[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention installs a feeding bin ( Figure 2Position A in the middle is the installation position of the feeding bin), pour the material to be processed into the feeding bin, and then the material will enter the hollow barrel, and then two sets of spiral conveyors will rotate synchronously (one of which is used as a spare) to ensure that the material is smoothly dispersed to the entire screen surface of the filter shell, and the high-pressure fan can effectively remove large impurities. There are a total of four sets of filter shells, and the filtering effects inside the four sets of filter shells are different. The vibration motor can control the material for vibration filtration, and the precision temperature compensation electronic scale can monitor the weight of the material in real time. Whenever a certain type of material arrives at the corresponding outlet, it will automatically trigger the precision temperature compensation electronic scale in the weighing module to quickly and accurately determine the actual mass. When the filtration is completed, the controller will control the electric slide to operate, so that the four sets of electric slides The platform drives the corresponding filter shell to move. When it moves to the appropriate position, the auxiliary component runs and drives the stripping component to unload the material. At the same time, it can also prevent the material from failing to fall to the designated position. When the electric push rod drives the pressure rod to move downward, the stripping components inside the four groups of filter shells will all be opened, so that these materials will fall into the same designated position at the same time (specially used to store substandard mixed materials). The operator can use the touch screen on the surface of the controller to monitor all dynamic indicators and even remotely adjust any parameters to achieve full automated management. In addition, the system's built-in learning mechanism will continue to accumulate experience data and gradually improve its own control strategy, making the later operation more economical and environmentally friendly, achieving the effect of effectively improving the utilization efficiency of the device.

[0014] 2. When one end of the pressing plate is pushed, the pressing plate will rotate inside the pillar and pull the filter plate with the pillar as the fulcrum. During the pulling process, the pressing plate will slide inside the sliding shell to prevent it from getting stuck, so that the filter plate can be rotated downward and opened. The torsion spring is used to drive the filter plate to automatically reset and close after rotation. The filter plates inside the four groups of filter housings have four specifications from top to bottom: 8mm, 6mm, 4mm and 2mm, which can screen more cleanly and achieve the effect of facilitating the screening of materials of different specifications.

[0015] 3. When the filter material shell drives the connecting plate to move, the present invention pushes the sliding rod, thereby making the sliding rod slide inside the vertical plate, so that the pressure column follows the movement of the sliding rod and gets rid of the positioning of the inclined plate. At this time, the spring push rod will push the limit shell to move up on the surface of the material barrel. During the upward movement, the push column will push the pressure plate to rotate, and the limit shell will also be close to the lower end of the filter material shell, so that the material will not be scattered on the ground during unloading. There are a total of five groups of material barrels, which can be classified and placed according to the corresponding filter material shells, thereby effectively improving the efficiency of unloading.

DETAILED DESCRIPTION

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0019] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 7As shown, a concrete batching device with sand and gravel efficient screening and automatic distribution functions provided by an embodiment of the present invention comprises a bracket 1, an electric slide 3, an electric push rod 10 and a pressure rod 11, four groups of electric slides 3 are fixedly connected to one side of the surface of the bracket 1, the upper surfaces of the four groups of electric slides 3 are fixedly connected with precision temperature compensation electronic scales 2, the surfaces of the four groups of precision temperature compensation electronic scales 2 are movably connected with filter shells 13, the four groups of filter shells 13 are internally provided with stripping components 6, the two sides of the four groups of filter shells 13 are fixedly connected with vibration motors 12, the electric push rod 10 is fixedly connected to the middle of one side of the surface of the bracket 1, two groups of pressure rods 11 are fixedly connected to the piston end of the electric push rod 10, an auxiliary component 5 is arranged on the surface of the bracket 1, the auxiliary component 5 is used to prevent scattering during unloading, the stripping component 6 is used for automatic unloading, two groups of hollow barrels 7 are fixedly connected to the upper end of one side of the surface of the bracket 1, and screw conveyors 8 are arranged inside the two groups of hollow barrels 7, a high-pressure fan 9 is fixedly connected to one side of the surface of the bracket 1, and a controller 4 is fixedly connected to one side of the surface of the bracket 1.

[0021] Adopt the above scheme: when in use, a feeding bin is installed on the surface of the hollow barrel 7 ( Figure 2 Position A in the middle is the installation position of the feeding bin), the material to be processed is poured into the feeding bin, and then the material enters the hollow barrel 7, and then two sets of screw conveyors 8 rotate synchronously (one of which is used as a spare) to ensure that the material is smoothly dispersed to the entire screen surface of the filter shell 13, and the high-pressure fan 9 can effectively remove large impurities stuck on the screen surface. There are a total of four sets of filter shells 13, and the filtering effects inside the four sets of filter shells 13 are different. The vibration motor 12 can control the material to vibrate and filter, and the precision temperature compensation electronic scale 2 can monitor the weight of the material in real time. Whenever a certain type of material arrives at the corresponding outlet, it will automatically trigger the precision temperature compensation electronic scale 2 in the weighing module to quickly and accurately determine the actual mass. When the filtration is completed, the controller 4 will control the electric slide 3 to run. The four groups of electric slides 3 drive the corresponding filter shells to move. When they move to the appropriate position, the auxiliary component 5 runs and drives the stripping component 6 to unload the material, which can also prevent the material from failing to fall to the designated position. When the electric push rod 10 drives the pressure rod 11 to move downward, the stripping components 6 inside the four groups of filter shells will be opened. In this way, these materials will fall into the same designated position at the same time (specially used to store substandard mixed materials). The operator can use the touch screen on the surface of the controller 4 to monitor all dynamic indicators and even remotely adjust any parameters to achieve full-process automated management. In addition, the system's built-in learning mechanism will continue to accumulate experience data and gradually improve its own control strategy, making the later operation more economical and environmentally friendly, achieving the effect of effectively improving the efficiency of the device.

