Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, specifically to a destoning machine for flour processing. Background Technology

[0002] Flour is a powdery substance made from wheat. During the growth, harvesting, transportation, and storage of wheat, various stones and impurities inevitably get mixed in. If these impurities are not effectively removed before flour processing, they will cause serious wear and tear on processing equipment during subsequent grinding and other processing stages, shorten the service life of the equipment, increase equipment maintenance costs, and, more importantly, greatly affect the quality of flour, reduce its purity and taste, and may even pose a potential threat to consumers' health. Wheat as a raw material must first pass through a destoner to remove the sand and stones.

[0003] In the actual operation of traditional destoners, workers generally pour wheat directly onto the filter screen, causing a large amount of wheat to accumulate on the screen. This excessive accumulation of wheat severely hinders the full contact between the wheat and the filter screen, greatly reducing the screening effect. Moreover, the filter screen is subjected to excessive pressure for a long time, which significantly slows down the screening speed, making it impossible to perform continuous screening effectively. This seriously affects the processing progress and increases production costs. Furthermore, cleaning the stones and impurities on the filter screen is quite tedious. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a destoning machine for flour processing, which solves the problem of low screening efficiency in traditional flour processing destoning machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a destoning machine for flour processing, comprising a processing box, a feeding hopper fixedly connected to the top of the processing box through an opening, a discharge port provided at the bottom of the feeding hopper, a drive motor fixedly connected to one side of the top of the processing box through a connector, a rotating rod fixedly connected to the output end of the drive motor through a coupling, one end of the rotating rod penetrating the processing box and extending into the inner cavity of the processing box, an eccentric wheel fixedly connected to the end of the rotating rod extending into the inner cavity of the processing box, U-shaped positioning frames fixedly connected to both sides of the inner cavity of the processing box, a filter frame provided between the two U-shaped positioning frames, and the bottom of the filter frame having an opening... The opening is equipped with a filter screen. Positioning plates that cooperate with a U-shaped positioning frame are fixedly connected to both sides of the filter frame. One side of the positioning plate extends into the interior of the U-shaped positioning frame. A sliding rod is fixedly connected to one side of the inner cavity of the processing box. A sliding cylinder is fitted around and slidably connected to the outer periphery of the sliding rod. A transmission rod is rotatably connected to the bottom of the eccentric wheel via a rotating component. The end of the transmission rod is rotatably connected to the top of the right-side sliding cylinder via a rotating component. A telescopic cylinder is fixedly connected to the bottom of the sliding cylinder. A telescopic plate is slidably connected inside the telescopic cylinder. The top and bottom of the U-shaped positioning frame are provided with through slots that cooperate with the telescopic plate. The top of the positioning plate is provided with a positioning groove that cooperates with the telescopic plate.

[0006] Preferably, a feeding disc is fixedly connected to the top of the inner cavity of the processing box via a rotating component. A half gear is fixedly sleeved on the outer periphery of the rotating rod and located in the inner cavity of the processing box. Several teeth that cooperate with the half gear are fixedly connected to the outer periphery of the feeding disc. Feeding through holes that cooperate with the discharge port are opened on both sides of the top of the feeding disc.

[0007] Preferably, a spring is fixedly connected between the top of the inner cavity of the telescopic cylinder and the top of the telescopic plate, and handles are fixedly connected to both sides of the telescopic plate inside the telescopic cylinder.

[0008] Preferably, the front side of the processing box is hinged with a door through an opening.

[0009] This utility model provides a destoner for flour processing. It has the following beneficial effects:

[0010] (1) This utility model uses a drive motor, a rotating rod, a half gear, a feeding disc and teeth to work together. The half gear drives the feeding disc to rotate, so that the feeding hole and the discharge port are intermittently connected, which avoids a large amount of wheat accumulating on the filter screen at the same time, and ensures that the wheat can be quantitatively distributed on the filter screen, thus improving the screening effect and efficiency. Through the cooperation between the drive motor, eccentric wheel, sliding rod, sliding cylinder, transmission rod, telescopic cylinder, telescopic plate and positioning groove, the filter frame makes reciprocating linear motion, allowing the wheat to tumble and screen fully in the filter frame, which improves the screening efficiency to a certain extent and can quickly separate wheat from impurities such as stones.

