Technical Field
[0001] This utility model relates to the technical field of rapeseed breeding equipment, specifically a seed screening device for rapeseed breeding. Background Technology
[0002] Rapeseed, also known as rapeseed, is the seed of the rapeseed plant, a cruciferous crop. Rapeseed produces relatively long pods, many of which are plump. The oil content of rapeseed ranges from 37.5% to 46.3%, 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. Rapeseed cultivation is widespread in China, divided into winter and spring varieties. Its planting area accounts for over 40% of China's total oilseed crop area, and its yield accounts for over 30% of China's total oilseed production, ranking first in the world. Before breeding, rapeseed seeds need to be screened for different sizes. In current technology, although seeds can be shaken during screening, seeds retained on the screen are difficult to remove. Because the screen is difficult to remove, it is inconvenient to collect the intercepted seeds, requiring tools to continuously shovel them off.
[0003] For example, the authorized patent document with application number CN202223085458.0 discloses a rapeseed seed breeding screening device, which includes a base, side plates fixed on both sides of the top of the base, a sliding groove provided on the inner side of the side plates, and a screening component provided on the upper surface of the base inside the side plates. Sliding rods are fixed on both sides of the screening component and are slidably installed inside the sliding groove.
[0004] The aforementioned patent has the problem that, although the seeds can be shaken and screened during the screening process, the seeds stuck on the screen are difficult to remove. Because the screen is difficult to remove, it is not convenient to collect the intercepted seeds. Therefore, we need to provide a seed screening device for rapeseed breeding. Utility Model Content

[0024] 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.
[0025] Please see Figure 1-4 This utility model provides a technical solution: a seed screening device for rapeseed breeding, comprising:
[0026] The control panel 1, and two filter boxes 2 set on the top of the control panel 1;
[0027] A pushing mechanism 3 is installed on one side of the operating table 1 for the two screening boxes 2 to shake synchronously;
[0028] The operating table 1 is equipped with an assembly mechanism 4 for connecting the pushing mechanism 3 to the two screening boxes 2;
[0029] Specifically, an assembly mechanism 4 for quickly separating two screening frames 2 is installed on the surface of the operating table 1. The design of the quick-separation screening frames 2 can significantly reduce the time consumption in the seed screening process. When a certain number of large seeds accumulate in the screening frames 2, the operator can quickly separate the screening frames 2 and pour out these seeds.
[0030] The driving mechanism 3 includes a driven wheel 31 disposed on one side of the operating table 1. A rod 32 is fixedly installed at the axis of the driven wheel 31. Two fixed seats 33 are rotatably installed on the surface of the rod 32. One side of each of the two fixed seats 33 is fixedly installed on the surface of the operating table 1. Rotating wheels 34 are fixedly installed at the upper and lower ends of the rod 32. Slide rods 35 are fixedly installed at the top and bottom of each of the two rotating wheels 34. The two slide rods 35 are used in conjunction with two assembly mechanisms 4 respectively. A driving component 30 for rotating the driven wheel 31 is installed on one side of the operating table 1.
[0031] In this embodiment, the rapeseed seeds to be screened are poured into the upper screening frame 2, wherein the pores of the upper screening frame 2 are larger than those of the lower screening frame 2. The upper screening frame 2 intercepts larger seeds, while the lower screening frame 2 intercepts smaller seeds. Seeds passing through the lower screening frame 2 fall into the guide plate 6. By rotating the adjusting rod 43, whose surface is threaded onto the mounting frame 42, and ensuring that the contact plate 44 at one end of the adjusting rod 43 does not contact the surface of the screening frame 2, the mounting frame 42 can be pushed upward, causing the push rod 41 to slide on the slide rod 35, thus removing the screening frame 2 for easy screening. The seeds are poured out of the frame 2. The drive motor 302 is started to drive the drive wheel 303 to rotate. The drive wheel 303 and the driven wheel 31 are connected by a toothed belt 304, which drives the driven wheel 31 and the rod 32 to rotate. The rotating wheels 34 at the upper and lower ends of the rod 32 rotate. The movement of the sliding rod 35 on the surface of the rotating wheel 34 will drive the push rod 41 to swing. The push rod 41 is hinged to the mounting frame 42 and can rotate to realize the reciprocating motion of the screening frame 2. Four pulleys 7 are set at the bottom of the screening frame 2. The pulleys 7 slide on the guide rail 8 to make the movement of the screening frame 2 smoother.
