Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0028] See also Figure 1 and Figure 2 The embodiment of the present application provides a coal cake tamping machine, which includes a housing 1, a tamping assembly 3, a driving assembly, a counting assembly 4 and a controller. The housing 1 has a containing chamber 11 and an opening connected to the containing chamber 11 along a first direction X, and the containing chamber 11 is configured to contain a coal cake material body 2 to be tamped. The tamping assembly 3 includes a supporting assembly 32 and a tamping hammer 31, and the tamping hammer 31 is arranged on the supporting assembly 32, and the tamping hammer 31 has a degree of freedom of movement relative to the supporting assembly 32 in the first direction X. The driving assembly is connected to the tamping hammer 31 and drives the tamping hammer 31 to reciprocate along the first direction X to tamp the coal cake material body, the counting assembly 4 is arranged on the supporting assembly 32, and the counting assembly 4 is configured to count the number of reciprocating movements of the tamping hammer 31 along the first direction X, and the controller is electrically connected to the driving assembly and the counting assembly 4, and the controller is configured to control the driving assembly according to the number of times.

[0029] The box body 1 can be cylindrical or polygonal, and the specific shape can be determined according to the coal cakes to be formed.

[0030] The first direction X may be the height direction or the axial direction of the box body 1 .

[0031] The freedom of movement between the tamping hammer 31 and the support assembly 32 can be understood as the two can be connected in the form of a guide rail slider. Of course, they can also be connected in the form of one being inserted into the other and having a clearance fit with each other to ensure the support of the support assembly 32 for the tamping hammer 31 and the movement requirements of the tamping hammer 31.

[0032] The drive assembly and the tamping hammer 31 may be connected directly or indirectly, for example, by adding a transmission mechanism between the two. The drive assembly includes but is not limited to a telescopic cylinder, a drive motor, and the like.

[0033] The counting component 4 can count by means of a proximity switch 43 or the like, or by means of voice control or the like, for example, counting by counting the sound produced when the tamping hammer 31 hits the coal cake material body 2 to be tamped.

[0034] The box body 1 has a receiving chamber 11 and an opening connected to the receiving chamber 11 along a first direction X. The briquettes material body 2 to be tamped is placed in the receiving chamber 11. The tamping hammer 31 can partially extend into the receiving chamber 11 and tamp the briquettes material body 2 to be tamped. Optionally, the first direction X is a vertical direction. The support assembly 32 is used to support the tamping hammer 31. The optional controller is a plc, which is a prior art and will not be described in detail here.

[0035] In summary, according to the coal cake tamping machine provided by an embodiment of the present application, when the driving component of the coal cake tamping machine drives the tamping hammer 31 to tamp the coal cake material body 2 to be tamped in the box body 1, the counting component 4 can count the number of reciprocating motions of the tamping hammer 31 along the first direction X. When the preset number is reached, the controller controls the driving component to stop driving the tamping hammer 31 to move. Therefore, the coal cake tamping machine can realize automatic counting and stop movement, which brings convenience to the daily operation of the experimenter and is also conducive to precise control of the experiment.

[0036] In some embodiments, the counting component 4 includes a half gear 41, a metal part 42 and a proximity switch 43. The tamping hammer 31 is provided with a rack 3111 distributed along the first direction X and meshing with the half gear 41. The metal part 42 is arranged on the half gear 41 and rotates with the half gear 41 to trigger the proximity switch 43. The driving component is connected to the tamping hammer 31 and one of the half gears 41.

[0037] The half gear 41 includes a gear body, and gear teeth are arranged on part of the circumference of the gear body, and the other part of the circumference is a smooth surface. Optionally, gear teeth are arranged on half of the circumference of the gear body, and the other half of the circumference is a smooth surface. The metal piece 42 is a strip structure, and the metal piece 42 can be arranged on the half gear 41 by welding or the like. Optionally, the metal piece 42 can be an iron sheet. Optionally, the proximity switch 43 can be a magnetic proximity switch 43.

[0038] In a coal cake tamping machine provided by an embodiment of the present application, a driving assembly drives a half gear 41 to rotate, and the half gear 41 meshes with a rack 3111 arranged on the tamping hammer 31 and distributed along the first direction X, thereby driving the tamping hammer 31 to move along the first direction X on the supporting assembly 32. At the same time, during the rotation of the half gear 41, a metal part 42 arranged on the half gear 41 will rotate together with the half gear 41. The proximity switch 43 is triggered once for each rotation of the half gear 41, so that the counting assembly 4 counts the number of reciprocating movements of the tamping hammer 31 along the first direction X, and the structure is simple. In addition, the rotation of the half gear 41 drives the tamping hammer to move up and down, which can ensure that each stroke is consistent.

[0039] In some embodiments, the driving assembly includes a driving motor, which is connected to the half gear 41 and drives the half gear 41 to rotate, so as to drive the tamping hammer 31 to move along the first direction X. It should be noted that the driving assembly also includes a reducer, and the driving motor drives the half gear 41 to move through the reducer. The motor drive has the advantages of high reliability, high precision, high efficiency and energy saving.

