Description

Front-mounted flax harvester

technical field

The utility model relates to an agricultural machine for harvesting flax, in particular to a front suspension flax harvester.

Background technique

In the past 10 years, with the continuous expansion of the scale of flax textiles in my country, the supply of flax raw materials is particularly tight, basically relying on imports, which greatly reduces the benefits of flax textile enterprises, and raw materials have become the bottleneck of the development of my country's flax industry. However, the harvesting of flax has not yet been mechanized or has a low degree of mechanization. It is basically manual work, and the flax stems are very thin and the planting density is high, so the labor intensity is high and the income of farmers is slow. In the early 1950s, several tractor-type flax harvesters were introduced from the former Soviet Union, but due to their complex structure, large size and manual cutting, they have not been used in production. At present, most of my country's hemp pulling is a self-propelled pulling hemp machine such as the 4YYZ-1.4 type and the Russian joint pulling hemp machine. There are mainly the following problems in the harvesting process of the existing domestic hemp pulling machines: a. flax stalks are easy to be pinched off; b. the harvest rate is low; c. The structure is complex and consumes a lot of power; the row spacing of the e machine tool does not match the row spacing of flax planting in Xinjiang. Although the combined hemp pulling machine in Russia can pick peaches while pulling out hemp, the loss rate of the seeds after picking peaches is very high, reaching more than 60%.

Contents of the invention

The purpose of this utility model is to provide a front-mounted flax harvester, which has reasonable design, compact structure, light weight, and is hung in front of small and medium-sized four-wheel tractors. It is flexible, high-quality work, and low energy consumption.

The purpose of this utility model is achieved in this way: a front suspension type flax harvester, including a drive wheel driven by the output shaft of the gearbox is installed at one end of the horizontal frame, and a driven wheel is installed at the other end, and the drive wheel passes through The hemp pulling belt drives the driven wheel, and the frame hinged by the hydraulic lifting device is evenly distributed and fixed to the door-shaped cantilever. At the end of the evenly distributed door-shaped cantilever, the pulling hemp wheels matching the hemp-pulling belt are respectively installed. On both sides of the wheel, and on the back of the hemp belt, tensioning wheels are respectively arranged, and the front part of the door-shaped cantilever is respectively fixed with the grain divider and the grain holder corresponding to the hemp pulling wheel and the driven wheel, which are located on the side of the driving wheel. The end of the door-shaped cantilever on the side is fixed to the horizontal cantilever, and the conveyor wheel installed at the end drives the grooved pulling wheel installed at the end of the door-shaped cantilever through the conveyor belt, so that the conveyor belt between the conveyor wheel and the grooved pulling wheel It forms a clamping mating surface with the corresponding matching hemp belt.

The utility model is characterized in that it adopts the front suspension type, which is suspended and fixed on the front part of the small and medium-sized four-wheel tractor through the support of the hydraulic lifting device. The utility model works like this: when the tractor is started and combined with the power output shaft, the power is finally transmitted to the gearbox through the universal drive shaft and the intermediate drive, and the output shaft of the gearbox drives the driving wheel to rotate counterclockwise, driving the hemp belt, and at the same time Correspondingly drive the driven wheel, the tension wheel, the hemp pulling wheel, the grooved hemp pulling wheel, the conveyer belt and the conveying wheel to move together. When the tractor is moving forward, the grain divider divides the flax into corresponding crop belts, and under the rotation of the pulling wheel, the flax is forced into the arc channel formed by the pulling belt and the pulling wheel. Under the action, the flax is forcibly pulled out. With the anticlockwise rotation of the pulling belt, the extracted flax enters the middle of the door-shaped cantilever and continues to be conveyed to the left. The extracted flax bundles are gradually merged together and conveyed to the left, and enter the conveyor belt to form a With the continuous counterclockwise movement of the pulling belt, the pulled flax is neatly and continuously laid on the left side of the machine.

The utility model adopts a hemp pulling belt and a laying belt to realize multi-row operations; its working height can be controlled by a hydraulic lifting device to adapt to different heights of flax. The damage to the flax is reduced due to the adoption of the horizontal conveying mode between the conveyor belt and the hemp pulling belt. The grain divider of the utility model corresponds to the hemp pulling wheel and is installed on the door-shaped cantilever at the same time, which simplifies the structure of the hemp pulling machine and reduces the weight of the machine. The utility model has reasonable design and compact structure, is hung in front of the four-wheel tractor, has flexible maneuverability, high operation quality and low energy consumption.
