[0002] After mining, mines will obtain a lot of ores, but these ores are usually large in volume and need to be crushed. The crushing process is divided into coarse crushing, medium crushing and fine crushing. Generally, ore crushers are used to perform coarse crushing of these ores.

[0003] A Chinese patent with authorization announcement number CN210729785U discloses an energy-saving multi-stage crushing device for mineral mining, including a processing table, a cylinder fixed to the top wall of the processing table, a hammer fixed to the bottom of the cylinder, a bottom box fixed to the bottom wall of the processing table, a drawer provided inside the drawer, and a third crushing box fixed on the top of the bottom box. The utility model is provided with a first crushing box, a second crushing box and a third crushing box. Through the first crushing box, the second crushing box and the third crushing box, the mineral can be crushed three times, so that the mineral crushing is more sufficient, and through the distribution of the three groups of spiral crushing rods in the second crushing box, the mineral inside the second crushing box can be more fully crushed, further improving the crushing efficiency. At the same time, the crushing rods in the third crushing box are composed of a crushing main rod and four rows of crushing support rods. When crushing the mineral, the mineral is fully crushed again, once again improving the crushing efficiency.

[0004] Regarding the above-mentioned related technologies, when the crushed ore is discharged, a large amount of dust is generated, and the dust enters the working environment, affecting the working environment. Utility Model Content

[0005] In order to reduce dust entering the working environment, the present application provides a discharging device for an ore crusher.

[0006] The discharging device of an ore crusher provided in this application adopts the following technical solution:

[0007] A discharging device of an ore crusher comprises a frame and a discharging hopper connected to the frame, a discharge port being provided at the bottom of the discharging hopper, a top of the discharging hopper being connected to the discharge port of a crusher body, the frame being connected to a conveyor belt, the conveyor belt being arranged below the discharging hopper, the frame being connected to a dust cover, the length direction of the dust cover being consistent with the length direction of the conveyor belt, the dust cover being arranged above the conveyor belt, the discharging hopper being connected to one end of the dust cover, the dust cover being provided with a connection port for material to pass through along its length direction and away from one end of the discharging hopper, a nozzle being connected inside the dust cover, and a water outlet of the nozzle facing the conveyor belt.

[0008] By adopting the above technical solution, the material is discharged from the hopper to the conveyor belt, and the conveyor belt drives the material to be transported. When the material falls onto the conveyor belt, a large amount of dust is easily generated. The addition of a dust cover can prevent dust from entering the working environment as much as possible, reducing the pollution of dust to the working environment. When the material is transported along the conveyor belt, the nozzle sprays water to the material on the surface of the conveyor belt, thereby reducing the dust generated during the material transportation process and further reducing the pollution of dust to the working environment.

[0009] Optionally, a guide plate is connected to the discharge hopper, one end of the guide plate is rotatably connected to the inner wall of the discharge hopper, and the other end of the guide plate is tilted toward the side close to the discharge port. The discharge hopper is connected to a shock absorbing assembly, which is used to reduce the impact of the material on the guide plate.

[0010] By adopting the above technical solution, when the material enters the discharge hopper, the guide plate acts as a buffer for impurities, thereby slowing down the movement of the material, reducing the impact of the material on the conveyor belt, reducing the dust generated, and further reducing the dust entering the working environment.

[0011] Optionally, a buffer plate is rotatably connected in the discharge port, the guide plate is arranged above the buffer plate, the buffer plate is arranged in a spiral shape, and the buffer plate is used to guide the material to be discharged to the surface of the conveyor belt.

[0012] By adopting the above technical solution, the material enters the feed hopper, moves along the guide plate and approaches the buffer plate, and the material falling on the surface of the buffer plate moves along the buffer plate to the conveyor belt, thereby reducing the mutual collision between the materials, further reducing the dust generated during material transportation, and reducing the damage caused by the collision of the material with the conveyor belt.

[0013] Optionally, a support plate is connected to the discharge hopper, and the shock absorbing assembly includes a sliding rod and a first spring. The length direction of the sliding rod is consistent with the vertical direction. The sliding rod passes through and is slidably connected to the support plate in the vertical direction. The sliding rod is arranged under the guide plate, and the top of the sliding rod contacts the guide plate. The length direction of the first spring is consistent with the vertical direction. The first spring is sleeved on the sliding rod, one end of the first spring is connected to the support plate, and the other end of the first spring is connected to the sliding rod.

