Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a raisin sizing machine. Background Technology

[0002] Raisins, as an ancient and classic dried fruit, not only carry rich historical and cultural significance but are also an important part of modern healthy eating. However, from harvesting to finished product, each crystal-clear raisin must undergo a strict selection and processing process to ensure its quality and hygiene standards. In the raisin processing, raisin separation is a key step that directly affects the quality of the raisins and the efficiency of subsequent processing.

[0003] Traditional raisin sizing machines often have complex disassembly methods for their sieve plates. Over long-term use, the surface of the sieve plates is prone to clogging, which not only reduces sizing efficiency but also shortens their service life. In addition, it makes sieve plate maintenance and cleaning more difficult, increasing labor intensity and time costs, thereby leading to reduced production efficiency and increased maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology of raisin granulator has the disadvantage that the screen plates of most raisin granulators are complicated to disassemble, which makes the surface easy to clog, reduces sieving efficiency, shortens life, increases maintenance and cleaning difficulty, and increases labor intensity and time cost, thereby reducing production efficiency and increasing maintenance costs. To this end, we propose a raisin granulator.

[0005] To achieve the above objectives, this application adopts the following technical solution: a raisin sizing machine, comprising a base, a housing fixed to the top of the base, a fixed frame fixed inside the housing, a vibrating motor installed at the bottom of the fixed frame, a sieve plate slidably connected inside the fixed frame, a connecting block fixed to one side of the sieve plate, a fixed shell fixed to one side of the housing, a lower protrusion provided inside the fixed shell, a pull rod fixed to one side of the lower protrusion, the surface of the pull rod slidably connected to the inside of the fixed shell, an upper protrusion slidably connected to the top of the lower protrusion, and an elastic clip fixed to the top of the upper protrusion.

[0006] The connecting block has a T-shaped groove inside that works with the elastic locking block. A spring is fixed to one side of the lower protrusion, and the other end of the spring is fixed to the inside of the fixed shell. Push rods are slidably connected to both sides inside the connecting block, and a push plate is fixed to one end of each push rod.

[0007] Preferably, a first slider is fixed to the bottom of the lower protrusion, and a first groove is provided inside the fixing shell to cooperate with the first slider.

[0008] Preferably, a second slider is fixed on both sides of the upper protrusion, and a second groove is provided inside the fixing shell to cooperate with the second slider.

[0009] Preferably, the base has an inclined groove inside, a collection box is provided at one end of the bottom of the base, a connecting seat is fixed on both sides of the collection box, a fixing seat is fixed on both sides of the base, a threaded rod is rotatably connected inside the fixing seat, and one end of the threaded rod is threadedly connected to the inside of the connecting seat.

[0010] Preferably, a groove is provided on one side of the base, and a lever is slidably connected inside the groove. The bottom of the lever contacts the top of the sieve plate, and a handle is fixed to one end of the lever.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, by pushing the pull rod to move the lower protrusion, the lower protrusion will generate a thrust on the upper protrusion, pushing the upper protrusion to move the elastic locking block towards the top of the connecting block. During the movement, the two ends of the top of the elastic locking block will first contact the inclined surface of the T-slot, and smoothly insert into the interior of the T-slot through compression, thereby fixing the screen plate. At the same time, the above process not only simplifies the installation steps of the screen plate, but also facilitates the subsequent replacement, maintenance and cleaning of the screen plate, effectively reducing screen hole clogging, improving screening efficiency, avoiding device downtime or damage due to screen plate failure, and reducing the cost of replacing the screen plate.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a raisin splitting machine.

[0022] The system includes a base 1, a housing 2 fixed to the top of the base 1, a fixed frame 3 fixed inside the housing 2, a vibration motor 4 installed at the bottom of the fixed frame 3, a sieve plate 5 slidably connected inside the fixed frame 3, a connecting block 6 fixed to one side of the sieve plate 5, a fixed shell 7 fixed to one side of the housing 2, a lower protrusion 8 inside the fixed shell 7, a pull rod 9 fixed to one side of the lower protrusion 8, the surface of the pull rod 9 slidably connected to the inside of the fixed shell 7, an upper protrusion 10 slidably connected to the top of the lower protrusion 8, an elastic locking block 11 fixed to the top of the upper protrusion 10, and a T-slot 12 inside the connecting block 6 that mates with the elastic locking block 11. A spring 15 is fixed to one side of the lower protrusion 8, and the other end of the spring 15 is fixed to the inside of the fixed shell 7. Push rods 19 are slidably connected to both sides inside the connecting block 6. A push plate 20 is fixed to one end of the push rod 19. By pushing the pull rod 9, the lower protrusion 8 is moved, and the lower protrusion 8 will generate a pushing force on the upper protrusion 10, which will push the upper protrusion 10 to move the elastic locking block 11 to the top of the connecting block 6. During the movement, the two ends of the top of the elastic locking block 11 will first contact the inclined surface of the T-slot 12, and smoothly insert into the interior of the T-slot 12 through compression, thereby fixing the screen plate 5. At the same time, the above process not only

