Problems solved by technology

[0008] 2. Due to the multiple rotating rods and spring connecting rods arranged along the circumference of the rotor device, the installation angles of the raking springs on each spring connecting rod are different. From the starting raking position to the raking end position, the raking spring The angle is to gradually change from inclination to vertical to carry out the operation of raking grass, and then gradually change from vertical to inclination to perform the operation of putting down the grass; The root rotating rod cannot be interchanged and used universally, which is inconvenient to install

Embodiment 1

[0035] The rotary rake rake spring connecting rod stabilizes the connection mechanism. The rubber pad 3 is sleeved on the end of the spring connecting rod 2, and then a section of the end of the spring connecting rod 2 is inserted into the rotating rod 1, and then the flange plate 2 The three cylindrical holes 20-1 on the 20 are respectively aligned with the cylindrical holes 10-1 on the flange 10, and then the bolt 4 passes through the flange 2 20, the rubber pad 3 and the flange 10 in sequence , and then be fastened by nut 5, so that spring connecting rod 2 is subjected to centrifugal force and the weeds on the ground when the weeds on the ground are held by the live grass roots, grass stems, grass vines, etc. Make the spring connecting rod 2 and the rotating rod 1 have mechanical collision and mechanical friction when they work at high speed, so as to avoid the generated noise.

Embodiment 2

[0037] The rotary hay rake rake spring connecting rod stabilizes the connection mechanism. The rubber pad 3 is sleeved on the end of the spring connecting rod 2, and then a section of the end of the spring connecting rod 2 is inserted into the rotating rod 1 to adjust the angular position, and then Tighten the external hexagonal internal thread sleeve 1-2 forward, so that the external hexagonal internal thread sleeve 1-2 squeezes the external thread 1-1 with a plurality of wedge-shaped Cao, so that the external thread 1-1 section on the rotating rod 1 The inner wall of the inner wall firmly holds the part of the spring connecting rod 2 inserted into the rotating rod 1, and then connects the three cylindrical holes 4 2-10 on the flange 4 2-1 with the cylindrical holes on the flange 3 1-20 respectively Three 1-200 alignment, and then the bolt 4 passes through the flange four 2-1, rubber pad 3 and flange three 1-20 in turn, and then tightened by the nut 5, avoiding the welding of ...

Abstract

The invention discloses a raking spring connecting rod stable connecting mechanism of a rotary hay rake. The raking spring connecting rod stable connecting mechanism comprises rotating rods and springconnecting rods, a first flange plate is arranged at the end of each rotating rod, a plurality of first cylindrical holes are evenly formed in the circumference of each first flange plate, a second flange plate is arranged at the end of each spring connecting rod, and a plurality of second cylindrical holes are evenly formed in the circumference of each second flange plate; a rubber pad is arranged between each first flange plate and the corresponding second flange plate, one section of the end of each spring connecting rod is inserted into the corresponding rotating rod, a bolt sequentiallypenetrates through each second flange plate, the corresponding rubber pad and the corresponding first flange plate and then is fastened by a nut, mechanical collision and mechanical friction between the spring connecting rods and the rotating rods during high-speed work are avoided, and generated noise is avoided; and the situation that the welding angles of lock catches and the rotating rods aredifferent is avoided, the spring connecting rods are convenient to install, and all the rotating rods can be exchanged and used universally.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery. Specifically, the invention relates to a stable connection mechanism of a raking spring connecting rod of a rotary rake rake. Background technique [0002] The structure of the current rotary hay rake is as follows: figure 1 As shown, the cylindrical cam in the rotor device drives a plurality of rotating shafts to swing, and the rotating shaft swings with the rotating rod, and the rotating rod carries the spring connecting rod with the raking spring to realize the raking operation. [0003] There are two main ways to install the spring connecting rod and the rotating rod: [0004] The first type: if figure 2 As shown, there is a lock buckle on one side of the rotating rod, and a locking piece on one side of the spring connecting rod. A section of the end of the spring connecting rod is inserted into the rotating rod, and at the same time, the locking piece is inserted into the l...
