Abstract
Description
Technical Field
[0001] This utility model relates to the field of sweeper technology, and in particular to a sweeping and conveying mechanism for sweepers. Background Technology
[0002] The sweeping and conveying mechanism of the sweeper is the core system for collecting, transporting, and storing ground debris. The two work together to ensure efficient cleaning and prevent secondary pollution. The sweeping mechanism removes and collects debris such as dust, crumbs, and leaves from the ground, preparing it for subsequent transport. Its core components include a cylindrical brush body covered with high-density nylon bristles or wire brushes. Through high-speed rotation (400-700 rpm), it generates centrifugal force, sweeping the debris from the ground to form a debris flow.
[0003] Traditional sweepers can only clean up garbage on the ground. They have difficulty working on roads with silt or water. So how to solve the above problems has become an urgent problem to be solved.
[0004] An existing patent (publication number: CN212612185U) discloses a sweeping mechanism for a ride-on sweeper, including a sweeping mechanism body, a sweeping mechanism rotating broom head, a sweeping mechanism waste conveyor belt, a sweeping mechanism waste collection bin, and a sweeping mechanism water spraying device. The sweeping mechanism rotating broom head is located at the bottom of the sweeping mechanism body, the sweeping mechanism waste conveyor belt is located on the side of the sweeping mechanism rotating broom head, the sweeping mechanism waste collection bin is located at the top of the sweeping mechanism waste conveyor belt, and the sweeping mechanism water spraying device is located at the top pipe of the sweeping mechanism waste collection bin. This allows the sweeper to quickly clean the ground and purify the surrounding air, while also cleaning silt and larger pebbles from flat surfaces.
[0005] To address the aforementioned issues, while existing patents offer solutions that enable sweepers to quickly clean the ground and purify the surrounding air, and can also remove silt and larger pebbles from flat surfaces, the wear and tear on the sweeper's roller brush leads to a reduction in its diameter. While the amount of contact between the roller brush and the ground can be compensated for by adjusting the distance between the center of the roller brush and the ground, it cannot compensate for the problem of garbage leakage during sweeping operations caused by the increased distance between the reduced roller brush diameter and the rear bumper, garbage bin, and garbage conveying mechanism. Summary of the Invention
[0006] The purpose of this utility model is to provide a sweeping and conveying mechanism for a sweeper. A sweeping motor drives a first sweeping roller to rotate, sweeping the ground. The motor also drives a drive rod to rotate, which in turn drives two adjusting components to move synchronously. These adjusting components, through a hinged rod, synchronously rotate the drive rod on the first sweeping roller, causing the first sweeping roller to contact the ground. After the first sweeping roller is adjusted, the outer diameter of the second sweeping roller always maintains a stable distance from the outer diameter of the first sweeping roller. The second sweeping roller is positioned above and behind the first sweeping roller, vertically penetrating the inner side of the feed inlet of the conveyor box. This prevents the increased distance between the second and conveyor boxes due to the reduced roller diameter, thus avoiding garbage leakage during sweeping operations. This addresses the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a sweeping and conveying mechanism for a sweeper, comprising a sweeping box, a conveying box connected to the right side of the sweeping box, a cleaning mechanism for cleaning the ground inside the sweeping box, and a filtering mechanism for filtering dust on the right side of the conveying box.
[0008] The cleaning mechanism includes a first cleaning roller brush, which is installed inside the cleaning box. A second cleaning roller brush is provided above the first cleaning roller brush. Fixed bearings are fitted at both ends of the second cleaning roller brush and the first cleaning roller brush. An adjusting component is fixed to the outer wall of the fixed bearing. A hinge rod is hinged to one side of the adjusting component.
[0009] As a further embodiment of this utility model: a drive rod is fixed to the end of the adjusting member, and one end of the drive rod is connected to a motor that is fixed to the outer wall of the cleaning box by bolts.
[0010] As a further embodiment of this utility model: the input end of the first cleaning roller brush is connected to a cleaning motor fixed to the outer wall of the cleaning box, and a third cleaning roller brush is installed inside the cleaning box and on the left side near the first cleaning roller brush.
[0011] As a further improvement of this utility model: a conveyor belt is installed inside the conveyor box, and several scraper plates are fixed at equal intervals on the side wall of the conveyor belt.
