Abstract
The utility model discloses a force-increasing type manual straw breaker which can effectively reduce labor intensity in the manual straw breaking process. The straw breaker structurally comprises a lever, an upper connection rod, a middle connection rod, a lower connection rod, a press rod, an upper cutter edge, a lower cutter edge, a frame, hinge bolts and fixed bolts. The lever, the middle connection rod and the frame form a first-stage lever force-increasing mechanism and are movably connected through the high bolts. The upper connection rod, the middle connection rod, the lower connection rod and the frame form a second hing rod force-increasing mechanism. The upper end of the press rod is movably hinged with the lower connection rod through a hinge bolt, the lower end of the press rod is connected with the upper cutter edge and is fixed through the fixed bolts, and the lower cutter edge is installed on the frame corresponding to the upper cutter edge and is fixed by the fixed bolts. The force-increasing type manual straw breaker adopts the secondary force-increasing mechanism, and greatly reduces driving force in the straw breaking process. Due to the fact that a base plate on the lower portion of the frame is larger, the straw breaker is prevented from being overturned. Users do not need to bend in the straw breaking process due to the fact that the frame is high.
Description
Technical field
The utility model relates to the machining tool of herbage stalk, particularly the manual hay cutter of a kind of boosting-type.
Background technology
Force-increasing mechanism chopper of lever hand hay cutter grass is generally used in existing rural area, pastoral area, cut up with a hay cutter in careless process, and personnel's labour intensity is high, and the work of need bending over just can fulfil assignment when working.
The utility model content
The utility model provides a kind of boosting-type manual hay cutter, effectively alleviates the labour intensity of the careless process of manual hand hay cutter.
The structure of the manual hay cutter of boosting-type that the utility model provides comprises: lever, upper connecting rod, middle connecting rod, lower link, depression bar, upper knife edge, lower blade, frame, hinge bolt and set bolt, the one-level lever boosting mechanism that forms of lever, middle connecting rod and frame wherein, they are flexibly connected by hinge bolt; Wherein go up the force-increasing mechanism of the secondary toggle of connecting rod, middle connecting rod, lower link and frame composition, the depression bar upper end is by hinge bolt and lower link active link, and the lower end connects blade, fixes with set bolt, the corresponding upper knife edge of lower blade is arranged on frame, fixes with set bolt.
Described depression bar is " T " character form structure, and top has groove and circular hole, embeds lower link and hinge bolt is installed, and the bottom has 5 circular holes, installs blade by set bolt.
The cutting edge of described upper knife edge and lower blade is curved, prevents blade middle part Fast Wearing, extends the service life of blade.
The riser in described frame the place ahead is provided with the square hole as charging aperture, and the shelf position bottom that lower blade is installed is discharging opening.
The utility model is compared with existing similar tools, and its beneficial effect is embodied in:
The manual hay cutter of boosting-type adopts the secondary force-increasing mechanism, the driving force when having alleviated greatly the hand hay cutter grass, and the base plate of frame lower is larger, can prevent that hay cutter from tumbling; Frame is higher, the work of need not bending over during the hand hay cutter grass.
