DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1-8 , the present invention provides a technical solution:

[0047] Embodiment 1:

[0048] A sampling-based feed quality detection device for aquaculture, the device mainly consists of a bracket 1, a conveyor belt 2, a support frame 3, a sampling mechanism, a sample transfer mechanism, a detection mechanism and a waste collection box 7.

[0049] The bracket 1 plays a vital role as a solid basic support structure for the entire device. The bracket 1 is usually made of high-strength metal materials, such as steel, to ensure that it can withstand the weight of the entire device and various forces during operation. A plurality of rollers are installed on the conveyor belt 2, which are connected to the bracket 1 through bearings so that the conveyor belt 2 can run smoothly. The conveyor belt 2 is generally made of wear-resistant rubber material and is fixed to the bracket 1 by bolts or rivets, etc., and is used to transport the feed to be tested. The feed can be stably transported forward on the conveyor belt 2, which provides convenience for the subsequent detection process.

[0050] The support frame 3 is also fixed on the bracket 1 by welding, bolt connection, etc. The support frame 3 is usually built of solid metal profiles, providing a stable installation platform for the sampling mechanism, the sample transfer mechanism and the detection mechanism. The design and installation position of the support frame 3 are carefully considered to ensure that the various mechanisms can work in coordination and efficiently complete the feed quality detection task.

[0051] The sampling mechanism includes a first crossbar 401 fixed on the support frame 3. The first crossbar 401 can be made of high-strength metal pipes and is firmly fixed to the support frame 3 by welding or bolting. A first rod frame 402 is installed on the first crossbar 401. The first rod frame 402 is usually made of metal plates and is fixed to the first crossbar 401 by bolts or welding. A first connecting rod 403 is fixed on the first rod frame 402. The first connecting rod 403 can be a solid metal rod and is connected to the first rod frame 402 by welding or threading to ensure the firmness of the connection. The end of the first connecting rod 403 is fixedly provided with a material removal column 404. The material removal column 404 is generally made of wear-resistant metal material and is fixed to the end of the first connecting rod 403 by welding or threading. At the same time, a telescopic cylinder 405 is also fixed on the first crossbar 401. The telescopic cylinder 405 can be a hydraulic telescopic cylinder 405 or an electric telescopic cylinder 405, which is fixed to the first crossbar 401 by bolts or welding. The movable end of the telescopic cylinder 405 is connected to the first fixing frame 406 by means of threaded connection, pin connection, etc. The first fixing frame 406 is usually made of metal plate, and a sampling sleeve 407 is fixed at one end by welding or threaded connection. The sampling sleeve 407 can be made of stainless steel to ensure its durability and corrosion resistance, and the sampling sleeve 407 is sleeved on the outside of the material withdrawal column 404, and the matching accuracy between the two is high to ensure the smooth progress of the sampling process.

[0052] The sample shifting mechanism includes a second fixed frame 501 fixed on the support frame 3. The second fixed frame 501 is also made of metal material and is fixed on the support frame 3 by welding or bolting. A first fixed sleeve 502 is installed on the second fixed frame 501. The first fixed sleeve 502 can be a metal sleeve and is fixed to the second fixed frame 501 by bolts or welding. The first servo 503 is fixed in the first fixed sleeve 502 by interference fit, bolt connection, etc. The second fixed sleeve 504 is connected to the rotating shaft of the first servo 503 by key connection, coupling, etc. The second fixed sleeve 504 is also a metal sleeve and is fixed to the second servo 505 by bolts or welding. The rotating shafts of the first servo 503 and the second servo 505 are arranged vertically. This design enables the sample shifting mechanism to rotate flexibly in two directions. A sample transfer rod 506 is fixed to the rotating shaft of the second steering gear 505 by welding, thread connection, etc. The sample transfer rod 506 is generally made of metal material, and a sample transfer tray 507 is eccentrically fixed to one end of the sample transfer rod 506. The sample transfer tray 507 can be made of plastic or metal, and is fixed to the sample transfer rod 506 by bolts or welding, and is used to receive the feed sample sent by the sampling mechanism.

