The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0034] like Figure 1-7 As shown, the present application provides a zero-gravity mixer, including a shell 1 , wherein two mixing chambers 11 are arranged inside the shell 1 , and the sides of the two mixing chambers 11 are connected.

[0035] The upper and lower sides of the shell 1 are both open, and both ends of the upper opening of the shell 1 are rotatably connected with cover plates 12. A support plate 13 is arranged between the two cover plates 12. The support plate 13 is fixed to the shell 1, and a feed pipe 14 is arranged on one side of the support plate 13.

[0036] A mixing shaft 2 is disposed between the two ends of the mixing chamber 11 . Both ends of the mixing shaft 2 are rotatably connected with a rotating shaft sleeve 3 , and the rotating shaft sleeve 3 is rotatably connected to the housing 1 .

[0037] A plurality of stirring blades 21 are fixedly installed on the circumference of the mixing shaft 2. One end of the mixing shaft 2 extends through the shell 1 and is fixedly connected to a mixing sprocket 22. An auxiliary sprocket 23 is rotatably connected to one side of the shell 1. A mixing driver 24 is fixedly connected to one side of the shell 1. The output shaft of the mixing driver 24 is fixedly connected to a driving sprocket 25. A chain 26 is wound between the mixing sprocket 22, the auxiliary sprocket 23 and the driving sprocket 25.

[0038] The bottom opening of the housing 1 is fixedly mounted with a bottom plate 4, and a protective shell 5 is provided inside the mixing chamber 11, and the bottom and side walls of the protective shell 5 are respectively in contact with the upper side of the bottom plate 4 and the inner wall of the mixing chamber 11. The adjacent sides of the two protective shells 5 and the upper side of the protective shells 5 are both open.

[0039] The rotating sleeve 3 is sleeved with a fixed clamping plate 31, which is in contact with the inner wall of the mixing chamber 11. The edges of the clamping plate 31 are provided with clamping grooves 32, and the upper sides of both ends of the protective shell 5 are provided with clamping openings 51, which are inserted into the clamping grooves 32, and the clamping openings 51 are adapted to the clamping grooves 32.

[0040] Two discharging drivers 33 corresponding to the positions of the rotating sleeves 3 are fixed on one side of the housing 1 , and the output shafts of the discharging drivers 33 are respectively fixed to one rotating sleeve 3 .

[0041] A discharge pipe 41 is fixed in the middle of the lower side of the bottom plate 4, and two baffles 42 are arranged at the upper end of the discharge pipe 41. The baffles 42 are respectively fitted with the bottom of a protective shell 5, and the opposite sides of the two baffles 42 are rotatably connected to the discharge pipe 41. Two baffle drivers 43 are fixed on one side of the discharge pipe 41, and the output shafts of the baffle drivers 43 are respectively fixedly connected to the rotating shafts of one baffle 42.

[0042] In this embodiment, the mixing driver 24 , the discharging driver 33 and the baffle driver 43 are all motors.

[0043] When the materials are mixed, the protective shell 5 is in the state as follows Figure 5As shown, the two protective shells 5 are connected, and the upper opening of the protective shell 5 corresponds to the upper opening of the shell 1. Both baffles 42 are in a closed state, and the shell 1, the bottom plate 4 and the baffle 42 support the protective shell 5 so that the protective shell 5 can carry materials.

[0044] The material can be poured into the protective shell 5 through the feed pipe 14, and the mixing driver 24 is started. The mixing driver 24 drives the two mixing shafts 2 to rotate through the mixing sprocket 22, the auxiliary sprocket 23, the driving sprocket 25 and the chain 26, so that the stirring blades 21 stir and mix the material.

[0045] At this time, during the mixing process, the protective shell 5 will replace the shell 1 and the bottom plate 4 to withstand the impact of the materials, thereby reducing the damage to the shell 1 and the bottom plate 4.

[0046] After the material mixing is completed, the baffle driver 43 drives the two baffles 42 to open, and at the same time the discharging driver 33 is started. The discharging driver 33 drives the protective shell 5 to rotate through the rotating sleeve 3 and the clamping plate 31, so that the openings on the opposite sides of the two protective shells 5 rotate toward the lower side of the protective shell 5, thereby exposing the upper end of the discharging pipe 41. Figure 6 At this time, the rotation of the mixing shaft 2 will drive the stirring blades 21 to push the material into the discharge pipe 41 to complete the discharge.

[0047] After the protective shell 5 rotates, a portion of the upper surface of the bottom plate 4 is exposed, which may cause some materials to remain on the upper surface of the bottom plate 4 .

[0048] After the material is basically discharged, the discharging driver 33 drives the protective shell 5 to reset. During the resetting process of the protective shell 5, the residual material on the upper surface of the bottom plate 4 will be scraped out. With the continuous rotation of the mixing shaft 2, the scraped material will be directly pushed into the discharging pipe 41 to reduce the residual material.

[0049] After all materials have been processed, by opening the cover plate 12 , the staff can observe the inside of the housing 1 , the conditions of the stirring blades 21 and the protective shell 5 , or clean the inside of the housing 1 .

[0050] If the stirring blades 21 are worn out too much, the stirring blades 21 can be directly replaced through the cover plate 12 .

[0051] If the protective shell 5 is worn too much, the discharging driver 33 is started first, so that the engaging opening 51 faces the side of the protective shell 5, and then the bottom plate 4 is removed. Figure 7 As the engaging opening 51 faces the side of the protective shell 5 , the rotating sleeve 3 supports the protective shell 5 through the engaging plate 31 and the engaging groove 32 , so as to prevent the protective shell 5 from falling off during the removal of the bottom plate 4 .

[0052] After the bottom plate 4 is removed, the rotating sleeve 3 drives the protective shell 5 to be replaced to rotate and reset, so that the snap-fitting opening 51 faces the upper side of the protective shell 5, and the protective shell 5 can be taken out from the lower side of the shell 1. Then, the snap-fitting opening 51 of the new protective shell 5 faces the upper side of the protective shell 5, and is lifted from the lower side of the shell 1 into the shell 1. By snapping the snap-fitting opening 51 into the snap-fitting slot 32, the positioning of the protective shell 5 can be completed, and then the discharging driver 33 drives the protective shell 5 to rotate, so that the snap-fitting opening 51 of the new protective shell 5 faces the side of the protective shell 5, and finally the bottom plate 4 is installed again.

[0053] In summary, the effect of facilitating replacement of the protective shell 5 is achieved, and the maintenance cost of the zero-gravity mixer is reduced by replacing the protective shell 5 and shielding the impact of the material shell 1 and the bottom plate 4 by the protective shell 5 .
