[0059] In order to make the technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0060] Figures 1-7 Structure diagram of the roller compactor in another specific embodiment of the present application. As shown in the figure, the roller compactor in one specific embodiment of the present application comprises a base 11, a flat plate 12, a barrel 13, a roller 14, a first connecting rod 15, a second connecting rod 16, a supporting device 17 and a driving device (not shown in the figure); Figure 1

[0061] One end of the base 11 is provided with a support 111; a limiting hole 112 is arranged on the support 111;

[0062] The flat plate 12 is arranged above the base 11, and one side edge of the flat plate 12 is rotationally connected with the base 11;

[0063] The barrel 13 is arranged on the upper surface of the flat plate 12; the barrel 13 is a cylindrical container with an opening at the top; the bottom of the barrel 13 is rotationally connected with the flat plate 12 through a transmission shaft 32; a containing groove 31 is arranged at the center of the inner side of the bottom of the barrel 13; the included angle formed by the side wall and the bottom surface of the barrel 13 is a first included angle;

[0064] The roller 14 comprises a first cone 41 and a second cone 42 with the same bottom surface diameter; the bottom of the first cone 41 and the second cone 42 are fixedly connected, and the second included angle formed by the generatrix of the first cone 41 and the second cone 42 is equal to the first included angle;

[0065] The first end of the first connecting rod 15 is fixedly connected with the top of the first cone 41, and the second end of the first connecting rod 15 is rotationally connected with the containing groove 31 at the bottom of the barrel 13;

[0066] The first end of the second connecting rod 16 is fixedly connected with the top of the second cone 42, and the second end of the second connecting rod 16 passes through the limiting hole 112 on the support of the base 11;

[0067] The first connecting rod 15, the second connecting rod 16, the first cone 41 and the second cone 42 are coaxial;​

[0068] One end of the support device 17 is fixedly connected with the bottom of the flat plate 12, and the other end is fixedly connected with the base 11; the support device 17 has a telescopic structure;

[0069] The driving device is connected with the transmission shaft of the support device 17 and the barrel 13, and is used to drive the support device 17 to extend or shorten, and is used to drive the barrel 13 to rotate around the central axis.

[0070] When the roller is needed to be used, the support device can be driven by the driving device to extend or shorten by a corresponding length, so that the flat plate and the base form a preset first angle (for example, the first angle can be equal to the half angle of the first cone, that is, the included angle between the generatrix and the axis), so that the first connecting rod and the second connecting rod are in a horizontal state. Then, the transmission shaft of the barrel can be driven by the driving device, so that the barrel starts to rotate in a preset direction (for example, clockwise or counterclockwise). Before or after the barrel starts to rotate, the material to be crushed can be put into the barrel. After the barrel starts to rotate, the roller will also start to rotate, so that the roller can crush the material in the barrel. At this time, the first connecting rod and the second connecting rod are in a horizontal state. Since the first connecting rod, the second connecting rod, the first cone and the second cone are coaxial, that is, have the same rotation axis, the rotation axis of the roller (that is, the line connecting the apexes of the first cone and the second cone) will also be in a horizontal direction; and since the second included angle formed by the generatrices of the first cone and the second cone is equal to the first included angle formed by the side wall and the bottom surface of the barrel, the generatrix of the first cone will closely fit the bottom surface of the barrel, and the generatrix of the second cone will closely fit the side wall of the barrel. Therefore, the roller will not leave dead angles when crushing the material in the barrel, so that the material can be more fully crushed, improving the crushing efficiency.

[0071] In addition, when the crushing of the material is completed, the support device can also be driven by the driving device to extend by a corresponding length, so that the flat plate and the base form a preset second angle (for example, 90°, or the side wall of the barrel is parallel to the surface of the base, or other suitable angles), so as to facilitate the removal of the material from the barrel, and further facilitate the cleaning or washing of the barrel.

