Description

Technical Field

[0001] This utility model belongs to the field of grape branch crushing technology, and more specifically, it relates to a grape branch rake device for a crusher. Background Technology

[0002] In the viticulture industry, winter pruning generates a large number of unused grape branches. These branches, scattered in the fields, can hinder subsequent field operations such as tilling and fertilization if not handled promptly and effectively. They can also become breeding grounds for pests and diseases, posing a potential threat to the healthy growth of grapes the following year.

[0003] Currently, tractor-drawn or suspended branch shredders are commonly used to shred and return branches to the field. This mechanized operation can shred most branches into small pieces or sawdust, allowing them to decompose quickly, thereby increasing the soil's organic matter content and achieving resource recycling.

[0004] However, in practical applications, existing shredding equipment still has significant technical shortcomings. Because grapevines vary in length, are curved, and intertwined, some longer or more flexible vines are easily bounced off the shredding rotor or dragged out of the shredding chamber without being fully grasped during the shredding process. As a result, a large number of long, incompletely shredded vines often remain on the field surface after shredding. These remaining long vines directly affect the return of the grapes to the field, forcing farmers to perform secondary manual cleaning or re-shredding, significantly increasing operating time and production costs, and reducing overall operational efficiency. Utility Model Content

[0005] This utility model provides a grape vine rake device for a crusher, which can improve the thoroughness of a single crushing operation, thereby avoiding secondary manual cleaning or re-crushing, saving operation time and production costs, and improving overall operation efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a grape vine raking device for a crusher is provided. The crusher includes a tractor, a crushing mechanism disposed on the rear side of the tractor, and a cover covering the crushing mechanism. The grape vine raking device includes a mounting base and a plurality of raking components. The mounting base is disposed on the rear side wall of the cover, and a mounting rod extending in the left-right direction is provided on the rear side of the mounting base. The plurality of raking components are spaced apart on the mounting rod along the axial direction. Each raking component includes a sliding sleeve slidably sleeved on the outer periphery of the mounting rod and a raking rod disposed at the bottom of the sliding sleeve. The sliding sleeve is locked by a locking member, and the raking rod extends downward for hooking grape vines.

[0007] In one possible implementation, a first locking hole is provided through the mounting rod in the front-back direction, and several first locking holes are spaced apart along the axial direction of the mounting rod. A second locking hole is provided through the sliding sleeve in the front-back direction, and a locking member passes through the second locking hole and one of the first locking holes in the front-back direction.

[0008] In some embodiments, the first locking hole is elliptical in shape, and the locking element is elliptical in shape to fit the first locking hole.

[0009] In some embodiments, a limiting member is axially provided on the locking member, and an elliptical limiting piece is provided at the front end of the limiting member. The limiting piece is adapted to the first locking hole. The limiting member can drive the limiting piece to rotate and enable the limiting piece to contact and cooperate with the side wall of the mounting rod to prevent the locking member from disengaging from the first locking hole.

[0010] In some embodiments, the rear end of the locking member is provided with a limiting platform that protrudes outward and is used to contact and engage with the rear sidewall of the sliding sleeve.

[0011] In some embodiments, the rear end of the limiting member is provided with a mounting platform that protrudes outward.

[0012] In some embodiments, an elastic element is sleeved on the outer periphery of the limiting member, and the elastic element is located between the locking member and the mounting platform for elastically pushing the mounting platform.

[0013] In one possible implementation, the mounting base is connected to the housing by a fastener, which includes a fixing nut and a fixing bolt. The fixing nut is connected to the inner sidewall of the housing, and the fixing bolt passes through the rear sidewall of the mounting base and the housing in the front-rear direction and is threadedly connected to the fixing nut.

[0014] In some embodiments, the mounting base has a through hole extending along the front-back direction. The diameter of the through hole gradually increases from one end to the other. A fixing nut is provided through the through hole. The mounting base can be moved to the small diameter end where the fixing nut enters the through hole to lock the mounting base, or moved to the large diameter end where the fixing nut enters the through hole to disengage from the fixing nut.

[0015] In one possible implementation, the lower outer circumference of the rake bar is threaded with rake claws.

[0016] The grape vine rake device for the shredder provided in this embodiment, compared with the prior art, forcibly controls and guides the grape vines to the shredding mechanism through physical means, ensuring that the grape vines are effectively grasped and fed in. This significantly reduces the number of long grape vines remaining on the field surface, improves the thoroughness of a single shredding operation, thereby avoiding secondary manual cleaning or re-shredding, saving operation time and production costs, and improving overall operation efficiency.

[0022] The forward and backward directions mentioned throughout the text are Figure 1 The direction indicated by the middle arrow.

