Problems solved by technology

The device drives the vibrating screen to vibrate through the set motor to screen the grains, and the screening speed can be changed by adjusting the valve of the feeding funnel, and the screen mesh of the vibrating screen and the adjustment of the screening device can be changed according to the type of grains. The inclined angle achieves the purpose of screening different grains, but the device can only screen some debris with large particles, and debris such as dust, branches and leaves cannot be effectively cleaned, so the device needs to be improved

Embodiment 1

[0026] see Figure 1-5 , a grain separation and screening device, comprising a base plate 1, a second support column 10 is provided on the left side of the upper surface of the base plate 1, a feed hopper 11 is provided on the upper end of the second support column 10, and a feed hopper 11 is provided on the upper surface of the base plate 1, and the right side of the upper surface of the base plate 1 A first support column 2 is provided, and the upper end of the first support column 2 is rotatably connected to the right side of the lower surface of the sieve plate 3. The middle part of the upper surface of the bottom plate 1 is provided with a first fixed plate 6, and the upper part of the first fixed plate 6 rotates Connected to the first rotating shaft 7, the top of the first fixed plate 6 on the front side is provided with a first driving motor 5, the output shaft of the first driving motor 5 is fixedly connected to the front end of the first rotating shaft 7, and the middl...

Embodiment 2

[0029] see figure 1 , the other content of this embodiment is the same as that of Embodiment 1, except that: the first baffle 9 is provided on the left side of the upper surface of the bottom plate 1 . The middle part of the first baffle plate 9 is provided with air vent, after the fan 19 in the device blows the dust branches and leaves in the grain to the right, the first baffle plate 9 can play the effect of blocking, makes dust and branches and leaves along the first baffle plate 9. A baffle 9 falls on the left side of the bottom plate 1, which is convenient for later collection and treatment, and prevents the problem of environmental pollution.

[0030]During the implementation of the present invention, the grains that need to be screened are poured into the feed hopper 11, at this time, the first drive motor 5 and the second drive motor 25 are started, and the output shaft of the first drive motor 5 drives the first rotating shaft 7 to rotate , the first rotating shaft 7...

Abstract

The invention relates to the technical field of grain screening, and discloses a grain separation screening device. The device comprises a bottom plate, wherein the left side of the upper surface of the bottom plate is provided with a second supporting column, the upper end of the second support column is provided with a feeding hopper, a first supporting column is arranged on the right side of the upper surface of the bottom plate, the upper end of the first supporting column is rotatably connected with the right side of the lower surface of a screen plate, a first fixing plate is arranged inthe middle of the upper surface of the bottom plate, the upper portion of the first fixing plate is rotatably connected with a first rotating shaft, a first cam is arranged in the middle of the firstrotating shaft, second fixing plates are arranged in the left side and the right side of the feeding hopper, sliding rods are slidably connected to the lower portions of the second fixing plates, second baffles are arranged in the middles of the sliding rods, and third baffles are arranged at the right ends of the sliding rods. According to the grain separation screening device, in a grain falling process, airflow generated by a fan can blow away sundries with lighter weight, so that grain is subjected to preliminary impurity removal processing before being screened through the screen plate.

Description

technical field [0001] The invention relates to the technical field of grain screening, in particular to a grain separation and screening device. Background technique [0002] After the rice is harvested, the grain should be preliminarily cleaned of impurities to ensure that the grain can pass through the subsequent equipment in various processes for safe transportation, prevent equipment failure and damage, and also improve the efficiency of cleaning machinery and other equipment. The method adopted by the existing grain screening device: through the friction between the screen and the grains, the grains are screened out from the opening of the drying net, and the impurities larger than the size of the grains are removed on the drying net. There are many disadvantages in adopting this scheme: it is difficult to remove all impurities at one time. Impurities in grains usually include long-fiber impurities such as masonry, mud, and straw. Different impurities have different p...
