The technical field is as follows: sweeper, emergency ambulance, patrol vehicle and fire truck

Background art: mechanical sweeper has become an indispensable cleaning tool for modern high civilization human urban road squares. But the existing sweeper has serious defects and extremely poor efficiency: the cleaning speed is less than 5 kilometers, and the water and dust are continuously sprayed, so that the wet fallen stones and large parts of the piled garbage pavement cannot be swept, and even if the floating dust is generated, the water is firstly sprayed into slurry to be spread on the ground, so that the sweeping cannot be carried out. The dust absorption type principle has large energy consumption and low efficiency, can only be charged by frequently filling water or directly adopts a highly-polluted fuel locomotive mode, and can only carry out low-efficiency cleaning with too little actual effect and almost door surfaces after early-stage manual cleaning, thereby not only increasing road congestion, but also having no other beneficial functions. And the price is poor, the quality is high, a plurality of wearing parts are needed, the replacement is frequent, and the use is inconvenient.

The invention content is as follows: the sweeper is improved, so that all the capabilities of the sweeper are harder, small piles of garbage and rock on the ground are swept, and the sweeper is easy, efficient and extremely safe. And can be pushed manually or completely electrically, and can efficiently purify the road surface square in a high-speed flying anhydrous dust removal mode. The core technical principle is that the combined type crawler belt cleaning and airflow blowing ground are realized, the improvement is that the sweeping blades are all made into a composite mode of a rigid framework, a movable integral blade, an outer edge brush and the like, the maximum sweeping width, the maximum accommodating space, the simplest and cheapest reliable transmission and high-speed sweeping dust removal mode are ensured, all garbage on the ground can be swept efficiently and all-round, and the basic structural characteristics are as follows:

1. the cleaning brush track is provided with a proper amount of horizontal rigid frames vertical to the belt surface, the outer ends of the horizontal rigid frames or the outer ends of the blades are connected with the horizontal hairbrush strips, and the rigid straight rods can be made into a vertical automatic telescopic structure in a pressure spring sliding sleeve mode and the like. The two sides can be arranged in a row uniformly, and the two sides can be weighted to ensure that the middle part has the largest accommodating cavity. The thin strip brush mainly takes flexibility, and can be integrated with the blade and the frame. The bottom edge pin bush of the movable blade of the transverse long pin bush can be also manufactured at the bottom of the rigid frame, so that the light blade can integrally rotate to be vertical or lie down to form an airflow channel, the flexible blade is waterproof and anticorrosive and is easy to deform, the flexible blade is more suitable for sweeping and containing soft and hard garbage of various sizes, and the collection of hard and large stones and small ground piled garbage is easy. When cleaning, the brush track scrapes the face of sweeping the floor forward with about 2 times speed that move ahead under front and back roller track (or rear portion gyro wheel) contact transmission, and the air current is less when the blade is the screen cloth material, otherwise the air current is great must strictly seal: the lower parts of the two side plates are sleeved with the brush hair vertical plates in a sliding way in a vertical sliding way such as a multi-point pin clamping groove, the lower edges of the two side plates are sealed in a grounding way by dense (better backward bending type) brush hair, the larger plate surface forms natural blocking, and the two side plates, the rear lower baffle plate (flexible and lower edge with hair) and the front end roller track form dynamic sealing together to prevent dust leakage.

2. At least the front end landing roller is divided into three sections, the middle section is directly softened, thinned or completely cancelled (only a middle shaft is left), or two ends form an upward crankshaft whole by a middle inclined upper sliding sleeve and can be connected with a side plate to be reinforced, the middle section is inserted into two side sliding sleeves by two side upward sliding rod frames to form a middle lifting roller body, so that the middle lifting roller body can be automatically lifted when meeting a large pile of garbage hard objects, the upper roller and the rear cleaning roller can also adopt the three-section middle section cancellation, thinning and softening (adopting high-elasticity materials) as appropriate, a sliding mode (up-down or front-back direction) is added with a high-elasticity and flexible crawler belt, thereby ensuring smooth and reliable storage of large parts, over-hard cleaning efficiency and easy storage of small piles. Two concave-convex alternate uniform clamping structures can be correspondingly arranged on the inner surfaces of the rollers on the two sides and the crawler belt, so that the crawler belt can be prevented from deviation and dislocation.

3. The front edge adopts a dynamic or static retractable and telescopic inclined scraping brush structure, the inclined type not only means that the scraping brushes on two sides are arranged in an inverted splayed inclined mode, but also the brush hair direction is inclined backwards with the brush rod or the brush holder, so that the brush hair can form a large-scale side surface pressing contact high-efficiency scraping, sweeping and piling movement effect with the ground, the efficiency is high after the brush is matched with a high-elasticity stainless steel wire, dust is not raised even at high speed, the necessity and the cost of water spraying are thoroughly eliminated, a high-pressure pump, a hydraulic motor and the like are completely omitted, and the cost is greatly reduced. The scraping brush can also be made into a friction (ground) wheel and is scraped by conical rotation driven by a flexible shaft, so that the scraping brush is more suitable for slow cleaning by walking and pushing. The multi-row telescopic scraping brush with the tension springs stretched and mutually clamped and sliding is adopted, so that the scraping area and the road surface avoidance can be controlled at any time in the modes of pulling and releasing the pull rod handle, and the like, and the multi-row telescopic scraping brush is simple, practical, flexible and convenient.

4. For small handcart type, the whole vehicle can be simplified into only one pair of middle and rear wheels, and the front part can be stopped from being lifted off the ground for normal walking movement by pressing down the handle. The electric type is best to place the steering driving wheel in the middle, two small electric fans are separately arranged on two sides (only one electric fan is opened to reduce the air volume by half), and two universal wheels are separately arranged on the rear part of the electric fan, so that the steering is very flexible. The middle shaft of the steering driving wheel fork is provided with a sleeve type vertical shaft structure, so that a vehicle body can be lifted by a concentric screw rod, a side rack and various methods to lift a front roller off the ground, or a rear universal wheel can be lifted to a large extent, and cleaning can be stopped at any time to carry out conventional movement. The steering pull wire of the steering driving wheel is connected with the lower edge of the handle shaft rod at one side from the bottom edge of the carriage, and the driver seat is hinged, fixed, movable and overturned towards the one side, so that a larger space with the middle part penetrating through the front and the back is obtained, and the stretcher can be used for temporarily stopping a pair of conventional stretchers, thus being capable of rescuing and transporting wounded in a short way in an emergency. Because the sweeper runs on streets in densely populated urban areas day and night for a long time without rest, the sweeping is extremely simple work in a sealed state without dust, daily sweeping, patrol, fire fighting and first aid are integrated, the sweeper is convenient, easy, efficient and reliable, an oxygen bag, a cardiac needle, a fire extinguishing bomb and a small amount of first aid equipment are carried along with the sweeper, and the sweeper can achieve multiple effects at a stroke and simply and easily by matching workers with necessary technical skills for public security, emergency disinfection and fire fighting, and can more reliably and effectively benefit human beings.
