Description

Technical Field

[0001] This utility model relates to the field of wood chipper technology, and more specifically, to a baffle structure for a wood chipper and a wood chipper having the same. Background Technology

[0002] A branch shredder is a device used to crush branches. Currently, Chinese Patent Publication No. CN218167233U discloses a dynamic and static blade adjustment mechanism for a branch shredder and the shredder itself. The special structure of the baffle part satisfies the conditions for dynamic and static adjustment and facilitates chip removal. The adjustment part enables rapid adjustment of the baffle part. However, in actual use, because the gap for chip removal of the crushed branches is located between two extension bodies, the crushed branches are limited in front and behind by the two extension bodies during the chip removal process. This can easily lead to jamming in the gap between the two extension bodies, which in turn affects the normal operation of the branch shredder. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a baffle structure for a wood chipper and a wood chipper having the same, which can prevent the wood chips from getting stuck after being crushed, so as to ensure that the wood chipper can crush the wood chips normally.

[0004] This utility model provides a baffle structure for a wood chipper, including a baffle body. The baffle body is disposed in a crushing chamber inside the housing of the wood chipper, and is located on one side of the roller cutter in the crushing chamber. The baffle body includes a base plate and a protrusion disposed on the inner wall of the lower end of the base plate. The upper end of the base plate is rotatably connected to the housing located on the front and rear sides of the crushing chamber. The protrusion is located in the middle of the front and rear direction of the base plate. Notches are formed on the inner side of the lower end of the base plate and on both the front and rear sides of the protrusion. An arc-shaped surface is formed on the inner wall of the lower part of the base plate, and the lower end of the arc-shaped surface extends to the inner wall of the lower end of the protrusion. The arc-shaped surface is used to contact and cooperate with the blade of the roller cutter.

[0005] By adopting the above structure, this utility model has a notch formed on the inner side of the lower end of the substrate and on both the front and rear sides of the notch, since the protrusion is located in the middle of the front and rear direction of the substrate. After the blade of the roller cutter crushes the branches located between the baffle body and the roller cutter, the crushed branches can be discharged from the notch. The side of the notch away from the protrusion is an open structure, which can prevent the crushed branches from getting stuck, thus ensuring the normal crushing of branches by the shredder.

[0006] In one possible implementation, the length of the arc-shaped surface is greater than the distance between two adjacent cutting edges on the hob. By adopting this structure, when the baffle body rotates relative to the housing to adjust the distance between the arc-shaped surface and the cutting edge of the hob, it is possible to prevent the lower end of the baffle body from getting stuck in the gap between two adjacent cutting edges on the hob. This prevents jamming between the baffle body and the hob. In other words, during the adjustment process of the baffle body rotating relative to the housing, it is possible to prevent the rotating hob from jamming with the baffle body and causing damage to the hob.

[0007] In one possible implementation, at least one groove is provided on the inner side of the upper end of the substrate. The groove extends vertically, and the lower end of the groove extends to the upper end of the arc-shaped surface. With this structure, when the branch is inserted from the feed port on the housing, the branch can be driven between the baffle body and the roller under the rotation of the roller, and the blade on the roller can eventually crush the branch. Due to the function of the groove, the contact area between the branch and the inner side of the baffle body can be reduced, thereby reducing the friction between the branch and the baffle body, so that the branch can enter the gap between the baffle body and the roller more smoothly and be crushed by the blade of the roller.

[0008] In one possible implementation, two grooves are provided on the inner side of the upper end of the substrate, and the two grooves are spaced apart along the front-back direction of the substrate. By adopting this structure, the contact area between the tree branch and the inner side of the baffle body can be further reduced, thereby further reducing the friction between the tree branch and the baffle body, so that the tree branch can enter the gap between the baffle body and the roller cutter more smoothly and be crushed by the blade of the roller cutter.

[0009] In one possible implementation, the front and rear sides of the lower end of the substrate are both formed with inclined surfaces, which slope downwards towards the middle of the front and rear direction of the substrate. With this structure, the lower end of the substrate and the part located between the two inclined surfaces can form a contraction section. After the cutting edge of the roller cutter crushes the branches, the front and rear sides of the contraction section formed between the two inclined surfaces can avoid the crushed branches so as to facilitate the discharge of the crushed branches, thereby avoiding the situation of material jamming between the baffle body and the roller cutter.

[0010] In one possible implementation, a rotating shaft is coaxially arranged on the front and rear sides of the upper end of the substrate, and a shaft hole is provided on the housing on both the front and rear sides of the crushing chamber. Each rotating shaft is rotatably fitted in the shaft hole on the corresponding side. With this structure, the upper end of the substrate can be reliably rotatably connected to the housing under the cooperation of the rotating shaft and the shaft hole.

