Description

Technical Field

[0001] The utility model belongs to the field of mortar raw material bins, and particularly relates to a raw material bin with an anti-residue structure. Background Technique

[0002] The mortar raw material bin, as a key facility for storing and supplying the raw materials required for mortar production, ensures the continuity and stability of the production line and is a key link in the mortar production process. Such warehouses are usually used to store raw materials such as cement, sand, and additives.

[0003] During the use of the mortar raw material bin, the residue of raw materials is a common problem. The raw materials are prone to wall hanging and material accumulation during the flow and discharging processes in the bin, which exacerbates the residue problem. The residue will not only cause waste of raw materials and increase production costs, but also may affect the quality stability and consistency of subsequent batches of mortar. In addition, the residue may also corrode the bin body and shorten the service life of the equipment. For the residue problem of the mortar raw material bin, the traditional solutions mainly include manual cleaning and mechanical cleaning. Although manual cleaning can target some corners and complex parts and does not require the investment in large equipment, the manual cleaning speed is slow, affecting the efficiency, and the long-term physical labor is prone to fatigue. Mechanical cleaning may be inconvenient for maintenance due to the complexity of the equipment. Therefore, a new structure is needed to solve the above-mentioned problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a raw material bin with an anti-residue structure to solve the problems mentioned in the above background technique.

[0005] The utility model is realized through the following technical solutions: A raw material bin with an anti-residue structure, comprising: a storage barrel, a top plate, and a scraping disc. The inner side of the bottom of the top plate is connected with a hydraulic push rod, and the outer side of the bottom of the top plate is connected with a hydraulic rod. The bottom of the storage barrel is provided with a feeding hopper, and the bottom of the feeding hopper is provided with a feeding pipe. The scraping disc is assembled on the upper side inside the storage barrel. Above the central position of the scraping disc, there is a support plate. The bottom of the support plate is connected with the surface of the scraping disc through a plurality of support rods. The top of the support plate is connected with the hydraulic push rod through a hinge two, and the top of the hydraulic push rod is connected with the bottom of the top plate through a hinge one. An electric motor is inversely installed at the central position of the upper surface of the scraping disc, and a rotating rod is connected below the electric motor. Scraping plates and scraping strips are installed on both sides of the rotating rod.

[0006] The feeding hopper is an inverted frustum structure, and the feeding hopper and the storage barrel are integrally formed. The storage barrel, the feeding hopper, and the feeding pipe all form hollow structures. By setting the feeding hopper as an inverted frustum structure, when discharging the mortar raw materials, the mortar raw materials in the storage barrel can converge into the feeding pipe and then be discharged.

[0007] On the upper side of the outer surface of the storage bucket, a feed pipe for adding raw materials is installed. On the outer side of the lower surface of the blanking hopper, three support frames for supporting the storage bucket are evenly installed.

[0008] The blanking pipe is installed at the central position of the bottom of the blanking hopper. A valve for opening or closing the blanking pipe is installed at the lower side inside the blanking pipe. The distance from the upper surface of the valve to the top of the blanking pipe is the same as the height of the scraping bar.

[0009] The two groups of scraping plates are symmetrically installed on the left and right sides of the rotating rod. Multiple cross bars are connected between the two groups of scraping plates and the rotating rod. The two groups of scraping plates form an inverted triangular structure through the cross bars. Two scraping bars are symmetrically installed at the bottom of the two groups of scraping plates. The inclination angle of the scraping plates is the same as the inclination angle of the inner wall of the blanking hopper. Because the inclination angles of the scraping plates and the blanking hopper are the same, the scraping plates can be attached to the inner wall of the blanking hopper during the downward movement of the scraping disc, realizing the cleaning of the inside of the blanking hopper.

[0010] On the top of the support plate, two inclined hydraulic push rods are symmetrically installed through two hinge parts two. On the top of the two hydraulic push rods, hinge parts one are installed. The two hinge parts two are symmetrically installed on both sides of the bottom of the top plate. By installing the support plate, the motor can be installed below the support plate. The hydraulic push rods can push and pull the support plate to move, realizing the adjustment of the height of the scraping disc.

