Description

Technical Field

[0001] This utility model belongs to the field of hopper technology, specifically relating to a direct-discharge gypsum ore hopper. Background Technology

[0002] As a basic raw material in building materials, chemical raw materials and other fields, gypsum ore relies on hoppers for continuous "loading-temporary storage-unloading" operations during its mining and transportation. The unloading efficiency and anti-clogging performance of the hoppers directly affect the production rhythm. In order to facilitate the direct unloading of materials in the hoppers after the hoppers are moved to the unloading location without tipping the hoppers, direct discharge hoppers are often used for loading and unloading gypsum ore.

[0003] When powdery particles in gypsum ore mix with lumpy ore, they easily form an "arch blockage" at the hopper discharge channel (usually a conical constriction structure). The lumpy ore supports each other to form an arch, with the powdery ore filling the gaps, causing discharge interruption. Current methods for clearing this blockage mostly involve manually tapping the hopper's outer wall or inserting a steel rod to pry it open. This is not only time-consuming and labor-intensive, but the tapping can also deform the hopper and crack the welds. Furthermore, inserting the steel rod poses a safety hazard due to flying ore that could injure people. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a direct-discharge gypsum ore hopper. When using this device, if ore blockage occurs during the unloading process, the operator can easily drive the agitator located in the hopper body and the discharge channel to repeatedly break up the blockage and restore smooth unloading. Compared with traditional unblocking methods, this is more labor-saving, faster, and safer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a direct-discharge gypsum ore hopper, comprising a hopper body, a discharge channel connected to the bottom of the hopper body, a first support provided on the side of the hopper body, a lifting lug welded to the top of the hopper body, a self-unloading mechanism installed at the bottom and on both sides of the discharge channel, a transmission chamber provided on both sides of the discharge channel, a first rotating shaft rotatably mounted on the inner side of the transmission chamber, one end of the first rotating shaft passing through the side of the transmission chamber and connected to a rocker arm connector, a first gear fixedly sleeved on the outer side of the first rotating shaft, a second rotating shaft rotatably mounted on the inner side of the transmission chamber, the second rotating shaft passing through the inner side of the hopper body, a second gear fixedly sleeved on the outer side of the portion of the second rotating shaft located inside the transmission chamber where the first gear is located, the first gear and the second gear meshing with each other, the portion of the second rotating shaft located inside the transmission chamber being fixedly connected to a crankshaft, and a dredging mechanism inserted into the top of the transmission chamber.

[0006] To improve the structural strength of the hopper: As a further improvement to the above technical solution: the outer side of the hopper body is welded with reinforcing ribs.

[0007] The beneficial effects of this improvement are: the reinforcing ribs on the outside of the hopper body can enhance the structural strength of the hopper body and prevent hopper deformation.

[0008] In order to directly unload the ore from the main body of the hopper: As a further improvement to the above technical solution: the self-unloading mechanism includes pin seats installed on both sides of the discharge channel, the pin seats being rotatably connected to the discharge baffle, the discharge baffle having limit rods on both sides, the discharge channel having limit hooks rotatably installed on both sides, one end of the limit hooks being connected to a rotating arm, the discharge channel having levers rotatably installed on both sides, the lever having a sliding groove extending through its two sides near the rotating arm, the rotating arm having a sliding shaft on its side, and the sliding shaft being slidably connected to the sliding groove.

[0009] The beneficial effects of this improvement are as follows: During unloading, the operator pulls the connecting rod through the rope connected to the rope fixing hole. The connecting rod drives the levers on both sides to rotate around the rotation point. The sliding groove on the lever slides along the sliding shaft of the rotating arm, pushing the rotating arm to rotate upward. The rotating arm drives the limit hook to disengage from the limit rod, releasing the limit on the unloading baffle. Under the action of the gravity of the ore in the hopper body, the unloading baffle rotates downward around the pin seat, opening the unloading port at the bottom of the discharge channel. The ore is quickly discharged from the unloading port under the action of gravity, realizing the direct unloading function.

[0010] To facilitate opening the unloading baffle: As a further improvement to the above technical solution: a connecting rod is connected between the ends of the levers located on both sides of the discharge channel, and a rope fixing hole is fixed on one side of the connecting rod.

