[0046] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0047] As Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 shown, in the embodiment of the present invention, a wood crusher treatment and environmental protection device includes a crushing box 1 and a processing box 2;

[0048] Among them, the crushing box 1 is used for crushing wood;

[0049] The processing box 2 is installed at the tail end of the crushing box 1, and the crushed wood is transported to the processing box 2 for dust removal through the first conveying member. It includes a box body 201, a conveying frame 203 and a dust removal mechanism. The conveying frame 203 is tilted in the box body 201 for conveying the crushed wood. The conveying frame 203 is slidably connected to the inner wall of the box body 201. A vibration component 5 for driving the conveying frame 203 to vibrate back and forth is installed at the bottom of the box body 201. The dust removal mechanism is arranged on the upper side of the conveying frame 203, and includes a dust collecting box 202 and a dust suction component. The dust collecting box 202 is fixedly installed on the top of the processing box 2, and the dust suction component is installed on the upper end of the conveying frame 203. It includes a movable frame 204 and two sets of push plates 209. The two sets of push plates 209 are slidably arranged. Installed on both sides of the conveying frame 203, used to transport the broken wood laid on the side of the conveying frame 203 to the middle, the movable frame 204 is slidably installed on the upper side of the conveying frame 203 along the vertical direction of the bottom plate of the conveying frame 203, and is linearly lifted and lowered by the first driving assembly at the upper end of the conveying frame 203, and two rows of dust collectors 205 are mirror-mounted on the upper end of the conveying frame 203, and the two rows of dust collectors 205 are connected to the dust collecting box 202 through corresponding dust suction pipes, and the two rows of dust collectors 205 are slidably installed on the movable frame 204 through corresponding installation sliders 206, and are driven to reciprocate in mirror image by the second driving assembly 207 on the movable frame 204, and the two groups of push plates 209 are transmission-connected to the second driving assembly 207 through the transmission assembly 6, and the two groups of push plates 209 move synchronously with the two rows of dust collectors 205;

[0050] Specifically, in the present invention, after the wood is further crushed by the crushing box 1, the crushed wood is discharged through the discharge port at the bottom, and the crushed wood is transported to the processing box 2 through the first conveying member. The first conveying member in the present invention is the first conveyor belt 3, and the crushed wood is continuously transported to the processing box 2 through the first conveyor belt 3. Correspondingly, a second conveyor belt 4 is installed at the tail of the processing box 2 for transporting the dust-removed wood outward. The present invention can perform continuous dust removal operations on the continuously transported crushed wood.

[0051] like Figure 5 As shown, in the embodiment of the present invention, the vibration assembly 5 includes multiple groups of guide rods 506, reset springs 504 and rotary cams 501. The multiple groups of guide rods 506 are fixedly installed at the bottom of the conveying frame 203 and are slidably connected with the guide sleeve ring 505 fixedly installed on the inner wall of the box body 201. The reset spring 504 is arranged on the corresponding guide rod 506, one end of which is fixedly connected to the guide sleeve, and the other end is fixedly connected to the bottom end of the guide rod 506. The rotary cam 501 is rotatably installed on the box body 201 through a rotary shaft, and the rotary shaft is driven to rotate by the rotary motor 502. The side of the rotary cam 501 abuts against the protruding arc block 503 installed at the bottom of the conveying frame 203.

[0052] When the vibration assembly 5 in the present invention performs the vibration operation of the conveying frame 203, the rotary motor 502 drives the rotary shaft to rotate at a constant speed, and drives the rotary cam 501 coaxially installed on the rotary shaft to rotate. In the present invention, the rotary cam 501 is a cam structure with convex ends at both ends, so that one rotation period can drive the conveying frame 203 to perform two cycles of reciprocating movement. At the same time, during the rotation, the guide rod 506 at the bottom of the conveying frame 203 is slidably matched with the guide ring to guide the linear movement of the conveying frame 203. And during the guiding and sliding process, through the elastic expansion and contraction of the return spring 504, the protruding arc block at the bottom of the conveying frame 203 is always kept in contact with the side surface of the rotary cam 501. In the present invention, the broken wood placed therein is driven by the conveying frame 203 to perform vibration and collision, the dust on the surface of the wood is vibrated and lifted, and the lifted dust is sucked and collected by the dust suction assembly located at the upper end of the conveying frame 203. At the same time, some dust with larger particles moves downward to the bottom of the conveying frame 203 during the vibration process, and such dust is collected by the downwardly moving vacuum cleaner 205.

