[0002] Seed screening technology is a technology used to separate and screen seeds. Seed screening technology is commonly used in the agricultural field to help farmers and growers screen out high-quality seeds to improve crop yield and quality. Seed screening technology generally sorts seeds based on their size, shape, weight and other characteristics to ensure seed quality and consistency. Common seed screening technologies include airflow screening, vibration screening, rotary screening, etc.
[0003] Among them, for vibration screening, in the prior art, when using a sieve plate to screen seeds, inferior small-particle seeds will be discharged through the holes of the sieve plate, and high-quality large-particle seeds will remain on the surface of the sieve plate. When the screening is completed, the staff needs to take out the high-quality large-particle seeds and then screen the next batch of seeds. The overall screening continuity is poor, which affects the overall screening efficiency. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a rapeseed seed screening device to solve the technical problem in the prior art that after the screening is completed, the staff needs to take out the high-quality large-particle seeds and then screen the next batch of seeds, and the overall screening continuity is poor, affecting the overall screening efficiency.

Since the discharge inclined plate is inclined, the high-quality rapeseed seeds are discharged to the outside through the discharge pipe. As can be seen from the above, after the utility model screens the rapeseed seeds, there is no need to take out the high-quality seeds separately, the overall operation is relatively simple, and the overall rapeseed seed screening continuity is good, which greatly improves the screening efficiency of the rapeseed seeds.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0020] The following describes an embodiment of the utility model based on its overall structure.
[0021] A rapeseed seed screening device, such as Figure 1-4 As shown, it includes a main body 1, a sieve plate 3 is movably connected inside the main body 1, and a plurality of sieve holes 4 are opened inside the sieve plate 3, wherein a plurality of limiting rings 5 are evenly fixed on the surface of the sieve plate 3, and the limiting rings 5 and the sieve holes 4 are staggered.
[0022] A feed barrel 6 located above the sieve plate 3 is fixed inside the main body 1, and the feed barrel 6 and the main body 1 are fixedly connected at four corners by connecting blocks 2, the edge of the sieve plate 3 and the main body 1 are elastically connected by a rubber ring 16, and a high-quality seed discharge hole 7 located above the rubber ring 16 is opened between the feed barrel 6 and the main body 1, a discharge inclined plate 8 is fixed at an angle inside the main body 1, and a discharge pipe 9 matched with the discharge inclined plate 8 is fixed on one side of the main body 1, the high-quality large-particle seeds will gradually diffuse and move around with the overall vibration of the sieve plate 3, and then can enter the main body 1 through the high-quality seed discharge hole 7, and since the discharge inclined plate 8 is inclined, the high-quality rapeseed seeds are discharged to the outside through the discharge pipe 9.
[0023] A low-quality seed discharge hole 18 is provided at the bottom of the main body 1, and the low-quality seed discharge hole 18 is located below the sieve plate 3. The sieve plate 3 is arranged inside the main body 1, wherein a plurality of groups of sieve holes 4 are evenly provided inside the sieve plate 3. As the sieve plate 3 vibrates up and down reciprocatingly, low-quality small-particle seeds will pass through the sieve holes 4 and be discharged to the outside through the low-quality seed discharge hole 18.
[0024] A support rod 10 is fixed at the center position of the bottom of the sieve plate 3, a mounting cylinder 11 is fixed at the bottom of the support rod 10, and a vibration motor 12 is installed inside the mounting cylinder 11, a spring 13 is elastically connected between the mounting cylinder 11 and the main body 1, and a guide rod located inside the spring 13 is slidably connected between the main body 1 and the mounting cylinder 11.
[0025] See also Figure 2 and Figure 3 A fixing cylinder 15 located outside the mounting cylinder 11 is fixed to the bottom of the main body 1, and a connecting guide cylinder 14 with the end extending to the inside of the fixing cylinder 15 is fixed to the bottom of the sieve plate 3. The utility model arranges the above structure, wherein the connecting guide cylinder 14 reciprocates up and down with the sieve plate 3, and under the action of the fixing cylinder 15, the stability of the vibration process of the sieve plate 3 is further guaranteed to avoid the phenomenon of deviation.
