Description

Technical Field

[0001] This utility model relates to the field of crushing technology, and in particular to a discharge port angle adjustment device for a mining crusher. Background Technology

[0002] In the field of mining and ore processing, mining crushers are one of the most important core equipment. They are responsible for crushing large pieces of ore into smaller pieces that meet the requirements of subsequent processing. After the crusher finishes its work, the crushed ore needs to be discharged smoothly through the discharge port so that it can enter the subsequent processing stages such as conveying and screening.

[0003] Traditional mining crushers typically use a single inclined guide plate at the discharge port. This guide plate has a simple structure, usually consisting of a flat metal plate installed at a fixed angle at the discharge port. Its original design purpose was to guide the crushed ore smoothly down to downstream equipment. However, due to the uneven particle size and high discharge speed of the ore during the crushing process, when the ore slides down from the crusher discharge port through the single guide plate, it will hit the downstream equipment corresponding to the end of the guide plate with a large impact force. Taking the conveyor belt as an example, the rubber layer on the surface of the conveyor belt is easily damaged and torn due to long-term exposure to the high-speed impact of the ore, which greatly shortens the service life of the conveyor belt. Frequent replacement of the conveyor belt not only increases equipment maintenance costs but also causes production line shutdowns, affects production progress, and causes unnecessary economic losses. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a discharge port angle adjustment device for a mining crusher. This device can solve the problem that, due to the uneven particle size and high discharge speed of the ore during the crushing process, when these ores slide down from the crusher discharge port through a single guide plate, they will hit the downstream equipment corresponding to the end of the guide plate with a large impact force. Taking the conveyor belt as an example, the rubber layer on the surface of the conveyor belt is easily damaged and torn due to long-term high-speed impact from the ore, which greatly shortens the service life of the conveyor belt. Frequent replacement of the conveyor belt not only increases the equipment maintenance cost, but also causes the production line to stop, affects the production progress, and causes unnecessary economic losses.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a discharge port angle adjustment device for a mining crusher, comprising a discharge box and a discharge auxiliary box, wherein a baffle assembly is provided inside the discharge box; The baffle assembly includes a fixed frame, two baffle components and four fixed plates. Both baffle components are inclined baffles. The four fixed plates are fixedly installed on the left and right outer walls of the baffle components. The left and right outer walls of the fixed frame are each fixedly connected with two magnetic positioning grooves. The left and right inner walls of the discharge box are each provided with positioning grooves. The front and rear outer walls of the discharge box are each provided with grooves. The outer wall of the fixed frame is slidably connected to the inside of the discharge box. The front and rear outer walls of the discharge auxiliary box are fixedly connected with protrusions. The inner walls of the two grooves are each provided with two first fixing bolt slots. The upper surfaces of the two protrusions are each threaded with first fixing bolts. The left and right inner walls of the fixed frame are each provided with eight second fixing bolt slots. The outer walls of the four fixed plates are each threaded with second fixing bolts. The two baffles are installed inside the fixed frame and used in conjunction with each other through the second fixing bolts and the corresponding second fixing bolt slots.

[0006] Preferably, the outer walls of the four magnetic positioning grooves are slidably connected to the interior of the corresponding positioning groove.

[0011] Preferably, the lower discharge port of the discharge box is opposite to the upper inlet of the discharge auxiliary box.

[0012] Preferably, a vibration motor is bolted to the left side of the discharge box.

