[0039] Figure 1 This is a front view of a device for measuring volatile matter of coal provided by an embodiment of the utility model; Figure 2 It is a structural schematic diagram of a combined drive mechanism provided by an embodiment of the utility model; Figure 3 It is a front view of the combined drive mechanism provided by the embodiment of the utility model.

[0040] See also Figures 1 to 3 An embodiment of the utility model provides a combined driving mechanism, which includes a mounting seat body 10, a first driving mechanism 20 and a second driving mechanism 30.

[0041] The mounting base body 10 serves as a mounting carrier for the first driving mechanism 20 and the second driving mechanism 30. The mounting base body 10 includes a base 11 with a rectangular structure and a first supporting portion 12 and a second supporting portion 13 vertically arranged on the base 11, that is, the base 11 is arranged in a horizontal direction, and the first supporting portion 12 and the second supporting portion 13 are arranged in a vertical direction, and the first supporting portion 12 and the second supporting portion 13 are arranged in parallel and spaced apart.

[0042] The base 11, the first support part 12 and the second support part 13 may be integrally formed; the base 11 and the first support part 12 may be integrally formed, and the second support part 13 may be detachably connected to the base 11 by bolts, screws and other structures; the first support part 12 and the second support part 13 may be detachably connected to the base 11 by bolts, screws and other structures. A furnace body part 40 is provided on the first support part 12 and the second support part 13, and the furnace body part 40 is used to volatilize the coal sample.

[0043] The first driving mechanism 20 includes a driving component 21 and a first transmission component 22. The first transmission component 22 is suitable for connecting to a sample delivery component 23. The driving component 21, the first transmission component 22 and the sample delivery component 23 are all arranged on the first support portion 12 of the mounting base body 10, and the driving component 21, the first transmission component 22 and the sample delivery component 23 are all located below the furnace body part 40.

[0044] The first transmission assembly 22 is disposed on the first support portion 12 of the mounting base 11, the sample delivery assembly 23 is disposed on the first transmission assembly 22, and the driving assembly 21 is connected to the first transmission assembly 22, and is suitable for driving the first transmission assembly 22 to perform lifting motion along a straight line, so that the first transmission assembly 22 drives the sample delivery assembly 23 to perform lifting motion toward the furnace body component 40 to deliver the sample;

[0045] The second driving mechanism 30 includes a second transmission assembly 32, which is suitable for connecting to the furnace door assembly 31. The second transmission assembly 32 is connected to the first transmission assembly 22 and is suitable for moving with the first transmission assembly 22 to drive the furnace door assembly 31 to open or close.

[0046] It can be understood that the combined driving mechanism provided in the embodiment of the utility model connects the second transmission component 32 of the second driving mechanism 30 with the first transmission component 22. When the driving component 21 drives the first transmission component 22 to perform lifting and lowering movements along a straight line, so that the first transmission component 22 drives the sample delivery component 23 to move toward the furnace body part 40 for sample delivery, the second transmission component 32 is connected to the first transmission component 22 and can move with the first transmission component 22 to drive the furnace door component 31 to open or close.

[0047] This is equivalent to combining the first transmission component 22 that directly drives the movement of the sample delivery component 23 with the second transmission component 32 that directly drives the opening and closing of the furnace door component 31. The movement of the two transmission components is controlled simultaneously by one driving component 21, so that the sample delivery component 23 and the furnace door component 31 run synchronously. This not only simplifies the structure and control logic, but also eliminates the control structure and detection structure separately set for the furnace door component 31, so as to prevent the furnace body component 40 from affecting the control structure and detection structure separately set for the furnace door component 31, thereby improving the overall reliability and stability of the device.

[0048] Furthermore, the synchronous operation of the sample delivery component 23 and the furnace door component 31 can shorten the opening time of the furnace door component 31 and accurately control the volatilization temperature of the furnace body component 40 .

