Description

Technical Field

[0001] The invention relates to the technical field of crushing equipment, in particular to a forestry residue crushing and mixing integrated machine. Background Art

[0002] Forestry residues include waste generated during the logging and timber making process, such as bark, leaves, grass clippings, vines and other plant residues. These forestry residues remain on the surface, providing habitats and food sources for pests and diseases, leading to the breeding and spread of pests and diseases. Due to their own shape limitations, they cannot fully connect with the soil, resulting in low decomposition efficiency, delayed fertility release, and failure to meet plant needs in a timely manner; The existing application number is CN202410888294.X, which is a crushing device for discarded branches after pruning. The patent document discloses a method of using a reversible bucket to collect branches and fallen leaves on the ground and crush them step by step. Specifically, a first crushing mechanism is installed above the base on one side of the bucket, and the bucket rotates and puts the discarded branches inside into the first crushing mechanism; the discarded branches and fallen leaves on the ground are crushed once, so that the base can automatically crush the discarded branches and fallen leaves on the ground during the movement, and then the fallen leaves and branches after the first crushing are transported to the second crushing mechanism for fine crushing. Screens with different mesh diameters are replaced according to different uses of the crushed materials, so that the second crushing mechanism can handle crushed materials of different specifications; However, when using the technical solution in the above patent document, the surface of the forestry planting site cannot be as flat as a highway road, the bucket cannot adapt to the rugged forestry planting terrain, the shoveling efficiency is low, and foreign objects such as stones in the shoveled branches or leaves cannot be distinguished and removed. Affected by these foreign objects, the service life of the crushing blade is greatly reduced; in addition, although the crushing method helps to improve the composting efficiency of the leaves, there is no container for collecting the crushed leaves in the device. The direct discharge of the debris to the ground will cause pathogens and fungal spores to remain in the leaves, leading to the breeding and spread of pests and diseases, and the debris flying in the wind will increase the burden of pests on forestry management. Therefore, the present application provides a forestry residue crushing and mixing all-in-one machine. Summary of the invention

[0003] In order to address the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide an all-in-one forestry residue crushing and mixing machine, which is designed for forestry planting terrain with relatively rugged surfaces.

[0007] Furthermore, multiple secondary crushing rollers are divided into multiple groups in pairs, and a material guide edge is installed between two adjacent groups of secondary crushing rollers; among the two secondary crushing rollers in the same group, a gear shaft is provided at the end of one of the secondary crushing rollers, and an outer gear ring II is provided at the end of the other secondary crushing roller, and the gear shaft and the outer gear ring II are connected through meshing transmission; a cover plate is detachably fixedly installed on the frame, and the gear shaft penetrates the cover plate and extends toward the outside of the cover plate; a motor I for driving the gear shaft to rotate is installed on the cover plate.

[0008] Furthermore, an outer gear ring I is fixedly installed on the end of the cylindrical end cover, a motor II is fixedly installed on the top of the collection seat, a driving gear is installed on the output shaft of the motor II, and the driving gear is connected to the outer gear ring I through a transmission belt.

[0009] Furthermore, an anti-emission baffle is integrally formed inside the introduction cavity, and a scraping brush is detachably fixedly installed on the outer side of the anti-emission baffle, and the scraping brush extends toward the gap between the multiple primary crushing hooks.

[0010] Furthermore, a material box is fixedly installed on the top of the crushing chamber, and an introduction pipe is fixedly and connected to the bottom of the material box, and the introduction pipe extends downward into the crushing chamber.

[0011] Furthermore, the interior of the material guide edge is hollow, the top edge of the material guide edge is connected to the introduction pipe, and a plurality of feeding ports are arranged at equal intervals at the bottom of the material guide edge.

[0012] Furthermore, the storage box is slidably installed in the frame, and a side panel is fixedly installed on the side of the frame. The inner wall of the side panel abuts against the outer side of the storage box. A plurality of strip protrusions are arranged at the bottom of the storage box, and a plurality of slide grooves corresponding to the strip protrusions are arranged on the upper side of the bottom of the frame. The strip protrusions are slidably connected with the slide grooves.

