Description

Technical Field

[0001] This invention relates to a humidification device, specifically a humidification device for the feed inlet of a wood chipper. Background Technology

[0002] The main raw materials used in wood shaving machines are purchased during winter and spring. In some cases, the wood is not used immediately after purchase, and its moisture content decreases after the high temperatures of summer. Raw materials with too low moisture content are difficult to shaving, affecting the processing efficiency of the wood shaving machine. Furthermore, raw materials with low moisture content are more likely to generate dust, polluting the environment. Currently, existing wood shaving machines do not have built-in humidification devices and cannot humidify the raw materials.

[0003] Existing external humidification devices cannot simultaneously perform shaving and humidification. Furthermore, because these devices are not specifically designed for shaving machines, the moisture content of the raw materials may remain low after humidification, or it may be too high, affecting the hardness of the raw materials during shaving and consequently impacting the quality of the shavings. In addition to these two issues, uneven humidification can lead to some raw materials having excessively low moisture content while others have excessively high moisture content, severely impacting processing efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a humidification device at the feed inlet of a wood shaving machine, which can effectively solve the technical problems of low wood shaving efficiency and easy dust generation caused by low moisture content of raw materials.

[0011] The outer wall of the power drum is provided with a first limiting groove and a second limiting groove. Both the first limiting groove and the second limiting groove penetrate the side wall of the power drum. The first limiting groove and the second limiting groove are distributed in an "X" shape. The first limiting groove or the second limiting groove is slidably connected to the power rod.

[0012] Preferably, the rotating telescopic structure also includes a limiting wheel, and protruding plates are fixedly connected to both sides of the power drum. The protruding plates have limiting ports, which are located at the beginning and end of the first limiting groove and the second limiting groove, and connect the first limiting groove and the second limiting groove to the outside of the power drum.

[0013] The center of the limiting wheel is connected to the power shaft. The limiting wheel is located inside the limiting port and slides within the limiting port.

[0014] Preferably, the rotating arm includes a water pipe connecting arm and a rotating rod. One end of the water pipe connecting arm and one end of the rotating rod are fixedly connected and are perpendicularly distributed. The other end of the water pipe connecting arm is connected to the water spray bar. The rotating rod is inserted into the power rotating drum and rotates synchronously with the power rotating drum. The other end of the rotating rod is connected to the connecting rod.

[0015] Preferably, the connecting rod includes a first short rod, a connecting shaft, and a second short rod;

[0016] The first short rod has an integrally formed locking part at one end, which engages with the rotating arm; the other end of the first short rod is connected to one end of the second short rod via a connecting shaft, and the included angle between the first short rod and the second short rod is fixed; the other end of the second short rod extends with a protrusion, which is located in a groove.

[0017] Preferably, the limiting wheel includes a connecting plate and an arc-shaped limiting plate;

Both ends of the connecting plate are fixedly connected to arc-shaped limiting plates, which slide within the limiting opening.

[0019] Preferably, it also includes a fixing structure, which includes a first fixing structure, a second fixing structure and a third fixing structure, all of which are fixedly connected to the side wall at the feed inlet of the wood chipper.

[0020] The first fixed structure is rotatably connected to both ends of the power drum;

[0021] The second fixed structure is rotatably connected to the power shaft;

[0022] The third fixing structure is located between the first short rod and the second short rod, and the third fixing structure is rotatably connected to the connecting shaft.

[0023] The beneficial effects achieved by this invention are as follows:

[0024] 1. Compared to installing the humidifier in other locations, this invention places the humidifier at the feed inlet of the wood chipper, which allows for more even water spraying. The water spraying point is a spray bar with nozzles mounted on it, further improving the uniformity of the spray. The rotating telescopic structure can move the nozzles along the spray path.

[0025] 2. The spray head incorporates a suspension structure. When water supply to the spray head stops, the suspension device slides down under gravity, draining the water from the spray head. The bottom of the suspension device then contacts the elastic structure, allowing the needle to insert into the through-hole and effectively clean any adhering dirt, preventing blockage. When the solenoid valve opens and water supply begins, the suspension device rises under the buoyancy of the water, expelling air from the vent until the top of the suspension device is completely flush with the inner wall of the top cover, sealing the vent. If air enters the spray head, it is expelled through the vent, preventing unstable water spray and ensuring a uniform spray effect.

