Description

Technical Field

[0001] The utility model belongs to the technical field of the application of removing impurities from corncobs, and particularly relates to a corncob cleaning machine. Background Art

[0002] The corncob is the core of the corn cob after threshing. With the rapid development of science and technology, the corncob has gradually developed from traditional fuel to industrial, agricultural, livestock, and domestic directions. For example, in the industrial aspect, the corncob can be used to extract heavy metals, make fillers for glue or paste, manufacture packaging materials and gunpowder, and increase the friction of tires as a rubber additive; in the agricultural aspect, it can be used for growing edible fungi; in the livestock aspect, the corncob can be used as animal feed and also as a carrier for vitamins and seasonings in the feed industry; in the domestic aspect, the corncob can be used to extract maltose, and can also be used as a dry cleaner and lubricant, and use its strong adsorption capacity to clean clothes and machines, etc.

[0003] However, the above applications of corncobs require the corncobs to be free of impurities. During the harvesting and threshing of corn cobs, the corncobs will be doped with certain iron filings, dust, broken cores and other impurities. At the same time, the corncob may also have ear husks (i.e., a layer of skin outside the corn cob). The existence of these impurities affects the later use of the corncob and needs to be removed. The existing corncob cleaning machines, such as a corncob dust and impurity cleaning machine disclosed by the State Intellectual Property Office [Patent No.: CN201821815721.8], use a vibrating method to remove impurities such as particles and dust, but its solution does not consider the problem of ear husks. Therefore, it cannot be cleaned cleanly and requires secondary cleaning, resulting in high labor intensity and high cleaning cost. Summary of the Utility Model

[0004] Aiming at the technical problems existing in the corncob cleaning machine, the utility model provides a corncob cleaning machine with reasonable design, simple structure, convenient processing and capable of effectively removing impurities such as iron filings, dust, broken cores and ear husks.

[0016] 1. The utility model provides a corn cob cleaning machine. By using the iron removal device arranged on the feeding channel, when the corn cobs fall, they approach or contact the iron removal device to complete the removal of iron filings. The auger spiral blades arranged at both ends of the rotating shaft are used to complete the movement of the corn cobs in the cleaning cylinder. The sliders arranged in the middle of the rotating shaft are used to complete the backward pushing, shaking of the corn cobs and the tearing of the husks, so that they are dispersed under the action of centrifugal force, and thus the sundries are sucked by negative pressure. At the same time, with the setting of the hook plates, the husks are hooked, and under the restriction of the cleaning cylinder on the corn cobs, the separation of the corn cobs from the husks is realized and the husks are brought into the impurity suction box, and finally are extracted by the impurity suction fan together with the sundries.

[0026] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0028] Embodiment 1, as Figures 1 to 6 shown, the purpose of this embodiment is to provide a cleaning machine that can complete the removal of various sundries from corncobs at one time. To this end, the corncob cleaning machine provided in this embodiment includes a frame 1 and a feed hopper 11 provided on the frame 1. The main purpose of the feed hopper 11 is to place corncobs. A feed channel 3 is connected below the feed hopper 11. When directly connected to a corn threshing machine, the core outlet of the corn threshing machine can be directly connected to the feed channel 3. In this way, the setting of the feed hopper 11 can be omitted. An iron removal device is provided in the feed channel 3. The iron removal device can be a magnetic substance such as an iron removal rod or an iron removal roller 31. In this way, when the corncobs with sundries pass through the feed channel 3, other iron-containing sundries such as iron filings will be adsorbed by the iron removal device. In this embodiment, in order to provide a longer service life and avoid frequent cleaning, at the same time, in order to facilitate the falling of corncobs and avoid blockage in the feed channel 3, the iron removal device is an iron removal roller 31 rotatably provided in the feed channel 3. Due to the rotatable setting of the iron removal roller 31, the corncobs are not easily piled up. At the same time, the rotatably provided iron removal roller 31 is also beneficial to fully utilize the side wall of the iron removal roller 31 and reduce the cleaning cycle. In this embodiment, in order to facilitate the cleaning of the iron filings on the iron removal roller 31, an iron removal port is opened on the feed channel 3. In order to prevent the corncobs from falling from the iron removal port, the iron removal port is normally closed by an iron removal port baffle 32 at other times when cleaning the iron filings on the iron removal roller 31.

[0029] Similarly, in order to prevent the corncobs from blocking the feed channel 3, in this embodiment, a conveyor belt 2 is provided below the feed hopper 11, and the feed channel 3 is provided at one end of the conveyor belt 2. The purpose of this setting is not only to prevent the blockage of the feed channel 3, but also to facilitate the increase in the volume of the feed hopper 11. In this way, when placing corncobs, large equipment such as a forklift can be used for feeding to improve the feeding efficiency.

[0030] Considering that there are still dust, broken cores and bracts after the removal of iron filings, in order to remove them, a cleaning cylinder 4 is connected below the feeding channel 3. The cleaning cylinder 4 is placed horizontally, that is, its axis is horizontally arranged. A rotating shaft 5 is arranged in the cleaning cylinder 4. The rotating shaft 5 is rotationally arranged along the axial direction of the cleaning cylinder 4 in the cleaning cylinder 4. The feeding channel 3 is arranged at one end close to the cleaning cylinder 4. Auger spiral blades 51 are arranged at both ends of the rotating shaft 5. The main purpose of the auger spiral blades 51 is to convey the corn cobs. For this reason, the spiral modes of the auger spiral blades 51 at both ends are the same.

