Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wheat seed screening, and particularly relates to a wheat seed screening device. Background Art
[0002] In the process of agricultural production and planting, mechanical production of agricultural production is realized through automated machinery to increase production efficiency and save labor input. In the process of agricultural production, after the harvester collects the harvested crop seeds such as wheat seeds, the seeds need to be screened.
[0003] By screening the seeds, the plump seeds can be screened out, and for the small-grained wheat, as well as the grass seeds, weeds, and wheat stem and leaf impurities mixed in the wheat, they need to be removed during the screening process. Obtaining wheat seeds with plump particle sizes can not only be processed into high-quality wheat by-products, but also, the plump-seeded seeds can be used as wheat seeds.
[0004] At present, the sorting of wheat uses a vibrating screen for sieving. During the sieving process, small-grained grass seeds, wheat seeds (shriveled seeds), as well as soil, stones, etc. are removed. The plump and large-grained wheat seeds are retained. However, in the actual sorting process, the impurities of different grades of wheat are different. For wheat with poor quality, there are a large number of impurities such as weeds, plant straws, and stones. During the sorting process, impurities such as weeds, plant straws, and stones cannot be sieved out and often follow the large-grained seeds to fall from the vibrating screen and are mixed in the sieve.
[0005] Therefore, it is necessary to replace the sieve with a larger sieve hole type to continue sieving. However, after sieving, there are still impurities in the wheat seeds.
[0006] Therefore, obviously, the above method not only leads to excessive sieving times and cumbersome steps, but also makes the sorting of wheat extremely complex and difficult. Content of the Utility Model
[0007] Based on the above background, the purpose of the utility model is to provide a wheat seed screening device.
[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0013] The material blocking component further includes a material blocking plate fixedly installed at the bottom of the cross beam.

[0030] 1. During the working process, turn the pressing nut downward, and the pressing nut drives the connecting seat - crossbeam structure to slide down until the comb - tooth structure directly contacts the secondary sieve mesh. During the vibrating sieving process, since the secondary sieve mesh vibrates continuously, during this process, the connecting seat - crossbeam slides relative to the inner sliding rod continuously. During this process, telescopic movement buffering is formed through the spring (forming buffering through the elastic deformation of the spring is a conventional application of the inherent property of the spring), so as to avoid the secondary sieve mesh hitting the comb - tooth structure too hard, and avoid the deformation of the comb - tooth structure and the damage of the sieve mesh.
[0031] During this process, weeds, wheat stems and leaves in the wheat are intercepted in the comb - tooth structure, and in this way, impurities such as slightly longer grass and stems in the wheat are removed.
[0032] 2. Through the adjustable angle setting of the baffle plate, flipping the baffle plate can change the distance between the baffle plate and the secondary sieve mesh, so as to adjust the distance according to the impurities in the wheat. For example, when the impurity particle size is large, reduce the distance, and by delaying the feeding speed of the wheat, impurities such as stones are intercepted. During sieving, the operator continuously removes the intercepted stone impurities.
[0033] 3. Through the upper primary sieve assembly and the lower vibrating sieve, two - stage sieving is realized, so as to fully remove the impurities in the wheat. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Embodiment 1
[0045] As Figures 1-5 shown, a wheat seed screening device includes a vibration screening mechanism, and the vibration screening mechanism includes a lower vibration sieve assembly and an upper primary sieve assembly 1 fixedly installed at the top position of the lower vibration sieve assembly.
[0046] Specifically, the above-mentioned lower vibration sieve assembly includes a sieve frame 2 (a guide plate is fixedly installed at the discharge end of the sieve frame 2), and a secondary sieve mesh 21 is fixedly connected to the bottom of the sieve frame 2.
[0047] A number of material combing components 3 are fixedly connected inside the sieve frame 2, and a material blocking component is fixedly connected at the discharge end position of the sieve frame 2; both the material combing component 3 and the material blocking component include a cross beam 32 that can elastically lift and lower. The material combing component 3 further includes a comb plate 33 fixedly installed at the bottom position of the cross beam 32, and a number of comb tooth structures 331 (the comb tooth structures 331 are rectangular structures) are provided on the comb plate 33.
[0048] Specifically, a number of sliding openings are respectively provided on the front and rear side walls of the sieve frame 2, an inner sliding rod 31 is fixedly connected inside the sliding openings, a connecting seat 321 (the shape of the connecting seat 321 is L-shaped) is slidably connected to the inner sliding rod 31, a screw rod is fixedly connected to the connecting seat 321, and the screw rod is threadedly connected to the cross beam 32.
