Description

Technical Field

[0001] This utility model relates to the field of rice transplanting technology, and in particular to a stepless speed regulation device for the transplanting frequency of a high-speed rice transplanter. Background Technology

[0002] High-speed rice transplanters, as key equipment for improving rice planting efficiency and quality in modern agricultural production, have been widely used in recent years. With the acceleration of agricultural modernization, farmers have placed higher demands on the operational performance and adaptability of high-speed rice transplanters. Transplanting frequency is one of the important parameters affecting the operational effect of high-speed rice transplanters. A suitable transplanting frequency ensures that seedlings are rationally distributed in the field, which is beneficial to seedling growth and increases crop yield. Different paddy field environments (such as soil texture, field size and shape), rice varieties, and agronomic requirements all necessitate precise adjustment of the transplanting frequency to achieve the best transplanting results.

[0003] In existing devices, the length of the transplanting arm is mostly fixed. When facing different transplanting distances, different transplanting arms need to be replaced, making it difficult to meet the different transplanting requirements of different seedlings. Therefore, a stepless speed regulation device for transplanting frequency of high-speed rice transplanter is proposed. Utility Model Content

[0026] The positioning frame 3 is fixedly connected to the outside of the slider 202. The inside of the fixed frame 1 is provided with a slide rail, which enables the slider 202 to slide.

[0027] One end of the connecting rod 5 is fixedly connected to the mounting plate 7, and one end of the mounting plate 7 is fixedly connected to the reinforcing rod 8. The mounting plate 7 serves to fix the reinforcing rod 8.

[0028] One end of the reinforcing rod 8 is fixedly connected to a connecting rod 9, and one end of the connecting rod 9 is fixedly connected to a U-shaped stop 10. The U-shaped stop 10 ensures that the seedlings can be successfully inserted into the paddy field.

[0029] The mounting plate 7 has internal threaded connections with bolts 11, and the top surface of the mounting plate 7 is provided with a rice planting plate 12. The rice planting plate 12 is used to insert the rice seedlings into the soil.

A rotating rod 6 is fixedly connected to one side of the gearbox 14. The gearbox 14 is used to adjust the rotation frequency of the device.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When using, start the hydraulic rod 201. The hydraulic rod 201 drives the slider 202 to move. The movement of the slider 202 causes the transplanting plate 12 to move. The position of the transplanting plate 12 in the fixed frame 1 can be adjusted.
