Description

Technical Field

[0001] The utility model relates to the technical field of fallen leaf recycling equipment, in particular to a fallen leaf crushing and recycling device. Background Art

[0002] The statements herein only provide background art related to the utility model and do not necessarily constitute prior art.

[0003] The amount of fallen leaves, dead branches and withered grass in cities is very large. Taking a deciduous broad-leaved tree with a growth period of ten years as an example, the annual fallen leaves are about 500 kg (dry weight). The collection of fallen leaves mainly depends on sanitation workers arriving at work early every morning and continuously sweeping the leaves throughout the day. The work intensity of sanitation workers is high. The treatment methods of fallen leaves mainly include incineration, landfill and composting. Incineration will produce harmful gases and pollute the environment. Landfill will occupy land and cause waste of resources. Composting requires a long time and is prone to breeding bacteria. The existing fallen leaf treatment methods will cause waste of resources.

[0004] The prior art has the following technical problems:

[0005] The prior art combines the function of sucking in fallen leaves and the function of crushing them on one device to complete the collection and crushing of fallen leaves. For example, a kind of landscaping fallen leaf collection device with the application number 202122880010.7 combines a sucking component and spiral crushing teeth on a trolley to complete the collection and crushing of fallen leaves. However, when the fallen leaves of this device flow from the crushing teeth to the third exhaust fan, it is easy to be blocked at the outlet of the crushing area. Long-term blockage will cause the crushed fallen leaves to flow back. Summary of the Utility Model

Detailed implementation manners

[0026] The following combines with the attached drawings to illustrate the detailed implementation manners of this embodiment.

[0027] Refer to Figure 1 、 Figure 2 and Figure 3 For a fallen leaf crushing and recycling device, it includes a vertical pipe 1. The vertical pipe 1 vertically penetrates through the horizontal pipe 1-1. An absorption fan blade 3 is installed at the top end of the vertical pipe 1. A connecting shaft 12 is provided on the horizontal pipe 1-1. A blowing fan blade 4, a reamer 8 and a shunt fan 7 are successively and fixedly installed on the connecting shaft 12. The blowing fan blade 4 blows the conveying blades;

[0028] The connecting shaft 12 drives the blowing fan blade 4, the reamer 8 and the shunt fan 7 to rotate simultaneously, and the blowing fan blade 4 blows the conveying fan blade 6 to rotate.

[0029] A leaf suction port 10 is arranged at the bottom end of the vertical pipe. The leaf suction port 10 is set to be conical. The absorption port is made into a conical outer contour to increase the collection area of fallen leaves on the ground. The leaf suction port 10 is located below the recycling device and extends outside the vehicle.

[0030] The end of the horizontal pipe is connected to a hose 11-1, and a blowing outlet 11 is installed at the end of the hose 11-1.

[0031] The hose 11-1 adopts a steel wire telescopic hose 11-1. An existing polyurethane material steel wire telescopic hose 11-1 is used. The hose 11-1 at the blowing outlet 11 can be bent, and the inclination angle of the blowing outlet 11 can be freely adjusted to blow the shredded fallen leaves to different distances on the ground.

[0032] In this embodiment, after bending and adjusting the hose 11-1, the axis of the blowing outlet 11 is set perpendicular to the axis of the horizontal pipe 1-1.

[0033] The reamer 8 is arranged in a spiral shape along the axis of the connecting shaft 12. The type of the reamer 8 can be replaced according to the vehicle type, road conditions, environment and the nature of fallen leaves. The specific difference of the reamer 8 lies in the spiral density of the cutting edge and the sharpness of the cutting edge.

[0034] A support frame 9 is fixedly installed on the lower side wall of the horizontal pipe. An ear plate is installed at the end of the support frame 9, and a threaded hole is opened on the ear plate. The recycling device is installed on a mobile trolley through the support frame 9.

[0035] The axis of the shunt fan 7 is perpendicular to the axis of the connecting shaft 12. The shunt fan 7 is installed in the horizontal pipe 1-1 through the coupling shaft 13. The coupling shaft 13 is fixed to the side wall of the horizontal pipe 1-1. The shunt fan 7 is rotationally installed on the coupling shaft 13 through an existing bearing structure. The perpendicular setting of the shunt fan 7 ensures that the wind direction of the blowing fan blade 4 is parallel to the rotation plane of the shunt fan 7, avoiding the blockage of fallen leaves at the outlet and enabling the shredded fallen leaves to be sent out of the blowing outlet 11 in a timely manner.

[0036] A first motor 2 is provided at the upper end of the absorption fan blade 3, and the absorption fan blade 3 is controlled by the first motor 2.

[0037] A second motor 5 is provided on one side of the blowing fan blade 4, and the blowing fan blade 4 is controlled by the first motor 2.

[0038] The working principle is as follows:

[0039] The first motor 2 drives the absorption fan blade 3 to rotate to generate a negative pressure area, sucking the fallen leaves from the leaf suction port 10 through the vertical pipe 1 to the crushing area. When the fallen leaves reach the position of the reamer 8, they start to be crushed. To prevent the fallen leaves sucked into the reamer 8 from falling out of the leaf suction port 10, a blowing fan blade 4 is installed on the right side of the reamer 8 to blow the shredded leaves to the left shunt port in a timely manner. The reamer 8 can crush the fallen leaves to a uniform diameter of 2 cm to facilitate the decomposition of the fallen leaves. The shunt fan 7 timely shunts the shredded fallen leaves to avoid the blockage of shredded leaves at the shunt port. The conveying fan blade 6 installed on the left guides the shredded leaves to the blowing outlet 11 to prevent the shredded fallen leaves from flowing back. The bent part of the blowing outlet 11 is designed as a telescopic rigid hose 11-1, which can arbitrarily adjust the inclination angle of the blowing outlet 11. The shredded leaves are sent out of the crushing device and can be blown onto the roadside or collected.

[0040] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation on the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
