The parts that are not described in detail in the following embodiments of the present invention, such as the other end of the baffle rod hinged at the end of the upper arc ring being pressed against the inner wall of the other end of the upper arc ring through a torsion spring arranged between the baffle rod and the upper arc ring to close the gap, the upper telescopic rod sliding through the lower telescopic rod to extend or shorten the length of the handheld upright pole, etc., should all be immediately known to those skilled in the art or should be known to the prior art.
[0023] like Figure 1-2 As shown, a portable, hands-free coal powder extraction tool comprises a hand-held upright pole 2 and a powder extraction hanging funnel 1, wherein the powder extraction hanging funnel 1 is mounted on the top of the hand-held upright pole 2. The powder extraction hanging funnel 1 comprises an upper arc ring 103, a lower ring opening 107 and three connecting rods 102, wherein the three connecting rods 102 are arranged at intervals between the upper arc ring 103 and the lower ring opening 107, and the lower ring opening 107 and the upper arc ring 103 are connected by the three connecting rods 102. An intermediate connecting arc ring 101 is hooped between the three connecting rods 102, and the intermediate connecting arc ring 101 is arranged at an upper middle position of the three connecting rods 102. The three connecting rods 102 can maintain the stability of the spacing between the adjacent connecting rods 102 through the fixation of the intermediate connecting arc ring 101, and the upper arc ring 103, the intermediate connecting arc ring 101 and the plurality of connecting rods 102 are all made of steel.
[0024] The powder collecting hanging funnel 1 is screwed to the upper end of the hand-held upright pole 2 through the lower connecting ring opening 107, the inner wall of the lower connecting ring opening 107 is provided with an internal thread, and the outer periphery of the upper end of the hand-held upright pole 2 is provided with an external thread, and the powder collecting hanging funnel 1 is screwed to the hand-held upright pole 2 through the lower connecting ring opening 107. The outer peripheral cover between the upper arc ring 103 and the lower connecting ring opening 107 is provided with a wind tube cloth 109, and the wind tube cloth 109 is enclosed to form the powder collecting hanging funnel 1 capable of collecting coal powder.
[0025] A notch 105 is provided at the left side of the upper arc ring 103. A blocking rod 104 is hingedly connected to the lower end of the upper arc ring 103 at the notch 105. The end of the blocking rod 104 connected to the lower end of the upper arc ring 103 is a movable end, and the end of the blocking rod 104 away from the lower end of the upper arc ring 103 is a free end. Figure 3As shown, the blocking rod 104 can rotate toward the upper arc ring 103 with the lower end as the center. A torsion spring 108 is arranged between the movable end of the blocking rod 104 and the lower end of the upper arc ring 103, the left end of the torsion spring 108 abuts against the blocking rod 104, and the right end of the torsion spring 108 abuts against the inner wall of the upper arc ring 103.
[0026] The torsion spring 108 is provided to make the free end of the blocking rod 104 abut against the inner side wall of the upper end of the upper arc ring 103, so that the gap 105 is usually closed in a normal state. The tool needs to be hung with the crossbeam 3 arranged near the sampling opening, and the blocking rod 104 can open the gap 105 under the push of the crossbeam 3 arranged on one side of the sampling opening, so that the crossbeam 3 is connected to the arc ring 103, and then the tool is hung on the crossbeam 3 through the upper arc ring 103, which reduces the fatigue of the workers who hold the tool for a long time during coal mining, and the instability, tilting and falling of coal, which greatly reduces the labor intensity of the workers.
[0027] The free end of the blocking rod 104 is connected to a pull rope 106, and a through hole (not shown in the figure) is provided on the lower side of the upper arc ring 103 at the position where the right end of the blocking rod 104 contacts it when it swings to the limit. The left end of the pull rope 106 is fixed to the blocking rod 104, and the other end of the pull rope 106 is arranged along the hand-held upright pole 2 after passing through the through hole. In addition, positioning hoops (not shown in the figure) are respectively arranged on the outer side walls of the upper end and the lower end of the hand-held upright pole 2. A plurality of positioning hoops are distributed along the axial direction of the hand-held upright pole 2, and one end of the pull rope 106 passing through the through hole is sequentially arranged through the positioning hoop. The arrangement of the positioning hoop can make the pull rope 106 distributed along the axial direction of the hand-held upright pole 2 play a role of storage, and can also facilitate the staff to pull the blocking rod 104 to rotate and open the gap 105 by pulling the pull rope 106 after the powder is taken. The tool can be quickly removed from the crossbeam 3 through the pull rope 106 to facilitate the subsequent detection of the methane content.
[0028] like Figure 1 As shown, the hand-held upright pole 2 is a circular tube with a hollow interior and can be retracted. The retractable hand-held upright pole 2 can be extended to mine pulverized coal, and can also be shortened for easy carrying. The hand-held upright pole 2 includes a lower telescopic tube 203 and an upper telescopic tube 201 inserted into the lower telescopic tube 203. The upper telescopic tube 201 and the lower telescopic tube 203 are arranged in sequence from top to bottom, wherein the bottom of the lower telescopic tube 203 is sealed. An external thread is provided on the outer periphery of the upper port of the upper telescopic tube 201, and the powder extraction hanging funnel 1 screwed to the upper telescopic tube 201 is connected to the upper telescopic tube 201. When extracting coal powder, the coal powder can enter the inner cavity of the hand-held upright pole 2 through the powder extraction hanging funnel 1, reducing the contact between the coal powder and the air, thereby reducing the problem of methane content measurement accuracy that may be caused by the long contact time between the coal powder and the air.
[0029] In addition, the outer circumference of the lower telescopic tube 203 has scale lines (not shown in the figure), and the scale lines are arranged along the axial direction of the lower telescopic tube 203. The lower telescopic tube 203 has a bar hole (not shown in the figure), which is located on one side of the scale line and arranged along the axial direction of the lower telescopic tube 203. The lower end of the upper telescopic tube 201 is provided with a scale indicator needle 202, which passes through the bar hole.
[0030] Since the height of the underground tunnel of the coal mine is usually 4.5m, the scale lines on the outer periphery of the lower telescopic tube 203 are 0 to 4m from bottom to top. In addition, a vertical rod 2041 is hinged at the bottom of the lower telescopic tube 203, and the vertical rod 2041 can rotate 360° around the bottom of the lower telescopic tube 203. A hook 204 is provided at one end of the vertical rod 2041 away from the lower telescopic tube 203, and the tool can be hung on the side wall of the coal mine by the hook 204 when not in use to achieve storage.
[0031] The specific implementation of the utility model is as follows: First, the staff adjusts the extended hand-held pole 2 according to the height of the corresponding sampling opening. The staff holds the extended hand-held pole 2 and drives the baffle 104 on the powder collection hanging funnel 1 to contact the crossbeam 3 through the hand-held pole 2. The baffle 104 rotates to open the gap 105 under the push of the crossbeam 3. After the crossbeam 3 enters the upper arc ring 103, the baffle 104 rotates to close the gap 105 under the action of the torsion spring 108. After the tool is hung on the crossbeam 3, the staff fine-tunes the position of the powder collection hanging funnel 1 by adjusting the position of the hand-held pole 2 until the powder collection hanging funnel 1 is aligned with the sampling opening. When the sampling is completed, the staff holds the hand-held pole 2 with one hand and pulls the pull rope 106 with the other hand to drive the baffle 104 to rotate to open the gap 105. After the crossbeam 3 is out of the upper arc ring 103, the tool is removed and shortened for subsequent methane detection.
