[0009] Preferably, the size of the card slot matches that of the spiral bar, and there are two groups of card slots and spiral bars, the internal slide groove of the pushing seat is inclined toward one end of the crushing blade, the number of the clamping components is three groups, and the three groups of clamping components are arranged in a triangular array inside the pushing seat.

[0010] Preferably, the power roller is connected to the adjusting roller by a belt transmission, the power roller is a cylindrical structure, the cross-section of the movable block is a trapezoidal structure, the adjusting block is a "T"-shaped structure, the number of the adjusting blocks is six groups, and the six groups of adjusting blocks are all slidingly connected to the movable block, the movable block is threadedly connected to the screw, and the length of the limit strip is shorter than the toggle strip.

[0011] Preferably, the ball head and the slider are inlaid and connected, the outer side of the ball head is provided with frosted lines, the direction of the crushing blade is opposite to the spiral strip, and the crushing blade is detachably connected to the pushing seat.

[0012] Preferably, a rotating motor is installed on the outer side of the fixing seat at one end of the power roller, a turntable is provided at the end of the screw, and the toggle bars and the limit bars are each in four groups, with two bars in each group.

[0013] Preferably, a feed port is provided at the bottom end of the outer side of the conveying pipe, a discharge port is provided at the top end of the outer side of the conveying pipe, and an annular pattern is provided on the outer wall of the connecting rope.

[0014] The feeding mechanism for a grinding mill proposed by the present invention has the following beneficial effects:

[0015] 1. Through the provided card slots and spiral bars, when the rotating motor drives the power roller to rotate, the toggle bar on the outside will make the push seat in the conveying pipe move forward, and according to the matching of the card slots on the outside of the push seat and the spiral bars, the push seat can rotate during the forward process, so that the crushing blade at one end of the push seat can perform preliminary crushing on the material in the process of pushing the material, and the material will also be affected by the spiral bars and move toward one end of the crushing blade during the pushing process, forming an internal circulation, so that the preliminary crushing of the material is more comprehensive, and the crushing effect of the material is further improved.

[0016] 2. According to the structure that the slide grooves in the three groups of clamping components inside the push seat are inclined on one side, the effect is that when the push seat moves toward the side of the crushing blade, the ball heads in the three groups of slide grooves slide inwards under the influence of the connecting rope and squeeze the connecting rope together, so as to fix the push seat on the outside of the connecting rope. When the push seat moves in the opposite direction, the ball heads in the three groups of clamping components will slide outwards together with the sliders under the influence of the connecting rope. At this time, the clamping force on the connecting rope will be lost, and the push seat can be displaced. The connecting rope and the push seat on its outside are in the conveying The tube is a closed-loop structure. During use, the rotating motor drives the power roller to rotate, and the toggle bar on the outside thereof contacts the push seat. Combined with the structure that the push seat moves forward to clamp the connecting rope, the toggle bar can toggle the entire push seat and the connecting rope to operate, thereby realizing the material transportation operation. During the feeding process, the movable block is respectively connected with the screw thread and the six groups of adjustment blocks for sliding connection, so that the rotation of the screw can drive the movable block to move left and right under the restriction of the six groups of adjustment blocks, and the movable block is a group of vertical cross-sections of ladder-shaped. The cylindrical body has different diameters at different positions, so that the left and right movement of the movable block can change the extended length of the adjusting block sleeved in the adjusting roller, and the rubber skin sleeved on the outside of the six groups of adjusting blocks makes the power roller and the adjusting roller rotate synchronously. The specific effect of this structure is that when the distance between the six groups of adjusting blocks and the center of the adjusting roller is the same as the diameter of the power roller, the rotation of the adjusting roller will also be synchronized with the power roller, and the limiting strip on the outside will not produce a force on the pushing seat on the outside of the connecting rope, but as the movement of the movable block causes the change of the extended length of the six groups of adjusting blocks, the distance between the center of the adjusting roller will also change. When this distance is greater than the diameter of the power roller, the rotation rate of the adjusting roller will be slower than that of the power roller, and the limiting strip on the outside will move the side of the pushing seat holding the crushing blade to change its position. When the positions of all the pushing seats are changed, the distance between the pushing seats will also change, and the materials that can be transported will also change accordingly. Compared with the existing conveying equipment, this structure can be adjusted immediately as needed during the material transportation process without stopping the machine to affect the entire operation process, and it is easy to operate.

