[0002] my country is a major crop planting, production and consumption country. Crops play a vital role in the national food consumption structure. Seeds are closely related to human life. With the continuous improvement of living standards, people's demand for crop quality and safety requirements are increasing. The quality of crop seeds is of great significance to the planting and production of crops. When sorting corn, an automatic sorting device is needed.

[0003] However, traditional corn screening devices mostly use mesh plates and vibration motors for vibration sorting. The mesh plates are flat, and when corn kernels are directly poured in, the corn kernels are not easy to disperse evenly, which affects the sorting efficiency. At the same time, one end of the corn is conical, which is easy to clog the mesh holes of the mesh plate. Utility Model Content

[0004] The utility model aims to provide an automatic seed sorting device. The grid plate is in a plane shape, corn grains are not easy to be evenly dispersed, and the conical end of the corn is easy to block the grid plate.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic seed sorting device, comprising a shell, a sorting mechanism connected to the shell, the sorting mechanism comprising a fixed frame, a fixed frame is arranged inside the shell, a spring is installed between the fixed frame and the shell, a vibration motor is installed on the fixed frame, an inclined screening plate is installed on the top of the fixed frame, the screening plate is corrugated, a plurality of mesh ports are arranged at the bottom of the corrugated groove of the screening plate, and an inclined residual material plate is arranged on the shell below the screening plate;

[0006] The fixed frame is connected to an ejection mechanism, and the ejection mechanism includes a control rod. The fixed frame is provided with a control rod, and a sliding rod is installed on the fixed frame. The control rod is slidably connected to the sliding rod, and the residual material plate is slidably connected to the fixed frame.

The pair of connecting rods are respectively fixed at two ends of the control rod. A second motor is installed on the fixed frame, and a driving disk is installed on the output end of the second motor. A control shaft slidably connected to the control rod is installed on the driving disk.

[0007] As a preferred technical solution of the utility model, the mesh opening is waist-groove-shaped, and a plurality of the mesh openings are arranged in a linear matrix, thereby facilitating the leakage of unqualified corn kernels and sand and gravel.

[0008] As a preferred technical solution of the utility model, the screening plate is parallel to the residual material plate, and the control rod is parallel to the screening plate, thereby ensuring that the top rod can be aligned with the mesh opening and can lift up the blocked corn kernels.

[0009] As a preferred technical solution of the utility model, one end of the push rod close to the screen plate is serrated, and the serrated protrusion end of the screen plate is used to shield the mesh opening, thereby preventing the push rod from pressing corn kernels and sand and gravel.

[0010] As a preferred technical solution of the utility model, a first fence is provided at the inclined top end of the screening plate, and a second fence is provided at the inclined top end of the residual material plate. The second fence is serrated and protrudes, thereby preventing the sorted corn from falling elsewhere.

[0011] As a preferred technical solution of the utility model, a first material trough is installed at the inclined end of the outer shell located on the screening plate, and a second material trough is installed at the inclined end of the outer shell located on the residual material plate. The first material trough and the second material trough are inclined, and the inclination directions of the first material trough and the second material trough are opposite, so as to facilitate the collection of the sorted corn and sand and gravel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides a screening plate and a vibration motor. The corn is poured onto the screening plate. The screening plate is corrugated, so that the corn kernels can be evenly scattered on the corrugated groove. The vibration motor vibrates, and smaller corn kernels or sand and gravel will fall into the mesh mouth under shaking, and then enter the residual material plate. The screening plate and the residual material plate are inclined in parallel, so that the screened corn slides out from the first material trough and the second material trough respectively, so as to facilitate the collection of the sorted corn. The corrugated screening plate can not only disperse the corn evenly, but also promote the corn to slide above the mesh mouth, thereby promoting the corn sorting.

