Abstract
The utility model provides a colliery is coal pillar grading breaker in pit, includes coal sample jar (1) and installs power supply (2) in coal sample jar (1) below, the pan feeding mouth is connected at the top of coal sample jar (1), the power output shaft who connects power supply (2) behind coal sample jar (1) is run through to the bottom of setting transfer line (3) in coal sample jar (1) to by lower up installing blade (4), spacing frame (5) and drill bit (6) in proper order on transfer line (3). The utility model relates to a hierarchical broken mode solves the problem that starts the difficulty after broken jar stopper goes into the coal column, and after the coal sample got into the coal sample jar by the pan feeding mouth, adopt the drill bit to carry out the one-level processing of breaking to the coal column, recycle spacing frame and carry out the secondary breakage to the coal column that breaks, the coal column after the secondary breakage was leaked the net through the bottom of spacing frame and is come blade department, carries out the third time breakage, has improved the crushing efficiency of coal column.
Description
Technical Field
The utility model relates to a coal pillar breaker specifically is a colliery is coal pillar grading breaker in pit belongs to coal pillar breaker technical field.
Background
At present, a deep hole fixed-point sampling drilling machine is generally used for sampling to measure the gas content in a coal mine, but the collected sample is a coal pillar with a larger size, the existing crushing mode is difficult to crush the large-size coal pillar, and the crushed particle size cannot meet the requirement.
Disclosure of Invention
Problem to above-mentioned prior art exists, the utility model provides a colliery is coal pillar grading breaker in pit, simple structure can solve broken jar and fill in the problem of starting the difficulty behind the coal pillar, can also improve crushing efficiency for the particle diameter after the breakage reaches the requirement.
In order to achieve the purpose, the utility model provides a colliery is coal pillar grading breaker in pit, including the coal sample jar with install the power supply in coal sample jar below, the pan feeding mouth is connected at the top of coal sample jar, the power output shaft who connects the power supply behind the coal sample jar is run through to the bottom of the transfer line of setting in the coal sample jar to by bottom up installing blade, spacing frame and drill bit in proper order on the transfer line.
In order to improve the crushing efficiency and the degree of the first order of coal column, the utility model discloses a drill bit comprises the broken head of toper, can effectually carry out the first order breakage to the coal column.
In order to improve the crushing efficiency and the degree of pillar second grade, the utility model discloses a spacing frame comprises the vertical blade that encircles around with the hourglass net of bottom, can effectually carry out the second grade breakage to the pillar.
In order to improve the crushing efficiency and the degree of the pillar third level, the utility model discloses a blade sets up to two sets of, can effectually carry out the third level breakage to the pillar.
In order to provide stable power output for breaker, the utility model discloses a power supply sets up to motor or air motor.
Compared with the prior art, the utility model relates to a hierarchical broken mode solves the problem that starts the difficulty after broken jar stopper goes into the coal column, and after the coal sample got into the coal sample jar by the pan feeding mouth, adopt the drill to carry out the one-level processing of breaking to the coal column, recycle spacing frame and carry out the secondary breakage to the coal column that breaks, the coal column after the secondary breakage leaked the net through the bottom of spacing frame and comes blade department, carries out the third time breakage, has improved the crushing efficiency of coal column.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the position limiting frame of fig. 1.
In the figure: 1. coal sample jar, 2, power supply, 3, transfer line, 4, blade, 5, spacing frame, 6, drill bit.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the coal pillar grading and crushing device for the underground coal mine comprises a coal sample tank 1 and a power source 2 arranged below the coal sample tank 1, wherein the power source 2 is a motor or a pneumatic motor; the top of the coal sample tank 1 is connected with a feeding port, the bottom end of a transmission rod 3 arranged in the coal sample tank 1 penetrates through the coal sample tank 1 and then is connected with a power output shaft of a power source 2, a blade 4, a limiting frame 5 and a drill bit 6 are sequentially arranged on the transmission rod 3 from bottom to top, and the drill bit 6 is composed of a conical crushing head and can perform primary crushing on a coal column; as shown in fig. 2, the limiting frame 5 is composed of a leakage net at the bottom and vertical blades surrounding the leakage net, and can perform secondary crushing on the coal pillar; the blades 4 are arranged into two groups, and can be used for carrying out third-stage crushing on the coal pillar.
The utility model discloses when using, the coal pillar gets into from the pan feeding mouth, is provided power by power supply 2, and power supply 2 drives transfer line 3 and rotates to make blade 4, spacing frame 5, the rotatory broken operation that carries out of drill bit 6. After the coal pillar got into coal sample jar 1, at first broken by drill bit 6 and handled, carry out the breakage for the first time, the coal pillar after the drill bit breakage carries out the secondary breakage through spacing frame 5's vertical blade, and the coal pillar after the secondary breakage leaks the net through spacing frame 5's bottom, carries out the third time breakage through blade 4 at last, the utility model discloses simple structure adopts hierarchical broken mode, has solved the problem that starts the difficulty after broken jar stopper income coal pillar to crushing efficiency has been improved.
