Description

Technical Field

[0001] This invention relates to the field of biochemical sensor detection technology, specifically a chemical detection device for broiler feed components based on biochemical sensing. Background Technology

[0002] In broiler farming, the quality and nutritional composition of feed are core factors affecting the growth performance, health level, and ultimate economic benefits of broilers. Analyzing the composition of feed raw materials and finished products, such as the content of protein, fat, moisture, trace elements, and potential harmful substances, is a key step in achieving precise nutritional regulation, ensuring farming safety, and optimizing feeding costs. Biochemical sensing technology, as an advanced detection method, is widely used in the field of feed composition analysis due to its advantages such as rapid response, good selectivity, ease of automation, and on-site testing.

[0003] However, when applying biochemical sensors to raw feed samples, significant pretreatment challenges arise. In existing technologies, the typical pretreatment process for feed samples usually includes multiple independent and separate steps such as grinding, homogenization, centrifugation, or filtration and dehydration. These steps often rely on different specialized equipment such as grinders, centrifuges, filtration devices, and manual operation, resulting in problems such as cumbersome processes, complex operations, long processing times, susceptibility to cross-contamination of samples, large equipment footprint, and low overall analysis efficiency. The limitations of this step-by-step processing mode are even more pronounced in scenarios requiring rapid on-site screening or large-scale sample processing, making it difficult to meet the requirements of modern farms for timely and convenient testing.

[0004] To address these issues, we provide a chemical detection device based on biochemical sensing of broiler feed components. Summary of the Invention

The limiting component includes a limiting guide plate fixed to the inner wall of the main body of the device and a limiting guide rod fixed to the grinding head. The limiting guide rod is disposed through the limiting guide plate.

[0011] A chemical detection device for broiler feed components based on biochemical sensing, as described above: The linkage mechanism includes a driven shaft rotatably mounted on the main body of the device. The driven shaft is engaged with the main shaft through a one-way transmission mechanism. When the main shaft rotates in a first direction, it drives the driven shaft to rotate. When the main shaft rotates in a second direction opposite to the first direction, the driven shaft does not rotate. A wheel cylinder is rotatably mounted on the main body of the device. The wheel cylinder is engaged with the driven shaft through a first gear mechanism. When the driven shaft rotates, it drives the wheel cylinder to rotate. A lifting rod is fixed on the grinding head and movably inserted inside the wheel cylinder. The lifting rod is engaged with the wheel cylinder through a grooved roller structure. When the wheel cylinder rotates, it drives the lifting rod to move up and down.

[0012] A chemical detection device for broiler feed components based on biochemical sensing, as described above, includes a unidirectional transmission mechanism comprising a transmission disc rotatably mounted on the main body of the device and an active ratchet fixed on the main shaft. A pawl is hinged to the transmission disc and engages with the active ratchet. A clamping torsion spring is fixedly mounted on the transmission disc, clamping against one side of the pawl to apply a preload force to the active ratchet. The transmission disc and the driven shaft are connected via a second gear mechanism. Rotation of the transmission disc drives the driven shaft to rotate.

