[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] As shown in FIGS. 1-8, this embodiment provides a tool head assembly of a splitter, which includes a swing frame device 11 and an adaptive splitting tool device 12. The swing frame device 11 is fixedly installed at the output end of the main drive component 4. The adaptive splitting tool device 12 includes an adaptive action component 121, a tool holder push valve 122, and a sliding blade component 123 that are connected in sequence from top to bottom. The adaptive splitting tool device 12 is fixedly installed at the bottom end of the swing frame device 11 and swings left and right following the swing frame device 11.

[0027] In this embodiment, the swing frame device 11 includes a locking seat 111, an arc groove block 112, an arc block 113, a side plate 114, a swing pin 115, a tool holder bottom plate 116, a swing buffer 117, and a swing limit component 118. The locking seat 111 is fixedly installed at the output end of the main drive component 4. The arc block 113 is fixedly installed at the top of the tool holder bottom plate 116. The arc groove block 112 is fixedly installed at the bottom of the locking seat 111. The arc groove block 112 is provided with an arc surface that fits and slides with the arc block 113. The side plate 114 is fixedly installed on the arc groove block 112 and its bottom is hinged to the tool holder bottom plate 116 through the swing pin 115. The axis of the swing pin 115 coincides with the axis of the arc surface. When the left and right sides of the brick are of unequal height or the surface of the brick is uneven, the tool holder bottom plate 116 squeezes the arc block 113 to slide on the arc surface of the arc groove block 112. Since the axis of the swing pin 115 coincides with the axis of the arc surface, the tool holder bottom plate 116 rotates around the swing pin 115 to adapt to the surface of the brick, avoiding uneven force on the brick and being split. One end of the swing buffer 117 is connected to the locking seat 111 and the other end is connected to the tool holder bottom plate 116.

[0028] In this embodiment, the swing frame device 11 includes an adaptive movement groove 1111, which is arranged on the lower side of the tool rest base plate 116. The tool rest base plate 116 is provided with a wedge block adjusting screw 1212. The wedge block adjusting screw 1212 is threadedly connected to the tool rest base plate 116 and extends into the adaptive movement groove 1111 to squeeze the wedge block from the side. Rotating and adjusting the wedge block adjusting screw 1212 can make the wedge blocks approach or move away from each other. Any wedge block extends or retracts under the extrusion of the two side wedge blocks, thereby pushing the corresponding plunger 1222 and the corresponding main blade 1232 to move up and down, and further adjusting the up and down stroke of the main blade 1232.

[0029] In this embodiment, the swing limit assembly 118 includes a pair of swing limit members installed at both ends of the locking seat 111. The left and right ends of the locking seat 111 are provided with swing limit mounting cylinders 1114. The swing limit member includes a swing limit rod 1181 and a swing adjustment fastener 1182. The swing limit rod 1181 passes through the swing limit mounting cylinder 1114 and is fixedly installed on the swing limit mounting cylinder 1114 through the swing adjustment fastener 1182. The swing adjustment fastener 1182 is threadedly connected to the swing limit rod 1181. The swing limit rod 1181 is installed on the locking seat 111 and abuts against the tool rest base plate 116. The swing amplitude of the tool rest base plate 116 is limited by the swing limit rod 1181. Under the buffering of the swing buffer member 117, the tool rest base plate 116 can automatically return to the correct position after completing one brick splitting.

[0030] In this embodiment, swing buffer guide posts 1113 are provided at the lower ends on both sides of the locking seat 111. The swing buffer member 117 is sleeved on the swing buffer guide posts 1113 and both ends of the swing buffer member 117 respectively abut against the locking seat 111 and the tool rest base plate 116. The swing buffer member 117 will not come out under the limitation of the swing buffer guide posts 1113.

[0031] In this embodiment, the tool rest push valve 122 includes a valve body 1221 and a plurality of plungers 1222 that are slidably matched with the valve body 1221. The upper ends of the plungers 1222 abut against the adaptive movement assembly 121, and the lower ends abut against the corresponding main blades 1232.

[0032] In this embodiment, the sliding blade assembly 123 includes a plurality of pairs of tool rest clamping plates 1231 and a plurality of main blades 1232. Each pair of tool rest clamping plates 1231 is fixedly installed at the bottom of the tool rest push valve 122, and each pair of tool rest clamping plates 1231 clamps each main blade 1232 in the front-rear direction. Each main blade 1232 slides in the up-down direction under the clamping of the tool rest clamping plates 1231.

