Description

Technical Field

[0001] The invention relates to the technical field of raw material transportation, in particular to a cement concrete production device with a continuous feeding function. Background Art

[0002] Concrete generally refers to cement as the binder and sand and stone as aggregates mixed in a certain proportion. It is one of the main materials for civil engineering.

[0003] Traditional concrete mixing relies on manual labor. With the continuous development of science and technology, it has mainly transformed into semi-automatic production, and now it is automated proportioning production. In the large-scale production of concrete, automated production is mostly used. However, since the raw materials of concrete are mostly powder or fine particles, when they are sent to the mixing tank for mixing, the raw materials need to be transported from a lower position to a higher position. When conveying these powders, traditional conveying devices mostly rely on the friction of the powders themselves. Once there is a large vibration during the conveying process, it will interfere with the feeding efficiency and reduce the conveying efficiency.

[0004] In addition, in large-scale production of concrete, multiple materials are generally loaded separately for automated proportioning. The friction of the raw materials themselves will affect the feeding efficiency, causing fluctuations in the instantaneous feeding volume, affecting the proportioning accuracy, and ultimately may reduce the setting strength of the concrete itself and affect its service life. Summary of the invention

[0005] The purpose of the present invention is to provide a cement concrete production device with a continuous feeding function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: A cement concrete production device with a continuous feeding function, the production device comprises a supporting device, an adjusting device, a guide device and a silo, the supporting device is connected to the adjusting device, a guide device is provided at the lower end of the silo, the silo and the guide device are connected by pipelines, the silo and the supporting device are tightly connected, the supporting device comprises a conveyor belt, and the adjusting device is used to adjust the local feeding speed of the conveyor belt.

[0007] The production device is used to transport cement concrete raw materials. The supporting device serves as the main installation basis for installing and fixing other devices. The silo is used to output cement concrete raw materials, which are guided to subsequent workstations for processing through the supporting device. The adjusting device is set to ensure a stable supply of raw materials. The guide device is used to guide the discharge of materials from the silo. According to the fluctuation of the discharge amount of the silo, the local feeding speed of the conveyor belt is adjusted by the adjusting device to facilitate subsequent processing.

[0008] Furthermore, the supporting device also includes a bracket and a driving motor, the driving motor and the bracket are tightly connected, a conveying roller is provided at the output end of the driving motor, a feeding trough is provided on the bracket, the conveyor belt is arranged along the feeding trough, two conveying rollers are provided, the two conveying rollers are respectively placed on both sides of the inner circle of the conveyor belt, the conveying rollers and the feeding trough are rotatably connected, and the flow guide device includes a connecting pipe, the upper end of the connecting pipe is connected to the silo outlet; Guide grooves are respectively arranged on both sides of the feeding trough, and the adjusting device comprises a carrier plate, one side of the carrier plate is tightly connected to the conveyor belt, the lower end of the connecting pipe faces the carrier plate, the conveyor belt is arranged inclined, and the carrier plate is in a horizontal state when loading materials.

[0009] The conveyor belt is guided by the feeding trough on the bracket, and continuous feeding is carried out through the conveyor belt. The driving motor is the main power component, and the shell is fixed on the bracket. The output torque drives the conveyor roller to rotate. The two conveyor rollers rotate on a fixed axis in the feeding trough. During the rotation process, they are in friction contact with the inner ring of the conveyor belt, driving the conveyor belt to rotate, thereby transporting cement concrete. A connecting pipe is set at the lower end of the silo for discharging. In order to meet the needs of subsequent processing, the feeding process of the conveyor belt is an upward process, and inclined feeding is carried out through the carrier plate set on the conveyor belt and the horizontal feeding setting of the carrier plate. When the raw materials transported by the connecting pipe fall on the carrier plate, it is beneficial to control the feeding accuracy of a single carrier plate. When powder feeding is performed, the influence of vibration on feeding is reduced, and the feeding efficiency is improved.

[0010] Furthermore, the carrier plate includes a bottom plate and a movable plate, one side of the bottom plate is tightly connected to the conveyor belt, a movable groove is provided on the bottom plate, the movable plate and the movable groove are slidably connected, an induction groove is provided at the bottom of the movable groove, the adjustment device also includes a differential assembly, the differential assembly includes a preload spring and a magnetic column, the movable plate and the magnetic column are tightly connected, the lower end of the magnetic column is abutted against the induction groove through the preload spring, a differential coil is provided in the induction groove, and the differential coil is placed on the outer ring of the magnetic column.

