A color sorting device for corn seed processing and screening

Abstract

This utility model relates to the field of corn seed processing technology, specifically a color sorting device for corn seed processing and screening. It includes a base, a color sorter mounted on top of the base, a conveying pipe fixedly connected to the output end of the color sorter, a storage bin placed in a groove in the base, and a corrugated pipe mechanism for conveying corn seeds into the storage bin on the outside of the conveying pipe. When conveying corn seeds, the corrugated pipe is straightened and extended by a hydraulic cylinder to increase its effective length, adapting to deeper storage bins or increasing the descent stroke. When the storage bin needs to be replaced or operation is stopped, the corrugated pipe is folded and shortened. This mechanism replaces the original flexible hose structure. Furthermore, the hydraulic cylinder provides a controllable and appropriately forceful pushing and pulling action, avoiding excessive tightening or improper force by the operator. The structural characteristics of the corrugated pipe ensure that it is not easily flattened when bent.

Description

Technical Field

[0001] This utility model relates to the field of corn seed processing technology, specifically a color sorting device for screening corn seeds. Background Technology

[0002] Before corn seeds are processed and packaged, they need to be color sorted to remove bad seeds. This is done using a color sorter, which is a device that automatically sorts out discolored particles from granular materials based on the differences in the optical properties of the materials using photoelectric detection technology. It is used in the fields of bulk materials or packaging industrial products, food quality testing and grading.

[0003] As described in the patent with publication number CN217528307U, by pulling down the collar, the hose is stretched and the collar is installed on the outside of the storage hopper. By rotating the limiting rod, the limiting rod and the collar rotate threadedly, and one end of the limiting rod abuts against the outside of the storage hopper. This allows the collar to fit tightly against the outside of the storage hopper, preventing the corn seeds from overflowing or popping out of the receiving hopper during transportation.

[0004] However, when using this structure, in order to ensure that there is no leakage, the operator may overtighten the limiting rod. Long-term excessive compression will cause the hose to crack or be damaged, shortening its service life. Furthermore, if too much force is applied to the top of the limiting rod, it may scratch or dent the outer wall of the storage hopper. Therefore, a color sorting device for corn seed processing and screening is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a color sorting device for corn seed processing and screening, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a color sorting device for processing and screening corn seeds, comprising a base, a color sorter being provided on the top of the base, a conveying pipe being fixedly connected to the output end of the color sorter, a storage bin being placed in the groove of the base, and a corrugated pipe mechanism for conveying corn seeds into the storage bin being provided on the outside of the conveying pipe.

[0007] The bellows mechanism includes a bellows, a hydraulic cylinder, and a connecting ring. The bellows is detachably connected to the conveying pipe. The output end of the hydraulic cylinder is used to drive the bellows to unfold or fold through the connecting ring.

[0008] The bottom side of the connecting ring is provided with an airbag ring mechanism for docking the corrugated pipe with the storage tank.

[0009] Preferably, the bellows mechanism further includes a fixed flange and a connecting flange;

[0010] The fixed flange is fixedly assembled to the output end of the conveying pipe, and the connecting flange is fixedly assembled to the input end of the bellows. The fixed flange and the connecting flange are connected by bolts.

[0011] Preferably, the connecting ring is fixedly connected to the output end of the bellows, and the output end of the hydraulic cylinder is fixedly connected to the connecting ring.

[0012] Preferably, the output end of the hydraulic cylinder after being energized is used to drive the connecting ring to move up and down, and the bellows is detached and installed at the output end of the conveying pipe through the fixed flange and the connecting flange.

[0013] Preferably, the airbag ring mechanism includes an annular frame, an air pump, an airbag ring, a sealing ring, and an annular groove;

[0014] The annular frame is fixedly connected to the bottom side of the connecting ring, the air pump is fixedly installed on the outside of the annular frame, the airbag ring is disposed on the inside of the annular frame, the sealing ring is disposed on the inside of the airbag ring, and the annular groove is formed on the surface of the storage barrel.

