By providing the reset assembly, the first connecting rod 4221 is always kept in a tightened state, so that the laminating roller 41 is in a retracted position.

[0056] The specific transmission process of the coating roller 41 is as follows: the vertical transmission shaft 63 transmits the power of the main transmission shaft 61 to the first spur gear 431, and the rotation of the vertical transmission shaft 63 along the axis in the up-down direction is converted into the rotation along the axis extending laterally through the cooperation of the bevel gear structure. The first spur gear 431 is meshed with the second spur gear 432 to drive the second spur gear 432 to rotate, and then drive the dial 44 and the lever 441 set on the dial 44 to rotate. According to the design of the overall structure, when the coating roller 41 is required to perform a coating action, the The dial 44 just rotates to a certain angle, at which time the lever 441 abuts against the convex rod 4212, thereby driving the rotating shaft 421 to rotate, and the sliding rod 423 is driven by the fourth connecting rod assembly 422 to push the coating roller 41 to move in the longitudinal direction, so as to cover the soil surface with a water-retaining film. When the coating roller 41 moves to the farthest end, the dial 44 rotates to a certain angle, at which time the lever 441 separates from the convex rod 4212, and the first connecting rod 4221 is driven by the reset assembly to return to the tightened position, thereby driving the coating roller 41 to retract.

[0057] It can be understood that the reset component can be a torsion spring arranged on the rotating shaft 421, or the reset component can be a protrusion arranged on the first connecting rod 4221, and the protrusion and the frame 1 are connected by an elastic member to keep the first connecting rod 4221 in the tightened position.

The water tank 311 and the fertilizer tank 312 are connected to the hollow cavity of the shovel 21 through the feeding pipe 32. When the shovel 21 finishes digging the pit, the switch assembly 321 is controlled to open, and water and fertilizer can be irrigated through the discharge port 211.

[0061] Furthermore, in order to coordinate the digging action and watering timing of the shovel 21, the switch assembly 321 is also controlled by the secondary transmission shaft.

By setting the initial angle of the crank in the crank rocker mechanism 34 and the length of the crank and the rocker, when the feeding pipe 32 is in the open state, the two pistons 33 are in the state of downward movement and compression, so that the water and fertilizer in the water tank 311 and the fertilizer tank 312 can flow out quickly.

[0063] The two pistons 33 can act simultaneously, or the piston 33 of the fertilizer tank 312 can move downward and compress first, and then the piston 33 of the water tank 311 can move downward and compress.

[0064] In the technical solution of the present invention, in the initial state, the two shovels 21 are in an open state along the lateral interval. When they are needed, it is only necessary to start the drive motor 5. The drive motor 5 first drives the two shovels 21 to move toward each other and downward along the lateral direction through the transmission assembly 6 to form a pit around the tree trunk; after the pit is excavated, the two shovels 21 are opened horizontally and moved upward to reset, and at the same time, the switch assembly 321 is turned on, and the water and fertilizer in the storage container 31 are transported to the discharge port 211 through the feeding pipe 32 and evenly spread in the pit; after the two shovels 21 are fully opened, the coating roller 41 moves longitudinally to cover a layer of water-retaining film on the upper side of the pit to prevent water from evaporating and losing, and when the coating roller 41 moves to the farthest end, the cutter 45 moves downward to cut off the water-retaining film to complete the laying, and the coating roller 41 is reset; after the coating roller 41 is reset, the two shovels 21 move toward each other along the lateral direction to backfill the previously excavated soil above the water-retaining film, completing an automatic filling and watering process. The water-saving irrigation device 100 in this solution increases the water absorption area of ​​plant roots and the storage time of water in the soil through a series of processes such as digging holes, filling and watering, covering with film and covering with soil. The operation of each mechanism is controlled by the transmission component 6 to realize the automation of the above actions, and the structure is reliable, low cost and easy to use.
