Description

Technical Field

[0001] This application relates to the field of concrete production technology, specifically to a concrete production silo. Background Technology

[0002] In the concrete production process, the silo is a key piece of equipment for storing raw materials, and its performance directly affects production efficiency and product quality. When concrete raw materials such as cement are stored in the silo, they are prone to pile up at the bottom of the silo due to gravity, which makes it difficult for the material to be discharged smoothly. This not only requires frequent manual knocking or poking operations, increasing labor intensity, but also leads to production interruption and affects continuous operation.

[0003] However, traditional silos rely on gravity-fed material flow. When raw materials are stored for a long time, they tend to accumulate and clump at the bottom of the silo, causing interruptions in material flow. This requires frequent manual tapping of the silo walls or the use of material-pouring tools to assist in unloading, which not only increases labor intensity but may also lead to safety accidents due to improper operation. Furthermore, manual intervention results in poor production continuity, making it difficult to meet the needs of continuous industrial production.

[0004] Therefore, it is necessary to provide a concrete production silo to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a concrete production silo that solves the problem of material feeding difficulties caused by material accumulation and clumping in traditional silos.

[0007] The technical solution adopted by this application to solve its technical problem is: a concrete production silo, including a support frame and a silo body, the silo body being installed on the support frame, and also including a striking assembly, the striking assembly including a mounting frame fixed on the support frame, two oppositely arranged positioning plates fixed on both sides of the upper end of the mounting frame, two oppositely arranged connecting seats fixed on each positioning plate, a sleeve fixed between the two connecting seats, a striking rod slidably installed inside the sleeve, the two sides of the striking rod passing through the connecting seats and slidably connected to the connecting seats, a circular plate fixedly installed on the outer wall of one end of the striking rod, the circular plate sliding inside the sleeve, a spring provided inside the sleeve, the spring being sleeved on the striking rod for pushing the striking rod to reset;

[0008] The two positioning plates are provided with connecting components for moving the striking rod. The connecting components include drive shafts that are rotatably mounted on the other side of the positioning plates. The lower end of the drive shafts is rotatably connected to the mounting frame. The mounting frame is provided with a drive component for rotating the two drive shafts.

[0009] Furthermore, a drive shaft is rotatably mounted on the drive shaft, a connecting shaft is rotatably connected to one side of the drive shaft, and one side of the connecting shaft is rotatably connected to the striking rod. A mounting plate is fixed on the drive shaft, and paddles are fixed on both sides of the mounting plate. A stop block is fixed on the drive shaft. When the mounting plate drives the paddles to rotate, the paddles move the stop block, causing the drive shaft to rotate. The rotation of the drive shaft causes the connecting shaft to move, which in turn causes the striking rod to move to the other side. When the paddles rotate 90 degrees, the stop block disengages from the paddles, and the spring force pushes the striking rod to move and strike the lower outer wall of the hopper body.

[0010] Furthermore, the drive assembly includes a second drive motor fixedly mounted on a mounting bracket. One end of the output shaft of the second drive motor and the lower end of one of the transmission shafts are both fixed with a first synchronous pulley. A first synchronous belt is driven and sleeved on the two first synchronous pulleys. The other end of the output shaft of the second drive motor and the lower end of the other transmission shaft are both fixed with a second synchronous pulley. A second synchronous belt is driven and sleeved on the two second synchronous pulleys.

[0011] Furthermore, a discharge pipe is fixed to the lower end of the hopper body, and a discharge port is provided on one side of the discharge pipe.

[0012] Furthermore, a spiral blade is rotatably installed inside the unloading pipe, and a first drive motor is fixed on the other side of the unloading pipe. The output end of the first drive motor passes through the unloading pipe and is fixedly connected to the spiral blade.

[0013] Furthermore, a striking head is fixed on the striking rod, and protective plates are provided on both sides of the hopper body, with the striking head in contact with the protective plates.

[0014] Furthermore, an end cap is provided at the upper end of the hopper body, and a feed inlet is provided at the upper end of the end cap.

[0015] The beneficial effects of this application are as follows: The concrete production silo provided by this application realizes the periodic automatic knocking of the lower outer wall of the silo body by setting a knocking component, which effectively prevents concrete raw materials from accumulating and clumping at the bottom of the silo due to gravity. It avoids the cumbersome and safety hazards of relying on manual knocking or churning operations in traditional silos, ensures that raw materials can be discharged smoothly, reduces production interruptions caused by material accumulation, and thus improves the continuity and efficiency of concrete production.

[0026] 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.

[0027] 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.

[0028] like Figure 1-6 As shown, this application provides a concrete production silo, including a support frame 1, a silo body 2, and a striking component. The silo body 2 is fixedly installed on the upper part of the support frame 1 by bolts. The upper end of the silo body 2 is provided with an end cap 3 with a feed inlet, and the lower end is connected to a discharge pipe 4. The striking component is fixed in the middle of the support frame 1 and is used to periodically strike the lower outer wall of the silo body 2 to prevent material from caking and accumulating.

[0029] The end cap 3 is sealed to the upper end of the silo body 2 via a flange. The inlet is used to connect to the concrete raw material conveying pipeline. The discharge pipe 4 is welded to the bottom outlet of the silo body 2, and a discharge port is opened on one side. The spiral blade 6 is rotatably installed inside. The first drive motor 5 is fixed to the outside of the discharge pipe 4 via a motor base. The output shaft passes through the side wall of the discharge pipe 4 and is keyed to the spiral blade 6. When the first drive motor 5 starts, the spiral blade 6 rotates and pushes the material to be discharged evenly from the discharge port, realizing quantitative discharge.