[0013] In the present application, an optional technical solution for the connection between the collection seat and the L-shaped seat is: the collection seat is fixedly installed on the lower side of the L-shaped seat, and the L-shaped seat is provided with insertion grooves for placing multiple catheters.

[0014] In the present application, another optional technical solution for the connection method between the collection seat and the L-shaped seat is: the collection seat is movably installed on the lower side of the L-shaped seat, and a plurality of limit columns are fixedly installed on the top of the collection seat, the limit columns pass through the circular holes on the L-shaped seat, the diameter of the limit columns is smaller than the diameter of the circular holes, and a spherical end head is provided on the top of the limit column, and the diameter of the spherical end head is larger than the diameter of the circular hole; a tension spring is installed on the outer side of the limit column, and the two ends of the tension spring are respectively fixedly connected to the L-shaped seat and the collection seat.

[0015] Among them, support wheels are respectively arranged at the front and rear ends of the bottom of the introduction cavity, and the support wheel located at the front side of the fixing ring is connected to the fixing ring through two arc-shaped iron sheets.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the forestry residue crushing and mixing machine of the example of the present invention, at least two return springs are fixedly installed between the placement grooves on two adjacent core shafts. These return springs are arranged horizontally at intervals, so that the two core shafts can only be slightly displaced in the vertical or horizontal direction, limiting the core shaft to rotate about its own axis, so that the primary crushing hooks corresponding to the bottom of the adjacent core shafts can act on forestry residues accumulated at different surface heights, so that the equipment can adapt to the relatively rugged forestry planting terrain.

[0017] 2. The forestry residue crushing and mixing integrated machine of the example of the present invention controls the rotation of the driving gear. Under the action of the transmission belt, the outer gear ring I, the cylindrical end cover and the collecting barrel on the collecting unit at the end are driven to rotate synchronously. Under the pulling action of multiple steel wire ropes, the collecting barrels on multiple collecting units in the middle are driven to rotate synchronously. The primary crushing hook on the side of the collecting barrel is used to scrape the messy branches on the surface to increase the degree of branch crushing. At the same time, the branches and fine leaves on the ground are selectively collected. Based on the limitation of the width of the primary crushing hook and the weight of the stone, the crushed stone is prevented from entering the machine body, ensuring the long-term and stable operation of the crushing tool.

[0018] 3. In the forestry residue crushing and mixing machine of the example of the present invention, the length of the wire rope is longer than the distance between the inner walls of two adjacent cylindrical end covers, so that after the two core shafts are slightly displaced in the vertical or horizontal direction, the wire rope drives the adjacent cylindrical end covers to rotate through slight deformation, thereby realizing synchronous control of the collecting cylinders in multiple collecting units; the collecting cylinders on multiple collecting units are well controlled synchronously, reducing the number of driving devices used.

[0019] 4. In the forestry residue crushing and mixing machine of the example of the present invention, the air compressor is started, so that the compressed air flows through the air pipe and the air inlet into the introduction chamber, blows up the branches and fine leaves at the bottom of the introduction chamber, and is intercepted by the anti-emission baffle and the scraping brush. The blown forestry residue is guided to the exhaust port, and then flows through the conduit and the crushing feed port in turn, and enters the crushing chamber. The compressed air is discharged to the outside of the equipment through the filter holes on the double-layer filter plate, and the branches and fine leaves are intercepted by the filter holes and retained in the crushing chamber, thereby completing the separation between air and forestry residue.

[0020] 5. The forestry residue crushing and mixing integrated machine of the example of the present invention controls the rotation of multiple secondary crushing rollers. Two secondary crushing rollers in the same group rotate synchronously in opposite directions. Multiple material guides guide the forestry residues to the middle of the multiple groups of secondary crushing rollers. Under the joint action of the multiple groups of secondary crushing rollers, leaves and fine leaves are crushed and thrown into the storage box for storage. Since the secondary crushing rollers are slender in structure and have a large space on the upper side, forestry residues of different dryness and wetness are retained on the upper side of the secondary crushing rollers at the same time. During the rotation of the multiple groups of secondary crushing rollers, forestry residues of different dryness and wetness in the crushing chamber are crushed and mixed, avoiding the accumulation of forestry residues with higher humidity in local positions in the storage box, thereby ensuring the subsequent composting efficiency of the forestry residues in the storage box.

