Description
Technical Field
The invention relates to the technical field of crop topping devices, in particular to a pneumatic cutting recovery device for tobacco topping.
Background
In the planting process of tobacco plants, the plants need to be topping so as to eliminate the dominant position at the tops of the plants and promote the growth of the lower positions in the plants.
Among the prior art, patent CN206651082U provides a plant collection machine of topping, and it includes shell, motor, cutting member and collection fill, and the delivery outlet has been seted up to shell one end, the delivery outlet with collect fill intercommunication for collect remaining cut thing, topping in-process, through the motor rotation drive cutting blade high-speed rotation, the air current from bottom to top moves, works as cutting blade cuts the plant and is cut the thing, under air current and inertial action, is cut the thing and passes through the feed inlet gets into collect fill, is cut the thing and is in under the filtration of afterbody baffle, preserve in the collection fill, the air passes through the exhaust hole of baffle is discharged. In this scheme, the length that needs excision at plant top is shorter, and plant top gets into in the casing from shell downside opening to by the topping. Therefore, the scheme is suitable for topping crops with short top distance to be topping, and for tobacco plants, the required top distance to be topping is long (generally 20cm-30 cm), and the topping by using the topping mechanism has the problems that the top of the plant is too long to enter a shell, the top of the plant is too long to be cut off in time, and the plant is easy to be entangled with a cutter and cannot be discharged. In addition, patent CN115380727a discloses a technical solution in which plant leaves are pressed down by a deflector so as to expose terminal buds.
Disclosure of Invention
The invention aims to: in order to overcome the defects in the prior art, the invention provides a pneumatic cutting recovery device for tobacco topping, which is suitable for the topping requirement of tobacco crops.
