[0026] See also Figures 1 to 3 As shown, the grinding jar 1 provided by the present invention includes a jar body 11, a cover body 12 and a grinding body 13. The jar body 11 includes a conical cylinder 111, the bottom of the conical cylinder 111 is hemispherical, and the surface of the conical cylinder 111 away from the bottom is concave to form a receiving cavity 112, which is used to receive the sample to be ground.

[0027] The cover body 12 includes a cylinder cover 121 . The cylinder cover 121 is disposed at the opening of the accommodating cavity 112 . The cylinder cover 121 is connected to the conical cylinder 111 to close the accommodating cavity 112 .

[0028] The grinding body 13 includes a grinding rod 131 and a shaft 132. The shaft 132 is rotatably provided on the cover body 12. The shaft 132 extends toward the bottom of the conical cylinder 111. One end of the grinding rod 131 is connected to the extended end of the shaft 132, and the other end extends along the side wall of the accommodating cavity 112 toward the cylinder cover 121. The shaft 132 can be rotated under force and drive the grinding rod 131 to rotate to grind the sample.

[0029] The grinding jar 1 provided in this embodiment is configured such that the bottom of the conical cylinder 111 is hemispherical and the bottom of the conical cylinder 111 faces downward, so that the sample moves toward the bottom of the conical cylinder 111 under gravity during the grinding process; and the grinding jar 1 extends toward the bottom of the conical cylinder 111 through the shaft 132, and the grinding rod 131 is connected to the end of the extension of the shaft 132, so that the grinding rod 131 can grind the sample located at the bottom of the conical cylinder 111, and the grinding rod 131 extends along the side wall of the accommodating chamber 112 toward the cylinder cover 121, thereby further grinding the sample in the accommodating chamber 112, so that the sample in the accommodating chamber 112 is fully ground to improve the grinding efficiency of the grinding jar 1.

[0030] In this embodiment, the grinding rod 131 is cylindrical, and one end of the grinding rod 131, located near the bottom of the conical barrel 111, is hemispherical. This allows the grinding rod 131 to fit snugly against the bottom of the conical barrel 111, allowing it to grind samples located at the bottom of the conical barrel 111. The circumference of the grinding rod 131 aligns with the wall of the conical barrel 111, and the sample is ground due to friction between the surfaces of the grinding rod 131 and the conical barrel 111.

[0031] As a further improvement of this embodiment, a plurality of grinding rods 131 are provided, and the plurality of grinding rods 131 are distributed around the shaft 132 .

[0032] In this embodiment, the grinding body 13 is provided with a plurality of grinding rods 131 to grind the sample simultaneously, thereby improving the efficiency of the grinding jar 1 in grinding the sample.

[0033] As a further improvement of this embodiment, the barrel cover 121 is provided with a through hole 122, which is connected to the accommodating cavity 112. One end of the shaft 132 is provided on the side of the barrel cover 121 away from the accommodating cavity 112, and the other end extends through the through hole 122 to the accommodating cavity 112.

[0034] In this embodiment, the end of the shaft 132 away from the accommodating chamber 112 is connected to a driving device, which is used to provide torque to rotate the shaft 132, thereby driving the grinding rod 131 to rotate in the accommodating chamber 112. It is understandable that the driving device can be a motor or the like.

[0035] As a further improvement of this embodiment, the grinding jar 1 further includes a grinding cover 14 , which is disposed on the cylinder cover 121 and protrudes from the cylinder cover 121 toward the grinding rod 131 . The grinding rod 131 is disposed between the grinding cover 14 and the conical cylinder 111 .

[0036] In this embodiment, the grinding cover 14 corresponds to the grinding rod 131 on one side surface opposite to the conical cylinder 111. The grinding rod 131 stirs the sample so that the sample moves and rubs against the surface of the grinding cover 14 and the surface of the grinding rod 131 for grinding, thereby improving the grinding efficiency of the grinding jar 1.

[0037] As a further improvement of this embodiment, the grinding cover 14 is hollow and connected to the cylinder cover 121 to enclose a first chamber 141. The grinding cover 14 and the conical cylinder 111 enclose a second chamber 142. The grinding cover 14 is provided with a grinding hole 143, which connects the first chamber 141 and the second chamber 142.

