Description

Technical Field

[0001] This utility model relates to the field of road sweeping technology, specifically a towed self-rotating shoulder sweeper. Background Technology

[0002] The shoulder refers to the strip-shaped section of a certain width located from the outer edge of the carriageway to the edge of the roadbed. In order to maintain the function of the carriageway and for temporary parking, and to serve as lateral support for the road surface, a lot of debris and garbage often accumulates on the shoulders and edges of the road. In order to keep the road surface clean, it is necessary to clean the garbage on the shoulders and edges regularly.

[0003] In existing technologies, workers typically sweep road shoulders and edges with hand brooms or drive road sweepers. However, in practice, manual sweeping is slow, requires bending over and repetitive movements, leading to fatigue. This significantly increases manpower consumption when working on large areas, and prolonged work in dusty environments is detrimental to workers' health. Furthermore, road sweepers are expensive to purchase, placing a heavy burden on small and medium-sized road maintenance units. Since road sweepers involve engines, hydraulic systems, and electrical controls, maintenance and repair are also costly. Therefore, there is a need to develop a towed, self-rotating road shoulder sweeper to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a towed self-rotating shoulder sweeper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a towed self-rotating shoulder sweeper, comprising a connecting frame, a traction frame fixedly installed on the back of the connecting frame, a first support frame fixedly installed on the top of the connecting frame, a support rod fixedly installed on the back of the connecting frame, a support wheel fixedly installed at the bottom of the support rod, a sweeping mechanism provided on the outside of the connecting frame, and a limit mechanism provided on the outside of the connecting frame.

[0006] Preferably, the sweeping mechanism includes an extension rod, which is fixedly installed on the front of the connecting frame. A first rotating rod is rotatably installed inside the extension rod, and a movable wheel is fixedly installed on the outside of the first rotating rod. A chain is installed on the left end of the first rotating rod via a sprocket drive. A support base is fixedly installed at the bottom of the connecting frame, and a second rotating rod is rotatably installed inside the support base. The left end of the second rotating rod is installed via a sprocket drive and a chain drive. A second support frame is fixedly installed on the inner wall of the first support frame. A first brush roller is fixedly installed on the outside of the second rotating rod, and a second brush roller is fixedly installed on the outside of the second rotating rod, facilitating the sweeping of road shoulders and curbs.

[0007] Preferably, a through hole is provided at the corresponding position of the second support frame and the second rotating rod, the second rotating rod passes through the through hole, and the second rotating rod is rotatably installed with the second support frame through a bearing, which facilitates the smooth rotation of the second rotating rod.

[0008] Preferably, the limiting mechanism includes a collection hopper, which is rotatably installed inside a connecting frame. A screw is rotatably installed on the front side of the connecting frame, and a limiting rod is fixedly installed on the front side of the connecting frame. A connecting frame is installed on the external thread of the screw, and a roller is rotatably installed inside the connecting frame to facilitate the collection of waste.

[0009] Preferably, the connecting frame has a through hole at the position corresponding to the limiting rod, and the limiting rod is slidably installed in the through hole to facilitate the limiting operation of the connecting frame.

[0010] Compared with the prior art, this utility model provides a towed self-rotating shoulder sweeper, which has the following beneficial effects:

[0011] 1. This towed self-rotating shoulder sweeper, through its cleaning mechanism, utilizes an extension rod to facilitate the support and rotation of the first rotating rod during operation. The support base and second support frame work together to support the second rotating rod. The moving wheels facilitate the traction and movement of the connecting frame. The sprockets and chain facilitate the rotation of the first and second brush rollers, thus facilitating the cleaning of the roadside and shoulder sides. The rotation of the moving wheels drives the first and second brush rollers, eliminating the need for a separate power supply or hydraulic transmission device. This results in low purchase costs, a simple equipment structure, and low maintenance costs. Furthermore, the connecting frame can be moved by any vehicle towing it, requiring minimal manpower.

[0012] 2. This towed self-rotating shoulder sweeper, through its set limiting mechanism, allows the rotating collection bucket to easily contact the ground during use, thus facilitating the sweeping of garbage into the collection bucket's interior. After the sweeping work is completed, the collection bucket is rotated to remove it from contact with the ground. By rotating the screw, in conjunction with the limiting rod, the connecting frame moves, causing the rollers to contact the inner wall of the collection bucket. This facilitates the limiting of the rotated collection bucket, ensuring smooth subsequent movement of the connecting frame and preventing garbage leakage from the collection bucket.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example 1:

[0023] Please see Figures 1-4 This utility model provides a technical solution: a towed self-rotating shoulder sweeper, including a connecting frame 1, a traction frame 2 fixedly installed on the back of the connecting frame 1, which facilitates the connection between the vehicle and the traction frame 2, and facilitates the traction and movement of the connecting frame 1. A first support frame 3 is fixedly installed on the top of the connecting frame 1, a support rod 4 is fixedly installed on the back of the connecting frame 1, a support wheel 5 is fixedly installed at the bottom of the support rod 4, a sweeping mechanism 6 is provided on the outside of the connecting frame 1, and a limit mechanism 7 is provided on the outside of the connecting frame 1.

