[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] The embodiment of the present invention provides a finished product silo for dry-mixed mortar, thereby solving the problem that the existing dry-mixed mortar finished product silo has a single function and cannot reduce the dust spillage of the dry-mixed mortar during the unloading and bagging processes, thereby increasing the loss of dry-mixed mortar and the probability of pollution to surrounding equipment or the environment.

[0035] like Figures 1 to 4As shown, in order to achieve the amount of dust overflow during the bagging process of dry-mixed mortar and facilitate the monitoring of the state of dusty mortar during the bagging process, a preferred embodiment of the present invention proposes a finished product silo for dry-mixed mortar, including a storage tank 1, a support structure 2 is provided on the outside of the storage tank 1, the storage tank 1 is in a suspended state away from the ground, a dust reduction bin 3 is fixedly installed at the lower part of the support structure 2, a discharge port is provided at the bottom of the storage tank 1, and a quantitative bin 4 is movably installed at the discharge port position of the storage tank 1, the storage tank 1, the quantitative bin 4 and the dust reduction bin 3 are connected in sequence, and a group of opening and closing valves 41 are respectively provided at the upper and lower connecting ports of the quantitative bin 4, in addition, it also includes a sampling tube 5, the quantitative bin 4 is a gyro-shaped structure, and a plurality of sampling tubes 5 are respectively arranged at different circumferential diameter positions on the upper part of the quantitative bin 4, the sampling tube 5 is connected to the internal cavity of the quantitative bin 4, and a temperature sensor 51 and a humidity sensor 52 are respectively installed in the plurality of sampling tubes 5.

[0036] During operation, the prepared mixed dry-mixed mortar is uniformly stored in the storage tank 1, and the storage tank 1 is used to seal and moisture-proof the dry-mixed mortar. When not bagged, the opening and closing valves 41 at the upper and lower ports of the quantitative bin 4 are in a closed state. A temperature sensor 51 and a humidity sensor 52 are installed in the sampling tube 5. While monitoring the environmental factors inside the quantitative bin 4, the sampling tube 5 is blocked. Subsequently, when bagging is required, the opening and closing valve 41 on the upper part of the quantitative bin 4 is opened, and the dry-mixed mortar in the storage tank 1 falls into the quantitative bin 4 under the action of gravity and fills the inner cavity thereof. The volume of the internal cavity of the quantitative bin 4 can be dynamically adjusted according to the rated capacity of the packaging bag 8 during a single bagging operation.

[0037] After the rated capacity of dry-mixed mortar is filled in the quantitative bin 4, the dry-mixed mortar in the storage tank 1 stops falling. At this time, the opening and closing valve 41 on the upper part of the quantitative bin 4 is closed, and the quantitative bin 4 is in a closed state again. At the same time, the temperature sensor 51 and the humidity sensor 52 can detect the state of the dry-mixed mortar in the quantitative bin 4, and judge whether the dry-mixed mortar is affected by moisture in the air and deliquesces or oxidizes during storage according to the changes in temperature and humidity values. When vertical abnormality is detected, the temperature sensor 51 or the humidity sensor 52 is pulled out, and the existing sampling tube or sampling spoon is used to insert the sampling tube 5, thereby realizing the extraction operation of the dry-mixed mortar inside the quantitative bin 4, and the sampled dry-mixed mortar is subjected to secondary inspection by visual inspection or professional equipment. This process uses the bag change stop interval of the bagging process to realize real-time monitoring of the state of the dry-mixed mortar. While judging the storage state of the dry-mixed mortar at each layer in the storage tank 1, it is also beneficial to improve the control degree of the quality of each batch of bagged dry-mixed mortar, and improves the delivery quality of the dry-mixed mortar without affecting the bagging efficiency.

[0038] Furthermore, in order to achieve the quantitative requirements during bagging and reduce the residual adhesion of dry-mixed mortar, such as Figure 4 , Figure 6 and Figure 7 As shown, the middle part of the quantitative bin 4 is evenly installed with a roller 42 by means of rotational cooperation, and the roller 42 is parallel to the axis of the quantitative bin 4. The upper part of the dust reduction bin 3 is rotatably installed with an end cover 6, and the middle part of the end cover 6 is rollingly cooperated with the roller 42, and the middle part of the end cover 6 is circumferentially provided with a plurality of concave cylindrical grooves that fit with the outer arc surface of the roller 42, an annular airflow channel 31 is arranged at the edge position of the dust reduction bin 3, the edge position of the end cover 6 is located in the airflow channel 31, and the edge position of the end cover 6 is circumferentially provided with blades 61.

