Description

Technical Field

[0001] This utility model belongs to the field of grain processing technology, and in particular, it is a grain elevator that is easy to maintain. Background Technology

[0002] During rice processing, the grains need to be lifted from a low position to a high position multiple times. This process often uses a hoist. The principle is that the hoist lifts the grains entering from the inlet to a high position by driving the hopper inside the hoist, and then discharges them from the outlet. Most hoists now use an outer shell to protect the hoist and the transported grain. However, most outer shells are fixed by threaded connections or welding, making it difficult for personnel to quickly disassemble them. When the hopper containing the grain becomes stuck inside the outer shell due to equipment failure, personnel need to use tools to remove the bolts one by one or cut the outer shell to disassemble it and repair the internal equipment. This operation not only increases the workload of the workers, but also reduces the efficiency of hoist maintenance.

[0003] For example, there is a grain elevator with the Chinese announcement number CN218930814U, which "includes a base; a housing is provided on the base, a drawer is provided at the bottom of the housing, a drawer is movably connected inside the base, and a through groove is opened at the bottom of the housing, the through groove communicating with the base."

[0004] It is evident that the cited patent document presents the problem of difficulty in disassembling the outer casing for repairing the internal equipment. Utility Model Content

[0005] The purpose of this invention is to provide a grain elevator that is easy to maintain, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grain elevator that is easy to maintain, comprising a lower housing, an upper housing on the top surface of the lower housing, an inlet and an outlet for feeding grain on one side of the upper housing and the lower housing respectively, clamping rods symmetrically fixed on both sides of the upper housing via horizontal plates, and fixing boxes transversely provided on both sides of the lower housing, with symmetrical through slots inside the fixing boxes, both through slots extending to the top surface of the fixing boxes, the bottom ends of the two clamping rods extending into the inner cavity of the through slots and fixed with conical blocks, a threaded shaft on the inner sidewall of the through slot, one end of the threaded shaft extending to one side of the fixing box and fixed with a knob, and a clamping block rotatably connected to the other end of the threaded shaft, with a groove on one side of the clamping block adapted to the clamping rod.

[0007] Preferably, the locking block is positioned above the conical block, and slides are provided on both sides of the inner wall of the through groove.

[0008] Preferably, both sides of the card block are provided with sliders adapted to slide along the slide rail, and the top surface of the lower housing is provided with multiple vertical grooves.

[0009] Preferably, the bottom surface of the upper housing is fixed with a plurality of vertical rods, and the plurality of vertical grooves and vertical rods are slidably adapted to each other.

[0010] Preferably, a rectangular block is fixed on one side of the lower housing, and a connecting frame is provided on one side of the lower housing above the rectangular block.

[0011] Preferably, the two ends of the connecting frame are fixedly connected to one side of the two fixed boxes respectively, and the top surface of the rectangular block is rotatably connected with a threaded rod.

[0012] Preferably, the top end of the threaded rod extends through to the top of the connecting frame, and the connecting frame and the threaded rod are threadedly connected.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This easily maintainable grain elevator uses a locking block and groove design to fix the conical block and vertical rod, thereby securing the upper housing connected to the locking rod to the top surface of the lower housing. The threaded shaft allows the locking block to move, thus removing the locking block and groove from fixing the conical block and locking rod. This eliminates the need for fixing between the upper and lower housings, facilitating maintenance of the elevator with internal malfunctions. It reduces the need to use tools to sequentially cut bolts or the outer casing during maintenance, improving the efficiency of elevator maintenance.

[0015] The vertical groove and vertical rod design improves the stability of the connection between the lower and upper housings, while the threaded rod and connecting bracket allow the two fixing boxes to move upwards, enabling the locking block to abut against the top surface of the conical block, thus also improving the stability of the fixing.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 5 The grain elevator shown includes a lower housing 1, and the elevator equipment can be installed inside the lower housing 1. The top surface of the lower housing 1 is provided with an upper housing 2, which can enclose other equipment of the elevator. One side of the upper housing 2 and the lower housing 1 are respectively provided with an inlet and an outlet for feeding grain. The grain is fed into the lower housing 1 through the inlet, and the existing elevator drive structure inside drives the grain to move upward and discharge the grain through the outlet.

[0028] Both sides of the upper housing 2 are symmetrically fixed with locking rods 3 via horizontal plates. The bottom ends of the locking rods 3 extend to the bottom of the upper housing 2. Both sides of the lower housing 1 are horizontally provided with fixing boxes 4. The interior of the fixing boxes 4 is symmetrically provided with through slots 5. Both through slots 5 extend to the top surface of the fixing boxes 4. Both through slots 5 are symmetrically arranged with the two locking rods 3. When the upper housing 2 moves downward, the upper housing 2 will drive the locking rods 3 to move downward synchronously. After the upper housing 2 abuts against the top surface of the lower housing 1, the locking rods 3 can enter the through slots 5.

