Description

Technical Field

[0001] This invention relates to the field of wood chipper technology, specifically to an orchard wood chipper with anti-jamming function. Background Technology

[0002] In orchard management and garden maintenance, branch shredders are widely used to shred pruned branches, fruit branches, and waste branches. The shredded material can be directly returned to the field or used as organic mulch, reducing waste transportation costs and achieving resource recycling. Existing branch shredders typically consist of a feed channel, a shredder disc, and a discharge channel. During operation, branches are fed into the feed channel, where they are cut and shredded by the high-speed rotating disc.

[0003] However, existing branch shredders have significant technical defects in practical use. The posture of branches in the feed channel is difficult to control. When branches enter at an angle or with forked ends, they are prone to getting stuck in the feed channel, preventing the branch ends from smoothly entering the cutter head cavity and affecting the shredding efficiency.

[0004] To address the aforementioned problems, while some existing technologies employ feeding rollers to assist in material feeding, traditional feeding rollers only provide rotary conveying functionality. When encountering irregular branches or forked branches, jamming remains a significant challenge. Therefore, improving the smoothness of branch feeding and reducing jamming issues has become a pressing technical problem to be solved in this field. Summary of the Invention

[0005] To address the problems existing in the prior art, an orchard branch shredder with anti-jamming function is provided. By setting two parallel floating rollers in the feeding channel, and a floating sleeve coaxially connected by a spline is slidably set on each floating roller, and an axial drive is set between the end of the floating sleeve and the mounting slider, the floating sleeve can reciprocate along the axial direction of the floating roller as it rotates and conveys branches, thereby generating axial vibration. This continuously dislodges branches stuck in the feeding channel and guides them smoothly into the cutter head cavity, solving the technical problem of existing branch shredders where improper branch posture or branch jamming leads to poor feeding and requires repeated manual pushing and pulling operations.

[0006] To address the problems of existing technologies, this invention provides an orchard branch shredder with anti-jamming function, comprising a shredder body having a feed channel, a discharge channel, and a cutter head cavity connecting the feed channel and the discharge channel. A branch shredder cutter head is disposed within the cutter head cavity. A rotary drive motor, connected to the branch shredder cutter head, is also disposed outside the shredder body. A branch guiding mechanism is provided in the feed channel of the shredder body. The branch guiding mechanism includes: two mounting side plates disposed on the shredder body and forming the inner wall of the feed channel, each mounted on two mounting sliders capable of moving in opposite directions; and two floating rollers disposed parallel between the two mounting side plates. The end shaft of the moving roller passes through the corresponding mounting slider and is rotatably connected to it. The end shafts of the two floating rollers are connected to the rotary drive motor. Two floating sleeves are coaxially and slidably sleeved on the corresponding floating rollers and splinedly connected to the floating rollers. An axial drive is disposed between the end of the floating sleeve and the mounting slider. When a branch enters between the two floating sleeves, the rotary drive motor drives the floating rollers and floating sleeves to rotate, while the axial drive drives the floating sleeves to reciprocate along the axial direction of the floating rollers. This causes the two floating sleeves to generate axial vibration during the rotational conveying of the branch, thereby dislodging the branch stuck in the feed channel.

[0007] Preferably, the two floating sleeves are provided with spiral patterns on their circumferential surfaces, and the spiral patterns on the floating sleeves are symmetrically distributed with respect to their central radial plane, which is used to guide the tree branch to move towards the middle position of the two floating sleeves when the floating sleeves rotate.

[0008] Preferably, the mounting side plate is provided with a mounting groove, and the two mounting sliders are slidably disposed in the mounting groove facing away from each other; the mounting side plate is also provided with a synchronous transmission assembly, which is connected to the two mounting sliders for driving the two mounting sliders to move synchronously away from the center position of the mounting groove.

[0009] Preferably, the mounting side plate is provided with a positioning groove, which extends in a direction perpendicular to the mounting slide groove. The synchronous transmission assembly includes: a synchronous block, which is slidably disposed in the positioning groove; and two connecting rods, the two ends of each connecting rod being rotatably connected to the synchronous block and the corresponding mounting slider, respectively.

