Description

A wheat harvester for returning wheat grass to the field

technical field

The utility model belongs to the field of harvesting machinery, and more specifically relates to a wheat harvester for returning wheat straw to the field.

Background technique

Wheat is an important economic crop and food product in my country. The planting area of wheat in my country is the widest. In order to improve the planting and harvesting efficiency of wheat, mechanical operations, such as seeders and wheat harvesters, have been widely used in the prior art. In order to improve the fertility of wheat fields, people often return wheat straw to the field. The return of wheat straw to the field effectively eliminates the air pollution caused by burning wheat straw. The soil is loose, the porosity is increased, and the capacity is reduced, which promotes the activity of microorganisms and the development of crop root systems. Returning wheat straw to the field has a significant effect on increasing fertilizer and production, and generally can increase production by 5% to 10%. In the prior art, the general method of returning wheat straw to the field is to crush the wheat straw, and then directly sprinkle the wheat straw to the field. In this way, a large amount of dust will be caused in the crushing of the wheat straw and the scattering of the crushed wheat straw. Immediately turn over the field, sell the wheat grass powder into the soil for rotting and fermentation, even so, when there is wind, the thatch powder will drift with the wind, which will cause pollution to the surrounding environment, and a large amount of powdered wheat straw will cover the Leaves, houses, equipment, etc., bring troubles to the environment and people's lives.

The technical solution of the utility model is a wheat harvester for returning wheat straw to the field, including a wheat harvester body, and the wheat harvester body is provided with a harvesting platform, a conveying device, a threshing device, a cleaning device and a grain box, and the conveying device Including a clamping chain, the threshing device includes a threshing drum, one end of the clamping chain is connected to the header, and the other end is connected to the threshing drum, and the threshing drum is placed at the lower part of the clamping chain, and the clamping chain is close to the threshing drum A cutting device is provided at the end, and the cutting device includes a horizontally arranged cylindrical cutting box, and a cutting drum is arranged in the cutting box, and the cutting drum includes a rotating shaft, and the two ends of the rotating shaft The fixed disks are socketed respectively, and three small shafts are evenly distributed between the two fixed disks, and the guillotine and the data disk are evenly socketed on the small shafts.

Preferably, a discharge port is provided on the lower side wall of the hay cutting box, an arc-shaped discharge screen is provided on the discharge port, and a discharge box is provided at the bottom of the arc-shaped discharge screen. The discharge box is provided with a grass raising mouth towards the rear of the wheat harvester body.

Preferably, the guillotine includes a long guillotine and a short guillotine, and the long guillotine and the short guillotine are arranged at intervals.

Preferably, the grass cutting box is provided with a grass inlet, and the end of the clamping chain close to the grass cutting box is placed above the grass inlet.

Beneficial effects of the utility model technology:

The technical solution of the utility model is a wheat harvester for returning wheat straw to the field, which changes the shortcomings of crushing the wheat straw and returning it to the field in the prior art, and uses a hay cutter device to cut the wheat straw into silk, and then returns the wheat straw to the field to form a silk The wheat straw is directly sprinkled on the field. On the one hand, because of the thinner filaments, it can quickly ferment and rot; Because it is washed away by rainwater in rainy weather, it effectively avoids the problem of powdery wheat straw walking with the wind and water, and effectively avoids the problem of environmental pollution.

detailed description

In order to make it easier for those skilled in the art to understand the technical solution of the utility model, the technical solution of the utility model is further described in conjunction with the accompanying drawings of the description.

A wheat harvester for returning wheat straw to the field, comprising a wheat harvester body, the wheat harvester body is provided with a harvesting platform, a conveying device, a threshing device, a cleaning device and a grain box, and the harvesting platform realizes that wheat ears and wheat straw Harvesting, the conveying device realizes conveying the wheat straw and wheat ears in a flat state, and transports the wheat straw and wheat ears to the top of the threshing device. Due to the heavy weight of the wheat ears, the wheat ears droop when conveyed in a flat state, and the threshing The device realizes the threshing of wheat ears, and the threshed wheat is cleaned by the cleaning device and then transported to the grain tank, and the threshed wheat straw is continuously transported by the conveying device, or the wheat straw is directly transported to the field and waits for the next step of threshing. Bundle collection, etc. or after being pulverized by a crusher, it is thrown to the field.

As shown in Figure 1 and Figure 2, the conveying device in a wheat harvester for returning wheat straw to the field includes a clamping chain 1, and the threshing device includes a threshing drum 2, one end of the clamping chain 1 is connected to the harvesting platform, and the other end is connected to the threshing machine. The drum 2 is connected, and the threshing drum 2 is placed at the lower part of the clamping chain 1, and the end of the clamping chain 1 close to the threshing drum 2 is provided with a hay cutting device, and the hay chaffing device includes a horizontally arranged cylindrical hay cutting device. Box 4, the hay cutting box 4 is provided with a hay cutting drum, the hay cutting drum includes a rotating shaft 7, fixed discs 10 are respectively sleeved on both ends of the rotating shaft 7, and the two fixed discs 10 are evenly distributed and connected There are three small shafts 9, on which guillotines 12 and data discs 11 are evenly distributed, and a discharge port is provided on the lower side wall of the chaff box 4, and an arc-shaped discharge port is provided on the discharge port.