[0053] As Figure 3 and Figure 6 shown, in the embodiment of the present invention, the first driving assembly includes a plurality of telescopic cylinders 7. The cylinders of the plurality of telescopic cylinders 7 are fixedly installed on the upper end of the conveying frame 203 through a mounting plate, and the ends of their telescopic rods are fixedly connected to the movable frame 204. When it is necessary to control the vacuum cleaner 205 to move downward to collect the dust at the bottom of the conveying frame 203, the telescopic cylinder 7 extends, driving the movable frame 204 to move towards the bottom of the conveying frame 203, driving a plurality of vacuum cleaners 205 to move to the low-position dust suction position;

[0054] Further, as Figure 7 、 Figure 8 and Figure 9As shown in the figure, the vacuum cleaner 205 includes an air duct 2051, a rotary pipe 2052, a suction plate 2054, a suction pipe 2055, a transmission gear 2053, and a fixed rack 2056. The air duct 2051 is slidably mounted on the movable frame 204 through a mounting slider 206, and its upper end is communicated with the dust collection box 202 through a suction pipe. The rotary pipe 2052 is rotatably mounted at the bottom of the air duct 2051, and a transmission gear 2053 is coaxially and fixedly mounted on the outer side of its pipe body. The transmission gear 2053 meshes with and drives the fixed rack 2056 fixedly mounted on the movable frame 204. The suction plate 2054 is fixedly mounted at the bottom of the rotary pipe 2052, and a plurality of groups of air inlet holes are formed on its side. A plurality of suction pipes 2055 are fixedly mounted in a cross shape in the mounting holes at the bottom of the suction plate 2054, and air inlet holes are provided at both its bottom and side. In the present invention, the second driving assembly 207 drives two rows of vacuum cleaners 205 to reciprocate linearly, and during the movement, the transmission gear 2053 on the outer side of the rotary pipe 2052 meshes with and drives the fixed rack 2056 on the movable frame 204, driving the rotary pipe 2052 and the suction plate 2054 at its bottom to rotate;

[0055] Specifically, when the movable frame 204 is at the high position of the conveying frame 203, the vacuum cleaner 205 driven to reciprocate by the second driving assembly 207 at this time can suck and collect the dust raised by the vibration of the wood. The dust is mainly sucked and collected through the air inlet holes on the side of the suction plate 2054. When the movable frame 204 is driven by the telescopic cylinder 7 to move downward, the suction pipes 2055 at the bottom of the suction plate 2054 can be inserted into the gaps between the broken woods, and the debris sinking to the bottom of the conveying frame 203 is sucked and collected. During the rotation of the suction plate 2054, the cross-shaped arranged suction pipes 2055 are used to clean and suck the bottom plate of the conveying frame 203.

[0056] As Figure 7 As shown in the figure, in the embodiment of the present invention, the second driving assembly 207 includes a plurality of groups of double threaded rods 2071, a sprocket assembly 208, and a driving motor 2072. A plurality of groups of double threaded rods 2071 are rotatably mounted in parallel in the movable frame 204, and a set of external threads are mirror-symmetrically arranged on both sides thereof. The two sets of external threads form a screw drive with the corresponding mounting sliders 206. The plurality of groups of double threaded rods 2071 are connected by a sprocket assembly 208. The end of one group of double threaded rods 2071 is coaxially driven and connected to the driving motor 2072 mounted on the movable frame 204. In the present invention, when a driving motor 2072 is started, the corresponding double threaded rod 2071 is driven to rotate, and the plurality of groups of double threaded rods 2071 are driven to rotate synchronously by the sprocket assembly 208. Through the screw drive between the mounting slider 206 and the external thread, the two vacuum cleaners 205 mounted on the same group of double threaded rods 2071 move mirror-symmetrically;

[0057] Among them, the sprocket assembly 208 includes a driven sprocket 2082 and a transmission chain 2081. Multiple sets of driven sprockets 2082 are coaxially installed on the ends of the corresponding double-threaded rods 2071, and the multiple sets of driven sprockets 2082 are connected through the transmission chain 2081. The synchronous rotation of the multiple sets of double-threaded rods 2071 is achieved through the transmission of the driven sprocket 2082 and the transmission chain 2081. Of course, in actual design, the driven sprocket 2082 and the transmission chain 2081 can also be replaced by other components with synchronous transmission rotation, such as other worm gear structures, etc.