[0014] By adopting the above technical solution, the material enters the feed hopper and falls to the top of the guide plate. The guide plate is pressed down and rotated by the gravity of the material. The guide plate pushes the sliding rod to slide downward in the vertical direction, thereby causing the first spring to deform. The first spring can fully absorb the impact force caused by the falling material, thereby reducing the damage caused by the impact of the material on the guide plate.

[0015] Optionally, a buffer block is connected to the top of the sliding rod, the buffer block is in contact with the guide plate, and the buffer block is made of a flexible material.

[0016] By adopting the above technical solution, a buffer block is added to reduce the damage caused by the collision between the buffer block and the guide plate.

[0017] Optionally, the frame is connected to a scraper, which is arranged below the conveyor belt, with the top of the scraper in contact with the bottom of the conveyor belt, and the length direction of the scraper consistent with the width direction of the conveyor belt.

[0018] By adopting the above technical solution, the material after being sprayed by the collision head is easy to stick to the surface of the conveyor belt after long-term use. A scraper is added to scrape the material off the surface of the conveyor belt during transmission, thereby reducing the material on the surface of the conveyor belt.

[0019] Optionally, the scraper is connected to moving blocks on both sides along its length direction, and the frame is provided with a moving hole, the length direction of the moving hole is consistent with the length direction of the conveyor belt, the moving hole is open at one end along its length direction, and there are two moving holes, and the moving blocks correspond to the moving holes one by one, and the moving blocks are slidably connected to the moving holes along the length direction of the conveyor belt, and a locking assembly is connected to the moving hole, and the locking assembly is used to lock the locking block in the moving hole.

[0020] By adopting the above technical solution, after long-term use, the scraper is prone to adhesion of materials or wear. When removing the scraper, the moving block is moved along the length direction of the conveyor belt, so that the moving block slides along the length direction of the conveyor belt and is connected to the moving hole, and the moving block is moved away from the moving hole, so that the scraper is moved away from the frame, thereby facilitating the cleaning and replacement of the scraper.

[0021] Optionally, an installation groove is opened on the inner wall of one side of the movable hole in the vertical direction, and the length direction of the installation groove is consistent with the vertical direction. The locking assembly includes a second spring and a locking block. The length direction of the second spring is consistent with the vertical direction. One end of the second spring is connected to the inner wall of the installation groove, and the other end of the second spring is connected to the locking block. The locking block is slidably connected to the installation groove along the vertical direction, and the locking block contacts the inner wall of the movable hole away from one end of the second spring. When the locking block contacts the inner wall of the movable hole, the second spring is squeezed and deformed.

[0022] By adopting the above technical solution, when installing the scraper, the locking block is pressed downward in the vertical direction, so that the locking block is embedded in the installation groove, and the second spring is squeezed and deformed, so that the moving block can slide in the moving hole along the length direction of the conveyor belt. When one end of the moving block reaches one end of the moving hole along the length direction of the moving hole, the locking block is released, the second spring restores its shape and pushes the locking block to move upward in the vertical direction, thereby driving the locking block to contact the inner wall of the moving hole, so that the moving block is stably connected to the moving hole.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The material is discharged from the hopper to the conveyor belt, which drives the material to be transported. When the material falls onto the conveyor belt, a large amount of dust is likely to be generated. The addition of a dust cover can prevent dust from entering the working environment as much as possible, reducing the pollution of dust to the working environment. When the material is transported along the conveyor belt, the nozzle sprays water on the material on the surface of the conveyor belt, thereby reducing the dust generated during the material transportation process and further reducing the pollution of dust to the working environment;

[0025] 2. When the material enters the discharge hopper, the guide plate acts as a buffer for impurities, thereby slowing down the movement of the material, reducing the impact of the material on the conveyor belt, and reducing the dust generated, further reducing the dust entering the working environment;

[0026] 3. After long-term use, the scraper is prone to adhesion of materials or wear. When removing the scraper, move the moving block along the length direction of the conveyor belt so that the moving block slides along the length direction of the conveyor belt and connects to the moving hole. Move the moving block away from the moving hole and the scraper away from the frame to facilitate cleaning and replacement of the scraper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses a discharging device of an ore crusher. Figure 1 and Figure 2 A discharging device of an ore crusher includes a frame 100 and a discharging hopper 200. The frame 100 is connected to a conveyor belt 300. The conveyor belt 300 is arranged horizontally, and the discharging hopper 200 is arranged vertically. The conveyor belt 300 is arranged below the discharging hopper 200. The top of the discharging hopper 200 is used to communicate with the discharging port of the crusher body.

