In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0042] In the prior art, the crushing and conveying system of koji powder adopts an upper and lower two-layer structure. Due to height restrictions, the crushing part is generally set in a foundation pit. An air delivery pipe is placed in the foundation pit to transport the crushed koji powder, and the koji powder is separated by a cyclone separator. The setting of the bottom foundation pit here may prolong the construction time and increase the investment cost. And because the setting of the air delivery pipe is large and complicated, the required fan air volume and power are large, which may cause a lot of noise and have a certain impact on the surrounding environment. Therefore, the embodiment of the present application provides a koji block crushing and conveying system. Through the cooperation of the three modules of the crushing module, the conveying module and the packaging module, the crushing and transportation of the koji blocks can be realized, and there is no need to excavate the foundation pit, which is convenient for construction, saves construction time, and saves investment costs. And because the entire crushing and conveying system is a closed production, there is no dust spillage, which can ensure a good working environment.

[0043] The following is a detailed description of a block crushing and conveying system provided in this embodiment in conjunction with the accompanying drawings. Figure 1 , Figure 2 As shown, it includes: a crushing module 1, a conveying module 2 and a packaging module 3, and the crushing module 1, the conveying module 2 and the packaging module 3 are arranged in a four-layer upper and lower structure; the crushing module 1 is arranged on the fourth floor and is connected with the feeding port arranged on the fifth floor, and is used for crushing the koji blocks dropped from the feeding port to obtain koji powder; the conveying module 2 is arranged on the third floor and is connected with the crushing module 1, and is used for sorting the koji powder dropped from the crushing module 1 and then conveying it to the packaging module 3; the packaging module 3 is arranged between the first floor and the second floor through the floor, and is connected with the conveying module 2, and is used for weighing and packaging the koji powder dropped from the conveying module 2 for easy transportation.

[0044] Specifically, after the staff puts the koji block into the feeding port of the fifth floor, the koji block enters the crushing module 1 through the feeding port. The crushing module 1 is arranged on the fourth floor with a floor height of about 4.5 meters, and the koji block can be crushed to obtain koji powder; the conveying module 2 is arranged at the lower end of the third floor, i.e., the crushing module 1. The floor height of the third floor is also 4.5 meters, and the lower end of the crushing module 1 is connected to a discharge buffer pipe 5, and the koji powder can enter the conveying module 2 through the discharge buffer pipe 5. After the conveying module 2 separates the koji powder, it controls it to fall into the packaging module 3; the packaging module 3 is arranged between the first floor and the second floor through the floor, and the floor height of the first floor and the second floor are both about 5 meters. The packaging module 3 can weigh and pack the koji powder falling from the conveying module 2, so as to facilitate the subsequent transfer and transportation of the koji powder by the transfer vehicle.

[0045] The above operation, through the cooperation of the crushing module, the conveying module and the packaging module, can realize the crushing and transportation of the curved blocks, without the need to excavate the foundation pit, thus achieving the effect of facilitating construction, saving construction time and saving investment costs. Moreover, since the entire crushing and conveying system is a closed production system, there is no dust spillage, which can ensure a good working environment.

[0046] In one embodiment, referring to Figure 1 As shown, the koji block crushing and conveying system also includes a dust removal module 4; the dust removal module 4 runs through the overall upper and lower four-layer structure, and is used to remove dust and cool the koji powder at the conveying module 2 and the packaging module 3.

[0047] Here, the koji block crushing and conveying system is also provided with a dust removal module 4, which runs through the overall upper and lower four-layer structure, so as to facilitate dust removal and cooling operations on the koji powder at the conveying module 2 and the packaging module 3, so as to achieve the effect of improving air quality and protecting the ecological environment, and the koji powder dust placed in the dust removal module 4 can also fall into the conveying module 2 again to realize the recycling of the koji powder.

[0048] In one embodiment, continue to refer to Figure 1 , Figure 2 As shown, the crushing module 1 includes a primary crushing part 11 and a secondary crushing part 13; the primary crushing part 11 is arranged on the fourth layer and is connected to the feeding port, and is used for performing primary crushing on the koji blocks falling from the feeding port to obtain koji powder of the first particle size; the secondary crushing part 13 is arranged on the fourth layer and is connected to the primary crushing part 11, and is used for performing secondary crushing on the koji powder of the first particle size falling from the primary crushing part 11 to obtain koji powder of the second particle size.

