Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, and in particular to a multifunctional branch and leaf processing machine. Background Technology

[0002] A wood chipper, also known as a mobile wood chipper, garden wood chipper, or mobile shredder, is a new type of mobile, environmentally friendly crushing equipment used to shred waste branches, twigs, scraps, wood, leaves, and other materials.

[0003] To improve operational efficiency, multifunctional leaf and branch processing equipment integrating the functions of leaf crushing, leaf suction, and leaf blowing has emerged. For example, application number CN202941147U discloses a three-in-one suction, crushing, and blowing machine, which has a suction pipe for leaf suction, a coarse material infeed pipe for leaf crushing, and a chip discharge pipe for material discharge or chip blowing on the volute.

[0004] The applicant has discovered that the prior art has at least the following technical problems:

[0005] The aforementioned equipment has only one fixed chip discharge pipe, used for both chip removal and chip blowing. This necessitates disassembling and reconnecting the pipe when switching between chip removal and chip blowing functions. For example, the chip discharge pipe must be removed and replaced with a flexible chip blowing hose to achieve the switching function. Furthermore, the chip discharge pipe is vertically positioned at the top of the volute, resulting in a fixed upward airflow direction. During operation, a long flexible hose is often required to forcibly adjust the airflow direction, leading to high wind resistance, low blowing efficiency, and difficulty in adapting to ground operation requirements, severely limiting the scope and flexibility of the chip blowing operation.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] like Figures 1 to 9As shown, the present invention provides a multifunctional leaf and branch processing machine, including a frame 1, and a crushing component, a leaf suction pipe assembly, a branch shredding pipe assembly, a discharge pipe assembly, a leaf blowing pipe assembly, and a switching component disposed on the frame 1. The leaf suction pipe assembly, branch shredding pipe assembly, discharge pipe assembly, and leaf blowing pipe assembly are all connected to the volute 2 of the crushing component. The switching component is used to ensure that, in the same working mode, only one of the leaf suction pipe assembly and the branch shredding pipe assembly is in a conductive state with the volute 2, and to ensure that the other two components are connected. Only one is in a conductive state with the vortex shell 2; the leaf suction pipe assembly is used to draw fallen leaves into the vortex shell 2 by the negative pressure generated by the rotation of the cutter disc assembly of the crushing component; the branch crushing pipe assembly is used to send the branches to be crushed into the vortex shell 2 for crushing by the cutter disc assembly; the discharge port of the leaf blowing pipe assembly faces the ground and is different from the discharge port of the discharge pipe assembly, so as to discharge the airflow or the airflow carrying the crushed material in the vortex shell 2 towards the ground; the discharge pipe assembly is used to discharge the airflow carrying the crushed material in the vortex shell 2 outward.

[0025] By setting up independent leaf suction pipe components, branch crushing pipe components, discharge pipe components, and leaf blowing pipe components, and coordinating with switching components to adjust their connection status, not only can the working states of leaf suction, leaf blowing, branch crushing, and material discharge be flexibly and quickly switched, but the efficiency and ease of operation of leaf and branch processing are also improved.

[0026] Furthermore, the crushing assembly also includes an engine 3. The cutter head assembly is located inside the crushing chamber of the vortex housing 2 and is connected to the engine 3 via a transmission. The central axis of the vortex housing 2 coincides with the central axis of the cutter head assembly. The engine 3 drives the cutter head assembly to rotate at high speed inside the vortex housing 2. The blades on the cutter head assembly enter the crushing chamber of the vortex housing 2 to cut and crush materials such as branches and leaves. At the same time, the high-speed rotating cutter head assembly continuously agitates the air inside the crushing chamber, forming a negative pressure zone in the central area of ​​the crushing chamber and a high pressure zone at the edge of the crushing chamber. Through the cooperation of the vortex housing 2 and the cutter head assembly, mechanical crushing and pneumatic conveying functions are highly integrated into a single crushing chamber, achieving efficient reuse of power.