[0032] The assembly mechanism 4 includes a push rod 41 that is movably sleeved on the surface of the slide rod 35. One end of the push rod 41 is hinged to a mounting frame 42. The groove at the bottom of the mounting frame 42 is engaged with the edge of the surface of the screening frame 2. An adjusting rod 43 is threadedly installed on one side of the mounting frame 42. One end of the adjusting rod 43 is rotatably mounted with an abutment plate 44. One side of the abutment plate 44 is in contact with the inner wall of the screening frame 2.
[0033] Specifically, the adjusting rod 43 is threaded onto the mounting frame 42. The contact plate 44 at one end of the adjusting rod 43 is not in contact with the surface of the screening frame 2. The mounting frame 42 can be pushed upwards, causing the push rod 41 to slide on the slide rod 35. The screening frame 2 can then be removed, making it convenient to pour out the seeds inside the screening frame 2.
[0034] The drive unit 30 includes a mounting base 301 fixedly installed on one side of the operating table 1. A drive motor 302 is fixedly installed inside the mounting base 301. A drive wheel 303 is installed at the output end of the drive motor 302. The drive wheel 303 and the driven wheel 31 are connected by a toothed belt 304.
[0035] Furthermore, by starting the drive motor 302, the driving wheel 303 is driven to rotate. The driving wheel 303 and the driven wheel 31 are connected by a toothed belt 304, thereby driving the driven wheel 31 and the rod 32 to rotate. The rotating wheels 34 at the upper and lower ends of the rod 32 both rotate. The movement of the sliding rod 35 on the surface of the rotating wheel 34 will cause the push rod 41 to swing.
[0036] Two anti-detachment rings 9 are integrally machined on the surfaces of the two slide rods 35. The push rod 41 is set between the two anti-detachment rings 9, and a reserved groove 10 for sliding of the push rod 41 is installed on one side of the operating table 1.
[0037] It is worth noting that by pushing the mounting frame 42 upward, the push rod 41 can slide on the slide bar 35 and the screening frame 2 can be removed. Since there are two anti-detachment rings 9 on the surface of the slide bar 35, and the push rod 41 is positioned between the two anti-detachment rings 9, it plays a role in preventing the push rod 41 from detaching.
[0038] The bottom of each of the two filter boxes 2 is provided with four pulleys 7, and guide rails 8 are slidably installed on both sides of the filter box 2. The two guide rails 8 are fixedly installed inside the operating table 1, and the bottom of the inner wall of the guide rails 8 is in contact with the bottom of the pulleys 7.
[0039] It should be noted that four pulleys 7 are set at the bottom of the filter box 2. The pulleys 7 slide on the guide rail 8, making the movement of the filter box 2 smoother.
[0040] A flow guide plate 6 is fixedly installed inside the operating table 1, and the flow guide plate 6 is located at the bottom of the two screening boxes 2;
[0041] Specifically, the rapeseed seeds to be screened are poured into the upper screening box 2, where the pores of the upper screening box 2 are larger than those of the lower screening box 2. The upper screening box 2 intercepts larger seeds, while the lower screening box 2 intercepts smaller seeds, and the seeds that pass through the lower screening box 2 fall into the guide plate 6.
[0042] Each of the two filter boxes 2 has a slot 5 on one side, and the slot 5 is engaged with the mounting frame 42.
[0043] A slot 5 is provided on one side of the filter box 2. The slot 5 is engaged with the mounting frame 42 and is used to limit the position of the mounting frame 42.
[0044] The device pours the rapeseed seeds to be screened into the upper screening frame 2, where the pores of the upper screening frame 2 are larger than those of the lower screening frame 2. The upper screening frame 2 intercepts larger seeds, while the lower screening frame 2 intercepts smaller seeds. Seeds passing through the lower screening frame 2 fall into the guide plate 6. By rotating the adjusting rod 43, which is threaded onto the mounting frame 42, and ensuring that the contact plate 44 at one end of the adjusting rod 43 does not contact the surface of the screening frame 2, the mounting frame 42 can be pushed upward, causing the push rod 41 to slide on the slide rod 35. This allows the screening frame 2 to be removed, facilitating the pouring out of the seeds. By starting the drive motor 302, the driving wheel 303 is rotated. The driving wheel 303 and the driven wheel 31 are connected by a toothed belt 304, which in turn drives the driven wheel 31 and the rod body 32 to rotate. The rotating wheels 34 at the upper and lower ends of the rod body 32 also rotate. The movement of the slide rod 35 on the surface of the rotating wheel 34 causes the push rod 41 to swing.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