[0026] 3. When the bottom of the suspension device directly contacts the base shell, the contact area is too large, which may cause the suspension device to stick to the base shell, thus affecting the use of the nozzle. This invention adds an elastic structure between the suspension device and the base shell, effectively preventing the suspension device from sticking. Furthermore, when the suspension device falls, the elastic structure allows it to perform small-amplitude reciprocating motions, thereby improving the effectiveness of the needle in removing dirt from through-holes.

[0027] 4. The stopper plate serves to position the suspension structure and also helps to better seal the vent. The nozzle's inlet pipe extends all the way to the bottom shell, with the inlet holes located on the inlet pipe. When water enters the nozzle, as the suspension device moves upward, the number of inlet holes above the suspension device gradually decreases, while the number of inlet holes below the suspension device gradually increases. This prevents all the water entering the nozzle from falling onto the top of the suspension device, thus affecting its buoyancy and avoiding excessive water leakage from the vent, which would cause unnecessary waste.

[0028] 5. The water inlet pipe is equipped with a guide groove, and the suspension device is equipped with a guide block that cooperates with the guide groove. This can prevent the suspension device from deviating during the lifting process, prevent the needle from failing to enter the through hole, and prevent the plug plate from failing to enter the vent.

[0029] 6. The rotating telescopic structure can drive the spray bar to rotate periodically, which can make the nozzle cover a larger area, improve the spraying efficiency, and prevent the nozzle from spraying the same area repeatedly. The rotating telescopic structure can also drive the spray bar to perform periodic telescopic movements, further increasing the coverage area of ​​the nozzle and ensuring that the area between adjacent nozzles is also effectively sprayed.

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] like Figures 1-7As shown, a humidification device at the feed inlet of a wood chipper includes a main water inlet pipe 1, with branch water inlets 2 connected to the main water inlet pipe 1. Preferably, the diameter of the main water inlet pipe 1 is larger than the diameter of the branch water inlets 2, ensuring that one main water inlet pipe 1 can simultaneously supply water to multiple branch water inlets 2. The branch water inlets 2 can be divided into vertical pipes and horizontal pipes, connected by a bend. A pressure gauge 7, a manual valve 8, a pressure sensor 9, and a solenoid valve 10 are sequentially connected to the horizontal pipe, and a flexible connecting pipe 3 is connected to the end of the horizontal pipe. A spray bar 4 is connected to the end of the flexible connecting pipe 3, and a rotating telescopic structure 5 is fixedly connected to both ends of the spray bar 4. The rotating telescopic structure 5 can fix the spray bar 4 at the feed inlet of the wood chipper, and a nozzle 6 is also connected to the spray bar 4.

[0048] The nozzle 6 includes a lower housing 61, an upper housing 62, and a suspension structure 63. The lower housing 61 and the upper housing 62 are detachably connected. The connection between the lower housing 61 and the upper housing 62 needs to be well sealed and leak-proof. The suspension structure 63 is slidably connected to the lower housing 61.

[0049] like Figure 5 As shown, the lower housing 61 includes a bottom shell 611, which has a through hole 612 for spraying water. A water inlet pipe 613 is also fixedly connected to the middle portion of the bottom shell 611. Preferably, the bottom shell 611 and the water inlet pipe 613 are coaxially aligned. The water inlet of the water inlet pipe 613 is sealed to the spray bar 4 (the water inlet of the water inlet pipe 613 refers to the end of the water inlet pipe 613 away from the lower housing 61), thereby supplying water to the water inlet pipe 613. A water inlet hole 614 is provided on the side wall of the water inlet pipe 613 (in this embodiment, the water inlet hole 614 is a through hole 612 for allowing water to flow from the water inlet pipe 613 into the nozzle 6). A guide groove 615 is also provided on the side wall of the water inlet pipe 613, extending along the axial direction of the water inlet pipe 613. An elastic structure 616, which can be a spring, is fitted onto the water inlet pipe 613. A first side wall 617 extends from the edge of the bottom shell 611.