[0013] A chemical detection device for broiler feed components based on biochemical sensing, as described above: The first gear mechanism includes a driven gear fixedly mounted on a wheel cylinder and a driving gear fixedly mounted on a driven shaft, wherein the driven gear and the driving gear mesh with each other.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) This invention integrates key pretreatment steps such as grinding and homogenizing of feed samples and centrifugal dehydration with subsequent biochemical sensing and detection modules into one device. The main shaft is driven by a motor and controlled by a linkage mechanism. The entire process from solid feed to a clear liquid sample that can be tested can be completed automatically and continuously in the sample tank. The ground slurry can be directly separated into liquid and solid under centrifugal force through the filter holes on the sample tank. The clear liquid enters the detection area, realizing integrated operation of sample detection and greatly simplifying the process. (2) The present invention, through the cooperation of the main shaft, the one-way transmission mechanism and the linkage mechanism, can automatically switch the working mode of the device by relying only on the bidirectional rotation of the main shaft. When the motor drives the main shaft to rotate in the first direction, the linkage mechanism drives the grinding head to move up and down reciprocally under the constraint of the limiting component, and rotates and shears relative to the grinding disc fixed at the bottom of the sample tank, so as to achieve efficient grinding and homogenization. When the motor drives the main shaft to rotate in the opposite direction to the first direction, the one-way transmission mechanism disengages and the linkage mechanism stops moving, so that the grinding head remains stationary and raised. The main shaft directly drives the sample tank and the grinding disc to rotate at high speed to achieve centrifugal dehydration. This design realizes the automatic switching of grinding and centrifugation functions with a single power source. The structure is ingenious and reliable. (3) The integrated closed processing flow of the present invention is completed in the same sample container, eliminating the cumbersome sample transfer steps in the traditional step-by-step operation. It can not only shorten the pretreatment time, but also effectively avoid sample loss, cross-contamination and human error that may occur during the transfer process. The clear liquid separated by the filter hole has uniform composition, providing a stable and reliable sample for the biochemical sensor below, which significantly improves the repeatability and accuracy of the detection results. (4) Because the invention integrates the functions of driving, transmission, grinding, centrifugation and detection, the whole device has a compact structure. The layout of the motor, linkage mechanism, sample tank and biochemical sensor detector makes the equipment occupy a small area. All material operations can be completed through the feeding pipe and the drain valve, greatly simplifying the steps. The invention is very suitable for rapid screening in on-site environments such as farms and feed production workshops. It is also convenient for automated processing of batch samples in the laboratory. It has a wide range of applications. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Please see Figures 1-10 As an embodiment of the present invention, a chemical detection device for broiler feed components based on biochemical sensing includes a device body 1, a bracket 2 fixedly installed inside the device body 1, a sample container 3 rotatably installed on the bracket 2, a filter hole 7 opened on the sample container 3, and the sample container 3 is driven to rotate by a first driving mechanism. A grinding disc 27 is fixed to the bottom wall of the sample container 3. A grinding head 8 that can move up and down is provided on the inner side of the sample container 3. The grinding head 8 is used to cooperate with the grinding disc 27 to grind the feed in the container. The support 2 has a through hole 24, and the internal bottom wall of the main body 1 is fixedly installed with a biochemical sensor detector 25 for chemical detection of feed components. The first drive mechanism includes a main shaft 4 rotatably mounted on the main body 1 of the device, and a sample container 3 fixedly mounted on the main shaft 4; The grinding head 8 and the main shaft 4 are connected by a linkage mechanism. When the main shaft 4 rotates in the first direction, the linkage mechanism drives the grinding head 8 to move up and down, so that it can cooperate with the synchronously rotating grinding disc 27 to complete the grinding of the feed. When the main shaft 4 rotates in the second direction opposite to the first direction, the main shaft 4 drives the grinding disc 27 to rotate to centrifuge and dehydrate the feed, and during this process, the linkage mechanism keeps the grinding head 8 stationary.

[0030] In this embodiment, when it is necessary to process and test the feed sample, the feed to be tested and the required test solvent are added into the sample container 3 together. The drive device is started to drive the main shaft 4 to rotate in the first direction. The main shaft 4 drives the sample container 3 and the grinding disc 27 fixed to its inner bottom wall to rotate synchronously. At the same time, the main shaft 4 drives the grinding head 8 to move up and down inside the sample container 3 through the linkage mechanism. The up and down moving grinding head 8 and the rotating grinding disc 27 generate relative motion, which strongly shears and grinds the feed between the two, so that it is fully mixed and homogenized with the test solvent to form a uniform slurry. After homogenization, the drive device drives the main shaft 4 to rotate at a higher speed in a second direction opposite to the first direction. At this time, the linkage mechanism keeps the grinding head 8 stationary and in a raised state. The main shaft 4 drives the sample container 3 and the grinding disc 27 to rotate at high speed. Under the action of centrifugal force, the liquid components in the slurry in the sample container 3 are thrown out through the filter holes 7 opened on the side wall of the sample container 3, while the solid residue is trapped in the sample container 3, thereby realizing the liquid-solid separation of the slurry. The separated clear liquid flows down through the through holes 24 opened on the support 2 and is finally collected by the biochemical sensor detector 25 located on the bottom wall of the main body of the device 1 for component analysis, thus completing the integrated process from sample processing to detection.

[0031] As a further embodiment of the present invention, a feeding pipe 6 for adding materials into the sample container 3 and a drain valve 26 for discharging materials from the inside of the device body 1 are fixedly installed on the device body 1.

[0032] In this embodiment, the feeding pipe 6 facilitates the addition of a fixed amount of feed and detection solvent into the sample container 3, and the drain valve 26 is used to drain any waste liquid or cleaning liquid that may accumulate in the main body 1 of the device after the detection process is completed, so as to facilitate equipment cleaning and maintenance.

[0033] As a further embodiment of the present invention, a motor 5 is fixedly installed on the main body 1 of the device, and the output end of the motor 5 is connected to the main shaft 4 through a coupling to drive the main shaft 4 to rotate.

[0034] In this embodiment, the motor 5 is the core power source of the device. The motor 5 is electrically connected to an external power source and a controller through wires. The controller can control its start, stop, direction and speed change, providing power for the rotation of the sample container 3, the movement of the grinding head 8 and the entire processing flow.

