[0041] like Figure 1-6 As shown, a vertical grinding machine comprises:

[0042] Base 1, driving assembly 2, screw assembly 3, rotating shaft 4, grinding disc assembly 5;

[0043] A mounting seat 11 is provided at the upper end of the base 1;

[0044] The drive assembly 2 is connected via a mounting seat 11;

[0045] The screw assembly 3 is arranged on the upper part of the mounting seat 11, and one end of the rotating shaft 4 is rotatably connected to the end of the screw assembly 3;

[0046] The other end of the rotating shaft 4 is connected to the grinding disc assembly 5;

[0047] The output end of the driving assembly 2 is drivingly connected to the rotating shaft 4;

[0048] The grinding disc assembly 5 includes a mounting disc 51, a first grinding disc 52, a second grinding disc 53, a feed portion 54, and a hopper 55;

[0049] The feed portion 54 is located at the upper end of the mounting plate 51, and the first grinding plate 52 is connected to the lower end of the mounting plate 51;

[0050] The second grinding disc 53 is connected to the rotating shaft 4 and fits under the first grinding disc 52;

[0051] The hopper 55 is connected to the mounting plate 51 and is fitted under the second grinding plate 53 .

[0052] Specifically, when grinding, the material is put in through the feed part 54, and the material will enter between the first grinding disc 52 and the second grinding disc 53. The drive assembly 2 can drive the shaft 4 to rotate, thereby driving the second grinding disc 53 to rotate, and cooperate with the first grinding disc 52 to complete the grinding. The screw assembly 3 can make the shaft 4 move up and down, thereby driving the second grinding disc 53 to move, so that the spacing between the first grinding disc 52 and the second grinding disc 53 can be adjusted, and the grinding spacing can be adjusted, so as to facilitate precise adjustment to achieve excellent grinding results and avoid multiple grinding operations in order to achieve the required mesh number of particles. The feed part 54 is open, which is convenient for the feeding of materials and cleaning, and can prevent material splashing back to protect the safety of experimenters.

[0053] In some embodiments, the drive assembly 2 includes a motor 21, a pulley 22, a belt 23, and a transmission shaft 24;

[0054] The output end of the motor 21 is connected to the pulley 22 via a belt 23;

[0055] One end of the transmission shaft 24 is connected to the pulley 22, and the other end is in transmission cooperation with the rotating shaft 4 through a gear.

[0056] The rotating shaft 4 is provided with a shaft sleeve 41, and the shaft sleeve 41 is provided with a helical gear 42;

[0057] The transmission shaft 24 and the shaft sleeve 41 are coupled to each other through the bevel gear 42 .

[0058] With the above technical solution, the motor 21 drives the pulley 22 to rotate through the belt 23, and further drives the transmission shaft 24 to rotate. With the cooperation of the bevel gear 42, the sleeve 41 can rotate with the rotating shaft 4 to perform the grinding operation. It should be noted that the sleeve 41 and the rotating shaft 4 are limited in the axial direction, but not in the axial direction, which allows the rotating shaft 4 to rotate with the sleeve 41 while maintaining the upward and downward movement adjustment.

[0059] In some embodiments, the screw assembly 3 includes a screw 31 and an adjusting member 32;

[0060] The adjusting member 32 and the screw rod 31 are threadedly engaged.

[0061] By adopting the above technical solution, the screw rod 31 can be adjusted up and down by rotating the adjusting member 32, thereby driving the rotating shaft 4 to adjust up and down, so as to achieve the purpose of adjusting the distance between the first grinding disc 52 and the second grinding disc 53. Optionally, the adjusting member 32 can be a plum blossom nut, which is convenient for personnel to rotate and adjust. It should be noted that the screw rod 31 is a conventional screw rod, so the thread expression is omitted in the attached figure.

[0062] In some embodiments, Figure 6 As shown, the end of the screw rod 31 and the end of the rotating shaft 4 are provided with a connecting assembly 6;

[0063] The connecting assembly 6 includes a rotating drum 61, a connecting head 62, and a bearing 63;

[0064] One end of the rotating drum 61 is connected to the rotating shaft 4 , and the other end is matched with the connecting head 62 through the bearing 63 . The connecting head 62 passes through and is connected to the screw rod 31 .

[0065] By adopting the above technical solution, the rotating drum 61 can be connected to the rotating shaft 4 through a nut, so that the rotating drum 61 can rotate together when the rotating shaft 4 rotates, and the connecting head 62 can be stably connected to the screw rod 31. With the cooperation of the bearing 63, the connecting head 62 will not rotate, thereby maintaining the stability of the screw rod 31.

[0066] In some embodiments, a locking portion 511 is provided on the side of the mounting plate 51;

[0067] The side of the hopper 55 is provided with a protrusion 551;

[0068] The protrusion 551 is matched with the locking portion 511 .

[0069] By adopting the above technical solution, after being assembled in place, the protrusion 551 is inserted into the groove of the locking part 511, so that the hopper 55 is stably connected to the mounting plate 51. After the grinding is completed, the hopper 55 can be rotated to allow the protrusion 551 to be disengaged from the groove of the locking part 511, so that the hopper 55 can be removed, which is convenient for taking out the ground material and convenient for cleaning the mounting plate 51, the first grinding plate 52, the second grinding plate 53, and the feeding part 54.