[0027] As an optional implementation, such as Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the leaf suction pipeline assembly includes a main leaf suction pipe 4, a first leaf suction branch pipe 5, and a second leaf suction branch pipe 6. The switching assembly includes a first switching element and a second switching element. The inlets of the first leaf suction branch pipe 5 and the second leaf suction branch pipe 6 are respectively connected to the external environment, and the outlets of the first leaf suction branch pipe 5 and the second leaf suction branch pipe 6 are respectively connected to the inlet of the main leaf suction pipe 4. The main leaf suction pipe 4 is connected to the first end face 201 of the volute 2. The central axis of the main leaf suction pipe 4 and the central axis of the first leaf suction branch pipe 5 are both coincident with the central axis of the cutter head assembly. The second leaf suction branch pipe 6 extends towards the ground. The first switching element is movably disposed at the connection between the main leaf suction pipe 4 and the first leaf suction branch pipe 5 and the second leaf suction branch pipe 6, and is used to switch the second leaf suction branch pipe. 6 is in a conductive state with the main suction pipe 4; the second switching element is detachably connected to the inlet of the first suction branch pipe 5, and is used to close or open the inlet of the first suction branch pipe 5; the suction pipe assembly has a first conductive state and a second conductive state. In the first conductive state, the first switching element is located at the connection point and closes the outlet of the second suction branch pipe 6 at the connection point, and the second switching element opens the inlet of the first suction branch pipe 5, so that the external environment, the first suction branch pipe 5, the main suction pipe 4 and the vortex shell 2 are connected in sequence; in the second conductive state, the first switching element is disengaged from the outlet of the second suction branch pipe 6, and the second switching element closes the inlet of the first suction branch pipe 5, so that the external environment, the second suction branch pipe 6, the main suction pipe 4 and the vortex shell 2 are connected in sequence.

[0028] Furthermore, the main suction pipe 4 is located on the first end face 201 of the vortex shell 2 near the blade, and its inner diameter gradually increases in the portion near the vortex shell 2. The discharge port of the main suction pipe 4, with its larger inner diameter, faces the negative pressure zone formed when the cutter head assembly rotates at high speed, which can effectively suck up materials such as blades and improve the suction capacity of the processor. Moreover, after the material is sucked into the crushing chamber, it can come into contact with the high-speed rotating blades, improving the crushing efficiency.

[0029] Existing leaf-collecting and blowing machines only have one suction pipe for fine particles, with its air inlet facing the ground. While this design is suitable for collecting fine fallen leaves, it cannot meet the needs of collecting leaves at higher positions or different angles. Because the suction path is singular and fixed, the equipment has poor mobility and cannot flexibly adapt to complex garden environments. In contrast, the first suction branch pipe 5 of this invention extends horizontally with its inlet facing forward, suitable for collecting leaves in front of the equipment and at higher positions. The second suction branch pipe 6 extends towards the ground with its inlet facing downward, suitable for collecting scattered fallen leaves. By using a first switching element and a second switching element to connect between the first and second suction branch pipes, the operator can flexibly select the suction path according to the actual position of the fallen leaves, adapting to different height suction needs without significantly altering the equipment's posture, thus improving the equipment's adaptability in complex garden environments.

[0030] As an optional implementation, such as Figure 4 , Figure 5 As shown, the first switching component includes a switching sealing tube 7, and the second switching component includes a sealing cap 8. The switching sealing tube 7 is a hollow tubular structure, and its outer diameter is clearance-fitted with the inner diameter of the first suction branch pipe 5 and the connection. The switching sealing tube 7 can be inserted into the suction main pipe 4 from the feed inlet of the first suction branch pipe 5. The tube wall of the switching sealing tube 7 is used to seal the discharge port of the second suction branch pipe 6 at the connection, and its inner cavity is used to connect the first suction branch pipe 5 and the suction main pipe 4. The sealing cap 8 is threadedly connected to the feed inlet end of the first suction branch pipe 5 and is used to close or open the feed inlet of the first suction branch pipe 5.

