Technical Field
[0001] This utility model belongs to the field of sanitation equipment technology, specifically relating to a hand-held sanitation snowplow. Background Technology
[0002] Maintaining environmental sanitation is crucial in public areas such as city streets, communities, and parks. Ground cleaning has always been a key aspect of sanitation work. Traditional manual sweeping requires sanitation workers to repeatedly bend over for extended periods, resulting in extremely high labor intensity. Existing small cleaning tools are relatively limited in function and cannot meet diverse cleaning needs.
[0003] In urban environmental sanitation maintenance, especially snow removal, is a fundamental and crucial task, particularly in northern cities prone to snowfall. While heavy snow brings beautiful scenery, it also brings severe natural disasters. Prolonged and heavy snowfall poses a significant challenge to urban transportation systems, one aspect being snow-covered roads that become congested. Snow-covered roads severely impede the safety of vehicles and pedestrians, making road snow removal equipment particularly important. Traditional methods of snow removal, such as manual clearing using shovels and carts, are not only inefficient and time-consuming, but also ineffective at clearing large areas of snow, water, stains, and debris. Furthermore, while large cleaning equipment offers advantages in efficiency, it often lacks flexibility and struggles to perform precise operations in narrow streets, sidewalks, and park paths. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a walk-behind sanitation snowplow. The walk-behind sanitation snowplow can adjust the angle and position of the push plate, so that the push plate can easily push and transport materials with different cleaning needs in different usage scenarios, especially for snow cleaning in the north. The rubber scraper can avoid the push plate directly contacting the ground, thus reducing the occurrence of jamming and impact due to uneven ground. At the same time, the rubber scraper is relatively soft and can also be used on brick and stone paved ground, reducing the possibility of bricks and stones being lifted due to pushing.
[0005] A walk-behind snowplow for sanitation includes a protective plate. A positioning seat is fixedly connected to one side of the outer surface of the protective plate. An adjusting rod is slidably connected to the inner wall of the positioning seat. A main universal wheel is fixedly installed at the bottom end of the adjusting rod. A positioning cylinder is fixedly connected to the outer wall of the protective plate below the positioning seat. A support rod is inserted into the inner wall of the positioning cylinder. Support frames are sleeved on both sides of the outer surface of the support rod. A push plate is fixedly installed at the end of the support frame. A rubber scraper is detachably connected to the lower part of the outer surface of the push plate by bolts. A secondary universal wheel is fixedly installed at the bottom of the support frame. A limit seat is fixedly connected to the outer wall of the protective plate at the top of the positioning cylinder. A fastening screw is inserted into the outer surface of the limit seat. Push rods are rotatably connected to the outer surface of the fastening screw on both sides of the limit seat.
[0006] Preferably, a power mechanism is fixedly installed on the top of the protective plate, and a differential is fixedly installed on the bottom of the protective plate. Both sides of the differential are connected to drive wheels via drive shafts.
[0007] Preferably, a fixing rod is threaded through the outer surface of the positioning seat, and a fixing hole adapted to the fixing rod is opened on the outer surface of the adjusting rod. One end of the fixing rod that passes through the positioning seat is inserted into the inner wall of the fixing hole.
[0008] Preferably, a pressure rod is threaded through the outer surface of the positioning cylinder, and one end of the pressure rod that penetrates the positioning cylinder abuts against the outer wall of the support rod.
[0009] Preferably, the outer surface of the support rod is threaded with limiting rods on both sides of the support frame, and the inner wall of the support frame is fixedly connected with a protective pad on the outer surface of the support rod.
[0010] Preferably, a limiting ring is fixedly connected to the side of the outer surface of the push rod near the limiting seat, and a fixing nut is threadedly connected to one end of the fastening screw that protrudes from the push rod.
[0011] Preferably, a controller for controlling the power mechanism is fixedly installed on the outer surface of one of the push rods, and a handbrake lever is rotatably connected between the two push rods.
[0012] Preferably, a pull cable is fixedly connected to the end of the handbrake lever, an adjusting cylinder is fixedly connected to the end of the pull cable, and the other end of the adjusting cylinder, a steel wire rope, is fixedly connected to the outer surface of the push plate.
[0013] The beneficial effects of the above technical solution are as follows:
[0014] (1) The hand-held sanitation snowplow, through the combination of positioning seat and adjustment rod, can adjust the tilt angle of the push plate by adjusting the position of the adjustment rod, so that the staff can choose different pushing angles according to the different materials to be pushed, thereby improving the applicability of the device. In addition, the rubber scraper below can also avoid the situation of jamming and impact caused by uneven ground by its own material. The rubber scraper can also push snow, water and mud better, making it easier for staff to operate.
