[0019] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] Example 1, as Figures 1-6 As shown, according to an embodiment of the present application, a green refractory material automatic feeding mechanism includes two groups of double-axis conveying mechanisms 1, which are arranged side by side and symmetrically. A spacing adjustment component 3 is provided on the bottom side of the two groups of double-axis conveying mechanisms 1, and the spacing adjustment component 3 causes the radial spacing between the two groups of double-axis conveying mechanisms 1 to change; a gap shielding component 4 and a double-cylinder sealing component 5 are provided between the two groups of double-axis conveying mechanisms 1, and the gap shielding component 4 and the double-cylinder sealing component 5 always maintain the sealing between the two groups of double-axis conveying mechanisms 1 when the spacing between the two groups of double-axis conveying mechanisms 1 changes.

[0022] like Figure 1-Figure 3As shown, the double-axis conveying mechanism 1 includes a conveying cylinder 11, a conveying blade 12 and a conveying motor 13. The radial cross-section of the conveying cylinder 11 is an incomplete circle. The conveying blade 12 is coaxially arranged on the conveying cylinder 11. The conveying motor 13 is fixed to the end of the conveying cylinder 11 and is transmission-connected to the conveying blade 12. Specifically, a transmission shaft is provided at the axis of the conveying blade 12 and is keyed to the output shaft of the conveying motor 13. Thus, two groups of symmetrically arranged double-axis conveying mechanisms 1 constitute a double-axis auger, which is used to convey and load refractory materials.

[0023] Among them, a support assembly 2 is provided on the bottom side of the dual-axis conveying mechanism 1, and the support assembly 2 includes a fixed seat 21. Two displacement seats 22 are symmetrically provided on both sides of the fixed seat 21. The two conveying cylinders 11 and the two conveying motors 13 are symmetrically fixed to the two displacement seats 22 respectively. It can be understood that the two dual-axis conveying mechanisms 1 follow the two displacement seats 22 to move synchronously in the same direction.

[0024] It should be noted that the spacing adjustment assembly 3 includes an adjusting motor 31, a double-headed screw 32 and two guide rods 33. The adjusting motor 31 is fixed to the fixed seat 21, and the double-headed screw 32 rotates through the fixed seat 21 and is keyed to the output shaft of the adjusting motor 31. The two guide rods 33 are respectively fixed to the fixed seat 21 and slide through the two displacement seats 22. Specifically, the guide rods 33 are fixed through the fixed seat 21 along the width direction, and then slidingly connected to the two displacement seats 22 respectively. It can be understood that the adjusting motor 31 drives the double-headed screw 32 to rotate, which will force the two displacement seats 22 to undergo synchronous and opposite displacements on both sides of the fixed seat 21. The guide rods 33 play the role of rotation restriction and direction guidance. Furthermore, the displacement of the displacement seats 22 will synchronously drive the spacing changes of the dual-axis conveying mechanisms 1 fixed above them.

[0025] like Figures 1-4 As shown, the gap shielding assembly 4 includes a positioning frame 41, a fixed plate 42 and two groups of displacement plates 43. The positioning frame 41 is fixed to the fixed seat 21 and is located on the circumferential side of the two conveying cylinders 11. The fixed plate 42 is fixed to the positioning frame 41 and is located in the middle of the two conveying cylinders 11. The two groups of displacement plates 43 are symmetrically fixed to the two conveying cylinders 11 and are sealed and slidably inserted into the fixed plate 42.

[0026] It should be noted that in the specific embodiment of the present application, the fixed plate 42 and the displacement plates 43 slidingly inserted on both sides thereof are respectively arranged at the front and rear ends and the top side of the two conveying cylinders 11 to prevent the formation of gaps when radial displacement changes occur between the two conveying cylinders 11.

[0027] like Figure 5 and Figure 6As shown, the double-cylinder sealing assembly 5 is axially arranged on the bottom side of the two groups of double-axis conveying mechanisms 1, including a top arc plate 51, a bottom arc plate 52, a bearing seat 53 and two abutment plates 54. The top arc plate 51 is sealed and clamped on the inner bottom side of the two groups of double-axis conveying mechanisms 1, the bottom arc plate 52 is arranged on the bottom side of the two groups of double-axis conveying mechanisms 1 and is connected to the top arc plate 51, the bearing seat 53 is arranged on the bottom side of the bottom arc plate 52 and is elastically connected to the bottom arc plate 52, and the two abutment plates 54 are symmetrically fixed on the outer shell of the two groups of double-axis conveying mechanisms 1 and abut against the bottom arc plate 52.