[0031] Considering that the piled-up corn cobs are not convenient to remove, for this reason, in this embodiment, a paddle 52 is arranged in the middle of the rotating shaft 5. The distance where the paddle 52 is located should account for half of the length of the cleaning cylinder 4, and the paddle 52 is evenly distributed on the rotating shaft 5. The main purpose of the paddle 52 is to stir the corn cobs, so as to use the centrifugal force generated by the rotating rotating shaft 5 to throw up the corn cobs and other sundries. For this reason, in this embodiment, the paddle 52 is arranged in a rectangular sheet shape. At the same time, a impurity extraction box 6 is arranged above the cleaning cylinder 4. One side of the impurity extraction box 6 is connected with an impurity extraction fan 61. In this way, only by setting holes on the cleaning cylinder 4, the dust and broken cores can be extracted by using the negative pressure generated by the impurity extraction fan in the impurity extraction box, and then discharged through the impurity extraction fan 61. At the same time, the rectangular sheet structure can use its edges and corners to break the bracts, so as to separate the bracts from the corn cobs. In order to facilitate better use of the wind power of the impurity extraction fan, the size of the wind power can be adjusted by setting a valve on the pipeline between the impurity extraction fan 61 and the impurity extraction box 6.

[0032] Considering that under the action of centrifugal force and negative pressure, the bracts will block the holes on the cleaning cylinder 4 due to their size, for this reason, a rotating shaft 7 is arranged in the impurity extraction box 6. The rotating shaft 7 is also arranged along the axis of the cleaning cylinder 4. At the same time, it is also rotationally arranged in the impurity extraction box 6. A hook plate 71 is arranged on the rotating shaft 7. The hook plate 71 is integrally in a plate shape, but its side wall is in an arc-shaped hook shape. At the same time, the end of the hook plate 71 can extend into the cleaning cylinder 4. A through groove 41 for the hook plate 71 to pass through is arranged on the side wall of the cleaning cylinder 4. Since the bracts are attached to the inner wall of the cleaning cylinder 4, the end of the hook plate 71 will extend into the cleaning cylinder 4 through the through groove 41 and hook the bracts. Due to the limitation of the through groove 41 on the corn cobs, in this way, the rotation of the hook plate 71 only takes away the bracts, thus completely removing the bracts. In order to ensure the cleaning effect, the hook plates 71 are evenly distributed on the rotating shaft 7. It should be noted that the width of the through groove 41 should be less than the diameter of the corn cobs.

[0033] Of course, it is also necessary to convey the cleaned corn cobs out. For this reason, a core outlet is arranged at one end of the cleaning cylinder 4 away from the feeding channel 3.

[0034] Considering that the corncobs after cleaning need to be loaded whether they are stored, crushed or put into the next process, a climbing conveyor belt 8 is provided at the core outlet. In this way, the height is increased by the climbing conveyor belt 8, which is convenient for loading and storage.

[0035] Considering that there are some debris such as stones that cannot be pulled by the exhaust fan 61, it is not convenient to shake them due to the structural characteristics of the paddle 52. Therefore, they will accumulate at the bottom of the cleaning cylinder 4. In order to facilitate the removal of such debris, a debris discharge hole 42 is provided at the bottom of the cleaning cylinder 4. The debris discharge holes 42 are evenly distributed at the bottom of the cleaning cylinder 4. The size of the debris discharge hole 42 should be smaller than the corn cob with a particle size of 10 mm, so this type of corn cob has application value.

[0036] In order to prevent the debris from being piled up randomly from the debris outlet hole 42, a debris guide plate 43 is also provided at the bottom of the cleaning cylinder 4, and the debris guide plate 43 is arranged below the debris outlet hole 42. In this way, the discharge direction of the debris is consistent through the debris guide plate 43, making it more convenient to clean it later.

[0037] In order to facilitate the movement of the corn cob in the middle of the rotating shaft 5, in this embodiment, the paddle 52 is tiltedly arranged on the rotating shaft 5. In this way, it forms a conveying mode similar to the spiral blade 51 of the auger, pushing the corn cob to move in the centrifugal case.

[0038] In order to better promote the movement of the corn cob, in this embodiment, the paddles 52 are evenly distributed on the rotating shaft 5 along the spiral trajectory of the auger spiral blade 51. In this way, the corn cob can be moved better in accordance with the spiral trajectory of the auger spiral blade 51, thereby avoiding the occurrence of accumulation-type movement and ensuring the cleaning effect.

[0039] In order to improve the negative pressure effect, in this embodiment, a partition is provided in the impurity extraction box 6, which divides the impurity extraction box 6 into two chambers, each of which is connected to an impurity extraction fan 61. In this way, the wind force is improved while ensuring uniformity, thereby ensuring the impurity extraction effect. Of course, it can also be matched according to the size of different impurity extraction boxes 6 and the size of the impurity removal fan.

[0040] Through the above-mentioned arrangement, the iron filings, dust, broken cores and husks in the corn cobs can be removed at one time, thus avoiding secondary removal, improving work efficiency and reducing labor intensity.

[0041] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