[0049] Continue reading Figures 1 to 3 In some embodiments of the utility model, the first transmission component 22 includes a first sliding element 221, a guide element 222 and a transmission element 223; the guide element 222 is fixedly arranged on the mounting seat body 10, the transmission element 223 is rotatably arranged on the mounting seat body 10, the transmission element 223 is connected to the driving component 21, the first sliding element 221 and the guide element 222 are slidably matched, the first sliding element 221 and the transmission element 223 are transmission matched, and the sample delivery component 23 is arranged on the first sliding element 221.

[0050] When the driving component 21 works to drive the transmission element 223 to rotate, so that the first sliding element 221 moves along the guide element 222, the first sliding element 221 drives the sample delivery component 23 to move up and down along a straight line, so that the sample delivery component 23 can be switched between the sample delivery position and the sample injection position. When the sample delivery component 23 is located at the sample delivery position, it is equivalent to the sample delivery component 23 being located inside the furnace body part 40. When the sample delivery component 23 is located at the sample injection position, it is equivalent to the sample delivery component 23 being located outside the furnace body part 40, that is, the sample delivery component 23 is away from the furnace body part 40. At this time, samples can be added to the sample delivery component 23.

[0051] Specifically, the first sliding element 221 can be a structure such as a slider, and other structures that can not only slide with the guide element 222 but also can be transmission-coordinated with the transmission element 223 and have installation and bearing functions are also possible.

[0052] The guide element 222 can be a guide rail or a track. The guide element 222 is detachably connected to the first support portion 12 of the mounting seat body 10 by fasteners such as bolts, and is arranged along the height direction of the first support portion 12. The guide element 222 is used to provide a guiding function for the first sliding element 221.

[0053] The transmission element 223 can be a lead screw or a lead screw. The transmission element 223 is installed on the first support portion 12 of the mounting seat body 10 through a bearing or other structures. The transmission element 223 is connected to the driving assembly 21 through a spline or a coupling, and the first sliding element 221 is threadedly matched with the transmission element 223. When the driving assembly 21 is working, the driving transmission element 223 is rotated to drive the first sliding element 221 to move synchronously. Since the first sliding element 221 is restricted by the guide element 222, it can only perform a linear lifting motion along the guide element 222, thereby realizing the lifting and moving of the lifting sample feeding assembly 23.

[0054] Equivalently, the first transmission component 22 may be a screw-nut pair structure, the driving component 21 may be a motor or other driving device, and the motor may be connected to the transmission element 223 via gears or via structures such as belts.

[0055] In addition, the first transmission component 22 can also include a first sliding element 221 and a guide element 222. The first sliding element 221 is a structure such as a slider, and the guide element 222 is a guide rod. The first sliding element 221 and the guide element 222 are slidably matched, and the guide element 222 provides guidance for the first sliding element 221. The driving component 21 can be a linear drive such as a cylinder.

[0056] Continue reading Figure 3 In some embodiments of the utility model, the second transmission assembly 32 includes a second sliding element 321, and the second sliding element 321 is located on the back side of the first support portion 12 of the mounting seat body 10, that is, the second sliding element 321 is located on the side away from the guide element 222, and the second sliding element 321 is slidably matched with the first support portion 12 of the mounting seat body 10 so that the second sliding element 321 can reciprocate along the width direction of the first support portion 12 under the action of external force.

[0057] The oven door assembly 31 is connected to the second sliding element 321 , and is adapted to reciprocate along the width direction of the first support portion 12 under the action of the second sliding element 321 to achieve opening or closing.

[0058] The second sliding element 321 is provided with a preset track groove 322 , and the first sliding element 221 is provided with a toggle member 224 matched with the preset track groove 322 .

[0059] When the driving component 21 is working and the driving transmission element 223 is rotated to drive the first sliding element 221 to move synchronously, the toggle member 224 provided on the first sliding element 221 reciprocates along a straight line to drive the second sliding element 321 to reciprocate along the width direction of the first support portion 12, thereby driving the furnace door component 31 to reciprocate along the width direction of the first support portion 12 to achieve opening or closing.

[0060] Figure 4 It is a structural schematic diagram of the second sliding element 321 in the combined driving mechanism provided in an embodiment of the utility model.

