Description

Technical Field

[0001] The utility model belongs to the technical field of aquatic product processing machinery, in particular to a back-opening and visceral-removing loach and eel slaughtering machine. Background Art

[0002] Loach and eel are special economic fish in my country. They are good at digging holes, have tender meat, and are delicious. They are rich in calcium, iron, phosphorus, and a variety of essential amino acids for the human body. They are very popular delicacies. Loach is small and slender, with a sub-cylindrical front end, a round abdomen, and a flat back end. The loach has a smooth surface and rich mucus, which makes it very slippery and difficult to hold. Eels are similar in shape to loach, so they are very difficult to slaughter. For a long time, loach and eel slaughtering has been mainly done manually. The manual slaughtering method is not only labor-intensive and inefficient, but also has poor safety performance.

[0003] Since the structural characteristics of loach and eel are very different, the machines for killing them will also be very different. The existing loach and eel killing equipment cannot achieve the designed effect in actual use. For example, the patents "eel and loach killing machine" CN201520939978.4 and "eel and loach killing machine" CN201310140140.4 are machines for killing eels, but they are not suitable for killing loaches in actual use.

[0004] Obviously, the existing loach and eel slaughtering devices have problems such as incomplete cleaning of the internal organs, missed killing and jamming of the machine, and the loach and eel slaughtering machines with open backs do not have the function of scraping the internal organs. Utility Model Content

[0005] The utility model aims to provide a back-opening and visceral-removing loach and eel slaughtering machine, which can open the back of loach or eel through a back-opening blade and then clean the viscera through a rotating toothed scraper.

[0006] The utility model is realized by the following technical solutions:

[0007] A back-opening and eviscerating loach and eel slaughtering machine comprises a machine base, on which a transmission channel extending in the front-rear direction is formed for slaughtering and processing loach and eel;

[0008] A swallowing mechanism is installed on the machine base; the swallowing mechanism is located at the entrance of the transmission channel and is used to push the loach or eel on the transmission channel to move toward the exit end of the transmission channel;

[0009] Two sets of elastic limit components are installed on the machine base; the two sets of elastic limit components are symmetrical on the transmission channel and close to the swallowing mechanism on the transmission channel; the left elastic limit component and the right elastic limit component can be elastically extended and retracted in the left and right directions, and the two are matched with each other to clamp the loach or eel on the transmission channel; the elastic limit components on the left and right sides of the transmission channel can adaptively elastically extend and retract according to the size of the loach and eel, ensuring that loach and eel of different sizes can be clamped; when the swallowing mechanism pushes the loach and eel to move toward the exit of the transmission channel, the loach and eel are pushed between the two elastic limit components matched with each other on the left and right, and the two elastic limit components clamp the loach and eel;

[0010] A back-opening blade for breaking the back of loach or eel and a driving mechanism for driving the back-opening blade to rotate are installed on the machine base. The bottom of the back-opening blade extends into the transmission channel and is close to the engulfing mechanism. When the back-opening blade rotates, the back of the loach or eel on the transmission channel can be broken from above; when the loach or eel is pushed between the left elastic limiting component and the right elastic limiting component by the engulfing mechanism, the two elastic limiting components clamp the loach or eel from the left and right sides to stabilize the loach or eel. As the engulfing mechanism continues to push the loach or eel, the rotating back-opening blade breaks the back of the loach or eel from above the loach or eel while the loach or eel moves toward the exit direction on the transmission channel.

[0011] The left and right walls of the back-opening blade are both fixed with conical separators for separating the loach or eel whose back is broken to the left and right sides. The conical separators can rotate synchronously with the back-opening blade. When the back-opening blade breaks the back of the loach or eel, the conical separators on the left and right sides extend into the loach or eel from the broken back and separate the loach or eel to both sides.

[0012] An elastic pressing block assembly for flattening the separated loaches and eels is arranged on the machine base, and the elastic pressing block assembly is located above the transmission channel and at the rear side of the elastic limiting assembly; the loaches and eels with their backs opened are separated by the conical separator and pushed to the bottom of the elastic pressing block assembly, and the elastic pressing block assembly can be elastically raised and lowered, and the interval between the elastic pressing block assembly and the transmission channel can be elastically adjusted according to the thickness of the loaches or eels behind their backs. As the loaches and eels are continuously pushed on the transmission channel, the elastic pressing block assembly flattens the loaches and eels passing through the transmission channel below them;

[0013] A first conveying rod for pushing the loaches and eels that have been flattened on the conveying channel to continue to move toward the outlet end of the conveying channel and a driving mechanism for driving the first conveying rod to rotate are installed on the machine base. The top of the first conveying rod extends into the conveying channel and is located below the elastic pressure block assembly. When the first conveying rod rotates, it can push the loaches and eels that have been flattened on the conveying channel to continue to move toward the outlet end of the conveying channel.

