Description

Technical Field

[0001] The present disclosure relates to the technical field of sanitation tools, and in particular to a sweeper. Background Art

[0002] Roads in northern China are often lined with broadleaf trees. During autumn and winter, or during strong winds, the roads often become covered in leaves and branches. Sweepers are essential equipment for urban sanitation and cleaning. To ensure clean roads, they are often used to clear these leaves and branches.

[0003] Because broad-leaved trees have large leaves and branches of various shapes, when a road sweeper is used for cleaning, the leaves and branches cannot enter the suction nozzle smoothly, and accumulate at the entrance of the suction nozzle, or "block the pipe" occurs after entering the suction nozzle, which brings great trouble to the cleaning work of the road sweeper. Summary of the Invention

[0004] The purpose of the present disclosure is to provide a sweeper to solve the technical problem that leaves and branches are easily blocked in the suction nozzle of the sweeper.

[0005] In order to achieve the above-mentioned objectives, the present disclosure provides a sweeper, comprising: a suction nozzle, a cleaning device, which is arranged on the right side of the sweeper and is detachably connected to the body of the vehicle, the cleaning device comprising: a suction mechanism, which is fluidically connected to the suction nozzle of the sweeper; a first crushing mechanism, which is arranged at the front of the suction mechanism; and a sweeping disc mechanism, which is arranged on the side of the first crushing mechanism away from the longitudinal axis of the sweeper, the sweeping disc mechanism being constructed as a disc-shaped structure and capable of rotating close to the ground, and a second crushing mechanism, which is arranged at the front of the suction nozzle and located on the longitudinal axis of the sweeper.

[0006] Optionally, the cleaning device also includes a posture adjustment mechanism, which includes: a fixed arm, detachably connected to the cleaning vehicle; a movable arm, connected between the fixed arm and the first crushing mechanism, and the movable arm can be rotated relative to the fixed arm toward the outside or inside of the cleaning vehicle so that the first crushing mechanism can approach or move away from the longitudinal axis; and a first driving member, used to push the movable arm to rotate relative to the fixed arm.

[0007] Optionally, a base is provided on the upper surface of the first crushing mechanism, the base can rotate in a horizontal plane, the movable arm is connected to the base so as to rotate up and down, and the posture adjustment mechanism also includes a retractable first adjustment rod, which is provided between the movable arm and the base to drive the first crushing mechanism to rotate up and down by telescoping.

[0008] Optionally, the suction mechanism and the suction nozzle are sealed and connected via a hose.

[0009] Optionally, the cleaning device also includes a first mounting bracket fixedly connected to the first crushing mechanism, the sweeping disc mechanism is connected to the first mounting bracket so as to be rotatable up and down, and a retractable second adjusting rod is connected between the sweeping disc mechanism and the first mounting bracket to drive the sweeping disc mechanism to rotate up and down by the retraction of the second adjusting rod.

[0010] Optionally, the first crushing mechanism includes: a shell; a movable knife group rotatably arranged in the shell, the movable knife group including a plurality of movable blades; and a fixed knife group fixedly connected to the shell, the fixed knife group including a plurality of fixed blades; wherein the movable blades and the fixed blades are arranged in an alternating manner.

[0011] Optionally, the second pulverizing mechanism has the same structure as the first pulverizing mechanism.

DETAILED DESCRIPTION

[0026] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0027] In this disclosure, unless otherwise specified, directional terms such as "up, down, left, and right" generally refer to the up, down, left, and right of the sweeper in normal driving conditions, and "inside and outside" refer to the inside and outside relative to the outline of the corresponding component itself. The terms "first" and "second" used in this disclosure are intended to distinguish one element from another and do not have a sense of order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0028] According to a specific embodiment of the present disclosure, a sweeper is provided, referring to Figures 1 to 7 As shown, the road sweeper includes a suction nozzle 3, a cleaning device 1, and a second crushing mechanism 21. The cleaning device is arranged on the right side of the road sweeper and is detachably connected to the vehicle body. The second crushing mechanism 21 is arranged in front of the suction nozzle 3 and is located on the longitudinal axis of the road sweeper. As the road sweeper moves, the cleaning device 1 and the second crushing mechanism 21 can cooperate with the suction nozzle 3 to sweep the fallen leaves on the road. Figure 1 and Figure 3 As shown, the cleaning device 1 may include a suction mechanism 11, a first crushing mechanism 12 and a sweeping disc mechanism 13, wherein the suction mechanism 11 is in fluid communication with the suction nozzle 3, and the negative pressure generated by the suction nozzle 3 can be transmitted to the suction mechanism 11, so that the fallen leaves on the road surface can flow and gather toward the suction mechanism 11, and the first crushing mechanism 12 is arranged in front of the suction mechanism 11. Since the fallen leaves are mostly concentrated on the roadside, the sweeping disc mechanism 13 can be arranged on the side of the first crushing mechanism 12 away from the longitudinal axis of the sweeper, that is, the sweeping disc mechanism 13 is arranged on the rightmost side of the sweeper. The sweeping disc mechanism 13 can be constructed as a disc-shaped structure and can rotate close to the ground to sweep the fallen leaves toward the first crushing mechanism 12. In addition, the cleaning device 1 can be detachably mounted on the vehicle body through a connecting portion, which can be the fixed arm 141 described below. The fixed arm 141 can be detachably connected to the longitudinal beam 4 of the sweeper through a fastener 5, and the hydraulic pipelines can be connected through a quick connector.

