Abstract

This invention relates to the field of material conveying equipment, and more particularly to a material conveying device for a production silo based on a material discharge valve. The technical solution includes a gate, the top of which is rotatably connected to the material discharge valve body. A steel cable is fixedly installed on the side of the gate, and a counterweight is fixedly installed at the end of the steel cable. A hydraulic transmission component is provided between the rotating block and the counterweight. A rotating block is rotatably connected to the bottom of the sealing block. When raw materials are flowing normally through the material discharge valve body, the gate opens due to the impact of the raw materials. When the material discharge valve body is blocked, the gate is no longer impacted by the raw materials. At this time, the counterweight slides downward under gravity. The counterweight uses the hydraulic transmission component to rotate the rotating block, thereby causing the lifting block to move up and down, moving the elliptical rod and the conical head upward. This clears the blockage at the connection between the raw material silo and the sealing block, preventing compacted raw materials from causing further blockage.

Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a material conveying device for production silos based on a material discharge valve. Background Technology

[0002] A material hopper is a device used in industrial production to store and temporarily store materials and to discharge them in an orderly manner. It is usually used in conjunction with a discharge valve, conveying device, etc., to form a complete material storage and conveying system, ensuring a stable supply and precise control of materials during the production process. The discharge valve precisely controls the discharge amount and speed of materials by controlling the screw speed, rotation angle, or lifting height, meeting the requirements of different production processes and suitable for occasions with strict requirements on the amount of materials to be discharged.

[0003] Patent document CN111908166A proposes a hopper discharge mechanism that uses the rotation of a screw to move a threaded sleeve, which in turn adjusts the position of a moving rod. This moving rod then adjusts the position of the upper guide plate, effectively guiding and discharging the coal. In this prior art, the accumulated production material in the hopper can become stuck at the connection between the hopper and the discharge mechanism, causing blockages during discharge and hindering normal material transport. Summary of the Invention

[0004] The purpose of this invention is to address the problem of blockage caused by long-term accumulation of production materials in the prior art, and to propose a production material silo conveying device based on a discharge valve.

[0005] The technical solution of the present invention: A production material silo conveying device based on a discharge valve, applied to a raw material silo, wherein a discharge valve body is fixedly installed at the bottom center of the raw material silo, and a sealing plug for sealing the pipeline is slidably connected inside the discharge valve body, and further includes:

[0006] The instant unblocking unit includes a gate, the top of which is rotatably connected to a discharge valve body. A steel cable is fixedly installed on the side of the gate, and a counterweight is fixedly installed at the end of the steel cable. A hydraulic transmission component is provided between the rotating block and the counterweight. A rotating block is rotatably connected to the bottom of the sealing block. A guide rail is provided on the rotating block, and a lifting block that slides up and down inside the sealing block is embedded in the guide rail.

[0007] The insertion part includes an elliptical rod, the bottom of which is fixedly connected to a lifting block, and a conical insertion head is fixedly installed on the top of the elliptical rod.

[0008] An adjusting disc is fixedly installed at the bottom of the sealing plug, and the outer wall of the adjusting disc is threadedly connected to the discharge valve body.

[0009] Optionally, the guide rail adopts a ring-shaped wave structure, and a portion of the lifting block embedded inside the guide rail is rotatably connected to a ball bearing, which rolls along the guide rail.

[0010] Optionally, the hydraulic transmission component includes a manual hydraulic pump, which is fixedly installed inside the discharge valve body and located below the counterweight. A hydraulic telescopic rod is fixedly installed at the bottom of the sealing block. The manual hydraulic pump is connected to the hydraulic telescopic rod through a hydraulic pipe. A toothed plate is fixedly installed at the end of the hydraulic telescopic rod. A gear is fixedly installed at the bottom of the rotating block, and the gear meshes with the toothed plate.

[0011] Optionally, the diameter of the manual hydraulic pump is larger than the diameter of the hydraulic telescopic rod, and the diameter of the gear is smaller than the diameter of the rotating block.

[0012] Optionally, a fixed pulley supporting a steel cable is rotatably connected to the inner wall of the discharge valve body, and a push rod is slidably connected inside the discharge valve body. The bottom of the push rod abuts against the top of the adjusting disc, and the top of the push rod contacts the bottom of the counterweight.

