Description

Technical Field

[0001] The utility model relates to the technical field of lawn maintenance equipment, in particular to a punching device for lawns. Background Technique

[0002] A lawn refers to a grassland established or maintained artificially, which usually plays a role in greening and beautifying. It is an important part of the garden scenery and also an important outdoor activity place. The lawn can not only improve the beauty of the environment, but also help to reduce dust, fix soil, provide oxygen and other ecological functions. With the passage of time and human trampling, the surface soil of the lawn will gradually become hard and form a crust, which limits the respiration and growth of the lawn roots and affects the health and beauty of the lawn. Therefore, in order to improve the air permeability and water permeability of the lawn, a punching device for lawns is needed.

[0003] According to the search, the Chinese patent document, publication number: CN212786525U, discloses a punching device for lawns. Through the electrical control of the second electric telescopic rod by the control panel, and at the same time, through the fixed connection between the telescopic movable plate and the second electric telescopic rod, and the threaded connection between the telescopic movable plate and the punching needle, the punching needle can move randomly in the movement direction of the second electric telescopic rod, so as to control the length of the punching needle extending outside the roller piece, avoiding the problem that the punching depth of the traditional punching device for lawns cannot be adjusted. However, in the actual use process of this device, since the punching needle is not vertically inserted into the lawn, the punching angle and diameter cannot be accurately controlled, etc., reducing the overall practicability; in addition, since multiple punching needles are connected to the same telescopic movable plate, when they are inserted into the lawn together, not only the punching resistance is large, increasing the operation difficulty of the staff, but also the load on the device connectors is large, affecting the overall service life. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0006] (2) Technical Solutions

[0007] To achieve the above object, the present utility model provides the following technical solutions: A punching device for lawns, including a base, on the top surface of the base, a hydraulic cylinder is fixedly installed, the output shaft of the hydraulic cylinder is fixedly connected to a support, on the inner side surface of the support, a working box is fixedly installed, on the rear side surface of the working box, a driving motor is fixedly installed, on the inner side surface of the working box, a rotating shaft and a limiting plate are installed, on the outer side surface of the rotating shaft, a gear is fixedly installed, on the front side surface of the gear, a connecting rod is installed, the end of the connecting rod away from the gear is connected to a moving column, on the bottom surface of the moving column, a nail plate is fixedly installed, and on the bottom surface of the nail plate, punching nails are fixedly installed.

[0008] Preferably, the number of both the hydraulic cylinder and the support is set to two, and through holes are provided on the top surface of the base, and the working box is installed inside the through holes.

[0009] Through the above technical solution, when starting the two hydraulic cylinders, the output shafts of the two hydraulic cylinders can drive the two supports to move respectively, and then can drive parts such as the working box to move in the vertical direction. Therefore, the distance between it and the lawn can be effectively adjusted, and then the depth of punching can be controlled, improving the overall practicability of the device.

[0010] Preferably, the number of both the rotating shaft and the gear is set to multiple, and multiple gears are meshed with each other in pairs, and the output shaft of the driving motor is fixedly connected to the rear side surface of one of the rotating shafts.

[0011] Through the above technical solution, when starting the driving motor, the output shaft of the driving motor can drive one of the rotating shafts and the gear to rotate, and this gear can then mesh with another gear and the rotating shaft to rotate. Similarly, multiple gears and rotating shafts can be driven to rotate in sequence, improving the overall practicability of the device.

[0012] Preferably, the number of both the connecting rod and the moving column is set to multiple, and multiple moving columns are slidably installed inside the limiting plate.

At the same time, since multiple punching nails are evenly distributed on the bottom surfaces of multiple nail plates, the lawn can be effectively punched regularly, improving soil aeration, promoting root growth, and enhancing the overall quality of the lawn.

[0016] Preferably, four casters are installed on the bottom surface of the base, and a push rod is fixedly installed on the top surface of the base.

[0017] Through the above technical solution, the four casters and the push rod can facilitate the staff to push the device for punching. At the same time, pushing the device at different speeds can also well control the punching interval distance, improving the overall practicality of the device.

