Description

Technical Field

[0001] The utility model relates to the technical field of an ecological restoration liquid spraying device for a park, in particular to an ecological restoration liquid spraying device for a park. Background Art

[0002] Lawn refers to grass that is artificially planted or maintained for greening and beautification. It is one of the symbols of the level of civilization of a country or a city. It refers to ground cover covered with grass and other fine plants with roots and stolons filling the soil surface. It is suitable for beautifying the environment, landscape, purifying the air, conserving water and soil, and providing outdoor activities and sports venues. In real life, parks are places for people to walk in their spare time, and a large number of people will gather. The walking and trampling of the same people will affect the lawn of the park, affecting the overall aesthetics of the park and the ecological environment of the park. Therefore, park managers will regularly spray the lawn with repair fluid.

[0003] An ecological restoration liquid spraying device for parks disclosed in announcement number CN216573691U realizes the movement of a fixed axis by extending and retracting an electric telescopic rod, and then realizes the angle adjustment of a hydraulic rod by moving the fixed axis in a through groove, and the distance and height adjustment of a spray head are realized in conjunction with the extension and retraction of the hydraulic rod, so that when the device is in a certain position, the lawn can be sprayed in a larger range, thereby avoiding repeated movement of personnel and improving construction efficiency.

[0004] However, the ecological restoration liquid spraying device used in the park has the following disadvantages:

[0005] If the spraying distance is only achieved through hydraulic extension, the maximum length of the hydraulic extension will result in an insufficient adjustable spraying range, which will affect the spraying efficiency.

[0006] When spraying a large area of ​​grass, it is sometimes necessary to move the spray device to the grass. The grass is uneven, and the spray device moves on its surface for a long time. The bumps will cause the connections in the spray device to loosen, causing the hardware structure to loosen and fall off.

[0007] In view of this, the present utility model is proposed. Utility Model Content

[0011] The spraying structure comprises a device box fixedly connected to the top surface of the bottom plate, a driving structure is fixedly connected to the side of the device box, a hose is overlapped on the side of the driving structure, and a side plate is fixedly connected to the side of the device box.

[0012] Optionally, the driving structure includes a driving motor fixedly connected to the back of the equipment box, the output end of the driving motor is fixedly connected to an extrusion block, both ends of the extrusion block are provided with a rotating groove, a rotatable roller is arranged inside the rotating groove, the extrusion block reciprocally squeezes the hose to generate negative pressure inside the hose, the repair fluid inside the water tank is extracted and sprayed, and the flow rate and water pressure of the repair fluid can be adjusted by adjusting the speed of the driving motor.

[0013] Optionally, a sleeve hole is opened on the top surface of the device box, the inner diameter of the sleeve hole matches the outer diameter of the hose, and a hose is sleeved inside the sleeve hole. The hose is made of a relatively soft material and can withstand high-frequency and long-term extrusion deformation of the extrusion block, thereby increasing its service life.

[0014] Optionally, the buffer structure includes a fixed plate axially symmetrically fixedly connected to the bottom surface of the base plate, the side of the fixed plate is rotatably connected to a deformable structure, the side of the deformable structure is rotatably connected to a movable block, the bottom surface of the movable block is fixedly connected to a hydraulic buffer, the bottom surface of the hydraulic buffer is fixedly connected to a connecting plate, the surface of the hydraulic buffer is sleeved with a buffer spring, and the buffer structure can buffer the vibration force generated by the universal wheel moving on bumpy grass to avoid damage to other structures.

[0015] Optionally, the deformation structure includes a rotating block rotatably connected to the side of the fixed plate, the side of the rotating block is fixedly connected to a spring plate, one end of the spring plate is rotatably connected to a movable block through another rotating block, and the spring can provide support for the universal wheel while also buffering vibration to a certain extent, thereby improving shock absorption capacity.

[0016] Optionally, a water inlet is provided on the top surface of the water tank, and a threaded pipe is provided on the top surface of the water inlet. A sealing cover is threadedly connected to the surface of the threaded pipe.

[0017] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0018] 1. The park uses an ecological restoration liquid spraying device. Through the setting of the spraying structure, the external power supply of the driving motor starts to work, driving the extrusion block fixed at its output end to rotate inside the equipment box, so that the hose connected inside the equipment box is reciprocated by the extrusion block, so that negative pressure is generated inside the hose. The negative pressure inside the hose draws the restoration liquid inside the water tank for spraying. By adjusting the speed of the driving motor, the extrusion block squeezes the hose at different frequencies, which will change the negative pressure inside it, so that the flow rate and water pressure of the restoration liquid passing through the hose can be changed. The faster the flow rate and water pressure of the restoration liquid, the farther it is sprayed, and vice versa, the closer it is sprayed, thereby achieving a more flexible adjustment of the spraying range and distance, avoiding the use of a telescopic structure that can only adjust the spraying distance in a small range.

[0019] 2. The park uses an ecological restoration liquid spraying device. Through the setting of the buffer structure, the vibration generated by the universal wheel moving on the bumpy road will drive the connecting plate to move upward, and the connecting plate will drive the buffer spring to compress. At the same time, the excess vibration force will drive the moving block to deform the spring plate. During the compression and deformation of the buffer spring and the spring plate, the vibration force is absorbed and buffered. Then, the rebound force brought by the reset of the buffer spring and the spring plate will squeeze the hydraulic buffer, making its reset speed slower to avoid additional vibration caused by rapid rebound, thereby achieving the effect of facilitating the movement of the spraying device on the grass while avoiding the transmission of vibration force to the structural connection inside the spraying device and causing the structure to loosen.

[0033] By setting the spraying structure 7, the external power supply of the driving motor 721 starts to work, driving the extrusion block 722 fixed at its output end to rotate inside the equipment box 71, so that the hose 73 sleeved inside the equipment box 71 is reciprocatedly squeezed by the extrusion block 722, so that negative pressure is generated inside the hose 73, and the negative pressure inside the hose 73 draws out the repair liquid inside the water storage tank 3 for spraying.

Finally, the drive motor 721 is connected to an external power supply. When it starts working, it drives the extrusion block 722 fixed at its output end to rotate inside the equipment box 71, so that the hose 73 connected inside the equipment box 71 is reciprocated by the extrusion block 722, so that negative pressure is generated inside the hose 73. The negative pressure inside the hose 73 draws out the repair liquid inside the water tank 3 for spraying. By adjusting the speed of the driving motor 721, the extrusion block 722 squeezes the hose 73 at different frequencies, which will change the negative pressure inside it, so that the flow rate and water pressure of the repair liquid passing through the hose 73 can be changed.
