Description

Technical Field

[0001] The present application relates to the technical field of substance detection, and in particular to a device and method for detecting formula nutrients for high egg production in laying hens. Background Art

[0002] In recent years, with the increasing demand for the nutritional value of poultry eggs, improving the egg production and egg quality of laying hens has become an important research direction. Many studies have shown that the reasonable formulation of feed and the addition of high-quality nutrients can effectively improve the egg-laying performance of laying hens. However, different chicken breeds, growth stages, feeding environments and other factors have different requirements for nutrients, and it is difficult to ensure the optimal nutritional status of the flock by simply relying on traditional empirical formulas.

[0003] Therefore, in order to determine the nutrient requirements of different types of chickens for feed, by testing the content of nutrients such as protein, fat, carbohydrates, vitamins and minerals in the feed, we can understand the nutritional value of the feed more accurately, so as to customize suitable feed formulas for different breeds of chickens to ensure the healthy growth and high production performance of the flock.

[0004] When testing the protein and crude fiber in feed, the acid-base digestion method can be used. This method requires the feed to be dissolved in water. In order to accelerate the dissolution rate of the feed in water, the feed often needs to be crushed.

[0005] For example, the patent application with publication number CN117571408A discloses a device and method for detecting the amino acid content in feed, which achieves the advantage of crushing the feed by setting a sliding frame that can slide up and down in the processing box, and an extrusion plate with rollers slidably installed on both sides of the sliding frame. When the feed enters the processing box, the roller can be squeezed by the protrusion in the sliding frame through the downward movement of the sliding frame, thereby pushing the extrusion plate forward to fully compress and crush the feed. The combination of rollers and protrusions, and the protrusions gradually becoming larger from top to bottom, can ensure that the feed is fully crushed, thereby improving the accuracy and reliability of amino acid detection.

[0006] However, the following problems still exist when using the above-mentioned existing technology to crush feed: when the feed is crushed to a certain extent, the fluidity and volume density of the powder reach specific values, and the extrusion plate no longer moves. When pressure is applied subsequently, the feed can only be crushed by the static pressure of the extrusion plate, rather than by moving and squeezing, resulting in a decrease in the subsequent feed crushing effect.

[0007] Based on this, the above-mentioned method of feed crushing needs to be improved. Summary of the invention

DETAILED DESCRIPTION

[0042] The following is combined with Figures 1 to 10 This application is described in further detail.

[0043] The embodiment of the present application discloses a device and method for detecting a formula nutrient for high egg production in laying hens, which screens chicken feed so that the chicken feed is divided into different specifications according to diameter, and then applies dynamic pressure to the chicken feed so that the chicken feed is crushed more completely.

[0044] Example 1: Reference Figure 1 A device for detecting nutrient substances in formula for high egg production of laying hens comprises a crushing box 1 which is arranged through the box in its height direction, and a crushing mechanism 2 is arranged inside the crushing box 1.

[0045] Reference Figure 2 as well as Figure 3 The crushing mechanism 2 includes: a coarse crushing roller 21, which is symmetrically arranged along the width direction of the crushing box 1 and installed on the top of the crushing box 1 through a bearing, and is used to coarsely crush the chicken feed.

[0046] The fine grinding rollers 22 are symmetrically arranged along the width direction of the grinding box 1 and are installed at the bottom of the grinding box 1 through bearings, and are used to finely grind the chicken feed.

[0047] The screening component 23 is installed on the crushing box 1 and is used for screening the chicken feed.

[0048] The screening assembly 23 designed in the present invention can screen the chicken feed, so that the coarse chicken feed enters between the coarse crushing rollers 21 and is crushed, and the fine chicken feed enters between the fine crushing rollers 22 and is crushed. Then, the coarse crushing roller 21 and the fine crushing roller 22 cooperate with each other to perform multi-stage crushing on the chicken feed, thereby avoiding the possibility of chicken feeds of different diameters being piled up at the coarse crushing roller 21. At the same time, the coarse crushing roller 21 and the fine crushing roller 22 can always apply dynamic pressure to the chicken feed when crushing the chicken feed, thereby avoiding the situation where the chicken feed is only subjected to static pressure, resulting in the presence of uncrushed particles inside the chicken feed, which may lead to poor crushing effect.

[0049] Reference Figure 2 The screening component 23 includes: a screening box 231, which is arranged on the top of the crushing box 1, a feed inlet 232 is opened on the top of the screening box 231, and a discharge port is opened on the side of the screening box 231.

