Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a spiral conveying device capable of being sealed. Background Art

[0002] A spiral conveyor is a machine that uses a motor to drive a spiral to rotate and push materials to achieve the purpose of conveying; it can convey horizontally, obliquely or vertically; spiral conveying can convey materials smoothly. Under the working conditions where the materials need to be compacted and sealed, the existing conveying spiral mechanism generally adopts a variable-diameter spiral. By gradually reducing the pitch and diameter, when the material feeding amount remains unchanged, the spiral conveying amount gradually decreases, and the materials are more and more compacted to achieve the purpose of material plugging. However, if the spiral body has been manufactured, due to the different material properties of the materials themselves, there will be a large difference in the compaction degree of the materials inside the spiral body. Inevitably, some materials will be blocked inside the barrel wall and cannot be discharged, or the compaction degree of the materials is insufficient. If the materials cannot be compacted, it will lead to insufficient discharge blockage and reduce the plugging effect. If you want to adapt to the plugging and conveying of various materials, it is necessary to replace the entire spiral body, which will greatly increase the cost. It is also unrealistic to frequently replace the entire set of facilities in actual production. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0013] The following gives specific embodiments.

[0014] See Figures 1 - 2 , a screw conveyor device capable of being sealed, including a conveyor screw machine main body 1, a screw rod 2, a ventilation hole 3, a ventilation pipe 4, an exhaust hole 5, a connecting thread 6, a reverse push rod 7, a connecting cylinder 8, a bearing seat 13, a transmission shaft 14, a reduction box 15 and a motor 16. A screw rod 2 is rotatably connected to the inner wall of one side of the conveyor screw machine main body 1. A bearing seat 13 is fixedly connected to the outer wall of one end of the conveyor screw machine main body 1. A transmission shaft 14 is rotatably connected in the bearing seat 13, and one end of the transmission shaft 14 is fixedly connected to the screw rod 2. A reduction box 15 is installed on the outer wall of one side of the bearing seat 13. A motor 16 is installed on the outer wall of one side of the reduction box 15, and the output shaft of the motor 16 is connected to the transmission shaft 14 through the reduction box 15. A ventilation pipe 4 is inlaid and installed on one side of the screw rod 2. A ventilation hole 3 is opened in the middle of the screw rod 2, and the bottom end of the ventilation pipe 4 is connected to the inner wall of the ventilation hole 3 in a penetrating manner. Exhaust holes 5 are distributed on the outer wall of one side of the ventilation hole 3. A connecting cylinder 8 is fixedly connected to the outer wall of the other end of the conveyor screw machine main body 1. A reverse push rod 7 is installed on one side of the connecting cylinder 8. A connecting thread 6 is fixedly connected to the outer wall of one end of the reverse push rod 7, and one side of the connecting thread 6 is installed on the outer wall of the screw rod 2; a feeding port 11 is opened at the top end of the conveyor screw machine main body 1. A feeding box 12 is fixedly connected to the outer wall of the top end of the feeding port 11. A bent-arm discharging box 9 is fixedly connected to the outer wall of one side of the connecting cylinder 8. When the material is put into the feeding box 12 and enters the conveyor screw machine main body 1 through the feeding port 11, when discharging is required, it can be discharged through the bent-arm discharging box 9 on the connecting cylinder 8. By setting up a large-angle bent wall, after the compacted material enters the bent-arm discharging box 9, there can be sufficient natural fluffing space, and it can be evenly pressed by the bent-angle pipe wall, so that the compacted material can be cut and fall, and no jamming phenomenon will occur; connecting plates 10 are fixedly connected to the outer walls of the two bottom ends of the conveyor screw machine main body 1 in a distributed manner. The connecting plates 10 on the conveyor screw machine main body 1 are placed at the specified positions, which is convenient to install and fix the connecting plates 10 on the conveyor screw machine main body 1 through screws.

[0015] Working principle: First, place the connecting plate 10 on the main body 1 of the conveying screw conveyor at the designated position, then install and fix the connecting plate 10 on the main body 1 of the conveying screw conveyor with screws. Next, put the material into the internal part of the feed box 12, and the material enters the internal part of the main body 1 of the conveying screw conveyor through the feed port 11. Start the motor 16 and the reduction box 15 to make the transmission shaft 14 on the bearing seat 13 rotate, so that the screw rod 2 conveys the material. Through the blades of the screw rod 2 and the barrel wall of the main body 1 of the conveying screw conveyor, the material is pressed more and more tightly. When the material is relatively loose, the reverse push rod 7 can be started, and the screw rod 2 is pushed reversely through the connecting screw thread 6 to make the material be compacted reversely, so that the material diffuses from the inside to the outside. And during the process of compacting the material, the redundant air can enter the ventilation hole 3 through the exhaust hole 5, and finally be discharged through the ventilation pipe 4, which can realize the discharge of the air in the main body 1 of the conveying screw conveyor to ensure the compactness of compaction. When discharging the compacted material, it is discharged through the bent-arm discharge box 9 on the connecting cylinder 8. The equal-pitch spiral structure is adopted to ensure continuous and powerful feeding, and the material can be compacted. Then, through the reverse push structure, it is convenient for the material cylinder to diffuse from the inside to the outside, the material has a tendency to open, and the material is easier to be dispersed. Moreover, during the compaction process, the air in the material gap is connected to the loose part of the material through the holes to realize air evacuation, making the material easier to be compacted.
