Description

Technical Field

[0001] This utility model relates to the technical field of fruit and vegetable breeding equipment, specifically a coconut coir substrate addition device for fruit and vegetable breeding boxes. Background Technology

[0002] In the field of fruit and vegetable breeding, the substrate environment inside the breeding box directly affects the quality of seedling cultivation. Coconut coir, with its water retention, air permeability, and balanced nutrition, has become a high-quality substrate widely used in breeding boxes.

[0003] Currently, the addition of coconut coir still relies on traditional methods: workers carry a bucket full of coconut coir in one hand and scoop it into the seedling box with a spoon in the other. This operating mode has obvious shortcomings: on the one hand, coconut coir is easily spilled during scooping and pouring, which not only wastes materials but also increases the workload of subsequent cleanup; on the other hand, it is difficult to accurately control the amount when adding it manually with a spoon, often resulting in uneven thickness of coconut coir in the seedling box, affecting the consistency of the seedling growth environment, thereby reducing the overall addition efficiency and causing inconvenience to large-scale, high-standard fruit and vegetable breeding work.

A control box 8 and a motor 9 are fixedly installed at the upper end of the top cover 7. A support frame 12 is fixedly installed inside the material cylinder 1, and a vertical tube 13 is rotatably installed in the middle part of the support frame 12. A conveying screw 15 is coiled on the vertical tube 13 and inserted into the discharge pipe 4. A docking groove 14 is provided at the top of the vertical tube 13. A motor shaft is provided at the output end of the motor 9 and penetrates the top cover 7. A docking rod 17 is provided at the bottom end of the motor shaft and inserted into the docking groove 14.

[0026] The middle of the connecting rod 17 is a cylindrical structure, and the two sides of the connecting rod 17 are rectangular structures.

[0027] The bottom shell 3 and the discharge pipe 4 are integrated structures, the material cylinder 1 and the vertical cylinder 2 are integrated structures, the bottom shell 3 is fastened to the bottom end of the vertical cylinder 2, and the bottom shell 3 and the vertical cylinder 2 are threadedly connected. The lower end of the top cover 7 and the upper end of the material cylinder 1 are provided with connecting plates, and the two connecting plates are fixed by screws.

[0028] The top cover 7 is provided with a feeding pipe 10 at its upper end, and a cover 11 is provided at the top of the feeding pipe 10. The cover 11 is fastened to the top of the feeding pipe 10 and is threadedly connected to the feeding pipe 10.

[0029] When using this device, first remove the cover 11 from the top of the feeding tube 10 by rotating it. Then add an appropriate amount of coconut coir substrate into the material cylinder 1 through the feeding tube 10. After adding, fasten the cover 11 to the top of the feeding tube 10 and tighten it.

[0030] During assembly, the bottom shell 3 and the discharge pipe 4 are integrated structures, and the material cylinder 1 and the vertical cylinder 2 are integrated structures. The bottom shell 3 is fastened to the bottom end of the vertical cylinder 2 and fixed by threaded connection. The lower end of the top cover 7 and the upper end of the material cylinder 1 are provided with mating plates. The two mating plates are fixed by screws, thereby completing the installation of the top cover 7 and the material cylinder 1.

[0031] The control switch 6 is a push-button switch.

[0032] The staff member holds the handle 5 on one side of the vertical cylinder 2, inserts the discharge pipe 4 into the designated fruit and vegetable breeding box, presses the control switch 6 on the handle 5 (the control switch 6 is a push-button switch), and the independent power supply in the control box 8 supplies power to the motor 9 and other electrical equipment, and the control module starts the motor 9.

[0033] The edge of the conveying screw 15 is attached to the inner wall of the discharge pipe 4.

[0034] A sealed bearing is inlaid in the middle part of the support frame 12. The inner ring of the sealed bearing is penetrated by the vertical tube 13 and is interference-fitted with the vertical tube 13.

[0035] Two support rods are symmetrically arranged on the outer wall of the vertical tube 13, and the outer end of the support rod is provided with a scraper rod 16 that contacts the inner wall of the material cylinder 1.

[0036] After the motor 9 starts, the connecting rod 17 will rotate the vertical tube 13 inside the material cylinder 1. When the vertical tube 13 rotates, the scraping rods 16 at the outer ends of the two symmetrically arranged support rods on its outer wall will rotate on the inner wall of the material cylinder 1. At the same time, the conveying screw ribbon 15 (whose edge is attached to the inner wall of the discharge pipe 4) coiled on the vertical tube 13 will also rotate. The conveying screw ribbon 15 is inserted into the discharge pipe 4. During the rotation, the coconut coir substrate in the material cylinder 1 can be discharged at a uniform speed at the discharge pipe 4.

[0037] The support frame 12 fixed inside the material cylinder 1 has a sealed bearing embedded in the middle part. The inner ring of the sealed bearing is penetrated by the vertical tube 13 and is interference-fitted with the vertical tube 13, which provides stable support for the rotation of the vertical tube 13.
