Description

Technical Field

[0001] This utility model relates to the field of wind and sand prevention technology, and in particular to a weighing sand flux measurement device. Background Technology

[0002] The harm that wind and sand movement causes to the human living environment is called wind and sand disaster. Essentially, it refers to the damage and destruction caused to farmland, buildings, and transportation by the erosion, transportation, and deposition of sand particles under the action of wind. Wind and sand disasters exacerbate desertification, which in turn destroys the ecological environment upon which humans depend for survival, leading to a rapid loss of large amounts of usable land resources, affecting various industrial and agricultural production activities, and posing a significant threat to human life and property.

[0003] The existing Chinese patent with authorization announcement number CN220729611U discloses a wind-driven self-rotating weighing sand flux collection system, which relates to the field of wind and sand collection technology. The wind-driven self-rotating weighing sand flux collection system includes a sand inlet mechanism, a sand collection mechanism, and a guiding component. The sand inlet mechanism includes a sand inlet cylinder and a filter sand drop pipe. The sand inlet cylinder has an air inlet and an airflow channel connected to the air inlet. The airflow channel is arranged horizontally, and a filter screen is installed at the end of the sand inlet cylinder opposite to the air inlet. The filter sand drop pipe is connected to the airflow channel and is arranged vertically. The sand collection mechanism includes a conveying pipe, an anti-slip sand box, and a weighing component. One end of the conveying pipe is connected to the filter sand drop pipe, and the other end is connected to the opening of the anti-slip sand box. The conveying pipe is rotatably connected to the filter sand drop pipe through a rotating mechanism. The weighing component is located inside the anti-slip sand box. The guiding component is fixed to the sand inlet cylinder and located above the sand inlet cylinder. The guiding component can rotate under the action of wind force so that the air inlet faces the direction of the wind and sand. The air inlet can change with the wind direction, and the sand collection volume is less affected by the wind direction.

[0004] The shortcomings of the above-mentioned existing technical solutions are as follows: the weighing component is located inside the anti-sand box, and the collected sand enters the anti-sand box through the sand inlet cylinder, the sand outlet cylinder and the conveying pipe. After long-term use, a large amount of sand will accumulate inside the anti-sand box. This sand is prone to accumulating and caking inside the box, which not only increases the load on the weighing component, but also requires the staff to frequently open the box for cleaning, increasing maintenance costs and operational difficulty.

[0016] The beneficial effects of this utility model are: 1. In operation, when excessive sand accumulates in the sand collection trough of the weighing box, the tilting motor starts, driving the tilting shaft to rotate. This, in turn, through the cooperation of the connecting shaft and bearing two, causes the inclined plate to tilt downwards, opening the sand delivery port. Subsequently, the motor drives the threaded rod to rotate. Since one end of the moving frame is threadedly connected to the threaded rod and the other end is slidably connected to the sliding rod, the rotation of the threaded rod causes the moving frame to move along the sliding rod. The moving frame, through the connecting rod, drives the push plate to slide within the sand collection trough, pushing the sand out of the sand delivery port and discharging it outside the box. After the sand is discharged, the motor reverses, resetting the push plate. Simultaneously, the tilting motor causes the inclined plate to tilt upwards, bringing the straight plate into contact with the edge of the sand delivery port of the weighing box, closing the sand delivery port for the next sand collection and weighing operation. This structural design automatically cleans the accumulated sand within the weighing mechanism, preventing sand from accumulating and increasing the load on the weighing components, reducing maintenance operations, and lowering maintenance costs and operational difficulty. 2. A side plate is fixedly connected to the side end face of the straight plate of this utility model. The side plate is set on the outside of the box and at the connection between the opening and the straight plate. When the straight plate is attached to the edge of the sand feeding port of the weighing box and the sand feeding port is closed, the side plate can further block the opening and prevent impurities or airflow in the external environment from entering the box through the opening and affecting the measurement accuracy.

[0022] Reference Figures 1 to 5This utility model provides a weighing-type sand flux measurement device, comprising: a sand inlet cylinder 1, a weighing mechanism 10, a baffle mechanism 11, and a pusher mechanism 12. The lower end of the sand inlet cylinder 1 is connected to a lower sand cylinder 3. A protective cover 4 is provided at the lower end of the lower sand cylinder 3. A conveying pipe 6, connected to the lower sand cylinder 3, is provided at the lower end of the protective cover 4. A housing 7 is provided at the lower end of the conveying pipe 6. A weighing sensor 9 is installed inside the housing 7. An opening 8 is provided on the side of the housing 7. The weighing mechanism 10 includes a weighing housing 101, which is mounted on the weighing sensor 9. A sand collection groove 102 is provided on the upper surface of the weighing housing 101. The sand collection groove 102 penetrates the side surface of the weighing housing 101 to form a sand delivery port. Fixed fasteners are provided on both sides of the sand delivery port and are fixedly connected to the weighing housing 101. The fixed plate 103 and the baffle mechanism 11 include an inclined plate 111, on which a straight plate 112 is fixedly connected. The inclined plate 111 is rotatably connected to the fixed plate 103. The push plate mechanism 12 includes a first mounting frame 121 and a second mounting frame 122, both of which are fixedly connected to the weighing box 101. A threaded rod 123 is rotatably connected to the first mounting frame 121. A motor 125 for driving the threaded rod 123 to rotate is provided on the first mounting frame 121. A sliding rod 124 is fixedly connected to the second mounting frame 122. A movable frame 126 is connected to both the threaded rod 123 and the sliding rod 124. A connecting rod 127 is fixedly connected to the movable frame 126. A push plate 128 is fixedly connected to the connecting rod 127.

