The output of the stirring motor 6 A movable disk 7 is connected to the shaft, a rectangular rod 71 is connected to the bottom of the movable disk 7, a spiral stirring rod 8 is rotatably connected to the mixing barrel 1, the spiral stirring rod 8 can stir the raw materials, the rectangular rod 71 and the spiral stirring rod 8 are slidably connected, and scrapers 9 are evenly spaced and connected to the lower part of the spiral stirring rod 8, the scrapers 9 can scrape the raw materials at the bottom of the mixing barrel 1, a stirring assembly is provided at the bottom of the mixing barrel 1, the stirring assembly is used to stir the raw materials, the left and right sides of the bottom of the mixing barrel 1 are connected with guide rods 14 by bolts, two baffles 15 are connected between the guide rods 14, the baffles 15 can block the bottom of the mixing barrel 1, and the two baffles 15 are in contact with each other.

[0035] like Figure 4 As shown, the stirring assembly includes a mounting frame 10, a fixed bevel gear 11, a stirring shaft 12 and a rotating bevel gear 13. The mounting frame 10 is connected to the bottom of the mixing barrel 1, the spiral stirring rod 8 and the mounting frame 10 are rotatably connected, a fixed bevel gear 11 is installed at the bottom of the mounting frame 10, and the lower part of the spiral stirring rod 8 is rotatably connected to the stirring shaft 12 at even intervals. The stirring shaft 12 is used to stir the raw materials, and the inner ends of the stirring shafts 12 are connected to the rotating bevel gears 13, and the rotating bevel gears 13 and the fixed bevel gears 11 are meshed.

[0036] The stirring motor 6 is driven by the stirring motor 6 to drive the movable plate 7 to rotate, and the movable plate 7 drives the rectangular rod 71 to rotate, thereby driving the spiral stirring rod 8 and the scraper 9 to rotate. The spiral stirring rod 8 can stir the raw materials, and the scraper 9 can scrape up the raw materials at the bottom of the stirring barrel 1. The spiral stirring rod 8 can also push the raw materials at the bottom of the stirring barrel 1 upward, and the pushed raw materials will fall down again. This reciprocating process can increase the movement amplitude of the raw materials and prevent the raw materials from settling at the bottom of the stirring barrel 1. The spiral stirring rod 8 can also drive the stirring shaft 12 and the rotating bevel gear 13 to rotate. The rotating bevel gear 13 rotates on the fixed bevel gear 11, thereby causing the stirring shaft 12 to rotate. The stirring shaft 12 can also stir the raw materials, making the raw materials more evenly stirred. After the stirring of the raw materials is completed, the stirring motor 6 is turned off, and then the baffle 15 is opened. The stirred raw materials in the stirring barrel 1 fall down and people can collect them. Example

[0037] On the basis of Example 1, Figure 1 、 Figure 6 and Figure 7 As shown, it also includes a storage mechanism 17, which includes a loading frame 171 and a baffle plate 172. Four loading frames 171 are connected to the upper part of the support frame 2 at even intervals around the circumferential direction. The loading frames 171 are used to store raw materials. The bottom of the loading frames 171 is provided with a discharge hole 173, and the lower part of the loading frames 171 is slidably provided with a baffle plate 172, which can block the discharge hole 173.

[0038] like Figure 1 、 Figure 8 、 Figure 9 and Figure 10 As shown, it also includes a feeding mechanism 18, which includes a feeding frame 181, a first elastic member 182, a round head rod 183 and a lifting motor 184. The feeding frame 171 is slidably provided with a feeding frame 181 at the bottom, and the feeding frame 181 is wound with a first elastic member 182. One end of the first elastic member 182 is connected to the feeding frame 171, and the other end of the first elastic member 182 is connected to the feeding frame 181. The first elastic member 182 is a spring. The inner side of the feeding frame 181 is connected to the round head rod 183 by screws, and the round head rod 183 is in contact with the movable disk 7. The top of the support frame 2 is connected to the lifting motor 184 by bolts, and the screw rod 51 and the output shaft of the lifting motor 184 are connected by a coupling.

[0039] like Figure 6 and Figure 7 As shown, a transparent plate 22 is also included, and the outer side of the loading frame 171 is embedded with the transparent plate 22.

