Description

Technical Field

[0001] This utility model belongs to the field of environmental sanitation technology, and in particular relates to a towed road sweeper. Background Technology

[0002] A towed sweeper is a non-powered sweeping device that needs to be towed by a tractor or truck, specifically designed for large open areas. Its core working principle involves rotating side brushes collecting debris, which is then swept up by the main brush and thrown into a built-in garbage bin. Some high-end models are also equipped with a dust collection system for dry sweeping. The main advantages of this equipment are its extremely high cost-effectiveness and operating efficiency. Because it does not require a chassis, its purchase cost is far lower than that of a self-propelled sweeper, and it can sweep a wide area. However, towed sweepers still have the following drawbacks in practical use: During the sweeping process, the towed sweeper directly transports the garbage into its built-in garbage bin. However, the capacity of the garbage bin is usually limited, and the garbage bin needs to be emptied after a short period of operation, resulting in insufficient continuous working capacity. Secondly, when a towed sweeper is in operation, its cleaning brushes are usually located on the side. This means that when viewed from above, the brushes cannot completely cover the road surface that the sweeper has passed, thus affecting the sweeper's cleaning effect. Utility Model Content

[0003] The purpose of this utility model is to provide a towed sweeper that solves the problems of limited garbage bin capacity, insufficient continuous working capacity, and inability to completely cover the road surface traversed by the sweeper body during sweeping by setting up a collection bin, a material collection bin, a protective bin, and a fixing plate, thus affecting the sweeping effect.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a towed sweeper, comprising a collection bin, a material collection bin, protective bins, and fixed plates. The top center of the collection bin is fixedly connected to the material collection bin. A cleaning port is provided on the lower periphery of the collection bin. Three protective bins are fixed at the top edge of the collection bin. A spiral blade is movably connected inside the material collection bin. Fixed plates are fixed to the top of the collection bins on both sides of the material collection bin. The lower edge of the cleaning port is chamfered and rounded. The top center of the collection bin is fixedly connected to the material collection bin for collecting garbage during the sweeping process. The material collection bin expands the garbage storage capacity. A cleaning port is provided on the lower side of the collection bin, with chamfered and rounded edges to facilitate garbage entry. Three protective bins are fixed to the top edge of the collection bin for protection. Movable spiral blades are installed inside the material collection bin for lifting garbage. Fixed plates are installed on the top of the collection bins on both sides of the material collection bin for connecting the traveling components.

[0005] Furthermore, a discharge port is fixedly provided at a position symmetrical to the cleaning opening on the periphery of the collection bin. A pin is movably connected inside the discharge port. The collection bin has a discharge port at a position relative to the cleaning opening for discharging garbage. The discharge port is equipped with a removable pin, which is closed during cleaning to prevent leakage and opened during cleaning to discharge garbage.

[0006] Furthermore, a drive motor is fixed at the top center of the collection bin, and a drive shaft is fixed at the output end of the drive motor. The bottom end of the drive shaft is rotatably connected to the bottom of the collection bin, and the drive shaft is fixed through the central axis of the spiral blade. The drive motor is installed at the top center of the collection bin, and its output shaft is connected to the drive shaft. The drive shaft extends downward to the bottom of the collection bin and is rotatably connected to it, while passing through the central axis of the spiral blade. When the motor is running, it drives the spiral blade to rotate through the drive shaft, conveying the waste from the collection bin upward to the collection bin.

[0007] Furthermore, a fixed compartment is fixed at the top edge of the collection bin, and a pull rod is fixed at the center of the periphery of the collection bin. The pull rod is positioned above the protective compartment in the middle when viewed from above. The fixed compartment is provided at the top edge of the collection bin to protect the drive motor. The pull rod is installed in the middle of the side of the collection bin and is positioned above the middle protective compartment when viewed from above. It is used to connect traction equipment or structure to achieve overall movement.

