Description

Technical Field

[0001] The utility model relates to the technical field of cattle slaughtering and skinning, and more specifically, to a cattle skinning machine. Background Art

[0002] When skinning a cow, as the skinning shaft rotates, the cow's body tends to tilt toward the skinning shaft, so that the skinning angle changes, the cow's skin is not easy to be peeled off, and even after skinning, the cow's body will shake greatly, which will cause unsafe factors and greatly affect the skinning efficiency. To solve this problem, the existing skinning machine uses a method of fixing the cow's front legs. A column needs to be set in front of the skinning machine, and the cow's front legs are manually tied to the column to keep the cow's body stable and balanced. This is time-consuming and labor-intensive, and the operation is cumbersome. In addition, the cow carcass is touched many times, which increases the risk of food hygiene and safety.

[0003] Current cattle skinning machines are generally set up with a vertical frame for skinning. The vertically set frame will easily contact the cattle carcass when the skinning device pulls the hide, causing contamination. In addition, most cattle skinning machines on the market use hydraulics to drive the lifting and rotation of the skinning device, which has problems such as loud noise, slow response, and the hydraulic system may leak oil, causing contamination of the cattle carcass.

[0007] Preferably, the back-pushing cylinder includes an upper cylinder, an upper cylinder housing, a lower cylinder and a lower cylinder housing. The upper cylinder is disposed within the upper cylinder housing, and the upper cylinder housing is fixed to the frame. The piston rod I of the upper cylinder is arranged downward, and a rotating plate is hinged to its lower end. One side of the rotating plate is provided with a rotating shaft, and the rotating shaft is horizontally fixed to the upper cylinder housing. The lower cylinder is disposed within the lower cylinder housing, the lower end of the rotating plate is fixedly connected to the upper end of the lower cylinder housing, and the back-pushing frame is disposed below the lower cylinder and fixedly connected to the piston rod II extending out of the lower end of the lower cylinder housing. When the piston rod I of the upper cylinder is driven to extend, the lower cylinder, the lower cylinder housing and the back-pushing frame are rotated to a horizontal state.

[0008] Further, guide rods are further provided on the back-pushing frame. The guide rods are disposed on both sides of the lower cylinder and penetrate through the lower cylinder housing.

[0009] Further, a lifting device is further provided on the frame, which includes a lifting reduction gear, a main shaft, a driven shaft, bearing seats at both ends of the main shaft, a sprocket and an endless chain. The main shaft is horizontally arranged and located at the upper part of the frame. The lifting reduction gear is drivingly connected to the main shaft. The driven shaft is located at the lower part of the frame. The sprocket on the main shaft is connected to the sprocket on the driven shaft through the endless chain. The left and right ends of the lifting bracket on the peeling device are respectively fixed to the corresponding endless chains for moving up and down following the endless chains.

[0010] Preferably, the peeling driving mechanism includes a lifting bracket, a peeling reduction gear, a driving chain, a main sprocket and a driven sprocket. The peeling reduction gear is disposed on the lifting bracket, its driving shaft is connected to the main sprocket, the peeling shaft is connected to the driven sprocket, the driving chain is connected between the main sprocket and the driven sprocket, and the left and right ends of the lifting bracket are respectively disposed on the two endless chains and move up and down following the endless chains.

[0011] Preferably, the frame includes two parallel longitudinal beams, and the two longitudinal beams are connected by cross beams. The longitudinal beams form an inclination angle with the ground. The two endless chains are respectively arranged along the lengths of the two longitudinal beams, and the back-pushing device is disposed at the middle position between the two longitudinal beams.

[0012] Preferably, the peeling shaft of the peeling device is located outside the frame, and the back-pushing frame is located below the peeling shaft.

[0013] The technical solution of the present utility model has the following advantages:

[0014] A. The cattle skinning machine provided by the present utility model is equipped with a back-pushing device on the frame. When skinning a cattle, first, the skinning shaft is driven to rotate. The skinning shaft drives two tightening chains to rotate, so that the two tightening chains simultaneously apply a force to the cowhide, thus quickly peeling off the upper part of the cowhide. Then, the back-pushing device presses against the cow's back, and the skinning device continues to descend while the skinning shaft rotates forward until the entire cowhide is peeled off. Finally, the skinning shaft rotates in the reverse direction to loosen the cowhide and make it fall. During the entire skinning process, there will be no problem of the cattle body shaking, achieving stable structure and convenient use. The present utility model controls the inclination angle of the cattle body during cattle skinning, making the force on the skinning machine structure more reasonable, reducing the labor intensity, and improving the work efficiency.

