Background technique

As one of the main economic crops, carrots are widely distributed in the world. my country is the country with the largest carrot harvesting area in the world, and its total output accounts for 1/3 of the world's total carrot output. Compared with other crops, the mechanization level of carrots in my country is very low at present, and the harvesting methods are mainly manual harvesting and semi-mechanized segmental harvesting. In mechanical harvesting, the excavation plow is mainly used to excavate carrots for single-function segmental harvesting or use The potato harvester performs combined harvesting, and a lot of follow-up work needs to be done manually. Therefore, it is an important task for agricultural machinery researchers in my country to design a combined harvesting machine specially used for carrots to realize multiple functions such as excavation, transportation, soil removal, root and leaf separation, and collection of carrots.

For ordinary carrot harvesters, the carrots are only scooped up from the soil by digging a shovel, and then placed behind the machine. This method not only easily damages the carrots buried in the soil, but also easily digs out During the process of laying the carrots behind the machine, the carrots were buried again by the soil, and it was more difficult to manually pick up the carrots, and it was easy to miss those buried carrots; the carrot harvester we designed was designed with a seedling support mechanism, clamping Mechanism and seedling separation mechanism, which uses the method of clamping and lifting carrot seedlings to pull carrots out of the soil. After passing through the soil removal mechanism, the carrots with seedlings are transported to the top-cutting mechanism to separate carrots from seedlings. The harvested seedlings and carrots are output separately through the seedling-fruit separation mechanism, which can avoid the missed inspection of carrots, and the harvested carrots are clean, which can directly meet the bagging requirements.

Chain baffles are fixedly connected at equal intervals on the lifting conveyor belt, which can effectively prevent the carrots from falling back during the lifting process, and can evenly distribute the carrots on the lifting conveyor belt, avoiding damage caused by excessive concentration of carrots. The chain load is too large; the two sides of the lifting conveyor belt are fixedly connected with side conveyor chain drive chains, and the side conveyor chain drive chains are articulated on the main drive sprocket and the driven sprocket.

The seedling and fruit separation mechanism of a carrot harvester described in the utility model can effectively separate the seedlings from the carrots after the top has been cut, and has a good net effect of removing impurities, and can realize lifting and loading of carrots or loading The bag saves the process of manually picking up carrots, saves costs and has high efficiency. This mechanism can effectively improve the working efficiency of the carrot harvester.
