Abstract

The invention discloses a flexible swing type lateral straw-cleaning anti-blocking seedbed preparation device which comprises a frame, a gearbox, a swing arm, a bearing seat, a flexible straw-cleaning part, a swing shaft and other structures. The method is characterized in that: the flexible straw cleaning component is formed by symmetrically fixedly installing elastic tooth shafts at the lower sides of elastic tooth plates and respectively fixedly installing elastic teeth on the elastic tooth shafts, so that soil is not moved, power consumption is low, operation is stable, and the obstacle avoidance function of the flexible straw cleaning component during operation can protect the device to improve operation stability.

Description

Flexible swing type lateral straw-removing anti-blocking seedbed preparation device

Technical Field

The invention relates to a novel straw-clearing and anti-blocking device, in particular to a flexible swing type straw side-clearing seedbed preparation device, and belongs to the field of agricultural machinery.

Background

The protective cultivation technique has the advantages of improving soil, storing water, preserving soil moisture, preventing wind erosion and water erosion, and the like. With the increase of the unit yield of crops, a large amount of straws remained on the ground surface of the previous crops cover the ground surface to restrict the seeding of the next crops, and the environmental pollution caused by the straw burning mode in the field is also prohibited by the strict regulations. The prior no-tillage passive straw-clearing seeding device mostly adopts the operation of increasing the dead weight of the machine body and cutting straws and ditching by a disc, and the operation mode causes serious soil compaction; the active straw-cleaning no-tillage seeding device throws out the straws longitudinally or laterally by means of high-speed rotation of the straw-cleaning component, and the operation mode has the advantages of large soil movement amount, large power consumption, serious soil moisture scattering, damage to beneficial organism groups and increased production cost, and cannot meet the requirement of modern agriculture on no-tillage seeding operation of the stubble field.

Therefore, a no-tillage seeding and straw-cleaning seedbed preparation device which can realize no-tillage soil movement, good straw-cleaning effect and stable work is urgently needed.

Disclosure of Invention

Aiming at the defects, the invention provides a flexible swing type lateral straw-clearing and anti-blocking seedbed preparation device.

In order to solve the technical problems, the invention is realized by the following technical scheme: a flexible swing type lateral straw-cleaning anti-blocking seedbed preparation device comprises: frame, gearbox, swing arm, bearing frame, flexible clear straw part, pendulum shaft, clear straw cowling panel, land wheel, cylinder cam structure constitute, its characterized in that: a gear box is fixedly arranged at the upper part of a frame, land wheels are fixedly arranged at two sides of the rear part of the frame, 4 bearing seats are fixedly arranged at the middle part of the frame transversely and longitudinally respectively and are provided with swing shafts capable of swinging through the bearing seats, flexible straw cleaning parts are symmetrically and fixedly arranged at the middle parts of the swing shafts, swing arms are fixedly arranged at the front parts of the swing shafts, cylindrical cams are fixedly arranged at two sides of the gear box, the swing arms are connected with the cylindrical cams in a sliding manner, the flexible straw cleaning parts are formed by symmetrically and fixedly arranging elastic tooth shafts at the lower sides of the elastic tooth plates and respectively fixedly arranging elastic teeth on the elastic tooth shafts, and straw cleaning rectifying plates are symmetrically and swingably arranged at two sides of the flexible straw cleaning parts through the frame, so that a.

The invention has the advantages that; a flexible swing type lateral straw-cleaning anti-blocking seedbed preparation device changes a rotary part into a swing part, soil is not moved, power consumption is low, operation is stable, the device can be protected by an obstacle avoidance function during operation of the flexible straw-cleaning part to improve operation stability, straws enter furrows through a straw-cleaning rectification plate and are compacted through land wheels, water storage and soil moisture preservation are realized, rainwater is prevented from eroding soil in runoff of the furrows, and the heat generated by fermentation of the furrows in spring in northern alpine regions can be used for improving the ground temperature to facilitate seed germination.
