Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to an adjustable rotating hay rake. Background Technology

[0002] After harvesting, hay is dried in the field. During this process, the hay needs to be spread out to promote the evaporation of moisture. After drying, a hay rake is used to gather the hay into strips, which are then easily baled using a hay baler. Currently, most hay rakes have a fixed rake height, but the thickness of the hay varies during drying. This makes them unsuitable for hay of different thicknesses, leading to missed hay, poor rake efficiency, and other limitations. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable rotating hay rake to solve the problems mentioned in the background art and facilitate its widespread application.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] An adjustable rotating hay rake includes a cover. Two fixing blocks, a first fixing block and a second fixing block, are symmetrically connected to the bottom of the cover. A drive motor is fixedly connected to one side of the outer wall of the first fixing block. The output end of the first drive motor passes through the first fixing block and is fixedly connected to a bidirectional screw. The end of the bidirectional screw away from the first fixing block is rotatably connected to the inner wall of the second fixing block. Threaded blocks are threaded to both sides of the bidirectional screw. A hinge seat is fixedly connected to the bottom of the threaded blocks. A lifting rod is movably connected to the first hinge seat. A second hinge seat is movably connected to the end of the lifting rod away from the first hinge seat. A movable block is fixedly connected to the bottom of the second hinge seat. A fixed rod is slidably sleeved inside the movable block. A first upright plate and a second upright plate are fixedly connected to both sides of the fixed rod. A support plate is fixedly connected to the bottom of the first and second upright plates. A drive motor is fixedly connected to both sides of the bottom of the support plate. A fixed disk is fixedly connected to the output end of the second drive motor. Evenly distributed mounting rods are fixedly connected to the outer periphery of the fixed disk. Evenly distributed spring teeth are fixedly connected to the bottom of the mounting rods.

[0006] Furthermore, the two lifting rods are arranged in a cross configuration, and the two lifting rods are hinged at the intersection.

[0007] Furthermore, symmetrical grooves are provided on both sides of the inner wall of the machine cover, and a slider is slidably connected in the groove. The end of the slider away from the groove is fixedly connected to the outer wall of the support plate.

[0008] Furthermore, rollers are rotatably connected to both sides of the machine cover, and a push handle is fixedly connected to the front of the machine cover.

[0009] Furthermore, the threads on both sides of the bidirectional screw rotate in opposite directions.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model discloses an adjustable rotary hay rake. Starting the second drive motor causes the fixed disc to rotate, which in turn causes the spring teeth to rotate, enabling hay rake operations on the dried hay. Starting the first drive motor causes the bidirectional screw to rotate, which in turn causes the threaded blocks to move relative to or towards each other, thereby raising or lowering the two lifting rods and adjusting the height of the support plate. This allows the spring teeth to rake and gather hay of different thicknesses, improving the hay rake effect. Attached Figure Description

[0020] Depend on Figures 1 to 4 As shown, an adjustable rotating hay rake includes a cover 1. Two fixing blocks 2 and 3 are symmetrically connected to the bottom of the cover 1. A drive motor 4 is fixedly connected to one side of the outer wall of the fixing block 2. The output end of the drive motor 4 passes through the fixing block 2 and is fixedly connected to a bidirectional screw 5. The end of the bidirectional screw 5 away from the fixing block 2 is rotatably connected to the inner wall of the fixing block 3. Threaded blocks 6 are threaded to both sides of the bidirectional screw 5. A hinge seat 7 is fixedly connected to the bottom of the threaded block 6. A lifting rod 8 is movably connected to the hinge seat 7. The end of the lifting rod 8 away from the hinge seat 7 is movable. A hinge seat 2 9 is connected, and a movable block 10 is fixedly connected to the bottom of the hinge seat 2 9. A fixed rod 11 is slidably sleeved inside the movable block 10. A first upright plate 12 and a second upright plate 13 are fixedly connected to both sides of the fixed rod 11. A support plate 14 is fixedly connected to the bottom of the first upright plate 12 and the second upright plate 13. When the drive motor 1 4 is started, it drives the bidirectional screw 5 to rotate, which in turn drives the threaded block 6 to move relative to or towards each other, which in turn drives the two lifting rods 8 to rise or fall, thereby adjusting the height of the support plate 14. This allows the spring teeth 18 to gather and collect spread hay of different thicknesses, improving the hay gathering effect.

[0021] A second drive motor 15 is fixedly connected to both sides of the bottom of the support plate 14. A fixed plate 16 is fixedly connected to the output end of the second drive motor 15. A uniformly distributed mounting rod 17 is fixedly connected to the outer periphery of the fixed plate 16. A uniformly distributed spring tooth 18 is fixedly connected to the bottom of the mounting rod 17. When the second drive motor 15 is started, the fixed plate 16 is driven to rotate. The rotation of the fixed plate 16 drives the spring tooth 18 to rotate, which enables the raking of the dried hay.

[0022] The two lifting rods 8 are arranged in a cross configuration, and the intersection of the two lifting rods 8 is hinged to achieve the adjustment of the angle of the two lifting rods 8.

[0023] The inner wall of the cover 1 has symmetrical grooves 19 on both sides. A slider 20 is slidably connected in the groove 19. The end of the slider 20 away from the groove 19 is fixedly connected to the outer wall of the support plate 14. The interaction between the groove 19 and the slider 20 ensures the stability of the support plate 14 when it moves.

[0024] Rollers 21 are rotatably connected to both sides of the cover 1, and a push handle 22 is fixedly connected to the front of the cover 1. By setting the rollers 21 and the push handle 22, it is convenient to move the device.

[0025] The threads on both sides of the bidirectional screw 5 have opposite directions, enabling the threaded blocks 6 to move simultaneously or relative to each other.

[0026] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
