Description

Technical Field

[0001] The utility model relates to a soil configuration combined device, in particular to a combined device used for configuring laboratory potted soil, belonging to the technical field of soil configuration equipment. Background Art

[0002] In potted plant experiments and flower garden soil and matrix soil configuration, each flower pot uses a small amount of soil, but the accuracy of the conditions such as the particle size and nutrient ratio of the potted soil is required to be high. Therefore, when configuring experimental soil or flower soil, it is necessary to collect the original soil from the field and sieve it, and then add matrix soil, vermiculite, fertilizer, fine sand and other materials according to actual needs and mix them evenly. In order to improve the configuration efficiency, it is often necessary to use corresponding devices for auxiliary configuration.

[0003] In the prior art, for example, a nutrient soil preparation device disclosed in announcement number CN219330258U adds a containing box and a containing bag, so that the ingredients can be conveniently poured into the containing bag for preparation. After the preparation is completed, the containing bag can be taken out and poured into a culture plate, or the containing bag can be directly placed in a flower pot or a culture plate. However, for the prior art, although the configuration of precise proportions can be achieved, when configuring the experimental soil, the soil screening, stirring, and filling processes are basically mainly manual operations. When configuring a large amount of potting soil, not only will the work intensity be high and the work efficiency be low, but also the stirring process will be very labor-intensive. Uneven stirring often occurs during the process, which affects the experiment. In addition, for the prior art, such as a soil stirring device disclosed in announcement number CN213556452U and a soil screening device disclosed in announcement number CN114260182A, although the soil can be stirred or screened separately, the prior art cannot realize the process-based configuration of the entire configuration process, that is, the screened soil needs to be taken out and then poured into the stirring device, which brings more inconvenience to the entire configuration process, increases the workload of personnel, and reduces work efficiency.
