[0041] The embodiments of the present application will be described in detail below with the accompanying drawings and examples, so that the realization process of how to apply technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

[0042] Example 1

[0043] The existing drum-type egg screening machine is prone to cause the eggs to fail to effectively reach the required screening area due to slow rotation speed, thereby causing the eggs to be blocked and the screening efficiency to be low. Figures 1-9 As shown in the figure, the present embodiment provides an egg size sorting device, which comprises a main transmission system 1 for multi-stage screening according to the size of the eggs, three branch transmission systems 2 for grading transmission of the eggs are arranged below the side of the main transmission system 1, the branch transmission system 2 selects a transmission belt on the roller shaft driven by a motor to transport the eggs, and in order to reduce the pressure of the eggs falling from the main transmission system 1 to the branch transmission system 2, the transmission belt on the branch transmission system 2 can be made of soft and elastic material, such as rubber material;

[0044] The above-mentioned main transmission system 1 is externally provided with an oil tank part 3 filled with food-grade mineral oil, which is used for spraying food-grade mineral oil on the surface of the eggs, and the shelf life of the sprayed eggs is longer;

[0045] The above-mentioned main transmission system 1 comprises a bearing frame 101 placed on the ground, four groups of transmission members 102 are installed on the top of the bearing frame 101, the transmission member comprises a motor, and then the motor drives a plurality of roller shafts to drive the conveying belt to run and transport the eggs, from back to front, the spacing between adjacent transmission members 102 gradually increases, and the spacing between adjacent transmission members 102 is provided with a dredging member 103, the transmission member 102 and the dredging member 103 cooperate to form four egg screening areas, and the surface of the four groups of transmission members 102 is fixedly installed with a plurality of limiting strips 104, the limiting strips 104 are mainly used for dividing the space on the transmission member 102, reducing the probability of collision between the eggs, and improving the transportation safety of the eggs;

[0046] In order to solve the problem of egg blockage, the present application uses the dredging member 103 to solve it, wherein the dredging member 103 comprises a steering motor 1031 fixed in the inner cavity of the side wall of the bearing frame 101, the output end of the steering motor 1031 is fixedly installed with a steering rod 1032 located in the spacing between adjacent transmission members 102, the outer part of the steering rod 1032 is fixedly installed with a plurality of blades 1033 for pushing the eggs to move, the surface of the blade 1033 can be provided with an elastic rubber layer, and at the same time, corrugated, point and other designs for increasing the anti-skid can also be provided, thereby improving the friction coefficient of the eggs after contacting with the blade 1033 and improving the stability of the eggs on the blade 1033;

[0047] The above-mentioned main transmission system 1 is divided into four egg screening areas by three groups of dredging members 103 and four groups of transmission members 102, which specifically comprises the following several egg size grades:

[0048] The first level: the first group of guiding members 103 and the first transmission member 102 are adjusted to a range of 35-37mm, and the target egg level is S, mainly less than 50g, so the first level is the first egg screening area on the main transmission system 1;

[0049] The second level: the second group of guiding members 103 and the second transmission member 102 are adjusted to a range of 38-40mm, and the target egg level is M, mainly 50-60g, so the screening area is the second screening area on the main transmission system 1;

[0050] The third level: the third group of guiding members 103 and the third transmission member 102 are adjusted to a range of 41-43mm, and the target egg level is L, mainly 60-68g, so the screening area is the third screening area on the main transmission system 1;

[0051] The fourth level: the fourth transmission member 102 directly transports and collects, and the target level is greater than or equal to 68g, so the egg of this level is directly conveyed on the main transmission system 1;

[0052] The three branch transmission systems 2 correspond to the first three levels of egg screening areas respectively;

[0053] In order to solve the problem of blocking in the egg screening process, the main transmission system 1 is used to solve the problem. When the eggs to be screened are placed on the first transmission member 102 of the main transmission system 1, the eggs will not be stacked on the transmission member 102 due to the limiting strip 104 arranged on the surface of the transmission member 102. When the first transmission member 102 transports the eggs to the position of the first guiding member 103, the steering motor 1031 on the guiding member 103 is started to drive the steering rod 1032 to rotate. The rotating steering rod 1032 automatically drives the plurality of blades 1033 to rotate, and the rotating blades 1033 push the eggs that do not meet the current screening area to the next transmission member 102. Since the guiding member 103 is always in a rotating state, the eggs are continuously driven, which avoids the blocking of the eggs and improves the efficiency of the egg screening,

