DETAILED DESCRIPTION

[0086] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0087] Figure 1 The structural diagram of a concrete production system provided by an exemplary embodiment of the present application is shown in FIG. Figure 1 As shown, the concrete production system 100 provided in the embodiment of the present application may include a discharge hopper 110 , a sand making assembly 120 , a mixing assembly 130 , a transfer bin 140 and a first conveying device 150 .

[0088] Specifically, the discharge hopper 110 can be used to receive materials unloaded by the engineering vehicle 200. For example, when sand making is required, the discharge hopper 110 can be used to receive sand making materials unloaded by the engineering vehicle 200; when concrete production is required, the discharge hopper 110 can be used to receive crushed stone unloaded by the engineering vehicle 200.

[0089] Specifically, the sand making component 120 can process the sand making raw materials to obtain finished sand, and the finished sand can be mixed with crushed stone and used as raw materials for subsequent concrete production.

[0090] Specifically, the mixing assembly 130 can process crushed stone and finished sand to produce concrete.

[0091] Specifically, the transfer bin 140 can be used to receive the finished sand output by the sand making component 120. That is to say, the finished sand produced by the sand making component 120 can be temporarily stored in the transfer bin 140 and then output from the transfer bin 140 when concrete production is needed.

[0092] Specifically, the first conveying device 150 may include a first receiving portion 151 and a second receiving portion 152. The first receiving portion 151 corresponds to the output portion of the discharge hopper 110. The first receiving portion 151 can receive the sand-making raw materials output from the output portion of the discharge hopper 110, and then convey the sand-making raw materials to the sand-making component 120; or, the first receiving portion 151 can receive the crushed stone output from the output portion of the discharge hopper 110, and then convey the crushed stone to the mixing component 130; the second receiving portion 152 corresponds to the output portion of the transfer bin 140, and the second receiving portion 152 can receive the finished sand output from the transfer bin 140, and then convey the finished sand to the mixing component 130.

[0093] The concrete production system 100 provided in the embodiment of the present application corresponds to the output part of the discharge hopper 110 through the first receiving part 151, and the second receiving part 152 corresponds to the output part of the transfer bin 140, so that the first conveying device 150 can be used to convey sand-making raw materials when sand-making operations are required; and the first conveying device 150 can be used to convey crushed stone and finished sand when concrete production operations are required. In other words, the concrete production system 100 provided in the embodiment of the present application uses the same set of first conveying devices 150 to achieve the function of transporting sand-making raw materials, finished sand and crushed stone. Compared with the solution of using two different conveying devices in the related art, it occupies a smaller area and has lower cost.

[0094] like Figure 1 As shown, the concrete production system 100 may further include a material detection device 160 . The material detection device 160 is disposed on the first conveying device 150 . The material detection device 160 may be used to detect the particle size of the material conveyed by the first conveying device 150 .

[0095] It should be understood that the particle size ranges of the sand making raw materials (such as pebbles), crushed stones and finished sand are respectively in different ranges. After the material detection device 160 outputs a signal representing the particle size of the material, the control system can determine the type of the current material by the particle size, thereby effectively controlling the corresponding sand making component 120 or stirring component 130 to start.

[0096] In one embodiment, the material detection device 160 may include an image acquisition sensor, an ultrasonic sensor, a laser sensor, etc.

[0097] like Figure 1 As shown, the first conveying device 150 may include a conveying main road 153, a first conveying branch road 154, a second conveying branch road 155 and a third conveying branch road 156. The first conveying branch road 154, the second conveying branch road 155 and the third conveying branch road 156 are all connected to the conveying main road 153, and the aforementioned first receiving portion 151 and the second receiving portion 152 are both arranged on the conveying main road 153. Correspondingly, the sand making component 120 includes a sand making raw material bin 121, and the mixing component 130 includes a finished sand bin 131 and a crushed stone bin 132. The sand making raw material bin 121 can be used to receive the sand making raw material output by the first conveying branch road 154, the finished sand bin 131 can be used to receive the finished sand output by the second conveying branch road 155, and the crushed stone bin 132 can be used to receive the crushed stone transported by the third conveying branch road 156.

[0098] In practical applications, when sand making is required, the first conveying device 150 is used to transport sand making raw materials. In this case, the main conveying road 153 can be connected to the first conveying branch road 154, and the sand making raw materials are transported from the discharge hopper 110 to the main conveying road 153, then to the first conveying branch road 154, and then enter the sand making raw material bin 121. When concrete production is required, the first conveying device 150 is used to transport finished sand and crushed stone. In the case of conveying finished sand, the main conveying road 153 can be connected to the second conveying branch road 155, and the finished sand is transported from the transfer bin 140 to the main conveying road 153, then to the second conveying branch road 155, and then enter the finished sand bin 131; in the case of conveying crushed stone, the main conveying road 153 can be connected to the third conveying branch road 156, and the crushed stone is transported from the discharge hopper 110 to the main conveying road 153, then to the third conveying branch road 156, and then enter the crushed stone bin 132.

