Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and more specifically, to a device for sowing and covering sandy land for agricultural planting. Background Art

[0002] Sandy soil refers to soil that is a mixture of more than 80% sand and less than 20% clay. Sandy soil is suitable for growing peanuts, watermelons, sweet potatoes, cacti, aloe vera, etc. Since these crops are relatively cold-resistant, it is most appropriate to grow them in sandy soil. Alternatively, measures such as soil improvement and water-saving irrigation can be taken to produce other crops. When improving sandy soil, a sowing and covering device is required to cover the soil, turning over the soil in the lower layer of the sandy soil so that the lower layer of soil covers the original surface, thereby achieving the effect of soil improvement. However, the existing sandy land sowing and covering device has the following shortcomings when covering the sandy land: the sandy soil is turned over by the covering blades and the covering plate on the covering device, and the sandy soil is relatively loose in texture, and the covering effect of the turned sandy soil is not good, resulting in the soil of the lower layer of the sandy land being turned over and covering the original surface for too short a time, and then it will immediately tilt and flow downward, reducing the effect of the lower layer of the sandy land covering the original surface, and the water and fertilizer of the sandy land cannot be retained and are easily lost.

The electric push rods v24 on both sides operate synchronously to push the lower push plate v21 to descend stably, so that the lower fork tube v26 is inserted into the sandy soil. At this time, the wheat husk mixed organic fertilizer in the mixing box v9 is sprinkled into the sandy soil through the material distribution port v28, the lower guide tube v25 and the lower fork tube v26. The soil properties of the sandy soil are changed by the wheat husk mixed organic fertilizer, the fertility of the sandy soil is improved, and the sandy soil is prevented from being loose and serious water loss.

The wheat husks, corn flour and Youjunkang bacteria are stirred and mixed to form wheat husk mixed organic fertilizer through the guiding downward discharge of the guide mechanism v7. Then, the wheat husk mixed organic fertilizer is completely transferred to the upper end of the discharge mechanism v2 through the two lower guide plates v6 at the bottom of the inner side of the mixing box v9 to be discharged, so as to prevent the wheat husk mixed organic fertilizer from staying in the mixing box v9. In the process of discharge, multiple dividers are set The port v28 corresponds to the lower duct v25 and the lower fork tube v26, which disperses and discharges the wheat husk mixed organic fertilizer group, and the electric push rods v24 on both sides synchronously operate to push the lower push plate v21 to descend stably, so that the lower fork tube v26 is inserted into the sandy soil. At this time, the wheat husk mixed organic fertilizer in the mixing box v9 is sprinkled into the sandy soil through the distribution port v28, the lower duct v25 and the lower fork tube v26. The wheat husk mixed organic fertilizer changes the soil properties of the sandy soil, improves the fertility of the sandy soil, and avoids the sandy soil being relatively loose and serious water loss.