[0023] Please see Figures 1 to 6 The present invention provides a grape vine raking device for a crusher. The crusher includes a tractor 1, a crushing mechanism 2 located at the rear of the tractor 1, and a cover 3 covering the crushing mechanism 2. The grape vine raking device comprises a mounting base 10 and several raking components 30. The mounting base 10 is located on the rear side wall of the cover 3, and a mounting rod 20 extending in a left-right direction is provided on the rear side of the mounting base 10. Several raking components 30 are spaced apart along the axial direction of the mounting rod 20. Each raking component 30 includes a sliding sleeve 31 slidably fitted around the outer periphery of the mounting rod 20 and a raking rod 32 located at the bottom of the sliding sleeve 31. The sliding sleeve 31 is locked by a locking member 40, and the raking rod 32 extends downward for hooking grape vines.

[0024] This application embodiment provides a grape vine rake device for a crusher. In actual use, the rake device is fixed to the rear side wall of the housing 3 via a mounting base 10. A mounting rod 20 is horizontally arranged behind the housing 3. Multiple rake components 30 are slidably fitted onto the mounting rod 20 via sliding sleeves 31. The operator can move these rake components 30 to appropriate left and right positions according to the accumulation of vines in the field and the width of the crusher. After the position is determined, a locking member 40 is used to fix the sliding sleeve 31 to the mounting rod 20. Finally, the rake rods 32 are extended downwards, with their bottoms below the inlet of the crushing mechanism 2. When the tractor 1 pulls the crusher forward, these rake rods 32 will actively hook and rake the tangled grape vines on the ground during the machine's movement. After accumulating to a certain extent, they will automatically enter the inlet of the crushing mechanism 2.

[0025] This device fundamentally solves the problem of grapevines being bounced off or dragged out. By physically controlling and guiding the grapevines to the crushing mechanism 2, it ensures that the grapevines are effectively grasped and fed in. This significantly reduces the number of long grapevines remaining on the field surface, improves the thoroughness of a single crushing operation, thereby avoiding secondary manual cleaning or re-crushing, saving operating time and production costs, and improving overall operating efficiency.

[0026] The grape vine rake device for the crusher provided in this embodiment, compared with the prior art, forcibly controls and guides the grape vines to the crushing mechanism 2 through physical means, ensuring that the grape vines are effectively grasped and fed in. This significantly reduces the number of long grape vines remaining on the field surface, improves the thoroughness of a single crushing operation, thereby avoiding secondary manual cleaning or re-crushing, saving operating time and production costs, and improving overall operating efficiency.

[0027] In one possible implementation, the aforementioned mounting rod 20 adopts the following... Figure 4 and Figure 5 The structure shown is described in the following document. Figure 4 and Figure 5 The mounting rod 20 has a first locking hole 21 extending through it in the front-back direction. Several first locking holes 21 are spaced apart along the axial direction of the mounting rod 20. The sliding sleeve 31 has a second locking hole 311 extending through it in the front-back direction. The locking member 40 extends through the second locking hole 311 and one of the first locking holes 21 in the front-back direction.

[0028] Specifically, when the position of a certain rake component 30 needs to be adjusted, the operator first removes the locking component 40, separating the second locking hole 311 of the sliding sleeve 31 from the first locking hole 21 on the mounting rod 20. Then, the sliding sleeve 31 is slid along the axial direction of the mounting rod 20 to the target position. At this time, the multiple first locking holes 21 pre-set on the mounting rod 20 provide multiple fixed positioning points. Aligning the second locking hole 311 on the sliding sleeve 31 with the first locking hole 21 at the target position, and re-inserting the locking component 40, the fixing is completed.

[0029] It provides a simple and reliable positioning and locking mechanism. Multiple first locking holes 21 allow for clear scales in the spacing adjustment of the rake parts 30, ensuring precise and secure positioning. This prevents the rake parts 30 from shifting due to vibration during operation, thus guaranteeing the stability of the rake effect.

[0030] In some embodiments, see Figure 3 and Figure 5 The first locking hole 21 is elliptical in shape, and the locking member 40 is elliptical in shape to match the first locking hole 21.

[0031] Specifically, when the locking member 40 (designed as an elliptical cylinder) is inserted into the first locking hole 21 and the second locking hole 311, which are also elliptical holes, the locking member 40 is in a state where its long axis is aligned with the long axis of the hole, which avoids the rotation and jumping of the locking member 40 and reduces the risk of it coming off.

[0032] In some embodiments, see Figure 2 and Figure 3 A limiting member 50 is axially provided on the locking member 40. The front end of the limiting member 50 is provided with an elliptical limiting piece 51. The limiting piece 51 is adapted to the first locking hole 21. The limiting member 50 can drive the limiting piece 51 to rotate and make the limiting piece 51 contact and cooperate with the side wall of the mounting rod 20 to restrict the locking member 40 from disengaging from the first locking hole 21.