[0013] Optionally, a pull plate is rotatably connected to the arc surface of the elliptical rod. Multiple pull plates are provided and are distributed in a ring at equal angles on the outer arc surface of the elliptical rod. A folding piece is fixedly installed between two adjacent pull plates.

[0014] Optionally, the bottom diameter of the conical head is larger than the diameter of the elliptical rod, the pull plate is located below the conical head, and an anti-full folding block is fixedly installed in the middle of the elliptical rod.

[0015] Optionally, the top of the sealing plug is provided with a flow guide groove, the conical head slides up and down in the flow guide groove, and a conveying protective bag is fixedly installed between the bottom of the sealing plug and the discharge valve body.

[0016] Optionally, the sealing block is provided with a dead corner cleaning section inside. The dead corner cleaning section includes a semi-circular receiving groove. The semi-circular receiving groove is opened inside the sealing block. A fixing block is fixedly installed inside the semi-circular receiving groove. A lifting block is slidably connected to the inside of the semi-circular receiving groove.

[0017] Optionally, a slope forming rod is fixedly installed inside the discharge valve body. The top of the slope forming rod is fixedly connected to the lifting block 2. An elastic protective plate is fixedly installed on the top of the fixed block and the semi-circular receiving groove. The elastic protective plate closes the semi-circular receiving groove.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] When raw materials are flowing normally through the discharge valve body, the baffle is opened by the impact of the raw materials. When the discharge valve body is blocked, the baffle is no longer impacted by the raw materials. At this time, the counterweight slides downward under the action of gravity. The counterweight uses a hydraulic transmission component to make the rotating block rotate, thereby causing the lifting block to move up and down and move the elliptical rod and the conical head upward, thereby clearing the raw materials blocked at the connection between the raw material bin and the sealing block, and avoiding the blockage caused by the compacted raw materials in the raw material bin.

[0020] This invention utilizes the resistance of the material when the elliptical rod moves upward, causing the pull plate to change from a horizontal state to a folded state. When the elliptical rod moves downward, the pull plate changes from a folded state to a horizontal state due to the resistance, thereby pulling the material downward. This avoids the inability to completely clear blockages when the conical head directly penetrates the material.

[0021] During the downward movement of the sealing block, the slope forming rod lifts the lifting block, and the lifting block and the fixed block form a slope. The elastic protective plate tilts, and the adjusting plate forms an inclined surface towards the outlet of the discharge valve body. This avoids a dead angle at the top of the sealing block and on the right side, preventing the raw material at this position from being unable to be discharged, which would lead to expiration and contamination of new raw materials.

[0031] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] like Figures 1 to 6As shown, this invention proposes a material conveying device for a production silo based on a discharge valve, applied to a raw material silo 1. A discharge valve body 3 is fixedly installed at the bottom center of the raw material silo 1. A sealing plug 2 is slidably connected inside the discharge valve body 3. An adjusting disc 4 is fixedly installed at the bottom of the sealing plug 2, and the outer wall of the adjusting disc 4 is threadedly connected to the discharge valve body 3. By rotating the adjusting disc 4, the sealing plug 2 slides downward, thereby opening the discharge valve body 3 to discharge the production raw materials.

[0037] In one embodiment, the discharge valve body 3 is provided with an instant unblocking section 5 inside. The instant unblocking section 5 includes a baffle 51. The top of the baffle 51 is rotatably connected to the discharge valve body 3. A steel cable 52 is fixedly installed on the side of the baffle 51. A counterweight block 53 is fixedly installed at the end of the steel cable 52. A fixed pulley supporting the steel cable 52 is rotatably connected to the inner wall of the discharge valve body 3.

[0038] The discharge valve body 3 is internally connected to a push rod 54, the bottom of which rests against the top of the adjusting disc 4, and the top of which contacts the bottom of the counterweight 53. When the sealing plug 2 closes the discharge valve body 3, the push rod 54 rests against the bottom of the counterweight 53, preventing the counterweight 53 from sliding downwards. When the sealing plug 2 does not close the discharge valve body 3, and raw material is discharged from the outlet of the discharge valve body 3, the raw material impacts the baffle 51, causing it to rotate. The baffle 51 rotates and uses the steel cable 52 to pull the counterweight 53 upwards. When there is a blockage, the baffle 51 is no longer impacted by the raw material, and the counterweight 53 slides downwards under the action of gravity.