[0029] Through the above technical solution, the suction nozzle 3 of the cleaning vehicle provided by the present disclosure can cause nearby leaves to flow toward the suction nozzle 3. Before the leaves enter the suction nozzle 3, they can first flow through the second crushing mechanism 21 and be cut into smaller pieces before entering the suction nozzle 3 to avoid clogging the suction nozzle 3. Since the suction mechanism 11 of the cleaning device 1 is fluidically connected to the suction nozzle 3, the suction mechanism 11 can cause leaves near the cleaning device 1 to flow toward the suction mechanism 11. Since the first crushing mechanism 12 is provided at the front of the suction mechanism 11, before entering the suction mechanism 11, the leaves can first pass through the first crushing mechanism 12 and be crushed into smaller pieces. They are then sucked into the garbage collection box provided in the cleaning vehicle, thereby avoiding clogging caused by large leaves directly entering the suction mechanism 11. The sweeping disc mechanism 13 provided on the far right side of the cleaning vehicle can sweep fallen leaves concentrated on the roadside toward the first crushing mechanism 12, thereby improving the cleaning efficiency of the cleaning vehicle. The second crushing mechanism 21 disposed on the longitudinal axis of the sweeper and the cleaning device 1 disposed on the right side of the sweeper cooperate with each other to clean fallen leaves directly in front of and to the right of the sweeper, thereby increasing the sweeping range of the sweeper and improving the working efficiency of the sweeper. In addition, since the cleaning device 1 can be detachably connected to the vehicle body, the cleaning device 1 can be installed on the sweeper (e.g., a washing sweeper or a dry sweeper) in seasons with heavy leaf fall, and can be removed in seasons with less fallen leaves. This allows the sweeper to adapt to both the leaf-clearing road conditions of spring and autumn and normal road sweeping operations.

[0030] The cleaning device 1 may further include a posture adjustment mechanism, see Figures 1 to 3 as well as Figure 5 and Figure 6 As shown, the posture adjustment mechanism may include a fixed arm 141, a movable arm 142 and a first driving member 143, wherein the fixed arm 141 may be connected to the longitudinal beam 4 of the sweeper by a fastener 5 and extend toward the first crushing mechanism 12, and the movable arm 142 is connected between the fixed arm 141 and the first crushing mechanism 12. Specifically, the movable arm 142 is connected to the end of the fixed arm 141 close to the first crushing mechanism 12, and the movable arm 142 can rotate in the horizontal plane to rotate toward the outside or inside of the sweeper relative to the fixed arm 141, thereby driving the first crushing mechanism 12 close to or away from the longitudinal axis to adjust the cleaning range of the cleaning device 1. The first driving member 143 may be a cylinder, and the output end of the cylinder is connected to the movable arm 142 to push the movable arm 142 to rotate relative to the fixed arm 141.

[0031] In order to make the first crushing mechanism 12 always face the front of the sweeper, refer to Figure 1 and Figure 5As shown, the upper surface of the first pulverizing mechanism 12 is provided with a base 15 that can rotate within a horizontal plane. A movable arm 142 is connected to the base 15 so as to be rotatable up and down. When the movable arm 142 rotates toward the outside or inside of the sweeper, the movable arm 142 not only drives the base 15 toward or away from the longitudinal axis of the sweeper, but also drives the base 15 to rotate within the horizontal plane. Because the base 15 can rotate within the horizontal plane relative to the first pulverizing mechanism 12, the first pulverizing mechanism 12 can only translate in a direction toward or away from the longitudinal axis of the sweeper, preventing the first pulverizing mechanism 12 from rotating left or right with the movable arm 142, thereby ensuring that the first pulverizing mechanism 12 always faces directly in front of the sweeper. The posture adjustment mechanism may also include a retractable first adjustment rod 144, which is disposed between the movable arm 142 and the base 15 to drive the first pulverizing mechanism 12 to rotate up and down by retracting. The first adjustment rod 144 may include a screw structure to achieve retraction and extension of the first adjustment rod 144 through a threaded connection. Since the base 15 can rotate up and down relative to the movable arm 142, when the first adjustment rod 144 is extended or retracted, the base 15 can drive the first crushing mechanism 12 to rotate up and down, thereby adjusting the angle between the first crushing mechanism 12 and the ground. In other words, the pitch of the first crushing mechanism 12 can be adjusted by extending or retracting the first adjustment rod 144.

