[0039] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0041] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention depending on the specific circumstances.

[0042] Example 1

[0043] The present invention provides an auxiliary device for grading livestock carcass products. Figure 1 This is a schematic diagram of the main structure of this embodiment, as shown in Figure 1 As shown, it includes a guide body 2 and a distribution body 3 which are arranged in sequence along the transmission direction of the conveying track 1.

[0044] The guide body 2 is used to transport the hanging bracket 4 of the livestock carcass product connected to the conveyor track 1 along the guide channel defined by it. The guide body 2 is located at the bottom of the conveyor track 1 and effectively guides the hanging bracket 4. Under the guidance and limiting action of the guide body 2, the hanging bracket 4 is transported along the guide channel defined by the guide body 2, preventing the livestock carcass product 5 from swinging significantly during transportation.

[0045] In this embodiment, the hanging bracket 4 adopts an "A"-shaped bracket structure. The top of the "A" shape is used for sliding connection with the conveying track 1, and hooks are provided at both ends of the bottom of the "A" shape for hanging the two halves of the livestock carcass products 5 respectively.

[0046] Figure 2 This is a schematic diagram of the structure of the distribution body in this embodiment. Figure 2 As shown, the distribution body 3 includes a support member 31 , and a distribution component 32 and a mounting seat 33 mounted on the support member 31 .

[0047] In this embodiment, the support member 31 includes a base 311 and a support rod 312 disposed on the base 311. The distribution assembly 32 and the mounting base 33 are both connected to the support rod 312. The bottom of the base 311 is a flat structure that contacts the ground and provides support for the support rod 312 thereon, as well as the distribution assembly 32 and the mounting base 33 mounted on the support rod 312.

[0048] Among them, the distribution component 32 is arranged at the bottom of the conveying track 1 along the transmission direction of the conveying track 1, and is used to ensure that the two portions of livestock carcass products 5 after being split in half are located on both sides of the distribution component 32 when they are transmitted to the distribution component 32, and the two portions of livestock carcass products 5 are respectively close to the two sides of the distribution component 32 and transmitted at a uniform speed along the distribution component. A baffle 34 is provided on the mounting seat 33 to stop the transmission of one of the livestock carcass products, and evaluate and grade the livestock carcass products by measuring the body shape score and back fat thickness of the other livestock carcass product 5. The baffle 34 is provided to avoid mutual interference between the two livestock carcass products 5 during the grading process, and to avoid shaking of the livestock carcass products when measuring the body shape score and back fat thickness of the livestock carcass products, so as to reduce the grading measurement error.

[0049] As an optional embodiment, the distribution assembly 32 includes at least a first distribution member 321 and a second distribution member 322 .

[0050] The second distribution member 322 is located below the first distribution member 321. By providing two sets of distribution members, the livestock carcass products 5 are conveyed at a uniform speed along the upper and lower sets of distribution members, which can more effectively limit the position of the livestock carcass products 5. By using the first and second distribution members 321, 322 to automatically separate the livestock carcass products 5 by size, human error can be avoided.

[0051] Specifically, the mounting seat 33 is located at the bottom of the second distribution member 322, one end of the baffle 34 is connected to the mounting seat 33, and the other end of the baffle 34 is located between the first distribution member 321 and the second distribution member 322. The baffle 34 is provided to intercept the livestock carcass product 5 located on one side, so as to avoid mutual interference between the two livestock carcass products 5 during the grading process, and to avoid shaking of the livestock carcass products. The product is evaluated and graded by measuring the body shape score and back fat thickness of the other livestock carcass product 5.

[0052] The specific working principle of body shape grading is to select points on the surface of the livestock carcass and calculate a score based on the changing curvature at each point. In this embodiment, points are selected at both ends of the livestock carcass product 5 and at the point separated by the first distribution member 321 and the second distribution member 322. Of course, more points can be selected based on actual grading needs to facilitate calculating scores based on the changing curvature of each section.

[0053] During actual production and use, the body shape score and backfat thickness of the livestock carcass product 5 can be collected in conjunction with a visual sensor, and a control system connected to the visual sensor can be used to perform calculations according to a preset algorithm to automatically quantify the body shape score and backfat thickness of the livestock carcass product 5, thereby realizing automatic grading of livestock carcass products and reducing grading errors caused by human or other external factors.