[0015] B. The two longitudinal beams of the frame of the present utility model are placed parallel and have a certain inclination angle with the ground, reducing the load on the endless chain, avoiding the phenomenon of the endless chain shifting and increasing the friction with the frame, and ultimately reducing the load on the lifting speed reducer. During the skinning process, due to the certain inclination angle between the frame and the ground, the skinning device can skin from far to near during the descending process, reducing contact with the cattle carcass, and making the hide more complete with less meat on the hide.

[0016] C. Each main sprocket in the lifting device of the present utility model is provided with two bearings at both ends to form a statically indeterminate structure with the lifting speed reducer, which can reduce the load on the lifting speed reducer, optimize the force structure, and protect the lifting speed reducer.

[0017] D. The back-pushing device in the present utility model realizes the linear reciprocating motion of the back-pushing frame through the cooperation of the upper and lower cylinders. When the skinning device descends to a predetermined position, the upper cylinder extends to a certain position so that the lower cylinder is parallel to the ground. At this time, the lower cylinder extends, and the back-pushing frame presses against the cow's back to keep the cattle body stable. Such a design reduces the traditional link of manually tying the front legs of the cattle to the column in front of the skinning machine with a chain to maintain stability, reduces the labor intensity of workers, improves work efficiency, reduces contact with the cattle carcass, avoids cattle carcass pollution, and ensures food hygiene and safety. At the same time, the present utility model adds an encoder to the lifting speed reducer to more accurately control the lifting height and rotation angle during cattle skinning, facilitating manual operation.

[0047] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] like Figures 1 to 7 As shown, the utility model provides a cattle skinning machine, including a frame 1 and a skinning device 3 arranged on the frame 1, a back pushing device 4 is also provided on the frame 1, the skinning device 3 includes a horizontal skinning shaft 31 and a skinning driving mechanism 32 for driving the skinning shaft 31 to rotate forward and reversely, the skinning shaft 31 is provided with two tensioning chains 33 arranged at intervals, which are used to tighten the skin layers of the two hind legs of the cattle, the back pushing device 4 is arranged between the two tensioning chains 33, and includes a back pushing frame 41 and a back pushing cylinder 42, the back pushing cylinder 42 is arranged on the frame 1, and is used to drive the back pushing frame 41 to extend and then press against the back of the cattle, so that the cattle body is more stable, and the shaking problem when the cattle skin is peeled is avoided, so that the inclination angle of the cattle body is controlled when the cattle is skinned, so that the force of the skinning machine structure is more reasonable, the labor intensity is reduced, and the work efficiency is improved.

[0049] like Figure 5 and Figure 6As shown in the figure, the back-pushing cylinder 42 includes an upper cylinder 421, an upper cylinder housing 422, a lower cylinder 423 and a lower cylinder housing 424. The upper cylinder 421 is arranged inside the upper cylinder housing 422, and the upper cylinder housing 422 is fixed to the frame 1. The piston rod I 4211 of the upper cylinder 421 is arranged downward, and a rotating plate 425 is hinged to its lower end. One side of the rotating plate 425 is provided with a rotating shaft 426, and the rotating shaft 426 is horizontally fixed to the upper cylinder housing 422. The rotating plate 425 can rotate around the rotating shaft 426. The lower cylinder 423 is arranged in the lower cylinder housing 424. The lower end of the rotating plate 425 is fixedly connected to the upper end of the lower cylinder housing 424. The back-pushing frame 41 is arranged below the lower cylinder 423, and the back-pushing frame 41 is fixedly connected to the piston rod II 4231 extending out of the lower end of the lower cylinder housing 424. When the piston rod I 4211 of the driving upper cylinder 421 extends, the piston rod I 4211 pushes the rotating plate 425 to rotate around the rotating shaft 426, so that the lower cylinder 423, the lower cylinder housing 424 and the back-pushing frame 41 as a whole rotate around the rotating shaft 426 until they rotate to a horizontal state, which is used to contact the position of the cow's back to be skinned conveyed, and plays a good role in balancing and supporting the cow body.

[0050] In order to improve the skinning stability, as a preferred embodiment of the present invention, two guide rods 43 are further provided on the back-pushing frame 41. The two guide rods 43 are arranged on both sides of the lower cylinder 423, penetrate the lower cylinder housing 424, and are arranged in parallel with the lower cylinder 423, so as to further enhance the stability of the back-pushing frame 41 against the cow's back.

