Description

Technical Field

[0001] The utility model belongs to the technical field of granite screening, and particularly relates to a granite gravel shaking table type automatic ore dressing equipment. Background Art

[0002] Granite is a common igneous rock, and its main components include quartz, feldspar, and a small amount of minerals such as biotite and hornblende. It is usually formed by the cooling and solidification of magma deep in the earth's crust, has a granular structure, and is characterized by hard texture, wear resistance, and weather resistance. At present, when granite gravel is beneficiated, special granite gravel shaking table type automatic ore dressing equipment is usually used;

[0003] A granite gravel shaking table type automatic ore dressing equipment with the authorization announcement number of CN 216705114 U includes a support frame. The four ends of the bottom surface of the support frame are connected to support rods, and shock-absorbing devices are connected to the four support rods. The shock-absorbing devices are connected to the shaking table; the bottom surface of the shaking table is connected to a vibration motor. In this granite gravel shaking table type automatic ore dressing equipment, during the horizontal rotation of the shaking table, the inner rod and the outer sleeve rotate around the rotating shaft, driving the inner rod to stretch and contract in the outer sleeve, and the second spring deforms to absorb the horizontal vibration kinetic energy. The mixture of ore and water will not generate dust. During the vibration of the ore, it continuously moves. When passing through the slot holes, the qualified particles fall into the slot holes, and the unqualified ones continue to vibrate and move to the solid position at the edge, completing the automatic separation of ore dressing. By setting horizontal and vertical shock absorption, the damage to the equipment during vibration is reduced;

[0004] Although it can reduce the damage to the equipment during vibration, there are still some problems in daily operations. The slope of the shaking table is fixed and not easy to adjust, which restricts the beneficiation efficiency and flexibility, and limits the application range of granite gravel beneficiation. Summary of the Utility Model

[0005] In view of this, the utility model provides a granite gravel shaking table type automatic ore dressing equipment, which can quickly change the inclination angle of the bed surface of the bed body during the beneficiation operation through an inclination angle adjustment mechanism, significantly enhances the beneficiation efficiency and flexibility, expands the application range of granite gravel beneficiation, and realizes the effective separation and treatment of ore.

[0006] To solve the above technical problems, the utility model provides a granite gravel shaking table type automatic ore dressing equipment, which includes a bed body, a vibration mechanism, and an inclination angle adjustment mechanism arranged at the lower end of the vibration mechanism. The inclination angle adjustment mechanism includes a base arranged at the lower end of the vibration mechanism. The middle part of the right surface of the base is provided with longitudinally symmetrically distributed mounting blocks. A worm is rotatably connected between the rotating holes arranged in the middle of the two mounting blocks. The right end of the vibration mechanism is provided with a worm gear, and the worm gear is meshed and connected with the worm. The rear end of the right surface of the base is also provided with a driving member for driving the worm to rotate.

[0007] The driving member includes a motor disposed at the rear end of the right surface of the base, and the front end of the output shaft of the motor is fixedly connected to the rear end of the worm.

[0008] The inclination adjustment mechanism further includes arc-shaped grooves respectively and symmetrically arranged longitudinally on the left and right wall surfaces of the base. A plurality of convex columns are provided at the lower end of the vibration mechanism, and the convex columns are respectively slidably connected to the adjacent convex columns on the same side.

[0009] The vibration mechanism includes fixing plates symmetrically arranged transversely on the lower surface of the bed body. Between the two fixing plates, there are fixing rods symmetrically distributed longitudinally. A connecting plate is slidably connected between the two fixing rods. The left and right sides of the lower end of the connecting plate are respectively rotatably connected to the corresponding rotary holes provided at the upper ends of the left and right sides of the base. The worm gear is fixedly connected to the right end of the connecting plate, and the convex columns are respectively fixedly connected to the front and rear ends of the left and right surfaces of the connecting plate. A vibration motor is provided in the middle of the lower surface of the bed body.

[0010] The vibration mechanism further includes springs respectively and symmetrically arranged longitudinally between the left and right surfaces of the connecting plate and the inner wall surfaces of the adjacent fixing plates on the same side. The left and right ends of the fixing rods are respectively located inside the adjacent springs on the same side.

[0012] The center of the circle where the arc-shaped groove is located coincides with the rotation axis of the connecting plate.

[0013] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0014] 1. During the ore dressing operation of granite gravel, relevant staff adjust the operation of the motor through an external controller according to the actual separation effect. The rotation of the output shaft of the motor drives the worm to rotate synchronously. When the worm rotates, it drives the connecting plate and its affiliated mechanisms to rotate synchronously through the meshing worm gear, thereby quickly changing the inclination angle of the bed surface of the bed body, significantly enhancing the ore dressing efficiency and flexibility, expanding the application range of granite gravel ore dressing, and realizing the effective separation and treatment of ores.

