AI Technical Summary
Existing egg counters with straps have low counting accuracy when detecting eggs due to vibration and size differences, and are prone to missed detections and false detections.
Using a TOF ranging sensor array in conjunction with a brush, the counting event is determined by detecting the cycle of the descent-return distance of the eggs. The side baffle and brush form an egg counting channel to ensure that the eggs pass under the sensor in a single row, eliminating blind spots in detection.
It significantly improves the accuracy of egg counting, avoids detection errors caused by rolling and stacking, and ensures the accuracy and reliability of counting results.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of egg counting technology, specifically an egg counter with an egg strap. Background Technology
[0002] In modern poultry farming, automated egg collection systems are widely used to achieve efficient egg collection and management. These systems utilize mechanical transmission to automatically transport eggs to the collection end via egg conveyors placed on both sides of the chicken cages, significantly improving collection efficiency compared to traditional manual egg collection. A counter installed at the end of the egg conveyor counts the transported eggs for production management and cost accounting.
[0003] However, during the transport of eggs via the egg conveyor belt, due to factors such as belt vibration and differences in egg size, eggs are prone to clustering and sticking together. This makes it difficult for the counter to effectively distinguish closely adjacent or overlapping eggs during detection, leading to frequent missed detections and false detections.
[0004] Therefore, it is necessary to propose an egg counter to solve the above problems. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] The purpose of this invention is to provide an egg counter with a coin to solve the problem of low counting accuracy of existing egg counters with a coin to a coin, as mentioned in the background section.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: an egg counter with an egg carrier, comprising a housing, wherein a plurality of TOF ranging sensors are fixedly connected in an array directly below the housing and perpendicular to the direction of egg transport, the detection ends of the TOF ranging sensors are vertically downward, and a brush is provided between two adjacent TOF ranging sensors, the brush being arranged along the perpendicular bisector of the line connecting the two TOF ranging sensors; a display screen is fixedly connected to the side wall of the housing, and both the display screen and the TOF ranging sensors are connected to the main control module.
[0009] Preferably, it also includes an egg strip, with side baffles on both sides of the egg strip, and the distance between the side baffles and the brush is adapted to the size of the poultry egg.
[0010] Preferably, the spacing between two adjacent TOF ranging sensors is adapted to the size of the egg.
[0011] Preferably, there are two TOF ranging sensors.
[0012] Preferably, one end of the brush is fixedly connected to a T-shaped brush holder, and the T-shaped brush holder is fixedly connected to the housing by screws.
[0013] Preferably, the length of the brush is greater than the length of the egg.
[0014] Preferably, the distance between the brush and the egg strip is smaller than the size of the egg.
[0015] Preferably, it also includes a communication module, which is connected to the main control module.
[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides an egg counter with an egg strap, which has the following beneficial effects:
[0018] 1. This egg counter uses a TOF distance sensor array and a brush to make the eggs pass through the sensor in a single row. The counting event is determined by the distance change cycle of "descent-return". At the same time, it eliminates the detection blind zone caused by rolling and stacking, and significantly improves the counting accuracy.
[0019] 2. This egg comes with an egg counter, and the brush uses a T-shaped brush holder that is rigidly connected to the shell to prevent the brush from tilting and ensure the combing effect of poultry eggs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Please see Figure 1-3As shown, an egg counter includes a housing 1. Several TOF distance sensors 7 are fixedly connected in an array directly below the housing 1, perpendicular to the direction of egg transport. The detection ends of the TOF distance sensors 7 are vertically downward. A brush 6 is provided between two adjacent TOF distance sensors 7, and the brush 6 is arranged along the perpendicular bisector of the line connecting the two TOF distance sensors 7. A display screen 2 is fixedly connected to the side wall of the housing 1. Both the display screen 2 and the TOF distance sensors 7 are connected to the main control module.
[0026] In use, the housing 1 is rigidly fixed above the egg conveyor belt 4 by a bracket, ensuring that multiple TOF distance sensors 7 are perpendicular to the conveying direction of the egg conveyor belt 4 and that the detection end of the TOF distance sensor 7 is perpendicular to the belt surface. When the eggs pass directly under the housing 1, the brush 6 combs and separates them, allowing them to pass under the TOF distance sensors 7 in a single row. The main control module collects the distance data of each TOF distance sensor 7 in real time. When a complete "descent-return" distance change cycle is detected (i.e., the process of an egg passing directly under the sensor), it is determined as a valid counting event. The main control module accumulates the counting results and displays the cumulative value in real time on the display screen 2.
[0027] Specifically, side baffles 5 are provided on both sides of the egg belt 4, and the distance between the side baffles 5 and the brushes 6 is adapted to the size of the eggs. By setting side baffles 5 on both sides of the egg belt 4, the eggs can be prevented from rolling off the egg belt 4. At the same time, the egg belt 4 and its adjacent brushes 6 cooperate to form an egg counting channel.
[0028] In one embodiment, there are two TOF ranging sensors 7.
[0029] To ensure that eggs pass directly beneath the TOF distance sensor 7 in a single file, the spacing between adjacent TOF distance sensors 7 is adapted to the size of the eggs. For example, when counting eggs, since the diameter of an egg is generally 40-50mm, by setting the spacing between the two TOF distance sensors 7 to 60mm, only one egg can pass directly beneath the TOF distance sensor 7 at a time, thus ensuring accurate identification.
[0030] Specifically, the length of brush 6 is greater than the length of the egg, and the distance between brush 6 and egg strip 4 is less than the size of the egg. With brush 6 in place, the center of the egg is always within the sensor's detection area, eliminating blind spots caused by rolling and ensuring counting accuracy.
[0031] In some embodiments, a T-shaped brush holder 9 is fixedly connected to one end of the brush 6, and the T-shaped brush holder 9 is fixedly connected to the housing 1 by screws. The T-shaped brush holder 9 supports and limits the brush 6, preventing the brush 6 from tilting and affecting the combing effect on poultry eggs.
[0032] In some embodiments, a communication module is also included, which is connected to the main control module. The communication module transmits the counting data and the device's unique address to the server, enabling the server to perform statistical analysis on the data from multiple devices. Specifically, two indicator lights 8 are provided on the outer side of the housing 1, used to indicate the device's operating status and communication status.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