[0015] Preferably, the air pump is connected to the mating end of the airbag ring, and the air pump, when energized, is used to drive the airbag ring to inflate.

[0016] Preferably, the inflated airbag ring is in contact with the surface of the storage tank and is used to lock the position of the ring frame.

[0017] Preferably, the annular groove is used for the sealing ring to engage inside it, and the engaged state of the sealing ring and the annular groove is used to improve the stability of the locking of the annular frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: When conveying corn seeds, the corrugated pipe mechanism is driven by a hydraulic cylinder to straighten and extend its effective length to accommodate deeper storage bins or increase the descent stroke. When it is necessary to replace the storage bin or stop the operation, the corrugated pipe is driven to fold and shorten. This mechanism replaces the original flexible hose structure. Furthermore, the hydraulic cylinder provides a controllable and appropriately forceful push-pull action, avoiding the operator's excessive tightening or improper force. The structural characteristics of the corrugated pipe ensure that it is not easily flattened when bent, ensuring the continuity of corn seed flow.

[0019] This airbag ring mechanism allows the connecting ring to descend to the appropriate position, after which an air pump inflates the airbag ring, causing it to expand and fit tightly against the outer wall of the storage hopper. Simultaneously, a sealing ring is embedded in the annular groove, forming a stable and sealed connection channel. The sorted seeds then smoothly enter the storage hopper through the conveying pipe and corrugated pipe. Furthermore, the expansion of the airbag ring can adapt to any unevenness or slight diameter differences that may exist on the outer wall of the storage hopper, ensuring the reliability of the seal and preventing dust and seed leakage. Moreover, the inflation pressure is uniform and flexible, avoiding the problems of scratching and denting the outer wall of the storage hopper that may have been caused by excessive tightening of the limit rod in the original structure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution for a color sorting device for corn seed processing and screening: a color sorting device for corn seed processing and screening includes a base 1, a color sorter 2 is provided on the top of the base 1, a conveying pipe 3 is fixedly connected to the output end of the color sorter 2, a storage bucket 4 is placed in the groove of the base 1, and a corrugated pipe mechanism 5 for conveying corn seeds into the storage bucket 4 is provided on the outside of the conveying pipe 3.

[0027] The bellows mechanism 5 includes a bellows 503, a hydraulic cylinder 504 and a connecting ring 505. The bellows 503 is detachably connected to the conveying pipe 3. The output end of the hydraulic cylinder 504 is used to drive the bellows 503 to unfold or fold through the connecting ring 505.

[0028] The bottom side of the connecting ring 505 is provided with an airbag ring mechanism 6 for docking the corrugated pipe 503 with the storage tank 4.

[0029] Please refer to this carefully. Figure 2 The bellows mechanism 5 also includes a fixed flange 501 and a connecting flange 502;

[0030] The fixed flange 501 is fixedly mounted on the output end of the conveying pipe 3, and the connecting flange 502 is fixedly mounted on the input end of the bellows 503. The fixed flange 501 and the connecting flange 502 are connected by bolts.

[0031] In this embodiment, the bellows 503 is connected to the fixed flange 501 at the output end of the feed pipe 3 via bolts through the connecting flange 502 at its input end, thereby achieving a detachable and stable inlet end fixation.

[0032] Please refer to this carefully. Figure 2 The connecting ring 505 is fixedly connected to the output end of the bellows 503, and the output end of the hydraulic cylinder 504 is fixedly connected to the connecting ring 505.

[0033] In this embodiment: extending the output end of the hydraulic cylinder 504 in operation pushes the connecting ring 505 downward, straightening and extending the bellows 503 fixed thereto, thus extending its effective length.

[0034] Please refer to this carefully. Figure 2 The output end of the energized hydraulic cylinder 504 is used to drive the connecting ring 505 to move up and down, and the bellows 503 is detached and installed at the output end of the conveying pipe 3 through the fixed flange 501 and the connecting flange 502.

[0035] In this embodiment: the hydraulic cylinder 504 is activated by the control system, so that the output end of the hydraulic cylinder 504 in operation extends, which pushes the connecting ring 505 to move downward.

