Detailed description of the invention
As shown in Figures 3 to 5, the utility model comprises frame 5, leading screw 6, supporting leg 7, roller 71, feed screw nut 8, support bar 9 and scraper plate 10, is described the utility model below in conjunction with accompanying drawing.
As shown in Figure 3, the two ends, left and right of cylinder 2 are respectively feedstock end and chemical fertilizer granule discharge end, are respectively equipped with a frame 5 in the left and right sides of cylinder, are rotatablely equipped with a leading screw 6 between the top of two frames.Frame is welded and fixed by section bar and forms, and acting as of frame supports and install leading screw, any shape and structure and the frame of leading screw can be supported all within the utility model protection domain, and the bottom of frame is connected by foundation bolt and ground.As shown in Figure 4, the outer wall of leading screw is provided with two, and independently the externally threaded rotation direction of external screw thread 61, two can be identical mutually, also can be contrary.The two ends of leading screw and the centre position of leading screw are optical axis.The two ends of leading screw are connected with gantry rotation by bearing, and for driving the rotation of leading screw, one end of leading screw is connected with the motor 12 fixed on the ground by V belt translation 11.Be specially: be fixed with a driven pulley in one end of leading screw, fixedly mount driving pulley being positioned on ground motor output shaft, driving pulley is connected by belt with driven pulley.Certainly, also by gear drive or Worm Wheel System, leading screw and motor output shaft can be linked together.
Because the axial dimension of cylinder is larger, be generally 4 to 8 meters, stablizing for ease of leading screw, prevents amount of deflection in the middle part of leading screw excessive, is provided with a supporting leg 7 at the middle part of cylinder, as shown in Figure 5, supporting leg is section bar weldment, and the top of supporting leg and the middle part of leading screw are rotationally connected, and is provided with a roller 71 in the bottom of supporting leg by axis of rotation, roller coordinates with the contact internal walls of cylinder, and roller plane is parallel with the cross section of cylinder.When the drum turns, roller can be driven to rotate.Roller quality is comparatively large, and under the effect of roller gravity, supporting leg is in vertical position, and roller contacts with inner wall of rotary drum all the time, plays the supporting role to leading screw.
The leading screw at two ends, supporting leg left and right is separately installed with feed screw nut 8, two feed screw nut coordinate with the external screw thread at leading screw two ends respectively.When screw turns, can drive feed screw nut along lead screw shaft to movement.Two external thread rotaries are to time identical, and two feed screw nuts move in the same way; Two external thread rotaries to time contrary, the oppositely movement of two feed screw nuts.Two support bars 9 are respectively equipped with on the top of each feed screw nut, as shown in Figure 5, two support bars become herringbone to arrange, each support bar includes fixed bar 91 and motion bar 92, wherein the outer wall of fixed bar and feed screw nut is welded and fixed, fixed bar is circle or the square metal bar of hollow, in the inner chamber of fixed bar, be equipped with motion bar, and the profile of motion bar and the inner chamber of fixed bar adapt.Fixed bar coordinates a bolt 13 is installed, when bolt screw rod holds out against on motion bar, the locking between fixed bar and motion bar can be realized; Unclamp bolt, the position of adjustable bar in fixed bar.A scraper plate 10 is fixed with at the free end of each motion bar, scraper plate is the metalwork of hexahedron, the installation end of scraper plate and the free end of motion bar are connected, one end relative with the installation end of scraper plate is held for acting on, there is between the effect end of scraper plate and the inwall of cylinder a gap, the existence in this gap can avoid the friction between scraper plate and inner wall of rotary drum, and this gap width is less.Being symmetrical arranged of two support bars on each feed screw nut, can ensure the balance of feed screw nut.
When the drum turns, starter motor makes screw turns simultaneously, and the rotating band of leading screw moves moving horizontally of feed screw nut, and then realizes scraper plate moving horizontally along cylinder axis, and the chemical fertilizer raw material be bonded on inner wall of rotary drum just scrapes by scraper plate.When feed screw nut moves to extreme position position, motor reversely rotates, and makes feed screw nut counter motion.Motor also can intermittent rotary, at set intervals machine operation one-period, and feed screw nut moves once, carries out a doctoring application to the chemical fertilizer raw material on inner wall of rotary drum.
