Description

Technical Field

[0001] This utility model belongs to the technical field of road sweeping equipment, specifically relating to a dual-fan negative pressure mechanism and a high-speed road sweeper. Background Technology

[0002] With the rapid development of mechanized road cleaning in my country, large-scale urban road cleaning operations are now mainly carried out by dedicated road sweepers. When operating, the road sweeper sweeps road debris to the area in front of the suction nozzle, and as the suction nozzle passes by, the debris is sucked into the garbage bin by the suction provided by the blower.

[0003] The connection between the blower and engine of existing high-speed sweeper trucks is mostly belt drive or chain drive, which often requires tensioning pulleys for tensioning. However, existing tensioning pulleys are often fixed to the sweeper truck or need to be disassembled to adjust their position, making it impossible to adjust the required tension at any time. Furthermore, due to the characteristics of belt drive or chain drive, the position of the tensioning pulley needs to be adjusted frequently during maintenance. Adjusting the existing blower negative pressure mechanism is time-consuming and labor-intensive. Utility Model Content

Connecting plates are connected to both sides of the housing, and connecting disks are connected to the ends of the two connecting plates. A drive disk is rotatably connected to the connecting disks. A lifting plate is connected to the inner side of the drive disk. Several lifting teeth that cooperate with the lifting plate are opened on the side of the vertical slider. By rotating the lifting plate, the vertical slider can be lifted upward, thereby driving the tensioning wheel to lift. A rotating assembly is connected to the outer side of the drive disk, and the rotating assembly can drive the drive disk to rotate.

[0008] Preferably, a gear is coaxially fixedly connected to the outer side of the drive disc, and a drive handle is rotatably connected to the outer side of the gear; an L-shaped plate is connected to the drive handle, one end of the L-shaped plate is rotatably connected to the drive handle, and the other end of the L-shaped plate is connected to a reverse tooth, which can hook the gear tooth so that the gear rotates when the drive handle rotates.

[0009] Preferably, the lifting plate is a planar spiral structure with a gradually increasing radius.

[0010] Preferably, the outer side of the tensioning wheel is provided with an arc-shaped baffle for dust prevention. The arc-shaped baffle is fixed to the top of the vertical slider, and both brackets are connected to the inner side of the arc-shaped baffle.

[0014] 1. This utility model, by setting a tensioning component, allows the tensioning wheel to be raised or lowered by rotating the drive handle, without the need to disassemble and install the tensioning wheel to adjust its position. At the same time, by moving the L-shaped plate to rotate it to the opposite side, the position can be locked by the reverse teeth, making adjustment convenient and quick.

[0025] Example 1:

[0026] Please see Figures 1-4 This embodiment proposes a dual-fan negative pressure mechanism, which can be used not only in high-speed road sweepers but also in industrial production such as workshop vacuuming. It includes a base 1, with two sets of uprights 2 connected to the base 1. The two uprights 2 are respectively equipped with a first fan 3 and a second fan 4, and the first fan 3 and the second fan 4 are connected by a cross shaft coupling 5. A drive assembly 6 is provided on one side of the uprights 2, and the drive assembly 6 is connected to the input end of the first fan 3 through a transmission assembly 7. A tensioning assembly 8 is provided at the bottom of the transmission assembly 7.

[0027] The transmission method can be either sprocket and chain drive or belt drive. This embodiment uses belt drive. The transmission component 7 in this embodiment includes a first pulley 71 and a second pulley 72, which are connected by a transmission belt 73. The first pulley 71 is connected to the drive component 6, and the second pulley 72 is connected to the input end of the first fan 3.

[0028] In this embodiment, the drive assembly 6 includes an engine 61.

The engine 61 outputs power and transmits it to the first fan 3 through the transmission assembly 7. The first fan 3 then transmits the power to the second fan 4 through a cross shaft coupling 5, thereby achieving synchronous drive of the two fans.

[0029] Example 2:

[0030] Continue reading Figures 1-4 This embodiment proposes a tensioning assembly 8, including a fixed plate 82, a housing 83 on the fixed plate 82, a vertical slider 84 slidably connected inside the housing 83, two supports 811 connected to the top of the vertical slider 84, and a tensioning wheel 81 rotatably connected between the two supports 811; connecting plates 85 are connected to both sides of the housing 83, and connecting disks 86 are connected to the ends of the two connecting plates 85; a drive disk 88 is rotatably connected to the connecting disk 86; a lifting plate 87 is connected to the inner side of the drive disk 88; the lifting plate 87 is a planar spiral structure with a gradually increasing radius, and a number of lifting teeth 810 that cooperate with the lifting plate 87 are opened on the side of the vertical slider 84. By rotating the lifting plate 87 in the forward direction, the vertical slider 84 can be lifted upward, driving the tensioning wheel 81 to lift; a rotating assembly is connected to the outer side of the drive disk 88, and the rotating assembly can drive the drive disk 88 to rotate.

[0031] To facilitate the rotation of the drive disc 88, a gear 89 is coaxially fixedly connected to the outside of the drive disc 88. The drive handle 813 is rotatably connected to the outside of the gear 89. The drive handle 813 passes through the body 9 of the high-speed sweeper and is located outside the body 9. An L-shaped plate 814 is connected to the drive handle 813. One end of the L-shaped plate 814 is rotatably connected to the drive handle 813, and the other end of the L-shaped plate 814 is connected to a reverse tooth 815. The reverse tooth 815 can hook the tooth of the gear 89, so that the drive handle 813 rotates and drives the gear 89 to rotate.

[0032] Working principle:

[0033] Forward rotation (in the attached) Figure 3(The middle part rotates clockwise) Drive handle 813, L-shaped plate 814 rotates to the left position, reverse gear 815 engages with the teeth of gear 89, thereby causing drive handle 813 to drive drive disk 88 to rotate. Drive disk 88 rotates in the forward direction, the outer edge of lifting plate 87 continuously expands, causing lifting gear 810 to continuously move upward, driving vertical slider 84 to move upward, and tension wheel 81 to move upward at the same time. If descent is required, the operation is reversed, L-shaped plate 814 is rotated to the right position, and counterclockwise rotation is descent; once the position is determined, it is only necessary to adjust L-shaped plate 814 to the left position to achieve limit fixation, and it cannot descend under the clamping of reverse gear 815.

[0034] In addition, in order to reduce frictional damage to the belt surface, the outer surface of the tensioner 81 of the belt drive is usually covered with a relatively soft rubber layer. The rubber layer is prone to dust accumulation. Therefore, an arc-shaped baffle 812 for dust prevention is provided on the outside of the tensioner 81. The arc-shaped baffle 812 is fixed to the top of the vertical slider 84, and both brackets 811 are connected to the inner side of the arc-shaped baffle 812.

[0036] Please see Figures 1-5 Based on the above embodiments, this embodiment proposes a high-speed road sweeper, including a vehicle body 9.

The vehicle body 9 is equipped with two sets of storage chambers 10, which are respectively connected to the first fan 3 and the second fan 4, and can suck out the gas in the storage chamber 10 to form a negative pressure in the storage chamber 10. The storage chamber 10 is equipped with a dust suction pipe 11, one end of which is located in the storage chamber 10 and the other end is located at the bottom of the vehicle body 9, which can suck the material at the bottom of the vehicle body 9 into the storage chamber 10.
