Rotary tiller operation universal joint damage is more common. According to the query; Rotary tiller universal joint damage is mainly caused by improper use; second, the device is not correct; third, the universal joint shaft and bushing are not properly selected. Fourth, there is no timely protection according to the rules; the fifth is that when the ground turns, there is no promotion or no forcible turns.
The method to avoid the damage of the rotary tiller universal joint is as follows:
It is not advisable to use a rotary tiller for plots with many stones; the best use of other implements,
Start and engage the power first; then gradually drop the tillage; make the rotary tiller blade gradually enter the soil,
The length of the universal joint square shaft and the sleeve should be matched with the type of the tiller; if it is too long, the transmission part will be broken in the application; if it is too short, the tiller will come out when it rises.
When the universal joint device is installed; the opening of the clamping fork should be in the same plane; to ensure that the rotation of the cutter shaft is evenly distributed; otherwise, the transmission member is easily damaged.
Smooth protection on demand as required; do not lose oil injection grease at all smooth points; avoid early damage due to dry conflicts,
When the height of the tillage is raised by hydraulic control, the height of the rotary cutter should not exceed 20cm.
You must first promote the tillage when you turn; otherwise you will simply damage the transmission.
In the work; the angle between the square shaft of the universal joint and the plane of the gearbox must not exceed 10Â°; otherwise the transmission power is reduced; and the damage is simple; the angle cannot exceed 30Â° after the tiller is promoted; otherwise, the universal joint is simply damaged.

1,The excellent performance of Fireproof Rock Wool Insulation / Mineral Wool Insulation
The rock wool have higher strength and better elasticity. The folded rock wool board with certain compression resistance has greater drawing strength, and it does not tend to peel off and has greatly improved durability.
2,The Advantage of Fireproof Rock Wool Insulation and Mineral Wool Insulation
1) Small coefficient of heat conductivity and good capability of heating preservation;
2) Excellent fireproof capability, Excellent sound absorption and sound insulation capability;
3) Green building materils and no harm for body;
4) The rock wool has higher and better elasticity;
6)The folded rock wool board with certain compression resistance has greater drawing strength, and it does not tend to peel off and has greatly improved durability.