[0051] As Figure 4 As shown in the structure, as a further preferred embodiment of the present invention, a lifting device 2 is further provided on the frame 1, which includes a lifting reduction gear 21, a main shaft 22, a driven shaft 23, bearing seats 24 at both ends of the main shaft 22, a sprocket 25 and an endless chain 26. The main shaft 22 is horizontally arranged and located at the top of the frame 1. The lifting reduction gear 21 is drivingly connected to the main shaft 22. The driven shaft 23 is located at the lower part of the frame 1, and one driven shaft 23 is arranged on the left and right. Each driven shaft 23 is respectively provided with a sprocket 25 and a bearing seat 24. The sprocket 25 on the main shaft 22 is connected to the sprocket 25 on the driven shaft 23 through the endless chain 26. The left and right ends of the lifting bracket 321 on the skinning device 3 are respectively fixed to the corresponding endless chain 26, and are used to move up and down following the endless chain 26, so as to adjust the skinning position of the skinning device in real time. Of course, by controlling the extension distance of the piston rod II on the lower cylinder 423, the skinning position can also be adjusted to make the skinning of the cow reach the best state.

[0052] As Figure 7As shown in the figure, the peeling drive mechanism 32 in the present utility model includes a lifting bracket 321, a peeling speed reducer 322, a drive chain 323, a main sprocket 324, and a slave sprocket 325. The peeling speed reducer 322 is arranged on the lifting bracket 321. The drive shaft of the peeling speed reducer 322 is connected to the main sprocket 324, and the peeling shaft 31 is connected to the slave sprocket 325. The drive chain 323 is connected between the main sprocket 324 and the slave sprocket 325. By driving the peeling speed reducer to work, the drive chain 323 rotates, and then the peeling shaft 31 rotates. The left and right ends of the lifting bracket 321 are arranged on two annular chains 26 and move up and down following the annular chains 26. Controlling the forward and reverse rotation of the peeling speed reducer 322 can make the tightening chain 33 tighten or loosen the cowhide.

[0053] As Figures 1 to 4 As shown in the figure, the frame 1 in the present utility model includes two parallel longitudinal beams 11. The two longitudinal beams 11 are connected by a cross beam 12. The longitudinal beams 11 form an inclination angle with the ground. Two annular chains 26 are respectively arranged along the length directions of the two longitudinal beams 11. The back-pushing device 4 is arranged at the middle position between the two longitudinal beams 11. When the two tightening chains pull the cowhide to a certain position, the back-pushing device 4 is started, so that the back-pushing device 4 just stably abuts against the middle area of the cow's back. After keeping the cow's back stable, the remaining peeling operation is carried out, greatly improving the peeling efficiency and maintaining the integrity of the cowhide.

[0054] As Figure 1 As shown in the figure, preferably, the peeling shaft 31 of the peeling device 3 is located outside the frame 1, and the back-pushing frame 41 is located below the peeling shaft 31.

[0055] The lifting reducer 21 at the top of the frame 1 of the utility model drives the sprocket 25 on the main shaft 22 to rotate, and the sprocket 25 on the slave shaft 23 is installed at the bottom of the frame 1. The sprocket 25 on the main shaft 22 and the sprocket 25 on the slave shaft 23 are connected by an annular chain 26. The peeling device 3 is connected to the annular chain 26 to realize the lifting and lowering movement of the peeling device 3. The frame 1 is set at a certain inclination angle with the ground, so that the load of the annular chain 26 is reduced, and the annular chain 26 is prevented from offsetting and increasing the friction with the frame 1, and finally reducing the load of the lifting reducer 21. Two bearing seats 24 are set at both ends of the sprocket 25 of the main shaft 22, forming an over-static structure with the lifting reducer 21, which can reduce the load of the lifting reducer 21, optimize the force structure, and protect the lifting reducer. When skinning cattle, the tightening chain 33 is locked on the cattle, and the rotation of the skinning shaft 31 and the descent of the skinning device are controlled. When the skinning device descends to a certain position, the pushing back device 4 is started. The pushing back device 4 realizes the linear reciprocating motion of the pushing back frame 41 through the cooperation of the upper and lower cylinders. The upper cylinder 421 is extended to a certain position so that the lower cylinder 423 is parallel to the ground. At this time, the lower cylinder 423 is extended to push the pushing back frame 41 horizontally until it is against the back of the cattle to be skinned. The rotation of the skinning shaft 31 and the descent of the skinning device 3 are continued to be controlled to peel the cattle from the cattle's back.

[0056] The utility model realizes stable structure and convenient use, solves the technical problem that the deviation or shaking existing in the traditional skinning affects the skinning of cattle, and greatly improves the work efficiency.

[0057] Anything not described in the present invention is applicable to the prior art.
