Description

TECHNICAL FIELD

[0001] The present application relates to a roller type quicklime circle spreader for peanut planting, which is used for spreading quicklime around peanut seedlings during peanut planting and belongs to the field of agricultural production. In particular, the present application relates to a circle spreader, which is capable of quickly and conveniently spreading quicklime around the peanut seedlings by rotating a roller body to make the through hole on the center rotating core and the powder outlet hole on the roller body correspondingly communicate, and by cooperating with a plugging sleeve to make the quicklime powder be circularly spread around the peanut seedlings, thereby avoiding the quicklime powder from splashing onto the seedlings. BACKGROUND

[0002] Before planting peanuts, quicklime is usually spread in the soil to change the soil acidity and increase the content of calcium ions, and to eliminate pests. However, after the peanuts are planted, the peanuts are still susceptible to pests. Therefore, a circle of quicklime is usually spread around the peanut seedlings after planting according to the severity of the pests. The traditional spreading method is to manually spread the quicklime, which has low spreading efficiency, uneven spreading range, and is prone to cause burns on the hands. In addition, the quicklime should not be splashed onto the peanut seedlings during spreading to avoid burning the tender leaves of the seedlings, which greatly increases the operation difficulty of spreading the quicklime around the peanut seedlings after planting.

[0003] Publication No. CN206674469U discloses a quicklime powder fertilizing device, which has a flexible rope with a length of at least 1.5 meters fixed at one end of a handle, and a mesh-shaped round shell-shaped net bag is fixedly connected at the end of the flexible rope. A sealing plug is arranged at the opening of the net bag. The quicklime powder fertilizing device can only be used for pre-planting spreading, and it is easy to spread the quicklime powder onto the tender leaves of the seedlings and cause burns when spreading after the peanut seedlings grow. SUMMARY

[0004] In order to improve the above situation, the present application provides a roller type quicklime circle spreader for peanut planting, which is capable of quickly and conveniently spreading quicklime around the peanut seedlings by rotating a roller body to make the through hole on the center rotating core and the powder outlet hole on the roller body correspondingly communicate, and by cooperating with a plugging sleeve to make the quicklime powder be circularly spread around the peanut seedlings, thereby avoiding the quicklime powder from splashing onto the seedlings.

[0005] The application discloses a drum type raw lime circle spreader for peanut planting, which is composed of a spreading device and a moving device. Advantages

[0006] I. The raw lime can be evenly spread around the peanut seedlings in a ring shape, and the raw lime powder can be prevented from splashing on the peanut seedlings.

[0007] II. The raw lime can be spread by the spreading device instead of manually grabbing and spreading by hands, so that the harm to the hands is reduced.

[0008] III. The structure is simple, convenient and practical.

[0009] IV. The cost is low, and the application is convenient to popularize. BRIEF DESCRIPTION OF DRAWINGS
