Description

Technical Field

[0001] The present invention relates to the technical field of agricultural sowing machinery, and in particular to a soil improvement device for agronomic planting. Background Art

[0002] At present, after a period of crop planting, the fertility of the soil will decline. Salinization or compaction are common phenomena of fertility decline. To address this situation of fertility consumption due to planting, the traditional method is to burn the straw back into the field. However, large-scale straw burning will pollute the environment, so only some chemical improvement measures can be taken at present, such as the rational application of soil improvement fertilizers, which can effectively improve soil properties, increase soil fertility, create good soil environment conditions for crop production, and promote the healthy growth of crops.

[0003] After searching, it was found that the fertilizing mechanism in the existing technology can only throw the waste into a corner of the tunnel when applying granular waste, which cannot achieve the effect of sufficient mixing with the soil. The operation of turning over the soil and mixing is required in the later stage, which undoubtedly prolongs the working time, lengthens the process and reduces production efficiency.

[0016] 1. Through the discharge pipe set on the rear side of the soil turning cone plate, combined with the triangular dividing block inside the pipe and the oblique discharge holes facing both sides, the quantitatively falling fertilizer can be scattered into the soil that has been turned over on both sides, thus avoiding the fertilizer from all falling and gathering in a certain place, so as to achieve a mixing effect.

[0017] 2. Through the impact feeding barrel and the collection elbow bent to the top of the lower feeding pipe, when quantitative discharge is required, you only need to pull the rack top rod downwards first, and then suddenly release it. Under the action of the reset spring, the disc suddenly impacts upwards, pushing the fertilizer on the spring support net to the drooping section of the collection elbow. Then, open the solenoid valve to drain the fertilizer in the drooping section of the collection elbow into the discharge pipe.

[0018] 3. By setting up the reduction motor and scraper, when the fertilizer is about to be spread or when there is a blockage, you only need to start the reduction motor to drive the scraper at the bottom to run, and then turn over the waste at the bottom to assist in the leakage.
