Description

Technical Field

[0001] This utility model relates to the field of dwarfing and dense planting technology for sweet cherries, specifically a water-saving drip irrigation device for dwarfing and dense planting of sweet cherries. Background Technology

[0002] The definition of dwarfing and high-density planting of sweet cherries refers to the use of dwarfing rootstocks and techniques to limit root expansion, thereby dwarfing cherry trees and increasing planting density per unit area to achieve the goals of early fruiting, early high yield, easy management, and more high-quality fruit.

[0003] The advantages of dwarfing and dense planting of sweet cherries include improved economic benefits, shorter cost recovery period, increased yield per tree and per acre, and easier management and harvesting. Densely planted fruit trees require the use of water-saving drip irrigation devices to individually drip irrigate each tree to ensure uniform and excellent overall growth and increase fruit tree yield. However, when using existing water-saving drip irrigation devices, the position of the drip holes on the drip irrigation pipes is fixed, while the spacing between densely planted sweet cherry trees is different. Some drip holes cannot reach the sweet cherry trees, affecting the growth of some fruit trees. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-saving drip irrigation device for dwarfing and dense planting of sweet cherries, comprising a water storage tank and a water pump. A water delivery pipe is provided on the surface of the water pump, and a drip irrigation pipe is provided on the surface of the water delivery pipe.

A limiting connector is fixedly connected to the surface of the drip irrigation pipe, and a connecting shaft is fixedly connected to the surface of the limiting connector. An eccentric wheel is rotatably connected to the surface of the connecting shaft, and a first adjusting handle is fixedly connected to the surface of the eccentric wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By connecting the extension tube to the drip irrigation pipe, the extension tube can be extended to extend the effective length of the drip irrigation pipe. Then, through the connection of the limiting connector and the connecting shaft, and the connection of the eccentric wheel and the first adjusting handle, rotating the first adjusting handle causes the eccentric wheel to rotate. Through the connection of the eccentric wheel and the abutment block, and the connection of the locking block and the locking groove, the abutment block can drive the locking block to abut against the surface of the locking groove, forming a friction self-locking, fixing the position of the extension tube. The damping spring follows the deformation. Then, through the connection of the locking block and the damping spring, and the connection of the locking block and the guide rod, the first adjusting handle is reset. The damping spring can drive the locking block to reset in order to return to its original state. The guide rod provides guidance for the movement of the locking block, thus achieving the effect of adjusting the effective length of the drip irrigation pipe.

[0014] By connecting the second adjusting handle to the worm gear and the connecting plate to the worm wheel, the second adjusting handle can be rotated to drive the worm gear to rotate, causing the worm wheel to rotate synchronously. Then, by connecting the worm wheel to the clockwise threaded rod and the limiting connecting rod to the counterclockwise threaded rod, the clockwise and counterclockwise threaded rods can rotate synchronously with the worm wheel. Furthermore, by connecting the clockwise threaded rod to the first clamping plate and the counterclockwise threaded rod to the second clamping plate, the first and second clamping plates can move towards each other, thereby clamping the cherry tree and ensuring that the drip irrigation pipe's drip holes act next to the cherry tree, thus improving the cherry tree's growth.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 One embodiment provided by this utility model:

[0023] A water-saving drip irrigation device for dwarfing and dense planting of sweet cherries includes a water storage tank 1 and a water pump 11. A water delivery pipe 12 is provided on the surface of the water pump 11, and a drip irrigation pipe 13 is provided on the surface of the water delivery pipe 12. The water storage tank 1, water pump 11, water delivery pipe 12, and drip irrigation pipe 13 are all existing products and are not considered technical protection points of this application; therefore, they will not be described in detail here. An extension pipe 2 is movably connected to the surface of the drip irrigation pipe 13 to extend its length. A groove 21 is provided on the surface of the extension pipe 2 for frictional self-locking with a locking block 26. A limit connector 22 is fixedly connected to the surface of the drip irrigation pipe 13 for... A connecting shaft 23 is fixedly connected to the surface of the limiting connector 22, which is used to rotate the eccentric wheel 24. The surface of the connecting shaft 23 is rotatably connected to the eccentric wheel 24, which abuts against the surface of the abutment block 27. A first adjusting handle 25 is fixedly connected to the surface of the eccentric wheel 24, which drives the eccentric wheel 24 to rotate. A locking block 26 is movably connected to the surface of the limiting connector 22, which is used for friction self-locking with the locking groove 21. The surface of the locking block 26 is fixedly connected to the abutment block 27, which drives the locking block 26 to move. A guide rod 28 is fixedly connected inside the limiting connector 22, which provides guidance for the movement of the locking block 26. A damping spring 29 is wound around the surface of the drip irrigation pipe 13 to reset the locking block 26. A connecting plate 3 is fixedly connected to the surface of the drip irrigation pipe 13 to connect a clockwise threaded rod 34 and a counterclockwise threaded rod 36. A second adjusting handle 31 is rotatably connected to the surface of the connecting plate 3 to drive the worm gear 32 to rotate. A worm gear 32 is fixedly connected to the surface of the second adjusting handle 31 to drive the worm wheel 33 to rotate. A worm wheel 33 is meshed with the surface of the worm gear 32 to drive the clockwise threaded rod 34 and the counterclockwise threaded rod 36 to rotate. A clockwise threaded rod 34 is fixedly connected to the surface of the worm wheel 33 to move the first clamping plate 37. A limiting connecting rod 35 is fixedly connected to one end of the clockwise threaded rod 34 away from the worm gear 33. This rod connects the clockwise threaded rod 34 and the counterclockwise threaded rod 36, limiting the movement of the first clamping plate 37 and the second clamping plate 38. The counterclockwise threaded rod 36 is fixedly connected to one end of the limiting connecting rod 35 away from the clockwise threaded rod 34, which drives the second clamping plate 38 to move. The surface of the clockwise threaded rod 34 is threadedly fitted with the first clamping plate 37, which cooperates with the second clamping plate 38 to clamp the cherry tree. The surface of the counterclockwise threaded rod 36 is threadedly fitted with the second clamping plate 38, which cooperates with the first clamping plate 37 to clamp the cherry tree.

