[0003] First, the design of the screen is often only able to screen seeds of a specific size. When the seed type needs to be changed, the screen usually needs to be replaced, which not only increases the complexity of the operation, but also reduces the applicability and flexibility of the equipment. Secondly, the screen is prone to seeds clogging the holes during use, resulting in the inability to effectively screen out small-particle seeds, affecting the efficiency and effectiveness of the screening. In addition, most existing screening devices do not have a disinfection function, and the screened seeds need to be transported to special disinfection equipment for disinfection, which increases the operating steps and costs and reduces the overall production and cultivation efficiency.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] See also Figures 1 to 8 , an agricultural seed screening and disinfection device, comprising a frame 1 and a carrier frame 2 fixedly mounted on the upper surface of the frame 1, and further comprising: The screening mechanism 3 is arranged on the top of the carrier frame 2 and is used to screen the seeds. The screening mechanism 3 includes a carrier frame 31. A plurality of strip holes are provided on the bottom plate of the carrier frame 31. A screening assembly 32 is installed on the inner wall of the strip hole. The screening assembly 32 includes two symmetrically arranged sorting plates 321. The surface perpendicular to the length direction of the sorting plates 321 is used as the projection surface. The projections of the two sorting plates 321 on the projection surface are in an inverted eight-shaped shape. An adjusting mechanism 4 is mounted on the carrying frame 31, one side of the adjusting mechanism 4 is connected to a plurality of screening components 32, and the adjusting mechanism 4 is used to adjust the gap size at the bottom of two sorting plates 321 in the screening component 32; The disinfection mechanism 5 is installed at the bottom of the screening mechanism 3 , and is used for receiving the seeds screened by the screening mechanism 3 .

[0021] In the production and cultivation process of existing seeds, it is necessary to first screen the size of the seeds to remove the seeds with smaller particle size. In the prior art, a screen is usually used for screening. When such a screening device is used, it can only screen seeds of the same type. If different types of seeds need to be screened, the screen needs to be replaced, such as soybean seeds and peanut seeds. The applicability of the device is not high, and during use, there is a situation where seeds are stuck in the holes on the screen, resulting in some small-particle seeds cannot be screened out through the screen, resulting in low screening efficiency and poor effect.

[0022] To this end, the present application sets two sorting plates 321 in the screening component 32, and the projection on the projection surface is set in an inverted eight-shaped shape. During screening, the seeds are poured onto the carrier frame 31 and fall between the two sorting plates 321. Seeds that do not meet the particle size fall from between the two sorting plates 321 to achieve seed screening. When it is necessary to adjust the particle size of the screened seeds according to actual screening requirements, the adjustment mechanism 4 can be used to adjust the gap size at the bottom of the two sorting plates 321 in the screening component 32, so that seeds of different particle sizes can be screened out, which can be suitable for screening different types of seeds. Moreover, the existing screening device does not have a disinfection function, and the screened seeds need to be transported to the disinfection device again for disinfection. For this reason, the present application is provided with a disinfection mechanism 5 at the bottom of the screening mechanism 3. Under the screening of the screening component 32, the seeds that meet the particle size will be between the supporting frame 31 and the two sorting plates 321. At this time, the gap size at the bottom of the two sorting plates 321 in the screening component 32 can be enlarged by the adjustment mechanism 4, so that the seeds that meet the particle size can directly fall to the disinfection mechanism 5, thereby improving the production and cultivation efficiency of the seeds.

[0023] In one embodiment of the present invention, a rotating shaft 322 is fixedly installed at both ends of the sorting plate 321, and the outer side wall of the rotating shaft 322 is rotatably connected to the bearing frame 31, so that the sorting plate 321 can rotate around the rotating shaft 322, thereby realizing the adjustment of the inclination angle of the sorting plate 321; The adjustment mechanism 4 is used to drive the two sorting plates 321 in the same screening assembly 32 to rotate synchronously around the axis of the rotating shaft 322 connected thereto, and the rotation directions of the two sorting plates 321 are opposite, that is, the gap size at the bottom of the two sorting plates 321 can be achieved to meet the screening of different types of seeds; In one embodiment of the present invention, the adjustment mechanism 4 includes a swing arm 41 whose one end is fixedly connected to the end of the rotating shaft 322 away from the sorting plate 321, and a slide bar 42 is fixedly installed on the end of the swing arm 41 away from the rotating shaft 322. A driving plate 43 is arranged outside the slide bar 42, and the driving plate 43 is provided with a transverse slide groove 44. The inner wall of the transverse slide groove 44 is slidably connected to the outer wall of the slide bar 42, and a moving driving member 45 is connected to one side of the driving plate 43 to drive it to move in a direction perpendicular to the bottom plate surface of the carrying frame 31; The mobile driving member 45 is two telescopic cylinders, which are respectively arranged at the two ends of the driving plate 43, and the two telescopic cylinders are fixedly mounted on the bearing frame 31, and the moving ends of the two telescopic cylinders are fixedly connected to the driving plate 43; When it is necessary to adjust the gap size at the bottom of the two sorting plates 321, the driving plate 43 is moved by the telescopic end of the telescopic cylinder, and the driving plate 43 moves the inner wall of the horizontal slide groove 44 on it to push the slide bar 42, and the slide bar 42 drives the sorting plate 321 to rotate around the axis of the rotating shaft 322 through the swing arm 41 and the rotating shaft 322, thereby realizing the adjustment of the gap size at the bottom of the two sorting plates 321, which can be effectively applied to different types of seeds.