[0024] Furthermore, the cleaning mechanism 6 includes an extension rod 601, which is fixedly installed on the front of the connecting frame 1. A first rotating rod 602 is rotatably mounted inside the extension rod 601. There are two extension rods 601 to provide stable support for the first rotating rod 602. Two movable wheels 603 are fixedly mounted on the outside of the first rotating rod 602, symmetrically arranged outside the first rotating rod 602. A chain 604 is mounted on the left end of the first rotating rod 602 via a sprocket drive. A support base 605 is fixedly installed at the bottom of the connecting frame 1. A second rotating rod 606 is rotatably mounted inside the support base 605. The left end is driven by a sprocket and chain 604. A second support frame 607 is fixedly installed on the inner wall of the first support frame 3. A first brush roller 608 and a second brush roller 609 are fixedly installed on the outside of the second rotating rod 606. As the connecting frame 1 moves, the first brush roller 608 and the second brush roller 609 are always in contact with the ground. When cleaning the roadside and shoulder, the movement of the vehicle causes the moving wheel 603 and the first rotating rod 602 to rotate. With the cooperation of the sprocket and chain 604, the second rotating rod 606 rotates, thereby causing the first brush roller 608 and the second brush roller 609 to rotate and clean up the garbage.

[0025] Furthermore, the second support frame 607 and the second rotating rod 606 are provided with through holes at corresponding positions. The second rotating rod 606 passes through the through holes and is rotatably mounted to the second support frame 607 via bearings, which facilitates the smooth rotation of the second rotating rod 606 and thus ensures the smooth rotation of the first brush roller 608 and the second brush roller 609.

[0026] Please see Figure 5Furthermore, in conjunction with Embodiment 1, the limiting mechanism 7 includes a collecting hopper 701, which is rotatably mounted inside the connecting frame 1. A screw 702 is rotatably mounted on the front of the connecting frame 1, and a polygonal block is fixedly mounted on the front of the screw 702 to facilitate manual rotation of the screw 702. A limiting rod 703 is fixedly mounted on the front of the connecting frame 1. A connecting frame 704 is threaded onto the external of the screw 702, and a roller 705 is rotatably mounted inside the connecting frame 704. As the collecting hopper 701 comes into contact with the ground, the roller 705 no longer interacts with the collecting hopper. When the collection hopper 701 comes into contact, the connecting frame 704 moves by rotating the screw 702, causing the roller 705 to move away from the inner wall of the collection hopper 701, thus bringing the collection hopper 701 into contact with the ground. This facilitates the subsequent sweeping of garbage into the collection hopper 701. After the cleaning work is completed, the collection hopper 701 is rotated so that it is no longer in contact with the ground. By rotating the screw 702 in the opposite direction, the roller 705 comes into contact with the inner wall of the collection hopper 701, thus limiting the rotation of the collection hopper 701 and preventing garbage leakage.

[0027] Furthermore, a through hole is provided inside the connecting frame 704 at the position corresponding to the limiting rod 703, and the limiting rod 703 is slidably installed in the through hole, which facilitates the limiting operation of the connecting frame 704, thereby ensuring the smooth movement of the connecting frame 704 and the roller 705.

[0028] In actual operation, when this device is used, it is connected to the vehicle hook via the traction frame 2. When cleaning the roadside and shoulder, the connecting frame 704 is moved by rotating the screw 702, causing the roller 705 to move away from the inner wall of the collection hopper 701, thus bringing the collection hopper 701 into contact with the ground. As the vehicle moves, the moving wheel 603 and the first rotating rod 602 rotate. With the cooperation of the sprocket and chain 604, the second rotating rod 606 rotates, causing the first brush roller 608 and the second brush roller 609 to rotate, sweeping the garbage into the inside of the collection hopper 701. After the cleaning work is completed, the collection hopper 701 is rotated so that it is no longer in contact with the ground. By rotating the screw 702 in the opposite direction, the roller 705 contacts the inner wall of the collection hopper 701, limiting the rotation of the collection hopper 701 and preventing the garbage from leaking out.
