Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, this embodiment proposes a clearing device for a discharge hopper, including a discharge hopper body 1. A connecting pipe 2 is fixed to the bottom of the discharge hopper body 1. Four movable openings 3 are provided on the four sides of the bottom of the discharge hopper body 1. Each movable opening 3 has a connecting column 4, allowing the connecting column 4 to slide back and forth, thus facilitating the clearing of material in the discharge hopper body 1. A clearing rod 5 is fixedly connected to the inner end of the connecting column 4 by an internal hex bolt, facilitating assembly and disassembly. A set of clearing plates 6 are evenly fixed to both side walls of the clearing rod 5. The reciprocating movement of component 5 drives the unblocking plate 6 to reciprocate, thereby cleaning the material accumulating on the inner wall of the unloading bin body 1, facilitating unblocking of the unloading bin body 1 and ensuring smooth unloading. A reciprocating frame 7 is sleeved on the outer end of the connecting column 4, and a nut 8 is threaded onto the outer end of the connecting column 4. A connecting rod 9 is rotatably connected to the bottom end of the reciprocating frame 7, and a rotating rod 10 is rotatably connected to the bottom end of the connecting rod 9. A first rotating shaft 11 is fixed to the bottom end of the rotating rod 10, and the first rotating shaft 11 is rotatably connected to the unloading bin body 1. A first gear 12 is fixed on the first rotating shaft 11, and the lower side of the first gear 12 is... A second rotating shaft 13 is provided, and the second rotating shaft 13 is rotatably connected to the unloading bin body 1. A second gear 14, which meshes with the first gear 12, is fixedly connected to the second rotating shaft 13. The rotation of the second rotating shaft 13 causes the second gear 14 to rotate, which in turn drives the first gear 12 and the first rotating shaft 11 to rotate. The rotation of the first rotating shaft 11 causes the rotating rod 10 to rotate, thereby driving the connecting rod 9 to move, which in turn causes the reciprocating frame 7 to reciprocate, thus causing the unblocking rod 5 and the unblocking plate 6 to reciprocate, thereby facilitating the unblocking of the unloading bin body 1. Compared with the prior art, The efficiency of clearing blockages is higher, and it is less likely to cause early damage to the unloading hopper. A bearing plate 15 is fixedly connected to the connecting pipe 2. The bearing plate 15 is equipped with a linkage structure 16, which facilitates the simultaneous movement of the four clearing rods 5, reduces the time of the driving components, improves the clearing effect, and saves costs. The connecting pipe 2 is equipped with a stirring structure 17, which facilitates the stirring and crushing of the material at the bottom of the unloading hopper body 1, further improving the unloading effect. A discharge valve 18 is installed at the bottom of the connecting pipe 2. The discharge valve 18 is existing technology and will not be described in detail here. A conveying structure 19 is provided at the bottom of the discharge valve 18.

[0041] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, the linkage structure 16 further includes a gear ring 1601 disposed on the support plate 15. Four limiting sleeves 1602 are evenly slidably connected to the gear ring 1601. The four limiting sleeves 1602 are respectively fixedly connected to the support plate 15 by bolts. Four connecting shafts 1603 are evenly rotatably connected to the support plate 15. Each of the four connecting shafts 1603 has a fixedly connected drive gear 1604 that meshes with the gear ring 1601. A first universal joint 1605 is fixedly connected to the top of each connecting shaft 1603. A first connecting seat 1606 is rotatably connected to the first universal joint 1605. A transmission column 1607 is fixedly connected to the top of the first connecting seat 1606. A second connecting seat 1608 is fixedly connected to the top of the transmission column 1607. A second universal joint 1609 is rotatably connected inside the second connecting seat 1608, and the upper end of the second universal joint 1609 is fixed to the end of the second rotating shaft 13. The connection includes a drive bevel gear 1610 fixedly connected to the front connecting shaft 1603, and a mounting plate 1611 fixedly connected to the lower side of the right connecting shaft 1603. A first motor 1612 is fixedly connected to the mounting plate 1611, and the drive end of the first motor 1612 is fixedly connected to its bottom end near the connecting shaft 1603. The first motor 1612 causes the connecting shaft 1603 and the drive gear 1604 to rotate. The drive gear 1604 drives the gear ring 1601 to rotate, thereby driving the other drive gears 1604 and the connecting shaft 1603 to rotate. The rotation of the connecting shaft 1603 causes the first universal head 1605 to rotate, which in turn causes the first connecting seat 1606, the transmission column 1607, the second connecting seat 1608, and the second universal head 1609 to rotate, thereby causing the second rotating shaft 13 to rotate. This allows the four second rotating shafts 13 to rotate simultaneously, facilitating the simultaneous movement of the four unblocking rods 5 to unblock, thus improving the unblocking effect.

