Description

Technical Field

[0001] The utility model relates to the field of tractor implement connection devices, in particular to a tractor implement quick connection device. Background Art

[0002] A tractor implement quick-connect device is a device specifically designed for connecting tractors to various implements. It typically consists of a connecting component, a locking mechanism, and an operating handle. The connecting component closely mates with the tractor's power output and the implement's interface. The locking mechanism quickly and securely secures the connection, while the operating handle facilitates connection and removal. This device makes connecting tractors to implements efficient and convenient, saving time during installation and replacement of implements, improving agricultural production efficiency, and providing reliable technical support for the rapid switching of tractors between various implements in different operating scenarios.

[0003] After searching, the Chinese patent with the announcement number CN212463959U discloses a quick connection device for a tractor and a tillage implement. The patent records that by setting the main frame, the upper hook, the lower hook, the upper hook fixing assembly, the locking assembly, the latch, the cotter pin and the connecting assembly, the quick connection device is connected to the tractor through the upper hook fixing assembly, the latch and the cotter pin, and the rear end of the tillage implement only needs to be hung on the upper hook and the lower hook of the quick connection device, and the lower hook is locked by the locking assembly, so that the tillage implement is quickly locked to the quick connection device. The quick connection device is connected to the tractor, which greatly improves the convenience of disassembly and assembly of the tillage implement compared to the traditional direct connection between the tillage implement and the tractor, which requires repeated disassembly and assembly of bolts when replacing the tillage implement, thereby greatly improving the technical solution of farming efficiency.

[0004] In this solution, although the portability of installation and disassembly is achieved, when the device connector is connected to equipment such as machinery and tools, when the equipment and tractor are running or suddenly stopped, the internal parts of the connector will directly collide with the external equipment, which will directly cause damage to the connector over time and reduce the service life of the connector. In order to solve this technical problem, the utility model proposes a tractor tool quick connection device. Utility Model Content

[0005] (1) Technical problems solved

[0006] In this solution, although the portability of installation and disassembly is achieved, when the device connector is connected to equipment such as machinery and tools, when the equipment and tractor are running or suddenly stopped, the internal parts of the connector will directly collide with the external equipment, which will directly cause damage to the connector over time and reduce the service life of the connector. In order to solve this technical problem, the utility model proposes a tractor tool quick connection device.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a quick connection device for tractor implements, including a connecting frame, a receiving block is slidably connected to the inside of the connecting frame, the outer wall of the receiving block is fixedly connected to a U-shaped frame, a connecting column is provided inside the U-shaped frame, a connecting piece is provided at the other end of the connecting column, an inner cavity is opened inside the connecting piece, a damping rod is fixedly connected to the other end of the connecting column, a limiting ring is fixedly connected to the other end of the damping rod, and a spring is fixedly connected between the limiting ring and the connecting column, and a set of springs is provided on the outer wall of the damping rod, and the limiting ring is slidably connected in the inner cavity.

[0009] Preferably, both side walls of the limiting ring are fixedly connected with sliders, a pair of inner grooves are opened inside the connecting piece, and the sliders are slidably connected in the inner grooves, and a second spring is fixedly connected to the slider and the inner wall of the inner groove.

[0013] Preferably, a main frame is provided outside the connecting frame, and the connecting frame is fixedly connected to the outer wall of the main frame by screws.

[0014] (3) Beneficial effects

[0015] The utility model provides a tractor implement quick connection device, which has the following beneficial effects:

[0016] (1) In this device, one end of the connecting column is connected to the connecting piece of the machine. When the machine is moving or the tractor stops suddenly, forces in different directions are generated on the connecting column. The limiting ring on the connecting column moves in the inner cavity, and when it moves, it drives the sliders at both ends to move in the inner groove. When the machine moves and generates a pulling force, the slider moves outward in the inner groove to pull the spring 2. The spring 2 uses the rebound elasticity to buffer. When the tractor stops suddenly, the connecting column is squeezed into the connecting piece due to inertia, and the limiting ring presses against the inner wall of the inner cavity. At this time, the damping force of the damping rod and the rebound elasticity of the spring 1 work together to block it. This combination solves the problem that the existing tractor and machine connection device is prone to impact damage to the equipment during operation and emergency stop. The traditional device may lack an effective buffering and blocking mechanism, which makes the equipment easily damaged. This combination effectively protects the equipment through the synergistic effect of the spring 2, the damping rod and the spring 1, and improves the stability and reliability of the connection device.

[0017] (2) The connecting column on the connecting piece is inserted into the U-shaped frame outside the receiving block, and the first pin is inserted after the second socket corresponds to the first socket, so that the connecting piece can be rotated left and right in the U-shaped frame, which is convenient for connecting with the tractor and the implement. When there is a distance difference in the connection, the second pin is pulled out and the connecting piece is pulled outward. The connecting piece slides in the slide groove through the rotating rod on the receiving block at the other end, moves to the appropriate position so that the second inner hole corresponds to the first inner hole on the connecting frame, and then the second pin is inserted to fix it. This matching method solves the problem that the existing tractor and implement connection device is inflexible and difficult to adjust the distance. The traditional device cannot adapt to different distance requirements due to its fixed connection method. This matching method achieves the effect of fast connection and flexible distance adjustment, improves the connection efficiency, meets the actual needs of tractor and implement connection in different operating scenarios, and enhances the versatility and practicality of the device.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: A quick connection device for tractor implements, comprising a connecting frame 1, a receiving block 2 being slidably connected inside the connecting frame 1, a U-shaped frame 3 being fixedly connected to the outer wall of the receiving block 2, a connecting column 8 being provided inside the U-shaped frame 3, a connecting member 7 being provided at the other end of the connecting column 8, an inner cavity 16 being opened inside the connecting member 7, a damping rod 9 being fixedly connected at the other end of the connecting column 8, a limiting ring 10 being fixedly connected at the other end of the damping rod 9, and a spring 11 being fixedly connected between the limiting ring 10 and the connecting column 8, and the spring 11 being sleeved on the outer wall of the damping rod 9, and the limiting ring 10 being slidably connected in the inner cavity 16, sliders 15 being fixedly connected to both side walls of the limiting ring 10, a pair of inner grooves 12 being opened inside the connecting member 7, and the slider 15 being slidably connected in the inner groove 12, and a spring 2 14 being fixedly connected to the slider 15 and the inner wall of the inner groove 12.

