The two long side surfaces of the frame 6 are symmetrically fixed with motors 9. The output end of the motor 9 is fixedly installed with a driving wheel 10. The driving wheel 10 and the auxiliary wheel are connected to the track 5. When it is necessary to drive the accessory equipment located below the frame 6 to reciprocate around the inside of the warehouse body 1 to drive the stirring and throwing of the material, the user can control the operation of the motor 9 to drive the driving wheel 10 to rotate, and under the action of the auxiliary wheel 7, cooperate with the track 5 to move stably;

During this process, the transmission gear 17 will cooperate with and drive the driven gear 20 meshing on its surface to rotate until the main shell 23 and the auxiliary shell 26 connected to the driven gear 20 rotate to a position perpendicular to the surface of the first stop cover 16. At this time, the shell will greatly increase the contact effect with the materials, and the throwing operation can be effectively realized during the movement.

[0036] The surface of the first inclined plate 28 is sleeved and connected with the second inclined plate 29, and four of the first inclined plate 28 and the second inclined plate 29 are respectively provided. The side surfaces of the first inclined plate 28 and the second inclined plate 29 are symmetrically fixedly connected with sleeves, wherein the surfaces of four sleeves are embedded and connected with sleeve rods 30, and the surfaces of the other four sleeves are rotatably connected with inclined shafts 32, the surface of the inclined shaft 32 is fixedly connected with a sleeve joint 31, the surface of the sleeve joint 31 is sleeved and connected with a connecting piece 34, the surface of the connecting piece 34 is fixedly connected with a positioning rod 33, the surface of the sleeve rod 30 is sleeved and connected with a connecting rod 36, the surface of the connecting rod 36 is rotatably connected with a sliding sleeve 35, the sliding sleeve 35 is sleeved and connected with the linkage frame 27, and the positioning rod 33 is fixedly connected with the connecting piece 24 During the throwing operation, the unpleasant smell in the material body will volatilize, thereby affecting the surrounding staff. At this time, the user can start the cylinder 25 to control its output end to be retracted, thereby driving the linkage frame 27 on its surface to start to be retracted, and the sliding sleeve 35 connected to the linkage frame 27 will also start to move toward the direction of the cylinder 25. During the process, the sleeve rod 30 connected by the connecting rod 36 will be continuously retracted inward, so that the first inclined plate 28 and the second inclined plate 29 start to rotate, thereby leaking out the hole groove on the surface of the auxiliary shell 26. At this time, the air pump 14 is driven again, and the exhaust pipe 15 cooperates with the air duct 19 to extract the odor from the hole groove, and finally guide it to a suitable environment as needed;

[0037] The frame 37 is provided with three groups, the inner surface of the frame 37 is welded and fixed with a screen 38, the outer side of the screen 38 is fixedly connected with a heat pipe 39, the output end of the heat pipe 39 is sleeved and connected with a telescopic pipe 40, a short side surface of the frame 37 is fixedly installed with an anti-drop sleeve 41 at the edges of both sides, the surface of the anti-drop sleeve 41 is sleeved and connected with an anti-drop rod 42, and a short side surface of the frame 37 is fixedly installed with a positioning node 43 at the middle;

[0038] A folding frame 45 is connected to the surface of the positioning section 43, a sleeve bolt 44 is fixedly installed on the surface of the positioning section 43 near the upper end, a sleeve frame 46 is fixedly installed inside the bin body 1, a motor is fixedly installed on the bottom surface of the sleeve frame 46, a screw rod 47 is fixedly installed on the output end of the motor, and the screw rod 47 is sleeve-connected with the sleeve bolt 44. In the existing chemical raw material production process, chemical reactions are inevitable, and the method of passing hot water through the heat pipe 30 and then slowly heating the screen 38 can provide appropriate heating, thereby increasing the activity of the input reactants, thereby accelerating the reaction rate, thereby shortening the production cycle and improving the efficiency of the production process. High production efficiency, and for some liquid or semi-solid raw materials, it can reduce their viscosity, making them more fluid and more convenient for subsequent stirring processing. By driving the motor, the screw rod 47 can be driven to rotate, and it is linked to the top frame 37 through the sleeve bolt 44. As the sleeve bolt 44 moves up and down, it cooperates with the folding frame 45 to simultaneously control the frame 37 in the middle to move synchronously, thereby changing the distance between the three groups of frames 37, thereby helping to evenly distribute heat, reduce the formation of hot spots and cold spots, to improve the uniformity and efficiency of heating, and can meet the processing needs of different chemical raw materials.

