[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0043] The following is combined with Figure 1-4 The coal sample preparation and cutting device according to the embodiment of the utility model is described.

[0044] The coal sample preparation and cutting device of the embodiment of the utility model comprises a support 1, a material dividing component 2, a material feeding component 3 and a shaping and cutting component 4.

[0045] like Figure 1As shown, the dividing assembly 2 is arranged on the bracket 1, and the dividing assembly 2 includes a dividing barrel 201 with upper and lower openings and a bottom plate 202 arranged at the bottom of the dividing barrel 201 to seal the dividing barrel 201, and the inside of the dividing barrel 201 is used to accommodate the coal to be divided.

[0046] like Figure 1 As shown, the feeding assembly 3 is arranged on the bracket 1 , and the feeding assembly 3 is arranged above the material dividing assembly 2 , and the feeding assembly 3 is used to add coal into the material dividing assembly 2 .

[0047] like Figure 1 As shown, the shaping and slitting assembly 4 is arranged on the bracket 1, and the shaping and slitting assembly 4 is located between the dividing assembly 2 and the feeding assembly 3 in the up and down directions. The shaping and slitting assembly 4 includes a slide rail 401 extending in the horizontal direction and a shaping assembly 402 and a cutter assembly 403 slidably arranged on the slide rail 401. The slide rail 401 is connected to the bracket 1, and the shaping assembly 402 and the cutter assembly 403 are spaced apart in the length direction of the slide rail 401.

[0048] It can be understood that the cutter assembly 403 of the shaping assembly 402 is arranged on the same slide rail 401, thereby avoiding the need to set up too many slide rails 401, thereby reducing the complexity and manufacturing cost of the coal sampling and cutting equipment of the embodiment of the utility model.

[0049] like Figure 2 As shown, the shaping component 402 includes a shaping sliding member 4021 slidably set on the slide rail 401 and a mixing component 4022 arranged below the shaping sliding member 4021 and connected to the shaping sliding member 4021 through a second telescopic member 4023, the mixing component 4022 includes a mixing support plate 40221, the mixing support plate 40221 is connected to the lower end of the second telescopic member 4023, a mixing motor 40222 is arranged on the mixing support plate 40221, the output shaft of the mixing motor 40222 passes through the mixing support plate 40221 and extends downward, and the lower end of the output shaft of the mixing motor 40222 is provided with a mixing plate 40223.

[0050] When the coal in the feed barrel enters the distribution barrel 201 through the feed port, the shaping slide 4021 is used to move the mixing component 4022 from the initial position of the mixing component 4022 along the length direction of the slide rail 401 to above the distribution barrel 201, and then the mixing component 4022 is gradually lowered into the distribution barrel 201 by the second telescopic component 4023. At the same time, the mixing plate 40223 of the mixing component 4022 is driven by the mixing motor 4022 to rotate to flatten the coal in the distribution barrel 201. After the coal in the distribution barrel 201 is flattened, the second telescopic component 4023 drives the mixing component 4022 to rise, and the shaping slide 4021 drives the mixing component 4022 to move along the length direction of the slide rail 401 to the initial position of the mixing component 4022.

[0051] It can be understood that the initial position of the mixing component 4022 can be a position that does not interfere with the operation of other components. For example, the mixing component 4022 is located at one end of the slide rail 401.

[0052] like Figure 2 As shown, the cutter assembly 403 includes a cutter slide 4031 and a cross cutter 4032. The cross cutter 4032 is arranged below the cutter slide 4031, and the cross cutter 4032 is connected to the cutter slide 4031 through a first telescopic member 4033 to drive the cross cutter 4032 to move in the up and down directions. The cutter slide 4031 is slidably set on the slide rail 401 to drive the cross cutter 4032 to move in the horizontal direction.