[0049] Here, the primary crushing part 11 may adopt a claw crusher 111 , and the secondary crushing part 13 may adopt a hammer crusher 131 .

[0050] Specifically, the claw crusher 111 is arranged on the middle platform of the fourth floor. This platform can be a concrete structure or a steel structure, as long as the bearing strength can be guaranteed. The claw crusher 111 is connected to the feeding port arranged on the fifth floor. The koji blocks enter the claw crusher 111 through the feeding port to achieve the primary crushing of the koji blocks, thereby obtaining koji powder of the first particle size. Among them, the crushing mechanism of the claw crusher 111 is mainly composed of a pair of claw-shaped rollers horizontally installed on the frame in parallel with each other. The front claws and the rear claws rotate towards each other during operation. The koji blocks enter the feeding box of the claw crusher 111 and are crushed by the tearing, shearing and other actions of the front and rear claws. The crushed koji blocks are pushed out by the claws and discharged downward. Therefore, the crushing operation is carried out continuously and has the effect of forced unloading. Therefore, the crushed koji powder will not cause blockage to the claw crusher 111.

[0051] The hammer crusher 131 is arranged on the ground of the fourth floor and is located at the lower end of the claw crusher 111. It is connected to the claw crusher 111 and can crush the first particle size koji powder to obtain the second particle size koji powder. Here, the first particle size koji powder falls from the lower end of the claw crusher 111 by gravity, enters the top feed port of the hammer crusher 131, enters the crushing chamber of the hammer crusher 131 through the fixed feed guide plate, and contacts the top of the high-speed rotating hammer. Based on the speed difference between the first particle size koji powder and the hammer, the first particle size koji powder is crushed. The crushed particles collide with each other on the screen and the hammer anvil of the hammer crusher 131, and then accelerate and rub against the screen, and are finally gradually crushed. When the diameter of the crushed koji powder particles is smaller than the sieve hole, they pass through the sieve hole under the action of centrifugal force and airflow and are discharged from the base discharge port to obtain the second particle size koji powder.

[0052] It should be noted that the crushing module 1 is placed high here, all on the fourth floor, and a combination mode of two-level crushing of the claw crusher 111 and the hammer crusher 131 is adopted to form a reasonable crushing and grading. The size of the koji block is about 370×280×130mm, which is relatively large and brittle. The claw crusher 111 has good applicability and can quickly and effectively crush the koji blocks by tearing and shearing. The impact load of the koji blocks when they fall can be reduced through its own belt drive. After crushing by the claw crusher 111, koji powder with a particle size of 40-50mm, i.e., the first particle size koji powder, can be obtained. The first particle size koji powder falls into the hammer crusher 131 and is crushed by the hammer crusher 131 to obtain koji powder with a particle size of less than 4mm, i.e., the second particle size koji powder. The hammer crusher 131 here is more suitable for crushing dry materials. It has the effects of large production capacity, large crushing ratio, low power consumption, simple mechanical structure and convenient maintenance. The claw crusher 111 and the hammer crusher 131 are used in combination to make the obtained koji powder particle size more in line with the requirements.

[0053] In one achievable manner, continue to refer to Figure 1 , Figure 2 As shown, the crushing module 1 also includes a material sorting and iron removal section 12; the material sorting and iron removal section 12 is located between the primary crushing section 11 and the secondary crushing section 13, and is used to sort and remove iron from the first particle size koji powder falling from the primary crushing section 11, and control the first particle size koji powder after sorting and iron removal operations to fall into the secondary crushing section 13.

[0054] The material separation and iron removal section 12 may adopt a material separation and iron removal device 121 .

[0055] Specifically, the classifier iron remover 121 is also arranged on the fourth floor, between the claw crusher 111 and the hammer crusher, that is, the claw crusher 111, the classifier iron remover 121 and the hammer crusher 131 are arranged in order from top to bottom. The classifier iron remover 121 is arranged in a herringbone shape, so two hammer crushers 131 can be set, and the upper end of the classifier iron remover 121 can be fixedly connected with the claw crusher 111 through a flange, and the lower end of the classifier iron remover 121 can be fixedly connected with the two hammer crushers 131 through flanges. After the koji powder is crushed by the claw crusher 111 to obtain the first particle size koji powder, the first particle size koji powder can be firstly allowed to enter the classifier iron remover 121, and the classifier and iron removal operations are performed on it. After the classifier and iron removal operations are completed, the first particle size koji powder is allowed to fall into the hammer crusher 131 for secondary crushing. There is an adjustment angle indicator on the outside of the material separation and iron removal device 121, and the staff can adjust the material separation operation based on the indicator. The material separation and iron removal device 121 can make the koji powder flow to the designated iron removal bin according to the working conditions of the lower end equipment. The strong magnet in the iron removal bin can absorb metal objects and prevent them from entering the hammer crusher 131, thereby achieving the purpose of material separation and iron removal, and the iron impurities need to be manually cleaned after a period of accumulation.

