Strip seed bed stubble cleaning device

Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a belt-shaped seedbed stubble clearing device. The device is composed of a soil cutting and digging device, a soil separating device and a power transmission mechanism which are installed on a machine frame, wherein the soil cutting and digging mechanism is composed of a machine frame front beam connecting plate, an adjusting spring, a mechanism adjusting rod set, a soil cutting disc assembly, a soil cutting plate and a soil cutting plate adjusting rod set, the soil separating device is composed of a grid fixing plate, a primary soil separating mechanism and a secondary soil separating mechanism, and the power transmission mechanism is composed of a soil separating power chain wheel, a seeding power chain wheel, a middle chain wheel shaft, a transmission chain and a transmission chain wheel. When a seeding machine moves forwards, the soil layer in a belt-shaped seeding zone is cut and conveyed to the soil separating mechanism through the soil cutting and separating device, a primary soil separating wheel and a secondary soil separating wheel are driven by the chain wheels and chains to rotate, so that soil is separated from straw and stubble in a seedbed, and then a seed channel is pressed by a pressing device, so that a sound seedbed environment is created.

Description

Technical field [0001] The invention belongs to the technical field of agricultural machinery, and particularly relates to a belt-shaped seed bed stubble cleaning device. Background technique [0002] In the field of agricultural machinery technology, no-tillage planters are used for no-tillage planting operations under the conditions of no-tillage soil with straw cover on the ground and stubble on the plough layer. The seed bed is the soil environment where seeds germinate and emerge. Due to the influence of layered root stubble, the opener cannot maintain the same amount of soil disturbance in the seed furrow during furrowing operations, and the phenomenon of drying seeds will occur after the seeds are sown on the straw, which affects the contact between the seeds and the soil, or a large amount after sowing The straw covering the surface of the seed furrow affects the germination and emergence of seeds. [0003] At present, in order to solve the problem of stubble in the cultiv...

Problems solved by technology

[0002] In the field of agricultural machinery technology, the no-tillage seeder performs no-tillage sowing operations under the condition of no-tillage soil covered with straw on the surface and root stubble in the plow layer. The seed bed is the soil environment for seed germination and seedling emergence. Due to the influence of layer stubble, the opener cannot maintain a consistent amount of soil disturbance in the seed ditch when the ditch is opened, and the phenomenon of seed drying will occur after the seeds are sown on the straw, which will affect the contact between the seeds and the soil, or a large amount of soil after sowing Straw covered on the surface of the seed ditch affects the germination and emergence of seeds

[0003] At present, in order to solve the problem of stubble on the plow layer and the straw covering on the surface, so that there is no stubble in the ditch and on the surface after ditching and sowing operations, the surface straw anti-blocking and cleaning device is often used to clean the surface straw, and at the same time, the rotary The tillage device crushes the soil and stubble in the plow layer to reduce the impact of the surface layer of straw and stubble on the seedbed after operation during no-tillage operation, but this makes the straw cleaning device a large amount of disturbance to the soil and damages the seedbed. Agglomerated soil structure in the bed, which is not conducive to seed germination and crop growth

In addition, there are other devices, such as the inclined disc stubble cutting device designed by the patent No. ZL200610002075.9 "A device for cutting straw, breaking stubble and ditching", which cannot guarantee the safety of cutting stubble and cleaning straw on the seeding belt. Stability, even cause congestion of surface straw

The active driving lever anti-blocking device designed by the patent No. ZL201110126835.8 of the "active lever type anti-blocking device" and the patent No. ZL200810225477.4 of the "active reciprocating no-tillage anti-blocking unit body" is easy to cause the surface The straw is crowded on the sowing belt, and consumes a lot of power. This device can only clean the straw on the surface sowing belt, but not the residue in the plow layer.

Patent No. ZL201020160603.5 "Concave Concave Double Disc Type Seed Belt Cleaning Device" The concave disc cleaning device needs a large positive pressure to assist in soil entry, and is only suitable for surface layer with less straw coverage surface conditions

At the same time, the belt-shaped rotary tiller uses the power-driven rotary tiller to crush the soil and root stubble in the plow layer, but it disturbs the soil a lot and causes a lot of power consumption.
