Description

Technical Field

[0001] This application relates to the field of meat processing technology, specifically to a cattle slaughtering saw for preventing organ rupture and opening the chest. Background Technology

[0002] The cattle slaughtering anti-organ rupture open-chest chainsaw is a special tool designed specifically for use in the slaughtering process of beef cattle to prevent organ rupture.

[0003] An existing patent (publication number: CN209376573U) discloses a safety-type open-chest electric saw for cattle slaughtering, belonging to the technical field of slaughtering. The key technical points of the solution are: a housing and a saw blade with serrations extending from the housing. The saw blade is connected to a drive mechanism that drives the saw blade to reciprocate and extend. A protective shell is provided on the side of the saw blade with serrations to protect the serrations. The protective shell is hinged to the housing so that the protective shell can rotate to cover or rotate away from the serrations of the saw blade. This achieves the effect of reducing the safety hazards caused by the exposed serrations of the saw blade when the electric saw is not in use and improving the safety of the electric saw.

[0004] The above-mentioned device has achieved the effect of reducing the safety hazards caused by the exposed teeth of the saw blade when the chainsaw is idle and improving the safety of the chainsaw. However, during use, it is not easy to control the feed rate and it is easy to damage the internal organs. Secondly, after use, the surface of the saw blade is prone to being mixed with animal tissue and blood, which affects the hygiene of subsequent slaughter. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a cattle slaughtering saw that prevents organ rupture and opens the chest, which has the advantages of convenient operation and automatic cleaning, and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a cattle slaughtering anti-organ rupture chest-opening electric saw, including a housing and a saw blade extending from the housing, a protective shell is fixedly connected to one side of the housing, the saw blade is located inside the protective shell, and two protective plates are slidably connected to both sides of the protective shell, with a limiting mechanism provided on the side of the two protective plates that are far apart from each other.

[0007] Each of the aforementioned limiting mechanisms includes a slide cylinder, a plug rod, a spring, two connecting rods, and two limiting posts;

[0008] Two sets of ratchet blocks are fixedly connected to both sides of the protective shell;

[0009] A cleaning tube is fixedly embedded on the upper surface of the protective shell, and multiple nozzles are fixedly connected to the bottom end of the cleaning tube, with each nozzle located above the saw blade.

[0010] Through the above-described design, including the limiting mechanism, ratchet block, and guard plate used in conjunction with it, this chainsaw can precisely adjust the length of the guard plate extending beyond the protective shell. This not only allows operators to control the saw blade's feed rate according to actual needs, effectively preventing organ rupture caused by excessive cutting depth, but also greatly improves the precision and safety of slaughtering operations. The design of the guard plate and limiting mechanism not only helps control the feed rate but also shields the saw blade, avoiding the risk of injury to workers due to accidental contact with the saw teeth. The roller design on the guard plate improves the smoothness of overall movement on the animal's skin, making the chainsaw more flexible and convenient to use. By fixing and embedding cleaning tubes and nozzles on the upper surface of the protective shell, as well as connecting to an external water supply pipe, this chainsaw can promptly clean the saw blade surface after use, effectively removing adhering animal tissue and blood. This design not only maintains the hygiene and performance of the saw blade but also reduces the possibility of bacterial growth, further ensuring the safety and hygiene of the meat products.

[0011] Furthermore, a set of rollers is rotatably connected to one end of each of the two guard plates.

[0012] The above solution, through the setting of rollers, can improve the smoothness of overall movement.

[0013] Furthermore, each of the slide cylinders is fixedly connected to the adjacent guard plate, each of the insert rods is slidably inserted into the adjacent slide cylinder, both ends of each spring are fixedly connected to the adjacent slide cylinder and insert rod respectively, each of the connecting rods is fixedly connected to the adjacent insert rod, each of the limiting posts is fixedly connected to the adjacent connecting rod, and each of the limiting posts is in contact with the adjacent ratchet block.