[0014] A toothed scraper for scraping off the flattened viscera of loach and eel on the transmission channel and a driving mechanism for driving the toothed scraper to rotate are arranged on the machine base. The bottom of the toothed scraper extends into the transmission channel. After the elastic pressing block assembly and the first transmission rod flatten the open-back loach and eel, and under the pushing action of the first transmission rod, the toothed scraper can scrape off the flattened viscera of loach and eel on the transmission channel when it rotates.

[0015] Furthermore, the engulfing mechanism includes two needle rollers installed at the entrance of the transmission channel and a driving mechanism installed on the machine base for driving the two needle rollers to rotate; the two needle rollers are spaced apart in the left and right directions on the transmission channel, and a gap is formed between the two needle rollers for loaches and eels to pass through. When the two needle rollers rotate, the loaches and eels can be pushed into the gap and move toward the exit end of the transmission channel; when the loaches and eels are slaughtered, the two needle rollers rotate and squeeze the loaches or eels at the entrance of the transmission channel, so that the loaches or eels are squeezed into the gap between the two needle rollers at the entrance of the transmission channel, and with the continuous pushing action of the two needle rollers, the loaches or eels move toward the exit end on the transmission channel.

[0016] Furthermore, the needle roller is composed of a cylinder and a plurality of needle-shaped sharp protrusions fixed to the outer wall of the cylinder. The needle-shaped sharp protrusions can grip the loach or eel, thereby pushing the loach or eel forward as the cylinder rotates.

[0017] Furthermore, each group of the elastic limiting components is composed of a slider, a guide rod and a spring, and a give way groove is opened on the end surface of the slider close to the needle roller, so that it can cooperate with the convex and concave of the needle roller to form a connection, ensuring that the loach or eel on the transmission channel can smoothly enter between the left and right elastic limiting components; the left and right sliders can both move in the left and right directions, and when the engulfing mechanism pushes the loach and eel to move toward the exit of the transmission channel, the loach and eel are pushed between the two sliders that cooperate with each other on the left and right. The two sliders clamp the loach and eel, and can adaptively move in the left and right directions according to the body size of the loach and eel, ensuring that loach and eel of different sizes can be clamped.

[0018] Furthermore, the back-opening blade is a polygonal blade, wherein the polygonal blade includes but is not limited to a circular blade. When the back-opening blade rotates at a high speed, it can cut loaches and eels at multiple points, which not only ensures that the backs of loaches and eels are quickly cut, but also greatly extends the service life of the back-opening blade.

[0019] Furthermore, the first conveying rod is composed of a cylinder and a plurality of sharp protrusions arranged on the outer wall of the cylinder. When the first conveying rod rotates, under the limiting action of the elastic pressure block assembly above the conveying channel, the plurality of sharp protrusions of the first conveying rod penetrate into the flesh of the loach or eel to push the loach or eel to move to the outlet end on the conveying channel.

[0020] Furthermore, a second conveying rod and a driving mechanism for driving the second conveying rod to rotate are installed on the machine base, the top of the second conveying rod extends into the conveying channel and is located below the toothed scraper. When the second conveying rod rotates, it can push the loaches and eels that have been flattened on the conveying channel to continue to move toward the outlet end of the conveying channel; after the elastic pressure block assembly and the first conveying rod flatten the open-back loaches and eels, and under the pushing action of the first conveying rod and the second conveying rod, the toothed scraper can scrape off the viscera of the loaches and eels that have been flattened on the conveying channel when the toothed scraper rotates. The second conveying rod can improve the conveying effect of the open-back loaches and eels, and can improve the scraping effect of the toothed scraper on the viscera of the loaches and eels.

[0021] Furthermore, two groups of elastic support components for controlling the elastic lifting and lowering of the second conveying rod are installed on the machine base. The two groups of elastic support components are respectively located at both ends of the second conveying rod. The spacing between the second conveying rod and the toothed scraper can be elastically adjusted according to the thickness of the loach or eel behind the back, so that the second conveying rod and the toothed scraper are suitable for conveying and scraping off the internal organs of loach or eel slices of different thicknesses.

[0022] Furthermore, the toothed scraper is composed of a cylinder and a plurality of teeth evenly distributed on the outer wall of the cylinder. The toothed scraper can efficiently clean the flattened viscera of loach or eel by rotating.