[0053] The detection mechanism includes a connecting column 601 fixed to the support frame 3. The connecting column 601 is usually welded from a metal profile and fixed to the support frame 3 by welding or bolting. A detector 602 is installed on the connecting column 601 by bolts or slots. The detector 602 is one of the core components of the entire detection device, and it can detect various quality indicators of the feed in the sample transfer tray 507, such as nutritional component analysis, harmful substance detection, etc.

[0054] A waste collection box 7 is fixedly provided at a position of the bracket 1 on one side of the transmission belt by welding, bolt connection, etc. The waste collection box 7 is generally made of plastic or metal material and is used to collect feed samples after testing for subsequent processing.

[0055] During operation, the feed to be tested is placed on the conveyor belt 2. The conveyor belt 2 is supported by the bracket 1 and the rollers are driven by the motor to rotate and continuously run to continuously transport the feed forward. When the feed passes under the support frame 3, the sampling mechanism starts to work. Under the instruction of the control system, the telescopic cylinder 405 drives the sampling sleeve 407 to descend. Since the sampling sleeve 407 is located above the feed on the conveyor belt 2, as the telescopic cylinder 405 descends, the sampling sleeve 407 will gradually insert into the feed on the conveyor belt 2. Because the feed is in a viscous state and has a certain degree of adhesion, when the telescopic cylinder 405 rises, part of the feed will be retained in the sampling sleeve 407 due to the viscosity.

[0056] Then, when the telescopic cylinder 405 rises so that part of the feed is retained in the sampling sleeve 407, the sample transfer mechanism is started. The first steering gear 503 rotates ninety degrees under the control of the control system. Since the first steering gear 503 is installed in the first fixed sleeve 502 on the second fixed frame 501, its rotation will drive the second fixed sleeve 504 connected to the rotating shaft to rotate. The second fixed sleeve 504 drives the second steering gear 505 fixed therein and the sample transfer rod 506 and the sample transfer tray 507 connected to the rotating shaft of the second steering gear 505 to move to the bottom of the sampling sleeve 407. At this time, as the telescopic cylinder 405 continues to rise, under the action of the material withdrawal column 404, the feed in the sampling sleeve 407 is pushed out. Since the sample transfer tray 507 is just located below the sampling sleeve 407, the feed will accurately fall into the sample transfer tray 507.

[0057] Then, the first steering gear 503 rotates in the opposite direction by 90 degrees, and drives the sample transfer tray 507 to move to the bottom of the detection mechanism again. The detector 602 of the detection mechanism is fixed on the support frame 3 through the connecting column 601, and the position is stable. At this time, the detector 602 can detect the feed in the sample transfer tray 507. The detector 602 detects the quality of the feed through various sensors and analysis equipment, and the detection data can reflect the quality indicators such as the nutritional components and harmful substance content of the feed.

[0058] When the detection mechanism has finished detecting the feed, in order to clean the sample transfer tray 507 for the next detection, the second steering gear 505 rotates 180 degrees. Since the second steering gear 505 is fixed in the second fixing sleeve 504, its rotation drives the sample transfer rod 506 and the sample transfer tray 507 eccentrically fixed to one end of the sample transfer rod 506 to rotate. In this way, the detected feed on the sample transfer tray 507 will be dumped into the waste collection box 7.

[0059] This completes the entire process of feed quality testing. During the entire process, the various components work closely together, and through precise control and coordinated actions, efficient and accurate feed quality testing is achieved.

[0060] Embodiment 2:

[0061] In this embodiment, the bracket 1 plays a key supporting and connecting role. First, the air pump 801 and the first pipe rack 802 are fixedly arranged on the bracket 1 by bolting or welding. The first pipe rack 802 can be welded or clamped to firmly fix the pipeline 901. The pipeline 901 and the air pump 801 are fixedly connected by a sealing joint.