[0042] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, the agitation structure 17 further includes two assembly shafts 1701 symmetrically and rotatably arranged on the front side wall of the connecting pipe 2. A third gear 1702 is fixedly connected to the outer ends of both assembly shafts 1701, and an agitation rod 1703 is fixedly connected to the inner ends of both assembly shafts 1701. Two support seats 1704 are fixedly connected to the upper end surface of the bearing plate 15. A connecting rod 1705 is rotatably connected between the two support seats 1704. A fourth gear 1706, meshing with the third gear 1702, is fixedly connected to the inner end of the connecting rod 1705. The outer end of the connecting rod 1705... A driven bevel gear 1707 is fixedly connected to the driving bevel gear 1610 and meshes with it. The rotation of the driving bevel gear 1610 drives the driven bevel gear 1707 and the connecting rod 1705 to rotate. The rotation of the connecting rod 1705 drives the fourth gear 1706 to rotate, thereby causing the two third gears 1702 to rotate simultaneously. This, in turn, causes the assembly shaft 1701 and the stirring rod 1703 to rotate, thereby crushing the material at the bottom of the unloading hopper body 1, accelerating the falling of the material, and also crushing the caking material, further improving the unblocking effect. The linkage eliminates the need for a drive component and reduces costs.

[0043] like Figure 1 , Figure 7 and Figure 8 As shown, in a preferred embodiment, based on the above method, the material conveying structure 19 further includes a connecting hopper 1901 installed on the lower end face of the discharge valve 18. A feed pipe 1902 is sleeved at the bottom end of the connecting hopper 1901. A conveying cylinder 1903 is fixedly connected to the bottom end of the feed pipe 1902. A second motor 1904 is fixedly connected to one end of the conveying cylinder 1903. The drive end of the second motor 1904 passes through the conveying cylinder 1903 and is fixedly connected to a conveying shaft 1905. A spiral blade 1906 is fixedly connected to the conveying shaft 1905. A bearing seat 1907 is fixedly connected to the bottom of the connecting hopper 1901. The outer periphery of the feed pipe 1902... A gear ring 1908 is fixedly connected to the wall, and a servo motor 1909 is fixedly connected to the lower end face of the bearing seat 1907. The drive end of the servo motor 1909 is fixedly connected to a transmission gear 1910 that meshes with the gear ring 1908. The second motor 1904 drives the conveying shaft 1905 to rotate, thereby enabling the spiral blades 1906 to rotate, which facilitates the conveying of materials. The servo motor 1909 drives the transmission gear 1910 to rotate, which in turn drives the gear ring 1908 and the feed pipe 1902 to rotate, causing the conveying cylinder 1903 to rotate, which facilitates the adjustment of the conveying angle and provides greater flexibility.

[0044] like Figure 3As shown, in a preferred embodiment, based on the above method, the top of the unblocking rod 5 is provided with a leak-proof sleeve 20, which is fixedly connected to the unloading bin body 1 by bolts; this facilitates the reciprocating movement of the unblocking rod 5 and also prevents material leakage.

[0045] like Figure 3 As shown, in a preferred embodiment, based on the above method, two unblocking columns 21 are fixedly connected to each unblocking plate 6, and the length of the unblocking plate 6 decreases from top to bottom; this can improve the contact with the material and improve the unblocking effect.

[0046] like Figure 1 As shown, in a preferred embodiment, based on the above method, a support leg 22 is fixedly connected to the lower end face of the support plate 15, and a support foot 23 is fixedly connected to the bottom end of the support leg 22; this facilitates support, is simple to set up, and is convenient to use.

