Technical Field

[0001] The invention relates to the technical field of forest waste treatment, in particular to a forest waste double-shaft shearing type crusher and an adaptive adjustment device thereof. Background Art

[0002] Forestry waste treatment refers to the collection, transportation, processing, and resource utilization of organic waste, such as branches, bark, sawdust, and fallen leaves, generated during forestry production, processing, and use. Its goal is to reduce environmental pollution and achieve efficient waste conversion. Common methods include incineration for power generation, composting, biomass energy production, and material recycling. Scientific treatment can increase resource recycling rates, reduce carbon emissions, and promote sustainable forestry development, while balancing ecological and economic benefits. This process must comply with environmental regulations and optimize treatment paths based on technical and economic considerations.

[0003] In the process of forest waste treatment, crushing is one of the key links. Traditional double-shaft shearing crushers usually use conveyor belts to transport materials.

[0036] Example 1

[0037] Reference Figure 1-5 , as a first embodiment of the present invention, provides an adaptive adjustment device, which includes,

[0038] The pressing component 210 includes a compression component 211 for adaptively pressing forest waste, a cleaning component 212 for cleaning the pressing component 210, a replacement component 213 for processing different forest wastes, and an anti-stuck component 214 for preventing the compression component 211 from getting stuck;

[0039] The anti-rebound component 220 includes a mounting frame 221, a plurality of rebound hinges 222 fixedly mounted on the top of the mounting frame 221, a plurality of baffles 223 rotatably mounted on the surface of the rebound hinges 222 and used to prevent forest waste from rebounding and flying out, and a plurality of blocks 224 fixedly mounted on the top of the mounting frame 221 and used to block and limit the baffles 223.

[0040] Among them, the compression member 211 is used to compress the forest waste, which can compress the fluffy forest waste so that the forest waste can be pushed into the double-axis shearing crusher 110 for crushing, preventing blockage and affecting feeding; the cleaning member 212 is used to clean the compression member 211 to prevent the compression member 211 from adhering to a large amount of bark sap or vines, which affects its compression effect on the forest waste; the replacement member 213 is used to facilitate the replacement of the compression member 211 so that the compression member 211 can adapt to different types of forest waste; the anti-stuck member 214 is used to urgently rise the compression member 211 to prevent larger tree trunks from pressing against the compression member 211 and making it unable to press the forest waste.

[0041] Specifically, the compression member 211 includes a fixed frame 2111, a movable frame 2112 slidably installed on the inner side of the fixed frame 2111, a plurality of first springs 2113 arranged on the inner side of the fixed frame 2111 and used to maintain elastic force on the movable frame 2112, and a pressing roller 2114 rotatably installed on the inner side of the movable frame 2112 and used to press forest waste.

[0042] Among them, the first spring 2113 is used to maintain the squeezing of the movable frame 2112, so that the movable frame 2112 drives the pressing roller 2114 to press down, and then the pressing roller 2114 can adaptively press the forest waste, so that fluffy branches or branches with many branches can be easily pushed into the interior of the double-axis shearing crusher 110, avoiding the feed port of the double-axis shearing crusher 110 from being blocked.

[0043] Furthermore, a limiting slot is provided on the inner side of the fixed frame 2111, and a limiting block is provided on the surface of the movable frame 2112 for use with the limiting slot, and the limiting block is slidably installed inside the limiting slot.

[0044] The cooperation between the limiting slide and the limiting block is used to limit the movable frame 2112 so as to improve the pressing effect of the pressing roller 2114 on the forest waste.

[0045] During use, the transmission belt 120 is used to transport forest waste. When the forest waste is transported to the bottom of the pressing component 210, the elastic force of several first springs 2113 maintains pressure on the movable frame 2112, and the movable frame 2112 drives the pressing roller 2114 to press the forest waste being transported, so that the fluffy forest waste is compressed, making it easy for the forest waste to be pushed into the interior of the double-axis shearing crusher 110 for crushing.

[0046] In summary, the compression member 211 is used to compress the forest waste, so that the fluffy forest waste can be compressed so that the forest waste can be pushed into the double-shaft shearing crusher 110 for crushing, thereby preventing blockage and affecting feeding.

[0047] Example 2

[0048] Reference Figure 6-11 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the cleaning member 212 includes a plurality of second springs 2121 fixedly installed on the inner side of the movable frame 2112, a movable plate 2122 fixedly installed on the end surface of the second spring 2121, a scraper 2123 fixedly installed on the bottom of the movable plate 2122 and used for scraping bark sap or vines attached to the surface of the pressing roller 2114, and a cleaning brush plate 2124 for secondary cleaning of the surface of the pressing roller 2114.

[0049] Among them, the second spring 2121 is used to keep the movable plate 2122 pressed, and then the movable plate 2122 drives the scraper 2123 and the cleaning brush plate 2124 to fit the surface of the pressing roller 2114, so that the scraper 2123 scrapes the bark juice or vines on the surface of the pressing roller 2114, and the cleaning brush plate 2124 cleans the surface of the guide rod 2144, so as to achieve the cleaning effect of the surface of the pressing roller 2114.

[0050] Specifically, two positioning rods 2125 for limiting the position of the movable plate 2122 are fixedly installed on the top of the movable plate 2122, and two positioning holes for the positioning rods 2125 to pass through are defined on the top of the movable frame 2112.

[0051] Among them, the cooperation between the positioning rod 2125 and the positioning hole is used to limit the movable plate 2122 to prevent the movable plate 2122 from being affected by the rotation of the pressing roller 2114 and being offset, thereby improving the cleaning effect of the scraper 2123 and the cleaning brush plate 2124 on the surface of the pressing roller 2114.