[0061] See also Figure 4 It can be known that on one side surface of the second sliding element 321 facing the first support portion 12, a preset trajectory groove 322 composed of multiple sections of sliding grooves is formed inwardly recessed, and the toggle member 224 is inserted in the preset trajectory groove 322 and can move along the preset trajectory groove 322. Since the position of the first sliding element 221 in the width direction of the first support portion 12 remains unchanged, the position of the toggle member 224 arranged on the first sliding element 221 remains unchanged. When the toggle member 224 moves along the preset trajectory groove 322, it can toggle the second sliding element 321 to move along the width direction of the first support portion 12.

[0062] The preset track groove 322 includes a first track segment 3221, a second track segment 3222 and a third track segment 3223 which are interconnected. The first track segment 3221 and the third track segment 3223 are staggered, and the second track segment 3222 is obliquely connected between the first track segment 3221 and the third track segment 3223.

[0063] When the oven door assembly 31 is in an open state, the toggle member 224 is located at the first track segment 3221, and when the oven door assembly 31 is in a closed state, the toggle member 224 is located at the third track segment 3223. Since the oven door assembly 31 needs to be kept in a closed or open state when the toggle member 224 is located at the first track segment 3221 or the third track segment 3223, the first track segment 3221 and the third track segment 3223 both extend in the vertical direction, and the first track segment 3221 and the third track segment 3223 are not on the same straight line.

[0064] The second track segment 3222 is obliquely connected between the first track segment 3221 and the third track segment 3223, which can reduce the resistance of the toggle member 224 switching from the first track segment 3221 to the third track segment 3223, improve the smoothness of the furnace door assembly 31 when switching from the open state to the closed state, and avoid the toggle member 224 from getting stuck when moving in the preset track groove 322.

[0065] Continue reading Figure 4In some embodiments of the present invention, the preset track groove 322 further includes a fourth track segment 3224 and a fifth track segment 3225 that are interconnected. The fifth track segment 3225 is connected to the starting end of the first track segment 3221. The fifth track segment 3225 is tilted, and the tilt direction of the fifth track segment 3225 is opposite to the tilt direction of the second track segment 3222. The fourth track segment 3224 and the third track segment 3223 are located on the same straight line, that is, the fourth track segment 3224 and the third track segment 3223 are coaxially arranged.

[0066] When the furnace door assembly 31 is in an open state, the toggle member 224 is located at the first track segment 3221, and when the furnace door assembly 31 is in a closed state, the toggle member 224 is located at the third track segment 3223 or the fourth track segment 3224. This is equivalent to the toggle member 224 being at both ends of the preset track groove 322, and the furnace door assembly 31 is in a closed state. Only when the toggle member 224 is located at the middle position of the preset track groove 322, the furnace door assembly 31 is opened to allow the sample delivery assembly 23 to pass through and enter the furnace body component 40.

[0067] Figure 5 It is a schematic diagram of the cooperation between the first sliding element 221 and the second sliding element 321 in the combined driving mechanism provided in an embodiment of the utility model.

[0068] Continue reading Figure 3 , and also see Figure 5 In some embodiments of the utility model, a sliding groove 323 is provided on either the second sliding element 321 or the first supporting portion 12 of the mounting seat body 10, and the sliding groove 323 is arranged along the width direction of the second sliding element 321 or the first supporting portion 12; a sliding block 121 matching the sliding groove 323 is provided on the other one of the second sliding element 321 and the first supporting portion 12.

[0069] That is, a sliding groove 323 can be set on the second sliding element 321, and a sliding block 121 that slides in cooperation with the sliding groove 323 can be set on the first support portion 12; or a sliding groove 323 can be set on the first support portion 12, and a sliding block 121 that slides in cooperation with the sliding groove 323 can be set on the second sliding element 321.

[0070] The sliding groove 323 and the slider 121 are assembled to form a slider guide structure, which can provide installation and connection functions for the second sliding element 321 and the first support portion 12 of the mounting seat body 10, and can also meet the requirements of the second sliding element 321 to perform linear reciprocating motion along the first support portion 12. Therefore, the sliding groove 323 can also be replaced by a sliding rail or a guide rail, and the slider 121 can also be replaced by a ball or a roller.

