Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a new type of hay rake with a buffer structure. Background Technology

[0002] Every year, my country's corn, wheat, and other crop-producing areas, as well as pastures, generate large quantities of forage and straw. Therefore, a significant amount of manual labor is required to clear the harvested straw and forage. Hay rakes are forage harvesting machines that gather scattered forage into hay bales. The purpose of raking is to ensure the forage is thoroughly dried and facilitates hay collection. The buffer structure of a hay rake typically includes shock-absorbing devices and shock-absorbing springs. Shock-absorbing devices help reduce vibration and noise generated during machine operation, improving operator comfort and work efficiency. Shock-absorbing springs are usually designed to absorb and mitigate the impact forces generated during operation, protecting the machine's components from damage. These buffer structures are generally adjusted and optimized according to the design and intended use of the hay rake to achieve the best shock absorption effect.

[0003] Existing hay rakes lack independent buffer devices for the rake teeth, making it impossible to completely clear straw and hay from depressions and low-lying areas. In addition, hay rakes have a wide working range, requiring a smaller footprint when not in use. Therefore, there is an urgent need to design a new type of hay rake with a buffer structure to solve these problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a novel hay rake with a buffer structure is provided. This technical solution solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel hay rake with a buffer structure includes a main beam. The right rear end of the main beam is threadedly connected to the left end of a crossbar, and the right end of the crossbar is threadedly connected to the upper end of a vertical bar. The lower end of the vertical bar is fixedly connected to the upper end of a partition plate. A circular welded component is fixedly installed at the rear end of the main beam. A turntable is rotatably connected to the bottom of the circular welded component. Several rotating rods are evenly arranged on the side of the turntable. The output end of each rotating rod is inserted into one end of a connecting rod. Several rake teeth are sleeved on the other end of the connecting rod. The upper end of each rake tooth extends beyond the top of the connecting rod and is fixedly connected to a fixing block. A compression spring is fixedly connected between the fixing block and the connecting rod, and the compression spring is sleeved on the surface of the rake teeth.

[0007] Furthermore, a damping spring is fixedly connected to the bottom of the turntable, the lower end of the damping spring is fixedly installed on the upper end of the support rod, a fixing rod is sleeved on the surface of the damping spring, the lower end of the fixing rod is fixedly installed on the upper end of the rotating shaft, and wheels are rotatably connected to both ends of the rotating shaft.

[0008] Furthermore, there are six rotating rods and six connecting rods, and the rotating rods and connecting rods are movably connected by pins and latches, and each connecting rod is fixedly connected with four rake teeth.

[0009] Furthermore, the maximum height that the fixing block can reach is less than the lower end height of the main beam.

[0010] Furthermore, the length of the crossbar is greater than the length from the right end of the connecting rod to the right end of the main beam.

[0011] Furthermore, the height of the partition is adapted to the height of the rake teeth, and the partition is located on the right front of the disc weldment.

[0012] As a preferred technical solution of this utility model, compared with the prior art, this utility model provides a novel hay rake with a buffer structure, which has the following beneficial effects:

[0013] In this invention, by connecting the rake teeth to the rotating rod via a pin and a latch, the rake assembly can be easily disassembled for maintenance and replacement, and the floor space occupied by the rake when not in operation is reduced. The vertical rod fixed to the upper end of the partition is threaded to one end of the horizontal rod, and the left end of the horizontal rod is threaded to the main beam, facilitating the removal of the partition and the horizontal rod, further reducing space requirements. During operation, when the rake teeth encounter pits or raised areas, the compression spring causes them to rise or fall, providing cushioning and reducing damage to the rake teeth, while also facilitating deeper weed removal. After the connecting rod rotates past the main beam, the rotating rod controls its rotation, causing the rake teeth to rotate upwards. After the connecting rod rotates past the end away from the main beam, the rotating rod again controls its rotation, restoring the rake teeth to a perpendicular position to the ground, thus completing the cyclical operation.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-3 As shown, a novel hay rake with a buffer structure includes a main beam 1. The right rear end of the main beam 1 is threadedly connected to the left end of a crossbar 2. The right end of the crossbar 2 is threadedly connected to the upper end of a vertical rod 3. The lower end of the vertical rod 3 is fixedly connected to the upper end of a partition plate 4. The threaded connection structure facilitates the removal and replacement of the partition plate 4, and reduces space occupation. A circular welded component 5 is fixedly installed at the rear end of the main beam 1. A turntable 6 is rotatably connected to the bottom of the circular welded component 5. Several rotating rods 7 are evenly arranged on the side of the turntable 6. The output end of the rotating rod 7 is inserted into one end of a connecting rod 8. The rotating rod 7 and the connecting rod 8 are movably connected, which facilitates the disassembly and assembly of the hay-raking assembly and reduces space occupation. The other end of the connecting rod 8 is fitted with several rake teeth 9. The upper end of the rake teeth 9 extends out of the top of the connecting rod 8 and is fixedly connected to the fixing block 11. A compression spring 10 is fixedly connected between the fixing block 11 and the connecting rod 8. The compression spring 10 is sleeved on the surface of the rake teeth 9. Through the compression spring 10, the rake teeth 9 are made to rise or fall when passing through uneven places, which provides cushioning and reduces damage to the rake teeth 9 during operation, and can also clean the hay more deeply.