[0050] The screening frame 233 is obliquely arranged inside the screening box 231 , and a screening net 234 is arranged on the screening frame 233 .

[0051] The guide box 235 is arranged on the crushing box 1 , the top of the guide box 235 matches with the discharge port, and the side wall of the crushing box 1 is provided with a transition port matching with the bottom of the guide box 235 .

[0052] The material guide plate 236 is obliquely arranged inside the screening box 231 and at the bottom of the screening frame 233 , and the material guide plate 236 passes through the discharge port and cooperates with the guide box 235 .

[0053] Reference Figure 3 A guide plate 1 211 matched with the coarse crushing roller 21 and a guide plate 221 matched with the fine crushing roller 22 are arranged inside the crushing box 1. There are two guide plates 1 211 and two guide plates 221, which are symmetrically distributed along the width direction of the crushing box 1 and are used to guide the feeding of chicken feed.

[0054] The inclination direction of the screening frame 233 is opposite to that of the guide plate 236, and the guide plate 236 is located below the screening frame 233. During operation, the chicken feed is poured into the screening box 231 through the feed inlet 232 and falls on the screening net 234. At this time, due to the effect of gravity, the chicken feed rolls down along the screening frame 233 and the screening net 234. During the rolling process of the chicken feed on the screening net 234, the chicken feed (i.e., the coarse chicken feed) larger than the diameter of the screening net 234 continues to roll down along the screening net 234 and finally passes over the screening frame 233 and falls on the guide plate 1 211. The coarse chicken feed on the guide plate 1 211 falls on the coarse crushing roller 21, and the chicken feed (i.e., the fine chicken feed) smaller than the diameter of the screening net 234 falls on the guide plate 236 through the screening net 234.

[0055] The fine chicken feed that falls on the material guiding plate 236 drops onto the inside of the guiding box 235 via the material guiding plate 236. The fine chicken feed that enters the inside of the guiding box 235 drops onto the second guiding plate 221 after passing through the ferry. The coarse chicken feed on the second guiding plate 221 drops between the fine crushing rollers 22. Then, through the screening assembly 23, the specifications of the chicken feed can be distinguished and processed, avoiding the risk that the chicken feed completely pours between the coarse crushing rollers 21, resulting in excessive accumulation of chicken feed between the coarse crushing rollers 21 and being prone to blockage, and performing a pressure relief treatment.

[0056] Among them, the first guiding plate 211 and the second guiding plate 221 cooperate with each other to guide the coarse chicken feed and the fine chicken feed respectively, avoiding the leakage of chicken feed from the gaps between the coarse crushing roller 21 and the inner wall of the crushing box 1 and between the fine crushing roller 22 and the inner wall of the crushing box 1, which affects the subsequent crushing effect of the chicken feed.

[0057] Looking back Figure 2 , in order to further improve the screening effect of the screening assembly 23, the shaking frame 239 provided by the present invention can drive the screening frame 233 to reciprocate along the height direction of the screening box 231. Specifically, the shaft head of the coarse crushing roller 21 close to the guiding box 235 penetrates through the side wall of the crushing box 1, and a vibration part 237 is further provided on the screening box 231, including: a shaking cam 238, which is installed on the shaft head of the coarse crushing roller 21 penetrating through the side wall of the crushing box 1.

[0058] The shaking frame 239 is set as a U-shaped structure with an open bottom and is slidably arranged on the side wall at the feed port 232 of the screening box 231. The vertical section of the shaking frame 239 inside the screening box 231 is installed on the screening frame 233. A connecting rod is installed at the bottom of the vertical section of the shaking frame 239 outside the screening box 231, and the connecting rod abuts against the shaking cam 238.

[0059] During specific operation, when the corresponding coarse crushing roller 21 rotates, it drives the shaking cam 238 to rotate. When the long half-section of the shaking cam 238 drives the shaking frame 239 to move upward, the screening frame 233 moves upward synchronously. When the short half-section of the shaking cam 238 contacts the shaking frame 239, at this time, the screening frame 233 moves downward due to gravity. Therefore, during the rotation of the shaking cam 238, it cooperates with the shaking frame 239 to drive the shaking frame 239 to move up and down reciprocally. During the up and down reciprocating movement of the shaking frame 239, the screening net 234 is synchronously driven to move. During the up and down reciprocating movement of the screening net 234, the chicken feed on its surface can be screened, and then the chicken feed on the screening net 234 can be shaken evenly, avoiding the possibility that the upper surface part of the chicken feed does not contact the screening net 234 and is not screened, making the screening effect of the chicken feed better. At the same time, the chicken feed stuck in the mesh holes of the screening net 234 can be vibrated to ensure that the mesh holes of the screening net 234 are not blocked by the chicken feed, ensuring the screening effect of the screening net 234.

