Description

Technical Field

[0001] This utility model relates to the field of shelling technology, and in particular to a horizontal pistachio shelling machine. Background Technology

[0002] Pistachios are a popular nut, and the shelling process directly affects the kernel integrity and product quality. Traditional manual shelling methods are inefficient, labor-intensive, and prone to damaging the kernels, failing to meet the demands of large-scale production. Therefore, the development of automated shelling equipment has become an important direction for the nut processing industry.

[0003] Currently, although some pistachio shelling equipment has appeared on the market, these traditional devices have obvious defects in structural design and functional implementation, making it difficult to adapt to the actual needs of pistachio processing. Most traditional pistachio shelling equipment uses a fixed-gap shelling structure, which is difficult to flexibly adjust according to the size differences of different batches and sizes of pistachios. When processing larger pistachios, a fixed gap that is too small will result in excessive pressure on the kernel during the shelling process, exacerbating kernel damage; while when processing smaller pistachios, a fixed gap that is too large will not effectively compress the shell, resulting in incomplete shelling. A large number of unshelled pistachios need to be processed again, which not only increases processing steps and costs, but also reduces overall production efficiency. Utility Model Content

[0004] This invention provides a horizontal pistachio shelling machine, which can solve the problem mentioned in the background art that most traditional pistachio shelling equipment adopts a fixed-gap shelling structure, making it difficult to flexibly adjust according to the size differences of different batches and sizes of pistachios.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figure 1-6 As shown, this utility model proposes a horizontal pistachio shelling machine, including: a frame 1, a drive roller 2, a drive roller toothed plate 3, an adjusting toothed plate 4, and an adjusting mechanism 5; the drive roller 2 is mounted on the frame 1 via bearings 6, the drive roller toothed plate 3 is mounted on the outer arc surface of the drive roller 2, and the drive roller 2 is connected to a reduction motor 7; the adjusting mechanism 5 includes an adjusting plate 51 and a driving assembly 52 for moving the adjusting plate 51, the adjusting plate 51 is mounted on the frame 1 via a guide scale plate 53; the adjusting toothed plate 4 is mounted on the inner arc surface of the adjusting plate 51, and together with the drive roller toothed plate 3, forms a shelling area.

[0020] In this embodiment, by controlling the operation of the reduction motor 7, the active roller 2 and the active roller toothed plate 3 can be driven to rotate. The rotating active roller toothed plate 3 can peel the pistachios that enter between the active roller toothed plate 3 and the adjusting toothed plate 4. The adjusting toothed plate 4 is fixed on the inner arc surface of the adjusting plate 51 and remains stationary. When the material enters the peeling area, the active roller toothed plate 3 rotates with the active roller and forms relative motion with the stationary adjusting toothed plate 4. This not only generates a squeezing force on the material, but also creates strong friction through the relative sliding between the toothed plates. Under the dual action, the pistachio shell structure can be quickly destroyed. The adjusting plate 51 is slidably installed on the frame 1 through the guide scale plate 53. The drive component 52 can directly drive the adjusting plate 51 to translate along the guide scale plate 53, thereby driving the adjusting toothed plate 4 to move synchronously, changing the gap between the adjusting toothed plate 4 and the active roller toothed plate 3, which facilitates peeling pistachios of different sizes and enhances the applicability of the device.

[0021] Two drive components 52 and two guide scale plates 53 are provided. A frequency converter 13 is provided on one side of the frame 1. The frequency converter 13 is electrically connected to the geared motor 7. The speed of material entering the peeling area can be controlled by adjusting the motor speed.