[0021] In another embodiment provided by this utility model, such as Figure 2 As shown, a damping spring 16 is fixedly connected to the bottom of the turntable 6. The lower end of the damping spring 16 is fixedly installed on the upper end of the support rod 14. A fixing rod 15 is sleeved on the surface of the damping spring 16. The lower end of the fixing rod 15 is fixedly installed on the upper end of the rotating shaft 13. Wheels 12 are rotatably connected to both ends of the rotating shaft 13. Through the damping spring 16 and the fixing rod 15, the wheels 12 move forward more smoothly, reducing the vibration of the hay rake and making the hay rake work more stably and efficiently.

[0022] In another embodiment provided by this utility model, such as Figure 3As shown, there are six rotating rods 7 and six connecting rods 8. The rotating rods 7 and the connecting rods 8 are movably connected by pins 17 and latches 18. Each connecting rod 8 is fixedly connected with four rake teeth 9. The rotating rods 7 and the connecting rods 8 are inserted and fixed by pins 17 and latches 18, which provides a certain degree of firmness while facilitating the disassembly, maintenance and replacement of the connecting rods 8.

[0023] In another embodiment provided by this utility model, such as Figure 1 As shown, the maximum height that the fixed block 11 can reach is less than the lower end height of the main beam 1. The fixed block 11 is fixedly connected to the upper end of the rake tooth 9, and the rake tooth 9 is connected to the connecting rod 8 through the compression spring 10 to form a buffer structure. However, since the turntable 6 controls the rotation of the rotating rod 7 and the connecting rod 8, the height of the fixed block 11 is less than the height of the main beam 1 to avoid collisions during operation.

[0024] In another embodiment provided by this utility model, such as Figure 1 As shown, the length of the crossbar 2 is greater than the length from the right end of the connecting rod 8 to the right end of the main beam 1, to avoid collision between the connecting rod 8 and the partition 4.

[0025] In another embodiment provided by this utility model, such as Figure 1 As shown, the height of the partition 4 is matched with the height of the rake teeth 9, and the partition 4 is located on the right side of the turntable 6. The fact that the height of the partition 4 and the rake teeth 9 are the same can better restrict the movement of the forage.

[0026] Basic Principle: In this utility model, the connecting rod 8 is movably installed at one end of the rotating rod 7 via the pin 17 and the latch 18. Then, the vertical rod 3 is threadedly connected to the right end of the horizontal rod 2. When the hay rake is started, the turntable 6 rotates counterclockwise, which in turn causes the rake teeth 9 to rotate through the rotating rod 7 and the connecting rod 8. The hay rake moves along the main beam 1 and sweeps the hay to one side of the partition 4 through the rake teeth 9. The partition 4 blocks the swept hay. During the operation of the rake teeth 9, when encountering pits and raised areas, the compression spring 10 acts as a buffer, and the rising or falling of the rake teeth 9 clears the weeds. After the connecting rod 8 rotates past the main beam 1, the rotating rod 7 controls the connecting rod 8 to rotate, which in turn rotates the rake teeth 9 upward. After the connecting rod 8 rotates past the end away from the main beam 1, the rotating rod 7 controls the connecting rod 8 to rotate again, which restores the rake teeth 9 to a state perpendicular to the ground, thus completing the cycle.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
