rotate around the fourth rotating shaft 17, so that the bag mouth of the cloth bag 18 gradually moves downward, and the grain sample in the cloth bag 18 is gradually poured out. There is a gap between the right end of the blocking plate 23 and the right end of the mounting shell 1, which provides space for the movement of the cloth bag 18 and ensures the smooth rotation of the cloth bag 18.

[0040] Working principle of the present invention: Initially, if Figure 2 , Fig. 9 As shown, the slider 30 is located at the right end of the mounting shell 1, and the sliding frame 4 is located 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.

[0041] Then, the grain sample to be tested is poured into the cloth bag 18 through the sleeve ring 16 .

[0042] Then, the sliding frame 4 is moved to the right, and the sliding frame 4 drives the cloth bag 18 to move toward the direction close to the slider 30 .

[0043] 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 wheel 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 hits 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 evenly mixed with other grains, thereby improving the uniformity of the grain sample, which is conducive to improving the accuracy of the detection result.

[0044] It should be noted that before starting the sliding frame 4, the second motor 21 can be started to rotate the driving roller 22; the two driving rollers 22 rotate in opposite directions and move the insertion rod 20 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 hits 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, thereby more effectively breaking up the agglomerated grain sample and promoting uniform mixing with other grain samples.

[0045] When the gear 6 is disengaged 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 the top of the storage hole 32, the sliding frame 4 stops moving. The second motor 21 is started, and the driving roller 22 rotates, so that the insertion rod 20 moves into the limiting bag 19, and the insertion rod 20 is inserted into the bottom of the limiting bag 19, and the insertion rod 20 has a supporting effect on the cloth bag 18. Then, the first motor 15 is started, the collar 16 rotates around the fourth rotating shaft 17, and the cloth bag 18 and the insertion rod 20 rotate around the fourth rotating shaft 17, so that the bag mouth of the cloth bag 18 gradually moves downward, and the food sample in the cloth bag 18 flows downward and flows into the storage hole 32.

[0046] 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.

[0047] The second electric slide rail 34 is started to move the slider 30 toward the left end of the mounting shell 1. The slider 30 drives the grain sample in the storage hole 32 to move to the left. When the fourth contact 31 contacts the second contact 28, the hydraulic rod 24 extends, and the hydraulic rod 24 pushes the detection platform 25 to move up a certain distance. The moisture detector 35 is below the bottom of the slideway 26 by a certain distance. As the slider 30 moves, the storage hole 32 is connected to the slide hole, and the grain sample in the storage hole 32 falls into the slide hole and is located above the moisture detector 35. As the slider 30 moves to the left, the storage hole 32 gradually staggers with the slide hole, and the slide hole above the moisture detector 35 is filled with grain samples. The moisture detector 35 performs humidity detection on the grain sample in the slide hole.

[0048] As the slider 30 moves to the left, the right end of the slider 30 moves to the left side 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 down until the upper end surface of the moisture detector 35 is flush with the bottom end of the slide 26. The storage hole 32 on the slider 30 moves to the right and gradually approaches the slide hole. During the movement of the slider 30 to the right, the right end of the slider 30 can push the grain sample on the moisture detector 35, thereby pushing the grain sample on the moisture detector 35 away from the moisture detector 35.

[0049] When the fourth contact 31 contacts the second contact 28, the hydraulic rod 24 extends, the detection platform 25 moves up a certain distance, and the moisture detector 35 is located below the slide 26. As the slider 30 moves to the right, when the storage hole 32 passes through the slide hole, the grain sample in the storage hole 32 falls into the slide hole above the moisture detector 35. When the storage hole 32 is offset from the slide hole, the slide hole is filled with grain samples, and the moisture detector 35 performs humidity detection on the grain sample in the slide hole.

[0050] As the slider 30 moves to the right, the left end of the slider 30 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 down, and the upper end surface of the moisture detector 35 is flush with the bottom end of the slideway 26. At this time, the grain sample at the right end of the slider 30 has been pushed into the collection bucket 36 on the right side.

[0051] Then, the slider 30 starts to move to the left. 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. When the slider 30 moves to the left, the left end of the slider 30 pushes the grain sample on the moisture detector 35 to the left and pushes it into the collection bucket 36 on the left.

[0052] Accordingly, as the slider 30 reciprocates left and right in the slideway 26 and moves up and down in coordination with the detection platform 25, the grain samples in the storage hole 32 fall into the slide hole in batches, thereby automatically detecting the grain samples in batches, which is beneficial to improving the accuracy of the detection results. The detected grain samples are automatically pushed into the collection bucket 36 for collection, and there is no need to manually take and place the grain samples, thereby improving the detection efficiency.

[0053] The grain moisture detection device in the present invention can automatically detect grains in batches and can also automatically collect the detected grains, thereby improving the detection efficiency and facilitating improving the accuracy of the detection results.

[0054] 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 result. In this detection device, the thickness of the grain entering the slide hole is controlled by controlling the length of the hydraulic rod 24, that is, the height of the detection platform 25 moving upward, so as to be suitable for different grains.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
