[0001] This utility model relates to the field of turf maintenance technology, and in particular to a turf scraping mechanism and a turf maintenance station. Background Technology
[0002] Existing lawn maintenance typically involves weeding, mowing, loosening the soil, and fertilizing.
[0003] Current lawn loosening work mainly involves aerating the lawn with a hole-drilling devices to improve the physical properties of the lawn and promote soil aeration and water penetration.
[0004] Existing drilling devices mainly consist of a housing, a drive mechanism, and a punching tube. The drive mechanism and the punching tube are installed inside the housing, with the punching tube mounted at the output end of the drive mechanism. The drive mechanism is used to extend and retract the punching tube at the bottom of the housing. During drilling, the drive mechanism drives the punching tube into the soil and then brings out the soil inside the punching tube. Because the soil at deeper depths is more moist, some soil adheres to the outside of the punching tube. As the punching tube enters and exits the drilling device, it brings some of this soil into the device, affecting the drilling accuracy and reducing its lifespan.
[0005] In view of this, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slag scraping mechanism and a turf maintenance station to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the first aspect of this utility model provides a slag scraping mechanism. The bottom of the housing of the punching device is provided with an installation plate. The middle of the installation plate has a pipe hole for passing through the punching pipe. The mechanism includes at least one slag scraper. The at least one slag scraper is installed on the installation plate. The middle of the slag scraper has a through hole for passing through the punching pipe. The inner wall of the through hole is in contact with the punching pipe.
[0008] In a further technical solution, there are two slag scrapers, namely a first slag scraper and a second slag scraper. The first slag scraper and the second slag scraper are respectively installed on the mounting plate. Correspondingly, there are two through holes, namely a first through hole opened in the middle of the first slag scraper and a second through hole opened in the middle of the second slag scraper. The inner walls of the first through hole and the second through hole are respectively attached to the perforated pipe.
[0009] In a further technical solution, the middle part of the first scraper plate protrudes towards the axis to form multiple first scraper blades, and the multiple first scraper blades surround each other to form the first through hole; the middle part of the second scraper plate protrudes towards the axis to form multiple second scraper blades, and the multiple second scraper blades surround each other to form the second through hole.
[0010] In a further technical solution, a first through groove is formed between two adjacent first scraper blades, and the second scraper blade overlaps and covers the first through groove.
[0011] In a further technical solution, a second through groove is formed between two adjacent second scraper blades, and the first scraper blade overlaps and covers the second through groove.
[0012] In a further technical solution, the diameter of the tube hole is larger than the diameters of the first through hole and the second through hole.
[0013] A further technical solution also includes multiple connectors, with the first end of each connector connected to the first scraper plate and the second end of each connector connected to the second scraper plate.
[0014] In a further technical solution, the first scraper is installed on the outer side of the mounting plate, the second scraper is installed on the inner side of the mounting plate, and the connector penetrates through the mounting plate.
[0015] In a further technical solution, the bottom of the perforated tube has at least one slit along the axial direction.

[0017] Compared with the prior art, this utility model brings the following technical effects:
[0018] The scraping mechanism of this utility model limits the outside of the punching pipe hole by setting the scraping plate. When the driving mechanism drives the punching pipe in and out of the housing, the scraping plate blocks the soil attached to the outside of the punching pipe, preventing the soil from being carried into the housing by the punching pipe, thereby reducing the maintenance time of the punching device and extending the service life of the punching device.
[0019] The turf maintenance station of this utility model includes all the technical features and effects of the sludge scraping mechanism, so they will not be described in detail here. Attached Figure Description

[0037] Example
[0038] See Figure 1-5As shown, the bottom of the housing 1 of the slag scraping mechanism and the punching device is provided with a mounting plate 11. The mounting plate 11 has a hole 111 in its center for the passage of the punching pipe 2. It includes at least one scraper plate, which is mounted on the mounting plate 11. The scraper plate has a through hole in its center for the passage of the punching pipe 2, and the inner wall of the through hole is in contact with the punching pipe 2. The scraper plate limits the movement of the punching pipe hole 111. When the driving mechanism moves the punching pipe 2 in and out of the housing 1, the scraper plate blocks the dirt adhering to the outside of the punching pipe 2, preventing dirt from being carried into the housing 1 by the punching pipe 2, thereby reducing the maintenance time of the punching device and extending its service life.