[0033] Specifically, after inserting the elliptical locking member 40, the operator rotates the limiting member 50. The elliptical limiting piece 51 at the front end of the limiting member 50 rotates accordingly. When the major axis of the limiting piece 51 is aligned with the minor axis of the locking member 40, the locking member 40 is prevented from disengaging from the first locking hole 21.

[0034] In some embodiments, see Figure 2 The rear end of the locking member 40 is provided with a limiting platform 41 that protrudes outward and is used to contact and engage with the rear side wall of the sliding sleeve 31.

[0035] Specifically, when the locking member 40 is inserted from back to front into the locking hole of the sliding sleeve 31 and the mounting rod 20, the limiting platform 41 at its rear end will contact the rear side wall of the sliding sleeve 31.

[0036] The limiting stage 41 serves as an axial positioning element. It defines the final insertion position of the locking element 40, preventing the operator from over-inserting it.

[0037] In some embodiments, see Figure 2 The rear end of the limiting member 50 is provided with a mounting platform 52 that protrudes outward.

[0038] Specifically, the mounting platform 52 at the rear end of the limiting member 50 provides an operator with a structure that facilitates the application of force. The mounting platform 52 makes it easy to rotate the limiting member 50 directly by hand without the need for other tools.

[0039] In some embodiments, see Figure 1 and Figure 2 The outer periphery of the limiting member 50 is fitted with an elastic member 60, which is located between the locking member 40 and the mounting platform 52 and is used to elastically push the mounting platform 52.

[0040] Specifically, the elastic element 60 (such as a compression spring) fitted onto the limiting member 50 is pre-pressed between the locking member 40 and the mounting platform 52. The elastic force of the elastic element 60 continuously pushes the mounting platform 52 backward, thereby ensuring that the front limiting piece 51 always has a tendency to move backward through the limiting member 50, thus maintaining a pressed state with the end face of the locking member 40 and preventing the limiting piece 51, which has been adjusted in position, from rotating automatically.

[0041] In one possible implementation, the aforementioned mounting base 10 adopts the following... Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The mounting base 10 is connected to the cover 3 via a fastener 70. The fastener 70 includes a fixing nut 71 and a fixing bolt 72. The fixing nut 71 is connected to the inner side wall of the cover 3. The fixing bolt 72 passes through the mounting base 10 and the rear side wall of the cover 3 in the front-back direction and is threadedly connected to the fixing nut 71.

[0042] Specifically, during installation, first weld or fasten the fixing nut 71 to the inner wall of the cover 3. Then, place the mounting base 10 against the outer side of the cover 3, so that the fixing bolt 72 passes through the holes on the mounting base 10 and the holes on the wall of the cover 3 from back to front, and finally tightens it with the fixing nut 71 on the inner side.

[0043] This connection method is very robust and reliable. The connection between the fixing bolt 72 and the fixing nut 71 can withstand significant vibration and load. Furthermore, it allows for easy installation and disassembly from the outside, facilitating maintenance.

[0044] In some embodiments, see Figure 6 The mounting base 10 has a through hole 11 extending along the front-back direction. The diameter of the through hole 11 gradually increases from one end to the other. The fixing nut 71 is installed through the through hole 11. The mounting base 10 can be moved to the small diameter end of the through hole 11 where the fixing nut 71 enters to lock the mounting base 10, or moved to the large diameter end of the through hole 11 where the fixing nut 71 enters to disengage from the fixing nut 71.

[0045] Specifically, the through hole 11 on the mounting base 10 is designed in a keyhole shape (smaller at one end and larger at the other). To secure the mounting base 10, first place its larger diameter end onto the fixing nut 71, then move the mounting base 10 so that the fixing nut 71 slides into the smaller diameter end of the through hole 11. Then rotate and tighten the fixing nut 71 to lock the mounting base 10. To disassemble, move the mounting base 10 in the reverse direction until the fixing nut 71 reaches the larger diameter end, then remove the mounting base 10. This allows for quick installation and disassembly of the entire rake-pulling device.

[0046] In one possible implementation, the aforementioned rake 32 adopts the following... Figure 1 and Figure 2The structure shown is described in the following document. Figure 1 and Figure 2 The lower outer circumference of the rake rod 32 is threaded with rake claws 80.

[0047] Specifically, the lower end of the rake rod 32 is machined with external threads, and the rake claw 80 (whose shape can be designed as hook-shaped, tooth-shaped, etc.) is machined with corresponding internal threads. By rotating the rake claw 80, its axial position relative to the rake rod 32 can be adjusted, or it can be unscrewed and replaced directly.

[0048] The rake claw 80 is the part that comes into direct contact with the grapevines and is most prone to wear. The threaded connection makes the rake claw 80 a replaceable wear part. When the rake claw 80 is severely worn, only the rake claw 80 needs to be replaced, instead of replacing the entire rake handle 32, which significantly reduces maintenance costs.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
