As a further scheme of the invention, the front side wall and the rear side wall of the recovery box are both fixedly connected with slide rails, the slide rails are connected with arc-shaped separation blades in a sliding manner, the outer sides of the arc-shaped separation blades are fixedly connected with sixth springs through fixed blocks, and the bottom ends of the sixth springs are fixedly connected to the tops of the compacting plates; the during operation, because suction tube sliding connection is in the second spout, when the collection box shakes from top to bottom along with the compacting plate, concrete in the collection box can flow out in the second spout, be unfavorable for the recycle of concrete, there is the arc separation blade through sliding connection in the second spout outside, the arc separation blade laminates the bottom at the suction tube all the time under the effect of sixth spring, shake the messenger from top to bottom when the collection box, the laminating suction tube in arc separation blade top, and at compression sixth spring, the cooperation collection box slides from top to bottom, seal the second spout all the time, prevent that the concrete of retrieving from flowing out in the second spout, the concrete that leads to retrieving is extravagant.
As a further scheme of the invention, a third chute is formed in the front side of the bottom of the compacting plate, a second scraper is connected in the third chute in a sliding manner, a plurality of linear-array second springs are fixedly connected to the top of the second scraper, and the top ends of the plurality of second springs are fixedly connected to the side wall of the second chute; the during operation, because the compacting plate shakes from top to bottom under the effect of flower type cam, when the compacting plate rebound, the surface of compacting plate bottom surface concrete can not laminate completely, can not strickle off the concrete, through having seted up the third spout in the compacting plate bottom, sliding connection has the second scraper blade in the third spout, when the compacting plate rebound, the second scraper blade laminates on the concrete surface all the time under the effect of second spring, the second scraper blade is strickleed off the concrete surface all the time, guarantee that the compacting plate can both strickle off the concrete at every moment.
As a further scheme of the invention, positioning plates are fixedly connected to the front and the back of the bottom of the mounting rack, and jacks are formed at the bottoms of the two positioning plates and the top of the second connecting plate; during operation, because work is accomplished the back cylinder and is promoted the lifting plate, mention first scraper blade and compacting plate, the more facility in bottom is mentioned all the time to the cylinder, the fragile cylinder, through position fixedly connected with locating plate around the mounting bracket bottom, after the work is accomplished, the cylinder is mentioned the facility in bottom, the team of inserting on second connecting plate and the locating plate is in same level, utilize the bolt to insert second connecting plate and locating plate, the facility in location bottom, the cylinder of relaxing, the cylinder need not to promote the facility in bottom all the time, delay cylinder life.
Compared with the prior art, the invention has the beneficial effects that:
1. according to the invention, the excessive concrete scraped by the first scraper is sucked into the recycling box through the suction machine, the concrete is rapidly stirred and scraped by the scraper plate, so that the concrete is rapidly and uniformly distributed in the recycling box, the excessive concrete flows out of the discharge hole, the groove of the scraped concrete is filled, the phenomenon of material shortage is avoided, and the filled concrete is vibrated and compacted by the compacting plate, so that the concrete is firmly and smoothly laid on a road surface.
2. According to the invention, the grinding plates are driven to move together when the compacting plate moves, the bottoms of the grinding plates are always in contact with the surface of the concrete, the concrete flowing out of the discharge holes is scraped and guided, the filled concrete can reach all positions on the surface of the concrete under the simultaneous guidance of the plurality of grinding plates, the filled concrete can quickly reach the grooves of the concrete at the bottom by the aid of the grooves, the grooves are filled, the grinding plates are ejected and fixedly connected with the fifth springs, the fifth springs fix the grinding plates and apply downward pressure to the grinding plates to compact the concrete at the bottoms of the grinding plates, so that the filled concrete is quickly scraped and dispersed, the filled concrete is quickly filled to the grooves of the scraped concrete, and the quick paving of the concrete is facilitated.