[0008] Furthermore, the protective compartment extends beyond the top of the collection compartment. A servo motor is fixed to the bottom of the protective compartment, and a drive shaft is fixed to the output end of the servo motor. The drive shaft passes through the bottom of the protective compartment, and a rotating disk is fixed to the bottom end of the drive shaft. The drive shaft is located on the outside of the collection compartment, and brush bristles are fixed to the bottom end of the rotating disk. Each rotating disk is movably mounted inside the cleaning port. The protective compartment protrudes from the top of the collection compartment, and a servo motor is installed on its internal bottom side. The motor output shaft is connected to the drive shaft, which passes downward through the bottom of the protective compartment and has a rotating disk installed at its end. Brush bristles are installed at the bottom of the rotating disk. Each rotating disk is located inside the cleaning port. The motor drives the brush bristles to rotate, sweeping the ground debris into the collection compartment.

[0009] Furthermore, the fixing plate extends from the top of the collection chamber, and a connecting block is fixed to the bottom of the fixing plate extending from the collection chamber. Two universal wheels are rotatably connected to the bottom of the connecting block. The fixing plate protrudes from the top of the collection chamber, and the connecting block is installed at its bottom. Two universal wheels are installed below the connecting block to support the entire device to move on the ground and move flexibly with the traction device.

[0010] This utility model has the following beneficial effects: This invention solves the problems of limited garbage bin capacity and insufficient continuous working capacity of towed sweepers by setting up a collection bin and a material collection bin. First, the pull rod on the material collection bin is installed on the pulling device. By pulling the collection bin, the garbage on the ground is swept into the collection bin after the servo motor is started. At the same time as the garbage is being swept, the drive motor is started. The power generated by the drive motor drives the drive shaft and the spiral blades to rotate, which lifts the garbage swept in the collection bin and puts it into the material collection bin, increasing the amount of garbage that the collection bin can hold and making the towed sweeper have a higher continuous working capacity.

[0011] This invention solves the problem that the garbage bins of towed sweepers cannot completely cover the road surface traversed by the sweeper body, thus affecting the cleaning effect, by setting up a collection bin, a protective bin, and a fixing plate. After the collection bin is towed by a motor vehicle, it is supported on the ground through the universal wheels on the connecting block at the bottom of the fixing plate. It moves with the movement of the towing vehicle. At the same time, the servo motor in the protective bin is activated. After the servo motor is activated, it drives the rotating disk and brushes to rotate. During the rotation of the brushes, the garbage on the road surface is swept into the cleaning port on the collection bin and enters the collection bin. By directly covering the rotating disk and brushes on the walking surface of the collection bin, the road surface after the collection bin has moved can be thoroughly cleaned, increasing the thoroughness of the cleaning.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0016] Please see Figure 1-3 This utility model is a towed sweeper, including a collection bin 1, a material collection bin 2, a protective bin 3, and a fixing plate 4. The material collection bin 2 is fixedly connected to the center of the top of the collection bin 1. The collection bin 1 collects the garbage swept during the sweeping process, and the material collection bin 2 increases the garbage capacity. A cleaning port 102 is opened on the lower part of the periphery of the collection bin 1. During the sweeping process, the collection bin 1 collects the garbage into the cleaning port 102. Three protective bins 3 are fixed at the top edge of the collection bin 1. The protective bins 3 protect the servo motor 301 inside. A spiral blade 203 is movably connected inside the material collection bin 2. After the spiral blade 203 rises, it drives the garbage in the material collection bin 2 to rise into the material collection bin 2. The top of the collection bin 1 on both sides of the material collection bin 2 is fixed with a fixing plate 4. The fixing plate 4 is connected to a universal wheel 402. The lower edge of the cleaning port 102 is chamfered and the chamfered edge is rounded to facilitate the garbage entering the material collection bin 2.

[0017] Specifically, a discharge port 101 is fixedly installed at a position symmetrical to the cleaning port 102 on the periphery of the collection chamber 1. A pin 1011 is movably connected inside the discharge port 101. The collection chamber 1 discharges the garbage through the discharge port 101 and seals the discharge port 101 with the pin 1011 to prevent the garbage from leaking during the cleaning process.

