[0041] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0042] like Figure 1-6 As shown, the adjustable-angle garden sprinkler system includes a movable base 1; it also includes: a water tank 2, with a water inlet 201 on the top of the water tank 2; the water tank 2 is fixedly installed on the top of the movable base 1, and a filter water inlet mechanism 7 is provided inside the water tank 2; the filter water inlet mechanism 7 is provided with two filter screens 703, and two tamping parts 9 are provided inside the filter water inlet mechanism 7, which are used to unclog the two filter screens 703 respectively; a sprinkler head 4, with a U-shaped frame 3 provided above the movable base 1, and the sprinkler head 4 is rotatably connected to the U-shaped frame 3; a water conveying mechanism 5, with the inlet and outlet ends of the water conveying mechanism 5 connected to the filter water inlet mechanism 7 and the sprinkler head 4 respectively; a drive mechanism 6, which is connected to the sprinkler head 4, and is also connected to a transmission mechanism 8, which is connected to the two tamping parts 9, and the transmission mechanism 8 causes the two tamping parts 9 to move in opposite directions.

[0043] like Figure 1As shown, as a specific technical solution, a support frame 302 is fixedly installed at the bottom of the U-shaped frame 3, and the bottom end of the support frame 302 is fixedly connected to the top surface of the movable base 1. Side frames 301 are fixedly installed between the two sides of the support frame 302 and the top surface of the movable base 1. The support frame 302 and the side frames 301 provide support and fixation for the U-shaped frame 3.

[0044] like Figure 2 As shown, as a specific technical solution, the water conveying mechanism 5 includes a water pump 501; the water pump 501 is fixedly installed on the top of the water tank 2, the water inlet of the water pump 501 is connected to an inlet pipe 504, the water outlet of the water pump 501 is connected to an outlet pipe 502, and the outlet pipe 502 is connected to one end of the sprinkler head 4 through a spiral hose 503.

[0045] Water pump 501 draws water from water tank 2 through water inlet pipe 504. After the water is filtered by water inlet filter mechanism 7, it enters water pump 501 through water inlet pipe 504, and then enters sprinkler head 4 through water outlet pipe 502 and spiral hose 503. Water is sprayed through sprinkler head 4 to irrigate the plants in front.

[0046] like Figure 5-6 As shown, the water inlet filter mechanism 7 includes a housing 701. The top of the housing 701 is fixedly connected to the bottom of the water inlet pipe 504. An intermediate plate 702 is fixedly installed in the middle of the lower opening of the housing 701. Two filter screens 703 are respectively fixedly installed on both sides of the intermediate plate 702.

[0047] The two filter screens 703 and the intermediate plate 702 together block the opening at the bottom of the housing 701, so that the water entering the water inlet pipe 504 must be filtered by the filter screens 703. This prevents impurities from entering the water pump 501 through the water inlet pipe 504 and then entering the sprinkler head 4, causing the sprinkler head 4 to become clogged.

[0048] like Figure 2-3 As shown, as a specific technical solution, the drive mechanism 6 includes a motor 604 fixedly installed on the top surface of the water tank 2 and a first pulley 602. A second pulley 605 is fixedly sleeved on the output shaft of the motor 604. A rotating shaft 601 is fixedly installed in the middle of the first pulley 602. The rotating shaft 601 is rotatably connected to the U-shaped frame 3 and fixedly connected to the sprinkler head 4. A transmission belt 603 is wound between the first pulley 602 and the second pulley 605. The diameter of the first pulley 602 is three times the diameter of the second pulley 605.

[0049] Figure 2-3 In the middle, the sprinkler head 4 is in a horizontal state. The drive mechanism 6 drives the sprinkler head 4 to flip upward and downward to adjust the angle and meet the irrigation needs of a larger angle area in front of the sprinkler head 4.

[0050] Specifically, the driving mechanism 6 causes the sprinkler head 4 to rotate upwards by 60° and downwards by 60°, thereby achieving sprinkler irrigation within a 120° angle range.

