[0002] Wheat seed processing requires multiple processes such as threshing, pre-cleaning, sorting, drying, coating and packaging. After the completion of various processes, a feeding device is required to unload the seeds.

[0007] To further optimize the technical solution, a discharging control mechanism of a vibrating feeding device for wheat seed processing includes a discharging port opened on the front side of the upper part of the carrying bucket; a sealing plate is correspondingly arranged outside the discharging port; the sealing plate is vertically slidably connected to the outer wall of the carrying bucket; the sliding of the sealing plate is controlled by a second telescopic device fixed to the outer wall of the carrying bucket; a screw rod is provided above the carrying bucket along the front-to-back direction; the screw rod is rotatably connected to the carrying bucket; the screw rod is driven by a power motor fixed to the outer wall of the carrying bucket; a push plate is slidably arranged in the left and right directions inside the carrying bucket; the bottom end of the push plate corresponds to abutting against the upper side of the flexible support pad; the push plate is threadedly connected to the adjusting screw rod.

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, a vibrating feeding device for wheat seed processing comprises a carrying bucket 1 arranged along the left-right direction; a flexible supporting pad 2 for carrying wheat seeds is sleeved inside the upper side of the carrying bucket 1; the flexible supporting pad 2 is sealed and fixed to the inner wall of the carrying bucket 1 on all sides; a discharging control mechanism for removing wheat seeds is arranged on the carrying bucket 1; a vibrating scattering mechanism is arranged below the flexible supporting pad 2; a crossbeam 3 is arranged above the carrying bucket 1; the crossbeam 3 is connected to the carrying bucket 1 through a vertically arranged supporting guide rod 4; a mounting plate 5 is horizontally arranged below the crossbeam 3; an auxiliary toggle mechanism is arranged on the mounting plate 5; the mounting plate 5 is slidably connected to the supporting guide rod 4; a first telescope 6 is fixed on the crossbeam 3; the first telescope 6 is connected to the mounting plate 5; the first telescope 6 is used to control the mounting plate 5 to slide along the supporting guide rod 4;

[0023] like Figure 1 As shown, the vibration breaking mechanism includes an ultrasonic vibration generator 7 fixed inside the carrying bucket 1; the space between the flexible support pad 2 and the carrying bucket 1 is filled with water; the ultrasonic vibration generator 7 is immersed in the water; and a plurality of exciting particles 8 are distributed in the water;

[0024] like Figure 2 As shown, the auxiliary toggle mechanism includes a plurality of toggle members arranged from left to right below the mounting plate 5; the toggle members include a first push rod 9 and a second push rod 10 fixedly connected thereto; the second push rod 10 is arranged along the front-to-back direction; the first push rod 9 is connected to a spring telescopic rod 11 arranged along the left-to-right direction; one end of the spring telescopic rod 11 is fixed to the mounting plate 5, and the other end is fixed to the first push rod 9; a vertical support rod 12 is fixed to the lower end of the second push rod 10; an action bar 13 for toggling wheat seeds is connected to the lower end of the support rod 12; a driving member for controlling the left-right movement of the plurality of toggle members is provided on the mounting plate 5.

[0025] The wheat seeds can be transported to the carrying bucket 1 through a conveying device, and the wheat seeds are carried by a flexible support pad 2 (which can be made of materials such as silicone and rubber), and then the ultrasonic vibration generator 7 acts to make the filled water vibrate at a high frequency, and the exciting particles 8 also vibrate in the water. The high-frequency vibration of the water and the vibration of the exciting particles 8 impact the flexible support pad 2, causing the wheat seeds to vibrate as a whole, which is conducive to shaking off the agglomerated wheat seeds. If it is necessary to improve the support of the flexible support pad 2, it is sufficient to add a support point between the flexible support pad 2 and the carrying bucket 1.

[0026] In the above process, the flexible support pad 2 is used to support the seeds. On the one hand, it is beneficial to reduce vibration attenuation. The flexible support pad 2 itself flexibly shakes with vibration, so that the vibration effect can act more effectively on the wheat seeds. On the other hand, the vibration impact of the excitation particles 8 can also be transmitted to various positions of the flexible support pad 2 respectively. The position where the excitation particles 8 transmit the impact to the flexible support pad 2 can accurately act on the wheat seeds at this position. The vibration effect on the wheat seeds here is improved, while the position not impacted by the excitation particles 8 is weaker. This difference in strength will be reflected in the different amplitudes of the wheat seeds at different positions. This method helps to separate the agglomerated parts of the wheat seeds.

[0027] In addition to vibration, in this technical solution, the first telescopic device 6 can be used to drive the mounting plate 5 to move downward along the supporting guide rod 4, so that multiple action bars 13 are inserted into the wheat seeds, and then the first push rod 9 is controlled to move left and right by the driving member, so that the action bar 13 can be driven to move left and right in the wheat seeds, which is further conducive to separating the wheat seeds. The tossing action and the vibration action can complement each other to solve the problem of seed aggregation. The telescopic guidance of the spring telescopic rod 11 can ensure the stable movement of the first push rod 9.