[0049] At the same time, a spring 34 is sleeved on the inner sliding rod 31, and both ends of the spring 34 are respectively fixedly connected to the connecting seat 321 and the sliding opening; the upper end of the inner sliding rod 31 is threadedly connected with a pressing nut.
[0050] During the working process, the pressing nut is turned downward, and the pressing nut drives the connecting seat 321 - cross beam 32 structure to slide downward until the comb tooth structure 331 directly abuts against the secondary sieve mesh 21. During the vibrating sieving process, since the secondary sieve mesh 21 vibrates continuously, in this process, the connecting seat 321 - cross beam 32 continuously slides relative to the inner sliding rod 31. In this process, a telescopic movement buffer is formed through the spring 34 (forming a buffer through the elastic deformation of the spring 34 is a conventional application of the inherent property of the spring), so as to avoid the secondary sieve mesh 21 hitting the comb tooth structure 331 too hard, and to avoid the deformation of the comb tooth structure 331 and the damage of the sieve mesh.
[0051] During this process, weeds, wheat stems and leaves in the wheat are intercepted in the comb tooth structure 331, and in this way, impurities such as weeds and stems with slightly larger lengths in the wheat are removed.
[0052] Similarly, the above-mentioned comb plate 33 is slidably assembled on the cross beam 32 through a number of buffer connecting pieces. Specifically, the buffer connecting piece includes a sliding rod 331 fixedly connected to the top position of the comb plate 33, and the sliding rod 331 is slidably connected to the cross beam 32;
[0053] A buffer spring 3311 is sleeved on the sliding rod 331, and both ends of the buffer spring 3311 are respectively fixedly connected to the top of the comb plate 33 and the bottom of the cross beam 32.
[0054] Similarly, further buffer protection is achieved through the buffer spring 3311 to prevent the deformation of the comb tooth structure 331 and the damage of the sieve mesh.
[0055] Embodiment 2
[0056] Such as Figures 1-5As shown in the figure, on the basis of the structure of Embodiment 1, the above-mentioned material baffle component further includes a baffle plate 5 fixedly installed at the bottom of the cross beam 32; the angle of the baffle plate 5 is adjustable (specifically, since a screw rod is fixedly connected to the connecting seat 321, the screw rod is threadedly connected to the cross beam 32, and a threaded groove is opened in the cross beam 32), and by flipping the baffle plate 5, the distance between the baffle plate 5 and the secondary screen 21 is changed, so as to adjust the distance according to the impurities in the wheat. For example, when the particle size of the impurities is large, the distance is reduced, and by delaying the feeding speed of the wheat, impurities such as stones are intercepted. During sieving, the operator continuously removes the intercepted stones and impurities.
[0057] Embodiment 3
[0058] Such as Figures 1-5 As shown in the figure, on the basis of the structure of Embodiment 2, the same as the existing vibrating screen, the above-mentioned lower vibrating screen assembly further includes a vibrating main beam 6 fixedly connected to the bottom of the screen frame 2; a vibrating motor 61 is fixedly installed on the vibrating main beam 6. Specifically, mounting seats for installing the vibrating main beam 6 are respectively fixedly connected to the front and rear sides of the screen frame 2. The same as the vibrating sieving of the existing vibrating screen, when the vibrating motor 61 works, the entire screen frame 2 vibrates to realize sieving the material.
[0059] At the same time, the structure is the same as that of the existing vibrating screen. A support frame is fixedly connected to the bottom of the above-mentioned screen frame 2, and a plurality of spring members are fixedly connected between the bottom of the screen frame 2 and the support; the spring members include reinforcing springs, and limiting columns sleeved in the reinforcing springs are respectively fixedly connected to the bottom of the screen frame 2 and the top of the support.
[0060] Embodiment 4
[0061] Such as Figures 1-5 As shown in the figure, on the basis of the structure of Embodiment 3, the upper primary sieve assembly 1 includes an upper screen frame fixedly connected to the top of the screen frame 2. The upper screen frame includes a U-shaped base 13, an upper screen frame 11 is fixedly connected to the top of the U-shaped base 13, and a plurality of sieve rods 12 are fixedly connected inside the U-shaped base 13; the gap between the sieve rods is larger than the mesh size of the secondary screen 21. During the sieving process, the wheat is preliminarily sieved.
[0062] Specifically, a pair of U-shaped connecting plates 14 are respectively fixedly installed on both sides of the top of the U-shaped base 13, and the U-shaped connecting plates 13 are fixedly installed at the top of the screen frame 2.
[0063] During the vibrating sieving process, the wheat passes through between the sieve rods. Large-sized impurities such as weeds and stones are intercepted.
