Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a lifting mechanism for a silo. Background Technology

[0002] In existing silo lifting mechanisms, lead screws are commonly used as transmission elements to drive the silo to move up and down. This mechanism is simple and effective, and can meet the needs of various warehousing and logistics scenarios. However, with prolonged use, lead screws inevitably experience wear, which not only reduces their transmission efficiency but may also lead to unstable operation of the mechanism or even malfunction. To address the wear problem of lead screws, traditionally, it is necessary to rely on staff to perform regular maintenance and upkeep. One of the most important tasks is to apply lubricating oil to the lead screw. The function of lubricating oil is to reduce friction between the lead screw and the nut, reduce the wear rate, and also help dissipate heat and prevent corrosion.

[0003] However, due to the busyness or negligence of the staff, it is easy to forget to lubricate the lead screw. Once lubrication is not timely, the wear of the lead screw will deteriorate rapidly, which will affect the performance and life of the entire lifting mechanism. Secondly, the process of applying lubricating oil also takes a considerable amount of time. The staff needs to carefully and evenly apply the lubricating oil to the surface of the lead screw to ensure that it can fully play its lubricating role. This process is not only tedious but also inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a material silo lifting mechanism to solve the problem of difficulty in applying lubricating oil to the lead screw mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hopper lifting mechanism includes: a hopper body with a horizontal plate on it, a lead screw rotatably mounted on the horizontal plate, a lifting plate threaded onto the lead screw; a pouring assembly mounted on the horizontal plate, comprising a placement tank on the horizontal plate, a placement groove inside the placement tank, a connector on the placement groove, and a sponge on the connector; the pouring assembly is used for lubricating the lead screw; and a replacement assembly mounted on the connector, comprising a limiting block on the connector, a connecting groove on the connector, and a fixing plate on the sponge; the replacement assembly is used for replacing the sponge.

[0007] Preferably, the irrigation assembly further includes a first T-shaped groove provided inside the placement groove, and a first T-shaped block provided on one side of the connector corresponding to the first T-shaped groove, the first T-shaped block being movably disposed within the first T-shaped groove.

[0008] Preferably, the top of the connector is provided with an elastic element, one end of which is disposed on the placement tank, one end of the connector penetrates through the placement tank, and the top of the placement tank is provided with a filling port.

[0009] Preferably, a fixing groove is provided on the side of the connector corresponding to the sponge, and the sponge is movably disposed in the fixing groove.

[0010] Preferably, the replacement component also includes connecting grooves provided on both sides of the fixing groove, and the fixing plate is movably disposed in the connecting groove.

[0011] Preferably, the bottom of the limiting block is provided with a second T-shaped block, and the connecting piece is provided with a second T-shaped groove corresponding to the second T-shaped block, and the second T-shaped block is movably disposed in the second T-shaped groove.

[0012] Preferably, three sets of springs are provided between the limiting block and the connecting member.

[0013] Preferably, a rubber cylinder is provided on the top of the limiting block, and the rubber cylinder is in contact with the lifting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The lifting plate squeezes the connector, causing it to move upwards. This allows one end of the sponge to be inside the placement groove, while the other end contacts the lead screw. This allows lubricating oil to flow evenly onto the lead screw through the four sets of sponges, thus providing uniform lubrication and protecting the lead screw. It also prevents workers from forgetting to lubricate the lead screw.

[0016] By pulling the limiting block, the fixing plate on the sponge can be limited, enabling quick replacement of the sponge. This also prevents uneven lubrication of the lead screw after the sponge is damaged due to prolonged use, thus avoiding a decrease in the working efficiency of the device due to sponge damage.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figure 1-7 As shown, this application provides a silo lifting mechanism, including: a silo body 1, a horizontal plate 3 on the silo body 1, a lead screw 2 rotatably mounted on the horizontal plate 3, a lifting plate 20 threadedly connected to the lead screw 2, a pouring assembly on the horizontal plate 3, the pouring assembly including a placement tank 4 mounted on the horizontal plate 3, a placement groove 11 inside the placement tank 4, a connector 8 mounted on the placement groove 11, and a sponge 12 mounted on the connector 8, the pouring assembly being used for lubrication of the lead screw 2.

