In order to strengthen the promotion of agricultural technology, promote the application of agricultural scientific research results and practical technologies in agricultural production as soon as possible, ensure the development of agriculture, and realize agricultural modernization, this law is formulated. At present, seed screening equipment is needed in agricultural technology.

[0003] At present, the screening method of seed screening devices is relatively simple, mainly relying on particle size for screening, and filtering out impurities such as gravel and fine sand. However, some light impurities such as seed coats cannot be effectively removed. During the screening process, the seeds cannot be dried at the same time, and the screening effect of seeds with moisture is not ideal. In addition, seeds of different specifications cannot be screened, resulting in poor screening effect. Therefore, it is necessary to propose a seed screening equipment for agricultural technology to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a seed screening device for agricultural technology, which can remove light impurities, can screen seeds while drying them, and can screen seeds of different specifications.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a seed screening equipment for agricultural technology, comprising a bottom plate and a screening box arranged at the upper end of the bottom plate, the upper end of the screening box is provided with a feed port and an anti-blocking component located in the feed port, the inner cavity is provided with a first screening mechanism, a second screening mechanism and a material receiving assembly, and the bottom is provided with a waste collection component, the first screening mechanism comprises a first screen plate, a first motor, a rotating rod, an exhaust pipe, a fan, a dehumidification port and two fixed plates, the first screen plate is horizontally arranged in the screening box, the first motor is installed on the left side wall of the screening box and the output end is connected to the rotating rod, the two fixed plates are symmetrically installed on the inner wall of the screening box front and back, a plurality of first springs connected to the first screen plate are equidistantly arranged at the upper end of the fixed plate, two cams for pushing the first screen plate down are arranged on the outside of the rotating rod, a synchronous belt structure is arranged between the fan and the end of the rotating rod, a heating wire is also arranged in the exhaust pipe, and an exhaust fan and a grille are arranged in the dehumidification port.

[0006] By adopting the above technical scheme, the seeds are fed into the screening box from the feed port, and the anti-blocking component allows the seeds to fall smoothly. The seeds are screened by the first screening mechanism and the second screening mechanism, and light impurities and sand and gravel can be screened out. At the same time, seeds of different specifications can be screened. Finally, the seeds are recovered by the collecting assembly. The waste collection component is used to centrally process the sand and gravel waste. Specifically, when passing through the first screening mechanism, the first motor drives the rotating rod to rotate, and the first screen plate is intermittently pushed down by the cam to make it close to the fixed plate and squeeze the first spring at the bottom. Under the expansion and contraction of the first spring, the first screen plate is continuously vibrated up and down to perform preliminary screening of the seeds. At the same time, the fan is driven to rotate by the synchronous belt structure, and the airflow generated by it is heated by the heating wire and enters the screening box. The hot air can dry the thrown seeds, and at the same time, impurities such as light seed coat can be blown to the left. The generated moisture and light impurities are discharged by the exhaust fan, so that the quality of seed screening is better. The synchronous belt structure includes synchronous wheels arranged at the ends of the rotating rod and the fan, and the synchronous belt is connected between the two synchronous wheels.

[0007] The present invention is further configured as follows: the anti-blocking component includes a second motor installed on the rear side of the screening box, a driving rod is installed on the output end of the second motor, and a plurality of stirring blades are arranged on the outer circumference of the driving rod.

[0008] By adopting the above technical solution, the second motor rotates the driving rod, driving the stirring blade to rotate, so that the seeds can smoothly fall onto the first screen plate for screening.

[0009] The present invention is further configured as follows: the second screening mechanism comprises a second sieve plate arranged parallel to and below the first sieve plate and a shaking component for controlling vibration of the second sieve plate, and material blocking structures are arranged on both left and right sides of the second sieve plate.

[0010] By adopting the above technical solution, the first sieve plate retains large-volume seeds on the upper side, and small-volume seeds and fine sand fall onto the second sieve plate. The sieve is continuously shaken by a shaking component to make the fine sand fall, and smaller-volume seeds remain on the second sieve plate. The setting of the material retaining structure prevents seeds from falling from both sides during the screening process.

[0011] The present invention is further configured as follows: the material blocking structure comprises a material blocking frame slidably arranged on the side wall of the screening box, and a plurality of second springs connected to the inner wall of the screening box are installed on the inner side of the material blocking frame.

[0012] By adopting the above technical solution, when the second sieve plate swings left and right, the material blocking frame can be pushed outward to compress the second spring, and the material blocking frame is always in contact with the end of the second sieve plate to prevent seeds from falling from both sides.