[0060] The diameter of the coarse crushing roller 21 is slightly smaller than the diameter of the fine crushing roller 22, and the minimum distance between the two coarse crushing rollers 21 is greater than the minimum distance between the two fine crushing rollers 22, so that the two coarse crushing rollers 21 cooperate with each other to crush the coarse chicken feed, and the two fine crushing rollers 22 cooperate with each other to crush the fine chicken feed. The coarse crushing roller 21 and the fine crushing roller 22 are driven by the existing driving motor to rotate simultaneously, and the two coarse crushing rollers 21 rotate in opposite directions, and the two fine crushing rollers 22 rotate in opposite directions. During the rotation of the coarse crushing rollers 21 in the same group, dynamic pressure can be applied to the coarse chicken feed, so that the coarse chicken feed can be squeezed and crushed, and the crushed chicken feed continues to fall downward.

[0061] Reference Figure 4 A plurality of annular grooves 212 are evenly formed on the coarse crushing roller 21 along its length direction, and a scraper 213 matching the annular grooves 212 is arranged on the inner wall of the crushing box 1 .

[0062] The annular groove 212 arranged on the circumferential surface of the coarse crushing roller 21 can increase the friction force on the surface of the coarse crushing roller 21, and then when crushing the coarse chicken feed, the coarse crushing roller 21 can rotate and transport the coarse chicken feed to the position where the spacing between the coarse crushing roller 21 is the smallest, so as to avoid relative sliding between the coarse chicken feed and the coarse crushing roller 21, so that the coarse crushing roller 21 can crush the coarse chicken feed, wherein the scraper 213 is provided with a sheet-like protrusion corresponding to the annular groove 212, and then during the rotation of the coarse crushing roller 21, the scraper 213 can scrape off the chicken feed adhered to the surface of the coarse crushing roller 21, and the sheet-like protrusion can scrape off the chicken feed clamped inside the annular groove 212, so as to avoid the chicken feed filling the annular groove 212 and affecting the friction force of the circumferential surface of the coarse crushing roller 21, and reduce the possibility of relative sliding of the chicken feed on the surface of the coarse crushing roller 21.

[0063] Reference Figure 5 Since the chicken feed contains moisture, the coarse crushing roller 21 may cause the extruded chicken feed to stick together after squeezing and crushing the coarse chicken feed. The extruded chicken feed has a cake-like structure. After the cake-like chicken feed falls on the fine crushing roller 22, it is too large to enter between the fine crushing rollers 22. The grinding plate 11 designed in the present invention can grind the coarsely crushed chicken feed during the reciprocating movement. Specifically, the grinding plates 11 symmetrically arranged along the width direction of the crushing box 1 are arranged inside the crushing box 1 and between the coarse crushing roller 21 and the fine crushing roller 22. The top of the grinding plates 11 is provided with rubber belts 12, and the end of the rubber belt 12 away from the corresponding grinding plate 11 is installed on the inner wall of the crushing box 1 on the corresponding side.

[0064] The back sides of the grinding plates 11 are symmetrically provided with makeshift grooves along their length directions, and moving blocks 13 are arranged inside the makeshift grooves. The moving blocks 13 are installed with elastic telescopic rods 14, and the telescopic ends of the elastic telescopic rods 14 are installed on the inner walls of the makeshift grooves. Elastic telescopic rods 2 15 corresponding to the makeshift grooves are installed on the inner walls of the crushing box 1, and the telescopic sections of the elastic telescopic rods 2 15 are connected to the moving blocks 13 inside the corresponding makeshift grooves.

[0065] The grinding range of the chicken feed by the grinding plate 11 is between the minimum spacing of the coarse grinding rollers 21 and the minimum spacing of the fine grinding rollers 22, that is, the chicken feed crushed by the coarse grinding rollers 21 can be crushed and ground for the second time between the grinding plates 11, and the chicken feed crushed and ground for the second time by the grinding plates 11 can fall between the fine grinding rollers 22 for further crushing, and the top opposite surface of the grinding plate 11 is provided with a guiding inclined surface.