[0023] Furthermore, an elastic pressing block assembly base is installed on the machine base, and the elastic pressing block assembly and the toothed scraper are both installed on the elastic pressing block assembly base. The space between the elastic pressing block assembly and the transmission channel can be elastically adjusted according to the thickness of the back of the loach or eel after it is opened, so that the open-back loach or eel can pass through and flatten it. After the elastic pressing block assembly base is removed from the machine base, the elastic pressing block assembly and the toothed scraper can be separated from the machine base.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] When the slaughtering machine slaughters loaches or eels, the loaches or eels are pushed by the swallowing mechanism at the entrance of the transmission channel to move on the transmission channel, and the loaches or eels are prevented from going off the track by the limitation of the left and right elastic limiting components in the left and right directions, and the rotating back-opening blade can break the back of the loach or eel from above, and the conical separator can separate the back-opened loach or eel at the same time, and the back-opened and separated loach or eel is sent to the bottom of the elastic pressing block component to be flattened, and can be pushed twice by the first transmission rod on the transmission channel and then scraped from the top by the toothed scraper to remove the internal organs; the slaughtering processing method can also clean the internal organs, and the slaughtering machine is suitable for slaughtering loaches and eels, and has the advantages of compact structure, small size, light weight, small footprint, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Specifically, the driving mechanism for driving the two needle rollers 1-1 to rotate is composed of a reduction motor, a transmission shaft and a transmission gear. The needle rollers 1-1 and the driving mechanism of the engulfing mechanism 1 are both prior arts, which have been recorded in detail in the invention patent with the authorization announcement number CN107361116B and the invention name of a loach or eel slaughtering device previously applied for by the applicant, and will not be repeated here.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, two groups of elastic limit components 3 are installed on the machine base 2; the two groups of elastic limit components 3 are symmetrical on the transmission channel 9, and are close to the swallowing mechanism 1 on the transmission channel 9; the left elastic limit component 3 and the right elastic limit component 3 can both be elastically extended and retracted in the left and right directions, and the two are matched with each other to clamp the loach or eel on the transmission channel 9; the elastic limit components 3 on the left and right sides of the transmission channel 9 can adaptively elastically extend and retract according to the body size of the loach and eel to ensure that loach and eel of different sizes can be clamped; when the swallowing mechanism 1 pushes the loach and eel to move toward the exit direction of the transmission channel 9, the loach and eel are pushed between the two elastic limit components 3 matched with each other on the left and right, and the two elastic limit components 3 clamp the loach and eel.

[0038] like Figures 1 to 4As shown, a back-opening blade 4 for breaking the back of loach and eel and a driving mechanism for driving the back-opening blade 4 to rotate are installed on the machine base 2. The bottom of the back-opening blade 4 extends into the transmission channel 9 and is close to the swallowing mechanism 1. When the back-opening blade 4 rotates, the back of the loach and eel on the transmission channel 9 can be broken from above; the back-opening blade 4 is a polygonal blade, and the back-opening blade 4 can cut the loach and eel at multiple points when it rotates at a high speed, which not only ensures that the back of the loach and eel is quickly cut, but also greatly prolongs the service life of the back-opening blade 4; the polygonal blade includes but is not limited to a circular blade;

[0039] like Figure 1 and Figure 2 As shown, the left and right walls of the back-opening blade 4 are both fixed with a conical separator 5 for separating the loach and eel whose backs are broken open to the left and right sides, and the conical separator 5 can rotate synchronously with the back-opening blade 4;

[0040] Specifically, the driving mechanism for driving the back-opening blade 4 to rotate is composed of a reduction motor and a transmission shaft, etc., which is a prior art, and has been described in detail in the invention patent with the authorization announcement number CN107361116B and the invention name of a loach or eel slaughtering device previously applied by the applicant, and will not be repeated here;

[0041] When the loach or eel is pushed between the left elastic limit component 3 and the right elastic limit component 3 by the engulfing mechanism 1, the two elastic limit components 3 clamp the loach or eel from the left and right sides to stabilize the loach or eel. As the engulfing mechanism 1 continues to push the loach or eel, the loach or eel moves toward the exit on the conveying channel 9, and the rotating back-opening blade 4 breaks the back of the loach or eel from above. While the back-opening blade 4 breaks the back of the loach or eel, the conical separators 5 on the left and right sides extend into the loach or eel from the broken back and separate the loach or eel to both sides.

