Description

Technical Field

[0001] The invention relates to the technical field of concrete discharging devices, and in particular to a concrete anti-wall hanging silo. Background Art

[0002] Concrete is an engineering material made by mixing cement as a binder, sand and stone as aggregates, and water in a certain proportion. During the production and use of concrete, a silo is needed as a device for storing and supplying concrete. However, during the discharge process of existing concrete, due to its unique fluidity and cohesiveness, the inner wall of the silo is prone to adhere to the concrete during discharge. If it is not cleaned, the actual capacity of the silo will be reduced. At the same time, the solidified concrete on the wall will cause wear on the inner wall of the silo, shortening the service life of the silo. It is also easy to fall off during discharge, causing discharge blockage, affecting the normal supply of materials, and even posing a safety hazard.

[0003] In the existing production process, for the concrete hanging on the wall of the silo, the inner wall of the silo is usually cleaned regularly after the production is completed. Common methods generally include using mechanical methods such as knocking, vibration, and crushing to make the solidified concrete blocks fall off; or using media such as water flow and high-pressure gas to act on the concrete to crush it; or decomposing the concrete by immersing it in chemical reagents for cleaning. However, no matter which of the above methods is used, it requires a lot of manpower and material resources, which is not conducive to the stable mass production of concrete.

[0004] The Chinese utility model patent with authorization announcement number CN221892249U proposes a concrete silo, which includes: a silo body, a support platform, a feed port, a discharge pipe, a rotating pipe and stirring blades. The bottom of the silo body is penetrated by a support platform, the left side of the upper surface of the silo body is penetrated by a feed port, the bottom of the silo body is penetrated by a discharge pipe, the center of the upper surface of the silo body is rotatably provided with a rotating pipe through a bearing, the outer top of the rotating pipe is fixedly provided with a driven pulley, the left and right side surfaces of the rotating pipe are fixedly provided with a plurality of stirring blades, and the bottom of the rotating pipe is fixedly provided with a discharge assembly; the utility model discharges materials in the form of a material blocking plug inserted into the discharge pipe. During the process of the material blocking plug being inserted into the discharge pipe, the material blocking plug will scrape off the concrete attached to the inner wall surface of the discharge pipe to prevent the discharge pipe from being blocked, thereby ensuring the normal use of the concrete silo.

[0005] In the above structure, although the concrete on the inner wall of the silo body can be scraped off by the scraper plate, since the scraper plate and the stirring blade are connected vertically and horizontally to form multiple angle structures, it is easy for the concrete to accumulate and adhere to the stirring blade and the scraper plate when scraping. Due to the characteristics of concrete, it is difficult to clean the stirring blade and the scraper plate only by adding water and stirring the adhered concrete. It is also necessary to clean the stirring blade and the scraper plate regularly, which increases maintenance costs and reduces production efficiency. Summary of the invention

[0006] In view of the deficiencies existing in the prior art, the present invention provides a concrete anti-wall silo, which solves the problem in the prior art that concrete adhered to the scraper plate and the mixing blade is difficult to clean and needs to be cleaned regularly, which increases maintenance costs and reduces production efficiency.

[0007] According to an embodiment of the present invention, a concrete anti-wall silo comprises:

[0008] A silo, wherein the silo is fixedly arranged horizontally, wherein a columnar accommodating cavity is arranged in a hollow space inside the silo, and wherein a feed inlet and a discharge outlet are connected to and arranged at the top and bottom of the silo respectively;

[0009] The first cleaning mechanism includes a rotating ring and a first driving source, the rotating ring is rotatably arranged on the top of the accommodating chamber, the first driving source is fixedly arranged on the top of the warehouse body, the first driving source drives the rotating ring to rotate forward or reversely, and a pair of spiral scrapers are fixedly connected to the bottom of the rotating ring, the spiral scrapers extend into the accommodating chamber and are separated from the inner side wall of the accommodating chamber.