[0099] In one embodiment, the switching action between the main conveying road 153 and the first conveying branch road 154, the second conveying branch road 155, and the third conveying branch road 156 can be adjusted in accordance with the detection signal of the aforementioned material detection device 160. Specifically, when the material detection device 160 detects that the range of the material particle size on the main conveying road 153 is within the particle size range of the sand making raw material, the system can control the main conveying road 153 to dock with the first conveying branch road 154; when the material detection device 160 detects that the range of the material particle size on the main conveying road 153 is within the particle size range of the finished sand, the system can control the main conveying road 153 to dock with the second conveying branch road 155; when the material detection device 160 detects that the range of the material particle size on the main conveying road 153 is within the particle size range of the crushed stone material, the system can control the main conveying road 153 to dock with the third conveying branch road 156.

[0100] In one embodiment, if the current material detection device 160 detects that the range of the material particle size on the main conveying road 153 is within the particle size range of the sand making raw material, and receives a concrete production instruction, it can wait until the material detection device 160 detects that the material particle size on the main conveying road 153 is less than a preset threshold value (at this time, it can be considered that there is no material being conveyed on the main conveying road 153, and the sand making raw material has been conveyed), and then execute the concrete production instruction, and the first conveying device 150 transports the finished sand and crushed stone required for concrete production, so that the materials can be effectively prevented from being mixed with each other. Similarly, if the current material detection device 160 detects that the range of the material particle size on the main conveying road 153 is within the particle size range of the finished sand or crushed stone, and receives a sand making instruction, it can wait until the material detection device 160 detects that the material particle size on the main conveying road 153 is less than a preset threshold value (at this time, it can be considered that there is no material being conveyed on the main conveying road 153, and the finished sand or crushed stone has been conveyed), and then execute the sand making instruction, and the first conveying device 150 transports the sand making raw material.

[0101] like Figure 1 As shown, the sand making component 120 may also include a crusher 122, a screener 123 and a second conveying device 124. When performing sand making operations, the sand making raw material bin 121 conveys the sand making raw material to the crusher 122. Since the particle size of the sand making raw material is relatively large, the crusher 122 can crush the sand making raw material to form a plurality of sand particles with smaller particle sizes. The plurality of sand particles with smaller particle sizes pass through the screener 123. The screener 123 can screen out sand materials with particle sizes that meet the requirements, i.e., finished sand. Then, the second conveying device 124 can convey the finished sand to the transfer bin 140. The transfer bin 140 temporarily stores the finished sand. When concrete production is required, the finished sand is conveyed to the first conveying device 150.

[0102] like Figure 1 As shown, the mixing assembly 130 may further include a third conveying device 133 and a mixing device 134. In the process of concrete production, the finished sand stored in the finished sand bin 131 and the crushed stone stored in the crushed stone bin 132 may be conveyed to the third conveying device 133. The third conveying device 133 conveys the finished sand and the crushed stone to the mixing device 134. The mixing device 134 mixes the finished sand and the crushed stone to produce concrete.

[0103] In one embodiment, the first conveying device 150 , the second conveying device 124 , and the third conveying device 133 may be a conveyor belt, a conveyor chain, a conveyor roller, or the like.

[0104] In one embodiment, the first conveying device 150 is a conveyor belt, and the first conveying branch 154, the second conveying branch 155 and the third conveying branch 156 are correspondingly diverter belts, which can be used to convey different materials to different warehouses.

[0105] Figure 2 The following is a schematic diagram of a feeding method provided by an exemplary embodiment of the present application. Figure 2 As shown, the feeding method provided in the embodiment of the present application can be applied to the concrete production system described in the above embodiment. Specifically, the feeding method may include:

[0106] S310: If a sand making instruction is received, control the first conveying device to convey the sand making raw materials to the sand making assembly.

[0107] S320: If a concrete production instruction is received, control the first conveying device to convey finished sand and crushed stone to the mixing assembly.

[0108] The feeding method provided in the embodiment of the present application uses the same set of first conveying devices to transport sand-making raw materials, finished sand and crushed stone. Compared with the solution of using two sets of different conveying devices in the related art, it occupies a smaller area and has lower cost.

