Tread type flattening device

Abstract

The invention relates to a tread type flattening device, which comprises a main shaft, wherein traveling devices respectively sleeve the two sides of the main shaft, the two ends of the main shaft are respectively and fixedly connected with a driving device, the middle part of the main shaft is fixedly connected with a pull plate, the other end of the pull plate is connected with a flattening block, the middle part of the main shaft is further fixedly connected with a handrail frame, and the other end of the handrail frame is fixedly connected with a handrail. The tread type flattening device has the advantages that by adopting a tread type driving mechanism, a manual method is replaced to pull the flattening block to flatten a paddy field, the labor intensity is decreased, the workload of people working in the paddy field is reduced, and the long-time soaking in the paddy field is avoided; the setting of transmission ratio of each driving gear and the corresponding driven gear is proper, the setting of the diameter relationship of each driven gear and a corresponding traveling wheel is reasonable, the torque required by the rotation of each driven gear is reduced, and a user can conveniently push the traveling wheels to move forwards; a gap is reserved between each driven gear and the corresponding traveling wheel, so the interference between each traveling wheel and a crank is avoided; the land flattening block is positioned behind the main shaft, so the counterweight function on the main shaft is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural labor tools, in particular to a foot-operated leveling device. Background technique [0002] There are a large number of terraced fields distributed in the southeastern hilly areas of my country. Terraces are generally cultivated on hills with a slope of less than 30° to meet the needs of small arable areas in some areas of my country. Due to the special terrain, modern agricultural machinery is difficult to use in terraced fields. [0003] Paddy fields generally need to be beaten and leveled. With the popularization of modern agricultural machinery, paddy fields can be leveled by leveling machines. The two ends of the wood used to level the paddy field are tied with ropes, and the laborers pull the rope to move the wood forward, so as to achieve the purpose of leveling the paddy field. In addition, in order to ensure that the wood does not deviate, a person behind the wood usually needs to c...

[0002] There are a large number of terraced fields distributed in the hilly areas of southeastern my country. Terraced fields are generally reclaimed on hills with a slope of less than 30° to meet the needs of small arable areas in some areas of my country. Due to the special terrain, modern agricultural machinery is difficult to use in terraced fields.

[0003] Paddy fields generally need to be beaten and leveled. With the popularization of modern agricultural machinery, paddy fields can be leveled by leveling machines. The two ends of the wood used to level the paddy field are tied with ropes, and the laborers pull the rope to move the wood forward, so as to achieve the purpose of leveling the paddy field. In addition, in order to ensure that the wood does not deviate, a person behind the wood usually needs to correct the wood in time. And assist the former to push the wood. This kind of flat ground method is relatively primitive, with low work efficiency and high labor intensity, and the working conditions in the paddy field are harsh.
