Description

Technical Field

[0001] This utility model belongs to the field of seed selection technology, and in particular relates to a seed selection device for agricultural experiments. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary sector, and the science that studies agriculture is agronomy. The objects of agricultural labor are living plants and animals, and the products obtained are the plants and animals themselves. Agriculture is a fundamental industry that provides support for national economic construction and development.

[0003] In agricultural experiments, in order to cultivate superior crops, it is necessary to screen crop seeds to select high-quality crop seeds. However, in the existing technology, most crop screening is done manually, which has low screening efficiency and reduces the efficiency of agricultural experiments. Therefore, a seed selection device for agricultural experiments is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a seed selection device for agricultural experiments to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a seed selection device for agricultural experiments, comprising a box body. A discharge port 1 and a discharge port 2 are respectively opened on two opposite surfaces of the inner wall of the box body. A screening plate 1 and a screening plate 2 are respectively hinged inside the box body. A guide plate 1 and a guide plate 2 are respectively arranged on two opposite surfaces of the inner wall of the box body. A rotating rod 1 and a rotating rod 2 are respectively rotatably connected inside the box body. An arc-shaped sleeve 1 is arranged on the bottom surface of the guide plate 1. An arc-shaped hollow tube 1 is slidably connected inside the arc-shaped sleeve 1. A spring 1 is arranged on the upper surface of the inner wall of the arc-shaped sleeve 1. An arc-shaped sleeve 2 is arranged on the bottom surface of the guide plate 2. A second arc-shaped hollow tube is slidably connected inside the second tube. A second spring is provided on the upper surface of the inner wall of the second arc-shaped tube. A first servo motor is provided on the back of the box. A first pulley is provided at the front end of the first rotating rod. A second pulley is provided at the front end of the second rotating rod. A belt is fitted around the sides of the first and second pulleys. A collection box is provided inside the box. A striking rod is provided on both the second rotating rod and the side of the rotating rod. A feeding frame is provided on the upper surface of the box. A second servo motor is provided on the back of the feeding frame. A rotating roller is rotatably connected inside the feeding frame. Several stirring blades are provided on the side of the rotating roller.

[0007] Furthermore, the output end of the servo motor is fixedly connected to one end of the rotating roller, the feeding frame is connected to the box body, and several slots are opened on the circumferential sides of the pulley and the belt pulley, and several locking blocks are provided on the inner wall of the belt to match the slots.

[0008] Furthermore, the output end of the servo motor is fixedly connected to the free end of the rotating rod. The rotating rod is located on the right side below the screening plate, and the rotating rod is located on the left side below the screening plate. The bottom surface of the arc-shaped hollow tube is fixedly connected to the right side of the upper surface of the screening plate. The bottom end of the spring is fixedly connected to the bottom surface of the inner wall of the arc-shaped hollow tube. The bottom surface of the arc-shaped hollow tube is fixedly connected to the left side of the upper surface of the screening plate. The bottom end of the spring is fixedly connected to the bottom surface of the inner wall of the arc-shaped hollow tube.

[0009] This utility model has the following beneficial effects:

[0010] This invention involves pouring seeds into a feeding frame, which then enters the sieve for screening. After entering the feeding frame, a servo motor drives a rotating roller, which in turn rotates the agitating blades on the circumferential side, thus stirring the seeds and preventing them from accumulating and clogging. Simultaneously, the servo motor drives a rotating rod, which in turn drives a belt to rotate a second rotating rod. The rotation of both rotating rods simultaneously causes striking rods on the circumferential side to strike the bottom surfaces of screening plates one and two. When the striking rods lift the bottom surfaces of screening plates one and two, springs one and two are compressed; when they are no longer lifted, springs one and two return to their original positions, causing the screening plates to vibrate. This sieving process separates the seeds that have fallen onto the surfaces of screening plates one and two. Screening plate one primarily filters out larger particles than the seeds, while screening plate two primarily filters out shriveled, broken, and small seeds, which then fall into the collection box.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The bottom surfaces of screening plates 12 and 14 are struck respectively. When the striking rod 108 lifts the bottom surfaces of screening plates 12 and 14, springs 132 and 143 are compressed. When the striking rod 108 does not lift the bottom surfaces of screening plates 12 and 14, springs 132 and 143 are reset, causing screening plates 12 and 14 to vibrate. This sieving process is used to separate the seeds that have fallen onto the surfaces of screening plates 12 and 14. Screening plate 12 mainly filters out large particles larger than the seeds, while screening plate 14 mainly filters out shriveled, broken, and small seeds, which then fall into the collection box 106.
