Description

Technical Field

[0001] This utility model relates to the technical field of jujube processing equipment, and in particular to a continuous jujube processing and impurity removal device. Background Technology

[0002] As a nutritious agricultural product, jujubes require multiple pre-processing steps before processing, among which impurity removal is a crucial step to ensure the quality and efficiency of subsequent processing. From harvesting and transportation to processing, jujubes are easily contaminated with various impurities such as twigs, leaves, sand, and dust. If these impurities are not removed in time, they will not only affect the smooth progress of subsequent processing steps but may also reduce the quality of the jujube product and even affect the normal operation of subsequent processing equipment.

[0003] Existing jujube impurity removal equipment mostly adopts a screening-type impurity removal structure, such as the foreign matter removal machine for jujube impurity removal disclosed in Chinese invention patent CN112139030A, which mainly separates particulate impurities from jujubes through the rotation of the screen body. However, such equipment has obvious limitations: on the one hand, the screening structure can only separate particulate impurities with a large difference in particle size from jujubes. It is difficult to effectively screen irregularly shaped and easily entangled impurities such as branches and leaves. Impurities are easy to clog the screen holes or be discharged with the jujubes, resulting in incomplete impurity removal. On the other hand, the continuous operation capability of existing equipment is weak. In the process of large-scale jujube processing, problems such as feed accumulation and low impurity removal efficiency are prone to occur, which cannot meet the needs of industrial continuous production.

[0004] Therefore, there is an urgent need for a processing equipment that can efficiently separate leaf and branch impurities from jujubes and achieve continuous impurity removal, in order to solve the technical pain points of existing technologies such as insufficient targeting of impurity removal, low efficiency, and inability to meet the needs of mass production. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a continuous processing and impurity removal device for jujubes, which solves the problem that existing jujube impurity removal devices are unable to effectively separate branch and leaf impurities.

[0006] The technical solution of this utility model is implemented as follows: A continuous processing and impurity removal device for jujubes includes a hoist, a separator, and a conveyor arranged in sequence. The separator includes an inclined bottom conveyor belt that can transport jujubes laterally, and a collection hopper is provided at the end of the bottom conveyor belt to collect impurities transported laterally by the bottom conveyor belt. A separation scraper structure is provided on the bottom conveyor belt to scrape off the jujubes transported along the bottom conveyor belt. A discharge structure is connected to the tail of the separation scraper structure, and the discharge structure cooperates with one end of the conveyor. A cleaning mechanism is provided on the hoist, and a drainage filter assembly is provided below the hoist.

[0007] Preferably, the end of the bottom conveyor belt closest to the elevator is higher than the end furthest from the elevator, and the bottom conveyor belt is mounted on a support. The separating scraper structure includes a crossbeam fixedly mounted on the support, with a pair of scrapers bolted to the crossbeam, and the tail of the scrapers connected to the unloading structure. The crossbeam has elongated holes, and the scrapers are bolted to these holes, with the two scrapers arranged in a V-shape.

[0008] Preferably, the feeding structure includes a flow guide hood, with two scrapers fixedly connected to both sides of the flow guide hood, the bottom of the flow guide hood being flush with the surface of the bottom conveyor belt, and a hopper fixedly installed on the conveyor, the hopper being located below the flow guide hood.

[0009] Preferably, the collection hopper includes a guide hopper fixedly mounted on a support, with an opening at the top that mates with the end of the bottom conveyor belt, and a collection basket at the bottom of the guide hopper. The conveyor is fixedly mounted inside the water collection tank, and the cleaning mechanism includes a support shell fixedly mounted on the water collection tank, with several branch pipes fixedly mounted on the support shell. Each branch pipe is connected to a water supply pipe, and each branch pipe is equipped with a nozzle.

[0010] Preferably, the drainage filtration assembly includes a filter tank located at the lower end of the water collection tank, a filter screen is installed inside the filter tank, and the lower part of the side wall of the filter tank is connected to a drainage pipe. Both the water collection tank and the conveyor are inclined, and a valve is installed on the drainage pipe. The elevator is a bucket elevator or a belt conveyor, and the conveyor is a roller conveyor.

