Abstract
Description
Technical Field
[0001] This utility model relates to a pre-processing device for fruit and vegetable processing, specifically, to a screening and conveying device for fresh black goji berries. Background Technology
[0002] After harvesting, black goji berries typically need to be washed using a bubble machine. This machine churns the berries in a pool of water, washing away surface dirt. However, after washing, the output berries often still contain impurities such as leaves and sand. To meet subsequent processing standards, these impurities need to be sieved out. Currently, a common method is to transport the washed berries via a conveyor belt, during which time the leaves and sand are manually removed. However, this method is labor-intensive and inefficient.
[0003] To address the issue of manual sieving, the applicant designed a black goji berry raw material impurity removal device in patent application number 202420199082.6. This device uses a hot air device installed below a conveyor belt to blow hot air onto the black goji berries on the belt. A vibration drive device drives the upper part of the conveyor belt to vibrate up and down, causing the black goji berries to tumble on the conveyor belt, drying them while simultaneously blowing away leaves and sand. However, in actual use, the applicant found that because the hot air device blows vertically upwards, some leaves and sand, after being blown up, do not detach from the conveyor belt and fall back down. Therefore, a small amount of leaves and sand still remain mixed in with the black goji berries.
[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention
[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a black goji berry fresh fruit screening and conveying device that can more thoroughly screen leaves and sand based on the device invented by the applicant.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a black goji berry fresh fruit screening and conveying device, comprising a frame, a conveyor belt, a hot air device, a vibration drive device, and an inclined guide vane assembly mounted on the frame. The conveyor belt is mounted on the frame, the hot air device is located directly below the conveyor belt and is used to blow hot air upwards, and the vibration drive device drives the upper belt of the conveyor belt to vibrate up and down; the inclined guide vane assembly is located directly above the conveyor belt, and the inclined guide vane assembly is inclined from a low position on one side of the conveyor belt to a high position on the other side of the conveyor belt.
[0007] Beneficial effects: The washed black goji berries are placed on the conveyor belt and conveyed forward. The shaking drive device drives the upper belt of the conveyor belt to shake up and down, causing the black goji berries to tumble. The hot air device blows hot air upwards to dry the passing black goji berries and blow away any leaves and sand mixed in. The inclined guide vane assembly can guide the hot air to turn and carry the leaves and sand aside, preventing them from falling back onto the conveyor belt after being blown vertically up.
[0008] Based on the above, the hot air device includes a plurality of hot air outlets spaced apart and arranged directly below the conveyor belt, and a hot air fan is connected to each of the hot air outlets. The inclined guide vane assembly is composed of a plurality of spaced guide vanes, and the guide vanes are arranged one-to-one above the plurality of hot air outlets.
[0009] Beneficial effects: Dividing the inclined guide vane assembly into several guide vanes can reduce the amount of material used and lower equipment modification costs. On the other hand, hot air at the edges can also escape from the gaps in the middle of the vanes, preventing hot air at the edges from being slowed down by the material and causing leaves and sand to fall back onto the conveyor belt more easily.
[0010] Based on the above, the vibration drive device includes a plurality of eccentric rod mechanisms spaced apart. Each eccentric rod mechanism includes a drive motor, a rotating shaft, and a cam mounted on the rotating shaft. The rotating shaft passes between the upper and lower belt bodies of the conveyor belt and is mounted on the frame at both ends. The drive motor drives the rotating shaft to rotate, and the cam drives the upper belt body of the conveyor belt to vibrate up and down by intermittently contacting it.
[0011] Based on the above, the inclined wind guide plate assembly adopts a flat plate with an inclination angle of 45°-60°.
[0012] Based on the above, the frame includes two side support plates of equal height, the conveyor belt is installed between the two side support plates, the bottom end of the inclined air guide plate assembly is installed at the top of one side support plate, and the cross-section of the inclined air guide plate assembly is an arc shape with the top of the other side support plate as the center and the distance between the two side support plates as the radius.

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments. Example 1
[0018] like Figure 1 and Figure 2 As shown, a black goji berry fresh fruit screening and conveying device includes a frame, a conveyor belt 2, a hot air device, a vibration drive device, and an inclined guide vane assembly installed on the frame. The frame includes two side support plates 1 of equal height, and the conveyor belt 2 is installed between the two side support plates 1.
[0019] The hot air device specifically includes a plurality of hot air outlets 8 spaced apart and arranged directly below the conveyor belt 2. Each hot air outlet 8 is connected to a hot air blower, which supplies hot air to the hot air outlets 8. The hot air outlets 8 are used to blow hot air directly upwards.
[0020] The vibration drive device specifically includes multiple eccentric rod mechanisms spaced apart. Each eccentric rod mechanism includes a drive motor 5, a rotating shaft 6, and a cam 7 mounted on the rotating shaft 6. The rotating shaft 6 passes between the upper and lower belt bodies of the conveyor belt and is mounted on the frame 1 at both ends. The drive motor 5 drives the rotating shaft 6 to rotate, and the cam 7 drives the upper belt body of the conveyor belt to vibrate up and down by intermittently contacting it.
[0021] The inclined wind guide plate assembly is located directly above the conveyor belt 2. The inclined wind guide plate assembly is inclined from a low position on one side of the conveyor belt 2 toward a high position on the other side of the conveyor belt 2. The inclined wind guide plate assembly is a flat plate with an inclination angle of 45°-60°.
[0022] In practical use, the washed black goji berries are placed on the conveyor belt 1 and conveyed forward with the conveyor belt 1. Each drive motor 5 drives the cam 7 to rotate through the rotating shaft 6. The cam 7 causes the upper belt of the conveyor belt 1 to shake up and down, making the black goji berries tumble. Several hot air outlets 8 blow hot air upwards to dry the passing black goji berries and blow away any mixed leaves and sand. The inclined guide vane assembly can guide the hot air to turn and take the leaves and sand aside, so that they are not blown vertically up and fall back onto the conveyor belt.
[0023] Preferably, the inclined guide vane assembly consists of several spaced-apart guide vanes 3, which are arranged one-to-one above the multiple hot air outlets 8, with gaps 4 formed between them. This reduces the amount of material used, lowering equipment modification costs. Furthermore, the hot air from the edges can escape through the gaps 4 in the vanes, carrying leaves and sand to higher ground, preventing the hot air from being slowed down by the vanes and causing leaves and sand to fall back onto the conveyor belt 1 more easily. Example 2
[0024] like Figure 3 As shown, the bottom end of the inclined wind deflector assembly is installed on the top of a side support plate 1. The cross-section of the inclined wind deflector assembly is an arc shape with the top of the other side support plate 1 as the center and the distance between the two side support plates 1 as the radius. Since the hot air blows vertically upward, when the leaves and sand it carries hits the inner wall of the inclined wind deflector assembly, they will bounce off the outer side of the opposite side support plate 1. Compared with the flat plate design in Embodiment 1, this arc design allows for a lower height and a gentler hot air deflection.
[0025] Experiments showed that the applicant's previously designed device (i.e., the patent cited in the background art) had five hot air outlets 8 spaced apart below the conveyor belt 2, and a small amount of leaves and sand were visibly mixed into the product. However, with the device in the two embodiments described above, which has four hot air outlets 8 spaced apart below the conveyor belt 2, the leaves and sand mixed into the product are completely invisible to the naked eye.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
