Detailed description of the invention
As shown in Figures 3 to 5, the present invention includes frame 5, leading screw 6, supporting leg 7, roller 71, feed screw nut 8, support bar 9 and scraper plate 10, below in conjunction with accompanying drawing, present invention is described.
As shown in Figure 3, the two ends, left and right of cylinder 2 are respectively raw material feed 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 can be welded and fixed and be formed by section bar, and leading screw is supported and installs in acting as of frame, and frame any shape and structure and that can support leading screw is all within protection domain of the present invention, and the bottom of frame is connected by foundation bolt and ground.As shown in Figure 4, independently the externally threaded rotation direction of external screw thread 61, two can be identical mutually on the outer wall of leading screw, to be provided with two, 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 rotationally connected by bearing and frame, and for driving the rotation of leading screw, one end of leading screw is by being connected with the motor 12 fixing on the ground with transmission 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 can leading screw and motor output shaft be linked together by gear drive or Worm Wheel System.
Because the axial dimension of cylinder is larger, be generally 4 to 8 meters, for ease of stablizing of leading screw, prevent that leading screw middle part amount of deflection is excessive, be 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 rotatablely equipped with a roller 71 in the bottom of supporting leg by rotating shaft, roller contacts cooperation with the inwall of cylinder, and the transverse cross-section parallel of roller plane and cylinder.In the time that cylinder rotates, can drive roller to rotate.Roller quality is larger, 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.
On the leading screw at two ends, supporting leg left and right, being separately installed with feed screw nut 8, two feed screw nuts coordinates with the external screw thread at leading screw two ends respectively.In the time that leading screw rotates, can drive feed screw nut along lead screw shaft to movement.Two external thread rotaries are when identical, and two feed screw nuts move in the same way; Two external thread rotaries are when contrary, and two feed screw nuts oppositely move.Be respectively equipped with two support bars 9 on the top of each feed screw nut, as shown in Figure 5, two support bars become herringbone setting, 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, is equipped with motion bar, and the profile of motion bar and the inner chamber of fixed bar adapt.On fixed bar, coordinate a bolt 13 is installed, when bolt screw rod holds out against on motion bar, can realize the locking between fixed bar and motion bar; Unclamp bolt, the position of adjustable bar in fixed bar.Be fixed with a scraper plate 10 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 effect end, between the effect end of scraper plate and the inwall of cylinder, there is a gap, the existence in this gap can be avoided 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.
In the time that cylinder rotates, simultaneously starter motor rotates leading screw, and the rotation of leading screw drives moving horizontally of feed screw nut, and then realizes scraper plate along the moving horizontally of cylinder axis, and scraper plate just scrapes the chemical fertilizer raw material being bonded on inner wall of rotary drum.In the time that feed screw nut moves to extreme position position, motor reverse rotation, makes feed screw nut counter motion.Motor also can intermittent rotary, machine operation one-period at set intervals, and feed screw nut moves once, and the chemical fertilizer raw material on inner wall of rotary drum is once struck off to operation.