[0030] The mounting frame 7 is welded to the middle two sides of the support frame 1 by angle steel to support the striking component. A positioning plate 8 is fixed on each of the upper two sides of the mounting frame 7. Two connecting seats 9 are symmetrically arranged on each positioning plate 8. The two connecting seats 9 are fixed to the sleeve 10 by bolts. The axis of the sleeve 10 is parallel to the side wall of the hopper body 2.

[0031] The striking rod 11 passes through the through hole of the sleeve 10 and the connecting seat 9 and can slide along the axial direction of the sleeve. The striking rod 11 inside the sleeve 10 is fixed with a circular plate, which is slidably connected to the sleeve 10. The other end is fixed with a striking head 13, which is made of wear-resistant steel and has an arc surface.

[0032] Spring 12 is sleeved on striking rod 11, with its two ends abutting against the circular plate and the inner wall of sleeve 10 respectively, to provide restoring elasticity after striking.

[0033] Two drive shafts 14 are respectively vertically rotatably mounted on the other side of two positioning plates 8, and their lower ends are rotatably connected to the mounting bracket 7 through bearings. The drive shaft 15 is mounted on the drive shaft 14 through a deep groove ball bearing, and one end of it is rotatably connected to the shaft 16. A stop block 24 is welded to the middle of the upper surface of the drive shaft 15.

[0034] A mounting plate 17 is fixed on the upper part of the drive shaft 14, and two levers 18 are symmetrically arranged on the edge of the mounting plate 17.

[0035] When the drive shaft 14 rotates, the mounting plate 17 drives the toggle block 18 to rotate. The toggle block 18 periodically moves the stop block 24, causing the drive shaft 15 to swing around the axis of the drive shaft 14. This swings the striking rod 11 away from the hopper body 2 via the connecting shaft 16, compressing the spring 12. When the toggle block 18 rotates 90° and disengages from the stop block 24, the spring 12 releases its elasticity, pushing the striking rod 11 to quickly strike the side wall of the hopper body 2, thus completing one striking action.

[0036] The second drive motor 19 is fixed to the middle of the mounting bracket 7 by a motor base. The first synchronous pulley 20 and the second synchronous pulley 22 are respectively installed at both ends of the output shaft. The lower end of the left drive shaft 14 is connected to the first synchronous pulley 20 by a key, and the two are driven by the first synchronous belt 21. The lower end of the right drive shaft 14 is connected to the second synchronous pulley 22 by a key, and the two are driven by the second synchronous belt 23. The second drive motor 19 drives the two drive shafts 14 to rotate synchronously through the synchronous belt, ensuring that the two striking rods 11 can strike the hopper body 2.

[0037] Working principle: Concrete raw materials, such as cement, enter the silo body 2 through the feed inlet at the upper end of the end cover 3. The end cover 3 and the silo body 2 are sealed together by a flange to prevent dust leakage. Under the action of gravity, the raw materials accumulate at the bottom of the silo body 2. The first drive motor 5 is started, and the output shaft of the first drive motor 5 is connected by a key to drive the spiral blades 6 to rotate inside the discharge pipe 4. The spiral structure of the spiral blades 6 pushes the raw materials from the bottom of the silo body 2 to the discharge port.

[0038] The striking component periodically strikes the hopper body 2 through mechanical transmission to prevent raw materials from accumulating and agglomerating at the bottom of the hopper. After the second drive motor 19 is powered on, the output shaft drives the first synchronous pulley 20 and the second synchronous pulley 22 at both ends to rotate synchronously. The first synchronous pulley 20 on the left drives the left drive shaft 14 to rotate through the first synchronous belt 21, and the second synchronous pulley 22 on the right drives the right drive shaft 14 to rotate through the second synchronous belt 23.

[0039] When the drive shaft 14 rotates, the mounting plate 17 fixed to its upper part drives the lever 18 to perform a circular motion. When the lever 18 rotates to contact the stop 24 on the drive shaft 15, the lever 18 pushes the stop 24, causing the drive shaft 15 to rotate around the axis of the drive shaft 14. The drive shaft 15 pulls the striking rod 11 away from the hopper body 2 through the connecting shaft 16, compressing the spring 12 inside the sleeve 10. At this time, the striking rod 11 is in an energy storage state.

[0040] When the lever 18 rotates 90°, it disengages from the stop block 24. The restoring force generated by the elastic deformation of the spring 12 is released instantly, pushing the striking rod 11 to move rapidly along the axial direction of the sleeve 10, causing the striking head 13 to strike the lower outer wall of the hopper body 2. The striking head 13 is made of wear-resistant steel and has an arc surface, which can enhance the striking impact and reduce wear.

[0041] The drive shaft 14 rotates continuously, and the above process is repeated once for every rotation of the paddle block 18, so as to realize the periodic alternating knocking on both sides of the hopper body 2, which breaks the agglomerated structure of the raw materials and promotes the smooth sliding of the materials.

[0042] The protective plates on both sides of the hopper body 2 contact the striking head 13, which can limit the movement range of the striking rod 11, avoid excessive striking and damage to the hopper wall, and guide the striking force to be applied evenly to the key parts of the hopper body.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
