DETAILED DESCRIPTION

[0026] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0027] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached Figure 1 The layout is described in detail, such as the positional relationship of front, back, top, bottom, left, right, etc., which is based on the attached manual. Figure 1 It is determined by the layout direction.

[0028] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1: As shown in the attached Figures 1 to 10 As shown, the dual-drive bucket rotary distributor device includes a support frame 1, a rotating frame, a hopper 2, a valve plate 5, a limiting mechanism, a driving mechanism, a discharging mechanism and a resetting mechanism. An annular rotating frame is rotatably installed on the upper side of the support frame 1, and a plurality of hoppers 2 are evenly spaced along the circumference of the rotating frame. A discharge port 3 that passes through the upper and lower sides of the hopper 2 is provided on the lower side of the hopper 2. A hinge shaft 4 is fixedly installed on the lower side of the hopper 2. The central axis of the hinge shaft 4 is perpendicular to the movement direction of the corresponding hopper 2. A valve plate 5 that can open and close the discharge port 3 is rotatably installed on the outer side of the hinge shaft 4. A limiting mechanism is provided on the outer side of the rotating frame corresponding to each position of the hopper 2, and a valve plate 5 that can open and close the discharge port 3 is provided on the limiting mechanism. The support frame 1 is provided with a discharge mechanism and a driving mechanism that can rotate the rotating frame on the upper side of the support frame 1; along the rotation direction of the hopper 2, a reset mechanism that can lift the valve plate 5 upward after swinging is provided in the support frame 1 in front of the discharge mechanism; when the lower side of the limiting mechanism abuts against the upper side of the discharge mechanism after the rotating frame rotates, the end of the valve plate 5 away from the hinge shaft 4 is separated from the groove 6 to open the discharge port 3; and before the valve plate 5 passes through the reset mechanism, the limiting mechanism and the discharge mechanism are separated from each other, so that the end of the valve plate 5 away from the hinge shaft 4 is clamped in the groove 6 again.

[0029] When in use, the support frame 1 is fixed on the top of the feed bin, and the discharge mechanism is set at the entrance of the feed bin. When the driving mechanism works, the rotating frame is driven to rotate on the upper side of the support frame 1, and the hopper 2 filled with materials rotates with the rotating frame. Before reaching the discharge mechanism, the slot 6 of the locking arm 11 supports the end of the valve plate 5 away from the hinge shaft 4, so that the locking arm 11 and the hinge shaft 4 jointly fix the valve plate 5 and the hopper 2 together, so that the valve plate 5 closes the discharge port 3. When the hopper 2 filled with materials continues to rotate with the rotating frame to the position of the discharge mechanism, the lower side of the limiting mechanism moves from the upper side of the discharge mechanism, so that the locking arm 11 slowly swings and gradually contacts the end of the valve plate 5 away from the hinge shaft 4. Separated from each other, when the lower end of the limiting mechanism passes through the upper end of the discharge mechanism, the limiting mechanism operates to make the valve plate 5 open the discharge port 3 under the weight of the material in the hopper 2 and its own gravity, and the material in the hopper 2 falls into the feed bin through the discharge port 3. The emptied hopper 2 continues to rotate with the rotating frame, and when the valve plate 5 rotates to the reset mechanism and passes through the upper side of the reset mechanism, the reset mechanism lifts the valve plate 5 to the initial position. At this time, the limiting mechanism and the discharge mechanism are separated from each other and reset to the initial position, so that the end of the valve plate 5 away from the hinge shaft 4 is again stuck in the card slot 6 and closes the discharge port 3, so that the hopper 2 can continue to load after rotating, and the feed bin can be continuously fed in this way. The structure of the present invention is reasonable and compact, and the discharge mechanism can be installed on the outside of the support frame 1 according to the position of the feed bin entrance. It is convenient to install and adjust, and it is also convenient for subsequent maintenance, which simplifies the maintenance process, shortens the downtime, and can also improve the stability during use.

