AI Technical Summary

Technical Problem

In existing tobacco cultivation, problems such as missed planting, seedling burning, and seedling damage are prone to occur during manual transplanting of tobacco seedlings. Furthermore, existing equipment cannot effectively solve the problem of base fertilizer application, resulting in slow seedling growth and an inability to meet the needs of large-scale transplanting.

Method used

Design a tobacco seedling transplanting device including an inner cylinder and an outer cylinder. The inner cylinder is used to place tobacco seedlings, and the bottom of the outer cylinder has a cone-shaped body. The opening and closing of the cone-shaped body is controlled by a linkage mechanism. A stepped surface is set between the inner and outer cylinders to accommodate base fertilizer and avoid direct contact between the base fertilizer and the tobacco seedlings. Combined with a positioning component, the device realizes the integrated operation of opening holes, laying base fertilizer, and filling holes.

Benefits of technology

It has achieved a highly efficient transplanting process without burning or damaging seedlings, improving the efficiency of field work in tobacco planting, reducing labor costs, and meeting the needs of large-scale transplanting.

Abstract

The tobacco seedling transplanting device comprises an inner cylinder and an outer cylinder, the inner cylinder and the outer cylinder are coaxially arranged, the inner cylinder is used for throwing tobacco seedlings to be transplanted, a conical body is arranged at the bottom of the outer cylinder, the conical body is composed of a plurality of petals, each petal of the conical body is connected with the inner cylinder through a connecting rod mechanism, and the connecting rod mechanism is arranged on the conical body. When the inner cylinder moves in the axial direction relative to the outer cylinder, the conical body can be controlled to be opened and closed; a through hole and a step surface are arranged in the cone-shaped body, the size of the through hole is matched with the outer diameter of the inner cylinder, the height of the step surface is larger than that of the bottom of the cone-shaped body, and an interlayer formed by the step surface, the inner wall of the cone-shaped body and the outer wall of the inner cylinder is used for containing base fertilizer. The hole digging, base fertilizer laying and hole filling operations can be directly completed through the device, the phenomena of seedling burning, tobacco seedling damage and the like cannot be caused based on the arrangement of the conical body, the whole structure is simple, operation is convenient and fast, the field working efficiency of tobacco planting is effectively improved, and the labor cost is reduced.
