Selection criteria and suggestions of knife set of Chongqing micro cultivator
Source:dffjb.cn Release time:2021/11/13 11:13:27
The knife group of micro tillage machine mainly includes deep tillage knife, dry land tillage knife, wetland machete and compound machete. The selection of knife group of micro cultivator can be based on the application field; Power, tillage width and depth of supporting units; Raw materials are selected from these three aspects.
1、 Select the knife group according to the application place of the micro cultivator
1. If it is used for subsoiling and pioneering in dry land with less weeds, the deep ploughing knife group should be selected; If it is used for dry land, dry land, sandy land, wasteland, greenhouse operation, etc. with soft soil, the dry land tillage knife group shall be selected.
2. If it is used for wetland rotary tillage with less weeds or rice pile field with hard mud feet, the wetland machete group shall be selected;
3. If it is used in rice pile field with hard mud feet, wetland with soft soil or shallow water field and bubble field with weeds, the compound machete group shall be selected
4. If it is used for shallow paddy fields with soft soil feet or the crushed soil used for cultivated fields is flat, paddy field wheel shall be selected:
In addition, the wetland machete group is also used for dry land cultivation with soft soil. However, it is suggested to select the customary knife group according to different soil, which can not only obtain good cultivation quality, but also reduce the damage of the knife.
2、 Select the cutter set according to the power, tillage width and depth of the supporting unit
Generally speaking, the larger the rotating diameter of the knife group, the deeper the tillage depth, and the greater the power consumption; The larger the tillage width of the knife group, the greater the power consumption. In addition, the large torque and other factors that the gearbox gear can bear should also be considered. Because there is no practical theoretical or empirical formula for the force analysis of the cutter set, the manufacturer of the supporting unit should select the cutter set according to the planning experience or experimental research. For ordinary users, try to select the original type of knife set of the manufacturer to avoid the phenomenon of "small horse pulling cart and big horse pulling cart".
3、 Select knife set according to raw materials
In the process of application, the failure phenomena are blade cracking, tool handle falling off, tool set weldment desoldering, corrosion and so on. In order to reduce the occurrence of these phenomena, the blade of the knife set is forged with 65Mn steel and made by heat treatment, and the shaft and handle of the knife set are made of 45 steel with firm welding
