Description

Technical Field

[0001] The utility model relates to the technical field of stirrers, in particular to a spiral stirrer. Background Art

[0002] The spiral agitator is a widely used mixing equipment with the advantages of simple structure, low cost and good mixing effect. It is mainly composed of a horizontal trough and a shaft equipped with spiral blades. The material enters the trough from the feeding end, and is gradually moved to the discharging end and discharged after being mixed and pushed by the rotating blades.

[0003] When using a spiral agitator to stir two or more materials, the efficiency of adding the materials one by one is low. When adding multiple materials into the hopper at the same time, the materials are easily blocked at the feed port of the hopper, causing the rate at which the materials enter the agitator to slow down, resulting in low efficiency when using the agitator. Utility Model Content

[0004] The utility model aims to solve the problem that when a spiral agitator is used to stir two or more materials, the efficiency of adding materials sequentially is low, and when multiple materials are added into a hopper at the same time, the materials are easily blocked at the feed port of the hopper, resulting in a slow rate of materials entering the agitator, and the efficiency of using the agitator is low. A spiral agitator is proposed to solve the problem that when a spiral agitator is used to stir two or more materials, the efficiency of adding materials sequentially is low, and when multiple materials are added into the hopper at the same time, the materials are easily blocked at the feed port of the hopper, resulting in a slow rate of materials entering the agitator, and the efficiency of using the agitator is low.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a spiral agitator comprises a machine body, one end of which is provided with a first motor, an output end of the first motor is fixedly connected to a spiral agitator rod, one end of the spiral agitator rod rotates on the inner wall of the machine body, an end of the outer surface of the machine body away from the first motor is provided with a discharge trough, a feed hopper is provided at the top of the machine body, an auxiliary device is provided on the outer surface of the feed hopper, the auxiliary device comprises a rotating shaft and a pushing block, both ends of the rotating shaft rotate on the inner wall of the feed hopper, a second motor is provided on one side of the feed hopper, the output end of the second motor is fixedly connected to one end of the rotating shaft, A plurality of round rods are fixedly connected to the outer surface of the rotating shaft, a disc is fixedly connected to one end of the rotating shaft away from the second motor, a protrusion is fixedly connected to one side of the disc, a slide groove is opened at the top of the body, the bottom end of the push block slides on the inner wall of the slide groove, a U-shaped plate is fixedly connected to one side of the push block, the bottom end of the U-shaped plate slides on the inner wall of the slide groove, a spring is arranged on one side of the U-shaped plate, a rectangular plate is fixedly connected to the top of the body, two ends of the spring are respectively fixedly connected to one end of the U-shaped plate and one side of the rectangular plate, one end of the push block and one end of the U-shaped plate are respectively fixedly connected to rectangular rods, and one end of the rectangular rod is provided with a knocking block with the help of a convenient device.

[0006] The effect achieved by the above components is: by setting a second motor, when the material is added to the interior of the machine body through the feed hopper, the second motor can be operated, and the output end of the second motor drives the rotating shaft to rotate on the inner wall of the feed hopper, and the round rod on the outer surface of the rotating shaft is used to stir the outlet of the feed hopper to avoid material blockage as much as possible. At the same time, the rotation of the rotating shaft will drive the disc to rotate. When the disc rotates and the protrusion pushes the push block away, it will drive the U-shaped plate to move and compress the spring at the same time. When the push block moves to the farthest distance, the knocking block on the outer surface of the rectangular rod at one end of the U-shaped plate will knock the outer surface of the feed hopper, causing the feed hopper to vibrate. When the protrusion is away from the outer surface of the push block, the spring will return to its original state and push the U-shaped plate and the push block to move toward the disc. At this time, when the push block moves to the farthest distance, the knocking block on the outer surface of the rectangular rod at one end of the push block will knock the outer surface of the feed hopper, causing the feed hopper to vibrate, further avoiding material blockage inside the feed hopper.

[0007] Preferably, the outer surface of the projection is arc-shaped at an edge of one end away from the disc, and the outer surface of the push block on a side close to the disc is an inclined surface.

One end of the push block 27 and one end of the U-shaped plate 28 are respectively fixedly connected with a rectangular rod 29, and one end of the rectangular rod 29 is provided with a knocking block 210 by means of a convenient device 3. By providing a second motor 21, when the material is added to the interior of the machine body 1 through the feed hopper 7, the second motor 21 can be operated, and the output end of the second motor 21 drives the rotating shaft 22 to rotate on the inner wall of the feed hopper 7, and the round rod 23 on the outer surface of the rotating shaft 22 stirs the outlet of the feed hopper 7 to avoid material blockage as much as possible. At the same time, the rotation of the rotating shaft 22 drives the disc 24 to rotate.

By setting the knocking block 210 made of rubber material, the knocking block 210 will not make a large abnormal sound when knocking the outer surface of the feed hopper 7. A positioning block 214 is fixedly connected to one side of the rectangular rod 29, and one side of the positioning block 214 slides on one side of the feed hopper 7. When the rectangular rod 29 is driven to move horizontally by the U-shaped plate 28 and the push block 27, one side of the positioning block 214 will slide on one side of the feed hopper 7. The rectangular rod 29 and the feed hopper 7 can be aligned by the positioning block 214. The angle between them is further limited to avoid the angle of the rectangular rod 29 from being deflected as much as possible. A positioning rod 213 is provided at one end of the U-shaped plate 28 close to the spring 212. The outer surface of the positioning rod 213 slides on the inner wall of the rectangular plate 211. The positioning rod 213 is located inside the spring 212. When the U-shaped plate 28 moves, the positioning rod 213 will slide on the inner wall of the rectangular plate 211. The internal shape of the spring 212 can be reinforced by the positioning rod 213 to avoid lateral deformation of the spring 212 when it is compressed or stretched, which affects the normal use of the spring 212.

At the same time, the rotation of the rotating shaft 22 will drive the disc 24 to rotate. When the disc 24 rotates to make the protrusion 25 push the push block 27 away, it will drive the U-shaped plate 28 to move and compress the spring 2 at the same time. 12. When the push block 27 moves to the farthest distance, the rubber knocking block 210 on the outer surface of the rectangular rod 29 at one end of the U-shaped plate 28 will knock the outer surface of the feed hopper 7, causing the feed hopper 7 to vibrate. When the protrusion 25 moves away from the outer surface of the push block 27, the spring 212 will return to its original state and push the U-shaped plate 28 and the push block 27 to move toward the disc 24. At this time, when the push block 27 moves to the farthest distance, the knocking block 210 on the outer surface of the rectangular rod 29 at one end of the push block 27 will knock the outer surface of the feed hopper 7, causing the feed hopper 7 to vibrate, further preventing the material from being blocked inside the feed hopper 7. After the material enters the interior of the machine body 1, the first motor 4 drives the spiral stirring rod 5 to rotate to stir and mix the material. After mixing, the material will be output through the discharge trough 6 at one end of the machine body 1.