[0047] Specifically, when the unloading hopper uses the unblocking device, the following steps are taken: First, the first motor 1612 is started, causing its connected connecting shaft 1603 and drive gear 1604 to rotate. The drive gear 1604 causes the gear ring 1601 to rotate, thereby driving the remaining drive gears 1604 and connecting shaft 1603 to rotate. The rotation of the connecting shaft 1603 causes the first universal joint 1605 to rotate, which in turn causes the first connecting seat 1606, transmission column 1607, second connecting seat 1608, and second universal joint 1609 to rotate, thereby causing the second rotating shaft 13 to rotate. The rotation of the second rotating shaft 13 causes the second gear 14 to rotate, which in turn drives the first gear 12 and the first rotating shaft 11 to rotate. The rotation of the first rotating shaft 11 causes the rotating rod 10 to rotate, thereby driving the connecting rod 9 to move, which in turn causes the reciprocating frame 7 to reciprocate, thereby causing the unblocking rod 5 and unblocking plate 6 to reciprocate, thus clearing the blockage of material in the unloading hopper body 1; through the connecting shaft The rotation of 1603 drives the active bevel gear 1610 to rotate, which in turn drives the driven bevel gear 1707 and the connecting rod 1705 to rotate. The rotation of the connecting rod 1705 drives the fourth gear 1706 to rotate, thereby causing the two third gears 1702 to rotate simultaneously. This, in turn, causes the assembly shaft 1701 and the stirring rod 1703 to rotate, thus agitating and breaking up the material at the bottom of the unloading bin body 1, enhancing the unblocking effect. When material needs to be conveyed, the unloading valve 18 is opened to allow the material to flow into the conveying cylinder 1903. At the same time, the second motor 1904 is started to rotate the conveying shaft 1905 and the spiral blade 1906, thereby evenly conveying the material. If the feeding angle needs to be adjusted, the servo motor 1909 is started to rotate the transmission gear 1910. The transmission gear 1910 drives the gear ring 1908 and the feed pipe 1902 to rotate, thereby rotating the conveying cylinder 1903, facilitating flexible adjustment of the feeding angle.

[0048] All technical features in this embodiment can be freely combined according to actual needs.

[0049] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.

10. A method for unclogging a hopper unclogging device according to any one of claims 1-9, characterized in that, Includes the following steps: S1: When unblocking is required, the first motor (1612) is started, causing its connected connecting shaft (1603) and drive gear (1604) to rotate. The drive gear (1604) causes the gear ring (1601) to rotate, thereby driving the remaining drive gears (1604) and connecting shaft (1603) to rotate. The rotation of the connecting shaft (1603) causes the first universal joint (1605) to rotate, which in turn causes the first connecting seat (1606), transmission column (1607), second connecting seat (1608), and second universal joint (1605) to rotate. 609) rotates, thereby causing the second shaft (13) to rotate. The rotation of the second shaft (13) causes the second gear (14) to rotate. The second gear (14) drives the first gear (12) and the first shaft (11) to rotate. The rotation of the first shaft (11) causes the rotating rod (10) to rotate, thereby driving the connecting rod (9) to move. This causes the reciprocating frame (7) to reciprocate, thereby causing the unblocking rod (5) and the unblocking plate (6) to reciprocate, thereby clearing the blocked material in the unloading bin body (1). S2: In step one, the rotation of the connecting shaft (1603) drives the active bevel gear (1610) to rotate. The rotation of the active bevel gear (1610) drives the driven bevel gear (1707) and the connecting rod (1705) to rotate. The rotation of the connecting rod (1705) drives the fourth gear (1706) to rotate, thereby causing the two third gears (1702) to rotate simultaneously, which in turn causes the assembly shaft (1701) and the stirring rod (1703) to rotate, thereby stirring and breaking up the material at the bottom of the unloading bin body (1) and enhancing the unblocking effect. S3: When materials need to be conveyed, open the discharge valve (18) to allow the materials to flow into the conveying cylinder (1903). At the same time, start the second motor (1904) to make the conveying shaft (1905) and the spiral blade (1906) rotate, so as to deliver the materials evenly. If the feeding angle needs to be adjusted, start the servo motor (1909) to make the transmission gear (1910) rotate. The transmission gear (1910) drives the gear ring (1908) and the feed pipe (1902) to rotate, so as to make the conveying cylinder (1903) rotate, which facilitates the flexible adjustment of the feeding angle.