[0035] As a further embodiment of the present invention, the filter holes 7 are uniformly opened in the middle region of the sample container 3 and located above the grinding disc 27.

[0036] In this embodiment, the filter hole 7 is located in the middle of the sample tank 3 and is higher than the grinding disc 27. This ensures that during the grinding stage, since the sample tank 3 rotates at a low speed and the slurry level is below the filter hole 7, it will not be thrown out through the filter hole 7. However, during the centrifugal separation stage, the sample tank 3 rotates at a high speed, and the slurry inside the sample tank 3 is thrown to the inner wall of the sample tank 3 by centrifugal force, and the liquid level will cover the filter hole 7. This allows the liquid to be effectively thrown out after being filtered through the filter hole 7 under the action of centrifugal force, while preventing solid residue from clogging the filter hole 7 during the grinding stage, thus ensuring separation efficiency and effect.

[0037] As a further embodiment of the present invention, the main body 1 of the device is provided with a limiting component for the grinding head 8 to move up and down. The limiting component includes a limiting guide plate 9 fixed to the inner wall of the main body 1 of the device and a limiting guide rod 10 fixed to the grinding head 8. The limiting guide rod 10 is disposed through the limiting guide plate 9.

[0038] In this embodiment, the cooperation between the limiting guide rod 10 and the limiting guide plate 9 restricts the grinding head 8 to reciprocate linearly along a preset vertical axis, preventing it from rotating circumferentially or shifting radially during operation. This ensures the accuracy and stability of the relative movement between the grinding head 8 and the grinding disc 27, thereby guaranteeing the grinding and mixing effect.

[0039] As a further embodiment of the present invention, the linkage mechanism includes a driven shaft 15 rotatably mounted on the main body 1 of the device. The driven shaft 15 is connected to the main shaft 4 through a one-way transmission mechanism. When the main shaft 4 rotates in a first direction, it drives the driven shaft 15 to rotate. When the main shaft 4 rotates in a second direction opposite to the first direction, the driven shaft 15 does not rotate. A wheel cylinder 18 is rotatably mounted on the main body 1 of the device. The wheel cylinder 18 is connected to the driven shaft 15 through a first gear mechanism. When the driven shaft 15 rotates, it drives the wheel cylinder 18 to rotate. A lifting rod 19 is fixed on the grinding head 8 and is movably inserted into the wheel cylinder 18. The lifting rod 19 is connected to the wheel cylinder 18 through a grooved roller structure. When the wheel cylinder 18 rotates, it drives the lifting rod 19 to move up and down.

[0040] In this embodiment, the linkage mechanism is the core of the switching of the grinding head 8's motion mode. When the main shaft 4 rotates in the first direction, it drives the driven shaft 15 to rotate through the one-way transmission mechanism, and then drives the wheel cylinder 18 to rotate through the first gear mechanism. The grooved roller structure on the inner wall of the wheel cylinder 18 converts the rotational motion into the up-and-down reciprocating motion of the lifting rod 19 and the grinding head 8 fixed thereto, which works in conjunction with the rotating grinding disc 27 for grinding. When the main shaft 4 rotates in the second direction, the one-way transmission mechanism disengages, and the driven shaft 15, wheel cylinder 18 and lifting rod 19 stop rotating, and the grinding head 8 stops. At this time, the power of the main shaft 4 is used to drive the sample tank 3 to rotate at high speed to centrifuge the feed. This design realizes the automatic and mechanical switching of two working modes under a single power source.

[0041] As a further embodiment of the present invention, the one-way transmission mechanism includes a transmission disk 11 rotatably mounted on the main body 1 of the device and a driving ratchet 12 fixed on the main shaft 4. A pawl 13 is hinged on the transmission disk 11 and engages with the driving ratchet 12. A clamping torsion spring 14 is fixedly mounted on the transmission disk 11 and clamps against one side of the pawl 13 so that the pawl 13 applies a preload force to the driving ratchet 12. The transmission disk 11 and the driven shaft 15 are engaged through a second gear mechanism. When the transmission disk 11 rotates, it drives the driven shaft 15 to rotate.

[0042] In this embodiment, when the main shaft 4 drives the active ratchet 12 to rotate in the first direction, under the action of the clamping torsion spring 14, the end of the pawl 13 engages in the tooth groove of the active ratchet 12, pushing the transmission disk 11 to rotate synchronously. The power can be transmitted to the driven shaft 15 through the second gear mechanism. When the main shaft 4 rotates in the second direction, the pawl 13 slides on the back of the teeth of the active ratchet 12 and cannot drive the transmission disk 11 to rotate. The power transmission is interrupted here, and the driven shaft 15 remains stationary. This mechanism ensures the unidirectionality of power transmission and is the key to realizing function switching.

