Description

Technical Field

[0001] The utility model relates to the technical field of riding micro-tillage machines, in particular to a safety frame for riding micro-tillage machines. Background Art

[0002] The wheelbase of the riding micro-tiller (the lateral distance between the front and rear wheels of the riding micro-tiller) is small, the center of gravity is high, and the machine weight is light. When the staff operates the riding micro-tiller to go downhill or turn, or travel on uneven terrain, due to improper operation (such as the riding micro-tiller traveling at a high speed, unfamiliarity with the performance of the riding micro-tiller), the riding micro-tiller loses balance during driving, causing the riding micro-tiller to tip over (such as tipping over forward or backward, and rolling over sideways). When the riding micro-tiller tips over, especially when tipping over forward or backward, after one end of the riding micro-tiller touches the ground, the staff immediately contacts the ground, and then the other end of the riding micro-tiller also contacts the ground. Since the height difference between the front and rear ends of the riding micro-tiller is not large, the riding micro-tiller is close to the ground after tipping over, and the staff is pressed between the riding micro-tiller and the ground and cannot move. Now there is an urgent need for a riding micro-tiller safety frame that can provide protection for the staff when the riding micro-tiller tips over. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a safety frame for a ride-on micro-tiller, which can slow down the tipping speed of the ride-on micro-tiller body when the ride-on micro-tiller body tips over, thereby slowing down the speed at which the staff contacts the ground, and also provides a protection area for the staff to prevent the staff from being unable to move after the ride-on micro-tiller body tips over.

[0004] The technical solution adopted by the utility model is as follows: a safety frame for a riding micro-tillage machine, comprising a safety frame installed on a body of the riding micro-tillage machine, wherein the safety frame provides protection for workers when the body of the riding micro-tillage machine overturns.

[0005] Compared with the prior art, the beneficial effects of the present invention are:

[0006] The safety frame of the utility model can contact the ground when the riding micro-tillage machine body falls over forward or backward, thereby increasing the contact area between one end of the riding micro-tillage machine body and the ground, changing the tilting angle of the riding micro-tillage machine body, slowing down the tilting speed of the riding micro-tillage machine body, and thus slowing down the speed at which the staff contacts the ground, and also makes one end of the riding micro-tillage machine body higher than the other end of the riding micro-tillage machine body under the support of the safety frame. The ground, the safety frame and the riding micro-tillage machine body enclose a triangular protection area, and the staff are prevented from being pressed and unable to move in the protection area. The triangle has stability and can also prevent the riding micro-tillage machine body from continuing to tip over; or provide a buffer when the riding micro-tillage machine body tips over (such as tipping over), preventing the staff from being injured by rapid and direct contact with the ground, and preventing the parts on the riding micro-tillage machine body from being directly damaged by impacting the ground.

[0007] As a preferred embodiment of the utility model, the safety frame is located between the engine of the riding micro-tillage machine body and the front gearbox of the riding micro-tillage machine body, and is connected to the front gearbox of the riding micro-tillage machine body.