[0011] The technical principle of the present invention is as follows: when in use, concrete is put into the feed port, the first driving source is started, the driving rotating ring drives the spiral scraper to rotate forward, and when the spiral scraper rotates to form an acute angle with the rotating rod, the rotating rod will rotate with the rotation of the spiral scraper because the rotating rod and the limit shaft are in rotational cooperation. Since the surface of the spiral scraper is inclined, it will also provide a downward component force to the rotating rod when it rotates, thereby driving the rotating rod to move downward along the surface of the spiral scraper; when the rotating rod rotates to the bottom of the accommodating cavity, the driving rotating ring Reversing, the back end of the spiral scraper will rotate to form an obtuse angle with the rotating rod, and at the same time provide an upward component force to the rotating rod, thereby driving the rotating rod to move upward along the surface of the spiral scraper. The spiral scraper and the rotating rod are linked to stir the concrete in the silo; after the concrete is discharged through the discharge port, the above operation is repeated. When the spiral scraper rotates, the concrete adhered to the inner wall of the silo can be scraped off, and the rotating rod is against the spiral scraper and moves up and down along the surface of the spiral scraper, which can effectively clean the front and back surfaces of the spiral scraper.

[0012] Furthermore, the first driving source includes a bidirectional motor, the output end of the bidirectional motor is fixedly connected to a driving gear, and a plurality of meshing teeth are evenly arranged around the inner wall of the rotating ring, and the meshing teeth can mesh with the driving gear to drive the rotating ring to rotate.

[0013] Furthermore, a driven gear is fixedly connected to the top of the limiting shaft, and the driven gear is meshed with the driving gear. A fixing frame is fixedly connected to the bottom of the inner wall of the warehouse body. A fixing frame is also sleeved on the bottom of the limiting shaft, and the fixing frame is fixedly connected to the inner wall of the warehouse body.

[0014] Furthermore, a damping shaft is fixedly disposed in the rotating seat, and the damping shaft is sleeved with the limiting shaft.

[0015] Furthermore, grooves are provided at both ends of the rotating seat, the rotating rod is slidably arranged in the grooves, and the bottom of the rotating rod and the bottom of the groove are fixedly connected by a spring.

[0016] Furthermore, one end of the rotating rod away from the rotating seat is set as a cylinder, and the cylindrical surface of the cylinder is tangent to the spiral scraper when the spiral scraper rotates to abut against the rotating rod.

[0017] Furthermore, a second driving source is fixedly arranged on the top of the warehouse body, and the second driving source includes a hydraulic cylinder, and an output end of the hydraulic cylinder is fixedly connected to a telescopic rod, and the bottom of the telescopic rod is fixedly connected to the top end of the limiting shaft.

[0018] Furthermore, a third cleaning structure is also provided at the bottom of the silo body, and the third cleaning structure includes a discharge portion and a discharge chamber, the discharge portion is fixedly connected to the bottom of the silo body, the discharge chamber is arranged in the discharge portion, and the discharge chamber is arranged in a vortex shape, the upper and lower ends of the discharge chamber are respectively connected to the accommodating chamber and the discharge port, and a discharge fan blade is also arranged in the discharge chamber for horizontal rotation, a motor is fixedly arranged outside the discharge portion, and the output end of the motor is fixedly connected to the discharge fan blade for driving the discharge fan blade to rotate.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The spiral scraper is driven to rotate by the first driving source. When there is concrete in the silo, the spiral scraper can stir the concrete on the periphery; when the concrete in the silo is emptied, the spiral scraper can scrape the concrete adhering to the inner wall of the silo. Compared with the traditional scraper, when the inclined spiral scraper scrapes the concrete, there is no supporting structure under the scraped concrete, and the spiral scraper and the inner wall of the accommodating cavity can provide less supporting force to it, so it is easier to be cleaned and dropped, and the cleaning effect is better.

[0023] 2. The rotation of the spiral scraper drives the rotating rod to rotate. Since the surface of the spiral scraper is inclined, it will provide an axial component of force to the rotating rod when it rotates, thereby driving the rotating rod to move downward or downward along the surface of the spiral scraper. When there is concrete in the silo, the rotating rod can stir the concrete in the middle; when the concrete in the silo is emptied, by controlling the rotation direction of the spiral scraper, the rotating rod is driven to contact the spiral scraper and move up and down along the surface of the spiral scraper, and the front and back surfaces of the spiral scraper are scraped, which is more conducive to subsequent cleaning and reduces maintenance costs.

[0024] 3. When the rotating rod is driven by the spiral scraper to move up and down, the concrete adhering to the limit shaft will also be cleaned by the rotating seat. Compared with the traditional mixing blade, the rotating rod has a smaller contact area with the concrete, less concrete adheres to it, is easier to clean, and has lower maintenance costs.

