Corn straw has the highest value.In recent years, along with the fast development of animal husbandry, the problem of animal feed shortage is day by day serious, is particularly acute in the winter time.In China rural area, corn straw has long history as animal feed, but corn straw mostly uses manual type when gathering in the crops, and labor intensity is big.Sometimes in order to plant winter wheat in quickly, peasant to straw often on-site incineration, had both destroyed the organic matter in soil and microorganism after harvesting corn fruit ear, makes the hardening soil, soil fertility decline, wastes again a large amount of stalk resource simultaneously.
Corn harvester for silage tool is to improve silagecorn feed quality and the important measures developed animal husbandry.The self-propelled silage harvester that now various countries use, mostly by the ceding of Taiwan, intake mechanism, shredding mechanism, knife sharpening device, throw the parts such as mechanism and form.Wherein knife sharpening device plays important assosting effect in complete equipment.When ensilage machine workload reaches to a certain degree, the moving knife blade on the cutting roller in shredding mechanism there will be abrasion in various degree, causes material cutting quality poor, and during chopping, vibrations increase, and needs to whet a knife.If being taken off one by one by the moving knife on cutting roller and carrying out sharpening, complex operation is time-consuming, it will being delayed the activity duration, work efficiency is substantially reduced.
Have on present equipment to be equipped with and manually whet a knife and the form of automatic grinding, it is to avoid the dismounting of moving knife improves simple operation simultaneously.Lower than the mode efficiency of automatic grinding because manually whetting a knife, and need artificial participation, inefficient, and external automatic grinding the whole series structure and control system are complicated, and it is relatively big to manufacture difficulty of processing, cost is the highest.Making a general survey of domestic ensilage machine, whetting a knife to be still in the case of j ob impact is relatively big or just pulled down by moving knife after the operation season carries out sharpening, and efficiency is the lowest.Therefore it is badly in need of a set of simple in construction, and is easily achieved the knife sharpening device automatically controlled.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above, it is provided that a kind of silage harvester automatic knife-grinding apparatus.For improving the sharpening efficiency realizing precise and high efficiency, propose a kind of on-line automatic knife sharpening device that need not dismantle, and its simple in construction easily is automated control, is greatly improved work efficiency.
The technical solution of the utility model is as follows: a kind of ensilage machine automatic knife-grinding apparatus, described ensilage machine includes that left plate and right plate, described knife sharpening device include horizontal conveyor device, hone sleeve, hone, slide block, guide rail, guide rail fixed block;
The two ends of described horizontal conveyor device are separately fixed on left plate and right plate, the two ends of described guide rail are fixed on left plate and right plate by guide rail fixed block, described slide block is installed on guide rail, the both sides of hone upper cartridge are connected with slide block and horizontal conveyor device respectively by bolt, and hone is installed on the bottom of hone sleeve.
Further, described horizontal conveyor device includes motor, shaft coupling, leading screw support, ball screw and feed screw nut;The two ends of described ball screw are arranged on left plate and right plate by leading screw support respectively, and feed screw nut is arranged on ball screw, and shaft coupling and motors are passed through in one end of ball screw, and the top of hone sleeve is connected with feed screw nut.
Further, described knife sharpening device also includes proximity switch and controller;Described proximity switch is arranged on one end of guide rail;Proximity switch is connected with controller, controller and motors.
The ensilage machine of a kind of automatic grinding, including cutting roller and above-mentioned ensilage machine automatic knife-grinding apparatus, described ensilage machine automatic knife-grinding apparatus is arranged on above cutting roller, and hone contacts with cutting roller moving knife.
This utility model has the beneficial effect that
1, roller screw is with motor as an independent power unit, can individually control, and does not interfere with each other with other elements.
2, by proximity switch and controller and the closed loop control of motor, sharpening position, the control of reciprocating motion number of times of whetting a knife can accurately be realized, it is easy to accomplish Automated condtrol.
3, package unit simple in construction, manufactures difficulty of processing little, reduces cost.
4, the device avoids the moving knife dismantled on cutting roller one by one and carry out sharpening, improve work efficiency.