[0054] As an optional implementation, Figure 3 is a schematic structural diagram of the first distribution member in this embodiment, as shown in FIG. Figure 3 As shown, the first distribution member 321 and the second distribution member 322 both include a first distribution rod 3211 and a second distribution rod 3212 arranged parallel to each other. The first distribution rod 3211 and the second distribution rod 3212 are respectively connected to the two sides of the support member 31. When in use, the two livestock carcass products 5 after being split in half are respectively transmitted along the guiding effect of the first distribution rod 3211 of the first distribution member 321 and the second distribution member 322, and the guiding effect of the second distribution rod 3212 of the first distribution member 321 and the second distribution member 322.

[0055] Specifically, in this embodiment, the first distribution member 321 and the second distribution member 322 also include a guide end 3213, which has a "V"-shaped structure. One end of the "V"-shaped structure is connected to the first distribution rod 3211, and the other end of the "V"-shaped structure is connected to the second distribution rod 3212.

[0056] By arranging guide ends at the ends of the first distribution member 321 and the second distribution member 322, the two portions of livestock carcass products 5 after being split in half can be smoothly distributed on both sides of the guide end 3213, so that the two portions of livestock carcass products 5 can be transmitted respectively along the two first distribution rods 3211 on the first distribution member 321 and the second distribution member 322 on the same side and the two second distribution rods 3212 on the first distribution member 321 and the second distribution member 322 on the other side.

[0057] It is understandable that, in actual production and use, other structures that can guide the end portion, such as a "U"-shaped structure, etc., may also be adopted.

[0058] As an optional implementation, Figure 4 Schematic diagram of the structure of the blocking rod in this embodiment. Figure 4 As shown, the blocking rod 34 comprises at least a first connecting rod 341, a second connecting rod 342 and a third connecting rod 343 connected in sequence. The second connecting rod 342 is arranged perpendicular to the first connecting rod 341, and an obtuse angle is set between the third connecting rod 343 and the second connecting rod 342.

[0059] A power device is housed within the mounting base 33, and a first connecting rod 341 is connected to the power device. In this embodiment, the power device is a pneumatic cylinder. During operation, while the blocking rod 34 effectively intercepts and stops the split-half animal carcass products 5 on one side, the suspension bracket 4 continues to move along the conveying direction of the conveyor track 1. When the suspension bracket 4 has moved sufficiently to allow data collection on the other side of the animal carcass products 5 to be completed, the first connecting rod 341, driven by the power device, rotates 90°, aligning the second connecting rod 342 with the conveying direction of the conveyor track 1. This releases the blocking of the animal carcass products 5, allowing the animal carcass products 5 to continue to travel along the conveying direction of the conveyor track 1 along with the suspension bracket 4. The first connecting rod 341 then returns to its original position, and the aforementioned steps are repeated for the next group of split-half animal carcass products 5, allowing the grading operation to proceed.

[0060] As an optional embodiment, the guide body 2 includes a first guide rod 21 and a second guide rod 22 arranged in parallel. The first guide rod 21 and the second guide rod 22 divide the guide body 2 into a first guide section 201 , a second guide section 202 and a third guide section 203 .

[0061] Among them, when the suspension bracket 4 is located in the first guide section 201, it is guided only by the first guide rod 21; when the suspension bracket 4 is located in the second guide section 202, it is guided between the first guide rod 21 and the second guide rod 22; when the suspension bracket 4 is located in the third guide section 203, it is guided only by the second guide rod 22.

[0062] By setting the guide body 2 including the first guide rod 21 and the second guide rod 22 arranged in parallel, the suspension bracket 4 and the animal carcass product 5 suspended on the suspension bracket 4 are limited to prevent the animal carcass product 5 suspended on the conveying track 1 from turning randomly.

[0063] In this embodiment, the third guide section 203 is provided with a clearance structure 220. Specifically, an arc-shaped clearance groove is provided at the end of the second guide rod 22. When the livestock carcass product 5 is hung upside down, the animal's hoof is located at the connection with the suspension bracket 4. Moreover, when the suspension bracket 4 runs to the third guide section 203, it is guided only by the second guide rod 22. Since there is no stop on the other side, the suspension bracket 4 will turn. The provision of the clearance groove prevents the animal's hoof from scraping against the second guide rod 22 at the connection with the suspension bracket 4 during the turn, causing the livestock carcass product 5 to fall off the suspension bracket 4.

[0064] As an optional embodiment, a track scale 7 is also provided on the conveying track 1. The track scale 7 can be arranged on the front side of the guide body 2 along the conveying direction of the conveying track 1, or can be arranged on the rear side of the distribution body 3 along the conveying direction of the conveying track 1 to measure the weight of the livestock carcass product 5.

