Description

Technical Field

[0001] The utility model relates to the field of wood bark residues, in particular to a cleaning and recycling device for recycling wood bark residues. Background Art

[0002] In the process of tree processing, some of the bark of the tree will be bumped and peeled off from the wood, which is usually regarded as waste. However, the bark of the wood still has certain value and potential use. Cleaning and recycling the remaining bark of the wood can reuse it as a resource to avoid waste. At the same time, if the remaining bark of the wood is discarded at will, it will increase the amount of garbage and burden the garbage disposal system. Cleaning and recycling the remaining bark of the wood can reduce the total amount of garbage and reduce the pressure on garbage disposal facilities.

[0003] The existing wood bark waste recycling process still requires manual cleaning and recycling of bark and other waste materials. In the form of an automated assembly line, workers may cause the bark waste to fall to the ground or under the vehicle during the automatic cleaning and recycling of waste materials on the transport truck pallet, resulting in the need for secondary cleaning later. This results in low operating efficiency, high labor intensity and high labor costs. Utility Model Content

[0004] In view of this, the purpose of the utility model is to propose a cleaning and recovery device for recovering wood bark residues, so as to solve the technical problems that the existing wood bark residue recovery operation process still requires manual cleaning and recovery of bark and other residues, resulting in the subsequent residues dropped on the ground needing to be cleaned up again, resulting in low operation efficiency, high manual labor intensity and high labor costs.

[0005] Based on the above purpose, the utility model provides a cleaning and recycling device for recycling wood bark residues, which is used to clean up the bark residues accumulated on the surface of a pallet, including a recovery box for collecting the cleaned residues and a cleaning box for blowing off the residues on the surface of the pallet, and a conveying component for conveying the collected residues;

[0006] The recycling box comprises two groups of baffles perpendicular to the ground, a collecting plate is arranged inside the baffle, a slope is arranged at the front end of the collecting plate, and a cleaning component for cleaning the bark residue is fixed inside the baffle;

[0007] The cleaning box includes a mounting plate arranged on the top surface of the baffle, two groups of fans are fixed on the surface of the mounting plate, a three-way pipe is connected between the two groups of fans, an air guide pipe is also connected to the top of the three-way pipe, and an air outlet pipe is fixed at the output end of the air guide pipe.

[0008] Preferably, two groups of coarse filter screens connected to the interior of the recovery box are provided inside the mounting plate, two groups of vertical plates and a dust collector are also fixed on the surface of the mounting plate, and a fine filter screen is fixed between the two groups of vertical plates.

[0009] Preferably, the dust collector includes dust suction ports arranged on both sides thereof and a dust collecting box located between the two groups of dust suction ports.

[0010] Preferably, the conveying assembly includes a conveyor belt and a second motor fixed on the outside of the baffle, and three groups of rotating rollers are arranged inside the conveyor belt, one group of rotating rollers is rotatably arranged on the inner wall of the baffle and connected to the output end of the second motor, and the other two groups of rotating rollers are fixed with brackets at the ends.

[0011] Preferably, the cleaning assembly includes a scraper located above the collecting plate, a fixing frame fixed to the inner wall of the baffle is provided on one side of the scraper, a first motor is fixedly provided at one end of the fixing frame, a pull rope is connected above the scraper, two sets of pulleys are fitted on the outside of the pull rope, one end of the pull rope is connected to an opening and closing door, a shield plate is also fixed between the two sets of baffles, and the opening and closing door is fitted with the shield plate.

[0014] Preferably, a limiting slide bar is fixedly provided on one side of the opening and closing door, and a slideway for the limiting slide bar to slide is provided on one side of the shield.

[0015] Beneficial effects of the utility model:

[0016] The utility model starts the fan fixed on the surface of the mounting plate inside the cleaning box, so that the airflow intersects inside the three-way pipe, moves along the air guide pipe to the air outlet pipe and then blows out, and blows the residual material into the recovery box. Due to the conical structure of the air outlet pipe, another part of the airflow is blown to the bottom surface of the tray and the ground, so that part of the residual material accidentally dropped on the bottom surface is continued to be blown by the airflow passing through the bottom surface of the tray and the ground, and moves along the inclined surface to the surface of the collecting plate. As the bark residual material accumulates on the collecting plate, the bark residual material can be sent to the conveying component through the cleaning component, and is sent to the next processing step by the conveying component, which solves the problem that the existing wood bark residual material recycling operation process still needs to be manually cleaned and recycled for bark and other residual materials, resulting in the subsequent residual material dropped on the ground needing to be cleaned twice, the operation efficiency is low and the manual labor intensity is high.

