In order to ensure uniform mixing, the materials need to be stirred vertically and horizontally through several devices. Loading and discharging materials takes a lot of time and has low work efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a novel mixing and stirring machine for the above-mentioned problems. The mixing and stirring work is performed uninterruptedly during the feeding, stirring and discharging of materials, thereby improving the production efficiency.

[0004] The technical scheme adopted by the present invention is: a new type of mixing and stirring machine, comprising: an outer shell, a drum spiral blade group, a central axis blade group, and a driving reduction motor, wherein the outer shell is a drum, one end of which is provided with a feed cover, the feed cover is sealed and welded to the drum of the outer shell, a feed port is provided in the middle of the feed cover, a discharge hole is provided on the drum wall at the other end of the drum, a discharge collection cover is provided on the periphery of the discharge hole, a discharge port is provided at the lower end of the discharge collection cover, and a group of supporting wheels is provided at the lower part of the drum; the drum spiral blade group is a group of evenly distributed spiral blades, the spiral blades are evenly distributed along the axis of the drum, the outer ends of the spiral blades are welded to the inner side walls of the drum, the spiral direction of the spiral curved blades is a positive spiral direction, the spiral angle of the spiral curved blades of the spiral blade group is between 20 degrees and 30 degrees, and the length of the spiral curved blades is the same as the length of the drum;

[0005] The central axis blade group comprises: a central axis and a group of axial flow central axis blades evenly distributed along the axis of the central axis, the central axis blade group is arranged on the inner side of the central axis blade spiral blade, one end of the central axis facing the discharge hole is connected with the outer shell end face of the outer shell cylinder on the side of the discharge hole through a bearing, a central axis driving gear is provided on the central axis at this end, a roller driving gear is provided in the middle of the outer shell end face on the side of the discharge hole, the roller driving gear is fixedly connected with the outer shell end face through a connecting piece, the driving motor drives the roller spiral blade group and the central axis blade group to rotate through double gears and chains, the end of the central axis facing the feed port is connected with the central axis connecting plate through a bearing, a feed hole is provided on the central axis connecting plate, a feed hood is provided on the outer side of the central axis connecting plate, the rotation speed of the central axis blade group is higher than the rotation speed of the roller spiral blade group, and the central axis blade drives the material flow toward the discharge hole.

[0006] The width of the spiral curved blades of the drum spiral blade group is greater than 10 centimeters.

[0007] The beneficial effects of the present invention are as follows: since the drum spiral blade group and the central axis blade group are arranged in the drum, the drum spiral blades continuously lift, flip and throw down the materials to be mixed. Since they are spiral blades, each time the materials are thrown down, the materials will move a little distance backwards. While throwing down, the central axis blades rotate and stir the thrown materials through the central axis blades and transmit the mixed materials forwards for a distance. The spiral blades scatter the materials backwards while the central axis blades gradually transport and stir the materials forwards. The scattering and stirring are repeated in this way. The materials are continuously mixed and gradually move forwards to the discharge port while being mixed. There is no need to load them in first and then transport them out after mixing as in traditional equipment. This saves the time of frequent loading and unloading and improves efficiency. Since the parts of the mixer in contact with the mixed materials are constantly moving, there is no dead angle in the mixing, and the mixing is fast and uniform. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] like Figures 1 to 9As shown, the present invention comprises: a housing 1, a drum spiral blade group 6, a central shaft blade group 7, and a driving reduction motor 5. The housing is a drum, and one end of the drum is provided with a feed cover 11, which is sealed and welded to the rear side end of the drum of the housing. Figure 3 and Figure 4 A feed port 111 is provided in the middle of the feed cover 11. The mixed materials are transported into the drum through the pipe 112 during use. Discharge holes 13 are evenly distributed around the wall of the other end of the drum. A collection cover 4 for discharging materials is provided around the discharge holes. A discharge port 41 is provided at the lower end of the discharge collection cover. The collection cover does not rotate during use. A set of supporting wheels 3 is provided at the lower part of the drum. The supporting wheels make the front and rear of the drum in a horizontal state, but it does not exclude the state that the rear side is higher than the front side.

[0018] Reference Figures 4 to 9 The drum spiral blade group 6 is a group of spiral blades 61 that are evenly distributed. In this embodiment, there are 8 spiral blades. The width of the spiral curved surface of the spiral blade is greater than 10 cm. The spiral angle of each spiral curved surface blade of the drum spiral blade group is between 20 and 30 degrees, that is, the spiral blade rotates 360 degrees. In this embodiment, the rotation only accounts for one-eighteenth to one-twelfth of a circle, which makes the material fall more effectively. The blade width is generally set between 10 and 40 cm. The radial part of the curved surface of each spiral blade is set radially. The length of the spiral blade is the same as that of the drum of the outer shell. The outer end of the spiral blade is welded to the inner wall of the drum. The spiral direction of the spiral curved surface blade is the positive spiral direction. The positive spiral direction is the perspective in the front. The spiral blade spirals in a clockwise direction, such as Figure 7 and Figure 8 As shown. Since it is welded on the inner wall of the drum, the drum and the drum spiral blade group rotate synchronously in the clockwise direction during operation. The rotation direction is as follows Figure 7 Indicated by arrow direction.

[0019] Reference Figure 8 and Fig. 9 The central axis blade group 7 includes: a central axis 72 and a group of axial flow central axis blades 71 evenly distributed along the central axis, a group is a plurality of central axis blades 71 arranged along the central axis at intervals of 20 to 40 cm, and the central axis blade group is arranged on the inner side of the spiral blade and can rotate. Figure 4The end of the central axis 72 facing the discharge hole is connected to the outer shell end face 14 on the discharge hole side of the outer shell cylinder through a bearing, and a central axis driving gear 73 is provided on the central axis at this end, and a roller driving gear 15 is provided in the middle of the outer shell end face 14 on the discharge hole side, and the roller driving gear is fixedly connected to the outer shell end face through a connecting piece 151. The driving motor 5 drives the roller spiral blade group and the central axis blade group to rotate through a double gear 51 and a chain 52. The end of the central axis facing the feed port is provided with a central axis connecting plate 16, and 4-8 feed holes 161 are provided around the central axis connecting plate. A feed cover 11 is provided on the outer side of the central axis connecting plate. Since the feed cover is a trumpet-shaped cover, the material quickly slides along the trumpet-shaped cover to the impeller mixing area for mixing after entering. Different speeds can be adjusted by setting the size of the transmission gear. The speed of the central axis blade group is higher than the speed of the roller spiral blade group. The central axis blade drives the material flow direction toward the discharge hole. Since the spiral blades of the drum have a certain width, the spiral blades of the drum will continuously lift the materials to be mixed as the drum rotates. As the inclination angle of the blades gradually increases, the materials will continuously slide from the blades and fall off the spiral blades. Since it is a spiral blade, each time the material is thrown down, the material will move a little distance backward. At the same time, the middle axis blades will stir the materials thrown down to the middle oil blades through the rotation of the middle axis blades and transmit the mixed materials forward a little distance. This is repeated, and the materials are continuously mixed and gradually move forward while mixing and gradually enter the discharge port. There is no need to load them in first and then transport them out after mixing like traditional equipment, which saves the time of frequent loading and unloading, improves efficiency, and the mixing is more uniform without dead ends.