[0015] (2) The hand-held sanitation snowplow, through the combination of the limit seat and the push rod, can adjust the push rod to the optimal angle according to the different heights of the users, making it easier for the staff to exert force and operate. At the same time, with the help of the main universal wheel and the auxiliary universal wheel, it is easier for the staff to operate and turn, further improving the practicality of the device.

[0021] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 4 The embodiments are described in detail below.
[0022] This embodiment provides a walk-behind snowplow for sanitation work, as shown in the attached drawing. It includes a protective plate 1, a power mechanism 2 fixedly mounted on the top of the protective plate 1, and a differential 3 fixedly mounted below the protective plate 1. Both sides of the differential 3 are connected to drive wheels 4 via drive shafts. The protective plate 1 serves as the main structure of the entire device, acting as a basic frame to support and connect other components, providing a stable mounting base for them, integrating all functional components into a unified whole. The protective plate 1 also shields the workers from the mud kicked up by the drive wheels 4. The power mechanism 2 provides the power source for the device, driving the entire snowplow and enabling it to operate autonomously. The differential 3 distributes power to the drive wheels 4 via the drive shaft, while adjusting the speed difference between the two drive wheels 4. This allows the bulldozer to turn with different speeds on the inner and outer drive wheels 4, enabling flexible turning and improving the mobility and maneuverability of the device in different environments. Especially in narrow streets or areas requiring turning, it ensures smooth turning. The drive wheels 4 are in contact with the ground and, driven by the power mechanism 2 and the differential 3, move the device, propelling the entire bulldozer forward or backward. This is the key component for realizing the overall movement of the device, allowing it to quickly move between different areas and improve work efficiency.
[0023] A positioning seat 5 is fixedly connected to one side of the outer surface of the protective plate 1. An adjusting rod 6 is slidably connected to the inner wall of the positioning seat 5. A main universal wheel 7 is fixedly installed at the bottom end of the adjusting rod 6. A fixing rod 8 is threaded through the outer surface of the positioning seat 5. A fixing hole 9 that matches the fixing rod 8 is opened on the outer surface of the adjusting rod 6. One end of the fixing rod 8 is inserted into the inner wall of the fixing hole 9. Through the cooperation between the positioning seat 5 and the adjusting rod 6, the inner wall of the positioning seat 5 is slidably connected to the adjusting rod 6, providing support and guidance for the sliding of the adjusting rod 6. By adjusting the position of the adjusting rod 6, the tilt angle of the push plate 15 can be adjusted, thereby adapting to the pushing needs of different materials, improving the applicability of the device, and enabling the device to adjust the angle of the push plate 15 according to specific conditions, flexibly handling different types of cleaning tasks. The fixing hole 9 is used for fixing. Rod 8 can fix the adjusting rod 6 in the required position, while the main caster wheel 7 helps to support the entire device and move it flexibly. Especially when adjusting the angle, the adjusting rod 6 can be fixed in different positions to make the push plate 15 at the appropriate angle. The main caster wheel 7 is installed at the bottom of the adjusting rod 6 and can rotate in multiple directions, which facilitates the flexible movement of the device in different directions. Especially when it is necessary to adjust the angle or turn, it provides additional support and flexibility, making the device easier to operate and turn, and improving the overall mobility. The fixing rod 8 is threaded through the outer surface of the positioning seat 5, and one end can be inserted into the fixing hole 9 of the adjusting rod 6. When the adjusting rod 6 is adjusted to the appropriate position, it is fixed on the positioning seat 5 to prevent the adjusting rod 6 from sliding during operation, ensuring the stability of the angle of the push plate 15 and ensuring the smooth progress of the cleaning work.
