Description

Technical Field

[0001] The present invention relates to the technical field of particle silo storage detection, and in particular to an automatic particle silo depth detection device. Background Art

[0002] In the production fields of cement, aggregate, concrete, etc., material storage warehouses are indispensable process equipment in the production process. During the process of materials entering and leaving the warehouse, the dust problem is very prominent, and a large amount of dust fills the warehouse, which brings great challenges to the in-depth inspection of the material warehouse.

[0003] Currently, the industry generally uses radar level meters to monitor the depth of material silos using analog measurements. However, this detection solution has its flaws. Due to the heavy accumulation of dust and dirt in the silos, the radar level meter's signal is easily interfered with, resulting in a series of frequent fluctuations in the detection data and an inability to accurately reflect the actual situation in the silo. This leads to frequent silo blockages, which not only seriously affects production continuity and increases the cost and time of material cleaning, but can also damage production equipment, reduce production efficiency, and cause great inconvenience to the entire production process.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and an automatic detection device for the depth of a particle bin is provided in order to achieve a more practical purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an automatic detection device for the depth of a particulate matter bin, so as to solve the problem that when the depth of the material bin is monitored by the existing radar level meter analog detection method, the signal of the radar level meter is easily interfered with due to the large amount of dust and dust accumulated in the bin, resulting in a series of frequent fluctuations in the detection data and the inability to accurately reflect the actual situation in the material bin.

[0007] Furthermore, a conveyor frame is fixedly installed at the top rear position of the base frame, a loading conveyor belt is provided at the top position of the conveyor frame, an extension plate is fixedly installed at the inner lower position of the base frame, and the bottom position of the extension plate is fixedly connected to the top rear end position of the reciprocating frame.

[0008] Furthermore, a motor A is fixedly installed at the middle position of the top of the reciprocating frame, and a cam member is fixedly connected to the rotating shaft of the motor A. The cam member is located in the internal position of the reciprocating frame, and the middle protrusion position of the cam member is rotatably connected to the rear end position of the transmission plate, the front end position of the transmission plate is rotatably connected to the rear end position of the sliding plate, the sliding plate is slidably connected to the internal front position of the reciprocating frame, and the front end position of the sliding plate is fixedly connected to the middle position of the rear end of the bottom of the granular material bin.

[0009] Furthermore, a lifting frame is fixedly installed at the middle and rear position of the top of the granular material bin, a threaded hole is opened at the middle position of the top of the lifting frame, and a screw member is rotatably connected in the threaded hole of the lifting frame, the bottom position of the screw member is rotatably connected to the middle position of the top of the lifting plate, the screw member is slidably connected to the internal position of the lifting frame, and a cylinder is fixedly installed at the middle position of the bottom of the lifting plate, and the cylinder is located inside the granular material bin.

[0010] Furthermore, a matching sleeve is fixedly installed at the bottom position of the cylinder, an elastic telescopic rod is provided at the upper end position of the matching sleeve, an alarm is provided on the front and rear sides of the upper part of the matching sleeve, and the elastic telescopic rod is located in the middle of the two alarms.

[0011] Furthermore, a conical contact head is provided at the bottom of the elastic telescopic rod, which is slidably connected to the lower inner position of the matching sleeve. A docking rod is provided at the front and rear ends of the top of the contact head, and the two docking rods correspond to the two alarms one by one.

[0012] Furthermore, a control cabinet is provided at the front end of the granular material bin, and a feed port is provided at the top rear position of the granular material bin. The feed port is located at the rear position of the lifting frame and the feed port is located below the front end of the feeding conveyor belt. The control cabinet is connected to the contact switch through a wiring harness.

[0013] Furthermore, a screw conveyor is provided at a lower position inside the granular material bin, and the screw conveyor is located at a front end position on the top of the base frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the material contacts and lifts the float, a series of mechanical transmissions causes the touch rod to contact the contact switch, thereby determining whether the material capacity in the material silo has reached the range of 85%±5%. This mechanical detection method is not affected by excessive dust accumulation in the silo, and avoids the problem of frequent fluctuations in detection data due to signal interference of radar level meters. It can more accurately reflect the actual situation in the material silo and effectively reduce the occurrence of full silo blockage.

[0015] 2. The contact switch is connected to the control cabinet through a wiring harness. When the touch rod touches the contact switch, the control cabinet can automatically cut off the feeding conveyor belt and continue feeding. This automated control process does not require manual real-time monitoring, which not only saves labor costs, but also can accurately control the feeding amount, further reducing the risk of full warehouse blockage and ensuring the continuity and stability of the production process.

[0016] 3. After the material is loaded, the motor A is started to drive the cam to rotate, causing the granular material bin to oscillate back and forth on the base frame, thereby oscillating and leveling the material in the bin. This function avoids the lateral pressure on the bin body caused by the tilt of the material, extending the service life of the granular material bin, and also ensures the accuracy of subsequent detection, ensuring that the contact between the material and the float after leveling can truly reflect the material capacity in the bin.

