Description

Technical Field

[0001] The utility model belongs to the technical field of crop cultivation equipment, and more specifically, particularly relates to a planting rack for agricultural seeds. Background Art

[0002] Seeds are reproductive bodies unique to gymnosperms and angiosperms. They are formed by ovules through pollination and fertilization. Seeds are generally composed of three parts: seed coat, embryo and endosperm. Some plants' mature seeds only have two parts: seed coat and embryo. Before planting crops, seeds usually need to be cultivated separately and transplanted after they are cultivated into seedlings. The process of cultivating seeds into seedlings requires the use of planting racks for planting.

[0003] The existing publication number CN211745629U discloses a seed cultivation and planting rack. Although the seeds of the same batch are placed in a cultivation box, water is then injected into a water pipe and sprayed onto the seeds through a sprinkler head, and then switches are turned on separately according to the illumination time required for each cultivation box, so that the growth lamps illuminate the seeds, thereby controlling the illumination time received by different groups of seeds.

[0004] Based on the above, the inventors have discovered the following problems: However, when watering, the seed planting rack injects water into the water pipe and sprays it onto the seeds through the sprinkler head. The amount of water sprayed in each cultivation box and inside is uneven, and it is easy for some cultivation boxes to have too much or too little water inside. In addition, the planting rack does not have the effect of adjusting the spacing between each cultivation box. Different seedlings have different elongation lengths, resulting in different spacing between different cultivation boxes.

[0005] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a planting rack for agricultural seeds is provided, in order to achieve a more practical purpose. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a planting rack for agricultural seeds to solve the problem that the amount of water sprayed in each cultivation box and inside is uneven, and some cultivation boxes are prone to have too much or too little water inside.

[0007] The utility model provides a planting rack for agricultural seeds, which is achieved by the following specific technical means:

[0008] A planting rack for agricultural seeds, comprising a connecting top, support rods are fixed to the four corners of the bottom of the connecting top, a water tank is fixed to one side of the support rod, a water pump is fixed to the bottom of the inner wall of the water tank, a first drain pipe is fixed to the top of the water pump, a servo motor is fixed to the top of the inner wall of the connecting top, a reciprocating screw is fixed to the power output end of the servo motor, a screw sleeve is threadedly connected to the outer wall of the reciprocating screw, a water spray box is fixed to the outer wall of the screw sleeve, a second drain pipe is fixed to the top of the water spray box, a limit rod is fixed to the bottom of the servo motor, and a pipe retractor is provided at the top of the inner wall of the connecting top.

[0009] Furthermore, the water spray box is slidably connected to the screw sleeve, and a water spray hole is opened on the outer wall of the water spray box. There are multiple water spray holes, and the multiple water spray holes are arranged equidistantly around the circumference.

[0010] Furthermore, the first drain pipe is sealedly connected to the second drain pipe, and both the first drain pipe and the second drain pipe are connected to a pipe reel, and the sum of the lengths of the first drain pipe and the pipe reel is greater than the height of the support rod.

[0011] Furthermore, a through hole is opened through the middle of the cultivation tray, the reciprocating screw rod is located in the middle of the through hole, and the diameter of the through hole is greater than the diameter of the water spray box.

[0012] Furthermore, the horizontal cross-section of the support rod is L-shaped, and a support block is fixed to the inner side wall of the support rod. There are multiple support blocks, and the multiple support blocks are vertically equidistantly arranged.

[0013] Furthermore, the horizontal height value of the bottom end of the limiting rod is smaller than the horizontal height value of the bottom end of the reciprocating screw rod, and the bottom end of the reciprocating screw rod and the bottommost support block are at the same horizontal height value.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, a servo motor is used to drive the reciprocating screw to rotate, and the screw sleeve and the water spray box are limited by the limit rod, so that the screw sleeve and the water spray box will not rotate together, thereby allowing the screw sleeve and the water spray box to reciprocate up and down, and the spacing between two adjacent cultivation trays is the same, so that the time the water spray box stays at the bottom of any cultivation tray is also the same, and the amount of water sprayed is also the same, thereby achieving the effect of the same amount of water sprayed inside each cultivation box.

[0016] 2. In the utility model, the cultivation tray is supported by support blocks, and the spacing between the support blocks is small. The cultivation trays are placed at a certain interval of several support blocks according to the height of the seedlings after growth, thereby achieving the effect of quickly adjusting the spacing between the cultivation trays according to the height of the seed seedlings.

[0030] Among them, the first drain pipe 6 is sealedly connected to the second drain pipe 8, and the first drain pipe 6 and the second drain pipe 8 are both connected to the pipe reel 7. The sum of the length values ​​of the first drain pipe 6 and the pipe reel 7 is greater than the height value of the support rod 2. The pipe reel 7 is set to reel the excess first drain pipe 6 and second drain pipe 8 inside the pipe reel 7 to avoid the second drain pipe 8 affecting its movement when the water spray box 15 moves.