[0014] The above solution, through the setting of the limiting mechanism, can adjust the length of the guard plate extending out of the protective shell, thereby facilitating the control of the saw blade's feed rate, and at the same time, can shield the saw blade to prevent workers from accidentally touching it.

[0015] Furthermore, a connecting pipe is fixedly connected to the outer surface of the cleaning tube.

[0016] The above solution, through the installation of connecting pipes, facilitates the connection between users and external water supply pipes.

[0017] Furthermore, a drainage groove is provided at the bottom of the protective shell.

[0018] The above solution, with the installation of drainage channels, facilitates the discharge of cleaning wastewater.

[0019] Furthermore, a pull ring is fixedly connected to one end of each of the aforementioned inserts.

[0020] The above solution, with the pull ring, allows users to easily release the limits of the roller and ratchet, and also makes it easy for users to pull the guard plate to move.

[0021] Furthermore, a limiting rod is fixedly connected to one end of each of the protective plates, and each limiting rod is slidably inserted into the protective shell.

[0022] The above solution, through the setting of the limit rod, can improve the movement stability of the guard plate.

[0023] Furthermore, a compression spring is fitted onto the outer surface of each of the limiting rods.

[0024] The above solution, through the setting of the compression spring, can achieve the purpose of automatic reset of the guard plate.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] This cattle slaughtering saw, designed with a limiting mechanism and corresponding ratchet block and guard plate, allows for precise adjustment of the guard plate's extension length beyond the protective shell. This not only facilitates operator control of the saw blade's feed rate, effectively preventing organ rupture due to excessive cutting depth, but also significantly improves the precision and safety of slaughtering operations. The guard plate and limiting mechanism not only help control the feed rate but also shield the saw blade, avoiding the risk of injury to workers from accidental contact with the saw teeth. The roller design on the guard plate improves the smoothness of movement across the animal's skin, making the saw more flexible and convenient to use. By embedding a cleaning tube and nozzle on the upper surface of the protective shell, along with a water supply pipe connected to the outside, the saw blade can be cleaned promptly after use, effectively removing adhering animal tissue and blood. This design not only maintains the hygiene and performance of the saw blade but also reduces the possibility of bacterial growth, further ensuring the safety and hygiene of the meat.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The cattle slaughtering anti-organ rupture chest-opening electric saw in this embodiment includes a housing 1 and a saw blade 101 extending from the housing 1. A protective shell 2 is fixedly connected to one side of the housing 1. The saw blade 101 is located inside the protective shell 2. Two protective plates 3 are slidably connected to both sides of the protective shell 2. Each of the two protective plates 3 is provided with a limiting mechanism 4 on the side that is far away from each other. A drainage groove 10 is provided at the bottom of the protective shell 2. The drainage groove 10 facilitates the discharge of cleaning wastewater.

[0036] Please see Figure 1 , Figure 4 and Figure 5 Each of the two guard plates 3 has a set of rollers 8 rotatably connected to one end. The rollers 8 improve the smoothness of the overall movement. Each limiting mechanism 4 includes a slide cylinder 401, a rod 402, a spring 403, two connecting rods 404, and two limiting posts 405. Each slide cylinder 401 is fixedly connected to the guard plate 3 adjacent to it. Each rod 402 is slidably inserted into the slide cylinder 401 adjacent to it. The two ends of each spring 403 are fixedly connected to the slide cylinder 401 and the rod 402 adjacent to it, respectively. Each connecting rod 404 is fixedly connected to the rod 402 adjacent to it. Each limiting post 405 is fixedly connected to the connecting rod 404 adjacent to it. Each limiting post 405 contacts the ratchet block 5 adjacent to it. The limiting mechanism 4 allows for adjustment of the length of the guard plate 3 extending out of the protective shell 2, thereby facilitating control of the feed amount of the saw blade 101. It also shields the saw blade 101 to prevent accidental contact by the operator.

