DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] See also Figure 1 and Figure 2 The utility model provides a quick-release suspension assembly for agricultural machinery, which includes a driving member 1, which is rotatably connected to the rear end of the agricultural machinery. The driving force of the driving member 1 is controlled by the engine or motor of the agricultural machinery to drive the driving member 1 to rotate. The side wall of the driving member 1 is provided with a connecting arm 2; a suspension beam 5, which is rotatably connected to the rear end of the agricultural machinery, and the suspension beam 5 and the connecting arm 2 are connected through an intermediate connecting rod 3 to ensure that when the driving member 1 rotates, the transmission force is transmitted to one end of the intermediate connecting rod 3, which is rotatably connected to the connecting arm 2, and the other end is rotatably connected to the suspension beam 5. The driving member 1 rotates to drive the suspension beam 5 to rotate, thereby adjusting the position of the suspension beam 5; a detachable connecting plug-in 6, which is used to connect the intermediate connecting rod 3 with the suspension beam 5 and the connecting arm 2, to ensure that when the agricultural machinery suspension needs to be disassembled, the suspension can be disassembled more quickly by disassembling the plug-in 6.

[0020] See also Figure 3 and Figure 4Preferably, the connector 6 of the utility model includes a force-bearing pin 63 and a force-bearing plate 62 fixed to one end of the force-bearing pin 63, and the end of the force-bearing plate 62 away from the force-bearing pin 63 is provided with a socket 61, and the socket 61 is rotated to a suitable position by rotating the force-bearing plate 62, and then the position of the force-bearing plate 62 is fixed by the fixing bolt 7, thereby limiting the rotation of the force-bearing pin 63, facilitating the subsequent disassembly of the force-bearing pin 63, and thus quickly disassembling the suspension, and the two sides of the end of the connecting arm 2 away from the driving member 1 are provided with connecting parts, The connecting part is provided with a pin hole 43, and the outer wall of the connecting part is provided with a positioning hole 44 which is arranged in cooperation with the insertion hole 61. The insertion hole 61 and the positioning hole 44 cooperate with each other to ensure that the fixing bolt 7 can adjust the position of the force-bearing plate 62. One end of the intermediate connecting rod 3 is provided with a first connecting head 8 which cooperates with the connecting part. The force-bearing pin 63 is passed through the pin hole 43 and the first connecting head 8. The position of the first connecting head 8 and the connecting arm 2 is fixed by the force-bearing pin 63, thereby ensuring the rotational connection relationship between the first connecting head 8 and the connecting arm 2.

[0021] In addition, a through hole is provided on the suspension beam 5 of the utility model, and a second connecting head 4 is provided on the other end of the intermediate connecting rod 3. The suspension beam 5 is inserted into the inside of the second connecting head 4 and a pin hole 43 and a positioning hole 44 are provided on the second connecting head 4. The force-bearing pin 63 is passed through the pin hole 43 and the through hole to ensure the connection relationship between the second connecting head 4 and the suspension beam 5.

[0022] See also Figure 3 and Figure 4 Furthermore, when the force-bearing pin 63 of the utility model is inserted into the interior of the pin hole 43, the force-bearing plate 62 is rotated to a certain position. At this time, the insertion hole 61 corresponds to the position of the positioning hole 44, and the fixing bolt 7 is tightened into the interior of the insertion hole 61 and the positioning hole 44, so as to fix the position of the force-bearing plate 62 to prevent the force-bearing pin 63 from rotating or the axis from moving during use, causing the connecting head to fall off and affecting the normal connection relationship. The end of the force-bearing pin 63 away from the force-bearing plate 62 is provided with a threaded portion, and the interior of the pin hole 43 is provided with an internal thread that cooperates with the threaded portion. By rotating the force-bearing plate 62, the force-bearing pin 63 is screwed onto the internal thread, thereby ensuring the reliability of the connection of the force-bearing pin 63 and preventing the connecting pin from rotating and moving.

[0023] In this embodiment, combined with Figure 1 to Figure 4When in use, the first connector 8 is aligned with the pin hole 43 of the connecting arm 2 or the second connector 4 is aligned with the pin hole 43 of the suspension beam 5, and then the force pin 63 is inserted into the pin hole 43 and the through hole, and then the force plate 62 is rotated by manpower to tighten the force pin 63 to the corresponding internal thread, and then the socket 61 of the force plate 62 is overlapped with the positioning hole 44, and the fixing bolt 7 is tightened to the inside of the socket 61 to complete the fixation of the position of the force plate 62. At this time, the position of the force pin 63 is fixed. When disassembling, it is only necessary to remove the fixing bolt 7, and then rotate the force plate 62 in the opposite direction to complete the disassembly of the connector. In order to ensure that the intermediate connecting rod is better disassembled, the first connector 8 and the second connector 4 can be set to a detachable structure, by setting threaded holes at both ends of the intermediate connecting rod, and then setting an externally threaded docking portion 41 at the tail of the first connector 8 and the second connector 4, to ensure that the connector is screwed to the inside of the threaded hole, and then a hexagonal nut 42 is set on the outside of the docking portion 41 to ensure better rotation of the connector.

[0024] In summary, the utility model provides a quick-release suspension assembly for agricultural machinery, including: a driving member, which is rotatably connected to the rear end of the agricultural machinery, the driving force of the driving member is controlled by the engine or motor of the agricultural machinery, and drives the driving member to rotate, and the side wall of the driving member is provided with a connecting arm; a suspension beam, which is rotatably connected to the rear end of the agricultural machinery, and the suspension beam and the connecting arm are connected by an intermediate connecting rod, so as to ensure that when the driving member rotates, the transmission force is transmitted to one end of the intermediate connecting rod, which is rotatably connected to the connecting arm, and the other end is rotatably connected to the suspension beam, and the driving member rotates to drive the suspension beam to rotate, thereby adjusting the position of the suspension beam; a detachable connecting plug-in member, which is used to connect the intermediate connecting rod with the suspension beam and the connecting arm, so as to ensure that when the agricultural machinery suspension needs to be disassembled, the suspension can be disassembled more quickly by disassembling the plug-in member. In summary, the technical effect produced by the utility model is that by setting a latch-type fixing structure, it is ensured that when the suspension needs to be disassembled, the suspension can be disassembled by disassembling the latch structure, thereby ensuring that the suspension can be disassembled quickly.
