Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a rapeseed seed breeding screening device. Background Technology

[0002] Rapeseed is one of my country's most important oilseed crops. Rapeseed seeds, also known as rapeseed pods, are the seeds of the cruciferous crop *Rabedon oleracea*. Rapeseed produces relatively long pods, many of which are plump. The seeds contain 33%–50% oil, varying slightly depending on the type of rapeseed. It is one of China's major oilseed and honey-producing crops, and its seeds are a primary raw material for oil extraction. Besides being used for edible oil and animal feed, rapeseed is also used in the food industry to produce margarine and artificial protein. Because a large number of rapeseed seeds are hollow or defective, they cannot be used for planting. Therefore, rapeseed seeds need to be screened before planting.

[0003] The prior art patent CN220969441U discloses a rapeseed breeding screening device, including a screening box. The inner wall of the screening box is fixedly connected with a first partition and a second partition, and a second filter plate is connected between the screening box and the second partition. A first filter plate is connected between the first partition and the second partition. An overflow port is opened on the outer surface of the second partition. The screening box includes a feeding device for conveying rapeseed seeds into the interior of the screening box, and the feeding device is equipped with a feeding hopper and a servo motor; a circulation device for circulating screening water, and the circulation device is equipped with a circulation pump.

[0004] The aforementioned breeding screening device, through the interconnection of a screening box, a first filter plate, and a second filter plate, is able to perform water screening on the seeds poured into the screening box. However, in actual use, the capacity of the screening box is limited. After screening a certain number of rapeseed seeds, it is necessary to stop screening, remove the rapeseed seeds deposited in the screening box, and then refill the screening water. In other words, the breeding screening device cannot perform continuous screening, cannot screen large quantities of rapeseed seeds, and has low screening efficiency. Utility Model Content

[0005] This invention proposes a rapeseed seed breeding and screening device, which solves the problem that existing breeding and screening devices cannot perform continuous screening or large-scale screening of rapeseed seeds.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A rapeseed seed breeding screening device includes a screening box with an overflow baffle inside. A screening chamber and an overflow chamber are respectively located on both sides of the overflow baffle. An lifting box, communicating with the screening chambers, is located outside the screening box, and a lifting mechanism is installed inside the lifting box. Rapeseed seeds pass through a water sieve in the screening box and settle at the bottom of the screening chambers. The lifting mechanism inside the lifting box lifts and retrieves the rapeseed seeds screened at the bottom of the screening chambers. This allows the screening device to continuously screen rapeseed seeds without being limited by the volume of the screening box, which is beneficial for large-scale screening of rapeseed seeds and improves screening efficiency.

[0008] The lifting mechanism includes a support shaft rotatably mounted inside a lifting box. A drive motor connected to the support shaft is located outside the lifting box. A connecting belt is connected to the support shaft, and a lifting plate is mounted on the connecting belt, which engages with the inner wall of the lifting box. The drive motor drives the support shaft to rotate, which in turn moves the connecting belt. This movement of the connecting belt causes the lifting plate to scoop the rapeseed seeds from the water inside the support box.

[0009] The lifting plate is arranged at an angle on the connecting belt and is equipped with filter holes. The angled arrangement of the lifting plate facilitates the downward flow of screening water during seed lifting, and at the same time, the screening water can leak downward from the filter holes, avoiding the scooping out of excessive screening water when lifting rapeseed seeds.

[0010] The bottom of the screening chamber is provided with a second discharge port that communicates with the lifting box. The height of the upper outlet of the lifting box is higher than the height of the overflow baffle. The lifting box is provided with a second discharge hopper corresponding to the upper outlet position. When screening rapeseed seeds, the screening water in the screening chamber can only flow out from the overflow baffle and will not flow out from the upper outlet of the lifting box, ensuring the stable operation of the screening device.

[0011] The screening chamber has a first guide plate arranged at an incline at its lower part. The upper end of the first guide plate is connected to the lower edge of the overflow baffle. A second guide plate is symmetrically arranged at the lower end of the first guide plate, and a third guide plate is located between the two second guide plates. The third guide plate corresponds to the position of the second discharge port. After the rapeseed seeds pass through the screening chamber, the plump and qualified rapeseed seeds will sink downwards. Under the action of the first, second, and third guide plates, the rapeseed seeds will gather at the position of the second discharge port, thus allowing the rapeseed seeds to enter the lifting box.