[0028] It should be noted that the top arc plate 51 and the bottom arc plate 52 are both arranged in an axially symmetrical arc structure, and the upper end surface of the symmetrical arc structure is bent downward on both sides and arched in the middle. Among them, the top arc plate 51 has elastic deformation ability, that is, when the two conveying cylinders 11 approach each other, the top arc plate 51 is stretched to both sides, and its height decreases (that is, the angle of the lower end surface of the top arc plate 51 becomes larger); when the two conveying cylinders 11 move away from each other, the top arc plate 51 is squeezed toward the middle, and its height becomes higher (that is, the angle of the lower end surface of the top arc plate 51 becomes smaller).

[0029] It should be further explained that the top arc-shaped plate 51 is located on the inner bottom side of the two conveying cylinders 11 and is sealed against the inner wall of the conveying cylinder 11. Combined with its own elastic deformation ability, it ensures that no matter whether the distance between the two conveying cylinders 11 increases or decreases, the bottom position between the two conveying cylinders 11 will be sealed (that is, a complete bottom is formed between the two conveying cavities to prevent material leakage).

[0030] Among them, the top arc plate 51 is evenly inserted with multiple connecting screws 511 along the axial direction, and a sealing ring 512 is provided between the multiple connecting screws 511 and the top arc plate 51. The connecting screws 511 slide through the top arc plate 51 and are threadedly connected to the bottom arc plate 52.

[0031] It is understood that the top arc plate 51 is connected to the bottom arc plate 52 by the connecting screw 511, as shown in FIG. Figure 5 As shown, the top curved plate 51 and the bottom curved plate 52 form a pagoda shape.

[0032] Furthermore, the supporting seat 53 is evenly fixed with multiple sliding rods 531 along the length direction, and the multiple sliding rods 531 are slidably inserted into the bottom arc plate 52. A return spring 532 is sleeved on the sliding rod 531, and the two ends of the return spring 532 respectively abut against the supporting seat 53 and the bottom arc plate 52, so that an elastic connection is formed between the bottom arc plate 52 and the supporting seat 53. It should be noted that the multiple connecting screws 511 and the multiple sliding rods 531 are staggered to avoid interference between the two.

[0033] Preferably, the abutment plates 54 are symmetrically fixed to the bottom sides of the two conveying cylinders 11 and abut against the downward bend of the upper end surface of the bottom arc-shaped plate 52 .

[0034] In this way, it can be understood that when conveying and feeding different refractory materials, there is no need to replace the entire feeding equipment. According to the morphological characteristics of the refractory materials, the double-headed screw 32 is driven to rotate by adjusting the motor 31, so that the two displacement seats 22 move closer or farther away from the fixed seat 21, and then the two sets of dual-axis conveying mechanisms 1 move closer or farther away in the radial direction. In this way, it can be understood that the two conveying blades 12 will move closer or farther away in the radial direction, changing the spacing between the two conveying blades 12, and then making the feeding equipment adapt to the corresponding refractory materials. When the spacing between the two dual-axis conveying mechanisms 1 changes When the fixed plate 42 is fixed to the fixed seat 21 by the positioning frame 41, the fixed plate 42 will not move, and the displacement plates 43 on both sides thereof slide in the fixed plate 42 following the conveying cylinder 11. It can be understood that the sealing sliding arrangement between the displacement plate 43 and the fixed plate 42 keeps the two conveying cylinders 11 (except the bottom side) intact, avoiding the gap causing material leakage or dust escape, and the bottom sides of the two conveying cylinders 11 will also form a seal through the morphological change of the double-cylinder sealing component 5. Specifically, when the two conveying cylinders 11 approach each other, the abutment plate 54 moves from both sides to the middle and presses the bottom curved plate 52 The lower end surface of the bottom curved plate 52 is squeezed due to the curved design of the upper end surface of the bottom curved plate 52. When the abutment plate 54 moves toward the center, it will force the bottom curved plate 52 to move downward along the sliding rod 531 and squeeze the return spring 532. The bottom curved plate 52 is connected to the top curved plate 51 through the connecting screw 511. Then, at this time, the top curved plate 51 will move downward synchronously, and the two sides of the top curved plate 51 will move and slide relative to each other on the conveying cylinder 11. Because the top curved plate 51 is lowered as a whole, the two sides and the conveying cylinder 11 form a sealing abutment effect. Therefore, at this time, the angle of the lower end surface of the top curved plate 51 will expand. On the contrary, when the two conveying cylinders 11 move away from each other, the elastic force of the return spring 532 will force the bottom arc plate 52 to move upward, and then drive the top arc plate 51 to rise as a whole. Because the top arc plate 51 itself has elastic deformation, the two sides of the top arc plate 51 will shrink relative to the conveying cylinder 11 at this time, and maintain a sealed sliding abutment, that is, the angle of the lower end surface of the top arc plate 51 is relatively reduced at this time. The above changes ensure that a seal is formed between the bottom sides of the two conveying cylinders 11, and ensure that the two dual-axis conveying mechanisms 1 will maintain their integrity whether they are relatively close or far away, thereby ensuring the normal transportation of refractory materials.

