Description

Technical Field

[0001] This utility model relates to the field of vibratory ore discharge equipment, specifically to a vibratory ore discharge machine capable of quantitative material discharge. Background Technology

[0002] A vibrating ore feeder is a type of inertial vibration ore discharge equipment that uses a vibrating motor as the excitation source. It is an ideal device for discharging, feeding, or loading or transporting ores and other materials. Compared with other types of ore feeders, vibrating ore feeders have the following advantages: energy saving, high ore discharge efficiency, uniform ore discharge, and easy control. They are widely used in mining industries such as metallurgy, chemical industry, building materials, and coal mining.

[0003] The utility model patent with authorization announcement number CN214877835U discloses a vibratory ore discharge machine capable of quantitative discharge, including an ore discharge machine and a discharge section; springs are sleeved on both the upper and lower sides of the fixed block on the first support rod; a vibratory motor is installed on the bottom surface of the machine body; a discharge port is opened at the front end of the bottom of the box body, a cavity is opened on the bottom surface of the box body, and a guide groove is opened at the front end of the cavity; a baffle for controlling the discharge of material from the discharge port is slidably installed at the guide groove.

[0004] In the specific implementation of the above-mentioned patent, although it can achieve the function of quantitative material discharge by setting a gate structure, and avoid increasing the load on the vibration motor by not directly contacting the box and the machine body, the gate structure only achieves the discharge of ore by natural material sliding. Therefore, during the material sliding process, the ore may be blocked at the discharge port, which can easily cause the discharge port to be blocked and lead to the interruption of ore discharge.

[0005] The purpose of this utility model is to provide a vibratory ore discharge machine that can quantitatively discharge ore in order to solve the above problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a vibratory ore discharge machine capable of quantitative discharge, including an ore storage box and an ore discharge assembly. The ore storage box and the ore discharge assembly are located at the rear and front, respectively. The discharge direction of the ore storage box and the ore discharge assembly is inclined downward from rear to front along the longitudinal direction, so as to allow the ore to slide down through the ore storage box to the ore discharge assembly and be discharged forward by the ore discharge assembly.

The base is placed flat below the discharge box, and the bottom surfaces of the shock absorbers at the front position are fixedly installed on the top surface of the base, while the bottom surfaces of the shock absorbers at the rear position are raised and fixed to the top surface of the base by pads.

[0011] Preferably, the vibratory motor body is an eccentric vibratory motor, and the shock absorber is a spring-type shock absorber.

[0012] Preferably, the front edge of the ore storage box extends downwards and is fixedly connected to a guide plate, and the front edge of the guide plate is suspended above the rear of the discharge box. The tilt angle of the ore storage box is greater than the tilt angle of the discharge box, and the tilt angle of the guide plate is greater than the tilt angle of the ore storage box.

[0013] Preferably, the material feeding control component includes a U-shaped bracket and a hydraulic cylinder body. The U-shaped bracket is inverted on both sides of the front of the ore storage box, and the bottom sides of the U-shaped bracket are detachably connected to the ore storage box via the disassembly and assembly assembly. The top surface of the U-shaped bracket is vertically fixed to the hydraulic cylinder body. The telescopic push rod at the bottom of the hydraulic cylinder body passes through the top and bottom surfaces of the U-shaped bracket in a sliding fit, and the bottom end is horizontally fixed to a lifting seat via a connecting sleeve. The front part of the bottom of the lifting seat extends vertically downward and is fixed to a baffle plate. The baffle plate is horizontally arranged, and the two sides of the baffle plate are inserted into the front inner side of the ore storage box in a sliding fit.

[0014] Preferably, the bottom rear of the lifting seat has multiple vertically arranged unblocking plates fixedly extending downwards, and the bottom ends of the unblocking plates are all pointed in an inverted triangle shape.

[0015] Preferably, the vertical dimension of the baffle plate is larger than the vertical dimension of the ore storage box, and the inner walls on both sides of the ore storage box are equipped with guide rails for guiding and correcting the lifting and lowering process of the baffle plate, and the sides of the baffle plate are inserted into the corresponding guide rails in a sliding fit manner.

[0016] Preferably, each of the disassembly and assembly components includes a mating seat and a fixing sleeve. The mating seats are fixedly extended vertically downward on both bottom surfaces of the U-shaped bracket, and the outer sides of the two mating seats that are far apart from each other are provided with lateral limit holes. The fixing sleeves are fixedly installed on both sides of the front part of the ore storage box. The top surface of each fixing sleeve is provided with a mating groove, and the mating groove corresponds to the mating seat and slides vertically. The outer end faces of the fixing sleeves on both sides that are far apart from each other are provided with mounting holes on the lateral side. The mounting holes are vertically connected to the corresponding mating grooves, and the mounting holes are coaxially inserted with limit rods in a sliding fit. The ends of the limit rods on both sides that are close to each other are provided with lateral sliding fits to the corresponding limit holes.

