Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to an oat batch grain removing machine. Background Art

[0002] Oats are a low-sugar, high-nutrition, high-energy food. Oats are sweet and mild in nature, can nourish the spleen and heart, and reduce sweat. Because they are rich in soluble dietary fiber, they have become a daily healthy food for people with "three highs". They are also the only grain selected as one of the "Top Ten Healthy Foods in the World". With the improvement of people's healthy living concepts, oat foods are increasingly favored by consumers.

[0003] Oats are annual herbaceous plants of the genus Avena in the Poaceae family. They prefer cool climates and are mostly planted in high-altitude areas in northern my country. Due to the complex and changeable climate in these areas all year round, if the oats do not accumulate enough temperature during the growth period or encounter high temperatures from pollination to grain filling, the rate of oat blight will often increase, posing a technical challenge to the oat food processing industry in cleaning blight. Existing cleaning technologies focus on removing a large amount of residual stems, leaves, dust and oat blight in oats. It is necessary to manually lift the oats and use natural wind to remove them. However, this cleaning method is inefficient and does not clean up thoroughly. At the same time, it greatly increases the manpower of staff and farmers, making the staff and farmers very hard. Summary of the invention

[0004] In order to solve the problem of low efficiency in removing oat chaff in the prior art, the present invention provides an oat chaff removing machine, which can fully remove oat chaff, stems, leaves, dust and other impurities, thereby greatly improving work efficiency.

A driven gear is fixedly connected, one end of the motor one is vertically provided with a rotating shaft and extends to the inside of the air duct, the rotating shaft drives the driven gear to rotate, one end of the motor two is vertically provided with an L-shaped rocker, one end of the L-shaped rocker is rotatably connected to a connecting piece, the end of the connecting piece away from the L-shaped rocker is fixedly connected to a support plate, the base surface of the support plate is fixedly provided with motor three, one end of the motor three is axially connected to an elliptical disk, the elliptical disk is blocked with a baffle, the base surface of the baffle is vertically fixedly connected to a vertical pole, the side walls of the vertical pole are all obliquely fixedly connected with a support rod, the end of the support rod away from the vertical pole and the top of the vertical pole are detachably connected with a screen, the screen is inclined, and the lowest end passes through the discharge port.

[0006] The cleaning machine of the present invention can be used for graded cleaning. For example, since the present invention is a detachable screen, screens with different apertures can be easily replaced. The oat grain size range is 0.8 to 1.5 cm long and 0.3 cm wide, so different oat grains can be screened.

[0007] Preferably, the bottom of the shell is fixedly connected vertically downward with a support rod, and one end of the support rod away from the shell is fixedly connected with a universal wheel.

[0008] Preferably, a driving gear is provided at one end of the rotating shaft located inside the air duct, and the driving gear is meshed with a driven gear.

[0009] Preferably, the bottom of the support plate is blocked at the end portion of the support column.

[0010] Preferably, a hanging ring is fixedly provided on the bottom of the baffle and the base surface of the support plate, and a spring is hung between the baffle and the support plate through the hanging ring, and the force applied by the spring is a tensile force.

[0011] Preferably, one end of the support rod away from the vertical rod and the top of the vertical rod are both fixedly connected with a screen, and the screen is arranged obliquely, and the lowest end passes through the discharge port.

[0012] Preferably, the inner wall of the shell is provided with an inclined waste plate, and the lowest end passes through the waste opening.

[0013] Preferably, a material dropping bucket is fixedly connected to the side wall of the shell near the bottom, a material dropping port is opened at the bottom of the material dropping bucket, and the material outlet, the air duct passing through the side wall of the shell, and the material dropping bucket are arranged in sequence from top to bottom.

[0014] Preferably, a guide rod fixedly connected to the bottom of the baffle is slidably provided on the inner wall of the guide column.

[0015] The present invention adopts the above technical solution and has the following beneficial effects: 1. In the present invention, the elliptical disk is driven to rotate by motor three, and the baffle moves back and forth up and down along the contact surface of the elliptical disk, thereby causing the screen to move back and forth up and down, and the guide rod is guided and moved in the guide column, and the spring pulls the baffle and the support plate, so that the structure on the baffle runs smoothly, and motor two drives the L-shaped rocker arm to rotate, thereby causing the structure on the support plate to swing, thereby driving the screen to swing. Under the action of swinging and vibrating up and down, the screen can fully filter out oatmeal grains and other impurities in a similar way to the traditional manual screening of grains.

[0016] 2. The present invention drives the rotating shaft to rotate through a motor, and drives the rotating rod and the fan blades to rotate through the driving gear and the driven gear. Under the action of the fan blades, the fan blades suck the wind from the air inlet into the air duct and then blow it out. In the process of oats falling, the centrifugal principle is used according to the weight difference. The weight range of oat grains is 25-32g / 1000 grains. The wind force further blows out the lighter empty grains in the oats and the stems and leaves in the oat harvesting process, and the heavier oats fall into the drop bucket, making the oats cleaner.

[0017] 3. In the present invention, the oat chaff and other impurities after filtering fall onto the waste plate, and the waste plate is inclined. The oat chaff and other impurities fall to the outside from the oat chaff and other impurities, so that the oat chaff and other impurities are automatically discharged from the outside of the machine.
