Description

Technical Field

[0001] This invention relates to the field of tree irrigation technology, specifically to a water-saving irrigation device and method suitable for sparse forest land. Background Technology

[0002] Sparse woodland refers to a type of woodland with low tree cover and large spacing between trees. It is usually distributed in arid, semi-arid, or topographically complex areas and has unique ecological characteristics and functional requirements. When irrigating this type of woodland, the large spacing between trees makes sprinkler irrigation extremely inefficient in terms of water resource utilization. Therefore, point-to-point irrigation has emerged, where individual trees are irrigated using irrigation devices. This not only facilitates control over the amount of irrigation water used but also ensures that the irrigation water directly reaches the root system, reducing water waste caused by evaporation and deep seepage.

[0003] Patent document CN106900498A discloses a water-saving irrigation device for forest land, including a water pump, a towerless water supply unit, a main water supply pipe, and branch water supply pipes. Multiple branch water supply pipes are provided, each with multiple connection joints. Each connection joint is equipped with a water supply device, which includes a control pipe and a ring-shaped diversion pipe. One end of the control pipe is connected to the connection joint and communicates with the inside of the branch water supply pipe. The other end of the control pipe is connected to the middle of the ring-shaped diversion pipe, which is a circular water pipe with a notch on the side opposite the connection point. This water-saving irrigation device for forest land is simple to operate, provides timely and effective water supply, and saves a significant amount of water. The water supply device can be recycled, saving costs. The addition of a manual water valve and hose to the control pipe allows for the application of liquid fertilizer or pesticides to seedlings based on routine pest and disease monitoring and soil nutrient testing results, facilitating biological management, improving tree survival rates, and accelerating forest land development. However, in actual production activities, the ring-shaped diversion pipe of the above-mentioned forest water-saving irrigation equipment does not have the function of adapting to plants of different diameters, which greatly reduces its applicability. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a water-saving irrigation device suitable for sparse woodlands to address the above-mentioned technical problems, so that the water-saving irrigation device can be applied to plants of different diameters.

[0005] The technical solution adopted in this invention is: a water-saving irrigation device suitable for sparse forest land, comprising:

[0050] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0051] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0054] Examples, such as Figures 1-12 As shown, a water-saving irrigation device suitable for sparse woodland includes: a housing 10, a sliding rack 20, an arc-shaped gripper 30, a transmission gear 50, a water inlet pipe 60, and an adjusting handle 70.

[0055] The housing 10 is hollow inside, and a clearance groove 11 is formed on the top of the housing 10 along the longitudinal direction. The clearance groove 11 communicates with the inner cavity of the housing 10.

[0056] The sliding rack 20 is installed in the inner cavity of the housing 10 and is capable of reciprocating in the longitudinal direction, with the sliding rack 20 located directly below the clearance groove 11.

[0057] There are two arc-shaped grippers 30, which are arranged on the lateral sides of the sliding rack 20, and one end of the arc-shaped gripper 30 is rotatably connected to the housing 10 through the rotating shaft 40.

[0058] There are two transmission gears 50, which are located on the lateral sides of the sliding rack 20. The two transmission gears 50 are coaxially and fixedly connected to the two rotating shafts 40. The transmission gears 50 are meshed with the sliding rack 20 for transmission.

[0059] The water inlet pipe 60 is located inside the arc-shaped gripper 30, and one end of the water inlet pipe 60 extends to the outside of the housing 10.

[0060] The adjustment handle 70 is located above the housing 10. The bottom end of the adjustment handle 70 passes through the clearance groove 11 and is fixedly connected to the sliding rack 20, so that the sliding rack 20 can be moved by the adjustment handle 70 and the two arc-shaped grippers 30 can move away from or closer to each other.

[0061] This invention utilizes a gear and rack transmission method. By adjusting the handle 70, the sliding rack 20 is driven to rotate the connection ends of the two arc-shaped grippers 30 and the housing 10, so that the other ends of the two arc-shaped grippers 30 can move away from or close to each other. This allows the water-saving irrigation device to be clamped and fixed on tree trunks of different diameters, thus improving the applicability of the water-saving irrigation device.

[0062] It should be noted that the longitudinal direction in this invention refers to... Figure 1 In the single-head direction, the lateral direction in this invention refers to... Figure 1 The direction of the double arrow in the image.

