Screed vibrator and paver

[0023] Figure 1 to Figure 5 Shows a screed vibrator of the present invention, including an eccentric shaft 1, a blade 2, a vibrating connection seat 4, a vibrating support seat 5, and a fixed guard plate 3. The vibrating support seat 5 is installed on the screed 9 On the plate frame 7, the eccentric shaft 1 is horizontally arranged in front of the plate frame 7, and is supported on the vibrating support base 5. The upper end of the vibrating connecting base 4 is cylindrical, and is provided with an eccentric mounting hole adapted to the eccentric shaft 1 , The lower end of the vibrating connecting seat 4 extends tangentially downward from the upper end of the cylinder to form left and right walls, and the left and right walls are connected by reinforcing ribs. The ends of the left and right walls are circular, and there are hinge holes in the circular area. , The upper end of the vibrating connection seat 4 is mounted on the eccentric shaft 1 through an eccentric mounting hole. The eccentric sleeve can be set in the eccentric mounting hole to adapt to different stroke requirements. The lower end of the vibrating connection seat 4 is hinged with a blade mounting seat 21 through a hinge hole. The blade 2 is installed on the blade mounting seat 21, and the blade 2 is slidably arranged between the fixed guard plate 3 and the bottom plate 6 of the screed, so that the blade 2 only moves up and down. This makes the vibrator constitute a crank slider mechanism. Driven by the vibrating motor, the eccentric shaft 1 is used as the power input to start rotating movement. Because the fixed guard 3 and the bottom plate 6 restrict the front and rear displacement of the blade 2, the blade is installed The seat 21 can only move in the vertical direction, so when the vibrating connecting seat 4 drives the blade mounting seat 21 and the blade 2 to move up and down, the vibrating connecting seat 4 itself will swing back and forth around the eccentric shaft 1, so the vibrating The connecting seat 4 should have a certain length, so as to ensure that the vibrating connecting seat 4 swings back and forth at a very limited angle, and does not cause additional motion interference to the eccentric shaft 1 and the screed system; the blade 2 acts as a sliding block in the fixed guard 3 and Under the restriction of the displacement of the bottom plate 6, it can only move up and down, and there will be no other impact actions in the front and rear directions, so as to avoid the harsh impact and flapping noise when the paver is vibrating, which effectively improves the working environment and improves the use of components life.

[0024] In order to improve the difficult adjustment of the vertical stroke of the traditional vibrator and the complicated installation, in this embodiment, the rear side of the vibrating support base 5 is provided with a support seat positioning boss 51, and the support seat positioning boss 51 is equipped with an adjustable The vertical adjusting device 8 for the distance between it and the upper surface of the screed frame 7 includes an adjusting screw 81, an upper adjusting nut 82 and a lower adjusting nut 83. The adjusting screw 81 vertically passes through the support The seat positioning boss 51 is fixed on the plate frame 7, and the upper adjusting nut 82 and the lower adjusting nut 83 are both threadedly connected with the adjusting screw 81, and are respectively pressed against the upper and lower ends of the supporting seat positioning boss 51. The adjustment of the upper adjusting nut 82 and the lower adjusting nut 83 on the adjusting screw 81 can move the vibrating support seat 5 up or down, and adjust the position of the lower end surface of the blade 2 relative to the bottom plate 6, so that the vibrator can be adjusted very conveniently Up and down stroke. The rear side of the vibrating connecting seat 4 is provided with a connecting seat positioning boss 41, the lower surface of the connecting seat positioning boss 41 is parallel to the upper surface of the plate frame 7, and an adjustment is provided between the connecting seat positioning boss 41 and the plate frame 7 Space, when adjusting the up and down strokes, you can easily determine the up and down displacement of the vibrating support base 5 by installing a plug gauge in the adjustment space between the positioning boss 41 of the connecting seat and the plate frame 7, so as to realize fast and accurate adjustment , It greatly saves adjustment time and reduces the difficulty of work. The front side of the vibrating support seat 5 is provided with a waist-shaped hole 52 of the support seat, and a fixing screw 53 is arranged in the waist-shaped hole 52 of the support seat. The fixing screw 53 is threaded with the front side of the plate frame 7. The fixing screw 53 can strengthen the vibration For the stability of the support base 5, when adjusting the up and down strokes, the fixing screw 53 needs to be loosened first, so that the vibrating support base 5 can move down along the waist-shaped hole 52 of the support base, and the operation is convenient.

[0025] In this embodiment, the upper part of the front side of the vibrating support base 5 is provided with two guard plate hanging holes, and the guard plate hanging holes are provided with hanging bolts. The fixed guard plate 3 includes a connecting plate 31 and a guide plate 32. The plate 32 is fixed to the lower part of the connecting plate 31 by fasteners, and the connecting plate 31 of the fixed guard 3 is hung in front of the vibrating support base 5 by mounting bolts. At the same time, the vibrator also includes a plate frame 7 installed on the screed. The front side of the tensioning protrusion 71 that can adjust the front and rear positions, the rear side of the connecting plate 31 is provided with a tensioning concave block 72 that can cooperate with the tensioning protrusion 71, and the tensioning concave block 72 is fastened to the tensioning protrusion 71, when there is a gap between the guide plate 32 in the fixed guard plate 3 and the blade 2 due to wear, by adjusting the front and rear positions of the tensioning protrusion 71, the fixed guard plate 3 can be tightened backwards so as not to As the space for the front and back movement of the blade 2 of the slider, the impact sound is avoided; the tensioning protrusion 71 and the tensioning recess 72 not only adjust the front and rear positions of the fixed guard plate 3, but also support and limit the fixed guard plate 3. The function of the position ensures that the fixed guard plate 3 will not shake due to the vibration of the screed 9.