[0039] See Figure 1-3 As shown, in a preferred embodiment, there are two slag scrapers, namely a first slag scraper 3 and a second slag scraper 4. The first slag scraper 3 and the second slag scraper 4 are respectively installed on the mounting plate 11. Correspondingly, there are two through holes, namely a first through hole 31 opened in the middle of the first slag scraper 3 and a second through hole 41 opened in the middle of the second slag scraper 4. The inner walls of the first through hole 31 and the second through hole 41 are respectively attached to the perforated pipe 2.
[0040] By setting the first scraper 3 and the second scraper 4, the mud on the outside of the perforated pipe 2 is cleaned, so that the mud can be cleaned more thoroughly.
[0041] In other specific embodiments, the number of scraper blades may be only one. When there is only one scraper blade, it is positioned on the outside of the mounting plate 11 to block the soil.
[0042] See Figure 3 As shown, in a further specific embodiment, the middle part of the first scraper plate 3 protrudes towards the axis to form multiple first scraper blades 32, and the multiple first scraper blades 32 surround each other to form the first through hole 31. The middle part of the second scraper plate 4 protrudes towards the axis to form multiple second scraper blades 42, and the multiple second scraper blades 42 surround each other to form the second through hole 41.
[0043] This design allows both the first scraper blade 32 and the second scraper blade 42 to have a certain degree of elasticity, thus enabling them to fit closer to the outside of the perforated pipe 2 and to clean the mud more effectively.
[0044] See Figure 1-3As shown, in a further specific embodiment, a first through groove 33 is formed between two adjacent first scraper blades 32, and the second scraper blade 42 overlaps and covers the first through groove 33. A second through groove 43 is formed between two adjacent second scraper blades 42, and the first scraper blade 32 overlaps and covers the second through groove 43. The first scraper plate 3 is installed on the outer side of the mounting plate 11, the second scraper plate 4 is installed on the inner side of the mounting plate 11, and the connector 5 penetrates the mounting plate 11.
[0045] The first scraper blade 32 first cleans the soil attached to the outside of the punching pipe 2. Some of the soil will pass through the first channel 33 and enter between the first scraper blade 32 and the second scraper blade 42. The second scraper blade 42 cleans the remaining soil, and the soil then falls out of the punching device through the first channel 33.
[0046] like Figure 1 , Figure 2 As shown, in a further specific embodiment, the diameter of the pipe hole 111 is larger than the diameters of the first through hole 31 and the second through hole 41. This arrangement ensures that the soil is blocked by the second scraper 42 after passing through the first scraper 32, thereby allowing the soil to fall out of the drilling device through the pipe hole 111 and the first through groove 33 after being blocked by the second scraper 42.
[0047] See Figure 3 As shown, in a further specific embodiment, a plurality of connectors 5 are also included. The first end of the plurality of connectors 5 is connected to the first scraper plate 3, and the second end of the plurality of connectors 5 is connected to the second scraper plate 4. By setting the connectors 5, the first scraper plate 3 and the second scraper plate 4 are respectively set at both ends of the mounting plate 11. On the one hand, this reduces installation costs and enhances stability. On the other hand, it increases the distance between the first scraper plate 3 and the second scraper plate 4, so that the elasticity of the first scraper plate 32 and the second scraper plate 42 can be fully released without obstruction.
[0048] See Figure 1 , Figure 2 , Figure 5 As shown, in a further specific embodiment, the bottom of the perforated pipe 2 has at least one slit 21 along the axial direction. As a preferred embodiment, the number of slits 21 in this embodiment is three, and the three slits 21 are evenly distributed at the bottom of the perforated pipe 2. By setting the slits 21, the bottom of the perforated pipe 2 has a certain elasticity, so the soil in the soil can enter the perforated pipe 2 better. The structure is simple and the practicality is strong.
[0049] In other specific embodiments, the number of slits 21 can be two, four, or more, depending on the material of the perforated pipe 2 and the hardness of the soil. When the soil is hard and the material of the perforated pipe 2 is soft, the strength of the perforated pipe 2 is low. Although it can penetrate deep into the soil, the perforated pipe 2 is more easily worn. Therefore, the number of slits 21 in the perforated pipe 2 can be appropriately reduced, for example, to one or two slits 21, to strengthen the perforated pipe 2 and extend its service life. When the soil is soft and the material of the perforated pipe 2 is strong, the perforated pipe 2 can penetrate the soil more easily. Therefore, the number of slits 21 in the perforated pipe 2 can be appropriately increased to increase the elasticity of the bottom of the perforated pipe 2, making it easier to bring the soil out of the deep soil.