[0013] The present invention is further configured as follows: the shaking component includes a dual-axis motor and a vibration frame arranged below the second sieve plate, push rods are installed at the output ends on both sides of the dual-axis motor, a push wheel is installed at the other end of the push rod, a connecting plate connected to the second sieve plate is installed at the upper end of the dual-axis motor, and two fixing bars located directly below the push wheel are provided at the bottom of the inner cavity of the screening box.

[0014] By adopting the above technical solution, the double-axis motor drives the push rods on both sides to rotate, driving the push wheels at the ends to rotate. With the cooperation of the fixed bar, the double-axis motor and the connecting plate vibrate up and down continuously, thereby driving the second screening at the upper end to vibrate for screening.

[0015] The present invention is further configured as follows: two guide rods are symmetrically installed on the left and right ends of the inner side of the vibration frame, the left and right side walls of the dual-axis motor are installed with guide blocks that are slidably adapted to the guide rods, and the outer side of the guide rod is sleeved with two third springs that abut against the guide blocks.

[0016] By adopting the above technical solution, during the up and down reciprocating movement of the dual-axis motor and the connecting plate, the two guide blocks at the end are always sliding on the guide rods, and the vibration effect of the second screen plate is better through the expansion and contraction of the third spring.

[0017] The present invention is further configured as follows: two limit rods slidably connected to the screening box are installed on the left and right side walls of the vibration frame, a stopper is installed between the other ends of the upper and lower limit rods, and a fourth spring is sleeved on the part of the limit rod located in the screening box.

[0018] By adopting the above technical solution, the push wheel will cooperate with the fixed bar and drive it to move left and right, so that the vibration frame drives the limit rod to move. Under the squeezing and buffering of the fourth spring, the whole can swing left and right. The second screen plate vibrates up and down and swings left and right at the same time, so that the screening effect is better.

[0019] The present invention is further configured as follows: the material collecting assembly includes a rectangular frame arranged on the outer wall of the first sieve plate and the second sieve plate, one end of the first sieve plate and the second sieve plate are hinged to the rectangular frame, and a support block is arranged on the inner side of the rectangular frame, and two first electric push rods connected to the first sieve plate are installed at the front end of the bottom of the rectangular frame at the upper end, and four telescopic rods are arranged between the first sieve plate and the second sieve plate.

[0020] By adopting the above technical solution, after screening is completed, the first electric push rod is driven to tilt the first sieve plate at the upper end, and the second sieve plate at the lower end is driven to tilt through the telescopic rod, so that the seeds on the sieve plate are poured out for collection.

[0021] The present invention is further configured as follows: the telescopic rod comprises a connecting column installed on the opposite side of the first screen plate and the second screen plate, the outer sliding sleeves at the ends of the two connecting columns are provided with limit sleeves, and the connecting column is provided with four sliding blocks slidably adapted thereto at one end extending into the limit sleeve, and the front end of the screening box is provided with two discharge ports and a receiving bin located at the discharge port.

[0022] By adopting the above-mentioned technical scheme, during the inclination of the first sieve plate, the connecting column at the upper end is driven to move upward, and with the cooperation of the limiting sleeve and the sliding block, the connecting column at the lower end drives the second sieve plate at the bottom to tilt as well, thereby pouring the seeds on the sieve plate into the corresponding receiving bin for collection. In this application, the connection method between the connecting column and the first sieve plate and the second sieve plate adopts a movable connection, which can avoid the problem of contradictions in the operation of the structure. Its specific implementation method is relatively simple, so this application will not provide a specific description.

[0023] The present invention is further configured as follows: the waste collecting component includes two second electric push rods arranged at the rear end of the screening box, a material receiving box is arranged between the output ends of the two second electric push rods, and a moving wheel is arranged at the bottom of the material receiving box.

[0024] By adopting the above technical solution, during the process of screening seeds, the sand and gravel fragments produced fall into the material receiving box, and are then pushed out through the cooperation of the second electric push rod and the moving wheel, thereby facilitating their cleaning.

[0025] The beneficial effects of the present invention are:

[0026] 1. The present invention drives the rotating rod to rotate through the first motor, and intermittently pushes the first screen plate down through the cam, so that it approaches the fixed plate and squeezes the first spring at the bottom. Under the expansion and contraction of the first spring, the first screen plate is continuously vibrated up and down to perform preliminary screening of the seeds. At the same time, the fan is driven to rotate through the synchronous belt structure, and the airflow generated by it is heated by the heating wire and enters the screening box. The hot air can dry the thrown seeds and blow impurities such as light seed coat to the left. The exhaust fan discharges the generated moisture and light impurities, so that the quality of seed screening is better.

