The invention discloses a four-shaft united excitation vibration power device. The four-shaft united excitation vibration power device comprises a box body; a first main shaft, a first driven shaft, asecond driven shaft and a second main shaft are sequentially installed in the box body side by side; a first driving gear and a second driving gear are installed on the first main shaft and the second main shaft correspondingly; a first driven gear engaged with the first driving gear and a second driven gear engaged with the second driving gear are installed on the first driven shaft and the second driven shaft correspondingly; the first main shaft and the second main shaft penetrate through the box body and are connected with a driving device; first eccentric blocks are installed on the first main shaft; and second eccentric blocks are installed on the second main shaft. According to the four-shaft united excitation vibration power device, the driving device drives the first eccentric blocks and the second eccentric blocks installed at the two ends of the first main shaft and the second main shaft to rotate to generate vibration; due to the fact that the first main shaft, the secondmain shaft, the first driven shaft and the second driven shaft are installed side by side, the contact area with a vibration table is increased, the needed vibration time is shortened, the amplitude is reduced, and the needed excitation vibration force is convenient to adjust due to the design of the eccentric blocks at the two ends.

The invention discloses an impact force testing device, which comprises an external power supply and a displaying device, wherein the external power supply is connected with the displaying device; the impact force testing device is characterized by comprising a cylinder body (2), wherein a holding cavity with a bottom and without a top is arranged in the cylinder body (2), and a rubber leather bowl (4) is arranged on the upper end of the holding cavity; a piston (5) is arranged on the rubber leather bowl (4); an upper cover (6) is arranged on the upper end of the cylinder body (2); a damping hole plate (3) is arranged in the holding cavity, and the damping hole plate (3) is used for dividing the holding cavity into a holding cavity I (21) and a holding cavity II (22) from top to bottom; and a sensor (8) is arranged on the side wall of the cylinder body (2), and the sensor (8) is connected with the external power supply and in signal connection with the displaying device.

The invention provides a concrete brick forming machine with good synchronization and low noise, comprising a synchronous pressing head mechanism for realizing synchronous pressing of bricks, a concrete brick mould frame arranged under the synchronous pressing head mechanism, and a concrete brick mould frame connected to the concrete brick mould frame. The lower end is used to transmit the vibration force directly to the vibration transmission connector of the concrete brick formwork frame, the vibration mechanism fixed on the vibration transmission connector to provide the vibration source, the concrete brick support plate set at the bottom of the concrete brick formwork frame, The vibration damping and knocking support mechanism arranged under the concrete brick support plate for supporting the concrete brick support plate and the lifting mechanism for driving the concrete brick formwork frame and the vibration transmission connecting piece to move up and down together. The advantages of the invention are: good synchronization, good brick-making effect; good vibration and compaction effect of filler, which can ensure the quality of formed concrete bricks and improve product qualification rate; low working noise of the whole machine is beneficial to protect the health of workers; High-efficiency and high-volume production can be achieved.