[0051] The drive mechanism 6 operates as follows: Motor 604 first drives the second pulley 605 to rotate 180 degrees counterclockwise. Through the transmission belt 603, the first pulley 602 rotates 60 degrees counterclockwise. The first pulley 602 drives the sprinkler head 4 to rotate upward 60 degrees through the rotating shaft 601. Then, motor 604 drives the second pulley 605 to rotate 360 ​​degrees clockwise. Through the transmission belt 603, the first pulley 602 rotates 120 degrees clockwise. The first pulley 602 drives the sprinkler head 4 to rotate downward 120 degrees through the rotating shaft 601. After that, motor 604 reciprocates by driving the second pulley 605 to rotate 360 ​​degrees counterclockwise and 360 degrees clockwise, thereby enabling the sprinkler head 4 to reciprocate within a 120° angle range and achieve sprinkler irrigation within a 120° angle range.

[0052] like Figure 3-4 As shown, as a specific technical solution, the transmission mechanism 8 includes a cover 801 fixedly installed on the top surface of the water tank 2; two racks 807 are vertically slidably installed inside the cover 801, and a gear 808 is meshed between the two racks 807, and the gear 808 is rotatably installed inside the cover 801; a connecting rod 809 is fixedly connected to the bottom end of each of the two racks 807, and the connecting rod 809 passes through a first through hole opened on the top of the water tank 2; a movable strip 802 is fixedly connected to the top end of one of the racks 807, and the movable strip 802 passes through a side groove 8011 opened on one side of the cover 801, and the movable strip 802 extends to the outside of the cover 801; the movable strip 802 is elastically connected to the top surface of the water tank 2; a cam 806 abuts against the bottom of the movable strip 802, and the cam 806 is fixedly connected to the output shaft of the motor 604.

[0053] A guide sleeve 803 is fixedly installed on the movable strip 802, and a guide post 804 is fixedly connected to the top surface of the water tank 2. The guide sleeve 803 and the guide post 804 are connected with a clearance fit. A spring 805 is sleeved on the guide post 804, and the bottom surface of the guide sleeve 803 and the top surface of the water tank 2 are elastically connected by the spring 805.

[0054] While the motor 604 drives the second pulley 605 to rotate, enabling the sprinkler head to be adjusted at four angles, the cam 806 rotates 360°. The cam 806 pushes the movable bar 802 upwards, guided by the guide sleeve 803 and guide post 804. Simultaneously, it stretches the spring 805, causing the movable bar 802 to drive one rack 807 upwards. Through the transmission of the gear 808, the other rack 807 moves downwards, causing the two connecting rods 809 to drive the two tamping parts 9 upwards and downwards respectively. The cam 806 then resets, and the spring force of the spring 805 resets the movable bar 802. The movable bar 802 then drives one rack 807 downwards... As rack 807 moves downward, it is driven by gear 808 to move another rack 807 upward, thereby causing the two connecting rods 809 to drive the two tamping parts 9 to move downward and upward respectively. Through the above, the two tamping parts 9 can move vertically in opposite directions. Each time the tamping part 9 moves downward, it tamps and cleans the mesh of its corresponding filter screen 703, ensuring that the mesh of one filter screen 703 is cleaned each time (but it may be blocked by the tamping head 902), while the mesh of the other filter screen 703 is not cleaned and tamped (not blocked), thus achieving cleanability and ensuring that one filter screen 703 is unobstructed each time, without affecting the water entering the housing 701.

[0055] like Figure 6 As shown, the interior of the back of the housing 701 is in a state where one of the tamping parts 9 is in a low position, that is, it has moved downwards and the tamping head 902 passes through the mesh of the corresponding filter screen 703 to achieve cleaning and tamping; the other tamping part 9 is in a high position, that is, it has moved upwards and the tamping head 902 is not inserted into the mesh of the corresponding filter screen 703, and its mesh ensures unobstructed flow.

[0056] The tamping section 9 includes a movable plate 901, and a tamping head 902 for inserting into the mesh hole of the filter screen 703 is fixedly connected to the bottom of the movable plate 901.

[0057] The connecting rod 809 passes through the second through hole opened at the top of the housing 701, and the bottom end of the connecting rod 809 is fixedly connected to the movable plate 901.

[0058] A corrugated hose 10503 is sleeved on the connecting rod 809. The top end of the corrugated hose 10503 is fixedly sealed to the top end of the second through hole, and the top end of the corrugated hose 10503 is fixedly sleeved to the rod surface of the connecting rod 809.

[0059] The corrugated hose 10503 is used to seal the second through hole, and when the connecting rod 809 moves up and down, the corrugated hose 10503 extends and retracts, without affecting the up and down movement of the connecting rod 809.

[0060] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
