Shear of backpack-type mulberry branch cutting machine

Abstract

The invention discloses a shear of a backpack-type mulberry branch cutting machine. The shear of the backpack-type mulberry branch cutting machine solves the problem that an existing mulberry branch cutting machine is inconvenient to operate. According to the technical measure, the shear of the backpack-type mulberry branch cutting machine comprises a shear body, two blades of the shear body are hinged to the front end portion of a connecting rod through a pivot in a cross mode, the knife edge parts of the blades extend out towards the front end portion of the connecting rod, handles of the blades extend to the rear end portion of the connecting rod, and cutting edges of the knife edge parts of the two blades are opposite. The shear of the backpack-type mulberry branch cutting machine is characterized in that a sliding block is arranged on the connecting rod in a clearance mode; the sliding block and the handles of the two blades are movably connected through connection pieces; a reset spring used for enabling the shear to be opened is arranged between the sliding block and the connecting rod; an inhaul cable used for enabling the shear to be closed is connected with the sliding block; the inhaul cable extends within the width range of the connecting rod.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a backpack-type mulberry branch cutting machine for cutting mulberry branches, and more particularly to the shears on the cutting machine. Background technique [0002] In the process of mulberry planting, reasonable cutting of mulberry branches can effectively promote the growth of mulberry leaves. Therefore, the branches of mulberry trees are cut every year. Due to the difference in climate, there are winter cutting, spring cutting and summer cutting. At present, farmers mainly plant mulberry and sericulture, and only cut stalks once a year. Large-scale machinery is not suitable, and sliver cutting operations are mainly done by hand. This operation method is slow, labor-intensive, and very laborious. For effectively alleviating the labor intensity when cutting mulberry strips, some implements have also occurred now. Because mulberry tree cutting needs to be operated in the field, fr...

Problems solved by technology

The energy conversion rate of the above-mentioned equipment is low, the fuel utilization rate is low, the weight is too large to carry, and the cost of high-performance batteries is relatively high, which is not conducive to the popularization of this equipment.

[0003] A Chinese invention patent (patent number: 201010573932.7) discloses a backpack-type mulberry branch cutting machine, which solves the problems of complex structure and inconvenient operation of the existing mulberry branch cutting equipment. The technical measures taken: a backpack Type mulberry branch felling machine, including a moving knife and a fixed knife, the moving knife and the fixed knife are cross-hinged together, there is a return spring between the moving knife and the fixed knife, the handle of the fixed knife is fixed with the support rod, and can be moved on the support rod. There is a guide wheel for rotation; the handle of the moving knife is connected with the cable, and the cable bypasses the guide wheel to connect with the power machine; a pulling mechanism is arranged between the handle of the moving knife and the power machine, and the pulling Connected, after operating the trigger mechanism, the tension of the cable will change

[0004] In this kind of cutting machine, since the cable is connected with the handle of the moving knife, and when the cable is in a relaxed state (in the actual operation process, before the scissors and branches are clamped, the cable is in a relaxed state), the dynamic The outer end of the handle of the knife is equivalent to an open structure, but in the mulberry garden, the branches are relatively dense, and it is inevitable that the outer end of the handle of the moving knife will not catch the upright branches. Seriously affect the cutting speed of branches

In addition, since only the moving knife is in action, when cutting the branches, the fixed knife only supports the branches, and the force on the moving knife is relatively large, which will affect the balance of the scissors, and it is inconvenient to adjust the scissors. to hold