[0056] It should be noted that the reason why the classifying and iron removing device 121 is added here is that after the koji powder is crushed by the claw crusher 111, it needs to enter the hammer crusher 131 for secondary crushing. However, the rotation speed of the hammer crusher 131 is relatively high, reaching 3000r / min. If iron impurities collide with the hammer, sparks may be generated to cause an explosion. Therefore, the classifying and iron removing device 121 can be added here to remove the iron impurities.

[0057] The setting of the above-mentioned crushing module 1, by placing the crushing module 1 high, can achieve the purpose of crushing the curved blocks while allowing the noise generated by it to propagate upwards, thereby providing a good environment for the workshop office and operation room on the ground floor, and no foundation pit excavation is required, thereby achieving the effect of facilitating construction, saving construction time, and saving investment costs.

[0058] In one embodiment, continue to refer to Figure 1 , Figure 2As shown, the conveying module 2 includes a spiral conveying unit 21 and a control gate valve 22; the spiral conveying unit 21 is arranged on the third layer, between the secondary crushing section 13 and the packaging module 3, and is used to sort the second particle size koji powder falling from the secondary crushing section 13 and then convey it to the packaging module 3; the control gate valve 22 is located at the lower end of the spiral conveying unit 21, and is used to control the second particle size koji powder inside the spiral conveying unit 21 to fall into the packaging module 3.

[0059] The spiral conveying unit 21 includes a merging screw 211 and a material dividing screw 212 ; the control gate valve 22 may be a pneumatic gate valve 221 .

[0060] Specifically, the converging screw 211 and the dividing screw 212 are both arranged on the third floor. As can be seen from the above, since there are two hammer crushers 131, the lower end of the hammer crusher 131 is fixedly connected with the upper end of the discharge buffer pipe 5 through a flange, therefore, two discharge buffer pipes 5 are also vertically arranged, corresponding to the hammer crusher 131 one by one. The upper end of the converging screw 211 is provided with two inlets, which are respectively fixedly connected with the lower ends of the two discharge buffer pipes 5 through flanges, so the discharge buffer pipe 5 can be arranged through the floor. The lower end of the converging screw 211 is connected with the upper end of the dividing screw 212. When the second particle size koji powder enters the converging screw 211 through the discharge buffer pipe 5 under the action of gravity, it can be temporarily stored for a short time, and then enters the dividing screw 212 to realize the dividing and conveying operation of the second particle size koji powder. Among them, the merging screw 211 and the dividing screw 212 are both screw conveyors, which are continuous conveying equipment without disturbing traction components. They use rotating spiral blades to push the conveyed materials along the surface of a fixed casing to carry out the conveying work, and the screw conveyor is provided with an anti-blocking mechanism. If a blockage occurs, an alarm can be sounded and the front-end material supply can be suspended.

[0061] It should also be noted that a discharge air lock valve is also provided between the converging screw 211 and the dividing screw 212. The discharge air lock valve is generally opened intermittently, and the second particle size koji powder can be temporarily stored in the converging screw 211 for a short period of time, and after reaching a certain amount, it enters the dividing screw 212 through the discharge air lock valve. When the discharge air lock valve is working, the material falls from the converging screw 211 into the dividing screw 212 by its own weight.

[0062] The control gate valve 22 is located at the lower end of the material distribution screw 212, and is used to control the second particle size koji powder inside the material distribution screw 212 to fall into the packaging module 3, that is, after the second particle size koji powder reaches a certain amount, it can enter the packaging module 3 by controlling the pneumatic gate valve 221. Among them, when the pneumatic gate valve 221 is working, based on the control instruction, the compressed air enters the cylinder through the solenoid valve, etc., drives the cylinder to operate, and then drives the gate assembly to make a linear motion, so as to achieve the purpose of opening and closing the valve plate.