[0063] Specific embodiment 1, such as Figures 1-12 As shown, a water-saving irrigation device suitable for sparse woodland includes: a housing 10, a sliding rack 20, an arc-shaped gripper 30, a transmission gear 50, a water inlet pipe 60, and an adjusting handle 70.

[0064] The interior of the housing 10 is hollow, and a clearance groove 11 is formed on the top of the housing 10 along the longitudinal direction, which communicates with the inner cavity of the housing 10.

[0065] like Figure 3 As shown, in an optional embodiment, the clearance groove 11 is a strip-shaped oval hole, which is opened on the top plate of the housing 10 along one diameter of the housing 10 to facilitate the adjustment handle 70 to move in the longitudinal direction.

[0066] The sliding rack 20 is installed in the inner cavity of the housing 10 along the longitudinal direction, and the sliding rack 20 can reciprocate along the longitudinal direction; the sliding rack 20 is located directly below the clearance groove 11, and the clearance groove 11 is opened on the top plate of the housing 10 along the length direction of the sliding rack 20, that is, the moving direction of the sliding rack 20 is parallel to the length direction of the clearance groove 11.

[0067] like Figure 3 As shown, in an optional embodiment, two guide rods 12 are installed in parallel within the inner cavity of the housing 10. The two guide rods 12 are arranged in parallel along the longitudinal direction on both sides below the clearance groove 11. The longitudinal ends of the guide rods 12 are fixedly connected to the housing 10, and the middle part of the guide rods 12 passes through the guide hole on the sliding rack 20, so that the lateral ends of the sliding rack 20 are slidably connected to the two guide rods 12 along the longitudinal direction. This allows the sliding rack 20 to reciprocate along the longitudinal direction within the inner cavity of the housing 10, so that the guide rods 12 can limit and guide the movement of the sliding rack 20, further improving the stability of the sliding rack 20 during movement.

[0068] like Figure 4 and Figure 5 As shown, there are two arc-shaped grippers 30, which are arranged one-to-one on the lateral sides of the sliding rack 20, that is, the two arc-shaped grippers 30 are arranged one-to-one on the lateral sides of the housing 10. Opening slots are provided on both lateral sides of the housing 10, which are connected to the inner cavity of the housing 10. Two rotating shafts 40 are installed in the inner cavity of the housing 10. The two rotating shafts 40 are located one-to-one on the lateral sides of the sliding rack 20, and the top end of the rotating shaft 40 is rotatably connected to the top plate of the housing 10 through a bearing, and the bottom end of the rotating shaft 40 is rotatably connected to the bottom plate of the housing 10 through a bearing.

[0069] Two arc-shaped grippers 30 are arranged with their openings facing each other, and one end of each arc-shaped gripper 30 extends through the opening slot into the inner cavity of the housing 10 and is fixedly connected to the rotating shaft 40, so that the arc-shaped grippers 30 and the housing 10 can rotate relative to each other, thereby allowing the two arc-shaped grippers 30 to move away from each other or closer to each other, which is convenient for surrounding the water-saving irrigation device around the tree trunk and for clamping and fixing it to tree trunks of different diameters.

[0070] like Figure 2 As shown, there are two transmission gears 50, which are installed in the inner cavity of the housing 10 and are coaxially fixedly connected to the two rotating shafts 40 in a one-to-one correspondence. Teeth are provided on both sides of the sliding rack 20. The two transmission gears 50 are located on the two sides of the sliding rack 20 in a one-to-one correspondence, and the tooth grooves of the two transmission gears 50 are meshed with the teeth of the sliding rack 20 for transmission connection. The longitudinal movement of the sliding rack 20 drives the two transmission gears 50 to drive the rotating shafts 40 to rotate forward and backward, thereby causing the two arc-shaped grippers 30 to move away from or closer to each other.

[0071] like Figure 6 As shown, an arc-shaped inner cavity is provided inside the arc-shaped gripper 30, which extends along the arc length direction of the arc-shaped gripper 30; there are two water inlet pipes 60, and the two water inlet pipes 60 are installed in the arc-shaped inner cavities of the two arc-shaped grippers 30 in a one-to-one correspondence; one end of the water inlet pipe 60 extends to the outside of the housing 10 for connecting to an external water source.