[0011] The beneficial effects of this improvement are: the rope fixing hole is connected to the rope, and during unloading, the connecting rod can be pulled by the rope to drive the lever to rotate and open the unloading baffle.

[0012] To enable the lever to automatically reset: As a further improvement to the above technical solution: a spring is connected between the lever and the discharge channel.

[0013] The beneficial effect of this improvement is that the spring is used for the automatic reset of the lever.

[0014] To improve the ease of operation during dredging: As a further improvement to the above technical solution: the first gear is a small gear, the second gear is a large gear, and the size and number of teeth of the first gear are smaller than those of the second gear.

[0015] The beneficial effects of this improvement are: by utilizing the gear ratio of the first gear and the second gear, speed reduction and torque increase can be achieved, thereby increasing the output torque and making it easier to lift and lower the drive telescopic rod together with the anti-blocking toggle frame.

[0016] To clear blockages during unloading: As a further improvement to the above technical solution: the unblocking mechanism includes a telescopic rod inserted from the top of the transmission chamber, a crank rotatably connected to the bottom of the telescopic rod, the crank being rotatably connected to the crankshaft, the top of the telescopic rod penetrating the inner side of the hopper body and being fixed to the second bracket, the second bracket having fixing rods at both the top and bottom, an anti-blocking actuation frame fixedly sleeved on the outer side of the fixing rod, and the rocker arm connector being inserted and connected to the rocker arm.

[0017] The beneficial effects of this improvement are as follows: If material discharge becomes obstructed during the unloading process, it can be cleared using a clearing mechanism. The operator inserts the rocker arm into the rocker arm connector, holds the rocker arm, and rotates it back and forth. The rocker arm drives the first rotating shaft to rotate within the transmission chamber via the rocker arm connector. The first gear on the outside of the first rotating shaft rotates synchronously. Since the first gear is a small gear and the second gear is a large gear, and the two mesh, the small gear drives the large gear to rotate, achieving speed reduction and torque increase. The second gear drives the second rotating shaft to rotate slowly, reducing the operator's rotational intensity. When the second rotating shaft rotates, its crankshaft located within the transmission chamber rotates accordingly. The crankshaft pulls the telescopic rod along the insertion hole at the top of the transmission chamber, sliding it up and down. The second bracket at the top of the telescopic rod drives the fixed rods on both sides to rise and fall synchronously. The agitator on the outer sleeve of the fixed rod moves the ore in the hopper up and down, breaking up the accumulated and blocked ore, allowing it to flow smoothly into the discharge channel, thus ensuring smooth unloading.

[0018] In order to move the ore up and down in the hopper body and the discharge channel: As a further improvement to the above technical solution: the anti-blocking toggle frame includes a sleeve welded to the outside of the fixed rod, and multiple toggle pieces are welded to the outside of the sleeve.

[0019] The beneficial effects of this improvement are: the agitator is used to move the ore in the hopper body and the discharge channel up and down, breaking up the accumulated and blocked ore, and allowing the ore to flow smoothly into the discharge channel.

[0020] In summary, the beneficial effects of this device are as follows: when using this device, if ore blockage occurs during the unloading process, the rocker arm can be inserted immediately to activate the unblocking mechanism. Through the reduction and torque-increasing structure of the small gear driving the large gear, the operator can easily drive the agitator located in the hopper body and the discharge channel to repeatedly break up and disperse the blockage ore, restoring smooth unloading. Compared with the traditional method of manually using a hammering tool to knock on the hopper or inserting a steel rod into the hopper for unblocking, this method is more labor-saving, faster, and safer.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0024] like Figure 1-5As shown, a direct-discharge gypsum ore hopper includes a hopper body 11. A discharge channel 12 is connected to the bottom of the hopper body 11. A first support 13 is provided on the side of the hopper body 11. A lifting lug 15 is welded to the top of the hopper body 11. A self-unloading mechanism is installed at the bottom and on both sides of the discharge channel 12. A transmission chamber 31 is provided on both sides of the discharge channel 12. A first rotating shaft 32 is rotatably mounted inside the transmission chamber 31. One end of the first rotating shaft 32 passes through the side of the transmission chamber 31 and connects to a rocker arm connector 312. The first rotating shaft 32 is fixedly sleeved with a first gear 33 on its outer side. A second rotating shaft 35 is rotatably installed on the inner side of the transmission chamber 31. The second rotating shaft 35 passes through the inner side of the hopper body 11. The portion of the second rotating shaft 35 located inside the transmission chamber 31 with the first gear 33 has a second gear 34 fixedly sleeved on its outer side. The first gear 33 and the second gear 34 mesh with each other. The portion of the second rotating shaft 35 located inside the transmission chamber 31 is fixedly connected to the crankshaft 36. The top of the transmission chamber 31 is inserted and connected to the unblocking mechanism.

