Description

Anti-collision mechanism of farm screed with screed

The present invention relates to a mechanism attached to a leveler for simultaneously smoothing the soil after flattening the agricultural land, and is a pivoting joint between the smoothing member and the leveler through two mutual pivots. And the two pieces are pivoted in a folded state, so that the smeared parts can be protected from unimpeded retraction when they are collided.

For example, the patent No. 439396 of the publication is a screeding device equipped with a cultivating machine, mainly on a transmission device behind the agricultural vehicle carrier, and dragging a smear that can smooth the soil of the agricultural land, and the smear is Firstly, a second link is pivotally connected with a first link, and the other end of the first link is fixed to the transmission device, so that the weight of the wiper plate itself and the swing of the second link are enabled. The effect is to flatten the mud of the agricultural land and achieve the effect of smoothing the farmland.

For example, as disclosed in the patent of M367572, it is also a screed auxiliary mechanism which is installed on the leveling device installed behind the traction machine, and has a flat structure which is in the leveling device. There is a plurality of pivoting seats, and each of the pivoting seats is provided with a backward extending extending rod, and each of the protruding rods is provided with a specific weighting leveling group, the purpose of which is to utilize the above design when the traction machine utilizes When the flat device completes the soil preparation, the protruding soil block can be further smoothed by the smoothing structure, and the effect of the traction machine on the agricultural land preparation can be improved.

However, the smears or smears of the smeared structures described above are connected to the transmission or the leveling device through a connecting rod or a stretching rod, so that the smearing or smearing group can be uplifted along with the fluctuation of the agricultural land. Swinging down, but the wiper or smoothing group can only swing up and down, if it is behind the implement When reversing and accidentally hitting the field, the reaction force of the impact will only be caused by the connecting rod (or the rod) connecting the wiper or the smoothing group, and the smearing or smoothing group will not Will lift up, which will cause damage to the wiper or smoothing group, or bending deformation of the connecting rod (or the rod), and even breakage at the joint.

The reason is that in order to improve the smeared device, there may be a collision and damage when the machine moves backwards. The present invention provides a collision avoidance mechanism, that is, between the smearing member and the screed. The connecting members composed of the connecting pieces are joined together, and the two connecting pieces are pivoted together to make the two parts unobstructed when the flattening parts are accidentally hitting the field by the back of the vehicle. The folding allows the smoothing component to be smoothly retracted, thereby avoiding unnecessary accidental damage to the screed.

Therefore, the technical solution adopted by the present invention for solving the problem is that it is attached to the screed and dragged to the rear screeding member, and the screeding member and the screed are connected by an array connecting member. The improvement is that the connecting member is a two-piece member that is pivotally fixed to the corresponding inner end, and the opposite outer ends of the two connecting members are respectively pivoted on the corresponding leveler and the smoothing member, and two The pivot of the piece is folded.

In the above solution, the corresponding ends of the two connected pieces are pivoted together adjacent to each other, and the end ends of the corresponding ends of the two connected pieces are respectively convexly disposed to abut on the side of the corresponding connecting piece. The abutment.

Therefore, through the pivoting manner of the above-mentioned two-piece folding member, when the squeezing member is impacted when retracting, the two pieces can be folded smoothly and unimpeded, so that the screeding member is retracted. Minimizes the impact of the smeared parts, which in turn allows the smeared parts and other joints to be protected from unnecessary losses.

Figure 2 is a partially enlarged schematic view of Figure 1A.

Figure 3 is a side elevational view of the present invention.

Figure 4 is a partially enlarged schematic view of the side of the present invention.

Fig. 5 is a schematic view of the cushioning and retracting in the collision of the present invention.

Please refer to FIG. 1 to FIG. 4, the new screed device is a device attached to the rear of a flattener 1 and is towed, which is mainly a smearing part 2 which can be pressed on the ground, and Between the smoothing member 2 and the leveler 1, the two are connected together by the array connecting member 3, and the connecting members 3 further comprise connecting members 31, 32 which are pivotally fixed together, and the connecting members The outer end of the 31 is pivotally fixed to the leveler 1, and the connecting member 32 is fixedly coupled to the smoothing member 2, so that the smoothing member 2 is dragged behind the leveler 1.

In addition, the corresponding inner end of each of the two connecting members 31, 32 is such that the adjacent ends of the two ends are pivoted together, and the opposite ends of the two ends are respectively convexly provided with corresponding abutting portions 311, 321 and The abutting portions 311, 321 can be abutted against the side edges of the corresponding connecting members 31, 32, thereby pivoting the two connecting members 31, 32.

Therefore, when the screed device is towed with the screed 1, the flatness of the agricultural land leveling can be improved, but if the vehicle moves backwards as shown in FIG. 5, if the screed 2 is accidentally hit In the case of Ueda, due to the pivotal relationship between the two pieces 31, 32, the two pieces 31, 32 will be folded relatively easily without any effort, that is, the smoothing member 2 can be retracted without any hindrance. Further, the smoothing member 2, the two and the connecting members 31, 32 are not deformed and damaged by the impact, and the screed device has a collision prevention mechanism and is timely protected from unnecessary damage.

Although the above embodiments have disclosed and detailed embodiments of the present invention, These are all known to those who are familiar with the technology, and the various changes in the various types and methods they do should not deviate from the spirit and scope of this new type.