[0031] Furthermore, one end of the switching sealing pipe 7 is provided with an inclined end face. In the first conducting state, the inclined end face of the switching sealing pipe 7 is located outside the feed inlet of the first suction blade branch pipe, making it convenient for operators to hold and pull the switching sealing pipe 7 to achieve rapid switching between the first and second conducting states. The setting of the switching sealing pipe 7 can not only ensure that the airflow is smoothly drawn into the crushing chamber through the main suction blade pipe 4, but also effectively seal the discharge port of the unused second suction blade branch pipe 6 to prevent air leakage and a decrease in suction.

[0032] The outer wall of the feed inlet of the first suction vane branch pipe 5 is provided with an external thread section 501, and the inner wall of the cover 8 is provided with an internal thread section that matches the external thread section 501. The screw connection between the external thread section 501 and the internal thread section improves the convenience and reliability of assembling and disassembling the cover 8 and the first suction vane branch pipe 5.

[0033] When fallen leaves need to be sucked up through the first suction branch pipe 5, the cap 8 is unscrewed, and the switching sealing pipe 7 is inserted into the main suction pipe 4 through the first suction branch pipe 5. The wall of the switching sealing pipe 7 is used to seal the discharge port of the second suction branch pipe 6 at the connection point, and its inner cavity is connected to the external environment and the main suction pipe 4. Then, a suction hose is fitted onto the outer wall of the feed inlet of the first suction branch pipe 5 and fixed with a clamp. The negative pressure airflow inside the crushing chamber draws the material into the crushing chamber through the suction hose, the switching sealing pipe 7, and the main suction pipe 4, effectively increasing the operating range of the processor.

[0034] When it is necessary to suck up fallen leaves from the ground through the second suction branch pipe 6, the switching sealing pipe 7 is pulled out from the first suction branch pipe 5 to open the discharge port of the second suction branch pipe 6 at the connection point, and the sealing cap 8 is screwed onto the feed port of the first suction branch pipe 5 to close the feed port of the first suction branch pipe 5. At this time, the second suction branch pipe 6 is connected to the main suction pipe 4, and the negative pressure airflow inside the crushing chamber sucks the ground material into the crushing chamber through the second suction branch pipe 6 and the main suction pipe 4.

[0035] As an optional implementation, such as Figure 1 , Figure 2 , Figure 6 As shown, the blower pipe assembly includes a blower pipe 9, which is connected to the lower part of the vortex shell 2 and extends downward at an angle along the tangent of the vortex shell 2 so that the outlet of the blower pipe 9 faces the ground; the switching assembly includes a third switching element, which is rotatably mounted on the blower pipe 9 to open or close the outlet of the blower pipe 9, or to adjust the gas flow cross-sectional area of ​​the blower pipe 9.

[0036] The blowing pipe 9 of this invention has a dual function. In the blowing operation mode, the blowing pipe 9 is used to discharge the airflow inside the vortex shell 2 towards the ground to sweep away fallen leaves. In the shredding mode, the blowing pipe 9 also serves as a discharge channel, used to discharge the airflow carrying the crushed material inside the vortex shell 2 towards the ground. The blowing pipe 9 combines blowing and discharge functions, reducing the number of pipes and resulting in a compact structure.

[0037] As an optional implementation, such as Figure 6 As shown, the third switching component includes a valve plate 10, a rotating shaft 11, a connecting plate 12, an adjusting plate 13, and an adjusting rod 14. The valve plate 10 is rotatably connected to the discharge port of the blowing pipe 9 via the rotating shaft 11. The adjusting plate 13 has an arc-shaped structure and is set on the outer wall of the blowing pipe 9. The adjusting plate 13 has multiple adjusting holes 1301, which are spaced apart along the arc direction of the adjusting plate 13. One end of the connecting plate 12 is fixedly connected to the rotating shaft 11, and the other end has a connecting through hole 1201 for the adjusting rod 14 to pass through. After the adjusting rod 14 passes through the connecting through hole 1201, it is inserted into the corresponding adjusting hole 1301 to lock the rotation angle of the valve plate 10 relative to the blowing pipe 9.

