The materials are put into the feeding hopper 2, the materials fall through the feeding hopper 2 to the cutting assembly 4 below, the cutting assembly 4 comprises the first groove group 41 and the second groove group 42 arranged alternately in sequence, and the number of the first groove group 41 and the second groove group 42 is the same, so that in the process of uniform reciprocating movement of the cutting assembly 4, the materials fall into different first groove groups 41 and second groove groups 42 uniformly, and fall into different collecting tanks below along the first groove group 41 and the second groove group 42, that is, the materials are cut into two parts, and the materials in each part are equally divided, and the mass and composition of each part can accurately represent the original sample.

[0054] As Figures 1-7As shown, in this embodiment, the feed hopper 2 is an inverted conical structure with a rectangular cross-section, made of 2mm carbon steel plate. It has an upper opening of 300*260mm, a lower opening of 150*100mm, and a height of 110mm. It can collect materials from different conveying devices or added manually, allowing the materials to converge at a single inlet, facilitating subsequent reduction operations and preventing material dispersion that could affect the accuracy and efficiency of reduction. Simultaneously, the inclined sidewalls of the feed hopper 2 can buffer the materials, partially regulating their flow direction and speed, allowing them to enter the cutting assembly 4 below in a more suitable state for reduction. This ensures a more uniform and orderly distribution of materials during the reduction process, improving reduction accuracy. The feed hopper 2 is mounted above the support frame 1, the moving frame 3 is arranged below the feed hopper 2, and the cutting assembly 4 is mounted on the moving frame 3. Driven by the drive component 5 and the transmission component 6, the moving frame 3 drives the cutting assembly 4 along... Figure 1 The feed hopper moves in a straight line from left to right. When it reaches the left limit position, the lower opening of the feed hopper 2 is aligned with the rightmost end of the cutting component 4. When it reaches the right limit position, the lower opening of the feed hopper 2 is aligned with the leftmost end of the cutting component 4. Figure 2 and Figure 5 As shown, the first grid group 41 and the second grid group 42 are arranged closely together to ensure that the falling material enters each grid group evenly and does not spill out. Figure 1 , Figure 3 and Figure 4 As shown, the upper ends of the first grid group 41 and the second grid group 42 are both connected to the moving frame 3, and the lower ends extend to the left and right sides respectively, and their projections on the vertical plane do not overlap. Therefore, the materials falling through the first grid group 41 and the second grid group 42 can be completely separated and fall into different collection tanks. Depending on the actual application, the driving component 5 can be any driving structure, such as a motor, and the transmission component 6 can also be set to any structural combination, as long as it can drive the moving frame 3 to move back and forth linearly under the drive of the driving component 5.

[0055] Optionally, the transmission assembly 6 includes a crank 61, a first transmission rod 62, and a second transmission rod 63. The first end of the crank 61 is driven to rotate by the driving member 5; the first end of the first transmission rod 62 is rotatably connected to the second end of the crank 61; the first end of the second transmission rod 63 is rotatably connected to the second end of the first transmission rod 62, and the second end of the second transmission rod 63 is fixedly connected to the movable frame 3. This arrangement simplifies the structure of the transmission assembly 6 and facilitates assembly and operation.

[0056] like Figure 1 and Figure 2As shown in the figure, in this embodiment, the driving member 5 is selected as a motor, the left end of the crank rod 61 is fixedly connected with the output shaft of the motor, the right end is rotatably connected with the left end of the first transmission rod 62, the right end of the first transmission rod 62 is rotatably connected with the left end of the second transmission rod 63, and the right end of the second transmission rod 63 is fixedly connected with the moving frame 3. When the material needs to be divided, the motor is started, the output shaft of the motor rotates, drives the crank rod 61 to rotate around the output shaft with the length of the crank rod 61 as the radius, and drives the first transmission rod 62 to move left and right while moving up and down to a certain extent in the process of rotating the crank rod 61. The movement of the first transmission rod 62 further drives the second transmission rod 63 to move left and right, and the movement of the second transmission rod 63 finally drives the moving frame 3 and the cutting assembly 4 to move left and right. In this embodiment, the length of the crank rod 61 is 285 mm, and the length of the second transmission rod 63 is 175 mm. According to the actual application, the specific lengths of the crank rod 61, the first transmission rod 62 and the second transmission rod 63 can be matched and adjusted.

[0057] Optionally, the transmission assembly 6 further comprises a guide member 64 fixed to the support frame 1, the guide member 64 penetrates to form a guide hole, and the second transmission rod 63 penetrates the guide hole. The guide member 64 is arranged to constrain and limit the second transmission rod 63, so as to ensure that the second transmission rod 63 moves linearly and reciprocatingly in the same horizontal plane.

After the second transmission rod 63 penetrates the guide hole, the left end is rotatably connected with the first transmission rod 62, and the right end is fixedly connected with the moving frame 3. After the driving member 5 is started, under the transmission of the crank rod 61 and the first transmission rod 62 and under the limiting action of the guide member 64, the second transmission rod 63 can only move linearly and reciprocatingly along the extension direction of the guide member 64. According to the actual application, the specific shape and size of the guide member 64 can be adjusted, as long as it can constrain the second transmission rod 63 to move linearly and reciprocatingly along the set movement path of the moving frame 3.