[0027] 2. In the present invention, a double-axis motor drives the push rods on both sides to rotate, which drives the push wheels at the end to rotate. With the cooperation of the fixed bar, the double-axis motor and the connecting plate are continuously vibrated up and down, thereby driving the second screening at the upper end to vibrate. While the push wheel cooperates with the fixed bar, it also drives it to move left and right, so that the vibration frame drives the limit rod to move. Under the extrusion and buffering of the fourth spring, the whole can produce left and right shaking. The second screen plate vibrates up and down and shakes left and right at the same time, so that the screening effect is better, so that the device can screen seeds of different specifications, and the applicability is stronger.

[0028] 3. After screening is completed, the present invention drives the first electric push rod to tilt the first sieve plate at the upper end, driving the connecting column at the upper end to move upward, and with the cooperation of the limiting sleeve and the sliding block, the connecting column at the lower end drives the second sieve plate at the bottom to tilt as well, thereby pouring the seeds on the sieve plate into the corresponding receiving bin for collection, making the device more convenient to use.

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a seed screening device for agricultural technology comprises a bottom plate 1 and a screening box 2 arranged at the upper end of the bottom plate 1, the upper end of the screening box 2 is provided with a feed port 3 and an anti-blocking component located in the feed port 3, the inner cavity is provided with a first screening mechanism 4, a second screening mechanism 5 and a material receiving assembly 6, and the bottom is provided with a waste collecting component 7, the first screening mechanism 4 comprises a first screen plate 41, a first motor 42, a rotating rod 43, an exhaust duct 44, a fan 45, a dehumidification port 46 and two fixed plates 47, the first screen plate 41 is horizontally arranged in the screening box 2, and the second screening mechanism 5 and the material receiving assembly 6 are provided in the inner cavity, and the waste collecting component 7 is provided at the bottom. The first motor 42 is installed on the left side wall of the screening box 2 and the output end is connected to the rotating rod 43. The two fixed plates 47 are symmetrically installed on the inner wall of the screening box 2 front and back. A plurality of first springs 48 connected to the first sieve plate 41 are equidistantly arranged at the upper end of the fixed plate 47. Two cams 49 for pushing the first sieve plate 41 down are arranged on the outside of the rotating rod 43. A synchronous belt structure 410 is arranged between the fan 45 and the end of the rotating rod 43. A heating wire 411 is also arranged in the exhaust tube 44. An exhaust fan 412 and a grille 413 are arranged in the dehumidification port 46.

[0041] The seeds enter the screening box 2 from the feed port 3. The anti-blocking component allows the seeds to fall smoothly. The seeds are screened by the first screening mechanism 4 and the second screening mechanism 5 to remove light impurities and sand and gravel. At the same time, seeds of different specifications can be screened. Finally, the seeds are recovered by the collecting component 6. The waste collecting component 7 is used to centrally process the sand and gravel waste. Specifically, when passing through the first screening mechanism 4, the first motor 42 drives the rotating rod 43 to rotate, and the cam 49 intermittently pushes the first screen plate 41 downward to make it close to the fixed plate 47 and squeeze the first spring 48 at the bottom. The expansion and contraction of the spring 48 causes the first screen plate 41 to vibrate up and down continuously to perform preliminary screening of the seeds. At the same time, the fan 45 is driven to rotate through the synchronous belt structure 410. The airflow generated is heated by the heating wire 411 and enters the screening box 2. The hot air can dry the thrown seeds and blow impurities such as light seed coats to the left. The exhaust fan 412 discharges the generated moisture and light impurities, thereby improving the quality of seed screening. The synchronous belt structure 410 includes synchronous wheels arranged at the ends of the rotating rod 43 and the fan 45, and a synchronous belt is connected between the two synchronous wheels.

[0042] like Figure 1 , Figure 2 As shown, the anti-blocking component includes a second motor 31 installed on the rear side of the screening box 2, and a driving rod 32 is installed at the output end of the second motor 31. A plurality of stirring blades 33 are arranged on the outer circumference of the driving rod 32; the driving rod 32 is rotated by the second motor 31, driving the stirring blades 33 to rotate, so that the seeds can smoothly fall onto the first screen plate 41 for screening.

[0043] like Figure 3 , Figure 5 , Figure 6 As shown, the second screening mechanism 5 includes a second sieve plate 51 arranged parallel to and below the first sieve plate 41 and a shaking component for controlling the vibration of the second sieve plate 51, and a material blocking structure is arranged on both sides of the left and right sides of the second sieve plate 51, and the material blocking structure includes a material blocking frame 52 slidably arranged on the side wall of the screening box 2, and a plurality of second springs 53 connected to the inner wall of the screening box 2 are installed on the inner side of the material blocking frame 52.