[0018] Furthermore, a drive motor 201 is fixed at the top center of the collection bin 2, and a drive shaft 202 is fixed at the output end of the drive motor 201. The bottom end of the drive shaft 202 is rotatably connected to the bottom of the collection bin 1, and the drive shaft 202 is fixed through and fixed at the central axis inside the spiral blade 203. The collection bin 2 drives the drive shaft 202 to rotate through the power generated by the drive motor 201. The rotation of the drive shaft 202 drives the spiral blade 203 to rotate, thereby lifting the garbage in the collection bin 1 into the collection bin 2.

[0019] Furthermore, a fixed chamber 204 is fixed at the top edge of the collection bin 2, and a pull rod 205 is fixed at the center of the periphery of the collection bin 2. The pull rod 205 is positioned above the protective chamber 3 in the middle when viewed from above. The fixed chamber 204 protects the drive motor 201, and the pull rod 205 connects the collection bin 2 and the collection bin 1 to the equipment or structure that pulls the collection bin 1.

[0020] The operation process of this embodiment is as follows: During operation, the pull rod 205 on the collection bin 2 is first installed on the pulling device. By pulling the collection bin 1, the garbage on the ground is swept into the collection bin 1 after the servo motor 301 is started. At the same time as the garbage is being swept, the drive motor 201 is started. The power generated by the drive motor 201 drives the drive shaft 202 and the spiral blade 203 to rotate, which lifts the garbage swept in the collection bin 1 and puts it into the collection bin 2, increasing the amount of garbage that the collection bin 1 can hold. When it is necessary to clean the garbage in the collection bin 1, the drive motor 201 is started to reverse after the pin 1011 in the discharge port 101 is pulled. The garbage collected in the collection bin 2 and the spiral blade 203 is transported back to the collection bin 1 in the reverse direction and then manually removed from the discharge port 101. Specific Implementation

[0021] Please see Figure 1-5 Based on the first specific embodiment, the protective chamber 3 extends beyond the top of the collection chamber 1.

The transmission shaft 302 passes through the bottom of the protective chamber 3, and a rotating disk 303 is fixed at the bottom end of the transmission shaft 302. The transmission shaft 302 is located on the outside of the collection chamber 1. Brushes 304 are fixed at the bottom end of the rotating disk 303. Each rotating disk 303 is movably installed inside the cleaning port 102. The protective chamber 3 fixes and protects the servo motor 301 inside. The servo motor 301 drives the transmission shaft 302 to rotate. When the transmission shaft 302 rotates, it drives the rotating disk 303 and the brushes 304 to rotate. Through the rotation of the brushes 304, after sweeping across the ground, the garbage on the ground is swept into the cleaning port 102 of the collection chamber 1.

[0022] Specifically, the fixing plate 4 extends from the top of the collection chamber 1, and the bottom of the fixing plate 4 extends from the collection chamber 1 and is fixed with a connecting block 401. The bottom of the connecting block 401 is rotatably connected to two casters 402. The fixing plate 4 is connected to the casters 402 through the connecting block 401 extending from the bottom of the top part of the collection chamber 1. The casters 402 support and set the collection chamber 1 on the ground.

[0023] The operation process of this embodiment is as follows: During operation, after the collection bin 1 is towed by a power vehicle, it is supported on the ground by the universal wheel 402 on the connecting block 401 at the bottom of the fixed plate 4. It moves with the movement of the towing vehicle. At the same time, the servo motor 301 in the protection bin 3 starts. After the servo motor 301 starts, it drives the rotating disk 303 and the brush 304 to rotate. During the rotation of the brush 304, the garbage on the road surface is swept into the cleaning port 102 on the collection bin 1 and enters the collection bin 1. By directly covering the rotating disk 303 and the brush 304 on the walking surface of the collection bin 1, the road surface after the collection bin 1 moves can be thoroughly cleaned, increasing the thoroughness of cleaning.