[0037] Two sets of ratchet blocks 5 are fixedly connected to both sides of the protective shell 2;

[0038] Please see Figure 1 , Figure 2 and Figure 3 The upper surface of the protective shell 2 is fixedly embedded with a cleaning tube 6. The bottom end of the cleaning tube 6 is fixedly connected to multiple nozzles 7. Each nozzle 7 is located above the saw blade 101. Through the setting of the cleaning tube 6 and the nozzles 7, the animal tissue and blood adhering to the surface of the saw blade 101 can be cleaned. The outer surface of the cleaning tube 6 is fixedly connected to a connecting tube 9. Through the setting of the connecting tube 9, it is easy for the user to connect to the external water supply pipe.

[0039] Please see Figure 1 , Figure 2 and Figure 3 Each insert rod 402 has a pull ring 11 fixedly connected to one end. The pull ring 11 allows the user to release the limit of the roller 8 and the ratchet block 5, and also allows the user to pull the guard plate 3 to move. Each guard plate 3 has a limit rod 12 fixedly connected to one end. Each limit rod 12 is slidably inserted into the protective shell 2. The limit rod 12 improves the movement stability of the guard plate 3. Each limit rod 12 has a compression spring 13 sleeved on its outer surface. The compression spring 13 enables the guard plate 3 to automatically reset.

[0040] The cattle slaughtering saw for preventing organ rupture and opening the chest in this embodiment, through its designed limiting mechanism 4 and the corresponding ratchet block 5 and guard plate 3, allows for precise adjustment of the length of the guard plate 3 extending beyond the protective shell 2. This not only facilitates the operator in controlling the feed rate of the saw blade 101 according to actual needs, effectively preventing organ rupture caused by excessive cutting depth, but also greatly improves the precision and safety of slaughtering operations. The design of the guard plate 3 and limiting mechanism 4 not only helps control the feed rate but also shields the saw blade 101, preventing workers from being injured by excessive cutting depth. To reduce the risk of injury from accidentally touching the saw teeth, the roller design on the guard plate 3 improves the smoothness of movement over the animal's skin, making the chainsaw more flexible and convenient to use. By fixing and embedding the cleaning tube 6 and nozzle 7 on the upper surface of the protective shell 2, as well as the water supply pipe connected to the outside, this chainsaw can clean the surface of the saw blade 101 in time after use, effectively removing adhering animal tissue and blood. This design not only maintains the hygiene and performance of the saw blade 101, but also reduces the possibility of bacterial growth, further ensuring the safety and hygiene of meat products.

[0041] The working principle of the above embodiment is as follows: The operator first starts the drive mechanism of the electric saw, causing the saw blade 101 to reciprocate. At the same time, the operator checks and ensures that the cleaning pipe 6 is connected to the external water supply pipe to prepare for subsequent cleaning of the saw blade 101. Depending on the size of the beef cattle to be slaughtered and the location of the organs, the operator pulls the pull ring 11 on the insertion rod 402, causing the insertion rod 402 to slide inside the slide cylinder 401, which in turn moves the connecting rod 404 and the limiting post 405. The degree of contact between the limiting post 405 and the ratchet block 5 determines the length of the guard plate 3 extending out of the protective shell 2, thereby precisely adjusting the feed amount of the saw blade 101. This design effectively prevents damage caused by... To prevent organ rupture caused by excessive cutting depth, after confirming that the cutting depth has been adjusted to the appropriate position, the operator aligns the saw blade 101 with the area to be cut and pushes the saw forward. The roller 8 design on the guard plate 3 improves the smoothness of the overall movement on the animal skin, making the saw more flexible and convenient to use. After slaughtering, cleaning water is sprayed onto the saw blade 101 through the cleaning pipe 6. The cleaning water is sprayed from the nozzle 7 and, together with the rotation of the saw blade 101, covers the surface of the saw blade 101, effectively removing adhering animal tissue and blood. At the same time, the design of the drainage trough 10 ensures that the cleaning wastewater can be discharged smoothly, keeping the working environment clean.
