Hulling machine for sunflower seeds

Abstract

The invention relates to a hulling machine for sunflower seeds. The hulling machine comprises a feeding hopper, a lifting conveying belt, a large and small seed separating sieve, an upper sieve vibrating device and a lower sieve vibrating device which are arranged below a material outlet at the top of the lifting conveying belt, grinding conveying belts arranged below the upper sieve vibrating device and the lower sieve vibrating device respectively, grinding rollers arranged in middles of the grinding conveying belts, brush devices arranged above the grinding conveying belts, arc-shaped collecting plates arranged at tail ends of the grinding conveying belts obliquely downwards, a rotating centrifugal barrel arranged below material outlets of the arc-shaped collecting plates, a centrifugal barrel discharging port arranged at the lower part of the rotating centrifugal barrel, a triple separating sieve arranged below the centrifugal barrel discharging port and multiple collecting tanks arranged at material outlets of all layers of the triple separating sieve, wherein the large and small seed separating sieve comprises an upper sieve and a lower sieve; the upper sieve extends obliquely downwards to above the upper sieve vibrating device; the lower sieve extends obliquely downwards to above the lower sieve vibrating device; sieve holes are formed in the upper sieve corresponding to the lower sieve.

Description

technical field [0001] The invention relates to a sunflower seed shelling machine, which belongs to the field of shelling machinery. Background technique [0002] Dozens of sunflower seed shelling machines have come out successively in our country, but most of the shelling machines can only perform single shelling, with simple structure and poor adaptability. my country is in the early stage of sunflower seed shelling mechanization development, and the number of sunflower seed shelling machines in my country is not high. The development of sunflower seed shelling machines can not only save labor, but also improve productivity, and has a very broad market and application prospects. . Existing sunflower seed shelling machines all adopt a single rolling or centrifugal type to realize shelling, with low yield and high damage rate. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a sunflower seed shelli...
