[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.
[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0029] Example 1, reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a sampling machine limited drop hopper anti-blocking coal device, including a track 101 constructed by multiple steel pipes for supporting a trolley body 102, which is the track 101 for the movement of the trolley body 102, the trolley body 102 is used to carry a trolley and move laterally along the track 101, and the lower side of the trolley body 103 and the upper side of the trolley body 103 are both provided with an induction flat iron 104a, and the induction flat iron 104a cooperates with a trolley proximity switch 105 and a trolley proximity switch 105e;
[0030] The large vehicle proximity switch 105 and the small vehicle proximity switch 105e include a wiring terminal 105a, a common line 105b, a power line 105c and a signal line 105d. Figure 4 The signal line 105d is the signal output line of the proximity switch, which transmits the state of the proximity switch to the control system. The power line 105c is the power line 105c of the proximity switch, which receives +24V power from the control system. The common line 105b is the common line 105b of the proximity switch, which is connected to the negative pole of the power line 105c. The terminal 105a is used to connect the lead wire of the proximity switch.
[0031] During use, the trolley body 103 is sampling in the parking area. At this stage, the trolley body 103 does not touch the trolley travel switch 104b, so the trolley travel switch 104b does not work, and the large vehicle body 102 moves left and right along the length direction of the carriage. At this stage, the large vehicle proximity switch 105 limit does not work;
[0032] After the sampling is completed, the sampling machine driver operates the trolley body 103 to move to one side. After the trolley body 103 moves to a certain position, it touches the trolley travel switch 104b, triggering the action of the trolley travel switch 104b. The action of the trolley travel switch 104b turns on the limit switch 105 of the large vehicle, which is energized, so that the limit switch 105 of the large vehicle starts to work;
[0033] The trolley body 102 starts to move above the hopper. During the movement of the trolley body 102, the limit sensing flat iron 104a approaches the trolley proximity switch 105 to limit the position. When the limit sensing flat iron 104a triggers the trolley proximity switch 105 to limit the position, the trolley body 102 stops running.
[0034] The trolley body 103 is operated to continue to move toward the primary feeder 201 side, and the trolley body 103 moves to the limit trigger point of the trolley proximity switch 105e and stops. At this time, the unloading point of the sampling cylinder 202a bypassing the coal drop pipe 202d is accurately positioned above the coulter of the angle steel 203c in the receiving hopper 203b.
[0035] Example 2, reference Figure 3 and Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a sampling barrel 202a is fixedly installed on the trolley body 103, and the sampling barrel 202a has a cylindrical structure. A driving motor 202b is arranged on the upper end of the sampling barrel 202a, and a spiral plate 202c is arranged in the sampling barrel 202a. The output shaft of the driving motor 202b is connected to the central axis of the spiral plate 202c. The spiral plate 202c is spiral-shaped, similar to the shape of a spiral staircase. There is a small gap between the outer wall of the blades of the spiral plate 202c and the inner wall of the sampling barrel 202a, which ensures that the spiral plate 202c can ensure that the coal blocks it transports will not escape from the conveying path of the spiral plate 202c from the gap when the spiral plate 202c rotates normally.
[0036] Furthermore, a coal drop pipe 202d is provided on the outer wall of the sampling cylinder 202a. The coal drop pipe 202d is connected to the sampling cylinder 202a. The coal drop pipe 202d is an inclined pipe. The angle between the coal drop pipe 202d and the sampling cylinder 202a is 45 degrees. Once the coal enters the coal drop pipe 202d, since the coal drop pipe 202d is inclined, the coal will flow along the coal drop pipe 202d under the action of gravity, and finally flow out from the other end of the coal drop pipe 202d. An electric baffle 202e is provided at the other end of 2d, and the electric baffle 202e is controlled by a motor to realize the rotation of the electric baffle 202e. The inner side of the electric baffle 202e adjacent to the mouth of the coal dropping pipe 202d is in the shape of a semicircular groove, which is convenient for the electric baffle 202e to intercept the flow of the coal dropping pipe 202d. When the electric baffle 202e is closed, it will block the other end of the coal dropping pipe 202d, preventing the coal from flowing out of the pipe mouth, and temporarily storing the coal blocks in the coal dropping pipe 202d in the pipe.
[0037] Furthermore, it also includes a feeder 201, a fixed frame 203a is provided on the feeder 201, a receiving hopper 203b is provided on the fixed frame 203a, an angle steel 203c is provided in the receiving hopper 203b, the angle steel 203c is designed in the shape of a plow blade, and its edges and corners face upwards, and is used to break the wet frozen coal blocks that fall. The angle steel 203c is installed inside the receiving hopper 203b, and the specific position is to allow the falling coal blocks to have an impact force during the falling process under the action of gravity, and be plowed and decomposed after hitting the angle steel 203c;
[0038] By adding angle steel 203c, the whole piece of wet coal can be prevented from falling directly onto the feeder 201 belt, thereby preventing the feeder 201 belt from being compressed and the motor from tripping due to exceeding the output. In order to make the mouth of the coal drop pipe 202d just above the newly installed angle steel 203c in the hopper to achieve the best crushing effect, it is necessary to locate the traveling position of the sampler trolley and the trolley, install the trolley proximity switch 105e limit switch, the trolley proximity switch 105 limit switch, and the trolley travel switch 104b, and make corresponding modifications to the sampler program to achieve this.
[0039] During use, the driving motor 202b at the upper end of the sampling cylinder 202a is started, and the output shaft of the driving motor 202b is connected to the central axis of the spiral plate 202c, so that the spiral plate 202c rotates, and the lower end of the sampling cylinder 202a contacts the coal carried on the car. The coal rises along the spiral path under the conveyance of the spiral plate 202c. After the coal reaches the upper end of the sampling cylinder 202a, it falls into the coal drop pipe 202d connected to the sampling cylinder 202a.
[0040] The coal blocks flow along the coal drop pipe 202d under the action of gravity, and finally flow out from the other end of the coal drop pipe 202d. Since the electric baffle 202e at the other end of the coal drop pipe 202d is in a closed state at this time, the coal blocks are temporarily stored in the coal drop pipe 202d. When the electric baffle 202e is opened, the electric baffle 202e allows the coal blocks to flow out of the coal drop pipe 202d.
[0041] The other end of the coal drop pipe 202d is located just above the angle steel 203c plowshare in the receiving hopper 203b, so that the frozen coal blocks fall exactly on the angle steel 203c plowshare, and the crushing effect is good.
[0042] The remaining structures are the same as those of Example 1.
[0043] Example 3, reference Figure 2 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: it includes the cooperation between the trolley proximity switch 105 and the trolley proximity switch 105e and the induction flat iron 104a respectively, the power line 105c is connected to the +24V power output end of the control system, the positive pole of the power line 105c is connected to the positive output of the control system, and the negative pole is connected to the common line 105b, the signal line 105d is responsible for transmitting the state of the proximity switch to the control system, the signal line 105d is connected to the input end of the control system, and the wiring terminal 105a is used to connect the lead wire of the proximity switch;
[0044] Before powering on, perform a visual check to ensure all wiring is correct, power on the control system, check that the proximity switches are working as expected, test the proximity switches under actual working conditions, communicate correctly with the control system, and control the movement of the trolley and cart as expected, monitor the working status of the proximity switches during operation, and be able to detect the induction flat iron 104a.
[0045] The remaining structure is the same as that of the embodiment.
