Abstract

A vegetable transplanting device includes a robotic arm, a positioning ring fixedly disposed on an outside of the robotic arm, and a transplant assembly connected to the robotic arm. The transplant assembly includes: a motor fixedly disposed at an end of the robotic arm; a fixing frame fixedly mounted on a side surface of the positioning ring away from the robotic arm; a worm screw fixedly disposed at an output end of the motor; first fixing rods fixedly disposed and passing through the fixing frame; worm gears, each rotatably installed on an outside of one of the first fixing rods, the worm gears being engaged with the worm screw by teeth; connecting rod assemblies, each rotatably installed on the outside of at least one of the first fixing rods; and clamping members, each rotatably connected to one end of the corresponding connecting rod assembly away from the fixing frame.

Claims (57)

1. A vegetable transplanting device comprising:

a robotic arm;

a positioning ring fixedly disposed on an outside of the robotic arm; and

a transplant assembly connected to the robotic arm, comprising:

a motor fixedly disposed at an end of the robotic arm;

a fixing frame fixedly mounted on a side surface of the positioning ring away from the robotic arm;

a worm screw fixedly disposed at an output end of the motor;

first fixing rods fixedly disposed and passing through the fixing frame;

one or more worm gears, each rotatably installed on an outside of one of the first fixing rods, the worm gear being engaged with the worm screw by teeth;

connecting rod assemblies, each rotatably installed on the outside of at least one of the first fixing rods; and

clamping members, each rotatably connected to one end of the corresponding connecting rod assembly away from the fixing frame.

2. The device according to claim 1 , wherein a longitudinal section of the fixing frame is a U shape with a ninety-degree rotation, and the fixing frame is rotatably connected to the positioning ring.

3. The device according to claim 1 , wherein:

a quantity of the first fixing rods is four;

the first fixing rods are distributed in the fixing frame and in parallel with a side wall of the fixing frame; and

each of the one or more worm gears is rotatably connected to a corresponding one of the first fixing rods close to the worm screw.

4. The device according to claim 1 , wherein each connecting rod assembly comprises:

a first connecting rod rotatably connected to two of the first fixing rods close to the worm screw, and fixedly connected to the corresponding worm gear; and

a second connecting rod in parallel with the first connecting rod, and rotatable connected to other two of the first fixing rods away from the worm screw.

5. The device according to claim 4 , wherein:

the clamping member has an L shape;

a side surface of the clamping member facing the fixing frame is provided with a notch; and

ends of the first connecting rod and the second connecting rod are rotatably connected to the clamping member at the notch.

6. The device according to claim 1 , wherein:

the device comprises two of the clamping members; and

each of the two clamping members are configured with a clamping groove on a side surface facing the other clamping member, the clamping grooves are configured to be compatible with a seedling ring, the seedling ring being used to protect a vegetable to be transplanted.

7. The device according to claim 1 , wherein:

two ends of each of the first fixing rods are installed to the fixing frame with bolts.

8. The device according to claim 1 , further comprising:

second fixing rods, two ends of each of the second fixing rods are installed to the corresponding clamping member with bolts.

9. A transplant assembly used in a vegetable transplanting device, comprising:

a motor fixedly disposed at an end of a movable arm of the vegetable transplanting device;

a fixing frame fixedly mounted on a side surface of a positioning ring away from the movable arm;

a worm screw fixedly disposed at an output end of the motor;

first fixing rods fixedly disposed and passing through the fixing frame;

one or more worm gears, each rotatably installed on an outside of one of the first fixing rods, the worm gear being engaged with the worm screw by teeth;

connecting rod assemblies, each rotatably installed on the outside of at least one of the first fixing rods; and

clamping members, each rotatably connected to one end of the corresponding connecting rod assembly away from the fixing frame.

10. The transplant assembly according to claim 9 , wherein a longitudinal section of the fixing frame is a U shape with a ninety-degree rotation, and the fixing frame is rotatably connected to the positioning ring.

11. The transplant assembly according to claim 9 , wherein:

a quantity of the first fixing rods is four;

the first fixing rods are distributed in the fixing frame and in parallel with a side wall of the fixing frame; and

each of the one or more worm gears is rotatably connected to a corresponding one of the first fixing rods close to the worm screw.

12. The transplant assembly according to claim 9 , wherein each connecting rod assembly comprises:

a first connecting rod rotatably connected to two of the first fixing rods close to the worm screw, and fixedly connected to the corresponding worm gear; and

a second connecting rod in parallel with the first connecting rod, and rotatable connected to other two of the first fixing rods away from the worm screw.

13. The transplant assembly according to claim 12 , wherein:

the clamping member has an L shape;

a side surface of the clamping member facing the fixing frame is provided with a notch; and

ends of the first connecting rod and the second connecting rod are rotatably connected to the clamping member at the notch.

14. The transplant assembly according to claim 9 , wherein:

the device comprises two of the clamping members; and

each of the two clamping members are configured with a clamping groove on a side surface facing the other clamping member, the clamping grooves are configured to be compatible with a seedling ring, the seedling ring being used to protect a vegetable to be transplanted.

15. The transplant assembly according to claim 9 , wherein:

two ends of each of the first fixing rods are installed to the fixing frame with bolts.

16. The transplant assembly according to claim 9 , further comprising:

second fixing rods, two ends of each of the second fixing rods are installed to the corresponding clamping member with bolts.
