The upper part (except the photoelectric speedometer and the laser range finder) of the supporting bottom plate of the invention is of a bilateral symmetry structure, the functional principle and the connecting and fixing mode are the same, so that the left mechanism is taken as an example for introduction:
the lower surfaces of the first left support column 4 and the second left support column 14 are fixedly connected with the first support bottom plate 1 and the second support bottom plate 5 respectively, and the vertical height of the left pushing baffle plate 18 is controlled by the two support columns together, so that the left pushing baffle plate 18 is required to synchronously extend or retract, and the lower surface of the left pushing baffle plate 18 is always kept in a horizontal state. The lower end of the left supporting upright post 4 is fixedly connected with the first supporting bottom plate 1, and the upper end of the left supporting upright post is hinged with the front end cylinder of the left pushing baffle 18 (namely, a shaft sleeve structure), so that the front end of the left pushing baffle 18 can freely rotate around the upper end of the left supporting upright post 4. The lower surface of the left support plate 15 is fixedly connected with the upper surface (top end) of the left two support columns 14, and the function of the left support plate is to provide a support base for the left ear plate 16. The lower surface of left otic placode 16 is fixed with left supporting plate 15, and the right flank surface of left otic placode 16 is fixed with the stiff end of left side pole 17 of advancing, provides the holding surface for left side pole 17 of advancing. One end (fixed end) of the left pushing rod 17 is fixedly connected with the left ear plate 16, the other end of the left pushing rod is fixedly connected with the rear end of the left pushing baffle 18, and the pushing-out and the pulling-back of the rear end of the left pushing baffle 18 can be controlled along with the stretching-out and the retracting-back of the left pushing rod 17.
The left pushing plate 18, the left pushing rod 17, the right pushing plate 13, and the right pushing rod 12 constitute a pushing mechanism of the present invention.
In the invention, the left pushing baffle 18 and the right pushing baffle 13 are both arc-shaped, so that materials can pass through between the left pushing baffle 18 and the right pushing baffle 13 in the process of pushing the materials, and the normal transportation of the materials is not influenced.
The four support uprights 3, 4, 9, 14 and the two pusher rods 12, 17 in the present invention can be hydraulic or pneumatic cylinders, the extension and retraction of which are controlled by the analysis computer 22.
The evaluation computer 22 is an evaluation unit of the entire device, which can receive the data signals from the optotachometer 2 and the three laser range finders 6, 7, 8 via data lines and evaluate the received signals. On the other hand, the extension and retraction of the four support uprights 3, 4, 9, 14 and the two pusher shoes 12, 17, as well as the output of the operating motor 21 of the belt conveyor, can be controlled by means of data transmission lines, thereby achieving an adjustment of the actual speed of the conveyor belt 19.
The variable speed adjustment and material detection processing device of the invention can be used independently or a plurality of devices of the invention can be combined and used on one conveyor at the same time under the influence of the conveying distance of the belt conveyor (only two devices of the invention are shown in figure 2).
With reference to the description of the above structural features and with reference to fig. 1 and 2, the following is a detailed explanation of the working principle of the device according to the invention when used alone:
the invention has simple structure, easy disassembly and no influence from the model structure of the belt conveyor, and only needs to fix the supporting bottom plates 1 and 5 of the device on the bottom frame 20 of the conveyor when in installation. When materials such as coal blocks are transported by the belt conveyor, the photoelectric speed measuring instrument 2 can detect the actual running speed of the belt passing through the upper part of the photoelectric speed measuring instrument in real time and transmit data to the analysis computer 22, the three laser distance measuring instruments 6, 7 and 8 can also transmit the detected distance signals between the three laser distance measuring instruments and the belt right above the three laser distance measuring instruments to the analysis computer 22, and the analysis computer 22 can analyze the received data signals. When the analysis computer 22 finds that the actual carrying speed of the belt is low (lower than the carrying requirement range) through the data signal transmitted by the photoelectric speed meter 2, the data transmitted back by the three laser distance meters 6, 7 and 8 are checked first, if the data transmitted back by the three laser distance meters 6, 7 and 8 are all in the normal range (namely, the phenomenon that the conveying is overloaded or the material deviates from one side of the belt is avoided), the analysis computer 22 gives an instruction to the running motor 21 to increase the power of the running motor, so that the actual carrying speed of the conveying belt 19 is increased, the increase of the output power of the running motor 21 is stopped until the actual running speed of the belt fed back by the photoelectric speed meter 2 is recovered to the normal range, and the power is kept.
On the contrary, if the analyzing computer 22 finds that the actual carrying speed of the belt is low through the data signals transmitted by the photoelectric speed measuring instrument 2, the data transmitted back by the three laser distance measuring instruments 6, 7 and 8 are all abnormal (i.e. the phenomenon of overload in transportation or material deviation to one side of the belt occurs). The analysis computer 22 will analyze the abnormal data first and then give instructions to the four supporting posts 3, 4, 9, 14 and the two pushing rods 12, 17, and through the instructions given to them, the materials are pushed through the pushing baffles 13, 18, so as to eliminate the abnormal situation, and then give instructions to the running motor 21 to increase its power, so as to increase the actual carrying speed of the belt, and the increase of the output power of the running motor 21 is not stopped until the actual running speed of the belt fed back by the photoelectric velocimeter 2 is recovered to the normal range, and the power is maintained.
Similarly, when the analysis computer 22 finds that the actual carrying speed of the belt is high (higher than the carrying requirement range) through the data signal transmitted by the photoelectric velocimeter 2, it will be up to the instruction to perform the same operation process as the above-mentioned actual carrying speed is low.
While the foregoing is directed to the preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