A slider 2092 is provided inside 91, a ball head 2093 is provided at the end of the slider 2092, a spring 2094 is provided between the tail of the slider 2092 and the slide groove 2091, the size of the slot 206 matches the spiral strip 203, and the number of the slot 206 and the number of the spiral strip 203 are both two groups, the slide groove 2091 inside the push seat 204 is inclined toward one end of the crushing blade 208, the number of the clamping components 209 is three groups, and the three groups of clamping components 209 are arranged in a triangular array inside the push seat 204.

[0030] By setting the clamping assembly 209, when the push roller moves on the outside of the connecting rope 205 toward one end of the crushing blade 208, the slider 2092 in the three groups of clamping assemblies 209 will use the ball head 2093 to squeeze the connecting rope 205 inward, thereby limiting the pushing seat. When the pushing seat moves in the opposite direction, the slider 2092 in the three groups of clamping assemblies 209 will slide outward, and the clamping of the connecting rope 205 will be lost, so that the pushing seat can be displaced.

[0031] The adjusting mechanism 4 includes a power roller 401, a toggle bar 402 is arranged on the outer side of the power roller 401, a tooth pattern 403 is arranged on the outer wall of the power roller 401, an adjusting roller 404 is arranged on one side of the power roller 401, a limit bar 410 is arranged on the outer side of the adjusting roller 404, an adjusting block 405 is arranged on the inner wall of the adjusting roller 404, a movable block 406 is arranged inside the adjusting roller 404, a screw 407 is arranged inside the movable block 406, a belt 408 is sleeved on the outer side of the power roller 401 and the adjusting roller 404, and the power roller is driven by the belt 408 and the adjusting roller The power roller 401 is in a cylindrical structure, the cross section of the movable block 406 is in a trapezoidal structure, the adjusting block 405 is in a "T"-shaped structure, the number of the adjusting blocks 405 is six groups, and the six groups of adjusting blocks 405 are all slidingly connected to the movable block 406, the movable block 406 is threadedly connected to the screw 407, the length of the limit bar 410 is shorter than the toggle bar 402, the elastic block 411 is made of natural rubber, the power roller 401 and the adjusting roller 404 rotate clockwise, the pushing seat 204 rotates clockwise, and the end of the pushing seat 204 with the crushing blade 208 is in the forward direction.

[0032] By setting the movable block 406, the vertical cross-section of the movable block 406 is a trapezoidal structure. When its position changes inside the adjusting roller 404, the extended length of the adjusting block 405 inside the adjusting roller 404 will change, which will also cause the movement trajectory of the belt 408 connected to the outside of the adjusting roller 404 to change. The effect achieved is that when the movement trajectory of the belt 408 on the outside of the adjusting roller 404 is greater than the power roller 401, the rotation speed of the adjusting roller 404 is reduced, otherwise the rotation speed is increased. By setting the elastic block 411, soft rubber is used to distinguish it from the hard rubber material of the belt 408, in order to prevent the 408 belt from cracking due to the expansion of the adjusting block 405.

[0033] Among them, the ball head 2093 and the slider 2092 are inlaid and connected, and the outer side of the ball head 2093 is provided with frosted texture. The direction of the crushing blade 208 is opposite to that of the spiral bar 203, and the crushing blade 208 is detachably connected to the pushing seat 204. A rotating motor 409 is installed at one end of the power roller on the outer side of the fixed seat 3, and a turntable is provided at the end of the screw 407. The toggle bar 402 and the limit bar 410 have the same structure, and the ends of the toggle bar 402 and the limit bar 410 are connected with a telescopic rod 412. The number of the toggle bar 402 and the limit bar 410 is six groups, the bottom end of the outer side of the conveying pipe 201 is provided with a feed port 5, the top end of the outer side of the conveying pipe 201 is provided with a discharge port 6, and the outer wall of the connecting rope 205 is provided with annular texture.

