Description

Technical Field

[0001] This utility model relates to the field of lawn maintenance equipment technology, and in particular to a lawn aerator. Background Technology

[0002] Lawn aeration is a method of lawn maintenance. It improves soil aeration, facilitates water penetration, increases nutrient absorption, and stimulates root growth. Currently, lawn aeration equipment generally falls into two categories: large-scale automated equipment, typically used for relatively flat, large-area lawns, and manual aeration devices, operated manually by gardeners, typically used for small or uneven lawns. For example, Chinese Patent No. 2024208993276 discloses a lawn aeration device; however, this device suffers from the problem of soil easily entering the blades during each aeration, making cleanup difficult. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a lawn aerator that makes it easier to clean the soil in the channel after each aeration and is more convenient to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lawn aerator includes a connecting seat and a handle rod fixedly connected perpendicularly to the connecting seat. A connecting frame is provided on the lower side of the connecting seat, and the connecting frame is distributed parallel to the connecting seat. Both ends of the connecting frame are fixedly connected to the connecting seat via guide rods. The connecting frame is provided with a plurality of equally spaced cylindrical blades, and a lower pedal is provided on the side of the connecting frame. A lifting seat is provided between the connecting seat and the connecting frame. Both ends of the lifting seat are slidably connected to the guide rods. The lifting seat is provided with a plurality of top rods distributed coaxially with the cylindrical blades. The lower end of each top rod is provided with a pressure block extending into the upper end of the cylindrical blade. An upper pedal is provided on the side of the lifting seat.

[0006] By adopting the above technical solution: when in use, hold the handle, with the blade perpendicular to the lawn surface, and then step on the lower pedal to make the blade pierce the lawn and insert into the soil. The soil enters the blade. Then, step on the upper pedal and pull the handle upward to make the lifting seat move downward along the guide rod, which drives the pressure block to push out the soil in the blade. This eliminates the need for manual cleaning of the blade and makes it more convenient to use.

[0007] Preferably, the guide rod is provided with a compression spring on the lower side of the lifting seat to assist the lifting seat in rising and resetting. The compression spring assists the lifting seat in resetting.

[0008] Preferably, the handle rod is a hollow tubular structure with an elongated slot on its side. A sliding rod is located inside the handle rod, with its lower end fixedly connected to the lifting seat. A handle extends from the elongated slot onto the upper side of the sliding rod. In cases where the soil is highly adhesive, all the pressure blocks may enter the cutter head after the lifting seat descends. The residual soil on the inner wall of the cutter head can prevent the lifting seat from rising and resetting. In this situation, pulling the handle upwards can reset the lifting seat.

[0009] Preferably, the connecting frame includes an upper connecting plate and a lower connecting plate. The upper connecting plate has a row of upper positioning holes, and the lower connecting plate has lower positioning holes coaxially distributed with the upper positioning holes. A limiting protrusion is provided on the upper outer wall of the cylindrical cutter. The cylindrical cutter slides through the lower positioning holes, and the limiting protrusion is located between the upper and lower connecting plates. Both ends of the upper connecting plate are fixedly connected to the guide rod, and the lower connecting plate and the upper connecting plate are detachably connected by bolts. When the cylindrical cutter is worn or damaged, the lower connecting plate can be disassembled, allowing any cylindrical cutter to be freely replaced.

[0010] Preferably, the upper end of the push rod is threadedly connected to the lifting seat, the pressure block is clearance-fitted with the inner hole of the cylinder cutter, and the edge of the pressure block is provided with several grooves. This allows for easy replacement of the push rod when damaged, and the grooves reduce the frictional resistance of the pressure block as it moves within the cylinder cutter.

[0011] Preferably, the upper and lower pedals are located on the same side of the connecting seat. The upper and lower pedals further enhance operational convenience.

[0012] Therefore, this utility model has the beneficial effect of making it easier to clean the mud in the channel after each drilling and making it more convenient to use. Attached Figure Description

Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0020] like Figures 1-5 The lawn aerator shown includes a connecting seat 1 and a handle rod 2 that is vertically fixedly connected to the connecting seat 1. A connecting frame 3 is provided on the lower side of the connecting seat 1. The connecting frame 3 is parallel to the connecting seat 1. Both ends of the connecting frame 3 are fixedly connected to the connecting seat 1 through guide rods 4. The connecting frame 3 is provided with a plurality of equally spaced cylindrical blades 5. A lower pedal 30 is provided on the side of the connecting frame 3. A lifting seat 6 is provided between the connecting seat 1 and the connecting frame 3. Both ends of the lifting seat 6 are slidably connected to the guide rods 4. A compression spring 8 is provided on the lower part of the guide rods 4 to assist the lifting seat 6 in rising and resetting. The lifting seat 6 is provided with a plurality of top rods 7 that are coaxially distributed with the cylindrical blades 5. The lower end of the top rod 7 is provided with a pressure block 70 that extends into the upper end of the cylindrical blades 5. An upper pedal 60 is provided on the side of the lifting seat 6.

[0021] In this embodiment, the upper pedal 60 and the lower pedal 30 are located on the same side of the connecting seat 1; the cylindrical blade is a cylindrical structure that runs vertically through the body, and the lower end has an annular cutting edge that can pierce the turf. The upper end of the top rod 7 is threadedly connected to the lifting seat 6, and the pressure block 70 is clearance-fitted with the inner hole of the cylindrical blade 5. Several grooves 700 are provided on the edge of the pressure block 70.

[0022] The handle rod 2 has a hollow tubular structure. The side of the handle rod 2 is provided with an elongated slot 20. The handle rod 2 is provided with a slide rod 21. The lower end of the slide rod 21 is fixedly connected to the lifting seat 6. The upper end of the slide rod 21 is provided with a handle 22 that extends out of the handle rod 2 from the elongated slot 20.

[0023] The connecting frame 3 includes an upper connecting plate 31 and a lower connecting plate 32. The upper connecting plate 31 is provided with a row of upper positioning holes 310, and the lower connecting plate 32 is provided with lower positioning holes 320 coaxially distributed with the upper positioning holes 310. A limiting protrusion ring 50 is provided on the upper outer wall of the tube cutter 5. The tube cutter 5 slides through the lower positioning hole 320. The limiting protrusion ring 50 is located between the upper connecting plate 31 and the lower connecting plate 32. The two ends of the upper connecting plate 31 are fixedly connected to the guide rod 4, and the lower connecting plate 32 and the upper connecting plate 31 are detachably connected by bolts 321.

[0024] Referring to the accompanying drawings, the principle of this utility model is as follows: In use, hold the handle, with the blade perpendicular to the lawn surface, and then step on the lower pedal. This causes the blade to pierce the lawn and insert into the soil, allowing soil to enter the blade. Next, step on the upper pedal and pull the handle upwards, causing the lifting seat to move downwards along the guide rod. This moves the pressure block to push the soil out of the blade. After releasing the second pedal, the lifting seat automatically returns to its original position under the action of the compression spring. If the friction between the soil in the blade and the pressure block is too great, preventing the lifting seat from automatically returning to its original position, you can manually pull the handle to assist in resetting it. Using this type of lawn aerator eliminates the need for manual cleaning of the blade, making it more convenient to use.
