Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the intelligent automatic feeding system disclosed by the invention comprises a material storage unit 1 for storing ingredients required by concrete. The material storage unit 1 comprises a cement storage module 2, a broken stone storage module 3, a sand storage module 4, a water storage module 5, an additive storage module 6 and a detection module 7.

Referring to fig. 2, as an embodiment of the stock unit 1, a cement storage module 2, a crushed stone storage module 3, a sand storage module 4, a water storage module 5, and an admixture storage module 6 are provided as a cylindrical cone-bottom storage tank. The concrete storage tank comprises five cylindrical storage tanks with conical bottoms, a cement storage module 2, a gravel storage module 3, a sand storage module 4, a water storage module 5 and an additive storage module 6, wherein the five cylindrical storage tanks with conical bottoms are used for storing ingredients required by concrete, and the concrete storage module is specifically used for storing cement, gravel storage module 3 and water, and the additive storage module 6 is used for storing water and additives required by concrete stirring, such as a water reducing agent, an air entraining agent or an accelerator. Five cylindrical awl end storage tanks all are connected with a support 21, and support 21 supports each cylindrical awl end storage tank, and the convenience is arranged the material. The upper end of cylindrical awl end storage tank all is equipped with the inlet pipe 23 that is used for the feeding, and sealing connection has sealed lid 24 on the inlet pipe 23. The lower extreme of five cylindrical cone end storage tanks all is equipped with the discharging pipe 22 that is used for the ejection of compact.

Referring to fig. 3, the detection module 7 is used for detecting the remaining amount of cement in the cement storage module 2, crushed stones in the crushed stone storage module 3, sand in the sand storage module 4, water in the water storage module 5 and the additive in the additive storage module 6. In particular, the detection module 7 comprises a distance detection module 71 and a liquid level detection module 72. The distance detection module 71 is a distance sensor, and the liquid level detection module 72 is a liquid level sensor. Wherein, distance detection module 71 is installed respectively to the inside upper end of cement storage module 2, rubble storage module 3 and husky storage module 4, and distance detection module 71 is arranged in detecting the pile height that corresponds the batching among its self storage module and generates corresponding pile height data. For example, the distance detection module 71 located in the cement storage module 2 detects the stacking height of cement and generates cement stacking height data, and similarly, broken stones correspond to broken stone stacking height data; the sand corresponds to sand pile height data. The bulk height data is the bulk height value of the ingredient.

Referring to fig. 3, liquid level detection modules 72 are respectively installed in the water storage module 5 and the admixture storage module 6, and the liquid level detection modules 72 are used for detecting the liquid level heights of the corresponding ingredients in the storage modules where the liquid level detection modules 72 are located and generating corresponding liquid level height data. Specifically, the liquid level detection module 72 located in the water storage module 5 detects the depth of water and generates water liquid level height data; the liquid level detection module 72 in the additive storage module 6 detects the depth of the additive and generates additive liquid level height data. Liquid level height data is the height value of the liquid.

Referring to fig. 3, the detection module 7 comprises a budget module 73 wirelessly connected to each distance detection module 71 and each liquid level detection module 72. The connection may be a bluetooth connection or a wireless network connection. The budget module 73 can be a PLC control system or a computer, and the budget module 73 is used for acquiring correspondingly generated stacking height data from each distance detection module 71 and correspondingly generated liquid level height data from each liquid level detection module 72. When a certain stacking height data acquired by the budget module 73 is smaller than a stacking height threshold value preset corresponding to the stacking height data, generating a corresponding alarm instruction; when a certain liquid level height data acquired by the budget module 73 is smaller than a preset liquid level height threshold corresponding to the liquid level height data, a corresponding alarm instruction is generated. When the budget module 73 generates an alarm instruction, it proves that the ingredients in the corresponding storage module need to be replenished.

For convenience of understanding, for example, if the cement pile height data received by the budget module 73 is smaller than the preset cement pile height threshold, the budget module 73 generates a cement alarm instruction, and so on. When a cement alarm instruction is generated, the fact that the residual quantity of the cement in the cement storage module 2 is too small is proved, and the cement needs to be supplemented.

Referring to fig. 3, the detection module 7 includes an alarm module 74 wirelessly connected to the budget module 73. The alarm module 74 is configured to receive the alarm instruction transmitted by the budget module 73, and when the alarm module 74 receives the alarm instruction, perform an alarm. As an embodiment of the alarm module 74, the alarm module 74 is configured as a plurality of audible and visual alarms installed in a worker's work room or a control room of the feeding system. Each audible and visual alarm corresponds to a storage module, namely in the embodiment, 5 audible and visual alarms are arranged, and workers judge the types of ingredients needing to be supplemented according to the positions of the audible and visual alarms. Further, as another embodiment of the alarm module 74, the alarm module 74 is provided as an alarm program provided in a computer. When the alarm module 74 receives the alarm instruction, it pops up the alarm information on the display screen of the computer according to the alarm instruction. The worker knows the type of the ingredients to be supplemented according to the alarm information.

Referring to fig. 3, the detecting module 7 includes an estimating module 75 connected to the budgeting module 73, the estimating module 75 is a single chip, and the estimating module 75 is configured to obtain the stacking height data and the liquid level height data from the budgeting module 73. The estimation module 75 is further configured to calculate the amount of change in the height of the ingredient in the corresponding storage module during the day based on each pile height data or each liquid level height data and generate corresponding height change data. For example, the estimation module 75 obtains the cement pile height data from the budget module 73 at 6 o 'clock in the morning, and by the next day at 6 o' clock in the morning, the estimation module 75 obtains the cement pile height data from the budget module 73 again. The estimation module 75 then subtracts the cement stacking height data obtained on the first day from the cement stacking height data obtained on the second day to obtain the usage amount of cement in one day, i.e., height change data.