[0010] Preferably, the synchronous transmission assembly further includes a first elastic reset element, which is disposed in the positioning groove and located between one end of the positioning groove and the synchronous block, for driving the synchronous block to move away from the mounting groove.

[0011] Preferably, the axial drive includes: an inclined ring disposed at the end of the floating sleeve and having an annular inclined surface facing the mounting slider; and a fixed post fixedly disposed on the mounting slider, one end of which is slidably engaged with the annular inclined surface of the inclined ring. When the floating sleeve rotates, the fixed post slides relative to the annular inclined surface, driving the floating sleeve to reciprocate along the axial direction of the floating roller.

[0012] Preferably, the axial drive further includes a second elastic reset element, which is sleeved on the floating roller and located between the end of the floating sleeve away from the inclined ring and the corresponding mounting slider.

[0013] Preferably, the axial drive further includes: a mounting cylinder, coaxially fixedly disposed on the inner circumference of one end of the floating sleeve, the outer end of the mounting cylinder forming a limiting ring, the inclined ring being sleeved on the mounting cylinder, the inner diameter of the inclined ring being larger than the outer diameter of the mounting cylinder and smaller than the outer diameter of the limiting ring; and an adjusting column, disposed circumferentially at the end of the floating sleeve along the floating roller, one end of the adjusting column being threadedly connected to the floating sleeve, and the other end abutting against the inclined ring, the tilt angle of the inclined ring being adjusted by adjusting the extension amount of each of the adjusting columns.

[0014] Preferably, a rubber sleeve is provided on the side of the mounting side plate facing the feed channel, and one end of the rubber sleeve extends to the end of the floating sleeve and is rotatably connected thereto.

[0015] Preferably, the mounting side plate is provided with two meshing gears, one of which is connected to the rotary drive motor. The mounting side plate is also provided with two tensioning pulleys. The end shaft of the floating roller, the tensioning pulleys and the gears are connected by a synchronous belt drive.

[0016] The advantages of this application compared to the prior art are: This application sets an axially sliding floating sleeve on the floating roller and uses an axial drive to generate axial vibration, so that the branches are continuously laterally moved during the feeding process, which effectively avoids feeding interruption caused by improper branch posture or branch jamming, and significantly improves the smoothness of feeding.

[0017] Each of the two floating sleeves can slide independently along the axial direction of the floating roller to accommodate differences in branch thickness. An inclined guide plate initially guides the branches at the feed inlet, ensuring they accurately enter the effective conveying area between the two floating sleeves and reducing the risk of jamming due to feed deviation. The floating sleeves and floating rollers are connected by a spline, guaranteeing reliable transmission of rotational torque while allowing the floating sleeves to slide freely axially, resulting in a compact structure and high transmission efficiency.

[0018] The end shafts of the two floating rollers are driven by the same rotary drive motor through a transmission mechanism, ensuring synchronized rotation speeds of the two floating sleeves and uniform force distribution on the branches during transport. This branch guiding mechanism utilizes the rotational power of the shredder itself, eliminating the need for an additional drive source, simplifying the structure and reducing energy consumption. This mechanism is suitable for branches of various thicknesses, dryness, wetness, and branching, significantly reducing the labor intensity of manually pushing and pulling branches and improving work efficiency and safety. The amplitude of axial vibration can be adjusted via an axial transmission device to adapt to different branch varieties and working conditions, offering good process adjustability.