[0038] In this embodiment, the grinding cover 14 divides the accommodating chamber 112 into a first chamber 141 and a second chamber 142. The sample to be ground is first placed in the second chamber 142. The shaft 132 rotates and drives the grinding rod 131 to rotate, so that the sample rubs against the surfaces of the grinding cover 14 and the grinding rod 131, thereby grinding the sample.

[0039] The diameter of the grinding hole 143 is set to the target grinding diameter, so that the grinding cover 14 filters out samples with a diameter smaller than the grinding hole 143. Samples with a diameter smaller than the grinding hole 143 in the second chamber 142 pass through the grinding hole 143 into the first chamber 141, while samples with a diameter larger than the grinding hole 143 continue to be ground in the second chamber 142. This configuration allows all samples to be ground to a diameter smaller than the grinding hole 143, ensuring that the samples in the accommodating chamber 112 are fully ground, thereby improving the grinding efficiency of the grinding jar 1.

[0040] As a further improvement of this embodiment, a funnel opening 144 is formed at the bottom of the grinding cover 14 , and the shaft 132 passes through the funnel opening 144 .

[0041] In this embodiment, the sample in the first chamber 141 returns to the second chamber 142 from the funnel mouth 144 under the action of gravity, and the sample rubs against the surface of the grinding rod 131 and the surface of the conical cylinder 111 for further grinding. The sample is ground back and forth in the second chamber 142 and the first chamber 141, so that the sample in the accommodating chamber 112 is fully ground, thereby improving the grinding efficiency of the grinding jar 1.

[0042] As a further improvement of this embodiment, the grinding cover 14 is detachably connected to the cylinder cover 121 via threads.

[0043] In this embodiment, the grinding cover 14 has a threaded end away from the bottom. The grinding cover 14 is located in the middle of the cylinder cover 121 and is connected to the cylinder cover 121 via a threaded connection. The cylinder cover 121 can be installed without the grinding cover 14, so that the sample is ground by friction with the surface of the grinding rod 131 and the surface of the conical cylinder 111. The cylinder cover 121 can be installed with the grinding cover 14, so that the sample can be ground not only by friction with the surface of the grinding rod 131 and the surface of the conical cylinder 111, but also by friction with the surface of the grinding rod 131 and the surface of the grinding cover 14.

[0044] As a further improvement of this embodiment, the cover body 12 further includes a sealing ring 123 , which is disposed between the cylinder cover 121 and the conical cylinder 111 .

[0045] In this embodiment, the cylinder cover 121 seals the conical cylinder 111 through the sealing ring 123 , thereby reducing the leakage of the sample from the conical cylinder 111 and improving the grinding efficiency of the grinding jar 1 .

[0046] As a further improvement of this embodiment, the tank body 11 further includes a bracket 113 . The bracket 113 is connected to the bottom wall of the conical cylinder 111 . The bracket 113 is used to support the conical cylinder 111 .

[0047] In this embodiment, the bracket 113 is used to support the conical cylinder 111 to improve the stability of the conical cylinder 111 during the grinding process, so that the shaft 132 drives the grinding rod 131 to rotate stably in the conical cylinder 111 to improve the grinding efficiency of the grinding jar 1.

[0048] In summary, the grinding jar 1 provided by the present invention is connected to the end of the extension of the shaft 132 via the grinding rod 131, so that the grinding rod 131 can grind the sample located at the bottom of the conical barrel 111, and the grinding rod 131 extends along the side wall of the accommodating chamber 112 toward the barrel cover 121, thereby further grinding the sample in the accommodating chamber 112, so that the sample in the accommodating chamber 112 is fully ground, thereby improving the grinding efficiency of the grinding jar 1. The grinding jar 1 is provided with a grinding cover 14, and the grinding rod 131 is provided between the grinding cover 14 and the conical barrel 111. The sample is not only ground between the grinding rod 131 and the conical barrel 111, but also between the grinding rod 131 and the grinding cover 14, so that the sample in the accommodating chamber 112 is fully ground, thereby improving the grinding efficiency of the grinding jar 1.