[0033] In this embodiment, the adaptive movement groove 1111 and the tool rest push valve 122 enclose an adaptive movement cavity. The adaptive movement assembly 121 includes a wedge block group 1211 horizontally distributed in the adaptive movement cavity. The wedge block group 1211 includes a number of wedge blocks. Each wedge block includes a narrow end, and the narrow ends of adjacent wedge blocks point in opposite directions. The wedge blocks are divided into lower-side wedge blocks 12111 that slide-friction with the top of the tool rest push valve 122 and upper-side wedge blocks 12112 that slide-friction with the bottom of the adaptive movement groove 1111. The upper end of the plunger 1222 abuts against the corresponding lower-side wedge block 12111. Each plunger 1222 conducts the extrusion force of the corresponding main blade 1232 to the corresponding lower-side wedge block 12111. When each lower-side wedge block 12111 is subjected to the extrusion force, it forces itself to contract inward and squeeze the adjacent upper-side wedge block 12112 to slide to both sides. In this way, when the main blade 1232 contacts uneven bricks, it can adaptively move up and down, avoiding uneven force on the bricks and greatly improving the quality of brick splitting.

[0034] In this embodiment, a wear-resistant plate 1112 is provided at the bottom of the adaptive movement groove 1111. The upper-side wedge block 12112 slides-friction with the wear-resistant plate 1112. The adaptive movement cavity is filled with grease, which increases the wear resistance and service life of the upper-side wedge block 12112 and the adaptive movement cavity.

[0035] In this embodiment, the upper tool head assembly further includes a side block group 13. The side block group 13 includes side blocks 131 respectively installed at the bottoms of both ends of the tool rest push valve 122 and clamping the left and right sides of the sliding blade assembly 123.

[0036] The working principle and usage process of the present invention:

[0037] Before brick splitting:

[0038] Adjust the wedge block adjusting screw 1212. The wedge block adjusting screw 1212 squeezes the wedge block from the side, and the distance between adjacent wedge blocks changes, thereby changing the expansion and contraction amount of the wedge block in the up and down directions.

[0039] Adjust the position of the swing adjustment fastener 1182 on the swing limit rod 1181, and then adjust the up and down position of the swing limit rod 1181 on the swing limit mounting cylinder 1114.

[0040] When splitting bricks: The main driving member 4 drives the locking seat 111 to descend. Since the bricklaying surface is uneven, each main blade 1232 slides in the vertical direction under the clamping of the tool rest clamping plate 1231, driving the plunger 1222 to slide up and down. The upper end of the plunger 1222 abuts against the corresponding lower-side wedge block 12111. Each plunger 1222 conducts the extrusion force of the corresponding main blade 1232 to the corresponding lower-side wedge block 12111. When each lower-side wedge block 12111 is subjected to the extrusion force, it forces itself to contract inward and squeeze the adjacent upper-side wedge block 12112 to slide to both sides. In this way, when the main blade 1232 contacts the uneven bricklaying, it can adaptively move up and down, avoiding uneven force on the bricklaying and greatly improving the quality of brick splitting.

[0041] Due to the unequal heights on the left and right sides of the bricklaying, the tool rest bottom plate 116 squeezes the arc block 113 to slide on the arc surface of the arc groove block 112. Since the axis of the swing pin shaft 115 coincides with the axis of the arc surface, the tool rest bottom plate 116 rotates around the swing pin shaft 115 to adapt to the bricklaying surface, avoiding the bricklaying being split due to uneven force. The swing amplitude of the tool rest bottom plate 116 is limited by the swing limit rod 1181. Under the buffering of the swing buffer member 117, the tool rest bottom plate 116 can automatically return to the original position after completing one brick splitting.

[0042] Swing buffer guide columns 1113 are provided at the lower ends on both sides of the locking seat 111. The swing buffer member 117 is sleeved into the swing buffer guide columns 1113, and both ends of the swing buffer member 117 respectively abut against the locking seat 111 and the tool rest bottom plate 116. Under the limitation of the swing buffer guide columns 1113, the swing buffer member 117 will not come out.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
