[0002] A tillage machine is a farm tool for tilling the land.

[0003] The tillage machine includes a frame, and a tillage knife assembly is further installed on the frame. The tillage knife assembly includes a frame, a tillage knife shaft is installed in the frame, and a plurality of tillage knives are installed on the tillage knife shaft. A driving wheel is also installed on the tillage knife shaft. During use, the driving wheel is connected to a driving power, the tillage knife shaft rotates, and drives the tillage knives to rotate, so as to realize tillage of the field.

[0004] In the prior art, there is only one set of tillage knife assemblies on the tillage machine, that is, during tillage, the tillage machine in the prior art only tills the field once, having the disadvantages of poor flatness of the surface layer of the field and large soil clods on the surface of the field, and cannot meet the requirements of some plantings. Summary of the Invention

[0005] The purpose of the utility model is to address the above-mentioned disadvantages and provide a tillage machine with a flatter surface and smaller soil clods during tillage, which can meet some tillage requirements - a tillage machine with two tillage knife assemblies.

[0006] The technical solution of the utility model is realized as follows: A tillage machine with two tillage knife assemblies includes a frame, and a tillage knife assembly is further installed on the frame. The tillage knife assembly includes a frame, a shield is installed on the frame, a tillage knife shaft is installed in the frame, and a plurality of tillage knives are installed on the tillage knife shaft. A driving wheel is also installed on the tillage knife shaft. The feature is that there are two sets of tillage knife assemblies, namely a front tillage knife assembly installed in front of the frame and a rear tillage knife assembly installed behind the frame. The tillage knives in the front tillage knife assembly are front tillage knives, and the tillage knives in the rear tillage knife assembly are rear tillage knives. The length of the rear tillage knives is less than the length of the front tillage knives. The density of the rear tillage knives is greater than the density of the front tillage knives.

[0007] Furthermore, the frame of the front tillage knife assembly is a front frame, the frame of the rear tillage knife assembly is a rear frame. The front frame and the rear frame are connected by a connecting rod. The front end of the connecting rod is connected to the front frame by a front hinge shaft. The rear end of the connecting rod is connected to the rear frame by a rear hinge shaft.

[0008] Furthermore, the drive wheel of the front tillage knife assembly is a front drive wheel, and the drive wheel of the rear tillage knife assembly is a rear drive wheel. The front drive wheel and the rear drive wheel are connected to a common power source. Under the action of the common power source, the circumferential speed of the rear drive wheel is greater than that of the front drive wheel.

[0009] The beneficial effects of the present utility model are as follows: Such a tillage machine has the advantages that the surface of the cultivated field is flatter and the surface soil blocks are smaller, which can meet some tillage requirements. Description of the Drawings

Detailed Embodiments

[0014] The present utility model will be further described below in conjunction with the drawings.

[0015] As Figure 1 , 2 shown, a tillage machine with a double tillage knife assembly includes a frame 1. A tillage knife assembly 2 is further installed on the frame. The tillage knife assembly includes a frame 21. A shield 22 is installed on the frame. A tillage knife shaft 23 is installed inside the frame. A plurality of tillage knives 24 are installed on the tillage knife shaft. A drive wheel 25 is further installed on the tillage knife shaft. It is characterized in that: There are two sets of tillage knife assemblies, namely a front tillage knife assembly 26 installed in front of the frame and a rear tillage knife assembly 27 installed behind the frame. The tillage knives inside the front tillage knife assembly are front tillage knives, and the tillage knives inside the rear tillage knife assembly are rear tillage knives. The length of the rear tillage knife is less than that of the front tillage knife. The density of the rear tillage knife is greater than that of the front tillage knife.

[0016] With the above settings of the present utility model, during use, the field is first cultivated by the front tilling knife assembly, and then the rear tilling knife assembly is used to cultivate the field. Since the length of the rear tilling knife is less than that of the front tilling knife, it can be realized that the rear tilling knife only processes the surface soil formed by the front tilling assembly, that is, further break up the large chunks on the soil surface. Since the density of the rear tilling knife is greater than that of the front tilling knife, it can be realized that the surface of the field is cultivated more smoothly, achieving the purpose of the present utility model.

[0017] Furthermore, the frame of the front tilling knife assembly is the front frame 211, and the frame of the rear tilling knife assembly is the rear frame 212. The front frame and the rear frame are connected by a connecting rod 3. The front end of the connecting rod is connected to the front frame by a front hinge shaft 31, and the rear end of the connecting rod is connected to the rear frame by a rear hinge shaft 32.

[0018] With the above settings of the present utility model, it also has the advantage of better flexibility of the entire tillage machine.

[0019] In one technical solution, as Figure 3 shown, the connecting rod is in two sections, and the two sections are connected by a third hinge shaft 33.

[0020] Furthermore, the driving wheel of the front tilling knife assembly is the front driving wheel, and the driving wheel of the rear tilling knife assembly is the rear driving wheel. The front driving wheel and the rear driving wheel are connected to a common power source. Under the action of the common power source, the circumferential speed of the rear driving wheel is greater than that of the front driving wheel.

[0021] With the above settings of the present utility model, during use, that is, the rotation speed of the rear tilling knife is faster, and it can better achieve a smoother leveling of the land.

[0022] The above are only specific embodiments of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
