[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Please see Figure 1-3This utility model provides a sample crusher for seed processing, including a casing 1. A servo motor 33 is fixedly connected to the top of the casing 1. A second rotating shaft 6 is fixedly connected to the output shaft of the servo motor 33. A sleeve 20 is slidably sleeved on the outer surface of the second rotating shaft 6, and a pin 19 is fixedly inserted into the inside of the sleeve 20. A sliding opening is provided on the outer surface of the second rotating shaft 6, and the pin 19 is slidably disposed inside the sliding opening. A sleeve plate 21 is rotatably sleeved on the outer surface of the sleeve 20 through a bearing. A connecting block 22 is fixedly connected to one side of the sleeve plate 21. Two symmetrical guide rails 27 are fixedly connected to the inner wall of the casing 1, and the two ends of the connecting block 22 are... The components are respectively slidably inserted into the interior of two guide rails 27. A support plate 17 is fixedly connected inside the chassis 1. A fourth rotating shaft 14 and a fifth rotating shaft 18 are rotatably connected to one side of the support plate 17. A second synchronous pulley 15 is fixedly sleeved on the outer surface of both the fourth rotating shaft 14 and the fifth rotating shaft 18. A second synchronous belt 16 is sleeved between the two second synchronous pulleys 15 through toothed grooves. A turntable 24 is fixedly connected to one end of the fifth rotating shaft 18. A sliding column 23 is fixedly connected to one side of the turntable 24. A sliding groove is provided on one side of the connecting block 22, and the sliding column 23 is slidably inserted into the groove. One end of the fourth rotating shaft 14 and the second rotating shaft 18 are connected to the second synchronous belt 16. A bevel gear 13 is fixedly sleeved on the outer surface of shaft 6, and two bevel gears 13 mesh with each other. A hammer plate 28 is fixedly connected to the bottom of sleeve 20, and multiple circular blocks are fixedly connected to the bottom of both sides of the hammer plate 28. A crushing blade 29 is fixedly connected to the bottom of the second rotating shaft 6, and the bottom end of the second rotating shaft 6 is slidably inserted into the top of the hammer plate 28. A sieve plate 30 is fixedly connected inside the machine housing 1, and a feeding hopper 31 is fixedly connected to the bottom of the inner cavity of the machine housing 1. A material outlet 32 is opened at the bottom of the machine housing 1. An intermittent feeding mechanism is provided at the top of the machine housing 1. When the seed sample is fed into the interior of the machine housing 1, the servo motor 33 is activated to utilize... The insertion of the second rotating shaft 6 and the insert 19 causes the sleeve 20 to rotate synchronously with the second rotating shaft 6, thereby crushing the seed sample on the top of the sieve plate 30 using the rotation of the hammer plate 28 and the crushing blade 29. At the same time, the rotation of the two bevel gears 13 causes the turntable 24 to drive the sliding column 23 to slide back and forth inside the sliding groove, thereby causing the connecting block 22 to drive the sleeve 20 to slide back and forth on the outer surface of the second rotating shaft 6. Thus, when the hammer plate 28 rotates, multiple circular blocks can reciprocate to impact the seed sample on the top of the sieve plate 30, thereby improving the crushing efficiency of the seed sample. The crushed seed sample can be discharged and collected through the feeding hopper 31 to the material outlet 32.
[0022] It should be noted that, in order to further improve the crushing efficiency, the intermittent feeding mechanism includes a feed inlet 4, which is located at the top of the casing 1, and a hopper 3 is fixedly connected to the top of the feed inlet 4. A first rotating shaft 5 and a third rotating shaft 7 are rotatably connected to the top of the inner cavity of the casing 1, and a first synchronous pulley 8 is fixedly sleeved on the outer surface of both the first rotating shaft 5 and the third rotating shaft 7. A first synchronous belt 9 is connected between the two first synchronous pulleys 8 through tooth grooves. A first spur gear 11 is fixedly sleeved on the bottom end of the first rotating shaft 5, and a second spur gear 12 is fixedly sleeved on the outer surface of the second rotating shaft 6. The second spur gear 12 meshes with the third rotating shaft 7. The bottom end of the third rotating shaft 7 is fixedly connected to the control plate 10, and the bottom end of the feed inlet 4 is in contact with the top of the control plate 10. The outer surface of the control plate 10 is provided with a notch, which is rotatably located directly below the bottom end of the feed inlet 4. Thus, when the seed sample is placed inside the hopper 3, the rotation of the second rotating shaft 6 causes the first rotating shaft 5 to rotate at a reduced speed. This causes the two first synchronous pulleys 8 and the first synchronous belt 9 to rotate at a reduced speed when driving the control plate 10 to rotate. By utilizing the notch of the reduced speed rotation, the seed sample is accelerated to crush during the intermittent feeding of the comparison seed sample.
[0023] To improve the crushing efficiency of seed samples, the bottoms of the multiple circular blocks and the crushing blades 29 are in contact with the top of the sieve plate 30, and the hammer plate 28 and the crushing blades 29 are rotatably mounted on the top of the sieve plate 30. The gear ratio of the first spur gear 11 and the second spur gear 12 is 3:1.
[0024] In order to reduce the speed of the material control plate 10 and to ensure that the rotation of the second rotating shaft 6 is not affected by the first synchronous belt 9, the second rotating shaft 6 is rotatably disposed between the first rotating shaft 5 and the third rotating shaft 7, and the second rotating shaft 6 is rotatably disposed inside the first synchronous belt 9, and the first spur gear 11 and the second spur gear 12 are rotatably disposed below the first synchronous belt 9.
[0025] In order to improve the stable sliding of the sleeve 20 outside the second rotating shaft 6, both ends of the insert 19 are fixed with limiting pieces 25, and the adjacent sides of the two limiting pieces 25 are in contact with the outer surface of the sleeve 20.
[0026] In order to ensure that the connecting block 22 can slide stably and that the two guide rails 27 do not interfere with the rotation and lifting of the hammer plate 28, both guide rails 27 are located above one side of the hammer plate 28, and the bottom of the two guide rails 27 is higher than the top of the sliding opening, and the hammer plate 28 is slidably disposed on one side of the two guide rails 27.
[0027] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0028] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0029] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
