Specific implementation manners

[0023] The following further describes the present utility model in detail in conjunction with the accompanying drawings and specific implementation manners, but does not limit the protection scope and application scope of the present utility model.

[0024] Embodiment: An ore sample preparation crusher, as Figures 1-4As shown in the figure, it includes supporting feet 1, a cylinder body 2, a sealing plate 201, a motor 3, a crushing assembly 301, a dust-proof box 5, a multi-stage screening frame 6, a screen 601 and a discharging assembly. Supporting feet 1 are symmetrically arranged on both sides of the cylinder body 2. A sealing plate 201 for plugging the opening is detachably arranged on the front opening side of the cylinder body 2. A crushing assembly 301 is rotatably arranged inside the cylinder body 2. The crushing assembly 301 includes a hammer disc installed on the inner wall of the cylinder body 2, a transmission shaft for connecting with a power element, and hammers hinged on the transmission shaft. The crushing assembly 301 is used for crushing the ore sample inside the cylinder body 2. The transmission shaft on the crushing assembly 301 is connected to the output shaft of the motor 3 installed on the back of the cylinder body 2 through a coupling. A discharging assembly is arranged at the lower part of the cylinder body 2. The dust-proof box 5 is arranged below the cylinder body 2. The top of the dust-proof box 5 is provided with an arc-shaped opening. The material inside the cylinder body 2 is discharged into the dust-proof box 5 through the discharging assembly. The top of the dust-proof box 5 is in contact and cooperation with the cylinder body 2. A plastic sealing ring 8 is arranged at the contact part between the top of the dust-proof box 5 and the outer wall of the cylinder body 2. Arranging the plastic sealing ring 8 between the dust-proof box 5 and the cylinder body 2 can prevent the dust generated during the discharging of the cylinder body 2 from flying outside the dust-proof box 5 through the gap between the dust-proof box 5 and the cylinder body 2. Convex blocks 501 are symmetrically arranged on both sides of the dust-proof box 5. When the cylinder body 2 is placed on the dust-proof box 5, the convex blocks 501 are used to provide support for the supporting feet 1. A multi-stage screening frame 6 is movably arranged inside the dust-proof box 5. Three layers of screens 601 are arranged inside the multi-stage screening frame 6. The mesh diameters of the screens 601 inside the multi-stage screening frame 6 gradually become smaller from top to bottom, so as to realize multi-level screening operation on the ore sample.

[0025] As Figure 2 and Figure 3 shown, the discharging assembly includes an arc-shaped baffle 202, a rotating shaft 203, an electric slide rail 1 4 and a clamping block 401. An arc-shaped discharging port is opened at the bottom of the cylinder body 2. An arc-shaped baffle 202 for plugging the discharging port is rotatably installed on the cylinder body 2 through the rotating shaft 203. An electric slide rail 1 4 is arranged on the cylinder body 2. A clamping block 401 is slidably connected to the electric slide rail 1 4. The clamping block 401 is used to limit the arc-shaped baffle 202 so that the arc-shaped baffle 202 plugs the discharging port on the cylinder body 2. When the clamping block 401 moves along the electric slide rail 1 4 towards the two transverse ends of the cylinder body 2, the clamping block 401 gradually moves away from the arc-shaped baffle 202, thereby releasing the limiting effect on the arc-shaped baffle 202. Under the action of gravity, the arc-shaped baffle 202 rotates downward by 90 degrees with the rotating shaft 203 as the center, and the material inside the cylinder body 2 is discharged downward through the discharging port; conversely, after rotating the arc-shaped baffle 202 back to its original position, the two clamping blocks 401 are driven to approach each other through the electric slide rail 1 4, thereby limiting the arc-shaped baffle 202.

[0026] As Figure 5 and Figure 6As shown in the figure, it also includes a wedge block 9, a guide rod 901, a spring 902 and an F plate 10. F plates 10 are provided on both side walls of the dust-proof box 5. The F plates 10 are arranged above the bumps 501. Guide rods 901 are provided on the F plates 10. Two symmetrical wedge blocks 9 are slidably connected to the guide rods 901. The wedge blocks 9 slide through the F plates 10 and are in snap-fit with the wedge grooves formed on the support feet 1. A spring 902 is provided on the guide rod 901. The spring 902 is a compression spring. The arrangement of the spring 902 keeps the wedge blocks 9 in a state of being snapped into the wedge grooves on the support feet 1.

