Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of planting, in particular to a nutrient uniform mixing device for vegetable planting in facilities. Background Art
[0002] In the process of vegetable cultivation in facilities, uniform mixing of nutrients is crucial to the growth of vegetables. In traditional vegetable cultivation, nutrients are often mixed by manual stirring or simple mechanical stirring. However, these methods have many disadvantages. Manual stirring is difficult to ensure the uniformity of nutrient mixing, and it is easy for local nutrient concentrations to be too high or too low, which will cause uneven growth of vegetables. Moreover, simple mechanical stirring may have dead corners and cannot achieve the ideal uniform mixing effect. This not only affects the yield of vegetables, but may also reduce the quality of vegetables. To solve these problems, there is an urgent need for a device that can achieve uniform mixing of nutrients in vegetable cultivation in facilities.
[0003] During the planting process, fertilization needs to be carried out continuously. The nutrients needed for the production period need to be mixed and then fertilized using fertilization equipment. Most nutrients are solid particles or powder fertilizers, which are prone to agglomeration or large particles. In addition, during the stirring process, the nutrients will accumulate at the bottom due to gravity, and there will be residual nutrients in the cylinder wall that are not completely mixed.
[0004] The existing patent (publication number: CN217527297U) discloses a nutrient mixing device for fruit tree planting, which relates to the technical field of fruit tree planting. The nutrient mixing device for fruit tree planting includes a box body, a crushing component and a stirring component. Handles are fixedly installed on both sides of the box body, and a partition is fixedly installed on the inner wall of the box body. Filter buckets are fixedly installed on both sides of the partition, and one side of the filter bucket is fixedly installed on the inner wall of one side of the box body. The crushing component is arranged on the box body, and the stirring component is arranged on the box body. This utility model can crush nutrients with larger particles through the coordinated use of a motor, a rotating rod, a stirring piece, a crushing blade and a toggle plate. The setting of the auxiliary plate speeds up the feeding rate of nutrients. The coordinated use of a rotating rod, a mounting box, a bevel gear and a cam can effectively save time. The coordinated use of a connecting cross bar and a scraper plate can mix and stir nutrients to reduce adhesion. The up and down shaking of the elastic toggle plate can effectively prevent a large amount of nutrients from accumulating at the bottom.
[0005] In view of the above problems, existing patents have provided solutions. However, when mixing nutrients, due to the lack of a negative pressure reciprocating mixing and multiple screening structure, the nutrients cannot be processed by negative pressure reciprocating mixing and multiple screening, which reduces the flexibility of mixing nutrients for facility vegetable cultivation.

[0047] Working principle: First, connect the feeding valve 32 to the nutrient raw material conveying equipment, and then connect the discharge valve 2 to the nutrient storage equipment. Then, fill the medicine storage ring tube 33 with the required mixed medicine liquid, and then energize and start the servo motor 411. The servo motor 411 will drive the centrifugal inner cylinder 412 to rotate, and the centrifugal inner cylinder 412 will drive the feeding mesh plate 413, the coarse screen soft funnel 422 and the fine screen soft funnel 423 to rotate together. The coarse screen soft funnel 422 and the fine screen soft funnel 423 will make the inner side of the coarse screen soft funnel 422 and the inner side of the fine screen soft funnel 423 reciprocate up and down along the reciprocating screw rod 421 when rotating. Then, the coarse screen soft funnel 422 and the fine screen soft funnel 423 will make the centrifugal inner cylinder 412 rotate in the reciprocating motion. Negative pressure and pressure are generated inside 412. When negative pressure is generated, the torsion spring cover 35 can be opened by the negative pressure, and then the medicine liquid in the medicine storage ring tube 33 will be transported to the nutrient raw material through the medicine delivery tube 34, and then the nutrient raw material will be mixed with the medicine liquid due to the centrifugal force generated by the rotation of the centrifugal inner cylinder 412, and when the coarse screen soft funnel 422 and the fine screen soft funnel 423 are squeezed, the tank cover 31 will automatically close with its own torque due to the loss of negative pressure, and form a closed environment in the centrifugal inner cylinder 412, and then the nutrient raw material and the medicine liquid will pass through the coarse screen soft funnel 422 and the fine screen soft funnel 423 with the pressure, and finally flow into the feeding mesh plate 413, and then flow through the feeding mesh plate 413 along the mixing tank 1 to the discharge valve 2 for discharge.
