Detailed implementation manners
[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0041] Please refer to Figures 1-8 , the present invention provides a technical solution: a rice lifting device, including an elevator 1, a blanking frame 2 fixedly installed on the surface of the elevator 1, a discharging frame 3 communicated with the top side of the elevator 1, the blanking frame 2 is of a cuboid structure, and further includes: a lifting structure 4 arranged inside the blanking frame 2 for guiding the materials during the blanking process; a screening structure 5 arranged at the end side of the discharging frame 3 for screening some broken rice during the discharging process; a control structure 6 arranged below the screening structure 5 for discharging and processing the accumulated materials after screening. By setting the lifting structure 4, the quality of lifting during rice blanking is improved, and to a certain extent, the lifting efficiency of rice is improved; by setting the screening structure 5, the further screening work of the rice after feeding is facilitated, and the filtering effect during the conveying process of the rice is further improved, meeting the use requirements of the rice; by setting the control structure 6, the flexible opening and closing of the baffle plate 56 can be realized at a low position, thus facilitating the centralized treatment work of the filtered debris, rice grains and impurities.
[0042] Next, the specific settings and functions of its lifting structure 4, screening structure 5 and control structure 6 will be specifically described.
[0043] Such as Figures 1-5As shown, the lifting structure 4 includes a limit rod 407 fixedly connected to the L-shaped structure of the side wall of the feeding frame 2, the side wall of the limit rod 407 is slidably connected to a rectangular frame 401, the lower end of the rectangular frame 401 is fixedly connected to a gauze 42, the lower end of the gauze 42 is fixedly connected to the feeding port of the elevator 1, the side wall of the feeding frame 2 is fixedly installed with a mounting frame 403, the inner wall of the mounting frame 403 is fixedly installed with a motor 404, the output end of the motor 404 is fixedly connected with a screw rod 406, the side wall of the feeding frame 2 is fixedly connected with a mounting plate 405, the screw rod 406 is internally rotatably connected to the mounting plate 405, and the screw rod 406 is internally threadedly connected to the rectangular frame 401. By setting the gauze 42 that can be flexibly lifted into a bucket-shaped structure, under the premise of increasing the storage capacity of the feeding frame 2 for rice materials, it not only does not affect the conventional feeding and guiding work of rice, but also facilitates the preliminary screening of debris in the rice material, thereby improving the lifting quality of rice. A through hole 410 is provided on the lower surface of the feeding frame 2, and a limit pin 408 is fixedly connected to the lower surface of the feeding frame 2, and a baffle 409 is rotatably connected to the side wall of the limit pin 408. The baffle 409 is manually rotated to rotate around the limit pin 408 and escape from the limit state. At this time, the debris is discharged through the through hole 410 on the lower surface of the feeding frame 2. A rubber block 411 is glued to the upper surface of the baffle 409. When the baffle 409 is closed, the rubber block 411 is tightly fitted with the bottom surface of the feeding frame 2 to prevent rice from leaking from the gap during the feeding process and improve the sealing performance.
[0044] like Figures 1-3 and Figure 6 as well as Figure 7 As shown, the screening structure 5 includes a connecting frame 51 connected to the discharging frame 3, a screen 52 is fixedly connected to the lower port of the connecting frame 51, and both sides of the connecting frame 51 are connected and fixedly connected with a through pipe 55 with an opening facing downward. Due to gravity and the inclined surface, the complete rice grains roll into the through pipe 55 along the two sides of the screen 52 and are transported to the finished product warehouse through the through pipe 55. The cross section of the screen 52 is an inverted V shape. The cross section of the screen 52 is an inverted V shape, which can increase the screening area, make the rice slide along the inclined surfaces on both sides, extend the residence time of the material on the screen 52, and improve the screening efficiency. A collecting bucket 53 is fixedly connected between the two through pipes 55, and two connecting pins 54 are fixedly connected to the lower side of the collecting bucket 53. The side walls of the two connecting pins 54 are slidably connected with a baffle 56, and the baffle 56 slides through the collecting bucket 53. Broken particles, broken rice and impurities fall through the mesh of the screen 52 due to their small size and fall into the collecting bucket 53 below for temporary storage.
