Description

Technical Field

[0001] The utility model relates to the field of concrete production, in particular to a concrete production unloading mechanism. Background Art

[0002] Concrete is typically composed of cement, aggregates (sand, gravel), water, and admixtures. Cement is a cementitious material that binds the aggregates together. Aggregates are divided into fine aggregate (sand) and coarse aggregate (gravel). Sand fills the spaces between the gravel, while gravel provides structural support. Water is essential for concrete mixing and hydration, and its amount affects the concrete's performance and strength.

[0003] However, during the concrete production process, the sand and aggregate in the concrete raw materials are easily stuck at the discharge port of the storage bin, which will cause discharge difficulties and affect production efficiency. In response to the above defects, we propose a concrete production unloading mechanism. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a concrete production blanking mechanism.

[0005] In order to solve the problems existing in the prior art, the present invention adopts the following technical solutions: a concrete production blanking mechanism, comprising:

[0006] Concrete storage silo body,

[0011] Preferably, the front of the first scraper roller is fixedly connected to the back of the driving pulley, the front of the two second scraper rollers are fixedly connected to the back of the driving gear and the driven gear respectively, and the driving gear and the driven gear are meshed for transmission.

[0012] Preferably, the driving pulley and the driven pulley are connected via a belt transmission.

[0013] Preferably, both ends of the two second scraper rollers extend to the outside of the concrete storage silo body, and are fixedly connected to the surfaces of the first closing plate and the second closing plate respectively through connecting rods.

[0014] Preferably, the vibration assembly includes cams fixedly mounted on the back of the two second scraper rollers, a mounting plate fixedly mounted on the back of the concrete storage bin body, a through hole opened on the upper surface of the mounting plate, a guide rod slidably mounted on the inner wall of the through hole, and a striking hammer fixedly mounted on the upper end of the guide rod.

[0015] Preferably, the lower end of the guide rod passes through the through hole, extends to the bottom of the mounting plate, and is fixedly mounted with a baffle.

[0016] Preferably, a spring is sleeved on the surface of the guide rod, one end of the spring is fixedly connected to the upper surface of the baffle, and the other end of the spring is fixedly connected to the lower surface of the mounting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By setting up the discharge structure and the anti-blocking structure, when the driving assembly is working, the second scraper roller and the first scraper roller will be driven to rotate. At the same time as the two second scraper rollers rotate, the connecting rod will be driven to rotate, thereby driving the first closing plate and the second closing plate to rotate, and then the discharge end of the concrete storage silo body will be opened, so that the material is discharged from the interior of the concrete storage silo body. At the same time, when the discharge end of the concrete storage silo body is opened, the rotation of the second scraper roller and the first scraper roller can stir the material inside the concrete storage silo body to loosen it, thereby avoiding the problem of difficulty in discharging the material.

[0019] 2. By setting up a vibration component, when the two second scraper rollers rotate, the cam will be driven to rotate. After the cam rotates, the raised surface of the cam will separate from the baffle. At this time, the spring reset will drive the hammer to hit the mounting plate, thereby transmitting the vibration force to the concrete storage silo body, which can further make the material discharge smoother.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-6 The utility model provides a technical solution: a concrete production unloading mechanism, including: a concrete storage bin body 1, a discharge structure, and an anti-blocking structure.

[0030] See Figure 4 The discharge structure is arranged at the discharge end of the concrete storage bin body 1, and is used to discharge the concrete inside the concrete storage bin body 1. It includes a first closing plate 2 and a second closing plate 3. The first closing plate 2 and the second closing plate 3 can be used to seal the discharge end of the concrete storage bin body 1.

[0031] The anti-blocking structure includes a vibration component arranged at the rear of the concrete storage bin body 1, a scraper component arranged inside the concrete storage bin body 1, and a drive component arranged at the front of the concrete storage bin body 1 to drive the scraper component and the vibration component to work.

[0032] See Figure 3 and Figure 5The driving assembly includes a driving gear 6, a driven gear 7, a driving pulley 8, and a driven pulley 9 fixedly mounted on the front of the driving gear 6, and a motor 10 that can drive the driving pulley 8 to rotate is fixedly mounted on the front of the concrete storage silo body 1, and the driving pulley 8 and the driven pulley 9 are connected by a belt drive.

[0033] See Figure 1 、 3 and 4, the scraper assembly includes a first scraper roller 4 and a second scraper roller 5 which are respectively rotatably connected to the inner wall of the concrete storage silo body 1, and the number of the second scraper rollers 5 is two, the front of the first scraper roller 4 is fixedly connected to the back of the driving pulley 8, and the front of the two second scraper rollers 5 are respectively fixedly connected to the back of the driving gear 6 and the driven gear 7, and the driving gear 6 is meshed with the driven gear 7 for transmission.

[0034] The driving motor 10 can drive the driving pulley 8 to rotate. At this time, the first scraper roller 4 will rotate synchronously, and the driven pulley 9 can be driven to rotate through the transmission of the belt. When the driven pulley 9 rotates, it can drive the driving gear 6 to rotate. The driving gear 6 and the driven gear 7 are engaged and transmitted, thereby driving the two second scraper rollers 5 to rotate.

[0035] The two ends of the two second scraper rollers 5 extend to the outside of the concrete storage bin body 1 respectively, and are fixedly connected to the surfaces of the first closing plate 2 and the second closing plate 3 respectively through the connecting rod 11. When the two second scraper rollers 5 rotate, they will drive the first closing plate 2 and the second closing plate 3 to rotate synchronously, so that the rotating first closing plate 2 and the second closing plate 3 can be used to block or open the discharge end on the concrete storage bin body 1. At the same time, changing the opening angle of the first closing plate 2 and the second closing plate 3 can control the amount of discharge. When the second scraper roller 5 and the first scraper roller 4 rotate, the material inside the concrete storage bin body 1 can be stirred to loosen it, thereby avoiding the problem of difficulty in discharging the material.

[0036] See Figure 6 The vibration assembly includes cams 12 fixedly mounted on the back of the two second scraper rollers 5, a mounting plate 13 fixedly mounted on the back of the concrete storage silo body 1, a through hole opened on the upper surface of the mounting plate 13, a guide rod 14 slidably mounted on the inner wall of the through hole, and a knock hammer 15 fixedly mounted on the upper end of the guide rod 14. The lower end of the guide rod 14 passes through the through hole and extends to the bottom of the mounting plate 13, and is fixedly mounted with a baffle 16. When the raised end of the cam 12 contacts the baffle 16, the baffle 16 can be driven to move upward, and the knock hammer 15 can be driven to move upward.

[0037] A spring 17 is sleeved on the surface of the guide rod 14, one end of the spring 17 is fixedly connected to the upper surface of the baffle 16, and the other end of the spring 17 is fixedly connected to the lower surface of the mounting plate 13. When the first closing plate 2 and the second closing plate 3 block the discharge end of the concrete storage silo body 1, the spring 17 is in a contracted state.

[0038] When the two second scraper rollers 5 rotate, the cam 12 is driven to rotate. After the cam 12 rotates, the raised surface of the cam 12 will separate from the baffle 16. At this time, the spring 17 resets and drives the hammer 15 to knock on the mounting plate 13, thereby transmitting the vibration force to the concrete storage silo body 1, and further making the material discharge smoother.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
