Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hay rakes, and particularly relates to a high-stability folding hay rake. Background Art
[0002] A hay rake is a forage harvesting machine specifically used for raking the forage scattered on the ground into windrows. Its main purpose is to fully dry the forage and facilitate the collection of hay. The main working component of the drum-type hay rake is a hay rake drum that rotates around a horizontal axis. The end face of the drum forms an angle with the advancing direction of the machine, that is, the advancing angle; the angle between the rotating end face of the drum and the tooth bar is the drum angle. At present, due to the increasing mechanization in agriculture, there are more and more foldable hay rakes to ensure a larger working width during operation and passability during movement. However, in actual use, since the existing hay rakes are getting longer, when the lifting and lowering are controlled by a hydraulic cylinder, the situation of tipping up may occur. One side of the hay rake has already dropped, but the other side has not dropped yet, or even tips up upwards, which is very unstable. Therefore, it is necessary to develop a hay rake with high stability to meet the needs. Content of the Utility Model

[0019] The present utility model will be further described below in conjunction with the accompanying drawings.
[0020] As Figures 1-6 shown, a highly stable folding rake includes a main frame 1. A horizontal frame 1a is fixedly connected to the front part of the main frame 1, a vertical frame 1b and a tail frame 1c are fixedly connected to the rear part. A towing frame 2 is rotatably connected to the front end of the horizontal frame 1a. A hydraulic oil pump 3 is fixedly connected to the towing frame 2. Two cross beams 4 are rotatably connected to the vertical frame 1b. The end of the cross beam 4 is rotatably connected to a connecting bracket 5. The rear part of the connecting bracket 5 is connected to a connecting tail frame 5a, and the bottom is fixedly connected to a connecting bottom frame 5b. A rotating rod 8 is rotatably connected to the connecting bottom frame 5b. A rotating frame 14 is fixedly connected to the middle of the rotating rod 8. A drum type rake 9 is rotatably connected to the rotating rod 8. The drum type rake 9 is controlled by a hydraulic motor 13, and the hydraulic motor 13 is controlled by the hydraulic oil pump 3. Two stabilizing rods 10 are rotatably connected to the rotating rod 8. The two stabilizing rods 10 on both sides are respectively located on both sides of the rotating frame 14. The two ends of the stabilizing rod 10 are connected to an upper stabilizing rod 10a. A secondary stabilizing rod 10b is rotatably connected to the upper stabilizing rod 10a far from the rotating frame 14. The secondary stabilizing rod 10b is rotatably connected to the lower part of the frame 9a of the drum type rake 9. An iron chain 10c is connected to the upper stabilizing rod 10a close to the rotating frame 14, and the iron chain 10c is connected to the rotating frame 14.
[0021] In order to facilitate changing the rake width, a first hydraulic cylinder 16 is rotatably connected to the middle of the cross beam 4. The end of the piston rod of the first hydraulic cylinder 16 is rotatably connected to the bottom of the end of the tail frame 1c. The top of the end of the tail frame 1c is rotatably connected to a pull rod 17. The pull rod 1 is rotatably connected to the connecting tail frame 5a. The first hydraulic cylinder 16 is controlled by the hydraulic oil pump 3.
[0022] It should be noted that the pull rod is a telescopic structure and is fixed by a positioning bolt. During operation, fine adjustment can be performed through the positioning bolt to balance the cross beam.
[0023] In order to facilitate the adjustment of the width during transportation, the connecting bracket 5 is rotatably connected to the rotating rod 8 through the rotating frame 14, and the rotating rod 8 is rotatably connected to the second hydraulic cylinder 6. The end of the piston rod of the second hydraulic cylinder 6 is rotatably connected to the connecting bracket 5, and the second hydraulic cylinder 6 is controlled by the hydraulic oil pump 3.
[0024] In order to facilitate the rotation of the rotating rod 8 , the rotating rod 8 is rotatably connected to the third hydraulic cylinder 7 , the piston rod of the third hydraulic cylinder 7 is rotatably connected to the upper part of the frame 9 a , and the third hydraulic cylinder 7 is controlled by the hydraulic oil pump 3 .
[0025] In order to ensure stability when the roller grass rake 9 rotates up and down, the two ends of the rotating rod 8 are rotatably connected with a rotating connecting rod 15, and the other end of the rotating connecting rod 15 is rotatably connected to the lower part of the frame 9a of the roller grass rake 9.
[0026] In order to facilitate movement, the connecting base 5b is rotatably connected to a first universal wheel 11, and the frame 9a is rotatably connected to a second universal wheel 12.
[0027] The specific working process of the utility model is as follows:
[0028] The traction frame 2 is connected to the tractor, and the power output shaft of the tractor is connected to the power input shaft of the hydraulic oil pump 3. The hydraulic oil pump 3 controls the first hydraulic cylinder 16 to control the rotation of the cross beam 4, the second hydraulic cylinder 6 to control the horizontal rotation of the rotating rod 8, and the third hydraulic cylinder 7 to control the vertical rotation of the roller-type grass rake 9, thereby adjusting the width of the entire grass rake to better adapt to the working conditions of grass rake and transportation. When raking grass, the hydraulic oil pump 3 controls the hydraulic motor 13 to rotate, thereby driving the grass rake roller in the roller-type grass rake 9 to rotate, and realizing grass rake.
[0029] Among them, the stabilizing rod 10 can be regarded as a torsion spring. When the frame 9a is lowered, the iron chain 10c pulls the stabilizing upper rod 10a at one end, and the stabilizing upper rod 10a at the other end descends. When the roller-type grass rake 9 is lifted, it will be affected by the elasticity of the stabilizing rod 10, so that both sides of the frame 9a are upward at the same time, thereby avoiding tilting; and when lowering, because the iron chain 10c and the rotating frame 14 will resist the stabilizing upper rod 10a, the stabilizing rod 10 will accumulate force in the opposite direction. Therefore, when the frame 9a is lowered, it will also be affected by the force of the spring, thereby avoiding tilting.
