Description

Technical Field

[0001] This utility model relates to the field of flour conveying technology, and more specifically, to a conveying device for flour processing. Background Technology

[0002] Flour is a powdery substance made from wheat and is loved by people in most parts of northern China. There are many kinds of food made from flour, with a wide variety of styles and flavors. According to the amount of protein in flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. In the process of flour processing, a conveying device is needed to transport the flour to the corresponding flour collection box.

[0003] A search revealed that Chinese utility model patent application number CN202221858467.6 discloses a conveying device for flour processing, including a mixing box and a conveying frame. A flour-beating device is fixedly connected to the upper middle part of the mixing box, and a flour hopper is fixedly connected to the upper left part of the mixing box. A dispensing mechanism is fixedly connected to the lower end of the mixing box. The end of the mixing box near the dispensing mechanism is fixedly connected to the conveying frame. The dispensing mechanism is located on the upper side of the conveying frame. A partition is fixedly connected to the middle of the lower inner wall of the conveying frame. The conveying frame is divided into two conveying compartments by the partition. A pushing mechanism is fixedly connected to the left end of the conveying frame. The output end of the pushing mechanism passes through the upper left part of the conveying frame and is slidably connected to the partition.

[0004] When in use, the threaded conveyor is started, allowing flour to fall from the two feed branch pipes under the mixing tank of the threaded conveyor into the two conveying compartments on the conveying frame below. This prevents the flour from sticking to the openings of the two feed branch pipes, thus greatly improving the flour feeding and conveying speed. The cylinder is activated by the external control system, which pushes the slider to slide and connect with the partition plate. Since the push plates connected to the front and rear ends of the slider are located in the two conveying compartments respectively, the cylinder can push the two push plates to push the flour in the two conveying compartments. The flour can be pushed to the two feed slide rails and then slide into the receiving box. During the process of the flour falling from the feed branch pipe into the conveying compartment and from the feed slide rail into the receiving box, because the flour is powdery and the particles are very fine, it is easy to scatter, affecting the surrounding environment and causing flour waste. In addition, the flour that slides from the feed track into the receiving box will fall into a localized area inside the receiving box, making it difficult to disperse the flour inside the receiving box.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a conveying device for flour processing, which has the following advantages:

[0018] 1. The lifting plate, threaded conveyor, and sealing cover are moved downward by the electric cylinder, so that the sealing cover covers the top of the receiving box. The threaded conveyor transports the flour into the inside of the receiving box. Since the sealing cover is on top of the receiving box, the flour is prevented from scattering everywhere during the process of falling into the receiving box, thus avoiding the impact of flour on the surrounding environment and preventing flour waste.

[0019] 2. By pushing and pulling the connecting plate, two first sliding rods, sliding plate and multiple push panels move, the flour inside the receiving box is pushed to the sides of the receiving box by the movement of multiple push panels, so as to avoid the flour accumulating in one place inside the receiving box and make it easier to disperse the flour inside the receiving box.

[0020] 3. As flour continuously falls into the receiving box, the air inside the receiving box is discharged through the vent pipe. The filter screen prevents the flour from scattering. By pulling the second slide rod upward and then releasing it, the compression spring pushes the rubber column and the second slide rod downward. The rubber column taps the filter screen, causing it to vibrate and shake off the flour, thus preventing the filter screen from clogging. Attached Figure Description

[0030] Please see Figures 1-5 A flour processing conveying device includes a mixing tank 1, a receiving box 2, and a threaded conveyor 3. The bottom end of the mixing tank 1 is connected to a first discharge pipe 4, and a second discharge pipe 5 is slidably and sealed to the outside of the first discharge pipe 4. The inlet end of the threaded conveyor 3 is connected to the bottom end of the second discharge pipe 5. An electric cylinder 6 is fixedly connected to the bottom end of the mixing tank 1, and a lifting plate 7 is fixedly connected to the bottom end of the electric cylinder 6. Four vertical rods 8 are fixedly connected to the lifting plate 7, and the four vertical rods 8 are slidably engaged with the mixing tank 1. The threaded conveyor 3 is fixedly connected to the top end of the lifting plate 7, and a sealing cover 9 is fixedly connected to the discharge end of the threaded conveyor 3. The receiving box 2 is placed below the sealing cover 9, and the sealing cover 9 covers the receiving box 2. A sealing gasket 10 is fixedly connected to the bottom end of the sealing cover 9.

