Description

Technical Field

[0001] This utility model relates to the field of shredding equipment technology, specifically a mulberry leaf and branch shredding device. Background Technology

[0002] A typical wood chipper has a shredding cylinder that runs through both ends. The upper opening of the cylinder is the feed inlet, and the lower opening is the discharge outlet. A toothed blade is installed inside the cylinder, and a cutter plate is mounted on one side wall of the machine. Wood stalks or similar materials are fed into the cylinder through the feed inlet at the top, between the toothed blade and the cutter plate. The rotating toothed blade cuts and shreds the stalks, and the shreds leak out from the discharge outlet at the bottom of the cylinder. However, since wood stalks are generally cylindrical, they are prone to misalignment when the blade contacts them, especially when there is only one toothed blade or the blade is small. If the stalk deviates or becomes distorted, it can easily cause blockages inside, significantly limiting subsequent stalk shredding operations.

[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a mulberry leaf and twig chopping device, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a mulberry leaf and twig chopping device, including a branch breaking frame, a feeding trough formed on the upper side of the branch breaking frame, a cutting mechanism provided on the inner side of the frame, a stalk crushing mechanism provided between the cutting mechanism and the feeding trough, the stalk crushing mechanism including two adjacent crushing rollers, one of the crushing rollers being driven to rotate by an outer motor, a limiting ring groove horizontally spaced on the crushing roller, and crushing blocks fixed circumferentially within the limiting ring groove.

[0008] Preferably, multiple baffles are fixed at the inlet of the feed trough, and the spacing between two adjacent baffles corresponds one-to-one with the size and position of the limiting ring groove.

[0009] Preferably, the cutting mechanism includes a plurality of cutting wheels spaced apart along the stalk conduction path, wherein the cutting edge of the lower cutting wheel cuts the stalk deeper than the cutting edge of the upper cutting wheel.

[0010] Preferably, the upper and lower cutting wheels are cutting wheel one and cutting wheel two, respectively. The branch breaking frame is connected to the support at the cutting wheel. Multiple cutting wheels are provided at the same height and are pivotally connected to the support through a rotating shaft and synchronously driven by a motor.

[0011] Preferably, the upward orthogonal projection of the cutting wheel is located within the limiting ring groove.

[0012] Preferably, the inner end face of the support on the opposite side of the cutting wheel and the inner end edge of the rolling wheel are on the same longitudinal plane, and the support serves as a stable support position for cutting the support rod. A gap is left between the two supports to allow the support rods cut into small pieces to fall out.

[0013] Preferably, the branch-breaking frame is provided with inward-facing cutting blades directly below the two crushing rollers, and a fragment outlet is provided on the opposite outer side of each blade.

[0014] (III) Beneficial Effects

[0015] After adopting the above technical solution, the present invention has the following advantages compared with the prior art: The mulberry leaf and twig chopping device of the present invention has a twig crushing mechanism between the cutting mechanism and the feeding trough. The twig crushing mechanism includes two adjacent crushing wheels. The crushing wheels are horizontally spaced with limiting ring grooves. Crushing blocks are fixed circumferentially in the limiting ring grooves. The limiting ring grooves are used to limit the position of the twigs. After rotating a small angle, the crushing blocks can flatten the twigs placed in the limiting ring grooves to a certain extent. During the process of inwardly retracting the twigs, they can be basically clamped by the crushing blocks of the crushing wheels on both sides. At the same time, the limiting ring grooves can also play a lateral limiting force to avoid uneven horizontal force and distortion of the twigs, and provide a stable limiting force when the cutting wheel cuts.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-2As shown: Mulberry leaf and stalk chopping device includes a branch breaking frame 1, a feeding trough 2 formed on the upper side of the branch breaking frame 1, a cutting mechanism is provided on the inner side of the branch breaking frame 1, and a stalk crushing mechanism is provided between the cutting mechanism and the feeding trough 2. The stalk crushing mechanism crushes the stalk, flattens it from a cylindrical shape to facilitate cutting, and at the same time forms a clamping limit while squeezing the mulberry leaf stalk inward.

[0022] The cutting mechanism includes multiple cutting wheels spaced apart along the branch conduction path. The cutting edge of the lower cutting wheel cuts the branch more deeply than that of the upper cutting wheel, thus achieving layer-by-layer cutting until it is cut into pieces. This embodiment only shows the upper and lower cutting wheels 7 and 8. The branch breaking frame 1 is located at the cutting wheel as a support 13, and the cutting wheel is pivotally connected to the support 13 via a rotating shaft and driven by a motor 9.

[0023] See appendix Figure 3 As shown, the support rod compaction mechanism includes two adjacent compaction rollers 4, one of which is driven to rotate by an outer motor 9. A limiting ring groove 10 is horizontally spaced on the compaction roller 4, and compaction blocks 11 are fixedly fixed circumferentially within the limiting ring groove 10.

[0024] The limiting groove 10 is used to limit the insertion of the branch, and after rotating a small angle, the crushing block 11 can flatten the branch placed in the limiting groove 10 to a certain extent. During the process of pulling the branch inward, it can be basically clamped by the crushing blocks 11 of the crushing wheels 4 on both sides. At the same time, the limiting groove 10 can also play a lateral limiting force, thereby providing a stable limiting force when the cutting wheel cuts.

[0025] Furthermore, multiple baffles 3 are fixed at the inlet of the feed trough 2. The spacing between two adjacent baffles 3 corresponds one-to-one with the size and position of the limiting ring groove 10, so that the inserted support rod can be stably inserted and shredded. At the same time, multiple cutting wheels are provided at the same height on the lower side, and the upward projection of the cutting wheels corresponds to the limiting ring groove 10.

[0026] Secondly, the inner end face of the support 13 on the opposite side of the cutting wheel and the inner end edge of the rolling wheel 4 are on the same longitudinal plane (see Appendix). Figure 2 (Diagram showing the position indicated by the dotted line) This allows the support 13 to serve as a stable support position for the cutting of the support rod. A gap is left between the two supports 13 to allow the support rod pieces cut into small packages to fall out.

[0027] Furthermore, the branch-breaking frame 1 is provided with inward-facing cutting blades 12 directly below the two rolling rollers 4, which are used to cut off the remaining branches on the support. At the same time, a fragment outlet 6 is provided on the opposite outer side to discharge the cut branches out of the branch-breaking frame 1.

[0028] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