[0029] Embodiment 1: like Figure 1 , Figure 2 and Figure 3 As shown, the present embodiment provides a forestry residue crushing and mixing machine, comprising a frame 11, a storage box 1 is arranged in the frame 11, a wheel 111 is rotatably installed at the bottom of the frame 11, a crushing chamber 14 is fixedly and connected to the top of the frame 11, a plurality of secondary crushing rollers 51 are rotatably installed in the crushing chamber 14, the plurality of secondary crushing rollers 51 are divided into a plurality of groups in pairs, a material guide edge 52 is installed between two adjacent groups of secondary crushing rollers 51, the storage box 1 is located at the lower side of the crushing chamber 14, a crushing feed port 15 and a double-layer filter plate 16 are respectively arranged at the front and rear ends of the crushing chamber 14; the front end of the frame 11 is connected to a collection seat 22 through an L-shaped seat 21, and embedded arms 23 are respectively arranged on both sides of the bottom of the collection seat 22, a cylindrical end cover 31 is rotatably installed on the outer side of the embedded arm 23, and a plurality of collecting units are arranged between the two embedded arms 23.

[0030] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the collecting unit includes a core shaft 24, a collecting tube 34 is rotatably mounted on the outer side of the core shaft 24, an introduction chamber 41 is arranged on the rear side of the collecting tube 34, and a fixing ring 411 on the introduction chamber 41 is sleeved and rotatably connected with the edge of the collecting tube 34; placement grooves 241 are respectively arranged at both ends of the core shaft 24, the placement grooves 241 on the core shaft 24 located at the edge are plugged and fixedly connected with the embedded arm 23, and at least two return springs 242 are fixedly mounted between the placement grooves 241 on adjacent core shafts 24; a plurality of partitions 341 are arranged at equal angular intervals on the inner side of the end of the collecting tube 34, the collecting tube 34 located at the edge is fixedly connected with the cylindrical end cover 31, and a plurality of steel wire ropes 36 are arranged between adjacent cylindrical end covers 31, and the number of steel wire ropes 36 corresponds to the number of partitions 341; a plurality of primary crushing and picking hooks 35 are fixedly mounted on the outer side of the collecting tube 34.

[0031] like Figure 5 and Figure 6 As shown, since at least two return springs 242 are fixedly installed between the placement grooves 241 on two adjacent core shafts 24, these return springs 242 are arranged horizontally at intervals, so that the two core shafts 24 can only be slightly displaced in the vertical or horizontal direction, limiting the core shaft 24 to rotate around its own axis, so that the primary crushing hooks 35 corresponding to the bottom of the adjacent core shafts 24 can act on forestry residues accumulated at different surface heights, so that the equipment can be used in forestry planting terrain with relatively rugged surface.

[0032] like Figure 2 , Figure 8 and Fig. 9 As shown, support wheels 42 are respectively provided at the front and rear ends of the bottom of the introduction cavity 41; the two support wheels 42 are used to limit the distance between the primary crushing hook 35 located at the bottom of the equipment and the ground surface, so as to prevent the primary crushing hook 35 from being over-pressed and causing the soil to turn over; the support wheel 42 located at the front side of the fixing ring 411 is connected to the fixing ring 411 through two arc-shaped iron sheets 421, and the elastic deformation of the arc-shaped iron sheet 421 is used to realize the adaptive adjustment of the support wheel 42 at the front end to the rugged terrain.

[0033] like Figure 1 , Figure 2 and Figure 8 As shown, the upper and lower sides of the introduction cavity 41 are respectively connected with an exhaust port 44 and an air inlet 43, and a plurality of foreign matter interception ridges 46 are fixedly installed on the upper side of the bottom of the introduction cavity 41 to block animal hair. The exhaust port 44 is connected with the crushing feed port 15 through a conduit 45, and an insertion groove 211 for placing a plurality of conduits 45 is provided on the L-shaped seat 21. An air compressor 12 is provided at the bottom of the frame 11, and the air compressor 12 is connected to the air inlet 43 through an air pipe; wherein the air compressor 12 uses a small screw air compressor on the market.