[0031] Specifically, the electric cylinder 6 pushes the lifting plate 7, the threaded conveyor 3, and the sealing cover 9 downwards, so that the sealing cover 9 covers the top of the receiving box 2. The threaded conveyor 3 transports the flour into the receiving box 2. Since the sealing cover 9 covers the top of the receiving box 2, the flour is prevented from scattering everywhere during the process of falling into the receiving box 2, thus preventing the flour from flying into the surrounding environment and causing environmental impact, and also preventing the waste of flour.

[0032] Please see Figure 4 The sealing cover 9 has a sliding plate 11 inside, and multiple push panels 12 are fixedly connected to the bottom of the sliding plate 11. Two first sliding rods 13 are fixedly connected to the side of the sliding plate 11. Both first sliding rods 13 slide in cooperation with the sealing cover 9. A connecting plate 14 is fixedly connected to the end of the two first sliding rods 13 that extends to the outside of the sealing cover 9, so as to facilitate the dispersion and pushing of the flour inside the receiving box 2. A push-pull handle 15 is fixedly connected to the side of the connecting plate 14, so as to facilitate the pushing and pulling of the sliding plate 11. Two fixing rods 16 are fixedly connected inside the sealing cover 9. Both fixing rods 16 slide in cooperation with the sliding plate 11, so as to ensure that the sliding plate 11 slides stably inside the sealing cover 9. Two observation ports 17 are provided on the sealing cover 9. A transparent plate 18 is installed inside the two observation ports 17, so as to facilitate the observation of the inside of the receiving box 2. A wiping cloth 19 is fixedly connected to the top of the sliding plate 11, so as to facilitate the wiping of the surface of the transparent plate 18.

[0033] Specifically, by pushing and pulling 15, the connecting plate 14, the two first sliding rods 13, the sliding plate 11 and the multiple push panels 12 are moved. The multiple push panels 12 move to push the flour inside the receiving box 2 to the periphery of the receiving box 2, so as to prevent the flour from accumulating in one place inside the receiving box 2 and make it easier to disperse the flour inside the receiving box 2. During the sliding process, the sliding plate 11 causes the wiping cloth 19 to wipe the transparent plate 18, so that people can observe the inside of the receiving box 2 through the transparent plate 18.

[0034] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 A vent pipe 20 is provided on the sealing cover 9. A filter screen 21 is fixedly connected inside the vent pipe 20. A fixing frame 22 is fixedly connected to the top of the vent pipe 20. A second slide rod 23 is slidably arranged on the fixing frame 22. A rubber column 24 is fixedly connected to the bottom of the second slide rod 23. A compression spring 25 is provided between the rubber column 24 and the fixing frame 22. The compression spring 25 is sleeved on the outside of the second slide rod 23. A lifting plate 26 is fixedly connected to the top of the second slide rod 23 to facilitate tapping the filter screen 21 and prevent the filter screen 21 from becoming clogged.

[0035] Specifically, as the flour continuously falls into the receiving box 2, the air inside the receiving box 2 is discharged through the vent pipe 20. The filter screen 21 prevents the flour from scattering. By pulling the second slide bar 23 upward and then releasing the second slide bar 23, the compression spring 25 pushes the rubber column 24 and the second slide bar 23 downward. The rubber column 24 taps the filter screen 21, causing the filter screen 21 to vibrate and shake off the flour on the filter screen 21, thus preventing the filter screen 21 from becoming clogged.

[0036] In summary, when using the overall equipment:

[0037] Place the receiving box 2 below the sealing cover 9. Use the electric cylinder 6 to push the lifting plate 7, the threaded conveyor 3, and the sealing cover 9 downwards, so that the sealing cover 9 covers the top of the receiving box 2. The flour inside the mixing tank 1 falls to the threaded conveyor 3 through the first discharge pipe 4 and the second discharge pipe 5. The threaded conveyor 3 transports the flour into the receiving box 2. The inside of the receiving box 2 can be observed through the transparent plate 18. When the flour reaches the top of the receiving box 2, the push-pull handle 15 drives the connecting plate 14, the two first slide rods 13, the slide plate 11, and the multiple push panels 12 to move. The multiple push panels 12 move to push the flour inside the receiving box 2 to the sides of the receiving box 2.