[0025] Therefore, the present invention links the rotating rod with the spiral scraper, which can scrape and clean the inner wall of the silo, the spiral scraper and the limiting shaft while taking into account the stirring ability. It is highly practical and the self-cleaning ability of the silo is greatly enhanced. The cleaning cycle can be extended according to actual production needs, reducing maintenance costs and improving production efficiency. At the same time, the scraped concrete can effectively increase the utilization rate of concrete in the silo and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0037] Embodiment 1:

[0038] like Figure 1-3 As shown, an embodiment of the present invention proposes a concrete anti-wall hanging silo, which includes a silo body 1, the upper part of the silo body 1 is preferably set to a columnar shape, and the lower part is preferably set to a cone shape. A plurality of supporting legs 14 are fixedly arranged around the lower part of the silo body 1 to fix the silo body 1 horizontally. Inside the silo body 1, a columnar accommodating chamber 12 is hollowly arranged, and the accommodating chamber 12 is connected to a feed port 11 at the top of the silo body 1. The feed port 11 is set to a funnel-shaped structure that is wide at the top and narrow at the bottom, so as to facilitate the transfer of the concrete into the silo body 1, and the accommodating chamber 12 is connected to a discharge port 16 at the bottom of the silo body 1.

[0039] like Figure 1-4 As shown, in this embodiment, the silo also includes a first cleaning mechanism, which includes a rotating ring 2 and a first driving source. The rotating ring 2 is rotatably arranged on the top of the accommodating chamber 12, and the first driving source is fixedly arranged on the top of the silo body 1. The first driving source includes but is not limited to a bidirectional motor 22, a stepping motor or a servo motor to drive the rotating ring 2 to rotate forward or reverse. In this embodiment, the first driving source is set to a bidirectional motor 22, and the output end of the bidirectional motor 22 is fixedly connected to a driving gear 24. A plurality of meshing teeth 21 are evenly arranged around the inner wall of the rotating ring 2, and the meshing teeth 21 can mesh with the driving gear 24. A pair of spiral scrapers 23 are fixedly connected to the bottom of the rotating ring 2, and the plate width and plate thickness of the spiral scraper 23 are the same, and the spiral angle of the spiral scraper 23 is uniform and consistent up and down. The spiral scraper 23 extends into the accommodating chamber 12 and is separated from the inner side wall of the accommodating chamber 12. When the spiral scraper 23 rotates with the rotating ring 2, the inner wall of the accommodating chamber 12 can be scraped.

[0040] like Figure 2-5 As shown, in the present embodiment, the silo also includes a second cleaning mechanism, which includes a limiting shaft 3, which is coaxially fixed in the accommodating chamber 12, and a fixing frame 32 is fixedly connected to the bottom of the accommodating chamber 12, and the fixing frame 32 is composed of a plurality of support rods 321 and a fixing ring 322, one end of the plurality of support rods 321 is fixedly connected to the inner wall of the accommodating chamber 12, and the other end surrounds the fixing ring 322 and is fixedly connected thereto, and the fixing ring 322 is sleeved on the bottom of the limiting shaft 3, and a pair of limiting rings 33 are fixedly connected to the upper and lower end surfaces of the limiting ring 33, so that the limiting shaft 3 can stably rotate in the accommodating chamber 12, and a rotating seat 4 is also rotatably sleeved on the limiting shaft 3, and a pair of rotating rods 41 are telescopically arranged at both ends of the rotating seat 4 perpendicular to the inner wall of the silo body 1, combined with Figure 7As shown, grooves 43 are provided at both ends of the rotating seat 4, and the rotating rod 41 is slidably arranged in the groove 43. The bottom of the rotating rod 41 and the bottom of the groove 43 are fixedly connected by a spring 44, so that the rotating rod 41 can abut against the inner wall of the warehouse body 1 to prevent the rotating rod 41 from falling. At the same time, the rotating rod 41 is set as a cylinder at one end away from the rotating seat 4. The cylindrical surface of the cylinder is tangent to the spiral scraper 23 when the spiral scraper 23 rotates to abut against the rotating rod 41, so that the rotating rod 41 can move closely against the plate surface of the spiral scraper 23 when abutting against the spiral scraper 23, thereby effectively scraping the concrete on the spiral scraper 23;