Referring to FIG. 3, the estimation module 75 transmits the altitude change data to the budgeting module 73, and the budgeting module 73 averages the altitude change data for at least the last two days for each altitude change data. When a certain stacking height data acquired by the budget module 73 is smaller than a corresponding preset stacking height threshold, the average value of the height change data corresponding to the stacking height data is divided by the stacking height data to obtain the expected usage days of the ingredient, and the day data is generated according to the calculated expected usage days of the ingredient. The data of days represents the number of days a certain ingredient is expected to be used, and after the number of days, the ingredient is exhausted.

For convenience of understanding, for example, the height variation of the cement in the cement storage module 2 of the last two days is 0.4 meter and 0.6 meter, respectively, and the height variation data of the cement of the last two days is 0.4 and 0.6, respectively. The budget module 73 calculates the average of the height variation data for the last two days, and then calculates the average of the height variation data for cement to be 0.5 using (0.4 + 0.6)/2 = 0.5. When the cement pile height data is less than the cement pile height threshold, the budget module 73 calculates the expected number of days of use of cement by dividing the cement pile height data by 0.5.

Referring to fig. 3, the budget module 73 is configured to generate a corresponding alarm instruction when the number of days data is less than a preset number of days threshold corresponding to the number of days data, and transmit the alarm instruction to the alarm module 74, so that the alarm module 74 gives an alarm. Due to the estimation module 75 and the setting of the day threshold, there are two situations for the budgeting module 73 to generate alarm instructions. One condition is that the stacking height data or the liquid level height data is less than a corresponding preset stacking height threshold or a liquid level height threshold; in another case, the number of days is less than a preset number of days threshold corresponding to the number of days.

Due to the above two situations, it is easy to happen that when the alarm module 74 gives an alarm, the height of the ingredient is smaller than the corresponding height threshold, but the number of days of the ingredient is not smaller than the corresponding set number of days threshold through the calculation of the budget module 73, which proves that the ingredient can be used for a certain number of days. If the ingredients are added to the storage module corresponding to the ingredients, the ingredients are easily extruded in the corresponding storage module for a long time, so that quality degradation occurs, and the final quality degradation of concrete is caused. In order to solve the above phenomenon, the worker can adaptively change the stacking height threshold value and the liquid level height threshold value according to actual conditions, i.e. the values of the stacking height threshold value and the liquid level height threshold value are reduced. In this way, even if the stacking height or the liquid level height of a certain ingredient is smaller than the corresponding height threshold value newly set, the alarm module 74 gives an alarm, and a worker fills the ingredient, so that the ingredient is not easy to be extruded for a long time. Because the amount of the ingredient remaining when the alarm module 74 alarms is low, the amount of the ingredient remaining before filling can be used up as soon as the concrete production in the next few days is greater than the concrete production in the previous few days.

Referring to fig. 3, the detection module 7 includes an anti-caking module 76 for preventing caking of cement in the cement storage module 2 and preventing deterioration of concrete quality. The anti-caking module 76 comprises a caking control module 763, a ventilation module 764, a stirring module 761 for stirring cement in the cement storage module 2, and a humidity detection module 762 for detecting air humidity in the cement storage module 2 and generating humidity data. Humidity detection module 762 is set as the humidity detection sensor, and caking control module 763 is connected with stirring module 761 and humidity detection module 762. The agglomeration control module 763 may be a PLC control system or a computer for controlling the operation state of the stirring module 761 and acquiring humidity data. When the agglomeration control module 763 looks up a preset humidity threshold from the humidity data obtained from the humidity detection module 762, a ventilation instruction is generated.

Referring to fig. 3, ventilation module 764 is wirelessly coupled to agglomeration control module 763 and is configured to receive ventilation instructions. When the ventilation module 764 receives the ventilation instruction, dry gas is delivered into the cement storage module 2 while humid gas in the cement storage module 2 is exhausted.

As an embodiment of the stirring module 761, referring to fig. 4, the stirring module 761 includes a stirring rod 7611 vertically disposed inside the cement storage module 2, and a plurality of stirring blades 7612 are disposed on the stirring rod 7611. The stirring module 761 also includes a rotating motor 7613 located on the upper surface of the cement storage module 2 and having an output end extending into the cement storage module 2, the output end of the rotating motor 7613 is connected with the upper end of the stirring rod 7611, and the output end of the rotating motor 7613 is rotatably connected with the cement storage module 2.

Referring to fig. 4, the ventilation module 764 includes an air inlet pipe 7641 connected to the inside of the cement storage module 2, and an air inlet fan 7642 is connected to an end of the air inlet pipe 7641 away from the cement storage module 2. Referring to fig. 3, the air inlet fan 7642 is connected to the agglomeration control module 763, and when the humidity data received by the agglomeration control module 763 exceeds a preset humidity threshold, the agglomeration control module 763 controls the air inlet fan 7642 to start. The air inlet machine 7642 delivers dry air to the inside of the cement storage module 2 through an air inlet pipe 7641. In particular, the drying air is generated and supplied by a drying air generator.

The implementation principle of the embodiment is as follows: when concrete needs to be produced, the quantity regulating module 831 controls the discharging module 81 to discharge the broken stones according to the preset broken stone discharging quantity. Due to the volume of the crushed stones, the actual discharge amount of the crushed stones is easily larger than the preset discharge amount of the crushed stones. At this moment, the quantity adjusting module 831 can calculate the quantity of other ingredients needing to be discharged according to the actual discharge quantity of the crushed stones and the preset ingredient ratio, so that the ratio between the actual discharge quantities of all ingredients is more fit with the preset ingredient ratio, and the accuracy of the concrete is improved.
