Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and in particular relates to a sickle connector device. Background Technology

[0002] Connectors are mechanical components used to connect two or more parts. They are commonly found in tools, machinery, and electronic equipment to achieve structural fixation, force transmission, or functional coordination. They come in various forms, such as buckles, bolts, pins, and adapters. They are mostly made of metal or high-strength plastic, possessing good stability and durability. In agricultural implements, connectors are used to connect the sickle body and the handle. Typically, the base of the sickle blade has a perforated metal lug, and the top of the handle has a metal sleeve or tenon. The lug and the part connecting to the handle pass through the connector and are secured by a nut or a buckle, forming a stable angle between the blade and the handle. This structure ensures effective force transmission during mowing, prevents loosening or detachment, and guarantees safety and efficiency.

[0003] When connecting the connector to the sickle body, bolts are required for fixation to ensure structural stability and safety. However, current connector bolt holes lack necessary anti-loosening designs. In actual use, continuous vibration and impact during mowing or harvesting can cause slight rotation or displacement of the connector, leading to gradual loosening of the bolts. If not detected and tightened in time, the bolts may come off completely, ultimately causing the connection between the sickle body and handle to fail, or even the blade to fall off. This not only affects work efficiency but may also cause safety accidents, seriously threatening the personal safety of users. Therefore, the lack of anti-loosening design in the bolt holes significantly reduces the reliability and functionality of the connector. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1-5 This utility model is a sickle connecting device, including a handle mounting component 1, a blade mounting component 2, an assembly hole 3, a bolt body 4, and a nut body 5. The handle mounting component 1 includes a fifth enclosing piece 1.1 and a clamping piece 1.2. The fourth enclosing piece 1.1 is circumferentially arranged to form a handle receiving space with an assembly opening 1.3, which is opposite to the insertion opening 2.4. The blade mounting component 2 includes a first enclosing piece 2.1, a second enclosing piece 2.2, and a third enclosing piece 2.3. The first enclosing piece 2.1 and the second enclosing piece 2.2 are arranged at intervals to form a blade receiving space with an insertion opening 2.4. The third enclosing piece 2.3 is also provided on opposite sides of the first enclosing piece 2.1, protruding towards the second enclosing piece 2.2. One end of the handle mounting component 1 is fixedly connected to the blade mounting component 2. The handle of the sickle is placed inside the handle mounting component 1, and the sickle body is placed inside the blade mounting component 2. Four mounting holes 3 are symmetrically opened on the blade mounting component 2. Bolt bodies 4 are inserted through the mounting holes 3. Nut bodies 5 are threadedly connected to the bolt bodies 4. Spring plate mounting grooves 6 are opened on the mounting holes 3 and communicate with the outer surface of the blade mounting component 2. Metal spring plates 7 are fixedly connected to the inner wall of the spring plate mounting grooves 6.

[0022] By adopting the above technical solution, the sickle body is sent into the inside of the blade mounting part, the bolt body passes through the inside of the assembly hole, and the metal spring in the spring mounting groove squeezes the head of the bolt body and the nut body, generating a radial clamping force with the bolt body shank to prevent the bolt body from easily loosening.

[0023] Four adjusting blocks 8 are symmetrically fixedly connected to the cutter head mounting part 2, which are connected to the spring plate mounting slot 6. The adjusting blocks 8 have adjusting holes 9 inside, and the adjusting holes 9 are in the shape of a frustum.

[0024] By adopting the above technical solution, when the bolt body and nut body enter the interior of the adjusting block, the inclined surface of the adjusting hole forces the head of the bolt body and the nut body to move towards the center, which facilitates the quick centering and positioning of the bolt body.

[0025] A compensation mounting shell 10 is symmetrically fixedly connected to the tool holder mounting part 1. The interior of the compensation mounting shell 10 is connected to the interior of the tool holder mounting part 1. A rubber compensation block 11 is slidably connected inside the compensation mounting shell 10.

[0026] By adopting the above technical solution, the sickle handle enters the inside of the handle mounting component, the rubber compensation block moves out of the compensation mounting shell, and together with other bolts, the sickle handle is firmly fixed. When facing a sickle handle with a diameter smaller than the internal diameter of the handle mounting component, the compensation mounting shell facilitates the fixing of the small-diameter handle through physical compensation.

[0027] A reinforcing block 12 is symmetrically fixedly connected to the rubber compensation block 11. The surface hardness of the reinforcing block 12 is higher than that of the rubber compensation block 11.