[0032] To enable relative rotation between the base 15 and the first pulverizing mechanism 12 within a horizontal plane, a vertically extending rotational shaft may be connected between the base 15 and the upper surface of the first pulverizing mechanism 12, about which the base 15 can rotate. The rotational shaft may be configured as a first bolt. Furthermore, to limit the rotational angle of the base 15, a second and third vertically extending bolt may be connected between the base 15 and the upper surface of the first pulverizing mechanism 12. The rotational shaft, the second and third bolts may be arranged in a triangular shape, with the base 15 fixedly connected to the second and third bolts. Waist-shaped holes are provided on the upper surface of the first pulverizing mechanism 12 at positions corresponding to the second and third bolts. When the base 15 rotates relative to the first pulverizing mechanism 12 within a horizontal plane, the second and third bolts can slide within their corresponding waist-shaped holes, thereby limiting the rotational angle of the base 15.

[0033] refer to Figure 5 and Figure 6 The suction mechanism 11 can be sealed and connected to the suction nozzle 3 of the sweeper through a hose. When the first crushing mechanism 12 drives the suction mechanism 11 to rotate up and down or translate in a direction close to or away from the longitudinal axis of the sweeper, the hose can be deformed with the movement of the suction mechanism 11 to ensure that the suction mechanism 11 and the suction nozzle 3 are always sealed and connected.

[0034] In order to adjust the angle between the sweeping disc mechanism 13 and the ground, refer to Figures 1 to 3as well as Figure 5 and Figure 6 As shown, the leaf shredder 1 may further include a first mounting bracket 16 fixedly connected to the first shredder mechanism 12. The sweeping disc mechanism 13 is rotatably connected to the first mounting bracket 16. A retractable second adjustment rod 17 is connected between the sweeping disc mechanism 13 and the first mounting bracket 16 to drive the sweeping disc mechanism 13 to rotate up and down by extending and retracting the second adjustment rod 17. The second adjustment rod 17 may include a screw structure to achieve extension and retraction of the second adjustment rod 17 through a threaded connection. When the second adjustment rod 17 is extended or retracted, the sweeping disc mechanism 13 can be rotated up and down relative to the first mounting bracket 16, thereby adjusting the pitch of the sweeping disc mechanism 13.

[0035] In addition, reference Figure 2 As shown, the first crushing mechanism 12 may include a shell 121, a movable knife group and a fixed knife group. The movable knife group is rotatably arranged in the shell 121. The movable knife group may include a rotating shaft and a plurality of movable blades 122 arranged on the rotating shaft. The shell 121 may be provided with a motor for driving the rotating shaft to rotate. The fixed knife group is fixedly connected to the shell 121. The fixed knife group may include a plurality of fixed blades 123, wherein the movable blades 122 and the fixed blades 123 are arranged in an staggered manner. When the movable blades 122 rotate with the rotating shaft, they can cooperate with the fixed blades 123 to cut the leaves.

[0036] In order to adjust the angle between the second crushing mechanism 21 and the ground, refer to Figure 4 As shown, the suction nozzle 3 is provided with a second mounting bracket 22, and the second pulverizing mechanism 21 is connected to the second mounting bracket 22 so as to be rotatable up and down. The second pulverizing mechanism 21 and the suction nozzle 3 are connected by a retractable third adjustment rod 23, so that the second pulverizing mechanism 21 is driven to rotate up and down by the extension and retraction of the third adjustment rod 23. The third adjustment rod 23 may include a screw structure to achieve the extension and retraction of the third adjustment rod 23 through a threaded connection. When the third adjustment rod 23 is extended or retracted, the second pulverizing mechanism 21 can be rotated up and down relative to the second mounting bracket 22, thereby adjusting the pitch of the second pulverizing mechanism 21.

[0037] In addition, reference Figure 7 As shown, a baffle 6 capable of rotating up and down may be provided between the suction nozzle 3 and the second pulverizing mechanism 21. The baffle 6 is connected to the suction nozzle 3, and a second driving member 7 is provided between the suction nozzle 3 and the baffle 6 to drive the baffle 6 to rotate up and down. The second driving member 7 may be a cylinder. When the suction nozzle 3 is in operation, the second driving member 7 can drive the baffle 6 to rotate upward, thereby opening the feed opening of the suction nozzle 3. When the suction nozzle 3 is not sucking or the second pulverizing mechanism 21 is not in operation, the second driving member 7 can drive the baffle 6 to rotate downward, thereby closing the feed opening of the suction nozzle 3 to prevent the suction nozzle 3 from being blocked.
