Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0022] like Figure 1-4 As shown, this utility model provides a Z-shaped feeding device, including a base 1, a column 2 fixedly connected to the base 1, a vertical groove 14 formed in the column 2, a first lead screw 4 and a guide rod 13 disposed in the groove 14, a motor for driving the first lead screw 4 to rotate disposed at the bottom of the groove 14, and a lifting platform 3 disposed on the first lead screw 4 and the guide rod 13. A raising seat 28 is fixedly connected to the lifting platform 3, a second lead screw 12 disposed in the raising seat 28, and a first motor 8 for driving the second lead screw 12 to rotate disposed on the raising seat 28. A first slider 5 is disposed on the second lead screw 12, and a collecting hopper 6 is fixedly connected to the top of the first slider 5. A door 7 is formed on one side of the collecting hopper 6, a door hinge is disposed on the top edge of the door 7, and an extension 29 longer than the bottom wall of the collecting hopper 6 is disposed on the bottom edge. A second motor 10 is installed on the bottom wall of the hopper 6. The second motor 10 is a servo motor, and a push rod 9 is fixedly connected to the output shaft. The other end of the push rod 9 is fixedly connected to the extension 29 of the hopper door 7.
[0023] like Figure 1 As shown, a screening hopper 15 is fixedly connected to the top of the column 2 on the opposite side of the lifting platform 3, and a discharge port 24 is provided at the bottom of the screening hopper 15. The height of the riser 28 must be greater than the thickness of the bottom wall of the groove 14 to ensure that when the lifting platform 3 is raised to its highest point, the collecting hopper 6 will not be blocked by the top wall of the column 2 when it moves toward the screening hopper 15; the moving distance of the collecting hopper 6 must be greater than the width of the column 2 to ensure that after the collecting hopper 6 has moved toward the screening hopper 15, the material inside can fall into the screening hopper 15 when the hopper door 7 is opened, and flow out from the discharge port 24 after screening. The inner bottom wall of the collecting hopper 6 is a slope with a thickness that gradually decreases toward the hopper door 7, so that the material can slide out due to its own weight after the hopper door 7 is opened.
[0024] In use, the material is poured into the collecting hopper 6, and the first screw 4 drives the lifting platform 3 to move upward until the lifting platform 3 reaches its highest point; then the first motor 8 drives the second screw 12 to rotate, so that the collecting hopper 6 moves closer to the screening hopper 15 until the hopper door 7 is above the screening hopper 15; then the second motor 10 drives the push rod 9 to extend, and the hopper door 7 opens around the door hinge, allowing the material to fall into the screening hopper 15 for screening.
[0025] like Figure 5 As shown, a movable groove 17 is provided inside the screening hopper 15, and a screen 16 is provided inside the movable groove 17. A first swing rod 18 and a second swing rod 19 are fixedly connected to both ends of the screen 16, respectively. The inner diameter of the movable groove 17 is larger than that of the screening hopper 15 to ensure that the screen 16 has space to swing within the screening hopper 15. A drive platform 30 is fixedly connected to one side of the screening hopper 15, and a third motor 20 is fixedly connected to the drive platform 30. An inclined disc 21 is fixedly connected to the output shaft of the third motor 20. The vertical cross-section of the inclined disc 21 is trapezoidal and abuts against the first swing rod 18 on one side. The end face of the first swing rod 18 is hemispherical. Springs 22 are fitted on both the first swing rod 18 and the second swing rod 19. A limiting disc 23 with a diameter larger than that of the spring 22 is provided on the end face of the second swing rod 19 to prevent the spring 22 from falling off.
[0026] During screening, the third motor 20 drives the inclined disc 21 to rotate, and the inclined disc 21 generates a distance difference in the horizontal direction. Because the first swing rod 18 is always in contact with the inclined disc 21 under the action of the spring 22, it pushes the swing rod to generate displacement in the horizontal direction, causing the screen 16 to move left and right to screen the material.
[0027] like Figure 1 As shown, a mixing hopper 25 can also be installed below the discharge port 24. An auger is installed inside the mixing hopper 25 to mix various materials. The mixing hopper 25 is placed on the base 1 via support columns 27, and a discharge port 26 is provided below it. Figure 3 As shown, the two sides of the door 7 are also provided with outwardly extending flanges 11 to enhance the sealing performance of the door 7.
