Multifunctional agricultural material suspension speed test device

Abstract

The invention relates to a multifunctional agricultural material suspension speed test device, which comprises at least one group of testing units. Each testing unit comprises a collecting pipe, a rectifying pipe, a feeding pipe, a first steady flow straight pipe and a conical testing pipe which are sequentially connected from bottom to top; the first steady flow pipe is vertically provided with afirst test hole along the side surface of the pipe wall; a second test hole is vertically formed in the conical test tube along the side surface of the tube wall; the number of the first test holes and the number of the second test holes are both not less than 3, and it is guaranteed that at least one test hole is correspondingly formed in the top side, the middle and the bottom side of the pipewall; the caliber of the conical test tube is small at the lower part and large at the upper part; the top of the conical test tube is connected with a second steady-flow straight tube; the top of thesecond steady flow straight pipe is connected with a diffusion cover; and the first steady flow straight pipe, the conical test pipe and the second steady flow straight pipe are all transparent pipes. According to the multifunctional agricultural material suspension speed test device disclosed by the invention, various tests on materials can be realized; the test is visual and can be observed clearly, and test data can be collected and analyzed conveniently.

Description

technical field [0001] The invention relates to the field of testing the suspension speed of agricultural materials, in particular to a multifunctional testing device for the suspension speed of agricultural materials. Background technique [0002] The existing agricultural material suspension velocity testing device can realize the measurement of material suspension velocity, but has the following disadvantages: [0003] 1. There are too few measuring holes, which is insufficient for the research and improvement of the wind speed uniformity of the test device. [0004] 2. Basically, it can only measure the suspension speed of the material, but it is not suitable to measure the separation wind speed of the mixed material. [0005] 3. It is not convenient for more intuitive and clear observation, comparative research and analysis of the conveying and moving state of materials in fixed-diameter pipelines under different volume fractions. Contents of the invention [0006] ...
