During the seed processing, some dust particles and broken residues need to be screened by a special dust removal device to improve the quality of the seeds.
[0003] There are still some problems in the existing seed screening and dust removal devices. First of all, the existing ones mainly inject seeds directly through the feeding port and screen them through a filter screen. This method is relatively single, prone to seed accumulation on the filter screen, making it difficult to comprehensively remove dust, and the feeding method is also inconvenient. Secondly, it is inevitable that dust particles will float around during dust removal. Some of the existing ones use special dust suction equipment for smoke and dust removal, with a relatively high overall cost and low use effect. Content of the Utility Model

Detailed implementation manners
[0027] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in combination with the specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.
[0028] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.
[0029] The following describes a dust removal device for seed screening provided by some embodiments of the present utility model with reference to the accompanying drawings.
[0030] Embodiment 1:
[0031] Combined with Figures 1 - 3 as shown, a dust removal device for seed screening provided by the present utility model
[0032] Specifically, it includes a machine body 1. A screw feeding channel 3 is installed through the left top of the machine body 1. At the bottom of the screw feeding channel 3 on the left side of the machine body 1, a mounting base 4 is installed. On one side of the connection between the screw feeding channel 3 and the mounting base 4, a filter screen 18 is embedded and installed. In the middle of the interior of the machine body 1, an arc-shaped sieve plate 14 is provided. At the bottom of the left and right sides of the arc-shaped sieve plate 14, two groups of rotating kits 20 are symmetrically connected. On the left and right sides of the interior of the machine body 1, mounting brackets 21 rotatably connected to the two groups of rotating kits 20 are symmetrically installed. At the right bottom of the outside of the machine body 1, an installation box 11 is provided. At the inner bottom of the installation box 11, a spring 15 is installed. At the top of the spring 15, a connecting slide plate 16 is installed. At the top of the connecting slide plate 16, a lifting rack 7 is connected. Through the left fixed end of the screw feeding channel 3, a feeding through pipe 5 is installed. At the right low end of the screw feeding channel 3, directly above the arc-shaped sieve plate 14, a discharging funnel 6 is installed. At the front end of the connecting slide plate 16 outside the installation box 11, a pressing plate 12 is connected. At the front end of the spring 15 on the outer side of the installation box 11, a sliding hole 13 is opened. The sliding hole 13 is mainly used to limit the movement of the connecting slide plate 16. The pressing plate 12 can be slidably clamped inside the sliding hole 13. Inside the mounting base 4, a pull-out dust collection box 19 is slidably embedded left and right. The pull-out dust collection box 19 can take out the collected dust to the outside for unified cleaning. At the front end of the arc-shaped sieve plate 14 outside the machine body 1, a sealing cover 8 is installed. The sealing cover 8 is mainly used to seal the machine body 1 and is also convenient for taking out the screened seeds from the arc-shaped sieve plate 14 after opening. With the use of the above components, the seeds are first conveyed through the screw feeding channel 3. After some dust and impurities are separated by screening through the filter screen 18, the seeds continue to pass through the discharging funnel 6 and fall on the arc-shaped sieve plate 14. Due to the impact force and the elastic effect of the spring 15 in the installation box 11, through the operation of each component, the arc-shaped sieve plate 14 continuously swings horizontally in a cycle, further screening the seeds, improving the comprehensiveness and diversity of dust removal and screening, and enhancing the use convenience.
[0033] Embodiment 2:
[0034] Combined with Figure 1 and Figure 2 shown, on the basis of Embodiment 1,
[0035] Specifically, a water tank 17 is slidably embedded at the bottom of the inner part of the machine body 1 at the bottom end of the arc-shaped sieve leakage plate 14. Water can be added to the water tank 17 to directly collect the falling dust, preventing the dust from spreading further and affecting the screening and dust removal effect. At the same time, it is taken out of the outside through the pull-out plate 9 for unified cleaning. The front end of the water tank 17 is connected to the pull-out plate 9 on the outside of the machine body 1. The use of the above-mentioned components, including the components in the first embodiment, enables the dust removal of seeds to be mainly carried out through the filter screen 18 in the screw feeding channel 3 and the arc-shaped sieve leakage plate 14 inside the machine body 1, with relatively high airtightness. After precipitation and collection by the water tank 17, it prevents the dust from overflowing, reduces costs, and improves the use effect.
[0036] Combined Figure 1 with Figure 2 as shown, in the above embodiment,
[0037] Specifically, a support frame 2 is installed at the bottom of the machine body 1. The support frame 2 mainly supports and stabilizes the machine body 1, and at the same time facilitates the installation and fixation of the installation box 11. The installation box 11 is installed at the left top end of the support frame 2.
[0038] The working principle and usage process of the present utility model: First, when in use, seeds are injected into the screw feeding channel 3 through the feeding through pipe 5 by an external feeding pipe. Through the operation of the driving mechanism, the internal feeding screw conveys the seeds into the machine body 1 through the discharging funnel 6. During the conveying process of the seeds in the screw feeding channel 3, some dust and impurities are sieved through the filter screen 18 into the pull-out dust collection box 19 inside the installation base 4, and the seeds directly fall on the arc-shaped sieve leakage plate 14 through the impact force of the discharging funnel 6 and the elastic action of the spring 15 in the installation box 11. Through the pressing plate 12 along the sliding hole 13, the connecting sliding plate 16 squeezes the spring 15, driving the lifting rack 7 to mesh and drive with the transmission gear shaft 10, and making the rotating kit 20 rotate along the installation bracket 21, driving the arc-shaped sieve leakage plate 14 to swing horizontally to further sieve the seeds, so as to improve the comprehensiveness and diversity of dust removal and screening, and at the same time improve the usage convenience. Secondly, when in use, the use of the above-mentioned components enables the dust removal of seeds to be mainly carried out through the filter screen 18 in the screw feeding channel 3 and the arc-shaped sieve leakage plate 14 inside the machine body 1 for screening and dust removal respectively. The airtightness of the two dust removals is relatively high, and most of the dust mainly falls into the water tank 17 at the bottom of the machine body 1 for collection, preventing the dust from overflowing, with relatively low overall usage cost and improved usage effect.
[0039] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
