Abstract
Description
Technical Field
[0001] The utility model relates to the field of greening machinery, and particularly relates to a lawn punching and landfilling integrated machine. Background Art
[0002] After a year of growth, due to the attachment and extension of the root system on the ground surface of the lawn, as well as the implementation of maintenance operations such as fertilization and watering, the air and water permeability of the soil surface becomes worse and worse, which in turn leads to soil compaction. To improve the physical and chemical properties of the soil, enhance its water and air permeability, accelerate the decomposition of organic residues, better promote the healthy growth of the turf root system, improve the absorption of water and fertilizer by the roots, and prepare for the healthy growth of the lawn in the second year, it is necessary to regularly carry out punching maintenance operations on the lawn every year. After punching, in order to further ensure the flatness and density of the lawn, fine sand needs to be filled into the holes.
[0003] In the prior art, punching and landfilling are operated by two people. The person in front is responsible for punching, and the person behind fills the holes with sand. The two need to cooperate well to complete the operation quickly and efficiently. However, due to individual differences, it is very difficult to achieve perfect cooperation. If the person filling the sand behind moves relatively slowly, the punching tool is easily covered by the surrounding grass after punching and lifting up, resulting in the person filling the sand not being able to see the hole and missing the filling, thus failing to achieve the expected technical effect. Summary of the Utility Model
[0004] In view of the above problems, the utility model provides a lawn punching and landfilling integrated machine, which can complete two operations of punching and landfilling with one person's operation, saving time and labor.

[0022] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.
[0023] As Figures 1-4 shown, the present utility model discloses a lawn punching and landfill integrated machine, which includes an outer sleeve 3. A punching tip is provided at the lower end of the outer sleeve for piercing into the lawn underground. For convenient operation and to increase and enhance the piercing force, a foot pedal 9 is provided at the lower part of the outer side of the outer sleeve. Two such foot pedals are provided and are symmetrically distributed about the center line of the outer sleeve. This setting enables people with different operating habits to use it conveniently. For convenient carrying, armrests 12 are symmetrically installed on the outer side of the upper end of the outer sleeve for supporting the entire device.
[0024] A switch cylinder 5 and a sand cylinder 6 are sequentially sleeved inside the outer sleeve 3. Among them, multiple long slot holes are provided on the side wall of the switch cylinder, and multiple connecting rods 4 are provided on the side wall of the outer sleeve 3. The connecting rod 4 passes through the long slot holes and is fixedly connected to the outer wall of the sand cylinder 6. The connecting rod can be a screw rod and is threadedly connected by machining threaded holes on the outer sleeve and the sand cylinder. It can also be a pin shaft and is inserted by machining pin holes on the outer sleeve and the sand cylinder. Among them, the threaded holes and pin holes on the outer sleeve are through holes, and the threaded holes and pin holes on the sand cylinder cannot penetrate the inner wall of the sand cylinder.
[0025] Three sand filling blades 7 are hinged to the lower end of the sand cylinder 6 through a hinge 8. The sand filling blades are inverted triangles, and the lower ends of the three sand filling blades overlap each other to form a closed tip or are separated by a set distance to form a sand leakage port. A conical opening is provided at the lower end of the switch cylinder 5, and the conical opening covers the outside of the three sand filling blades 7.
[0026] Three or four guide rods 10 are provided at the upper end of the switch cylinder 5. A spring 11 is sleeved outside each guide rod. The spring is a cylindrical helical compression spring. A limiting ring 13 corresponding to the number of guide rods 10 is provided on the inner wall of the outer sleeve. The limiting ring is sleeved outside the guide rod 10, and the lower end of the spring 11 abuts against the upper surface of the limiting ring 13. The guide rod can move up and down within the limiting ring. The upper ends of the multiple guide rods protrude out of the top of the outer sleeve 3 together and are jointly connected to a top ring 2, and the top ring is sleeved outside the sand cylinder 6.
[0027] As Figures 1-2As shown, in the state without sand filling, the upper end of the spring 11 pushes the top ring up to the highest position, and the switch cylinder 5 rises to the highest position. At this time, the conical opening below the switch cylinder 5 tightly surrounds the three sand filling blades 7, and the three sand filling blades 7 form a closed inverted conical structure to store the sand in the sand cylinder.
[0028] As Figures 3-4 shown, when sand needs to be filled into the hole, press down the top ring 2. The top ring compresses the spring 11 and deforms, driving the switch cylinder 5 to move downward, and the conical opening at the lower end leaves the three sand filling blades 7. Since the hinge connecting the three sand filling blades 7 is a self - resetting hinge with a torsion spring, the lower ends of the three sand filling blades 7 are separated from each other under the action of the torsion spring reset, forming a sand leakage opening, and the sand in the sand cylinder leaks into the hole to fill the hole. After reaching the set sand leakage amount (for example, when it is observed from the upper surface of the sand cylinder that the sand plane no longer drops), release the top ring 2, and under the reset action of the spring 11, the top ring 2 is pushed upward. The top ring drives the switch cylinder 5 to move upward, and the conical opening at the lower end of the switch cylinder 5 wraps the three sand filling blades to seal, and the sand no longer leaks out.
[0029] An upper cover 1 is provided at the upper end of the sand cylinder 6 to temporarily seal the sand cylinder when it is not in use or when transferring the working location, preventing the sand from leaking out from the top of the sand cylinder 6.
[0030] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
