[0024] A raw material tank cover plate that is easy to install and disassemble provided in an embodiment of the present application is now described.

[0025] See also Figure 1 , is a schematic diagram of the structure of the utility model. The raw material tank cover plate that is easy to install and disassemble includes a base 1 and a cover plate 2 that is connected to the base 1. The base 1 is provided with a through hole for feeding; the edge of the cover plate 2 is provided with a plurality of semi-enclosed positioning holes 3, and the positioning hole 3 includes a receiving section 301 and a limiting section 302. The limiting section 302 is open, and the minimum width of the limiting section 302 is smaller than the minimum width of the receiving section 301. The base 1 is rotatably connected with a plurality of positioning rods 4 corresponding to the positioning holes 3. A handle 5 is provided on the top of the positioning rod 4. The handle 5 cooperates with the receiving section 301 of the positioning hole 3. The limiting section 302 of the positioning hole 3 is used to limit the handle 5, and then limit the positioning rod 4. Specifically, the positioning rod 4 is arranged on the base 1, which is not easy to lose, and the staff does not need to be distracted to store the positioning rod 4.

[0026] During use, when it is necessary to open the raw material tank cover 2, the staff rotates the positioning rod 4 to make it leave the positioning hole 3, thereby completing the opening of the cover 2; when it is necessary to close the raw material tank cover 2, the staff rotates the positioning rod 4 to make it enter the positioning hole 3, so that the handle 5 cooperates with the accommodating section 301 of the positioning hole 3, and the limiting section 302 of the positioning hole 3 limits the handle 5 so that it will not fall off from the positioning hole 3, thereby completing the closing of the cover 2.

[0027] See also Figure 1 and Figure 2Specifically, the width of the bottom of the handle 5 is smaller than the maximum width of the accommodating section 301 of the positioning hole 3, and larger than the minimum width on the limiting section 302 of the positioning hole 3, so that the bottom of the handle 5 is accommodated by the accommodating section 301 of the positioning hole 3 and will not fall off along the limiting section 302 of the positioning hole 3. The positioning rod 4 is limited by limiting the handle 5 to achieve the closure of the cover 2.

[0028] Furthermore, the handle 5 can be moved along the positioning rod 4. Specifically, in the present embodiment, a threaded section is provided on the positioning rod 4, and the handle 5 is threadedly connected to the positioning rod 4. The staff rotates the handle 5 to move it downward along the threaded section of the positioning rod 4, and the bottom of the handle 5 enters the accommodating section 301 of the positioning hole 3. Since the bottom width of the handle 5 is greater than the minimum width on the limiting section 302 of the positioning hole 3, the handle 5 cannot fall off from the limiting section 302 of the positioning hole 3; compared with the prior art in which the screw rod needs to be completely screwed into the screw hole, the handle 5 in the present embodiment only needs to make its bottom part enter the accommodating section 301 of the positioning hole 3 to complete the limiting and realize the fixation of the cover plate 2; compared with the prior art, the operation is simple, the manual workload is small, the cover plate 2 is easy to open and close, and it is convenient to check the material status in the raw material tank at any time, improve the working efficiency, and greatly shorten the operation time.

[0029] In other embodiments, the positioning rod 4 is a telescopic structure, and the staff adjusts the telescopic length of the positioning rod 4 to make the bottom of the handle 5 enter the accommodating section 301 of the positioning hole 3, thereby quickly completing the limiting.

[0030] See also Figure 3 , is a schematic diagram of the structure of the utility model from another angle. Furthermore, the positioning holes 3 are evenly distributed along the edge of the cover plate 2, and the positioning rods 4 exert a uniform force on the cover plate 2.

[0031] Furthermore, the number of the positioning holes 3 and the number of the positioning rods 4 are both three, which are distributed in an equilateral triangle, thereby optimizing the number of screw holes and screw rods in the prior art and improving the sealing and stability of the cover plate 2 to the raw material tank.

[0032] Furthermore, the cover plate 2 is provided with a viewing window 6 to facilitate observation by staff.

[0033] This embodiment provides a raw material tank cover that is easy to install and disassemble, wherein a base 1 is arranged on the tank body, a through hole is connected to the inside of the tank body, and materials enter or leave the inside of the tank body through the through hole on the base 1.

[0034] The usage method of the utility model is as follows: when it is necessary to open the cover plate 2 of the raw material tank, the staff rotates the handle 5 to move it up along the positioning rod 4, the handle 5 leaves the accommodating section 301 of the positioning hole 3, rotates the positioning rod 4 to leave the positioning hole 3, and the cover plate 2 is opened; when the use is completed and the cover plate 2 of the raw material tank needs to be closed, the staff rotates the positioning rod 4 to make it enter the positioning hole 3, rotates the handle 5 in the opposite direction to make it move down along the positioning rod 4 until the bottom of the handle 5 enters the accommodating section 301 of the positioning hole 3, the bottom of the handle 5 cooperates with the accommodating section 301 of the positioning hole 3, and the limiting section 302 of the positioning hole 3 limits the handle 5 so that it will not fall off from the positioning hole 3, thereby completing the closing of the cover plate 2.

[0035] In the utility model, when closing the raw material tank cover 2, the staff rotates the positioning rod 4 to make it enter the positioning hole 3, and the handle 5 moves down along the positioning rod 4 to cooperate with the accommodating section 301 of the positioning hole 3. The limiting section 302 of the positioning hole 3 limits the handle 5 so that it will not fall off from the positioning hole 3. Compared with the prior art, the operation is simple, the manual workload is small, the cover 2 is easy to open and close, and it is convenient to check the material status in the raw material tank at any time, improve the working efficiency, and greatly shorten the operation time. The positioning rod 4 is set on the base 1, which is not easy to lose, and the staff does not need to be distracted to store the positioning rod 4. A visual window 6 is provided on the cover 2 for the staff to observe.