[0040] It is understandable that the drive assembly including the drive motor is only some optional embodiments. In some other embodiments, the drive assembly can also include a telescopic cylinder, which is connected to the tamping hammer 31 and has telescopic freedom in the length direction, so as to drive the tamping hammer 31 to move along the first direction X and drive the half gear 41 to rotate to achieve counting. The telescopic cylinder can be used to directly drive the tamping hammer 31 to move along the first direction X, which can also ensure the driving effect and counting requirements of the tamping hammer and improve the safety performance.

[0041] In some embodiments, the proximity switch 43 is disposed at one end of the half gear 41 in the axial direction and is spaced apart from the half gear 41 , the metal piece is located on one end surface of the half gear 41 in the axial direction facing the proximity switch 43 and is connected to the half gear 41 , and the axial direction intersects with the first direction X. Optionally, the axial direction is perpendicular to the first direction X.

[0042] In a coal cake tamping machine provided by an embodiment of the present application, the setting position of the proximity switch 43 can prevent the proximity switch 43 from erroneously counting due to scanning the half gear 41, thereby improving the precision and accuracy of the counting.

[0043] In some embodiments, the tamping hammer 31 includes a hammer head 311 and a hammer handle 312 . The hammer head 311 matches the shape of the accommodating cavity 11 and has a clearance fit with the box body 1 . The hammer handle 312 is connected to the hammer head 311 and the driving assembly.

[0044] The tamping hammer 31 includes a hammer handle 312 and a hammer head 311. The hammer head 311 is connected to the hammer handle 312. The hammer head 311 extends into the accommodating chamber 11 to tamp the coal cake material body 2 to be tamped. The hammer handle 312 can be selected as a regular quadrangular prism structure, and the hammer head 311 can be selected as a plate structure with a rectangular cross-section. The cross-sectional area of ​​the hammer head 311 is greater than the cross-sectional area of ​​the hammer handle 312, and each side of the rectangle of the hammer head 311 is parallel to the corresponding sides of the square cross-sectional area of ​​the hammer handle 312.

[0045] Optionally, the hammer head 311 and the hammer handle 312 are made of steel. The cross-sectional shape of the accommodating chamber 11 is consistent with the cross-sectional shape of the hammer head 311, and the cross-sectional area of ​​the accommodating chamber 11 is slightly larger than the cross-sectional area of ​​the hammer head 311. It should be noted that the hammer handle 312 and the hammer head 311 can be connected by welding, or can be connected together by fasteners such as bolts and nuts. The hammer handle 312 and the hammer head 311 can also be other structures, as long as they can move along the first direction X relative to the support assembly 32 and tamp the coal cake material body 2 to be tamped in the accommodating chamber 11 of the box body 1.

[0046] In some embodiments, the support assembly 32 includes a guide assembly 321 and a frame 322 . The guide assembly 321 is disposed on the frame 322 and cooperates with the hammer handle 312 to guide the tamping hammer 31 to move along the first direction X.

[0047] The coal cake tamping machine provided in one embodiment of the present application can effectively prevent the tamping hammer 31 from tilting during the up and down movement by setting a guide component 321, so that the tamping hammer 31 can reciprocate along the first direction X, so that the coal cake material body can be tamped and flat.

[0048] In some embodiments, the guide assembly 321 includes more than two guide wheels, which are arranged at intervals on the circumference of the hammer handle 312 and abut against the hammer handle 312 .

[0049] In the coal cake tamping machine provided by one embodiment of the present application, the contact between the guide wheel and the hammer handle 312 is point and line contact, and the friction force is small.

[0050] It is understandable that the guide assembly 321 including more than two guide wheels is only an optional implementation. In some embodiments, the guide assembly 321 may also include more than two guide plates, which extend along the length direction of the hammer handle 312. The guide plates are arranged at intervals on the circumference of the hammer handle 312 and abut against the hammer handle 312. Through the above arrangement, the guiding function of the tamping hammer 31 can also be satisfied.

[0051] Optionally, a limiting groove may be provided on the peripheral side of the guide wheel or the guide plate, and the hammer handle 312 is embedded in the limiting groove, and the limiting groove can effectively limit the hammer handle 312 .

[0052] In some embodiments, the guide assembly 321 may further include a guide rail and a slider movably connected to each other, the guide rail extends along the first direction X, one of the guide rail and the slider is disposed on the support assembly 32 and the other is disposed on the hammer handle 312 .

[0053] A coal briquette tamping machine provided in an embodiment of the present application, wherein the guide assembly 321 adopts the above-mentioned form, can also satisfy the guiding function of the tamping hammer 31. At the same time, by providing a guide rail and a slider, the wear of the multi-frame and the tamping hammer 31 can be reduced during the movement of the tamping hammer 31 along the first direction, and the service life of the coal briquette tamping machine can be increased by means of a better guide rail and / or slider.

[0054] In some embodiments, the briquettes compacting machine further comprises a display connected to the counting component 4 and configured to display the statistical value of the number of times.

[0055] In one embodiment of the present application, a coal cake tamping machine is provided with a display to facilitate operators to view the statistical value of the number of times. Optionally, the display is a plasma display or a liquid crystal display.

[0056] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