[0066] During specific operation, the chicken feed crushed by the coarse crushing roller 21 falls between the grinding plates 11. At this time, the rubber belt 12 can limit the fallen chicken feed to prevent the chicken feed from falling into the gap between the grinding plate 11 and the inner wall of the crushing box 1, affecting the grinding effect of the grinding plate 11 on the chicken feed. At this time, the grinding plate 11 close to the guide box 235 is driven upward by external force, and the corresponding elastic telescopic rod 14 is stretched. The grinding plate 11 away from the guide box 235 is driven downward by external force, and the corresponding elastic telescopic rod 14 is compressed. When the grinding plate 11 moves a certain distance, the external force is removed at this time, and the grinding plate 11 close to the guide box 235 is reset and moved downward due to the elastic telescopic rod 14, and the grinding plate 11 away from the guide box 235 is also reset and moved upward due to the elastic telescopic rod 14. Repeat the above action, and then the two grinding plates 11 alternately reciprocate up and down and cooperate with the elastic telescopic rod 14, so that friction force in the up and down directions can be applied to the chicken feed, so that the chicken feed can be ground.

[0067] In order to improve the grinding effect of the grinding plates 11, forces in opposite directions can be applied to the grinding plates 11 during the up and down movement of the grinding plates 11, so that the spacing between the grinding plates 11 can be variable, and then the grinding plates 11 can move toward each other during the up and down reciprocating movement of the grinding plates 11 to squeeze the chicken feed during the grinding process. When the grinding plates 11 move toward each other for a distance, the external force is removed, and the elastic telescopic rod 15 resets the grinding plates 11, thereby further improving the grinding degree of the chicken feed between the grinding plates 11, and ensuring the effect of the crushing and grinding of the chicken feed.

[0068] The moving block 13 can ensure that the grinding plate 11 and the elastic telescopic rod 15 will not have a rigid collision during the up and down reciprocating movement of the grinding plate 11, thereby avoiding the elastic telescopic rod 15 from being rigidly broken, and the rubber belt 12 is elastic (that is, the length is variable) to ensure that the rubber belt 12 can always guide the chicken feed falling from the top during the up and down reciprocating movement of the grinding plate 11.

[0069] Reference Figure 6 A rack plate 111 is installed on the top of the grinding plate 11, and an incomplete gear 112 meshing with the rack plate 111 is installed on the coarse crushing roller 21.

[0070] A plurality of gear teeth are evenly arranged on the circumferential surface of the incomplete gear 112, and no gear teeth are arranged between adjacent gear teeth. Since the two coarse grinding rollers 21 rotate in opposite directions, at the starting position, the rack plate 111 far from the guide box 235 and the rack plate 111 close to the guide box 235 are in the same meshing position with the incomplete gear 112, so that the coarse grinding roller 21 can drive the grinding plate 11 to reciprocate up and down during the process of meshing with the incomplete gear 112 and the corresponding rack plate 111.

[0071] The meshing length between each gear tooth portion and the rack plate 111 is equal to the upward or downward length of the grinding plate 11 .

[0072] During specific operation, the pulley incomplete gear 112 rotates during the rotation of the coarse crushing roller 21. At this time, during the rotation of the incomplete gear 112 close to the guide box 235, the gear tooth portion and the corresponding rack plate 111 are engaged with each other, driving the corresponding grinding plate 11 to move up, and the corresponding elastic telescopic rod 14 is stretched. At the same time, during the rotation of the incomplete gear 112 far away from the guide box 235, the gear tooth portion and the corresponding rack plate 111 are engaged with each other, driving the corresponding grinding plate 11 to move down, and the corresponding elastic telescopic rod 14 is compressed.

[0073] When the gear tooth portion just moves out of the rack plate 111, the non-gear tooth portion of the incomplete gear 112 close to the guide box 235 cooperates with the rack plate 111, and the corresponding rack plate 111 is not subjected to force at this time. At this time, the corresponding elastic telescopic rod 14 resets and drives the grinding plate 11 to move downward, and the non-gear tooth portion of the incomplete gear 112 away from the guide box 235 cooperates with the rack plate 111, and the corresponding rack plate 111 is not subjected to force at this time. At this time, the corresponding elastic telescopic rod 14 resets and drives the grinding plate 11 to move upward.

[0074] By repeating the above-mentioned actions, the grinding plate 11 can move reciprocally up and down.

[0075] Reference Figure 7 as well as Figure 8A linkage rod 113 is slidably arranged on the side wall of the grinding plate 11, and the end of the linkage rod 113 away from the grinding plate 11 passes through the guide plate 221 on the corresponding side. An annular disk 114 is installed on the fine grinding roller 22, and a plurality of linkage protrusions 115 are evenly arranged on the side wall of the annular disk 114 along its circumference, and the end of the linkage rod 113 away from the grinding plate 11 abuts against the side wall of the annular disk 114.