[0036] Reference Figure 1 and Figure 3 The discharge hopper 200 has a discharge port 210 at its bottom. The length of the discharge hopper 200 is consistent with the length of the conveyor belt 300. The discharge hopper 200 is connected to the frame 100 via a dust cover 110. The dust cover 110 is connected to the frame 100. The length of the dust cover 110 is consistent with the length of the conveyor belt 300. The dust cover 110 is located above the conveyor belt 300. The discharge hopper 200 is connected to the dust cover 110 along one end of the length of the dust cover 110. The discharge port 210 connects the discharge hopper 200 and the dust cover 110. The dust cover 110 has a connection port 120 for material to pass through along its length and away from the end of the discharge hopper 200. The dust cover 110 is added to reduce the entry of dust into the working environment.

[0037] Reference Figure 1 and Figure 3The discharge hopper 200 is connected to a guide plate 220. Two guide plates 220 are provided. The length direction of the guide plates 220 is consistent with the width direction of the discharge hopper 200. The two ends of the guide plates 220 along their length direction are in contact with the inner wall of the corresponding side of the discharge hopper 200. The two guide plates 220 are distributed in sequence along the length direction of the discharge hopper 200. The two guide plates 220 are in contact with each other at one end close to each other, and the side of the guide plate 220 away from the other guide plate 220 is spaced apart from the inner wall of the discharge hopper 200. The guide plates 220 are rotatably connected to the inner wall of the discharge hopper 200 along their width direction and close to each other at one end. The other end of the guide plate 220 is tilted toward the side near the discharge port 210.

[0038] Reference Figure 3 and Figure 4 A support plate 230 is connected to the discharge hopper 200. The length of the support plate 230 is aligned with the width of the discharge hopper 200, and both ends of the support plate 230 are connected to the corresponding inner walls of the discharge hopper 200 along its length. The support plate 230 is positioned between the two guide plates 220. A shock-absorbing assembly 400 is connected to the support plate 230 to reduce the impact of the material on the guide plates 220.

[0039] Reference Figure 3 and Figure 4 The shock-absorbing assembly 400 includes a sliding rod 410 and a first spring 420. The length of the sliding rod 410 is consistent with the vertical direction. The sliding rod 410 is arranged below the guide plate 220. The sliding rod 410 passes through the support plate 230 in the vertical direction and is slidably connected. The bottom end of the sliding rod 410 is connected to a mounting block 411, and the top end of the sliding rod 410 is connected to a buffer block 412. The buffer block 412 is made of rubber and contacts the guide plate 220. The length of the first spring 420 is consistent with the vertical direction. The first spring 420 is sleeved on the sliding rod 410. The top end of the first spring 420 is connected to the bottom of the support plate 230, and the bottom end of the first spring 420 is connected to the top of the mounting block 411. When the guide plate 220 contacts the buffer block 412, the first spring 420 stretches and deforms.

[0040] When the material collides with the guide plate 220, the guide plate 220 rotates due to the impact of the material, thereby causing the guide plate 220 to push the sliding rod 410 to move downward in the vertical direction, and causing the first spring 420 to stretch and deform. The first spring 420 can fully absorb the impact force caused by the falling material and reduce the damage caused by the collision between the guide plate 220 and the material.

[0041] Reference Figure 3The discharge port 210 is circular, with a support rod 240 connected to its bottom end. The length of the support rod 240 is aligned with the radial direction of the discharge port 210. The top of the support rod 240 is rotatably connected to a rotating rod 250. The length of the rotating rod 250 is aligned with the vertical direction. A buffer plate 260 is connected to the circumference of the rotating rod 250. The buffer plate 260 is spirally arranged and is used to guide the material to be discharged onto the surface of the conveyor belt 300. The buffer plate 260 is arranged below the guide plate 220.

[0042] The material moves along the guide plate 220 to the buffer plate 260, and the material moves along the buffer plate 260 and falls onto the surface of the conveyor belt 300. The buffer plate 260 is added to further slow down the movement speed of the material and avoid collisions between materials as much as possible, reduce the generation of dust, and further reduce the entry of dust into the working environment.

