[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] See also Figures 1-9 As shown, the present invention provides a technical solution: an impact hammer crusher, comprising an impact hammer crushing mechanism 1, an anti-jamming mechanism 2 is provided at the bottom of the impact hammer crushing mechanism 1;

[0036] The anti-jamming mechanism 2 includes two servo motors 201, a first controller 211, a second controller 212 and a third controller 213. The output ends of the two servo motors 201 are fixed with screw rods 202. The outer surfaces of the two screw rods 202 are fixedly sleeved with limit rings 203. One end of the two screw rods 202 is threadedly sleeved with two T-blocks 204. A rectangular block 205 is fixed between the bottoms of the four T-blocks 204. A comb plate 206 is movably sleeved between the outer surfaces of the four T-blocks 204. Two symmetrical cylindrical blocks 207 are fixed to the bottom of the comb plate 206. Two symmetrical U-shaped frames 208 are installed at the bottom of the rectangular block 205. Two symmetrical cylindrical holes 209 are opened on the top of the rectangular block 205. Electric push rods 21 are provided inside the two cylindrical holes 209. 0; The cleaning mechanism 3 includes a pair of flip telescopic rods 301 hingedly arranged at the bottom of the impact hammer crushing mechanism 1, and a guide rod 305 is connected between the ends of the two flip telescopic rods 301 away from the hinge axis, and a screw rod 304 is installed in parallel on the outer side of the guide rod 305. A displacement motor 303 for driving the screw rod 304 to rotate is installed at one end of the guide rod 305, and a cleaning plate 302 is equidistantly provided between the ends of the two flip telescopic rods 301 away from the hinge axis. The front end of the cleaning plate 302 is inclined to facilitate unloading. The cleaning plate 302 is respectively provided with an internal threaded hole and a sliding hole adapted for the screw rod 304 and the guide rod 305. When the displacement motor 303 rotates forward and backward, the screw rod 304 is driven to drive the cleaning plate 302 to translate axially along the guide rod 350.

[0037] Further, see Figure 8The flipping of the flip telescopic rod 301 can be achieved by adding a hinged telescopic member as shown in the figure. The telescopic member can be a cylinder or a hydraulic cylinder, an electric telescopic rod, wherein the bottom of the impact hammer crushing mechanism 1 can also be provided with a driving motor (not shown in the figure) for driving a pair of flip telescopic rods 301 to swing. The cleaning plate 302 has the same structure as the comb plate 206, but the vertical positions are staggered with each other, so that the cleaning mechanism 3 can be turned over, swung and extended to clamp the cleaning plate 302 between the comb plates 206 or insert it into the bottom of the impact hammer crushing mechanism 1 (between two adjacent discharge grate bars 112) under the action of the flip telescopic rod 301, thereby cleaning the comb plates 206. The cleaning process is to clean the bottom discharge port of the impact hammer crushing mechanism 1 to prevent the crushed material from clogging the bottom discharge port of the impact hammer crushing mechanism 1 or getting stuck in the gap of the comb plate 206; in order to prevent the comb teeth of the comb plate 206 and the cleaning plate 302 from colliding with each other, a "V"-shaped guide surface can be set at one end of the cleaning plate 302 facing the comb plate 206, so that when the cleaning plate 302 swings toward one end of the comb plate 206, it can be slid and guided to the gap of the comb plate 206 through the guide surface, thereby achieving the purpose of cleaning the gap of the comb plate 206. Furthermore, the position of the cleaning plate 302 disclosed in the present application is adjustable, so the accuracy of interlacing can be greatly improved.

[0038] Furthermore, since the cleaning mechanism 3 cannot work continuously to avoid affecting crushing and falling materials, in this embodiment, the cleaning mechanism 3 also includes a detection component for monitoring falling materials, that is, for detecting falling material conditions to determine whether a blockage occurs. The detection component includes a plurality of infrared emitting ends 306 arranged parallel to the guide rod 305, and the infrared emitting ends 306 are arranged at equal intervals between the two ends of the flip telescopic rods 301 away from the hinge axis. The bottom of the impact hammer crushing mechanism 1 is provided with a plurality of infrared receiving ends (not shown in the figure), and the infrared receiving ends are aligned with the infrared emitting ends 306. It can be understood that the infrared receiving end is provided at the bottom of the impact hammer crushing mechanism 1 on the side of the discharge grate 112 away from the infrared emitting end 306, so that a "detection network" for detecting material falling conditions is formed between the infrared emitting end 306 and the infrared receiving end. When the material is crushed and fallen normally, the workstation receiving end will generate intermittent irregular electrical signals, and when the material is blocked, the infrared signal of the blocked part will be continuously received by the receiving end to generate a continuous electrical signal, thereby determining whether the material is blocked. Whether the material falls smoothly, wherein the infrared receiving end can be arranged in multiple columns in a rectangular array. The purpose is to use the flip telescopic rod 301 to swing back and forth within a small angle range in the reset state to improve the detection accuracy, that is, the signal of one group of infrared transmitting ends can be received by multiple groups of receiving ends to avoid errors. When the infrared receiving end receives the electrical signal generated by the infrared transmitting end 306 for a long time, it indicates that the material that does not block the infrared light will fall here and in this interval, then the two adjacent discharge grate bars 112 are bound to be blocked. The processor controls the displacement motor 303 to adjust the cleaning plate 302 to move to the preset position and clean it for unblocking and use. The cleaning length set by the cleaning plate 302 can be arbitrary, which can be the entire blanking port or half of the blanking port. Taking the length interval of the discharge grate 112 set to 1M as an example, the length of the cleaning plate 302 set at equal intervals can be 1M or 0.5 meters, preferably 0.5M. The purpose is to clean the discharge grate 112 when it is blocked without affecting the continued blanking of the unblocked part, which will not be elaborated here.