[0012] As a further embodiment of this utility model: the filtering mechanism includes a filter element, the filter element is connected to the right side of the conveying box, the upper surface of the filter element is connected to an air outlet, and the upper surface of the air outlet is provided with an exhaust hole.
[0013] As a further improvement of this utility model: a guide plate is integrally fixed to the inner side of the filter element, and a filter screen is fixed horizontally inside the air outlet element.
[0014] As a further improvement of this utility model: an ultrasonic generator fixed inside the filter element is connected to the upper surface of the filter screen, an exhaust fan is installed on the inner wall of the air outlet element, and a trash can is connected to the lower end of the filter element.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. Through the cleaning mechanism, the sweeping motor drives the first sweeping roller to rotate and sweep the ground. The motor drives the drive rod to rotate, which in turn drives the two adjusting parts to move synchronously. When the two adjusting parts move, they drive the drive rod on the first sweeping roller to rotate synchronously through the hinge rod, thereby driving the first sweeping roller to contact the ground. After the first sweeping roller is adjusted, the outer diameter surface of the second sweeping roller always maintains a stable distance from the outer diameter surface of the first sweeping roller. The second sweeping roller is arranged behind and above the first sweeping roller, and penetrates into the inner side of the feed inlet of the conveyor box in the vertical direction. It will not cause the distance between the roller and the conveyor box to increase due to the reduction of the roller diameter, which would lead to the leakage of garbage during the sweeping operation.
[0017] 2. Through the set filtration mechanism, the garbage is lifted to the top of the garbage bin by the scraper on the conveyor belt, and falls into the garbage bin after passing through the guide plate on the filter. The garbage is directly swept into the bin. When the bin is full, it is replaced with an empty bin to continue the operation, avoiding secondary pollution and secondary handling of garbage. The exhaust component has exhaust holes. When the garbage falls into the garbage bin, it will generate dust. The exhaust fan will draw out the air, and the air will filter the dust as it passes through the filter screen, thereby reducing dust. Attached Figure Description

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a technical solution:
[0027] Please see Figures 1 to 4 A sweeping and conveying mechanism for a sweeper includes a sweeping box 1, a conveying box 2 connected to the right side of the sweeping box 1, a cleaning mechanism for cleaning the ground inside the sweeping box 1, and a filtering mechanism for filtering dust on the right side of the conveying box 2.
[0028] The cleaning mechanism includes a first cleaning roller brush 3, which is installed inside the cleaning box 1. A second cleaning roller brush 31 is provided above the first cleaning roller brush 3. Fixed bearings 32 are fitted at both ends of the second cleaning roller brush 31 and the first cleaning roller brush 3. An adjusting member 33 is fixed to the outer wall of the fixed bearing 32. A hinge rod 34 is hinged to one side of the adjusting member 33. A drive rod 35 is fixed to the end of the adjusting member 33. A motor 36 is connected to one end of the drive rod 35 and fixed to the outer wall of the cleaning box 1 by bolts. A cleaning motor 37 fixed to the outer wall of the cleaning box 1 is connected to the input end of the first cleaning roller brush 3. A third cleaning roller brush 38 is installed inside the cleaning box 1 and on the left side near the first cleaning roller brush 3. A conveyor belt 4 is installed inside the conveyor box 2. Several scraper blades 5 are fixed at equal intervals on the side wall of the conveyor belt 4.
[0029] By adopting the above technical solution and assembling the mechanism in a suitable position, the cleaning motor 37 on the cleaning box 1 drives the first cleaning roller brush 3 to rotate. The fixed bearing 32 ensures the smooth rotation of the roller brush, thereby cleaning the ground. The third cleaning roller brush 38 replaces the baffle opening and closing mechanism. The rotation of the third cleaning roller brush 38 continuously sweeps the garbage into the first cleaning roller brush 3. The first cleaning roller brush 3 sweeps the garbage into the cleaning box 1 and then drops it into the conveyor box 2. The conveyor belt 4 inside the conveyor box 2 is driven by an external motor, which in turn drives the scraper 5 to move, conveying the garbage upwards. The second cleaning roller brush 31, driven by an external motor, can sweep away the garbage adhering to the surface of the first cleaning roller brush 3, thereby reducing the possibility of garbage being carried back to the ground. When the first cleaning roller brush 3 of the mechanism wears out, the motor 36 drives the drive rod 35 to rotate, which in turn drives the two adjusting parts 33 to move synchronously. At this time, the second cleaning roller brush 31 at the end of the adjusting part 33 is driven to move downward. Simultaneously, when the two adjusting parts 33 move, the hinge rod 34 drives the drive rod 35 on the first cleaning roller brush 3 to rotate synchronously, thereby driving the first cleaning roller brush 3 to contact the ground, thus ensuring the cleaning effect. After the first cleaning roller brush 3 is adjusted, the outer diameter surface of the second cleaning roller brush 31 always maintains a stable distance from the outer diameter surface of the first cleaning roller brush 3. The second cleaning roller brush 31 is arranged above and behind the first cleaning roller brush 3, and penetrates into the inner side of the feed inlet of the conveyor box 2 in the vertical direction. It will not increase the distance from the conveyor box 2 after the roller brush diameter is reduced to compensate, which would lead to the leakage of garbage during the cleaning operation.
