Pneumatic concrete conveying and spraying equipment

Abstract

The invention discloses pneumatic concrete conveying and spraying equipment. The pneumatic concrete conveying and spraying equipment structurally comprises moving wheels, a pneumatic conveying box, aconnector, an accommodating groove and a control cabinet. The moving wheels penetrate through the interior of the pneumatic conveying box. The connector is welded to the outer surface of the pneumaticconveying box and communicates with the pneumatic conveying box. Concrete inside the equipment is pushed by air pressure through the control cabinet at the rear end and then can be sprayed outwards.The sprayed concrete is received by strut angles and presses middle elliptical sags inwards to enable inward concave passages to be stressed to deform and generate required buffer change by followingthe stress state of an outer layer so that the concrete can bear a certain auxiliary force to be output forward. While the concrete falls off under the action of gravity, under propelling of air pressure, a lower layer also has remaining auxiliary pushing force. Forward pressing angles can press the concrete downwards under the gravity of the concrete to make the concrete be pushed inside. When reaching a certain full capacity, the concrete can be pushed upwards, a concrete inlet is reduced. When the quantity of the concrete is reduced, the inlet can be expanded.

Description

technical field [0001] The invention belongs to the field of pneumatic equipment, and more specifically, relates to a pneumatic conveying concrete spraying equipment. Background technique [0002] When cement, sand, stone, water, etc. are mixed together and stirred evenly, the concrete formed is put into the pneumatic conveying equipment, and it is sprayed evenly to the designated position through the pipeline in the main storage cell by pneumatic force. [0003] Based on the inventor's discovery above, the existing equipment for pneumatically transporting concrete mainly has the following deficiencies, such as: [0004] The material inside the concrete forms its own weight. When it is introduced into the pneumatic conveying equipment, the center of gravity sinks to the bottom, but the pneumatic conveys the concrete to the side pipes. When the concrete reaches a certain amount and the gravity increases, its The force of the pneumatic lateral thrust will become strenuous. ...

Problems solved by technology

[0006] In order to solve the above-mentioned technology, the substance inside the concrete forms its own weight. When it is introduced into the pneumatic conveying equipment, the center of gravity sinks to the lower end, but the pneumatic conveys the concrete to the side pipes. When the concrete reaches a certain amount, the gravity is somewhat When it is increased, the force of its aerodynamic lateral thrust will become strenuous