[0024] Furthermore, the drip irrigation pipes 13 are in multiple sets, and the multiple sets of drip irrigation pipes 13 are used to irrigate multiple cherry trees. The eccentric wheel 24 is rotatably connected to the surface of the connecting shaft 23 via the first adjusting handle 25. The eccentric wheel 24 is rotatably connected to the surface of the limiting connector 22 via the connecting shaft 23. Rotating the first adjusting handle 25 can drive the eccentric wheel 24 to rotate on the surface of the connecting shaft 23.

[0025] Furthermore, the abutment 27 is movably connected to the surface of the eccentric wheel 24 and the limiting connector 22, the locking block 26 is abutted to the surface of the abutment 27 and the locking groove 21, and the extension tube 2 is fixedly connected to the surface of the drip irrigation pipe 13 through the locking block 26. The eccentric wheel 24 rotates and abuts against the surface of the abutment 27, causing the abutment 27 to drive the locking block 26 to move downward, thereby causing the abutment 27 to self-lock against the locking groove 21 through friction, and fixing the extension position of the extension tube 2.

[0026] Furthermore, the guide rods 28 are symmetrically distributed in two sets at both ends of the locking block 26. The locking block 26 is movably connected to the surface of the limiting connector 22 through the guide rods 28. The locking block 26 moves on the surface of the guide rods 28, and the guide rods 28 provide guidance for the movement of the locking block 26.

[0027] Furthermore, the two ends of the damping spring 29 are fixedly connected to the inside of the limiting connector 22 and the surface of the locking block 26. The locking block 26 is movably connected to the surface of the guide rod 28 through the damping spring 29. The first adjusting handle 25 is turned back to its original position, so that the eccentric wheel 24 leaves the surface of the abutment block 27. The damping spring 29 drives the locking block 26 to reset and leave the surface of the slot 21 in order to restore its original state, thus canceling the fixation of the extension tube 2.

[0028] Furthermore, a fixed shaft is fixedly connected inside the connecting plate 3. The worm 32 is rotatably connected to the inside of the connecting plate 3 via the second adjusting handle 31. The worm wheel 33 is rotatably connected to the inside of the connecting plate 3 via the worm 32. Rotating the second adjusting handle 31 can drive the worm 32 to rotate, thereby driving the worm wheel 33 to rotate synchronously on the fixed shaft inside the connecting plate 3.

[0029] Furthermore, the clockwise threaded rod 34 is rotatably connected to the surface of the connecting plate 3 via the worm gear 33, the first clamping plate 37 is movably connected to the surface of the drip irrigation pipe 13 via the clockwise threaded rod 34, the counterclockwise threaded rod 36 is rotatably connected to the surface of the connecting plate 3 via the clockwise threaded rod 34, and the second clamping plate 38 is movably connected to the surface of the drip irrigation pipe 13 via the counterclockwise threaded rod 36. The rotation of the worm gear 33 drives the clockwise threaded rod 34 and the counterclockwise threaded rod 36 to rotate synchronously. The threaded grooves on the surfaces of the clockwise threaded rod 34 and the counterclockwise threaded rod 36 are opened in opposite directions, causing the first clamping plate 37 and the second clamping plate 38 to move towards each other, thereby clamping the cherry tree and preventing the drip irrigation pipe 13 from being too far away from the cherry tree.

[0030] Working principle: When using the water storage tank 1, the effective length of the drip irrigation pipe 13 is first adjusted according to the spacing of the cherry trees. By extending the extension tube 2, the effective length of the drip irrigation pipe 13 is extended. Then, the first adjusting handle 25 is rotated to drive the eccentric wheel 24 to rotate on the surface of the connecting shaft 23. The rotation of the eccentric wheel 24 abuts against the surface of the abutment block 27, causing the abutment block 27 to drive the locking block 26 downward. This causes the abutment block 27 to rub against the locking groove 21 and lock itself, fixing the extended position of the extension tube 2. The damping spring 29 deforms accordingly. If the effective length of the drip irrigation pipe 13 needs to be changed again, the first adjusting handle 25 can be turned back to its original position, causing the eccentric wheel 24 to disengage. On the surface of the opening block 27, the damping spring 29, in order to restore its original state, drives the locking block 26 to reset and leave the surface of the locking groove 21, thus canceling the fixation of the extension pipe 2. Then, in order to prevent the drip irrigation pipe 13 from being too far away from the cherry tree, the first clamping plate 37 and the second clamping plate 38 can be used to clamp the cherry tree. Then, rotating the second adjusting handle 31 can drive the worm gear 32 to rotate, so that the worm wheel 33 rotates synchronously. The rotation of the worm wheel 33 drives the clockwise threaded rod 34 and the counterclockwise threaded rod 36 to rotate synchronously. The thread grooves on the surfaces of the clockwise threaded rod 34 and the counterclockwise threaded rod 36 are opened in opposite directions, so that the first clamping plate 37 and the second clamping plate 38 move towards each other, thereby clamping the cherry tree.