Detailed Implementation

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 3 As shown, an orchard branch shredder with anti-jamming function includes a shredder body 1, which has a feeding channel 11, a discharging channel 12, and a cutter head cavity 13 connecting the feeding channel 11 and the discharging channel 12. A branch shredder cutter head 14 is provided in the cutter head cavity 13. A rotary drive motor 15 is also provided outside the shredder body and is pulverizedly connected to the branch shredder cutter head 14. A branch guiding mechanism 2 is provided in the feeding channel 11 of the shredder body 1. The branch guiding mechanism 2 includes: two mounting side plates 21, which are provided on the shredder body 1 and form the inner wall of the feeding channel 11, and each side plate is provided with two mounting sliders 211 that can move in opposite directions; and two floating rollers 22, which are arranged parallel between the two mounting side plates 21, with the end shaft of the floating rollers 22 passing through... The corresponding mounting slider 211 is inserted and rotatably connected to it. The end shafts of the two floating rollers 22 are connected to the rotary drive 15. Two floating sleeves 23 are coaxially and slidably fitted onto the corresponding floating rollers 22 and splinedly connected to the floating rollers 22. An axial drive 24 is disposed between the end of the floating sleeve 23 and the mounting slider 211. When a branch enters between the two floating sleeves 23, the rotary drive 15 drives the floating rollers 22 and the floating sleeves 23 to rotate. At the same time, the axial drive 24 drives the floating sleeves 23 to reciprocate along the axial direction of the floating rollers 22, so that the two floating sleeves 23 generate axial vibration during the rotational conveying of the branch, thereby dislodging the branch stuck in the feed channel 11.

[0032] Two floating sleeves 23 face the inlet of the feed channel 11, and two inclined guide plates 25 are symmetrically arranged on the mounting side plate 21 to guide the branches roughly into the space between the two floating sleeves 23.

[0033] When the rotary drive 15 is started, the floating roller 22 and the floating sleeve 23 begin to rotate, and the axial transmission 24 synchronously drives the floating sleeve 23 to generate axial reciprocating vibration. As long as the floating sleeve 23 remains in a rotating state, the axial vibration will continue to be generated.

[0034] During operation, branches are guided by the inclined guide plate 25 and enter between the two floating sleeves 23. The rotary drive 15 drives the floating roller 22 and the floating sleeves 23 to rotate, generating a forward conveying force on the branches. At the same time, the axial drive 24 drives the floating sleeves 23 to reciprocate along the axial direction of the floating roller 22, causing the two floating sleeves 23 to generate continuous axial vibration during the rotational conveying of branches. When the branches tilt, fork, or become partially stuck, the axial vibration of the floating sleeves 23 continuously moves the branches, changing their stress state, breaking the stuck points, and allowing the branches to smoothly pass through the gap between the floating sleeves 23 into the cutter head cavity 13, where they are cut and shredded by the branch shredder 14.

[0035] like Figure 7 and Figure 8 As shown, spiral patterns 231 are respectively provided on the circumferential surfaces of the two floating sleeves 23. The spiral patterns 231 on the floating sleeves 23 are symmetrically distributed with respect to their central radial plane, and are used to guide the tree branch to move towards the middle position of the two floating sleeves 23 when the floating sleeves 23 rotate.

[0036] The floating sleeve 23 rotates under the drive of the rotary drive 15, and the spiral patterns 231 on its surface come into contact with the tree branch. Since the spiral patterns 231 on the two floating sleeves 23 are symmetrically distributed, when the floating sleeves 23 rotate, the spiral patterns 231 exert axial thrusts in opposite directions on the tree branch, jointly guiding the branch towards the center position of the two floating sleeves 23. Under the continuous action of the spiral patterns 231, the branch maintains a centered posture throughout the conveying process, avoiding friction or jamming with the mounting side plate 21 due to deviation to one side.

[0037] The symmetrically distributed spiral pattern 231 automatically centers the branches during conveying, preventing jamming caused by branch misalignment and improving the smoothness and stability of feeding. The guiding effect of the spiral pattern 231 works in conjunction with the axial vibration of the floating sleeve 23. The former is responsible for maintaining the centered posture of the branches, while the latter is responsible for eliminating local jamming. The synergistic effect of the two significantly improves the anti-jamming effect.

[0038] like Figure 7 and Figure 8As shown, the mounting side plate 21 is provided with a mounting groove 212, and the two mounting sliders 211 are slidably disposed in the mounting groove 212 facing away from each other; the mounting side plate 21 is also provided with a synchronous transmission assembly, which is connected to the two mounting sliders 211 for driving the two mounting sliders 211 to move synchronously away from the center position of the mounting groove 212.

