Detailed Description

In order to make the objects and technical solutions of the present utility model more apparent, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

The utility model provides a grain seed singulation vibrating device which is used for achieving the singulation of a large amount of grain seeds in a stacked state. As shown in fig. 1, the vibration module mainly comprises a circular vibration module 1 and a direct vibration module 2.

The circular vibration module 1 comprises a circular vibration base 11 and a circular vibration disc 12, wherein the circular vibration disc 12 is arranged on the circular vibration base 11, the circular vibration base 11 is provided with a circular vibration pulse electromagnet, and the circular vibration disc 12 can vibrate up and down along the axial direction and swing back and forth with the axial direction as the center. The inner side wall of the circular vibration plate 12 is provided with a first guide rail 14 which ascends spirally, and the initial end of the first guide rail 14 is positioned at the middle lower part of the circular vibration plate 12 so as to be capable of receiving and leading in a plurality of cereal seeds. The end of the first guide rail 14 is out of the circular vibration plate 12, and the width of the end is in the particle size range of single grain seeds, so that the grain seeds are in a single grain state in the vibration process and out of the circular vibration module 1.

The direct vibration module 2 comprises a direct vibration base 21, a second guide rail 22 and a direct vibration support 23, wherein the direct vibration base 21 is fixed on the direct vibration support 23, the second guide rail 22 is fixed on the direct vibration base 21, the direct vibration base 21 is provided with a direct vibration pulse electromagnet, and vibration of the second guide rail 22 can be caused to vibrate up and down along the axial direction and swing along the direction of the second guide rail 22. Wherein the width of the second rail 22 is in the single grain seed size range so that the seeds pass through, it is apparent that the beginning of the second rail 22 terminates at the end of the first rail 14.

According to the above structure of the present utility model, more cereal seeds are first placed in the circular vibration plate 12, the circular vibration pulse electromagnet in the circular vibration base 11 is started, and the circular vibration plate 12 is driven to vibrate up and down and to swing reciprocally, the cereal seeds are mutually extruded during the vibration and swing, and one or more cereal seeds are finally brought into the starting end of the first guide rail 14 and spirally go up along the first guide rail 14 during the vibration and swing. Due to the end width limitation of the first rail 14, only single grain seeds are eventually fed out of the circular vibrating tray 12 into the second rail 22. Then, the direct-vibration pulse electromagnet in the direct-vibration base 21 is started, the vibration of the direct-vibration pulse electromagnet drives the second guide rail 22 to vibrate up and down and swing reciprocally, and single grain seeds are slowly sent out in the vibration and swing and are accepted by subsequent equipment, so that grain seeds are single-grained. The utility model adopts the modes of rotary conveying and linear conveying in vibration to realize single grain feeding and blanking classification of seeds, and can provide basic support for improving seed sorting accuracy.

The particle size range refers to the average particle size of a typical single grain seed, and can be appropriately enlarged, but generally should not exceed twice the average particle size of a single grain seed.

In one embodiment of the present utility model, the width of the first rail 14 decreases as the height increases, and the sides of the first rail 14 and the second rail 22 are each provided with a guard edge, the height of which is higher than the grain size of the individual grain seeds.

In this embodiment, the width of the first guide rail 14 gradually decreases along with the height, so that the grain seeds gradually decrease in number on the rail, a large amount of accumulation and blockage are avoided, and the seeds to be sorted move to the outlet in a single granulating state in the vibration process. The arrangement of the protective edge can prevent grain seeds from being thrown out in the vibration. Illustratively, the height of the guard edge is no greater than twice the grain size of the individual grain seed. Too high a guard edge can not effectively throw out redundant seeds by vibration when the seeds are blocked, but can throw out the upper cereal seeds in vibration when the seeds are blocked when the particle size of the cereal seeds is not more than twice that of the single cereal seeds. The width of the second rail 22 maintains the seeds in a relatively uniform posture, forming equally spaced and fast seed streams. The spiral design employed for the first rail 14 reduces friction and material costs.

The power output parameters can be adjusted according to the specific types, the number and the like of the cereal seeds. In fig. 1, a circular vibration control box 31 and a direct vibration control box 32 are shown, which are respectively used for outputting control signals and adjusting vibration parameters. The circular vibration control box 31 and the direct vibration control box 32 jointly form the control box 3 of the utility model, the circular vibration control box 31 regulates and controls the circular vibration base 11, the direct vibration control box 32 regulates and controls the direct vibration base 21, and the vibration frequency is regulated according to different grain seeds, so that the speed of seed single grain and seed flow is controlled.
