Description

Technical Field

[0001] The utility model relates to the technical field of rice transplanters, in particular to a novel power transmission device for rice transplanters. Background Art

[0002] A rice transplanter is an agricultural machine used to plant rice seedlings in rice fields. To begin planting, a robotic gripper first removes several rice seedlings from the seedbed and plants them in the soil. To maintain a right angle between the seedbed and the ground, the front end of the gripper must move in an elliptical motion.

In this way, when the transplanting head contacts the stone, the power has not changed, which causes damage to the power rod wall and the seedlings. The use effect is not ideal.

[0019] Referring to Figures 1-4 A new rice transplanter power transmission device, comprising a support rod 1, the rear end of the support rod 1 is fixedly connected with a connecting rod 4, the connecting rod 4 is used for fixedly connecting with the body of the device, the two sides of the connecting rod 4 are both provided with a rice transplanting movement device 6, which can realize the rice transplanting action, which is the prior art, the front end of the rice transplanting movement device 6 is fixedly connected with a power arm 2, the power arm 2 can exert the rice transplanting action, the opposite side of the two rice transplanting movement devices 6 is fixedly connected with a power rod 3, the power rod 3 rotates, so that the assembly moves, the power rod 3 is fixedly connected with a round block 7, the outer side of the round block 7 is rotatably connected with a gear 5, the gear 5 is used for receiving power, the inside of the gear 5 is uniformly provided with a groove 11, the inside of the groove 11 is slidably connected with a clamping block 10, one side of the clamping block 10 is fixedly connected with a spring 9, the spring 9 has a certain supporting force on the clamping block 10, the other side of the spring 9 is fixedly connected with the inside of the groove 11, the outer side of the round block 7 is uniformly provided with a clamping groove 12;

[0020] When working, the power is set to rotate, so that the gear 5 rotates, the gear 5 drives the clamping block 10 to rotate when rotating, the clamping block 10 is located in the inside of the clamping groove 12 at this time, and then the clamping block 10 drives the round block 7 to rotate, the round block 7 drives the power rod 3, and then the rice transplanting work is realized. When the rice transplanting process encounters a relatively solid object, the rotating resistance of the power rod 3 becomes larger at this time, the clamping block 10 moves to the inside of the groove 11 under the action of the force at this time, and then the gear 5 rotates relative to the round block 7, and then the power rod 3 is not forced to power. In this way, when the rice transplanting work encounters a relatively hard object, the gear 5 and the round block 7 can rotate relative to each other, so that the assembly can not be overloaded when working, and the applicability of the device is improved.
