As shown in fig. 1-3, the utility model provides a walnut kernel screening and conveying device, which comprises a frame 1, wherein a roller conveyor is arranged in the frame 1, and a feeding port 2 is arranged at the feeding end of the roller conveyor on the frame 1. The walnut kernel raw materials contain the different raw materials of particle diameters such as complete walnut kernel, the fragment of big granule, granule fragment, powder, the utility model discloses a separate and collect alone the raw materials of above-mentioned different particle diameters promptly, the follow-up processing through different modes of the raw materials of different particle diameters forms the finished product.

The utility model discloses a roller conveyor comprises a plurality of parallel arrangement's roller 3, and the interval between roller 3 increases along direction of delivery gradually, forms blanking passageway 4 between roller 3, is provided with a plurality of material holding groove 5 in roller conveyor's below. During the use, with the walnut kernel raw materials from pan feeding mouth 2 on throwing into roller conveyor, preferably, be provided with the delivery sheet of slope on the pan feeding mouth 2, the walnut kernel raw materials is with sliding mode on dropping to roller conveyor, avoids taking place the collision between the raw materials.

Each roll shaft 3 of the roller conveyor is composed of a central rod 31, a roll surface 32 and a brush mechanism, wherein the central rod 31 is a metal rod, two ends of the central rod 31 are connected with a motor through a transmission device and rotate, for example, transmission gears can be arranged at two ends of the central rod, a transmission chain is arranged on the motor, and the central rod is driven to rotate through the meshing action of the transmission gears and the transmission chain; other transmission modes are as follows: belt drive, gear drive, etc., are also suitable for use in this application.

Further, the roll surface 32 is wrapped and arranged outside the central rod 31, the roll surface 32 is made of a flexible material, the brush mechanism comprises a brush rod 33 and a brush 34, one end of the brush rod 33 is fixedly arranged on the central rod 31, the brush 34 is fixedly arranged at the other end of the brush rod 33, the length of the brush rod 33 is smaller than the thickness of the roll surface 32, and the outer end of the brush 34 protrudes out of the outer surface of the roll surface 32. Preferably, the roll surface 32 is formed of a foam layer, sponge layer or cotton layer. The roll surface 32 is fixed to the center rod 31 by means of adhesion.

Because the walnut kernel material is more fragile, when moving on roller conveyor, if the roller is the rigidity roller, the walnut kernel is further cracked under the extrusion easily, reduces the large granule yield. Therefore, the utility model discloses set up the roll surface into flexible roll surface, even there is the fragment that a small number of diameters are close blanking passageway width to be extruded and enter into between two rollers, through the cushioning effect of roll surface, the fragment can not further smashed yet, has guaranteed the integrality of granule. Further, because some walnut powder or garrulous skin can be attached to the walnut-meat surface or hide in the outside sunken position of walnut-meat, or on attaching to the roll surface, the utility model discloses set up the brush structure and come to brush this part material and remove. Because the length of the brush rod is less than the thickness of the roller surface, the existence of the brush rod can not influence the materials passing through the blanking channel. Preferably, the number of the hairbrush structures is 4 or 6, and the hairbrush structures are uniformly distributed on the roll shaft. On one hand, in the rotation process of the roll shaft, the brush continuously cleans the adjacent roll surface to clean the powder attached to the roll surface; on the other hand, when the hairbrush rolls to the upper layer of the roller conveyor, the hairbrush plays a certain stirring role on the raw materials at the upper part, and the raw materials are stirred to continuously move forwards; on the other hand, at raw materials operation in-process, the large granule raw materials can not drop, and the brush can be cleaned the surface of large granule raw materials, further gets rid of the powder.

Further, the utility model discloses a blanking passageway 4 uses the three to be a set of, and every group blanking passageway 4's width is the same, and blanking passageway 4's width increases along direction of delivery in proper order with group as the unit.