[0041] like Figure 4 Figure 6 and Figure 7 As shown, further, as another implementation of this embodiment, a driven gear 31 is fixedly connected to the top of the limit shaft 3, and the driven gear 31 is meshed with the driving gear 24. At this time, the limit shaft 3 can be driven by the bidirectional motor 22 to rotate in the opposite direction to the rotating ring 2. At this time, the limit shaft 3 and the rotating seat 4 can be interference fit to increase the rotational friction between the limit shaft 3 and the rotating seat 4 to ensure that the rotational friction between the two is greater than the friction between the rotating rod 41 and the inner wall of the accommodating chamber 12. Preferably, a damping shaft 42 is fixedly arranged in the rotating seat 4, and the damping shaft 42 is sleeved with the limit shaft 3. Based on the above implementation, the rotating rod 41 and the spiral scraper 23 rotate in opposite directions relative to each other, which can provide greater pressure when the rotating rod 41 and the spiral scraper 23 are against each other, thereby providing a better scraping effect.

[0042] The technical principle of the present invention is as follows: when in use, concrete is put into the feed port 11, the bidirectional motor 22 is started, the rotating ring 2 is driven to drive the spiral scraper 23 to rotate forward, the limiting shaft 3 is driven to drive the rotating rod 41 to rotate reversely, and when the spiral scraper 23 rotates to form an acute angle with the rotating rod 41, because the rotating rod 41 and the limiting shaft 3 are in rotational cooperation, the rotating rod 41 will rotate with the push of the spiral scraper 23, and because the plate surface of the spiral scraper 23 is inclined, it will also provide a downward component of force to the rotating rod 41 when it rotates, thereby driving the rotating rod 41 to move downward along the plate surface of the spiral scraper 23; when the rotating rod 41 rotates to the bottom of the accommodating chamber 12 When the rotary ring 2 is driven to reverse, the back end of the spiral scraper 23 will rotate to form an obtuse angle with the rotating rod 41, and at the same time provide an upward component of force to the rotating rod 41, thereby driving the rotating rod 41 to move upward along the surface of the spiral scraper 23. The spiral scraper 23 and the rotating rod 41 can be linked to stir the concrete in the silo 1; after the concrete is discharged through the discharge port 16, the above operation is repeated. When the spiral scraper 23 rotates, the concrete adhered to the inner wall of the silo 1 can be scraped off, and the rotating rod 41 is against the spiral scraper 23 and moves up and down along the surface of the spiral scraper 23, which can effectively clean the front and back surfaces of the spiral scraper 23.

[0043] In this embodiment, the spiral scraper 23 and the rotating rod 41 are driven to rotate by the bidirectional motor 22. When there is concrete in the silo, the spiral scraper 23 and the rotating rod 41 can stir the concrete located at the periphery and the center respectively; when the concrete in the silo is emptied, the spiral scraper 23 can scrape off the concrete adhered to the inner wall of the silo, and the scraper rod can scrape off the concrete adhered to the spiral scraper 23. Compared with the traditional scraper, when the inclined spiral scraper 23 scrapes the concrete, there is no supporting structure under the scraped concrete, and the spiral scraper 23 and the inner wall of the accommodating chamber 12 can provide less supporting force to it, so it is easier to be cleaned and dropped, and the cleaning effect is better; the rotating rod 41 is driven to rotate by the rotation of the spiral scraper 23. Because the plate surface of the spiral scraper 23 is inclined, it will provide an axial component of force to the rotating rod 41 when it rotates, thereby driving the rotating rod 41 to move downward or along the plate surface of the spiral scraper 23 When the rotary rod 41 moves downward and there is concrete in the silo, the rotary rod 41 can stir the concrete in the middle; when the concrete in the silo is emptied, by controlling the rotation direction of the spiral scraper 23, the rotary rod 41 can be driven to contact the spiral scraper 23 and move up and down along the surface of the spiral scraper 23, so as to scrape the front and back surfaces of the spiral scraper 23, which is more conducive to subsequent cleaning and reduces maintenance costs; in the process of the rotary rod 41 being driven by the spiral scraper 23 to move up and down, the concrete adhered to the limit shaft 3 will also be cleaned by the rotating seat 4. When the rotary rod 41 rotates to the bottom of the limit shaft 3, the upper part of the fixed frame 32 can also be cleaned. Compared with traditional stirring blades, the rotary rod 41 has a smaller contact area with the concrete, less concrete adhered to it, is easier to clean, and has lower maintenance costs. A detachable maintenance port can also be provided on the top of the silo body 1 to regularly clean the rotary rod 41, thereby reducing maintenance costs to a greater extent.

