Description

Technical Field

[0001] The present invention relates to the technical field of seeders, and particularly to the field of ginger seeders, specifically an electric self-propelled precise ginger seeder. Background Art

[0002] Big ginger is a perennial herbaceous plant of the ginger family that grows in a humid and mild environment. It has high nutritional value and health care effects and is widely used as a raw material for many spices and medicinal materials. At the same time, big ginger is also an important cash crop and food. Its fleshy rhizome has a spicy taste and rich aroma. It originated in Asia and is now widely cultivated in tropical, subtropical and temperate regions. Although big ginger is planted in various countries around the world, the main production areas are concentrated in Asia and Africa. China is the country with the largest planting area, output and export volume of big ginger in the world.

[0003] In China, the planting history of big ginger has exceeded two thousand years. Due to its value of both food and medicine, the planting area has reached 293,000 hectares, and the annual output exceeds 8 million tons, accounting for about half and two-thirds of the total world area and total output respectively. In some areas, the production and processing of big ginger have formed a unique industrial chain and become an important source of income for local residents. Shandong Province is the main planting area of big ginger, with an annual planting area of about 100,000 hectares, accounting for one-third of the national planting area. The main varieties include Shandong baby ginger, Laiwu big ginger and Laiwu small ginger, etc.

[0004] In recent years, with the increasing support from the state for the big ginger industry, the market demand has been continuously rising. However, at present, the sowing of big ginger in China is still mainly manual, which has led to problems such as low efficiency, high cost and high labor intensity. To achieve high yields of big ginger, it is essential to improve the level of mechanized sowing. However, due to the irregular shape of ginger seeds and their susceptibility to damage, the development of related sowing machinery has been slow. In addition, with the acceleration of the urbanization process, many young labor forces have flowed into cities, and the labor shortage in rural areas has also inhibited the development of the big ginger industry to a certain extent.

[0005] Precision agriculture has become a development trend. Therefore, designing a seeder that can meet the ginger planting needs in China is of great significance for promoting farmers' income increase and accelerating agricultural modernization. Although there are already some ginger seeders on the domestic market that can solve the problem of mechanized seeding, most of the equipment still operates in a semi-automatic mode, that is, a working method combining manual seed picking and mechanical sowing. This makes their structure usually more complex, and the production and maintenance costs are relatively high. In addition, these seeders still rely on manual labor for seed picking, resulting in high labor intensity and prone to problems such as seed damage and missed seeding. The versatility of ginger seeding machinery is insufficient and it is difficult to meet the personalized needs in agricultural production. During the seeding process, monitoring and operation mainly rely on manual labor, lacking mature and efficient automatic devices. This not only increases the labor intensity but also reduces the efficiency, significantly raising the production cost and making it difficult to effectively improve the automation level.
