Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and equipment facilities, and particularly relates to a self-propelled tomato harvester. Background Art

[0002] The self-propelled tomato harvester is an agricultural machine used for high-efficiency harvesting of tomatoes under large-scale planting conditions.

[0003] Realizing large-scale and comprehensive mechanical harvesting of tomatoes will not only help significantly reduce the planting costs of the tomato industry, but it is also a key link in achieving balanced, controllable and high-quality supply of tomato processing raw materials, and is a key factor in the sustainable survival and development of the tomato industry. For example, since the 1950s and 1960s, the United States has begun to experiment with mechanical harvesting of tomatoes and was the first to put tomato harvesters into commercial use. After continuous development, the United States has achieved industrial upgrading in the research and development and promotion of new tomato varieties, field management technology, mechanical harvesting, sales and processing technology. In particular, the full mechanization of tomato harvesting has not only promoted the rapid expansion of the planting scale in the United States, but also promoted the rapid reduction of tomato planting costs. The harvesting costs have been reduced from 50% of production costs to 16%, which has greatly promoted the global competitiveness of the US tomato industry.

[0004] At present, tomato harvesters can be divided into two categories: self-propelled and towed. China currently imports more self-propelled tomato harvesters, such as Italian Grace and Italian MTS.

[0005] Take the Italian GUARESI self-propelled tomato harvester as an example. The machine includes hydraulic travel, hydraulic suspension, a lifting header, a vibrating separator, an electronic color sorter, a seedling separation blower, and a fruit material conveyor. It is safe, comfortable, quiet, and has high harvesting efficiency, making it an undisputed benchmark in the tomato harvester market. However, it is extremely expensive, bulky, and has a delivery cycle of more than a year. This makes it difficult to meet the differentiated size and weight requirements of various complex terrains and different planting environments, and it is also difficult to meet the diverse needs of tomato farmers in different regions for different functions and different price points.
