Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural product processing equipment, in particular to seed impurity removal and screening equipment. Background Art
[0002] Seed impurity removal and screening equipment is an important link in ensuring seed quality and improving crop yield and quality in modern agricultural production. It is crucial for seed processing, seed scientific research and seed commercial production.
[0003] Although today's technology has many advantages, its disadvantage is that during the seed formation process, genetic factors may cause abnormal expression of certain genes, resulting in uneven seed size. Large seeds generally have a longer growth cycle and need to grow slowly and patiently in a suitable growth environment. Small seeds have a relatively short growth cycle and grow quickly. However, some of today's seed impurity removal and screening equipment only screens impurities, and seeds of different sizes cannot have their own characteristics and exert their greater growth advantages. At the same time, in terms of feeding, feeding too much at one time may cause the power source to overload, seriously endangering the stable operation of the system and reducing the service life of the equipment.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-5 The utility model provides a technical solution: a seed impurity removal and screening device, comprising: a base plate 1, a plurality of flexible plates 2 are arranged on the top of the base plate 1 by bolts, a support frame 3 is arranged on the outer surface of the plurality of flexible plates 2 by bolts, a step plate 4 is fixedly connected to the top of the support frame 3, a plurality of filtering holes 5 are provided on the outer surface of the step plate 4, a motor 6 is fixedly connected to the top of the base plate 1, a rotating shaft 7 is arranged on the motor 6 through the output shaft, a cam 8 is fixedly installed on the outer surface of the rotating shaft 7, a plurality of connecting plates 9 are fixedly connected to the outer surface of the base plate 1, a plurality of collecting boxes 10 are fixedly connected to the outer surface of the collecting box 10, a plurality of discharge pipes 11 are fixedly connected to the outer surface of the collecting box 10, a plurality of partition plates 12 are fixedly connected to the inner surface of the collecting box 10, and two slide grooves 16 are provided on the top of the step plate 4, so as to avoid the problem of reduced germination rate of seeds due to the mismatch of growth environment.
[0023] like Figure 1-5 As shown, the outer surface of the collecting box 10 is provided with a plurality of fixing plates 13 by bolts, the plurality of fixing plates 13 are provided with a feed box 14 by bolts, the bottom of the feed box 14 is fixedly connected with a plurality of sliding blocks 15, the outer surface of the feed box 14 is fixedly connected with a support plate 17, the top of the support plate 17 is fixedly connected with a motor 18, the motor 18 is provided with a rotating shaft 19 through an output shaft, and a rotating block 20 is fixedly installed on one side of the rotating shaft 19 close to the inside of the feed box 14, so as to avoid excessive feeding at one time and causing overload of the power source, thereby ensuring the stable operation of the system and improving the service life of the equipment.
[0024] like Figure 1-5 As shown, the second rotating shaft 19 is movably embedded in the inner surface of the feed box 14, and the second rotating shaft 19 can transmit the power of the second motor 18 to the rotating block 20 to make the rotating block 20 rotate.
[0025] like Figure 1-5 As shown, a plurality of sliders 15 are movably embedded in the inner surfaces of the two slide grooves 16 . The cooperation between the slide grooves 16 and the sliders 15 can prevent the feed box 14 from moving along with the movement of the step plate 4 , thereby providing a good working environment for the feed box 14 .
[0026] Working principle: This equipment is a seed impurity removal and screening equipment. When in use, the product to be screened is introduced into the feed box 14, and then the motor 2 18 on the support plate 17 is started. The motor 2 18 drives the rotating shaft 2 19 to rotate through the output shaft, and the rotating shaft 2 19 drives the rotating block 20 to rotate. A plurality of partitions are fixedly connected to the rotating block 20. The plurality of partitions can divide the feed box 14 into several parts with equal volume, and the volume divided by the partitions is at most the rated capacity of the equipment, which avoids excessive feeding at one time. When the material enters the step plate 4, the motor 1 6 on the base plate 1 is started, and the motor 1 6 drives the rotating shaft 1 7 to rotate through the output shaft, and the rotating shaft 1 7 drives the cam 8 to rotate. The cam 8 will squeeze the support frame 3 to displace the support frame 3, and the support frame 3 will drive the step plate 4 to move. The support frame 3 causes the plurality of flexible plates 2 to deform, and the plurality of flexible plates 2 obtain elastic potential energy. When the cam 8 no longer squeezes the support frame 3, the plurality of flexible plates 2 will release The elastic potential energy is released, so that the support frame 3 moves to the initial position, and then the step plate 4 also moves to the initial position, realizing the shaking of the step plate 4, and then the material enters the collection box 10 through the multiple filter holes 5. Because the opening of the filter hole 5 is gradually increased, the smaller material will pass through the filter hole 5 first, and the larger material will gradually move down, and then enter the collection box 10 through the larger filter hole 5 below. The partition plate 12 divides the collection box 10 into several parts, so that products of different sizes can be classified. The partition plate 12 is elastic and will move with the movement of the step plate 4. The material entering the collection box 10 will be discharged from different discharge pipes 11 in turn. The fixed plate 13 on the collection box 10 can provide support for the feed box 14, and the connecting plate 9 can provide support for the collection box 10 to achieve the separation of materials of different sizes. The cooperation of the slider 15 and the slide groove 16 can prevent the feed box 14 from moving with the movement of the step plate 4.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