[0022] like Figure 1 and Figure 2As shown, a receiving hopper 8 is provided on the frame 1, and a receiving box 9 is provided at the discharge end of the receiving hopper 8. A material handling vibrator 10 is connected to the bottom of the receiving box 9. The material handling vibrator 10 is installed on the frame 1. A feeding hopper 11 is provided at the discharge end of the receiving box 9, and a discharge hopper 17 is provided at the bottom of the drive roller 2. The receiving box 9 and the material handling vibrator 10 form a key connection link for temporary storage and uniform feeding. The material received by the receiving hopper 8 first falls into the receiving box 9 to form a material buffer pool, which prevents the fluctuation of the material quantity in the receiving hopper 8 from being directly transmitted to the feeding link. Subsequently, the material handling vibrator 10 conveys the material in the receiving box to the feeding hopper 11 at a uniform rate through high-frequency low-amplitude vibration, ensuring that the amount of material entering the shelling area every second is stable within the optimal processing range of the equipment.

[0023] There are two receiving hoppers 8 and two material handling vibrators 10, arranged symmetrically on the left and right. The two receiving hoppers 8 and the two material handling vibrators 10 are arranged symmetrically on the left and right to form a parallel dual material conveying channel. The material received by the left receiving hopper 8 is temporarily stored in the left receiving box 9 and then conveyed to the feeding hopper at a uniform speed by the left material handling vibrator 10. The right channel completes the same process simultaneously. After the two materials merge in the feeding hopper, they enter the shelling area evenly.

[0024] Specifically, the discharge end of the feed hopper 11 is equipped with a baffle 12, and the discharge end of the baffle 12 is located in the shelling area; the baffle 12 can accurately guide the material into the space between the active roller tooth plate 3 and the adjusting tooth plate 4.

[0025] like Figure 4 and Figure 5 As shown, the drive assembly 52 includes an adjusting shaft 521 and a limiting plate 522. The adjusting shaft 521 is threadedly connected to the limiting plate 522, which is mounted on the frame 1. An adjusting handwheel 523 is provided at the end of the adjusting shaft 521. The adjusting shaft 521 and the limiting plate 522 are threadedly connected, and the screw drive characteristics of the thread are used to achieve fine adjustment of the gap. When the operator rotates the adjusting handwheel 523, the adjusting shaft 521 can be moved on the limiting plate 522, which in turn drives the adjusting plate 51 and the adjusting toothed plate 4 to move. The gap between the adjusting toothed plate 4 and the drive roller toothed plate 3 can be adjusted to ensure that each batch of material can be shelled at the optimal gap. This avoids incomplete shelling due to excessive gap and damage to the kernels due to insufficient gap, thereby further improving the whole kernel rate and shelling stability.

[0026] The guide scale plate 53 is provided with a scale 531; the scale 531 allows for convenient and precise adjustment of the distance between the active roller tooth plate 3 and the adjusting tooth plate 4.

[0027] like Figure 1 and Figure 6As shown, the active roller 2 is provided with an active roller cover 14, the top of the frame 1 is equipped with a top cover 15, and the frame 1 is surrounded by a surrounding plate 16. The active roller 2 can be protected by the active roller cover 14, and the internal components of the machine can be protected by the top cover 15 and the surrounding plate 16.

[0028] Working principle: By controlling the operation of the geared motor 7, the active roller 2 and the active roller toothed plate 3 can be rotated. The rotating active roller toothed plate 3 can peel the pistachios that enter between the active roller toothed plate 3 and the adjusting toothed plate 4. The adjusting toothed plate 4 is fixed on the inner arc surface of the adjusting plate 51 and remains stationary. When the material enters the peeling area, the active roller toothed plate 3 rotates with the active roller and forms relative motion with the stationary adjusting toothed plate 4. This not only generates a squeezing force on the material, but also creates strong friction through the relative sliding between the toothed plates. Under the dual action, the pistachio shell structure can be quickly destroyed. The adjusting plate 51 is slidably installed on the frame 1 through the guide scale plate 53. The drive component 52 can directly drive the adjusting plate 51 to translate along the guide scale plate 53, thereby driving the adjusting toothed plate 4 to move synchronously, changing the gap between the adjusting toothed plate 4 and the active roller toothed plate 3, which facilitates peeling pistachios of different sizes.

[0029] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
