[0028] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0029] This application discloses a diesel-powered tree branch shredder, referring to... Figure 1 and Figure 2In this embodiment, the diesel-powered wood chipper includes a chassis 1, a feeding device 2, a crushing device 3, and a tracked walking device 4. The feeding device 2 is mounted on the front side of the chassis 1 to effectively feed wood branches and timber. The crushing device 3 is mounted on the rear side of the feeding device 2 to crush the wood branches and timber fed in from the feeding device 2, and then transport the crushed wood fragments to the outside of the crushing device 3. The tracked walking device 4 is mounted on the bottom of the chassis 1 to facilitate moving the entire chipper to a designated location.

[0030] Specifically, refer to Figures 2-5 In this embodiment, the feeding device 2 includes a feeding cover 21, a feeding roller chamber 22, a feeding roller floating frame 23, a guiding linkage mechanism 24, a feeding motor 25, a feeding roller cutter 26, a feeding roller adjustment mechanism 27, and a feeding mechanism 28. The feeding hood 21 is installed on the front top of the walking chassis 1; the feeding roller chamber 22 is installed at the discharge port of the feeding hood 21; the feeding roller floating frame 23 is slidably installed on the outside of the feeding roller chamber 22 through the guide linkage mechanism 24, and the feeding roller floating frame 23 includes two inverted L-shaped plates, each with a connecting end installed on one side of its top. The two connecting ends are clamped together and then fixedly connected by a bolt and nut structure, so that the other ends of the two inverted L-shaped plates slide against the two outer sides of the feeding roller chamber 22 respectively. In this way, by setting the guide linkage mechanism 24, the feeding roller floating frame 23 can effectively guide and limit the movement, so that the feeding roller floating frame 23 can slide up and down on the outside of the feeding roller chamber 22.

[0031] More specifically, in this embodiment, the guiding linkage mechanism 24 includes a long guide plate 241, a first fixing member 242, a linkage rod 243, a second fixing member 244, a top block 245, a third fixing member 246, and a top cover 247. The feed roller chamber 22 has four long guide plates 241, which are arranged in pairs. The two pairs of long guide plates 241 are symmetrically located on the two outer sides of the feed roller chamber 22. The long guide plates 241 are securely installed on the two outer sides of the feed roller chamber 22 by multiple fasteners 242. Preferably, the fasteners 242 are bolts. By using these bolts to symmetrically install the long guide plates 241 on the two outer sides of the feed roller chamber 22, one side of the feed roller floating frame 23 abuts between two long guide plates 241 located on the same side, and the other side abuts between two other long guide plates 241 located on the same side. This guides and limits the two ends of the feed roller floating frame 23, allowing the feed roller floating frame 23 to slide between the long guide plates 241.

[0032] Meanwhile, both ends of the linkage rod 243 are connected between the two inner sides of the feed roller floating frame 23 via fixing parts 244. Guide holes that cooperate with the linkage rod 243 are provided on both sides of the feed roller chamber 22. The two ends of the linkage rod 243 extend outwards along the two guide holes and abut against the two inner sides of the feed roller floating frame 23. Preferably, the fixing part 244 includes a screw connected to one end of the linkage rod 243. Holes are provided on both sides of the 3 to cooperate with the screw, so that the screw passes through the outside of the feed roller floating frame 23 along the holes. Nuts are threaded on both screws. By screwing the two nuts into the two screws respectively, the two nuts are pressed against the two outer sides of the feed roller floating frame 23, so that the linkage rod 243 can be firmly installed on the two inner sides of the feed roller floating frame 23, thereby improving the stability and integrity of the feed roller floating frame 23 when sliding up and down.

[0033] In addition, there are two abutment blocks 245. Both abutment blocks 245 are installed on the inner top side of the feed roller floating frame 23 by fixing member three 246. When the feed roller floating frame 23 slides down, the two abutment blocks 245 abut against the top of the feed roller chamber 22, so that the two abutment blocks 245 can block the position of the feed roller floating frame 23, thereby preventing the inner top side of the feed roller floating frame 23 from colliding with the top of the feed roller chamber 22. Preferably, the fixing member 246 includes a screw connected to the top of the abutment block 245. A hole is provided on the top side of the feed roller floating frame 23 to cooperate with the screw. The screw passes through the hole and extends out of the top side of the feed roller floating frame 23. A nut is threaded onto the screw. By screwing the nut into the screw, the nut is pressed against the top side of the feed roller floating frame 23, thereby securing the abutment block 245 on the feed roller floating frame 23.