[0011] In one possible implementation, a plurality of reinforcing grooves are arranged in an array on the outer side wall of the substrate; by adopting this structure, the structural strength of the substrate can be improved under the action of the reinforcing grooves, that is, the structural strength of the baffle body can be improved, and the material cost of manufacturing the baffle body can be reduced.

[0012] A wood chipper includes a housing, a roller cutter, and an adjusting mechanism. A crushing chamber is formed on the inner side of the lower part of the housing, and a feed inlet is formed on the inner side of the upper part of the housing. The lower end of the feed inlet communicates with the upper end of the crushing chamber. The roller cutter is disposed in the crushing chamber and is coaxially fixed to the output shaft of a drive assembly located inside the housing. The adjusting mechanism is connected to the side wall of the housing located on one side of the crushing chamber. The wood chipper also includes the aforementioned baffle structure. The adjusting end of the adjusting mechanism abuts against the outer side wall of the lower end of the base plate. The adjusting mechanism is used to drive the base plate to rotate relative to the housing to adjust the distance between the arc-shaped surface and the blade of the roller cutter. By adopting the aforementioned baffle structure, the protrusion is located in the middle of the base plate in the front-rear direction. Notches are formed on the inner side of the lower end of the base plate and on both the front and rear sides of the protrusion. After the blade of the roller cutter crushes the branches located between the baffle body and the roller cutter, the crushed branches can be discharged from the notches. The side of the notch away from the protrusion is an open structure, which avoids the crushed branches from getting stuck, thus ensuring the normal crushing of branches by the wood chipper.

[0013] The adjustment mechanism includes a nut, an adjusting bolt, and a handle. The nut is fixed to the housing located on one side of the crushing chamber. The adjusting bolt moves from the outside to the inside through the side wall of the housing and is threadedly connected to the nut. The inner end of the adjusting bolt abuts against the outer side wall of the lower end of the base plate. The handle is coaxially sleeved and fixed to the outer end of the adjusting bolt. With this adjustment mechanism, when the handle is turned, it can drive the adjusting bolt to rotate. Under the threaded engagement of the adjusting bolt and the nut, the adjusting bolt can move inward or outward relative to the baffle body. Since the inner end of the adjusting bolt abuts against the outer side wall of the lower end of the base plate, the rotatable range of the baffle body relative to the housing can be adjusted, that is, the distance between the arc-shaped surface on the baffle body and the blade of the roller can be adjusted to meet the crushing of branches of different diameters or to change the particle size of the crushed branches.

[0022] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figure 1-6As shown in the figure, this application discloses a baffle structure for a wood chipper, including a baffle body 1. The baffle body 1 is disposed in a crushing chamber 21 inside the housing 2 of the wood chipper, and the baffle body 1 is located on one side of the roller cutter 3 in the crushing chamber 21. The baffle body 1 includes a base plate 11 and a protrusion 12 disposed on the inner wall of the lower end of the base plate 11. The upper end of the base plate 11 is rotatably connected to the housing 2 located on the front and rear sides of the crushing chamber 21. The protrusion 12 is located in the middle of the front and rear direction of the base plate 11. Notches 13 are formed on the inner side of the lower end of the base plate 11 and on both the front and rear sides of the protrusion 12. An arc-shaped surface 14 is formed on the inner wall of the lower part of the base plate 11. The lower end of the arc-shaped surface 14 extends to the inner wall of the lower end of the protrusion 12. The arc-shaped surface 14 is used to contact and cooperate with the blade 31 of the roller cutter 3.

[0025] The length of the arc surface 14 is greater than the distance between two adjacent cutting edges 31 on the hob 3. By adopting this structure, when the baffle body rotates relative to the housing to adjust the distance between the arc surface and the cutting edge of the hob, the lower end of the baffle body can be prevented from getting stuck in the gap between two adjacent cutting edges on the hob. This can prevent the baffle body and the hob from getting stuck. In other words, during the adjustment process of the baffle body rotating relative to the housing, the rotating hob and the baffle body can be prevented from getting stuck and the hob damaged.

[0026] See you again Figure 4 As shown, at least one groove 15 is provided on the inner side of the upper end of the substrate 11. The groove 15 extends in the vertical direction, and the lower end of the groove 15 extends to the upper end of the arc-shaped surface 14. With this structure, when the branch is inserted from the feed port on the housing, the branch can be driven between the baffle body and the roller under the rotation of the roller, and the blade on the roller can finally crush the branch. Due to the function of the groove, the contact area between the branch and the inner side of the baffle body can be reduced, thereby reducing the friction between the branch and the baffle body, so that the branch can enter the gap between the baffle body and the roller more smoothly and be crushed by the blade of the roller.

