Description

A new type of thresher

technical field

The utility model belongs to the field of agricultural machinery, in particular to a novel threshing machine.

Background technique

The current small-scale agricultural threshing machine threshing grain is artificially put the ear part of rice on the threshing cylinder, which requires human assistance, low degree of automation, and low efficiency. And in the threshing process, people are vulnerable to rice ear splashing, or do not hold the rice to make the rice entangled on the threshing cylinder, which is difficult to handle. Some of the current small agricultural threshing machines have their own separation of grain and waste grass, but the separation is not complete, and the waste grass is difficult to deal with. After the grains are concentrated in the grain box, it needs to be shut down and processed manually, which is time-consuming and laborious, and affects work efficiency.

Utility model content

In order to solve the problems existing in the above technologies, the utility model provides a novel threshing machine with high degree of automation, high efficiency and less human assistance.

Its technical solution is:

A new type of threshing machine, including a rice feeding area, a grain waste grass mixing bin, a transmission assembly, a grain bin, a lifting unloading area and a casing, and the rice feeding area, a grain waste Grass mixing bin and grain bin. There is a threshing drum inside the rice feeding area, a grain and waste grass mixing bin under the rice feeding area, and a transmission assembly on the side of the grain and waste grass mixing bin. A grain bin is arranged below the grain waste grass mixing bin, and a lifting unloading area is arranged on the casing on the side of the grain bin.

Further, the rice feeding area includes a feed inlet, a baffle, a support plate, a threshing cylinder, a screen, a grass retaining cover and a grass outlet, and a baffle is hingedly arranged on the casing at the feed inlet, The casing at the grass outlet is hinged with a grass cover, and a threshing drum is installed under the casing between the baffle plate and the grass cover. One end is fixed on the casing by a spring, the end of the support plate close to the grass outlet is directly fixed on the casing, and the middle of the support plate is set as a screen.

Further, the grain and waste grass mixing bin includes a movable screen, a blowing device and a waste grass outlet baffle, a blowing device is arranged on the casing above one end of the movable screen, and a blowing device is arranged on the casing above the other end of the movable screen. A waste grass outlet baffle is provided.

Further, the transmission assembly includes an eccentric wheel, a pulley set, a screen connecting rod and a frame connecting rod, the movable screen is provided with one end of the blowing device hinged with the casing, and the movable screen is provided with a waste grass outlet baffle. One end is hinged with the screen connecting rod and one end of the frame connecting rod, the other end of the frame connecting rod is hinged with the casing, the other end of the screen connecting rod is connected with the eccentric wheel, the eccentric wheel is coaxially connected with the pulley group, and the pulley group Connect with threshing drum.

Further, the bottom of the grain bin is inclined, and the lower end of the grain bin is provided with a lifting unloading area, which includes a support plate, a discharge port, a bottomed hopper, a bottomless hopper, and a shell for the unloading area. The lower end of the grain silo is connected to the shell of the unloading area, and the shell of the unloading area is provided with a discharge port, and the shell of the unloading area is provided with a support plate, and the circumference of the support plate is alternately provided with bottom hoppers and bottomless hoppers.

Further, the threshing cylinder includes a cylinder and a helical rack, and the cylinder is provided with a plurality of helical racks.

When the utility model works, the staff feeds the rice from the feed port of the rice feeding area, there is a small gap between the threshing cylinder and the support plate, and the rice is sent into the gap between the threshing cylinder and the support plate At the same time, the helical rack on the threshing drum separates the straw from the grain through the force generated by the support plate, and at the same time, the rotating threshing drum pushes the straw forward and is collected from the grass outlet. During this process, people can adjust the baffle and the grass cover to ensure that the straw and grain in the threshing machine will not splash out. After the straw and the grain are separated, the grain and a part of waste grass fall into the grain waste grass mixing bin through the screen on the support plate. The waste grass is lighter in weight, and the grain contains more moisture and is heavier in weight. Most of the waste grass will be blown out of the grain waste grass mixing bin by the blower device from the waste grass outlet baffle during the falling process, while a small part of waste grass and grain will fall on the movable screen. When the pulley group drives the threshing cylinder to rotate, it also drives the eccentric wheel to rotate. During the rotation of the eccentric wheel, it drives the screen connecting rod to move, and the frame connecting rod restrains the screen connecting rod, so that the screen connecting rod and the movable screen are hinged. The movement track at the place shrinks, and finally forms the vibration of the movable screen. The movable sieve vibrates to let the upper grains fall into the grain bin through the sieve holes, and a small part of waste grass is isolated by the movable sieve, and blown out from the waste grass outlet baffle by the blowing device. The grains fall into the grain bin. Since the bottom of the grain bin is inclined, the lower end of the grain bin is provided with a lifting unloading area. The grains will be concentrated in the shell of the unloading area of the lifting unloading area. The supporting plate in the shell rotates, the bottomless hopper on the supporting plate loosens the grains, and the bottomed hopper picks up and carries the loose grains, and sends them to the discharge port for collection.

The beneficial effects of the utility model:

The utility model does not need to manually hold the rice for threshing, directly sends the rice into the threshing machine, saves energy and separates grains and straws, has safe and convenient operation, and high threshing efficiency. The utility model adopts two methods of vibrating screen and air blowing to separate grain and waste grass at the same time, so that the separation of grain and waste grass is more thorough, the effect is better, and the waste grass is conveniently treated. The bottom of the grain bin of the utility model is arranged obliquely, which can accumulate grains in a concentrated manner and facilitate the collection of grains. The grain bin is located at the bottom of the threshing machine, and it is very inconvenient to directly process the grains therein. Out of the material, easy to collect. The utility model has the advantages of simple structure, low cost, convenient use and high degree of automation, can reduce people's labor force and working time in many aspects, and has strong practical value.
