DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0024] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings:

[0025] like Figures 1-2 As shown, a longan continuous core removal device comprises a feeding mechanism 1 and an upper mechanism 2, wherein the upper part of the feeding mechanism 1 is provided with a fixedly connected upper mechanism 2, and the top of the upper mechanism 2 is provided with an electric control box 21. The feeding mechanism 1 comprises a bottom bin 12 and a transport mechanism, wherein the bottom bin 12 is provided with a transport mechanism.

[0026] The upper mechanism 2 includes a frame 24, a core removal mechanism 23 and a cutting mechanism 22. The cutting mechanism 22 is provided above the loading platform 141, and the cutting mechanism 22 is slidably connected to the frame 24. The core removal mechanism 23 is provided above the cutting mechanism 22, and the core removal mechanism 23 is slidably connected to the frame 24, and the frame 24 is fixedly connected to the feeding mechanism 1. The core-removed longan enters the bottom bin 12 under the action of the transportation mechanism, and is centrally processed through the discharge port 121 provided in the bottom bin 12. The discharge port 121 is tapered toward the ground, which is convenient for collecting the core-removed longan. The bottom bin 12 is provided with a partition 122 at a position corresponding to the discharge port 121. The partition 122 is at an inclined angle to the end face of the discharge port 121. When the fruit core and the fruit pulp fall along the partition 122, the smaller fruit core passes through the partition 122 and the larger fruit pulp accumulates at the bottom of the partition 122. This facilitates the collection of fruit pulp and the removal of fruit cores.

[0027] The bottom of the feeding mechanism 1 is provided with a bottom plate 112, which is fixedly connected to the bottom bin 12 through a plurality of pillars 111 on both sides, and a plurality of casters 11 are provided on the bottom surface of the bottom plate 112. The casters 11 have a built-in brake structure, and the overall mobility of the device can be improved by the casters 11.

[0028] The transport mechanism includes a chain 13 and a transport motor 15. Chains 13 are provided on both sides of the bottom bin 12, and a transport motor 15 is provided outside the bottom bin 12. A rotating shaft 151 is provided at the output end of the transport motor 15, and a sprocket matching the chain 13 is provided on the rotating shaft 151. A plurality of evenly spaced supports 14 are provided in the length direction of the chain 13, and a plurality of loading platforms 141 are provided in the length direction of the support 14, and the loading platforms 141 are rotatably connected to the support 14. The plurality of loading platforms 141 on the support 14 are positioned with grooves matching the longan, and each support 14 can simultaneously transport a plurality of longans to the upper mechanism 2 for the core removal process.

[0029] The transport motor 15 drives the sprocket on the rotating shaft 151 to rotate, and the sprocket drives the multiple supports 14 to move in a circular manner through the chain 13, thereby achieving the effect of continuously supplying longans.

[0030] like Figures 3 to 6 As shown, a lower fixed platform 241 is provided at the lower part of the frame 24, and an upper fixed platform 242 is provided at the upper part. The lower fixed platform 241 and the upper fixed platform 242 are fixedly connected by a plurality of symmetrically distributed guide rods 243. The cutting mechanism 22 and the core removal mechanism 23 are respectively provided with a first guide cylinder 222 and a second guide cylinder 233 that cooperate with the guide rod 243. The cutting mechanism 22 and the core removal mechanism 23 can both move up and down along the guide rod 243.