[0072] It should be noted that: the water inlet pipe 60 has a connecting hole that connects the inner cavity of the water inlet pipe 60 and the arc-shaped inner cavity of the arc-shaped clamp 30, so that the irrigation water in the water inlet pipe 60 flows into the arc-shaped inner cavity of the arc-shaped clamp 30; drip irrigation holes are provided on the arc-shaped clamp 30, and multiple drip irrigation holes are evenly distributed along the arc length of the arc-shaped clamp 30, and the drip irrigation holes are connected to the arc-shaped inner cavity of the arc-shaped clamp 30 for drip irrigation of the plants.

[0073] like Figure 3 and Figure 7 As shown, the adjustment handle 70 is mounted on the top of the housing 10. The bottom end of the adjustment handle 70 passes through the clearance groove 11 and is fixedly connected to the sliding rack 20, so that the sliding rack 20 can be moved by the adjustment handle 70 and the two arc-shaped grippers 30 can move away from or closer to each other.

[0074] Specific embodiment 2, such as Figures 1-12 As shown, a water-saving irrigation device suitable for sparse woodland includes: a housing 10, a sliding rack 20, an arc-shaped gripper 30, a transmission gear 50, a water inlet pipe 60, and an adjusting handle 70.

[0075] like Figure 2 and Figure 3 As shown, a clearance groove 11 is formed on the top of the housing 10 along the longitudinal direction, and the clearance groove 11 communicates with the inner cavity of the housing 10.

[0076] like Figure 2 and Figure 3 As shown, the sliding rack 20 is installed in the inner cavity of the housing 10 along the longitudinal direction. The sliding rack 20 is located directly below the clearance groove 11, and the sliding rack 20 can reciprocate along the longitudinal direction.

[0077] like Figure 4 and Figure 5 As shown, there are two arc-shaped grippers 30, which are arranged one-to-one on the lateral sides of the sliding rack 20, that is, the two arc-shaped grippers 30 are arranged one-to-one on the lateral sides of the housing 10. Opening slots are provided on both lateral sides of the housing 10, which are connected to the inner cavity of the housing 10. Two rotating shafts 40 are installed in the inner cavity of the housing 10, which are located one-to-one on the lateral sides of the sliding rack 20, and the vertical ends of the rotating shafts 40 are rotatably connected to the housing 10 through bearings.

[0078] like Figure 2 and Figure 7 As shown, there are two transmission gears 50. The two transmission gears 50 are installed in the inner cavity of the housing 10. The two transmission gears 50 are coaxially and fixedly connected to the two rotating shafts 40 in a one-to-one correspondence. The two transmission gears 50 are meshed with the sliding rack 20 for transmission. The longitudinal movement of the sliding rack 20 drives the two transmission gears 50 to drive the rotating shafts 40 to rotate forward and backward, thereby causing the two arc-shaped grippers 30 to move away from or closer to each other.

[0079] like Figure 6 As shown, an arc-shaped inner cavity is provided inside the arc-shaped gripper 30, which extends along the arc length direction of the arc-shaped gripper 30; there are two water inlet pipes 60, and the two water inlet pipes 60 are installed in the arc-shaped inner cavities of the two arc-shaped grippers 30 in a one-to-one correspondence; one end of the water inlet pipe 60 extends to the outside of the housing 10 for connecting to an external water source.

[0080] like Figure 4 and Figure 5 As shown, the arc-shaped gripper 30 includes a fixed gripper segment 31, a telescopic gripper segment 32, a compression spring 33, a traction rope 34, and a traction wheel 35. The fixed gripper segment 31 and the telescopic gripper segment 32 have the same radial dimension, and both the fixed gripper segment 31 and the telescopic gripper segment 32 are provided with arc-shaped inner cavities. One end of the telescopic gripper segment 32 is sealed and slidably connected to the arc-shaped inner cavity of the fixed gripper segment 31.

[0081] The compression spring 33 is installed in the arc-shaped inner cavity of the fixed claw segment 31, and one end of the compression spring 33 is fixedly connected to the fixed claw segment 31, while the other end of the compression spring 33 is fixedly connected to the telescopic claw segment 32. The telescopic claw segment 32 extends out of the arc-shaped inner cavity of the fixed claw segment 31 through the elastic force of the compression spring 33, thereby increasing the arc length of the arc-shaped gripper 30.