[0014] 2. The utility model sets a push rod, a driving disk and a control shaft. During the corn sorting process, the second motor works, and the second motor drives the driving disk and the control shaft to rotate. The control shaft is eccentric, thereby driving the control rod to move. The control rod is limited by the sliding rod, and the control rod slides up and down, thereby driving the residual material plate and the push rod to move up and down. The push rod can cover the mesh mouth at regular intervals, so that when the tip of the qualified corn blocks the mesh mouth, the push rod can lift it up, thereby preventing the blocked corn from affecting the sorting efficiency.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The fixing frame 25 is arranged inside the shell 1, a spring 26 is installed between the fixing frame 25 and the shell 1, a vibration motor 27 is installed on the fixing frame 25, and an inclined screening plate 24 is installed on the top of the fixing frame 25. The screening plate 24 is in a corrugated shape, so that corns can be gathered to the bottom. A plurality of mesh openings 21 are arranged at the bottom of the corrugated groove of the screening plate 24, and the mesh openings 21 are in a waist groove shape. A plurality of mesh openings 21 are arranged in a linear matrix, so as to facilitate the sorting out of unqualified corn and gravel. The outer shell 1 is provided with an inclined residual material plate 28 below the screening plate 24 for receiving the sorted corn and gravel. The screening plate 24 is parallel to the residual material plate 28, and the control rod 31 is parallel to the screening plate 24. A first fence 4 is provided at the inclined top end of the screening plate 24 to prevent corn from leaking out from the top. The outer shell 1 is provided with a first material trough 22 at the inclined end of the screening plate 24, so as to facilitate the collection of qualified corn.

[0025] During specific use, the corn to be sorted is poured onto the screening plate 24, which is corrugated, so that the corn kernels can be evenly scattered into the corrugated grooves. The vibration motor 27 vibrates, thereby driving the fixing frame 25 to vibrate. The spring 26 plays a shock-absorbing role to prevent the shell 1 from shaking violently. Smaller corn kernels or sand and gravel will fall into the mesh port 21 under the shaking, and then enter the residual material plate 28. The screening plate 24 and the residual material plate 28 are inclined in parallel, so that the screened corn slides out from the first material trough 22 and the second material trough 23 respectively, so as to facilitate the collection of the sorted corn. The corrugated screening plate 24 can not only disperse the corn evenly, but also promote the corn to slide above the mesh port 21, thereby promoting the corn sorting.

[0026] Embodiment 2:

[0027] On the basis of the first embodiment, Figure 4 and Figure 5As shown, the fixed frame 25 is connected with a push-out mechanism 3, and the push-out mechanism 3 includes a control rod 31.

The end of the top rod 33 close to the screening plate 24 is serrated. The serrated protrusion end of the screening plate 24 is used to cover the mesh opening 21, so as to facilitate the lifting of the blocked corn, thereby ensuring the corn sorting efficiency. A pair of connecting rods 32 are installed between the plurality of top rods 33, and the pair of connecting rods 32 are respectively fixed to the control rod At both ends of 31, a second motor 34 is installed on the fixing frame 25, a driving disk 35 is installed on the output end of the second motor 34, and a control shaft 36 slidably connected to the control rod 31 is installed on the driving disk 35. A second fence 5 is provided at the inclined top end of the residual material plate 28, and the second fence 5 is serrated to prevent unqualified corn and sand and gravel from leaking out from the top of the residual material plate 28. A second trough 23 is installed at the inclined end of the residual material plate 28 of the outer shell 1, so as to facilitate the collection of unqualified corn and sand and gravel. The first trough 22 and the second trough 23 are inclined, and the first trough 22 and the second trough 23 are inclined in opposite directions, so as to facilitate the collection of sorted corn.

[0028] During specific use, during the corn sorting process, the second motor 34 works, and the second motor 34 drives the driving disk 35 and the control shaft 36 to rotate. The control shaft 36 is eccentric, thereby driving the control rod 31 to move. Under the limit of the sliding rod 37, the control rod 31 slides up and down, thereby driving the residual material plate 28 and the push rod 33 to move up and down. The push rod 33 can cover the mesh opening 21 at regular intervals, so that when the qualified corn tip blocks the mesh opening 21, the push rod 33 can lift it up, thereby preventing the blocked corn from affecting the sorting efficiency.