[0023] The installation steps of the screen plate 5 are simplified, and the subsequent replacement, maintenance and cleaning of the screen plate 5 are also convenient. This effectively reduces screen hole blockage, improves screening efficiency, avoids equipment downtime or damage due to screen plate 5 failure, and reduces the cost of replacing the screen plate 5.

[0024] Reference Figure 3 As shown in this embodiment: a first slider 13 is fixed to the bottom of the lower protrusion 8, and a first groove 14 that cooperates with the first slider 13 is provided inside the fixing shell 7. By setting the structure of the first slider 13 and the first groove 14, the movement trajectory of the lower protrusion 8 can be restricted to prevent deviation.

[0025] Reference Figure 3As shown in this embodiment: a second slider 17 is fixed on both sides of the upper protrusion 10, and a second groove 18 is provided inside the fixing shell 7 to cooperate with the second slider 17. By setting the structure of the second slider 17 and the second groove 18, the movement path of the upper protrusion 10 is effectively constrained, and the stability of the movement is ensured.

[0026] Reference Figure 4 As shown in this embodiment: the base 1 has an inclined groove 21 inside, and a collection box 22 is provided at one end of the bottom of the base 1. Connecting seats 23 are fixed on both sides of the collection box 22, and fixing seats 24 are fixed on both sides of the base 1. A threaded rod 25 is rotatably connected inside the fixing seat 24. One end of the threaded rod 25 is threadedly connected to the inside of the connecting seat 23. By setting the structure of the collection box 22, the sieving and collection process of raisins is made smoother and more efficient, thereby improving the overall production efficiency.

[0027] Reference Figure 1 and Figure 5 As shown in this embodiment: a groove 26 is provided on one side of the base 1, and a toggle rod 27 is slidably connected inside the groove 26. The bottom of the toggle rod 27 contacts the top of the sieve plate 5, and a handle 28 is fixed to one end of the toggle rod 27. By setting the structure of the toggle rod 27, the raisins on the sieve plate 5 can be continuously pushed and dispersed to prevent them from piling up in one place, thereby ensuring that the raisins can be more evenly distributed on the sieve plate 5.

[0028] Working principle: The user pushes the lever 9 to move the lower protrusion 8, which in turn pushes the upper protrusion 10, causing the elastic locking block 11 to move towards the top of the connecting block 6. During this movement, the two ends of the elastic locking block 11 first contact the inclined surface of the T-slot 12, and then smoothly insert into the interior of the T-slot 12 through compression, thus fixing the screen plate 5. This process not only simplifies the installation steps of the screen plate 5 but also facilitates subsequent replacement, maintenance, and cleaning, effectively reducing...

[0029] To address screen hole blockage, improve screening efficiency, and prevent device downtime or damage due to screen plate 5 malfunction, thus reducing the cost of replacing screen plate 5, the structure of the first slider 13 and the first groove 14 restricts the movement trajectory of the lower protrusion 8 to prevent deviation. The spring 15, when fixing the screen plate 5, is in a compressed state; when releasing the fixation, the push plate 20 drives the push rod 19 to press the two ends of the elastic block 11, causing it to disengage from the T-groove 12. This, in turn, causes the upper protrusion 10 to push against the lower protrusion 8, and works in conjunction with the spring 15. The rebound force pushes the lower protrusion 8 towards the pull rod 9, thereby releasing the fixation of the sieve plate 5, making it easier for operators to replace and maintain it. The structure of the second slider 17 and the second slide groove 18 effectively constrains the movement path of the upper protrusion 10, ensuring the stability of the movement. The structure of the collection box 22 makes the sieving and collection process of raisins smoother and more efficient, improving the overall production efficiency. The structure of the toggle rod 27 can continuously push and disperse the raisins on the sieve plate 5, preventing them from piling up in one place, thereby ensuring that the raisins can be more evenly distributed on the sieve plate 5.

[0030] 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.
