Safe supporting device used for maintenance of rotary cultivators

Abstract

The invention discloses a safe supporting device used for the maintenance of rotary cultivators. The supporting device includes a base plate; the two sides of the base plate are connected to stable mechanisms; the top of the base plate is fixedly connected to two jacks; the tops of the jacks are fixedly connected to a placing plate; the top of the placing plate is provided with a limit frame; thetop of the limit frame is provided with multiple screw holes; the inner sides of the screw holes are connected to screws I in a threaded manner; the bottoms of the screws I are fixedly connected to pressing plates; the top surface of the placing plate is provided with multiple air vents; a cavity II is arranged inside the placing plate and located in a cavity I; the bottom of the cavity II is provided with a ventilation channel; and an air pump is arranged at the bottom of the placing plate, and the input end of the air pump is connected to the ventilation channel. The beneficial effects of the supporting device are as follows: the slipping of a rotary cultivator on the supporting device can be greatly avoided; and through the volume of the rotary cultivator, the cooperation of multiple sets of supporting structures can be adopted, so that limitations can be reduced.

Description

technical field [0001] The invention relates to the technical field of rotary tillers, in particular to a safety support device for maintenance of rotary tillers. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, which is convenient for the operation of the seeder and provides a good seed bed for later sowing. [0003] If the rotary tiller is damaged or the blades are worn during use, it needs to be repaired and maintained. In the process of repairing and replacing the blades of the rotary tiller, it is generally necessary to use the power of the tractor to lift the body for easy operation. During the maintenance process, if the tractor is misoperated by someone or the power mechanism breaks down, the body of...

[0003] If the rotary tiller is damaged or the blades are worn during use, it needs to be repaired and maintained. In the process of repairing and replacing the blades of the rotary tiller, it is generally necessary to use the power of the tractor to lift the body for easy operation. During the maintenance process, if the tractor is misoperated by someone or the power mechanism breaks down, the body of the rotary tiller is likely to fall suddenly, causing a safety accident. Chinese Patent No. CN 205266153 U discloses a safety support device for a rotary tiller, which can support Rotary tiller, so as to facilitate the maintenance and operation of the rotary tiller, avoiding the sudden drop of the rotary tiller, but the existing rotary tiller has different sizes, and it is inconvenient to use the integral support device for different volumes of rotary tiller The support operation of the rotary tiller has great limitations, but the split support device has poor integrity, and may fall apart during support, causing the rotary tiller to fall. In addition, it is troublesome to fix the rotary tiller for different sizes. , and if there is slippage at the connection between the rotary tiller and the support device during support, it will also cause the rotary tiller to fall, resulting in a safety accident
