A castor harvester

Abstract

The invention provides a castor harvester which comprises a vehicle body and a cab. The castor harvester further comprises a harvesting box, a hydraulic lifting device and a conveying and screening device. The harvesting box is arranged in the front of the vehicle body. The hydraulic lifting system is arranged behind the harvesting box. The cab is arranged in the middle of the vehicle body. The conveying and screening device is arranged below the vehicle body and is tightly close to the harvesting box. According to the castor harvester, the structure is reasonable, equipment space is saved, the manufacturing cost is reduced and energy consumption is low. The height from the harvesting mechanism to the ground and the angle of harvesting rods can be adjusted, and omitted harvesting of castor fruits at low positions is avoided; meanwhile, high plants can smoothly enter the harvesting box under the effect of a plant guide plate, and the problem that fruits are lost when castor plants collide with the harvesting mechanism or even are broken is avoided; it can be ensured that fruits are effectively separated from castor leaves by the adoption of the multi-level screening mechanism, and the fruit thorough-picking rate is improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a castor harvester. Background technique [0002] Castor bean is a common annual herb. Castor bean has high medicinal value such as detumescence and detoxification, dredging collaterals and orifices. At the same time, castor oil also has high economic value such as dyeing aid, lubrication and plasticization. Therefore castor-oil has been planted on a large scale as a kind of economic crop with small investment, quick effect and high benefit. Due to the dense castor fruit, hard fruit and thorny surface, it is very difficult to manually harvest castor. At the same time, manual harvesting requires two parts of harvesting, the fruit and the castor seedling. The efficiency is low and the input cost is high, which can no longer meet the requirements of the existing castor planting. demand. The traditional castor harvesting mechanism is to harvest the castor plant as a whole into...

Problems solved by technology

Due to the dense castor fruit, hard fruit and thorny surface, it is very difficult to manually harvest castor. At the same time, manual harvesting requires two parts of harvesting, the fruit and the castor seedling. The efficiency is low and the input cost is high, which can no longer meet the requirements of the existing castor planting. needs

The traditional castor harvesting mechanism is to harvest the castor plant as a whole into the harvesting box, in the harvesting box, the castor seedling and the castor fruit are separated through structures such as comb teeth, and the castor seedling is further spit out. This harvesting method The disadvantage is that the castor fruit on the castor seedlings has a low detachment efficiency, and some castor fruits will be entrained in the process of spit out the castor seedlings, resulting in entrainment loss. Generally speaking, the traditional castor harvesting mechanism has a low yield At the same time, there is no seedling guide plate above the traditional castor harvesting mechanism. When the castor plant is too high, it will cause difficulty for the castor plant to enter the harvesting mechanism, which will lead to a large loss of castor fruit
