[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0022] Examples, such as Figures 1-5 As shown: This utility model provides a material mixing device, the structure of which includes a frame 1 as the main structure of the device and a mixing mechanism installed in the frame 1. The mixing mechanism is used to mix and output the materials, so that the materials are directly output in a mixed state. The mixing mechanism includes a mixing chamber 2, a hopper 3 installed on the side of the mixing chamber 2, and a feeding mechanism 4. The side of the mixing chamber 2 is provided with an inclined side air vent 2a. The pipeline at the bottom of the mixing chamber 2 generates negative pressure inward. The airflow entering the mixing chamber 2 from the side air vent 2a forms a vortex in the mixing chamber 2. The materials from multiple hoppers 3 enter the mixing chamber 2 and are mixed by the vortex and discharged through the pipeline.
[0023] The feeding mechanism 4 is used for conveying the material in the hopper 3 to the mixing cavity 2, and the feeding mechanism 4 comprises a conveying structure at the bottom end and a guide cover 41 arranged at the upper end of the conveying structure. The guide cover 41 is in the form of a concave cover and cooperates with the conveying structure to form a material moving cavity. Those skilled in the art know that the conveying structure is a conveying device in the form of a bottom-moving conveying belt used for conveying the material carried under the cover of the guide cover 41. For example, the conveying belt nested between a driving belt and another driven pulley driven by a motor is used to convey the material under the cover of the guide cover 41. Here, the guide cover 41 is used to limit the area of the material moving cavity, and the guide cover 41 is arranged on the frame, base or shell required by the structure to be connected with the conveying structure. Those skilled in the art can select the conveying structure according to actual needs, which will not be described here.
[0024] It should be noted that the width of the conveying structure, which is not replaced, is greater than that of the guide cover 41.
[0025] At the same time, the inside end of the mixing cavity 2 is respectively provided with a lower opening 2a and an upper opening 2b for the guide cover 41 and the conveying structure to extend into. The width of the upper opening 2b is usually less than or equal to that of the lower opening 2a. In this embodiment, the width of the upper opening 2b is set to be equal to that of the lower opening 2a, which is convenient for adapting to guide covers 41 of different widths. The width of the guide cover 41 is less than that of the upper opening 2b. In this embodiment, the front section of the guide cover 41 is provided with an arc-shaped cover 43, and the arc of the arc-shaped cover 43 cooperates with the outside of the mixing cavity 2. The cover 43 covers the gap between the guide cover 41 and the upper opening 2b, thereby avoiding material leakage and facilitating the adaptation to guide covers 41 of different widths.
[0026] In order to adapt to guide covers 41 of different widths, the hopper 3 connected with the guide cover 41 is set as follows in this embodiment: the hopper 3 and the guide cover 41 are detachably fixedly connected, the top end of the guide cover 41 is provided with an opening, the bottom end of the hopper 3 is provided with a connecting part 3a in communication with the opening, the connecting part 3a is a passage structure for the hopper 3 to enter the guide cover 41, the front and rear sides of the connecting part 3a are vertically arranged, and the left and right sides of the connecting part 3a are provided with adaptive plates 31. The adaptive plates 31 are swingably connected with the connecting part 3a and are fixedly connected with the guide cover 41 at the bottom end. Specifically, the junction of the hopper 3 and the connecting part 3a is provided with a long strip-shaped buckle, the top end of the adaptive plate 31 is provided with the same buckle and is buckled with the buckle at the junction, and the adaptive plate 31 swings around the buckling position of the two buckles, so that the adaptive plate 31 swings at the left and right sides of the connecting part 3a to adapt to guide covers 41 of different widths.
