[0002] A screening device for broad bean breeding raw materials is usually a device used to screen, separate, and select high-quality seeds from broad bean seeds. Such devices can help breeders screen out broad bean raw material seeds that meet specific breeding requirements, remove impurities and unqualified seeds, so as to provide high-quality seed raw materials for subsequent breeding research and production.
[0003] In the prior art, when some screening devices for broad bean breeding raw materials are feeding, broad beans are poured into the screening device to perform shell-breaking screening on broad bean shells. If the user operates improperly, a large number of broad beans may be directly poured into the screening device for shell-breaking screening at one time. A large number of broad beans may block in the feeding box, which may cause poor material flow, or even complete blockage, resulting in the device being unable to operate normally. It may require manual intervention or shutdown to clean the blockage, causing production interruption and affecting work efficiency. For this reason, we propose a screening device for broad bean breeding raw materials. Summary of the Invention

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0025] Embodiment 1
[0026] Please refer to Figures 1 to 8, the present invention provides a technical solution: a screening device for broad bean breeding raw materials, including a base 1. The base 1 is designed to facilitate the fixation of the screening mesh 4 and the fan 5. The outer side of the base 1 is fixedly connected with a mounting frame 2. The mounting frame 2 is designed to facilitate the installation of the feeding box 3. The top of the mounting frame 2 is fixedly connected with the feeding box 3. A large number of broad beans are stored inside the feeding box 3. The top of the base 1 is fixedly connected with a screening mesh 4. The screening mesh 4 is designed to screen the broad beans. The top of the base 1 is fixedly connected with a fan 5. The fan 5 is designed to blow the screening mesh 4. Inside the feeding box 3, there are three crushing rods 6 rotatably connected. The crushing rods 6 are designed to crush the outer shells of the falling broad beans. On the left side of one of the crushing rods 6, there is a fixedly connected motor 7. The motor 7 is designed to drive one of the crushing rods 6. On the right side of the three crushing rods 6, there is a driving gear 8 fixedly connected. The driving gear 8 is designed to enable one crushing rod 6 to drive the other two crushing rods 6 through the driving gear 8. Inside the feeding box 3, there is a baffle 9 rotatably connected. The baffle 9 is designed to prevent a large amount of broad beans in the feeding box 3 from falling. Inside the feeding box 3, there is a push rod 10 slidably connected. The push rod 10 is designed to push the baffle 9 under the push of the first push spring 11, or to drive the adjusting column 1303 and the pressing push ring 1806. The outer side of the push rod 10 is slidably connected inside the baffle 9. The outer side of the push rod 10 is sleeved with the first push spring 11. The first push spring 11 is designed to push the push rod 10, thereby pushing the baffle 9. The front side of the feeding box 3 is fixedly connected with a mounting seat 12. The mounting seat 12 is designed to facilitate the installation of the sliding rheostat 1301 and the power-on button 1808. At the bottom of the mounting seat 12, there is a power adjustment mechanism 13 for adjusting the power of the fan 5. On the front side of the feeding box 3, there is a driving mechanism 18 for adjusting the tightness of the transmission belt 15.
[0027] On the right side of one of the driving gears 8, there is a first transmission wheel 14 fixedly connected. The first transmission wheel 14 is designed to drive the transmission belt 15 under the drive of the driving gear 8, thereby driving the second transmission wheel 17 to rotate. The outer side of the first transmission wheel 14 is sleeved with the transmission belt 15. The transmission belt 15 is designed to facilitate the first transmission wheel 14 to drive the second transmission wheel 17. Inside the feeding box 3, there is a dredging rod 16 rotatably connected. The dredging rod 16 is designed to dredge the broad beans falling into the feeding box 3 to prevent the broad beans from being blocked. On the right side of the dredging rod 16, there is a second transmission wheel 17 fixedly connected. The second transmission wheel 17 is designed to drive the dredging rod 16. The transmission belt 15 is sleeved on the outer side of the second transmission wheel 17.
[0028] The driving mechanism 18 includes a fixing frame 1801 fixedly connected to the front side of the blanking box 3. The fixing frame 1801 is designed to fix the electromagnet 1802. The front end of the fixing frame 1801 is fixedly connected with the electromagnet 1802. The electromagnet 1802 is designed to attract the pushing ring 1806 when electrified, so as to pull the whole mounting rod 1803.
[0029] A mounting rod 1803 is slidably connected inside the electromagnet 1802. The mounting rod 1803 is designed to facilitate the installation of the tensioning wheel 1804. A tensioning wheel 1804 is rotatably connected to the outside of the mounting rod 1803. The tensioning wheel 1804 is designed to tighten the transmission belt 15 under the drive of the mounting rod 1803. The transmission belt 15 is sleeved on the outside of the tensioning wheel 1804.
