Description

Technical Field

[0001] This utility model relates to the field of ground watering and maintenance technology, and more specifically, to a ground watering and maintenance device. Background Technology

[0002] Ground curing involves artificially creating certain humidity and temperature conditions to allow freshly poured concrete to harden and strengthen normally, or to accelerate its hardening and strength development. This requires manually sprinkling water on the concrete surface for curing.

[0003] In ground maintenance operations, existing sprinkler systems generally use batteries to power the water pumps. The battery life is limited by capacity, and in large areas or long-term operation scenarios, frequent charging or battery replacement is required, affecting the continuity of operations. At the same time, most of the nozzles of existing sprinkler systems are fixedly installed at the bottom of the floor. When driving on bumpy and uneven roads, the spraying parts are prone to contact with the ground, causing the nozzles to become clogged or damaged, affecting the sprinkling and maintenance effect.

[0004] Therefore, we have made improvements to this and proposed a ground watering maintenance device. Utility Model Content

[0005] The purpose of this utility model is to address the fact that in ground maintenance operations, existing sprinkler systems generally use a battery-powered water pump operation mode. The battery's range is limited by its capacity, and in large-area or long-term operation scenarios, frequent charging or battery replacement is required, affecting the continuity of operations. At the same time, most of the nozzles of existing sprinkler systems are fixedly installed at the bottom of the floor. When driving on bumpy or uneven roads, the spraying parts are prone to contact with the ground, causing the nozzles to become clogged or damaged, thus affecting the sprinkling and maintenance effect.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A ground watering and maintenance device includes a base plate, a water tank fixedly installed on top of the base plate, a water inlet at the top of the water tank, two casters and one universal wheel at the bottom of the base plate, a pump body fixedly installed at the bottom of the base plate, a drive assembly between the casters and the input shaft of the pump body, the drive assembly including a drive rod fixedly installed between the two casters and rotatably engaged with the bottom of the base plate, a first transmission shaft rotatably engaged with the drive rod at the bottom of the base plate, a second transmission shaft engaged with the first transmission shaft at the input shaft of the pump body, a water inlet pipe connected to the water tank at the water inlet of the pump body, a spray plate near the universal wheel at the bottom of the base plate, and a water delivery hose installed between the water inlet of the spray plate and the water outlet of the pump body.

[0008] Furthermore, the bottom of the base plate is equipped with a fixed frame that rotates with the first drive shaft, and the periphery of the drive rod and one end of the first drive shaft are each equipped with a meshing bevel gear.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figure 1-4 A ground watering and maintenance device includes a base plate 1, a water tank 2 fixedly installed on the top of the base plate 1, a water inlet 3 at the top of the water tank 2, two movable wheels 4 and a universal wheel 5 at the bottom of the base plate 1, a pump body 7 fixedly installed at the bottom of the base plate 1, a drive assembly 6 between the movable wheels 4 and the input shaft of the pump body 7, the drive assembly 6 including a drive rod 601 fixedly installed between the two movable wheels 4 and rotatably engaged with the bottom of the base plate 1, a first transmission shaft 603 rotatably engaged with the drive rod 601 at the bottom of the base plate 1, a second transmission shaft 605 engaged with the first transmission shaft 603 at the input shaft of the pump body 7, a water inlet pipe 9 connected to the water tank 2 at the water inlet of the pump body 7, a spray plate 11 provided on the bottom of the base plate 1 near the universal wheel 5, and a water delivery hose 10 installed between the water inlet of the spray plate 11 and the water outlet of the pump body 7.

[0025] Specifically, when the device moves, the moving wheel 4 rotates, which drives the first transmission shaft 603 to rotate via the drive rod 601. The bevel gear 604 on the first transmission shaft 603 meshes with the bevel gear 604 on the drive rod 601, transmitting power to the first transmission shaft 603. The first transmission shaft 603 meshes with the tooth groove 609 of the connecting cylinder 608 via the connecting tooth 606, further transmitting power to the second transmission shaft 605, thereby driving the input shaft of the pump body 7 to rotate. The pump body 7 draws water from the water tank 2 through the water inlet pipe 9, and then delivers the water to the spray plate 11 through the water delivery hose 10, and finally sprays it out from the nozzle 15 to complete the watering maintenance operation.

[0026] Please refer to Figure 2-4 The bottom of the base plate 1 is equipped with a fixed frame 602 that rotatably engages with the first drive shaft 603. The periphery of the drive rod 601 is equipped with bevel gears 604 that mesh with one end of the first drive shaft 603. Protective shells 8 are fixedly installed on both the two bevel gears 604 and the outside of the pump body 7. Multiple connecting teeth 606 are installed on the periphery of the ends of the first drive shaft 603 and the second drive shaft 605 that are close to each other. An L-shaped frame 607 is slidably fitted on the base plate 1. The lateral side of the L-shaped frame 607 is located at the bottom of the base plate 1, and one end is rotatably fitted with a connecting cylinder 60. 8. The inner wall of the connecting cylinder 608 is provided with a plurality of tooth grooves 609 that cooperate with the connecting teeth 606. The connecting teeth 606 on the second transmission shaft 605 are rounded at the end near the connecting cylinder 608. An adjusting plate 610 is installed on the top of the longitudinal side of the L-shaped frame 607. Two positioning pins 611 are slidably engaged on both sides of the adjusting plate 610. A displacement groove 612 is provided through the upper side of the bottom plate 1 that is slidably engaged with the longitudinal side of the L-shaped frame 607. Two positioning grooves 613 are provided on both sides above the bottom plate 1 that cooperate with the positioning pins 611.

[0027] Specifically, the design of the connecting tooth 606 enables power transmission between the first drive shaft 603 and the second drive shaft 605. The end of the connecting tooth 606 on the second drive shaft 605 near the connecting cylinder 608 is rounded to facilitate the meshing of the connecting cylinder 608 and the connecting tooth 606. The L-shaped frame 607 slides on the base plate 1 through the displacement groove 612. The positioning pin 611 on the adjusting plate 610 can be inserted into the positioning groove 613 to fix the position of the L-shaped frame 607, thereby adjusting the meshing state of the connecting cylinder 608 and the connecting tooth 606. When water spraying is not required, the power connection between the pump body 7 and the drive rod 601 is disconnected.

[0028] Please refer to Figure 4The bottom of the base plate 1 is equipped with upright blocks 13 on both sides near the casters 5. Each of the two upright blocks 13 has a limiting groove 14 on its opposite side. The spray plate 11 is equipped with limiting blocks 12 on both sides that slide with the limiting grooves 14. The bottom of the spray plate 11 is equipped with a plurality of nozzles 15 in a linear array. The bottom of the spray plate 11 is rotatably mounted with a lifting wheel 16, which is located in front of the nozzles 15. A handrail 17 is installed on the rear side above the base plate 1. The lifting wheel 16 can lift the spray plate 11 on bumpy roads, reducing the possibility of the nozzles 15 at the bottom of the spray plate 11 coming into contact with the ground and causing blockage or damage.

[0029] Specifically, the spray plate 11 is slidably engaged with the limiting groove 14 on the vertical block 13 via the limiting block 12, which restricts the left and right movement of the spray plate 11 and ensures its stability during movement. When the device is traveling on a bumpy road, the lifting wheel 16 will contact the ground and generate an upward force to lift the spray plate 11, preventing the nozzle 15 from contacting the ground and reducing nozzle clogging or damage.

[0030] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