[0039] During operation, after the rated capacity of dry-mixed mortar is stored in the quantitative bin 4, air flow is intermittently introduced into the annular air flow channel 31 through the existing air pump. Subsequently, under the push of the air flow, the end cover 6 begins to rotate, and during the rotation, it forms contact with the roller 42 and produces relative rolling. At this time, the cylindrical groove opened in the middle of the end cover 6 transfers between the rollers 42 at different positions and forms intermittent contact, and then collides relative to each other, thereby generating vibration, and the vibration is transmitted to the quantitative bin 4 through the roller 42. Through the intermittent vibration effect, the dry-mixed mortar is prevented from being squeezed and adhered after flowing into the internal cavity of the quantitative bin 4, thereby improving its looseness. While being beneficial to temperature and humidity monitoring, it is also beneficial to the discharge flow smoothness in the subsequent bagging process.

[0040] Furthermore, in order to realize the dynamic control of the bagging capacity of the dry-mixed mortar, while adjusting the solvent in the cavity of the quantitative bin 4, Figure 3 and Figure 4 As shown, a tensile meter 43 for measuring the quality of the content of the quantitative bin 4 is provided at the connection portion between the quantitative bin 4 and the port of the storage tank 1 .

[0041] When the bagging volume of the dry-mixed mortar to be packed changes briefly, the internal volume of the quantitative bin 4 remains unchanged. At this time, as the dry-mixed mortar in the storage tank 1 flows into the quantitative bin 4, the reading of the tension meter 43 gradually increases. The inflow weight of the dry-mixed mortar in the quantitative bin 4 is calculated by the tension. When the predetermined weight is reached, the opening and closing valve 41 is closed, thereby realizing dynamic control of the bagging quality of the dry-mixed mortar under different bagging conditions, and having wide applicability.

[0042] Furthermore, in order to achieve dust isolation and dust reduction during the bagging process and avoid dust spillage causing pollution to the external environment and surrounding equipment, such as Figures 3 to 5 ,as well as Figure 7 , Fig. 9 and Fig.10As shown, an inlet and outlet are provided in the middle of one side of the dust reduction bin 3, a carrying frame 7 is fixedly installed at the bottom of the inlet and outlet, and a conveying roller 71 is evenly installed in the carrying frame 7 by means of rotational cooperation, a packaging bag 8 is placed on the upper part of the conveying roller 71, the bag opening of the packaging bag 8 faces upward and the packaging bag 8 is located below the quantitative bin 4, a mouth opening clamp 44 is slidably installed at the lower port position of the quantitative bin 4, an electric push rod is fixedly installed at the lower part of the quantitative bin 4, the telescopic end of the electric push rod is fixedly connected to the mouth opening clamp 44, the mouth opening clamp 44 is in contact with the bag opening of the packaging bag 8, and the transportation A long groove 72 is opened in the middle of the carrier frame 7, and a slider 73 is slidably installed in the long groove 72. A compression spring 74 is connected between the slider 73 and the carrier frame 7. A sleeve rod 75 is symmetrically installed on the upper part of the slider 73 and the edge of the carrier frame 7, and a dust-proof curtain 76 is sleeved between the two sleeve rods 75. Two dust-proof curtains 76 are provided, and the two dust-proof curtains 76 are respectively located on both sides of the inlet and outlet of the dust reduction bin 3. The dust-proof curtain 76 is a flexible structure. The dust-proof curtain 76 is located on the inner side of the dust reduction bin 3 and counterweights 77 are evenly arranged on the dust-proof curtain 76.

[0043] When the bag 8 is in the closed position, the slider 73 is pushed downward by the elastic force of the compression spring 74, and the dust-proof curtains 76 on both sides are in the expanded state, and the inner space of the dust-proof bin 3 is relatively closed. Subsequently, the existing manipulator is used to clamp the packaging bag 8 and push it to the inner side of the dust-proof bin 3. During this process, the slider 73 is squeezed and separated to both sides, and the dust-proof curtains 76 are contracted synchronously. The inlet and outlet positions of the front of the dust-proof bin 3 are opened, and the packaging bag 8 enters. When the packaging bag 8 enters and reaches the predetermined position, the opening clamp 44 is pushed downward by the electric push rod, thereby opening and fixing the bag mouth of the packaging bag 8. Subsequently, the external manipulator moves out, and the slider 73 moves to the center again after losing the squeezing effect. Subsequently, the opening and closing valve 41 at the bottom of the quantitative bin 4 is opened, and the bagging operation of the dry mixed mortar is carried out. During the bagging process, the overflowing dust is located on the inner side of the dust-proof bin 3 and settles autonomously, thereby reducing the pollution to the external environment and equipment.

