The invention discloses a pavement seam filling
machine for conveniently adjusting the size of the seam filling, which comprises a push
handle, a battery box, a control panel, a
drive motor, an electro-hydraulic rod and a protective tarpaulin. The lower end of the push
handle is fixed with a
cart main body, and Universal wheels and moving wheels are installed on the lower side of the main body of the
cart, a battery box is fixed above the main body of the
cart, and a control panel is connected to the upper end of the battery box, and a
discharge bucket is fixed above the main body of the cart. And the upper end of the discharging
barrel is provided with a
bung, the
drive motor is installed inside the lower end of the discharging
barrel, and the bottom of the discharging
barrel is provided with a maintenance port. The pavement caulking
machine that is convenient to adjust the size of the caulking can change the size of the caulking material plate in a rhombic structure through the expansion and contraction of the electro-hydraulic rod, so that the internal
transverse dimension of the frame composed of the caulking material plate can be changed, so that the caulking material can be filled. The size of the frame composed of the seamed boards can meet the cracks of different sizes, which increases the applicability of the device.