[0029] The bottom ends of the two locking rods 3 extend into the inner cavity of the through groove 5 and are fixed with tapered blocks 6. The inner wall of the through groove 5 is provided with a threaded shaft 8. One end of the threaded shaft 8 passes through to one side of the fixed box 4 and is fixed with a knob. The threaded shaft 8 is threadedly connected to the through hole of the fixed box 4 through which the threaded shaft 8 passes. The other end of the threaded shaft 8 is rotatably connected to a locking block 7. The locking block 7 is located above the tapered block 6. One side of the locking block 7 has a groove 9 that matches the locking rod 3. When the upper housing 2 abuts against the lower housing 1, the locking rod 3 will drive the tapered block 6 into the inner cavity of the through groove 5. At this time, the knob is rotated, which drives the threaded shaft 8 to move along the thread, thereby driving the locking block 7 to move toward the locking rod 3, and allowing the locking rod 3 to enter the groove 9 on one side of the locking block 7. When the locking rod 3 enters the groove 9... After the upper housing 2 is fixed to the top of the lower housing 1, the locking block 7 will be positioned above the conical block 6. Through the self-locking of the thread, the position of the conical block 6 can be limited, thereby limiting the position of the locking rod 3. Conversely, by rotating the knob in the opposite direction, the locking block 7 can be moved in the opposite direction through the threaded shaft 8, allowing the locking rod 3 to disengage from the groove 9 and the locking block 7 to be removed from above the conical block 6. This cancels the fixation of the conical block 6 and the upper housing 2 to the lower housing 1, thus facilitating installation and disassembly. It also allows for the repair of hoisting equipment with internal malfunctions in the upper housing 2 and lower housing 1, reducing the need to use tools to sequentially cut bolts or the outer shell during hoisting equipment repair, and improving the efficiency of hoisting equipment repair.

[0030] The top surface of the lower housing 1 is provided with multiple vertical grooves 13, and the bottom surface of the upper housing 2 is fixed with multiple vertical rods 14. The multiple vertical grooves 13 and the vertical rods 14 are slidably adapted to each other. When the upper housing 2 is against the top surface of the lower housing 1, the multiple vertical rods 14 are first allowed to enter the multiple vertical grooves 13, and then the upper housing 2 is moved downward so that the upper housing 2 is against the lower housing 1. The multiple vertical grooves 13 and the vertical rods 14 improve the stability of the installation between the lower housing 1 and the upper housing 2.

[0031] A rectangular block 15 is fixedly mounted on one side of the lower housing 1. A connecting frame 16 is located on one side of the lower housing 1 and above the rectangular block 15. The two ends of the connecting frame 16 are fixedly connected to one side of each of the two fixed boxes 4. A threaded rod 17 is rotatably connected to the top surface of the rectangular block 15. The top end of the threaded rod 17 extends through to the top of the connecting frame 16. The connecting frame 16 and the threaded rod 17 are threaded together. A handle is fixedly mounted on the top end of the threaded rod 17. By rotating the handle, the threaded rod 17 can be rotated. When the connecting frame 16 moves downward, the connecting frame 16 will move the two fixed boxes 4 downward. Since the two fixed boxes 4 need to be moved downward after the conical block 6 is fixed in the cavity of the through groove 5, the fixed box 4 will move downward at the same time as the fixed box 4 moves downward, so that the locking block 7 can abut against the top surface of the conical block 6 and apply downward pressure. This will prevent the locking block 7 and the conical block 6 from having a gap, thereby preventing the upper housing 2 from shaking within the range of motion of the gap, and also improving the stability of the lower housing 1 and the upper housing 2.

[0032] The lower housing 1 has symmetrically provided sliding grooves on both sides, and each of the two fixed boxes 4 has a vertical block that matches the sliding groove on one side. The inner cavity of the sliding groove and the top surface of the vertical block are respectively provided with a sliding rod and a sliding hole. When the fixed box 4 moves longitudinally, it will drive the vertical block to move longitudinally in the inner cavity of the sliding groove. The setting of the sliding rod and the sliding hole can improve the stability of the fixed box 4 when it moves longitudinally.

[0033] The inner walls of both sides of the through groove 5 are provided with slides 11, and the two sides of the locking block 7 are provided with sliders 12 that are adapted to slide along the slides 11. When the threaded shaft 8 drives the locking block 7 to move, the locking block 7 will drive the two sliders 12 to move in the inner cavity of the two slides 11, which can limit the movement of the locking block 7. The inner walls of the two slides 11 and one side of the two sliders 12 are also provided with slide rods and slide holes, which improves the stability of the movement of the locking block 7. The inner wall of the through groove 5 is provided with a locking groove 10. When the threaded shaft 8 drives the locking block 7 to move and the locking rod 3 enters the inner cavity of the groove 9, one side of the locking block 7 will enter the two locking grooves 10, which can restrict the locking block 7 through the rectangular grooves, thereby improving the restriction effect of the locking block 7 on the conical block 6.

[0034] Working principle:

[0035] This easily maintainable grain elevator feeds grain into the lower housing 1 through the inlet, and the existing elevator drive structure moves the grain upwards and discharges it through the outlet. When the elevator malfunctions due to grain blockage or other reasons, rotating the knob moves the locking block 7 via the threaded shaft 8, allowing the locking rod 3 to disengage from the groove 9 on one side of the locking block 7. When the locking block 7 moves away from the top of the conical block 6, the fixing of the conical block 6 is released. At this time, the upper housing 2 moves upwards, allowing the upper housing 2 to move upwards via the cross plate. The moving lever 3 moves upward, allowing it to be removed from the fixed box 4. Simultaneously, the upper housing 2 moves the vertical rod 14, allowing it to be removed from the inner cavity of the vertical groove 13. Once the lever 3 and the vertical rod 14 are removed from the inner cavity of the fixed box 4, the upper housing 2 can detach from the lower housing 1, exposing the equipment inside the upper housing 2. This allows for maintenance of the hoist equipment, reducing the need to use tools to sequentially cut bolts or the outer shell during maintenance and improving the efficiency of hoist equipment maintenance.
