Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a screening device that facilitates material handling. Background Technology

[0002] In almond processing, the screening process is a crucial step in ensuring product quality. It is necessary to remove impurities, broken pieces, and irregularly shaped particles, and to grade them according to specifications. However, traditional screening equipment has significant limitations. First, almonds, due to their oil content, easily adhere to the screen, resulting in fine particles or debris remaining in the screen holes and dead corners of the equipment. Conventional vibrating screens or cyclone separators are difficult to clean thoroughly, requiring frequent shutdowns for disassembly and cleaning, which reduces production efficiency. Second, traditional equipment is mostly deep-cavity and enclosed, making it difficult for tools to reach the bottom or edges when removing materials. Especially for sticky almond residue, manual scraping is time-consuming, laborious, and easily contaminates the material. Third, almond grading often requires a combination of multiple screens. Existing devices are mostly fixed designs, making the process of adjusting the screen hole size and changing the screen cumbersome and inflexible. Food processing has high hygiene requirements.

[0003] Secondly, in the almond processing field, screening devices are key equipment for achieving efficient sorting. As an agricultural product with high nutritional and medicinal value, almonds need to be screened to remove impurities such as broken shells and sand and graded during processing to ensure the quality of the finished product. Existing screening equipment mostly adopts a fixed screen structure, which requires manual screening of almonds layer by layer. Especially for multi-layer screen grading devices, a lot of time is required, which reduces the screening efficiency of the equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a screening device that facilitates material handling. It aims to improve the problem that existing screening equipment often uses a fixed screen structure, requiring manual screening of almonds layer by layer, which is especially time-consuming for multi-layer screen grading devices.

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.

[0032] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a screening device for easy material handling, comprising a workbench 6, a U-shaped frame 1 fixedly connected to the top rear side of the workbench 6, a large screen plate 3 slidably connected to the top inner side of the U-shaped frame 1, a medium screen plate 8 slidably connected to the middle inner side of the U-shaped frame 1, a small screen plate 7 slidably connected to the bottom inner side of the U-shaped frame 1, and L-shaped plates 9 fixedly connected to the left and right front ends of the U-shaped frame 1. The rear sides of the L-shaped plates 9 are slidably connected to the outer walls of the corresponding large screen plate 3, medium screen plate 8, and small screen plate 7, respectively. A handle 11 is fixedly connected to the front side of each of the large screen plate 3, medium screen plate 8, and small screen plate 7. Hollow columns 4 are fixedly connected to adjacent sides of multiple L-shaped plates 2 9. T-shaped rods 16 are slidably connected to the inner side of hollow columns 1 4. Spring columns 17 are fixedly connected to the other end of T-shaped rods 16. Hollow columns 2 18 are fixedly connected to the other end of spring columns 17. Slide grooves 15 are opened on the rear side of U-shaped frame 1. Material receiving boxes 10 are slidably connected to the inner side of slide grooves 15. Pushing mechanism 2 is set on the top right side of U-shaped frame 1. Pushing mechanism 2 is used to push and reduce manpower. Mounting plates 12 are fixedly connected to the middle of the left and right sides of U-shaped frame 1. Mounting plates 12 are fixedly connected to the opposite sides of the two mounting plates 12.

[0033] Specifically, handles 11 are fixedly connected to the front sides of the large sieve plate 3, the medium sieve plate 8, and the small sieve plate 7. Using handles 11, operators can easily pull the sieve plates out of or into the U-shaped frame 1. Hollow column 4 is a hollow cylindrical structure that provides guidance for sliding. Inside hollow column 4, a T-shaped rod 16 is slidably connected. The main body of the T-shaped rod 16 is a cylindrical rod, which acts as a limit to prevent it from completely sliding out of hollow column 4. The other end of the spring column 17 is fixedly connected to a hollow column 18, also a hollow cylinder, whose inner diameter matches the main body of the T-shaped rod 16, allowing the T-shaped rod 16 to slide freely between hollow column 4 and hollow column 18.