[0072] In addition, as an example, in a preferred embodiment of the present application, the width of the limiting hole on the bracket is equal to or slightly greater than the diameter of the second end of the second connecting rod, and the length of the limiting hole (i.e. the length in the vertical direction) is greater than the diameter of the second end of the second connecting rod, so that the second end of the second connecting rod can pass through the limiting hole and be limited in the horizontal direction, but can be displaced in the vertical direction (i.e. the length direction of the limiting hole). Therefore, when there are small or hard blocks in the material in the hopper, the second end of the second connecting rod can move up and down in the limiting hole, so that the roller can be slightly up and down to temporarily cross the small or hard blocks, so as not to be stuck by the small or hard blocks, causing the roller to continue to roll the other materials.

[0073] In addition, as an example, in another preferred embodiment of the present application, the bottom of the limiting hole on the bracket can be further provided with a shock absorber (not shown in the figure) below the second end of the second connecting rod.

[0074] By providing the above-mentioned shock absorber, the shock absorber can play a role in shock absorption when the second end of the second connecting rod falls, thereby effectively reducing the vibration of the roller.

[0075] In addition, as an example, in another preferred embodiment of the present application, the shock absorber can be a spring or other suitable elastic body.

[0076] In addition, as an example, in another preferred embodiment of the present application, the end of the second end of the first connecting rod is in the shape of a spherical segment (for example, the spherical segment can be a spherical segment larger than a hemisphere), and the shape of the spherical segment matches the shape of the accommodating groove at the bottom of the hopper (or the spherical segment is slightly smaller than the accommodating groove at the bottom of the hopper), so that the spherical segment can be clamped in the accommodating groove without falling off, and can also rotate freely in the accommodating groove.

[0077] In addition, as an example, in another preferred embodiment of the present application, the roller press can further comprise a knife holder 18.

[0078] The knife holder 18 comprises a stand 81, a crossbar 82 and at least one scraper assembly 83.

[0079] The stand 81 is arranged outside the hopper 13, and the bottom of the stand 81 is fixedly connected to the upper surface of the flat plate 12.

[0080] One end of the crossbar 82 is fixedly connected to the top of the stand 81, and the other end is located above the opening of the hopper 13.

[0081] The top of the scraper assembly 83 is fixedly connected with the cross bar 82; the bottom of the scraper assembly 83 is provided with a bottom blade, and the bottom of the bottom blade is tightly fitted with the bottom of the barrel 13.

[0082] By setting the above-described knife rest on the roller, the corresponding scraper assembly can be set in the above-described barrel, so that the material possibly adhered to the bottom of the barrel can be scraped off by the bottom blade at the bottom of the scraper assembly, so as to avoid that the material adhered to the bottom of the barrel cannot be fully rolled by the roller, thereby enabling the material to be more fully rolled and ground.

[0083] In addition, in the technical solution of the present application, one or more scraper assemblies can be set in the above-described knife rest according to the actual needs.

[0084] For example, as an example, as shown in Figure 2 and Figure 3 In a preferred embodiment of the present application, the scraper assembly 83 can include a first scraper assembly 84.

[0085] The first scraper assembly 84 includes a first connecting rod 841 and a first bottom blade 842.

[0086] The top of the first connecting rod 841 is fixedly connected with the cross bar 82; the bottom of the first connecting rod 841 is fixedly connected with one end of the first bottom blade 842.

[0087] The bottom of the first bottom blade 842 is tightly fitted with the bottom of the barrel 13.

[0088] Therefore, by the first bottom blade in the above-described first scraper assembly, the material possibly adhered to the bottom of the barrel can be scraped off, so as to avoid that the material adhered to the bottom of the barrel cannot be fully rolled by the roller.

[0089] In addition, in the technical solution of the present application, the length of the above-described first bottom blade can be set in advance according to the actual needs.

[0090] For example, as an example, in a preferred embodiment of the present application, the length of the first bottom blade 842 is less than the radius of the barrel.

