Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a soil loosening device for cranberry planting. Background Art

[0002] Before planting cranberries, the planting field needs to be loosened. Loosening the soil can break up soil compaction and make soil particles looser, which is conducive to the extension and breathing of the root system. At the same time, loosening the soil can increase the porosity of the soil, improve the aeration of the soil, help the root system absorb oxygen in the air, and promote the healthy growth of the plant.

[0003] When loosening the soil in the planting field, it is also necessary to control the depth of the loosening, that is, a reasonable loosening depth can break the plow bottom layer, and adjust the loosening depth according to the soil type to make the soil more suitable for crop growth. For example, the Chinese utility model patent disclosed by publication number CN217936440U: a loosening device for cranberry planting, the application is installed on the front side of the installation box through a loosening frame through a loosening wheel, and the loosening frame is snap-fitted and installed on the inner end of the load-bearing frame. When the height of the loosening wheel needs to be adjusted, threaded holes of different heights can be selected for installation, which is convenient for adjusting the height of the loosening. However, when the height of the loosening wheel and the crushing wheel is adjusted, since the loosening wheel and the crushing wheel are respectively adjusted in height by means of two loosening frames in conjunction with the pin shaft and the threaded hole, when the height of the loosening wheel or the crushing wheel is adjusted, it is easy to make the loosening wheel or the crushing wheel tilt to one side, thereby increasing the difficulty of fixing the loosening frame. At the same time, the above structure cannot easily adjust the height of the loosening wheel and the crushing wheel. Utility Model Content