[0039] As those skilled in the art can understand, the technical solution based on infrared detection and determination of position coordinates can be implemented and understood, in which each infrared emitting end acts as a position coordinate corresponding to the coordinates where blockage may occur, and secondly, how the displacement motor controls the actual position of the cleaning plate 302 can be determined by using a displacement sensor or based on the value of the motor rotation angle sensor, so they will not be elaborated one by one.

[0040] Among them, the thickness and gap of each comb tooth rack of the comb plate 206 are adjusted according to the actual through hole size and the spacing between the through holes of the discharge grate 112, and the thickness and gap of each comb tooth rack of the cleaning plate 302 are adjusted according to the thickness and gap of each comb tooth rack of the comb plate 206 and the discharge grate 112. Therefore, there is no limitation on the size of the comb plate 206 and the cleaning plate 302.

[0042] according to Figure 1 、 Figure 2 、 Figure 5 and Figure 7 As shown, the impact hammer crushing mechanism 1 includes a crushing box 101, a first controller 211, a second controller 212 and a third controller 213 are all installed on the front surface of the crushing box 101, a mounting frame 102 is installed inside the crushing box 101, a first impact plate 103 is installed on the arc surface of the mounting frame 102, a feed pipe 105 is fixed on the top of the crushing box 101, a guide plate 106 is fixed on one side of the inner wall of the crushing box 101, and a second impact plate 104 is fixed on the bottom of the guide plate 106, so that large stones can be crushed with the cooperation of the first impact plate 103, the second impact plate 104 and the hammer head 115.

[0043] according to Figure 2 、 Figure 5 and Figure 7 As shown, a support plate 107 is fixed to the bottom of the inner wall of the crushing box 101, and the inclined surface of the support plate 107 is fixed to the bottom inclined surface of the guide plate 106. A concave block 108 is fixed to the bottom of the inner wall of the crushing box 101. A cover plate 109 is connected to the inlet of the feed pipe 105 by a hinge. Connecting blocks 110 are fixed on both sides of the feed pipe 105 and both sides of the cover plate 109. The two upper connecting blocks 110 are threaded with hand bolts 111, and one end of the two hand bolts 111 is threaded through the top of the two lower connecting blocks 110, so that under the action of the support plate 107, support force can be provided for the guide plate 106.

[0044] according to Figure 2 、 Figure 5 and Figure 6As shown, the interior of the crushing box 101 is provided with a discharge grate 112, and the two ends of the discharge grate 112 are respectively in contact with one end of the first impact plate 103 and one end of the second impact plate 104. The interior of the crushing box 101 is rotatably connected to a rotating rod 113 through a first bearing, and the two ends of the rotating rod 113 are respectively movable through the front surface and the rear surface of the inner wall of the crushing box 101. The outer surface of the rotating rod 113 is fixedly sleeved with a rotor 114, which is convenient for discharging gravel that meets the particle size under the action of the discharge grate 112.

[0045] according to Figure 2 、 Figure 5 and Figure 6 As shown, multiple hammer heads 115 are evenly distributed inside each groove of the rotor 114, and a protective shell 116 is installed on each hammer head 115. Two symmetrical limit blocks 117 are fixed to the outer wall of the discharge grate 112. A rectangular plate 118 is fixed to the bottom of the mounting frame 102, and the bottom of the rectangular plate 118 is in contact with the bottom of the inner wall of the crushing box 101. One of the limit blocks 117 is installed on the other side of the concave block 108 by a first bolt, and the other limit block 117 is installed on one side of the rectangular plate 118 by a second bolt, so that the stability of the discharge grate 112 during operation can be improved with the cooperation of the limit block 117 and the first bolt.

[0046] according to Figure 2-Figure 4 and Figure 6 As shown, two placement racks 122 are provided at the bottom of the crushing box 101, the bottom of the crushing box 101 and the top of one of the placement racks 122 are fixed, the opposite sides of the two placement racks 122 are fixed, the other ends of the two screw rods 202 are rotatably connected to the other side of the inner wall of one of the placement racks 122 through a second bearing, support blocks 123 are fixed to the four corners of the bottom of the two placement racks 122, and a drive motor 119 is installed on the top of the other placement rack 122. A flywheel 120 is installed on the output end of the drive motor 119 and the outer surface of the rotating rod 113, and the two flywheels 120 are connected by a belt drive. A fixed disk 121 is installed on the front surface of the rotating rod 113, and a motor controller 124 is installed on the front surface of the crushing box 101. The motor controller 124 is electrically connected to the drive motor 119, so that the drive motor 119 can be controlled to start or shut down under the action of the motor controller 124.

