Abstract

The utility model discloses a hand power drum type grading and screening machine for chestnut which comprises a drum screen 1, a drum screen support ring 2, a drum screen bracket 3, and rolling wheels 4; the drum screen 1 is a conical body; the mesh 5 of the drum screen 1 is divided into 3-4 segments which are arranged from the long diameter end to the short diameter end of the drum screen 1 in turn, and the diameters of the segments become longer one by one; the mesh 5 of every segment has the same diameter, so that the graded chestnuts in the same segment can be same in size; a feed hopper 6 is arranged above the long diameter end of the drum screen 1; the opening rim of the drum screen is equipped with rolling tracks 7, and the drum screen bracket 3 which is corresponding to the rolling tracks 7 is equipped with rolling balls 8; the short diameter end of the drum screen 1 is equipped with a driving toothed ring 9; the drum screen bracket 3 corresponding to the driving toothed ring 9 is equipped with a hand power rotating gear 10; the hand power rotating gear 10 meshes with the driving toothed ring 9. The hand power drum type grading and screening machine for chestnut is applied especially to the families or the purchasing centers, with simple structure and low cost.

Description

Hand drum formula chestnut sizing screening machine

Technical field

The utility model relates to a kind of improvement of chestnut separator, and specifically a kind of hand drum formula chestnut sizing screening machine is applicable to the sizing screening of peasant household to the chestnut before sales.

Background technology

Mountain area plantation Chinese chestnut, be the approach that hill farmer is got rich, but in the sale of chestnut, to choose be an important step in classification to chestnut.At present, the peasant still prolongs mostly the sizing screening of chestnut and uses hand picking, and efficient is low, and labour intensity is big; The straight rotary screen sizing screening of the employing inclined that also has, but this device structure complexity, the manufacturing cost height is not suitable for using in peasant family.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, cost is low, efficient is high, labour intensity is little, is specially adapted to the hand drum formula chestnut sizing screening machine that peasant family and purchasing station are used.

For reaching above purpose, the technical scheme that the utility model adopted is: this hand drum formula chestnut sizing screening machine, comprise rotary screen, the rotary screen support ring, rotary screen support and roller constitute, it is characterized in that rotary screen is a bullet, rotation by this bullet rotary screen, chestnut in the rotary screen is rolled to the little end of diameter from the big end of rotary screen diameter, need not in rotary screen, establish propulsion plant or rotary screen tilt is installed, simplified the structure of rotary screen, the mesh of rotary screen divides 3-4 joint, arrange in turn to the little end of diameter from the end that the rotary screen diameter is big, and mesh aperture becomes big by joint, select little earlier, after select big, the aperture unanimity of every joint mesh, make the chestnut of in a joint, selecting equally big, above the big end of rotary screen diameter, establish feed hopper, mouthful along on establish and roll rail, establish ball with rolling on the corresponding rotary screen support of rail, establish the driving ring gear at the end that the rotary screen diameter is little, establish the hand traverse moving gear with driving on the corresponding rotary screen support of ring gear, the hand traverse moving gear with drive the ring gear engagement, by the rotation of hand traverse moving gear, rotary screen is rotated.The utility model is also implemented by following measure: also be provided with fixedly slipping ring on the bell of rotary screen, fixedly slipping ring is enclosed within on the rotary screen that drives the ring gear inboard, fixedly the upper side frame of slipping ring and rotary screen support is fixed, like this, in hand traverse moving gear rotation process, drive ring gear and can not break away from or deflection hand traverse moving gear; The upper face of described rotary screen support is a taper arc tiling, and its taper radian is consistent with rotary screen bullet radian, so that the putting into of the rotary screen that can suit; Establish classification Li Dou in the rotary screen support of rotary screen bottom side, classification Li Dou also establishes 3-4, and is corresponding with the merogenesis of mesh respectively.

The beneficial effects of the utility model are: compare with the rotary screen of present use, not only the efficient height, can reduce labor intensity, and simple in structure, production cost is low, be particularly suitable for family or purchasing station and use.

Fig. 2 is that the utility model is along the A-A cross-sectional schematic.

The specific embodiment

Make the utility model with reference to accompanying drawing 1,2.This hand drum formula chestnut sizing screening machine, comprise rotary screen 1, rotary screen support ring 2, rotary screen support 3 and roller 4 constitute, it is characterized in that rotary screen 1 is bullet, rotation by this bullet rotary screen, chestnut in the rotary screen 1 is rolled to the little end of diameter from the big end of rotary screen 1 diameter, need not propulsion plant and rotary screen tilted to install, simplified the structure of rotary screen, 5 fens 3-4 joints of the mesh of rotary screen 1, arrange in turn to the little end of diameter from the end that rotary screen 1 diameter is big, and it is big by the joint change, the mesh 5 diameter unanimities of every joint, make the chestnut of in a joint, selecting equally big, above the big end of rotary screen 1 diameter, establish feed hopper 6, mouthful along on establish and roll rail 7, establish ball 8 with rolling on the rail 7 corresponding rotary screen supports 3, establish driving ring gear 9 at the little end of rotary screen 1 diameter, establish hand traverse moving gear 10 with driving on the ring gear 9 corresponding rotary screen supports 3, hand

traverse moving gear

10 and 9 engagements of driving ring gear, by the rotation of hand traverse moving gear 10, rotary screen 1 is rotated.On the bell of rotary screen 1, also be provided with fixedly slipping ring 11, fixedly slipping ring 11 is enclosed within on the rotary screen 1 that drives ring gear 9 inboards, fixedly slipping ring 11 is fixed with the upper side frame of rotary screen support 3, like this, in hand traverse moving gear 10 rotation processes, drive ring gear 9 and can not break away from or deflection hand traverse moving gear 10; The upper face of described rotary screen support 3 is a taper arc tiling, and its taper radian is consistent with rotary screen 1 bullet radian, so that the putting into of the rotary screen that can suit; Establish classification Li Dou 12 in the rotary screen support 3 of rotary screen 1 bottom side, classification Li Dou 12 also establishes 3-4, and is corresponding with the merogenesis of mesh 5 respectively.
