Description

Fresh fruit raw material grading plant

Technical field

The utility model belongs to the mechanical grading device, is specifically related to a kind of spherical fresh fruit raw material grading plant.

Background technology

China is a fruit big producing country, and classification technique has important meaning to the market competitiveness and the profit level that raising China eats fruit raw automatically.

Along with the development of fruit storage processing industry and the raising of people's living standard, to fruit quality require increasingly highly, fruit is adopted back classification work and is seemed and become more and more important; And classification work is ageing strong after adopting; The operation quality standard is high, therefore, realizes that mechanization, automated job are imperative.The industrialization that fruit is produced makes and realizes that fruit is adopted the back grading machineryization and automatic technology becomes possibility.The fruit colour weight grader that fruit classification machinery can be divided into size classifier, weight grader, fruit colour grader and not only carry out classification by size but also by color and luster by operation principle.The fruit size classifier carries out classification by the fruit size, owing to select fruit size shape basically identical, helps package storage and processed, so in the fruit classification machine, use the most extensive.Operation principle: fruit is moved along the classifying screen in grid with different size or slit, and minimum fruit spills from minimum grid earlier, and big fruit is pressed the difference of size of mesh opening from spilling than macrolattice, selects the fruit of different stage successively.Can not change with the variation of fruit variety after the typing of the big perhaps grade gridding of existing size classifier floor space size.

Summary of the invention

The technical problem that the present invention will solve is, to the deficiency of prior art, provide a kind of can be to the different fresh fruit raw materials equipment of size fractionation by volume.

For realizing above-mentioned purpose, the technical solution that the utility model adopted is:

Fresh fruit raw material grading plant; Comprise screen drum, support, end cap, feed hopper, pinion, discharge bucket; It is characterized in that: screen drum is supported by the roller on the support; The tube inwall is provided with to advance to have on sieve aperture, the drum outer wall on spiral, the barrel has cog belt, and is rotated by the pinion drive tube with the cog belt engagement; Screen drum connects from little extremely big order by sieve aperture along feed end to discharge end successively, and each advances spiral to be linked to be complete helical structure; The screen drum feed end is connected with end cap, and the blanking of feed hopper is partly stretched in the charging aperture of end cap; The screen drum below is provided with discharge bucket, and screen drum discharge end below is provided with discharge bucket.

The screen-aperture of said screen drum is 30-100mm.

Said propelling spiral is single coil configuration or double-spiral structure.

The beneficial effect of the utility model

The utility model is simple in structure, and is easy to use, and floor space is little, and can change different sieve buckets flexibly according to the classification needs of different fresh fruits, and grading effect is good, and speed is fast, and production cost is low.

The specific embodiment

Embodiment 1

Like Fig. 1, fresh fruit raw material grading plant shown in Figure 2; Comprise screen drum 1, screen drum 2, screen drum 3, support 4, end cap 5, feed hopper 6, pinion 7, discharge bucket 8 and discharge bucket 9; It is characterized in that: screen drum 1, screen drum 2, screen drum 3 are supported by the roller on the support 4 10, and the tube inwall is provided with and advances spiral 11 and for single coil configuration, sieve aperture is arranged on the barrel; The screen-aperture of screen drum 1 is that the screen-aperture of 30mm, screen drum 2 is that the screen-aperture of 50mm, screen drum 3 is 70mm; Cog belt 12 is arranged on the drum outer wall, and drive the tube rotation by the pinion 7 with cog belt 12 engagements, pinion 7 is rotated by driven by motor through drive link again synchronously; Screen drum 1, screen drum 2, screen drum 3 connect from little extremely big order by sieve aperture along feed end to discharge end successively, and each advances spiral 11 to be linked to be complete helical structure; Screen drum 1 feed end is connected with end cap 5, and the blanking of feed hopper 6 is partly stretched in the charging aperture 13 of end cap 4; Screen drum 1, screen drum 2, screen drum 3 belows are provided with discharge bucket 8, and screen drum 3 discharge ends below is provided with discharge bucket 9.

During work, the fresh fruit raw material is put into feed hopper 6, partly get into cylinder 1 along blanking, under the promotion that advances spiral 10, move forward, the sieve aperture of cylinder 1 is smaller, and minimum fruit bleeds earlier in the discharge bucket 8; After getting into cylinder 2, its sieve aperture is bigger than the sieve aperture of cylinder 1, and the fruit that is fit to spills in the hopper 8; After getting into cylinder 3, its sieve aperture is bigger than the sieve aperture of cylinder 2, and the fruit that is fit to spills in the hopper 8; The bigger fruit that has not leaked gets into the discharge bucket 9 from the discharge end of cylinder 3, accomplishes the classification work of fresh fruit.

Embodiment 2

Fresh fruit raw material grading plant, its embodiment such as embodiment 1, difference is that the screen-aperture of screen drum is respectively 40mm, 60mm, 80mm, the propelling spiral is a double-spiral structure.

Embodiment 3

Fresh fruit raw material grading plant, its embodiment such as embodiment 1, difference is that the screen-aperture of screen drum is respectively 60mm, 80mm, 100mm, the propelling spiral is a triple-helix structure.