[0082] like Figure 4 , Figure 5 and Figure 7As shown, two traction wheels 35 and two traction ropes 34 are installed in the inner cavity of the housing 10. The two traction wheels 35 are coaxially fixedly installed on the rotating shaft 40 in a one-to-one correspondence. One end of the traction rope 34 is fixedly connected to the telescopic claw section 32, and the other end of the traction rope 34 is wound around the traction wheel 35 so that when the rotating shaft 40 rotates, it can drive the traction wheel 35 to rotate synchronously, and make the length of the traction rope 34 wound on the traction wheel 35 longer or shorter. Thus, the telescopic claw section 32 extends out from the arc-shaped inner cavity of the fixed claw section 31 under the action of the compression spring 33, or the telescopic claw section 32 enters the arc-shaped inner cavity of the fixed claw section 31 under the action of the traction rope 34, so as to realize the adjustment of the arc length of the arc-shaped claw 30.

[0083] like Figure 5 As shown, in an optional embodiment, when the two arc-shaped grippers 30 move away from each other, the circumferential length of the arc-shaped grippers 30 gradually decreases; when the two arc-shaped grippers 30 move closer to each other, the circumferential length of the arc-shaped grippers 30 gradually increases. That is, the rotation direction of the two arc-shaped grippers 30 when they are open is opposite to the winding direction of the traction rope 34 on the traction wheel 35. For the traction wheel 35 located on the left side of the sliding rack 20, the traction rope 34 is wound clockwise on the traction wheel 35; for the traction wheel 35 located on the right side of the sliding rack 20, the traction rope 34 is wound counterclockwise on the traction wheel 35.

[0084] It should be noted that the water inlet pipe 60 is a telescopic water pipe. One half of the telescopic water pipe is installed in the arc-shaped inner cavity of the telescopic claw section 32, and the other half is installed in the arc-shaped inner cavity of the fixed claw section 31. A connecting hole is provided on the water inlet pipe 60, which connects the inner cavity of the water inlet pipe 60 with the arc-shaped inner cavity of the fixed claw section 31 or the telescopic claw section 32, so that the irrigation water in the water inlet pipe 60 flows into the arc-shaped inner cavity of the fixed claw section 31 or the telescopic claw section 32. Drip irrigation holes are provided on both the fixed claw section 31 and the telescopic claw section 32. Multiple drip irrigation holes are evenly distributed along the arc length direction of the arc-shaped claw 30, and the drip irrigation holes are connected to the arc-shaped inner cavity of the fixed claw section 31 or the telescopic claw section 32 for drip irrigation of the plants.

[0085] In an optional embodiment, a receiving groove is provided on the outer circumferential surface of the traction wheel 35, and the traction rope 34 is wound in the receiving groove. By providing a receiving groove for winding the traction rope 34, the situation where the traction rope 34 comes off the traction wheel 35 can be prevented.

[0086] like Figure 3 and Figure 7 As shown, the adjustment handle 70 is mounted on the top of the housing 10. The bottom end of the adjustment handle 70 passes through the clearance groove 11 and is fixedly connected to the sliding rack 20, so that the sliding rack 20 can be moved by the adjustment handle 70 and the two arc-shaped grippers 30 can move away from or closer to each other.

[0087] Specific embodiment 3, such as Figures 1-12 As shown, a water-saving irrigation device suitable for sparse woodland includes: a housing 10, a sliding rack 20, an arc-shaped gripper 30, a transmission gear 50, a water inlet pipe 60, and an adjusting handle 70.

[0088] like Figure 2 and Figure 3 As shown, a clearance groove 11 is formed on the top of the housing 10 along the longitudinal direction, and the clearance groove 11 communicates with the inner cavity of the housing 10.

[0089] like Figure 2 and Figure 3 As shown, the sliding rack 20 is installed in the inner cavity of the housing 10 along the longitudinal direction. The sliding rack 20 is located directly below the clearance groove 11, and the sliding rack 20 can reciprocate along the longitudinal direction.

[0090] like Figure 4 and Figure 5 As shown, there are two arc-shaped grippers 30, which are arranged one-to-one on both sides of the sliding rack 20. In other words, the two arc-shaped grippers 30 are arranged one-to-one on both sides of the sliding rack 20. Opening slots are provided on both sides of the housing 10, which are connected to the inner cavity of the housing 10. Two rotating shafts 40 are installed in the inner cavity of the housing 10. The two rotating shafts 40 are located one-to-one on both sides of the sliding rack 20, and the vertical ends of the rotating shafts 40 are rotatably connected to the housing 10 through bearings.