[0011] The top plate and the scraping disc both penetrate the upper surface to form a plurality of pressure relief holes. The top of the top plate is fixed to the top of the storage bucket by screws. The opening of the pressure relief holes can prevent the formation of negative pressure between the top plate, the scraping disc and the bottom of the storage bucket from affecting the use of the hydraulic push rods.

[0012] A collar is installed on the upper side of the outer surface of the blanking pipe. Two hydraulic rods are symmetrically installed on the top of the collar. The tops of the two hydraulic rods are respectively connected to both sides of the bottom of the top plate.

[0013] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By installing hydraulic push rods, motors, scraping discs and rotating rods inside the storage bucket, when the hydraulic push rods are opened, the scraping discs can be pushed to move downward. During the movement of the scraping discs, the residual raw materials on the inner wall of the storage bucket are pushed downward, realizing the cleaning of the inner wall of the storage bucket. At the same time, the rotating rods can be pushed into the blanking hopper and the blanking pipe. The scraping plates on the surface of the rotating rods can scrape and disperse the mortar raw materials inside the blanking hopper and the blanking pipe and then drop them downward. At the same time, through the hydraulic rods, the top plate can drive the hydraulic push rods, motors, scraping discs and rotating rods to be gradually exposed, facilitating the maintenance and repair of the hydraulic push rods, motors, etc. Description of the Drawings

[0024] Please refer to Figures 1 to 3, the utility model provides a technical solution: a raw material bin with an anti-residue structure, including: a storage barrel 100, a top plate 200, and a scraping disc 300. Inside the bottom of the top plate 200, a hydraulic push rod 220 is connected. Outside the bottom of the top plate 200, a hydraulic rod 510 is connected. At the bottom of the storage barrel 100, a blanking hopper 110 is installed. At the bottom of the blanking hopper 110, a blanking pipe 120 is installed. Inside the upper side of the storage barrel 100, a scraping disc 300 is assembled. Above the center position of the scraping disc 300, there is a support plate 320. The bottom of the support plate 320 is connected to the surface of the scraping disc 300 through a plurality of support rods 310. The top of the support plate 320 is connected to the hydraulic push rod 220 through a hinge two 230. The top of the hydraulic push rod 220 is connected to the bottom of the top plate 200 through a hinge one 210. At the center position of the upper surface of the scraping disc 300, a motor 400 is installed upside down. Below the motor 400, a rotating rod 410 is connected. On both sides of the rotating rod 410, a scraping plate 420 and a scraping strip 430 are installed.

[0025] Please refer to Figures 1 to 3 , the blanking hopper 110 is an inverted frustum structure. The blanking hopper 110 and the storage barrel 100 are integrally formed. Inside the storage barrel 100, the blanking hopper 110, and the blanking pipe 120, a hollow structure is formed. By setting the blanking hopper 110 as an inverted frustum structure, when discharging the mortar raw materials, the mortar raw materials in the storage barrel 100 can converge into the blanking pipe 120 and then be discharged.

[0026] On the upper side of the outer surface of the storage barrel 100, a feeding pipe 130 for adding raw materials is installed. On the outer side of the lower surface of the blanking hopper 110, three groups of support frames 140 for supporting the storage barrel 100 are evenly installed.

[0027] The blanking pipe 120 is installed at the center position of the bottom of the blanking hopper 110. Inside the lower side of the blanking pipe 120, a valve for opening or closing the blanking pipe 120 is installed. The distance from the upper surface of the valve to the top of the blanking pipe 120 is the same as the height of the scraping strip 430.

[0028] The scraping plates 420 are symmetrically installed in two groups on the left and right sides of the rotating rod 410. Between the two groups of scraping plates 420 and the rotating rod 410, a plurality of cross bars 440 are connected. The two groups of scraping plates 420 form an inverted triangular structure through the cross bars 440. At the bottom of the two groups of scraping plates 420, two groups of scraping strips 430 are symmetrically installed. The inclination angle of the scraping plates 420 is the same as the inclination angle of the inner wall of the blanking hopper 110. Because the inclination angle of the scraping plates 420 is the same as that of the blanking hopper 110, during the downward movement of the scraping disc 300, the surface of the scraping plates 420 can be attached to the inner wall of the blanking hopper 110. When the motor 400 drives the rotating rod 410 to rotate, the scraping plates 420 can rotate around the inner wall of the blanking hopper 110, thereby stirring the mortar raw materials remaining on the inner wall of the blanking hopper 110 and realizing the cleaning inside the blanking hopper 110. The scraping strips 430 at the bottom of the scraping plates 420 can extend into the blanking pipe 120, and when the scraping strips 430 rotate, the inside of the blanking pipe 120 can be cleaned.