[0027] During use, lift the sealing plate 201 from the cylinder body 2, place the ore sample to be crushed into the cylinder body 2 and reset the sealing plate 201. Subsequently, place the cylinder body 2 on the dust-proof box 5, place the support feet 1 on the bumps 501, and fix the cylinder body 2 on the dust-proof box 5 by snapping the wedge blocks 9 into the wedge grooves of the support feet 1. Drive the crushing assembly 301 to rotate through the motor 3, and the crushing assembly 301 crushes the ore sample in the cylinder body 2. Since the cylinder body 2 is airtight, the dust generated during crushing is inside the cylinder body 2, thus avoiding the dust from flying in the laboratory and protecting the experimental environment. After the ore sample is crushed, drive the block 401 to move horizontally along the electric slide rail 1 through the electric slide rail 1. The block 401 moves in a direction away from the arc-shaped baffle 202, releasing the limiting effect of the block 401 on the arc-shaped baffle 202. Under the action of gravity, the arc-shaped baffle 202 rotates downward by 90 degrees with the rotation axis 203 as the center, and the crushed ore in the cylinder body 2 is unloaded downward through the discharge port of the cylinder body 2 into the multi-stage screening frame 6 in the dust-proof box 5. The crushed ore falls onto the screen 601, and the multi-layer screen 601 screens the ore in layers, thus screening the crushed ore according to the particle size. Since the dust-proof box 5 is in a sealed state, the dust generated during the ore unloading and screening operation is blocked inside the dust-proof box 5, thus realizing a dust-free screening operation.

[0028] As Figure 1 and Figure 6 As shown in the figure, it also includes a connecting plate 701 and a limiting block 702. A side plate 7 for closing the front opening of the dust-proof box 5 is slidably connected to the front opening side of the dust-proof box 5. A connecting plate 701 is provided on the side plate 7. The connecting plate 701 slides through the limiting block 702 installed on the outer wall of the dust-proof box 5. The limiting block 702 is used to limit the displacement distance of the connecting plate 701.

[0029] As Figure 4As shown in the figure, it further includes a scraper 11 and an electric slide rail two 1101. Four electric slide rails two 1101 are provided on the inner wall of the multi-stage screening frame 6. The electric slide rail two 1101 is arranged above the screen 601. A scraper 11 is slidably connected to the electric slide rail two 1101. One end of the scraper 11 away from the electric slide rail two 1101 is slidably matched with a chute opened on the inner wall of the multi-stage screening frame 6. The scraper 11 is slidably matched with the screen 601 on the multi-stage screening frame 6. The electric slide rail two 1101 drives the scraper 11 to move horizontally. The scraper 11 scrapes the sample on the screen 601 in the multi-stage screening frame 6 forward, so as to collect the sample screened by the screen 601 in the multi-stage screening frame 6.

[0030] After the crushed ore completes the screening operation and stands still for a period of time, pull the connecting plate 701 to the right. The connecting plate 701 drives the side plate 7 to slide to the right. At this time, the electric slide rail two 1101 drives the scraper 11 to move forward. The scraper 11 scrapes the ore sample on the screen 601 to the front. At this time, the ore sample on the screen 601 can be collected through the notch at the front of the dust-proof box 5; the wedge block 9 can also be pulled in the direction away from the support foot 1, so that the wedge block 9 is away from the wedge groove on the support foot 1, and the limiting effect of the wedge block 9 on the support foot 1 is released. At this time, the cylinder body 2 can be taken off from the dust-proof box 5. Thus, the inner wall of the cylinder body 2 is cleaned, and the arc-shaped baffle 202 is rotated back to its original position. The electric slide rail one 4 drives the clamping block 401 to move horizontally to limit the arc-shaped baffle 202, so that the arc-shaped baffle 202 keeps blocking the discharge port of the cylinder body 2; the multi-stage screening frame 6 is taken out of the dust-proof box 5 and the multi-stage screening frame 6 and the dust-proof box 5 are thoroughly cleaned, so as to ensure the accuracy of the sample analysis result.

However, the present invention 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 gist of the present invention.