[0053] It can be understood that the cross cutter 4032 is moved from the initial position of the cross cutter 4032 to above the dividing barrel 201 along the length direction of the slide rail 401 by the cutter slide 4031, and then the cross cutter 4032 is driven by the first telescopic member 4033 to move downward into the dividing barrel 201 to cut the coal. After the cutting is completed, the cross cutter 4032 is driven by the first telescopic member 4033 to move upward to the outside of the dividing barrel 201, and then the cross cutter 4032 is moved along the length direction of the slide rail 401 to the initial position of the cross cutter 4032 by the cutter slide 4031, thereby completing the cutting of the coal.

[0054] It can be understood that the initial position of the slitting assembly can be a position that does not interfere with the operation of other components, for example, the slitting assembly is located at the other end of the slide rail 401.

[0055] The bottom plate 202 is divided into four right-angled sector-shaped material dividing plates 2021 which are sequentially arranged along the circumference of the material dividing barrel 201, and the right-angled sides of adjacent right-angled sector-shaped material dividing plates 2021 define a cross material dividing line 2022;

[0056] The blade of the cross cutter 4032 is arranged corresponding to the cross dividing line 2022, so that the cross cutter 4032 can cooperate with the cross dividing line 2022 when moving into the dividing barrel 201 to divide the dividing barrel 201 into a first chamber 203, a second chamber 204, a third chamber 205 and a fourth chamber 206 spaced along the circumference of the dividing barrel 201, the first chamber 203 and the third chamber 205 are diagonally arranged, and the second chamber 204 and the fourth chamber 206 are diagonally arranged.

[0057] The four right-angled sector-shaped material dividing plates 2021 are respectively arranged corresponding to the first chamber 203 , the second chamber 204 , the third chamber 205 and the fourth chamber 206 , and the right-angled sector-shaped material dividing plates 2021 are movable in the radial direction of the material dividing barrel 201 .

[0058] It can be understood that the cross cutter 4032 is moved from the initial position of the cross cutter 4032 to the top of the dividing barrel 201 along the length direction of the slide rail 401 by the cutter slide 4031, and then the cross cutter 4032 is driven by the first telescopic member 4033 to move downward into the dividing barrel 201 to cut the coal, and then the right-angle fan-shaped dividing plate 2021 is moved to allow the coal in the first chamber 203, the second chamber 204, the third chamber 205 and the fourth chamber 206 to flow out, and then the coal flowing out of the first chamber 203, the second chamber 204, the third chamber 205 and the fourth chamber 206 is collected, and the next step is carried out.

[0059] The coal sampling and cutting equipment of the embodiment of the utility model can accurately cut the coal and collect the cut coal separately by setting the feeding component 3, the dividing component 2, the shaping and cutting component 4 and the collecting component 8, thereby avoiding the error generated in the cutting process affecting the accuracy of the subsequent data.

[0060] In some embodiments, the feeding assembly 3 includes a feeding barrel and a fixed plate 302. The bottom of the feeding barrel is an inverted cone, and the lower end of the feeding barrel has a feeding port. The feeding barrel is arranged on the fixed plate 302 through an elastic assembly 303. A vibration motor is arranged on the feeding barrel. The fixed plate 302 is connected to the bracket 1, and a feeding opening is arranged on the fixed plate 302 corresponding to the feeding port.

[0061] Preferably, the elastic component 303 includes elastic members 3031 arranged at intervals along the circumference of the feeding cylinder, the upper end of the elastic member 3031 is connected to the feeding cylinder, and the lower end of the elastic member 3031 is connected to the fixing plate 302 .

[0062] It can be understood that by arranging the elastic member 3031 between the feeding barrel and the fixed plate 302, the feeding barrel 301 can vibrate under the drive of the vibration motor, so that the coal in the feeding barrel 301 can quickly fall into the distribution barrel 201 through the feeding port, thereby avoiding the problem of coal in the feeding barrel 301 being blocked. At the same time, the elastic member 3031 can also avoid the vibration of the feeding barrel 301 from being transmitted to the fixed plate 302 as much as possible.