[0059] Optionally, the automatic dividing device further comprises a guide rail 7 and a roller 8. The guide rail 7 is fixed to the support frame 1 and parallel to the movement direction of the moving frame 3; and the roller 8 is fixed to the moving frame 3 and rolls along the guide rail 7. This arrangement simplifies the structure of the movable connection between the moving frame 3 and the support frame 1, and facilitates assembly and operation.

[0060] As shown in the figure, Figure 1 and Figure 5As shown, in the present embodiment, parallel to the moving direction of the moving frame 3, guide rails 7 are arranged on the opposite sides of the moving frame 3, and the opposite sides of the moving frame 3 are respectively fixed with rollers 8 which are overlapped on the guide rails 7 on the same side and can roll along the guide rails 7. When the moving frame 3 and the cutting assembly 4 are driven by the driving member 5 and the transmission assembly 6 to move linearly back and forth, the rollers 8 move linearly back and forth along the guide rails 7 synchronously, which ensures the stability of the moving frame 3 and the cutting assembly 4.

As Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the first groove group 41 includes a first vertical unloading groove 411 and a first inclined unloading groove 412; the first vertical unloading groove 411 includes a first inclined section 4111 and a first vertical section 4112, the first end of the first inclined section 4111 is connected to the moving frame 3, and the second end of the first inclined section 4111 is connected to the first vertical section 4112; the inclined surface of the first inclined unloading groove 412 is arranged at an angle with the horizontal plane, and the projections of the first vertical unloading groove 411 and the first inclined unloading groove 412 on the vertical plane away from the one end of the inlet hopper 2 do not have overlapping areas; the second groove group 42 includes a second vertical unloading groove and a second inclined unloading groove; the second vertical unloading groove includes a second inclined section and a second vertical section, the first end of the second inclined section is connected to the moving frame 3, and the second end of the second inclined section is connected to the second vertical section; the inclined surface of the second inclined unloading groove is arranged at an angle with the horizontal plane, and the projections of the second vertical unloading groove and the second inclined unloading groove on the vertical plane away from the one end of the inlet hopper 2 do not have overlapping areas; the four collecting grooves are respectively located below the first vertical unloading groove 411, the first inclined unloading groove 412, the second vertical unloading groove and the second inclined unloading groove.

[0062] The above arrangement divides the first groove group 41 into the first vertical unloading groove 411 and the first inclined unloading groove 412, divides the second groove group 42 into the second vertical unloading groove and the second inclined unloading groove, and the projections of the four lower end outlets on the vertical plane do not have overlapping areas, that is, in the process of uniform movement of the moving frame 3, the materials in the inlet hopper 2 are evenly dropped into the first vertical unloading groove 411, the first inclined unloading groove 412, the second vertical unloading groove and the second inclined unloading groove, and are dropped into the independent four collecting grooves without affecting each other, realizing equal four-division of the materials.

The first inclined section 4111 is arranged at an angle with the horizontal plane, guiding the falling material to smoothly enter the first vertical section 4112 along the inclined inner wall. The cooperation of the first inclined section 4111 and the first vertical section 4112 changes the migration trajectory of the material, so that the migration trajectory of the material in the first inclined chute 412 is different from that in the second inclined chute, so that the materials in the two chutes can fall into different collection tanks below. The second vertical chute has the same structure as the first vertical chute 411, and the inclined direction is opposite. The second inclined chute has the same structure as the first inclined chute 412, and the inclined direction is opposite. Details are not repeated here. According to actual application conditions, the specific shape and size of the first vertical chute 411, the first inclined chute 412, the second vertical chute and the second inclined chute can be matched and adjusted, as long as they can equally receive the material falling from the hopper 2 and guide the material to fall into the corresponding collection tank below.

[0064] Optionally, the angle between the inclined surface of the first inclined chute 412 and the horizontal plane is greater than or equal to 60°; the angle between the inclined surface of the second inclined chute and the horizontal plane is greater than or equal to 60°. By setting the angle between the first inclined chute 412, the second inclined chute and the horizontal plane within the above range, it is helpful for the material to smoothly slide along the inner wall of the inclined chute and be guided into the corresponding collection tank below.

[0066] As Figure 1 shown in the embodiment, the left and right sides of the mobile frame 3 are respectively fixed with the protective plates 9, the left end of the cutting assembly 4 abuts against the left protective plate 9, and a certain spacing exists between the right end and the right protective plate 9, the clamping rod 10 penetrates through the right protective plate 9 and is threadedly connected with the right protective plate 9, and the clamping rod 10 is screwed in until the left end of the clamping rod 10 abuts against the right end of the cutting assembly 4, so that the cutting assembly 4 is limited.

[0067] Optionally, the end of the clamping rod 10 away from the cutting assembly 4 is connected with the handle 11. The handle 11 is arranged, and in the process of screwing in the clamping rod 10, the handle 11 can be held to screw in, so that the rotating operation is facilitated. Figure 1 As
