Description

Technical Field

[0001] This utility model relates to the field of lawn trimming technology, specifically a convenient and extendable lawn trimming machine. Background Technology

[0002] Artificial turf is a chemical product that combines the properties of natural grass with synthetic fibers resembling grass leaves embedded in a woven base fabric and coated on the back with a fixation layer. After a period of use, artificial turf tends to develop long, bushy fibers, requiring regular trimming. Patent CN218711938U discloses a double-sided turf trimming machine. In operation, the turf enters from the bottom left side of the casing, then passes around the bottommost guide roller and the topmost guide roller before exiting from the top right side of the casing. The three guide rollers help keep the turf between them vertical. The turf between the two bottom guide rollers is first heated by a heating plate to dry the soil on the turf. Then, with the traction mechanism, the turf continues to... Moving upwards, the dry soil on the lawn is knocked off by the striking mechanism. The lawn then continues to move upwards to between the two guide rollers on the upper side, where it is trimmed by the trimming mechanisms on both sides. At this point, the lawn is vertically positioned between the two trimming mechanisms, and the center of gravity of the lawn does not affect the trimming, making it easier to trim the lawn evenly on both sides. The lawn is also cleaned before cleaning. However, the process requires pulling the laid lawn up from the ground and then laying it back down, which is laborious and slow. Therefore, a portable, extendable lawn trimmer is designed to cut and trim the lawn directly from the top, which is convenient to operate, increases the trimming speed, and facilitates the recycling of the trimmed fibers.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1-7 A portable, extendable lawn trimmer includes a mobile cart. The bottom of the mobile cart is equipped with an extendable sliding cover 4 that can be extended vertically. The bottom of the extendable sliding cover 4 is equipped with a trimming structure. The rear side of the bottom of the extendable sliding cover 4 is equipped with an adjustable lawn comb 10. The top of the mobile cart is equipped with a trimming and recovery structure that communicates with the top of the extendable sliding cover 4.

[0026] Specifically, the turf trimming structure includes a rotating shaft 6 rotatably connected to the bottom of the telescopic sliding cover 4, with a spiral cutting belt 7 fixedly mounted on the rotating shaft 6. The telescopic sliding cover 4 and the moving frame slide and lift together. It also includes a drive mechanism for driving the rotating shaft 6 to rotate. Furthermore, the drive mechanism includes a drive motor 8 fixedly mounted on the top rear side of the telescopic sliding cover 4. The output shaft of the drive motor 8 is connected to the rotating shaft 6 via a transmission assembly 9. Furthermore, the transmission assembly 9 can be configured as a sprocket and chain or a transmission wheel and belt. Activating the drive mechanism facilitates the rotation of the rotating shaft 6 and the spiral cutting belt 7 as a whole, allowing the turf fibers to be trimmed via the spiral cutting belt 7.

[0027] Specifically, it also includes a telescopic drive cylinder 5 that is vertically fixed on the mobile vehicle. The bottom output shaft of the telescopic drive cylinder 5 is fixedly connected to the top of the telescopic sliding cover 4. Through the telescopic drive cylinder 5, the telescopic sliding cover 4 can be easily moved up and down, thereby adjusting the distance between the trimming structure and the lawn, and thus facilitating the adjustment of the trimming length.

[0028] Specifically, the top of the lawn comb 10 is fixedly installed with a lifting bar 11 that slides and moves with the telescopic cover 4. Above the lifting bar 11 is a fixing bar 12 that is fixedly connected to the telescopic cover 4. The fixing bar 12 is vertically threaded with a lifting screw 13 that is rotatably connected to the bottom of the lifting bar 11. An adjustment knob is fixedly installed on the top of the lifting screw 13. By rotating the adjustment knob, the lifting screw 13 can be rotated, thereby driving the fixing bar 12 and the lawn comb 10 to move up and down as a whole, thereby adjusting the sprucing height.

[0029] Specifically, the lint collection and recovery structure includes a receiving box 14 and an exhaust fan 15 located on top of the mobile frame. The receiving box 14 is divided into a lint collection side and a flow side. The lint collection side is equipped with a lint collection hopper 21, and a filter screen 22 is installed facing the flow side of the lint collection hopper 21. The top of the lint collection side is fixedly connected to the top of the telescopic sliding cover 4 via a telescopic tube 17. The input end of the exhaust fan 15 is connected to the flow side via an exhaust pipe 19 and extends to the bottom of the flow side. When the exhaust fan 15 is activated, the telescopic sliding cover 4 draws the cut lint and debris back to the lint collection side through the telescopic tube 17, then through the filter screen 22 into the flow side, and finally through the exhaust pipe 19 at the bottom. Due to the installation of the exhaust pipe 19 and the filter screen 22, the lint is concentrated at the bottom of the lint collection hopper 21, thus facilitating the collection of lint within the lint collection hopper 21. The lint and debris are cleaned up. Furthermore, the telescopic tube 17 includes a telescopic tube 17 with an upper connecting tube 18 and a lower connecting tube 16 fixedly connected to its top and bottom, respectively. The bottom of the lower connecting tube 16 is vertically slidably engaged with the moving frame and is fixedly connected to the top of the telescopic sliding cover 4. The free end of the upper connecting tube 18 is fixedly connected to the top of the lint collection side. Furthermore, the flow side is provided with a partition frame 20 that slides and guides the lint collection hopper 21, facilitating the pushing in and pulling out of the partition frame 20. Furthermore, multiple spare collection hoppers 21 can be placed on the upper rear side of the moving frame, facilitating direct replacement after the collection hopper 21 is full, avoiding the need to remove it from the lawn for unloading, and further improving the lint cutting effect. Furthermore, the exhaust fan 15 can be fixedly installed on the top of the collection box 14.

[0030] Specifically, the mobile vehicle includes a support frame 1 with multiple rollers 2 installed at the bottom. A push rod 3 is fixedly installed on the top rear side of the support frame 1. The push rod 3 facilitates manual pushing, and the multiple rollers 2 facilitate pushing the device on the lawn to trim the lawn.
