[0032] Reference Figure 4 and Figure 5As shown, in this embodiment: the collecting device 4 includes two fixing frames 401, the two fixing frames 401 are fixedly connected to the discharge plate 6, the surfaces of the two fixing frames 401 are fixedly connected with a ring 402, the surface of the bracket 2 is fixedly connected with two fixing plates 403, the surfaces of the two fixing plates 403 are fixedly connected with a placement plate 404, the upper surface of the placement plate 404 is fixedly connected with two limiting plates 405, the upper surface of the placement plate 404 is slidably connected with a waste collection box 406, the waste collection box 406 is against the surface of the limiting plate 405, by setting the collecting device 4, using the fixing frames 40 1. The cooperation among the ring 402, the fixed plate 403, the placement plate 404, the limit plate 405 and the waste collection box 406 can realize the convenient and rapid bagging of the selected rice without the need for workers to manually receive the materials, which effectively reduces the labor intensity of the workers. At the same time, it can reduce the stagnation time of the screening machine and improve the working efficiency of the screening machine. The lower surface of the placement plate 404 is fixedly connected with an L plate 409, and the short arm of the L plate 409 is fixedly connected with a telescopic rod 410. The other end of the telescopic rod 410 is fixedly connected with a limit block 411, and the limit block 411 slides with the placement plate 404 The arc surface of the telescopic rod 410 is sleeved with a spring 412, and the two ends of the spring 412 are fixedly connected to the limit block 411 and the L plate 409 respectively. The limit block 411 limits the position of the waste collection box to avoid the displacement of the waste collection box caused by the vibration of the screening machine. The spring 412, the telescopic rod 410 and the limit block 411 can automatically fix the waste collection box. The telescopic rod 410 can prevent the spring 412 from bending during the compression process. The arc surface of the ring 402 is fixedly connected with a plurality of sharp cones 408. The folded edge of the plastic bag opening is pressed toward the side with the sharp cone 408, and the sharp cone 408 will penetrate the plastic bag, and the circular ring 402 can open the plastic bag opening. The sharp cone 408 can fix the position of the plastic bag to prevent the plastic bag from losing contact with the circular ring 402 and causing the rice to spill. The surfaces of the two fixing plates 403 are rotatably connected to a plurality of rollers 407. When the plastic bag filled with rice is pulled, the plastic bag will drive the rollers 407 to rotate. The rollers 407 can facilitate the removal of the plastic bag and prevent the plastic bag from being worn or damaged due to direct contact with the ground.
[0033] Reference Figure 2 and Figure 3As shown, specifically, the blocking device 5 includes a fixing bar 51, the fixing bar 51 is fixedly connected to the discharge plate 6, the surface of the discharge plate 6 is slidably connected with a baffle 52, the surface of the baffle 52 is fixedly connected with a handle 53, the surface of the fixing bar 51 slides through a limiting rod 56, a limiting hole 54 is provided on the surface of the baffle 52, and the limiting rod 56 is slidably connected to the inner wall of the limiting hole 54. By setting the blocking device 5, the selected rice can be effectively prevented from continuing to flow, and the situation that the rice continues to flow to the discharge plate 6 when the workers put on the plastic bag and causes the rice to spill can be avoided, thereby reducing the waste of rice. The blocking device 5 can reduce the downtime of the screening machine and improve the working efficiency of the screening machine. The arc surface of 56 is sleeved with a tension spring 55, and the two ends of the tension spring 55 are fixedly connected to the limit rod 56 and the fixing strip 51 respectively. When the limit rod 56 is loosened, the tension spring 55 drives the ball 57 to press against the surface of the baffle 52. When the block presses against the surface of the discharge plate 6, the ball 57 contacts the limit hole 54. At this time, the tension spring 55 begins to drive the limit rod 56 to insert into the limit hole 54 with the help of its own elastic force, so that the position of the block can be fixed. The tension spring 55 can achieve the effect of automatically resetting the limit rod 56. One end of the limit rod 56 is rotatably connected with the ball 57. The ball 57 facilitates the insertion of the limit rod 56 into the limit hole 54, thereby reducing the friction between the limit rod 56 and the baffle 52.
