[0031] Example 1

[0032] like Figure 1-5 As shown, the utility model proposes an anti-material-caking screw conveyor, comprising a conveyor body 1, on which a feed pipe 2 and a discharge pipe 3 are provided, a threaded conveying rod is rotatably installed in the conveyor body 1, and a driving motor 4 for driving the threaded conveying rod to rotate is fixedly installed on one side of the conveyor body 1.

[0033] In this embodiment, a feed box 5 is fixedly installed on the feed pipe 2, and a box door 7 is rotatably installed in the feed box 5. A control component for controlling the opening and closing of the box door 7 is provided in the feed box 5, and the control component includes a fixed plate 11 fixedly installed in the feed box 5, and rectangular boxes 111 are fixedly installed at both ends of the fixed plate 11. The rectangular boxes 111 are used to hold excess materials. The two rectangular boxes 111 are both close to the two side walls of the feed box 5, and a first rotating shaft 20 is rotatably installed at the inner opening of one of the rectangular boxes 111, and a second rotating shaft 21 is rotatably installed at the inner opening of the other rectangular box 111. A movable plate 113 is provided on the first rotating shaft 20 and the second rotating shaft 21, and a weight sensor 23 is fixedly installed at the bottom of the rectangular box 111.

[0034] Among them, the control component also includes an inclined plate 112 fixedly installed inside the rectangular box 111, a first rotating shaft 20 passes through one end of the feed box 5 and is fixedly installed with a first pulley 18, a second rotating shaft 21 passes through one end of the feed box 5 and is fixedly installed with a second pulley 13, a first belt 14 is sleeved between the first pulley 18 and the second pulley 13, the first pulley 18 is cross-transmitted with the adjacent second pulley 13 through the first belt 14, and the auxiliary pulley 19 is rotated through the second belt 16 to drive the first pulley 18 to rotate, thereby driving the second pulley 13 to rotate through the first belt 14, so that the first rotating shaft 20 and the second rotating shaft 21 rotate in opposite directions, so that the movable plate 113 rotates to the bottom of the rectangular box 111, so that the material located in the rectangular box 111 enters the feed box 5 along the inclined plate 112 and then enters the conveyor body 1 through the feeding pipe 2, so as to avoid material accumulation in the rectangular box 111.

[0035] The control assembly also includes a third rotating shaft 22 rotatably mounted on the top of the feed box 5, one side of the box door 7 is fixedly connected to the third rotating shaft 22, one end of the third rotating shaft 22 that passes through the feed box 5 is fixedly mounted with a third pulley 15, a mounting plate is fixedly mounted on the feed box 5, a servo motor 17 is fixedly mounted on the mounting plate, and the output shaft of the servo motor 17 is fixedly connected to the central axis of the third pulley 15. The servo motor 17 is started to drive the third pulley 15 to rotate, thereby rotating the third rotating shaft 22, rotating the box door 7, and closing the opening of the feed box 5, thereby preventing excessive material from entering the feed box 5, thereby avoiding material agglomeration caused by filling too much material into the screw conveyor.

[0036] Among them, the control component also includes an auxiliary pulley 19 fixedly mounted on the first pulley 18, a second belt 16 is sleeved between the auxiliary pulley 19 and the third pulley 15, and the weight sensor 23 is connected to the servo motor 17 through a wire. When the weight sensor 23 at the bottom of the rectangular box 111 detects that the weight of the rectangular box 111 exceeds the set value, the weight sensor 23 transmits a signal to the servo motor 17.

[0037] Example 2

[0038] like Figure 2As shown, based on Example 1, a rotating rod 10 is rotatably installed in the feed box 5, and a plurality of stirring plates 8 are fixedly installed on the rotating rod 10.

The output shaft of the rotating motor 9 is fixedly connected to one end of the rotating rod 10. The plurality of stirring plates 8 are distributed in a circular array along the center of the rotating rod 10. A plurality of through holes are opened on the stirring plates 8. The rotating motor 9 is started to rotate the rotating rod 10, thereby driving the stirring plates 8 to rotate, and preliminarily breaking up the material entering the feed box 5 so that the material can fall into the feed pipe 2 evenly.

[0039] Working principle: In the working process of the utility model, the material is firstly put into the feed box 5 through the feed funnel 6, and the rotating motor 9 is started to make the rotating rod 10 rotate, thereby driving the stirring plate 8 to rotate, and the material entering the feed box 5 is preliminarily scattered so that the material can fall into the feed pipe 2 evenly. When there is too much material entering the conveyor body 1, the excess material will accumulate in the feed box 5. At this time, part of the material will enter the rectangular box 111. When the weight sensor 23 at the bottom of the rectangular box 111 detects that the weight of the rectangular box 111 exceeds the set value, the weight sensor 23 transmits a signal to the servo motor 17, starts the servo motor 17, and drives the third pulley 15 to rotate, thereby causing the third rotating shaft 22 fixedly connected to the third pulley 15 to rotate. The box door 7 is rotated to close the opening of the feed box 5, thereby preventing excessive material from entering the feed box 5, thereby preventing material agglomeration caused by filling too much material into the screw conveyor; at the same time, the auxiliary pulley 19 fixedly mounted on the first pulley 18 is rotated through the second belt 16, driving the first pulley 18 to rotate, thereby driving the second pulley 13 to rotate through the first belt 14, so that the first rotating shaft 20 and the second rotating shaft 21 rotate in opposite directions, so that the moving plate 113 arranged on the first rotating shaft 20 and the second rotating shaft 21 rotates to the bottom of the rectangular box 111, so that the material located in the rectangular box 111 enters the feed box 5 along the inclined plate 112 and then enters the conveyor body 1 through the feeding pipe 2, thereby preventing the material from accumulating in the rectangular box 111.