[0026] After the connector 7 is connected to the implement, the movement of the implement generates a pulling force on the connector 7 during its movement. At this point, because the connecting post 8 is fixed within the retaining U-shaped frame 3, the connector 7 slides outward. This sliding movement causes the retaining ring 10 at one end of the connector 8 to move outward within the inner cavity 16. As the retaining ring 10 moves, it drives the sliders 15 at both ends to move within the inner groove 12. As the sliders 15 move outward within the inner groove 12, they pull on spring 2 14. Spring 2 14 uses its resilience to buffer this pulling force. If the tractor suddenly stops, the connector 8 presses into the connector 7 due to inertia. This compression forces the retaining ring 10 to move and press against the inner wall of the inner cavity 16. At this point, the damping force of the damping rod 9 and the resilience of spring 11 act together to prevent the connector 8 from directly impacting the connector 7, effectively protecting the equipment. During the connection process between the machine and the tractor, whether in motion or in the case of sudden stop, it can provide good protection for the equipment, reduce the risk of equipment damage caused by impact force, and improve the service life and stability of the equipment.

[0027] Example 2: The difference between this example and Example 1 is that, a socket 1 5 is provided inside the U-shaped frame 3, a socket 2 6 is provided inside the connecting column 8, and the connecting column 8 is connected by a pin 1 4, which penetrates the socket 2 6 and extends to the outside of the socket 1 5, and sliding grooves 21 are provided on both sides of the connecting frame 1, a rotating rod 17 is provided inside the receiving block 2, and the rotating rod 17 is slidably connected in the sliding groove 21, and the receiving block 2 is slidably connected in the connecting frame 1, and a plurality of inner holes 19 are provided inside the connecting frame 1, and the rotating rod 17 is provided with an inner hole 20, and at the same time, the pin 2 18 penetrates the inner hole 20 and extends to the outside of the connecting frame 1, and a main frame 22 is provided outside the connecting frame 1, and the connecting frame 1 is fixedly connected to the outer wall of the main frame 22 by screws 13.

[0028] Use screws 13 to securely attach the connecting frame 1 to the main frame 22. Next, insert the connecting post 8 on the connector 7 into the U-shaped frame 3 outside the receiving block 2, ensuring that the second socket 6 aligns with the first socket 5. Then, connect by inserting the first latch 4. This connection allows the connector 7 to rotate left and right within the U-shaped frame 3 via the connecting post 8. At this point, the tractor implement can be connected via the connector 7. If there is a gap in the connection distance, pull out the second latch 18 and pull the connector 7 outward. The connector 7 is restrained and slides within the slide groove 21 by the rotating rod 17 on the other end of the receiving block 2. After moving to the appropriate position and with the second inner hole 20 aligned with the first inner hole 19 on the connecting frame 1, insert the second latch 18 to secure it, achieving a quick connection. This connection greatly improves connection efficiency, reduces the time and labor required, and makes connecting tractor implements more convenient and faster, meeting the needs of actual use.

[0029] Working principle: Use screws 13 to fix the connecting frame 1 on the main frame 22, then insert the connecting column 8 on the connecting piece 7 into the U-shaped frame 3 outside the receiving block 2, and the second socket 6 corresponds to the first socket 5. Then insert the pin 1 4 to connect, so that the connecting piece 7 can be rotated left and right in the U-shaped frame 3 through the connecting column 8. At this time, the tractor tool is connected through the connecting piece 7. When there is a distance difference during connection, pull out the second pin 18 and pull the connecting piece 7 outward. The connecting piece 7 is limited and slides in the slide groove 21 through the rotating rod 17 on the receiving block 2 at the other end. After moving to the appropriate position, and the inner hole 20 corresponds to the inner hole 19 on the connecting frame 1, insert the second pin 18 to fix it, and through the cooperation between them , achieving the effect of quick connection, the connecting piece 7 is connected to the machine, and during the movement, the connecting piece 7 will be pulled. At this time, since the connecting column 8 is fixed in the limiting U-shaped frame 3, the connecting piece 7 slides outward, causing the limiting ring 10 at one end of the connecting column 8 to move outward in the inner cavity 16. When the limiting ring 10 moves, it will drive the sliders 15 at both ends to move in the inner groove 12. When the inner groove 12 moves outward, it will pull the spring 2 14, and the resilience of the spring 2 14 is used for buffering. When the tractor suddenly stops, the connecting column 8 will be squeezed into the connecting piece 7 due to inertia, driving the limiting ring 10 to move and against the inner wall of the inner cavity 16. At this time, the damping force of the damping rod 9 and the resilience of the spring 11 simultaneously exert force to block, thereby avoiding direct impact, thereby protecting the equipment.
