Detailed Implementation

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0021] like Figures 1 to 4 As shown, this embodiment provides a crayfish processing device 100, including a workbench 11 and a feeding device 10. A conveying track 111 is formed on the workbench 11. The feeding device 10 includes a clamp 12 and a gantry frame. The clamp 12 is slidably mounted on the workbench 11 and can slide along the conveying track 111 and pass through the feeding position. The clamp 12 is used to clamp crayfish and release them when the crayfish reaches the feeding position. The gantry frame includes two vertical rods 131 arranged vertically and a horizontal rod 132 arranged horizontally and connected between the tops of the two vertical rods 131. The feeding position is located between the two vertical rods 131 and below the horizontal rod 132. A baffle 133 is fixed to the lower side of the horizontal rod 132 corresponding to the feeding position. The baffle 133 is used to push the crayfish located at the feeding position away from the clamp 12.

[0022] In practical use, the clamp 12 holds the crayfish and moves it along the conveyor track 111. When the clamp 12 reaches the unloading position, it releases the crayfish. At this time, the baffle 133 on the gantry will push the crayfish away from the clamp 12. Optionally, the baffle 133 is detachably mounted on the crossbar 132, and the position of the baffle 133 on the crossbar 132 is adjustable to adapt to different specifications of the clamp 12.

[0023] The crayfish processing equipment 100 provided in this application can automatically unload processed crayfish from the production line. By setting up a gantry and baffle 133, the crayfish on the clamp 12 can be automatically pushed away from the clamp 12 by the baffle 133 when passing through the gantry, which makes it convenient to collect the processed crayfish and to reload them.

[0024] like Figure 3As shown, in this embodiment, the clamp 12 includes a housing, two first sliders 122, a first motor 123, and a first lead screw shaft 1231. The housing is slidably mounted on the worktable 11. The housing includes a top plate 1211, a first side plate 1212, and a second side plate 1213. The first side plate 1212 and the second side plate 1213 both face a first direction and are spaced apart along the first direction. The top plate 1211 has a first through hole 1214 and a second through hole 1215 extending vertically. The first through hole 1214 and the second through hole 1215 both extend along the first direction and are spaced apart from each other along the first direction. The first side plate 1212 has a third through hole extending along the first direction. The first direction is the tangential direction along the conveying track 111 at the unloading position. The two first sliders 122 are slidably passed through the first through hole 1214 and the second through hole 1215 along the first direction, respectively. Each first slider 122 includes a clamping part 1221 located above the top plate 1211 and a driving part 1222 located below the top plate 1211. The driving part 1222 of each first slider 122 is provided with a threaded hole through it along the first direction. The first motor 123 is mounted on the first side plate 1212 and located outside the housing. The output shaft of the first motor 123 extends into the housing through the third through hole. The first lead screw shaft 1231 is located inside the housing. One end of the first lead screw shaft 1231 is connected to the output shaft of the first motor 123, and the other end of the first lead screw shaft 1231 is rotatably connected to the second side plate 1213. The first lead screw shaft 1231 passes through the threaded holes of the two first sliders 122 in sequence. The first lead screw shaft 1231 has a first lead screw section with a left-hand thread and a second lead screw section with a right-hand thread. The first lead screw section and the second lead screw section are respectively threaded into the threaded holes of the two first sliders 122. The first motor 123 is used to drive the first lead screw shaft 1231 to rotate so as to drive the two first sliders 122 to move closer or further apart.

[0025] In this embodiment, by separating the clamping portion 1221 and the driving portion 1222 of the two first sliders 122 by setting the top plate 1211, interference of the driving structure of the first sliders 122 on the crayfish can be avoided. By providing a first lead screw section with a left-hand thread and a second lead screw section with a right-hand thread on the first lead screw shaft 1231, the rotation of the first lead screw shaft 1231 can drive the two first sliders 122 to move closer or further apart, so only one first motor 123 is needed to drive the two first sliders 122 simultaneously.

