Description

Technical Field

[0001] The utility model relates to the technical field of micro-tillage machine components, in particular to a micro-tillage machine blade. Background Art

[0002] A micro-tiller is a small agricultural machinery equipment used for farmland operations such as plowing, turning and loosening the soil. It is mainly used in small farmlands or horticultural planting areas. It is widely used because of its compact structure, easy operation and wide range of applications. Among them, the blade of the micro-tiller is the key component of the micro-tiller, mainly used for plowing and soil processing, and is usually in an arc or curved shape.

[0003] At present, when the existing micro-tiller blades are in use and there are many stones in the soil, the blade part is prone to damage when colliding with the stones. Most micro-tiller blades basically adopt an integrated design. After damage, they need to be replaced as a whole. In addition, the micro-tiller uses a large number of blades. During the rapid rotation process, when there are many stones, after a collision, multiple blades may be damaged, resulting in increased costs for users. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art that there are many stones and collisions are easy to occur, the blade is easy to be damaged, and the overall replacement cost is high, and a micro-tillage machine blade is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A micro-tiller blade comprises a fixed handle, a first connecting hole is provided at a position near the top of the fixed handle, a second connecting hole is provided at a position near the bottom of the first connecting hole, a blade body is integrally formed at the bottom of the fixed handle, the blade body and the blade are both curved, a protective groove is provided at the top of the blade body, a blade is threadedly connected to the bottom of the blade body, and a cutting edge is integrally formed at the bottom of the blade.

[0007] Preferably, a fixing bolt is provided on the inner side of the protective groove, the fixing bolt is movably sleeved with the blade body, and the bottom of the fixing bolt is threadedly connected with the blade.

[0008] Preferably, the blade is provided with five cutting edges near the bottom, the lengths of the five cutting edges are the same, all of which are 16 mm, and the lengths of the gaps between the five cutting edges increase successively, and the lengths of the gaps between the five cutting edges are all between 21 mm and 24 mm.

[0009] Preferably, a snap-in groove is formed at the bottom of the blade body, and a snap-in protrusion is formed integrally at the top of the blade.

[0010] Preferably, the blade and the snap-fitting protrusion are threadedly connected to the blade body and the snap-fitting groove via fixing bolts, and the fixing bolts are distributed near the left and right sides and near the middle of the blade body.

[0011] Preferably, the radii of the first connecting hole and the second connecting hole are both 10.5 mm, the center distance between the first connecting hole and the second connecting hole is 70 mm, the overall length of the fixed handle and the blade body is between 158 mm and 160 mm, and the overall height of the fixed handle and the blade body is between 220 mm and 222 mm.

[0012] Compared with the prior art, the utility model provides a micro-tillage machine blade having the following

[0013] Beneficial effects:

[0014] 1. The blade of the micro-tillage machine is equipped with a blade and a protective groove. When the blade is worn or damaged due to soil with a lot of stones, only the blade needs to be replaced instead of the entire blade body, which saves costs. The blade can be replaced, which is conducive to customization according to different crops and soil conditions to meet different agricultural needs. More types of blades can adapt to the planting requirements of different crops and the tillage effects of different soils, thereby improving the flexibility of equipment use.

[0015] 2. The micro-tillage machine blade is provided with a protective groove and a snap-in protrusion. During use, the snap-in protrusion and the snap-in groove are snapped together, which makes it easy to quickly position the equipment and install the fixing bolts. The opening of the protective groove reduces the erosion of the fixing bolts by soil and water, and increases the service life of the fixing bolts. At the same time, during use, the fixing bolts are buried in the inner side of the protective groove, which reduces the influence of the external environment on the fixing bolts and ensures the stability of the equipment. The protective groove is in a winding downward state as a whole, which is convenient for cleaning the inner side of the protective groove with water. BRIEF DESCRIPTION OF THE DRAWINGS
