Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a power transmission device for a tobacco-grain intercropping and rotary tillage system. Background Technology

[0002] With the intensifying greenhouse effect, the "high-temperature stress" caused by global warming poses a new and serious threat to global food security. The scarcity of land resources in tobacco-growing areas has led to an increasingly serious problem of continuous cropping of flue-cured tobacco. To address the obstacles of continuous cropping and low overall efficiency in flue-cured tobacco cultivation, upgrading and transforming existing large-scale tobacco planting methods is crucial. Research on a strip-planting model that integrates major grain crops with tobacco and combines agricultural machinery and agronomy is of great significance for achieving coordinated development of tobacco and grain, and for reducing labor and increasing income for tobacco farmers.

[0003] In the tobacco-wheat intercropping model, where tobacco is intercropped with wheat, sweet potatoes, and peanuts, the stubble needs to be cleared after wheat harvest. Existing rotary tillage machinery cannot effectively remove the stubble. When cultivating and hilling tobacco seedlings transplanted to flat land, existing machinery has a narrow tillage width, shallow tillage depth, and insufficient hilling volume, failing to meet the technical standards for tobacco production. Therefore, there is an urgent need to develop a cultivation machine suitable for tobacco strip intercropping models, with the power transmission device being a key component. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a power transmission device for a tobacco-grain intercropping and rotary tillage system.

[0005] The technical solution of this utility model is implemented in the following manner:

[0006] The power transmission device for a tobacco-grain intercropping rotary tillage and hilling system includes a frame with a gearbox fixedly connected to the middle. The gearbox includes a gearbox housing, a front bearing seat connected to a front bearing seat cover on the front side of the housing, and an input shaft rotatably connected to the front bearing seat via an input shaft bearing. The input shaft has a splined portion on its outer end and a bevel gear on its inner end. A left bearing seat connected to a left bearing seat cover is located on the left side of the gearbox housing, and a first output shaft is rotatably connected to the left bearing seat cover. A right bearing seat connected to a right bearing seat cover is located on the right side of the gearbox housing, and a second output shaft is rotatably connected to the right bearing seat cover. The first and second output shafts are integrated into one unit. The gearbox has a through shaft, and the second output shaft inside the gearbox is connected to an output shaft bevel gear, which meshes with the input shaft bevel gear. A spacer sleeve is fitted on the second output shaft between the output shaft bevel gear and the right bearing. The upper end face of the gearbox is connected to the gearbox cover. The input shaft of the gearbox is connected to the tractor's power output shaft via a universal joint. The frame is equipped with a first support base and a second support base. The first support base is rotatably connected to the first output shaft. The second support base is rotatably connected to the second output shaft. A first sprocket is fixed to the end of the first output shaft, and a second sprocket is fixed to the end of the second output shaft. The first sprocket is connected to the first rotary tiller sprocket via a first chain, and the second sprocket is connected to the second rotary tiller sprocket via a second chain.

[0007] Preferably, the gearbox cover is provided with an air vent bolt.

[0008] This utility model has the following advantages:

[0009] The power transmission device of this tobacco-grain intercropping rotary tillage and hilling device uses an input shaft to drive an input shaft bevel gear, which in turn drives an output shaft bevel gear. The output shaft bevel gear drives the first and second output shafts respectively. The first output shaft drives the first sprocket, which in turn drives the first rotary tillage sprocket via a first chain. The first rotary tillage sprocket then drives the first rotary tillage shaft. The second output shaft drives the second sprocket, which in turn drives the second rotary tillage sprocket via a second chain. The second rotary tillage sprocket then drives the second rotary tillage shaft. This structural design splits the power transmission on both sides, enabling the tobacco-grain intercropping rotary tillage and hilling device to be used for rotary tillage and hilling operations on the tobacco seedlings.