[0039] A rotating block 58 is rotatably connected to the bottom of the sealing block 2. A hydraulic transmission component is provided between the rotating block 58 and the counterweight block 53. A guide rail 59 is provided on the rotating block 58. A lifting block 510 that slides up and down inside the sealing block 2 is embedded in the guide rail 59.

[0040] In one embodiment, the hydraulic transmission component includes a manual hydraulic pump 55, which is fixedly installed inside the discharge valve body 3. The manual hydraulic pump 55 is located below the counterweight 53. A hydraulic telescopic rod 56 is fixedly installed at the bottom of the sealing block 2. The manual hydraulic pump 55 is connected to the hydraulic telescopic rod 56 through a hydraulic pipe. A toothed plate 57 is fixedly installed at the end of the hydraulic telescopic rod 56. A gear is fixedly installed at the bottom of the rotating block 58, and the gear meshes with the toothed plate 57.

[0041] When the raw material is blocked, the gate 51 is no longer impacted by the raw material. At this time, the counterweight 53 slides down under the action of gravity. The counterweight 53 presses down on the manual hydraulic pump 55 to squeeze the hydraulic oil inside into the hydraulic telescopic rod 56. The hydraulic telescopic rod 56 extends and causes the toothed plate 57 to drive the rotating block 58 to rotate. Since the guide rail 59 adopts a ring wave structure, the lifting block 510 will move up and down reciprocatingly when it moves along the guide rail 59.

[0042] The top of the sealing plug 2 is provided with an insertion part 6, which includes an elliptical rod 61. The bottom of the elliptical rod 61 is fixedly connected to the lifting block 510, and a conical head 64 is fixedly installed on the top of the elliptical rod 61. By the reciprocating movement of the lifting block 510, the elliptical rod 61 and the conical head 64 are moved upward.

[0043] The diameter of the manual hydraulic pump 55 is larger than that of the hydraulic telescopic rod 56, and the diameter of the gear is smaller than that of the rotating block 58. When the manual hydraulic pump 55 is compressed a short distance, the hydraulic telescopic rod 56 extends a long distance, and the rotation number of the rotating block 58 is increased by using the gear ratio.

[0044] In this invention, when raw materials are flowing normally through the discharge valve body 3, the baffle 51 is opened by the impact of the raw materials; when the discharge valve body 3 is blocked, the baffle 51 is no longer impacted by the raw materials. At this time, the counterweight 53 slides downward under the action of gravity. The counterweight 53 uses a hydraulic transmission component to make the rotating block 58 rotate, thereby causing the lifting block 510 to move up and down and reciprocate, causing the elliptical rod 61 and the conical head 64 to move upward, thereby clearing the raw materials blocked at the connection between the raw material bin 1 and the sealing block 2, and preventing the compacted raw materials in the raw material bin 1 from causing blockage.

[0045] like Figure 5 and Figure 6 As shown, the present invention proposes a production silo conveying device based on a discharge valve. A pull plate 62 is rotatably connected to the arc surface of an elliptical rod 61. Multiple pull plates 62 are provided and are distributed in a ring at equal angles on the outer arc surface of the elliptical rod 61. A folding piece 63 is fixedly installed between two adjacent pull plates 62.

[0046] like Figure 8 As shown, when the elliptical rod 61 moves upward, the pull plate 62 is pushed downward by the raw material, and the pull plate 62 changes from a horizontal state to a downward tilted state. When the elliptical rod 61 moves downward, the pull plate 62 is pushed upward by the raw material, and changes from a tilted state to a horizontal state.

[0047] The bottom diameter of the conical head 64 is larger than the diameter of the elliptical rod 61 to prevent the folding piece 63 from folding upwards. The pull plate 62 is located below the conical head 64. An anti-full folding block 65 is fixedly installed in the middle of the elliptical rod 61 to prevent the pull plate 62 from completely adhering to the elliptical rod 61 and preventing it from unfolding.

