Therefore, the market gap is gradually filled by manufactured sand, and there is a trend to replace natural sand. The overall investment and development prospect of artificial manufactured sand is relatively broad. As the name implies, manufactured sand refers to sand processed artificially, mainly including two categories: manufactured sand and mixed sand. Manufactured sand is rock particles with a particle size less than 4.75 mm made from rocks, pebbles, etc. through processes such as soil removal, mechanical crushing, shaping, and screening. Mixed sand is a mixture of manufactured sand and natural sand in a certain proportion.

[0003] For existing efficient discharging devices for manufactured sand, generally, normal vehicle-mounted unloading is used to complete the discharging of manufactured sand. The overall transportation efficiency and discharging effect are relatively good. However, with the continuous development of the modernization process, the requirements for discharging devices are no longer limited to discharging only. In particular scenarios, the discharging methods are also different. Especially when existing manufactured sand discharging devices are discharging, they cannot well control the humidity of manufactured sand and perform drying treatment, resulting in certain impacts on the overall consistency of the concrete during subsequent mixing, increasing the setting time, and the overall discharging is uneven, and the integration of screening and output is not high, failing to achieve the ideal use effect.

[0020] Working principle: When using an artificial sand high-efficiency discharging device provided by the present invention, the specific operation steps are as follows:

[0021] First step: First, connect the conveying pipeline through the double-pipe feeding port for artificial sand, or replace it with the feeding port to convey the artificial sand. Then start the servo motor. The servo motor drives the first middle connecting rod and the first gear thereon to rotate synchronously. During the rotation stage, the ring wall plate connected to the rack ring is driven to rotate through the meshing relationship with the rack ring, so that the ring wall plate drives the stirring block connected to itself to rotate in the mixing ring box, and then cooperates with the ring groove column fixed in the mixing ring box for static and dynamic cooperation stirring, so that the artificial sand is in a loose and mixed conveying state;

[0022] Second step: During the stirring process of the first step, local heating is carried out by using the heater on the ring groove column, and then combined with the heating plate in the stirring block for local heating, and it is also in a state of combining static and dynamic, and the heat transfer is more uniform. And the humidity detector arranged on the ring groove column can detect the wet water content of the artificial sand. With the accurate display and control of the control panel, the intelligent humidity control of the artificial sand is realized, which is convenient for the overall concrete mixing quality not to be weakened due to excessive wetness during the concrete mixing stage, indirectly shortening the mixing time and improving the mixing operation efficiency;

[0023] Step 3: Meanwhile, the rotation of the rack ring also drives the rotation of the second gear engaged with the lower part and the second middle connecting rod connected to the second gear. Then, through the second middle connecting rod, the first driving wheel on the outside connected thereto is synchronously driven to rotate. The first driving wheel then uses the first belt to synchronously drive the first driven wheel to rotate, so that the first driven wheel drives the third gear to rotate. With the driving force of one full rotation of the rack ring, the driving force is converted. Moreover, the rotating first driven wheel drives the engaged external tooth ring to perform a planetary rotation, so that the sliding ring connected to the inner side of the external tooth ring rotates in the outer space formed by the first middle connecting rod, the outer wall ring and the second gear. And there is a fan blade plate connected to the inner side of the sliding ring in the space to perform a planetary rotation therein, thus forming a planetary fan. And the external air is inhaled by using this rotational force through the air inlet interface, so as to utilize this air flow;

[0024] Step 4: The inhaled air then reaches the air delivery channel through the rotation of the fan blade plate and is discharged into the noise reduction box through the air delivery channel. Due to the continuous rotating thrust of the fan blade plate, the discharged air starts to be conveyed. First, it enters the air inlet flare and the air is subjected to the first step of noise reduction through the sound absorption ring. Then the air flows to the sound absorption cone, and the flow direction is limited through the action of the sound absorption cone and the gas guide plates on both sides, which is also convenient for making full use of the sound absorption cone for noise reduction. The discharged air is pressurized by the ventilator and then discharged into the mixing ring box through the delivery air pipe. At this time, the mixing ring box is in a state of stopping heating. By continuously introducing natural wind and stirring, it is dried more thoroughly, which is convenient for jointly controlling the humidity with heating, and at the same time, it speeds up the cooling and discharging of the artificial sand;

