Description

wheat thresher shredder

technical field

The utility model belongs to the improvement of the structure of a wheat thresher, in particular to a wheat thresher and grass cutter.

Background technique

At present, most of wheat is threshed with a thresher to save labor and reduce labor intensity. However, the existing wheat thresher has a relatively single function, and generally can only perform the threshing work of wheat, but cannot process a large amount of wheat straw.

Utility model content

The purpose of the utility model is to provide a wheat thresher and shredder, which not only has a simple structure and is easy to manufacture, but also can complete the process of wheat threshing and crushing wheat straw simultaneously, saving time and effort, and high working efficiency.

The purpose of this utility model is achieved in this way: a wheat threshing machine, including a frame, a threshing drum with a threshing roller is placed horizontally on the frame, one end of the threshing roller is equipped with a pulley, one side of the threshing drum There is a feed hopper at one end and a grass outlet at the lower part of the other side. A section of the threshing roller shaft above the grass outlet is equipped with broken grass hammers and fan blades evenly, and the fan blades are connected with the side end of the threshing drum. The surfaces are vertical, and a cylindrical sieve plate is set on the inner wall of the axial threshing drum around the grass hammer blade and the fan blade. There is a gap between the sieve plate and the peripheral wall of the threshing drum; A threshing scraper is set, and the opening of the threshing scraper faces the rotation direction of the threshing roller. On the axial inner wall of the threshing roller around the threshing roller, there is a push guide plate that guides the material from the feed hopper to the grass outlet. The push guide plate is in a spiral shape. Linear continuous arrangement.

When the utility model is in use, the pulley installed at one end of the threshing roller is connected with the tractor and other power machinery through the transmission belt, and the tractor and other power machinery drives the threshing roller to rotate at a high speed, and then put the harvested wheat straw with ears into the hopper together Inside, the threshing scraper installed on the high-speed rotating threshing roller will continuously scrape off the ears of wheat and carry out the threshing work. At the same time, under the action of the spirally continuously arranged pushing guide plate, the wheat straw continuously runs towards the grass-breaking hammer along with the high-speed rotating threshing roller, and is gradually crushed by the grass-breaking hammer, and is discharged from the grass discharge port after being screened by the sieve plate. . The utility model has simple structure, is easy to manufacture, can complete the process of wheat threshing and crushing wheat straw synchronously, saves time and labor, has high work efficiency, saves investment and reduces use cost.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing.

Accompanying drawing is the three-dimensional structure schematic diagram of the utility model.

Detailed ways

A wheat threshing and grass cutting machine, as shown in the accompanying drawings, includes a frame on which a threshing drum 5 with a threshing roller 3 is placed horizontally, and a ventilation hole 7 is arranged under the bottom surface of the middle part of the threshing drum 5 . One end of threshing roller 3 is equipped with pulley, and pulley is connected to get final product by the power take-off pulley of power machinery such as tractor by transmission belt during use. One end of the threshing drum 5 is equipped with a feed hopper 1 and the lower part of the other end is equipped with a grass discharge 14, and a section of the threshing roller 3 rotating shaft above the grass discharge opening 14 is respectively evenly arranged with a grass-breaking hammer 12 and a The fan blade 13 and the grass-breaking hammer 12 are used to crush the wheat straw, and the fan blade 13 can blow out the crushed wheat grass debris from the grass outlet 14 . The fan blade 13 is perpendicular to the side end surface of the threshing drum 5, and a cylindrical sieve plate 11 is arranged on the inner wall of the axial threshing drum around the weed hammer blade 12 and the fan blade 13, and there is a gap between the sieve plate 11 and the 5 peripheral walls of the threshing drum. In the gap, the sieve plate 11 is used to sieve the wheat straw so as to improve the crushing rate of the wheat straw.

As shown in the accompanying drawings, the peripheral wall of the threshing drum installed around the broken grass hammer blade 12 and fan blade 13 expands outwards to form a wheat straw crushing cover 10, which is convenient to improve the wheat straw crushing efficiency in order to expand the accommodation rate after the wheat straw is crushed, and prevents Wheatgrass is congested.

Threshing scrapers 4 are evenly distributed on the outer peripheral roller surface of the threshing roller 3 at staggered intervals, and the openings of the threshing scrapers 4 face the rotation direction of the threshing roller 3 . On the axial inner wall of the threshing drum 5 around the threshing roller 3, there is a push guide plate 6 that guides the material from the feed hopper 1 to the grass outlet 14, and the push guide plate 6 is continuously arranged in a spiral shape.

On the roller surface of the side end of the threshing roller 3 close to the grass-breaking hammer blade 12, the throwing pocket plate 8 is evenly distributed, and the throwing pocket plate 8 is bent to be half a cylinder or half a cylinder, and the throwing pocket plate 8 around the threshing cylinder 3 inner peripheral walls are evenly distributed with guide vanes 9 at intervals, and each guide vane 9 is arranged obliquely to the weed hammer blade 12 direction.

The threshing scraper 4 is concave or semi-cylindrical, and is used to scrape the ears of wheat from the stalks and beat and thresh the ears of wheat at the same time.

Feeding roller 2 is placed horizontally in the feed hopper 1, and feeding teeth are evenly distributed on the rotating shaft of feeding roller 2, in order to improve and speed up the feeding speed of wheat straw. One end of the feed roller 2 links to each other with a driving motor rotating shaft installed on the frame. One end of feed roller 2 is equipped with the transmission wheel by belt-driven by said belt pulley. The feed roller 2 can be driven in these two ways.
