Description

Technical Field

[0001] The utility model relates to the technical field of seed breeding, in particular to a seed breeding and packaging machine. Background Art

[0002] Before breeding, the seeds need to be screened and selected to screen out seeds that do not meet the requirements, including necrotic seeds and seeds whose particle size does not meet the requirements. The necrotic seeds can be separated by flotation, while the particle size selection requires a seed selection and packaging machine for screening. The present scheme specifically involves a seed selection and packaging machine. The existing seed selection and packaging machine uses vibration screening for screening. The vibration process will not only cause a lot of noise, but also reduce the stability of the packaging machine. At the same time, the mesh frame used for screening cannot be replaced, and different seeds have different requirements for the mesh size of the mesh frame, so it is not convenient enough.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 4 As shown, a seed breeding and packaging machine comprises a base plate 1, support rods 2 are fixedly installed at the center positions on both sides of the top of the base plate 1, a bottom bin 3 is arranged at the top of the base plate 1 and between the two support rods 2, three screening bins 4 are movably connected through a rotating shaft between the two support rods 2 and above the bottom bin 3, a discharge port 8 is fixedly welded at the front end of the screening bin 4, a conveyor belt 9 is installed at the bottom end of the discharge port 8, a driving assembly 6 is installed at the front of the top of the base plate 1, and the driving assembly 6 comprises two parallel arranged linkage rods 601, a slide connecting rod 602 is fixedly installed at the bottom end of the linkage rod 601, a pulley 603 is arranged inside the slide connecting rod 602, a crank 604 is installed on the outer side of the pulley 603, and a motor 605 is installed on one side of one of the cranks 604.

[0019] A base 10 arranged opposite to the motor 605 is fixedly installed at the front of the top of the bottom plate 1, and the output shaft of the motor 605 is fixedly connected to one end of one of the cranks 604, and the base of the motor 605 is fixedly connected to the bottom plate 1. The base 10 is movably connected to one end of the other crank 604 through a rotating shaft, the crank 604 is movably connected to the pulley 603 through a rotating shaft, the pulley 603 is slidingly connected to the slide connecting rod 602, and the linkage rod 601 is movably connected to the discharge port 8 through the rotating shaft. When the motor 605 is started, it drives the crank 604 to rotate. During the rotation of the crank 604, it drives the pulley 603 to slide inside the slide connecting rod 602, thereby driving the linkage rod 601 to move up and down, thereby driving the discharge port 8 to move up and down, thereby inducing the movement of the screening bin 4 to cooperate with the screening net frame 5 to screen and select seeds.

[0020] A screening mesh frame 5 is installed on the back side near the bottom of the screening bin 4, and frame slots 11 are provided on the inner walls on both sides of the screening bin 4 near the bottom. The screening mesh frame 5 is connected to the screening bin 4 through the frame slots 11. The mesh sizes of the three screening mesh frames 5 increase from top to bottom. After the screening mesh frame 5 is pulled out, it is convenient to replace the screening mesh frame 5 with a suitable mesh size as needed.

[0021] A baffle plate 7 is installed near the front end of the bin body on one side that passes through the screening bin 4, and a card slot 12 is opened at the front end of the inner wall of the bin body on the other side that passes through the screening bin 4 and at the top of the card frame slot 11, and the baffle plate 7 is connected to the screening bin 4 through the card slot 12. The baffle plate 7 is used to isolate and divide the screening bin 4 and the discharge port 8 to prevent seeds that have not completed screening from falling onto the conveyor belt 9 through the discharge port 8.

[0022] The frame of the conveyor belt 9 is fixedly connected to the discharge port 8, and the lengths of the three conveyor belts 9 decrease from top to bottom. The screened seeds are conveyed by the conveyor belt 9, and the length difference of the three conveyor belts 9 is used to facilitate the packaging of the seeds.

[0023] It should be noted that the utility model is a seed selection and packaging machine. When in use, firstly, according to the screening requirements, a screening frame 5 of a suitable mesh number is inserted into the card frame slot 11. During installation, the mesh number of the screening frame 5 increases from top to bottom, and then the seeds to be screened are poured into the screening bin 4 on the top layer;

[0024] The motor 605 in the driving assembly 6 is started to drive the crank 604 to rotate. During the rotation of the crank 604, the pulley 603 is driven to slide inside the slide connecting rod 602, thereby driving the linkage rod 601 to move up and down, thereby driving the discharge port 8 to move up and down. During the movement of the discharge port 8, the rotating shaft connected to the support rod 2 is used as a fulcrum to make the screening bin 4 swing up and down around the connection between the support rod 2 and the screening bin 4. During the swinging of the screening bin 4, the seeds keep rolling on the top of the screening mesh frame 5, and the seeds with a particle size smaller than the aperture of the screening mesh frame 5 fall on the next screening mesh frame 5, thereby classifying and screening the seeds and selecting seeds of different particle sizes;

[0025] When the screening is completed, first turn off the motor 605, then pull out the baffle 7, so that the baffle 7 is separated from the screening bin 4, and the three containers are arranged from front to back in sequence under the three conveyor belts 9, and then restart the motor 605 to drive the discharge port 8 to move to the lowest position, so that the seeds in the screening bin 4 roll to the top of the conveyor belt 9, and then use the conveyor belt 9 to convey the seeds to the container to complete the packaging.
