[0028] Further, the number of connecting sliding blocks 3110 is two, and the connecting sliding blocks 3110 are symmetrically distributed on the outer wall of the pick hanging arm 3111, so that the outer wall of the pick hanging arm 3111 can be uniformly supported on both sides, thereby improving the installation support stability of the pick hanging arm 3111.

[0029] Further, the outer wall of the connecting sliding block 3110 is adapted to the inner wall of the adjusting sliding slot 311, and the outer wall of the connecting sliding block 3110 is provided with a clamping hole, so that the close fit between the connecting sliding block 3110 and the adjusting sliding slot 311 can be ensured, thereby improving the installation stability.

[0030] Further, the outer wall of the connecting sliding block 3110 is adapted to the inner wall of the adjusting sliding slot 311, and the outer wall of the connecting sliding block 3110 is provided with a clamping hole, so that the close fit between the connecting sliding block 3110 and the adjusting sliding slot 311 can be ensured, thereby improving the installation stability.

[0031] The auxiliary support mechanism 32 includes a sliding sleeve 321 fixedly connected to the outer wall of the pick hanging arm 3111, a sliding rod 322 slidably arranged in the inner wall of the sliding sleeve 321, a clamping rod 325 fixedly connected to the outer wall of the sliding sleeve 321, a pull plate 326 fixedly connected to the end of the clamping rod 325 away from the outer wall of the sliding sleeve 321, a second spring 327 fixedly connected to the outer wall of the pull plate 326 away from the sliding sleeve 321, a positioning hole 323 formed in the outer wall of the sliding rod 322, and a roller 324 fixedly connected to the bottom end of the sliding rod 322.

[0032] Further, the positioning hole 323 is two in number and is symmetrically arranged on the outer wall of the sliding rod 322, and the up and down positioning holes 323 can control the up and down extension positioning of the sliding rod 322.

[0033] Further, the outer wall of the clamping rod 325 is matched with the inner wall of the positioning hole 323, and the outer wall of the sliding rod 322 is matched with the inner wall of the sliding sleeve 321, so as to ensure the support stability during the clamping of the clamping rod 325, and the support stability between the sliding rod 322 and the sliding sleeve 321.

[0034] The implementation principle of the agricultural machine quick picking and hanging traction device of the embodiment is as follows: the hanging ring 3113 arranged at one end of the picking and hanging arm 3111 can be hooked and connected with the hook at one end of the agricultural machine, the fixed seat 1 is fixedly installed on the tractor through the fixing plate 2, then when the picking and hanging arm 3111 is installed, first, the connecting sliding block 3110 on the outer wall of one end is aligned, then the tractor is moved backward by the operator to drive the fixed seat 1 to move, then the connecting sliding block 3110 is inserted into the adjusting sliding groove 311 on the outer wall, and the position of the connecting sliding block 3110 inserted into the adjusting sliding groove 311 is different when the agricultural machine is at different heights, so as to cooperate and connect the agricultural machines at different heights. The positioning column 313 will be moved during the movement of the fixed seat 1, at this time, the stress slope 314 formed on the outer wall of the positioning column 313 will be in contact with and subjected to the extrusion action of the outer wall of the connecting sliding block 3110, and then it will be shortened inward, and at the same time, the first spring 312 will be extruded and compressed during the shortening process, until the clamping hole formed on the outer wall of the connecting sliding block 3110 is moved to the position of the positioning column 313, so that the first spring 312 will be reset to push the outer wall of the positioning column 313 to be clamped in the clamping hole, so as to complete the fixed and limited installation of the connecting sliding block 3110. In this way, the tractor and the agricultural machine can be connected and fixed, and when the connection is released, only the hydraulic push rod 318 needs to be started to make the output end shortened, so as to drive the first fixed rod 316 and the second fixed rod 317 to move to the right side, so as to drive the left and right connecting rods 315 to move to the right side, and then drive the positioning column 313 to be shortened again, so that the outer wall of the positioning column 313 is separated from the inner wall of the clamping hole formed on the outer wall of the connecting sliding block 3110, so as to release the positioning and clamping. This connection method is more convenient, and one person can complete the disassembly and assembly, thereby saving time and improving the agricultural efficiency. The hanging ring 3113 can be rotated at a certain angle through the connecting bearing 3112, so as to adapt to the small amplitude swing of the agricultural machine during traction, and reduce the stress concentration of the connection part.

[0035] When the traction agricultural machinery is heavy, the left and right pull plates 326 can be pulled to move the clamping rods 325 to the left and right directions, and the second springs 327 will be stretched during the movement of the pull plates 326. At this time, the outer wall of the clamping rod 325 will be separated from the inner wall of the positioning hole 323, so that the sliding rod 322 will be separated from the limit and move downward in the inner wall of the sliding sleeve 321. Thus, the sliding rod 322 will drive the bottom roller 324 to move downward until it contacts the ground, thereby supporting the tractor and the agricultural machinery connected part. At this time, the upper positioning hole 323 will move to the position of the clamping rod 325, so that the pull plate 326 can be loosened. Through the rebound action of the second spring 327, the outer wall of the clamping rod 325 can be clamped in the inner wall, completing the positioning of the sliding rod 322. Thus, a part of the vertical load can be shared, and the traction stability can be improved.
