Orchard Hand-Push Type Multi-Purpose Tree Shredder for Wet and Dry Branches and Twigs

Furthermore, the crushing blade set includes a driving blade set and a driven blade set. The driving blade set and the driven blade set consist of a driving gear, a driven gear, a rotating shaft, a crushing blade holder connected to the rotating shaft, and crushing blades attached to the crushing blade holder.

Additionally, the crushing blade holder is connected to the rotating shaft via a flat key, while the crushing blades are fastened to the crushing blade holder using bolts. Fibrous materials such as branches, wood, and bark are increasingly valued for their utility. After crushing, they can be used as raw materials for mushroom cultivation. However, there is a scarcity of specialized crushing equipment designed for these highly "tough" materials on the market. Even when such equipment exists, the durability of the blades is often poor. To ensure robustness, the sharpness at high speeds is frequently compromised. Using integrated high-speed steel blades would be too costly. Most blade designs are highly specialized. For instance, edge-trimming and chamfering electric planer blades consist of blades, pressure plates, screws, and a blade holder. The blade holder is composed of two parts: one featuring a dual-cylinder structure with parallel cutting chord surfaces, and the other with a frustum shape also having parallel cutting chord surfaces, organically connected to form a combined blade holder with a polyline generatrix. This design processes complete finger shapes, where the distance between teeth on the same slot is twice the finger pitch of the workpiece, and teeth on adjacent slots are staggered circumferentially. Blade slots are milled into the tooth profile, and cemented carbide blades are welded onto them.
