Obviously, the described embodiments are 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.

[0018] A wood shavings raw material bin discharging device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, it includes a silo 1, the bottom of the silo 1 is open and is equipped with a sealing cover 2, a feed hopper 13 is connected and installed on the silo 1, a vertical shaft 3 is rotatably installed in the silo 1, one end of the vertical shaft 3 is rotatably connected to the inner wall of the reserved hole on the silo 1 through a sealing bearing, one end of the vertical shaft 3 is fixedly connected to the output shaft of the motor 4, the output shaft of the motor 4, the vertical shaft 3, and the silo 1 are coaxially arranged, the motor 4 is fixedly installed on the silo 1, a spiral blade 5 is fixedly installed on the vertical shaft 3, and the spiral blade 5 is coaxially arranged with the vertical shaft 3, and a plurality of rotating rings 6 with different diameters are arranged in the silo 1, and the rotating ring 6 is coaxially arranged with the vertical shaft 3, and the plurality of rotating rings 6 are in At the same horizontal height and coaxially arranged, two adjacent rotating rings 6 are rotatably connected through bearings, the innermost rotating ring 6 is fixedly connected to the vertical axis 3, and the outermost rotating ring 6 is rotatably connected to the inner wall of the silo 1 through bearings. Several stirring rods 7 are fixedly installed on the rotating rings 6. Except for the innermost rotating ring 6, the remaining rotating rings 6 are respectively provided with annular grooves 8. The bottom surface of the annular groove 8 is a circle of spirals, and the height of the bottom surface gradually decreases from one end to the other end. The first spring telescopic rod 10 is respectively provided in the annular groove 8 for sliding contact and cooperation. The first spring telescopic rod 10 is transmission-connected with the rotating ring 6 adjacent to the inner side thereof. The present invention has a simple structure and an ingenious design. It can make the rotating ring 6 rotate in sequence and drive the corresponding stirring rod 7 to rotate, so that the stirring rod 7 scrapes the raw materials in the silo 1 from the middle to the outside in sequence, avoiding the problems of arching and drilling inclined holes in the raw materials, so that the raw materials can be discharged smoothly, which can meet actual needs and is suitable for promotion.When the silo 1 is discharging materials outward, the sealing cover 2 is opened, and the vertical shaft 3 and the rotating ring 6 and the spiral blade 5 thereon are driven by the motor 4 to rotate forwardly. Since the silo 1 is full of raw materials, the friction between the raw materials and the stirring rod 7 is greater than the friction between the first spring telescopic rod 10 and the annular groove 8. At this time, the rotating ring 6 on the vertical shaft 3, that is, the rotating ring 6 of the first circle will not drive the rotating ring 6 of the second circle adjacent to it to rotate, and the other rotating rings 6 will not rotate either, and the stirring rod 7 will not be driven. At this time, the rotating ring 6 on the vertical shaft 3 drives the first spring telescopic rod 10 connected to it to revolve, so that it moves in the annular groove 8 of the second circle and moves along the spiral ascending direction of the bottom surface of the annular groove 8. The movement of the first spring telescopic rod 10 The first end of the silo 1 is lifted, the first spring telescopic rod 10 is compressed, the pressure on the bottom surface of the annular groove 8 is increased, and then the friction force is increased, until the first spring telescopic rod 10 rotates one circle in the annular groove 8, and then moves from the highest point of the bottom surface of the annular groove 8 to the lowest point, the first spring telescopic rod 10 is extended, and rotates one circle along the bottom surface of the annular groove 8 again, the rotation of the spiral blade 5 will first transport the raw materials in the middle part of the silo 1 downward, and finally discharge it, thereby avoiding the arching of the raw materials and the accumulation in the silo 1. After the raw materials in the middle of the silo 1 are reduced, the friction of the raw materials here on the stirring rod 7 on the second circle of the rotating ring 6 is reduced. When the friction of the stirring rod 7 is less than the friction between the first spring telescopic rod 10 and the annular groove 8, the first circle The first spring telescopic rod 10, which is transmission-connected to the rotating ring 6, drives the rotating ring 6 of the second circle to rotate together by virtue of the friction between the first spring telescopic rod 10 and the annular groove 8, thereby driving the stirring rod 7 on the rotating ring 6 of the second circle to rotate together, and the corresponding raw materials in the silo 1 are also scraped off and discharged smoothly. Here, the friction of the material on the stirring rod 7 on the rotating ring 6 of the third circle is reduced, and then, in the same principle as the above process, the first spring telescopic rod 10, which is transmission-connected to the rotating ring 6 of the second circle, drives the rotating ring 6 of the third circle to rotate, thereby driving the stirring rod 7 thereon to rotate together, and so on, the stirring on the rotating rings 6 of the remaining circles will be driven one by one, and the raw materials at different positions in the silo 1 will be scraped off in turn, so that the raw materials can be discharged smoothly. When the motor 4 drives the rotating ring 6 of the second circle, the stirring rod 7 on the third circle is driven to rotate. When the movable vertical shaft 3 rotates in the opposite direction, the vertical shaft 3 drives the rotating ring 6 of the first circle to rotate, and drives the corresponding first spring telescopic rod 10 to move in the annular groove 8. When the first spring telescopic rod 10 moves to the intersection of the highest point and the lowest point at both ends of the bottom surface of the annular groove 8, it is blocked by the height difference and cannot continue to move, thereby driving the rotating ring 6 of the second circle to rotate. Based on the same principle, the rotation of the rotating ring 6 of the second circle will also drive the rotating ring 6 of the third circle to rotate, until all the rotating rings 6 rotate together, thereby driving all the stirring rods 7 to overcome the friction of the material and rotate, stirring the raw materials in the silo 1 to prevent the material from sedimentation and separation. At the same time, the spiral blades 5 lift the raw materials upward, thereby further increasing the mixing and stirring effect.