[0013] Preferably, when both of the baffles are grid-type baffles, the two grid-type baffles are arranged at an angle inside the fixed frame and used in conjunction.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The discharge port angle adjustment device of this mining crusher uses two inclined baffles in the baffle assembly. During the ore's fall, it collides with the baffles multiple times, changing the ore's flow direction and speed to achieve a deceleration effect.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Example 1: Reference Figure 1-4 Conventional ore feeding foundation implementation example (inclined baffle plate + magnetic positioning) Suitable for processing ores of conventional hardness such as granite and limestone, this device utilizes inclined baffles and magnetic positioning to provide basic auxiliary feeding functionality. The inclined baffles, made of ordinary carbon steel, are installed at a 45° angle within a fixed frame, guiding the ore to slide down using gravity. The fixed frame is quickly aligned with the magnetic seat on the inner wall of the discharge box via magnetic positioning grooves. The four fixed plates are secured to the baffles with second fixing bolts. During normal crushing and discharge, the inclined baffles change the ore flow direction to prevent accumulation. Magnetic positioning ensures stable installation and easy disassembly, making it suitable for daily production in small and medium-sized mines.

[0022] Example 2: Reference Figure 5 Precision material cutting and grading example (grid-type baffle) For mineral processing operations with strict requirements on discharge particle size, a grid-type baffle plate and angle fine-adjustment structure are adopted to achieve precise material feeding. The baffle plate is a grid type, which screens large materials and controls the particle size of fine materials to ensure that the discharge particle size meets the process standards.

[0023] Furthermore, when using this device, during the operation of the mining crusher, the crushed ore enters the discharge box 1 from the crusher. At this time, the vibrating motor 3 starts and generates vibration, which is transmitted to the inside of the discharge box 1. On the one hand, this promotes smoother flow of the ore and avoids blockage caused by ore accumulation and agglomeration. On the other hand, the vibration helps to disperse the ore on the baffle assembly. After the ore enters the discharge box 1, it first contacts the internal baffle assembly. Since the two baffles 12 are arranged at an angle, the ore will collide with the baffles 12 multiple times during its fall. During the collision, the speed of the ore is reduced and the material flow is dispersed. At the same time, the four fixing plates 10 cooperate with the second fixing bolts 11 and the second fixing bolt grooves 14 to ensure that the baffles 12 are firmly installed in the fixing frame 13 and can withstand the impact of the ore. Then, the fixing frame 13 is installed by the magnetic positioning slide 5 cooperating with the positioning slide 6 on the inner wall of the discharge box 1. The adsorption effect of the magnetic block and the magnetic seat ensures that the fixing frame 13 is in the discharge box 1. The internal stability is ensured to prevent displacement under the impact of ore and the vibration of the vibrating motor 3. If the position of the baffle assembly needs to be adjusted, the sliding characteristics of the magnetic positioning groove 5 and the positioning groove 6 can be used to easily move and reposition the fixed frame 13. Then, the ore guided by the baffle assembly flows out from the discharge port at the lower end of the discharge box 1 and enters the discharge auxiliary box 2. The discharge box 1 and the discharge auxiliary box 2 are secured by the cooperation of the protrusion 9, the groove 8, the first fixing bolt 7 and the first fixing bolt groove 15. The connection is now secure, ensuring that the ore can flow smoothly and without leakage from the discharge box 1 into the discharge auxiliary box 2. Then, when the two baffles 12 are grid-type baffles 16, the grid structure performs preliminary screening of the ore during the flow guidance process. Smaller ore particles fall through the grid gaps, while larger ore particles flow along the grid-type baffles 16, achieving preliminary separation of ore particles of different sizes. This meets the needs of some working conditions that require preliminary screening of ore particle size, reduces the pressure on subsequent screening equipment, and improves overall production efficiency.

[0024] By having two baffles 12 arranged at an angle in the baffle assembly, the ore will collide with the baffles 12 multiple times during its fall. By changing the flow direction and speed of the ore, a deceleration effect is achieved. The ore no longer directly hits downstream equipment, such as the conveyor belt, with a large impact force. This greatly reduces the risk of damage and tearing of the rubber layer on the surface of the conveyor belt, significantly extends the service life of the conveyor belt and other downstream equipment, reduces the frequency of equipment maintenance, lowers equipment maintenance costs, avoids production line downtime caused by frequent equipment replacement, ensures the continuity of production progress, and reduces unnecessary economic losses.