[0035] In the related art, this kind of green refractory material automatic feeding mechanism, because the top curved plate 51 is deformed by its own elasticity, once it is used for a long time, or maintains its stress deformation state for a long time (for example, it is stretched by an expanded angle or squeezed by a reduced angle for a long time), its elastic deformation ability will weaken. When the distance between the two dual-axis conveying mechanisms 1 changes again, it is easy for a gap to appear between the bottom of the two conveying cylinders 11 and the top curved plate 51, causing the conveyed material to leak, affecting the normal conveying and feeding work.

[0036] Example 2: According to some embodiments of this application, Figure 7-Figure 9 As shown, two groups of pre-tightening components 6 are symmetrically arranged between the top arc plate 51 and the bottom arc plate 52. The pre-tightening components 6 include a top L-shaped plate 61 and a bottom L-shaped plate 62 distributed up and down. A pre-tightening part 63 is connected between the top L-shaped plate 61 and the bottom L-shaped plate 62, wherein the top L-shaped plate 61 and the bottom L-shaped plate 62 slide on the top arc plate 51 and the bottom arc plate 52 respectively.

[0037] like Figure 7 and 8 As shown, the lower end of the top arc plate 51 is symmetrically provided with a plurality of bottom T-shaped slots 513 , and the upper end surface of the bottom arc plate 52 is symmetrically provided with a plurality of top T-shaped slots 521 .

[0038] Specifically, such as Figure 8 and 9 As shown, a plurality of top side T-shaped blocks 611 are provided at the top end of the top side L-shaped plate 61, and the plurality of top side T-shaped blocks 611 are slidably provided in the plurality of bottom side T-shaped grooves 513. One end of the top side T-shaped block 611 is fixedly connected with a top side positioning block 612, and a top side positioning screw 613 is slidably inserted on the top side positioning block 612. The top side positioning screw 613 slides through the top side L-shaped plate 61 and is threadedly connected to the conveying cylinder 11.

[0039] It is understandable that a fixed connection is formed between the top L-shaped plate 61 and the conveying cylinder 11 . It is further understandable that the conveying cylinder 11 will drive the top L-shaped plate 61 to move synchronously in the same direction.

[0040] Furthermore, a plurality of bottom T-shaped blocks 621 are provided at the bottom end of the bottom L-shaped plate 62, and the plurality of bottom T-shaped blocks 621 are slidably provided in the plurality of top T-shaped slots 521. One end of the bottom T-shaped block 621 is fixedly connected to a bottom positioning block 622, and a bottom positioning screw 623 is slidably inserted into the bottom positioning block 622, and the bottom positioning screw 623 is threadedly connected to the bottom L-shaped plate 62.

[0041] The pre-tightening member 63 includes a pre-tightening screw 631 and a pre-tightening spring 632. The pre-tightening screw 631 passes through the bottom L-shaped plate 62 and is threadedly connected to the top L-shaped plate 61. The pre-tightening spring 632 is sleeved on the pre-tightening screw 631. The two ends of the pre-tightening spring 632 respectively abut against the end of the pre-tightening screw 631 and the bottom L-shaped plate 62.

[0042] It can be understood that the top L-shaped plate 61 and the bottom L-shaped plate 62 are connected as a whole via the pre-tightening screw 631 .

