Description

Crucibleless automatic conveying equipment for bituminous coal

technical field

The invention relates to the field of automatic equipment for bituminous coal testing, and is mainly used in the crucible-free conveying of bituminous coal samples, in particular to a crucible-free automatic conveying equipment for bituminous coal.

Background technique

In the field of automatic testing of bituminous coal, it is often necessary to pour the coal sample in one crucible into another nearby crucible to test the transportation of the coal sample. In the traditional technique, the operator takes a crucible A containing a bituminous coal sample, walks to another crucible B, pours the bituminous coal into another crucible B, and finally puts the crucible A back to its original place. The process of transporting coal samples is all manual operation, the labor intensity of workers is high, the working environment is harsh, and human errors are large.

Contents of the invention

The technical problem to be solved by the present invention is: in view of the problems of high labor intensity in the prior art, the present invention provides a crucible-free transport of bituminous coal samples from one point A to another point B, which has a compact structure and does not require manual participation. .

In order to solve the above problems, the solution proposed by the present invention is: a crucible-free automatic conveying equipment for bituminous coal, which includes a hollow moving frame, a hopper installed at the left end of the hollow moving frame, and a hopper installed inside the hollow moving frame The guide frame, the thread combination shaft installed inside the hopper guide frame, and the stepping motor; the hollow moving frame first makes a linear motion and then rotates under the joint action of the thread combination shaft and the hopper guide frame, thereby driving the hopper to achieve a straight line. Movement and flipping functions.

The axes of the hollow mobile frame, the hopper guide frame and the threaded combined shaft of the present invention coincide with each other; the hollow mobile frame includes a hollow outer boss and a mobile main frame; one end of the mobile main frame is provided with a hollow outer boss outside, The interior of the other end is provided with internal thread; the interior of the hollow outer boss is hollow, and steel balls, compression springs and screws are installed from bottom to top; the hopper guide frame includes a guide main frame, a guide frame chute and a guide frame round table The guide frame chute is composed of a section of straight line chute and a section of curved chute, which are respectively used for linear motion guidance and automatic flipping guidance of the hopper; the thread combination shaft is composed of a combination shaft screw, a combination shaft main shaft and a combination shaft optical axis Composition: the combination shaft screw is installed outside the hopper guide frame and inside the hollow moving frame.

Compared with the prior art, the advantage of the present invention is that: the crucible-free automatic conveying equipment for bituminous coal of the present invention is equipped with a hollow moving frame, a hopper guide frame and a thread combination shaft, which can control the shape movement of the hopper along the guide frame chute to realize Linear motion and automatic flipping process. It can be seen that the present invention has a simple structure and no human intervention, can realize crucible-free transportation of bituminous coal samples, reduces labor intensity, and improves the transportation efficiency of bituminous coal samples.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 , the optical axis 43 of the combined shaft is connected with the stepping motor 9 , and the rotation of the stepping motor 9 drives the threaded combined shaft 4 to rotate synchronously.

The upper end of the steel ball 5 inside the hollow outer boss 22 of the hollow mobile frame 2 is pressed by the compression spring 6, and the lower end is located in the guide frame chute 32 of the hopper guide frame 3, and the steel ball 5 can only roll in the guide frame chute 32; The first section of the guide frame chute 32 is a linear chute, and the last section is a half-circumferential chute, so the hopper 1 starts to make a linear motion, and then performs a turning motion.

The combination shaft screw rod 41 is engaged with the internal thread of the moving main body frame 21, and the screw transmission is realized between the thread combination shaft 4 and the hollow moving frame 2.

Working process: first pour the coal sample into the hopper 1, then start the stepping motor 9, the stepping motor 9 drives the thread combination shaft 4 to rotate forward, the steel ball 5 first rolls in the linear chute of the guide frame chute 32, and the hopper 1 move away from the stepper motor 9 to the target position; the stepper motor 9 continues to rotate forward, the steel ball 5 rolls in the circumferential curved chute of the guide frame chute 32, and the hopper 1 begins to turn over above the target position, turning Pour out the coal sample at 180 degrees; after pouring out the coal sample, the stepper motor 9 rotates in the reverse direction, the steel ball 5 rolls in the reverse direction in the circumferential curved chute of the guide frame chute 32, and the hopper 1 reverses over the target position Get back to the normal state; the stepper motor 9 continues to rotate in reverse, the steel ball 5 reversely moves in the linear chute of the guide frame chute 32, and the hopper 1 moves backward, thereby completing a process of automatically transporting bituminous coal without a crucible.