[0026] Furthermore, in order to guide the processed crayfish to the height of the workbench 11, a collection component is also installed on the workbench 11. The collection component includes a mounting shaft 21, a bushing 22, and a torsion spring 24. The mounting shaft 21 is fixed to the workbench 11 and extends vertically. The bushing 22 is rotatably fitted onto the mounting shaft 21. An active plate 221 and a driven plate 222 are fixed on the bushing 22 at an angle to each other. The gantry is located between the active plate 221 and the driven plate 222. A guide block 23 is fixed on the side of the driven plate 222 away from the active plate 221. A first chute is formed on the upper side of the guide block 23. The active plate 221 is pushed by the clamp 12 when the clamp 12 passes through the unloading position, so that the guide block 23 moves closer to and contacts the clamp 12, thereby allowing the crayfish pushed away from the clamp 12 by the baffle 133 to enter the first chute. The torsion spring 24 is sleeved outside the bushing 22. The torsion spring 24 has two torsion arms, one of which is connected to the worktable 11 and the other torsion arm is connected to the drive plate 221.

[0027] In practical use, the clamp 12 pushes the drive plate 221, which in turn moves the driven plate 222 and the guide block 23. This causes the guide block 23 to contact the clamp 12, allowing the crayfish falling from the clamp 12 to enter the first chute and slide down to the height of the worktable 11. After the clamp 12 leaves the unloading position, the torsion spring 24 drives the drive plate 221 and the driven plate 222 to reset, waiting for the clamp 12 to pass through the unloading position again.

[0028] By configuring the torsion spring 24, the driving plate 221, and the driven plate 222, the guide block 23 is connected to the fixture 12 only during material unloading. Compared with the technical solution of directly fixing the guide block 23 to the fixture 12, the power consumption for driving the fixture 12 can be reduced.

[0029] Optionally, to guide the crayfish pushed away from the clamp 12 by the baffle 133 into the first chute, such as... Figure 3 As shown, the clamp 12 also includes a slide 124, which is connected to the side of the top plate 1211 opposite to the conveying direction of the conveying track 111. A second chute is formed on the upper surface of the slide 124. The pusher is used to push the crayfish away from the clamp 12 and into the second chute when the guide block 23 approaches and contacts the clamp 12, so that the crayfish slides down along the second chute and the first chute in sequence.

[0030] Understandably, in some embodiments, the slide component 124 may not be provided, and only the guide block 23 may be provided, so that the crayfish can directly enter the first chute.

[0031] In some embodiments, guide block 23 can guide the crayfish away from workbench 11. For example... Figure 1 As shown, the guide block 23 has a shrimp-welcoming position that contacts the clamp 12 and a shrimp-feeding position that extends partially beyond the workbench 11; the active plate 221 is used to drive the guide block 23 to rotate to the shrimp-welcoming position and deform the torsion spring 24; the torsion spring 24 is used to drive the guide block 23 to rotate to the shrimp-feeding position during the process of returning from the deformed state to the natural state; the collection component also includes a collection bucket, which is located directly below the shrimp-feeding position to catch the crayfish that slide off the guide block 23.

[0032] The conveying track 111 can be straight or circular. Figure 1 In the illustrated embodiment, the conveying track 111 is circular. Along the conveying direction of the conveying track 111, there are sequentially arranged a head-removal position, a back-opening position, a line-removing position, and a feeding position. The crayfish processing equipment 100 also includes a head-removal device 30, a back-opening device 40, and a line-removing device 50. The head-removal device 30 is located at the head-removal position on the worktable 11 and is used to cut off the head of the crayfish. The back-opening device 40 is located at the back-opening position on the worktable 11 and is used to cut open the back of the crayfish. The line-removing device 50 is located at the line-removing position on the worktable 11 and is used to remove the crayfish's intestinal tract.