[0039] The working principle of the present invention is as follows: when putting in materials, the user can electrically control the flip cover 2 to rotate, and after waiting for the putting in to be completed, the flip cover 2 can be controlled to be retracted again to keep the interior of the bin body 1 in a relatively closed state. On the one hand, it can prevent material leakage and affect the finished product effect of the chemical raw material production, and on the other hand, it can prevent pollution and affect the surrounding environment. The setting of the stacking bin 4 can stack the input materials to improve the preparation efficiency of the chemical raw material production. When it is necessary to drive the accessory equipment located under the frame 6 to move back and forth around the bin body 1 to drive the stirring and throwing operations of the materials, the user can control the motor 9 to operate, thereby driving the driving wheel 10 to rotate, and under the action of the auxiliary wheel 7, cooperate with the track 5 to move stably, and stir and mix. During the cooperative operation, the user can use the control frame alone to drive the second stop cover 18 to rotate. The inclined main shell 23 and the auxiliary shell 26 will have a stirring effect during the rotation process, and driven by the frame 6 accessories, the materials inside the device are fully mixed. During the processing operation, when the material needs to be flipped, the user can control the drive frame 12 to rotate, and its output end drives the transmission gear 17 to rotate. During this process, the transmission gear 17 will cooperate to drive the driven gear 20 meshing on its surface to rotate until the main shell 23 and the auxiliary shell 26 connected to the driven gear 20 rotate to a position perpendicular to the surface of the first stop cover 16. At this time, the shell will greatly increase the contact effect with the material, and the throwing can be effectively realized during the movement. During the throwing operation, the unpleasant smell in the material body will evaporate, thus affecting the surrounding staff. At this time, the user can start the cylinder 25 to control its output end to retract, thereby driving the linkage frame 27 on its surface to start retracting, and the sliding sleeve 35 connected to the linkage frame 27 will also start to move in the direction of the cylinder 25. During the process, the sleeve rod 30 connected by the connecting rod 36 will be continuously retracted inward, so that the first inclined plate 28 and the second inclined plate 29 start to rotate, thereby leaking the hole groove on the surface of the auxiliary shell 26. At this time, the air pump 14 is driven again, and the exhaust pipe 15 cooperates with the air duct 19 to extract the odor from the hole groove, and finally guide it to a suitable environment as needed. In the existing chemical raw material production process, it is inevitable that A chemical reaction occurs, and hot water is introduced through the heat pipe 30, and then the screen 38 is slowly heated up, which can provide appropriate heating, thereby increasing the activity of the reactants, and then accelerating the reaction rate, thereby shortening the production cycle and improving production efficiency. For some liquid or semi-solid raw materials, their viscosity can be reduced, making them more fluid and more convenient for subsequent stirring treatment. The drive motor can drive the screw rod 47 to rotate, and it is linked to the uppermost enclosure 37 through the sleeve bolt 44. As the sleeve bolt 44 moves up and down, it cooperates with the folding frame 45 to simultaneously control the enclosure 37 in the middle to move synchronously, thereby changing the distance between the three groups of enclosures 37, thereby helping to evenly distribute heat and reduce the formation of hot spots and cold spots.To improve the uniformity and efficiency of heating, and to meet the processing requirements of different chemical raw materials.
