The shrimp screening machine
Technical field
The utility model relates to a kind of equipment that is used for aquatic products are carried out by size sizing screening, specifically is meant a seed shrimp screening machine.
Background technology
At present, processing of aquatic products enterprise is carrying out first being processed to aquatic products such as shrimp, wants prawn to carry out sizing screening by size earlier, to select for use the shrimp of suitable size in person to process according to the needs of shrimp products.Traditional shrimp sizing screening mode is artificial screening and mechanical grading.Artificial screening labour intensity is big, and efficient is also low, can not satisfy the needs of large-scale production; Though existing screening machinery screening effeciency is higher, structure is complicated, and cost is higher, and the prawn body has certain destruction during screening, influences the quality of shrimp products.
Therefore, provide a kind of simple in structure, screening effeciency is higher, and the shrimp screening machine that can not destroy the shrimp body during operation becomes the industry technical issues that need to address.
Summary of the invention
It is a kind of simple in structure that the utility model technical issues that need to address are to provide, and screening effeciency is higher, can not destroy the shrimp screening machine of shrimp body during operation.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the shrimp screening machine; Comprise frame, feeding conveying belt, described frame tilts and is provided with several screening rollers, and the output of described feeding conveying belt is arranged on the top of the higher end of screening roller; Described screening roller is arranged in parallel and is provided with; The diameter classification from top to bottom of screening roller is dwindled, and described frame is provided with and drives the motor that each screening roller rotates in the same way, described frame under the screening roller, be provided with screen roller perpendicular and with several corresponding discharging conveyer belts at different levels.
Described frame the screening roller at different levels below be respectively equipped with funnel, the outlet of funnel connects between each discharging conveyer belt and the screening roller and is provided with funnel.
The diameter of described screening roller divides six grades to dwindle from top to bottom.
Owing to adopted said structure, when the utility model used, shrimp body to be screened was delivered to the upper end of screening roller through feeding conveying belt; Motor drives each screening roller and rotates in the same way, and the shrimp body to lower slider, dwindles owing to screen the diameter classification from top to bottom of roller under the effect of gravity; Interval between the adjacent screening roller then classification increases; The shrimp body drops on the discharging conveyer belt between adjacent screening roller, again through the output of discharging conveyer belt, accomplishes size fractionation screening operation.The utility model is simple in structure, and screening effeciency is higher, can not destroy the shrimp body during operation, can enhance productivity effectively, satisfies the needs of automated production.

The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
As depicted in figs. 1 and 2; The described shrimp screening machine of the utility model; Comprise frame 1, feeding conveying belt 2, described frame 1 tilts and is provided with several screening rollers 3, and the output of described feeding conveying belt 2 is arranged on the top of the higher end of screening roller 3; Described screening roller 3 is arranged in parallel and is provided with, and manages suitable interval between the adjacent screening roller 3.The diameter classification from top to bottom of screening roller 3 is dwindled, and preferred, the diameter of described screening roller 3 divides six grades to dwindle from top to bottom.Because the diameter classification from top to bottom of screening roller 3 is dwindled; Interval between the adjacent screening roller 3 is then classification increase from top to bottom; Described frame 1 is provided with and drives the motor that each screening roller 3 rotates in the same way, described frame 1 screen be provided with under the roller 3 with screen roller 3 perpendicular and with several corresponding discharging conveyer belts 4 at different levels.
Described frame 1 screening roller 3 at different levels below be respectively equipped with funnel 5, the outlet of funnel 5 connects between each discharging conveyer belt 4 and the screening roller 3 and is provided with funnel 5.On shrimp body centralized collection to the discharging conveyer belt 4 that the effect of funnel 5 is can single-stage be fallen, improve grading effect.
When the utility model used, shrimp body to be screened was delivered to the upper end of screening roller 3 through feeding conveying belt 2, and motor drives each screening roller 3 and rotates in the same way; The shrimp body under the effect of gravity to lower slider; Because the interval classification from top to bottom between the adjacent screening roller 3 increases, the shrimp body of identical size drops in the funnel 5 in same level at interval, drops down onto on the discharging conveyer belt 4 through funnel 5 again; After size fractionation screening operation is accomplished in 4 outputs of discharging conveyer belt.
In a word; The above-mentioned preferred implementation though the utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of the utility model only if such variation and remodeling have departed from the scope of the utility model.