[0052] Furthermore, the scraper 2123 is arranged at an angle, and a baffle is fixedly installed on the surface of the scraper 2123 to prevent bark sap or vines from adhering to the surface of the scraper 2123 , and the cleaning brush plate 2124 is in contact with the nip roller 2114 .

[0053] The baffle plate prevents the scraped bark sap or vines from adhering to the surface of the scraper 2123 and affecting the cleaning effect of the nip roller 2114 .

[0054] Preferably, the replacement part 213 includes a plurality of reserved grooves 2131 opened at the top of the fixing frame 2111, a mounting cylinder 2132 arranged inside the reserved groove 2131, a mounting groove 2133 opened on the inner wall of the reserved groove 2131, a card slot 2134 opened at the bottom of the reserved groove 2131, and a card block 2135 fixedly installed on the surface of the mounting cylinder 2132 and carded in the card slot 2134.

[0055] Among them, the bottom of the mounting cylinder 2132 is fixedly connected to the first spring 2113, and the mounting groove 2133 and the clamping groove 2134 are respectively adapted to the size of the clamping block 2135. Through the cooperation between the reserved groove 2131, the mounting cylinder 2132, the mounting groove 2133, the clamping groove 2134 and the clamping block 2135, the first spring 2113 is replaced to facilitate the processing of different tree species such as hardwood or softwood, and the first spring 2113 with different pressure parameters can be adjusted and replaced according to different tree species.

[0056] Furthermore, a clamping plate 2136 is fixedly mounted on the bottom end surface of the first spring 2113 , and a clamping groove 2137 for cooperating with the clamping plate 2136 for positioning is formed on the top of the movable frame 2112 .

[0057] The cooperation between the clamping plate 2136 and the clamping groove 2137 is used to position and install the first spring 2113 when it is replaced, so as to avoid installation deviation of the first spring 2113.

[0058] Furthermore, the anti-stuck component 214 includes two lifting blocks 2141 fixedly installed at the bottom of the fixed frame 2111, a motor 2142 for driving the fixed frame 2111 to rise and fall, a screw rod 2143 fixedly installed at the output end of the motor 2142 and threadedly connected to the lifting block 2141, two guide rods 2144 for limiting the lifting block 2141, and a control box 2145 for controlling the start of the motor 2142.

[0059] The screw rod 2143 and the guide rod 2144 respectively pass through the lifting block 2141, and the output end of the control box 2145 is electrically connected to the input end of the motor 2142;

[0060] It should be noted that a micro switch is embedded inside the limiting slide groove on the inner side of the fixed frame 2111. In extreme cases, when the tree trunk presses against the pressing roller 2114 and cannot be pressed down, the tree trunk will collide with the pressing roller 2114, thereby driving the slider to press the micro switch. The control box 2145 receives the signal from the micro switch and starts the motor 2142 to make the pressing roller 2114 rise and separate from the tree trunk, avoiding damage to the pressing roller 2114.

[0061] During use, when the pressing roller 2114 presses the forest waste, bark sap and vines are easily adhered to its surface. The second spring 2121 squeezes the movable plate 2122, and the movable plate 2122 pushes the scraper 2123 and the cleaning brush plate 2124 to fit the surface of the pressing roller 2114. The scraper 2123 scrapes the bark sap and vines on the surface of the pressing roller 2114, and the cleaning brush plate 2124 cleans the surface of the pressing roller 2114 again.

[0062] When pressing different types of forest waste, it is necessary to replace the first spring 2113 with different pressure parameters. When replacing, it is necessary to press the installation cylinder 2132 downward so that the installation cylinder 2132 drives the clamping block 2135 out of the clamping groove 2134, and rotate it so that the installation cylinder 2132 drives the clamping block 2135 to rotate out of the installation groove 2133. At this time, under the elastic force of the first spring 2113, the installation cylinder 2132 is ejected from the reserved groove 2131. At this time, the installation cylinder 2132 and the first spring 2113 are taken out as a whole.

[0063] Then install the required first spring 2113, insert the installation cylinder 2132 into the reserved groove 2131, insert the clamping plate 2136 into the locking groove 2137, align the clamping block 2135 with the installation groove 2133 and insert it. Press the installation cylinder 2132 so that the clamping block 2135 moves out of the installation groove 2133. At this time, rotate the installation cylinder 2132, which drives the clamping block 2135 to rotate to the locking groove 2134. Release the installation cylinder 2132, and the elastic force of the first spring 2113 will cause the installation cylinder 2132 to bounce upward, so that the clamping block 2135 is locked in the inside of the locking groove 2134, completing the replacement of the first spring 2113.

[0064] A micro switch is embedded inside the limiting slide groove on the inner side of the fixed frame 2111. In extreme cases, when the tree trunk presses against the pressing roller 2114 and cannot be pressed down, the tree trunk collides with the pressing roller 2114, thereby driving the slider to press the micro switch. The control box 2145 receives the signal from the micro switch and starts the motor 2142 to cause the pressing roller 2114 to rise and separate from the tree trunk.

[0065] In summary, the cleaning part 212 is used to clean the compression part 211 to prevent the compression part 211 from adhering to a large amount of bark sap or vines, which affects its compression effect on forest waste; the replacement part 213 is used to facilitate the replacement of the compression part 211 so that the compression part 211 can adapt to different types of forest waste; the anti-stuck part 214 is used to urgently raise the compression part 211 to prevent larger tree trunks from pressing against the compression part 211 and making it unable to compress the forest waste.