[0017] 4. After the material inside the granular material bin is leveled, the cylinder drives the matching sleeve down to 85% of the granular material bin capacity. When the contact head contacts the material, the elastic telescopic rod contracts, causing the docking rod to contact and fit the alarm. The alarm emits a warning sound, realizing a secondary detection of the material bin capacity. This secondary detection mechanism further improves the accuracy of the detection and provides a doubly guaranteed guarantee that the material bin capacity is within the appropriate range.

[0018] 5. A screw conveyor is installed at the bottom of the granular material bin. When the granular material bin is unloading, the screw conveyor can transfer and transport the materials, effectively avoiding the accumulation of materials inside the granular material bin and causing blockage, ensuring the smooth transportation of materials and improving production efficiency.

The bottom position of the screw member 401 is rotatably connected to the middle position of the top of the lifting plate 402, and the screw member 401 is slidably connected to the internal position of the lifting frame 4. A cylinder 403 is fixedly installed at the middle position of the bottom of the lifting plate 402, and the cylinder 403 is located inside the granular material bin 2.

[0029] Among them, a matching sleeve 404 is fixedly installed at the bottom position of the cylinder 403, and an elastic telescopic rod 441 is provided at the upper end position inside the matching sleeve 404. An alarm 405 is provided on the front and back sides of the upper part of the matching sleeve 404, and the elastic telescopic rod 441 is located in the middle position between the two alarms 405.

[0030] Among them, a conical contact head 406 is provided at the bottom position of the elastic telescopic rod 441, and the contact head 406 is slidably connected to the lower position inside the matching sleeve 404. A docking rod 407 is provided at the front and rear ends of the top of the contact head 406, and the two docking rods 407 correspond one-to-one to the two alarms 405.

[0031] Among them, a control cabinet 201 is set at the front end position of the granular material bin 2, and a feed port 202 is set at the top rear position of the granular material bin 2. The feed port 202 is located at the rear position of the lifting frame 4, and the feed port 202 is located at the lower front end position of the loading conveyor belt 102. The control cabinet 201 is connected to the contact switch 308 through a wiring harness.

[0032] Among them, a screw conveyor 203 is provided at the lower position inside the granular material bin 2, and the screw conveyor 203 is located at the front end position of the top of the base frame 1. When the granular material bin 2 is unloading, the material is transferred and transported by the screw conveyor 203 to avoid the accumulation of materials inside the granular material bin 2 and blockage.

[0033] When using: When loading the granular material bin 2, the material is placed above the loading conveyor belt 102, and the loading conveyor belt 102 transfers the material to the feed port 202 and then enters the internal position of the granular material bin 2 for collection. Combined with the position of the feed port 202 at the rear of the top of the granular material bin 2, the material entering the granular material bin 2 will be at a slope with a low front and a high back, until the material inside the granular material bin 2 contacts the float 307. Combined with the material slope, the material will lift the float 307 during the loading process. Combined with the spring 306 connected to the float 307, it provides a means of assisting the float 307. At the same time, when the float 307 is lifted upward, the pulling force rod 305 rotates forward at the front position of the bottom of the detection frame 3; When the force-bearing rod 305 rotates forward under the traction of the float 307, the force-bearing rod 305 drives the bottom position of the swing rod 302 to move forward through the cooperation of the connecting rod 304. Combined with the rear end position of the support plate 301 and the rotation connection with the upper middle position of the swing rod 302, the top position of the swing rod 302 drives the touch rod 303 to move backward until the touch rod 303 contacts the contact switch 308. The contact switch 308 is connected to the control cabinet 201 through the wiring harness, cutting off the continued feeding of the feeding conveyor belt 102, thereby avoiding full warehouse blockage.

[0034] After the loading inside the granular material bin 2 is completed, the starting motor A105 drives the cam part 106 to rotate. Through the cooperation of the cam part 106 and the transmission plate 107, the sliding plate 108 slides back and forth at the internal front end position of the reciprocating frame 104. The granular material bin 2 connected to the sliding plate 108 oscillates as a whole in the front and back positions at the top front end of the base frame 1, and the material inside the granular material bin 2 is oscillated and leveled to prevent the tilt of the material inside the granular material bin 2 from causing lateral pressure on the granular material bin 2. At the same time, if the contact between the material and the float 307 after leveling can still ensure that the contact switch 308 is in contact with the touch rod 303, it is ensured that the internal capacity of the granular material bin 2 accurately reaches the suitable accommodation range.

[0035] After the material inside the granular material bin 2 is leveled, the cylinder 403 extends and drives the matching sleeve 404 to drop to 85% of the capacity of the granular material bin 2. When the contact head 406 contacts the material in the granular material bin 2, the elastic telescopic rod 441 will contract, and the two docking rods 407 of the contact head 406 will contact and fit with the two alarms 405. The two alarms 405 emit warning sounds to determine that the capacity of the granular material bin 2 meets the standard and appropriate range, thereby achieving a secondary detection effect and ensuring the accuracy of the detection.