[0036] Please refer to this carefully. Figure 3 The airbag ring mechanism 6 includes an annular frame 601, an air pump 602, an airbag ring 603, a sealing ring 604, and an annular groove 605.

[0037] The ring frame 601 is fixedly connected to the bottom side of the connecting ring 505, the air pump 602 is fixedly installed on the outside of the ring frame 601, the airbag ring 603 is set on the inside of the ring frame 601, the sealing ring 604 is set on the inside of the airbag ring 603, and the annular groove 605 is opened on the surface of the storage tank 4.

[0038] In this embodiment: when the connecting ring 505 descends to the appropriate position, the air pump 602 starts and inflates the airbag ring 603, causing it to expand and fit tightly against the outer wall of the storage tank 4. At the same time, the sealing ring 604 is embedded in the annular groove 605 to form a stable and sealed connecting channel.

[0039] Please refer to this carefully. Figure 3 The air pump 602 is connected to the mating end of the airbag ring 603, and the air pump 602, when energized, is used to drive the airbag ring 603 to inflate.

[0040] In this embodiment: the air pump 602 is started by the control system, and the running air pump 602 fills the airbag ring 603 with gas, and the airbag ring 603 begins to expand.

[0041] Please refer to this carefully. Figure 3 The inflated airbag ring 603 is attached to the surface of the storage bucket 4 and is used to lock the position of the ring frame 601.

[0042] In this embodiment: the inflated airbag ring 603 generates uniform pressure inward, so the airbag ring 603 is tightly pressed against the outer wall of the storage tank 4.

[0043] Please refer to this carefully. Figure 4 The annular groove 605 is used for the sealing ring 604 to engage inside it, and the sealing ring 604 and the annular groove 605 in the engaged state are used to improve the stability of the locking of the annular frame 601.

[0044] In this embodiment, the interlocking mechanism between the sealing ring 604 and the annular groove 605 enhances the stability of the connection and prevents the connection from becoming loose due to vibration or shaking of the bellows 503 during transportation. The positioning of the sealing ring 604 by the annular groove 605 also ensures the accuracy of the sealing surface.

[0045] Working principle: Because the hose in the original structure is easily flattened when bent excessively, the seed flow is interrupted. At this time, the bellows 503 is connected to the fixed flange 501 at the output end of the conveying pipe 3 by bolts through the connecting flange 502 at its input end, which achieves a detachable and stable inlet end fixation. When the control system starts the hydraulic cylinder 504, the output end of the hydraulic cylinder 504 in the running state extends, which pushes the connecting ring 505 to move downward, straightening and extending the bellows 503 fixed to it, extending its effective length to adapt to a deeper storage tank 4 or increase the descent stroke. When it is necessary to replace the storage tank 4 or stop the operation, the hydraulic cylinder 504 retracts, pulling the connecting ring 505 upward, and at the same time the bellows 503 also folds and shortens under its own elasticity.

[0046] The bellows 503 is then extended downwards, bringing its output end connecting ring 505 close to the opening of the storage hopper 4. This causes the ring frame 601 to be fitted onto the outside of the storage hopper 4. Simultaneously, the control system activates the air pump 602, which inflates the air bladder ring 603. The inflated air bladder ring 603 generates uniform pressure, causing it to press tightly against the outer wall of the storage hopper 4. At the same time, the sealing ring 604 engages under pressure. Within the annular groove 605, the interlocking mechanism between the sealing ring 604 and the annular groove 605 forms a mechanical interlock, enhancing the stability of the connection and preventing the connection from loosening due to vibration or shaking of the bellows 503 during the conveying process. Subsequently, the sorted seeds smoothly enter the storage bin 4 through the conveying pipe 3 and the bellows 503. When the storage bin 4 is full, the air pump 602 depressurizes, the air bladder ring 603 contracts and releases its lock, and the hydraulic cylinder 504 retracts to lift the bellows 503, allowing the full bin to be removed and the empty bin to be replaced.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
