Detailed Description
In order to make the technical solutions of the present invention better understood, the following description of the technical solutions of the present invention with reference to the accompanying drawings of the present invention is made clearly and completely, and other similar embodiments obtained by a person of ordinary skill in the art without any creative effort based on the embodiments in the present application shall fall within the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
As shown in fig. 1-3, a rapid egg counting method includes:
s100, acquiring and judging whether eggs 3 exist on the conveyor belt 1 or not based on the shielding length of a row of infrared light sources;
s200, recording the shielding length of the infrared light source when the eggs 3 are judged to be present;
s300, calculating the total number of the eggs 3 based on the shielding length of the infrared light source and the preset maximum shielding length of the eggs 3.
Further, the specific method for judging whether eggs 3 exist on the conveyor belt 1 comprises the following steps: comparing the shielding length X of the infrared light source with the width M of the conveyor belt 1, and when X is larger than or equal to M, the number of 3 eggs is 0. Because the fixed supporting medium that needs of egg 3, in order to avoid the wrong discernment of supporting medium for egg 3 with infrared inductor, consequently carry out the judgement process that has or not egg 3 on conveyer belt 1 before the discernment, only have egg 3 on the conveyer belt 1 when, just carry out next step and shelter from record length, and then the procedure of count.
Further, the method for recording the shielding length of the infrared light source when the egg 3 is judged to be present comprises the following steps: when X < M, recording is started from one end of the shielded light source as X1, and when the shielding is disconnected and the shielding is started again as X2, recording is sequentially performed in segments until Xn at the other end. Eggs 3 randomly scatter on the conveyor belt 1, and the eggs 3 are automatically centered and arranged into a plurality of rows according to the spherical characteristics of the eggs by arranging the specific conveyor belt 1, so that the uncertainty of the transverse dimension is reduced, and the number of the eggs 3 on the plane can be obtained by only counting the number of the eggs 3 on the longitudinal dimension and overlapping the determined transverse dimension.
Further, based on the preset maximum shielding length N of the eggs 3, the method for calculating the number of the eggs 3 in one row comprises the following steps: when Xn is more than N, the rounding operation of 3 numbers of the eggs is as
And when Xn is less than or equal to N, the number of the eggs 3 is 1, and the total number of the eggs 3 in one row in the conveyor belt 1 is obtained by summing all the 3 numbers of the eggs corresponding to X1-Xn.
Further, the total number of eggs 3 in each row is accumulated and summed to obtain the total number of eggs 3 on the conveyor belt 1 passing through the infrared light source. The conveyor belt 1 automatically divides the eggs 3 into a plurality of rows, the number of each row is uncertain, the number of each row is calculated through the scanning counting of the infrared sensors 2, and the number of all the eggs 3 passing through the infrared sensors 2 can be calculated through the summation of the number of each row.
Further, the shielding length is the sum of the distances between the lasers formed after the infrared light source is shielded by the eggs 3 along the width direction of the conveyor belt 1. Because the irradiation of light is certain regional, and the motion of egg 3 is continuous, this just makes the signal that infrared sensor 2 received not a straight line shelter from the distance, here, we choose to shelter from the vertical direction of length along egg 3 motion, and the longest length of sheltering from when being in infrared light source setting direction under is the length of sheltering from that the calculation needs, because the grid fretwork design of conveyer belt 1 for egg 3 is fixed on conveyer belt 1, therefore its longest distance of sheltering from is located just on two adjacent bracing piece center lines of symmetry.
Further, the conveyor belt 1 is a grid-type conveyor belt, and comprises a plurality of mutually parallel support rods and a conveying chain for connecting the support rods, wherein two ends of each support rod are fixed on the conveying chain. Because egg 3 itself is the approximate globular structure characteristics, sets up many grid structure that the bracing piece supported with conveyer belt 1 for spherical egg 3 can form self-centering's effect between two bracing pieces, therefore makes egg 3 can be more stable realize the transportation operation on conveyer belt 1, and can not produce the condition that rolls and break away from conveyer belt 1. The conveying chain is used for fixing the supporting rods to enable the adjacent supporting rods to be equidistant and parallel, and on the other hand, under the condition that the conveying belt 1 needs to move, the end part of the conveying belt 1 can be matched with the gear to form a circulating belt capable of driving the conveying motor.
Further, the distance between two adjacent support rods is smaller than the minimum length of the egg 3. The grid interval needs to set up based on the maximum length and the minimum length of egg 3 for two adjacent bracing pieces can support an egg 3 of placing with the optional position just, therefore the grid interval need be greater than 3 minimum length of egg in order to avoid egg 3 to drop from the space between the grid, can not the undersize lead to every egg 3 to occupy the distance that length surpassed two spaces and lead to the count repetition simultaneously.
The utility model provides a quick counting assembly of egg, is including being used for displaying the conveyer belt 1 of waiting to check egg 3, being used for discerning the infrared sensor 2 of egg 3 and being used for calculating the treater of 3 quantity of egg, and infrared sensor 2 is fixed in conveyer belt 1 top, and infrared sensor 2 counts through scanning continuous motion's egg 3, and the treater is used for carrying out the method that realizes the quick count of egg 3. The eggs 3 on the whole conveyor belt 1 are driven to continuously pass through the infrared sensor 2 by the movement of the conveyor belt 1, so that the number of the eggs 3 displayed on the conveyor belt 1 passing through the scanning interval of the infrared sensor 2 is calculated. The treater is connected with 2 signal connections of infrared sensor, constantly discerns through infrared sensor 2 and is located the egg 3 that the band is disorderly placed on conveyer belt 1, counts the 2 signal of infrared sensor who receives through the treater and handles the egg 3 quantity that obtains exhibiting on every conveyer belt 1 clearance, and the quantity of all eggs 3 behind infrared sensor 2 is solved to the accumulative algorithm that the rethread treater was built-in.

Eggs in each chicken house are collected on the egg collecting chain, and the infrared sensor 2 calculates the egg yield of each chicken house by scanning the eggs on the egg collecting chain. The number of all eggs 3 displayed on the conveyor belt 1 is counted by pushing the infrared sensor 2, which is slidably attached above the conveyor belt 1, from one end of the conveyor belt 1 to the other.
