Abstract

Disclosed is a leaf side-suction device for leaf cleaning, comprising a vertical air suction pipeline (1), an annular plate (2), and four knife arms (3) encircling a central axis of the annular plate (2), wherein a side face of each of the knife arms (3) in a horizontal direction is provided with a leaf suction strip-shaped hole (31), four leaf outlets (23) corresponding to the knife arms (3) are arranged in an inner face of the annular plate (2), each leaf outlet (23) communicates with the respective leaf suction strip-shaped hole (31), and a first channel is formed inside an annular arm and the knife arms (3); and an outside wall of the air suction pipeline (1) is attached to an inner wall of the annular plate (2). The problem of poor suction force is solved, and a hard pipeline and a hard suction opening are used so that a pump with a greater suction force can be used for collecting. A suction nozzle is laterally designed and sucks leaves from the side face. Since the thickness of leaves is very thin, the area of the opening is reduced effectively, and the suction force is increased effectively. There is no need to manually control the pipeline, which automatically rotates to sweep the leaves and suck same in, greatly saving on time and labour.

Description

Title of the invention: leaf cleaning device for leaf cleaning

Technical field

[0001] The present invention relates to a leaf side suction device for leaf cleaning.

Background technique

[0002] At present, the leaf picking device of the leaf collecting and cleaning vehicle is a large hose, and then the mouth of the hose is manually held and aligned with the leaves for suction. There are two problems with this. 1. Poor suction, the outer wall of the hose is soft, the suction pressure is small, and many kinds of leaves cannot be inhaled. 2. This method of vertical inhalation causes many garbage that is not leaves to be inhaled, and the suction nozzle is large when it is sucked vertically, that is, the area with the leaves is large, and the suction force is further reduced, which is not conducive to inhaling the leaves. 3, but also manually hold the straw, very hard.

[0005] The ring arm is provided with a ring of internal gears, and further comprises a driving motor. The power output end of the driving motor is connected with an external gear matched with the internal gear, and the external gear and the internal gear mesh; A plurality of universal wheels are arranged on the bottom surface of the annular disk.

[0006] Wherein, a bottom surface of each of the blade arms and a side of the hole of the suction blade are provided with a plurality of claws for hanging the leaves.

[0007] wherein the angle of the main suction port is greater than 90 degrees and less than 120 degrees. [0008] Therein, a strap arm for fixing the driving motor on the air suction duct is further included.

[0009] wherein a thrust bearing is disposed between the top surface of the tray and the bottom surface of the annular disk.

Advantageous effects of the invention

Beneficial effect

[0010] The problem of suction difference is solved, and a large suction pump can be used for collection due to the use of a hard pipe and a hard suction port. The nozzle is designed to be lateral, sucking the leaves from the side, and the thickness of the leaves is very thin, so that the area of the mouth can be effectively reduced, thereby effectively increasing the suction force. No need to manually control the pipe, automatically rotate the tree leaves and inhale, which is very labor-saving.

Embodiments of the invention

The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments, which are not intended to limit the scope of the invention.

[0018] As shown in FIG. 1 to FIG. 4,

[0019] Example 1.

[0020] The leaf side suction device for leaf cleaning according to the embodiment includes a vertical air suction duct 1, and further includes an annular disk 2, and further includes four arms disposed around the central axis of the annular disk 2. 3. One side of the horizontal direction of the arm 3 is provided with a suction hole 31, and the inner side of the annular disk 2 is provided with four corresponding to the arm 3. The outlet port 23, each of the outlet ports 23 communicates with the corresponding suction blade hole 31, and forms a first passage in the annular arm and the cutter arm 3; the outer wall of the suction duct 1 is fitted to the inner wall of the annular ratio; The tray 2 is sleeved with the bottom of the suction duct 1, and the bottom of the suction duct 1 is sealed with a tray 11 having a bottom surface abutting against the top surface of the tray 11; the bottom side of the suction duct 1 is provided with an outlet port 23 Corresponding main suction port 12;

[0021] The ring arm is provided with a ring internal gear 21, and further includes a driving motor 5, and a power output end of the driving motor 5 is connected with an external gear 51 coupled with the internal gear 21, an external gear 51 and The internal gear 21 meshes; and a plurality of universal wheels 22 are disposed on the bottom surface of the annular disk 2. A plurality of claws 32 for hanging leaves are provided on the bottom surface of each of the arms 3 and on the side of the suction hole 31.

[0022] The specific driving motor 5 drives the annular disk 2 to rotate, so that the four arms 3 also rotate, and the claws 32 collect the leaves. Since the suction hole 31 is a flat rectangle, the leaves can be sucked away side by side. When the annular disk 2 rotates, the time when the outlet port 23 of each of the arms 3 rotates to the main suction port 12 becomes suction, and the other does not have suction with the main suction port 12, and the suction power can be ensured; The universal wheel 22 is used for smoother rotation in contact with the ground. The present invention solves the problem of poor suction, which can be collected using a larger suction pump due to the use of a hard pipe and a hard suction port. The nozzle is designed to be lateral, sucking the leaves from the side, and the thickness of the leaves is very thin, so that the area of the mouth can be effectively reduced, thereby effectively increasing the suction force. No need to manually control the pipe, automatically rotate the leaves and inhale, which is very labor-saving.

[0023] In this embodiment, the angle of the main suction port 12 is greater than 90 degrees and less than 120 degrees. This arrangement is very scientific, preventing the two adjacent outlet ports 23 from forming a 90 degree angle, and the main suction port 12 does not have any intersection of the outlet ports 2 3 to form a negative pressure overload and damage the machine. If so set, the main suction port 12 will remain in communication with at least one of the outlet ports 23 at any moment.

[0024] In this embodiment, a strap arm 4 for fixing the drive motor 5 on the suction duct 1 is further included. In this embodiment, a thrust bearing is disposed between the top surface of the tray 11 and the bottom surface of the annular disk 2. Reduce the friction between the two and make the operation smoother.

[0025] Example 2.

[0026] The leaf side suction device may be placed on a specific vehicle to form a leaf collecting vehicle, the collecting vehicle includes a body body, the body body is provided with a suction pump and a leaf collecting frame, and the body body extends horizontally. The arm, the side of the mounting arm is equipped with a leaf side suction device, and the leaf side suction device is connected to the suction pump for sucking up the leaves. In this embodiment, the suction duct and the mounting arm are rotatably connected. Can change the main suction port 12 Angle, adapt to different roadside conditions.

The above description is only a preferred embodiment of the present invention, and equivalent changes or modifications made to the structures, features, and principles described in the scope of the present invention are included in the scope of protection of the present patent application.