[0012] The overflow chamber is equipped with an inclined filter plate with filter holes. The screening box has a first discharge port, and the lower end of the filter plate corresponds to the position of the first discharge port. During screening, the screening water in the screening chamber carries the hollow bad seeds over the overflow baffle and flows into the overflow chamber. The overflowing screening water leaks out from the filter holes, and the screened hollow bad seeds are discharged from the first discharge port.

[0013] The outer side of the screening box is equipped with a first discharge hopper corresponding to the position of the first discharge port. The first discharge hopper facilitates the collection of hollow and damaged seeds.

[0014] The screening box also includes a reflux chamber, located below the screening chamber and overflow chamber. The reflux chamber is connected to the overflow chamber, and the screening chamber and reflux chamber are connected via a reflux assembly. The screening water entering the overflow chamber flows into the reflux chamber through the filter holes. The screening water in the reflux chamber then re-enters the screening chamber through the reflux assembly for rapeseed seed screening, facilitating the reuse of screening water and saving water.

[0015] The reflux assembly includes a water pump disposed within a reflux chamber and a second reflux pipe disposed within a screening chamber. A first reflux pipe is connected to the water pump, and the first reflux pipe passes through a first guide plate and communicates with the second reflux pipe. The second reflux pipe is provided with a reflux outlet. The water pump transports the screening water in the reflux chamber to the screening chamber through the first and second reflux pipes, and discharges it through the reflux outlet.

[0016] The second return pipe is located at the connection between the first guide plate and the overflow baffle, and the return outlet is arranged downward along the inclined direction of the first guide plate. The screening water discharged from the return outlet can flush the first guide plate, preventing rapeseed seeds entering the screening chamber from accumulating on the first guide plate, thus facilitating the collection of rapeseed seeds.

[0017] The beneficial effects of this utility model are as follows: 1. An lifting box connected to the screening chamber is set outside the screening box. When screening rapeseed seeds, high-quality and plump rapeseed seeds will sink to the bottom of the screening chamber. The lifting mechanism inside the lifting box will lift and scoop out the screened rapeseed seeds, so that the screening device can continuously screen rapeseed seeds without being limited by the volume of the screening box. This is conducive to large-scale screening of rapeseed seeds and improves screening efficiency.

[0018] 2. A reflux chamber is set inside the screening box. The screening water that overflows during screening can be re-entered into the screening chamber through the reflux component to screen rapeseed seeds, which facilitates the reuse of screening water and saves water.

[0019] 3. When the reflux assembly delivers screening water to the screening chamber, the reflux outlet is arranged downward along the inclined direction of the first guide plate. The screening water discharged from the reflux outlet can flush the first guide plate, preventing rapeseed seeds entering the screening chamber from accumulating on the first guide plate, thus facilitating the collection of rapeseed seeds.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1, such as Figure 1 , Figure 2 , Figure 3As shown, a rapeseed breeding screening device includes a screening box 1, an overflow baffle 13 inside the screening box 1, and screening chambers and overflow chambers on both sides of the overflow baffle 13, respectively. An lifting box 2, communicating with the screening chambers, is located outside the screening box 1, and a lifting mechanism is located inside the lifting box 2. Support legs 11 are provided at the bottom of the screening box 1 to support it and ensure the stability of the screening device during use. During screening, screening water is injected into the screening chamber, and then rapeseed seeds to be screened are placed into the screening chamber. High-quality, plump rapeseed seeds settle downwards, while hollow, defective seeds float on the surface. Screening water is continuously added, carrying the hollow, defective seeds over the overflow baffle 13 into the overflow chamber, thus achieving rapeseed seed screening. The rapeseed seeds deposited in the screening chamber are lifted and retrieved by the lifting mechanism inside the lifting box 2, enabling the screening device to continuously screen rapeseed seeds without being limited by the volume of the screening box 1. This facilitates large-scale screening of rapeseed seeds and improves screening efficiency.

[0029] Furthermore, such as Figure 4 As shown, the lifting mechanism includes a support shaft 23 rotatably mounted inside the lifting box 2. A drive motor 22 connected to the support shaft 23 is located outside the lifting box 2. A connecting belt 24 is connected to the support shaft 23, and a lifting plate 25 is mounted on the connecting belt 24. The lifting plate 25 engages with the inner wall of the lifting box 2. The drive motor 22 drives the support shaft 23 to rotate, which in turn drives the connecting belt 24 to move. The movement of the connecting belt 24 causes the lifting plate 25 to scoop the rapeseed seeds that have entered the support box 2 from the water.

[0030] Furthermore, the lifting plate 25 is arranged at an angle on the connecting belt 24, and the lifting plate 25 is provided with water filtering holes. The angled arrangement of the lifting plate 25 facilitates the downward flow of screening water during the seed lifting process, and at the same time, the screening water can leak downward from the water filtering holes, avoiding the scooping out of excessive screening water when lifting rapeseed seeds.