[0043] As a further embodiment of the present invention, the first gear mechanism includes a driven gear 20 fixedly mounted on the wheel cylinder 18 and a driving gear 21 fixedly mounted on the driven shaft 15, wherein the driven gear 20 and the driving gear 21 mesh with each other.

[0044] In this embodiment, the driving gear 21 and the driven gear 20 constitute a first gear mechanism, which is used to transmit the rotational motion of the driven shaft 15 to the wheel cylinder 18. At the same time, the rotational speed of the wheel cylinder 18 can be adjusted by selecting different gear ratios, thereby controlling the frequency of the up-and-down reciprocating motion of the grinding head 8.

[0045] As a further embodiment of the present invention, the grooved roller structure includes a guide groove 22 formed on the lifting rod 19 and a ball bearing 23 embedded and engaged in the inner wall of the wheel cylinder 18. The ball bearing 23 is movably engaged in the guide groove 22 and slides in cooperation with the guide groove 22.

[0046] In this embodiment, the ball bearing 23 and the guide groove 22 form a grooved roller structure that converts rotational motion into linear motion. When the wheel cylinder 18 rotates, the fixed ball bearing 23 moves relative to the inclined guide groove 22 on the lifting rod 19. Since the lifting rod 19 is restricted from rotating by the limiting component, the lateral force generated by the ball bearing 23 sliding along the guide groove 22 forces the lifting rod 19 to only make reciprocating linear motion along its axial direction, thereby driving the grinding head 8 to rise and fall.

[0047] As a further embodiment of the present invention, the second gear mechanism includes a drive gear 16 fixedly mounted on the transmission disk 11 and an intermediate gear 17 fixedly mounted on the driven shaft 15, wherein the drive gear 16 and the intermediate gear 17 mesh with each other.

[0048] In this embodiment, the drive gear 16 and the intermediate gear 17 constitute a second gear mechanism, which is used to transmit the unidirectional rotational motion of the transmission disk 11 to the driven shaft 15. At the same time, different gear ratios can be selected to achieve a certain deceleration or acceleration of the driven shaft 15.

[0049] The working principle of this invention is as follows: The workflow begins with adding feed powder and detection solvent into the sample container 3 through the feeding pipe 6. At this time, the motor 5 is started to drive the main shaft 4 to rotate clockwise. The rotation of the main shaft 4 directly drives the sample container 3 and the grinding disc 27 to rotate at a uniform speed. On the other hand, through a one-way transmission mechanism composed of an active ratchet 12, a pawl 13, a transmission disc 11, a drive gear 16, an intermediate gear 17, and a second gear mechanism, the power is transmitted to the driven shaft 15. The driven shaft 15 drives the wheel cylinder 18 to rotate through the first gear mechanism composed of an active gear 21 and a driven gear 20. The ball bearings 23 on the inner wall of the wheel cylinder 18 cooperate with the guide groove 22 inside the lifting rod 19 fixed on the grinding head 8, converting the rotational motion of the wheel cylinder 18 into the up-and-down reciprocating motion of the lifting rod 19 and the grinding head 8 along the constraint direction of the limiting guide rod 10 and the limiting guide plate 9. At this time, the rotating grinding disc 27 and the up-and-down reciprocating grinding head 8 cooperate to efficiently grind the feed powder and... After the solvent is uniformly mixed and homogenized by grinding, the motor 5 drives the main shaft 4 to reverse. At this time, the pawl 13 in the one-way transmission mechanism slides on the back of the teeth of the active ratchet 12, interrupting the power transmission. The driven shaft 15, the wheel cylinder 18, and the grinding head 8 stop moving. The main shaft 4 directly drives the sample container 3 and the grinding disc 27 to rotate at high speed, generating a strong centrifugal force. This causes the liquid components in the slurry in the sample container 3 to be filtered through the filter hole 7 and then thrown out. Afterward, they flow through the through hole 24 on the support 2 to the bottom wall of the device body 1 for chemical analysis by the biochemical sensor detector 25. The solid residue is retained in the sample container 3. After the test is completed, the waste liquid can be discharged by the drain valve 26. In addition, an inspection door is provided on the device body 1. After opening, the residue in the sample container 3 can be cleaned. In the whole process, the two core pretreatment functions of grinding and mixing and centrifugal separation are automatically and continuously completed by simply switching the forward and reverse rotation direction of the motor 5, realizing the integration and automation of the detection process.

[0050] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