[0025] Step 5: The processed artificial sand is discharged through the stirring action and the discharge channel. And when discharging, due to the height difference, it will hit the striking rod to make it dispersed, which is convenient for subsequent screening. The fallen artificial sand is then screened by the screening structure as follows: The driving motor drives the second driving wheel to rotate. The second driving wheel drives the second driven wheel through the second belt. The second driving wheel and the second driven wheel then drive the connected convex block turntable to rotate, so as to intermittently strike the link structure composed of the lower slider, the connecting rod and the upper slider. And relying on the connection action of the spring, the inclined filter plate connected thereto is driven to perform vertical displacement screening. The screened fine sand drops, and the coarse sand rolls into the coarse material receiving box for collection. The opening of the coarse material receiving box is driven by the hydraulic rod to drive the material port blocking plate to expand and contract to open;

[0026] Step 6: The dropping point of the falling fine sand is on the first conveying device. The magnetic tape installed on the first conveying device adsorbs the residual metal substances in the fine sand. At the same time, the first conveying device drives the fine sand thereon to move forward and enter the second conveying device. The metal impurities magnetically adsorbed by the magnetic tape will rotate to the lower part and be scraped off and collected by the scraper on the bottom box. The fine sand conveyed away by the second conveying device is further loosened by the rotating loose roller shaft and finally discharged through the inclined discharge port to complete the efficient unloading process of artificial sand.

[0027] The present invention provides an efficient unloading device for artificial sand, having the following beneficial effects:

[0028] 1. By using the stirring block and the annular groove column for static and dynamic cooperative stirring, the artificial sand is in a loose and mixed conveying state. The heater on the annular groove column is used for local heating, and the heating plate in the stirring block is used for local heating in combination, and it is also in a heating state of combining static and dynamic, so that the heat transfer is more uniform. The humidity detector set on the annular groove column can detect the wet water content of the artificial sand. With the accurate display and control of the control panel, the intelligent humidity control of the artificial sand is realized, which is convenient for preventing the overall concrete mixing quality from being weakened due to excessive wetness during the concrete mixing stage, indirectly shortening the mixing time and improving the mixing operation efficiency.

[0029] 2. By the rotation of the fan blade plate, external air is absorbed, and the intake air expansion port and the sound absorption ring in the noise elimination box are used for the first step of sound absorption of the air. Subsequently, the flow direction is limited by the sound absorption cone and the gas guide plates on both sides. While fully using the sound absorption cone for sound absorption, the discharged air can also be pressurized by the ventilator and discharged into the mixing ring box through the conveying air duct. By continuously introducing natural wind and stirring, it is dried more fully, which is convenient for jointly controlling the humidity with heating and also accelerating the cooling and discharging of the artificial sand.

[0030] 3. The driving motor drives the second driving wheel to rotate. The second driving wheel drives the second driven wheel through the second belt. The second driving wheel and the second driven wheel drive the connected convex block turntable to rotate, thereby intermittently hitting the connecting rod structure composed of the lower sliding block, the connecting rod and the upper sliding block. And relying on the connection effect of the spring, the inclined filter plate connected thereto is driven to perform up and down displacement screening, which is convenient for the subsequent selection of fine and coarse materials.

[0056] Specifically, the inhaled air then reaches the air delivery channel 302 through the rotation of the fan blade plate 219 and is discharged into the noise reduction box 301 through the air delivery channel 302. Due to the thrust of the continuous rotation of the fan blade plate 219, the discharged air starts to be conveyed. First, it enters the intake flare 305, and the first-stage noise reduction of the air is carried out through the sound insulation ring 306. Subsequently, the air flows to the sound insulation cone 308, and the flow direction is restricted by the action of the sound insulation cone 308 and the gas guide plates 307 on both sides, which also facilitates the full utilization of the sound insulation cone 308 for noise reduction. After the discharged air is pressurized by the ventilator 303, it is discharged into the mixing ring box 201 through the delivery air duct 304. At this time, the mixing ring box 201 is in a state of stopping heating. By continuously introducing natural wind and stirring, it can be dried more thoroughly, which is convenient for jointly controlling the humidity with heating, and at the same time, it speeds up the cooling and discharging of artificial sand.
