The lower conical surface 403 rotates with the inner turntable 4 to further mix the grain sample, and the mixed grain sample falls into the discharge box 201.

[0007] The outlet of the discharge channel 102 is arranged in the base platform 2 , and a discharge box 201 is arranged in the base platform 2 . The outlet of the discharge channel 102 is above the discharge box 201 , and a handle 202 is arranged on the discharge box 201 .

The inner turntable 4 is driven by the motor to rotate, and the rice sample enters the upper part of the inner turntable 4 through the feeding channel 101, and the grain sample passes and is mixed by the gap between the side surface 401 on the inner turntable 4 and the inner wall of the turntable shell. The inner turntable 4 is driven to rotate by the motor 5, and the grain sample is mixed inside and enters the discharging channel 102 to fall into the inlet and outlet box 201 to complete the mixing.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model is provided with an inner turntable, which is driven to rotate by a motor when in use. The sample grains are first rotated and mixed on the upper surface of the inner turntable, and then further mixed through the gap channel between the side surface and the lower cone surface of the inner turntable and the outer shell of the turntable. During the rotation of the inner turntable, different sample grains are rotated and mixed in the gap channel, and the rotating inner turntable also drives the grain samples in the channel to rotate and mix, and enter the discharge box through the channel to complete the mixing. Through the rotation and mixing on the turntable and in the channel, a variety of sample grains can be better mixed and better tested. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to clarify the technical problems, technical solutions, implementation processes and performance demonstrations, the utility model is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are for explanation only. The utility model is not intended to limit the utility model. Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same figure numbers in the drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0021] like Figure 1-Figure 6 As shown, a laboratory sample mixer comprises a turntable housing 1, a base platform 2, a motor housing 3, an inner turntable 4 and a motor 5, the inner turntable 4 is provided with a side surface 401 on the side, a groove 402 is provided on the side surface 401, an upper conical platform 404 is provided above the inner turntable 4, and a lower conical surface 403 is provided below the inner turntable 4, the inner turntable 4 is arranged in the turntable housing 1, the motor housing 3 is provided above the turntable housing 1, the base platform 2 is provided below, and the motor 5 is provided in the motor housing 3.

[0022] The turntable shell 1 is provided with a plurality of feeding channels 101, a gap exists between the side surface of the inner turntable 4 and the turntable shell 1 for the sample grain to pass through, and the lower conical surface 403 on the inner turntable 4 and the inner wall of the turntable shell 1 form a discharge channel 102. The lower conical surface 403 rotates with the inner turntable 4 to further mix the grain sample, and the mixed grain sample falls into the discharge box 201.

[0023] The outlet of the discharge channel 102 is arranged in the base platform 2 , and a discharge box 201 is arranged in the base platform 2 . The outlet of the discharge channel 102 is above the discharge box 201 , and a handle 202 is arranged on the discharge box 201 .

[0024] The motor 5 is provided with a rotating shaft 501, and the other end of the rotating shaft 501 is connected to the inner turntable 4. The inner turntable 4 is driven by the motor to rotate, and the rice sample enters the upper part of the inner turntable 4 through the feeding channel 101, and the gap between the side surface 401 on the inner turntable 4 and the inner wall of the turntable shell is used to pass and mix the grain sample. The inner turntable 4 is driven by the motor 5 to rotate, and the grain sample is mixed inside and enters the discharging channel 102 to fall into the inlet and outlet box 201 to complete the mixing. With the rotation of the inner turntable 4, the grain sample passes through the channel between the turntable 4 and the turntable shell 1, and various grains are gradually mixed evenly. The continuous rotation of the inner turntable 4 will not cause the grain to be blocked in the channel.

[0025] When in use, various grain samples are put in through the feed channel 101, and then the motor 5 is driven. The motor 5 drives the inner turntable 4 to rotate through the rotating shaft 501.
