Description

Technical Field

[0001] The invention relates to a mulberry branch cutter and belongs to the field of agricultural machinery. Background Art

[0002] Generally, mulberry branches need to be cut down in summer and winter every year, and most mulberry farmers still cut down mulberry branches by hand. This felling method requires a lot of manpower and material resources, and the labor intensity of 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. The manual felling method is difficult to meet this requirement. Chinese patents disclose some technical solutions that can realize mechanical felling of mulberry branches, but these technical solutions have more or less some shortcomings, such as: 1. A large knife disc is used as a cutting tool. This cutting knife disc has a small cutting width, and it is easy to miss cutting, and it is easy to damage the mulberry branches distributed on both sides of the knife disc. Due to the improper cutting tool used, there are problems such as poor cutting effect, serious missed cutting phenomenon, low applicability, poor conveying effect, and unclean collection. 2. The structure of the device used to convey mulberry branches is not ideal, the conveying effect is not good, and it is only used for the short-distance collection and transmission of mulberry branches after cutting. There is no conveying device suitable for long distances and good conveying effect. 3. Since there is no suitable conveying device for long-distance transmission of mulberry branches, the collection devices of mulberry branch harvesters are installed on both sides of the front of the vehicle, that is, the mulberry branches are cut and transmitted to the side of the front of the vehicle over a short distance for collection, and the collected mulberry branches are placed under the side of the front of the vehicle. This method of collecting mulberry branches on the side of the front of the vehicle, after the mulberry branches are collected, they are placed 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 harvesting the mulberry branches next to it.

[0003] Among the currently disclosed patent documents, Chinese patent CN 207399875U discloses an all-in-one machine for harvesting and baling herbaceous mulberry branches, which has the following shortcomings: 1. The tool used to cut mulberry branches is a row of cutters, which are only suitable for cutting herbaceous mulberry branches with a height between 70cm and 120cm, a maximum diameter of the branch cutting part less than 10mm, and soft mulberry branches; it is not suitable for cutting mulberry branches with a height greater than 120cm, a diameter greater than 10mm, and lignified and hardened mulberry branches. The cutting speed is low and easy to get stuck. In addition, the all-in-one machine is not equipped with a longitudinal feeding chain, and the smoothness of the longitudinal feeding of mulberry branches is not optimal. 2. Only a short-distance collection and conveying device is provided for the cut mulberry branches, and no conveying device is provided for long-distance conveying of mulberry branches. Its short-distance transmission device adopts a structure in which ordinary chains are arranged up and down and cooperate with the star wheel and the pressure strip respectively. Since the surface of ordinary chains is relatively smooth, the clamping force formed between the ordinary pressure strips is not large, and it is only suitable for the transmission of soft herbaceous mulberry branches with a height of less than 1.2 meters. It has poor transmission effect 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 transmission device are not enough. It is barely acceptable for short-distance transmission of herbaceous mulberry branches, but cannot be used for long-distance transmission of mulberry branches. 3. This all-in-one machine uses the method of bundling mulberry branches on the side of the front of the vehicle. There are still problems that the side of the mulberry branches after bundling is easily crushed to crush the unharvested mulberry seedlings, and the storage position affects the walking path of the harvester when harvesting the mulberry branches next to it.

The specific beneficial effects are described as follows:

[0016] 1. The cutting and gathering device of the present invention is provided with a longitudinal transmission chain and a transverse transmission chain. The longitudinal transmission chain can ensure that the mulberry branches smoothly enter the feed channel between the two front end gathering and feeding baffles, and transmit the mulberry branches to the cutting device for cutting, and then transmit them to the side through the transverse transmission chain. The coordinated design of the longitudinal transmission chain and the transverse transmission chain has a more reasonable structure and a better gathering and transmission effect. In addition, the longitudinal transmission chain and the transverse transmission chain are driven by the same motor and have good synchronization.

[0017] 2. The cutting tool of the cutting and gathering device of the present invention is composed of two knife discs, which can smoothly cut and cut at a high speed. Whether it is a herbaceous mulberry with a low height, a small mulberry branch diameter and a soft mulberry branch, or a woody mulberry with a high height, a large mulberry branch diameter and a hard mulberry branch, the cutting work can be completed smoothly, and the cutting can be completed at the root of the mulberry branch. The cutting effect is good, the efficiency is high, the cutting rate is high, and the applicability is good.

[0018] 3. The cutting and gathering device of the present invention is provided with multiple layers of horizontal transmission chains arranged up and down, and can perform cutting and gathering operations on mulberry branches of various lengths, and has a wide range of applications.

[0019] 4. The double-sided sharp-tooth chain used in the conveying device of the present invention is composed of a chain and sharp teeth installed on both sides of the chain, and the pressure rod section of the spring pressure strip is pressed between the sharp teeth on both sides of the double-sided sharp-tooth chain. The sharp teeth on both sides of the double-sided sharp-tooth chain protrude from the chain surface, and the clamping cooperation of the spring pressure strip can clamp the mulberry branches, which are not easy to swing or loosen, and have a good clamping effect on the mulberry branches; the transmission is stable and smooth, not easy to get stuck, and the mulberry branches can be clamped stably for transmission, with high transmission efficiency, and are particularly suitable for long-distance mulberry branch transportation.

[0020] 5. The conveying device of the present invention uses springs as pressure strips. The spring pressure strips can be opened and tightened according to the size of the conveyed branches or the accumulated volume, and always maintain an effective clamping effect. The spring pressure strips have stable clamping and good effect, and can be used for conveying mulberry branches with a height of less than 2.5 meters. The diameter of the clamped mulberry branches can be expanded to 25mm. Whether it is soft herbaceous mulberry trees or hard woody mulberry trees, good conveying can be achieved, and the working range is wide. In addition, the spring pressure strips are arranged continuously to keep the branches in a continuously compressed state, and will not loosen and cause jamming, which can ensure the smooth progress of the conveying work.

[0021] 6. The conveying device of the present invention is also equipped with a guide groove below the double-sided sharp tooth chain, which has a good guiding effect on the movement of the bottom of the mulberry branch during transmission, further ensuring that the mulberry branch is not prone to jamming during the transmission process.

The collected mulberry branches are placed at a position behind the vehicle. The mulberry branches planted at this position have all been cut down. Therefore, placing the collected mulberry branches at this position will not affect the walking path of the mulberry branch cutter during the subsequent mulberry branch harvesting, nor will it crush the unharvested mulberry seedlings nearby.