[0034] Furthermore, the top cover 247 is installed between the top rear side of the feed cover 21 and the top rear side of the feed roller chamber 22, and the top cover 247 covers the outside of the feed roller floating frame 23; by setting the top cover 247, the components on the feed roller floating frame 23 and the feed roller chamber 22 can be effectively protected.

[0035] Secondly, refer to Figure 3 and Figure 4In this embodiment, the feeding motor 25 is installed on one side of the feeding roller floating frame 23; one end of the feeding roller cutter 26 is installed at the output end of the feeding motor 25, and the other end is rotatably connected to the other side of the feeding roller floating frame 23. The feeding roller cutter 26 is located inside the feeding roller chamber 22, and both ends of the feeding roller cutter 26 respectively cooperate with two guide holes, so that both ends of the feeding roller cutter 26 extend out of the feeding roller chamber 22 along the two guide holes, thereby enabling the feeding roller cutter 26 and the feeding motor 25 to move up and down with the feeding roller floating frame 23. When the feeding motor 25 is started, the output end of the feeding motor 25 drives the feeding roller cutter 26 to rotate at high speed, so as to effectively transport the branches entering from the feeding cover 21.

[0036] At the same time, refer to Figure 3 and Figure 4 In this embodiment, the feed roller adjustment mechanism 27 is installed between the feed roller chamber 22 and the feed roller floating frame 23 to achieve elastic reset of the movement of the feed roller floating frame 23, thereby enabling the feed roller to transport branches of different sizes, thus ensuring both high practicality and work efficiency. More specifically, in this embodiment, the feed roller adjustment mechanism 27 includes an adjustment plate 271, an adjustment screw 272, an adjustment component 273, an adjustment block 274, and a tension spring 275. Two adjustment plates 271 are provided, symmetrically installed at the bottom outer sides of the feed roller chamber 22, and each adjustment plate 271 has an adjustment groove. These two adjustment grooves respectively cooperate with the two ends of the feed roller floating frame 23, allowing the two ends of the feed roller floating frame 23 to slide along the two adjustment grooves on the two adjustment plates 271.

[0037] Two adjusting screws 272 are provided. The two adjusting screws 272 are respectively installed on the two adjusting plates 271 through adjusting components 273. The adjusting component 273 includes two adjusting nuts located on the upper and lower sides of the adjusting plate 271 respectively. The adjusting screw is threadedly connected to the two adjusting nuts. The adjusting plate 271 has adjusting holes that communicate with the two adjusting nuts. The adjusting screw passes through the adjusting plate 271 along the adjusting holes. In this way, the adjusting screw can be installed on the adjusting plate 271 through the mating structure of the adjusting nuts and the adjusting screw threadedly connected. Two adjusting blocks 274 are provided, and the two adjusting blocks 274 are symmetrically installed at the top of the two outer sides of the feed roller floating frame 23; two tension springs 275 are provided, and the two tension springs 275 are symmetrically located on the two outer sides of the feed roller floating frame 23, and the two ends of the tension springs 275 are respectively connected between one side of the adjusting block 274 and one end of the adjusting screw 272, so as to realize the elastic traction of the feed roller floating frame 23.

[0038] At the same time, refer to Figure 1and Figure 5 In this embodiment, the feeding mechanism 28 is installed at the feed port of the feeding hood 21. By setting the feeding mechanism 28, it is not only convenient to carry and place the branches, thereby pushing the branches into the feeding hood 21 in an orderly manner, but also the feed port of the feeding hood 21 can be closed when no operation is required. More specifically, in this embodiment, the feeding mechanism 28 includes a feeding flap 281, a flap stop 282, a stop tube 283, a hook 284, a rotating component 285, a curtain 286, a first positioning component 287, a stop seat 288, a feeding control lever 289, and a second positioning component 290.