[0063] The arrangement of the above-mentioned conveying module 2 mainly relies on gravity conveying during the material distribution and transportation of the koji powder of the second particle size, and the particle size of the koji powder is relatively complete. This solves the problem in the prior art of relying on air conveying pipe networks and cyclone separators for transportation, which causes some particles to collide with each other and the particle size becomes smaller and smaller. At the same time, it can also solve the problem of relatively large noise caused by the friction of materials in the pipeline.

[0064] In one embodiment, continue to refer to Figure 1 , Figure 2 The packaging module 3 includes a koji powder storage section 31 and a quantitative packaging section 33; the koji powder storage section 31 is arranged between the second floor and the first floor through the floor, and is connected with the spiral conveying unit 21, and is used for storing and monitoring the koji powder of the second particle size falling from the spiral conveying unit 21; the quantitative packaging section 33 is arranged on the first floor, and is connected with the koji powder storage section 31, and is used for packaging the koji powder of the second particle size falling from the koji powder storage section 31 when the koji powder of the second particle size falls from the koji powder storage section 31 reaches the rated weight for easy transportation.

[0065] The koji powder storage section 31 may be a koji powder packaging bin 311 ; the quantitative packaging section 33 may be a quantitative packaging scale 331 , and two koji powder packaging bins 311 and two quantitative packaging scales 331 are provided and correspond to each other.

[0066] Specifically, the koji powder packaging bin 311 is arranged between the first and second floors through the floor, and the lower end of the material distribution screw 212 is provided with two outlets, and the pneumatic gate valve 221 is also provided with two, which are located at the lower end of the two outlets, and the upper ends of the two koji powder packaging bins 311 are respectively connected to the pneumatic gate valve 221 by flanges. Generally, after the transfer vehicle arrives, the pneumatic gate valve 221 is opened. Since the lower end of the material distribution screw 212 is provided with two outlets, the koji powder of the second particle size can enter the corresponding koji powder packaging bin 311 from the outlet of the material distribution screw 212 for temporary storage and then fall into the quantitative packaging scale 331. Here, since the koji powder packaging bin 311 itself only has the function of storing materials and cannot monitor the height and weight of the materials, it is possible to install a rotary level meter at the upper and lower parts of the koji powder packaging bin 311 according to actual needs, or place a weighing sensor at the load-bearing position of the koji powder packaging bin 311 to monitor the position and weight of the materials in the koji powder packaging bin 311. Among them, the rotary resistance level meter adopts the principle of electromechanical potential control and measures the material level by contact. When there is no material in the blade part of the koji powder packaging bin 311, the level meter is powered on, the indicator light is on, and the blade rotates counterclockwise; when there is material in the blade part of the koji powder packaging bin 311, the rotation of the blade is blocked and the level meter is powered off. The weighing sensor changes with the weight it bears, and can convert the weight signal or pressure signal into an electrical signal to realize the weighing display of the material. That is, the koji powder packaging bin 311 not only has a temporary storage function, but also can monitor the high and low material levels and monitor and display the weight.

[0067] The quantitative packaging scale 331 is set up in the underground of the first floor and is connected to the two koji powder packaging bins 311 respectively, so as to facilitate the transportation of the koji powder after packaging. The quantitative packaging scale 331 can pack the koji powder of the second particle size falling from the koji powder storage part 31 into bags when the koji powder of the second particle size falls from the koji powder storage part 31 to facilitate the transportation by the subsequent transfer vehicle. Among them, when the quantitative packaging scale 331 is working, the upper material falls in by its own weight, and the bottom discharge valve of the quantitative packaging scale 331 is closed. When the material reaches the rated weight, the top feed end valve of the quantitative packaging scale 331 is closed, and the bottom discharge valve is opened, and the material is released to realize the packaging.

[0068] In one achievable manner, referring to Figure 1 , Figure 2 As shown, the packaging module 3 also includes a rotor quantitative unit 32; the rotor quantitative unit 32 is arranged on the first layer, located between the koji powder storage unit 31 and the quantitative packaging unit 33, and is used to control the second particle size koji powder falling from the koji powder storage unit 31 to fall continuously, evenly and quantitatively into the quantitative packaging unit 33.

[0069] The rotor dosing unit 32 may be a rotor doser 321 .