[0017] Preferably, the ends of the limiting rods on both sides that are far apart from each other are coaxially fixed with handles, and the portions of the limiting rods located between the corresponding handles and the outer end faces of the fixing sleeves are coaxially fitted with springs with clearance, and the two ends of the springs are respectively fixedly connected to the corresponding handles and the outer end faces of the fixing sleeves.

[0018] Preferably, all the mating seats are rectangular blocks, all the mating grooves are rectangular grooves, all the mating grooves are blind grooves in the vertical direction and are opened from top to bottom, and the bottom end of each mating seat is in close contact with the bottom end of the corresponding mating groove.

[0019] In the above-mentioned vibratory ore discharge machine with quantitative discharge capability, specifically during ore discharge, the ore falls into the ore storage box and slides down from the front opening into the discharge box. The vibratory motor of the discharge box is powered by an external power cable, causing the ore to slide down and be discharged through the front of the discharge box. Since a discharge control component with a discharge unblocking function is assembled at the front of the ore storage box, the size and opening / closing control of the front opening of the ore storage box can be adjusted and controlled by the lifting seat of the discharge control component driving the baffle plate to rise and fall. This facilitates quantitative control of the amount of ore fed into the ore discharge component. Simultaneously, when the front opening of the ore storage box is blocked by ore, the lifting seat drives the unblocking plate to repeatedly rise and fall vertically, and the tip of the unblocking plate at its bottom end... The downward pushing method enables the segmentation and unblocking of congested materials, ensuring timely unblocking to resume ore discharge operations. Because the mating seat and the mating groove of the assembly are vertically slidably engaged, and the limiting rod and the limiting hole are horizontally slidably engaged, the material discharge control component can be detachably assembled at the front of the ore storage box. The assembly method at the rear of the ore storage box is simple and easy to implement, facilitating the quick assembly of the material discharge control component at the front of the ore storage box for quantitative material discharge control and unblocking operations. Furthermore, since the mating seat can slide upwards out of the mating groove simply by pulling the limiting rod out of the limiting hole, the material discharge control component can be detached from the front of the ore storage box. The disassembly method at the rear of the ore storage box is simple and easy to implement, facilitating subsequent maintenance and repair after the material discharge control component is removed from the front of the ore storage box.

[0020] The beneficial effects are as follows: 1. This utility model has a material discharge control component with a material discharge and unblocking function assembled at the front of the ore storage box. Then, by means of the lifting seat of the material discharge control component driving the baffle plate to rise and fall, the size of the front opening of the ore storage box can be adjusted and the opening and closing can be controlled. This makes it easy to quantitatively control the amount of ore fed into the material discharge component. At the same time, when the front opening of the ore storage box is blocked by ore, the lifting seat drives the unblocking plate to rise and fall vertically repeatedly and pushes down the tip of the unblocking plate to achieve the division and unblocking operation of the blocked material, ensuring that the unblocking can be restored in time.

[0021] 2. By using the vertical sliding fit between the mating seat and the mating groove of the disassembly and assembly assembly components and the horizontal sliding fit between the limiting rod and the limiting hole, the material discharge control assembly can be detachably assembled at the front of the ore storage box. The assembly method of the material discharge control assembly at the rear of the ore storage box is simple and easy to implement, which facilitates the quick assembly of the material discharge control assembly at the front of the ore storage box for quantitative control of material discharge and unblocking operations.

