DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-4 A double-screw plow-type stirring device comprises a barrel body 1, a connecting pipe 101 is fixedly connected to the top of the barrel body 1, a connecting plate 102 is fixedly connected to the top of the connecting pipe 101, a servo motor 103 is fixedly connected to the top of the connecting plate 102, and further comprises:

[0023] The bottom of the servo motor 103 is fixedly connected with a rotating shaft 2, and the rotating shaft 2 passes through the connecting pipe 101 and extends to the inside of the barrel body 1. The inner wall of the rotating shaft 2 is slidably connected with a rotating column 201, and a spring 202 is fixedly connected between the rotating column 201 and the rotating shaft 2. A plurality of plow blades 203 are fixedly connected to the side wall of the rotating column 201. A collision column 204 is fixedly connected to the side wall of the rotating column 201 located at the bottom of the inner cavity of the barrel body 1;

[0024] A collision block 205 is fixedly connected to the inner bottom wall of the barrel body 1, and the collision block 205 is set in a semicircular shape. A discharge pipe 206 is fixedly connected to the bottom of the barrel body 1, and the rotating column 201 can extend to the inner cavity of the discharge pipe 206;

[0025] It should be noted that: the material is placed in the inner cavity of the barrel body 1, and then the servo motor 103 located at the top of the connecting plate 102 is turned on, the servo motor 103 will drive the rotating shaft 2 to rotate, and the rotating shaft 2 will drive the rotating column 201 to rotate during the rotation process, and the rotating column 201 will drive the plough blade 203 to rotate, and the plough blade 203 will stir the material located in the inner cavity of the barrel body 1 during the rotation process, and the rotating column 201 will drive the collision column 204 on the bottom side wall to rotate during the rotation process, and the collision column 204 will collide with the collision block 205 when it rotates. Since the collision block 205 is set to be semicircular, the collision column 204 During the collision with the collision block 205, the rotating column 201 will slide in the inner cavity of the rotating shaft 2, squeezing the spring 202 between the rotating column 201 and the rotating shaft 2 to generate a rebound force. When the collision column 204 moves away from the collision block 205, under the action of the rebound force of the spring 202, the rotating column 201 will move downward again, thereby causing the rotating column 201 to swing up and down at the same time during the rotation process, causing the plow-type blade 203 to move up and down, thereby allowing the material inside the barrel body 1 to be evenly mixed up and down, and when the discharge pipe 206 is opened to discharge material, the rotating column 201 will also extend to the inner cavity of the discharge pipe 206 when moving downward, thereby enhancing the discharge effect of the discharge pipe 206 and avoiding blockage.

[0026] Reference Figure 1-4 , both side walls of the rotating shaft 2 are provided with sliding grooves 3, and both side walls of the rotating column 201 are fixedly connected to the limiting columns 301;

[0027] The limiting column 301 passes through the rotating shaft 2 through the sliding groove 3, and the limiting column 301 and the rotating shaft 2 are in sliding connection;

[0028] It should be noted that: since the limiting column 301 connected to the side wall of the rotating column 201 passes through the rotating shaft 2, and the limiting column 301 is slidably connected to the sliding groove 3 opened on the side wall of the rotating shaft 2, when the rotating shaft 2 rotates, the rotating column 201 is driven to rotate through the limiting column 301, and the rotating column 201 can slide up and down on the inner wall of the rotating shaft 2.

[0029] Reference Figure 1-4 A feed pipe 302 is fixedly connected to the side wall of the connecting pipe 101, and a plurality of cutters 303 are fixedly connected to the side wall of the rotating shaft 2 located inside the connecting pipe 101;

[0030] The cutters 303 and the plow blades 203 are arranged at equal intervals and sizes, and are evenly distributed around the rotating shaft 2;

[0031] It should be noted that: when the material is fed from the feed pipe 302 into the inner cavity of the connecting pipe 101, since the side wall of the rotating shaft 2 located in the inner cavity of the connecting pipe 101 is fixedly connected with the cutter 303, the cutter 303 will be driven to rotate during the rotation of the rotating shaft 2, thereby cutting and dispersing large pieces of material, making it easier to stir and mix the material evenly afterwards.

[0032] Operation method: put the material from the feed pipe 302 into the inner cavity of the connecting pipe 101, and turn on the servo motor 103 located on the top of the connecting plate 102 at the same time. The servo motor 103 will drive the rotating shaft 2 to rotate. Since the side wall of the rotating shaft 2 located in the inner cavity of the connecting pipe 101 is fixedly connected with the cutter 303, the cutter 303 will be driven to rotate during the rotation of the rotating shaft 2, thereby cutting and dispersing large pieces of material, which is convenient for subsequent stirring and mixing of the material. After the material is cut, it enters the inner cavity of the barrel body 1. Since the limiting column 301 connected to the side wall of the rotating column 201 penetrates the rotating shaft 2, and the limiting column 301 is slidably connected to the slide groove 3 provided on the side wall of the rotating shaft 2, when the rotating shaft 2 rotates, the rotating column 201 is driven to rotate through the limiting column 301, and the rotating column 201 can slide up and down on the inner wall of the rotating shaft 2;

[0033] The rotating column 201 rotates to drive the plow blade 203 to rotate. During the rotation of the plow blade 203, the material in the inner cavity of the barrel body 1 is stirred, and the rotating column 201 drives the collision column 204 on the bottom side wall to rotate during the rotation. When the collision column 204 rotates, it collides with the collision block 205. Since the collision block 205 is set as a semicircle, during the collision between the collision column 204 and the collision block 205, the rotating column 201 will slide in the inner cavity of the rotating shaft 2, and the rotating column 201 and the rotating shaft 2 The spring 202 between them produces compression to generate a rebound force. When the collision column 204 moves away from the collision block 205, the rotating column 201 will move downward again under the action of the rebound force of the spring 202, so that the rotating column 201 will swing up and down at the same time during the rotation process, and the plow-type blade 203 will also move up and down, so that the material inside the barrel body 1 can be evenly mixed up and down, and when the discharge pipe 206 is opened to discharge the material, the rotating column 201 will also extend to the inner cavity of the discharge pipe 206 when moving downward, thereby enhancing the discharge effect of the discharge pipe 206 and avoiding blockage.
