Abstract
Description
Technical Field
[0001] This utility model relates to a large agricultural machinery implement mounting device, belonging to the field of agricultural machinery equipment technology. Background Technology
[0002] Agricultural machinery implement mounting devices are devices installed on agricultural machinery for mounting and securing various agricultural implements (such as cart wheels). The main function of these devices is to improve agricultural production efficiency and facilitate the transportation of crops, implements, and other items by farmers in the fields.
[0003] Agricultural machinery often needs to be used with implements such as trailers to carry more loads. The machinery and trailers are connected via a trailer hitch. Traditional trailer hitchs typically consist of a tow lug at the rear of the machinery, a longitudinal connecting beam at the front of the trailer with a connecting lug, and a pin to secure the connecting lug to the tow lug. This connection structure is suitable for attaching implements to small agricultural machinery. However, for large machinery or when attaching heavy or large trailers, this connection method causes significant wear on the pin during driving and turning. Over time, this can easily lead to pin breakage and separation of the machinery and trailer. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a large agricultural machinery implement mounting device that uses a connecting shaft for movable connection, resulting in less wear and making it difficult for the cart bed and the machine body to detach.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0006] A large agricultural machinery implement mounting device includes a body connector and a truck bed connector. A mounting structure is provided between the body connector and the truck bed connector. The mounting structure includes a first fixed rod movably mounted on one side of the body connector and a second fixed rod movably mounted on one side of the truck bed connector. Fixed frames are fixedly mounted on the top and bottom of the first fixed rod. A motor is fixedly mounted on the top of the fixed frame. A screw connected to the motor is movably mounted inside the fixed frame. A movable block is provided on the screw and is slidably connected to the fixed frame. A toothed plate is fixedly mounted on one side of the movable block. A connecting groove is provided at one end of the first fixed rod, and a toothed block is provided at one end of the second fixed rod.
[0007] Furthermore, two positioning grooves are symmetrically formed on the inner wall of the connecting groove, and two positioning rods are fixedly installed on both sides of the toothed block.
[0008] Furthermore, a protective frame is fitted onto the outside of the fixed frame and fixedly installed on the first fixed rod.
[0009] Furthermore, two support frames are symmetrically installed on one side of the toothed block, and two support rods movably connected to the support frames are installed on one side of the second fixing rod. A buffer is provided between the toothed block and the second fixing rod.
[0010] Furthermore, both ends of the buffer are fixedly mounted with fixing plates, and multiple bolts are installed between the two fixing plates and the tooth block and the second fixing rod.
[0011] Furthermore, rollers are fixedly installed on both sides of the support rod, and multiple grooves adapted to the rollers are formed on the inner wall of the support frame.
[0012] Furthermore, multiple reinforcing rods are fixedly installed on the surfaces of both the first and second fixing rods, and a support plate connected to the reinforcing rod is fixedly installed on the other end of both the first and second fixing rods.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This application replaces the traditional method of connecting the body connector and the truck bed connector with a mounting structure. After the first and second fixing rods on the body connector and the truck bed connector are fixedly connected by the meshing of the toothed plate and toothed block, the body connector and the truck bed connector are movably connected to the first and second fixing rods by a connecting shaft, which facilitates steering, thereby reducing wear and making the overall structure less prone to separation and breakage, and preventing the truck bed connector from detaching from the body connector.

[0020] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.
[0021] like Figures 1-4 As shown in the figure, this embodiment provides a large agricultural machinery equipment implement mounting device, which includes a body connector 1 and a truck bed connector 2. A mounting structure 3 is provided between the body connector 1 and the truck bed connector 2. The mounting structure 3 includes a first fixing rod 4 movably installed on one side of the body connector 1 and a second fixing rod 5 movably installed on one side of the truck bed connector 2. A fixing frame 6 is fixedly installed at the top and bottom of the first fixing rod 4. A motor 7 is fixedly installed at the top of the fixing frame 6. A screw 8 connected to the motor 7 is movably installed inside the fixing frame 6. A movable block 9 is provided on the screw 8 through a threaded connection, and the movable block 9 is slidably connected to the fixing frame 6. A toothed plate 10 is fixedly installed on one side of the movable block 9. A connecting groove 11 is opened at one end of the first fixing rod 4, and a toothed block 12 is provided at one end of the second fixing rod 5. This application, through the setting of the mounting structure 3, connects the second fixing rod 5 at one end of the truck bed connector 2 with the first fixing rod 4 at one end of the body connector 1. The toothed block 12 at one end of the second fixing rod 5 is inserted into the connecting groove 11 opened at one end of the first fixing rod 4. Then, the motor 7 is started to drive the screw 8 to rotate, so that the screw 8 drives the toothed plate 10 to move through the moving block 9, so that the two toothed plates 10 mesh with the toothed block 12. Under the action of meshing, the first fixing rod 4 and the second fixing rod 5 are fixed, thereby connecting the body connector 1 and the truck bed connector 2. Since the body connector 1 and the truck bed connector 2 are both connected to the first fixing rod 4 and the second fixing rod 5 by a connecting shaft, it is convenient to turn, thereby reducing wear and making the overall structure less prone to separation and breakage, and preventing the truck bed connector 2 from detaching from the body connector 1.