[0024] A positioning cylinder 10 is fixedly connected to the outer wall of the protective plate 1 below the positioning seat 5. A support rod 11 is inserted into the inner wall of the positioning cylinder 10. A pressure rod 12 is threaded through the outer surface of the positioning cylinder 10. One end of the pressure rod 12, which is inserted into the positioning cylinder 10, abuts against the outer wall of the support rod 11. Support frames 13 are sleeved on both sides of the outer surface of the support rod 11. Limiting rods 14 are threaded through both sides of the outer surface of the support rod 11 and the inner wall of the support frame 13 is fixedly connected to the outer surface of the support rod 11. A push plate 15 is fixedly installed at the end of the support frame 13. A rubber scraper 16 is detachably connected to the lower part of the outer surface of the push plate 15 by bolts. A secondary universal wheel 17 is fixedly installed at the bottom of the support frame 13. The support rod 11 is inserted into the inner wall of the positioning cylinder 10. The support rod 11 provides positioning and support, ensuring its relatively stable position and providing a stable connection for the support structure of the push plate 15. This ensures the normal operation of the push plate 15 and facilitates subsequent position adjustment and fixation of the support rod 11. Support frames 13 are sleeved on both sides of the outer surface of the support rod 11 and fixed by limiting rods 14, etc., providing the main support force for the push plate 15 and its auxiliary components, ensuring the stability of the push plate 15 during operation, and providing a basis for height and position adjustment of the push plate 15. The pressure rod 12 is threaded through the outer surface of the positioning cylinder 10, with one end abutting against the outer wall of the support rod 11, firmly fixing the support rod 11 inside the positioning cylinder 10 and preventing loosening or shaking during operation. To ensure the stability of the push plate 15 and its auxiliary components, a support frame 13 is sleeved on the outer surface of the support rod 11, with the push plate 15 fixedly installed at its end. A secondary universal wheel 17 is installed at the bottom, connecting the support rod 11 and the push plate 15, transmitting the supporting force of the support rod 11 to the push plate 15. Simultaneously, the secondary universal wheel 17 assists in the movement and steering of the device, making the device more flexible during operation, especially maintaining overall balance and stability when the push plate 15 is working. A limit rod 14 is threaded through the outer surface of the support rod 11 and located on both sides of the support frame 13, further fixing the support frame 13 and preventing it from sliding or shaking on the support rod 11, ensuring the stability and operational reliability of the push plate 15. The push plate 15 is installed at the end of the support frame 13, below its outer surface. The rubber scraper 16, detachably connected by bolts, is used to push materials. During the operation of the scraper, it pushes and collects snow, garbage, stains, water, and mud on the ground, achieving cleaning. It is the main component for cleaning operations. The rubber scraper 16 contacts the ground, preventing the pusher plate 15 from directly contacting the ground, reducing the impact and jamming caused by uneven ground. Due to its soft material, it reduces the risk of bricks and stones lifting when used on masonry surfaces. It also has a better pushing effect on snow, water, and mud, achieving better cleaning results and expanding the device's applicability. Furthermore, the bolted installation allows for replacement after significant wear and tear, enhancing the device's practicality.The auxiliary caster 17, in conjunction with the main caster 7 and drive wheels 4, enhances the device's flexibility, especially in confined spaces or when delicate operations are required, improving the equipment's maneuverability and operability.
[0025] The outer wall of the protective plate 1 is fixedly connected to the top of the positioning cylinder 10 with a limiting seat 18. A fastening screw 19 is inserted into the outer surface of the limiting seat 18. Push rods 20 are rotatably connected to both sides of the outer surface of the fastening screw 19, which are located on both sides of the limiting seat 18. A limiting ring 21 is fixedly connected to the outer surface of the push rod 20 near the limiting seat 18. A fixing nut 22 is threaded onto one end of the fastening screw 19 that protrudes from the push rod 20. The fastening screw 19 is inserted into the outer surface of the limiting seat 18, providing a position for the push rod 20. The position and angle of the push rod 20 can be adjusted to accommodate the operating habits of operators of different heights, making it easier for operators to control the device and improving work comfort and efficiency. A rotatable push rod 20 is connected to a threaded nut 22 at one end, which can fix the push rod 20 in the required position and angle, ensuring the stability of the push rod 20 and preventing it from loosening or shaking during operation, thus ensuring the reliability of operation. The operator controls the forward, backward, and directional movement of the device through the push rod 20, making it convenient for the operator to apply force to push the device. This allows the operator to easily control the movement and direction of the shovel and pusher, achieving flexible operation of the device. A limit ring 21 is fixedly connected to the outer surface of the push rod 20 near the limit seat 18, and cooperates with the fastening screw 19 and the fixing nut 22 to limit the position of the push rod 20, prevent the push rod 20 from sliding, and ensure the stability and safety of operation.
