[0016] like Figure 1-Figure 2 As shown, a leaf composting device for landscaping includes a support platform 1, two vertical mounting plates 2 are symmetrically fixedly arranged at one end of the support platform 1, a screw rod 3 is rotatably installed between the two vertical mounting plates 2, and a first motor 4 for driving the screw rod 3 to rotate is installed on the outer side of one of the vertical mounting plates 2. A moving platform 5 is arranged on the screw rod 3, and a threaded hole matching the screw rod 3 is opened in the middle of the moving platform 5. In addition, two guide slide bars 6 are symmetrically fixedly installed between the two vertical mounting plates 2 along the screw rod 3, and two light holes are opened on the moving platform 5 to slide with the two guide slide bars 6 respectively.

[0017] A support frame 7 is fixedly provided on the upper part of the mobile platform 5, and a crushing box 8 with an open structure on the upper part is fixedly provided on the support frame 7. Two crushing shafts 9 are rotatably installed in the crushing box 8 near the upper end, and a second motor 10 for driving the two crushing shafts 9 to rotate relative to each other is installed on the outside of the crushing box 8, and multiple groups of crushing blades 11 are staggered on the two crushing shafts. In this embodiment, the driving shaft of the second motor 10 is connected to one end of one of the crushing shafts 9, and the ends of the two crushing shafts 9 away from the second motor extend to the outside of the crushing box 8 respectively and are provided with two mutually meshing gears 12 at the ends. When the second motor 10 drives the corresponding crushing shaft 9 to rotate, the two crushing shafts 9 are driven to rotate relative to each other through the transmission action of the two gears 12.

[0018] The bottom of the crushing box 8 is connected to the feeding port of the auger conveyor 14 through the material guide channel 13. The material guide channel 13 is made of thickened steel plate and is welded and fixed to the crushing box 8 and the auger conveyor 14 respectively. While connecting the crushing box 8 and the auger conveyor 14, it also plays the role of fixing the two. The auger conveyor 14 is arranged upwardly and tilted away from the crushing box 8, and its discharge port faces downward.

[0019] A fermentation barrel 15 is fixedly installed at the other end of the support platform 1. Specifically, two horizontal support plates 16 are symmetrically fixedly installed on the support platform 1 near the two sides of the fermentation barrel 15. A connecting ring 17 is fixedly installed on the outer wall of the fermentation barrel 15. The connecting ring 17 is fixedly connected to the two support plates 16 through two groups of symmetrical bolt groups, thereby realizing the detachable connection of the fermentation barrel 15 on the support platform 1. A heating chamber 18 with a circular cross section is arranged in the peripheral wall of the fermentation barrel 15, and an electric heating wire 19 is wound and installed in the heating chamber 18. In addition, a heat preservation layer 20 is sleeved on the outer peripheral wall of the fermentation barrel 15.

[0020] The support platform 1 is fixedly provided with a horizontal mounting plate 21 on the outside of the fermentation cylinder 15, and a vertical driving cylinder 22 is installed on the horizontal mounting plate 21. The telescopic end of the driving cylinder 22 is fixedly connected to one end of a horizontal lifting platform 23, and a sealing cover 24 matching the opening of the fermentation cylinder 15 is fixedly provided at the lower part of the other end of the lifting platform 23 at a position directly facing the fermentation cylinder 15. A third motor 25 is installed on the upper part of the lifting platform 23, and the driving shaft of the third motor 25 passes through the lifting platform 23 and the sealing cover 24 and is connected to the stirring shaft 26, and a stirring assembly is provided on the peripheral wall of the stirring shaft 26.

[0021] In this embodiment, the stirring assembly includes two groups of stirring rods 27 symmetrically fixed on the stirring shaft 26, and the outer sides of each group of stirring rods 27 are fixedly connected to the scraper 28. When the stirring shaft 26 enters the interior of the fermentation cylinder 15, the two scrapers 28 contact the inner wall of the fermentation cylinder.

[0022] The working mode of the utility model is as follows:

[0023] Before work, the first motor drives the screw to rotate, so that the mobile platform moves toward the fermentation barrel until the discharge port of the auger conveyor is located above the fermentation barrel. The staff puts the collected garden greening leaves into the crushing box from the upper opening end of the crushing box, and the second motor drives the two crushing shafts to rotate. The crushing blades staggered on the two crushing shafts crush the leaves. The fallen leaf fragments enter the auger conveyor from the lower part of the crushing box through the material guide channel, and are transported to the fermentation barrel by the auger conveyor to complete the automatic feeding.

[0024] When the feeding is completed, the first motor drives the screw to rotate in the opposite direction, so that the mobile platform moves away from the fermentation cylinder until the upper half of the auger conveyor deviates from the fermentation cylinder. After the staff puts the fermentation liquid required for compost production into the fermentation cylinder, the driving cylinder contracts, causing the lifting platform to move downward until the sealing cover at the bottom of the lifting platform completely covers the upper opening of the fermentation cylinder. The electric heating wire inside the heating chamber is energized to ensure the fermentation temperature required for composting inside the fermentation cylinder. The third motor is started regularly to rotate the stirring shaft, and the stirring assembly stirs the fallen leaf compost inside the fermentation cylinder to ensure that the fallen leaf fragments are fermented evenly.

[0025] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
