Helical cleaning type planting belt cleaning device

Abstract

The invention provides a helical cleaning type planting belt cleaning device, which comprises a frame, a helical screw, at least two stubble removal spades, a straw guide and a lateral baffle. The helical cleaning type planting belt cleaning device is characterized in that thread pitch of a helical vane on the helical screw gradually increases along the moving direction of materials, the lateral baffle perpendicular to an axis of the helical screw is mounted on the frame and close to a small thread pitch end of the helical vane, the stubble removal spades are fixed on the frame, the rear end of each stubble removal spade 8-10cm higher than the outer periphery of the helical screw passes by the bottom of the helical screw and extends to the front end horizontally by being close to the land, the front end of each stubble removal spade is an edged slope, the straw guide axially along the helical screw is as wide as the interior of the frame, the straw guide the same as the stubble spades in radian is mounted on the inner side of every stubble removal spade, the front end of the straw guide is level to the outer periphery of the helical screw in the perpendicular direction, the rear end of the straw guide is level to the rear end of each stubble removal spade, and a gap between the straw guide and the outer periphery of the helical screw is 2-3cm. The helical cleaning type planting belt cleaning device can be used for removing stubbles in front of a ditcher and removing straws at the front end of the ditcher, and is excellent in operating performance.

Description

technical field [0001] The invention relates to a spiral cleaning type seed belt cleaning device, which belongs to the technical field of agricultural machinery. Background technique [0002] As a modern agricultural production technology to increase corn yield, increase soil organic matter, and prevent excessive evaporation of surface water, corn no-tillage sowing has gradually been accepted by more and more regions, and seed belt cleaning and anti-congestion technology are the core links of this technology However, it has been difficult to be completely broken through, which seriously limits the popularization and application of this technology. For example, most patents adopt the form of crushing and returning to the field to create a good ditching and sowing environment for the operation of the seeder. For example, 02114625.X uses a roller hammer claw device to complete the crushing of straw. Although this structure can complete the crushing of straw, it consumes a lot o...

Problems solved by technology

[0002] Corn no-tillage sowing, as a modern agricultural production technology to increase corn yield, increase soil organic matter, and prevent excessive evaporation of surface water, has gradually been accepted by more and more regions, and seed belt cleaning and anti-congestion technology are the core links of this technology However, it has been difficult to be completely broken through, which seriously limits the popularization and application of this technology.

For example, most patents adopt the form of crushing and returning to the field to create a good ditching and sowing environment for the operation of the seeder. For example, 02114625. , the vibration is severe, and it will lead to the deterioration of the working environment; there are also seed belt cleaning devices that remove the straw, such as 200910073177.3, which uses a rotating spring tooth type seed belt cleaning device. The straw in the front is moved to the back of the ditch opener. Although this kind of belt cleaning device does not need to crush the straw, but because the spring teeth are 2cm away from the ground surface, it can only clean part of the short straw. Complicated working conditions cannot guarantee the quality of work, so its application is greatly limited

There is also a vertical shaft type seed tape cleaning device, although the structure is simple, but it can only be adapted to the seed tape cleaning when the straw coverage is small and the straw humidity is low, and it is difficult to meet the seed tape cleaning in different regions, different straw lengths and humidity