[0027] In order to further understand the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Combination Figure 1-Figure 3 The utility model provides a cleaning and recycling device for recycling wood bark residues, which is used to clean the bark residues accumulated on the surface of a pallet 1, including a recovery box 2 for collecting the cleaned residues and a cleaning box 3 for blowing off the residues on the surface of the pallet 1, and a conveying component 4 for conveying the collected residues;

[0029] The recycling box 2 includes two sets of baffles 21 perpendicular to the ground, a collecting plate 211 is arranged inside the baffle 21, a slope 212 is arranged at the front end of the collecting plate 211, and a cleaning component 22 for cleaning the bark residue is fixed inside the baffle 21;

[0030] The cleaning box 3 includes a mounting plate 31 disposed on the top surface of the baffle 21, two sets of fans 32 are fixed on the surface of the mounting plate 31, a three-way pipe 33 is connected between the two sets of fans 32, the top of the three-way pipe 33 is also connected to an air guide pipe 34, and an air outlet pipe 341 is fixed to the output end of the air guide pipe 34;

[0031] In this embodiment, the pallet 1 is first transported to one side of the recycling box by the movement of the truck, and then the fan 32 fixed on the surface of the mounting plate 31 inside the cleaning box 3 is started. As the fan 32 is started, the airflow intersects inside the three-way pipe 33, moves along the air guide pipe 34 to the air outlet pipe 341, and then blows out. The central axis of the air outlet pipe 341 is located at the center of the height of the pallet 1, so that the airflow blown out from the output port of the air outlet pipe 341 will be divided by the pallet 1, and a part of the airflow will clean the bark residue accumulated on the surface of the pallet 1 and blow the residue into the recycling box 2, and the other part of the airflow will be blown to the bottom surface of the pallet 1 and the ground, so that part of the residue that accidentally falls to the bottom surface of the pallet 1 during the process of blowing away the bark residue above the pallet 1 will continue to be blown by the airflow passing through the bottom surface of the pallet 1 and the ground;

[0032] Furthermore, since a slope 212 is provided at one end of the collecting plate 211, the bark residue at the bottom surface will be pushed by the airflow and move along the slope 212 to the surface of the collecting plate 211. As the bark residue accumulates on the collecting plate 211, the cleaning component 22 can send the bark residue to the conveying component 4, and the conveying component 4 will send it to the next processing step, such as crushing or incineration.

[0033] Combination Figure 2 The mounting plate 31 is provided with two groups of coarse filter screens 311 connected to the inside of the recovery box 2. Two groups of vertical plates 35 and a dust collector 36 are also fixed on the surface of the mounting plate 31. A fine filter screen 351 is fixed between the two groups of vertical plates 35.

[0034] In this embodiment, when the fan 32 is started, in order to ensure the normal output of the fan 32, one side of the fan 32 will continue to absorb airflow, and the coarse filter 311 provided on the surface of the mounting plate 31 can effectively maintain the exchange of air between the fan 32 and the outside air, and at the same time ensure that the large pieces of residual material blown into the recovery box 2 will not enter the cleaning box 3;

[0035] Furthermore, the vertical plates 35 arranged on the surface of the mounting plate 31 separate the space in the cleaning box 3 , and the fine filter screen 351 between the two groups of vertical plates 35 further ensures that fine residual materials will not enter the fan 32 .

[0036] Combination Figure 4 , the dust collector 36 includes dust suction ports 361 arranged on both sides thereof and a dust collection box 362 located between the two groups of dust suction ports 361;

[0037] In this embodiment, the dust collector 36 is used to absorb the dust generated by the bark residue during the blowing and cleaning process. The dust enters from the dust suction port 361 and then enters the dust collecting box 362. The dust collecting box 362 is provided with an electrostatic device inside to firmly absorb the dust. The working principle of the dust collector 36 is the existing technology and will not be elaborated here.

[0038] Combination Figure 2 The conveying assembly 4 includes a conveyor belt 41 and a second motor 44 fixed on the outside of the baffle 21. Three groups of rotating rollers 42 are arranged inside the conveyor belt 41, one group of rotating rollers 42 is rotatably arranged on the inner wall of the baffle 21 and connected to the output end of the second motor 44, and the ends of the other two groups of rotating rollers 42 are fixedly provided with brackets 43;

[0039] In this embodiment, when the bark residue is sent to the conveying component 4 by the cleaning component 2, the second motor 44 is started to drive the rotating roller 42 located on the inner wall of the baffle 21, so that the conveyor belt 41 operates to convey the bark residue. The other two groups of rotating rollers 42 are used to change the operating direction and stability of the conveyor belt 41, and the bracket 43 arranged at its end is used to support the conveyor belt 41.

