Problems solved by technology

In the prior art, the cable and the rod connected to the vibrating rod and the controller cannot be easily and conveniently disassembled. In actual use, if the cable is damaged, it needs to be repaired together with the vibrating rod, so that the small problem that the user can repair becomes only a professional. The big problem of maintenance personnel can not only bring inconvenience to use, but also increase the maintenance cost

Embodiment 1

[0024] like figure 1 As shown, a plug-in concrete vibrator with a built-in motor provided by the present invention includes a power cord 1, a controller 2, an external connection cable 3, a connection assembly 4, a rubber hose 5 inner connection cable, a rubber hose 5 and a vibrating rod 6. The controller 2 draws out the power cord 1 and the external connection cable 3 respectively, the power cord 1 of the controller 2 is connected to the power supply, and the external connection cable 3 is connected to the rubber hose 5 and the connection cable in the rubber hose 5 through the connection assembly 4, The rubber hose 5 and the connecting cable in the rubber hose 5 are connected to the vibrating rod 6; the rubber hose 5 is used for hand-held operation, and the connecting cable is used for electrical connection between the controller 2 and the vibrating rod 6.

[0025] vibrator 6 as figure 2 As shown, it includes a housing 7, an eccentric block 8, a built-in motor 9, and a sea...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 lies in that the connection assembly 4 adopts an existing conventional structure, and other structures are the same as Embodiment 1.

Embodiment 3

[0032] The difference between this embodiment and Embodiment 1 is that the sealing assembly 10 adopts the existing conventional structure, and other structures are the same as Embodiment 1.

Abstract

The invention provides an in-built plug-in concrete vibrator of a motor. The in-built plug-in concrete vibrator of the motor is characterized in that a stator of the built-in motor is formed by installing, winding and splicing three iron cores laminated by the same punches, and each iron core only has one tooth. The in-built plug-in concrete vibrator of the motor solves the production problem of products which are different in size, specification and voltage level, specially 380-v products; and thoroughly solves the problem of off line of the built-in motor, wherein the off line speed of the built-in motor is improved by more than 10 times compared with the prior art; processing yield rate of the products is improved to 99.5% from 85%; full rate of a motor tank is improved to 80% from 40%, space utilization rate is obviously improved, wire diameter of a winding is thickened, thermal load is reduced, power density of the motor is improved by more than one time compared with the prior art, and force output and reliability of a vibration rod are better; simultaneously, the problem of lead sealing in the prior art is solved; and service life of a cable is improved, and the problem of maintenance and replacing of connection cables of the products is solved.

Description

technical field [0001] The invention relates to a plug-in concrete vibrator with a built-in motor, which is used for construction engineering and belongs to the technical field of construction machinery. Background technique [0002] Concrete vibrator is one of the necessary tools for pouring concrete. Construction industries such as building houses, roads, bridges, and water conservancy projects cannot do without it, and it is widely used. [0003] The plug-in concrete vibrator with a built-in motor overcomes most of the weaknesses of the planetary roller cone plug-in concrete vibrator with an external motor, such as high noise, short life, and high energy consumption, because there is no flexible shaft and rolling cone. The plug-in concrete vibrator built into the electronically driven motor also has the advantage of light weight. Its total weight is only a few kilograms, which greatly reduces the labor intensity of the operator. But it has the fatal weakness that the sm...
