The output shaft of the motor is connected with the keyway of the cam, and drives the cam to rotate counterclockwise. The cam drives the roller to rotate, and the roller drives the ejector rod to move up and down regularly. The frame is fixed in the two bearings at the two ends of the mounting plate. One end of the tool frame is connected to the tool bar through an angle-adjustable fixing screw. One end of the return spring is connected, and the other end of the return spring is fixed on the fixed mounting plate. The utility model has the advantages of simple structure, short working stroke and low energy consumption, which can effectively improve production efficiency, reduce labor intensity, and reduce energy consumption and production cost.

Description

Semi-rotary cutting device for seedling grafting machine

technical field

The utility model relates to a semi-rotary cutting device for a seedling grafting machine.

Background technique

Grafting machine technology is a high-tech that has emerged in the world in recent years, integrating machinery, automatic control and horticultural technology. Its cutting device is an important part of the seedling grafting machine. The design of the cutting device directly affects the efficiency of grafting. , Survival rate and quality of seedling grafting machine. Research on the Cutting Mechanism of Grafting Machine Japan Kobayashi Ken, Yoshihiro Nishiura, etc. researched and reported on the vegetable cutting mechanism in 1996 and 1999 respectively; they used hydraulic or pneumatic shearing type, the structure of this kind of cutting mechanism is complex, and the power system requires high precision , the production cost is very high.

Utility model content

The purpose of the utility model is to provide a fully mechanical semi-rotary cutting device for seedling grafting machines with simple structure, low production cost, short working stroke, high working efficiency and low energy consumption.

The purpose of this utility model is achieved through the following technical solutions: the output shaft of the motor is connected with the keyway of the cam, and drives the cam to rotate counterclockwise, the cam drives the roller to rotate, and the roller drives the ejector rod on the roller to move up and down, and the upper end of the ejector rod It is connected with a sliding block that can slide on the knife holder, and the knife holder is fixed in the two bearings at the two ends of the mounting plate. One end of the knife holder is connected with the knife rod through an adjustable fixing screw to cut two pieces of sticky wood and ear wood. The blades are respectively fixed on the two ends of the cutter bar, and the cutter holder is also connected with one end of the return spring, and the other end of the return spring is fixed on the fixed mounting plate.

The utility model has the advantages of simple structure, short working stroke and low energy consumption, which can effectively improve production efficiency, reduce labor intensity, and reduce energy consumption and production cost.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The output shaft of the motor 13 installed on the frame 8 is connected with the keyway of the cam 10, and drives the cam to rotate counterclockwise. The cam drives the roller 9 at the lower end of the ejector rod 7 and drives the ejector rod to move up and down regularly. The slider 11 that can slide on the knife rest 12 is connected, and the knife rest 12 is fixed in the two bearings 6 fixed by the bearing fixing ring 5 at the two ends of the mounting plate 4, and one end of it is connected by the angle-adjustable fixing screw 1 and the knife bar 2 connection, the spike wood blade 3-1 and the sticky wood blade 3-2 are respectively fixed on the two ends of the knife bar 2, the knife rest 12 is also connected with one end of the return spring 14, and the other end of the return spring 14 is fixed on the fixed mounting plate 4 on.

The working principle is: when starting to work, adjust the knife rod 2 to have an initial angle of 55°-60° with the horizontal plane through the angle-adjustable fixing screw, and the cam 10 rotates counterclockwise under the action of the motor 13 and drives the roller 9 to rotate at the same time Drive the ejector rod 7 to move up and down regularly, and act on the slider 11. The slider 11 drives the tool holder 12 to rotate counterclockwise, so that the tool bar 2 drives the blades 3-1 and 3-2 to rotate counterclockwise. When the angle of rotation was 60° to 90°, after cutting the fringe wood and sticky wood simultaneously, under the action of the return spring 14, the original position is restored.