[0025] Structural Description: (I) Overall Frame Structure This device mainly consists of a discharge box 1 and a discharge auxiliary box 2 forming an overall frame. The discharge box 1 is the core area for ore discharge. Elastic bolts 4 are installed at the four corners of its lower end. By cooperating with the slots opened at the four corners of the upper end of the discharge auxiliary box 2, the discharge box 1 and the discharge auxiliary box 2 are installed and fixed. The discharge port at the lower end of the discharge box 1 is opposite to the inlet at the upper end of the discharge auxiliary box 2, ensuring that the ore can flow smoothly from the discharge box 1 into the discharge auxiliary box 2, completing the discharge process connection. In addition, a vibration motor 3 is installed on the left side of the discharge box 1 by bolts to provide auxiliary power for the operation of the device.

[0026] (II) Baffle assembly structure The baffle assembly is a key structure of the device, installed inside the discharge box 1, and includes a fixed frame 13, two baffles 12 and four fixed plates 10.

[0027] Baffle 12: Both baffles 12 are inclined baffles, arranged at an angle. Their function is to change the flow direction and speed of the ore and guide the ore. By setting them at an angle, the ore is blocked and turned multiple times during its fall, thereby achieving the effect of slowing down and dispersing the material flow.

[0028] Fixed plates 10: Four fixed plates 10 are fixedly installed on the left and right outer walls of the baffle 12 to fix and support the baffle 12, enhance its structural stability, and prevent displacement or deformation under the impact of ore.

[0029] Fixed frame 13: Two magnetic positioning slides 5 are fixedly connected to its left and right outer walls, and eight second fixing bolt slots 14 are opened on its left and right inner walls. The magnetic positioning slides 5 cooperate with the positioning slides 6 opened on the left and right inner walls of the discharge box 1 to realize the sliding installation of the fixed frame 13 in the discharge box 1. At the same time, the magnetic blocks installed on the magnetic positioning slides 5 cooperate with the magnetic seats installed inside the positioning slides 6 to enhance the stability of the fixed frame 13 installation and prevent it from shaking during operation. The second fixing bolt slots 14 cooperate with the second fixing bolts 11 threaded on the fixed plate 10 to install and fix the two flow deflectors 12 inside the fixed frame 13.

[0030] (III) Connection and Positioning Structure Connection between discharge box 1 and discharge auxiliary box 2: The front and rear outer walls of discharge auxiliary box 2 are fixedly connected with protrusions 9, and the front and rear outer walls of discharge box 1 are provided with grooves 8. The outer walls of the two protrusions 9 are slidably connected to the interior of the corresponding grooves 8. At the same time, the inner walls of the two grooves 8 are provided with two first fixing bolt slots 15. The upper surfaces of the two protrusions 9 are threaded with first fixing bolts 7. The ends of the four first fixing bolts 7 near the first fixing bolt slots 15 are threaded into the interior of the grooves 8 and are respectively threaded to the interior of the corresponding first fixing bolt slots 15. This structural design realizes a stable connection between discharge box 1 and discharge auxiliary box 2, which is convenient for disassembly and installation.

[0031] Installation and positioning of fixed frame 13: Through the sliding cooperation of magnetic positioning slide 5 and positioning slide 6, and the adsorption effect of magnetic block and magnetic seat, fixed frame 13 can slide and be precisely positioned inside discharge box 1. When it is necessary to adjust the position of baffle assembly or perform maintenance, fixed frame 13 can be easily removed from discharge box 1.

[0032] Grid-type baffle 16: When both baffles 12 are grid-type baffles 16, the two grid-type baffles 16 are arranged at an inclination and used in conjunction inside the fixed frame 13. The grid structure can perform preliminary screening of ore while guiding the flow, allowing smaller ore particles to fall through the grid gaps, while larger ore particles continue to flow along the grid-type baffle 16, thus achieving preliminary separation of ore particles of different sizes.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