[0031] Furthermore, a second discharge port connected to the lifting box 2 is provided at the bottom of the screening chamber, and the height of the upper outlet of the lifting box 2 is higher than the height of the overflow baffle 13; when screening rapeseed seeds, the screening water in the screening chamber can only flow out from the overflow baffle 13, and will not flow out from the upper outlet of the lifting box 2, ensuring the stable operation of the screening device. A second discharge hopper 21 corresponding to the upper outlet position is provided on the lifting box 2. The second discharge hopper 21 facilitates the collection of the screened high-quality, plump rapeseed seeds by the staff.

[0032] Example 2 differs from Example 1 in that a rapeseed seed breeding screening device has a water outlet at the bottom of the lifting box 2, and a valve at the water outlet to control the opening and closing of the water outlet. After the screening device is used, the valve can be opened to allow the screening water in the screening chamber to enter the lifting box 1 through the second discharge port, and then be discharged through the water outlet, facilitating the cleaning of the screening device and the replacement of the screening water.

[0033] Example 3, based on Example 1, provides a rapeseed seed breeding and screening device, such as... Figure 5 As shown, the lower part of the screening chamber is provided with an inclined first guide plate 12. The upper end of the first guide plate 12 is connected to the lower edge of the overflow baffle 13. The lower end of the first guide plate 12 is provided with symmetrically arranged second guide plates 17. A third guide plate 18 is provided between the two second guide plates 17, and the third guide plate 18 corresponds to the position of the second discharge port. Both the second guide plates 17 and the third guide plate 18 are inclined. The two second guide plates 17 have a funnel-shaped opening. The third guide plate 18 is located on the lower side of the second guide plates 17. After the rapeseed enters the screening chamber, the settled rapeseed slides down along the first guide plate 12, the second guide plate 17 and the third guide plate 18, and finally enters the lifting box 2 through the second discharge port, realizing the aggregation of rapeseed and avoiding the accumulation of rapeseed in the screening chamber.

[0034] Furthermore, an inclined filter plate 14 is provided inside the overflow chamber, with water-filtering holes on the filter plate 14. The screening box 1 has a first discharge port 15, with the lower end of the filter plate 14 corresponding to the position of the first discharge port 15. During screening, the screening water in the screening chamber carries the hollow bad seeds over the overflow baffle 13 and flows into the overflow chamber. The overflowing screening water leaks out from the water-filtering holes on the filter plate 14, and the screened hollow bad seeds are discharged from the first discharge port 15. A first discharge hopper 16 corresponding to the position of the first discharge port 15 is provided on the outside of the screening box 1. The first discharge hopper 16 facilitates the collection of hollow bad seeds by the staff.

[0035] Example 4, based on Example 3, provides a rapeseed seed breeding screening device. The screening box 1 further includes a reflux chamber located below the screening chamber and overflow chamber, connected to each other. The screening chamber and reflux chamber are connected via a reflux assembly 3. Screening water entering the overflow chamber enters the reflux chamber through filter holes. Screening water in the reflux chamber re-enters the screening chamber through the reflux assembly for rapeseed seed screening, facilitating water reuse and saving water.

[0036] Furthermore, the reflux assembly 3 includes a water pump 31 disposed within the reflux chamber and a second reflux pipe 33 disposed within the screening chamber. A first reflux pipe 32 is connected to the water pump 31, and the first reflux pipe 32 passes through a first guide plate 12 and communicates with the second reflux pipe 33. A reflux outlet 34 is provided on the second reflux pipe 33. The water pump 31 transports the screening water in the reflux chamber to the screening chamber through the first reflux pipe 32 and the second reflux pipe 33, and discharges it through the reflux outlet 34.

[0037] Furthermore, the second return pipe 33 is located at the connection between the first guide plate 12 and the overflow baffle 13, and the return outlet 34 is arranged downward along the inclined direction of the first guide plate 12. The screening water discharged from the return outlet 34 can flush the first guide plate 12, preventing rapeseed seeds entering the screening chamber from accumulating on the first guide plate 12, thus facilitating the collection of rapeseed seeds.

[0038] Example 5, based on Example 4, provides a rapeseed breeding screening device. A feeding hopper is located above the screening box 1, and the outlet of the feeding hopper corresponds to the position of the first guide plate 12. During screening, rapeseed seeds to be screened are added to the feeding hopper and fall into the screening chamber through the hopper outlet for screening.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
