Description

The laser scraper

Technical field

The utility model belongs to agriculture scarification equipment, particularly the laser scraper.

Background technology

At present, the high precision large-sized land readjustment machinery that China uses mostly is imported product, and the supporting and soil property situation requirement of the actual agricultural machinery of the serviceability of imported mechanical and China etc. are differences in various degree all, and complex structure, costs an arm and a leg.The scraper structure of domestic production is the mechanical type scraper of common hydraulic regulation, and these products are commonly the Artificial Control pattern, in various degree have service behaviour instability, problems such as precision is low of leveling land.

The utility model content

The purpose of this utility model is to provide a kind of laser scraper, can level land stable work in work, the precision of leveling land height, and level land efficient height automatically by the depth of cut and the ejector dozer work of laser and the dynamo-electric perching knife of control automatically.

The purpose of this utility model is achieved in that a kind of laser scraper, be included in the hoist cylinder that perching knife is installed on the traction frame that land wheel is installed and controls by hydraulic circuit, the slave arm of the articulated symmetry of difference on the support at frame rear portion, the articulated land wheel support arm that land wheel is housed in the end of slave arm, hinged hoist cylinder on the support arm of frame, the middle part of its piston rod end and land wheel support arm is hinged, the scraper bowl side plate of symmetry is being set on the frame of both sides above the perching knife, be installed with in the horizontal concrete chute that on the scraper bowl side plate, is provided with and chute connecting plate movingly, its inboard of connecting plate of symmetry is connected with the both sides of ejector dozer respectively, ejector dozer matches with the last plane of perching knife, and constitute scraper bowl with the scraper bowl side plate of symmetry, the bearing of its arranged outside of connecting plate of symmetry is respectively with corresponding to unload native oil cylinder piston boom end hinged, the afterbody that unloads native oil cylinder is hinged on the frame respectively, at the top of frame the signal that laser pickoff is installed is being set and is accepting platform, laser pickoff is connecting the electromagnetic hydraulic pressure control valve by lead.

The course of work of the present utility model is: after utilizing laser straight line principle to measure the soil absolute altitude of several points, with its input laser generator Main Control Tank, Main Control Tank calculates difference of height after receiving signal again, the laser line spectrum of output mean value, the laser pickoff of installing at frame top converts the laser rays spectrum signal to the signal of telecommunication again in order to control electromagnetic hydraulic pressure valve seat follow-up adjustment.The work order of laser land leveling system is " high shovel is low to be filled out ", and at work, the signal of telecommunication along with after the Main Control Tank conversion starts the flow and the flow direction that electromagnetic hydraulic valve changes hydraulic oil, and hoist cylinder is regulated the depth of cut of perching knife at any time in the process of walking.The soil eminence is stored in the scraper bowl by the unnecessary soil under shoveling, and drives the native oil cylinder work of unloading when running to lower by the electromagnetic hydraulic pressure control valve, promotes the ejector dozer reclaimed soil and draw off the filling lower from scraper bowl, thereby reach the purpose that automatic control is leveled land.

The utility model is by the depth of cut and the ejector dozer work of laser and the dynamo-electric perching knife of control automatically, realize leveling land stable work in work, the precision of leveling land height automatically, soil after smooth height error amount is less than 5 millimeters, helps ploughing, harrows, broadcasts, agro-farming process operations such as filling, plant protection.Save irrigation water, can improve irrigated area, farmland water-saving rate about 40%, level land efficient height, level land efficient is more than 3 times of common scraper.