[0050] The suspension structure 63 is made entirely of a material with a density less than water (in this embodiment, the suspension structure 63 is made of polyethylene), such as Figure 6 As shown, the suspension structure 63 includes a suspension plate 631 with an installation opening 632. A guide block 633 is fixedly connected inside the installation opening 632. The guide block 633 works in conjunction with a guide groove 615 and can be positioned and slid within the guide groove 615. A stopper plate 634 is provided at the top of the suspension plate 631, and a needle 635 is provided at the bottom of the suspension plate 631. The needle 635 includes a column fixed to the bottom of the suspension plate 631 and a tip integrally formed with the bottom of the main body. The length of the column is not less than the length of the elastic structure 616, thereby ensuring that the tip can extend out of the through hole 612. The number of needles 635 is the same as the number of through holes 612.

[0051] like Figure 4 As shown, when installing the lower housing 61 and the suspension structure 63, the guide block 633 is inserted into the guide groove 615, and at this time the water inlet pipe 613 is inserted into the installation port 632.

[0052] like Figure 7 As shown, the upper housing 62 includes a top cover 621, with a second sidewall 622 extending from the edge of the top cover 621. The second sidewall 622 has a detachable mounting structure that can mate with the first sidewall 617. This detachable mounting structure can be any known prior art, as long as it ensures that the connection between the second sidewall 622 and the first sidewall 617 is sealed and leak-proof. The top cover 621 has an opening 623 for accommodating a water inlet pipe 613. After installation, the water inlet pipe 613 passes through the opening 623. The top cover 621 also has an exhaust port 624. As a preferred embodiment, the exhaust ports 624 are distributed in a ring shape, and the exhaust ports 624 can be distributed in multiple layers outward from the center of the top cover 621. In use, when the top of the suspension plate 631 is attached to the top cover 621, all exhaust ports 624 are completely sealed. At this time, the plug plate 634 can enter the exhaust port 624 and block the corresponding exhaust port 624, keeping the exhaust port 624 sealed. As a preferred solution, the number of plug plates 634 is less than the number of exhaust ports 624. The plug plate 634 can not only partially seal the exhaust port 624, but also limit the position, thereby preventing the suspension structure from changing position due to vibration and swing during operation, and thus preventing the suspension structure 63 from failing to completely seal the exhaust port 624.

[0053] To ensure the levitation structure 63 can float smoothly, water inlets 614 of appropriate size and number are required. The water inlet flow rate of the water inlets 614 should be greater than the water leakage flow rate of the through-hole 612. Additionally, the length of the needle 535 can be appropriately increased so that water only leaks from the through-hole 612 after the levitation structure 63 has floated to a certain height. When the levitation structure 63 rises to the top of the nozzle 6, the water leakage flow rate of the through-hole 612 equals the water inlet flow rate of the water inlets 614.

[0054] In operation, first install the humidifying device at the feed inlet of the wood chipper. Open the solenoid valve 10 and the manual valve 8. Water flows from the main water inlet pipe 1 into the branch water inlet pipe 2, then into the spray bar 4, and finally into the nozzle 6. Water flows into the nozzle 6 from the inlet pipe 613. At this time, the bottom of the elastic structure 616 is in contact with the bottom shell 611, the top of the elastic structure 616 is in contact with the suspension plate 631, and the needle 635 is inserted into the through hole 612. When water enters the internal space of the nozzle 6, the suspension structure 63 floats up along the inlet pipe 613 under the action of buoyancy until the top of the suspension plate 631 is completely in contact with the exhaust port 624 and completely seals the exhaust port 624. At this time, the plug plate 634 blocks part of the exhaust port 624. During operation, the operator can manually adjust the manual valve 8 according to the reading of the pressure gauge 7 to ensure that the water flow meets the normal working requirements.

[0055] After the wood chipper stops working, the solenoid valve 10 is closed. The water in the nozzle 6 gradually decreases, and the suspension structure 63 descends along the water inlet pipe 613 under the action of gravity. When the water in the nozzle 6 has all leaked out, the suspension plate 631 contacts the elastic structure 616 and makes a small reciprocating motion under the action of the elastic structure 616. When the elastic structure 616 stops moving, the needle 635 is inserted into the through hole 612, which can effectively prevent the floating and sinking parts from combining with the water droplets at the through hole 612, thereby preventing the through hole 612 from becoming blocked.