[0030] The above-mentioned dual-drive bucket rotary distributor device can be further optimized and / or improved according to actual needs: Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figures 1 to 10As shown, the rotating frame includes an inner fixed ring plate 7 and an outer fixed ring plate 8 which are arranged above the support frame 1 from the inside to the outside, and the hopper 2 is fixedly installed between the outer side of the inner fixed ring plate 7 and the inner side of the outer fixed ring plate 8 along the circumference. The lower ends of the inner fixed ring plate 7 and the lower ends of the outer fixed ring plate 8 are evenly distributed with a plurality of steel wheels 9 along the circumference. The limiting mechanism includes a rotating shaft 10, a locking arm 11 and a connecting arm 12. The side of the hopper 2 away from the hinge shaft 4 is rotatably installed with a rotating shaft 10 whose end is located outside the outer fixed ring plate 8, and at least one locking arm 11 is fixedly installed at intervals on the outer side of the middle part of the rotating shaft 10, and each locking arm 11 is provided with an opening The upward slot 6 is fixedly installed with the outer side of the end of the rotating shaft 10 corresponding to the outer side of the outer fixed ring plate 8 and one end of the laterally arranged connecting arm 12, and the connecting arm 12 makes the lower inner wall of the slot 6 press against the lower side of the valve plate 5, and the lower side of the connecting arm 12 moves from the upper side of the discharge mechanism as the outer fixed ring plate 8 rotates. After the rotating shaft 10 rotates and makes the end of the valve plate 5 away from the hinge shaft 4 separate from the slot 6, the discharge port 3 is opened, and before the valve plate 5 passes through the reset mechanism, the lower side of the connecting arm 12 is separated from the upper side of the discharge mechanism, so that the end of the valve plate 5 away from the hinge shaft 4 is again clamped in the slot 6.

[0031] According to the demand, the driving mechanism drives the outer fixed ring plate 8 to rotate, thereby driving the hopper 2 and the inner fixed ring plate 7 to rotate on the upper side of the support frame 1. During use, by setting the steel wheel 9, the wear of the inner fixed ring plate 7 and the outer fixed ring plate 8 when they rotate on the upper side of the support frame 1 can be reduced, and the installation between the rotating frame and the support frame 1 is also convenient. In order to facilitate the installation of the limit mechanism, the limit mechanism can be set on the outer side of the lower part of the hopper 2. In a specific embodiment, the hopper 2 located at the frontmost position has two articulated sleeves fixedly installed at intervals at the front and rear right sides of the lower part of the hopper 2. The front and rear ends of the articulated shaft 4 are rotatably installed in the articulated sleeves at the corresponding positions respectively. A fixed sleeve is fixedly installed on the outer side of the middle part of the articulated shaft 4. The outer side of the lower part of the fixed sleeve is fixedly installed together with the upper side of the right part of the valve plate 5. The rotating shaft 10 is arranged on the left side of the lower part of the hopper 2 along the front-to-back direction, and two connecting ear plates are rotatably installed on the outer side of the rotating shaft 10 at intervals in front and back. The right parts of the connecting ear plates are fixedly installed with the front side and the rear side of the lower part of the hopper 2 respectively, and two L-shaped locking arms 11 are fixedly installed between the connecting ear plates at intervals in front and back. The notch on the right part of the locking arm 11 forms a card slot 6. After the upper side of the right part of the locking arm 11 abuts against the lower side of the left part of the valve plate 5, the upper side of the valve plate 5 is in sealing contact with the discharge port 3 of the hopper 2, so that the valve plate 5 closes the discharge port 3, and the front end of the rotating shaft 10 is located in front of the outer fixed ring plate 8, and the right end of the connecting arm 12 is fixedly installed with the outer side of the front part of the rotating shaft 10.

[0032] Embodiment 3: As an optimization of the above embodiment, as shown in the attached Figure 1 , 3As shown in Figure 8, the limiting mechanism also includes a counterweight block 13, a swing arm 14 and a limit pin 15. A vertically arranged swing arm 14 is fixedly installed on the outer side of the end of the rotating shaft 10 corresponding to the outer side of the outer fixed ring plate 8, one end of the connecting arm 12 is fixedly installed together with the upper part of the swing arm 14, and the other end of the connecting arm 12 is detachably fixedly installed with the counterweight block 13. A limit pin 15 parallel to the rotating shaft 10 is fixedly installed on the outer side of the lower part of the outer fixed ring plate 8 corresponding to the upper part of the rotating shaft 10. A limit groove 16 which runs through the front and back and matches the limit pin 15 is provided on the upper part of the swing arm 14, and the limit pin 15 is located in the limit groove 16.

