[0038] The feeding port 2 is provided with two, two feeding ports 2 are used for respectively feeding dry materials and wet materials; in use, in this way, the adhesion of dry materials and wet materials caused by feeding raw materials through the same feeding port 2 can be avoided, and the clogging of the feeding port 2 can be further avoided.

[0039] The stirring mechanism 4 comprises a partition plate 41, a discharging plate 46, a stirring plate 47, a support 48 and a discharging groove 49. The partition plate 41 is fixedly connected to the inside of the machine body 1. The main gear 43 and the secondary gear 45 are arranged above the partition plate 41. The discharging plate 46 is fixedly connected to the inside of the machine body 1. The stirring plate 47 is fixedly connected to the outside of the forward screw rod 42. The support 48 is fixedly connected to the inner side of the discharging plate 46. The discharging groove 49 is arranged on the surface of the support 48 and penetrates through the support 48. The top end of the forward screw rod 42 is connected to the motor 3. The forward screw rod 42 is rotationally connected to the partition plate 41. The bottom end of the forward screw rod 42 is rotationally connected to the inside of the support 48. The stirring plate 47 is rotationally connected to the inside of the support 48. The reverse screw rod 44 is rotationally connected to the partition plate 41. The secondary gear 45 is provided with a plurality of uniform angular gears meshing with the outside of the main gear 43. When in use, the motor 3 is powered on to rotate the forward screw rod 42 outside the motor 3. The rotation of the forward screw rod 42 drives the rotation of the main gear 43 and the stirring plate 47. The rotation of the main gear 43 drives the rotation of the secondary gear 45 outside the main gear 43. Thus, the reverse screw rod 44 connected to the secondary gear 45 rotates. The rotation directions of the forward screw rod 42 and the reverse screw rod 44 are opposite, and the screw directions of the forward screw rod 42 and the reverse screw rod 44 are the same. Thus, the rotation of the forward screw rod 42 can convey the dry material and wet material mixture close to the discharging plate 46 and the support 48 to the lower side of the partition plate 41. The rotation of the reverse screw rod 44 can convey the dry material and wet material mixture below the partition plate 41 to the vicinity of the discharging plate 46. The design of the plurality of reverse screw rods 44 can cover more areas inside the machine body 1. Thus, the dry material and wet material mixture between the lower side of the partition plate 41 and the upper side of the discharging plate 46 and the support 48 can be reciprocally mixed and stirred. This can fully mix the substances with large quality and easy to precipitate into the mixture. This stirring method is more suitable for the stirring of actual raw materials. The discharging plate 46 is arranged to facilitate the addition of subsequent auxiliary materials. The rotation of the stirring plate 47 can further stir the mixture passing through the discharging groove 49 and avoid the blockage of the mixture inside the discharging groove 49.

[0040] Please refer to Figures 1-5 The inside of the machine body 1 is provided with a wall-hanging prevention mechanism 5. The inside of the machine body 1 is provided with a collection mechanism 7.

[0041] The wall-hanging prevention mechanism 5 comprises a ring gear 51, a stand 52, a roller 53, a folding rod 54, a scraper 55, and a friction sponge 56. The ring gear 51 is arranged above the partition plate 41, and the inner side of the ring gear 51 is engaged with the secondary gear 45. The stand 52 is fixedly connected to the bottom of the ring gear 51. The stand 52 is provided with a plurality of and uniformly distributed on the bottom of the ring gear 51. The roller 53 is rotatably connected to the inner side of the stand 52. The number of the roller 53 is the same as that of the stand 52. The roller 53 is rollingly connected to the top of the partition plate 41. The surface of the partition plate 41 is provided with a ring-shaped groove which penetrates the partition plate 41. The friction sponge 56 is fixedly connected to the inner side of the ring-shaped groove. The folding rod 54 is provided with a plurality of and uniformly fixedly connected to the bottom of the ring gear 51. The scraper 55 is fixedly connected to the outer side of the folding rod 54. The folding rod 54 is slidingly connected to the inner side of the ring-shaped groove. The scraper 55 is slidingly connected to the inner wall of the machine body 1 and the outer side of the discharging plate 46. The folding rod 54 and the scraper 55 are arranged above the bracket 48. When in use, the synchronous rotation of the plurality of secondary gears 45 can make the ring gear 51 rotate. The arrangement of the stand 52 and the roller 53 can ensure that the ring gear 51 rotates more smoothly on the top of the partition plate 41, avoiding the jamming condition. The rotation of the ring gear 51 can drive the folding rod 54 to rotate, and the rotation of the folding rod 54 can drive the scraper 55 to rotate. The rotation of the scraper 55 can scrape off the sticky substances above the bracket 48, below the partition plate 41, the inner wall of the machine body 1, and the outer side of the discharging plate 46. Thus, the device can not only avoid the mixture sticking to the inside of the device to cause the waste of raw materials to the greatest extent, but also avoid the mixture sticking to the inside of the device for a long time to cause the increase of cleaning difficulty, the obstruction of the operation of the stirring mechanism 4, and the corrosion of the device. The rotation of the folding rod 54 can also assist in stirring the mixture close to the inner wall of the machine body 1. The friction sponge 56 can prevent the mixture from entering the upper side of the partition plate 41 through the ring-shaped groove.