[0033] In a practical implementation, a feeding device can be installed between the head-removal position and the feeding position. In this embodiment, the crayfish to be processed are fed manually between the head-removal position and the feeding position.

[0034] In this embodiment, by sequentially setting the head removal device 30, the back-opening device 40, and the line removal device 50, the entire process of processing crayfish can be achieved.

[0035] like Figure 1 As shown, the head-removing device 30 is fixed to the inner side of the annular conveyor track 111. The head-removing device 30 includes a second cutting device 31, which is used to cut off the head of the crayfish. In a specific implementation, the crayfish's head can be facing the inner side of the annular conveyor track 111 to fix the crayfish at the clamp 12. In this way, when the clamp 12 holds the crayfish and moves to the head-removing device 30, the second cutting device 31 can cut the crayfish's head along the direction of the crayfish's movement.

[0036] After the crayfish's head is cut off, the crayfish will move to point 40 of the back-opening device. For example... Figure 4As shown, in this embodiment, the back-opening device 40 includes a first mounting frame 41, a second slider, and a first cutting machine 43. The first mounting frame 41 is fixed to the worktable 11. A horizontally extending mounting plate 411 is mounted on the top of the first mounting frame 41. A second motor 42 is mounted on the upper side of the mounting plate 411. A gear 421 is fixed on the output shaft of the second motor 42. A groove is recessed on the lower side of the mounting plate 411. The second slider is slidably disposed within the groove along its length. The first cutting machine 43 is fixed below the second slider and located below the mounting plate 411. A rack 431 that meshes with the gear 421 is fixed on the top of the first cutting machine 43. The second motor 42 drives the gear 421 to rotate, thereby causing the second slider and the first cutting machine 43 to slide along the length of the groove.

[0037] In this embodiment, by setting gear 421 and rack 431, the first cutting machine 43 can move during the process of cutting the back of the crayfish, thereby ensuring that the back of the crayfish is fully cut open.

[0038] like Figure 1 and Figure 4 As shown, the two ends of the groove are at different heights. This allows the groove to tilt and the first cutter 43 to slide tilted, thus facilitating the control of the cutting depth on the crayfish's back.

[0039] After the crayfish undergoes the back-opening process, the intestinal tract will be exposed, and the crayfish will proceed to the deveining device at point 50. For example... Figure 1 As shown, the wire removal device 50 includes two columns 51, a second mounting bracket, a second lead screw shaft, a third slider, and a third motor 55. The two columns 51 extend vertically and are fixed to the worktable 11. The second mounting bracket includes a horizontal plate 521 connected to the top of the two columns 51 and two vertical plates 522 connected to both ends of the horizontal plate 521. The second lead screw shaft is located between the two vertical plates 522 and is rotatably connected to each of the two vertical plates 522. The third slider has a threaded hole extending through the length of the second lead screw shaft. The second lead screw shaft passes through the threaded hole of the third slider and is threadedly engaged with the threaded hole of the third slider. The third slider slidably abuts against the horizontal plate 521, and a lifting rod 56 is fixed on the third slider. The third motor 55 is mounted on one of the two vertical plates 522 and connected to the second lead screw shaft. The third motor 55 drives the second lead screw shaft to rotate, thereby causing the third slider to slide along the length of the second lead screw shaft.

[0040] In this implementation, the lifting rod 56 extends into the back of the crayfish to remove the intestinal tract. In this embodiment, by setting a third slider and a second lead screw shaft, the lifting rod 56 can be moved horizontally after penetrating the back of the crayfish, thus ensuring that the intestinal tract is removed.

[0041] To improve the stability of the third slider's sliding motion, the horizontal plate 521 has a guide protrusion protruding towards the second lead screw shaft, and the third slider has a guide groove recessed on one side of the horizontal plate 521. The guide protrusion is used to slide within the guide groove when the third slider slides along the length direction of the second lead screw shaft.

[0042] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