[0091] like Figure 2 and Figure 7 As shown, there are two transmission gears 50. The two transmission gears 50 are installed in the inner cavity of the housing 10. The two transmission gears 50 are coaxially and fixedly connected to the two rotating shafts 40 in a one-to-one correspondence. The two transmission gears 50 are meshed with the sliding rack 20 for transmission. The longitudinal movement of the sliding rack 20 drives the two transmission gears 50 to drive the rotating shafts 40 to rotate forward and backward, thereby causing the two arc-shaped grippers 30 to move away from or closer to each other.

[0092] like Figure 6 As shown, an arc-shaped inner cavity is provided inside the arc-shaped gripper 30, which extends along the arc length direction of the arc-shaped gripper 30; there are two water inlet pipes 60, and the two water inlet pipes 60 are installed in the arc-shaped inner cavities of the two arc-shaped grippers 30 in a one-to-one correspondence; one end of the water inlet pipe 60 extends to the outside of the housing 10 for connecting to an external water source.

[0093] like Figure 4 and Figure 5As shown, the arc-shaped gripper 30 includes a fixed gripper segment 31, a telescopic gripper segment 32, a compression spring 33, a traction rope 34, and a traction wheel 35. The fixed gripper segment 31 and the telescopic gripper segment 32 have the same radial dimension, and both the fixed gripper segment 31 and the telescopic gripper segment 32 are provided with arc-shaped inner cavities. One end of the telescopic gripper segment 32 is sealed and slidably connected to the arc-shaped inner cavity of the fixed gripper segment 31.

[0094] A fixing plate 37 is fixedly installed in the arc-shaped inner cavity of the fixing claw segment 31. The compression spring 33 is installed in the arc-shaped inner cavity of the fixing claw segment 31, and one end of the compression spring 33 is fixedly connected to the fixing plate 37, and the other end of the compression spring 33 is fixedly connected to the telescopic claw segment 32. The telescopic claw segment 32 is extended from the arc-shaped inner cavity of the fixing claw segment 31 by the elastic force of the compression spring 33, thereby increasing the arc length of the arc-shaped gripper 30.

[0095] like Figure 4 , Figure 5 and Figure 7 As shown, two traction wheels 35 and two traction ropes 34 are installed in the inner cavity of the housing 10. The two traction wheels 35 are coaxially fixedly installed on the rotating shaft 40 in a one-to-one correspondence. One end of the traction rope 34 passes through the fixed plate 37 and is fixedly connected to the telescopic claw section 32. The other end of the traction rope 34 is wrapped around the traction wheel 35 so that when the rotating shaft 40 rotates, it can drive the traction wheel 35 to rotate synchronously, and make the length of the traction rope 34 wrapped around the traction wheel 35 longer or shorter. This allows the telescopic claw section 32 to extend out from the arc-shaped inner cavity of the fixed claw section 31 under the action of the compression spring 33, or to enter the arc-shaped inner cavity of the fixed claw section 31 under the action of the traction rope 34, so as to realize the adjustment of the arc length of the arc-shaped claw 30.

[0096] like Figure 4 As shown, in an optional embodiment, a tensioning wheel 36 that cooperates with the traction rope 34 is installed in the arc-shaped inner cavity of the fixed claw segment 31. This tensioning wheel 36 is used to tension the traction rope 34. By setting the tensioning wheel 36, the traction rope 34 is kept taut, preventing the traction rope 34 from becoming loose and causing the telescopic claw segment 32 to extend out of the fixed claw segment 31 under the drive of the compression spring 33. At the same time, by keeping the traction rope 34 taut, the telescopic claw segment 32 can be retracted through the traction rope 34 as soon as the traction wheel 35 rotates, thus improving the overall action efficiency.

[0097] like Figure 3 and Figure 7 As shown, the adjustment handle 70 is mounted on the top of the housing 10. The bottom end of the adjustment handle 70 passes through the clearance groove 11 and is fixedly connected to the sliding rack 20, so that the sliding rack 20 can be moved by the adjustment handle 70 and the two arc-shaped grippers 30 can move away from or closer to each other.

[0098] like Figure 7 and Figure 12As shown, in an optional embodiment, a threaded through hole 21 is provided in the middle of the sliding rack 20, and the threaded through hole 21 extends through the sliding rack 20 in the vertical direction; the adjusting handle 70 includes a gripping part 71 and a screw part 72, the middle part of the screw part 72 is threadedly connected to the threaded through hole 21, the top end of the screw part 72 is vertically fixedly connected to the gripping part 71, and the bottom end of the screw part 72 is connected to the locking assembly 80, which is installed below the sliding rack 20 and can lock the longitudinal position of the sliding rack 20.