The water outlet pipe 600 is located at the end of the dust cover 110 away from the discharge hopper 200. The two ends of the water outlet pipe 600 along its length contact the inner wall of the dust cover 110 on the corresponding side. The water outlet pipe 600 is located above the conveyor belt 300. The bottom of the water outlet pipe 600 is connected to a plurality of nozzles 610. The nozzles 610 are sequentially spaced along the length of the water outlet pipe 600, and the water outlets of the nozzles 610 are arranged toward the conveyor belt 300. The water outlet pipe 600 is connected to the water supply pipe 620, which is used to input water into the water outlet pipe 600. One end of the water supply pipe 620 is connected to the water outlet pipe 600, and the other end of the water supply pipe 620 passes through the dust cover 110. The water supply pipe 620 is connected to a water pump 630, and the water pump 630 is connected to the top of the dust cover 110.

[0044] When the material is being transported, the nozzle 610 sprays water on the material to settle the dust and reduce the dust from entering the working environment.

[0045] Reference Figure 3 The frame 100 is connected to a scraper 130, which is arranged under the conveyor belt 300. The length direction of the scraper 130 is consistent with the width direction of the conveyor belt 300. The scraper 130 is arranged at the end of the conveyor belt 300 away from the feed hopper. The top end of the scraper 130 contacts the bottom of the conveyor belt 300, and the bottom end of the scraper 130 is inclined toward the side close to the feed hopper.

[0046] Reference Figure 3 and Figure 5The scraper 130 is connected to movable blocks 131 on both sides along its length. The length of the movable blocks 131 is aligned with the width of the conveyor belt 300. The frame 100 is provided with two movable holes 140, which are spaced apart along the width of the conveyor belt 300. The length of the movable holes 140 is aligned with the length of the conveyor belt 300, and one end of the movable holes 140 is open. The movable blocks 131 correspond one-to-one with the movable holes 140. The movable blocks 131 pass through the movable holes 140 along their length and are slidably connected to the movable holes 140 along the length of the conveyor belt 300.

[0047] Reference Figure 5 and Figure 6 A locking assembly 500 is connected to the movable hole 140, and the locking assembly 500 is used to lock the locking block 520 in the movable hole 140. A mounting groove 150 is provided on the inner wall at the bottom of the movable hole 140, and the length direction of the mounting groove 150 is consistent with the vertical direction. The locking assembly 500 includes a second spring 510 and a locking block 520. The length direction of the second spring 510 is consistent with the vertical direction. One end of the second spring 510 is connected to the inner wall of the mounting groove 150 along its length, and the other end of the second spring 510 is connected to the bottom of the locking block 520. The locking block 520 is slidably connected to the mounting groove 150 along the vertical direction, and the top of the locking block 520 contacts the inner wall at the top of the movable hole 140. Sliding holes 151 are provided in the mounting groove 150 along the width direction of the conveyor belt 300 and on the side away from the other mounting groove 150. The length direction of the sliding hole 151 is consistent with the vertical direction. A pull block 521 is connected to the locking block 520 along the width of the conveyor belt 300 and away from the other locking block 520. The pull block 521 is connected to the top of the locking block 520 and slides vertically within the sliding hole 151. When the locking block 520 contacts the inner wall of the movable hole 140, the pull block 521 moves away from the sliding hole 151.

[0048] The scraper 130 is added to facilitate cleaning of the conveyor belt 300 and reduce impurities adhering to the surface of the conveyor belt 300. The scraper 130 is detachably connected to the frame 100, so that the scraper 130 is easy to clean and replace.

[0049] The implementation principle of the discharge device of an ore crusher in the embodiment of the present application is as follows: the crushed material enters the discharge hopper 200, and the guide plate 220 blocks the high-speed falling material, thereby slowing down the movement of the material. The material hits the guide plate 220, which drives the guide plate 220 to rotate. The guide plate 220 pushes the sliding rod 410 to move downward in the vertical direction, and causes the first spring 420 to stretch and deform. The first spring 420 can fully absorb the impact force brought by the falling material, and the guide plate 220 guides the guide plate 220 to the discharge hopper 200. The side wall reduces the impact of the material on the buffer plate 260. The material moves along the side wall of the discharge hopper 200 to the buffer plate 260, and moves along the buffer plate 260. The material falls to the surface of the conveyor belt 300 through the discharge port 210, and the conveyor belt 300 drives the material to be transported. At the same time, the water pump 630 inputs water into the water outlet pipe 600, and the water is sprayed to the material through the nozzle 610 to settle the dust, and the dust cover 110 blocks part of the dust from entering the working environment, thereby reducing the dust from entering the working environment and reducing the impact of dust on the working environment.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