[0027] See you again Figure 4 As shown, two grooves 15 are provided on the inner side of the upper end of the substrate 11, and the two grooves 15 are distributed at intervals along the front-back direction of the substrate 11. By adopting this structure, the contact area between the tree branch and the inner side of the baffle body can be further reduced, thereby further reducing the friction between the tree branch and the baffle body, so that the tree branch can enter the gap between the baffle body and the roller cutter more smoothly and be crushed by the blade of the roller cutter.

[0028] See you again Figure 4As shown, inclined surfaces 16 are formed on both the front and rear sides of the lower end of the substrate 11. The inclined surfaces 16 slope from top to bottom toward the middle of the front and rear direction of the substrate 11. With this structure, the lower end of the substrate and the part located between the two inclined surfaces can form a shrinkage part. After the cutting edge of the roller cutter crushes the branches, the front and rear sides of the shrinkage part formed between the two inclined surfaces can avoid the crushed branches so as to facilitate the discharge of the crushed branches, thereby avoiding the situation of material jamming between the baffle body and the roller cutter.

[0029] See you again Figure 4 and Figure 5 As shown, rotating shafts 17 are coaxially arranged on the front and rear sides of the upper end of the substrate 11. Shaft holes 22 are provided on the housing 2 located on the front and rear sides of the crushing chamber 21. Each rotating shaft 17 is rotatably fitted in the shaft hole 22 on the corresponding side. With this structure, the upper end of the substrate can be reliably rotatably connected to the housing under the cooperation of the rotating shaft and the shaft hole.

[0030] See you again Figure 5 As shown, a plurality of reinforcing grooves 18 are arranged in an array on the outer side wall of the substrate 11. By adopting this structure, the structural strength of the substrate can be improved under the action of the reinforcing grooves, that is, the structural strength of the baffle body can be improved, and the material cost of manufacturing the baffle body can be reduced.

[0031] A wood chipper includes a housing 2, a roller cutter 3, and an adjusting mechanism. A crushing chamber 21 is formed on the inner side of the lower part of the housing 2, and a feed inlet 23 is formed on the inner side of the upper part of the housing 2. The lower end of the feed inlet 23 communicates with the upper end of the crushing chamber 21. The roller cutter 3 is disposed in the crushing chamber 21 and is coaxially fixed to the output shaft of a drive assembly located inside the housing 2. The adjusting mechanism is connected to the side wall of the housing 2 located on one side of the crushing chamber 21. The wood chipper also includes the aforementioned baffle structure. The adjusting end of the adjusting mechanism abuts against the outer side wall of the lower end of the base plate 11, and the adjusting mechanism is used for driving... The substrate 11 rotates relative to the housing 2 to adjust the distance between the arc surface 14 and the blade 31 of the roller cutter 3. After the shredder adopts the above-mentioned baffle structure, since the protrusion is located in the middle of the front-back direction of the substrate, and notches are formed on the inner side of the lower end of the substrate and on both the front and back sides of the protrusion, after the blade of the roller cutter crushes the branches located between the baffle body and the roller cutter, the crushed branches can be discharged from the notches. The side of the notch away from the protrusion is an open structure, which can prevent the crushed branches from getting stuck, so as to ensure the normal crushing of branches by the shredder.

[0032] The adjustment mechanism includes a nut 41, an adjusting bolt 42, and a handle 43. The nut 41 is fixed to the housing 2 located on one side of the crushing chamber 21. The adjusting bolt 42 is movably inserted into the side wall of the housing 2 from the outside to the inside and is threadedly connected to the nut 41. The inner end of the adjusting bolt 42 abuts against the outer side wall of the lower end of the base plate 11. The handle 43 is coaxially sleeved and fixed to the outer end of the adjusting bolt 42. With this adjustment mechanism, when the handle is turned, the handle can drive the adjusting bolt to rotate. Under the threaded action of the adjusting bolt and the nut, the adjusting bolt can move inward or outward relative to the baffle body. Since the inner end of the adjusting bolt abuts against the outer side wall of the lower end of the base plate, the rotatable range of the baffle body relative to the housing can be adjusted, that is, the distance between the arc surface on the baffle body and the blade of the roller can be adjusted to meet the crushing of branches of different diameters or to change the particle size of the crushed branches.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
