Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery, and in particular relates to a knife roller of a strip tiller capable of being installed with a reclamation knife and an installation method thereof. Background Art

[0002] The strip tillage machine is an indispensable machine for conservation tillage accepted by the majority of farmers, and plays a key role in promoting conservation tillage agronomy. Existing strip tillage machines are equipped with seven-character knives, and there is a knife magazine with a hole on the knife disc. This seven-character knife is suitable for stubble removal and rotary tillage of general plots. However, for plots with small stones or sandy land, the seven-character knife is seriously worn and cannot be competent. At this time, it is more appropriate to use a reclamation knife, but the handle of the reclamation knife has two mounting holes, and the existing strip tillage machine knife disc cannot be installed, which limits the scope of use of the strip tillage machine. In view of the above situation, the present invention provides a strip tillage machine knife roller that can be equipped with a reclamation knife, which can solve the above problem. The present invention ensures that both the seven-character knife and the reclamation knife can be used on the strip tillage machine, so that the strip tillage machine can be operated on ordinary plots and on plots with more small stones and sandy land, increasing the practicality of the strip tillage machine. SUMMARY OF THE INVENTION

[0003] The object of the present invention is to provide a knife roller of a strip tiller which can be equipped with a reclamation knife, so that the strip tiller can be equipped with a seven-shaped knife or a reclamation knife, so as to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: A strip tiller knife roller capable of installing a reclamation knife comprises: a knife magazine, a knife disc, a knife disc hole, a knife magazine hole, a seven-character knife, a seven-character knife handle mounting hole, a left-handed reclamation knife, a reclamation knife handle mounting hole, a fixing bolt, a right-handed reclamation knife, a knife roller shaft, a first knife disc, a second knife disc, a third knife disc, a fourth knife disc, and a fifth knife disc, characterized in that the surfaces of the knife magazine and the knife disc web are flush after welding, which can fit closely with the reclamation knife surface. Further, based on the original knife magazine hole of the knife magazine, a knife disc hole is also set at an appropriate position of the knife disc web, and these two holes are combined for the installation of the reclamation knife.

[0005] The tool magazines of the first, second, fourth and fifth cutter discs are further aligned in the axial direction of the cutter roller shaft and are respectively welded to appropriate positions of the cutter roller shaft, while the tool magazine of the third cutter disc is welded to an appropriate position of the cutter roller shaft at an angle of 30 degrees to the tool magazines of the other cutter discs.

[0006] A method for installing a reclaiming knife using a strip tiller knife roller on which a reclaiming knife can be installed, the method comprising the following steps:

[0007] Step 1. Evenly install three left-leaning reclamation knives on the first knife disc starting from the left side of the knife roller;

[0008] Step 2. Evenly install three left-leaning knives on the second knife disc from the left side of the knife roller, and stagger them 60 degrees with the knives on the first knife disc;

[0009] Step 3. Install two left-leaning and two right-leaning knives evenly and alternately on the third knife disc from the left side of the knife roller, and stagger them 30 degrees with the knives on the second knife disc;

[0010] Step 4. Evenly install three right-leaving knives on the fourth knife disc from the left side of the knife roller, and stagger them 30 degrees with the knives on the third knife disc;

[0011] Step 5. Evenly install three right-handed clearing knives on the fifth knife disc from the left side of the knife roller, and stagger them 60 degrees with the clearing knives on the fourth knife disc.

[0012] In the further described step 1, not limited to 3 left-handed clearing knives, 4 left-handed clearing knives may also be installed.

[0013] In the further described step 1, it is not limited to the left-leaning blade, but a right-leaning blade can also be installed. When the right-leaning blade is installed, the second blade disc is also installed with a right-leaning blade, and the fourth (fifth) blade disc is correspondingly changed to a left-leaning blade. In the further described step 1, if the first (second) blade disc is installed with a right-leaning blade, and the fourth (fifth) blade disc is installed with a left-leaning blade, the tillage width becomes narrower to adapt to different tillage widths.

[0014] In the further described step 3, on the third cutter disc, not limited to the evenly staggered installation of 2 left-handed clearing knives and 2 right-handed clearing knives, 3 left-handed clearing knives and 3 right-handed clearing knives may also be installed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The practicability of the strip tiller is greatly improved. In the past, the strip tiller was not suitable for operation on land with many small stones or sandy land. With the present invention, the strip tiller can be operated with a reclamation blade.

[0017] 2. The strip tiller can use the reclamation knife, which is wear-resistant and greatly reduces the number of maintenance and knife replacement;

[0018] 3. Make the tillage width of the strip tiller variable to meet different tillage width requirements. BRIEF DESCRIPTION OF THE DRAWINGS