[0011] The carrier plate is designed in a split style. The bottom plate serves as the bearing base and is connected to the conveyor belt. The movable plate is slidably guided by the movable groove. When the raw materials transported by the connecting pipe fall on the movable plate, the movable plate will be driven to move downward, thereby further compressing the preload spring through the magnetic column. During the movement of the magnetic column, the differential coil on the outer ring cuts the magnetic flux lines and generates an induced current. The more material is loaded, the more magnetic flux lines are cut by the differential coil, and the greater the induced current generated. That is, the size of the induced current is positively correlated with the amount of material loaded on the movable plate, thereby performing real-time detection of the loading amount.

[0012] Furthermore, the adjusting device also includes a plurality of transmission seats, which are located between adjacent carrier plates, and the transmission seats are slidably connected to the guide grooves, and a differential cavity is provided on the transmission seat. The differential assembly also includes a fixed roller and a movable roller, which are respectively placed in the differential cavity, and the fixed roller is rotatably connected to the differential cavity, and the movable roller is slidably connected to the differential cavity. A slide groove is provided on the outside of the differential cavity, and a telescopic cylinder is provided in the slide groove, and the output end of the telescopic cylinder abuts against the movable roller. A reversing camber surface is provided at the front end of the differential cavity close to the feeding direction, and the movable roller and the fixed roller are arranged in sequence along the feeding direction, and the conveyor belt is arranged in an "S" shape along the fixed roller and the movable roller, and the conveyor belt is in friction contact with the reversing camber surface.

[0013] The transmission seat is slidably guided by the guide groove. The transmission seat is located between two adjacent carrier plates. The length of the conveyor belt between the two adjacent carrier plates is adjusted by the differential assembly. Therefore, when loading, the relative residence time of the carrier plate at the lower end of the connecting pipe is adjusted, that is, the loading time is adjusted to control the loading amount. The movable roller and the fixed rotating roller are built into the differential cavity. The fixed rotating roller rotates on a fixed axis in the differential cavity. The movable roller also rotates under the friction contact of the conveyor belt. The telescopic cylinder is fixed by the slide grooves on both sides. The output end of the telescopic cylinder abuts against the outer side of the movable roller. The movable roller The movable plate at the lower end of the connecting tube maintains a certain distance from the fixed roller under the action of the conveyor belt tension. When the movable plate at the lower end of the connecting tube is loaded with too much material instantaneously, the telescopic cylinder on the upper side outputs displacement, driving the movable roller to move away from the feeding direction, that is, extending the distance between the movable roller and the fixed roller, accelerating the instantaneous movement speed of the movable plate at the loading station, and reducing the loading time. The conveyor rollers on both sides rotate on a fixed axis, and the distance between the two remains unchanged. When the conveyor belt on the upper side shrinks, the telescopic cylinder at the lower end drives the movable roller to retract, reducing the distance between the movable roller and the fixed roller, and performing length compensation.

[0014] Furthermore, two driving motors are provided, and the two conveying rollers are not in frictional contact with the portion of the conveying belt close to the transmission seat at the same time.

[0015] By setting two driving motors to drive the two conveying rollers respectively with the same angular velocity, the feeding efficiency is improved. Only one conveying roller will contact the conveyor belt close to the transmission seat at a time, thereby ensuring the transmission efficiency.

[0016] Furthermore, the differential coil is electrically connected to two adjacent telescopic cylinders respectively, and the output displacement directions of the two adjacent telescopic cylinders are opposite.

[0017] The differential coil is electrically connected to the upper and lower telescopic cylinders respectively. When too much material is loaded instantaneously, the telescopic cylinder at the upper end outputs displacement, which speeds up the movable plate of the loading station and retracts the telescopic cylinder at the lower end to compensate for the length. Conversely, when too little material is loaded instantaneously, the telescopic cylinder at the upper end retracts to reduce the local conveying speed.

[0018] As an optimization, a limit plate is provided at the lower end of the bottom plate near the conveyor belt, and the side of the limit plate abuts against the surface of the conveyor belt. By providing the limit plate, the bottom plate abuts against the surface of the conveyor belt through the limit plate, increasing the support area, dispersing stress, and improving the conveying stability.