[0048] The top of the sealing plug 2 is provided with a guide groove 66, and the conical head 64 slides up and down in the guide groove 66. The guide groove 66 is inclined to discharge the raw material and prevent the raw material from entering the area below the pull plate 62 and forming a dead corner. A conveying protective bag 67 is fixedly installed between the bottom of the sealing plug 2 and the discharge valve body 3 to prevent the raw material from entering the area below the sealing plug 2. The manual hydraulic pump 55 has an automatic reset function, which can reset the elliptical rod 61 and the conical head 64. When there is no blockage, the elliptical rod 61 will not extend upward to avoid affecting the flow of raw material from the sealing plug 2.

[0049] When the elliptical rod 61 moves upward, the pull plate 62 is resisted by the raw material and changes from a horizontal state to a folded state. When the elliptical rod 61 moves downward, the pull plate 62 is resisted and changes from a folded state to a horizontal state, thereby pulling the raw material downward. This avoids the situation where the conical head 64 directly pierces the raw material and cannot completely clear the blockage.

[0050] like Figures 5 to 7 As shown, the present invention proposes a production silo conveying device based on a discharge valve. The sealing block 2 is provided with a dead corner cleaning part 7. The dead corner cleaning part 7 includes a semi-circular receiving groove 71. The semi-circular receiving groove 71 is opened inside the sealing block 2. A fixing block 72 is fixedly installed inside the semi-circular receiving groove 71. A lifting block 73 is slidably connected to the semi-circular receiving groove 71.

[0051] By using the lifting block 2 73 to slide upward, the lifting block 2 73 and the fixed block 72 form a slope and tilt, avoiding the dead corner at the top of the sealing block 2 and the right side, and preventing the raw material in that position from being unable to be discharged.

[0052] A slope forming rod 75 is fixedly installed inside the discharge valve body 3. The top of the slope forming rod 75 is fixedly connected to the lifting block 73. An elastic protective plate 74 is fixedly installed on the top of the fixed block 72 and the semi-circular receiving groove 71. The elastic protective plate 74 closes the semi-circular receiving groove 71.

[0053] When the sealing plug 2 moves downward to open the discharge valve body 3, during the downward movement of the sealing plug 2, the slope forming rod 75 lifts the lifting block 73. The elastic protective plate 74 is elastic. Under the action of the lifting block 73 and the fixed block 72, the elastic protective plate 74 forms an inclined surface that tilts towards the outlet of the discharge valve body 3.

[0054] During the downward movement of the sealing block 2, the slope forming rod 75 lifts the lifting block 73, and the lifting block 73 and the fixed block 72 form a slope. The elastic protective plate 74 tilts, and the adjusting plate 4 forms an inclined surface towards the outlet of the discharge valve body 3. This avoids a dead angle at the top of the sealing block 2 and on the right side, preventing the raw material at this position from being unable to be discharged, resulting in expiration and contamination of new raw materials.

[0055] When the discharge valve body 3 is blocked, the raw material flows normally under the action of gravity, and the baffle 51 is opened by the impact of the raw material. The baffle 51 uses the steel cable 52 to pull the counterweight 53 upward. The counterweight 53 has no contact with the manual hydraulic pump 55. When the discharge valve body 3 is blocked, the baffle 51 is no longer impacted by the raw material, and the baffle 51 no longer uses the steel cable 52 to pull the counterweight 53. At this time, the counterweight 53 slides downward under the action of gravity. The counterweight 53 presses down on the manual hydraulic pump 55 to squeeze the hydraulic oil inside into the hydraulic telescopic rod 56. The hydraulic telescopic rod 56 extends and causes the toothed plate 57 to drive the rotating block 58 to rotate. Since the guide rail 59 adopts a ring wave structure, the lifting block 510 will move up and down reciprocatingly when it moves along the guide rail 59. This reciprocating motion of the lifting block 510 causes the elliptical rod 61 and the conical head 64 to move upward, thereby clearing the raw material blockage at the connection between the raw material bin 1 and the sealing block 2.

[0056] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