[0056] To achieve better spraying results and more even water distribution at the feed inlet of the wood shavings machine, such as... Figures 8-13 As shown, the rotating telescopic structure 5 includes a rotating arm 51, a power rotating drum 52, a connecting rod 53, a cam 54, a power rotating shaft 55, a power rod 56, a limiting rotating wheel 57, a first fixed structure 11, a second fixed structure 12, and a third fixed structure 13.

[0057] The rotating arm 51 includes a water pipe connecting arm 511 and a rotating rod 512. One end of the water pipe connecting arm 511 is connected to the water spray bar 4; the other end of the water pipe connecting arm 511 is fixedly connected to one end of the rotating rod 512. Preferably, the water pipe connecting arm 511 and the rotating rod 512 are perpendicularly distributed. Part of the rotating rod 512 is inserted into the power rotating drum 52. The connection method between the rotating rod 512 and the power rotating drum 52 can be any of the existing technologies, as long as the rotating rod 512 can rotate synchronously with the power rotating drum 52 and can extend and retract within the power rotating drum 52. For example, a limiting groove distributed along the cylinder axis can be opened on the inner wall of the power rotating drum 52, and a limiting protrusion distributed along the rod axis can be added to the rotating rod 512, allowing the limiting groove and the limiting protrusion to slide together. The other end of the rotating rod 512 is connected to the connecting rod 53.

[0058] The connecting rod 53 includes a first short rod 531, a connecting shaft 533, and a second short rod 532. One end of the first short rod 531 has an integrally formed engaging portion 5311, which engages with the rotating rod 512. As a connection method between the engaging portion 5311 and the rotating rod 512, the end of the rotating rod 512 away from the water pipe connecting arm 511 has an annular limiting groove. The engaging portion 5311 can be a "U"-shaped structure, with a limiting protrusion facing the "U"-shaped opening, and the limiting protrusion is located within the annular limiting groove. The other end of the first short rod 531 is connected to one end of the second short rod 532 via the connecting shaft 533. In this connection relationship, it is necessary to ensure that the included angle between the first short rod 531 and the second short rod 532 is fixed. The other end of the second short rod 532 extends with a protrusion, which is located within a groove 541 in the cam 54. At this time, the connecting shaft 533 is connected to the third fixing structure 13. The third fixing structure 13 is existing technology. It is only necessary to ensure that the third fixing structure 13 can fix the connecting shaft 533 at a suitable position at the feed inlet of the wood chipper and ensure that the connecting shaft 533 can rotate freely. It will not be described in detail here. At this time, both the first short rod 531 and the second short rod 532 can rotate with the connecting shaft 533 as the rotation point.

[0059] like Figure 13 As shown, the power shaft 55 is inserted at the center of the cam 54, and the power shaft 55 can drive the cam 54 to rotate synchronously. The power shaft 55 is connected to the second fixing structure 12, which fixes the power shaft 55 at a suitable position at the feed inlet of the wood chipper, at which time the power shaft 55 can rotate freely. A power rod 56 is sleeved on the top of the power shaft 55. The power rod 56 is elliptical cylindrical and can rotate synchronously with the power shaft 55. The power rod 56 can slide in the limiting groove opened in the outer wall of the power drum 52.

[0060] like Figure 12 As shown, the limiting groove includes a first limiting groove 521 and a second limiting groove 522. Both the first limiting groove 521 and the second limiting groove 522 obliquely penetrate the outer wall of the power drum 52, and the first limiting groove 521 and the second limiting groove 522 are arranged in an "X" shape. Both ends of the power rod 56 can slide within the first limiting groove 521 or the second limiting groove 522. At the same time, the power rod 56 drives the power drum 52 to rotate. The elliptical cylindrical structure of the power rod 56 can ensure that the power rod 56 will not change track at the intersection of the first limiting groove 521 and the second limiting groove 522.

