Rotary division machine

Abstract

The invention discloses a rotary division machine which comprises a material containing mechanism arranged at the top of a rack and a uniform feeding mechanism arranged below the material containing mechanism. A material guiding mechanism is arranged below the uniform feeding mechanism and used for equally dividing a sample material, the material guiding mechanism comprises a rotating disc arranged below a top plate of the rack and a plurality of material guiding pipes uniformly distributed below a material inlet of the rotating disc in the same circle, and a main power mechanism is in transmission connection with the material guiding mechanism; and a bottle placing and material receiving mechanism is arranged below the material guiding mechanism. The rotary division machine is characterized in that a gate mechanism is arranged at outlets of the material guiding pipes, the gate mechanism comprises a movable door capable of being opened in a turnover mode and a spring connected with the movable door and used for keeping the movable door at the closed position, and a door opening mechanism is arranged near the material guiding pipes corresponding to a sample unloading position. The problems that a bottle placing and sample receiving mechanism of an existing division machine is complex in structure and cannot unload samples at a fixed position are solved, the material guiding mechanism can temporarily store the samples to the designated position to unload the samples, and the bottle placing and sample receiving mechanism is more suitable for automatic operation.

Description

technical field [0001] The invention relates to a rotary shrinking machine for sample preparation, in particular to a rotary shrinking machine with temporary storage and automatic cleaning functions, belonging to the field of coal sampling and sample preparation. Background technique [0002] In the field of ore sample preparation, shrinkage devices are used for sample preparation, and there are many types of shrinkage devices. Among them, the rotary shrinkage machine has a high utilization rate due to the smallest qualitative error in the shrinkage process. [0003] The problems of the general rotary shrinking machine are: first, because the robot needs to directly place the bottle on the rotating platform, therefore, there must be a gap between the upper port of the sample bottle and the outlet of the guide tube. When shrinking, Dust will overflow from the gap; second, the material receiving barrel cannot enter and exit automatically, and needs to be held by the clamping f...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that in the prior art, the rotary shrinking machine cannot temporarily store samples, and several material guide pipes unload samples at the same time, so that the samples cannot be unloaded at a fixed sample unloading position, and the structure of the bottle placing mechanism is complicated.

[0008] Another object of the present invention is to solve the problem that the existing rotary shrinking machine cannot self-clean the material guide mechanism, and cross-contamination of samples from different batches affects the purity of the samples