[0034] like Figure 3and Figure 4 As shown, an outer gear ring I is fixedly installed on the end of the cylindrical end cover 31, a motor II 32 is fixedly installed on the top of the collection seat 22, a driving gear is installed on the output shaft of the motor II 32, and the driving gear is connected to the outer gear ring I through a transmission belt 33.

[0035] The specific details of the forestry residue crushing and mixing machine using this application are as follows: 1. Preparation before use: Manually lift the collecting unit and check the deformation capacity of the return spring 242 between the multiple collecting units to ensure that the two adjacent collecting units can be slightly displaced from each other to adapt to the use of rugged forestry planting terrain; use an endoscope to check whether there are foreign objects in the introduction cavity 41 and the crushing cavity 14 to avoid obstruction of the operation of the secondary crushing roller 51.

[0036] 2. Collecting forestry residues into the inlet cavity 41: Start motor II 32 to control the rotation of the driving gear. Under the action of the transmission belt 33, the outer gear ring I, the cylindrical end cover 31 and the collection barrel 34 on the collection unit at the end are driven to rotate synchronously. Under the pulling action of multiple steel wire ropes 36, the collection barrels 34 on multiple collection units in the middle are driven to rotate synchronously. The primary crushing hook 35 on the side of the collection barrel 34 is used to scrape the messy branches on the surface to increase the degree of branch crushing. At the same time, the branches and fine leaves on the ground are selectively collected. Based on the width limitation of the primary crushing hook 35 and the weight of the stone, the crushed stone is prevented from entering the machine body to ensure the long-term and stable operation of the crushing tool.

[0037] 3. Introducing forestry residues into the crushing chamber 14: Start the air compressor 12, so that the compressed air flows through the air pipe and the air inlet 43 into the introduction chamber 41, blows up the branches and fine leaves at the bottom of the introduction chamber 41, and is intercepted by the anti-escape baffle 47 and the scraping brush 48. The blown forestry residues are guided to the exhaust port 44, and then flow through the duct 45 and the crushing feed port 15 in turn, and enter the crushing chamber 14. The compressed air is discharged to the outside of the equipment through the filter holes on the double-layer filter plate 16, and the branches and fine leaves are intercepted by the filter holes and remain in the crushing chamber 14, completing the separation between air and forestry residues.

[0038] 4. Crush and mix the forestry residues in the crushing chamber 14: The rotation of multiple secondary crushing rollers 51 is controlled, and the two secondary crushing rollers 51 in the same group rotate synchronously in opposite directions. Multiple material guides 52 guide the forestry residues to the middle of the multiple groups of secondary crushing rollers 51. Under the joint action of the multiple groups of secondary crushing rollers 51, the leaves and finely divided leaves are crushed and thrown into the storage box 1 for storage. Since the secondary crushing rollers 51 are slender in structure and the upper space is large, the forestry residues of different dryness and wetness are retained on the upper side of the secondary crushing rollers 51 at the same time. During the rotation of the multiple groups of secondary crushing rollers 51, the forestry residues of different dryness and wetness in the crushing chamber 14 are crushed and mixed, so as to avoid the accumulation of forestry residues with higher humidity in local positions in the storage box 1, thereby ensuring the efficiency of subsequent composting of the forestry residues in the storage box 1.

[0039] In the above step 2, the length of the steel wire rope 36 is longer than the distance between the inner walls of two adjacent cylindrical end covers 31, so that after the two core shafts 24 are slightly displaced in the vertical or horizontal direction, the steel wire rope 36 drives the adjacent cylindrical end covers 31 to rotate through slight deformation, thereby realizing synchronous control of the collection cylinders 34 in multiple collection units; the collection cylinders 34 on multiple collection units are well synchronously controlled, reducing the number of driving devices used.

