[0011] In a preferred example, the present invention can be further configured as follows: the hopper is clamped to the bottom of the conveying barrel, and the diameter of the top of the hopper is larger than the diameter of the conveying barrel.

[0012] In a preferred example, the present invention can be further configured as follows: the inner ends of the two material distribution pipes are flush with the inner wall of the hopper, and the outer wall of the blocking column is movably fitted with the inner ends of the two material distribution pipes.

[0014] In the utility model, raw materials are injected into the conveying barrel through the feed port, and then the motor is started, and then the screw rod makes the raw materials slide into the hopper. Then the staff starts the cylinder according to the processing capacity of the vertical mill body, and then the movable end of the cylinder descends with the blocking column. The descending amplitude of the blocking column determines the speed of the raw materials flowing out of the two distribution pipes. When the raw materials ground by the vertical mill body become worse, the movable end of the cylinder is controlled to extend until the vertical mill body grinds the powdered raw materials stably. The mechanical properties of the vertical mill body can be accurately measured to improve the grinding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0023] A combined feeding and discharging vertical mill provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] Example 1:

[0025] Combine Figure 1-3 As shown, the utility model provides a combined feeding and discharging vertical mill, including a feeding mechanism 100 and a quantity control mechanism 200. The feeding mechanism 100 includes a vertical mill body 110, two supports 120 provided on one side of the vertical mill body 110, a conveying barrel 130 connected between the two supports 120, a screw rod 140 movably installed inside the conveying barrel 130, and a motor 150 connected between the conveying barrel 130 and the screw rod 140. A feed port is provided on the top of the conveying barrel 130.

[0026] The quantity control mechanism 200 includes a bracket 210 provided between the vertical mill body 110 and the conveying barrel 130, a hopper 220 connected to the top of the bracket 210, a blocking column 230 slidably installed inside the hopper 220, a cylinder 240 connected between the bracket 210 and the blocking column 230, and two distribution pipes 250 connected and communicated with the hopper 220, and both distribution pipes 250 are communicated with the feed end of the vertical mill body 110.

[0027] Furthermore, the two supports 120 are vertically symmetrical about the vertical center plane of the conveying barrel 130. The supports 120 are arranged in a U shape. With this layout design, the conveying barrel 130 can be erected horizontally and stably.

[0028] Furthermore, the feed port is close to the motor 150 and is connected to the interior of the conveying barrel 130. With this layout design, the raw materials can enter the interior of the conveying barrel 130 to achieve the purpose of smooth feeding.

[0029] Furthermore, the inner ends of the two distribution pipes 250 are flush with the inner wall of the hopper 220, and the outer wall of the blocking column 230 is movably fitted with the inner ends of the two distribution pipes 250. With this structural design, the blocking column 230 can be flexibly raised and lowered, and then the opening degree of the two distribution pipes 250 can be controlled, providing conditions for controlling the discharge speed of the distribution pipes 250.

[0030] Example 2:

[0031] Combine Figure 1-3 As shown, based on the first embodiment, the motor 150 is connected in series with the vertical mill body 110, and the motor 150 is electrically connected to the external power supply. This structural design improves the user comfort of the device.

[0032] Example 3:

[0033] Combine Figure 1 and Figure 3 As shown, in the above embodiment, the hopper 220 is clamped to the bottom of the conveying barrel 130, and the top diameter of the hopper 220 is larger than the diameter of the conveying barrel 130. With this size design, the raw materials in the conveying barrel 130 can completely fall into the inside of the hopper 220.

[0034] The working principle and use process of the present invention are as follows: when the device is put into actual use, raw materials are injected into the conveying barrel 130 through the feed port, and then the motor 150 is started, and then the screw rod 140 makes the raw materials slide into the hopper 220, and then the staff starts the cylinder 240 according to the processing capacity of the vertical mill body 110, and then the movable end of the cylinder 240 descends with the blocking column 230, and the descending amplitude of the blocking column 230 determines the speed of the raw materials flowing out of the two distribution pipes 250. When the raw materials ground out of the vertical mill body 110 become worse, the movable end of the cylinder 240 is controlled to extend until the vertical mill body 110 stably grinds out the powdered raw materials. The mechanical properties of the vertical mill body 110 can be accurately measured to improve the grinding efficiency.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