[0011] (2) This utility model facilitates the installation and disassembly of the filter frame by means of the cooperation between the telescopic cylinder, telescopic plate, positioning plate, positioning groove, spring and handle. When it is necessary to clean the stones accumulated in the filter frame, or to clean or replace the filter screen, the telescopic plate can be retracted into the telescopic cylinder by squeezing the spring with the handle, and the filter frame can be taken out. The staff can easily complete the operation, saving time and labor costs. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-4This utility model provides a technical solution: a destoning machine for flour processing, including a processing box 1. A door 23 is hinged to the front of the processing box 1 through an opening. A feed hopper 2 is fixedly connected to the top of the processing box 1 through an opening. A discharge port 3 is provided at the bottom of the feed hopper 2. A drive motor 4 is fixedly connected to one side of the top of the processing box 1 via a connector. The drive motor 4 is powered by an external power source. A rotating rod 5 is fixedly connected to the output end of the drive motor 4 via a coupling. One end of the rotating rod 5 passes through the processing box 1 and extends into the inner cavity of the processing box 1. An eccentric wheel 6 is fixedly connected to the end of the rotating rod 5 extending into the inner cavity of the processing box 1. U-shaped positioning frames 7 are fixedly connected to both sides of the inner cavity of the processing box 1. A filter frame 8 is provided between the two U-shaped positioning frames 7. A filter screen 9 is provided at the bottom through an opening. Positioning plates 10 that cooperate with the U-shaped positioning frame 7 are fixedly connected to both sides of the filter frame 8. One side of the positioning plate 10 extends into the interior of the U-shaped positioning frame 7. A slide rod 11 is fixedly connected to one side of the inner cavity of the processing box 1. A slide cylinder 12 is sleeved and slidably connected to the outer periphery of the slide rod 11. A transmission rod 13 is rotatably connected to the bottom of the eccentric wheel 6 through a rotating component. The end of the transmission rod 13 is rotatably connected to the top of the right slide cylinder 12 through a rotating component. A telescopic cylinder 14 is fixedly connected to the bottom of the slide cylinder 12. A telescopic plate 15 is slidably connected inside the telescopic cylinder 14. The top and bottom of the U-shaped positioning frame 7 are provided with through slots that cooperate with the telescopic plate 15. The top of the positioning plate 10 is provided with a positioning groove 16 that cooperates with the telescopic plate 15.

[0019] To avoid excessive material feeding at once affecting the screening of wheat by the filter screen 9, a feeding disc 17 is fixedly connected to the top of the inner cavity of the processing box 1 via a rotating component. A half gear 18 is fixedly sleeved on the outer periphery of the rotating rod 5 within the inner cavity of the processing box 1. Several teeth 19 that cooperate with the half gear 18 are fixedly connected to the outer periphery of the feeding disc 17. Feeding through holes 20 that cooperate with the discharge port 3 are opened on both sides of the top of the feeding disc 17. The half gear 18 cooperates with the feeding disc 17. When the half gear 18 engages with the teeth 19 on the outer periphery of the feeding disc 17... When the 9 phases mesh, they will drive the feeding disc 17 to rotate. During the rotation of the feeding disc 17, when the feeding through hole 20 rotates to align with the discharge port 3, the wheat in the feed hopper 2 will fall into the filter frame 8 below through the discharge port 3 and the feeding through hole 20. As the half gear 18 continues to rotate, when the toothless part of the half gear 18 rotates to be opposite to the tooth 19 of the feeding disc 17, the half gear 18 can no longer drive the feeding disc 17 to rotate, and the feeding disc 17 stops rotating. At this time, the feeding through hole 20 is misaligned with the discharge port 3, and the wheat stops falling.

[0020] Furthermore, in order to facilitate the cleaning of the screened stones and impurities, a spring 21 is fixedly connected between the top of the inner cavity of the telescopic cylinder 14 and the top of the telescopic plate 15. Handles 22 are fixedly connected to both sides of the telescopic plate 15 and inside the telescopic cylinder 14. Vertical grooves that cooperate with the handles 22 are opened on both sides of the telescopic cylinder 14.

[0021] During operation, wheat is placed into the feed hopper 2, which has a discharge port 3 at the bottom. The drive motor 4 is started, and the drive motor 4 drives the half gear 18 to rotate via the rotating rod 5. Since the outer circumference of the feeding disc 17 has teeth 19 that mesh with the half gear 18, the half gear 18 will drive the feeding disc 17 to rotate. When the feeding through hole 20 at the top of the feeding disc 17 is aligned with the discharge port 3, the wheat will fall into the filter frame 8 through the feeding through hole 20. When the feeding through hole 20 is misaligned with the discharge port 3, feeding stops, preventing a large amount of wheat from accumulating in the filter at the same time. On the filter screen 9, the screening effect and efficiency are guaranteed; when the rotating rod 5 rotates, the rotating rod 5 drives the eccentric wheel 6 to rotate synchronously. During the rotation, the eccentric wheel 6 drives the right sliding cylinder 12 to slide back and forth on the sliding rod 11 through the transmission rod 13, and drives the filter frame 8 to move back and forth left and right through the telescopic cylinder 14, telescopic plate 15 and positioning plate 10. During the reciprocating movement of the filter frame 8, the wheat rolls and moves continuously on the filter screen 9. Under the screening of the filter screen 9, the wheat will fall to the bottom of the processing box 1, and impurities such as stones will remain in the filter frame 8.

[0022] When it is necessary to clean the stones and impurities in the filter frame 8, open the door 23 of the processing box 1. By pulling the handles 22 on both sides of the telescopic plate 15, the telescopic plate 15 will retract into the telescopic cylinder 14 against the elastic force of the spring 21. The telescopic plate 15 will disengage from the positioning groove 16. At this time, the filter frame 8 can be taken out from the U-shaped positioning frame 7. After cleaning, slide the filter frame 8 back into the U-shaped positioning frame 7, release the handles 22, and the telescopic plate 15 will extend again under the action of the spring 21 and insert into the positioning groove 16 of the positioning plate 10 to complete the installation. Close the door 23 to start working again and continue the screening work.