[0034] By setting up the retractable rod 412, according to the retractable relationship between the retractable rod 412 and the limit strip 410, the retractable rod 412 can still be moved to adjust the pushing seat 404 after it is displaced. Specifically, the retractable rod 412 in contact with the pushing seat 404 will shrink and will not affect the pushing seat 404, while the unshrinkable area can be adjusted even after the pushing seat 404 is displaced.

[0035] Working principle: When in use, pour the material into the feed port 5. According to the inclined structure of the slide groove 2091 in the three groups of clamping components 209 inside the push seat 204, the effect is that when the push seat 204 moves toward one end of the crushing blade 208, the ball head 2093 in the three groups of slide grooves 2091 slides inwardly under the influence of the connecting rope 205, and jointly squeezes the connecting rope 205, thereby fixing the push seat 204 on the outside of the connecting rope 205. When the push seat 204 retreats in the opposite direction, the ball head 2093 in the three groups of clamping components 209 will slide outward together with the slider 2092 under the influence of the connecting rope 205, and the connecting rope 205 will be lost. 05, the pushing seat 204 can be displaced, the connecting rope 205 and the pushing seat 204 on its outer side are used as a closed loop structure in the conveying pipe 201. During use, the rotating motor 409 drives the power roller 401 to rotate clockwise, and the telescopic rod 412 at the end of the outer toggle bar 402 will contact the pushing seat 204. Combined with the structure that the clockwise movement of the pushing seat 204 clamps the connecting rope 205, the toggle bar 402 will toggle the entire pushing seat 204 and the connecting rope 205 to operate, thereby realizing the material transportation operation. During the feeding process, according to the movable block 406 being threadedly connected with the screw rod 407 and the six sets of adjustment blocks 405 sliding The movable connection makes the rotation of the screw rod 407 drive the movable block 406 to perform telescopic movement under the restriction of the six groups of adjusting blocks 405. Since the movable block 406 is a group of cylinders with trapezoidal vertical cross-sections and different outer diameters, the six groups of adjusting blocks 405 are expanded due to the movement of the movable block 406. The specific effect of this structure is that when the six groups of adjusting blocks 405 are not expanded, the rotation speed of the adjusting roller 404 is synchronized with the power roller 401, and the outer limit strip 410 of the adjusting roller 404 and the connecting rope 205 and the pushing seat 204 are in a relatively static state, so no force is generated on the pushing seat 204, but as the movable block 406 moves, the six groups of adjusting blocks 405 are expanded, resulting in When the rotation speed of the adjusting roller 404 is slower than that of the power roller 401, the relative static state of the limiting strip 410, the connecting rope 205 and the pushing seat 204 on the outside of the adjusting roller 404 is broken, and the normally extended 412 at the end thereof will move the side of the pushing seat 204 holding the crushing blade 208, so that its position changes. When the positions of all the pushing seats 204 are changed, the distance between the pushing seats 204 and the pushing seats 204 will also be changed, and the amount of materials that can be transported will also change accordingly. Compared with the existing conveying equipment, this structure can immediately adjust the quantitative amount of the conveyed materials during the material transportation process without stopping the machine to affect the entire operation process, and the operation is simple;During the conveying process, through the provided slots 206 and spiral strips 203, when the rotating motor 409 drives the power roller 401 to rotate, the outer toggle strips 402 will make the push seat in the conveying pipe move forward clockwise, and according to the matching of the slots 206 on the outer side of the push seat 402 and the spiral strips 203, the push seat 204 can rotate during the forward process, so that the crushing blade 208 at one end of the push seat can initially crush the material during the pushing process, and the material will also be affected by the spiral strips 203 and move toward one end of the crushing blade 208 during the pushing process, forming an internal cycle, so that the initial crushing of the material is more comprehensive, and the crushing effect of the material is further improved. ;

[0036] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