[0042] The connection between the feeding port 2 and the machine body 1 is located below the partition plate 41, avoiding the dry and wet materials from entering the upper side of the partition plate 41 during feeding.

[0043] Please refer to Figures 1-5The auxiliary material spraying mechanism 6 comprises an auxiliary material port 61, a rotating wheel 65, a plurality of dispersion curved plates 66, a feeding pipe 67, a fan 68, an air pipe 69 and a collision plate 610. The auxiliary material port 61 is arranged outside the machine body 1. The rotating wheel 65 is rotatably connected inside the mounting seat 62. The plurality of dispersion curved plates 66 are uniformly fixedly connected outside the rotating wheel 65. The rotating wheel 65 and the dispersion curved plates 66 are arranged inside the circular groove 64. The rotating wheel 65 is connected with a driving motor outside the mounting seat 62. The driving motor is arranged outside the mounting seat 62. The feeding pipe 67 is fixedly connected inside the mounting seat 62. The fan 68 is arranged inside the mounting seat 62. One end of the air pipe 69 is connected with the fan 68. The other end of the air pipe 69 extends into the feeding pipe 67. The collision plate 610 is fixedly connected inside the feeding plate 46. The storage chamber 63 and the feeding pipe 67 are respectively communicated with the top and the bottom of the circular groove 64. When in use, the solid auxiliary material is put into the storage chamber 63 through the auxiliary material port 61. The driving motor is powered on to drive the rotating wheel 65 to rotate clockwise. The clockwise rotation of the rotating wheel 65 drives the dispersion curved plates 66 to rotate clockwise. The clockwise rotation of the dispersion curved plates 66 drives the solid auxiliary material in the storage chamber 63 to enter between the circular groove 64 and the rotating wheel 65. With the rotation of the dispersion curved plates 66, the solid auxiliary material in the circular groove 64 enters the feeding pipe 67. The arrangement of the plurality of dispersion curved plates 66 not only enables the solid auxiliary material in the storage chamber 63 to enter the circular groove 64 uniformly, but also avoids the solid auxiliary material from blocking the connection between the storage chamber 63 and the circular groove 64. The fan 68 is powered on to blow high-speed air. The high-speed air blows into the feeding plate 46 through the air pipe 69 horizontally. Then, the high-speed air drives the solid auxiliary material in the feeding pipe 67 to enter the feeding plate 46. Influenced by the high-speed air, the solid auxiliary material is blown and scattered uniformly in the feeding plate 46 and is uniformly scattered on the surface of the mixture passing through the feeding plate 46, thereby achieving the effect of uniformly covering the mixture. The use of the auxiliary material spraying mechanism 6 can avoid the solid auxiliary material from blocking the discharge port, the feeding speed from being fast or slow and the dispersion from being uneven in the conventional auxiliary material adding equipment, and is more suitable for the use in the actual auxiliary material and medicine adding conditions.

[0044] Please refer to Figures 1-5The collecting mechanism 7 comprises a first inclined plate 71, a second inclined plate 72 and a collecting groove 73. The first inclined plate 71 is fixedly connected to the inner side of the discharging plate 46. The second inclined plate 72 is fixedly connected to the inner side of the discharging plate 46. The first inclined plate 71 is located above the second inclined plate 72. The collecting groove 73 is inserted into the inner bottom of the machine body 1. The fan 68, the air pipe 69 and the anti-collision plate 610 are arranged between the first inclined plate 71 and the second inclined plate 72. In this way, the mixture passing through the discharging plate 46 first flows over the upper surface of the first inclined plate 71 and then flows over the upper surface of the second inclined plate 72 and finally flows into the inner side of the collecting groove 73. The fan 68, the air pipe 69 and the anti-collision plate 610 arranged between the first inclined plate 71 and the second inclined plate 72 can prevent the flowing mixture from directly contacting the fan 68, the air pipe 69 and the anti-collision plate 610, thereby avoiding the situation that the mixture adheres to the outside of the discharging pipe 67, the air pipe 69 and the anti-collision plate 610 and causes the failure of the auxiliary material addition. The anti-collision plate 610 can prevent the auxiliary material or the medicine from impacting the lower surface of the first inclined plate 71 and entering the inside of the discharging pipe 67, thereby further avoiding the reverse movement of the auxiliary material or the medicine. The setting of the first inclined plate 71 and the second inclined plate 72 can reduce the flowing speed of the mixture compared with directly allowing the mixture to fall, thereby avoiding the splashing situation caused by the direct contact between the mixture and the collecting groove 73. After the flowing speed of the mixture is reduced, the auxiliary material can cover a larger area on the surface of the mixture, which is beneficial to the mixing of the auxiliary material and the mixture.

[0045] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or equivalently replace some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