[0099] like Figure 7 and Figure 8 As shown, in an optional embodiment, the locking assembly 80 includes an upper locking plate 81, a limiting rod 82, and a lower locking plate 83. The upper locking plate 81 is located directly below the screw portion 72, and the top of the upper locking plate 81 is rotatably connected to the bottom end of the screw portion 72. There are two limiting rods 82, and the two limiting rods 82 are located on the longitudinal sides of the screw portion 72 respectively. The top end of the limiting rod 82 is vertically fixedly connected to the sliding rack 20, and the bottom end of the limiting rod 82 extends axially and passes through the upper locking plate 81, so that when the screw portion 72 rotates, the upper locking plate 81 can rise and fall synchronously with the screw portion 72, and the upper locking plate 81 does not rotate.

[0100] like Figure 8 As shown, the lower locking plate 83 is located directly below the upper locking plate 81, extending longitudinally and fixedly connected to the housing 10. An upper engaging portion 811 is provided on the upper locking plate 81, meaning that multiple upper limit bars are fixedly installed on the lower end face of the upper locking plate 81, and these upper limit bars are linearly distributed longitudinally. A lower engaging portion 831 is provided on the upper end face of the lower locking plate 83, meaning that multiple lower limit bars are fixedly installed on the upper end face of the lower locking plate 83, and these lower limit bars are linearly distributed longitudinally. During the descent of the upper locking plate 81, when the upper engaging portion 811 of the upper locking plate 81 and the lower engaging portion 831 of the lower locking plate 83 engage with each other, the position of the sliding rack 20 can be locked.

[0101] It should be noted that: when there are two lower locking plates 83, the two lower locking plates 83 are spaced laterally to form a gap between the two lower locking plates 83 to avoid the limiting rod 82; when there is only one lower locking plate 83, a long slot is provided on the lower locking plate 83 to avoid the limiting rod 82.

[0102] Specific embodiment 4, such as Figures 1-12 As shown, a water-saving irrigation device suitable for sparse woodland includes: a housing 10, a sliding rack 20, an arc-shaped gripper 30, a transmission gear 50, a water inlet pipe 60, and an adjusting handle 70.

[0103] like Figure 2 and Figure 3 As shown, a clearance groove 11 is formed on the top of the housing 10 along the longitudinal direction, and the clearance groove 11 communicates with the inner cavity of the housing 10.

[0104] like Figure 2 and Figure 3 As shown, the sliding rack 20 is installed in the inner cavity of the housing 10 along the longitudinal direction. The sliding rack 20 is located directly below the clearance groove 11, and the sliding rack 20 can reciprocate along the longitudinal direction.

[0105] like Figure 4 and Figure 5 As shown, there are two arc-shaped grippers 30, which are arranged one-to-one on both sides of the sliding rack 20. In other words, the two arc-shaped grippers 30 are arranged one-to-one on both sides of the sliding rack 20. Opening slots are provided on both sides of the housing 10, which are connected to the inner cavity of the housing 10. Two rotating shafts 40 are installed in the inner cavity of the housing 10. The two rotating shafts 40 are located one-to-one on both sides of the sliding rack 20, and the vertical ends of the rotating shafts 40 are rotatably connected to the housing 10 through bearings.

[0106] like Figure 2 and Figure 7 As shown, there are two transmission gears 50. The two transmission gears 50 are installed in the inner cavity of the housing 10. The two transmission gears 50 are coaxially and fixedly connected to the two rotating shafts 40 in a one-to-one correspondence. The two transmission gears 50 are meshed with the sliding rack 20 for transmission. The longitudinal movement of the sliding rack 20 drives the two transmission gears 50 to drive the rotating shafts 40 to rotate forward and backward, thereby causing the two arc-shaped grippers 30 to move away from or closer to each other.

[0107] like Figure 6 As shown, an arc-shaped inner cavity is provided inside the arc-shaped gripper 30, which extends along the arc length direction of the arc-shaped gripper 30; there are two water inlet pipes 60, and the two water inlet pipes 60 are installed in the arc-shaped inner cavities of the two arc-shaped grippers 30 in a one-to-one correspondence; one end of the water inlet pipe 60 extends to the outside of the housing 10 for connecting to an external water source.