[0044] The first sieve plate 41 retains large-volume seeds on the upper side, and small-volume seeds and fine sand fall onto the second sieve plate 51. The sieve plate 41 is continuously shaken by a shaking component to make the fine sand fall, and smaller-volume seeds remain on the second sieve plate 51. The setting of the material-blocking structure prevents seeds from falling from both sides during the screening process. Specifically, when the second sieve plate 51 is shaken left and right, the material-blocking frame 52 can be pushed outward to compress the second spring 53. The material-blocking frame 52 is always in contact with the end of the second sieve plate 51 to prevent seeds from falling from both sides.

[0045] like Figure 6As shown, the shaking component includes a double-axis motor 54 and a vibration frame 55 arranged below the second sieve plate 51, and the output ends on both sides of the double-axis motor 54 are installed with push rods 56, and the other end of the push rod 56 is installed with a push wheel 57. The upper end of the double-axis motor 54 is installed with a connecting plate 58 connected to the second sieve plate 51, and the bottom of the inner cavity of the screening box 2 is provided with two fixing bars 59 located directly below the push wheel 57, and the left and right ends of the inner side of the vibration frame 55 are symmetrically installed with two guide rods 510 The left and right side walls of the dual-axis motor 54 are both equipped with guide blocks 511 that are slidably adapted to the guide rod 510, and the outer side of the guide rod 510 is sleeved with two third springs 512 that abut against the guide blocks 511. The left and right side walls of the vibration frame 55 are both equipped with two limit rods 513 that are slidably connected to the screening box 2, and a stopper 514 is installed between the other ends of the upper and lower limit rods 513. The limit rod 513 is sleeved with a fourth spring 515 in the part located in the screening box 2.

[0046] The push rods 56 on both sides are driven to rotate by the double-axis motor 54, which drives the push wheel 57 at the end to rotate. With the cooperation of the fixed bar 59, the double-axis motor 54 and the connecting plate 58 are continuously vibrated up and down, thereby driving the second screen 51 at the upper end to vibrate and perform screening. In the process of the double-axis motor 54 and the connecting plate 58 reciprocating up and down, the two guide blocks 511 at the end are always sliding on the guide rod 510. Through the expansion and contraction of the third spring 512, the vibration effect of the second screen plate 51 is better. When the push wheel 57 cooperates with the fixed bar 59, it will also drive it to move left and right, so that the vibration frame 55 drives the limit rod 513 to move. Under the compression and buffering of the fourth spring 515, the whole can produce left and right shaking. The second screen plate 51 vibrates up and down and shakes left and right at the same time, so that its screening effect is better.

[0047] like Figure 1 , Figure 4 , Figure 7 As shown, the material receiving assembly 6 includes a rectangular frame 61 arranged on the outer wall of the first sieve plate 41 and the second sieve plate 51, one end of the first sieve plate 41 and the second sieve plate 51 are hinged to the rectangular frame 61, and a support block 62 is arranged on the inner side of the rectangular frame 61, and two first electric push rods 63 connected to the first sieve plate 41 are installed at the front end of the bottom of the rectangular frame 61 at the upper end, and four telescopic rods are arranged between the first sieve plate 41 and the second sieve plate 51, and the telescopic rods include connecting columns 64 installed on the opposite sides of the first sieve plate 41 and the second sieve plate 51, and the outer sliding sleeves of the ends of the two connecting columns 64 are provided with limit sleeves 65, and the connecting column 64 is provided with four sliding blocks 66 slidably adapted thereto at one end extending into the limit sleeve 65, and the front end of the screening box 2 is provided with two discharge ports and a material receiving bin 67 located at the discharge port.

[0048] After screening is completed, the first electric push rod 63 is driven to tilt the first sieve plate 41 at the upper end, and the second sieve plate 51 at the lower end is driven to tilt through the telescopic rod, so that the seeds on the sieve plate are poured out for collection. During the tilting of the first sieve plate 41, the connecting column 64 at the upper end is driven to move upward, and with the cooperation of the limiting sleeve 65 and the sliding block 66, the connecting column 64 at the lower end drives the second sieve plate 51 at the bottom to tilt as well, so that the seeds on the sieve plate are poured into the corresponding receiving bin 67 for collection. In this application, the connection method of the connecting column 64 and the first sieve plate 41 and the second sieve plate 51 adopts a movable connection, which can avoid the problem of contradictions in the operation of the structure. Its specific implementation method is relatively simple, so this application will not be described in detail.

[0049] like Figure 8 As shown, the waste collecting component 7 includes two second electric push rods 71 ​​arranged at the rear end of the screening box 2, and a material receiving box 72 is arranged between the output ends of the two second electric push rods 71, and a moving wheel 73 is arranged at the bottom of the material receiving box 72; in the process of screening seeds, the sand and gravel fragments generated fall into the material receiving box 72, and are then pushed out by the cooperation of the second electric push rods 71 ​​and the moving wheel 73, so as to facilitate their cleaning.
