Description

Technical Field

[0001] This utility model relates to the field of seed selection machine technology, specifically a seed selection machine for agricultural scientific research experiments. Background Technology

[0002] Agricultural research experiments are a core link in promoting agricultural technological progress. They aim to solve practical problems in agricultural production through scientific methods, improve crop yield, quality, and agricultural production efficiency. Seed sorting machines for agricultural research experiments are mechanical devices used in agricultural research to sort and grade seeds. Based on the aerodynamic characteristics of seeds and impurities, airflow is used to separate lighter impurities such as shriveled grains, husks, and grass seeds from the seeds. By adjusting the speed and direction of the airflow, the impurities are sucked into a dust collector and discharged, while plump seeds pass through an air sieve and enter the next process.

[0003] Chinese utility model patent CN219899106U discloses a seed selection machine for agricultural scientific research experiments, including a screening box. A feeding hopper is fixedly connected to the top of the screening box. A first screening mechanism is installed inside the screening box, and a second screening mechanism is installed below the first screening mechanism. A quantity control mechanism is installed inside the feeding hopper to ensure uniform feeding. The quantity control mechanism includes two baffles. The feeding speed is controlled by adjusting the inclination angle of the baffles to ensure uniform feeding and avoid excessive feeding at once, which would affect the screening effect. A worm gear drives a worm wheel to rotate the rotating shaft. The self-locking property of the worm wheel and the worm gear prevents changes in the baffle inclination angle after adjustment. Glass windows are provided on the front of both the screening box and the feeding hopper for easy observation of the internal conditions and timely detection of malfunctions.

[0004] However, during use, due to the large gap between the elastic reflector and the second collection box, even if the angle of the elastic reflector is adjusted, the gap between the two cannot be changed. This easily leads to some seeds not being accurately collected by the second collection box, requiring additional cleaning by staff, which affects work efficiency and cannot meet production needs. Therefore, a seed selection machine for agricultural scientific research experiments is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a seed sorting machine for agricultural scientific research experiments. It has the advantage of accurately collecting seeds and solves the problem that in existing seed sorting machines, there is a large gap between the elastic reflector and the second collection box. Even if the angle of the elastic reflector is adjusted, the gap between the two cannot be changed, which easily leads to some seeds not being accurately collected by the second collection box, requiring additional cleaning by staff and affecting work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seed selection machine for agricultural scientific research experiments, including a base and an air separator box fixedly connected to the top of the base, a support platform fixedly connected to the top of the base, and a screening mechanism capable of secondary screening of seeds provided on the top of the support platform;

[0007] The screening mechanism includes a screening plate slidably connected to the top of a support platform. A drive motor is fixedly connected to the upper surface of the support platform. A rotating plate is fixedly connected to the output shaft of the drive motor. A connecting rod is rotatably connected between the rotating plate and the screening plate. A screening screen is fixedly connected to the inner bottom wall of the screening plate. A collection box extending to the front of the support platform is slidably connected inside the support platform.

[0008] Furthermore, the upper surface of the support platform is provided with an opening that communicates with the collection box, and the bottom of the air separator is fixedly connected with a discharge pipe that communicates with the screening plate.

[0009] Furthermore, the bottom of the screening plate is fixedly connected to a positioning roller extending into the support platform, and the upper surface of the support platform is provided with a positioning groove that matches the positioning roller.

[0010] Furthermore, a mounting cover is fixedly connected to one side of the air separator, and a fan is installed inside the mounting cover.

[0011] Furthermore, the air separator box has a through hole that communicates with the mounting cover, and a dustproof net is fixedly connected to the side of the mounting cover away from the air separator box.

[0012] Furthermore, a guide plate is fixedly connected to the inner wall of the air classifier, and both the front and back sides of the guide plate are fixedly connected to the inner wall of the air classifier. A feed hopper communicating with the interior of the air classifier is fixedly connected to the top of the air classifier.

[0013] Furthermore, a separation box is fixedly connected to the top of the base, an air pump is fixedly connected to the side of the separation box away from the air classifier, a sealing cover is installed on the top of the separation box, a separation cylinder extending into the separation box is fixedly connected to the bottom of the sealing cover, and a connecting pipe connecting the separation cylinder and the air classifier is fixedly connected to the top of the sealing cover.

[0014] Furthermore, the end of the connecting pipe away from the separation cylinder is located on the upper surface of the guide plate, and a support frame that can support the separation cylinder is fixedly connected inside the separation box.

[0015] Compared with the prior art, this utility model provides a seed selection machine for agricultural scientific research experiments, which has the following beneficial effects:

[0016] 1. This seed sorting machine for agricultural research experiments uses a drive motor to rotate a rotating plate. A connecting rod, in conjunction with the rotating plate, drives a screening plate to move back and forth, facilitating a secondary screening of the wind-separated seeds and improving the screening quality. Furthermore, because the wind-separation box is located directly above the screening plate, the seeds inside the box are precisely transported to the screening plate, preventing seeds from scattering everywhere.