[0039] The feeding flap 281 is rotatably mounted on one side at the bottom of the feed port of the feeding hood 21. Two flap blocks 282 are provided, and the two flap blocks 282 are symmetrically mounted on the side of the feeding flap 281 near the feeding hood 21. The baffle tube 283 is installed at the bottom front end of the feeding hood 21, and the baffle tube 283 cooperates with the two flap blocks 282. When the feeding flap 281 flips downward, the two flap blocks 282 are locked onto the baffle tube 283, so that the feeding flap 281 and the inner bottom side of the feeding hood 21 are parallel to each other, so as to effectively support the branches, and thus allow the operator to push the branches on the feeding flap 281 into the feeding hood 21 in an orderly manner.

[0040] The hook 284 is rotatably mounted on the top front end of the feed cover 21 via a rotating component 285. The rotating component 285 includes rotating blocks symmetrically mounted on the top front end of the feed cover 21, with a rotating pin rotatably mounted between the two rotating blocks. One end of the hook 284 is mounted on the outside of the rotating pin, and a hook hole is provided on the side of the feed flap 281 facing away from the feed cover 21. The hook hole hooks with the hook 284. When the feed flap 281 is flipped upward to cover the front side of the feed cover 21, the hook 284 is rotated so that the end of the hook 284 is engaged in the hook hole, thereby achieving a stable and limited position of the feed flap 281, and thus the feed flap 281 is stably covered at the feed port of the feed cover 21.

[0041] Preferably, the baffle 286 is installed at the feed port of the feed hood 21 via a positioning component 287. The positioning component 287 includes several bolts and a pressure plate installed at the top front side of the feed hood 21 via the bolts. The pressure plate firmly presses the baffle 286 onto the feed hood 21, thus providing safety protection and controlling the feed. Simultaneously, two baffle seats 288 are provided, symmetrically installed on the front side of the pressure plate of the positioning component 287. When the feed flap 281 flips upward to cover the front side of the feed hood 21, the two baffle seats 288 respectively cooperate with one side of the feed flap 281 to block the feed flap 281, thereby preventing the feed flap 281 from colliding with the feed hood 21.

[0042] In addition, the feeding control lever 289 is installed on the outside of the feeding cover 21 by the positioning component 290. The positioning component 290 includes a positioning plate and multiple bolts. The positioning plate is installed on the top side of the feeding cover 21 by the multiple bolts. The outer side of the positioning plate is provided with a positioning groove that cooperates with and abuts against one side of the feeding control lever 289, thereby enabling the feeding control lever 289 to be stably positioned, and thus the feeding cover 21 can be controlled by the feeding control lever 289.

[0043] Specifically, refer to Figure 1 , Figure 6 and Figure 7 In this embodiment, the crushing device 3 includes a crushing chamber 31, a crushing drum 32, a crushing blade assembly 33, a discharge fan plate 34, an upper throwing cylinder 35, a rear box cover 36, a crushing drive mechanism 37, and a linkage adjustment mechanism 38. The crushing chamber 31 is installed at the discharge port of the feed roller chamber 22; the crushing roller 32 is rotatably installed inside the crushing chamber 31, and the crushing roller 32 includes a roller shaft rotatably installed on the two inner sides of the crushing chamber 31 at both ends. A front plate, a middle plate and a rear plate are installed on the outer side of the roller shaft, and two feed crushing ports are opened on the front plate. The two feed crushing ports are respectively matched with the discharge port of the feed roller chamber 22; multiple crushing blade groups 33 are provided, and multiple crushing blade groups 33 are installed between the front plate and the middle plate; multiple discharge fan plates 34 are provided, and multiple discharge fan plates 34 are respectively installed between the middle plate and the rear plate; the upper throwing cylinder 35 is installed on the outer top of the crushing chamber 31, and the feed end of the upper throwing cylinder 35 is located between the middle plate and the rear plate.

[0044] When the crushing drum 32 rotates, it drives the crushing blade assembly 33 and the discharge fan plate 34 to rotate simultaneously. The branches conveyed from the feed roller chamber 22 then enter the crushing chamber 31 sequentially along the feed crushing inlet. The crushing blade assembly 33 then crushes the branches to obtain small pieces. These small pieces are then blown into the upper throwing cylinder 35 by the rotating discharge fan plate 34, and finally discharged from the upper throwing cylinder 35 to the outside of the crushing chamber 31. Preferably, the direction of the upper throwing cylinder 35 can be adjusted 360 degrees, thereby discharging the small pieces to a designated position. Furthermore, a guide plate 351 is installed on the outer side of the discharge end of the upper throwing cylinder 35, which also allows for adjustment of the direction of the discharged small pieces.