[0039] When processing thicker branches, the two mounting sliders 211 are driven to move synchronously in opposite directions via a synchronous transmission assembly, increasing the distance between the two floating rollers 22, allowing the thicker branches to smoothly enter between the two floating sleeves 23. When processing thinner branches, the two mounting sliders 211 are driven to move synchronously in opposite directions, decreasing the distance, allowing the two floating sleeves 23 to effectively clamp the thinner branches and generate sufficient conveying friction. During operation, the two mounting sliders 211 move in opposite directions but at equal distances, always maintaining a symmetrical distribution around the center position of the mounting groove 212, thereby ensuring that the branches are always guided to the central area of ​​the feed channel 11.

[0040] By driving two mounting sliders 211 to move synchronously in opposite directions using a synchronous transmission assembly, stepless adjustment of the distance between the two floating rollers 22 is achieved. This allows the same shredder to adapt to branches of different thicknesses, significantly improving the equipment's versatility and adaptability. The two mounting sliders 211 move symmetrically with respect to the center position of the mounting groove 212, ensuring that the branches always remain centered in the feed channel 11, avoiding uneven force distribution or skewed feeding caused by the offset of the floating rollers 22. The synchronous transmission assembly can take the form of a gear and rack pair, a double-acting lead screw, or a connecting rod 262 mechanism, etc.

[0041] like Figure 7 and Figure 8 As shown, the mounting side plate 21 is provided with a positioning groove 213, which extends in a direction perpendicular to the mounting slide groove 212. The synchronous transmission assembly includes: a synchronous block 261, which is slidably disposed in the positioning groove 213; and two connecting rods 262, the two ends of each connecting rod 262 being rotatably connected to the synchronous block 261 and the corresponding mounting slider 211, respectively.

[0042] When a branch enters between the two floating sleeves 23, the diameter of the branch pushes the two floating sleeves 23 and the corresponding mounting sliders 211 to move backward. The backward movement of the mounting sliders 211 drives the synchronizing block 261 to slide backward along the positioning groove 213 via the connecting rod 262. At the same time, the linkage of the connecting rod 262 makes the two mounting sliders 211 move equal distances but in opposite directions. After the branch passes, the synchronizing block 261 and the two mounting sliders 211 automatically reset under the action of the elastic reset element. Through the above linkage mechanism, the distance between the two floating rollers 22 can be adaptively adjusted according to the diameter of the branch.

[0043] The opposing movement of the two mounting sliders 211 is directly driven by the inserted branch, eliminating the need for manual adjustment or additional drive devices. This achieves adaptive spacing adjustment and makes the device more convenient to use. The linkage mechanism 262 ensures that the two mounting sliders 211 move the same distance, keeping the two floating rollers 22 symmetrical with respect to the centerline of the feed channel 11. This ensures the branch is guided to the center position and avoids jamming due to deviation to one side. When the branch diameter is uneven, the two mounting sliders 211 can float in real time according to the change in branch diameter, keeping the two floating sleeves 23 in contact with the branch at all times. This ensures both conveying friction and avoids jamming due to excessively small gaps.

[0044] like Figure 7 and Figure 8 As shown, the synchronous transmission assembly further includes a first elastic reset element 263, which is disposed in the positioning groove 213 and located between one end of the positioning groove 213 and the synchronous block 261, for driving the synchronous block 261 to move away from the mounting slide groove 212.

[0045] When the branch enters between the two floating sleeves 23, the diameter of the branch pushes the two floating sleeves 23 and the mounting slider 211 to move backward. The mounting slider 211, through the connecting rod 262, drives the synchronizing block 261 to overcome the elastic force of the first elastic reset element 263 and slide backward along the positioning groove 213. After the branch passes, the pushing force of the branch on the floating sleeves 23 disappears, and the first elastic reset element 263 releases its elastic potential energy, pushing the synchronizing block 261 to move and reset away from the mounting groove 212. The synchronizing block 261, through the connecting rod 262, drives the two mounting sliders 211 to move and reset towards each other, so that the two floating sleeves 23 return to their initial spacing, preparing for the next feeding.

[0046] The first elastic reset element 263 realizes the automatic reset of the synchronization block 261 and the mounting slider 211 without manual intervention or additional driving device, ensuring the automatic restoration of the spacing of the floating roller 22 after each feeding, and improving the automation level and continuous operation capability of the equipment.