[0045] like Figures 1-3 and Figures 6-8As shown, the control structure 6 includes a stopper 63 fixedly connected to the end of the connecting pin 54 away from the collecting bucket 53, and a spring 64 is sleeved on the surface of the connecting pin 54. The two ends of the spring 64 are fixedly connected to the stopper 63 and the baffle 56 respectively. The spring 64 generates a reset force due to elastic deformation, pushing the baffle 56 to slide in the opposite direction along the connecting pin 54 until the initial closed state is restored to prevent the unscreened materials from leaking out. The side wall of the collecting bucket 53 is fixedly connected to two connecting bars 62, and the inner rotation of the two connecting bars 62 is connected to a rotating pin 65. The side wall of the rotating pin 65 is fixedly connected to a pulley 66. The surface of the baffle 56 is fixedly connected to a pull rope 61, and the pull rope 61 is located on the side wall of the pulley 66. The pull rope 61 is driven to move downward, and the pull rope 61 slides on the surface of the pulley 66, which has the effect of changing the direction of the pulling force of the pull rope 61. The lower end of the pull rope 61 is fixedly connected to a ball. Manually pull the ball to drive the pull rope 61 to move downward.
[0046] Working principle: When rice enters the feeding frame 2 from the outside, the motor 404 is started, and its output end drives the screw rod 406 to rotate. Since the screw rod 406 is threadedly connected to the rectangular frame 401, and the rectangular frame 401 is slidably connected to the feeding frame 2 through the limit rod 407, the rectangular frame 401 will reciprocate up and down along the limit rod 407, and the gauze 42 at the lower end of the rectangular frame 401 moves synchronously with the rectangular frame 401, stirring and guiding the falling rice, avoiding accumulation of materials at the feed inlet, and ensuring uniform entry into the elevator 1. The mesh design of the gauze 42 can filter out debris and impurities. When debris accumulates at the bottom of the feeding frame 2, the baffle 409 is manually rotated to make it rotate around the limit pin 408 rotates and leaves the limited state. At this time, the debris is discharged through the through hole 410 on the lower surface of the feeding frame 2. When the blocking piece 409 is closed, the rubber block 411 fits tightly with the bottom surface of the feeding frame 2 to prevent the rice from leaking out from the gap during the feeding process, thereby improving the sealing performance. By setting the gauze mesh 42 that can be flexibly lifted into a bucket-shaped structure, while increasing the feeding frame 2 to store rice materials, it not only does not affect the conventional feeding and guiding work of the rice, but also facilitates the preliminary screening of the debris in the rice material, thereby improving the lifting quality of the rice. By setting the lifting structure 4, the quality of lifting the rice during feeding is improved, thereby improving the lifting efficiency of the rice to a certain extent.
[0047] The rice transported by the elevator falls from the discharge frame 3 into the connecting frame 51 and falls on the screen 52. The cross section of the screen 52 is an inverted V-shape, which has the following functions: increasing the screening area, making the rice slide along the inclined surfaces on both sides, prolonging the residence time of the material on the screen 52, and improving the screening efficiency; due to the gravity and the inclined surface, the complete rice particles roll into the through pipe 55 along both sides of the screen 52, and are transported to the finished product warehouse through the through pipe 55; the broken particles, broken rice and impurities fall through the mesh of the screen 52 due to their small size, and fall into the collecting bucket 53 below for temporary storage. The elevator 1 is moved to a suitable position, and the baffle 56 is pulled out to realize the centralized processing of a certain amount of debris collected. By setting the screening structure 5, it is convenient to further screen the rice after feeding, further improve the filtering effect during the transportation of the rice, and meet the use requirements of the rice.
[0048] When the crushed particles in the collecting bucket 53 accumulate to a certain weight, the ball is manually pulled to drive the pull rope 61 to move downward. The pull rope 61 slides on the surface of the pulley 66, which has the effect of changing the direction of the pulling force of the pull rope 61, thereby facilitating the pulling of the baffle 56. At this time, the discharge port can be opened, and the impurities are discharged to the specified position through the discharge port. After the ball is released, the spring 64 generates a reset force due to elastic deformation, pushing the baffle 56 to slide in the opposite direction along the connecting pin 54 until the initial closed state is restored to prevent the unscreened material from leaking out. The block 63 is fixed at the end of the connecting pin 54 to limit the sliding stroke of the baffle 56 and avoid excessive stretching or compression of the spring 64. By setting the control structure 6, the baffle 56 can be flexibly switched on and off at a low position, thereby facilitating the centralized processing of the filtered debris and impurities.
