DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] As Figure 1 and Figure 2 shown, this embodiment provides a harrowing and soil-loosening mechanism, which includes a connecting frame 1, a whole-foundation base 4, and a whole-landing component 5; the connecting frame 1 includes a cross beam 1.1 and an inverted "V"-shaped support frame 1.2 fixed on the cross beam 1.1. A connecting ear 2 is fixed at each end of the cross beam 1.1 of the connecting frame 1 and at the top of the support frame 1.2 for connecting a traction frame. Through the traction frame, the present invention is connected to an agricultural power device. For example, a tractor drives the present invention to run on the land through the traction frame.

[0020] Both ends of the cross beam 1.1 of the connecting frame 1 are respectively connected to the front end of the whole-foundation base 4 through a connecting member 3. The connecting member 3 is two interlocking chain links. The upper chain link is connected to the cross beam 1.1 by passing through a pin, and the lower chain link is connected to the whole-foundation base 4 by passing through a pin; a support beam 1.3 perpendicular to the cross beam 1.1 is fixed at the top of the support frame 1.2. A reinforcing rod 1.4 is fixed between the support beam 1.3 and the cross beam 1.1 to play a role in strengthening the support; a connecting sleeve 12 is sleeved at the end of the support beam 1.3, and a traction chain 13 connected to the end of the whole-foundation base 4 is fixed on the connecting sleeve 12; the whole-foundation base 4 is flexibly connected to the connecting frame 1 through the traction chain 13 and the chain link, which not only effectively connects the connecting frame 1 and the whole-foundation base 4, but also ensures that the whole-foundation base 4 can buffer upward displacement after being stressed, realizes ground-following movement, avoids damage, and extends its service life.

[0021] The structure of the whole-foundation base 4 includes a square frame formed by welding four angle steels 4.1. Steel beams 4.2 arranged vertically and horizontally are welded between the four angle steels 4.1. A bracket 8 is fixed on the top of the whole-foundation base 4, and a counterweight object 9 is placed on the bracket 8; in this embodiment, the bracket 8 is a mesh structure welded by steel bars, and the counterweight object 9 is a woven bag filled with sand and soil; in actual use, according to the on-site situation, a certain weight of counterweight object 9 is placed on the bracket 8 to ensure that the harrowing teeth 7 can effectively penetrate into the soil for efficient harrowing.

[0022] A whole-landing component 5 is swingably arranged at the tail of the whole-foundation base 4. The whole-landing component 5 includes an intermediate shaft 5.1 and a plurality of whole-landing discs 5.2 fixed at intervals along the axis of the intermediate shaft 5.1;

[0023] Both ends of the intermediate shaft 5.1 are respectively connected to the integral foundation base 4 through the connecting beams 6. A sliding sleeve 10 sleeved on the intermediate shaft 5.1 is fixed at one end of the connecting beam 6, and the other end of the connecting beam 6 is connected to the integral foundation base 4 by passing through a pin shaft. During the movement of the integral foundation base 4 under force, the connecting beam 6 drives the intermediate shaft 5.1 to swing slightly around the pin shaft. An "L"-shaped limiting frame 11 covering the connecting beam 6 is fixed on the integral foundation base 4, which plays an effective limiting role for the connecting beam 6.

[0024] Three rows of harrowing teeth 7 arranged in a left-right staggered manner are fixed on the bottom surface of the integral foundation base 4. Each row of harrowing teeth 7 is arranged along the axial direction of the intermediate shaft 5.1, and the rhizomes of crops underground are effectively harrowed and loosened by the harrowing teeth 7.

[0025] The integral discs 5.2 are coaxial and perpendicular to the intermediate shaft 5.1. The outer diameters of the integral discs 5.2 are the same. A number of soil loosening ribs 5.3 arranged circumferentially along the intermediate shaft 5.1 are fixed between the edges of every two adjacent integral discs 5.2. The hardened soil clods can be crushed by the soil loosening ribs 5.3 to achieve the purpose of soil loosening. A number of soil loosening ribs 5.3 between every two adjacent integral discs 5.2 form a group. Each soil loosening rib 5.3 in each group is inclined in the same direction with respect to the axis of the intermediate shaft 5.1, and the inclination directions of the soil loosening ribs 5.3 in adjacent groups are opposite, so as to avoid shifting the loosened soil in the same direction and ensure that the land is evenly flat after land preparation. The structure of the utility model is simple, is made according to the actual land area, has low cost and strong practicability, and is beneficial to improving the operation efficiency.