[0033] According to the needs, the lower side of the swing arm 14 rotates with the outer fixed ring plate 8 and moves from the upper side of the discharge mechanism. The rotating shaft 10 rotates so that the end of the valve plate 5 away from the hinge shaft 4 is separated from the slot 6 and then the discharge port 3 is opened. When the valve plate 5 passes through the reset mechanism, the end of the valve plate 5 away from the hinge shaft 4 is again clamped in the slot 6. A mounting screw is fixedly installed on the front side of the left end of the connecting arm 12 located in the front. The counterweight 13 is circular, and a mounting through hole is provided at the front end of the counterweight 13, which passes through the mounting through hole and is screwed with a mounting nut. This facilitates the installation of the counterweight 13 and the combination of multiple counterweights 13, and is convenient for disassembly, assembly and maintenance. The limit groove 16 is provided on the upper left side of the swing arm 14, and the limit groove 16 is in an arc shape with an opening to the left.

[0034] After the hopper 2 passes through the discharging mechanism, the discharging port 3 is closed after the discharging port 3 is opened.

[0035] In order to reduce the torque exerted by the counterweight 13 on the rotating shaft 10 when the rotating shaft 10 returns to its initial position, a limit groove 16 is provided on the upper part of the swing arm 14 and a limit pin 15 fixedly installed with the outer fixed ring plate 8 is provided in the limit groove 16, so that the limit pin 15 can limit and support the swing arm 14 and balance the torque applied to the rotating shaft 10. In order to prevent the swing arm 14 from interfering with the maintenance position, the upper side of the swing arm 14 can be tilted forward or backward along the rotation direction of the hopper 2, and a limit groove 16 is provided on the upper part of the swing arm 14 and a limit pin 15 is fixedly installed at the corresponding position of the outer fixed ring plate 8.

[0036] Embodiment 4: As an optimization of the above embodiment, as shown in the attached Figure 1 , 3 As shown in Figures 5 and 7, the discharge mechanism includes a discharge base 17 and a discharge plate. The discharge base 17 is fixedly installed on the front side of the lower part of the support frame 1, and the discharge plate is installed on the upper side of the discharge base 17. The discharge plate includes an inclined section 18 and a horizontal section 19 which are connected together in sequence along the rotation direction of the hopper 2, and the distance between the upper side of the inclined section 18 and the lower end of the outer fixed ring plate 8 gradually decreases. The reset mechanism includes a reset frame 20, a reset wheel 21 and an elastic reset member 22. Along the rotation direction of the hopper 2, the reset frame 20 is arranged in the support frame 1 in front of the discharge base 17, and the reset wheel 21 is rotatably installed on the upper side of the reset frame 20. An elastic reset member 22 is provided between the lower side of the reset frame 20 and the inner side of the support frame 1. The valve plate 5 rotates to the upper side of the reset wheel 21 and is lifted up by the reset wheel 21. At the same time, the lower side of the swing arm 14 is separated from the horizontal section 19 and reset so that the end of the valve plate 5 away from the hinge shaft 4 is clamped in the clamping groove 6 again.

[0037] According to the requirements, the elastic reset member 22 is an existing well-known technology, such as a compression spring. In order to prevent the reset frame 20 from swinging during use, two guide sleeves are fixedly installed at intervals on the lower side of the reset frame 20, and each guide sleeve is provided with a guide column whose lower end is fixedly installed together with the lower part of the support frame 1. The reset mechanism can also be an existing well-known tension spring. One end of the tension spring is fixedly installed on the outside of the outer fixed ring plate 8 above the counterweight block 13, and the other end of the tension spring is fixedly connected to the swing arm 14 above the rotating shaft 10. In this way, after the swing arm 14 is separated from the upper side of the horizontal section 19 of the discharge plate, the tension spring is reset, pulling the upper end of the swing arm 14 to the initial position, and the connection between the inclined section 18 and the horizontal section 19 is smoothly transitioned.