[0045] At the same time, refer to Figure 1 , Figure 7 and Figure 8 In this embodiment, the rear box cover 36 is installed on the top of the rear end of the walking chassis 1; the crushing drive mechanism 37 is installed inside the rear box cover 36; the linkage adjustment mechanism 38 is arranged between the output end of the crushing drive mechanism 37 and the input end of the crushing drum 32, so as to drive the crushing drum 32 to rotate.

[0046] More specifically, in this embodiment, the crushing drive mechanism 37 includes an engine 371, a diesel tank 372, and a battery 373. The engine 371 is connected to both the diesel tank 372 and the battery 373. Diesel fuel from the diesel tank 372 powers the engine 371, and the battery 373 powers both the engine and other components of the branch shredder. The front output of the engine 371 is connected to the input of the crushing drum 32 via a linkage adjustment mechanism 38, allowing the power from the engine 371 to be transmitted to the crushing drum 32. The crushing drum 32 then drives the shredder blade assembly 33 to rotate, chopping and crushing the fed branches. The crushing drum 32 also drives the discharge fan 34 to rotate, discharging the crushed material outside the crushing chamber 31.

[0047] In addition, a radiator assembly 374 is installed at the rear output end of the engine 371, and a filter screen 375 that cooperates with the radiator assembly 374 is installed at the rear end of the rear cover 36. The radiator assembly 374 can effectively dissipate heat from the rear cover 36, thereby ensuring the normal operation of the equipment inside the rear cover 36. The filter screen 375 can effectively filter the hot air blown out by the radiator assembly 374.

[0048] More specifically, refer to Figure 8 and Figure 9In this embodiment, the linkage adjustment mechanism 38 includes an output pulley 381, a crushing drum pulley 382, ​​a linkage belt 383, a tensioning pivot 384, a tensioning sleeve 385, a tensioning arm 386, a tensioning wheel 387, and an elastic adjustment assembly 39.

Through the rotation of gears inside the walking gearbox 412, power is transmitted to the drive shafts 42 via the gear train, thereby causing the drive shafts 42 to drive the drive wheels 43 to rotate. Preferably, there are two half-shaft sleeves 414, which are respectively installed on both sides of the travel gearbox 412, and are respectively sleeved on the outside of the two drive shafts 42, so as to effectively support and protect the drive shafts 42.

[0053] Preferably, in this embodiment, a hydraulic device 5 is also installed on one side of the middle of the walking chassis 1. This hydraulic device 5 is located on one side of the crushing chamber 31 and is connected to both the walking motor 413 and the feeding motor 25 to enable forward and reverse rotation and stop operations of the feeding motor 25 and the walking motor 413, thereby completing the entire process of feeding, crushing, and discharging the branches. Specifically, this hydraulic device 5 is existing technology and will not be described in detail here. Simultaneously, the hydraulic circuits of the walking motor 413 and the feeding motor 25 are interlocked in the electrical control system, preventing them from operating simultaneously and ensuring safety.

[0054] In this embodiment, two guide wheels 44 are provided, each rotatably mounted on both sides of the rear end of the chassis 1 via a guide wheel adjustment mechanism 45. Two rubber tracks 46 are provided, each fitted between one guide wheel 44 and one drive wheel 43 to facilitate the unfolding of the rubber tracks 46.

Furthermore, two track adjustment mechanisms 47 are provided, symmetrically mounted on both sides of the chassis 1, and each mechanism cooperates with the inner side of the two rubber tracks 46, further enabling effective adjustment of the tension of the two rubber tracks 46.

[0055] More specifically, the guide wheel adjustment mechanism 45 includes a tensioning sleeve 451, a tensioning rod 452, a tensioning U-shaped frame 453, a chassis frame 454, a tensioning plate 455, a tensioning screw 456, an adjusting element 457, a knob 458, and a tensioning support plate 459.

One end of the tensioning screw 456 extends into the interior of the tensioning sleeve 451 along the hole and is rotatably connected to the end of the tensioning rod 452 away from the tensioning U-shaped frame 453.

