Description

Technical Field

[0001] This utility model belongs to the technical field of bucket elevators, specifically relating to a material return and crushing structure for a bucket elevator. Background Technology

[0002] Our company is a wholly state-owned enterprise, mainly engaged in grain purchase, storage, and processing. Grain processing involves cleaning, hulling, milling, color sorting, polishing, sorting, and packaging. Bucket elevators play a crucial role in the operation of each process in grain processing. Existing bucket elevators, such as CN 208120021 U, entitled "A Bucket Elevator", include a vertical barrel (1), a head (2) fixedly connected to the top of the barrel (1), and a tail (3) fixedly connected to the bottom of the barrel (1). The head (2) has a discharge port (21), and the tail (3) has a feed port (31). The barrel (1) includes a first barrel (13) and a second barrel (14) arranged side by side. The opposite ends of the first barrel (13) and the second barrel (14) are fixedly connected to the head (2) and the tail (3), respectively. The bucket elevator further includes a... The machine includes a drive wheel (4) installed in the head (2), a driven wheel (5) installed in the tail (3), a transmission belt (6) wound around the drive wheel (4) and the driven wheel (5), and multiple buckets (61) on the transmission belt (6). The transmission belt (6) passes through the first barrel (13) and the second barrel (14). Both the first barrel (13) and the second barrel (14) include a barrel body (11) and flanges (12) arranged at opposite ends of the barrel body (11) along the conveying direction. The barrel body (11) and the flanges (12) are integrally formed. The barrel body (11) is cylindrical, and the flanges (12) are welded to both ends of the barrel body (11). The machine further includes a reducing joint (7) fixed at opposite ends of the barrel (1). The reducing joint (7) is used to fix the flanges (12) at both ends to the corresponding head (2) or tail (3). It also includes a motor fixedly installed on the side wall of the machine head (2). The motor drives the drive wheel (4) to rotate through the transmission mechanism. The transmission belt (6) reciprocates around the drive wheel (4) and the driven wheel (5) under the drive of the drive wheel (4). In order to facilitate assembly during production and maintenance during use, the existing bucket elevator has a sufficient design gap between the running trajectory line of its outer end and the vertical plane of the partition when the bucket is vertically descending. The design gap is set so that when the bucket elevator is conveying rice, it will fall back to the tail of the machine through the design gap. The falling rice will not only affect the conveying efficiency of rice, but also increase the broken rice rate (about 5%). Utility Model Content

[0003] Design objective: To avoid the shortcomings of the prior art, this paper designs a bucket elevator return and breakage reduction structure that can not only reduce the broken rice rate but also improve the rice conveying efficiency, without affecting the normal maintenance of the bucket elevator, and with good performance.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The bucket elevator has a head at the top of its vertical drum and a tail at the bottom. The head contains a drive wheel located directly above the vertical drum, and the tail contains a driven wheel located directly below the vertical drum. A drive belt connects the drive wheel and the driven wheel, passing through the drum body. Multiple buckets are mounted on the drive belt. The lower end of the head has a drum inlet and a discharge port that connect to the upper end of the vertical drum. After the drum inlet and the upper end of the vertical drum are fixedly connected, the discharge port is located outside the vertical drum, and its height is lower than that of the drive wheel. The chamber inside the head is divided into two chambers by a partition. The drum inlet communicates with chamber one. The discharge port is connected to the second chamber. The upper part of the partition is provided with a square through hole, one end of which is connected to the first chamber and the other end of which is connected to the second chamber. The partition wall on one side of the first chamber is a vertical surface and the partition wall on the other side of the second chamber is an inclined surface. When the bucket moves vertically downward, there is a designed gap between the running trajectory line of its outer end and the vertical surface of the partition. The partition also includes a gap adjustment plate. The upper end of the gap adjustment plate is provided with two strip-shaped through holes that pass through the upper and lower end faces of the gap adjustment plate. The inclined surface of the partition is provided with two threaded rods. The design of fixing the gap adjustment plate by two nuts after the two strip-shaped through holes are inserted and engaged with the corresponding threaded rods is one of the technical features of this utility model.The purpose of this design is as follows: the top of the vertical barrel of the bucket elevator is equipped with a head, and the bottom of the vertical barrel is equipped with a tail. The head contains a drive wheel located directly above the vertical barrel, and the tail contains a driven wheel located directly below the vertical barrel. A drive belt connects the drive wheel and the driven wheel, passing through the barrel body of the vertical barrel. Multiple buckets are mounted on the drive belt. The lower end face of the head has a barrel interface and a discharge port that connect to the upper port of the vertical barrel. The barrel interface of the head... After being fixedly connected to the upper port of the vertical barrel, the discharge port is located on the outside of the vertical barrel. The height of the discharge port is lower than the height of the drive wheel. The chamber inside the machine head is divided into chamber one and chamber two by a partition. The barrel inlet communicates with chamber one, and the discharge port communicates with chamber two. The upper part of the partition has a square through hole, one end of which communicates with chamber one and the other end with chamber two. The partition wall on the side of chamber one is a vertical surface, and the partition wall on the side of chamber two is an inclined surface. When the bucket descends vertically... A design gap is left between the running trajectory line of the outer end and the vertical surface of the partition, and a gap adjustment plate is also included. The upper end face of the gap adjustment plate has two strip-shaped through holes that pass through both the upper and lower end faces of the gap adjustment plate. Two threaded rods are provided on the inclined surface of the partition. After the gap adjustment plate is placed on the inclined surface of the partition and the two strip-shaped through holes are inserted and engaged with the corresponding threaded rods, it is fixedly connected by two nuts. The length of the strip-shaped through hole is greater than the width of the strip-shaped through hole, and the diameter of the threaded rod matches the width of the strip-shaped through hole. The diameter of the mother is larger than the width of the strip-shaped through hole. When the bucket elevator is working, the operator loosens the two nuts, then moves the gap adjustment plate as needed to reduce the design gap. After adjustment, the operator tightens the two nuts. The reduced design gap will effectively reduce the amount of rice falling back, which can not only reduce the broken rice rate, but also improve the conveying efficiency of rice. In addition, when maintenance is required, the operator only needs to loosen the two nuts and then move the gap adjustment plate back. At this time, the design gap is restored to the factory setting, which is convenient for maintenance.

[0006] 2. The upper end face of the tail section is provided with a barrel interface and a feed inlet that connect to the lower port of the vertical barrel. After the barrel interface at the tail section and the lower port of the vertical barrel are fixedly connected, the feed inlet is located on the outside of the vertical barrel. The height of the feed inlet is higher than the height of the driven wheel. The design of the feed inlet and the discharge outlet located on both sides of the vertical barrel is the second technical feature of this utility model. The purpose of this design is that the upper end face of the tail section is provided with a barrel interface and a feed inlet that connect to the lower port of the vertical barrel. After the barrel interface at the tail section and the lower port of the vertical barrel are fixedly connected, the feed inlet is located on the outside of the vertical barrel. The height of the feed inlet is higher than the height of the driven wheel. The feed inlet and the discharge outlet are located on both sides of the vertical barrel, which facilitates the use of a bucket elevator for material return and crushing structure.

[0007] 3. The design of the nut as a ram's horn nut is the third technical feature of this utility model. The purpose of this design is that the nut is a ram's horn nut, so that the user can manually loosen or tighten the ram's horn nut, thereby improving the performance of the bucket elevator's material return and crushing structure.

[0008] 4. The design of the discharge port having a guide funnel located at the lower end of the machine head is the fourth technical feature of this utility model.