[0022] In this embodiment, as Figures 1-4As shown, two positioning grooves 13 are symmetrically opened on the inner wall of the connecting groove 11, and two positioning rods 14 are fixedly installed on both sides of the toothed block 12. With the setting of positioning grooves 13 and positioning rods 14, when the first fixing rod 4 and the second fixing rod 5 are connected, the toothed block 12 can be accurately positioned and connected at the center of the connecting groove 11, so that the two toothed plates 10 can better mesh with the toothed block 12 and improve the tightness of the installation.
[0023] A protective frame 15 is fitted on the outside of the fixed frame 6 and fixedly installed on the first fixed rod 4. Two support frames 16 are symmetrically installed on one side of the toothed block 12. The protective frame 15 can enclose the motor 7 on the fixed frame 6 and protect the motor 7.
[0024] Two support rods 17, which are movably connected to the support frame 16, are fixedly installed on one side of the second fixed rod 5. A buffer 18 is provided between the toothed block 12 and the second fixed rod 5. During deceleration, the truck bed connector 2 will impact forward due to inertia. With the action of the buffer 18 and the cooperation of the support frame 16 and the support rods 17, the forward impact force of the truck bed connector 2 can be buffered and reduced, thereby reducing the impact force on the toothed block 12 and the toothed plate 10 and preventing damage to the toothed plate 10 and the toothed block 12.
[0025] In this embodiment, as Figures 1-4 As shown, both ends of the buffer 18 are fixedly installed with fixing plates 19, and multiple bolts 20 are installed between the two fixing plates 19 and the toothed block 12 and the second fixing rod 5. The buffer 18 is installed between the second fixing rod 5 and the toothed block 12 by using fixing plates 19 and bolts 20, which not only makes the installation secure enough to prevent it from falling off, but also facilitates the disassembly and replacement of the buffer 18.
[0026] Rollers 21 are fixedly installed on both sides of the support rod 17, and multiple grooves 22 adapted to the rollers 21 are opened on the inner wall of the support frame 16. Under the rolling action of the rollers 21, the friction generated when the support rod 17 moves in the support frame 16 can be reduced, the resistance between the support frame 16 and the support rod 17 can be reduced, and the buffer 18 can better buffer.
[0027] Multiple reinforcing rods 23 are fixedly installed on the surfaces of both the first fixing rod 4 and the second fixing rod 5. Support plates 24 connected to the reinforcing rods 23 are fixedly installed on the other ends of both the first fixing rod 4 and the second fixing rod 5. The multiple reinforcing rods 23 form a triangular structure distributed on the first fixing rod 4 and the second fixing rod 5, further enhancing the structural strength of the first fixing rod 4 and the second fixing rod 5.
[0028] The working process of the large agricultural machinery equipment implement mounting device provided in this embodiment is as follows: The second fixing rod 5 at one end of the truck bed connector 2 is connected to the first fixing rod 4 at one end of the machine body connector 1. The tooth block 12 at one end of the second fixing rod 5 is inserted into the connecting groove 11 opened at one end of the first fixing rod 4. Then, the motor 7 is started to drive the screw 8 to rotate, so that the screw 8 drives the tooth plate 10 to move through the moving block 9, so that the two tooth plates 10 and the tooth block 12 mesh. Under the action of meshing, the first fixing rod 4 and the second fixing rod 5 are fixed, thereby connecting the machine body connector 1 and the truck bed connector 2. Since the machine body connector 1 and the truck bed connector 2 are both connected to the first fixing rod 4 and the second fixing rod 5 by a connecting shaft, it is convenient to turn.
