Strawberry picking vehicle

Abstract

The invention discloses a strawberry picking vehicle which includes a vehicle frame. Wheels are arranged below the vehicle frame to form a walking cart. The strawberry picking vehicle is characterizedin that a sliding seat is arranged on one side of the vehicle frame, and a sliding seat up-and-down moving control mechanism for controlling the sliding seat to move up and down is arranged between the sliding seat and the vehicle frame. A connecting plate is disposed on the outer side of the sliding seat, a connecting plate translation control mechanism for controlling the translation of a connecting plate is disposed between the sliding seat and the connecting plate, the connecting plate is connected with a cutoff clamping device, and the cutoff clamping device is used for cutting off and clamping strawberry pedicle. The walking cart is also provided with a camera shooting positioning system, and the positioning information output end of the camera shooting positioning system is connected with the sliding seat up-and-down moving control mechanism, the connecting plate translation control mechanism and the cutoff clamping device. The strawberry picking vehicle has the advantages thatthe strawberry picking vehicle is simple in structure and high in picking efficiency, can better adapt to various operating environments, and can better facilitate use by operators during operation.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery; in particular, it relates to a strawberry picking vehicle. Background technique [0002] In recent years, my country's strawberry cultivation area has expanded rapidly, from Heilongjiang in the north to Guangdong in the south, Shandong in the east, and Xinjiang in the west. It can be seen that strawberry cultivation occupies an important position in my country's agriculture. According to the 2014 annual data of the National Bureau of Statistics, the national strawberry production reached 3.113 million tons that year. Strawberry is a very fragile fruit and has high requirements for picking. Strawberries must be picked in time after they are ripe, especially during the full fruit period (about 30 days). The daily ripening capacity of strawberries can reach 150-200 kg per mu, and 2 laborers need to work It takes about 10 h·d-1 to finish picking. Strawberry orchards are mostly operat...

Problems solved by technology

[0003] Automated strawberry picking technology has been perfected in many developed countries in Europe and the United States, but this technology is still immature in my country

There are two types of commercialized strawberry picking robots in foreign countries. One is picking robots based on elevated strawberry planting methods. Strawberry harvesting machines, such as Spain's AGROBOT, are highly efficient, but the price of 100,000 US dollars and high requirements for the working environment make it not widely used in China

However, China's strawberry planting industry has its particularity: the strawberry field ridges do not have relatively fixed specifications, and the shapes of the ridges differ greatly from each other, which greatly increases the difficulty of strawberry picking.

However, domestic research on automated strawberry picking is limited to the laboratory stage, and there is still a long way to go from the market

[0004] At the same time, the picking execution part of the existing strawberry picking machine generally can only perform vertical, front and rear and horizontal rotation movements; the vertical, front and rear and horizontal rotation movements are realized step by step through multiple sets of transmission mechanisms, and the three movements are not carried out. Linkage, resulting in the problem of inaccuracy when performing strawberry picking actions; at the same time, the picking coverage of the existing strawberry picking machines is not large enough, and it is prone to picking dead angles