[0044] Furthermore, in order to realize the dust removal operation on the outer wall of the packaging bag 8 and reduce the pollution and damage to personnel or equipment during the subsequent transfer and handling process, Figure 4 , Figure 5 ,as well as Figures 8 to 10As shown, a grooming shaft 731 is rotatably installed on the upper part of the slider 73, and grooming bristles are evenly arranged on the side walls of the shaft body of the grooming shaft 731. A motor is fixedly installed on the lower part of the slider 73, and the motor output shaft is fixedly connected to the grooming shaft 731. During the movement of the packaging bag 8, its outer side wall is in rolling contact with the grooming shaft 731. A hollow suspension rod 9 is fixedly installed on the lower part of the end cover 6, and a dust suction plate 91 is slidably installed in the middle part of the suspension rod 9. A swing spring 92 is connected between the dust suction plate 91 and the suspension rod 9. A dust suction pipe 93 is arranged on the side of the dust suction plate 91 facing the packaging bag 8. The dust suction pipe 93 is connected to the packaging bag 8. The internal cavity of the suspension rod 9 is connected, and a dust collector is fixedly installed at the lower part of the supporting structure 2, and the dust collector is connected to the interior of the suspension rod 9 through an air pipe, and an air collecting plate 94 made of flexible material is installed between the suspension rod 9 and the dust collecting plate 91. The air collecting plate 94 can be made of metal sheet or plastic sheet. The air collecting plates 94 are respectively located on both sides of the dust collecting plate 91, and an angle of 30 to 75 degrees is formed between the air collecting plates 94 and the dust collecting plates 91. A convex ball 95 is fixedly provided at the lower end of the dust collecting plate 91, and a convex ring 732 in contact with the convex ball 95 is fixedly installed at the lower end of the grooming shaft 731.

[0045] During operation, when the rated capacity of dry-mixed mortar is bagged, the dust collector is started to work, and the inner side of the dust reduction bin 3 is exhausted through the dust suction pipe 93. During the exhaust process, the suspended dust is adsorbed and collected. In order to improve the absorption degree and efficiency of suspended particles, the inclined air collecting plate 94 can make the airflow gradually tend to concentrate in the process of flowing toward the dust suction plate 91, thereby increasing its flow rate, increasing the negative pressure, and facilitating the movement of suspended particles in the surrounding space. At the same time, by increasing the flow rate of the airflow, the probability of secondary adhesion of dust during the flow process can also be reduced, which can effectively control the suspended particles in the air. After the dust removal is completed, the clamping effect of the opening clamp 44 on the bag mouth of the packaging bag 8 is released, the conveying roller 71 is started to work, and the packaging bag 8 begins to move to the outside of the dust reduction bin 3. At the same time, the slider 73 is pushed to slide to both sides by an external manipulator. When one side of the packaging bag 8 reaches the position of the cleaning shaft 731, the motor is started to operate, thereby driving the cleaning shaft 731 to rotate. At this time, the cleaning shaft 731 realizes the cleaning of the dust on the surface of the packaging bag 8 during the self-rotation process. By controlling the steering direction of the cleaning shaft 731, the dust is moved to the inside of the dust reduction bin 3, and the adsorption process of the dust suction plate 91 is cooperated to realize the secondary collection and treatment of the dust.

[0046] When the packaging bag 8 is completely moved out of the dust reduction bin 3, it is transported and packaged by an external manipulator or staff, and the slider 73 is reset again under the action of the elastic force of the compression spring 74. At this time, air is introduced into the air flow channel 31 through the air pump, and then the end cover 6 rotates and drives the dust collection plate 91 to rotate through the suspension rod 9. The internal air flow of the dust reduction bin 3 is disturbed by the rotation action, thereby increasing the suspended amount of residual dust inside the dust reduction bin 3, and cooperating with the suction effect of the dust collection plate 91 to achieve the removal of residual dust. When the shaft 731 is in the right position, the brief contact between the convex ball 95 and the convex ring 732 causes the grooming shaft 731 to vibrate, and then the vibration is transmitted to the dust-proof curtain 76 through the slider 73. In combination with the inertial shaking of the counterweight block 77 under the action of vibration, the dust-proof curtain 76 and the grooming brush bristles on the grooming shaft 731 can be shaken off, thereby further improving the cleanliness of the internal cavity of the dust reduction bin 3 and reducing dust residue in the bagging process. While reducing secondary pollution, it realizes the collection operation of dust spilled from the dry-mixed mortar and reduces material loss.
