Detailed ways

The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. ``

As shown in Fig. 1 and Fig. 2, a kind of ramming machine with double crank rocker mechanism, comprises ramming machine main body, crank rocker mechanism and tamper block device; Described ramming machine main body is provided with wheel 1, Handle 2, carriage main body 3, fixed seat 4, guide plate 14 and motor support seat 11, wheel 1 is arranged under carriage main body 3, handle 2 is arranged on the left side of carriage main body 3, handle 2 and carriage main body 3 are connected by welding , the fixed seat 4 is arranged in the middle position of the inner left part of the carriage main body 3, and the interior of the carriage main body 3 is also provided with a motor support seat 11, and the guide plate 14 is arranged on the right part of the carriage main body 3, and the guide plate 14 is provided with a square gap 19; The crank and rocker mechanism is provided with a rocker 6, a slider 7, a crank 9, a drive motor 10 and a connecting arm 13, the rocker 6 is connected to the fixed seat 4 through the first connecting pin 5, and the middle part of the rocker 6 is provided with a slider 7. There is a square hole 20 in the middle of the slider 7. The square hole 20 is slidingly connected to the rocker 6. The slider 7 is connected to the crank 9 through the second connecting pin 8. The lower end of the crank 9 is connected to the drive motor 10. The drive motor 20 is set On the motor support base 11, the right end of the rocking bar 6 is provided with a U-shaped notch 21, the connecting arm 13 is arranged in the middle of the U-shaped notch 21, and the connecting arm 13 is connected with the rocking bar 6 through the third connecting pin 12; the crank rocker mechanism It is two left and right pieces; the tamp block device is provided with a tamp block 18, a connecting plate 16 and a set screw 17, the lower end of the connecting arm 13 is connected with the connecting plate 16 through the fourth connecting pin 15, and the connecting plate 16 is connected by the set screw 17 Connect with the ram block 18, and the left end of the ram block 18 is connected with the right end of the guide plate 14.

Further, the rocker 6 is in clearance fit with the square hole 20 on the slider 7 . The clearance fit between the rocker and the square hole can effectively ensure that the rocker can move effectively in the rule that the crank drives the slide block to perform circular motion.

Further, both ends of the drive motor 10 are provided with a first rotating shaft 22 and a second rotating shaft 23 which are synchronized. There is a synchronous rotating shaft, which can effectively ensure the synchronous operation of the double crank rocker mechanism and the balance of the tamping block.

Further, the width of the square notch 19 on the guide plate 14 is larger than the width of the connecting arm 13 . The width of the square notch is larger than that of the connecting arm, which can effectively prevent the connecting arm from interfering with the guide plate during the downward movement of the mechanism during the operation of the mechanism.

When the present invention is in use, the trolley is pushed to a suitable position, the drive motor is turned on, and the drive motor drives the crank to make a circular motion. Under the action of the second connecting pin, the slider also makes a circular motion, and the rocker can be driven through the square hole. Swing up and down around the fixed seat, drive the ramming block through the connecting arm arranged on the rocker, realize the up and down movement of the ramming block, and realize the expected working effect of the mechanism.