[0038] Furthermore, the blower pipe 9 is integrally formed with the vortex shell 2 and extends along the tangential direction of the vortex shell 2. By utilizing the centrifugal force generated by the high-speed rotation of the cutter disc assembly, the airflow and crushed material in the crushing chamber are thrown out tangentially. When the material is discharged tangentially through the blower pipe 9, the centrifugal force can be fully utilized to accelerate the material, thereby improving exhaust efficiency and blower wind speed.

[0039] When the adjusting rod 14 is a smooth rod, the connecting plate 12 has a connecting through hole 1201 for the adjusting rod 14 to pass through. A spring is sleeved on the adjusting rod 14, and its two ends are connected to the adjusting rod 14 and the connecting plate 12 respectively, to provide pre-tightening force when the adjusting rod 14 is inserted into the adjusting hole 1301. When it is necessary to open or adjust the blower pipe 9, pull the adjusting rod 14 outward to disengage it from the current adjusting hole 1301. At this time, the spring is compressed. Manually rotate the valve plate 10 to the required opening angle, and then release the adjusting rod 14. The spring releases its elastic potential energy to drive the adjusting rod 14 to reset and insert into the corresponding adjusting hole 1301 to lock the rotation angle of the valve plate 10. When it is necessary to close the blower pipe 9, rotate the valve plate 10 to completely cover the outlet of the blower pipe 9, release the adjusting rod 14 so that it is inserted into the corresponding adjusting hole 1301 under the action of the spring to lock the outlet of the blower pipe 9.

[0040] When the adjusting rod 14 has a screw 25 section 1401, the connecting plate 12 has a threaded hole adapted to the screw 25 as a connecting through hole 1201. When it is necessary to open or adjust the blowing pipe 9, screw the screw 25 to disengage it from the current adjusting hole 1301, manually rotate the valve plate 10 to the required opening angle, and then screw the screw 25 in the opposite direction so that its front end is inserted into the corresponding adjusting hole 1301 to lock the rotation angle of the valve plate 10. When it is necessary to close the blowing pipe 9, rotate the valve plate 10 to completely cover the outlet of the blowing pipe 9, screw the screw 25 so that its front end is inserted into the corresponding adjusting hole 1301 to lock the position, and close the outlet of the blowing pipe 9.

[0041] As an optional implementation, such as Figure 2 As shown, the shredder pipeline assembly includes a shredder feed pipe 15, which is eccentrically disposed on the second end face 202 of the volute 2 away from the blade and extends obliquely relative to the central axis of the volute 2.

[0042] The shredded branch feed pipe 15 is eccentrically and inclinedly arranged on the second end face 202 of the vortex shell 2, so that when the branches enter the crushing chamber, they can be fed in from the tangential direction of the vortex shell 2. With the rotation of the cutter head assembly, the branches are directly cut and crushed by the high-speed rotating blades.

[0043] As an optional implementation, such as Figure 1 , Figure 2 , Figure 7 As shown, the discharge pipeline assembly includes a discharge pipe 16, which is located on the upper part of the volute 2, and its feed section extends vertically upward along the tangential direction of the volute 2; the switching assembly includes a fourth switching element, which is movably located at the connection between the feed section of the discharge pipe 16 and the volute 2, and is used to connect or disconnect the connection between the volute 2 and the discharge pipe 16.

[0044] The discharge pipe 16 of the present invention has a dual function. In the leaf suction operation mode, the discharge pipe 16 is used to discharge the airflow carrying the crushed fallen leaves in the vortex shell 2 toward the collection bag 18, realizing a complete closed-loop air path for leaf suction and material collection. In the shredding mode, the discharge pipe 16 serves as a discharge channel to guide the airflow carrying the crushed shredded material in the vortex shell 2 into the collection bag 18, realizing an integrated operation of crushing and collection.