[0063] In some embodiments, the shaping component 402 includes a shaping sliding member 4021 slidably set on the slide rail 401 and a mixing component 4022 arranged below the shaping sliding member 4021 and connected to the shaping sliding member 4021 through a second telescopic member 4023, the mixing component 4022 includes a mixing support plate 40221, the mixing support plate 40221 is connected to the lower end of the second telescopic member 4023, a mixing motor 40222 is arranged on the mixing support plate 40221, the output shaft of the mixing motor 40222 passes through the mixing support plate 40221 and extends downward, and a mixing plate 40223 is arranged at the lower end of the output shaft of the mixing motor 40222.

[0064] When the coal in the feed barrel enters the distribution barrel 201 through the feed port, the shaping slide 4021 is used to move the mixing component 4022 from the initial position of the mixing component 4022 along the length direction of the slide rail 401 to above the distribution barrel 201, and then the mixing component 4022 is gradually lowered into the distribution barrel 201 by the second telescopic component 4023. At the same time, the mixing plate 40223 of the mixing component 4022 is driven by the mixing motor 4022 to rotate to flatten the coal in the distribution barrel 201. After the coal in the distribution barrel 201 is flattened, the second telescopic component 4023 drives the mixing component 4022 to rise, and the shaping slide 4021 drives the mixing component 4022 to move along the length direction of the slide rail 401 to the initial position of the mixing component 4022.

[0065] It can be understood that the initial position of the mixing component 4022 can be a position that does not interfere with the operation of other components. For example, the mixing component 4022 is located at the other end of the slide rail 401.

[0066] In some embodiments, the material dividing assembly 2 further includes four third telescopic members 5 , and the telescopic ends of the four third telescopic members 5 are respectively connected to four right-angled sector-shaped material dividing plates 2021 to drive the right-angled sector-shaped material dividing plates 2021 to move radially in the material dividing barrel 201 .

[0067] Preferably, the third telescopic member 5 is an electric push rod.

[0068] In some embodiments, the shaping and slitting assembly 4 also includes a fourth telescopic member 6 and a fifth telescopic member 7, which are arranged on the bracket 1, and the telescopic end of the fourth telescopic member 6 is connected to the cutter slide 4031 to drive the cutter slide 4031 to slide along the length direction of the slide rail 401, and the telescopic end of the fifth telescopic member 7 is connected to the shaping slide 4021 to drive the shaping slide 4021 to slide along the length direction of the slide rail 401.

[0069] Preferably, the fourth telescopic member 6 and the fifth telescopic member 7 are electric push rods.

[0070] In some embodiments, the coal sampling and cutting equipment of the utility model embodiment also includes an aggregate assembly 8, the aggregate assembly 8 includes an aggregate barrel 801, and a cross partition 802 is arranged inside the aggregate barrel 801 to divide the interior of the aggregate barrel 801 into a fifth chamber 803, a sixth chamber 804, a seventh chamber 805 and an eighth chamber 806 corresponding to the four right-angle fan-shaped dividing plates 2021; the areas at the bottom of the aggregate barrel 801 corresponding to the fifth chamber 803, the sixth chamber 804, the seventh chamber 805 and the eighth chamber 806 are respectively provided with a first discharge port 8031, a second discharge port 8041, a third discharge port 8051 and a fourth discharge port 8061.

[0071] It can be understood that the fifth chamber 803, the sixth chamber 804, the seventh chamber 805 and the eighth chamber 806 of the collecting barrel 801 correspond to the four right-angle fan-shaped dividing plates 2021 respectively. In other words, the fifth chamber 803, the sixth chamber 804, the seventh chamber 805 and the eighth chamber 806 of the collecting barrel 801 correspond to the first chamber 203, the second chamber 204, the third chamber 205 and the fourth chamber 206 of the dividing barrel 201 respectively.

