Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery and equipment technology, specifically a hay rake that is easy to adjust. Background Technology
[0002] Hay rakes are key pieces of equipment in modern agriculture for harvesting forage. Their main function is to turn over, rake, or pile up the cut surface hay (such as alfalfa and oat hay) laid in the field for drying, silage, or drying. Traditional manual hay rakeing relies on manpower or simple tools, which is inefficient and labor-intensive. With the development of mechanization, existing single-drum hay rakes can only turn over the hay in one direction when rakeing in the field, while double-drum hay rakes gather the hay from both sides to the middle. However, during the drying process, to improve the drying effect, the hay needs to be turned over to the side facing the sun. When using a double-drum hay rake to achieve specific turning in a certain direction, one side of the drum will not work, resulting in resource waste. Single-drum hay rakes cannot achieve this when the device is turned around. Therefore, there is a need to design a single-drum hay rake that is suitable for agricultural machinery and can freely adjust the rake direction to achieve multi-angle rake gathering. Utility Model Content
[0003] To address the above technical problems, this utility model provides a single-roller hay rake suitable for agricultural machinery that can freely adjust the rake direction to achieve multi-angle rake collection, thus solving the problem that existing hay rakes cannot freely adjust the angle, resulting in the inability to achieve drying in a specific direction.
[0004] To solve the above technical problems, the technical solution of this utility model is as follows: an easily adjustable hay rake, including a frame, wheels fixedly connected to both sides of the bottom of the frame via fixed shafts, a rotating shaft rotatably connected to one side of the frame, and a first hydraulic rod hinged to the upper end of the other side via a support, a first crossbar and a second crossbar fixedly connected from top to bottom to one side of the rotating shaft, the output end of the first hydraulic rod hinged to the first crossbar, a connecting frame fixedly connected to both sides of the second crossbar via connecting plates, a third crossbar fixedly connected to the upper end of the connecting frame, a vertically arranged first fixed rod fixedly connected to the middle of the first crossbar, a second hydraulic rod hinged to one side of the first fixed rod, the output end of the second hydraulic rod hinged to the connecting frame, a bogie rotatably connected to both ends of the third crossbar via an arc-shaped frame, a hay rake mechanism rotatably connected to the bottom of the bogie, a support tube fixedly connected to one side of the bogie via an extension rod, a universal wheel rotatably connected to the bottom of the support tube, a third hydraulic rod hinged to one end of the third crossbar via a second fixed rod, and the output end of the third hydraulic rod hinged to the bogie.
[0005] Furthermore, the hay-raking mechanism includes two hay-raking discs arranged opposite each other, with several holes on the hay-raking discs, and several hay-raking rods hinged between the two hay-raking discs. Several rake teeth are fixedly connected to the hay-raking rods. The hay-raking discs are driven by a hydraulic motor, which is fixedly connected to the bogie.
[0006] Furthermore, the two ends of the first crossbar are hinged to the third crossbar by turnbuckles.
[0007] Furthermore, the connecting frame includes a connecting rod and a connecting frame. The upper end of the connecting frame is fixedly connected to the third crossbar. One end of the connecting rod is fixedly connected to the connecting plate, and the other end is fixedly connected to the lower end of the connecting frame.
[0008] Furthermore, a fourth crossbar is fixedly connected to one side of the frame, and the fourth crossbar is located on the side opposite to the rotation axis.
[0009] This utility model has the following advantages compared with the prior art:
[0010] 1. This utility model features a rotating shaft rotatably connected to one side of the frame, and a first hydraulic rod connecting the frame and the first crossbar, enabling the rotating shaft to drive the entire structure to rotate. A third hydraulic rod is hinged to one side of the third crossbar via a second fixed rod, allowing the bogie to rotate and thus driving the hay-raking mechanism to rotate at multiple angles. A universal wheel is rotatably connected to the bottom of the support tube, accommodating the multi-directional rotation of the hay-raking mechanism. The combined use of the first and third hydraulic rods allows the hay rake to be freely adjusted in multiple directions, avoiding the problem of a single-roller hay rake only moving in one direction when rakes hay in a specific direction, thus enabling directional drying.