[0022] refer to Figure 3 , Figure 4 and Figure 6The stripping assembly 6 includes a filter plate 603, a rotating rod 602 and a sliding shell 605. The eight groups of rotating rods 602 are respectively fixedly connected to the inside of the four groups of filter material shells 13, and the surfaces of the eight groups of rotating rods 602 are sleeved with torsion springs 604; one side of the surface of the eight groups of torsion springs 604 is fixedly connected to the filter plate 603, and the lower surface of the eight groups of filter plates 603 is fixedly connected to two groups of sliding shells 605; both sides of the lower surface of the four groups of electric slides 3 are fixedly connected to pillars 607, and the inside of the two groups of pillars 607 are movably connected to a pressure plate 606, and one end of the pressure plate 606 is movably connected to the inside of the corresponding two groups of sliding shells 605, and one side of the surface of the four groups of filter material shells 13 is fixedly connected to a connecting plate 601.

[0023] The above scheme is adopted: when one end of the pressure plate 606 is pushed, the pressure plate 606 will rotate inside the pillar 607, and will pull the filter plate 603 with the pillar 607 as the fulcrum. During the pulling process, the pressure plate 606 will slide inside the sliding shell 605 to prevent it from getting stuck, so that the filter plate 603 can be rotated downward and opened. The torsion spring 604 is used to drive the filter plate 603 to automatically reset and close after rotation. The filter plates 603 inside the four groups of filter material shells 13 have four specifications of 8mm, 6mm, 4mm and 2mm from top to bottom, which can screen more cleanly and achieve the effect of facilitating the screening of materials of different specifications.

[0024] refer to Figure 7 The auxiliary component 5 includes a material barrel 509, a limiting shell 507, a top column 501 and a vertical plate 502. The five groups of material barrels 509 are fixedly connected to the bottom of the bracket 1, and the four groups of limiting shells 507 are respectively slidably connected to the surfaces of four groups of material barrels 509; several groups of top columns 501 are respectively fixedly connected to the upper surfaces of the four groups of limiting shells 507, and two groups of spring top rods 508 are commonly fixedly connected between the four groups of limiting shells 507 and the bracket 1; an inclined plate 506 is fixedly connected to one side of the upper surface of the four groups of limiting shells 507, and the four groups of vertical plates 502 are fixedly connected to the upper surface of the bracket 1; a sliding rod 503 is slidably connected to the inside of one end of the four groups of vertical plates 502, and the surfaces of the four groups of sliding rods 503 are all sleeved with telescopic springs 504, and the lower surfaces of the four groups of sliding rods 503 are fixedly connected with pressure columns 505.

[0025] The above scheme is adopted: when the filter shell drives the connecting plate 601 to move, it will push the sliding rod 503, so that the sliding rod 503 slides inside the vertical plate 502, so that the pressure column 505 follows the movement of the sliding rod 503 and gets rid of the positioning of the inclined plate 506. At this time, the spring push rod 508 will push the limiting shell 507 to move up on the surface of the material bucket 509. During the upward movement, the push column 501 will push the pressure plate 606 to rotate, and the limiting shell 507 will also be close to the lower end of the filter shell 13, so that the material will not be scattered on the ground during unloading. A total of five groups can be used for the material bucket 509, which can be classified and placed according to the corresponding filter shell 13, thereby effectively improving the efficiency of unloading.

[0026] Working principle of the present invention: When in use, when one end of the pressing plate 606 is pushed, the pressing plate 606 will rotate inside the pillar 607, and will use the pillar 607 as a fulcrum to pull the filter plate 603. During the pulling process, the pressing plate 606 will slide inside the sliding shell 605 to prevent it from getting stuck, so that the filter plate 603 can be rotated downward and opened. The torsion spring 604 is used to drive the filter plate 603 to automatically reset and close after rotation. The filter plates 603 in the four groups of filter material shells 13 have four specifications of 8mm, 6mm, 4mm and 2mm from top to bottom, which can screen more cleanly. When the filter material shell drives the connecting plate 601 to move, The slide bar 503 will be pushed, so that the slide bar 503 slides inside the vertical plate 502, and the pressure column 505 will follow the movement of the slide bar 503 and get rid of the positioning of the inclined plate 506. At this time, the spring push rod 508 will push the limiting shell 507 to move up on the surface of the material bucket 509. During the upward movement, the push column 501 will push the pressure plate 606 to rotate, and the limiting shell 507 will also be close to the lower end of the filter material shell 13. This will prevent the material from being scattered on the ground during unloading. A total of five groups can be used for the material bucket 509, which can be classified and placed according to the corresponding filter material shell 13.