[0028] It can be said that the vibration generated by the ultrasonic vibration generator 7 on the water makes the wheat seeds "vibrate as a whole", while the vibration impact of the exciting particles 8 can "vibrate separately" on different parts of the wheat seeds. In addition, the action bar 13 is inserted into the wheat seeds to stir them, and the control of the insertion depth can achieve "layer-by-layer stirring" of the wheat seeds. The combination of these effects can perfectly solve the problem of local agglomeration of wheat seeds.

[0029] like Figure 3 As shown, the discharge control mechanism includes a discharge port 14 opened on the front side of the upper part of the carrying bucket 1; a sealing plate 15 is correspondingly arranged outside the discharge port 14; the sealing plate 15 is connected to the outer wall of the carrying bucket 1 along the vertical sliding direction; the sealing plate 15 is controlled to slide by a second telescopic device 16 fixed on the outer wall of the carrying bucket 1; a screw rod 17 is provided above the carrying bucket 1 along the front-to-back direction; the screw rod 17 is rotatably connected to the carrying bucket 1; the screw rod 17 is driven by a power motor 18 fixed on the outer wall of the carrying bucket 1; a push plate 19 is slidably arranged in the carrying bucket 1 along the left-right direction; the bottom end of the push plate 19 corresponds to abutting against the upper side of the flexible support pad 2; the push plate 19 is threadedly connected to the adjusting screw rod 17.

[0030] After the wheat seeds have solved the local agglomeration problem through this device, the second telescopic device 16 drives the sealing plate 15 to release the blockage of the discharge port 14, and then the power motor 18 drives the screw rod 17 to rotate, and the push plate 19 can push the seeds on the flexible support pad 2 through the discharge port 14, which is convenient for the subsequent process.

[0031] The excitation particles 8 are spherical hollow structures. The spherical structure of the excitation particles 8 can reduce the wear on the flexible support pad 2 when impacting the flexible support pad 2, and the hollow structure can reduce the weight to ensure that the flexible support pad 2 can be fully contacted and impacted after vibration.

[0032] like Figure 2 , Figure 4 As shown, the driving member includes a driving motor 20 fixed to the lower end of the mounting plate 5; the output end of the driving motor 20 is coaxially connected to an output shaft 21 along the left-right direction; the output shaft 21 is rotatably connected to the bottom of the mounting plate 5; an eccentric ball wheel 22 corresponding to the first push rod 9 is sleeved and fixed on the output shaft 21; the first push rod 9 is inclined in the horizontal position, and the end opposite to the eccentric ball wheel 22 is an inclined structure; the eccentric ball wheel 22 is used to push the first push rod 9 to move.

[0033] The end of the first push rod 9 opposite to the eccentric ball wheel 22 is an inclined surface structure, so that when the eccentric ball wheel 22 rotates, the eccentric ball wheel 22 can make a smoother contact with the first push rod 9. The setting of the eccentric ball wheel 22 can drive the eccentric ball wheel 22 to rotate through the output shaft 21, and push the first push rod 9 through the raised end of the eccentric ball wheel 22, and then through the elastic rebound effect of the spring telescopic rod 11, when the eccentric ball wheel 22 rotates to the raised end and begins to leave the first push rod 9, the first push rod 9 is pulled back, thereby realizing the reciprocating movement of the first push rod 9, that is, realizing the reciprocating movement of the action bar 13 on the wheat seeds. The first push rod 9 is tilted in the horizontal position to increase the distance that the first push rod 9 is pushed, that is, to expand the range of movement of the action bar 13 on the wheat seeds.

[0034] like Figure 5 As shown, a plurality of diverting strips 23 are connected to the action strip 13 and are arranged obliquely in the horizontal direction. The arrangement of the diverting strips 23 can further expand the range of wheat seeds that can be moved, and because the orientation of the diverting strips 23 is different from that of the action strips 13, the seeds can be moved from different directions, thereby improving the diverting and dispersing effect of the seeds.

[0035] like Figure 5 As shown, the support rod 12, the action bar 13 and the material-moving bar 23 are all hollow structures; a plurality of telescopic air hoods 24 are connected to the material-moving bar 23; a blowing and suction air pump 25 is fixed on the moving member; the blowing and suction port of the blowing and suction air pump 25 blows or sucks air into the telescopic air hood 24 through the conduit 26.

[0036] The function of the blowing and suction air pump 25 is to blow and suck air back and forth into the telescopic air hood 24. Through the reciprocating expansion and contraction of the telescopic air hood 24 in the wheat seeds, it can produce an impact and striking effect on the seeds locally, which, combined with the stirring process and the vibration process, can further improve the efficiency of breaking up the seeds.

[0037] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