[0040] Combination Figure 3 The cleaning assembly 22 includes a scraper 221 located above the collecting plate 211, a fixing frame 222 fixed to the inner wall of the baffle 21 is provided on one side of the scraper 221, a first motor 223 is fixedly provided at one end of the fixing frame 222, a pull rope 224 is connected to the top of the scraper 221, two groups of pulleys 225 are fitted on the outer side of the pull rope 224, an opening and closing door 226 is connected to one end of the pull rope 224, a shielding plate 213 is also fixed between the two groups of baffles 21, and the opening and closing door 226 is fitted with the shielding plate 213;

[0041] In this embodiment, the scraper 221 is used to scrape off the bark residue accumulated on the collecting plate 211. The scraper 221 can slide linearly along its length direction on the fixing frame 222. After the first motor 223 at one end of the fixing frame 222 is started, it is used to provide the scraper 221 with the power required for transportation.

[0042] Furthermore, when the scraper 221 moves, it can drive the pull rope 224 to move in the opposite direction. The moving pull rope 224 is guided and assisted by the pulley 225 to avoid path deviation during the movement. When the pull rope 224 is pulled, it can drive the opening and closing door 226 to rise, so that the scraper 221 can push the bark residue out of the recycling box 2. The opening and closing door 226 fits with the baffle 213 to make one side of the recycling box 2 play a blocking role, which is convenient for better collection of the bark residue.

[0043] Combination Figure 5 Two sets of guide rods 2221 are fixedly arranged inside the fixing frame 222, a lead screw 2231 is fixedly arranged at the output end of the first motor 223, a slider 227 is arranged on the lead screw 2231, a second rotating shaft 2271 and a third rotating shaft 2272 are arranged on one side of the slider 227, a connecting strip 2211 connected to the second rotating shaft 2271 is fixedly arranged on the upper end of the scraper 221, and a baffle 2273 located on one side of the connecting strip 2211 is also fixedly arranged on one side of the slider 227;

[0044] In this embodiment, the first motor 223 is started to drive the lead screw 2231 to rotate, and the rotating lead screw 2231 drives the slider 227 to move linearly along its axis. During the movement of the slider 227, the guide rod 2221 fixed to the fixing frame 222 can guide and stabilize the slider 227 to prevent the slider 227 from shaking.

[0045] Furthermore, the connection strip 2211 at the upper end of the scraper 221 is connected to the second shaft 2271 on one side of the slider 227 to prevent the scraper 221 from blocking the bark residue from entering the recovery box 2 when the air outlet pipe 341 blows out air to remove the bark residue. The second shaft 2271 is set so that when the air outlet pipe 341 blows out air, the scraper 221 will be blown and parallel to the air flow direction. The scraper 221 is made of lightweight composite plastic to ensure its own light weight while also ensuring its own strength. The baffle 2273 on one side of the slider 227 can ensure that the scraper 221 will not rotate when scraping and transporting the bark residue on the surface of the collecting plate 211. When there are too many bark residues accumulated on the surface of the collecting plate 211, the second shaft 2271 can also ensure that the scraper 221 will not push the residue out of the recovery box 2 when performing reciprocating operations.

[0046] Combination Figure 5 The pull rope 224 includes an elastic rope segment 2241 connected to the third rotating shaft 2272 and a rigid rope segment 2242 in contact with the pulley 225. The pulley 225 is provided with a first rotating shaft 2251 rotating on the inner wall of the baffle 21;

[0047] In this embodiment, the third rotating shaft 2272 can ensure that the pull rope 224 changes the traction direction at all times as the scraper 221 moves. The elastic rope segment 2241 on the pull rope 224 is set to eliminate the difference in displacement distance, thereby preventing the slider 227 from moving too long and causing the opening and closing door 226 to rise too far and cause damage. The setting of the rigid rope segment 2242 can better pull the opening and closing door 226 upward.

[0048] Combination Figure 5 The opening and closing door 226 has a fixed limit slide bar 2261 on one side, and the shield 213 has a slideway for the limit slide bar 2261 to slide.

[0049] In this embodiment, the setting of the limiting slide bar 2261 can ensure that the position of the opening and closing door 226 will not be offset during the rising process, while ensuring the connectivity between the opening and closing door 226 and the shielding plate 213.
