DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1-Figure 6 A construction wood cutting device for civil engineering shown in the figure comprises a support mechanism 100, a lifting mechanism 200, an adjustment mechanism 300, and a cutting mechanism 400.

The lifting mechanism 200 is arranged at the bottom of the support plate 101, the adjustment mechanism 300 is arranged at the top of the support plate 101, and the cutting mechanism 400 is arranged at the top of the adjustment mechanism 300.

[0028] The adjustment mechanism 300 includes a fixed side plate 301, one side of the fixed side plate 301 is adapted to be installed with an adjustment motor 302, the output shaft or the conveying end of the adjustment motor 302 is fixedly connected with a screw rod 303, the opposite sides of the two fixed side plates 301 are fixedly installed with a slide rod 304, the outer side of the screw rod 303 is threadedly connected with a slider 305, one side of the slider 305 is fixedly provided with a telescopic plate 306, and the top of the telescopic plate 306 is adapted to be installed with a cylinder 307.

[0029] The fixed side plate 301 is fixedly installed on the top of the support plate 101 , the slider 305 is slidably connected to the outside of the slide bar 304 , and the adjustment motor 302 is located on the top of the support plate 101 .

[0030] The lifting mechanism 200 includes a fixed plate 201 and a hollow leg 205 . A lifting motor 202 is mounted on the top of the fixed plate 201 . A worm 203 is fixedly connected to the output end of the lifting motor 202 . A connecting rod 204 is fixedly provided on one side of the worm 203 .

[0031] A lifting plate 206 is slidingly provided inside the hollow leg 205, and teeth 207 are fixedly provided on one side of the lifting plate 206. A rotating shaft 208 is rotatably connected inside the hollow leg 205, and a gear 209 and a worm gear 210 are fixedly sleeved on the outer surface of the rotating shaft 208.

[0032] The fixed plate 201 is fixedly mounted on one side opposite to the two hollow legs 205 , the lifting plate 206 is fixedly mounted on the bottom of the supporting plate 101 , the gear 209 is meshed with the teeth 207 , and the worm wheel 210 is meshed with the worm 203 .

[0033] When in use, the operation of the adjusting motor 302 is controlled. With the assistance of the fixed side plate 301, the adjusting motor 302 drives the screw rod 303 to rotate, and the screw rod 303 drives the slider 305 to slide on the slide bar 304, controlling the left and right movement of the slider 305 (in the length direction of the support plate), and the operation of the cylinder 307 is controlled again, with the assistance of the telescopic plate 306, thereby driving the cutting mechanism 400 to move forward and backward (in the width direction of the support plate);

[0034] Control the operation of the lifting motor 202, the lifting motor 202 drives the worm 203 to rotate, the worm 203 drives the connecting rod 204 to rotate, and the power is transmitted to another set of operations. At this time, the worm 203 drives the worm wheel 210 to rotate, the worm wheel 210 drives the rotating shaft 208 to rotate inside the hollow leg 205, the rotating shaft 208 drives the gear 209 to rotate, the gear 209 engages with the teeth 207, thereby driving the lifting plate 206 to move upward inside the hollow leg 205. Under the synchronous action of multiple lifting plates 206, the support plate 101 can adjust the height.

[0035] In summary, the height of the device can be controlled by the lifting mechanism 200, so that different people can adapt to the device to process wood. The wood can be processed according to needs through the scale line 102. The cutting mechanism 400 can be moved according to needs through the adjustment mechanism 300, and there is no need to move the wood left and right, thereby reducing the labor intensity of the operator. Through the function of the cutting mechanism 400, the corresponding cutting bevel can be adjusted according to needs, so that the wood can be processed more efficiently.

[0036] Reference Figures 4 to 6 The cutting mechanism 400 includes a supporting side plate 401, and a fixing rod 402 is fixedly connected to the opposite side of the two supporting side plates 401, and a rotating shaft 403 is rotatably connected to the opposite side of the two fixing rods 402. A rotating block 404 is fixedly sleeved on the outer surface of the rotating shaft 403, and a cutting motor 405 is adapted to be installed at the bottom of the rotating block 404.

[0037] The output end of the cutting motor 405 is fixedly connected to the cutting blade 406, a retaining shoe 407 is fixedly installed on one side of the rotating block 404, a hole disk 408 is connected to one side of the rotating shaft 403 by bolts, and an F-shaped block 409 is fixedly provided on one side of the other supporting side plate 401. A limit pin 412 is movably inserted inside the F-shaped block 409, and a limit ring 411 is fixedly sleeved on the outer surface of the limit pin 412.

[0038] A spring 410 is fixedly installed on the opposite sides of the two ear plates of the limiting ring 411 and the F-shaped block 409, an adjusting rod 413 is fixedly set on one side of the hole plate 408, a collecting groove 414 is fixedly set on the top of the support plate 101, and a box body 416 is fixedly connected to the bottom of the support plate 101, and a drawer 415 is inserted into the interior of the box body 416.

[0039] Among them, the supporting side plate 401 is fixedly installed on one side of the telescopic plate 306, the output end of the cylinder 307 is fixedly connected to one side of the supporting side plate 401, the spring 410 is located on the outside of the limit pin 412, the limit pin 412 is adapted to the hole plate 408, the collecting groove 414 is located on one side of the cutting piece 406, and the drawer 415 is adapted to the collecting groove 414.

[0040] When in use, the operation of the cutting motor 405 is controlled, and the cutting motor 405 drives the cutting blade 406 to rotate, so as to cut the wood at the bottom of the cutting blade 406. Under the action of the blocking tile 407, the powder generated during cutting is blocked into the collecting trough 414, and finally the powder falls into the drawer 415. When the powder in the drawer 415 is full, the drawer 415 is pulled out of the box 416 and cleared, and the drawer 415 is installed into the box 416 again.

[0041] When it is necessary to cut an oblique edge on the wood, the limit pin 412 is pulled manually, and the limit pin 412 drives the limit ring 411 to move in the direction away from the hole disk 408; at this time, the spring 410 is compressed, so that the limit pin 412 moves out of the limit hole of the hole disk 408, and the adjusting rod 413 is manually rotated, the adjusting rod 413 drives the hole disk 408 to rotate, the hole disk 408 drives the rotating shaft 403 to rotate, and the rotating shaft 403 drives the rotating block 404 to rotate, thereby driving the cutting motor 405 to tilt at a certain angle. After adjusting the position, under the action of the spring 410, the spring 410 pushes the limit ring 411 to move, thereby inserting the limit pin 412 into the limit hole of the hole disk 408.

[0042] In summary, through the action of the cutting mechanism 400, the degree of rotation of the cutting blade 406 can be adjusted according to the requirements of the cutting angle, without adjusting the angle of the wood, which can reduce the labor intensity of the operator. During cutting, a certain amount of wood powder will be generated. With the assistance of the baffle 407, the powder can be blocked into the collection trough 414, thereby reducing the risk of powder being inhaled into the lungs and improving the cleanliness of the working environment.