[0054] Since the maximum diameter of the first guiding member 103 and the distance between the first transmission member 102 belong to the first level of screening eggs, the eggs that meet the size will fall onto the corresponding branch transmission system 2, and the subsequent eggs will be screened when transported on the main transmission system 1;

[0055] It should be noted that after the eggs enter the screening position, one of the blades 1033 on the dredging member 103 and the top of the conveying belt on the conveying member 102 need to be in a horizontal state, so as to ensure the accuracy of the egg screening, and avoid that the qualified eggs cannot pass through the current screening area smoothly when the blade 1033 is in an inclined state.

[0056] Embodiment 2

[0057] On the basis of embodiment 1, in order to solve the problems of slow egg conveying speed and easy crushing of eggs due to insufficient pushing force during egg conveying, as shown in Figures 1-2 、 Figures 4-5 、 Figure 7 The top of the main conveying system 1 is provided with three groups of dredging assemblies 4, which are used to assist the movement of the screened eggs on the main conveying system 1, so as to avoid the squeezing and blocking of the eggs.

[0058] The above-mentioned dredging assembly 4 includes two bearing plates 401 fixed on the top of the main conveying system 1, which are oppositely arranged. The top of each bearing plate 401 is provided with a placing groove 402. A drive motor 405 is installed in the inner cavity of each placing groove 402. The output shaft of the drive motor 405 is fixed with a drive gear 403. The drive motor 405 is used to drive the drive gear 403 to rotate, so as to drive the smearing member 404 to rotate, thereby smearing the surface of the eggs.

[0059] The drive gear 403 is engaged with the smearing member 404 installed in the inner part of the two placing grooves 402. The smearing member 404 can be directly manually disassembled, so it can be conveniently replaced after wear. The bottom of the placing groove 402 is connected with the inner cavity of the bearing plate 401, so that the drive gear 403 can drive the transmission gear 4042 to rotate.

[0060] The above-mentioned smearing member 404 includes a rotating rod 4041 placed on the two placing grooves 402. The two ends of the rotating rod 4041 are fixedly installed with a transmission gear 4042 engaged with the corresponding drive gear 403. The transmission gear 4042 needs to be aligned with the inner cavity of the placing groove 402. The middle part of the rotating rod 4041 is fixedly installed with a retaining wheel 4044. A plurality of groups of brushes 4043 are fixedly installed on the surface of the retaining wheel 4044 in a ring shape. The surface of the brush 4043 directly contacts the surface of the egg, thereby playing a role in pushing the egg.

[0061] In order to solve the problem of low efficiency of egg screening, the application uses the dredging assembly 4 to solve it. When the main conveying system 1 sorts the eggs by size, the dredging assembly 4 is started synchronously. At this time, the power drives the driving motor 405 to operate. The operating driving motor 405 drives the driving gear 403 to rotate. The rotating driving gear 403 can mesh and rotate with the transmission gear 4042 outside the rotating rod 4041 of the smearing part 404. The transmission gear 4042 driven by the driving force drives the rotating rod 4041 to rotate in the inner cavity of the groove 402 on the bearing plate 401. The rotating rod 4041 drives the several groups of brushes 4043 outside the retaining wheel 4044 to rotate synchronously. Since each dredging assembly 4 is arranged at the top of the corresponding screening area on the main conveying system 1, the brushes 4043 can contact the surface of the eggs when the main conveying system 1 screens the eggs. At this time, the eggs will be pushed by external pressure. The eggs that meet the screening standards will fall into the top of the branch conveying system 2 at the bottom of the screening area of the main conveying system 1. Otherwise, the eggs that do not meet the current screening area will also be pushed by the driving force, and then accelerate to leave the current screening area, thereby improving the screening efficiency of the size of the eggs, and avoiding the phenomenon of accumulation, extrusion and breakage caused by insufficient pushing force of the eggs.