[0015] 2. Relevant staff adjust the operation of the vibration motor through an external controller. The vibration motor generates a vibration source, and with the auxiliary action of the spring force, the bed body and the fixing plate vibrate left and right along the fixing rods. Then, the granite gravel to be screened is evenly fed onto the bed body. With the reciprocating vibration of the bed body, the granite gravel makes continuous inclined plane sliding and jumping movements on the bed body. Due to the different movement trajectories of granite gravel with different particle sizes and densities under the action of vibration and the bed body, the lighter or smaller particles will gradually move towards the high end, while the heavier or larger particles will move towards the low end, thereby realizing the automatic ore dressing of granite gravel.

[0016] 3. The arc-shaped groove and convex post design ensure the stability of the connecting plate and its attached mechanism during rotation. BRIEF DESCRIPTION OF THE DRAWINGS

Figures 1-4 As shown in FIG.

[0023] As Figures 1-4 shown:

[0024] This embodiment provides an automatic ore dressing equipment of a granite gravel shaking table type, including a bed body 100, a vibration mechanism, and an inclination angle adjusting mechanism arranged at the lower end of the vibration mechanism. The inclination angle adjusting mechanism includes a base 300 arranged at the lower end of the vibration mechanism. A longitudinally symmetrically distributed mounting block 301 is provided in the middle of the right surface of the base 300. A worm 302 is rotatably connected between the rotation holes provided in the middle of the two mounting blocks 301. A worm gear 303 is provided at the right end of the vibration mechanism. The worm gear 303 is meshed and connected with the worm 302. A driving member for driving the worm 302 to rotate is further provided at the rear end of the right surface of the base 300.

[0025] As Figures 1-3As shown, the driving member includes a motor 304 disposed at the rear end of the right surface of the base 300. The front end of the output shaft of the motor 304 is fixedly connected to the rear end of the worm 302. The motor 304 is electrically connected to an external controller.

[0026] As Figures 2-4 shown, the inclination adjustment mechanism further includes arc-shaped grooves 305 longitudinally and symmetrically disposed on the left and right wall surfaces of the base 300 respectively. A plurality of convex columns 306 are provided at the lower end of the vibration mechanism. The convex columns 306 are respectively slidably connected to the adjacent convex columns 306 on the same side.

[0027] As Figures 1-4 shown, the vibration mechanism includes fixing plates 200 horizontally and symmetrically disposed on the lower surface of the bed body 100. Longitudinally and symmetrically distributed fixing rods 201 are provided between the two fixing plates 200. A connecting plate 202 is slidably connected between the two fixing rods 201. The left and right sides of the lower end of the connecting plate 202 are respectively rotatably connected to the corresponding rotation holes provided at the upper ends of the left and right sides of the base 300. The worm gear 303 is fixedly connected to the right end of the connecting plate 202. The convex columns 306 are respectively fixedly connected to the front and rear ends of the left and right surfaces of the connecting plate 202. A vibration motor 203 is provided in the middle of the lower surface of the bed body 100. The vibration motor 203 is electrically connected to an external controller.

[0028] As Figures 1-2 shown, the vibration mechanism further includes springs 204 respectively longitudinally and symmetrically disposed between the left and right surfaces of the connecting plate 202 and the inner wall surfaces of the adjacent fixing plates 200 on the same side. The left and right ends of the fixing rods 201 are respectively located inside the adjacent springs 204 on the same side.

[0029] As Figures 1-4 shown, the center of the circle where the arc-shaped groove 305 is located coincides with the rotation axis of the connecting plate 202.

[0030] The working principle of a granite gravel shaking table type automatic ore dressing equipment provided by the present utility model is as follows: During the ore dressing operation of granite gravel, relevant staff regulate the operation of the motor 304 through an external controller according to the actual separation effect. The output shaft of the motor 304 rotates to drive the worm 302 to rotate synchronously. When the worm 302 rotates, it drives the connecting plate 202 and its attached mechanism to rotate synchronously through the engaged worm gear 303, thereby quickly changing the inclination angle of the bed surface of the bed body 100, significantly enhancing the ore dressing efficiency and flexibility, expanding the application range of granite gravel ore dressing, realizing the effective separation and treatment of ores. The design of the arc-shaped groove 305 and the convex column 306 ensures the stability of the connecting plate 202 and its attached mechanism during rotation. Then, relevant staff regulate the operation of the vibration motor 203 through an external controller. The vibration motor 203 generates a vibration source, and with the auxiliary action of the elastic force of the spring 204, the bed body 100 and the fixed plate 200 vibrate left and right along the fixed rod 201. Then, the granite gravel to be screened is evenly fed onto the bed body 100. With the reciprocating vibration of the bed body 100, the granite gravel makes continuous inclined plane sliding and jumping movements on the bed body 100. Due to the different particle sizes and densities of the granite gravel, under the action of vibration and the bed body 100, their movement trajectories are different. Lighter or smaller particles will gradually move towards the high end, while heavier or larger particles will move towards the low end, thereby realizing the automatic ore dressing of granite gravel.

[0031] As Figure 1 shown, a protective cover 400 is provided on the right surface of the base 300. The mounting block 301, the worm 302, and the worm gear 303 are all located inside the protective cover 400. A through hole adapted to the output shaft of the motor 304 is provided at the lower end of the rear surface of the protective cover 400. The protective cover 400 ensures the safe isolation of the rotating components.

[0032] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
