Description

Technical Field

[0001] This utility model relates to the field of double-furrow plow technology, and in particular to a double-furrow plow reversing device with limit protection. Background Technology

[0002] With the advancement of science and technology, agricultural tools are also evolving. Currently, the most common tool used for ditch digging and soil loosening is the double-furrow plow. However, the double-furrow plow has some defects and shortcomings, specifically requiring improvement as follows: 1. The double-furrow plow tends to flip under its own weight during use, meaning its angle is not stable, causing inconvenience. 2. Furthermore, the lower iron plow blades of a typical double-furrow are inconvenient to store when not in use, become dull due to friction with the ground, and are difficult to replace. Therefore, we propose a double-furrow plow flipping device with limit protection. Utility Model Content

[0003] The main purpose of this utility model is to provide a double-furrow plow overturning device with limit protection, which can effectively solve the problems in the background art.

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

[0005] A double-furrow plow overturning device with limit protection includes a limit mechanism. The front and rear ends of the limit mechanism are fixedly connected to connecting plates. Bolts are inserted through both sets of connecting plates. A rocker arm is movably arranged inside the limit mechanism via a rotating shaft. Two sets of recovery mechanisms are fixedly arranged on the rocker arm. A side rod is fixedly connected to the rear end of the rocker arm. A side wheel is fixedly connected to the lower end of the side rod.

[0006] Preferably, the limiting mechanism includes a spiral frame, with several sets of convenient rollers movably arranged on the upper and lower inner walls of the spiral frame. Several sets of No. 1 positioning holes are equally spaced on the upper left side and lower left side of the spiral frame. Folded plates are fixedly connected to the middle of the upper end and the middle of the lower end of the spiral frame. An extension cylinder is fixedly connected to the far end of each of the two sets of folded plates. A rotating fixing rod is threaded and engaged inside each of the two sets of extension cylinders.

[0007] By adopting the above technical solution, several sets of No. 1 positioning holes are opened on the upper right end and the lower right end of the rocker arm.

[0008] Preferably, the herringbone frame is fixedly connected to the connecting plate, the rotating fixing rod is inserted and snapped into the nearest positioning hole, and a rocker arm is movably connected inside the herringbone frame through a rotating shaft. The surface of the rocker arm contacts but is not fixed to several sets of convenient rollers.

[0009] By adopting the above technical solution, the rotating fixed rod and the No. 1 positioning hole on the rocker arm are also interlocked and snapped together to fix the angle and position of the rocker arm, preventing the rocker arm from swinging and colliding with the structure and causing damage.

[0010] Preferably, the recycling mechanism includes a lower cover plate and an upper cover plate. Two sets of positioning rods are fixedly connected to the upper end of the lower cover plate, and two sets of No. 2 fixing holes are opened on the upper cover plate. Mounting plates are fixedly connected to the front and rear of the lower end of the lower cover plate. Two sets of round holes are opened on both sets of mounting plates, and an iron plow mechanism is movably connected between the two sets of mounting plates via a common pivot.

[0011] By adopting the above technical solution: a second positioning hole is opened on the rocker arm, and the positioning rod passes through the second positioning hole on the rocker arm.

[0012] Preferably, the iron plow mechanism includes a tilting frame, with receiving holes at both the front and rear ends of the tilting frame. Springs are fixedly connected to the inner walls of both sets of receiving holes, and a snap-fit ​​rod is fixedly connected to the far end of each set of springs. A channel-opening plow blade is fixedly connected to the lower end of the tilting frame.

[0013] By adopting the above technical solution, the ditch-opening plow blades are set at an angle, making it easy to embed them into the ground.

[0014] Preferably, the snap-fit ​​rod passes through the adjacent circular hole, and the positioning rod passes through the second fixing hole.

[0015] By adopting the above technical solution: the snap rod passes through the round hole, allowing the ditch-opening plow blade to be lowered or retracted, and the upper and lower cover plates can be easily disassembled without shifting during use.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting a limiting mechanism, the rocker arm that is movably inserted inside the loop frame on the limiting mechanism can change its angle. However, in actual use, the rotating fixing rod on the folding plate can be inserted and locked with the first fixing hole to fix the angle of the rocker arm and prevent the rocker arm from swinging excessively and causing collision damage.