[0062] Embodiment 3

[0063] On the basis of embodiment 2, the problem of short shelf life of eggs is solved. As shown in Figure 1 、 Figure 2 、 Figures 4-7 The oil tank part 3 includes an oil tank 301 filled with food-grade mineral oil at one end of the main conveying system 1. The top and bottom of the oil tank 301 are provided with an on-off switch, respectively for oil injection and oil discharge. The oil tank 301 is fixedly installed with an oil pump 302 outside. The input end of the oil pump 302 is fixedly installed with an oil extraction pipe 304 extending in the inner cavity of the oil tank 301. The oil pump 302 extracts the food-grade mineral oil in the oil tank 301 through the oil extraction pipe 304. The output end of the oil pump 302 is fixedly installed with a spray pipe 303 extending to the top of the main conveying system 1. The spray pipe 303 is used to spray the food-grade mineral oil directly on the surface of the eggs.

[0064] In order to solve the problem of short preservation period of eggs, the application uses the oil tank part 5 to solve it. When the eggs are placed on the main conveying system 1, the oil pump 302 is started. At this time, the oil pump 302 can transmit the food-grade mineral oil in the oil tank 301 to the spray pipe 303 through the oil extraction pipe 304. At this time, the spray pipe 303 sprays the food-grade mineral oil on the surface of the eggs. In this way, an airtight barrier can be formed on the surface of the eggs to block the exchange of air and moisture, thereby prolonging the shelf life of the eggs.

[0065] Meanwhile, the surface of the eggs is sprayed with food-grade mineral oil, and as the eggs roll on the main conveying system 1 and the branch conveying system 2, the food-grade mineral oil on the surface of the eggs is also applied to the surface of the main conveying system 1 and the branch conveying system 2, so that when the main conveying system 1 and the branch conveying system 2 come into contact with the surface of the eggs, the friction coefficient can be reduced, the eggshell breaking situation is reduced, and the food-grade mineral oil applied to the main conveying system 1 and the branch conveying system 2 also achieves the advantages of corrosion prevention and the like, improving the service life of the main conveying system 1 and the branch conveying system 2.

[0066] Finally, the unblocking assembly 4 on the main conveying system 1 also uses the rotating brush 4043 to roll in contact with the surface of the eggs and the main conveying system 1 and the branch conveying system 2, so that the function of applying the food-grade mineral oil to the surface of the main conveying system 1 and the branch conveying system 2 can be achieved, and the lubricating oil on the surface of the eggs and the main conveying system 1 and the branch conveying system 2 is applied more evenly, further improving the protection of the food-grade mineral oil on the eggs and the main conveying system 1 and the branch conveying system 2.

[0067] Embodiment 4

[0068] On the basis of embodiment 3, the interval of the egg size screening area is detected to avoid the problem of inaccurate egg screening. As shown in Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 The brush 4043 includes a fixed hair frame 40431 and food-grade bristles 40432 for assembly, and the inner cavity of the rotating rod 4041 is fixedly installed with a push rod motor 40433, and the output end of the push rod motor 40433 is fixed to the outer wall of the fixed hair frame 40431 by screws. The sizes of the corresponding fixed hair frames 40431 on the three unblocking assemblies 4 are different, and each fixed hair frame 40431 needs to correspond to the maximum width of the screening area of the corresponding grade;

[0069] In order to solve the problem of interval detection of the screening area, the brush 4043 is used to solve the problem. Since the transmission belt on the transmission member 102 may increase or decrease in interval after long-term use, the interval between the transmission member 102 and the dredging member 103 needs to be detected every certain period of time. At this time, the drive motor 405 on the unblocking assembly 4 is started, and then the drive motor 405 drives the corresponding brush 4043 installed with the push rod motor 40433 to move vertically downward. At this time, starting the push rod motor 40433 can drive the fixed hair frame 40431 to move towards the interval between the transmission member 102 and the dredging member 103 for detection. The specific detection steps are divided into two steps:

[0070] The first step is whether the hair fixing frame 40431 can pass through the gap between the transmission member 102 and the guiding member 103, and if it can pass, it means that the current position gap is not reduced;

[0071] The second step is to start the driving motor 405, and at this time, whether the hair fixing frame 40431 can be displaced (it needs to be noted that during the operation of this step, it needs to be ensured that one blade 1033 on the guiding member 103 and the top of the transmission member 102 are in a horizontally parallel state), and if it can be displaced, it means that the current position gap is expanded;

[0072] Through the detection of the two steps, it can be confirmed whether the gap between the transmission member 102 and the guiding member 103 at the current position changes, and at this time, the detection function of the gap between the transmission member 102 and the guiding member 103 is realized, and the egg size screening precision is ensured.