[0017] 2. This seed sorting machine for agricultural research experiments, equipped with a fan, can perform air sorting on seeds entering the air sorting box. Simultaneously, by incorporating an air extractor and a separator, it can collect and process the impurities separated by air. Furthermore, the suction reduces the re-mixing of impurities with seeds, further improving air sorting efficiency. This solves the problem in existing seed sorting machines where a large gap exists between the elastic reflector and the second collection box. Even with angle adjustments to the elastic reflector, this gap cannot be eliminated, leading to some seeds not being accurately collected by the second collection box, requiring additional cleaning by staff and impacting work efficiency.

[0023] 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.

[0024] Please see Figures 1 to 4 This embodiment of a seed selection machine for agricultural scientific research experiments includes a base 1 and an air separator 2 fixedly connected to the top of the base 1. A support platform 3 is fixedly connected to the top of the base 1. A screening mechanism capable of secondary screening of seeds is provided on the top of the support platform 3. The screening mechanism includes a screening plate 4 slidably connected to the top of the support platform 3. A drive motor 5 is fixedly connected to the upper surface of the support platform 3. A rotating plate 6 is fixedly connected to the output shaft of the drive motor 5. A connecting rod 7 is rotatably connected between the rotating plate 6 and the screening plate 4. A sieve screen 8 is fixedly connected to the inner bottom wall of the screening plate 4. A collection box 9 extending to the front of the support platform 3 is slidably connected inside the support platform 3.

[0025] Specifically, the upper surface of the support platform 3 is provided with an opening that communicates with the collection box 9, the bottom of the air separator 2 is fixedly connected with a feeding pipe that communicates with the screening plate 4, the bottom of the screening plate 4 is fixedly connected with a positioning roller 10 that extends into the support platform 3, and the upper surface of the support platform 3 is provided with a positioning groove 11 that matches the positioning roller 10.

[0026] It should be noted that the side of the screening plate 4 away from the drive motor 5 is open, which facilitates the discharge of seeds on the screening plate 4. By setting the drive motor 5 to drive the rotating plate 6 to rotate, and by setting the connecting rod 7, the screening plate 4 can be moved back and forth left and right in cooperation with the rotating plate 6, which facilitates the secondary screening of the seeds after wind separation and improves the screening quality of the seeds.

[0027] Please see Figure 1 In this embodiment, a mounting cover 12 is fixedly connected to one side of the air classifier box 2. A fan 13 is provided inside the mounting cover 12. A through hole communicating with the mounting cover 12 is opened inside the air classifier box 2. A dustproof net is fixedly connected to the side of the mounting cover 12 away from the air classifier box 2.

[0028] Specifically, a guide plate 14 is fixedly connected to the inner wall of the air classifier 2. The front and back of the guide plate 14 are fixedly connected to the inner wall of the air classifier 2. A feed hopper 15 that communicates with the interior of the air classifier 2 is fixedly connected to the top of the air classifier 2.

[0029] It should be noted that the feed hopper 15 is located on the top of the air classifier 2 near the mounting cover 12, which allows the seeds entering the air classifier 2 to be as close as possible to the fan 13, thereby achieving a good air classification effect.

[0030] Please see Figure 1 In this embodiment, a separation box 16 is fixedly connected to the top of the base 1, an air pump 17 is fixedly connected to the side of the separation box 16 away from the air separator 2, a sealing cover 18 is installed on the top of the separation box 16, a separation cylinder 19 extending into the separation box 16 is fixedly connected to the bottom of the sealing cover 18, and a connecting pipe 20 that connects the separation cylinder 19 and the air separator 2 is fixedly connected to the top of the sealing cover 18.

[0031] Specifically, the end of the connecting pipe 20 away from the separating cylinder 19 is located on the upper surface of the guide plate 14, and the inside of the separating box 16 is fixedly connected to a support frame 21 that can support the separating cylinder 19.

[0032] It should be noted that the separation cylinder 19 and the sealing cover plate 18 are connected by a snap-fit. When the staff removes the sealing cover plate 18, the separation cylinder 19 can be separated from the sealing cover plate 18, thereby cleaning the impurities inside the separation cylinder 19.

[0033] The working principle of the above embodiments is as follows:

[0034] First, the staff slowly pours the seeds into the air separator 2 through the feed hopper 15, and at the same time starts the fan 13 and the vacuum pump 17, so that the impurities in the seeds fall onto the guide plate 14 under the action of air pressure and are collected into the separator 19. Then, the air-separated seeds enter the screening plate 4. At this time, the drive motor 5 is started to drive the screening plate 4 to reciprocate, thereby performing a second screening process on the seeds. The screened seeds are collected by the collection box 9.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
