DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1-5The feeding mechanism of a mixer shown in the figure includes a base plate 1, a lifting cylinder 2, and a mixer body 15. The mixer body 15 is arranged on the top of the base plate 1. Four mounting shafts 3 are fixedly installed on the peripheral outer wall of the lifting cylinder 2, wherein the ends of two mounting shafts 3 are rotatably installed with first fixed plates 4, and the bottoms of the two first fixed plates 4 are fixedly installed on the base plate 1. Two second fixed plates 6 are slidably installed on the top of the base plate 1 through a sliding assembly, and a rectangular frame 5 is fixedly installed on the top of the two second fixed plates 6. The other two mounting shafts 3 are respectively slidably installed in the two rectangular frames 5. A lifting auger 13 is rotatably installed on the relative inner walls of the lifting cylinder 2. A lifting motor 14 is arranged at the end of the lifting cylinder 2, and the output shaft of the lifting motor 14 is connected to the end of the lifting auger 13. A feeding hopper 12 and a discharge pipe are respectively arranged on the peripheral outer wall of the lifting cylinder 2, and the discharge pipe is connected to the mixer body 15.

[0025] With the help of the above structure, when in use, first place the raw material in the feed hopper 12 and let it fall into the lifting cylinder 2, start the lifting motor 14 to drive the lifting auger 13 to rotate, lift the raw material to the discharge pipe and drop it into the mixer body 15 for mixing. When it is necessary to adjust the angle of the lifting cylinder 2 to adapt to different types of mixer bodies 2, the two second fixed plates 6 are driven by the sliding assembly to move horizontally synchronously, and then the two rectangular frames 5 are driven to move synchronously. The horizontal movement of the rectangular frame 5 squeezes two of the mounting shafts 3, thereby adjusting the inclination angle of the lifting cylinder 2, thereby realizing the height adjustment function of the discharge pipe, which is very practical.

[0026] like Figure 2 As shown, the sliding assembly includes two sliders 7, two sliding grooves are opened on the top of the base plate 1, and screw rods 8 are rotatably installed on the relative inner walls of the two sliding grooves. The two sliders 7 are respectively threadedly installed on the two screw rods 8, and the two screw rods 8 are connected by a transmission unit. The tops of the two sliders 7 are respectively connected to the bottoms of the two second fixed plates 6. The advantage of such an arrangement is that the synchronous horizontal movement function of the two second fixed plates 6 can be realized through the arrangement of the two screw rods 8 and the two sliders 7.

[0027] Specifically, when the angle adjustment is required, the two screw rods 8 are rotated to drive the two sliders 7 and the two second fixed plates 6 to move horizontally synchronously under the action of the threads. The two rectangular frames 5 squeeze the two mounting shafts 3 to drive the lifting cylinder 2 to achieve the angle adjustment function. The operation is convenient and the practicability is strong.

[0028] like Figure 3As shown, the transmission unit includes two sprocket wheels 9, which are fixedly sleeved on two screw rods 8 respectively, and a chain 10 is installed on the two sprocket wheels 9 in meshing with each other. A motor slot is opened on the inner wall of the side of one of the slide grooves, and a driving motor 11 is fixedly installed in the motor slot. The output shaft of the driving motor 11 is connected to the end of one of the screw rods 8. The advantage of such an arrangement is that, through the arrangement of the two sprocket wheels 9 and the chain 10, the function of driving the two screw rods 8 to rotate synchronously can be realized, thereby preventing jamming during adjustment.

[0029] Specifically, the driving motor 11 is started to drive one of the screw rods 8 to rotate, and then the other screw rod 8 is driven to rotate synchronously under the meshing action of the two sprockets 9 and the chain 10, so as to avoid jamming during the angle adjustment of the lifting cylinder 2.

[0030] like Figure 4 As shown, a rotating shaft 16 is rotatably mounted on the top inner wall of the mixer body 15, a stirring motor 17 is fixedly mounted on the top of the mixer body 15, an output shaft of the stirring motor 17 is connected to the end of the rotating shaft 16, a circulating auger is arranged on the rotating shaft 16, and a stirring assembly is arranged on the rotating shaft 16. The advantage of such an arrangement is that, through the arrangement of the circulating auger, the rotating shaft 16 can be driven to rotate synchronously when it rotates, thereby lifting the raw materials.

[0031] Specifically, the stirring motor 17 is started to drive the rotating shaft 16 and the circulating auger to rotate synchronously, so that the raw materials at the bottom are lifted to the top to achieve circulating stirring, thereby improving the stirring effect.

[0032] like Figure 5 As shown, the stirring assembly includes a fixed plate 18, which is fixedly sleeved on the rotating shaft 16. Two rotating holes are opened at the bottom of the fixed plate 18. Stirring shafts 19 are rotatably installed in the two rotating holes. The two stirring shafts 19 are provided with self-rotation units. The outer walls of the two stirring shafts 19 are provided with multiple stirring blades 22. The advantage of such an arrangement is that, through the arrangement of two stirring shafts 19 and multiple stirring blades 22, the raw materials in the mixer body 15 can be fully stirred, the stirring efficiency is greatly improved, and the practicality is stronger.

[0033] like Figure 5 As shown, the rotation unit includes a rotation gear 20, which is fixedly sleeved on the stirring shaft 19, and an annular rack 21 is fixedly installed on the top inner wall of the mixer body 15. The rotation gear 20 is meshed with the annular rack 21. The advantage of this arrangement is that, through the arrangement of the rotation gear 20 and the annular rack 21, the rotation function can be achieved through their meshing action when the stirring shaft 19 revolves.

[0034] Specifically, when the rotating shaft 16 rotates, it drives the fixed plate 18 and the two stirring shafts 19 to rotate synchronously. When the two stirring shafts 19 are moving, they are driven to rotate by the meshing action of the self-rotating gear 20 and the annular rack 21, thereby improving the stirring and mixing effect.

[0035] like Figure 4 As shown, the multiple stirring blades 22 arranged on the two stirring shafts 19 are all arranged in opposite directions. The advantage of such an arrangement is that the stirring effect can be improved by setting the directions of the stirring blades 22 on the two stirring shafts 19 to be opposite.

[0036] Specifically, when the two stirring shafts 19 are rotating, the plurality of stirring blades 22 are driven to rotate synchronously. Since the two stirring blades are arranged in opposite directions, the stirring effect can be greatly improved.

[0037] 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.