[0070] Specifically, the packaging module 3 also includes a rotor doser 321, which is arranged on the first floor. The upper end of the rotor doser 321 is fixedly connected to the lower end of the koji powder packaging bin 311 through a flange, and the lower end of the rotor doser 321 is fixedly connected to the upper end of the quantitative packaging scale 331 through a flange. Here, the rotor doser 321 is also provided because the rotor doser 321 can continuously, evenly and quantitatively transport the koji powder of the second particle size that falls into it to the quantitative packaging section 33, that is, by using the rotation of its own valve core, the logistics is continuously, evenly and quantitatively discharged. If there is no rotor dosing section 32, the incoming material may be very unstable due to the action of gravity, sometimes a lot of incoming material, sometimes very little incoming material.

[0071] The arrangement of the above-mentioned packaging module 3 can not only realize the packaging and quantification of the second particle size koji powder, but also is provided with a rotor doser 321 to enhance the stability of the incoming materials for the convenience of packaging and weighing.

[0072] In one embodiment, continue to refer to Figure 1 , Figure 2 As shown, the dust removal module 4 includes a dust removal part 41 and a ventilation part 42; the dust removal part 41 is arranged between the third floor and the fourth floor through the floor, and is connected with the spiral conveying unit 21, and is used for dust removal and recovery operations on the second particle size koji powder falling into the spiral conveying unit 21; the ventilation part 42 is arranged on the fourth floor, and is connected with the dust removal part 41, and is used to accelerate the air circulation inside the spiral conveying unit 21 and the dust removal part 41, and cool down the second particle size koji powder falling into the spiral conveying unit 21 and the dust removal part 41.

[0073] The dust removal part 41 may be a bag dust collector 411 , and the ventilation part 42 may be a centrifugal fan 421 .

[0074] Specifically, the system is also provided with a dust removal module 4, which includes a bag dust collector 411 and a centrifugal fan 421. The bag dust collector 411 is arranged between the third layer and the fourth layer and is connected to the converging spiral 211, and can perform dust removal and recovery operations on the second particle size koji powder entering the converging spiral 211. Here, the lower end of the bag dust collector 411 is also provided with a discharge air lock valve, and the discharge air lock valve is generally opened intermittently, that is, the dust generated by the second particle size koji powder enters the bag dust collector 411, and a certain amount can be stored in its ash hopper, and then fall into the converging spiral 211 after reaching a certain amount, so that part of it is used and transported downward together with the second particle size koji powder in the converging spiral 211, and part of it enters the bag dust collector 411 again, and so on and so forth, so as to realize the recycling of the second particle size koji powder.

[0075] The working principle of the bag filter 411 is as follows: the dust-laden gas enters from the air inlet of the downflow air box of the bag filter 411, and is diverted to the dust collecting hopper through the shielding plate. At this time, the air flow speed slows down. Under the action of inertia and gravity, the coarse dust particles in the gas fall directly into the dust collecting hopper, and the fine dust adheres to the surface of the filter bag. The purified gas enters the top cleaning chamber and can be sucked out through the air outlet of the cleaning chamber and discharged into the atmosphere. In addition, due to the provision of the downflow air box and the shielding plate, the high-speed dust-laden airflow is avoided from directly scouring the filter bag, thereby extending the service life of the filter bag. At the same time, the air flow entering the filter chamber is more uniform and stable, so that the working conditions of each filter bag are basically synchronized, thereby increasing the utilization rate of the filter bag. In addition, the pulse valve of the bag filter 411 is sprayed and cleaned online, and the spraying time is controlled by the program controller and can be adjusted, thereby improving the dust removal efficiency of the whole machine.

[0076] The centrifugal fan 421 is arranged on the fourth floor and is connected to the bag dust collector 411 through the ventilation duct. It can accelerate the air circulation inside the spiral conveying unit 21 and the dust removal part 41, and cool the second particle size koji powder falling into the spiral conveying unit 21 and the dust removal part 41. A manual butterfly valve is provided on the ventilation duct to adjust the air volume of the centrifugal fan 421 and enhance the stability of air circulation.

[0077] In one achievable manner, referring to Figure 2 As shown, the ventilation part 42 is provided with a muffler 4211 ; the muffler 4211 is used to reduce the noise generated by the ventilation part 42 .

[0078] Here, a muffler 4211 is connected to the upper end of the centrifugal fan 421 to reduce the noise generated by the ventilation part 42.

