Technical Field

[0001] This utility model relates to the field of tractor technology, specifically to a quick-connect device for tractor implements. Background Technology

[0002] Tractors are one of the core pieces of equipment in modern agricultural mechanization. They are mainly used for farmland cultivation and crop transportation. When using a tractor for cultivation, tillage implements are required. The tillage implements need to be fixed to the rear of the tractor. The implements and tractor need to be connected and fixed together. A tractor-implement quick-connect device is required for this connection.

[0003] Tractors typically have three tie rods on the rear side for connecting implements. These three tie rods mainly consist of an upper tie rod and two lower tie rods on the left and right sides. During connection, the three tie rods are fixed to the implement. There are many existing tractor and implement models, resulting in differences in the model and position of the connecting rods on the tractor and implement. This makes it difficult to quickly connect and use different models of implements with tractors. Therefore, those skilled in the art provide a tractor-implement quick connection device to solve the problems mentioned in the background art. Utility Model Content

The support assemblies are arranged symmetrically on the left and right sides. A vertical steel frame is fixedly installed on the top of each of the two support assemblies. Multiple adjustment components for adjustment are slidably connected to the outer side of each vertical steel frame and the support assembly. One adjustment component is slidably installed on the outer side of each vertical steel frame. Two adjustment components are slidably connected to the outer side of the support assembly on the front and rear sides of each vertical steel frame. A fixing knob is threadedly connected to the outer side of each adjustment component through a support sleeve. A docking component for connection is movably installed on the outer side of each of the multiple adjustment components.

By rotating the fixing knob 33, the adjusting component 3 can be moved outward, which facilitates the movement of the adjusting component 3. By sliding the adjusting components 3 on the outside of the vertical steel frame 2 and the support component 1 up and down and forward and backward, the positions of multiple adjusting components 3 can be adjusted, and the positions of multiple docking components 4 can be adjusted simultaneously. By adjusting the multiple docking components 4 according to the positions of the multiple tie rods of the tractor, the multiple adjusting components 3 can be fixed between the support component 1 and the vertical steel frame 2 by rotating the fixing knob 33, and the multiple docking components 4 can be aligned with the multiple tie rods on the tractor. The multiple docking components 4 facilitate quick connection with the multiple tie rods of the tractor and facilitate connection and fixation with implements.

[0017] As one implementation method in this embodiment, please refer to Figure 1 - Figure 3 As shown, the support assembly 1 includes a longitudinal steel frame 11, and two vertical steel frames 2 are respectively fixedly connected to the top of the two longitudinal steel frames 11 and are perpendicular to the longitudinal steel frames 11. The longitudinal steel frames 11 allow the adjustment assembly 3 to slide back and forth easily, while simultaneously providing fixed support for the vertical steel frames 2.

[0018] As one implementation method in this embodiment, please refer to Figure 1 - Figure 3As shown, the two support components 1 and the two vertical steel frames 2 are fixedly connected by multiple connecting brackets 12, and the two vertical steel frames 2 are parallel to each other in the left and right positions. The connecting brackets 12 can connect and fix the two vertical steel frames 2, and simultaneously connect and fix the two support components 1.

[0019] As one implementation method in this embodiment, please refer to Figure 1 - Figure 3 As shown, each support component 1 has multiple fixing holes 13 on its top and on the front side of the vertical steel frame 2, and one end of each fixing knob 33 extends into the inside of a fixing hole 13. By extending the fixing knob 33 into the inside of the fixing hole 13, the adjusting component 3 can be supported and fixed, preventing the adjusting component 3 from sliding.

[0020] As one implementation method in this embodiment, please refer to Figure 2 - Figure 5 As shown, each adjustment component 3 includes a sliding sleeve 31 and a support sleeve 32 fixedly installed on the outside of the sliding sleeve 31. A threaded sleeve 35 is fixedly installed on the inner side of each support sleeve 32. Each fixing knob 33 is located inside a threaded sleeve 35 and is threadedly connected to the threaded sleeve 35. The support sleeve 32 can support and fix the threaded sleeve 35. The threaded connection between the threaded sleeve 35 and the fixing knob 33 allows the fixing knob 33 to move up and down when rotated in different directions.

[0021] As one implementation method in this embodiment, please refer to Figure 4 - Figure 5 As shown, the docking assembly 4 includes docking shafts 41, each docking shaft 41 being located outside and movably connected to an adjusting assembly 3. The docking shafts 41 facilitate connection to the tractor's tie rod.

[0022] As one implementation method in this embodiment, please refer to Figure 4 - Figure 5 As shown, each adjusting component 3 has a support rod 36 fixedly connected to its outer side via two support plates 34. Each docking component 4 has a fixing seat 42 fixedly installed on one side. Each fixing seat 42 is located outside a support rod 36 and is movably connected to the support rod 36.

[0023] Working principle: The vertical steel frame 2 and the support component 1 support and fix multiple adjustment components 3, so that the multiple adjustment components 3 can be arranged in a triangular shape on both sides of the support component 1 and the vertical steel frame 2. The support component 1 and the vertical steel frame 2 support the multiple adjustment components 3, so that the multiple adjustment components 3 can slide back and forth and up and down respectively. By rotating the fixing knob 33, the fixing knob 33 moves outward and separates from the fixing hole 13, which can facilitate the sliding of the sliding sleeve 31. By driving the sliding sleeve 31 on the periphery of the vertical steel frame 2 to slide up and down, the docking assembly 4 on the outer side of the vertical steel frame 2 can be moved up and down synchronously. By driving the adjusting assembly 3 on the periphery of the support assembly 1 to slide back and forth, the docking assembly 4 on the outer side of the support assembly 1 can be moved back and forth synchronously. The position of multiple docking assemblies 4 can be easily adjusted according to the multiple pull rods of the tractor. By rotating the fixing knob 33, the fixing knob 33 extends to the inside of the fixing hole 13, which can support and fix the sliding sleeve 31 after it has moved, and simultaneously support and fix the position of multiple docking assemblies 4. The movable connection between the fixed base 42 and the support rod 36 allows multiple docking shafts 41 to rotate synchronously, facilitating the adjustment of the angle of the docking shafts 41 according to the angle of the tractor's tie rod. After the multiple docking components 4 are moved, they can correspond to multiple tie rods of the tractor. The multiple docking components 4 can be used to easily connect with the tractor, and simultaneously facilitate the connection and fixation of the implement.
