Description

Technical Field

[0001] This application relates to the field of cashew nut sorting equipment, and particularly to a feeding device for the front end of cashew nut sorting. Background Art

[0002] With the development of the economy, people's incomes are continuously increasing, and the pursuit of material living standards is also constantly rising. By screening cashew nuts of different economic values, users can accurately purchase different grades of cashew nuts they need. However, for the screening of fruits smaller than the average size and those with half-damaged fruits, the current technology in this area is still relatively crude and backward, and the performance of the small fruit removal equipment needs to be continuously improved. Currently, the commonly used method for removing small fruits in our country is still simple mechanical screening. For example, fruits are screened by a conveyor belt with different hole diameters. This method has low sorting efficiency and inaccurate sorting accuracy.

[0003] Therefore, how to improve the sorting efficiency is an important technical problem that urgently needs to be solved at present. Utility Model Content

Detailed Embodiments

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. It can be understood that the accompanying drawings are only for reference and illustration, and are not used to limit the present application. The connection relationships shown in the drawings are only for clear description and do not limit the connection methods.

[0033] Specifically, as Figures 1-6 shown, in the embodiment of the present application, a front-end feeding device for sorting cashew nuts is provided. This device automatically screens and finely selects cashew nuts, and sorts cashew nuts of corresponding different sizes and qualities. The specific sorting process includes a primary vibrator 200, a multi-roller leakage system 300, a secondary vibrator 400, a tertiary vibrator 500, and a differential mechanism 600, which are arranged in sequence to sort the cashew nuts.

[0034] The specific sorting process is as follows:

[0035] As Figure 2 shown, the sorting process is set on the bracket 100. A feed bin 110 is installed on the bracket 100. An outlet 111 is opened at the bottom of the feed bin 110. Cashew nuts are placed in the feed bin 110 and discharged through the outlet 111 under the action of their own gravity, falling into the primary vibrator 200.

[0036] A V-shaped groove 700 is provided on the primary vibrator 200, and the V-shaped groove 700 is horizontally placed on the bracket 100. A vibration motor 420 is provided at the bottom of the V-shaped groove 700. The vibration motor 420 vibrates the V-shaped groove 700 in the horizontal direction, so that when the cashew nuts fall into the V-shaped groove 700, the cashew nuts are arranged one by one through the horizontal vibration frequency, and at the same time, the cashew nuts are also transported to the multi-roller leakage system 300.

[0037] In the primary vibrator 200, the frequency of the vibration motor 420 is set between 5 - 10 Hz, which can evenly distribute the cashew nuts in the V-shaped groove 700, avoid the accumulation of cashew nuts, and facilitate the screening of cashew nuts.

[0038] The cashew nuts are initially screened in a multi-roller leakage system 300, which mainly consists of multiple groups of two rollers. Specifically, in a group of rollers, a first roller 310 and a second roller 320 are provided, and the first roller 310 and the second roller 320 are arranged side by side. A gap is formed between the first roller 310 and the second roller 320, and this gap is a fixed spacing 340. When the diameter of the cashew nut is greater than the fixed spacing 340, the cashew nut will slide down along the first roller 310 and the second roller 320 and enter the secondary vibrator 400; when the diameter of the cashew nut is less than the fixed spacing 340, the cashew nut will fall in the fixed spacing 340 and thus fall onto the transition plate 350, thereby realizing the sorting of the cashew nuts.

[0039] In the above process, to achieve this process, more specifically, the first roller 310 and the second roller 320 are rotationally driven by a motor 330, and the rotation directions of the first roller 310 and the second roller 320 are opposite and the rotation speeds are the same, so that the cashew nuts can move linearly and stably for sorting movement from the multi-roller leakage system 300.

[0040] Among them, when the cashew nuts fall onto the transition plate 350, the cashew nuts on the transition plate 350 are basically small cashew nuts and defective cashew nuts. Such cashew nuts can be processed by manual screening or machines in the subsequent process, and further sorting can also be realized. This process is not specifically described in this article.

[0041] When the cashew nuts enter the secondary vibrator 400, a V-shaped groove 700 is provided in the secondary vibrator 400. There are multiple V-shaped grooves 700 arranged in the secondary vibrator 400, and the multiple V-shaped grooves 700 are arranged in sequence to avoid chaotic accumulation of the cashew nuts.

[0042] In the embodiment of the present application, the secondary vibrator 400 is horizontally placed on the bracket 100, and a vibration motor 420 and a vibration spring 410 are provided below the V-shaped groove 700 in the secondary vibrator 400. The vibration motor 420 and the vibration spring 410 are both connected to the V-shaped groove 700, and the vibration motor 420 drives the V-shaped groove 700 to vibrate in the horizontal direction, and the vibration frequency is set between 5 - 10 Hz to realize the movement of the cashew nuts from the secondary vibrator 400 to the tertiary vibrator 500.

[0043] The same V-shaped grooves 700 are also provided on the three-stage vibrator 500. The number of the V-shaped grooves 700 is equivalent to that of the V-shaped grooves 700 on the two-stage vibrator 400, so that the cashew nuts always enter the three-stage vibrator 500 from the two-stage vibrator 400 in a linearly arranged manner. And in the three-stage vibrator 500, a vibration motor 420 is also provided at the position below the V-shaped groove 700. The vibration motor 420 vibrates the V-shaped groove 700, and the V-shaped groove 700 is inclined downward at a certain inclination angle of 12°, which is convenient for the movement of the cashew nuts.

[0044] After passing through the three-stage vibrator 500, the cashew nuts enter the differential mechanism 600. The differential mechanism 600 includes two groups of belts 610. The two groups of belts 610 are arranged to form a V-shaped groove 700. After the cashew nuts pass through the three-stage vibrator 500, they enter the V-shaped groove 700 on the differential mechanism 600. The rotation of the belts 610 drives the moving speed of the cashew nuts, which is convenient for the cashew nuts to enter the sorting fruit tray in the sorting system 800 to complete the preliminary sorting process before the fruit tray sorting.

[0045] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
