Description

technical field [0001] The invention relates to a mulberry branch cutting machine, which belongs to the field of agricultural machinery. Background technique [0002] Generally, the mulberry branches of mulberry trees need to be felled in summer and winter every year, and most mulberry farmers still use manual felling to cut the mulberry branches. This felling method needs to consume a large amount of manpower and material resources, and the labor intensity of the workers is high, and the work efficiency is low. In addition, when cutting mulberry, it is also required to cut the mulberry branches at the root as much as possible, and the cutting height is consistent. It is difficult to meet this requirement by manual felling. The Chinese patent discloses some technical solutions that can realize mechanical felling of mulberry branches, but there are more or less some deficiencies in these technical solutions, for example: 1. Using a large cutter head as a cutting tool, this c...

AI Technical Summary

Problems solved by technology

This method of felling requires a lot of manpower and material resources, and the labor intensity of the workers is high, and the work efficiency is low.

In addition, when cutting mulberry, it is also required to cut off the mulberry branches at the root as much as possible, and the cutting height is consistent. It is difficult to meet this requirement by manual felling.

The Chinese patent discloses some technical solutions that can realize mechanical felling of mulberry branches, but there are more or less some deficiencies in these technical solutions, for example: 1. Using a large cutter head as a cutting tool, this cutting cutter head cuts The cutting width is small, it is easy to miss the cutting phenomenon, and it is easy to break the mulberry branches distributed on both sides of the cutter head

Due to the improper cutting tools, there are problems such as poor cutting effect, serious missed cutting, low applicability, poor conveying effect, and unclean collection.

2. The structure of the device for conveying mulberry branches is not ideal, and the conveying effect is not good, and it is only used for short-distance gathering and conveying of cut mulberry branches. There is no conveying device that is suitable for long distances and has a good conveying effect.

3. Since there is no conveying device suitable for long-distance transmission of mulberry branches, the collection devices of the mulberry branch harvester are installed on both sides of the front of the car, that is, the mulberry branches are cut and transported to the side of the front of the car for a short distance, and then they are collected. The mulberry branches are placed under the side of the front of the car

This way of collecting mulberry branches on the side of the front of the car, after collection, the mulberry branches are put down on the side, which is easy to crush the unharvested mulberry seedlings, and the position of the mulberry branches after collection will affect the walking path of the harvester when the mulberry branches next to it are harvested

[0003] In the currently disclosed patent literature, Chinese patent CN 207399875U discloses a kind of herbal mulberry harvesting and bundling integrated machine, which has the following disadvantages: 1. The tool for cutting mulberry branches is a cutter arranged in a row, which This kind of cutting knife is only suitable for cutting herbaceous mulberry branches. The height of herbaceous mulberry branches is between 70cm and 120cm, and the maximum diameter of the branch cutting part is less than 10 mm, which is soft. When cutting woody and hard mulberry branches, the cutting speed is low and it is easy to get stuck

In addition, the all-in-one machine is not equipped with a vertical feeding chain, and the smoothness of the vertical feeding of mulberry branches is not optimal

2. There is only a short-distance gathering and conveying device for cutting mulberry branches, and no conveying device for long-distance transportation of mulberry branches

Its short-distance conveying device adopts a structure in which ordinary chains arranged up and down are respectively matched with the reeling star wheel and the batten. Because the surface of the ordinary chain is relatively smooth, the clamping force formed between the ordinary chain and the ordinary batten is not large, and it is only suitable for heights less than 1.2. Meter, soft herbaceous mulberry branch transmission, the transmission effect is not good for mulberry branches with large diameter, high hardness, and height longer than 1.2 meters, and the working range is small

Therefore, the transmission effect and stability of the all-in-one machine transmission device are not enough, and it is barely acceptable for short-distance transportation of herb mulberry branches, but it cannot be used for long-distance mulberry branch transportation.

3. This all-in-one machine uses the method of bundling mulberry branches on the side of the front of the truck. There are still problems that the side of the mulberry branches after bundling is easy to crush the unharvested mulberry seedlings and the storage position affects the walking path of the harvester when the mulberry branches next to it are harvested.