[0026] A controller 23 for controlling the power mechanism 2 is fixedly installed on the outer surface of one of the push rods 20. A handbrake lever 24 is rotatably connected between the two push rods 20. A pull cable 25 is fixedly connected to the end of the handbrake lever 24, and an adjusting cylinder 26 is fixedly connected to the end of the pull cable 25. The other end of the adjusting cylinder 26, a steel wire rope, is fixedly connected to the outer surface of the push plate 15. The controller 23 is installed on the outer surface of one of the push rods 20 to control the power mechanism 2. The operator can easily operate the power mechanism 2 through the controller 23 to control the speed and start / stop of the shovel and pusher, making operation more convenient. The handbrake lever 24 is rotatably connected between the two push rods 20, and the pull cable 25 is fixedly connected to the end. Pulling the handbrake lever 24 rotates the pull cable 25, which adjusts the tightness of the pull cable 25. The height of the push plate 15 can be controlled by adjusting the tension of the pull cable 25. This makes it easier for operators to adjust according to different usage scenarios, improving operational convenience and overall ease of operation. Controllability: One end of the pull cable 25 is fixedly connected to the end of the handbrake lever 24. Adjusting cylinder 26 has adjusting screws connected to both ends via positive and negative threads. The upper adjusting screw is connected to the pull cable 25, and the lower adjusting screw is connected to the wire rope. Rotating the adjusting cylinder 26 allows the adjusting screws at both ends to move closer or further apart, thereby adjusting the tension between the pull cable 25 and the wire rope. This makes it easier for operators to apply force using the handbrake lever 24, and also allows for periodic adjustment of the tension of the pull cable 25. This extends the service life of the pull cable 25, thereby improving the practicality of the device. The structure of the pull cable 25 is the same as that of the brake cable. The outer surface of the pull cable 25 is wrapped with a rubber sleeve, and the pull cable 25 can slide in the rubber sleeve. One end of the rubber sleeve is fixedly connected between the two push rods 20, and the other end of the rubber sleeve is fixedly connected to the protective plate 1 located at the front end of the power mechanism 2. Thus, the pull cable 25 can pull the adjusting cylinder 26 under the pull of the handbrake lever 24, and then pull and adjust the push plate 15 with the help of the steel wire rope.
[0027] When the operator pulls the handbrake lever 24, the state of the push plate 15 can be adjusted to a certain extent through the pull cable 25, so that the push plate 15 can be flexibly adjusted according to actual needs during operation, thereby improving the performance of the device. The structure of the handbrake lever 24 is mainly composed of a hand grip and a handbrake pawl, which is the same as the structure of the mechanical handbrake lever in automobiles in the prior art, so it will not be described in detail here. The handbrake lever 24 can be positioned at any position when pulled up, and can be unlocked by the button at the end of the handbrake. Therefore, when the operator presses the button at the end of the handbrake lever 24, the handbrake lever 24 can be lifted, and the position and angle of the lifting can be adjusted, thereby adjusting the degree of lifting of the push plate 15.
[0028] This invention particularly emphasizes that in snow removal operations, especially when snow is being cleared while it is still falling and not yet frozen, this invention facilitates clearing and can be used directly. For frozen snow, it is usually necessary to melt or break it before using this invention for clearing.
[0029] In summary, the operating steps for this walk-behind snowplow are as follows:
[0030] 1. Depending on the material to be pushed, adjust the angle of the push plate 15, loosen the fixing rod 8 on the positioning seat 5, slide the adjusting rod 6 so that the adjusting rod 6 slides up and down on the inner wall of the positioning seat 5, thereby changing the tilt angle of the push plate 15. After finding a suitable angle, insert the fixing rod 8 into the positioning seat 5 and insert it into the corresponding fixing hole 9 on the adjusting rod 6, tighten the fixing rod 8, and fix the adjusting rod 6 in this position to ensure that the angle of the push plate 15 will not change after it is adjusted.
[0031] 2. Adjusting the position of push rod 20: Adjust the position and angle of push rod 20 according to the operator's height and operating habits. Loosen the fixing nut 22 on the fastening screw 19, rotate push rod 20, and adjust push rod 20 to the most suitable position for the operator to exert force and control. After adjustment, tighten the fixing nut 22 so that the fastening screw 19 firmly fixes push rod 20 on limit seat 18, ensuring that push rod 20 will not loosen or shift during operation.
[0032] 3. Start the power mechanism 2 by operating the controller 23. Start the power mechanism 2 through the controller 23 to make the power mechanism 2 start working, provide power to the shovel and pusher, and provide stable power output to the differential 3 and drive wheel 4. Hold the push rod 20 with both hands to make the drive wheel 4 rotate, and push the entire shovel and pusher forward or backward.
[0033] 4. By utilizing the characteristics of differential 3, and the multi-directional rotation characteristics of main caster 7 and auxiliary caster 17, the equipment can be flexibly turned and moved in narrow streets, sidewalks and other areas, enabling the equipment to smoothly shuttle through different terrain environments.
[0034] 5. When pushing the pusher forward, the push plate 15 and the rubber scraper 16 below it will contact the ground, pushing the snow, garbage, stains, water, mud and other materials on the ground forward. During the pushing process, the state of the push plate 15 can be adjusted by the handbrake lever 24 and the pull cable 25 according to the actual situation to achieve a better cleaning effect.