[0011] The beneficial effects of this utility model are: through optimized structural design, it achieves efficient separation of jujubes from branches, leaves, sand, and other impurities, while also possessing continuous operation capabilities, making it suitable for large-scale industrial processing needs. Highly targeted and effective impurity removal: By using an inclined bottom conveyor belt in conjunction with a separating scraper structure, gravity and guidance are used to effectively separate jujubes from leaf and branch impurities. At the same time, a washing mechanism is used to clean the fine impurities on the surface of the jujubes. Compared with traditional screening-type impurity removal equipment, it can remove a variety of types of impurities and remove impurities more thoroughly.

[0012] Achieving continuous, large-scale processing: The equipment, through the sequential coordination of the elevator, separator, and conveyor, forms a continuous impurity removal process, requiring no frequent manual intervention. This meets the needs of large-scale industrial jujube processing and significantly improves impurity removal efficiency. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 , 2 As shown in Embodiment 1, a continuous processing and impurity removal device for jujubes includes a hoist 1, a separator 2, and a conveyor 3 arranged sequentially. The separator 2 includes an inclined bottom conveyor belt 4. Specifically, in this embodiment, the end of the bottom conveyor belt 4 near the hoist 1 is higher than the end away from the hoist 1, and the inclination angle is set to 15°~30°. In this embodiment, an inclination angle of 20° is used, which allows the jujubes to roll naturally to a lower position using gravity. The bottom conveyor belt 4 is mounted on a support 10. The bottom conveyor belt 4 can transport jujubes laterally, and a collection hopper 5 is provided at the end of the bottom conveyor belt 4 to collect impurities transported laterally by the bottom conveyor belt 4. A separation scraper structure 6 is also provided on the bottom conveyor belt 4 to scrape off the jujubes transported along the bottom conveyor belt 4.

[0017] The tail end of the separating scraper structure 6 is connected to the feeding structure 7, which is matched with one end of the conveyor 3. The elevator 1 is equipped with a cleaning mechanism 8, and a drainage filter assembly 9 is provided below the elevator 1.

[0018] As a further specific implementation, the elevator 1 is a bucket elevator or a belt conveyor. In this embodiment, the elevator can vertically lift the jujubes from the ground to the separator 2. The bucket elevator is suitable for conveying large quantities of jujubes under vertical or steep incline conditions, and has high conveying efficiency. The belt conveyor has a simple structure and is easy to maintain, and can be selected according to site requirements. In addition, the conveyor 3 is a roller conveyor. The roller conveyor can reduce the contact area with the jujubes, avoid water accumulation after washing, and facilitate wastewater dripping into the drainage filter assembly 9.

[0019] In this embodiment, since the bottom conveyor belt is inclined and transports laterally, the jujubes lifted to the upper end of the bottom conveyor belt by the elevator roll down to the lower part of the bottom conveyor belt under the action of gravity. Meanwhile, impurities such as branches and leaves mixed in with the jujubes move towards the end of the conveyor belt with the lateral movement of the bottom conveyor belt and finally fall into the collection basket of the impurity collection hopper, completing the initial impurity removal.

[0020] Example 2: A continuous processing and impurity removal device for jujubes. Based on Example 1, the separating scraper structure 6 includes a crossbeam 11 fixedly mounted on a support 10. A pair of scrapers 12 are bolted to the crossbeam 11, and the tail of the scrapers 12 is connected to the feeding structure 7. A gap is left between the scrapers and the bottom conveyor belt, the gap being smaller than the size of the jujubes. The gap allows some rolling impurities to pass through while preventing jujubes from passing through.