[0027] Meanwhile, the adaptive plate 31 is hingedly connected to the fixed plate 32 at the bottom end, the fixed plate 32 is fixedly connected to the material guide cover 41, and the adaptive plate 31 is connected to the material guide cover 41 at the bottom end through the fixed plate 32, thereby forming a connection structure from top to bottom, i.e., the hopper 3, the connecting part 3a, the adaptive plate 31, the fixed plate 32, and the material guide cover 41 are sequentially connected, and the adaptive plate 31 forms the two side structures of the connecting part 3a;
[0028] For the remaining front and rear structures, the vertical parts on the front and rear sides of the connecting part 3a are the main base plates 3a1, and the adaptive plate 31 is gap-fitted between the front and rear main base plates 3a1; the front and rear ends of the hole in the top end of the material guide cover 41 are provided with vertical limiting material guide plates 42, the limiting material guide plates 42 cover the gap between the main base plate 3a1 and the material guide cover 41, and the main base plate 3a1 and the limiting material guide plate 42 are gap-fitted, thereby forming the front and rear structures of the connecting part 3a based on the main base plate 3a1, and the limiting material guide plate 42 blocks the gap between the main base plate 3a1 and the material guide cover 41 to assist the formation of the front and rear structures;
[0029] Furthermore, since the upper and lower ends of the adaptive plate 31 on both sides are movably connected, a relatively unstable parallelogram structure is formed, and therefore the left and right sides of the connecting part 3a are fixedly provided with side adjusting plates 3a2, the side adjusting plates 3a2 are fixedly connected to the hopper 3, the main base plate 3a1 and the side adjusting plate 3a2 are connected to form the connecting part 3a, and the adaptive plate 31 is located inside the connecting part 3a as a structure for adjusting the size of the space inside the connecting part 3a, meanwhile, the outer side of the adaptive plate 31 is provided with a connecting frame 33, the side adjusting plate 3a2 is provided with an adjusting bolt 34 through thread engagement, the tail end of the adjusting bolt 34 is movably connected to the connecting frame 33, a T-shaped rod is provided at the tail of the adjusting bolt 34 to hook the connecting frame 33, and the connection between the adjusting bolt 34 and the connecting frame 33 limits the freedom of the adaptive plate 31 to swing around the buckle as the base point, thereby when the adaptive plate 31 needs to be fixedly connected to the material guide cover 41, the adjusting bolt 34 pulls the adaptive plate 31 in the opposite direction through the connecting frame 33, thereby forming a stable tension structure.
[0030] In the embodiment, the material in the plurality of hoppers 3 is sent into the mixing chamber 2 by the conveying structure moving in the cavity formed by the guide cover 41 and the conveying structure, and the material is mixed by the cyclone and discharged through the pipeline. When the material has poor fluidity, a wider cover is needed to keep the material flowing, or when the material flow is large, a wider cover is needed to ensure the material flows smoothly. In this case, the guide cover 41 and the conveying structure are disassembled, the adjusting bolt 34 is then turned outward, the adaptive plate 31 is swung outward, the distance between the two fixed plates 32 is increased, and then the wider guide cover 41 is installed between the two fixed plates 32. At this time, the adaptive plates 31 on both sides will still sway left and right, and then the adjusting bolt 34 is further tightened outward, the adaptive plate 31 on both sides is pulled outward by the adjusting bolt 34, so that the adaptive plate 31 is subjected to tension in different directions while the top of the adaptive plate 31 is fixed. At this time, if the guide cover 41 tends to sway to one side of the hopper 3, the adjusting bolt 34 on the adaptive plate 31 on the other side will pull the adaptive plate 31 so that the bottom of the guide cover 41 will not move in the direction of the tendency, so that the adaptive plate 31 remains stable. Then the conveying structure is installed on the guide cover 41, and the guide cover 41 and the conveying structure are inserted into the mixing chamber 2, so that the hopper can adapt to the guide cover 41 of different widths.
[0031] It should be noted that due to the swing of the adaptive plate 31, the height of the bottom end is different, and the difference caused is small, so the guide cover 41 used is matched with the adaptive plate 31 in the vertical length, so that only the height of the top surface of the guide cover 41 is different, and the conveying structure at the bottom end remains in the original position, and the gap between the front end of the guide cover 41 and the upper opening 2b is covered by the cover 43.
[0032] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.