[0042] like Figure 4 As shown, an elastic pressing block assembly base 10 is installed on the machine base 2, and an elastic pressing block assembly 6 for flattening the separated loaches and eels is installed on the elastic pressing block assembly base 10. Figure 1 , Figure 3 and Figure 4 As shown, the elastic pressing block assembly 6 is located above the transmission channel 9 and at the rear side of the elastic limiting assembly 3; the loach and eel with their backs opened are separated by the conical separator 5 and pushed to the bottom of the elastic pressing block assembly 6. The elastic pressing block assembly 6 can be elastically raised and lowered, and the spacing space between the elastic pressing block assembly 6 and the transmission channel 9 can be elastically adjusted according to the thickness of the loach or eel behind the open back. As the loach and eel are continuously pushed on the transmission channel 9, the elastic pressing block assembly 6 flattens the loach and eel passing through the transmission channel 9 below it.

[0043] like Figure 1 , Figures 3 to 5 As shown, the machine base 2 is provided with a first conveying rod 7 for pushing the loaches and eels that have been flattened on the conveying channel 9 to continue to move toward the outlet end of the conveying channel 9 and a driving mechanism for driving the first conveying rod 7 to rotate. The top of the first conveying rod 7 extends into the conveying channel 9 and is located below the elastic pressure block assembly 6. When the first conveying rod 7 rotates, it can push the loaches and eels that have been flattened on the conveying channel 9 to continue to move toward the outlet end of the conveying channel 9; specifically, the driving mechanism for driving the first conveying rod 7 to rotate includes a reduction motor, which is a prior art and will not be described in detail here.

[0044] like Figure 1 , Figure 3 and Figure 4 As shown, a toothed scraper 8 for scraping off the flattened loach and eel viscera on the conveying channel 9 and a driving mechanism for driving the toothed scraper 8 to rotate are installed on the elastic pressing block assembly base 10, and the bottom of the toothed scraper 8 extends into the conveying channel 9. After the elastic pressing block assembly 6 and the first conveying rod 7 flatten the open-back loach and eel, and under the driving action of the first conveying rod 7, the toothed scraper 8 can scrape off the flattened loach and eel viscera on the conveying channel 9 when rotating; after the elastic pressing block assembly base 10 is disassembled from the machine base 2, the elastic pressing block assembly 6 and the toothed scraper 8 can be separated from the machine base 2;

[0045] Specifically, the driving mechanism for driving the toothed scraper 8 to rotate is composed of a reduction motor and a transmission shaft, etc. The toothed scraper 8 and the driving mechanism for driving the toothed scraper 8 to rotate are both prior arts, which have been recorded in detail in the invention patent with the authorization announcement number CN107361116B and the invention name of a loach or eel slaughtering device previously applied for by the applicant, and will not be repeated here.

[0046] like Figure 1 , Figures 3 to 5As shown, the base 2 is provided with a second conveying rod 11 and a driving mechanism for driving the second conveying rod 11 to rotate. The top of the second conveying rod 11 extends into the conveying channel 9 and is located below the toothed scraper 8. When the second conveying rod 11 rotates, it can push the loach and eel that have been flattened on the conveying channel 9 to continue to move toward the outlet end of the conveying channel 9; after the elastic pressing block assembly 6 and the first conveying rod 7 flatten the open-back loach and eel, and under the pushing action of the first conveying rod 7 and the second conveying rod 11, the loach and eel are flattened. When the toothed scraper 8 rotates, it can scrape off the flattened viscera of loaches and eels on the conveying channel 9. The second conveying rod 11 can improve the conveying effect of loaches and eels that are about to be opened, and can improve the scraping effect of the toothed scraper 8 on the viscera of loaches and eels; specifically, the driving mechanism of the second conveying rod 11 is the same as the driving mechanism of the first conveying rod 11, ensuring that the second conveying rod 11 rotates in the same direction as the first conveying rod 11, and works together to drive the loaches and eels to move toward the outlet end of the conveying channel 9;

[0047] like Figure 4 and Figure 5 As shown, two groups of elastic support components 12 for controlling the elastic lifting and lowering of the second conveying rod 11 are installed on the machine base 2. The two groups of elastic support components 12 are respectively located at the two ends of the second conveying rod 11, and can elastically adjust the spacing space between the second conveying rod 11 and the toothed scraper 8 according to the thickness of the loach or eel after opening, so that the second conveying rod 11 and the toothed scraper 8 are suitable for conveying and scraping off the internal organs of loach or eel slices of different thicknesses; specifically, the elastic support component 12 is composed of a spring and a guide rod, and the spring can act on the bearing of the second conveying rod 11 to control the elastic lifting and lowering of the second conveying rod 11 in the vertical direction.