[0019] Specifically, if Figure 1As shown, in this embodiment, the first spring telescopic rod 10 is respectively connected to the inner gear ring 20, and the inner gear ring 20 is rotatably mounted on the rotating ring 6 where the corresponding first spring telescopic rod 10 is located through a bearing, and the inner gear ring 20 is coaxially arranged with the vertical axis 3, and the inner side of the inner gear ring 20 is respectively meshed with a circle of several transmission gears 21, and the transmission gears 21 of the same circle are evenly distributed circumferentially, and the transmission gears 21 are rotatably mounted in the silo 1, and the transmission gears 21 are rotatably connected to the coaxial support column 22 through a bearing, and the support column 22 is fixedly mounted on the inner wall of the silo 1, and one side of the transmission gears 21 of the same circle is meshed with the same outer gear ring 23, and the outer gear ring 23 is fixedly mounted on the corresponding first spring telescopic rod 10 The adjacent rotating ring 6, the spiral directions of the bottom surfaces of the annular grooves 8 on the adjacent rotating rings 6 are opposite. When one rotating ring 6 rotates, it will drive the outer gear ring 23 on it to rotate together. The rotation of the outer gear ring 23 is driven by the corresponding transmission gear 21, thereby driving the inner gear ring 20 connected to it to rotate in the opposite direction. The inner gear ring 20 then drives the first spring telescopic rod 10 to rotate together. The first spring telescopic rod 10 can drive the rotating ring 6 on it to rotate through friction, thereby realizing the rotation of two adjacent rotating rings 6 in opposite directions. The rotation of the remaining adjacent rotating rings 6 is similar. When the rotating ring 6 rotates, it will drive the stirring rod 7 on it to revolve, and the rotation directions of the stirring rods 7 on adjacent rotating rings 6 are also opposite, so that the material in the silo 1 can be stirred better and more evenly.

[0020] Specifically, Figure 1 , Figure 8 As shown, the inner gear ring 20 of the present embodiment is provided with through holes 30 corresponding to the first spring telescopic rod 10, and the first spring telescopic rod 10 is slidably installed in the corresponding through holes 30. One end of the first spring telescopic rod 10 is fixedly connected to the inner ring of the second bearing, and the outer ring of the second bearing is rotatably connected to the threaded rod 31 through the third bearing. The second bearing is coaxially arranged with the vertical axis 3, and the third bearing is coaxially arranged with the corresponding threaded rod 31. The silo 1 is provided with a threaded hole 32 corresponding to the threaded rod 31, and the threaded rod 31 is threadedly installed in the corresponding threaded hole 32. By rotating the threaded rod 31, the corresponding third bearing, the second bearing, and the first spring telescopic rod 10 can be driven to move upward or downward. When the first spring telescopic rod 10 moves downward, the first spring telescopic rod 10 is shortened, so that the pressure of the first spring telescopic rod 10 on the bottom surface of the annular groove 8 increases, thereby increasing the friction with the annular groove 8, and vice versa, the friction with the annular groove 8 is reduced, so that the friction between the first spring telescopic rod 10 and the annular groove 8 can be adjusted according to demand.

[0021] Further, such as Figure 1 As shown, in this embodiment, coaxial hand wheels 40 are respectively fixedly mounted on the threaded rods 31. Rotating the threaded rods 31 by the hand wheels 40 is more convenient and labor-saving.