[0029] On the top of the support plate 320, two sets of inclined hydraulic push rods 220 are symmetrically installed through two sets of hinge parts II 230. On the tops of the two sets of hydraulic push rods 220, hinge parts I 210 are installed. The two sets of hinge parts II 230 are symmetrically installed on both sides of the bottom of the top plate 200. By installing the support plate 320, the motor 400 can be installed below the support plate 320. And the two sets of hydraulic push rods 220 are connected to the scraping disc 300 through the support plate 320 and the support rod 310. When the two sets of hydraulic push rods 220 are opened, the support plate 320 can be pushed and pulled to move, realizing the adjustment of the height of the scraping disc 300. During the downward movement of the scraping disc 300, the residual mortar raw materials on the inner wall of the storage bucket 100 are pushed, achieving the cleaning effect on the inner wall of the storage bucket 100. At the same time, the scraping plate 420 and the scraping strip 430 can be correspondingly pushed into the feeding hopper 110 and the feeding pipe 120.

[0030] As an embodiment of the present utility model: During actual use, when the hydraulic push rod 220 pulls the scraping plate 420 to the upper side inside the storage bucket 100, mortar raw materials can be added into the storage bucket 100 through the feeding pipe 130 for storage. And when the valve inside the feeding pipe 120 is opened, the mortar raw materials can be discharged outwards. At this time, the hydraulic push rod 220 is opened, and the hydraulic push rod 220 extends to push the scraping disc 300 to move downward. During the movement of the scraping disc 300, the residual raw materials on the inner wall of the storage bucket 100 are pushed downward, realizing the cleaning of the inner wall of the storage bucket 100. At the same time, the rotating rod 410 can be pushed into the feeding hopper 110 and the feeding pipe 120, so that the surface of the scraping plate 420 is attached to the inner wall of the feeding hopper 110, and the scraping strip 430 is attached to the inner wall of the feeding pipe 120. At this time, the motor 400 is started. During the rotation of the motor, the scraping plate 420 and the scraping strip 430 are driven to rotate through the rotating rod 410, and then the mortar raw materials remaining in the feeding hopper 110 and the feeding pipe 120 are scraped, so that they are discharged downward through the feeding pipe 120, improving the utilization rate of the mortar raw materials and effectively reducing the residue of the mortar raw materials in the storage bucket 100, the feeding hopper 110 and the feeding pipe 120.

[0031] Please refer to Figure 2 , both the top plate 200 and the scraping disc 300 penetrate the upper surface to form a plurality of pressure relief holes. The top of the top plate 200 is fixed to the top of the storage bucket 100 by screws. The opening of the pressure relief holes can prevent the formation of negative pressure between the top plate 200, the scraping disc 300 and the bottom of the storage bucket 100 from affecting the use of the hydraulic push rod 220.

[0032] On the upper side of the outer surface of the feeding pipe 120, a collar 500 is installed. On the top of the collar 500, two sets of hydraulic rods 510 are symmetrically installed. The tops of the two sets of hydraulic rods 510 are respectively connected to both sides of the bottom of the top plate 200.

[0033] As the second embodiment of the present utility model, since the top plate 200 is fixed to the top of the storage barrel 100 by screws, and a hydraulic rod 510 is connected between the outside of the storage barrel 100 and the bottom of the top plate 200. When the screws are unscrewed, the hydraulic rod 510 is turned on. During the elongation process of the hydraulic rod 510, it can push the top plate 200 to move upward, so that the top plate 200 drives the hydraulic push rod 220, the motor 400, the scraping disc 300 and the rotating rod 410 to gradually move out of the storage barrel 100, which is convenient for the maintenance of the hydraulic push rod 220, the motor 400, etc., and avoids the formation of a closed space in the storage barrel 100 from affecting the device maintenance.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
