Description

Technical Field

[0001] This utility model belongs to the field of wolfberry screening technology, specifically, it relates to a gradient-type wolfberry size vibration screening device. Background Technology

[0002] Currently, wolfberry is the mature fruit of Lycium barbarum, a member of the Solanaceae family. It is a natural health product that is both food and medicine, with rich nutritional value and health benefits. It is currently popular among consumers, and the demand for wolfberry in domestic and international markets is showing an increasing trend year by year. As a major wolfberry producer, my country is also seeing an increasing number of wolfberry plants, processors, and traders. Under such circumstances, the problem of wasting dried wolfberry resources in the process of industrial development is becoming more and more serious.

[0003] The traditional method for processing fresh goji berries is to dry them all regardless of size, and then sort them manually or mechanically. The process is: picking → drying → removing impurities → grading → disinfection. The drawback of this method is that smaller fresh goji berries are too small to be sold in the market after drying. It is a pity to discard them, but they are worthless to keep. This undoubtedly leads to a waste of resources.

[0004] According to existing known technologies, multi-layer sieves are used to screen goji berries, forming a multi-gradient screening method. However, multi-layer sieves result in material waste and require a large amount of space, making it impossible to achieve the screening effect with just one set of sieves.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0009] In a preferred embodiment of this utility model, limit frames are symmetrically arranged on the guide plate, the guide plate is slidably connected to each limit frame, each limit frame is fixedly connected to the box body, and each guide plate is provided with a guide groove.

[0010] In a preferred embodiment of this utility model, each guide plate has a guide groove slidably connected to a transmission rod, the guide grooves on the guide plate are inclined to both sides, and each guide plate is fixedly connected to a corresponding movable block.

[0011] In a preferred embodiment of this utility model, the box body is provided with symmetrical sliding grooves, and the end of each movable block is connected to the corresponding sliding groove. The sliding groove at one end of the guide plate of the box body is hollowed out.

[0012] In a preferred embodiment of this utility model, the limiting frames are fixedly connected to each other, and the limiting blocks are arranged in an array within the mounting frame. Each limiting block is slidably connected to the mounting frame and abuts against the transmission rod.

[0013] In a preferred embodiment of the present invention, a discharge surface is fixedly connected to the bottom of the box body. The discharge surface is inclined and the inclination direction of the discharge surface is towards the discharge port. Fixed blocks are symmetrically arranged inside the box body, and each fixed block is fixedly connected to the box body. Movable blocks are arranged between the fixed blocks.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] Please see Figure 1-5 A gradient-type vibrating screening device for goji berries includes a screening component for screening goji berries. The screening component includes a housing 1, a vibrating device 11, a discharge port 12, movable blocks 4, and a reciprocating motor 51. The vibrating device 11 is fixedly connected to the bottom of the housing 1, the discharge port 12 is fixedly installed on one side of the housing 1, and the reciprocating motor 51 is fixedly connected to the housing 1. The movable blocks 4 are arranged in an array inside the housing 1, and each movable block 4 is drivenly connected to the reciprocating motor 51. Goji berries are fed into the housing 1 by manual labor or auxiliary devices. Through the cooperation between the internal components of the screening component, the reciprocating motor 51 changes the spacing between the movable blocks 4 by transmission. By changing the spacing between the movable blocks 4, goji berries of different sizes are screened continuously without the need for multiple screening plates, thus reducing the use of materials and space occupation.

[0028] The box 1 uses vibration device 11 to screen goji berries, and discharge port 12 discharges qualified goji berries. Since vibration device 11 is a well-known technology in the field, it will not be described in detail.

[0029] The housing 1 is fixedly connected to a mounting block 5. A reciprocating motor 51 is fixedly connected to the mounting block 5. A lead screw 53 is fixedly connected to the output end of the reciprocating motor 51. A lifting block 52 is threaded onto the lead screw 53. A guide plate 43 is fixedly connected to the lifting block 52. Limiting frames 2 are symmetrically arranged on the guide plate 43. The guide plate 43 is slidably connected to each limiting frame 2. Each limiting frame 2 is fixedly connected to the housing 1. Each guide plate 43 has a guide groove 44. A transmission rod 42 is slidably connected to each guide groove 44 in the guide plate 43. The guide groove 44 on the guide plate 43 is inclined to both sides. Each guide plate 43 is fixedly connected to a corresponding movable block 4. A sliding groove is symmetrically opened inside the housing 1. The end of each movable block 4 is connected to the corresponding sliding groove. The sliding groove at one end of the guide plate 43 in the housing 1 is hollowed out. The reciprocating motor 51 drives the lead screw 53 to rotate through its output end. The lead screw 53 drives the lifting block 52 through the thread during rotation. The lifting block 52 drives the guide plate 43. The guide plate 43 is limited by the two side limit frames 2 and is driven to rise and fall by the reciprocating motor 51, the lifting block 52 and the lead screw 53. During the rise and fall of the guide plate 43, the position of the guide groove 44 changes. Because the guide groove 44 is set at an angle, the transmission rod 42 sliding in the guide groove 44 is affected by the change in the position of the guide groove 44. Because the movable block 4 slides in the groove in the box 1, the transmission rod 42 is driven to move laterally by the guide groove 44. By changing the distance between the movable blocks 4 through the lateral movement, goji berries of different sizes are screened. First, the distance between the movable blocks 4 is adjusted to the size of small goji berries. After the small goji berries are screened out, the distance between the movable blocks 4 is adjusted to the size of large goji berries. The large goji berries are screened out. Thus, by setting up a single layer of screening, the effect of screening goji berries of different sizes can be achieved, reducing the material waste and space occupation caused by multi-layer screening. Moreover, the aperture of the screening is finely adjusted due to the thread setting of the lead screw 53, making the screening of this device more precise.