[0034] Working principle: when the screening machine is needed to screen the rice, the screening machine is first started, and then the rice is poured onto the screen 3 on the inner wall of the box. At this time, due to the vibration of the screening machine, the selected rice will flow along the screen 3 to the direction of the discharge plate 6, and the inferior rice will flow along the box to the direction close to the waste outlet box 7. When using the screening machine, the selected rice needs to be put into a plastic bag. The worker first puts the plastic bag on the surface of the ring 402, and then presses the folded edge of the plastic bag mouth to the side with the sharp cone 408. The sharp cone 408 will penetrate the plastic bag, and the ring 40 2 can open the mouth of the plastic bag, and the sharp cone 408 can fix the position of the plastic bag to prevent the plastic bag from being out of contact with the ring 402 and causing the rice to spill. After the plastic bag is filled with selected rice, the folded edge of the plastic bag mouth is out of contact with the sharp cone 408 to complete the bagging and packaging of the rice. The surface of the bracket 2 is provided with a roller 407. When the plastic bag filled with rice is pulled, the plastic bag will drive the roller 407 to rotate. The roller 407 can facilitate the removal of the plastic bag, and prevent the plastic bag from being directly pulled on the ground and causing the plastic bag to be worn and damaged. The bad situation occurs. At the same time, when the screening machine is used, the inferior rice will fall into the waste collection box with the help of the waste outlet box 7. When it is necessary to take out the waste collection box, the waste collection box is pulled, and the waste collection box slides along the surface of the placement plate 404. The waste collection box will squeeze the limit block 411, and the limit block 411 will compress the telescopic rod 410 and the spring 412. The limit block 411 can limit the position of the waste collection box to avoid the displacement of the waste collection box caused by the vibration of the screening machine. The spring 412, the telescopic rod 410 and the limit block 411 can realize the function of automatically fixing the waste collection box, and the telescopic rod 410 can prevent the spring 412 from bending during the compression process. By setting the collecting device 4, utilizing the mutual cooperation among the fixing frame 401, the ring 402, the fixing plate 403, the placing plate 404, the limiting plate 405 and the waste collection box 406, the selected rice can be conveniently and quickly bagged and packaged without the need for workers to manually receive the materials, thus effectively reducing the labor intensity of the workers. At the same time, it can reduce the stagnation time of the screening machine and improve the working efficiency of the screening machine.
[0035] After the selected rice is packed in bags, the empty plastic bag needs to be put on the ring 402. At this time, the blocking device 5 can be used to block the rice. First, the limit rod 56 is pulled, and the limit rod 56 slides along the surface of the fixing strip 51. The limit rod 56 will squeeze the tension spring 55, so that the limit rod 56 is out of contact with the baffle 52. At this time, the block slides along the surface of the discharge plate 6 with the help of its own gravity. At this time, the limit rod 56 can be loosened, and the tension spring 55 drives the ball 57 to abut against the surface of the baffle 52. When the block abuts against the surface of the discharge plate 6, the ball 57 contacts the limit hole 54. At this time, the tension spring 55 begins to use its own elastic force to The force drives the limit rod 56 to be inserted into the limit hole 54, so that the position of the block can be fixed, and the tension spring 55 can achieve the function of automatically resetting the limit rod 56, and the ball 57 can facilitate the limit rod 56 to be inserted into the limit hole 54, so as to reduce the friction between the limit rod 56 and the baffle 52. By setting the blocking device 5, the selected rice can be effectively prevented from continuing to flow, and the rice can be prevented from continuing to flow to the discharge plate 6 when the workers put on the plastic bag, resulting in the rice spilling, thereby reducing the waste of rice. The blocking device 5 can reduce the downtime of the screening machine and improve the working efficiency of the screening machine.
