Description

Technical Field

[0001] This utility model relates to the technical field of soil loosening equipment, specifically a soil loosening blade for a rice planting soil loosening machine. Background Technology

[0002] Rice is one of the world's most important food crops, and the looseness of the soil has a significant impact on its growth and development. Good soil looseness can promote the growth and development of rice roots, improve the efficiency of water and nutrient absorption, and thus increase the yield and quality of rice.

[0003] Existing soil loosening tools are usually cast as a single piece. After prolonged use, the tools wear out and require maintenance. In more serious cases, the entire tool needs to be replaced after it is completely damaged, resulting in a waste of resources, reduced work efficiency, and higher costs. Therefore, the existing technology has technical defects and needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soil-loosening blade for a rice planting soil-loosening machine to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a soil loosening blade for a rice planting soil loosening machine, including a transmission roller with a transmission shaft longitudinally arranged in the middle. The outer surface of the transmission roller is provided with a plurality of longitudinally spaced mounting holes. A base is fitted around each set of mounting holes. The base is provided with a plurality of protrusions around its circumference. A blade mounting ring is fitted around the outer side of the base. A blade holder is provided on the outer surface of the blade mounting ring corresponding to the position of the protrusion. A blade head is installed through the blade holder. The blade mounting ring, the base and the blade head are bolted together in sequence from the outside to the inside. The blade mounting ring is bolted to the protrusion.

[0006] Preferably, a first positioning hole corresponding to a mounting hole is provided between each adjacent protrusion, and a first fixing hole extending inward is provided on one side of each protrusion;

[0007] Each adjacent tool holder is provided with a second positioning hole corresponding to the first positioning hole, and one side of each tool holder is provided with a second fixing hole corresponding to the first fixing hole.

[0008] Preferably, the mounting hole, the first positioning hole, the second positioning hole, the first fixing hole, and the second fixing hole are all threaded holes.

[0009] Preferably, the second positioning hole, the first positioning hole and the mounting hole arranged sequentially from the outside to the inside are threadedly connected by a bolt extending into the mounting hole, and the second fixing hole and the first fixing hole arranged sequentially from the outside to the inside are threadedly connected by a bolt extending into the first fixing hole of the protrusion.

[0010] Preferably, the upper surface of the tool holder has a protruding end in the middle, and the protruding end has a first pin hole that is laterally connected in the middle, through which the tool head is installed.

[0011] Preferably, the cutter head has an open bottom and is hollow, and there are second pin holes on both sides of the cutter head corresponding to the first pin hole, with a positioning pin nested between the first pin hole and the second pin hole.

[0012] Preferably, the cutter head is an L-shaped cutter head formed by bending.

[0013] The beneficial effects of this utility model are as follows:

[0014] By disassembling the soil tamper into multiple assembleable components, including a drive roller, base, blade mounting ring, and blade head, and multiple mounting holes arranged longitudinally and circumferentially around the drive roller serve as fixed points, each on which a base and blade mounting ring are installed sequentially from the inside out. The blade mounting ring also has a blade holder, through which a detachable blade head is mounted. Furthermore, the blade mounting ring, base, and drive roller are all fixedly connected by bolts, making disassembly and assembly convenient. Each base, blade mounting ring, and blade head constitutes an independent set of blades. During use, if any set of independent blades on the drive roller becomes worn or damaged, it can be disassembled and replaced, avoiding the waste of resources that would otherwise require replacing the entire set after damage, and saving manpower and resources.
