Description
Technical Field
[0001] This utility model relates to the technical field of leaf crushing devices, and more specifically, to a leaf crusher. Background Technology
[0002] A leaf shredder is a device used to crush leaves. Currently, leaf shredders on the market mainly consist of a leaf shredder main unit, a material cylinder, a hopper, and a support frame. The leaf shredder main unit is fixed to the upper end of the support frame, the lower end of the material cylinder is fixed to the upper end of the leaf shredder main unit, and the hopper is assembled on the inner side of the upper part of the material cylinder. When leaves are guided by the hopper and enter the material cylinder, the leaves in the material cylinder fall into the leaf shredder main unit, where they are then crushed and discharged from the main unit from top to bottom. However, in the above-mentioned leaf shredder structure, since the leaf shredder main unit, the support frame, and the material cylinder are all in a fixed state, there are disadvantages in packaging and transporting the leaf shredder, such as large packaging volume, high packaging cost, and high transportation cost. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a leaf shredder that has the advantages of small packaging volume and low packaging cost when packaged and transported, as well as convenient transportation and low transportation cost.
[0004] This utility model provides a leaf shredder, including a leaf shredder main unit, a material cylinder, a hopper, and a support frame; the leaf shredder main unit is detachably connected to the upper end of the support frame, the lower end of the material cylinder is detachably connected to the upper end of the leaf shredder main unit, and the hopper is detachably connected to the inner side of the upper part of the material cylinder; the inner cavity of the material cylinder is larger than the outer diameter of the leaf shredder main unit; when the leaf shredder main unit is separated from the support frame, the material cylinder is separated from the leaf shredder main unit, and the hopper is separated from the material cylinder, the leaf shredder main unit is placed into the inner cavity of the material cylinder to reduce the packaging volume of the leaf shredder.
[0005] By adopting the above-described structure, this utility model allows for the separation of the leaf crusher from the support frame, the separation of the material cylinder from the leaf crusher, and the separation of the hopper from the material cylinder during packaging and transportation. The leaf crusher can be placed inside the material cylinder, and then the hopper can be placed over the leaf crusher located in the material cylinder. This reduces the packaging volume and cost of the leaf crusher, as well as the transportation cost.
[0006] In one possible implementation, the left and right outer walls of the leaf crusher are provided with blind insertion holes with open bottom ends. The bracket includes a support base and two support tubes. The lower ends of the two support tubes are connected to the support base, and the upper ends of the two support tubes are respectively inserted into one of the blind insertion holes and fastened to the leaf crusher with screws. With this structure, after the upper ends of the two support tubes are respectively inserted into one of the blind insertion holes and fastened to the leaf crusher with screws, the leaf crusher can be reliably connected to the upper end of the bracket. When the upper ends of the two support tubes are disengaged from the blind insertion holes, the leaf crusher can be separated from the bracket.
[0007] In one possible implementation, the support base includes a U-shaped support section, which is horizontally positioned with its opening facing the rear of the leaf crusher. Both ends of the support section are provided with upwardly bent sleeve sections. The lower ends of two support tubes are respectively inserted from top to bottom into one of the sleeve sections and fastened to the sleeve section by a hand-tightening bolt threaded to the side wall of the sleeve section. With this structure, the two support tubes can be separated from the support base. That is, when the hand-tightening bolt is released from the fastening of the support tubes and sleeve sections, the lower ends of the support tubes can be pulled out from the sleeve sections, thereby realizing the separation of the support tubes from the support base. After the support tubes are separated from the support base, the packaging volume of the leaf crusher can be further reduced, and the packaging cost can be lowered.
[0008] In one possible implementation, the leaf crusher also includes a rotating shaft and two rollers; the rotating shaft is transversely and rotatably inserted through two sleeve sections, and the two rollers are respectively fixed to one end of the rotating shaft; two support blocks are fixed at the bottom of the front edge of the support section, which are distributed at left and right intervals; with this structure, when it is necessary to move the leaf crusher, it can be turned from front to back, so that the two rollers are supported on the ground and the two support blocks are lifted off the ground. At this time, the leaf crusher can be moved on the ground by relying on the two rollers, which has the advantage of convenient leaf crusher movement; when the leaf crusher is moved to the target position, the leaf crusher can be released and the support blocks can be supported on the ground again.
[0009] In one possible implementation, the lower end of the feed cylinder is inserted into the upper end of the leaf crusher. A first annular step is provided on the inner side of the upper end of the leaf crusher, and the lower end of the feed cylinder abuts against the first annular step. A pair of fastening blocks are provided on the outer wall of the feed cylinder, and fasteners corresponding to the fastening blocks are connected to the outer wall of the leaf crusher. Each fastener engages with the fastening block on the corresponding side to lock the feed cylinder and the leaf crusher. With this structure, after the lower end of the feed cylinder is inserted into the upper end of the leaf crusher and abuts against the first annular step, each fastener can be operated to engage with the fastening block at the corresponding position, thereby easily locking the feed cylinder and the leaf crusher. When each fastener disengages from the fastening block and the lower end of the feed cylinder is removed from the leaf crusher, the feed cylinder and the leaf crusher can be easily separated.
[0010] In one possible implementation, a second annular step is provided on the inner side of the upper part of the barrel, and the outer edge of the hopper is supported on the second annular step. Several circumferentially spaced buckles are also provided on the side wall of the upper part of the barrel, and the buckles abut against the upper end of the outer edge of the hopper to fasten the hopper to the second annular step. With this structure, after the hopper is assembled into the barrel, the outer edge of the hopper can be supported on the second annular step, and the buckles can abut against the upper end of the outer edge of the hopper to fasten the hopper to the second annular step, that is, the hopper can be reliably and conveniently assembled on the inner side of the upper part of the barrel. When the hopper is pulled upward to disengage the outer edge of the hopper from the buckles (the hopper is made of plastic material and has a certain degree of deformability), the hopper can be easily removed from the barrel.
[0011] In one possible implementation, the outer edge of the hopper is provided with a downwardly folded annular flange, and the bottom of the second annular step is provided with an annular slot, into which the annular flange is inserted. With this structure, after the hopper is assembled into the barrel, the annular flange can be inserted into the annular slot, thereby achieving the limiting and positioning function of the hopper and the barrel, which in turn facilitates the assembly of the hopper and the barrel and improves the reliability of the hopper and the barrel after assembly, that is, it can further improve the reliability of the hopper being fastened to the second annular step by the inverted buckle.
[0012] In one possible implementation, an annular groove is provided on the inner wall of the cylinder located radially inside the second annular step, and an annular protrusion is provided on the bottom surface of the hopper, with the annular protrusion supported on the inner bottom of the annular groove. By adopting this structure, the support strength of the hopper can be further improved after the annular protrusion is supported on the inner bottom of the annular groove, so as to avoid the hopper from collapsing downward.