[0072] Therefore, when the four right-angle fan-shaped dividing plates 2021 are moved, the coal in the first chamber 203, the second chamber 204, the third chamber 205 and the fourth chamber 206 can fall into the fifth chamber 803, the sixth chamber 804, the seventh chamber 805 and the eighth chamber 806 respectively, so that the coal after cutting can be collected separately, and then the staff can select the collected coal for re-cutting or the next experimental process as needed.

[0073] Furthermore, the areas at the bottom of the collecting barrel 801 corresponding to the fifth chamber 803 , the sixth chamber 804 , the seventh chamber 805 and the eighth chamber 806 are all inverted cones to facilitate the coal to flow out of the fifth chamber 803 , the sixth chamber 804 , the seventh chamber 805 and the eighth chamber 806 .

[0074] In order to collect the coal flowing out of the fifth chamber 803 , the sixth chamber 804 , the seventh chamber 805 and the eighth chamber 806 , a collecting cylinder 9 is provided below the first discharge port 8031 ​​, the second discharge port 8041 , the third discharge port 8051 and the fourth discharge port 8061 .

[0075] The working principle of the coal sample preparation and cutting device in the embodiment of the utility model is described below.

[0076] The staff first adds the coal to be cut into the feeding barrel, and the coal enters the dividing barrel 201 through the feeding port to form a conical coal pile. Then, the shaping sliding member 4021 is used to move the mixing component 4022 from the initial position of the mixing component 4022 along the length direction of the slide rail 401 to above the dividing barrel 201. Then, the mixing component 4022 is gradually lowered into the dividing barrel 201 by the second telescopic member 4023. At the same time, the mixing plate 40223 of the mixing component 4022 is driven by the mixing motor 4022 to rotate to flatten the coal pile in the dividing barrel 201. After the coal pile in the dividing barrel 201 is flattened, the second telescopic member 4023 drives the mixing component 4022 to rise, and the shaping sliding member 4021 drives the mixing component 4022 to move along the length direction of the slide rail 401 to the initial position of the mixing component 4022.

[0077] The cross cutter 4032 is moved from the initial position of the cross cutter 4032 to the top of the material distribution barrel 201 along the length direction of the slide rail 401 by the cutter sliding member 4031, and then the cross cutter 4032 is driven by the first telescopic member 4033 to move downward into the material distribution barrel 201 to cut the coal material. At this time, the cross cutter 4032 cuts the coal material in the material distribution barrel 201 into four parts, which are respectively accommodated in the first to fourth chambers 206, and then the third telescopic member 5 is used to drive the right-angle fan-shaped material distribution plate 2021 to move outward in the radial direction of the material distribution barrel 201 to open the first to fourth chambers 206. The bottom of the first to fourth chambers 206 is made so that the coal in the first to fourth chambers 206 falls into the fifth to eighth chambers 806 in the collecting barrel 801. After the coal has completely fallen into the fifth to eighth chambers 806, the third telescopic member 5 drives the right-angle fan-shaped dividing plate 2021 to move inwardly in the radial direction of the dividing barrel 201 to close the bottom of the first to fourth chambers 206. At the same time, the first telescopic member 4033 drives the cross cutter 4032 to move upward to the outside of the dividing barrel 201, and then the cross cutter 4032 is moved along the length direction of the slide rail 401 to the initial position of the cross cutter 4032 through the cutter sliding member 4031.

[0078] Then, the coal materials in the fifth to eighth chambers 806 enter the corresponding receiving barrels 9 through the first to fourth discharge ports 8061 respectively, thereby completing the cutting of the coal samples.

[0079] The coal sampling and cutting equipment of the embodiment of the utility model can accurately cut the coal by setting the feeding component 3, the dividing component 2, the shaping and cutting component 4 and the gathering component 8, thereby avoiding the error generated during the cutting process that affects the accuracy of the subsequent data.