[0028] Specifically, such as Figure 3 As shown, the irrigation assembly also includes a first T-shaped groove 9 provided inside the placement groove 11, and a first T-shaped block 10 provided on one side of the connector 8 corresponding to the first T-shaped groove 9. The first T-shaped block 10 is movably disposed in the first T-shaped groove 9. By the first T-shaped block 10 being inserted into the first T-shaped groove 9, the sliding of the connector 8 can be limited, so that the sliding direction of the connector 8 can remain consistent.

[0029] Specifically, such as Figure 4As shown, the top of the connector 8 is provided with an elastic element 7, one end of the elastic element 7 is provided on the placement tank 4, one end of the connector 8 passes through the placement tank 4, and the top of the placement tank 4 is provided with a filling port 5. The elastic force of the elastic element 7 can keep the connector 8 moving downward, which can prevent the lubricating oil from leaking accidentally.

[0030] Specifically, such as Figure 4 As shown, a fixing groove 6 is provided on one side of the connector 8 corresponding to the sponge 12. The sponge 12 is movably disposed in the fixing groove 6. The sponge 12 can carry the lubricating oil out from the placement groove 11 and apply the lubricating oil to the lead screw 2.

[0031] The connector 8 is provided with a replacement component, which includes a limiting block 13 on the connector 8, a connecting groove 17 on the connector 8, and a fixing plate 19 on the sponge 12. The replacement component is used to replace the sponge 12.

[0032] Specifically, such as Figure 6 As shown, the replacement component also includes connecting grooves 17 on both sides of the fixing groove 6. The fixing plate 19 is movably disposed in the connecting groove 17. By inserting the fixing plate 19 into the connecting groove 17, the initial positioning of the sponge 12 can be achieved, which facilitates the subsequent fixing of the sponge 12 by the limiting block 13.

[0033] Specifically, such as Figure 6 As shown, a second T-shaped block 14 is provided at the bottom of the limiting block 13, and a second T-shaped groove 16 is provided on the connector 8 corresponding to the second T-shaped block 14. The second T-shaped block 14 is movably disposed in the second T-shaped groove 16. The second T-shaped block 14 slides in the second T-shaped groove 16, so that the limiting block 13 can always slide in the same direction.

[0034] Specifically, such as Figure 6 As shown, three sets of springs 18 are provided between the limiting block 13 and the connecting piece 8. The elastic force of the springs 18 can keep the limiting block 13 in a limiting position on the sponge 12 after the sponge 12 is installed.

[0035] Specifically, such as Figure 6 As shown, a rubber cylinder 15 is provided on the top of the limiting block 13. The rubber cylinder 15 contacts the lifting plate 20. By pulling the rubber cylinder 15, it is convenient for the staff to install the sponge 12. At the same time, it can protect the connecting piece 8 when the lifting plate 20 contacts the connecting piece 8.

[0036] In this embodiment: when the lifting plate 20 moves upward and squeezes the connector 8, one end of the sponge 12 installed on the connector 8 retracts into the placement groove 11, and the other end contacts the lead screw 2, so that the lubricating oil can evenly lubricate the lead screw 2. The elasticity of the elastic element 7 can prevent the lubricating oil from leaking out accidentally. By pulling the rubber cylinder 15, the limiting block 13 can be slid, so as to realize the quick replacement of the sponge 12.

[0037] Specifically, when lubrication of the lead screw 2 is required, the lead screw 2 drives the lifting plate 20 to move upward, thereby causing the lifting plate 20 to press the connecting piece 8, causing the connecting piece 8 to retract into the placement groove 11. This allows one end of the sponge 12 to be inside the placement groove 11, while the other end contacts the lead screw 2, ensuring that all four sets of sponges 12 are in contact with the lead screw 2. This provides uniform lubrication to the lead screw 2 and prevents uneven application of lubricant by the operator. When the lifting plate 20 moves downward, the elastic force of the elastic element 7 drives the connecting piece 8 downward, preventing lubricant leakage. By pulling the rubber cylinder 15, the limiting block 13 can slide, allowing the fixing plate 19 to be placed inside the connecting groove 17. The cooperation between the second T-shaped block 14 and the second T-shaped groove 16 limits the movement direction of the limiting block 13. The elastic force of the spring 18 keeps the limiting block 13 in place of the sponge 12, enabling quick replacement of the sponge 12.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