[0044] The present invention links the rotating rod 41 with the spiral scraper 23, and can scrape and clean the inner wall of the silo, the spiral scraper 23 and the limiting shaft 3 while taking into account the stirring ability. It is highly practical and the self-cleaning ability of the silo is greatly improved. The cleaning cycle can be extended according to actual production needs, which reduces maintenance costs and improves production efficiency. At the same time, the scraped concrete can effectively increase the utilization rate of the concrete in the silo and reduce production costs.

[0045] Example 2

[0046] like Figure 8 and Fig. 9 As shown, according to another implementation of an embodiment of the present invention, a second driving source is also fixedly arranged on the top of the silo body 1 of the concrete anti-wall silo, and the second driving source includes but is not limited to a hydraulic cylinder 6, a pneumatic cylinder or an electric cylinder that can drive the limit shaft 3 to telescopically move. In this embodiment, the second driving source is set to a hydraulic cylinder 6, and the output end of the hydraulic cylinder 6 is fixedly connected to a telescopic rod 61, and the bottom of the telescopic rod 61 is fixedly connected to the top of the limit shaft 3.

[0047] Based on the above further improvement, since the hydraulic cylinder 6 is used to drive the rotating rod 41 to move up and down, the axial displacement of the rotating rod 41 no longer depends on the axial component force provided by the spiral scraper 23 after it abuts against it, thereby avoiding the situation where the rotating rod 41 may be stuck by hard materials in the concrete when abutting against the spiral scraper 23, and cannot be normally displaced along the axial direction of the spiral scraper 23 for cleaning, which is more conducive to stable production of the device.

[0048] Example 3

[0049] like Figure 1-3 As shown, according to another implementation of an embodiment of the present invention, the lower part of the accommodating chamber 12 of the concrete anti-wall silo is set to a reducing slope 13 that is wide at the top and narrow at the bottom, so that the concrete gathers at the middle and bottom and then discharges. The bottom of the reducing slope 13 is also provided with a third cleaning structure, and the third cleaning structure includes a discharge portion 15 and a discharge chamber 17. The discharge portion 15 is fixedly connected to the bottom of the silo body 1, and the discharge chamber 17 is arranged in the discharge portion 15, and the discharge chamber 17 is arranged in a vortex shape. The upper and lower ends of the discharge chamber 17 are respectively connected to the accommodating chamber 12 and the discharge port 16, and a discharge fan blade 5 is arranged in the discharge chamber 17 for horizontal rotation. A motor is fixedly arranged outside the part 15, and the output end of the motor is fixedly connected to the rotating shaft of the discharging fan blade 5 to drive the discharging fan blade 5 to rotate. The bottom of the discharging chamber 17 is connected to the discharging port 16. Furthermore, the discharging fan blade 5 includes a plurality of impellers 51, and the impellers 51 are rounded rectangles, and the outer edges of the impellers 51 are separated from the inner wall of the discharging chamber 17. Furthermore, the discharging part 15 also includes a fixed shell 151 and a connecting shell 152. The fixed shell 151 is fixedly connected to the bottom of the warehouse body 1, and the connecting shell 152 is detachably fixed to the fixed shell 151. The discharging port 16 is connected and arranged at the bottom of the connecting shell 152.

[0050] Based on the above further improvements, the speed and amount of concrete discharging can be accurately controlled by driving the discharging blades 5 to rotate through a motor. Since the outer edge of the impeller 51 is separated from the inner wall of the discharging chamber 17, the concrete can be prevented from flowing out of the accommodating chamber 12 when the discharging blades 5 are not started. A stop valve can also be externally connected to the discharge port 16, and then the discharging blades 5 can be started to rotate to stir the concrete in the lower part to prevent it from solidifying and affecting the discharging. The discharging blades 5 can scrape the inner wall of the discharging chamber 17 during rotation to prevent it from hanging on the wall, thereby ensuring stable concrete discharging. The connecting shell 152 is detachably fixed to the fixed shell 151 by bolts or other fixing methods. It is only necessary to remove the connecting shell 152 regularly and take out the discharging blades 5 for cleaning, thereby greatly reducing the maintenance cost.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