[0019] Furthermore, the guide device also includes a guide paddle and a rotary motor. A dispersion chamber is provided in the connecting pipe. The guide paddle and the dispersion chamber are rotatably connected. The upper end of the dispersion chamber is connected to the silo, and the lower end faces the movable plate. A gear ring is provided on the outer ring of the central axis of the guide paddle. A driving chamber is provided on one side of the dispersion chamber. The rotary motor is placed in the driving chamber. A gear is provided at the output end of the rotary motor. The rotary motor is transmission-connected to the guide paddle through the meshing of the gear and the gear ring.

[0020] The dispersion chamber has a built-in guide paddle, including a central shaft, a gear ring and paddles. The central shaft and the gear ring are fixedly connected. The gear is driven by a rotary motor in the driving chamber to rotate. The tooth surface engages, thereby driving the guide paddle to rotate along a fixed axis. During the rotation of the guide paddle, the material is discharged downward to increase the feeding rate.

[0021] As an optimization, the guide paddle blades are arranged in a spiral, and the pitch of the guide paddle blades gradually increases from top to bottom. Through the gradual pitch setting, when the raw materials in the upper pitch are transferred to the lower pitch, the space is increased, so that the raw materials are dispersed, which is convenient for subsequent processing.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the feeding process of the conveyor belt is an upward process, and the feeding is carried out at an angle. Through the carrier plate arranged on the conveyor belt and the horizontal feeding setting of the carrier plate, when the raw material transported by the connecting pipe falls on the carrier plate, it is beneficial to control the feeding accuracy of a single carrier plate, and when powder feeding is performed, the influence of vibration on the feeding is reduced, and the feeding efficiency is improved; when the raw material transported by the connecting pipe falls on the movable plate, the movable plate will be driven to move downward, thereby further compressing the preload spring through the magnetic column. During the movement of the magnetic column, the differential coil of the outer ring cuts the magnetic flux lines and generates an induced current. The more the material is fed, the more magnetic flux lines are cut by the differential coil, and the greater the induced current generated, that is, the size of the induced current and the movable plate The feeding amount is positively correlated, so the feeding amount can be detected in real time; the conveyor belt length between two adjacent carrier plates is adjusted by the differential component, so that when feeding, the relative residence time of the carrier plate at the lower end of the connecting tube is adjusted, that is, the feeding time is adjusted to control the feeding amount; when the movable plate located at the lower end of the connecting tube is overloaded instantaneously, the telescopic cylinder on the upper side outputs displacement, driving the movable roller to move away from the feeding direction, that is, extending the distance between the movable roller and the fixed rotating roller, accelerating the instantaneous movement speed of the movable plate at the feeding station, reducing the feeding time, and the conveyor rollers on both sides rotate with a fixed axis, and the distance between the two remains unchanged. When the conveyor belt on the upper side shrinks, the telescopic cylinder at the lower end drives the movable roller to retract, reducing the distance between the movable roller and the fixed rotating roller, and performing length compensation.

The movable plate 212 is slidably guided by the movable groove 2112. When the raw materials transported by the connecting tube 33 fall on the movable plate 212, the movable plate 212 is driven to move downward, thereby further compressing the preload spring 231 through the magnetic column 232.

The more the material is fed, the more the magnetic flux lines cut by the differential coil 233, and the greater the induced current generated, that is, the magnitude of the induced current is positively correlated with the feeding amount of the movable plate 212. The feeding amount can be detected in real time; the length of the conveyor belt 14 between two adjacent carrier plates 21 is adjusted by the differential assembly 23, so that when feeding, the relative residence time of the carrier plate 21 at the lower end of the connecting tube 33 is adjusted, that is, the feeding time is adjusted to control the feeding amount; when the movable plate 212 located at the lower end of the connecting tube 33 is overloaded instantaneously, the telescopic cylinder 234 on the upper side outputs displacement, driving the movable roller 236 to move away from the feeding direction, that is, extending the distance between the movable roller 236 and the fixed rotating roller 235, accelerating the instantaneous movement speed of the movable plate 212 of the feeding station, reducing the feeding time, and the conveyor rollers 12 on both sides rotate on a fixed axis, and the distance between the two remains unchanged.