[0024] In one embodiment of the present invention, two blocking plates 323 are further provided, and the two blocking plates 323 are respectively arranged at the two end portions of the sorting plate 321, and the top ends of the blocking plates 323 are fixedly connected to the supporting frame 31. The size of the gap between the blocking plates 323 and the sorting plate 321 can hinder the passage of seeds with the smallest particles, thereby preventing the seeds from moving out from the ends of the sorting plate 321 without being screened.

[0025] In one embodiment of the present invention, the screening mechanism 3 further includes a rotating frame 33, and two A support shafts 34 are rotatably mounted on the inner side wall of the rotating frame 33, and the axial direction of the A support shaft 34 is the same as the length direction of the sorting plate 321, and one end of the two A support shafts 34 is respectively fixedly connected to the supporting frame 31, and one end of one A support shaft 34 away from the supporting frame 31 is connected to an A rotating driving member 35 for driving it to rotate around its own axis, and the A rotating driving member 35 is a motor or a rotating cylinder, and the A rotating driving member 35 is fixedly mounted on the rotating frame 33, and the output shaft end of the A rotating driving member 35 is fixedly connected to the A support shaft 34; Two B support shafts 36 are fixedly mounted on the rotating frame 33, the axial direction of the B support shaft 36 is perpendicular to the axial direction of the A support shaft 34, and the outer side walls of one end of the B support shaft 36 are respectively rotatably connected with the carrier frame 2, and one end of one of the B support shafts 36 away from the carrier frame 31 is connected with a B rotation driving member 37 that drives it to rotate around its own axis, and the B rotation driving member 37 is a motor or a rotary cylinder, and the B rotation driving member 37 is fixedly mounted on the rotating frame 33, and the output shaft end of the B rotation driving member 37 is fixedly connected to the B support shaft 36; The A support shaft 34 is driven to rotate by the A rotary drive member 35, and the rotation of the A support shaft 34 can drive the bearing frame 31 to rotate around the axis of the A support shaft 34, so that the seeds placed in the bearing frame 31 can enter between the two sorting plates 321 for screening; The B support shaft 36 is driven to rotate by the B rotating drive member 37. The rotation of the B support shaft 36 can drive the rotating frame 33 to rotate around the B support shaft 36. When the rotating frame 33 rotates, it drives the supporting frame 31 to rotate around the B support shaft 36. At this time, the seeds located between the two sorting plates 321 can move along the length direction of the two sorting plates 321, thereby avoiding seed accumulation and preventing seeds from being stuck between the two sorting plates 321, which causes small-size seeds to accumulate without being screened.

[0026] In one embodiment of the present invention, the disinfection mechanism 5 includes a guide hopper 51, which is arranged at the bottom of the screening assembly 32, and the outer side surface of the top of the guide hopper 51 is fixedly connected to the carrier frame 2. A disinfection box 52 is arranged at the bottom of the guide hopper 51, and the disinfection box 52 is filled with a disinfectant for disinfecting seeds. The bottom of the disinfection box 52 is connected to a conveying drive assembly for driving it to move along the length direction of the frame 1; In one embodiment of the present invention, the conveying drive assembly includes a slider 53, the upper surface of the slider 53 is fixedly connected to the disinfection box 52, the bottom of the slider 53 is slidably connected to the frame 1, the inner wall of the slider 53 is threadedly connected with a screw 54, the outer walls of both ends of the screw 54 are respectively rotatably connected to the frame 1, one end of the screw 54 is connected to a C rotating drive member 55 that drives it to rotate around its own axis, the C rotating drive member 55 is a motor or a rotary cylinder, the C rotating drive member 55 is fixedly installed on the frame 1, and the output shaft end of the C rotating drive member 55 is fixedly connected to the end of the screw 54; The guide hopper 51 receives the seeds screened by the screening mechanism 3, and drives the screw 54 to rotate through the C rotating drive member 55. When the screw 54 rotates, it can drive the slider 53 to move along the length direction of the frame 1. The movement of the slider 53 drives the disinfection box 52 to move to the bottom of the guide hopper 51, so that the seeds can fall directly into the disinfection box 52, thereby improving the production and cultivation efficiency of seeds.

[0027] In one embodiment of the present invention, a material receiving box 56 is further provided. The material receiving box 56 is fixedly mounted on the slider 53 and can be used to receive seeds that do not meet the particle size requirements.

[0028] The present application sets up a screening component, wherein two sorting plates are arranged in an inverted eight-shaped shape on the projection surface, and the gap between the two sorting plates is adjusted by an adjustment mechanism, thereby realizing the screening of seeds of different particle sizes, which not only avoids the problem of frequent replacement of traditional screens, but also greatly improves the applicability and flexibility of the equipment, and can easily cope with various types of seed screening needs; The setting of the sorting plate effectively reduces the situation of seeds blocking the holes, ensuring the smooth screening process. At the same time, the precise control of the gap between the sorting plates by the adjustment mechanism can ensure that the particle size of the screened seeds is more uniform, thus improving the efficiency and effect of the screening. By integrating a disinfection mechanism at the bottom of the screening mechanism, the screened seeds can directly fall into the disinfection box for disinfection without the need for secondary transportation. This not only simplifies the operating steps, but also significantly improves the efficiency of seed production and cultivation.