[0062] After the second steering gear 505 completes the turning action to dump the feed, the air pump 801 is powered on. At this time, the airflow generated by the air pump 801 is transported to the exhaust plate 902 through the pipeline 901. The exhaust plate 902 is also fixedly connected to the exhaust end of the pipeline 901 through a sealing joint. A plurality of exhaust pipes are provided on the exhaust plate 902, and the airflow is blown out from these exhaust pipes toward the sample transfer tray 507. When the airflow blows toward the sample transfer tray 507, the residual feed in the sample transfer tray 507 can be cleaned to prevent the residual feed from affecting subsequent operations.

[0063] A connecting frame 1001 is fixedly provided at the position of the bracket 1 at one end of the conveyor belt 2 by welding or bolt connection. A collection box 1002 is also fixedly provided at the bottom of the connecting frame 1001 by welding or bolt connection. The collection box 1002 is used to collect feed cleaned from the conveyor belt 2 and feed that may fall during the conveying process.

[0064] A brush plate 1101 is fixedly provided on the connecting frame 1001 by bolting or welding. A plurality of bristles 1102 are fixedly provided on the brush plate 1101, and the bristles 1102 are closely fitted to the conveyor belt 2. During the operation of the conveyor belt 2, the bristles 1102 can clean the surface of the conveyor belt 2, further clean the residual feed on the conveyor belt 2, and ensure the cleanliness of the conveyor belt 2.

[0065] The bracket 1 is also fixed with a controller 12 and a display 13 by bolting or welding. The controller 12 is used to control the operation of the entire device, and the display 13 can display the operation status, parameters and other information of the device.

[0066] In addition, a column 1401 is fixedly provided on the bracket 1 by welding or bolting. A feed hopper 1402 is fixedly provided on the column 1401 by welding or bolting. The bottom of the feed hopper 1402 is open and does not contact the conveyor belt 2, maintaining a certain gap. When the feed is placed in the feed hopper 1402 and the conveyor belt 2 rotates, the feed will be conveyed out from the bottom of the feed hopper 1402. Since the feed passes through the bottom of the feed hopper 1402, it will be subject to certain restrictions and sorting, so that it is laid flat on the conveyor belt 2 in a flat state. Such a design enables the sampling mechanism to complete the sampling work more smoothly, ensuring the accuracy and reliability of the sampling.

[0067] Working principle: Feeding stage: put the feed to be tested into the feed hopper 1402, and when the conveyor belt 2 rotates, the feed will be conveyed out from the bottom of the feed hopper 1402. Since the bottom of the feed hopper 1402 is open and does not contact the conveyor belt 2, the feed will be flattened on the conveyor belt 2 after passing through the bottom of the feed hopper 1402, preparing for the smooth sampling of the sampling mechanism.

[0068] Sampling stage: the telescopic cylinder 405 of the sampling mechanism drives the sampling sleeve 407 to descend, and the sampling sleeve 407 is inserted into the feed on the conveyor belt 2. Since the feed is in a viscous state, when the telescopic cylinder 405 rises, part of the feed will remain in the sampling sleeve 407. This is because the special design of the sampling sleeve 407 and the physical properties of the feed make it possible to effectively obtain a certain amount of feed samples during the sampling process.

[0069] Sample transfer stage: When the telescopic cylinder 405 rises and part of the feed is retained in the sampling sleeve 407, the sample transfer mechanism starts to work. The first steering gear 503 rotates 90 degrees, driving the second steering gear 505 and the sample transfer tray 507 to move to the bottom of the sampling sleeve 407. As the telescopic cylinder 405 continues to rise, the feed in the sampling sleeve 407 is pushed out and falls into the sample transfer tray 507 under the action of the material return column 404. The material return column 404 here plays a role in assisting the push-out of the feed, ensuring that the feed can accurately fall into the sample transfer tray 507.

