Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, specifically to an internal spraying device for a multi-nozzle equipment with adjustable spray angle. Background Technology

[0002] Cleaning hardened concrete residue from the inner walls of cement mixer trucks and other equipment during routine maintenance has always been a significant challenge. Traditional cleaning methods rely primarily on manual labor: operators must enter the tank through narrow access holes and, in a confined, poorly ventilated environment, especially in the high temperatures of summer, use hand tools to knock and scrape away the hardened lumps.

[0003] This traditional method of operation has significant drawbacks: First, working inside the tank poses major safety risks such as suffocation and heatstroke; second, the space inside the tank is small and the distribution of the stirring blades is complex, making manual cleaning not only labor-intensive and inefficient, but also prone to causing scratches or bumps to personnel; finally, manual cleaning is difficult to reach areas such as the back of the blades and the dead corners at the bottom of the tank, resulting in poor cleaning effects.

[0004] Therefore, there is an urgent need for a device that can be operated from outside the tank, automatically penetrate into the tank, and perform efficient and comprehensive spraying and cleaning of complex curved surfaces and dead corners, so as to completely replace dangerous manual tank entry operations. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a multi-nozzle equipment cavity spraying device with adjustable spray angle, which can safely and efficiently complete the comprehensive spraying operation on the interior cavity of complex equipment such as cement mixer truck tanks, fundamentally avoiding the risk of personnel entering confined spaces.

[0006] To address the aforementioned problems, the present invention provides an adjustable spray angle multi-nozzle equipment internal cavity spraying device, comprising a bracket, a spray cylinder, an adjustable nozzle, a spray angle adjustment unit, and a spraying agent unit; One end of the bracket is fixedly connected to the spray cylinder, and the two sides of the bracket support the spray angle adjustment unit and the spray tank that is connected to the adjustable nozzle through the spray cylinder; The spray angle adjustment unit includes a sliding sleeve, a gasoline engine, and multiple outer umbrella ribs; the sliding sleeve is axially slidably mounted on the circumferential outer wall of the spray tube; one end of the outer umbrella rib is hinged to the sliding sleeve, and the other end of the outer umbrella rib is hinged to support the adjustable nozzle; the gasoline engine is fixed on one side of the bracket, and the power output end of the gasoline engine is hinged to support the sliding sleeve and provide axial reciprocating sliding power to the sliding sleeve, which is then converted into the umbrella-shaped opening and closing power of the adjustable nozzle.

[0007] Preferably, the adjustable nozzle includes multiple flexible nozzles and multiple inner umbrella ribs; one end of the flexible nozzle is fixed and connected to the spray cylinder, and the multiple flexible nozzles are evenly distributed around the outer periphery of the end of the spray cylinder; one end of the inner umbrella rib is hinged to the end of the spray cylinder, and the other end of the multiple inner umbrella ribs is respectively hinged to the middle of the multiple flexible nozzles.

[0008] Preferably, the sliding sleeve includes a main sliding sleeve and a secondary sliding sleeve arranged axially at intervals, and the axial ends of the main sliding sleeve and the secondary sliding sleeve facing each other are fixedly connected by a connecting rod; the circumferential outer wall of the main sliding sleeve is hingedly supported by the power output end of the gasoline engine; the circumferential outer wall of the secondary sliding sleeve is hingedly supported by multiple outer umbrella ribs, and the multiple outer umbrella ribs are respectively hingedly connected to the middle of multiple flexible nozzles.

[0009] Preferably, all inner umbrella ribs are telescopic rods.

[0010] Preferably, the spray unit includes a spray box and a spray hose, wherein the inlet end of the spray hose is connected to the spray box, the outlet end of the spray hose is connected to the spray cylinder, and the fixed connection position between the spray hose and the spray cylinder is located at the axial interval between the main sliding sleeve and the auxiliary sliding sleeve.

[0011] Compared with the prior art, the advantages and technical effects of the present invention are as follows: The present invention discloses an adjustable spray angle multi-nozzle equipment internal cavity spraying device. A gasoline engine drives a sliding sleeve to reciprocate axially, which in turn drives a flexible nozzle to perform an umbrella-shaped inward / outward reciprocating spraying action via an outer umbrella rib. The sliding and telescopic inner umbrella rib provides inner circumferential support for the flexible nozzle and, in conjunction with the outer umbrella rib's external support, prevents the flexible nozzle from uncontrollably swaying and bending during high-pressure spraying. This enables controllable adjustment of the flexible nozzle's spray angle. Specifically, by adjusting the gasoline engine's stroke, the maximum displacement of the sliding sleeve towards the two axial ends is controlled, thereby controlling the maximum opening spray angle and minimum closing spray angle of multiple meat aroma nozzles.