[0040] People can pour the raw materials into the loading frame 171 for storage. People can observe the raw material reserves in the loading frame 171 through the transparent plate 22. When the raw materials need to be stirred, people open the baffle plate 172 and then control the output shaft of the lifting motor 184 to rotate forward. The lifting motor 184 drives the screw rod 51 to rotate, and the screw rod 51 drives the guide frame 5 to move upward. The guide frame 5 drives the stirring motor 6 to move upward. The stirring motor 6 drives the movable plate 7 to move upward. The movable plate 7 pushes the round head rod 183 to move outward. The round head rod 183 drives the material receiving frame 181 to move outward. The first elastic member 182 is compressed. When the material receiving frame 181 and When the discharge holes 173 correspond, the raw materials in the loading frame 171 fall into the receiving frame 181 through the discharge holes 173, and then fall into the unloading frame 3, so that people can conveniently pour the raw materials into the mixing barrel 1. After there are enough raw materials in the mixing barrel 1, the baffle plate 172 is closed, and then the output shaft of the lifting motor 184 is controlled to reverse, and the lifting motor 184 drives the screw rod 51 to rotate in the opposite direction, and the screw rod 51 drives the guide frame 5 to move downward, and the movable disk 7 moves downward accordingly. The movable disk 7 no longer pushes the round head rod 183, and the receiving frame 181 moves inward and resets under the action of the first elastic member 182, and then people turn off the lifting motor 184.

[0041] like Figure 11 、 Figure 12 and Figure 13 As shown, the discharging mechanism is also included, which includes a second elastic member 191, a pull rope 192, a push plate 193 and a third elastic member 194. Two second elastic members 191 are wound around the guide rod 14, one end of the second elastic member 191 is connected to the guide rod 14, and the other end of the second elastic member 191 is connected to the baffle 15. The second elastic member 191 is a spring, and a pull rope 192 is connected to the bottom of the baffle 15. The pull rope 192 slides through the spiral stirring rod 8, and a push plate 193 is slidably provided in the spiral stirring rod 8. The pull rope 192 is connected to the push plate 193, and the push plate 193 is evenly spaced and connected to the third elastic member 194 between the push plate 193 and the spiral stirring rod 8. The third elastic member 194 is a spring.

[0042] Initially, the second elastic member 191 is in a stretched state. After the mixing of the raw materials is completed, people control the output shaft of the lifting motor 184 to rotate forward, driving the movable disc 7 and the rectangular rod 71 to move downward. The rectangular rod 71 pushes the push plate 193 to move downward, the third elastic member 194 is compressed, and the pull rope 192 is relaxed. The baffle 15 moves outward under the action of the second elastic member 191. The baffle 15 no longer blocks the bottom of the mixing barrel 1, and the mixed raw materials in the mixing barrel 1 fall downward, which makes it convenient for people to discharge the mixed raw materials. After all the mixed raw materials in the mixing barrel 1 are discharged, people control the output shaft of the lifting motor 184 to rotate forward, driving the rectangular rod 71 to move upward, and the rectangular rod 71 no longer pushes the push plate 193. The push plate 193 moves upward and resets under the action of the third elastic member 194. The push plate 193 drives the baffle 15 inward through the pull rope 192 to block the bottom of the mixing barrel 1. The second elastic member 191 is stretched. After the two baffles 15 come into contact, the lifting motor 184 is turned off.

[0043] like Figure 14 As shown, it also includes a knocking mechanism 21, which includes a contact rod 211, a knocking rod 212 and a fifth elastic member 213. The top of the movable disk 7 is connected to the contact rod 211 by screws at uniform intervals around the circumferential direction, and the inner side of the loading frame 171 is rotatably connected to the knocking rod 212. A fifth elastic member 213 is connected between the knocking rod 212 and the loading frame 171, and the fifth elastic member 213 is a torsion spring.

[0044] When the movable disk 7 rotates, the movable disk 7 drives the contact rod 211 to rotate. When the contact rod 211 rotates and contacts the knocking rod 212, the contact rod 211 pushes the knocking rod 212 to rotate, and the fifth elastic member 213 is deformed. When the contact rod 211 rotates and does not contact the knocking rod 212, the knocking rod 212 rotates in the opposite direction under the action of the fifth elastic member 213. The knocking rod 212 knocks the loading frame 171, causing the loading frame 171 to vibrate, thereby avoiding blockage of raw materials in the loading frame 171.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