[0045] As an optional implementation, such as Figure 7 As shown, the fourth switching component includes a switching plate 17. A plug-in groove 2041 is provided at the connection between the feed section of the discharge pipe 16 and the vortex shell 2. The switching plate 17 can be pulled out and engaged with the plug-in groove 2041 to connect or disconnect the connection between the vortex shell 2 and the discharge pipe 16.

[0046] Furthermore, an extension pipe 203 is provided on the upper part of the vortex shell 2, extending along the tangential direction of the vortex shell 2. The discharge pipe 16 is connected to the crushing chamber through the extension pipe 203. The first flange 204 of the extension pipe 203 is mated with the second flange 1601 of the discharge pipe 16 and fixedly connected by connecting bolts. An insertion groove 2041 is provided at the mating surface of the two. The switching plate 17 can be pulled out and inserted into the insertion groove 2041 to open or close the channel between the extension pipe 203 and the discharge pipe 16.

[0047] A limiting plate 1701 and a hand-held plate 1702 are provided at the end of the switching plate 17 away from the insertion slot 2041. The limiting plate 1701 is perpendicular to the switching plate 17 and is used to abut against the second flange 1601 when the switching plate 17 is fully inserted to limit the insertion depth of the switching plate 17. The hand-held plate 1702 is used by the operator to pull the switching plate 17. An extension plate 205 corresponding to the hand-held plate 1702 is provided on the first flange 204. The hand-held plate 1702 has a first fixing hole 17021, and the extension plate 205 has a second fixing hole 2051 that matches the first fixing hole 17021. The locking bolt passes through the first fixing hole 17021 and the second fixing hole 2051 and is connected to the nut to securely connect the switching plate 17 to the extension pipe 203.

[0048] When the shredded material needs to be discharged, loosen the locking bolt and remove it from the first fixing hole 17021. Pull the switching plate 17 outward using the hand lever 1702 to disengage it from the insertion slot 2041, connecting the extension pipe 203 to the discharge pipe 16. At this time, the cutter head assembly rotates at high speed, and the shredded material is thrown towards the edge of the crushing chamber under centrifugal force, and smoothly discharged along the tangential direction of the extension pipe 203 and the discharge pipe 16.

[0049] When the shredded material is not required, the switching plate 17 is reinserted into the insertion slot 2041 to the fully closed position, so that the limiting plate 1701 abuts against the second flange 1601 for positioning. Then, the locking bolts are passed through the first fixing hole 17021 and the second fixing hole 2051 in sequence and tightened with nuts to fix the switching plate 17 to the extension pipe 203, thereby closing the communication channel between the extension pipe 203 and the discharge pipe 16.

[0050] As an optional implementation, such as Figure 2 , Figure 3 As shown, the processor also includes a collection bag 18. A chute 1011 is provided on the frame 1, and a sliding frame 19 is provided on the collection bag 18. The sliding frame 19 and the chute 1011 are slidably engaged, so that the collection bag 18 can be slidably mounted on the frame 1. The opening of the collection bag 18 corresponds to the outlet of the discharge pipe 16, and is used to collect the material flowing out from the discharge pipe 16.

[0051] Furthermore, a collection frame 101 is provided on the frame 1. The collection frame 101 has a notch. The discharge pipe 16 is fixedly connected to the collection frame 101, and the discharge port of the discharge pipe 16 corresponds to the opening of the collection bag 18 through the notch, so as to guide the crushed material into the storage cavity of the collection bag 18.

[0052] A sliding frame 19 is positioned at the open end of the collection bag 18. Multiple rollers are located at the bottom of the sliding frame 19, and grooves 1011 are symmetrically arranged on the inner wall of the collection frame 101. The rollers and grooves 1011 engage in rolling motion, allowing for easy installation and removal of the collection bag 18, facilitating quick cleaning or replacement by operators. Crushed material falls directly into the collection chamber of the collection bag 18 through the discharge port and notch of the discharge pipe 16, preventing fragments from scattering on the ground.