[0061] To prevent the power drum 52 from rotating under the action of other external forces, such as Figure 12As shown, a protruding plate 523 can also be fixed to both sides of the power rotating drum 52. Each protruding plate 523 has two limiting ports 5231, which are located at the beginning and end of the first limiting groove 521 and the second limiting groove 522. The limiting ports 5231 connect the inside and outside of the first limiting groove 521 and the second limiting groove 522, allowing the power rod 56 to enter the first limiting groove 521 or the second limiting groove 522 through the limiting ports 5231. At this time, the rotating telescopic structure 5 also includes a limiting wheel 57, which is mounted on the power rotating shaft 55.

[0062] like Figure 13 As shown, in one embodiment of the limiting wheel 57, the limiting wheel 57 includes a connecting plate 571 and an arc-shaped limiting plate 572. The connecting plate 571 has a connecting disc extending outwards from its center. The connecting disc is fixedly or detachably connected to the top of the power shaft 55. The connection method can be any of the existing technologies, as long as it ensures synchronous rotation with the power shaft 55 and that the limiting wheel 57 does not deviate from the power rod 56. Arc-shaped limiting plates 572 are fixedly connected to both ends of the connecting plate 571, and the arc-shaped limiting plates 572 can slide within the limiting opening 5231. In one embodiment, the connecting plate 571 is "Z"-shaped, and the horizontal height of the end of the connecting plate 571 away from the connecting disc is lower than the horizontal height of the end near the connecting disc, so that the arc-shaped limiting plate 572 can smoothly enter the limiting opening 5231. It should be noted that the distance between the arc-shaped limiting plate 572 and the power shaft 55 should be appropriate. That is, it should be ensured that when the power shaft 55 just slides out of the first limiting groove 521 or the second limiting groove 522, the arc-shaped limiting plate 572 just slides into the limiting opening 5231. Furthermore, the length of the connecting plate 571 is less than the length of the power rod 56, so that the arc-shaped limiting plate 572 cannot enter the first limiting groove 521 or the second limiting groove 522. Thus, the arc-shaped limiting plate 572 only serves to restrict the rotation of the power drum 52, and does not drive the power drum 52 to rotate.

[0063] The end of the power shaft 55 away from the limit wheel 57 is also provided with a power device (not shown in the figure). The power device can be any of the existing technologies, as long as it can provide rotational power to the power shaft 55. It will not be described in detail here.

[0064] by Figure 12For example, when in use, the power device is turned on, and the power shaft 55 rotates clockwise. The power shaft 55 drives the power rod 56 and the limiting wheel 57 to rotate clockwise synchronously. The power rod 56 slides in the second limiting groove 522 and drives the power drum 52 to rotate in the forward direction (that is, the first limiting groove 521 rotates downward). The power drum 52 drives the rotating rod 512 and the water pipe connecting arm 511 to rotate, thereby driving the spray rod 4 and the nozzle 6 to rotate in the forward direction. When the power rod 56 slides to the end of the second limiting groove 522, the arc-shaped limiting plate 572 just slides into the limiting opening 5231 at the beginning of the first limiting groove 521. The power rod 56 continues to rotate, and the arc-shaped limiting plate 572 slides in the limiting opening 5231. At this time, the power drum 52 does not rotate. After the power shaft 55 rotates 180 degrees, the other end of the power rod 56 slides into the first limiting groove 521, and drives the power drum 52 to rotate in the opposite direction (that is, the first limiting groove 521 rotates upward), thereby driving the water spray rod 4 and the nozzle 6 to rotate in the opposite direction. This subsequent cyclical motion is not described in detail.

[0065] The power shaft 55 also drives the cam 54 to rotate clockwise. The groove 541 rotates with the cam 54. The groove 541 has an irregular shape, so it can drive the second short rod 532 to rotate around the connecting shaft 533 as the rotation point, and then drive the first short rod 531 to rotate. This enables the first short rod 531 to drive the rotating rod 512 to perform periodic telescopic movements in the power drum 52, and further drive the water spray bar 4 and the nozzle 6 to perform periodic telescopic movements, so that the nozzle 6 sprays more evenly at the feed inlet of the wood chipper.

[0066] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