[0021] The crossbeam 11 has elongated holes 13, and the scraper 12 is connected to the elongated holes 13 by bolts. In this embodiment, two crossbeams are provided to provide stable support. The elongated holes allow for fine-tuning of the scraper's position, making it easy to adapt to the lifting height and position of the hoist during actual use, so that it corresponds to the falling path of the jujubes. The scraper 12 is made of stainless steel, and the two scrapers 12 are arranged in a V-shape with an included angle of 60°~90°, preferably 75° in this embodiment. The feeding structure 7 includes a guide shroud 14, with the two sides of the guide shroud 14 fixedly connected to the two scrapers 12 respectively. The bottom of the guide shroud 14 is flush with the surface of the bottom conveyor belt 4. A hopper 15 is fixedly installed on the conveyor 3, located below the guide shroud 14, to ensure that the jujubes fall accurately into the hopper 15.

[0022] In addition, the collection hopper 5 includes a guide hopper 16 fixedly mounted on the support 10. The guide hopper 16 is made of stainless steel, and the top opening size is adapted to the end of the bottom conveyor belt 4. A storage basket 17 is provided on the ground at the bottom of the guide hopper 16 to facilitate the collection of impurities such as branches and leaves and to facilitate regular cleaning.

[0023] Example 3: A continuous processing and impurity removal device for jujubes, based on Example 2, such as... Figure 1 , 3As shown in Figure 4, the conveyor 3 is fixedly installed in the water collection tank 18. The cleaning mechanism 8 includes a support shell 19 fixedly installed on the water collection tank 18. Several branch pipes 20 are fixedly installed on the support shell 19. Each branch pipe 20 is connected to a water supply pipe 21. Each branch pipe 20 is equipped with a nozzle 22. In actual use, clean water is sprayed onto the jujubes on the conveyor through the nozzles to clean the dust and fine impurities on the surface of the jujubes and improve the cleanliness of the jujubes. The water collection tank is used to collect cleaning wastewater to prevent sewage from overflowing and polluting the environment.

[0024] The drainage filtration assembly 9 includes a filter tank 23 located at the lower end of the water collection tank 18. A filter screen 24 is installed inside the filter tank 23. The lower part of the side wall of the filter tank 23 is connected to the drainage pipe 25. The pore size of the filter screen 24 is 0.5~1mm, which can filter out small impurities in the wastewater and prevent the drainage pipe from being blocked. The filtered wastewater can be discharged or recycled through the drainage pipe, thus saving water resources.

[0025] The water collection tank 18 and the conveyor 3 are both inclined, which can lift the jujubes to meet the height requirements of the actual subsequent processing steps, and also facilitate the flow of wastewater to the filter tank 23. The drainage pipe 25 is equipped with a valve 26, which can be used to control the start and end of the drainage process.

[0026] The working process of the above embodiments: Feeding and conveying: Pour the dates to be cleaned into the feed inlet of the elevator 1, and the elevator 1 will convey the dates to the bottom conveyor belt 4 of the separator 2.

[0027] Impurity separation: The bottom conveyor belt 4 conveys the jujubes laterally. Under the action of gravity, the jujubes roll down the conveyor belt. Impurities such as branches and leaves move with the conveyor belt to the end and fall into the collection basket 17 of the collection hopper 5. At the same time, the figure-eight scraper 12 scrapes the jujubes off the bottom conveyor belt 4 to prevent them from falling into the collection basket as they roll down. The scraped jujubes are guided by the guide hood 14 to the hopper 15 of the conveyor 3.

[0028] Cleaning and impurity removal: Water supply pipe 21 is connected to an external water source, and clean water is sprayed from nozzle 22 through branch pipe 20 to clean the jujubes on conveyor 3, removing surface dust, fine sand and other impurities; cleaning wastewater falls into water collection tank 18, flows along the inclined water collection tank 18 to filter tank 23, is filtered by filter screen 24, and is discharged or recycled through drainage pipe 25.

[0029] Subsequent conveying: The cleaned and impurity-removed jujubes are conveyed to the next processing step via conveyor 3, realizing continuous impurity removal operation.

[0030] This utility model, through its reasonable structural design, achieves efficient separation of jujubes from impurities such as branches, leaves, and sand, thoroughly removing impurities and meeting the needs of continuous, large-scale processing. It also has the advantages of flexible structure, convenient maintenance, and protection of jujube quality, making it suitable for the pre-processing steps of various jujube processing enterprises.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