[0040] In the above step three, by adjusting the real-time power of the air compressor 12 and the rotation speed of the collection tube 34, the airflow intensity of the compressed air entering the air inlet 43 changes periodically. When the compressed air airflow intensity is weak, part of the forestry residues in the inlet cavity 41 are affected by gravity and discharged from the bottom front side of the inlet cavity 41 again, further avoiding gravel from entering the interior of the machine body and ensuring the stability of continuous use of the equipment.

[0041] Using the above scheme of the present application, leaves of different dryness and wetness collected from the ground are crushed and mixed, and the products are collected. By controlling the subsequent dryness and wetness, composting treatment is carried out to inactivate the pathogens and fungal spores remaining on the branches and leaves, thereby building a biosafety guarantee system for subsequent crop growth.

[0042] In the present application, for the mobile traction mode of the frame 11, an optional technical solution is: motors for driving the wheels 111 to rotate are respectively provided at the four corners of the bottom of the frame 11; another optional technical solution is: a power traction device is provided at the front end of the frame 11, such as a small agricultural tractor or a crawler trailer, and the power traction device is provided at the front end of the collection seat 22 and connected to the frame 11.

[0043] In order to increase the smoothness of the equipment to import leaves, such as Figure 8 and Fig. 9As shown, an anti-emission baffle 47 is integrally formed inside the inlet chamber 41. When a large amount of leaves instantaneously flow through the inlet chamber 41, the anti-emission baffle 47 is used to guide these leaves to prevent the leaves from leaking out from the upper end of the side of the inlet chamber 41. A scraping brush 48 is detachably fixedly installed on the outer side of the anti-emission baffle 47. The scraping brush 48 extends toward the gap between the multiple primary crushing hooks 35 to remove grass clippings and fine leaves from the primary crushing hooks 35, thereby ensuring the subsequent collection efficiency of the leaves by the primary crushing hooks 35.

[0044] In this embodiment, the rotation control method for the secondary crushing roller 51 is as follows: a motor III is fixedly installed on the side of the frame 11, the number of motor III is consistent with the secondary crushing roller 51, and the output shaft of motor III is connected to the rotating shaft of the secondary crushing roller 51 through a coupling.

[0045] In this embodiment, the collection seat 22 and the L-shaped seat 21 are connected in the following manner: the collection seat 22 is fixedly installed on the lower side of the L-shaped seat 21, and the L-shaped seat 21 is provided with an insertion groove 211 for placing multiple catheters 45.

[0046] Embodiment 2: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 and Figure 3 As shown, the collection seat 22 is movably mounted on the lower side of the L-shaped seat 21, and the specific method is as follows: A plurality of limiting columns 221 are fixedly installed on the top of the collection seat 22. The limiting columns 221 pass through the circular holes on the L-shaped seat 21. The diameter of the limiting columns 221 is smaller than the diameter of the circular holes. A spherical end is provided on the top of the limiting columns 221. The diameter of the spherical end is larger than the diameter of the circular holes. A tension spring 222 is sleeved on the outer side of the limiting columns 221. The two ends of the tension spring 222 are fixedly connected to the L-shaped seat 21 and the collection seat 22 respectively.

[0047] like Figure 3 As shown, the limit column 221 and the circular hole are designed with clearance fit, and the difference in diameter between the two allows the limit column 221 to achieve axial sliding and slight deflection movement in the circular hole; the top surface of the collection seat 22 can form a dynamic inclination according to the undulations of the terrain, which significantly improves the adaptability of the equipment in complex forestry terrain. The tension spring 222 continuously provides a restoring torque. When the ground returns to flatness, the top surface of the traction collection seat 22 is automatically reset to a horizontal reference state. The spherical end of the limit column 221 is an anti-slip structure, which restrains the axial movement of the limit column 221 and prevents the components from detaching from each other, thereby ensuring the reliability of the mechanism operation.

[0048] Embodiment three: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Fig.12 As shown, in this embodiment, two of the secondary crushing rollers 51 in the same group, one of the secondary crushing rollers 51 is provided with a gear shaft 511 at the end, and the other secondary crushing roller 51 is provided with an outer gear ring II 512 at the end, and the gear shaft 511 and the outer gear ring II 512 are connected by meshing transmission; a cover plate 113 is detachably fixedly mounted on the frame 11, and the gear shaft 511 penetrates the cover plate 113 and extends toward the outer side of the cover plate 113; a motor I for driving the gear shaft 511 to rotate is installed on the cover plate 113.