[0091] In addition, in the technical solution of the present application, the specific position of the above-described first scraper assembly can also be set in advance according to the actual needs.

[0092] For example, as an example, in a preferred embodiment of the present application, when the barrel rotates in the counterclockwise direction, the first scraper assembly is arranged at the left upper side of the roller, and the extension direction of the first bottom blade 842 points to the left lower side of the roller (as shown inFigure 3 When the barrel rotates in the clockwise direction, the first scraper assembly is arranged at the upper right side of the mill, and the extending direction of the first bottom blade points to the lower right of the mill.

[0093] By the above arrangement, the scraped material can fall into the lower side of the "forward direction" of the mill (i.e. the direction of movement of the mill relative to the side wall of the barrel), so as to be continuously rolled by the mill.

[0094] For example, as shown in FIG. 1, the scraper assembly 83 can include a first scraper assembly 81. Figure 4 and Figure 5 In another preferred embodiment of the present application, the scraper assembly 83 can include a second scraper assembly 85, as shown in FIG. 2.

[0095] The second scraper assembly 85 includes a second connecting rod 851, a second bottom blade 852, and a side blade 853.

[0096] The top of the second connecting rod 851 is fixedly connected with the horizontal rod 82; the side of the second connecting rod 851 is fixedly connected with one side of the side blade 853; and the bottom of the second connecting rod 851 is fixedly connected with one end of the second bottom blade 852.

[0097] One side of the side blade 853 is closely fitted with the side wall of the barrel 13.

[0098] The bottom of the second bottom blade 852 is closely fitted with the bottom of the barrel 13.

[0099] Therefore, the second side blade in the second scraper assembly can scrape the material that may be adhered to the side wall of the barrel, so as to avoid that the material adhered to the side wall cannot be fully rolled by the mill; and the second bottom blade in the second scraper assembly can scrape the material that may be adhered to the bottom of the barrel, so as to avoid that the material adhered to the bottom cannot be fully rolled by the mill.

[0100] In addition, in the technical solution of the present application, the length of the second bottom blade can be set in advance according to the actual needs.

[0101] For example, as shown in FIG. 1, in a preferred embodiment of the present application, the length of the second bottom blade is less than the radius of the barrel.

[0102] In addition, in the technical solution of the present application, the specific position of the second scraper assembly can also be set in advance according to the actual needs.

[0103] For example, as an example, in a preferred embodiment of the invention, when the hopper rotates counterclockwise, the second scraper assembly is disposed on the upper left side of the millstone, and the extension direction of the second bottom blade points to the lower right side of the millstone (e.g., Figure 5 (as shown); when the hopper rotates clockwise, the second scraper assembly is located on the upper right side of the millstone, and the extension direction of the second bottom blade points to the lower left side of the millstone.

[0104] With the above settings, the scraped material can pass over the other end of the second bottom blade and fall below the "forward direction" of the mill (i.e., the direction of movement of the mill relative to the side wall of the hopper), so that it can be further crushed by the mill.

[0105] For example, as an example, such as Figure 1 and Figure 6 As shown, in another preferred embodiment of the present invention, the scraper assembly 83 may include: a first scraper assembly 84 and a second scraper assembly 85;

[0106] The first scraper assembly 84 includes: a first connecting rod 841 and a first bottom blade 842;

[0107] The top of the first connecting rod 841 is fixedly connected to the crossbar 82; the bottom of the first connecting rod 841 is fixedly connected to one end of the first bottom blade 842.

[0108] The bottom of the first bottom blade 842 is in close contact with the bottom of the material barrel 13;

[0109] The second scraper assembly 85 includes: a second connecting rod 851, a second bottom blade 852, and a side blade 853;

[0110] The top of the second connecting rod 851 is fixedly connected to the crossbar 82; the side of the second connecting rod 851 is fixedly connected to one side of the side blade 853; the bottom of the second connecting rod 851 is fixedly connected to one end of the second bottom blade 852.