[0023] One end of the movable frame 126 is sleeved and threadedly connected to the threaded rod 123, and the other end of the movable frame 126 is sleeved and slidably connected to the slide rod 124. Both sides of the inclined plate 111 are fixedly connected to the connecting shaft 113. A flipping motor is provided on the fixed plate 103, and a flipping shaft is provided on the drive end of the flipping motor. There are two fixed plates 103, and a bearing 104 is embedded through both fixed plates 103. The outer ring of the bearing 104 is fixedly connected to the fixed plate 103, and the connecting shaft 113 is sleeved and fixedly connected to the inner ring of the bearing 104. During operation, when too much sand accumulates in the sand collection trough 102 of the weighing box 101, the flipping motor starts, drives the flipping shaft to rotate, and then through the cooperation of the connecting shaft 113 and the bearing 104, the inclined plate 111 flips downward and opens the sand feeding port. Subsequently, motor 125 drives threaded rod 123 to rotate. Since one end of moving frame 126 is threadedly connected to threaded rod 123 and the other end is slidably connected to slide rod 124, the rotation of threaded rod 123 causes moving frame 126 to move along slide rod 124. Moving frame 126 drives push plate 128 to slide in sand collection trough 102 through connecting rod 127, pushing sand in sand collection trough 102 out of sand delivery port and out of box 7 through opening 8. After the sand is discharged, motor 125 reverses, driving push plate 128 to reset. At the same time, flip motor drives tilt plate 111 to flip upward, so that straight plate 112 fits with the edge of sand delivery port of weighing box 101, closing sand delivery port for the next sand collection and weighing operation. Through this structural design, the accumulated sand in weighing mechanism 10 can be automatically cleaned, avoiding sand accumulation and caking, which increases the load on weighing components, reduces maintenance operations, and lowers maintenance costs and operation difficulty.

[0024] The protective cover 4 is fixedly connected to the conveying pipe 6. A bearing 5 is embedded in the protective cover 4, and the outer ring of the bearing 5 is fixedly connected to the protective cover 4. The conveying pipe 6 is fitted onto and fixedly connected to the inner ring of the bearing 5. A sand inlet is opened on one side of the sand inlet cylinder 1, and a sand filter inlet is opened on the other side. A filter screen 2 is installed at the sand filter inlet. A support rod 13 is fixedly connected to the upper end of the sand inlet cylinder 1, and a guide plate 14 is fixedly connected to the support rod 13. The guide plate 14 can drive the sand inlet cylinder 1 to rotate around the axis of the bearing 5 under wind force, ensuring that the sand inlet is always... Facing the direction of the wind and sand, the filter screen 2 at the sand filter port can filter the sand and improve the sand particle collection efficiency. When the wind and sand enter the sand inlet cylinder 1 from the sand inlet, the sand particles fall into the sand collection trough 102 of the weighing mechanism 10 through the lower sand cylinder 3 and the conveying pipe 6. The weighing sensor 9 weighs the sand particles in the sand collection trough 102 in real time, thereby realizing continuous measurement of sand flux. In the initial state, the inclined plate 111 and the straight plate 112 in the baffle mechanism 11 are in contact with the edge of the opening 8 of the box body 7 to prevent sand particles from leaking out from the sand delivery port during the sand collection process.

[0025] A side plate 114 is fixedly connected to the side end face of the straight plate 112. The side plate 114 is located on the outside of the box 7 and at the connection between the opening 8 and the straight plate 112. When the straight plate 112 is in contact with the edge of the sand feeding port of the weighing box 101 and the sand feeding port is closed, the side plate 114 can further shield the opening 8 to prevent impurities or airflow in the external environment from entering the box 7 through the opening 8 and affecting the measurement accuracy.

[0026] Workflow: When too much sand accumulates in the sand collection trough 102 of the weighing box 101 during operation, the flipping motor starts, driving the flipping shaft to rotate. Then, through the cooperation of the connecting shaft 113 and the bearing 104, the inclined plate 111 flips downward and opens the sand delivery port. Subsequently, motor 125 drives threaded rod 123 to rotate. Since one end of moving frame 126 is threadedly connected to threaded rod 123 and the other end is slidably connected to slide rod 124, the rotation of threaded rod 123 causes moving frame 126 to move along slide rod 124. Moving frame 126 drives push plate 128 to slide in sand collection trough 102 through connecting rod 127, pushing sand in sand collection trough 102 out of sand delivery port and out of box 7 through opening 8. After the sand is discharged, motor 125 reverses, driving push plate 128 to reset. At the same time, flip motor drives tilt plate 111 to flip upward, so that straight plate 112 fits with the edge of sand delivery port of weighing box 101, closing sand delivery port for the next sand collection and weighing operation. Through this structural design, the accumulated sand in weighing mechanism 10 can be automatically cleaned, avoiding sand accumulation and caking, which increases the load on weighing components, reduces maintenance operations by staff, and lowers maintenance costs and operation difficulty. A side plate 114 is fixedly connected to the side end face of the straight plate 112. The side plate 114 is located on the outside of the box 7 and at the connection between the opening 8 and the straight plate 112. When the straight plate 112 is in contact with the edge of the sand feeding port of the weighing box 101 and the sand feeding port is closed, the side plate 114 can further shield the opening 8 to prevent impurities or airflow in the external environment from entering the box 7 through the opening 8 and affecting the measurement accuracy.
