Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art all belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the automatic feeding device for manufacturing the concrete sample comprises a hopper 1, a bracket 2, an electromagnetic valve 3, a pump 4, a floating iron plate 5, a turntable 6, a turntable motor 7, a vibration motor 8, a sample mold 9 and a base 10.

In this embodiment, hopper 1 adopts the conical iron bucket of inversion, fixes above support 2 through the welded mode, and the below of hopper 1 is connected with pump 3 and solenoid valve 4, and the concrete in hopper 1 passes through solenoid valve 3 after the pressurization of pump 4, and then carries in test piece mould 9 through the pipeline.

A floating iron plate 5 is horizontally and fixedly arranged on the bracket 2, and the floating iron plate 5 extends out of the bracket 2.

Further, a low-speed motor is selected as the turntable motor 7, and the rotating speed of the turntable motor 7 is set to be 1 revolution per minute; a turntable motor 7 is fixedly arranged on a base 10, a rotating shaft of the turntable motor 7 is vertically upward, and a turntable 6 in a disc shape is fixedly arranged on the rotating shaft of the turntable motor 7, so that the turntable 6 can rotate along with the turntable motor 7.

A plurality of uniformly distributed grooves are formed in the edge of the turntable 6, and a plurality of test piece molds 9 are placed on the grooves; the size of the groove is matched with that of the test piece mold 9, so that the test piece mold 9 can be just clamped in the groove and rotates along with the turntable 6; preferably, the specimen mold 9 is a square mold with an open top.

The vibrating motor 8 is fixedly installed in the center of the rotary table 6, and when the vibrating motor 8 is started, the square test piece mold 9 on the rotary table 6 vibrates together, so that concrete in the test piece mold 9 is tamped.

It is worth to be noted that the base 10, the turntable 6, the turntable motor 7, the test piece mold 9 and the vibrating motor 8 are relatively fixed as a whole; the hopper 1, the bracket 2, the electromagnetic valve 3, the pump 4 and the floating iron plate 5 are relatively fixed into a whole. Therefore, when the two parts are placed on a horizontal plane, the troweling iron plate 5 and the test piece mold 9 on the rotating disc 6 can be aligned in the vertical direction when the rotating disc 6 rotates, and simultaneously, the lower edge of the troweling iron plate 5 and the test piece mold 9 on the rotating disc 6 are just contacted. Therefore, when the rotary table 6 rotates, the troweling iron plate 5 can trowel the redundant concrete on the test piece mold 9 and trowel the concrete in the test piece mold 9.

Further, the electromagnetic valve 3, the pump 4, the rotating motor 7 and the vibrating motor 8 are electrically connected by adopting an STM32 embedded single chip microcomputer, so that the electromagnetic valve 3, the pump 4, the rotating motor 7 and the vibrating motor 8 can be controlled by the STM32 embedded single chip microcomputer; of course, the switches of the electromagnetic valve 3, the pump 4, the rotary motor 7 and the vibration motor 8 can also be directly controlled by hand.

When the automatic feeding device for manufacturing the concrete test piece works, firstly, concrete to be tested is added into a hopper 1, then, switches of an electromagnetic valve 3 and a pump 4 are opened, the concrete in the hopper 1 enters a test piece mold 9 on a turntable 6 through a pipeline, after the concrete in the test piece mold 9 is filled with concrete and slightly overflows, the switches of the electromagnetic valve 3 and the pump 4 are closed, a switch of a rotating motor 7 is opened, the turntable 6 is rotated, and concrete injection is carried out on the next test piece mold. After the test piece molds of the required number are filled with concrete or all the test piece molds on the rotary table 6 are filled with concrete, the vibration motor 8 is turned on to tamp the concrete in the test piece molds 8 by vibration, the vibration motor 8 is turned off after tamping, and then the rotary table motor 7 is turned on to enable all the test piece molds 9 to rotate to the position below the troweling iron plate 5 along with the rotary table 6 to carry out troweling operation.