[0111] One side of the side blade 853 is in close contact with the side wall of the material barrel 13;

[0112] The bottom of the second bottom blade 852 is in close contact with the bottom of the material bucket 13.

[0113] Therefore, by the first bottom blade in the first scraper assembly and the second bottom blade in the second scraper assembly, the material possibly adhered to the bottom of the barrel can be scraped off, so as to avoid that the material adhered to the bottom of the barrel cannot be fully rolled by the roller; and by the second side blade in the second scraper assembly, the material possibly adhered to the side wall of the barrel can be scraped off, so as to avoid that the material adhered to the side wall cannot be fully rolled by the roller.

[0114] In addition, in the technical solution of the present application, the lengths of the first bottom blade and the second bottom blade can be set in advance according to actual needs.

[0115] For example, as an example, in a preferred embodiment of the present application, the lengths of the first bottom blade and the second bottom blade are both less than the radius of the barrel.

[0116] In addition, in the technical solution of the present application, the specific positions of the first scraper assembly and the second scraper assembly can also be set in advance according to actual needs.

[0117] For example, as an example, in a preferred embodiment of the present application, when the barrel rotates in the counterclockwise direction, the first scraper assembly and the second scraper assembly are both arranged on the upper left side of the roller, the first bottom blade is located below the side of the second bottom blade; the extension direction of the first bottom blade points to the lower left of the roller, and the extension direction of the second bottom blade points to the lower right of the roller (as shown in Figure 6 When the barrel rotates in the clockwise direction, the first scraper assembly and the second scraper assembly are both arranged on the upper right side of the roller, the first bottom blade is located below the side of the second bottom blade; the extension direction of the first bottom blade points to the lower right of the roller, and the extension direction of the second bottom blade points to the lower left of the roller.

[0118] Through the above arrangement, the scraped material can pass the other end of the second bottom blade and the other end of the first bottom blade to fall below the "forward direction" of the roller (i.e. the movement direction of the roller relative to the side wall of the barrel), so as to be continuously rolled by the roller.

[0119] In addition, in the technical solution of the present application, the size of the first included angle (i.e. the included angle between the side wall and the bottom of the barrel) can also be set in advance according to actual needs.

[0120] For example, as an example, in a preferred embodiment of the present application, the first included angle is not less than 40 degrees.

[0121] For example, in a preferred embodiment of the present application, the first angle is greater than or equal to 40 degrees and less than or equal to 75 degrees.

[0122] In addition, in the technical solution of the present application, the size of the top angle of the first and second cones can be set in advance according to the actual situation.

[0123] For example, in a preferred embodiment of the present application, the top angle of the first and second cones is greater than or equal to 20 degrees and less than or equal to 100 degrees.

[0124] In addition, as shown in Figure 7 In a preferred embodiment of the present application, the support device 17 can include two support rods 71.

[0125] The two support rods 71 are respectively arranged on the two sides of the base 11 and are connected with the driving device. One end of each of the two support rods 71 is fixedly connected with the bottom of the flat plate 12, and the other end is fixedly connected with the base 11. Each of the support rods 71 has an extendable structure.

[0126] Through the extendable structure of the two support rods, the flat plate can be pushed to form a required angle (for example, the first angle or the second angle) with the base under the driving of the driving device, and the flat plate is supported accordingly.

[0127] In addition, in a preferred embodiment of the present application, the driving device can be a motor or other suitable driving device.

[0128] In summary, in the technical solution of the present application, the flat plate is arranged on the base, the barrel is arranged on the flat plate, the roller including the first and second cones is arranged in the barrel, and the second angle formed by the generatrix of the first and second cones is equal to the first angle formed by the side wall and the bottom of the barrel. Therefore, the generatrix of the first cone will closely fit the bottom of the barrel, and the generatrix of the second cone will closely fit the side wall of the barrel. Therefore, the roller will not leave dead angles when rolling the material in the barrel, so that the material can be rolled more fully, and the rolling efficiency is improved.

[0129] The above only describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
