This application provides a detachable sweeping and suction device and a railway track bed vacuuming vehicle, including at least two sets of sweeping and suction components. Each set of sweeping and suction components includes a sweeping and suction component frame, a cleaning component, and a suction component, which are mounted on the sweeping and suction component frame. A sweeping and suction component separation device is connected to the sweeping and suction components and is used to drive the two sets of sweeping and suction components to move relative to or away from each other to change the cleaning range. A swinging suction pipe is provided, one end of which is connected to the suction component of the sweeping and suction components, and the swinging suction pipe can swing along with the movement of the sweeping and suction components. The two sets of sweeping and suction components are arranged side by side in the longitudinal direction, and can be brought together to clean the middle part of the rail, or can be separated laterally to clean both sides of the rail. The lateral movement distance can be adjusted as needed, making it suitable for various types of rails, with a wide coverage area, improving the applicability of the coal dust cleaning device, and meeting the coal dust cleaning operations of various types of sleepers.

Conventional vacuum trucks collected household waste using a vacuum pump (3a), but at the same time, foul odors (3f) were released into the outside air through the exhaust port of the exhaust pipe (3b). Therefore, the deodorizing device for vacuum trucks of the present invention eliminates odors by burning the foul odors emitted from the exhaust pipe (3a) with the engine. [Solution] The odor removal device for a vacuum truck according to the present invention eliminates odor by burning the malodorous odor (3f) emitted from the exhaust pipe (3a) of the vacuum pump (3a) in the intake pipe (3d) of the engine (3c) using a T-pipe (1) and a hose (2).

This invention provides a pure suction vacuum truck and its control method, device, and storage medium, relating to the technical field of pure suction vacuum trucks. The control method includes steps S1 to S4. S1: Determine the location of trash in front of the vacuum truck based on images captured by a camera and detection signals from radar. S2: Determine whether the trash location is within the suction area. S3: When the trash location is determined to be within the suction area, obtain the trash distribution in four zones (A, B, C, D) based on the trash location. S4: Based on the trash distribution, move the suction nozzle to one of the five suction stations (A, B, C, D, E) to position the nozzle symmetrically according to the trash distribution. The vacuum truck using this control method can adaptively adjust the position of the suction nozzle in the width direction of the vehicle body according to the distribution of trash on the road, ensuring that trash is sucked up without needing to drastically increase the suction volume, effectively improving the overall energy efficiency of the vehicle.

This invention relates to the field of anti-overflow valve technology, specifically a quick-opening anti-overflow valve with a filter screen; it includes an outer shell and a first spacer ring on the inner side of the outer shell; an air intake connector is laterally connected to the outer shell space above the first spacer ring; a flow pipe is fixedly connected downwards to the inner edge of the first spacer ring; four limiting rods surrounding the flow pipe are fixedly connected downwards to the first spacer ring; an anti-detachment ring is fixedly connected to the lower end of the four limiting rods; floats are provided on the inner sides of the four limiting rods; a filter screen cylinder is inverted on the upper surface of the first spacer ring; a second sealing ring is fixedly connected to the outer surface of the upper end of the outer shell. This invention achieves quick assembly and disassembly of the filter screen cylinder through the cooperation of the top cover, L-shaped lock, and first spring, while avoiding the problem of inconvenient disassembly caused by easy corrosion of bolt connections, saving maintenance time and improving the operating efficiency of the vacuum truck; the setting of the limiting sleeve and limiting ring ensures the stability of component operation and ensures smooth filtration and gas flow.

This utility model discloses a hose retraction device for a vacuum cleaning truck, including a base mounted on the vacuum truck. The base houses a drive mechanism, a hose retraction mechanism, and a lifting mechanism. The hose retraction mechanism includes a winding drum. The drive mechanism retracts the hose by driving the drum to rotate. The lifting mechanism includes several connecting rods for lifting the hose. The drive mechanism drives the connecting rods to rotate, causing them to impact the hose and induce vibration. This utility model achieves hose retraction by driving the drum to rotate. During this process, the continuously rotating connecting rods also continuously strike the hose, causing it to vibrate and expel surface dirt, residual water, and impurities, thus thoroughly and effectively cleaning the hose.

The present disclosure relates to a versatile vacuum truck system designed for efficient collection, transport, and unloading of organic matter. Different embodiments can support side, bottom, and front unloading or different combinations thereof, facilitated by a controllable auger. The truck can feature a side spreading system with a guillotine door and brass knife valve, allowing for precise material distribution. The system can be configured for bulk dumping or controlled spreading, making it adaptable to various agricultural tasks. The flexible design optimizes performance in diverse environments, from large-scale field applications to confined spaces, enhancing efficiency and operational control.