[0071] It should be noted that when the position of the second sliding element 321 corresponds to the position of the oven door assembly 31, the oven door assembly 31 can be directly connected to the second sliding element 321, so that the second sliding element 321 drives the oven door assembly 31 to open or close. When there is a deviation between the position of the second sliding element 321 and the position of the oven door assembly 31, a linkage rod 33 can be fixedly arranged on the second sliding element 321, so that the second sliding element 321 is indirectly connected to the oven door assembly 31 through the linkage rod 33. Therefore, the setting of the linkage rod 33 can be adaptively adjusted according to actual use conditions, and it is not a necessary structure.

[0072] Continue reading Figure 1 The embodiment of the utility model also provides a coal volatile matter measuring device, including a sample delivery component 23, a furnace door component 31, a furnace body component 40 and any one of the combined driving mechanisms; the sample delivery component 23 is arranged on the first transmission component 22, the furnace door component 31 is arranged on the second transmission component 32, and the furnace body component 40 is arranged on the mounting seat 10 and is located above the furnace door component 31.

[0073] This is equivalent to the combined driving mechanism provided in the embodiment of the utility model being applied to a coal volatile content measuring device. Of course, the combined driving mechanism provided in the embodiment of the utility model can also be applied to other products.

[0074] Figure 6 It is a top view of the combined drive mechanism provided in the embodiment of the utility model.

[0075] See also Figure 3 , and also see Figure 6 In some embodiments of the utility model, the oven door assembly 31 includes an oven door component 311, a guide component 312 and a pusher 313. The guide component 312 is fixed to the first support portion 12 of the mounting seat body 10. The oven door component 311 and the guide component 312 are slidably matched. The pusher 313 is provided with a guide groove along the length direction. The oven door component 311 is provided with a matching component, which is inserted into the guide groove and is suitable for moving along the guide groove and driving the oven door component 311 to move to achieve opening or closing.

[0076] The furnace door component 311 can be a single door or multiple doors of a flat opening type. When the furnace door component 311 is a multiple door of a flat opening type, the multiple doors can be opened and closed with equal distances or with variable distances. In addition, the furnace door component 311 can open and close along a straight line or along a curve, and the specific opening and closing method depends on the shape of the guide groove.

[0077] When the oven door component 311 is in an open state, the toggle member 224 is located at the first track segment 3221, and the matching member is located at the first end of the guide groove; when the oven door component 311 is in a closed state, the toggle member 224 is located at the third track segment 3223, and the matching member is located at the second end of the guide groove away from the first end.

[0078] Since the opening time of the furnace door component 311 is determined by the length of the first track segment 3221, the length of the first track segment 3221 can be adjusted as needed. The opening time of the furnace door component 311 can also be effectively shortened by adjusting the spacing between the first track segment 3221 and the third track segment 3223 along the width direction of the second sliding element 321, that is, adjusting the length of the second track segment 3222; in addition, the duration of the furnace door component 311 being in the closed state can also be effectively shortened by adjusting the lengths of the third track segment 3223 and the fourth track segment 3224.

[0079] Therefore, the embodiment of the utility model can shorten the time that the furnace door component 311 is in the open state or the closed state by reasonably setting the length of each track segment in the preset track groove 322, which is beneficial for the coal volatile matter measuring device to accurately control the volatilization temperature.

[0080] It should be noted that the guide component 312 may be a slide rail or a track, and the guide component 312 is used to provide a guide for the furnace door component 311 .

[0081] Figure 7 It is a structural schematic diagram of the pushing member 313 in the combined driving mechanism provided in an embodiment of the utility model.

[0082] Continue reading Figure 6 , and also see Figure 7 In some embodiments of the utility model, the furnace door component 311 includes a first door body 3111 and a second door body 3112 which are arranged opposite to each other. The first door body 3111 and the second door body 3112 are both slidably matched with the guide component 312, that is, the furnace door component 311 is a double-opening furnace door structure.