[0056] Meanwhile, the adjusting component 457 is a tensioning nut installed on one side of the tensioning plate 455. The tensioning nut is threadedly connected to the tensioning screw 456, and the knob 458 is installed on the end of the tensioning screw 456 away from the tensioning sleeve 451. The tensioning support plate 459 is installed at the bottom of the tensioning U-shaped frame 453, and the tensioning support plate 459 cooperates with the outer side of the tensioning rod 452 near the tensioning U-shaped frame 453 to support the tensioning rod 452. When the knob 458 is rotated, the tensioning screw 456 rotates inside the tensioning nut, causing the tensioning rod 452 to slide left and right inside the tensioning sleeve 451. This causes the tensioning rod 452 to drive the guide wheel 44 on the tensioning U-shaped frame 453 to move left and right, thereby effectively adjusting the tension of the rubber track 46.

[0057] More specifically, the track adjustment mechanism 47 includes a support roller plate 471, an adjusting support roller 472, a support roller 473, a guide rail rod 474, a guide rail plate 475, and a track guide rail 476.

Two adjusting support rollers 472 are provided, symmetrically rotatably mounted on the two inner sides of the top of the support roller plate 471, and each adjusting support roller 472 abuts against the inner top of the rubber track 46. Multiple support rollers 473 are provided, each rotatably mounted on the inner bottom of the chassis frame 454 via pins, and each support roller 473 abuts against the inner bottom of the rubber track 46, thereby effectively deploying and guiding the rubber track 46.

[0058] Meanwhile, multiple guide rail rods 474 are provided, and these guide rail rods 474 are respectively installed on the bottom inner side of the chassis frame 454; multiple guide rail plates 475 are provided, and the number of guide rail plates 475 is the same as the number of guide rail rods 474, and these guide rail plates 475 are respectively installed on the outer bottom of the guide rail rods 474; the outer side of the track guide rail 476 is fixedly connected to the side of the guide rail plates 475 away from the guide rail rods 474, and the track guide rail 476 abuts against the inner bottom of the rubber track 46 to effectively prevent the rubber track 46 from deviating. Preferably, in this embodiment, the combined structure of the guide rail plates 475 and guide rail rods 474 and the design of the support rollers 473 are staggered.

[0059] When the wood chipper travels in a straight line, the power from engine 371 is evenly transmitted to the rubber tracks 46 on the left and right sides via travel motor 413 and travel gearbox 412. Simultaneously, referring to... Figure 1 and Figure 10 In this embodiment, a control box 6 connected to the walking gearbox 412 body is also installed on the front side of the walking chassis 1. The control box 6 is equipped with left and right steering handles. When turning, the gears inside the walking gearbox 412 body are engaged and disengaged by operating the left and right steering handles to achieve left and right differential speed, thereby realizing the steering movement.

[0060] In addition, a driving control lever is installed on the control box 6. When the driving control lever is in the stop position, the machine is in parking mode. A reverse stop lever is also installed on the front side of the control box 6. When the operator operates the machine from one side of the control box 6, the reverse stop lever will rebound when it encounters an obstacle while the machine is reversing, stopping the machine. Simultaneously, a feeding handle is also installed on the control box 6. This feeding handle is electrically connected to the feeding motor 25. By operating the feeding handle, a sensor switch is activated, driving the feeding motor 25 to rotate forward / reverse, thus enabling the branch shredder to perform the feeding / unloading process.

[0061] In addition, refer to Figure 1 and Figure 2 In this embodiment, in order to facilitate the hoisting and transportation of the entire branch shredder, a hoisting pallet 7 is installed on the rear side of the shredding box. The hoisting pallet 7 has a hoisting hole. The crane hook is hooked into the hoisting hole on the hoisting pallet 7, thereby enabling the hoisting and transportation of the entire branch shredder.

[0062] Therefore, the present application solution, by setting up a structure in which the walking chassis 1, feeding device 2, crushing device 3 and tracked walking device 4 cooperate with each other, can achieve the effect of automatically crushing branches and wood, thereby crushing branches and wood into small pieces, and making the crushing of branches and wood more thorough; at the same time, the structure of the branch crusher is compact and occupies a small area, and the setting of the tracked walking device 4 makes the whole branch crusher more convenient to move, can move to a designated location, and can adapt to various terrains for stable movement.