[0048] As a preferred embodiment, in this embodiment, each group of the elastic limiting components 3 is composed of a slider, a guide rod and a spring, and a make way groove is opened on the end face of the slider close to the needle roller 1-1, so that it can cooperate with the needle roller 1-1 to form a connection, ensuring that the loach or eel on the transmission channel 9 can smoothly enter between the left and right elastic limiting components 3; the left and right sliders can both move in the left and right directions, and when the engulfing mechanism 1 pushes the loach and eel to move toward the exit direction of the transmission channel 9, the loach and eel are pushed between the two sliders that cooperate with each other on the left and right, and the two sliders clamp the loach and eel, and can adaptively move in the left and right directions according to the body size of the loach and eel, ensuring that loach and eel of different sizes can be clamped.

[0049] As a preferred implementation, in this embodiment, Figure 4As shown, the first conveying rod 7 is composed of a cylinder and a plurality of sharp protrusions arranged on the outer wall of the cylinder. When the first conveying rod 7 rotates, under the limiting action of the elastic pressure block assembly 6 above the conveying channel 9, the plurality of sharp protrusions of the first conveying rod 7 penetrate into the flesh of the loach or eel to push the loach or eel to move to the outlet end on the conveying channel 9; the second conveying rod 11 has the same structure as the first conveying rod 7.

[0050] As a preferred implementation, in this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the toothed scraper 8 is composed of a cylinder and a plurality of teeth evenly distributed on the outer wall of the cylinder. The toothed scraper 8 can efficiently clean the flattened viscera of loach or eel by rotating.

[0051] The working principle and technical effects of this embodiment are as follows:

[0052] When slaughtering loaches or eels, the loaches or eels are sent to the entrance of the transmission channel 9. Under the drive of the driving mechanism of the engulfing mechanism 1, the two needle rollers 1-1 rotate and squeeze the loaches or eels, so that the loaches or eels are squeezed into the gap between the two needle rollers 1-1 at the entrance of the transmission channel 9. With the continuous pushing action of the two needle rollers 1-1, the loaches or eels enter the transmission channel 9 from the entrance and move to the outlet end;

[0053] When the two needle rollers 1-1 of the engulfing mechanism 1 push the loach or eel to move toward the exit end on the transmission channel 9, the loach or eel is pushed between the two elastic limit assemblies 3 that cooperate with each other on the left and right sides. The two elastic limit assemblies 3 clamp the loach or eel, and the clamping and limiting of the left elastic limit assemblies 3 and the right elastic limit assemblies 3 can prevent the loach or eel from being deviated by the two needle rollers 1-1 of the engulfing mechanism 1. At the same time, under the drive of the driving mechanism of the back-opening blade 4, the back-opening blade 4 rotates and breaks open from the upper back of the loach or eel, and the conical separator 5 fixed to the back-opening blade 4 rotates together with the back-opening blade 4 and separates the loach or eel with the broken back to both sides;

[0054] When the back of the loach or eel on the transmission channel 9 is broken, the two sets of elastic limit assemblies 3 can clamp the loach or eel from the left and right sides. After the conical separator 5 separates the front section of the loach or eel whose back has been broken, the loach or eel is pushed into the gap between the elastic pressing block assembly 6 and the transmission channel 9 as the two needle rollers 1-1 continue to push. The elastic pressing block assembly 6 elastically adjusts the spacing between it and the transmission channel 9 according to the thickness of the back of the loach or eel. As the loach or eel is continuously pushed on the transmission channel 9, the elastic pressing block assembly 6 flattens the loach or eel passing through the transmission channel 9 below it.

[0055] As the front section of the loach or eel that has been flattened by the elastic pressing block assembly 6 reaches above the first conveying rod 7 on the conveying channel 9, the first conveying rod 7 is driven by the driving mechanism of the first conveying rod 7 to rotate and push the loach or eel that has been flattened on the conveying channel 9 to continue to move toward the outlet end of the conveying channel 9;

[0056] With the further push of the first conveying rod 7, the front section of the loach or eel that has been flattened by the elastic pressing block assembly 6 reaches below the toothed scraper 8 on the conveying channel 9, and enters between the second conveying rod 7 and the toothed scraper 8. Driven by the driving mechanism of the toothed scraper 8, the elastic pressing block assembly 6 and the first conveying rod 7 press and position the open-back loach or eel, and the push of the first conveying rod 7 and the second conveying rod 11, the toothed scraper 8 rotates and scrapes off the viscera of the loach or eel that has been flattened on the conveying channel 9, effectively achieving the effect of removing the viscera of the loach or eel.

[0057] The slaughtering machine can slaughter loaches and eels. The internal organs of the loaches or eels slaughtered by the slaughtering machine can be cleaned. The slaughtering machine has the advantages of compact structure, small size, light weight, small footprint, etc.