[0109] It should be noted that step S310 and step S320 are parallel steps and there is no order of precedence.

[0110] Figure 3 A schematic diagram of a feeding method provided by another exemplary embodiment of the present application. Figure 3 As shown, the feeding method may further include:

[0111] S330: Obtain the particle size of the material conveyed by the first conveying device.

[0112] S340: Outputting a material signal indicating that the material is one of sand making raw material, crushed stone and finished sand according to the particle size.

[0113] S350: Control the operation of the sand making component or the mixing component according to the material signal.

[0114] Specifically, if step S310 is executed, and the particle size of the material detected is within the particle size range of the sand-making raw material, step S340 is executed, and a material signal indicating that the material is a sand-making raw material is output accordingly, and step S350 is executed to control the operation of the sand-making component; similarly, if step S320 is executed, and the particle size of the material detected is within the particle size range of the finished sand or crushed stone, step S341 is executed, and a material signal indicating that the material is a finished sand or crushed stone is output accordingly, and step S350 is executed to control the operation of the stirring component. In this way, the system can accurately control the operation of the sand-making component or the stirring component according to the particle size of the material, and avoid the occurrence of false triggering of the sand-making component or the stirring component.

[0115] Figure 4 A schematic diagram of a feeding method provided by another exemplary embodiment of the present application. Figure 4 As shown, after step S340, the feeding method may further include:

[0116] S360: If the material signal indicates that the current material is a sand making raw material and a concrete production instruction is received, the concrete production instruction is executed after the particle size is smaller than a preset threshold.

[0117] Specifically, if the material signal indicates that the current material is sand-making raw material, it can be considered that the sand-making instruction is currently being executed. In this case, if a concrete production instruction is received at this time, it is necessary to wait for the sand-making raw materials on the first conveying device to be transported, and then convey the crushed stone and finished sand required for concrete production. Otherwise, it is easy to cause the sand-making raw materials, crushed stone and finished sand to mix with each other, affecting the subsequent concrete production quality.

[0118] It should be noted that step S360 is executed to determine whether the sand-making raw materials on the first conveying device have been transported by checking whether the particle size is less than a preset threshold. Specifically, if the particle size is less than the preset threshold (the particle size detected under ideal conditions is zero), it can be considered that the materials on the first conveying device have been transported (there is no material being transported on the first conveying device), and then the concrete production instruction can be executed again to avoid mixing the sand-making raw materials, crushed stone, and finished sand. If the particle size is greater than or equal to the preset threshold, it can be considered that the first conveying device is still transporting the sand-making raw materials and needs to wait for the execution of the concrete production instruction.

[0119] It should be noted that the concrete production instruction can be understood as controlling the first conveying device to convey the finished sand and crushed stone to the mixing component and controlling the mixing component to work (ie, including executing step S350).

[0120] It should be understood that the preset threshold can be set according to actual conditions, and the embodiments of the present application do not specifically limit the preset threshold.

[0121] S370: If the material signal indicates that the current material is crushed stone or finished sand, and a sand-making instruction is received, the sand-making instruction is executed after the particle size is smaller than a preset threshold.

[0122] Similar to step S360, if the material signal represents crushed stone or finished sand, it can be considered that the concrete production instruction is currently being executed. In this case, if a sand making instruction is received at this time, it is necessary to wait for the crushed stone or finished sand on the first conveying device to be transported, and then convey the sand making raw materials required for the sand making operation. Otherwise, it is easy to cause the sand making raw materials, crushed stone and finished sand to mix with each other, affecting the subsequent sand making quality.

[0123] It should be noted that step S370 is executed to determine whether the crushed stone or finished sand on the first conveying device has been transported by checking whether the particle size is less than a preset threshold. Specifically, if the particle size is less than the preset threshold (the particle size detected under an ideal state is zero), it can be considered that the material on the first conveying device has been transported (the first conveying device has no more transported material), and then the sand making instruction can be executed again to avoid mixing the sand making raw materials, crushed stone, and finished sand. If the particle size is greater than or equal to the preset threshold, it can be considered that the first conveying device is still transporting crushed stone or finished sand, and it is necessary to wait for the sand making instruction to be executed.

[0124] It should be noted that the sand making instruction can be understood as controlling the first conveying device to convey the sand making raw materials to the sand making component and controlling the operation of the sand making component (ie, including executing step S350).

[0126] S311: Control the main conveying route to connect with the first conveying branch route.

[0127] S312: Control the main conveying route to convey the sand making raw materials to the first conveying branch route.

[0128] S313: Control the first conveying branch to convey the sand making raw materials to the sand making assembly.