[0034] Please see the appendix Figure 4 - Appendix Figure 6 The pushing mechanism 2 includes an L-shaped plate 201. The left side of the L-shaped plate 201 is fixedly connected to the top right side of the U-shaped frame 1. A telescopic rod 202 is fixedly connected to the front left end of the L-shaped plate 201. A connecting column 203 is fixedly connected to the output end of the telescopic rod 202. A locking hole 204 is provided on the outer wall of the connecting column 203. A T-shaped buckle 208 is engaged with the inner side of the locking hole 204. A locking strip 205 is provided in the middle front side of the large screen plate 3. A circular hole 206 is provided on the top left side of the locking strip 205. The inner side of the circular hole 206 is slidably connected to the outer wall of the connecting column 203. A locking hole 207 is provided on the rear top side of the locking strip 205.

[0035] Specifically, the size and shape of the locking hole 204 on the outer wall of the connecting post 203 are matched with the subsequent T-shaped buckle 208 to achieve a stable locking connection. The T-shaped buckle 208 can be easily inserted into the locking hole 204 to form a strong locking structure. This locking connection method is simple and reliable. The connection or separation operation can be completed simply by inserting or pulling the T-shaped buckle 208 into or out of the locking hole 204. During the connection process, the telescopic rod 202 drives the connecting post 203 to extend forward, so that its outer wall slides against the inner side of the circular hole 206. The sliding connection method not only provides a stable guiding effect for the connecting post 203, but also allows the connecting post 203 to be adjusted in position within a certain range to adapt to different needs.

[0036] Please see the appendix Figure 1 - Appendix Figure 3 The outer wall of the card strip 205 is fitted with a handle 11, and multiple handles 11 are fixedly connected at the same horizontal height. The upper left side of the U-shaped frame 1 is fixedly connected with a controller 14, and multiple controllers 14 are electrically connected to the vibrator 13 and the telescopic rod 202 respectively. The middle rear side of the receiving box 10 is fixedly connected with a handle 29. The bottom left and right sides of the U-shaped frame 1 are fixedly connected with support legs 5. Multiple hollow columns 1 4 and hollow columns 2 18 are symmetrically designed, and the two support legs 5 are fixedly connected at the same horizontal height.

[0037] Specifically, the controller 14 is electrically connected to the vibrator 13 and the telescopic rod 202 of the device, respectively. The electrical connection is achieved through high-precision wires and reliable electrical interfaces. The controller 14 can respond to preset programs and operator instructions. As an important part of the screening device, the receiving box 10 has a handle 2 19 fixedly connected to the middle of the rear side of the receiving box 10 by bolt connection to increase the friction when the operator holds it and prevent the hand from slipping.

[0038] Working principle: When screening almond fragments, the almond fragments are first placed on the large sieve plate 3. Then, the large sieve plate 3, the medium sieve plate 8, and the small sieve plate 7 are pulled by the corresponding handles 11, so that they slide along the inner side of the U-shaped frame 1 and the L-shaped plate 9. This causes the T-shaped rod 16 and the spring column 17 to slide back and forth along the inside of the hollow column 4 and the hollow column 18, respectively, thus providing a good assist effect. Finally, the vibration is started by the mounting plate 12 and the vibrator 13, so that almond fragments of different specifications can be screened out. Therefore, it is convenient for operators to use the screened almond fragments, providing a certain degree of convenience and meeting daily use needs.

[0039] Afterwards, the telescopic rod 202 is fixed in conjunction with the L-shaped plate 201. Then, the locking strip 205 is inserted into the inside of the handle 11. The telescopic rod 202 is activated to push the connecting column 203 into the inside of the circular hole 206. At this time, the T-shaped buckle 208 that engages inside the locking hole 207 is removed. The connecting column 203 has a locking hole 204. The T-shaped buckle 208 is then inserted into the locking hole 204 to complete the process. Finally, the telescopic rod 202 is used to push the large screen plate 3, the medium screen plate 8, and the small screen plate 7 for screening. Therefore, it is possible to effectively switch between automatic and manual screening according to the needs of the operator, thereby improving the versatility of the device and increasing the efficiency of the equipment.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