[0038] During use, the driving mechanism drives the outer fixed ring plate 8 and the inner fixed ring plate 7 to rotate on the upper side of the support frame 1 when working, so that the hopper 2 fixedly installed between the inner fixed ring plate 7 and the outer fixed ring plate 8 rotates along the central axis of the inner fixed ring plate 7. When the lower side of the swing arm 14 moves to the surface of the inclined section 18 of the discharge plate, the distance between the upper side of the inclined section 18 and the lower end of the outer fixed ring plate 8 gradually decreases, so that the surface of the inclined section 18 will generate resistance to the swing arm 14, so that the swing arm 14 The lower side swings in the direction opposite to the rotation direction of the hopper 2. After the lower side of the swing arm 14 swings, it drives the rotating shaft 10 and the locking arm 11 to swing. After the locking arm 11 swings, the L-shaped slot 6 with an opening upward on the locking arm 11 flips over, so that the inner wall of the slot 6 no longer supports the end of the valve plate 5 away from the hinge shaft 4. The valve plate 5 swings along the hinge shaft 4 under the action of the gravity of the material in the hopper 2 and the gravity of the valve plate 5 itself, thereby opening the discharge port 3, so that the material in the hopper 2 falls into the feed bin through the discharge port 3.

[0039] When the lower side of the swing arm 14 moves to the upper side of the horizontal section 19 of the discharge plate, all the materials in the hopper 2 fall into the feed bin. At this time, the lower side of the valve plate 5 contacts the outer side of the upper part of the reset wheel 21. Under the gravity of the material, the valve plate 5 presses down the reset wheel 21. After the reset wheel 21 moves downward, the elastic reset member 22 contracts and stores energy. After all the materials in the hopper 2 are emptied, the elastic reset member 22 resets to make the reset wheel 21 move upward. In this way, the impact between the reset wheel 21 and the valve plate 5 can be reduced, which plays a buffering role and prolongs the service life of the valve plate 5. As the valve plate 5 continues to rotate with the hopper 2, it swings upward under the action of the elastic reset member 22 and the reset wheel 21 to close the discharge port 3. When the reset wheel 21 is not completely separated from the valve plate 5, the lower side of the swing arm 14 slides over the upper side of the horizontal section 19 of the discharge plate and separates from the horizontal section 19. At this time, the rotating shaft 10 rotates under the action of the counterweight block 13, so that the locking arm 11 rotates and resets, so that the locking groove 6 of the locking arm 11 supports the end of the valve plate 5 away from the hinge shaft 4 after being reset, thereby achieving the closing effect of the valve plate 5 on the discharge port 3.

[0040] The setting of the reset wheel 21 can reduce the wear between the valve plate 5 and the reset wheel 21 when the valve plate 5 is closed, extend the service life, and reduce the impact when the valve plate 5 is closed, so that the closing of the valve plate 5 is smoother. The setting of the elastic reset member 22 is convenient for the installation of the reset frame 20 in the support frame 1, and the valve plate 5 can be rotated to the initial position before the swing arm 14 is separated from the upper side of the horizontal section 19 of the discharge plate. In this way, the swing arm 14 is also reset after being separated from the upper side of the horizontal section 19 of the discharge plate, which can support the valve plate 5, so that the valve plate 5 closes the discharge port 3.

[0041] Embodiment 5: As an optimization of the above embodiment, as shown in the attached Figure 1 , 3As shown in Figures 5 and 7, the discharge mechanism also includes a discharge cylinder 23, a first connecting rod 24 and a second connecting rod 25. The end of the inclined section 18 away from the horizontal section 19 is hingedly installed with the upper part of the discharge base 17, the first connecting rod 24 is hingedly installed on the lower side of the end of the horizontal section 19 close to the reset frame 20, the second connecting rod 25 is hingedly installed on the lower part of the discharge base 17, the middle part of the second connecting rod 25 is hingedly installed with the lower part of the first connecting rod 24, and the discharge cylinder 23 is hingedly installed between the upper part of the second connecting rod 25 and the discharge base 17.

