Description

Caragana Bush Cutter

technical field

The invention relates to the technical field of caragana, in particular to a caragana bush cutter.

Background technique

Caragana, the name of Chinese medicine, is the whole plant of Caragana intermedia of leguminous plants. Caragana is distributed in Inner Mongolia, Shaanxi, Gansu, Ningxia and other places. It has the effect of nourishing yin and blood, and promoting blood circulation. Medical value, so it is often planted and harvested;

At present, when harvesting caragana, it is mostly manual harvesting or mechanical harvesting. Manual harvesting requires a large amount of labor, and the harvesting efficiency is slow. Most of the knives are the same during mechanical harvesting. When cutting caragana in different positions, if the knife is not suitable It will damage the knives, or the cut caragana will not work well, making it inconvenient to cut.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the problem that when harvesting caragana, it is mostly manual harvesting or mechanical harvesting. The manual harvesting requires a large amount of labor, the harvesting efficiency is slow, and the knives are mostly the same during mechanical harvesting. When the position of the knives is not suitable, the knives will be damaged, or the cutting effect of the caragana is not good, which is inconvenient for cutting.

In order to achieve the above object, the present invention adopts the following technical solutions:

A caragana bush cutter, comprising: a cutting disc; a disc serrated knife, which is detachably connected to the cutting disc; a throwing knife, which is rotatably connected to the cutting disc; an inner cutting knife, which is connected to the cutting disc On the disc, the cutting disc is provided with a cutting groove that matches the inner cutting knife; wherein, the inner cutting knife, the disc serrated knife, and the throwing knife are sequentially arranged along the cutting disc from the inside to the outside .

Preferably, a rotating plate is rotatably connected to the cutting disc, the rotating plate is arranged in the rotation direction of the throwing knife, the upper end of the rotating plate is fixedly connected with a grinding disc, and the lower end of the rotating plate is fixedly connected with a U-shaped elastic piece , the end of the U-shaped elastic piece away from the rotating plate is fixedly connected to the cutting disc.

Preferably, the cutting disc is connected with a mounting frame through threads, and the mounting frame is rotatably connected with the disc serrated knife.

Preferably, a pressing groove is provided on the cutting disc, and a pressing member is slidably connected in the pressing groove, and the pressing member is used for pressing the serrated knife and the mounting frame of the disc.

Preferably, the pressing member includes a pressing plate sliding in the pressing groove and a pressing shaft fixed on the pressing plate, and the mounting frame is provided with a shaft groove matching the pressing shaft.

Preferably, a first elastic cord is fixedly connected to the upper end of the pressing member, and an end of the first elastic cord away from the pressing member is fixedly connected to the cutting disc.

Preferably, the cutting disc is provided with a piston groove, the piston groove communicates with the pressing groove, a piston pressing plate is slidably connected in the piston groove, and a piston driving column is fixedly connected to the upper end of the piston pressing plate, and the piston driving column is fixedly connected to the upper end of the piston pressing plate. One end of the piston driving column away from the piston pressing plate is attached to the rotating plate, the lower end of the piston pressing plate is fixedly connected with a piston spring, and the end of the piston spring away from the piston pressing plate is fixedly connected to the cutting disc.

Preferably, it also includes a brush, the brush is attached to the disc serrated knife, and the brush is connected to the cutting disc.

Preferably, the brush is rotatably connected to the cutting disc, a driving rope is fixedly connected to the brush, the end of the driving rope away from the brush is fixedly connected to the throwing knife, and one end of the cutting disc is fixedly connected There is a limit rod, and the limit rod is matched with the brush.

Preferably, it also includes: a frame; an upper flange, which is connected to the frame by bolts; a lower flange, which is rotatably connected to the upper flange and is connected to the cutting disc by bolts; a drive shaft , which is rotatably connected to the frame and fixedly connected to the lower flange for driving the cutting disc to rotate.

Compared with the prior art, the present invention provides a caragana bush cutter, which has the following beneficial effects:

1. This caragana shrub cutter can fix the cutting disc on the frame through the lower flange and the upper flange. At this time, an external drive motor is used to drive the drive shaft to rotate, so that the drive shaft drives the cutting circle. Turning the disc can trim the strips of the lemon sticks:

When the cutting disk rotates, it will drive the throwing knife and the inner cutting knife to rotate. Since the serrated disk rotates on the mounting frame, the serrated disk does not rotate or rotates slowly, that is, the serrated disk rotates in the circumferential direction. Relative displacement with the cutting disc;

And the throwing knife is located at the outermost end of the cutting disc. At this time, the throwing knife will trim and cut the branches and leaves of the caragana when it rotates. At this time, the brush can brush the disc serrated knife to remove the caragana shavings left after cutting;

When the hardness of the cut caragana is high, the caragana will collide with the throwing knife, which is easy to damage the knife head of the throwing knife, and the throwing knife will rotate when it is hit, so that the throwing knife gradually approaches the rotating plate, and is in contact with the rotating plate. When they are attached to each other, the abrasive disc will rub the blade of the throwing knife to improve the sharpness of the throwing knife;

It should be understood that under the action of the U-shaped shrapnel, the abrasive disc can always be attached to the throwing knife, and when the throwing knife is attached to the rotating plate, the piston driving column will be pressed to slide down, thereby driving the piston pressing plate down and the piston. The spring is compressed, the piston pressing plate presses the gas in the piston groove into the pressing groove, and then the pressing member can be pressed to slide, so that the pressing member locks the mounting frame and the disc serrated knife together, and then the disc is The serrated knife can be rotated to cut the branches with higher hardness, and the cutting effect is better;

Furthermore, when the throwing knife rotates, the brush will be driven to rotate by the driving rope, so that the brush will rotate, not located at the outermost end of the cutting disc, that is, not in contact with the caragana, which can protect the brush. The driving rope does not affect the friction effect between the throwing knife and the abrasive disc, and the driving rope can be passed through the lower end of the rotating plate;

When the hardness of caragana is greater or the branches are thicker or missed, the inner cutting knife can be used for further cutting, and the cutting effect is better;

The parts not involved in the device are the same as the existing technology or can be realized by using the existing technology. The present invention can cut different thicknesses of Caragana branches by setting a throwing knife, a disc serrated knife, and an inner cutting knife, and the cutting effect is Well, it is convenient to brush the disc serrated knife by setting the brush, and it is convenient to rub the throwing knife by setting the abrasive disc, so as to improve the sharpness of the throwing knife and the cutting effect is better.
