Description

Technical Field

[0001] The utility model relates to the field of resistance bars, in particular to a double resistance bar mechanism of a rice transplanter. Background Art

[0002] A rice transplanter's resistance bar is a tool used to assist the transplanter in planting rice seedlings. It is usually made of metal or plastic. It provides support and stability during transplanting, preventing the transplanter from sliding or slipping in the soil. This ensures uniform planting depth and spacing, improving transplanting efficiency and quality. The resistance bar can usually be adjusted and replaced according to different transplanter models and soil conditions to suit different operational needs.

[0003] However, the existing rice transplanter resistance bar generally needs to be disassembled and replaced in the use position, which is inconvenient. Therefore, it needs to be improved. Utility Model Content

[0008] Preferably, a clamping bead is fixedly connected to the inner side of the limiting sleeve, and the clamping bead is clamped with the pull rod. The setting of the clamping bead can increase the bonding strength between the limiting sleeve and the pull rod.

[0009] Preferably, a second spring is provided inside the convex pin, one end of the second spring is fixedly connected to the square rod, and the other end of the second spring is fixedly connected to the inner surface of the convex pin. By providing the second spring, an elastic force can be applied to the square rod.

[0010] Preferably, both the left and right sections of the shaft are fixedly connected to limit rings, which are in contact with the mounting ears. The setting of the limit rings has a limiting effect on the position of the shaft installed on the mounting ears.

Two resistance rods 3 are fixedly connected to the middle section of the shaft 2, spaced 90 degrees apart and at different heights. A swivel 4 made of stainless steel is welded to one end of the shaft 2. The swivel 4 facilitates the rotation of the shaft 2. Limiting rings 15 are fixedly connected to both the left and right ends of the shaft 2, contacting the mounting ears 1. The positioning of the limiting rings 15 limits the position of the shaft 2 on the mounting ears 1.

[0023] See also Figure 1-3 A locking sleeve 5 is fixedly connected to the surface of one of the mounting ears 1. A locking pin 6 is slidably connected to the interior of the locking sleeve 5. The locking pin 6 is plugged into the rotating shaft 2. Two locking grooves are provided on the rotating shaft 2, and the ends of the locking pin 6 are located in the locking grooves. The provision of the locking grooves facilitates the insertion of the locking pin 6 into the rotating shaft 2. Moreover, the number and position of the rotating shaft 2 correspond to the resistance rod 3. A spring 7 is provided inside the locking sleeve 5. One end of the spring 7 is fixedly connected to the locking pin 6, and the other end of the spring 7 is fixedly connected to the inner surface of the locking sleeve 5. The provision of the spring 7 allows elastic force to be applied to the locking pin 6. A pull rod 8 is fixedly connected to the pin body of the locking pin 6. The pull rod 8 passes through the locking sleeve 5 and is slidably connected to the locking sleeve 5.

[0024] See also Figure 3The lock sleeve 5 is internally connected to a convex pin 9 for rotation, and the convex pin 9 is internally connected to a square rod 10 for sliding movement. The end of the square rod 10 is fixedly connected to a connecting strip 11, and the end of the connecting strip 11 is fixedly connected to a limiting sleeve 12, which is slidably connected to the pull rod 8. The inner side of the limiting sleeve 12 is fixedly connected to a clamping bead 13, which is clamped to the pull rod 8. The provision of the clamping bead 13 can increase the bonding strength between the limiting sleeve 12 and the pull rod 8. A spring 2 14 is provided inside the convex pin 9, one end of which is fixedly connected to the square rod 10, and the other end of which is fixedly connected to the inner surface of the convex pin 9. The provision of the spring 2 14 can apply elastic force to the square rod 10.

[0025] The specific implementation process of the present utility model is as follows: when in use, first pull the locking pin 6 through the pull rod 8, so that the locking pin 6 slides in the locking sleeve 5 and compresses the spring 1 7, and then the locking pin 6 disengages from the rotating shaft 2, so that the restriction on the rotating shaft 2 can be released, and then the rotating shaft 2 is rotated through the swivel 4, so that the positions of the two resistance rods 3 on the rotating shaft 2 are replaced, which is more convenient than the previous method of removing the resistance rod 3 to replace the position. After adjusting the position, release the pull rod 8, and the locking pin 6 will be reset under the action of the spring 1 7, and inserted into the rotating shaft 2 to lock and fix the rotating shaft 2. In addition, the limiting sleeve 12 at the end of the connecting bar 11 is rotated to the pull rod 8 and sleeved on the end of the pull rod 8, so that the pull rod 8 and the locking pin 6 can be locked, thereby ensuring the stability of the rotating shaft 2 after rotation.
