Accurate seed dropping device for vegetable seedling culture

Abstract

The invention belongs to the technical field of agricultural planting, and particularly relates to an accurate seed dropping device for vegetable seedling culture. The accurate seed dropping device comprises a plurality of vegetable seedling culture trays, and each seedling culture tray is provided with a plurality of containing grooves. The accurate seed dropping device comprises a soil laying device, a seed dropping device, a vermiculite laying device and a control device. The soil laying device comprises a soil laying assembly, a first rolling-out assembly, a groove pressing assembly and afirst conveying belt. The seed dropping device comprises a containing assembly, a seed sucking assembly, a lifting assembly and a second conveying belt. The vermiculite laying device comprises a vermiculite laying assembly, a second rolling-out assembly and a third conveying belt. The control device comprises a controller and a sensor assembly electrically connected with the controller. Manual operation is completely omitted in the whole process, full-automatic seedling culture production is realized, the production efficiency is improved, and unnecessary cost waste is avoided.

Description

Technical field [0001] The invention belongs to the technical field of agricultural planting. Specifically, the invention relates to a precise planting device for vegetable seedlings. Background technique [0002] Nursery is the meaning of cultivating seedlings. The original meaning refers to the cultivation of seedlings in nurseries, hotbeds or greenhouses for transplanting to the ground for planting. It can also refer to the stage where various organisms have been artificially protected until they can survive independently. As the saying goes, "the seedlings are strong and half the harvest", seedling raising is a labor-intensive, time-consuming, and highly technical work. For the process of seedling production, the soil, wood chips and fertilizer are generally mixed together, and then the mixture is placed on the seedling tray. Then manually put the seeds one by one in each groove of the seedling tray, and then artificially spread a layer of vermiculite particles on the seedlin...

Problems solved by technology

As the saying goes, "the seedlings are strong and half harvested". Seedling raising is a labor-intensive, time-consuming and highly technical work. For the production process of seedling raising, soil, sawdust and fertilizer are generally mixed together first, and then the mixture is placed in the seedling raising tray. Then manually put the seeds one by one in each groove of the seedling tray, and then manually spread a layer of vermiculite particles on the seedling tray, which has low production efficiency and takes up a lot of manpower and material resources.

[0003] In order to solve the above problems, the patent number is CN201410219621.9, which discloses a seed precision sowing machine with synchronous transmission and sowing transmission. The sowing part, each part is connected by the conveying mechanism, and the seedling tray is placed on the conveying mechanism, and the described hole-pressing part includes the hole-pressing shaft installed on the frame, the hole-pressing wheel is installed on the hole-pressing shaft, and the hole-pressing wheel on the hole-pressing wheel The bump is in contact with the seedling tray, the seed clearing part i
