[0032] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0035] As shown in Figs. 1-7, the present application provides a gravity-free mixer, which comprises a housing 1, the inside of the housing 1 is provided with two mixing chambers 11, and the side surfaces of the two mixing chambers 11 are connected.

[0036] The upper and lower sides of the housing 1 are both open, the two ends of the upper side opening of the housing 1 are both rotatably connected with cover plates 12, a support plate 13 is arranged between the two cover plates 12, the support plate 13 is fixed with the housing 1, and the support plate 13 is provided with a feeding pipe 14 on one side.

[0037] A mixing shaft 2 is arranged between the two ends of the mixing cavity 11, and the two ends of the mixing shaft 2 are rotatably connected with rotary shaft sleeves 3 which are rotatably connected with the shell 1.

[0038] A plurality of stirring blades 21 are fixedly arranged in the circumferential direction of the mixing shaft 2, one end of the mixing shaft 2 penetrates through the shell 1 and is fixedly connected with a mixing sprocket 22, one side of the shell 1 is rotatably connected with an auxiliary sprocket 23, one side of the shell 1 is fixedly connected with a mixing driver 24, the output shaft of the mixing driver 24 is fixedly connected with a driving sprocket 25, and the mixing sprocket 22, the auxiliary sprocket 23 and the driving sprocket 25 are wound with a chain 26.

[0039] A bottom plate 4 is fixedly arranged on the lower side of the shell 1, and protective shells 5 are arranged in the mixing cavity 11, and the bottom and the side wall of the protective shell 5 are respectively attached to the upper side of the bottom plate 4 and the inner wall of the mixing cavity 11. The side of the two protective shells 5 adjacent to each other and the upper side of the protective shell 5 are both open.

[0040] The rotary shaft sleeves 3 are each sleeved with a clamping plate 31 which is attached to the inner wall of the mixing cavity 11. The edges of the clamping plates 31 are each provided with a clamping groove 32, and the upper sides of the two ends of the protective shell 5 are each provided with a clamping opening 51 which is clamped into the clamping groove 32 and is adapted to the clamping groove 32.

[0041] The shell 1 is fixed with two discharge drivers 33 corresponding in position to the rotary shaft sleeves 3, and the output shafts of the discharge drivers 33 are respectively fixed with one rotary shaft sleeve 3.

[0042] The middle of the lower side of the bottom plate 4 is fixed with a discharge pipe 41, and the upper end of the inside of the discharge pipe 41 is provided with two baffles 42 which are respectively attached to the bottom of one protective shell 5, and the sides opposite to each other of the two baffles 42 are rotatably connected with the discharge pipe 41. The discharge pipe 41 is fixed with two baffle drivers 43 on one side, and the output shafts of the baffle drivers 43 are respectively fixedly connected with the rotary shafts of the baffles 42.

[0043] In this embodiment, the mixing driver 24, the discharge driver 33 and the baffle driver 43 are all motors.

[0044] When the material is mixed, the state of the protective shell 5 is shown in FIG. 5, the two protective shells 5 are connected, and the upper side opening of the protective shell 5 corresponds to the upper side opening of the shell 1. The two baffles 42 are both in a closed state, at this time the shell 1, the bottom plate 4 and the baffle 42 will support the protective shell 5, so that the protective shell 5 can bear the material.

[0045] When the material is poured into the protective shell 5 through the feeding pipe 14, the mixing driver 24 is started to rotate the two mixing shafts 2 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.

[0046] At this time, the protective shell 5 can bear the impact of the material during the mixing process instead of the shell 1 and the bottom plate 4, thereby reducing the damage to the shell 1 and the bottom plate 4.

[0047] When the material mixing is completed, the two baffles 42 are opened by the baffle driver 43, and the discharging driver 33 is started to rotate the protective shell 5 through the rotating shaft sleeve 3 and the clamping plate 31, so that the openings on the opposite sides of the two protective shells 5 are rotated to the lower side of the protective shell 5, and the upper end of the discharging pipe 41 is exposed, as shown in FIG. 6. At this time, the rotation of the mixing shaft 2 pushes the material into the discharging pipe 41 through the stirring blades 21, and the discharging is completed.

[0048] After the rotation of the protective shell 5, the upper surface of the bottom plate 4 is exposed, and part of the material is left on the upper surface of the bottom plate 4.

[0049] After the material is basically discharged, the protective shell 5 is reset by the discharging driver 33, and the material left on the upper surface of the bottom plate 4 is scraped off during the resetting of the protective shell 5. In combination with the continuous rotation of the mixing shaft 2, the scraped material is directly pushed into the discharging pipe 41, thereby reducing the material residue.

[0050] After the material is completely processed, the inside of the shell 1 can be observed by the workers through the opening of the cover plate 12 to observe the conditions of the stirring blades 21 and the protective shell 5, or to clean the inside of the shell 1.

[0051] If the stirring blades 21 are excessively worn, the stirring blades 21 can be directly replaced through the cover plate 12.

[0052] If the protective shell 5 is excessively worn, the discharging driver 33 is started to make the clamping opening 51 face the side of the protective shell 5, and then the bottom plate 4 is removed, as shown in FIG. 7. Since the clamping opening 51 faces the side of the protective shell 5, the rotating shaft sleeve 3 supports the protective shell 5 through the clamping plate 31 and the clamping groove 32, so that the protective shell 5 is prevented from falling during the removal of the bottom plate 4.

[0053] After the bottom plate 4 is removed, the rotating shaft sleeve 3 drives the protective shell 5 to be replaced to rotate, so that the clamping port 51 faces the upper side of the protective shell 5, and then the protective shell 5 can be taken out from the lower side of the shell body 1. Then the clamping port 51 of the new protective shell 5 faces the upper side of the protective shell 5, and is lifted into the shell body 1 from the lower side of the shell body 1. By clamping the clamping port 51 into the clamping groove 32, the positioning of the protective shell 5 can be completed, and then the discharge driver 33 drives the protective shell 5 to rotate, so that the clamping port 51 of the new protective shell 5 faces the side of the protective shell 5, and finally the bottom plate 4 is installed back.

[0054] In summary, the effect of conveniently replacing the protective shell 5 is achieved, and through the replacement of the protective shell 5 and the blocking of the impact of the material shell body 1 and the bottom plate 4 by the protective shell 5, the maintenance cost of the gravity-free mixing machine is reduced.