[0042] According to the requirements, the discharge cylinder 23 is an existing well-known cylinder, such as the SC series Yadeke cylinder with magnetic adjustable stroke. The cylinder barrel of the discharge cylinder 23 is hingedly installed with the discharge base 17, and the piston rod of the discharge cylinder 23 is hingedly installed with the upper part of the second connecting rod 25. During use, by setting the discharge cylinder 23, when the piston rod of the discharge cylinder 23 is extended, the second connecting rod 25 drives the first connecting rod 24 to swing, and finally the horizontal section 19 of the discharge plate rises. When the piston rod of the discharge cylinder 23 is retracted, the second connecting rod 25 drives the first connecting rod 24 to swing in the opposite direction, and finally the horizontal section 19 of the discharge plate is lowered. In this way, the distance between the upper side of the horizontal section 19 and the lower end of the outer fixed ring plate 8 can be adjusted, so that all the lower sides of the swing arms 14 can smoothly open the discharge port 3 after passing through the upper side of the discharge plate, so that the material in the hopper 2 can smoothly fall into the feed bin, ensuring that the discharge port 3 is opened in time and accurately.

[0043] Embodiment 6: As an optimization of the above embodiment, as shown in the attached Figure 3 , 5 As shown in , 7 , a roller 26 is rotatably mounted on the lower side of the swing arm 14 , and the distance between the outer side of the lower end of the roller 26 and the lower end of the outer fixed ring plate 8 is greater than the distance between the upper side of the horizontal section 19 and the lower end of the outer fixed ring plate 8 .

[0044] According to the requirements, a groove with an opening downward is provided on the lower side of the swing arm 14, and the upper part of the roller 26 is rotatably installed in the groove. The central axis of the roller 26 is perpendicular to the movement direction of the swing arm 14. The lower side of the roller 26 is located below the lower side of the swing arm 14, and the lower side of the roller 26 is located below the outer fixed ring plate 8. The distance between the upper side of the horizontal section 19 and the lower end of the outer fixed ring plate 8 is smaller than the minimum distance between the upper side of the inclined section 18 and the lower end of the outer fixed ring plate 8.

[0045] During use, by setting the roller 26, the friction force when the lower side of the swing arm 14 and the upper side of the discharge plate contact each other can be reduced, thereby extending the service life. The distance between the outer side of the lower end of the roller 26 and the lower end of the outer fixed ring plate 8 is greater than the distance between the upper side of the horizontal section 19 and the lower end of the outer fixed ring plate 8. In this way, when the roller 26 rolls to the upper side of the inclined section 18, the inclined section 18 will generate resistance to the swing arm 14 through the roller 26, so that the lower side of the swing arm 14 swings in the opposite direction of the rotation of the hopper 2. In this way, the swing arm 14 drives the rotating shaft 10 and the locking arm 11 to rotate. After the locking arm 11 rotates, the slot 6 of the locking arm 11 no longer supports the valve plate 5. The valve plate 5 rotates under the action of its own gravity and the gravity of the material in the hopper 2, thereby opening the discharge port 3, and the material in the hopper 2 falls into the feed bin through the discharge port 3.

[0046] Embodiment 7: As an optimization of the above embodiment, as shown in the attached Figures 3 to 8 As shown, the locking arm 11 is L-shaped, sickle-shaped, crescent-shaped or hook-shaped.

[0047] According to the needs, in order to increase the contact area between the slot 6 of the locking arm 11 and the valve plate 5, the locking arm 11 is L-shaped, and two locking arms 11 are fixedly installed at intervals on the outer side of the middle part of the rotating shaft 10. The two locking arms 11 located on the lower side of the front hopper 2 are both L-shaped, and the slot 6 is formed on the right inner wall of the locking arm 11. The left side and the lower side of the locking arm 11 are both arc-shaped. This can avoid breakage at the left corner of the slot 6 and extend the service life of the locking arm 11.

