[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figs. 1-3 A screening mechanism for castor oil raw material production includes a base 1 and a screening component 2. A vibration device 3 and a plurality of guide components 4 circumferentially surrounding the vibration device 3 are provided between the base 1 and the screening component 2.
[0024] The screening assembly 2 includes a storage box 21 and at least one screening element 22 stacked on top of the storage box. The screening element 22 and the storage box 21 are connected and locked together by a positioning assembly 5.
[0025] In this embodiment, the vibration device 3 includes a frame 30 fixedly connected to the upper end of the base 1 and a toothed plate 32 fixedly connected to the lower end face of the storage box 21.
[0026] A motor 31 is fixedly connected to the upper end of the frame 30. A disc 33 is fixedly connected to the shaft end of the motor 31. Several circumferentially distributed protrusions 34 are formed on the upper surface of the disc 33. The protrusions 34 are movably connected to the toothed plate 32. When the motor 31 rotates, it drives the disc 33 and the protrusions 34 to rotate. When the protrusions 34 rotate, they continuously rub against the toothed plate 32 to achieve a vibration effect.
[0027] It should be noted that the guide assembly 4 includes a guide rod 41 fixedly connected to the bottom of the storage box 21 and a sleeve 42 fixed to the upper surface of the base 1.
[0028] The guide rod 41 is movably inserted into the sleeve 42. A contact plate 44 is slidably connected inside the sleeve 42. The contact plate 44 abuts against the guide rod 41. A spring 43 is fixedly connected between the contact plate 44 and the sleeve 42. In this embodiment, there are four guide components 4, which are respectively set at the four corners of the base 1. The sleeve 42 limits the guide rod 41 so that the screening component 2 will not sway left and right during the screening process. The spring 43 abuts against the contact plate 44, and the contact plate 44 abuts against the guide rod 41. Thus, the spring 43 provides a buffering force on the guide rod 41, so that when the protrusion 34 enters the groove from the toothed part of the toothed plate 32, the toothed plate 32 falls quickly, thereby reducing the impact damage to the protrusion 34 and the motor 31 caused by the falling of the screening component 2.
[0029] Furthermore, both the storage box 21 and the screening component 22 have a locking interface 23 at their upper ends, and the screening component 22 has a locking part 24 formed at its lower end, which is movably inserted into the locking interface 23.
[0030] The screening component 22 includes a screening frame 28 and a screen 26 slidably connected within the screening frame 28. A ring protrusion 25 is formed on the lower side of the screening frame 28, and the lower end of the screen 26 abuts against the ring protrusion 25. Positioning beads 27 are provided on both sides of the screening frame 28, and the positioning beads 27 abut against the upper end of the screen 26. The storage box 21 has an angled interior for gathering castor seeds in one place for easy removal. The ring protrusion 25 and the positioning beads 27 limit the screen 26, preventing it from moving up and down during vibration. After vibration, the castor seeds need to be removed. Unscrewing the nut 54 separates the storage box 21 and the screening component 22 for easy removal of the castor seeds. When the screen 26 needs to be replaced, pressing the positioning beads 27 removes the screen 26.
[0031] Based on the above embodiments, the positioning component 5 includes a positioning component 51 fixedly connected to the lower side of the screening component 22 and a fixing component 52 fixedly connected to the upper side of the screening frame 28.
[0032] A bolt 53 is fixedly connected to the lower side of the positioning member 51. The bolt 53 passes through the fixing member 52. A nut 54 is threadedly connected to the lower side of the bolt 53. The storage box 21 and the screening member 22 are positioned by the bolt 53 and the nut 54 to prevent the screening member 22 from separating from the storage box 21 during the screening vibration process.
[0033] Working method: During operation, castor seeds are placed into the screening component 22. The motor 31 is turned on to make the disc 33 and the protrusion 34 rotate. When the protrusion 34 rotates, it continuously collides with the toothed plate 32 to achieve the effect of vibration screening. After screening, the storage box 21 and the screening component 22 can be separated by unscrewing the nut 54. The castor seeds are taken out, and then the positioning ball 27 is pressed to remove the screen 26 for inspection. After inspection, the screen 26 is re-fixed under the positioning ball 27. Then the screening component 22 is reinserted into the storage box 21, and the nut 54 is tightened to start the next screening.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