[0011] 2. This utility model, by setting a second hydraulic rod and setting a connecting plate that is hinged to both ends of the second crossbar, and a turnbuckle that is hinged to one side of the first crossbar, can raise and lower the hay rake through the second hydraulic rod, which is convenient for transportation. By setting a fourth crossbar, it can be easily installed on agricultural machinery. By opening holes in the hay rake disc, the weight of the hay rake disc can be reduced, thus reducing energy consumption. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] like Figures 1 to 4 The diagram shows an adjustable hay rake, including a frame 1. To support the frame 1's movement, wheels 20 are fixedly connected to both sides of the bottom of the frame 1 via fixed shafts. The fixed shafts are fixedly connected to the front bottom of the frame 1, and wheels 20 are rotatably connected to both ends of the fixed shafts. To enable the hay rake to rotate, a rotating shaft 4 is rotatably connected to the rear side of the frame 1. The upper and lower ends of the rotating shaft 4 are fixedly connected to the sides of the frame 1 via supports. To provide power for the rotation of the device, a first hydraulic rod 2 is hinged to the upper front end of the frame 1 via a support. A first crossbar 3 and a second crossbar 21 are fixedly connected from top to bottom to one side of the rotating shaft 4. Both the first crossbar 3 and the second crossbar 21 are square tubular. The output end of the first hydraulic rod 2 is hinged to one end of the first crossbar 3. The extension and retraction of the first hydraulic rod 2 drives the first crossbar 3 to rotate. To connect the hay rake mechanism, connecting frames 12 are fixedly connected to both sides of the second crossbar 21 via connecting plates 22. One end of each connecting plate 22 is hinged to the second crossbar 21, and the other end is connected to the connecting frame 12. One end of the first crossbar 11 is fixedly connected to the connecting frame 12. A third crossbar 11 is fixedly connected to the upper end of the connecting frame 12. In order to install the second hydraulic rod 13, a vertically set first fixed rod 17 is fixedly connected to the middle of the first crossbar 11. The second hydraulic rod 13 is hinged to one side of the first fixed rod 17. The output end of the second hydraulic rod 13 is hinged to the middle of the bottom of the connecting frame 12. In order to realize the secondary adjustment of the hay-raking mechanism, a bogie 5 is rotatably connected to both ends of the third crossbar 11 through an arc frame 10. The hay-raking mechanism is rotatably connected to the bottom of the bogie 5. In order to facilitate steering, a support tube 6 is fixedly connected to one side of the bogie 5 through an extension rod. A universal wheel 18 is rotatably connected to the bottom of the support tube 6. In order to realize the secondary adjustment of the hay-raking mechanism, a second fixed rod 16 is fixedly connected to one end of the third crossbar 11. A third hydraulic rod 15 is hinged to the output end of the second fixed rod 16. The output end of the third hydraulic rod 15 is hinged to the bogie 5. By retracting the third hydraulic rod 15, the bogie 5 is driven to rotate, thereby realizing the secondary adjustment of the hay-raking mechanism.
[0019] To ensure that the hay is evenly integrated into a single line, the hay-raking mechanism includes two opposing hay-raking discs 7. Each hay-raking disc 7 has several holes. Five hay-raking rods 8 are evenly hinged between the two hay-raking discs 7. The hay-raking rods 8 are rotatable and adjustable at both ends. Each hay-raking rod 8 is fixedly connected to several rake teeth 9. The upper end of each rake tooth 9 is square, and two strip teeth are fixedly connected to the lower end. To rotate the hay-raking disc 7, one side of the hay-raking disc 7 is driven by a hydraulic motor, which is fixedly connected to the bogie 5.
[0020] In order to adjust the tilt of the hay-raking mechanism, the two ends of the first crossbar 3 are hinged to the third crossbar 11 by turnbuckles 14.
[0021] In order to connect the frame 1 to the hay-raking mechanism, a connecting frame 12 is used. The connecting frame 12 includes a connecting rod 121 and a connecting frame 122. The upper end of the connecting frame 122 is fixedly connected to the third crossbar 11. One end of the connecting rod 121 is fixedly connected to the connecting plate 22, and the other end is fixedly connected to the lower end of the connecting frame 122.
[0022] To facilitate installation on agricultural machinery, a fourth crossbar 19 is fixedly connected to one side of the frame 1. The fourth crossbar 19 is located on the opposite side of the rotating shaft 4.
[0023] The specific working process of this utility model is as follows:
[0024] In use, first install the hay rake onto the agricultural machinery via the fourth crossbar 19 and fix it above the frame 1. When rakeing, first turn on the hydraulic motor, which drives the rake disc 7 to rotate. The rake teeth 9 on the rake rod 8 move the hay. When adjusting the direction to the right, first extend the first hydraulic rod 2. The first hydraulic rod 2 pushes the first crossbar 3 to rotate counterclockwise. At this time, the connecting frame 12 is driven to rotate through the rotating shaft 4. The connecting frame 12 drives the third crossbar 11 and the hay rake mechanism to rotate. This completes the first stage of adjustment. If a larger angle adjustment is required, extend the third hydraulic rod 15. The third hydraulic rod 15 pushes the bogie 5 to rotate. The bogie 5 drives the hay rake mechanism to rotate. At the same time, the universal wheels 18 at the bottom of the bogie 5 follow the bogie. The rotation of 5 adapts and changes direction promptly. When it is necessary to adjust the direction to the right, simply reverse the process by retracting the first hydraulic rod 2 and the third hydraulic rod 15. In actual use, the angle can be adjusted according to the specific situation, so that the direction of the hay-raking mechanism is reversed when the device rakes hay back and forth, thereby achieving specific direction of drying. By adjusting the second hydraulic rod 13, the hay-raking device can be lifted for easy movement. When it is necessary to adjust the forward tilt angle of the hay-raking mechanism, it can be achieved by adjusting the length of the turnbuckle 14. Adjusting the hay rake according to the above steps can increase the adjustment angle. The hay rake can be adjusted left and right, so that when the hay rake rakes hay back and forth, the direction of the hay rake can be adjusted to turn the hay strips to the sunny side, improving drying efficiency.