[0025] When using this device, if ore blockage occurs during unloading, the rocker arm 313 can be inserted immediately to activate the unblocking mechanism. Through the deceleration and torque-increasing structure of the small gear driving the large gear, the operator can easily drive the agitator 315 located in the hopper body 11 and the discharge channel 12 to reciprocate up and down to disperse the blockage ore and restore the smoothness of unloading. Compared with the traditional method of manually using a hammering tool to knock on the hopper or inserting a steel rod into the hopper for unblocking, it is more labor-saving, faster and safer.

[0026] The outer side of the hopper body 11 is welded with reinforcing ribs 14.

[0027] The reinforcing ribs 14 on the outer side of the hopper body 11 can enhance the structural strength of the hopper body 11 and prevent the hopper from deforming.

[0028] The self-unloading mechanism includes pin seats 21 installed on both sides of the discharge channel 12. The pin seats 21 are rotatably connected to the discharge baffle 22. Limiting rods 23 are provided on both sides of the discharge baffle 22. Limiting hooks 24 are rotatably installed on both sides of the discharge channel 12. One end of the limiting hook 24 is connected to a rotating arm 25. A lever 26 is rotatably installed on both sides of the discharge channel 12. A sliding groove 27 is provided between the two sides of the lever 26 near the rotating arm 25. A sliding shaft 28 is provided on the side of one end of the rotating arm 25. The sliding shaft 28 is slidably connected to the sliding groove 27.

[0029] During unloading, the operator pulls the connecting rod 29 through the rope connected to the rope fixing hole 210. The connecting rod 29 drives the levers 26 on both sides to rotate around the rotation point. The sliding groove 27 on the lever slides along the sliding shaft 28 of the rotating arm 25, pushing the rotating arm 25 to rotate upward. The rotating arm 25 drives the limit hook 24 to disengage from the limit rod 23, releasing the limit on the unloading baffle 22. Under the action of the gravity of the ore in the hopper body 11, the unloading baffle 22 rotates downward around the pin seat 21, opening the unloading port at the bottom of the discharge channel 12. The ore is quickly discharged from the unloading port under the action of gravity, realizing the direct unloading function.

[0030] A connecting rod 29 is connected between the ends of the levers 26 located on both sides of the discharge channel 12, and a rope fixing hole 210 is fixed on one side of the connecting rod 29.

[0031] The rope fixing hole 210 is connected to the rope. During unloading, the connecting rod 29 can be pulled by the rope to drive the lever 26 to rotate and open the unloading baffle 22.

[0032] A spring 211 is connected between the lever 26 and the discharge channel 12.

[0033] Spring 211 is used to automatically reset lever 26.

[0034] The first gear 33 is a small gear, and the second gear 34 is a large gear. The size and number of teeth of the first gear 33 are smaller than those of the second gear 34.

[0035] By utilizing the gear ratio between the first gear 33 and the second gear 34, speed reduction and torque increase can be achieved, thereby increasing the output torque and making it easier to lift and lower the drive telescopic rod 37 together with the anti-blocking toggle frame 311.