[0043] Therefore, when the conveying cylinder 11 is displaced, the top L-shaped plate 61 and the bottom L-shaped plate 62 will be driven synchronously and in the same direction to slide on the bottom side of the top arc plate 51 and the top side of the bottom arc plate 52 respectively, and a certain elastic connection is formed between the top L-shaped plate 61 and the bottom L-shaped plate 62 by the preloaded spring 632, that is, the top L-shaped plate 61 can be elastically displaced relative to the bottom L-shaped plate 62. Then, it can be further understood that the top arc plate 51 can be elastically displaced relative to the bottom arc plate 52 (refer to FIG. Figure 8 height direction in the middle); In this way, when the two conveying cylinders 11 move away from each other, the conveying cylinder 11 will respectively pull its corresponding set of top L-shaped plates 61 and bottom L-shaped plates 62 to move synchronously in the same direction, that is, the set of top L-shaped plates 61 and bottom L-shaped plates 62 will slide along the corresponding bottom T-shaped grooves 513 and top T-shaped grooves 521 to the sides of the top curved plate 51 and the bottom curved plate 52 respectively. Since the bottom curved plate 52 does not have the ability to deform, it can be understood that the lower sides of the top curved plate 51 are subjected to the tension provided by the elasticity between the top L-shaped plate 61 and the bottom L-shaped plate 62. The size of the elasticity is determined by the compression amount of the preloaded spring 632. It can be understood that Yes, at this time, a better sealing effect will be formed between the two sides of the top arc-shaped plate 51 and the conveying cylinder 11 under the action of the preloaded spring 632. On the contrary, even when the two conveying cylinders 11 are close to each other, the top L-shaped plate 61 and the bottom L-shaped plate 62 will move toward the center. Because there is an elastic force between the top L-shaped plate 61 and the bottom L-shaped plate 62, they will still apply a downward pulling force to the top arc-shaped plate 51. In this way, it can be understood that this design increases the service life of the top arc-shaped plate 51, avoids its own elastic deformation failure or decline, and causes leakage on the bottom side of the entire dual-axis conveying mechanism 1, thereby improving the service life of the entire feeding mechanism.

[0044] In the related art, in this green refractory material automatic feeding mechanism, since a sealed sliding state needs to be maintained between the top curved plate 51 and the conveying cylinder 11, there will be greater friction between the top curved plate 51 and the conveying cylinder 11. If the top curved plate 51 and the bottom curved plate 52 are fixedly connected only by the connecting screw 511, the top curved plate 51 will form a relatively rigid contact with the conveying cylinder 11, resulting in serious friction between the two, aggravating the wear of the top curved plate 51 itself, especially the sealing between its two side edges and the conveying cylinder 11 will be seriously reduced with wear.

[0045] Example 3: According to some embodiments of this application, Figure 10 and Figure 11 As shown, a buffer assembly 7 is sleeved on the connecting screw 511 , and the buffer assembly 7 is used to enable the top curved plate 51 to have elastic displacement capability when displacement changes occur between the top curved plate 51 and the bottom curved plate 52 .

[0046] Specifically, the buffer assembly 7 includes a buffer tube 71 and a buffer spring 72. The buffer tube 71 is coaxially connected to the sealing ring 512. The end of the connecting screw 511 extends into the buffer tube 71. The buffer spring 72 is sleeved on the connecting screw 511. The two ends of the buffer spring 72 respectively abut the end of the connecting screw 511 and the inner bottom end of the buffer tube 71.

[0047] Therefore, when the top curved plate 51 is pulled downward by the bottom curved plate 52, the connecting screw 511 will first follow the bottom curved plate 52 to move downward and squeeze the buffer spring 72. The top curved plate 51 has a tendency to move downward under the elastic force of the buffer spring 72, and the original rigid downward displacement is transformed into the current elastic downward displacement, which reduces the downward pulling force. In this way, the pressure of the top protrusion of the top curved plate 51 on both sides becomes smaller, that is, the overall deformation of the top curved plate 51 will be weakened. At the same time, the abutment force between the two sides of the top curved plate 51 and the conveying cylinder 11 is also relatively reduced, while ensuring the sealing fit, reducing the gap between the two. The abutment force between them will reduce the friction between the conveying cylinder 11 and the top curved plate 51 when the relative displacement changes occur, thereby improving the service life of the top curved plate 51. Similarly, when the top curved plate 51 is pushed upward by the bottom curved plate 52, the top curved plate 51 will also change the thrust from rigidity to elasticity due to the presence of the buffer spring 72, thereby avoiding large deformation between the top protrusion and the two sides. In this way, the service life of the top curved plate 51 will be further guaranteed, and the presence of the buffer spring 72 and the pre-tightening spring 632 can ensure the sealing and fitting effect between the top curved plate 51 as a whole and the two sides and the conveying cylinder 11.

[0048] It should be noted that the specific models and specifications of the conveying blade 12, conveying motor 13, adjusting motor 31, double-headed screw 32, connecting screw 511, return spring 532, top side positioning screw 613, bottom side positioning screw 623, pre-tightening screw 631, pre-tightening spring 632 and buffer spring 72 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0049] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