[0047] like Figure 5 , Figure 6 , Figure 9 and Figure 10As shown, the axial transmission device 24 includes: an inclined ring 241 disposed at the end of the floating sleeve 23 and having an annular inclined surface facing the mounting slider 211; and a fixed column 242 fixedly disposed on the mounting slider 211, one end of which is slidably engaged with the annular inclined surface of the inclined ring 241. When the floating sleeve 23 rotates, the fixed column 242 slides relative to the annular inclined surface, driving the floating sleeve 23 to reciprocate along the axial direction of the floating roller 22.

[0048] The floating sleeve 23 rotates under the drive of the rotary drive 15, while the fixed column 242 remains stationary. The balls 243 at the end of the fixed column 242 roll along the annular inclined surface of the inclined ring 241. Because the annular inclined surface has a smooth sloping transition in the circumferential direction, the balls 243 push the inclined ring 241 and the floating sleeve 23 to reciprocate axially along the floating roller 22 during rolling. The arrangement of the balls 243 changes the contact between the fixed column 242 and the inclined ring 241 from sliding friction to rolling friction, guiding the floating sleeve 23 to stably generate axial reciprocating movement with relatively small resistance.

[0049] The engagement of the inclined ring 241 and the fixed column 242 converts the rotational motion of the floating sleeve 23 into axial reciprocating movement. The axial travel and motion pattern of the floating sleeve 23 can be precisely controlled via the smoothly transitioning annular inclined surface, eliminating the need for a complex reversing mechanism. Since the floating sleeve 23 and the floating roller 22 are connected by a spline, the transmission of rotational torque is unaffected during axial vibration. The direction of axial vibration is perpendicular to the feeding direction of the branches; therefore, the vibration does not push the branches outward but rather laterally displaces them, helping to break up jamming points without affecting the feeding direction.

[0050] like Figure 5 and Figure 9 As shown, the axial drive 24 further includes a second elastic reset element 244, which is sleeved on the floating roller 22 and located between the end of the floating sleeve 23 away from the inclined ring 241 and the corresponding mounting slider 211.

[0051] When the fixed column 242 slides relative to the annular inclined surface of the inclined ring 241, the inclined ring 241 pushes the floating sleeve 23 to move axially away from the inclined ring 241 along the floating roller 22. At this time, the floating sleeve 23 compresses the second elastic reset element 244, causing it to store elastic potential energy. When the annular inclined surface of the inclined ring 241 passes its highest point, the second elastic reset element 244 releases its elastic potential energy, pushing the floating sleeve 23 to move in the opposite direction towards the inclined ring 241 to reset. During the continuous rotation of the floating sleeve 23, the periodic engagement between the fixed column 242 and the annular inclined surface, as well as the periodic reset of the second elastic reset element 244, jointly drive the floating sleeve 23 to produce continuous axial reciprocating movement.

[0052] The second elastic reset element 244 provides a reset force for the reverse movement of the floating sleeve 23, enabling the floating sleeve 23 to automatically reset after completing axial movement in one direction, thus forming a complete reciprocating cycle and ensuring the continuity of axial vibration. The second elastic reset element 244 and the annular inclined surface of the inclined ring 241 together constitute a bidirectional drive mechanism. The inclined ring 241 provides a positive thrust, and the second elastic reset element 244 provides a reverse reset force. The two work together to ensure that the floating sleeve 23 can controllably reach the preset position and reset on time in each axial stroke, thereby forming a reciprocating vibration with stable frequency and amplitude, avoiding the amplitude attenuation or stroke loss of control that occurs in the reverse stroke due to reliance on inertia in the traditional unidirectional drive scheme.

[0053] like Figure 6 and Figure 10 As shown, the axial transmission device 24 further includes: a mounting cylinder 245, coaxially fixedly disposed on the inner circumference of one end of the floating sleeve 23, a limiting ring 2451 formed at the outer end of the mounting cylinder 245, an inclined ring 241 sleeved on the mounting cylinder 245, the inner diameter of the inclined ring 241 being larger than the outer diameter of the mounting cylinder 245 and smaller than the outer diameter of the limiting ring 2451; and an adjusting column 246, disposed circumferentially at the end of the floating sleeve 23 along the floating roller 22, one end of the adjusting column 246 being threadedly connected to the floating sleeve 23, and the other end abutting against the inclined ring 241, the tilt angle of the inclined ring 241 being adjusted by adjusting the extension amount of each of the adjusting columns 246.