[0083] The structure of the pusher 313 is adapted to the structure of the furnace door component 311. The pusher 313 includes a first pusher portion 3131 and a second pusher portion 3132 connected to each other. The first pusher portion 3131 and the second pusher portion 3132 are arranged at an angle to each other. The first pusher portion 3131 is provided with a first guide groove 3133, and the second pusher portion 3132 is provided with a second guide groove 3134. The first door body 3111 is provided with a first matching piece 3113 matched with the first guide groove 3133, and the second door body 3112 is provided with a second matching piece 3114 matched with the second guide groove 3134. The distance between the first end of the first guide groove 3133 and the first end of the second guide groove 3134 is smaller than the distance between the second end of the first guide groove 3133 and the second end of the second guide groove 3134.

[0084] When the furnace door component 311 is in the open state, the toggle member 224 is located at the first track section 3221, the first door body 3111 and the second door body 3112 are close to or abut against each other, the first matching member 3113 is located at the first end of the first guide groove 3133, and the second matching member 3114 is located at the first end of the second guide groove 3134.

[0085] When the furnace door component 311 is in a closed state, the toggle member 224 is located at the third track segment 3223 or the fourth track segment 3224, the first door body 3111 and the second door body 3112 are away from each other, the first matching member 3113 is located at the second end of the first guide groove 3133, and the second matching member 3114 is located at the second end of the second guide groove 3134.

[0086] It should be noted that both the first door body 3111 and the second door body 3112 are provided with avoidance gaps for the sample delivery push rod 231 to pass through. Through the avoidance gaps, the first door body 3111 and the second door body 3112 can avoid the sample delivery push rod 231, and the two relatively arranged door bodies abut against each other, thereby achieving a better blocking effect.

[0087] Continue reading Figure 2 , Figure 3 and Figure 6 In some embodiments of the present invention, the sample delivery assembly 23 includes a sample delivery push rod 231 and a material container 232. The sample delivery push rod 231 is fixed on the first sliding element 221, and the material container 232 is fixed on the sample delivery push rod 231. The first sliding element 221 moves to drive the sample delivery push rod 231 to move, so that the material container 232 enters the furnace body part 40 or is located outside the furnace body part 40 to hold the sample. The material container 232 can be a crucible.

[0088] In some embodiments of the present invention, the furnace body component 40 may be a heating furnace having a radiation cavity and an opening communicating with the radiation cavity. The furnace door assembly 31 is located at the opening of the furnace body component 40 for opening or closing the opening.

[0089] The coal volatile content measuring device provided by the embodiment of the utility model, during operation, adds a weighed sample to the material container 232, then controls the driving component 21 to start, and the driving component 21 drives the transmission component 223 to rotate, so that when the first sliding component 221 moves along the guide component 222, the first sliding component 221 drives the sample delivery component 23 to move up and down in the height direction, and at the same time, the furnace door component 311 is synchronously operated to open, so that the material container 232 enters the furnace body component 40, and then the furnace door component 311 is synchronously operated to close, and the sample in the material container 232 is volatilized in the furnace body component 40. After the volatilization is completed, the furnace door component 311 is opened, and at the same time, the first sliding component 221 drives the sample delivery component 23 to descend in the height direction to leave the furnace body component 40.

[0090] The coal volatile matter measuring device provided in the embodiment of the utility model connects the second transmission component 32 of the second driving mechanism 30 with the first transmission component 22. When the driving component 21 drives the first transmission component 22 to move up and down along a straight line, so that the first transmission component 22 drives the sample delivery component 23 to move toward the furnace body part 40 for sample delivery, the second transmission component 32 is connected to the first transmission component 22 and can move with the first transmission component 22 to drive the furnace door component 31 to open or close.

[0091] This is equivalent to combining the first transmission component 22 that directly drives the sample delivery component 23 to move, and the second transmission component 32 that directly drives the furnace door component 31 to open and close, and controlling the movement of the two transmission components simultaneously through one driving component 21, so that the sample delivery component 23 and the furnace door component 31 operate synchronously. This arrangement can save the furnace door component 311 from separately setting a mechanism for controlling the opening and closing and a detection element for detecting the opening and closing state, which can not only simplify the structure and control logic, but also effectively reduce the failure rate of the coal volatile content measuring device and improve the reliability and stability of the coal volatile content measuring device.