[0018] 2. By setting up a recycling mechanism, the upper and lower cover plates of the recycling mechanism are connected to the rocker arm through a positioning rod. The positioning rod passes through the rocker arm to prevent the rod from moving during the channel opening process and to prevent excessive compression of the rocker arm. At the same time, the locking rod of the lower flip frame can be used to lower the channel opening plow blade or recycle it when not in use to prevent wear. Attached Figure Description

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A double-furrow plow overturning device with limit protection includes a limit mechanism 1. The front and rear ends of the limit mechanism 1 are fixedly connected to connecting plates 2. Bolts 3 are inserted on both sets of connecting plates 2. A rocker arm 4 is movably arranged inside the limit mechanism 1 through a rotating shaft. Two sets of recovery mechanisms 5 are fixedly arranged on the rocker arm 4. A side rod 6 is fixedly connected to the rear end of the rocker arm 4. A side wheel 7 is fixedly connected to the lower end of the side rod 6.

[0029] In this embodiment, the limiting mechanism 1 includes a U-shaped frame 8. Several sets of convenient rollers 9 are movably arranged on the upper and lower inner walls of the U-shaped frame 8. Several sets of No. 1 positioning holes 10 are equally spaced on the upper left side and the lower left side of the U-shaped frame 8. Folded plates 11 are fixedly connected to the middle of the upper end and the middle of the lower end of the U-shaped frame 8. The ends of the two sets of folded plates 11 that are far apart are fixedly connected to the U-shaped frame 8 and the connecting plate 2. The rotating fixing rod 13 is inserted and snapped into the adjacent No. 1 positioning hole 10. A rocker rod 4 is movably connected inside the U-shaped frame 8 through a rotating shaft. The surface of the rocker rod 4 contacts several sets of convenient rollers 9 but does not fix the extension cylinder 12. The rotating fixing rod 13 is threaded and snapped into the interior of the two sets of extension cylinders 12.

[0030] With the above solution: the rocker arm 4 and the loop frame 8 are connected by a rotating shaft, and the first positioning hole 10 on the rocker arm 4 is inserted and locked with the rotating fixing rod 13 threaded through the folded plate 11, which can be used to fix the angle and position of the rocker arm 4. In any case, the rocker arm 4 can be easily rocked due to the swing caused by gravity, and the convenient roller 9 set inside the loop frame 8 can be easily rocked.

[0031] In this embodiment, the recycling mechanism 5 includes a lower cover plate 14 and an upper cover plate 15. Two sets of positioning rods 16 are fixedly connected to the upper end of the lower cover plate 14. Two sets of second fixing holes 17 are opened on the upper cover plate 15. Mounting plates 18 are fixedly connected to the front and rear of the lower end of the lower cover plate 14. Two sets of round holes 19 are opened on the two sets of mounting plates 18. The two sets of mounting plates 18 are movably connected to a common pivot axis. The iron plow mechanism 20 includes a flipping frame 21. The front and rear ends of the flipping frame 21 are opened with receiving holes 22. Springs 23 are fixedly connected to the inner walls of the two sets of receiving holes 22. A locking rod 24 is fixedly connected to the far end of the two sets of springs 23. A channel-opening plow blade 25 is fixedly connected to the lower end of the flipping frame 21. The locking rod 24 passes through the adjacent round hole 19, and the positioning rod 16 passes through the second fixing hole 17.

[0032] With the above solution, the lower cover plate 14 and the upper cover plate 15 are fixed by the positioning rod 16 passing through the second fixing hole 17 on the rocker arm 4. The other way is to disassemble. The operation is simple. Since the positioning rod 16 will not move during use, and the snap-fit ​​rod 24 set in the receiving hole 22 on the lower flip frame 21 is engaged with the round hole 19, the angle of the flip frame 21 can be fixed, which makes it convenient to put down the lower channel-opening plow blade 25 for work or storage.

[0033] It should be noted that this utility model is a double-furrow plow turning device with limit protection. During use, firstly, according to the actual situation, the rotating fixing rod 13 on the folding plate 11 is pulled out from the first positioning hole 10. Then, the rocker arm 4 can be rotated. Convenience rollers 9 are movably installed on both the upper and lower inner walls of the loop frame 8, allowing for easy movement of the rocker arm 4. After moving it to the appropriate position, the rotating fixing rod 13 is rotated in the opposite direction, causing it to engage with the nearest first positioning hole 10, thus fixing the angle and position of the rocker arm 4. Connect the connecting plate 2 and bolt 3 to the tractor. Then, pass the positioning rod 16 on the lower cover plate 14 through the second fixing hole 17 on the rocker arm 4, and then through the upper cover plate 15. After fixing with nuts, compress the spring 23 and the snap-fit ​​rod 24 inside the receiving hole 22 on the flip frame 21 so that it is disengaged from the upper round hole 19 and inserted into the lower round hole 19. This fixes the position of the ditch-opening plow blade 25, making it convenient for ditch opening and soil loosening. Conversely, inserting it into the upper round hole 19 will store it and prevent excessive friction with the ground.

[0034] 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 illustrative of the principles of this utility model.