[0030] The number of times the spacing between the active blocks 4 can be adjusted is not fixed. Multiple spacing adjustments can be made according to actual usage requirements to screen the goji berries multiple times for fine screening. For ease of understanding, only the two screening results are disclosed in detail in this article. Since the actual usage process is the same, it will not be repeated here.

[0031] The limiting frame 2 is fixedly connected to the mounting frame 3. The mounting frame 3 is arranged in an array of limiting blocks 31. Each limiting block 31 is slidably connected to the mounting frame 3 and abuts against the transmission rod 42. When the position of the transmission rod 42 changes, the transmission rod 42 moves and drives the limiting block 31 to slide within the mounting frame 3. When the vibration screening is performed, the limiting block 31 cooperates with the guide groove 44 to restrict the position of the transmission rod 42, so as to avoid the transmission rod 42 from moving arbitrarily during operation due to the lack of restriction after the position is adjusted, which would affect the screening accuracy.

[0032] The bottom of the box 1 is fixedly connected to a discharge surface 13, which is inclined and faces the discharge port 12. Fixed blocks 41 are symmetrically arranged inside the box 1, and each fixed block 41 is fixedly connected to the box 1. Movable blocks 4 are arranged between the fixed blocks 41. The screened goji berries fall onto the discharge surface 13 and are discharged through the inclined surface. The arrangement of the movable blocks 4 blocks the gap between the movable blocks 4 and the wall of the box 1, so as to avoid the space on both sides being too large and affecting the screening accuracy of the goji berries.

[0033] Working principle: Goji berries are fed into the chamber 1 manually or with auxiliary devices. Through the cooperation of the internal components of the screening assembly, the reciprocating motor 51 changes the spacing between the movable blocks 4 via transmission. By changing the spacing between the movable blocks 4, goji berries of different sizes are screened continuously, eliminating the need for multiple screening plates and reducing material usage and space occupation. The reciprocating motor 51 drives the lead screw 53 to rotate via its output end. During rotation, the lead screw 53 drives the lifting block 52 via its thread. The lifting block 52 drives the guide plate 43, which is restrained by the limit frames 2 on both sides. Driven by the reciprocating motor 51, lifting block 52, and lead screw 53, the guide plate 43 is raised and lowered. During the raising and lowering of the guide plate 43, the position of the guide groove 44 changes. Because the guide groove 44 is tilted, the transmission rod 42 sliding inside the guide groove 44 is affected by the change in the position of the guide groove 44. Because the movable block 4 slides in the groove inside the housing 1, the transmission rod 42 is driven to move laterally by the guide groove 44. By changing the distance between the movable blocks 4 through the lateral movement, goji berries of different sizes are screened. First, the distance between the movable blocks 4 is adjusted to the size of the small goji berries. After the small goji berries are screened out, the distance between the movable blocks 4 is adjusted to the size of the large goji berries. The size of the goji berries is determined by the sieve size, allowing larger berries to be filtered out. This single-layer sieve setup achieves the desired sieve size for different goji berries, reducing material waste and space occupation associated with multi-layer sieve setups. Furthermore, the sieve aperture is finely adjustable due to the threaded design of the lead screw 53, resulting in more precise sieve selection. The spacing between the movable blocks 4 is not fixed and can be adjusted multiple times according to actual usage requirements, allowing for multiple sieve selections and achieving finer sieve selection. For ease of understanding, only two sieve selection scenarios are detailed in this text; the actual usage process is different. Similarly, without further details, during the change of position of transmission rod 42, the movement of transmission rod 42 causes the limiting block 31 to slide within the mounting frame 3. When the vibration screening is performed, the limiting block 31 and the guide groove 44 cooperate to restrict the position of transmission rod 42, preventing the position of transmission rod 42 from moving arbitrarily during operation due to lack of restriction after adjustment, which would affect the screening accuracy. The screened goji berries fall onto the discharge surface 13 and are discharged through the inclined surface. The setting of movable block 4 blocks the gap between movable block 4 and the wall of box 1, preventing the space on both sides from being too large, which would affect the screening accuracy of goji berries.