[0054] Rotating each adjusting column 246 changes its extension length. Since the adjusting columns 246 are distributed circumferentially along the floating sleeve 23, by independently adjusting the extension of the adjusting columns 246 at different positions, the tilting ring 241 can be tilted to different degrees. After the tilt angle of the tilting ring 241 changes, the contact position and contact angle between its annular tilted surface and the fixed column 242 also change, thus affecting the axial movement stroke of the floating sleeve 23. When the tilt angle of the tilting ring 241 increases, the axial displacement generated by the sliding of the fixed column 242 along the annular tilted surface increases, and the axial movement stroke of the floating sleeve 23 increases; when the tilt angle of the tilting ring 241 decreases, the axial movement stroke decreases accordingly. The limiting ring 2451 prevents the tilting ring 241 from dislodging from the mounting cylinder 245 during the rotation or axial movement of the floating sleeve 23.

[0055] By adjusting the extension of each adjusting column 246, the tilt angle of the tilting ring 241 can be flexibly changed, thereby adjusting the stroke of the axial reciprocating movement of the floating sleeve 23, realizing stepless adjustment of the axial vibration amplitude, and adapting to the anti-jamming requirements of different tree branch varieties and working conditions.

[0056] like Figure 7As shown, a rubber sleeve 27 is provided on the side of the mounting side plate 21 facing the feeding channel 11, and one end of the rubber sleeve 27 extends to the end of the floating sleeve 23 and is rotatably connected to it.

[0057] A bearing is provided between the floating sleeve 23 and the end of the rubber sleeve 27 when the floating sleeve 23 rotates. The rubber sleeve 27 covers the side of the mounting side plate 21 facing the feed channel 11, and one end of it is rotatably connected to the end of the floating sleeve 23, adapting to the rotation and axial movement of the floating sleeve 23. The rubber sleeve 27 isolates the mounting groove 212, positioning groove 213 and internal transmission components on the mounting side plate 21 from the feed channel 11. Debris generated by branches during the conveying process is blocked by the rubber sleeve 27 and cannot enter the groove on the mounting side plate 21. Since the rubber sleeve 27 is rotatably connected to the floating sleeve 23, the rotation and axial movement of the floating sleeve 23 are not hindered by the rubber sleeve 27, and the elastic deformation of the rubber sleeve 27 can adapt to the axial movement stroke of the floating sleeve 23.

[0058] like Figure 4 and Figure 7 As shown, the mounting side plate 21 is provided with two meshing gears 281. One of the gears 281 is connected to the rotary drive motor 15. The mounting side plate 21 is also provided with two tensioning wheels 282. One of the gears 281 is driven to rotate by the rotary drive motor 15, and the other gear 281 meshes with it to achieve reverse rotation. The output shafts of the two gears 281 are each provided with a synchronous pulley, which drives the synchronous pulley on the end shaft of the corresponding floating roller 22 through the synchronous belt. The tensioning wheel 282 presses against the inside of the synchronous belt to maintain tension.

[0059] The mounting side plate 21 is provided with a guide groove 214 parallel to the mounting slide 212. A tensioning block and a tensioning spring 283 are provided in the guide groove 214, and a tensioning wheel 282 is rotatably mounted on the tensioning block.

[0060] The rotary drive 15 drives the end shafts of two floating rollers 22 to rotate synchronously via gear 281 and a timing belt. A tension spring 283 applies a preload force along the guide groove 214 to the tensioning block, ensuring that the tensioning wheel 282 always presses against the timing belt. When the timing belt slightly elongates due to long-term use, the tension spring 283 automatically pushes the tensioning block to compensate for the elongation and maintain a constant tension. The guide groove 214 guides the movement of the tensioning block, ensuring that the direction of movement of the tensioning wheel 282 is consistent with the tensioning direction of the timing belt.

[0061] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
