Description

Technical Field

[0001] The utility model relates to the technical field of soilless cultivation, in particular to a mixing device for soilless cultivation substrates. Background Art

[0002] Soilless cultivation refers to a cultivation method that uses water, peat, forest leaf mold, vermiculite and other media as the substrate for the plant roots to fix the plants, so that the plant roots can directly contact the nutrient solution. The composition of the nutrient solution in soilless cultivation is easy to control and can be adjusted at any time. The substrate is very important in soilless cultivation. It uses a solid substrate to fix the plant roots and absorbs nutrient solution and oxygen through the substrate to support plant growth. Compared with traditional soil cultivation, this cultivation method has many advantages, such as simple equipment, low production cost, and better control of the composition and proportion of the nutrient solution. The substrate for soilless cultivation can be divided into two categories: inorganic substrate and organic substrate. Multiple substrates need to be mixed before using them.

[0003] The existing soilless cultivation substrate mixing device includes a mixing box, and multiple substrates can be placed in the mixing box for stirring. However, the mixing of the substrates requires a certain ratio. The existing device requires the substrates to be weighed in advance and then introduced into the mixing box. The quantitative measurement is inaccurate and the efficiency is low. These problems will affect the growth and yield of the plants. In addition, the amount of the mixed substrate cannot be controlled according to the needs when it is used. Too much substrate will be wasted. Therefore, a soilless cultivation substrate mixing device that can quantitatively load and unload materials is needed. Utility Model Content

A feeding chamber is located at the bottom end of the second partition plate, and the feeding pipe extends into the medicine chamber. A second metering barrel connected to the mixing chamber is provided on the left outer wall of the mixing barrel. The stirring rod is located in the mixing chamber. A stirring motor for driving the stirring rod is fixedly provided on the bottom surface of the second partition plate. A feeding barrel is horizontally provided in the feeding chamber.
