DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0025] Combination Figures 1-4 As shown in the figure, an automatic particle counter, comprising:

[0026] The photoelectric particle counter 1 is used to count the sesame by the internal photoelectric sensor, so as to ensure the uniformity of the quality of the packing;

[0027] The vibrating screen 2 uses vibration to continuously convey the sesame in order to cooperate with the photoelectric particle counter 1 to count;

[0028] The sorting assembly 3 is arranged on the top of the photoelectric particle counter 1 and directly above the vibrating screen 2, which is mainly used for filtering and grading the raw materials, and then discharging them into the vibrating screen 2 to cooperate with the photoelectric particle counter 1 for counting and packaging.

[0029] Specifically, in this embodiment, since the sesame is affected by sunlight, moisture and soil during the collection process, the size of the sesame particles is different, and if the sesame is not graded, it is easy to cause misjudgment of the photoelectric sensor, thereby affecting the precision of the photoelectric particle counter 1. Therefore, a plurality of feeding ports should be arranged on the top of the photoelectric particle counter 1, and a small vibrating screen 2 is arranged on one side of each feeding port. The vibrating screen 2 adopts a circular structure, so that the sesame can be queued and transported towards the feeding port along the conveying structure on the vibrating screen 2 after entering the vibrating screen 2, thereby effectively cooperating with the photoelectric sensor to count the sesame particles, so as to control the precision of the packaging.

[0030] On the basis of the above structure, in order to avoid the influence of the vibrating screen 2 on the whole device, a shock isolation seat 4 should be arranged at the bottom of each vibrating screen 2. The shock isolation seat 4 includes an upper mounting plate and a lower mounting plate. The top surface of the upper mounting plate is fixedly connected with the vibrating screen 2 by bolts, and the lower mounting plate is fixedly connected with the top surface of the photoelectric particle counter 1 by bolts. A damper is arranged between the upper mounting plate and the lower mounting plate. The damper is provided with a plurality of damping rods, so as to absorb the vibration generated by the vibrating screen 2 by contraction and extension of the damping rods, thereby isolating the transmission of the vibration and weakening the influence on the photoelectric particle counter 1.

[0031] The sorting assembly 3 includes a mounting frame 31, a screening box 32 and an air separation box 33.

[0032] The mounting frame 31 is arranged on the top of the photoelectric particle counter 1 and extends upwards, which is a main supporting structure.

[0033] The screening box 32 is fixedly installed on the upper half of the mounting frame 31 by bolts, and uses the screening structure inside to grade the sesame and preliminarily separate the impurities in the sesame.

[0034] The air separation box 33 is fixedly installed on the lower half of the mounting frame 31 by bolts, and uses the air separation structure inside to secondarily screen the sesame, so as to remove the dust, small particle impurities and shriveled sesame in the sesame, thereby further improving the quality of the sorted sesame.

[0035] In the above structure, the inside of the screening box 32 is provided with multiple screens 37, which are rectangular vibrating screens 2, and the vibrating screens 2 are arranged in a whole body inclined manner, and are provided with vibration motors inside, and two vibrating screens 2 adjacent to each other are arranged in opposite directions, and the vibrating screens 2 are arranged from top to bottom, and the screen holes gradually decrease, and the first layer is mainly used to screen out various large impurities in the sesame, such as sesame leaves, sesame rods, etc., and the sesame is gradually separated from the second layer.

[0036] The bottom of the screening box 32 is conical, and is provided with a foreign matter discharge pipe 5 at the bottom, because the fine sand and stones that pass through multiple layers of screens 37 and reach the lowest place are all fine, and are concentrated by the inclined side wall and discharged into the collection box inside through the foreign matter discharge pipe 5, so as to be processed separately later.

[0037] In addition, multiple material guide pipes 34 are arranged on the side wall of the screening box 32, and each material guide pipe 34 is arranged at the bottom end of a screen 37, that is, the material remaining on the surface of the screen 37 is discharged to the outside of the screening box 32 through the material guide pipe 34, and the material guide pipe 34 at the bottom is used to discharge the remaining impurities into the collection box, and the other material guide pipes 34 extend downward and are communicated with the winnowing box 33.

[0038] In the winnowing box 33, the inside space is divided into multiple independent spaces by a partition, and the number of independent spaces is the same as the number of sesame grades, for example, if the sesame is divided into three grades, three independent spaces are provided to separately screen each grade of sesame.

[0039] In addition, a rectangular opening is arranged on one side of the winnowing box 33, and a fan 38 support is movably arranged in the rectangular opening by a sliding groove structure, and multiple fans 38 are arranged on the fan 38 support in an interval, and the number of fans 38 is the same as the number of independent spaces, each fan 38 corresponds to an independent space, and blows air inward.

[0040] Ventilation holes are arranged on the inner wall of the winnowing box 33 away from the fan 38, so that when the fan 38 blows air, the vertical airflow contacts the sesame particles falling downward, and in this process, the quality of the sesame particles is lighter, the small impurities that are not screened clean, and dust are blown to the side away from the sesame particles.

[0041] Two V-shaped storage tanks are arranged at the bottom of the independent space, and the screened sesame particles fall into one of the storage tanks, and the other is used to store empty shell sesame and impurities, the storage tank storing the sesame particles is connected with a discharge pipe 35, and the discharge pipe 35 directly inputs the vibrating screen 2, and the other storage tank is provided with a dust discharge port and a pipe to discharge into the collection box.

[0042] Since in the blowing process, if the sesame is contaminated with dust, it is easy to cause a large amount of dust to be raised, so the inside of the winnowing box 33 can be appropriately equipped with an atomizing spray structure, that is, using atomized water to capture dust, so that it is settled in the storage tank, in order to prevent the influence on the surrounding environment.

[0043] And in the above structure, the sesame is processed in stages, and the size of the sesame is different, and the blowing speed of the fan 38 used is also different, so the fan 38 on the fan 38 support should be set to a corresponding power size, to avoid waste of good products / mixed with defective products due to excessive / inadequate airflow.

[0044] In the above structure, it is also necessary to strictly control the discharge speed of the sesame particles. If the sesame is discharged too fast, the winnowing structure cannot effectively screen the shriveled sesame, so a plurality of adjusting valves 36 need to be provided on the top of the winnowing box 33, each adjusting valve 36 is provided on the top of an independent space, and the top end is in communication with the bottom end of the material guide pipe 34. The adjusting valve 36 can be a ZDLP / JSVB7300 or similar electric valve, and the purpose is to facilitate remote control by the staff.

[0045] In summary, the above structure, the sesame particles can be double-screened by the sorting assembly 3, and then discharged in a graded state and individually into the photoelectric particle counter 1 for packaging. This not only enables the individually packaged sesame particles to be close in size, but also ensures that the photoelectric sensor inside the photoelectric particle counter 1 is easier to detect, effectively improving the accuracy of the entire device in separating the sesame particles.

[0046] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the present application.