[0030] A second pushing spring 1805 is sleeved on the mounting rod 1803. The second pushing spring 1805 is designed to push the pushing ring 1806, so as to reset the mounting rod 1803. The mounting rod 1803 is fixedly connected with the pushing ring 1806. A second wire 1807 is fixedly connected to the outside of the electromagnet 1802. The second wire 1807 is designed to facilitate the switching on and off of the electromagnet 1802. An electrifying button 1808 is fixedly connected to the top of the mounting seat 12. After the electrifying button 1808 is pressed down, the second wire 1807 will electrify the electromagnet 1802. One end of the second wire 1807 is fixedly connected to the outside of the electrifying button 1808.
[0031] A protection chamber 19 is fixedly connected to the right side of the blanking box 3. The protection chamber 19 is designed to prevent dust from the three driving gears 8. A magnetic column 20 for attracting the transmission belt 15 is fixedly connected to the right side of the protection chamber 19. The magnetic column 20 is designed to attract the steel wire inside the transmission belt 15 when the transmission belt 15 is loose, so as to pull the transmission belt 15 and prevent the first transmission wheel 14 from driving the transmission belt 15 to rotate.
[0032] When the screening device for broad bean breeding raw materials is needed, pour the broad beans into the inside of the feeding box 3. The baffle 9 obstructs the broad beans inside the feeding box 3 to prevent a large amount of broad beans from being broken and screened at one time. The motor 7 drives the middle crushing rod 6 to rotate. The middle crushing rod 6 drives the other two crushing rods 6 under the influence of three driving gears 8, so that the crushing rods 6 break the outer shells of the broad beans. The broad beans with broken outer shells will fall on the screening mesh 4 for screening, so as to select seeds of appropriate size. In this process, when the baffle 9 is squeezed more, it means that more broad beans are put into the feeding box 3. At this time, the baffle 9 drives the push rod 10 to move forward. The forward moving push rod 10 presses down the power-on button 1808, so that the push ring 1806 energizes the electromagnet 1802 through the second wire 1807. The energized electromagnet 1802 attracts the iron mounting rod 1803, thereby driving the tensioning wheel 1804 to tighten the loose transmission belt 15. At this time, the transmission belt 15 will drive the second transmission wheel 17 to rotate under the drive of the first transmission wheel 14. The rotating second transmission wheel 17 drives the dredging rod 16 to stir the broad beans in the feeding box 3 to prevent the broad beans from being blocked. Moreover, the sliding groove 1304 driven forward by the baffle 9 drives the adjusting column 1303 through the sliding groove 1304, so that the adjusting column 1303 can drive the adjusting component on the sliding rheostat 1301. At this time, the farther the adjusting column 1303 moves forward, the greater the current flowing through the first wire 1302 to the blower 5, and the greater the power of the blower 5, which can blow up the broken shells falling on the screening mesh 4 to prevent the broken shells from blocking the sieve holes on the screening mesh 4. By letting the push rod 10 press the power-on button 1808, the electromagnet 1802 is energized, the electromagnet 1802 attracts the push ring 1806, thereby pulling the mounting rod 1803 and the tensioning wheel 1804, making the tensioning wheel 1804 tighten the loose transmission belt 15, enabling the first transmission wheel 14 to drive the second transmission wheel 17 and the dredging rod 16 through the transmission belt 15, and making the dredging rod 16 dredge the broad beans in the feeding box 3 to prevent the broad beans from being blocked, ensuring the normal operation of the screening device and improving the screening efficiency.
[0033] Embodiment 2
[0034] In this Embodiment 2, other structures remain unchanged. Different from Embodiment 1, the power adjustment mechanism 13 includes a sliding rheostat 1301 fixedly connected to the bottom end of the mounting seat 12. The sliding rheostat 1301 is designed to adjust the power of the screening mesh 4. A first wire 1302 is fixedly connected inside the sliding rheostat 1301. The first wire 1302 is designed to supply power to the blower 5. The blower 5 can automatically adjust the voltage according to the magnitude of the current passing through the first wire 1302. One end of the first wire 1302 is fixedly connected to the outside of the blower 5.
[0035] The interior of the mounting base 12 is slidably connected with an adjusting column 1303 for driving the adjusting component on the sliding rheostat 1301. The adjusting column 1303 can be affected by the push rod 10 to drive the components on the sliding rheostat 1301, thereby adjusting the magnitude of the current in the first wire 1302 after passing through the sliding rheostat 1301. A sliding groove 1304 is formed inside the power adjustment mechanism 13. The outside of the adjusting column 1303 is slidably connected inside the sliding groove 1304. The design of the sliding groove 1304 is to facilitate the sliding of the first wire 1302.
