Description

Technical Field

[0001] This utility model belongs to the technical field of wolfberry screening equipment, and more specifically, it relates to a composite screening structure for a wolfberry impurity separation device. Background Technology

[0002] Goji berries are widely used in food, medicine, and other fields, and their quality directly affects product quality and market competitiveness. After harvesting, goji berries often contain impurities such as branches, leaves, stems, and sand. Traditional manual sorting is inefficient and cannot meet the needs of large-scale production. With the development of the industry, the demand for goji berry impurity separation equipment is becoming increasingly urgent.

[0003] Against this backdrop, goji berry impurity separation equipment has emerged, providing a solution to improve goji berry sorting efficiency. However, existing separation equipment has certain limitations in its screening structure design, making it difficult to accurately and efficiently separate impurities of different properties and sizes from goji berries. This not only affects the purity of goji berries but may also damage some high-quality goji berries during the separation process, resulting in resource waste and economic losses. Therefore, developing a more advanced and efficient composite screening structure is key to improving the performance of goji berry impurity separation equipment and promoting the high-quality development of the goji berry industry.

[0004] Based on the above, impurity separation is a crucial step in the processing of goji berries. Existing goji berry impurity separation equipment has unsatisfactory screening effects and struggles to completely remove various impurities from goji berries, such as leaves, stems, and sand. Moreover, traditional equipment is inefficient and energy-intensive, failing to meet the demands of large-scale production. Utility Model Content

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a composite screening structure for a wolfberry impurity separation device, including a side plate 2, a front plate 3, a vibrating motor 4, a fan housing 5, a sieve plate B8, a rear plate 301, and a sieve plate C801; each side of the side plate 2 is provided with two sets of square clamping slots; each side of the front plate 3 and the rear plate 301 is provided with two sets of square clamping blocks, and the square clamping blocks on both sides of the front plate 3 and the rear plate 301 are clamped and connected to the square clamping slots on both sides of the side plate 2; each side of the bottom connecting plate of the vibrating motor 4 is provided with a set of circular connecting holes. Two sets of circular connecting holes on the lower side of the front plate 3 are fastened to the circular connecting holes on both sides of the bottom connecting plate of the vibration motor 4; the bottom of the front plate 3 and the rear plate 301 are welded together by square plates; the bottom square plates of the front plate 3 and the rear plate 301 are movably connected to the circular connecting shafts on the front and rear sides of the screen plate B8 by two sets of circular connecting pipes at the front; each side of the front plate 3 and the rear plate 301 is provided with a set of circular connecting holes, and the rear side of the fan housing 5 is fastened to the circular connecting holes on both sides of the front plate 3 and the rear plate 301.

[0027] The side plate 2 has two sets of square mounting slots on each side, and the feed trough 1 is mounted in the square mounting slots on both sides of the side plate 2. The side plate 2 and the feed trough 1 fit tightly through the square mounting slots, which can make the feed trough 1 firmly fixed on both sides of the side plate. The equipment will not shake or shift during operation, ensuring the smooth and continuous conveying of materials.

[0028] The screen plate B8 has two sets of circular connecting holes on each side of its upper part. A limit spring 802 is movably connected in the two sets of circular connecting holes on one side of the screen plate B8, and a connecting support plate 7 is fastened in the two sets of circular connecting holes on the other side of the screen plate B8. The limit spring 802 is movably connected to the screen plate B8, giving the screen plate a certain elastic buffer space. When the material impacts the screen plate, the spring can effectively reduce shock and prevent the screen plate from being damaged by frequent impacts, thus extending the service life of the screen plate.

[0029] A set of centrifugal blocks 401 are rotatably connected to the rotating shaft on one side of the vibration motor 4. The rotating shaft on one side of the vibration motor 4 is rotatably connected to the circular connecting hole in the middle of the connecting support plate 7. After the vibration motor 4 is started, the rotating shaft drives the centrifugal blocks 401 to rotate at high speed, generating strong vibrations using centrifugal force, and accurately transmitting these vibrations to the connecting support plate 7. The connecting support plate 7 then transmits the vibrations to the screen plate B8, causing the screen plate to vibrate at high frequency.

[0030] Among them, screen plate B8 and screen plate C801 are movably connected by connecting support plate 7 and limiting spring 802, and screen plate C801 is movably connected to screen plate A6 by connecting support plate 7 and limiting spring 802. Screen plate B8, screen plate C801 and screen plate A6 are movably connected by connecting support plate 7 and limiting spring 802. This design allows each layer of screen plates to vibrate in tandem under the action of the vibration motor. Screen plates with different apertures screen the material layer by layer, which greatly improves the fineness and efficiency of screening.

[0031] The blower housing 5 has a set of circular connecting holes on one side, and a small motor 501 is securely connected to the circular connecting holes on one side of the blower housing 5. A fan blade 502 is fitted into the square groove on the front connecting shaft on one side of the small motor 501. The small motor 501 is firmly connected to the blower housing 5, providing a stable power source for the fan blade 502. After starting, it drives the fan blade 502 to rotate at high speed, quickly drawing air into the blower housing 5. The powerful airflow generated by the rotation of the fan blade 502 can efficiently disperse light impurities in the material.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In this invention, goji berries are first poured into the device from the feed trough 1, then fall onto the sieve plate A6. The vibration motor 4 is then started, and the rotation of the vibration motor 4 drives the centrifugal block 401 to rotate, generating vibration that causes the sieve plate A6 to vibrate, thus screening. Because one side of the sieve plate A6 is connected by a limiting spring 802, it can move, and the vibration through the fine holes on the upper part reaches the lower sieve plate B8 and sieve plate C801 for further screening. Then, the small motor 501 is started, driving the fan blade 502 to rotate, generating wind to blow impurities from the goji berries out of the sieve plate, and then they fall to the bottom of the front plate 3 and the rear plate 301. They can be cleaned periodically, and the screening is collected through the square openings on both sides of the front plate 3 and the rear plate 301.

[0034] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
