Description

Technical Field

[0001] The utility model relates to the technical field of electric sewage suction vehicles, in particular to an adjustable sewage suction arm for the electric sewage suction vehicle. Background Art

[0002] Electric sewage suction trucks are mainly used for the suction, transportation and unloading of sewage, sludge, sand and gravel, and large blocks from various underground sewage pipes, rainwater wells and manholes in cities. They can also be used for the suction and transportation of sewage, industrial waste oil and wastewater from large factories and mines, as well as the dredging and unblocking of small rivers. As a cleaning vehicle for urban municipalities, the combined sewage suction truck is frequently used in the daily maintenance of cities.

[0003] Chinese patent CN213868248 U discloses an adjustable sewage suction arm for a sewage suction vehicle, comprising a base and an outer gear ring, a connecting column fixedly installed on the top of the base, a rotating table movably installed on the top of the connecting column, two fixed plates fixedly installed on the top of the rotating table, a box body movably installed between the two fixed plates through bearings, an opening is provided on the right side of the box body, a partition is fixedly installed inside the box body, a screw rod is movably installed between the partition plate and the right side of the inner wall of the box body through a bearing, a first motor is fixedly installed on the right side of the box body, an output end of the first motor is fixedly connected to one end of the screw rod, a second slider is threadedly sleeved on the screw rod, a second fixing ring is fixedly installed on one side of the second slider, and a sewage suction connecting pipe is fixedly installed inside the second fixing ring. The specification discloses in paragraph

[0025] that “when the dirt suction arm needs to be rotated, first tighten the limit nut 24, start the second motor 20, the second motor 20 drives the driving gear 21 to rotate, the driving gear 21 drives the outer gear ring 3 to rotate, the outer gear ring 3 drives the rotating table 17 to rotate, the rotating table 17 drives the box 19 to rotate through the two fixing plates 4, and rotates to a suitable position. When the second motor 20 is damaged, the limit nut 24 can be loosened and the box 19 can be pushed by manpower to rotate the dirt suction arm”. The applicant found that such a structure has the following disadvantages:

[0004] A single limiting nut 24 cannot ensure a stable connection between the rotating platform 17 and the first fixing ring 18, and if the limiting nut 24 breaks, it is difficult to remove it.

[0005] If there are multiple limit nuts 24, although a stable connection is provided between the rotating table 17 and the first fixing ring 18, the multiple limit nuts 24 are troublesome to disassemble and assemble, which undoubtedly reduces the efficiency. Utility Model Content

[0035] The working principle and beneficial effects of the above technical solution are:

[0036] The utility model discloses an adjustable dirt suction arm for an electric dirt suction vehicle. When the dirt suction arm needs to be rotated, the motor 13 works, thereby driving the square turntable 17 and the square shaft 16 to rotate through the meshing gear 14 and the toothed disc 15, thereby realizing the rotation of the upper support seat 11 connected with the square shaft 16. When the motor 13 is damaged, after the toothed disc 15 is manually lifted, the square sleeve 18 slides upward on the square shaft 16, the toothed disc 15 is disengaged from the square turntable 17, and the toothed disc 15 is disengaged from the gear 14. At this time, after the toothed disc 15 is manually rotated, the square sleeve 18 connected with the toothed disc 15 and the square shaft 16 in the square sleeve 18 can be driven to rotate, and the square shaft 16 drives the upper support seat 11 to rotate, thereby realizing the purpose of manually rotating the dirt suction arm. The utility model provides an adjustable sewage suction arm for an electric sewage suction vehicle. When the motor 13 is damaged, it is very convenient to manually rotate the sewage suction arm. When the motor 13 drives the sewage suction arm to rotate, due to the arrangement of the square sleeve 18 and the square turntable 17, the connection between the toothed disc 15 and the square rotating shaft 16 is also very stable.

[0039] When the toothed disc 15 is manually lifted, the square sleeve 18 slides upward on the square shaft 16, and the square groove at the bottom end of the toothed disc 15 disengages from the square turntable 17. When the toothed disc 15 falls back, the square sleeve 18 slides downward on the square shaft 16, and the square turntable 17 falls back into the square groove, thereby achieving a stable connection between the toothed disc 15 and the square turntable 17.

[0040] In one embodiment, the dirt suction assembly includes:

[0044] The drooping pipe 25 is installed at the end of the sewage suction horizontal pipe 23 away from the corrugated pipe 22.

[0045] The working principle and beneficial effects of the above technical solution are:

[0046] The extension and retraction of the sewage suction transverse pipe 23 on the upper support seat 11 is realized by the expansion and contraction of the bellows 22, thereby realizing the control of the expansion and contraction length of the hanging pipe 25, and the sewage suction pump 21 works to realize the sewage suction operation, and the hose 24 located at the rear end of the upper support seat 11 realizes the sewage collecting operation.

[0048] A screw rod 26, both ends of which are connected to the bottom end of the upper support seat 11 through a mounting frame;

[0049] The screw sleeve 27 is sleeved on the screw rod 26;

[0050] A transverse groove 28, which is formed at the bottom end of the upper support seat 11 and communicates with the action chamber 20;

[0051] The limiting plate 29 has one end connected to the sewage suction transverse pipe 23 , and the other end of the limiting plate 29 is penetrated by a transverse groove 28 and connected to the screw sleeve 27 .

[0052] The working principle and beneficial effects of the above technical solution are:

[0053] The screw rod 26 at the bottom end of the upper support seat 11 rotates, and the screw sleeve 27 sleeved on the screw rod 26 drives the limit plate 29 to slide along the transverse groove 28, thereby driving the sewage suction transverse pipe 23 connected to the limit plate 29 to move horizontally in the action chamber 20, thereby realizing the control of the telescopic length of the drooping pipe 25.

[0059] In one embodiment, a rigid block is embedded in the square turntable 17, and a magnetic block adapted to the rigid block is installed on the inner wall of the square groove.

[0060] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
