For example, when the separation plate is swinging and screening, too many seeds may block the required seeds from passing through the separation plate normally, thereby reducing the accuracy of sampling. At the same time, when the collection plate is moved out to take the material, if the discharge flow is uncontrollable, the amount of seeds on the collection plate may exceed the expected amount, causing inconvenience in taking the material or the need for frequent operation of the collection plate.

[0026] Below, combining the drawings and specific implementation, the utility model is further described, and it is explained that under the prerequisite of not conflict, the following described each embodiment between or each technical feature between can form new embodiment arbitrarily.

[0027] Embodiment:

[0028] Please combine Figures 1-5The grain seed detection sample divider of the embodiment comprises a treatment box 1, the upper surface of the treatment box 1 is fixedly connected with a feeding bin 2, the upper surface of the treatment box 1 is provided with a top groove 3, the inside of the top groove 3 is slidably connected with a movable baffle 4, the upper surface of the treatment box 1 is provided with a discharging groove 5, the surface of the movable baffle 4 is fixedly connected with an electric push rod 6, the inner wall of the treatment box 1 is fixedly connected with an amplitude spring column 7, the surface of the amplitude spring column 7 is fixedly connected with a separation net one 8, the lower surface of the separation net one 8 is fixedly connected with a vibration motor 9, the surface of the separation net one 8 is fixedly connected with a transmission rod one 10, the bottom end of the transmission rod one 10 is fixedly connected with a separation net two 11, and the grain seeds enter the treatment box 1 from the feeding bin 2. A person operates the electric push rod 6, and the electric push rod 6 drives the movable baffle 4 to slide in the top groove 3. The position change of the movable baffle 4 changes the shielding area of the discharging groove 5, so as to control the seed discharging flow. At the same time, the vibration motor 9 is started, drives the separation net one 8 to vibrate on the amplitude spring column 7, the seeds are subjected to primary sampling through the separation net one 8, and the separation net one 8 drives the separation net two 11 to perform secondary sampling through the transmission rod one 10. Since the aperture of the separation net one 8 is larger than that of the separation net two 11, the sampling of seeds with different particle sizes is realized, and the vibration process can also prevent the seeds from being blocked on the separation net one 8 and the separation net two 11.

[0029] The movable baffle 4 is located below the discharging groove 5, the electric push rod 6 is fixedly connected to the inner wall of the top groove 3, and the telescopic action of the electric push rod 6 can accurately drive the movable baffle 4 to shield and control the discharging groove 5. This structure design makes the movement of the movable baffle 4 more accurately associated with the opening and closing of the discharging groove 5, so as to accurately control the seed discharging flow.

[0030] The surface of the separation net two 11 is fixedly connected with a transmission rod two 12, the bottom end of the transmission rod two 12 is fixedly connected with a separation net three 13, the transmission rod two 12 on the separation net two 11 transmits the vibration of the separation net two 11 to the separation net three 13, so as to realize the vibration of the separation net three 13. In this way, after the seeds pass through the separation net two 11, further sampling operation can be performed on the separation net three 13, and the level of sampling is increased.

[0031] The amplitude spring column 7 is respectively fixedly connected to the lower surfaces of the separation net two 11 and the separation net three 13. When the vibration motor 9 drives the separation net one 8 to vibrate, the vibration is transmitted to the separation net two 11 and the separation net three 13 through the transmission rod one 10 and the transmission rod two 12, etc. The amplitude spring column 7 provides elastic support for the vibration of the separation net two 11 and the separation net three 13, so that the vibration is more stable and uniform, which is beneficial to the sampling operation of the seeds on the separation net.

[0032] The inner wall of the processing box 1 is fixedly connected with a flow guide plate 14, which guides the falling direction of the seeds after the seeds fall from the feeding groove 5, so that the seeds can fall more orderly on the separating net 8, thereby avoiding the falling of the seeds being too scattered and affecting the sample separation effect.

[0033] The flow guide plate 14 is located below the feeding groove 5.

[0034] Both sides of the surface of the processing box 1 are hingedly connected with sealed box doors 15.

[0035] The implementation principle of the sample separator for grain seed detection in the embodiment is as follows: first, according to the actual sample separation requirement, the electric push rod 6 is started, the electric push rod 6 is extended or retracted, and the movable baffle 4 is driven to slide in the top groove 3, if a larger seed feeding flow is required, the electric push rod 6 pushes the movable baffle 4, the shielding area of the movable baffle 4 on the feeding groove 5 is reduced, and more seeds can pass through the feeding groove 5 and enter the processing box 1, if a smaller seed feeding flow is required, the electric push rod 6 pulls the movable baffle 4, the shielding area of the movable baffle 4 on the feeding groove 5 is increased, thereby reducing the amount of seeds passing through the feeding groove 5, then the vibration motor 9 is started, the vibration motor 9 drives the separating net 8 to vibrate on the amplitude spring column 7, the grain seeds enter the processing box 1 from the feeding bin 2, after the flow adjustment of the feeding groove 5, the seeds fall on the separating net 8 under the guidance of the flow guide plate 14, due to the vibration of the separating net 8, the seeds start to be initially separated, the seeds with smaller particle size fall through the mesh holes of the separating net 8, the separating net 8 drives the separating net 11 to vibrate through the transmission rod 10, and secondary sample separation is performed, at this time, part of the seeds with smaller particle size in the larger particle size seeds that do not pass through the separating net 8 fall through the mesh holes of the separating net 11, the separating net 11 drives the separating net 13 to vibrate through the transmission rod 12, and third sample separation is performed, and seeds with smaller particle size are further screened out, when the sample separation work is completed or equipment maintenance is required, the sealed box door 15 is opened, and the seeds are taken out.

[0036] The above embodiment is only a preferred embodiment of the present application, and cannot be used to limit the scope of protection of the present application, and any non-substantial changes and replacements made by those skilled in the art on the basis of the present application all belong to the scope of protection of the present application.