[0047] according to Figure 2 、 Figure 5 and Figure 6As shown, guard plates 125 are fixed to the front surface and rear surface of the inner wall of the crushing box 101, and the opposite sides of the two guard plates 125 are in contact with the front surface and rear surface of the guide plate 106, the front surface and rear surface of the concave block 108, the front surface and rear surface of the rotor 114, the front surface and rear surface of the first impact plate 103, the front surface and rear surface of the second impact plate 104, the front surface and rear surface of the support plate 107, the front surface and rear surface of the discharge grate 112 and the front surface and rear surface of the mounting frame 102, so that the inner wall of the crushing box 101 can be protected under the action of the guard plates 125.

[0048] The effect achieved by the entire mechanism is: when it is necessary to crush large stones, the drive motor 119 is directly started by the motor controller 124. The started drive motor 119 will drive the flywheel 120 connected thereto to rotate, and the rotating flywheel 120 will drive the rotating rod 113 to rotate under the cooperation of the belt, bearing and another flywheel 120, and the rotating rotating rod 113 will drive the fixed disk 121 to rotate, and the rotating rotating rod 113 will also drive the rotor 114 to rotate, and the rotating rotor 114 will also drive all the hammer heads 115 to rotate, and each rotating hammer head 115 will drive the protective shell 116 connected thereto to rotate. At this time, the two hand-tightening bolts 111 are directly removed, and then the cover plate 109 is directly rotated. The rotating cover plate 109 will also drive the connecting block 110 connected thereto to rotate, and then the large stones to be crushed are put in from the inlet of the feed pipe 105, and then the large stones are crushed directly through the cooperation of the guide plate 106, the first impact plate 103, the second impact plate 104 and the discharge grate 112, and the rotating hammer head 115 and the protective shell 116. Finally, the crushed stones will pass directly through the through holes of the discharge grate 112, thus achieving the crushing of the large stones; when the through holes of the discharge grate 112 are blocked by crushed stones, the cleaning mechanism 3 or the anti-jamming mechanism 2 can be used to clean the through holes of the discharge grate 112, wherein the anti-jamming mechanism 2 can both clean the discharge grate 112 and is mainly used for cleaning the cleaning mechanism 3. Of course, if the anti-jamming mechanism 2 is used to clean the through hole of the discharge grate 112, it is necessary to stop putting the big stone into the feed pipe 105, and at the same time use the motor controller 124 to turn off the drive motor 119, then set the third controller 213 to use the program, and use the first controller 211 to start the two servo motors 201 at the same time. At this time, the two servo motors 201 started are all driven by the second bearing to drive the screw 202 connected thereto to rotate. At this time, the two rotating screws 202 will drive all the T-blocks 204 to move horizontally with the cooperation of one of the placement racks 122 and the rectangular block 205, and the moving four T-blocks 204 will also drive the rectangular block 205 to move horizontally together. When the rectangular block 2 05 moves, the moving rectangular block 205 will drive the U-shaped frame 208, the electric push rod 210, the cylindrical block 207 and the comb plate 206 to move horizontally. When the two T-blocks 204 are in contact with the two limit rings 203 respectively, the first controller 211 will control the two servo motors 201 to turn off. At this time, the third controller 213 will use the second controller 212 to control the two electric push rods 210 to start at the same time. At this time, the two started electric push rods 210 will push the two cylindrical blocks 207 to move vertically upward with the cooperation of the two U-shaped frames 208, the four T-blocks 204, one of the placement racks 122 and the rectangular block 205. At the same time, the two cylindrical blocks 207 that move upward will drive the comb plate 206 to move vertically upward together.At this time, the comb plate 206 that moves vertically upward will directly squeeze out the gravel that is blocked on the through hole of the discharge grate 112, that is, prevent the normal passage of the gravel of the discharge grate 112. When the comb plate 206 completes the stone discharge, the second controller 212 will control the telescopic ends of the two electric push rods 210 to move back. At this time, the comb plate 206 will move back to the initial position under the action of its own gravity. When the two electric push rods 210 complete the reset operation, the comb plate 206 also completes the reset movement. At this time, the second controller 212 will directly turn off the two electric push rods 210. At the same time, the third controller 213 will also use the first controller 211 to synchronously control the two servo motors 201 to start and reverse. At this time, the two servo motors 201 will rotate on the screw 202 and the T-block 20 4 and the rectangular block 205 cooperate to directly drive the comb plate 206 to return to its initial position. When the comb plate 206 returns to its initial position, the first controller 211 will directly turn off the two servo motors 201, completing the unblocking operation of the discharge grate 112. Under normal circumstances, the cleaning mechanism 3 is used to clean the through holes of the discharge grate 112. The cleaning mechanism 3 cleans the through holes of the discharge grate 112 by determining the blockage position based on the above-mentioned detection component and adjusting the position of the cleaning plate 302 in conjunction with the counterclockwise swing of the flip telescopic rod 301.