[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the filtration mechanism includes a filter element 6, which is connected to the right side of the conveying box 2. An air outlet 61 is connected to the upper surface of the filter element 6, and an exhaust hole 62 is opened on the upper surface of the air outlet 61. A guide plate 63 is integrally fixed to the inner side of the filter element 6. A filter screen 64 is fixed horizontally inside the air outlet 61. An ultrasonic generator 65 fixed inside the filter element 6 is connected to the upper surface of the filter screen 64. An exhaust fan 66 is installed on the inner wall of the air outlet 61. A garbage bin 7 is connected to the lower end of the filter element 6.
[0031] By adopting the above technical solution, the garbage is lifted by the scraper 5 on the conveyor belt 4 to the top of the garbage bin 7, passes through the guide plate 63 on the filter element 6, and falls into the garbage bin 7. The garbage is directly swept into the bin. When the bin is full, it is replaced with an empty bin to continue the operation, avoiding secondary pollution and secondary handling of garbage. The exhaust element 61 is provided with an exhaust hole 62. When the garbage falls into the garbage bin 7, dust will be generated. The exhaust fan 66 is set to extract the air. When the air passes through the filter screen 64, the dust is filtered, thereby reducing dust. After use, the ultrasonic generator 65 generates vibration to shake off the dust blocked on the filter screen 64.
[0032] Working principle: The sweeping motor 37 drives the first sweeping roller brush 3 to rotate. The third sweeping roller brush 38 replaces the baffle opening and closing mechanism. The rotation of the third sweeping roller brush 38 continuously sweeps the garbage into the first sweeping roller brush 3. The first sweeping roller brush 3 sweeps the garbage into the sweeping box 1, and then it falls into the conveyor box 2. The conveyor belt 4 set in the conveyor box 2 is driven by an external motor, which in turn drives the scraper 5 to move, which can transport the garbage inside upward. The second sweeping roller brush 31 sweeps away the garbage adhering to the surface of the first sweeping roller brush 3, reducing the possibility of garbage being carried back to the ground. The motor 36 drives the drive rod 35 to rotate, so that the drive rod 35 synchronously drives the two adjusting parts 33 to move. At this time, the second sweeping roller brush 31 at the end of the adjusting part 33 is driven to move downward. At the same time, when the two adjusting parts 33 move, through the set hinge rod 34, it will... The drive rod 35 on the first cleaning roller brush 3 rotates synchronously, thereby driving the first cleaning roller brush 3 to contact the ground, thus ensuring the cleaning effect. After the first cleaning roller brush 3 is adjusted, the outer diameter surface of the second cleaning roller brush 31 always maintains a stable distance from the outer diameter surface of the first cleaning roller brush 3. The second cleaning roller brush 31 is arranged above and behind the first cleaning roller brush 3, and penetrates into the inner side of the feed inlet of the conveyor box 2 in the vertical direction. It will not cause the distance between the roller brush and the conveyor box 2 to increase after the roller brush diameter is reduced to compensate, resulting in the leakage of garbage during the cleaning operation. The garbage is lifted by the scraper 5 on the conveyor belt 4 to the top of the garbage bin 7, passes through the guide plate 63 on the filter element 6, and falls into the garbage bin 7. The air outlet 61 has an exhaust hole 62. When the garbage falls into the garbage bin 7, it will generate dust. The exhaust fan 66 draws out the air, and the air is filtered by the filter screen 64.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