[0058] like Figure 3 , Figure 4 as well as Figure 6 As shown, in the embodiment of the present invention, the two groups of push plates 209 are connected to the second drive assembly 207 through the transmission assembly 6, so that the two groups of push plates 209 can move synchronously with the two rows of vacuum cleaners 205, and the two groups of push plates 209 are mirror-imaged and close to each other, so that the broken wood on the edges of both sides of the conveying frame 203 is conveyed to the middle, so that the vacuum cleaner 205 can collect the dust;

[0059] Furthermore, the transmission assembly 6 includes a rotating rod 601, a telescopic connecting rod 602, a driving screw 603 and a rotating inner nut 604. The rotating rod 601 is coaxially fixedly connected to the end of the corresponding double-threaded rod 2071 through a coupling, and is rotatably connected to the first slide 607 slidably installed on the side of the movable frame 204. The driving screw 603 is fixedly installed on the outer side of the corresponding push-pull plate and passes through the second slide 608 slidably installed on the box body 201. The driving screw 603 and the rotating inner nut 604 rotatably installed on the second slide 608 form a spiral pair transmission. The two ends of the telescopic connecting rod 602 are respectively rotatably installed with the first slide 607 and the second slide 608. The double-threaded rod 2071 is equipped with a bevel gear set at both ends, which respectively rotates and connects the rotating rod 601 and the rotating inner nut 604. In the present invention, when the double-threaded rod 2071 rotates, the rotating rod 601 installed at its end can be driven to rotate synchronously, and the rotating inner nut 604 on the second slide plate 608 is driven to rotate by the rotation transmission of the two sets of bevel gear sets and the telescopic connecting rod 602, and the spiral transmission drives the driving screw 603 and the push plate 209 to move synchronously. At the same time, the telescopic connecting rod 602 with a retractable length is used to ensure that when the movable plate moves, at different working heights, the telescopic connecting rod 602 can maintain the rotation transmission state between the rotating inner nut 604 and the rotating rod 601.

[0060] Among them, the bevel gear set includes a driven bevel gear 605 and two sets of driving bevel gears 606. The two sets of driven bevel gears 605 are coaxially installed on the outer sides of the rotary rod 601 and the rotary inner nut 604 respectively. The two sets of driving bevel gears 606 are coaxially installed at both ends of the telescopic connecting rod 602 and are meshed with the corresponding driven bevel gears 605 for transmission. At the same time, the first slide plate 607 and the second slide plate 608 designed in the present invention can correspondingly seal the communication holes opened on the side walls of the box body 201 and the conveying frame 203 when the rotary rod 601 and the driving screw 603 are installed, so as to prevent dust from being sent outward through the communication holes.

[0061] In summary, in the present invention, a conveying frame 203 and a dust removal mechanism are arranged in the box body 201 of the processing box 2. At the same time, the obliquely arranged conveying frame 203 can continuously convey the broken wood. At the same time, the rotary motor 502 drives the rotary cam 501 to rotate continuously, driving the conveying frame 203 to vibrate reciprocally, so that the broken wood vibrates and collides during the conveying process, vibrating and raising the dust on the surface of the wood. During the vibration process, some dust particles with larger particles move downward to the bottom of the conveying frame 203.

[0062] At the same time, during the vibration of the conveying frame 203, the movable frame 204 can move alternately between the working high position and the working low position according to the setting by the telescopic cylinder 7. When the telescopic cylinder 7 contracts to drive the movable frame 204 to move to the high position, at this time, the two rows of dust collectors 205 are driven to linearly reciprocate by the rotation of the multi-group double threaded rods 2071, and the dust raised by the vibration of the wood can be vacuumed and collected. The dust is mainly vacuumed and collected through the air inlet holes on the side of the suction disc 2054. When the movable frame 204 moves downward to the working low position by the elongation of the telescopic cylinder 7, at this time, the suction pipe 2055 located at the bottom of the suction disc 2054 can be inserted into the gap between the broken wood, and the debris that has sunk to the bottom of the conveying frame 203 can be vacuumed and collected. At the same time, the cross-shaped arranged suction pipes 2055 can follow the rotation of the suction disc 2054 to clean and vacuum the bottom plate of the conveying frame 203. At the same time, the pushing plates 209 on both sides of the conveying frame 203 can move synchronously with the dust collectors 205 while the two rows of dust collectors 205 linearly reciprocate, and push the broken wood located at the two side edges of the conveying frame 203 to the middle for the dust collectors 205 to vacuum and collect the dust.

[0063] In this solution, a controller is also provided. The controller is set on the device. When in use, each electrical device can be started to operate through the controller. The power connection method of each electrical device is an existing mature technology, and the control circuit of the controller can be realized by simple programming by those skilled in the art, which are all well-known technologies to those skilled in the art and will not be elaborated here.

[0064] The above describes the preferred embodiments of the present invention in detail. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