[0053] The collection frame 101 is equipped with a first pusher 20, which makes it easy for the operator to push or pull the whole machine. The sliding frame 19 is equipped with a second pusher 21, which makes it easy for the operator to move or empty the collection bag 18 separately.

[0054] As an optional implementation, such as Figure 8 , Figure 9As shown, the processor also includes a height adjustment assembly and a front wheel assembly. The height adjustment assembly includes a fixed frame 23, an adjusting frame 24, and a screw 25. The first end of the fixed frame 23 is fixedly connected to the front wheel axle 22 located at the bottom of the frame 1. A fixing plate 26 is provided on the fixed frame 23 below the front wheel axle 22. A rotating sleeve 27 is provided at the second end of the fixed frame 23. An adjusting element 28 is provided at the first end of the adjusting frame 24. A threaded sleeve 2801 is provided on the adjusting element 28. The lower end of the screw 25 passes through the threaded sleeve 2801 and is fixed to the fixed frame 25. Plate 26 is connected, and adjusting member 28 is located above fixed plate 26 in the vertical direction; the second end of adjusting frame 24 is fixedly connected to frame 1, and a rotating shaft is provided on adjusting frame 24, which is rotatably connected to rotating sleeve 27; by turning screw 25, adjusting member 28 rises or falls along the axial direction of screw 25 to adjust the distance between fixed plate 26 and adjusting member 28, so that adjusting frame 24 swings relative to fixed frame 23 around rotating shaft, thereby driving frame 1 to rise and fall, so as to adjust the distance between the feed port of second suction leaf branch pipe 6 and the ground.

[0055] Furthermore, the second end of the adjusting frame 24 is higher than the first end of the adjusting frame 24, and the first end of the adjusting frame 24 is higher than the rotating shaft, so that the adjusting frame 24 as a whole has an asymmetrical U-shaped structure with the bottom as the fulcrum, and the side arm where the second end of the adjusting frame 24 is located is longer than the side arm where the first end of the adjusting frame 24 is located.

[0056] By rotating the screw 25, the adjusting component 28 is raised and lowered, causing the adjusting frame 24 to swing around the rotating shaft, which in turn raises and lowers the entire frame 1, thereby adjusting the distance between the feed inlet of the second suction blade branch pipe 6 and the ground. When the second suction blade branch pipe 6 needs to be close to the ground for suction, the frame 1 can be lowered; when the terrain is uneven or the second suction blade branch pipe 6 needs to be kept away from the ground, the frame 1 can be raised to adapt to different operating scenarios. Moreover, the threaded engagement between the screw 25 and the threaded sleeve 2801 is self-locking, so it is not easy for the machine to slide down on its own due to vibration after adjustment.

[0057] Specifically, when it is necessary to reduce the distance between the feed inlet of the second suction branch pipe 6 and the ground, the screw 25 is turned, the adjusting member 28 moves upward along the screw 25, the distance between the adjusting member 28 and the fixed plate 26 increases, the first end of the adjusting frame 24 moves upward accordingly, the adjusting frame 24 swings around the rotating shaft, causing the second end to descend, thereby driving the frame 1 to lower.

[0058] When it is necessary to increase the distance between the feed inlet of the second suction vane branch pipe 6 and the ground, the screw 25 is turned in the opposite direction, the adjusting member 28 moves downward along the screw 25, the distance between the adjusting member 28 and the fixed plate 26 decreases, the first end of the adjusting frame 24 moves downward accordingly, the adjusting frame 24 swings around the rotating shaft, causing the second end of the adjusting frame 24 to rise, thereby driving the frame 1 and the volute 2 to rise.

[0059] It should be noted that conventional sealing structures (such as sealing rings, sealing gaskets, etc.) in the prior art are provided at the connection between the suction blade main pipe 4 and the vortex shell 2, between the valve plate 10 and the discharge port of the blowing blade pipe 9, between the switching plate 17 and the insertion groove 2041, and at the connection between the discharge pipe 16 and the collection frame 101. These will not be elaborated on here.
