The storage chamber 2 is directly used for storing lithium manganate raw materials. The outer wall of the storage chamber 4 is in contact with the inner wall of the separate chamber 2, and the working principle of the pressure sensor 3 is based on the conversion relationship between pressure and weight. When the raw materials are put into the storage chamber 4, the storage chamber 4 generates pressure on the pressure sensor 3, the pressure sensor 3 converts this pressure signal into an electric signal and transmits it to the control system. The inner wall of the proximal side of a plurality of storage chambers 4 is fixedly connected with an electric push rod 5, the driving end of the electric push rod 5 is fixedly connected with a switch block 6, and the electric push rod 5 is the power source for controlling the opening and closing of the discharge port 7. When the raw materials need to be matched, start the electric push rod 5, and the electric push rod 5 generates power and drives the switch block 6 to move linearly along its own axis.

[0032] The bottom of the storage chamber 4 is provided with a discharge port 7, which is a channel for the raw materials to flow out of the storage chamber 4. The switch block 6 is driven by the electric push rod 5 to realize the opening and closing control of the discharge port 7. The bottom of the switch block 6 is in contact with the top of the discharge port 7. The inner bottom side of the storage box 1 is fixedly connected with a plurality of discharge pipes 8, and the top end of the storage box 1 is rotatably connected with a plurality of top covers 9. The top cover 9 is opened in a rotating manner, which is convenient to operate and can better cooperate with the storage box 1 when closed. The top side of the storage chamber 4 is in contact with the bottom side of the top cover 9. The bottom end of the storage box 1 is fixedly connected with a material collecting box 10. The discharge pipe 8 is used to guide the raw materials flowing out of the discharge port 7 into the material collecting box 10, and the material collecting box 10 is used to collect the raw materials falling from the discharge pipe 8. The inside of the storage box 1 is provided with a plurality of partitions 11, which play a role in separating the internal space of the storage box 1. The bottom corners of the material collecting box 10 are fixedly connected with support rods 18, which mainly provide stable support for the material collecting box 10. The bottom ends of the plurality of support rods 18 are fixedly connected with a bottom plate 19, which provides bottom support for the entire batching machine. The top end of the bottom plate 19 is detachably connected with a material collecting barrel 20, which is a container for finally collecting the lithium manganate raw materials falling from the material collecting box 10.

[0033] Referring to Figure 1 , Figure 2 and Figure 4 , the inside of the partition 11 is fixedly connected with a sealing assembly for protecting the raw materials. The sealing assembly includes a plurality of air cylinders 12, which are the power source of the sealing assembly. The outside of the plurality of air cylinders 12 is fixedly connected to the inside of the plurality of partitions 11 on the opposite side, and the driving end of the air cylinder 12 is fixedly connected with a support block 13. The outer wall of the plurality of support blocks 13 is slidingly connected to the inner wall of the storage box 1, and the support block 13 moves outward under the drive of the air cylinder 12. The left and right inner walls of the support block 13 are rotatably connected with transmission plates 14, which are driven by the support block 13 to rotate. The opposite sides of the two transmission plates 14 are rotatably connected with T-shaped sliding blocks 15, and the opposite sides of the plurality of partitions 11 are provided with T-shaped sliding grooves in the inner wall. The outer wall of the two T-shaped sliding blocks 15 is slidingly connected to the inner wall of the T-shaped sliding groove. The T-shaped sliding block 15 moves to both sides along the T-shaped sliding groove under the drive of the transmission plate 14, and the T-shaped sliding groove can ensure the accuracy of the moving direction of the T-shaped sliding block 15, avoiding deviation during movement.

When the T-shaped sliding block 15 moves to both sides, the extrusion block 16 moves to both sides, extruding the inclined groove 17 in the top cover 9. Due to the inclined structure of the inclined groove 17, the top cover 9 moves downward, so that the top cover 9 and the storage box 1 fit more tightly, increasing the sealing effect of the top cover 9 on the storage box 1, and also realizing the opening and closing of the top cover 9.

[0034] Working principle: first by opening the top cover 9 lithium manganese oxide raw materials into the storage chamber 4, the pressure sensor 3 will record the total weight of the storage chamber 4 and the internal components and raw materials, when the raw materials need to be mixed, by starting the electric push rod 5 power driven switch block 6 along the axis of the electric push rod 5 linear movement, thereby achieving the switch block 6 movement to control the opening and closing of the discharge port 7, when the raw materials through the discharge port 7 and the discharge pipe 8 into the material box 10, the total weight of the raw materials and the storage chamber 4 and its internal components will change, by the pre-set value can make the pressure sensor 3 in the specific weight change after control electric push rod 5 retract switch block 6 to close the discharge port 7, the exact amount of raw materials will enter the material box 10 and fall into the collection barrel 20, the workers can take down the collection barrel 20 to continue subsequent production and processing, using the pressure sensor 3 can detect the raw materials in the storage chamber 4, in order to add when the raw materials are insufficient;

[0035] When the lithium manganese oxide raw materials in the storage chamber 4 need to be stored, by rotating the top cover 9 on the top side of the storage box 1, and then by starting the cylinder 12 to generate power to drive the support block 13 to move outward, the outward movement of the support block 13 drives the transmission plate 14 to rotate, and the T-shaped sliding groove guides the T-shaped sliding block 15, thereby achieving the rotation of the transmission plate 14 driving the T-shaped sliding block 15 to move to both sides, and the T-shaped sliding block 15 moves to both sides to drive the extrusion block 16 to move to both sides, thereby achieving the extrusion of the extrusion block 16 to the inclined slot 17 in the top cover 9. Due to the inclined design of the inclined slot 17, when the extrusion block 16 moves to both sides, the inclined slot 17 moves downward, so that the top cover 9 and the storage box 1 fit more tightly, thereby increasing the sealing effect of the top cover 9 on the storage box 1, reducing the pollution of dust or impurities in the raw materials in the storage chamber 4.

[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
