[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example
[0021] The leaf crushing and processing device described in this embodiment, such as Figures 1 to 5 As shown, the processing box 1 includes a detachable front sidewall. The front sidewall of the processing box 1 is detachably connected by screws. When disassembled, the internal components of the processing box 1 are installed.
[0022] A crushing cylinder 2 is fixed inside the processing box 1. The rear end of the crushing cylinder 2 is fixed to the rear inner side wall of the processing box 1. After the front side wall of the processing box 1 is installed, the front end of the crushing cylinder 2 is fixed to the front side wall of the processing box 1 by screws.
[0023] like Figure 1 , Figure 3 and Figure 4 As shown, a first rotating shaft 4 is located at the center of the crushing cylinder 2. Corresponding to the front and rear ends of the first rotating shaft 4, internal and external communicating mounting holes are provided on the front and rear side walls of the processing box 1. A first motor 17 is mounted on the rear side wall of the processing box 1. The rear end of the first rotating shaft 4 independently passes through the mounting hole located on the rear side and connects to the output end of the first motor 17. Several reamers with handles evenly spaced along its circumference are fixed on the first rotating shaft 4. This section constitutes a crushing assembly for crushing fallen leaves. In use, the first motor 17 drives the first rotating shaft 4 to rotate, and the first rotating shaft 4 drives the reamers to rotate, crushing the fallen leaves that enter the crushing cylinder 2.
[0024] A sleeve 14 is fitted on the first rotating shaft 4, and all the reamers 3 are fixed on the sleeve 14, which can realize the disassembly and connection between the reamers 3 and the sleeve 14, making it convenient to replace the damaged reamers 3; or five reamers 3 are fixed on each ring, and each five reamers corresponds to one sleeve 14, and several sleeves 14 are fitted on one first rotating shaft 4 in a sequence from front to back.
[0025] like Figure 1 and Figure 2As shown, the crushing cylinder 2 has a discharge port for discharging crushed fallen leaves. A detachable screen 5 is installed at the discharge port. The front side wall of the processing box 1 has a through groove that allows the screen 5 to pass through. The left and right sides of the discharge port have slots for inserting the screen 5. In use, the screen 5 is inserted into the processing box 1 through the through groove, with its left and right sides aligned with the slots on the left and right sides, and then inserted into the discharge port to complete the installation of the screen 5. A handle 15 is fixed to the front side of the screen 5 for easy removal or insertion.
[0026] like Figure 5 As shown, during use, the screen 5 can be replaced according to the size of its mesh openings. Once the fallen leaves are crushed to a size that can pass through the mesh, they are discharged from the screen 5. The degree of crushing of the leaves varies due to the obstruction of the screen 5. The specific screen mesh 5 should be selected according to actual needs.
[0027] A first guide plate 6 is fixed inside the processing box 1 directly below the screen 5. The first guide plate 6 has an inclined structure with the left side lower than the right side. A first discharge chute with internal and external communication is opened on the left side wall of the processing box 1. The broken leaves coming out of the screen 5 fall onto the first guide plate 6 and flow to the left side along the slope, and then are discharged from the first discharge chute.
[0028] A number of dividing rods 8 are fixed inside the processing box 1 on the right side of the crushing cylinder 2, arranged from front to back. A feed inlet with internal and external communication is opened on the left end of all the dividing rods 8. A blower that blows air towards the feed inlet is installed on the right side wall of the processing box 1. A feed trough with internal and external communication is opened on the top of the processing box 1.
[0029] like Figure 3 As shown, all the separators 8 are evenly spaced from front to back inside the processing box 1. The right end of all the separators 8 is fixed to the right inner side wall of the processing box 1. The separators 8 guide the fallen leaves to drift to the left, and the gravel falls between the separators 8. Some may even get stuck between two adjacent separators 8, but that doesn't matter. They can be treated uniformly later.
[0030] In use, turn on the blower, then put the fallen leaves into the feed chute. The leaves enter the processing chamber 1. Affected by the wind force of the blower, the lighter leaves drift to the left and enter the crushing cylinder 2 through the feed inlet to be crushed, while the heavier gravel is not affected by the wind speed and falls directly between the separator bars 8, thus separating the fallen leaves from the gravel. This product can not only separate fallen leaves and gravel, but also separate fallen leaves from some other heavier debris by weight, and these debris can affect the service life of the reamer 3.
[0031] Directly below all the dividing rods 8, a second guide plate 7 with a left-high, right-low tilt structure is fixed inside the processing box 1. A second discharge port with internal and external communication is opened on the right side wall of the processing box 1; the second discharge port is located below the blower. After falling from the dividing rods 8, gravel or other debris falls onto the second guide plate 7 and is discharged from the second discharge port along the slope.
[0032] The blower includes a fan housing 12, the air outlet of which is fixed to the right side wall of the processing box 1. An air inlet communicating with the air outlet is provided on the right side wall of the processing box 1. A second rotating shaft 11 is disposed inside the fan housing 12, and fan blades 10 evenly spaced along its circumference are fixed on the second rotating shaft 11. Through holes communicating with each other are provided on the front and rear side walls of the fan housing 12 corresponding to the front and rear ends of the second rotating shaft 11. A second motor 16, which drives the second rotating shaft 11 to rotate, is installed on the rear side wall of the fan housing 12. The second motor 16 drives the second rotating shaft 11 to rotate, generating airflow through the fan blades 10, which separates lighter fallen leaves and gravel through the air inlet.
[0033] A support rod 9 is fixed between the fan housing 12 and the right side wall of the processing box 1 to improve the stability of the fan housing 12 during installation.
[0034] A feed hopper 13 is fixed to the top of the processing box 1, and the feed hopper 13 is connected to the feed trough. The feed hopper 13 allows for the easy loading of a large amount of fallen leaves at once without them scattering.
[0035] The left end of the divider bar 8 is slightly bent upwards to stop debris that has a certain weight but will drift a distance with the wind.
[0036] In addition, under the action of wind, the fallen leaves at the separation point automatically enter the crushing cylinder 2, eliminating the need for manual transfer, reducing working steps and thus improving work efficiency.
[0037] In actual use, the collected fallen leaves are fed into the processing box 1 through the feeding chute. Under the action of the fan blades 10, the lighter fallen leaves are blown into the crushing cylinder 2, while the heavier gravel falls directly down. They are less affected by the wind force and are separated from the fallen leaves, thereby improving the separation effect of fallen leaves and gravel to a certain extent.