[0022] 3. Simply pull the limit rod out of the limit hole to allow the mating seat to slide upward and disengage from the mating groove. This allows the material discharge control component to be removed from the front of the ore storage box. The method of disassembling the material discharge control component at the rear of the ore storage box is simple and easy to implement, which facilitates subsequent maintenance and repair after removing the material discharge control component from the front of the ore storage box.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] See Figures 1-9As shown, this utility model provides a vibratory ore discharge machine capable of quantitative discharge, including an ore storage box 1 and an ore discharge assembly 4. The ore storage box 1 and the ore discharge assembly 4 are located at the rear and front, respectively. The discharge direction of the ore storage box 1 and the ore discharge assembly 4 is inclined downwards from the rear to the front along the longitudinal direction. Preferably, multiple support legs for raising and supporting are vertically fixed around the bottom surface of the ore storage box 1, and the bottom ends of the support legs are flatly fixed with connecting plates for fixing to the ground. The ore is slid down from the ore storage box 1 to the ore discharge assembly 4 and discharged forward by the ore discharge assembly 4. Specifically, the ore discharge assembly 4 includes a discharge box 402, a shock absorber 404, and a base 403. The discharge box 402 is a box with an open top and front, and the discharge direction of the discharge box 402 is inclined downwards from the rear to the front along the longitudinal direction. The material is arranged longitudinally from back to front with an upward tilt. Shock absorbers 404 are installed at the four corners of the bottom surface of the feeding box 402. A vibrating motor body 405 is installed on the bottom surface of the feeding box 402. A base 403 is placed flat below the feeding box 402. The bottom surfaces of the shock absorbers 404 at the front position are fixedly installed on the top surface of the base 403, and the bottom surfaces of the shock absorbers 404 at the rear position are raised and fixed on the top surface of the base 403 by pads 401. The purpose of this arrangement is that after the ore falls into the ore storage box 1, it slides down from the front opening into the feeding box 402. The vibrating motor body 405 of the feeding box 402 is powered on by being electrically connected to an external power supply cable. The vibration of the feeding box 402 by the vibrating motor body 405 causes the ore to slide down and be discharged through the front of the feeding box 402, thereby realizing the ore feeding operation.

[0037] See Figures 1-5As shown, the ore storage box 1 is an open box at the front, back, and top. A material discharge control assembly 5 with a material unblocking function is installed at the front opening of the ore storage box 1. Specifically, the material discharge control assembly 5 includes a U-shaped bracket 502 and a hydraulic cylinder body 501. The U-shaped bracket 502 is inverted on both sides of the front of the ore storage box 1, and both bottom sides of the U-shaped bracket 502 are detachably connected to the ore storage box 1 via a disassembly and assembly assembly 2. The hydraulic cylinder body 501 is vertically fixed to the top surface of the U-shaped bracket 502. The telescopic push rod 503 at the bottom of the hydraulic cylinder body 501 slides through the top and bottom surfaces of the U-shaped bracket 502, and a lifting seat 504 is horizontally fixed to its bottom end via a connecting sleeve 507. A baffle plate 506 extends vertically downward from the front of the bottom of the lifting seat 504 and is horizontally positioned. Furthermore, the two sides of the baffle plate 506 are inserted into the front inner side of the ore storage box 1 in a sliding fit. The bottom rear of the lifting seat 504 extends vertically downward and is fixed with multiple vertically placed unblocking plates 508. The bottom ends of the unblocking plates 508 are all inverted triangular pointed parts 509. The effect of this setting is that by using the lifting seat 504 of the material discharge control component 5 to drive the baffle plate 506 to rise and fall, the size of the front opening of the ore storage box 1 can be adjusted and the opening and closing can be controlled. This facilitates the quantitative control of the amount of ore fed into the ore discharge component 4. At the same time, when the front opening of the ore storage box 1 is blocked by ore, the unblocking plates 508 can be repeatedly raised and lowered vertically by the lifting seat 504 and pushed down by the pointed parts 509 at the bottom of the unblocking plates 508, so as to realize the division and unblocking operation of the blocked material.

[0038] See Figures 1-9As shown, the front sides of the ore storage box 1 are equipped with disassembly and assembly components 2, and the material discharge control component 5 is detachably fixed to the front of the ore storage box 1 through the disassembly and assembly components 2. Specifically, each disassembly and assembly component 2 includes a mating seat 206 and a fixing sleeve 201. The bottom surfaces of both sides of the U-shaped bracket 502 extend vertically downward and are fixed with mating seats 206. The outer sides of the two mating seats 206 that are far apart from each other are opened with limit holes 208 in the horizontal direction. The front sides of the ore storage box 1 are fixedly installed with fixing sleeves 201. The top surfaces of the fixing sleeves 201 are vertically opened with mating grooves 205, and the mating grooves 205 correspond one-to-one with the mating seats 206 and slide vertically. The outer ends of the fixing sleeves 201 on both sides are opened with mounting holes 204 in the horizontal direction. The mounting holes 204 are vertically connected to the corresponding mating grooves 205, and the mounting holes 204 are coaxially inserted with limit rods 207 in a sliding fit. The limit rods 207 on both sides are close to each other. The ends of the limiting rods 207 at the near end are all laterally slidably engaged with the corresponding limiting holes 208. The ends of the limiting rods 207 at the two sides are coaxially fixed with handles 202. The part of the limiting rod 207 located between the corresponding handle 202 and the outer end face of the fixing sleeve 201 is coaxially fitted with a spring 203. The two ends of the spring 203 are respectively fixedly connected to the corresponding handle 202 and the outer end face of the fixing sleeve 201. The reason for this arrangement is that by vertically sliding the mating seat 206 of the disassembly and assembly assembly 2 with the mating groove 205 and laterally sliding the limiting rod 207 with the limiting hole 208, the material discharge control assembly 5 can be detachably assembled at the front of the ore storage box 1. At the same time, by simply pulling the limiting rod 207 out of the limiting hole 208, the mating seat 206 can slide upward and disengage from the mating groove 205. In this way, the material discharge control assembly 5 can be detached from the front of the ore storage box 1. The assembly and disassembly of the material discharge control assembly 5 at the rear of the ore storage box 1 is simple and easy to implement.