[0022] Furthermore, Figure 1 As shown, the stirring rod 7 on the outermost side of this embodiment is matched with the inner wall gap of the silo 1, and the scraper rod 50 is fixedly installed, and the scraper rod 50 is matched with the inner wall gap of the bottom of the silo 1. The stirring rod 7 and the scraper rod 50 are matched with the inner wall gap of the silo 1, so that when they revolve, they can scrape the materials on the inner wall to avoid the materials sticking to the inner wall.

[0023] Furthermore, Figure 1 , Figure 6 , Figure 7As shown, the lower end of the vertical axis 3 described in this embodiment is provided with a cavity connected to the outside, and a coaxial spiral groove 60 is provided on the inner wall of the cavity, and circular grooves 61 are respectively provided at both ends of the spiral groove 60, and a slider 62 is slidably installed in the circular groove 61 on the upper side, and the slider 62 can slide in the spiral groove 60, and a vertical rod 63 is fixedly installed on the slider 62, and the vertical rod 63 is coaxially arranged with the vertical axis 3, and the vertical rod 63 is fixedly connected to the sealing cover 2, and one side of the sealing cover 2 is fixedly connected to one end of the second spring telescopic rod 64, and the other end of the second spring telescopic rod 64 is fixedly connected to the silo 1. When the vertical shaft 3 rotates forward, the slider 62 slides relative to the circular groove 61 on the upper side. When the slider 62 slides to the upper end of the spiral groove 60, the second spring telescopic rod 64 is compressed here. The second spring telescopic rod 64 extends by elastic force and pulls the sealing cover 2, the vertical rod 63 and the slider 62 downward, so that the slider 62 moves into the spiral groove 60. The vertical shaft 3 continues to rotate, so that the slider 62 continues to move downward under the guidance of the spiral groove 60, thereby driving the vertical rod 63. , the sealing cover 2 moves downward until the slider 62 moves into the lower end of the spiral chute 60, and then moves into the circular groove 61 on the lower side. At this time, the vertical shaft 3 rotates, causing the slider 62 to slide relatively in the circular groove 61 on the lower side. At this time, the second spring telescopic rod 64 is stretched. Since the spiral chute 60 exerts a downward force on the slider 62 when the vertical shaft 3 rotates forward, the slider 62 cannot rely on the force of the second spring telescopic rod 64. The slider 62 slides relative to the circular groove 61 on the lower side, and the silo 1 The bottom of the material is completely opened to facilitate material discharge; the vertical shaft 3 rotates in the opposite direction to drive the circular groove 61 and the spiral chute 60 to rotate. When the lower end of the spiral chute 60 is aligned with the slider 62, since the second spring telescopic rod 64 is in a stretched state at this time, the second spring telescopic rod 64 drives the sealing cover 2, the vertical rod 63, and the slider 62 to move upward, so that the slider 62 enters the spiral chute 60, and the spiral chute 60 rotates in the opposite direction, giving the slider 62 an upward lifting force, so that the slider 62 continues to move upward until the slider 62 passes the upper end of the spiral chute 60 and moves into the circular groove 61 on the upper side. At this time, the sealing cover 2 closes the silo 1, and the second spring telescopic rod 64 is in a compressed state, giving the slider 62 a downward pulling force, but the lifting force given to the slider 62 by the reverse rotation of the spiral chute 60 will prevent it from moving downward, thereby maintaining the slider 62 in the circular groove 61 on the upper side, and under the reverse rotation of the vertical shaft 3, the slider 62 slides relative to the circular groove 61, and the sealing cover 2 remains sealed.

[0024] Furthermore, if Figure 1As shown, in this embodiment, the left and right sides of the second bearing are rotatably connected to the threaded rod 31 through the third bearing, the outer ring of the third bearing is fixedly connected to the outer ring of the second bearing, and the inner ring of the third bearing is fixedly connected to the threaded rod 31, and the threaded rod 31 is threadedly mounted on the silo 1. Connecting the threaded rod 31 on the left and right sides of the second bearing can make the second bearing and the first spring telescopic rod 10 more balanced, which is conducive to maintaining balance.

[0025] Furthermore, Figure 1 As shown, the bottom opening of the silo 1 in this embodiment is fixedly installed with a rubber ring 70, and the sealing cover 2 fits the rubber ring 70. The rubber ring 70 can increase the sealing performance between the sealing cover 2 and the silo 1 to prevent material leakage.

[0026] Furthermore, Figure 1 , Figure 4 , Figure 5 , Figure 8 As shown, in this embodiment, the first spring telescopic rod 10 is rotatably connected to the roller 9, the roller 9 is installed on the movable end of the first spring telescopic rod 10, and the fixed end of the first spring telescopic rod 10 is slidably installed in the through hole 30 and fixedly connected to the inner ring of the second bearing. The roller 9 can convert sliding friction into rolling friction, so that the first spring telescopic rod 10 moves more smoothly.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
