[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. 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.

[0056] like Figures 1 to 4 As shown, in at least one embodiment, a feeding system is provided, comprising: a feeding device 1, which is arranged at an angle, and comprises: a feeding pipe 11, a feeding mechanism and a moving mechanism; the feeding mechanism is arranged in the feeding pipe 11; the moving mechanism is sleeved on the feeding mechanism, and the moving mechanism is arranged in the feeding pipe 11; the feeding mechanism is suitable for conveying materials from bottom to top; the moving mechanism is suitable for moving when materials are accumulated in the feeding pipe 11; it is realized that the space for material accumulation in the feeding pipe 11 is adjusted during the material conveying process to avoid the material blocking the feeding port of the feeding pipe 11, thereby ensuring the material conveying efficiency.

[0057] The feeding pipe 11 is arranged at an angle, and the feeding port of the feeding pipe 11 is arranged near the bottom end of the feeding pipe 11. There is a partial space between the bottom end of the spiral blade on the driving shaft 142 and the bottom end of the feeding pipe 11, that is, the part of the driving shaft 142 near its tail end is not provided with a spiral blade, and the moving mechanism is arranged at a position where the spiral blade is not provided. The material entering the inclined feeding pipe 11 may accumulate in this partial space due to the uncertain amount of material fed by the spiral blade during the rotation process, resulting in the blocking of the feeding port. There is a spiral blade on the driving shaft 142 directly below the feeding port. When the material accumulation increases, it will squeeze the moving mechanism to move toward the tail end of the feeding pipe 11, thereby increasing the space where the spiral blade is not provided and avoiding the blocking of the feeding port.

[0058] like Figure 3 and Figure 4 As shown, the moving mechanism includes: a moving block 12; the outer wall of the moving block 12 contacts the inner wall of the feeding pipe 11 to prevent the material from passing through the inner wall of the feeding pipe 11 and the outer wall of the moving block 12 and entering the sleeve 131; the moving block 12 is sleeved on the driving shaft 142 in the feeding mechanism; the moving block 12 is slidably connected with the driving shaft 142; the moving block 12 is arranged near the bottom end of the driving shaft 142; a protrusion 121 is arranged on the outer wall of the moving block 12; one end face of the feeding pipe 11 contacts the end face of the rotating ring 13; a strip groove 111 is provided on the inner wall of the feeding pipe 11, and the protrusion 121 is located in the strip groove 111; an annular groove is provided on the inner wall of the feeding pipe 11, and the annular groove is connected with the strip groove 111; the The annular groove is arranged closer to the rotating ring 13 than the strip groove 111; the length direction of the strip groove 111 is parallel to the axial direction of the feeding pipe 11; in the initial state, there is no material accumulated at the position where the spiral blade is not arranged in the feeding pipe 11, and the protrusion 121 is located in the strip groove 111. The cooperation between the protrusion 121 and the strip groove 111 prevents the moving block 12 from rotating. When more and more material is accumulated between the moving block 12 and the bottom end of the spiral blade, the moving block 12 will be squeezed, so that the moving block 12 moves downward, and the space between the moving block 12 and the bottom end of the spiral blade increases, so as to prevent the accumulated material from blocking or clogging the feed port, thereby ensuring that the material can continuously enter the feeding pipe 11; the size of the strip groove 111 can be smaller than the size of the material to prevent the material from entering the strip groove 111.

[0059] The moving mechanism further includes: a rotating ring 13; the rotating ring 13 is arranged on the driving shaft 142, and the rotating ring 13 rotates following the driving shaft 142; the rotating ring 13 is closer to the bottom end of the driving shaft 142 than the moving block 12; a sleeve 131 is arranged on the side of the rotating ring 13 close to the moving block 12; the inner diameter of the sleeve 131 is larger than the outer diameter of the moving block 12, so that the moving block 12 can enter the sleeve 131 easily; a stop bar 132 corresponding to the protrusion 121 is arranged on the side of the sleeve 131 close to the moving block 12; the length direction of the stop bar 132 is parallel to that of the sleeve The axis of the cylinder 131 is parallel; in the initial state, the top of the baffle 132 is closer to the rotating ring 13 than the bottom of the protrusion 121. At this time, when the rotating ring 13 drives the baffle 132, the baffle 132 will not contact the protrusion 121. As the material accumulation increases, the moving block 12 approaches the rotating ring 13, and the protrusion 121 moves from the strip groove 111 to the ring groove. At this time, when the rotating ring 13 drives the baffle 132 to rotate, the baffle 132 will contact the protrusion 121, driving the moving block 12 to rotate, and the arc block 122 rotates synchronously. The rotating arc block 122 will stir the accumulated materials to prevent the accumulated materials from getting stuck with each other and causing the feed port to be stuck.

[0060] A spring 133 is arranged between the moving block 12 and the rotating ring 13; the spring 133 is sleeved on the driving shaft 142; one end of the spring 133 contacts a side of the moving block 12 close to the rotating ring 13, and the other end of the spring 133 contacts the rotating ring 13 after passing through the sleeve 131; after part of the accumulated material is conveyed by the spiral blades, the accumulated material is reduced, and at this time, the moving block 12 is moved away from the rotating ring 13 by resetting the spring 133, so that the material in the space where the spiral blades are not arranged can be pushed forward, so that the part of the material can be conveyed by the spiral blades; the end of the spring 133 that contacts the moving block 12 is not connected to the moving block 12.