[0036] The unblocking mechanism includes a telescopic rod 37 inserted from the top of the transmission chamber 31. A crank 38 is rotatably connected to the bottom of the telescopic rod 37. The crank 38 is rotatably connected to the crankshaft 36. The top of the telescopic rod 37 passes through the inner side of the feed hopper body 11 and is fixed to the second bracket 39. The top and bottom of the second bracket 39 are provided with fixing rods 310. An anti-blocking actuation frame 311 is fixedly sleeved on the outer side of the fixing rod 310. The rocker arm joint 312 is inserted and connected to the rocker arm 313.

[0037] The anti-blocking toggle bracket 311 includes a sleeve 314 welded to the outside of the fixed rod 310, and a plurality of toggle pieces 315 are welded to the outside of the sleeve 314.

[0038] The agitator 315 is used to move the ore in the hopper body 11 and the discharge channel 12 up and down, breaking up the accumulated and blocked ore, so that the ore can flow smoothly into the discharge channel 12.

[0039] Working principle and usage process of this utility model: Using a lifting device, the hoisting tool is connected to the lifting lug 15 of this device to lift the hopper to the receiving position. At this time, the discharge baffle 22 at the bottom of the discharge channel 12 is in a closed state. The limit hook 24 and the limit rods 23 on both sides of the discharge baffle limit each other to lock and seal the discharge port, preventing the ore from leaking out during the loading process. The gypsum ore is poured from the top of the hopper body 11, and the ore accumulates inside the hopper body. The reinforcing ribs 14 on the outside of the hopper body 11 can enhance the structural strength of the hopper body 11 and prevent the hopper from deforming. After the loading is completed, this device can be lifted away from the receiving position or transferred to the storage point. The device can be placed stably on the ground by the first support 13, or transferred to the unloading point for unloading. During unloading, the operator pulls the connecting rod 29 through the pull rope connected to the rope fixing hole 210. The connecting rod 29 drives the levers 26 on both sides to rotate around the rotation point. The sliding groove 27 on the lever slides along the sliding shaft 28 of the rotating arm 25. The rotating arm 25 is pushed to rotate upward, and the rotating arm 25 drives the limit hook 24 to disengage from the limit rod 23, releasing the limit on the discharge baffle 22. Under the action of the gravity of the ore in the hopper body 11, the discharge baffle 22 rotates downward around the pin seat 21, opening the discharge port at the bottom of the discharge channel 12. The ore is quickly discharged from the discharge port under the action of gravity, realizing the direct discharge function. If the discharge is not smooth during the discharge process, it can be cleared by the unblocking mechanism. The operator inserts the rocker arm 313 into the rocker arm joint 312, holds the rocker arm 313 and rotates it back and forth. The rocker arm 313 drives the first rotating shaft 32 to rotate in the transmission chamber 31 through the rocker arm joint 312. The first gear 33 on the outside of the first rotating shaft 32 rotates synchronously. Since the first gear is a small gear and the second gear 34 is a large gear, and the two are meshed, the small gear drives the large gear to rotate to achieve deceleration and torque increase. The second gear 34 drives the second rotating shaft 35 to rotate slowly, reducing the rotation intensity of the operator. When the second rotating shaft 35 rotates, the crankshaft 36 located in the transmission chamber 31 rotates accordingly. The crankshaft 36 pulls the telescopic rod 37 through the crank 38 to slide up and down along the insertion hole at the top of the transmission chamber 31. The second bracket 39 at the top of the telescopic rod 37 drives the fixed rods 310 on both sides to rise and fall synchronously. The actuating plate 315 on the outer sleeve 314 of the fixed rod 310 moves up and down to agitate the ore in the hopper, breaking up the accumulated and blocked ore, allowing the ore to flow smoothly into the discharge channel 12, thus unloading smoothly. After unloading is completed, the rocker arm 3 stops rotating. 13. Remove it and lower the hopper body 11 to the ground. During this process, the unloading baffle 22 will automatically close under the pressure of the hopper body 11. At the same time as closing, pull the connecting rod 29 again to make the limit hook 24 give way to the limit rod 23. After the unloading baffle 22 is closed, the connecting rod 29 can be released. Under the rebound force of the spring 211, the lever 26 will be reset and the limit hook 24 will be engaged with the limit rod 23 again. Finally, the device can be hoisted to the storage location or hoisted back to the receiving location.