[0065] In this embodiment, using pig carcasses as an example, a distribution system is arranged behind the distribution body 3 along the conveyor track 1. After quantitatively grading the pig carcass' body shape and backfat thickness, the carcass is weighed and measured, analyzing the three evaluation indicators—body shape, backfat thickness, and weight—to ensure more accurate grading results. Finally, the body shape, backfat thickness, and weight of the pig carcasses are quantitatively graded numerically to form the purchasing grade.

[0066] Example 2

[0067] Figure 5 is a schematic diagram of the structure of the distribution body in this embodiment, Figure 6 yes Figure 5 The enlarged structural diagram at A is as follows: Figure 5 and Figure 6 As shown, different from the first embodiment, in this embodiment, a slide rail 313 / slider 314 is provided on the support member 31, and a slider 314 / slide rail 313 for sliding in cooperation with the slide rail 313 / slider 314 is provided on the first distribution member 321 and the second distribution member 322.

[0068] By arranging a slide rail 313 / slider block 314 on the support member 31, and arranging a slider block 314 / slide rail 313 on the first distribution member 321 and the second distribution member 322 for sliding in cooperation with the slide rail 313 / slider block 314, the positions of the first distribution member 321 and the second distribution member 322 on the support member 31 can be adjusted according to actual usage needs before use, so that this distribution body 3 is more suitable for grading different types of carcass products.

[0069] Example 3

[0070] This embodiment provides a livestock carcass product grading system. Figure 7 It is a structural diagram of this embodiment, as shown in FIG. Figure 7 As shown, it includes the auxiliary device for grading livestock carcass products described in either embodiment 1 or embodiment 2.

[0071] This livestock carcass product grading system can be used in conjunction with a visual sensor and a control system to achieve intelligent grading of livestock carcass products.

[0072] During actual production and use, this embodiment arranges the first visual sensor 61 and the second visual sensor 62 on one side of the distribution body 3. Specifically, the first visual sensor 61 and the second visual sensor 62 are arranged in sequence along the transmission direction of the conveying track 1, and the first visual sensor 61 and the second visual sensor 62 are both electrically connected to the control system.

[0073] Figure 8This is a schematic diagram of the installation structure of the visual sensor in this embodiment. Figure 8 As shown, in this embodiment, the visual sensor is installed on a liftable bracket, so that the height of the visual sensor can be adjusted according to actual usage needs.

[0074] The first and second visual sensors 61 and 62 in this embodiment can be selected from commercially available visual sensor products, such as industrial cameras or video cameras, depending on actual usage requirements. The specific model is not specifically limited herein, as long as they can be used in conjunction with the control system to capture clear images and facilitate numerical quantification of the body shape score and backfat thickness of the livestock carcass product 5. Similarly, the controller in the control system can be a PLC or other control device. The specific model is not specifically limited herein, as long as it meets the usage requirements.

[0075] The first and second distribution members 321, 322 separate the two animal carcass products 5 and ensure they are conveyed closely against the sides of the first and second distribution members 321, 322, respectively, to limit the position of the animal carcass products 5. During operation, the animal carcass products 5 are conveyed at a constant speed along the first and second distribution members 321, 322. A stopper 34 provided on the mounting base 33 stops the conveyance of one of the animal carcass products, preventing interference between the two animal carcass products 5 during grading and preventing shaking of the animal carcass product 5 when the first and second visual sensors 61, 62 are used to collect data from the other animal carcass product 5.

[0076] During actual production and use, the first visual sensor 61 and the second visual sensor 62 are respectively used to collect the body shape and backfat thickness of the livestock carcass product 5 during the transmission process of the livestock carcass product 5. The control system calculates and analyzes them according to a preset algorithm, and automatically quantifies the body shape score and backfat thickness of the livestock carcass product 5 in the form of numerical values.

[0077] A track scale 7 is also provided on the conveying track 1 , which can grade the livestock carcass products 5 based on three evaluation indicators: body shape, backfat thickness, and weight.

[0078] Of course, in actual production and use, other grading auxiliary products can also be added according to the actual characteristics of the livestock carcass product 5 to make the application scope of this livestock carcass product grading system wider.

[0079] In addition, in some cases, this livestock carcass product grading system is also applicable to the grading of poultry or other carcass products.

[0080] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