[0079] The setting of the above-mentioned bag dust collector 411 is mainly used to remove dust from the environment. While removing dust from the second particle size koji powder, it can also be recycled again; the setting of the centrifugal fan 421 can achieve the cooling operation of the second particle size koji powder by accelerating the gas flow to ensure the quality of the koji powder; the setting of the muffler 4211 can greatly reduce the production noise and provide a quiet environment for the staff.

[0080] In one embodiment, continue to refer to Figure 1 , Figure 2 As shown, the dust removal module 4 also includes a second dust removal part 43 and a pipe connecting part 44; the second dust removal part 43 is arranged on the first floor, located on one side of the quantitative packaging part 33, and is used to perform dust removal operations on the packaging area of ​​the quantitative packaging part 33; the pipe connecting part 44 is arranged between the first floor and the third floor through the floor, one end of which is connected to the second dust removal part 43 and the other end is connected to the spiral conveying unit 21, and is used to transport the koji dust collected by the second dust removal part 43 to the spiral conveying unit 21 for re-dust removal and recovery.

[0081] The second dust removal part 43 may be a packaged dust collection hood 431 ; and the duct connecting part 44 may be a dust removal duct 441 .

[0082] Specifically, the packing dust hood 431 is arranged in the first-layer packing area, located on one side of the quantitative packing scale 331, and is used to perform dust removal operations on the packing area at the quantitative packing scale 331 to achieve environmental dust removal in the packing area.

[0083] The dust removal duct 441 is arranged between the first and third floors and passes through the floors. The lower end of the dust removal duct 441 is connected to the upper end of the packaged dust hood 431 through a flange, and the upper end of the dust removal duct 441 is connected to the merging spiral 211, so that the second particle size koji dust collected by the packaged dust hood 431 can be transported to the merging spiral 211. However, since the merging spiral 211 is connected to the bag dust collector 411, it can be seen from the above that the second particle size koji dust can be removed again to achieve the effect of repeated recycling.

[0084] The setting of the above-mentioned packaging dust hood 431 can realize dust removal in the packaging area environment, thereby reducing dust concentration, ensuring the health of workers and a clean environment; the setting of the dust removal duct 441 can remove dust again to achieve the effect of recycling koji powder dust and improving the quality of koji powder.

[0085] It needs to be emphasized again that the above-mentioned components are all connected by flange interfaces, with occasional diameter changes in the middle. The larger distances are connected by pipes, but the interfaces are also flange connections.

[0086] The overall implementation principle of this embodiment is: the claw crusher 111 performs primary crushing on the koji blocks to obtain koji powder of a first particle size, and the koji powder of the first particle size falls into the classifier and iron remover 121. After the classifier and iron remover 121 classify and remove iron from the koji powder of the first particle size, the koji powder of the first particle size falls into the hammer crusher 131. The hammer crusher 131 performs secondary crushing on the koji powder of the first particle size to obtain koji powder of a second particle size; the koji powder of the second particle size falls into the merging screw 211 through the discharge buffer pipe 5 for transportation, and because the merging screw 211 is connected to the bag dust collector 411, and the bag dust collector 411 is connected to the centrifugal fan 421, therefore, while realizing the transportation of the koji powder of the second particle size, it can also be realized Through repeated recycling and cooling operations, the koji powder of the second particle size falls into the dividing screw 212 after being cooled, and the koji powder of the second particle size is continued to be transported. Since the pneumatic gate valve 221 is provided at the lower end of the dividing screw 212, the pneumatic gate valve 221 is opened, and the koji powder of the second particle size can fall into the koji powder packaging bin 311; the koji powder packaging bin 311 temporarily stores and monitors the koji powder of the second particle size; the koji powder of the second particle size is controlled to fall into the rotor doser 321, and the rotor doser 321 controls the koji powder of the second particle size to fall into the quantitative packaging scale 331 continuously, evenly and quantitatively. When the koji powder of the second particle size in the quantitative packaging scale 331 reaches the rated weight, the koji powder of the second particle size is packed in bags for the convenience of transportation by the subsequent transfer vehicle. This application can realize the crushing and transportation of curved blocks through the coordination of three modules: crushing module, conveying module and packaging module. There is no need to excavate foundation pit, which facilitates construction, saves construction time and investment costs. Moreover, since the entire crushing and conveying system is a closed production system, there is no dust spillage, which can ensure a good working environment.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