[0026] See also Figure 2 and Figure 4 Support legs 17 are fixed at the four corners of the bottom of the main body 1, and support rings are fixed at the bottom of the four groups of support legs 17. The utility model is provided with the above structure, wherein the support legs 17 play a supporting and fixing role for the main body 1, making it more stable during operation.
[0027] The working principle of the utility model is as follows: when in use, the power is turned on, and rapeseeds to be screened are put in through the feed tube 6 so that the rapeseeds fall onto the surface of the screen plate 3 .
[0028] A sieve plate 3 is arranged inside the main body 1, wherein a plurality of sieve holes 4 are evenly arranged inside the sieve plate 3. As the sieve plate 3 vibrates up and down reciprocatingly, inferior small-particle seeds will pass through the sieve holes 4 and be discharged to the outside through the inferior seed discharge hole 18.
[0029] The high-quality large-grained seeds will gradually spread and move around as the screen plate 3 vibrates as a whole, and then can enter the interior of the main body 1 through the high-quality seed discharge hole 7. Since the discharge inclined plate 8 is inclined, the high-quality rapeseed seeds can be discharged to the outside through the discharge pipe 9.
[0030] Furthermore, the edge of the sieve plate 3 and the main body 1 are connected by a rubber ring 16, and the rubber ring 16 has a certain elasticity, so that high-quality large-grain seeds can pass through the rubber ring 16 and enter the interior of the main body 1 from the high-quality seed discharge hole 7, and the rubber ring 16 will not affect the reciprocating up and down vibration of the sieve plate 3.
[0031] From the above, it can be seen that after the utility model screens the rapeseed seeds, there is no need to take out the high-quality seeds separately again. The overall operation is relatively simple, and the overall rapeseed seed screening continuity is good, which greatly improves the screening efficiency of the rapeseed seeds.
[0032] Specifically, the bottom of the screen plate 3 is connected to a mounting tube 11 through a support rod 10, wherein a vibration motor 12 is installed inside the mounting tube 11, and the vibration motor 12 adopts a dual-axis motor, and eccentric wheels are fixed on the outer sides of its two sets of output shafts, and then as the vibration motor 12 drives the two sets of eccentric wheels to rotate, an overall vibration effect can be generated.
[0033] The surface of the sieve plate 3 is provided with a limiting ring 5 protruding from the upper surface of the sieve plate 3. The limiting ring 5 is staggered with the sieve hole 4 to avoid blocking the sieve hole 4. The limiting ring 5 can effectively prevent the risk of low-quality small particles sliding directly along the surface of the sieve plate 3 into the high-quality seed discharge hole 7, thereby improving the screening accuracy. The height of the limiting ring 5 can be designed according to the screening standard adaptability, so that high-quality seeds with larger sizes can effectively pass through the limiting ring 5, while limiting the low-quality seeds with smaller sizes within the limiting range of the limiting ring 5, and fall through the sieve hole to the bottom of the sieve plate 3 as the screening proceeds.
[0034] Furthermore, the bottom of the mounting cylinder 11 and the main body 1 are elastically connected via a spring 13, so that the vibration generated by the vibration motor 12 will not be transmitted to the main body 1, but only drives the screen plate 3 to vibrate reciprocatingly up and down.
[0035] In order to prevent rapeseed seeds from bouncing when they fall onto the sieve plate 3 during feeding, causing some low-quality small particles to be directly bounced to the high-quality seed discharge hole 7 without being screened, the feeding impulse needs to be adaptively controlled. A deceleration grid can be set on the feeding path to reduce the impact force of rapeseed seeds falling onto the sieve plate 3, thereby ensuring the effectiveness of screening. At the same time, the feeding speed also needs to be adaptively controlled to avoid excessive feeding, which leads to the accumulation of rapeseed seeds, and the excessive seeds cannot be effectively screened and are discharged to the high-quality seed discharge hole 7. The actual feeding speed needs to be adaptively adjusted according to the actual size of the equipment and the actual working conditions, which will not be described in detail in this application.
[0036] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