[0048] Embodiment 8: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in Figures 9 and 10, the driving mechanism includes a driving base 27 and a reduction motor 28. At least two driving bases 27 are fixedly installed at intervals along the circumference on the outer side of the support frame 1, and a reduction motor 28 is fixedly installed on the upper side of each driving base 27. An upper mounting ring plate 29 and a lower mounting ring plate 30 are fixedly installed at intervals from top to bottom on the outer side of the middle part of the outer fixed ring plate 8. A number of connecting bolts 31 are evenly distributed along the circumference between the upper mounting ring plate 29 and the lower mounting ring plate 30. A rotating sleeve 33 is mounted on the outer side of the middle part of each connecting bolt 31, and tooth grooves 34 are formed between every two adjacent rotating sleeves 33. A driving sprocket 32 ​​meshing with the tooth grooves 34 is fixedly installed on the outer side of the lower end of the output shaft of each reduction motor 28.

[0049] According to the requirements, two driving bases 27 are evenly distributed along the circumference on the outside of the support frame 1, so that the force on the rotating frame can be more evenly distributed, avoiding the phenomenon that the rotating frame is separated from the support frame 1 after being offset during use. In order to increase the connection strength between the upper mounting ring plate 29 and the lower mounting ring plate 30 and the outer fixed ring plate 8, a number of reinforcing ribs are evenly distributed along the circumference on the upper side of the upper mounting ring plate 29 and the lower side of the lower mounting ring plate 30. No threads are set on the outer side of the connecting bolt 31 between the upper mounting ring plate 29 and the lower mounting ring plate 30. In order to reduce friction and impact, two bearings are set at upper and lower intervals between the inner side of the rotating sleeve 33 and the outer side of the connecting bolt 31, and the lower end of the connecting bolt 31 passes through the lower mounting ring plate 30 and is screwed with a fixing nut.

[0050] During use, a number of connecting bolts 31 are evenly spaced along the circumference between the upper mounting ring plate 29 and the lower mounting ring plate 30, and a rotating sleeve 33 is mounted on the outer side of the middle part of each connecting bolt 31, and each adjacent two rotating sleeves 33 form a tooth groove 34, and a driving sprocket 32 ​​meshing with the tooth groove 34 is fixedly mounted on the outer side of the lower end of the output shaft of each reduction motor 28, so that the meshing transmission between the driving sprocket 32 ​​and the rotating sleeve 33 is similar to the sprocket chain transmission effect, and the output shaft of the reduction motor 28 drives the outer fixed ring to rotate through the driving sprocket 32 ​​and the rotating sleeve 33. The setting of the rotating sleeve 33 makes the transmission more stable, which reduces the manufacturing cost and installation cost compared to the gear transmission, and can also simplify the maintenance process and shorten the downtime, thereby reducing the maintenance cost and increasing the enterprise benefit.

[0051] Embodiment 9: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in Figures 9 and 10, an outer rail 35 and an inner rail 36 are fixedly installed at intervals on the upper side of the support frame 1 from the inside to the outside. The outer rail 35 and the inner rail 36 are both in a circular shape. Several steel wheels 9 at the lower end of the inner fixed ring plate 7 are rollingly installed on the upper side of the inner rail 36, and several steel wheels 9 at the lower end of the outer fixed ring plate 8 are rollingly installed on the upper side of the outer rail 35.

[0052] According to the requirements, the outer steel rail 35 and the inner steel rail 36 have the same structure and are both existing well-known technologies. The several steel wheels 9 at the lower end of the inner fixed ring plate 7 are rotatably installed on the lower end of the inner fixed ring plate 7 through the existing well-known shaft seat, and the several steel wheels 9 at the lower end of the outer fixed ring plate 8 are rotatably installed on the lower end of the outer fixed ring plate 8 through the existing well-known shaft seat. The inner steel wheel 9 and the outer steel wheel 9 are independently arranged, which is convenient for the maintenance of the steel wheel 9 and can also increase the installation space of the limit mechanism to avoid affecting the switching of the valve plate 5.

[0053] The above technical features respectively constitute various embodiments of the present invention, which have strong adaptability and optimal implementation effects. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
