Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler equipment, in particular to a reel-type sprinkler for farmland water-saving irrigation. Background Art

[0002] A sprinkler is an irrigation machine that winds the traction PE pipe on a winch, uses the sprinkler pressure water to drive the water turbine to rotate, drives the winch to rotate through the speed change device, and pulls the sprinkler car to automatically move and spray. The reel sprinkler adopts a water turbine power drive system, adopts a large cross-section and low pressure design, and can achieve a high recovery speed at a very small flow rate. The water turbine speed is led from the water turbine shaft to a two-speed belt drive device and transmitted to the reducer. After the speed is reduced, the chain drive generates a large torque force to drive the winch to rotate, thereby realizing the automatic recovery of the PE pipe.

[0003] The reel-type sprinkler needs to recycle the PE pipe after the irrigation is completed. The existing PE pipe is often tangled when it is reeled back during irrigation, causing the machine to not work properly, and even causing equipment damage, and unable to irrigate normally, bringing unnecessary workload. In view of this, we need a reel-type sprinkler for farmland water-saving irrigation. Utility Model Content

[0011] Preferably, the adjustment mechanism comprises a connecting plate, the connecting plate is fixedly mounted on the outer wall of the supporting plate, and a mounting ring is fixedly mounted on the outer wall of the connecting plate.

[0012] Preferably, an adjusting screw rod passes through the interior of the mounting ring, an end of the adjusting screw rod is fixedly connected to the outer wall of the fixing plate, and an adjusting hand wheel is threadedly connected to the adjusting screw rod.

[0013] Preferably, a tension spring is sleeved on the outer wall of the adjusting screw rod, one end of the tension spring is in contact with the outer wall of the mounting ring, and the other end of the tension spring is in contact with the outer wall of the adjusting hand wheel.

[0014] Compared with the prior art, the utility model provides a reel-type sprinkler for water-saving irrigation of farmland, which has the following beneficial effects:

[0015] 1. The farmland water-saving irrigation reel sprinkler presses the brake belt against the outer wall of the brake disc through the fixed plate in the brake stop mechanism, which can slow down the speed of the main shaft driven by the brake disc, and slow down the speed of the winding wheel driven by the main shaft, so as to prevent the winding wheel from winding too fast and causing entanglement and disorder in the recovery of PE pipe.

[0016] 2. The farmland water-saving irrigation reel sprinkler can compress the tension spring by rotating the adjusting hand wheel in the adjusting mechanism. The elastic force of the tension spring pushes the adjusting hand wheel, so that the fixing plate can tighten the brake belt, making it convenient to adjust the rotation speed of the winding wheel.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a farmland water-saving irrigation reel-type sprinkler, comprising a base 1, a support plate 2 is fixedly installed on the base 1, a winding wheel 3 is rotatably connected to the outer wall of the support plate 2, the end of the winding wheel 3 is fixedly connected to the main shaft 4, a brake mechanism 5 is arranged on the outer wall of the main shaft 4, and an adjustment mechanism 6 is fixedly installed on the outer wall of the support plate 2.

[0023] In this embodiment, a brake mechanism 5 is provided on the outer wall of the main shaft 4. The brake belt 52 is pressed against the outer wall of the brake disc 51 through the fixed plate 53 in the brake mechanism 5, so that the brake disc 51 can drive the main shaft 4 to slow down, and the speed of the winding wheel 3 is slowed down by the main shaft 4, which can prevent the winding wheel 3 from winding up too fast, causing entanglement and disorder in the recovery of the PE pipe.

[0024] In this embodiment, an adjusting mechanism 6 is fixedly installed on the outer wall of the support plate 2. By rotating the adjusting hand wheel 64 in the adjusting mechanism 6, the tensioning spring 65 can be compressed. The elastic force of the tensioning spring 65 pushes the adjusting hand wheel 64, so that the fixing plate 53 can tighten the brake belt 52, thereby facilitating the adjustment of the rotation speed of the winding wheel 3.

[0025] The above-mentioned brake mechanism 5 includes a brake disc 51, which is fixedly mounted on the outer wall of the main shaft 4. A brake belt 52 is wound around the outer wall of the brake disc 51, and a fixing plate 53 is wound around the outer wall of the brake belt 52. The brake belt 52 is pressed tightly against the outer wall of the brake disc 51 through the fixing plate 53, so that the brake disc 51 can slow down the speed of the main shaft 4, and the main shaft 4 can slow down the speed of the winding wheel 3, so as to prevent the winding speed of the winding wheel 3 from being too fast and causing the PE pipe to be entangled during recovery. A fixing column 54 is fixedly mounted on the outer wall of the support plate 2, and a fixing ring 55 is fixedly sleeved on the outer wall of the fixing column 54. A mounting plate 56 is fixedly mounted on the outer wall of the fixing ring 55, and the outer wall of the mounting plate 56 is fixedly connected to one end of the connecting rod 57.

[0026] The above-mentioned adjusting mechanism 6 includes a connecting plate 61, which is fixedly installed on the outer wall of the supporting plate 2, and a mounting ring 62 is fixedly installed on the outer wall of the connecting plate 61.

[0027] In this embodiment, when the reel 3 recycles the PE tube, the brake belt 52 is pressed against the outer wall of the brake disc 51 through the fixing plate 53, so that the brake disc 51 can drive the main shaft 4 to slow down, and then the main shaft 4 drives the reel 3 to slow down, so as to prevent the reel 3 from winding up too fast and causing the PE tube to be entangled during the reeling, and the PE tube from being disordered during traction, and at the same time, by rotating the adjusting hand wheel 64, the adjusting hand wheel 64 can be moved in the direction of the mounting ring 62, so that the adjusting hand wheel 64 can adjust the tension spring 6 5 is compressed, and then the elastic force of the tension spring 65 pushes the adjusting hand wheel 64, so that the adjusting hand wheel 64 drives the adjusting screw rod 63 to move away from the mounting ring 62, and finally the adjusting screw rod 63 pulls the end fixing plate 53 to tighten the brake band 52, so that the brake band 52 further presses the outer wall of the brake disc 51, and the speed of the winding wheel 3 is further reduced. Similarly, the speed of the winding wheel 3 can be increased by rotating the adjusting hand wheel 64 in the opposite direction, which is convenient for adjusting the speed of the winding wheel 3.