[0108] like Figure 3 and Figure 7 As shown, the adjustment handle 70 is mounted on the top of the housing 10. The bottom end of the adjustment handle 70 passes through the clearance groove 11 and is fixedly connected to the sliding rack 20, so that the sliding rack 20 can be moved by the adjustment handle 70 and the two arc-shaped grippers 30 can move away from or closer to each other.

[0109] like Figure 7 and Figure 12As shown, a threaded through hole 21 is provided in the middle of the sliding rack 20, and the threaded through hole 21 extends through the sliding rack 20 in the vertical direction; the adjusting handle 70 includes a grip part 71 and a screw part 72. The grip part 71 is located directly above the housing 10. The middle part of the screw part 72 is threaded into the threaded through hole 21. The top end of the screw part 72 is vertically fixedly connected to the grip part 71. The bottom end of the screw part 72 is connected to the locking assembly 80. The locking assembly 80 is installed below the sliding rack 20 and can lock the longitudinal position of the sliding rack 20.

[0110] like Figure 7 , Figures 9-11 As shown, the locking assembly 80 includes an upper locking plate 81, a lower locking plate 83, a fixing bracket 84, and a return spring 85; the upper locking plate 81 is located directly below the screw portion 72, and the upper locking plate 81 is rotatably connected to the bottom end of the screw portion 72.

[0111] Specifically, the upper locking plate 81 is sleeved on the bottom end of the screw part 72. The inner side of the upper locking plate 81 is provided with an annular groove, and the bottom end of the screw part 72 is provided with an annular protrusion. The rotation of the adjusting handle 70 will not drive the upper locking plate 81 to rotate. At the same time, the vertical displacement of the adjusting handle 70 will drive the upper locking plate 81 to move up and down.

[0112] There are two fixing brackets 84, which are located on opposite sides below the upper locking plate 81 and extend longitudinally and are fixedly connected to the housing 10. Each fixing bracket 84 has a mounting slot on its opposite side. There are two lower locking plates 83, which extend longitudinally and are housed in the mounting slots of the two fixing brackets 84. The return spring 85 is installed in the mounting slot, with one end connected to the fixing bracket 84 and the other end fixedly connected to the lower locking plate 83, so that the lower locking plate 83 can extend out of the mounting slot under the elastic force of the return spring 85.

[0113] like Figure 10 As shown, upper pressing slopes 812 are provided on both sides of the bottom of the upper locking plate 81, and a lower pressing slope 832 that cooperates with the upper pressing slopes 812 is provided on the top of the lower locking plate 83 near the upper locking plate 81. This allows the upper pressing slopes 812 and the lower pressing slopes 832 to fit tightly together during the descent of the upper locking plate 81, thereby driving the lower locking plate 83 to move laterally and enter the mounting slot of the fixing frame 84.

[0114] Upper locking ramps 813 are provided on both sides of the top of the upper locking plate 81. Upper engaging parts 811 are provided on the upper locking ramps 813. In other words, multiple upper limit bars are fixedly installed on the upper locking ramps 813, and the multiple upper limit bars are linearly distributed along the longitudinal direction.

[0115] A lower locking slope 833 is provided at the bottom of the lower locking plate 83 near the upper locking plate 81. A lower engaging part 831 is provided on the lower locking slope 833. In other words, multiple lower limit bars are fixedly installed on the lower locking slope 833, and the multiple lower limit bars are linearly distributed along the longitudinal direction.

[0116] When the upper locking plate 81 moves synchronously with the screw part 72 to below the lower locking plate 83, under the elastic force of the return spring 85, the two lower locking plates 83 extend out from the fixing frame 84 and approach each other. After the lower engaging part 831 of the lower locking plate 83 engages with the upper engaging part 811 of the upper locking plate 81, the longitudinal position of the sliding rack 20 can be locked.

[0117] An embodiment provides a water-saving irrigation method suitable for sparse woodlands. This method utilizes the aforementioned water-saving irrigation device for sparse woodlands and includes the following steps:

[0118] S1: Push the adjusting handle 70 in the longitudinal direction to make the two arc-shaped jaws 30 open outward until the adjusting handle 70 can no longer be pushed.