[0076] During specific operation, the two fine grinding rollers 22 drive the annular disk 114 to rotate synchronously during rotation, and the annular disk 114 drives the linkage protrusion 115 to rotate synchronously during rotation. When the linkage protrusion 115 abuts against the linkage rod 113, the linkage rod 113 drives the grinding plate 11 to move toward each other synchronously during the movement toward each other. At this time, the elastic telescopic rod 15 is stretched, thereby shortening the distance between the two grinding plates 11 to extrude the chicken feed. When the linkage protrusion 115 passes over the corresponding linkage rod 113, the elastic telescopic rod 15 is reset and drives the grinding plate 11 to reset synchronously, and then the grinding plate 11 can be driven to move toward each other to extrude and crush the chicken feed during the reciprocating movement of the grinding plate 11 up and down.

[0077] The linkage rod 113 is slidably arranged on the side wall of the grinding plate 11 to ensure that the grinding plate 11 will not have a rigid collision with the linkage rod 113 during the up and down reciprocating movement.

[0078] The chicken feed ground by the grinding plate 11 falls between the fine grinding rollers 22 and is ground again to obtain completely ground chicken feed.

[0079] Example 2: Reference Fig. 9 On the basis of the first embodiment, two shaking frames 3 that fit each other and move back and forth are slidingly arranged at the bottom of the crushing box 1, and the shaking frames 3 correspond one to one with the fine crushing rollers 22, and a plurality of shaking rods 31 are evenly installed inside the shaking frame 3 along its width direction.

[0080] The shaking frames 3 are all equipped with elastic ropes 32, and one end of the elastic ropes 32 away from the corresponding shaking frames 3 is installed on the inner wall of the crushing box 1 on the corresponding side. The fine crushing rollers 22 are all equipped with toggle protrusions 33, and the shaking frames 3 are provided with toggle rods 34 corresponding to the toggle protrusions 33.

[0081] During specific operation, in the initial state, the fine grinding roller 22 rotates and drives the toggle rod 34 to move apart through the toggle protrusion 33. The elastic rope 32 is stretched during the movement of the two toggle rods 34. When the toggle protrusion 33 is separated from the toggle rod 34, the elastic rope 32 is reset to drive the two shaking frames 3 to reset. When the toggle protrusion 33 contacts the toggle rod 34 again and drives the toggle rod 34 to move, the above action is repeated, and then the toggle rod 34 moves back and forth and drives the shaking frame 3 to shake back and forth alternately during the reciprocating movement. During the reciprocating shaking of the shaking frame 3, the shaking rod 31 can be driven to shake and rub the crushed chicken feed, so that the chicken feed is in a uniform powder, thereby preventing the chicken feed crushed by the fine grinding roller 22 from being in a cake shape, which affects its subsequent dissolution efficiency.

[0082] Finally, refer to Fig.10 The present invention also provides a method for detecting nutrient substances in a formula for high egg production of laying hens, comprising the following steps: S1: pouring treatment, pouring chicken feed into the interior of a screening box 231 through a feed inlet 232 and dropping it on a screening net 234. At this time, due to the action of gravity, the chicken feed rolls down along the screening frame 233 and the screening net 234. During the rolling process of the chicken feed on the screening net 234, the chicken feed (i.e., coarse chicken feed) larger than the diameter of the screening net 234 continues to roll down along the screening net 234 and eventually passes over the screening frame 233 and drops onto a guide plate 211. The coarse chicken feed on the guide plate 211 drops onto a coarse crushing roller 21, and the chicken feed (i.e., fine chicken feed) smaller than the diameter of the screening net 234 drops onto a guide plate 236 through the screening net 234.

[0083] S2: Feed processing, the fine chicken feed falling on the guide plate 236 falls into the guide box 235 through the guide plate 236, and the fine chicken feed entering the guide box 235 falls onto the guide plate 221 through the transition port, and the coarse chicken feed on the guide plate 221 falls between the fine crushing rollers 22, and then the chicken feed can be processed according to its specifications through the screening component 23.

[0084] S3: Crushing process: the coarse chicken feed is ground by the coarse crushing roller 21 and the grinding plate 11, and then enters the fine crushing rollers 22 for secondary crushing. The fine chicken feed is crushed by the fine crushing rollers 22 and directly discharged.

[0085] S4: collecting and processing the crushed chicken feed at the bottom of the crushing box 1.
