Detailed Description

Referring to a new suction nozzle body assembly 100 of a sanitation vehicle shown in fig. 1, the apparatus can be used for a sanitation vehicle, generally disposed at the rear of the sanitation vehicle, for cleaning the street while the sanitation vehicle is moving. It comprises an integrally formed suction nozzle body device main body 108 of the sanitation vehicle; at least two driven wheels 114 for supporting the sanitation vehicle suction nozzle body to move are arranged on the sanitation vehicle suction nozzle body device main body; in fig. 1, a total of four driven wheels 114 are included, and these driven wheels 114 support the weight of the entire sanitation vehicle nozzle body assembly 100 in ground contact during the operation of the sanitation vehicle. The driven wheel is connected to the nozzle body assembly body 108 of the sanitation vehicle via a tire securing structure 114.

The device body 108 includes a first surface 402 close to the ground and a second surface 404 remote from the ground (see fig. 4). The first surface 401 is adapted to be placed adjacent to the floor and dirt and water from the floor passes through the cavity provided in the first surface 402 into the conduit 102 on the second surface, which conduit connects the vacuum connection of the vacuum line 102 to an external vacuum source. The vacuum tube is detachably fixed on the suction nozzle body device main body of the sanitation vehicle, the vacuum connecting tube can be damaged after being used for a long time, and the vacuum connecting tube can be replaced through the detachable device.

Referring to fig. 2, a swing arm water spray structure 200 is shown. The swing arm water spray structure 200 swings along a certain angle to form a larger cleaning range in the running process of the sanitation truck. The swing arm water spraying structure comprises a swing arm 208 and a water spraying pipe 210 fixed on the swing arm 208. The swing arm is connected to the driven wheel extension 112 by a pivot 202. The second surface 404 includes a vacuum baffle 310 extending from the main body 108 toward the ground, the vacuum baffle 310 enclosing a vacuum chamber 316 capable of transporting the dust therein to a vacuum connection pipe; the driven wheel extending structure is also fixed with a swing arm driving device 220, the swing arm driving device is a cylinder driving device 220, and a driving rod 218 of the cylinder is connected with the pivot 202 end of the sprinkling swing arm. The cylinder drive rod 218 is pivotally connected to a crank (not shown) at the end of the pivot 202 so that reciprocating motion can swing the swing arm 208.

A resetting device fixing frame 206 is arranged outside the swing arm 208, and a fixing hole 205 is arranged on the fixing frame 206. A return spring 204 is fixed to the fixing frame 206 through the fixing hole. The other end of the tail spring is fixed to the projecting structure 112. Thus, when the swing arm 208 swings outward, the spring is tensioned, and when the air cylinder is released, the spring automatically pulls the swing arm back to reciprocate.

In other preferred cases, the drive device can also be any other type of drive device. For example, a servo motor is connected with the control circuit to control the reciprocating motion of the controller.

The swinging process in the swinging process of the swing arm can cover a larger cleaning range, and a better cleaning effect is obtained.

Referring to fig. 3, fig. 3 is the back of fig. 2 showing a first surface. The first face includes a vacuum barrier 310 extending from the main body towards the ground, the vacuum barrier 310 enclosing a vacuum chamber 318 capable of transporting dust from the interior thereof into the vacuum nozzle 102.

The vacuum baffles 310 include four vacuum baffles 310 extending outward in four directions, front, back, left and right. The vacuum barrier 310 is, in effect, spaced from the ground during operation of the sanitation vehicle to allow external air to enter the vacuum chamber 318 defined by the vacuum barrier, which vacuum will assist in absorbing dust from the ground.

The vacuum chamber 318 is divided into a water spray chamber 308 and a dust suction chamber 316 by a partition plate provided therein. The water spray cavity is internally provided with a plurality of spray heads 304 which are arranged along the extending direction of the water spray cavity. A plurality of spray heads 304 through which a high pressure water source connected to a water source by a pipe is sprayed.

The partition 312 is provided with at least one through hole 302 for allowing air and water to enter the dust suction chamber 316 from the water spray chamber 308, and during dust suction, the water sprayed from the water spray head 304 carries dust and enters the waste water collection system of the sanitation truck through the vacuum connection pipe 102 under the negative pressure of the dust suction chamber 316. The water in the wastewater collection system is sprayed out from the spray head of the water spraying cavity 308 through the filtering and high-pressure equipment, so that the water can be recycled and saved.

Refer to fig. 3 and 4. The vacuum nozzle 102 is connected to a channel 320 at the opening of the second side, and the channel 320 is disposed in the suction chamber of the second side and protrudes from the first side to the second side. The height of the section of the flow guide groove is gradually reduced from the vacuum connecting pipe to two sides. And gradually decreases to a lowest level at a location 324 where the two channels communicate.

During the operation of the sanitation truck, the suction force generated by the vacuum source enables air in the dust suction cavity 318 to enter the vacuum connecting pipe 102, the air enters the dust suction cavity 316 from the water spraying cavity 308, water in the water spraying cavity 308 flushes the ground, the flushed water passes through the through holes in the partition plate and enters the dust suction cavity 316, and the water in the dust suction cavity enters the vacuum connecting pipe.
