Agricultural equipment machine buffer

The invention relates to a buffer device for an agricultural implement machine, in particular to a buffer device for an agricultural implement machine which is provided with a suspension module and has a large swing range of the main pole of the wheel.

The agricultural implement system is used in a mechanized power equipment in agricultural land and orchard to provide users with the effect of saving labor and improving work efficiency. The ground of agricultural land and orchard is different from the generally paved road surface, and most of them have uneven bumps or It is a raised object such as stone. Therefore, the agricultural implement machine must be equipped with a cushioning device to avoid the discomfort caused by the bumping of the vehicle body when the vehicle is moving, or the risk of tilting or even overturning the vehicle body when the projectile is crossed.

As shown in FIG. 4, the existing agricultural implement has a pivoting portion 71 at the bottom of the front side of the vehicle body 70 for connecting a front wheel main rod 80, and the front wheel main rod 80 The two front wheels 90 of the vehicle body 70 are connected to the two sides. When the bumping road section is encountered or the road surface protrusions are encountered, the front wheel main pole 80 swings up and down with respect to the pivoting portion 71 to balance the height difference between the two front wheels 90. The vehicle body 70 is prevented from being directly impacted by the impact, and the left and right sides of the pivoting portion 71 are further provided with a pair of limiting members 72 to prevent the front wheel main rod 80 from swinging excessively and hitting the vehicle body 70 itself.

However, the buffer device of the existing agricultural implement machine causes the front wheel main rod 80 to swing only a small amount due to the pair of the limiting members 72 provided on the pivoting portion 71, and the height difference of the front wheel 90 is balanced to avoid the vehicle body. 70 The effect of direct impact and tilting or even overturning is limited. If the front wheel 90 encounters a large height difference, the vehicle body 70 will still be directly impacted, which may cause tilting or even overturning, and cause a risk of personal injury. The buffer of the machine still has to be improved.

In order to solve the problems encountered in the buffer device of the above-mentioned existing agricultural implement machine, the present invention is pivotally connected to a bottom portion of the vehicle body and can be pivoted up and down, and is pivotally connected to both sides of the main rod member and is opposite to each other. a two-axis rod that swings up and down the main rod member, and further couples the main rod member and the two-axis rod with a second suspension module, and the relative swing of the two-axis rod and the main rod member The second suspension module absorbs part of the impact, effectively improves the efficiency of the buffer device and improves the stability of the agricultural implement when traveling.
