Description

Technical Field

[0001] The invention relates to the technical field of vegetable cultivation equipment, in particular to a pepper sprout cultivation equipment. Background Art

[0002] Sprouts, also known as bean sprouts, are edible small "sprouts" grown from various bean seeds, cereal seeds, and tree seeds through artificial cultivation, that is, the tender seedlings that have just grown from the seeds. At present, there are relatively few varieties of sprouts commonly seen on the market, with pea sprouts and radish sprouts being the most common. In fact, other sprouts that can be cultivated include pepper sprouts, asparagus bean sprouts, sunflower seed sprouts, broad bean sprouts, buckwheat sprouts, toon sprouts, peanut sprouts, etc.

[0003] In the prior art, the sprout cultivation equipment on the market often adopts a spraying water supply method. For example: Application No. CN202110128349.3 discloses a self-controlled intelligent sprout growth and cultivation equipment. In this scheme, a spray mechanism is used to realize continuous spraying water supply to the cultivation unit in a rotating state. However, in the sprout cultivation stage, the continuous spraying water supply method will cause water droplets to occupy the leaf surface of the sprouts for a long time. On the one hand, the photosynthesis of the sprouts is restricted to varying degrees, so that the growth of the sprouts is slowed down. On the other hand, it will cause a large amount of water to accumulate in the roots of the sprouts, causing root rot, which is not conducive to the efficient cultivation of sprouts.

At the same time, by opening the valve end of the carbon dioxide storage tank 9, the water in the cultivation bucket 7 is discharged. , which promotes the carbon dioxide gas to pass from the gas supply pipe 10 into the several shunt pipes 12 on its surface. Since each shunt pipe 12 is connected to a U-shaped pipe 5, and the part of the U-shaped pipe 5 extending to the cultivation chamber 3 is evenly spaced with several gas supply elbows 27, during the pepper sprout cultivation stage, the gas supply elbow 27 of each U-shaped pipe 5 can supply carbon dioxide to the cultivation bucket 7 in the cultivation chamber 3, and continuously provide nutrients for the cultivation of pepper sprouts. At this time, the carbon dioxide sensor 23 built into the cultivation basket 18 can detect the carbon dioxide concentration data of its installation position in real time, and feed it back to the PLC controller 11 in the form of an electrical signal. When the detected carbon dioxide concentration exceeds the preset value range of the PLC controller 11, the PLC controller 11 closes the electric valve 13 set at the cultivation chamber 3 to avoid the situation where the photosynthesis of the pepper sprouts is stopped due to the high carbon dioxide concentration. When the pepper sprout cultivation is completed, the cultivation bucket 7 and the liquid supply box 6 in the cultivation chamber 3 are taken out, and the pepper sprouts can be harvested.