[0119] S2: Move the two arc-shaped claws 30 to the sides of the tree trunk, that is, make the fixed claw segment 31 and the telescopic claw segment 32 wrap around the tree trunk.

[0120] S3: Push the adjustment handle 70 in the opposite direction to make the two arc-shaped clamps 30 retract inward until the two arc-shaped clamps 30 clamp the tree trunk.

[0121] S4: Connect the inlet pipe 60 to an external water source.

[0122] In one specific embodiment, step S3 specifically includes the following steps:

[0123] S31: Push the adjusting handle 70 longitudinally to make the two arc-shaped clamps 30 retract inward until the two arc-shaped clamps 30 clamp the tree trunk.

[0124] S32: Rotate the adjusting handle 70 so that the adjusting handle 70 moves downward along the threaded through hole 21 of the sliding rack 20 until the locking component 80 at the bottom of the adjusting handle 70 locks the longitudinal position of the sliding rack 20.

[0125] The working process of the water-saving irrigation device of the present invention is as follows:

[0126] When the sliding rack 20 moves longitudinally under the drive of the adjusting handle 70, the sliding rack 20 drives the two transmission gears 50 to rotate in opposite directions. The two transmission gears 50 simultaneously drive the two rotating shafts 40 to rotate in opposite directions, thereby causing the two arc-shaped grippers 30 to move away from each other and unfold. At this time, the traction wheel 35 winds up the traction rope 34 and drives the two telescopic claw sections 32 to retract into the fixed claw section 31, further increasing the opening size of the two arc-shaped grippers 30, so that the water-saving irrigation device can wrap around the circumference of tree trunks of different diameters, allowing the water-saving irrigation device to stably grip thicker tree trunks.

[0127] After the housing 10 surrounds the trunk, push the adjusting handle 70 in the opposite direction to make the two arc-shaped grippers 30 close together. At this time, the traction wheel 35 releases the traction rope 34 and drives the two telescopic claw sections 32 to extend. After the telescopic claw section 32 and the fixed claw section 31 clamp the trunk, the water inlet pipe 60 can be connected to an external water source and water can be supplied intermittently through the control circuit, so as to intermittently irrigate the root system of the trunk and achieve the purpose of saving water.

[0128] When the longitudinal position of the sliding rack 20 needs to be locked, rotate the grip 71 of the adjusting handle 70. The screw 72 of the adjusting handle 70 moves downward along the threaded through hole 21 of the sliding rack 20. At this time, the upper locking plate 81 at the bottom of the adjusting handle 70 contacts the lower locking plate 83, causing the lower locking plate 83 to move into the mounting groove of the fixing bracket 84 and press the return spring 85. When the upper locking plate 81 descends below the lower locking plate 83, the lower locking plate 83 moves laterally under the elastic force of the return spring 85. When the device is moved and returned to its original position, the lower engagement portion 831 at the bottom of the lower locking plate 83 engages with the upper engagement portion 811 at the top of the upper locking plate 81, thereby locking the position of the sliding rack 20 in the longitudinal direction. This prevents the adjusting handle 70 from moving, thus avoiding the situation where animals in the forest move the adjusting handle 70 and cause the arc-shaped gripper 30 to loosen from the tree trunk. On the other hand, since the sliding rack 20 and the transmission gear 50 are not disengaged, the arc-shaped gripper 30 can still maintain the state of clamping the tree trunk.

[0129] When it is necessary to loosen the trunk, rotate the adjusting handle 70 in the opposite direction, so that the screw part 72 of the adjusting handle 70 moves upward along the threaded through hole 21. At this time, the upper locking plate 81 presses the lower locking plate 83 laterally, and moves the lower locking plate 83 into the mounting groove of the fixing frame 84 and presses the return spring 85. When the upper locking plate 81 rises above the lower locking plate 83, the longitudinal locking of the sliding rack 20 is released, so that the adjusting handle 70 returns to a state where it can move normally, so that pushing the adjusting handle 70 can release the arc-shaped clamp 30. At the same time, the lower locking plate 83 moves laterally under the elastic force of the return spring 85 and returns to its original position.

[0130] Compared with the prior art, this application has at least the following beneficial technical effects:

[0131] The water-saving irrigation device of the present invention uses adjustable arc-shaped clamps to keep the tree trunk in a clamping state, so that the water-saving irrigation device can be placed on tree trunks of different diameters, thereby improving the applicability of the water-saving irrigation device.

[0132] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