[0018] Compared with the prior art, the present utility model provides a punching device for lawns, having the following beneficial effects:

[0019] 1. By starting two hydraulic cylinders of the present utility model, the output shafts of the two hydraulic cylinders can drive two supports to move respectively, and then drive parts such as the working box to move in the vertical direction. Therefore, the distance between it and the lawn can be effectively adjusted, and then the punching depth can be controlled; through the four casters and the push rod, it is convenient for the staff to push the device for punching. At the same time, pushing the device at different speeds can also well control the punching interval distance, improving the overall practicality of the device.

[0020] 2. By starting the driving motor of the present utility model, the output shaft of the driving motor can drive one of the rotating shafts and the gear to rotate. This gear can then engage another gear and the rotating shaft to rotate. Similarly, multiple gears and rotating shafts can be driven to rotate in sequence. Multiple gears can drive multiple connecting rods to move respectively, and multiple connecting rods can drive multiple moving columns to move. Since multiple moving columns are all slidably installed inside the limiting plate, multiple gears and connecting rods can drive multiple moving columns and punching nails to move reciprocally in the vertical direction. At the same time, since multiple connecting rods are respectively installed at different positions of multiple gears, the lawn can be effectively punched in a staggered manner, not only improving soil aeration, promoting root growth, and enhancing the overall quality of the lawn, but also improving the overall working efficiency and service life of the device.

[0027] Specifically, the numbers of the hydraulic cylinders 2 and the supports 3 are both set to two, and a through hole 13 is opened on the top surface of the base 1, and the working box 4 is installed inside the through hole 13. The advantage is that when starting the two hydraulic cylinders 2 through this structure, the output shafts of the two hydraulic cylinders 2 can drive the two supports 3 to move respectively, and then can drive parts such as the working box 4 to move in the vertical direction. Therefore, the distance between it and the lawn can be effectively adjusted, and then the punching depth can be controlled, improving the overall practicability of the device.

[0028] Specifically, the numbers of the rotating shafts 6 and the gears 8 are both set to multiple, and multiple gears 8 are meshed with each other in pairs, and the output shaft of the driving motor 5 is fixedly connected to the rear side surface of one of the rotating shafts 6. The advantage is that when starting the driving motor 5 through this structure, the output shaft of the driving motor 5 can drive one of the rotating shafts 6 and the gear 8 to rotate, and this gear 8 can then mesh with another gear 8 and the rotating shaft 6 to rotate. Similarly, multiple gears 8 and rotating shafts 6 can be driven to rotate in sequence, improving the overall practicability of the device.

[0029] Specifically, the number of connecting rods 9 and moving columns 10 are both set to be multiple, and the multiple moving columns 10 are all slidably installed inside the limiting plate 7. The advantage is that with this structure, when the multiple gears 8 rotate, the multiple gears 8 can respectively drive the multiple connecting rods 9 to move, and at the same time, the multiple connecting rods 9 can drive the multiple moving columns 10 to move. Since the multiple moving columns 10 are all slidably installed inside the limiting plate 7, the multiple gears 8 and connecting rods 9 can drive the multiple moving columns 10 and punching nails 12 to do reciprocating motion in the vertical direction.

The output shaft of the driving motor 5 can drive one of the rotating shafts 6 and the gear 8 to rotate. This gear 8 can then mesh with another gear 8 and the rotating shaft 6 to rotate. Similarly, multiple gears 8 and rotating shafts 6 can be driven to rotate in sequence. The multiple gears 8 can drive multiple connecting rods 9 to move respectively, and the multiple connecting rods 9 can drive multiple moving columns 10 to move. Since the multiple moving columns 10 are all slidably installed inside the limiting plate 7, the multiple gears 8 and the connecting rods 9 can drive the multiple moving columns 10 and the punching nails 12 to move reciprocally in the vertical direction. At the same time, since the multiple connecting rods 9 are respectively installed at different positions of the multiple gears 8, the staggered punching of the lawn can be effectively realized, which not only improves the air permeability of the soil, promotes root growth, and enhances the overall quality of the lawn, but also improves the overall working efficiency and service life of the device. Through the four casters 14 and the push rod 15, it is convenient for the staff to push the device for punching.