[0039] See Figures 1-9 As shown, the following optimizations have been made to this application. Specifically, the vibration motor body 405 is an eccentric vibration motor, and the shock absorber 404 is a spring 203 type shock absorber 404, so that the setting of the vibration motor body 405 and the shock absorber 404 can meet the usage requirements. Optionally, the front edge of the ore storage box 1 extends downward and is fixedly connected to a guide plate 3, and the front edge of the guide plate 3 is suspended above the rear of the discharge box 402. The tilt angle of the ore storage box 1 is greater than the tilt angle of the discharge box 402, and the tilt angle of the guide plate 3 is greater than the tilt angle of the ore storage box 1. This setting facilitates the guidance of the ore into the discharge box 402 by the guide plate 3, and also ensures that the tilt angles of the ore storage box 1, the discharge box 402, and the guide plate 3 meet the actual usage requirements.

[0040] See Figures 1-9As shown, the vertical dimension of the baffle plate 506 is larger than the vertical dimension of the ore storage box 1. Both inner walls of the ore storage box 1 are equipped with guide rails 505 for guiding and correcting the lifting and lowering process of the baffle plate 506. The sides of the baffle plate 506 are inserted into the corresponding guide rails 505 in a sliding fit. With this setting, the size of the baffle plate 506 can completely block the front opening of the ore storage box 1. At the same time, the guide rails 505 are used to guide and correct the lifting and lowering process of the baffle plate 506. Alternatively, the mating seats 206 are all rectangular blocks, and the mating grooves 205 are all rectangular grooves. The mating grooves 205 are all blind grooves in the vertical direction and are opened from top to bottom. The bottom end of each mating seat 206 is in close contact with the bottom end of the corresponding mating groove 205. This arrangement firstly facilitates good positioning and guiding design when the mating seat 206 slides along the mating groove 205. At the same time, during the process of the mating seat 206 sliding along the mating groove 205, when the limiting hole 208 slides with the mating seat 206 to be coaxial with the limiting rod 207, the bottom end of each mating seat 206 is in close contact with the bottom end of the corresponding mating groove 205, which provides a clear indication.

[0041] Using the above structure, specifically in the process of discharging ore, after the ore falls into the ore storage box 1, it slides down from the front opening into the discharge box 402. The vibrating motor body 405 of the discharge box 402 is powered on via an external power cable. The vibrating motor body 405 excites the discharge box 402, causing the ore to slide down and be discharged through the front of the discharge box 402, thus realizing the ore discharge operation. Because a lower... The material discharge control component 5, which has a material unblocking function, can adjust the size and control the opening of the front opening of the ore storage box 1 by means of the lifting seat 504 of the material discharge control component 5 driving the baffle plate 506 to rise and fall. This facilitates the quantitative control of the amount of ore fed into the material discharge component 4. At the same time, when the front opening of the ore storage box 1 is blocked by ore, the lifting seat 504 drives the unblocking plate 508 to rise and fall vertically repeatedly, and the tip 509 at the bottom of the unblocking plate 508 lowers. The pushing method enables the segmentation and unblocking of congested materials, ensuring timely unblocking to resume ore discharge operations. Furthermore, the material discharge control component 5 can be detachably assembled at the front of the ore storage box 1 via the vertical sliding engagement of the mating seat 206 and the mating groove 205, and the lateral sliding engagement of the limiting rod 207 and the limiting hole 208. The assembly of the material discharge control component 5 at the rear of the ore storage box 1 is simple and easy to implement, thus facilitating the material discharge control... Component 5 is quickly assembled at the front of the ore storage box 1 for quantitative control of material discharge and unblocking of blockages. At the same time, since only the limit rod 207 needs to be pulled out of the limit hole 208 to allow the mating seat 206 to slide upward and disengage from the mating groove 205, the material discharge control component 5 can be removed from the front of the ore storage box 1. The method of disassembling the material discharge control component 5 at the rear of the ore storage box 1 is simple and easy to achieve, which facilitates subsequent maintenance and repair after the material discharge control component 5 is removed from the front of the ore storage box 1.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