[0028] By adopting the above technical solution, the reinforcing block can increase the contact area and improve the friction. When the sickle handle is squeezed, the reinforcing block contacts the handle surface first and will not be easily deformed by pressure. The guide block deforms, which makes it convenient to wrap sickle handles of different diameters.

[0029] The rubber compensation block 11 has guide blocks 13 fixedly connected to both sides and slidably connected to the compensation mounting shell 10. The guide blocks 13 are designed as isosceles trapezoids.

[0030] By adopting the above technical solution, when the rubber compensation block slides along the inside of the compensation mounting shell, the guide block slides along the inner wall of the compensation mounting shell, and the isosceles trapezoid has a self-locking effect.

[0031] A threaded rod 14 is rotatably connected to the compensation mounting shell 10. One end of the threaded rod 14 passes through the interior of the compensation mounting shell 10 and is meshed with the interior of the rubber compensation block 11. A connecting rod 15 is rotatably connected to both the upper and lower surfaces of the tool holder mounting part 1. One end of the connecting rod 15 is meshed with the other end of the threaded rod 14 through a bevel gear.

[0032] By adopting the above technical solution, the connecting rod is rotated, and the bevel gear at one end of the connecting rod contacts and meshes with the bevel gear at the other end of the threaded rod. Then, by switching the rotation direction of the connecting rod, the rubber compensation block is controlled to move out or retract into the compensation mounting housing.

[0033] A synchronous drive rod 16 is rotatably connected to one side of the tool holder mounting part 1. The surface of the synchronous drive rod 16 is connected to the other end of the connecting rod 15 through bevel gear meshing. Rotary drive blocks 17 are fixedly connected to both the top and bottom ends of the synchronous drive rod 16.

[0034] By adopting the above technical solution, rotating the rotary drive block controls the synchronous drive rod to rotate on one side of the tool holder mounting part. The bevel gear on the surface of the synchronous drive rod contacts and meshes with the bevel gear at the other end of the connecting rod, providing drive for the rotation of the connecting rod.

[0035] The bevel gears on the surfaces of the two synchronous drive rods 16 rotate in the same direction.

[0036] By adopting the above technical solution, the rotation direction of the bevel gear makes the rotation direction of the two connecting rods the same.

[0037] A specific application of this embodiment is as follows: the sickle body is sent into the inside of the blade mounting part 2, the bolt body 4 passes through the inside of the assembly hole 3, and the metal spring 7 inside the spring mounting groove 6 squeezes the head of the bolt body 4 and the nut body 5, generating a radial clamping force with the bolt body 4 shaft to prevent the bolt body 4 from easily loosening. When the bolt body 4 and the nut body 5 enter the inside of the adjusting block 8, the inclined surface of the adjusting hole 9 forces the head of the bolt body 4 and the nut body 5 to move towards the middle, making it convenient to quickly center and position the bolt body 4.

[0038] A specific application of this embodiment is as follows: The sickle handle enters the handle mounting component 1. The connecting rod 15 is rotated, causing a bevel gear at one end of the connecting rod 15 to contact and mesh with a bevel gear at the other end of the threaded rod 14. Then, by switching the rotation direction of the connecting rod 15, the rubber compensation block 11 is controlled to move out of or into the compensation mounting shell 10. The rotation drive block 17 is rotated, controlling the synchronous drive rod 16 to rotate on one side of the handle mounting component 1. The bevel gear on the surface of the synchronous drive rod 16 contacts and meshes with the bevel gear at the other end of the connecting rod 15, providing drive for the rotation of the connecting rod 15. The rotation direction of the bevel gears ensures that the rotation directions of the two connecting rods 15 are the same. The rubber compensation block... 11. Remove the compensating mounting shell 10 from the interior and, together with other bolts, securely fix the sickle handle. For sickle handles with a diameter smaller than the internal diameter of the handle mounting piece 1, the compensating mounting shell 10 provides physical compensation to facilitate the fixing of small-diameter handles. The reinforcing block 12 increases the contact area and improves friction. When the sickle handle is squeezed, the reinforcing block 12 contacts the handle surface first and will not be easily deformed by pressure. The guide block 13 deforms to facilitate wrapping sickle handles of different diameters. When the rubber compensating block 11 slides along the interior of the compensating mounting shell 10, the guide block 13 slides along the inner wall of the compensating mounting shell 10. The isosceles trapezoid has a self-locking effect.