[0061] A pair of arc blocks 122 are arranged on one side of the moving block 12 away from the rotating ring 13 , and one side of the arc block 122 away from the rotating ring 13 is an inclined surface so that the accumulated materials can be stirred when the arc block 122 rotates.

[0062] The arc blocks 122 are arranged along the circumference of the end surface of the moving block 12 ; there are intervals between the arc blocks 122 to better stir the material.

[0063] A sponge layer 134 is provided on the inner wall of the sleeve 131; lubricating oil is absorbed in the sponge layer 134; the sponge layer 134 is located between the inner wall of the sleeve 131 and the spring 133; when the moving block 12 moves toward the rotating ring 13, the moving block 12 will contact and squeeze the sponge layer 134, and squeeze the lubricating oil in the sponge layer 134 onto the driving shaft 142. Since the accumulation of materials will cause the load of the driving shaft 142 to increase, the heat generation at the bottom end of the driving shaft 142 will be aggravated. At this time, the extruded lubricating oil can assist in the heat dissipation on the driving shaft 142, reduce heat transfer, and avoid the influence of heat on the material; after the accumulated material is reduced, the moving block 12 is reset by the spring 133, and the squeezed sponge layer 134 recovers its deformation at this time, and the lubricating oil is re-absorbed into the sponge layer 134.

[0064] like Figure 2 As shown, the feeding mechanism includes: a driving motor 14 and a transmission component 141; the driving motor 14 is connected to the bottom end of the driving shaft 142 through the transmission component 141, and the transmission component 141 is tilted, that is, the output shaft of the driving motor 14 and the driving shaft 142 are not in the same straight line, and the output shaft of the driving motor 14 is higher than the driving shaft 142, so as to avoid the materials in the tilted feeding pipe 11 from entering the driving motor 14 when they are piled up downwards, thereby avoiding affecting the driving motor 14; spiral blades are arranged on the outer wall of the driving shaft 142; the driving motor 14 rotates the driving shaft 142 through the transmission component 141, thereby driving the spiral blades to rotate, and the materials can be transported upward; a discharge port is opened at a position close to the top of the feeding pipe 11, and the materials transported upward enter the next process through the discharge port.

[0065] A silo 2 is disposed above the feeding pipe 11 , and the silo 2 is connected to a feed port of the feeding pipe 11 ; the feed port is disposed close to the bottom end of the driving shaft 142 .

[0066] In the initial state, there is no material accumulated at the position where the spiral blade is not set in the feeding pipe 11. At this time, the protrusion 121 is located in the strip groove 111. The cooperation between the protrusion 121 and the strip groove 111 prevents the moving block 12 from rotating. When more and more materials are accumulated between the moving block 12 and the bottom end of the spiral blade, the moving block 12 will be squeezed, so that the moving block 12 moves downward, and the space between the moving block 12 and the bottom end of the spiral blade increases, so as to prevent the accumulated materials from blocking or blocking the feed port, thereby ensuring that the materials can continuously enter the feeding pipe 11; the moving block 12 approaches the rotating ring 13, and the protrusion 121 moves from the strip groove 111 to the ring groove, and at this time the rotating ring 13 drives the baffle When 132 rotates, the baffle 132 will contact the protrusion 121, driving the moving block 12 to rotate, and the arc block 122 will rotate synchronously. The rotating arc block 122 will stir the accumulated materials to prevent the accumulated materials from getting stuck with each other and causing the feed port to be stuck; when the moving block 12 moves toward the rotating ring 13, the moving block 12 will contact and squeeze the sponge layer 134, and squeeze the lubricating oil in the sponge layer 134 onto the driving shaft 142. Since the accumulation of materials will cause the load on the driving shaft 142 to increase, the heat generation at the bottom end of the driving shaft 142 will intensify. At this time, the extruded lubricating oil can assist in dissipating the heat on the driving shaft 142, reduce heat transfer, and avoid the influence of heat on the material.

[0067] In at least one other embodiment, a working method using the above-mentioned feeding system is also provided, including: conveying materials from bottom to top through the feeding mechanism; and the moving mechanism moves when the materials are accumulated in the feeding pipe 11.

[0068] In summary, through the feeding device 1, the feeding device 1 is tilted and includes: a feeding pipe 11, a feeding mechanism and a moving mechanism; the feeding mechanism is arranged in the feeding pipe 11; the moving mechanism is sleeved on the feeding mechanism, and the moving mechanism is arranged in the feeding pipe 11; the feeding mechanism is suitable for conveying materials from bottom to top; the moving mechanism is suitable for moving when materials are accumulated in the feeding pipe 11; it is realized that the space for material accumulation in the feeding pipe 11 is adjusted during the material conveying process to avoid the material blocking the feeding port of the feeding pipe 11, thereby ensuring the material conveying efficiency.
