[0014] In order to fully understand the purpose, features and effects of the utility model, the utility model is described in detail by the following specific embodiments, but the utility model is not limited to this.

[0015] As Figures 1 to 3 shown, the utility model provides a kind of mortar structure of grinding machine, including outer cylinder body 1, upper sealing plate 2, lower sealing plate 3, mortar, tray 10 and discharging pipe 7, the upper and lower ends of outer cylinder body 1 are respectively fixedly connected with upper sealing plate 2, lower sealing plate 3, lower sealing plate 3 is used as material bowl vibration table, material bowl vibration table is installed on the support frame inside machine body by vibration spring, lower sealing plate 3 lower part is equipped with eccentric drive device, the eccentric drive device is prior art, not shown in the figure, not detailedly described here.

[0016] The cavity of the outer cylinder 1 is internally provided with a mortar, which comprises a core body 11 and a ring body 9. The ring body 9 is a cylindrical structure with open upper and lower ends, and the upper end surface of the ring body 9 is fixedly connected with the inner surface of the upper cover plate 2, while the lower end surface of the ring body 9 is suspended. The core body 11 is located in the ring body 9 and is placed on the tray 10 and is only supported on the tray 10 without other connection forms. The outer circle of the tray 10 is fixedly connected with the end of the telescopic rod 8 of the air cylinder 4, the telescopic cylinder 8 is located outside the ring body 9, and the air cylinder 4 is fixed on the upper surface of the upper cover plate 2. Preferably, the number of air cylinders 4 is three or four, which are arranged in a ring shape and are uniformly distributed. The position of the telescopic rod 8 penetrating through the upper cover plate 2 is provided with a sealing ring to ensure the sealing of the mortar. The telescopic range of the end of the telescopic rod 8 is controlled to be 1-2 cm. Preferably, a ring-shaped limiting groove is formed in the upper surface of the tray 10. When the telescopic rod 8 is lifted and the mortar is sealed, the lower end surface of the ring body 9 is clamped in the ring-shaped limiting groove, thereby improving the sealing performance of the mortar.

[0017] A feeding port is formed in the center of the upper cover plate 2, and a feeding pipe 5 is fixedly connected with the feeding port. The feeding pipe 5 feeds the material to be ground into the mortar. A blowing port is also formed near the feeding port of the upper cover plate 2, and a nozzle is arranged at the blowing port. The nozzle is inclinedly arranged, and the lower edge of the nozzle does not exceed the lower surface of the upper cover plate, so as to avoid the damage of the nozzle caused by the impact of the core body of the mortar. The nozzle is connected with a high-pressure gas source through an air inlet pipe 6. Preferably, the nozzle is inclinedly arranged at an angle of 45°, and the nozzle is inclined toward the end of the discharge pipe. In some preferred embodiments, the upper cover plate 2 outside the ring body 9 is also provided with inclined nozzles, which can protrude to the lower side of the upper cover plate 2 to blow away the floating material on the discharge bottom plate 12 and the tray 10.

[0020] The telescopic rod 8 is retracted by the air cylinder 4, and the tray 10 is lifted. At this time, the tray 10 and the ring body 9 form a closed grinding space. The material to be ground is fed into the grinding space through the feeding pipe 5. The eccentric driving device is started to make the device eccentrically vibrate. The core body 11 vibrates and impacts the material to be ground in the grinding space, so as to grind the material into powder. After grinding is completed, the eccentric vibration is still maintained. The telescopic rod 8 is extended by the air cylinder 4, the tray 10 is lowered, and the gap for discharging the powder sample is generated between the ring body 9 and the tray 10. The nozzle intermittently sprays high-pressure gas into the mortar and on the discharge bottom plate, so as to spray the ground sample into the discharge pipe 7. The sample is discharged along the discharge pipe 7, the outlet of the discharge pipe 7 is placed on the sample bucket, and the sample grinding operation is completed.
