Description

Technical Field

[0001] This utility model belongs to the technical field of branch shredders, and specifically relates to a branch shredder that facilitates the crushing of forked branches. Background Technology

[0002] Branch shredders are mainly used in the landscaping industry to process pruned branches. The working principle of a branch shredder is based on the high-speed rotation of blades to cut and shred the branches.

[0003] Currently, Chinese patent publication number CN221602203U, published on August 27, 2024, discloses a wood chipper that facilitates the placement of a pressing plate, comprising a movable support, a collection box, a wood chipper head, a pressing plate, and elastic buckles. The wood chipper head is fixedly connected to the movable support, the collection box is located at the bottom of the wood chipper head, the pressing plate is detachably connected to the wood chipper head, and two elastic buckles are provided, which are symmetrically and detachably connected to both sides of the movable support. The pressing plate is slidably connected to the elastic buckles. Each elastic buckle includes a clamping arm, a connecting plate, and a locking tooth. The connecting plate is fixedly connected to the clamping arm, and the locking tooth is located on the connecting plate.

[0004] The existing technology uses a long, narrow feeding trough at the top of the shredder head to feed tree branches. However, in order to prevent excessively thick branches from entering the shredder head and causing damage, the width of the feeding trough needs to be within a specified range. This makes it difficult for some forked branches to enter the feeding trough. Operators need to chop off the branches in advance before feeding the branches into the trough, which makes the shredding of forked branches more troublesome, time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a branch shredder that facilitates the crushing of forked branches, which is beneficial for crushing forked branches.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a branch shredder that facilitates the shredding of forked branches, comprising a movable support, a head with an internal motor and blades, a collection box located on the lower side of the head, and a feeding frame disposed at the upper end of the head. The feeding frame comprises a first frame on the upper side and a second frame on the lower side. A first feeding hole is provided in the middle of the first frame, and a second feeding hole corresponding to the first feeding hole is provided in the middle of the second frame. Two first protrusions are provided on the side of the first feeding hole, and the distance between the two first protrusions is adapted to the cross-sectional diameter of the branch that meets the shredding conditions. Two second protrusions corresponding to the positions of the first protrusions are provided on the side of the second feeding hole. A forked opening for the branch to be embedded is formed between the two first protrusions. The lower side of the first protrusion is hollowed out and the upper side of the second protrusion is hollowed out. A reinforcing frame with an "I"-shaped cross-section is provided inside the second protrusion for embedding in the first protrusion.

[0007] A further feature of this invention is that: a feed inlet for tree branches is provided at the upper end of the machine head; an opening groove for the second frame to be embedded is provided on the periphery of the upper end of the feed inlet; a positioning slot is provided on the inner wall of one side of the opening groove; and a vertical insert plate embedded in the positioning slot is provided on the side of the second frame.

[0008] A further feature of this invention is that the upper surface of the first protrusion is an arc shape that curves toward the inside of the first feeding hole.

[0009] A further feature of this invention is that an arc-shaped guide groove is provided at the end of the first feeding hole.

[0010] A further feature of this invention is that: the first frame body is provided with a plurality of connecting sleeves located around the first feeding hole; the upper end face of the machine head is provided with a plurality of threaded holes corresponding to the positions of the plurality of connecting sleeves; and the first frame body is provided with connecting bolts that pass through the connecting sleeves and are threaded into the threaded holes.

[0011] A further feature of this invention is that a handle is provided on the side of the first frame.

[0012] A further feature of this invention is that a guide slope is provided on the side of the upper end of the reinforced frame.

[0013] A further feature of this invention is that the movable support is provided with an inclined support arm, and both ends of the inclined support arm are provided with elastic buckles with a "C" shaped cross section for engaging with the movable support.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. The feeding machine includes a first frame and a second frame. The first feeding hole has two first protrusions on its side. The distance between the two first protrusions is adapted to the cross-sectional diameter of the branch that meets the crushing conditions, thereby preventing excessively thick branches from entering the first feeding hole. At the same time, since a fork is formed between the two first protrusions for the branch to embed, the existence of the fork facilitates the passage of the branch branches, which ultimately helps to crush the forked branches.

[0016] The design utilizes the lower side of the first protrusion and the upper side of the second protrusion to save materials. At the same time, the reinforcing frame with an "I"-shaped cross-section is set inside the second protrusion. The reinforcing frame can be embedded in the first protrusion to reinforce the structure and reduce the possibility of deformation after the first protrusion hits the tree branches. Furthermore, when the surface of the first protrusion is damaged and needs to be replaced, the first frame can be removed from the second frame and replaced separately without replacing the entire feeding frame.

[0017] 2. The second frame can be inserted into the opening slot at the upper end of the feed inlet, thereby limiting the position of the second frame in the feed inlet. At the same time, the vertical insert plate on the side of the second frame can be inserted into the positioning slot, thereby positioning the installation position of the second frame in the opening slot and preventing the second frame from being installed backwards in the positioning slot.

[0018] 3. The upper surface of the first protrusion is curved in an arc shape towards the first feeding hole. The arc-shaped surface can guide the branches entering the first feeding hole, which is conducive to the smooth entry of the branches into the first feeding hole.

[0019] 4. The arc-shaped guide groove at the end of the first feeding hole can guide the tree branch embedded at the end of the first feeding hole.

[0020] 5. When the first frame is installed on the upper end of the machine head, the connecting bolts are threaded through the connecting sleeve of the first frame and then threaded into the threaded hole on the upper end face of the machine head, thus realizing the detachable connection of the first frame on the upper end of the machine head.

[0021] 6. The first frame is also equipped with a handle on the side, which makes it easy for the operator to hold and thus facilitates feeding materials;

[0022] 7. The guide ramp opened on the side of the upper end of the reinforcing frame can play a guiding role, which is conducive to the smooth embedding of the reinforcing frame into the first boss.

[0023] 8. The inclined support arm installed inside the mobile support is used, and the end of the inclined support arm is attached to the mobile support by an elastic buckle. At this time, the inclined support arm can strengthen the structure of the mobile support and help stabilize the mobile support. Attached Figure Description