[0049] Start the motor I to drive the gear shaft 511 to rotate, and utilize the meshing transmission between the gear shaft 511 and the outer gear ring II 512 to make the two secondary crushing rollers 51 in the same group rotate synchronously in opposite directions to crush and mix the leaves of different dryness and wetness entering the crushing chamber 14.

[0050] Compared with the embodiment 1, in which multiple secondary crushing rollers 51 are driven to rotate by independent control, the above scheme of this embodiment is used, and the two secondary crushing rollers 51 in the same group rotate synchronously. Fig.12 As shown, the two side crushing teeth of the secondary crushing roller 51 extend in a spiral trajectory. The spiral trajectories of the crushing teeth on the two secondary crushing rollers 51 are in opposite directions to each other, forming a material directional conveying mechanism during the crushing process. The material that cannot be crushed immediately will be continuously pushed along the spiral trajectory toward the rear end of the crushing chamber 14, greatly reducing the risk of material jamming and increasing the continuous operation effect of the equipment.

[0051] Embodiment 4: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Fig.11 , Fig.12 and Fig.13 As shown, in this embodiment, a material box 53 is fixedly installed on the top of the crushing chamber 14, and an introduction pipe 54 is fixedly and connected to the bottom of the material box 53, and the introduction pipe 54 extends downward into the crushing chamber 14; When the material box 53 is only filled with the composite bacterial agent; like Fig.13 As shown, the guide edge 52 is a hollow structure, the top edge of the guide edge 52 is connected to the introduction pipe 54, and a plurality of feeding ports are arranged at equal intervals at the bottom of the guide edge 52; during the driving process of the frame 11, a vibration force is applied to the material box 53, so that the composite bacterial agent in the material box 53 passes through the introduction pipe 54 and the guide edge 52 in turn, and is finally discharged into the storage box 1 through the feeding port to be mixed with the leaf fragments that fall naturally after being crushed.

[0052] When the material box 53 is filled with compound bacterial agent, soil particles, sawdust and manure particles; The guide edge 52 is a solid structure. During the travel of the vehicle frame 11, a vibration force is applied to the material box 53. The composite bacterial agent, soil particles, wood chips and nitrogen, phosphorus and potassium fertilizer particles in the material box 53 are directly placed on the upper side of the multiple guide edges 52. As the airflow transports the leaves into the crushing chamber 14, the wood chips are preliminarily mixed with the leaves and crushed together under the action of multiple secondary crushing rollers 51. In this process, the wood chips can absorb moisture from the relatively moist leaves to prevent the crushed leaf debris from clumping together. The soil particles themselves have a large weight, which increases the bulk density of the mixture, making it easy to pile up and not loose. The manure particles are used to optimize the carbon-nitrogen ratio of the mixture during the composting process, so that the composted mixture can be directly used as fertilizer.

[0053] Embodiment five: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 , Figure 2 and Fig.11 As shown, in this embodiment, the storage box 1 is slidably installed in the frame 11, and the side of the frame 11 is fixedly installed with a side plate 13, the inner wall of the side plate 13 is in contact with the outer side of the storage box 1, and the side of the storage box 1 is fixedly installed with a handle, and the bottom of the storage box 1 is provided with a plurality of strip-shaped protrusions, and the upper side of the bottom of the frame 11 is provided with a plurality of slide grooves 112 corresponding to the strip-shaped protrusions, and the strip-shaped protrusions are slidably connected with the slide grooves 112; The guide function is achieved by engaging the slide groove 112 with the strip protrusion on the bottom of the storage box 1, and the storage box 1 is manually controlled to slide horizontally on the frame 11, so that the storage box 1 can be quickly disassembled and assembled, thereby improving the equipment maintenance efficiency and extending the continuous operation time. In addition, the convenience of disassembly and assembly of the storage box 1 can be further increased by lowering the chassis of the frame 11.