[0031] The cutting mechanism 22 includes a moving platform 221, a first motor 223, an L-shaped rod 224 and a rotating mechanism. The side of the moving platform 221 is provided with a plurality of symmetrically distributed first guide cylinders 222, and the moving platform 221 is provided with a fixedly connected first motor 223. The screw at the output end of the first motor 223 passes through the moving platform 221 and the lower fixed platform 241, and is threadedly connected with the lower fixed platform 241. A plurality of L-shaped rods 224 are provided at positions corresponding to the loading platform 141 on the moving platform 221. A fixedly connected blade 226 is provided at one end of the L-shaped rod 224 close to the loading platform 141, and the other end passes through the moving plate and is rotatably connected to the rotating mechanism. The rotating mechanism includes a transmission rod 227 and a cylinder. A fixedly connected connecting piece 225 is provided at one end of the L-shaped rod 224 close to the rotating mechanism, and a convex rod is provided on the connecting piece 225, and a positioning hole matching the convex rod is provided on the transmission rod 227. A plurality of L-shaped rods 224 are rotatably connected to the same transmission rod 227 through a connecting piece 225, and the transmission rod 227 is fixedly connected to the output end of the cylinder. When the support 14 moves to the bottom of the cutting mechanism 22, the cylinder drives the transmission rod 227 to rotate the connecting piece 225; the L-shaped rod 224 rotates along with the connecting piece 225, so that the blade 226 turns to the top of the stage 141. The first motor 223 drives the screw to rotate, so that the movable stage 221 moves downward relative to the lower fixed stage 241, so that the blade 226 is inserted into the longan on the stage 141. When the longan rotates relative to the support 14 along with the stage 141, the blade 226 cuts the upper part of the longan, so that the core removal mechanism 23 can completely remove the core.

[0032] The core removal mechanism 23 includes an upper plate 231, a lower plate 232, a second motor 234 and a rotating drum 235. The edge of the core removal mechanism 23 is provided with a plurality of symmetrically distributed second guide cylinders 233, and the upper plate 231 and the lower plate 232 are fixedly connected by the second guide cylinders 233. A fixedly connected second motor 234 is provided on the lower plate 232, and a screw at the output end of the second motor 234 passes through the upper fixed platform 242 and is threadedly connected to the upper fixed platform 242. The core removal mechanism 23 is provided with a plurality of rotating drums 235 at the position corresponding to the loading platform 141, one end of the rotating drum 235 passes through the lower plate 232, and the other end passes through the upper plate 231 and is provided with a driven wheel 237, and the driven wheel 237 is connected to the driving mechanism. When the second motor 234 drives the screw to rotate, the core removal mechanism 23 moves downward as a whole, and at this time, the lower end of the rotating drum 235 is inserted into the longan and the fruit core is stuck. A plurality of spaced convex contacts 2351 are provided on the circumference of the bottom end of the rotating drum 235. When the rotating drum 235 moves downward and approaches the longan, the convex contacts 2351 first pierce the skin of the longan and penetrate into the core. The driving mechanism drives the rotating drum 235 to rotate, so that the core is separated from the flesh; when the core removal mechanism 23 moves upward, the core is separated from the flesh.

[0033] The driving mechanism includes a rotating motor 238 and a synchronous belt 236. The rotating motor 238 is arranged on the lower plate 232 and has a driving wheel at the output end. The driving wheel is connected to a plurality of driven wheels 237 through the synchronous belt 236. The rotating motor 238 drives the driving wheel to rotate. The driving wheel drives the plurality of driven wheels 237 to rotate at the same time through the synchronous belt 236, and the rotating drum 235 rotates with the driven wheels 237. The upper fixed platform 242 is provided with a rod extraction mechanism corresponding to the rotating drum 235. The rod extraction mechanism includes a third motor 25, a core rod 239 and a connecting plate. One end of the core rod 239 passes through the rotating drum 235, and the other end is fixedly connected to the upper end of other core rods 239 through the same connecting plate. The third motor 25 is arranged on the upper fixed platform 242, and the screw at the output end of the third motor 25 is threadedly connected to the connecting plate. The third motor 25 drives the screw to rotate, thereby controlling the up and down movement of the core rod 239. When the core rod 239 moves downward, the fruit core in the rotating drum 235 can be discharged.

[0034] The working principle of the specific embodiment of the present invention is as follows: a plurality of longans are placed on the loading platform 141, and the support 14 drives the loading platform 141 to move along the chain 13 from below the upper mechanism 2 to above the discharge port 121. The upper mechanism 2 performs a core removal process, and the cored longans are discharged from the discharge port 121. The feeding mechanism 1 continuously supplies longans to the upper mechanism 2 to ensure work efficiency.