[0070] Detection stage: The first steering gear 503 rotates 90 degrees in the opposite direction, driving the sample transfer tray 507 to move to the bottom of the detection mechanism. At this time, the detector 602 of the detection mechanism detects the feed in the sample transfer tray 507. The detection mechanism is fixed to the support frame 3 through the connecting column 601, and can stably detect various quality indicators of the feed. The detection results can be processed by the controller 12 and displayed on the display 13, which is convenient for the operator to view and analyze.

[0071] Waste treatment stage: When the testing mechanism has finished testing the feed, the second steering gear 505 rotates 180 degrees, driving the sample transfer rod 506 and the eccentric sample transfer tray 507 to rotate, and dumping the tested feed into the waste collection box 7. In this way, the sample transfer tray 507 can be cleaned in time to prepare for the next sampling and testing.

[0072] Residue cleaning stage: After the second steering gear 505 turns over to dump the feed, the air pump 801 is powered on to blow air into the sample transfer tray 507 through the pipe 901 on the first pipe rack 802. The exhaust plate 902 connected to the exhaust end of the pipe 901 is provided with a plurality of exhaust pipes, which can evenly blow air into the sample transfer tray 507 to clean the residual feed in the sample transfer tray 507. Ensure that the sample transfer tray 507 is clean and tidy to prevent residual feed from affecting the next test result.

[0073] Aggregation and conveyor belt 2 cleaning stage: During the entire detection process, the conveyor belt 2 continues to operate and continuously transports the feed. The feed on the conveyor belt 2 is finally transported to the collection box 1002 at the bottom of the connecting frame 1001 for collection. At the same time, the brush plate 1101 on the connecting frame 1001 and the bristles 1102 thereon fit with the conveyor belt 2, which can clean the conveyor belt 2, remove the residual feed and impurities on the conveyor belt 2, keep the conveyor belt 2 clean, and provide a good working environment for the next feed transportation and detection.

[0074] One method,

[0075] S1: Put the feed to be tested into the feed hopper 1402. The feed is conveyed out from the bottom of the feed hopper 1402 under the rotation of the conveyor belt 2 and laid flat on the conveyor belt 2.

[0076] S2: Start the device, the telescopic cylinder 405 of the sampling mechanism drives the sampling sleeve 407 to descend and insert into the feed on the conveyor belt 2. Since the feed is in a viscous state, part of the feed is retained in the sampling sleeve 407 when the telescopic cylinder 405 rises;

[0077] S3: Then, the first steering gear 503 of the sample transfer mechanism rotates 90 degrees, driving the second steering gear 505 and the sample transfer tray 507 to move below the sampling sleeve 407, and the telescopic cylinder 405 continues to rise. Under the action of the material return column 404, the feed in the sampling sleeve 407 is pushed out and falls into the sample transfer tray 507;

[0078] S4: Then, the first steering gear 503 rotates in the opposite direction by 90 degrees, driving the sample transfer tray 507 to move to the bottom of the detection mechanism, and the detector 602 of the detection mechanism detects the feed in the sample transfer tray 507, and the detection data can be displayed on the display 13;

[0079] S5: After the test is completed, the second steering gear 505 rotates 180 degrees, driving the sample transfer rod 506 and the eccentric sample transfer tray 507 to rotate, and dumping the tested feed into the waste collection box 7;

[0080] S6: Subsequently, the air pump 801 is powered on to blow air into the sample transfer tray 507 through the pipe 901 on the first pipe rack 802 and a plurality of exhaust pipes on the exhaust plate 902 at the exhaust end of the pipe 901, so as to clean the residual feed in the sample transfer tray 507;

[0081] S7: The conveyor belt 2 keeps running, and the feed on the conveyor belt 2 is finally conveyed to the collecting box 1002 at the bottom of the connecting frame 1001 for collection; at the same time, the brush plate 1101 on the connecting frame 1001 and the bristles 1102 thereon can clean the conveyor belt 2 to keep the conveyor belt 2 clean.

[0082] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
